Solution Overview
Problem
Existing container labeling machines with cutting and transfer drums face challenges in noise reduction during label cutting and adaptability to different label formats.
Innovation Solution
The labeling machine incorporates a cutting drum with suction ports and cutting devices equipped with blades supported by noise-attenuating blade supporting blocks, which feature cavities to reduce noise and facilitate easy format changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If suction chambers with blades are used to cut the label ribbon, then the labels can be cut and transferred effectively, but noise is generated during the cutting process
Solution Approach 1:
A blade supporting block is introduced as an intermediary component between the blade and the suction chamber. This block serves as a mediator that transmits the suction force to the blade while providing a structure to accommodate noise-reducing cavities, thus resolving the conflict between effective cutting and noise reduction
Solution Approach 2:
The blade supporting block incorporates cavities (void spaces) that function similarly to porous structures in absorbing and attenuating noise. These cavities reduce the noise generated during label cutting while maintaining the structural integrity and cutting effectiveness of the blade assembly
2Manufacturing precision
If multiple blades are provided on the cutting drum, then labels can be cut accurately, but the device complexity increases when changing label formats
Solution Approach 1:
The cutting system is segmented into modular blade supporting blocks that can be independently positioned and adjusted on the cutting drum. Each block can be individually configured for different label formats, allowing precise cutting while simplifying format changes through modular reconfiguration rather than redesigning the entire blade system
Solution Approach 2:
The blade supporting blocks are designed to be dynamically reconfigurable on the cutting drum surface. This allows the cutting system to adapt to different label formats by adjusting the position and configuration of the blocks, maintaining cutting accuracy while reducing the complexity of format changes

AI summary
A labeling machine includes a conveyor of containers to be labeled along an advancement path and at least one labeling station which is arranged along the advancement path of the containers. The labeling station supports at least one cutting device for the label ribbon. The cutting device includes a respective suction chamber which accommodates internally at least one blade. The suction chamber is connectable with an air suction device, in order to attract the label ribbon toward the inside of the suction chamber and against the blade and in so doing cutting the label ribbon. The cutting device includes at least one respective blade supporting block which is supported by the cutting drum and supports the blade. At least one portion of the blade supporting block is provided internally with at least one cavity for attenuating noise generated by cutting the label ribbon.
