[Industrial Application Field] The present invention provides a conductor guide passage and a
a conductor device having one or more conductor wires and guided within the conductor guide passage, the conductor device being provided with a lower tower and an upper tower guided thereon, both of which are connected to the conductor ends of the conductor device. The parts transition into each other in a loop, the free end of the lower tower being connected to a fixing device and the free end of the upper tower being connected to a device that is movable back and forth in the longitudinal direction of the conductor. The present invention relates to a conductor guide device.

If necessary, a fixed device can also be connected to the free end of the upper tower and a movable device to the free end of the lower tower. This kind of conductor guide device is
Required when transmitting electrical and/or optical energy and/or gaseous and/or liquid substances between a stationary device and a reciprocating device. It is. In order to carry out this type of transmission, the fixed and mobile devices must generally be connected to each other via a number of conductive wires, which in addition to permitting relative movement between the fixed and mobile devices. They must be guided so that they can work together.

2. Description of the Related Art Conventionally, this problem has been solved by so-called drag chain devices. The device is provided with two or more chain conveyors made of metal or plastic, which are connected to each other by webs at a longitudinal distance. This web keeps two or more chain conveyors at a predetermined distance and holds the individual conductors in position according to the respective shape of the drag chain. This drag chain can also be formed by hose members connected in a chain shape in the longitudinal direction, and
There is a wire running through it.

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 fixed to the fixing device of the drag chain. As a result, the position of the drag chain loop changes in the drag chain longitudinal direction and the individual chain members forming the loop change. Beyond a predetermined drag chain length, the upper chain tower will droop downwardly and the upper chain tower will rest on the lower chain tower.

[0005] Using drug chains is complex;
Therefore, it is an expensive method. The conductors guided by drag chains are subjected to significant mechanical loads. The movement of the drag chain, and in particular the movement of the drag chain loops, creates friction between the conductors and the individual drag chain members, especially in the webs connecting the chain conveyors. For this purpose, the individual conductors guided by the drag chain must all have exactly the same length. This is because otherwise the individual conductors of the drag chain would be subject to excessive shock or stretching loads. The individual conductors are usually connected to electrical connections at both ends of the drag chain. It must be ensured that the load on each conductor is removed separately. If the free supporting length of the drag chain causes the upper chain tower to rest on the chain lower tower, this creates a wear load on the drag chain. In order to prevent this, an intermediate cover in the form of a sliding lamella must be inserted into the guide passage, and the sliding lamina must be sufficiently sturdy to support the upper chain tower. However, it is not possible to extend the sliding plate over the entire travel distance of the movable device. This is because otherwise the drag chain loop would be blocked by the sliding plate even with a slight movement of the movable device. According to known methods, when using a counter-moving drag chain device with two drag chains, this kind of slippage is avoided, except when the distance between the fixed ends of the two counter-moving drag chains is small. Thin plates cannot be used.

[0006]

OBJECTS OF THE INVENTION It is an object of the present invention to provide an alternative to drug chains, which makes it possible to overcome the above-mentioned problems.

[0007]

[Means for Solving the Problems] In order to solve the above problems, in the conductor guide device of the type mentioned at the beginning, the conductors are bundled using a common conductor bundling device, and the conductors are placed outside in the longitudinal direction of the conductor. A structure is adopted in which a sliding device with good sliding characteristics that acts on the conductor is disposed, and the sliding device prevents friction between the upper tower conducting wire portion and the lower tower conducting wire portion even when the length of the conducting wire is long.

[0008]

[Operation] It is also possible to connect the fixed device and the movable device with only one conductor. In that case, it is sufficient if the conductor bundling device is designed to accommodate only one conductor. The conductor bundling device can be formed by conductor clips arranged at a distance from each other in the longitudinal direction of the conductor device and which gather together the conductors, and the sliding device can be arranged on the outside thereof. The device can also be formed by a cable jacket surrounding the conductor.

It is also possible to design the sliding device quite differently. For example, the conductor device is made of a material with good sliding properties that completely surrounds the cable jacket, or it is made of a sliding hose with bending elasticity instead of the cable jacket, for example, a hose made of plastic with good sliding properties is extruded onto the cable jacket. It is also possible to form it by doing. The sliding device may be formed by a sliding belt arranged on the opposing surfaces of the upper and lower tower parts of the cable jacket. Furthermore, it is also possible for the sliding device to be formed by sliding rails arranged on both sides of the conductor clip or cable jacket, the height of which is selected in such a way that it exceeds the thickness of the conductor arrangement surrounding the conductor clip or cable jacket. The sliding device can also be formed by sliding grooves fitted on both longitudinal sides of the conductor clip or cable jacket, the sliding grooves being made of a material with good sliding properties and extending not only to the sides of the conductor clip or cable jacket, but also on the sides. It also covers the upper and lower parts of the area.

The sliding device can be fixed to the conductor clip or the cable jacket in various ways, for example by gluing, welding (for example using ultrasound), or by inserting a locking device arranged on the sliding device into the cable jacket. The fixation may be by extrusion, riveting, nailing, complementary shaped interlocking coupling members on both the cable jacket and the sliding device.

[0011] The sliding device is made of a material with bending elasticity such as steel or a slippery plastic such as polyurethane, polyamide (nylon), polytetrafluoroethylene (also called PTFE) (Teflon: registered trademark). Ru. Preferably the material of the sliding device is harder than the material of the cable jacket. In that case, the sliding device not only mechanically protects the cable jacket from slipping, but also allows the pulling and shearing forces that act during the reciprocating movement of the movable device to be kept away from the conductor device. If the longitudinal end of the sliding device is preferably fastened to a stationary or movable device, it is thereby possible at the same time to relieve the tensile load on the line arrangement.

[0012] If the sliding device is provided with a vertically extending region of a material much harder than the cable jacket material, the sliding device may be provided with a vertically extending region to allow bending of the loop region between the lower and upper towers. Required are longitudinally repeating vertically extending notches, for example wedge gaps, which are open at the top of the lower tower or towards the bottom of the upper tower. If the sliding device is provided with a horizontal region above the lower tower or below the upper tower in addition to the vertical region, the gap continues through this horizontal region.

The sliding device can be provided with a number of sliding elements distributed over the entire length of the conducting line arrangement and projecting on both lateral sides of the conducting line arrangement, which sliding elements are arranged in guide channels arranged on both sides of the conducting line arrangement. You will be guided inside. For this purpose, a pair of mutually overlapping and parallel guide channels is provided on each side of the conductor arrangement, in which guide channels the sliding member is guided. The two guide members of each pair of guide channels are each connected to one another by an archway piece, in which a sliding member of the conductor cable is guided, the sliding member being arranged in the region of the respective loop-forming part of the conductor arrangement. has been done. Since the location of the loop of the conductor arrangement changes with the movement of the movable arrangement, the position of the archway piece must also move accordingly. If the archway piece is fixedly connected to the guideway pair, this is achieved in that the guideway pair and the archway piece can be moved together in the direction of movement of the movable device. If the guide channel is to be kept immovable, the arch channel piece can be moved along the travel path together with the movement of the conductor loop on a sliding block which is movably held in the guide channel. This is possible by fixing the arch passage pieces. In that case, the archway piece is arranged outside the guideway and is movable relative to the guideway. For this purpose, the sliding block is provided with a slope, via which the sliding element on the conductor clip or cable jacket can be moved from the guide channel into the arch channel section and vice versa. In order to enable this movement, in an embodiment of the invention, a sliding member arranged on the conductor clip or on the cable jacket is moved transversely to the direction of movement of the movable device against the force of a compression spring. A quantitative push-in is possible, whereby the height of the slope of the sliding block is compensated.

[0014] The conductor is preferably part of a belt cable. However, they may also be round cables or individual cables. The line arrangement with sliding device according to the invention acts as a self-supporting, self-trailing line arrangement. No other drag chains or drag hoses are required. When using sliding belts, sliding rails, sliding grooves, etc., it is not a problem for the upper tower to rest on the lower tower. This is because the conductor arrangement parts of the upper tower do not come into contact with the conductor arrangement parts of the lower tower, and the areas of the sliding arrangement belonging to the upper and lower towers only slide over each other.

When using a cable without a sliding device according to the invention, the upper tower is placed on the lower tower, so that the jacket area of the upper tower has to slide over the jacket area of the lower tower. Due to the poor sliding properties of the materials normally used for cable jackets, very high friction occurs between the two cable jacket areas. This high friction prevents the upper tower from sliding on the lower tower. In that case, the upper tower is moved above the lower tower by the propulsive action of the movable device, forming another unintended S-shaped loop. This will cause the cable to break. Furthermore, this results in rapid wear of the cable jacket. Additionally, large tensile and shear forces act on the cable to overcome the large cable friction as it moves together with the mobile device.

According to the invention, on the other hand, all the friction is transferred into the sliding device, and the material of the sliding device can be chosen independently of the perspective used for the cable, and with only a low friction in mind. . Large compressive and tensile forces acting on the cable are thereby prevented. Furthermore, compressive and tensile forces of this type are taken up by sliding devices. The line arrangement therefore does not have to be designed with large loads in mind, which makes it very cost-effective.

The sliding device of the present invention can be much cheaper than conventional cable drag chains. In the method according to the invention, sliding plates, as in the known drag chain method, are not required, so that the movement of the conductor arrangement can be carried out even if the conductor arrangements are moved oppositely.
This occurs independently of the length and of the relative position of the fixing device and the movable device.

[0018] Also in the embodiment of the invention with the sliding member guided in the guide channel, the line arrangement is not subjected to any friction between the upper and lower tower regions. It is also possible to attach the sliding device according to the invention directly to a cable or conductor. However, it is also possible to use a channel-like sliding device into which one or more cables or individual conductors can be loosely inserted. Preferably, a conductor path of this type is provided with a bending cutout or a bending gap, which makes it possible to bend the inserted conductor or cable loop.

[0019] It is also possible to combine a number of conductor systems, each with a sliding device, into one unit by connecting the sliding devices of the individual conductor devices to one another. This applies, for example, both if the belt cable is only provided with a partially covering sliding device (for example a lateral sliding groove), and also to a conductor device inserted into the sliding hose. The sliding devices of the individual conductor devices can be connected to each other by welding, crimping, gluing, etc.

The movable equipment of the system, for example a reciprocating robot, is often provided with a conductor connection area, which can be connected when an upper cable tower is placed on a lower cable tower. is located very high above the upper cable tower. If the movable device has a sufficient distance from the respective point of the loop of the conductor device, the conductor device thus forms an S-shaped loop in the area of the conductor device in front of the movable device. In that case, the movement of the movable device places large mechanical loads on the conductor device.

[0021] In a particularly preferred embodiment of the invention, this is prevented by providing the movable device with a space holder which holds the end of the conductor moving with the movable device low. , so that in this region the upper tower is always in contact with the lower tower or is guided directly above it. The region of the fixed end of the conductor device is preferably held in a compensating loop projecting from the sliding device, the ends of which are each clamped and fixed by a conductor clip. The line clip, which is attached to the sliding device end of the compensating loop, is preferably elastically movable relative to the line arrangement in the longitudinal direction of the cable.

Alternatively, for example, the sliding belt 45 or the sliding belts 21, 23 may be replaced by the sliding rail 5 shown in FIG.
It can also be combined with 3 and 55.

FIG. 28 shows an example of a group unit combining two conductor devices according to the invention. Each conductor arrangement is formed by a belt cable 11, whose longitudinal edges project into respective sliding grooves 49, 51. The mutually adjacent sliding grooves 49 and 51 of the two belt cables 11 are placed back to back to each other. The upper side, which has four sliding grooves 49, 51 notches, has a number of transversely extending fixed joint plates 187 arranged in the longitudinal direction of the conductor.
Fixed by This joint plate is connected and fixed to each of the four sliding grooves 49 and 51 by welding, adhesion, or the like.

FIG. 29 shows an enlarged top view of the longitudinal free end of the group unit shown in FIG. 28. Figure 3
0 schematically shows various stages in which the movable device 189 moves away from the loop 17 of the conductor device. The farther the movable device 189 is from the loop 17, the lower the central area of the upper tower 15 hangs towards the lower tower 13 until the upper tower 15 rests on the lower tower 13. Device 18 by which the conductor device is movable
In the area bordering 9, the line arrangement may bend, thereby subjecting the connecting element of the line arrangement and the movable device 189 to undesirable mechanical loads.

FIG. 31 shows the upper tower 1 of the conductor device when the movable device 189 moves towards the loop 17 in the direction of arrow B.
5 schematically illustrates the mechanical loads acting on the area adjacent to the movable device 189 of No. 5; Opposite forces act on the S-shaped region of the upper tower 15 adjacent to the movable device 189, as shown by the downward force arrow K1 and the upward force arrow K2. This may cause this S-shaped area to overturn in case of sudden movements. This can lead to undesirably strong mechanical loads in this area of the upper tower 15.

In the conductor arrangement of the present invention shown in FIGS. 32-35, the problems described in connection with FIGS. 30 and 31 are overcome. Figures 34 and 35 show details within the circles shown in Figures 32 and 33. In the method illustrated schematically in FIG. 32, the movable device 189 is provided with a downwardly projecting space holder 191, at the lower end of which a holder is fixed that holds the free end of the upper tower of the conductor device. The length of the spacer holder 191 is chosen such that the free end of the upper tower is always kept closely on the lower tower 13. A bending movement of the upper tower end connected to the holder and an overturning of the upper tower as described in connection with FIGS. 30 and 31 are thus avoided.

Details of the device, schematically indicated by D34 and D35 in FIGS. 32 and 33, are shown on an enlarged scale in FIGS. 34 and 35. FIG. 34 shows a load relief device in the region of the end of the upper tower 15 combined with a movable device 189. This load relief device is provided with a retaining plate 193 which includes four sliding grooves 49, 51 of the two belt cables 11 combined into one group unit.
It is fixed by a fixing member or a welded part. Since the holding plate 193 is fixed only to the sliding grooves 49, 51 and not to the belt cable 11, the holding plate does not act as a tensile load on the belt cable 11. The ends of the holding plate 193 that protrude beyond the ends of the sliding grooves 49, 51 are fixed to the space holder 191, and the other end of the space holder is fixed to a movable device (not shown in FIG. 34). There is. A cable clip 197 is further fixed to the end of the holding plate 193 that is connected to the space holder 191, so that the sliding groove 49 of the belt cable 11,
The area protruding from 51 is tightened and fixed.

This means that, for example, the cable clip 19
This is done by tightening a tightening plate 199 provided between the bottom of the belt 7 and the belt cable 11 to the belt cable 11 with screws (not shown in FIG. 34). The detailed view of FIG. 35 shows the end of the wire device with a compensation loop 201 and coupled to a fixed device. Also in this embodiment, a tensile load removing plate 203 is fixed to the ends of the sliding grooves 49 and 51 of the two belt cables 11 that are combined into one group unit, and its free end is fixed to the spacer plate 205. has been done. 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 clamped and fixed to the spacer plate 205. Spacer plate 205
An upper cable clip 209 is fixed to the upper end, and the belt cable 11 has sliding grooves 49 and 51 therein.
The area protruding from the can be tightened and fixed. 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 connected to the spacer plate 20, respectively.
Each retaining bolt 211 has a coil spring 215 attached thereto, one end of which is attached to the upper cable clip 209 and the other end attached to the bolt. It is supported by the accommodation hole 213. Opposite ends of the two holding bolts 213 are coupled to a mounting plate 217, which holds the holding bolt 211 immovably. The spacer plate 205 can also be fixed to the conductor guide passage 25.

The compensation loop 201 ensures that the cable at its connection end with the fixing device of the lower tower 13 is protected, for example, when the cable is only inserted into a slide groove or conductor duct but is not fixedly connected to the slide groove or conductor duct. Movement can be compensated for.
