The present invention relates to an improved coil tip automatic taping device to reduce labor costs.

In general, since the coil produced in a rolled form is wound on a coil produced in a cold rolling mill, the tip of the rolled steel sheet is released by its own elastic force.

Hereinafter, the operation and effects of the coil tip automatic taping device 1 according to the present invention will be described in detail.

The coil tip automatic taping device 1 of the present invention is installed inside the coil car 100 so as to automatically unwind the coil tip before unwinding the coil 2 wound up in a tension reel (not shown). As a working device, this device is operated at the same time as the tip winding of the coil 2 is started in the tension reel after splitting the steel sheet in the exit shear.

That is, the coil tip is in contact with the snow roll 101 as the coil car 100 rises, and the coil tip is sensed by the proximity sensor 13 of the sensing unit 10 through the cutout 100a. The coil tip is positioned at the center of the coil car 100 by a pulse generator (PLG) of the tension reel. In this case, the idle roll 12 fixed to the plate 11 of the sensing unit 10 protects the proximity sensor 13 and prevents shaking of the steel sheet.

As described above, when the coil tip portion is positioned at the center of the coil car 100, the label stocker 51 and the winding roll 54 of the tape supply part 50 are rotated by the driving of the induction motor 55. The pulley motor 49 of the tape guide portion 40 is driven to rotate the round belt 45 connected to the plurality of pulleys 46 so as to be wound around the label stocker 51 and cut into sheets 3a. The attached tape 3 is separated by the angle of the guide roll 53, guided by the round belt 45 and the guide plate 41, and guided to the suction roll 36. At this time, the continuous label 3a separated from the tape 3 is continuously wound on a winding roll 54 in which the tip thereof is fixed by the fixing pin 54a.

In addition, the optical sensor 52 mounted near the label stocker 51 detects the winding amount of the tape 3 and informs the worker of the replacement time as a lamp and a buzzer, and the center of the guide plate 41. An optical sensor 43 mounted near the sensing groove 44 formed therein and detecting the presence or absence of the tape 3 guided to the outer circumferential surface of the adsorption roll 36 detects the tape 3, and at the same time, the air ring The suction air generated by the operation of the blow motor (not shown) is transferred to the adsorption roll 36 through the inner hole 43b of the swing arm 34 connected to the shield ball bearing 34a. Through the suction groove 36a of the guide will be able to adsorb the back of the tape (3) supplied.

At this time, one cycle rotation of the adsorption roll 36 rotated by the driving of the stepping motor 37 in the state where the tape 3 is adsorbed and attached is performed by the touch bar 36b of the proximity sensor 36c. It is stopped by sensing, and the outer circumferential surface length of the adsorption roll 36 is made larger than the sheet length of the tape 3 to be adsorbed, thereby preventing the tape 3 from overlapping.

On the other hand, after the tape 3 is adsorbed on the outer circumferential surface of the suction roll 36, the gears 33a and 33b are rotated by the driving of the gear motor 32, so that the swing arm is connected to the gear 33b. While the 34 is switched from the lowered position to the raised position, the suction roll 36 mounted at one end of the swing arm 34 is lifted to the upper side of the coil car 100 to be absorbed by the suction roll 36. The tape 3 is in contact with the coil tip. The up and down operation of the swing arm 34 is controlled by the rising position and the falling position proximity sensors 39a and 39b, respectively.

Therefore, when the swing arm 34 is detected by the rising position proximity sensor 39a, the stepping motor 37 is driven to rotate the suction roll 36 and at the same time, the worm is driven by the feed motor 24. As the transfer plate 26 connected to the gear 25 is advanced forward, the adsorption roll 36 attached with the tape 3 in contact with the coil tip is tapered while proceeding in the longitudinal direction. The work is performed until the tip touch bar 27a of the transfer plate 26 is advanced to the tip sensor 28a.

Then, as a detection of the tip sensor 28a, when the taping operation due to the rotation of the suction roll 36 is finished, the air ring blow motor and the stepping motor 37 are stopped, and the suction roll 36 is mounted. At the same time as the swing arm 34 returns to the lowered position, the transfer plate 26 is moved backward until the rear touch bar 27b is detected by the rear end sensor 28b by the reverse driving of the transfer motor 24. By repositioning, it is repositioned so that the taping operation of the next coil tip can be performed.

Accordingly, according to the coil tip automatic taping device 1 according to the present invention, the coil tip, which is dry-drained at the tension reel, is directly taped directly from the coil car 100 using the tape 3 adsorbed to the adsorption roll 36. By performing the work, it is possible to considerably reduce the overload of the worker rather than taping the coil tip by hand, and to reduce the labor cost by reducing the number of additional workers, while the productivity of work is greatly improved by the automation of the taping work. The effect of the phase is obtained.
