So how does the tablet capsule rotary counting filler work? How does an accurate counting work? This paper will introduce the equipment structure, workflow, counting technology and intelligent control in detail.
1. What is a tablet capsule rotary counting filler?
Tablet Capsules Rotation Count Filling Machine is a packaging equipment for automatic counting and filling of solid preparations.
Pharmaceutical companies
Healthcare product manufacturing enterprises;
Nutritional processing plant
Food and candy manufacturing
The device can automatically count and pack pills or capsules into plastic bottles, glass bottles or other packaging containers based on a predetermined quantity, and can form a complete automated packaging production line with bottle splitters, sealing machines, labeling machines, sealing machines, etc.
Compared with manual packing, automatic counting filler has advantages of speed, small error, high stability and strong continuous production capacity.
Basic structure of tablet capsule rotary counting filling machine.
In order to achieve accurate counting and stable filling, the device usually consists of multiple functional modules that work together to complete the packaging process.
1. Automatic feeding system
The feeding system is responsible for the uniform delivery of tablets or capsules to the counting area.
Common methods include:
Vibration feeding
Improved delivery of materials
Automatic replenishment of storage tanks
Steady feed can avoid product accumulation or blockage and provide a basis for accurate counting.
2. Rotating material sorting mechanism
Rotating material sorting mechanism is an important component of equipment.
By rotating the disc or dividing the material channel, the product is evenly dispersed so that the tablet or capsule remains in a single column and arranged in an orderly fashion in the counting area.
This design can reduce product overlap, improve counting accuracy, and accommodate products of different sizes and shapes.
3. Optoelectronic counting system
The counting area is usually equipped with high-precision photoelectric sensors.
As the pill or capsule passes through the detection area, sensors can quickly identify each product and transmit the signal to the control system for a real-time counting.
Because of the fast response speed of the sensor, the detection accuracy is high even when operating at high speed.
4. Automatic filling mechanism
After the counting is completed, the device automatically opens the outlet to drip the specified quantity of product into the packaging container.
The system then moves on to the next cycle, continuing to count and fill, achieving continuous automated production.
3. The working principle of tablet capsule rotating counting filling machine.
The device workflow usually includes the following steps.
Step 1: Automate feed.
Pieces or capsules enter the bin first and are uniformly transferred to the rotary feeding system under the action of a vibrating feeding device.
The feed speed is automatically adjusted by the control system to ensure the counting is stable.
Step 2: Product arrangement
The rotating mechanism rotates continuously, distributing the product evenly across multiple channels.
This avoids:
Product overlap
block of block
pile up
Ensure that each product passes through the test area in sequence.
Step 3: Accurate Counting
Sensors record a signal each time a product passes through a tablet or capsule as it passes through the photoelectric detection area.
PLC control system perform real-time statistics based on a set quantity, such as:
30 pills per bottle
60 pills per bottle
90 pills per bottle
120 pills per bottle
Once the set flow rate is reached, the system immediately controls the action of the discharge mechanism.
Step 4: Automatic filling.
After counting, the product automatically falls into the bottle.
The conveyor belt then takes the bottle to the next step, such as:
Add desiccant
screw cap
Aluminum foil seal
Labels
Packaging
The whole process does not require manual intervention and the packaging is fully automatic.
4, How do devices count accurately?
Accurate counting is the core performance indicator of rotary counting filler, the accuracy of which depends on the following key techniques.
1. High precision photoelectric sensing technology
Modern devices often use high-speed photoelectric sensors that can quickly identify each product passing through the detection area.
Compared with traditional mechanical counting methods, photoelectric detection has the following characteristics:
Rapid response speed
High detection accuracy;
Little wear and tear;
Good stability
Even at high speeds, the accuracy of the counting remains high.
2. Intelligent PLC control system
PLC control system is responsible for the coordinated operation of the whole equipment.
It allows real-time processing and automatic control of sensor feedback:
Feed Speed
Counting
Discharge time
Transport cycle time
Intelligent control can not only improve production efficiency, but also reduce human error.
3. Multi channel synchronous counting
In order to increase production capacity, many devices are designed with multiple channels.
Multichannel simultaneous work can be achieved by:
Increase in output
Faster packaging speed
A more stable counting
The system will automatically synchronize data from each channel to ensure consistency in overall packaging.
4. Automatic exclusion of anomalous products
Some high-end devices come with detection functions.
If found:
Empty bottles
Lack of food;
Multigrain
material blockage
The system automatically alerts and deletes non-conforming products.
This feature helps to increase the output of finished products and reduce subsequent quality risks.
5, Intelligent automation technology to further improve packaging quality.
With the development of intelligent manufacturing, modern tablet capsule rotary counting filler has been introducing digital and automation technologies.
For example:
Human-machine interface (HMI) is convenient for parameter setting and operation monitoring.
Servo drive system improves the operation stability of the equipment.
Automatic fault diagnosis function to help locate problems quickly;
The data recording and traceability function meet the quality management requirements of the pharmaceutical industry.
Some of the equipment can also be connected with MES and ERP systems to realize real-time management of production data and provide support for digital production of enterprises.
6, What factors affect the accuracy of the count?
Despite the high degree of automation of equipment, the accuracy of the count is still affected by the following factors:
Product specification Differences
When there are significant differences in the size, shape and weight of a pill or capsule, it is necessary to adjust device parameters to ensure smooth feeding and accurate testing.
Feed stability
Too fast or too slow feed will affect the alignment of the product, leading to overlap or leakage, so it is necessary to maintain uniform feed.
Sensor status
If dust or powder is attached to the surface of the photoelectric sensor, this may affect the detection effect and should therefore be cleaned and calibrated regularly.
Maintenance of equipment
After a long period of operation, the rotating mechanism, conveyor and transmission system may be worn out. The development of preventive maintenance plans helps to maintain a stable counting accuracy over the long term.
Conclusion:
Tablet capsule rotating counting filler realizes high speed, high precision and automatic production of solid agent packaging process by automatic feeding, rotating sorting, photoelectric detection, PLC intelligent control, automatic filling and so on. Compared with traditional manual counting methods, it can not only significantly improve packaging efficiency, but also reduce human error and ensure consistency in the quantity of each bottle.
