Abstract

PURPOSE:To take up strips formed of piled pieces divided in lateral direction tight to the reel cores by winding each strip around each reel core fixed around the same take-up axis and pressed in the axial direction with torque transfer plates. CONSTITUTION:Reel cores 14 fixed around a common take-up axis 12 are pressed in the axial direction by the torque transfer plates 16 placed closely in between the adjacent reel cores 14 and on the outsides of the two reel cores 14 located at both ends. Each reel core 14 is pressed by a common pressing roller 20 giving pressure on to the axis 12 through the wound strips 2. The pressure of the roller 20 is set greater than the frictional force between reel cores 14 and torque transfer plates 16; the take-up diameter of each reel core 14 is kept at the same level by the roller 20; the take-up velocity depends on the product of the take-up diameter and the angular velocity of the axis 12 irrespective of the thickness of any strips 1. Therefore, each coil will not be loosened.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to, for example, cutting one strip into two shapes using a slitter. The number of strips in one is 11
This invention relates to an improvement of a multi-strip winding machine that winds windings on a machine.

The strips formed by dividing one strip in the rb direction with a slitter are as good as the original strips. , it takes 1 minute to wind these on a multi-strip winder; the thickness of the strips formed by 1711 is not constant, so the winding machine can wind each strip. If each winding core rotates at the same speed, there will be a difference in the take-up speed of the nine strips. On the other hand, since the original strip material of +iii which is divided into one section is fed at a constant speed, the strip material with a large thickness is wound up under tension, and the strip material with a small thickness 4. ! There is slack in the winding 1j.I)-. Therefore, when winding up a 7-length L-<J< strip material, the length of the barrel b becomes longer than JP; 'l', causing problems in winding.

- In such a case, the winding rods are installed separately for each number of strips, and each
If you wind it up with 17 improvements, you can prevent sagging!
1- can be done, but this method requires a large floor area, increases equipment costs, and has the disadvantage of requiring an extra 11 hours of work since the divided strips are passed through the machine separately. . Historically, it has been possible to increase the number of volumes by allowing each winding core attached to a common winding shaft to slip in the direction of rotation, but this slip r11 is minute. This has the disadvantage that it tends to be unsteady, making it difficult to control.

An object of the present invention is to provide a multi-strip winding machine that can reliably wind each strip without increasing the body area or increasing equipment costs, without causing any slack. There is a particular thing.

,,1. Embodiments of the invention will be described in detail with reference to the drawings. Fig. 1 and Fig. 2 show a multi-filament winding machine 1 of the present invention.
1) 6 is shown, and this multiple winding machine 10 has a common winding 19 and 12
The four winding cores 14 attached to the serial number 1. Torque transmission plates 16 are arranged on the adjacent winding cores 14 and the outer surface of the outer winding core 14, and are pressed in the axial direction by non-illustrated spring means. The strip l, which is formed by dividing one strip in the m direction by slipping, is wound around each of these winding cores 14.

In particular, the multi-filament winder 10 of the present invention has five winders as shown in FIG.
A gap 18 is provided between the outer circumferential surface of the winding shaft 12 and the inner circumferential surface of each winding core 14 so that the winding core 14 can be eccentric based on the diameter of the strip coil. is equipped with a roller 20 that presses toward the center of the winding shaft 12 via a strip 1 wound around it. In addition, in this pressing, the pressing force of the roller 20 is applied to the winding core 14 and the torque transmission plate 1.
The force should be strong enough to overcome the frictional force between 6 and 6. In the illustrated embodiment.

In this pressing, the roller 20 may be located below the center of the strip coil 2, or may be located at another position.

In this way, the winding diameter R of each winding core 14 is always kept at -1 by the rolls 20.

- Since the force winding speed is determined by the product of the winding diameter and the angular velocity of the winding shaft 12, the values of the winding distance and the winding shaft 12 are constant for all strips regardless of the plate thickness, so there is no slack. will not occur. Note that if there is a gap 18 between the first winding shaft 12 and the winding core 14, the seventh winding core 14 will slip not only in the radial direction but also in the rotational direction. Because it is adjusted in a stable direction, pickpocketing of both parties,
It is possible to synergistically influence the winding speed to -.:C.

When comparing the body examples of the present invention with the comparative examples, 9 cases 9 have a plate thickness of 0.

The winding outer diameter of a thick plate coil is 1200 mm, while the winding outer diameter of a thin plate coil is 1196.82 mm. Therefore, the gap between the winding core and the winding shaft is 3.18 mm. That's enough.

According to the present invention, even if strips formed by dividing a strip having a plate crown are placed at the same time as shown in L, sagging does not occur, and since the winding 11 and the y-axis are common, the equipment It is small and requires less floor space - F has lower equipment costs.
