[0004] The invention relates to a transport roller device, a transport roller device module comprising such a transport roller device, a distribution conveyor comprising at least one such transport roller device module and a rotary bearing.

[0005] A distribution conveyor is a key element in sorting and distribution systems, combining the functions of transporting and diverting goods. A distribution conveyor transports sorted goods along a predetermined conveyor path and diverts them at the appropriate points.

[0006] The essential components of a distribution conveyor include the traction element, which moves the sorted goods along the conveyor path, and the support element, on which the goods rest during transport. The support element can consist of belts, rollers, or other surfaces on which the goods rest.

[0007] In a distribution conveyor, several rollers are used, particularly in the area of ​​the discharge point. These rollers are arranged in a single plane and support the goods. By synchronously rotating the rollers around a vertical axis, the common conveying direction of the rollers can be changed, allowing the goods to be moved and discharged in the desired direction.

[0008] Synchronous movement typically requires a drive system or a mechanism with a complex design. For example, a linkage system is used to simultaneously transmit the power of a drive to the numerous rollers.

[0009] The invention is therefore based on the objective of providing components for a distribution conveyor or a distribution conveyor with a simplified and therefore cost-effective design.

[0010] The problem according to the invention is solved by a transport roller device for a distribution conveyor, comprising a transport roller and a rotary bearing for storage.

[0073] RGTH K250191W012037PTKaul Grundbesitz GmbH & Co KG 09.03.2026

[0074] 9

[0075] whose are mounted. A stationary arrangement means that the outer rings are not rotatable within the distribution conveyor. In particular, the outer rings are rigidly attached to the distribution conveyor.

[0076] Preferably, the distribution conveyor has a receiving device to which the transport roller assemblies are attached. In particular, the outer rings are attached to the receiving device. The receiving device can be a plate-shaped element with several, in particular round, through-openings within which the transport roller assemblies are arranged and attached. In particular, the transport roller assemblies extend through the through-openings, with the transport rollers being exposed on an upper surface of the receiving device and forming the support surface for the conveyed goods.

[0077] Preferably, the transport roller device module comprises the first drive element and a drive, in particular an electric motor, for driving the first drive element to transmit the torque to the inner rings.

[0078] Preferably, the drive element is designed as a closed belt or chain, wherein the drive includes a gear element by means of which the torque can be transmitted from the drive to the drive element.

[0080] The inner rings each have an engagement structure through which the torque from the first drive element can be transmitted to the inner rings.

[0082] RGTH K250191W012037PTKaul Grundbesitz GmbH & Co KG 09.03.2026

[0083] 10

[0084] Preferably, the distribution conveyor comprises at least two transport roller device modules, each of which has its own drive.

[0085] The transport roller device modules can preferably be operated in combination with each other in the distribution conveyor. This means that the transport roller device modules are arranged directly adjacent to each other, particularly along the conveying path of the distribution conveyor, and are controlled synchronously, so that both transport roller device modules are used simultaneously to distribute the conveyed goods in the same direction at a discharge point.

[0086] Preferably, the distribution conveyor comprises at least two transport roller device modules and a control unit for controlling the transport roller device modules, wherein the transport roller device modules, in particular their drives, can be controlled, especially synchronously, by means of the control unit. For this purpose, the control unit is connected, in particular, to the individual drives of the transport roller device modules. Advantageously, several transport roller device modules, in particular three, four, or more, can thus be controlled with a single control unit, which allows the system to be designed in a simple and cost-effective manner. Furthermore, it is advantageously possible to expand the system modularly by adding further transport roller device modules, which can then be connected to the existing control unit.

[0087] Furthermore, each transport roller device module can have its own control unit. If several transport roller device modules are functionally combined in a distribution conveyor, the control units are preferably configured so that the transport rollers are moved synchronously, in particular about the axis of rotation of the rotary bearing and the axis of rotation of the transport rollers.

[0088] Within the distribution conveyor, preferably all transport roller device modules have their own drive. However, it is also possible for two or more transport roller device modules to share a common drive. In this case, the common drive comprises several gear elements.

[0089] RGTH K250191W012037PTKaul Grundbesitz GmbH & Co KG 09.03.2026

[0090] 11

[0091] Each of the transport roller device modules is connected to a gear element. Thus, torque can be transmitted to the drive elements, particularly synchronously, via the gear elements.

[0092] Furthermore, the multiple transport roller device modules can be controlled by their own or a common control unit in such a way that the transport roller device modules discharge transported goods in different directions.

[0093] Preferably, several transport roller device modules are provided, for example two, three, four, five, six or more transport roller device modules.

[0094] Preferably, the transport roller device modules can be arranged one behind the other and / or side by side in a main transport direction or along a conveying path of the distribution conveyor. In other words, the transport roller device modules form zones that can independently discharge transported goods, particularly essentially simultaneously, in different directions. This allows groups of transported goods placed on the distribution conveyor to be depalletized or layer patterns to be broken down. This is achieved by arranging the individual transported goods on different transport roller device modules or zones, and thus allowing the transported goods within the group to be moved in different directions by appropriately controlling the transport roller device modules. This allows, for example, the following:The transported goods are moved in different directions from the conveyor belt and thus discharged to different sides. Furthermore, the transport roller device modules can move the goods only to the point where they are spaced further apart and simply separated. This application is possible in conjunction with a distribution conveyor. The transport roller device modules can therefore also be combined to form a depalletizing module, a separation module, or a combination of both, and used together with a distribution conveyor or independently as a separate system. In particular, layer patterns can be resolved by appropriately controlling the transport roller device modules.

[0095] RGTH K250191W012037PTKaul Grundbesitz GmbH & Co KG 09.03.2026

[0096] 12

[0097] For example, a series of cartons, say four, can be transferred from a pallet onto the distribution conveyor and the transport roller modules. The cartons are positioned so that they rest on different transport roller modules. Through the previously described control of the transport roller modules, the cartons can be moved in different directions, thus disentangling the row or layer pattern.

[0098] The conveying of the goods by the individual transport roller device modules in different directions independently of one another can preferably take place in a forward direction, in a reverse direction, and / or laterally to the left or right. A radial arrangement of the transport roller device modules is also conceivable, such that the goods are moved radially outwards from a central point in different directions.

[0099] Preferably, the distribution conveyor has a second drive unit for driving the transport rollers. Preferably, the second drive unit comprises drive rollers or drive drums that drive the aforementioned second drive element of each transport roller. For this purpose, the second drive element is clamped around the transport roller and the drive roller, so that a rotation of the drive roller transmits a torque to the transport rollers via a frictional connection between the second drive element and the transport rollers or the drive roller. A second drive, for example an electric motor, is provided for driving the second drive unit.

[0100] Preferably, the second drive elements of several transport roller devices are connected to a second drive unit. Preferably, several transport roller devices are arranged in a row in the distribution conveyor, with a drive roller extending parallel to the row of transport roller devices below the row. The second drive elements extend downwards towards the transport roller and are connected to it.

[0101] Since the second drive elements are flexibly designed, torque transmission is still possible even when the transport rollers move together with the

[0102] RGTH K250191W012037PTKaul Grundbesitz GmbH & Co KG 09.03.2026

[0103] 13

[0104] Rotate the inner ring around the axis of rotation of the rotary bearing. The drive elements are then twisted and lie on top of each other in a central area. Torque transmission is still possible.

[0105] Furthermore, the problem according to the invention is solved by a rotary bearing, in particular a rotary bearing of a transport roller device according to one of the embodiments described above, comprising an outer ring and an inner ring rotatable relative to the outer ring, wherein the inner ring is designed for connection with a flexible first drive element such that a torque can be transmitted from the drive element to the inner ring, wherein the inner ring has a connecting section, in particular a connecting skirt, via which the inner ring can be connected to the first drive element for transmitting the torque, wherein the connecting section has an engagement structure, preferably a toothed ring, for force-fit connection with the first drive element, and wherein the connecting section projects beyond the outer ring in the direction of the axis of rotation of the rotary bearing at least on one side of the rotary bearing.

The first drive element 14 is a toothed belt, which is driven by a first drive 14a to transmit the torque from the first drive 14a via the pivot bearings 10 to the transport rollers 11.

[0120] In addition to rotating about the axis of rotation of the pivot bearings 10, the transport rollers 11 are also rotatable about their longitudinal axis or bearing axis for distributing the transported goods. For this purpose, each transport roller 11 is connected to a second drive unit 15a via a second drive element 15. The second drive unit 15a is, in particular, a drive roller or drive drum, and the second drive element is a closed drive cable that is tensioned around the transport rollers 11 and the drive roller.

[0137] formed by the individual transport rollers 11 of the individual transport roller devices 100 of the transport roller device modules 200.

[0138] The transport roller device modules 200 each have their own drive 14a and can therefore be driven independently of one another. The drives 14a are connected to a common control unit 21. The drives 14a can be controlled synchronously via the control unit 21, so that the transport rollers 11 can be rotated synchronously, meaning always at the same angle and speed around the axis of rotation D. Alternatively, it is also conceivable that each transport roller device module 200 or each drive 14a has its own control unit 21, which are configured accordingly so that the transport rollers 11 are moved synchronously.
