Abstract
A power driven conveyor having a drive means and a carrier supported for movement along a path of travel parallel to the path of movement provided by the drive means. The carrier has a contact surface adjacent to the drive means that is movable between a first position wherein the contact surface is disengaged from the drive means and a second position wherein the contact surface is frictionally driven by the drive means so as to cause the carrier to move from a first station to a second station along the path of travel provided by the drive means. An actuator is operatively associated with the carrier for causing the contact surface to move between the first position and the second position.
Claims26
A power driven conveyor having a drive means, a carrier supported for movement along a path of travel parallel to the path of movement provided by said drive means, said carrier having a contact surface adjacent to said drive means that is movable between a first position wherein said contact surface is disengaged from said drive means and a second position wherein said contact surface is frictionally driven by said movable drive means so as to cause said carrier to move along said path of travel provided by said drive means, and an actuator operatively associated with said carrier for causing said contact surface to move between said first position and said second position.
A power driven conveyor having a continuous movable drive means, a carrier supported for movement along a path parallel to the path of movement of said drive means, said carrier having a contact surface adjacent to said drive means that is movable between a first position wherein said surface is spaced from said movable drive means and a second position wherein said contact surface frictionally engages said movable drive means so as to cause said carrier to move relative to said drive means along the path of travel of said movable drive means, and an actuator forming a part of said carrier for moving said contact surface between said first position and said second position.
A power driven conveyor having a plurality of rotatable and pivotably supported pinch rollers providing a path of travel for a load supporting carrier, said carrier having a contact surface adjacent to said pinch rollers that is movable between a first position wherein said contact surface is spaced from said pinch rollers and a second position wherein said surface successively frictionally engages said pinch rollers to provide drive thereto so that said carrier is moved along said path of travel of provided by said pinch rollers, and an actuator connected to said carrier for moving said contact surface of said carrier between said first position and said second position.
