Double Rotation Drug Feeder for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drug feeders, particularly the modified flange rotation type, face challenges with frequent cleaning requirements due to delicate components and increased complexity, leading to operational burdens and maintenance issues when handling a wide range of drug shapes and sizes.
Innovation Solution
A double rotation type drug feeder design featuring an annular first rotator and a second rotator inclined within, supported by multiple members for friction transmission, eliminating the need for a fixed flow guide and simplifying the structure for easy cleaning and maintenance, with a driving member comprising a large-diameter and small-diameter portion for efficient rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a modified flange rotation type drug feeder is used to handle a wide range of drug shapes and sizes, then the adaptability is improved, but the device complexity increases and cleaning workability deteriorates
Solution Approach 1:
The drug feeder is divided into separable components: a rotatable container that can be removed and a stationary body. This segmentation allows the container to be detached for cleaning without disassembling the entire device, reducing cleaning complexity while maintaining the ability to handle various drug shapes through the container's design
Solution Approach 2:
The rotatable container serves multiple functions: it stores drugs of various shapes and sizes, rotates to dispense them, and can be removed for cleaning. This multi-functionality reduces the need for multiple specialized components, simplifying the overall device structure while maintaining high adaptability
2Adaptability or versatility
If a modified flange rotation type drug feeder is used to handle various drug shapes, then the adaptability is improved, but the ease of operation deteriorates due to frequent cleaning requirements
Solution Approach 1:
By separating the rotatable container from the stationary body, the design enables quick removal and cleaning of only the container portion. This reduces the time and effort required for maintenance operations, making the device easier to operate despite its high adaptability to various drug shapes
3Manufacturing precision
If a fixed flow guide is used in the rotator, then the manufacturing precision is improved, but the ease of repair deteriorates
Solution Approach 1:
The flow guide function is integrated into the rotatable container rather than being a separate fixed component. This allows the entire container to be removed and cleaned as a single unit, greatly improving ease of repair and maintenance while still providing precise flow guidance through the container's shaped interior

AI summary
A double rotation type drug feeder having an easily cleanable, simple structure is provided. The drug feeder includes a rotatable annular first rotator 20 that has a mount surface 23 on which drugs are placed and that is rotatable about a first rotation axis, a second rotator 30 that is disposed at a fixed position on an inner side of the first rotator 20 while being rotatable about a second rotation axis, inclined with respect to the first rotation axis, the second rotator 30 transporting the drugs onto the mount surface 23, restricting members 71 and 72 that align the drugs disposed on the mount surface 23, and multiple support members 40 that support the first rotator 20 and the second rotator 30 mounted thereon from below the first rotator 20 and the second rotator 30. The multiple support members 40 include a driving member 55 that drives the first rotator 20 and the second rotator 30 to rotate.
