Labeling Device Automated Label Roll Feeding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional labeling devices require manual operation to position and exchange label rolls, leading to inefficiencies in setting up and replacing consumed labels.
Innovation Solution
The labeling device incorporates a system with loading rollers, a guide unit, and a pivotable printing head to automatically pull out and feed the label holding band to the feeding rollers, eliminating the need for manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used to position and exchange label rolls, then the device structure can be simple, but the productivity and ease of operation deteriorate due to time-consuming manual setup
Solution Approach 1:
The label roll is pre-positioned on a rotating guide frame before the labeling operation begins. The guide frame automatically rotates to feed the label holding band into the labeling position, eliminating the need for manual positioning during operation. This preliminary setup enables continuous automated operation.
Solution Approach 2:
The system uses its own rotating guide frame mechanism to automatically feed and position the label holding band without external manual intervention. The guide frame self-regulates the feeding process by rotating to bring the label roll into the correct position and guiding the band through the labeling head.
2Ease of operation
If manual operation is used to position the leading edge of the label holding band, then the device structure can be simple, but the ease of operation deteriorates due to required operator intervention
Solution Approach 1:
The leading edge of the label holding band is pre-positioned on the rotating guide frame during label roll installation. The guide frame then automatically rotates to bring this pre-positioned leading edge into the feeding rollers, eliminating the need for manual edge positioning during operation.
Solution Approach 2:
The rotating guide frame acts as an intermediary mechanism between the label roll and the feeding rollers. It receives the label roll, automatically orients it, and feeds the leading edge to the rollers through controlled rotation, simplifying the overall feeding process.
3Productivity
If manual exchange of consumed label rolls is required, then the device structure can be simple, but the productivity deteriorates due to downtime during exchange
Solution Approach 1:
Multiple label rolls can be pre-loaded onto the rotating guide frame in advance. When one roll is consumed, the guide frame automatically rotates to present the next pre-positioned roll, enabling continuous operation without manual intervention or downtime.
Solution Approach 2:
The rotating guide frame maintains continuous operation by automatically transitioning between multiple pre-loaded label rolls. This ensures the labeling process never stops, as the guide frame continuously feeds fresh label rolls to the labeling head without requiring manual exchange or creating downtime.

AI summary
An object of the present invention solves the conventional problems and is to provide a labeling device which automatically pulls out a leading edge of a label holding band from a label roll, and brings the leading edge of the label holding to a feeding roller, without the operations of the operator, after putting the label roll on the labeling device. Means for Solution According to the present invention, labeling device comprising a guide frame rotatably supporting a label roll formed by winding around a core a label holding band which releasably holds a plurality of labels in series and a peeling member which peels the printed label from the label holding band by bending the label holding band at an acute angle towards a slanting lower part in relation to the direction of movement of the label holding band characterized in that the labeling device comprises a guide unit that is pivotally provided for nipping and holding a leading edge of the label holding band in front of the peeling member and is intended to be rotated around the peeling member with the nipped and held leading edge of the label holding band so that the leading edge of the label holding band is brought to a feeding roller arranged on the slanting lower part of the peeling member in relation to the direction of the movement of the label holding band.
