Abstract

The conveyor comprises a roller-mounted transport carriage (1) with one or more entrainment members (36,37) on the carriage engaging in recesses of the drive means (4,6) during normal transport mode. In the event of overload the entrainment member is brought out of the recesses in order to stop the carriage. The entrainment member can be mounted sprung against the drive means. The entrainment member and drive means can be arranged to interact so that the entrainment member is disengaged by the drive means. The position (a1) of both the entrainment members may correspond to multiple of divisions of the drive means.

Description

Die Erfindung betrifft eine Fördervorrichtung gemäß dem Oberbegriff der Ansprüche 1, 6 und 10.The invention relates to a conveyor device according to the preamble of claims 1, 6 and 10.

Aus der DE 33 04 568 C2 ist eine Fördervorrichtung für den Transport von Lasten bekannt. Diese Fördervorrichtung besteht im wesentlichen aus einem auf einer Führungsbahn fahrenden Transportwagen und umlaufenden Ketten. An dem Transportwagen sind zwei in die Ketten eingreifende Kettenräder gelagert, die den Transportwagen gegen die Laufrichtung der Ketten antreiben. Diese Kettenräder sind zum störungsfreien überlauf von einer ersten zu einer zweiten Kette in einem begrenzten Schwenkwinkel gefedert schwenkbar gelagert.
Nachteilig ist an dieser Fördervorrichtung, daß keine Sicherheitsvorrichtung gegen Schäden, die beim Auflaufen des Transportwagens gegen ein Hindernis entstehen können, vorgesehen ist.
From DE 33 04 568 C2 a conveyor device for the transport of loads is known. This conveyor essentially consists of a transport carriage traveling on a guideway and revolving chains. Two chain wheels engaging in the chains are mounted on the transport carriage, which drive the transport carriage against the running direction of the chains. These sprockets are spring-mounted for spring-free overflow from a first to a second chain in a limited pivoting angle.
The disadvantage of this conveyor device is that no safety device against damage that can occur when the trolley hits an obstacle is provided.

Die EP 05 87 015 A1 beschreibt eine Förderanlage mit einem auf einer Schienenanlage laufenden Wagen. Dieser Wagen weist zwei Paare von Laufrädern auf. Angetrieben wird dieser Wagen mittels einer umlaufenden Doppelkette, auf die eine mit dem Wagen verbundene Reibleiste drückt.EP 05 87 015 A1 describes a conveyor system with a carriage running on a rail system. This car has two pairs of wheels. This car is driven by a rotating double chain, on which a friction bar connected to the car presses.

Nachteilig an dieser Förderanlage ist, daß die als Rutschkupplung dienende reibschlüssige Verbindung zwischen Kette und Wagen keine gleichbleibenden Reibkoeffizienten aufweist. Beispielsweise durch eindringendes öl oder Schmutz wird der Reibkoeffizient verändert. Somit ist eine Funktion als Überlastkupplung nicht sicher gewährleistet.A disadvantage of this conveyor system is that the frictional connection between chain and carriage serving as a slip clutch does not have a constant coefficient of friction. The coefficient of friction is changed, for example, by penetrating oil or dirt. A function as an overload clutch is therefore not guaranteed.

Der Erfindung liegt die Aufgabe zugrunde, eine Fördervorrichtung zu schaffen.The invention has for its object to provide a conveyor.

Diese Aufgabe wird erfindungsgemäß durch eine Fördervorrichtung mit den Merkmalen der kennzeichnenden Teile der Ansprüche 1, 6 und 10 gelöst.This object is achieved by a conveyor device with the features of the characterizing parts of claims 1, 6 and 10.

In vorteilhafter Weise können durch die erfindungsgemäße Fördervorrichtung Schäden vermieden werden, die beispielsweise infolge Auflaufens des Transportwagens gegen ein Hindernis entstehen könnten. Dieser Vorteil wird durch die als Rutschkupplung wirkenden Mitnehmer erreicht.
Zudem ist es durch die Anordnung zweier Mitnehmer möglich, einen störungsfreien Übergang von einem ersten zu einem zweiten Antriebsmittel möglich. Dieser störungsfreie Übergang ist unabhängig von der Transportrichtung des Transportwagens erreichbar, d.h. der Transportwagen kann vorwärts und rückwärts verwendet werden.
Mittels gefederter Mitnehmer, bei denen die auf diese wirkende Federkraft einstellbar ist, kann eine zum Durchrutschen notwendige Kraft eingestellt werden.
Damage which could arise, for example, as a result of the trolley hitting an obstacle can advantageously be avoided by the conveyor device according to the invention. This advantage is achieved by the drivers acting as a slip clutch.
In addition, the arrangement of two drivers enables a trouble-free transition from a first to a second drive means. This trouble-free transition can be achieved regardless of the direction of transport of the trolley, ie the trolley can be used forwards and backwards.
By means of spring-loaded drivers, where the on this acting spring force is adjustable, a force necessary for slipping can be set.

Vorteilhaft ist weiterhin einen Abstand der beiden Mitnehmer entsprechend einer Teilung der Antriebsmittel festzulegen, da dann beide Mitnehmer zur Kraftübertragung dienen und die Belastung eines einzelnen Mitnehmers reduziert wird.
Insbesondere bei Verwendung von Zahnriemen als Antriebsmittel ist es vorteilhaft, die Mitnehmer als ein mit mehreren Zähnen versehenes Stück eines Zahnriemens auszubilden, da dadurch eine Belastung der einzelnen Zähne reduziert wird.
It is also advantageous to define a distance between the two drivers according to a division of the drive means, since then both drivers are used for power transmission and the load on an individual driver is reduced.
In particular when using toothed belts as the drive means, it is advantageous to design the drivers as a piece of toothed belt provided with several teeth, since this reduces the load on the individual teeth.

Die erfindungsgemäße Fördervorrichtung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.The conveyor device according to the invention is shown in the drawing and is described in more detail below.

Eine Fördervorrichtung zum Transport von Lasten, insbesondere von Papierrollen, weg von und zu einer Rollenrotationsdruckmaschine, besteht im wesentlichen aus einem Transportwagen 1, Führungen 2, 3 und umlaufenden, mit Aussparungen versehenen Antriebsmitteln 4, 6.A conveying device for transporting loads, in particular paper rolls, away from and to a web-fed rotary printing press essentially consists of a transport carriage 1, guides 2, 3 and rotating drive means 4, 6 provided with cutouts.

Der Transportwagen 1 ist an seinem Fahrgestell 7, z. B. einem U-Profil 7, mit vier Laufrollen 8 versehen, die auf jeweils zugehörigen Lagerzapfen 9 frei drehbar gelagert sind.
Auf einer Basisseite 11 des auf dem Kopf stehenden U-Profils 7 ist eine Basisseite 12 eines ebenfalls auf dem Kopf stehenden T-Profils 13 befestigt. An einem nach oben stehenden Schenkel 14 dieses T-Profils 13 ist eine prismenförmige Lastaufnahme 16 angeordnet. Diese Lastaufnahme 16 erstreckt sich beispielsweise In Transportrichtung T über die gesamte Länge des Transportwagens 1.
The trolley 1 is on its chassis 7, z. B. a U-profile 7, provided with four rollers 8, which are freely rotatably mounted on the respective journal 9.
On a base side 11 of the upside-down U-profile 7, a base side 12 of an upside-down T-profile 13 is fastened. A prism-shaped load bearing 16 is arranged on an upstanding leg 14 of this T-profile 13. This load bearing 16 extends, for example, in the transport direction T over the entire length of the Transport trolley 1.

Die Führungen 2, 3 sind als U-Profile ausgebildet, die in Transportrichtung parallel, einander zugewandt verlaufend angeordnet sind. Diese U-Profile 2, 3 sind jeweils mit einem unten liegenden Schenkel 17, 18 auf einer Grundplatte 19 befestigt, während gegenüberliegende Schenkel 21, 22 mit jeweils einer Abdeckplatte 23, 24 versehen sind. Die Abdeckplatten 23, 24 sind derart zueinander beabstandet, daß sich ein in Transportrichtung T verlaufender Spalt 26 mit einer Breite b26 ergibt. In diesem Spalt 26 verläuft der Schenkel 14 des T-Profils 13. Über die Abdeckplatten 23, 24 ragt die Lastaufnahme 16 heraus.
Auf der Grundplatte 19 ist mittig zu den Führungen 2, 3 zur Führung und Abstützung des Antriebsmittels 4, 6 ein nach oben offenes C-Profil 27 befestigt. In diesem C-Profil 27 läuft das Antriebsmittel 4, 6.
The guides 2, 3 are designed as U-profiles, which are arranged parallel, facing each other in the transport direction. These U-profiles 2, 3 are each fastened to a base plate 19 with a leg 17, 18 located at the bottom, while opposite legs 21, 22 are each provided with a cover plate 23, 24. The cover plates 23, 24 are spaced apart from one another in such a way that a gap 26 with a width b26 extends in the transport direction T. The leg 14 of the T-profile 13 runs in this gap 26. The load receiver 16 protrudes beyond the cover plates 23, 24.
On the base plate 19, an upwardly open C-profile 27 is fastened in the middle to the guides 2, 3 for guiding and supporting the drive means 4, 6. The drive means 4, 6 runs in this C-profile 27.

Unterhalb der Grundplatte 19 ist eine Welle 28 drehbar in Lagerböcken 29, 31 gelagert. Die Welle 28 wird von einem Getriebemotor 32 angetrieben und weist ein drehsteifes, mit dem Antriebsmittel 4, 6 fluchtendes Umlenkrad 33 auf.
In einem Übergangsbereich endet das erste Antriebsmittel 4, indem es um das Umlenkrad 33 unter die Grundplatte 19 zurückgeführt wird. In einem Abstand zu dem Umlenkrad 33 des ersten Antriebsmittels 4 ist dann das zweite, weiterführende Antriebsmittel 6 angeordnet.
Below the base plate 19, a shaft 28 is rotatably mounted in bearing blocks 29, 31. The shaft 28 is driven by a gear motor 32 and has a torsionally rigid deflection wheel 33 aligned with the drive means 4, 6.
The first drive means 4 ends in a transition region in that it is guided back around the deflection wheel 33 under the base plate 19. The second, further drive means 6 is then arranged at a distance from the deflection wheel 33 of the first drive means 4.

Dieses Antriebsmittel 6 wird von unterhalb der Grundplatte 19 verlaufend um ein Umlenkrad 34 in Transportrichtung T verlaufend umgelenkt.This drive means 6 is deflected from below the base plate 19 to extend around a deflection wheel 34 in the transport direction T.

An dem Fahrgestell 7 des Transportwagens 1 ist mindestens ein, im vorliegenden Beispiel zwei Mitnehmer 36, 37 angeordnet. Diese Mitnehmer 36, 37 greifen formschlüssig derart in das jeweilige Antriebsmittel 4, 6 ein, so daß im Übergangsbereich zwischen den beiden Antriebsmitteln 4, 6 zumindest einer der beiden Mitnehmer formschlüssig in ein Antriebsmittel 4, 6 eingreift.
Die Mitnehmer 36, 37 greifen während des "normalen" Transportvorganges (d. h. während der Bewegung des Transportwagens 1) formschlüssig in Aussparungen der Antriebsmittel 4, 6 ein. Abweichend vom "normalen" Transportvorgang sind die Mitnehmer 36, 37 derart bewegbar gelagert, daß sie aus einem Bewegungsraum des Antriebsmittels 4, 6, d. h. außer Eingriff bringbar sind, z. B. zum Stillstand des Transportwagens 1.
Dies kann, wie in den Ausführungsbeispielen, durch Krafteinwirkung der Antriebsmittel 4, 6 geschehen, beispielsweise bei überlast (Auflaufen des Transportwagens 1 auf ein Hindernis). Es ist aber auch möglich, den Transportwagen 1 mittels steuerbaren Mitteln, z. B. Elektromotoren, von den Antriebsmitteln 4, 6 zu entkoppeln. Die Mitnehmer 36, 37 werden mittels der z. B. fernsteuerbaren Elektromotoren außer Eingriff von den Antriebsmitteln 4, 6 gebracht.
At least one, in the present example two drivers 36, 37 is arranged on the chassis 7 of the transport carriage 1. These drivers 36, 37 engage in a form-fitting manner in the respective drive means 4, 6, so that at least one of the two drivers engages in a drive form 4, 6 in the transition region between the two drive means 4, 6.
The drivers 36, 37 engage positively in recesses of the drive means 4, 6 during the "normal" transport process (ie during the movement of the transport carriage 1). Deviating from the "normal" transport process, the drivers 36, 37 are movably mounted such that they can be disengaged from a movement space of the drive means 4, 6, ie. B. to a standstill of the trolley 1.
As in the exemplary embodiments, this can be done by the force of the drive means 4, 6, for example in the event of an overload (impact of the transport carriage 1 on an obstacle). But it is also possible to use the trolley 1 by means of controllable means, for. B. electric motors to decouple from the drive means 4, 6. The drivers 36, 37 are by means of the z. B. remote-controlled electric motors disengaged from the drive means 4, 6.

Die beiden Antriebsmittel 4, 6 weisen beispielsweise infolge unterschiedlich hoher Belastung um z. B. +/- 10% verschieden große Transportgeschwindigkeiten v4, z. B. 0,2 m/s, v6, z. B. 0,22 m/s auf.The two drive means 4, 6 have z. B. +/- 10% different transport speeds v4, z. B. 0.2 m / s, v6, z. B. 0.22 m / s.

Die Antriebsmittel 4, 6 können wie in den ersten drei Ausführungsbeispielen dargestellt aus Rollenketten 38, 39 oder wie im vierten Beispielen dargestellt aus Zahnriemen 41, 42 bestehen.The drive means 4, 6 can, as shown in the first three exemplary embodiments, consist of roller chains 38, 39 or, as shown in the fourth examples, of toothed belts 41, 42.

In einem ersten Ausführungsbeispiel sind an dem Fahrgestell 7 ein erster 43 und ein zweiter Rastbolzen 44 angeordnet. Diese Rastbolzen 43, 44 sind derart in einem Abstand a1, z. B. 571 mm, in Transportrichtung T beabstandet, daß während der zweite Rastbolzen 44 noch in die erste Rollenkette 38 eingreift, der erste Rastbolzen 43 bereits In die zweite Rollenkette 39 eingreift. Um eine eventuell bestehende Differenz eines Abstandes zweier Zahnlücken der jeweiligen Rollenkette 37, 38 zu dem Abstand a1 der Rastbolzen 43, 44 ausgleichen zu können, sind beide Rastbolzen 43, 44 derart gefedert angeordnet, so daß zumindest einer der beiden Rastbolzen 43, 44 eine Bewegung annähernd senkrecht zur Transportrichtung T ausführen kann. Dazu sind die Rastbolzen 43, 44 jeweils in einer senkrecht verlaufenden Führungsbuchse 46, 47 bezüglich des Fahrgestells 7 des Transportwagens 1 verschiebbar gelagert.In a first embodiment, a first 43 and a second locking bolt 44 are arranged on the chassis 7. These locking bolts 43, 44 are at a distance a1, z. B. 571 mm, spaced in the transport direction T that while the second locking pin 44 still engages in the first roller chain 38, the first locking pin 43 already engages in the second roller chain 39. In order to be able to compensate for a possibly existing difference between a distance between two tooth gaps of the respective roller chain 37, 38 and the distance a1 of the locking bolts 43, 44, both locking bolts 43, 44 are arranged in a spring-loaded manner so that at least one of the two locking bolts 43, 44 makes a movement can run approximately perpendicular to the transport direction T. For this purpose, the locking bolts 43, 44 are each slidably mounted in a vertical guide bushing 46, 47 with respect to the chassis 7 of the transport carriage 1.

Der Abstand a1, z. B. 571 mm, der beiden Rastbolzen 43, 44 ist größer oder gleich einem Abstand a2, z. B. 400 mm, von Drehachsen der Umlenkräder 33, 34 und entspricht beispielsweise einem Vielfachen einer Teilung des Antriebsmittels 4, 6.The distance a1, e.g. B. 571 mm, the two locking bolts 43, 44 is greater than or equal to a distance a2, z. B. 400 mm, of axes of rotation of the deflection wheels 33, 34 and corresponds for example to a multiple of a division of the drive means 4, 6th

Die Rastbolzen 43, 44 sind an ihrem der Rollenkette 38, 39 zugewandten Ende mit einer gerundeten Kuppe 48 versehen. Ihr zweites Ende weist einen als Anschlag gegen eine Verengung 49 der Führungsbuchse 46, 47 wirkenden Bund 51 auf. Gegen diesen Bund 51 des Rastbolzens 43, 44 drückt ein erstes Ende einer jeweiligen Druckfeder 52, 53 deren zweites Ende beispielsweise gegen eine Einstellschraube 54, 56 wirkt.
Diese Einstellschraube 54, 56 ist senkrecht zur Transportrichtung T verstellbar, so daß die auf den Rastbolzen 43, 44 wirkende Federkraft einstellbar ist.
The locking bolts 43, 44 are provided with a rounded tip 48 at their end facing the roller chain 38, 39. Its second end has a collar 51 which acts as a stop against a constriction 49 of the guide bushing 46, 47. A first end of a respective compression spring 52, 53 presses against this collar 51 of the locking bolt 43, 44, the second end of which acts, for example, against an adjusting screw 54, 56.
This adjusting screw 54, 56 is adjustable perpendicular to the transport direction T, so that the spring force acting on the locking bolts 43, 44 is adjustable.

In einem zweiten Ausführungsbeispiel werden anstelle der Rastbolzen 43, 44 Segmente 57, 58 eines Kettenrades verwendet. Auch diese Segmente 57, 58 greifen formschlüssig in die entsprechenden Rollenketten 38, 39 ein. Die auf diese Segmente 57, 58 wirkende Federkraft ist einstellbar. Diese Segmente 57, 58 können senkrecht zur Transportrichtung T verschiebbar und in Transportrichtung T unbeweglich in Führungen gelagert sein.In a second exemplary embodiment, segments 57, 58 of a chain wheel are used instead of the locking bolts 43, 44. These segments 57, 58 also engage positively in the corresponding roller chains 38, 39. The spring force acting on these segments 57, 58 is adjustable. These segments 57, 58 can be displaced perpendicular to the transport direction T and can be immovably mounted in guides in the transport direction T.

In einem dritten Ausführungsbeispiel sind zylinderartige Druckstücke 59, 61, deren Längsachse sich quer zur Transportrichtung T erstreckt, am Fahrgestell 7 in Transportrichtung T schwenkbar gelagert. Dazu ist ein Ende eines jeweiligen Schwenkhebels 62, 63 mittels eines Gelenkes 64, 66 in Transportrichtung T schwenkbar gelagert. An einem zweiten Ende des Schwenkhebels 62, 63 ist das Druckstück 59, 61 befestigt. Dieser Schwenkhebel 62, 63 ist mittels einstellbarer Druckfedern 67 gefedert eingespannt.In a third embodiment are cylindrical Thrust pieces 59, 61, the longitudinal axis of which extends transversely to the transport direction T, are pivotably mounted on the chassis 7 in the transport direction T. For this purpose, one end of a respective pivot lever 62, 63 is pivotably mounted in the transport direction T by means of a joint 64, 66. The pressure piece 59, 61 is fastened to a second end of the pivot lever 62, 63. This pivot lever 62, 63 is spring-loaded by means of adjustable compression springs 67.

Anstelle der Rastbolzen 43, 44 des ersten Beispiels oder der Segmente 57, 58 der Kettenräder können auch zahnstangenartige, ebene Teile verwendet werden.
Sind wie in einem vierten Ausführungsbeispiel Zahnriemen 41, 42 mit Doppelverzahnung als Antriebsmittel 4, 6 vorgesehen, können auch ebene Teile 71, 72 eines Zahnriemens als Mitnehmer 36, 37 angeordnet sein (Fig. 5).
Instead of the locking bolts 43, 44 of the first example or the segments 57, 58 of the chain wheels, rack-like, flat parts can also be used.
If, as in a fourth exemplary embodiment, toothed belts 41, 42 with double toothing are provided as drive means 4, 6, flat parts 71, 72 of a toothed belt can also be arranged as drivers 36, 37 (FIG. 5).

Hierbei können die beiden einzelnen als Zahnriemen ausgebildete Mitnehmer 36, 37 auch miteinander gekoppelt sein, d.h. es kann ein einziger durchgehender Mitnehmer 73 vorgesehen sein. Dieser Mitnehmer 73 kann wie im fünften Ausführungsbeispiel als Zahnriemenelement 73 ausgebildet sein und ist mittels einstellbarer Druckfedern 74 bezüglich des Transportwagens 1 sowohl in als auch senkrecht zur Transportrichtung T verschiebbar gelagert. Im vorliegenden Beispiel ist die Länge l73 des Zahnriemenelementes 73 größer als der Abstand a2 der Drehachsen der Umlenkräder 33, 34 (Fig. 6).Here, the two individual drivers 36, 37 designed as toothed belts can also be coupled to one another, ie a single continuous driver 73 can be provided. As in the fifth exemplary embodiment, this driver 73 can be designed as a toothed belt element 73 and is mounted displaceably with respect to the transport carriage 1 both in and perpendicularly to the transport direction T by means of adjustable compression springs 74. In the present example, the length l73 of the toothed belt element 73 is greater than the distance a2 Axes of rotation of the deflection wheels 33, 34 (Fig. 6).

In einem sechsten Beispiel sind die Mitnehmer 68, 69 umlaufend als Kettenrad 68, 69 bzw. Zahnriemenrad oder Zahnriemenband ausgebildet. Diese drehbaren, umlaufenden Mitnehmer 68, 69 sind jeweils am Fahrgestell 7 über eine Rutschkupplung um mehr als 360° drehbar gelagert und wahlweise drehfest mit dem Transportwagen 1 verbindbar. Während des "normalen" Betriebes sind die Kettenräder 68, 69 drehfest mit dem Transportwagen 1 verbunden. Ein bei Überlast (z. B. bei Auflaufen gegen ein Hindernis) zur Drehung, d. h. zum Entkoppeln des jeweiligen Kettenrades 68, 69 erforderliches Drehmoment ist mittels der einstellbaren Rutschkupplung festlegbar (Fig. 7). Es ist aber auch möglich, die umlaufenden Mitnehmer 68, 69 vom/an den Transportwagen 1 mittels steuerbaren Mitteln, z. B. Elektromotoren, zu koppeln bzw. zu entkoppeln.
Dadurch bleibt der Transportwagen 1 auch bei umlaufenden Ketten stehen. Dies ist vorteilhaft, wenn mit einem Antriebsmittel 4, 6 mehrere Transportwagen transportiert werden.
In a sixth example, the drivers 68, 69 are formed all around as a chain wheel 68, 69 or toothed belt wheel or toothed belt belt. These rotatable, revolving drivers 68, 69 are each mounted on the chassis 7 via a slip clutch so as to be rotatable by more than 360 ° and can optionally be connected in a rotationally fixed manner to the transport carriage 1. During "normal" operation, the chain wheels 68, 69 are connected to the transport carriage 1 in a rotationally fixed manner. A torque required in the event of an overload (for example when running into an obstacle) for rotation, ie for decoupling the respective sprocket 68, 69, can be determined by means of the adjustable slip clutch (FIG. 7). However, it is also possible to move the circumferential drivers 68, 69 from / to the trolley 1 by means of controllable means, for. B. electric motors to couple or decouple.
As a result, the transport carriage 1 remains stationary even with rotating chains. This is advantageous if a plurality of transport carriages are transported with one drive means 4, 6.

Die Funktionsweise der erfindungsgemäßen Fördervorrichtung, z. B. des ersten Ausführungsbeispiels, ist folgendermaßen:The operation of the conveyor device according to the invention, for. B. the first embodiment is as follows:

Der Transportwagen 1 wird in Transportrichtung T transportiert. Dabei greifen vorzugsweise beide Mitnehmer 36, 37 gleichzeitig in das erste Antriebsmittel 4 ein. Gelangt nun der Transportwagen 1 in den Übergangsbereich zwischen dem ersten 4 und zweiten Antriebsmittel 6 läuft der vorlaufende Mitnehmer 36 aus dem ersten Antriebsmittel 4 heraus. Infolge der weiteren Fortbewegung des Transportwagens 1 wird der erste Mitnehmer 36 zu einem Anlaufbereich des zweiten Antriebsmittels 6 gebracht. Trifft nun der Mitnehmer 36 nicht auf eine Zahnlücke sondern auf einen Zahn bzw.
Rolle des zweiten Antriebsmittels 6, so drückt der Zahn bzw. die Rolle den Mitnehmer 36 aus dem Bewegungsraum des zweiten Antriebsmittels 6. Zwischen dem Transportwagen 1 und dem zweiten Antriebsmittel 6 erfolgt eine Relativbewegung, da entweder der Transportwagen 1 mittels des zweiten noch in das erste Antriebsmittel 4 eingreifenden Mitnehmers 37 mit der Transportgeschwindigkeit v4 transportiert wird oder aber dieser bereits außer Eingriff ist. Der Transportwagen 1 weist in diesem Übergangsbereich eine von der Transportgeschwindigkeit v6 des zweiten Antriebsmittels 6 verschiedene Transportgeschwindigkeit auf.
Durch diese Relativbewegung zwischen dem Transportwagen 1 und dem zweiten Antriebsmittel 6 wird der erste Mitnehmer 36 zu einer Zahnlücke verschoben und rastet mittels Federkraft in diese ein. Der erste Mitnehmer 36 greift in das zweite Antriebsmittel 6 formschlüssig ein und treibt so den Transportwagen 1 an.
The transport carriage 1 is transported in the transport direction T. Both drivers 36, 37 preferably engage in the first at the same time Drive means 4 a. If the transport carriage 1 now reaches the transition area between the first 4 and second drive means 6, the leading driver 36 runs out of the first drive means 4. As a result of the further movement of the transport carriage 1, the first driver 36 is brought to a start-up area of the second drive means 6. If the driver 36 does not meet a tooth gap but a tooth or
Roller of the second drive means 6, the tooth or roller presses the driver 36 out of the movement space of the second drive means 6. A relative movement takes place between the transport carriage 1 and the second drive means 6, since either the transport carriage 1 is still in the first by means of the second Drive means 4 engaging driver 37 is transported at the transport speed v4 or this is already out of engagement. The transport carriage 1 has a transport speed different from the transport speed v6 of the second drive means 6 in this transition region.
As a result of this relative movement between the transport carriage 1 and the second drive means 6, the first driver 36 is displaced to a tooth gap and engages in it by means of spring force. The first driver 36 engages in the second drive means 6 in a form-fitting manner and thus drives the transport carriage 1.

Wird die Bewegung des Transportwagens 1 beispielsweise infolge eines Hindernisses blockiert, werden die Mitnehmer 36, 37 gegen die Federkraft aus den Zahnlücken der entsprechenden Antriebsmittel 4, 6 herausgedrückt.
Das Antriebsmittel 4, 6 dreht weiter, während der Transportwagen 1 steht. Die Mitnehmer 36, 37 wirken so auch als Rutschkupplung, die weitgehend unabhängig von Reibkoeffizienten wirkt.
If the movement of the transport carriage 1 is blocked, for example as a result of an obstacle, the Driver 36, 37 pressed out of the tooth gaps of the corresponding drive means 4, 6 against the spring force.
The drive means 4, 6 continues to rotate while the trolley 1 is stationary. The drivers 36, 37 thus also act as a slip clutch, which acts largely independently of the coefficient of friction.
