Modular idle roller belt for conveyor of articles

摘要

A modular roller belt (100,200) for transporting articles is proposed. The belt comprises a plurality of modules (105) for transporting the articles, and a plurality of hinge pins (110), each for hinging adjacent modules of the belt about a corresponding geometric axis (GAX). Each module comprises at least one roller (115a,115b,115c,115d) and at least one mounting pin (1201,1202) for mounting the at least one idle roller to the respective module; the at least one roller is freely rotatable about a respective rotation axis (RAX1, RAX2) defined by the corresponding mounting pin. In the solution according to one or more embodiments of the present invention, the rotation axis of facing rollers of adjacent modules along a belt moving direction (x) and the geometrical axis of the hinge pin located there between are spaced apart, in a direction orthogonal to a moving direction (sN) of the respective module, a vertical distance (H) such that a minimum distance between the outer surface of these rollers and the outer surface of the corresponding hinge pin is less than or equal to 3 mm.

主权项

1. A modular roller belt for a conveyor of articles, said belt comprising:
a plurality of modules including a first module for conveying the articles, said first module including an upper surface and at least one roller rotatably mounted above said upper surface for rotation about a rotation axis and defining a support surface for supporting an article being conveyed, said rotation axis being spaced above said upper surface of said first module when said support surface supports an article being conveyed; and a plurality of hinge pins, each hinge pin of said plurality of hinge pins having a hinge pin outer circumference and hinging said first module to an adjacent module of the plurality of modules around a corresponding geometric axis, when said support surface supports an article being conveyed, said at least one roller of said first module having a roller outer circumference, in a vertical direction orthogonal to a flowing direction, a lower portion of said roller outer circumference extends downwardly toward said upper surface and overlaps an upper portion of said hinge pin outer circumference.
