  • Patent number: 11795004
    Abstract: A conveyor table transfer apparatus includes a link mechanism connects the drive member driven by a motor (drive source) and a movable member supporting the movable linear conveyor. The link mechanism has one or more degrees of freedom. The degree of freedom of the link mechanism causes the link mechanism to bend in response to a degree of parallelization between the linear-motion guide rail and the linear-motion guide rail, making it possible to suppress load to be applied to the drive member or the movable member. As a result, it becomes possible to move the movable linear conveyor smoothly without requiring precise adjustment in mounting of the drive member and the movable member on the linear-motion guide rail and the linear-motion guide rail respectively.
