Embodiment Construction

[0020] Figure 1 to Figure 4 A portion of a modular plastic radius conveyor belt 10 is shown. This portion of the belt is located on a bend in the main direction of turn, with its inner side 12 almost completely constricted. There are special inner edge link ends or joints 14 on the inner edge, each said link end or joint has an opening for a link 16, each said opening is connected to a large number of the first set of link ends on each module 20. The openings on the intermediate link ends or joints 18 are aligned. Link ends 18 (referred to herein as intermediate link ends) are narrow and relatively closely spaced together as shown. Immediately inside the middle link end is a wider, heavier link end 22 and at the innermost edge is said special wide edge link end 14 . Outboard of the middle link end 18 are thicker, wider and heavier link ends 24 and a special outer edge link end 26 which is similar in most respects to the special inner edge link end 14 . All of these link e...

Abstract

The invention discloses a modular plastic conveyor belt is designed to turn a tight radius in one direction only. Particularly it is designed for use as a spiral conveyor belt, the belt can turn in the opposite direction, but with a much larger radius. At the outer edge of the belt, the link ends or knuckles are larger and heavier for increased strength in accepting tension at the outer edge of the belt. The outside knuckles or link ends are not only wider than at the inside, but they also are longer, with increased material beyond the rod opening for increased tension strength. By having wider link members at the inner edge, the belt can collapse more closely at the inner edge than would be possible if the turn were in the other direction, providing a tighter radius of turn. This is useful in spiral conveyors which ordinarily turn in only one direction through the entire path of travel.

Description

technical field [0001] The present invention relates to modular plastic conveyor belts and integrally molded modules which are held together, usually by links or pins, to form such modular belts. More specifically, the present invention relates to a modular belt (also known as a radius belt) that travels around a curve, and is well suited for use in helical (helical) conveyor belt systems. Background technique [0002] Conveyor belts of the general type referred to in the present invention are described in US Pat. For radius belts with relatively small turning radii, design points for modular belts focus on tight fit at the belt inner edges, sharp turn ratios, sufficient beam strength to support items conveyed on the belt, sufficient Tensile strength (whether in turns or in a straight line), airflow over the belt, and reduced vibration at the inner edge of the edge-driven helical belt, among others. None of the existing belts disclose an effective design of the present inv...
