Principle of automatic tablet counting machine

  The automatic tablet counting machine uses the principle of photoelectric effect to input the working signal generated by the infrared dynamic scanning sensor when the medicine particles fall to the FPGA high-speed microprocessor, and realizes the counting function through the cooperation of the circuit and the program. Suitable for soft and hard capsules and transparent capsules, tablets, pills and other solid medicine granules. The sliding track of the medicine particles adopts a three-layer ladder type, and the medicine particles go downstream one by one, and the distance between the medicine particles and the medicine particles will be set according to the program to avoid overlapping.

  Pour the medicine pellets into the top hopper when working, and adjust the primary, intermediate and final stage vibrating feeders appropriately, so that the piled medicine pellets in the hopper will gradually slide along the vibrating groove plate into a continuous strip and slide down to the discharge opening. . Then, the drop detection channel is used for each drop detection channel, using the principle of photoelectric effect to input the working signal generated by the infrared dynamic scanning sensor when the drug drop is falling to the FPGA high-speed microprocessor, and the counting function is realized through the cooperation of the circuit and the program.

1. Working principle: When working, pour the medicine granules into the top hopper, and by appropriately adjusting the primary, intermediate and final stage vibrating feeders, the piled medicine granules in the hopper gradually become a continuous straight line along the vibrating groove plate. Go down to the blanking opening. Then, the drop detection channel is used for each drop detection channel, using the principle of photoelectric effect to input the working signal generated by the infrared dynamic scanning sensor when the drug drop is falling to the FPGA high-speed microprocessor, and the counting function is realized through the cooperation of the circuit and the program.

2. Performance characteristics: 　　

Suitable for soft and hard capsules, transparent capsules, tablets, pills and other solid medicine granules; 　　

According to the requirements of GMP standards, most of the parts in contact with drugs are made of AISI316 stainless steel, and the body is made of AISI304 stainless steel or PET , It is very convenient to use and maintain; 　　

The machine structure is tight, the electrical control and other parts are all sealed, the screen is pneumatically locked, and the embedded buckle structure is adopted, which is easy to disassemble and clean.　　

During the normal production process, there is no need to be supervised by a special person, and the machine has various protection devices; 　　

3. Structural features

1. Operating system: 　　

The introduction of mature high-speed electronic chip technology from well-known foreign manufacturers, an operating system based on MCU high-speed microprocessor technology with full Chinese dynamic graphics display, parameters can be set or adjusted on the.　　l Automatic fault diagnosis and real-time monitoring alarm display system, and can store multiple sets of parameters, which can be called directly when changing products.

 2. Feeding device (optional accessory): 　　

This device is easy to operate, stable, reliable, easy to disassemble and assemble, and safe to use; 　The material barrel is made of AISI316L stainless steel, and the material is sealed for conveying materials, which is less dusty and conforms to GMP; 　　

The weight range is wide, and the performance has reached the level of similar foreign products; 　　It can reduce the labor intensity of workers and improve work efficiency.

3 Granule feeding mechanism: 　　

Adopt three-stage vibrating disk electromagnetic oscillation, the vibration frequency is adjustable, and the speed is fast to ensure the medicine particles travel fast; 　　

DC vibrator, stable vibration, can make the medicine particles, especially irregular tablets Running smoothly to avoid false counting; 　　

The sliding track of the medicine particles adopts a three-layer ladder type, and the medicine particles go downstream one by one. The distance between the medicine particles and the medicine particles will be set according to the program to avoid overlapping. ；　　

Three-stage dust collection design, the dust between the falling layers of the medicine particles is completely sucked out to avoid pollution. (Vacuum cleaner is optional)
