Rotary QS
The Rotary QS
element is another building block of the ERECT-A-LINE® family of
conveyors. Its CLEAN-DRIVE® version is intended for clean room
manufacturing environments.
Inserting a QS
element in a network of Linear Drives provides for the switching of the
transport FOUPs, or carriers from one Linear Drive to another. The Rotary QS element rotates the FOUP or
carrier as it switches it such that the leading edge will remain the same when
transferred onto the next Linear Drive.
The Rotary QS right angle rotation in combination with the
bi-directional drives provides four possible switching directions for the
pallet.
The Rotary QS
element is essentially a short rotating section of the Linear Drive. This short section is rotated using the same
hysteresis drive mechanism that conveys pallets, cassettes or FOUPS. The Rotary QS element is likewise equipped
with the same hard or SOFT BUFFERING® system as the linear drive
sections. A FOUP is stopped after
entering the QS Rotary element, and continues on after the switching operation
is complete.
