DE202006007529U1 - Roller conveyer bed for industrial mechanical handling system has drive wheels with gaps in outer periphery - Google Patents

Abstract

A roller conveyer system has a series of adjacent parallel full-width rollers separated by gaps. The gap between each pair of rollers is bridged by a drive wheel (3) located under and in contact with the rollers (1). The drive wheel outer margin bears one or more gaps that temporarily interrupt power transmission.

Description

The The invention relates to a drive for a roller conveyor with at least one driven impeller used to produce a Friction with at least one carrying roller of a roller conveyor in Active compound is.

such Drives for the carrying rollers of roller conveyors have long been known in practice. For the driven running or friction wheels it is usually arranged below the idlers Rollers which are spring-loaded against the support rollers arranged above them pressed to power them. In practice, it has turned out that in the course of operation due to the impeller drive vibrations transferred to the carrying rollers can be the proper transport of to be promoted on the support rollers Endanger goods.

From that Based on the object of the invention, a drive for one roller conveyors to create, with good drive transmission a substantially vibration-free drive of the idlers guaranteed.

The solution This task is inventively characterized in that the contact surface interrupted between the driven impeller and the support roller is trained.

By the displacement of the invention drive transmission on individual interrupted sections of the lateral surface of the Impeller has succeeded for the first time, a continuously quiet Running of the driven carrying roller with consistently good drive transmission to obtain. As opposed to forming one over the entire axial length of the impeller extending contact area, As is the case in the prior art, in the embodiment according to the invention possibly occurring vibrations due to the only partial contacting compensated by impeller and carrying roller.

According to one first practical embodiment The invention proposes that on the lateral surface of the Impeller at least two substantially parallel to each other and the diameter of the impeller enlarging circumferential annular areas are formed. In this embodiment, the circumferential rings on the lateral surface applied to the impeller and form the contact surfaces the driven roller to be driven.

With a second practical embodiment The invention proposes that in the lateral surface of the Impeller at least one reducing the diameter of the impeller circumferential Einkehlungen is formed. This embodiment represents, as it were, the reversal of the previously described embodiment in this case, since the ones in contact with the carrying roller come into contact Ring areas are formed by that in the lateral surface of the Impeller at least one circumferential groove is incorporated.

Around a good drive transmission from the impeller to ensure the idler, is with the invention furthermore proposed that the surface of the lateral surface of the Impeller at least in the contact with the support roller in contact Regions with a friction-increasing material, in particular a rubber material, is provided.

According to one third practical embodiment The invention proposes that in the lateral surface of the Impeller at least one reducing the diameter of the impeller circumferential grooves are formed and circulating in these Grooves the diameter of the impeller enlarging circumferential ring elements can be used. These quasi used as tires in the Einkehlungen Ring elements cause the contact between the impeller and the driven roller to be driven.

The Ring elements are preferably according to the invention designed as O-rings, in particular of a rubber material, for a good frictional connection and thus a good power transmission to ensure the carrying role.

The power transmission between the driven impeller on the one hand and the driven roller to be driven on the other hand according to the invention by continue to be improved, that the at least one driven Impeller in the direction of at least one driven roller to be driven spring loaded.

Finally will proposed with the invention that a driven impeller is in operative connection with two carrying rollers. In this way is it is possible the number of necessary wheels for Minimize drive of the idlers.

Further Features and advantages of the invention will become apparent from the accompanying drawings, in the two embodiments a drive according to the invention for one roller conveyors are shown only by way of example, without the invention to this embodiment to restrict. In the drawing shows:

1 a plan view of a conveying section of a roller conveyor with a drive according to the invention;

2 a section along the line II-II according to 1 ;

3 a side view of an impeller according to the invention according to a first embodiment;

4 a front view of the impeller according to 3 and

5 a front view of an impeller according to a second embodiment.

The illustration 1 shows one of three carrying roles 1 formed part of a roller conveyor 2 a roller conveyor. For transporting on the carrying rollers 1 lying piece goods, such as packages, along the roller conveyor 2 become the carrying roles 1 above below the idlers 1 arranged driven wheels 3 driven.

To generate the necessary friction transmission between the driven wheels for drive transmission 3 and the driven rollers to be driven 1 are in a so-called tension box 4 arranged wheels 3 in the direction of the carrying rollers 1 spring loaded biased.

As from the pictures 1 and 2 seen, are in the illustrated embodiment, the wheels 3 so to the carrying roles 1 arranged, that in each case an impeller 3 in operative connection with two carrying rollers 1 stands. By this arrangement, the number of necessary wheels can be 3 for driving the carrying rollers 1 minimize.

To avoid being driven by the wheels 3 Vibrations on the idlers 1 be transferred, the uniform transport of the piece goods along the roller conveyor 2 could hinder, is the lateral surface 5 the wheels 3 designed so that the contact surface between the driven wheels 3 and the driven rollers to be driven 1 is formed interrupted. This means that, in contrast to the usual planar contact along the entire common axial extension, this contact surface between the interacting with each other wheels 3 and carrying rollers 1 only partially formed.

In the pictures 3 to 5 are exemplary two embodiment of an impeller 3 represented, which has such a configured contact surface. As in particular from 4 visible, are on the lateral surface 5 this first wheel 3 three substantially parallel to each other and the diameter of the impeller 3 Enlarging circumferential ring areas 6 formed over which the impeller 3 with the driven roller to be driven 1 can come into operative connection.

Also off 4 it can be seen a second structural design possibility for the formation of the lateral surface 5 of the impeller 3 , after which in the lateral surface 5 of the impeller 3 at least two substantially parallel angeord designated and the diameter of the impeller 3 reducing circumferential grooves 7 are formed. This embodiment is almost the reverse of the previously described embodiment, since in this case the with the support roller 1 in contact ring areas 6 be formed by that in the lateral surface 5 of the impeller 3 circumferential grooves 7 be incorporated.

To get a good drive transfer from the impeller 3 on the carrying role 1 to ensure, is the surface of the lateral surface 5 of the impeller 3 at least in the one with the carrying role 1 in contact areas with a friction-increasing material, in particular a rubber material provided.

At the in 5 illustrated third embodiment of the impeller 3 becomes the discontinuous contact area between the impeller 3 and the carrying role 1 generated by that in the lateral surface 5 of the impeller 3 two the diameter of the impeller 3 reducing circumferential grooves 7 are formed and in these circumferential Einkehlungen 7 the diameter of the impeller 3 Enlarging circumferential ring elements 8th , For example, O-rings made of a rubber material, are used.

Such a trained drive for a roller conveyor is characterized in that this with good drive transmission and a low design effort in a substantially vibration-free drive of the support rollers 1 guaranteed
