摘要： A transport system including a curved conveyance section configured for moving articles along a curved conveyance path. At least one turnstile wheel is configured to guide the articles along the curved conveyance path. In some embodiments, the turnstile wheel comprises a first surface configured to guide an exterior vertical belt along a continuous curve on an exterior edge of the curved conveyance path and a second surface configured to guide an interior vertical belt along a continuous curve on an interior edge of the curved conveyance path. The first surface and the second surface are configured to have a common axis of rotation outside the curved conveyance path and to rotate at a same angular velocity. The interior vertical belt and the exterior vertical belt are configured to support the articles as the articles are conveyed along the curved conveyance path. The articles are conveyed along the curved conveyance path without stopping or significantly slowing down. The articles conveyed may include semiconductor wafers or substrates for the manufacture of display devices.

摘要： A transport system includes a curved conveyance section configured to move an article along a curved path without significantly slowing or stopping. Exemplary articles for conveyance include semiconductor wafers and substrates for display devices and photovoltaic devices. In some embodiments, the conveyance section includes a turnstile wheel including an interior surface and an exterior surface. The external surface is configured to guide an exterior belt that in turn supports one side of the article around the conveyance path. The internal surface is configured to either support an opposing side of the article, or guide an interior belt that in turn supports the article around the conveyance path. Instead of employing a turnstile wheel, other embodiments employ interior and exterior supports for supporting opposite ends of the article, such as interior and exterior belts, that move at essentially the same angular rate along the inside and outside of the conveyance path.
