Overlapping Straightening Members for Curl-Free Cable Label Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label wrapping devices struggle with curling tendencies of labels, leading to unstable wrapping around cables.
Innovation Solution
A label wrapping device with a conveying roller and a straightening member, comprising overlapping first and second members, corrects curling by deforming labels into a wavy shape before wrapping, ensuring secure adherence to cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the label is maintained in a rolled state, then the label can be stored and conveyed efficiently, but the label develops a curling tendency that prevents secure wrapping around the cable
Solution Approach 1:
The straightening member performs preliminary action by correcting the curling tendency of the label before the label reaches the wrapping position. The straightening member includes a first member and a second member that are positioned to apply corrective force to the label in its rolled state, eliminating curling before wrapping occurs, thus ensuring reliable wrapping while maintaining efficient conveying
2Ease of operation
If the label is peeled off the liner member, then the label can be applied to the cable, but the label curls immediately after peeling which compromises wrapping security
Solution Approach 1:
The straightening member acts as an intermediary between the label stripper assembly and the wrapping position. It receives the label immediately after peeling from the liner member and applies a straightening action to eliminate curling before the label proceeds to the wrapping position, thus ensuring both ease of operation and manufacturing precision
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 device effectively stabilizes the wrapping process by correcting label curling, ensuring consistent and secure attachment of labels to cables.
Implementation Method 1
The straightening member includes a first member and a second member positioned opposite each other with respect to the conveying path in a prescribed direction intersecting the conveying path. A part of the first member and a part of the second member overlap each other in a width direction orthogonal to the conveying direction and crossing the prescribed direction.

AI summary
A label wrapping device configured to warp a label around a cable includes: a conveying roller, a straightening member and an insertion recess. The conveying roller conveys the label in a conveying direction along a conveying path. The straightening member is positioned downstream of the conveying roller in the conveying direction. The straightening member includes a first member and a second member opposing each other across the conveying path in a prescribed direction intersecting the conveying path. A part of the first member and a part of the second member overlap each other in a width direction orthogonal to the conveying direction and crossing the prescribed direction. The insertion recess is positioned downstream of the straightening member in the conveying direction and on the same side as the second member in the prescribed direction with respect to the conveying path. The insertion recess is open toward the conveying path.
