A return roller is pivotally supported in a frame-fixed articulation region () of a belt conveyor device having a transport belt. A pivot arm () extends in a running direction (L) of the transport belt, orthogonal to a longitudinal axis () of the return roller, supporting it about the longitudinal axis. A pivot element () is spaced apart from the return roller in the running direction. A pivot bearing () is arranged on the articulation region for mounting the pivot element for a pivoting movement of the pivot arm around a pivot axis between an operating position and an nonoperating position of the return roller. A bearing surface (), in a section perpendicular to the pivot axis, is formed as an open arc, with an opening () having a center angle (φ) of less than 180°.

Device for pivotally supporting a return roller of a belt conveyor device, and belt conveyor device having such device

A conveyor belt unit () has a configuration-changing mechanism useful for switching between a ready-to-operate configuration and a not-ready-to-operate configuration. A specific embodiment uses a rotating joint element () with a thin material bridge () that defines a rotary axis. Used with a dynamic checkweigher, the conveyor belt unit has a carrier frame () and a belt body () connected to it. Rollers () are arranged at the ends in transport direction (T) and contrary to the transport direction, with a conveyor belt () tensioned across the conveyor rollers. A motor drives the conveyor belt () by means of one of the rollers (). The configuration-changing mechanism is effective between the belt body and the carrier frame.

A frame () supports a conveyor belt system with a longitudinally circulating conveyor belt. Two plate-like carrier elements (), with principal planes extending at right angles to the longitudinal direction (L) are joined by at least two distance elements ('), disposed parallel to the longitudinal direction (L). The distance elements space the two carrier elements apart. A plurality of support elements () and machine feet () support the frame on the ground. At least one of the carrier elements defines a seating area (), which is largely arranged horizontally. At least two first mechanical interface elements () run parallel to the distance elements, preferably extending over the carrier elements, and are fixed on the seating areas of the carrier elements. The frame also has at least two fixing elements (), by which the first mechanical interface elements () are fixed to the seating areas.

In a bearing arrangement for a pivot bearing (&#x2033;) of a roll, on which the conveyor belt () revolves, bearing receiving regions () of lateral bearing carriers () are configured such that they enclose the pivot bearings (&#x2033;) only partially and do not jut into the orbit of the conveyor belt (), wherein the pivot bearings (&#x2033;) are held in the bearing receiving regions () thereof by the revolving conveyor belt ().
