Automated Tagging Device for Moving Lineal Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying lineal objects like wire, banding, or twine during continuous manufacturing processes require the objects to be stationary, which is inefficient and labor-intensive, especially when packaging materials like bales of hay or cotton modules.
Innovation Solution
A device that applies an adhesive tag around a moving lineal object by dispensing tags from a roll, routing them around a sharp bend to release from the backing, and using lifting members and compression rollers to secure the tag around the object as it moves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tags are applied to stationary lineal objects after manufacturing, then identification accuracy is achieved, but productivity is reduced and labor intensity increases
Solution Approach 1:
The patent transforms the tagging system from a static, manual process to a dynamic, automated one. The tagging device moves with the continuous flow of lineal objects on the manufacturing line, with lifting members that dynamically raise and lower the tagging head to engage with passing objects. The tag feed mechanism dynamically advances tags in synchronization with the moving objects, enabling automated tagging without stopping production.
Solution Approach 2:
The system enables self-service tagging where the moving lineal objects themselves participate in the tagging process. As objects pass through the tagging device, their motion triggers the automated sequence: lifting members raise the tagging head, tags are fed and applied, and compression members secure the tags. The continuous flow of objects drives the entire tagging operation without external intervention.
2Ease of manufacture
If the tagging device routes tags around a sharp bend, then tag release from backing is achieved, but tag positioning precision must be maintained
Solution Approach 1:
The sharp bend acts as an intermediary mechanism that facilitates tag release from the backing. As the tag roll navigates the bend, friction and mechanical stress cause tags to separate from the backing material in a controlled manner. This intermediary action enables automatic tag release without complex active release mechanisms, while guide members maintain precise positioning throughout the process.
Solution Approach 2:
The use of a sharp bend (curved path) for routing tags provides a passive yet effective release mechanism. The curvature creates natural separation forces as tags navigate the bend, allowing them to peel away from the backing. This curved path design simplifies the release mechanism while maintaining control over tag positioning through properly designed guide surfaces.
3Extent of automation
If lifting members raise the lineal object for tagging, then automated tagging is enabled, but device complexity increases
Solution Approach 1:
The lifting members operate in a periodic cycle synchronized with the passage of lineal objects. They raise the tagging head or object at regular intervals when needed, then return to their initial position. This periodic action enables automated tagging functionality while keeping the lifting mechanism simple and predictable, driven by timing mechanisms that coordinate with the continuous flow of objects.
Solution Approach 2:
The lifting function is segmented into discrete, independent components rather than a continuous complex mechanism. Individual lifting members or actuators handle specific tasks at specific points in the cycle, allowing for simpler, more maintainable design. Each lifting element can be independently controlled and replaced if needed.

Function Achieved in This Case
Enables efficient and automated identification of lineal objects during continuous manufacturing, improving productivity by allowing tagging during the manufacturing process without the need for manual application on stationary objects.
Implementation Method 1
The adhesive tag is dispensed from a roll of continuous tags that are temporarily adhered to a roll of backing
Implementation Method 2
As the object returns to its original position, it pulls the tag through a squeeze point, thus closing the label around the lineal object
