ABSTRACT:
A pneumatically actuated, beltless conveyor assembly includes a housing, a drive system supported by the housing and at least one transport tray supported by the housing and operatively connected to the drive system. The drive system includes a seal-less pneumatic engine having at least one pair of opposed, pneumatic drive bellow assemblies. One of the drive bellow assemblies acts to drive the transport tray in one direction at a first predetermined speed to advance materials supported on the transport tray in the direction of the length of the tray. The other of the pair of drive bellow assemblies acts to drive the transport tray in a second direction opposite to the first direction and at a second, predetermined speed that is different from the first predetermined speed such that the transport tray moves relative to the material supported thereon.
