  Here, the operation of taking out the blood collection tray 7 will be described in detail by taking, as an example, the case where only the tray request switch 40 in the blood collection table 20 positioned on the uppermost stream is pressed. When the request switch 40 is pressed, the blood collection tray preparation device 10 lowers the tray stopper 17 and transfers the blood collection tray 7 maintained at the standby position P3 to the blood collection table 20 side. At this time, the supply conveyor 24 of the blood collection table 20 also operates together, and the supply conveyor 24 receives the blood collection tray 7 supplied from the blood collection tray supply conveyor 12 of the blood collection tray preparation device 10. Are transferred further downstream (right side in FIG. 1). Although the tray stoppers 30 and 31 of the blood collection table 20 located at the most upstream position are usually sunk below the transfer surface of the supply conveyor 24, when the tray request switch 40 is pressed, the blood collection tray 7 to be taken out When the blood collection table 20 is intruded, only the downstream side tray stopper 31 ascends above the transfer surface. As a result, the blood collection tray 7 transferred by the supply conveyor 24 is locked to the tray stopper 31 and remains at the tray take-out position P4. When the second tray detection sensor 42 detects the blood collection tray 7 in the blood collection stand to take out the blood collection tray 7, the control device 4 reduces the speed of the supply conveyor 12 of the blood collection stand 20 for collecting blood. The tray 7 is prevented from hitting the tray stopper 31 at high speed. When it is detected by the third tray detection sensor 43 that the blood collection tray 7 has reached the takeout position P4, the upstream side tray stopper 30 also rises above the transfer surface of the supply conveyor 24, and the blood collection tray 7 is The sheet is held at the tray take-out position P4 by being pinched by the tray stoppers 30 and 31. Subsequently, the extraction arm 29 is moved along the arm guide 28 toward the front side (the lower side in FIG. 1) of the blood collection table 20 to push the blood collection tray 7 out of the supply conveyor 24 into the blood collection tray extraction passage 26. The removal arm 29 retracts the blood collection tray 7 to an initial position behind the supply conveyor 24 after the collection tray 7 is placed on the receiving surface of the receiving table 27. The home position detection sensor 29a detects that the extraction arm 29 is at the initial position, and it is determined that the series of blood collection tray extraction operations described above are completed.

Hereinafter, a tray transfer control method in the blood collection tray transfer system Y configured as described above will be described based on two examples shown in FIGS. 4 and 5.
FIGS. 4 (a) to 4 (g) are schematic views showing an example of tray transfer operation of the blood collection tray transfer system according to the present invention.
In this embodiment, six blood collection tables 20a to 20g are arranged in series.
The configuration of each of the blood collection tables 20a to 20g is the same as the configuration of the blood collection table described with reference to FIG.
FIG. 4A shows an initial state, in which two blood collection trays A and B stand by in the blood collection tray supply device 10. In this state, when the blood collection operator of the fifth blood collection table 20e first presses the tray request switch and then the blood collection operator of the sixth blood collection table 20 g presses the tray request switch,
As shown in FIG. 4B, the tray supply device 10 for blood collection releases the first tray A from the standby position P3, transfers it to the first blood collection table 20a, and holds the next tray B in the standby position P3. .
When tray A comes out of the first blood collection table 20a and enters the second blood collection table 20b, the control device 4 determines that the "tray transfer operation" in the first blood collection table 20a is completed, and supplies the blood collection tray. The apparatus 10 starts the transfer of the next tray B. Thus, the tray B is delivered to the first blood collection table 20a (see FIG. 4 (c)). The withdrawal of the tray A from the blood collection table 20a is detected by the third tray detection sensor 43 (not shown, see the description of FIG. 3) provided on the blood collection table 20a, and the tray to the second blood collection table 20b The entry of A is detected by a first tray detection sensor 41 (not shown, see the description of FIG. 3) provided on the blood collection table 20b.
As described above, when it is determined that the tray transfer operation at the adjacent downstream blood collection table is completed, the transfer of the next blood collection tray B is started.
When the blood collection tray A reaches the target blood collection table 20e (that is, the blood collection table on which the tray request switch is pressed), the tray stopper of the blood collection table 20e ascends and holds the tray A at the takeout position P4, The take-out arm takes out the tray A. At this time, in the next tray B, the passage of the tray A is not detected in the upstream adjacent blood collection table 20e, and the end of the taking-out operation of the tray A is not detected, so the downstream of the blood collection table 20e It is held by the tray fixing means in the blood collection table 20d adjacent to (see FIG. 4 (d)).
When it is detected by the home position detection sensor 29a (not shown, refer to the explanation of FIG. 3) that the takeout arm returns to the initial position in the blood collection table 20e, the tray transfer operation in the upstream adjacent blood collection table 20e is completed. Then, the tray stopper on the blood collection table 20 adjacent to the downstream side descends to release the waiting tray B, and the transfer of the tray B is resumed (see FIG. 4E).
Since there is no tray A being transferred upstream of the tray B, the tray B is transferred as it is to the target blood collection table 20f (see FIG. 4 (f)).
Finally, the tray B is supplied to the tray receiving table by the operation of the tray stopper and the takeout arm in the target blood collecting table 20f.
As described above, according to the blood collection tray transfer system Y according to the present invention, it becomes possible to start the transfer of the next tray B before the transfer of the previous tray A is completed. During the operation, since the next tray B is always transferred to the previous blood collection table, the time taken to transfer the tray can be minimized, and as a result, the blood collection operator requests the tray. Then, it is possible to minimize the time for the tray to reach the tray receiving table at hand. This allows blood collection to proceed smoothly and reduces patient waiting time. At the same time, it is possible to shorten the waiting time of the tray worker for the blood collection worker.

Next, with reference to FIGS. 5A to 5F, another embodiment of the tray transfer operation of the blood collection tray transfer system according to the present invention will be described.
Also in this embodiment, six blood collection tables 20a to 20g are arranged in series.
The configuration of each of the blood collection tables 20a to 20g is the same as the configuration of the blood collection table described using FIG. 3 as in the embodiment of FIG.
FIG. 5A shows an initial state, in which two blood collection trays A and B are on standby in the blood collection tray supply device 10. In this state, when the blood collection worker of the sixth blood collection table 20f first presses the tray request switch, and then the blood collection worker of the second blood collection table 20b presses the tray request switch,
As shown in FIG. 5B, the tray supply device 10 for blood collection releases the first tray A from the standby position P3, transfers it to the first blood collection table 20a, and holds the next tray B at the standby position P3. .
When tray A comes out of the first blood collection table 20a and enters the second blood collection table 20b, the control device 4 determines that the "tray transfer operation" in the first blood collection table 20a is completed, and supplies the blood collection tray. The apparatus 10 starts the transfer of the next tray B. Thus, the tray B is delivered to the first blood collection table 20a (see FIG. 5C).
As described above, when it is determined that the tray transfer operation at the adjacent downstream blood collection table 20 is completed, the transfer of the next blood collection tray B is started.
Next, when the blood collection tray A comes out of the second blood collection table 20b and enters the third blood collection table 20c, the control device determines that the "tray transfer operation" in the second blood collection table 20b is completed, The transfer of the blood collection tray B waiting on the first blood collection table 20a is resumed. (See FIG. 5 (c)).
As a result, while the first blood collection tray A is transferred to the target blood collection table 20f, the next blood collection tray B reaches the target blood collection table 20b (see FIG. 5 (d)).
The blood collection tray B that has reached the target blood collection table 20b is taken out to the tray receiving table of the blood collection table 20b by the action of the tray stopper of the blood collection table 20b and the extraction arm. During this time, the first tray A is still being transferred to the target blood collection table 20f (see FIG. 5 (e)).
Then, when the tray A arrives at the target blood collection table 20f, it is taken out to the tray receiving table of the blood collection table 20f by the action of the tray stopper of the blood collection table 20f and the extraction arm (see FIG. 5 (f)). .
In the conventional blood collection tray transfer system, the next tray B is on standby at the blood collection tray supply device 10 until the tray A arrives at the blood collection table 20f and is taken out to the tray receiving table. By using the tray transfer system, it can be seen that the transfer of the tray B is completed before the transfer of the tray A is completed, and the transfer time of the tray is significantly reduced.
As a result, the tray waiting time of the blood collecting worker can be reduced, and as a result, the blood collecting operation can be made efficient, so that the waiting time of the patient can be reduced.
At the site of blood collection, the waiting time of the patient waiting for blood collection causes great stress to the patient, and the increase of the waiting time until the tray reaches the hand causes the concentration of the blood collection worker to be reduced. As a result, the reduction of tray waiting time by the blood collection tray transfer system according to the present invention is extremely effective in this field.

In the above-described embodiment, each blood collection table 20 is provided with a first tray detection sensor 41 for detecting intrusion into the blood collection table and a third tray detection sensor 43 for detecting withdrawal from the blood collection table, and detection of these sensors Based on the results, it is detected whether or not the tray for blood collection has passed through the blood collection platform, but whether or not the tray for blood collection has detected the blood collection platform, that is, tray transfer operation in the blood collection platform located downstream The configuration and method for detecting whether or not the present invention is not limited to the present embodiment.
