Sprayer Pump Insertion Alignment for Bottle Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic capping machines struggle to accurately insert sprayer pumps into bottles due to the bending of the pump tube, which misses the bottle opening, leading to manual labor or expensive machinery being used, especially during small production runs.
Innovation Solution
A method and apparatus that simultaneously transport and secure containers on a conveyor, align and straighten the sprayer cap mechanisms, and use a diptube assembly to insert and secure the sprayer pumps into the bottles, ensuring accurate and efficient insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic capping machines are used to insert sprayer pumps into bottles, then productivity is improved, but manufacturing precision deteriorates due to tube bending causing misalignment with the bottle opening
Solution Approach 1:
The apparatus performs preliminary straightening of the diptube using guide surfaces and alignment mechanisms before the insertion operation. The transfer device positions the spray cap mechanism and diptube assembly in precise alignment with the bottle opening beforehand, ensuring the tube enters correctly without bending during insertion.
Solution Approach 2:
The patent introduces a specialized transfer device with diptube guide surfaces and alignment features that act as an intermediary between the spray cap mechanism and the bottle. This intermediary component ensures proper orientation and prevents tube bending during the transfer and insertion process.
2Manufacturing precision
If manual labor is used to insert sprayer pumps accurately, then manufacturing precision is maintained, but productivity decreases
Solution Approach 1:
The apparatus is designed to be self-aligning through fixed geometric relationships between components. The guide surfaces, alignment features, and transfer mechanism automatically position the diptube and spray cap without requiring manual adjustment, enabling both high precision and automated high-speed operation.
3Manufacturing precision
If expensive specialized machinery is used to prevent tube bending, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The apparatus segments the insertion process into distinct functional zones: a transfer zone with alignment features, an insertion zone with guide surfaces, and a securing zone. This segmentation allows each zone to perform its specific function with simple, dedicated components rather than requiring one complex machine to handle all aspects.
Solution Approach 2:
Instead of trying to prevent tube bending through complex active control mechanisms, the invention inverts the approach by designing passive geometric constraints that guide the tube into correct alignment. The fixed alignment features and guide surfaces naturally prevent misalignment without requiring sensors or active adjustment mechanisms.

AI summary
In some embodiments, an apparatus for insertion of uniquely shaped packaging may include the following elements, (a) a securing mechanism to hold a container along a conveyor in a predetermined location, (b) a transfer device which removes a spray cap mechanism from a second timing screw and aligns the spray cap mechanism over a container opening on the container, (c) a diptube assembly which locks a diptube hanging from the spray cap mechanism, and (d) the transfer device tightening the spray cap mechanism on the container opening after the diptube is inserted into the container opening.
