Description

Greif is a world leader in industrial packaging products and services. They produce steel, plastic or fibre containers and provide blending, filling and packaging services for a wide range of industries.

Customer need

GREIF Italia needed to dynamically control the weight of containers, by comparison with a standard weight. The weighing system had to achieve the following performances:

  • Weighing rate of 100 product / min. with standard deviation <10g for product weight up to 25kg

SCAIME solution

SCAIME provided a solution in partnership with its Italian integrator NONIS Srl. In this solution, the PLC takes care of general system controlling.

With the parameters coming from the PLC or eNodTouch, eNod4-C takes in charge digital filtering, dynamic checkweighing functions and automatic ejection of non-compliant products.

SCAIME products:

  • 4 load cells F60X 50kg with STABIFLEX mounting kits
  • 1 Checkweighing controller eNod4-C on Profibus-DP
  • 1 tactile HMI eNodTouch

Automation products:

  • 1 PLC SIEMENS
  • Conveyor belt

Customer benefits

  • This architecture provides high speed in line production monitoring: Each product is controlled and incomplete containers are automatically ejected by eNod4.
  • The system reaches very high speed, by controlling up to 120 containers / min, at the requested accuracy of +/-5 g.
