A drive roller assembly for a conveyor system includes a drive roller having a longitudinal axis, the drive roller having a roller body and a shaft. A support structure rotatably supports a second axial end portion of the shaft and a drive for rotatably driving the drive roller. A first axial end portion of the shaft and the drive are rotatably coupled in an axially engaged condition in which the drive roller is in rotatable engagement with the drive and in which the drive is axially releasable. The support is configured and adapted to be detachably attached to an attachment portion of the support structure to maintain the drive roller rotatably supported when attached and to allow the drive roller to be removed from the support structure when detached.

A hygienic magnetic tray and conveyor. The low-profile tray includes a forcer sandwiched between an article-supporting top and an opposite bottom. The top is made of hygienic material, and the bottom can be made of a low-friction material. The tray is propelled along a guide surface on an enclosure housing stator coils supported in a conveyor frame. The stator forms a linear motor with the forcer in the tray. Roller balls protruding from the bottom of one version of the tray provide low-friction rolling contact with the guide surface. Various disposal systems provide escape routes for removing fluids and debris from the guide surface of the stator enclosure.

A conveyor roller turn for establishing a curved path for a conveyor chain includes a frame supporting a rail defining a curved conveyor path, and a roller body supported rotatably on the frame along the curved conveyor path. The roller body has an outside surface positioned to provide horizontal support to the conveyor drive chain. At least one bearing supports the roller body on the frame, the at least one bearing including: a plurality of ceramic rolling elements, an inner race supporting the plurality of ceramic rolling elements on a radial inner side of the bearing, an outer race supporting the plurality of ceramic rolling elements on a radial outer side of the bearing, and tungsten disulfide dry film lubricant on the ceramic rolling elements.

A folding wing for a conveyor is disclosed that can extend to facilitate sorting of items and providing additional space for docking locations. A first and second section each have a conveyor surface; and are coupled with a reverse-knee joint such that, in a folded configuration the conveyor surface of the first section and the conveyor surface of the second section are adjacent, and in an unfolded configuration, the first section conveyor surface and the second section conveyor surface form a contiguous conveyor surface. In some examples, the frame may be made of aluminum, and the rollers made of PVC, in order to reduce weight. In some examples, the folding section may measure approximately two feet by two feet. The folding assembly may drop down for even more space savings, when not in use, and be supported in an extended configuration with a second reverse knee joint.

A locking device for locking a wheel track (30) of a carton flow bed rack to an end beam (10; 20) of the carton flow bed rack in a mounting position includes a locking plate (50) for connecting the wheel track (30) to the end beam (10; 20) and a cover rail (40) for fixing the locking plate (50) to the wheel track (30). The locking plate (50) has a mounting end (51) configured to engage the end beam (10; 20) in the mounting position. The locking plate (50) further has an elongated protrusion (52) configured to protrude out of the end beam (10; 20) in the mounting position. The cover rail (40) is configured to encase at least partially both the protrusion (52) of the locking plate (50) and an end section of the wheel track (30) in the mounting position.

A skate wheel conveyor system includes a pair of frame sides of a frame assembly. A plurality of preassembled rollers is received between the pair of frame members. Each of the rollers includes a plurality of wheels interposed between a plurality of spacers and a shaft receiving the plurality of wheels and the plurality of spacers. A quick assembly system retains the rollers between the pair of frame members and minimizing deflections of the preassembled rollers.
