Description

Crushing equipment

[0001] The present invention relates to a homogenizer used for analysis and other purposes, and also to a lid member for a container holder attached to the homogenizer.

[0002] A homogenizer is known that holds a homogenizer container and vibrates it strongly to break down the material inside the container into small pieces. Although homogenizers are sometimes called grinders, the two are essentially the same. Homogenizers can be used for homogenization (pulverization) methods such as ball mill homogenization (pulverization) and bead mill homogenization (pulverization), and are widely used for analytical and other applications. For example, as a preprocessing step for obtaining genetic information, specimens such as cells or animal or plant tissues (the material to be homogenized) are enclosed in a homogenizer container along with a homogenizer medium (solid material) and then attached to the homogenizer. The tissue (the material to be homogenized) may also be enclosed in a homogenizer container along with a homogenizer medium (solid material) and a liquid. Homogenizers are also used for freeze-pulverization, which freezes and pulverizes soft materials such as rubber and resin, as well as foods containing water and oil. Homogenizers are also used to crush rocks, coffee beans, and other materials. When crushing rocks, the rocks are placed in a crushing container together with crushing media (solid matter) and then attached to a crushing device. No liquid is used. The crushing container is then vigorously shaken in the crushing device, and tissues and other materials are crushed by the crushing media.

[0003] Many crushing devices have a container holding member, which has a container housing section for housing a crushing container. The container housing section is a space for housing the crushing container. One type of crushing device has a structure in which the container holding member has multiple container housing sections, and crushing containers are placed one by one in each container housing section, and a lid is attached to each container housing section to seal the container housing section. In this type of crushing device, a pair of male and female threads are formed on the container housing section and the lid, and the lid is placed over the opening of the container housing section and turned by hand to screw the lid into the opening of the container housing section.

[0005] In the crushing device described above, crushing containers are placed one by one into the multiple container storage sections of the container holding member, and the container storage sections are covered one by one. That is, lids are placed on the multiple container storage sections, and the lids are turned by hand one by one to close the container storage sections. After crushing is completed, the lids of the container storage sections are removed one by one. That is, the lids are turned by hand one by one to remove the lids, and the container storage sections are opened.

[0006] However, this task requires a lot of force, and improvements are desired. Specifically, the container holding member is provided with multiple container housings, and the container housings are closely spaced. Therefore, the lids are closely spaced, making it difficult to grasp the lids with fingers. Furthermore, because the container holding member is subjected to intense vibration, the inner wall of the container housing must be in close contact with the crushing container, and the lid must be tightened quite tightly. Therefore, considerable force is required both to tighten and to open the lid. In other words, with conventional crushing devices, the lid is difficult to grasp by hand, and considerable force is required to attach and remove it. Furthermore, while it is desirable for the lid to be tightened with a predetermined torque, conventional technologies have no way of doing this other than relying on the operator's experience and intuition.

[0007] The present invention solves the above-mentioned problems of the prior art and provides a crushing device having a cover member that is easy to tighten and open.

[0010] In the above aspect, it is preferable that the engaging portion is provided on the top surface of the cover member.

[0011] According to this aspect, a tool can be engaged from above the lid. For example, if a container holding member has multiple container storage sections, the container storage sections are spaced closely together. Therefore, the sides of the lid members of adjacent container holding members are close to each other, making it difficult to attach a tool to the side of the lid member. In contrast, the top side of the lid member is open. In the crushing device of this aspect, an engagement section for engaging a tool is provided on the top surface of the lid member, making it easy to attach a tool.

[0035] A crushing device 1 according to an embodiment of the present invention will be described below. The invention described in the claims is not limited to the following embodiment. First, an overview of the crushing device 1 will be described. As shown in FIG. 1 , the crushing device 1 according to this embodiment has a container holding member 3 and a vibration means 5 arranged inside a box-shaped outer casing member 2. In this embodiment, the outer casing member 2 has a main body member 7 and a lid member 8. The main body member 7 has a double structure, with the lower level functioning as a machine chamber 12. The upper level of the main body member 7 is open, forming a work space 13. As shown in FIG. 1 , the work space 13 is opened by opening the lid member 8.

[0036] A number of container housing members 10, 11 are attached to the container holding member 3. As shown in FIGS. 4 and 5, the container housing members 10, 11 are hollow, forming a container housing section 61 for housing a crushing container 15. As shown in FIGS. 4 and 5, the crushing container 15 is built into the container housing members 10, 11. That is, the crushing container 15 is housed in the container housing section 61 within the container housing members 10, 11. As shown in FIG. 5, the crushing container 15 contains a material to be crushed 100, a solid material 101, and a liquid 102. The solid material 101 is made of ceramic such as zirconia, natural stone, or metal such as stainless steel, and is a hard, wear-resistant material. The liquid 102 is, for example, a liquid that elutes genetic material.

[0037] The crushing device 1 has a known vibration means 5. The vibration means 5 is composed of a motor 17 provided in the machine room 12, a rotating shaft 21 rotated by the motor 17, an eccentric shaft (not shown), a rotation prevention member, and a holding member fixing part 25. The vibration means 5 has an eccentric shaft (not shown) mounted on the rotating shaft 21 so as to be rotatable relative to the rotating shaft 21, and a holding member fixing part 25 attached to the eccentric shaft. The rotation prevention member (not shown) is, for example, a magnet, and prevents rotation of the holding member fixing part 25 by magnetic force.

[0038] The container holding member 3 is attached to the holding member fixing portion 25 of the vibration means 5. When the motor 17 rotates, the holding member fixing portion 25 oscillates due to the action of the eccentric shaft. Meanwhile, the rotation of the holding member fixing portion 25 is prevented by the rotation prevention member. As a result, the holding member fixing portion 25 and the container holding member 3 attached thereto vibrate up and down in a trajectory that forms the figure "8." Therefore, the object to be crushed 100 repeatedly collides with the solid matter 101 and is crushed into small pieces.

[0039] Next, the characteristic configuration of the crushing device 1 of this embodiment will be described. The container holding member 3 employed in the crushing device 1 of this embodiment is disk-shaped and has a mounting hole 30 formed in its center. The mounting hole 30 has an irregular shape composed of straight and curved lines and is shaped to be engageable with the holding member fixing portion 25. The container holding member 3 has multiple through holes 31 ( FIG. 5 ) arranged in an annular shape. Container housing members 10, 11 are attached to the through holes 31. In this embodiment, the small container housing member 10 and the large container housing member 11 are arranged in an annular shape surrounding the mounting hole 30. That is, four large container housing members 11 are attached at diagonal positions, and two small container housing members 10 are arranged between adjacent large container housing members 11. As described above, the container housing members 10, 11 form the container housing portion 61 that houses the crushing container 15, and therefore the container holding member 3 has multiple container housing portions 61.

[0040] As shown in Figures 3, 4, and 5, the small-container housing member 10 is composed of a main body member 35, a lid member 37, and an elastic member 38. The main body member 35 has a flange portion 40 attached to a cylindrical portion 33. The cylindrical portion 33 is a hollow cylindrical portion that is closed at the bottom and open at the top. The cylindrical portion 33 has a deep recess downward based on the mounting position. The flange portion 40 is a substantially rectangular plate-like member, and has four mounting holes 41. A seat portion 43 is provided on the top surface of the flange portion 40 around the periphery of the cylindrical portion 33. An external thread 45 is provided near the opening of the cylindrical portion 33.

[0041] The lid member 37 is a cylindrical member with a closed top end and an open bottom end. The lid member 37 has a circular top surface 50 and side walls 51 hanging down from the periphery of the top surface. The lid member 37 has a deep recessed portion at the top based on the mounting position. An internal thread 52 is formed on the inner periphery of the lid member 37.

[0042] The lid member 37 employed in this embodiment has an engaging portion 53 on the top surface 50. The engaging portion 53 is a wall-like protrusion having a linear planar shape that stands vertically from the top surface 50. In the lid member 37 of the small-container storage member 10, the engaging portion 53 is molded integrally with the top surface 50.

[0043] The elastic member 38 is an O-ring. The small-container housing member 10 has the elastic member 38 disposed in the seat portion 43 of the flange 40 of the main body member 35 so as to surround the periphery of the cylindrical portion 33, and the lid member 37 attached to the main body member 35. The space formed by the recess of the main body member 35 and the recess of the lid member 37 functions as a container housing portion 61 that houses a crushing container. In this embodiment, the container housing portion 61 is sealed by attaching the lid member 37.

[0044] Next, the large container storage member 11 will be described. The structure of the large container storage member 11 is basically the same as that of the small container storage member 10 described above, but it can be said to be a scaled-up version. That is, as shown in FIG. 7 , the large container storage member 11, like the small container storage member 10, is composed of a main body member 35, a lid member 65, and an elastic member 38. However, all of these are larger than those of the small container storage member 10. The main body member 35 has a flange portion 40 attached to a cylindrical portion 33. The cylindrical portion 33 is a hollow cylindrical portion with a closed lower end and an open upper end. The flange portion 40 is a roughly rectangular plate and has four mounting holes 41. A seat portion 43 is provided on the upper surface of the flange 40 around the periphery of the cylindrical portion 33. An external thread 45 is provided near the opening of the cylindrical portion 33.

[0045] The lid member 65 of the large-container housing member 11 has an engaging member 68 adhered to a lid main body 67. The lid main body 67 of the lid member 65 is a cylindrical member with a closed upper end and an open lower end. The lid member 65 has a circular top surface 70 and a side wall 71 hanging down from the periphery of the top surface. An internal thread 72 is formed on the inner periphery of the lid main body 67.

[0046] The engaging member 68 has a circular flange portion 75 and an engaging portion 76 protruding from the flange portion 75. The engaging portion 76 is a wall-like protrusion having a linear planar shape that stands perpendicularly from the flange portion 75. In the lid member 65 of the large-container storage member 11, the flange portion 75 of the engaging member 68 is adhered to the top surface 70 of the lid main body 67 with an adhesive.

[0047] The large-sized container housing member 11 has an elastic member 38 disposed around the cylindrical portion 33 on the seat portion 43 of the flange 40 of the main body member 35, and a lid member 65 attached to the main body member 35. The space formed by the recess of the main body member 35 and the recess of the lid member 65 is a container housing portion 61 that houses a crushing container. In this embodiment, the container housing portion 61 is sealed by attaching the lid member 65.

[0048] The small container storage member 10 and the large container storage member 11 are attached to the container holding member 3. That is, the main body member 35 is inserted into the through-hole 31 (FIG. 5) of the container holding member 3, the flange portion 40 of the main body member 35 is brought into contact with the upper surface of the container holding member 3, and screws (not shown) are inserted through the mounting holes 41 and the mounting holes (not shown) of the container holding member 3 to attach the small container storage member 10 and the large container storage member 11 to the container holding member 3.

[0049] In the crushing device 1 of this embodiment, as described above, the crushing container 15 is built into the container housing members 10, 11. That is, the crushing container 15 is inserted into the recess of the main body member 35 of the container housing members 10, 11, and the lid members 37, 65 are attached to close the container housing portion 61. After crushing is completed, the lid members 37, 65 are removed to open the container housing portion 61, and the crushing container 15 is removed. Here, in this embodiment, a tool can be used to attach and remove the lid members 37, 65, as shown in FIG. 6 .

[0050] When attaching the cover members 37, 65, it is desirable to use a tool that can tell the tightening torque value. Examples of tools with this function include a torque wrench and a torque driver. Furthermore, it is recommended to tighten the cover members 37, 65 using an idle torque wrench or an idle torque driver that has an idle function.

[0051] For example, a hand tool 200 having a ratchet function and a torque limiting function, as shown in Figure 6, can be used. The hand tool 200 is a tool widely known as a free-wheeling torque wrench, and has a main body 201 and an interchangeable socket 202. The main body 201 has an arm 205 and an engaging protrusion 203. The main body 201 has a torque setting knob 207 and a rotation direction determining knob (not shown) at its end. The engaging protrusion 203 rotates with the rotation of the arm 205, but will freewheel when the torque exceeds a set value.

[0052] The replacement socket 202 is an axial member having a main body side engaging portion 206 on one end face that engages with the engaging protrusion 203 of the hand tool 200, and a lid side engaging portion 210 on the other end face that engages with the engaging portion 53 of the lid member 37, 65.

[0053] In this embodiment, the replacement socket 202 is attached to the main body 201 as shown in FIG. 6( b), and the cover-side engaging portion 210 of the replacement socket 202 is engaged with the engaging portions 53, 76 of the cover members 37, 65 as shown in FIG. 6( c). The engaging portions 53, 76 of the cover members 37, 65 are both provided on the top surfaces of the cover members 37, 65. Since there are no obstructing members on the top surfaces of the cover members 37, 65, the cover-side engaging portion 210 of the hand tool 200 can be brought close to and engaged with the engaging portions 53, 76 of the cover members 37, 65 as shown in FIG. 6( b). If the large-container housing member 11 gets in the way of rotating the cover member 37 of the small-container housing member 10, it is desirable to interpose an extension member such as a well-known extension rod between the main body 201 and the replacement socket 202.

[0054] The hand tool 200 has a ratchet function, so that when attaching the cover members 37, 65, for example, the arm portion 205 is reciprocated to tighten the cover members 37, 65. Furthermore, when the cover members 37, 65 are tightened and their ends come into contact with the elastic member 38, and the elastic member 38 is appropriately compressed, the tightening torque reaches a certain value. The hand tool 200 employed in this embodiment has a torque limiting function, so that when the cover members 37, 65 are tightened and their ends come into contact with the elastic member 38, and the elastic member 38 is appropriately compressed, the arm portion 205 spins freely, preventing further tightening.

[0055] To remove the cover members 37, 65, the rotation direction of the hand tool 200 is switched, and the cover side engaging portion 210 of the replacement socket 202 is engaged with the engaging portion 53 of the cover members 37, 65, as shown in Figure 6(c), causing the arm portion 205 to reciprocate. In this embodiment, the cover members 37, 65 are rotated using the hand tool 200 rather than being grasped directly with the fingers, so that the cover members 37, 65 can be attached or removed with little force. A power tool can also be used, and using a power tool allows the cover members 37, 65 to be attached or removed more efficiently.

[0056] In an actual crushing device 1, many main body members 35 of the container accommodating members 10, 11 are attached to the container holding member 3, resulting in a crowded environment. Therefore, it is recommended to use a dedicated tool 250 as shown in FIG. 13 . The dedicated tool 250 has an extension member 260 instead of the replacement socket 202. The extension member 260 can be considered a replacement socket with a longer overall length. That is, the dedicated tool 250 has a main body 201 and an extension member 260. The main body 201 is the same as that of the hand tool 200 described above. The extension member 260 has a main body-side engaging portion 206 on one end surface that engages with the engaging protrusion 203 of the main body 201, and a lid-side engaging portion 208 on the other end surface that engages with the engaging portion of the lid member 37, 65. The dedicated tool of this embodiment is compatible with lid members having a rectangular or cubic engaging portion, as described below, and the lid-side engaging portion 208 is a square hole.

[0057] In the above-described embodiments, the engaging portions 53, 76 provided on the cover members 37, 65 are wall-like protrusions with a linear planar shape extending perpendicularly from the top surfaces 50, 70, respectively. However, the present invention is not limited to this configuration. Examples of engaging portions are shown in FIGS. 10 and 11 . While the engaging portions employed in the above-described embodiments are protrusions extending from the top surfaces 50, 70 of the cover members 37, 65, they may also be recessed portions such as the engaging portions 81, 82 shown in FIGS. 10(d) and 10(e). Furthermore, while the engaging portions 53, 76 described above are linear protrusions, they may also be polygonal protrusions such as the engaging portions 77, 82 shown in FIGS. 10(a) and 10(e). The engaging portions 77, 82 shown in FIGS. 10(a) and 10(e) are hexagonal, but may have five or more sides or fewer. They may also be cross-shaped protrusions such as the engaging portion 80 shown in FIG. 10(c). The engaging portions 81 and 83 shown in Figures 10(d) and 10(f) may have a curved base such as an ellipse or a long hole. The engaging portion 78 shown in Figure 10(b) has a wall-like protrusion with a horizontal hole (through hole) 85. The lid member shown in Figure 10(b) has the horizontal hole 85 as the engaging portion, and is rotated by inserting a rod (tool) 86 into the horizontal hole 85.

[0058] The cover member 55 shown in FIG. 11( a) has an engaging portion 56 with a square planar shape. That is, the engaging portion 56 is a rectangular or cubic protrusion with a top surface and four side surfaces. A manual tool (specialized tool 250) having a square-shaped cover-side engaging portion 208 as shown in FIG. 13 is used to rotate the cover member 55. The square-shaped cover-side engaging portion 208 is engaged with the square-shaped engaging portion 56 of the cover member 55. The cover member 57 shown in FIG. 11( b) has a through-hole 85 formed in the engaging portion 56. The cover member 57 shown in FIG. 11( b) can be rotated by inserting a rod (tool) 86 into the through-hole 85. Of course, it can also be rotated using a tool having a square-shaped cover-side engaging portion 208. The cover member 58 shown in FIG. 11( c) has a cover main body 67 and an engaging member 68 molded separately, and the engaging member 68 is later attached to the cover main body 67 by adhesive bonding, welding, or the like. The engaging member 68 has a flange portion 75, and an engaging portion 56 is provided on one surface of the flange portion. The planar shape of the engaging portion 56 is square, and a through hole 85 is provided in the horizontal direction. The cover members 55, 57, and 58 shown in Figure 11 have anti-slip coating on the side surfaces.

[0059] The method for forming the engaging portion is not limited. It may be integrally molded, as in the lid member 37 of the small-container housing member 10, or the lid body 67 and engaging member 68 may be molded separately and then attached later by adhesive bonding, welding, or the like, as in the lid member 65 of the large-container housing member 11. When the lid body 67 and engaging member 68 are molded separately and then attached later by adhesive bonding, welding, or the like, as in the lid member 65 of the large-container housing member 11, it is desirable to use an alignment jig 87 as shown in FIGS. 8 and 9 . The jig 87 is a recessed member that covers the lid body 67 and has an opening 88 on its top surface. The planar shape of the inner periphery of the jig 87 is similar to that of the lid body 67, but its size is slightly larger than that of the lid body 67. The shape of the opening 88 is similar to that of the flange portion 75 of the engaging member 68, but its size is slightly larger than that of the flange portion 75. The center of the opening 88 coincides with the central axis of the jig 87.

[0060] When attaching the engaging member 68 to the lid main body 67, a jig 87 is placed over the lid main body 67. Before or after this process, adhesive is applied to either the flange portion 75 of the engaging member 68 or the lid main body 67, or both. The engaging member 68 is then inserted into the opening 88 of the jig 87 and pressed down with a pressing member (not shown). As a result, the engaging member 68 can be attached to the center of the top surface of the lid main body 67.

[0061] The container holding members 3 employed in this embodiment include a mixture of container holding members 10, 11 of different sizes. When container holding members 10, 11 of different sizes are mixed, it is desirable to arrange container holding members 10, 11 of equal size at diagonal positions, taking weight balance into consideration, as in this embodiment. Furthermore, the crushing device 1 of this embodiment can crush various objects to be crushed by replacing the container holding members 3. That is, there are container holding members of various sizes, such as large, medium, small, extra large, and extra small, and container holding members 3 with these attached in any desired proportion are prepared. Then, the container holding members 3 are replaced and used depending on the size and properties of the object to be crushed.

[0062] FIG. 12 shows modified examples of the engaging member. Each engaging member has a flange portion 75 and an engaging portion. Each engaging member shown in FIG. 12 has an engaging portion 77 and the like provided on one side of the flange portion 75. That is, the engaging portion 77 and the like protrude from the flange portion 75. An adhesive layer 90 and a release paper 91 are attached to the other surface of the flange portion 75. The shape of the flange portion 75 is arbitrary, and may be a rectangle as shown in FIG. 12( e). The flange portion may also be another polygon or an ellipse. The shape of the engaging portion is the same as the example shown in FIG. 10, and the same parts as in FIG. 10 are assigned the same numbers and will not be described again.

[0063] The crushing device described above vibrates the container holding member 3 in the vertical direction along a locus that forms an "8," but the vibration pattern is not limited thereto. The container holding member 3 may be simply vibrated in the vertical direction, or may be vibrated in the horizontal direction or diagonal direction. Furthermore, the vibration pattern may be a mixture of horizontal, diagonal, and vertical components. It may also include rotation. The vibration direction may change over time.

[0064] Although the engaging members described above were all developed to be attached to the lid of a crushing device, they may also be attached to the lids of other devices. For example, as shown in FIG. 14( a), an engaging member 68 may be attached to a lid 301 attached to a jar 300 of jam or the like, as shown in FIG. 14( b), and a tool may be engaged with the engaging portion to open the lid 301, as shown in FIG. 14( c). For general-purpose use, it is desirable to pre-apply an adhesive layer 90 to one surface of the flange portion 75. It is desirable that a release paper 91 be attached to the adhesive layer 90. For example, the release paper 91 is peeled off to expose the adhesive layer 90, and the flange is attached to the top surface of the lid 301 of the jar 300. Then, a tool is engaged with the engaging portion and rotated to open the lid. The type of jar to which the lid is attached is not limited. For example, in addition to the above-mentioned food jars of jam, it may also be a chemical jar. The engaging member may also be used for lids without threads, such as lids for tea canisters and cans of black tea leaves.
