Description

  The present invention relates to a crossover cable used for contactless transmission of signals and a method for manufacturing the same.

  Non-contact transmission of signals is indispensable for exchanging information such as stop positioning and position confirmation of mobile objects such as carriers in automation factories and three-dimensional warehouses. There are various systems for performing contactless transmission, but it is common to attach a loop antenna to a moving body and a pair of crossing cables to the moving route.

  In the conventional crossover cable, as shown in FIG. 11, two insulated core wires 112 are connected by a joint portion 113 at a predetermined interval, a slot portion 114 is provided at a predetermined interval, and a crossing portion 115 is formed at a predetermined pitch. ing. In contactless transmission of signals, the interval between the insulated core wires 112 and the crossing pitch play an important role in order to accurately receive the change in the reception level. For this reason, the position of the intersection 115 is fixed by the adhesive tape 116, and the intersection pitch is accurately maintained.

  In the manufacturing method of this crossing cable, first, in the manufacturing apparatus 121 shown in FIG. 12, the two conductors 124 sent in parallel from the sending apparatus 123 reach the extruder 126 through the guide roll 125, and a predetermined gap is provided between the conductors. An insulating layer having slit portions 114 formed at intervals is extruded to form a two-core parallel cable 122, cooled in a water tank 127, and then taken up by a take-up device 128 such as a pinch roller or a capstan. Then, it is wound around the drum by the winding device 130.

  Next, in the manufacturing apparatus 131 shown in FIG. 13, the two-core parallel cable 122 is delivered by intermittently twisting the delivery device 132. The crossed cable base 135 having a twist in the slit 114 of the two-core parallel cable 122 reaches the workbench 136 through the guide roll 134, where the apparatus is stopped once, and on the workbench 136, the crossed cable base 135 The adhesive tape 116 is affixed to the crossing part 115 by manual work, and the crossing part 115 is fixed. When the adhesive tape 116 is applied to all the intersections 115 on the work table 136, the apparatus is operated again. When the intersection 115 is located on the work table 136, the apparatus is stopped and the adhesive tape 116 is applied. By repeating this, the conventional cross cable 111 is completed. After that, it is wound around a drum by a winding device 138 through a winding inlet guide 137 (recording with a reel is no problem).

  The prior art document information related to the invention of this application includes the following.

This is a method in which the insulating cable 4 of the parallel cable 33 is crossed at the slot portion 6 and is integrated by being sandwiched from both sides by fixing tapes 7a and 7b.

  Since the crossing cable 1 is integrated with two fixing tapes 7a and 7b across the entire line, the adhesive tape attaching work that has been done manually can be mechanized in-line, the work efficiency is very good, and it is safe. The potential increases.

  Furthermore, it is possible to maintain the accurate pitch d4 of the intersecting portion 8, and to maintain the accurate pitch d4 of the intersecting portion 8, such as variations in the pitch d4 of the intersecting portion 8 and the wrinkles of the adhesive tape, which have conventionally occurred due to manual work.

Claims (6)

  A crossing cable formed by crossing two insulated conductors parallel to each other at a predetermined interval and used for non-contact transmission of a signal; a connecting portion for connecting the two insulated conductors; A slot portion formed at a predetermined interval along the longitudinal direction of the connecting portion and having an intersecting portion that intersects the two conductors covered with insulation; the two conductors covered with insulation; the connecting portion; and A crossover cable comprising two fixing tapes that are integrated with the slot portion sandwiched in the longitudinal direction.   The crossover cable according to claim 1, wherein a distance between the two conductors is 6 to 12 mm, a length of the slot portion is 20 to 250 mm, and a pitch of the crossing portion is 40 to 500 mm.   The crossover cable according to claim 1 or 2, wherein the connecting portion is made of polyethylene, and the fixing tape is made of a plastic tape and an adhesive layer.   In a method of manufacturing a crossed cable formed by crossing two parallel conductors coated with insulation at a predetermined interval and connecting the two conductors coated with insulation in a method of manufacturing a crossed cable used for non-contact transmission of signals Slot portions are formed at predetermined intervals along the longitudinal direction thereof, the two conductors coated with insulation at the positions of the slot portions are crossed, and then the two insulation coatings are continuously formed. A method for producing a crossover cable, wherein the conductor, the connecting portion, and the slot portion are integrated by being sandwiched from both sides by two fixing tapes in the longitudinal direction.   After forming the slot portion, a first step of winding the two conductors coated with insulation around a drum or a reel, and sending out the two conductors wound around the drum or the reel while twisting, 5. The second step comprising: crossing the two conductors coated with insulation at the position of the slot portion and then integrating the two conductor tapes continuously from both sides with two fixing tapes in the longitudinal direction. The manufacturing method of the description crossing cable.   After forming the slot portion, the two conductors coated with insulation are wound around a drum or a reel while being twisted to cross the two conductors coated with insulation at the position of the slot And a second step of feeding the two conductors after twisting wound around the drum or reel and integrating them by sandwiching them from both sides with two fixing tapes in the longitudinal direction. The manufacturing method of the description crossing cable.
