The Vertical Form Fill and Seal Bagging Machine (VFFS) offered by Kockums Bulk Systems is a fully automated device forming bags from a roll of flat film. The machine is well known in the packaging industry specifically where granular or dusty products are packed.
A typical installation will include a product infeed system, bag flattener with/without turning and an out feed conveyor. When mated with an automatic palletiser and pallet hooding machine, the installation becomes a high speed production line capable of delivering up to 60 bags/minute.
The FFS activity is initiated by first loading a roll of flat film on the back of the filling unit. The film is then fed through a sequence of roller tubes and finally wrapped around a forming tube into the shape of a bag of which the bottom end and back is then heat sealed. At the same time, the product is measured by volume or weight and then fed to the inside of the forming tube around which the bag is formed. With the exact amount of product in the bag, the bag is fed off the forming tube, the top heat sealed and the sealed bag is dropped onto the outfeed conveyor.
The device can fill 16 - 60 bags/minute depending on the size. A range of filling chutes are available to suit various size bags. Cleaning and maintenance of the machine is made easy as it has few moving parts. The machine is fully guarded in agreement with the Australian safety standards.
