Auger Filling Machine Principle of Operation

This machine is safe and also easy to operate and is used by many industries.

Once oriented, the operator can use it for packaging a variety of products depending on the settings.

Below is how it operates.

  • The operator manually loads the bags into an in-feed magazine at pre-determined intervals. Do this carefully to facilitate proper filling once the machine is switched on. If you are using bottles, you will need to place them into a conveyor system.
  • The bag feeder roller the transports the bags inside the machine one after the. For automated machines, a robot arm using a vacuum grasps each bag and moves them to the grippers.
  • Dates and batch numbers are then printed on the bags if needed to appear on the packaged product. This is the work of inkjet or thermal printers, which are integrated into the machine.
  • Next, place the products on the loading area and switch on the machine.
  • The filling motor drives the auger at a pre-determined speed, facilitating the pushing of the products out of the tube.
  • While this is happening, the mixing motor also rotates the stirring bar attached to the agitation bar. This happens in a counter-clockwise direction to the auger.
  • The bags/pouches have a zipper, which is first detected. The bags are then gripped on the lower side, and the opening jaws open the top part gently.
  • Air is pushed out of the container being packaged to create space for the product to be filled into the container.
  • The auger filler then dispenses the product into the bags/ containers in pre-determined quantities.
  • It is the work of the agitation bar to make sure there is consistency in filling of the auger flights. The consistency facilitates the continuous trickling down of the products into the funnel through the trap door. This results in filling of the readily open containers.
  • A dust hood placed above the filling machine contains the spread of the dust particles. Regular cleaning is necessary to ensure the machine functions correctly.
  • Any air that might have remained in the package is slowly squeezed out using a deflator.
  • The machine then seals the bag and allows it to cool. It then discharges the sealed bag from the filling area to a receptor.

Key Features of Efficient Auger Powder Filling Machine

How to Improve the Accuracy of Auger Powder Filling Machine

This machine is considered to be efficient if the products being packaged arrives at the final stage quickly and safely.

For this reason, it is very crucial to work towards improving its efficiency.

There are several ways by which we can improve the accuracy of the machine, including:

Figure 10 Powder auger filler

Powder auger filler

· Using the Horizontal In-feed Screw

This is a unique technique.

It ensures the hopper consistently maintains the same and controlled required fill level all through the operation process.

The control is done from the level sensor in the auger hopper.

During the filling process, when the fill level goes lower than the recommended, the feed screw automatically turns on.

It then fills the hopper to maintain consistency in filling the right quantity of the products.

· Improve Hopper Fill Level

Inconsistency infill level results in varying weights of the product.

This compromises the quality of the product fill and therefore, requires more attention from the operator.

Thus, the auger tooling should be adjusted appropriately, cleaned and maintained to get the desired results.

· Ensure there is the Maximum Speed of the Auger

The recommended rotation of the auger should be three to four times for it to be able to fill a bag.

A good speed will promote accurate weight control.

Because the auger tooling is an essential part of this process, ensure it is working correctly.

Agitator must be set for a speed that can work best with the product being packaged.

Agitators are designed for specific products. For example, some can only work for non-free flowing products.

It guides and aids in pushing the product to the flights of the auger screw.

Once the agitator rotation speed is set, the accuracy of the fill is achieved.

Correct setting prevents the product from accumulating along with the hopper.

· Cleaning of the Machine

Dust accumulation on the machine can impede the machine function.

Therefore, regular cleaning of the machine also helps to improve its accuracy.

Auger Filler for Powder Metering Principle

There are two metering principles: structure and simulation results.

Structure of Auger Filler

The structure of an auger powder filler is made up of five parts.

These parts include the Drive motors, hopper, blenders, auger and auger funnel.

Servo motor powers the rotary fill of the auger through the power that is transmitted between them.

Several rotations are controlled by the PLC program controller depending on the weight value set.

The volume is then calculated according to product density.

This machine then rotates to complete individual metering and filling process.

Stirring motor works continuously as the product loads in the hopper through a conveyor.

The first thing that happens is that the drive motor waits for the fill signal to arrive.

It then starts rotating and ends the fill, weighs the feedback and calculates the next rotation angle of auger

Simulating Results

There are three principles here which include:

  • Velocity and pressure fields within the Auger groove
  • The effect of Auger rotating speed on the filling amount, and
  • Optimization of Auger parameters.

Let me shed more light on each one of them below.

Velocity and Pressure Field in the Auger Groove

The speed of the product placed in the Auger machine can be seen clearly during the rotation of the machine.

This is a bit complex since it does not comply with the speed mathematically calculated in the model.

This results in some shortcomings in the analysis.

Effect of Auger Rotating Speed on the Filling Amount

The higher the rotation speed of the auger machine, the more efficient the whole process of filling.

This is because the density between the powder particles decreases as it rotates faster.

Furthermore, it also increases the accuracy of product filling.

Optimization of Auger Parameters

During the packaging process, the main auger parameters are Auger thread distance, Auger thread angle, and Auger thread depth/diameter.

The auger thread distance is usually set to fit the actual fill quantity.

The auger thread angle determines the measurement efficiency of the machine.

With the consistency of auger thread distance and angle, it means the auger threads with varied angles acquire better angles. This may range from 16-25 degrees.

Different powder fillers which have different characteristics are supposed to have the individual specific adjustment of the three-parameter.

Two parameters are first pre-set, then the remaining is optimized to achieve the best measurement effect.
