Label Peeling Unit with Movable Body for Easy Paper Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label peeling units are difficult to insert paper sheets due to the close proximity of peeling parts and rollers, making it challenging to facilitate easy insertion.
Innovation Solution
A label peeling unit with a movable body that can shift parallel and rotate relative to an attachment body, equipped with a label peeling body and a mount sheet conveying roller, allowing for easy insertion and peeling of labels by bending the mount sheet and conveying it outside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the peeling part and rollers are positioned close to each other in a compact structure, then the device complexity is reduced, but the ease of operation deteriorates due to difficulty in inserting paper sheets
Solution Approach 1:
The movable body is designed to shift between a closed state (for compact operation) and an open state (for easy paper sheet insertion). The spring mechanism enables automatic transition between these states, allowing the device to maintain compactness during operation while facilitating easy insertion when needed.
Solution Approach 2:
The spring is pre-loaded to automatically open the movable body when a paper sheet is inserted, eliminating the need for manual opening operations. This preliminary action prepares the device for easy paper sheet insertion without requiring additional user effort.
2Ease of operation
If the movable body is designed to shift and rotate freely, then the ease of operation improves for paper sheet insertion, but the device complexity increases due to additional movement mechanisms
Solution Approach 1:
The movable body incorporates both parallel shifting and rotational capabilities through a unified spring-driven mechanism. This dynamic design allows the body to automatically adjust its position and orientation to accommodate paper sheet insertion while maintaining overall structural simplicity.
Solution Approach 2:
The parallel shifting and rotational movements are combined into a single movable body mechanism driven by one spring. This merging of multiple movement functions into one integrated component reduces the overall complexity compared to having separate mechanisms for each movement type.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables easy insertion of paper sheets and efficient peeling of labels by allowing parallel shifting and rotational movement of the movable body, improving the usability of the label peeling unit.
Implementation Method 1
a movable body (52) being movable while engaging with the attachment body (51), the movable body (52) being urged by a spring (61)
Implementation Method 2
a label peeling body (53), fitted to the movable body (52) and contacted by the mount sheet of the continuous label strip conveyed by the paper sheet conveying device so that the mount sheet is bent, to thereby peel a portion of a label from the mount sheet
Implementation Method 3
a mount sheet conveying roller (54), attached to the movable body (52) freely rotatably, and rotating while being in contact with a platen roller of the paper sheet conveying device via the mount sheet, to thereby convey the mount sheet and discharge it outside

AI summary
[Problem] Loading of paper sheets is made easy in a label peeling unit fitted to a label printer or the like and used for peeling labels from a mount sheet. [Solution] This label peeling unit has: an attachment body attached to a case of a paper sheet conveying device; a movable body being movable and engaging with the attachment body, the movable body being urged by a spring, whereby it stops in a closed state or in an open state with respect to the attachment body; a label peeling body, fitted to the movable body and contacted by the mount sheet of a continuous label strip conveyed by the paper sheet conveying device so that the mount sheet is bent, to thereby peel a portion of a label from the mount sheet; and a mount sheet conveying roller, attached to the movable body freely rotatably, and rotating while being in contact with a platen roller of the paper sheet conveying device via the mount sheet, to thereby convey the mount sheet and discharge it outside.
