DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet conveying apparatus for carrying a material sheet into a sheet processing machine and unloading a product sheet.

[0002]

2. Description of the Related Art Heretofore, as a loader for loading a material plate into a plate processing machine and an unloader for unloading a product plate from the plate processing machine, a traveling body provided with a plurality of suction pads for sucking the surface of the plate has been used. I have. The loader and the unloader are independent devices, or the loader and the unloader have a configuration in which the rail of the traveling body is shared.

[0003]

In the conventional loader and unloader of this type, since the distance between the suction pads provided on the traveling body is fixed, the size and shape of the material plate and the product plate are reduced. In the case of a change, proper suction cannot be performed, and there is a problem that only a plate having a predetermined size and shape can be transported. For this reason, it is also performed to stop the suction of some of the suction pads to deal with the size of the plate material, but when unloading a small product plate material, if the arrangement range of the suction pad is widened, In some cases, the suction pad and its supporting frame interfere with the plate material processing machine, thereby causing an obstacle in carrying out. Even when the conveyed product plate is placed on the plate storage device, the suction pad and its supporting frame may interfere with the plate storage device, which may hinder the placement. Further, when an attempt is made to cope with a small plate material by stopping the suction of some of the suction pads, the spacing between the suction pads may be wide and proper suction may not be performed. If the arrangement of the suction pads is dense, this problem can be solved, but the number of suction pads becomes too large and the cost increases. Further, since the conventional loader and unloader are dedicated machines, even if the arrangement intervals of the suction pads are fixed, there is relatively little trouble,
If the same suction pad is used for both the loader and the unloader, it is difficult to deal with the size of the plate material, the plate material processing machine, the plate material storage device, and the like. That is, the product plate may be cut into a plurality of pieces with respect to the material plate, and the dimensional difference from the material plate may be large. In such a case, it is difficult to cope with the size of the plate material and to prevent interference with the plate material processing machine and the plate material storage device with the device for the fixed distance between the suction pads.

[0004] An object of the present invention is to carry out transfer according to plate materials of various sizes and shapes, or to carry according to the surrounding conditions, and to perform both transfer of the raw plate material to the plate processing machine and unloading of the product plate material. An object of the present invention is to provide a plate material conveying device. It is another object of the present invention to be able to adapt to special specifications of a plate processing machine and a plate storage device.

[0005]

According to the present invention, there is provided a sheet conveying apparatus for carrying a material sheet into a sheet processing machine and unloading a processed product sheet from the sheet processing machine. A suction pad array in which a plurality of suction pads for suction are arranged is provided, and the spacing between the suction pads of the suction pad array can be changed. According to this configuration,
By changing the spacing of the suction pads, it is possible to respond to differences in the size and shape of the plate material to be transported, and to handle these conditions in accordance with the conditions of the plate material processing machine, the place where the material plate material is placed, the destination where the product plate material is carried out, etc. Loading and unloading can be performed without interfering with a processing machine or the like.

In the present invention, the product plate material is carried out to a plate material storage device, and a variable suction pad interval of the suction pad array is changed according to the environment of the plate processing machine or the plate material storage device. It may be done. The environment of the plate processing machine includes, for example, the width and moving range of the table for placing the plate in the plate processing machine, the discharge position of the product plate on the table, the positioning position for loading the material plate, the frame above the table or the frame. This is the arrangement status of an interference target such as a body cover. The environment of the plate material storage device refers to, for example, the size of a product pallet, the presence of peripheral objects of the pallet for transporting the product pallet, and the like. As described above, when the interval between the suction pads is changed in accordance with the environment of the plate processing machine or the plate storage device, it is necessary to adapt to various specifications such as a special specification of the plate processing machine or the plate storage device. Can be.

In the present invention, the changeable suction pad interval of the suction pad array may be changed according to the size or shape of the material plate or the product plate. This makes it possible to adapt to various sizes and shapes of raw material and product material.

It is possible to freely enter between.

The operation of the plate material transporting apparatus 3 having the above configuration will be described. First, the schematic operations of loading and unloading will be described. In the material storage section 22 of the plate material storage device 2, a material plate material W1 is stacked in a stacked state on a material pallet 22a. When the material plate material W1 is carried into the plate material processing machine 1, the suction pad array 36 of the traveling body 27 is moved to the material plate material W1 of the material storage portion 22.
The traveling body 27 is moved in the X and Y directions so that The movement of the traveling body 27 in the Y-axis direction is performed by the movement of the movable platform 26 in the Y-axis direction. (Even in the following description of the operation, the description of the movement of the traveling body 27 in the Y-axis direction refers to the movement of the traveling body 27 due to the movement of the movable base 26 in the Y-axis direction.) In this state, suction is performed. The pad array 36 is mounted on the traveling body 27.
From each of the suction pads 3 of the suction pad array 36.
5, after the material plate material W1 is sucked, the suction pad array 36
Is raised again. In this manner, the traveling body 27 is moved toward the plate processing machine 1 and the movable table 26 is moved in the Y-axis direction while the workpiece W1 is gripped by the traveling body 27, and the suction pad array 36 is lowered. Then, the material plate material W1 is carried into a predetermined carry-in position on the table 5 of the plate material processing machine 1.
In this example, as shown in FIG. 1, when the carriage 7 is at the retreat end, the positions where the two sides of the material plate W1 contact the work holder 12 and the end locator 17 are the predetermined carry-in positions. The reference position that is the corner of the plate material at the carry-in position is indicated by a key mark M1 in FIG. The pressing of the material plate W1 onto the work holder 12 and the end locator 17
After the material plate W1 is dropped on the table 5, the traveling body 2
7 is moved in the X and Y directions.

The product sheet material W2 obtained by processing the material sheet material W1 by the sheet material processing machine 1 is discharged from a predetermined product sheet material discharge section A on the table 5 of the sheet material processing machine 1 or an arbitrary discharge position. When the product plate material W2 is cut off using the sub head 5, the predetermined product plate material discharge portion A is located near the sub head 5 as described above. This emission is generated by the traveling body 2
7 is moved to the discharge section or the discharge position, the suction pad array 36 is lowered to suck the product plate material W2, and after the suction pad array 36 is lifted, the traveling body 27 is moved to the plate storage device 2.
This is performed by moving the product onto the product storage unit 21 and lowering the pad array 36 to release the suction of the suction pad 35. The arrangement of each product plate material W2 on the product storage unit 21 is, for example, a so-called figure stand. That is, when a plurality of product plate materials W2 are cut out from the material plate material W1 by the plate material processing machine 1, the product plate materials W2 are arranged in the product storage unit 21 so as to be arranged in a state where the product plate material W2 is cut with respect to the material plate material W1. Load. Also in the case where the product plate materials W2 are stacked side by side as described above, the traveling body 27 is also in the orthogonal biaxial directions (X, Y).
Direction), and can be freely performed by moving the traveling body 27.

The skeleton S remaining on the table 5 by the processing by the plate material processing machine 1 grips the edge of the skeleton S by the gripper 52 provided on the traveling body 27, and moves the traveling body 27 to move the skeleton storage unit 23. Until the table 5 and the auxiliary table 4 are dragged, they are carried out.

Next, the loading and unloading operations will be described in detail. FIG. 8 shows various forms of the suction pad array 36 at the time of loading the material. FIG. 7A shows a case where the expansion and contraction frames 33b and 33c on both sides of the suction pad array 36 are unloaded and carried out, that is, a case where the space between the suction pads on both sides is widened and carried out. FIG. 2B shows a case where the carry-out is performed with the suction pad on one side widened, and FIG. 3C shows a case where the carry-out is performed with the space between the suction pads on both sides narrowed. FIG.
(C) shows three types and sizes of raw material W1.

As shown in these figures, by appropriately widening or narrowing the spacing between the suction pads of the suction pad array 36, it is possible to carry the sheet material W1 in accordance with the size and shape thereof, and to perform the transfer in accordance with the size of the suction pad array 36. 36 does not take up extra space and can be carried in according to the environment of the plate processing machine 1. For example, in a state where the traveling body 27 is moved to the forward end toward the plate processing machine 1 side, the suction pad array 36 is mounted on the upper frame 14 or the like of the plate processing machine 1 irrespective of the size and shape of the material plate W1. Without the problem of interference, the material plate W
1 can be carried into a predetermined carry-in position where it contacts the end locator 17. In the case of carrying in, the suction pad 35 of the suction pad array 36 is suctioned only by a general one and the suction pad 35 _{A of the} small pad group is used in any of the cases shown in FIGS. , it may be allowed to stop the suction of 35 _B. In addition, all the suction pads 35, 3
Suction may be performed at 5 _A or 35 _B.

FIGS. 9 to 11 show various forms of the suction pad array 36 when the product is carried out. These figures are examples in which the product plate W2 is cut into a plurality of pieces or smaller than the material plate W1, and the state in which the product plate W2 is in the product plate unloading section A of the plate processing machine 1. Show. In these figures, the suction pads 35 denoted by NG are cut off the suction path and stopped. For example, in FIG. 7A, the suction pads 35 in the rightmost row are not only placed on the material plate W2 but also partially with the material plate W1. Since the suction pad 35 at such a position has a problem when sucked, the suction pad 35 is kept in a suction stopped state.

As shown in each of these figures, the material plate W
When carrying out the product plate material W2 smaller than the one, one or both of the extensible frames 33b and 33c are contracted to narrow the interval between the suction pads, and to narrow the width of the suction pad array 36. Thereby, when placing the product plate material W2 in the product storage section 21 of the plate material storage device 2, the suction pad array 36
Can be placed without interfering with the plate material storage device main body 2a or the like composed of a frame or the like around the plate material storage device 2. That is, when placing the product plate material W2 on the product storage unit 21, the suction pad array 36 must be located at a position off the center of the product storage unit 21 in order to place the plurality of product plate materials W2. Therefore, if there is an obstacle that stands around the product storage unit 21 such as the plate material storage device main body 2a of the plate material storage device 2, interference with the suction pad array 36 is likely to occur. Such interference can be prevented by reducing the width of the suction pad array 36. Also, when the large material plate material W1 is transported, the suction pad array 36 is expanded,
By adsorbing over as wide a range as possible, stable conveyance can be performed.

Further, in the suction pad array 36, a part of the suction pads 35 _A and 35 _B is constituted by a group of small pads, and the suction paths 43 of the individual small pads 41 (FIG. 6 (A)).
Because are diaphragm 44 provided, be one hole, such as the product plate material W2 punch holes are formed, also, the negative pressure leakage problems if its hole in the suction pad 35 _A, 35 _B corresponding , The product plate material W2 can be reliably sucked and transported. Further, since the suction pads 35 _A and 35 _B composed of these small pad groups are concentratedly arranged on a part of the suction pad array 36, for example, FIG.
Small product plate material W2 as shown in FIGS.
However, it is possible to reliably suck and transport.

[0029] Since the portion of the suction pads 35 _B in the small pads concentrated arrangement portion 42 of the suction pads array 36, are to allow advance from the small pads concentrated arrangement unit 42 is attached further to the pivot arm 47, for example, FIG. 10 (C) and FIG.
In the case of 1 small product plate materials as shown in (A) W2, by advancing its expansion possible suction pads 35 _B between the turret 13 and the subhead 15, made adsorbed evenly, even more reliable adsorption I can do it. FIG. 11B
As shown in (2), even a small product plate material W2 that fits between the turret 13 and the sub head 15 and can be sucked by only one suction pad can be sucked. This advanceable suction pad 35
_B is retracted to the pad mounting frame 33 side when unnecessary, so that when the suction pad array 36 is moved, the advanced suction pad 35 _B is moved to the upper frame 14 of the plate processing machine 1.
Also, interference with the plate material storage device main body 2a and the like of the plate material storage device 2 is prevented.
