Abstract

A manufacturing method of a bag body that has a bag-shaped member made of an elastic and airtight material, and a granular substance filled inside of the bag-shaped member, includes a step of preparing a core for forming the bag-shaped member, by hardening the granular substance; a step of forming the bag-shaped member by forming a covering made of the elastic and airtight material around the core; and a step of breaking up the core that is inside of the bag-shaped member.

Description

technical field [0001] The invention relates to a method of manufacturing a pouch, such as a member forming a tip portion of a gripping device, which is formed by filling a pouch-shaped member with a granulated substance. An example in which the bag is applied to the contact portion, ie, the member forming the tip portion of the gripping device, is described below. However, the application range of the bag is not limited thereto. Background technique [0002] Gripping devices for gripping workpieces have been developed that can easily grip workpieces of various shapes without replacing tip portions and the like. Also, in this type of gripping device, a reliable gripping state can be ensured by deforming the contact portion, which is the portion that directly contacts the workpiece, so as to conform to the shape of the workpiece. The contact portion can take two forms with a single member, namely, a form in which the shape of the contact portion can be flexibly deformed, an...
