Next, when the band guide guide table 306 is advanced by the guide table cylinder 321 to guide the band 103 supplied from the band hoop 104 of the dispenser reel 302, the dispenser reel 302 The band 103 is rotated to supply the band 103, and the band 103 is supplied onto the band guide guide table 306 and stops at the stop line while passing through the pinch roll 308 on the next guide table base 320. do.

When the band 103 supplied for the center calibration is on the left detection sensor 317, the band 103 is moved to the right side, and when the band 103 is provided on the right detection sensor 316, the valve 103 is moved to the left and the reel traverse 301 on the traverse table 314 is provided. The center sensing traverse 319 on the guide table base 320 operates to move the center, and the band 103 supplied by the center sensing sensor 318 at the rear end is finally calibrated to form a first band induction roll ( 315-1, 315-2) and the secondary band guide rolls 315-3, 315-4 continue to be guided through.

Subsequently, referring to FIG. 5, the band 103 supplied through the band guide rolls 315-1, 315-2, 315-3, and 315-4 is a top band guide chute 401 for binding (welding). ), And the top band 110 is bent upwardly as its tip is bent upward as the gate 406 is up by the bottom lifting band 111 and the gate lifting cylinder 407 for tangling. When the band 103 guided to the chute 402 and supplied by the top band sensing limit switch 409 is stopped, the top band induction chute 401 and the bottom are engaged to bond (weld) the bottom band 111. Top band 110 and down while being down by drum up-down cylinders 403-1 and 403-2 to which band fixing drums 405-1 and 405-2 provided in the front portions of the sub-band induction chute 402 are respectively connected. When the bottom band 111 is fixed to overlap, the spot welder 701 is operated to complete the binding (welding) operation, the spot welder 701 is home forge To return to.                     

When the binding operation is completed as described above, the bending machine 101 performs the normal bending operation in earnest.

In addition, when the bending work of the coiled product 100 is completed during the normal operation, the bending machine 101 returns to the home position, and this time point is the backward feeding time of the band 103. In order to prevent the loop 103 from being twisted or overlapped, the elastic guide roll 506 is operated by reading the loop generation value of the band 103 from the gear motor 703 during backward feeding. -1, 505-2 is moved up and down to adjust the elasticity of the band 103.

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this, The person of ordinary skill in the art to which this invention belongs, Of course, various modifications and variations are possible within the scope of the claims to be described below.

According to the present invention, as the device for automatically supplying the band hoop, band supply, band binding and band elasticity adjustment is provided, there is no need for manual work, and facilities due to band defects such as overlapping and twisting, and Problems in the progress of the work is overcome, it is possible to achieve the effect of improving the productivity of packaging work, reducing the operating load and ensuring worker safety.
