Solution Overview

Problem

Existing devices for processing label strips, particularly for unwinding from rolls, face challenges such as label rolls falling apart when lifted onto the dispensing unit, requiring cumbersome handling and limited space for roll placement.

Innovation Solution

A device with a support surface and a detachable guide device that allows label rolls to be easily positioned and secured relative to their axis of rotation, enabling rotation without displacement, and a movable processing unit to accommodate roll changes and provide space for label roll insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If label rolls are lifted onto the dispensing unit from above, then the label rolls can be positioned on the dispensing unit, but the label rolls may fall apart during lifting

Engineering Contradiction:
Improvelabel roll positioningVSAvoidlabel roll integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The guide device is pre-positioned on the support surface before the label roll is placed. The guide device includes a guide shaft that extends through the support surface, creating a predetermined path and support structure before the roll is introduced, preventing collapse during the placement operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The guide device acts as an intermediary element between the label roll and the support surface. The guide shaft serves as a structural mediator that provides internal support to the label roll, preventing it from falling apart during lifting and positioning operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a fixed mandrel is used to guide label rolls, then the label rolls can be guided through an opening, but the device structure becomes complex and space-constrained

Engineering Contradiction:
Improvelabel roll guidanceVSAvoidmandrel structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The guide device is segmented into separate functional components: a guide shaft that extends through the support surface and a peripheral body that rotates with the label roll. This segmentation allows each component to perform its specific function independently, simplifying the overall structure compared to a monolithic fixed mandrel.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide device transitions from a static fixed mandrel to a dynamic system where the peripheral body rotates with the label roll. This dynamic configuration allows the guide device to adapt to the rotational motion of the roll while maintaining structural support, reducing the need for complex fixed positioning mechanisms.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If label rolls are pushed onto the support surface in the plane of the support surface, then space is freed for roll insertion, but the processing unit must be movable to accommodate this

Engineering Contradiction:
Improvespace for roll insertionVSAvoidprocessing unit mobility
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The processing unit is designed with movable components that can reposition themselves to accommodate the insertion and removal of label rolls. This dynamic capability allows the processing unit to clear space when needed while maintaining its functional position during operation, balancing space requirements with operational needs.

Inventive Principle:
Principle #15Dynamics

AI summary

The device (1) has an unwinder (2a) to wind around the label strips of a label strip role arranged opposite to each other in relation to a part of the unwinder in a rotating manner. The unwinder has a bearing surface (4a,4b), where the label strip role is taken, and has a guidance device (10) provided at the bearing, which is conductible by an opening arranged in the label strip role. The guidance device is detachable from the bearing surface.
