Reinforcement binding machine

Abstract

A wire feed amount detection mechanism is configured by magnets mounted at an outer peripheral surface of a V-grooved drive gear of a wire feed mechanism and a magnetic sensor mounted on a body. A reinforcing bar winding turn number-setting switch is provided on the body. A control portion controls a wire feed amount of a wire feed mechanism based on a set value of the reinforcing bar winding turn number-setting switch. The number of turns of the wire around reinforcing bars can be arbitrarily set, for example, to any one of 1 to 4, and the binding can be effected with a binding force corresponding to a strength required by binding portions. As a result, with respect to those binding portions requiring a low binding force, the binding is effected with a smaller turn number, so that the amount of consumption of the wire can be saved, and besides those pipes (such as electric wiring pipes and hot water pipes) which are lower in strength than the reinforcing bars can also be bound together.

Description

technical field [0001] The present invention relates to a steel bar binding machine, and particularly relates to a steel bar binding machine capable of arbitrarily setting the number of winding cycles of a steel wire wound around a steel bar. Background technique [0002] In order to save labor in the steel bar binding process, there is an electric steel bar binding machine that winds the steel wire around the steel bar and binds it. A steel bar binding machine, which includes a steel wire conveying mechanism, a steel wire cutting mechanism and a steel wire torsion mechanism, uses the steel wire conveying mechanism to send out the steel wire along the curved guidenose, and wraps the steel bar with a steel wire ring, and utilizes the steel wire cutting mechanism from the subsequent The steel wire cuts off the steel wire ring, and at the same time uses the steel wire twisting mechanism to twist the steel wire and bind it in a state close to the steel bar. [0003] The steel w...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned steel bar binding machine, the number of rounds of the steel bar of the steel wire is set to be constant, but there are also binding parts that do not generate a large load or stress and therefore do not require a firm binding force. waste steel wire

In addition, sometimes it is necessary to bind with a stronger binding force than the predetermined binding force, but when the torsional torque is further increased under the specified number of cycles, the steel wire will be twisted, so it is necessary to increase the number of cycles

In addition, it is also considered to use the steel bar binding machine for purposes other than steel bar binding, such as resin piping for electrical distribution, piping for hot water heating, etc., but such piping does not require the same level of binding force as steel bars , if the wire is coiled too much like a rebar, the wire will be wasted, and it may also damage the piping due to excessive binding force
