  • Patent number: 9114936
    Abstract: A conveyor apparatus includes a pusher piece (19) fixed to a conveying rod (18) adapted to reciprocate along a board conveyance path, and a switching mechanism adapted to switch the pushing piece, by turning the conveying rod a predetermined angle, between an engaged position where the pusher piece (19) engages with a rear end face of a board (7) and a retracted position where the pusher piece (19) does not interfere with the board (7). The switching mechanism includes a guide member (23) provided with a guide hole (24) adapted to guide a guide rod (22). The guide hole (24) is made up of first and second guide holes (25 and 26) configured to extend in parallel to each other in a conveyance direction and slanted coupling guide holes (27, 27) adapted to couple ends of the first and second guide holes (25 and 26). When the conveying rod (18) reciprocates, the guide rod (22) makes a round of the closed-loop guide hole (24).

  • Patent number: 7299912
    Abstract: A conveyor system for transporting a work piece from a beginning point to an end point in a longitudinal direction with at least one process step applied in between to such work piece is provided according to the invention. The work piece is propelled in the longitudinal direction over a combination of grooved rollers and conveyor belt units in series. Grooved guide means with, e.g., V, U, or square shapes that are machined into the surface of the rollers prevent the work piece from moving laterally as it is transported in the longitudinal direction, and maintain precise spacing between a plurality of work piece strands undergoing simultaneous transport by the conveyor system. The conveyor belt unit located between the grooved rollers inhibits rotation of the work piece as it is transported in the longitudinal direction. This conveyor system is good for treating the entire exterior surface area of the work piece in a uniform manner, such as coating the surface of rebar, dowel bar, hollow tube, or pipe.
