Capping Machine Movable Engagement Elements for Compressible Caps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing capping machines for compressible material caps face significant downtime due to the complex and time-consuming process of disassembling and reassembling bottle centering devices, which requires special tools and multiple operations, especially in multiple capping machines.
Innovation Solution
The capping machine incorporates movable engagement elements that allow bottle centering devices to be assembled and disassembled without removing screw or bolt fastening elements, enabling manual operation without tools, and includes a safety locking device for secure positioning, reducing downtime and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw or bolt fastening means are used to connect the support structure to the compression box, then the connection is secure and reliable, but the disassembly and assembly process becomes time-consuming and requires special tools
Solution Approach 1:
The patent applies the dynamics principle by making the engagement elements movable rather than fixed. The engagement elements can dynamically transition between an engaged state (protruding to lock the support structure) and a disengaged state (retracted to allow removal). This dynamic characteristic enables quick tool-free disassembly while maintaining secure connection during operation, resolving the contradiction between connection reliability and assembly time.
2Strength
If multiple fastening elements are used to secure the bottle centering device, then the mechanical strength of connection is improved, but the complexity of the fastening system increases
Solution Approach 1:
The patent merges multiple fastening functions into a single integrated mechanism. The movable engagement elements are combined with the compression box structure, forming an integrated fastening system that provides both security and simplicity. This merging reduces the number of separate components and operations needed, maintaining mechanical strength while reducing fastening system complexity.
Solution Approach 2:
The engagement elements are designed to be self-actuating through manual movement, eliminating the need for external tools or complex actuation mechanisms. The operator can directly move the engagement elements between engaged and disengaged states, making the fastening system self-service and reducing overall complexity while maintaining connection strength.
3Adaptability or versatility
If the bottle centering device is designed for removable connection, then adaptability for different bottle formats is improved, but the frequency of disassembly and reassembly operations increases
Solution Approach 1:
The dynamic movable engagement elements enable rapid transition between connected and disconnected states, making the removable connection practical for frequent format changes. The quick-engagement mechanism ensures that even with increased disassembly frequency, the actual time lost is minimal, maintaining productivity while achieving high adaptability to different bottle formats.

AI summary
A capping machine for caps made of compressible material includes a compression box and compression units, each being housed in a cavity in the compression box and defining a cap compression seat. A bottle centering device is associated with each compression unit and is mechanically associated with the compression box at a housing seat on a lower face. The capping machine includes a fastener for removably retaining each bottle centering device in its respective housing seat. The fastener includes for each bottle centering device a movable engagement element movably associated with the lower face moveable between: a locking position, wherein the movable engagement element interferes with the respective bottle centering device creating an undercut to retain the bottle centering device inside the housing seat; and an unlocking position, wherein the movable engagement element does not interfere, allowing the bottle centering device to freely engage or disengage the housing seat.
