Abstract:
A slat conveyor comprising at least one lifting slat having a down position, an up position and a top;a fixed position lifting ramp below the top of said lifting slat, said lifting ramp having an upper surface that slopes upwardly from a low end to a high end; a lifting block positioned on the lifting ramp, vertically between the lifting ramp and the top of the lifting slat, said lifting block having a sloping bottom surface corresponding in slope to the top surface of the lifting ramp, and having a top surface that is substantially parallel to the top of the lifting slat when the sloping bottom surface of the lifting block is on the sloping top surface of the lifting ramp; and a longitudinally reciprocating drive member having at least one abutment that is movable against the lifting block as the drive member moves in a first direction, for forcing the lifting block up the lifting ramp, so as to cause the lifting block to push upwardly on the lifting slat and move it upwardly into its up position, and also having at least one other abutment that when the drive member is reversed is movable against the lifting block for forcing the lifting block down the lifting ramp, allowing the lifting slat to drop downwardly into its down position.
