| 20090175692 | PNEUMATIC CONVEYOR SYSTEM - A pneumatic conveyor system includes an air blower for supplying an air source, a central control system, a transmission tube, and a transmission terminal installed at the transmission tube. The transmission terminal includes a tubular groove connected with the transmission tube and having a tubular cavity wall surface, above which is a micro-movement sensitive switch and a photoelectric sensor. The system further includes a transmission carrier having a hollow cylindrical axial extension of the body of the carrier and is placed within the cavity of the tubular groove. One of the transmission ends is closed and the other end has an opening, and the opening is built to be closed by a transmission carrier cover. The cover is disposed a ring capable of triggering the micro-movement sensitive switch. When a movement of placing the transmission carrier into the tubular groove triggers the micro-movement sensitive switch and the photoelectric sensor, the air source from the air blower is initiated onto the transmission carrier to push the transmission carrier inside the transmission tube. | 07-09-2009 |
