Further, the transport system further includes a standby time corresponding to the number of blood collection tubes received in the empty pallet 9 ′ at the start end of the pallet transport means 7, based on the information of the same blood-collected person, and Control means 11 is provided for controlling the transport means 7 and for controlling the distribution operation of the pallet distribution means 10A, 10B based on the progress of blood collection at each blood collection table 3A, 3B.

In this embodiment, the control unit 11 receives as information the number of blood collection tubes used for blood collection of the same blood collection target, ie, the number of labels issued, from the host computer on the blood collection tube preparation system side. The number of passing blood collection tubes is counted by a counter (not shown) provided on the side of the blood collection tube transport means 6, and when the number of blood collection tubes coincides with each other (that is, for the same blood-collecting person, the pallet 9 has the required number of blood collection tubes). ), The pallet transport means 7 is driven for a fixed time (the time required to move the pallet 9 from the start end to the end end of the pallet transport means 7).

In the above-described transport system, the progress of blood collection at each blood collection table 3A, 3B is determined by appropriate sensors 12C, 12D provided on the stockers 12A, 12B for supplying the blood collection tables 3A, 3B. Is to be detected. That is, when the stocker is full (for example, two pallets are full), this is detected by the sensors 12C and 12D, and the control means 11 is notified. As a result, the control means 11 operates one of the pallet distributing means 10A and 10B, and distributes the pallets 9 conveyed by the pallet conveying means 7 to the stockers that are not full.

For example, a stopper lever 101 that swings horizontally and stops the movement of the pallet on the pallet transporting means 7 is provided, and an extrusion cylinder 102 that moves the pallet to the stocker is provided.

Further, in the transport system of the present invention, a sample transport means 15 for transporting the blood collection tubes collected by the blood collection tables 3 A and 3 B to the sample collection stocker 14, for example, by mounting the blood collection tubes on the rack 13. And pallet collecting means 17 such as a belt conveyor for collecting empty pallets 9 ′ from the blood collecting tables 3 A and 3 B through the pallet return port 16 to the empty pallet supply means 8. In this embodiment, the pallet carrying means 7 and the pallet collecting means 17 are arranged vertically below the blood collection table, and the empty pallet supplying means 8 is provided at the end of the collecting means. A lift 18 for returning the pallet 9 'is provided.

In this embodiment, the blood collection tables 3A and 3B are provided with blood collection places for blood collection workers located on the left and right sides of the stockers 12A and 12B, respectively. Information reading means 4A and display means 4B are provided.

The blood collection tube after the label is attached is sequentially transported to the blood collection place by the above-described transport system, and the blood collection place is read by each blood collection operator by the information reading means 4A. According to the label information, the specific information of the blood collection subject corresponding to the label of the blood collection tube is given from the host computer 1 and displayed on the display means 4B.

[0030] Thus, the blood sampling operator obtains in advance, in addition to the specific information of the blood sampling target to be blood sampled, for example, normal blood sampling request information, and information such as AIDS patients and hepatitis patients. Necessary precautions and / or precautions should be taken when collecting blood from blood recipients.

In this embodiment, the host computer 1 gives the calling information of the blood-collected person to the notifying means 5 by a label read signal from the blood-collecting worker, and sends the blood-collected person to the corresponding blood collecting table. Tell them to go.

(First Embodiment) The sample transporting means 15 according to the present invention is configured as the first embodiment as follows. That is, the sample transport means 15 is disposed below the blood collection tables 3A and 3B, and is connected to the main transport path (hereinafter, referred to as a circulating transport path) 151 via the sample collection stocker 14 and to each of the blood collection tables. The pallet stockers 12A and 12B are provided with bypass transport paths 152A and 152B that bypass the pallet stockers 12A and 12B, and empty racks for transporting blood collection tubes that have been collected are sequentially supplied to the bypass transport paths. The racks loaded with blood collection tubes from which blood has been collected are configured to be sequentially returned from the bypass conveyance path to the circulation conveyance path 151.

Control means for switching the bypass of the empty rack from the circulation conveyance path 151 to each bypass conveyance path and the return of the blood collection tube loading rack from the bypass conveyance path to the circulation conveyance path 151 (the control described above) Means 11 included). The control means 11 is provided with a control signal from the host computer 1 and / or in each blood collecting table according to the blood collecting work situation at each work place (or as another embodiment). The switching control of the sample transporting means 15 is performed by the input from the operating means (described later).

In this case, the sample transporting means 15 has a circulating transporting path 151 disposed below the blood collection table along the pallet transporting means 7, and the bypass transporting path is The blood collection tables are arranged so as to bypass the pallet distribution points of the blood collection tables, and the empty rack 13 is configured to be loaded with blood collection tubes that have already been subjected to blood collection. Further, the control means 11 includes a first path switching actuator 153 of the rack 13 at a branch point from the circulation conveyance path 151 to the bypass conveyance path, and a rack on the circulation conveyance path 151 sent to the branch point. 13 is provided with a blood collection tube detection sensor 154 for detecting whether or not a blood collection tube has already been collected, and the signal from the blood collection tube detection sensor 154 automatically controls the path switching actuator 153 and If a blood collection tube loaded with blood collection tubes is loaded in the rack, the branch can be released and the rack 13 loaded with the blood collection tubes can be transferred to the circulating transport path 151 as it is.

In this embodiment, since all the racks 13 provided on the circulating transport path 151 in the blood collection table 3B are empty, they are unconditionally transferred from the circulating transport path 151 to the bypass transport path 152B. A rail-shaped fixed guide means 53 (see FIGS. 6 and 7) is provided so as to branch and transfer, and conversely, to join from the bypass transport path 152B to the circulation transport path 151. In the case of branch transfer from the circulating transfer path 151 to the bypass transfer path 152A, the above-described first switching actuator 153 and blood collection tube detection sensor 154 are provided (see FIG. 8). In this embodiment, the switching actuator 153 is provided with a branch guide arm 153A and a passage guide arm 153B that turn 90 degrees on a horizontal plane in response to a control signal from the control means 11.

In this case, the rack 13 is a stand type in which each blood collection tube is individually loaded, and includes a conveyor 51, 52A, 52B provided for each of the circulating transport path 151 and the bypass transport paths 152A, 152B. An annular flange 13A is formed at the lower end of each of the guides 55, 56A, and 56B provided on the left and right along the conveyor so as to be able to move along each transport path. It is located between the lower surface of the guide and the trunk 13B is located between the left and right guides to be guided.

Therefore, in each of the blood collection tables 3A and 3B, blood collection workers located on the left and right of the pallet stockers 12A and 12B place the pallet 9 on the blood collection table and attach a barcode label from the pallet 9 to the blood collection table. One of the blood vessels is picked up, and by reading the barcode by the information reading means 4A, the corresponding blood collection subject can be confirmed as described above. Then, a blood collection operation is performed on a blood collection table. After the blood collection, the blood collection tube is loaded into the empty rack 13 on the bypass transport path that bypasses the pallet stocker. On the other hand, the empty pallet 9 'is put into the collecting means 17 through the pallet return port 16. In this case, in order to securely hold the blood collection tube with respect to the rack 13, a tension coil spring 13D is stretched in a triangular shape in a plan view on the peripheral wall of the loading slot 13C of the rack 13 as shown in FIG. is there.

Further, in this embodiment, the control unit 11 controls the moving rack (the former stage) on the circulating transport path when the rack 13 loaded with blood collection tubes is transferred from the bypass transport path to the circulating transport path 151. A traffic control means 20 is provided to prevent interference with a rack which is already loaded with blood collection tubes at the blood collection table. In this case, as a first embodiment, the traffic control means 20 collects traffic in a section of the circulating transport path 151 from a branch point to the bypass transport path 152A to a junction point from the bypass transport path. A detection means 21 such as an optical sensor or a dielectric sensor for detecting the presence or absence of a rack loaded with blood vessels, and a second path switching actuator 22 for switching a path according to a detection signal of the detection means 21; When the detecting means 21 detects the rack 13 loaded with blood collection tubes on the circulating transport path 151, it controls the second path switching actuator 22 so that the rack on the circulating transport path 151 passes preferentially. It is a configuration to do. For example, here, the actuator 22 is provided with a guide arm 23 which turns 90 degrees horizontally, and can open and close the outlet of the bypass conveyance path by a control signal from the control means 11 (see FIG. 10). ).

Therefore, the rack 13 loaded with blood collection tubes at the blood collection table 3B at the preceding stage does not interfere with the rack 13 loaded with blood collection tubes at the blood collection table at the next stage at the junction of its transport path, and The sample can be sent to the circulating transport path 151 and sent to the sample collection stocker 14.

In such a configuration, unlike the conventional case where a transport means for collecting a sample is provided separately from the installation location of the blood collection table, the installation location can be omitted. The blood collection tube can be placed on the specimen transport means 15 without leaving the work position.

(Second Embodiment) This embodiment is exactly the same as the first embodiment except that the traffic control means 20 is different. That is, here, the second path switching actuator 22 is provided at the junction from the bypass conveyance path 152A to the circulation conveyance path 151, and the first path switching actuator 153 is operated, and the blood collection tube is loaded. After the rack 13 passes through the branch point to the bypass transport path 152A, the rack 13 loaded with blood collection tubes passes in the section of the circulation transport path 151 from the branch point to the junction point from the bypass transport path. In this configuration, the second path switching actuator 22 is controlled so that the rack on the circulating transport path passes preferentially for a certain period of time. That is, also in this embodiment, the guide arm 23 provided in the actuator 22 can open and close the outlet of the bypass conveyance path by the control signal of the control unit 11.

That is, in this embodiment, a predetermined time depending on the transport speed of the circulating transport path 151 is set to a predetermined length of time for the switching operation (opening / closing operation) of the path switching actuator 22 after the switching operation of the path switching actuator 153. Since the delay time is used, the detection means 21 in the first embodiment can be omitted.

(Third Embodiment) This embodiment is exactly the same as the first embodiment except that the traffic control means 20 is different. In other words, here, the traffic control means 20 operates from the branch point to the bypass conveyance path after the first path switching actuator 153 operates and the rack 13 loaded with blood collection tubes passes through the branch point. In the section of the circulating transport path 151 from the bypass transport path to the junction, the transport operation (drive of the conveyor) of the bypass transport path is stopped during the time when the rack 13 loaded with blood collection tubes passes. The configuration is such that control is performed as follows. In this case, unlike the first embodiment, the detecting means 21 and the second path switching actuator 22 can be omitted.

(Fourth Embodiment) The fourth embodiment is exactly the same as the first embodiment except that the traffic control means 20 is different. That is, here, the traffic control means 20 is provided with the second path switching actuator 22 at the junction from the bypass transport path to the circulating transport path 151, and the operating means 30 such as a control button provided on each blood sampling table is provided. The path switching actuator 22 is controlled so that a rack on the bypass transport path is preferentially passed for a certain period of time by an operation of the above-mentioned operation means (manual operation of a blood sampling operator). That is, just before the guide arm 23 exits from the bypass route, the guide arm 23 stops the passage of the rack 13 on which the blood collection tube is mounted from the circulating transport route 151 side.

(Fifth Embodiment) In these embodiments, the racks are provided with conveyors 51, 52A, 52B provided for each of the circulating transport path 151 and the bypass transport paths 152A, 152B. The guide 55, 56A, 56B provided on the left and right along the conveyor may have a rack structure capable of moving along each transport path and loading a plurality of blood collection tubes. Such a configuration is shown in FIG. Here, the rack 130 has a storage slot 131 that can store five blood collection tubes, and has a guide groove 132 formed around the guides 55, 56A, and 56B.

In the above-described embodiment of the present invention, two blood collection tables are connected and used (up to four blood collection workers can be engaged). Needless to say, in this case, a branch point to the bypass transport path in the specimen transport means 15 at the final stage of the pallet transport means 7 and a junction point therefrom to the circulating transport path are excluded. The traffic control means 20 is provided at the branching point and the merging point corresponding to each pallet stocker. The main transport path 151 of the sample transport means 15 employs a circulation type transport structure. However, a supply stocker (not shown) for accommodating an empty rack is provided at the transport start end of the main transport path 151. A sample collection stocker (not shown) is provided at the end of the transfer, and after the sample is taken from the rack, the structure of the substantially circulating transfer path is set such that the empty rack is returned to the supply stocker. May be adopted.
