Patent number: 4982553Abstract: A rack, with a plurality of test tubes arranged on it, in m columns and n rows, is transported into a main housing by a rack-inlet mechanism. In the main housing, tube-extracting mechanism extracts the tubes from rack, row by row, while the rack is being transported by a rack-transporting mechanism. The tubes are then conveyed, one by one, by a tube-conveying mechanism. A plug-extracting mechanism pulls each test tube conveyed by the mechanism and the plug closing this tube, away from each other, while holding the tube and the plug, thereby extracting the plug from the test tube. The test tubes are further conveyed by the tube-conveying mechanism after the plugs have been extracted from them. The tubes are then inserted by a tube-inserting mechanism row by row, into a vacant rack transported by the rack-transporting mechanism. After a predetermined number of rows of test tubes have been inserted into this rack, a rack-outlet mechanism transports the rack from said main housing.Type: GrantFiled: November 30, 1987Date of Patent: January 8, 1991Inventor: Teruaki Itoh
