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. |
