Der Erfindung liegt die Aufgabe zugrunde, Möglichkeiten der Energiezuführung, insbesondere Stromzuführung, zu linear beweglichen Komponenten gegenüber dem genannten Stand der Technik weiter zu entwickelten, wobei ein kompakter, montage- und reinigungsfreundlicher Aufbau angestrebt wird und der Raum um den Verfahrbereich der linear gelagerten Komponenten weitestmöglich freigehalten werden soll. The invention is based on the object of further developing possibilities for supplying energy, in particular power, to linearly movable components compared to the aforementioned prior art, whereby a compact, assembly- and cleaning-friendly design is sought and the space around the travel range of the linearly mounted components is to be kept as free as possible.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Energiezuführungsvorrichtung mit den Merkmalen des Anspruchs 1. Die Energiezuführungsvorrichtung ist insbesondere als Teil eines Linearsystems nach Anspruch 8 nutzbar. This object is achieved according to the invention by an energy supply device with the features of claim 1. The energy supply device can be used in particular as part of a linear system according to claim 8.
Die Energiezuführungsvorrichtung ist allgemein zum Anschluss an einen linear verschiebbaren Energieabnehmer vorgesehen und umfasst The energy supply device is generally intended for connection to a linearly displaceable energy consumer and comprises
- ein zur ortsfesten Installation vorgesehenes Anschlusselement, - a connection element intended for fixed installation,
- einen am Anschlusselement schwenkbar gelagerten, in einer horizontalen Ebene bewegbaren Dreharm, welcher ein Teleskoprohr umfasst,- a rotating arm which is pivotably mounted on the connecting element and can be moved in a horizontal plane and which comprises a telescopic tube,
- einen mit dem Teleskoprohr gelenkig verbundenen, zum Anschluss an den Energieabnehmer vorgesehenen Vertikalabschnitt, - a vertical section connected to the telescopic tube in an articulated manner and intended for connection to the energy collector,
- eine im Dreharm angeordnete, an den Vertikalabschnitt angeschlossene Energiekette, wobei zum Längenausgleich bei Verschiebungen des Energieabnehmers ein gebogener Abschnitt der Energiekette vorgesehen ist, welcher in mindestens einer halben Windung um die Schwenkachse des Dreharms gelegt ist. Bei dem Energieabnehmer kann es sich insbesondere um eine auf Schienen verfahrbare Plattform oder um eine auf einer solchen Plattform montierte Maschine handeln. In allen Fällen kann sich das ortsfest installierte Anschlusselement über und/oder neben dem verschiebbaren Energieabnehmer befinden. Die Verschiebung des Energieabnehmers kann mit Leistung, die über die Energiezuführungsvorrichtung bereitgestellt wird, oder auf beliebige sonstige Weise erfolgen. - an energy chain arranged in the rotating arm and connected to the vertical section, wherein a curved section of the energy chain is provided to compensate for length in the event of displacement of the energy collector, which is laid in at least half a turn around the pivot axis of the rotating arm. The energy collector can in particular be a platform that can be moved on rails or a machine mounted on such a platform. In all cases, the fixed connection element can be located above and/or next to the movable energy collector. The energy collector can be moved using power provided by the energy supply device or in any other way.
Insbesondere ist das Anschlusselement in der Mitte des Verschiebebereichs des Energieabnehmers - bei seitlicher Ansicht der verschiebbaren, dem Energieabnehmer zuzurechnenden Komponenten - montiert. Der Dreharm, welcher am Anschlusselement gelagert ist, ist um eine ortsfeste Schwenkachse verschwenkbar, typischerweise um nicht mehr als 180°, insbesondere um maximal 150°, womit ein einziger Freiheitsgrad der Schwenkbewegung gegeben ist. In particular, the connection element is mounted in the middle of the displacement range of the energy collector - when viewed from the side of the movable components attributable to the energy collector. The rotary arm, which is mounted on the connection element, can be pivoted about a fixed pivot axis, typically by no more than 180°, in particular by a maximum of 150°, which provides a single degree of freedom of the pivoting movement.
Die Energiekette ist derart in das Teleskoprohr des Dreharms eingebaut, dass eine feste örtliche Relation zumindest zwischen dem vordersten, an den Vertikalabschnitt angeschlossenen Abschnitt des Teleskoprohrs und der Energiekette gegeben ist. Die Bezeichnung „Teleskoprohr“ wird unabhängig von der Querschnittsgestaltung dieses Rohres verwendet. Auch offene, gitterartige, längenverstellbare Elemente, die die Energiekette tragen, werden unter den Begriff „Teleskoprohr“ subsumiert. The energy chain is installed in the telescopic tube of the rotating arm in such a way that there is a fixed local relationship at least between the frontmost section of the telescopic tube connected to the vertical section and the energy chain. The term “telescopic tube” is used regardless of the cross-sectional design of this tube. Open, grid-like, length-adjustable elements that carry the energy chain are also included under the term “telescopic tube”.
Längenänderungen des Teleskoprohrs werden durch die Energiekette mit vollzogen, indem der zumindest teilweise um die Schwenkachse des Dreharms gewundene Abschnitt der Energiekette je nach Einstellung des Teleskoprohrs einen engeren oder weiteren Bogen beschreibt. Dies hat unter anderem den Vorteil, dass eine Massenkonzentration in der Nähe der Schwenkachse vorliegt. Der Dreharm selbst kann dagegen sehr schlank und reinigungsfreundlich ausgeführt werden. Optional weist der Dreharm seitliche Abdeckbleche auf, die einfach entfernbar sind, um beispielsweise einen Zugang zu den Kabeln der Energieführungskette zu ermöglichen. In vorteilhafter Ausgestaltung ist der gebogene Abschnitt der Energiekette in einem starr mit dem Dreharm verbundenen Gehäuse angeordnet. Auch dieses Gehäuse kann glatte, chemisch resistente Flächen aufweisen, die sehr leicht zu reinigen sind. Changes in length of the telescopic tube are carried out by the energy chain in that the section of the energy chain that is at least partially wound around the pivot axis of the rotating arm describes a narrower or wider arc depending on the setting of the telescopic tube. This has, among other things, the advantage that there is a mass concentration near the pivot axis. The rotating arm itself, on the other hand, can be designed to be very slim and easy to clean. Optionally, the rotating arm has side cover plates that can be easily removed, for example to allow access to the cables of the energy chain. In an advantageous embodiment, the curved section of the energy chain is arranged in a housing rigidly connected to the rotating arm. This housing can also have smooth, chemically resistant surfaces that are very easy to clean.
Bei dem Anschlusselement kann es sich insbesondere um eine zur Deckenmontage vorgesehene Anschlussplatte handeln, wobei das schwenkbare Gehäuse eine flache, zur Anschlussplatte parallele Form aufweist. The connection element can in particular be a connection plate intended for ceiling mounting, with the pivotable housing having a flat shape that is parallel to the connection plate.
Auch Ausführungsformen mit einem zur Wandmontage vorgesehenen Anschlusselement, insbesondere in Form einer Anschlussplatte, sind möglich. Unabhängig davon, wo das Anschlusselement befestigt ist, kann das zusammen mit dem Dreharm schwenkbare Gehäuse zum Beispiel mittels eines als Axial-Schrägkugellager ausgebildeten Schwenklagers an der Anschlussplatte gelagert sein. Embodiments with a connection element intended for wall mounting, in particular in the form of a connection plate, are also possible. Regardless of where the connection element is attached, the housing, which can be pivoted together with the rotating arm, can be mounted on the connection plate, for example by means of a pivot bearing designed as an axial angular contact ball bearing.
Der Vertikalabschnitt, welcher der Energiezuführungsvorrichtung zuzurechnen ist, kann insbesondere seitlich an der verschiebbaren Plattform befestigt sein. Optional ist der Vertikalabschnitt höhenverstellbar, beispielsweise in der Art eines teleskopartig ausziehbaren Schachtes. The vertical section, which is to be attributed to the energy supply device, can in particular be attached laterally to the displaceable platform. Optionally, the vertical section is height-adjustable, for example in the manner of a telescopically extendable shaft.
Die Energiekette ist insbesondere zur Zuführung elektrischer Energie zum Energieabnehmer oder zu einer Mehrzahl an Energieabnehmern vorgesehen. Ebenso können Fluide, insbesondere ein Hydraulikmedium und/oder Druckluft, dem mindestens einen Energieabnehmer über die Energiekette zuführbar sein. The energy chain is intended in particular for supplying electrical energy to the energy consumer or to a plurality of energy consumers. Likewise, fluids, in particular a hydraulic medium and/or compressed air, can be supplied to the at least one energy consumer via the energy chain.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert. Hierin zeigen: An embodiment of the invention is explained in more detail below with reference to a drawing. In the drawing:

Fig. 10 das Linearsystem in der Einstellung nach Fig. 7 in perspektivischer Ansicht. Fig. 10 the linear system in the setting according to Fig. 7 in perspective view.
Ein insgesamt mit dem Bezugszeichen 1 gekennzeichnetes Linearsystem umfasst eine Plattform 2, welche auf Schienen 3 verfahrbar ist, wobei der gesamte lineare Verstellbereich der Plattform 2 mit LV angegeben ist. H bezeichnet die Höhe des gesamten Linearsystems 1 einschließlich einer Energiezuführungsvorrichtung 4. A linear system marked overall with the reference number 1 comprises a platform 2, which can be moved on rails 3, the entire linear adjustment range of the platform 2 being indicated as LV. H denotes the height of the entire linear system 1 including an energy supply device 4.
Die Energiezuführungsvorrichtung 4 umfasst einen Horizontalabschnitt 5, welcher kurz auch als Dreharm bezeichnet wird, sowie einen Vertikalabschnitt 6, der an der Platt- form 2 befestigt ist. Der Horizontalabschnitt 5 ist an einer Anschlussplatte 7 mit Hilfe eines Schwenklagers 19 gelagert. Das Schwenklager 19 ist im vorliegenden Fall als mehrreihiges Schrägkugellager gestaltet. Die durch das Schwenklager 19 gegebene vertikale Schwenkachse ist mit SP bezeichnet. Die Anschlussplatte 7 ist im Ausführungsbeispiel zur Deckenmontage vorgesehen. The energy supply device 4 comprises a horizontal section 5, which is also referred to as a rotating arm, and a vertical section 6, which is attached to the plate form 2. The horizontal section 5 is mounted on a connecting plate 7 with the aid of a pivot bearing 19. In this case, the pivot bearing 19 is designed as a multi-row angular contact ball bearing. The vertical pivot axis provided by the pivot bearing 19 is designated SP. In the embodiment, the connecting plate 7 is intended for ceiling mounting.
Der schwenkbare Horizontalabschnitt 5 umfasst ein flaches Gehäuse 8, welches parallel zur Anschlussplatte 7 angeordnet ist. Das Gehäuse 8 befindet sich damit knapp unterhalb der Decke des Raums, in welchem das Linearsystem 1 installiert ist. Entsprechendes gilt für ein Teleskoprohr 12, welches an das Gehäuse 8 anschließt und ebenfalls einen Abschnitt des Dreharms 5 darstellt. Ein zusammen mit dem Gehäuse 8 schwenkbares Trägerelement, an welchem das Teleskoprohr 12 gehalten ist, ist mit 14 bezeichnet. The pivotable horizontal section 5 includes a flat housing 8, which is arranged parallel to the connection plate 7. The housing 8 is therefore located just below the ceiling of the room in which the linear system 1 is installed. The same applies to a telescopic tube 12, which connects to the housing 8 and also represents a section of the rotating arm 5. A support element which can be pivoted together with the housing 8 and on which the telescopic tube 12 is held is designated 14.
Im Teleskoprohr 12 befindet sich eine Energiekette 10, die innerhalb des Gehäuses 8, wie aus den Figuren 2, 5, 9 hervorgeht, mindestens eine halbe um die Schwenkachse SP gelegte Windung beschreibt. Im vorliegenden Fall dient die Energiekette 10 der Zuführung elektrischer Energie zu einer Maschine, die auf der Plattform 2 montiert ist. Optional kann die Energiekettel 0 auch zur Zuführung von Hydraulikmedium und/oder Druckluft genutzt werden. In the telescopic tube 12 there is an energy chain 10, which describes at least half a turn placed around the pivot axis SP within the housing 8, as can be seen from FIGS. 2, 5, 9. In the present case, the energy chain 10 serves to supply electrical energy to a machine that is mounted on the platform 2. Optionally, the energy chain 0 can also be used to supply hydraulic medium and/or compressed air.
Die Energiekette 10 reicht von einem Befestigungspunkt 9 im Gehäuse 8 bis zu einem Befestigungspunkt 20 am vom Gehäuse 8 abgewandten Ende des Teleskoprohrs 12. Ein im Teleskoprohr 12 befindliche gerader Abschnitt der Energiekette 10 ist mit 13 bezeichnet. Innerhalb des Gehäuses 8 befindet sich ein gebogener Abschnitt 11 der Energiekette 10. Die Länge dieses gebogenen Abschnitts 11 ist, wie aus einem Vergleich der Figuren 2, 5, 9 hervorgeht, variabel. Durch das Gehäuse 8 wird somit ein Ausgleichsraum 17 für die Energiekette 10 bereitgestellt. Innerhalb des Teleskoprohrs 12 behält die Energiekette 10 stets ihre gerade Form. Am Ende des Teleskoprohrs 12 befindet sich ein Drehlager 15, mit welchem eine gelenkige Verbindung zum Vertikalabschnitt 6 hergestellt ist. Die damit gebildete Drehachse ist allgemein mit D bezeichnet. Kabel innerhalb des Vertikalabschnitts 6 sind nicht dargestellt. Am Übergang zwischen dem Horizontalabschnitt 5 und dem Verti- kalabschnitt 6 befindet sich ein Faltenbalg 16. Eine Höhenverstellung 18 ermöglicht eine Anpassung der Höhe des Vertikalabschnitts 6 an die Raumhöhe. The energy chain 10 extends from an attachment point 9 in the housing 8 to an attachment point 20 at the end of the telescopic tube 12 facing away from the housing 8. A straight section of the energy chain 10 located in the telescopic tube 12 is designated 13. Inside the housing 8 there is a curved section 11 of the energy chain 10. The length of this curved section 11 is variable, as can be seen from a comparison of Figures 2, 5, 9. The housing 8 thus provides a compensation space 17 for the energy chain 10. Within the telescopic tube 12, the energy chain 10 always maintains its straight shape. At the end of the telescopic tube 12 there is a pivot bearing 15, with which an articulated connection to the vertical section 6 is established. The axis of rotation thus formed is generally designated D. Cables within the vertical section 6 are not shown. There is a bellows 16 at the transition between the horizontal section 5 and the vertical section 6. A height adjustment 18 enables the height of the vertical section 6 to be adjusted to the height of the room.
Die Anschlussplatte 7 befindet sich ebenso wie das Gehäuse 8 seitlich neben der verschiebbaren Plattform 2. Der Abstand zwischen der Schwenkachse SP und der nächstgelegenen Schiene 3, in Draufsicht auf das Linearsystem 1 , ist mit DS bezeichnet. Der Abstand DS ist sowohl geringer als der lineare Verstellbereich LV als auch geringer der Abstand zwischen den beiden Schienen 3. The connection plate 7, like the housing 8, is located laterally next to the movable platform 2. The distance between the pivot axis SP and the nearest rail 3, in a top view of the linear system 1, is designated DS. The distance DS is smaller than the linear adjustment range LV as well as the distance between the two rails 3.
