A roller shaft mount or support secures a shaft end of a conveyor roller at and between opposite sidewalls of a conveyor. The shaft support includes a mounting portion mountable to a sidewall of the conveyor and a clamping portion. The clamping portion is movably attached to the mounting portion and movable relative thereto. The shaft support receives a roller shaft at least partially therethrough. The clamping portion is movable relative to the mounting portion so as to clamp the roller shaft within the shaft support in response to movement of the clamping portion relative to the mounting portion. The clamping portion may move along a ramped surface toward and into engagement with the shaft of the roller in response to adjustment of a fastener to clamp the roller shaft within the shaft support.

A roller conveyor includes a plurality of idler rollers positioned along and between opposite sidewalls and a transverse drive system operable to rotatably drive at least some of the idler rollers of the roller conveyer. The transverse drive system includes a motorized roller positioned generally transverse to the idler rollers and a plurality of drive members drivably connected between the motorized roller and respective ones of the idler rollers. Actuation of the motorized roller drives each of the drive members, which in turn independently rotatably drive the respective idler rollers. The transverse drive system may be selectively operable to accumulate articles on one or more zones of the roller conveyor. The roller conveyor may include a right angle transfer unit operable to transfer articles in a direction generally normal to the direction of conveyance of the idler rollers.

An article sorter is made up of a web defined by a plurality of interconnected, laterally elongated, slats. An upper portion of the web defines a longitudinally extending conveying surface. Each of the slats has a generally planar upper surface forming a portion of the conveying surface. A plurality of pusher shoes travel laterally of the conveying surface to laterally displace articles on the conveying surface. A drive assembly is provided. The drive includes at least one sprocket and a motor. The motor is adapted to rotate the sprocket(s). The sprocket(s) engage the slats to propel the web.

A roller conveyor includes opposite sidewalls and at least two tandem zones. Each zone includes a plurality of idler rollers rotatably mounted at and between the opposite sidewalls, and a drive system having a motorized or directly driven roller. The driven roller is operable to drive the idler rollers via a drive member, which is positioned substantially beneath the idler rollers and in substantially continuous contact with a lower portion of at least some of the idler rollers. The driven roller may be selectively operable to provide accumulation of at least two articles in each of the zones. The roller conveyor may include a control which is operable to selectively operate the driven roller, such as in response to at least one article sensor along the roller conveyor or in response to a current sensor for sensing a current draw by the driven roller.
