A sensor unit for detecting an empty sample rack, a sample rack supply unit for supplying an empty sample rack, a robot having a hand mechanism for gripping a sample container, and a controller for controlling at least the operation of the robot. To determine whether or not the sample is a sample rack containing a non-standard sample that does not satisfy the conditions.If it is determined that a non-standard sample is stored, the condition is determined from the sample rack. It is characterized in that all the samples within the standard that satisfy the condition are gripped, and the gripped sample within the standard is transferred to an empty sample rack supplied from the sample rack supply unit. .

The controller preferably includes a sample information storage unit that stores the storage position information of the sample container in the sample rack and the detection result information by the sensor unit in association with each other.
In addition, the controller has a second robot having a hand mechanism for gripping the sample container, and the controller controls the second robot based on the information stored in the sample information storage unit and preset destination master information. It is preferable to move each of the in-spec samples stored in the sample rack to the set carry-out position.

In addition, a first unloading unit for unloading sample racks containing non-standard samples, a second unloading unit for unloading sample racks containing only non-standard samples, and a sample rack from which non-standard samples have been removed by a robot are transported. It is preferable to have a first derivation mechanism for unloading from the line to the first unloading section, and a second derivation mechanism for guiding a sample rack storing only samples within the standard to the second unloading section.
When the number of sample racks stored in the second carry-out unit reaches a preset number, a bundling mechanism that binds the sample racks stored in the second carry-out unit, and a sample that stores the sample rack bundle bundled by the bundling mechanism It is preferable that the controller operates the robot to grip the sample rack bundle bound by the binding mechanism and transfer it to the sample rack bundle storage unit.

The hand mechanism includes a sample container gripping mechanism that is half the number of sample containers that can be stored in the sample rack, and each sample container gripping mechanism corresponds to two opening centers of each storage section of the sample rack. It is preferable that they are arranged at intervals.
The hand mechanism preferably has a rack bundle gripping mechanism for gripping the sample rack bundle separately from the sample container gripping mechanism.
Further, the sample rack has an opening for storing the sample container, and the sample rack is preferably placed in a state inclined by a preset inclination angle with respect to the horizontal plane.

  According to the present invention, the sample container can be sorted more reliably and accurately because the sample within the standard suitable for gripping by the robot is transferred based on the detection result by the sensor unit without using the robot. The specimen inspection work can be automated efficiently.

If the sample container has a shape other than the standard size, it cannot be accurately grasped by the operation of the robot 101A. It is for fear.
Condition 2 is for removing a sample container or the like that should not exist in the original process.
Condition 3 is for removing such a sample container because there is a possibility that the accuracy of the gripping operation or the like by the robot 101A may be reduced if the deposit adheres to the sample container W.
In condition 4, as in condition 3, if the lid of the sample container W is determined not to be normally attached, the accuracy of the gripping operation or the like by the robot 101A may be reduced, so such a sample container is removed. Is for.
Condition 5 is that there is a possibility that the test cannot be performed because the liquid volume of the sample is less than the minimum amount required for the test, or that the agitation cannot be reliably performed because the liquid volume of the sample is too large. It is intended to remove a specimen that has a problem and a specimen that cannot be accurately measured because the specimen itself is coagulated.

  In addition, a sample that satisfies the above conditions 1 to 5 and that is determined not to be agitated based on preset destination master information is sent to the transport line 113, and a sample that is determined to be agitated is The sample is stirred through the sample stirring device 112 and then sent to the transport line 113.

The sample rack bundle supply unit 115 is also configured as a transport belt, and an empty sample rack bundle Rb is carried into the vicinity of the robot 101B from the outside of the partition wall 100B.

[Description of effects]
The automatic sample sorting system 100 according to the embodiment of the present invention is configured as described above, and operates as follows according to teaching data preset in the controller 120.
As shown in FIG. 10, the sample container W stored in the sample rack R is transported from the previous process along the transport line 104, and in step S10, the sensor unit 103 performs laser sensor 103A and camera on each sample container W. The detection results by 103B, the identification sensor 103C, and the X-ray sensor 103D are input to the controller 120.

In step S <b> 20, the controller 120 determines whether or not each sample container W is a standard sample W <b> 1 that satisfies all the above conditions 1 to 5 based on the input information from the sensor unit 103.
If all the sample containers W stored in the sample rack R are within the standard sample W1, the process proceeds to step S60, and the sample rack R is transported on the transport line 104 as it is to reach the lead-out belt 109, where it is transported. Line 104 stops. When the transport line 104 stops, the lead-out belt 109 operates to transfer the sample rack R from the transport line 104 to the rack stock unit 107.

  In step S20, when the controller 120 determines that the sample container W that does not satisfy at least one of the above conditions 1 to 5 is stored, the sample rack R stops at a preset position on the transport belt 104. To do. At this time, in the sample rack R, the in-standard sample W1 that satisfies all of the conditions 1 to 5 and the non-standard sample W2 that does not satisfy any or all of the conditions 1 to 5 are mixedly loaded.

In step S30, either the right hand unit 11 or the left hand unit 12 operates to take out all the non-standard samples W1 except the non-standard sample W2 stored in the sample rack R as shown in FIG. In step S40, the extracted standard sample W1 is stored in an empty sample rack R that is positioned at a predetermined position near the end of the sample rack supply belt 106 and does not store anything.
In the present embodiment, the operations of step S30 and step S40 are divided into two times to transfer all the standard samples W1 to the empty sample rack R.
Step S50 is executed in parallel with step S40, and the sample rack R from which the pusher 108 operates to remove the in-standard sample W1 is transferred from the transport line 104 to the non-standard sample carry-out line 105 side.

Then, the sample rack R in which the sample W1 within the specification is stored is transported on the transport line 104 by the sample rack supply belt 106 and reaches the lead-out belt 109, where the transport line 104 stops. When the transport line 104 stops, the lead-out belt 109 operates to transfer the sample rack R from the transport line 104 to the rack stock unit 107 (step S60).
In step S70, the number of sample racks R stored in the rack stock unit 107 is counted. If the number of sample racks R does not reach a preset number (5 in this embodiment), the process returns from step S10. Processing is executed. Note that the processing from step S10 to step S70 may be executed by the right hand unit 11 and the left hand unit 12 in parallel. Thereby, processing time can be shortened.

If it is determined in step S70 that the number of sample racks R is 5, in step S80, the bundling device 110 is operated, and the sample racks R stored in the rack stock unit 107 are bound by the binding member B to form one sample. A rack bundle Rb is formed.
In step S90, the sample rack bundle Rb is held by the sample rack bundle hand 36 of either the right hand unit 11 or the left hand unit 12, and is held on the sample rack placement surface 111A of the sample rack stocker 111 in step S100. The sample rack bundle Rb is placed, and the grip of the sample rack bundle hand 36 is released.

In step S105, if it is determined that each standard sample W1 stored in the sample rack bundle Rb is required to be stirred based on preset master information, step S110 is performed for the standard sample W1 that requires stirring. Proceed to
In step S110, the standard sample W1 is taken out from the sample rack bundle Rb set in the sample rack stocker 111 by either the right hand unit 11 or the left hand unit 12 as shown in FIG. The sample W1 within the standard is transferred to the sample container storage part. Also at this time, the transfer operation of the robot 101A is performed twice for each sample rack R.
In addition, since the size of the sample W1 within the standard is smaller than the opening of the storage portion R1 of the sample rack R, when the placement surface 111A of the sample rack stocker 111 is not inclined with respect to the surface of the work table 102A, As shown in FIG. 12, the within-standard sample W1 tilts apart for each storage unit R1 of the sample rack R, and there is a case where the within-standard sample W1 cannot be gripped even when the robot 101A operates along the teaching data. It was.

  In the present embodiment, as shown in FIG. 13, since the mounting surface 111A is inclined with respect to the surface of the work table 102A by an angle a, the sample container W is inclined to the lower side of the opening of the storage portion R1, The inclination direction of the sample container W for each storage unit R1 is uniformly aligned. As a result, by teaching the teaching data the operation in consideration of the tilt direction of the sample container W, the sample can be taken from the sample rack R set in the sample rack stocker 111 without providing a new sensor such as a visual sensor in the robot 101A. The container W can be gripped more reliably.

  In step S120, the sample agitating device 112 operates to perform the agitation operation of the sample in the standard sample W1. When the sample agitation operation by the sample agitation device 112 is completed, the in-standard sample W1 is taken out from the sample agitation device 112 and transferred again to the sample rack bundle Rb set in the sample rack stocker 111.

When all the in-standard samples W1 determined to be stirred based on the supplier master information set in advance in step S105 are stirred by the sample stirring device 112, in step S140, the sample rack bundle Rb is changed to the sample rack bundle. The sample rack bundle Rb is held by the use hand 36 and transferred to the transfer line 113, and the sample rack bundle Rb is transferred to the second section by the transfer line 113.
And in the 1st division, it returns to Step S10 again and operation of Steps S10-S140 is performed.

As shown in FIG. 11, when the sample rack bundle Rb is carried in from the first section to the second section by the transport belt 113 in step T10 and the sample rack bundle Rb reaches the vicinity of the robot 101B, the robot 101B performs step T20. The sample rack bundle Rb carried by the sample rack bundle hand 36 of either the right hand unit 11 or the left hand unit 12 is gripped, and the sample gripped by any of the plurality of sample rack stockers 114 as step T30. The rack bundle Rb is placed.
At this point, the sample rack stocker 114 is prepared with an empty sorting sample rack bundle Rb associated with each carry-out line 116 by the previous control.
In step T40, the controller 120 reads the sample information for each sample W1 within the standard stored in the sample rack bundle Rb, and operates the sample container gripping hand 31 of the robot 101B based on preset destination master information. Then, each standard sample W1 carried in from the first section is transferred to the sorting sample rack bundle Rb side associated with the appropriate carry-out line 116. When all the standard samples W1 stored in the sample rack bundle Rb have been transferred to the sorting sample rack bundle Rb, the controller 120 operates the robot 101B and conveys the sample rack bundle Rb to the carry-out line 116.

Further, the controller 120 counts the number of the standard samples W1 stored in the sorting sample rack bundle Rb associated with the carry-out line 116, and when the number of the standard samples W1 reaches the preset number C ( In step T60, the robot 101B is operated to transfer the sorting sample rack bundle Rb to the associated carry-out line 116 (step T70). In step T80, the controller 120 operates the robot 101B to grip the empty sample rack bundle Rb from the sample rack bundle supply unit 115 and place it on the empty sample rack stocker 114.
Thereafter, the operations in steps T10 to T90 are repeatedly executed.

  As described above, according to the sample automatic sorting system 100 according to the present embodiment, the sorting operation of the sample container W can be automatically performed more reliably and with high accuracy without relying on the manual operation. Can save labor.

  Although the embodiment of the present invention has been described above, the automatic sample sorting system according to the present invention is not limited to the above-described embodiment, and can be appropriately modified and applied without departing from the spirit of the present invention. Is possible.
