Description

Die Erfindung bezieht sich auf eine Wickelvorrichtung gemäß Oberbegriff Patentanspruch 1.The invention relates to a winding device according to the preamble of claim 1.

U.a. in der Bühnentechnik, z.B. für Theaterbühnen sind Wickelvorrichtungen bekannt, mit denen Züge oder Hubseile motorisch auf Seiltrommeln auf- und abgewickelt werden, und zwar beispielsweise Hubseile für Bühnenelemente, wie Kulissen, aber auch zum Anheben oder Absenken von Personen usw.Et al in the stage technique, e.g. for theater stages winding devices are known, with which trains or hoisting ropes motorized on cable drums and are handled, for example, hoisting ropes for stage elements, such as scenes, but also for raising or lowering people, etc.

Allein schon aus Sicherheitsgründen ist es bei Wickelvorrichtungen oder Seilwinden vielfach gefordert, dass das Aufwickeln des jeweiligen Seils oder Hubseiles auf die zugehörige Wickeltrommel als zwangsweise geordnete einlagige Wicklung erfolgt, und zwar unter Einhaltung eines Seillaufwinkels innerhalb bestimmter Grenzen. Aufgabe der Erfindung ist es, eine Wickelvorrichtung aufzuzeigen, die diesen Erfordernissen voll gerecht wird und eine platzsparende Aufstellung ermöglicht.Already for safety reasons, it is often required in winding devices or winches that the winding of the respective rope or hoisting rope on the associated winding drum as compulsorily ordered single-layer winding is done, while maintaining a cable running angle within certain limits. The object of the invention is to show a winding device that fully meets these requirements and allows a space-saving installation.

Zur Lösung dieser Aufgabe ist eine Wickelvorrichtung entsprechend dem Patentanspruch 1 ausgebildet.To solve this problem, a winding device according to the patent claim 1 is formed.

Die erfindungsgemäße Wickelvorrichtung stellt das zwangsweise geordnete einlagige Aufwickeln des jeweiligen Seils oder Hubseiles auf die zugehörige Seiltrommel und die Einhaltung des Seillaufwinkels innerhalb vorgegebener Grenzen dadurch sichert, dass der die wenigstens eine Seiltrommel aufweisende Schlitten synchron mit der Drehbewegung mit der Seiltrommel in deren Achsrichtung bewegt wird, und zwar der Steigung der einlagigen Wicklung entsprechend, und dass außerdem das Seil der Seiltrommel beim Auf- und Abwickeln radial zuläuft, und zwar beispielsweise über eine sich mit dem Schlitten nicht mitbewegende Umlenkrolle. Die Hubbewegung des Schlittens ist dabei eine vertikale Hubbewegung, sodass sich die Möglichkeit einer äußerst platzsparenden Aufstellung der Wickelvorrichtung ergibt, was insbesondere auch für den Einsatz in der Bühnentechnik von großer Bedeutung ist.The winding device according to the invention provides the compulsorily ordered single-layer winding of the respective cable or hoist rope on the associated cable drum and compliance with the cable running angle within predetermined limits thereby ensures that the at least one cable drum having carriage is moved synchronously with the rotational movement with the cable drum in the axial direction, namely, the slope of the single-layer winding accordingly, and that also the rope of the cable drum when winding and unwinding radially tapers, for example via a not moving with the carriage pulley. The lifting movement of the carriage is a vertical lifting movement, so that there is the possibility of extremely space-saving installation of the winding device, which is particularly important for use in the stage technology of great importance.

Durch eine Gewichtsentlastungseinrichtung ist das Gewicht des Schlittens, einschließlich sämtlicher an diesem Schlitten vorgesehener Elemente kompensiert oder zumindest aber soweit kompensiert, dass für die vertikale Bewegung des Schlittens nur geringe Kräfte erforderlich sind, d.h. für die vertikale Hubbewegung ein nur niedrig belasteter Hubantrieb ausreicht. Dieser kann beispielsweise als niedrig belasteter Spindelantrieb ausgebildet sein.By a weight relief device, the weight of the carriage, including all provided on this slide elements is compensated or at least compensated so far that the vertical movement of the carriage only small forces are required, i. for the vertical lifting movement only a low-loaded lifting drive is sufficient. This can be designed for example as a low-loaded spindle drive.

Bei einer bevorzugten Ausführungsform der Erfindung ist der Hubantrieb in besonders einfacher Weise dadurch realisiert, dass wenigstens ein mit dem Schlitten nicht mitbewegter Mitnehmer in die an der wenigstens einen Seiltrommel ausgebildete, die Achse dieser Seiltrommel wendelartig umschließenden Seilnut für das auf- und abzuwickelnde Hubseil eingreift.In a preferred embodiment of the invention, the lifting drive is realized in a particularly simple manner in that at least one driver not moved along with the carriage engages in the cable groove formed on the at least one cable drum and encloses the axis of this cable drum in a spiral manner for the hoisting cable to be wound up and unwound.

Weiterbildungen, Vorteile und Anwendungsmöglichkeiten der Erfindung ergeben sich auch aus der nachfolgenden Beschreibung von Ausführungsbeispielen und aus den Figuren. Dabei sind alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger Kombination grundsätzlich Gegenstand der Erfindung, unabhängig von ihrer Zusammenfassung in den Ansprüchen oder deren Rückbeziehung. Auch wird der Inhalt der Ansprüche zu einem Bestandteil der Beschreibung gemacht.Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures. In this case, all described and / or illustrated features alone or in any combination are fundamentally the subject of the invention, regardless of their summary in the claims or their dependency. Also, the content of the claims is made an integral part of the description.

Die Erfindung wird im Folgenden anhand der Figuren an einem Ausführungsbeispiel näher erläutert. Es zeigen:

Fig. 1 und 2
jeweils in vereinfachter Darstellung eine Wickelvorrichtung für Hubseile in zwei unterschiedlichen Betriebszuständen;
Fig. 3
in vereinfachter schematischer Darstellung eine der Seiltrommeln der Vorrichtung der Figuren 1 und 2 zusammen mit einer mit einer mit einer Seilnut kämmenden Element der Vorrichtung.
The invention will be explained in more detail below with reference to the figures of an embodiment. Show it:
Fig. 1 and 2
each in a simplified representation of a winding device for hoisting ropes in two different operating conditions;
Fig. 3
in a simplified schematic representation of the cable drums of the device Figures 1 and 2 together with an element of the device which meshes with a cable groove.

Die in den Figuren allgemein mit 1 bezeichnete Seilwinde bzw. Wickelvorrichtung besteht im Wesentlichen aus einem an einer vertikalen Führung 2 geführten Schlitten 3, auf welchem eine Welle 4 beidendig drehbar gelagert ist, und zwar derart, dass diese Welle 4 mit ihrer Achse in vertikaler Richtung und damit parallel zur Führung 2 orientiert ist. Auf der Welle 4 sind drei Seiltrommeln 5, 6 und 7 vorgesehen, und zwar jeweils zum einlagigen Aufwickeln eines Hubseils 8.The generally designated 1 in the figures winch or winding device consists essentially of a guided on a vertical guide 2 carriages 3, on which a shaft 4 is rotatably mounted at both ends, in such a way that this shaft 4 is oriented with its axis in the vertical direction and thus parallel to the guide 2. On the shaft 4, three cable drums 5, 6 and 7 are provided, in each case for the single-layer winding of a hoisting cable 8.

Die drei Hubseile 8 sind bei der dargestellten Ausführungsform über drei in den Figuren 1 und 2 achsgleich hintereinander angeordnete obere Umlenkrollen 9 geführt, über die die zunächst horizontal verlaufenden Hubseile 8 vertikal umgelenkt werden. Jedes Hubseil 8 ist dann über eine weitere Umlenkrolle 10 geführt, sodass es horizontal oder im Wesentlichen horizontal der zugehörigen Seiltrommel 5 - 7 zuläuft. Da die Seiltrommel 5 - 7 an der gemeinsamen Welle 4 in Achsrichtung dieser Welle, d.h. in vertikaler Richtung gegeneinander versetzt vorgesehen sind, sind auch die Umlenkrollen 10 in vertikaler Richtung gegeneinander versetzt angeordnet. Sämtliche Umlenkrollen 10 sind mit ihren horizontalen Achsen parallel zueinander orientiert an der Führung 2 bzw. an dort vorgesehenen Lagern frei drehbar gelagert. Durch das Zuführen der Hubseile 8 über die Umlenkrollen 10 in horizontaler Richtung und damit radial oder im Wesentlichen radial zur Achse der Welle 4 wirken Zugkräfte der Hubseile 4 beispielsweise bedingt durch das mit diesen Hubseilen zu hebende Gewicht ausschließlich radial und nicht axial auf die Welle 4 und den Schlitten 3.The three hoisting ropes 8 are in the illustrated embodiment, three in the Figures 1 and 2 coaxially arranged one behind the other upper guide rollers 9, over which the first horizontally extending hoisting ropes 8 are deflected vertically. Each hoist rope 8 is then guided over a further deflection roller 10, so that it runs horizontally or substantially horizontally of the associated cable drum 5-7. Since the cable drum 5-7 on the common shaft 4 in the axial direction of this shaft, that are provided offset from one another in the vertical direction, the guide rollers 10 are arranged offset from each other in the vertical direction. All pulleys 10 are oriented with their horizontal axes parallel to each other on the guide 2 and freely rotatably supported there provided bearings. By supplying the hoisting ropes 8 via the guide rollers 10 in the horizontal direction and thus radially or substantially radially to the axis of the shaft 4, tensile forces of the hoisting ropes 4, for example due to the weight to be lifted with these hoisting ropes, act exclusively radially and not axially on the shaft 4 and the carriage 3.

An dem Schlitten 4 ist weiterhin der u.a. von einem Elektromotor und einem Getriebe gebildete Antrieb der Wickelvorrichtung 1 bzw. für die Welle 4 und die dortigen Seiltrommeln 5 - 7 vorgesehen. Zur Kompensation des Gesamtgewichts des Schlittens 3 einschließlich der an diesem Schlitten vorgesehenen Elemente, insbesondere auch der Welle 4 mit den Seiltrommeln 5 - 7 und des Antriebs 11, ist eine Kompensationseinrichtung 12 vorgesehen, die bei der dargestellten Ausführungsform im Wesentlichen aus einem doppelarmigen Schwenkhebel 13 besteht, der zwischen seinen beiden Enden 13.1 und 13.2 um eine horizontale Achse 14 parallel zu den Achsen der Umlenkrollen 9 und 10 schwenkbar an der vertikalen Führung 2 gehalten ist und mit dem mit einer Rolle 15 versehenen Hebelarm 13.1 eine Abstützung für die Unterseite des Schlittens 3 bildet und mit seinem anderen Ende bzw. Hebelarm 13.2 mit wenigstens einer Gasfeder 16 verbunden ist, die zwischen diesem Ende des Hebels 13 und der vertikalen Führung 2 wirkt. Für die Rolle 15 ist an der Unterseite des Schlittens 3 ein mit dieser Rolle zusammenführende Gleitführung 15.1 vorgesehen.On the carriage 4 of the further example of an electric motor and a gear drive formed the winding device 1 and for the shaft 4 and the local cable drums 5-7 are provided. To compensate for the total weight of the carriage 3 including the provided on this slide elements, in particular the shaft 4 with the cable drums 5-7 and the drive 11, a compensation device 12 is provided, which consists in the illustrated embodiment essentially of a double-armed pivot lever 13 which is held between its two ends 13.1 and 13.2 about a horizontal axis 14 parallel to the axes of the guide rollers 9 and 10 pivotally mounted on the vertical guide 2 and with the roller 15 provided with a lever arm 13.1 forms a support for the underside of the carriage 3 and with its other end or lever arm 13.2 is connected to at least one gas spring 16 which acts between this end of the lever 13 and the vertical guide 2. For the roller 15 is provided on the underside of the carriage 3 a merging with this roller sliding guide 15.1.

Durch entsprechende Wahl der Gasfeder 16 und des durch den Hebel 13 bzw. dessen Hebelarme 13.1 und 13.2 bewirkten Übersetzungsverhältnis ist die Gewichtskompensationseinrichtung 12 so eingestellt, dass das gesamte Gewicht des Schlittens 3 und der an diesem Schlitten vorgesehenen Funktionselemente kompensiert bzw. weitestgehend kompensiert ist.By appropriate selection of the gas spring 16 and the ratio caused by the lever 13 and its lever arms 13.1 and 13.2, the weight compensation device 12 is adjusted so that the total weight of the carriage 3 and provided on this slide functional elements is compensated or largely compensated.

Um Toleranzen der Gasfeder 16 sowie Gewichtstolleranzen des Schlittens 3 und der an diesem vorgesehenen Funktionselemente auszugleichen, ist die Gewichtsentlastung der Gewichtskompensationseinrichtung 12 einstellbar, und zwar bei der dargestellten Ausführungsform dadurch, dass der Angriffspunkt der Gasfeder 16 am Hebelarm 13.2 radial zum Schwenkpunkt 14 einstellbar ist, wie dies in den Figuren 1 und 2 durch das dortige Langloch 13.2.1 angedeutet ist.In order to compensate for tolerances of the gas spring 16 and weight tolerances of the carriage 3 and the functional elements provided on this, the weight relief of the weight compensation device 12 is adjustable, in the illustrated embodiment in that the point of application of the gas spring 16 on the lever arm 13.2 is radially adjustable to the pivot point 14, like this in the Figures 1 and 2 is indicated by the local slot 13.2.1.

Durch die Kompensation des Gewichtes des Schlittens 3 und der an diesem Schlitten vorgesehenen Funktionselement ist es in besonders einfacher Weise möglich, den gesamten Schlitten 3 in vertikaler Richtung an der Führung 2 auf und ab zu bewegen (Doppelpfeil A), um dadurch das erforderliche einlagige Aufwickeln der Hubseile 8 auf der jeweiligen Seiltrommel 5 bzw. 6 sowie das Abwickeln der Hubseile von diesen Seiltrommeln 5 - 7 bei mit dem Schlitten 3 nicht mitbewegten Umlenkrollen 10 zu erreichen. Die für das einlagige bzw. gewendelte Aufwickeln der Hubseile 8 auf den Seiltrommeln 5 - 7 erforderliche, mit der Drehbewegung der Welle 4 synchronisierte Bewegen des Schlittens 3 ist mit einem einfachen Spindelantrieb erreichbar, beispielsweise unter Verwendung einer Gewindespindel 17, die ebenfalls beidendig am Schlitten 3 drehbar gelagert ist, mit ihrer Achse in vertikaler Richtung und damit parallel zur Welle 4 und zur Führung 2 orientiert ist und durch den Antrieb 11 angetrieben wird. Die Spindel 17 wirkt mit einem Muttergewindestück zusammen, welches an der Führung 2 bzw. an einem über die Führung 2 wegstehenden Tragarm 18 vorgesehen ist.By compensating for the weight of the carriage 3 and the functional element provided on this carriage, it is possible in a particularly simple manner to move the entire carriage 3 up and down in the vertical direction on the guide 2 (double arrow A), thereby providing the required single-layer winding the hoisting ropes 8 on the respective cable drum 5 and 6, and the unwinding of the hoisting ropes of these cable drums 5 - 7 to reach at the carriage 3 not mitbewegten pulleys 10. For the single-layer or coiled winding of the hoisting ropes 8 on the cable drums 5-7 required, synchronized with the rotational movement of the shaft 4 moving the carriage 3 can be reached with a simple spindle drive, for example using a threaded spindle 17, which is also at both ends of the carriage is rotatably supported, with its axis in the vertical direction and thus oriented parallel to the shaft 4 and the guide 2 and is driven by the drive 11. The spindle 17 cooperates with a nut threaded piece, which is provided on the guide 2 or on a projecting beyond the guide 2 supporting arm 18.

Die Figur 3 zeigt nochmals in sehr vereinfachter Teildarstellung eine der Seiltrommeln 5, 6 bzw. 7. Zum ordnungsgemäßen Aufwickeln des jeweiligen Hubseiles 8 ist jede Seiltrommel an ihrer Umfangsfläche mit einer Seilnut 19 versehen, die sich wendelartig um die Achse der Seiltrommel 5, 6 bzw. 7 erstreckt und zur einlagigen Aufnahme des betreffenden Hubseiles 8 ausgebildet ist.The FIG. 3 shows again in a very simplified partial representation of the cable drums 5, 6 and 7. For proper winding of the respective hoist rope 8 each cable drum is provided on its peripheral surface with a cable groove 19 which extends helically around the axis of the cable drum 5, 6 and 7 respectively and for single-layer recording of the relevant hoist rope 8 is formed.

Vorstehend wurde davon ausgegangen, dass die Hubbewegung des Schlittens 3 über die nur gering belastete Gewindespindel 17 erfolgt. Die Figur 3 zeigt einen in die Seilnuten 19 einer Seiltrommel 5, 6 bzw. 7 eingreifenden Mitnehmer 20, der an der Führung 2 mit dem Schlitten 3 nicht mitbewegt befestigt ist, sodass beim Drehen der Welle 4 über diesen in die spiralförmige Seilnut 19 eingreifenden Mitnehmer 20 die Hubbewegung des Schlittens 3 beim einlagigen Aufwickeln der Hubseile 8 auf die Seiltrommeln 5, 6 und 7 bzw. in die dortigen Seilnuten 19 und beim Abwickeln der Hubseile 8 von den Seiltrommeln 5 - 7 erzeugt wird. Der Mitnehmer 20 besteht vorzugsweise aus einem im Vergleich zum Material der Seiltrommel (beispielsweise Stahl) sehr viel weicheren Material, z.B. aus Kunststoff. Dies ist durch die - Gewichtsentlastung des Schlittens 3 durch die Gewichtskompensationseinrichtung 12 mögl ich.Above, it was assumed that the lifting movement of the carriage 3 takes place via the only slightly loaded threaded spindle 17. The FIG. 3 shows a in the rope grooves 19 of a cable drum 5, 6 and 7 engaging driver 20 which is not moved along the guide 2 with the carriage 3, so that upon rotation of the shaft 4 via this engaging in the spiral cable groove 19 driver 20, the lifting movement of the carriage 3 in the single-layer winding of the hoisting ropes 8 on the cable drums 5, 6 and 7 or in the local cable grooves 19 and the unwinding of the hoisting ropes 8 of the cable drums 5 - 7 is generated. The driver 20 is preferably made of a material which is much softer compared to the material of the cable drum (for example steel), for example of plastic. This is possible by the weight reduction of the carriage 3 by the weight compensation device 12.

Die Erfindung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, dass zahlreiche Änderungen sowie Abwandlungen möglich sind, ohne dass dadurch der der Erfindung zugrunde liegende Erfindungsgedanke verlassen wird. So wurde vorstehend davon ausgegangen, dass mit dem Schlitten 3 die gesamte Seilwinde im Wesentlichen bestehend aus der Welle 4, den dortigen Seiltrommeln 5 - 7 und dem Antrieb 11, einschließlich der den Schlittenhub bewirkenden Elemente (insbesondere Gewindespindel 17) und der zugehörigen Antriebe in vertikaler Richtung bewegt wird. Bei einer entsprechenden Ausbildung der antriebsmäßigen Verbindung besteht auch die Möglichkeit, den Antrieb 11 mit dem Schlitten 3 nicht mitbewegt, z.B. an der Führung 2 vorzusehen und für das einlagige Aufwickeln der Hubseile 8 auf den Seiltrommeln 5 - 7 lediglich den Schlitten 3 mit diesen Seiltrommeln und der gemeinsamen Welle 4 zu bewegen.The invention has been described above by means of an embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention. So it was assumed above that with the carriage 3, the entire winch essentially consisting of the shaft 4, the local rope drums 5-7 and the drive 11, including the carriage stroke causing elements (in particular threaded spindle 17) and the associated drives in vertical Direction is being moved. In a corresponding embodiment of the drive connection there is also the possibility that the drive 11 is not moved with the carriage 3, for example provided on the guide 2 and for the single-layer winding of the Hoisting cables 8 on the cable drums 5 - 7 only to move the carriage 3 with these cable drums and the common shaft 4.

Weiterhin wurde vorstehend davon ausgegangen, dass insgesamt drei Seiltrommeln 5 - 7 an der gemeinsamen Welle 4 vorgesehen sind. Selbstverständlich kann die Anzahl der Seiltrommeln hiervon auch abweichend gewählt sein und/oder es ist möglich, mehrere Wellen für jeweils eine oder aber mehrere Seiltrommeln am Schlitten 3 vorzusehen.Furthermore, it was assumed above that a total of three cable drums 5 - 7 are provided on the common shaft 4. Of course, the number of cable drums hereof may also be chosen differently and / or it is possible to provide several waves for one or more cable drums on the carriage 3.

Weiterhin wurde vorstehend davon ausgegangen, dass die Gewichtskompensationseinrichtung 12 aus einem Hebel 13 und einer Gasfeder 16 besteht. Selbstverständlich können auch mehrere Schwenkhebel 13 und mehrere Gasfedern 16 oder anders wirkende Federelemente vorgesehen sein. Anstelle hiervon oder zusätzlich hierzu kann eine Gewichtsentlastung auch durch einen beispielsweise ein Ausgleichsgewicht oder wenigstens ein Ausgleichsfederelemente aufweisenden Entlastungsseilzug erfolgen.Furthermore, it was assumed above that the weight compensation device 12 consists of a lever 13 and a gas spring 16. Of course, several pivot lever 13 and a plurality of gas springs 16 or other acting spring elements can be provided. Instead of or in addition to this, a weight reduction can also take place by means of, for example, a balance weight or at least one compensating spring element having a relief cable.
