Solution Overview

Problem

Existing plate element processing machines require manual intervention or continuous inspection to divert and eject non-compliant plate elements, which disrupts the processing flow and slows down the machine.

Innovation Solution

A switching device with a tilting transport mechanism, utilizing a vacuum belt and pivot system, allows for continuous plate element advancement without slowing down the machine, enabling on-demand or programmed diversion to different downstream modules without contact with the upper face of the plate elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual intervention or continuous inspection is used to divert non-compliant plate elements, then the quality control is improved, but the processing speed decreases and the machine must slow down

Engineering Contradiction:

Solution Approach 1:

The vacuum switching device is pre-positioned and activated only when non-compliant plate elements are detected, allowing quality control measures to be taken without disrupting the continuous flow and processing speed of compliant elements

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The non-compliant plate elements are extracted and diverted from the main processing circuit using the vacuum switching device, allowing them to be removed on-demand without slowing down the continuous processing of compliant elements

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If the machine stops to manually remove non-compliant plate elements, then the quality control is improved, but the productivity decreases due to interruptions

Engineering Contradiction:

Solution Approach 1:

The vacuum switching device automatically diverts non-compliant plate elements without requiring manual intervention or machine stopping, enabling the system to self-regulate quality issues while maintaining continuous processing

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The vacuum switching device is ready and positioned to immediately divert non-compliant elements upon detection, eliminating the need to stop the machine and maintaining uninterrupted processing flow

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If contact-based ejection methods are used to remove non-compliant plate elements, then the diversion capability is improved, but the printed surface integrity deteriorates

Engineering Contradiction:

AI summary

A switching device (130) for transferring and ejecting a plate-shaped element (20) in a sorting unit (100) comprises: – transport means (132) that are able to move (A) the plate-shaped element (20) from upstream to downstream; – a pivot (134) positioned at the level of an upstream portion of the transport means (132) and allowing the transport means (132) to pivot about a horizontal transverse axis (R2); and – lifting means (135) that are secured at the level of a downstream portion of the transport means (132) so as to make the downstream portion of the transport means (132) pivot between an upper first position and a lower second position and vice versa, so as to switch the plate-shaped element (20) respectively upward and downward.
