Solution Overview

Problem

Existing feed devices struggle with unstable stacks of container components, such as snap-on lids, which can lead to interruptions in the filling process due to their susceptibility to forces acting transversely to the stacking direction, particularly affecting systems that require continuous operation.

Innovation Solution

A feed device with stabilizing devices arranged at an angle to each other, allowing for a space-saving and improved operability, where the receiving shafts can be moved individually or in groups to maintain a stable stacking position, and the buffer magazine is designed with a pull-out window for easy access and protection against intrusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If stacks of snap-on lids are fed into receiving shafts for stabilization, then the stability of the stacks is improved, but the device complexity increases due to the need for stabilizing devices with receiving shafts arranged in specific directions

Engineering Contradiction:
Improvestack stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The receiving shafts are arranged in a direction that is not parallel to the movement path, creating a spatial configuration that stabilizes stacks in multiple dimensions. This angular arrangement allows the shafts to counteract transverse forces while maintaining a compact buffer magazine structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The buffer magazine is divided into multiple receiving shafts that can be individually accessed through the pull-out window. Each receiving shaft acts as an independent stabilization unit, allowing selective refilling and maintenance without disrupting the entire system.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the buffer magazine is designed with a pull-out window for easy access, then the ease of operation is improved, but the protection against intrusion becomes more challenging

Engineering Contradiction:
Improveease of refillingVSAvoidintrusion protection
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The pull-out window serves as an intermediary access point that allows operators to refill receiving shafts without direct access to the interior of the buffer magazine. This controlled access mechanism maintains security while enabling easy operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The pull-out window extracts the refilling function from the main buffer magazine structure, allowing receiving shafts to be accessed and refilled independently through a dedicated opening that maintains the integrity of the overall system.

Inventive Principle:
Principle #2Taking out (Extraction)

3Volume of moving object

If stabilizing devices are arranged at an angle to the movement path, then the space utilization is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvespace utilizationVSAvoidangular positioning precision
Core Design Contradiction:
Volume of moving objectVSManufacturing precision

Solution Approach 1:

The angular parameter of the receiving shafts relative to the movement path is optimized to balance space utilization and manufacturing feasibility. The specific angle is chosen to provide adequate stabilization while remaining within standard manufacturing tolerances.

Inventive Principle:
Principle #35Parameter changes

AI summary

A feeding device for container parts, for use in a device for filling containers with liquid to pasty and/or free-flowing foodstuffs, comprises a stabilizing device with receiving chutes. The receiving chutes are arranged in a row in a first direction. A discharging device conveys container parts held in stacks in the receiving chutes of the stabilizing device and arranges them in a feeding frame. Several stabilizing devices together form a buffer magazine that can be filled with nestable container parts and are arranged in a row along a common path of movement in a second direction. The stabilizing devices are linearly movable along the path of movement to position at least one stabilizing device loaded with container parts within the operating range of the discharging device. The first direction is different from the second direction.
