Inclined Ring Transfer for Low-Speed Dosage Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alignment transfer devices face difficulties in reliably transferring solid dosage forms at low speeds, as reducing transfer speed to secure printing time can result in insufficient centrifugal force, making it challenging to move the dosage forms between components.
Innovation Solution
The alignment transfer device employs a configuration with inclined rotary and peripheral rings, featuring specific angles and recesses to maintain alignment and transfer, allowing for low-speed operation by using centrifugal force effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the transfer speed is reduced to secure printing time, then the printing time is increased, but the centrifugal force becomes insufficient and reliable transfer cannot be ensured
Solution Approach 1:
The invention employs curved inclined surfaces on the rotary disk and ring-shaped walls instead of flat surfaces. The bottom wall of the rotary disk has an inclined curved surface, and the peripheral walls of the rings have inclined surfaces that guide the solid dosage form. These curved surfaces work together to reliably transfer the dosage form even at low speeds by utilizing gravitational and centrifugal forces effectively.
Solution Approach 2:
The invention introduces a vertical dimension to the transfer mechanism by stacking multiple rings (first ring, second ring, third ring) at different heights. The solid dosage form moves not only radially outward but also vertically upward through the inclined surfaces of successive rings. This multi-dimensional transfer path ensures reliable progression of the dosage form from the rotary disk through multiple rings to the suction roller, maintaining transfer reliability at reduced speeds.
2Manufacturing precision
If the transfer speed is reduced to accommodate downstream processing, then the printing or inspection quality can be improved, but the centrifugal force becomes too weak to move the dosage form reliably
Solution Approach 1:
The curved inclined surfaces on the rotary disk bottom wall and ring peripheral walls create an effective force component that acts along the transfer path. The inclination angles of these curved surfaces are optimized to ensure that gravitational and centrifugal forces combine to move the solid dosage form reliably, even when rotational speed is reduced for high-quality printing.
Solution Approach 2:
The transfer process is divided into multiple segments through the use of separate rings (first, second, and third rings) with their own inclined surfaces. Each ring segment handles a portion of the transfer task, allowing the system to maintain effective force application at each stage even when overall transfer speed is reduced for improved print density.
3Reliability
If multiple rings with inclined surfaces are added to ensure low-speed transfer, then transfer reliability is improved, but device complexity increases
Solution Approach 1:
Each ring in the system serves multiple functions: it acts as a structural support element, provides an inclined transfer surface for moving the solid dosage form radially and vertically, and contributes to the overall alignment and positioning of the dosage form. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The invention combines the transfer function and the support function into a single integrated ring structure. The rings are rotatably supported on the common rotation axis while simultaneously providing the inclined surfaces needed for dosage form transfer. This merging of functions into unified components helps manage device complexity while achieving reliable low-speed transfer.
