Belt conveyor having a variable-length belt support

摘要

The invention relates to a device for transporting individual products (1) of, in particular, predefined dimensions in a transport direction A, wherein the device includes two upper belt segments (2, 3) adjacent to each other at a transition point (8), having variable length in the transport direction and each extending from an inner deflection (7, 8) at the transition point (6) to an outer deflection (9, 10) at the other end, wherein the two upper belt segments (2, 3) each are supported by a plurality of support means (11) spaced apart from each other in the transport direction, the distance between same changing as the length of the upper belt segments (2, 3) varies.

主权项

1. A device for conveying discrete products having a specified dimension in a transport direction (A), wherein the device comprises:
(a) two belts, each belt having an upper belt section (2, 3), each upper belt section (2, 3) having an inner end adjacent to the other upper belt section and an outer end at the end opposite to the inner end, the inner ends forming a transfer point (6) between the inner ends, (b) a pair of inner deflectors (7, 8) proximal to the transfer point (6), (c) a pair of outer deflectors (9, 10) at the outer ends, and (d) a plurality of support members (11) disposed at a distance from each other supporting the upper belt sections (2, 3), wherein the two upper belt sections (2, 3) are each supported by a plurality of support members (11) disposed at a distance from each other such that the distances change as the length of the upper belt sections (2, 3) varies, the support members (11) comprise support rollers (12) on which the one of the upper belt sections (2, 3) rests, wherein the support rollers (12) are each rotatable held on a roller carrier (13), which is guided in a guide and is displaceable in the transport direction, the roller carriers (13) of rollers (12) supporting one upper belt section (2, 3) are coupled via drivers (14), which limit the distance between any two coupled roller carriers (13) to the maximum distance and upon extension of an upper belt section (2, 3), the first roller carrier (13) closest to the inner deflector (7, 8) is the first to follow the displacement of the inner deflector (7, 8) reaching a maximum distance, while the other roller carriers (13) initially remain stationary, wherein the first roller carrier carries the second roller carrier along when the maximum distance between the first roller carrier and the second roller carrier is reached.
