Description

Technical Field

[0001] The present invention relates to a container installation device.

Background Art

[0002] Generally, when performing biochemical tests or microbiological tests, specimen containers are used to collect and temporarily store specimens. As such specimen containers, for example, those that can seal specimens with screw caps are used. In order to test specimens at a testing institution, it is necessary to open the screw caps of a plurality of specimen containers to take out the specimens. With the automation of testing, efforts are being made to automate the opening of specimen containers as well.

[0003] For example, Patent Document 1 describes a technique for opening and closing the screw cap of a specimen container while two gripping mechanisms cooperate. Specifically, with the hand part of the first robot arm part gripping the main body part of the specimen container, the lid opening and closing mechanism grips the screw cap of the specimen container and opens and closes it while cooperating with the hand part of the first robot arm part.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the technique disclosed in Patent Document 1 above, with the hand part of the first robot arm part gripping the main body part of the specimen container, the lid opening and closing mechanism needs to grip the screw cap of the specimen container. Therefore, the mechanism for gripping the main body part of the specimen container becomes complicated, and it is impossible to hold a plurality of specimen containers simultaneously.

[0006] For example, when accelerating the opening of caps of specimen containers arranged in a plurality on a container mounting table, a mechanism for simultaneously gripping a plurality of specimen containers is required by a mechanism for gripping the main body of the specimen container. However, in a multi-row type container mounting table, there are other containers on both sides of the container, and a mechanism for gripping the specimen container cannot be installed. Even if it could be set, there is a problem that the structure of the gripping mechanism becomes complicated. Also, a barcode label or the like is often attached to the opposite part of the specimen container, but there is also a risk of problems such as damaging the barcode and making it unreadable by the mechanism for gripping the specimen container.

[0007] Also, for example, when gripping the main body of a specimen container with a rotation-preventing rubber sheet, depending on the relationship between the hole dimensions on the rubber sheet side and the dimensions of the main body of the specimen container, if it is too tight, it may not fit, or if it is too loose, rotation cannot be prevented, etc. Therefore, there is a problem that it is difficult to adjust the dimensions. Also, when inserting the specimen container into the hole on the rubber sheet side, there is a problem that the barcode label attached to the specimen container peels off and it cannot be lifted when moving the container with a transport device.

[0008] Furthermore, for example, when providing special rotation-preventing means on the main body side of the specimen container instead of gripping the main body of the specimen container with a rotation-preventing rubber sheet, corresponding to various specifications of rotation-preventing means, the specimen container mounting table also becomes dedicated for each of various containers and cannot be compatible with other containers, which is a problem.

[0009] An object of the present invention is to provide a container installation device that can prevent the rotation of the container body with a simple structure when opening and closing the cap of a container with a cap, and moreover, can be compatible with a plurality of containers.

Means for Solving the Problems

[0010] The container installation device according to the first aspect of the present invention is a container installation device for installing a container with a cap, and at least includes a container installation part on which the bottom of the container is installed. On the container installation part, one or more blade plates protruding toward the bottom surface of the container are provided. The blade plates engage with the bottom of the container, and the degree of engagement of the blade plates with the bottom of the container is set to such an extent that the rotation of the container can be restricted even when an external force in a direction attempting to rotate the container around the axis of the container acts with the attachment and detachment of the cap.

[0011] The container installation device according to the second aspect of the present invention is the container installation device according to the first aspect, wherein a cutting edge is provided at the tip of the blade plate facing the bottom of the container, and a cap holding mechanism for holding the cap, in a state of gripping the cap, is characterized in that the cutting edge bites into the bottom of the container.

[0012] In the container installation device according to the third aspect of the present invention, in the container installation device according to the second aspect, when the amount by which the cutting edge bites into the bottom of the container is defined as the biting amount c, the biting amount c is 0.05 mm ≤ c ≤ 0.3 mm and is set to be such.

[0015] The container installation device according to the sixth aspect of the present invention is the container installation device according to the third aspect, wherein the container is made of resin, and when the hardness of the resin of the container is the Rockwell hardness R, the indentation amount c is c = γR + δ 0.2 ≤ δ ≤ 0.7 -0.001 ≤ γ ≤ -0.005 It is characterized by being set so as to satisfy the relational expression of

Advantages of the Invention

[0016] According to the container installation device of the first aspect of the present invention, one or more blade plates protruding toward the bottom surface of the container provided in the container installation portion engage with the bottom of the container, so that when opening and closing the cap of the container with a cap, rotation prevention of the container body can be realized with a simple structure, and moreover, it can also cope with a plurality of containers. Moreover, the degree of engagement of the blade plate with the bottom of the container is set to such an extent that the rotation of the container can be restricted even when an external force in the direction of trying to rotate the container around the axis of the container acts with the attachment and detachment of the cap, so that the degree of engagement of the blade plate with the bottom of the container can be appropriately set.

[0017] According to the container installation device of the second aspect of the present invention, the cap holding mechanism that holds the cap can surely prevent the rotation of the container body during the opening and closing operation of the container because the cutting blade bites into the bottom of the container while gripping the cap.

[0018] According to the container installation device of the third aspect of the present invention, when the amount of indentation of the cutting blade into the bottom of the container is the indentation amount c, the indentation amount c is 0.05 mm ≤ c ≤ 0.3 mm Since it is set so as to achieve, the rotation of the container body can be surely prevented. Further, since the indentation amount c is limited by the upper limit value where it is not desired to damage the bottom surface of the container as much as possible, the degree of damage to the container can be suppressed within an appropriate range.

[0019] According to the container installation device of the fourth aspect of the present invention, when the angle formed by the portion of the cutting blade that bites into the bottom of the container and the plane on which the container installation portion is provided is defined as angle α, the angle α is 0°≦α<90° By being set in this way, it is possible to reliably prevent the rotation of the container body with respect to containers of various specifications. For example, by setting the angle α according to the shape of the bottom of the container, it is possible to reliably prevent the rotation of the container body whether the bottom of the container is flat or curved.

[0020] According to the container installation device of the fifth aspect of the present invention, in the vertical plane including the axis of the container installed in the container installation portion, when the angle formed by the tangent line of the portion where the bottom of the container engages with the cutting blade and the plane on which the container installation portion is provided is defined as β, the relational expression between the angle α and the angle β is -30°≦α-β≦30° By being set in this way, for containers of various specifications, since the angle of the cutting blade is appropriately set according to the bottom shape of the container body, it is possible to reliably prevent the rotation of the container body.

[0021] According to the container installation device of the sixth aspect of the present invention, when the hardness of the resin of the container is the Rockwell hardness R, the penetration amount c is c=γR+δ 0.12≦δ1≦0.7 -0.005≦γ1≦-0.00059 Since it is set to satisfy the relational expression, for containers of various specifications, even when the resin materials are different, an appropriate penetration amount according to the hardness of the resin can be set, so that the rotation of the container body can be reliably prevented for containers of various materials.

Mode for Carrying Out the Invention

[0023] Hereinafter, the container installation device according to the embodiment of the present invention will be described in detail with reference to the drawings. However, the embodiments shown below are examples of the container installation device for embodying the technical idea of the present invention, and do not specify the present invention thereto, and can be equally applied to other embodiments included in the claims. In the embodiments of the present invention, as a specific example of the container installation device, the container installation table will be described together with the drawings. However, this embodiment is not limited to the container installation table in the form shown in the drawings, and is applicable to container installation devices of various specifications.

[0024] [Embodiment 1] The container installation device according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 7.

[0025] FIG. 1 is a partial cross-sectional view showing the outline of the container installation device of Embodiment 1 of Embodiment 1. The container installation table 20 as the container installation device includes an upper plate 21, a support column 22 that supports the upper plate, and a bottom plate 23 on which the support column is supported. A plurality of container installation portions 30 are provided on the bottom plate 23. The container installation portion 30 is not particularly limited, but is configured as a cylindrical groove portion. The container installation portion 30 has, for example, a circular planar container installation bottom surface 31 on which the bottom of the container 10 is installed, a container installation side surface 32 that rises, for example, cylindrically from the outer periphery of the container installation bottom surface 31, and a container guide surface 33 that has a shape that spreads, for example, in a mortar shape, from above the container installation side surface 32 toward the upper surface (since the upper direction is drawn as vertically upward in FIG. 1, the terms "upper" and "upper surface" are used. The same applies hereinafter).

[0026] The container 10 has a container body 11 and a cap 12. The container body 11 is a bottomed cylindrical shape. Although not particularly limited, the container body 11 is, for example, transparent or translucent so that the state of accommodating the specimen can be confirmed from the outside. In addition, a label seal for identifying the specimen or the like, which is the content, is often attached to the container body.

[0027] Examples of the cap 12 include a screw cap that is screwed onto a male screw provided at the opening of the container body 11, but the cap 12 is not necessarily limited to a screw cap. For example, a rubber cap that seals the opening of the container body 11 with the elastic force of rubber, or a resin fitting cap that utilizes the elastic force of resin and shape coupling by uneven shapes can also be adopted. In the present embodiment, any type of cap 12 can be adopted as long as a means for preventing the rotation of the container body 11 is required when the cap 12 is opened and closed. A container planar bottom 15 as the bottom of the container is provided at the bottom of the container body 11 of 10.

[0028] On the upper plate 21, at positions corresponding to the container installation parts 30, the same number of container insertion holes 25 as the container installation parts are provided. The container body 11 is installed with the container flat bottom 15 on the container installation part 30, and between the container flat bottom 15 and the opening of the container body 11, by being inserted into the container insertion hole 25, it is installed on the container installation part 30 so as not to fall over. The inner diameter dimension of the container installation side surface 32 of the container installation part 30 and the inner diameter dimension of the container insertion hole 25 are slightly larger than the outer diameter dimension of the container body 11, and although not particularly limited, they are set to be about 0.05 mm to 2 mm larger. With this dimension setting, the container body 11 is stably installed on the container installation table 20, and the installation and removal of the container 10 to and from the container installation table 20 can be performed smoothly. In order to smoothly install the container 10 on the container installation table 20, a container guide surface 33 is provided. When the container flat bottom 15 engages with the mortar-shaped container guide surface 33 with a widened upper surface, the container flat bottom 15 slides on the mortar-shaped surface of the container flat bottom 15 and is smoothly guided to the container installation side surface 32.

[0029] Figure 2 is a perspective view of the container installation device of FIG. 1. The container installation device of the present embodiment is not limited to FIG. 2, but the upper plate 21 and the bottom plate 23 are rectangular, and the container installation parts 30 and the container insertion holes 25 are provided, for example, in 6 rows × 8 columns = 48 pieces. Also, although not particularly limited, the support columns 22 are provided at a total of 5 positions near the four corners and the center of the rectangular shape. In this way, a plurality of containers 10 can be installed on the container installation table 20 in a matrix arrangement, and as will be described later, the rotation of the container bodies 11 of the plurality of containers 10 can be prevented. Further, on the bottom plate 23, a blade plate fixing groove 35 is provided linearly across the plurality of container installation parts in each row. By providing the blade plate 40 in the blade plate fixing groove 35 so as to protrude toward the container flat bottom 15 as the bottom of the container 10 as described later, the rotation of each container body 11 is prevented.

[0030] FIG. 3A is a perspective view of the container of the first example, FIG. 3B is a perspective view of the bottom of the first example, and FIG. 3C is a perspective view of the bottom of the first example from another angle. Since the container 10 of the first example is an example of a transparent container, the specimen stored inside can be visually observed from the outside. In addition, a scale is provided so that the internal volume can be measured when storing a liquid. In the container 10 of the first example, the cap 12, which is a screw cap provided with a female screw, is screwed onto the male screw provided at the opening of the bottomed cylindrical container body 11, so that it can be sealed.

[0031] A cylindrical container flat bottom 15 is provided at the bottom of the container body 11. In the container of the first example, since the bottom of the container body 11 is flat, the container body 11 can stand on its own. The bottom of the portion for storing the contents of the container body 11 reaches a position closer to the cap 12 than the container flat bottom 15, and the shape of the bottom of the portion for storing the contents is a downwardly convex mortar shape.

[0032] Since the container 10 is for storing a specimen, for example, it needs to be disposable. Therefore, a resin material is used as the material of the container 10 in consideration of processability, convenience, cost, etc. Examples of the material of the container 10 include PP (polypropylene, Rockwell hardness about 90, non-reinforced R80-102, talc 10-40% and M85-110), PE (polyethylene, Rockwell hardness about R56, Shore D60-70 (converted to R46-52), high density and Shore D66-73 (converted to R50-55)), PET (polyethylene terephthalate, Rockwell hardness about 125, non-reinforced M94-101, glass F30% and M90-100), PTFE (Teflon (registered trademark), Rockwell hardness Shore D55 (complete and R41), D50-65 (converted to R37-49)), AS (acrylonitrile styrene Rockwell hardness R83), PMMA (acrylic, Rockwell hardness M100, general use M68-105, cast sheet M80-100), PCTA (saturated polyester resin, R80), etc. Among these, in particular, PP or PE is frequently used.

[0033] The type of resin used as the material for the container 10 is not limited to the above-mentioned ones. For example, super engineering plastics such as PEEK (polyether ether ketone, Rockwell hardness 99 - 107), PCTFE (polychlorotrifluoroethylene, Rockwell hardness 75 - 95), PAR (polyarylate, Rockwell hardness 120 - 125), PVDF (polyvinylidene fluoride, Rockwell hardness 93 - 116) can be used. Also, engineering plastics such as PA (polyamide, Rockwell hardness 119), modified PPE (modified polyphenylene ether, Rockwell hardness 118 - 120), AS (acrylonitrile - styrene, Rockwell hardness 83) can be used. Further, general - purpose plastics such as ABS (acrylonitrile, butadiene, styrene copolymer synthetic resin, Rockwell hardness 85 - 120), thermoplastic resins such as Unilate (Rockwell hardness 120), and thermosetting resins such as UP (unsaturated polyester, Rockwell hardness 95 - 110) can also be used. Depending on the use and specifications of the container 10, a resin material with suitable characteristics is selected. The hardness of the resin material used as the material for the container 10 has a lower limit of about 40 and an upper limit of about 125 in Rockwell hardness R1. As an example of a preferable range of the strength of the resin, from the viewpoint of high strength and cost consideration, materials with a Rockwell hardness R2 of about 80 - 120 are often used. Here, the Rockwell hardness mainly refers to the measured value of the R scale by the ASTM D785 test.

[0034] Figure 3D is a perspective view of the container of the second example. In the container 10A of the second example, similar to the container 10 of the first example, a cap 12, which is a screw cap provided with a female screw, is screwed onto a male screw provided at the opening of the bottomed cylindrical container body 11, thereby enabling sealing. However, unlike the first example, the bottom of the container 10A of the second example is provided with a container curved surface bottom 16 having a downward - convex curved surface shape. For this reason, the container 10A of the second example cannot stand on its own.

[0035] At the bottom of the container body 11, a cylindrical container flat bottom 15 is provided. In the container of the first example, since the bottom of the container body 11 is flat, the container body 11 can stand on its own. The bottom of the portion for storing the contents of the container body 11 reaches a position closer to the cap 12 than the container flat bottom 15, and the shape of the bottom of the portion for storing the contents is a downwardly convex mortar shape.

[0036] Figure 4 is a cross-sectional view showing the usage mode of Embodiment 1. The cap gripping mechanism 17 is a mechanism for opening and closing the cap 12 of the container 10. The cap gripping mechanism 17 is not particularly limited, but has three cap gripping claws 18, and by driving the three cap gripping claws with a solenoid, the cap 12 is gripped from the outside. Further, a driving force from a motor is transmitted to the cap gripping claw 18 by a transmission mechanism such as a gear, a belt, or a chain, and the cap 12 is rotationally driven in both directions to open and close the cap 12. In this way, the cap gripping mechanism 17 can grip the cap 12 and rotate in both directions to open and close the cap 12 which is a screw cap.

[0037] The overall configuration of the usage mode includes an operation of gripping and transporting the container 11, an operation of opening and closing the cap 12 of the container 11, and an operation of reading a barcode. In the present embodiment, a specification for opening and closing the cap in a state where the container 11 is installed in the container installation portion 30 is described. The gripping arm for gripping and transporting the container 11 is driven in three three-dimensional axial directions of the X-axis, Y-axis, and Z-axis above the container installation table 20, and can freely grip the container 10 and transport the container 10 to the barcode reader. Further, the gripping arm can also perform an operation of returning to the original position based on the container 10, and can further transport the container 10 to the next process.

[0038] Therefore, in the overall usage mode, for example, the following operations are performed. (1) An operation of gripping the container 10 with the cap 12 tightened and transporting it to the barcode reader, (2) The operation of reading the barcode attached to the container 10 by a barcode reader, (3) The operation of installing the container 10 in the container installation part 30 after barcode reading, (4) The operation of opening the cap with the container body 11 being prevented from rotating in the container installation part 30, (5) The operation of transporting the opened container body 11 to the next process, for example, the specimen extraction process, and (6) The operation of taking out the contents such as the specimen in the specimen extraction process. Note that after this, the taken-out specimen is provided to, for example, the next process.

[0039] The container installation base 20 of the present embodiment can prevent the rotation of a plurality of container bodies 11 at the same time when opening and closing. Therefore, in this usage form, for example, it is also possible to open a plurality of caps 12 at the same time. However, at the site of specimen inspection, in order to avoid the risk of contamination of other specimens, the caps 12 of the containers 10 are often opened one by one. For example, when the container 10 is used to store sputum for coronavirus infection determination, the caps 12 of the containers 10 are often opened one by one to prevent contamination. Also in this case, in the high-speed operation due to the automation of the inspection, since a higher speed than, for example, realizing the opening of one cap in 5 seconds is required for the high-speed opening of the caps 12 of the containers 10, the effect that the present embodiment can prevent the rotation of a plurality of container bodies 11 at the same time when opening and closing is extremely effective also from the viewpoint of the high-speed opening and closing of the caps 12.

[0040] The container installation part 30 is provided with a blade plate 40 so as to protrude from the container installation bottom surface 31 toward the container plane bottom 15. In this way, one or more blade plates 40 protruding toward the container plane bottom 15 which is the bottom surface of the container 10 are provided in the container installation part 30. By engaging the blade plate 40 with the container plane bottom 15 of the container 10, the rotation prevention of the container body 11 when opening and closing the cap 12 of the container 10 with the cap 12 is realized with a simple structure, and moreover, it can also correspond to a plurality of containers 10.

[0041] Moreover, the degree of engagement of the blade plate 40 with the bottom surface 15 of the container plane of the container 10 is set to such an extent that the rotation of the container 10 can be restricted even when an external force in the direction of trying to rotate the container 10 around the axis of the container 10 accompanies the attachment and detachment of the cap 12. Thus, the degree of engagement of the blade plate 40 with the bottom surface 15 of the container plane of the container 10 can be appropriately set. Also, the container 10 is for hermetically storing, for example, a specimen, etc. As will be described later, there is a risk of cracks occurring from scratches when used under conditions of low temperature or frequent temperature changes. Therefore, it is necessary to avoid scratching the bottom surface 15 of the container plane of the container 10 as much as possible. In the present embodiment, since the degree of engagement of the blade plate 40 with the bottom surface 15 of the container plane of the container 10 can be appropriately set, the degree of scratching the container 10 can be suppressed within an appropriate allowable range.

[0042] FIG. 5 is an enlarged perspective view of the container installation part of FIG. 4. In the container installation part 30, a blade plate fixing groove 35 for installing the blade plate 40 is provided linearly. Although not particularly limited, as shown in FIG. 2, the blade plate fixing grooves 35 are provided linearly across the plurality of container installation parts 30 in each row, and a long common blade plate 40 can be provided in the linearly continuous blade plate fixing grooves 35. Thereby, the structure is simpler and it is easier to manufacture than providing short blade plates 40 individually in each container installation part 30.

[0043] FIG. 6 is a cross-sectional view when the container is installed as shown in FIG. 5. A cutting edge is provided at the tip 41 of the blade plate 40 facing the bottom surface 15 of the container 10 in the plane of the container. The blade plate 40 is set so that the cutting edge at the tip 41 of the blade plate slightly bites into the resin material. For example, a commercially available one equivalent to the cutting edge of a utility knife can be used. The specifications of the blade plate 40 are not particularly limited. For example, those with a thickness of 0.38 mm, a height of 9 mm, and a length of 80 mm corresponding to commercially available ones can also be adopted. Although not particularly limited, the angle of the blade tip can be about 15°. Also, the material of the blade plate 40 is not particularly limited. For example, alloy tool steel, stainless steel, etc. corresponding to commercially available ones can be adopted. Further, in the present embodiment, it is linear and provided parallel to the bottom surface 31 for installing the container. This is because the bottom surface 15 in the plane of the container is provided at the bottom of the container 10 illustrated in the present embodiment, so the cutting edge at the tip 41 of the blade plate 40 of the blade plate 40 is also set to be parallel facing the plane of this bottom surface 15 in the plane of the container.

[0044] In FIG. 6, it is shown that the blade plate 40 is not provided at exactly the center of the bottom surface of the container plane 15, but is shifted to the left side in the drawing of FIG. 6. This is because, depending on the clearance conditions between the inner peripheral surface of the container installation side surface 32 and the outer peripheral surface of the bottom of the container body 11, when the blade plate 40 is exactly at the center of the bottom surface of the container plane 15, the stress applied from the container body 11 to the inner peripheral surface of the container installation side surface 32 is balanced, assuming a case where the cutting edge is difficult to bite into the bottom of the container body 11. Therefore, deliberately avoiding the arrangement of the blade plate 40 from the position exactly at the center of the bottom surface of the container plane 15 has the effect of avoiding the balance of the stress applied from the container body 11 to the inner peripheral surface of the container installation side surface 32 in the circumferential direction. However, the present embodiment is not limited to the arrangement of the blade plate 40 in FIG. 6. For example, the arrangement of the blade plate 40 can be set at exactly the center of the bottom surface of the container plane 15, the arrangement of the blade plate 40 in FIG. 6 can be set at a position farther from the center of the bottom surface of the container plane 15, or the arrangement of the blade plate 40 in FIG. 6 can be set at a position closer to the center of the bottom surface of the container plane 15. As long as the cutting edge of the blade plate 40 bites into the bottom surface of the container plane 15, the arrangement of the blade plate 40 is arbitrary.

[0045] The amount by which the cutting edge of the tip of the blade plate 41 bites into the bottom surface of the resin container 10 is set to 0.05 mm to 0.3 mm. The lower limit of 0.005 mm is the limit value that can prevent the rotation of the container body 11, and is determined by analyzing the characteristics of the resin material, the specifications, and the shape of the blade plate 40. The upper limit of 0.3 mm is the allowable range from the perspective of minimizing damage to the bottom of the container 10. Since the container installation part 30 is at a position where the operator can touch it with a finger, it is determined by analyzing a range that can prevent injury even if the operator accidentally touches the blade plate 40.

[0046] Since the amount by which the cutting edge of the blade tip portion 41 bites into the bottom surface 15 of the resin container 10 is set to 0.05 mm to 0.3 mm, the length by which the blade 40 protrudes from the container installation bottom surface 31 can similarly be set to 0.05 mm to 0.3 mm. With a protrusion length of about 0.05 mm to 0.3 mm, even if the operator touches it with a finger, there will be no injury. However, in this embodiment, the length by which the blade 40 protrudes from the container installation bottom surface 31 is not limited only to this range. For example, the length by which the blade 40 protrudes from the container installation bottom surface 31 can also be set to 1 mm. Even when the protrusion length of the blade 40 is 1 mm, since the hardness of the resin material used as the material of the container 10 is about Rockwell hardness 80 to 120 as described above, the amount by which the cutting edge of the blade tip portion 41 bites into the bottom surface 15 of the container 10 can be set to 0.05 mm to 0.3 mm.

[0047] Therefore, the lower limit of the protrusion length of the blade 40 is 0.05 mm, but the upper limit is not limited to 0.3 mm, the upper limit of the biting amount, and it can also be set to 1 mm exceeding this, and can be set in the range up to 3 mm. When the protrusion length of the blade 40 exceeds 3 mm, since a thin blade of about 0.38 mm is used as the blade 40, the mechanical strength of the blade 40 becomes a problem. Taking the protrusion length of the blade 40 of 3 mm as a critical value, when the protrusion length of the blade 40 exceeds 3 mm, in addition to the mechanical strength of the blade 40, the stress applied to the cutting edge of the blade tip portion 41 of the blade 40 also rapidly increases, so various physical property values change rapidly, and the practical product life of the container installation base 20 cannot be ensured.

[0048] The setting of the upper limit value of the protruding length of the blade plate 40 to 3 mm corresponds to the specifications of the containers assumed in this embodiment. Therefore, for containers in different categories with different assumed specifications, the upper limit value of the protruding length is set according to their specifications. For example, since the containers assumed in this embodiment are containers for storing specimens for biochemical tests or microbiological tests, etc., as the capacity of the container 10, a range of approximately 1 ml to 100 ml is assumed, including variations such as 1 ml, 5 ml, 15 ml, 25 ml, 50 ml, etc., and the range of numerical parameters of the container mounting table 20 of this embodiment is set.

[0049] When setting the range of the numerical parameters of the container mounting table 20 of this embodiment, it is adapted to as many arbitrary containers 10 as possible. For this reason, the container mounting table 20 of this embodiment can be adapted to any container as long as it can prevent the rotation associated with the opening and closing of the cap of the container body 11, regardless of the resin type, shape, dimensions, etc. of the container 10. As the shape of the bottom of the container 10, there are self-standing types as shown in FIGS. 3A to 3C, those having a container curved bottom 16 as shown in FIG. 3D, those with a conical container curved bottom 16, those with a deep conical container curved bottom 16, those with a shallow conical container curved bottom 16, those with a changing curved surface shape of the container curved bottom 16, for example, those with a generally conical curved surface shape but also having a flat part at the bottom, etc. The container mounting table 20 of this embodiment can cope with a variety of containers 10.

[0050] In addition, the temperature resistance characteristics of the container 10 satisfy the range of conditions required for a normal container 10 for specimen storage. For example, the temperature conditions during use are set such that the lower limit temperature is about -30°C and the upper limit temperature is about 40°C. Also, the mechanical strength of the container 10 is sufficiently ensured by taking advantage of the characteristics of the resin material. The normal transportation of the container 10, for example, the transportation posture is free, and it is set to withstand vibrations during transportation. As described above, one of the reasons for setting the upper limit of the penetration amount of the cutting edge to 3 mm is that considering the use of the container 10 at a low temperature of about -30°C and the use with temperature changes, if a large scratch is made, cracks may occur in the container 10 depending on the temperature conditions and temperature changes. Therefore, the upper limit of the scratch that penetrates the bottom of the container 10 is set to 0.3 mm.

[0051] In the container mounting base 20 of the present embodiment, if the amount by which the cutting edge of the blade tip portion 41 of the blade plate 40 penetrates the bottom of the container 10 is defined as the penetration amount c, the penetration amount c is 0.05 mm ≤ c ≤ 0.3 mm (Equation 1) Since it is set in this way, the rotation of the container body can be surely prevented. Furthermore, in a place where it is not desired to damage the bottom of the container 10 as much as possible, since the penetration amount c is limited by the upper limit value, the degree of damage to the container can be suppressed within an appropriate range.

[0052] Also, in the container mounting base 20 of the present embodiment, the container 10 is made of resin. If the hardness of the resin of the container body 11 of the container 10 is defined as the Rockwell hardness R, the penetration amount c is c = γR + δ (Equation 2) 0.12 ≤ δ1 ≤ 0.7 (Equation 3) -0.005 ≤ γ1 ≤ -0.00059 (Equation 4) It is set so as to satisfy the relational expressions. Thereby, the container mounting base 20 of the present embodiment can set an appropriate penetration amount according to the hardness of the resin for containers of various specifications, for example, even when the resin materials are different. Therefore, it can surely prevent the rotation of the container body for containers of various materials. The basis for specifying such a numerical range is as follows. (1) The range of the Rockwell hardness R of the resin material is 40 ≦ R1 ≦ 125 (Formula 5) wherein. (2) The condition of Formula 1 regarding the indentation amount c. (3) The characteristics of the Rockwell hardness R and the indentation amount c are parameters according to the specifications of the cutting edge of the blade tip portion 41 of the blade plate in addition to the resin material in (1) above, and are approximated as a linear function.

[0053] Incidentally, as an example of a preferable range of the strength of the resin, from the viewpoint of high strength and cost consideration, as the Rockwell hardness R2, 80 ≦ R2 ≦ 120 (Formula 6) When the condition is set as above, Formula 3 and Formula 4 are specified as the ranges of the following Formula 3-2 and Formula 4-2. Note that Formula 2 is common to Formula 3-2 and Formula 4-2. 0.2 ≦ δ2 ≦ 0.7 (Formula 3-2) -0.005 ≦ γ2 ≦ -0.001 (Formula 4-2)

[0054] This conditional expression is based on the numerical parameters within the range of the specifications of the container installation base 20 of the present embodiment, and for various containers 10, the indentation amount c is set in relation to the Rockwell hardness of the resin of the container body 11 so as to appropriately prevent the rotation of the container body 11 when the cap 12 is opened and closed. Further, in this conditional expression, the function of preventing the rotation of the container body 11 when the cap 12 is opened and closed by causing the cutting edge of the blade tip portion 41 of the blade plate 40 in the container installation base 20 of the present embodiment to bite into the bottom of the container body 11 is realized with a very simple configuration. Therefore, it is possible to express the relationship between the indentation amount c and the Rockwell hardness R as a simple linear expression. That is, the simple shape of the bottom of the container body 11, the characteristics within the normal Rockwell hardness range of the resin, and the specifications of the commercially available blade plate 40 have the effect of suppressing the influence of a complex high-dimensional relationship on this conditional expression. Therefore, in the container installation base 20 of the present embodiment, it is possible to set the indentation amount c based on such a conditional expression.

[0055] [Embodiment 2] The container installation device according to Embodiment 2 of the present invention will be described with reference to FIGS. 8 and 9. The same components as those in FIGS. 1 to 7 are denoted by the same reference numerals, and the description thereof will be omitted.

[0056] FIG. 8 is an enlarged perspective view of the container installation part of the container installation device according to Embodiment 2, and FIG. 9 is an enlarged perspective view of the container installation part of FIG. 8. In the container installation table 20A of Embodiment 2, the structure of the blade plate is different from that of Embodiment 1, and a pair of inclined blade plates 50a and 50b are used. Blade plate installation parts 55 extending in the row direction are respectively provided below both sides in the column direction of the container installation bottom surface 31. That is, since the blade plate installation part 55 extends in the row direction in common with a plurality of container installation parts 30A arranged in the row direction, the structure can be simplified and the manufacturing can be facilitated. Here, although the blade plate installation part 55 has been described as extending in the row direction in common with a plurality of blade plate installation parts 55 arranged in the row direction, the present embodiment is not limited thereto, and the blade plate installation part 55 may be extended in the column direction in common with a plurality of blade plate installation parts 55 arranged in the column direction. In the blade plate installation part 55, the inclined blade plates 50a and 50b are respectively arranged and fixed to the blade plate fixing base 56. A pair of inclined blade plates 50a and 50b are provided for each blade plate installation part 55, and the rotation of the container body 11 can be prevented when the cap 12 is opened and closed by this pair of inclined blade plates 50a and 50b.

[0057] If the angle formed by the cutting edges of the blade tip portions 51a and 51b of the pair of inclined blade plates 50a and 50b with the plane on which the container installation part 30A is provided, that is, the upper surface of the bottom plate 23, is defined as the angle α, although it is not particularly limited, in the example of FIG. 9, the angle α = 60°. However, in the present embodiment, the angle α is not limited to 60°, and for example, it can be 45°, and it is set under the conditions of the following formula. 0° ≦ α < 90° (Equation 7)

[0058] The minimum value in Equation 7 is α = 0°, and in this case, it substantially coincides with the angle of the cutting edge of Embodiment 1. On the other hand, the maximum value in Equation 7 is limited to α < 90°, and the angle α does not include a right angle. The condition of Equation 7 indicates the condition of pressing the cutting edge against the bottom of the container body 11 at an inclined angle. In the present embodiment, the bottom of the container body 11 is the container flat bottom 15, which is a plane parallel to the container installation bottom surface 31. Therefore, it is easy to set a condition in which the cutting edge easily bites into the bottom of the container body 11.

[0059] In the example of FIG. 9, the shape of the container flat bottom 15 at the bottom of the container body 11 is a cylindrical shape with a flat bottom surface. For this shape, by setting the angle α = 60°, the cutting edges of the respective blade tip portions 51a and 51b of the pair of inclined blade plates 50a and 50b appropriately bite into the bottom of the container body 11 within the range of Equation 1, and the container body 11 can be prevented from rotating when the cap 12 is opened and closed, and the amount of biting into the bottom of the container body 11 can be suppressed within an allowable range. The appropriate setting of the angle α can be appropriately set within the range of Equation 7 according to the shape, dimensions, material of the bottom of the container body 11, and the specifications of the blade plate. For example, even when the shape of the bottom of the container body 11 is the container flat bottom 15 as in the case of FIG. 9, the shape and dimensions may be different. Therefore, it is preferable to appropriately set within the range of Equation 7 according to the specifications of the container body 11. Further, in the present embodiment, even in the case of the container 10A of the second example in FIG. 3D, where the bottom of the container 10A is the container curved bottom 16, by setting the angle α so as to surely correspond to the bottom of the container 10A, it is possible to prevent the main body container 11 from rotating when the cap 12 is opened and closed.

[0060] In Fig. 9, an example is shown in which there are a pair of inclined blade plates 50a and 50b, that is, two blade plates at equal intervals. However, the present embodiment is not limited to this. For example, three or more inclined blade plates 50a and 50b can be provided at equal intervals. For example, a total of four inclined blade plates 50a and 50b can be arranged around the bottom of the container body 11 at 90° intervals. When the number of inclined blade plates 50a and 50b increases, the structures of the container installation part 30A and the blade plate installation part 55 become complicated. Therefore, from the viewpoint of a simple structure, the mode of providing a pair of inclined blade plates 50a and 50b in Fig. 9 is advantageous. Furthermore, in order to simplify the structure, it is also possible to provide only one inclined blade plate 50a in Fig. 9. However, depending on the shape of the bottom of the container body 11, the hardness of the resin, the angle α of the inclined blade plate 50a, etc., with only one inclined blade plate 50a, the cutting edge may not sufficiently bite into the bottom of the container body 11. In such a case, it is preferable to provide two or more inclined blade plates 50a and 50b. From such a viewpoint, for example, in the case of a pair of inclined blade plates 50a and 50b, when the cutting edge does not sufficiently bite into the bottom of the container body 11, the number of arranged inclined blade plates 50a and 50b can be increased, for example, by providing three or more inclined blade plates 50a and 50b, so as to prevent the rotation of the container body 11 accompanying the opening and closing of the cap 12.

[0061] In Fig. 9, it is drawn as if there is a gap between the container flat bottom 15 and the container installation bottom surface 31. However, this is for convenience of explanation and depicts an extreme gap. In the actual container installation base 20A, as is clear from the relationship of Equation 1, the gap between the container flat bottom 15 and the container installation bottom surface 31 is extremely small. In an extreme example, depending on the setting, it is also possible to arrange the container flat bottom 15 and the container installation bottom surface 31 to be in contact with each other. However, since the present embodiment aims to surely prevent the rotation of the container body 11 accompanying the opening and closing of the cap 12 by allowing the cutting edge to sufficiently bite into the bottom of the container body 11, it is desirable to set a very small gap between the container flat bottom 15 and the container installation bottom surface 31.

[0062] Also, in Fig. 9, an example is shown where the outer diameter of the bottom surface 31 for installing the container is slightly larger than the inner diameter of the cylindrical shape of the bottom surface 15 of the container plane. However, the present embodiment is not limited to Fig. 9, and it is also possible to set the outer diameter of the bottom surface 31 for installing the container to be larger than the inner diameter of the cylindrical shape of the bottom surface 15 of the container plane. In this case, there is an advantage that the bottom surface 31 for installing the container can be stably installed on the bottom surface 15 of the container plane. On the other hand, in an extreme case, it is also possible to set the outer diameter of the bottom surface 31 for installing the container to be smaller than the inner diameter of the cylindrical shape of the bottom surface 15 of the container plane. In this case, there is an advantage that the cutting edge can easily bite into the bottom of the container body 11 sufficiently.

[0063] In the container installation base 20A of the present embodiment, when the angle formed by the portion where the cutting edges of the blade tip portions 51a and 51b of the pair of inclined blade plates 50a and 50b bite into the bottom of the container 10 and the plane where the container installation portion 30A is provided, that is, the upper surface of the bottom plate 23, is defined as the angle α, the angle α is set to satisfy the above formula 7. Thereby, in the container installation base 20A of the present embodiment, it is possible to surely prevent the rotation of the container body with respect to containers 10 of various specifications. For example, by setting the angle α according to the shape of the bottom of the container 10, it is possible to surely prevent the rotation of the container body whether the bottom of the container is flat or curved. The appropriate setting of the angle α can be appropriately set within the range of formula 7 according to the shape, dimensions, material of the bottom of the container body 11, and the specifications of the blade plate. For example, even when the bottom of the container body 11 is the bottom surface 15 of the container plane as in the case of Fig. 9, since the shape and dimensions may be different, it is preferable to appropriately set within the range of formula 7 according to the specifications of the container body 11.

[0064] [Embodiment 3] The container installation device according to Embodiment 3 of the present invention will be described with reference to Figs. 10 and 11. The same reference numerals are used for the same configurations as in Figs. 1 to 9, and the description thereof will be omitted.

[0065] FIG. 10 is an enlarged cross-sectional view of the container installation device according to Embodiment 3, and FIG. 11 is an enlarged perspective view of the container installation portion of FIG. 10. In the present embodiment, an aspect of the container installation table 20B that prevents rotation when the cap 12 is opened and closed for the container 10A of the second example will be described. In the container installation portion 30B, a container installation side surface 32 and a mortar-shaped container guide surface 33 are provided above the container installation side surface 32. Below the container installation portion 30B, a long blade plate installation portion 65 that extends in common across a plurality of container installation portions 30B arranged in the row direction is provided. By extending the blade plate installation portion 65 in common across a plurality of container installation portions 30B arranged in the row direction, the structures of the container installation portion 30B and the blade plate installation portion 65 can be simplified and it can be made easy to manufacture.

[0066] In the blade plate installation portion 65, a pair of inclined blade plates 60a and 60b are provided so as to face each other in the column direction with the container curved bottom portion 16, which is the bottom of the container body 11, interposed therebetween. When the angle formed by the portion of the cutting edges of the blade tip portions 61a and 61b of the pair of inclined blade plates 60a and 60b that bite into the bottom of the container 10A and the plane on which the container installation portion 30B is provided, that is, the upper surface of the bottom plate 23, is defined as the angle α, the angle α is set so as to satisfy the above formula 7. The inclined blade plates 60a and 60b are fixed to the blade plate installation portion 65 at the angle α by a blade plate fixing portion 66.

[0067] In Fig. 10, although one location is illustrated as a reference sign for the blade plate fixing portion 66, this is for convenience of explanation. Actually, for example, after fixing the lower portions of the inclined blade plates 60a and 60b as the blade plate fixing portion 66 as shown in Fig. 10, it is desirable to also fix the upper portions to the inner wall of the blade plate installation portion 65. Here, an example in which the blade plate installation portion 65 extends commonly across a plurality of container installation portions 30B arranged in the row direction has been described, but the present embodiment is not limited to this. For example, it may extend commonly across a plurality of container installation portions 30B arranged in the column direction. In the example of Fig. 10, the angles α of the inclined blade plates 60a and 60b are illustrated such that the angle α = 45°, but in the present embodiment, the angle α is not limited to this. The angle α can be appropriately set within the range satisfying Equation 7, for example, according to the shape of the bottom of the container 10, so that rotation of the container body can be surely prevented whether the bottom of the container is flat or curved. An appropriate setting of the angle α can be appropriately set within the range of Equation 7 according to the shape, dimensions, material of the bottom of the container body 11, and the specifications of the blade plate. For example, even when the bottom of the container body 11 is the container flat bottom 15 as in the case of Fig. 9, since the shape and dimensions may be different, it is preferable to appropriately set within the range of Equation 7 according to the specifications of the container body 11.

[0068] In Fig. 11, an example in which there is a pair of inclined blade plates 60a and 60b, that is, two at equal intervals, is shown, but the present embodiment is not limited to this. For example, three or more inclined blade plates 50a and 50b can be provided at equal intervals. For example, similar to the case of Embodiment 2, a total of four inclined blade plates 60a and 60b can be arranged around the bottom of the container body 11 at 90° intervals. When the number of inclined blade plates 60a and 60b increases, the structures of the container installation portion 30B and the blade plate installation portion 65 become complicated. Therefore, from the viewpoint of a simple structure, the aspect of providing a pair of inclined blade plates 60a and 60b in Fig. 11 is advantageous.

[0069] In Embodiments 1 and 2, as described by explaining that only one blade plate is provided for each container installation portion 30, it is also possible in this embodiment to minimize the number of blade plate tip portions 61a and 61b as much as possible. When the cutting edge is fully engaged with the bottom surface 16 of the container curved surface, for example, when the shape of the bottom surface 16 of the container curved surface is along the cutting edge, or when the hardness of the resin of the container body 11 is low and the cutting edge is easily engaged, etc., there may be a case where only one inclined blade plate 60a can be provided for each container installation portion 30B.

[0070] However, in this embodiment, since the cutting edges of the blade plate tip portions 61a and 61b of the inclined blade plates 60a and 60b and the bottom surface 16 of the container curved surface may be in a point contact state or a state close to point contact, there is a possibility that the cutting edge may not fully engage with the bottom surface 16 of the container. Therefore, it is desirable that the number of the inclined blade plates 60a and 60b be at least two or more for each container installation portion 30B.

[0071] Depending on the shape of the bottom of the container body 11, the hardness of the resin, the angle α of the inclined blade plate 50a, etc., the cutting edge may not fully engage with the bottom surface 16 of the container curved surface with a pair of inclined blade plates 60a and 60B. In such a case, by increasing the number of arranged inclined blade plates 60a and 60B, the rotation of the container body 11 accompanying the opening and closing of the cap 12 can be prevented. As a further measure, by satisfying the condition of Equation 8 described later, the cutting edge can be set to fully engage.

[0072] According to the container installation base 20B of this embodiment, in the vertical plane including the axis of the container 10A installed in the container installation portion 30B, if the angle formed by the tangent line of the portion where the bottom surface 16 of the container curved surface, which is the bottom of the container 10A, engages with the cutting edges 60a and 60b and the plane where the container installation portion 30B is provided, that is, the upper surface of the bottom plate 23, is β, the relational expression between the angle α and the angle β is -30° ≦ α - β ≦ 30° (Equation 8) It is set so as to achieve this. Thus, according to the container installation base 20B of the present embodiment, it is possible to surely prevent the rotation of the container body with respect to containers 10 of various specifications. For example, by setting the angle α according to the shape of the bottom of the container 10, even when the bottom of the container 10 is flat or when the bottom of the container 10 is curved, it is possible to surely prevent the rotation of the container body.

[0073] In particular, when the container 10 is the container 10A of the second example as shown in FIG. 3D, the bottom becomes the container curved surface bottom 16, and there is a possibility that the curved surface and the cutting edge of the blade plate 23 are in a point contact state or a state close to the point contact state. Therefore, by setting the range so that the angle (angle β) of the tangent line at the portion where the cutting edge of the blade plate 23 bites into the curved surface when the bottom is the container curved surface bottom 16 follows the angle (angle α) of the cutting edge of the blade plate 23, in the portion where the cutting edge of the blade plate 23 bites into the curved surface of the bottom of the container 10A, the condition for maintaining a state close to line contact between the curved surface of the bottom of the container 10A and the cutting edge of the blade plate 23 is set as in the above formula 8. Thereby, it becomes easier for the cutting edge of the blade plate 23 to bite into the bottom of the container 10A, and an appropriate biting amount c can be ensured within the range of the above formula 1. For the setting of the conditions of formula 8, by analyzing in consideration of the shape of the container bottom, the material of the container, for example, the range of the Rockwell hardness R of the resin, the specifications of the inclined blade plates 60a, 60b, etc., critical conditions as in the above formula 8 are found. Within the range of the conditions of the above formula 8, it is easy to make the cutting edge of the blade plate 23 bite into the bottom of the container 10A and to appropriately ensure the biting amount c within the range of the above formula 1. However, if α - β exceeds ±30°, the biting amount suddenly becomes insufficient and the conditions of the above formula 1 deteriorate. Therefore, by satisfying the critical conditional formula according to formula 8, it is possible to achieve a special effect that the rotation of the container body accompanying the opening and closing of the cap 12 can be surely prevented also with respect to containers 10 of various specifications, for example, the container 10A having the container curved surface bottom 16.

[0074] As described above, the container installation device according to the embodiment of the present invention has been explained. However, the above embodiment is an example of a container installation device for embodying the technical idea of the present invention, and does not specify the present invention thereto. It can be equally applied to other embodiments such as modified examples of each embodiment and combinations of each embodiment.

[0075] As the prior art, providing a rotation prevention member around the container body 11 in the container 10 has been described. However, in the present embodiment, it is possible to provide a container installation base 20 that can prevent the rotation of the container body 11 when the cap 12 is opened and closed for various containers 11 regardless of the specifications of the container 11. There are variously specified containers among the commercially available containers 10. For example, even for the container 10 with a rotation prevention member exemplified in the prior art, as long as the rotation prevention member does not prevent the installation of the container body 11 on the container installation portion 30, the container installation base 20 of the present embodiment can be applied to any container 10 including the prior art container 10.

[0076] Regarding FIG. 4, it has been exemplified that the cap gripping mechanism 17 can grip the cap 12 by having three cap gripping claws 18. However, the structure of this cap gripping mechanism 17 is shown as an example of a means for opening and closing the cap 12, and does not limit the present embodiment. In the present embodiment, as long as the cap 12 can be opened and closed, any cap opening and closing means can be applied. For example, as the cap opening and closing means, those using the cap gripping claws 18, having various configurations where the shape and number of the cap gripping claws 18 are not limited, creating a cap holder corresponding to the shape of the cap 12 and opening and closing the cap 12 using the dedicated cap holder, inserting a nozzle into the inner peripheral side of the cap 12 to open and close the cap 12, etc., various means can be adopted.

[0077] Although an example has been given in which a linear cutting edge is provided along the longitudinal direction on the blade tip portion 41 of the blade plate 40, the structure of the blade plate 40 in the present embodiment is not limited thereto. The structure, shape, and dimensions of the blade tip portion 41 can be arbitrary as long as the blade tip portion 41 can prevent the container body 11 from rotating when the cap 12 is opened and closed by biting into the bottom of the container body 11. For example, those in which the cutting edge is not linear, those in which the cutting edge is curved, those in which the cutting edge is provided discontinuously, those in which the cutting edge is serrated, those which are not cutting edges but are, for example, needle-shaped, etc. Various types of blade plates 40 can be adopted.

[0078] Regarding FIG. 5, a linear cutting edge has been exemplified as the cutting edge of the blade tip portion 41 of the blade plate 40, but the present embodiment is not limited thereto. For example, those in which the cutting edge is curved, those in which the cutting edge has a shape corresponding to the bottom shape of the main body container 11, those in which not only the cutting edge but also the blade plate 40 and / or the blade tip portion 41 are on a curve, etc. As long as the blade tip portion 41 can prevent the container body 11 from rotating when the cap 12 is opened and closed by biting into the bottom of the container body 11, the structure of the blade plate 40 can be arbitrary. The same also applies to FIGS. 9 and 10.

[0079] Although the blade plate 40 has been described as always protruding from the container installation portion 30, the present embodiment is not limited thereto. For example, the blade plate 40 can be made movable, and when the container 10 is not installed, a mechanism for moving the blade plate 40 to the storage position can also be adopted.
