Chocolate products place heavy demands on packaging machine manufacturers. The Italian company Fima specializes in the packaging of confectionery products. To make sure that the machines “stay in time” and that the individual modules are perfectly synchronized the company uses Pilz motion control.



Modular concept for packaging chocolates

Fima’s “Sweet Magic HF” wrapping machine can handle several different wrapping styles for chocolate

pralines.

All Fima machines have a modular design, so they can be broken down into individual modules including infeed, paper handling, turntable, wrapping, belt and pick and place modules.



Special configuration features

The various modules are easily accessible for rapid format change. All modules are self supporting, so dirt drops off as soon as the module is removed.

All the servo motors are linked to the movement of the turntable via electrical cams. The cams are defined via the stored recipes, and all the machine’s movements are finely coordinated in the process. All the adjustments for new products result from the recipe selection made on the operator terminal.

It’s possible to undergo a complete format or product change in around 30 minutes, including all the mechanical modifications.



High-level performance

The machine’s flexibility was achieved thanks to the versatility of the PMCprimo Drive. This enables the operator to optimize the synchronization of the individual axes at any time.

The “Sweet Magic HF” uses five Pilz servo motors, which are automated via the drive integrated control system. Optimum packaging is achieved thanks to the ability to detect the exact position of both the product and the wrapping material.

All functions are implemented using ready-made software program modules in accordance with IEC61131-3. All the digital outputs on the PMCprimo Drive can be used as digital cams. The status of the outputs depends on the respective axis position. Fast reaction times are guaranteed and the solenoid valves in the machine are reliably controlled.


Solutions for the packaging industry

Pilz combines the issues of safety, automation and motion control. Many Pilz products are designed to meet the specific needs of the packaging industry. PSEN safety switches are resistant to cleaning agents while the range of PMI operator terminals includes units with approval to be used in flammable and explosive environments.
