Abstract
An accumulator conveyor for transporting intermittent loads is disclosed. Live carrier rollers define a transport surface. A drive belt is disposed subjacent the carrier rollers and brought into friction drive contact therewith by means of pressure rotors having eccentric axes of rotation. Load sensing devices are arranged at spaced locations along the conveyor transport surface between adjacent carrier rollers. Each rotor has a housing with a cylindrical outer wall rotatably mounted about an eccentric axis and containing a pressure roller. The cylindrical walls have angularly spaced apertures through which their pressure rollers protrude. Both of the apertures of a rotor housing are disposed on one side of the diametrical plane passing through the axis of rotation of the rotor. Stop or limit pins extend from one end of the rotors and may rotate depending on the position of notches in control slides linked to the load sensing device in order to operatively connect or disconnect the carrier rollers with the drive belt.
