How Does A Rotary Counting Filling Machine Achieve Accurate Counting Of Tablets/capsules Through Mechanical Vibration?

Rotation counting filler are mechanically vibrated to achieve accurate tablet/capsule counting. This mainly depends on mechanical vibration and the template counting method in the counting template. Its core principles and methods of implementation are as follows:
i. The role of Mechanical Vibration.
Sieving Filling: The nose of a rotary filling machine is equipped with eccentric vibrations, which are driven by an electric motor and produce high frequency vibrations. This vibration causes the tablet/capsule to continuously sift through the holes in the counting template to ensure that each hole is fully filled and to prevent inaccurate counting due to material accumulation or gaps.
 _Preventing Overlapping: _  During vibration, tablets/capsules disperse due to inertia, reducing overlap or adhesion. Some devices,such as a three-stage oscillator called an electromagnetic oscillator, adjust the frequency of the vibrations, allowing the pills to slide down the stair track step by step, further increasing the spacing between the pills and avoiding miscalculations.
ii. Design of counting template
Hole Matching: The counting template is designed to have a certain number of holes equal to 100 holes per bottle (e.g. template thickness needs to be precisely controlled to ensure that each hole can accommodate only one tablet/capsule.
Rotational Separation: driven by eccentric vibration mechanism, multiple templates are rotated in sync with fixed ingredient plates. The tablet/capsule falls into the dispensing channel due to gravity to complete single particle separation and counting when the template Khonda dispensing plate gap occurs.
III. Key technical details
Vibration Frequency Adjustment: Equipment adjusts vibration frequency according to the characteristics of different materials:
Small particle size size/light weight: highfrequency vibration is required to prevent accumulation;
Large particle size/irregularly shaped materials: Low frequency vibration is required to avoid fragmentation.
Template and Dispensing Plate match: A small gap must be maintained between the template and dispensing board to ensure smooth dispensing;
The notch design of the dispensing plate must be precisely aligned with the template hole to avoid leakage or blockage.
Anti-jamming design: for the environment with high dust, the equipment adopts sealing structure to prevent dust from entering vibration mechanism;
Some models are equipped with an electrostatic elimination device to reduce electrostatic adsorption due to friction between tablets and templates.
IV. INTRODUCTION INTRODUCTION Typical Application Scenarios
Standard Tablets/Capsules: Round and regular-shaped tablets/capsules can be counted directly using a standard counting template; they can be filled effectively at moderate vibration frequency.
Irregularly Shaped Tablets: For elliptical and irregularly shaped tablets, counting templates need to be customized and vibration intensity and template hole shape adjusted to ensure effective single separations.
Small Neck Filling: For small neck vessels, the device has a specially constructed nozzle. Combined with the movement of the shaker, the pills fell one by one to prevent blockage.
