Removable Multi-Belt Cartridges for Precise Item Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-belt conveyors face challenges in maintaining consistent gaps between items of varying sizes and shapes, leading to reduced throughput, jamming, and misalignment of conveyor belts during maintenance, which disrupts the conveying surface.
Innovation Solution
A multi-belt conveyor system with removable cartridges, each comprising a roller-slider bed, drive pulley, and conveyor belts, allowing for varying speeds and accelerations to create programmed gaps and align items, while enabling modular mounting and dismounting without disturbing adjacent cartridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conveyor belts are made continuous and non-removable to maintain consistent gaps between items, then gap consistency is improved, but maintenance complexity and downtime increase
Solution Approach 1:
The conveyor system is divided into modular cartridge assemblies that can be independently removed and replaced. Each cartridge contains a complete set of conveyor belts, rollers, and drive mechanisms, allowing maintenance personnel to service individual modules without disrupting the entire conveyor system. This segmentation maintains gap consistency during operation while dramatically simplifying maintenance procedures.
2Loss of time
If conveyor belts are made removable for easy maintenance, then maintenance downtime is reduced, but alignment consistency and gap control deteriorate
Solution Approach 1:
The cartridge assemblies are pre-assembled with precisely aligned conveyor belts, rollers, and drive mechanisms in a controlled manufacturing environment. This preliminary alignment ensures that when cartridges are installed on the conveyor system, they maintain consistent gaps and proper alignment without requiring field adjustment. The pre-alignment capability enables quick cartridge replacement while preserving alignment consistency.
3Productivity
If multiple conveyor belts operate at different speeds to create gaps between items, then item spacing is improved, but system complexity increases
Solution Approach 1:
Different sections of the conveyor system, implemented as separate cartridges, are equipped with independent speed control capabilities. Each cartridge can operate at different speeds to create programmed gaps between items at specific locations along the conveyor. This local quality approach allows variable speed operation only where needed, rather than controlling the entire conveyor system uniformly, thus improving item spacing control while managing system complexity.

AI summary
A multi-belt conveyor is described. The multi-belt conveyor comprises a base assembly comprising a base frame that extends along a length of the multi-belt conveyor. Further, the multi-belt conveyor comprises a conveyor bed having a plurality of cartridges positioned adjacently to each other and mounted to the base frame. In this regard, each cartridge of the plurality of cartridges comprises a set of conveyor belts configured to move in a direction along the conveyor bed at a defined speed. Further, in accordance with some example embodiments, a cartridge of the plurality of cartridges is configured to be removed from the conveyor bed without removing an adjacent cartridge from the plurality of cartridges. Further, each cartridge of the multi-belt conveyor comprises an actuation assembly comprising: a drive pulley, a roller-slider bed comprising a plurality of rollers, and the set of conveyor belts mounted around the roller-slider bed and the drive pulley.
