Lantmännen Unibake produces and delivers frozen bread all over the world. The bakery in Hatting near Horsens faced challenges with a production machine where much of the technology was outdated, leading to more waste and few opportunities for efficiency improvements. They struggled with the old machine, which could not run faster and had complex troubleshooting. 

The new approach to controlling the machine's movements was secured with the help of synchronizing the movement with a CAM. This way, the strong mechanics of the old machine could be retained and instead optimize the machine by installing more advanced technology than before. Now the guillotines and spreader arms run in smooth movements. It is a huge step forward from something that stutters and jumps to something that dances. At the same time, the arms now position the rolls very precisely, which is very important regarding the packing further down the belt. With the new solution they have increased speed and production by more than 10%. Similarly, start-up time is significantly reduced because many of the parameters and settings in the old machine have been made redundant - and therefore, they avoid a large part of the manual adjustment of the machine. 75% of the parameters were removed in the setup, and as there were high demands for a short start-up time, a test in the Siemens simulation tool SIMIT was made. The machine had the planned start-up and has now been in operation for a year without any problems. Strong solution based on standard components from Siemens: SIMATIC T-CPU, SINAMICS S210 servo drive, SIMATIC HMI (Human Machine Interface) panels - plus WinCC Unified software for user interface programming and SIMIT simulation software to prepare for implementation.

When renovating and improving energy efficiency at the leading manufacturer and supplier of frozen bread - Lantmännen Unibake, they think green and focus on reusing and upgrading existing production machinery. In collaboration with CesTek and Siemens, they have achieved over 10% higher efficiency, reduced waste, and reduced wear and tear on crucial production machinery. The solution was achieved by synchronizing the movement with a CAM and testing it in SIMIT simulation software to implement the new dancing movements in the production line.
