(5) Electrical configuration of the winding device 10 The control unit 60 that controls the winding device 10 includes a computer, and rotates the rotation shaft 4 of the winding device 1, the rotation of the first shaft 7, and the rotation of the second shaft. To control. The control unit 60 includes a cutter support unit 18 of the cutting device 10, a cutter moving unit 20, an elevating unit 22, an elevating function unit of the rail 28, a first suction device (not shown) of the first suction unit 24, and a second suction unit 26. The second suction device (not shown) and the plate driving unit 42 are connected.

(6) Operating State of Winding Device 10 Next, the winding device 10 winds the web W from the first shaft 7 that is an old winding shaft to the second shaft 8 that is a new winding shaft, as shown in FIG. This will be described with reference to FIGS. 2 and 4 to 9.

  The first step will be described with reference to FIG. First, the wagon 58 is moved to move the splice roll 11 and the transport roll 64 to the winding position. The cutting device 10 and the lead roll 40 are moved to the lower cutting position by the plate driving unit 42. First, the lead roll 40 presses the web W downward. The web W is conveyed to the first shaft 7 through the lower peripheral surface of the transport roll 64, the upper peripheral surface of the splice roll 11, and the lower peripheral surface of the lead roll 40. The web W is not in contact with the plate body 12 and the second shaft 8. A double-sided adhesive tape (hereinafter simply referred to as “tape”) 66 is attached to the outer peripheral surface of the second shaft 8. In this state, the cutter 16 is housed inside the plate body 12.

  The second step will be described with reference to FIG. The control unit 60 stops the conveyance of the web W, and presses the plate body 12 to the second shaft 8 and the splice roll 11 by the lifting function unit of the rail 28. Then, the web W is fixed to the lower surface of the plate body 12 by the first suction part 24 and the second suction hole 26. The elevating unit 22 moves the cutter moving unit 20 downward, and causes the cutter 16 to protrude from the end of the slit 14.

  The third step will be described with reference to FIG. In a state where the web W is fixed to the lower surface of the plate body 12 by the first suction portion 24 and the second suction portion 26, the cutter support portion 18 rotates the cutter 16, and the cutter moving portion 20 moves the cutter support portion 18. The web W is moved in the width direction by moving along the slits 14 in the width direction. When the cutting of the web W is completed, the cutter support unit 18 stops the rotation of the cutter 16, and the elevating unit 22 moves the cutter moving unit 20 upward to store the cutter 16 in the plate body 12. In a state in which the cutter 16 is stored, the cutter moving unit 20 linearly moves the cutter support unit 18 to the initial position again.

  The fourth step will be described with reference to FIG. The first shaft 7 starts to wind up the rear end portion of the web W remaining after being cut. Further, the second shaft 8 is rotated in the winding direction, and the plate body 12 is moved along the rail 28 from upstream to downstream by the rotation. In this movement, the pinion 32 rotates following the movement of the plate body 12 and moves relative to the rack 30. Since the second suction unit 26 continues to suck the web W, when the plate body 12 moves, the web W follows the plate body 12 and the splice roll 11 and the transport roll 64 also rotate.

  The fifth step will be described with reference to FIG. When the second shaft 8 further rotates and the leading end of the web W cut to the position of the tape 66 arrives, the suction of the first suction unit 24 is stopped, and the leading end of the web W cut to the tape 66 is moved. Glue. The plate body 12 is in a state in which the web W is pressed against the second shaft 8 and the splice roll 11, and the second rotating shaft 8 continues to rotate, and the plate body 12 further moves from the upstream side to the downstream side. When the web W is bonded to the tape 66, the pressure function of the rail 28 releases the pressure bonding of the plate body 12 and stops the suction of the second suction part 26.

  The sixth step will be described with reference to FIG. The second shaft 8 further rotates to wind the web W. On the other hand, the first shaft 7 completely winds up the rear end portion of the cut web W. And the plate drive part 42 moves the lead roll 40 and the cutting device 10 to an upper standby position.

  The seventh step will be described with reference to FIG. When the web W is wound around the second shaft 8, the splice roll 11 and the transport roll 64 are replaced, and the winding amount of the web W increases. When the winding amount increases, the winding diameter of the web W increases, and at the same time, the wagon 58 moves toward the standby position, and the replaced transport roll 64 serves as a splice roll, and always presses the outer periphery of the web W. .

(7) Effect According to the present embodiment, the web W is cut upstream of the second shaft 8 that is a new winding shaft, and the front end portion of the cut web W is attached to the tape 66 of the second shaft 8. Therefore, the web W can be cut and wound efficiently on a new winding shaft.

  Further, when the web W is cut by the cutting device 10, the web W is cut in the width direction in a state where the web W is fixed by the first suction portion 24 and the second suction portion 2, so that the web W can be cut accurately.

  Further, when the web W is sucked by the lower surface of the plate body 12, the lower surface of the plate body 12 is sucked through the first rubber plate 48 and the second rubber plate 52. Can suck.

  Further, when the front end portion of the cut web W is bonded to the tape 66 of the second winding shaft 8, the plate body 12 moves with the rotation of the second shaft 8. It can be pressed and can be securely fixed to the second shaft 8.

(8) Modified Example In the above embodiment, the rotary blade of the cutter 16 is motor driven, but may be free driven instead.

  In the above embodiment, the cutter 16 is a rotary blade, but instead of this, a knife blade that moves linearly may be used.

  In the above embodiment, the lower surface of the plate body 12 is a flat surface, but instead of this, as shown in FIG. 10, a curved shape in which a central portion in the front-rear direction protrudes downward may be used.

  Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
