If necessary, the blood collection tube carried by the first transfer means 20 is sent to the transfer conveyor 43, and the transfer conveyor 43 can send the blood collection tube to another blood collection tube automatic labeling mechanism 1. By configuring the label, even if the label creation / sticking means 30 of one of the automatic label sticking mechanisms 1 for collecting blood vessels cannot be used due to running out of label, running out of ink, clogging, etc., the other picking means that can be used without stopping the device. It becomes possible to continue the process by using the label creation and sticking means 30 of the blood vessel automatic label sticking mechanism 1.
Further, by providing the second transfer means 40 having the transfer conveyor 43 between the first transfer means 20 and the label making and attaching means 30, that is, above the automatic label collecting mechanism 1, the second transferring means Even if a problem such as clogging occurs at 40, it can be easily accessed and the problem can be easily solved.
Further, a second transfer means 40 is provided so that the blood collection tube being processed by one automatic blood collection tube labeling mechanism 1 can be sent to the other automatic label collection mechanism 1. Therefore, for example, when some trouble occurs in one of the blood collection tube automatic label sticking mechanism 1, the blood collection tube being processed is discharged on a patient-by-patient basis via the other blood collection tube automatic label sticking mechanism 1, and the trouble occurs. It is possible to restart or stop only one of the blood collection tube automatic labeling mechanism 1 in which the problem occurs.

Next, the configuration of the label creation / sticking means 30 will be described.
The label creating and attaching means 30 includes a label-attached mount supply roller 31, a mount collection roller 32, a printing and data writing means 33, a drive roller 34, a pressurizing base 35, an auxiliary roller 36, and a bar code reader 37. The roller 34, the pressurizing table 35, and the auxiliary roller 36 form a label attachment position that supports the blood collection tube at three points.
The printing and data writing means 33 prints patient information and / or sample information in the form of barcodes and characters on the surface of the label of the labeled mount, and writes necessary information on the RFID chip provided on the label. Do.
The pressurizing table 35 is configured to be movable up and down, and presses the blood collection tube supplied to the label sticking position directly by the branch cam 44 or via the transfer conveyor 43 against the drive roller 34.
At this time, since the blood collection tube is supported at three points by the drive roller 34, the pressure table 35 and the auxiliary roller 36, the drive roller 34 and the pressure table 35, the drive roller 34 and the auxiliary roller 36, and the auxiliary roller 36 and There are gaps between the pressurizing tables 35.
In this embodiment, the barcode reader 37 can read the barcode information from the blood collection tube after the label is attached through the gap formed between the drive roller 34 and the pressurizing table 35 among the above-mentioned gaps. It is arranged (see FIG. 6).
The control device 80 controls the operation of the barcode reader 37 and the drive roller 34 to attach a label to the blood collection tube and inspect whether or not the attached label is defective.
Specifically, as shown in FIG. 7, the label attached to the blood collection tube is divided into a barcode part and a print area for printing characters and the like, and further, in a state after being attached to the blood collection tube. As shown in FIG. 8, it is divided into a portion of the pipe to which the label is not attached, a portion other than the barcode of the label, and a portion of the barcode.
The control device 80 rotates the blood collection tube after the label is attached at least once by the drive roller 34 at a predetermined speed, and during that time, the bar code reader 37 continuously reads the bar code.
By continuously reading the barcode with the barcode reader 37, normally, the portion where the barcode is printed is continuously read successfully, and then the portion where the barcode of the label is not printed and the portion where the barcode is not printed and the portion where the label is printed. Barcode reading fails in areas where no label is attached. However, as shown in FIG. 9, if there is a defective portion in the barcode, reading fails at the defective portion, so that the reading success is not continuous at the barcode reading successful portion that should be continuous.
The control device 80 determines the presence or absence of a barcode defect based on the relationship between the above-mentioned reading result and the barcode defect.
Specifically, when the maximum value and the minimum value of continuous unreadable values are determined, and the number and / or time of continuous unreadable values is between the maximum value and the minimum value, the barcode is missing. Judging, the blood collection tube is regarded as an error blood collection tube.
The maximum and minimum values can be determined based on the scanning resolution of the barcode reader and the rotation speed of the tube. Specifically, for example, when the rotation speed of the tube is 130 mm / sec and the scan resolution of the barcode reader is 500 scan / sec, the minimum value is 2 scans and the maximum value is 10 scans. It is possible to detect defects between 52 mm and 2.6 mm, and the unreadable part smaller than 0.52 mm or larger than 2.6 mm is the gap between the barcodes or the part where the barcode on the label is not printed. And it is judged that the part is not labeled.
The minimum value and the maximum value can be arbitrarily determined.

After the label sticking is completed by the label making sticking means 30 and the presence or absence of the defect is determined, the pressurizing table 35 is lowered downward, and the blood collection tube after the label sticking is below the label sticking position. It is dropped on the blood collection tube discharge conveyor 60 in the above, and is collected in a tray for each patient by the blood collection tube collection mechanism 61 described later.

Here, before explaining the blood collection tube collection mechanism 61, the pipe diameter pipe length measuring means 50 provided above the second lane 23 in the first transfer means 20 will be described.
FIG. 10A is a rear view (viewed from the right side in FIG. 2) schematically showing the configuration of the pipe diameter pipe length measuring means 50, and FIG. 10B is a configuration of the pipe diameter pipe length measuring means 30. It is a right side view which shows roughly.
As shown in the drawing, the tube diameter tube length measuring means 50 laterally includes a lower side member 24 and an upper side member 51 capable of sandwiching the tube body of the collecting tube from the vertical direction in order to measure the tube diameter of the collecting tube. A left side member 52 and a right side member 53 capable of sandwiching a laid blood collection tube from the left and right, a camera member 54 for photographing the blood collection tube in a state of being sandwiched between the members, and a control device 80 for controlling these operations. Consists of.
In this embodiment, the lower side member 24 comprises a second blood collection tube rack 24. As shown in FIG. 10A, the second blood collection tube rack 24 constituting the lower side member is configured to be movable up and down in the second lane 23 by a driving member (not shown) such as a motor, and the upper side member 51 is configured. , It is configured to be movable up and down on the second lane 23, and is held at least above the second blood collection tube rack 24 by the stopper 55. The upper side member 51 has a predetermined weight, and the upper side member 51 hits the blood collection tube while the second blood collection tube rack 24 is moving upward in the second lane 23 while holding the blood collection tube. When the second blood collection tube rack 24 moves the blood collection tube upward together with the upper side member 51, the upper side member comes into contact with the blood collection tube. This enables accurate measurement of the pipe diameter.
Further, the left side member 52 and the right side member 53 are arranged further above the upper side member 51, and are configured to be movable in the lateral direction by a drive member (not shown) such as a motor via a torque limiter (not shown). .. By providing the torque limiter, it is possible to reliably sandwich the blood collection tube from the left and right by the left side member 52 and the right side member 53.
The lower side member 24 (second blood collection tube rack) and the upper side member 51, and the left side member 52 and the right side member 53 configured as described above each display an arbitrary target that facilitates image recognition on the camera member 54 side. There is. The targets of the lower side member 24 (second blood collection tube rack) and the upper side member 51 are the same or correspond to each other, and the targets of the left side member 52 and the right side member 53 are also the same or correspond to each other.
As a result, as shown in FIG. 11, the camera member 54 captures the blood collection tube sandwiched between the lower side member 24 (second blood collection tube rack) and the upper side member 51, and the left side member 52 and the right side member 53 at the top, bottom, left and right. Therefore, even if the blood collection tube is transparent, the captured image can be image-processed, and the tube diameter and the tube length of the blood collection tube can be easily and accurately measured from the distance between the targets.
The control device 80 collates whether or not the blood collection tube being processed is a blood collection tube necessary for the patient's examination based on the measurement results of the tube diameter and the tube length of the blood collection tube, and if the matching results do not match, The blood collection tube is regarded as an error blood collection tube.

The blood collection tube automatic label sticking mechanism 1 configured as described above is arranged side by side so that the blood collection tube discharge conveyor 60 and the transfer conveyor 43 of the adjacent blood collection blood collection automatic label sticking mechanism 1 are connected to each other.
All the blood collection tubes labeled by the two automatic label collection mechanisms 1 are dropped onto the blood collection tube discharge conveyor 60, and are carried to the blood collection tube collection mechanism 61 by the discharge conveyor 60.

FIG. 12 is a schematic top view of the automatic blood collection tube preparation device showing the positional relationship of each component of the blood collection tube collection mechanism 61.
The blood collection tube collection mechanism 61 is arranged adjacent to the automatic label collection mechanism 1L on the left side of the top view, and is configured to collect the label-attached blood collection tubes carried by the discharge conveyor 60 on a tray for each patient. Has been done.

As shown in FIG. 12, the tray transfer conveyor 62 is arranged from the end of the blood collection tube discharge conveyor 60 (that is, the collection position of the blood collection blood collection tube after labeling) along the left side of the automatic blood collection tube preparation device when viewed from above. It extends to the front end of the automatic blood collection tube preparation device.
A blood collection instruction issuing device 70 is arranged above the error tray collecting unit 66. The blood collection instruction issuing device 70 issues a blood collection instruction and a hand-pasted label for the corresponding patient, and discharges the blood collection instruction and the hand-pasted label to an empty tray at the collection position of the tray transfer conveyor 62.
The empty tray accommodating portion 63 is configured to stack and accommodate trays in the vertical direction, and is arranged above the tray transfer conveyor 62.
The empty tray accommodating portion 63 is configured to insert an empty tray from above and discharge the empty tray onto the tray transfer conveyor 62 from below.
The tray transfer conveyor 62 transfers the empty tray supplied from the empty tray accommodating portion 63 to the collection position. At the collection position, when a patient's blood collection tube, blood collection instruction, and, if necessary, a hand-pasted label are placed in an empty tray, the tray transfer conveyor 62 places the collected tray in front of the blood collection tube automatic preparation device. Transfer to the first tray accommodating portion 64 or the second tray accommodating portion 65 in.
The first tray accommodating portion 64 is provided adjacent to the front of the empty tray accommodating portion 63, and is configured to stack and accommodate the collected trays in the vertical direction. The first tray accommodating portion 64 lifts the collected tray on the tray transfer conveyor 62 upward and accommodates it inside the tray transfer conveyor 62, if necessary, by means of a claw or the like (not shown).
The second tray accommodating portion 65 is arranged in front of the automatic blood collection tube preparation device so as to extend along the width direction.
Specifically, the second tray accommodating portion 65 is composed of a passage having a width capable of accommodating a tray formed on the upper end surface of the blood collection tube accommodating means 2 in the two automatic blood collection tube affixing mechanisms 1. Each blood collection tube automatic label sticking mechanism 1 is provided with a label creation sticking means 30 above the blood collection tube accommodating means 2, and the label creation sticking means 30 is arranged so as to be displaced behind the blood collection tube automatic preparation device. As a result, a space is formed above the blood collection tube accommodating means 2. A second tray accommodating portion 65 is provided in the space formed above the blood collection tube accommodating means 2.
One end of the second tray accommodating portion 65 extends to the tray transfer conveyor 62, and the tray extruding means 67 is configured to extrude the tray collected from the tray transfer conveyor 62 to the second tray accommodating portion 65. ing. In the illustrated embodiment, the second tray accommodating portion 65 is configured to have a length capable of accommodating three collected trays.
With the above configuration, the collected tray in which the collection tube after the label is attached is collected for each patient is selectively stored in either the first tray storage unit 64 or the second tray storage unit 65.
For distribution of the collected trays to the first tray accommodating portion 64 and the second tray accommodating portion 65, for example, the first tray accommodating portion 64 accommodates a tray for a ward that is not immediately used, and the second tray accommodating portion 65 accommodates the tray. It is conceivable to accommodate an outpatient tray for immediate use.
Specifically, the automatic blood collection tube preparation device is configured to be able to process a mixture of preparation of an outpatient blood collection tube and preparation of a blood collection tube for a ward. For example, automatic preparation of a blood collection tube. If an order for an outpatient blood collection tube is placed while the device is preparing a blood collection tube for the ward, the collected tray containing the blood collection tube for the ward is stored in the first tray storage unit 64. However, the collected tray containing the outpatient blood collection tube is stored in the second tray storage section 65.
The error tray collection unit 66 includes an error tray transfer conveyor. The error tray transfer conveyor 66 is arranged so as to extend from one end of the tray transfer conveyor 62 to the rear of the blood collection tube automatic preparation device along the left side of the top view of the automatic blood collection tube preparation device.

Hereinafter, a control method at the time of failure in the automatic blood collection tube preparation device configured as described above will be described.
FIG. 13 is a diagram showing the movement of the tray in the collection tube collection mechanism 61 at the time of failure.
As shown in the drawing, during normal operation, an empty tray is supplied from the empty tray accommodating portion 63 onto the tray transfer conveyor 62, and the empty tray is sent to the collection position (FIG. 13 (a)).
When an error occurs, the collected blood collection tubes that can be collected in patient units are collected in a tray, and then the collected tray is once carried to the lower part of the first tray accommodating unit 64 and is made to stand by there (FIG. 13 (b)).
Then, the empty tray is sent from the empty tray accommodating unit 63 to the collection position as an error collection tray (FIG. 13 (c)).
In addition to the blood collection tube in which the error occurred, all the collection blood collection tubes remaining in the same blood collection tube automatic labeling mechanism 1 are discharged to the error collection tray, and the error collection tray is transferred to the error tray collection unit 66 (FIG. 13). (D)).
Then, the blood collection tube collected in the error collection tray is prepared again in the automatic blood collection tube preparation device, the collecting tray waiting under the first tray accommodating portion 64 is returned to the collection position, and the subsequent processing is restarted. (FIG. 13 (e)).
At this time, if necessary, the blood collection tube automatic labeling mechanism 1 in which the error has occurred can be restarted.

Next, the flow of the blood collection tube when an error occurs will be described with reference to FIGS. 14 and 15.
In the figure, UNIT1 and UNIT2 indicate the automatic label collection mechanism 1R and 1L, respectively, and the "tray changer" indicates the resolution and collection mechanism 61, respectively. Further, in the figure, "vertical transfer" is the first transfer means 20, "pipe verification unit" is the pipe diameter pipe length measuring means 50, "conveyor switching carriage" is the second transfer means 40, and "labeling position" is. The label creation / sticking means 30 and the “horizontal transport unit” mean the blood collection tube discharge conveyor 60, respectively.
The numbers assigned to the blood collection tubes are the order in which the blood collection tubes were processed.
First, with reference to FIG. 14, a process when an error occurs in the label creation / pasting means 30 will be described.
The error in the label creation / sticking means 30 may include an error in the printing and data writing means 33, as well as detection of a barcode defect described above.
In FIG. 14, it is assumed that the blood collection tube numbers 1 to 4 are the blood collection tubes required for the examination of the previous patient, and the blood collection tube numbers 5 to 8 are the blood collection tubes necessary for the examination of the next patient.
When the control device 80 detects an error blood collection tube by the label creation and sticking means 30 in the blood collection tube automatic label sticking mechanism 1R (state 1), the control device 80 first processes the blood collection tube numbers 1 and 3 on the blood collection tube automatic label sticking mechanism 1L side. To an empty tray (states 2 and 3). At the same time, the branch cam 44 sends the blood collection tube number 4, which is the blood collection tube of the same patient, to the transfer conveyor 43, and transfers the blood collection tube automatic label affixing mechanism 1R to the blood collection tube automatic label affixing mechanism 1L (state 2). It is processed by the label making and sticking means 30 of the automatic label sticking mechanism 1L and discharged to the same tray (state 3).
At this stage, the control device 80 retracts the collected tray below the first tray accommodating portion 64 by the tray transfer conveyor 62 of the resolution and collection mechanism 61 (state 4).
Next, the control device 80 supplies the empty tray as an error tray from the empty tray accommodating unit 63 (state 4), and restarts the blood collection tube automatic labeling mechanism 1R. As a result, all the blood collection tubes remaining in the blood collection tube automatic label affixing mechanism 1R (in this embodiment, the error collection blood vessels 2 and the blood collection tube numbers 6 and 8) are discharged to the error tray (state 4). After collecting all the residual collection blood vessels, the error tray is retracted by the error tray collection unit 66, and the collected tray waiting under the first tray storage unit 64 is sent to the collection position again (state 5).
As a result, the blood collection tube number 2 and the blood collection tube numbers 6 and 8 are appropriately prepared by the automatic labeling mechanism 1R for the blood collection tube after restarting, and the blood collection tube number 2 is discharged to the collected tray for patient examination. A tray containing the necessary blood collection tubes is completed (state 6). This tray is accommodated in the first tray accommodating portion 64 or the second tray accommodating portion 65 (state 7).
With the above configuration, the blood collection tube processed by the error-free automatic blood collection tube labeling mechanism 1R is not wasted, and the blood collection tube being processed by the error-caused automatic blood collection tube labeling device 1L is not wasted. Even so, if it is the same patient's blood collection tube, it is configured so that it can be collected together with the treated blood collection tube without discarding it, so that there is no waste in this respect as well.

Next, processing when an error occurs in the pipe diameter pipe length measuring means 50 will be described with reference to FIG.
In FIG. 15, it is assumed that the blood collection tube numbers 1 to 4 are the blood collection tubes required for the examination of the previous patient, and the blood collection tube numbers 5 to 8 are the blood collection tubes necessary for the examination of the next patient.
When the control device 80 detects an error blood collection tube in the tube diameter tube length measuring means 50 in the blood collection tube automatic label affixing mechanism 1R (state 1), in the case of this embodiment, the blood collection tube in which the error occurs is the previous patient. Since the blood collection tube numbers 6 are after the blood collection tube numbers 1 to 4, the treatments of the blood collection tube numbers 1 to 4 are performed first, and they are stored in an empty tray (state 2). Then, since the collected trays containing the blood collection tube numbers 1 to 4 contain all the blood collection tubes, they are sent to the first tray storage section 64 or the second tray storage section 65 (state 3).
At this stage, the control device 80 supplies the empty tray as an error tray from the empty tray accommodating unit 63 (state 4), and restarts the blood collection tube automatic labeling mechanism 1R. As a result, all the blood collection tubes remaining in the blood collection tube automatic label affixing mechanism 1R (in this embodiment, error blood collection tube numbers 6 and blood collection tube numbers 8) are discharged to the error tray (state 4). After collecting all the residual collection blood vessels, the error tray is retracted by the error tray collection unit 66, and the collected tray waiting under the first tray storage unit 64 is sent to the collection position again (state 5).
As a result, the blood collection tube numbers 6 and 8 are appropriately prepared by the automatic labeling mechanism 1R for blood collection blood collection after restarting (state 6), the empty tray is supplied from the empty tray storage unit 63, and the blood collection tube of the next patient is collected. Collect all the numbers 6 to 8 in the empty tray (state 7).

As described above, according to the automatic blood collection tube preparation device according to the present embodiment, when an error occurs in any of a plurality of (two in this example) automatic blood collection tube affixing mechanisms 1L and 1R, When an error occurs, the blood collection tubes that can be discharged on a patient-by-patient basis are processed, and those blood collection tubes are collected on a tray on a patient-by-patient basis, and then only the automatic labeling mechanism for the blood collection tube in which the error occurred is restarted. As a result, the blood collection tube being processed by the automatic labeling mechanism for blood collection tubes that has not caused an error is maintained as it is, and the restarted automatic label collection mechanism for blood collection tubes reprocesses the residual blood collection tubes discharged due to the restart. And return to the state before the error.
As a result, there is no waste of the blood collection tube and the processing speed is faster than that of the conventional device in which the entire automatic blood collection tube preparation device is restarted when an error occurs.
In a device that performs complicated processing such as an automatic labeling mechanism for blood collection tubes, there is a high possibility that the error will be resolved by restarting when an error occurs, but as described above, in the conventional automatic blood collection tube preparation device, the device The whole thing has to be restarted. If the entire device is restarted, it will take some time before the device can be used again, and even the blood collection tube being processed by the error-free automatic blood collection tube affixing mechanism will be discarded as residual blood collection tube. , In reality, they often try to deal with it without restarting. According to the automatic blood collection tube preparation device of this embodiment, since only the automatic blood collection tube labeling mechanism in which an error has occurred can be restarted, the time required for restarting is short and wasteful. It is possible to reduce the number of blood collection tubes as much as possible.
