Mechatronics in the service of packaging

Automatic format changeover and flexibility for PFM’s D-series packaging machine: objectives achieved with the help of Siemens.

Proper mechatronic design of packaging systems is proving to be an increasingly crucial factor for success on the market.
Siemens is convinced of this, and leveraging its consolidated knowhow in the field, is offering its services as a reliable technology partner for packaging OEMs.

Sharing competencies. For example, Siemens mechatronic technology is the basis of a partnership with the PFM Group, which since 1964 has designed and built high performance packaging machinery and systems for the food and non-food sectors, setting itself apart with an unwavering commitment to research and development.
The focus of the project started jointly with Siemens was to develop the D-Series automatic packaging machine for high-speed production of standup bags (up to 360 ppm).
The primary target was to build a completely mechatronic machine with independent axes, guaranteeing quick automatic changeover and eliminating the need for manual intervention by the operator.

SINAMICS S120 E SIMOTION
Siemens initiatives to promote mechatronic technology expertise include its partnering with various Italian universities, including the Polytechnic of Milan (Piacenza campus), where the firm contributed to the curriculum of the degree program in mechanical engineering (3rd year) with a number of dedicated lectures.

Siemens fully satisfied PFM’s stated requirements by supplying a Simotion D445 multi-axis motion controller, integrated with the Sinamics S120 drive system, running Simotics 1FK7 brushless motors.
The motion control is able to manage axes with very reduced cycles and makes intensive use of the electronic cam concept (on a DX series up to 30 axes are controlled).
The IO management is performed through an ET200SP peripheral or an ET200AL in case of direct in-machine acquisition, with IP65-67 grade protection.
The partnership also proved winning in light of the proven reliability of the many installations in harsh environments and for applications requiring the use of solvents for machine sanitation.
