[0049] Figure 6 to Figure 10 Another embodiment of a rebar binding machine and reel is shown. The cassette housing 60 constitutes a part of the reinforcing bar binding machine 20 .

[0050] box case

[0051] Figure 6 to Figure 10 How the reel 61 is installed in the cassette case 60 is shown. Cassette housing 60 is made of a high-grade wear-resistant and bend-resistant plastic, such as polypropylene. A reel mounting shaft 65 protrudes from the bottom 64 of the cassette case 60, and the mounting shaft 36 of the support portion 35 is inserted through the reel mounting shaft 65 to be fixed.

[0052] The upper portion of the cassette case 60 is opened so that the reel 61 can be inserted, and a stepped portion 62 is formed at an edge portion of this opening. The outer edge portion of the large flange 63 of the reel 61 is mounted on the inside of the stepped portion 62 , and the opening of the cassette housing 60 is closed by the outer edge portion of the large flange 63 to pr...

Abstract

A reinforcement binding machine ( 20 ) capable of binding reinforcement ( 22 ) by winding wire ( 27 ) in loop shape around the reinforcement ( 22 ), wherein irregular parts ( 43 ) are formed on the peripheral surface of a reel mounting shaft ( 40 ), an engagement claw ( 47 ) is formed on the inner peripheral surface of a hub hole ( 46 ) of the reel ( 38 ), and an engagement part ( 48 ) engaged with the irregular parts ( 43 ) to prevent the reel ( 38 ) from racing is formed at the tip part of the engagement claw ( 47 ), whereby the reel can be prevented from racing while allowing the reel to rotate in normal and reverse directions so as to eliminate the occurrence of entanglement of the wire.

Description

technical field [0001] The present invention relates to a steel bar binding machine, such as a steel bar binding machine for fixedly binding steel bars intersecting with metal wires, and more particularly to a steel bar binding machine in which when the wire is fed more than the required amount to prevent it from tangling together and involves a reel for use on the machine. Background technique [0002] Regarding the mechanism for preventing the wire from being entangled around the reel of the steel bar binding machine, Japanese Patent JP11-104777A filed by the applicant discloses "braking mechanism for the wire reel of the steel bar binding machine". [0003] In this steel bar binding machine, wherein, the rotation of the wire reel is braked almost simultaneously with the completion of feeding of the wire, thereby preventing the wire from being tangled due to the idling of the reel. [0004] Figure 12 Such a reinforcing bar binding machine is shown, the reel 2 around whic...
