Let the machine tune itself for minimum air consumption/power
The ARVD II Plus automatically adapts the opening and closing time of the relay nozzle valves according to the behavior and air-friendliness of the filling yarn.
Energy costs directly affect the profitability of weaving mills and therefore require specific attention when designing production equipment such as weaving machines.
Picanol invests a lot in optimizing the air consumption of its looms so that customers can use the available energy as efficiently as possible. One of the many developments for this is the Automatic Relay Valve Drive or ARVD II Plus.
The ARVD II Plus automatically adapts the opening and closing time of the relay nozzle valves according to the behavior and air-friendliness of the filling yarn. Customers can select one of three levels of automatic adjustment – low, medium or high – to suit the type of filling yarn. Each level indicates how much the relay nozzle blowing times can be adjusted by the machine. Optimization of the opening and closing times can also be enabled individually.
When activated from the machine's BlueTouch display, ARVD II Plus continuously monitors the main insertion parameters measured by the machine, such as the winding timings and filling arrival time. These data are processed and evaluated and the valve blowing timings of the relay nozzle valves are adapted automatically. The system reduces blowing times until it detects a potentially unstable situation and then reverts to the optimal situation.
ARVD II Plus has been tested and proved effectively in the field on a broad range of yarns and gives optimal results with both spun and filament yarns.
With the more stable insertion on all Picanol airjet machines, the ARVD II Plus can even achieve higher savings!
