Abstract

PURPOSE:To accurately stop the rotor of a centrifugal separator at a position for taking a rack in and out for eliminating failure in the operation of taking said rack in and out, by stopping the motion of an indexing mechanism when a signal for a stop position is outputted from a detector for the stop position. CONSTITUTION:A rack 12 holding a plurality of centrifugal pipes 11 which receive a sampled body to be examined is attached to the rotor 4a of a centrifugal separator 4, the boty to be examined being existent in the centrifugal pipes 11 is centrifugally separated by the rotation of said rotor 4a, and the rack 12 is detached from the rotor 4a after the centrifugal separation. In the automatic centrifugal dispenser equipped with an indexing mechanism 25 for checking the stop position of the rotor 4a when the rack 12 is taken in or out of the centrifugal separator 4 in this way, the central processing unit 20 of a microcomputer still drives the mechanism 25 even when the rotor 4a stops at its stop position, and stops the motion of the mechanism 25 when a signal for the stop position is outputted from a detector 24 for the stop position again to accurately stop the rotor 4a at a position for taking the rack 12 in or out.

FIG. 3 is a flowchart showing an example of a program for processing when loading/unloading a rack in the CPU 20 of FIG. 2. When the rotor 4a is stopped after the start of centrifugation or the end of centrifugation, the stop F position detection circuit 2 is activated in step S1.
4, check whether there is a stop position detection signal or not. If there is a signal, step S2 causes the ingen 4 and mechanism 25 to start indexing operation, and after a slight time delay in step S3, stops again + I = position detection. It is determined in step S4 whether there is a signal, and if there is no signal in step S1, the indexing operation is started in step s5 as described above, and in step S4 it is determined whether or not there is a stop upper position detection signal,
When the stop upper position detection signal is input manually from the stop F position detection circuit 24 in step S4, the indexing operation is completely stopped F in step S6, and the loading and unloading work of the rack 12 is started in step S7. Note that if there is no signal at step s4, the driver waits at the intersection where there is a signal.

In this way, when the rotor 4a stops, the indexing mechanism 25, which is required regardless of the presence or absence of the stop F position detection signal,
is operated to rotate the rotor 4a at a slow speed, and when there is a stop F position detection signal, the stop position signal is output again when the stop position detection signal is output.If there is no signal, the stop F position is detected by Intex operation. Since the INTEX operation is stopped when the signal is output and the rack 12 is then moved in and out, the rotor 4a can be stopped at the stop F position accurately and reproducibly, and the rack 12 can be moved in and out. It is possible to prevent failures from occurring.

When I first started the Intera winter operation when the rotor 4a was at the stop position, I was instructed to check for the presence of the stop position signal after a certain period of time.
This is to wait until the first stop position signal disappears and then check for the presence of a subsequent stop position signal.
The reason why the indexing operation is started even when the rotor 4a is initially at the stop position is that when the rotor 4a stops from high speed and the stop upper position signal is output, the stop position signal is Even if the output is low, the rotor 4a
This is because there are many cases where the motor does not stop at the correct upper stop position.

As described above, according to the present invention, it is possible to improve the rotor stop position signal, and there is an effect that failures in loading and unloading the rack can be eliminated.
