Container Guide Emergency Cam Lift for High-Speed Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container treatment systems face challenges in achieving higher throughput rates due to the potential failure of spring elements to timely return containers from the treatment position to the release position, leading to operational interruptions and potential damage, especially at increased speeds.
Innovation Solution
Incorporation of an emergency lifting device with adjusting cams on the rotatable support to ensure containers are returned to the release position even if the spring elements fail, using a cam-controlled mechanism to engage the container guide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rotatable carrier operates at higher speed to increase throughput, then productivity is improved, but the spring element cannot timely return the container guide to the release position, causing operational interruptions
Solution Approach 1:
The adjusting cam is pre-configured with a height profile that provides emergency lifting capability before spring element failure occurs. This passive mechanical backup ensures that even when the spring element fails to return the container guide timely at high speeds, the adjusting cam can force the return to the release position, preventing operational interruptions and maintaining reliability while enabling higher productivity
Solution Approach 2:
The adjusting cam acts as an intermediary mechanism between the rotatable carrier's rotation and the container guide's vertical movement. It translates the rotational motion into vertical lifting motion that complements the spring element's function, ensuring reliable return of the container guide even when operating at higher speeds that exceed the spring element's capability alone
2Reliability
If the spring element force is increased to ensure timely return at higher speeds, then reliability is improved, but the contact force pressing containers against the fluid outlet increases, potentially causing damage
Solution Approach 1:
The adjusting cam provides a pre-configured mechanical backup that limits the maximum contact force applied to containers. By engaging the adjusting cam's height profile, the system ensures timely return without requiring excessive spring force, thus preventing damage to containers while maintaining reliability at higher operating speeds
Solution Approach 2:
The adjusting cam serves as a force-limiting intermediary that mediates between the spring element and the container guide. It ensures that the contact force remains within safe limits while still achieving the necessary return motion, preventing container damage even when reliability is compromised by wear or high-speed operation

Function Achieved in This Case
Ensures reliable and timely return of containers to the release position, preventing operational interruptions and potential damage, thereby enabling higher throughput without requiring costly plant redesign.
Implementation Method 1
the lifting return via the spring element in particular enables reliable operation and the speed of the return can be selected solely based on the spring constant of the spring element
Implementation Method 2
at least one adjusting cam is arranged in an end section on the rotatable support and can be brought into cooperative engagement with the container guide for the lifting-movable return
