In this state, by irradiating the laser beam LB oscillated by the laser oscillator 23 from the laser processing head 21 to the workpiece W, laser processing is performed on the workpiece W.

Brackets 25 and 27 are attached to the front and rear of the upper left wall of the portal frame 3. A drive sprocket 29 and a driven sprocket 31 of the carry-out conveyor 28 are rotatably supported below the brackets 25 and 27, respectively. Moreover, a chain 33 is wound around the driving sprocket 29 and the driven sprocket 31. The bracket 25 is provided with a drive motor 35 for drivingly rotating the drive sprocket 29.

With the above configuration, when the drive motor 35 is driven, the drive sprocket 29 is rotated, so that the chain 33 is rotated.

The chain 33 is provided with a vacuum pad device 39 having a plurality of vacuum pads 37 which can be moved up and down by, for example, air cylinders as a plurality of product suction means at appropriate intervals. Therefore, the chain 33
Is rotated, the respective vacuum pad devices 39 are rotated.

A product sorting conveyor 41 is provided below the bracket 25. More specifically, FIG.
As shown in FIG. 2, a drive pulley 43 and a driven pulley 45 are provided on both left and right sides, for example.
A belt 47 is wound around 3 and the driven pulley 45. A drive motor 49 is connected to the rotation shaft of the drive pulley 43. A plurality of sorting boxes 51 are provided on the belt 47 at appropriate intervals in the left-right direction. Also,
In FIG. 1, a work loading / unloading device 53 that supplies a work or unloads a skeleton is arranged beside the right side table 11.

With the above configuration, the work W to be machined is carried from the work carrying-in / out device 53 onto the side table 11 and the center table 9 and clamped by the work clamp 15. The desired position of the work W clamped by the work clamp 15 is moved and positioned at the punching position K, and the work is punched by the cooperation of the punch P and the die D.

Next, after the work W is punched, the work W is moved in the X-axis direction by the laser processing head 21.

The laser-cut and cut product is supplied to the vacuum pad 37 of the vacuum pad device 39.
Is lifted up after the product is adsorbed on the vacuum pad 37. The vacuum pad 37 having adsorbed the product is moved downward by moving the chain 33 downward in FIG. 1, and the next product is adsorbed by the next vacuum pad 37.

The products cut one after another in this way are sucked by the vacuum pad 37 and run downward in FIG. 1 to reach the position immediately above the product sorting conveyor 41. Sorting box 5 by type
It will be sorted into one and carried out. The skeleton is carried out to the outside by the work carrying-in / out device 53.

The processed products are successively adsorbed by the vacuum pad 37 and are carried out by the carry-out conveyor 28, so that the carry-out time of each product is short.
In addition, it is carried out without any damage, and the operation rate of the machine and the product accuracy can be improved.

The processed product is stored in a sorting box 51 provided on a product sorting conveyor 41 in a product size,
They can be sorted out for each type and transported.

Further, since the carry-out conveyor 28 is provided so as to extend in the front-rear direction (vertical direction in FIG. 1) of the left side table 11 of the processing tables, products can be easily carried out and carried out. Conveyor 2
8 can be easily assembled.

This product unloading device has been described by taking the punch and laser compound machine 1 as an example of a plate material processing machine. However, a laser processing machine or a punch processing machine can be particularly effectively used.

The present invention is not limited to the above-described embodiments, but can be embodied in other forms by making appropriate changes. Although the vacuum pad device 39 has been described as an example of the product suction means, a magnet device that suctions the product with a magnet may be used. Further, as the laser processing machine, the laser processing head 21 may be fixed or biaxially moved in addition to the one-axis movement. Although the laser processing position L has been described as being located at a position offset in the Y-axis direction with respect to the punch processing position K, the laser processing position L may be at a position offset in the X-axis direction.

The direction in which the processed product is carried in may be not only the Y-axis direction but also the X-axis direction. That is, the unloading conveyor 28 may be provided to extend in the X-axis direction. The work loading / unloading device 53 may be manually operated or automatically operated using an external device.

[0039]

As can be understood from the above embodiments of the present invention, according to the first aspect of the present invention, the desired position of the work placed on the processing table is moved to the processing position and positioned. Processing is performed. The product on which the plate material is processed is lifted after the product suction means provided on the unloading conveyor extending in one direction at a position above the processing table near the processing position is lowered and suctioned. Next, when the next product is carried out, the carry-out conveyor is run and the product is sucked by the next product suction means.

The products processed in this manner are successively sucked by the product suction means one after another, and when the product suction means reaches the other end of the carry-out conveyor, the product is released from the product suction means and carried out.

Since the processed products are successively sucked by the product sucking means and the carry-out conveyor is run and carried out, the carry-out time of each product is shortened, and the products can be carried out without being damaged. Therefore, the operation rate of the machine and the product accuracy can be improved.

According to the second aspect of the present invention, the processed products are successively sucked by the product suction means and the carry-out conveyor is run, and when the sucked products reach the other end of the carry-out conveyor, the carry-out conveyor is moved. Can be sorted out according to size and type into a plurality of sorting boxes on a product sorting conveyor provided below the other end.

According to the third aspect of the present invention, by using a laser processing machine, a punch laser combined processing machine or a punch processing machine as a plate processing machine, the product unloading device can be particularly effectively exerted.

According to the fourth aspect of the present invention, by providing the carry-out conveyor extending in the front-rear direction of the processing table, the processed product can be easily discharged and the take-out conveyor can be easily assembled. It can be carried out.
