Structure with idle rollers for guide walls of goods conveyors
First Claim
1. A structure with idle rollers for guide walls of goods conveyors comprising a surface for conveying the goods and at least one plate-like wall element extending longitudinally along the conveyor surface, following its path, the plate-like element having idle rollers rotatable about rotation axes arranged side by side and disposed at an angle to the surface for conveying the goods, and including roller-carriers each equipped with a predetermined number of rollers, the roller-carriers being articulated to one another and fixed to the plate-like wall element, each roller-carrier comprising a plate-like web with at least two parallel opposed sides spaced apart longitudinally in the direction of the axes of rotation of the idle rollers, a pair of plates each connected transversely to the web, on a respective one of its opposed sides, the plates having respective free edges projecting relative to the web, a plurality of seats formed in the pair of opposed plates for supporting the ends of axles of the idle rollers, engagement means for connection to the wall element of the conveyor, and engagement means for articulation to adjacent roller-carriers, wherein the engagement means for the connection of each roller-carrier to the wall element of the conveyor comprise a pair of tabs fixed to the opposed plates of the roller-carriers and projecting relative to the web of the roller-carrier on the opposite side to that having seats for supporting the ends of the axles of the rollers, each tab having a respective pair of stop teeth opposite those of the other tab, each tooth being positioned at a distance from the web substantially equal to the thickness of the wall element, at least one tab of the pair of tabs being resiliently flexible in the plane also containing the other tab, which is substantially rigid.

Abstract
A structure with idle rollers is intended for guide walls of goods conveyors comprising a surface for conveying the goods and at least one plate-like wall element extending longitudinally along the conveyor surface, adjacent to at least one of its edges, following its path. Roller-carriers each having a predetermined number of rollers mounted idly on axles and rotatable about rotation axes are snap-fitted on the plate-like wall element. The ends of the axles are supported by plates carried by the roller-carrier. The length of each roller-carrier depends on the minimum radius of curvature encountered in the path of the goods-conveying surface of the conveyor. The roller-carriers are connected to one another by snap-engagement members. The ends of the axles of the rollers are also snap-fitted in respective seats in the plates of the roller-carrier.
