Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for removing a cable protective paper tape used in the process of manufacturing a high voltage power cable such as an SZ wire shielded cable.

[0002]

[Prior Art]

 For example, when manufacturing high-voltage power cables such as SZ wire-shielded cables, a protective paper tape is wrapped around the restraining tape in the wire-shielding process, and this is extruded to form the next sheath (sheath). It is peeled off during molding. In this case, since the peeling work is performed with the help of a person, when the protective paper tape is wrapped, the peeling thread is attached vertically between the holding tape and the protective paper tape, and the thread is pulled when peeling. Then, the protective paper tape is cut and peeled off.

[0003]

[Problems to be solved by the device]

 However, the protective paper tape is removed by hand as described above, and there is a problem in today's demand for more efficient work and labor saving.

Therefore, an object of the present invention is to realize the cutting and peeling of the protective paper tape by utilizing the movement of the cable when the cable is pulled out from the feeding drum, thereby making the cable manufacturing unmanned and labor-saving. It is an object of the present invention to provide a cable protective paper tape removing device that can be achieved and can improve work efficiency and productivity.

[0005]

[Methods for solving problems]

 The above object is achieved by the cable protective paper tape removing device according to the present invention. In summary, the present invention is provided with a cable receiving roller that is driven to rotate by the cable when a cable on which a peeling yarn is vertically attached and a protective paper tape is wound is pulled out from a delivery drum, and the cable receiving roller is The cable protective paper tape removing device is characterized in that the peeling yarn is taken by the interlocking take-up means, and the protective paper tape is cut and peeled.

【Example】

 Hereinafter, the cable protective paper tape removing device of the present invention will be described in more detail with reference to the drawings.

Referring to FIG. 1, one step in manufacturing a high voltage power cable such as an SZ wire shielded cable is illustrated. Fig. 1 shows a state in which a cable 2 in which a protective paper tape is wound around the outer side of the restraining tape in a wire shield step is wound around with a protective paper tape and is pulled out from the feed drum 3 to the caterpillar 1 in front of the extrusion crosshead. ..

The cable protective paper tape removing device 4 of the present invention is arranged between the feeding drum 3 and the front cross-caterpillar 1 of the extrusion crosshead. In this embodiment, the cable protective paper tape removing device 4 has a cable receiving roller 5 for holding the cable 2 pulled out from the feeding drum 3, as will be understood by also referring to FIG. The cable receiving roller 5 is supported by a pair of left and right bearings 6 in a horizontal state, and a peeling yarn take-up means is provided at the shaft end of the cable receiving roller 5. In this embodiment, the take-up means has a capstan roller 8 attached to the shaft end of the cable receiving roller 5 via a torque limiter 7. Presser rollers 9a, 9b and 9c are arranged around the capstan roller 8, and a tension belt 10 is stretched around these rollers.

The cable 2 pulled out from the feeding drum 3 passes through the cable receiving roller 5 and is fed to the extruder by the feeding crosshead front caterpillar 1. At this time, the cable receiving roller 5 is rotated in the moving direction of the cable by friction with the cable 2. When the cable receiving roller 5 rotates, the capstan roller 8 rotates, which causes the tension belt 10 to rotate together.

On the other hand, the peeling thread 15 provided on the cable 2 is sent to the capstan roller 8 via the guide loop 13, the guide reel 11, the guide loop 13, the guide reel 12 and the guide loop 14. Further, the peeling thread 15 is sandwiched between the capstan roller 8 and the tension belt 10 which rotate together. The capstan roller 8 and the tension belt 10 which rotate together forcibly pull the peeling thread 15, whereby the thread 15 cuts and peels the protective paper tape 16 wound around the cable 2.

If necessary, the pulled-out yarn 15 is contained in a bag or the like, and the peeled pieces of the protective paper tape are blown off by air or the like to be completely removed from the cable. Further, in the present embodiment, the reels 13 and 14 and the guide loops 11 and 12 are provided as the yarn withdrawing guide members for withdrawing the yarn 15 from the cable 2. You may adopt one.

Further, in the present embodiment, the diameter of the capstan roller 8 is set to be larger than the diameter of the cable receiving roller 5, and the tension is always applied to the peeling thread 15 drawn from the surface of the cable 2. I am doing it. The torque limiter 7 serves to prevent the tension applied to the peeling yarn 15 from being excessively cut.

[0013]

[Effect of the device]

 As described above in detail, the cable protective paper tape removing device according to the present invention, when the cable is pulled out from the feeding drum, the cable receiving roller supporting the cable is rotationally driven by the frictional force with the cable, and the cable is removed. By forcibly pulling out the peeling thread with a take-up device such as a capstan roller that interlocks with the receiving roller, cutting and peeling of the protective paper tape was realized, and in cable production, unmanned and labor-saving work was achieved. Efficiency and productivity can be improved.
