Solution Overview

Problem

Conventional fully automated capping machines are costly and inefficient, requiring multiple stations and operator intervention, which limits productivity in the capping process.

Innovation Solution

A dispensing apparatus with a holding portion, retaining device, and positioning device that allows for the seamless dispensing and capping of caps onto containers in a single integrated mechanism, reducing the need for multiple stations and operator intervention by using expandable gaps and jaws to manage cap placement and rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If multiple stations are used for automated capping, then automation extent is improved, but device complexity and cost increase

Engineering Contradiction:
Improveautomation of capping processVSAvoidnumber of stations
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent combines multiple capping operations (screwing, clamping, and positioning) into a single integrated station. The capping head assembly includes both screwing mechanism and clamping jaws that work simultaneously on the container, eliminating the need for separate stations and reducing overall system complexity while maintaining full automation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The capping head assembly performs multiple functions simultaneously - it screws the cap onto the container while also clamping the container body to prevent rotation. This multi-functional design consolidates what would traditionally require separate stations into one universal capping unit.

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

2Device complexity

If operator intervention is used for cap placement, then device complexity is reduced, but productivity decreases

Engineering Contradiction:
Improvesimplicity of equipmentVSAvoidcapping speed
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The container is clamped and secured in the capping head assembly before the screwing operation begins. This preliminary clamping action prevents container rotation during cap application, enabling automated high-speed operation without requiring manual intervention to stabilize the container.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The clamping jaws act as an intermediary mechanism between the automated screwing system and the container. By securing the container through clamping, the system enables automated operation without direct operator handling, thus maintaining productivity while reducing device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If conventional transporting systems are used between stations, then ease of operation is improved, but loss of time increases due to multiple transfer points

Engineering Contradiction:
Improvecontainer transportVSAvoidtime for station transfers
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

By consolidating all capping operations into a single station, the patent eliminates multiple transfer points between stations. The container remains in the same capping head assembly throughout the entire capping process, removing the time losses associated with transporting containers between multiple separate stations.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present invention provides a dispensing apparatus adapted to dispense a cap for capping a container from a plurality of caps. Dispensing apparatus includes a holding portion for holding the plurality of caps; a retaining device including a gap, the gap expandable between a retaining configuration such that the plurality of caps is prevented from passing through the gap thereby retaining the plurality of caps within the holding portion and a releasing configuration wherein the cap is releasable from the holding portion through said gap; a positioning device configured to receive the cap from the retaining device, the positioning device includes an opening, the opening is expandable between a narrow configuration such that the cap is not passable therethrough and a wide configuration such that the cap is passable therethrough. The gap of the retaining device is expandable to the releasing configuration to release the cap therethrough when the opening of the positioning device is retracted to the narrow configuration to retain the cap within the positioning device when the positioning device receives the released cap, and the gap of the retaining device is retractable to the retaining configuration to retain the plurality of caps within the holding portion when the opening of the positioning device is expanded to the wide configuration to release and dispense the cap. Further, a capping apparatus having the dispensing apparatus is adapted to cap a container with a cap. A method of dispensing a cap for capping a container from a plurality of caps is provided. A method of capping a container with a cap is provided.
