Label Affixing Device Cutter Peeling Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional label printing devices require a large configuration to prevent label paper from sticking to the cutting unit, making them bulky and inefficient.
Innovation Solution
A label affixing device with a printer, cutter, peeling part, and affixing part, where the cutter is positioned upstream of the peeling part, allowing the label to remain attached to the release material until peeling, eliminating the need for a configuration to prevent sticking and enabling a more compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cutting unit is positioned downstream relative to the peeling part, then the label can be cut after peeling, but the label may stick to the cutting unit requiring additional preventive configurations that increase device size
Solution Approach 1:
The cutting operation is performed before the peeling operation, so the label is already separated from the continuous tape before it is peeled from the release material. This preliminary cutting action eliminates the risk of the label sticking to the cutting unit after peeling, as the cutting blade no longer contacts the peeled label. The device achieves compactness by positioning the cutting unit upstream of the peeling part in the conveying direction.
Solution Approach 2:
The conventional sequence of operations (peeling then cutting) is inverted to (cutting then peeling). By reversing the order of these two operations, the patent eliminates the technical problem of label sticking to the cutting unit, as the label is already cut into individual pieces before peeling occurs, so there is no continuous label surface to stick to the cutting blade.
2Device complexity
If the peeling part is positioned upstream relative to the cutter, then additional configurations are needed to prevent label sticking, but if the cutter is upstream, the device can be more compact
Solution Approach 1:
The cutting operation is performed in advance before peeling, so the label is already separated from the continuous tape. This preliminary action eliminates the need for complex anti-sticking configurations between the peeled label and cutting unit, simplifying the overall device configuration while enabling compact design.
3Manufacturing precision
If the cutter cuts through the release material, then complete separation is achieved, but the release material cannot be reused and additional material is wasted
Solution Approach 1:
The cutting operation is applied locally only to the label portion of the tape, not through the entire laminated structure. The half-cutting mechanism cuts through the base material and adhesive layer but stops before penetrating the release material, creating a localized cut that separates the label while preserving the release material for potential reuse or clean disposal.
Solution Approach 2:
Instead of performing a full cut through all layers (excessive action), the cutting mechanism performs a partial cut that stops at the adhesive layer. This partial cutting action is sufficient to separate the label from the continuous tape while avoiding damage to the release material, thereby reducing material waste.

AI summary
In a label affixing device, a printer performs printing on a tape. The tape includes: a base material; and a release material. The base material has an adhesive surface and a printing surface. The release material covers the adhesive surface. A cutter is disposed downstream relative to the printer in a conveying direction of the tape, and cuts a prescribed portion of the tape while leaving the release material intact to produce a label having the printing surface on which printing has been performed by the printer. A peeling part is disposed downstream relative to the cutter in the conveying direction of the tape, and peels the label off the release material. An affixing part is disposed downstream relative to the peeling part in a conveying direction of the label, and affixes the label peeled off the release material by the peeling part to an adherend.
