Electronic tablet/capsule counters excel in the counting and packaging of granular materials across a variety of industries such as pharmaceuticals, chemicals, and food. Their precision and efficiency largely stem from the meticulous adjustment of various parameters. Below are the key parameters and adjustment essentials:
These are fundamental to accurate counting.
For photoelectric detection counters, sensitivity settings must be adjusted based on differences in particle color and transparency:
For light-colored or highly reflective particles, reduce sensor sensitivity to avoid miscounting due to ambient light interference.
For dark-colored particles, increase sensitivity to ensure stable detection.
For image recognition-based systems, it is important to clearly define the particle recognition criteria, such as shape and size thresholds. By capturing sample images and using software algorithms to continuously refine these parameters, the counter can accurately distinguish target particles from impurities or fragments—achieving precise particle identification.
These impact the balance between efficiency and accuracy.
When material flow is consistent and particles are well dispersed, the upper limit of counting speed can be gradually increased. However, excessive speed may lead to particle buildup or missed counts.
Typically, the machine should start at a lower speed. After observing the performance, gradually increase the speed to find an optimal point where production requirements are met without compromising accuracy.
For small or easily rolling particles, a lower speed setting is advised compared to large or uniformly shaped particles to minimize dynamic counting errors.
These should not be overlooked.
Mechanical vibrations or changes in drop height can cause minor counting deviations. In such cases, compensation values need to be set.
After repeated testing, compare the displayed count with the actual particle count:
If the machine undercounts, apply a positive compensation value.
If it overcounts, apply a negative compensation.
Fine-tune the compensation gradually until the error margin is minimized. For example, when the vibrating feeder operates under unstable conditions, appropriate compensation can help maintain consistent counting accuracy between batches.
These are especially crucial for multi-channel counters.
Depending on the total material volume and packaging requirements, evenly distribute the counting tasks among all channels.
Properly set the activation sequence and time intervals for each channel to avoid interference or material contention between channels.
This coordination ensures all channels work efficiently together, enhancing productivity and throughput.
By mastering these parameter adjustment techniques, electronic counters can operate smoothly under complex conditions—ensuring precise metering and packaging of granular materials.
