Description

The invention generally relates to an energy guiding chain for the active guidance of conduits, such as cables, hoses or the like, between two connection points, of which at least one is mobile.

Such energy chain are known. In typical construction has a power transmission chain, each with two opposite side flaps. The side flaps are, usually in overlapping areas, pivotally connected to each other pivotally about a pivot axis transverse to the longitudinal direction of the energy guiding chain and form two lashing strands of side flaps articulated or linked together in the longitudinal direction of the energy guiding chain. Between the tabs an interior space for the lines is provided. On at least some chain links at least one transverse web is provided, which connects the tab strands with each other.

It is also known e.g. in applications with long travel distances and / or high travel speeds, energy guiding chains in guidance systems such as e.g. Guide troughs or the like. To lead. In applications where the one strand, e.g. the upper strand, opposite the other strand, e.g. the lower strand, not to rest or slide off the leadership of the upper strand is not possible without special devices, since the deflection arc must be moved, i. the members have to extend and retract towards the leadership.

For example, special folding systems have been proposed which carry the upper strand, cf. EP 2 419 981 B1 , This is a safe guide, especially against a deviation of the upper run vertically upwards but not possible.

For smaller building applications was in EP 1 869 744 B1 proposed another solution in which a portion of the side flaps is bent in an extended position to the outside. The laterally projecting portion serves as a support member to serve on a support surface of a guide rail. So the upper run can be held. For applications with high forces, such as high load weights and or high accelerations, this design is only partially suitable due to the impairment of the side flaps.

A band-like cable guide device with sliding transversely to the longitudinal axis, adjustable against a spring sliding elements was in EP 0490 022 A2 proposed (see. 25 - 27 there). This is not an actual energy chain in the sense of a link chain, so that, among other things, the advantage of any line assembly, easy line replacement in case of maintenance and punctual repair damage is not given here.

It is therefore a first object of the invention to propose a further development of generic energy supply chains, with which a cooperation with guide systems, in particular with a linear or circular guide for at least one of the dreams, is simplified or simpler guidance systems can be used. In addition, a reliable guidance of the energy guiding chain in both directions of the energy guiding chains perpendicular to the longitudinal direction, even in very fast moving applications, is to be made possible.

This object is achieved by an energy guide chain according to claim 1, a guide arrangement according to claim 13 and independently by a side flap according to claim 14.

According to one aspect of the invention, it is proposed according to claim 1 that two mutually hinged side flaps have at least one associated transverse to the longitudinal direction of the energy guiding chain, e.g. perpendicular or oblique thereto, slidably mounted crosspiece and a conversion gear, which converts a relative pivoting of both side plates in a translational displacement of the crosspiece. This allows the crosspiece retract and extend, depending on the relative pivotal position, solely due to the intended pivotal movement of the chain links or side plates. The crosspiece can thus in particular when pivoting in a direction about the pivot axis, e.g. towards the extended position, extend laterally and when pivoting in the other direction about the pivot axis, e.g. in the Umlenklage in the deflection bend, retract laterally. In particular, the crosspiece may be displaceable between a retracted position and a position projecting laterally outwardly beyond the side flaps, e.g. to cooperate with a guide assembly with guide rails or the like.

This includes u.a. Complex guiding devices with moving parts are not required. In addition, the inherent pivotal movement of the tabs is utilized to achieve the translational displacement of the crosspiece between a projecting operative position and a retracted rest position.

The crosspiece is preferably a separate component from the side flaps, which may be made in one or more parts. The shape of the crosspiece is in itself arbitrary and application dependent. The cross piece can eg as a pin, bolt or the like. Be rotationally symmetric and optionally have other components such as rollers.

In a mechanically simple embodiment, the crosspiece is slidably mounted substantially parallel to the pivot axis, e.g. coaxial to the pivot axis of cooperating with the crosspiece chain or side flaps.

In one embodiment, at least one, preferably both side flaps, respectively, has a receptacle for the crosspiece. wherein the crosspiece is arranged and guided therein preferably coaxially to the pivot axis. The crosspiece may be slidably disposed and guided in the receptacle or receptacles coaxially with the pivot axis, e.g. in the manner of a linear sliding guide.

As a conversion gear different rotation / translation conversion gear come into consideration. Thus, e.g. a kind of wedge drive may be provided on the side flaps, which causes only the displacement to the outside, whereas the resetting inwardly by a run-on slope on the crosspiece and their interaction with the guide, e.g. an inclined surface is effected on a guide rail,

In a preferred embodiment, the conversion gear is designed as a movement thread, screw drive or as a helical gear. In this case, e.g. the crosspiece be the threaded member and have at least one side tab a matching mating thread or vice versa. The crosspiece can be held against rotation on the other side flap.

In a development with a movement thread or helical gear is preferably provided that the crosspiece, in the manner of a tube, on the outside has at least two Gewindevorsprünge and a recording of a first of the two side plates, so to speak as a counter tube of the helical gear, inside has at least two corresponding thread grooves. Thus, the thread projections can engage in the thread grooves to implement a relative rotation of the side plates in the translational displacement of the crosspiece. The thread pitch is application dependent u.a. from the desired displacement path and the predetermined for forming the Umlenkbogens pivoting angle between the side plates or chain links. In a further development of this embodiment, it is provided that the cross piece has two locking pins on the outside and the receptacle of the other or second of the two side flaps has on the inside two guide grooves aligned axially with respect to the pivot axis. As a result, the locking pins can be guided axially displaceably in the guide grooves to hold the cross-piece slidably but rotationally fixed to this second side flap.

In particular, in the case of such a movement thread or helical gear for actuating the crosspiece, the first side flap may have a radially arranged first stop face for the crosspiece, e.g. its locking pin, and the second side flap has a radially disposed second stop surface for the crosspiece, e.g. the locking pin and / or the thread projections, so that the first and second stop surface each limit the translational displacement of the cross piece. If the abutment surface interact with the locking pins and / or thread projections, these preferably have end faces perpendicular to the pivot axis.

In the last-mentioned variant, the abutment surfaces of the side flaps can advantageously limit the pivoting angle of the side flaps in both directions about the pivot axis with the crosspiece, in particular with the arresting pins and / or the thread projections, so that no further angle stops have to be provided. This simplifies the design of the side flaps.

The invention can be realized with different types of tabs. A compact design with movement thread or helical gear can be achieved if the tabs have alternately arranged first and second side flaps, namely inner flaps and outer flaps. In contrast, the inner straps have overlapping regions located proximal to the inner space and the outer straps have outer or distal overlapping regions, wherein the side straps are articulated on the basis of the overlapping regions. In this embodiment, it is advantageous if the inner plates and outer plates have cylindrical receptacles for the crosspiece, wherein preferably the inner plate in the receptacle for the crosspiece thread grooves, which cooperate with thread projections on the crosspiece in the manner of a movement thread. Accordingly, the outer link in the receptacle for the crosspiece preferably has axial guide grooves, which cooperate with locking pins on the crosspiece to store these translationally displaceable and rotationally fixed to the outer link.

In a further development, in particular of the last-mentioned construction, it is provided that the inner straps and / or the outer straps, preferably both, each have a separate holding part with end-side guide grooves into which a guide projection of the respectively adjacent side tab engages in the mounted state. This allows the Inner plates and outer plates are held stably to each other laterally to the longitudinal direction and the assembly, in particular with the crosspiece, is simplified. The holding part can be attached in any attachment technique to the inner flap and / or the outer flap, for example by screw or locking connection, etc.

The displaceable crosspiece can be designed as a transverse bolt, in particular when arranged coaxially to the pivot axis. For weight reduction and material savings, it is advantageous if the crosspiece is designed as a hollow pin. In order to provide a large peripheral surface, in particular for functional elements of the conversion gear, the hollow bolt preferably has an inner diameter of at least one third (33%) of the tab height of the side flaps in the plane perpendicular to the chain longitudinal direction. Also, in another approximate cylindrical solid body, a corresponding outer diameter may be provided to provide sufficient area, e.g. for a screw drive to provide.

The side flaps may be made of plastic, e.g. As injection molded parts, are produced inexpensively. The crosspiece can also be made of plastic. If appropriate, the crosspiece is also produced as an injection-molded part, preferably made of another plastic, in particular an artificial material with tribological properties, which produces a tribologically favorable material pairing with the side flaps. Crosspieces and / or side plates made of metal are also possible.

Depending on the application, it may be sufficient for a guide of at least one of the two chain strands if at least a few chain links each have a displaceable crosspiece on both sides, e.g. every nth chain link. An aligned opposite arrangement of cross pieces on the same chain link avoids u.U. occurring torsional forces during the process, in particular in a two-sided leadership.

In order to increase the number of identical parts and / or to ensure reliable trouble-free guidance over long travel distances, it is advantageous if all side straps of both straps have at least one crosspiece.

In particular, in this design, it is possible, but not mandatory, when the side plates are connected by means of sliding cross pieces in the manner of chain pins at the same time hinged together. The cross pieces can also be freed from the transmission of force in the link straps if the side straps have a suitable alternative articulation connection.

According to another aspect, the invention also relates to a guide arrangement having an energy guiding chain which connects the energy guiding chain to a first strand, e.g. a lower strand, and a second strand, e.g. an upper strand forms, which are interconnected by a deflection arc. The guide arrangement has two opposite guide rails for at least one of the strands with which this upper strand is conveyed on a given travel path, e.g. linear, is guided. According to the invention, an energy guiding chain is equipped with adjustable, in particular displaceable cross pieces, which can be displaced by the pivoting movement of the chain links and which engage in the guide rails in an extended position in order to guide the energy guiding chain in these guide rails. This allows a reliable, escape-proof management of the energy chain and u.a. the use of particularly simple designed guide rails, in particular a guide arrangement which manages without moving parts.

According to a further independent aspect, the invention also relates to a side flap as such, which has a transversely, in particular vertically or obliquely, slidably mounted to the main plane of the side flap crosspiece, wherein the side flap and the cross piece are designed to form a conversion gear which pivotal movement of the side flap opposite a translated with this side flap in translational displacement of the crosspiece. For this, e.g. a two- or 2n-common movement thread is used, in particular with at least or exactly two thread grooves on the side flap or on the crosspiece and on the other hand at least two cooperating thread grooves on the crosspiece or on the side flap.

1 - 7 show purely exemplarily a preferred embodiment of an energy guiding chain 1 , The energy chain 1 is made of individual chain links 2 assembled, each chain link 2 here in the longitudinal direction L alternately either two outer plates 3 or two inner straps 4 having. The outer plates 3 and inner plates 4 alternate sequentially in the longitudinal direction L the energy chain 1 , The outer plates 3 and inner straps 4 are hinged together and form on both sides of the energy chain 1 one strap section 8A each; 8B. 2A - 2C illustrate only one strap 8A , the opposite (not shown) is identical and arranged mirrored. At least some chain links 2 are the link plates, here, for example, only inner plates 4 , through two crossbars 5 stable connected. As a result, the tabs are 8A ; 8B kept parallel. Between the link plates 3 . 4 and the crossbars 5 forms the energy chain 1 an interior for not shown here in detail lines, such as cables for power and / or signal supply and / or hoses for supplying media to a mobile consumer (not shown) based on the energy chain 1 is supplied.

1 shows four identical guide rails 6 , eg aluminum profiles, with an inside guide groove 7 by means of which the upper strand and / or lower strand of the energy chain 1 along the predetermined, here linear travel safely guided. Other guideways, such as circular paths are within the scope of the invention. For guidance in the guide grooves 7 are on both opposite tabs 8A . 8B According to the invention provided special transversely displaceably mounted crosspieces, which in the example shown here as a cross pin 10 , more precisely as hollow pins, are executed. Every cross bolt 10 Depending on the relative pivotal position of two linked chain links 3 . 4 extended laterally outward (see. 7A - 7B ) or back in the side flaps 3 . 4 retracted (cf. 6A - 6B ). The invention particular design of the link plates 3 . 4 and the crosspiece or transverse pin 10 will be described in more detail below.

When relative pivoting a pair of outer flap 3 and inner flap 4 from the extended position ( 7A ) in the mutually pivoted position ( 7B ) becomes the cross bolt 10 retracted and when pivoting in the opposite direction is the cross bolt 10 extended. Only in the side extended position ( 7B ) engages the cross bolt 10 in the guide grooves 7 the guide rail 6 a, ie when pivoting the cross bolt 10 is retracted out of engagement to allow undisturbed movement of the Umlenkbogens.

For the realization of this integrated in the chain links actuator each forms an assembly of an outer flap 3 , an inner flap 4 and a cross bolt 10 in the example shown a kind of movement thread or helical gear for the implementation of the rotational movement of the link plates 3 . 4 in the translational movement of the transverse pin 10 , In the example shown, a movement thread is provided, but this is not mandatory.

The cross bolt 10 For this purpose, it is designed with a substantially cylindrical base body (here as a hollow bolt) with two radially opposite projections formed on an end portion of the thread projections 11 , The thread protrusions 11 are designed as helical ridges and project radially outward from the cylindrical body. The thread protrusions 11 act with two threaded grooves designed as counter threads 41 together and have corresponding lateral thread surfaces 11A the with corresponding mating surfaces 41A the thread grooves 41 interact, here as a two-speed movement thread. The threaded surfaces 11A and counter surfaces 41A run helically around the pivot axis S or symmetry axis A of the transverse bolt. The thread pitch is structurally selectable but should not be self-locking. The thread grooves 41 are radially opposite to a substantially cylindrical receptacle 42 inside the inner plates 4 intended ( 4 shows only one of the two opposite thread grooves 41 ).

Every cross bolt 10 also has two radially opposite locking pins 12 , which project outside of the cylinder shell of the body. The locking pins 12 are with guide surfaces 14 Mistake. The guide surfaces 14 run parallel to each other and to the radial center plane through the axis of symmetry A of the transverse bolt 10 , The locking pins 12 act with parallel to the pivot axis S extending guide grooves on both cylindrical receptacles 31 together. By the guide 32 and the locking pins 12 are the cross pieces 10 transversely displaceable, but on the outer flap 3 rotatably or not rotatably supported relative to this. The design of the locking pin 12 and guide grooves 32 also gives one to the pivot axis S coaxial translation of the transverse pin 10 in front. Compared to the end-side thread projections 11 are the locking pins 12 in the longitudinal direction of the crosspiece 10 arranged closer to the longitudinal center.

The axisymmetric guide grooves 32 in the outer straps 3 are executed blind hole-like and each have a stop surface 33 perpendicular to the pivot axis S on. At this stop surface 33 hit end stop surfaces 33 the locking pin 12 to the maximum displacement transverse to the longitudinal direction L to limit the energy supply chain. In the opposite direction is the translation of the transverse bolts 10 by a radially arranged circular disc-shaped stop surface 43 at the edge of the picture 42 the outer plates 3 limited. The stop surfaces 33 , 43 can be used together with the front stop surfaces 13 In addition, the swivel angle limit for the relative pivoting of outer flap 3 and inner flap 4 cause each other, as together with the corresponding threaded surfaces 11A and counter surfaces 41A a kind of wedging of the transverse bolt 10 the pivoting movement of both tabs 3 . 4 limited relative to each other in both pivoting directions.

The cross bolt 10 Can also be used as a chain pin for pivotal connection of the tabs 3 . 4 serve. In the arrangement shown, the transverse pin is used 10 but not primarily as a chain pin and is with sufficient radial clearance for a smooth transverse displacement in the recordings 31 . 42 arranged.

For articulation have the inner plates 3 each in both overlapping areas 34A . 34B coaxial to the pivot axis S a circular cylindrical bearing projection 35 , The bearing projection 35, the crosspiece 10 in mounting arrangement and forms an axially projecting circular disc-shaped bearing pin, outside of each recording 31 , The outer flap 4 has each in both overlapping areas 44A . 44B coaxial to the pivot axis S a matching circular cylindrical bearing recess 45 , in which the corresponding bearing projection 35 engages for pivotal mounting. The storage recess 45 surrounds as a recessed gradation in the inner flap 4 Coaxially the recording 42 ,

For fastening the side flap 3 . 4 each other is how best 2 B can be seen on the inner straps 4 and on the outer straps 3 each center a separate holding part 50 attached. The holding part has frontal, circular arc running around the pivot axis guide grooves 52 , in which a here circular arc continuous guide projection 54A . 54B the respective adjacent side flap 3.4 state engages and forms a kind of rear handle, so that the side flap 3 . 4 transverse to the longitudinal direction L firmly secured to each other.

The cross bolt 10 is here designed to save weight as a hollow bolt and here has an inner diameter D on which is about 40-45% of the tab height. Accordingly, the substantially cylindrical transverse pin has 10 a large outer surface for the molded thread projections 11 and locking pins 12 , and the helical gearbox 11 . 41 receives favorable forces or moments ratios.

In the example shown, the inner plates 4 thread-bearing and the outer plates 3 keep the cross bolts rotation proof. A reverse arrangement is possible. The invention is not based on screw drives and not only on energy chains with alternating inner and outer plates, such as from the patent EP 0 803 032 B1 known, limited. The proposed combination of crosspiece or cross bolt with a suitable conversion gear, such as a wedge drive, the relative pivoting of both side plates in a translational displacement of the cross piece converts to the crosspiece and extend can also in side plates with cranked construction, such as in EP 0 819 226 B1 proposed to be used.
