Reinforcement binding machine and reel used for the machine
A reinforcement binding machine and a reel used for the machine capable of solving such a problem that wire comes out of the flange of the reel whereby wire feeding is disabled, wherein a recessed part ( 42 A) is steppingly provided at the opening edge part of a cassette case ( 40 ), the flange of the cassette case ( 40 ) on the opening part side is formed in a large flange ( 55 ) having a diameter fitted to the recessed part ( 42 A) of the reel ( 40 ), an engaging claw ( 47 ) for preventing the reel from coming out of a reel mounting shaft ( 43 ) is formed on the inner peripheral surface of a hub hole ( 51 ) for inserting the reel mounting shaft ( 43 ) of the reel ( 40 ) therein, and the engaging claw ( 47 ) and the reel mounting shaft ( 43 ) are engaged with each other so that the reel ( 41 ) can be rotated intermittently.
1. A reinforcement binding machine in which a reel mounting shaft is formed in a case to be mounted to a binding machine main body, a reel around which a reinforcement binding wire is wound is attached to the reel mounting shaft, and the wire is twisted after being wound around reinforcing bars to bind the reinforcing bars, wherein there is formed at an edge of an opening of the case into which the reel is inserted an annular recess having a diameter larger than a diameter of a bottom portion of the case, and wherein the case opening side flange of the reel is formed as a large flange having a diameter allowing insertion into the recess.
2. A reel used for a reinforcement binding machine in which a reel mounting shaft is formed in a case to be mounted to a binding machine main body, the reel around which a reinforcement binding wire is wound is attached to the reel mounting shaft, and the wire is twisted after being wound around reinforcing bars to bind the reinforcing bars, wherein the case opening side flange of the reel is formed as a large flange having a diameter allowing insertion into the recess formed in the step portion of the opening edge.
3. A reinforcement binding machine in which a reel mounting shaft is formed in a case to be mounted to a binding machine main body, a reel around which a reinforcement binding wire is wound is attached to the reel mounting shaft, and the wire is twisted after being wound around reinforcing bars to bind the reinforcing bars, wherein there is formed at an edge of an opening of the case into which the reel is inserted an annular recess having a diameter larger than a diameter of a bottom portion of the case, wherein the case opening side flange of the reel is formed as a large flange having a diameter allowing insertion into the recess, and wherein there is formed in the inner peripheral surface of a hub hole into which the reel mounting shaft of the reel is inserted an engagement claw for preventing detachment from the reel mounting shaft, there being formed in the outer peripheral surface of the reel mounting shaft a fitting recess allowing entry of the engagement claw.
