Doypack Packaging Machine Filling Mechanism

The design of this packaging machine allows it to utilize different filling mechanisms, which mainly include the following;

Volumetric Filling

It is a type of filling mechanism that enables the equipment to fill doypack bags with a uniform product quantity through a time-based filling principle.

In essence, it implies that volumetric fillers guarantee accurate and consistent product filling irrespective of discrepancies in the containers’ interior volumes.

Auger Filling Mechanism

This mechanism fills the exact product volume in the doypack as desired.

Ordinarily, it is regulated by corresponding pulses from the machine’s auger shaft driven by the servo motor unit.

The filler dispenses a set product volume into the package.

Net Weight Filling

In this doypack packaging mechanism, gravity, vacuum, or pressure play integral roles in determining the efficiency of product filling.

Essentially, the desired product fill level is determined by the equipment to enable filling of doypack packages accordingly.

Pump Dosing

It entails using a pump that draws a predetermined amount of liquid into its chamber and injects the product in the process.

The pump used in this process is driven by an electric motor installed in the machine with a regulator that switches pump on and off to control flow.

Sealing Mechanism In Doypack Packaging Machine

The notable sealing mechanisms used in this packaging equipment include the following;


This mechanism mainly uses chuck cappers that place a cap on doypack container by sending it through the machine to enable the moving parts to spin the cap and seal it tightly.

In this sealing mechanism, the container maintains a continuous motion rather than stopping at a spin station.

Heat Seal

It entails sealing the doypack container using heat and pressure.

This method offers direct material contact that utilizes a constantly heated die or sealing bar to apply heat to a particular path to weld the material.

Ultrasonic Sealing

This sealing technology utilizes acoustic vibrations to produce heat at a molecular level inside the film itself.

Ordinarily, these vibrations formed with sonotrode and an anvil trigger the molecules in the packaging material to start moving.

Primarily, it is the dynamic shear stress created by the ultrasonic vibrations that deform and generate heat due to friction between contact parts.

How Doypack Packaging Machine Works

Here’s the step-by-step process of doypack packaging machine’s working principle;

1) Bag Loading

Preformed doypacks are loaded into the magazine often manually by the operator.

A roller then feeds the bags into the equipment automatically for further processing.

2) Bag Gripping

The proximity sensor detects a bag’s presence at the end of magazine.

An arm grasps the bags using vacuum suction and loads them into the rotary “belly” of the equipment, then the fan sets in.

3) Optional Printing

If the bag needs lot codes, dates, or any other vital information, a printer is set to add the details to each bag as they pass.

4) Zipper Opening And Detection

The vacuum suction pads in this station gently grasp and pull the bottom portion of the bag to open.

An arm grasps top section of the bag and opens it fully.

This station also contains a sensor that detects whether the bag is loaded correctly or at all.

Should it fail to detect a bag, the filling and sealing steps hardly engage for the specific bag.

5) Optional Gas Flush

Most various product manufacturers are concerned with maintaining efficacy, product texture, and extended shelf-life.

Thus, oxygen, in most instances, tend to be the main culprit likely to affect all these elements negatively.

Hence, gas flush station pumps harmless nitrogen gas into the bag to displace ambient oxygen.

The bag is then sealed to suppress the low oxygen level further and create an ideal atmosphere suitable for perishable products.

6) Bag Sealing

The filled bag moves to a sealing station, which has two hot seal bars that come together over top of the bag.

Such seal bars bond and pack the material together and create a sturdy seal.

7) Bag Discharge

The station then conveys finished bags out of the equipment for further processing.

Types Of Doypack Packaging Machine

They are available in different varieties, but the main ones include the following;

VFFS Doypack Packaging Machine

Troubleshooting Doypack Filling And Sealing Machine

At times, doypack filling and sealing equipment tend to portray some malfunction or merely throw a specific error code during or after operation.

Of course, such cases usually arise from the environment, bag, product loading, and other aspects of the machine.

Nevertheless, here are the common troubleshooting techniques you may consider when such issues arise in the machine;

Failure Of Bags To Feed In The Machine

This issue implies that the bags are not feeding appropriately into the machine due to dirty sensors, broken air valves, or vacuum pad breakdown.

Solving this error calls for properly cleaning the proximity sensor and replacing or repairing the broken air valve and vacuum pad.

Bags Failing To Open

This error implies the equipment can never open the bags, or it opens the bags inconsistently for product filling.

Some possible causes of this issue include a worn-out filter, incorrect timing, incorrectly loaded bag, sagging bag, or vacuum pad breakdown.

Troubleshooting this error calls for correct timing, feeding the bags correctly, changing the filter, and replacing or repairing vacuum pad.

Flawed Bag Seals

This error indicates that package seals are uneven, weak, or wrinkled.

Often, it arises from different factors such as scratched or dirty sealing bar surface, incorrect sealing bar pressure, and too high sealing bar temperature.

It may also arise from failure or incorrect centering of the bag.

Some steps to solve the issue include sealing the bar surface, regulating sealing bar pressure, regulating sealing bar temperature, leveling the grippers, and centering the bag.
