Abstract

A drive element for rail-guided load carriers of an overhead conveyor system in which the driver, which is mounted on the drive element via a hole, has a horizontal groove which extends outward from the hole. Too high a horizontal force acting on the driver causes the drive to be pulled off of the pin. Thus, the drive element which is continuously driven via a drive chain can travel past a conveyor carriage which is blocked in the direction of conveyance without the drive element or the conveyor carriage being destroyed. In order to prevent a driver that has been pulled off of the pin from doing any damage, it is secured via a wire bow which is inserted into a continuous hole provided on the driver. If the overhead conveyor system is developed with branches and a pusher is arranged on the conveyor chain behind each conveyor carriage for pushing the conveyor carriage onto a branch, the pusher claw can be developed in the same way as the driver.

Description

Die Erfindung betrifft das Antriebselement für die Lastträger einer Hängeförderanlage nach dem Oberbegriff des Anspruchs 1.The invention relates to the drive element for the load carriers of a overhead conveyor system according to the preamble of claim 1.

Insbesondere in der Bekleidungsindustrie werden die auf Kleiderbügel hängenden Kleidungsstücke zum Zwecke des Kommissionierens oder des Abtransportes in die Tragstange der einspurigen Förderwagen, sogenannte Trolleys, einer Hängeförderanlage eingehängt. Die auf Schienen laufenden Trolleys werden über jeweils auf die vordere Laufrolle einwirkenden Mitnehmer, die an einem Antriebselement ausgebildet sind, das wiederum an der oberhalb der Laufschiene angeordneten Antriebskette befestigt ist, geschoben.
Damit ein Trolley sicher transportiert werden kann, muß der Mitnehmer entgegen der Transportrichtung starr sein. Um jedoch auch einen Trolley passieren zu können, ist er in Transportrichtung schwenkbar und kann damit über die Rollen der Trolleys hinweggeführt werden, wenn ein Trolley nicht zu transportieren sein sollte. Ein solches Antriebselement ist beispielsweise aus der CH-A-457 260 bekannt.In the clothing industry in particular, the items of clothing hanging on hangers are hung in the suspension bar of the single-track trolleys, a trolley conveyor, for the purpose of picking or transporting them away. The trolleys running on rails are pushed over drivers acting on the front roller, which are formed on a drive element, which in turn is fastened to the drive chain arranged above the rail.
So that a trolley can be transported safely, the driver must be rigid against the direction of transport. However, in order to be able to pass through a trolley, it can be swiveled in the direction of transport and can thus be guided over the roles of the trolleys if a trolley is not to be transported. Such a drive element is known for example from CH-A-457 260.

Bei Förderanlagen aus dem Hause der Anmelderin ist es bekannt, den aus Kunststoff ausgebildeten Mitnehmer mittels eines Bolzens, der horizontal und außermittig durch ein Ende des Mitnehmers hindurchgesteckt wird, an dem Antriebselement zu befestigen. Durch diese nicht symmetrisch angeordnete Schwenkachse des Mitnehmers, wird die nur in eine Richtung zulässige Schwenkbarkeit erzielt.In conveyor systems from the applicant's house, it is known to fasten the driver made of plastic to the drive element by means of a bolt which is inserted horizontally and off-center through one end of the driver. This pivot axis of the driver, which is not arranged symmetrically, achieves the pivotability which is only permissible in one direction.

Wenn ein Trolley im Förderstrang unbeabsichtigt an der Weiterfahrt gehindert wird, weil er beispielsweise auf ein Hindernis stößt oder die hintere Laufrolle irrtümlich an einer Weiche ausgeleist wurde, während die vordere Laufrolle weiterhin im Förderstrang verbleibt, werden - da die Antriebskette stetig umläuft - entweder das Antriebselement, der Mitnehmer oder sogar die gesamte Förderanlage unweigerlich zerstört.If a trolley in the conveyor belt is inadvertently prevented from moving on, for example because it encounters an obstacle or the rear roller was mistakenly moved out of the way on a switch while the front roller remains in the conveyor belt, then - since the drive chain rotates continuously - either the drive element , the driver or even the entire conveyor system inevitably destroyed.

Der Erfindung liegt die Aufgabe zugrunde, das Antriebselement so fortzubilden, daß ein irreversibler Schaden für den Fall eines für den Förderwagen blockierten Transportweges ausgeschlossen ist.The invention has for its object to develop the drive element so that irreversible damage is excluded in the event of a blocked transport route for the tram.

Die Lösung der Aufgabe erfolgt bei einem gattungsgemäßen Antriebselement durch die kennzeichnenden Merkmale des Anspruchs 1.The problem is solved in a generic drive element by the characterizing features of claim 1.

Durch die an dem hinteren Ende des Mitnehmers parallel zu der Bohrung und bis in diese hineinreichende Nut wird erreicht, daß der Mitnehmer einer starken auf ihn einwirkenden Kraft entgegen der Förderrichtung ausweichen kann, in dem er von dem Bolzen heruntergedrückt wird. Das Antriebselement kann dann ungehindert über den blockierten Trolley hinwegfahren.Due to the fact that at the rear end of the driver parallel to the bore and into this groove, it is achieved that the driver can avoid a strong force acting on it against the conveying direction, in which it is pressed down by the bolt. The drive element can then move freely over the blocked trolley.

Durch die Ausgestaltung nach Anspruch 2 wird erreicht, daß der Drehpunkt zum Aushebeln des Mitnehmers aus der Bohrungsachse herausverlegt wird.The configuration according to claim 2 ensures that the fulcrum for levering out the driver is moved out of the bore axis.

Durch den als Sicherung dienenden Drahtbügel nach Anspruch 3 ist sichergestellt, daß ein herausfliegender Mitnehmer keinen Schaden in der Umgebung anrichten kann, sondern am Antriebselement festgehalten wird.The serving as a fuse wire bracket according to claim 3 ensures that a flying driver can not cause damage in the area, but is held on the drive element.

Anhand einer Zeichnung soll die Erfindung nachfolgend näher erläutert werden.The invention will be explained in more detail below with the aid of a drawing.

Die Förderwagen 1 bestehen im wesentlichen aus der U-förmig gebogenen Tragstange 16, die an ihren beiden Enden drehbar in Laufrollenträgern 17 gelagert ist. Jeder Laufrollenträger 17 trägt die Achse 14 der Laufrolle 13. Die Laufrolle 13 umgreifend ist eine Stoßkappe 15 vorgesehen, auf die der vorzugsweise aus Kunststoff gefertigte Mitnehmer 2 des Antriebselements 7 einwirkt. Laufrollenträger 17, Laufrolle 13 und Stoßkappe 15 sind für das vordere und hintere Ende des Trolleys identisch ausgebildet und in der Zeichnung deshalb mit denselben Positionsziffern versehen.The trolleys 1 essentially consist of the U-shaped support rod 16, which is rotatably supported at both ends in roller carriers 17. Each roller carrier 17 carries the axis 14 of the roller 13. The roller 13 encompasses a bumper cap 15, on which the driver 2 of the drive element 7, which is preferably made of plastic, acts. Roller carrier 17, roller 13 and butt cap 15 are of identical design for the front and rear ends of the trolley and are therefore provided with the same item numbers in the drawing.

In die Tragstange 16 der Förderwagen 1 werden beispielsweise auf Kleiderbügeln hängende Kleidungsstücke eingehängt, und von der Produktionstelle in den Lagerbereich transportiert.Garments hanging on hangers, for example, are hung in the support rod 16 of the trolley 1 and transported from the production site to the storage area.

Der in Fig. 3 schematisch dargestellte Hängeförderer besteht im wesentlichen aus dem Kettenkanal 6 und der ein nicht näher dargestelltes Profil aufweisenden Laufschiene 4, auf der als Lastgehänge ausgebildete Förderwagen 1 - sogenannte Trolleys - laufen. In dem Kettenkanal 6 ist eine raumgelenkige Antriebskette 5, die durch einen nicht dargestellten Getriebemotor stetig umlaufend angetrieben wird, mittels Trag- und Stützrollen 20, 21 geführt.The overhead conveyor shown schematically in FIG. 3 essentially consists of the chain channel 6 and the running rail 4, not shown in more detail, on which trolleys 1 - so-called trolleys - run as load hangers. In the chain channel 6, an articulated drive chain 5, which is driven continuously by a gear motor, not shown, is guided by means of support and support rollers 20, 21.

An der Antriebskette 5 ist jeweils im Bereich zweier benachbarter Tragrollen 20 an nach unten aus dem Kettenkanal 6 herausragenden Tragwinkeln 19 das Antriebselement 7 befestigt. An dem in Transportrichtung T gesehen vorderen Ende des Antriebselements (in der Zeichnung links) ist eine in Richtung der Laufschiene 4 ragende Bremsklaue 3 und am gegenüberliegenden Ende des Antriebselements 7 ist ein nach unten ragender Mitnehmer 2 angeordnet.
Die Bremsklaue 3 und der Mitnehmer 2 sind über Bolzen 12, 12' in dem im Querschnitt U-förmigen Profil des Antriebselements 7 in jeweils entgegengesetzter Richtung schwenkbar gelagert. Über Tragbügel 18 ist das Antriebselement 7 mit den Tragwinkeln 19 verbunden. Im Förderbetrieb auf horizontaler Strecke oder bei Steigungsfahrt greift der Mitnehmer 2 an der vorderen Stoßkappe 15 des Förderwagens 1 an und schiebt ihn dadurch mit der Geschwindigkeit der umlaufenden Förderkette 5 vorwärts. Bei Gefällefahrt läuft der Förderwagen 1 mit der Stoßkappe 15 gegen die Bremsklaue 3 an und wird dadurch am Wegrollen gehindert. Insbesondere um die Förderwagen 1 eingleisen zu können, ist es notwendig, daß das Antriebselement 7 außer Eingriff mit einem Förderwagen 1 bringbar ist. Hierzu können die Bremsklaue 3 und der Mitnehmer 2 hochgeschwenkt werden. Beide Bauteile2, 3 sind daher, wie Figur 3 zeigt, entgegen ihrer Wirkrichtung, d.h.: in Richtung der Mitte (Hochachse) schwenkbar ausgebildet. Hierzu ist an dem dem Antriebselement 7 in der Wirkstellung zugewandten Ende beider Bauteile 2,3 eine horizontale Bohrung 9 außerhalb der gedachten Mittellinie ausgeführt. Durch diese Bohrung 9 ist ein Bolzen 12 gesteckt, der in den Seitenwangen 7a, 7b des Antriebselements 7 gelagert ist.
Durch diese außermittige Anordnung von Bremsklaue 3 und Mitnehmer 2 wird eine Schwenkbarkeit in die Richtung des schmaleren Teil der Außermittigkeit zugelassen.
In der entgegengesetzten Richtung wird ein Verschwenken durch das gegen die Innenseite 7c des Antriebselementes 7 anstoßende Ende von Bremsklaue 3 oder Mitnehmer 2 verhindert. Hierzu ist in bekannter Weise außerdem - wie Fig. 1 deutlich zeigt - das in Wirkstellung obere Ende des Mitnehmers 2 asymmetrisch so ausgestaltet, daß die in die nicht zugelassende Schwenkrichtung weisende Kante 2a bereits an der Innenseite 7c des Antriebselements 7 anliegt. Die Bremsklaue 3 ist im Grunde genommen identisch zum Mitnehmer 2 ausgestaltet und nur seitenverkehrt eingebaut.
Das in Wirklage der Innenseite 7c des Antriebselements 7 zugeordnete Ende des Mitnehmers 2 weist eine Nut 10 auf, die die Bohrung 9 radial schneidet [vereinfacht ausgedrückt: die Bohrung 9 ist geschlitzt]. Die Breite b der Nut 10 ist kleiner als der Durchmesser d der Bohrung 9. Bei einer auf den Mitnehmer 2 entgegen der Transportrichtung T einwirkenden Kraft wird, wenn die an dem Bolzen 12 resultierende Kraft ein bestimmtes Maß übersteigt, die Nut 10 aufgeweitet, und der Mitnehmer 2 springt vom Bolzen 12 ab. Hierzu muß der Unterschied zwischen der Breite b der Nut 10 und dem Durchmesser d der Bohrung 9 so gewählt sein, daß die das Herausschleudern bewirkende Kraft auf den Mitnehmer 2 immer größer sein muß, als die aus der Gewichtskraft des beladenen Förderwagens 1 bei Steigungsfahrt auf den Mitnehmer maximal einwirkende resultierende.
Aus Sicherheitsgründen weist die Bremsklaue 3 keine entsprechende Nut auf.The drive element 7 is fastened to the drive chain 5 in the region of two adjacent support rollers 20 at support angles 19 projecting downward from the chain channel 6. At the front end of the drive element seen in the transport direction T (left in the drawing) there is a brake claw 3 projecting in the direction of the running rail 4 and at the opposite end of the drive element 7 a driver 2 projecting downwards is arranged.
The brake claw 3 and the driver 2 are pivotally mounted in the opposite direction via bolts 12, 12 'in the cross-sectionally U-shaped profile of the drive element 7. The drive element 7 is connected to the support brackets 19 via the support bracket 18. In conveyor operation on a horizontal route or on a slope, the driver 2 engages on the front end cap 15 of the trolley 1 and thereby pushes it forward at the speed of the rotating conveyor chain 5. When driving downhill, the trolley 1 with the butt cap 15 runs against the brake claw 3 and is thereby prevented from rolling away. In particular, in order to be able to feed in the trolley 1, it is necessary that the drive element 7 can be brought out of engagement with a trolley 1. For this purpose, the brake claw 3 and the driver 2 can be swiveled up. Both components 2, 3 are therefore, as shown in FIG. 3, designed to be pivotable in the direction of the center (vertical axis) against their direction of action. For this purpose, a horizontal bore 9 is made outside the imaginary center line at the end of both components 2, 3 facing the drive element 7 in the active position. A bolt 12 is inserted through this bore 9 and is mounted in the side cheeks 7a, 7b of the drive element 7.
This eccentric arrangement of the brake claw 3 and driver 2 permits pivoting in the direction of the narrower part of the eccentricity.
Swiveling in the opposite direction is caused by the movement towards the inside 7c of the drive element 7 Preventing end of brake claw 3 or driver 2 prevented. For this purpose, as is clearly shown in FIG. 1, the upper end of the driver 2 in the active position is designed asymmetrically in such a way that the edge 2a pointing in the non-permitted pivoting direction already bears against the inside 7c of the drive element 7. The brake claw 3 is basically identical to the driver 2 and only installed upside down.
The end of the driver 2 assigned to the inner side 7c of the drive element 7 in operative position has a groove 10 which radially intersects the bore 9 [to put it simply: the bore 9 is slotted]. The width b of the groove 10 is smaller than the diameter d of the bore 9. In the case of a force acting on the driver 2 against the direction of transport T, if the force resulting on the bolt 12 exceeds a certain dimension, the groove 10 is widened and the Driver 2 jumps off the bolt 12. For this purpose, the difference between the width b of the groove 10 and the diameter d of the bore 9 must be selected so that the force acting on the driver 2, which causes it to be thrown out, must always be greater than that resulting from the weight of the loaded trolley 1 when driving uphill Driver resulting maximum impact.
For safety reasons, the brake claw 3 has no corresponding groove.

Damit der durch einen blockierten Förderwagen 1 herausgeschleuderte Mitnehmer 2 nicht in der Umgebung Schaden anrichten kann, ist in dem Mitnehmer 2 eine weitere horizontale Durchgangsbohrung 22 vorgesehen, in die beidseitig die offenen Enden eines U-förmig gebogenen Drahtbügels 11 eingesteckt sind. Der Drahtbügel 11 liegt mit seinem geschlossenen Ende zwischen den Tragbügeln 18 auf der Oberseite des Antriebselements auf. Der aus dem Bolzen 12 herausgedrückte Mitnehmer 2 bleibt folglich an diesem Drahtbügel 11 hängen. Das Antriebselement 7 kann dann durch die Antriebskette 5 ungehindert angetrieben werden, der Mitnehmer 2 weicht der Rolle 13 des Förderwagens 1 aus.So that the carrier 2 thrown out by a blocked trolley 1 cannot cause damage in the vicinity, a further horizontal through-bore 22 is provided in the carrier 2, into which the open ends of a U-shaped wire bracket 11 are inserted on both sides. The wire bracket 11 lies with its closed end between the support bracket 18 on the top of the drive element. The driver 2 pushed out of the bolt 12 consequently remains attached to this wire bracket 11. The drive element 7 can are then driven freely by the drive chain 5, the driver 2 evades the roller 13 of the trolley 1.

Wie aus Fig. 4 ersichtlich, können an der Antriebskette 5 außerdem Ausschieber 23 befestigt sein, die in Bezug auf die Transportrichtung T hinter jedem Förderwagen 1 angeordnet sind. Diese Ausschieber 23 dienen dazu an etwaigen, hier nicht gezeigten Verzweigungsstellen der Förderstrecke (Weichen) den auszugleisenden Förderwagen 1 in den Nebenstrang zu schieben. Die Ausschieberklaue 24 kann genauso ausgebildet sein wie die zuvor beschriebene Mitnehmerklaue 2. Dadurch wird dann sichergestellt, daß eine Beschädigung des Ausschiebers 23 dann wirksam verhindert wird, wenn ein ausgegleister Förderwagen auf ein Hindernis im abzweigenden Förderstrang stößt, solange er noch nicht völlig aus dem derzeitigen Hauptförderstrang transportiert ist. Des weiteren ist dadurch sichergestellt, daß wenn der Mitnehmer 2 funktionsgemäß aus dem Antriebselement 7 herausgedrückt wird und die umlaufende Förderkette 5 nicht sofort gestoppt wird, der dem Förderwagen nachgeordnete Ausschieber 23, bzw. die Ausschieberklaue 24, unbeschädigt bleibt. Die Ausbildung der Auschieberklaue 24 sollte folglich ebeso erfindungsgemäß erfolgen.

Figure imgb0001
As can be seen from FIG. 4, pushers 23 can also be fastened to the drive chain 5 and are arranged behind each trolley 1 with respect to the transport direction T. These pushers 23 are used to push the trolley 1 to be emptied into the secondary line at any branching points of the conveyor line (switches), which are not shown here. The pusher claw 24 can be designed in exactly the same way as the driver claw 2 described above. This then ensures that damage to the pusher 23 is effectively prevented if a greased trolley encounters an obstacle in the branching conveyor line, as long as it is not yet completely out of the current one Main conveyor line is transported. This also ensures that when the driver 2 is pressed out of the drive element 7 in terms of its function and the rotating conveyor chain 5 is not stopped immediately, the pusher 23, or the pusher claw 24, which is arranged downstream of the trolley remains undamaged. The design of the pusher claw 24 should consequently also take place according to the invention.
