Abstract
A conveyor includes a frame and at least one moving mechanism which can be moved in a longitudinal direction thereof by a driving mechanism. Carriers extending transversely to the direction of movement of the moving mechanism are coupled to the moving mechanism. At least a few of the carriers support sliding pieces, which can be moved along the respective carriers by guide mechanisms, so as to move objects to be conveyed by the conveyor during operation. A carrier is coupled to the moving mechanism near its center, which moving mechanism includes links, which are pivotable with respect to each other about pivot pins crossing or intersecting each other at least substantially perpendicularly.
Claims8
A conveyor which comprises:
- a frame;
- a single moving means having a plurality of links which are pivotable with respect to each other about pivot axes crossing or intersecting each other at least substantially perpendicularly;
- driving means for driving the moving means in a longitudinal direction;
- a plurality of carriers which have beams extending transversely to the direction of movement of the moving means;
- a plurality of supports extending upwardly from said moving means, wherein the supports are respectively coupled to the beams in proximity with a center portion of the beams and are connected to said links of the moving means;
- a plurality of sliding pieces respectively supported by the beams so as to be slidably movable to and from along the beams and displacing objects to be conveyed by the conveyor during a conveying operation;
- guide wheels respectively directly mounted on the sliding pieces;
- guide rails which extend transversely to a direction of movement of the moving means;
- and
- switch pieces arranged in a switch station such that the guide wheels are guided in a direction of said guide rails by engagement of said guide wheels with said switch pieces wherein said switch pieces are pivotable into and out of a path of movement of the guide wheels.
