US 6,318,048 B1 · Case sealer mast and trolley assembly

Abstract

A mast and trolley assembly for a case sealer machine includes a set of fixed bearing members mounted upon the trolley assembly, and a set of movably adjustable bearing members mounted upon the trolley assembly such that opposite sides of the trolley assembly will engage the mast member with the proper degree of tension whereby adjustable vertical movements of the trolley assembly along the mast member are smoothly accomplished without any play or chatter. The machine head assembly is also bolted to the trolley assembly such that replacement or exchange of different sized head assemblies are readily, easily, and quickly achieved. A coiled spring mechanism is mounted upon the mast member and operatively attached to the trolley assembly so as to counterbalance the weight of the trolley and head assemblies thereby rendering the vertical adjustments of the head and trolley assemblies along the mast member easy to achieve in a counterbalanced manner. A mast guard, a mast cap, a spring guard, and a trolley guard enclose the various operative components of the machine so as to eliminate safety hazards for operator personnel.

Dependent claims

A mast and trolley assembly for use in connection with a machine, comprising:

a vertically upstanding mast member;
a head assembly having components thereon for performing an operative function upon a product to be processed by the machine;
a trolley assembly having said head assembly affixed thereon and having a polygonal configuration so as to be mounted upon said vertically upstanding mast member in a surrounding manner for movement along said mast member between different vertical elevational positions;
first means mounted upon said trolley assembly for adjustably engaging at least one external surface of said mast member with varying degrees of force such that said trolley assembly is movable along said mast member in a stable manner between said different vertical elevational positions in a relatively smooth manner without any excessive play and chatter defined between said mast member and said trolley assembly;
and
second means mounted upon said trolley assembly for lockingly engaging said mast member so as to fix said trolley assembly at a particular elevational position along said mast member when said trolley assembly has been moved from a first one of said different vertical elevational positions to a second one of said different vertical elevational positions.
