Vertically Movable Machine Paneling for Container Treatment Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Treatment machines for containers, such as labeling machines, face challenges in cleaning and maintenance due to the need for dismantling and reassembling machine casing segments to access areas underneath, which is labor-intensive and requires extensive securing mechanisms to prevent unauthorized access during operation.
Innovation Solution
A treatment machine design featuring a rotatable container table with lateral anti-lift covering and vertically movable machine casing segments, where the anti-lift paneling acts as a mechanical stop and allows the machine paneling to be easily pushed up for maintenance and cleaning without tools, eliminating the need for extensive disassembly and securing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine casing segments are bolted to the base frame and secured with safety contacts, then safety and security during operation are improved, but cleaning effort and device complexity increase
Solution Approach 1:
The machine casing is divided into multiple segments that can be independently moved vertically. Each segment can be raised separately to access specific areas for cleaning, while remaining segments stay secured. This segmentation allows safety contacts to be simplified since not all segments need simultaneous securing, and cleaning effort is reduced by accessing only the necessary areas.
Solution Approach 2:
The machine casing segments are designed with dynamic positioning capability, allowing them to be moved between a lowered operating position (secured for safety) and a raised maintenance position (accessible for cleaning). This dynamic behavior eliminates the need for permanent bolting and multiple safety contacts, reducing device complexity while maintaining safety during operation.
2Reliability
If machine casing segments are bolted and secured with safety contacts, then security during operation is improved, but cleaning time and effort increase
Solution Approach 1:
The machine casing segments can be dynamically raised to a maintenance position without complete disassembly. This eliminates the time-consuming process of unscrewing and reassembling bolted connections, reducing cleaning time from potentially hours to minutes while maintaining security during operation through the lowered position.
Solution Approach 2:
The machine casing segments are extracted from the fixed bolted configuration and converted into movable components. This extraction allows the segments to be raised independently for cleaning without affecting the overall structural integrity or security of the machine during operation.
3Reliability
If multiple safety contacts are installed on machine casing segments, then unauthorized removal prevention is improved, but device complexity and securing effort increase
Solution Approach 1:
By segmenting the machine casing into movable sections, the number of safety contacts required is reduced. Instead of securing multiple bolted segments with individual safety contacts, only the raised segments need monitoring, simplifying the securing equipment while maintaining unauthorized removal prevention.
Solution Approach 2:
The dynamic raising and lowering of casing segments reduces the need for extensive securing equipment. When segments are lowered, they are naturally secured by gravity and the machine structure itself, reducing reliance on additional safety contacts and complex securing mechanisms.

AI summary
A treatment machine for containers, particularly bottles, is described, comprising: a rotatable container table; at least one lifting protection guard extending laterally around the container table; and at least one lateral machine guard attached to a base frame below the lifting protection guard. According to the invention, the machine guard can be vertically displaced on the base frame. This allows access to an area below the treatment machine for cleaning purposes without disassembling the machine guard.
