Label Feeding Machine Sensor Cover Detachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label feeding machines face difficulties in easily removing jammed labels that curl up and attach to the opening/closing member, leading to reduced workability and increased complexity in removal processes.
Innovation Solution
The label feeding machine incorporates a design with a detachable cover for the opening/closing member, featuring a surface resistant to adhesive sticking and a latching mechanism for easy installation and detachment, allowing for external removal of jammed labels and improved operational convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the gap between the support member and opening/closing member is reduced to improve detection accuracy, then sensor detection accuracy is improved, but label jamming occurs because the label curls up and attaches to the opening/closing member
Solution Approach 1:
The opening/closing member is divided into a main body and a detachable cover. The cover can be removed to provide access to the sensor and conveyance passage, allowing label removal without requiring complete disassembly of the detection mechanism. This segmentation enables the gap to be reduced for better detection while maintaining ease of label removal through cover detachment.
Solution Approach 2:
The cover is designed as a detachable component that can be separated from the main body of the opening/closing member. This extraction of the cover allows operators to access and remove jammed labels from the conveyance passage without affecting the sensor's positioned detection accuracy, effectively separating the detection function from the access function.
2Device complexity
If the opening/closing member is designed as a single integrated component, then structural simplicity is maintained, but label removal becomes difficult when labels attach to the hinge area
Solution Approach 1:
The opening/closing member is segmented into a main body containing the hinge and sensor, and a detachable cover. This segmentation allows the cover to be removed for label access while the main body remains intact, solving the problem of difficult label removal from hinge areas without over-complicating the overall structure.
Solution Approach 2:
The cover is extracted as a separate detachable component from the main body. This extraction enables easy access to labels that may have attached to the hinge area or deeper inside the conveyance passage, while the main body's integrated structure is preserved for structural support and sensor housing.
3Ease of operation
If adhesive-resistant coating is applied to the opening/closing member surface, then label attachment is prevented, but manufacturing complexity increases
Solution Approach 1:
Adhesive-resistant coating is applied locally to specific surfaces of the opening/closing member where labels are most likely to attach, particularly the inner surfaces of the cover and main body that form the conveyance passage. This localized application prevents label attachment problems without requiring complete coating of the entire component, thereby limiting the increase in manufacturing complexity to only the necessary areas.

AI summary
A label position detector has a sensor, a support member configured to support a strip-shaped liner sheet of a continuous label body, and an opening/closing member provided openably or closably against the support member. The opening/closing member has a main body installed with the sensor and a cover provided with a slot that causes the sensor to face the conveyance passage for the continuous label body and detachably installed on the main body.
