Description

An auto-binding apparatus for reinforcing bar}

The present invention relates to an automatic reinforcing bar binder that can automatically bind reinforcing bars in a construction site, and more particularly, to an automatic reinforcing bar binder that can be easily bound in a simple structure using plasticity of a binding line.

Generally, 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 at right angles or at right angles, and a mold is formed by sifting mortar outside.

Among the work performed in this process, the reinforcing bars connected to each other must be bound and fixed, and this work is performed by manual labor of workers.

That is, the binding line is cut to fit the binding portion, and the cut binding line is wound around the desired portion and twisted to bind.

As described above, in the case of the conventional reinforcing bar binding, since the work is performed by hand, the work efficiency is greatly reduced, and thus, a lot of work time is required. This is a big problem in the construction site where construction air needs to be reduced, but at present there is no alternative.

The present invention has been made in order to solve the problems occurring in the conventional reinforcing bar binding work as described above, and the object of the present invention is to provide a device that can automatically bind the reinforcing bar, not manually.

Another object of the present invention is to provide an automatic reinforcing bar binder that can be miniaturized due to its simple structure and can be suitably applied to various working situations.

The above object can be achieved by the configuration of the present invention using the firing of the binding line, will be described in detail with reference to the accompanying drawings.

The present invention is characterized by having a binding line curved guide means formed with a turning guide for turning the binding line in a circle around the binding material by using the firing of the binding line.

In general, the bundling wire used for binding the reinforcing bar uses a strong plastic wire. This is because the bound state can be maintained for a long time without deforming only when the firing is strong.

The present invention is configured to perform the binding operation by using the above-described plasticity of the binding line.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall configuration diagram showing the overall configuration of the present invention, one side of the case is in an open state, and the binding line curved guide means is shown in a cross-sectional state, and FIG. 3 is a side cross-sectional view taken along line AA of FIG. 2, and FIG. 4 is a partially cut-away perspective view of the binding line curved guide means of the present invention.

As seen from the drawings, the present invention is provided in the case 1 and the binding line feeding means installed in the case and the cutting means installed in the case and cutting the binding line 2 to a predetermined length and the case. Binding line curved guide formed of a turning guide (12) formed by including a binding jig 20 for twisting the binding line to make the binding line turn around in the circle using the plasticity of the binding line. A means is provided.

The binding line 2 having plasticity is wound on the binding line accommodating means 5 such as a winding drum and stored therein, and then guided to the curved guide means by the binding line feeding means.

Since the binding line 2 has plasticity, when the guide line is first drawn out and drawn out in a predetermined way, the binding line 2 is transported according to the shape of the road and the shape of the binding line to be transported has the shape of the guide road.

In other words, if the binding line is to pass through the circular turning guide 12, the passed binding line also takes the same circular shape as the turning guide, using this to accurately surround the reinforcing bar around the binding material This creates a state that you can.

The binding line curved guide means is formed of a body 10 in which an entry port 3 into which a binding object can enter is formed on one side, and the binding line 2 passes through the inside of the body 10. It is preferable that the guide path 12 is formed to penetrate in a circular shape as partially open as the portion corresponding to the entry port (3).

Even when the entrance port portion of the turning guide path 12 is open, the binding line conveyed therein enters the turning guide path 12 that passes again through the entrance part by firing and continues round the turning guide path. I can do it.

The opposite side of the entrance port 3 of the turning guide path 12 is formed as an open portion 14 in which a predetermined section is opened so that the tip portion of the binding fixture 20 can be located, thereby opening the opening portion 14. It is preferable to allow the binding line passing through to be twisted by the rotation of the binding jig.

Therefore, since the opening portion 14 only needs to secure enough space for the tip of the binding jig to be located, only a very small space needs to be opened.

As shown in FIG. 5, the binding jig 20 is connected to the rotating jig rotating shaft 21 and configured to be rotatable, and a plurality of twisting protrusions are formed at the distal end thereof so that the binding line passage 23 is formed therebetween. 22) is preferably formed so that the binding line passing through the passage hole between the plurality of twisted parts can be twisted by the rotating twisted part.

Of course, the binding jig will be capable of various modifications so that the binding is made firm by twisting the binding line.

The binding jig rotating shaft 21 may be configured to be connected to the drive motor 25 to rotate.

In addition, the present invention provides a guideway guide pipe 16 for guiding the bundling line 2 supplied by the bundling line feeding means to enter the turning guide path 12, the one end of which is the turning guide path ( 12) should be connected and installed to communicate with.

At this time, the guide pipe guide tube should be formed so that the portion connected to the turning guide path can be smoothly connected to the shape of the turning guide path, which is for the smooth progress of the binding line.

In order to easily enter the binding line into the guideway guide pipe, it is necessary to appropriately configure the binding line feeding means, which draws the binding line of the binding line receiving means 5 to the guideway guide pipe smoothly. It must be of a transportable configuration.

Feeding means is not limited to the specific structure because a variety of methods are already used in various industrial fields, for example, the roller 30 is rotated by receiving a rotational force by the drive motor 35 as shown in Figures 1 and 7 And one side thereof is connected to the roller 30, and the other side thereof is connected to the feeding belt 31 connected indefinitely by an adjacent roller 30`, and a pair of upper and lower sides face each other and rotates to connect the ties to the contact portion. (2) can be configured to be pulled out by the curved guide means.

A switch 8 for operating the drive motors 35 and 25 may be installed at one side of the outer case, and the operation of the switch may take a structure operated by a button 6 which is a conventional method.

In addition, the battery 7 may be accommodated and installed in the case to supply power to the driving motor.

As a structure in which the rotational force of the driving motor is transmitted, various axial connection structures can be used, and in this embodiment, a feeding shaft (34) connected to the driving motor is a roller (bevel gears 33 and 32). 30), a structure capable of transmitting rotational force was taken.

Of course, in addition to this, various rotational force transmission structures may be used, and a flexible (flexible) rotating shaft may be used in a specially shaped case so that it may be used in a complicated shape structure.

Of course, the hollow guide tube 17 may be installed in a certain section in order to accurately guide the binding line from the binding line receiving means 5 to the feeding means.

In addition, the cutting means of the bundling line may be used a variety of cutting means. In the present invention, as shown in Figures 2 and 8 was configured using a disk-shaped cutting knife 40.

The cutting knife 40 is fixed to the cutting means operating piece 26 on one side of the binding jig rotating shaft 21, so that when the cutting means operating piece 26 is rotated by a certain amount to be rotated while being pushed by the operating piece. Installed by protruding the cutting knife rotary rod 41 on one side of the disc-shaped cutting knife 40, the cutting means operating piece 26 rotates as the binding fixture rotary shaft 21 rotates, the cutting means operating piece It is preferable that the disc-shaped cutting knife 40 is configured to rotate while the cutting knife rotating rod 41 is pushed in accordance with the rotation of the 26.

When the cutting knife is rotated by setting the position of the disc-shaped cutting knife so that the binding line 2 passes inside the rotation radius of the blade portion of the cutting knife 40, it is preferable that the binding line is configured to be cut. .

Referring to the operation principle of the subject innovation through the above configuration with reference to the drawings as follows.

First, the binding line curved guide means of the present invention enters the binding material so that the binding material 9 such as reinforcing bars enters the entrance port 3 of the binding line curved guide means of the present invention.

Subsequently, when the button 6 of the present invention is pressed, the driving motor 35 is operated to rotate the feeding shaft 34, and this rotational force operates the bundling line feeding means through the bevel gear. The binding line 2 is inserted into contact surfaces of the upper and lower feeding belts 31 of the binding line feeding means, and then moves toward the binding line curved guide means as the feeding belt rotates.

The conveyed binding line 2 enters the guideway guide pipe 16 and the

It is introduced into the turning guide path 12, and the feeding means continues to move along the turning guide path as it pushes the binding line.

At this time, the binding line entering the turning guide path 12 continues through the turning guide path through the opening 14 (see FIG. 9A).

While passing through the opening portion 14, at the same time passes through the binding line passage opening 23 of the binding fixture 20 located in the opening portion (see Fig. 5).

The binding line 2 moving along the turning guide path passes through the open entrance port 3 again and enters the turning guide path 12 on the other side and continues to move to draw a circle.

The circumferential binding line 2 passes again through the opening 14 and proceeds again to a predetermined position, and the turning of the binding line is completed (see FIG. 9B).

Subsequently, the driving motor 25 is operated to rotate the binding fixture rotating shaft 21. As the binding fixture rotating shaft 21 rotates, the binding fixture 20 rotates, and the binding fixture rotates to bind the binding fixture. The binding line passing through the line passing port 23 is twisted (see Figs. 9C, 9D and 5).

The cutting line is twisted while the cutting line is operated to cut the binding line (can be configured to operate the cutting unit before the binding line is twisted, which is an appropriate gear ratio between the binding fixture rotary shaft 21 and the cutting unit). Or it may be implemented using a separate interlocking means, detailed description is omitted because it is a conventional technology), the binding line is twisted in a circle by twisting the binding line continues to reduce the radius of Figure 6a and Figure As shown in 6b, the turning guide path 12 is separated through the binding line separation gap 13 formed in communication with the lateral direction of the turning guide path 12 and is narrowed toward the binding object 9 so as to be twisted. (See Figure 9C, Figure 9D).

When the binding line is completely twisted and the binding unit is firmly bound, the operation of the driving motor 25 is stopped and the binding jig is stopped and the binding operation is completed, thereby deviating from the present invention.

The operation of the drive motors 25 may be continuously operated while the button 6 is kept pressed, or the timer may be set to press the button once so that the drive motors may be operated sequentially. Since it is a known technology, the detailed description thereof will be omitted.

As described above, the present invention provides an effect of greatly improving the work efficiency by enabling the automatic binding of the reinforcing bar by using the physical property of plasticity of the binding line usefully.

In addition, the present invention encapsulates the binding material by using the firing of the binding line, and thus the structure is very simple. Therefore, the manufacturing cost can be reduced and the production can be performed at a low cost. will be.
