  However, in order to prevent disconnection of the cable for the movable part wiring, the movable part adopts a jacket made of a highly flexible resin such as polyvinyl chloride (PVC) resin, polyurethane (PU) resin, or polyolefin (PO) resin. Since the flexibility of the flat cable for wiring is improved, it is difficult to maintain the straightness of the flat cable for movable part wiring when repeatedly bent in a U-shape, and the flat cable for movable part wiring hangs down. It may come into contact with a structure such as a cable bear.

  Furthermore, in recent years, the adoption of a multi-purpose production system that uses a single precision production line to produce multiple types of products has been promoted. It is necessary to flexibly change the number of air tubes, but since the movable part wiring cable and the air tube are integrated, it is not possible to change the specifications of the movable part wiring cable or the number of air tubes later. Can not.

It is sectional drawing which shows the flat cable for movable part wiring of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the movable part wiring flat cable 100 according to the embodiment of the present invention has a round tube 102 formed so that the movable part wiring cable 101 can be inserted and removed and a corner into which the support member 103 is inserted. The mold tube 104 is arranged in parallel and fixed by a method such as fusion (for example, hot air fusion). The inner diameter of the round tube 102 is formed such that the movable portion wiring cable 101 can be inserted and removed, and a part of the plurality of round tubes 102 is used as an air tube for air driving. The movable part wiring cable 101 may be inserted, the movable part wiring cable 101 may be inserted in all (nothing used as an air tube), or a part may be unused.

  In the following description, the movable portion wiring flat cable 100 that uses a mixture of an air tube and a movable portion wiring cable will be described. The round tube 102 in which the movable part wiring cable 101 is inserted, the round tube 102 in which the movable part wiring cable 101 is not inserted, and the square tube 104 in which the support member 103 is inserted are arranged in any order. The number of movable part wiring cables 101 to be inserted into one round tube 102 is also arbitrary. However, from the viewpoint of balance, it is desirable that the square tubes 104 are arranged on both sides and the center of the movable part wiring cable 101.

  Here, as an air drive source of a device to which the movable portion wiring flat cable 100 is attached by introducing air into or discharging the round tube 102 into which the movable portion wiring cable 101 is not inserted. Can be used.

  The movable part wiring cable 101 may be an electric cable or an optical cable. For example, as shown in FIG. 2, an insulator 107 as an outermost layer is coated around a twisted conductor 106 formed by twisting a plurality of conductors 105. It becomes.

  At this time, the insulator 107 includes an ethylene-tetrafluoroethylene copolymer (ETFE) resin, a tetrafluoroethylene-hexafluoropropylene copolymer (FEP) resin, and a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA). It is desirable to be made of a fluororesin having a low dust generation property such as a resin or polytetrafluoroethylene (PTFE) resin.

  As a result, in the round tube 102 in which the movable portion wiring cable 101 is inserted, it is possible to suppress wear caused by contact between the movable portion wiring cable 101 and the round tube 102 and dust generation due to wear. Become.

  Further, for example, as shown in FIG. 3, the movable part wiring cable 101 has a plurality of binding tapes 111 wound around a stranded wire 109 formed by twisting a plurality of electric wires 108 via an intervening 110, and a plurality of them are wound around the periphery. Alternatively, a shield 112 such as a braided shield or a horizontal shield formed by weaving or winding a wire and a jacket 113 may be covered in order.

  Among these, the jacket 113 is formed on the outer periphery of the inner layer 114 made of a highly flexible resin such as a polyvinyl chloride resin, a polyurethane resin, or a polyolefin resin, and an ethylene-tetrafluoroethylene copolymer resin, An outer layer 115 made of a fluororesin having a low dusting property such as a tetrafluoroethylene-hexafluoropropylene copolymer resin, a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin, or a polytetrafluoroethylene resin; It is desirable that

  Thereby, in the round tube 102 into which the movable part wiring cable 101 is inserted, it is possible to suppress the wear caused by the contact between the movable part wiring cable 101 and the round tube 102 and the dust generation accompanying the wear. Moreover, high flexibility can be imparted to the movable portion wiring cable 101.

  The jacket 113 may not be provided, and a plurality of wires 108 may be simply combined with the bind tape 111 to form the movable part wiring cable 101. However, the outermost layer of the bind tape 111 may be an ethylene-tetrafluoroethylene copolymer resin. It is necessary to form a fluororesin having a low dusting property such as a tetrafluoroethylene-hexafluoropropylene copolymer resin, a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin, or a polytetrafluoroethylene resin.

  Referring again to FIG. 1, the round tube 102 is formed in a cylindrical shape and made of polyurethane resin, and is formed on the outer periphery of the high elasticity tube 116 and contains fluororubber and fluororesin. An outer layer 117 made of an insulating material.

  The square tube 104 is formed in a rectangular tube shape and made of a polyurethane resin, and is formed on the outer periphery of the high elasticity tube 118 and made of an insulating material containing fluororubber and fluororesin. And an outer layer 119.

  The high elastic tubes 116 and 118 play a role of improving the flexibility of the round tube 102 and the square tube 104 to improve the flexibility of the flat cable 100 for wiring the movable part, and the outer layers 117 and 119 are round. While maintaining the flexibility of the mold tube 102 and the square tube 104, the round tube 102 and the square tube 104 play a role of improving the wear and dust generation properties. Generation can be reduced.

  Here, the insulating material preferably contains fluororubber and fluororesin in a mass ratio of 95: 5 to 20:80, and the fluororesin is in a mass ratio of 99.5: 0.5 to 75:25. It is desirable to contain polytetrafluoroethylene and a meltable fluororesin. As an insulating material satisfying these conditions, Daiel (registered trademark) fluoro TPV manufactured by Daikin Industries, Ltd. may be mentioned.

  As a result, the high wear and low dusting properties of fluororesin, and the high flexibility and high elasticity of fluororubber (elasticity is the straightness of the flat cable 100 for wiring the movable part when it is repeatedly subjected to U-bending. It is possible to form the outer layers 117 and 119 having a combination of

  Accordingly, by providing the outer layers 117 and 119, the straightness of the movable portion wiring flat cable 100 when it is repeatedly subjected to U-shaped bending without impairing the flexibility and resistance to repeated U-shaped bending of the movable portion wiring flat cable 100. Can be improved.

  The outer layers 117 and 119 have high oil resistance, high chemical resistance, and high weather resistance possessed by the fluororesin, so that they are in an oil environment, an acidic environment, an alkaline environment, an ultraviolet exposure environment, and the like. The movable part wiring flat cable 100 can also be used.

  The outer layers 117 and 119 preferably have a thickness of 0.2 mm or greater and 0.4 mm or less. The reason is that when the thickness of the outer layers 117 and 119 is less than 0.2 mm, the outer layers 117 and 119 become wrinkles when the flat cable 100 for wiring a movable part repeatedly undergoes U-shaped bending, and finally cracks occur. This is because the high elastic tubes 116 and 118 may be exposed. Further, when the thickness of the outer layers 117 and 119 is more than 0.4 mm, the repulsive force of the movable part wiring flat cable 100 when subjected to repeated U-shaped bending increases, and the cable from the movable part wiring flat cable 100 is increased. This is because the pressure applied to the structure such as the bear is increased, and there is a possibility that the life of the structure such as the cable bear may be shortened.

  Furthermore, it is desirable that the thickness of the outer layers 117 and 119 is 1/5 or more and 1/2 or less of the thickness of the high elasticity tubes 116 and 118. The reason is that when the thickness of the outer layers 117 and 119 is less than 1/5 of the thickness of the highly elastic tubes 116 and 118, the movable portion wiring flat cable 100 and the structure such as the cable bear come into contact with each other. This is because the outer layers 117 and 119 may be shaved and the high elastic tubes 116 and 118 may be exposed within the service period (for example, about 5 years) of the movable part wiring flat cable 100. Further, when the thickness of the outer layers 117 and 119 is more than ½ of the thickness of the highly elastic tubes 116 and 118, the flexibility of the movable portion wiring flat cable 100 is impaired, so that the repeated U-shaped This is because it becomes difficult to maintain the flexibility at the same level as before. Furthermore, since insulating materials such as Daiel (registered trademark) fluoro TPV are more expensive than other resins, the product cost increases remarkably when used in excessive amounts.

  In addition, the round tube 102 and the square tube 104 are formed on the inner periphery of the highly elastic tubes 116 and 118 and are formed of ethylene-tetrafluoroethylene copolymer resin, tetrafluoroethylene-hexafluoropropylene copolymer resin, tetra It is desirable to further include inner layers 120 and 121 made of a fluororesin having low dust generation properties such as fluoroethylene-perfluoroalkyl vinyl ether copolymer resin or polytetrafluoroethylene resin.

  Thereby, in the round tube 102 into which the movable part wiring cable 101 is inserted, it is possible to suppress the wear caused by the contact between the movable part wiring cable 101 and the round tube 102 and the dust generation accompanying the wear. In addition, in the square tube 104 in which the support member 103 is inserted, wear caused by contact between the support member 103 and the square tube 104 and dust generation associated with wear can be suppressed.

  For example, as shown in FIG. 4, the support member 103 includes a chain 122 that bends only in one direction with a constant radius of curvature. The chain 122 has a plurality of portions 123 formed in a trapezoidal shape on the inner peripheral side when repeatedly receiving a U-shaped bend and a portion 124 formed in a rectangular shape on the outer peripheral side when repeatedly receiving a U-shaped bend. The through holes 126 of the chain plate 125 are connected to each other with screws 127. That is, the chain 122 is bent only on the inner peripheral side, and the radius of curvature R when the chain 122 is bent is constant depending on the angle θ formed by the two adjacent chain plates 125.

  The support member 103 is not limited to the chain 122, and a rod-like or plate-like member is inserted only into the terminal portion of the movable portion wiring flat cable 100 to allow the movable portion wiring flat cable 100 to hang slightly. Any mode can be used as long as it has a function to suppress.

  As described above, the movable portion wiring flat cable 100 includes the outer layers 117 and 119 made of an insulating material containing fluororubber and fluororesin on the outer periphery of the highly elastic tubes 116 and 118. It is possible to improve the straightness, wear, and dust generation of the flat cable 100 for moving part wiring when receiving.

  Further, in the movable part wiring flat cable 100, the inner diameter of the round tube 102 is formed such that the movable part wiring cable 101 can be easily inserted and removed, so that the movable part inserted into the round tube 102 is movable. Replacing the part wiring cable 101, pulling out the movable part wiring cable 101 inserted in the round tube 102 and using it as an air tube, or newly moving the round tube 102 used as an air tube A partial wiring cable 101 can be inserted. In this way, the round tube 102 in which the movable part wiring cable 101 is inserted and the round tube 102 in which the movable part wiring cable 101 is not inserted can be arranged in any order and number. The specification of the movable part wiring cable 101 and the number of air tubes can be flexibly changed in accordance with the type of product to be manufactured.

  Therefore, according to the present invention, wear and dust generation associated with wear can be suppressed, and the specifications of the movable part wiring cable 101 and the number of air tubes can be flexibly changed according to the type of product to be manufactured. Is possible.

  Furthermore, since the movable part wiring flat cable 100 includes the square tube 104 into which the support member 103 is inserted, the straight cable is highly rectilinear when it is repeatedly subjected to U-shaped bending, and is wired over a long distance. Even in such a case, it is difficult to sag, so that it is possible to avoid the use of a cable bear and to contribute to downsizing of a surface mounting apparatus or the like.

  The present invention is not limited to the movable part wiring flat cable 100 according to the previous embodiment. For example, as shown in FIG. The square tube 129 may include intermediate layers 130 and 131 made of a semiconductive material containing conductive fine particles and an insulating resin between the highly elastic tubes 116 and 118 and the outer layers 117 and 119. The intermediate layers 130 and 131 serve to prevent the round tube 128 and the square tube 129 from being charged by imparting conductivity to the round tube 128 and the square tube 129.

Here, the semiconductive material preferably contains conductive fine particles in the insulating resin so that the volume resistivity is 0.1 to 10 ³ Ω · cm, and the conductive fine particles are carbon black. In addition, the insulating resin is desirably a vinyl chloride resin, a polyethylene resin, a polypropylene resin, or a polyolefin resin.

  Thereby, even if static electricity occurs in the movable part wiring flat cable 200, the static electricity can be converted into thermal energy, and the static electricity can be effectively removed. In addition, since the vinyl chloride resin has high flexibility, it is possible to prevent the flexibility of the round tube 128 and the square tube 129 from being lowered by using the vinyl chloride resin as the insulating resin.

  The intermediate layers 130 and 131 preferably have a thickness of 0.1 mm or more and 0.5 mm or less. The reason is that if the thickness of the intermediate layers 130 and 131 is less than 0.1 mm, the effect of removing static electricity is poor, and if the thickness of the intermediate layers 130 and 131 is more than 0.5 mm, the overall outer diameter is small. This is because it becomes thicker and it becomes easier to sag due to its own weight.

  Furthermore, it is desirable that the thickness of the intermediate layers 130 and 131 is 1/10 or more and 1/2 or less of the thickness of the highly elastic tubes 116 and 118. The reason is that if the thickness of the intermediate layers 130 and 131 is less than 1/10 of the thickness of the high elastic tubes 116 and 118, the effect of removing static electricity generated from the high elastic tubes becomes poor, and the intermediate layers 130 and 131 are insufficient. This is because if the thickness is more than ½ of the thickness of the high elastic tubes 116 and 118, the elasticity of the high elastic tubes is impaired, and the entire flat cable is heavy and easily drops.

  As described above, by providing the intermediate layers 130 and 131 made of the semiconductive material containing the conductive fine particles and the insulating resin between the highly elastic tubes 116 and 118 and the outer layers 117 and 119, the movable part wiring flat Static electricity generated when the cable 200 repeatedly undergoes U-bending can be effectively removed.

  Next, specific examples of the present invention will be described.

  Six round tubes are manufactured by forming an outer layer by coating Daiel (registered trademark) fluoro TPV on the outer periphery of a highly elastic tube made of polyurethane resin, which is formed in a cylindrical shape, and in a rectangular tube shape Two square tubes are produced by forming an outer layer by coating Daiel (registered trademark) Fluoro TPV on the outer periphery of a highly elastic tube formed of polyurethane resin.

On top of that, when the movable part wiring flat cable is not held by the cable bearer and is directly wired to the precision manufacturing line, the movable part wiring flat cable hangs even if the U-bend movement distance is 1.5 m repeatedly. There was no. In addition, wear is repeated even when U-shaped bending is repeated 10 million times or more under the conditions of a bending radius of 38.4 mm (six times the outer diameter of the round tube), a repetition rate of 30 times / minute, and a moving distance of 1.5 m. No dust generation due to or wear.

  On the other hand, a semiconductive material (volume resistivity 1 Ω · cm), which is formed into a cylindrical shape and contains carbon black and vinyl chloride resin on the outer periphery of a highly elastic tube made of polyurethane resin, Daiel (registered trademark) fluoro TPV, In order to form six round tubes by forming an intermediate layer and an outer layer, carbon black and chloride are formed on the outer periphery of a highly elastic tube made of polyurethane resin. Two rectangular tubes are formed by coating a semiconductive material (volume resistivity 1 Ω · cm) containing vinyl resin and Daiel (registered trademark) fluoro TPV in order to form an intermediate layer and an outer layer. The two square tubes were arranged on both sides and fused in parallel.

  At this time, in the round tube, the inner diameter of the highly elastic tube is set to 4 mm, the outer diameter is set to 6 mm, the thickness of the intermediate layer is set to 0.2 mm, and the thickness of the outer layer is set to 0.2 mm. The diameter was 6.8 mm. In addition, in the square tube, the outer dimension of the high elastic tube is a square of 6 mm × 6 mm, the wall thickness is 1 mm, the thickness of the outer layer is 0.2 mm, and finally the outer dimension is 6.8 mm × 6. The cross-sectional square was 8 mm.

  Furthermore, three of the six round tubes are used as air tubes, and movable part wiring cables such as power lines and signal wires are inserted into the remaining round tubes, and the two square tubes Each chain was inserted to produce a flat cable for wiring the movable part. On top of that, when the movable part wiring flat cable is not held by the cable bearer and is directly wired to the precision manufacturing line, the movable part wiring flat cable hangs even if the U-bend movement distance is 1.5 m repeatedly. There was no. In addition, even when the U-shaped bending is repeated 10 million times or more under the conditions of a bending radius of 40.8 mm (six times the outer diameter of the round tube), a repetition rate of 30 times / minute, and a moving distance of 1.5 m, Dust generation due to wear did not occur. Moreover, the static electricity generated by the round tube and the square tube during repeated U-shaped bending could be absorbed and removed by the intermediate layer.

  As described above, the effect of the present invention was demonstrated.
