Label Peeling Device Using Pressing Unit Curvature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label peeling devices face difficulties in peeling single cut label sheets where the label body is adhered to a liner sheet, often requiring additional components that increase device size and cost.
Innovation Solution
A label peeling device with a tray, pressing unit, and control unit that uses a lateral alignment plate to drive the pressing unit perpendicular to the label sheet, peeling the liner sheet from the label body by curving the sheet and utilizing the restoring force to facilitate easy separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a component exclusively used to peel the label body is provided, then the label peeling function is improved, but the device size and production cost increase
Solution Approach 1:
The pressing unit, originally designed for alignment purposes, is made to perform dual functions by adding a pressing capability. This allows the same component to both align the label sheet and press the label body for peeling, eliminating the need for a separate dedicated peeling component and thereby reducing device size and complexity
2Ease of operation
If a component exclusively used to peel the label body is provided, then the label peeling function is improved, but the production cost increases
Solution Approach 1:
By designing the pressing unit to serve multiple purposes (alignment and pressing for peeling), the number of components that need to be manufactured and assembled is reduced. This multi-functionality approach lowers production costs by eliminating the need to produce and integrate a separate dedicated peeling component
3Ease of operation
If the label sheet is curved by pressing the edge, then the label body is peeled from the liner sheet, but additional pressing mechanism is required
Solution Approach 1:
The pressing unit is designed to perform both alignment and pressing functions. When the edge of the label sheet is pressed, the sheet curves and the label body peels from the liner sheet. This dual-function design eliminates the need for additional pressing mechanisms while achieving the desired peeling effect

AI summary
According to one embodiment, a label peeling device includes a tray, a pressing unit, and a control unit. The tray is configured to support a label sheet thereon. The pressing unit is configured to be driven in a direction perpendicular to a conveyance direction of the label sheet. The control unit is configured to drive the pressing unit toward a central portion of the label sheet supported on the tray. The control unit performs peeling control to peel a liner sheet and a label body of the label sheet from each other by pressing an edge of the label sheet and thereby curving the label sheet.
