[0001]

BACKGROUND OF THE INVENTION This invention comprises a wire guide passage, and a belt cable guided by the <br/> wire guide path, is guided thereon and lower tower to the belt cable An upper tower , both of which form a loop at the wire end of the belt cable and transition to each other, wherein the free end of the lower tower is connected to a fixing device and the free end of the upper tower is The present invention relates to a wire guide device connected to a device capable of reciprocating in the longitudinal direction of a belt cable .

[0002] If necessary, a fixed device can be connected to the free end of the upper tower and a movable device can be connected to the free end of the lower tower. This type of wire guide device is
What is needed when trying to transmit (transmit electric and / or optical energy and / or transmit gaseous and / or liquid substances) between a stationary device and a reciprocating device It is. In order to perform this type of transmission, the fixed device and the movable device must generally be connected to each other via a number of conductors, and the conductors allow the relative movement of the fixed device and the movable device in addition to the relative movement. You must be guided so that they can work together.

[0003]

2. Description of the Related Art Conventionally, this problem has been solved by a so-called drag chain device. The apparatus is provided with two or many chain conveyors made of metal or plastic, which are connected to one another by webs at a longitudinal distance. This web keeps two or many chain conveyors at a given distance and holds individual conductors in positions corresponding to the respective shape of the drag chain. The drag chain can also be formed by a hose member joined in a chain shape in the longitudinal direction, and a conducting wire is passed through the hose member.

When the reciprocating device moves, the end of the drag chain fixed to the movable device is moved in the longitudinal direction of the drag chain with respect to the end of the drag chain fixed to the fixing device. As a result, the position of the drag chain loop is changed to the drag chain longitudinal direction, each chain member forming a loop changes. If the length of the drag chain is exceeded, the upper tower of the chain hangs down and the upper tower of the chain rests on the lower tower of the chain.

[0005] The use of drag chains is complicated,
Therefore, it is an expensive method. The wires guided by the drag chains are subject to significant mechanical loads. The movement of the drag chain and, in particular, the position of the drag chain loop, causes friction between the conductors and the individual drag chain members, especially on the web connecting the chain conveyor. For this purpose, the individual conductors guided by the drag chain must all be of exactly the same length. Otherwise, the individual conductors of the drag chain will be subjected to excessive shock or stretching loads. Individual conductors are usually connected to electrical connections at both ends of the drag chain. The load on the individual conductors must be removed separately. If the free support length of the drag chain causes the upper tower of the chain to rest on the lower tower of the chain, this creates a wear load on the drag chain. In order to prevent this, an intermediate cover in the form of a sliding slat must be inserted into the guide passage, and the sliding slat must be strong enough to support the upper tower of the chain. However, the sliding sheet cannot be extended over the entire moving distance of the movable device. Otherwise, the drag chain loop would be blocked by the sliding slats with only a small movement of the mover. When using a drag chain device having two drag chains that move in opposition to each other in a known manner, this type of sliding is used, except when the distance between the fixed ends of the two drag chains that move in opposition is small. Sheets cannot be used.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an alternative to a drag chain which can overcome the above-mentioned problems.

[0007]

A configuration is adopted in which a sliding device is arranged to prevent friction between the upper tower conductor and the lower tower conductor even when the length of the belt cable is long. Also, this slip dress

Cable.

[0008]

[Action] The guide wire bundling device, are spaced longitudinally a distance from each other of the line assembly, formed by wire clips to combine conductor can be arranged a sliding device on the outside. The device can also be formed by a cable jacket surrounding the conductor.

It is also possible for the sliding device to be formed completely differently. For example, the conductor device may be made of a material having good sliding properties and completely surround the cable jacket, or formed of a sliding hose having bending elasticity in place of the cable jacket, for example, extruding a hose made of plastic having good sliding properties onto the cable jacket. It is also possible to form by doing. The sliding device may be formed by a sliding belt arranged on the surface of the cable jacket where the upper and lower tower portions oppose each other. It is also possible for the sliding device to be formed by sliding rails arranged on both sides of the conductor clip or conductor jacket, the height of which is selected to exceed the thickness of the conductor device surrounding the conductor clip or cable jacket. The sliding device can also be formed by sliding grooves mounted on both longitudinal sides of the conductor clip or cable jacket, the sliding grooves being made of a material with good sliding properties, not only on the sides of the conductor clip or cable jacket, but also on the sides. It also covers the area above and below the area.

The sliding device can be secured to the conductor clip or the cable jacket in various ways, for example by gluing, welding (for example by means of ultrasound), and a locking device arranged on the sliding device in the cable jacket. Extruded, riveted, nailed, secured by complementary mating mating members on both the cable jacket and the sliding device.

The sliding device is made of a material having bending elasticity such as steel or a slippery plastic such as polyurethane, polyamide (nylon), polytetrafluoroethylene (also referred to as PTFE) (Teflon (registered trademark)). You. Preferably, the material of the sliding device is harder than the material of the cable jacket. In this case, the sliding device not only mechanically protects the cable jacket from slipping, but can also keep the pulling and shearing forces acting when the movable device reciprocates away from the conductor. If the longitudinal end of the sliding device is preferably fixed to a fixed or movable device, this also makes it possible to eliminate the tensile load on the conductor device at the same time.

If the sliding device, which is made of a material much harder than the cable jacket material, is provided with a vertically extending area, the bending of the loop region between the lower tower and the upper tower is possible in order to allow the bending of the sliding device. Notches, e.g. wedge gaps, which are repeated in the longitudinal direction and need to be open vertically in the upper part of the lower tower or in the lower part of the upper tower, are required. If, in addition to the vertical area, the sliding device is provided with a horizontal area above the lower tower or below the upper tower, the gap extends through this horizontal area.

The sliding device can be provided with a number of sliding members distributed over the entire length of the conductor device and projecting on both sides of the conductor device, the sliding members being guide passages arranged on both sides of the conductor device. Will be guided within. For this purpose, a pair of guide passages is provided on both sides of the conductor device, which overlap and extend in parallel with each other, and the sliding members are guided in the guide passages. The two guide members of each pair of guide passages are respectively connected to one another by an arch passage piece, in which the sliding members of the conductor cable are guided, the sliding members being arranged in the region of the respective loop-forming parts of the conductor arrangement. Have been. Since the location of the loop of the conductor device changes with the movement of the movable device, the position of the archway piece must also move accordingly. If the archway piece is fixedly connected to the guideway pair, this is achieved by the fact that the guideway pair and the archway piece can move together in the direction of movement of the movable device. If the guide passage is to be held immovably, moving the arch passage piece together with the movement of the conductor loop along the path of movement will not be possible on a sliding block movably held in the guide passage. This is made possible by fixing the archway pieces. In that case, the arch passage piece is arranged outside the guide passage so as to be movable with respect to the guide passage. For this purpose, the sliding block is provided with a slope, and the sliding member provided on the conductor clip or cable jacket is moved from the guide passage into the archway piece via the slope and vice versa. To enable this movement, in an embodiment of the invention, the sliding members arranged on the conductor clip or on the cable jacket are each positioned transversely to the direction of movement of the movable device against the force of the compression spring. It can be pushed in a fixed amount, whereby the height of the slope of the sliding block is compensated.

The conductor is preferably part of a belt cable. However, it may also be a round cable or an individual cable. The wire system with the sliding device of the present invention acts as a self-supporting, self-trailing wire system. No other drag chains or drag hoses are required.
When using sliding belts, sliding rails, sliding grooves, etc., there is no problem with the upper tower resting on the lower tower. This is because the conductor section of the upper tower does not come into contact with the conductor section of the lower tower, and the regions belonging to the upper and lower towers of the sliding device only slide over one another.

If a cable without a sliding device according to the invention is used, the upper tower is mounted on the lower tower, whereby the jacket area of the upper tower has to slide over the jacket area of the lower tower. In particular, the poor sliding properties of the materials normally used for cable jackets result in very high friction between the two cable jacket regions. This high friction prevents sliding movement of the upper tower on the lower tower. In that case, the upper tower is moved above the lower tower by forming another unintended S-shaped loop by the propulsive action of the movable device. The cable is thereby broken. In addition, it leads to rapid wear of the cable jacket. In addition, high tensile and shear forces act on the cable to overcome the high cable friction as the cable moves with the mover.

According to the invention, on the other hand, the friction is entirely transferred into the sliding device, and the material of the sliding device can be selected only with low friction, irrespective of the viewpoint used for the cable. . This prevents large compressive and tensile forces acting on the cable. In addition, such compressive and tensile forces are received by the sliding device. Therefore, the conductor device does not have to be designed with a large load in mind, which makes it very cost-effective.

The sliding device of the present invention can be much less expensive than conventional cable drag chains.
In the method of the present invention, since the sliding thin plate is not required as in the case of the known drag chain method, the movement of the wire device is performed even when the wire device is moved in opposition.
It is performed undisturbed irrespective of the length and irrespective of the relative position of the fixed device and the movable device.

In an embodiment of the present invention having a sliding member guided in the guide passage, the conductor arrangement does not receive any friction between the upper tower area and the lower tower area.
It is also possible to mount the sliding device according to the invention directly on a cable or a conductor. However, it is also possible to loosely insert one or more cables or individual conductors therein by means of a sliding device in the form of a passage. Preferably, a bend notch or bend gap is formed in such a wire passage, so that the inserted wire or cable loop can be bent.

By connecting the sliding devices of the individual conductors to one another, it is also possible to combine a number of conductors, each having a sliding device, into one unit. This applies, for example, to the case where the belt cable is provided with only a sliding device (for example, a lateral sliding groove) that covers a part thereof, and also to a wire device inserted into a sliding hose. The connection of the sliding devices of the individual conductors to one another can be effected by welding, swaging, gluing or the like.

The mobile devices of the system, for example reciprocating robots, are often provided with a wire connection area, which is used when the upper cable tower is mounted on the lower cable tower. Is provided at a very high position above the upper cable tower. Thus, if the movable device is at a sufficient distance from each location of the loop of the conductor, the conductor forms an S-shaped loop in the area in front of the movable device of the conductor. In that case, when the movable device moves, a large mechanical load is applied to the conductor device.

This is prevented, in a particularly preferred embodiment of the invention, by providing a space holder on the movable device, which space holder holds the moving end of the wire together with the movable device low. In this area, the upper tower always contacts the lower tower or is guided directly above the lower tower. The area of the fixed end of the conductor device is preferably held in a compensation loop protruding from the sliding device, the ends of which are each clamped by a conductor clip.
In this case, the conductor clip attached to the end of the compensating loop on the slide device side is preferably resiliently movable in the cable longitudinal direction with respect to the conductor device.

In the area contacting 9, the wire arrangement can bend, which can place an undesired mechanical load on the connecting elements of the wire arrangement and the movable device 189.

FIG. 31 shows that when the movable device 189 moves to the loop 17 in the direction of arrow B, the upper tower 1
5 schematically illustrates a mechanical load acting on an area adjacent to the movable device 189 of FIG. As indicated by the lower force arrow K1 and the upper force arrow K2, opposing forces act on the S-shaped area of the upper tower 15 adjacent to the movable device 189. This may cause the S-shaped region to be turned over when moving rapidly. This can cause undesirable high mechanical loads in this area of the upper tower 15.

In the conductor arrangement of the present invention shown in FIGS. 32 to 35, the problems described in connection with FIGS. 30 and 31 have been overcome. Figures 34 and 35 show details within the circles shown in Figures 32 and 33.

This means that, for example, the cable clip 19
This is performed by tightening a fastening plate 199 provided between the bottom of the belt cable 11 and the belt cable 11 with screws (not shown in FIG. 34). The detailed view of FIG. 35 shows the end of the lead wire device having a compensation loop 201 and coupled to a stationary device. In the present embodiment, the tensile load removing plate 203 is fixed to the ends of the sliding grooves 49 and 51 of the two belt cables 11 combined in one group unit, and the free end is fixed to the spacer plate 205. Have been. A lower conductor clip 207 is provided at the lower end of the spacer plate, by means of which the free ends of the two belt cables 11 can be fastened and fixed to the spacer plate 205. Spacer plate 20
The upper cable clip 209 is fixed to the upper end of the belt cable 5, and the sliding grooves 49, 5
The area emerging from 1 can be clamped. Holding bolts 211 are provided at both lateral ends of the upper cable clip 209, respectively. The ends of the bolts 211 on the spacer plate side are the spacer plates 2 respectively.
05 is slidably held in a bolt receiving hole, and a coil spring 215 is attached to each of the holding bolts 211. One end of the coil spring is connected to an upper cable clip 209, and the other end is connected to a bolt. It is supported by the accommodation hole 213. Opposite ends of the two holding bolts 213 are coupled to the mounting plate 217, and the holding plate 211 holds the holding bolt 211 immovably. The spacer plate 205 can be fixed to the wire guide passage 25.

By means of the compensation loop 201, for example, if the cable is only inserted into the slideway or the lead-through but is not fixedly connected to the slideway or the lead-through, the cable at the connection end of the lower tower 13 with the fixing device is connected. Motion can be compensated.
