Label Printer Cover Segmentation for Peel Mode Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional label printers face operability issues when switching between continuous and removal issuing modes, particularly in the continuous issuing mode, where the label paper needs to be inserted into a paper exit opening, making the process less user-friendly and increasing design and production costs due to asymmetric cover designs.
Innovation Solution
A label printer design featuring a printer body with a paper roll holder, a label printing unit, a platen roller, a cover that opens or closes, and a removal unit with a pivotally supported removal roller and sensors, allowing for separate operation of the removal unit and easy maintenance, and a detachable configuration that improves operability and balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is designed to open in a lateral direction to improve operability in removal issuing mode, then the operability is improved, but the balance of left and right portions deteriorates and the cover becomes difficult to open
Solution Approach 1:
The cover is divided into a main body portion and a detachable removal unit portion. The removal unit can be separated from the main cover body, allowing independent operation and maintenance of each component. This segmentation resolves the contradiction by enabling improved operability in removal issuing mode without compromising the overall structural balance and ease of opening the main cover.
Solution Approach 2:
The cover transitions from a static, fixed structure to a dynamic, reconfigurable structure. The removal unit can be attached or detached based on operational needs, allowing the cover to adapt its configuration. This dynamic design enables improved operability when needed while maintaining structural balance during normal operation.
2Ease of operation
If the cover design is made asymmetric to accommodate removal unit, then the operability is improved, but the design and production costs increase
Solution Approach 1:
By segmenting the cover into modular components (main body and removal unit), the design achieves operational improvements without requiring fully asymmetric manufacturing. The modular structure allows standardized production of individual components that can be assembled, reducing overall design and production complexity compared to a fully asymmetric monolithic design.
Solution Approach 2:
The main cover body is designed with universal features that can accommodate both symmetric and asymmetric configurations. The standardized interface for the removal unit allows the same main body to work with different configurations, reducing the need for entirely different production lines and lowering manufacturing costs.
3Ease of operation
If the removal roller is pressed against the platen roller only after cover closure, then the operability is good in removal issuing mode, but the switching between modes becomes more complex
Solution Approach 1:
The removal roller is integrated into a separate, detachable removal unit rather than being fixed to the main cover body. This segmentation allows the removal roller to be positioned and pressed against the platen roller independently, simplifying the switching mechanism. Users can attach the removal unit when needed and detach it otherwise, without complex mechanical switching mechanisms.
Solution Approach 2:
The removal unit transitions from a fixed state to a detachable state based on operational needs. This dynamic configuration allows the removal roller to be engaged or disengaged from the platen roller through simple attachment and detachment actions, rather than through complex mechanical switching mechanisms.
4Adaptability or versatility
If the label paper is inserted into the paper exit opening for continuous issuing mode, then the continuous issuing function is achieved, but the operability deteriorates
Solution Approach 1:
The cover is segmented into a main body and a removable unit, allowing users to detach the removal unit when using continuous issuing mode. This eliminates the need to insert label paper through a narrow exit opening, as the paper can be loaded directly into the paper roll holder with the removal unit detached, significantly improving operability while maintaining the continuous issuing function.
Solution Approach 2:
The cover configuration dynamically changes based on the issuing mode. When continuous issuing is needed, the removal unit is detached, creating an open loading path for paper insertion. When removal issuing is needed, the removal unit is attached, providing the necessary constraints. This dynamic reconfiguration simplifies the paper loading process for continuous mode without compromising the removal issuing capability.

Implementation Method 1
a removal roller (21) that sends the paper strip in a second direction that is different from the first direction in such a way that the paper strip is being held between the removal roller (21) and the platen roller (16), and peels off the label from the paper strip
Implementation Method 2
a platen roller (16) that sends the paper strip in a first direction after the paper strip passes through the print head
Implementation Method 3
a label printing unit (12) that includes a print head to print a label that remains temporarily attached to a paper strip

AI summary
A label printer (1) is provided with a printer body (10) that includes a paper roll holder (11); a label printing unit (12) that includes a print head (26); a platen roller (16) that sends the paper strip (3) in a first direction after the paper strip (3) passes through the print head (26); a cover (13) that opens or closes the paper roll holder (11); and a removal unit (14) that peels off the label (4) from the paper strip (3). One end of the cover (13) is pivotally supported on the printer body (10) via a first rotation shaft (13a) that is parallel to a central axis of the paper roll (2). One end of a longitudinal side of the removal unit (14) is pivotally supported on the cover (13) via a second rotation shaft (14a) that is perpendicular to the first rotation shaft (13a). A locking mechanism (25) that engages with the cover (13) is provided at the other end of the longitudinal side of the removal unit (14).
