  • Patent number: 8388298
    Abstract: A load positioning apparatus includes a movable table that is urged and held at a forward limit position by a movable-table urging element, a load-supporting roller that allows the load to laterally move on a horizontal surface, and a load-positioning roller that is supported on the movable table and adjoins the side face of the load supported in the fixed position on the load supporting roller. The urging element allows the table to recede together with the load-positioning roller when a load is vertically lowered at a position where the load-positioning roller is pushed outwardly with respect to the fixed position. The urging element has an urging force sufficient to return the movable table to the forward limit position so as to push back the load to the fixed position via the load positioning roller.

  • Patent number: 7344350
    Abstract: The invention discloses a transporting apparatus that transmits a drive force to a transported object in a state where the transported object is supported by a air-supplying-type support apparatus. In one implementation thereof, a device for transferring drive force to a transported object transfers drive force to one side in the width direction, which is perpendicular to the transporting direction. In another implementation thereof, the transporting apparatus can be switched between a horizontal state in which the transported object is supported substantially horizontally, and an upright state.

  • Patent number: 7329299
    Abstract: It is an object of the present invention to provide a plate-shaped work piece transporting apparatus that has a fan, a dust-removal filter disposed above this fan, and a plate-shape porous member disposed above the dust-removal filter. By forming a chamber in which air can accumulate between the porous member and the dust-removal filter, it is possible to suppress air pulsations. Further, by providing support members on the porous member, the plate-shaped work piece can be supported and damage thereto can be avoided when the plate-shaped work piece, which is supported by air from the fan, drops to below a set height.

  • Patent number: 7004711
    Abstract: The invention discloses a transporting apparatus having a transport member provided with a air-supplying-type support portion for supplying purified air toward a lower surface of a transported object to contactlessly support the transported object, and a drive force application portion for contacting a lower surface of the transported object that is supported by the air-supplying-type support means and applying a drive force in the transporting direction to the transported object. The transporting apparatus, by raising and lowering the drive force application portion and the air-supplying-type support portion relative to one another, can be switched between a transport state where the drive force application portion is brought into contact with the lower surface of the transported object, and a transfer state where the drive force application portion is moved downward away from the transported object that is supported by the air-supplying-type support portion.
