Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label ejection devices cause vibrations and interruptions in the labeling process, leading to damage of the supporting tape and inaccurate label positioning, resulting in inefficient removal of faulty labels and potential costly recalls in industries like food and pharmaceutical packaging.
Innovation Solution
A label ejection device with an adhesive portion that adheres to the label border, allowing for smooth and vibration-free removal of labels of various sizes, coupled with a collecting mechanism that uses a pressing roller to transfer labels to a collecting tape, ensuring efficient and precise label disposal without tape damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing label ejection devices are used to remove faulty labels, then label removal is achieved, but vibrations and interruptions occur causing tape damage and positioning inaccuracies
Solution Approach 1:
The patent replaces traditional mechanical ejection mechanisms (peel plates, sharp edges, friction-based separation) with an adhesive-based removal system. The adhesive portion is applied to the label surface and then gently peeled away, eliminating the need for forceful mechanical separation that causes vibrations and tape damage.
Solution Approach 2:
The invention changes the physical state and properties of the removal mechanism by using adhesive materials with specific tack and bonding characteristics. The adhesive portion is applied in a controlled manner and then removed by peeling, changing the interaction from mechanical force to adhesive bonding and debonding, which reduces harmful vibrations.
2Productivity
If traditional peel plates or separating means are used, then label separation is achieved, but supporting tape damage and positioning inaccuracies occur
Solution Approach 1:
The patent substitutes mechanical peel plates and separating means with an adhesive portion that bonds to the label and is then gently peeled away. This adhesive-based approach maintains separation efficiency while eliminating the sharp edges and excessive force that cause positioning inaccuracies and tape damage.
Solution Approach 2:
The adhesive portion acts as an intermediary between the ejection device and the label. Instead of direct mechanical contact between the peel plate and label, the adhesive serves as a mediating element that transfers the removal action gently, preserving label positioning accuracy and preventing tape damage.
3Object-affected harmful factors
If adhesive portion is used to remove labels, then vibration-free removal is achieved, but label collection and transfer efficiency must be maintained
Solution Approach 1:
The adhesive portion serves as an intermediary that not only removes the label without vibrations but also facilitates efficient transfer to the collection mechanism. The adhesive bonds the label during removal and then releases it onto the collection tape or receptacle, maintaining productivity throughout the entire process.
Solution Approach 2:
The invention implements an efficient label collection system that recovers removed labels for proper disposal or recycling. The adhesive portion enables smooth transfer of removed labels to the collection mechanism, ensuring that the vibration-free removal process is complemented by efficient label recovery and disposal.

AI summary
The invention relates to a label ejection device (101,201,301,401,501,601,1201,1301), a labeling printing system comprising said device and a method for discarding labels, in particular self-adhesive labels (103,203,303,403,603). The invention is concerned in particular with preventing faulty labels from being applied to items (or containers containing such items), with minimal attendant interruption of machine operation. The effective labeling systems and equipment are not perfect and, on occasion, “incorrect” or faulty labels (103,203,303,403,603) may be applied to containers. There is a need for an improved label ejection device (101,201,301,401,501,601,1201,1301) and an improved labeling printing system that more efficiently and effectively removes labels (103,203,303,403,503,603) from a sheet like support (104,204,304,404,504,604,1204). An object of the present invention is to improve the apparatuses, systems and methods for discarding and collecting labels, in particular self-adhesive labels (103, 203, 303, 403, 503, 603).
