Description

Die Erfindung betrifft eine Vorrichtung zur Aufnahme und/oder zum Bewickeln einer Kabeltrommel, mit einem portalartigen, verfahrbaren Rahmen, an dem zwei mit Ein-greifelementen zur Aufnahme der Kabeltrommel versehene, über jeweils ein Hubwerk höhenverstellbare Tragarme gehalten sind.The invention relates to a device for receiving and / or winding a cable drum, with a portal-like, movable frame, on which two are provided with engaging elements for receiving the cable drum, each of which is height-adjustable via a lifting mechanism.

Bei einer aus der WO 90/15771 bekannt gewordenen Vorrichtung dieser Art bilden Tragarm und Hubwerk eine Einheit, die am Rahmen mittels eines Federelementes abgestützt ist.In a device of this type which has become known from WO 90/15771, the support arm and lifting mechanism form a unit which is supported on the frame by means of a spring element.

Hiedurch wird gleichzeitig eine flexible Bewegung des Tragarms in seiner axialen Richtung und einer Schwenkbewegung in einer Ebene senkrecht zur Spulenachse erreicht, jedoch muß hiezu die gesamte Masse der Tragarm/Hubwerk-Einheit gegen die Kraft der das gesamte System abstützenden Feder bewegt werden, was zufolge der großen Trägheit eines solchen Systems schwierig, und nur in groben Schritten möglich ist. Darüber hinaus erlaubt diese vorbekannte Einrichtung keine Feineinstellung zusätzlich zum eigentlichen Hubwerksantrieb.As a result, a flexible movement of the support arm in its axial direction and a pivoting movement in a plane perpendicular to the coil axis is achieved at the same time, but for this purpose the entire mass of the support arm / lifting unit must be moved against the force of the spring supporting the entire system, which according to the great inertia of such a system difficult, and is only possible in rough steps. In addition, this known device does not allow fine adjustment in addition to the actual hoist drive.

Aufgabe der Erfindung ist es daher, eine Vorrichtung zu schaffen, welche die oben genannten Nachteile vermeidet, und ein einfaches Aufnehmen einer Trommel beliebigen Durchmessers rasch und ohne großen konstruktiven Aufwand ermöglicht. Ferner ist es Aufgabe der Erfindung, eine in ihrer Bewegbarkeit leichtgängige Vorrichtung zu schaffen, die eine große Schwenkbewegung der Tragarm/Hubwerk-Einheit erlaubt.The object of the invention is therefore to provide a device which avoids the disadvantages mentioned above and enables a drum of any diameter to be picked up quickly and without great design effort. Furthermore, it is an object of the invention to provide a device which is easy to move and which permits a large pivoting movement of the support arm / lifting unit.

Die Erfindung löst diese Aufgabe bei einer Vorrichtung der eingangs genannten Art dadurch, daß jedes Hubwerk am Rahmen pendelnd angeordnet ist, wobei der Tragarm selbst an dem ihm zugeordneten Hubwerk mittels Federelementen in einer vorwählbaren Lage federnd aufgehängt ist. Hiedurch sind die Bewegungen des Tragarmes in Richtung seiner Längsachse (Federbewegung) und in der zur Spulenachse senkrechten Ebene (Pendelbewegung) unabhängig voneinander möglich. Dadurch, daß der Tragarm selbst federnd aufgehängt ist, sind für seine Bewegung nur mehr kleinere Massen zu bewegen, sodaß die Bewegung insgesamt leichtgängiger wird. Andererseits kann zufolge der pendelnden Aufhängung des Hubwerkes am Rahmen ohne weiteres eine große Schwenkbewegung des Hubwerkes erreicht werden.The invention solves this problem in a device of the type mentioned in that each hoist is arranged in a pendulum manner on the frame, the support arm itself being resiliently suspended in a preselectable position on the hoist assigned to it by means of spring elements. In this way, the movements of the support arm in the direction of its longitudinal axis (spring movement) and in the plane perpendicular to the coil axis (pendulum movement) are possible independently of one another. Because the support arm itself is resiliently suspended, only smaller masses are to be moved for its movement, so that the movement becomes smoother overall. On the other hand, due to the oscillating suspension of the hoist on the frame, a large swiveling movement of the hoist can easily be achieved.

In Weiterbildung der Erfindung wird zweckmäßig so vorgegangen, daß die Federelemente jeweils zweiteilig ausgebildet sind, welche Teile in entgegengesetzten Richtungen an dem Hubwerk angreifen. Hiedurch ist eine schwebende Aufhängung der Tragarme möglich, die es ermöglicht, die neutrale Lage dieser schwebenden Aufhängung nicht nur genau einzustellen, sondern auch zu überwachen, und gegebenenfalls - bedingt durch Ermüdungserscheinungen der Federelemente - nachzujustieren, dies alles unabhängig von den Maßnahmen zur Erreichung der Pendelbewegung.In a further development of the invention, the procedure is expediently such that the spring elements are each formed in two parts, which parts act on the lifting mechanism in opposite directions. This enables a floating suspension of the support arms, which makes it possible not only to precisely adjust the neutral position of this floating suspension, but also to monitor and, if necessary - readjust due to fatigue of the spring elements - all this regardless of the measures to achieve the pendulum movement.

Bei einer Vorrichtung, bei welcher das Hubwerk einen Hubwerksmotor, eine Hubwerksspindel und eine Hubwerksmutter umfaßt, können nach einer anderen Weiterbildung der Erfindung die den Tragarm tragenden Federelemente an der Hubwerksmutter und dem Tragarm fixiert sein.In a device in which the hoist comprises a hoist motor, a hoist spindle and a hoist nut, according to another development of the invention the spring elements carrying the support arm can be fixed to the hoist nut and the support arm.

Die Höhenverstellung erfolgt also derart, daß ein vom Hubwerk getriebener Spindelantrieb mit einer Hubwerksmutter zusammenwirkt und zufolge der Drehbewegung der Spindel eine Auf- bzw. Abwärtsbewegung der Tragarme bewirkt.The height adjustment is carried out in such a way that a spindle drive driven by the lifting mechanism interacts with a lifting mechanism nut and, due to the rotary movement of the spindle, causes the support arms to move upwards or downwards.

Nach einer anderen Ausbildung der Erfindung ist die Hubwerksmutter sowie der Tragarm von zwei die Federelemente aufnehmenden Bolzen in Pendelrichtung durchsetzt, wobei die maximale Federbewegung durch eine obere und eine untere Anschlagkante für die Bolzen in den Tragarmen begrenzt ist.According to another embodiment of the invention, the lifting mechanism nut and the support arm are penetrated by two bolts receiving the spring elements in the pendulum direction, the maximum spring movement being limited by an upper and a lower stop edge for the bolts in the support arms.

Dadurch wird vermieden, daß die Haltearme größere Bewegungen in ihrer Längsrichtung ausführen.This prevents the holding arms from making larger movements in their longitudinal direction.

Vorteilhafterweise ist nach einer Weiterbildung der Erfindung auch eine Einrichtung zur Einstellung der Tragarme in einer Mittellage zwischen den Anschlagkanten vorgesehen.Advantageously, according to a development of the invention, a device for adjusting the support arms in a central position between the stop edges is also provided.

Nach einer bevorzugten Ausführungsform der Erfindung weisen die Federelemente jeweils eine Haltefeder und eine Einstellfeder auf, die in entgegengesetzten Richtungen an den Bolzen angreifen.According to a preferred embodiment of the invention, the spring elements each have a retaining spring and an adjusting spring which engage the bolt in opposite directions.

Die Mittellage (neutrale Lage) kann vor Arbeitsbeginn händisch eingestellt werden, wobei die Federarme nach Absetzen der Trommel immer wieder in die Mittellage zurückkehren, wodurch auch ein Wechsel der Trommeldurchmesser ohne Probleme bewältigbar ist.The middle position (neutral position) can be adjusted manually before starting work, with the spring arms always returning to the middle position after the drum has been set down, which means that changing the drum diameter is also manageable without any problems.

Um ein rechtzeitiges Abschalten der Bewegung der Tragarme in einer Längsrichtung zu gewährleisten, ist nach einer Weiterbildung der Erfindung eine Vorrichtung zur Überwachung der Mittellage zwischen oberer und unterer Anschlagkante vorgesehen.In order to ensure timely switching off of the movement of the support arms in a longitudinal direction, a device for monitoring the central position between the upper and lower stop edge is provided according to a development of the invention.

Die Federkraft der Haltefedern liegt idealerweise über der Gewichtskraft des Tragarmes und der Pinolenwelle.The spring force of the retaining springs is ideally above the weight of the support arm and the quill shaft.

Die Vorrichtung zur Überwachung der Mittellage kann nach einer möglichen Weiterbildung der Erfindung ein in diesem Bereich angeordneter Näherungsschalter sein, der vorzugsweise mit einer Steuereinheit verbunden ist, welche bei Erreichen der Mittellage nach Absenken der Trommel das Hubwerk abstellt.According to a possible development of the invention, the device for monitoring the central position can be a proximity switch arranged in this area, which is preferably is connected to a control unit which, when the central position is reached after the drum has been lowered, switches off the lifting mechanism.

Nach einer anderen Variante der erfindungsgemäßen Vorrichtung kann die Vorrichtung zur Überwachung der Mittellage auch ein mit einem Endschalter für den Hubantrieb zusammenwirkendes Zeitrelais sein, wobei der Endschalter vorzugsweise im Bereich des Hubwerksmotors angeordnet ist.According to another variant of the device according to the invention, the device for monitoring the central position can also be a time relay which interacts with a limit switch for the lifting drive, the limit switch preferably being arranged in the region of the hoist motor.

Die Überwachung der Mittellage ist insbesondere bei Trommelwechsel wichtig. Erst wenn der Näherungsschalter die Mittellage kontrolliert und festgestellt hat, kann das Hubwerk abgestellt und die Vorrichtung geöffnet werden, um die Trommel zu entnehmen.Monitoring the central position is particularly important when changing the drum. Only when the proximity switch has checked and determined the central position can the lifting mechanism be switched off and the device opened to remove the drum.

Bei Verwendung eines Zeitrelais fährt das Hubwerk nach dem Aufsetzen der Trommel bis zum unteren Anschlag und der Hubantrieb wird anschließend mit dem Lagerbolzen nach oben ausgehoben, worauf es automatisch angeschaltet wird. Das Zeitrelais steuert das Hubwerk anschließend derart, daß der Lagerbolzen wieder in seine ursprüngliche Lage gelangt und die Mittellage erreicht wird. Dies ist insbesondere deshalb möglich, da der mögliche maximale Weg der Bolzen zwischen den Anschlägen und die von der Spindel für das Hochfahren notwendige Zeit dem Relais bekannt ist.If a time relay is used, the lifting mechanism moves to the lower stop after the drum has been put on and the lifting drive is then lifted up with the bearing pin, after which it is automatically switched on. The timing relay then controls the lifting mechanism in such a way that the bearing pin returns to its original position and the middle position is reached. This is possible in particular because the possible maximum path of the bolts between the stops and the time required for the spindle to start up is known to the relay.

Idealerweise sind die Anschlagkanten durch in den Haltearmen vorgesehene Längsschlitze gebildet, welche von den Bolzen durchsetzt sind.The stop edges are ideally formed by longitudinal slots provided in the holding arms, through which the bolts pass.

Beim Anheben der Trommel zwischen jedem Tragarm und den in der Spindelmutter angeordneten Bolzen kommen diese Teile in Anlage.When the drum is lifted between each support arm and the bolts arranged in the spindle nut, these parts come into contact.

Die Erfindung wird nun im folgenden an Ausführungsbeispielen unter Zuhilfenahme der angeschlossenen Zeichnungen näher beschrieben.The invention will now be described in more detail below using exemplary embodiments with the aid of the attached drawings.

In einem Rahmen 1 sind zwei voneinander beabstandete Tragarme 2, 2' über eine Hubwerkspindel 5a bewegbar angeordnet. Der Antrieb erfolgt über den Hubwerksmotor 3, der die mit der Hubwerksmutter 5b verbundene Hubwerksspindel 5a antreibt. Durch die Rotation der Hubwerksspindel erfolgt eine Auf- bzw. Abwärtsbewegung des Tragarmes 2 bzw. 2' (Fig.1).In a frame 1, two spaced-apart support arms 2, 2 'are arranged such that they can move via a lifting spindle 5a. The drive takes place via the hoist motor 3, which drives the hoist spindle 5a connected to the hoist nut 5b. The rotation of the hoist spindle causes the support arm 2 or 2 'to move up or down (FIG. 1).

Fig.2 zeigt die Bewegung des Tragarmes 2 in drei unterschiedlichen Stellungen, wobei insbesondere auch die Bewegung der Hubwerksmutter 5b zusammen mit dem Tragarm ersichtlich ist.2 shows the movement of the support arm 2 in three different positions, wherein in particular the movement of the lifting nut 5b together with the support arm can also be seen.

Jeder Tragarm bildet mit einer eine Aufsteckhülse 14 zum Eingreifen in die entsprechende Öffnung der in Fig.1 strichliert dargestellten Trommel 15 tragenden Pinolenwelle 13 eine starre Einheit und ist demzufolge gegenüber den in diesem Bereich auf die Vorrichtung einwirkenden relativ großen Kräfte unempfindlich.Each support arm forms a rigid unit with a push-on sleeve 14 for engaging in the corresponding opening of the barrel 15 shown in dashed lines in FIG. 1 and is consequently insensitive to the relatively large forces acting on the device in this area.

Fig.3 zeigt eine detaillierte Darstellung des Systems. Das Hubwerk ist im Bereich des Hubwerksmotors 3 am Rahmen 1 um den Lagerbolzen 4 pendelnd angeordnet. Der Tragarm 2 ist über die Haltefedern 7 federnd an durch die Hubwerksmutter 5b geführte Bolzen 6 aufgehängt.3 shows a detailed illustration of the system. The hoist is arranged in the area of the hoist motor 3 on the frame 1 swinging around the bearing pin 4. The support arm 2 is resiliently suspended by the retaining springs 7 on bolts 6 guided by the lifting nut 5b.

Die Federkraft der Haltefedern 7 ist etwas größer als die Gewichtskraft des Tragarmes 2 und der Pinolenwelle zusammen, weshalb diese Kombination nach oben gezogen wird.The spring force of the retaining springs 7 is slightly greater than the weight of the support arm 2 and the quill shaft together, which is why this combination is pulled upwards.

Wie im einzelnen Fig. 4a und Fig. 4b zeigen, sind durch die Hubwerksmutter 5b zu beiden Seiten der Hubwerksspindel zwei Bolzen 6 in Pendelrichtung gesteckt. Diese Bolzen 6 tragen Haltebleche 16,16', in welche die Haltefedern mit dem einen Ende eingehängt sind, wohingegen das andere Ende mit dem Tragarm 2 fest verbunden ist.As shown in FIGS. 4a and 4b in detail, two bolts 6 are inserted in the pendulum direction through the lifting nut 5b on both sides of the lifting spindle. These bolts 6 carry holding plates 16, 16 ', in which the holding springs are suspended at one end, whereas the other end is firmly connected to the support arm 2.

Die Bolzen 6 treten aus der Hubwerksmutter 5b durch Längsschlitze 10 des Tragarms 2, welche gleichzeitig eine Begrenzung für die Auf- Abwärtsbewegung und durch eine obere 21 und eine untere 22 Anschlagkante bilden.The bolts 6 emerge from the hoist nut 5b through longitudinal slots 10 of the support arm 2, which simultaneously form a limitation for the upward and downward movement and through an upper 21 and a lower 22 stop edge.

Es sind weiters Einstellfedern 8, welche den Haltefedern 7 entgegenwirken und ebenfalls in den Halteblechen 16,16' eingehängt sind, vorgesehen, über welche die Mittellage in den Längsschlitzen 10 genau eingestellt werden kann, wobei zufolge der Systemanordnung beim Schließen eine Selbstführung eintritt.There are also adjusting springs 8, which counteract the retaining springs 7 and are likewise suspended in the retaining plates 16, 16 ', by means of which the central position in the longitudinal slots 10 can be precisely adjusted, and according to the system arrangement, self-guidance occurs when closing.

Mit den Doppelmutter-Schrauben 23 kann die Einstellung der Tragarme 2 in der Mittellage zwischen den Anschlagkanten 21,22 vorgenommen werden.With the double nut screws 23, the setting of the support arms 2 can be carried out in the middle position between the stop edges 21, 22.

Schräg eingerollte, unrunde oder auch beschädigte Trommeln können mit den angeschrägten Aufsteckhülsen 14 leicht aufgenommen werden.Diagonally rolled, out-of-round or damaged drums can easily be picked up with the beveled push-on sleeves 14.

Das Anheben einer Trommel in die Wickelposition erfolgt nun derart, daß das um den Lagerbolzen 4 pendelnde und an der Hubwerksmutter 5b federnd aufgehängte System über den Hubwerksmotor 3 soweit bewegt wird, daß die Bolzen 6 am oberen Anschlag der Längsschlitze 10 anliegen, in der höchsten Hubstellung erfolgt eine Fixierung insbesondere der Pendelbewegung über Gleitelemente 11 in einer entsprechenden Ausnehmung 24 im Rahmen 1.The lifting of a drum into the winding position is now carried out in such a way that the system oscillating around the bearing pin 4 and resiliently suspended on the lifting nut 5b is moved so far via the lifting motor 3 that the pins 6 rest against the upper stop of the longitudinal slots 10, in the highest lifting position the pendulum movement is fixed in particular via sliding elements 11 in a corresponding recess 24 in the frame 1.

Der Bolzenweg beträgt vorzugsweise 15 mm.The bolt path is preferably 15 mm.

Beim Absenken der Trommel über die von den Spindelmuttern 5b angetriebenen Tragarme 2 fährt das Hubwerk nach Erreichen des Bodens durch die Trommel solange nach unten bis die Bolzen in den Längsschlitzen die eingestellte Mittellage wieder erreichen.When the drum is lowered via the support arms 2 driven by the spindle nuts 5b, the lifting mechanism, after reaching the floor, moves downward through the drum until the bolts in the longitudinal slots reach the set central position again.

Diese Mittellage wird über einen am Tragarm angeordneten, auf die Mittellage zentrierten Näherungsschalter 9 festgestellt, der über eine nicht dargestellte Steuereinheit das Hubwerk automatisch abschaltet.This central position is determined via a proximity switch 9 which is arranged on the support arm and centered on the central position and which automatically switches off the lifting mechanism via a control unit (not shown).

Dadurch stehen die beiden Tragarme wieder auf gleicher Höhe, sind aber weiters vorteilhafterweise schwebend aufgehängt und lassen eine Federbewegung nach oben und unten zu.As a result, the two support arms are again at the same height, but are also advantageously suspended in a floating manner and allow a spring movement up and down.

Nach dem Abschalten des Hubwerkes erfolgt ein automatisches Öffnen der Vorrichtung.After the lifting gear has been switched off, the device opens automatically.

Die Überwachung der Mittellage ist insbesondere bei Trommelwechsel wichtigMonitoring the central position is particularly important when changing the drum

Eine weitere Möglichkeit zur Überwachung der Mittellage ist in Fig.5 dargestellt.Another possibility for monitoring the central position is shown in Fig. 5.

Anstelle des Näherungsschalters 9 wird in dieser Variante über einen im Bereich des Pendellagers 4 angeordneten Endschalter 12, der mit einem Zeitrelais zusammenwirkt, die Mittellage überwacht und fixiert.Instead of the proximity switch 9, the middle position is monitored and fixed in this variant via a limit switch 12 which is arranged in the region of the self-aligning bearing 4 and which interacts with a time relay.

Beim Absenken der Trommel fährt das Hubwerk nach Bodenkontakt der Trommel solange nach unten, bis die Bolzen 6 an den Unterkanten 22 der Längsschlitze 10 anliegen. Der Hubantrieb 3 wird mit den Lagerbolzen 4 nach oben angehoben, wobei die Lagerbolzen in den sie aufnehmenden Schlitzen nach oben wandern und der Endschalter das Hubwerk abschaltet.When the drum is lowered, the lifting mechanism moves downward after the drum comes into contact with the ground until the bolts 6 rest on the lower edges 22 of the longitudinal slots 10. The lifting drive 3 is lifted up with the bearing bolts 4, the bearing bolts moving upward in the slots receiving them and the limit switch switching off the lifting mechanism.

Anschließend erfolgt - gesteuert vom Zeitrelais - wieder ein Absenken um den in die Mittellage führenden Weg, wobei die für das Zeitrelais wesentlichen Daten der Bolzenweg, welcher 15 mm beträgt, und die Zeit, welche die Spindel zum Ausheben des Lagerbolzens benötigte, sind.Then - controlled by the time relay - there is again a lowering by the path leading to the central position, whereby the data essential for the time relay are the pin travel, which is 15 mm, and the time that the spindle needed to lift the bearing pin.

Auf diese Art wird der Lagerbolzen 4 wieder in seine ursprüngliche Lage zurückversetzt und eine Mittellage in den Längsschlitzen 10 erreicht.In this way, the bearing pin 4 is returned to its original position and a central position in the longitudinal slots 10 is reached.

Durch das Erreichen der Mittellage sind auch unabhängig von ihrer vorangegangenen Stellung die beiden Tragarme auf gleicher Höhe und schwebend aufgehängt, wodurch sowohl die Pendel- als auch die Federbewegung wieder gegeben sind, wobei in diesem entlasteten Zustand die beim Anheben und Absenken gegebene Verbindung Tragarm-Hubspindel durch die federnde Aufhängung aufgehoben ist.By reaching the middle position, regardless of their previous position, the two support arms are suspended at the same height and floating, whereby both the pendulum and the spring movement are given again, whereby in this relieved state the connection between the support arm and the lifting spindle is given is suspended by the resilient suspension.

Ein Aufnehmen einer neuen Trommel kann nun vorgenommen werden.A new drum can now be recorded.

Die Fig.6a,6b zeigen die Vorrichtung in einer detaillierteren Darstellung.6a, 6b show the device in a more detailed representation.

Ein T-förmiges Traggestell 20, 20' trägt den die Tragarme 2, 2' aufnehmenden Rahmen 1, 1'.A T-shaped support frame 20, 20 'carries the frame 1, 1' receiving the support arms 2, 2 '.

Die Verstellung der Portalbreite der Vorrichtung erfolgt über eine Spindel 19 und einen Fahrmotor 17.The portal width of the device is adjusted via a spindle 19 and a drive motor 17.

Demgemäß werden beim Öffnen der Vorrichtung die Spindel 19 und der Motor 17 gegenläufig verfahren; diese Bewegungen können gleichzeitig oder aufeinanderfolgend vor sich gehen.Accordingly, the spindle 19 and the motor 17 are moved in opposite directions when the device is opened; these movements can take place simultaneously or in succession.

Um eine Einstellung für ein automatisches Wickeln vornehmen zu können, ist ein durch eine schräg gestellte Wippe geführtes Reibrad 18 vorgesehen, welches an die Trommel 15 angepreßt wird. Bei Erreichen der Trommel 15 wird die Wippe mit dem Reibrad 18 durch einen nicht dargestellten Luftzylinder an die Trommel 15 angedrückt.In order to be able to make an adjustment for automatic winding, a friction wheel 18, which is guided by an inclined rocker, is provided and is pressed against the drum 15. When the drum 15 is reached, the rocker with the friction wheel 18 is pressed against the drum 15 by an air cylinder (not shown).
