Abstract

PURPOSE:To make each reel replaceable easily without entailing wastage, by disposing a plural paired set of tape delivery reels and spare tape reels in a row, while setting up a tape winding head at the middle between them or the end part. CONSTITUTION:A tape 33 out of a tape reel 31 pivotally supported by a hollow main shaft 2 is guided by each of guides 34 and 35 and led into a tape winding head 37 from a guide 36 by way of the hollow main shaft 21. Hereat, the tape 33 passes through each of guides 41-43 on a disc 40 via each of guides 38 and 39 and then is rolled round on a cable core 44. On the other hand, a tape 47 out of another tape reel 46 is also rolled round on the cable core 44 in the same manner, And, when the tape of the reel 31 runs short by way of example, a piece of tape inside a spare reel 45 is transferred to the hollow main shaft 21 from a supporting hollow shaft 28 so that such a reel whose tape still remains inside is not required for replacement. Thus all tapes are effectively used without being wasted.

Description

[Detailed description of the invention] This invention relates to a concentric tape winding device.

When manufacturing cables and optical fiber tapes, a tape is wrapped around the core where the fibers are assembled to maintain its shape or for protection and insulation.This tape winding device has a tape pad that rotates around the outer circumference of the advancing core. There is a concentric type and a non-concentric type in which the tape pad rotates on its own axis while revolving around the cable core.The present invention provides a concentric type tape winding device that can efficiently wind multiple tapes. be.

To explain the conventional concentric tape winding device shown in Figs. 1 and 2, 1 in the figure is the winding head, 1 is the rotating f-axis,
2.2' is a bearing, 3 is a V-frame, and 4° is a pulley for rotating the main shaft, which is driven via a belt 5 by a drive device (not shown). 6 is a disk fixed to the rotating main shaft 1, on which tape guides 7, 8, 9, and 10 are installed. Reference numeral 11.12 denotes a tape reel, which is rotatably held on the rotating main shaft l by bearings 13.14. The bearings 13.14 are lightly braked by means of a device not shown, so that a braking force is exerted on the tape reel 11.12.

The tape guides 7, 8, 9, and 10 are pulled out with their respective pack tensions increased, and winding reaches a point. On the other hand, the cable core 19 is connected to the center hole 2 of the rotating main shaft 1.
0 and proceed in the direction of arrow A. By rotating the main rotational shaft l, the tapes 17 and 18 are wound helically around the outer periphery of the cable core 19.

In the conventional apparatus described above, the spare reel holder 15 is attached to the spare reel holder 15 before advancing the cape no core 19.

Particularly when there is a difference in tape thickness between both tape reels 11 and 12, replacing the tape reel becomes troublesome, and winding increases the number of tapes, which increases the complexity of winding.

This invention is intended to solve the above-mentioned problems, and its embodiment will be explained with reference to the attached drawings from FIG. is rotatably supported. 50 is a main shaft drive pulley which is driven via a belt 51. 24.
Reference numeral 25 denotes an elliptical disk fixed to the hollow main shaft 21, 22, and the outer circumferences of both disks are partially connected integrally by a lip 26.

28 is Speya! The support plate 27 fixedly supports the cylinder 26 with a support hollow shaft of J-/l/45.45'.
Hold the spare reel /l/45 on the l side and the spare reel 45' on the &2 side. The support plate 27 is provided with a hole 28 through which the tape passes.

A Cheaply/L/31 is rotatably supported on the hollow main shaft 21 by a bearing 32, and a light brake is applied by a brake device (not shown). The tape 33 unwound from the tape reel 31 is guided by tape guides 34 and 35 provided on the lip 26 and rotates around the shaft. 0. The tape winding is guided to the head 87 after passing through the hollow □-21 from the fixing point 36. The tape is wound on the spatula + '37 through tape guides 38 and 39 provided on the hollow main shaft 21, and then on the tape guide 4 on the disc 40 fixed to the hollow main shaft 21.

The guides 41', 42', and 48' are then wound around the cape flex core 44.

When one of the tapes of Cheaply/L/8-1.46 is consumed as described above, for example, when the tape on reel 31 is consumed, it is necessary to replace the smooth feed reel 46 at the same time. There isn't.

Similarly, when the tape on the reel 46 is used up, just move one Subearino 745' to the hollow main shaft 22, and there is no need to replace the reel 31 at the same time. Even if the tape has a different diameter, it can be used without wasting it, and leaf strips can be replaced very easily.

Although the above embodiment is a case in which two tapes are wound, even if the number of tapes is further increased, the same structure can be used, and the spare reel can be replaced for each tape.

In the above embodiment, the tape winding is carried out by head 37, /lL.
They are arranged in a line in the following order: o, 1 feeding reel -)v 31, its spare reel 45, high 2 Sveya reel/I/45', 2nd feeding reel,) v 46, but this l1if' For example, as shown in Fig. 6, t FF is the tape winding head 8'l, &, 1 side subeyary/L'

In short, a combination set of a feed reel and a spare reel is arranged in a line, and for tape winding, the head 37 is placed at both ends or in the middle of the combination set.The position of the head 37 for winding is determined by the operation. It can be determined based on the characteristics, rotation speed, and other conditions.

Furthermore, as shown in FIG. 8, the lip 26 is omitted, and the external drive device 52 connects and drives the winding throat 37 and the feeding reel 46 of the delivery reel 3.1. The position of the tape winding head can be arbitrarily changed as necessary.
