The operation and effects of the present invention having the configuration as described above will be described.

When the raw material coil 107 is seated on the skid 106 of the conveyor facility 105 for hot dip galvanizing of the steel sheet, the operator uses a control panel (not shown) such as a DCS (Direct Control System) terminal inside the cab. The skid 106 is conveyed step by step so that the material coil 107 is mounted on the payoff reel 108 by sending an electrical signal. When the conveyed skid 106 comes to the position where the device 1 of the present invention is installed, the operator sends an electrical signal to the control valve 35a for supplying a fluid from the operation panel to the first cylinder 12 side, thereby providing the first signal. The rod end of the cylinder 12 is moved forward.

In this case, as shown in FIGS. 6 and 7, the operating table 11 connected to the first cylinder 12 pivots the cutting case 13 of the upper end toward the material coil 107 on the skid 106. The rear end of the touch bar 14, which is in contact with the outer surface and is pivoted together with the operating table 11 and whose tip is in contact with the outer surface of the material coil 107, is in contact with the second touch sensor 31b to generate a detection signal. Until the turning operation of the operating table 11 by the forward operation of the first cylinder 12 is continued.

Then, when the cutting motor 16 is rotated in the forward direction by the second touch sensor 31b, the cutting operation for the band 8 of the material coil 107 facing the inner side of the cutting case 13 is performed. Is done. That is, when the screw shaft 15 connected by the cutting motor 16 and the power transmission means 17 is rotated in the forward direction, the moving blocks 15a and 15b assembled at both ends thereof are guided along the guide rail 13a0. Since it is gradually closed inwards, the holders 18a and 18b installed in the movable blocks 15a and 15b are in contact with and fixed to both outer edges of the band 8 to be cut, and thus the band 8 ), The band 8 is cut when the retracting operation of the movable blocks 15a and 15b is further progressed so that the knife members 19a and 19b installed therein intersect with each other. Retraction operation of the moving blocks 15a and 15b is continued until the proximity sensor 33 of the one fixed bar 32a respectively installed thereto moves closer to the tip of the other fixed bar 32b to generate a detection signal. The cutting mother by the detection signal of the proximity sensor 33 generated at the same time as the cutting of the band (8) The forward rotation of the rotor 16 is stopped, and the first cylinder 12, which has been operated forward, is reversely operated by the selective fluid supply of the control valve 35a to return the operating table 11 to its original state. .

In this case, the touch bar 14 of the operating table 11 that is returning operation is also forcibly returned to its original state by the return spring 14a that is expanded in the contracted state, and the rear end thereof contacts the first touch sensor 31a to detect the detection signal. And an electric signal is transmitted to another control valve 35b by this signal, and when the second cylinder 22 is moved forward, the operating arm 23 having the driven roll 24 mounted at the tip is upward. Since the swinging operation is performed, the band 8, which is cut off as the knife members 19a and 19b and whose tip is held between the holders 18a and 18b, is lifted and the driven roll 24 is raised. The first driving roll 25b of the case 24 is squeezed.

Subsequently, when the electric motor sends the electric signal to the cutting motor 16 in the cab to discharge the cut band 8 in reverse direction, the screw shaft 15 is rotated in the reverse direction as described above, so that the moving block 15a ( 15b) is moved to the left and right sides to free the band 8 held by the holders 18a and 18b, and in this state, an electric signal is temporarily sent to the first discharge motor 25a to allow the band 8 to be freed. When the first driving roll 25a is reversely rotated such that the front end of the 8 moves to the material coil side, the band 8 is reversed a little so that the front end of the discharge guide 25 of the discharge case 25 is opened. In this case, when the electrical signals are simultaneously sent to the first and second discharge motors 25a and 26a and rotated in the forward direction, the first and second drive rolls 25b and 26b connected thereto are in the forward direction. While rotating to, narrow between the first driving roll (25b) and the driven roll (24) Pulling the band (8) it is guided into the exhaust guider (27).

Accordingly, the tip of the band 8 which is driven by the forward rotational driving of the first driving roll 25b and the driven roll 24 and discharged is rotated with the rear curved portion 25c of the discharge case 25. When the traveling direction is switched directly below the second driving roll 26b, and the tip of the switched band 8 reaches the arc groove 28, the first driving roll 25b and the driven roll 24 The band 8 cut by the force pushed by the discharge force and the rotational force of the second driving roll 26b is wound in a coil shape as shown in FIG. 7, and then drops downward through the discharge chute to discharge. Will be processed. At this time, the discharge chute 29 is provided with a discharge sensor 34 having a discharge check touch bar 34a, so that the coil-shaped band 8 discharged through the discharge chute 29 is the discharge sensor. It is detected at 34. In response to the detection signal of the discharge sensor 34, the rotational driving of the first and second discharge motors 25a and 26a is stopped, and the control valve 35b so that the rod end of the second cylinder 22 is returned backward. By returning the descending operating arm (23) by sending an electrical signal to the end), all the cutting and discharging work of the band (8) wound on the material coil 107 is finished, to wait for the next band cutting work do.

According to the present invention having the configuration as described above, the knife of the moving block (15a) (15b) of the band (8) wound around the outer peripheral portion of the material coil 107 is pinched by the cutting motor 16 Simple and safe cutting as the members 19a and 19b. The cut band 8 is guided to the circular groove 28 as the driven roll 24 and the first and second driving rolls 25b and 26b. Since it can be wound in the form of a roll and then scraped through the discharge chute 29, the band cutting work and the scraping of the cut band 8 can be safely and conveniently performed to improve work productivity and prevent safety accidents. That a substantial effect is obtained.
