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 receiving bin for a sorting machine is movable between an operative configuration and an inoperative configuration. In the operative configuration, the receiving bin is configurable for receiving a rejected product from the sorting machine. In an inoperative configuration, the receiving bin is configurable for servicing and maintenance. The receiving bin has an inlet chute, a transfer chute, and, optionally, a mechanism of altering the configuration connects the inlet chute and the transfer chute. In one arrangement, the inlet chute and the transfer chute are sufficiently exposed to a waterjet during a cleaning event, for maintaining aseptic conditions and a hygienic environment. This is especially useful the sorting machine is commissioned in a production plant where food items such as meat, fish, or dairy products are processed and packaged.

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.

Abstract: A frame (1, 101, 201) supports a conveyor belt system with a longitudinally circulating conveyor belt. Two plate-like carrier elements (2, 102), with principal planes extending at right angles to the longitudinal direction (L) are joined by at least two distance elements (4, 4?), disposed parallel to the longitudinal direction (L). The distance elements space the two carrier elements apart. A plurality of support elements (5) and machine feet (21) support the frame on the ground. At least one of the carrier elements defines a seating area (3), which is largely arranged horizontally. At least two first mechanical interface elements (6) 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 (7), by which the first mechanical interface elements (6) are fixed to the seating areas.

Abstract: A belt conveyor (1) includes a conveyor bed (6) on which belt rollers (13, 14) are arranged, respectively, at both the leading end and the trailing end relative to the transport direction T, and it also includes a conveyor belt (5) which is arranged to be movable over the conveyor bed (6, 106) and around the belt rollers (13, 14). The conveyor belt (5) is arranged and pulled tight over the conveyor bed (6) and the belt rollers (13, 14) in such a way that a sealing effect is achieved between the outside borders (7) of the conveyor belt (5) and the conveyor bed (6), wherein the outside borders (7) of the conveyor belt (5) are set back from the edges (16) of the conveyor bed (6) by a distance (d) equal to at least the maximum sweep of a lateral variation in the movement of the conveyor belt.

Abstract: A combined weighing/metal-detection system comprises at least one support frame and at least two weighing cells arranged at mounting locations on the at least one support frame. A conveyor device rests on the weighing cells. The system further includes a metal detector with a passage opening, wherein the conveyor device passes through the opening. The at least two weighing cells are arranged, respectively, on opposite sides of the metal detector, preferably close to the upstream and downstream ends of the conveyor device. The metal detector is supported on the at least one support frame at mounting locations different from the mounting locations of the weighing cells, so that the weighing cells are not carrying the pre-load of the metal detector and the two functions of weighing and of detecting metallic contaminants can occur on the same at least one conveyor device close together in time.

Abstract: The invention relates to a check weigher for weighing products during the transport thereof on a weighing belt (2) supported on a weighing cell (7). According to the invention, the parasitic oscillations occurring as products arrive on the weighing belt are suppressed by an initial load (V) applied to the weighing cell (7). The pressure exerted by the initial load is temporarily lifted for the detection of the weight measuring values.
