Solution Overview

Problem

Existing feed transport systems for hangers require laborious manual handling as hangers need to be individually hung in rolling holding elements for transportation, which is inefficient.

Innovation Solution

A feed transport system where the transfer wheel is angled to catch the hook of a hanger as it falls through a transfer gap, allowing the hanger to be automatically caught and then transported by a rotating transfer wheel, enabling cyclic loading and unloading of holding elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual handling is used to hang hangers in rolling holding elements, then the process is simple and reliable, but labor efficiency is low and productivity is poor

Engineering Contradiction:
Improvehanger loading efficiencyVSAvoidtransfer mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The hanger automatically engages with the transfer wheel mechanism through its own weight and geometry. The hook-shaped hanger falls through the transfer gap and is passively caught by the angled recess of the transfer wheel without requiring manual intervention or complex actuation systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The transfer wheel features an angled recess with a curved surface that matches the hook geometry of the hanger. This curved engagement surface guides the hanger hook into proper alignment and secures it during the transfer process, enabling reliable automatic loading.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Extent of automation

If the transfer wheel is positioned vertically, then the structure is simple, but hangers cannot be automatically caught and transferred

Engineering Contradiction:
Improvehanger transfer automationVSAvoidtransfer wheel configuration
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The transfer wheel is tilted at a specific angle relative to the vertical axis, creating an asymmetric configuration. This angular offset allows the hanger to fall through the transfer gap and be caught by the angled recess, enabling automatic transfer while maintaining structural simplicity.

Inventive Principle:
Principle #4Asymmetry

3Productivity

If multiple hangers are processed simultaneously, then productivity increases, but control precision and reliability decrease

Engineering Contradiction:
Improvehanger processing rateVSAvoidhanger positioning accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The transfer wheel rotates in discrete cyclic steps, with each rotation bringing one recess into position to catch a single hanger. This periodic motion ensures that only one hanger is transferred at a time, maintaining positioning accuracy while achieving continuous high-rate processing through repeated cycles.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The transfer wheel is divided into multiple identical recesses arranged around its circumference. Each recess independently handles one hanger, allowing the system to process multiple hangers sequentially through continuous rotation while maintaining precise control over each individual transfer event.

Inventive Principle:
Principle #1Segmentation

AI summary

The system (1) has a handover wheel attached to a handover station (13) and movable around a rotation axis. A handover slot is arranged at an end of a transport rail (2) that is attached to the station. The wheel and the slot are arranged in such a manner that a retaining unit (14) with its retaining opening (18) is provided below the free ends of a hook (10) of a hanger (11), where the retaining unit transversely projects from the wheel in a handover position. A recess is provided for accommodating the unit.
