Abstract:
1. An adjustable conveyor guide rail unit adapted for use in a conveyor guide to define the side of a channel through which an article may be conveyed, the guide rail unit comprising: a fixed-position support; a carriage operable to carry a guide member; and a position-setting mechanism comprising a shaft extending in a direction that is not parallel with a width of the channel and a rotatable part mounted on the shaft; wherein: the carriage is coupled moveably to the fixed-position support via a position-setting mechanism, such that the carriage and hence guide member are moveable relative to the fixed-position support to allow the guide member to be placed in a plurality of discrete positions to allow the width of the channel to be varied; the position-setting mechanism is arranged to set the carriage and hence the guide member into a selected one of the plurality of discrete positions using a complementary pin and hole arrangement where a pin is received in a hole, and wherein the rotatable part is movably mounted on the shaft such that the rotatable part may be moved along the shaft from a closed position in which a pin is received within a hole thereby setting a position of the guide member, to an open position in which there is no engagement between a pin and a hole thereby allowing the carriage to move relative to the fixed-position support.
