Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for separating and accumulating products and skeletons in a work conveying / accumulating apparatus of a plate material processing machine such as a laser beam machine or a punch press.

[0002]

2. Description of the Related Art When a workpiece is processed by a laser processing machine and the product is transferred to a stacking device in a semi-finished state without being separated, even in the case of micro-jointless processing, that is, the contour of the product is completely cut. Even though the gap between the outer circumference of the product and the inner circumference of the skeleton is extremely small, the product and the skeleton are difficult to separate due to the frictional resistance of the thickness of the work, and this tendency is strong especially in the work of taking large numbers of small products, It is necessary to forcibly perform a separating operation. As shown in Japanese Patent Application No. 8-31112, both ends of the work placed on the pipe roller conveyor are clamped by a clamp device, and the work is placed on the pipe roller conveyor. Vibration is applied to the work in a slightly floating state, or the work is bent to separate the small product and the skeleton from the work, and the separated small product and the skeleton are each separated into a dedicated integrated cart. The it is common is the product.

[0003]

However, in the above-mentioned conventional example, in the case of a work having a small thickness, the product and the skeleton are separated, the product is placed on a pipe roller, and only the skeleton is clamped by the clamp device. When lifted,
Because the thickness of the work is thin and only the opposite ends are sandwiched, and in the case of a skeleton, the product is separated and the part is hollow, it is easy to bend, and therefore easily detached from the clamp device. There is a problem that the product is dropped on the product placed on the pipe roller first, disturbing the product accumulation, and the accumulation operation cannot be performed.

The present invention has been made by paying attention to the above points, and is capable of running simultaneously with a fork lifter serving as a holding means, provided with a suction unit for reliably sucking and holding the skeleton after separating the product and the skeleton. It is an object of the present invention to provide a method of separating and integrating a product having a simple mechanism and a skeleton.

It has a function to synchronize the movement of 0.

The length and width of the fork 5 of the fork lifter F can be freely entered and retracted according to the installation state of the work supporting blade 4 of the plate material processing machine 1 and the pipe roller 8 of the pipe roller conveyor 7. It is determined to be.

Reference numeral 11 denotes a suction head (vacuum pad or electromagnet); 11s, stretching; 11a, an elevating cylinder; 11b, a traveling means; which constitutes a suction unit K;
Numeral 1 is suspended and arranged on the stretch 11s in a grid of plural rows and plural columns.

The traveling means 11b of the suction unit K is connected to the traveling means 5b of the fork lifter F by a coupler R, and both can travel horizontally at the same time.

The operation will be described based on the above configuration.

FIG. 4 shows a state of a separating operation for separating the product Ws and the skeleton Wx from the work W. The work W is held by the fork 5 of the fork lifter F and provided on the pinion P provided on the traveling means 5b. The work W is transported by the action of the rack 6 a attached to the guide rail 6, stops at a predetermined position, and firstly, the work W is placed on the pipe roller 8 of the pipe roller conveyor 7, and then the work W is transferred to the pipe roller 8. While placed on the top, the fork 5 of the fork lifter F is once pushed down below the pipe roller 8 by the lowering action of the elevating cylinder 5a, moves horizontally horizontally to retreat, and stops at a predetermined position.
At this time, the traveling means 5b and 11b of the fork lifter F and the suction unit K are connected by the coupler R, so that the suction unit K moves horizontally with the movement of the fork lifter F, and the pipe rollers 8 of the pipe roller conveyor 7 are moved. The suction head (vacuum pad or electromagnet) 11 suspended at the upper predetermined position and suspended on the stretch 11s by the lowering action of the lifting / lowering cylinder 11a is pushed down together with the stretch 11s, and the tip of the suction head (vacuum pad or electromagnet) 11 is moved. Abuts on the upper surface of the workpiece W, stops, and sucks only the skeleton Wx (vacuum pad or electromagnet).
The suction head (vacuum pad or electromagnet) 11 of the suction unit K holding only the skeleton Wx while maintaining this state is stretched 11s by the lifting action of the lifting cylinder 11a. And stops at a predetermined position, but the skeleton Wx is separated from the work W and only the product Ws is placed on the pipe roller 8.
And the workpieces W are aligned and accumulated on the dedicated accumulation cart 9. Following this operation, the suction head (vacuum pad or electromagnet) 11 is moved through the lifting cylinder 11a and the stretch 11s provided in the suction unit K.
