  • Linear wave motion conveyor
    Patent number: 9452890
    Abstract: A linear wave motion conveyor is disclosed. A pan defines a conveying surface and a conveying direction. A linear drive mechanism is provided having an elongated thrust bar extending parallel to the conveying direction and a stator portion configured to drive the thrust bar in relation to said stator portion along the conveying direction. A base supporting the linear drive mechanism and the pan is provided. The thrust bar is fixed in relation to one of the base or the pan and the stator portion is fixed in relation to the other of the base or the pan. A controller is in operative communication with the stator portion to control driving of the thrust bar in relation to the stator portion. The controller is configured to cause the stator to drive the thrust bar in conformity with a cyclic pattern of motion along the conveying direction.
