It also saves time by allowing the operator to perform other duties as it continues to count the pills.
The machine aids in the accurate counting of pills.
Its accuracy stands at 100% (except when it develops faults due to dust accumulation in the tray sensor window).
This helps in ensuring that patients in nursing homes and pharmacies get the right medication and dosage at the right time.
Components of Pharmacy Pill Counter Machine
There are five different components contained within the operation circuit of a pharmacy pill counter machine.
They include the keypad, micro-controller PIC16F877A, 16*2 LCD, DC motor and IR LED and IR sensor.
Pill counter sample structure
The keypad is a membrane with non-moving parts that has sixteen buttons which are in matrix form.
It has digital numbers from 0-9, A, B, C, D and characters * and #.
It is used to key in the number of pills required to be packaged in the system.
It has eight pins of data lines connected to eight pins of the controller.
From the keyboard, the controller reads the data and calculates the desired tablet quantity displayed on the liquid crystal display.
This component has a PIC pin assignment for control system PIC16F877A with five ports assigned A, B, C, D, and E.
It is part of the mid-range family of PIC microcontroller device.
When the microcontroller is pushed, DC drive motor starts the counting machine so that it can perform its function.
· LCD module
This is a screen where the counting numbers are displayed.
Here a PC 602-F is used to connect six micro-controller pins and two backlight pins for supplying power.
Through the D4-D7 pins of LCD, data is sent from the controller to the screen.
· Brushed DC motor and Vibration motor
These are electric motors designed to run from a direct power source.
Brushed DC motor was the initial driver for mechanical loads.
In this machine, it rotates the plastic circular plate carrying a tablet.
It is controlled by a relay driver circuit which is connected to the micro-controller.
The vibration motor facilitates the falling of tablets into the rotary plate.
The PIC controller controls this process. It works the same as a rotary motor.
· IR LED and IR sensor
These are sensors. IR LED generates rays that operate the sensors and also helps in the passing of pills in a keyway.
Inside this sensor, there is an infrared detector.
Through the reaction to infrared radiation, both thermal and photonic detectors capture the passing pills.
It then sends the data to the micro-controller for counting of numbers.
The IR sensor crosses the pills by sending digital data of 0, 1, 2, and 3 to micro-controller.
How the Pharmacy Pill Counter Machine Works
When you are ready to count pills using this machine, pour the tablets into the machine.
In the keypad digit numbers 0-9, key in the number of pills you want the machine to count.
The LCD will display a welcome screen and a quantity of pills to be packaged.
In the PIC controller, press the start button to drive the DC motor which is the vibrating and counting motor.
At the bottom of the machine, push the button * so that the pills can begin to move.
The IR sensor will then begin to sense the passing pills and send digital data to the micro-controller.
For example, when one tablet passes, it sends 0 data, then 1, 2, until counting is completed as designated.
The numbers being counted are displayed on the LCD module.
Once counting is completed, the counted pills will be deposited onto the top drawer.
Remove this drawer and the excess pills will fall into the second drawer where they will be returned to the inventory.
Types of Pharmacy Pill Counter Machines
There are numerous types of pharmacy pill counter machine.
We can broadly categorize them as automatic and manual Pharmacy pill counter machines.
Let us have a more in-depth look at these two categories.
Automatic pharmacy pill counter machine
This machine generates fast, accurate pill count in a short time, thus saving money.
Some of these machines have the ability to count pills in bulk.
It’s ideal for counting inventories since it works with a speed of up to 500 or even up to 800 pills per minute.
Automatic pill counting machine
In addition to these, it counts all shapes and sizes of both tablets and capsules.
Some automatic pharmacy pill counter machines have a digital touch screen.
This is used to control turret speed, pressure, fill depth, tablet thickness, and speed for accuracy, ease of use and efficiency.
This machine automatically adjusts all its key parameters.
It also has an emergency stop button for safety features.
Since it does every work during the counting of pills, the operator concentrates in performing other tasks.
This machine is an intelligent one and is able to do both counting and filling.
Its high-speed PLC system has control over the entire process of counting, filling, and monitoring.
Bottles can be placed by conveyer belt and automatically filled with high rates that vary at a fast responding speed.
The automatic pharmacy pill counter machine is handy for quantitative packaging of pills.
It is an essential instrument in pharmaceutical companies, scientific research units, and small and medium batch laboratory productions.
This machine uses electromagnetic vibration effect, and it’s easy to use.
Advantages of automated pharmacy pill counting machine
Some of the main advantages of this machine include:
Pill counting machine
The machine can count in bulk and faster. It does the counting, filling of bottles and packaging of pills into various packages.
This means the staffing costs are significantly reduced since the machines perform most of the tasks.
2) No mis-count of pills
It’s made in such a way that it eliminates any possibility of miscounting that may not be avoided with manual counting.
Causes of errors during manual pill counting like disruptions cannot corrupt the machine.
When you stop the machine, you can just resume and no error will be experienced.
The customers don’t have to wait for a long time to be served.
It does the work, and the operator can continue with other tasks.
Also, you don’t have to stop and start counting all over again as when errors occur in manual counting method.
Furthermore, you will not stop what you are doing to engage in dispensing pills into vials or bottles.
This is because the machine does all that on your behalf.
It also works at a very high-speed counting between 500-820 pills per minute.
This allows inventory counting and is ideal for large scale pharmaceutical companies, busy hospitals, and pharmacies.
During manual counting, you may experience confusion due to some pills that look similar.
This automatic machine does not have this problem.
Apart from this, the safety of the pills is guaranteed because medications are in a sterile environment.
This reduces pill contamination that often happens when we use the manual counting process.
Potential medicine thieves also can’t have access to these pills if they don’t know how to operate the machine.
5) Customer care
As the robots fill in the prescriptions, you can attend to patients at the pharmacy.
You can talk to patients about their medication and home addresses.
The pharmacist can also answer their questions so that the patients’ quality of life can improve.

· Many design options can be confusing to operate
Automatic pharmacy pill counter machines are of many types, and each has its operating procedures.
The most advanced once might be a bit complicated to use especially if you are not acquainted with it.
· Dust accumulation may cause sensor error
Whenever there is dust accumulation in the machine tray sensor window or when it is damaged, the machine is bound to make errors.
This problem may persist unless the operator discovers it.
In a pharmacy, many patients may end up receiving the wrong medication if it takes longer to identify and sort the problem.
· Advanced designs may require training to operate
Not everybody can be trained to use this machine in a pharmacy.
Because of this, there is a possibility of delayed services should the machine break down in the absence of the operator.
· Initial cost of investment
These machines are relatively expensive as compared to the manual ones.
Manual pharmacy pill counter machine
This is a low-cost handheld tray that has two parts.
The lower part is a plain tray without holes while the upper part has holes.
These holes can be of different shapes and sizes suitable for counting of both tablets and capsules.
Manual pill counting machine
This machine has a different number of counting holes ranging from 5 to 250 holes.
When you pour pills on top and shake, the pills will find their way into the holes.
The excess ones will fall into a wider tray placed beneath this counter machine.
A Counter of 50 holes, will count 50 pills accurately.
You have to inspect if all the holes have been filled with pills before you can ascertain its accuracy.
You can then hand-package them into bottles and continue the process until all the pills are counted.
This is ideal for small pharmacies, trials, and hospitals that are not very busy.
They can also work well in parts of the world that are not highly populated.
It is strong and very friendly to operate.
In addition to these, it is easy to use, maintain, compact and light in weight.
Manual pill counting equipment
Advantages of manual pharmacy pill counter machine.
- It is cheap to purchase and maintain as compared to the automated one.
- This machine is much easier to operate because it is not as complicated as the automated one. Therefore it does not require sophisticated training for the operator.
- Since this counter is very simple, it is easier to find out if it has developed any problems that could compromise its use.
Disadvantages of manual pharmacy pill counter machines
- Even though the manual machine costs less, its efficiency is very low as compared to the automated one. It cannot carry out bulk counting, unlike the automated counter machine.
- Also, the machine does not perform the filling of bottles. You have to pick the counted pills and manually fill the bottles or vials.
- This machine requires the full attention of the operator throughout the process. He has to remove counted pills, package them and make manual prescriptions.
Therefore, with the use of this machine, any other task must be suspended until pill counting is completed.
Pill counting line
- More pharmacists are needed because the tasks performed by automated machine are taken care of by the staffs. This increases the cost of remuneration for staffs.
- A manual machine is not time-saving because it is aided by manpower. It consumes a longer time to count, prescribe, and package the pills into bottles. Therefore it is not very efficient and is only ideal for small pharmacies.
- The drugs may be contaminated during packaging as this is done manually. Also, potential thieves may have access to pills during packaging, leading to losses.
- This handheld machine cannot detect fragmented pills. Therefore, there is a possibility of over-count when fragmented pills get into the holes with the whole ones.
- You have to buy many handheld counters for different prescription. For example, you may have for 10 holes, 20 holes, and 50 holes among others. This is because the maintenance of accuracy in the counting process is very crucial.
Features of Pharmaceutical Pill Counter Machine
This machine has several features which are tailored towards pharmacist applications.
Technical specification of pill counter
· Automatic product setup
New product calibration is done when products are placed on a special calibration tool and scanned by a camera.
It automatically sets all tablet data like size and shape among others.
This is important because it results in a simple and accurate setup procedure that helps in avoiding costly human errors.
· User-friendly PC based operation
Bulk counting machine operates through a color touch panel PC based system.
Its internal and external functions are controlled through one HMI in a matched standard.
Once you are trained on how to use it, you can always operate it.
· GMP designed without blind spots
It is designed for the operator to follow and observe each unit of the product from the hopper to the bottle.
This is very important because it significantly reduces the risk of cross-contamination of pills.
· Easy cleaning and changeover
Contact parts of this machine are designed for tool-free release in accordance with GMP design.
It has small light-weight parts that make its cleaning process fast and easy.
Also, it has a spare contact part kit that allows for a five-minute changeover from one product to the other.
This is far much better than the 1-hour changeover previous machines.
In-process cleaning can be done after every 8 hours or when the machine is under extreme dust conditions.
· Capability for detecting fragmented pills
Its ICU 1-40 has a vision-based system that provides automatic and accurate pill detection.
This machine detects broken pieces as small as 0.5 mm.
It detects whether broken pills have been poured into the vial or weighing boat.
Its unique algorithm has the ability to detect if a certain percentage of average weight has been added.
The scale will send a notification to the operator so that he/she can remove the fragment.
A network connected system will automatically send an e-mail notification of when it happened and where the fragment was found.
When a tablet is rejected either due to breakage or size variation, the container to be filled will be halted.
It will then be sent to reject station and this saves both time and money.
· Accuracy in the counting of pills
This machine is a technological solution.
The counting is done in bulk by an advanced real-time mathematical vision-based algorithm.
It gives the most accurate (100%) counting results in pill counting industry.
It can adjust pill weight that may vary over time when transiting from one LOT to another.
· Insensitivity to dust
The counting machine is separate from the truck and this aids in the reduction of dust accumulation.
Also, the vision-based system has a magnetic flap connection that minimizes dust effect on the machine.
Another advantage here is that once the dust has accumulated on the counting unit, its system will alert you.
· RX verification
These machines have NDC verification that safely creates a check ensuring that the drug being counted matches the one prescribed.
It prevents human error from occurring and the supply bottle is scanned and compared against RX label.
Matching of the two NDC codes will call for continuity in the pill counting process.
· On-screen instructions
Instructions on the screen are used to take the first time users through on how to count the pills using the machine.
It is simple and there is no room for errors once you follow the instructions as displayed on the screen.
This saves time especially for people who may be using it for their first time.

Troubleshooting Pharmacy Pill Counter Machine
Here are some possible errors you encounter in pharmacy pill counter machine:
|Challenge/ problem||The cause of the problem||Possible solution|
|Unit counts by itself||It’s caused by tablet dust or residue on the detector glass window. It can also be caused by a cracked detector glass window.||The detector glass window should be thoroughly cleaned. Also, the cracked detector glass window should be replaced.|
|Over-count of pills||This happens when there is pill fragmentation or tablet dust on the detector glass windows.||For tablet fragmentation, check counter medications.|
You should also ensure the detector glass window is thoroughly cleaned with mild soapy water and alcohol.
|Undercount of pills||It happens when you pour out pills into the funnel too fast. It happens also when they are poured directly into the funnel hole.||The remedy here is to pour the pills into the funnel slowly to prevent the “pour slowly” indicator from activating.|
|When the tray is pushed in, the display reads “—-” instead of “0000”.||The reason could either be that the tray is not fully inserted or the tray sensor window might be dirty.||The solution here is to insert the tray fully or clean the tray sensor window in-case it is dirty.|
|When the display reads “0000” even when the counting tray is not fully inserted||This happens when the tray sensor is either dirty or damaged.||Clean the tray sensor window if it is dirty or if damaged, repair it.|
This machine is very crucial in the medical industry particularly in the current world where there is a population explosion.
