Description

Arrangement of a line guidance system with a reversing drive

Technical Field

The invention relates to a line guiding system comprising a line guiding unit, in particular for guiding cables and hoses. Such a line guiding unit may also be referred to as an energy guiding chain.

Background

Different designs of line guiding units are known from the prior art. With these designs, a line, such as a cable or a hose, can be guided between two components that can be moved relative to each other. In particular, damage to the line due to movement of the components should be prevented by the line guide unit.

The conventional pipeline guiding unit is a so-called energy guiding chain. The energy guiding chain is formed by links which are connected to each other in an articulated manner and can be pivoted relative to each other.

The arrangement and course of movement of the line guiding unit depends on many factors. Different settings are known from TSUBAKI KABELLSCHLEPP GmbH company 2018, catalog "DER GROSSE KABELSCHLEPP Energieketten aus Vollkunststoff Kunststoff mit Aluminium-Stegen Stahl/Edelstahl", pages 74-89. In particular in the field of reciprocating warehouse technology, so-called "zig-zag" arrangements are preferred, since a very space-saving arrangement can be achieved thereby. When space conditions are sufficient, a vertically suspended or upright line guiding unit may be used.

Storage systems which operate according to the chain bucket elevator (Paternoster) principle are known in the storage art. Here, the warehouse platform is fixed on two opposing endless chains. The warehouse platform here passes through two steering points, an upper and a lower steering point, so that the platform first performs a vertical upward movement up to the upper steering point. In the region of the upper turning point, the platform moves transversely to the upward movement direction, so that a downward-oriented vertical movement is then carried out up to the lower turning point. At the lower turning point the platform is moved transversely to the vertical so that it reaches its starting position again.

Disclosure of Invention

On the basis of this, the object of the invention is to provide a line guiding system which enables the possibility of coupling components which utilize the line guiding unit for carrying out a reciprocating movement, a lateral movement and a downward movement and vice versa in an imaginary vertical plane.

According to the invention, the object is achieved by a line guidance system having the features of claim 1. Advantageous refinements and designs of the invention are the subject matter of the dependent claims.

The line guiding system according to the invention has a line guiding unit arranged in a suspended manner. The utility line guide unit has a first end that is arranged in a fixed manner and a second end that is arranged in a fixed manner. The two fixedly arranged ends of the line guide unit are preferably arranged at the same height relative to the same foundation.

A steering unit is disposed between the fixedly positioned first end and the fixedly positioned first end. Here, an arrangement is preferred in which the steering unit is arranged not higher than the two fixed ends.

Furthermore, the line guide system according to the invention has a reversing-type drive which cooperates with the line guide unit.

The line guide unit is arranged suspended such that it forms a first U-shaped section between the first fixed end and the steering unit and a second U-shaped section between the steering unit and the second fixed end.

The line guiding unit further comprises a transfer unit, by means of which the line arranged in the line guiding unit can be guided out of the line guiding unit to a component, in particular a warehouse platform of a warehouse system.

This embodiment of the line guide unit requires that the line guide unit can be bent both counter-clockwise and clockwise when the line guide unit is in a stretched state. Such a line guiding unit also refers to a line guiding unit that is formed such that it can achieve a radius of curvature and a reverse radius of curvature.

The advantage of the line guide system according to the invention is that the line guide unit is subjected to a tensile load independently of the direction of rotation of the drive device operating in reverse. This is particularly important because a defined movement of the line guide unit is thereby possible, the chain links of which can form both a radius of curvature and a reverse radius of curvature.

The line guide unit is preferably formed by articulated links. Each link comprises two side plates, which are preferably connected to each other by two transverse webs, so that each link defines a substantially rectangular cross section in which a pipeline can be guided.

In order to achieve a defined displacement path, a design is particularly preferred, wherein the line guide unit has a driver which interacts with a correspondingly embodied steering unit.

The driver preferably has a cross section which is configured to be circular. The driver may be a pin-shaped element, which is arranged in particular centrally on a side part of the chain link.

The chain links of the line guide unit are preferably made of plastic. The driver is preferably also made of plastic. A special possibility exists for the driver and the side part to be formed integrally.

In order to increase the stability of the movement of the line guide unit, the steering unit is preferably formed by rollers having spaced apart flanges in the axial direction, between which the line guide unit is guided. The flange has a groove, preferably formed radially inwards, into which the driver engages.

In order to achieve a particularly compact design of the line guidance system, it is proposed according to a further advantageous embodiment to connect the steering unit to a drive.

The line guided in the line guiding unit can be led out of the line guiding unit by a transfer unit and be connected to, for example, a storage platform. There is also the possibility that the pipeline directing unit has multiple care-of units.

In which a pipeline having a reserved length is preferably guided. Thereby, the difference in the moving path can be compensated. In particular, it is preferred that the pipeline has a reserved length on the care-of unit.

The line guidance system according to the invention is particularly suitable for warehouse systems which operate in reverse according to the chain bucket elevator principle. In this case, "reversing" means that the chain bucket elevator principle does not work in a cyclic manner, but only through the upper turning point.

Detailed Description

A first embodiment of a line guidance system 1 can be seen in fig. 1. The line guiding system 1 comprises a line guiding unit 2. The line guiding unit 2 has a first fixed end 3a and a second fixed end 3b. A steering unit 4 is provided between the first fixed end 3a and the second fixed end 3b.

The line guiding unit 2 is arranged such that it is arranged suspended. The suspended arrangement of the line guiding units 2 forms a first U-shaped section 6a. In the embodiment shown, the first U-shaped section 6a extends from the first fixed end 3a all the way to the steering unit 4. Furthermore, a second U-shaped section 6b is provided, which is formed between the steering unit 4 and the second fastening end 3 b. The line guiding unit 2 has a care-of unit 7. The care-of unit 7 will be discussed in more detail below. The steering unit 4 is configured to be rotatable about an axis 5. For this purpose, the steering unit 4 can be connected to a drive device, which is not shown in fig. 1. The drive is configured such that it operates in a reversing manner. This means that the steering unit 4 can be rotated clockwise or counter-clockwise, which is indicated by arrow C in fig. 1.

As can be seen from fig. 1, both the first U-shaped section 6a and the second U-shaped section 6b have a curved section a. The line guiding unit 2 partly surrounds the steering unit 4. If the curved section of the line guiding unit 2 denoted a is defined such that this curved region a has a certain radius of curvature, the opposite curved region B on the steering unit 4 is a region with an opposite radius of curvature. Visually, the U-shaped sections 6a, 6b are concavely curved, while the curved sections of the line guiding unit on the steering unit are convexly curved.

In a preferred embodiment of the line guidance system, the distance of the shaft 5 from the fixed ends 3a, 3b is equidistant. The line guiding unit 2 is preferably wrapped around the steering unit 4 over an angle of 180 °. In combination with the equal distance between the first fixed end 3a and the shaft 5 and between the shaft 5 and the second fixed end 3b with respect to the horizontal, a deflection angle of 180 ° achieves the advantage that the branches of the first U-shaped section 6a and the branches of the second U-shaped section 6b in the line guiding unit 2 extend parallel to each other, respectively.

A first embodiment of a link 10 of a wire guide unit 2 is shown in fig. 2. The line guiding unit formed by articulated interconnected links is also called an energy guiding chain or simply an energy chain.

The chain link 10 is formed by two side parts 11a, 11b which are spaced apart from each other and arranged in parallel. The side parts 11a, 11b are connected to each other by transverse webs 12a, 12b, so that the chain link 10 defines a substantially rectangular space in which a line, not shown, can be arranged.

On one end region of each side part 11a, 11b, a pin 13 is provided, which points outwards with respect to the chain link. On the opposite regions of the side parts 11a or 11b, holes 14 are provided, which are configured such that they are suitable and designed to receive the journals 13 of adjacent links. The side parts 11a, 11b have stops by means of which the pivot angle of adjacent links can be defined.

As can be seen in the perspective view in fig. 2, a driver 16a is provided on the outer side 15 a. The driver 16a is preferably arranged centrally on the side part 11 a. The driver 16a has a circular cross section. Corresponding entrainers are also provided on the outer side 15b of the side part 11 b.

The or each driver may be connected as a separate component to the respective side part. The side parts 11a, 11b and the drivers 16a, 16b are preferably integrally formed. This can be achieved, for example, by making the side parts and the driver from a plastic material.

Returning to fig. 1, the steering unit 4 has a recess 17 which is configured to correspond to the shape of the entrainer 16a, 16 b.

In fig. 3, a second embodiment of a chain link 10 of the line guide unit 2 is shown. The basic structure of the link according to fig. 3 corresponds to the structure of the link according to fig. 2. In this respect, reference is made to the description of the chain link according to fig. 2, and only differences from the embodiment of the chain link according to fig. 2 are discussed.

The chain link according to fig. 3 has a driver 16a, 16b which is formed in several parts, the respective side part 11a, 11b having an outwardly oriented pin 18. Rollers 19a or 19b are provided on the pin 18. In order to fix the roller 19a or 19b, threaded bores are provided in the pin 18, into which screws 20 are screwed. A retaining disk 21 is arranged between the screw head of the screw 20 and the support 19a, by means of which disk the axial fixing of the roller 19a is achieved. A corresponding arrangement is also possible in conjunction with the roller 19b.

The design of the driver with rotatable rollers has the advantage that friction between the driver and the recess in the steering unit can be reduced.

Fig. 4 shows schematically the steering unit 4 in a side view. In the embodiment shown in fig. 4, the steering unit 4 comprises rollers 22. The roller 22 has flanges 23a, 23b formed at a distance from each other. Each flange 23a, 23b has a radially inwardly directed recess 17, into which the respective driver 16a or 16b engages when a section of the line guiding unit 2 is partially wrapped around the steering unit 4. Flanges 23a, 23b have a larger outer radius than roller 22 so that link 10 is guided between flanges 23a, 23b.

The steering unit 4 is connected to a drive device 24. The drive device 24 may be connected to the steering unit 4 indirectly or directly. The drive means 24 may be, for example, a motor drive. A corresponding transmission 25 may also be provided between the drive 24 and the steering unit 4.

It is also possible that the drive unit is formed, for example, by a drive belt which is coupled to a drive of the device which cooperates with the line guidance system and functions.

The steering unit 4 is rotated by a reversing drive 24. If the steering unit 4 is rotated in a clockwise direction as shown in fig. 1, the first U-shaped section 6a of the line guiding unit becomes shorter, as the links of the line guiding unit 2 with their followers 16a, 16b reach into the respective recesses 17a, 17 b. At the same time, the second U-shaped section 6b of the line guiding unit 2 is correspondingly lengthened.

If the direction of rotation of the steering unit 4 is reversed, i.e. the steering unit 4 rotates anticlockwise, the second U-shaped section 6b becomes shorter and the first U-shaped section 6a becomes longer. By the rotation of the steering unit 4, the transfer unit 7 is also moved in the vertical direction. The transfer unit 7 is designed such that it can be moved past the steering unit 4, so that the transfer unit 7 can be transferred from the first U-shaped section 6a into the second U-shaped section 6b depending on the number of revolutions of the steering unit 4.

The pipeline may be led out of the pipeline guiding unit by a care-of unit 7. The pipeline may then be connected to a corresponding interface on the device or apparatus.

Fig. 5 schematically shows a second embodiment of the line guiding system. In this line guiding system, as shown in fig. 5, the line guiding system also has a line guiding unit 2 with a first fixed end 3a and a second fixed end 3 b. Between the first fixed end 3a and the second fixed end 3b, the steering unit 4 is formed by rollers comprising axially spaced apart flanges between which the line guiding unit 2 is guided. The line guiding unit 2 is arranged suspended.

As can be seen from fig. 5, the diameter of the steering unit 4 is small compared to the distance between the two fixed ends 3a and 3 b. In order to achieve that the branch lines of the line guidance units of the U-shaped sections 6a and 6b extend substantially parallel to each other, i.e. substantially vertically, guide channels 25a, 25b are provided on both sides of the steering unit 4, which guide channels are shown enlarged in fig. 6. The guide channels 25a, 25b are preferably U-shaped. In the case of a corresponding dimensioning of the steering unit 4 and the presence of other geometric factors, such as, for example, the spacing of the fastening points, the radius of curvature of the energy guiding chain and the radius of reverse curvature, it is not necessary to provide the guiding channels 25a, 25b. Nevertheless, it may be reasonable to provide the guiding element and/or the protective element at different positions, for example for windbreak.

Fig. 5 shows a line guide system 1 in combination with a warehouse system operating according to the chain bucket elevator principle. Warehouse systems operating according to the chain bucket elevator principle have long been known. Thus, for example, DE 1 938 640a discloses a device for parking a motor vehicle that operates according to the chain bucket elevator principle.

In fig. 5 a chain 26 is shown, which is arranged vertically and guided by a lower sprocket 27 and an upper sprocket 28. A second chain, not shown, can be provided parallel to this arrangement, which is also guided by the respective upper and lower sprockets. Between and connected to the two chains there is a platform 29, which is connected to the two chains, for example according to the basket principle, so that the platform 29 always remains horizontally oriented. The bucket elevator principle may include a plurality of platforms 29.

In fig. 5, it is schematically shown that the care-of unit 7 is connected to said platform 29, so that the pipeline can be guided from the pipeline guiding unit to the platform 29.

The drive of the steering unit 4 is coupled to the drive of the gears 27, 28, so that the transfer unit 7 moves substantially synchronously with the platform 29. In order to compensate for differences in the path of movement between the platform 29 and the gear 28 as one side and the care-of unit 7 and the steering unit 4 as the other side, the line leading from the care-of unit 7 to the platform 29 may have a reserve length compensating for the road section.

Unlike conventional warehousing systems based on the chain bucket elevator principle, the platform does not move past the lower turning point at the lower sprocket 27.

If the sprocket 28 is driven in the clockwise direction corresponding to arrow C, the platform 29 moves and the steering unit 4 coupled with the movement of the platform 29 moves simultaneously, whereby the transfer unit also moves. If the movement is proceeding vertically upwards, the steering unit 4, the platform 29 and the transfer unit 7 pass through a steering point, at which the lifting movement is transferred to the lowering movement. Due to the construction of the chain bucket elevator and the line guiding system, the line guiding unit performs a combination of movements in the vertical direction and movements occurring in the vertical and horizontal directions.

By means of the cooperation of the suspended line guide unit and the drive device with the line guide unit via the steering unit, only tensile forces are exerted on the line guide unit. This configuration has the great advantage that no additional guide elements, for example for the U-shaped section of the line guide unit, are necessarily required. In the case of the use of the subject matter of the invention, preferably together with a warehouse system operating according to the chain bucket elevator principle, it is also possible to supply the or each platform with power and signals safely and reliably, since the pipeline is not only protected but also guided with certainty in a complex course of movement by the energy guiding chain.
