Abstract
A pneumatically actuated, beltless conveyor assembly includes a housing, a drive system supported by the housing and a transport tray also operatively supported by the housing. A drive system includes a seal-less pneumatic engine which acts to drive the transport tray in repeated, rectilinear fashion to advance materials supported on the transport tray in the direction of the length of the tray.
Claims11
A pneumatically actuated, beltless conveyor assembly comprising:
- a housing, a drive system supported by said housing and at least one transport tray supported by said housing and operatively connected to said drive system, said housing including a bottom plate, a slider top plate operatively connected to said drive system with said transport tray operatively connected to said slider top plate;
- said drive system including a seal-less pneumatic engine, and a control valve operating to sequentially cycle pressurized air to alternating ends of said seal-less pneumatic engine so as to drive said transport tray in repeated, rectilinear fashion through movement in one direction at a first predetermined slower speed to advance materials supported on said transport tray in the direction of the length of said tray and movement in a second direction opposite to said first direction at a second predetermined speed that is greater than the first predetermined speed such that the transport tray moves relative to the material supported thereon.
