Binding facility, wire feeding mechanism and binding machine

Abstract

A binding facility includes: a binding mechanism configured to bind a binding target with a plurality of wires; a reel accommodation part in which a plurality of reels each having one wire wound thereon are accommodated; and a wire feeding mechanism configured to feed each wire from the plurality of reels accommodated in the reel accommodation part to the binding mechanism.

What is claimed is: 
     
         1 . A binding facility comprising:
 a binding mechanism configured to bind a binding target with a wire;   a wire pullback mechanism configured to feed the wire fed in a first direction and wound around the binding target by the binding mechanism in a second direction opposite to the first direction to wind the wire on the binding target;   a reel accommodation part in which a reel having the wire wound thereon is accommodated; and   a wire feeding mechanism configured to feed the wire from the reel accommodated in the reel accommodation part to the binding mechanism,   wherein the wire feeding mechanism includes a wire pullout mechanism configured to pull out the wire from the reel, and   wherein the wire pullout mechanism is provided between the wire pullback mechanism and the reel.   
     
     
         2 . The binding facility according to  claim 1 , wherein the wire feeding mechanism includes a load applying unit configured to apply a load in a feeding direction of the wire, the load applying unit provided on at least one of an upstream side and a downstream side of the wire pullout mechanism with respect to the first direction, and
 wherein the load applying unit makes a load, which is applied to the wire on the upstream side of the wire pullout mechanism, greater than a load, which is applied to the wire on the downstream side of the wire pullout mechanism.   
     
     
         3 . The binding facility according to  claim 2 , wherein the wire feeding mechanism is configured so that, when the wire is fed in the second direction on the downstream side of the wire pullout mechanism and the load applied to the wire on the downstream side of the wire pullout mechanism becomes greater than the load applied to the wire on the upstream side of the wire pullout mechanism, the wire is fed in the first direction on the upstream side of the wire pullout mechanism. 
     
     
         4 . The binding facility according to  claim 1 , wherein the wire feeding mechanism includes a guide part configured to regulate a position of each wire along a direction, in which a plurality of wires are aligned in parallel, and provided to the wire pullout mechanism. 
     
     
         5 . The binding facility according to  claim 1 , wherein the wire feeding mechanism includes a guide part configured to regulate a position of each wire along a direction, in which a plurality of wires are aligned in parallel, and provided between the wire pullout mechanism and the reel and/or between the wire pullout mechanism and the wire pullback mechanism. 
     
     
         6 . The binding facility according to  claim 5 , wherein the guide part includes a first guide portion configured to regulate moving of the plurality of wires away from each other along the direction in which the wires are aligned in parallel and a second guide portion configured to regulate moving of the plurality of wires toward each other along the direction in which the wires are aligned in parallel, at least between the wire pullout mechanism and the wire pullback mechanism.
