Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product unloading apparatus for unloading a processed product to an unloading side of a work processing machine.

[0002]

2. Description of the Related Art A conventional product unloading device for unloading a processed product to an unloading side of a workpiece processing machine will be briefly described.

A guide rail is provided on the unloading side of the work processing machine, and the guide rail extends in the unloading direction, and a part of the guide rail is located above the work processing machine. An unloading slider is provided on the guide rail so as to be able to reciprocate in the unloading direction, and the unloading slider is provided with a plurality of unloading work clampers for clamping a clamped portion of the product.

[0004] Therefore, the carry-out slider is moved in the carry-out direction to approach the processed product. As a result, all the unloading clampers required for clamping are positioned at the clamping position (the position where the clamped portion of the product can be clamped). Then, the clamped portion of the product is clamped by all the unloading clampers necessary for the clamp, and the unloading slider is moved back in the unloading direction, so that the product can be unloaded to the unloading side of the work processing machine.

[0005]

By the way, when the portion to be clamped of the product is unprocessed, the unloading slider is moved forward in the unloading direction to approach the product so that all unloading clampers necessary for clamping are removed. Although it can be positioned at the clamp position, if notches are machined in the clamped part of the product, all the unloading clampers required for clamping are located at the clamp position even if the unloading slider is moved closer to the product. I can't let it go. Therefore, in the latter case, the clamp portion of the product cannot be clamped by the required number of unloading clampers, and it is difficult to unload the product to the unloading side.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to reliably discharge a product irrespective of the shape of a clamped portion of the product.

[0007]

A reciprocating cylinder for reciprocating each unloading clamper in the unloading direction with respect to the unloading slider is provided.

According to the first aspect of the present invention,
The unloading slider is moved in the unloading direction to approach the processed product. Thus, when the clamped portion of the product is unprocessed, all the unloading clampers required for clamping can be positioned at the clamping position.

On the other hand, when a notch is machined in the clamped portion of the product, even if the carry-out slider is brought close to the product, a part of the carry-out clampers of all the carry-out clampers necessary for clamping are moved to the clamp position. Although it can be positioned, it is not possible to position all the unloading clampers required for the clamp at the clamp position. Therefore, the remaining appropriate number of unloading clampers are moved forward in the unloading direction with respect to the slider by the operation of the corresponding reciprocating cylinder, and are positioned at the clamp position.

[0010] Further, if the unloading clamper cannot be positioned at the clamp position due to reasons such as avoiding interference of the unloading slider with the processing portion even if the unloading slider is moved in the unloading direction, the unloading slider is not provided. Then, the appropriate number of unloading clampers required for the clamp are moved forward in the unloading direction by the operation of the corresponding reciprocating cylinder, and are positioned at the clamp position.

After the unloading clamper required for the clamp is located at the clamp position, the portion to be clamped of the plate is clamped by the unloading clamper. Then, by moving the unloading slider back in the unloading direction, the product can be unloaded to the unloading side of the workpiece processing machine.

According to the second aspect of the present invention, in addition to the matters specified in the first aspect of the present invention, it is detected that each of the unloading clampers is located at a clamp position where the clamped portion of the product can be clamped. A sensor is provided, and the reciprocating cylinder can be controlled so that the forward movement of the corresponding unloading clamper in the unloading direction is stopped when each sensor performs a predetermined detection. I do.

According to the invention specifying matter of claim 2,
In addition to the operation according to the first aspect of the present invention, when the unloading clamper is moved forward in the unloading direction with respect to the slider by the operation of the corresponding reciprocating cylinder and is positioned at the clamp position, a predetermined sensor is provided by the corresponding sensor. Is detected, and the corresponding reciprocating cylinder is controlled such that the forward movement of the corresponding unloading clamper in the unloading direction is stopped.
