Solution Overview

Problem

Current container recycling systems are unable to efficiently automate the removal of metering valves from bottles with external coupling collars, requiring manual intervention and additional cutting tools, and are not adaptable to bottles with internal metering valves.

Innovation Solution

An automated extractor machine with a gripper mechanism and rotary carousel design that can remove metering valves from containers with both external and internal configurations, using jaws that move between closed and open configurations to engage and extract the valve, allowing for efficient and versatile operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual removal method is used, then metering valve can be removed from bottles, but production time increases and manpower requirement increases

Engineering Contradiction:
Improveautomation of metering valve removalVSAvoidproduction time
Core Design Contradiction:
Extent of automationVSProductivity

Solution Approach 1:

The extraction head uses a self-actuating mechanism where the gripper jaws automatically open upon engaging the metering valve, allowing the valve to be pulled out without manual intervention. The system performs the removal operation autonomously through coordinated mechanical movements of the gripper and extraction head.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual knife-based mechanical removal system with an automated gripper-based extraction mechanism. The gripper uses clamping force and pulling motion to remove the metering valve, substituting the cutting and breaking operations with a simpler mechanical extraction process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple cutting tools are used for different bottle types, then various metering valve configurations can be handled, but device complexity increases

Engineering Contradiction:
Improveadaptability to different bottle typesVSAvoidnumber of cutting tools
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gripper mechanism is designed with universal applicability to handle both external coupling collars and internal metering valves. The same gripper structure can adapt to different valve configurations by adjusting its closing position and engagement method, eliminating the need for multiple specialized cutting tools.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The extraction head and gripper are designed with movable and adjustable components that can dynamically adapt to different bottle and valve configurations. The gripper jaws can adjust their closing position and engagement depth to accommodate various metering valve types, providing versatility without requiring multiple fixed tools.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If extractor machine is designed for external coupling collars, then those specific valves can be removed, but internal metering valves cannot be handled

Engineering Contradiction:
Improvehandling of internal and external valve configurationsVSAvoidgripper mechanism design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gripper is designed with segmented jaws that can independently position and engage different parts of the metering valve assembly. The jaws can separately target the external coupling collar or the internal valve body, allowing the same mechanism to handle both configurations through selective engagement of different structural elements.

Inventive Principle:
Principle #1Segmentation
