Conveyor dishwasher and method for operating a conveyor dishwasher
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor dishwashers, especially rack conveyor dishwashers, face inefficiencies in operation due to irregular loading when staffed by a single person, leading to wasted space and reduced dishwashing capacity, as they cannot be optimally utilized without sufficient personnel to manage continuous loading and unloading efficiently.
Innovation Solution
A detection system and control device are implemented to activate and deactivate the conveyor apparatus based on the presence of washware at the inlet and outlet, allowing for efficient operation by one or multiple staff members by ensuring washware is only processed when present, thereby optimizing machine utilization and reducing unnecessary movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conveyor dishwashers are operated with single staff member, then labor cost is reduced, but machine utilization efficiency deteriorates due to irregular loading and gaps in processing
Solution Approach 1:
The conveyor dishwasher system performs self-monitoring and self-regulation through detection systems that automatically detect washware presence at inlet and outlet, and the control device automatically adjusts conveyor operation without requiring manual intervention from staff members
Solution Approach 2:
The system implements feedback control by using detection systems to monitor washware presence and conveying position, then feeding this information back to the control device which adjusts conveyor activation accordingly, ensuring continuous processing without gaps
2Productivity
If conveyor apparatus operates continuously, then processing capacity is maximized, but energy consumption increases due to unnecessary operation when no washware is present
Solution Approach 1:
The conveyor apparatus operates periodically rather than continuously, being activated only during periods when washware is detected at the inlet and deactivated when no washware is present or when all washware has been conveyed to the outlet
Solution Approach 2:
The control device receives feedback from detection systems about washware presence and conveying status, then adjusts conveyor operation accordingly to activate only when needed and deactivate when unnecessary, optimizing energy usage

AI summary
A flight-type dishwasher or rack conveyor dishwasher has a conveyor apparatus (20) for conveying washware through individual treatment zones (11, 12, 13, 14, 15) of the conveyor dishwasher (1). The conveyor dishwasher (1) has a detection system (30) designed to detect the presence of washware or a washware carrier (7) in a predefined region (A) at an inlet (10) or at a feed (16) of the conveyor dishwasher (1). A control device (50) is designed to actuate the conveyor apparatus (20) such that the conveyor apparatus (20) is activated when washware or a washware carrier (7) is detected in the region (A) at the inlet (10) or feed (16) of the conveyor dishwasher (1), and that the conveyor apparatus (20) is deactivated when no washware or no washware carrier (7) is detected in the region (A) at the inlet (10) or feed (16) of the conveyor dishwasher (1).
