Description

  The present invention relates to a laminated workpiece pressurizing apparatus used when pressing is performed in a laminating direction in a state in which plate-like workpieces are laminated, for example, as a single layer plate of a laminated core for a motor.

  In general, laminated cores for motors such as a rotor core and a stator core are integrated by laminating and fixing a large number of (for example, 300) layered plates (workpieces) that have been punched and formed into a predetermined point-symmetric shape. The For example, as described in Patent Document 1, the layer plate is intermittently fed from a upstream side to a downstream side between a plurality of processing units in which a thin metal material is arranged in parallel in a progressive press machine. In addition, predetermined portions are sequentially punched in each processing unit, thereby being punched and formed as a rotor core layer plate or a stator core layer plate. That is, each processing unit of the progressive press processing apparatus is provided with an upper die (movable die) and a lower die (fixed die) so as to be movable relative to each other in the vertical direction. The punch and die having the same are attached and fixed in a state where their center axes coincide with each other. A predetermined processing unit (for example, the processing unit on the most downstream side) positioned downstream of the processing unit after the end material or the like unnecessary for the product shape is punched by the processing unit on the upstream side among the processing units. Thus, a layer plate (such as a layer plate for a stator core) having a product shape is finally punched from a metal material and sequentially stacked on a predetermined stacking jig.

  By the way, since “burrs” are generated at the peripheral edge portions of the respective layer plates when they are sequentially punched and formed, gaps are formed between the respective layer plates stacked on the stacking jig due to the presence of the “burrs”. Such a gap causes a problem such as an increase in magnetic resistance when the laminated core for a motor is used. Therefore, recently, in order to eliminate such a gap between the respective layer plates, as described in Patent Document 2, a lamination in which the above-mentioned layer plates are laminated and pressed in the laminating direction to crush the flash. Work pressure devices have been proposed.

That is, the laminating work pressurizing apparatus described in Patent Document 2 has a presser plate disposed coaxially above a table of a stacking jig for sequentially stacking punched layer boards, and a central portion of the presser plate. A spherical washer is placed in contact with the spherical washer formed from above, and a push-in cap capable of pushing the spherical washer downward in the axial direction is disposed above the spherical washer. Then, by rotating the pushing cap against each layer plate (work) in a laminated state between the table and the presser plate, an axially downward pressing force is applied through a spherical washer. The remaining “burrs” were crushed so as to eliminate the gaps between the layer plates.
Japanese Patent Laid-Open No. 10-4656 (paragraph number [0022], FIG. 1) JP-A-8-294252 (Claim 1, FIG. 1)

  However, in the laminated work pressure device disclosed in Patent Document 2, after each layer plate is laminated on the table of the laminating jig, first, the operation of coaxially arranging the pressers and then the spherical washer is arranged. It was necessary to perform a plurality of operations such as an operation, an operation for arranging the push cap, and an operation for rotating the push cap.

The plate 33 is formed vertically downward. As shown in FIG. 3, when the stacking jig 22B is placed on the rail 20B, the lower surface of the locking plate 33 is gradually inclined from the standby position P2 toward the initial position P1. A tapered copying guide portion 33a extending downward is formed. Further, as shown in FIG. 4B, engagement holes 34 are formed on the lower surface of the disk portion 26 of the stacking jig 22B at two positions opposite to each other by 180 degrees about the axis of the stacking jig 22B. Has been.

  A layer plate support member 35 having a substantially ring shape is fitted and supported on the cylindrical portion 28 so as to be slidable in the axial direction of the cylindrical portion 28. A ring-shaped oil seal (for example, an O-ring) 36 that contacts the outer peripheral surface of the cylindrical portion 28 with a constant frictional force is provided on the inner peripheral surface portion of the layer plate support member 35. Based on the engagement force, the layer plate support member 35 is held at a predetermined height position with respect to the cylindrical portion 28. When the layer plate 19 punched and formed by the processing unit 13D is laminated on the layer plate support member 35 at the lamination position P4, the layer plate is separated by a distance corresponding to the thickness of one layer plate 19. The support member 35 slides downward by the pressing stroke of the punch 15D. Moreover, as shown to Fig.4 (a), after laminating | stacking on the lamellar board support member 35, it integrates by several welding of the outer peripheral surface of the lamellar board support member 35 (three places in this embodiment). In order to recover the laminated layer board 19 from the stacking jig 22B, a hooking hole 37 is formed to hold the hooking jig when the layer board supporting member 35 is pulled up from the lower part to the upper part of the cylindrical part 28. .

  As shown in FIGS. 4A and 4B, the axial center portion of the stacking jig 22B extends in the axial direction so as to penetrate the disc portion 26, the pedestal portion 27, and the cylindrical portion 28. A rod (connecting member) 38 is inserted and supported so as to be reciprocally movable in the vertical direction. An opening portion 39 having a substantially drum shape is formed on the upper surface of the connecting rod 38, and both arcs of the opening portion 39 facing each other are formed in the connecting rod 38 so as to continue downward from the opening portion 39. A circular hole 40 whose diameter is the longest opening diameter between the inner edges is formed. In the present embodiment, the first connecting portion is constituted by the hook-shaped edge 39 a that protrudes in a hook shape above the circular hole 40 out of the inner edge of the opening 39. On the other hand, a circular flange portion 41 having a T-shaped side section is formed at the lower end portion of the connecting rod 38 as a second connecting portion. The connecting rod 38 is connected to the stepped portion 27a formed on the inner peripheral surface of the pedestal portion 27 in a state in which the connecting rod 38 is restricted from being pulled upward by a ring-shaped stop block 42 fixed to the upper end of the cylindrical portion 28. The coil spring 43 is always urged upward by a coil spring 43 interposed between the stepped portion 38a formed on the outer peripheral surface of the connecting rod 38 so as to face the stepped portion 27a.

Next, the carrier position exchange system 21B will be described.
As shown in FIGS. 5 and 6, the transport body position exchanging system 21B has a rail (transport path) 20B provided on the base bracket 44 so as to extend linearly in the horizontal direction, and the rail 20B. A number of rollers 45 are supported so as to be freely rotatable along the longitudinal direction of the rail 20B. Among the left and right rail bodies constituting the rail 20B, the rail body on the side where the jig lifting device 23B is provided (the right rail body in FIGS. 5 and 6) is constant at the work position P3 and the initial position P1. The rail structure is divided by the distance. The moving unit 46 of the jig lifting device 23B moves up and down while supporting the stacking jig 22B through the dividing position at the work position P3, while dividing at the initial position (also serving as a pressure position) P1. The support unit 47 of the laminated work pressurizing device 24 passes through the portion and moves in the vertical direction while supporting the lamination jig 22B. As for the rail 20A of the other transport body position exchanging system 21A, the rail body on the jig lifting device 23A side is similarly divided at the work position P3.

  A straight bar 48B extending in parallel with the rail 20B is bridged on the base bracket 44 via an L-shaped bracket 49 on the side of the rail 20B opposite to the installation side of the jig lifting device 23B. The linear bar 48B (48A) supports a slide member 50 made of a rodless cylinder that constitutes a transport body transfer mechanism together with the linear bar 48B (48A) so as to reciprocate along the longitudinal direction of the linear bar 48B. Yes. The slide member 50 includes a fixed locking claw 51 and a movable locking claw 52 that can be locked so as to sandwich the locking plate 33 provided on the stacking jig 22B (22A) serving as a transport body from both front and rear sides. Projecting in the direction of 20B (20A). The positional relationship between the fixed locking claw 51 and the movable locking claw 52 is such that the fixed locking claw 51 is positioned on the standby position P2 side and the movable locking claw 52 is on the initial position P1 side in the direction along the rail 20B (20A). It is provided so that it may be located in. Further, as shown by a solid line in FIG. 6, the movable locking claw 52 is locked to a front end surface (front end surface in FIG. 6) of the locking plate 33, and a two-dot chain line in FIG. 6. As shown in FIG. 2, the pin 53 is rotatably supported so as to be able to take a non-locking position in contact with the lower surface of the locking plate 33 from below, and is always locked by the urging force of the winding spring 54.

When the fixed locking claw 51 and the movable locking claw 52 are sandwiched from the front and rear sides, the lamination jig 22B (22A) is locked and held. Then, in the latched holding state, when the slide member 50 reciprocates along the straight bar 48B (48A), the stacking jig 22B (22A) moves from the initial position P1, the standby position P2, the working position P3, It is transferred to the initial position P1... (Hereinafter repeated). Further, when the slide member 50 moves from the direction of the standby position P2 to the locking plate 33 of the stacking jig 22B (22A) on the rail 20B (20A) and the movable locking claw 52 comes into contact, it is movable. The locking claw 52 performs a displacement operation so as to get over the locking plate 33 from the standby position P2 side to the initial position P1 side while following the scanning guide portion 33a.

Next, the jig lifting device 23B will be described.
As shown in FIGS. 2, 7, and 9, the jig lifting device 23 </ b> B includes a casing 55 whose front side (the front side in FIGS. 2 and 7, the right side in FIG. 9) and the lower side are open. A motor (drive source) 56 is housed and disposed in the lower part of the casing 55, and a bearing 57 is provided in the upper part of the casing 55 at a position corresponding to the output shaft (not shown) of the motor 56. A male screw rod 58 extending in the vertical direction is connected to the output shaft of the motor 56, and the male screw rod 58 rotates forward and backward based on the driving force of the motor 56 with its upper end supported by the bearing 57. It is configured. The male screw rod 58 is screwed with a block-shaped drive body 59 having a female screw hole (not shown) having an inner diameter corresponding to the outer diameter of the male screw rod 58. That is, the drive body 59 is configured to be movable up and down along the vertical direction in which the male screw rod 58 extends as the male screw rod 58 rotates forward and backward based on the driving force of the motor 56. Further, on the front side of the driving body 59, a convex plate portion 60 whose tip is narrower than the driving body 59 is formed to project in the horizontal direction, and the convex plate portion 60 has a horizontal direction (in FIG. A plurality (three in the present embodiment) of insertion holes 60a are formed in a direction perpendicular to (see FIG. 10). Further, on the left side surface (the right side surface in FIG. 7) of the driving body 59, a front end surface (upper end surface) 61a that functions as an abutment guide portion is lowered to the front side, and is a tapered plate cam (pushing). A moving member 61 is attached in a vertical posture.

  As shown in FIGS. 7 to 10, an elevating plate 62 (a part of the moving body) 62 having a rectangular shape in front view (see FIG. 7) is disposed on the front side of the driving body 59. In FIG. 7, for convenience of explanation, a cross-sectional view of a member (for example, an arm-like plate described later) to be cross-sectionally illustrated on the front surface of the elevating plate 62 is omitted. A vertically long groove 63 having substantially the same width as the tip of the convex plate portion 60 is perpendicular to a position corresponding to the convex plate portion 60 of the drive body 59 on the back surface side (side facing the drive body 59) of the elevating plate 62. It is formed in the direction. In the longitudinal groove 63, the tip of the convex plate portion 60 of the driving body 59 is inserted so as to be slidable in the vertical direction, and within the vertical length range (fixed range) of the longitudinal groove 63, The driving body 59 and the elevating plate 62 are assembled so as to be movable relative to each other in the vertical direction. On the other hand, from the position corresponding to the vertically long groove 63 at the upper end of the elevating plate 62, a flange 64 having substantially the same width as the convex plate 60 is formed in the horizontal direction. A plurality (three in this embodiment) of rods 65 are supported in a suspended manner in a state where the lower end portions are loosely inserted into the respective insertion holes 60 a of the convex plate portion 60. A coil spring (biasing member) 66 is disposed on the outer periphery of each rod 65 so that the drive body 59 and the lifting plate 62 are always within the vertical length range (a certain range) of the longitudinal groove 63. It is set as the structure biased so that it may mutually space apart in the up-down both directions (refer FIG. 7, FIG. 9).

  Further, at the position corresponding to the left and right side walls 55a of the casing 55 on the back surface side of the elevating plate 62, a concave groove 68 is provided to be engaged with each vertical guide 67 attached and fixed to the front end surface of the left and right side walls 55a. Are formed in the vertical direction. Therefore, when the male screw rod 58 rotates based on the driving force of the motor 56 and the drive member 59 moves up and down with the forward and reverse rotation of the male screw rod 58, the drive member 59 moves along with the up and down movement of the drive member 59. The elevating plate 62 (that is, a part of the moving body) is also moved up and down along the vertical direction (predetermined direction) while the groove 68 is slidably guided by the vertical guide 67. In this case, for example, if a load corresponding to the weight of the stacking jig 22B is applied to the lifting plate 62 side, it is conceivable that the coil spring 66 is contracted by a compressive force due to the load. However, in this embodiment, the coil spring 66 having a biasing force larger than the compressive force based on such a load is employed. Accordingly, when the driving body 59 moves upward, the driving body 59 follows the lifting plate (part of the moving body) 62 (that is, from below) so that the driving body 59 follows and moves. The positional relationship shown in FIG. 9 is maintained between the driver 59 and the lift plate 62 by the biasing force of the coil spring 66.

  As shown in FIGS. 8 to 11, an arm-shaped plate 69 is formed on the front surface side of the elevating plate 62 so as to protrude in the horizontal direction. In the case of FIG. 11, a rotating table (rotating body) 70 capable of mounting and supporting the stacking jig 22B is provided on the lower surface side so as to be horizontally rotatable around a vertical axis. In the present embodiment, the movable body 46B (46A) moves in the vertical direction (predetermined direction) while the stacking jig 22B (22A) is supported by the elevating plate 62, the arm plate 69, the rotary table 70, and the like. Is configured. Further, the moving body 46B (46A) and the driving body 59 allow the stacking jig (conveyance body) 22B (22A) at the work position P3 to be placed at the work position P3 or from the rail 20B (20A). A moving unit 46 is configured to reciprocate so as to be placed at the removed retracted position (in this embodiment, the stacking position P4). The retreat position may be a position set between the processing unit 13D and the work position P3, and is not necessarily limited to the stacking position P4. Further, the stacking jig 22B (22A) is moved to the rail (22A) in a state where the stacking jig (transport body) 22B (22A) at the work position P3 is supported by the moving unit 46 and the motor (drive source) 56. (Conveyance path) 20B (20A) A retraction mechanism for retreating to a retreat position deviated from the top is configured.

  As shown in FIGS. 12 and 18, a base block 192 is fixedly supported on the retaining disc 190, and a mounting bracket 193 having an L shape in plan view is fixed on the base block 192. It is supported. On the other hand, a mounting bracket 194 having an L shape in side view is fixedly supported on the annular plate 188. A cylinder 195 is disposed between the mounting brackets 193 and 194 so as to be slightly lifted above the annular plate 188 and the retaining disk 190, and the base end of the cylinder 195 is located at the tip of the mounting bracket 193. The tip end of the cylinder rod 196 is rotatably supported by the tip of the mounting bracket 194 while being supported rotatably. That is, when the cylinder 195 is driven and the cylinder rod 196 is contracted from the state shown in FIG. 18, the annular plate 188 is rotated clockwise in FIG. As the annular plate 188 rotates clockwise, the narrow neck portion 187a of the hook bar 187 is guided radially inward by the skew guide hole 191. As a result, the hook bar 187 has the wide guide hole. 185 and the narrow guide hole 186 are guided to move inward in the radial direction. 12, 17, and 18, a lower stopper bar 197 is erected from one place on the outer peripheral edge of the upper disk 179, and from one place on the outer peripheral edge of the fixed plate 176. The upper stopper rod 198 is suspended on the movement locus of the lower stopper rod 197 when the upper disc 179 is rotated. These stopper rods 197 and 198 are provided based on the rotational drive of the servo motor 177 so as to restrict the upper disk 179 and the like from rotating more than once during the welding process described below. .

Next, the welding device 25 will be described.
As shown in FIGS. 12 and 13, a rectangular hole 199 is formed in the vertical plate portion 126 at a position slightly above the position where the bearing 133 is provided on the upper extension line of the elongated hole 138. The casing 200 of the welding apparatus 25 is attached to the back surface side of the vertical plate portion 126 so as to correspond to the position of the rectangular hole 199. A pair of upper and lower horizontal guide plates 201 and 202 are provided in the casing 200, and the moving block 204 that supports the welding torch 203 moves forward and backward along these horizontal guide plates 201 and 202. . That is, the moving block 204 moves forward during the welding process, and as shown in FIG. 4, the welded portion 19b formed on the outer periphery of each layer plate 19 in which the welding torch 203 is laminated is welded. Yes.

  Therefore, next, with respect to the operation of the progressive press processing apparatus 11 of the present embodiment configured as described above, mainly the transport body position exchanging system 21B, the stacked workpiece rolling device 125, the movable body locking device 78, The description will be focused on each operation of the laminated work pressure device 24. First, the operation of the transporter position exchanging system 21B will be described with reference to FIG. In FIGS. 19A to 19F, only the portions necessary for the respective explanations are extracted and schematically shown for the transporter position exchanging system 21B and the stacking jig 22B. Moreover, in each figure of Fig.19 (a)-(f), the upper illustration content is the planar view of the operating condition of the conveyance body position exchange system 21B, and the lower illustration content is the same conveyance. The operation state of the body position exchange system 21B is schematically viewed from the side.

  First, in FIG. 19A, two stacking jigs 22B are placed on the rail 20B, and one stacking jig 22B is placed at the standby position P2 (hereinafter referred to as “jig A” in the explanation using FIG. And the other stacking jig 22B (hereinafter referred to as “jig B” in the description using FIG. 19) is arranged at the work position P3. Then, the fixed locking claw 51 and the movable locking claw 52 are locked to the locking plate 33 of the empty jig A waiting at the standby position P2 so as to be sandwiched from both the front and rear sides, and the jig located at the work position P3. On the tool B, the layer plate 19 is already laminated. That is, in the state of FIG. 19A, the empty jig A at the standby position P2 waits for the next transfer to the work position P3, while the layer plate 19 at the work position P3 is laminated. A state is shown in which the completed jig B is waiting to be transferred to the initial position (also serving as a welding position and a collection position) P1.

  Now, when the slide member 50 moves from the standby position P2 to the work position P3 along the straight bar 48B from the state shown in FIG. 19A, as shown in FIG. The jig B is pushed in the direction of the initial position P1 by the empty jig A held and held by the locking claws 51 and 52 together with the slide member 50 and transferred to the working position P3. Accordingly, the pushed jig B is slightly moved on the rail 20B in the direction of the initial position P1 while the layer plates 19 are laminated, and is moved on the rail 20B between the work position P3 and the initial position P1. Stop.

  Then, although not shown in FIG. 19C, the moving unit 46 of the jig lifting device 23B supports the empty jig A stopped at the work position P3 in place of the jig B. Then rise. That is, the jig A is retracted upward. As a result, the slide member 50 is moved from the working position P3 to the initial position P1 because the locking plate 33 of the jig A moves from the fixed locking claw 51 and the movable locking claw 52 to the upper stacking position P4. Movement in the direction is allowed.

  Then, as shown in FIG. 19D, when the slide member 50 moves along the straight bar 48B in the direction from the working position P3 to the initial position P1, first, the movable locking claw 52 is moved to the rail during the movement. It abuts on the locking plate 33 of the jig B stopped between the work position P3 and the initial position P1 on 20B. Then, a taper-shaped copying guide portion 33a is formed on the lower surface of the locking plate 33 so as to be gradually inclined downward from the standby position P2 toward the initial position P1. Is displaced so as to follow the profile of the copying guide portion 33a, and becomes a non-locking mode position (a position indicated by a two-dot chain line in FIG. 6) in contact with the lower surface of the locking plate 33 from below.

  Then, when the slide member 50 further moves in the direction of the initial position P1 from that state, the movable locking claw 52 gets over the locking plate 33 in the jig B from the working position P3 side to the initial position P1 side, and FIG. As shown in FIG. 6E, both the fixed locking claw 51 and the movable locking claw 52 are in the locking mode position (the position shown by the solid line in FIG. 6) with respect to the locking plate 33 of the jig B. As a result, the jig B on which the layer plate 19 is laminated is transferred to the initial position P1 by the slide member 50 while being held and held by the both locking claws 51 and 52. And in this initial position P1, the process (for example, welding process and collection | recovery process) of the next process is performed to the layer board 19 on the jig | tool B. FIG. At this time, the layer plates 19 are sequentially stacked on the jig A which is at the work position P3 and is retreated from the rail 20B to the upper stacking position P4.

  Then, the jig B in which the layer plate 19 is recovered and emptied at the initial position P1 is arranged on the front and rear sides of the locking plate 33 with the fixed locking claws 51 as shown in FIG. 19 (f). The slide member 50 is transferred from the initial position P1 to the standby position P2 while being held by the movable locking claw 52. In the middle of the transfer, it passes through the work position P3. At that time, the jig A at the work position P3 is retracted to the upper stacking position P4. There is no hindrance when the tool B is transferred to the standby position P2. After that, when the jig A that has been retracted to the upper stacking position P4 at the work position P3 finishes stacking the layer plates 19 and moves down onto the rail 20B, the state returns to the state of FIG. However, the case of FIG. 19A is a positional relationship in which the mutual positions of both jigs A and B on the rail 20B are exchanged. In the same manner, the exchange of the mutual positions of the two jigs A and B on the rail 20B is repeated.

Next, the operation of the stacked workpiece rolling device 125 in the jig lifting device 23B will be described with reference mainly to FIGS. 3, 8, 10, 20, and 21. FIG.
As shown in FIG. 3, when the empty stacking jig 22B is transferred to the work position P3 on the rail 20B, the moving unit 46 positioned below the rail 20B at the work position P3 is moved to the motor 56. By the rotation of the male screw rod 58 based on the rotational drive, the drive body 59 moves upward as the drive body 59 moves upward. Then, the stacking jig 22 </ b> B moves upward with respect to the rail 20 </ b> B together with the moving unit 46 while the disk portion 26 is supported from below by the rotary table 70 in the moving unit 46. And the lamination position P4 (position shown to FIG. 22 (a) (b)) in which the protrusion 31 on the disc part 26 of the said lamination jig | tool 22B fits into the stopper hole 32 of the base plate 12 of a metal mold | die apparatus (processing unit). ), The layered plates 19 are sequentially stacked on the stacking jig 22B at the stacking position P4. At that time, in the present embodiment, due to the action of the laminated workpiece rolling device 125, on the lamination jig 22 </ b> B (specifically, on the layer plate support member 35 fitted to the cylindrical portion 28). A large number (for example, 300 sheets) of layer plates 19 are laminated (so-called “rolling”) in a state where the phases are different every predetermined number (for example, every 100 sheets). Hereinafter, the transposition operation will be described.

  First, when the moving unit 46 is located below the rail 20B, as shown in FIG. 8, the cam roller 85 configured to move integrally with the shaft (displacement member) 81 is a jig lifting device 23B. The casing 55 is positioned below the fixed unit 117 provided with the cam mechanism 124. When the moving unit 46 starts to rise, the cam roller 85 also starts to rise, and enters the vertical guide portion 118 of the fixed unit 117 from the lower inlet 118b in the middle of the raising. As the moving unit 46 further rises, the cam roller 85 further moves up in the vertical guide portion 118. Then, the cam roller 85 comes into contact with the swinging member 122 biased and held in an oblique posture that closes the vertical guide portion 118 from below, and this swinging member 122 resists the biasing force of the winding spring 123 as shown in FIG. Then, it continues to rise while being pushed to the vertical posture shown by the two-dot chain line, and then moves upward from the upper inlet 118a of the vertical guide portion 118 to the fixed unit 117.

  On the other hand, when a predetermined number (for example, 100) of the layer plates 19 are stacked on the stacking jig 22B at the upper stacking position P4, the motor 56 is driven to rotate in the opposite direction to the above, and the male screw rod 58 also rotates in the opposite direction. Therefore, this time, the driving body 59 moves downward, so that the moving unit 46 also moves downward while supporting the stacking jig 22B on the rotary table 70, and when it is lowered to the position where the fixed unit 117 is provided, The cam roller 85 that has moved downward also enters the vertical guide 118 from the upper inlet 118a. Then, the cam roller 85 that has entered the vertical guide portion 118 is supported by the swinging member 122 that is biased and held in an oblique posture that closes the vertical guide portion 118 as described above at the upper merging position 120 in the vertical guide portion 118. This time it comes in contact from above. Then, the cam roller 85 is engaged and guided from the vertical guide portion 118 toward the bypass guide portion 119 by the swinging member 122 having an oblique posture as the moving unit 46 further moves downward.

  FIG. 20 illustrates the movement position of the cam roller 85 in this case as a point. As shown in FIG. 20, the cam roller 85 that has entered the vertical guide portion 118 from the upper inlet 118a is first guided by the swing member 122 from the position “a” corresponding to the upper merging position 120 to the position “b”. The direction of engagement guidance is switched to the direction of. Thereafter, the cam roller 85 passes from the position “B” through the position “C” to the position “D”, and the cam roller 85 inclines from the vertical direction (in this case, the shaft 81 is moved to the surface of the lifting plate 62 ( Engagement guidance is performed by the upper skew guide portion 119a of the bypass guide portion 119 in the direction of projecting from the front surface). Then, from the position “d” to the position “e”, the intermediate guide portion 119b is engaged and guided vertically downward, and then the position “f” corresponding to the lower joining position 121 from the position “e”. The cam roller 85 is engaged and guided again from the vertical direction to the skew direction by the lower skew guide portion 119c. When the cam roller 85 is engaged and guided in the oblique direction by the lower skew guide portion 119c, the shaft 81 moves horizontally (retracts) from the front surface (front surface) side to the rear surface side of the lift plate 62. )

  When the cam roller 85 is engaged and guided by the cam mechanism 124 as described above, the following rollover-related operation is performed on the lower surface side of the arm-shaped plate 69 of the moving unit 46. In the following description of the roll-off related operation, when the rotation direction is “clockwise” or “counterclockwise”, it means “clockwise” or “counterclockwise” in FIGS. Shall. When the movement mode is “forward movement” or “reverse movement”, the “forward movement” and “reverse movement” in the case where the rightward direction in FIGS. 21A and 21B is the forward direction and the leftward direction is the backward direction. ".

  First, when the cam roller 85 moves from the position “I” to the position “B”, the shaft 81 moves from the surface side of the lift plate 62 against the urging force of the coil spring 88 as shown in FIG. The robot moves forward in a protruding direction (that is, a forward direction) by a distance corresponding to the horizontal interval between the position “A” and the position “B”. Then, the horizontal movement portion 89 of the front side connection bracket 86 connected and fixed to the shaft 81 is also moved forward by the same distance, and the pushed piece portion 99a of the rotation lock member 99 is moved by the push pin 97 provided at the tip portion thereof. It is pushed.

  Then, as shown in FIG. 21 (a), the rotation lock member 99 attaches the winding spring 101 from the rotation restricting position indicated by the two-dot chain line to the rotation allowable position indicated by the solid line with the support pin 100 as the rotation center. It rotates in the clockwise direction against the force and causes the lock convex portion 99 b to come out of the lock portion 105 of the large-diameter cylindrical portion 102 in the stepped cylindrical member 104. Then, as a result of releasing the rotation restricted state of the stepped cylinder member 104, the rotation table 70 supporting the stacking jig 22B on the upper surface side of the arm-shaped plate 69 is also released from the rotation restricted state and can freely rotate. It is said.

  When the cam roller 85 is further moved from the position “B” to the position “C”, the cam roller 85 is in the long groove 90 of the horizontal moving portion 89 until the cam roller 85 moves to the position “C”. The edge on the front connection bracket 86 side of the long groove 90 abuts on the rectangular frame 92 that has only been slid. Then, until the cam roller 85 moves to the position “C” from the contact point, the rectangular piece 92 is further moved forward together with the horizontal moving portion 89, so that the pin 91 of the rectangular piece 92 is moved. The link plate 111 slides in the long hole 112 of the link plate 111, and the link plate 111 rotates counterclockwise while resisting the urging force of the coil spring 116 around the support shaft 110.

  Then, as the link plate 111 rotates, the slide plate 108 that is operatively connected to the link plate 111 by engaging the long hole 113 and the pin 109 is connected to the shaft 81 (and the horizontal moving portion 89). Move horizontally in the direction opposite to the horizontal movement direction (forward direction). Then, the stepped tube member 104 in a relationship in which the rack 107 of the slide plate 108 and the pinion 106 of the small diameter tube portion 103 mesh with each other is rotated counterclockwise, and the turntable 70 rotates together with the stepped tube member 104. Accordingly, since the stacking jig 22B supported on the turntable 70 also rotates based on the rotation of the turntable 70, the layer plate 19 stacked on the stacking jig 22B also has a vertical axis passing through the center thereof. Is rotated together with the stacking jig 22B and the rotary table 70 (stepped cylindrical member 104).

  When the cam roller 85 further moves from the position “c” to the position “d”, the pushed piece 99a of the rotation lock member 99 has been pushed until that time. As the push pin 97 is displaced in the clockwise direction of the rotation lock member 99, the push pin 97 is finally detached from the pushed piece 99a and advances forward from the pushed piece 99a. Then, the rotation lock member 99 returns and rotates counterclockwise by the urging force of the winding spring 101, and is attached to the outer peripheral surface of the large-diameter cylindrical portion 102 of the stepped cylindrical member 104 as shown in FIG. It abuts in a biased state. Specifically, when viewed from the lock portion 105 that has been fitted and locked before the current roll-up operation, it comes into contact with a position slightly ahead of the next lock portion 105 on the rear side in the clockwise direction.

  Then, when the cam roller 85 moves to the position “d” from that state, the shaft 81 (and the horizontal moving portion 89) further advances from the state shown in FIG. 21B, and the slide plate 108 also moves to the position shown in FIG. , The stepped cylinder member 104 rotates counterclockwise. Then, the lock convex portion 99b of the rotation lock member 99 is fitted and locked to the next lock portion 105, and the stepped cylindrical member 104 and the rotary table 70 are brought into a rotation restricted state. Accordingly, at this time, the stacking jig 22B on the turntable 70 is moved from the position state before the rolling operation to a certain direction (counterclockwise) by a certain angle (the ear portion 19a of the layer plate 19 and the lock portion 105 are respectively The vertical axis passing through the center of the layer plate 19 is rotated about the rotation center by the formed angular interval of 120 degrees. This state is maintained until the cam roller 85 moves from the “d” position to the “e” position.

  Next, when the cam roller 85 moves from the position “e” to the position “f”, the shaft 81 (and the horizontal moving portion 89) moves backward. As the plate 111 rotates in the clockwise direction, the slide plate 108 also moves horizontally in the direction on the right side in FIGS. Accordingly, the small-diameter cylindrical portion 103 of the stepped cylindrical member 104 in which the rack 107 of the slide plate 108 and the pinion 106 mesh with each other rotates in the clockwise direction. However, the large-diameter cylindrical portion 102 configured to rotate integrally with the rotary table 70 in both the forward and reverse directions in the stepped cylindrical member 104 has a small diameter due to the action of the latch mechanism provided in the stepped cylindrical member 104. Even if the cylinder portion 103 rotates clockwise, it does not rotate clockwise together with the small diameter cylinder portion 103. As a result, the rotary table 70 also does not rotate integrally in the clockwise direction when the small-diameter cylindrical portion 103 of the stepped cylindrical member 104 rotates in the clockwise direction. Therefore, the stacking jig 22B on the rotary table 70 also rotates in the clockwise direction. There is no rotation.

  Further, when the shaft 81 (and the horizontal moving portion 89) moves backward due to the movement of the cam roller 85 from the “e” position to the “f” position, the above-described hung down from the front end portion of the horizontal moving portion 89. The push pin 97 also moves backward, and contacts the pushed piece 99a of the rotation lock member 99 during the backward movement. Then, as described above, the upper end surface of the push pin 97 and the lower end surface of the driven piece 99a are respectively formed with slopes that form a downward slope toward the rear side. As a result, the push pin 97 is displaced downward in the axial direction against the urging force of the coil spring 98 and gets over the pushed piece 99a. Therefore, when the push pin 97 contacts the pushed piece 99a of the rotation lock member 99, the backward movement of the shaft 81 (and the horizontal moving portion 89) is not hindered.

  Then, after the cam roller 85 has moved to the position “F”, when the moving unit 46 further moves downward, the cam roller 85 comes out of the cam mechanism portion 124 via the lower inlet 118b of the vertical guide portion 118. Thereafter, when the moving unit 46 is moved up to further laminate the layer plate 19 on the laminating jig 22B, the cam roller 85 moves the vertical guide portion 118 in the vertical upward direction, and hits the swinging member 122 from below. After coming in contact and pushing it out, the cam mechanism 124 exits upward via the upper inlet 118a of the vertical guide 118. Thereafter, when the next predetermined number (for example, 101 to 200) of layer plates 19 are stacked at the stacking position P4, the moving unit 46 descends again while supporting the stacking jig 22B. Similar rollover related operations are repeated.

  As described above, in the stacked workpiece rolling device 125 in the jig lifting device 23B, the cam unit 124 is provided with the moving unit 46 every time a predetermined number (for example, 100) of the layer plates 19 are stacked at the stacking position P4. The up and down movement is repeated so that the cam roller 85 passes through the fixed unit 117 in the vertical direction. Then, when the shaft 81 moves back and forth in the horizontal direction based on the up-and-down movement of the moving unit 46, the arm-like plate 69 is provided with a latch mechanism on the lower surface side of the arm-like plate 69, and the arm-like plate member 104 is provided. The rotary table 70 that supports the stacking jig 22B on the upper surface side of the plate 69 is rotated by a predetermined angle (120 degrees in this embodiment) in a predetermined direction. That is, the rotary table 70 is rotated by the driving force generated based on the horizontal movement (displacement operation) of the shaft 81. Accordingly, the layer plates 19 sequentially stacked on the stacking jig 22B are stacked in a state where the phases are different for every predetermined number (100 in the present embodiment).

Next, the operation of the movable body locking device 78 in the jig lifting device 23B will be described with reference mainly to FIGS. 8, 9, 22 (a) and 22 (b).
Now, as described above, the layered plate punched and formed on the laminating jig 22B raised to the laminating position P4 immediately below the pressure unit 13D based on the ascending movement of the moving unit 46 at the work position P3 on the rail 20B. 19 are sequentially stacked. At that time, the layer plate support member 35 slidably fitted and supported by the cylindrical portion 28 of the stacking jig 22B while the layer plate 19 is stacked and supported by the pressing stroke of the punch 15D is provided on the layer plate 19. The sheet is pressed downward by a distance corresponding to the thickness of the sheet. Accordingly, it is necessary to position and lock the moving body 46B of the moving unit 46 supporting the stacking jig 22B in the vertical direction so as to face the pressing stroke of the punch 15D. In the case of this embodiment, the positioning lock of the moving body 46B in this case is performed by the moving body locking device 78.

  That is, when the moving unit 46 moves upward while supporting the stacking jig 22B on the rotary table 70 of the moving body 46B at the working position P3 and reaches the stacking position P4 shown in FIG. A protrusion 31 projecting upward from the disc portion 26 of 22B is fitted into the stopper hole 32 formed in the lower surface of the base plate 12. Therefore, at the height position where the protrusion 31 is fitted in the stopper hole 32, the moving body 46B composed of the rotary table 70 and the like supporting the stacking jig 22B is restricted from further upward movement. At this time, in the casing 55, a sloped tip end surface (upper end surface) 61a of the taper plate cam 61 attached to the side surface of the drive body 59 constituting the moving unit 46 together with the moving body 46B is a slider 73. The position of the taper plate cam 61 at this time is indicated by a two-dot chain line in FIG.

  Then, from the state of FIG. 22 (a), when the drive body 59 moves upward with the further rotation of the male screw rod 58, the flange portion 64 of the elevating plate 62 in the moving body 46B and the convex plate portion 60 in the drive body 59. The coil spring 66 interposed therebetween is bent and deformed. That is, the coil spring 66 contracts from the extended state shown in FIG. 9, and the convex plate portion 60 of the driving body 59 slides upward in the longitudinal groove 63 and comes into contact with the upper edge of the longitudinal groove 63. Then, the taper plate cam 61 is also moved upward by the upward movement of the driving body 59 accompanying the movement (sliding) of the convex plate portion 60, so that the engagement roller 74 is pushed forward by the taper plate cam 61. FIG. 9 shows each position state of the taper plate cam 61 and the engaging roller 74 at this time. Then, since the engagement roller 74 is moved forward by being pushed by the taper plate cam 61, the slider 73 that is integrated with the engagement roller 74 also moves forward in the horizontal guide groove 71 of the block body 72, and its tip end portion is The movable body 46B is inserted and locked in the locking hole 77 of the elevating plate 62. That is, the state shown in FIG. At this time, the drive of the motor 56 is stopped.

  Thereafter, when a predetermined number of layer plates 19 are stacked on the stacking jig 22B at the stacking position P4, the motor 56 is driven again, and the male screw rod 58 is rotated in the opposite direction. Therefore, the drive body 59 moves downward from the state shown in FIG. 22B, and the taper plate cam 61 also moves downward to release the contact state with the engagement roller 74. Then, due to the urging force of the tension spring 76, the slider 73 moves from the movement restricting position shown in FIG. 22 (b) in which the tip end portion is inserted and locked into the locking hole 77 to the movement allowable position shown in FIG. 22 (a). Move backwards. At this time, as shown in FIG. 22 (a), the convex plate portion 60 of the driving body 59 is in a position where it abuts and locks against the lower edge of the longitudinal groove 63 with respect to the lifting plate 62. . Therefore, from the state of FIG. 22A, when the drive body 59 moves downward as the male screw rod 58 further rotates in the reverse direction, the moving body 46B also has the fixed unit 117 provided with the cam mechanism portion 124. Move down in the direction of the position.

  As described above, the movable body locking device 78 in the jig lifting device 23B is positioned when the movable body 46B stops at the stacking position (predetermined position) P4 for positioning and holding (locking) the movable body 46B. The slider 73 that functions as a locking member is directly pushed by the taper plate cam 61 that functions as a pushing member. Then, the slider 73 is engaged with the moving body 46B by the pushing operation and moved to a movement restricting position where the movement is restricted, and from the movement allowable position where the moving body 46B is disengaged and allowed to move. Displace. Therefore, the moving body 46B of the moving unit 46 that supports the stacking jig 22B at the stacking position P4 is reliably positioned and locked in the vertical direction facing the pressing stroke of the punch 15D.

Next, the operation of the laminated work pressure device 24 will be described with reference mainly to FIGS. 12 to 15, 23, and 24.
Now, the stacking jig 22B, which is raised to the stacking position P4 by the jig lifting device 23B at the work position P3 and stacks the layer plates 19, then moves on the rail 20B to the slide member 50 of the transport body position exchanging system 21B. Thus, the sheet is transported to an initial position (also a welding position and a collection position) P1. Then, at the initial position P1, the laminated plate pressurizing device 24 presses the laminated plate 19 in the laminated direction, and in this pressurized state, the respective laminated plates 19 are welded and fixed by the welding device 25, and the motor Integrated as a laminated core.

  First, in the stacking jig 22B conveyed from the work position P3 to the initial position P1 on the rail 20B, the circular flange portion 41 of the stacking jig 22B has a passage port 169 of the cylindrical block 150 in the support unit 47 shown in FIG. , And enters and stops at a position where it is coaxial with the retracting rod 152 in the cylindrical block 150. That is, in the position shown in FIG. 15, the stacking jig 22B is in a state in which the connecting rod 38 arranged on the axial center is connected to the retracting rod 152 on the support unit 47 side so as not to be vertically separated, The support unit 47 is placed and supported on the cylindrical block 150 so as not to move upward. Then, the motor 132 on the base plate 130 is driven to rotate, and the male screw rod 134 rotates, so that the arm-shaped plate portion 145 rises together with the lifting block 139 and the lifting plate 141.

  Then, as the arm-shaped plate portion 145 rises, the ring plate 157 placed on the arm-shaped plate portion 145 rises against the urging force of the coil spring 159, and the ring plate 157 The upper surface is in contact with the lower end surface of the cylindrical block 150. As the ring plate 157 rises, the vertical rod 161 erected on the ring plate 157 protrudes from the upper end surface of the cylindrical block 150 and is formed in the engagement hole formed in the lower end surface of the stacking jig 22B. 34 is inserted and locked. Therefore, at this point, the stacking jig 22B placed and supported on the cylindrical block 150 is moved horizontally from above the cylindrical block 150 by the vertical rod 161 being inserted and locked in the engagement hole 34. Movement is also restricted. At this time, as the arm-shaped plate portion 145 rises, the vertical bar 163 shown in FIGS. 12 and 13 also rises, and the locking pin 165 is locked to the locking hole 168 of the L-shaped bracket 167. Becomes shallower. Specifically, the engagement state is shallower than the engagement state (deep engagement state) shown in FIG.

  Then, when the male screw rod 134 is further rotated by the driving force of the motor 132 from that state, and the arm-like plate portion 145 is raised to a certain height position, the pressurizing unit 129 is pressed as shown in FIG. The connecting bar 182 of the unit 129 is inserted into the circular hole 40 from the opening 39 of the stacking jig 22 </ b> B that is placed and supported on the cylindrical block 150. At this time, the lower end surface of the surface pressure block 181 on the pressure unit 129 side is in a state of facing the upper surface of the uppermost layer plate 19 on the stacking jig 22B through a slight gap, and is still They are not in surface contact with each other. Then, on the pressure unit 129 side, the servo motor 177 is driven to rotate, and the connecting bar 182 is rotated 90 degrees together with its output shaft 178 (and the upper disk 179, the lower disk 180, and the surface pressure block 181). Only rotate. Therefore, the connecting bar 182 has a position aspect that overlaps in the vertical direction with the connecting rod 38 located in the cylindrical block 150 of the stacking jig 22B and the flange-shaped edge 39a of the opening 39 of the connecting rod 38, As a result, the connecting bar 182 and the connecting rod 38 are connected so that they cannot be separated in the vertical direction.

  Then, the air cylinder 149 on the top plate portion 127 on the pressurizing unit 129 side is brought into a pneumatic operation free state, while the air cylinder 149 on the support unit 47 side is driven, and the retracting rod 152 is moved vertically downward. Retracted to actuate. For example, the pulling operation is performed vertically downward with a pulling force of about 20 tons. Then, the connecting rod 38 in the stacking jig 22B connected to the drawing rod 152 so as not to be vertically separated, and the pressure unit 129 side connected to the connecting rod 38 so as not to be vertically separated are connected. The connecting bar 182 moves vertically downward integrally with the retracting rod 152. That is, the retracting rod 152 moves downward in the cylindrical block 150, the supporting cylindrical portion 147 and the air cylinder 149 while contracting the coil spring 156 below the large diameter portion 154. Further, the connecting rod 38 is pulled downward by the pulling rod 152 in the cylindrical portion 28, the pedestal portion 27 and the disc portion 26 while contracting the coil spring 43 below the step portion 38a. Moving. Similarly, the connecting bar 182 is drawn downward by the connecting rod 38 and moved vertically downward, and the surface pressure block 181 is brought into contact with the upper surface of the uppermost layer plate 19 on the stacking jig 22B.

  Therefore, an upward reaction force based on the contraction force of the coil springs 156 and 43 is applied to the surface pressure block 181 in contact with the upper surface of the uppermost layer plate 19 at that time on the arm-shaped plate portion 145. It is hung through the cylindrical block 150 of the support unit 47 in a state of being placed on the base unit 27 and the base portion 27 of the stacking jig 22B in a state of being placed on the cylindrical block 150. As a result, each layer plate 19 that is laminated and supported by the layer plate support member 35 on the pedestal portion 27 of the lamination jig 22B is sandwiched between the upper surface of the layer plate support member 35 and the lower surface of the surface pressure block 181. In this state, pressure is applied with a pressing force corresponding to the pulling force (approximately 20 tons) of the pulling rod 152. That is, the state shown in FIG. 24 is obtained. In addition, since the L-shaped bracket 167 moves downward together with the large-diameter portion 154 of the connecting bar 182 as the connecting bar 182 moves downward, at this time, the L-shaped bracket 167 moves toward the locking hole 168. The locking state (shallow locking state) of the locking pin 165 is released. Accordingly, the cylindrical block 150 in the support unit 47 can be freely rotated on the arm-like plate portion 145 by the bearing function of the seal bearing 158 with the ring plate 157 and the vertical axis passing through the axis as the center of rotation. .

  And the welding process by the welding apparatus 25 is performed next to each layer board 19 by which the pressurizing process was made as mentioned above. Specifically, the motor 132 on the base plate 130 is rotationally driven in the reverse direction to move the entire support unit 47 downward. Even at this time, since the air cylinder 171 on the top plate portion 127 on the pressure unit 129 side is in the pneumatic operation free state, each layer plate 19 is laminated while the pressure state by the surface pressure block 181 or the like is maintained. It moves downward with the tool 22B. And while this lamination jig | tool 22B moves downward, the welding torch 203 of the welding apparatus 25 moves forward, and a welding process is given to the to-be-welded part 19b of each layer board 19. FIG. When the welding process is performed on one row of welded portions 19b that are continuous in the vertical direction, the welding process is sequentially performed on each row of welded portions 19b that are continued in the other vertical direction. At that time, the servo motor 177 on the fixed plate 176 in the pressurizing unit 129 is rotated by a fixed angle corresponding to the arrangement angle interval of each welded portion 19b, thereby rotating the entire support unit 47. It is done.

  Then, when the welding process of each layer plate 19 is completed as described above, the downward pulling operation state (that is, the pressurizing state) by the pulling rod 152 is released, and the fixing plate 176 is placed on the fixing plate 176. Servo motor 177 rotates 90 degrees in the opposite direction to release the connection state of connection bar 182 to connection rod 38. Then, the cylinder 195 disposed on the upper disk 179 in the pressurizing unit 129 contracts the cylinder rod 196. Then, when the annular plate 188 on the upper disc 179 rotates, the hook bar 187 moves radially inward by the guide action of the skew guide hole 191, the wide guide hole 185, and the narrow guide hole 186, The hook portion 187 c at the lower end engages with the hook hole 37 of the layer plate support member 35. In this state, when the motor 132 on the base plate 130 is rotationally driven in the reverse direction to move the entire support unit 47 downward, the lower disk 180 or the like on the pressure unit 129 side also hooks the hook bar 187. Since the portion 187c and the hooking hole 37 of the layer plate support member 35 are locked, the downward movement together with the support unit 47 is started.

  However, since the locking protrusion 183 of the lower disk 180 comes into contact with the stopper piece 184 protruding from the vertical plate portion 126 or the like in the middle, the support unit 47 and the stack on the support unit 47 will be referred to thereafter. Only the jig 22B moves downward in the vertical direction. Accordingly, the layer plate support member 35 held and held by the hook bar 187 slides upward along the cylindrical portion 28 of the stacking jig 22B in a state where the layered plates 19 that have been welded are stacked and supported. To do. Then, when the layer plate support member 35 moves (slids) to the vicinity of the upper end portion of the cylindrical portion 28 of the stacking jig 22B, the rotational drive of the motor 132 is temporarily stopped. The cylinder 195 then extends the cylinder rod 196. Accordingly, this time, the hook bar 187 slides outward in the radial direction, and the locked holding state with respect to the layer plate support member 35 is released. Then, the motor 132 is rotated again in the reverse direction, and the support unit 47 resumes the downward movement. As a result, the stacking jig 22B on the support unit 47 returns to the initial position P1 on the rail 20B again, and at this position, each layer plate 19 integrated as a motor stack core is recovered from the layer plate support member 35. It is processed.

  As described above, in the laminated work pressure device 24, the support unit 47 and the pressure unit 129 are configured to be relatively movable along the lamination direction of the layer plates 19 laminated on the lamination jig 22B. The support unit 47 is moved up based on the driving force of the motor 132. The pulling rod 152 on the support unit 47 side is connected to the connecting bar 182 on the pressurizing unit 129 side via the connecting rod 38 in the stacking jig 22B. The surface pressure block 181 reliably pressurizes each layer plate 19 on the lamination jig 22B.

According to this embodiment, the following effects can be obtained.
(1) While the moving unit 46 is moving downward in the vertical direction, which is a specific direction, the cam roller 85 is cam-engaged with the cam mechanism 124 of the fixed unit 117, so that the shaft 81 is in a predetermined direction. The rotary table 70 that supports the stacking jig 22B can be horizontally rotated by a fixed angle in a fixed direction. That is, the layer plates 19 stacked on the stacking jig 22B can be stacked (so-called “rolling”) in a state in which the phases are changed by a predetermined number. Moreover, as the device configuration of the drive source for rolling the layer plates 19 in this way, a motor 56 for moving the moving unit 46 up and down can also be used. Therefore, an apparatus configuration for stacking the plate-like layer boards (workpieces) 19 in a state in which the phases are different for every predetermined number can be realized by suppressing the increase in apparatus cost and downsizing the entire apparatus.

  (2) The cam mechanism portion 124, which is mechanically complicated and large in size when the cam roller 85 and the cam mechanism portion 124 that are engaged with each other in cam engagement, are provided in the fixed unit 117, while the mechanism is simple and small in size. Since the cam roller 85 is attached to the shaft 81 on the moving unit 46 side, the overall device configuration can be easily made compact.

  (3) Engagement guide in the direction in which the cam roller 85 is skewed by the skew guide portions 119a and 119c provided in the cam mechanism portion 124 together with the shaft 81 while the moving unit 46 is moving in the vertical downward direction as a specific direction. Therefore, when moving in the oblique direction, it is possible to perform a displacement operation in the horizontal direction. Accordingly, it is possible to easily generate a driving force for rotating the rotary table 70 provided so as to be horizontally rotatable around the vertical axis as a center of rotation based on the displacement operation in the horizontal direction.

  (4) When the cam unit 85 is engaged with the cam mechanism 124 while the moving unit 46 is moving up and down, the cam roller 85 is engaged and guided by the swing member 122 functioning as a guide switching unit. Or a direction along the bypass guide portion 119. At that time, when the moving unit 46 moves up and down in the vertical downward direction as a specific direction, the cam roller 85 is moved along the bypass guide portion 119 having the skew guide portions 119a and 119c by the swing member 122. Guided. Accordingly, the transposition of the layer plate 19 can be realized with certainty.

  (5) In addition, the guide switching portion always closes the vertical guide portion 118 in the vicinity of the upper joining position 120 of the vertical guide portion 118 and the bypass guide portion 119 in the cam mechanism portion 124 so that the cam roller 85 is connected to the bypass guide portion 119. Since the swinging member 122 is biased and held in a posture mode of engaging and guiding in the direction, the guide switching portion can be easily configured.

  (6) The rotation table 70 supported by the moving unit 46 is restricted in rotation when the rotation lock member 99 is engaged with the lock portion 105 integrated with the rotation table 70. The rotation restricted state is locked when the shaft 81 is displaced by moving up and down in the vertical downward direction, which is a specific direction of the moving unit 46, and the cam roller 85 is engaged with the cam mechanism 124. The rotation lock member 99 is detached from the portion 105 and is allowed to rotate. Accordingly, the rotary table 70 can be allowed to rotate only when necessary to roll the layer plate 19, and in other cases, the rotary table 70 supporting the stacking jig 22B rotates unnecessarily. Can be prevented.

  (7) The lock portions 105 are formed on the peripheral surface of the large-diameter cylindrical portion 102 in the stepped cylindrical member 104 that rotates integrally with the rotary table 70 at a plurality of locations corresponding to the rolling angle (in this embodiment, every 120 degrees). And is urged to contact the outer peripheral surface of the large-diameter cylindrical portion 102. Therefore, when the rotary table 70 is rotated by an angle corresponding to the rolling angle, the lock member 99 can be reliably locked to the lock portion 105.

  (8) A taper plate configured to be movable together with the driving body 59 when the moving body 46B that constitutes the moving unit 46 together with the driving body 59 in the jig lifting device 23B moves upward to the stacking position P4 that is a predetermined position. The cam 61 is configured to push the slider 73 functioning as a positioning lock member to a movement restricting position where the slider is engaged with the moving body 46B to restrict the movement. That is, the movable body 46B that supports the stacking jig 22B can be positioned and held in a state where movement is restricted at a predetermined position (stacking position P4). In addition, as the device configuration of the drive source for positioning and holding (locking) the moving body 46B as described above, the motor 56 for moving the moving unit 46 up and down can also be used. Therefore, the movable body 46B provided so as to be movable in a predetermined direction can be securely locked and unlocked as necessary at a predetermined position in the moving direction while suppressing an increase in apparatus cost and downsizing the entire apparatus. Can do.

  (9) The slider 73, which is displaced from the movement allowable position with respect to the moving body 46B to the movement restricting position when pushed by the taper plate cam 61, is always driven by the tension spring 76 when not receiving the pushing force by the taper plate cam 61. It is biased toward the movement allowable position. Therefore, the slider 73 can be displaced to the movement restricting position only when the moving body 46B has moved to the predetermined position (stacking position P4) together with the driving body 59.

  (10) The taper plate cam 61 has a tip surface (upper end surface) 61a that is attached to the slider 73 and abuts and engages with an engagement roller 74 that constitutes a part of the positioning lock member, and is formed in a slope shape. The leading end surface 61a gradually pushes the engagement roller 74 so that the slider 73 is abutted and guided in the direction of the movement restricting position. Accordingly, the slider 73 can be smoothly guided in the direction of the movement restriction position by the tapered plate cam 61 integrated with the drive body 59 as the drive body 59 moves upward.

  (11) On the moving body 46B side, which is positioned and locked at the stacking position (predetermined position) P4, the tip of the slider 73 is placed on the lift plate 62, which is a component of the moving body 46B and is located on the moving path of the slider 73. A locking hole 77 to be inserted and locked is formed. Therefore, the movable body 46B can be reliably positioned and locked by inserting and locking the slider 73 in the locking hole 77.

  (12) When the moving body 46B moves to the stacking position (predetermined position) P4 as the moving unit 46 moves up, the protrusion 31 of the stacking jig 22B that is a moving object that has moved integrally with the moving body 46B By fitting into the stopper hole 32 of the base plate 12, further upward movement is restricted. Therefore, the movable body 46B can be reliably stopped at the stacking position P4 before the movable body 46B is positioned and locked at the stacking position (predetermined position) P4.

  (13) When the moving unit 46 moves upward toward the stacking position (predetermined position) P4, the driving body 59 is driven by the biasing force of the coil spring 66 within the vertical length range (constant range) of the longitudinal groove 63. The moving body 46B follows the moving body 46B and moves to the same height position with a delay after the moving body 46B stops at the stacking position P4. In other words, the drive body 59 is configured to move up by moving the moving body 46B in a floating state based on the urging force of the coil spring 66. Therefore, even when the stacking jig 22B on the moving body 46B fits the protrusion 31 into the stopper hole 32 of the base plate 12, the impact force at the time of fitting is satisfactorily reduced by the contracting action of the coil spring 66. be able to.

  (14) When the mutual positions of a plurality of (two in the present embodiment) stacking jigs (conveyance bodies) 22B are exchanged on the linearly extending rail 20B, one stacking jig 22B is replaced by the slide member 50. The other stacking jig 22B is retracted and moved to the retracted position (in the present embodiment, the stacking position P4) removed from the rail 20B. Therefore, in the conveyance path configuration in which the work position P3 is set between the initial position P1 and the standby position P2 on one rail 20B, the stacking jig 22B is placed on the rail 20B from the initial position P1 to the standby position P2. → Even when transported from the work position P3 to the initial position P1, the respective stacking jigs 22B are transported while smoothly exchanging positions on the rail 20B without interfering with each other. Moreover, in such a system that conveys the stacking jig (conveyance body) 22B while smoothly exchanging the positions, a pair of slide members 50 that reciprocate along the straight bar 48B may be used as a conveyance drive mechanism. Accordingly, while reducing the space between the positions of the plurality of stacking jigs (conveyance bodies) 22B provided on the rail 20B so as to be reciprocally movable along the linear rail (conveyance path) 20B, the cost can be reduced. It can be exchanged with a simple configuration that does not take.

  (15) When the stacking jig 22B at the initial position P1 on the rail 20B is transported to the standby position P2 beyond the work position P3 where the other stacking jig 22B is present, the stacking jig at the work position P3 is used. The tool 22B is retracted to the upper stacking position (retracted position) P4 that is out of the rail 20B. Accordingly, even when a plurality of work positions P3 are set on the rail 20B between the initial position P1 and the standby position P2, the initial position can be obtained by retracting and moving the stacking jigs 22B at the work positions P3. One stacking jig 22B can be reliably conveyed from P1 to the standby position P2.

  (16) When there is another stacking jig 22B at the work position P3, when transferring one stacking jig 22B from the standby position P2 adjacent to the work position P3 to the work position P3, The other stacking jig 22B is pushed in the direction of the initial position P1 by the one stacking jig 22B transported to the position P3. For this reason, a separate transport mechanism is not required to move the other stacking jig 22B at the work position P3 from the work position P3, so that the entire apparatus cost of the transport body position exchanging system 21B increases. There is nothing.

  (17) In the case of the present embodiment, the transport body retracting mechanism for retracting and moving the stacking jig 22B at the work position P3 supports the stacking jig 22B and between the lower position of the rail 20B and the stacking position P4. The moving unit 46 of the jig lifting device 23B that moves up and down is also used. Therefore, a new mechanism is not required separately as a member configuration that constitutes the transport body retracting mechanism, so that an increase in apparatus cost of the entire transport body position exchanging system 21B can also be suppressed in this respect.

  (18) The sliding member 50 that reciprocates along the straight bar 48B parallel to the rail 20B has a locking claw (fixed locking claw 51 and movable locking claw 51) on the locking plate 33 that is a part of the stacking jig 22B. 52) is provided, the slide member 50 can reliably hold and transport the stacking jig 22B by the locking action of these locking claws.

  (19) When the slide member 50 approaches the locking plate 33 of the stacking jig 22B from the direction of the standby position P2, the locking plate is moved after the movable locking claw 52 comes into contact with the locking plate 33. By performing a displacement operation so as to get over 33, the locking plate 33 is held and held between the fixed locking claw 51 and the movable locking claw 52. Accordingly, the stacking jig 22B stopped on the rail 20B can be easily latched and held by the slide member 50 approaching free from the direction of the standby position P2, and the fixed latching claw 51 is formed after the latching and holding state is formed. However, the stacking jig 22B can be reliably transported in the direction of the initial position P1 by pushing the standby position P2 side of the locking plate 33.

  (20) When the movable locking claw 52 comes into contact with the locking plate 33 from the standby position P2 side, the movable locking claw 52 is moved from the standby position P2 side of the locking plate 33 to the initial position P1 side. Since the copying guide portion 33a formed in the profile that is displaced while being combined is provided, the displacement operation of the movable locking claw 52 can be realized smoothly.

  (21) When pressing each layer plate 19 stacked on the stacking jig 22B, first, when the positional relationship between the support unit 47 supporting the stacking jig 22B and the pressing unit 129 is close to each other. Further, a pull-in rod (first connection mechanism) 152 on the support unit 47 side is connected to a connection bar (second connection mechanism) 182 on the pressure unit 129 side by a driving force of a servo motor (second drive mechanism) 177. Actuated. In this state, the pull-in rod 152 moves in the direction of pulling the pressure unit 129 serving as the other unit toward the support unit 47 serving as one unit based on the driving force of the air cylinder (first drive mechanism) 149. . Then, each layer plate 19 is reliably pressurized with a pressing force corresponding to the pulling force of the pulling rod 152 between the stacking jig 22B on the support unit 47 and the surface pressure block 181 on the pressing unit 129 side. . Therefore, it is possible to pressurize each layer plate (work) 19 placed on the stacking jig 22B in the stacking direction while improving work efficiency.

  (22) Since the relative movement direction of the support unit 47 and the pressurizing unit 129 is along the stacking direction of the layer plates 19, the pressurizing operation in the stacked work pressurizing device 24 can be realized while saving space.

  (23) The servo motor 177 serving as the second drive mechanism is in a position state in which the connection bar 182 serving as the second connection mechanism is connected to the pull-in rod 152 serving as the first connection mechanism or is not connected. Since it can be switched to the position mode, a pressurized state can be created as necessary.

  (24) Since the retracting rod (first coupling mechanism) 152 and the coupling bar (second coupling mechanism) 182 are coupled via the coupling rod (coupling member) 38 provided in the stacking jig 22B, When pressurizing each layer plate 19 on the stacking jig 22B, the pressure applied to the uppermost layer plate 19 by the surface pressure block 181 can be effectively exerted.

The said embodiment can also be changed into another embodiment (another example) as follows.
In the above embodiment, the angle at which the turntable 70 rotates to roll the layer plate 19 does not necessarily have to be 120 degrees, and can be appropriately changed depending on the shape of the layer plate 19.

  In the above embodiment, the swing member 122 that constitutes the guide switching portion does not necessarily have to be biased in an oblique posture so as to close the vertical guide portion 118 by the winding spring 123. You may make it rock | fluctuate so that the engagement guide direction of the cam roller 85 may be switched.

  In the above embodiment, a cylindrical body that rotates integrally with the rotary table 70 is provided on the moving unit 46 side, and a spiral groove cam mechanism is formed on the circumferential surface of the cylindrical body, and on the moving path of the cylindrical body. A cam roller 85 that performs cam engagement operation may be provided in the spiral groove.

  In the above embodiment, the specific direction is the direction in which the moving unit 46 rises, and when the moving unit 46 moves upward, the cam roller 85 and the cam mechanism portion 124 are cam-engaged to move the shaft 81 in the horizontal direction (predetermined The driving force for rotating the rotary table 70 may be generated by performing a displacement operation in the direction (direction).

  In the above-described embodiment, the driving body 59 may not be configured to be assembled with the coil spring 66 interposed between the moving body 46B but may be configured to be integrated with the moving body 46B so as to be movable. .

  In the above embodiment, when the moving body 46B rises to the stacking position P4 due to the lifting of the moving unit 46, a part of the moving body 46B comes into contact with the base plate 12 so that more than the moving body 46B at the stacking position P4. May be stopped when the rise of the is restricted.

  In the above embodiment, when the slider 73 is engaged with the moving body 46B in order to position and lock the moving body 46B stopped at the stacking position P4, it contacts the lower end edge of the moving body 46B (elevating plate 62) from below. The movement may be restricted in an engaged state.

In the above embodiment, the tip end surface 61a of the tapered plate cam 61 that functions as a copying guide portion does not necessarily have to be on a slope, and may be, for example, an arc shape.
In the above embodiment, the taper plate cam 61 functioning as a pushing member does not push the slider 73 via the engaging roller 74 but directly pushes the slider 73 itself or via a link mechanism or the like. It is good also as a structure which pushes indirectly.

In the above embodiment, the slide member 50 may be configured to reciprocate by sliding on the lower end of the rail 20B instead of the straight bar 48B.
In the above embodiment, the work position P3 set between the initial position P1 and the standby position P2 along the rail 20B is not limited to one, and a plurality of positions may be set. In this case, it is possible to increase the number of stacking jigs 22 </ b> B serving as a transport body with an increase in the number of set positions for the work position P <b> 3.

  In the above embodiment, a plurality of connecting rods 38 of the stacking jig 22B serving as a connecting member may be provided on the outer peripheral side instead of the axial center of the stacking jig 22B. In this case, a plurality of pull-in rods 152 on the support unit 47 side and a plurality of connection bars 182 on the pressure unit 129 side are also provided in accordance with the installation location of the connection rod 38.

  In the above embodiment, the support unit 47 may not be moved to the pressure unit 129 side, but the pressure unit 129 may be moved to the support unit 47 side, or the support unit 47 and the pressure unit 129 may be moved. You may comprise so that both can be moved to the direction which approaches and separates mutually.

  In the above embodiment, the first drive mechanism in the laminated work pressure device 24 is not limited to the air cylinder 149 as long as it is a drive mechanism that can move the retracting rod 152 along the lamination direction of the layer plate 19. You may actualize with another drive mechanism.
