Problem

Current automated conveying systems lack direct and accurate object delivery to washing apparatuses, requiring manual intervention, leading to increased operator workload and reduced efficiency.

Innovation Solution

A conveying/loading apparatus comprising a first and second delivery part with a blocking apparatus and control system, utilizing detection sensors and a variable-frequency controller to automate the loading process, ensuring precise positioning and speed adjustment for efficient object transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual intervention is used to transfer objects from conveying apparatus to washing apparatus, then flexibility and adaptability are maintained, but operator workload increases and working efficiency decreases

Engineering Contradiction:
Improvewashing efficiencyVSAvoidoperator workload
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system enables self-service automated loading where the conveying apparatus automatically positions and loads objects onto the washing apparatus without manual intervention. The control system coordinates the conveying apparatus and washing apparatus to achieve automatic object transfer, eliminating the need for operators to manually handle objects while maintaining continuous operation capability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The conveying apparatus serves as an intermediary between the object source and washing apparatus. It automatically transports objects and positions them at the washing position through coordinated control, acting as a mediator that eliminates direct manual handling while ensuring precise object delivery to the washing apparatus

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If automated conveying is implemented without precise positioning capability, then automation level increases, but object delivery accuracy to washing position deteriorates

Engineering Contradiction:
Improveautomation levelVSAvoidobject delivery accuracy
Core Design Contradiction:
Extent of automationVSMeasurement precision

Solution Approach 1:

The control system implements feedback control by monitoring the position of objects on the conveying apparatus and adjusting the conveying speed and positioning accordingly. This ensures that objects are delivered accurately to the washing position while maintaining automated operation, resolving the contradiction between automation level and delivery precision

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The conveying apparatus uses dynamic speed adjustment and positioning control to achieve precise object delivery. The system can dynamically modify conveying parameters based on real-time position information, enabling accurate object placement at the washing position while maintaining high automation level

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If blocking apparatus is added to control object passage, then automated loading precision improves, but device complexity increases

Engineering Contradiction:
Improveloading precisionVSAvoidapparatus structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The blocking function is extracted as a separate, simple apparatus component that can be independently controlled. This modular approach allows the blocking apparatus to be added to control object passage without significantly increasing overall system complexity, while still achieving improved loading precision through coordinated control with the main control system

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A conveying/loading apparatus includes a first conveying apparatus having a first delivery part, with a blocking apparatus being disposed close to an output end of the first delivery part, and a second conveying apparatus having a second delivery part, with multiple supports being disposed at intervals on the second delivery part, and regions between the supports forming accommodating spaces for loading objects. An object is delivered to the output end of the first delivery part, and a first detection sensor detects a position of the object. A second detection sensor detects whether a support of the second delivery part has moved to a loading position, and whether the accommodating space between two adjacent supports is in an idle state. The first detection sensor causes the blocked object to pass, when the first detection sensor and the second detection sensor both have signals.
