Solution Overview

Problem

Automated label application devices face challenges in loading linerless media rolls due to their stickiness and complex design, which complicates the integration of cutting and application mechanisms, leading to operational issues.

Innovation Solution

The integration of a cutting mechanism with the applicator system, where the tamp arm combines the cutting motion with the application motion, simplifying the design and reducing the number of components, making it easier to load, assemble, clean, and maintain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a separate cutting mechanism is integrated into the label application device, then the cutting function is improved, but the device complexity increases

Engineering Contradiction:

Improvecutting functionVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the cutting mechanism with the applicator system by mounting the cutting blade on the tamp arm, which performs both application and cutting functions. This integration eliminates the need for a separate cutting mechanism while maintaining the cutting function, directly resolving the technical contradiction between versatility and device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The tamp arm is designed to perform multiple functions: it applies the label to the substrate and simultaneously cuts the media roll. This multi-functionality approach allows the system to achieve cutting capability without adding separate components, thereby improving versatility while controlling device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate mechanisms (cutting and application) are used, then the cutting and application functions are reliable, but the ease of operation deteriorates

Engineering Contradiction:

Improvecutting and application reliabilityVSAvoidease of loading

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

By integrating the cutting blade onto the tamp arm, the system reduces the number of separate mechanisms that need to be loaded and assembled. Users only need to load the media roll once, and the integrated system automatically handles both application and cutting, significantly improving ease of operation while maintaining reliability through the coordinated design of the combined mechanism.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If multiple separate mechanisms are integrated, then the cutting and application functions are achieved, but the ease of manufacture deteriorates

Engineering Contradiction:

Improvecutting and application capabilityVSAvoidease of assembly

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The cutting blade is mounted directly on the tamp arm as an integrated component, reducing the number of separate assemblies that need to be manufactured and assembled. This integration simplifies the manufacturing process and assembly procedures while achieving both cutting and application capabilities, directly addressing the ease of manufacture concern.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If multiple separate mechanisms are used, then the cutting and application functions are reliable, but the ease of repair deteriorates

Engineering Contradiction:

Improveoperational reliabilityVSAvoidease of cleaning and maintenance

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The integrated design with the cutting blade mounted on the tamp arm reduces the number of separate mechanisms that need to be disassembled for cleaning and maintenance. The simplified structure with fewer components makes the system easier to access, clean, and maintain while maintaining operational reliability through the robust integrated design.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Disclosed is a label application device for applying a label to an object. The label application device comprises a media roll holder configured to secure a media roll, a tamp arm configured to move from a retracted position to an extended position, and a print head located between the media roll holder and the tamp arm. The print head is configured to receive the media roll, feed the media roll into the print head, and eject the media roll. The tamp arm comprises a tamp pad attached to an end of the tamp arm. The tamp pad comprises a vacuum port configured to suction the media roll against the tamp pad. The tamp arm further comprises a blade attached to the tamp arm. The blade is configured to cut the media roll as the tamp arm moves from the retracted position to the extended position.
