That is, the chuckers 720 and 730 are transported by the cylinder 710 while the rebar 1 is chucked to stack a plurality of rebars 1 sequentially on the bottom surface of the base 10 as shown in FIG. 7. will be.

Referring to the operation of the rebar supply apparatus according to the invention configured as described above are as follows.

First, the reinforcing bars 1 are supplied to cross each other by the first and second reinforcing bar supply means 100 and 200.

That is, a plurality of reinforcing bars 1 stacked on the upper surface of the guide plate 110 constituting the first reinforcing bar supply means 100 are supplied to each of the reinforcing bars one by one through the vibration motor 120 and the brush 130. Through the cylinder 330 and the guide plate 330 constituting the means 300 is supplied to the portion adjacent to the second reinforcing bar supply means 200.

At this time, through the second reinforcing bar supply means 200, the reinforcing bar 2 is supplied in a direction perpendicular to the supply direction of the reinforcing bar 1 through the first reinforcing bar supply means 100, and as a result, the second reinforcing bar supply means 200 ) And the reinforcing bars 1 on the upper surface of the adjacent base 10 are positioned to cross each other.

When the reinforcing bars 1 are positioned in such a manner as to intersect with each other, the first binding means 400 binds them.

That is, the bundling line 440 supplied while being stacked on the supply block 430 is supplied upward through the guide groove 422 of the guide block 420 by the pressure bar 460, so that the rebar 1 Both ends are positioned to be exposed to the intersection, and at the same time, the binding band 470 is moved inward from both sides of the guide groove 421 of the guide block 420 to press the both ends of the binding line 440 to cross the rebar ( 1) are bound together.

On the other hand, the temporary binding operation is to be carried out at all the intersections of the bars (1) bar for this purpose, the reinforcing bars (1) to be bound to be transported by a predetermined pitch by the second transfer means 500 while the temporary binding operation Is done.

That is, the guiders 520 and the supporters 540 on the fixed blocks 510 and 530 holding the reinforcing bars 1 by the operation of the cylinder 550 constituting the second conveying means 500 are pitched by a predetermined pitch. By moving, the binding operation is performed by a predetermined pitch.

As such, when the temporary binding operation is completed, the reinforcing bars 1 are completely engaged through the second binding unit 600 to stabilize the binding force.

That is, by pressing the finger pair 650 constituting the second binding means 600 through the pressure block 670 to pressurize and support the binding line 440 in the temporary binding state and at the same time the finger through the feed screw 630 By rotating the pair 650 a predetermined number of times, the complete binding is achieved.

At this time, the plurality of feed screw 630 for rotating the finger pair 650 is rotated in a direction opposite to each other, so that even if any one of the binding state is released, the other binding portion maintains the binding state by the impact from the outside The release of the binding state can be prevented in advance.

Thus completely bound reinforcing bars are sequentially stacked on one side lower surface of the base 10 by the stacking means (700).

That is, the rebar 1 is chucked by the chuckers 720 and 730 and transferred through the cylinder 710 to be stacked on the lower surface of the base 10 by a predetermined height.
