Solution Overview

Problem

The existing methods for determining the thickness of transport bags in overhead conveyor systems are time-consuming and complex, hindering efficient and trouble-free conveying in hanging conveyor systems.

Innovation Solution

Instead of determining the thickness of transport bags, the system records the number of hanging adapters on a conveyor rail to variably set the transport distance, using detection sensors and a control unit to ensure efficient conveying by calculating the average distance between adapters, allowing for contactless and reliable detection and separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the thickness of transport bags is determined to set transport distance, then the conveying can be adapted to different bag types, but the process becomes time-consuming and complex

Engineering Contradiction:
Improveadaptability to different bag typesVSAvoidtime-consuming thickness determination
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The invention extracts the measurement task from thickness determination to adapter counting. Instead of measuring the physical dimension of each transport bag, the system counts the number of hanging adapters within a detection range. This extraction simplifies the measurement process while maintaining adaptability, as the number of adapters directly indicates the total thickness without requiring complex measurements.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the mechanical thickness measurement system with an optical detection system that counts hanging adapters. The detection unit uses optical sensors to detect the presence and number of adapters rather than physically measuring bag thickness, thereby reducing complexity and measurement time while maintaining accuracy.
