DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet unloading apparatus for unloading a product sheet on a product table separated from a sheet processing machine by a processing head.

[0002]

2. Description of the Related Art As shown in FIG. 5, a turret punch press is formed by a main punch at a predetermined processing position A from a material plate W1 to a product plate W.
In some cases, after the outer periphery of the workpiece 2 is connected to the workpiece W1, the product workpiece W2 is separated from the workpiece W1 by a sub-punch at another processing position B. In this case, for example, a suction unloader is used as a unit for unloading the product plate material W2 on the separated product table 50.

However, since the suction unloader is so large that it can carry out even a relatively large product plate W2, it is not possible to approach the vicinity of the sub-punch, and for example, a small product plate W2 of 100 mm × 100 mm square or less.
Could not be carried out. Even if the unloader can be unloaded, the unloader has to reciprocate along a long unloading path to unload the small product plate material W2.

Therefore, as shown in FIG. 5, it has been proposed to arrange a shooter having an opening 51 which can be opened and closed near a processing position B corresponding to the sub-punch in the product table 50 below the product table 50. (Japanese Patent Publication No. 4-72621). However, since a mechanism such as a ball screw and a guide for moving the table is arranged below the product table 50 in a punch press of a turret type or the like, the carry-out path by the shooter is provided below the product table 50. Is often difficult.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem, and a shooter cannot be provided under a product table even if a normal unloader is a small product plate that cannot be brought close to the vicinity of a processing head. It is an object of the present invention to provide a sheet unloading device that can easily unload a product sheet even in a sheet processing machine.

[0006]

Things. According to this configuration, the product plate material cut off on the product table is picked up by the pick-up means and carried out to a predetermined unloading position. From the unloading position, the unloading means further transfers the product plate material via the path below the product table to the outside of the machine. To be carried out. In this case, since the pickup means can switch the position between the adjacent position of the processing head and the unloading position, the product plate material is small, and it is located near the processing head so that a normal unloader is not accessible. Even if there is, it can be carried out. Further, since the pickup means only needs to transport the product plate from the position adjacent to the processing head to the transport device that unloads the product via the path below the product table, the moving range can be short, and therefore, the small product Even in the case where a large number of plate materials are processed, useless movement time does not occur, and it is possible to carry out efficiently. Furthermore, since the unloading means receives the product plate material unloaded by the pickup means and unloads it outside the machine, the degree of freedom in designing the unloading path is high, and a ball screw or guide is provided below the product table. In some cases, it is possible to design a carry-out route while avoiding those obstacles.

In the above configuration, the product table may be configured to be movable, and the path of the unloading means may be configured to start from the predetermined position provided in a space opened by the movement of the product table. . Thereby, a small product plate can be carried out of the machine from the product table without forming a special shooter or the like on the product table.

In the above-mentioned configuration, the pickup means may have a holding portion capable of holding a product plate material, and the holding portion may be able to sunk into a space below an object around the processing head. According to this configuration, it is possible to approach the adjacent position of the processing head on the product table. For this reason, it is possible to carry out a smaller product plate material, and the degree of freedom in how to set the final separation position on the outer periphery of the product for convenience in carrying out the product is increased.

A description will now be given of the operation of transporting the sheet material in the sheet material processing equipment having the above-described configuration. The plate material transfer device 3 picks the material plate materials W1 loaded in the material storage section 23 of the plate material storage device 2 one by one and carries them into a predetermined position on the product table 5 of the plate material processing machine 1.

In the plate processing machine 1, various punching processes are performed on the raw plate W1 at the punch position P by the main processing head 6. When the product plate W2 is cut out from the material plate W1, the outer periphery of the product plate W2 is applied to the material plate W1 by the main processing head 6. At this time, for the convenience of feeding the material plate W1 by the plate feeder 7, the main processing head 6 processes the product plate W2 to a state where the product plate W2 is partially connected to the material plate W1. To separate. Therefore, the cut product plate material W2 is always located near the sub processing head 15. When the product sheet material W2 thus separated is larger than a predetermined size (for example, 100 mm × 100 mm square), it is carried out by the sheet material transport device 3. That is, the product plate material W2 is
The sheet material is sucked by the suction pad 28 of the sheet material transport device 3 and is carried out to the product storage section 21 of the sheet material storage device 2.

When the product plate material W2 separated by the sub-processing head 15 is smaller than a predetermined dimension, the plate material transporting device 3 uses the sub-processing head 15 and the sub-processing head covering portion of the machine cover 16 as a peripheral object. The pad support 26 cannot enter the lower space. For this reason, the sheet material cannot be unloaded by the plate material transporting device 3, and is unloaded by the small piece plate material unloading device 30.

At the time of unloading, the pickup means 3 which has been waiting at a predetermined standby position (for example, unloading position A).
The first holding portion 35 is turned by the drive of the turning drive means 37 and sinks into the sub-working head 15 or a space below the adjacent position. Next, the holding unit 35 is slightly lowered by the driving of the lifting / lowering driving unit 36, and the suction pad 40 of the holding unit 35 is moved.
Thereby, the product plate material W2 on the product table 5 is sucked.
The suction pad 40 is a collection of a large number of small suction pads 40a, and is connected to a vacuum source via a throttle path. Therefore, suction can be performed even when a part of the suction pad 40 protrudes from the product plate material W2. . After the suction, the lifting drive means 3
6, the holding portion 35 slightly rises, and the product plate material W
2 is picked up. Next, the position of the holding unit 35 is switched from the position adjacent to the sub-processing head 15 to the unloading position A by the reverse turning drive of the turning drive unit 37. Here, the suction of the suction pad 40 is released, and the product plate material W2 held by the holding unit 35 is transferred onto the start end of the first stage conveyor 43 of the unloading means 42. At this time, it is necessary that the unloading position A is not covered with the movable table 5c. However, in normal processing, when the product plate material W2 is separated, the unloading position A is at a front and rear position where the movable table 5c is not covered. . The product plate material W2 placed on the first stage conveyor 43 of the unloading means 42 is moved from the first stage conveyor 43 to the second stage.
It is transferred to and transported on the stage conveyor 44. That is,
The product plate material W2 is carried out to the front of the plate material processing machine 1 along an L-shaped path passing from below the right rear end of the product table 5 to below the auxiliary table 4, and is collected in the product collection box 45.

Since the product plate material W2 is carried out along such a path, a shooter cannot be provided below the product table 5 due to a ball screw, a guide or the like constituting a moving mechanism of the product table 5. Even if
The product plate material W2 can be easily carried out of the machine. In addition, since the pickup means 31 capable of switching the position between the position adjacent to the sub-processing head 15 and the unloading position A is used and the sheet is transferred to the transfer means 42 including a conveyor, the unloading and unloading can be performed by the loading and unloading plate transfer apparatus 3. Even a small product plate W2 can be carried out, and even when a large number of small product plates W2 are carried out, the product can be efficiently carried out.

In the embodiment, the sub machining head 1
5 has been described, the plate processing machine 1 does not have the sub head 15 and the main processing head 6
May be used to separate the product plate material W2,
In this case, the position of the pickup means 31 can be switched between a position adjacent to the main processing head 6 and a predetermined unloading position A.
