Vent Tube Quick-Connect Locking for Faster Bottling Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vent tubes in bottling machines are time-consuming to change, often resulting in significant downtime due to the need for tools, risk of damage, and improper installation, especially in high-speed bottling operations.
Innovation Solution
A quick connect mechanism featuring a vent tube with protrusions that engage with a receiver having recesses and a spring-based locking system, allowing for rapid attachment and detachment without the need for tools, while ensuring secure and correct installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded attachment methods are used for vent tubes, then the connection can be secure, but the changing process becomes time-consuming and requires tools
Solution Approach 1:
The connection system is divided into separate components: a valve insert with internal threading and a vent tube with external threading. This segmentation allows the vent tube to be quickly attached and detached without requiring the entire assembly to be disassembled, reducing changing time while maintaining secure connection through the threaded interface.
Solution Approach 2:
The vent tube connection system transitions from a static threaded connection to a dynamic quick-connect mechanism. The vent tube can be rapidly inserted and rotated into place, then quickly removed when needed, making the connection system adaptable and flexible for frequent changes without requiring tools or complex operations.
2Reliability
If threaded attachment methods are used for vent tubes, then the connection can be secure, but the operation becomes complex requiring tools and proper technique
Solution Approach 1:
The vent tube is pre-threaded with external threads that match the internal threads of the valve insert. This preliminary preparation allows the operator to simply align and rotate the vent tube into place without requiring additional tools or complex assembly steps, making the operation straightforward and reducing the risk of improper installation.
Solution Approach 2:
Instead of requiring the operator to screw the vent tube in using tools, the design inverts the approach by having the vent tube simply rotate into place through hand operation. The threading is designed so that the natural rotation motion during insertion automatically secures the connection, eliminating the need for wrenches or other tightening tools.
3Ease of operation
If press fit configuration is used for vent tubes, then tool-free installation is achieved, but the vent tubes become difficult to remove and insert
Solution Approach 1:
The connection system is divided into separate components: a valve insert with internal threading and a vent tube with external threading. This segmentation allows the vent tube to be quickly attached and detached without requiring the entire assembly to be disassembled, reducing changing time while maintaining secure connection through the threaded interface.
Solution Approach 2:
The vent tube connection system transitions from a static threaded connection to a dynamic quick-connect mechanism. The vent tube can be rapidly inserted and rotated into place, then quickly removed when needed, making the connection system adaptable and flexible for frequent changes without requiring tools or complex 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 quick and secure connection of vent tubes to valve inserts, reducing downtime during product line changes, minimizing the risk of damage and improper installation, and improving overall efficiency in bottling operations.
Implementation Method 1
a spring positioned within the receiver between the gas stem base and the vent tube and configured to bias the protrusion against the recess
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.
