Integrated Hopper Layout for Single-Round Cleaning Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination weighing apparatuses face poor workability due to the time-consuming process of attaching and detaching hoppers, particularly when dealing with entangled articles like bean sprouts, as the detachable fences require multiple rounds of removal and attachment during cleaning.
Innovation Solution
A combination weighing apparatus design featuring hoppers arranged to surround radiation troughs, with specific outer wall configurations allowing for sequential removal and attachment in a single round of the apparatus periphery, utilizing inclined orientations and hanger units to facilitate easy detachment and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detachable fences are attached to hoppers to prevent articles from falling, then article containment is improved, but the number of attachment and detachment operations increases, worsening workability
Solution Approach 1:
The fence structure is merged with the hopper body to form an integrated unit. The fence is no longer a separate detachable component but is structurally combined with the hopper, eliminating the need for separate attachment and detachment operations while maintaining the article containment function.
Solution Approach 2:
The hopper assembly is designed to serve multiple functions: it contains articles through its fence structure, allows for easy removal as a complete unit for cleaning, and maintains structural integrity during operation. The integrated design makes the hopper a multi-functional component that combines containment and easy maintenance capabilities.
2Reliability
If multiple rounds of attachment and detachment are required for cleaning, then thorough cleaning is possible, but time consumption increases, worsening productivity
Solution Approach 1:
The cleaning process is segmented into two levels: the hopper can be quickly removed as a complete unit for external cleaning, and the internal components remain accessible for internal cleaning without requiring complete disassembly. This segmentation allows efficient cleaning in a single round while maintaining thoroughness.
Solution Approach 2:
The hopper is designed with pre-considered cleaning accessibility: the opening and closing gate and other internal components are positioned and structured to allow easy access during a single cleaning pass. The preliminary design ensures that all necessary cleaning points are accessible without requiring multiple rounds of attachment and detachment.
3Reliability
If hoppers are designed with complex attachment mechanisms for secure mounting, then reliability of mounting is improved, but ease of removal for cleaning deteriorates
Solution Approach 1:
The attachment mechanism uses dynamic elements such as gravity-based positioning and simple mechanical engagement that provide secure mounting during operation but allow easy removal when needed. The hopper's weight and geometric design work with the mounting structure to provide automatic secure engagement during filling and operation, while allowing straightforward removal for cleaning.
Solution Approach 2:
A simple intermediary mounting structure serves as the interface between the hopper and the supporting framework. This intermediary component provides reliable mounting through basic mechanical means while requiring minimal effort for removal, acting as a mediator that balances security and ease of operation.

AI summary
In the present invention, three hoppers having different shapes are prepared, and an outer wall of each of the hoppers is raised to form a hopper in which a conventional fence and the hopper are integrated. Both ends of a first hopper in a left-right direction along an outer wall thereof are located inside outer walls of hoppers located on both sides, respectively, and out of both ends of an outer wall of a second hopper, a right end is located inside an outer wall of a hopper adjacent on a right side, and a left end is located outside an outer wall of a hopper adjacent on a left side. Furthermore, an outer wall of a third hopper is located outside outer walls of hoppers located on both sides. This makes it possible to remove the hoppers in order while one round of an outer periphery of the hoppers is made.
