Solution Overview

Problem

Existing labeling machines face downtime issues when changing self-adhesive label rolls, as they lack efficient storage solutions for empty carrier tapes, leading to increased operational interruptions.

Innovation Solution

A labeling machine with a continuously drivable pull-off device for empty carrier tapes, which winds and stores the tapes on a mandrel, monitored by a sensor for optimal fill levels, allowing for seamless switching and continuous operation without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If a winding mandrel is used to store empty carrier tapes, then storage volume efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvestorage volume efficiencyVSAvoiddevice complexity
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The patent combines the winding mandrel with a pull-off device and sensor system into an integrated storage unit. The mandrel is positioned within easy reach of the labeling position, and the pull-off device is coupled to automatically retrieve tapes from the mandrel when needed, merging storage, retrieval, and monitoring functions into a cohesive system that achieves compact storage without proportionally increasing complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sensor device automatically detects when the winding mandrel is full and signals when carrier tapes need to be changed, eliminating the need for constant manual monitoring. The system serves itself by providing automatic detection and notification, reducing the operational burden while maintaining efficient storage

Inventive Principle:
Principle #25Self-service

2Ease of operation

If the pull-off device is positioned within the safety area, then ease of operation is improved, but operational safety deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidoperational safety
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a sensor device as an intermediary between the pull-off device and the control system. The sensor detects the position and status of the carrier tape and the winding mandrel, transmitting this information to the control device, which then automatically controls the pull-off device. This intermediary system allows the pull-off device to be positioned in the safety area for ease of operation while maintaining safety through automated control based on sensor feedback

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If manual tape changing is required, then device complexity is reduced, but productivity decreases

Engineering Contradiction:
Improvedevice complexityVSAvoidproductivity
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system performs self-service through the sensor device that automatically detects when the winding mandrel is full and when carrier tapes need to be changed. The control device receives this information and automatically controls the pull-off device to retrieve new tapes and switch them into position, eliminating the need for manual intervention and maintaining high productivity with minimal added complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The sensor device provides continuous feedback to the control device about the status of the carrier tape supply and the winding mandrel fill level. This feedback loop enables the control device to automatically initiate tape changes when needed, ensuring continuous operation and high productivity without requiring complex manual monitoring or intervention

Inventive Principle:
Principle #23Feedback
