Generally, a coiled tube or hose is used to transfer fluid between moving members or between a fixed member and a moving member.
例えば、ロボツト等のように複雑な動作を行う
機器においては、流体の授受の系統が複数である
場合が多く、そのため多心コイルチユーブが必要
とされる。 For example, in devices that perform complex operations such as robots, there are often multiple fluid transfer systems, and therefore multi-core coil tubes are required.

が必要となり整造コストの点で問題がある。 Conventionally, as a coil tube of this type, for example, Japanese Utility Model Application Publication No. 59-77680 discloses a multi-core coil tube which is made by twisting a plurality of tubes together, covering them with a protective layer, and then forming a coil. ing. Although such a coil tube has excellent restorability, it requires work steps such as twisting and coating with a protective layer, which poses a problem in terms of preparation cost.

た。 Further, Japanese Utility Model Application Publication No. 58-181085 discloses, as another assembly structure, a multicore coil tube in which a plurality of plastic tubes are bonded side by side by adhesive or heat fusion and formed into a coil. These coil tubes do not require a step of coating with a protective layer, so they can be manufactured at a lower cost than the former, but on the other hand, they have the following drawbacks. That is, the joining of plastic tubes by adhesive is
It is difficult to apply adhesive only to the bonded area, and the applied adhesive may protrude outside the bonded area, resulting in a poor appearance.Additionally, it takes time to bond, so improvements can be made in terms of manufacturing costs. There is still room for. In addition, since bonding by heat fusion is performed by heating the plastic tube above its melting temperature, if thermoplastic resin such as fluororesin or polyamide resin is used as the tube material, the temperature at which fusion can be achieved Because the softening temperatures of the tubes are close to each other, it is difficult to firmly fuse the tubes without deforming them (hereinafter, plastic materials with such properties are referred to as hard-to-bond resins). Bonding using urethane resins has been limited to those using some resins such as urethane resins.

This idea was devised in view of the drawbacks of the prior art described above, and is a multi-core coil tube made by integrating multiple plastic tubes and processing them into a coil.Even if the plastic tube is difficult to heat-seal, it can be easily and reliably bonded. can be combined with
The purpose of the present invention is to provide a multicore coil tube that does not separate even after repeated use.

This invention was made in order to solve the problems of the prior art described above, and for this purpose, according to this invention, a plurality of pieces of hard-to-fuse resin are formed into a coil shape and are arranged in a non-bonded state. a tube consisting of a tube, and a heat-shrinkable gripper provided at at least two locations on the coiled portions of the plurality of tubes and integrally surrounding the outer circumferences of the plurality of adjacent tubes in a non-bonded state. A multi-core coil tube is constructed.

加工後に収縮させることができる。 In this configuration, the gripping body that holds the outer periphery of all the tubes is a plastic tube whose inner diameter has been expanded and has the property of returning to its original diameter by heating (so-called heat shrink tube). The coiled part is loosely inserted into at least two places of the coiled part, and is heated and shrunk.
If more than one tube is used, the tubes are provided at regular or arbitrary intervals in the longitudinal direction, and these heat-shrinkable tubes can be shrunk before or after coiling.

合も難しいことから特に好都合である。 In addition, in the multi-core coil tube according to this invention, the tube material to be integrated is a resin that is difficult to heat-seal, such as polyamide resin or fluororesin. Among these, it is particularly advantageous when fluororesin tubes are concentrated to form a multi-core coil tube because it is difficult to bond them together by adhesive.

According to this invention, as described above, tubes made of a plurality of hard-to-fusible resins formed into a coil shape and placed side by side in a non-bonded state are bound together by a shrinkable member such as a heat-shrinkable tube. Therefore, when tubes that are difficult to heat-seal can be made into multiple cores, they can be easily and reliably integrated. In addition, according to this invention, if a plurality of tubes are tied together at least at two places in the coiled part, and similar binding parts are provided at both ends of the multi-core coil tube, the connecting parts of the individual tubes can be tied together. Since the uneven stress load is reduced, separation will not occur even after repeated use, and the durability of the multi-core coil tube will be greatly improved.

The figure is a side view of a multi-core coil tube 1 according to this invention. This multi-core coil tube 1 is made by closely winding tubes 2a and 2b made of two hard-to-bond resins such as fluororesin into a coil shape.
The intermediate portion is heated and formed into a coil shape, and heat shrinkable tubes 3 serving as grippers are loosely inserted into mutually opposing positions of each coil layer 2 consisting of tubes 2a and 2b. A heat-shrinkable tube is provided at each terminal end for bundling the ends, and these heat-shrinkable tubes 3 and 4 are integrated by heating and shrinking.

Since the multi-core coil tube 1 is configured to be held one by one by the gripping body 3, the two tubes 2a and 2b can be held together very easily, and they will not separate due to repeated expansion and contraction. Longer life of the multi-core coil tube is achieved.

条件によつては必ずしも設ける必要はない。 In addition, in the above example, the case where the heat-shrinkable tube serving as the gripping body was loosely inserted after coil processing and then heat-shrinked was explained, but it is of course also possible to loosely insert and heat-shrink the tube before coil processing. . Further, in the embodiment, a case has been described in which a gripping body is also provided at the terminal end of the coiled portion, but it is not necessarily necessary to provide it depending on the usage conditions.

As explained above, according to this invention, there are tubes made of a plurality of hard-to-bond resins that are formed into a coil shape and arranged side by side in a non-bonded state, and at least two portions of the coiled portions of these tubes. By configuring a multi-core coil tube with a gripper made of heat-shrinked plastic tubes that integrally wraps the outer periphery of a plurality of adjacent tubes, tubes that are difficult to heat-seal can be used. When the tube is integrally coiled, the work is not only simplified, but the tube does not separate even when used repeatedly, which has a great practical effect.
