Bottle Cleaning Machine Label Removal Pre-Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle cleaning machines face challenges in reliably removing labels due to label parts getting caught in chain guides and being carried away in subsequent baths, leading to inefficiencies in label removal and increased load on subsequent treatment zones, especially at higher throughput speeds.
Innovation Solution
A first active device for label removal with a specifically directed flow from top to bottom is implemented in the pre-soaking bath immediately after bottle feeding, with the liquid level set above the bottle cells and an active flow for discharging labels into a special channel, reducing the load on subsequent zones and enhancing sedimentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single main flow channel is used to guide labels into the flow channel, then label removal effectiveness is improved, but a very high pump output is required and the effect can only be ensured up to a certain throughput speed
Solution Approach 1:
The patent divides the label removal process into multiple stages: pre-separation in the pre-soaking bath, then collection and removal in subsequent baths. This segmentation allows each stage to handle specific aspects of label removal, reducing the burden on any single pump and allowing operation at higher throughput speeds without requiring excessively high pump output.
Solution Approach 2:
The patent implements a pre-separation stage in the pre-soaking bath where labels are loosened and partially removed before the main cleaning process. This preliminary action reduces the amount of work required in subsequent stages, allowing the system to maintain effective label removal at higher throughput speeds with moderate pump output.
2Productivity
If the throughput speed of receiving cells is increased, then productivity is improved, but the impulse-like flows can no longer achieve their full effect on label removal
Solution Approach 1:
The patent creates continuous flows in the pre-soaking bath that act on labels throughout the bottles' passage, rather than relying on intermittent impulse flows. This continuous action ensures labels are consistently loosened and removed even at higher throughput speeds, maintaining reliability while increasing productivity.
Solution Approach 2:
By performing preliminary label loosening in the pre-soaking bath before the main cleaning process, the system ensures labels are pre-treated and easier to remove in subsequent stages, allowing the overall system to operate at higher throughput speeds without sacrificing label removal effectiveness.
3Reliability
If labels are removed in subsequent baths after chain guides, then label removal occurs, but label parts get caught in chain guides and are carried away in subsequent baths
Solution Approach 1:
The patent removes labels in the pre-soaking bath before bottles enter the chain guide system. By performing this preliminary removal action, labels are detached and collected in the pre-soaking bath's flow channel, preventing them from being caught in chain guides later in the process.
Solution Approach 2:
The patent extracts labels from bottles in the pre-soaking bath using specifically directed flows that carry labels into a dedicated flow channel. This extraction occurs before bottles proceed to subsequent treatment zones, separating the label removal function from the main cleaning process and preventing labels from interfering with chain guides.
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
This configuration ensures intensive pre-separation of labels and dirt particles, significantly reducing the load on subsequent soaking and bathing zones and improving label removal efficiency, even at higher throughput speeds.
Implementation Method 1
a first active device for label removal with a specifically directed flow is arranged in a presoaking bath immediately after the bottle is fed in. This flow can be directed, for example, from top to bottom
Implementation Method 2
Another advantage is the active flow in the direction of sedimentation to divert the labels and the like from top to bottom into a special flow channel

AI summary
The machine has a set of processing compartments arranged in series in a process flow direction. Bottles are passed in bottle cells or other transport systems by presoaked baths (10), brine baths and spraying stations of the compartments. Device for removing labels works together with the individual bottles. An active arrangement for label removal with specifically directed fluid flow is provided in the presoaked bath that follows directly towards a bottle feeding.
