Abstract

(57) [Abstract] [Purpose] This project makes it easy to recognize the input side and the output side of the same cable among multiple single-core cables 1'constituting a multi-core cable that is used by being inserted into a pipe. The purpose is to improve efficiency. [Structure] The wire bundle 2 is spirally wound around the insulated wire bundle 1 and bound, the wire bundle 1 is exposed between the spiral pitch p of the wire bundle 2, and the identification mark 3 is provided on each insulated wire 1 '. A control cable that is provided at substantially equal intervals t.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This proposal relates to a control cable for automatic equipment and the like arranged in the factory.

[0002]

[Prior art]

 Mainly for control line laying work (protection pipe wiring) for automation in factories, etc., it is from several meters to several hundred meters with a single type (eg VSF) insulated wire, and the number of cables is from several to several hundred. That is, (1) Standardized multi-core cables are not convenient and convenient to use, and are expensive. (2) Since the wires are of a single type and there is no mark on each line, miswiring is likely to occur. If miswiring occurs, it is necessary to check at both ends for one wire, especially if the wiring length is several hundred meters. Takes a long time. (3) When the identification mark is displayed on each line before wiring, each line can be wrapped with a display tape, so the cable diameter of the display part is large and it is difficult to pass through the pipe and is not suitable for practical use. (4) With the above-mentioned multi-core cable, the required number is taken out on site and cut into the same length. However, if the number is too large, it will take time and the mark will be erased by the above cutting.

[0003]

[Problems to be solved by the device]

 The purpose of this plan is to use a required number of single-core cables (single-core insulated wires) as a bundle of control cables to obtain inexpensive and convenient cables.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present proposal is to wrap a wire bundle around an insulated wire bundle in a spiral shape to expose the wire bundle between the spiral pitches of the wire bundle, and to provide a discrimination mark on each insulated wire. Control cable provided at equal intervals Insulated electric wire is a single-core cable Control cable according to the above-mentioned invention. Control cable according to the above-mentioned first or second invention, wherein the plurality of filaments are bundled in spiral directions opposite to each other. Consists of a control cable.

[0005]

[Action]

 In this plan, the insulated wire bundle 1 is inserted into the pipe, the wire bundle 1 is exposed from the pipe at the destination, and the identification mark 3 marked on the insulated wire 1'and the insulated wire 1 exposed from the other end of the pipe Check that they are the same insulated wire 1 by matching the discrimination mark 3 written on the '.

Even when the destinations are different, since the discrimination marks 3 are provided at substantially equal intervals t, the mark 3 can be recognized even if the electric wire 1 ′ is cut midway.

[0007]

【Example】

 By pulling a plurality of single-core insulated electric wires 1 '(single-core cables) from the plurality of take-up reels 4 and passing them through the printing device 5, the above-mentioned electric wires 1'are provided with a mark 3 for distinguishing numbers, symbols and the like. Printing is performed at the interval t by stamp 5'or thermal transfer or the like.

The electric wire 1 ′ thus formed is passed through the center through holes 7 and 7 ′ of the rotating discs 6 and 6 ′ by pulling to pass the bundle 1 and is provided on the side faces of the discs 6 and 6 ′. The filaments 2 and 2 such as strings or strings (vinyl) drawn from the idle reels 8 and 8'are spirally wound around the outer periphery of the bundle 1, and the first disc 6 is moved in the direction of arrow a ( By rotating the second circular plate 6'in the positive direction) and rotating the second circular plate 6'in the direction of the arrow b (reverse direction), the bundle 1 is exposed between the pitches p of the filaments 2, 2. As-is cable can be formed.

Reference numeral 9 in the drawing denotes an external gear of the discs 6 and 6 ′, 10 is a driving small gear that meshes with the external gear 9, 11 is a reduction drive motor, and 12 in FIG. 4 is a conventional mark vinyl. Tube.

[0010]

[Effect of device]

 Since the present plan is configured as described above, the insulated wire bundle 1 can be bound (fixed) in the exposed state, the outer diameter can be made relatively small, and it is easy to pass through the pipes and is easy to use. The discrimination mark 3 of each covered electric wire 1'of the electric wire bundle 1 cut regardless of the distance can be recognized, and there is an effect that the miswiring of the conducting wire is small and the construction can be simplified.
