Description

  The present invention relates to a plate stocker used for temporarily storing a surplus material generated by processing by a plate material processing machine or for storing a material plate material.

  In a plate processing machine such as a punch press, in addition to processing such as punching and forming, processing for cutting a product plate from a material plate by punching or the like is performed. In many cases, in order to emphasize the processing efficiency of the plate material processing machine, even if the size and shape of the product plate material to be cut out are different, the same material plate material is used. Therefore, depending on the type of product plate material, after the product plate material is cut out from the material plate material, there is a surplus material that still has a portion that can be processed into another product plate material. Conventionally, such surplus materials have been disposed of as waste materials without being effectively used.

On the other hand, the product plate material is carried out of the plate material processing machine by a plate material conveying device (for example, Patent Document 1) and temporarily stored in a plate material storage (for example, Patent Document 2) or loaded on a carriage to the next step. Transported. The surplus material is not conveyed by the plate material conveying device or stored in the plate material storage.

  As described above, conventionally, surplus materials have been disposed without being effectively used, and the usage of the materials has been wasteful. If a plurality of types of product plate materials are cut out from one material plate material, the above waste can be eliminated, but this is difficult for the following reasons. In other words, the processing schedule of the plate processing machine is basically to process the product plate in the order required in the subsequent process in order to avoid an increase in intermediate inventory and complicated product plate sorting operations. It has been established. For this reason, the same product plate material or the product plate material used in the same process is inevitably processed continuously, and the generation of excess material is inevitable.

Thus, it has been devised to temporarily store the surplus material generated by the plate material processing machine and return to the plate material processing machine when the surplus material becomes available later. In order to realize this idea, a facility for efficiently storing the surplus material is necessary. Since this equipment handles a weak extra-strength material that has been pulled out as a product plate material, it is required that the extra material is not subjected to excessive force during storage or loading / unloading so that the surplus material is not deformed. In addition, it is required that the surplus material is not misaligned during storage or loading / unloading so that the surplus material can be securely stored and the surplus material can be accurately supplied to the plate material processing machine during reuse.
In addition, it is possible to use a plate material transfer device and a plate material storage for product plate material for transport and storage of the surplus material, but this is a mixture of product plate material and surplus material, which hinders the transport and storage of product plate material. There are concerns about inconveniences such as confusion.

The pad mounting frame 71 is rotatable about a rotation shaft 72 located at the left end of the pad mounting frame 71. The turning operation is performed by the turning cylinder 73. By turning, the alignment direction of the suction pads 70 can be changed to a positioning position Q1 where the pair of suction pads 70 are arranged substantially side by side and a folding position Q2 where the pair of suction pads 70 are arranged side by side.

  The positioning means 75 includes a positioning cylinder 77 rotatable about a vertical axis 76 with respect to the pad mounting frame 71 and a pad pressing cylinder 78 mounted on a piston rod of the positioning cylinder 77, and the pad pressing cylinder A suction pad 70 is attached to 78 piston rods. The positioning cylinder 77 is configured so that the phase around the vertical axis 76 is elastically held in a neutral state by a pair of neutral holding springs 79. In a state where the pair of suction pads 70 are in the plate material holding position Q1, the positioning cylinder 77 in the neutral state is oriented at an angle of 45 degrees forward, backward, left and right.

  The operation of the plate stocker 3 when the plate material W such as the surplus material W1 generated in the plate material processing machine 1 is carried out to the plate stocker 3 will be described. First, as shown in FIG. 7A, the elevator 32 is moved up and down to the height of the stage for storing the plate material W, and the table member 31 at that stage is moved by the table advance / retreat drive mechanism 33 as shown in FIG. The elevator 32 is advanced to the advance position B, and the elevator 32 is stopped at the same height as the work table 5 as shown in FIG. The advancement of the table member 31 to the advance position B by the table advance / retreat drive mechanism 33 is performed by moving the drawer 52 forward while the front end portion of the table member 31 is held by the drawer gripper 53 as shown in FIG. . When the elevator 32 is moved up and down, the suction pad 70 of the plate material loading / unloading mechanism 35 is positioned at the folding position Q2 in order to prevent interference.

  Next, while gripping the left end portion of the plate material W on the work table 5 by the unloading gripper 67 of the plate material loading / unloading mechanism 35, the upper surface of the plate material W is sucked and held by the suction pad 70 at the plate material holding position Q1, In this state, the plate material holding head 63 is moved to the left by the traveling body 62 to pull the plate material W from the work table 5 onto the elevator 32. After the carry-out gripper 67 and the suction pad 70 release the plate material W, the plate material holding head 63 moves up and then moves to the right, returns to the original position through the elevator 32. When the plate material W is sucked by the suction pad 70, the pad pressing cylinder 78 is extended to press the suction pad 70 against the plate material W from above.

  The plate member W drawn on the elevator 32 is in a state of being placed on the placement surface 31a of the table member 31 as shown in FIG. From this state, the claws 53a and 53b of the drawer gripper 53 are closed and the front end portion of the plate member W and the front end portion of the table member 31 are sandwiched and fixed as shown in FIG. Then, the table member 31 on which the plate material W is placed is retracted to the storage position A by moving the drawer 52 rearward. Since the plate member W and the table member 31 are fixed by the drawer gripper 53, the plate member W on the table member 31 is not displaced when the plate member W is withdrawn. Thereafter, the drawer gripper 53 releases the plate member W and the table member 31, and the drawer 52 returns to the original position. In the storage position A, the plate material W on the table member 31 is kept stationary by the frictional force between the plate material W and the balls 31b.

  The operation of the plate stocker 3 when the plate material W of the plate stocker 3 is carried into the plate material processing machine 1 will be described. First, as shown in FIG. 10 (A), the elevator 32 is moved up and down to the height of the step where the plate material W is stored, and the plate member W at that step is moved together with the table member 31 as shown in FIG. The advance / retreat drive mechanism 33 is advanced to the advance position B, and the elevator 32 is stopped at the same height as the work table 5 as shown in FIG. The movement of the plate member W and the table member 31 to the advance position B by the table advance / retreat drive mechanism 33 causes the front end portion of the plate member W and the front end portion of the table member 31 to overlap with each other as shown in FIG. 9B. It is fixed by sandwiching it in the state, and the drawer 52 is moved forward.

  Next, the traveling body 62 is traveled to the right end portion of the guide rail 61 with the plate material holding head 63 raised, and the plate material holding head 63 is lowered. Then, the gripper 67 for carrying out grips the left end portion of the plate material W on the elevator 32, and the suction pad 70 at the plate material holding position Q1 sucks and holds the upper surface of the plate material W. The plate material W is pushed out from the elevator 32 onto the work table 5. At this time, the plate material W may be pushed out without being gripped by the carry-out gripper 67.

  In a state where the plate material W is pushed out onto the work table 5, the position of the plate material W may be shifted with respect to the work table 5 of the plate material processing machine 1 as shown in FIG. Therefore, as shown in FIG. 11B, after the unloading gripper 67 is opened and the plate material W is opened, the positioning cylinder 77 is extended to operate the pair of suction pads 70 forward and backward at an angle of 45 degrees. Project to the left. As a result, the front end portion of the plate material W is pressed against the work holder 14 of the plate material positioning mechanism 8 for positioning in the front-rear direction, and the left end portion of the plate material W is pressed against the end locator 80 for positioning in the left-right direction. .

  In the plate material processing machine 1, when an end material that does not have a portion that can be processed into another product plate material after cutting the product plate material W <b> 2 is generated, or on the table member 31 of each stage of the plate material stocker 3 is a surplus material or the like When it becomes full and it becomes necessary to make an empty table member 31, the end material or the surplus material is discarded in the order shown in FIG.

  FIG. 2A shows a state in which a plate member W made of an end material or a surplus material is placed on the table member 31 on the elevator 32, and the elevator 32 is lowered to the lowest end of the liftable range. From this state, the upper claw 53a of the drawer gripper 53 is closed to a position lower than the plate material W (FIG. 5B), and the discharge gripper 54 moves rearward to grip the front end portion of the plate material W (FIG. C)). Since the drawer gripper 53 and the discharge gripper 54 are arranged so as to be shifted from each other to the left and right, the both 53 and 54 do not interfere with each other.

  Then, by moving the drawer 52 rearward and pushing out only the table member 31 rearward (FIG. 4D), the rear end side of the plate member W is self-weighted when the rear end of the plate member W is detached from the table member 31. And is received by the end material discharging portion 36 ((E) in the same figure). At this time, the discharge gripper 54 rotates about the mounting shaft 55. Next, when the discharge gripper 54 moves forward while opening the claws 54a and 54b, the front end portion of the plate material W is detached from the discharge gripper 54 and falls into the end material discharge portion 36 ((F) in the figure). ).

  According to the configuration of the plate material stocker 3, the table member 31 moves back and forth between the storage position A and the advanced position B, and the elevator 32 moves up and down, so that the plate material W such as the surplus material generated in the plate material processing machine 1 is moved up and down. It can be efficiently stored on the table member 31 of a plurality of stages. Later, when the stored plate material W becomes available, the remaining material can be effectively utilized by returning the plate material W to the plate material processing machine 1 for processing. Since the entire lower surface of the plate material W placed on the mounting surface 31a of the table member 31 is supported from below, an excessive force is not applied to the plate material W during storage or loading / unloading. For this reason, even if the plate material W is a surplus material having low strength, it is difficult to deform.

When the table member 31 is moved back and forth between the storage position A and the advanced position B by the table advance / retreat drive mechanism 33, the plate member W placed on the mounting surface 31a of the table member 31 is moved by the drawer gripper 54 serving as a plate member fixing means. In order to fix to 31, the plate material W is not displaced on the placement surface 31 a. Therefore, the plate material W can be reliably stored, and the plate material W can be accurately supplied to the plate material processing machine 1 at the time of reuse.
In particular, in this embodiment, the plate material fixing means is a drawer gripper 54 that fixes the end portion of the plate material W and the end portion of the table member 31 in an overlapping state, so that the plate material W is any surplus material. Even if it exists, the board | plate material W and the table member 31 can be fixed reliably. That is, although the surplus material is removed from the inside, at least the end portion is left, so that the plate member W and the table member 31 can be sandwiched and fixed using the remaining end portion.

  In addition, since the plate material stocker 3 includes the plate material loading / unloading mechanism 35, the plate material W can be smoothly loaded and unloaded between the plate material stocker 3 and the work table 5 of the plate material processing machine 1. Since the plate material W carried into the work table 5 is positioned with respect to the work table 5 by the positioning mechanism 75 included in the plate material carry-in / out mechanism 35, the plate material W can be accurately supplied to the plate material processing machine 1. Therefore, after carrying in the board | plate material W, it can transfer to the process by the board | plate material processing machine 1 rapidly.

  Furthermore, since the front space of the elevator 32 is vacant, the plate material stocker 3 can manually place the plate material W on the table member 31 on the elevator 32 from the space side. Therefore, the raw material plate material or the surplus material once discharged from the plate material stocker 3 can be carried into the plate material processing machine 1 from the plate material stocker 3 side or stored in the plate material stocker 3. Thereby, the operation range of the plate material processing system is expanded.

  Furthermore, since the plate material W placed on the table member 31 on the elevator 32 can be discharged to the end material discharge portion 36 installed below the elevator 32 by the cooperation of the discharge gripper 54 and the drawer 52, The end material generated by the plate material processing machine 1 and the excess surplus material of the plate material stocker 3 can be discharged immediately at any time. As in this embodiment, when the end material discharge part 36 is a box with wheels 36a, disposal of the discharged plate material is easy.
