Solution Overview

Problem

Existing conveyor systems for hanging products face challenges in providing flexible and efficient spacing between product carriers to prevent collisions and entanglement, especially when dealing with varying product sizes and shapes, and require complex solutions for integrating stop elements and modular guide rails.

Innovation Solution

A modular guide rail part with an integrated actuator and stop member that automatically adjusts its position based on the presence of product carriers, allowing for customizable spacing and easy integration with existing conveyor systems, using pivotable mechanisms and resilient members to control the stop function and accommodate different product carrier configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a separate guide rail is used instead of integrating it in the main rail, then flexibility for inserting switch units is improved, but the guide rail still needs to be cut off which complicates rebuilding

Engineering Contradiction:
Improveflexibility for inserting switch unitsVSAvoiddifficulty to rebuild
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The guide rail is divided into modular guide rail elements that can be independently removed and repositioned. Each element can be detached from the main rail without cutting, allowing switch units to be inserted by simply removing and repositioning individual elements rather than cutting the entire rail structure.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If multiple active stop elements are provided to allow product carriers to queue with predefined distance, then spacing control is improved, but the system complexity and cost increase

Engineering Contradiction:
Improvespacing control between product carriersVSAvoidnumber of active stop elements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The guide rail element incorporates an automatic stop function that activates when a product carrier is present on the rail. The stop member automatically engages to prevent subsequent carriers from approaching too closely, and automatically disengages when the carrier passes, eliminating the need for externally controlled active stop elements.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If product carriers are provided with integrated spacers or protective covers, then collision prevention is improved, but the product carrier design becomes more complex and less adaptable to different products

Engineering Contradiction:
Improvecollision and entanglement preventionVSAvoidadaptability to different product sizes and shapes
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

Instead of adding longitudinal spacers to product carriers, the solution introduces a lateral stop member that acts perpendicular to the direction of travel. The stop member engages the side of the product carrier to maintain spacing, allowing carriers to remain simple while collision prevention is achieved through a different spatial dimension.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Guide rail part for a conveyor adapted to convey product carriers in a hanging manner, where the guide rail part is adapted to be positioned centrally in a main rail of the conveyor, where the guide rail part comprises a body,wherein the guide rail part comprises an actuator pivotably suspended to the body, where the actuator is movable from a first upper position to a second lower position, and a stop member pivotably connected to the actuator such that the stop member is in a raised stop position when the actuator is in the second lower position and that the stop member is in a lowered bypass position when the actuator is in the first upper position. The advantage of the guide rail part is that a queue with product carriers can be realised, where the spacing between the product carriers is obtained with the guide rail parts in an easy and cost-effective way.
