Double-Sided Label Printer With Segmented Adhesive Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-sided printing label printers require complex adjustments to the adhesive layer and release liner configuration, limiting flexibility in printing area selection and concealment of information on the rear face side of labels.
Innovation Solution
A double-sided printing label printer with separate first and second printing devices and a laminating section that allows for partial exposure of the adhesive layer of the first label, enabling unrestricted printing area and location on both labels, with the second label laminated to the first label's adhesive side, allowing for continuous printing and sticking without restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hole with no adhesive layer is formed in the release liner to enable printing on the adhesive layer side of the label, then printing on the rear face side of the label becomes possible, but the layout of the adhesive layer and the configuration of the hole must be changed every time the printing area changes, restricting freedom in selecting the printing area
Solution Approach 1:
The invention divides the label structure into two separate labels: a first label with an adhesive layer for printing on its front face side, and a second label without an adhesive layer for printing on its rear face side. The second label is temporarily stuck to the release liner during printing, then removed and laminated to the adhesive layer side of the first label. This segmentation eliminates the need to modify the adhesive layer or release liner configuration when changing printing areas, as each label can be independently configured and printed upon.
2Adaptability or versatility
If the second label is laminated to the first label's adhesive layer side with partial exposure of the adhesive layer, then unrestricted printing area and location on both labels is enabled, but the laminating process becomes more complex
Solution Approach 1:
The second label is temporarily stuck to the release liner in advance before the actual laminating process. This preliminary positioning allows the second label to be precisely aligned and held in place during printing operations. After printing, the second label is easily removed from the release liner and laminated to the first label's adhesive layer side, with the adhesive layer partially exposed. This preliminary action simplifies the overall process by pre-establishing the second label's position, enabling flexible printing area selection without complicating the final laminating step.

AI summary
A first printing device 12 that performs the printing on a first label L1, a second printing device 18 that performs the printing on a second label L2, and a laminating section 20 that laminates these labels one another and discharges the same therefrom and a sticking device 21 that sticks the first and second labels L1 and L2 to an object W. An unprinted surface of the second label L2 is attached to an adhesive layer A of the first label L1 and a printed surface of the second label L2 is positioned between the object W and the same to be hidden.
