Binding machine

Abstract

A binding machine includes: a holding portion configured to hold a tip end side of a cured wire rod; a feed unit configured to hold a base end side of the wire rod, the tip end side of which is held by the holding portion, such that the base end side of the wire rod is able to be fed out; a twisting unit configured to twist the wire rod; and a control unit configured to control the feed unit and the twisting unit. The control unit is configured to control the feed unit to feed the wire rod when detecting a first signal, and is configured to control the twisting unit to twist the wire rod when detecting a second signal.

What is claimed is: 
     
         1 . A binding machine comprising:
 a feed unit configured to hold a base end side of a wire rod, a tip end side of which is open, such that the base end side of the wire rod is able to be fed out;   a holding portion configured to hold the tip end side of the wire rod that is fed out by the feed unit;   a twisting unit configured to twist the wire rod, the tip end side of which is held by the holding portion; and   a control unit configured to control the feed unit and the twisting unit, wherein the control unit is configured to control the feed unit to feed the wire rod when detecting a third signal, is configured to control the holding portion to hold the tip end side of the wire rod when detecting a fourth signal, and is configured to control the twisting unit to twist the wire rod when detecting a fifth signal.   
     
     
         2 . The binding machine according to  claim 1  further comprising:
 a third operation unit configured to output the third signal when a third operation is performed by an operator. 
 
     
     
         3 . The binding machine according to  claim 2 , wherein
 the third operation unit is configured to output the fourth signal when a fourth operation is performed by the operator.   
     
     
         4 . The binding machine according to  claim 3 , wherein
 the third operation unit is configured to output the fifth signal when a fifth operation is performed by the operator.   
     
     
         5 . The binding machine according to  claim 1  further comprising:
 a fourth operation unit configured to output the fourth signal when a fourth operation is performed by an operator. 
 
     
     
         6 . The binding machine according to  claim 1  further comprising:
 a fifth operation unit configured to output the fifth signal when a fifth operation is performed by an operator. 
 
     
     
         7 . The binding machine according to  claim 1 , wherein
 the feed unit is configured to pull back the base end side of the wire rod, the tip end side of which is held, and   when detecting the fifth signal, the control unit is configured to control the feed unit to pull back the wire rod, and then is configured to control the twisting unit to twist the wire rod.   
     
     
         8 . The binding machine according to  claim 4 , wherein
 the third operation unit is a trigger switch, and   at least one of the third operation, the fourth operation and the fifth operation is a one-press operation, and at least one of the remaining operations is a multiple-time-press operation.   
     
     
         9 . The binding machine according to  claim 1  further comprising:
 a detection unit configured to output the fifth signal when a binding object is located inside the wire rod, the tip end side of which is held. 
 
     
     
         10 . The binding machine according to  claim 1 , wherein
 in a case where the control unit detects the third signal so as to feed the wire rod, when a feed amount of the wire rod reaches a predetermined amount, the control unit is configured to stop the feed of the wire rod.
