摘要:
A reinforcement binding machine capable of detecting, by the rotation of a reel, that wire on the reel is consumed and the reel, the reinforcement binding machine wherein an interrupter (45) is installed in the cassette case (40) of a binding machine body (21), a cover (46) is rotatably held on a reel mounting shaft (43), an opening part (47) is formed in the cover (46), a projection (53) is formed on the reel (41) and fitted into the opening part (47), and a colour with a lightness different from that of the cover (46) is applied to the projection (53) to detect the rotation of the reel (41) by the interrupter (45).
摘要:
A front end of a loop of a wire fed out to a nose (6) by a binding wire feeding mechanism (1) is pinched by a clamp plate (28) of a binding wire clamping apparatus (25) and the wire is pulled back by driving to rotate reversely a feeding motor (13) of the binding wire feeding mechanism (1). When the wire is brought into close contact with a reinforcing bar (S) and a load of the feeding motor is increased to thereby increase a drive current by a constant amount, a control apparatus stops the feeding motor. Thereafter, the binding wire clamping apparatus (25) is rotated to twist the binding wire to bind the reinforcing bar. Since the wire is pulled back and a length of the wire is automatically adjusted in accordance with a diameter of the reinforcing bar, a state of finishing to bind the reinforcing bar is made to be uniform and also an amount of consuming the wire is reduced.
