High-precision air dancer unit: ADU-AS Series Patent No. 6479588
A unit designed to significantly reduce tension fluctuations in roll-to-roll transport and achieve a higher level of transport accuracy.
Features
１.Significantly Reduces Tension Fluctuations and Enables Ultra-High-Precision Transport
Improvements have been made to conventional dancer mechanisms, realizing tension fluctuation suppression technology for ultra-high-precision transport.
- Horizontal linear-motion design eliminates the influence of gravity
- Air bearings are used in the moving section to eliminate friction resistance
- A servo valve integrated into the actuator reduces delays caused by air transmission resistance
- High-response, high-precision control is achieved through high-accuracy pressure and position sensors
With ADU-250-AS tension control, tension fluctuations can be reduced to less than half those of load-cell control or conventional dancer control.
(Transport Conditions) Material: PET film 25µm, Width: 200mm, Set Tension: 5N, Transport Speed: 5m/min
- (a)Load Cell Control
- (b)Dancer Control - Conventional Dancer
- (c)Dancer Control - ADU-250-AS
２.Stable Transport Even Under Low-Tension Conditions
When tension fluctuations during transport at an extremely low tension setting of 1N are compared between a conventional dancer and the ADU-250-AS, the ADU-250-AS reduces tension fluctuations to less than 75% of those of a conventional dancer, enabling stable transport.
(Transport Conditions) Material: PET film 25µm, Width: 200mm, Set Tension: 1N, Transport Speed: 5m/min
- Conventional Dancer
- ADU-250-AS
３.Stable Transport Even at High Speeds
In a conventional dancer system, tension fluctuations become larger as the transport speed increases. However, with the ADU-1200-AS, there is almost no change in tension fluctuations caused by changes in transport speed. Stable transport can be achieved with consistent tension even during high-speed operation.
(Transport Conditions) Material: OPP film 20µm, Width: 1000mm, Set Tension: 10-50N, Transport Speed: 5-200m/min
