Abstract

The trolley has a vertical arm (2) with a roller running on a rail and a similar arm (20) running behind on the same rail and supporting below them a horizontal rod (3). At the front of the first arm, near the bottom is a U-shaped ear (8) projecting forwards. At the bottom of the second arm is an axle (71) which can be adjusted in height, with a coupling finger (72) which points to the rod in its neutral position. When the axle is lowered, a boss stops the rotation of the finger. The finger is used to attach the ear of the next trolley on the rail.

Description

Die Erfindung betrifft Trolleys zur Verwendung in Hängeförderanlagen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to trolleys for use in overhead conveyors according to the preamble of claim 1.

Hängeförderanlagen mit Trolleys werden hauptsächlich in der Bekleidungsindustrie eingesetzt. Die Förderanlage besitzt Tragschienen, auf der die Trolleys rollen. Der Antrieb erfolgt über eine endlos umlaufende Antriebskette, an die die Trolleys lösbar gekoppelt werden können.Overhead conveyors with trolleys are mainly used in the clothing industry. The conveyor system has mounting rails on which the trolleys roll. The drive takes place via an endless rotating drive chain to which the trolleys can be detachably coupled.

Die Trolleys selbst bestehen im wesentlichen aus einem vorderen und einem hinteren Laufwerk und einer unter den Laufwerken gelenkig befestigten Tragstange, an der die Fördergüter mittels Haken angehängt werden.The trolleys themselves consist essentially of a front and a rear drive and a support rod articulated under the drives, to which the goods are attached by means of hooks.

Die Laufwerke der meisten Trolleys sind darüber hinaus mit Kupplungsvorrichtungen ausgerüstet, die das Zusammenhängen mehrerer Trolleys zu einem Wagenzug ermöglichen. Die Kupplungseinrichtungen sind mit Steuerfingern ausgerüstet, so daß die Kupplungen über externe Steuernocken aktiviert und deaktiviert werden können.The drives of most trolleys are also equipped with coupling devices that allow several trolleys to be connected to form a wagon train. The coupling devices are equipped with control fingers so that the couplings can be activated and deactivated via external control cams.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine besonders einfache, leicht zu betätigende und gleichzeitig besonders betriebssichere Kupplung für Trolleys der eingangs genannten Art anzugeben.The present invention has for its object to provide a particularly simple, easy to operate and at the same time particularly reliable coupling for trolleys of the type mentioned.

Diese Aufgabe wird gelöst durch einen Trolley mit den Merkmalen gemäß Anspruch 1.This object is achieved by a trolley with the features according to claim 1.

Die erfindungsgemäße Kupplungsvorrichtung besteht aus nur wenigen Teilen, einer starren Öse am einen Laufwerk und einem an einer Achse pendelnd gelagerten Kupplungsfinger am anderen Laufwerk, wobei die die Laufrollen tragenden Rahmen U-förmig gebogen sind, um einerseits die Öse, andererseits die heb- und senkbare Achse jeweils beidseitig befestigen zu können. Die Laufwerke, die Öse und der Kupplungsfinger korrespondieren derart miteinander, daß die Öse beim Zusammenfahren zweier Trolleys als Zentrierung wirkt und den pendelnd gelagerten Kupplungsfinger anhebt, der anschließend in die Öse einfallt. Ist die Achse mit dem Kupplungsfinger abgesenkt, so können die Trolleys nicht mehr getrennt werden, da dann ein Anschlag am Laufwerksrahmen das freie Ende des Kupplungsfingers blockiert.The coupling device according to the invention consists of only a few parts, a rigid eyelet on one drive and a coupling finger mounted on an axle in an oscillating manner on the other drive to be able to fix the lifting and lowering axle on both sides. The drives, the eyelet and the coupling finger correspond to each other in such a way that when two trolleys move together, the eyelet acts as a centering device and lifts the oscillating coupling finger, which then falls into the eyelet. If the axle is lowered with the clutch finger, the trolleys can no longer be separated because a stop on the drive frame then blocks the free end of the clutch finger.

Das Anheben und Absenken der Achse mit dem Kupplungsfinger bewirken in bekannter Weise die Steuernocken in der Hängeförderanlage. Um nun die Achse in den beiden Endstellungen sicher halten zu können, ist gemäß einer vorteilhaften Weiterbildung der Erfindung eine federbelastete Kniehebelmechanik vorgesehen.The raising and lowering of the axle with the clutch finger effect the control cams in the overhead conveyor system in a known manner. In order to be able to hold the axis securely in the two end positions, a spring-loaded toggle lever mechanism is provided according to an advantageous development of the invention.

Erfindungsgemäß zeigt der Kupplungsfinger im Ruhezustand zum Tragarm hin. Dieser Ruhezustand des Kupplungsfingers läßt sich vorteilhafterweise zum einen durch eine Feder, zum anderen durch ein Gewicht fixieren. Zweck dieser Maßnahmen ist es, ein Verklemmen des Kupplungsfingers zu vermeiden, wenn die Achse aus ihrer angehobenen Position abgesenkt wird.According to the invention, the coupling finger points towards the support arm in the idle state. This idle state of the clutch finger can advantageously be fixed on the one hand by a spring and on the other hand by a weight. The purpose of these measures is to prevent the clutch finger from jamming when the axle is lowered from its raised position.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die Achse Teil einer Kurbel- oder Exzenterwelle. In diesem Fall erfolgt das Anheben und Absenken des Kupplungsfingers über eine Drehbewegung der Welle.According to a preferred embodiment of the invention, the axis is part of a crank or eccentric shaft. In this case, the clutch finger is raised and lowered by rotating the shaft.

Vorzugsweise ist an der Welle eine Kurbel befestigt, wobei die Kurbel außerhalb des Laufwerkrahmens sitzt. Der Kurbelzapfen wirkt als Steuerfinger und tritt gegebenenfalls in Wirkverbindung mit den in der Anlage verteilten Steuernocken, um die Kupplung zu aktivieren oder zu deaktivieren.A crank is preferably attached to the shaft, the crank being located outside the drive frame. The crank pin acts as a control finger and, if necessary, comes into operative connection with the control cams distributed in the system in order to activate or deactivate the clutch.

Gemäß einer Ausgestaltung der Erfindung ist der Drehwinkel der Welle begrenzt. Dies gilt insbesondere dann, wenn die Welle samt Kurbel mit Hilfe einer exzentrisch gelagerten Feder eine federbelastete Kniehebelmechanik bildet.According to one embodiment of the invention, the angle of rotation of the shaft is limited. This applies in particular when the shaft and crank form a spring-loaded toggle lever mechanism with the aid of an eccentrically mounted spring.

Fig. 1 zeigt eine Frontansicht eines ersten Laufwerks 2 eines Trolleys, geschnitten entlang der Linie I-I in Fig. 2. Man erkennt einen ersten Tragarm 1, an dem eine Tragstange 3 befestigt ist. Der Tragarm 1 ist mittels eines Drehgelenks 4 unter dem Laufwerk 2 montiert. Dieses besteht aus einem aus Blech gebogenen Rahmen 5. Das obere Ende des Rahmens 5 ist U-förmig gebogen und trägt eine Laufrolle 6, die auf einer Tragschiene 30 der Hängeförderanlage rollt. Die für den Antrieb der Trolleys verantwortliche, endlos umlaufende Förderkette und deren Kupplungseinrichtungen sind nicht dargestellt.1 shows a front view of a first drive 2 of a trolley, cut along the line I-I in FIG. 2. A first support arm 1 to which a support rod 3 is fastened can be seen. The support arm 1 is mounted under the drive 2 by means of a swivel joint 4. This consists of a sheet metal frame 5. The upper end of the frame 5 is bent in a U-shape and carries a roller 6 which rolls on a mounting rail 30 of the overhead conveyor system. The endlessly rotating conveyor chain responsible for driving the trolleys and their coupling devices are not shown.

Auch das untere Ende des Rahmens 5 ist als U-förmiges Ende 7 ausgebildet. Zwischen die U-Schenkel ist eine aus Draht gebogene Öse 8 waagerecht eingeschweißt.The lower end of the frame 5 is also designed as a U-shaped end 7. A wire-bent eyelet 8 is welded horizontally between the U-legs.

Fig. 2 zeigt den Trolley in Draufsicht, und zwar geschnitten entlang der Linie II-II in Fig. 1. Man erkennt, daß die Öse 8 über das Laufwerk 2 übersteht. Sie wirkt gleichzeitig als Zentrierung, wenn zwei Trolleys zusammengekuppelt werden, was noch anhand der Fig. 3 näher beschrieben werden soll.Fig. 2 shows the trolley in plan view, namely cut along the line II-II in Fig. 1. It can be seen that the eyelet 8 survives drive 2. It also acts as a centering when two trolleys are coupled together, which will be described in more detail with reference to FIG. 3.

Fig. 2 zeigt auch das zweite Laufwerk 20 am anderen Ende der Tragstange 3. Dessen Rahmen 5 ist in gleicher Weise oben wie unten U-förmig gebogen und trägt oben wiederum eine Laufrolle (nicht dargestellt).Fig. 2 also shows the second carriage 20 at the other end of the support rod 3. Its frame 5 is bent in a U-shaped manner in the same manner as above and carries a roller (not shown) at the top.

Im unteren, U-förmig ausgebildeten Ende 70 des zweiten Laufwerks 20 ist eine Querachse 71 gelagert, auf der ein Kupplungsfinger 72 frei drehbar gelagert ist. Eine Feder 73 sorgt dafür, daß der Kupplungsfinger 72 im Ruhezustand zur Tragstange 3 hin zeigt.In the lower, U-shaped end 70 of the second drive 20, a transverse axis 71 is mounted, on which a coupling finger 72 is freely rotatable. A spring 73 ensures that the coupling finger 72 points towards the support rod 3 in the idle state.

Im vorliegenden Ausführungsbeispiel ist die Achse 71 Teil einer Kurbel- bzw. Exzenterwelle 71', die an ihrem einen Ende außerhalb des Rahmens 5 eine Kurbel 74, 75 trägt. Sind in der Hängeförderanlage Steuernocken (nicht dargestellt) vorgesehen, tritt der Kurbelzapfen 75 in Wirkverbindung zu diesen, wodurch die Kupplung aktiviert und deaktiviert wird. Dies geschieht dadurch, daß der Kurbelzapfen 75 entweder angehoben oder abgesenkt wird, was sich über den Kurbelhebel 74 auf die Exzenterwelle 71' überträgt. Sobald sich die Exzenterwelle 71' dreht, wird die exzentrisch angeordnete Achse 71, auf der der Kupplungsfinger 72 gelagert ist, angehoben oder abgesenkt.In the present exemplary embodiment, the axis 71 is part of a crankshaft or eccentric shaft 71 'which carries a crank 74, 75 at one end outside the frame 5. If control cams (not shown) are provided in the overhead conveyor system, the crank pin 75 is operatively connected to them, whereby the clutch is activated and deactivated. This is done in that the crank pin 75 is either raised or lowered, which is transmitted via the crank lever 74 to the eccentric shaft 71 '. As soon as the eccentric shaft 71 'rotates, the eccentrically arranged axis 71, on which the clutch finger 72 is mounted, is raised or lowered.

Um die Achse 71 mit dem Kupplungsfinger 72 in ihren beiden Endstellungen sicher fixieren zu können, ist die Kurbel 74, 75 der Exzenterwelle 71' mit Hilfe einer Feder 76, die an einen exzentrisch angeordneten Haltezapfen 77 einerseits und an dem Kurbelzapfen 75 andererseits befestigt ist, als federbelastete Kniehebelmechanik ausgebildet.In order to be able to securely fix the axis 71 with the coupling finger 72 in its two end positions, the crank 74, 75 of the eccentric shaft 71 'is by means of a spring 76, which is fastened to an eccentrically arranged holding pin 77 on the one hand and to the crank pin 75 on the other hand, designed as a spring-loaded toggle mechanism.

Fig. 3 schließlich zeigt zwei gekoppelte Trolleys. Die Öse 8 des rechten Trolleys ist in das Laufwerk 20 des linken Trolleys eingefahren, der Kupplungsfinger 72 ist in die Öse 8 eingefallen.3 finally shows two coupled trolleys. The eyelet 8 of the right trolley has moved into the drive 20 of the left trolley, the coupling finger 72 has fallen into the eyelet 8.

Fig. 3 zeigt die Achse 71 in ihrer abgesenkten Position. Die Länge des Kupplungsfingers 72 ist derart abgestimmt, daß er durch einen Anschlag 78, hier den Boden des Laufwerks 20 selbst, blockiert wird. Die beiden Trolleys sind fest gekoppelt.Fig. 3 shows the axis 71 in its lowered position. The length of the coupling finger 72 is adjusted such that it is blocked by a stop 78, here the bottom of the drive 20 itself. The two trolleys are firmly coupled.

Zum Lösen der Kupplung wird die Kurbel 74, 75 nach unten geschwenkt, worauf sich die Exzenterwelle 71' dreht und die Achse 71 angehoben wird. Die Blockierung des Mitnehmerfingers 72 durch den Anschlag 78 wird dabei aufgehoben und die Öse 8 kann sich lösen.To release the clutch, the crank 74, 75 is pivoted downward, whereupon the eccentric shaft 71 'rotates and the axis 71 is raised. The blocking of the driving finger 72 by the stop 78 is released and the eyelet 8 can come loose.

Das Ausführungsbeispiel der Fig. 3 zeigt, daß die Fixierung des Mitnehmerfingers 72 in der Ruhelage auch mit Hilfe eines Gewichts 73' sichergestellt werden kann, das den Schwerpunkt entsprechend verlagert.The embodiment of FIG. 3 shows that the fixing of the driver finger 72 in the rest position can also be ensured with the aid of a weight 73 'which shifts the center of gravity accordingly.

Wie die Ausführungsbeispiele erkennen lassen, besitzt die neue Kupplung nur noch wenige Einzelteile und geringe äußere Abmessungen, so daß insbesondere Kollisionen mit Komponenten der Hängeförderanlage einerseits und den Fördergütern andererseits praktisch ausgeschlossen sind. Koppeln und Entkoppeln erfolgen praktisch kräftefrei. Auf den Kupplungsfinger wirkende Zugkräfte führen zu einer Selbstverriegelung; trotzdem ist das Entkoppeln auch unter Last problemlos möglich.As can be seen from the exemplary embodiments, the new coupling has only a few individual parts and small external dimensions, so that collisions with components of the overhead conveyor system on the one hand and the conveyed goods on the other hand are practically impossible. Coupling and decoupling are practically free of forces. Tractive forces acting on the clutch finger lead to self-locking; nevertheless, decoupling is possible even under load.
