Powder Mixing with Wireless PROFINET – Productivity Has Tripled
The Dutch powder mix provider Huijbregts Groep used the features of 96 VLT® AutomationDrives for a redesigned and highly automated mixing facility in Holland. This tripled the productivity, improved the quality 200 % and made work easier and safer for the employees.
Mixing the powders used to take place in manually loaded mixers, which involved moving the individual powders to the mixer and the finished, mixed, powders to a packaging area.
The new design has 24 mobile mixers of 1500 kg max. capacity running on a common power rail mounted on the factory ceiling. Every mixer has an IP66 7.5 kW VLT® AutomationDrive on board, each connected to a PLC through wireless PROFINET.
Extra Power Supply
The IP66 housing allows mounting of an extra power supply for the wireless client that is also mounted on every mixer.
Positioning via Smart Logic Controller
Positioning of each mixer is handled by the VLT® Smart Logic Controller as they are moved around on automatic wagons, also connected to a PLC via wireless PROFINET. The wagons are also powered from the common rail in the ceiling.
Software to Control Logistics
A specially developed software system controls the wagons and the mixers are automatically placed at their correct filling stations, where each is filled automatically.
When filled, it runs automatically towards the packaging department, connects itself and empties the ready mixed powder into the packaging machine. Emptied, the mixer is automatically moved to a dry or wet cleaning facility and waits for its next task.
