Abstract

Die Erfindung wird angewendet, wenn in einem Transportsystem in horizontaler Richtung genau uebereinander und parallel zueinander mehrere Transportebenen angeordnet sind, die unabhaengig voneinander betrieben werden koennen. Das Transportorgan wird, waagerecht um einen Umlenkteller, aus der Transportebene herausgefuehrt und ueber ein Antriebsrad gelenkt. Die sich bildende Dehnschlaufe wird von einer Auflage aufgefangen. Anschliessend wird das Transportorgan wieder in die urspruengliche Transportebene zurueckgefuehrt.The invention is applied when in a transport system in the horizontal direction exactly above each other and parallel to each other several transport planes are arranged, which can be operated independently of each other. The transport organ is led out of the transport plane horizontally around a deflecting plate and steered over a drive wheel. The forming Dehnschlaufe is collected by a pad. Subsequently, the transport member is returned to the original transport level.

Description

Das Transportorgan 1 wird an der Umlenkscheibe 2 um 90" waagerecht aus der Transportebene herausgeführt, während die Werkstücke 3 innerhalb der Werkstückführung 4 in der Transportebene verbleiben. Anschließend erfolgt die Umschlingung des Antriebsrades 5 des Antriebes β um etwa 75" bis 80°. Das ablaufende Transportorgan bildet die Dehnschlaufe 7 auf der Auflage 8. Dabei erfolgt eine seitliche Umlenkung um 180° in Aufwärtsrichtung. Das am Grundgestell 9 befestigte Antriebsgestell 10 mit seinen Führungen übernimmt das Transportorgan, leitet es in die ursprüngliche Transportebene zurück und übernimmt so den Weitertransport der Werkstücke. Antriebe benachbarter Transportebenen werden so gegeneinander versetzt angeordnet, daß sie sich nicht behindernThe transport member 1 is led out of the transport plane 90 ° horizontally on the deflecting disk 2, while the workpieces 3 remain in the transport plane within the workpiece guide 4. The wrapping of the drive wheel 5 of the drive β then takes place by about 75 ° to 80 °. The running transport organ forms the stretch loop 7 on the support 8. Here, a lateral deflection by 180 ° in the upward direction. The drive frame 10 attached to the base frame 9 with its guides takes over the transport organ, returns it to the original transport plane and thus takes over the further transport of the workpieces. Drives adjacent transport planes are arranged offset from each other so that they do not interfere

Die Verwendung der beschriebenen erfindungsgemäßen Lösung zeichnet sich durch folgende Vorteile aus: The use of the described solution according to the invention is characterized by the following advantages:

• Es werden Transportebenenabstände realisiert, die vom Transportorgan, den Werkstücken sowie den notwendigen Führungen abhängen, jedoch nicht vom Antrieb oder Antriebsrad, da diese nicht in der Transportebene angeordnet sind. Es sind Abstände möglich, die kleiner als der Antriebsraddurr.hmesser oder der Antrieb sind.• Transport plane distances are realized which depend on the transport organ, the workpieces and the necessary guides, but not on the drive or drive wheel, since these are not arranged in the transport plane. There are distances that are smaller than the Antriebsraddurr.hmesser or the drive.

• Die Dehnschlaufe hat keinen Einflufo auf den Abstand zwischen den Transportebenen.• The stretch loop has no influence on the distance between the transport planes.

• Durch die Umschlingung kann ein kontinuierlicher Werkstückfluß realisiert werden.• By wrapping a continuous workpiece flow can be realized.

• In den vorhandenen Platzverhältnissen kann eine maximale Anzahl an Transportobenen untergebracht werden.• A maximum number of transport floors can be accommodated in the available space.

Claims

Drive arrangement for a flexible, curvilinear transport member, characterized in that a transport member (1) led out of a transport plane and via a drive wheel (5) is directed so that a wrap arises, that the wrap is held by a support (8) and that the transport member (1) is then returned back to the transport plane.

Field of application of the invention

The invention is used when several floors are arranged one above the other in a transport system and the floor level to be set independently of the drive assembly.

Characteristic of the known state of the art

In DE-OS 2235046 the use of chains in the form of a Transportovals or a Transporterpentine is described. The disadvantage here is that the necessary üehnschlaufe is arranged in the transport plane and thus negatively affected the floor height.

DE-OS 2351688 describes the use of a plastic chain, in which the expansion loop is arranged in the transport plane and the Anfriebsraddurchmesser also enters the floor level. In addition, it is still necessary here to remove the workpieces the transport member, to pass them between and re-supply the transport member.

Object of the invention

The aim of the invention is to provide a drive solution for a flexible, curved transport member, which ensures a continuous workpiece transport, the maximum space available uses, thereby enabling a kompaktere, lighter and more cost-effective design.

Explanation of the essence of the system

The object of the invention is to arrange a drive for a transport plane in a plurality of transport levels he thalten transport system so that the necessary distance between two adjacent, parallel parallel in each other and exactly superimposed transport planes is determined only by the transport member, the workpieces and the necessary guides , obwoi.i the engagement of the drive wheel takes place in the transport member from below. The object is achieved according to the invention as follows:

On a base frame are arranged in the horizontal direction exactly one above the other and parallel to each other several transport planes. In these individual transport planes, which can be operated independently of each other, there is a continuous workpiece transport on a transport member, which is driven by engagement from below. In order to keep the overall height of the base frame low, the adjacent transport planes are to be arranged as densely as possible above each other. The curvilinear transport member is led out horizontally about a Umlenkteller, preferably by 90 °, from the transport plane and a with the. ' drive connected drive wheel steered. This drive wheel is looped around 75 ° -80 ° in the vertical direction. The running of the drive wheel conveyor organ slides on a support, which is also inclined by 75 ° to 80 ^s in the vertical direction. At the same time the forming stretch loop is collected. Subsequently, the transport member is guided back by guide means under the incoming part of the transport member and back to the original transport plane.
The wrapping thus carried out makes it possible to transport the workpieces by means of guide devices in a straight line.
