Abstract

PURPOSE:To automate feeding of a cable core and accomplish unmanned operation by installing a core feeding device. CONSTITUTION:A cable core 2 fed from a core feeder drum 1 is pinched by a core feeding device 9 and drawn out to above a pipe shaping tool 5. A metal tape is supplied from a tape supply reel 3, supported by a tape guide loading 11, passed via a tape washing device 4, and shaped into pipe form by the tool 5. The cable core 2 fed just in front of the tool 5 actuates the core feeding device 9 with a switch on an operation board 10 and is fed in such an attitude as embraced by the pipe shaped by the tool 5. The pipe embracing the core 2 is welded in longitudinal direction by a welding torch 6 continuously and taken up by a takeup capstan 7. Therein, caterpillars 9 are synchronized in speed with the take-up capstan 7. This simplifies the works and allows achieving unmanned operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable manufacturing method capable of simplifying work and saving labor.

[0002]

2. Description of the Related Art An overall view of an example of a conventional metal coating production line is shown in FIG. 3, in which two cable cores sent from a core sending drum are metal tapes sent from a metal tape sending reel of three. The center of the pipe forming tool of No. 5 is vertically covered so that it is wrapped in a metal tape. The metal tape delivered from the metal tape delivery reel 3 is washed by the washing device 4 and
It is rolled into a pipe shape with the pipe forming tool of, and immediately after that, the butt portion of the tape is continuously welded in the longitudinal direction while holding the cable core. The tube is picked up by a take-up clamp capstan 7 and corrugated and made flexible by a corrugating ring 8.

By the way, the cable core 2 is artificially pulled out from the core feeding drum 1, the metal tape feeding reel 3 and the upper portion of the tape cleaning device 4 are pulled out and placed in the center of the line, Is stopped during setup on the pipe forming tool of 5.

At the beginning of the work, after the pipe forming work of the metal tape is started, the operator manually assists the rotation of the core feeding drum, the end of the core and the cleaning device, and the cable core is drawn into the pipe. Has been done.

However, this conventional manufacturing method has a drawback that a large number of personnel are required to pull out a heavy cable core.

Further, the drum, which is heavy and has a long cable wound, has a flange diameter of 2000 mm or more, and the operator who rotates it at the start of work is physically burdensome and dangerous. there were.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks of the prior art, and to provide a novel cable manufacturing method capable of automating the feeding of the cable core and saving labor.

[0008]

The gist of the present invention resides in that a core feeding device is installed for feeding the cable core, thereby greatly improving workability.

[0009]

1 shows an embodiment of the method of the present invention.
The cable core 2 sent out from the core sending-out drum 1 is sandwiched by the core sending-in device 9 and drawn out to the upper part of the pipe forming tool 5. The metal tape is delivered from the metal tape delivery reel 3 and is supported by the tape guide roll 11 and passes through the cleaning device 14 and
It is molded into a pipe shape with the pipe forming tool of No. 5. The cable core that has been sent up to immediately before 5 is sent so as to be held in the pipe molded at 5 by activating the sending device at 9 by the switch on the operation panel at 10. The pipe is continuously welded in the longitudinal direction by the welding torch 6 while holding the core. After that, the pipe is taken up by the clamp capstan 7 but the caterpillar 9 is speed-tuned with 7, so that the core feeding is neither too early nor too late. The pipe is corrugated with 8 corrugation rings to give flexibility.

FIG. 2 is a sectional view showing a state where the core feeding device according to the present invention is fed while sandwiching the cable core. The hollow rubber getter 13 is attached to the receiving plate 12 and the contact surface of the rubber getter does not escape to the inner hollow portion and flatten the cable core even if the hollow rubber getter 2 sandwiches the cable core 2.

[0011]

As described above, conventionally, when pulling a heavy cable core, five core pulling personnel are always required, but according to the method of the present invention, the pulling work is performed by one operator. It is possible to simplify the work and save labor, and its industrial value is great.
