Support roller for a roller conveyor

The invention relates to a support roller for a roller conveyor, in particular an accumulation roller conveyor, with double fixed, driven axle and a jacket sleeve surrounding it.

An accumulation roller conveyor is about conveying goods that have been checked in at irregular intervals Bring jams evenly spaced. So far, this has been achieved, for example, by brake gears, brake a roller or groups of rollers, so that the material that hits them on the roller conveyor is not conveyed further or only very slowly. Another known way of achieving one

Traffic jam consists in the one triggered by a switch Shutdown of the drive of individual idlers. Both arrangements require a disproportionately high constructive effort through which the creation of such systems and their operation become more expensive and the iiire St «r» nr «l) .i5W-f» it increased. Incidentally, is with such Accumulation conveyors of the energy required by the intermediate brake gear or frequently successive ones Starting the drive quite large.

Another disadvantage of the fact that the drive itself always influences to achieve a traffic jam has to be, lies in a certain time delay in the start-up of the rollers, which despite the jam process Desired continuity of the material flow is impaired.

There are also chain conveyors with two chain strands. On the chain strands arranged parallel to one another freely rotating rollers are mounted that carry the conveyed goods. When the chain rotates, the stationary ones become Rolls and with them also the conveyed goods. If you now stop the conveyed goods by means of a stop, they turn the rollers run in the opposite direction to the conveying direction and roll away under the conveyed goods. The design effort is with this The system is very large and the dimensions are uneconomical according to the effect.

The object of the invention is to provide an accumulation roller conveyor without brake gears or similar expensive components to train that it is robust and works reliably and satisfactorily practically maintenance-free.

This object is achieved in that the double-mounted, driven axle of the support roller at least in the area of their ends by sliding bushings

with play is passed through that with which the axis surrounding jacket sleeve are rotatably connected. The carrier rollers are taken along via sliding friction. this means that the drive during the stopping of the outer one caused by the goods to be stowed itself Roll shell continues and remains completely unaffected by the jam process. Gears, switches and similar drive transmission means or control elements can be omitted, whereby the structure of the accumulating roller conveyor according to the invention is very simple and inexpensive can be made worthy. The propulsion force and thus also the dynamic pressure can be determined by a suitable choice largely adapt the diameter of the bore of the sliding bush to the requirements of the material to be conveyed. the The relationship between the bore diameter and the dynamic pressure is that the dynamic pressure increases with the size of the Bushing bore increases because the lever arm becomes smaller from the center of the axle to the upper edge of the roller. aside from that A reduction in speed is achieved through the difference in circumference between the axis and the bore.

This already reduces the distance between two successive conveyed goods from the stop, as a result of which the pure traffic jam time is shortened.

The jam effect is achieved in that the first conveyor piece is stopped by means of a stop device is accumulated until the following conveyed goods are accumulated in the desired manner. The drive runs during the The jam continues unchanged - the idlers themselves stand still. To end the jam process, the Stop is removed, the idlers are taken along by the axle via sliding friction and the goods can be transported in be transported further at regular intervals.

The arrangement according to the invention can be straight

as well as on curved conveyor lines.

In an embodiment of the invention, the sliding bushing can be connected non-rotatably to an annular body surrounding it be who in turn carries the jacket sleeve. The twist-test connection between the sliding bush and the ring body can be easily made so that the sliding bush can easily be removed from the ring body and against a Guide bushing is interchangeable with a different bore diameter.

And sliding bush ring body may be used for cost savings from different materials, in particular plastics of different hardness are made, with only the Eq ^ ^ bush made of slippery and therefore more expensive material j se. If you ignore the cost factor, the. ./On omitted and the sliding bush directly connected to the jacket ^ tllse of the roller in a rotationally fixed manner =

The drawing shows an exemplary embodiment of the invention shown schematically.

The only figure shows a support roller with the sliding bush according to the invention partially cut.

The support roller 1 consists essentially of a driven axle 2, which at both ends via conventional Camp 4 stored in frame parts 5 and over the largest Part of its length is surrounded by a jacket sleeve 3. The "n" of a housing of the frame is used to drive the axis 2 5 housed double chain rea 6 of a chain drive.

In the area of the idler roller ends, the axle 2 is passed through a sliding bush 7 each, which is made of slippery Material consists and is non-rotatably connected to an annular body 8 surrounding it, e.g. by a press fit

which the jacket sleeve 3 is applied displacement-proof. The ring body 8 can expediently be made of a harder material be made as the ring socket 7.

According to the invention, the drive axle 2 has a certain play 9 »its size in relation to the bore of the sliding bush 7 the conveyed material 10 lying on the support roller 1 caused dynamic pressure determined. The larger the game 9, the smaller the lever ρ and the larger it becomes the dynamic pressure or the propulsion force.

The sliding bush 7 is secured against axial displacement in that it faces inwards on one side directed flanges because the ring body 6 rests and on the other side of one in the ring body 6 latching Labyrinth seal 11 is held.
