Radially Adjustable Bottle Centering for Compressible Cap Capping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capping machines for compressible caps require multiple centering cones for different bottle sizes, leading to complex and time-consuming adjustments, with a risk of errors and long downtimes.
Innovation Solution
A bottle centering device with radially movable pieces that adjust the invitation seat's dimensions, allowing adaptation to various bottle sizes without replacing the device, using an adjustment ring nut for coordinated radial movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dedicated centering cones are used for each bottle mouth size, then perfect centering is ensured, but device complexity increases and adjustment time increases
Solution Approach 1:
A single centering device incorporates multiple centering cones with different dimensions, allowing it to serve multiple functions for different bottle mouth sizes. The device can be adjusted to accommodate various bottle formats without requiring separate centering cones for each size, thus reducing overall device complexity while maintaining centering precision.
Solution Approach 2:
The centering device is divided into multiple modular centering cones that can be independently selected or adjusted. Each cone is designed for a specific bottle mouth size, and the segmentation allows the operator to choose the appropriate cone for the current production run, ensuring precise centering while avoiding the need to maintain a complete set of individual centering cones.
2Manufacturing precision
If dedicated centering cones are used for each bottle mouth size, then perfect centering is ensured, but adjustment time increases
Solution Approach 1:
The centering device incorporates quick-adjustment mechanisms that allow dynamic change between different centering cone configurations. This enables rapid adaptation to different bottle mouth sizes without the time-consuming process of complete disassembly and reassembly, significantly reducing adjustment time while maintaining the precision required for each specific bottle format.
3Adaptability or versatility
If multiple centering cones are maintained for different bottle sizes, then adaptability to various formats is achieved, but the risk of installation errors increases
Solution Approach 1:
Multiple centering cones are integrated into a single unified device structure with standardized mounting interfaces and alignment features. This merging reduces the risk of installation errors by providing a consistent, foolproof mounting procedure regardless of which centering cone is being installed, while maintaining the ability to accommodate various bottle formats through the selectable cone configurations.

AI summary
A bottle centering device for a capping machine for caps made of compressible material includes a support structure, associated with a compression box at a cap compression seat and defining an opening for passing a compressed cap and a cap insertion punch. The support structure is mountable on the compression box so that the through opening has a central axis axially centered on the cap compression seat. A bottle centerer defining an invitation seat and a central through opening is configured for engagement by a bottle mouth and is shaped to guide the mouth towards the through opening axially aligning with the central axis. The bottle centerer includes pieces angularly distributed about the central axis and each partially defining a portion of the invitation seat. The pieces are radially movable with respect to the central axis to vary radial dimensions of the invitation seat and the central through opening.
