Other of movable rail frame 53 stop and decelerate position, are undertaken by each detector switch shown in Figure 9.Promptly, on movable rail frame 53, the detection head 76 that stretches out is set downwards, be provided with detect this detection head 76 respectively retreat end detector switch SW4, initial point decelerate position detector switch SW1, origin position detector switch SW0, preceding inlet side decelerate position detector switch SW2 and preceding inlet side detector switch SW3.Each detector switch SW0-SW4 is made of non-contact switch respectively.Above-mentioned detection head 76 is also used as the safety catch attachment.In the preceding inlet side of movable rail frame 53 and retreat end and each detection head 76 and engage and stop the block piece 78,77 (seeing Figure 13 B) that movable rail frame 53 moves and be located on the conveying frame 5a of plate conveyer 5.
As shown in Figure 8, the stop position of product chassis 4 is controlled by chassis position detecting switch LS1, LS2 with by the ground detection piece 79,80 that these switches LS1, LS2 detect.The chassis position detecting switch be installed in product chassis 4 below, constitute by limit switch.Detecting piece 79,80 is disposing corresponding to the " loaded " position P1 on the product chassis 4, P3 and chassis moving direction home position Y0 consistent location.
Below, the action of above-mentioned structure is described.Shown in Fig. 5 A, strap clamp pincers running body 55 waits for that in the origin position standby near plate working machine 1 work stage 2 processing of the sheet material W in the plate working machine 1 is over.Origin position is located on the position on the limit platform 57.After processing was over, product sheet material W was sent to the discharge position on the work stage 2, and at this moment, strap clamp pincers running body 55 advances with movable rail frame 53, and controlled sheet material W (Fig. 5 B) on the work stage 2 with clamp 13.Above-mentioned discharge position is the cooresponding directions X of end steady arm 48 (Fig. 2) position on sheet material end and the work stage 2, and is used as the said reference position Y0 (Fig. 7, Fig. 8) of Y direction.
The walking of strap clamp pincers running body 55 is carried out linkedly with movable rail frame 53 as following.That is, after the motor Mc of Fig. 1 made that movable rail frame driving belt V1 rotates, the movable rail frame 53 that combined tool 68 is combined on this belt V1 just moved (Fig. 3).Along with moving of movable rail frame 53, be bearing on this movable rail frame 53 and be mounted on interlock on the fixing belt V2 with belt pulley 67 rotations, be mounted on the running body driving belt V3 rotation on the inboard sheave portion 67b of this belt pulley 67.Because strap clamp pincers running body 55 combined tools 73 are combined on the running body driving belt V3, so this running body is along movable rail frame 53 walkings when rotating with belt V3.Like this, the driving of motor Mc is moved movable rail frame 53, therewith linkedly, and the walking on movable rail frame 53 of strap clamp pincers running body 55.Therefore, the speed of travel of strap clamp pincers running body 55 is that the moving velocity of movable rail frame 53 adds the speed of travel of strap clamp pincers running body 55 with respect to movable rail frame 53.
When the clamp 13 on the strap clamp pincers running body 55 was controlled sheet material W on the work stage 2, motor Mc reversed, and strap clamp pincers running body 55 retreats, and sheet material W is drawn on the roller platform 6 of plate conveyer 5.The " loaded " position P1 of past product chassis 4 goes up when loading, strap clamp pincers running body 55 retreat to the cooresponding position of " loaded " position P1 (Fig. 5 C), the reflecting plate 74 (Fig. 4) of movable rail frame 53 is detected by sensor S1, and motor Mc stops, and the walking of movable rail frame 53 and strap clamp pincers running body 55 just stops.
Then, the motor Mb hoist cable 61 that unrolls descends plate conveyer 5, stops during near the height of cargo-carring sheet material W on the product chassis 4 below its roller platform 6 (Fig. 5 D).This stops to move is to carry out when plate conveyer 5 following sheet material detecting sensor PS detect loading plate W by being located at.
Afterwards, the roller platform 6 of plate conveyer 5 rotates according to arrow b direction, keeps out of the way upper path (Fig. 6 A), is loaded in the sheet material W above it, under the state that the one end is being controlled by clamp 13, on the product chassis 4 that hangs on the cargo-carring sheet material W.At this state, roller platform 6 does not disturb mutually with loading plate W, and plate conveyer 5 is further descended (Fig. 6 B), and clamp 13 is arrived near the height above the loading plate W.Then, open clamp 13 moves back strap clamp pincers running body 55 after a while, just has been loaded on the cargo-carring sheet material W transporting sheet material W.
After such loading is finished, the plate conveyer is risen return former height,, make strap clamp pincers running body 55 return origin position (Fig. 5 A) with movable rail frame 53 with the make position that its roller platform 6 is got back to down side path.In addition, at this moment make product chassis side travel (Fig. 7 B, Fig. 8 B), prepare the loading of next sheet material W " loaded " position P2.Above-mentioned repeatedly in this wise action is loaded into " loaded " position P2 transporting sheet material W.
When carrying out the loading of next sheet material W, do not carry out the side travel of product chassis 4 toward " loaded " position P3, when strap clamp pincers running body 55 is pulled out next sheet material W, shown in Fig. 6 D, stop at the cooresponding position of " loaded " position P3 on.This stops action and carries out when detecting reflecting plate 74 at sensor S2 (Fig. 4).
Like this, by the stop position of assemblage zone clamp running body 55 and the traversing moving stop position of product chassis 4, just can be loaded on 4 " loaded " position P1～P4 on the product chassis 4 transporting sheet material.In this case, preferably be loaded on each " loaded " position P1～P4 one by one successively, each position balance ground loads on product chassis 4 like this, in addition, also can be when plate conveyer 5 descends, reduce the height of clamp 13, the horizontal changing of the relative positions in the time of can preventing that sheet material W from leaving clamp 13 apart from loading plate W.If increase the stop position of strap clamp pincers running body 55 and the stop position of product chassis 4, just can be divided in sheet material on the more " loaded " position.In addition, when sheet material W is a large-sized plate, also " loaded " position P1 can be loaded as benchmark, can be benchmark with the center of product chassis 4 also perhaps, loads to bilateral symmetry.
According to this device for discharging, the movable rail frame 53 with strap clamp pincers running body 55 guide track 53a is moved forward and backward, can make strap clamp pincers running body 55 cross limit platform 57 near plate working machine 1.Therefore, when opening limit platform 57 maintenance examination plate working machines 1 etc., movable rail frame 53 is drawn in main body frame 51 sides, just can guarantee operator's path.In addition, different machines according to plate working machine 1, adding man-hour,, can avoid the sheet material delivering mechanism and the device for discharging of work holder 41 grades of plate working machine 1 to disturb by strap clamp pincers running body 55 is drawn in main body frame 51 1 sides together with movable rail frame 53.Like this, in glitch-free top position guide track is set just can resembling in the prior art, therefore, simple structure.In addition, owing to make the walking on the movable rail frame 53 of advance and retreat of strap clamp pincers running body 55, so, can accelerate the actual speed of travel that strap clamp clamps running body 55, shorten dumping time.
In addition,, can save the bay-lift that on the product chassis, is provided with in the technology before by lifter plate material conveyer 5, so, even on product chassis 4, during loading plate W, also can stably load inclined to one side.Plate conveyer 5 is designed under the liftable situation, though can cause the interference problem of guide track 53a and main body frame 51, because the movable rail frame 53 that is located on the guide track 53a can be drawn in the plate conveyer 51, therefore, can not influence lifting.Therefore, for example just needn't the part of stretching out from main body frame 51 of guide track 53a and part branch in the plate conveyer 5 be arranged and be bearing on the ground, like this, structure is able to simple.In addition, because the advance and retreat of the walking of strap clamp pincers running body 55 and movable rail frame 53 are by interlinked mechanism 66 interlock mechanically, both can be driven by same motor Mc, reduce drive source quantity, also make simple structure.
Below, the detailed construction of clamp 13 and cancel system thereof is described.This clamp need not be controlled and be used drive source, but relies on wedging action to control, and its structure is simple.Figure 15 A, B are respectively its lateral plan and front elevation.The rearward end of the main body 14 of clamp 13 is connected by the fagging 16 of fulcrum 15 with strap clamp pincers running body 55 front ends, connects the pars intermedia of clamp body 14 and the front end of fagging 16 by extension spring 17, and like this, main body 14 can support around fulcrum with swinging up and down.This clamp body 14 is made of pair of right and left side plate 14a, 14b, and the upper end of side plate 14a is connected by the horizontal fulcrum 18 perpendicular to running body 55 advance and retreat directions, and the bottom is connected by the fixedly maxillary plate 19 that front end is blade-like.
On above-mentioned horizontal fulcrum 18,3 kinds of movable acia 20a, 20b, 20c in hanging rotationally, the end that these acias are held sheet material W up and down under the arm with fixing maxillary plate 19.It below each movable acia 20a～20c the arc-shaped bend face.The center of curvature of this plane of bending is to set like this; That is, for and fixedly above the sheet material W on the maxillary plate 19 between produce wedging action, connect axle center and the inclined abrasive angle α of the straight line between the sheet material W contact P (Figure 21) as the horizontal fulcrum 18 of pivot point.In addition, as shown in figure 15, the distance between the following and horizontal fulcrum 18 of each movable acia 20a～20c is inequality, can switch the movable acia 20a～20c that holds sheet material W under the arm according to the thickness of sheet material W like this.
Each movable acia 20a～20c is connected on side's side plate 14a of tong bodies 14 by extension spring 21a, the 21b, the 21c that apply the initial stage thrust pressure, and the trend of forwards rotating is arranged.Notch part 22b, the 22c of the movable last formation of acia 20b, 20c is used to avoid the connecting portion of extension spring 21a, 21b and movable acia 20a, 20b to disturb.
In the face side of side's side plate 14a of tong bodies 14, the pars intermedia of relieving rod 23 is installed on the above-mentioned horizontal fulcrum 18 swingably, and this relieving rod is to controlling of sheet material W movable acia 20a-20c rearward to be rotated in order to remove.In the bottom of relieving rod 23, prominent establishing removed pin 25, removes the pin 25 circular-arc long guide holes 24 (Figure 14) that run through on the side plate 14a, and be chimeric with embedded hole 26a, 26b, the 26c of each movable acia 20a～20c.These embedded holes 26a～26c is the circular-arc slotted hole along long guide hole 24.
Be used to be provided with the fagging 16 of tong bodies 14, be installed on the framework 12 that the aluminium section bar by running body 55 constitutes by screwed part 45 and joint fastener 46, this installation site can be in the direction adjusted perpendicular to direction of travel.
With respect to relieving rod 23, be provided with and make it toward the bar operating mechanism 27 (Figure 14) of removing the side rotating operation, bar operating mechanism 27 is made of the parallel linkage 29 on lifting bar 28 that is arranged on running body 55 sides and the conveying frame 5a that is arranged on plate conveyer 5.The midway location installation portion 30 of lifting bar 28 can be connected on the fagging 31 by fulcrum 32 with swinging up and down, and this fagging 31 is fixed on the running body frame section 12.The extension spring 33 that lifting bar 28 is connected installation portion 30 upper ends and fagging 31 rear ends side is upward exerted pressure.Touch roll 34 with relieving rod 23 upper ends below the lifting bar 28 of this state joins, and each movable acia 20a～20c of clamp 13 is restricted to sagging posture.At the front end of fagging 31, to dash forward and establishing stop pin 36, this stop pin 36 runs through the stop slotted hole 35 (Figure 15 A, Figure 15 B) of installation portion 30 bottom surfaces of lifting bar 28, like this, makes the flat-hand position of lifting bar 28 become the boundary of swing upward.
Below, the on-off action of clamp 13 is described.Shown in Fig. 5 B, when strap clamp pincers running body 55 moved to sheet material W end on the work stage 2, the movable acia 20a of clamp 13 was pushed away by sheet material W, and opposing extension spring 21a rearward rotates shown in Figure 19 A.Here, the thickness of sheet material W is than the lower end of movable acia 20b, 20c and fixedly the gap between maxillary plate 19 top is thin, than movable acia 20a and fixedly the gap between the maxillary plate 19 is thick.Therefore, movable acia 20b, 20c are not pushed away by sheet material W, are still keeping sagging posture.
At this moment, tong bodies 14 can swing up and down around fulcrum 15, and fixedly the front end of maxillary plate 19 forms blade-like, so, even the end of sheet material W is because of deadweight " sagging " or " warpage " etc., the sheet material W that also can not influence on the work stage 2 correctly passes in and out between the 20a of jaw up and down, 19 of clamp 13.Along with this action, the end of sheet material W enters movable acia 20a with fixedly between the maxillary plate 19, and jaw 20a, 19 clamps about being somebody's turn to do.
When sheet material detector switch (figure do not show) detects after sheet material W entered, strap clamp pincers running body 55 just responds this detection signal, begins to retreat with movable rail frame 53.Along with this backward movement, sheet material W again will be from deviating between the jaw 20a, 19 up and down, and therefore, shown in Figure 19 B arrow a, movable acia 20a is returned to sagging posture again from the position of rearward rotating.At this moment, owing between the lower surface of movable acia 20a and the sheet material W wedging action is arranged, therefore, sheet material W is clamped in up and down between the jaw 20a, 19 against friction force.Along with retreating of running body 55, sheet material W is pulled on the plate conveyer 5 from the workpiece 2 of Fig. 2.Because spring 21a gives and initial stage thrust pressure of movable acia 20a,, can not occur skidding, controlling bad etc. so above-mentioned wedging action is produced effectively.
Sheet material W is pulled to the desired location on the plate conveyer 5, and when unloader 7 stopped, roller platform 6 was kept out of the way (Fig. 6 A) to the last siding track of loop chain 9.Then, shown in Fig. 6 C, plate conveyer 5 drops to predetermined altitude, and roller platform 6 is kept out of the way, and shown in Figure 20 A, roller platform 6 joins with the contact component 44 of parallel linkage 29, and down-pressed pole 37 antagonistic springs 41 are pushed to the rear.Like this, down-pressed pole 37 is just from highly dropping to height shown in the dotted line shown in the solid line.Because this decline, lifting bar 28 are pressed down bar 37 and promote shown in Figure 20 B, swing downwards from flat-hand position opposing extension spring 33.Thereupon, relieving rod 23 swings of clamp 13 are removed pin 25 and are rearward moved in long guide hole 24.Its result, remove pin 25 and embedded hole 26a～26c chimeric movable acia 20a～20c rearward rotate, removed controlling of the upper jaw and the lower jaw plate 20a, 19 couples of sheet material W.Like this, sheet material W just falls.
When sheet material W was thicker slightly than above-mentioned sheet material, the longest movable acia 20a did not produce wedging action, and produced wedging action between the movable acia 20b of intermediate length and sheet material W, sheet material W can be controlled.If sheet material W is thicker again, then produce wedging action by the shortest movable acia 20c, sheet material W can be controlled.
This clamp 13 does not need to control to control with drive source and releasing uses drive source, but along with the grip plate material is controlled and removed in the action of plate conveyer 5.Therefore.Simple structure, and do not need to control the control signal that begins and control releasing, so control is also simple.
In addition, the down-pressed pole 37 of parallel linkage 29 is that fore-and-aft direction ground lengthwise is being provided with, and by this down-pressed pole 37 lifting bar 28 of strap clamp pincers running body 55 sides is depressed, so the stop position that the releasing action of clamp is not limited to running body 55 also can carry out.Therefore, during with respect to the center reference loading plate W of product chassis 4, also can carry out the loading of the sheet material W of various front and back width, in addition, when the sheet material branch being installed on the product chassis 4 some positions, also can carry out the switching of clamp 13 in desired location.And, because lifting bar 28 is the pole stocks that extend along perpendicular to running body 55 direction of travel, because lifting bar 28 is the pole stocks that extend along perpendicular to running body 55 direction of travel, so, can side by side carry out the releasing of several clamps 13, and, not only can remove action, and can remove action by the operation of relieving rod 23 by the installation site of regulating clamp 13.
Like this, can be arranged on strap clamp pincers running body 55 on the movable rail frame 53 by using, the clamp 13 that its interlinked mechanism 66 is set and is handled by wedging action has just formed that drive source is few, simple structure, device for discharging that cost is low with walking.
Figure 22 is another embodiment of the interlinked mechanism of movable rail frame 53 and strap clamp pincers running body 55.In this interlinked mechanism 90, but the miniature gears 93 that can be rotated to support on the movable rail frame 53 meshes with the carry-over bar 92 that is located at the stationary rack 91 on the plate conveying frame 5a and be located on the strap clamp pincers running body 55.Make the same of belt V1 that movable rail frame 53 moves and drive system and the foregoing description.When adopting this structure also with the foregoing description similarly, adopt a motor Mc that movable rail frame 53 and strap clamp pincers running body 55 are moved linkedly.
In addition, in the various embodiments described above, strap clamp pincers running body 55 is located on the movable rail frame 53, but also can clamp that conveying frame 5a that running body 55 can be set directly at plate conveyer 5 with walking goes up to strap clamp or main body frame 51 on.In addition, also can wait the clamp 13 that replaces running body 55 with magnet, vacuum suction seat.
