GREIF - on-the-fly barrel control

For a barrel packaging line, Greif Italy needed a dynamic system for controlling barrel weight in comparison with a standard weight.
The weighing system had to meet the following performance standards: a weighing rate of 100 barrels per minute, with a deviation of less than 10 grammes for a weighing capacity of 25 kg.

SCAIME offered a solution with its Italian integrator partner NONIS Srl.

In this solution, the PLC controls the conveyor belt. With the parameters provided by the PLC or the eNodTouch man-machine interface, the eNod4-C oversees digital filtering, calculation of the weight of each barrel, and automatic elimination of non-compliant products.

• This architecture enables simple and very fast control of products at the end of the production line: each product is controlled and incomplete tanks are automatically eliminated by the eNod4-C.
• The system can be used to achieve very high rates, controlling up to 120 tanks per minute, at the required precision of plus or minus 5g.
