Label Printer Automatic Lamination for Confidential Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label printers are inadequate for securely printing and sticking confidential information on a smaller label between a larger label and an object, as they require manual folding and expose adhesive areas incompletely, leading to unintended peeling and floating issues.
Innovation Solution
A label printer with a feed-out mechanism for raw strip sheets, printing, peeling, and laminating means that automatically aligns and laminates smaller labels between larger ones, ensuring the adhesive layer of the smaller label is exposed around the periphery to secure it fully, using suction plates for precise positioning and tear-off lines for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a label is folded back by hand to conceal confidential information, then confidentiality is achieved, but the operation becomes manual and time-consuming
Solution Approach 1:
The label structure enables itself to be folded automatically through the adhesive interaction between the first and second labels. The second label's adhesive layer bonds to the first label's adhesive layer, creating a self-folding mechanism that eliminates manual intervention while maintaining confidentiality.
Solution Approach 2:
The labels are pre-configured with adhesive layers positioned to enable automatic folding. The first label is prepared with an adhesive layer that will bond to the second label's adhesive layer, so that when the second label is applied, the folding action occurs automatically without requiring manual intervention.
2Loss of information
If a label is folded back to conceal information, then confidentiality is improved, but adhesive exposure is incomplete leading to peeling and floating
Solution Approach 1:
The adhesive layers are strategically positioned with specific local properties. The first label has an adhesive layer that extends beyond the second label's boundaries, creating a local adhesive border that ensures complete bonding to the object surface. This local adhesive quality prevents peeling and floating while maintaining the folded configuration for confidentiality.
Solution Approach 2:
The adhesive layer of the first label is designed to extend beyond the second label's perimeter in advance, creating a cushioning adhesive border that prevents potential peeling and floating issues before they occur. This pre-positioned adhesive overflow ensures complete bonding coverage.
3Adaptability or versatility
If a sheet type delivery slip is used, then printing flexibility is improved, but confidential information becomes visible from the outside
Solution Approach 1:
The second label containing confidential information is nested within the first label. When the second label is folded back and bonded to the first label, it creates a nested configuration where the confidential information is hidden inside the folded structure, while the first label remains visible on the object surface for printing flexibility.
Solution Approach 2:
The delivery slip is segmented into two functional labels: the first label for external attachment and non-confidential information, and the second label for confidential information that is folded back and concealed. This segmentation allows the sheet type structure to maintain printing flexibility while protecting confidential information through the folded configuration.
4Device complexity
If adhesive layer is exposed partially after folding, then label structure is simplified, but peripheral portions float and wave causing unintended peeling
Solution Approach 1:
The adhesive layer of the first label is designed with extended local coverage that goes beyond the second label's boundaries. This creates a local adhesive border around the perimeter that ensures complete bonding to the object surface, preventing floating and waving of peripheral portions while maintaining a relatively simple overall label structure.
Solution Approach 2:
The adhesive layer is pre-positioned to extend beyond the second label's perimeter, creating a cushioning effect that prevents potential floating and peeling issues before they occur. This adhesive overflow is built into the label structure design, ensuring reliable bonding without complex additional components.

Function Achieved in This Case
The solution ensures complete concealment of confidential information, prevents peripheral floating, and facilitates easy tearing and rolling of the labels, ensuring accurate and secure lamination and concealment of printed information.

AI summary
There is provided a printing device 12 that performs printing on each of first and second labels L1, L2 on the way of feeding out a raw strip sheet M, which is temporarily stuck with a first label L1 and a second label L2 having a smaller plane area than that of the first label on a release liner S, a peel plate 27 that peels off the first and second labels L1, L2 from the release liner S, first and second label suction plates 30, 31 that hold the respective peeled labels L1, L2, and a laminating device 17 that laminates the first and second labels L1, L2 with the adhesive layer of the second label L2 facing the adhesive layer of the first label L1. The adhesive layer of the first label L1 laminated with the second label L2 is exposed in a closed loop manner in an outer peripheral area all around the second label L2.
