How does a K-cup filling machine works?

A K-cup filling machine has six stations in order to fill a K-cup. These stations have their own functions:

1. Cup-Placement Station

At the cup-placement station, the K-cups are placed in their designated stack. Once the K-cup filling machine is turned on, the K-cups will be placed on the cup ring which is located on the rotary type table.

2. Filling Station

At the filling station, the K-cup will be filled with the material which is correctly measured for the required quantity in each cup. This is possible with the help of a spool valve. The materials are stored in a hopper which is placed at the top of the spool valve. Furthermore, the position of a cup is detected by sensors. If the cup is not detected, then no material will be placed as well. The filling process is automatic and the accuracy is around 0.5 – 1%. Usually, a K-cup filling machine can contain up to 30 liters of materials.

3. Lid Placement Station

Once the K-cups are filled, they will be then transferred into the rotary turret going to the lid placement station. The lids are taken by vacuum cup from the magazine. After which, the lid will be gently placed in the cup. Optionally, the lid can also be placed and snapped in the ready cup.

4. Sealing Station

After placing the lid of the K-cup, it will be then sealed using heat sealing or hot punch. This process is very quick and simple.

5. Data Printing Station

Right after sealing the lid of the K-cup, it will then be printed with on either at the top of the lid or at the bottom part of the cup. Usually, printing is done using heat. The details that are usually printed in a K-cup includes the manufacturing date, batch number, and expiry date.

6. Discharge Station

The sixth and the last station in the process of filling and sealing a K-cup is the discharge station. In this station, the sealed and printed K-cups will be discharged into a conveyor belt which usually measures 1 meter long for collection. Finally, the filled k-cups will be packed into cartons, ready to be delivered.

Types of K-Cup Filling Machine

Solid Filling Machine

Typically, solid filling machines are used in filling k-cups with powder or grain products such as milk powder, spices, instant cocoa, and chemical products.

Solid filling machines are classified into different types.

  • A Telescopic Pocket Filler is most suitable for K-cups which will contain solid products such as peas, ravioli, lentils, pasta, corn, dried pasta, dried meat and so much more.
  • Vibrating Cone Fillers are specially made for filing K-cups with difficult thread-like solid products such as stripped vegetables, green beans, and the like.
  • A Semi-telescopic filler can either have vibrating bushings or not. This solid K-cup filler is suitable for products such as peas, tomatoes, beans, cucumber, corn, lentils, and the like.
  • A multi filler, on the other hand, is for different types of medium-sized or small solid products.
  • A spice dispenser is used in filling products such as dried or granular vegetable and powdered or dried spices into a K-cup.

The process of filling is the same regardless of what solid product is being filled in a K-cup machine.

In the process of filling the K-cup with a solid product, the K-cup is carried by a conveyor belt towards the feeding screw at a set speed. The feeding screw and the inlet star are synchronized in order for the K-cups to reach the filling machine. A telescope directs the solid product and determines the quantity of the product which is to be filled to the K-cup as well. In the filling process, the solid products are settled inside the K-cup through pneumatic vibrators. Once filled, the K-cups will leave and will proceed to other production processes.

Liquid Filling Machine
