Abstract
A slip roller conveyor utilizes slip rollers constructed of an interior sleeve formed of a relatively lower friction material combined with an exterior sleeve formed of a relatively more durable material that has relatively greater resistance to damage or wear, e.g., as may be caused by barrels or other abrasive objects to be conveyed.
Claims15
A roller conveyor for barrels comprising:
- a frame;
- a plurality of roller assemblies, and wherein each of the plurality of roller assemblies include a driven rollers arranged for conveyance of a barrel supported by the frame;
- a conveyor drive configured to rotate each of the driven rollers;
- and
- wherein each of the roller assemblies further include a slip rollers circumscribing the driven rollers, each slip roller including an exterior sleeve having a durable exterior surface and configured to slip in rotation relative to the driven rollers circumscribed by the slip roller in response to an obstructing force on a barrel supported by the slip roller, and wherein each of the plurality of roller assemblies include a first end and a second, opposite end, and the first end defines a first diameter equal to a diameter of said second, opposite end, and said first diameter is less than a second diameter of said slip roller;
- one or more end pieces, each end piece having a plurality of openings sized and configured to receive the first diameter of said first and second ends and sized to not receive the second diameter of said slip roller thereby limiting transverse movement of the slip roller;
- and,
- wherein the slip roller further includes an interior sleeve having an inner diameter that is greater than an outer diameter of the driven roller defining a spacing therebetween.

A slip roller configured to circumscribe a driven roller of a roller conveyor, the slip roller comprising:
- an interior sleeve comprised of a first material;
- an exterior sleeve comprised of a second material;
- wherein an inner diameter of the interior sleeve is greater than an outer diameter of the driven roller defining a spacing therebetween;
- wherein the roller conveyer includes one or more end pieces, each end piece having a plurality of openings sized and configured to receive ends of the driven roller and sized so that the slip roller cannot pass through the openings;
- and
- wherein the slip roller is configured to slip in rotation relative to the driven roller in response to an obstructing force on the object supported by the slip roller.
3 more elements
A roller conveyor comprising:
- a frame;
- a plurality of driven rollers arranged for conveyance of an object supported by the frame;
- a conveyor drive configured to rotate the plurality of driven rollers;
- a plurality of slip rollers circumscribing the plurality of driven rollers, each slip roller configured to slip in rotation relative to one of the plurality of driven rollers circumscribed by the slip roller in response to an obstructing force on a barrel supported by the slip roller;
- and
- wherein each slip roller comprises:
- an interior sleeve defining an interior surface of the slip roller and comprised of a thermoplastic material,
- an exterior sleeve defining an exterior surface of the slip roller and comprised of a durable metal, and wherein the interior sleeve having a diameter that is greater than an outer diameter of each of the driven rollers defining a spacing therebetween;
- one or more end pieces, each end piece having at least one opening sized and configured to receive ends of the plurality of driven rollers but having a diameter too small to receive the slip roller.
