TECHNICAL FIELD

The present invention relates to a binding device, and relates to a plier-type binding device that binds an object to be bound with binding tape stretched between a pair of arms.

BACKGROUND ART

In a so-called plier-type binding device, if a pair of gripped arms is slightly returned at a time when binding tape is stretched between the pair of arms, in conjunction with this, a tape holding plate of a tape retaining mechanism moves forward. Then, an end portion of the binding tape drawn from a tape reel is retained by a tape receiving plate and the tape holding plate (e.g., refer to Patent Literature 1). In such a binding device, in a case where binding tape including a biodegradable material as a base material (hereinafter referred to as “biodegradable tape”) is used, the biodegradable tape may be damaged (torn) by causing a pointed head tip end portion of the tape holding plate to enter, because the biodegradable tape is more fragile than ordinary binding tape including a non-biodegradable material as a base material (hereinafter referred to as “non-biodegradable tape”).

SUMMARY OF INVENTION

Technical Problem

An object of the present invention is to provide a binding device that prevents damage to binding tape including a biodegradable material as a base material.

Solution to Problem

The present invention relates to a binding device including a pair of arms that rotates about a fulcrum by a pair of grips being tightly gripped, a tape supporting mechanism that supports binding tape drawably, a tape feeding mechanism that feeds the binding tape drawn from the tape supporting mechanism, a tape retaining mechanism that retains an end portion of the binding tape fed from the tape feeding mechanism, and a tape press-bonding mechanism that press-bonds joining portions of the binding tape fed from the tape feeding mechanism. The binding device causes the binding tape stretched between the pair of arms to bind an object to be bound attracted between the pair of arms, in which the tape retaining mechanism includes an operation plate that is provided on one arm, a movable plate that is provided on another arm and operated by the operation plate, a tape holding plate that is provided on the other arm and operates in conjunction with the movable plate, and a tape receiving plate that is provided on the other arm. The tape retaining mechanism is configured to retain, between the tape receiving plate and the tape holding plate, the end portion of the binding tape fed from the tape feeding mechanism by the tape receiving plate receiving a tip end portion of the tape holding plate, and the tape receiving plate is formed by an elastic body.

Advantageous Effects of Invention

According to the present invention, it is possible to provide a binding device that prevents damage to binding tape including a biodegradable material as a base material.
