Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic scrap discharging device for a plate processing machine which automatically discharges scrap generated when a sheet-like work is processed by a plate processing machine such as a laser processing machine or a plasma processing machine. .

[0002]

2. Description of the Related Art Conventionally, when a sheet-like work is cut by a sheet material processing machine of this kind, a frame-shaped scrap called a residual frame is generated separately from the cut product.

[0003]

Conventionally, after cutting a product, an operator manually removes the scrap. However, when the process from loading, cutting, and unloading of a workpiece is to be automated, the scrap is unloaded. However, there was a problem that automation became difficult due to a bottleneck. The present invention has been made to improve the above-mentioned conventional problems, and has as its object to provide a scrap discharging apparatus of a sheet material processing machine capable of automatically discharging scrap generated after cutting of a product.

[0004]

According to the present invention, in order to achieve the above-mentioned object, a product, out of the products and scraps simultaneously discharged from the plate processing machine, is dropped to a product discharge conveyor on a work discharge side of the plate processing machine. A product discharge chute to be
A scrap receiving roller for passing scrap to the roller conveyor side is provided, and a scrap discharge chute for dropping scrap on the roller conveyor to a scrap receiving table is provided on the roller conveyor so as to be vertically movable.

[0005]

[Operation] With the above configuration, the scrap carried out together with the product from the plate processing machine can be sorted out from the product and automatically discharged to the scrap cradle. From the loading of the work to the continuous processing and unloading of the work Can be automated.

[0006]

[Embodiment] An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view of the apparatus, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof. In these figures, reference numeral 1 denotes a main body of the apparatus, which is installed adjacent to a work unloading side of a table 2a provided in a plate material processing machine 2. A product chute 4 for discharging a product 3 cut by the plate material processing machine 2 and a scrap receiving roller 5 for discharging a scrap 3a are provided on both sides of the main body 1 on the side of the plate material processing machine 2. I have. One of the scrap receiving rollers 5 is movable in the direction of the position indicated by the imaginary line in FIG. 1 in accordance with the size of the scrap 3a, and is provided with a free roller downstream of the scrap receiving roller 5. Roller conveyor 6 is installed.

[0007] Above the roller conveyor 6, a scrap conveying roller 7 is provided at the side of the roller conveyor 6 so as to swing freely. The scrap transporting roller 7 is rotated by a drive motor 8, and the scrap 3a on the roller conveyor 6 is indicated by an arrow A.
It can be transported in the direction.

On the other hand, the roller conveyor 6 is divided into a plurality of parts in the direction of arrow A, and a scrap discharge chute 10 is provided between the roller conveyors 6. The scrap discharge chute 10 has a rod shape that is slightly longer than the width of the roller conveyor 6, and the end opposite to the scrap transport roller 7 is hinged to the base 6 of the roller conveyor 6.
a. In addition, each scrap discharge chute 1
Below 0, a dump cylinder 13 that simultaneously rotates each scrap chute 10 upward via a link 12 is provided. In the figure, reference numeral 14 denotes a product carry-out conveyor for carrying out the product 3 discharged by the product chute 4;
Reference numeral 5 denotes a product receiver, and reference numeral 16 denotes a scrap receiver for collecting the scrap 3a discharged by the scrap discharge chute 10.

Next, the operation will be described. The product 3 cut by the plate processing machine 2 is carried out to the main body 1 side by a gripping device (not shown) of the plate processing machine 2 in a state of being accommodated in a frame-shaped scrap 3a. You. When passing through the product unloading chute 4, the product 3 falls out of the scrap 3 a, is placed on the product unloading conveyor 14 by the product unloading chute 4, and is transported to the product receiving table 15.

The scrap conveyor roller 7 swings from a standby position by a stop signal when the gripper device of the plate material processing machine 2 reaches a stroke end and stops while passing over the scrap receiving roller 5 to reach the roller conveyor 6. The scrap 3a descends while contacting the upper surface of the scrap 3a, and conveys the scrap 3a in the direction of arrow A with the rotation of the drive motor 8. When the scrap transport roller 7 is raised to the standby position by the scrap unloading completion signal, the dump cylinder 13 rotates each scrap discharge chute 10 upward through the link 12 about the hinge 11, and thus the roller conveyor is driven. The scrap 3a on the scraper 6 is transferred to a scrap receiving table 16 by the scrap discharge chute 10.
Is discharged to the side and collected in the scrap receiving table 16. The above operation is repeated each time the product 3 and the scrap 3a are simultaneously carried out from the plate processing machine 2, so that the product 3 and the scrap 3a can be carried out in a sorted state.

Incidentally, when six sheet-like workpieces are continuously processed by the plate material processing machine 2, the conventional method of manually discharging scraps is as follows: processing time 20 minutes × 6 sheets = 120 minutes scrap discharging time 5 minutes × 6 sheets = 30 minutes A total of 150 minutes was required, whereas in the embodiment of the present invention, processing time was 20 minutes × 6 sheets = 120 minutes Scrap discharge time 0.7 minutes × 6 sheets = 4.2 minutes , Which is a total of 124.2 minutes, which is a 17.2% reduction in time as compared with the related art. Also, one worker can take charge of a plurality of plate processing machines, so that labor can be saved.

[0012]

[Effects of the Invention] As described in detail above, the present invention can automatically sort out the scraps processed by the plate processing machine and carried out together with the products, and discharge the scraps to the plate processing machine. , The continuous processing and the unloading of the work can all be automated. In addition, compared to the conventional manual scrap discharge method, the cycle time can be greatly reduced, improving productivity and the scrap can be carried out in a sorted state, which reduces the man-hour required for the sorting work. I can plan.
