Title: Strapping wire feed mechanism for reinforcing bar strapping machine
Inventor: ISHIKAWA NOBORU
IPC: B65B13/18
Filed: 2001-08-08
Abstract: PROBLEM TO BE SOLVED: To improve stability in feeding a strapping wire of a reinforcing bar strapping machine. SOLUTION: Two driving gears 8 and 9 with a V-groove are disposed on a strapping wire feed path, with which follower gears 10 and 11 with a V-groove are engaged, respectively. The two follower gears 10 and 11 are mounted on a single gear holder 15, which is mounted on a base plate so that it can swing and move fore and aft. A lever 18 equipped with a spring 20 is used to push the gear holder 15 to bring the two follower gears 10 and 11 into elastic contact with the driving gears 8 and 9. Even if the follower gear 10 on an upstream comes away from the driving gear 8 due to a bend of the strapping wire, since the follower gear 11 on a downstream engages with the driving gear 9, feeding is not suspended nor gets unstable. Thus, a feeding amount of the strapping wire can be controlled to be constant.
