[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product unloading method and a device for unloading a product processed by a processing machine such as a laser processing machine or a punch press.

[0002]

2. Description of the Related Art Conventionally, a compound processing machine having a laser processing machine and a hydraulic punch press has been known. In the laser processing machine of this combined processing machine, the work is moved along the X axis and the Y axis, the laser processing head is moved only along the Z axis, and the work is fixed without moving along the X axis and the Y axis. Also,
In the hydraulic punch press, the work is moved to the X and Y axes for punching.

The product processed by this combined machine is carried out by a takeout loader equipped with a vacuum pad, a magnet block and a work clamp.

In another laser processing machine, the laser processing head is moved in the Y-axis and Z-axis directions, and the processing table on which the workpiece is fixed is moved in the X-axis direction. In this laser processing machine, there is a pallet that fits the maximum processing work size, and the work is supported on this pallet during laser processing, and when the processing for one sheet is completed, the pallet is exchanged for each pallet, for example. Kaihei 4-3

[0005]

By the way, when the product processed by the above-mentioned conventional multi-tasking machine is carried out by the takeout loader, the takeout loader picks up the product depending on the size of the product and the plate cutting position. You need to control where you go numerically. In addition, product drilling,
Since the outer circumference cutting and the carrying-out operation are performed one by one, the tact time becomes long.

Further, in the conventional one for exchanging each pallet, since the machining table moves, it is difficult to take out the product, and after the machining for one sheet is completed, the pallet is exchanged, which is a large-scale device. I will end up.

The object of the present invention is to facilitate the separation of the residual material from the product in a short time, to carry out the product regardless of the shape and size of the product, and to use not only the coil material, An object of the present invention is to provide a method and an apparatus for carrying out a product in a processing machine that can be applied to sketch materials and standard length materials.

[0008]

In order to achieve the above object, a method for carrying out a product in a processing machine according to a first aspect of the present invention is such that a work clamped by a work clamp is supported by a work table raised from below. After processing the plate material on the work piece in the raised state, while the processed product is supported by the work table, lower the work table to the carry-out position and rotate the work support member on the work table to rotate the work piece. It is characterized in that the product can be carried out to a carry-out table provided beside the table.

According to a second aspect of the present invention, there is provided a method of unloading a product in a processing machine according to the first aspect of the present invention, in which the work clamp is vibrated after the work is processed into a plate material. It is a feature.

According to a third aspect of the present invention, there is provided a product carry-out device for a processing machine, wherein a workpiece clamp for clamping the workpiece at the processing position in the processing machine, a support position for supporting the workpiece at the processing position, and the processed product. It is composed of a vertically movable and freely rotatable work table that is selected as a carry-out position that allows the work table to be carried out, and a carry-out table that is provided beside the work table and that has its upper surface flush with the carry-out position of the work table. It is characterized by that.

According to a fourth aspect of the present invention, there is provided a product unloading device for a processing machine according to the third aspect of the present invention, wherein the work clamp is provided with a vibration device.

In the method and the apparatus for carrying out the product in the processing machine according to the first to fourth aspects of the invention, the work to be processed is clamped by the work clamp at the processing position of the processing machine. Moreover, the work table is raised to the supporting position to support the lower surface of the work. In this state, the work is subjected to processing such as cutting. After the cutting process is performed, when the vibration device provided in the work clamp is operated, the work and the product vibrate through the work clamp, and the product is separated from the work.

Since the product separated from the work is supported by the work table, the product is carried out to the carry-out table by lowering the work table to the carry-out position and then rotating the work supporting member on the work table. Furthermore, it is carried out to the outside.

Thus, the residual material and the product can be easily separated in a short time and can be easily carried out regardless of the shape and size of the product.
