With the rapid development of the times, people’s living standards continue to improve, people are paying more and more attention to their health, and the demand for drugs is also increasing. Therefore, the pharmaceutical industry continues to put forward higher requirements for pharmaceutical production equipment, and the counting machine is Important equipment in the pharmaceutical production and packaging process. The counting machine has also developed from an electronic counting machine to a photoelectric counting machine with higher counting precision and higher degree of automation.

Application of Capsule Counting Machine

Capsule counting machine is widely used in medicine, industry, chemical industry, food and other industries. It can be used for counting and bottling solid preparations, such as pills, sugar-coated tablets, plain tablets, soft and hard capsules and other shapes of medicine granules. The counting machine can be used independently, and can also be used with other supporting equipment such as bottle unscrambler, paper stopper, capping machine, sealing and labeling machine to form a counting bottle bottling line.

Working Principle of Electronic Counting Machine

The electronic counting machine adopts advanced vibrating multi-channel feeding, computer control, dynamic scanning counting, system self-checking, fault indication alarm, automatic shutdown and other technologies. It meets GMP requirements. It is a medicine counting and filling equipment integrating light and motor .

Working Principle of Photoelectric Counting Machine

The photoelectric counting machine uses a photoelectric sensor to count. A pair of photoelectric sensor components are installed on both sides of the counting channel. One end is the signal transmitter and the other is the signal receiver. The optical signal transmitter sends out a beam signal. When the medicine particles pass through the counting channel, the beam If it is blocked, the photoelectric sensor will generate electrical pulse signals. The number of electrical pulse signals emitted is the number of medicine particles.

Difference between Electronic Counting Machine and Photoelectric Counting Machine

The first generation of electronic counting machine:

The first-generation electronic particle counting machine is relatively small, and mainly adopts the principle of photoelectric particle counting sensor, which is suitable for counting small objects. It does not require high speed, non-contact measurement, and the position where the object falls.

The second generation photoelectric counting machine:

The appearance of the photoelectric counting machine is a real leap in high-speed counting. It literally liberates labor, reduces the cost of use, and fully realizes the full automation of mechanical packaging equipment in the pharmaceutical industry.

The technical working principle of the photoelectric counting machine is as follows: through the initial adjustment of the vibrating feed plate, the medicine particles in the hopper continuously vibrate forward along the vibrating plate track until they fall from the front photoelectric detection channel and touch the photoelectric sensor to start working and counting. When the number of medicine particles reaches the predetermined number, the PLC will give the electric valve signal to close the discharge port, and the counted medicine particles will fall on the bottle at the outlet to realize the counting function of the particles.
