| 摘要 |
The present inventon relates to an angle station (3) for lateral angular displacement of an endless conveyor belt (2) in a conveyor system (1). The angle station (3) comprises a belt guide means (7) in the form of a plurality of large diameter guide rollers (4, 18) mounted in support brackets (19) on a support structure (20,21) with said rollers (18) substantially clear of the support structure (20, 21). The guide rollers (18) are generally elongate and arranged substantially normal to a substantially helical pathway Z for the belt (2) around the belt guide means. The guide rollers (18) are disposed in axially and laterally, closely spaced relation, so as to define a generally continuous support for a conveyor belt (2) in use of the angle station (3) which support is substantially non-angular in cross-section along the helical pathway Z. The present invention also provides a roller support bracket (19) for use in an angle station (3) of the invention as well as a guide roller unit comprising a guide roller (18) mounted in such a bracket (19).
