Vent Tube Quick-Connect Locking for Bottling Machine Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vent tube connection methods in bottling machines, such as threaded and press fit attachments, are time-consuming, prone to damage, and result in significant downtime due to the need for tools, over-torquing, and potential for improper installation, leading to lost vent tubes during production.
Innovation Solution
A quick connect mechanism featuring a receiver with a spring-based locking system and protrusions that allow for easy attachment and detachment of vent tubes, preventing unintentional removal and enabling rapid changeovers without tools, using a bayonet latch mechanism for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded attachments are used to connect vent tubes to valve inserts, 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 internal threading and a vent tube with external threading. This segmentation allows the vent tube to be quickly screwed into the valve insert without requiring complex tools or mechanisms, resolving the contradiction between secure connection and quick changeover.
Solution Approach 2:
Instead of using a complex locking mechanism to secure the vent tube, the patent inverts the approach by using a simple threaded connection that relies on the natural friction and mechanical interference of the threads themselves. This inversion simplifies the connection method while maintaining security, eliminating the need for additional tools or locking components.
2Ease 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 may slip out or fall into bottles
Solution Approach 1:
The vent tube is pre-threaded with external threads before installation. This preliminary preparation allows the tube to be quickly screwed into the valve insert without requiring tools during the actual installation process. The pre-threaded design enables tool-free operation while maintaining secure connection through the threaded interface.
Solution Approach 2:
The patent replaces the press-fit mechanical system with a threaded mechanical system. Instead of relying on friction and interference fit, the connection is achieved through screw threads that provide both ease of installation and secure retention. This substitution eliminates the problems of difficult removal and accidental dislodgement associated with press-fit configurations.
3Reliability
If threaded vent tubes are tightened with tools, then secure connection is achieved, but over torqueing can damage the valve cover
Solution Approach 1:
The threaded connection is designed to be self-limiting, where the threads naturally engage and lock together without requiring external torque application. The mechanical interference of the threads provides sufficient friction to maintain secure connection without the need for over-torquing, thereby preventing damage to the valve cover while achieving reliable connection.
4Reliability
If conventional threaded or press fit methods are used, then vent tubes can be connected, but the process is slow and causes significant downtime during production changeovers
Solution Approach 1:
The patent changes the connection parameter from complex multi-step processes (tool-based threading or press-fit alignment) to a simple manual screw-in operation. This parameter change reduces the time required for connection while maintaining stability, thereby improving bottling line efficiency during changeovers without sacrificing connection reliability.

AI summary
A method of connecting a vent tube to a bottling machine comprising providing a vent tube having a vent tube alignment mechanism, a receiver defining a through-opening and a receiver alignment mechanism, and a biasing mechanism for biasing against at least a portion of the vent tube. Aligning the vent tube with the through-opening and the vent tube alignment mechanism with the receiver alignment mechanism, inserting the vent tube into the receiver against the biasing mechanism, rotating the vent tube such that the vent tube alignment mechanism is not aligned with the receiver alignment mechanism, and locking the vent tube to the receiver using the biasing mechanism to bias the vent tube alignment mechanism out of alignment with the receiver alignment mechanism to form a positive locking feature that keeps the vent tube connected to the receiver throughout bottling machine operations.
