Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drug packaging apparatuses often experience dispensing errors and congestion in the supply path due to the sequential discharge of drug units from a storage tank, leading to inefficiencies and errors in supplying discrete drug forms.
Innovation Solution
A supply apparatus with an inclined pipe-shaped supply unit, elastically supported by a spring hinge and vibrated to facilitate smooth passage, combined with detection sensors to monitor and prevent errors, and a shutter to control discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drug units are sequentially discharged from storage tank through supply apparatus, then drug units can be supplied to packaging members, but drug units may congest in supply path and cause dispensing errors
Solution Approach 1:
The patent applies vibration to the supply path components (supply guide, supply roller) to prevent drug units from congesting and sticking during transport. The vibration mechanism shakes off accumulated drug units, ensuring smooth flow and accurate dispensing to packaging members.
Solution Approach 2:
The patent introduces intermediate components (supply guide, supply roller) between the storage tank and packaging members to facilitate controlled drug unit transport. These intermediaries manage the flow rhythm and prevent direct congestion by providing a buffered transfer path.
2Ease of operation
If drug units are conveyed through supply apparatus to packaging members, then packaging can be performed, but drug units may stay in supply apparatus causing supply errors
Solution Approach 1:
The patent employs sensors to detect the presence and position of drug units in the supply path. This feedback information is used to control the vibration mechanism and shutter, ensuring that drug units are supplied accurately to packaging members without congestion or errors.
Solution Approach 2:
The patent uses periodic vibration of the supply path components to maintain continuous drug unit flow. The vibration occurs at specific intervals to prevent accumulation and ensure rhythmic dispensing, coordinating with the shutter's periodic opening and closing.
3Ease of manufacture
If supply unit is fixed structure, then manufacturing is simple, but drug units may congest and cannot be continuously supplied
Solution Approach 1:
The patent transforms the fixed supply unit into a dynamic structure with vibration capabilities. The supply guide and supply roller can vibrate to prevent drug unit congestion, enabling continuous supply while maintaining relatively simple manufacturing through straightforward mechanical vibration mechanisms.

AI summary
Disclosed is a supply apparatus for drug packaging, used to supply a plurality of units of a drug to drug packaging members. The supply apparatus includes: a supply unit providing a supply path along which the units of a drug are supplied; a support unit elastically supporting the supply unit in such a manner such that the supply unit is inclined; a vibration unit vibrating the supply unit; and a detection unit detecting the units of a drug passing through the supply unit. According to this structure, it is possible to reduce drug supply errors, thereby improving drug supply efficiency.
