BACKGROUND OF THE INVENTION
  The present invention relates to a shearing member conveying apparatus that efficiently conveys a sheared plate-shaped member to a press machine or the like in the next process without damaging and easy handling.
[0002]
[Prior art]
  In press working such as drawing or punching, a so-called sheet made of a thin metal plate having a width of about 900 mm and a length of about 1800 mm is often supplied as a raw material. In order to make this sheet into a size corresponding to a press or a product, the sheet is cut into a predetermined width by a shear (shearing machine). For example, when a high speed shear is used, the cut sheet is quickly cut at a speed of about 60 m / min. In addition, a sheet cut to a predetermined size by shearing (referred to as a shearing member in the present application) shifts to a press process such as a punching process, which is the next process, and therefore needs to be conveyed to a press machine. In this case, there can be a method of receiving the shearing member in a box and conveying the whole box separately, or a method of conveying one by one, but in order to increase the efficiency of conveyance and handling, a large number of sheets are laminated and bound by a band or the like It was often transported by forklifts and hoists.
[0003]
[Problems to be solved by the invention]
  However, the method of receiving the shearing member falling from the conveyor with a box has a problem that it is easily damaged when dropped, and that it is very inefficient to carry one by one. On the other hand, when a large number of sheets are stacked and conveyed by a forklift or the like, the efficiency is good, but there are the following problems. The shearing members often have sharp edges formed by the shearing, or they are formed with barbs. When such shearing members are laminated, they are rubbed at the time of laminating and transporting and are damaged at the edges. There was a problem that the product value was lost. In addition, there is a problem that when the sheeting members laminated in the next step are fed one by one to the press machine, they are rubbed and scratched.
[0004]
  In order to solve the above-mentioned problems, the present invention provides a shearing member transport device that can easily handle a plate-like member sheared by a shear, is easy to handle, and can be efficiently transported to a press machine in the next process. The purpose is to do.
[0005]
[Means for Solving the Problems]
  In order to solve the above-mentioned problems, in the shearing member conveying device of the present invention, a shearing is a thin plate member that includes a bottom portion and a plurality of parallel partition plates provided vertically from the bottom portion, and is sheared between the partition plates.

The magazine vertical movement hand which displaces the shearing member to the position where the gap between the partition plates can be sequentially filled. The magazine is moved to a predetermined position by the magazine vertical movement means, the partition plate is rotated by the magazine rotation means again in the vertical direction, and the magazine released from the holding by the magazine holding means can be conveyed. And a conveying means.
[0006]
  In this shearing member transport device, since the shearing member transported from the shear can be sequentially filled between the partition plates of the magazine leveled by using the magazine vertical movement means, the shearing members held between the partition plates are rubbed together. There will be no scratches. In addition, since the partition plate that is horizontal so that it can be filled easily during filling, the magazine rotating means is rotated so that the partition plate is vertical during transport, so that the magazine even if the filled magazine tilts. Thus, the shearing member held in the casing does not fall off. For this reason, the magazine can be easily transported, and for example, it can be stably transported with a hoist or the like, so that facilities for transport can be simplified. Furthermore, by storing in a magazine, accurate positioning becomes possible, and a robot or the like can be used, so that handling in subsequent processing becomes easy.
[0007]
  The present invention is provided with detection means for detecting a shearing member conveyed from the shear, and includes a control means for vertically moving the magazine vertical movement means at intervals of each partition plate in synchronization with the conveyance of the shearing member from the shear. An automatic filling control means for automatically filling the magazine with the shearing member may be provided. If comprised in this way, the filling of the magazine of a shearing member will be automated and work will become easier.
[0008]
  Also, it is desirable that the empty magazine transporting means and the filling magazine transporting means are arranged in parallel in the vertical direction. With this configuration, the area occupied by the apparatus can be reduced, and the empty magazine can be replenished to the empty magazine transport means and the filled magazine can be collected at the same time, so that operations can be performed continuously.

This creates a gap between the first magazine 2b and the second magazine 2c.But keep this gapTherefore, as shown in FIG. 7, the second stopper 34 is protruded to restrict the movement of the second and subsequent magazines 2 to the back surface.
[0035]
  Next, as shown in FIG. 3, it is pressed from both sides by the side pushers 38 arranged on the left and right sides of the magazine 2, and the position in the width direction is regulated and fixed. Further, as shown in FIG. 8, the horizontal clampers 36 and 37 disposed on both sides of the magazine 2 sandwich both end portions of the bottom portions 21 b and 21 d of the magazine 2 from above and below. Thus, the front clamp 41 is positioned in the front-rear direction, and the horizontal clampers 36, 37 firmly fix the vertical direction and the side pushers 38, 38 in the left-right direction. And the roller 35c of the pusher 35 which was pressing the bottom part 21b from the front side is drawn under a conveyance path.
[0036]
  Next, as shown in FIGS. 8 and 9, the magazine 2 clamped by the magazine clamper 4 is rotated 90 ° to the back side about the rotation shaft 41 b by the magazine rotating device 5. Then, as shown in FIG. 11, the shearing member 8 moved upward by the magazine lifter 6 and conveyed by the belt conveyor BC is placed in the gap between the uppermost partition plate 23a and the lower partition plate 23b. It stops at the position where it can be inserted. Then, the position of the magazine 2 is detected by the sensor, and the shearing member 8 is conveyed and filled between the partition plate 23a and the partition plate 23b from the shear SH (see FIG. 1). When this filling is completed, the completion of filling is detected by the sensor, and the magazine 2 is raised by one interval of the partition plate 23 by the magazine lifter 6. Then, the next shearing member 8 is conveyed and filled between the partition plate 23b and the partition plate 23c from the shear SH (see FIG. 1). When such operations are sequentially repeated and the shearing member 8 is filled on the partition plate 23d disposed at the bottom, the filling of the magazine 2 is completed, and the conveyance of the shearing member 8 from the shear SH is stopped. . These operations are sequence-controlled by a dedicated sequencer while confirming the operations one by one with the sensor. Needless to say, sequence control using a general-purpose computer, control using numerical control entered in advance, NC control, image recognition, and the like may be performed.
[0037]
  Thus, the magazine 2 that has been filled is raised by the magazine lifter 6 and stopped at the rear side end of the filled magazine transport conveyor 7 shown in FIG. 12, and the magazine rotating device 5 rotates the rotating shaft 41b to the front side. Is rotated around. Then, the clamp by the magazine clamper 4 is released. The magazine 2 whose clamp has been released is detected by a sensor, conveyed to the front side by a filling magazine conveyance conveyor 7 driven by a drive motor 71, and is stopped by a stopper 73 (see FIG. 2) provided at the front side end. The drive motor 71 is stopped by contact and detected by the sensor.
[0038]
  Magazine 2 filled in this way, ZhouKnowledge hoistHO (see Figure 1)Etc., and is conveyed to a shearing member supply conveyor (not shown) provided near the press. At this time, in the case of the shearing member 8 shorter than the magazine 2, the end portion of the shearing member 8 is filled with the one fall prevention plate 28a (see FIG. 15), and the fall prevention plate 28a is inclined downward. When transported by a hoist or the like, the end portion of the shearing member 8 is aligned by the fall prevention plate 28a, and the longitudinal position of the shearing member 8 in the magazine 2 can be made accurate. The shearing member supply conveyor has the same configuration as that of the filling magazine transport conveyor 7, and the magazine 2 is placed at a predetermined position. At this time, since the shearing member 8 aligned in the magazine 2 is placed at an accurate position, it can be accurately positioned on the three-dimensional coordinates and can be handled by various robots. Further, as shown in FIG. 13, the shearing member 8 filled in the magazine 2 can be easily gripped one by one because the central portion indicated by the arrow is exposed, and this is gripped by a robot hand or the like. Further, since the gripped portion is the center of gravity of the shearing member 8, stable handling can be performed even when one robot hand is used. Of course, more stable handling is possible by gripping with a plurality of robot hands. Therefore, the shearing member 8 is gripped by a robot or the like installed in the vicinity of the magazine 2 and automatically supplied to the press machine.
[0039]
  As described above, the shearing member conveyance device of the present embodiment has the following effects. That is, the shearing member 8 that has been manually transported is automatically loaded into the magazine 2 by the apparatus linked to the shear SH, and can be transported in units of the magazine 2, so that the work efficiency is greatly improved. is there.
[0040]
  In particular, in the shearing member transport device 1 of the present embodiment, the shearing member 8 transported from the shear SH can be sequentially filled between the partition plates 23 of the magazine 2 leveled using the magazine lifter 6. There is an effect that the shearing members 8 held between the partition plates 23 are not rubbed and are not damaged.
[0041]
  In addition, since the horizontal partition plate 23 is rotated by the magazine rotating device 5 so that the partition plate 23 is vertical during conveyance so that the filling is easy when filling, the magazine 2 may be tilted even if the magazine 2 is tilted. There is an effect that the shearing member 8 held by 2 does not fall off. In particular, since the magazine 2 is also provided with a fall prevention plate 28, it is more difficult to fall off. For this reason, the magazine can be easily transported, and for example, it can be transported even with a hoist or the like, and the equipment for transport can be simplified.
[0042]
  Further, since the magazine 2 is rotated by the magazine rotating device 5 so that the partition plate 23 is vertical, the lower end portion of the stored shearing member 8 is brought into contact with the bottom portion of the partition plate 23 so that the end portions are aligned and accurately positioned. Can do. Furthermore, since the position of the shearing member 8 is determined by accommodating the shearing member 8 in the magazine 2 having the fall prevention plate 28 in the longitudinal direction, the shearing member 8 can be accommodated in an accurate position. Therefore, since this position can be grasped as a numerical value on the three-dimensional coordinates, it can be used even by an NC-controlled robot without feedback such as image recognition, and there is an effect that handling in subsequent processing can be automated at low cost.
[0043]
  In addition, since the shearing members 8 are separated one by one by the partition plate 23, they can be easily grasped one by one by the robot hand. For this reason, there is no need for a step of manually separating the laminated shearing members 8 one by one, which not only facilitates the work but also prevents the occurrence of scratches in the separation step.
[0044]
  Since the partition plate 23 is filled so that the center of gravity of the shearing member 8 is exposed, the center of gravity of the shearing member 8 can be gripped by the robot, and there is an effect that handling is stabilized.
[0045]
  In addition, a sensor (not shown) for detecting the shearing member 8 conveyed from the shear SH is provided, and control means for vertically moving the magazine lifter 6 every interval between the partition plates 23 in synchronization with the conveyance of the shearing member 8 from the shear SH. And a control unit 9 which is an automatic filling control means for automatically filling the magazine 2 with the shearing member 8 is provided. For this reason, the filling of the shearing member 8 into the magazine 2 is automated, and the operation is further facilitated. In addition, the control unit 9 detects the position of the magazine 2 with each sensor, and controls the empty magazine transport conveyor 3, the magazine clamper 4, the magazine rotating device 5, the magazine lifter 6, and the filling magazine transport conveyor 7 as described above. And the operation of the apparatus can be automated.
[0046]
  As mentioned above, although this invention was demonstrated by embodiment, it cannot be overemphasized that this invention is not limited to these.
[0047]
  For example, by providing the filling magazine conveyor 7 continuously to the vicinity of the press machine, the conveyance by a hoist, a forklift, or the like may be made unnecessary. Alternatively, the empty magazine transfer conveyor 3 and the filling magazine transfer conveyor 7 may be configured upside down, and the operation of filling the magazine 2 with the shearing member 8 may be performed from above to below. Needless to say, the length and direction of the conveyor can be changed as appropriate.
[0048]
  In this embodiment, control including shearing is sequence control by a dedicated sequencer. However, sequence control using a general-purpose computer, NC control, control by image recognition using a CCD camera, etc. It can also be implemented by manual operation.
[0049]
  In addition, the shape of the magazine 2, the quantity / arrangement / shape of the partition plate 23, the position / shape / quantity of the magazine clamper 4, the magazine rotating device 5, the magazine lifter 6, etc. It can be implemented with changes. Further, the drive source can be selected as appropriate depending on the size, weight, etc. of the magazine 2, such as air pressure, hydraulic pressure, solenoid, and motor. And it can change and improve by those skilled in the art without departing from the scope of the claims.
[0050]
【The invention's effect】
  In the shearing member transport device of the present invention, since the shearing member transported from the shear can be sequentially filled between the partition plates of the magazine leveled using the magazine vertical movement means, the shearing members held between the respective partition plates There will be no scratches caused by rubbing. In addition, since the partition plate that is horizontal so that it can be easily filled when being filled is rotated so that the partition plate becomes vertical by the magazine rotating means at the time of transportation, the magazine is filled even if the filled magazine is tilted. Thus, the shearing member held in the casing does not fall off. For this reason, the magazine can be easily transported, and for example, it can be stably transported with a hoist or the like, so that facilities for transport can be simplified. Furthermore, by accommodating in the magazine, it is possible to perform accurate positioning and use of a robot or the like, thereby facilitating handling in subsequent processing.
