Solution Overview

Problem

Existing methods for dividing and separating laundry batches, such as laundry cakes, inadequately separate articles and expose them to high mechanical loads during the separation process.

Innovation Solution

A method and apparatus where a conveyor transports a laundry batch to a dividing device that rotates about a horizontal axis, allowing the laundry articles to be drawn out from the end face of the batch, reducing mechanical stress and enabling effective separation without damaging the articles. The dividing device, often roller-like, draws articles upward and transversely, ensuring careful and complete separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the laundry cake is pressed together laterally to loosen it, then the laundry batch can be divided, but the laundry articles are exposed to high mechanical loads and the division is inadequate

Engineering Contradiction:

Improvedivision effectivenessVSAvoidmechanical loads on laundry articles

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

Instead of pressing the laundry cake laterally from the sides, the invention inverts the approach by inserting a divider vertically into the end face of the laundry cake. This vertical insertion method divides the laundry batch effectively while avoiding high lateral mechanical loads on the laundry articles, thus resolving the contradiction between division effectiveness and mechanical stress.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If lateral pressing is used to divide the laundry cake, then some separation occurs, but the separation is inadequate and articles are damaged

Engineering Contradiction:

Improveseparation qualityVSAvoidintegrity of laundry articles

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The invention inverts the conventional lateral pressing method by using vertical insertion of a divider into the end face of the laundry cake. This approach achieves complete separation of laundry articles while maintaining their integrity, as the vertical division method gently extracts articles rather than crushing them through lateral pressure.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The divider is designed to segment the laundry cake into individual articles or smaller batches through vertical insertion. This segmentation approach allows complete separation of laundry articles from the batch while minimizing mechanical damage, as each article is individually extracted rather than subjected to distributed lateral pressure.

Inventive Principle:

Principle #1Segmentation

AI summary

A method and apparatus in which laundry cakes (10), formed when washed laundry articles are for the most part freed in a dewatering press of the treatment liquid bound in them giving rise to a laundry cake (10) consisting of coherent laundry articles, are divided from the end face (15) by a roller-like divider (20) which can be driven in rotation about a horizontal axis of rotation (31), which axis of rotation (21) runs parallel to the end face (15) of the laundry cake (10) to be divided, and an effective division of the laundry cake (10) which takes care of the laundry articles is carried out.
