ABSTRACT:
A filter press plate shifter assembly provided with a shifter housing having a center part which passes over the filter plates and housing parts positioned adjacent opposite side rails. The housing parts are rollingly supported on rods which extend along the side rails. One housing part mounts a rotary pneumatic motor and a drive roller which drivingly engages the rod. Each housing part mounts a plate shifter unit having a pneumatic shift cylinder which is provided with relatively fixed and movable plate shifting blades. A pneumatic lift cylinder pivots the shift cylinder upwardly so that the blades project between handles of adjacent filter plates, following which the shift cylinder is energized so that the movable blade engages and shifts the endmost plate toward the open press head. A pressure sensor retracts the shift cylinder and lowers the lift cylinder, and a further pressure signal activates the drive motor to advance the housing to the next position for engagement with the next plate to begin the next plate shifting cycle.
