7, the guide block 322 is fixed to the upper surface of the lower forming part 320 and guides the reinforcing bar A conveyed from the conveying member 200 in one direction to the marking part 330 side. To this end, the guide block 322 forms a front surface and both side surfaces erected on the conveying member 200 side, and the back surface of the upper surface and the side of the marking portion 330 (or the bent portion 350) is opened.

Here, the front surface of the guide block 322 includes a guide hole 322b through which the coiled reinforcing bar A is moved.

The coiled reinforcing bars A are conveyed by the operation of a plurality of rotating rollers (not shown) provided in the conveying member 200 and are guided through the guide holes 322b of the guide block 322 and the moving rollers 323 . The guide of the guide block 322 has a distance between the conveying member 200 and the forming member 300. The reinforcing bars A can be linearly moved to the fixing portion 340 .

The fixing part 340 includes a bar-shaped fixing bar 341 extending downward from the lower surface of the upper forming part 310 and a fixing bar 341 fixedly mounted on the upper surface of the lower forming part 320 to stop and convey the coil- (Not shown).

The stopper 342 is formed of a horizontal surface on which the reinforcing bar A is positioned and a wall surface forming the upright surface, and is fixed to the upper surface of the lower forming portion 320. The end of the reinforcing bar (A) having passed through the marking portion (330) to the bent portion (350) is inserted into the upper surface of the stopper (342). Here, the reinforcing bar (A) is clogged on the upright surface to prevent the movement.

The fixing bar 341 is interlocked with the upper forming part 310 and presses the upper surface of the reinforcing bar A positioned on the stopper 342 while being lowered. The fixed bar 341 fixes the end of the reinforcing bar A to prevent the flow of the reinforcing bar A during operation of the bent portion 350 and the cut portion 360 to be described later.

Here, the fixing operation of the reinforcing bar (A) can be associated with the marking portion 330. That is, the marking portion 330 and the fixing bar 341 are spaced apart from each other with the bent portion 350 and the cut portion 360 interposed therebetween, respectively, so that the reinforcing bars A can be pressed, Can be fixed.

The marking unit 330 will be described with reference to FIG. 8 is a view showing the operation of the marking unit 330 and the front surface of the marking block.

8A and 8B, the marking unit 330 includes a pair of marking blocks 331 and 332 spaced apart from each other on a lower surface of the upper molding unit 310, a lower molding unit 320, And a pair of marking supporting blocks 333 and 334 for supporting the coil-shaped reinforcing bars A on the upper surface of the frame.

The first marking block 331 and the second marking block 332 extend downward from the upper ends of the pressure plates 331a and 332a and extend downward from the lower surfaces of the upper forming unit 310 And horizontal bodies 331b and 332b which are tightly fixed. That is, the first marking block 331 and the second marking block 332 have a shape of '┏'.

8 (c), the first marking block 331 and the second marking block 332 are upwardly cut from the lower ends of the pressure plates 331a and 332a to form coil-shaped reinforcing bars A And marking grooves 331c and 332c for cutting a part of the outer surface of the main body 331c.

The marking grooves 331c and 332c are cut upward at the lower ends of the pressure plates 331a and 332a, and the width thereof is gradually reduced. Therefore, the marking grooves 331c and 332c partially cut or deform the outer surface of the coiled reinforcing bar A drawn in between them.

The first marking block 331 displays the position of the reinforcing bar A cut by the cutter 360 and at the same time cuts or deforms the predicted point so that the cutter 360 can be easily cut.

The second marking block 332 displays the position of the reinforcing bar A bent by the bent portion 350 and deforms the reinforcing bar A at the corresponding position to facilitate bending.

Here, the first marking block 331 is cut and the second marking block 332 is used to mark the bending or to deform the reinforcing bar before bending and folding to facilitate the bending. The marking grooves 331c and 332c ) May be formed differently.

For example, since the marking groove 331c of the first marking block 331 is for indicating a cutting point, the upper side width of the marking groove 331c is larger than the marking groove 332c of the second marking block 332 Can be formed narrowly.

The pair of marking support blocks 333 and 334 are spaced apart from each other and have an upper surface capable of supporting the reinforcing bars A so as to facilitate marking on the upper surface of the lower molding part 320. [ The horizontal length and position of the marking support blocks 333 and 334 may be the same or smaller than the horizontal lengths 331b and 332b of the first and second marking blocks 331 and 332. Here, the positions of the marking supporting blocks 333 and 334 should be considered so that the lower ends of the pressure plates 331a and 332a are not caught.

 The marking support blocks 333 and 334 may thus include a first marking support block 333 positioned below the first marking block 331 and a second marking support block 333 positioned below the second marking block 332. [ 334 to support the reinforcing bars A marked by the first marking block 331 and the second marking block 332.

The marking supporting blocks 333 and 334 and the marking blocks 331 and 332 are connected together with the fixing bar 341 as described above to prevent the flow of the reinforcing bars A, have.

The cut portion 360 is raised and lowered between the marking portion 330 and the bent portion 350 to cut the reinforcing bar A. For this, the cutting portion 360 may include a cutter extending downward from the lower surface of the upper forming portion 310. The cutter generally employs a device used for cutting the reinforcing bar (A), so that detailed description and drawings are omitted.

The bent portion 350 will be described with reference to Fig. 9 is a perspective view showing a bent portion.

9, the bent portion 350 includes guide and support means 352 for guiding and supporting the reinforcing bar A, rotary pressing means 351 and rotary pressing means 351 for bending the reinforcing bar A, And a guide housing 353 rotatably supporting the guide housing 353.

The guide housing 353 supports the rotary pressing means 351 so as to be rotatable. Here, the guide housing 353 has a curved surface on one side to prevent the rotation pressing means 351 from being caught in rotation, more preferably, a rail capable of guiding the rotation pressing means 351 to the curved surface .

The guide and support means 352 is fixed at the front center portion of the rotary pressing means 351 to guide the conveyance of the reinforcing bars A and to cause the phenomenon that the reinforcing bars A are sprung by the pressure applied from the rotary pressing means 351 So that it can be prevented.

The guide and support means 352 is fixed at the front of the rotary pressing means 351 and is provided at the center of the reinforcing bars 351 to restrict the flow of the reinforcing bars A and to restrict the flow of the reinforcing bars A. [ A feed groove 352a is formed. The reinforcing bar transfer grooves 352a communicate with each other in the fore-and-aft direction to guide and support the reinforcing bar A.

The rotary pressing means 351 includes a pressing projection 351a for pressing against the reinforcing bar A at the front surface thereof. When the rotary pressing means 351 is rotated in one direction, the pressing projection presses and downwardly bends the reinforcing bar A extending to the inlet side of the guide and support means.

Here, the rotary pressing means 351 may operate in conjunction with the upper forming portion 310.

For example, the rotary pressing means 351 presses the switch positioned inside the main body of the rotary pressing means 351 and the rod-shaped sensing bar 351d extending downward in the upper forming portion 310 presses the switch, The rotary pressing means 351 can be rotated. At this time, the main body 351b of the rotation pressing means 351 may further include an insertion hole 351c through which the sensing bar 351d can be inserted from the upper surface.

Or the rotary pressing means 351 may be simultaneously driven together with the upper forming portion 310 and the cutting portion 360 by a single control of the control portion 510.

Wherein the rotary pressing means 351 is operated simultaneously with the cutting portion 360 and the marking portion 330 and / or the fixing portion 340.

For example, when the upper forming part 310 is lowered, the fixing bar 341 presses the end of the reinforcing bar A positioned on the stopper 342, and the marking part 330 is lowered, And the cut portion 360 is lowered in the region before the bent portion 350. As a result, The bending part 350 is rotated in one direction by the rotation pressing means 351 in conjunction with the cut part 360 and returned to the original position in connection with the rising and falling of the upper forming part 310.

Simultaneous operation of the bending part 350, the marking part 330, the cut part 360 and / or the fixing part 340 can be controlled by the control part 510, or the above- Such as the connection of the sensing bar 351d and the rotary pressing means 351 of the first and second sensors 310 and 310, respectively.

Further, in order to rotate the rotary pressing means 351 and return to the home position in conjunction with the lowering of the upper forming portion 310, the sensing bar 351d and the switch as described above may be used as a position sensing signal of the sensor, Can be implemented.

The present invention includes the above-described configuration. Hereinafter, the operation and effect of the present invention achieved through the above-described configuration will be described in detail.

FIG. 10 is a simplified view sequentially showing the operation of the forming member 300 according to the present invention.

10A, the coiled reinforcing bar A is wound on the outer surface of the winding means 120 as the rotary panel 150 is rotated by the driving of the rotary motor, and the winding guide means 130 are sequentially And is conveyed to the conveying member 200.

The reinforcing bar A is rotated by the rotation of rollers (not shown) of the conveying members 200 through the guide hole 322b of the guide block 322 formed on the upper surface of the lower forming part 320, 330, the cutting portion 360 and the bent portion 350 until the end thereof is stopped by the stopper 342.

Therefore, when the end of the reinforcing bar A reaches the stopper 342, the control unit 510 confirms this through the sensing signal of the sensor member 400 and stops the operation of the conveying member 200.

At this time, the coil-shaped reinforcing bars A are formed on the upper surface of the first marking supporting block 333 and the second marking supporting block 334 in the guide hole 322b of the guide block 322 and the upper surface of the guide and support means 352 And extends to the upper end of the stopper 342 through the feed groove 352a.

10B, when the end of the reinforcing bar A is positioned on the stopper 342 as described above, the upper forming part 310 is lowered by the power generated by the driving part 380. The first marking block 331 and the second marking block 332 of the marking unit 330 are positioned on the upper side of the first marking support block 333 and the second marking support block 334 of the lower forming unit 320 And at the same time, the cutter of the cut portion 360 is lowered. The rotation pressing means 351 of the bending portion 350 senses that the upper forming portion 310 is lowered and is rotated downward to a position where the pressing projection 351a contacts the reinforcing bar A. [

Referring to FIG. 10C, the support bars 311 of the upper forming part 310 are lowered to be in contact with the upper surface of the buffer cap 321a of the buffering part 321 of the lower forming part 320. At this time, the buffering means 321 relaxes the shock due to the elastic force of the spring 321b.

The first marking block 331 and the second marking block 332 are simultaneously extended to the upper surface of the first marking support block 333 and the second marking support block 334 along with the lowering of the upper forming part 310. [ The outer surface of the reinforcing bar (A) is scratched to indicate the bending position and the cutting position.

At the same time, the rotary pressing means 351 is rotated further downward than the preceding step to strike and press the outer surface of the reinforcing bar (A) positioned between the guide and support means and the cutter of the cut portion (360). Here, the position of the reinforcing bar A struck by the rotary pressing means 351 corresponds to the position indicated by the second marking block 332 in advance.

That is, the marking, the bending and the cutting are simultaneously performed according to the descent of the upper forming part 310. The marked reinforcing bar A is bent in the bent part 350 and the cut part 360 after the upper forming part 310 is elevated. So that cutting and bending are performed at the marked position when the next upper forming part 310 is lowered.

The cutting portion 360 also hits the marking marked position at the time when the pressing protrusion 351a of the rotary pressing means 351 is equal to or earlier than the time when the reinforcing bar A strikes the reinforcing bar A, It is preferable that the time difference between the cutting and bending is within 0.1 to 1.5 seconds, almost simultaneously.

The thus shaped reinforcing bar A 'is discharged through a discharge panel 370 to a designated place or enclosure 110.

Therefore, according to the present invention, since cutting, marking, and bending are simultaneously performed, the moving time and moving distance of the reinforcing bar (A) can be shortened, and the number of processes and manufacturing time can be greatly shortened.

It will be apparent to those skilled in the art that various modifications and equivalent arrangements may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Accordingly, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
