Abstract

A roller unit suitable for application to the side walls of chain link conveyors, including along their curved portions, and containing modules, each of which includes a flat plate, from the opposing sides of which there extends a first pair of brackets between which there are supported the fixing pins of the constituent idle rollers of the roller unit, and a second pair of brackets for receiving the conveyor side wall and the elements for fixing the module thereto, the second pair of brackets being provided with recesses which extend to also involve the plate.

Claims

1. A roller unit suitable for application to the side walls of chain link conveyors, including along their curved portions, which comprises modules, each of which includes a flat plate, from the opposing sides of which there extends a first pair of brackets between which there are supported the fixing pins of the constituent idle rollers of the roller unit, and a second pair of brackets for receiving the conveyor side wall and the means for fixing the module thereto, said second pair of brackets being provided with recesses which extend to also involve the plate.

2. The roller unit as claimed in claim 1, wherein the means for fixing the module to the side wall consists of pegs inserted into opposing seats provided in said second pair of brackets.

3. The roller unit as claimed in claim 2, wherein said second bracket pair, which are defined by said recesses, houses at least one peg for fixing the roller unit to the side.

4. The roller unit as claimed in claim 1, wherein the plate comprises a line of narrow cross-section which enables it to be deformed, with consequent divergence of the brackets of said first bracket pair.

5. The roller unit as claimed in claim 1, wherein the plate comprises interruptions between the portions involved by the recesses.

6. The roller unit as claimed in claim 1, wherein said first bracket pair comprises equidistant opposing dead cavities for receiving the fixing pins for the idle rollers.
