Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic terminal processing device for a cable having a synthetic fiber reinforcing layer such as Kevlar on the outer layer of a core wire such as an optical fiber.

(Prior Art and its Problems) When connecting a connector or the like to the terminal of a cable such as an optical fiber or a metal wire, a so-called stripping operation (terminal processing operation) is required. FIG. 20 shows the configuration of a single optical fiber cable C, in which the outer periphery of the optical fiber core (inner layer) L is used as a tensilan member, for example, an aromatic polyamide synthetic fiber (for example, Kevlar, Kevlar is manufactured by DuPont Co., Ltd. in the United States). The optical fiber core 1 is composed of a polyvinyl (PvC) jacket layer 3 interposed with a synthetic fiber reinforcing layer 2 such as (registered trademark of The outer periphery of the optical fiber 1a is made of silicon, urethane, etc. as a buffer layer, the primary coating layer (inner coating) lb has an outer diameter of 0.9+m, and the nylon fiber has an outer diameter of 2.0 mm. It is composed of a secondary coating layer IC such as polyethylene. In stripping the optical fiber cable C constructed in this manner, it is necessary to cut and remove not only the jacket layer 3 but also the coating layers 1c and lb of the core wire 1 to expose the optical fiber element 1ala.

This stripping work of cable C can be done using automated equipment using polyamide-based synthetic fibers (hereinafter referred to as
This is difficult to process (collectively referred to simply as "Kevlar"),
Traditionally, this was done manually using specially prepared tools to strip each layer.

This conventional method involves simultaneously cutting the outer layer 3 to the inner layer Kevlar 2 using a cutter that peels off the skin.
There is a method that attempts to remove Kevlar 2 as well as outer covering layer 3 at the same time. This method has a problem in that it is difficult to completely cut all of the Kevlar 2, and a portion of the Kevlar 2 remains uncut. The Kevlar 2 remaining uncut becomes an obstacle to the stripping work of the core wire 1.

As another conventional method, after cutting and removing the outer covering layer 3, the Kevlar 2 is folded back to the outer covering layer 3 side as shown in FIG.
The coating ji of the exposed optical fiber core l is fixed to the outer periphery of the
There is a method of cutting and removing lc and 1b. however,
This method also takes a long time to fix with the tape 4, and the peeling work time accounts for a large proportion of the total work time for terminal processing of the optical fiber cable C, which is a rate-limiting factor in the total work time.

Further, when the end of the optical fiber cable is manually stripped as described above, the cutting position of each coating layer is not constant, which poses a problem in terms of quality control.

The present invention has been made to solve these problems, and it is possible to perform the stripping work of optical fiber cables efficiently and reliably, to shorten the working time required for the stripping work, and to reduce the need for manpower. An object of the present invention is to provide an automatic cable terminal processing device that can be automated without any additional time, improve quality, and save labor.

A cylindrical body loosely fitted in the layer, a second gripping means for gripping an outer peripheral wall of the cylindrical body, and moved to a position where at least one of the outer covering layer and the inner layer is substantially cut. the first gripping means grips the cable and holds it in a predetermined position. The second gripping means grips and fixes the cylindrical body loosely fitted to the cable, and then the cutter means stops moving at a position where it substantially cuts the outer covering layer. After that, the first gripping means, while gripping the outer circumferential wall of the jacket layer of the cable, retreats to the other side to a position where one end of the cable is completely separated from the cylindrical body, and the outer jacket layer of the cable is moved back to the other side. A portion of the cable is cut and removed and the synthetic fiber reinforcing layer is exposed, the air nozzle blows air toward one end surface of the cable, the cutter moves back to the original position and stops, and the first grip is removed. After the means moves forward and stops again at the predetermined position, and then the cutter means stops moving at a position where it substantially cuts the at least one covering layer, the first gripping means moves around the outer periphery of the outer covering layer of the cable. Retreating to the other side while gripping the wall, cutting and removing a part of the coating layer to expose the strands, and when the first gripping means returns to the predetermined position again, the exposed and , the synthetic fiber reinforcing layer peeled off from the inner layer is folded back to the outer periphery of the outer covering layer on the other side of the cylindrical body, and the cylindrical body is attached to the outer covering via the folded synthetic fiber reinforcing layer. An automatic cable termination device is provided, the device being configured to be fitted over a layer.

(Function) When air is blown from the opposite direction to one end surface of the cable where the synthetic fiber layer is exposed, the synthetic fiber reinforcing layer is blown away to the side opposite to the one end surface of the cable, and the synthetic fiber reinforcing layer is Peel off everything from the inner layer.

In this state, when the cylindrical body is fitted around the outer periphery of the inner layer and the cylindrical body is moved toward the outer cladding layer, the synthetic fiber layer is folded back to the outer periphery of the outer cladding layer, and the cylindrical body covers the folded synthetic fiber layer. Since it is fixed to the outer periphery of the outer covering layer, the covering layer of the core wire is completely exposed and the stripping operation can be easily performed.
