Automated sample testing system
View Patent ↗An empty rack transport line is arranged at a lower stage and independent of a main transport line, a fast emergency line and a reverse line. In a rack stocker, an inclined transport line connects the empty rack transport line to the rack stocker. The rack stocker is arranged between a storage module and a loading module. The rack stocker is capable of continuously supplying and collecting empty racks, while transport lines do not cross each other. It is, therefore, possible to continuously supply and collect empty racks in a simple configuration, without an increase in the system size, an intersection of transport lines and a reduction in processing capability. In addition, it is possible to provide an automated sample testing system that is highly extendable for various facility sizes.
1. An automated sample testing system comprising: a main transport line for transporting a sample rack holding at least one sample; a plurality of processing units that are arranged along the main transport line; an empty rack transport line for transporting an empty sample rack and which extends in parallel to the main transport line; a straight inclined collection line for transporting the empty sample rack from the main transport line to the empty rack transport line; a straight inclined supply line for transporting the empty sample rack from the empty rack transport line to the main transport line; a first transport line for transporting the empty sample rack from the main transport line to the straight inclined collection line and connected therewith; and a second transport line for transporting the empty sample rack from the straight inclined supply line to the main transport line and connected therewith, wherein the empty rack transport line is arranged at a lower stage than the main transport line.
2. The automated sample testing system according to claim 1 , wherein the empty rack transport line is a dedicated line that is independent of the main transport line, and wherein the empty rack transport line includes a forward line and a reverse line which extend in parallel to each other.
3. The automated sample testing system according to claim 1 , further comprising: a main transport line for transporting a sample rack holding at least one sample; a first sample processing unit that is arranged along the main transport line; a rack stocker that is arranged along the main transport line and includes the straight inclined collection line and the straight inclined supply line; a loading module that is arranged along the main transport line and loads the sample onto the main transport line; and a storage module that is arranged along the main transport line and stores the sample which has completed processing, wherein one of the processing units, the storage module, the rack stocker, the loading module and another of the processing units are arranged in this order so that the storage module is adjacent to the one of the processing units and the rack stocker, and the loading module is adjacent to the rack stocker and the another of the processing units.
4. The automated sample testing system according to claim 1 , wherein the first transport line, the second transport line, the straight inclined collection line and the straight inclined supply line are perpendicular to the main transport line.
