Automation

_

In SMI stretch-blow moulders, designed according to INDUSTRY 4.0 parameters, fully automatic processes, electronically-controlled operations and wiring by field bus are synonyms of reliability, considerable operational flexibility and high performance. Hardware and software components are IoT (Internet of Things) ready, are “open“ and modular, comply with the most important international certifications and rely upon consolidated standards of the industrial field and of the packaging sector: OMAC guidelines (Open Modular Architecture Controls), sercos, PROFIBUS, IEC61131, OPC, Industrial PC.

In particular, by following the OMAC guidelines and the Omac Packaging Workgroup (OPW), SMI can guarantee easy integration with the other machines in line, user friendly technology and maintenance of the investment value. The automation and control system of SMI machines, called MotorNet System®, includes the following hardware components: MARTS (process controller), POSYC (manmachine interface), COSMOS (digital servodriver for brushless motors), dGATE and aGATE (remote IP65 I/O digital/analogic modules).

The MARTS is a PAC (Programmable Automation Controller), based on an industrial PC, which can be programmed in IEC61131 languages. The COSMOS servodrivers and the dGATE/aGATE I/O modules are connected to the PAC via sercos. The POSYC is a HMI terminal, (touch screen IP65), based on an industrial PC with solid state drives.

SMI stretch blow-molders are very easy to use; in fact, thanks to the MotorNet System® technology, it is possible:

  • To set the heating profile for each preform and the parameters influencing the phases of the stretch-blowing process (from when the preform enters the heating module up to the container)
  • To adjust the power of each lamp in each section of the heating module
  • To control the operation parameters of each stretch-blowing station and monitor the whole stretch-blowing process in real time
  • To store the parameters of each blown container
  • To check and set the machine production speed, according to the different types of containers
  • To carry out the changeover in a quick and easy way
  • To solve or prevent any problems, thanks to the teleservice, the graphic alarms displayed on the POSYC and the signal of the maintenance interventions to be carried out
  • To have access to the on-line manuals on the POSYC
  • To ensure high outputs, excellent quality levels and very low noise
  • To monitor the performance and analyse the down-times (Pareto diagram)
  • To interchange the POSYC with compatible Panel PC (SIEMENS, ALLEN BRADLEY)
  • To interchange the COSMOS with compatible sercos pack profile servodrivers.
