FLUID TRANSPORT APPARATUS FOR STOPPING AND RETURNING CAPSULE CONTAINING SAMPLE THEREIN AT WORK POSITION IN PNEUMATIC CARRIER

摘要

PURPOSE:To stop a capsule correctly without a shock and return the capsule by boring a connecting hole and a discharge hole through a work position so that a fluid is forced to flow into a pneumatic carrier through the connecting hole and the fluid is discharged through the discharge hole to balance fluid pressure. CONSTITUTION:A capsule 6 is fed to a work head 2 by compressed air in a pneumatic carrier 3, and at the same time, compressed air is fed into the work head 2 through a fluid conduit pipe 14 to flow into the pneumatic carrier 3 through each circulating hole 12, so that the capsule 6 is fed by pressure in the pneumatic carrier 3 and stopped at a position corresponding to a discharge hole 13 where the pressure of the compressed air fed from the opposite direction is balanced. Subsequently, compressed air is continued to flow from an analysis chamber 4, and solenoid valves 16, 22 are closed to exhaust the compressed air in the work head 2 quantitatively through an exhaust valve 17, so that the capsule 6 is lowered in the pneumatic carrier 3 at uniform speed and brought into pressure contact with a table seat 26 to be stopped.
