In addition, these units and apparatuses are configured so that a plurality of sample racks L capable of supporting ten sample containers T can be placed, and the sample racks L can be transported along the arrows in FIG. It is comprised so that. The sample transfer devices 22 and 23 are provided with a transport path r1 for transporting the sample rack L in the left direction and a transport path r2 for transporting in the right direction. The sample transfer devices 22 and 23 are connected by a single transfer path formed by connecting the transfer path r1 of the sample transfer device 22 and the transfer path r1 of the sample transfer device 23.

  FIGS. 2A and 2B are diagrams showing the configuration of the sample container T and the sample rack L, respectively. 2A is a perspective view showing the appearance of the sample container T, and FIG. 2B is a perspective view showing the appearance of the sample rack L on which ten sample containers T are supported. Note that FIG. 2B also shows the direction (the front-rear and left-right directions shown in FIG. 1) when the sample rack L is transported.

  Referring to FIG. 2A, the sample container T is a tubular container made of light-transmitting glass or synthetic resin, and has an upper end opened. On the side surface of the sample container T, a barcode label T1 is attached. A barcode including the sample ID is printed on the barcode label T1. The sample container T contains a blood sample of whole blood collected from a patient, and the opening at the upper end is sealed with a rubber lid T2.

  Referring to FIG. 2B, a barcode label L1 is attached to the rear side surface of the sample rack L. A barcode including a rack ID is printed on the barcode label L1. Further, the sample rack L is formed with a support portion that can vertically support the ten sample containers T. Hereinafter, for the sake of convenience, the positions of the respective support portions are referred to as support positions 1 to 10 from the downstream in the transport direction to the upstream.

Returning to FIG. 1, when starting measurement of a sample, the user first sets the sample container T that contains the sample in the sample rack L and places the sample rack L on the loading unit 21. The sample rack L placed on the input unit 21 is transported rearward and carried out to the sample transfer device 22.

  The sample transfer devices 22 and 23 each include a barcode unit 120, a buffer rack 140, six archive racks R1, and one sorting rack R2. As will be described later, each of the buffer rack 140, the archive rack R1, and the sorting rack R2 includes a plurality of support portions that support the sample containers T. In addition, a space for placing the sample rack L is provided in front of the sorting rack R2, and five sample racks L are installed in this space.

  The sample rack L carried out from the loading unit 21 to the sample transfer device 22 is appropriately processed by the barcode unit 120 of the sample transfer device 22 or 23. Specifically, the barcode unit 120 reads the rack ID from the barcode label L1 of the sample rack L, detects the support position where the sample container T is supported in the sample rack L, and the barcode label of the sample container T. The specimen ID is read from T1. The sample transfer device 22 or 23 transmits the sample ID read by the barcode unit 120 to the host computer 8 via the transport controller 7. Based on the measurement order and analysis result set for each sample, the host computer 8 transfers information for transferring the sample container T in the sample transfer device that has transmitted the sample ID (hereinafter referred to as “transfer information”).

  Subsequently, the sample transfer apparatus that has received the transfer information transfers the sample container T supported by the sample rack L, the buffer rack 140, the archive rack R1, the sorting rack R2, and the sorting rack according to the transfer information. The sample is transferred to a sample rack L (hereinafter collectively referred to as “storage unit”) placed in front of R2. The sample transfer device that has received the transfer information transfers the sample container T supported by the buffer rack 140 to the sample rack L as appropriate. Thereafter, the sample rack L is transported leftward and is transported to the relay unit 24.

  The sample rack L transported from the sample transfer devices 22 and 23 to the relay unit 24 is transported to the relay unit 25 when transported in the left direction and transported forward in the relay unit 24 when transported to the right direction. Then, it is carried out to the sample transfer device 23. The sample rack L transported from the relay unit 24 to the relay unit 25 is transported forward in the relay unit 25 and then transported to the transport unit 31.

  Each of the transport units 31 to 33 transports the sample rack L transported from the upstream side in accordance with an instruction from the transport controller 7. Specifically, when processing is performed by the corresponding unit and apparatus, the transport units 31 to 33 transport the sample rack L transported from the upstream side to the rear, and face the corresponding unit and apparatus, respectively.

When the measurement units 41 and 42 do not perform processing, the transport units 31 and 32 advance the sample rack L transported from the upstream side straight in the left direction, and sequentially transport the sample rack L to the downstream transport unit.

  Each of the measurement units 41 and 42 extracts the sample container T from the sample rack L transported to the front position, and measures the sample stored in the sample container T. The information processing unit 5 receives and analyzes sample measurement data from the measurement units 41 and 42, and generates an analysis result including each analysis value of the measurement item. The information processing unit 5 is communicably connected to the host computer 8 and transmits the analysis result to the host computer 8.

The smear sample preparation device 43 sucks the sample from the sample container T supported by the sample rack L at the front position, and prepares a smear sample of the sucked sample. The smear preparation apparatus 43 is communicably connected to the host computer 8 and transmits to the host computer 8 that the preparation of the smear has been completed.

  When the processing by the measurement units 41 and 42 and the smear preparation apparatus 43 is finished and the processing is no longer necessary on the downstream side, the sample rack L is transported forward in the transporting unit being transported, and then is transported by the transporting unit. Carried out upstream. Thus, the sample rack L is sequentially transported in the upstream direction.

  The sample rack L sequentially transported upstream from the transport units 31 to 33 is further transported to the right by the relay unit 25 and the relay unit 24 and is transported to the sample transfer device 23. The sample transfer device 23 carries out the sample rack L carried in from the relay unit 24 to the sample transfer device 22, and the sample transfer device 22 uses the sample rack L carried in from the sample transfer device 23 as the input unit.

  The sample rack L carried out from the sample transfer device 22 to the loading unit 21 is transported rearward in the loading unit 21 and is carried out again to the sample transfer device 22. Also in this case, as described above, reading is performed by the barcode unit 120 of the sample transfer device 22 or 23, and the sample transfer device 22 or 23 receives the transfer information from the host computer 8 and receives the received transfer. In accordance with the information, the sample container T supported by the sample rack L is transferred.

  Thus, there is no need for re-examination by the measurement units 41 and 42 and preparation of a smear again (hereinafter simply referred to as “re-examination”) by the smear preparation apparatus 43, and there is no need to perform processing other than the sample processing system 1. T is transferred to the archive rack R1 of the sample transfer device 22 or 23. Reexamination is not required, but the sample container T that needs to be processed outside the sample processing system 1 is transferred to the sorting rack R2 of the sample transfer device 22 or 23. The sample container T that needs re-examination is appropriately transferred to the sample rack L as described above, and then is carried out to the relay unit 24. The processing of the sample container T by the sample processing system 1 ends when the sample container T is transferred to the archive rack R1 or the sorting rack R2.

  The sample rack L that has been emptied after the transfer of all the supported sample containers T is carried out to the relay unit 24 and then transported forward in the relay unit 24, and then the sample transfer device 22. It is carried out to. The sample transfer device 22 carries the empty sample rack L carried in from the relay unit 24 to the loading unit 21. The empty sample rack L carried out to the loading unit 21 is transported to the right by the loading unit 21 and is carried out to the collection unit 26. The sample rack L is transported rearward in the recovery unit 26 and stored in the recovery unit 26. Thus, the transport of the sample rack L is completed.

  The transport controller 7 is communicably connected to the input unit 21, the sample transfer devices 22 and 23, the relay units 24 and 25, the recovery unit 26, and the transport units 31 to 33.

The sample rack L positioned at the position P3 is detected by the sensor s3. The sample rack L positioned at the position P3 is further transported leftward and is carried out to the relay unit 24.

  The sample rack L positioned at the position P21 is moved upward (Z-axis positive direction) by the elevating unit 130 and positioned at the position P22 (see FIG. 9C). Then, in a state where the sample rack L is positioned at the position P22, the sample container T that is supported by the sample rack L and needs to be transferred is appropriately transferred to the storage unit and the sample container supported by the buffer rack 140. T is appropriately transferred to this sample rack L. When the transfer of the sample container T to the sample rack L is completed, the sample rack L is positioned again at the position P21 by the elevating unit 130, conveyed leftward by the belt 112, and positioned at the position P3. The sample rack L positioned at the position P3 is further transported leftward and is carried out to the relay unit 24.

  The sample rack L that has been emptied after all the sample containers T are taken out at the position P22 is positioned at the position P21, and then the front surface is pushed by the rack push-out mechanism 118, whereby an empty rack storage section Extruded to 150. When the number of sample containers T supported by the buffer rack 140 reaches a predetermined value, the empty sample rack L stored in the empty rack storage unit 150 is appropriately pushed out to the position P21 by the rack push-out mechanism 151 and is moved up and down. 130 to position P22. Then, the sample container T of the buffer rack 140 is transferred to the sample rack L.

  Next, the sample rack L carried into the transport unit 160 from the downstream side is transported to the right by the belt 161 or the belt 162 of the transport unit 160 and positioned at the position P4 or the position P5. The sample rack L positioned at the position P5 is positioned at the position P4 when the rear surface is pushed by the rack push-out mechanism 163.

  FIG. 7 is a schematic diagram illustrating the configuration of the support units 230 and 240 of the container transfer unit 200.

  First, the support part 230 will be described. The support plate 231 extending in the Z-axis direction is fixed to the support member 224 of the support unit 220. The rail 232 is installed on the support plate 231, and the sliding portion 233 is slidable in the Z-axis direction with respect to the rail 232. The support member 234 is fixed to the sliding portion 233. The shaft 235 extends in the Z-axis direction, and the shaft 235 is formed with a screw-like groove. The support member 234 is installed on the shaft 235 so as to be movable in the Z-axis direction along the groove of the shaft 235 when the shaft 235 is rotated about the Z-axis. The shaft of the motor 236 is connected to the upper end of the shaft 235. When the support portion 230 is configured in this way, the support member 234 moves in the Z-axis direction by driving the motor 236.

  A light shielding plate 237 is installed on the support member 234, and a pair of light shielding sensors 238 are installed on the member installed on the support plate 231. When the support member 234 moves in the Z-axis direction, the light shielding plate 237 moves between the pair of sensors 238. Thereby, it is detected that the support member 234 is positioned on the uppermost side.

  Next, the support part 240 will be described. The support member 241 is fixed to the support member 234 of the support unit 230. A support member 242 is installed below the support member 241 with respect to the support member 241 via a spring. Below the support member 242, a grip portion 243 capable of gripping the upper portion of the sample container T from the Y-axis direction is installed. When the support portion 240 is configured in this way, the grip portion 243 can be moved in the Y-axis direction by the support portion 210, can be moved in the X-axis direction by the support portion 220, and can be moved in the Z-axis direction by the support portion 230.

  The shaft of the motor 136 is connected to the pulley 134b. When the motor 136 is driven, the pulley 134b rotates and the belt 135 moves. The sliding portion 133 is fixed to the belt 135, and moves in the vertical direction along the rail 132 when the belt 135 moves. At the left end of the sliding portion 133, a flange portion 133a is formed. When the motor 136 is driven, the collar 133a moves between the pair of sensors 137a and 137b. Thereby, it is detected that the sliding part 133, the support body 138, and the support part 139 are positioned at the upper end and the lower end.

  The support portion 139 is configured such that the width d1 in the Y-axis direction is larger than the width d2 in the short direction of the sample rack L. As a result, as shown in FIG. 8, when the horizontal surface of the support portion 139 is driven upward in the state where the lower surface of the sample rack L is supported, the sample rack L is moved upward. The support 138 is formed with an opening 138a that is larger than the width in the longitudinal direction of the sample rack L and larger than the width in the height direction of the sample rack L that supports the sample container T. As a result, the empty sample rack L positioned at the position P21 is pushed out to the empty rack storage unit 150 by the rack push-out mechanism 118 through the opening 138a.

  9A to 9C are diagrams showing a procedure for transferring the sample container T. FIG.

  As shown in FIG. 9A, the horizontal surface of the support portion 139 is inserted in advance in the spaces S1 and S2 shown in FIGS. 4 and 5A, and is positioned below the transport surface by a predetermined width. It is in a state. The state where the support portion 139 is positioned as shown in FIG. 9A is hereinafter referred to as a “standby state”. As described above, when the support unit 139 is in the standby state, the sample rack L transported in the positive X-axis direction from the position P1 is positioned at the position P21 as shown in FIG. It passes through P21 and is conveyed to position P3.

  Next, when the sample rack L is positioned at the position P21, when the sample container T is transferred with respect to the sample rack L, the support portion 139 is moved upward, as shown in FIG. 9C. This sample rack L is positioned at the position P22. Hereinafter, the state where the support portion 139 is positioned as shown in FIG. 9C is referred to as an “ascending state”. At this time, the height of the bottom surface of each support portion of the sample rack L positioned at the position P22 is H1.

  Here, the archive rack R1 and the buffer rack 140 are configured such that the height H2 of the bottom surface of the support portion R11 of the archive rack R1 and the height H3 of the bottom surface of the support portion 141 of the buffer rack 140 are equal to H1. Yes. Therefore, when the sample rack L is positioned at the position P22, H1 to H3 are equal to each other. Note that the height of the bottom surface of the support portion R21 of the sorting rack R2 and the height of the bottom surface of each support portion of the sample rack L placed in front of the sorting rack R2 are also equal to the height H1. The mounting surface of the sample rack L before the sorting rack R2 is configured. That is, in this embodiment, the height of the bottom surface of each support portion of the storage portion is all H1.

  Thus, when the support portion 139 is in the raised state (the sample rack L is positioned at the position P22), the sample container T supported by the sample rack L is appropriately transferred to the storage portion and supported by the buffer rack 140. The sample container T is transferred to the sample rack L. When the transfer of the sample container T to the sample rack L is completed, the support portion 139 is returned to the state shown in FIG. 9B, and the sample rack L is transported by the belt 112 in the X-axis positive direction. When the empty sample rack L positioned at the position P21 is pushed out to the empty rack storage unit 150, the support unit 139 is positioned further below the state shown in FIG. As a result, the empty sample rack L is pushed out in the negative Y-axis direction through the opening 138a of the support 138.

In this embodiment, when the sample container T positioned at the position P22 is being transferred, the sample rack L positioned at the position P1 is the sample rack L positioned at the position P22. Can be overtaken. That is, as shown in FIG. 9D, the horizontal plane of the support portion 139 in the raised state is higher than the lid portion T2 of the sample container T supported by the sample rack L that passes through the position P21 in the X-axis direction. Is positioned. Accordingly, the sample rack L positioned at the position P1 can pass through the position P21 under the sample rack L positioned at the position P22 without being inhibited by the support unit 139. .

  FIG. 10 is a diagram illustrating a schematic configuration of the sample transfer devices 22 and 23, the loading unit 21, and the transport controller 7. Since the sample transfer devices 22 and 23 have the same configuration, only the configuration of the sample transfer device 22 will be described below.

  The sample transfer device 22 includes a control unit 321, a communication unit 322, a barcode unit 120, a container transfer unit 200, a drive unit 323, and a sensor unit 324.

The control unit 321 communicates with the transport controller 7 via the communication unit 322.

  The drive unit 323 includes motors 116, 219, 227, 236, 136, a drive source for driving the rack extrusion mechanisms 118, 151, 163, and a drive source for driving the gripping unit 243. The sensor unit 224 includes sensors s1 to s3, 238, 245, 137a, and 137b.

  In the present embodiment, each motor included in the drive unit 323 is configured by a servo motor. That is, even if there is no optical sensor or the like for detecting where a member or the like driven by each motor included in the driving unit 323 is located, these motors can be controlled with high accuracy. Note that optical sensors (for example, the sensors 137a and 137b in FIG. 8) for detecting where the members and the like driven by the motors included in the drive unit 323 are located may be used as appropriate. In this way, each motor can be controlled with higher accuracy.

  The input unit 21 includes a control unit 311, a communication unit 312, a drive unit 313, and a sensor unit 314. The controller 311 controls each part in the making unit 21 and receives signals output from each part in the making unit 21. The control unit 311 communicates with the transport controller 7 via the communication unit 312. The relay units 24 and 25 and the recovery unit 26 have the same configuration as that of the input unit 21.

  The transport controller 7 includes a control unit 701, a communication unit 702, a hard disk 703, and a display input unit 704. The control unit 701 communicates with the input unit 21, the sample transfer device 22, the relay units 24 and 25, the collection unit 26, the transport units 31 to 33, and the host computer 8 via the communication unit 702. .

  11 and 12 are flowcharts showing the sample transfer process. This process is started when the sample rack L is positioned behind the input unit 21. In the processes shown in FIGS. 11 and 12, the sample transfer devices 22 and 23 are referred to as “first device” and “second device”, respectively, for convenience.

  Referring to FIG. 11, the control unit 701 of the transport controller 7 is in a state where the elevating unit 130 of the second apparatus is in a standby state, that is, as shown in FIG. It is determined whether or not the sample rack L is located at the position P21 (S101). This determination is made based on the drive position of the motor 136 of the elevating unit 130 and the detection signal of the sensor s2.

Subsequently, the control unit 701 determines whether the sample rack L carried out downstream from the loading unit 21 is being transported to the first apparatus immediately before the sample rack L positioned behind the loading unit 21, or Then, it is determined whether the sheet is being conveyed to the second device (S102, S103). This determination is performed based on the conveyance instruction history stored in the hard disk 703 of the conveyance controller 7 and the detection signals of the sensors s1 to s3 of the first and second devices.

  When the lifting / lowering unit 130 of the second device is on standby (S101: YES), the immediately preceding sample rack L is not being transported to the second device (S102: NO), and the lifting / lowering unit 130 of the second device is on standby (S101: NO), if the immediately preceding sample rack L is being transported to the first apparatus (S103: YES), the control unit 701 causes the first apparatus so that the sample rack L is processed by the second apparatus. And sends an instruction to the second device. Thereafter, the sample rack L is unloaded from the loading unit 21 to the first apparatus, and the process proceeds to S201.

  On the other hand, when the lifting / lowering unit 130 of the second device is not waiting (S101: NO), the immediately preceding sample rack L is not being transported to the first device (S103: NO), and the lifting / lowering unit 130 of the second device is When waiting (S101: YES) and the immediately preceding sample rack L is being transported to the second apparatus (S102: YES), the control unit 701 causes the first apparatus to process this sample rack L. An instruction is transmitted to the first and second devices. Thereafter, the sample rack L is unloaded from the loading unit 21 to the first device, and the process proceeds to S301.

  When the sample rack L is processed by the second device, the sample rack L carried out from the loading unit 21 is passed through the position P21 of the first device by the control unit 321 of the first device and carried out to the second device. Is done. At this time, when the support unit 139 of the first apparatus is in the standby state as shown in FIG. 9A, the sample rack L passes through the position P21 as shown in FIG. 9B. When the support unit 139 of the first apparatus is in the raised state as shown in FIG. 9C, the sample rack L passes through the position P21 as shown in FIG. 9D. Then, the sample rack L is transported to the position P1 of the second device by the control unit 321 of the second device (S201).

  Subsequently, the control unit 321 of the second apparatus detects at which support position of the sample rack L the sample container T is supported by the barcode unit 120 of the second apparatus, and the sample ID and the rack ID. Reading is performed (S202). Subsequently, the control unit 321 of the second apparatus inquires the host computer 8 about the transfer information of the sample container T that is supported (S203). Thereafter, the control unit 321 of the second apparatus receives the transfer information of all the sample containers T inquired in S203 (S204).

  Next, referring to FIG. 12, the control unit 321 of the second apparatus determines whether the sample container T that needs to be transferred to the sample rack L is supported based on the transfer information received in S204. Determination is made (S205). If there is no sample container T that needs to be transferred (S205: NO), the control unit 321 of the second apparatus transports the sample rack L positioned at the position P1 of the second apparatus to the left, It passes through the position P21 of the apparatus and is carried out to the relay unit 24 (S210). In S210, when the support unit 139 is not in the standby state or the raised state, the sample rack L is waited at the position P1 of the second apparatus, and when the support unit 139 is in the standby state or the raised state, this sample rack L Is passed through position P21 of the second device.

  On the other hand, when there is a sample container T that needs to be transferred (S205: YES), the control unit 321 of the second device transports the sample rack L positioned at the position P1 of the second device to the left, It positions at the position P21 of the second device (S206). Subsequently, the control unit 321 of the second device raises the sample rack L positioned at the position P21 of the second device by the support unit 139 of the second device, and positions the sample rack L at the position P22 of the second device (S207). Then, the control unit 321 of the second apparatus transfers the sample container T that is supported by the sample rack L and needs to be transferred (S208).

When the transfer of the sample container T is completed, the control unit 321 of the second device performs the position P22 of the second device.
The sample rack L positioned at is lowered and positioned at the position P21 of the second device (S209). Then, the control unit 321 of the second apparatus transports the sample rack L positioned at the position P21 of the second apparatus to the left and carries it out to the relay unit 24 (S210). Thus, the processing of the sample rack L by the second device is completed.

  Next, referring to FIG. 11, when the sample rack L is processed by the first device, the sample rack L carried out from the loading unit 21 is moved to the position P1 of the first device by the control unit 321 of the first device. (S301). Subsequently, the control unit 321 of the first apparatus detects at which support position of the sample rack L the sample container T is supported by the barcode unit 120 of the first apparatus, and the sample ID and the rack ID. Reading is performed (S302). Subsequently, the control unit 321 of the first apparatus inquires the host computer 8 about the transfer information of the sample container T that is supported (S303). Thereafter, the control unit 321 of the first apparatus receives the transfer information of all the sample containers T inquired in S303 (S304).

  Next, referring to FIG. 12, the control unit 321 of the first apparatus determines whether the sample container T that needs to be transferred to the sample rack L is supported based on the transfer information received in S304. Determination is made (S305). If there is no sample container T that needs to be transferred (S305: NO), the control unit 321 of the first apparatus transports the sample rack L positioned at the position P1 of the first apparatus to the left, And it passes the position P21 of the second device and carries it out to the relay unit 24 (S310). In S310, when the support portion 139 of the first and second devices is not in the standby state or the raised state, the sample rack L is waited at the position P1 of the first and second devices, and the support portion 139 is in the standby state or the raised state. At this time, the sample rack L is passed through the position P21 of the first and second devices.

  On the other hand, when there is a sample container T that needs to be transferred (S305: YES), the control unit 321 of the first device transports the sample rack L positioned at the position P1 of the first device in the left direction, It positions at the position P21 of the first device (S306). Subsequently, the control unit 321 of the first device raises the sample rack L positioned at the position P21 of the first device by the support unit 139 of the first device, and positions the sample rack L at the position P22 of the first device (S307). Then, the control unit 321 of the first device transfers the sample container T that is supported by the sample rack L and needs to be transferred (S308).

  When the transfer of the sample container T is completed, the control unit 321 of the first device lowers the sample rack L positioned at the position P22 of the first device and positions it at the position P21 of the first device (S309). Then, the control unit 321 of the first device transports the sample rack L positioned at the position P21 of the first device to the left, passes the position P21 of the second device, and carries it out to the relay unit 24 ( S310). Thus, the processing of the sample rack L by the first device is completed.

  As described above, according to the present embodiment, the subsequent sample rack L can be transported downstream while the sample rack L is moved upward by the support portion 139. In other words, the transport order of the sample racks L can be changed without arranging a separate transport path, and the subsequent sample racks L that are not transferred can be replaced while the sample containers T are being transferred. Can be sent downstream. Accordingly, the transport order of the sample rack L can be changed without increasing the installation area of the sample transfer devices 22 and 23, and the sample container T can be transferred efficiently.

  Further, according to the present embodiment, since the transport unit 110 is configured to allow only one sample rack L to pass, the installation area of the sample transfer devices 22 and 23 can be further suppressed. .

  Further, according to the present embodiment, the sample transfer device 22 acquires the sample transfer information based on the sample ID read by the barcode unit 120 and transfers the sample based on the acquired transfer information. Change. Thereby, based on the acquired transfer information, the support part 139 and the conveyance part 110 can be controlled smoothly.

  Moreover, according to this Embodiment, as shown to Fig.5 (a), space S1, S2 is provided and a pair of support part 139 can move space S1, S2. Accordingly, the sample rack L can be positioned at the position P21 located on the support portion 139, and then the sample rack L can be smoothly moved upward by raising the support portion 139.

  Further, according to the present embodiment, the belt 112 is driven by the motor 116 as shown in FIG. Further, since the belt 115a is hung on the pulley 113b on which the belt 111 is hung and the pulley 114a on which the belt 112 is hung, the driving of the belt 112 is transmitted to the belt 111. Thereby, the number of motors for driving the belts 111 and 112 can be suppressed, and the configuration can be simplified and the cost can be reduced.

  As mentioned above, although embodiment of this invention was described, embodiment of this invention is not limited to these.

  For example, in the above-described embodiment, the case where the measurement target of the measurement units 41 and 42 is blood is illustrated, but the measurement target of the measurement units 41 and 42 may be urine. That is, the present invention can be applied to a sample processing system including a measurement unit for measuring urine, and further, the present invention can be applied to a clinical sample processing system including a measurement unit for measuring other clinical samples. .

  In the above embodiment, the transport device including the transport unit 110 that transports the sample rack L and the elevating unit 130 that lifts and lowers the sample rack L is installed in the sample transfer devices 22 and 23. The transport apparatus can be appropriately installed in apparatuses other than the sample transfer apparatuses 22 and 23 such as the transport units 31 to 33, for example. In this way, the transport order of the sample racks L can be changed also in other apparatuses.

  In the sample processing system 1 of the above embodiment, as shown in FIG. 1, two sample transfer devices 22 and 23 are installed adjacent to each other, but only one sample transfer device is provided. It may be installed.

  In a configuration in which only one sample transfer device is installed, the subsequent sample rack L is transported downstream without waiting for an instruction from the transport controller 7 while the preceding sample rack L is moved upward. May be. For example, when the sample container T is not accommodated in the subsequent sample rack L, the control unit 321 of the sample transfer device allows the sample rack L to pass without making an inquiry to the transport controller 7 and the host computer 8. In addition, the conveyance of the sample rack L may be controlled. Alternatively, the sample transfer information held by the host computer 8 in the above embodiment may be held in the storage device of the control unit 321 of the sample transfer device. In this case, if the control unit 321 determines whether transfer is necessary based on the read sample ID and determines that transfer is not necessary for the subsequent sample rack L, it can be passed downstream.

Further, in the above embodiment, as shown in FIG. 13A, the sample container T is transferred while the sample rack L positioned at the position P21 is moved upward and positioned at the position P22. It was conducted. In this case, as shown in FIG. 13B, the moving distance of the sample container T in the X-axis direction is increased. Accordingly, as shown in FIG. 13C, after the sample rack L is positioned at the position P21, the sample rack L may be appropriately moved in an oblique direction so as to approach the support portion of the target storage portion. In this case, for example, the support member 131 of the elevating unit 130 is inclined with respect to the Z-axis direction in the XZ plane. As a result, as shown in FIG. 13 (d), the distance in the X-axis direction between the sample container T to be transferred supported by the sample rack L and the support portion of the target storage portion becomes closer. Compared to this form, the sample container T can be further quickly transferred.

  Also, as shown in FIGS. 14A and 14B, the sample rack L positioned at the position P21 is moved obliquely toward the position P23 located slightly on the Y axis positive direction side of the position P22. The sample container T may be transferred while being positioned at the position P23. In this case, for example, the support member 131 of the elevating unit 130 is inclined with respect to the Z-axis direction in the YZ plane.

  The “upward movement” described in the claims is not limited to the case where the sample rack L positioned at the position P21 is moved vertically upward and positioned at the position P22 as in the above embodiment. . In other words, the “upward movement” described in the claims refers to the case where the sample rack L is moved in an oblique direction within the XY plane, as shown in FIGS. As shown in a) and (b), the case where the sample rack L is moved obliquely in the YZ plane is also included.

  In FIGS. 13C and 13D, the sample rack L is moved in the oblique direction. Instead, after the sample rack L is moved in the Z-axis direction and positioned at the position P22, the X-axis is moved. It may be moved in the direction. 14A and 14B, the sample rack L may be moved in the Z-axis direction and positioned at the position P22, and then moved in the Y-axis direction and positioned at the position P23.

  In the above embodiment, the upward movement of the sample rack L is only from the position P21 to the position P22. However, the movement is not limited to this, and the sample rack L is moved in addition to the movement from the position P21 to the position P22. Further, it may be moved upward at another position on the transport path r1. For example, as shown in FIGS. 14C and 14D, the transport path r1 is provided with a position P24 shifted in the X-axis direction with respect to the position P21, and the sample rack L positioned at the position P24 is raised. Then, it may be positioned at the position P25. In this case, the sample rack L is positioned at any one of the positions P22 and P25 so that the sample container T to be transferred supported by the sample rack L is close to the support unit of the target storage unit. Thereby, compared with the said embodiment, the transfer of the sample container T can be performed rapidly.

  In the above embodiment, the two belts 111 and 112 are driven in conjunction with each other via the belt 115a. However, as shown in FIG. 15, only one belt 112 may be used. In the configuration shown in FIG. 15, the belts 111 and 115a are omitted from the configuration shown in FIG. 5A, and pulleys 114h and 114i are added below the pulleys 113b and 114a. The belt 112 is hung on pulleys 114 a to 114 i and is driven by a motor 116. Also in this case, a space S1 is created between the pulleys 113b and 114a, a space S2 is created between the pulleys 114b and 114e, and the support portion 139 can be inserted into the spaces S1 and S2. Thus, a configuration in which one belt 112 is separated into a plurality on the conveyance path is also included in “the belts are arranged in a plurality of regions on the conveyance path” described in the claims.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
