    • A system and method for conveying and for accurately handling a generally flat object employing a plurality of support elements. The system comprises: a plurality of vacuum preload drive wheels arranged in one or more drive units, each drive unit comprising at least one vacuum preload drive wheel; one or more vacuum ports located on one or more counter plates adjacent each of the vacuum preload drive wheels, for applying induced holding down forces on the object. The vacuum ports of each drive unit are fluidically connected to a main vacuum pipe with controllable valve to a vacuum source. When the main vacuum pipe is connected to a vacuum source the normal force between the object and the vacuum preload drive wheels is increased and accordingly the lateral drive force is increased.
    • 一种用于输送并准确地处理采用多个支撑元件的大致扁平物体的系统和方法。 该系统包括:布置在一个或多个驱动单元中的多个真空预载驱动轮,每个驱动单元包括至少一个真空预载驱动轮; 位于与每个真空预载驱动轮相邻的一个或多个计数器板上的一个或多个真空端口,用于在物体上施加诱发的保持力。 每个驱动单元的真空端口与具有可控阀的主真空管流体连接到真空源。 当主真空管连接到真空源时,物体和真空预载驱动轮之间的法向力增加,因此横向驱动力增加。

    • An apparatus for supporting a stationary or moving substantially flat object without physical contact on an fluid-cushion. The object floats on a fluid cushion gap, the apparatus aimed for globally or locally adjusting the gap. The apparatus comprising: a first platform for supporting the object without contact, the platform having a substantially flat active surface comprised of one or more sectors, each sector comprising at least one of a plurality of basic cells, each basic cell having at least one of a plurality of pressure outlets fluidically connected through a pressure flow restrictors to a higher-pressure manifold associated with the sector in which the basic cell lies, the higher-pressure manifold is fluidically connected through main supply pipeline to pressurized fluid supply and at least one of a plurality of fluid-evacuation channels fluidically connected to a lower-pressure manifold associated with the sector in which the basic cell lies having main evacuation pipeline; wherein the flow restrictor characteristically exhibiting fluidic return spring behavior; and wherein at least one pressure control valve is interposed with at least one of the two main pipelines of at least one sector for controlling pressure levels of at least one of the two manifolds of that sector.
    • 一种用于支撑静止或移动的基本平坦的物体而不在液垫上物理接触的装置。 物体漂浮在液体缓冲间隙上,该装置旨在全局或局部调整间隙。 该装置包括:用于在不接触的情况下支撑物体的第一平台,所述平台具有由一个或多个扇区组成的基本上平坦的有源表面,每个扇区包括多个基本单元中的至少一个,每个基本单元具有至少一个 多个压力出口,其通过压力限流器流体连接到与基本单元所在的扇区相关联的高压歧管,高压歧管通过主供应管线流体连接到加压流体供应器,并且至少一个 流体连接到与基本单元所在的具有主排空管线的扇区相关联的低压歧管的多个流体排出通道; 其中所述限流器特征性地表现出流体回流弹簧的性能; 并且其中至少一个压力控制阀插入有至少一个扇区的两个主管线中的至少一个,用于控制该扇区的两个歧管中的至少一个歧管的压力水平。
