AI Technical Summary

Benefits of technology

The polymeric rollers achieve significant weight reduction, enhance durability, and simplify maintenance by allowing visual inspection without disassembly, while maintaining performance under demanding conditions like rapid temperature and pressure changes, and reducing fuel consumption by lowering the overall weight of conveyor systems.

Problems solved by technology

However, unlike conventional rollers, the novel rollers contain lightening elements on the surface and / or within the roller.

Embodiment Construction

[0030]It has been discovered that the rollers of the present invention can be made lighter through the use of internal and / or external lightening elements, such as cavities and / or cutouts, while having the compressibility, impact strength and flexural strength described in the instant application. These lightweight rollers can handle heavy loads, corrosive environments and abusive treatment such as those found in the air transportation field.

[0031]The internal portion (or housing) of the roller is that portion between the outer surface of the roller and the inner surface of the roller which forms the aperture. An internal lightening element resides within these two surfaces. FIG. 1a depicts one example of a roller 110 of the invention. It shows a roller 110 with an outer surface 112, an inner surface 114, shoulders 116, and an aperture 118, with internal lightening elements 150 in the shape of cylinders (tubular). FIG. 1b shows an end view of the roller 110. One method of creating t...

Abstract

A roller made lighter through the use of lightening elements. The inventive roller, with its lightening element(s), is lighter yet maintains its overall dimensions, is strong and durable enough to withstand the rigors of the transportation industry and / or is cost effective to produce and maintain. The lightweight roller may be part of a system having at least one operable roller unit, each roller unit having a roller, cylindrical in shape having a length and a diameter, and a center aperture extending through the length of the roller, an axel / shaft having a diameter sized to rotatably fit within the central aperture of the roller, the shaft further having a retention mechanism located upon the shaft ends and an elongate “U” shaped roller rack, the roller rack sized to extend the length of the roller and having a pair of upwardly extending arms located adjacent the ends of the roller, each arm end having an aperture sized to receive the respective shaft end and locate the shaft with the roller in a fixed location. The roller system has at least one roller, preferably more or all of the rollers, having internal and / or external lightening elements.

Description

[0001]The present invention relates to lightweight rollers for conveyors. In one aspect, the rollers have a high strength to weight ratio. In another aspect, these rollers can be easy to manufacture, easy to use, economical to produce, and / or highly cost effective.[0002]Conveyors are used in various systems, including manufacturing plants, loading and unloading areas such as shipping and receiving docks, and cargo haulers, such as aircrafts, boats, trains and trucks. While some conveyors may have an extending belt which provides the carrying surface, many do not. Conveyors for large or packaged goods often do not have large belts and merely rely on a series of rollers to carry the product along a production line.[0003]One of the biggest factors in transporting goods by cargo haulers is the cost of fuel. Recently, the price for a barrel of oil has fetched well over $100 a barrel. These fuel costs can cut deeply into profits. It would, therefore, be desirable to reduce fuel consumptio...
