Abstract

PROBLEM TO BE SOLVED: To always bundle reinforcing bars in a stable manner by forming a longitudinal slit-shaped guide part for guiding a wire, which is sent out, in front of a twisting mechanism, which holds and twists a part of a wire to be wound around reinforcing bars so as to be bound thereto and making the width of the guide part expandable. SOLUTION: If a forward end part of a contact plate 10 of a reinforcing bar bundling machine is pressed against an intersection of reinforcing bars 6, a wire 4 delivered by means of a wire feed mechanism 7 is guided by a guide part and wound around the intersection of reinforcing bars 6. And when a predetermined number of winds of wire are provided, the wire 4 is cut off by a cutting mechanism 8 and twisted and tightened by a twisting hook 9a of a twisting mechanism 9. When the hook 9a is turned, the wire is moved in the turning direction of the hook, however, the wire 4 is situated inside the guide part and hence it is prevented from being moved. And since upper and lower guide members 11a, 11b of the guide part are formed so as to be opened when the guide part is pushed by a twisting part 15, the bundling machine can be easily removed after bundling operation.

2. Description of the Related Art As a reinforcing bar binding machine of this type,
There is known one such as disclosed in Japanese Patent Publication No. 92103. This is to guide the wire from the wire reel on which the binding wire is wound so that it will be wound around the rebar in a loop shape, then send it out, separate it from the wire on the wire reel side, and A part of the wire wound around the wire is held by a twisting hook and twisted to bind the reinforcing bars. As shown in FIG. 6, when the twisting hook twists and rotates, the wire 20 swings to the left and right. Therefore, the winding state around the reinforcing bar 21 is likely to deviate from the shortest distance at the intersection.

By the way, since the twisting mechanism stops when the twisting torque of the wire reaches a predetermined value, the deflection of the wire is also corrected, but the rib 22 is formed on the reinforcing bar 21 and the wire is When the wire 20 is engaged with the rib 22, the wire 20 is shaken as shown in the figure and is bound in a state in which it is stretched more than it should be. In this case, when the concrete is poured, the wire and the rib may be disengaged from each other, so that there is a problem that the binding becomes unstable.
