Problems solved by technology

When holding such a bulk workpiece with a multi-fingered hand, the workpiece can be held by one set of fingers while the other set of fingers interferes with other workpieces without overlapping other workpieces on the target workpiece to be held. The target workpiece cannot be held, and as a result, there is a problem that the target workpiece falls

Abstract

It is an object of the present invention to provide a workpiece holding method which enables a workpiece to be held when a multi-fingered hand is used to grasp the workpiece that is in an untidy heap, even if a target workpiece is subject to interference from another workpiece, and thereby the method enhances the success rate for holding the workpiece. A workpiece holding method, when two holding devices (first to fourth fingers F1 to F4) are used to hold a workpiece (reinforcement W), including a unilateral holding process of inserting a first holding device (the first finger F1 and the second finger F2) at one holding device insert position (region A) to hold and lift a workpiece-to-be-held (reinforcement-to-be-held T) in a state where the workpiece-to-be-held has no interference from any other workpieces at the region A, and a bilateral holding process of inserting a second holding device (the third finger F3 and the fourth finger F4) around (region D) the workpiece-to-be-held lifted by the first holding device, to hold the workpiece-to-be-held.

Description

technical field [0001] The present invention relates to a method of holding a workpiece, and more particularly to a method of holding a plurality of workpieces in a bulk state using two holding devices. Background technique [0002] Conventionally, mechanical products such as automobiles are manufactured by combining multiple parts. Specifically, for example, a plurality of robots are arranged in a production line to transport vehicle bodies and the like along the production line, and the workpieces (assembled parts) to be mounted on the vehicles are stored in box-shaped hoppers (trays), and the hoppers are placed on the supply for each robot. Each robot uses the fingers of the hand provided at its front end to hold the workpiece in the hopper and install it with respect to the automobile body conveyed in the production line, or to hold each workpiece in a plurality of hoppers, and make it relative to the next machine. In preparation for the assembly process of the motor v...
