The invention relates to a role for accumulating roller conveyors with dsren help the conveyed goods temporarily for longer or for a shorter period of time and jammed in the course of the conveying process is further conveyed again, the rollers are driven continuously. Bsi a well-known Accumulation roller conveyor for heavier goods is activated with the help of several rotors, switching rollers, limit switches, rod locks and various linkages cause the goods to be stowed and started up again «. This execution is complex and expensive because of the large number of parts required. The same goes for another Accumulation roller conveyor, the rollers of which are driven by a profiled belt via slip clutches. the Couplings are actuated and switched via cable pulls by the conveyed goods approaching the swivel flags the roles off. Springs in the clutches switch them on again when the conveyed goods swivel has overflowed. The present invention avoids these disadvantages and the production an accumulation roller conveyor is simplified.

According to the invention, a roller is made of circular and rotatable on a square or round shaft small rollers arranged between round disks connected with each other, which hold the disks tower above. To reduce the polygon effect, the small rolls between two slices alternately offset by half their pitch »near a preferred Embodiment are made up of two disks each and then small rollers rotatably mounted between them

ELn: eleIeniBnfci3 formed on a square üJella with a stop at one end and Thread for a screw nut at the other end in larger depending on the width of the roll to be formed or a smaller number have been postponed. The cut-outs for receiving the washers on the square shaft correspond to the shape of an eight-pointed star, so that the individual elements are pushed onto the üJells can be that the small roles are offset from one element to the other. the

W axes of the small rollers are in the disks with

Plain bearings stored, the flanges of which are designed as friction surfaces for the end faces of the small rollers are. . With the help of the screw nut on the shaft, pressure on the washers reduces the friction between the flanges of the plain bearings and the faces of the small rollers so that on the one hand the entrainment of the conveyed goods when the roller is turning by the small ones, as a result of the friction on the light ones

k turning hindered roles is guaranteed, on the other hand the small rollers with jammed conveyed goods during the rotation of the roller are under the conveyed goods can turn. When the traffic jam is resolved, the role works again as a normal driven roller conveyor roller and moves the conveyed goods waiter.

In a further embodiment, the small roles between ζωβϊ are firmly connected to a round wall round discs rotatably supported by ijriri

a cylindrical casing surrounded, which is protected by externally mounted to the round discs lids against axial displacement * The small rolls are supported inside a ring from _s of loosely rotatably provided on the round shaft and ujird held by spacer sleeves in its central position. The friction pressure achieved between the ring and the small rollers on the one hand and the small rollers and the inner surface of the cylindrical jacket on the other hand, through the dimensioning of these parts, causes all roller parts to rotate in the same direction and thus the role of the roller as a normal driven roller conveyor roller, on the other hand When the roller is not under load due to the stowage of the material being conveyed and the resulting pressure on the cylindrical casing, its standstill, furniture roll off the small ratchets that continue to rotate on the inner surface of the casing. The inner ring is rotated on the shaft.

For roller conveyor curves conical friction rollers are formed by applying cones onto the cylindrical jackets of the lined-up on the shaft individual elements, wherein the diameters of the cones from the Innsn- = radius of the curve are against their outer radius to gsößss.

A particularly simple embodiment that is particularly suitable for conveying and stowing lighter goods, arises from the use of rollers and discs

When assembling the roller for the accumulation roller conveyor, the small rollers are installed offset from one another in sections * The small plastic rollers either have continuous steel axles or bores at the ends with which they rotate on pins inserted in the discs. Small rollers made of tubular steel run either with ball bearings fc on axles firmly clamped between the discs
