Since the separator tape material 10 is wound in a spiral shape, as shown in FIG. 3, the unwinding direction of the tape is a → b → c → b → a, and the direction of a or c remains unchanged. If it is tied to the winding position line, the tape material is distorted or twisted to lower the winding accuracy. Therefore, in the present invention, by combining this with a traverse mechanism and reciprocating the hanging shaft 11 in the direction of the arrow in accordance with the progress of winding, the winding direction of the tape is maintained in the direction of b. Always match the winding position line L.

The anode foil tape supply means uses the anode foil tape 20 as a hanging shaft 21.
Is a means for feeding and supplying the tape to the tape insertion roller 30 through the guide roller and the tension roller 22.
Further, the cathode foil tape supply means is means for feeding and supplying the cathode foil tape 40 from the hanging shaft 41 to the tape insertion roller 30 via the guide roller and the tension roller 42. Anode foil tape and cathode foil tape supply means,
Tabbing tools 23 and 43, respectively, are provided and tabbed so that when the tape is wound the tabbed tabs are within the same cycle. Further, the cutting tool 24 is provided in each of the means for supplying the anode foil tape and the cathode foil tape.
And 44 are provided, and the tape is cut after being fed to the tape insertion roller 30 by a predetermined length.

In the means for supplying the anode foil tape and the cathode foil tape, by closing and rotating the respective guide rollers 22 and 42 at the positions before reaching the cutting means 24 and 44,
The anode foil tape and the cathode foil tape are sent to the tape insertion roller 30 which is rotating and transferring the separator tape.

The tape insertion roller 30 consists of two rollers,
When this is closed, the separator tape, the cathode foil tape, the separator tape and the anode foil tape are laminated and wound in this order, and the laminated tape is sent to the winding means.

As shown in detail in FIG. 2, the winding means is located on the same circumference of the rotor 50 at an interval of 120 ° with respect to the center of the circle and is rotated by 120 ° in a certain direction. It consists of three winding shafts for winding the laminated tape at the position 51 of 1, winding stop at the second position 52, and removing at the third position 53. Separator cutting device 5 for cutting the separator tape between the two positions 52
A control mechanism is provided for performing S-shaped control on the rotational speed of the winding shaft at the fourth and first positions 51.

The laminated tape sent from the tape insertion roller 30 is the first
It is wound on the winding shaft at position 51.

When properly wound, the cutting instruments 24 and 44
Is activated, the anode foil tape and the cathode foil tape are cut.

The core axis around which the laminated tape is wound at the first position 51 is rotated by 120 ° and moved to the second position 52. At this stage,
The separator tape cutting device 54 operates to cut the separator. The end of the cut separator is held by a roller 55 attached to the cutting device 54.

The laminated tape wound around the winding core (hereinafter referred to as a laminated tape winding product) is sealed with the sealing tape 5 at the second position 52.
It is wound at 6.

Further, it turns to 120 ° and moves to the third position 53, where the laminated tape is extracted and dropped onto the chute 57.

As described above, the roller 5 at the first position 51 of the winding shaft is
5. The separator tape held in 5 and the wound anode foil tape and cathode foil tape are wound to form a laminated tape roll, and the laminated tape roll at the second position 52 is wrapped with a seal tape. Stopping, the withdrawal of the wound material in the pre-preceding stage at the third position 53 is performed simultaneously, and the work is performed in a continuous cycle.

The winding means of the device of the present invention is provided with a control mechanism for performing S-shaped control on the rotation speed of the winding shaft at the first position 51. When the winding is performed by rotating the winding shaft at a high speed in the conventional method, the rotation extremely changes at the acceleration point and the deceleration point, and the winding disorder occurs at that portion. The control mechanism is for preventing such winding disorder.

The automatic control means operates the separator tape feeding means,
The operation of the anode foil tape supply means and the cathode foil tape supply means, the opening and closing of the tape insertion roller, and the operation of the winding means are automatically controlled in cooperation with each other.
