Rotational counting and bottling machines can handle irregularly shaped tablets, such as ovals and irregular shapes, but this requires the following special design:
1.Customized Counting Template
Design Principle: Traditional counting template has regular round holes and is suitable for standard tablets only. For irregularly shaped tablets, you'll need to customise holes (such as ellipses, polygons or irregular silhouettes) to match the shape of the tablet to ensure each hole can only hold one tablet.
Application example: a device model of automatic counting and filling of irregular shaped tablets and capsules by a unique design counting board is compatible with standard tablets and capsules, which greatly improves the equipment's adaptability.
2.Optimization Vibrating Feeder
Electromagnetic vibration of three-stage vibration plate: using adjustable frequency vibration mechanism, the flow rate of tablet is controlled in stages by primary, intermediate and last stage vibration feeder. High-speed vibrations ensure rapid separation of tablets, while a three-step design allows tablets to slide layer by layer, increasing spacing and preventing overlap.
Performance Verification: This design improves the drop distance of irregularly shaped tablets by 30%, reduces overlap rate from 5% to below 0.2%, and improved counting accuracy to 99.8%.
3.Anti-interference Photoelectric Sensing Technology
Technical Principle: Traditional photoelectric sensors are prone to miscalculation in a plane environment with high dust or irregular shape. The device employs anti-dust photoelectric sensing technology to optimize light source wavelength (e.g., green light at 520nm) and optical path design to reduce dust scattering interference. It also combines dynamic scanning algorithm to determine each tablet's unique contour signals.
Data support: The device was still able to consistently identify irregularly shaped tablets at dust concentrations of up to 10mg/m3, with a count error rate of less than 0.1%.
4.Flexible Leak Structure
Purpose: For small-mouthed medicine bottles, a traditional leak can easily cause irregular shaped tablets to get stuck. The elastic leak design of elastic material or deformable structures can be automatically adapted to the drip path of different shaped tablets to prevent blockage.
How it works: With a dedicated nozzle on the device, the filling speed of the sip bottle increases by 40% and the clogging rate drops from 15% to below 0.5%.
V. Intelligent Parameter Adjustment System.
Function Implementation: The device integrates an intelligent control system that automatically recognizes the shape and size of the drug and adjusts parameters (such as vibration frequency, track spacing, nozzle opening andclosing and closing). Operators only need to enter the drug type, and the system can complete the parameter match.
For example, models that support storage of 10 sets of parameters can be recalled directly upon replacement, reducing changeover time from 2 hours to 10 minutes.
6.Machine Vision Assisted Counting (optional)
Upgrade: Some high-end devices introduce artificial intelligence visual recognition technology that captures images of drugs through cameras, uses deep learning algorithms to identify shapes, colors and defects, further eliminates nonconforming products and optimizes counting logic.
Efficiency Improvement: With the vision system, the device can count 4000 irregularly shaped pills aminute, 3 times faster than conventional devices, while keeping detection rate below 0.05%.
