Valve Applicator Unit with Angled Shafts for Packaging Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure relief valve applicator systems for packaging, such as coffee, face challenges with misalignment of valves due to variables and tolerances in packaging processes, leading to inaccurate placement over the packaging openings.
Innovation Solution
A valve applicator unit with a punch shaft and an applicator shaft, mounted on a plate that allows for rotational movement, ensuring the punch and applicator vacuum head are angled and pivotally positioned to accurately align and apply pressure relief valves in operating register with packaging openings, using a system with a base unit, guide rollers, electronic, and pneumatic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pressure relief valves are applied using conventional applicator systems, then the packaging process can be completed, but misalignment between the valve and packaging opening occurs due to variables and tolerances in forming and filling processes
Solution Approach 1:
The applicator unit employs dynamic adjustment mechanisms including a movable applicator head that can shift position along the packaging web, and an adjustable punch mechanism that can be repositioned relative to the packaging opening. This dynamic capability allows the system to compensate for variations in packaging dimensions and valve positions, maintaining accurate alignment despite tolerances in the forming and filling processes.
Solution Approach 2:
The system incorporates sensors and control mechanisms that detect the position of the packaging opening and the valve on the web. This feedback information is used to automatically adjust the applicator head and punch positions, ensuring precise alignment between the valve and opening. The feedback loop continuously monitors and corrects positioning errors throughout the packaging process.
2Device complexity
If the applicator unit uses fixed positioning for punch and vacuum head, then the device structure is simple, but misalignment occurs due to packaging process variables
Solution Approach 1:
The applicator unit employs dynamic adjustment mechanisms including a movable applicator head that can shift position along the packaging web, and an adjustable punch mechanism that can be repositioned relative to the packaging opening. This dynamic capability allows the system to compensate for variations in packaging dimensions and valve positions, maintaining accurate alignment despite tolerances in the forming and filling processes.
Solution Approach 2:
The applicator unit is divided into functionally independent segments: a punch mechanism for creating the opening, a separate applicator head for valve application, and a vacuum system for holding the valve. Each segment can be independently adjusted and positioned, allowing precise control over the relative positions of these components while maintaining overall structural organization.
3Productivity
If pressure relief valves are applied continuously during packaging, then productivity is improved, but alignment accuracy decreases due to process variables and tolerances
Solution Approach 1:
The applicator unit is designed to operate continuously during the packaging process, with the applicator head moving along the packaging web to apply valves at multiple positions. The punch mechanism operates continuously to create openings as the web moves through the applicator. This continuous operation maintains high productivity while the dynamic positioning capabilities ensure continuous accurate alignment.
Solution Approach 2:
The applicator unit employs dynamic adjustment mechanisms including a movable applicator head that can shift position along the packaging web, and an adjustable punch mechanism that can be repositioned relative to the packaging opening. This dynamic capability allows the system to compensate for variations in packaging dimensions and valve positions, maintaining accurate alignment despite tolerances in the forming and filling processes.

AI summary
A method for applying pressure relief valves to packaging during the packaging process. A punch shaft and an applicator shaft each have an axis and opposed ends. The punch shaft has a punch at one end. The applicator shaft has an applicator vacuum head at one end. Each shaft moves axially between retracted and extended positions. The shafts are angled, with the punch and applicator ends more apart than the respective opposed ends, and are carried on a plate for limited rotational movement relative to the applicator unit. First the punch is pivoted from a first position into a third position, while the applicator head is simultaneously pivoted from a second position into the first position. Then the punch is pivoted from the third position back into the first position, and the applicator head is simultaneously pivoted from the first position back into the second position.
