Adhesive Marking for Automated Roll Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging systems face challenges in seamlessly replacing supply rolls of shrink film without manual intervention, leading to cumbersome and labor-intensive processes, especially in automated setups where the alignment of new rolls is uncertain.
Innovation Solution
A storage roll with a core and sheet or strip material featuring multiple windings, equipped with adhesive markings that provide optical recognition of the free end area's position, allowing for automated alignment and connection to the packaging system, and potentially incorporating RFID transponders for additional information storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual alignment and rotation of the new roll is performed to locate the free end area, then the welding connection can be established, but the process becomes cumbersome and labor-intensive
Solution Approach 1:
The adhesive marking is applied to the roll in advance during manufacturing, indicating the position of the free end area. This preliminary action eliminates the need for manual alignment and rotation during roll replacement, as the marking is already in its correct position to guide the automated system.
Solution Approach 2:
The manual mechanical alignment process is replaced by an automated optical detection system that reads the adhesive marking. The sensor automatically detects the marking position and guides the roll replacement, substituting human-operated mechanical alignment with automated sensor-based positioning.
2Extent of automation
If automated roll replacement is implemented without alignment markings, then labor is reduced, but the position of the free end area becomes unknown and alignment fails
Solution Approach 1:
The adhesive marking serves as an intermediary carrier of information about the free end area position. It mediates between the physical roll and the automated detection system, providing the necessary positional information that enables automated alignment without manual intervention.
Solution Approach 2:
The adhesive marking utilizes optical contrast (color or reflectivity difference) to provide visual information detectable by sensors. This optical property allows the automated system to distinguish the marking from the rest of the roll surface and determine the free end area position.
3Ease of manufacture
If the free end area is not properly secured, then roll replacement is simple, but the film material may unwind unintentionally causing defects
Solution Approach 1:
The adhesive marking is applied in advance to secure the free end area to the outer layer. This preliminary securing action prevents unintentional unwinding during handling and replacement, ensuring reliability while maintaining ease of manufacture through a simple application process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates the simplified and automated exchange of supply rolls, reducing the risk of film material unwinding and enabling uninterrupted packaging processes by providing clear visual and sensor-based alignment and identification of the free end area, thus streamlining the handling and integration of new rolls into the packaging machinery.
Implementation Method 1
The supply roll also has at least one adhesive marking, which is connected to an outer free end area of the flat and/or strip material and at least partially to an outer layer of the flat and/or strip material adjacent to the free end area by an adhesive bond.
