Solution Overview

Problem

Existing feed or storage containers for container closures are inefficient in changing types of closures quickly, often requiring extensive downtime and manual intervention, especially when switching between small and large batches, leading to potential errors and increased personnel requirements.

Innovation Solution

A device with multiple chambers, each with a movable blocking mechanism and an angled chamber wall to prevent slipping, allowing for simultaneous storage and easy switching between types of container closures, with optional pneumatic or manual actuation for efficient filling and emptying, and a closable opening for hygienic and efficient emptying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a single large storage container is used to minimize refilling for large batches, then the storage volume is maximized, but the time required to change closure types increases significantly

Engineering Contradiction:
Improvestorage volumeVSAvoidchangeover time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The storage container is divided into multiple separate chambers (first chamber, second chamber, etc.), each capable of storing different closure types independently. This segmentation allows operators to quickly switch between closure types by activating different chambers without emptying the entire storage system, thus reducing changeover time while maintaining adequate storage capacity for each closure type.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates movable locking means that can dynamically block or release the path from different chambers to the outlet opening. This dynamic control mechanism enables rapid switching between different closure types by simply moving the locking means, rather than physically reconfiguring or emptying the entire storage container, thereby minimizing changeover time.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If manual emptying of the storage container is required when changing closure types, then the device complexity is minimized, but the personnel requirements and potential for errors increase

Engineering Contradiction:
Improvedevice complexityVSAvoidease of operation
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The system employs automatic locking and release mechanisms that control the flow of closures from different chambers without requiring manual intervention. The movable locking means automatically block or release paths based on operational requirements, reducing the need for personnel to manually empty or reconfigure the storage system, thereby improving ease of operation while maintaining manageable device complexity.

Inventive Principle:
Principle #25Self-service

3Loss of time

If the storage container is located along the conveyor line for quick access, then the changeover speed is improved, but the available space is limited and the system becomes more complex

Engineering Contradiction:
Improvechangeover timeVSAvoiddevice complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The storage system is segmented into multiple independent chambers with individual outlet openings, each capable of feeding closures to the conveyor line. This segmentation allows the system to maintain a compact footprint along the conveyor line while providing multiple closure type options, reducing changeover time without requiring excessive space or complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The storage device is designed with multiple chambers that can store different closure types simultaneously, making the single device capable of handling multiple closure types without requiring separate storage locations along the conveyor line. This multi-functionality reduces both space requirements and device complexity while maintaining quick changeover capability.

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

AI summary

A device for feeding small parts, such as container closures (18), onto a conveying device (7) is shown. The device comprises at least one outlet opening (3) for container closures and a first chamber (1) with a filling opening (4) for container closures and with at least one chamber wall (6) arranged at an angle in the operating state of the device, which allows container closures to slide towards the outlet opening (3). The device is characterized in that at least one second chamber (2) is provided, which can be filled via a second filling opening (5). The first and second chambers have movable locking means (10) to selectively open or close the path for container closures to the common outlet opening (3).
