Abstract
Apparatus for lifting tightly spaced bottles from cases, spreading the rows of bottles apart and placing the bottles on a bottle conveyor having spaced lanes. The apparatus includes a carriage having a plurality of elongated manifolds, each supporting rows of bottle grippers, the carriage having means for shifting the manifolds laterally with respect to each other to vary the spacing between rows of grippers.
Claims3
A lifting carriage for plural patterns of articles comprising,
- an elongated channel-shaped shroud including a flat top plate and depending lateral flanges,
- a plurality of transverse rods supported between said flanges,
- a plurality of elongated manifolds slidably mounted on said rods for lateral movement, each manifold having plural sets of grippers, each set of grippers on a manifold being spaced longitudinally from the adjacent set and aligned transversely with grippers on adjacent manifolds to provide plural patterns of grippers longitudinally spaced along said shroud,
- each said manifold having two upwardly projecting pins,
- said top plate having a transverse slot receiving each said pin,
- two cam plates mounted for longitudinal movement on said shroud and having angulated cam slots receiving said pins to effect lateral movement of said manifolds upon longitudinal movement of said cam plate,
- a longitudinally oriented piston and cylinder mounted on said shroud and connected to each said cam plate to thrust said cam plate longitudinally in one direction to spread said manifolds, and in other direction to retract said manifolds.
