Medication Auditing Buffer Unit for Speed Mismatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dose-packaging and auditing machines face challenges in managing differences in processing speeds, leading to potential damage and inefficiencies in packaging sachet handling.
Innovation Solution
A medication auditing support system is introduced, featuring a buffer unit within the conveying machine that temporarily stores packaging sachets to adjust the processing speed difference between the dose-packaging and auditing machines, utilizing a turret mechanism with rotating shafts to wind and feed sachets at suitable speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conveyance speed of the conveying unit and discharge speed of the discharging unit are associated, then the processing efficiency is improved, but the difference in speed cannot be absorbed when the difference is large
Solution Approach 1:
The buffer unit temporarily stores packaging sachets in advance before they reach the auditing machine, allowing the system to prepare for speed variations. This preliminary storage action enables the conveying machine to feed sachets to the auditing machine at a controlled pace that matches its processing speed, even when the dose-packaging machine operates at a higher speed.
Solution Approach 2:
The buffer unit acts as an intermediary between the dose-packaging machine and the auditing machine, decoupling their speed relationships. This intermediate storage mechanism absorbs the speed difference by holding excess sachets temporarily, allowing the two machines to operate at different speeds without causing damage or inefficiency.
2Productivity
If the processing speed of the dose-packaging machine is increased, then the productivity is improved, but the packaging sachets may be damaged due to speed difference
Solution Approach 1:
The buffer unit provides beforehand cushioning for the packaging sachets by temporarily storing them under controlled conditions. This cushioning mechanism prevents damage that would occur from abrupt speed changes or tension forces when the dose-packaging machine operates faster than the auditing machine can process sachets.
3Productivity
If the processing speed of the auditing machine is increased, then the overall system productivity is improved, but the speed synchronization becomes more difficult
Solution Approach 1:
The buffer unit extracts the speed synchronization problem from the direct interaction between the two machines. By removing the requirement for tight speed matching through intermediate storage, the system allows each machine to operate independently at its optimal speed without complex synchronization mechanisms.

AI summary
There is provided a medication auditing support system capable of adjusting a difference between processing speeds of a dose-packaging machine and an auditing machine. A medication auditing support system 10 is provided with: a dose-packaging machine 100 configured to package medication based on prescription data and discharge continuous packaging sachets; a conveying machine 200 configured to receive the continuous packaging sachets 118 discharged from the dose-packaging machine 100 and feed the continuous packaging sachets 118; an auditing machine 300 configured to receive the continuous packaging sachets 118 fed from the conveying machine 200 and audit the medication packaged in the packaging sachets 118 based on the prescription data; and a controlling machine configured to control the dose-packaging machine 100, the conveying machine 200 and the auditing machine 300. The conveying machine 200 is provided with a turret mechanism 208 as a buffer unit.
