Abstract
A walking-beam conveyor has a horizontally extending movable beam flanked by a pair of horizontally extending fixed beams. This movable beam is subdivided into a relatively long main portion and a relatively short end portion. The entire movable beam can be reciprocated through a relatively short vertical stroke and horizontally through a horizontal stroke for stepwise displacement of a load supported on the beams. In addition the end portion can be vertically displaced through a relatively long vertical stroke for picking a load, as for instance a sheet-metal coil, up off a machine, as for instance a winding machine, and for similarly lifting up a load to be discharged onto a higher location.
Claims5
A walking-beam conveyor for conveying objects such as sheet-metal coils, said conveyor comprising:
- a pair of generally parallel horizontally extending and generally fixed beams;
- at least one horizontally extending movable beam generally parallel to and between said fixed beams and having a main portion and an end portion having respective upper sides;
- a horizontally extending support underneath said portions;
- a main carriage supporting said main portion on said support for horizontal displacement thereon;
- an end carriage independent of said main carriage and supporting said end portion for horizontal displacement on said support;
- means for horizontally reciprocating said portions of said movable beam jointly through respective predetermined horizontal strokes;
- means for vertically reciprocating said main portion;
- means operatively engaged horizontally between said end carriage and said main carriage for horizontally displacing said end portion independently of and relative to said main portion;
- and
- means for vertically displacing said end portion independently of and relative to said main portion through a predetermined vertical distance substantially greater than said vertical stroke.
