Vent Tube Receiver Locking for Faster Bottling Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vent tube connection methods in bottling machines, such as threaded and press fit configurations, are time-consuming, prone to damage, and result in significant downtime due to the need for tools, over-torquing, and the risk of improper installation and loss during operation.
Innovation Solution
A quick connect mechanism featuring a receiver with a spring-based locking mechanism and protrusions that engage with the vent tube, allowing for rapid attachment and detachment, ensuring secure and proper installation without the need for tools, and minimizing downtime during line changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded attachment methods are used for vent tubes, then the connection is secure, but the process becomes time-consuming and requires tools which are not readily available
Solution Approach 1:
The connection system is divided into separate components: a valve insert with external threads and a vent tube with internal threads. This segmentation allows the vent tube to be quickly attached and detached without requiring the entire assembly to be threaded together, reducing changeover time while maintaining secure connection through the threaded interface.
Solution Approach 2:
The vent tube is pre-threaded during manufacturing, so that when installation is needed, the threading operation is already prepared. This preliminary action eliminates the need for on-site threading operations and reduces the time required for changing vent tubes, as workers simply need to screw the pre-threaded tube into the valve insert.
2Reliability
If tools are used to tighten screw-in vent tubes, then the connection is secure, but damage can occur to the vent tube and over-torquing can damage the valve cover
Solution Approach 1:
The vent tube and valve insert are designed with self-aligning threaded features that guide the connection process. The internal and external threads are configured to automatically align during insertion, eliminating the need for tools to force the connection. This self-service mechanism prevents over-torquing and damage to both the vent tube and valve cover while ensuring secure connection.
3Ease of operation
If press fit configuration is used for vent tubes, then tool-free installation is achieved, but the vent tubes are difficult to remove and insert, especially in large bottling machines with many vent tubes
Solution Approach 1:
The connection system transitions from a static press-fit to a dynamic threaded connection that can be easily engaged and disengaged. The threaded interface allows workers to quickly screw in and screw out vent tubes without requiring excessive force or special tools, significantly improving the productivity of changing multiple vent tubes in large bottling machines while maintaining ease of operation.
4Productivity
If press fit vent tubes are used, then rapid installation is possible, but they can be installed incorrectly and slip out or fall into bottles during operation
Solution Approach 1:
The press-fit mechanical system is replaced with a threaded mechanical system that provides positive engagement through thread engagement. This substitution maintains the speed of installation while dramatically improving reliability, as the threaded connection prevents incorrect installation and secures the vent tube against slipping out or falling into bottles during high-speed bottling operations.
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 enables rapid and secure connection of vent tubes to gas stems, reducing downtime and preventing unintentional removal, thus improving the efficiency and reliability of bottling operations by ensuring proper installation and reducing the risk of lost parts.
Implementation Method 1
a spring positioned within the receiver between the gas stem base and the protrusion to bias the protrusion against the receiver
Data Source
AI summary
A gas stem assembly is disclosed including a vent tube having at least one protrusion extending radially from the vent tube and a receiver having a non-circular opening and an attachment surface at an end of the non-circular opening. The vent tube is at least partially insertable through the non-circular opening of the receiver when the vent tube and the at least one protrusion are aligned with the non-circular opening. The attachment surface of the receiver contacts the at least one protrusion to inhibit the at least one protrusion from passing back through the non-circular opening when the at least one protrusion is misaligned with the non-circular opening.
