Automatic rebar binding device {AUTOMATIC BINDING APPARATUS FOR REINFORCING ROD}

The present invention relates to a reinforcing bar automatic binding device, specifically, the length of the binding line can be adjusted according to the thickness of the reinforcing bars and the number of reinforcing bars to be easy to use, shorten the working time and significantly reduce construction costs It relates to a rebar automatic binding device that can be.

In the field of construction and civil works, reinforcing bars are installed in concrete structures to reinforce the strength of buildings and works. That is, a plurality of reinforcing bars in a mold for concrete are connected to each other side by side or at a right angle and then installed in the outside.

In this work, it is necessary to bind the bars connected to each other, and various methods for binding the bars have been proposed. Among them, two bars are joined to each other and welded, and two bars are arranged so that the ends of the bars overlap each other, and then a method of binding with the wires is typical.

In the method of binding the two reinforcing bar ends using the wire of the above-described method takes a lot of work time and work efficiency is reduced because all the work is done by hand. In particular, since the quality state (binding force, etc. of the reinforcing bar) is sharply prepared according to the skill of the operator, a skilled person with a high skill level is required as compared to other processes, and accordingly, a high cost is required.

In order to solve this problem, "Automatic rebar binding machine (Domestic Patent Publication No. 10-436446)" has been filed by the present applicant. Looking at the conventional reinforcing bar automatic binder with reference to the 10-436446, the case is provided with a binding line guide at one end, and a binding line supply device wound around the cylindrical reel formed on the rear of the case, A binding line feeding device for moving the binding line supplied from the binding line receiving device to move the front of the binding line by the operation of the operation lever to move the binding line forward, and to operate the first switch; The swivel ties are mounted on the swivel gear, and the drive motor is rotated by the operation of the first switch to revolve the swivel gear around the reinforcing bars to reinforce the reinforcing bars; Binding line cutting device for cutting the ties line wound on the reinforcing bar by operating the second switch reverse rotation of the drive motor, ties cut by the ties line cutting device To give a twisting both ends by receiving the rotational force generated from the driving motor and a coupling line twister device is formed in one end twister twister shaft to twist the binding line.

The conventional automatic reinforcing bars as described above can reduce the working time, improve the work efficiency and reduce the construction cost to some extent, but if the thickness of the reinforcing bars and the number of reinforcing bars are different from the pre-calculated value or number There is a disadvantage that the binding force is lowered.

That is, the length of the binding line which is discharged through the conventional automatic reinforcing bar automatic winding along the circumference of the reinforcing bar is always constant. Therefore, when the thickness and number of the reinforcing bar is more than the pre-calculated value and number, the length of the twisted portion for fixing the binding line is shortened and the binding force is lowered. On the other hand, if the thickness and number of the reinforcing bar is less than the pre-calculated value and number, the length of the twisted portion for fixing the binding line is prolonged to protrude to the outside there is a risk of injury to the workers. In particular, when the twisted portion is long, stress is concentrated at one portion of the twisted portion in the process of twisting the binding line, and thus the binding force may be lowered.

Therefore, the present invention is to solve the above-mentioned problems, it is possible to adjust the diameter of the binding line according to the thickness of the reinforcing bars and the number of reinforcing bars to be easy to use, shorten the working time and significantly reduce the construction cost The purpose is to provide a reinforcing bar automatic binding device that can be.
