DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transporting a plate-like material from a material support device to a work processing machine such as a punch press,
The present invention relates to a work carry-in / carry-out system that carries out a semi-finished product having an appropriate number of product parts from a work processing machine to a semi-finished product support device.

[0002]

2. Description of the Related Art A conventional work loading / unloading system will be briefly described below.

That is, a material support device for supporting a plurality of plate-shaped materials is provided near the right side of a work processing machine such as a punch press, and the material is loaded into the work processing machine from this material support device at an appropriate position. A material loading device is provided. Further, near the right side of the work processing machine, a semi-finished product support device for supporting a semi-finished product having an appropriate number of product parts is provided in front of and behind the material support device. A semi-finished product unloading device for unloading a semi-finished product to the semi-finished product support device is provided. And a marking head is provided in the vicinity of the processing portion of the work processing machine,
The marking head is for marking predetermined printing information on the product part of the semi-finished product in order to distinguish the product part itself of the semi-finished product or a subsequent process.

Therefore, the material is carried into the work processing machine from the material support device by the material carrying device. Then, the workpiece processing machine performs various types of processing on the material. Thus, the material can be formed into a semi-finished product having an appropriate number of product parts.

After performing various processes on the workpiece, the semi-finished product is placed on the marking head in the X-axis direction,
By moving in the Y-axis direction, it is positioned relatively vertically (directly above) an appropriate product part in the semi-finished product.

Any of a mounting type and a laser irradiation type may be used. The tip of the marking head 79 is moved up and down by operation of a lifting actuator (not shown).

Next, the operation of the embodiment of the present invention will be described.

Under the condition that the upper surface of the material W is sucked by the plurality of vacuum pads 37, the carry-in slider 31 is moved in the X-axis direction by the operation of the self-propelled motor, and the punch press is performed from the position above the material supporting device 19. 3 to the upper position. Then, the suction state of the plurality of vacuum pads 37 is released. Thus, the material W can be carried into the punch press 3.

After loading the material W into the punch press 3,
The workpiece is moved to the processing part 7 by the work positioning device 9
The desired processing is performed on the material by the processing unit 7 while positioning in the axial direction and the Y-axis direction. Thereby, the material W can be formed into a semi-finished product WA having an appropriate number of product parts G.

After performing the desired processing on the material W, the movable table 1 is integrated with the work positioning device 9.
The semi-finished product WA is positioned below the X-axis guide member 61 by moving the members 3 and 15 in the Y-axis direction. Next, the right end of the semi-finished product WA is clamped by a plurality of clampers 71,
The semi-finished product WA is delivered from the work positioning device 9 to the plurality of clamps 71. Then, the unloading X-axis servomotor 65
By moving the unloading slider 63 in the X-axis direction along the X-axis guide member 61 by the operation of the above, the unloading slider 63 is moved from the position above the punch press 3 to the position above the semi-finished product support device 41, and the clamped state of the plurality of clampers 71 To release. Thus, the semi-finished product WA can be carried out from the punch press 1 to the slat conveyor 47 in a closed state.

After the semi-finished product WA is carried out to the slat conveyor 47 in the semi-finished product support device 41, the clamper supporting member 69 is raised by the operation of the lifting cylinder. next,
The marking head 79 is moved in the X-axis direction integrally with the unloading slider 63 by the operation of the unloading X-axis servo motor 65, and the marking head 79 is moved along the Y-axis guide member 83 by the operation of the marking Y-axis servo motor 81.
