A CENTRAL TRIM EXTRACTION SYSTEM FOR TEA PACKING MACHINES MINIMISES DOWNTIME AND DUST PROBLEMS
Kongskilde
Trim from Tea Packing Machines
Kongskilde delivers a trim extraction system allowing production machines to run at maximum speed without the need to worry about clogging from extracted trim.
A factory located in Poland is a well-known tea producer for the domestic and international markets
The client has two machines with the ability to extract bags, and six machines where the cutting and handling of trimmings take place
The small diameters of the exhaust pipes on the machines are due to the need to overcome high pressure in the system
Before the system was in place, it was necessary to extract trimmings through local exhausts, causing a need for additional employees
Local exhausts were causing numerous downtimes and messes during the production process, and were taking up room in the production hall
The company needed a solution for the extraction of trimmings in order to ensure cleanliness in the production area and increase productivity while keeping downtime, and the number of personnel members operating production equipment, to a minimum
The Facts
Machine nos 1-2
Material: Paper (tissue), plastic film
Dimensions: 120 x 120 mm
Material weight: 21 g/m2
Quantity: 150/min.
Machine nos 3-8
Material: Paper – continuous cutting and extraction
Trim width: 12 mm
Material weight: 21 g/m2
Speed: 17.5 m/min.
The Solution
The system includes dust suction points with pressure sensors
The installation was divided into three separate lines where the lift force is generated by BTK fans
All dust is separated from the transported air by the bag filter (KNFK) and discharged to a large bag with a dust-level indicator
All of this is controlled by an intuitive control device
The Advantages and Benefits
Kongskilde’s solution collects inline waste – there is no longer need to stop production for cleaning
The risk of accidents has been significantly reduced
Equipment failures are minimised
Downtime of control equipment has been reduced
The return of air from the filter has lowered heating costs
Dust collection significantly facilitates logistics, and allows it to be further processed or resold
