Description

Automatic binding apparatus for reinforcement bars}

The present invention relates to a reinforcing bar automatic binding machine for automatically binding a cross section of reinforcing bars when reinforcing steel for concrete work in construction or civil engineering. When pressing the operation switch attached to the operation handle against the bundle, the binding line is drawn out, the reinforcing bar is wound and cut to a certain length, and the binding work is performed in a short time, and the binding line is twisted. It relates to a reinforcing bar automatic binder designed to be able to.

As is already known, when concrete is reinforced, reinforcing bars are reinforced to reinforce the concrete, and when reinforcing bars, wire-bonded lines are wound around intersections or joints so that the reinforcing bars are kept in constant shape and spacing. .

This binding work is mainly done by hand until now, and look at the process, while carrying a binding line made of a bundle cut to a certain length, while wrapping the binding line by hand around the area to be bundled, and using both hooks and hooks Twisting like a pretzel is working together.

However, this binding work requires the worker to move and squat at each point to be bound, to bind and work, and to pull out and twist the binding line by hand, which is very difficult and time-consuming. It would be a waste of time and labor costs, and since the binding work itself is a complete manual work, there is no significant binding work, so the strength or method of binding becomes very uneven. will be.

Therefore, devices for automatically binding steel bars have been devised in the meantime, but the configuration is inconvenient to use, or there is a problem in the power transmission structure for automatic operation, so power transmission is not good, so that the twist is incomplete, There was a problem that waste occurs. In addition, there is a problem that the cutting and twisting process is not perfect due to the unstable transfer, the slip occurs due to problems in the movement path of the binding line.

In case of binding work using reinforcing bar automatic binder, it is possible to solve the problems of construction quality as mentioned above, but for some working parts, it may be difficult to work with automatic binding machine due to space constraints. The fact was also a factor that hindered the spread of automatic binding machines. In addition, there is a problem in that the economic loss due to the need to separate the cutting line (cutting to cut to a certain length) for manual work.

An object of the present invention is to provide a reinforcing bar automatic binding machine that can easily bind the rebar automatically by a simple switch operation to solve the above problems.

Another object of the present invention is to provide a reinforcing bar automatic binder that guarantees perfect binding power by ensuring perfect power transmission, preventing slippage during the cutting and twisting of the binding line.

Another object of the present invention is to provide a reinforcing bar automatic binding machine that can be easily carried out by manual equipment at the site where the automatic work is difficult to solve all the binding work in the field with a single equipment.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a perspective view showing an important part of the automatic reinforcing bar automatic binder of an embodiment of the present invention. As shown in FIG. 1, the automatic reinforcing bar as an embodiment of the present invention has a shape in which a clamp 210 is provided to wrap around the reinforcing bar to be bound to the end and provide a transfer path of the binding line 101.

As an embodiment of the present invention, the automatic reinforcing bar binding unit for binding the reinforcing bar 1 from the main spool (not shown) in the automatic reinforcing machine driven by the rotation of the motor 10 as shown in FIGS. 2 and 3. A binding line supply unit 100 for supplying a line 101; A guide passage 211 is provided to guide the binding line 101 supplied from the binding line supply unit 100 to surround the reinforcing bar 1 to be bound, and an end is opened by pulling the clamp wire 212. A clamping part 200 including a clamp 210 having an end closed by an elastic force of the clamp spring 214, and a winding roller 220 on which the clamp wire 212 is wound; An induction passage through which the binding line 101 supplied from the binding line supply unit 100 passes is formed in the main body, and the cutting line 101 surrounding the reinforcing bar 1 is cut and rotated to reinforce the reinforcing bar 1. Rotational binding unit 300 comprising a bending fixing pin 350 for bending the end of the binding line cut by the rotational force of the main body at the inlet of the main body and the binding line guide passage to bind the; And the first driving shaft receiving the power of the motor 10, the second driving shaft transmitting the power transmitted from the first driving shaft to the binding line supply unit 100, and the power transmitted from the first driving shaft. It characterized in that it comprises a power distribution unit 400 comprising a third driving shaft to be transmitted to the portion 200 and the rotary binding unit 300.

That is, in the reinforcing bar automatic binder according to the present invention, a clamp 210 positioned inside the clamp guide 213 as shown in FIG. 2 and sliding along the clamp guide 213 is wound as shown in FIG. 3. Pulling using the 220 and the clamp wire 212 wound around the winding roller 220, the end of the clamp 210 is ready to operate in the open state. At this time, when the reinforcing bar is inserted and the operation switch 11 is turned on, the clamp 210 is rotated as shown in FIG. 2 by the rotation of the winding roller 220 and the restoring force of the clamp spring 214. The binding line 101 for closing and simultaneously binding the reinforcing bar 1 is supplied into the clamp 210 by the supply roller 110 of the binding line supply unit 100.

The binding line 101 supplied as described above passes through the rotary binding unit 300 along the binding line guide passage formed in the rotary binding unit 300 as shown in FIG. 2, and then clamps as shown in FIG. 4. (210) passes through the inside of the clamp (210) along the guide passage (211) provided therein and passes again through the binding line guide passage formed in the rotary binding unit (300) as shown in FIG. The binding line 101 is supplied so that it may be.

When the binding line 101 is wound around the reinforcing bar by the binding line supply roller 110 to completely wrap the reinforcing bar, the operation of the supply roller 110 is stopped, and the motor 10 that has previously supplied the power reversely rotates. To start. At this time, the forward rotation and the reverse rotation of the motor 10 is to perform the reverse rotation after the forward rotation for a predetermined time according to the control signal of a separate control controller (not shown) according to the time already calculated.

The power of the motor rotating in reverse is supplied to the rotary binding unit 300, and the rotary binding unit 300 cuts and rotates the binding line 101 surrounding the reinforcing bar 1 to bind the reinforcing bar 1 to each other. do.

As shown in FIG. 5, the main body 310 of the rotary binding unit 300 includes an upper part 320, a central part 330, and a lower part 340, and between the upper part 320 and the central part 330. The bending fixing pin 350 is bent near the inlet 322 of the binding line guide passage 331 to bend the end of the binding line cut by the rotational force of the main body 310.

Since the bending fixing pin 350 is fixed when the main body 310 of the rotary binding unit rotates, the cut line is bent and the end of the binding line is bent while touching the bending fixing pin 350 simultaneously with the rotation. It is possible to prevent the binding line from slipping in the rotational binding portion during the rotation. That is, the rotation is made in a state where the end of the cut line 101 is bent and bent as shown in FIG.

When the binding machine is removed from the working position after the binding work is completed, the bent portion of the binding line is naturally unfolded by the force of detaching the binding device, and the binding portion where the binding work is completed is separated from the binding device.

Operation of the above-described binding line supply unit 100, the clamping unit 200, the rotary binding unit 300 is driven by the power of the motor 10 provided in the reinforcing bar binder, wherein the power of the motor is connected to the The power distribution unit 400 distributes the same and delivers the same.

That is, as shown in FIG. 8, the first driving shaft 410 receiving the driving force of the first motor transmits the driving force (rotational force) of the motor to the second driving shaft 420 and the third driving shaft 430, and the second driving shaft. The rotational force transmitted to 420 is transmitted to the binding line supply unit 100. In addition, the power distribution unit 400 is configured such that the rotational force transmitted to the third drive shaft 430 is transmitted to the clamping unit 200 and the rotational binding unit 300.

In this case, whether to rotate the second driving shaft 420 is determined according to the rotation direction of the first driving shaft 410, and whether or not the power is transmitted to the rotation binding unit 300 through the third driving shaft 430 selectively. In order to determine, according to the rotational direction of the motor, the supply line of the binding line and the cutting and binding process of the binding line are sequentially performed.

To this end, the automatic reinforcing bar is another embodiment of the present invention in the power distribution unit 400, the second drive shaft 420 to the non-reversing clutch for transmitting the rotational force transmitted from the first drive shaft 410 in only one direction. Is equipped with the 2-1 gear 421, the 2-2 gear 422 for transmitting power to the tie wire supply unit 100 is mounted,

The third drive shaft 430 includes the third drive shaft 431 that receives power from the first drive shaft 410, and the clamp wire 212 is wound around the winding roller 220. The third gear 343 is provided with a non-inverting clutch for transmitting the rotational force of the (430) to the rotary binding unit 300,

As shown in FIGS. 8 and 9, the cylindrical rotating body 441 integrally rotating with the winding roller 220 and the third driving shaft 430 are integrally rotated and positioned inside the rotating body 441. Thus, the apparatus further includes a power control means 440 including an elastic tube 442 for transmitting power in accordance with a relative direction of movement with the rotating body 441 and the load.

Hereinafter, assuming that the case in which the binding line is supplied when the motor rotates in the forward direction will be described as follows. (Even if the case in which the binding line is supplied when the motor rotates in the reverse direction, there is a difference only in the rotation direction. Just as it is)

The first driving shaft 410 connected to the motor to distribute the rotational force of the motor is mounted with the first-first gear 411 at the end of the shaft as shown in FIG. 8, and the first-first gear 411. In this case, the second-first gear 421 of the second driving shaft 420 and the third-first gear 431 of the third driving shaft 430 are engaged with each other. In this case, a non-reverse clutch capable of transmitting power to the second driving shaft 420 is provided between the second-first gear 421 and the second driving shaft 420 only when the second-first gear reverses. .

Accordingly, when the first driving shaft 410 rotates in the forward direction, the second-first gear 421 rotates in the reverse direction, and the second driving shaft 420 also rotates in the reverse direction. At this time, while the third gear 431 also rotates in the reverse direction, the third drive shaft 430 also rotates in the reverse direction, but the third gear 433 is the third drive shaft 430 and the third-3 gear. It is not rotated by the action of the non-reverse clutch provided between the 433, the rotational force of the third drive shaft 430 is not transmitted to the rotation binding unit (300).

As a result, in the forward rotation state of the motor, the power transmitted to the first driving shaft 410 is transmitted to the second driving shaft 420 so that the second driving shaft 420 becomes a reverse rotation state, and the third driving shaft 430 also reverse rotation. It is in the state, but the third-gear 433 is in a stationary state, and thus the clamping is driven by the binding line supply unit 100 and the third drive shaft 430 driven by the second drive shaft 420 The unit 200 is in an operating state, and the rotational binding unit 300 to which power is transmitted by the third and third gears 433 is in a stationary state.

When the second drive shaft 420 is rotated in reverse, the second line gear 422, the bevel gear mounted on the second drive shaft 420 is rotated in reverse, the power line is connected to the second gear 2-422 It is delivered to the payment (100). That is, as shown in FIG. 2, the binding line 101 is supplied while the binding line supply roller 110 rotates by the power transmitted through the second-two gear 422.

The clamp 210, which was maintained in the open state by the clamp wire 212, has a property to move again along the clamp guide 213 by the restoring force of the clamp spring 214, but to be closed again, the winding roller 220 Is rotated in conjunction with the third drive shaft 430 by the power control means 440 can be maintained in an open state.

At this time, when the third drive shaft 430 reversely rotates, the reverse rotation of the winding roller 220 by the restoring force of the clamp spring 214 is possible, and the clamp wire 212 wound around the winding roller 220 is drawn out. In addition, the clamp 210 which is maintained by the clamp wire 212 is moved along the clamp guide 213 by the restoring force of the clamp spring 214 to close again.

As mentioned above, when the motor rotates forward, the third and third gears 433, which are kept in a stopped state by the action of the non-reverse clutch provided between the third drive shaft 430 and the third drive shaft 430, are rotated by the reverse rotation of the motor. When the third drive shaft 430 rotates forward, at the same time, it rotates forward, and therefore, the spur gear 332 provided in the main body 310 of the rotation binding unit 300 connected to the third gear 433 is reversed. Rotation is performed to cut and twist the binding line.

In addition, the power control means 440 is provided in the middle portion of the third drive shaft 430 as shown in FIG. As shown in FIG. 9, the power control means 440 has a cylindrical rotating body 441 on the outside thereof, and a third driving shaft 430 passes therein, and the rotating body 441 and the third driving shaft therein. Between the 430, the elastic tube 442 for transmitting power to each other is mounted to the third drive shaft 430 by a separate fixing means 443, the elastic tube 442 is the rotary body 441 A cutout 445 is formed at one side as shown in FIG. 10 in the form of a leaf spring, in which power transmission is determined according to the relative direction of movement and the load.

Referring to Figure 10 describes the transmission of power delivered to the clamping unit 200 as follows.

That is, as shown in FIG. 10, when the third drive shaft 430 rotates forward (clockwise), the elastic tube 442 provided inside the rotor 441 also rotates forward (the cutout 445 is widened). Direction of rotation) and the rotor 441 also rotates forward by the frictional force between the elastic tube 442 and the inner wall of the rotor 441. At this time, when the load acting on the rotating body 441 is greater than or equal to a predetermined value, the slip occurs between the elastic tube 442 and the rotating body 441 so that the third drive shaft 430 rotates, 441 remains in a stopped state.

The rotating body 441 is configured to rotate the winding roller 220 of the clamp wire 212 integrally. When the clamp 210 is sufficiently pulled by the rotation of the winding roller 220, the rotation A load of more than a predetermined value is applied to the whole, and as mentioned above, slippage occurs between the elastic tube body 442 and the inner wall of the rotating body 441 to automatically rotate the rotating body 441 and the winding roller 220. This is to stop.

However, when the third drive shaft 430 reversely rotates (counterclockwise), the elastic tube 442 provided inside the rotating body 441 may also be reversely rotated (the direction in which the cutout 445 is narrowed). The friction force between the tubular body 442 and the inner wall of the rotating body 441 is reduced, so that the rotating force of the third driving shaft is not transmitted to the rotating body 441 even though the third driving shaft 430 is rotated. However, as mentioned above, the reverse rotation of the winding roller 220 and the rotating body 441 by the restoring force of the clamp spring 214 is as described above.

In this way, the power control means 440 transmits power only in a predetermined direction, and at the same time has a function of blocking power transmission when a load greater than a predetermined value is applied even when power is transmitted.

Another embodiment of the power control means 440 used in the reinforcing bar automatic binder of the present invention is inserted between the elastic tube 442 and the rotating body 441 as shown in FIG. A parallax generating groove in which a cylindrical intermediate rotary body 460 having a bottom surface provided with a generating protrusion 461 and an arc is formed on the upper surface of the disc, and an arc capable of engaging with the parallax generating protrusion 461 of the intermediate rotating body 460. 472 is provided, and the disc lower surface is provided with another parallax generating protrusion 471, and further includes a power transmission disk 470 inserted between the intermediate rotor 460 and the rotor 441. The rotor 441 has a bottom surface having a parallax generating groove 446 having a circular arc formed therein, which can be coupled to a parallax generating protrusion 471 of the power transmission disk 470. do.

Therefore, when the rotational force of the third drive shaft 430 is transmitted to the rotating body 441, even when the third drive shaft starts to rotate, the parallax generating protrusions 461 and 471 rotate along the parallax generating grooves 446 and 472. Power transmission is not performed during the period of time, and power transmission is performed only when the time difference generating protrusions 461 and 471 reach the ends of the time difference generating grooves 446 and 472.

As a result, the rotation of the rotary binding unit 300 is started by the rotation of the third drive shaft 430, and after a predetermined time passes, the winding roller 220 connected to the rotor 441 rotates to open the clamp 210. Will be. As a result of the time difference between the rotational binding unit 300 and the opening operation of the clamp 210, the clamp is opened after the binding line 101 is completely disengaged from the clamp, and thus the clamp may occur at the start of the binding operation. It prevents the collision between the guide passage 211 and the binding line 101 of 210, and ensures the smooth separation of the binding line 101.

The configuration of the power transmission elements involved in driving the rotary binding unit 300 is as follows.

At the end of the third drive shaft 430, a third gear 333 for transmitting power to the rotary binding unit 300 is mounted, and a third gear 433 is used to power the rotary binding unit 300 by the third gear 433. Once this is delivered, a cutting and twisting operation is made.

As mentioned above, when the rotation direction of the motor is changed to reverse rotation, the third-gear 433 of the third drive shaft 430, which has been stopped by the non-reversing clutch, rotates forward while being rotated forwardly. 300 is powered.

As described above, cutting and twisting of the binding line 101 are made by the rotational binding unit 300 which receives the power. The automatic reinforcing bar of another embodiment of the present invention has a rotational binding as shown in FIGS. 5 and 7. A plurality of induction passages 331 are provided in the central portion 330 of the main body 310 of the unit 300 passes through the binding line 101 supplied from the binding line supply unit 100 and is supplied to the clamping unit 200. Is formed and rotates, the binding line cutting portion 321 for cutting the binding line 101 passing through the guide passage 331 by the rotational force is formed on the upper portion 320, the position where the binding line is supplied A plurality of positioning grooves 323 are provided to determine a stop position of the guide passage so that the inlet 322 of the guide passage is positioned, and a rotational binding having a binding line guide groove 341 is provided at the outlet of the guide passage below. Positioning by the elastic force of the sub main body 310 and the spring 361 It characterized in that it comprises a positioning tool 360 for determining the position of the groove 323.

This will be described in more detail as follows.

First, as shown in FIG. 8, a spur gear 332 receiving a rotational force of a motor is provided at the central portion 330 of the main body 310 of the rotation binding unit 300, and thus, the third driving shaft 430. The main body 310 of the rotary binding unit 300 is also rotated according to the rotational force of.

Rotational binding unit body 310 is divided into the upper portion 320, the central portion 330, and the lower portion 340, as shown in Figure 5, the upper portion 320, as shown in Figure 7 A plurality of guide passage inlets 322 through which the binding line supplied from the lead is connected to the rotary binding unit main body 310 are provided to help the binding line supplied from the binding line supply unit be inserted into the rotary binding unit main body 310. .

In order to make the guide passage inlet 322 coincide with the binding line supply outlet of the binding line supply unit when the rotating binding unit rotates and stops by a predetermined number for the binding operation, as shown in FIG. Positioning groove 323 is provided. The positioning groove 323 is a hemispherical concave groove formed on the upper surface of the upper part of the rotational coupling part 320 so that the positioning tool 360 which maintains a predetermined pressure by the elastic force of the coil spring 361 is seated.

At this time, the positioning tool 360 is a spherical shape, the positioning groove 323 is a concave groove corresponding to the shape and size of the positioning tool, the guide passage inlet 322 when the guide passage inlet is out of position. It automatically corrects the position of the).

In addition, as shown in FIG. 2, a binding line cutout part 321 is formed on the upper portion of the rotational binding unit body to cut the binding line 101 passing through the guide passage by a rotational force, and thus, the third driving shaft 430. When the rotary binding unit main body 310 is rotated by the rotation of), the binding line 101 is cut.

In this case, when the binding operation of the reinforcing bars using the automatic automatic binding machine, the automatic binding operation is difficult due to problems in the working space in the actual work site. In this case, it is inevitable to manually complete the reinforcing bar binding work as in the prior art, and in order to facilitate such a manual work, it is necessary to cut and provide a separate auxiliary binding line to an appropriate length.

To this end, the automatic reinforcing bar automatic binding device of another embodiment of the present invention is the auxiliary spool wound by the auxiliary binding line used for manual work, the auxiliary ties supply roller for supplying the auxiliary binding line wound on the auxiliary spool, and the auxiliary spool is supplied from It characterized in that it further comprises an auxiliary binding line supply unit including a cutting means for cutting the auxiliary binding line to a certain length.

That is, as shown in Figure 12, the auxiliary binding line 501 used for the manual binding operation is wound on the auxiliary spool 510, the auxiliary binding line supply roller 520 and the cutting means 530 is auxiliary Driven by the power of the bundling line supply motor 540, the auxiliary bundling line is supplied to the worker.

In detail, the auxiliary tie wire supply motor 540 is operated by an operation of an auxiliary tie wire switch (not shown) separately installed, and the power transmission gear mounted to the shaft end of the auxiliary tie wire supply motor 540 ( 541 is connected to the gear 521 and the rotary gear 531 of the cutting means 530 integrally connected to the auxiliary ties line supply roller 520. The auxiliary binding line 501 wound on the auxiliary spool 510 passes through the auxiliary binding line supply roller 520 and passes through a cutting groove 533 positioned on the rotary gear 531 to be discharged to the outside. It is supposed to be.

At this time, the cutting groove 533 is separated from the rotary gear 531 is mounted on a separate frame, even if the rotating gear 531 is rotated, the cutting groove 533 is fixed to a predetermined position.

Therefore, when the auxiliary tie line supply motor 540 is rotated by the operator of the auxiliary tie line switch operation, the auxiliary tie line supply roller 520 rotates to supply the auxiliary tie line 501, and at the same time the rotation. The cutting cutter 532 mounted on the gear 531 rotates together with the rotary gear 531 and passes through the cutting groove 533 to cut the auxiliary binding line.

At this time, by varying the gear ratio of the rotary gear 531 and the power transmission gear 541, the auxiliary binding line is cut to a certain length, and the shear force generated between the cutting cutter 532 and the cutting groove 533 is also increased. Let's go.

The auxiliary tie wire supply unit 500 is provided in a separate carrying box 600 together with the main spool 102 in which the tie line is wound as shown in FIG. 13, while the worker moves the carrying box on the back. You will be working.

Looking at the action of the automatic reinforcing bar automatic binding device of the present invention consisting of such a configuration as follows.

<Preparation operation>

In the preparatory stage before the automatic reinforcing automatic binder is activated, that is, in the preparatory stage in which the binding work in the previous stage is completed, the binding line 101 passes through the binding line supply passage of the binding line supply unit 100 and enters the induction passage inlet of the rotary binding unit. 322) the front end of the clamp 210 is also supplied to the clamp 210, and the clamp wire 212 wound on the winding roller 220 of the clamping unit 200 is pulled by the clamp 210, the front end of the clamp 210 It is open.

<Insert Rebar Insertion and Start>

In the preparatory state, insert the reinforcing bar (1) to be bound between the open clamp (210) of the automatic reinforcing bar and turn on the switch (11) (on) the automatic reinforcing bar begins to operate. At this time, if the switch 11 is turned on once, the motor 10 operates as a cycle of a predetermined number of forward and reverse rotations as described later. When forward and reverse rotation are completed, the binding of the reinforcing bar is completed. . (Detailed explanation is based on the fact that forward rotation is performed first, and it is natural to operate on the same principle even if reverse rotation is performed first.)

Binding line supply operation

The motor 10 of the rebar automatic binding machine of the present invention performs forward rotation for one full time, and when the forward rotation of a predetermined time is made, the reverse rotation is performed again, and the rotation time of the motor 10 is a rotation time in advance. Determined by a controller for control, such as a determined timer.

When the forward rotation of the motor 10 is carried out, as described above, as the second drive shaft 420 rotates, the supply roller 110 of the binding line supply unit 100 rotates so that the binding line 101 is the main body of the rotational binding unit. It is inserted into the guide passage 331 inside the rotary binding unit body 310 through the guide passage inlet 322 of the upper portion 320, and the inserted binding line 101 passes through the guide passage 331 to clamp the portion ( 200).

At this time, the binding wire supply unit 100 operates and at the same time the winding roller 220 of the clamping unit 200 is also rotated to release the clamp wire 212 wound on the winding roller 220 while the clamp 210 is released. The clamp 210 is closed by moving along the clamp guide 213 by the restoring force of the clamp spring 214.

The closing operation of the clamp 210 and the supply operation of the binding line are performed at about the same time, and the clamp 210 is provided with a guide passage 211, so that the supplied binding line 101 is provided with a guide passage inside the clamp 210. After turning the clamp 210 along the 211, it is inserted into the main body 310 of the rotation binding unit 300 again.

The motor stops when the inserted binding line 101 reaches the guide passage inlet 322 provided at the upper portion 310 of the rotary binding unit body 310 (an inlet symmetrical with the first inserted inlet). , Reverse the rotation again. At this time, the time from the start of the forward rotation to the reverse rotation is determined by the time value already set as described above.

<Cutting and binding operation>

When the motor is switched from the forward rotation to the reverse rotation, the rotation of the second drive shaft 420 that has rotated in the meantime stops, and the third and third gears 433 of the third drive shaft 430 that have been stopped by the non-reversal clutch have been stopped. As the rotation is forward rotation binding unit 300 is received power.

Therefore, the main body 310 of the rotational binding unit which receives the power through the third drive shaft starts rotation, and the winding roller 220 of the clamping unit 200 rotates in the opposite direction while the clamp 210 is opened again. .

As the rotation binding unit body 310 rotates, the binding line 101 inserted into the rotation binding unit main body 310 is cut, and the binding line 101 is twisted by the continuous rotation. The end of the line 101 is bent by the bending fixing pin 350 between the upper portion 320 and the center portion 330 of the rotary binding unit body 310 as shown in FIG.

In this way, the end of the binding line 101 receives the appropriate tension between the rotary binding unit body 310 and the reinforcing bars 1 while the rotary binding unit body 310 rotates, and thus, the rotary binding unit body 310 Loosening does not occur, and thus more solid binding is possible.

When the final binding operation is completed, the user pulls the automatic binder from the bound bar with the appropriate force. At this time, the end of the binding line, which was bent by the bending fixing pin, is released and the binding machine is separated from the rebar.

As mentioned above, the preferred embodiments of the present invention have been described, but this is merely an embodiment of the present invention, and may have various embodiments within the scope of the technical idea of the present invention implemented in the utility model registration claims. Of course.

When the reinforcing bar reinforcement process is carried out using the reinforcing bar automatic binder, which is an embodiment of the present invention, the reinforcing bar can be automatically bound easily by a simple one-touch operation of the switch, and the work can be completed in a short time to improve work productivity and economic efficiency. It is effective to let.

When the binding process of the reinforcing bars using the automatic reinforcing bar of the embodiment of the present invention, since the sliding phenomenon is prevented in the power transmission process by the drive shaft of the power transmission unit is ensured perfect power transmission.

In addition, the slippage generated during the cutting and twisting of the binding line is prevented to ensure a perfect binding force.

In addition, there is an effect that the economic benefit is improved as the machining process of the binding line (the process of cutting in advance to a predetermined length) that is necessary when performing the reinforcing bar binding work by the conventional manual work becomes unnecessary.
