Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing devices for laminated label bodies are complex, expensive, and require significant space due to the use of release papers and endless belt members, leading to inefficiencies in label lamination and increased costs.
Innovation Solution
A manufacturing device that laminates labels without release paper, utilizing a peeling device with a peeling plate and a lamination device with a lamination pull roll and guide roll, allowing for adjustable conveying speeds and positions to achieve precise label overlap and adhesion, thereby simplifying the configuration and reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If release paper and endless belt member are used in the manufacturing device, then label lamination can be achieved, but device complexity increases and installation space becomes larger
Solution Approach 1:
The invention extracts and removes the release paper from the manufacturing system. Instead of using release paper to hold labels during processing, the system directly laminates labels onto the product surface, eliminating the release paper component and simplifying the overall device configuration while maintaining label lamination capability
Solution Approach 2:
The invention merges the label transfer function directly into the lamination process. The label is transferred from the label sheet directly to the product surface through the lamination device, combining what were previously separate operations (release from release paper, then lamination) into a single integrated process that reduces device complexity
2Productivity
If release paper and another peeling portion are used, then continuous label bodies can be manufactured, but installation space increases
Solution Approach 1:
The invention removes the release paper and separate peeling portion from the system. Labels are peeled directly from the label sheet at the lamination location and transferred to the product, eliminating the need for separate peeling equipment and reducing installation space while maintaining continuous production capability
Solution Approach 2:
The invention changes the spatial arrangement by performing label peeling and transfer in the same localized area rather than using separate sequential stations. The lamination device handles both the peeling of labels from the sheet and their application to the product in a compact integrated configuration, reducing the footprint required for continuous label body production
3Manufacturing precision
If lamination pull roll and guide roll are used with rotational pressure, then precise label overlap and adhesion can be achieved, but device complexity increases
Solution Approach 1:
The lamination pull roll and guide roll serve multiple functions simultaneously: they convey the label material, apply rotational pressure for precise overlap positioning, and provide the adhesion force for label bonding. This multi-functionality achieves manufacturing precision without requiring additional separate devices, thereby avoiding increased device complexity
Solution Approach 2:
The invention uses adjustable rotational speed and pressure parameters of the lamination pull roll and guide roll to achieve precise label overlap. By controlling the rotational speed ratio and pressing force, the system can precisely position label edges for overlapping while maintaining a simple two-roll configuration, achieving manufacturing precision without complicating the device structure
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
The device enables the efficient production of laminated label bodies with overlapping labels in a continuous strip, reducing resource usage, improving work efficiency, and minimizing environmental impact while allowing for flexible label application without the need for release paper.
Implementation Method 1
a tip end portion of the label peeled off in the peeling device is fed into an area for applying rotational pressure between the lamination pull roll and the guide roll while being in contact with the circumferential surface of the guide roll, and the second conveying speed is slower than the first conveying speed, so that a rear end portion of the preceding label and a tip end of the subsequent label are adhered to each other in an overlapped state to be laminated

AI summary
A manufacturing device of a laminated label body can manufacture a laminated label body without using a release paper, with simple and space-saving configuration. The manufacturing device of a laminated label body includes a paper feeding portion 2, a peeling device 3, a winding portion 4, and a lamination device 5. The release paper 12 to which a label 13 is stuck is conveyed by the paper feeding portion 2, and the release paper 12 is wound by the winding portion 4 and is conveyed while being folded back around a tip end portion 30a of a peeling plate 30 of the peeling device 3, whereby the label 13 is peeled off from the release paper 12. The peeled-off label 13 is conveyed to the lamination device 5 having two rolls provided on a downstream side of the peeling plate 30. The lamination device 5 manufactures the laminated label body by overlapping a rear end portion of the preceding label 13 and a tip end portion of the subsequent label 13 and by sticking them each other.
