Description

Rebar automatic banding device

The present invention is a reinforcing bar automatic bending device for automatically bending the reinforcing bar to a selected shape, more specifically, the reinforcing bar to be manufactured in the reinforcement of the desired shape by bending the reinforcing bar in one of the shapes set in advance in the control panel (control unit) It relates to an automatic banding device.

Currently, reinforcing bars made of a certain shape by bending a straight bar at a predetermined angle are used in a large amount of construction sites.

The device for bending reinforcing bars is classified into manual M / C, semi-automatic M / C and automatic M / C. Currently, semi-automatic M / C or automatic M / C is used for convenience of work.

The automatic M / C consists of a fixing part for fixing the center of the reinforcing bar and a bending head part for bending the bar at an angle, but the semi-automatic M / C does not have a fixing part (center jig) for fixing the center of the bar. It has only a plurality of bending heads.

The automatic M / C can automatically obtain the bent reinforcement of the desired shape only by the operation of the control panel, while the semi-automatic M / C can bend the reinforcing bar after fixing the bending head part manually to the desired position. do.

The semi-automatic M / C is fixed manually after moving it while checking the gap between two or five bending heads with a tape measure. At this time, the thickness of the rebar and the diameter of the roller should be reflected when fixing it. Therefore, it requires considerable repetitive learning and experience, and much time and effort is required for 'roller replacement' and 'base height adjustment' according to the shape and size of the rebar. There was a disadvantage that it was necessary.

Although the automatic M / C is not widely distributed in Korea, it is developed by Tokyo Construction Industry Co., Ltd. (TOYO) of Japan and is gradually being distributed in Korea.

Automated M / C of Tokyo Construction Industry Co., Ltd. was registered as Japanese Patent No. 2686415 in Japan.

Referring to the above patent (the basic structure is similar to FIG. 1 of the present invention, it will be easily understood with reference to FIG. 1). The fixing part for fixing the reinforcing bar is formed, and both sides of the fixing part is provided with a bending head part for bending the reinforcing bar at a predetermined angle. Both ends of the mount are provided with motors for moving the bending head portion along the mount, and the bending head portion moves along the mount by a chain connected to the motor according to the driving of the motor. The control panel is a control unit that controls the device as a whole, and is electrically connected to each part of the device to control the movement distance of the bending head portion, the bending angle, the operation of the fixed portion (center jig), the operation of the motor, the operation of various cylinders, and the like. To control.

Looking at the operation, the operator first selects the desired shape from the control panel and enters a value. At this time, it should be noted that the automatic M / C of Tokyo Construction Industry Co., Ltd. is fixed to input only the outer dimension of the shape to be banded. In the case where the shape to be banded is recorded in the drawing received from the ordering company, the center dimension is recorded, the operator must correct the outer dimension in consideration of the thickness of the reinforcing bar, and then input the corrected outer dimension.

After selecting the shape in this way and entering the dimensions, pressing the start button, the two bending head parts are gathered about the fixed part (center jig), and are positioned at the selected position while holding the zero point again.

Then, put the reinforcing bar to be banded, press the foot switch to fix the center of the reinforcing bar and then proceed with the bending work. After the bending of the rebar, the banded rebar can be removed and the new rebar can be placed again to continue to produce the same product. At this time, as long as the shape of the reinforcing bars does not change, the position of the bending head portion once set is fixed to the position without changing and continuously performs the bending operation.

However, the bending device of the Tokyo Construction Industry Co., Ltd. has the following fatal disadvantages.

First, as described above, since the control panel is fixed to input only the outer dimension of the reinforcing bar to be banded, when the operator orders the center dimension by recording the order, the operator corrects the outer dimension in consideration of the thickness of the rebar. Not only is it cumbersome to enter a dimension, but there is a problem that a defective product is generated if a mistake is made by mistake.

Secondly, when bending the reinforcing bar in the bending head part, when the thickness of the reinforcing bar is thick, the bending head part moves without being firmly fixed, and there is a problem that a defective product is generated because the bending is not performed at a desired position. This is because the fixing part is simply fixed to the mounting table in the form of a pad, a pulling phenomenon occurs when reinforcing bar bending, which results in a poor processing.

A roller is formed in the banding head part, and the roller head rotates on the mounting table, so that the banding head portion moves on the mounting table. The bending head part is moved inward when bending the thick rebar because the force holding the banding head part is weak. Moving pull occurs.

Therefore, the conventional apparatus can process only two of the minimum thicknesses D10 and D13 of rebar. In the case of D16, however, machining is possible, but at the same time, only two pieces can be processed at the same time, which is low in productivity and is rarely used in the case of D16. The number of machining by standard is up to 6 in the case of D10, up to 5 in the case of D13, and up to 2 in the case of D16.However, the bending head part is not firmly fixed and pulling occurs. I'm using it.

Third, in the fixing part for fixing the rebar, the height of the reinforcing bar to be placed according to the standard (thickness) of the reinforcing bar to be adjusted, at this time there was a problem that the new height of the cradle must be replaced every time.

In addition, when bending a plurality of rebars at the same time, there was also a problem that the workers have to align each other because the bars are not aligned neatly.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to simply and simply input various dimensions (center dimension, outer dimension) to a desired shape on a control panel without correcting the size to obtain reinforcing bars of a desired shape. It is to provide a reinforcing bar automatic bending device.

Another object of the present invention is to provide a reinforcing bar automatic bending device that can obtain a reinforcing bar of the desired value and shape even if the diameter of the reinforcing bar (diameter 25mm) without a numerical error.

Referring to Figure 1, the rebar automatic bending device of the present invention is laid down sideways with an H-beam elongated mounting 100 having an English letter 'I' shape, the fixing portion 300 is installed in the center of the mounting to fix the rebar A bending head part 200 installed at both sides around the fixing part to bend the reinforcing bar at a predetermined angle, a driving motor 400 moving the bending head part along the mounting table, and a control panel to control the operation of the device as a whole; 500 is made. In addition, a manually controlled manual switch 600 is installed to temporarily emergency stop or drive the automatic banding device. The manual switch is electrically connected to a scaffolding switch (not shown), and the operator may start the bending work by sending a 'bending work start' signal by pressing the scaffolding switch.

The two bending heads 200 are installed around the fixing part 300, and the driving motor 400 is also installed at both ends of the mounting table 100. Each of the driving motors 400 is each of the bending heads. The part 200 is moved. The bending head part 200 and the driving motor 400 are connected by a chain (not shown), and the bending head part 200 is driven by the driving motor 400 in response to a signal from the control panel (control panel). It is movable along 100.

Control panel 500 is a control unit for controlling the rebar automatic bending device of the present invention as a whole, when the operator selects one of the shape of the reinforcing bar preset in the control panel 500 and enters a numerical value and then press the (Move) start button In response to the control signal of the control box 500, the bending head part 200 moves toward the fixing part to be in close contact. The bending head part 200 in close contact with the fixed part may be opened again by a selected position after the zero point is taken. Thereafter, the bending head portion 200 is fixed to the fixing lever 102 installed under the upper plate portion of the mounting table by driving the cylinder 110.

That is, the control panel 500 is a control unit for controlling the rebar automatic bending device of the present invention as a whole, is electrically connected to each part of the device, the movement of the bending head portion, the operation (banding, alignment) of the bending head portion, fixed portion Controls operation, drive motor drive and cylinder operation.

It is noted that in the present invention, the shape of the reinforcing bars to be bent to the control panel 500 (that is, the control unit) is set in advance, and the outside dimension or the center dimension of the reinforcing bars to be formed can also be input.

After the operator selects the desired shape of the rebar, the operator can simply operate the control panel of the present invention by inputting the length (outer dimension or center dimension) of the side of the selected shape. Selection of the desired shape of the reinforcing bar can be selected by a touch screen method.

The operation of the apparatus of the present invention will be described below.

First, the operator selects the shape of the desired rebar in the control panel 500 with a touch screen, inputs the length of the side of the selected shape, and then presses the (Move) start switch. The movement start switch is a switch instructing the movement of the bending head unit 200.

Then, the bending head parts 200 on both sides move in the direction of the fixing part 300 by the driving of the driving motor 400 according to the electrical signal of the control unit (control panel) to be in close contact with both sides of the fixing part 300. At this time, the distance is recognized as O point and is set. Then, the bending heads 200 on both sides are opened again and moved to the selected position to stop.

After the bending head portion 200 stops, the reinforcing bar to be processed is placed on the horizontal surface 324 of the mounting portion 322 and the mounting portion 202 and the rotating portion 206 of the bending head portion 200.

In the present invention, in order to align one end of the reinforcing bar in the required position, the membrane 550 is provided on the bending head portion 200 on one side. The membrane 550 is adjusted and fixed to a required length, and serves to stop one end of the rebar and at the same time, it is installed to align one end of the rebar.

After placing the rebar, press the foot switch, the start button. The foot switch is a switch that commands the start of the bending work. Manual switch may be used, but the foot switch is provided for the convenience of the operator.

When stepping on the foot switch, the bending operation starts. First, the alignment bar is driven and the reinforcing bar is fixed by the central fixing part.

When bending several bars at once, it is necessary to arrange / arrange the bars on the horizontal surface 324 of the mounting part 322 evenly. In the present invention, the alignment bar 210 is formed at one side of the bending head part 200. ) And an alignment bar drive cylinder 212. By the driving of the alignment bar driving cylinder 212, the alignment bar 210 once up and down again. That is, by shaking the bars once, the bars are aligned neatly.

The fixing of the reinforcing bars by the fixing unit is performed by the operation of the shank moving cylinder 306 and the horizontal moving cylinder 308. Fixing of the reinforcing bar will be described below with reference to FIGS. 3A to 3B.

With the center of the rebar fixed, the rebar bending takes place. Initially, the rebar is placed on the cradle 202 and the rotating portion 206 of the bending head portion 200, in which state, the central fixed shaft 204 is advanced forward and in close contact with the support plate 208. Then, the reinforcing bar is located on the cradle 202 and the upper portion of the rotating part 206, and is in a state located below the central fixed shaft 204. In this state, the rotating unit 206 is rotated by the selected angle, thereby bending the rebar.

Here, it should be noted that, as described above, in the conventional Japanese patent of Tokyo Construction Industry Co., Ltd., when the thickness of the reinforcing bar is thick, the bending head part 200 moves in the direction of the fixing part 300 when bending the reinforcing bar. That is, there was a problem that a pulling phenomenon occurs, resulting in a poor machining result.

However, in the reinforcing bar bending device of the present invention, the fixing rack 102 is installed on the upper plate of the mounting table 100 along the longitudinal direction of the mounting table, and the fixing head 102 is provided at the bending head portion 200 when bending the rebar. Clamp 106 is installed to be firmly fixed to the bending head portion 200 to prevent movement. The fixing of the bending head part 200 will be described in more detail with reference to FIG. 2 below.

When the bending of the reinforcing bars, the rotating portion 206 and the center fixing shaft 204 of the bending head portion 200 is moved back to the original position, the fixing portion 300 is to release the fixing of the rebar. Then, the worker recovers the processed rebar.

In the case of repeatedly producing the same shape of rebar, the same operation can be repeated by raising the rebar again and stepping on the foot switch. In this case, as long as the shape or the size of the reinforcing bar does not change, the repetitive operation may be performed without the operation of a separate control box or the movement of the bending head part.

2 is a side schematic view of the bending head portion 200 of the rebar automatic bending device according to the preferred embodiment of the present invention.

Referring to FIG. 2, it can be seen that two fixing legs 102 are installed at the lower side of the upper plate portion 101 of the mounting table 100, one left and one right side.

Teeth 104 are formed in the downward direction of the fixed leg 102, and teeth 104 are formed in the lateral direction of the other fixed rack 102. As shown in FIG. This is to restrain the horizontal movement and the vertical movement of the bending head portion 200.

Clamps 106 are respectively provided in the front direction of the teeth 104 of the fixing legs 102, and the clamps 106 are formed with moving legs (not shown) that engage with the fixing legs. The meaning of the movement in the 'movement rack' does not mean that the 'movement rack' itself moves, but because it is installed in the bending head part, it means that the movement lever also moves along the fixed lever as the bending head part moves. When the teeth of the movable leg and the teeth of the fixed rack are engaged with each other, the banding head part is fixed. When the teeth are engaged with each other, the banding head part is firmly fixed. When the teeth are released, the banding head part is also released.

Each clamp 106 is clamped to or released from a fixed rack 102 in accordance with the drive of each cylinder 110 (one cylinder is shown but the other is not shown).

When the bending of the reinforcing bar is fixed and the moving lever is firmly engaged, the bending head portion is firmly fixed, and when the bending of the reinforcing bar and the bending head portion is moved by the drive of the cylinder 110 is separated from the fixed rack 102. .

In this way, the clamp 106 is clamped to the fixed rack 102, that is, in a state in which the moving rack is firmly engaged with the fixed rack, the bending of the reinforcing bar is made, thereby allowing the movement or movement of the bending head portion 200 to be inherently performed. It will be able to block.

Preferably, the pitch of the teeth of the fixed and moving teeth is preferably 3 mm, since the thickness of the rebar is standardized at 3 mm intervals.

After the bending of the reinforcing bar is finished, the clamp 106 is released from the fixing lever 102, so that the clamping bending head portion 200 is movable along the mounting table 100 from side to side.

In addition, in the present invention, an electric brake device (not shown) is installed inside the drive motor 400 installed at both ends of the mounting table so as to move the bending head part, so that the bending head part 200 moves during reinforcing bending. It can be prevented. The driving motor 400 to which the electromagnetic brake device is attached may be used that is typically used in an industrial site.

3 to 5, the fixing stand 302 is fixed on the mounting table 100, and the shankdong cylinder 306 is installed on one side of the mounting table 302, and a vertical fixing part 320 is installed on the other side. The platform 304 is installed on the shank moving cylinder 306, and the cylinder 308 for horizontal movement is installed on the platform 304. The horizontal movement cylinder 308 is connected to the fixing bar 310 having a ring shape to fix the rebar. The shank movement cylinder 306 serves to move up and down the settable 304, and the horizontal movement cylinder 308 serves to advance the fixed bar 310 forward and backward.

Referring to the operation, in the state of FIG. 3, that is, the rebar (not shown) is placed on the horizontal surface 324 of the mounting portion 322, the horizontally movable cylinder 308 advances the fixed bar 310. It becomes the state of 4. In this state, if the shank-type cylinder 306 is operated to lower the mounting platform 304, the fixing bar 310 is naturally lowered accordingly. When the fixed bar 310 is reversed by the operation of the horizontally movable cylinder 308 again in that state, the fixed bar 310 firmly fixes the rebar 700 as shown in FIG. 5.

6 is a perspective view of a portion of the fixing portion of the reinforcing bar automatic rebar bending device according to an embodiment of the present invention, the mounting.

Referring to FIG. 6, a vertical wall surface 312 fixed to the resttable 304 is formed, and a vertical fixing part 320 fixed to the fixing stand 302 is formed. An uneven portion 312a is formed on the inner side surface of the vertical wall 312 so that the rebar does not move easily. In the case of reinforcing bar, a protrusion having a unique shape is formed on the surface thereof, and the protrusion is caught by the uneven portion 312a so that it does not move easily.

Mounting portion 322 is coupled to the vertical fixing portion 320. The mounting portion 322 is formed in a substantially '-' shape, the horizontal surface 324 is formed on the top, is fixed tightly to the vertical fixing portion 320 by the bolt 330. The surface of the horizontal surface 324 is formed with an uneven portion so that the rebar does not move.

In addition, the uneven portion 320a is formed on the surface of the vertical fixing portion 320 in contact with the mounting portion 322, and the uneven portion 322a is formed on the surface in contact with the vertical fixing portion 320. It is.

In the device of the present invention, if you want to adjust the height of the mounting portion 322, first loosen the bolt 330, and then adjust the height of the mounting portion 322 appropriately, and then the vertical fixing portion 320 and mounting When the bolt 330 is inserted into the bolt insertion hole 322b and the insertion hole 320b again while being fixed to the part 322, it is possible to fix and adjust the height of the desired mounting part 322. Accordingly, the height of the mounting portion 322 can be freely adjusted according to the standard (thickness) of the rebar (rebar) placed on the mounting portion 322 without replacing the mounting portion and the vertical fixing portion.

Preferably, the uneven portion has a constant pitch. Since the thickness of the reinforcing bars is standardized at intervals of 3 mm such as 10 mm, 13 mm, 16 mm, 19 mm, 22 mm, 25 mm, and the like, the

pitches

320a and 322a are preferably 3 mm.
