Abstract
Method and apparatus for feeding sand molds laterally and/o between stations of differing heights. The method and apparatus of this invention utilize walking-beam-type conveyors having spaced apart fixed outboard rails and a central reciprocating rail. Walking-beam conveyors can be disposed in perpendicular directions with a junction therebetween that allows for a perpendicular change in direction. The method and apparatus of this invention include lift, leveling, and/or lateral transfer mechanisms for lateral placement of the stations relative to the conveyance path.

An apparatus for conveying a sand mold, the apparatus comprising:
- an accumulating conveyor including a transfer rail movable with respect to at least one fixed rail, wherein the accumulating conveyor comprises an adjustment mechanism in combination with the transfer rail, the adjustment mechanism configured to adjust a horizontal alignment of the transfer rail with respect to the at least one fixed rail;
- and
- a device for moving the sand mold onto and/or off of the accumulating conveyor in a direction lateral to a conveying direction of the accumulating conveyor and/or at different vertical heights.
An apparatus for conveying a sand mold, the apparatus comprising:
- an accumulating conveyor including a transfer rail movable with respect to at least one fixed rail;
- and
- a transfer station at a downstream end of the accumulating conveyor, the transfer station including a mold lift platform and a pusher, wherein the mold lift platform is configured to raise the sand mold off the at least one fixed rail into a position adjacent the pusher.
