Japanese Patent Laid-Open No. 2001-246503 FIG.

  Since the bar supplied by the bar supply machine is inserted into the main shaft of the bar processing machine, the central axis of the bar guided along the guide rail needs to be coaxial with the feed axis. Therefore, when the diameter of the bar to be processed changes, it is necessary to change the setting of the bar feeder. In other words, when the diameter of the bar is changed, the height position of the central axis of the bar when the bar is supplied to the front guide rail and the rear guide rail is shifted from the feed axis of the bar processing machine. It is necessary to change the height dimension so that is on the same axis. Since this work must be performed individually for each guide rail, the work to change the dimensions of the bar feeder becomes complicated, and it takes time to start the next bar work, affecting production efficiency. .

  In addition, as a material shelf on which the bar is placed, for example, there is a structure having a structure inclined obliquely downward toward the guide rail. In the material shelf having such a structure, after the bar closest to the guide rail is supplied to the guide rail, the next bar rolls on the inclined surface and is arranged at the supply position to the guide rail. At this time, the next bar stops by hitting a stopper located at the end of the material shelf. In particular, when the size of the bar is large, the impact caused when the bar hits against the stopper causes noise.

A first object of the present invention is to provide a bar feeder and a bar processing system that can perform a dimensional change operation easily and in a short time.
In addition, a second object of the present invention is to provide a bar feeder and a bar processing system that can alleviate the impact on the bar and suppress the noise of the bar feeder.

  The first object of the present invention is a bar feeder that feeds a bar to a bar processing machine along a feed axis, and is taken out of the material shelf on which the bar is placed, and the material shelf. The guide rail for guiding the bar material along the feed axis, and the bar is arranged parallel to the guide rail upward or downward, and the bar material is fed to the bar processing machine along the feed axis And a moving mechanism that moves the guide rail and the feeding arrow integrally in the vertical direction so that they are alternately positioned on the feeding axis, and a vertical mechanism that adjusts the moving distance of the guide rail and the feeding arrow. It can achieve by the bar feeder provided with a distance adjustment means.

  According to this invention, the guide rail and the feed arrow are alternately positioned on the feed axis by moving the guide rail and the feed arrow integrally in the vertical direction by the moving mechanism. Changing the size of the bar changes the height of the central axis of the bar received in the guide rail. However, according to the present invention, since the feed arrow and the guide rail can move integrally, the vertical distance adjustment means The moving distance in the vertical direction of the moving mechanism is changed by a single adjustment operation, and the central axis of the bar can be made coincident with the feeding axis. Therefore, when changing the size of the bar material, it is only necessary to adjust the moving distance of the moving mechanism by the vertical distance adjusting means, so that the size changing operation of the bar material feeder becomes easy and can be performed in a short time. Become.

In the embodiment of the present invention, the feed arrow is cantilevered at the end far from the bar processing machine, and further provided near the bar processing machine to feed the central axis of the feed arrow It is preferable to have a feed arrow supporting means that is coaxially supported by the axis.
According to this embodiment, since one end of the feed arrow is supported and the other end is supported by the feed arrow support means, the feed arrow moves along the feed axis while being supported by the feed arrow support means. . Since the feed arrow is cantilevered at the end on the side far from the bar processing machine, the support structure of the feed arrow is simplified compared to the conventional structure in which the feed arrow is arranged on the guide rail. Thereby, the number of parts of the bar feeder is reduced, and the manufacturing cost is reduced.

  Further, the second object is that, in another embodiment of the present invention, the bar mounting surface on which the bar of the material shelf is mounted is mounted near the guide rail from the upstream side of the mounting surface far from the guide rail. A stopper member that is inclined downward toward the mounting surface downstream side, further protrudes upward from the bar material mounting surface on the downstream side of the mounting surface, and prevents the bar material from falling from the bar material mounting surface; A push-up member that moves upward from below at the edge on the downstream side of the placement surface of the material shelf and pushes up only one rod on the most downstream side of the placement surface adjacent to the stopper member, and the stopper member from the rod placement surface. A push-up member reciprocating means for reciprocating the push-up member between a first push-up position for pushing up the bar to a height and a retreat position for retreating to a height below the bar placing surface; and the push-up member at the retreat position. In some cases, only the bar on the most downstream side of the mounting surface is positioned on the push-up member A stopper member that reciprocates the stopper member along the material shelf mounting surface between the take-out position and the reception position that approaches and receives the bar to be supplied next when the push-up member is at the first push-up position.

Therefore, when the push-up member is at the first push-up position, the stopper member is at the bar take-out position. When the push-up member is pushed up in this state, one bar is taken out. The bar on the bar mounting surface after the bar is taken out moves to the mounting surface downstream side along the inclined surface, but the stopper member moves to the receiving position by the stopper member reciprocating means. By doing so, the next bar is approached.

The guide rail is positioned in the vicinity of the push-up member. Therefore, the impact when the bar is received in the guide rail is reduced. Thereby, vibration and noise of the bar feeder are suppressed.
Further, since the push-up member reciprocating means is a moving mechanism, and the push-up member reciprocates up and down in synchronization with the vertical movement of the guide rail, when the guide rail moves upward, one bar is taken out by the push-up member.

[First embodiment]
A first embodiment of the present invention will be described below in detail with reference to the drawings.
FIG. 1 shows a front view of a bar feeder 1 according to the first embodiment of the present invention, FIG. 2 shows a plan view of the bar feeder 1, and FIG. 3 shows a side view of the bar feeder 1. Indicates.
First, as shown in FIG. 1, the bar supply machine 1 is disposed adjacent to the bar processing machine 100 and includes the bar supply machine 1 and the bar processing machine 100, and the bar processing system of the present invention. 200 is configured. The bar processing machine 100 is, for example, a spindle-fixed NC lathe, and includes a main shaft base 101 having a main shaft A and a processing unit (not shown) for processing a bar material supported by the main shaft base 101. The bar feeder 1 supplies the bar W to the bar processing machine 100 one by one along the feeding axis B that coincides with the main shaft A.
In addition, since the bar W is supplied toward the bar processing machine 100 in the bar supply machine 1, in this embodiment, in order to simplify the description, the bar supply machine 1 starts from the bar processing machine 100. The far side is referred to as the upstream side, and the side close to the bar processing machine 100 is referred to as the downstream side.

  As shown in FIGS. 1, 2, and 3, the bar feeder 1 includes a support frame 2 extending parallel to the feed axis B, and a bar W supported by the support frame 2 to the feed axis B. A guide rail 10 that is guided along, a feed arrow 40 that feeds the bar W to the bar processing machine 100 along the feed axis B, a moving frame 50 that supports the guide rail 10 and the feed arrow 40, and movement A moving mechanism 60 that moves the guide rail 10 and the feed arrow 40 integrally in the vertical direction by moving the frame 50 in the vertical direction, and a material shelf 70 on which the bar W supplied to the guide rail 10 is placed (see FIG. 2 and FIG. 3) and a controller 80 for controlling the operation of the bar feeder 1.

FIG. 4 shows a partially enlarged view of FIG.
As shown in FIG. 4 and FIGS. 1, 2, and 3 described above, the guide rail 10 extends on the moving frame 50 in parallel with the feed axis B over the longitudinal direction of the bar feeder 1. The guide rail 10 is formed in a V-shaped cross section and can hold the bar W on the inner surface. When the bar W is supplied to the guide rail 10 due to the V-shaped shape of the guide rail 10, the center of the bar W is always positioned at the same position in the width direction regardless of the diameter of the bar W. Further, in the guide rail 10, a buffer pad 10 </ b> A is provided on the side opposite to the side where the material shelf 70 is provided in order to reduce the impact when the bar W is supplied from the material shelf 70. .

The guide rail 10 is provided with a primary feed member 11 for guiding (primary feed) the bar W supplied into the guide rail 10 to the bar processing machine 100 side.
The primary feed member 11 is formed in a block shape and is arranged inside the V-shaped cross section of the guide rail 10. A primary feed member driving device 12 that moves the primary feed member 11 along the longitudinal direction of the guide rail 10 is connected to the primary feed member 11. The primary feed member driving device 12 includes a servo motor 13 (FIG. 1) and an endless chain 14 disposed along a feed axis B on a moving frame 50 below the guide rail 10. The primary feed member 11 passes through a tip portion having a V-shaped cross section, which is the bottom of the guide rail 10, and is connected to the endless chain 14 on the moving frame 50 below the guide rail 10. Such a primary feed member 11 is movable in the guide rail 10 along the longitudinal direction of the guide rail 10 by the operation of the servo motor 13.

The feed arrow 40 is provided on the moving frame 50 and extends parallel to the feed axis B over the longitudinal direction of the bar feeder 1 above the guide rail 10 in the vertical direction. Therefore, the longitudinal axis of the feed arrow 40 and the longitudinal axis of the guide rail 10 are arranged in parallel in the vertical plane.
The feed arrow 40 is cantilevered by the upstream end being fixed to the blade member 41. The downstream end of the feed arrow 40 is supported by rollers 42 as upper and lower feed arrow support means so that the central axis of the feed arrow 40 is coaxial with the feed axis B. The blade member 41 is connected to a feed arrow driving device 43 that moves the feed arrow 40 along the longitudinal direction. The feed arrow driving device 43 includes a servo motor 44 and an endless chain 45 disposed along the feeding axis B, and the blade member 41 is connected to the endless chain 45. Such a feed arrow 40 moves along the feed axis B when the blade member 41 is moved by the operation of the servo motor 44. The downstream end of the feed arrow 40 moves so as to protrude toward the bar processing machine 100 while being supported by the upper and lower rollers 42.

The moving frame 50 is formed in a substantially C-shaped cross section, and the bottom surface 50 </ b> A is supported by the moving mechanism 60. The side surface 50B that stands vertically from the bottom surface 50A is disposed on the side opposite to the side on which the material shelf 70 is provided. The side surface 50 </ b> B supports the endless chain 45 of the feed arrow 40. An upper surface 50C having a width dimension shorter than that of the bottom surface 50A is formed at the upper end of the side surface 50B. A blade member 41 is slidably supported on the lower surface of the upper surface 50C. Further, the roller 42 is supported between a bracket 50D and a side surface 50B provided upright on the bottom surface 50A.
As described above, the guide rail 10, the primary feed member 11, the primary feed member drive device 12, the feed arrow 40, and the feed arrow drive device 43 are connected to the moving frame 50. Therefore, when the moving frame 50 is moved by the moving mechanism 60, the guide rail 10 and the feed arrow 40 move integrally.

The moving mechanism 60 includes an air cylinder 61 that moves the moving frame 50 in the vertical direction, a guide mechanism 62 that guides the movement of the moving frame 50, and a regulating means 63 that regulates the vertical movement distance of the air cylinder 61. .
The air cylinder 61 is fixed to the support frame 2 and provided at a plurality of locations (two locations in the present embodiment, see FIG. 2), and the piston 61 </ b> A is fixed to the bottom surface 50 </ b> A of the moving frame 50.
The guide mechanism 62 includes a plurality of (two in this embodiment, see FIG. 1) slide guides 64 erected from the support frame 2 and a slider 65 provided corresponding to the slide guide 64. The two slide guides 64 are arranged in the vicinity of the air cylinder 61 with a predetermined distance from each other, thereby stably moving the moving frame 50 in the vertical direction. The slider 65 is fixed to the side surface 50 </ b> B of the moving frame 50 and is slidable in the vertical direction along the slide guide 64.
Thus, when the air cylinder 61 is activated, the moving frame 50 moves in the vertical direction while the slider 65 is guided by the slide guide 64. Therefore, the guide rail 10, the feed arrow 40, and the push-up member 51 that are connected to the moving frame 50 also move integrally with the moving frame 50 in the vertical direction.

The restricting means 63 is a bar-like member that is positioned above the slider 65 and is supported by the two slide guides 64 and spanned between them. The lower surface of the restricting means 63 can come into contact with the upper surface of the slider 65, and when the slider 65 comes into contact with the restricting means 63, the moving frame 50, that is, the guide rail 10 and the feed arrow 40 in the vertical direction. The travel distance is regulated.
A vertical distance adjusting means 66 capable of changing the height position of the restricting means 63 is provided substantially at the center in the longitudinal direction of the restricting means 63. The vertical distance adjusting means 66 is composed of a screw that engages with the stopper 63, and the height position of the stopper 63 can be changed by the screwing amount of the vertical distance adjusting means 66. As a result, the vertical movement distance of the moving frame 50, that is, the vertical movement distance between the guide rail 10 and the feed arrow is adjusted.

  Here, in a state where the piston 61A is housed in the air cylinder 61 and the air cylinder 61 does not operate, the moving frame 50 is disposed at the lower position which is the initial position, and at this lower position, the central axis of the feed arrow 40 is It coincides with the feeding axis B. Further, in a state where the upper surface of the slider 65 is in contact with the lower surface of the restricting means 63, the moving frame 50 is disposed at the upper position. The height of the restricting means 63 is set so that the central axis of the bar W supplied to the guide rail 10 coincides with the feeding axis B at this upper position.

As shown in FIGS. 2 and 4, the material shelf 70 includes a plurality (five in this embodiment) of material shelf frames 71 arranged in a direction orthogonal to the feeding axis B, and the material shelf 70 to the bar material. A bar replenishing mechanism 300 for taking out one W and replenishing it to the guide rail 10 is provided.
Each material shelf frame 71 is fixed to the support frame 2 at the end on the guide rail 10 side. The opposite end of each material shelf frame 71 is connected to a support member 74 that extends parallel to the feeding axis B, and the support member 74 is supported by two support rods 75, whereby the material shelf frame 71. The whole is supported. The material shelf frame 71 is inclined obliquely downward from the upstream side of the mounting surface far from the guide rail 10 toward the downstream side of the mounting surface close to the guide rail 10, thereby tilting the bar mounting surface inclined to the upper surface. 71A is formed.

  The bar replenishing mechanism 300 includes a stopper member 72 that prevents the bar W from dropping from the bar mounting surface 71A on the downstream side of the mounting surface of the material shelf 70, and the stopper member 72 that is mounted on the bar of the material shelf 70. A stopper member reciprocating means 73 that reciprocates along the placement surface 71A, and a bar W that is fixed to the moving frame 50, moves upward from below and is adjacent to the stopper member 72 and is most downstream on the placement surface. And a push-up member 51 that pushes up only.

  The stopper member 72 is provided on the side surface of each material shelf frame 71, and protrudes downward from the longitudinal center of the slide portion 72A and the slide portion 72A disposed along the bar placement surface 71A of the material shelf frame 71. It has a protruding portion 72B and is formed in a substantially T shape as a whole. Two long holes 72C are formed in the slide portion 72A along the longitudinal direction, and the protrusions 71B protruding from the material shelf frame 71 are disposed in the long holes 72C. It is provided so as to be slidable along the hole 72 </ b> C, that is, along the bar placement surface 71 </ b> A of the material shelf frame 71.

On the downstream side of the mounting surface near the guide rail 10 in the slide portion 72A, a hook-shaped holding portion 72D that protrudes upward from the bar mounting surface 71A is formed. The holding part 72D protrudes substantially perpendicular to the bar placing surface 71A, and the bar W placed on the material shelf 71 by the holding part 72D is prevented from rolling on the bar placing surface 71A. Is done.
Each protrusion 72B of the stopper member 72 provided on each material shelf frame 71 is connected by a connecting rod 76 below the material shelf frame 71. Thereby, when the connecting rod 76 moves, the plurality of stopper members 72 move integrally in synchronization.

The stopper member reciprocating means 73 includes a motor 77 and an arm 78 fixed to the output shaft 77 </ b> A of the motor 77. The motor 77 is arranged on the upstream side of the material shelf 70, the output shaft 77A extends in parallel to the feeding axis B from the upstream side to the lower side of the third material shelf frame 71, and the end portion is the fourth. The material shelf frame 71 is rotatably supported.
A plurality of arms 78 (two in this embodiment) are provided on the output shaft 77A, and one end of these arms 78 is fixed to the output shaft 77A. A long hole 78A is formed at the other end of the arm 78, and the connecting rod 76 passes through the long hole 78A.

According to such a stopper member reciprocating means 73, when the motor 77 rotates by a predetermined angle, the output shaft 77A rotates and the arm 78 rotates. As the arm 78 rotates, the connecting rod 76 moves to the downstream side of the placement surface. By movement of the connecting rod 76, all the stopper members 72 move along the long holes 72C in the direction approaching and separating from the guide rail 10 (downstream side of the placement surface).
The reciprocating distance of the stopper member 72 is determined by the rotation angle of the motor 77. For this reason, the motor 77 is provided with an encoder 77B for detecting the rotation angle.

  The push-up member 51 is provided so as to protrude in a direction orthogonal to the longitudinal direction of the guide rail 10 from the side of the bottom surface 50 </ b> A facing the material shelf 70 toward the material shelf 70. A plurality of push-up members 51 are provided along the longitudinal direction of the guide rail 10 (six locations in the present embodiment, see FIG. 2). Here, the distance between the push-up members 51 becomes smaller toward the downstream side, so that even a bar W having a small length can be handled.

  The push-up member 51 is a trapezoidal plate-like member whose plane is arranged in the vertical direction, and its upper end surface is inclined obliquely downward from the placement surface upstream side of the guide rail 10 toward the placement surface downstream side. This is a bar push-up surface 51A for pushing up. The bar pushing surface 51A is continuous with the edge of the guide rail 10. Therefore, when the guide rail 10 and the lifting member 51 are viewed from the side, the bar pushing surface 51A and the inner surface of the guide rail 10 are continuous. ing. Here, the inclination angle of the bar pressing surface 51A is set to be smaller than the inclination angle of the inner surface of the guide rail 10, and the bar W causes an excessive impact on the guide rail 10 due to the inclination angle of the bar pressing surface 51A. The speed at which the bar W rolls on the bar pressing surface 51A is adjusted so as not to give it.

In the push-up member 51, the side end surface opposite to the side fixed to the bottom surface 50 </ b> A is formed along the vertical direction. As a result, the push-up member 51 moves upward together with the moving frame 50. In this case, the bar W placed on the material shelf 70 is prevented from rolling and moving to the guide rail 10 side.
Since the push-up member 51 is fixed to the moving frame 50, when the moving frame 50 is moved by the moving mechanism 60, it moves integrally with the moving frame 50. Accordingly, in the present embodiment, the moving mechanism 60 also serves as the push-up member reciprocating means of the present invention that moves the push-up member 51 up and down.

Here, at the lower position of the moving frame 50, the bar pushing surface 51A of the push-up member 51 is not higher than the bar placing surface 71A, and the bar pushing surface 51A does not protrude from the bar placing surface 71A. , Arranged at the retracted position. Further, at the upper position of the moving frame 50, the bar pushing surface 51A of the push-up member 51 is higher than the upper end of the holding portion 72D of the stopper member 72, and the bar pushing surface 51A protrudes from the bar placing surface 71A. It arrange | positions in a 1st raising position.
Further, when the stopper member 72 moves to the downstream side of the placement surface, the stopper member 72 has a position of the holding portion 72D having a distance equal to or larger than the radius of the bar W from the stop portion 51B which is the end portion of the push-up member 51. It is set to be a position. That is, when the push-up member 51 moves upward and is arranged at the first push-up position, the holding member 72D is positioned so that the bar W on the most downstream side adjacent to the holding unit 72D is stable. It arrange | positions so that the bar W may be arrange | positioned in the position which gets on the raising member 51. FIG. Accordingly, the position of the holding portion 72D is arranged on the guide rail side for a predetermined distance with the position of the stopping portion 51B as a reference position. This position is the bar material take-out position of the stopper member 72 when the push-up member 51 takes out only one bar W. Then, the receiving position where the stopper member 72 moves to the upstream side of the placement surface and approaches the bar W to be supplied next to receive the bar W is such that the position of the holding part 72D coincides with the stop part 51B. Is set to

The controller 80 controls the operation of the bar feeder 1. Specifically, the controller 80 is connected to the primary feed member driving device 12, the feed arrow driving device 43, the moving mechanism 60, and the stopper member reciprocating means 73, and controls these operations.
The controller 80 stores the bar material extraction position and the reception position of the stopper member 72 corresponding to the type (diameter dimension) of the bar material in the form of a table, an arithmetic expression, or the like. Actually, since the bar material take-out position and the reception position are adjusted by rotating the motor 77, these bar material take-out position and reception position are the rotation position (rotation angle) of the motor 77. Is remembered as
The controller 80 is also connected to the bar processing machine 100 and inputs a bar supply signal for requesting the supply of the bar W from the bar processing machine 100.

Next, the operation of the bar processing system 200 will be described.
First, in the initial state in FIG. 4 described above, the air cylinder 61 is not operated, and the moving frame 50 is disposed at the lower position. In this state, the longitudinal axis of the feed arrow 40 coincides with the feed axis B. Further, the push-up member 51 is disposed at a retracted position that does not protrude from the bar placement surface 71A of the material shelf frame 71. And the stopper member 72 is arrange | positioned from the restraining part 51B of the push-up member 51 in the bar extraction position on the guide rail 10 side more than the radius of the bar W.

In such an initial state, when the controller 80 inputs a bar supply signal from the bar processing machine 100, the controller 80 outputs an upward movement signal to the air cylinder 61. The air cylinder 61 is actuated by this upward movement signal, and moves the piston 61A upward as shown in FIG.
When the moving frame 50 moves upward due to the movement of the piston 61A, the guide rail 10 and the feed arrow 40 move integrally upward. At this time, the push-up member 51 fixed to the moving frame 50 also moves to the upper first push-up position. As the push-up member 51 moves upward, the bar pushing surface 51A protrudes from the bar placing surface 71A of the material shelf frame 71, and the bar W placed on the bar pushing surface 51A is moved upward by one. Push up. When the bar W is pushed upward from the upper end of the holding portion 72D, the bar W rolls toward the guide rail 10 along the bar pressing surface 51A and is supplied into the guide rail 10.

After the bar W closest to the mounting surface adjacent to the holding portion 72D is supplied to the guide rail 10, the bar W to be supplied next placed on the material shelf 70 is placed on the bar. Although it moves to the guide rail 10 side along the surface 71 </ b> A, further movement is restrained by the restraining portion 51 </ b> B of the push-up member 51.
The upward movement of the moving frame 50 is restricted by the restricting means 63. That is, when the moving frame 50 moves, the upper surface of the slider 65 comes into contact with the lower surface of the regulating means 63, the moving frame 50 stops, and the moving frame 50 is positioned at the upper position.
When the moving frame 50 is stopped at the upper position, the central axis of the bar W supplied into the guide rail 10 coincides with the feeding axis B.

Next, as shown in FIG. 6, the bar W in the guide rail 10 is primarily fed to the bar processing machine 100 side.
When the moving frame 50 is disposed at the upper position, the controller 80 outputs a primary feed signal to the primary feed member driving device 12. The primary feed member driving device 12 inputs this signal and operates the servo motor 13. When the endless chain 14 moves due to the rotation of the servo motor 13, the primary feed member 11 moves from the upstream side to the downstream side along the guide rail 10. The end portion of the primary feed member 11 is brought into contact with the end portion of the bar W in the guide rail 10, and the bar W is pushed downstream, whereby the primary feed is performed.

  Further, the controller 80 outputs a stopper member reception signal to the stopper member reciprocating means 73 simultaneously with the output of the primary feed signal or during the primary feed. The stopper member reciprocating means 73 inputs this signal and rotates the motor 77 by a predetermined angle. With the rotation of the motor 77, the arm 78 is rotated, and the stopper member 72 is retracted a predetermined distance upstream of the placement surface and moved to the reception position. In a state where the stopper member 72 is disposed at the reception position, the holding portion 72D coincides with the position of the stopping portion 51B. As a result, the bar W to be supplied next placed on the material shelf 70 is stopped by the stopping portion 51B and received by the holding portion 72D. Note that the predetermined rotation angle of the motor 77 is set in advance by a bar material take-out position and an acceptance position that are determined according to the diameter of the bar W.

Next, as shown in FIG. 7, the moving frame 50 is moved downward so that the feed arrow 40 coincides with the feed axis B.
When the primary feed is finished and the stopper member 72 moves to the reception position, the controller 80 outputs a downward movement signal to the movement mechanism 60. The air cylinder 61 inputs this signal, moves the piston 61A downward, and moves the moving frame 50 downward. Thereby, the moving frame 50 returns to the lower position. That is, in this state, the center axis of the feed arrow 40 coincides with the feed axis B.
At this time, as the moving frame 50 moves, the push-up member 51 also moves to the retracted position. However, since the holding portion 72D of the stopper member 72 is at the receiving position, it should be supplied next downstream of the placement surface. The bar W is held by the holding portion 72D. Therefore, the bar W is prevented from rolling along the bar mounting surface 71A of the material shelf 70.

Next, as shown in FIG. 8, the bar W is fed to the bar processing machine 100.
The controller 80 outputs a feed signal to the feed arrow driving device 43. The servo motor 44 receives this signal and rotates at a predetermined speed. The endless chain 45 moves in accordance with the rotation of the servo motor 44, and the feed arrow 40 moves downstream with the blade member 12 fixed to the endless chain 45. The downstream end of the feed arrow 40 protrudes to the bar processing machine 100 side on the feed axis B while being supported by the roller 42, and pushes the end of the bar W to thereby remove the bar W from the bar Feed to the processing machine 100.

Further, the controller 80 outputs an origin return signal of the primary feed member 11 to the primary feed member driving device 12 during feeding of the bar W by the feed arrow 40. The primary feed member driving device 12 rotates the servo motor 13 to return the primary feed member 11 to the upstream side.
Further, the controller 80 outputs a stopper member initial position signal to the stopper member reciprocating means 73. The stopper member reciprocating means 73 rotates the motor 77 by a predetermined angle to move the stopper member 72 downstream of the placement surface to the bar material extraction position. At this time, since the material shelf 70 has the inclined bar mounting surface 71A, the bar W moves to the bar take-out position as the stopper member 72 moves.
By the above operation, the bar feeder 1 returns to the initial state of FIG. By repeating the above operation, the bar W is supplied to the bar processing machine 100 one by one.

Next, the dimension setting procedure of the bar feeder 1 when changing the dimensions of the bar to be processed will be described.
When the bar material processed by the bar material processing machine 100 is changed and the diameter dimension of the bar material W is changed, the dimension setting of the bar material supply machine 1 needs to be changed. For example, when the diameter of the bar W is reduced, when the bar W is supplied to the guide rail 10, the central axis of the bar W in the guide rail 10 becomes lower than before. Therefore, the vertical position adjusting means 66 is operated to adjust the height position of the restricting means 63 so that the center axis of the bar W coincides with the feeding axis B when the guide rail 10 is in the upper position. .

  Moreover, since the diameter dimension of the bar W changes, it is necessary to set the bar material take-out position and the reception position of the stopper member 72. In the present embodiment, the controller 80 stores in advance the bar material extraction position and the reception position of the stopper member 72 corresponding to the diameter of the bar material W. Therefore, when the diameter of the bar W (or the type of bar to be processed) is input to the controller 80, the controller 80 determines the bar take-out position and the reception position corresponding to the diameter of the bar W, and the motor 77 is driven to move the stopper member 72 to a predetermined bar takeout position, and the setting of the bar takeout position and the receiving position is automatically changed. At this time, the bar removal position is defined as a position moved to the guide rail side by a predetermined distance with the position of the stop portion 51B as a reference position.

According to the bar processing system 200 as described above, the following effects can be obtained.
Since the guide rail 10 and the feed arrow 40 are arranged in parallel in the vertical direction and moved up and down integrally by the moving mechanism 60, the vertical distance adjusting means 66 is operated when changing the diameter of the bar W. Then, the dimension setting of the guide rail 10 and the feed arrow 40 is completed only by adjusting the height position of the regulating means 63, so that the dimension changing operation can be easily performed and the dimension changing time can be shortened.
Further, since the feed arrow 40 is arranged on the upper side in the vertical direction of the guide rail 10 and the central axis of the feed arrow 40 coincides with the feed axis B at the lower position of the moving frame 50, the diameter of the bar W is changed. However, there is no need to change the lower position. Accordingly, since the setting of the upper position only needs to be changed by the restricting means 63, the dimension changing operation can be easily performed with a simple structure.

  Since the moving mechanism 60 includes the air cylinder 61, the slider 65, and the restricting means 63, the lower position and the upper position of the moving frame 50 are defined only by turning on / off the air cylinder 61. Therefore, the structure and control of the moving mechanism can be simplified. Further, the guide rail 10 and the feed arrow 40 can be more accurately positioned by the moving mechanism 60 including the air cylinder 61 and the restricting means 63.

  The bar replenishing mechanism 300 includes the push-up member 51, the stopper member 72, and the stopper member reciprocating means 73, and reciprocates the stopper member 72 between the bar extracting position and the receiving position. The bar W on the placement surface 71A can be received by the stopper member 72. Therefore, it can be prevented that the bar W rolls on the bar mounting surface 71A and hits the material shelf 70 to receive an impact. Thereby, damage to the bar W can be prevented, and vibration of the bar feeder 1 due to impact can be prevented, so that noise of the bar feeder 1 can be minimized. Moreover, since the noise of the bar feeder 1 is suppressed, the speed of the bar feeder 1 can be increased. Furthermore, since the noise of the bar feeder 1 is suppressed, a large bar can be handled with low noise, so that the size range of the bar that can be handled by the bar feeder 1 can be made wider. it can.

Since the push-up member 51 is fixed to the moving frame 50 and moves integrally with the guide rail 10 by the moving mechanism 60, the push-up member 51 supplies the bar W to the guide rail 10 at the same time as the guide rail 10 moves upward. To do. Therefore, since the movement of the guide rail 10 and the supply of the bar W are performed simultaneously, the bar supply time can be shortened.
Furthermore, since the moving mechanism 60 also serves as the upper and lower drive mechanisms of the push-up member 51, the drive mechanism for the push-up member 51 can be omitted, so the configuration of the bar replenishing mechanism 300 can be simplified and the number of parts can be reduced. The manufacturing cost can be reduced.

  Since the feed arrow 40 is cantilevered by the blade member 41 and the downstream end is supported by the roller 42, it is compared with the structure in which the feed arrow 40 is conventionally arranged and supported in the guide rail. Thus, the support mechanism for the feed arrow 40 can be simplified. Thereby, the number of parts of the support mechanism of the feed arrow 40 can be reduced, and manufacturing cost can be reduced.

  Since the controller 80 determines the bar material take-out position and the receiving position of the stopper member 72 according to the diameter dimension of the bar material W, when changing the bar material W to be processed, the diameter dimension of the bar material W is changed. By inputting to the controller 80, the dimension setting of the stopper member 72 can be automatically adjusted. Therefore, the dimension changing operation can be simplified.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. The bar feeder 90 according to the second embodiment differs from the bar feeder 1 of the first embodiment in the operations of the stop member, the push-up member, and the guide rail.
FIG. 9 is a schematic view showing an initial state of the bar feeder 90 according to the second embodiment of the present invention. As shown in FIG. 9, the push-up member 92 of the bar feeder 90 is configured to move integrally with the guide rail 94, as in the first embodiment. The push-up member 92 and the guide rail 94 reciprocate up and down by a moving mechanism. Therefore, also in this embodiment, the moving mechanism also serves as the push-up member reciprocating means of the present invention.
The moving mechanism is configured to include a servo motor and can stop the push-up member 92 and the guide rail 94 at an arbitrary position. The operation of the servo motor is controlled by the controller 80. In the present embodiment, the push-up member 92 and the guide rail 94 include a retreat position where the bar push-up surface 92A of the push-up member 92 does not protrude from the bar placing surface 71A, and the bar push-up surface 92A from the bar placing surface 71A. A second push-up position where the bar W protrudes by a predetermined dimension and pushes up only one bar W, and the bar W does not get over the upper end of the holding portion 96A of the stopper member 96, and a bar placed on the guide rail 94 The center axis of the material W reciprocates between the feed position, which is a position that coincides with the feed axis. Therefore, the second push-up position is arranged at a position between the bar mounting surface 71A and the height of the holding portion 96A of the stopper member 96. The retracted position, the second push-up position, and the delivery position are determined by the controller 80 according to the input of the diameter of the bar W.

  As in the first embodiment, the stopper member reciprocating means of the stopper member 96 includes a motor, and is configured such that the stopper member 96 approaches and separates from the guide rail 94 according to the rotation angle of the motor. Here, the stopper member 96 includes a bar take-out position where the most downstream bar W on the bar placing surface 71A is positioned on the push-up member 92, and the bar W pushed up by the push-up member 92. It reciprocates between a bar guide position positioned above the mounting position of the guide rail 94 and a reception position for receiving the bar W to be supplied next. In the present embodiment, the bar material extraction position and the reception position are set in the same manner as in the first embodiment. Further, the bar guide position is such that the central axis of the bar W held by the holding portion 96 </ b> A of the stopper member 96 is above the center axis of the bar W placed in the guide rail 94 in the vertical direction. Is set. The bar removal position, bar guide position, and reception position are determined by the controller 80 in accordance with the input of the diameter of the bar W.

Next, the operation of the bar feeder 90 according to the second embodiment will be described.
First, as shown in FIG. 9, at the initial position of the bar feeder 90, the guide rail 94 and the push-up member 92 are positioned below so that the push-up member 92 is in the retracted position. On the other hand, the stopper member 96 is in the reception position, and holds the bar W by the holding portion 96A.

10 to 14 are schematic views showing the operation of the bar feeder 90 according to the second embodiment of the present invention.
As shown in FIG. 10, when the stopper member 96 is moved from the receiving position to the bar take-out position by the stopper member moving means, the bar W on the bar placing surface 71A is moved along with the movement of the holding portion 96A. Then, it moves in the direction approaching the guide rail 94. In the state in which the stopper member 96 is in the bar removal position, only one of the bar W on the most downstream side of the bar mounting surface 71A is positioned on the bar pushing surface 92A of the push-up member 92.

  Next, as shown in FIG. 11, the guide rail 94 and the push-up member 92 are moved upward by the moving mechanism. By this movement, the push-up member 92 is disposed at the second push-up position. At this time, one bar W arranged on the push-up member 92 is pushed up by the push-up member 92. However, in the second push-up position, the bar W does not get over the holding part 96A, and the holding part 96A.

As shown in FIG. 12, the stopper member 96 is moved to the bar guide position by the stopper member reciprocating means. By this movement, the bar W is guided above the guide rail 94 while being held by the holding portion 96A. At this time, since the push-up member 92 is in the second push-up position, the restraining portion 92B prevents the movement of the bar W to be supplied next.
Then, as shown in FIG. 13, the guide rail 94 and the push-up member 92 are moved upward to the delivery position by the moving mechanism. By this movement, the guide rail 94 receives the bar W on the stopper member 96 from below and moves the bar W upward. At the delivery position, the central axis of the bar W coincides with the feed axis of the bar processing machine. In this state, the bar W is primarily fed to the bar processing machine side by a primary feed member (not shown).

During the primary feed, the stopper member 96 is moved from the bar guide position to the reception position by the stopper member reciprocating means as shown in FIG. By this movement, the holding portion 96A coincides with the restraining portion 92B, and the bar W to be supplied next is held by the holding portion 96A.
When the primary feed of the bar W is completed, the moving mechanism moves the guide rail 94 and the push-up member 92 downward to the retracted position. By this movement, as shown in FIG. 9, the guide rail 94, the push-up member 92, and the stopper member 96 are returned to their initial positions.
By repeating the above operation, the bar W is supplied to the bar processing machine one by one.

According to the second embodiment as described above, the following effects can be obtained in addition to the same effects as the first embodiment.
The second push-up position of the push-up member 92 is set to a height at which the bar W on the bar push-up surface 92A does not get over the holding portion 96A of the stopper member 96, so that only one bar W is taken out. The bar W can be held by the holding portion 96A. Therefore, the bar W can be prevented from rolling on the bar pressing surface 92A, the impact on the bar W can be reduced, and the vibration and noise of the bar feeder 90 can be suppressed.

  Since the stopper member 96 is configured to be movable from the bar take-out position to the bar guide position, the bar W pushed up by the push-up member 92 can be guided into the guide rail 94. Therefore, the bar W can be prevented from rolling on the bar pushing surface 92A and colliding with the guide rail 94, the impact on the bar W can be reduced, and the vibration and noise of the bar feeder 90 can be reduced. Can be prevented.

The present invention is not limited to the above embodiments, and various modifications are possible within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
For example, the feed arrow is not limited to the one arranged above the guide rail in the vertical direction, and the feed arrow may be arranged below the guide rail in the vertical direction, for example. Even in this case, by moving the guide rail and the feed arrow integrally in the vertical direction, these can be alternately matched with the feed axis.
Moreover, the arrangement | positioning relationship between a feed arrow and a guide rail is not restricted to what is arrange | positioned in parallel with a perpendicular direction, and any one should just be arrange | positioned in parallel above or below the other.

The feed arrow support means is not limited to the rollers arranged above and below, and any structure can be adopted as long as the feed arrow is supported so as to be movable toward the bar processing machine.
Although the feed arrow was cantilevered at the end on the side far from the bar processing machine, the present invention is not limited to this, and even if it has a structure that is supported in the guide rail as in the prior art, The objective can be achieved.

In the above-described embodiment, the bar member take-out position of the stopper member is set such that the holding portion 72D is located on the side of the guide rail 10 more than the radius of the bar member W from the stop portion 51B. Any position may be used as long as W is disposed on the push-up member and the bar W can be reliably pushed up by one when the push-up member moves upward. Therefore, the bar member extraction position of the stopper member may be set as appropriate in consideration of the inclination angle of the bar pressing surface, the diameter of the bar W, and the like.
Moreover, although the receiving position of the stopper member was set to a position where the holding portion 72D coincides with the stopping portion 51B in the above-described embodiment, the present invention is not limited to this, and the bar member W is sufficiently suppressed from receiving an impact. It is only necessary to sufficiently suppress the vibration of the feeder 1. Accordingly, the receiving position of the stopper member is preferably set in the vicinity of the position of the stopping portion 51B of the above-described embodiment in order to minimize the impact applied to the bar W and the bar feeder 1. It may be set as appropriate in consideration of the inclination angle of the material placement surface, the diameter and weight of the bar W, and even in this case, the object of the present invention can be achieved.

In the above-described embodiment, the push-up member reciprocating means is also used as the moving mechanism 60. However, the push-up member reciprocating means is not limited to this, and a push-up member reciprocating means for reciprocating the push-up member may be additionally provided. When the push-up member reciprocating means is provided separately, in the bar feeder of the second embodiment, it is not necessary to move the push-up member upward to the second push-up position and then to the delivery position.
The moving mechanism is not limited to an air cylinder, and any driving mechanism such as a servo motor can be employed. For example, when a servo motor is employed as the moving mechanism, the vertical distance adjusting means may be adjusted according to the rotation angle of the servo motor.
The vertical distance adjusting means is not limited to manually adjusting the vertical distance, but may be configured to be automatically adjusted when a diameter dimension is input to the controller. Arbitrary driving mechanisms, such as those using an air cylinder and those using a servo motor, can be adopted as the configuration of the vertical distance adjusting means and the stopper member reciprocating means.

  The controller is not limited to the one provided on the bar supply machine side, and may be provided on the bar processing machine side.

  The bar feeder and the bar processing system of the present invention can cope well even when used in an environment where noise needs to be suppressed. Moreover, since the dimensions can be easily set, it is suitable for supplying the bar to a bar processing machine that needs to handle various types of bar.
