Rotating Distributor Disc for Tablet Blister Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distributor units for transferring tablets into blister strips are bulky, costly, limited in adaptability, and have low productivity, making them inefficient and difficult to maintain, while also lacking versatility for various product types and production rates.
Innovation Solution
A distributor unit with a belt-type feed system featuring open through seatings coordinated with tablet sizes, a support plane, and a closed-ring or rectilinear trajectory, allowing for efficient transfer and positioning of tablets into blister strips with adjustable speed and configuration for different tablet and blister strip types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional distributor units are used to transfer tablets into blister strips, then the structure is simple and easy to manufacture, but the productivity is low and the device is bulky
Solution Approach 1:
The patent employs a rotating distributor disc with multiple radial arms that can dynamically position tablets onto moving blister strips. The rotational motion and adjustable positioning mechanisms enable high-speed operation while maintaining a relatively compact structure, resolving the contradiction between productivity and device complexity
Solution Approach 2:
The distributor unit is divided into multiple independent radial arms, each capable of handling tablets individually. This segmentation allows parallel operation of multiple arms simultaneously, significantly increasing productivity while keeping each individual arm simple in structure
2Adaptability or versatility
If traditional distributor units are used, then the design is straightforward, but the adaptability to different tablet and blister strip types is limited
Solution Approach 1:
The distributor disc is designed with universal radial arms that can accommodate different tablet sizes and shapes through adjustable positioning. The same basic mechanism can handle various blister strip configurations, providing multi-functionality without requiring completely different designs for each product type
Solution Approach 2:
The system allows adjustment of key parameters such as radial arm positioning, rotation speed, and blister strip feed rate to adapt to different tablet and blister strip types. These parameter changes enable versatility while maintaining the same fundamental device structure
3Productivity
If high productivity is achieved with traditional distributor units, then the delivery rate increases, but the device becomes bulky and costly
Solution Approach 1:
The patent transitions from linear or planar tablet distribution mechanisms to a three-dimensional rotating disc configuration with radial arms. This dimensional change allows multiple tablets to be distributed simultaneously in different directions, achieving high productivity within a compact vertical footprint rather than requiring a large horizontal space

AI summary
Distributor unit for transferring tablets and putting them in order, from a loading zone to an unloading zone, and for distributing the tablets in an orderly and controlled manner in organized blisters present in a blister strip. The distributor unit comprises belt-type feed means in which a feed belt is provided, along at least part of its length, and along at least part of its width, with a plurality of open through seatings each having at different times sizes coordinated with those of the tablets to be distributed, said open through seatings having a transverse interaxis about equal to, and a longitudinal interaxis equal to or less than, that of the blisters in the blister strip.
