Solution Overview
Problem
Existing tablet supply apparatuses face challenges in accurately controlling the rotation speed and interval of tablet supply to a rotary plate for inspection, particularly when dealing with varying tablet shapes and inspection difficulties.
Innovation Solution
A tablet supply apparatus that utilizes centrifugal force to position tablets on a rotary plate with an inclined surface, combined with a guide unit and cover system to ensure consistent and efficient transfer to an inspection unit, including features like an uneven pattern on the transfer plate for increased friction and an inversion prevention unit to prevent tablet inversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a holding groove or accommodation groove is formed around a transfer drum to hold tablets at predetermined intervals, then tablets can be supplied to the inspection unit, but it becomes difficult to accurately control the rotation speed of the transfer drum and the speed and interval of the supply unit
Solution Approach 1:
The patent replaces the mechanical groove-based tablet holding system with a centrifugal force-based system. Tablets are supplied onto a rotating plate that utilizes centrifugal force to naturally position and eject tablets at appropriate intervals, eliminating the need for complex mechanical groove structures and precise speed control mechanisms.
Solution Approach 2:
The rotating plate system is self-regulating through centrifugal force. As the plate rotates, tablets naturally move outward due to centrifugal force and are ejected when they reach the appropriate position, without requiring external control mechanisms for timing or positioning. The system uses the physical properties of the tablets and the rotation itself to achieve proper spacing.
2Manufacturing precision
If the transfer drum rotation speed and supply unit speed are precisely controlled to match predetermined intervals, then accurate tablet positioning is achieved, but the system becomes complex and难以 to vary inspection speed according to tablet shapes or inspection difficulties
Solution Approach 1:
The patent enables easy variation of inspection speed by changing the rotation speed parameter of the rotating plate. Since the system relies on centrifugal force rather than fixed mechanical intervals, the rotation speed can be adjusted according to different tablet shapes and inspection requirements without affecting the fundamental operation or positioning accuracy of the system.
3Device complexity
If centrifugal force is used to supply tablets to the rotary plate without considering supply speed and interval, then the control and structure are simplified, but additional mechanisms are needed to ensure consistent transfer
Solution Approach 1:
The guide unit is positioned and configured in advance to receive tablets from the rotating plate at the correct location and orientation. The guide unit's structure, including its inclined surface and positioning features, is designed beforehand to ensure tablets are correctly oriented and transferred to the inspection unit without requiring active control during operation.
Solution Approach 2:
The guide unit acts as an intermediary between the rotating plate and the inspection unit. It receives tablets ejected by centrifugal force from the rotating plate and mediates their transfer to the inspection unit, ensuring proper positioning and orientation. This intermediary structure ensures reliable transfer without requiring complex control mechanisms.

AI summary
A tablet supply apparatus includes: a base frame; a rotary plate rotatably installed on the base frame to outwardly position a tablet by centrifugal force, and inclinedly positioned to have a top dead center point and a bottom dead center point; a transfer plate positioned to surround the rotary plate, rotated with the rotary plate, and having an inclined surface outwardly and downwardly inclined on the same level as that of the top dead center point of the rotary plate, in order to receive the tablet from the top dead center point of the rotary plate; and a guide unit disposed on the outer peripheral surface of the transfer plate, the guide unit allowing the tablet, positioned and transferred on the inclined surface of the transfer plate, to be discharged toward the rotary plate of the inspection unit by centrifugal force and a sliding movement.
