Description

[0001] APPARATUS OF AUTOMATICALLY TREATING STEEL REINFORCING BAR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic machining apparatus for a steel reinforcing bar, and more particularly, to a steel reinforcing bar automatic machining apparatus capable of automatically transferring, bending and cutting a steel reinforcing bar or a rebar.

Rebar is a reinforcing bar used in reinforced concrete. It can be divided into a circular reinforcing bar and a deformed reinforcing bar depending on the presence of a node on the surface. Circular reinforcing bars mean that there are no nodes on the surface of the reinforcing bars, and deformed reinforcing bars have nodes and ribs. Generally, deformed reinforcing bars have more adhesive force with concrete than circular reinforcing bars, and cracks are less likely to crack when concrete is cracked.

Reinforcing bars are cut and bent in various forms at construction or civil engineering sites. They are combined horizontally and vertically to form a grid frame. In order to form these lattice frames, various shapes and a plurality of reinforcing bars have to be provided, and it is not easy to produce a large amount of reinforcing bars quickly and all in the same size and shape.

Conventionally, a device for conveying and bending a reinforcing bar has been disclosed. However, the device is manually operated. Even if the device can be automatically operated, the manufacturing speed is relatively slow and the user convenience is poor.

The present invention provides a reinforcing bar automatic processing apparatus capable of automatically picking up, transferring, bending and cutting a reinforcing bar.

The present invention provides an apparatus for automatically machining a reinforcing bar capable of improving work speed by simultaneously working a plurality of reinforcing bars in addition to a single number, and further capable of automatically picking up and transporting a predetermined number of reinforcing bars.

The present invention provides an automatic steel reinforcing machine capable of straightening and transporting, bending and cutting reinforcing bars automatically from a reinforcing bar material provided in a roll form.

According to an exemplary embodiment of the present invention, an automatic reinforcing bar machining apparatus includes a pick-up section for picking up a plurality of strands of reinforcing bars, a conveying section for simultaneously conveying a plurality of reinforcing bars picked up by the pick-up section, A position adjusting section for fixing the reinforcing bars to the programmed position, a reinforcing bending section for bending the reinforcing bars fixed by the position adjusting section from the ends, and a cutting section for simultaneously cutting a plurality of reinforcing bars bent by the reinforcing bent section. In particular, the reinforcing bending portion includes a center roller, a bending rod that rotates about the center roller, and a bending roller that is mounted on the bending rod so that the distance to the center roller can be adjusted.

The pick-up unit picks up a plurality of strands of reinforcing bars corresponding to the predetermined number from the plurality of reinforcing bars, and the picked up reinforcing bars of the plurality of strands are transferred to the position adjusting unit through the conveying unit. The position adjustment unit can simultaneously move forward or backward or fix the jammed reinforcing bar, and adjust the position so that the reinforcing bending portion can bend the reinforcing bar in a programmed shape. When the reinforcing bars are bent according to the programmed shape, the position adjusting unit moves the portion to be cut to the cutting point of the reinforcing bar cutting unit located adjacent to the position adjusting unit, and the reinforcing bar cutting unit cuts the position-adjusted cutting point.

Conventionally, the reinforcing bars are manually folded, but the automatic reinforcing bars of the present invention can be automatically picked up from the reinforcing bars, automatically bent and cut to improve the working speed. In particular, by simultaneously processing two or more strands of reinforcing bars, the speed can be further doubled.

According to another exemplary embodiment of the present invention, the automatic steel reinforcing machine includes a reinforcing bar providing a reinforcing bar in a roll form, a reinforcing bar bridging part for straightening the reinforcing bar supplied from the reinforcing bar providing part, A position adjusting section for fixing the conveyed reinforcing bars at a programmed position, a reinforcing bending section for bending the reinforcing bars fixed by the position adjusting section according to a programmed shape, and a reinforcing bending section And a cutting portion for simultaneously cutting the reinforcing bars of the bent plural strands. Again, the reinforcing bending section includes a center roller, a bending rod that rotates about the center roller, and a bending roller that is mounted on the bending rod so as to be adjustable in distance to the center roller.

The automatic reworking apparatus of the present invention can automatically perform picking up, transferring, bending and cutting of reinforcing bars.

The automatic reinforcing machine of the present invention can improve the working speed by simultaneously working a plurality of reinforcing bars, and can automatically pick up and transport a predetermined number of reinforcing bars.

The automatic steel reinforcing machine of the present invention can automatically withdraw a reinforcing bar from a reinforcing bar material provided in a roll form and automatically straighten, transport, bend and cut it, and can be omitted as a conventional intermediate processing .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments. For reference, the same numbers in this description refer to substantially the same elements and can be described with reference to the contents described in the other drawings under these rules, and the contents which are judged to be obvious to the person skilled in the art or repeated can be omitted.

FIG. 1 is a front view for explaining an automatic steel reinforcing machine according to an embodiment of the present invention, and FIG. 2 is a side view for explaining the automatic steel reinforcing machine of FIG.

1 and 2, a processing apparatus 100 according to the present embodiment includes a pickup 110, a transferring unit 130, a position adjusting unit 140, a reinforcing bar bending unit 150, a reinforcing bar cutting unit 170, .

The pick-up section 110 is provided with a reinforcing pile cut to a predetermined length adjacent to the pick-up section 110, and the pick-up section 110 can pick up a predetermined number of reinforcing bars S, for example, two or more reinforcing bars S from the reinforcing pile. The two reinforcing bars S are bound to the conveying unit 130 by the pick-up unit 110, and the reinforcing bars S are simultaneously conveyed by the conveying unit. The two reinforcing bars S conveyed by the conveying unit 130 are bound by the position adjusting unit 140.

The position adjustment unit 140 can interoperate with the transfer unit 130 and can operate independently. The position adjusting unit 140 fixes the reinforcing bars S transferred from the conveying unit 130 and adjusts the length of the reinforcing bars bent by the reinforcing bars bending unit 150 while moving the reinforcing bars S forward and backward. When the reinforcement S is initially fixed to the position adjusting unit 140, the end of the reinforcing bar S is cut by the reinforcing bar cutting unit 170. The ends of the reinforcing bars S can be made to coincide with each other by cutting the ends of the reinforcing bars S to a length of several centimeters so that the dimensions of the reinforcing bars can be accurately adjusted.

As described later, the position adjusting unit 140 and the reinforcing bar bending unit 150 can bend the reinforcing bars S in various shapes such as a quadrangle, a triangle, and a circle at the same time while operating according to the programmed process. When the shape of the reinforcing bar S is completed, the position adjusting unit 140 transfers the cutting point to the cutter of the reinforcing bar cutting unit 170, and the cut reinforcing bar structure is moved to another conveying unit or the lower part of the processing apparatus 100 .

Figs. 3 to 5 are views for explaining a pick-up section and a pick-up process in the machining apparatus of Fig.

Referring to FIG. 3, the pickup 110 includes an electromagnet pickup 112, and the electromagnet pickup 112 can simultaneously pick up several bars from a lower pile. The electromagnet pick-up 112 can pick up a predetermined number or more of reinforcing bars at the same time and transfer them to the conveying unit 130. [ The electromagnet pickup 112 may be designed to have magnetism at the time of pickup and to lose magnetism after transferring the reinforcing bars to the conveying unit 130. [

It may not be easy to accurately pick up a predetermined number of reinforcing bars by the electromagnet pickup 112 alone and the reinforcing rods of the raised reinforcing bars are easily engaged with the conveying rollers of the conveying portion 130 . In order to overcome this, the pickup 110 may further include an alignment roller 120.

The aligning roller 120 may include a threaded alignment groove 122 corresponding to the thickness of the reinforcing bar. Since the alignment groove 122 is formed in a threaded shape, the reinforcing bars S mounted on the alignment roller 120 can move in a predetermined direction, for example, inward, when the alignment roller 120 rotates.

The aligning roller 120 can switch its posture vertically and horizontally. The aligning roller 120 is in a vertical state until the electromagnet pick-up 112 picks up the reinforcing bars S and raises the reinforcing bars S to a predetermined height. When the electromagnet pickup 112 lifts the reinforcing bars to a predetermined height, the aligning roller 120 can be turned to a horizontal state. After switching to the horizontal state, the electromagnet pick-up 112 releases the magnetism so that the lifted reinforcing bars S are placed on the alignment roller 120. [

When several reinforcing bars S are placed on the aligning roller 120, the aligning roller 120 can rotate in a direction in which the reinforcing bars S are retracted. In this process, the reinforcing bars S along the alignment grooves 122 can move horizontally inward. Since the alignment grooves 122 are formed in a thread-like shape, the reinforcing bars S can be aligned while maintaining the pitch of the threads. Further, since the reinforcing bars S move in the direction in which they are retracted by the aligning roller 120, the ends of the reinforcing bars S can be positioned so as to coincide primarily with each other.

The alignment groove 122 of the alignment roller 120 may be formed with a uniform or non-uniform pitch. According to the present embodiment, the alignment groove 122 can be formed non-uniformly with a predetermined intention. For example, in order to distinguish two reinforcing bars from each other in the aligning roller 120, the interval between the aligning grooves 122 for the inner two-strand reinforcing bars and the outer aligning grooves 122 is wider than the average interval . Thus, the two strands of reinforcing bars and the other reinforcing bars can be kept physically wide apart.

The reinforcing bars S selected by the aligning roller 120 can be engaged with the selecting roller 114. [ According to the present embodiment, the selection roller 114 is formed with a width corresponding to the thickness of the two-strand reinforcing bars, and provides a concave roller surface for accommodating the two-strand reinforcing bars S, respectively. When the reinforcing bar S is a deformed reinforcing bar having a groove or a rib, a plurality of protrusions or teeth that can be engaged with a groove or a rib may be formed on the roller surface of the selection roller 114.

The two strands of reinforcing bars are aligned by the aligning roller 120 and the selecting roller 114 can transfer only the two strands of the reinforcing bars at the positions determined by the aligning roller 120 to the conveying portion 130. [ Here, after the selection roller 114 and the reinforcing bars S are engaged, the aligning roller 120 may return to the vertical state to enable the other electromagnet pick-up 112 to raise the other reinforcing bars.

The conveying roller 132 may also include a plurality of conveying rollers 132 and the conveying roller 132 may also provide a concave roller surface corresponding to each reinforcing bar, such as the selection roller 114. The conveying roller 132 can move two or more reinforcing bars at the same time, and the conveying roller 132 can also be provided by combining a single body or two rollers.

The conveying roller 132 may further include a calibrating roller 392 and a hydraulic actuator 394 to be described later so that the hydraulic actuator 394 can be used to automatically calibrate the reinforcing bars Can be included.

6 to 8 are views for explaining a position adjusting unit, a reinforcing bending unit and a reinforcing bar cutting unit in the processing apparatus of FIG.

6 to 8, the position adjustment unit 140 includes a holder 144 capable of adjusting and fixing the position of the reinforcing bars on the base 142 and the base 142. [ The holder 144 may include opposing adjustment rollers 146 and may include a concave roller surface to simultaneously move the two strands of reinforcing bars S and to prevent shaking of the reinforcing bars S, Two or more pairs of adjustment rollers 146 can be used.

In the position adjustment unit 140, the base 142 may be provided in an inclined state. The base 142 may provide a working surface of the reinforcing bar bending part 150 to be described later and the bending by the reinforcing bar bending part 150 may proceed on the inclined surface of the base 142. [ By inclining the base 142, the completed reinforcing bar structure can safely move to the floor along the slope, not the free fall.

Further, since the base 142 provides a sloped surface, the reinforcing bars can be supported by the inclined surfaces even in the process of bending the reinforcing bars by the reinforcing bars bending part 150, so that the reinforcing bars structure can be kept flat without being twisted. In particular, when the reinforcing structure is formed to have a width or length of about 1 m or more, distortion of the reinforcing structure can be effectively prevented. Of course, the base may be formed horizontally, but it may not be easy to move the reinforcing structure after completion if the base is horizontal.

The reinforcing bar cutting portion 170 is positioned adjacent to the position adjusting portion 140. The cutting unit 140 may be formed at the outlet of the position adjusting unit 140, and the cutting point adjusted by the position adjusting unit 140 may be accurately cut. The reinforcing bars 170 can cut the ends of the reinforcing bars that enter the first two strands, so that the ends of the reinforcing bars coincide at the cut surfaces and the dimensions are determined from the cut surfaces.

The reinforcing bar cutting unit 170 includes a cutter 172 that moves up and down at an exit of the position adjusting unit 140 and simultaneously rotates the two strands of reinforcing bars S simultaneously Can be cut.

The reinforcing bar bending portion 150 includes a center roller 152, a bending rod 154, and a bending roller 158. The bending roller 154 can be rotated about the center roller 152 by a programmed angle and the bending roller 158 is mounted on the bending rod 154 to simultaneously bend the two strands of reinforcing bar S in a desired direction . The bending rod 154 is provided with a longitudinally formed elongated hole 156 through which the bending roller 158 can be fixed while maintaining a variable distance relative to the center roller 152. The operator can adjust the position of the bending roller 158 according to the thickness of the reinforcing bar S.

In this embodiment, the roller surfaces of the center roller 152 and the bending roller 158 are flat and both rollers are provided to rotate freely, but in some cases, the roller surfaces of both rollers are also concave corresponding to the shape of the reinforcing bars And the rotation of the rollers can be controlled and operated.

FIG. 9 shows some examples of the reinforcing bar structure that can be processed by the processing apparatus of FIG. 1, and it is possible to form reinforcing bars of various shapes according to a program or setting condition.

10 and 11 are views for explaining an automatic steel reinforcing machine according to another embodiment of the present invention.

10 and 11, the reinforcing bar 200 according to the present embodiment also includes a pickup 210, a conveying unit 230, a position adjusting unit 240, a reinforcing bar bending unit 250, and a reinforcing bar cutting unit 270 ). The pick-up part 210 and the feed part 230 and the reinforcing bar cutting part 270 may refer to the description and the drawings of corresponding elements of the previous embodiment.

However, the reinforcing bending part 250 may be provided on both sides of the position adjusting part 240. The position adjusting unit 240 fixes the reinforcing bars S transferred from the transferring unit 230 and can cut the reinforcing bars S by a predetermined length. At this time, the two bars of reinforcing bars S can be cut at the same time by the reinforcing bars 270 positioned at the outlet of the primary position adjusting unit. Of course, if the reinforcing bars S are fixed to the position adjusting unit 240 for the first time, the ends of the reinforcing bars S may be cut by the reinforcing bar cutting unit 270, have.

First, the cut reinforcing bars S are fixed by a holder 244. The reinforcing bars 250 may be provided on both sides of the holder 244 and the holder 244 may be provided with an adjusting roller 246 facing each other and may be provided with concave And two or more pairs of adjustment rollers 246 can be used to prevent the sway of the reinforcing bars S. [

The position adjusting unit 240 and the reinforcing bar bending unit 250 may form a reinforcing bar structure having various shapes such as a U shape, a U shape, and a zigzag shape on both sides of the two reinforcing bars S while operating according to a programmed process. When the shape of the reinforcing structure is completed on both sides, the position adjusting section 240 can move the holder 244 to release the reinforcing bars S and move the inside of the base 242. The reinforcing bars S released from the holder 244 can move down along the slope of the base 242.

The reinforcing bar bending portion 250 includes a center roller 252, a bending rod 254, and a bending roller 258. The bending roller 258 can be rotated about the center roller 252 by a programmed angle and the bending roller 258 can be mounted on the bending rod 254 to simultaneously bend the two strands of reinforcing bar S in a desired direction . In some cases, the reinforcing bending portion may be mounted movably up and down on the base 242.

12 and 13 are views for explaining an automatic steel reinforcing machine according to another embodiment of the present invention.

12 and 13, the reinforcing bar machining apparatus 201 according to the present embodiment includes a pick-up portion, a conveying portion, a position adjusting portion 240, a reinforcing bar bending portion 250 provided on both sides of the position adjusting portion 240, .

The position adjusting unit 240 fixes the reinforcing bars S transferred from the transferring unit 230 and can cut the reinforcing bars S by a predetermined length. At this time, the two bars of reinforcing bars S can be cut at the same time by the reinforcing bars located at the outlet of the primary position adjusting unit.

First, the cut reinforcing bar S is fixed by a holder 244 and the reinforcing bar S bent by the reinforcing bar bending part 250 is loaded on the first loading barrel 280 along the base 242. When the reinforcing bars S are stacked in the primary stacking stage 280 and the reinforcing bars S are stacked over a predetermined amount, the primary stacking stage 280 is retracted downward and moved back to the secondary stacking stage 285 .

The worker can safely be protected from the falling reinforcing bars S by collecting the reinforcing bars S on the secondary stacking stage 285. The operator can safely protect the secondary stacking stage 285 through the first and second multi- 285), the reinforcing bars S can be arranged in a more orderly state.

For the multistage stacking, the primary stage 280 can function to temporarily load and pass the reinforcing bars S through an optional operation, for example, an operation of protruding or retracting relative to the base 242. [ Although not explicitly described, various structures that may be applied for the above mechanism of the primary storage bin 280 may be selected by those skilled in the art.

FIG. 14 is a view for explaining an automatic steel reinforcing machine according to another embodiment of the present invention. FIG.

14, the machining apparatus 300 according to the present embodiment includes a reinforcing bar providing portion 380, a reinforcing bar correcting portion 390, a position adjusting portion 340, a reinforcing bar bending portion 350 and a reinforcing bar cutting portion 370, .

The reinforcing bar 380 is provided with a reinforcing bar raw material in the form of a roll, and the reinforcing bar 380 may be provided while releasing the reinforcing bars in a circular shape. However, a circularly bent reinforcing bar (S) is not suitable for forming a reinforcing steel structure, and must undergo a straightening process. Also, in this process, it is very troublesome to straighten the reinforcing bars by straightening the reinforcing bars to a predetermined length and manually adjusting them again.

However, according to the present embodiment, when the reinforcing bars S pass through the reinforcing bridge section 390 from the reinforcing bar providing section 380, the reinforcing bars straightened straight by the reinforcing bridge section () And can be directly used as reinforcing bars (S) for the reinforcing steel structure.

Of course, it is possible to use one strand of reinforcing bars, but in the present embodiment, the reinforcing bars S are pulled out from the two-roll reinforcing bars and the two strands of reinforcing bars S are pulled out at the same time, It can be rough. By using the roll-shaped reinforcing bar immediately, the work can be continued without interruption, and the waste of disposal of the reinforcing bars (S) in the middle can be prevented because the intervals between the reinforcing bars (S) do not coincide with each other.

The reinforcing bridge unit 390 includes a plurality of pairs of straightening rollers 392 disposed in the path of the reinforcing bars S unwound from the reinforcing bars 380 and disposed on both sides or up and down around the reinforcing bars S. [ The straightening roller 392 may be provided above and below the path of movement of the reinforcing bars S and some straightening rollers 396 may be displaceably mounted by a hydraulic actuator 394 to straighten the reinforcing bars. At this time, the calibrating rollers 392 and 396 can control the rotation speed between the front and rear calibrating rollers or adjust the vertical height of the calibrating rollers so that the reinforcing bars automatically straighten.

At this time, the hydraulic actuator 394 automatically adjusts the height or the mutual displacement of the calibrating rollers 392 and 396 so that the operator can automatically adjust or change the displacement to match the straightening of the steel bar without controlling the displacement one by one.

The position adjustment unit 340 can interoperate with the calibration unit 390 and can operate independently. The position adjusting unit 340 fixes the reinforcing bars S transferred from the reinforcing bar adjusting unit 390 and adjusts the length of the reinforcing bars bent by the reinforcing bars bending unit 350 while moving the reinforcing bars S forward and backward. When the reinforcing bars S are initially fixed to the position adjusting unit 340, the ends of the reinforcing bars S are cut by the reinforcing bar cutting unit 370. The ends of the reinforcing bars S can be made to coincide with each other by cutting the ends of the reinforcing bars S to a length of several centimeters.

As described later, the position adjusting unit 340 and the reinforcing bar bending unit 350 can bend the reinforcing bars S in various shapes such as a quadrangle, a triangle, and a circle at the same time while operating according to the programmed process. When the shape of the reinforcing bar S is completed, the position adjusting unit 340 transfers the cutting point to the cutter of the reinforcing bar cutting unit 370, and the cut reinforcing bar structure is moved to another conveying unit or lower part of the processing apparatus 300 .

Although the present invention has been described with reference to the preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the following claims. It can be understood that
