Chevron-Shape Label Sheet Manufacturing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing label attachment process is cumbersome and complicated due to the need for manual folding of labels from a planar shape to a chevron shape before attachment to an article.
Innovation Solution
A label sheet and manufacturing device that temporarily attach a folded label portion to a backing sheet in a protruding chevron shape, allowing for easy peeling and attachment of outer end portions to an article without the need for individual folding, utilizing a label supply unit, holding unit, folding and temporary attaching unit, and backing sheet conveyance unit to form and attach the label.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If labels are provided in a planar shape on a backing sheet, then the label sheet is easy to manufacture and store, but the attaching procedure becomes cumbersome and complicated requiring manual folding
Solution Approach 1:
The label is pre-formed with a folded portion creating a chevron-shaped protrusion and outer end portions before being attached to the backing sheet. This preliminary folding action eliminates the need for manual folding during the attaching procedure, resolving the contradiction between ease of manufacture and ease of operation.
2Device complexity
If labels are temporarily attached to a backing sheet in a planar state, then the label sheet is simple in structure, but individual folding is required before attachment increasing the attaching procedure complexity
Solution Approach 1:
The label structure is pre-configured with a folded portion forming a chevron-shaped protrusion and outer end portions that extend beyond the label body. This preliminary structuring allows the label to be directly attached to articles without additional folding steps, reducing operation complexity while maintaining label sheet simplicity.
3Reliability
If manual folding is required to form the chevron shape, then the label can be attached to articles, but the attaching procedure is time-consuming and inefficient
Solution Approach 1:
The label is manufactured with a folded portion already forming the chevron-shaped protrusion and outer end portions in the correct configuration. This preliminary formation ensures reliable attachment to articles while eliminating time-consuming manual folding operations, thereby improving productivity without compromising attachment reliability.

AI summary
A label and label attaching device for attaching a label onto a backing sheet. The label has a protruding apex portion, side surfaces defined when the label is folded at the apex and end portions at the outer base ends of the side surfaces. A label sheet is formed by temporarily attaching labels to a backing sheet. Prior to attachment, an intermediate portion of the label protrudes from its back surface to its front surface in a folded chevron shape. Outer end portions of the side surfaces project out from the side surfaces and the outer end portions are temporarily attached to the backing sheet with the folded portion protruding. The attaching device has two divided bodies to which the outer end portions are temporarily attracted. The divided bodies are movable together and apart to define the folded label. Then the label holding unit moves the folded label to an attaching position on the backing sheet which is moving past.
