Description

The present disclosure relates to a transport system provided with a direction correction mechanism for a transported object during transport. In particular, the present invention relates to a test tube transfer system provided with a direction correction mechanism during transfer of a holder equipped with a test tube.

For example, samples such as blood, cerebrospinal fluid, and urine collected in a dedicated test tube at the time of health diagnosis or medical treatment are subjected to the medical analyzer and necessary pretreatment before the analysis for each dedicated test tube. It is put into the sample pretreatment system and necessary analysis and pretreatment are performed.

When the test tube containing the sample is put into the analyzer or the sample inspection automation system including the analyzer and the sample pretreatment system, it is grasped by the sample chuck mechanism and a dedicated sample on which one test tube can be mounted. It is transferred to a dedicated sample rack that can mount multiple test tubes such as 5 or 10 test tubes together, and a transfer mechanism such as a line transfer mechanism and a claw feed mechanism is used to move between the devices of the sample inspection automation system. Be transported.

In a test tube transfer system that is applied to such a sample inspection automation system and has a line transfer mechanism such as a belt line, for example, by connecting a plurality of belt lines, a sample holder or a sample rack (hereinafter, both). Are collectively referred to as holders) so that they can be transported over long distances within the sample inspection automation system. An example of such a test tube transfer system is described in, for example, Patent Document 1.

On the other hand, when installing or maintaining a test tube transfer system equipped with a line transfer mechanism, the presence or absence of steps at the joints between belt lines, the parallelism of the mounting surface, the transfer state of the transported object on the belt line, etc. The inspection is usually performed using an inspection device having a sensor (eg, angle sensor, accelerometer, camera, etc.).

At that time, the inspection device can detect the presence or absence of a step at the joint of the belt line from, for example, the tilt angle measurement by the angle sensor and the sudden change measurement of the acceleration by the acceleration sensor, or measure the angle of the gravity vector using the acceleration sensor. Therefore, the parallelism of the mounting surface of the belt line is detected, and the state inside the device is detected from the video data of a specific location taken by the camera. An example of such an inspection device is described in, for example, Patent Document 2.

Further, the dedicated test tube used in the sample inspection automation system has a barcode label affixed to the outer peripheral surface in order to identify the type and processing method of the stored sample. Therefore, a bar code reader is installed in the test tube transfer system, and a test tube rotation mechanism for orienting the bar code label of the test tube so that the bar code reader can read it is also provided. An example of such a sample occupational system is described in, for example, Patent Document 3.

International Publication No. 2011/40203 International Publication No. 2016/147714 Japanese Unexamined Patent Publication No. 8-220105

In the case of the holder (single sample holder or sample rack) described in the test tube transport system described in Patent Document 1, contact with the guide wall during transport and change of holder direction at the time of transfer between belt lines, Due to friction between the belt line being driven by the stopper and the belt during standby, the holder is rotationally displaced around the vertical axis perpendicular to the bottom surface during transportation. Therefore, the orientation of the holder changes during transportation.

Further, since the test tube type inspection device described in Patent Document 2 is mounted on the holder, it is integrally rotationally displaced around the vertical axis during transportation. In the case of a holder type inspection device, it is also rotationally displaced around the vertical axis during transportation. As a result, in the inspection using the inspection device of the test tube transfer system, the detection direction of the acceleration sensor and the angular velocity sensor (hereinafter referred to as motion sensor) in the inspection device is changed due to the rotational displacement of the inspection device itself during the transfer. There was a risk of change. As a result, there is a problem that the step detection at the joint of the belt line cannot be accurately performed. Further, in the case of an inspection device equipped with a camera, there is a problem that the shooting direction of the camera is not constant and information on the transport traveling direction originally desired to be shot cannot be obtained.

Further, since the test tube to which the barcode label described in Patent Document 3 is affixed is usually mounted on a holder and transported, the test tube is integrally rotationally displaced around the vertical axis during transportation. .. Therefore, the test tube transfer system requires a test tube rotation mechanism that directs the barcode label on the peripheral surface of the rotationally displaced test tube toward the side in which the barcode reader can be read, which increases the cost. be. Further, in order for the test tube rotation mechanism to correct and rotate the test tube, it is necessary to temporarily stop the belt line being driven during that time, which causes a problem of reducing the throughput of the entire sample test automation system.

In view of the above-mentioned problems, the present disclosure is a transport system provided with a direction correction mechanism for correcting the orientation of the transported body during transport so that the direction of the transported body is a predetermined direction with respect to the transport direction. The purpose is to provide.

In order to solve the above-mentioned problems, the transport device according to the present disclosure is provided with a transport mechanism for transporting the transported body by moving and displacementing the mounting surface on which the transported body can be mounted along the extending direction of the guide. It is a transport system that is installed on the transported body and acts on the guide wall surface of the guide so that the direction of the transported body is in the same direction as the transport direction, and the transported body is displaced in the direction on the mounting surface of the transport mechanism. is allowed to have a direction correcting mechanism for correcting the direction correcting mechanism, looking at the conveyance object from the front reference direction of the carrier to match the conveying direction in the front, protrudes to the side of the conveyance object It has a guide wing that can be deformed or displaced by acting on the guide wall surface of the guide .

According to the present disclosure, it is possible to correct the orientation of the transported body during transportation so that the orientation of the transported body becomes a predetermined direction with respect to the transport direction.

As a result, in the test tube transfer system, the orientation of the holder and the orientation of the test tube and the inspection device mounted on the holder can be automatically corrected so as to be at a constant angle with respect to the transfer direction of the transfer mechanism during transfer. .. As a result, the orientation of the bar code label of the test tube mounted on the holder, the detection direction of the inspection device, and the shooting direction of the camera become constant, and the inspection accuracy of the test tube transfer system using the inspection device and the time of sample inspection The overall throughput of the sample test automation system can be improved. In addition, the test tube transfer system itself can significantly improve the transfer performance while suppressing the cost increase.

In addition, issues, configurations, and effects other than those described above in the present disclosure will be clarified by the following description of the embodiments.

It is a figure which shows the moving state of a holder when the traveling direction changes orthogonally between belt lines. It is a figure which shows the moving state of the holder traveling on a plurality of belt lines.

Hereinafter, the transfer system according to the present disclosure will be described with reference to the drawings, taking as an example the test tube transfer system applied to the sample inspection automation system.

In addition to the analyzer that analyzes the sample, the sample test automation system has a plurality of processing modules such as an input module, a pretreatment module, an opening module, a child sample preparation module, a dispensing module, a closing module, and a storage module. The plurality of processing modules are arranged and configured with respect to the test tube transfer system.

In this case, the charging module loads the sample into the system by mounting a dedicated test tube or sample container containing the sample on the holder. The pretreatment module performs the necessary pretreatment such as centrifugation on the sample in the test tube. The opening module opens a plug that seals the opening of the test tube. The child sample preparation module prepares a child sample container to be used for analysis by the analyzer. The dispensing module executes the dispensing process of the sample from the test tube to the child sample container. The closing module closes the opening of the processed test tube. The storage module transfers the test tube from the holder to the tray and stores it.

It should be noted that the above-mentioned processing contents and treatment module in the sample inspection automation system are examples, and if the sample is to be analyzed and inspected, the other processing modules may be provided to execute other processing. good.

Then, the test tube containing the sample is mounted on a dedicated holder (for example, a single sample holder, a sample rack, etc.), and the test tube transfer system including a transfer mechanism such as a belt line and a claw feed mechanism is used. It is configured to be transported between each processing module. That is, the test tube transfer system constitutes a transfer path in the test tube, that is, the sample inspection automation system of the holder on which the test tube is mounted.

On top of that, in the test tube transport system, a plurality of belt lines are appropriately connected so that the holder on which the test tube is mounted can be transported over a long distance in the sample inspection automation system. At that time, at the belt line connecting portion where the holder is transferred from one belt line to the other belt line, the transport direction of the transported object by one belt line and the transport direction of the transported object by the other belt line. By making them different (for example, at right angles), the direction of travel of the holder in the system can be changed.

FIG. 9 is a horizontal view of the moving state of the holder when the traveling direction changes orthogonally between the belt lines.
FIG. 10 is a view of the moving state of the holder when the traveling direction changes orthogonally between the belt lines as viewed from above in the vertical direction.
9 (a) and 10 (a) are views showing the transport state of the holder on the belt line of the transfer source before the transfer.
9 (b) and 10 (b) are views showing the transport state of the holder at the time of transfer from the transfer source belt line to the transfer destination belt line.
9 (c) and 10 (c) are views showing the transport state of the holder when the transfer to the belt line of the transfer destination is completed.

In the illustrated example, the test tube transport path 2 by the test tube transport system 1 has a belt line 11 in the transport direction of the object to be transported by the belt line 11-1 on one side (transfer source side) and the belt line 11 on the other side (transfer source side). The end of the belt line 11-1 and the belt are aligned with the height positions of the holder mounting surfaces of both the belt lines 11-1 and 11-2 so that the transport direction of the object to be transported by -2 is perpendicular to each other. Both the belt lines 11-1 and 11-2 are connected so as to be close to one side of the line 11-2.

Each of the belt lines 11-1 and 11-2 is configured by using, for example, a belt conveyor, and is mounted on the belt 12 by rotating and transferring the endlessly formed belt 12 in one direction by the drive roller 13. The holder 21 on which the test tube (not shown) as the object to be transported 20 is mounted can be transported in the corresponding direction. On both sides of the mounting surface of the belt lines 11-1 and 11-2 in the width direction (y direction in the figure), belt guide walls 14 for preventing the holder 21 from tipping over during transportation are provided in the transport direction (x direction in the figure). ) Is provided as appropriate.

As shown in the illustrated example, when the transport directions (x direction in the figure) of the transported objects 20 of both belt lines 11-1 and 11-2 are at right angles, one of the belt lines 11-1 is used. The end is the carry-out part on the transfer source side, and the carry-out part of the other belt line 11-2 without the belt guide wall 14 is moved. It becomes the carry-in part on the loading destination side, and the pair of carry-out parts and carry-in parts of both belt lines become the transfer part 19 of the transported body 20 between the two belt lines 11-1 and 11-2. As shown in FIG. 11 described later, when the transport direction (x direction in the figure) of the transported body 20 of both belt lines 11-3 and 11-4 is linear (same direction). , The end of one belt line 11-3 becomes the carry-out part on the transfer source side, the start end of the other belt line 11-4 becomes the carry-in part on the transfer destination side, and the carry-out part and the carry-in part are both. It becomes the transfer portion 19 of the conveyed body 20 between the belt lines 11-3 and 11-4. In these transfer portions 19, the transfer source is usually prevented from stopping or tipping over by contacting the side surface or end surface of the belt lines 11-2 and 11-4 on the transfer destination side (downstream side) with the transferred body 20. The height position of the mounting surface of the belt lines 11-1 and 11-3 is set to be equal to or higher than the height position of the mounting surface of the belt lines 11-2 and 11-4 of the transfer destination.

In the illustrated example, the belt line 11 is adopted as the line transfer mechanism 10 that transfers the transported body 20 while continuously moving it, but the line transfer mechanism 10 continuously moves the transported body 20. As long as it can be transferred, it is not limited to the belt line 11 described above, and may be, for example, a roller conveyor provided with a drive mechanism or the like.

Then, in the transfer unit 19 of such a line transfer mechanism 10 of the test tube transfer path 1, the line transfer mechanism 10 is in the transfer state even during the transfer of the transferred body 20, and the belt line 11-1 in the illustrated example. In the case of 11-2 as well, since the mounting surface is in a moving state, the holder 21 has a vertical axis perpendicular to the bottom surface (mounted surface) (in the figure, z ₀ axis, that is, the holder). Rotational displacement occurs around the central axis of 21) as described below.

For example, in the pre-transfer state shown in FIGS. 9 (a) and 10 (a) in which the entire bottom surface of the holder is mounted on the belt line 11-1 of the transfer source and the holder 21 is conveyed, the holder 21 has Through the bottom surface of the holder, the transport direction speed of the belt line 11-1 of the transfer source acts exclusively. Therefore, the holder 21 before transfer does not have a rotational displacement around the vertical axis perpendicular to the bottom surface thereof.

However, in the transfer unit 19, as shown in FIGS. 9 (b) and 10 (b), the front side portion of the belt line 11-1 on the bottom surface of the holder along the transport direction (x direction) is the transfer destination. It comes into contact with the mounting surface of the belt line 11-2, and the front side portion of the bottom surface of the holder begins to be supported by the belt line 11-2 of the transfer destination. At that time, the belt line 11-1 is transferred to the holder 21 via the unloaded portion in contact with the mounting surface of the belt line 11-1 on the rear side of the bottom surface of the holder along the transport direction (x direction) of the belt line 11-1. The transport direction speed of the belt line 11-1 of the loading source still acts and is transferred in the transport direction (x direction), and at the same time, on the front side of the bottom surface of the holder along the transport direction (x direction) of the belt line 11-1. , The transport direction speed of the transfer destination belt line 10-2 also begins to act through the carry-in start portion that is in contact with the mounting surface of the belt line 11-2. Therefore, the holder 21 is still restricted from being transferred in the transport direction (x direction) by the transfer destination belt line 11-2 due to frictional force with the mounting surface of the transfer source belt line 11-1. It is in the loading state, and due to the difference in the transport direction (x direction) between the two belt lines 11-1, 11-2, it starts to rotate and displace around the _{vertical axis (z 0 axis) perpendicular to the bottom surface.}

After that, in the transfer unit 19, as shown in FIGS. 9 (c) and 10 (c), the undelivered portion on the rear side of the bottom surface of the holder along the transport direction of the belt line 11-1 is the belt line of the transfer source. Apart from the mounting surface of 11-1, the holder 21 is no longer supported by the belt line 11-1 of the transfer source, and this time, the entire bottom surface of the holder is mounted and supported by the belt line 11-2 of the transfer destination. become. In such a transfer completion state, the transport direction speed of the transfer source belt line 11-1 does not act on the holder 21 via the bottom surface of the holder, and the transfer destination belt line 11-2 The speed in the transport direction will act exclusively. Therefore, after the transfer is completed, the holder 21 _{does not undergo rotational displacement around the vertical axis (z 0} axis) perpendicular to the bottom surface, and the rotational displacement of the holder 21 stops.

In this way, even if the belt line 11 mounted on the test tube transport path 2 changes and the transport direction of the holder 21 changes in the sample inspection automation system, the transfer portion 19 of the belt line 11 rotates in this way. By being forced to move, the orientation of the holder 21 also changes in response to a change in the transport direction.

FIG. 11 is a diagram showing a moving state of a holder traveling on a plurality of belt lines. FIG. 11 shows a state in which the test tube transport path 2 of the test tube transport system 1 is viewed from above in the vertical direction (Z-axis direction in the figure) of the sample inspection automation system.

The test tube transport path 2 has a plurality of belt lines 11-1 to 11-5 as shown in the figure (five in the illustrated example), and the transported body 20 (holder 21) is sequentially arranged by these belt lines 11. When being transported and moving within the sample inspection automation system, the orientation of the transported body 20 is also sequentially changed as described below.

In the explanation, the three-dimensional coordinate system of the sample inspection automation system, that is, the test tube transport system 1, is represented by the XYZ coordinate system, and the three-dimensional coordinate system of each belt line 11-1 to 11-5 is referred to as the traveling direction of the transported body 20. The transport direction (length direction of the belt line) is the x-axis, the direction perpendicular to the transport direction and parallel to the mounting surface (width direction of the belt line) is the y-axis, and perpendicular to the transport direction and perpendicular to the mounting surface. It is represented by an xyz coordinate system with the direction as the z-axis, and the reference direction of the holder 21 (facing the front of the holder 21) that originally matches the transport direction x of each belt line is represented by an arrow x ₀ . Then, in the illustrated example, the transported body 20 is _{initially mounted on the belt line 11-1 with its reference direction (front direction) x 0} matching the transport direction (x direction) of the belt line 11. It is assumed that they are sequentially conveyed by 11-1 to 11-5.

As shown in the figure, the reference direction x ₀ of the conveyed body 20 mounted on the belt line 11 is the transfer portion 19 between the belt lines, and the transfer direction and the transfer destination of the belt line 11 of the transfer source. Each time the transport direction of the belt line 11 is different from that of the belt line 11 and the transport direction (x direction) of each of the belt lines 11 changes before and after the transfer, the conveyed body 20 changes in the transport direction (x direction) due to the belt line 11. Change the reference direction (front direction) x _{0 according} to.

For example, as in the case of the belt line 11-1 and the belt line 11-2, the transport directions (x directions) of the transfer source and the transfer destination belt lines 11 are orthogonal to each other, and the traveling direction of the transported body 20 is the direction. At the time of conversion, in the transfer portion 19, the reference direction x ₀ of the conveyed body 20 is largely rotationally displaced around its central axis (z _{0 axis). Then, the reference direction (front direction) x 0 of the} conveyed body 20 on the XYZ coordinate system of the test tube transfer system 1 also changes.

On the other hand, as in the case of the belt line 11-3 and the belt line 11-4, the transport direction (x direction) of the belt line 11 does not change at the transfer source and the transfer destination, respectively, and the transport body 20 When the traveling body 20 travels straight in the same traveling direction, the reference direction x ₀ of the transported body 20 is not rotationally displaced in the transfer portion 19. _{Further, the reference direction (front direction) x 0 of the} conveyed body 20 on the XYZ coordinate system of the test tube transfer system 1 does not change either.

However, even during the transfer of the transported body 20 by one belt line 11, the transported body 20 is prevented from tipping over or falling on both sides of the mounting surface of the belt line 11 in the width direction (y direction). Since the belt guide wall 14 is provided, for example, when only one side surface side of the conveyed body 20 comes into contact with the belt guide wall, the conveyed body 20 is one of the width directions (y direction) of the belt line 11. In the case of so-called one-sided contact with the belt guide wall 14 on the side, a large frictional force may be generated such that the holder 21 being transferred is rotationally displaced around a vertical axis perpendicular to the bottom surface (mounted surface) thereof.

Next, the configuration of the direction correction mechanism 40 at the time of transporting the holder 21 on which the test tube 31 is mounted as the body to be transported 20, which is applied to the test tube transport system 1, will be described with reference to the drawings.

FIG. 1 is a configuration diagram of an embodiment of a direction correction mechanism included in a test tube transfer system as an embodiment of the transfer system of the present disclosure.
In FIG. 1, FIG. 1A is a front view of a transported object provided with a direction correction mechanism as viewed from its reference direction (front direction) x ₀ , and FIG. 1B is a width of the transported object. A side view viewed in the direction (y ₀ direction), FIG. 1 (c) is _{a top view (plan view) of the transported object viewed from a height direction (z 0} direction), and FIG. 1 (d) is a top view thereof. It is a perspective view of the conveyed body.

As shown in FIG. 1, the direction correction mechanism 40 of the test tube transfer system 1 according to the present embodiment has a configuration in which the test tube 31 containing the sample is integrally attached to the holder 21 on which the test tube 31 can be mounted. ..

The holder 21 has a base portion 22 having a height dimension corresponding to the height of the guide surface of the belt guide wall 14, and a holding portion 23 coaxially with the base portion 22 and integrally fixed to the upper surface of the base portion 22. It has become.

Since the holder 20 is a single sample holder in the illustrated example, the base 22 is formed in a columnar shape, and the diameter thereof is substantially equal to the width direction (y direction) of the belt line 11 and the width of the belt line 11. It is slightly smaller than the distance between the guide surfaces along the width direction of the belt line 11 between the pair of belt guide walls 14 provided in each direction. The bottom surface of the base 22 is a mounted surface with respect to the mounting surface of the belt line 11, and the peripheral surface of the base 22 is a guided surface by the belt guide wall 14 provided on the belt line 11. The shape of the base 22 is not limited to the cylindrical shape as shown in the drawing, and the guided surface that comes into contact with the guide wall surface of the belt guide wall 14 to prevent the holder 21 from tipping over or falling is provided in the width direction (y). Any shape may be used as long as it has a shape on both sides of the direction). For example, bottom isosceles triangle, rounded rectangles, such as polygonal shapes or oval shape like a home base, the three-dimensional shape is bilaterally symmetric as viewed from the reference direction (frontal) x ₀ It may be a three-dimensional member.

On the other hand, the holding portion 23 has a bottomed test tube mounting portion 24 having a hole diameter substantially equal to the outer peripheral diameter of the test tube 31 opened on the upper surface thereof, and the test tube 31 can be mounted / taken out from the opening. It has become. The bottom surface portion 24a of the test tube mounting portion 24 serves as a mounting support portion for the mounted test tube 31, and the hole wall portion 24b serves as a posture holding portion for the mounted test tube 31. In the illustrated example, the holding portion 23 is formed as a tubular member having a bottomed hole, but the configuration of the holding portion 23 is not limited to this, and the test tube 31 is mounted / taken out. Any configuration is sufficient as long as it is possible and the test tube 31 in the mounted state can be held in a predetermined posture (preferably an upright posture). For example, the holding portion 23 may have a configuration in which three or more columnar portions are erected on the upper surface of the base portion 22 along the outer periphery of the test tube 31 to be mounted. Further, the holder 21 itself is also configured to hold one test tube 31 in the holding portion 23 because the holder 21 is a single sample holder in the illustrated example, but it is similar to a sample rack. A plurality of test tubes 31 may be mounted and supported together, and the posture may be maintained.

The direction correction mechanism 40 is configured by positioning and integrally attaching the guide wing member 41 as the direction correction member to the peripheral surface of the base 22 of the holder 21.

FIG. 2 is a configuration diagram of a guide wing member constituting the direction correction mechanism shown in FIG.
In FIG. 2, FIG. 2A is a developed view of a guide wing member before molding. FIG. 2B is a plan view of the guide wing member after the molding process. FIG. 2 (c) is a front view of the guide wing member after molding, as viewed from the same direction (x _{0 direction) as the reference direction (front direction, x 0 direction in FIG. 1) of the holder.}

In this embodiment, the guide wing member 41 constituting the direction correction mechanism 40 is formed by molding a thin elastic sheet-like member made of metal or resin. In this embodiment, for example, a polypropylene sheet having a thickness of 0.2 mm is used as the thin elastic sheet-like member. The thin elastic sheet-like member is not limited to the polypropylene sheet, and may be another metal or resin thin elastic sheet-like member. Further, the thickness may be such that the rigidity capable of restoring the deformation of the guide blade portion 43, which will be described later, that occurs in the guide blade member 41 when the holder 21 is conveyed by the belt line 11 can be ensured. Regarding the thickness, the guide wing member 41 is directly attached to the outer peripheral surface of the base 22 of the holder 21 without providing a special mounting portion such as a mounting groove in the base 22 of the holder 21 to be attached, and the holder 21 is attached. It is preferably thin so that it can be conveyed by the belt line 11 without any trouble.

As shown in FIG. 2 (a), in the state of development before that molding, the guide blade member 41, both ends of a rectangular fixed base 42, the base end in the width direction of the fixing base 42 (y ₀ direction) It is configured to have a pair of guide blades 43 integrally connected to each portion. Thus, the guide blade member 41, the guide blade 43, from both ends in the width direction of the fixed base 42 (y ₀ direction), the tip is in the configuration each extending as a free end.

Here, the width direction of the fixed base 42 of the guide blade member 41 (y ₀ direction) length in the illustrated example, the peripheral surface length of about 2 minutes to 1 of the base 22 of the holder 21 (the holder 21 Assuming that the radius of the base 22 is r, the length is about π · r). The length in the height direction of the fixed base 42 (z ₀ direction) is equal to or less than the length in the height direction of the base portion 22 of the holder 21 (z ₀ direction). Further, the blade length of each guide blade 43 is such that the tip side of the guide blade 43 is the most on the holder 21 in a state where the guide blade member 41 is positioned and attached to the base 22 of the holder 21 as shown in FIG. 2 (b). even if you are deformed so as to close, which is the rear direction (x ₀ direction opposite) so as not to protrude rearward from the base portion 22 in such a length of the holder 21.

When the guide wing member 41 is attached and fixed to the base 22 of the holder 21, the fixing base 42 is curved and molded according to the peripheral surface shape of the base 22 of the holder 21, and each guide wing 43 is curved and molded. With the fixed base portion 42 attached and fixed to the peripheral surface of the base portion 22, the base end side portion 43a of the guide wing portion 43 has a predetermined angle θ ₁ (for example, 20 °) with respect to the tangential direction of the peripheral surface of the holder 21. It is bent and molded at the connection portion with the fixing base 42 so as to be separated from the peripheral surface of the holder 21 while maintaining the above position, and further, in the middle portion along the direction of the wing length, the tip end side portion 43b of the guide wing portion 43b. Is bent and molded so as to be further separated from the tangential direction of the peripheral surface of the holder 21 while maintaining a _{predetermined angle θ 2} (for example, 20 °) with respect to the extension direction of the base end side portion 43a described above. There is.

Then, the test tube conveying system 1, thus it is molded guide blades member 41, as shown in FIGS. 1 and 2, the guide blade member to the reference direction i.e. frontally of the holder 21 (x ₀ direction) 41 the combined the frontal (x ₀ direction), by the fixing base 42 of the guide blade member 41 attached and fixed to the base 22 of the holder 21, the direction correcting mechanism 40 of the tube conveying system 1 is constructed.

Thus, the reference direction is the conveying direction of the holder 21 (x ₀ direction) and in front looking at the holder 21, as shown in FIG. 1 (a), the guide wing portions 43 of the guide blade member 41, the holder 21 in the width direction _{(y 0} direction), also projects from the side surface of the base portion 22 of the holder 21, the guide blade 43, as shown in FIG. 1 (b) ~ (d) , the back from the front side of the holder 21 It extends diagonally backward while increasing the distance between the pair of guide vanes 43 toward the side. Then, the rear end of the guide wing portions 43 as viewed along the reference direction is the conveying direction of the holder 21 (x ₀ direction) (the distal portion 43 b) is so as not to protrude rearward from the rear end of the holder 21 ing.

At that time, the separation distance between the tips of the guide blades 43, which maximizes the separation distance between the pair of guide blades 43, is the belt between the pair of belt guide walls 14 provided in each of the width directions of the belt line 11. The size is equal to or greater than the distance between the guide surfaces along the width direction of the line 11. As a result, when the holder 21 is _{mounted on the belt line 11 with its reference direction (x 0} direction) aligned with the transport direction (x direction) of the belt line 11, it is provided in each of the width directions of the belt line 11. Only one of the guide blades 43 of the guide blade member 41 does not hit the guide wall surface of the pair of belt guide walls 14.

Then, the rigidity of the pair of guide wings 43 provided on the guide blades member 41 in a direction correcting mechanism 40 configured in this way, the holder 21 is the reference direction (x ₀ direction) the conveying direction of the belt line 11 ( Even if the holder 21 is mounted on the belt line 11 in the x direction and is in contact with the belt guide walls 14 and 14, the contact friction causes the holder 21 being transferred to the belt. The vane length l, vane width d, and vane of the guide vane 43, including the material and thickness of the guide vane member 41 itself described above, to the extent that the holder 21 does not stop on the line 11 and the rotational displacement of the holder 21 can be suppressed. It is adjusted by the widening angle θ ₁ , θ _{2, etc.}

Next, the function of the guide wing member 41 as the direction correction mechanism 40 provided in the holder 21 which is the conveyed body 20 will be described with reference to FIG.

FIG. 3 is an explanatory diagram of the function of the guide wing member as the direction correction mechanism provided in the holder which is the conveyed body.
3, 3 (a) is a diagram in which the reference direction of the holder 21 (x ₀ direction) showing a state that matches the conveyance direction of the belt line 11 (x-direction), and FIG. 3 (b) , (C) is _{a diagram showing a state in which the reference direction (x 0} direction) of the holder 21 is deviated by an angle δ in either the left or right direction with respect to the transport direction (x direction) of the belt line 11.

As shown in FIG. 3A, in a state where the reference direction (x ₀ direction) of the holder 21 matches the transport direction (x direction) of the belt line 11, the pair of guide wing portions 43 of the guide wing member 41 Is in a state where its tip (tip of the tip side portion 43a) is in contact with the opposite belt guide wall 14, and the diameter of the holder 21 along the transport direction (x direction) of the belt line 11 is set as the center line. , The shapes are almost line-symmetrical with each other. In such a state, even if the holder 21 is conveyed on the belt line 11, the magnitude of the drag force received by the tip of each guide vane 43 from the belt guide wall 14 is substantially the same, so that the holder 21 has a rotational moment. It hardly works. Therefore, the holder 21 is _{conveyed on the belt line 11 while maintaining a state in which the reference direction (x 0} direction) matches the conveying direction (x direction) of the belt line 11. Further, even if the tip of each guide vane 43 is about to lose the balance of the magnitude of the drag force received from the belt guide wall 14, the tip of each guide vane 43 is in contact with the belt guide wall 14. becomes the resistance of rotation of the holder 21, the reference direction of the holder 21 stabilization (x ₀ direction) is achieved.

Further, in the illustrated embodiment, in this state, the rear end of the guide wing portions 43 as viewed along the reference direction is the conveying direction of the holder 21 (x ₀ direction) (the tip of the distal portion 43 b) includes a holder 21 It does not protrude backward from the rear end. As a result, even if a large number of holders 21 are flowing on the belt line 11 and other holders 21 coming from behind collide with each other, the guide vanes 43 do not collide with other holders 21 coming from behind. Therefore, the holder 21 is difficult to rotate even if another holder 21 collides with the holder 21.

On the other hand, as shown in FIGS. 3 (b) and 3 (c), when the reference direction (x ₀ direction) of the holder 21 does not match the transport direction (x direction) of the belt line 11, the guide vane member One of the pair of guide blades 43 of 41 bends and deforms as shown by the broken line with respect to the normal state shown by the dotted line so as to come into contact with the belt guide wall 14. Then, the pair of guide blades 43 are not in a state of being substantially line-symmetrical with each other with the diameter of the holder 21 along the transport direction (x direction) of the belt line 11 as the center line. In such a state, when the holder 21 is conveyed on the belt line 11, the magnitude of the drag force received by the tip of each guide vane 43 from the belt guide wall 14 is the magnitude of the drag force of one guide vane 43. The magnitude of the drag received from the other guide wing 43 is larger than the magnitude of the drag received from the belt guide wall 14 of the other guide blade 43, that is, a so-called one-sided contact state occurs, and an imbalance occurs. Therefore, a rotational moment is applied to the holder 21 so as to balance the magnitude of the drag force received by the tip of each guide vane 43 from the belt guide wall 14. Therefore, the holder 21 is _{conveyed on the belt line 11 while being rotationally displaced so that its reference direction (x 0} direction) matches the conveying direction (x direction) of the belt line 11.

Then, in the illustrated example, as shown in FIG. 2A, the guide vane portion 43 is separated from the fixed base portion 42 so as to be separated from the fixed base portion 42 while maintaining a _{predetermined angle θ 1 with respect to the tangential direction of the peripheral surface of the holder 21. The tip side portion 43b of the guide wing portion 43 sets a predetermined angle θ 2} with respect to the extension direction of the base end side portion 43a in the middle portion along the direction of the wing length. It is configured to be bent a plurality of times so as to be further separated from the tangential direction of the peripheral surface of the holder 21 while maintaining the structure. Therefore, the guide blade portion 43 is in contact with or in contact with the belt guide wall 14 at the tip of the guide blade portion 43 (the tip of the tip end side portion 43a) regardless of whether it is in a one-sided contact state or a normal contact state. Therefore, the contact surface and the contact surface with respect to the belt guide wall 14 do not change on the vane surface of the guide vane 43, so that the balance between the guide vane 43 is less likely to be lost.

4, as shown in FIGS. 9 and 10 relates to a transfer unit 19 that the transport direction changes 90 ° between the conveying destination of the belt line 11 and the transfer source, the reference direction of the holder 21 (x ₀ direction) It is a figure which showed an example of the result of having measured the angle change using a holder motion sensor.

In FIG. 4, the change in the angle of the holder 21 in the reference direction (x _{0 direction) matches the reference direction (x 0} direction) of the holder 21 with the transport direction (x direction) of the belt line 11-1 of the transport source. Rotation around the _{central axis (z 0} axis) of the holder 21 when the case is represented by 0 ° and the case corresponding to the transport direction (x direction) of the transport destination belt line 11-2 is represented by 90 °. The angle.
In the figure, the broken line represents the rotational state of the holder 21 not equipped with the guide wing member 41 as the direction correction mechanism 40, and the solid line indicates the rotation of the same holder 21 equipped with the guide wing member 41 as the direction correction mechanism 40. It shows the state.

In this measurement, a polypropylene sheet with a thickness of 0.2 mm was used as a thin elastic sheet-like member, and the vane length l of the guide vane 43 was 11.5 mm, and θ ₁ and θ ₂ were both formed at 20 °. The feather member 41 was used. Further, for the holder motion sensor, for example, a test tube type inspection device as described in International Publication No. 2011/40203 is used, and this test tube type inspection device is replaced with the test tube 31 in the test tube mounting unit 24. It was mounted on and measured.

As a result, as shown by the broken line in FIG. 4, in the case of the holder 21 is not installed guide blade member 41 as the direction correcting mechanism 40, between the belt line, the reference direction of the holder 21 (x ₀ direction), In the end it only rotated up to 36 °.

In contrast, as shown by the solid line, the case of the holder 21 equipped with guide blades member 41 as the direction correcting mechanism 40, between the belt line, the reference direction of the holder (x ₀ direction), and finally 86 ° It was confirmed that it was rotating and well followed the change in the transport direction of the belt lines 11-1 and 11-2.

This is reflected in the fact that the holder 21 to which the guide wing member 41 is mounted continues to be rotationally displaced even after the time when the rotational displacement is stopped for 400 ms. The cause is that the entire bottom surface (mounting surface) of the holder 21 has finished moving onto the mounting surface of the belt line 11-2 to which it is transported, and the rotation of the holder 21 due to the transfer of the holder 21 between the belt lines has stopped. Even in this state, the reference direction (x ₀ direction) of the holder is still significantly different from the transport direction (x direction) of the transfer destination belt line 11-2, so that the pair of guide vane members 41 are paired. This is because the guide blade portion 43 is in a one-sided contact state as shown in FIG. 3 (c) with respect to the belt guide wall 14 of the belt line 11 of the transfer destination. As a result, due to the above-mentioned action of the guide blade member 41, the holder 21 is conveyed on the belt line 11-2 to which the guide blades are transferred, and the tip of each guide blade portion 43 receives a large amount of drag from the belt guide wall 14. This is because the holder 21 is further rotated so that the guide blades 21 are substantially equal to each other, and the holder 21 is further rotated as compared with the holder 21 to which the guide blade member 41 is not attached.

An example of the measurement result shown in FIG. 4 is the transfer portion 19 between the belt lines whose transport direction changes by 90 ° between the transfer source and the transfer destination, and the holder 21 to which the guide wing member 41 is not attached. However, this corresponds to the case where the belt line 11-2 at the transport destination is insufficiently rotated with respect to the transport direction (x direction). On the other hand, even if the holder 21 without the guide wing member 41 is over-rotated, in the case of the holder 21 with the guide wing member 41, this time, one-sided contact as shown in FIG. 3 (c). Become in a state. As a result, the holder 21 is conveyed on the belt line 11 of the transfer destination so that the magnitude of the drag force received from the belt guide wall 14 by the tips of the guide vanes 43 is substantially equal. Is rotated in the reverse direction and follows the change in the transport direction.

In addition, the insufficient rotation and over-rotation of the holder 21 with respect to the transport direction (x direction) of the belt line 11 of the transport destination in the transfer portion 19 between the belt lines 11 causes the belt lines 11 of the transport source and the transport destination. This is caused by the step between the holder mounting surfaces, the friction coefficient of the mounting surface, the relationship between the transport speeds, and the like. For example, between the belt lines of the transport source and the belt line of the transport destination, the mounting surface of the belt line 11-2 of the transport destination is lower than the mounting surface of the belt line 11-1 of the transport source as shown in FIG. If there is a difference in level, the transfer unit 19, the reference direction (x ₀ direction) of the side bottom surface of the holder 21 away from the mounting surface of the transfer origin of the belt line 11-1 (the mounting surface), the holder 21 Since the force along the transport direction does not act from the mounting surface of the belt line 11-2 at the transport destination until it comes into contact with the mounting surface of the belt line 11-2 at the transport destination due to the tilting of the belt line 11-2, there is no step. Insufficient rotation of the holder 21 occurs by the delay time of the action.

FIG. 5 is a diagram showing an example of a process of reading a barcode by a test tube transfer system to which the direction correction mechanism shown in FIG. 1 is applied.
FIG. 5A is a diagram showing a transport state of the holder on which the test tube is mounted on the belt line of the transfer source before the transfer.
FIG. 5B is a diagram showing a transport state of the holder on which the test tube is mounted at the time of transfer from the transfer source belt line to the transfer destination belt line.
FIG. 5C is a diagram showing a transport state of the holder on which the test tube is mounted when the transfer to the belt line of the transfer destination is completed.

The test tube transfer system 1 of this embodiment has a transfer unit 19 in which the transfer direction changes by 90 ° between the belt lines of the transfer source and the transfer destination, similar to those shown in FIGS. 9 and 10, of the transfer destination. A barcode reader 51 is provided on the belt guide wall 14 on the downstream side of the transfer portion 19 of the belt line 11-2 in the transport direction and on the right side of the transport direction. The barcode reader 51 reads the barcode label 52 mounted on the holder 21 and affixed to the outer peripheral surface of the test tube 31 containing the sample. A barcode is written on the barcode label 52 in order to identify the type of the contained sample and the processing method.

Tubes 31 bar code label 52 is affixed to the outer peripheral surface, a patch has been an outer circumferential surface position of the bar code label 52, is positioned with respect to the reference direction (x ₀ direction), that the front facing of the holder 21, the holder It is mounted on the test tube mounting unit 24 of 21. In the illustrated example, since the barcode reader 51 is provided with the belt guide wall 14 on the right side with respect to the transport direction of the belt line 11-2, the test tube 31 is shown with the front surface of the holder 21 facing the front. As shown in 1, the bar code label 52 is mounted on the test tube mounting portion 24 so that the outer peripheral position of the bar code label 52 is on the right side surface of the holder 21.

As a result, when the holder 21 on which the test tube 31 is mounted is loaded into the test tube transport system 1, the transport direction (x direction) of the belt line 11 to be loaded and the reference direction (x ₀ direction) of the holder 21 to be loaded are set. The holder 21 on which the test tube 31 containing the sample is mounted is placed in the transport direction between the belt line 11-1 of the transport source and the belt line 11-2 of the transport destination. As shown in FIGS. 5A to 5C, the guide wing member 41 as the direction correction mechanism 40 mounted on the holder 21 even when the belt member 19 passes through the transfer portion 19 which changes by 90 °. Due to the above-mentioned action, the bar code reader 51 provided on the belt guide wall 14 of the belt line 11-2 to which the test tube was transferred was attached to the outer peripheral surface of the test tube 31 without any special test tube rotation mechanism. The bar code label 52 can be readably and accurately faced.

In the above-described embodiment, as the direction correction mechanism 40, a thin elastic sheet-like member made of metal or resin is molded, and a pair of guide vanes 43 are integrally connected via a fixing base 42. This has been described as the guide blade member 41. However, in the configuration of the direction correction mechanism 40, _{the belt guide wall 14 is configured via each guide vane 43 so that the holder matches its reference direction (x 0} direction) with the transport direction (x direction) of the belt line 11. The specific configuration is not limited to the above-described embodiment as long as it is configured to be conveyed on the belt line 11 while maintaining a balance according to the magnitude of the drag force received from the belt line 11.

FIG. 6 is a configuration diagram of a modified example of the direction correction mechanism provided in the holder.
6, FIG. 6 (a), the upper surface viewing the holder direction correcting mechanism is provided in the height direction (z ₀ direction) diagram (plan view), FIG. 6 (b), the direction correcting mechanism is provided the holder is a side view as viewed in the width direction (y ₀ direction).

In the illustrated example, the direction correction mechanism 40 is composed of a pair of foldable guide arm mechanisms 45 provided on the base 22 of the holder 21. The foldable guide arm mechanism 45 is provided on the outer peripheral surface of the base 22 with the diameter of the base 22 along _{the reference direction (x 0} direction) of the base 22 matching the transport direction (x direction) of the belt line 11 as the center line. They are mounted so that they are line-symmetrical to each other.

The foldable guide arm mechanism 45 includes a guide arm member 46, and the base end portion of the guide arm member 46 is pivotally supported by a pin or the like and is swingably attached to the base portion 22 of the holder 21. A roller 47 is rotatably attached to the tip of the guide arm member 46, which is the swing end, and the outer peripheral surface of the roller 47 is a contact portion of the guide arm member 46 with respect to the belt guide wall 14. .. Each guide arm member 46 is in a state not in contact with the belt guide wall 14, with a predetermined angle theta ₃ between the tangential base 22 along the reference direction of the holder 21 (x ₀ direction), The tip portion is arranged so as to be separated from the base portion 22 of the holder 21. Therefore, each guide arm member 46 is urged by an urging means including, for example, a torsion spring member 48 so as to push and expand the tip end side on which the roller 47 is provided from the base end portion side.

Thus, foldable guide arm mechanism 45, as in the case of the guide wing portions 43 of the guide blade member 41 of the embodiment described above, and the reference direction is the conveying direction of the holder 21 (x ₀ direction) in the front holder looking at 21, in the width direction of the tip holder 21 of the guide arm member 46 (y ₀ direction), so as to protrude from the side surface of the base portion 22 of the holder 21. The guide arm member 46 extends diagonally backward from the front side to the back side of the holder 21 while increasing the distance between the pair of guide arm members 46. At that time, the tip of the guide arm member 46 as viewed along the reference direction is the conveying direction of the holder 21 (x ₀ direction), so as not to protrude rearward from the rear end of the holder 21.

Each guide arm member 46 is _{mounted on the belt line 11 with the reference direction (x 0} direction) of the holder 21 aligned with the transport direction (x direction) of the belt line 11, and the belt guide wall 14 of the belt line 11 is mounted. The rigidity and spring force of the guide arm member 46 and the torsion spring member 48 are adjusted so that an appropriate pressure can be applied to the wall surface via the roller 47 in contact with the guide arm member 46.

By the direction correcting mechanism 40 consisting of foldable guide arm mechanism 45 of this embodiment, as in the case of the guide wing portions 43 of the guide blade member 41 described above, the holder 21, the reference direction a (x ₀ direction) Belt The belt line is balanced according to the magnitude of the drag received from the belt guide wall 14 via the guide arm member 46 of each retractable guide arm mechanism 45 so as to match the transport direction (x direction) of the line 11. It will be transported on 11.

Then, even if the guide arm member 46 of the foldable guide arm mechanism 45 comes into contact with the belt guide wall 14 during transportation, the drag force from the belt guide wall 14 can be received via the rotatable roller 47. There is little wear, and the life of the direction correction performance can be extended.

FIG. 7 is a block diagram of an embodiment of a direction correction mechanism included in a test tube transfer system as another embodiment of the transfer system of the present disclosure.
7, FIG. 7 (a), the upper surface viewing the holder direction correcting mechanism is provided in the height direction (z ₀ direction) diagram (plan view), FIG. 7 (b), the direction correcting mechanism is provided the holder is a side view as viewed in the width direction (y ₀ direction).

In the illustrated example, the direction correction mechanism 40 has a pair of magnets 61 provided on the base 22 of the holder 21. Each magnet 61 has a line on the outer peripheral surface of the base 22 with the diameter of the base 22 along _{the reference direction (x 0} direction) of the base 22 matching the transport direction (x direction) of the belt line 11 as the center line. It is installed so that it is symmetrical. In the illustrated example, the magnets 61 are disposed so as to face the magnet surface to the outer peripheral surface of the diameter direction of the vertical base portion 22 to the reference direction of the base 22 (x ₀ direction).

Further, in the direction correction mechanism 40 of the present embodiment, as shown in FIG. 8, on the belt guide wall 14 of the belt line 11, the ferromagnetic material 62 sandwiches the transport path of the belt line 11 and the width direction of the transport path ( The configuration is such that they are provided so as to face each other in the y direction).

FIG. 8 is a diagram showing a transfer process of holders between belt lines in a test tube transfer system to which the direction correction mechanism shown in FIG. 7 is applied.

The ferromagnetic material 62 is a transfer section 19 in which the transport direction changes by 90 ° between the transfer source and the transfer destination belt lines, and the transfer section is the transfer section of the belt line 11-1 on the transfer source side and the transfer destination side. The belt guide wall 14 of the belt line 11 is provided in pairs with the carrying-in portion of the belt line 11-1 so as to face each other in the width direction (y direction) of the belt line 11 with the transport path of the belt line 11 interposed therebetween. ing. For example, iron, cobalt, and nickel are used as the material for forming the ferromagnet 62.

The direction correction mechanism 40 of the present embodiment includes magnets 61 provided on both sides of the base 22 of the holder 21 when the holder 21 passes between the pair of ferromagnets 62 and 62 provided on the belt line 11. force (attraction force) acting between the ferromagnetic member 62 corresponding to the magnet 61, function to balance the width direction (y ₀ direction) on both sides of the holder 21.

Then, in the transfer section 19 in which the transfer direction changes by 90 ° between the transfer source and the transfer destination belt lines as shown in FIG. 8, the holder 21 is provided in the transfer section of the transfer source belt line 11-1. When passing between the pair of ferromagnets 62, the reference direction (x ₀ direction) of the holder 21 first matches the transport direction (x direction) of the belt line 11-1 before the transfer is started. Is adjusted to. Then, after completing the transfer of the transfer destination of the belt line 11-2, holder 21 to which the reference direction during transfer (x ₀ direction) is changed, loading unit of transfer destination of the belt line 11-1 When passing between the pair of ferromagnetic bodies 62 provided in the above, the reference direction (x ₀ direction) of the holder 21 is adjusted to match the transport direction (x direction) of the belt line 11-2.

In the direction correction mechanism 40 of the present embodiment, a pair of ferromagnets 62 are provided on the belt guide walls 14 of the carry-out portion and the carry-in portion of the belt line 11-1, respectively. The arrangement configuration of is not limited to this. A plurality of pairs of ferromagnets 62 may be arranged on the belt guide wall 14 at appropriate intervals along the transport direction of the belt line 11.

Further, in the above embodiment, the belt guide wall 14 of the belt line 11 is provided with the ferromagnetic material 62, but the same effect can be obtained even if the belt guide wall of the belt line is made of a ferromagnetic material.

Further, the pair of ferromagnets 62 provided in the carry-out portion of the belt line 11-1 of the transport source are arranged so as to be displaced from each other along the transport direction of the belt line 11, so that the holder 21 in the transfer is carried out. Before the transfer is started, the reference direction (x ₀ direction) of the holder 21 should be shifted with respect to the transport direction (x direction) of the belt line 11-1 of the transfer source so as to compensate for the insufficient rotation of the transfer source. It may be configured as.

As described above, the specific configuration of the transfer system according to the present disclosure, particularly the test tube transfer system, is not limited to the above-described embodiment, and various modifications can be made. Further, in the embodiment, the belt line 11 is adopted as the line transfer mechanism for transferring the transported object while continuously moving it, but the line transfer mechanism transfers the transported object while continuously moving it. If so, it is not limited to the belt line 11.

In addition, when applied to a test tube transfer system, when inspecting the belt line, it is between the traveling direction of the holder or inspection device and the detection direction of the motion sensor (angular velocity sensor and acceleration sensor) in the holder. Since the angle becomes constant and it is not necessary to detect the rotation direction of the sensor (coordinate conversion by three sensors of two horizontal axes and one vertical axis is required), the number of sensors can be reduced to one. Further, since the coordinate conversion by the three sensor signals for direction detection becomes unnecessary, the calculation load can be reduced and the calculation accuracy can be improved.

Further, since the image pickup direction of the camera can be made constant with respect to the traveling direction, it becomes easy to inspect the inside of the device by an image.

Further, since the direction of the bar code label in the test tube can be made constant, the cost of the rotation mechanism for reading the bar code label and the throughput of the device can be improved.
