  • Patent number: 10737887
    Abstract: A zoned roller conveyor is shown and described for moving a product between upstream and downstream ends of the conveyor. The zoned roller conveyor includes first and second side rails that are spaced from each other to define the conveyor width. A series of driven support rollers are spaced from each other within the conveyor zone. A drive motor is coupled to the support rollers such that the operation of the drive motor can be used to control the rotation of the support rollers in either a first or a second direction. A plurality of conveyor zones can be formed along the length of the conveyor frame where each conveyor zone is separately controlled by a drive motor. A motor controller is used to control the operation of each drive motor to transfer the product between conveyor zones and to control the movement of the product within each of the conveyor zones.
