Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work-carrying-in positioning device, and more specifically, when the work is automatically carried into a plate material processing device one by one, two adjacent sides of the work are moved along the X-axis.
The present invention relates to a work-carrying-in positioning device that abuts against an axial positioning member and a Y-axis positioning member for positioning.

[0002]

2. Description of the Related Art Conventionally, in a turret punch press, for example, as a plate material processing apparatus, a work positioning device for positioning a work carried on a table at an origin position is known. As this work positioning device, for example, a work drawing-in clamp device known from Japanese Utility Model Publication No. 63-38040 is attached to the body frame of the plate material processing device. The workpiece is clamped by the workpiece retracting clamp device and the origin is positioned by retracting the workpiece in an oblique position.

[0003]

In the work retracting clamp as the conventional work positioning device described above, since the work is retracted obliquely to the origin position, the probability of origin positioning is poor.

Further, since the work pull-in clamp is fixedly provided on the main body frame, it cannot be moved. Therefore, even if the work clamp (positioning member in the Y-axis direction) of the plate material processing device is moved to the side opposite to the origin position and the distance from the origin position increases, the origin positioning probability is low. In this case, an auxiliary locator pin is provided between the origin position and the work clamp to deal with it.

In order to improve the above-mentioned problems, an object of the present invention is to make it possible to position the origin of a work at the origin position with a high probability irrespective of the shape of the work, and at the same time, to simplify the mechanism and to prevent failures. An object is to provide a small number of work-carry-in positioning devices.

[0006]

In order to achieve the above-mentioned object, the present invention sucks a work by a suction part provided in a movable work-carrying carriage and carries the work horizontally to a table of a plate material processing apparatus. Then, a workpiece carry-in positioning device for positioning the origin of the workpiece by abutting two adjacent sides of the workpiece to the X-axis direction positioning member and the Y-axis direction positioning member, respectively, wherein the suction portion is attached to the workpiece carrying carriage by the X-axis. An actuator for moving in the axial direction and the Y-axis direction is provided to construct a work loading positioning device.

[0007]

By adopting the workpiece loading / positioning device of the present invention, the workpiece is attracted by the suction portion to move the workpiece loading carriage, and the workpiece can be loaded to the vicinity of the origin position on the table in the plate material processing apparatus. Then, in the state where the work is sucked by only one of the suction parts, the Y-axis actuator is operated to move the suction part in the Y-axis direction so that one side of the work is abutted against the X-axis direction positioning member. At the same time, the X-axis actuator is operated to move the suction portion in the X-axis direction, and the other side of the work is abutted against the Y-axis direction positioning member, whereby the origin of the work is positioned.
