Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application 1) The present invention provides the following features:
This invention relates to a device for simultaneously winding multiple pieces of tape or thread as protective insulation.

(Prior Art 1) A conventional concentric type tape or thread winding device for simultaneously winding a plurality of tapes is shown in Japanese Patent Laid-Open No. 124661/1983.

The conventional tape or thread winding device (hereinafter simply referred to as tape winding device) for simultaneously winding multiple tapes or threads (hereinafter simply referred to as tape winding device) will be specifically explained with reference to FIGS. 4 to 6.

In the figure, a rotating body 80 is rotatably supported via a bearing 5, and a braking device (not shown) applies a brake to the cough bearing 5, so that a braking force is applied to the tape pad 4. has been done.

The tape 22 is pulled out from the tape pad 4 under back tension, and is pulled out from the tape guide roller 11.
．． Guided by 12.13.14.15.16, the winding of the cable core 1 reaches a point.

On the other hand, the cable core 1 passes through the mounting hollow shaft of the rotating body 80 and runs in the direction of the arrow. Here, as the rotating body 80 rotates, the tape 22 is wound helically around the outer periphery of the cable core l.

The tape 22' has the same structure as the tape 22, and as a result, the tapes 22 and 22 are wound around the cable core 1 at the same time.

Further, 7 is a spare pad to be replaced when any one of the plurality of tape pads 4 is consumed.For example, when any one of the tape pads 4 is consumed, one of the spare pads 7 is replaced. It is used to transfer the tape.

[Problem to be solved by the invention]

In the conventional tape winding device, the rotating body 80 is
As shown in FIG. 4, whether integrated or separated, the rotary drive system is always integrated therewith.

Therefore, there were the following problems. Therefore, the 4th to 6th
Explain using diagrams; ■ Tape 22 to be wrapped depending on the type of cable core 1
The number of sheets of the rotating body 30 is different from each other, for example, even if one sheet is enough, the rotating body 30 is
It rotates and wastes rotational drive energy.

- When a plurality of tape pads 4 are used for simultaneous winding, the wear speed of each tape pad 4 is not the same, and it is necessary to replace the worn out ones with spare pads 7 one after another.

At this time, the rotation of the rotating body 80 is stopped and the replacement work is performed.
During this time, the line will naturally be in a stopped state, resulting in a decrease in manufacturing efficiency.

■When multiple tapes are wound simultaneously, the tape 22 may break due to some unpredictable factor. At this time, recovery work is required, but this work can take a considerable amount of time depending on how the tape is cut.

During this time, the line is in a stopped state as in the above-mentioned item 0, resulting in a decrease in manufacturing efficiency.

[Means to solve the problem]

The present inventors have adopted a configuration in which a coupling clutch is interposed between the tape winding section, each tape feeding section, and the rotational drive source in the tape winding device, so that the tape winding section and the tape feeding section can be separated and each The present inventors have discovered that it is possible to arbitrarily select the connection and disconnection from the rotary drive system, and have completed the present invention. That is, the present invention is: In a concentric tape winding device that winds a plurality of tapes, a tape winding section and a tape feeding section are each separated, and a connecting clutch is attached to each of them, so that they can be disconnected or connected. The present invention relates to a tape winding device characterized in that it is configured as follows.

The present invention will be specifically explained with reference to the drawings.

Figures 1 to 3 show an example of one piece of the present invention.

The winding head 10 is on the first frame 9, the first rotating head 8 is on the axis of the winding head IO, and the second rotating head 3 is on the second frame 9.
Each is held on the frame 2 via a bearing.

Further, the winding head lO1, the first rotary head 8, and the second rotary head 3 are rotated by the transmission shaft 21 and the rotary drive source 17 via the coupling clutches 18, 19, and 20, respectively.

The tape pad 4 is mounted on the shaft of the second rotary head 3 via a bearing 5. The bearing 5 is braked by a brake device (not shown), and the tape pad 4 is braked.

Further, the tape 22 is pulled out from the tape pad 4 under back tension, and is guided by the tape guide rolls 11, 12, 13, 14, 15, 16 to reach the wrapping point of the cable core 1.

A spare pad 7 for replacement is mounted on the spare pad holder 6.

On the other hand, the cable core 1 passes through the axes of the second rotary head 3, the spare pad holder 6, and the winding head 10 and runs in the direction of the arrow. Here, by the winding head 10, the first rotating head 8, and the second rotating head 3 rotating simultaneously,
A tape 22.22'' is each wound helically around the outer circumference of the cable core 1. In this case, the coupling clutch 18
．． 19.20 are all connected.

The coupling clutch used in the present invention includes a movement from the drive system,
Any clutch commonly used to connect and disconnect power, ie, drive energy, can be applied, but preferably an electromagnetic clutch is used, such as an electromagnetic clutch, a hydraulic clutch, a pneumatic clutch, a mechanical clutch, etc. Of course, the operation can be appropriately selected depending on the situation, whether automatic or manual.

Next, the case where one of the rotary heads is stopped using this coupling clutch mechanism will be explained using FIGS. 1 to 3.

First, the winding connects the connecting clutches 18 and 19 corresponding to the rad 8 to the first rotation of the head lO5, and disconnects the connecting clutch 20 corresponding to the second rotating head 3 by an appropriate control/switching mechanism. state, the winding head 10 and the first rotating head 8 rotate, and the second rotating head 3 rotates.
does not rotate, so attach only the 22" tape to cable core 1.
You can wrap it around the top or in between.
The tape pad 4 that is not rotating can be replaced with a spare pad 7.

[Effect]

The tape winding device of the present invention has the following effects: ■The device explained using the drawings can wind multiple tapes at the same time, but the number of tapes to be wound varies depending on the type of cable core, and for example, it can wind one tape. If it is good, only the portion necessary for winding one tape can be arbitrarily and easily selected and used.

Specifically, in FIGS. 1 to 3, when the coupling clutches 18 and 19 of the winding head lO5 and the first rotating head 8 are in the connected state and the coupling clutch 20 of the second rotating head 3 is in the disengaged state, the winding head 10. By rotating the first rotary head 8, only the tape 22" can be wound onto the cable core 1. In this case, since the rad 3 does not rotate during the second rotation, one member of the driving energy is lost. It can be prevented.

- When using the device to wind multiple tapes at the same time, the wear speed of each tape pad 4.4° is not the same (it is necessary to replace the worn pads with spare pads 7 in order).

At this time, only the worn out rotating head can be stopped while the other rotating heads and winding heads can be kept rotating, making it easy to replace the tape pad.

After completing the work, the rotary head is rotated again. This allows the line to be stopped in a short time.

Specifically, in FIGS. 1 to 3, when the tape head 4 is worn out, only the connecting clutch 20 is disengaged, the second rotary head 3 is stopped, and the tape head 4 is replaced with a spare band 7.

During this time, the winding head 10 and the first rotary head 8 are rotating. After the tape pad replacement work is completed, the second rotary head 3 starts rotating by bringing the connecting clutch 20 into the connected state again.

■Similarly, when using the device to wind multiple sheets at the same time,
The tape may break due to some unpredictable factor.

In this case, restoration work is required, but as in item 0, only the rotating head that caused the tape break can be stopped during the restoration work.

The above embodiments are for the case of multiple tapes, especially two tapes, but even if the number of tapes is further increased, the same structure can be used, and only a specific wrapped portion or unwinding portion can be separated by operating the connecting clutch. -Easy to connect.

In addition, in the above embodiment, the winding head, the first rotating head,
The spare pads are arranged in a line in the following order: to the tape, to the second rotation of the throat, to the rad, but the order is not limited to this.

〔Effect of the invention〕

As described above, the tape winding device of the present invention has a structure in which the separation of each tape winding section and tape feeding section and the disconnection and connection of each rotary drive system can be arbitrarily and easily selected. (1) By stopping the rotation of unused portions, energy saving of the rotational drive source can be achieved.

(2) The line stop period can be shortened, improving manufacturing efficiency.
