Description

Antriebseinheit für mindestens ein Zugmittel  Drive unit for at least one traction means
Die Erfindung betrifft eine Antriebseinheit für mindestens ein Zugmittel wie Zugseil oder - band, insbesondere in der Bühnentechnik, mit einer Wickeltrommel, die mindestens einen Aufhahrnebereich aufweist, auf dem (jeweils) ein auf- oder abwickelbares Zugmittel aufgenommen ist. The invention relates to a drive unit for at least one traction means such as traction cable or - band, in particular in the stage technology, with a winding drum having at least one Aufhahrnebereich on which (each) an up or unwound traction means is added.
Aus der DE 10 2005 049 105 AI ist eine Antriebseinheit für Hubsysteme für die Bühnentechnik bekannt geworden, bei der zum Anheben und Absenken einer Last als Zugmittel ein Flachriemen verwendet wird. Obwohl eine derartige Ausführungsform im Hinblick auf die erzielbare kurze axiale Baulänge vorteilhaft ist, besteht ein gravierender Nachteil darin, dass die Antriebseinheit zur Erzeugung eines großen Drehmoments ausgebildet sein muss, um die Wickeltrommel auch dann noch gegen die Zugkraft der Last drehen zu können, wenn bereits eine gewisse bzw. erhebliche Länge des Flachriemens aufgewickelt worden ist und somit ein beträchtlicher effektiver Durchmesser erreicht worden ist. From DE 10 2005 049 105 AI a drive unit for lifting systems for the stage technology has become known, in which for lifting and lowering a load as a traction means a flat belt is used. Although such an embodiment is advantageous in view of the achievable short axial length, there is a serious disadvantage in that the drive unit must be designed to generate a large torque in order to rotate the winding drum even against the tensile force of the load, if already a certain or significant length of the flat belt has been wound and thus a considerable effective diameter has been achieved.
Die Aufgabe der Erfindung besteht darin, den genannten Nachteil des Stands der Technik zu vermeiden, und eine Antriebseinheit für mindestens ein Zugmittel dahingehend zu verbessern, dass bei kurzer axialer Baulänge eine relativ kleine Getriebeeinheit für den Antrieb genügt. The object of the invention is to avoid the mentioned disadvantage of the prior art, and to improve a drive unit for at least one traction means to the effect that with a short axial length a relatively small gear unit is sufficient for the drive.
Diese Aufgabe wird bei einer gattungsgemäßen Antriebseinheit dadurch gelöst, das axial benachbart zu dem Aufnahmebereich ein zylindrischer Antriebsbereich auf der Wickeltrommel angeordnet ist, auf dem ein auf- oder abwickelbares bandförmiges Antriebsmittel aufgenommen ist, dass unter Erzeugung eines auf die Wickeltrommel wirkenden Antriebsmoments auf einer antreibbaren Antriebstrommel aufwickelbar oder, die Wickeltrommel freigebend, von der Antriebstrommel abwickelbar ist. This object is achieved in a generic drive unit characterized in that axially adjacent to the receiving area a cylindrical drive portion is arranged on the winding drum, on which an up or unwindable belt-shaped drive means is received, that generating a acting on the winding drum drive torque on a drivable drive drum windable or, releasing the winding drum, can be unwound from the drive drum.
|Bestätigungskopie| Erfindungsgemäß wird also vermieden, die Wickeltrommel unter Erzeugung eines notwendigerweise großen Drehmoments über ihre Achse in Drehung zu versetzen. Stattdessen wird die Wickeltrommel durch die Zugkraft eines auf sie selbst aufgewickelten bandförmigen Antriebsmittels in Drehung versetzt, wobei eine vergleichsweise geringe Zugkraft eines Antriebsmittels ausreicht. Ein derartiger Antrieb ist zudem ausgesprochen geräuscharm, was bei Anwendungen in der Bühnentechnik von wesentlicher Bedeutung ist. | Confirmation copy | According to the invention is thus avoided to enable the winding drum to generate a necessarily large torque about its axis in rotation. Instead, the winding drum is rotated by the tensile force of a self-wound on itself ribbon-shaped drive means in rotation, with a comparatively low tensile force of a drive means is sufficient. Such a drive is also extremely quiet, which is essential in applications in the stage technology.
Es kann vorgesehen sein, dass die Wickeltrommel mindestens einen zylindrischen Aufhah- mebereich zum Aufwickeln einer Anzahl von axial nebeneinander liegenden Windungen des Zugmittels aufweist. Dies hat den Vorteil eines konstanten Antriebsmoments, allerdings u. U. den Nachteil einer vergleichsweise großen axialen Baulänge. It can be provided that the winding drum has at least one cylindrical receiving area for winding up a number of axially adjacent turns of the pulling means. This has the advantage of a constant drive torque, but u. U. the disadvantage of a comparatively large axial length.
Alternativ besteht die Möglichkeit, dass die Wickeltrommel mindestens einen radial verlaufenden schlitzförmigen Aufhahmebereich aufweist, dessen axiale Breite gleich oder geringfügig größer als ein Durchmesser oder eine Breite des Zugmittels ist, zum Aufnehmen einer Anzahl von in radialer Richtung übereinanderliegenden Windungen des Zugmittels. Diese Ausführung hat den Vorteil einer kleinen axialen Baulänge, wobei allerdings das Antriebsmoment aufgrund des veränderlichen effektiven Wickeldurchmessers des Zugmittels ebenfalls veränderlich ist. Alternatively, there is the possibility that the winding drum has at least one radially extending slot-shaped receiving area whose axial width is equal to or slightly greater than a diameter or a width of the traction means, for receiving a number of superimposed turns of the traction means in the radial direction. This embodiment has the advantage of a small axial length, although the drive torque is also variable due to the variable effective winding diameter of the traction means.
Unabhängig von der konkreten Ausbildung kann der Aufhahmebereich einen Basisdurchmesser von 0,3 Meter bis 2 Meter, insbesondere 0,7 Meter bis 1 ,2 Meter, aufweisen, wobei dies bei einem zylindrischen Aufhahmebereich dessen Durchmesser und bei einem radial verlaufenden schlitzförmigen Aufhahmebereich dessen kleinster Durchmesser ist. Regardless of the specific training, the Aufhahmebereich may have a base diameter of 0.3 meters to 2 meters, in particular 0.7 meters to 1, 2 meters, this being at a cylindrical Aufhahmebereich whose diameter and at a radially extending slot-shaped Aufhahmebereich whose smallest diameter is.
Weiter kann vorgesehen sein, dass der zylindrische Antriebsbereich einen Durchmesser von 0,3 Meter bis 2 Meter, insbesondere 0,7 Meter bis 1,2 Meter, aufweist, wobei zu diesem Durchmesser im Betrieb die Dicke des jeweils bereits aufgewickelten Antriebsmittels hinzukommt, woraus sich dann ein effektiver Durchmesser ergibt. It can further be provided that the cylindrical drive region has a diameter of 0.3 meters to 2 meters, in particular 0.7 meters to 1.2 meters, to which diameter in operation the thickness of each already wound drive means is added, from which then gives an effective diameter.
Das Antriebsmittel ist bevorzugt ein Stahlband einer Breite von 5 mm bis 50 mm und einer Dicke von 0,05 bis 0,5 mm. Auf dem zylindrischen Antriebsbereich der Wickeltrommel kann zusätzlich ein bandförmiges Sicherungsmittel aufgenommen sein, beispielsweise ebenfalls ein Stahlband, das gleichzeitig mit dem Antriebsmittel von der Antriebstrommel auf ehmbar oder von dieser abwickelbar ist. Sollte das Antriebsmittel oder das Sicherungsmittel versagen oder reißen, steht noch das jeweils andere, intakte Antriebs- oder Sicherungsmittel zur Verfügung. The drive means is preferably a steel strip having a width of 5 mm to 50 mm and a thickness of 0.05 to 0.5 mm. In addition, a band-shaped securing means may be accommodated on the cylindrical drive region of the winding drum, for example likewise a steel strip which can be unwound or unwound from the drive drum simultaneously with the drive means. Should the drive means or the securing means fail or break, the other, intact drive or securing means is still available.
Es kann vorgesehen sein, dass der Antriebstrommel ein selbsthemmendes Getriebe und/oder zwei unabhängige Bremsen zugeordnet sind. It can be provided that the drive drum is associated with a self-locking gear and / or two independent brakes.
Insbesondere kann vorgesehen sein, dass die Wickeltrommel mit einer Torsionsspannfeder gekoppelt ist, die die Wickeltrommel entgegen einer das mindestens eine Zugmittel spannenden Drehrichtung vorspannt. Dadurch wird vermieden, dass bei nachlassender Zugmittelspannung das auf der Wickeltrommel aufgewickelte Antriebsmittel seinerseits an Spannung verliert und sich in unerwünschter Weise von der Wickeltrommel bzw. von dem Antriebsbereich löst. In particular, it can be provided that the winding drum is coupled with a Torsionsspannfeder biasing the winding drum against a tensioning the at least one traction rotational direction. This avoids that with decreasing tension means wound on the winding drum drive means in turn loses tension and dissolves undesirably from the winding drum or from the drive area.
Die Aufgabe der Erfindung wird weiterhin durch einen Prospektzug mit mehreren erfindungsgemäßen Antriebseinheiten gelöst, die axial nebeneinander in Abständen von höchstens 30 cm, höchstens 25 cm oder höchstens 20 cm angeordnet sein können. Die erfindungsgemäße Bauform ermöglicht vergleichsweise geringe gegenseitige Abstände benachbarter Antriebseinheiten. The object of the invention is further achieved by a brochure train with a plurality of drive units according to the invention, which can be arranged axially next to one another at intervals of at most 30 cm, at most 25 cm or at most 20 cm. The design according to the invention allows comparatively small mutual distances of adjacent drive units.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels, wobei auf eine Zeichnung Bezug genommen ist, in der Further advantages and features of the invention will become apparent from the following description of an embodiment, reference being made to a drawing in which

Fig. 2 eine schematische Seitenansicht in axialer Richtung zeigt, Fig. 2 shows a schematic side view in the axial direction,
Fig. 3 eine Seitenansicht eines Prospektzugs mit einer erfindungsgemäßen Antriebseinheit zeigt Fig. 3 shows a side view of a Prospektzugs with a drive unit according to the invention
Fig. 4 schematisch eine Einbausituation einer erfindungsgemäßen Antriebseinheit als Ersatz eines Handkonterzugs innerhalb einer Reihe mehrerer Handkonterzüge zeigt. Fig. 1 zeigt in einer perspektivischen Ansicht eine vollständige Antriebseinheit für einen Prospektzug in der Bühnentechnik, mit einer Wickeltrommel 2, die um eine Drehachse 4 drehbar angetrieben ist. Die Wickeltrommel 2 weist sechs unmittelbar nebeneinander angeordnete Aufhahmebereiche 6 für einzelne Zugmittel, hier Zugseile 8 auf, die in Form von radial zur Drehachse 4 verlaufenden schlitzförmigen oder zylinderringformigen Aufhahmeräu- men mit Basisdurchmesser d ausgebildet sind und durch schmale, jeweils dazwischen angeordnete Zwischenwände 10 voneinander getrennt sind. Eine lichte Breite B eines jeden Aufnahmebereichs 6 entspricht einem Durchmesser D eines darin aufgenommenen Zugseils (oder einer Breite eines Zugbands) oder ist geringfügig größer, so dass das jeweilige Zugmittel problemlos in einem Aufnahmebereich 6 aufgewickelt werden kann. Zu diesem Zweck ist ein wickeltrommelseitiges Ende jedes Zugmittels 8 am Grund seines Auf ahmebereichs 6 an der Wickeltrommel 2 fixiert und wird beim Aufwickeln in radial übereinander liegenden Windungen aufgenommen, ohne dass es axial ausweichen kann. Alternativ kann ein oder können mehrere Zugbänder anstelle von Zugseilen zum Einsatz kommen, etwa in Form von Stahlbändern. Fig. 4 shows schematically an installation situation of a drive unit according to the invention as a replacement for a hand-held counter-train within a series of several hand-held counterparts. Fig. 1 shows a perspective view of a complete drive unit for a brochure train in stage technology, with a winding drum 2, which is rotatably driven about a rotation axis 4. The winding drum 2 has six immediately adjacent arranged Aufhahmebereiche 6 for individual traction means, here pull cables 8, which are formed in the form of radially extending to the rotation axis 4 slot-shaped or zylinderringformigen Aufhahmeräu- men with base diameter d and separated by narrow, each interposed intermediate walls 10 are. A clear width B of each receiving area 6 corresponds to a diameter D of a traction cable (or a width of a tension band) accommodated therein or is slightly larger, so that the respective traction means can be wound up without difficulty in a receiving area 6. For this purpose, a winding drum-side end of each traction means 8 is fixed to the base of its on ahmebereichs 6 on the winding drum 2 and is taken up during winding in radially superimposed turns, without it can dodge axially. Alternatively, one or more drawstrings can be used instead of pull ropes, for example in the form of steel bands.
Obwohl die einzelnen Zugseile 8 und ihre Aufhahmebereiche 6 in dem dargestellten Beispiel gleichen Durchmesser D bzw. gleiche Breite B aufweisen, besteht die Möglichkeit, unterschiedliche Seildurchmesser (oder Zugbandbreiten) in unterschiedlich breiten Aufhahmebe- reichen einzusetzen, wenn damit aufgrund der resultierenden unterschiedlichen Festigkeiten und/oder unterschiedlichen Aufwickelgeschwindigkeit bzw. Aufwickelwege bestimmte Wirkungen erzielt werden sollen. Although the individual traction ropes 8 and their receiving regions 6 in the illustrated example have the same diameter D or the same width B, it is possible to use different rope diameters (or tensile belt widths) in different widths of receiving areas, if due to the resulting different strengths and / or or different winding speed or Aufwickelwege certain effects to be achieved.
Ferner besteht bei Zugseilen die Möglichkeit, anstelle der dargestellten Aufwicklung in radial übereinanderliegenden spiralförmig im Durchmesser zunehmenden Windungen eine Aufwicklung in axial nebeneinander liegenden Windungen gleichen Durchmessers vorzusehen, wobei dann allerdings die axiale Baulänge der Wickeltrommel und der Antriebseinheit als Ganzes zunimmt. Dies kann im Einzelfall zweckmäßig sein, wenn gleichmäßige, d.h. vom Aufwickel zustand unabhängige Wickelgeschwindigkeiten bzw. Aufwickel wege je Wickel - trommelumdrehung erzielt werden sollen. Furthermore, there is the possibility for pull ropes, instead of the winding shown in radially superimposed spiral diameter increasing turns to provide a winding in axially adjacent turns of the same diameter, in which case, however, the axial length of the winding drum and the drive unit increases as a whole. This may be appropriate in a particular case when uniform, i. winding condition independent winding speeds or winding paths per winding - drum rotation to be achieved.
Der Antrieb der Wickeltrommel 2 erfolgt über ein bandförmiges Antriebsmittel 12, das als Stahlband ausgeführt sein kann. Das Antriebsmittel 12 ist auf einem zylindrischen Antriebsbereich 14 der Wickeltrommel 2 aufgenommen, wobei ein wickeltrommelseitiger Endab- schnitt des Antriebsmittels 12 an der Wickeltrommel 2 fixiert ist. Das Antriebsmittel 12 verläuft über eine Umlenkrolle 16 zu einer Antriebstrommel 18, die grundsätzlich manuell oder motorisch angetrieben sein kann und im dargestellten Ausführungsb ei spiel von einem Getriebemotor 20 wahlweise in Antriebs- oder Freigaberichtung antreibbar ist. The drive of the winding drum 2 via a belt-shaped drive means 12, which may be designed as a steel strip. The drive means 12 is received on a cylindrical drive region 14 of the winding drum 2, wherein a winding drum-side end section of the drive means 12 is fixed to the winding drum 2. The drive means 12 extends over a pulley 16 to a drive drum 18, which can be driven in principle manually or by motor and in the illustrated Ausführungsb egg game of a geared motor 20 is selectively driven in the drive or release direction.
Der Getriebemotor 20 kann ein dynamisch selbsthemmendes oder selbstsperrendes Getriebe, beispielsweise Schneckengetriebe, aufweisen, und er kann zusätzlich oder alternativ mit zwei unabhängig wirkenden Bremsen versehen sein. The gear motor 20 may include a dynamically self-locking or self-locking gear, such as worm gears, and may additionally or alternatively be provided with two independently acting brakes.
Zusätzlich zu dem Antriebsmittel 12 verfügt die Antriebseinheit über ein bandförmiges Sicherungsmittel 24, das ebenso wie das Antriebsmittel 12 auf dem Antriebsbereich 14 der Wickeltrommel 2 aufgenommen und mit einem wickeltrommelseitigen Ende an der Wickeltrommel fixiert ist. Das Sicherungsmittel 24 dient dazu, im Falle eines Versagens, Reißens o.ä. des Antriebsmittels 12 zu verhindern, dass sich die Zugmittel 8 unkontrolliert abwickeln können. Das Sicherungsmittel 24 ist über eine federbelastete und die Straffheit des Sicherungsmittels 24 gewährleistende Umlenkrolle 26 zu der Antriebstrommel 8 geführt, auf der es ebenso wie das Antriebsmittel 12 endseitig fixiert ist und bei Drehung der Antriebstrommel 18 gleichzeitig und mit gleicher Geschwindigkeit wie das Antriebsmittei 12 aufgewickelt wird. In addition to the drive means 12, the drive unit has a band-shaped securing means 24 which, like the drive means 12, is received on the drive region 14 of the winding drum 2 and fixed to the winding drum with a winding drum-side end. The securing means 24 serves in the event of failure, cracking or the like. the drive means 12 to prevent that the traction means 8 can uncontrollably unwind. The securing means 24 is guided via a spring-loaded and the tightness of the securing means 24 ensuring pulley 26 to the drive drum 8 on which it is the end as well as the drive means 12 fixed and wound on rotation of the drive drum 18 simultaneously and at the same speed as the Antriebsmittei 12 ,
Fig. 2 zeigt eine schematische Seitenansicht der Antriebseinheit in axialer Richtung, wobei auch eine radiale Tiefe T der Aufhahmebereiche 6 f r die Zugmittel 8 erkennbar ist, die in dem dargestellten Beispiel etwa 25% des Radius (0,5 DA) des Antriebsbereichs 14 beträgt, allerdings auch größer oder kleiner gewählt sein kann, und beispielsweise bis zu 10%, 20%, 30%, 50% oder 75% des Radius des Antriebsbereichs 14 betragen kann. Der Basisdurchmesser d der Aufhahmebereiche 6 ist ebenfalls angegeben. 2 shows a schematic side view of the drive unit in the axial direction, whereby a radial depth T of the receiving regions 6 for the traction means 8 can be seen, which in the illustrated example is approximately 25% of the radius (0.5 DA) of the drive region 14, however, may also be larger or smaller, and for example up to 10%, 20%, 30%, 50% or 75% of the radius of the drive portion 14 may be. The base diameter d of the receiving areas 6 is also indicated.
