Chapter 14:Functional Principle of fully capsule filling machine & semi-auto capsule filling machine

The NJP Series utilizes a high-precision, intermittent rotary motion to achieve automated encapsulation. The process is divided into twelve distinct stations to ensure maximum accuracy and hygiene.

14.1 The 12-Station Encapsulation Cycle

Station 1 & 2: Capsule Feeding & Vacuum Separation: Capsules are fed vertically into the main board assembly. A vacuum separation system then draws the capsules into the mold holes, effectively separating the capsule body from the cap.

Station 3 & 4: Offset Preparation: The upper mold rises while the lower mold extends outward, creating a strategic offset required for the subsequent filling process.

Station 5: Precision Dosing: The tamping rod pushes a pre-compressed powder plug (formed through a five-stage tamping process) into the waiting capsule body.

Station 7: Defective Rejection: Any capsules that failed to separate in the first stage are identified and removed by a specialized waste suction nozzle.

Station 9: Capsule Joining & Locking: The upper and lower molds align as the capsule joining push rod locks the cap and body together securely.

Station 10 & 11: Finished Product Discharge: Successfully locked capsules are ejected through the finished capsule outlet for collection.

Station 12: Automated Cleaning: An air-blowing column combined with a vacuum system cleans the mold holes, preparing them for the next production cycle.

14.2 Semi automatic capsule filling machine working principle

The semi-automatic series (such as the CGN-208 series) is designed for pharmaceutical R&D, pilot plants, and medium-scale production where flexibility is essential. It combines automated material feeding with manual tray management to provide a cost-effective yet precise encapsulation solution.

Step 1: System Initialization & Material Loading

• Inspection: Perform a pre-operational check to ensure all components, especially the loading trays and vacuum seals, are in optimal condition.

• Loading: Load empty capsules into the capsule hopper and the active ingredients (powder or granules) into the powder hopper.

• PLC Configuration: Power on the machine and input critical operating parameters—such as vibration frequency and auger rotation speed—into the PLC control system to ensure batch consistency.

Step 2: Vacuum-Assisted Orientation & Separation

• Rectification: Empty capsules are fed from the hopper through a delivery system that aligns them vertically into the round capsule tray (loading ring).

• Vacuum Separation: The machine utilizes a vacuum-assisted station to pull the capsule bodies into the lower tray while the caps remain in the upper tray.

• Manual Transfer: The operator separates the upper and lower trays; the cap tray is temporarily set aside while the body tray is moved to the filling station.

Step 3: Auger-Driven Dosing & Filling

• Precision Filling: The body tray is placed on the rotating filling table. The machine initiates the flow of medication through an Auger Screw mechanism.

• Weight Control: The fill weight is determined by the speed of the auger and the rotation of the table. This system allows for precise dosing across a wide range of material densities.

• Automatic Retraction: Once the 360-degree filling cycle is complete, the filling nozzle automatically retracts to prevent powder spillage.

Step 4: Mechanical Locking & Product Discharge

• Alignment: The operator repositions the cap tray directly onto the body tray.

• Pneumatic Locking: The joined trays are moved to the compression zone, where pneumatic pressure is applied to lock the capsules to their specified "locked length."

• Ejection: The final step involves discharging the locked capsules for de-dusting, polishing, and final quality inspection.

Chapter 15:How to use a fully & semi-automatic capsule filling machine?

 15.1 Operate steps of the fully automatic capsule filling machine 

You will refer to below steps to operate the machine well:

AIPAK NJP-1200D capsule filling machine

Check whether all parts of the machine and equipment are in good condition.

According to the process requirements, select the disc specification, powder or particle filling system.

Installation and adjustment: the support and the material tray shall be kept parallel, and the filling rod shall be perpendicular to the support, so as to ensure that the filling rod can freely enter and leave the filling hole of the material tray.

Loosen the set screw, turn the lock nut to the required height, then tighten the screw and nut, and adjust the height of the filling seat.

After all the safety settings are correctly equipped and adjusted, turn the machine 1-3 times in the running direction with the handwheel without capsule and medicine.

And then, under all normal conditions, put the capsule and medicine powder (or particles) into their respective containers respectively, with the filling height of 30mm below the edge of the container.

Adjust the depth of the filling rod inserted into the material tray. The large filling volume of the capsule is determined by the size of the capsule, the height of the material tray and the compaction degree of the filling rod to the powder.

Adjust the height of the filling rod.

In the beginning, the lower end faces of six groups of filling rods shall be on the same

horizontal plane.

The insertion depth of the filling rod is determined by the thickness of the material tray.

The particle filling system relies on the rotating adjusting shaft to move the adjusting parts left and right, and achieves the purpose of adjustment through the volume change. Start the machine and it will work normally.

Protection of filling mechanism: check the metering bucket regularly and remove any sediment stuck on it.

Apply a thin layer of grease to the track on the convex roller once a month. Gear and groove cam shall be cleaned and coated with grease once every two weeks.

15.2 Steps to operate a semi-auto capsule filling machine

As the above functional principle, you will easy to understand how to operate a semi-automatic capsule filling machine.

Below is more details for your reference:

Press the green button in the "power switch" to turn on the power.

Slowly adjust the "vibration strength adjustment knob" and turn it clockwise.

At this time, the finishing disk, which is connected with the "vibration support", starts to vibrate. Touch the finishing disk with your hand and adjust the vibration strength according to your feeling.

Put the powder-filled capsule shell into the "powder-filled capsule shell finishing disk", about 300 capsules each time. Put the capsule cap into the "capsule cap finishing plate", about 300 capsules each time.

The finishing plate is made of plexiglass plate, on which there are many circular holes with big upper and small lower funnel shapes, the diameter of which corresponds to the diameter of the capsule number.

At this time, the capsule shell of the working platform plate moves stably and slowly, so that it can enter the hole of the platform plate one by one.

In about 30 seconds, the powder-filled capsule shell and capsule cap fall into the round hole with the opening facing up. If the individual opening is facing down, the capsule cap can be used to press the sleeve down gently, and then the sleeve can be pulled out.

Horizontally hold the connecting plate of powder loaded capsule shell, push it in the lower part of the finishing plate, the powder loaded capsule shell in the finishing plate will fall into the circular hole of the connecting plate.

And then take out the connecting plate. In the same way, take out the capsule cap with the capsule cap connecting plate.

A powder square plate with a bottom area of 500 × 500mm and a height of about 10 mm on four sides can be prepared in advance, which is filled with powder, and the connecting plate of powder-filled capsule shell can be placed in the powder square plate horizontally. Then cover the plexiglass frame matched randomly on the powder filling capsule connecting plate, put the powder into the frame with a small bucket shovel, and fill the powder with a scraping on the edge of the frame, and scrape off the excess powder.

Use the capsule cap cover set plate (as shown at the end of the figure, there are round holes on the set plate), put it on the capsule cap cover joint plate, with alignment holes, easy to place.

Turn over the capsule cap connecting plate, make the opening of the capsule face down, and cover it on the powder loaded capsule shell connecting plate, which also has a contraposition hole, so it is easy to cover.

Put the assembled capsule plate into the cavity under the "capsule cap forming plate", pull down the "pressing rod" with your hand and put it in place, do not need to be careful of excessive force, because there is a positioning mechanism to control the pressing height.

Take out the sheathed capsule plate, pour out the capsule, and fill it. You can cycle to the next board.

Chapter 16:Fully vs. semi-automatic vs. manual capsule filling machine
