Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labelling modules are complex, requiring precise synchronization of multiple components and complicated vacuum systems, and lack flexibility in adapting to label format changes.
Innovation Solution
A labelling module with a simplified architecture that uses a transfer drum with integrated cutting and gluing, eliminating the need for a counterblade roller and allowing for interchangeable receiving sectors and improved web tensioning, enabling flexible adaptation to different label formats without requiring extensive reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional labelling module with separate cutting unit and counterblade roller is used, then the web can be supported and advanced, but the device complexity increases and synchronization becomes difficult
Solution Approach 1:
The patent combines the cutting unit and counterblade roller into a single integrated component. The cutting unit includes a blade element and a surface element that work together as one assembly, eliminating the need for separate counterblade rollers and reducing the number of synchronized moving parts while maintaining web support and cutting functions
2Manufacturing precision
If multiple components with precise synchronization are used, then cutting and label application can be performed, but the difficulty of detecting and measuring increases
Solution Approach 1:
By merging the cutting and support functions into a single integrated unit with the blade element and surface element, the patent reduces the number of components that need synchronization. The integrated design simplifies the control system while maintaining precise cutting through the coordinated movement of blade and surface elements within the same unit
3Manufacturing precision
If a conventional cutting unit with counterblade roller is used, then the web can be cut, but the adaptability to label format changes decreases
Solution Approach 1:
The patent implements a dynamic cutting unit where the blade element and surface element can be adjusted relative to each other. The cutting unit is designed to accommodate different web widths and label formats through adjustable positioning mechanisms, allowing the blade and surface elements to be repositioned to maintain optimal cutting geometry for various label sizes and shapes
4Manufacturing precision
If separate cutting unit and counterblade roller are used, then cutting can be performed, but the quantity of components increases
Solution Approach 1:
The patent merges the cutting unit with the counterblade function into a single integrated component. The cutting unit includes both the blade element for cutting and the surface element that performs the counterblade support function, thereby eliminating the need for a separate counterblade roller and reducing the total component count while maintaining both cutting and support capabilities
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 reduces component complexity, enhances flexibility and adaptability, and improves cutting precision and label application quality, particularly for partial labels, without the need for cumbersome reassembly or additional vacuum systems.
Implementation Method 1
a label transfer device, for example a known vacuum drum configured to receive, retain and advance each label and to feed each label to the carousel
Implementation Method 2
for spreading glue onto at least the (leading and trailing) edges of each single label, prior to their application onto the relative articles
Implementation Method 3
the sleeve labels are applied with a certain clearance on the respective articles and then heated in an oven to obtain their shrinking and perfect adhesion

AI summary
Provided is a labelling module for labelling containers adapted to contain a pourable product, the labelling module having a feed roller for advancing a web of labelling material along a feed path; a cutting member downstream of the feed roller, for repeatedly cutting the web to separate a sequence of labels therefrom; and a transfer drum rotatable about a rotation axis in an angular direction of rotation, and configured to transfer the labels to an application station for the application thereof onto the respective containers; the transfer drum includes a plurality of receiving sectors each configured to cyclically receive and retain a label, the receiving sectors including, a leading pad for retaining a leading edge of the label and a trailing pad for retaining a trailing edge of the label.
