Description

  The present invention relates to a crossover cable suitable for laying in a very narrow place or a place where bending is applied, without receiving a variation in crossing pitch and receiving signals with high accuracy.

  In facilities such as automation factories and three-dimensional warehouses, it is generally performed to transport articles by a moving body such as a carrier. Such a moving body is equipped with a loop antenna, and a signal for confirming the moving position of the moving body is transmitted by the loop antenna. On the other hand, in a moving space of a moving body, a crossing cable along a moving route is usually laid at a position away from the moving body by a predetermined distance as a signal for receiving a signal from a loop antenna. And a movement position etc. of a moving body are confirmed by transmitting / receiving a signal by non-contact transmission between the loop antenna and crossing cable of a moving body.

  As shown in FIG. 3, the conventional crossover cable 101 has two insulated core wires 102, and the two insulation core wires 102 are parallel to each other with a predetermined distance between them and the 2 Crossing portions 105 where the insulated core wires 102 cross each other are alternately arranged in the longitudinal direction. In the conventional crossing cable, in order to make the crossing pitch, which is the distance between the crossing part 105 and the next crossing part 105 constant, the crossing part 105 including the crossing point 104 where the two insulating cores 102 cross each other is used as an adhesive tape or the like. The fixing member 106 is used.

  Further, instead of the fixing member 106, there is also a crossing cable provided with a covering layer that covers the periphery of the two insulated core wires 102 over the entire length of the crossing cable and fixes the crossing portion 105.

  In the above equipment, in order to save space, the cross cable may be routed and laid in a very narrow place or a place where the cross cable is bent. At this time, when the crossing cable 101 in FIG. 3 is pulled through, the fixing member 106 may be peeled off by being caught by something, and the force for fixing the crossing part 105 may be reduced. When the force for fixing the crossing portion 105 is reduced, the zero level of the signal received from the loop antenna of the moving body is disturbed when performing non-contact transmission between the moving body and the crossing cable 101. It becomes impossible to know the movement position accurately. That is, the signal from the moving body cannot be received with high accuracy.

  On the other hand, in a crossover cable provided with a covering layer that fully covers the periphery of the two insulated core wires over the entire length of the crossover cable, a decrease in the force for fixing the crossover can be prevented, but flexibility may be reduced. For this reason, when this crossing cable is bent and installed in a narrow place, workability is poor.

  Accordingly, an object of the present invention is to solve the above-described problems, and to provide a crossover cable that can receive a signal from a moving body with high accuracy and is suitable for installation in a very narrow place or a place where bending is applied.

  In order to achieve the above object, the present invention provides a parallel portion in which two insulating core wires are arranged in parallel at a predetermined distance from each other, and an intersection in which the two insulating core wires are arranged to cross each other. A crossover cable body comprising a crossover cable body alternately having a portion with respect to the longitudinal direction of the insulated core wire, and a storage member provided around the crossover cable body and storing the parallel portion and the crossover portion. The storage member includes a groove for a parallel portion in which two grooves are arranged in parallel at a predetermined distance from each other, and a groove for a cross portion in which the two grooves are arranged to cross each other in the longitudinal direction. A first storage member that is alternately connected to the second storage member, and a second storage member that is disposed opposite the first storage member so as to close the two grooves formed in the first storage member. The parallel part and the intersecting part , Those which are respectively housed inside said parallel portions for grooves and the intersection groove.

  The parallel groove may have the same depth of the two grooves.

  The intersecting portion groove may be deeper than the depth of the parallel portion groove.

  The first storage member may be thinner than the second storage member.

  In the first storage member, the distance between the two grooves in the parallel portion groove is 8 to 25 mm, the length in the longitudinal direction of the parallel portion groove is 100 to 500 mm, and The arrangement pitch in the longitudinal direction of the grooves may be 200 to 1000 mm.

  The first storage member may have a thickness of 25 to 100 μm, and the second storage member may have a thickness of 150 to 500 μm.

  Next, how to assemble two insulated core wires in the crossing cable body will be described.

  As shown in FIG. 2 (a), the crossed cable main body 111 includes a parallel portion 113 in which two insulating core wires 112a and 112b are arranged in parallel with a predetermined distance from each other, and two insulating core wires 112a, Intersections 114 arranged so as to intersect 112b are alternately provided in the longitudinal direction.

  In the crossed cable main body 111 shown in FIG. 2A, the first insulated core wire 112a indicated by hatching is indicated by no hatching at the mth (m is a natural number) crossing portion 114m counted in the longitudinal direction. The second insulation core wire 112b is located in front (front side) of the second insulation core wire 112b, and the second insulation core wire 112b is hidden behind the first insulation core wire 112a (back side). At the (m + 1) th intersection 114m + 1, the second insulating core 112b appears in front, and the first insulating core 112a is hidden away. At the (m + 2) th crossing portion 114m + 2, the first insulating core wire 112a appears to the front, and the second insulating core wire 112b is hidden away.

  As described above, the intersecting cable main body 111 employs an intersecting method in which the first insulating core wires 112a and the second insulating core wires 112b alternately invert the overlapping positions for each one of the intersecting portions 114.

  As shown in FIG. 2 (b), the crossed cable body 121 includes a parallel portion 123 in which two insulating core wires 122a and 122b are arranged in parallel with a predetermined distance from each other, and two insulating core wires 122a, Intersections 124 in which 122b intersect are alternately arranged in the longitudinal direction.

  In the crossed cable main body 121 shown in FIG. 2B, the first insulating core wire 122a indicated by hatching is indicated by no hatching at the mth (m is a natural number) crossing part 124m counted in the longitudinal direction. The second insulating core wire 122b is located behind (the back side) of the first insulating core wire 122a and is located behind (the front side) of the second insulating core wire 122b. Also at the (m + 1) th intersection 124m + 1, the first insulating core wire 122a is positioned in front of the second insulating core wire 122b. At the (m + 2) th crossing portion 124m + 2, the second insulating core wire 122b appears in front, and the first insulating core wire 122a is hidden away.

  In the crossing cable main body 121, the first insulating core wires 122a are positioned on the front side with two continuous crossing portions 124, and are positioned on the back side with the next two continuous crossing portions 124. Two continuous intersections 124 in which the first insulating core wires 122a are located on the front side are defined as a first intersection portion group, and conversely, two consecutive intersections 124 in which the second insulating core wires 122b are located on the front side are defined. If it is set as the 2nd intersection part group, the 1st intersection part group and the 2nd intersection part group will exist alternately in the longitudinal direction. As described above, the intersecting cable body 121 employs an intersecting method in which the first insulating core wires 122a and the second insulating core wires 122b are alternately overlapped at every two intersections 124.

  Hereinafter, the effect of the crossing cable 1 of this invention is demonstrated.

  In the crossing cable 1 of the present invention, the two insulated core wires 2 are housed in the two grooves 5 of the first housing member 8. The first storage member 8 is formed such that the parallel portion grooves 6 and the intersecting portion grooves 7 are alternately connected to the longitudinal direction, and intersects the parallel portion grooves 6 and the intersecting portion grooves 7. The parallel portions 3 and the intersecting portions 4 of the cable body 13 are alternately accommodated and arranged in the longitudinal direction. That is, the insulating core wires 2 can be arranged at a desired crossing pitch only by storing the two insulating core wires 2 in the two grooves 5.

  Therefore, in the crossing cable 1 of the present invention, the crossing pitch Lp of the insulation core wires 2 is determined by the arrangement pitch in the longitudinal direction of the crossing groove 7 and is always kept constant. Even when bending stress is applied to the housing member 9 and bending stress is applied to the insulating core wire 2, the crossing pitch Lp is maintained by the arrangement pitch of the crossing groove 7. At the same time, since the crossing portion 4 of the crossing cable body 13 is held by the first storage member 8 and the second storage member 9, it is possible to prevent the crossing pitch Lp from varying, and the crossing pitch as in the prior art. Will not be disturbed and it will not be possible to know the position of the moving object accurately. That is, even when the crossing cable 1 of the present invention is laid in a very narrow place or a place where bending is applied, the signal from the moving body can be received with high accuracy.

  In the cross cable 1 according to the present invention, the insulation core wire 2 is housed in the groove 5 of the first housing member 8, and the second housing member 9 faces the first housing member 8 so as to close the groove 5. Therefore, it can be visually confirmed whether or not the insulation core wire 2 correctly forms the parallel part 3 and the intersection part 4, and the parallel part 3 and the intersection part 4 are arranged at any position in the longitudinal direction. It is possible to confirm whether this is done by simply observing the appearance of the crossing cable.

  In the cross cable 1 according to the present invention, the two grooves 5 in the parallel portion groove 6 have the same depth, so that the two insulating core wires 2 in the parallel portion 3 are arranged on the same plane. Thereby, the distance from the two insulated core wires 2 to the moving body (not shown) is always kept constant, and signals from the moving body can be received with high accuracy.

  In the crossing cable 1 of the present invention, the depth of the groove 5 in the crossing groove 7 is deeper than the depth of the groove 5 in the paralleling groove 6. In this way, in the crossing groove 7 where the two grooves 5 intersect, the groove 5 is a deep groove, so even if the two insulating core wires 2 are arranged so as to intersect each other, It can be closed by the second storage member 9 having a flat (smooth) surface in the longitudinal direction. Therefore, when the crossing cable 1 of the present invention is laid in a very narrow place or a place where bending is applied, the flat surface of the second storage member 9 is arranged facing the moving body or in the opposite direction, The distance from the insulation core wire 2 to the moving body (not shown) can always be kept constant.

  In the cross cable 1 of the present invention, the first storage member 8 has a thickness of 25 to 100 μm, and the second storage member 9 has a thickness of 150 to 500 μm. If the thickness of the first storage member 8 is less than 25 μm and the thickness of the second storage member 9 is less than 150 μm, the mechanical properties such as the strength to withstand bending and the wearability required for passing through are not satisfactory. May be sufficient. Moreover, there exists a possibility that flexibility may fall that the thickness of the 1st accommodating member 8 exceeds 100 micrometers and the thickness of the 2nd accommodating member 9 exceeds 500 micrometers.

  In the cross cable 1 of the present invention, the distance between the two grooves 5 in the parallel groove 6 of the first storage member 8 is 8 to 25 mm, and the length in the longitudinal direction of the parallel groove 5 is 100 to 500 mm. The arrangement pitch in the longitudinal direction of the grooves 7 for intersections is 200 to 1000 mm. As a result, the distance between the two insulating core wires in the parallel portion 3 is 8 to 25 mm, the length in the longitudinal direction of the parallel portion 3 is 100 to 500 mm, and the arrangement pitch in the longitudinal direction of the intersecting portion 4 (intersecting portion 4). (Distance between intersections) is 200 to 1000 mm. By providing such a configuration, it is possible to effectively block electromagnetic waves (noise) from the outside when the frequency used when performing non-contact transmission is a band of 100 MHz or less. The signal can be received with high accuracy.

  As described above, according to the cross cable 1 of the present invention, the parallel cable 3 and the cross part 4 are provided around the cross cable body 13 and the shape of the cross cable body 13 including the parallel part 3 and the cross part 4 is maintained. Since the storage member 14 is provided, the distance between the two insulation cores 2 does not become non-uniform, and the distance between the two insulation cores 2 is also constant while keeping the crossing pitch Lp constant. Can be held.
