2. Description of the Related Art In a sample pretreatment system for dispensing a sample from a parent sample container to a child sample container, various data necessary for sample pretreatment are registered before the system is started. For example, along with the designation of the dispensing mode, the arrangement of the child sample containers, the selection of the parent sample container, the dispensing items, etc. are registered. Since the sample pretreatment system uses a plurality of child sample racks in which a plurality of child sample containers are aligned, the registration of the array of child sample containers is performed as the registration of the data of each child sample rack. Then, the sample pretreatment system advances the sample pretreatment based on these data. On the other hand, the progress status of these processes is sequentially displayed in characters on the display screen. Then, when the predetermined dispensing is completed, the operator sees the contents of the display screen, removes the slave sample rack for which the dispensing has been completed, and sets the necessary slave sample rack when continuing the dispensing. .

[0003]

A large number of sub-sample racks are arranged on the dispensing table, the number of which is
For example, when the number is small, the number is 4, and when the number is large, the number is 20.
Moreover, the timing of replacement varies depending on each child sample rack. In such a situation, the operator must definitely remove the sub-sample rack that has been dispensed, and newly set the sub-sample rack of the target item for continuing the dispensing. Therefore, it is difficult to determine a child sample rack to be removed from a large number of child sample racks only by displaying the contents such as characters on the display screen.

[0004] It should be noted that although a child sample rack with a color is sometimes used, it is only used aimlessly to distinguish it from others, and means for utilizing that color when replacing the rack. There was no

An object of the present invention is to solve the problems of the prior art and to provide a sample pretreatment system which facilitates the discrimination of each child sample rack displayed on the display screen.

[0006]

In order to achieve the above object, a sample pretreatment system according to the present invention is arranged on a dispensing nozzle and a dispensing table for dispensing a sample, and the sample is accommodated therein.

The dispensing sequence is performed as follows under the control of the control processing unit 304. First, it begins with the nozzle tip not attached to the nozzle base. By the operation of the nozzle transport mechanism 40, the nozzle base is moved in the horizontal direction, and the position of the nozzle base is moved right above the chip rack 52. Then, the nozzle base is lowered toward the tip head opening of one unused nozzle tip 58 in the unused nozzle tip group. This pushes the nozzle base into the tip head opening of the unused nozzle tip 58,
The nozzle is formed. After that, nozzle 50 up to a predetermined height
Is moved up, the nozzle 50 is moved in the horizontal direction, and the position of the nozzle 50 is moved right above the parent sample container to be dispensed at the dispensing position 38. In this way, preparation for dispensing is made.

Next, the nozzle 50 is lowered, and a predetermined amount of the parent sample is sucked into the nozzle tip by drive control of the dispensing pump. The predetermined amount is the total amount of the three sub-samples when subdivided into, for example, three sub-sample containers.

Next, the nozzle 50 is raised to a predetermined height while holding a predetermined amount of the parent sample in the nozzle tip,
The position of the nozzle 50 is moved right above the sub-sample container to be dispensed.
The sub-sample container of the dispensing destination is the normal sub-sample container held in the normal sub-sample rack 56 in the normal dispensing mode, and the emergency sub-sample rack 77 in the emergency area 76 in the emergency dispensing mode. It is the retained emergency child sample container 79, and the control processing unit 304 instructs the dispensing destination. Then, the nozzle 50 is lowered at the position of the sub-sample container of the dispensing destination, and a predetermined amount of the sucked parent sample is discharged by drive control of the dispensing pump. Thereafter, this sequence is repeated, and the parent sample is dispensed from one parent sample container to a predetermined number of child sample containers.

When the dispensing of one parent sample container is completed, the nozzle 50 is moved in the horizontal direction, and the position of the nozzle 50 is moved right above the chip remover 54. Then, the nozzle 50 is lowered, the used nozzle tip is hooked on the tip remover 54, and then the nozzle 50 is raised to a predetermined height. As a result, the used nozzle tip is removed from the nozzle base and drops into the tip waste container arranged directly below the tip remover 54. Thereafter, as described above, the unused nozzle tip is replaced with the nozzle base portion, and the dispensing from the next parent sample container is repeated by repeating the same sequence.

When a predetermined dispensing is carried out for all the parent sample containers arranged in one parent sample rack, the parent sample rack is transported along the transport path and sent to the discharging section 62 for automatic or manual operation. It is carried out by work.

Next, the container carrying device 18 will be described. The container transport device 18 is a mechanism that freely transports the container held by the manipulator in the three axial directions of the X axis, the Y axis, and the Z axis. The container transfer device 18 includes two second guide rails 42 arranged in the X-axis direction which are also used in the nozzle transfer mechanism, a second base 66 movable on the second guide rail 42 in the X-axis direction, and a second base 66. A second Y-axis arm 68 extending in the Y-axis direction integrally with the 2 base 66, and a second Y-axis arm 68.
And a manipulator base 70 that is movable in the X-axis direction along the
Will be installed. The manipulator 72 is movable in the Z-axis direction with respect to the manipulator base 70.

The second guide rail 42 is used for the container transport device 1.
8 and the nozzle transport mechanism 40 are used in common, the moving area of the manipulator 72 is a wide range up to the parent sample rack at the dispensing position. Therefore, by using the operation of the manipulator 72, the container can be transported to the abnormal parent sample retreat area 74, the emergency area 76, and the labeling device 19 provided within the range of the movement area.

The abnormal parent sample retreat area 74 is an area for accommodating a parent sample container recognized as an abnormal parent sample. When it is recognized as an abnormal parent sample, for example, the label reading position 2
In addition to the case where there is an error in the confirmation of the presence or absence of the container and the reading of the label in 6, it is possible to include an opening mistake, a dispensing mistake and the like. The parent sample container recognized as the abnormal parent sample is once sent to the dispensing position 38. Then, according to the instruction of the control processing unit 304, the manipulator 72 is moved to a position right above the abnormal parent sample container at the dispensing position 38 by the operation of the container transport device 18, and descends to hold the abnormal parent sample container. It rises to the height and moves directly above the abnormal parent sample retreat area 74.
Then, the abnormal parent sample rack 75 in the abnormal parent sample evacuation area 74 is lowered at a predetermined container storage location, the holding is released, and the abnormal parent sample container is stored.

In addition, the emergency child sample rack 77 is installed in the emergency area 76 as described above. However, there is a case where the emergency child sample rack 77 does not initially hold the child sample container. In that case, under the control of the control processing unit 304, the manipulator 72 causes the normal child sample rack 56 to operate.
The unused normal child sample container is held from and is transported to the labeling device 19 as the emergency child sample container 79. Then, after the label sticking device 19 sticks a predetermined label, the manipulator 72 again transfers the label-applied emergency child sample container 79 from the label sticking device 19 to the emergency child sample rack 77. In this way, using the operation of the manipulator 72,
The unused normal child sample container can be transferred from the normal child sample rack 56 to the emergency child sample rack 77 as the emergency child sample container 79.

In addition to this, for example, the emergency parent sample container is usually dispensed to the child sample container of the dispensing destination in the child sample rack 56, and the child sample container after the dispensing is replaced with the emergency child sample container 79. Alternatively, the manipulator 72 can be used to transfer the normal child sample rack 56 to the emergency child sample rack 77.

Next, the label sticking device 19 will be described. The label sticking device 19 includes a label sticker 80 and a holder 82, and cooperates with the transfer mechanism 84 to convey the sub-sample container. The label applicator 80 prepares a predetermined label to be attached to the child sample container, and attaches the label to the child sample container received by the holder 82. In the label sticking process, the data of the parent sample container acquired at the label reading position 26 can be transferred and processed in parallel with the dispensing.

As described above, the sample pretreatment unit 302 repeats the above series of flow under the control of the process control unit 320, whereby the parent sample can be dispensed and the label can be attached efficiently. . The processing status such as the dispensing progress status in the sample preprocessing unit 302 is transmitted to the sequential control processing unit 304 via the communication control unit 308, and the dispensing status management unit 322 manages the progress status. Then, the image forming unit 326
The management table of the registration data stored in the storage device 314 is referred to, the dispensing status at each moment is associated with the sub-sample rack, and a status display image is formed and displayed on the display 312. In the following description, unless otherwise specified, the child sample container usually means a child sample container, and the child sample rack usually means a child sample rack.
