The present invention relates to an apparatus and a method for manufacturing a water-density body which can be manufactured by a method, which can reduce material costs, and save energy.
    In general, if water penetrates into the stranded conductor in the power cable, it may cause breakage accidents due to corrosion during use, which may shorten the cable life. Therefore, the gap between the conductor and the conductor should be filled with watertight compound or watertight powder. It can be prevented by filling in the form of a density body to prevent accidents.
    The first method of manufacturing the above water density body is a method of melting the watertight compound and injecting the stranded wire into the stranded wire while the stranded wire is stranded, and the second method is to make the center wire of the stranded conductor larger than the outer stranded wire in the space between the wires. The third method is to pressurize and fill the watertight compound. As a third method, the patent application No. 90-367 proposed by the present applicant processes the watertight compound on a tape, adheres it to each layer, and then forms the outermost stranded layer. Known.
    In addition, the present applicant has proposed a patent application No. 19-21589 for a device and a method of winding a watertight compound in the shape of a tape to a conductor and allowing the tape to pass through a heating device so that the watertight compound adheres to the conductor and is filled in the pores of the conductor. There is a bar.
    However, the first conventional method is not only difficult to sufficiently inject watertight compounds into the compression type conductor, but also has a problem that the stranded wire speed of the stranding machine is very low, resulting in poor productivity, and the molten watertight compound contaminates the work site and peripherals. There is a disadvantage that the second method is not practical and the third method is difficult to obtain sufficient watertightness.
    In addition, a method of wrapping a watertight compound in the shape of a tape in a watertight cable and passing the heating device has sufficient watertightness. There was a possibility that the high heat generated from the heating device can change the physical properties of the conductor, the cost of using the heating device in the production process was high, the heating device is expensive, the manufacturing cost was high.
    Accordingly, the present invention has been made in view of such circumstances, and an object thereof is to make the production cost of the water density body low, to simplify the device of the water density body, and to facilitate the production method.
    In order to achieve the above object, the present invention is to apply the adhesive to the water-absorbing body to twist the stranded conductor in the center line by the die of the twisting machine to the adhesive coating member, the powder supply member to the adhesive-coated density body By adhering the watertight powder to thereby remove the voids between the conductor and the conductor, the watertightness of the water density body is improved by a simple device, and the manufacturing cost is also reduced.

    In addition, the adhesive-coated water density body passes through the inside of the powder supply member to explain the step of filling the air gap between the stranded conductors of the water density body in detail as follows. First, the adhesive-coated water density body is guided by the guide hole of the guide and moved to the inside of the storage part of the powder supply member, and the water density body that has passed through the conductor hole packing of the water density body hole to be moved into the storage part has a circular center. The watertight powder is evenly adhered to the outer circumferential surface of the water density body by moving downward, and the watertight powder stored in the upper portion of the storage unit by the handle opening and closing of the lid is stored in the storage unit through the powder input unit of the powder stop, which is moved by the stopper knob. Afterwards, the adhesive is evenly adhered to the coated water density body so that the watertight powder is filled in the pores of the stranded conductor, and the watertight powder filled with the watertight powder passes through the conductor hole packing of the water density hole to separate the powder supply member by induction of the guide. It consists of the steps that make it possible.
    The present invention configured as described above will act as follows.
    First, as shown in FIG. 1, when the center line 11 or the water density body located in the center of the twisted pair machine 40 moves to the center of the plate 41 and the die 50, the outer circumferential surface of the center line 11 or the water density body The plurality of small conductors 13 are moved to the die 50 by passing through the plate 41 so as to be twisted. When each bobbin is rotated so that a plurality of small conductors 13 are twisted around the center line 11 or the water density body, the water density body 10 is shaped into a predetermined shape, and the water density body 10 is coated with adhesive. When moving to the lower side of the connecting tube 22 of the member 20, the water density body 10 is able to receive the adhesive 27 from the connecting tube 22.
    As shown in FIG. 3, when the water density body 10 formed by the stranded wire moves to the adhesive coating member 20, the adhesive 27 is supplied from the connection pipe 22 of the adhesive coating member 20. In other words, the adhesive 25 is inserted into the body 21 of the adhesive coating member 20, the upper portion of which is opened by the cover 24 provided on the upper side. At this time, the adhesive 27 is sufficient if the watertight powder 60 can be adhered to the water density body 10. The adhesive 27 inserted into the body 21 is applied to the water density body 10 through the connecting pipe 22. At this time, by adjusting the valve 23 of the connecting pipe 22, it is possible to control the amount of adhesive and prevent the flow of the adhesive. In addition, since the height of the adhesive coating member 20 is adjusted by the support 26, the tip end portion of the connecting pipe 22 is positioned above the water density body 10. Therefore, two connecting pipes 22 are formed in the water density body 10 at regular intervals, and the movable adhesive 27 moves on the surface of the water density body 10 so that the entire outer circumferential surface of the water density body 10 is even. It is possible to apply.
    The powder supply member 30 as shown in FIGS. 4 to 6 is to adhere the water-tight powder 60 to the water density body 10 as follows. That is, when the water density body 10 coated with the adhesive 27 is inserted into the guide hole 35b of the guide 35, the water density body 10 is stored through the conductor hole packing 34a of the water density hole 34. It is inserted into the inside of the part 31. At this time, since the water density hole 34 is provided below the center of the circle, the water density body 10 inserted through the water density hole 34 is formed at the upper portion of the storage part 31 having a lower shape. Of course, the watertight powder 60 may be continuously supplied to the lower side and may be bonded to the surface of the water density body 10. In addition, the water density body 10 may be inserted into and separated from the powder supply member 30 while maintaining the predetermined height by the guide of the guider 35.
    In order to prevent the water-tight powder 60 from being supplied to the water density body 10, the powder input part 32b is pulled out so that the stopper knob 32a of the powder stopper 32 is pulled out. If it is to be separated to the outside of the body of the powder stop (32) it is possible to prevent the movement of the water-tight powder (60). In addition, it is possible to adjust the height of the storage part 31 by the height adjustment tool 36a, thereby making it possible to adjust the height of the water density body hole 34 of the storage part according to the height of the water density body 10. do.
    When the water density body 10 passes through the powder supply member 30 as described above, the adhesive 27 applied to surround the outer circumferential surface of the water density body 10 adheres the watertight powder 60 as shown in FIG. 2. Thus, the watertight powder 60 may fill the air gap 12 generated by the small conductor 13. In addition, the above process can be carried out on the outer circumferential surface of the center line 11, can also be carried out on the outer circumferential surface of the small conductor 13 wrapped around the center line 11, the above-described device on the outer circumferential surface of the stranded conductor 13 It is possible to bond the watertight powder 60 by the method. Therefore, it becomes possible to wrap the space | gap of each stranded conductor 13 also in several layers of the water density body 10 by the said method.
    The water density body formed as described above constitutes a watertight cable coated with a plurality of coating layers on the outer circumferential surface. The watertight cable is subjected to a watertight test. That is, it is a test to determine whether water leaks after immersing only the water-dense material which peeled the said coating layer in the inside of a water tank of 1 atmosphere, and leaving it for 24 hours in the state which exposed the other side which did not remove the coating layer. In the watertight test of the water-tight body produced in accordance with the present invention was confirmed that the water does not leak out.
    The present invention as described above has the effect of simplifying the device of the density body, and the production method is easy.
