  • Patent number: 6170648
    Abstract: The present invention relates to an angle station 3 for lateral angular displacement of an endless conveyor belt 2 in a conveyor system. The angle station 3 comprises a belt guide in the form of a multiplicity of guide rollers 22 mounted on a roller support. The guide rollers 22 are arranged in an axially and laterally extending array, so as to define a generally continuously curved support for a conveyor belt 2 in use of the angle station 3. The roller support comprise an elongate support member 24 provided with a plurality of roller support elements 26 mounting roller mounting members 28 which are arranged along a plurality of axially spaced substantially helical pathways C, D, E, F. The roller support elements 26 project from the elongate support member 24 and the elongate support member 24 is laterally offset and spaced from a common longitudinal axis of the helical pathways for the roller mounting members 28 so that the space radially inwards of the helical pathway is substantially unobstructed.

  • Patent number: 5421449
    Abstract: In an angle station for lateral angular displacement of an endless conveyor belt in a conveyor system, the angle station comprises a belt guide in the form of a plurality of large diameter guide rollers mounted in support brackets on a support structure with the rollers substantially clear of the support structure. The guide rollers are generally elongate and arranged substantially normal to a substantially helical pathway for the belt around the belt guide. The guide rollers are disposed in axially and laterally, closely spaced relation, so as to define a generally continuous support for a conveyor belt in use of the angle station, which support is substantially non-angular in cross-section along the helical pathway. A roller support bracket is provided for use in the angle station as well as a guide roller unit including a guide roller mounted in such bracket.
