This project involved the creation of an automatic filling, capping, weighing and labelling line for a customer who packages aggressive liquid products for the medical sector.
Specifically, the system was designed to perform the entire packaging cycle in two bottle formats with a single cap and a capacity of 750 ml and 1 litre (photo 1).

The line consists of: (photo 2)
– Container feeding table at the start of the line
– Dosing monoblock with two peristaltic pumps and automatic cap positioning and screwing system
– Checkweigher integrated into the system with automatic rejection system
– Labelling machine for front and back labelling
– Container accumulation table at the end of the line

The dosing station is equipped with peristaltic pumps and a pulsation damper, a system designed to treat the customer’s products with maximum efficiency and cleanliness. These products are aggressive and cannot come into contact with metals.
The two pumps are positioned under the rotating loading table (photo 3) and are connected to the dispensing nozzles by flexible hoses that are easily removable for cleaning operations. They are equipped with a pulsation damping system and suitable magnetic flow meters for measuring the quantity of product to be dispensed.

The monoblock connects at the outlet via motorised vertical belts to a checkweigher (photo 4) which detects and certifies the correct weight of each bottle within the pre-set ranges, and then to an automatic labelling station.
If a non-compliant weight is detected, an automatic bottle rejection system is activated before the label is applied.

All processing data from the plant is integrated into the customer’s management software through a bidirectional communication system between the software programs, which allows for the archiving of production data, cycle times, any rejects, etc.
Finally, the line was designed with an angular structure to allow for its adaptation within the customer’s production workshop.
