Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is designed to separate a product from a plate material after the product is processed to connect the product with a small connecting portion at a corner so that the product is not separated from the plate material by a punch press during processing. Product separation method and apparatus therefor.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 8, for example, when a product G is punched from a plate material W by a turret punch press, the plate material W is punched.
Therefore, there is known a method (hereinafter, referred to as a micro joint) for processing the product G without punching the product G, leaving a small joint J (micro joint) of, for example, about 0.1 to 0.15 mm in each corner C. There is.

The following three methods are known as methods for separating the microjoined product G from the plate material W.

(A) The product G is separated by tapping the center of the product G with a hammer.

(B) An operator holds the end portion of the plate material W by hand and shakes it to drop the product G from the material W to separate the product G (however, for a thin plate having a plate thickness of about 0.5 mm).

(C) The plate material W is lifted by a crane and then dropped, and the product G is separated from the plate material W by the impact at that time (in the case of a thick plate).

[0007]

By the way, in each of the above-mentioned conventional separation methods, an operator intervenes, which imposes a heavy burden on the operator and is dangerous. Further, although the processing time in the NC turret punch press is greatly shortened, it takes time to separate the micro joint part J.

Furthermore, when the product G is separated from the plate material W,
For example, burrs may be generated on each micro joint portion J, or other scratches may be attached to the product G.

Since the separation is done manually, it is difficult to handle if it is a standard length material. Therefore, it is often cut into an appropriate size and then microjoined. Therefore, there is a problem that the number of cutting steps increases.

In order to improve the above-mentioned problems, an object of the present invention is to automatically separate a product from a plate material without manual work, to shorten the separation time for separation, and to make a burr on the product. It is intended to provide a product separation method and an apparatus therefor which are prevented from being scratched.

[0011]

In order to achieve the above object, the present invention processes a product by connecting a corner portion with a small connecting portion so as not to be separated from a plate material by a punch press during processing. The product separating method is characterized in that the plate material is conveyed to a product separating device provided in the vicinity of the punch press, and the product is separated from the plate material in the product separating device.

Further, the present invention is a product separating device provided in the vicinity of a punch press for processing a product so as to connect a corner portion with a small connecting portion so as not to be separated from a plate material during processing. A work transfer device that clamps and transfers the plate material from the work transfer device, and a reciprocating work support device that supports a plurality of support rollers having separate areas for separating the product from the plate material transferred by the work transfer device, A vertically movable and rotatable separator device having a plurality of separating members for separating the product from the plate material in the separate area is configured.

In the product separating device, the work supporting device is an endless member, the work transporting device is composed of a guide member which can be expanded and contracted in two stages, and the work supporting device having the separate area. It is preferable that a product table on which the product separated from the plate material is placed is provided at a lower position, and further, an end material cutting machine is arranged on the side opposite to the punch press side of the work supporting device. is there.

[0014]

By using the product separating method and apparatus of the present invention, the product is first processed by the punch press so that the corner portions are connected by the small connecting portions so as not to be separated from the plate material during processing. Then, the plate material is clamped from the punch press to a product separating device provided in the vicinity of the punch press and is conveyed by the work conveying device. And the plate material is supported by a plurality of support rollers in the work supporting device,
The products connected by the small connecting portion are positioned in the separate area. Next, by lowering and rotating the separator device, the product is separated from the small connecting portion by pressing the product with the plurality of separating members, and the product is placed on the product table.

In this way, each product is separated from the small connecting portion of the plate material, and each product is placed on the product table.
Moreover, the scrap material is cut and discharged by a scrap material cutting machine provided on the opposite side of the work supporting device from the punch press.
