Internal Substance Supplier for Compression Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rotary compression-molding machines face challenges in accurately and reliably supplying internal substances, such as IC chips, into the die bores for incorporation into molded products, particularly in pharmaceutical applications, where the substances need to be buried within the product.
Innovation Solution
A supplier system comprising a conveying mechanism with rotatable members and a supply mechanism that includes a scraping member, gliding member, and push transfer member to guide and transfer the internal substance into the die bore, ensuring precise placement without the need for four or more rotators, and includes features like suction units and static elimination to manage electrostatic charges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional conveying system is used to supply internal substances, then the structure becomes complex requiring four or more rotators, but the supply reliability is insufficient
Solution Approach 1:
The patent combines multiple functions into a single integrated conveying system with three rotators. The first rotator conveys internal substances from the storage chamber, the second rotator transfers them to positioning positions, and the third rotator positions them above die bores. This merged configuration achieves reliable supply while reducing the number of rotators to minimally necessary three, eliminating the need for four or more separate rotating components.
2Reliability
If the internal substance is electrostatically charged, then the substance may adhere to conveying surfaces, but the patent provides solutions through static elimination features
Solution Approach 1:
The patent converts the harmful electrostatic charge into a beneficial effect by using electrostatic attraction. The conveying surfaces are designed with electrostatic charge that attracts and holds the internal substances during conveying, then releases them at designated positions. This is supplemented by static elimination features to prevent unwanted adhesion, transforming the electrostatic property from harmful to useful.
3Manufacturing precision
If precise placement of internal substances is required in die bores, then the positioning mechanism becomes complex, but the patent achieves precision with simplified mechanisms
Solution Approach 1:
The patent segments the positioning function across three distinct rotators, each handling a specific stage of positioning. The first rotator handles rough conveying, the second rotator performs intermediate transfer to positioning positions, and the third rotator executes final precise positioning above die bores. This segmentation achieves high placement precision while keeping each rotator's mechanism simple and manageable.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables reliable and precise delivery of internal substances into the die bore, ensuring they are accurately incorporated into the molded product, even when the substances are electrostatically charged, with a minimally necessary configuration of three rotatable components.
Implementation Method 1
a suction unit configured to suck to retain the internal substance until the internal substance colliding with the scraping member is pushed to the start edge of the recessed groove in the gliding member
Implementation Method 2
an outlet opening positioned to confront the internal substance pushed to the start edge of the recessed groove in the gliding member and allowing air for static elimination of the internal substance to blow out

AI summary
An internal substance supplier includes a conveying mechanism including a conveying member configured to capture and convey an internal substance, and a supply mechanism including a scraping member disposed to cross a conveyance route of the substance by the conveying member in the conveying mechanism and configured to collide with the substance conveyed by the conveying member, a gliding member including a recessed groove configured to guide the substance colliding with the scraping member and scraped from the conveying member, to be adjacent to a position vertically above a die bore in a table in a compression-molding machine, and a push transfer member including a projection configured to come into contact with the substance, push the substance to a start edge of the recessed groove in the gliding member, and move along the recessed groove to transfer the substance to an end edge of the recessed groove.
