Cable Label Wrapping with Full Peel-Off Before Insertion

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing label applicators fail to reliably wrap labels around cables due to incomplete separation of labels from the release paper during the wrapping process, resulting in improper label application.

Innovation Solution

A label wrapping device with a stripping part, conveying roller, insertion recess, and controller that ensures complete separation of labels from the release paper before wrapping by controlling the conveying roller to halt conveyance when the label is fully peeled off and positioned to cover the insertion recess opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the label stripper assembly separates labels from the liner member one label at a time during cable conveyance, then the labeling process can proceed continuously, but the label may not completely separate from the liner member resulting in improper label wrapping

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The label is completely peeled off the release paper in advance by the stripping part before the wrapping operation begins. The conveying roller halts conveyance when the upstream end of the label becomes positioned downstream relative to the stripping part and after the label covers at least a portion of the opening of the insertion recess, ensuring complete separation is achieved before wrapping starts.

2Device complexity

If the gripper assembly moves the cable toward the puck assembly while the label stripper peels off the label, then the wrapping process can be integrated, but the label separation may be incomplete during the wrapping operation

Engineering Contradiction:

Improveintegrated wrapping processVSAvoidlabel separation completeness

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The stripping part completely peels off the label from the release paper before the wrapping operation begins. The controller halts the conveying roller when the label covers at least a portion of the opening of the insertion recess, ensuring complete separation is achieved in advance before the cable is introduced and wrapping commences.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The labeling process is divided into distinct sequential stages: first the stripping part completely separates the label from the release paper, then the conveying roller halts when the label is properly positioned, and finally the wrapping operation proceeds. This segmentation ensures complete separation is achieved before wrapping begins.

AI summary

A label wrapping device configured to warp a label around a cable includes a stripping part, a conveying roller, an insertion recess, a driving part and a controller. The conveying roller conveys the label peeled off a release paper by the stripping part in a conveying direction along a conveying path. The insertion recess is positioned downstream of the conveying roller in the conveying direction and is open toward the conveying path. The controller is configured to control the driving part: (a) to enable the conveying roller to convey the label peeled off the release paper in the conveying direction; and (b) to enable the conveying roller to halt conveyance of the label when an upstream end of the label becomes positioned downstream relative to the stripping part in the conveying direction and after the label covers at least a portion of an opening of the insertion recess.
