Abstract: A return roller is pivotally supported in a frame-fixed articulation region (20, 21) of a belt conveyor device having a transport belt. A pivot arm (30, 31) extends in a running direction (L) of the transport belt, orthogonal to a longitudinal axis (12) of the return roller, supporting it about the longitudinal axis. A pivot element (40) is spaced apart from the return roller in the running direction. A pivot bearing (22, 23) 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 (24, 25), in a section perpendicular to the pivot axis, is formed as an open arc, with an opening (26, 27) having a center angle (?) of less than 180°.

Abstract: A conveyor belt unit (100) 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 (150) with a thin material bridge (152) that defines a rotary axis. Used with a dynamic checkweigher, the conveyor belt unit has a carrier frame (110) and a belt body (130) connected to it. Rollers (132, 134) are arranged at the ends in transport direction (T) and contrary to the transport direction, with a conveyor belt (136) tensioned across the conveyor rollers. A motor drives the conveyor belt (136) by means of one of the rollers (132, 134). The configuration-changing mechanism is effective between the belt body and the carrier frame.

Abstract: A bin (101, 201, 301) that holds articles sorted out by a sorter has an inlet opening (102, 202, 302) for delivering the articles to an interior of the bin and a discharge device (103, 203, 303) for removing the articles therefrom, the discharge device being normally arranged below the inlet opening. The discharge device has a flap (104, 204, 304), pivotally supported for rotation about an axis (105, 205, 305), as well as two sidewalls (106, 206, 306), attached laterally to the flap. The bin includes a motion-guiding arrangement in which a guide track (107, 207, 307) and a pin (108, 208, 308) are arranged for complementary engagement in an operating state of the bin. Either the pin or the guide track is arranged on one of the sidewalls, with the other part arranged on a side of the bin.
