Automated Paint Bucket Cleaning Device with Scraper and Flushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual handling of large paint buckets for cleaning is labor-intensive, risky, and often violates safety regulations due to the weight and size of the buckets and paint residues, leading to potential equipment damage and accidents.
Innovation Solution
An automated device that includes a system for lifting, tilting, and cleaning paint buckets using a combination of lifting columns, grippers, scraper, and flushing means, with a central control unit for coordinated operation, allowing for efficient and safe removal of paint residues without manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual handling of large paint buckets is used for cleaning, then the cleaning process can be performed, but the physical strain on workers increases and safety risks arise due to the weight and size of the buckets and paint residues
Solution Approach 1:
The cleaning device performs the cleaning operation autonomously without requiring manual handling of the buckets. The automated system includes lifting mechanisms, positioning devices, and cleaning components that work together to clean buckets automatically, eliminating the need for workers to manually lift and handle the heavy buckets and paint residues
Solution Approach 2:
The patent replaces manual mechanical handling with an automated mechanical system. The device uses lifting columns, grippers, and positioning mechanisms to automatically lift, position, and clean the buckets, substituting human manual operations with automated mechanical processes that are safer and more efficient
2Reliability
If manual handling of paint buckets is used, then the cleaning process can be completed, but the risk of equipment damage and accidents increases
Solution Approach 1:
The device cleans buckets autonomously through a coordinated sequence of automated operations including lifting, positioning, scraping, and flushing. This self-service capability eliminates the need for manual intervention throughout the cleaning process, thereby reducing safety risks while maintaining efficient cleaning performance
Solution Approach 2:
The cleaning process is divided into distinct sequential operations: lifting the bucket, positioning it upside down, scraping the interior surface, and flushing with water. Each operation is performed by specialized components in a controlled sequence, ensuring safe and efficient cleaning without manual handling
3Weight of moving object
If two members of staff work together to handle heavy buckets, then the buckets can be lifted and turned over, but the labor intensity increases and working conditions become more complex
Solution Approach 1:
The automated lifting and positioning system handles the heavy buckets independently without requiring multiple workers. The lifting columns and grippers are designed to securely hold and position the buckets upside down, eliminating the need for coordinated manual handling by multiple staff members
Solution Approach 2:
The device employs dynamic positioning mechanisms that can adapt to the bucket's weight and position. The lifting columns and grippers provide controlled, adjustable forces to safely handle the varying weight of buckets and paint residues, replacing the need for multiple workers coordinating their efforts

AI summary
The invention relates to the automated cleaning of paint buckets (2). In a device intended for this purpose the curled mouth rims (6) of the buckets are pushed slidingly one by one into the teeth (22,23) of a lifting fork (21), tilted and positioned in upside down position at the location of a scraping station (12), where paint residues are removed from the inner surface by scraping. A thus cleaned bucket is then transported in upside down position to a flushing station (17) where the last paint residues are removed by flushing and spraying clean. The thus cleaned buckets are finally tilted back to their upright position and stacked onto each other in nested form.
