Description

Technical Field

[0001] This invention relates to a measuring device for determining the weight of an object. Background Technology

[0002] Traditionally, to separate powdered or granular materials into fixed quantities or to measure the flow rate of materials between processes, metering devices are used, which include a force sensor, a metering container, a load-bearing section that transfers the load to the force sensor, and a suspension member that suspends the metering container above the load-bearing section. In the metering device, the material falls into the metering container, and the load applied to the metering container is measured using a force sensor.

[0003] If the load-bearing section and the measuring container are completely fixed, there is a risk of device malfunction due to the impact load generated when the object is introduced. Therefore, to mitigate this impact load, a scheme allowing a certain amount of oscillation between the load-bearing section and the measuring container has been proposed. On the other hand, since large-amplitude oscillations can affect the measurement results, it is required that the oscillation converge quickly in order to balance measurement accuracy and shorten the measurement time.

[0004] For example, Patent Document 1 discloses a suspension component with ball bearings. This suspension component includes: a first component mounted on a shaft-shaped load-bearing portion, and a second component mounted on the first component and fixed to a measuring container. The first component has a first hole and a second hole, each fitted with a ball bearing. The first component is rotatably mounted on the load-bearing portion by inserting the load-bearing portion into the ball bearing in the first hole. The second component is rotatably mounted on the first component by inserting a rotating shaft located at one end of the second component into the ball bearing in the second hole of the first component. The load-bearing portion and the first hole have horizontally oriented shafts, and the second hole has a horizontally oriented shaft perpendicular to the first hole. Furthermore, the other end of the second component is fixed to the measuring container by bolts.

[0005] According to Patent Document 1, the following effects are achieved: The first component can swing about the axis of the load-bearing part, while the second component, fixed to the measuring container, can swing relative to the first component about an axis perpendicular to the axis of the load-bearing part. Therefore, the swing caused by the impact will quickly converge due to the weight of the measuring container and the object. Through the low-friction ball bearings, the first and second components quickly return to the position where the measuring container is at its lowest point. Thus, it is possible to perform measurement in a short time while improving measurement accuracy.

[0008] Patent Document 1: Japanese Patent Application Publication No. 2013-108825 Summary of the Invention

[0009] -The problem the invention aims to solve-

[0010] Existing technologies cannot adequately meet the requirement of rapidly converging the vibration of the measuring container to achieve high-precision measurement.

[0011] The purpose of this invention is to provide a technology that can shorten the measurement time while achieving high measurement accuracy.

[0012] -Solutions for solving the problem-

[0013] To address the aforementioned problems, the present invention provides the following measuring container.

[0014] The measuring container of the first aspect of the invention includes: a force sensor; a load-bearing portion for transmitting a load to the force sensor; a measuring container for containing a measuring object; a suspension member for suspending the measuring container on the load-bearing portion; a first upper buffer portion, which is an elastic body installed on at least one of the load-bearing portion and the suspension member; a second upper buffer portion, which is an elastic body configured to be aligned with the first upper buffer portion in a first direction; an upper fastening portion for fastening the first upper buffer portion and the second upper buffer portion in the first direction; and a first lower buffer portion, which is installed on... The elastomer of at least one of the metering container and the suspension member; a second lower buffer portion, which is an elastomer configured to be arranged in a second direction different from the first direction from the first lower buffer portion; and a lower fastening portion, which fastens the first lower buffer portion and the second lower buffer portion in the second direction; one of the load-bearing portion or the suspension member is connected to the other by being clamped by the first upper buffer portion and the second upper buffer portion, and one of the metering container or the suspension member is connected to the other by being clamped by the first lower buffer portion and the second lower buffer portion.

[0015] The second aspect of the invention describes a measuring container comprising a force sensor, a load-bearing portion for transmitting load to the force sensor, a measuring container for accommodating the object to be measured, and a suspension member suspending the measuring container from the load-bearing portion. The suspension member has a horizontally oriented lower connecting hole, and the measuring container has a horizontally oriented container hole. Furthermore, the measuring device also includes a lower sleeve-type component having: a lower cylindrical portion, which is an elastic body configured to penetrate the measuring container through the container hole; and a lower flange portion extending radially outward from one end of the lower cylindrical portion, located between the measuring container and the suspension member. The measuring device also includes a lower fastening portion having a lower bolt inserted into the lower cylindrical portion and a lower nut engaged with the lower bolt. The lower bolt has: a lower shaft portion that passes through the lower connecting hole and is inserted into the lower sleeve-type component; and a lower head having a larger diameter than the lower connecting hole, clamping the suspension member and positioned on the side opposite to the lower flange portion. The lower fastening portion is screwed into the lower nut via the lower shaft portion to horizontally fasten the lower cylindrical portion and the lower flange portion. Due to the fastening of the lower fastening portion, the lower cylindrical portion bulges radially outward. The metering container is connected to the suspension member by being sandwiched between the bulging portion of the lower cylindrical portion and the lower flange portion around the container hole.

[0016] -The Effects of the Invention-

[0017] Through the first upper buffer section and the second upper buffer section, or the first lower buffer section and the second lower buffer section, the metering container can displace relative to the load portion within the elastic range of these buffer sections. That is, since it can absorb impact loads on the one hand, and the range of displacement is more limited than before, the swaying caused by displacement is reduced. In addition, the time required for sway decay is shortened by these buffer sections. Therefore, according to the present invention, it is possible to achieve high metering accuracy while reducing the time required for metering. Attached Figure Description

[0027] The following describes an exemplary implementation. In the figures, the x-axis is the horizontal axis, the y-axis is the vertical axis, and the z-axis is the axis perpendicular to the x-axis and y-axis.

[0028] 1. Measuring device 1

[0029] Figure 1 This is a partially exploded perspective view of measuring device 1. Figures 2-4 This diagram shows the suspension member 5 and its surrounding structure that connects the load-bearing unit 3 to the metering container 4 located below it in the metering device 1. Figure 2 It is an exploded 3D diagram. Figure 3 It is a side view. Figure 4 This is the main view. Figure 5 yes Figure 4 An enlarged sectional view of the suspension component 5 and its surrounding area. It should be noted that... Figure 3 In the middle, for ease of explanation, the load section 3 is represented by a dashed line.

[0030] like Figures 1-2 As shown, the metering device 1 of this embodiment includes: a holding frame 11, a force sensor 2, a load-bearing section 3, a metering container 4, a suspension member 5, an upper sleeve-type component 61, a lower sleeve-type component 62, an upper fastening section 71, a lower fastening section 72, a supply door 8, and a discharge door (not shown). By opening and closing the supply door 8, the object is fed from the storage tank into the metering container 4. Furthermore, by opening the discharge door, the fed object is discharged out of the metering container 4. The metering device 1 transmits the load of the metering container 4 containing the object to the force sensor 2, and measures the object based on the output of the force sensor 2.

[0031] The retaining frame 11 has a rear component 12, a front component 13, two support plates 14, two force sensor covers 15, and a control box 16 mounted on the front surface.

[0032] The rear component 12 and the front component 13 are configured to face each other in the z-axis direction and to have their length direction parallel to the x-axis direction. The height (dimension in the y-axis direction) of the rear component 12 and the front component 13 is set such that the bottom of the measuring container 4, held on the holding frame 11, is suspended without contacting the mounting surface of the measuring device 1. The lower parts of the rear component 12 and the front component 13 can also be configured to connect to other devices. Therefore, the mounting surface of the measuring device 1 can be a plane or another device positioned below the measuring device 1. Examples of such other devices include a device for bagging the measured object or a device for processing the measured object.

[0033] The two support plates 14 are flat plate-shaped components arranged opposite each other in the x-axis direction and with their length direction parallel to the z-axis. Each support plate 14 is connected at both ends to the rear component 12 and the front component 13, respectively. That is, the rear component 12, the front component 13, and the two support plates 14 make the retaining frame 11 approximately rectangular in plan view. Two through holes are formed in the support plates 14, namely, a first through hole 14a and a second through hole 14b, arranged in the y-axis direction along the length direction (i.e., the z-axis direction) of the support plate 14. The suspension member 5 passes through the first through hole 14a and the second through hole 14b. The diameters of the first through hole 14a and the second through hole 14b are larger than the diameter of the suspension member 5, allowing the suspension member 5 to move horizontally. It should be noted that the retaining frame 11 may appropriately include ribs to reinforce the support plates 14, corner pieces to fix the components together, bolts and nuts, and other additional structures.

[0034] A force sensor cover 15 is mounted on the support plate 14, covering the force sensor 2 from above and the side. Figure 1 The illustration only shows the force sensor cover 15 located inside the paper in the x-axis direction, and the illustration of the force sensor cover 15 located outside the paper is omitted.

[0035] The control box 16 houses the control devices described later inside it. In addition, its front surface is provided with an input device for receiving instructions and inputs from the user, a display section for displaying measurement results to the user, and so on.

[0036] In this embodiment, the force sensor 2 is a so-called beam type. The force sensor 2 is disposed on the support plate 14 between the two first through holes 14a and the second through hole 14b, such that the length direction of the force sensor 2 is parallel to the length direction (i.e., the z-axis direction) of the support plate 14. Furthermore, the force sensor 2 at its first end ( Figure 3 The left end of the force sensor 2 is fixed to the support plate 14 by bolts. A lower spacer 21 is inserted between the first end of the force sensor 2 and the support plate 14. The force sensor 2 converts the load from the metering container 4 transmitted via the load-bearing part 3 disposed thereon into an electrical signal and outputs it to the control device described later.

[0037] The load-bearing section 3 transmits the load to the force sensor 2. The load-bearing section 3 is a flat plate component disposed on the force sensor 2, such that the length direction of the load-bearing section 3 is parallel to the length direction (i.e., the z-axis direction) of the force sensor 2. Near both ends of the load-bearing section 3, coaxially arranged with the two first through holes 14a and the second through hole 14b of the support plate 14, are first load holes 3a and second load holes 3b penetrating the load-bearing section 3 in the vertical direction. The measuring container 4 is suspended from the load-bearing section 3 by the suspension member 5 at the first load holes 3a and the second load holes 3b. An upper spacer 22 is inserted between the second end of the force sensor 2 and the load-bearing section 3. Other through holes are formed on the load-bearing section 3 at positions corresponding to the upper spacer 22, and the load-bearing section 3 and the upper spacer 22 are fixed to the second end of the force sensor 2 by bolts passing through these through holes.

[0038] Measuring container 4 can temporarily contain measuring objects fed from above. Measuring container 4 has a container body 41, an eave 42, and handles 43. The container body 41 includes two side walls parallel to and opposite to each other on the yz plane, and two side walls parallel to and opposite to each other on the xy plane, and has a generally cuboid shape. The upper part of the container body 41 is open, and the lower part forms a discharge port (not shown). The eave 42 is formed to project obliquely downwards and outwards along the entire circumference of the upper edge of the container body 41. Furthermore, walls extend downwards from the outer edge of the eave 42, parallel to the four side walls of the container body 41. Of these four walls, the two walls parallel to the yz plane form handles 43. In other words, the measuring container 4 has a container body 41 and handles 43 arranged parallel to the two side walls of the container body 41 in the x-axis direction. Each handle 43 has two through holes in the x-axis direction. Each through hole is referred to as a "first container hole" and a "second container hole," and is labeled 43a and 43b, respectively. It should be noted that the measuring container 4 is formed as a whole, namely the container body 41, the eaves 42 and the handle 43.

[0039] In this specification, "integral formation" includes cases where two or more parts are formed into one piece by casting or bending, and cases where two or more parts are formed separately and then integrated by welding, as well as cases formed by combining these methods. In other words, "integral formation" can mean two or more parts "fixed to be inseparable from each other".

[0040] Reference Figure 6 The following section provides an explanation of the suspension component 5. Figure 6 This is a perspective view of the suspension member 5. The suspension member 5 has a cylindrical portion 51, a plate portion 52, and an annular portion (horizontal portion) 53 disposed at the upper end of the cylindrical portion 51 and whose planar direction is horizontal. The hole in the annular portion 53 is called the upper connecting hole, marked 53a. The upper connecting hole 53a and the cylindrical portion 51 are coaxially arranged, and this axis is shown as "A" in the diagram.

[0041] The outer diameter of the annular portion 53 is the same as the outer diameter of the cylindrical portion 51, while the inner diameter of the annular portion 53, i.e., the diameter of the upper connecting hole 53a, is smaller than the inner diameter of the cylindrical portion 51. By having the annular portion 53, the suspension member 5 has an opening at its upper end that is smaller than the inner diameter of the cylindrical portion 51 and connects to the interior of the cylindrical portion 51. The annular portion 53 and the cylindrical portion 51 are integrally formed.

[0042] The plate portion 52 is disposed on the shaft A, parallel to the shaft A, at the lower end of the cylindrical portion 51. The plate portion 52 and the cylindrical portion 51 together form a vertical portion extending in the vertical direction. A lower connecting hole 52a, serving as a through hole, is formed on the plate portion 52. The lower connecting hole 52a is disposed on the shaft A, and the shaft B of the lower connecting hole 52a is orthogonal to the shaft A. Furthermore, the plate portion 52 and the cylindrical portion 51 are integrally formed. That is, the suspension member 5 is integrally formed. Specifically, in this embodiment, the plate portion 52 has a U-shaped cutout 52c with an edge at its upper end, and the lower end of the cylindrical portion 51 is inserted into the cutout 52c. The cylindrical portion 51 and the cutout 52c are fused together.

[0043] Two suspension members 5 are positioned below a load-bearing section 3, such that shaft A coincides with the shafts of the first load hole 3a and the second load hole 3b, respectively. Furthermore, these suspension members 5 are configured such that their respective shafts B coincide with the shafts of the first container hole 43a and the second container hole 43b arranged along the z-axis.

[0044] Reference Figure 5The upper sleeve-type component 61 and the lower sleeve-type component 62 will be described below. The upper sleeve-type component 61 is an elastic body, having an upper cylindrical portion 61a and an upper flange portion 61b extending radially outward from one end of the upper cylindrical portion 61a. That is, in a cross-section parallel to the height direction of the upper cylindrical portion 61a, the upper sleeve-type component 61 has a T-shaped shape. It should be noted that the upper sleeve-type component 61 has a through hole in the height direction of its upper cylindrical portion 61a. Hereinafter, for the upper cylindrical portion 61a and the lower cylindrical portion 62a, "height direction" is not related to the vertical direction, but refers to the height direction of the cylinder (i.e., the direction perpendicular to the radial direction). The upper flange portion 61b is disposed between the load-bearing portion 3 and the annular portion 53 of the suspension member 5, and the upper cylindrical portion 61a is configured to pass through the annular portion 53 in the upper connecting hole 53a. In other words, the height of the upper cylindrical portion 61a is greater than the thickness of the annular portion 53. The upper cylindrical portion 61a is inserted into the upper connecting hole 53a, so that the end of the upper cylindrical portion 61a opposite to the upper flange portion 61b reaches the inside of the annular portion 53, that is, the inside of the cylindrical portion 51.

[0045] The lower sleeve-type component 62 has the same structure as the upper sleeve-type component 61. Specifically, the lower sleeve-type component 62 is an elastic body, having: a lower cylindrical portion 62a; and a lower flange portion 62b disposed at one end of the lower cylindrical portion 62a and extending radially outward from one end of the lower cylindrical portion 62a. Furthermore, the lower flange portion 62b is disposed between the plate portion 52 and the handle 43, and the lower cylindrical portion 62a is configured to penetrate the handle 43 through the first container hole 43a. In other words, the height of the lower cylindrical portion 62a is greater than the thickness of the handle 43, and the lower cylindrical portion 62a is inserted into the first container hole 43a such that the end of the lower cylindrical portion 62a opposite to the lower flange portion 62b reaches the inner side of the handle 43.

[0046] Reference Figure 5 and Figure 7 The upper fastening part 71 and the lower fastening part 72 will be described. Figure 7 This is a cross-sectional view showing the upper fastening part 71 and its surrounding structure. It should be noted that... Figure 5 The washer is omitted from the sectional view.

[0047] The upper fastening part 71 has an upper bolt 711 and an upper nut 712. The upper bolt 711 has an upper head 711a and an upper shaft portion 711b. The upper nut 712 is formed to fit into the upper shaft portion 711b. The upper nut 712 is embedded in the upper cylindrical part 61a near the end opposite to the upper flange portion 61b, such that the inner circumferential surface (i.e., the threaded portion) of the upper nut 712 is exposed from the inner circumferential surface of the upper cylindrical part 61a. In other words, the threaded hole of the upper nut 712 is coaxially configured with the upper cylindrical part 61a of the upper sleeve-type component 61. In addition, the upper head 711a has a diameter larger than the diameter of the first load hole 3a and the second load hole 3b.

[0048] The lower fastening portion 72 has the same structure as the upper fastening portion 71. The lower fastening portion 72 has a lower bolt 721 and a lower nut 722. The lower bolt 721 has a lower head 721a and a lower shaft portion 721b. The lower nut 722 is formed to engage with the lower shaft portion 721b. In the lower cylindrical portion 62a, the lower nut 722 is embedded near the end opposite to the lower flange portion 62b, such that the inner circumferential surface (i.e., the threaded portion) of the lower nut 722 protrudes from the inner circumferential surface of the lower cylindrical portion 62a. In other words, the threaded hole of the lower nut 722 is coaxially configured with the lower cylindrical portion 62a of the lower sleeve-type component 62. Furthermore, the lower head 721a has a diameter larger than the diameter of the lower connecting hole 52a.

[0049] The connection between the suspension component 5 and the metering container 4, as well as the connection between the suspension component 5 and the load-bearing part 3, will be explained.

[0050] like Figures 2-5 As shown, the lower sleeve-type component 62 is configured such that the lower cylindrical portion 62a passes through the handle 43 in the first container hole 43a, and the lower flange portion 62b abuts against the handle 43 from the outside of the handle 43 of the metering container 4 (the side opposite to the container body 41). The suspension member 5 is configured such that the plate portion 52 abuts against the outer side of the lower flange portion 62b, and the lower connecting hole 52a is coaxial with the first container hole 43a, that is, coaxial with the through hole of the lower sleeve-type component 62. The lower shaft portion 721b passes through the lower connecting hole 52a and is inserted into the lower sleeve-type component 62, and screwed into the lower nut 722. The lower head 721a abuts against the outer side of the plate portion 52 around the lower connecting hole 52a. Thus, the lower sleeve-type component 62 is fastened in the x-axis (horizontal) direction by the lower fastening portion 72, and the suspension member 5 is connected to the metering container 4.

[0051] Similarly, in the second container hole 43b, which is aligned with the first container hole 43a in the z-axis direction, and further in the first container hole 43a and the second container hole 43b on the opposite side in the x-axis direction, the suspension member 5 and the measuring container 4 are also connected by the lower fastening part 72. Thus, four suspension members 5 are connected to one measuring container 4.

[0052] Two adjacent suspension members 5 in the z-axis direction are inserted from below into the first through hole 14a and the second through hole 14b, respectively, so that the upper end of the cylindrical part 51 protrudes from the support plate 14. A force sensor 2 is arranged between the two protruding cylindrical parts 51.

[0053] The upper cylindrical portion 61a of the upper sleeve-type component 61 is inserted into the upper connecting hole 53a from above, and the lower surface of the upper flange portion 61b abuts against the annular portion 53 around the upper connecting hole 53a.

[0054] The load-bearing part 3 overlaps on the force sensor 2, such that the first load hole 3a and the second load hole 3b are coaxial with the first through hole 14a and the second through hole 14b, respectively, that is, coaxial with the through holes of the two upper sleeve-shaped components 61. The upper shaft part 711b passes through the load-bearing part 3 in the first load hole 3a, and then inserts into the upper sleeve-shaped component 61 and is screwed into the upper nut 712. The upper head 711a abuts against the upper surface of the load-bearing part 3 around the first load hole 3a. Thus, the upper sleeve-shaped component 61 is fastened in the y-axis (vertical) direction by the upper fastening part 71, and the suspension member 5 is connected to the load-bearing part 3.

[0055] The second load hole 3b of the same load section 3 is also connected to a suspension member 5, and furthermore, another load section 3 and two suspension members 5 are connected on the opposite side in the x-axis direction. Thus, a metering container 4 is suspended from the two load sections 3 by four suspension members 5.

[0056] As described above, the suspension member 5 is configured such that axis A, i.e., the length direction, is parallel to the vertical (y-axis) direction. Therefore, during measurement, the load applied to the measuring container 4 mainly acts in the direction that stretches the suspension member 5 along its length. As a result, the measuring container 4 can be stably supported, and the suspension member 5 is less prone to deformation such as skewing. In particular, the upper connecting hole 53a and the lower sleeve-type member 62 are arranged along axis A, thereby aligning the point of force of the cylindrical part 51 on the load-bearing part 3 and the point of force from the plate part 52 toward the cylindrical part 51 in the vertical direction, thus enabling stable support of the measuring container 4.

[0057] It should be noted that, for ease of explanation, the above description begins with the lower connection part, but the assembly order is not limited to this.

[0058] The following is for reference Figure 7 and Figure 8 The metering container 4 and the suspension component 5 are held together by the upper sleeve-type component 61 and the lower sleeve-type component 62. Figure 8 Through Figure 7 A cross-sectional view of the upper sleeve-type component 61 being compressed by fastening the upper fastening part 71. However, in Figure 8 For ease of explanation, a front view rather than a cross-section is shown for the upper sleeve-type component 61.

[0059] exist Figure 7 Although the upper shaft portion 711b is engaged with the upper nut 712, the upper cylindrical portion 61a of the upper sleeve-shaped component 61 is not compressed due to the small screw-in amount, and remains in its natural state. When the screw-in amount of the upper shaft portion 711b into the upper nut 712 increases, the distance between the upper head 711a and the upper nut 712 shortens. Consequently, the distance between the upper nut 712 and the upper flange portion 61b shortens, such as... Figure 8 As shown, the upper cylindrical portion 61a is compressed in its height direction, i.e., the y-axis direction. As a result, the upper cylindrical portion 61a bulges radially. Furthermore, the upper flange portion 61b is sandwiched between the load-bearing portion 3 and the cylindrical portion 51, thereby fixing its position and compressing it in the y-axis direction. Thus, the annular portion 53 is held in the y-axis direction around the upper connecting hole 53a by the bulging portion of the upper cylindrical portion 61a and the upper flange portion 61b.

[0060] Although the illustration is omitted, at the connection point of the lower fastening part 72, the lower sleeve-shaped component 62 is compressed in the height direction, i.e., the x-axis direction, of its lower cylindrical portion 62a. Specifically, as the screwing amount of the lower shaft portion 721b into the lower nut 722 increases, the distance between the lower head 721a and the lower nut 722 shortens. Consequently, the distance between the lower nut 722 and the lower flange portion 62b shortens, and the lower cylindrical portion 62a is compressed in its height direction, i.e., the x-axis direction. As a result, the lower cylindrical portion 62a bulges radially. Furthermore, the lower flange portion 62b is clamped between the plate portion 52 and the handle 43, thereby fixing its position and compressing it in the x-axis direction. Thus, the handle 43 of the measuring container 4 is held in the x-axis direction around the first container hole 43a by the lower cylindrical portion 62a and the lower flange portion 62b. The same applies to the second container hole 43b.

[0061] The buffering effect of the upper sleeve-type component 61 and the lower sleeve-type component 62 is explained.

[0062] When the object to be measured is placed into the measuring container 4, an impact load is applied to the measuring container 4. At this time, the measuring container 4 can displace relative to the suspension member 5 within the elastic range of the lower sleeve-shaped member 62. In particular, the lower sleeve-shaped member 62 can displace in the shear direction, compression direction, and suspension direction between the measuring container 4 and the suspension member 5, that is, it can perform three-dimensional displacement. As a result, the impact load is mitigated. In addition, the lower sleeve-shaped member 62 absorbs the impact between the measuring container 4 and the suspension member 5, thereby causing the vibration of the measuring container 4 to decay rapidly in all directions. Furthermore, due to the lower sleeve-shaped member 62, the vibration transmitted from the measuring container 4 to the suspension member 5 is less than the vibration generated in the measuring container 4.

[0063] Furthermore, the suspension member 5 can displace relative to the load-bearing part 3 within the elastic range of the upper sleeve-shaped member 61. In particular, the upper sleeve-shaped member 61 can displace in the shear direction, compression direction, and suspension direction between the suspension member 5 and the load-bearing part 3, i.e., it can perform three-dimensional displacement. As a result, the impact load is further mitigated. In addition, the upper sleeve-shaped member 61 absorbs the impact between the suspension member 5 and the load-bearing part 3, thereby rapidly attenuating the vibration of the suspension member 5 in all directions. Furthermore, due to the presence of the upper sleeve-shaped member 61, the vibration transmitted from the suspension member 5 to the load-bearing part 3 is further reduced to less than the vibration transmitted from the metering container 4 to the suspension member 5.

[0064] As described above, the displacement between the metering container 4 and the suspension member 5, and the displacement between the suspension member 5 and the load-bearing part 3, can be achieved through the elasticity of the upper sleeve-type member 61 and the lower sleeve-type member 62. As a result, since the impact load acting on the suspension member 5, the load-bearing part 3, and the force sensor 2 is reduced, it is possible to suppress the occurrence of malfunctions such as skewing or damage to these components.

[0065] Meanwhile, the range of these displacements is limited to the elastic range of the upper sleeve-type component 61 and the lower sleeve-type component 62, and the vibration decays rapidly. Therefore, the time from the input of the measuring object to the calculation of the measuring result based on the output of the force sensor 2 is shorter than that of the prior art, and high measuring accuracy can be obtained.

[0066] In addition, the vibration ultimately transmitted to the force sensor 2 is significantly less than the vibration of the measuring container 4, which also helps to balance measurement accuracy and shorten the measurement time.

[0067] It should be noted that both the upper sleeve-type component 61 and the lower sleeve-type component 62 individually possess a buffering effect that reduces impact loads and attenuates vibrations in the shear, compression, and suspension directions, i.e., in three dimensions. In this embodiment, the orientation of the upper sleeve-type component 61 (first direction: y-axis direction) and the orientation of the lower sleeve-type component 62 (second direction: x-axis direction) intersect but are not parallel, further intersecting in the same plane, and further perpendicular, thereby achieving a higher buffering effect in all directions. Furthermore, preferably, either the first direction or the second direction is a vertical direction (i.e., the other direction is a horizontal direction). Since the first direction is a vertical direction, this condition is also satisfied in this embodiment.

[0068] Furthermore, the upper sleeve-type component 61 and the lower sleeve-type component 62 also have the effect of improving the uniformity of the load applied from the measuring container 4 to the force sensor 2. As shown in this embodiment, when the load is applied to the force sensor 2 via multiple suspension members 5, and when multiple force sensors 2 are provided, it is best to apply the load within and between the force sensors 2 in a nearly uniform balance. If the position of the measuring container 4 relative to the load-bearing part 3 is completely fixed, and the measuring container 4 cannot be displaced relative to the load-bearing part 3, then in order to achieve the above balance, it is necessary to adjust the size and position of each component extremely precisely. Alternatively, it is also possible to consider making the suspension member 5 have a structure that can change its length, so that the load deviation caused by dimensional error can be corrected by changing its length during assembly. However, since high precision is required during assembly, and the number of components increases when changing the length, the structure is complex. In contrast, as shown in this embodiment, by arranging the upper sleeve-type component 61 and the lower sleeve-type component 62 between the suspension component 5 and the load-bearing part 3 and between the suspension component 5 and the metering container 4, it is possible to absorb dimensional errors caused by machining tolerances and achieve near-equal load balance without length adjustment.

[0069] It should be noted that the composition, physical properties, shape, and size of the upper sleeve-type component 61 and the lower sleeve-type component 62 can be appropriately changed as long as the above-mentioned buffering effect is achieved. In addition, the upper sleeve-type component 61 and the lower sleeve-type component 62 are selected according to the natural vibration frequency of each component in the metering device and the performance required by the metering device, so as to obtain an optimal vibration attenuation rate (vibration frequency ratio).

[0070] For example, the upper sleeve-type component 61 and the lower sleeve-type component 62 can be made of known elastomers such as rubber, and preferably well-known anti-vibration rubber.

[0071] In the above embodiment, the number of support points of the metering container 4, that is, the number of suspension members 5 set for a metering container, is four, but it can also be three or less, or more than five.

[0072] 2. Control of Metering Device 1

[0073] Further reference Figure 9 The measurement of measuring device 1 is explained. Figure 9 This is a block diagram showing the general structure of the measuring device 1.

[0074] In addition to the above-described structure, the metering device 1 also includes: a supply drive unit 91 for opening and closing the supply gate 8, a discharge drive unit 92 for opening and closing the discharge gate, an output unit 93 for displaying the metering results, and a control device 94 that controls the operation of each unit and is connected to the force sensor 2. The control device 94 includes a supply control unit 941, a discharge control unit 942, a weight calculation unit 943, and an output control unit 944. The control device 94 is composed of an arithmetic unit such as a CPU, a memory, a timer, etc.

[0075] The supply control unit 941 controls the operation of the supply drive unit 91 to open the supply gate 8 and close it after a certain time or when the measured object reaches a predetermined weight (input time T1), thereby inputting the measured object from the storage tank into the measuring container 4. After the supply gate 8 closes, indicating that input is complete, and until vibration convergence occurs (waiting time T2), the weight calculation unit 943 reads the output value from the force sensor 2 and calculates the weight of the measured object based on this output value. The discharge control unit 942 opens the discharge gate after the supply gate 8 has opened, i.e., after the input time and waiting time (T1+T2) have elapsed from the start of input, discharging the measured object from the measuring container 4. By repeating the above actions, the measuring device 1 can intermittently measure the measured object.

[0076] The calculation result of the weight calculation unit 943, i.e. the measurement result, is stored in a memory (not shown). The output control unit 944 reads the measurement result and prompts the user via the output unit 93.

[0077] Time T2 is the time required for the vibration to converge to a level that allows the target measurement accuracy to be achieved. As described above, in the measuring device 1, the upper sleeve-type member 61 and the lower sleeve-type member 62, which are elastic bodies, absorb vibration and impact, thus enabling the measurement accuracy to be shortened while achieving the same measurement accuracy, or the measurement accuracy to be improved while maintaining the time T2.

[0078] It should be noted that calibration and other techniques used in existing metrology devices are also preferably applicable to this invention.

[0079] 3. Other implementation methods, etc.

[0080] As described above, the embodiments have been illustrated as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to this and can be applied to embodiments with appropriate changes, substitutions, additions, omissions, etc. Furthermore, the constituent elements described in the above embodiments can be combined to form new embodiments. In addition, the constituent elements described in the drawings and the summary of the invention may include, besides those necessary to solve the technical problem, elements that are used to illustrate the technology but are not necessary to solve the technical problem. Therefore, the presence of these non-essential constituent elements in the drawings or the summary of the invention should not be construed as their necessity.

[0081] For example, the following technologies are also disclosed in this application.

[0082] (1) The present invention can be applied to a measuring container having a force sensor, a load-bearing part that transmits the load to the force sensor, a measuring container that can contain the measuring object, and a suspension member that suspends the measuring container on the load-bearing part.

[0083] (2) The metering container may include a first upper buffer portion, a second upper buffer portion, and an upper fastening portion. The first upper buffer portion is an elastic body mounted on at least one of the load-bearing portion and the suspension member. The second upper buffer portion is an elastic body configured to be aligned with the first upper buffer portion in a predetermined direction. The upper fastening portion fastens the first and second upper buffer portions in the predetermined direction. One of the load-bearing portion and the suspension member is connected to the other by being clamped by the first and second upper buffer portions.

[0084] (3) The metering container may also include an upper sleeve-type component, which has: an upper cylindrical portion including a second upper buffer portion; and an upper flange portion extending radially outward from one end of the upper cylindrical portion as a first upper buffer portion. The upper sleeve-type component is configured such that the height direction of the upper cylindrical portion is parallel to the direction specified in (2) above. Figure 5 The illustrated upper sleeve-type component 61 is an elastic body having an upper cylindrical portion 61a and an upper flange portion 61b extending radially outward from one end of the upper cylindrical portion 61a. The upper cylindrical portion 61a includes a second upper buffer portion, and the upper flange portion 61b corresponds to a first upper buffer portion. The upper sleeve-type component 61 is configured such that the height direction of the upper cylindrical portion 61a (i.e., the direction of the through hole of the upper sleeve-type component 61) is parallel to the direction specified in (2) above.

[0085] (4) Figure 5As illustrated, the upper fastening part may have a bolt-nut structure. The illustrated upper fastening part 71 has an upper bolt 711 and an upper nut 712. The upper bolt 711 is inserted into the upper cylindrical part 61a, and the upper nut 712 is engaged with the upper bolt 711. By screwing the upper bolt 711 into the upper nut 712, the upper fastening part fastens the upper cylindrical part 61a and the upper flange part 61b in the direction specified in (2) above.

[0086] In this embodiment, the upper cylindrical portion 61a bulges outward in a radial direction, that is, in a direction perpendicular to the predetermined direction, by fastening the upper fastening portion 71. The suspension member 5 is connected to the load-bearing portion 3 by being clamped by the bulging portion (second upper buffer portion) of the upper cylindrical portion 61a and the upper flange portion 61b.

[0087] (5) However, as Figure 5 As shown in the embodiments illustrated, the first upper buffer portion and the second upper buffer portion can be independent components and are not included in a sleeve-type component.

[0088] (6) Regarding (2) above, "one of the load-bearing part or suspension part is connected to the other by being clamped by the first upper buffer part and the second upper buffer part," Figure 5 In the embodiments shown, the suspension member 5 is exemplified as the component held between the first upper buffer and the second upper buffer. However, the component held between the two upper buffers can also be the load-bearing member 3. In other words, the load-bearing member, the first upper buffer, the suspension member, and the second upper buffer can be arranged in a predetermined direction in the order of the first upper buffer, the load-bearing member, the second upper buffer, and the suspension member.

[0089] (7) The upper fastening part is not limited to a bolt-nut structure. It can also be a clamp or other parts, as long as the load-bearing part and the suspension part can be connected by fastening the first and second upper buffer parts.

[0090] (8) In (2) above, the first upper buffer part is "installed on at least one of the load-bearing part and the suspension part" and is not limited to installation by a bolt-nut structure such as the upper fastener 71. The first upper buffer part can also be clamped between the load-bearing part and the suspension part by other means such as a clip, or it can also be fixed to at least one of these parts by adhesive or the like.

[0091] (9) In Figure 5 In the configuration shown, the upper nut 712 is embedded in the upper cylindrical portion 61a of the upper sleeve-type component 61, but it is not limited to this and can also be provided as an independent component separate from the first and second upper buffer portions.

[0092] (10) As the “prescribed direction” of (2) above, Figure 5 The vertical direction is illustrated in the examples, but the invention is not limited thereto; it can also be a horizontal direction or other directions.

[0093] (11) In order to connect the load-bearing part and the suspension part, a load hole and an upper connecting hole in the specified direction may be formed on the load-bearing part and the suspension part, respectively. In addition, when the specified direction is vertical, the suspension part may also have a horizontal part extending horizontally below these load-bearing parts and a vertical part extending vertically from the horizontal part, and an upper connecting hole in the vertical direction may be formed in the horizontal part.

[0094] exist Figure 5 In this configuration, the specified direction is vertical. The load-bearing part 3 has a first load hole 3a and a second load hole 3b, which have vertical shafts. The suspension member 5 has an annular part 53 as a horizontal part and a cylindrical part 51 and a plate part 52 as vertical parts. The annular part 53 has an upper connecting hole 53a. With this shape, the suspension member 5 is not easily deformed even when subjected to loads from the measuring container 4 and the measuring object, and can maintain measuring accuracy even when measuring repeatedly. However, the horizontal and vertical parts are not limited to this shape. For example, the horizontal and vertical parts can also be flat plates, which can be combined to form an L-shape.

[0095] (12) Additionally, the upper sleeve-type component can be configured such that the upper cylindrical portion penetrates the horizontal portion through the upper connecting hole described in (10). In this case, the diameter of the upper connecting hole is preferably larger than the diameter of the load hole. Furthermore, the upper flange portion is disposed between the load-bearing portion and the horizontal portion.

[0096] Additionally, the upper bolt may have: an upper shaft portion that passes through a load hole and inserts into the upper sleeve-type component; and an upper head with a diameter larger than the load hole of the load-bearing portion, positioned above the load-bearing portion. The upper fastening portion can be screwed into the upper nut via the upper shaft portion to secure the upper cylindrical portion and the upper flange portion in the vertical direction. In this configuration, the horizontal portion is sandwiched between the bulge of the upper cylindrical portion and the upper flange portion around the upper connecting hole, thereby allowing the suspension member to be displaceably connected to the load-bearing portion. Figure 7 and Figure 8 The upper bolt 711 shown is an example of such an upper bolt.

[0097] (13) The metering container may include a first lower buffer portion, a second lower buffer portion, and a lower fastening portion. The first lower buffer portion is an elastic body mounted on at least one of the metering container and the suspension member. The second lower buffer portion is an elastic body configured to be aligned with the first lower buffer portion in a predetermined direction. The lower fastening portion fastens the first lower buffer portion and the second lower buffer portion in the predetermined direction. One of the metering container or the suspension member is connected to the other by being clamped by the first lower buffer portion and the second lower buffer portion.

[0098] (14) In Figure 5 Examples of combinations of (2) and (13) are shown, but a measuring container may also have the structure of (2) alone or the structure of (13) alone. The “prescribed direction” of (2) is sometimes referred to as the “first direction” and the “prescribed direction” of (13) is sometimes referred to as the “second direction”.

[0099] (15) The first and second lower buffer portions can be configured as sleeve-type components, similar to the first and second upper buffer portions. In other words, the metering container may include a lower sleeve-type component having: a lower cylindrical portion including a second lower buffer portion, and a lower flange portion extending radially outward from one end of the lower cylindrical portion as a first lower buffer portion. The lower sleeve-type component is configured such that the height direction of the lower cylindrical portion is parallel to the direction specified in (13) above.

[0100] Figure 5 The lower sleeve-type component 62 illustrated above is an elastic body having a lower cylindrical portion 62a and a lower flange portion 62b extending radially outward from one end of the lower cylindrical portion 62a. The lower cylindrical portion 62a includes a second lower buffer portion, and the lower flange portion 62b corresponds to the first lower buffer portion. The lower sleeve-type component 62 is configured such that the height direction of the lower cylindrical portion 62a (i.e., the direction of the through hole of the lower sleeve-type component 62) is parallel to the direction specified in (13) above.

[0101] (16) such as Figure 5 As illustrated, the lower fastening part may have a bolt-nut structure. The illustrated lower fastening part 72 has a lower bolt 721 and a lower nut 722. The lower bolt 721 is inserted into the lower cylindrical part 62a, and the lower nut 722 is engaged with the lower bolt 721. By screwing the lower bolt 721 into the lower nut 722, the lower fastening part 72 fastens the lower cylindrical part 62a and the lower flange part 62b in the direction specified in (13) above.

[0102] In this embodiment, the lower cylindrical portion 62a bulges outward radially outward, i.e., in a direction perpendicular to the predetermined direction, by fastening the lower fastening portion 72. The measuring container 4 (especially the handle 43) is connected to the suspension member 5 by being clamped by the bulging portion (second lower buffer portion) of the lower cylindrical portion 62a and the lower flange portion 62b.

[0103] (17) However, the first lower buffer and the second lower buffer can be independent components and not included in, for example Figure 5 In a sleeve-type component shown in the embodiment illustrated.

[0104] (18) Regarding the above (13) "one of the metering container or suspension component is connected to the other by being clamped by the first lower buffer and the second lower buffer," in Figure 5 In the embodiments shown, the measuring container 4 (particularly the handle 43) is exemplified as the component held by the first lower buffer and the second lower buffer. However, the component held by the handle can also be the suspension member 5. In other words, the components can be arranged in a predetermined direction in the order of the suspension member, the first lower buffer, the measuring container, and the second lower buffer, or they can be arranged in a predetermined direction in the order of the second lower buffer, the suspension member, the first lower buffer, and the measuring container.

[0105] (19) The lower fastening part is not limited to a bolt-nut structure. It can also be a clamp or other parts, as long as the metering container and the suspension can be connected by fastening the first and second lower buffer parts.

[0106] (20) In (13) above, the first lower buffer part is “installed on at least one of the metering container and the suspension part” and is not limited to being installed by a bolt-nut structure such as the lower fastener 72. The first lower buffer part can also be clamped between the metering container and the suspension part by other means such as a clamp, or it can also be fixed to at least one of these parts by adhesive or the like.

[0107] (21) In Figure 5 In the configuration shown, the lower nut 722 is embedded in the lower cylindrical portion 62a of the lower sleeve-type component 62, but it is not limited to this and can also be provided as an independent component separate from the first and second lower buffer portions.

[0108] (22) As specified in (13) above, in Figure 5 The forms shown illustrate a horizontal direction, but the invention is not limited thereto; it may also be a vertical direction or other directions.

[0109] (23) In order to connect the measuring container to the suspension member, a container hole and a lower connecting hole in the specified direction as described in (13) may be formed on the measuring container and the suspension member, respectively. In addition, preferably, the suspension member has a vertical portion extending in the vertical direction, and the lower connecting hole is formed on the vertical portion.

[0110] exist Figure 5 In the above, the specified direction is horizontal. The measuring container 4 has container holes 43a and 43b, which have horizontal axes. The plate portion 52, which is part of the vertical portion of the suspension member 5, has a lower connecting hole, which has a horizontal axis in the plate portion 52.

[0111] (24) The lower sleeve-type component can be configured such that the lower cylindrical portion penetrates the metering container through the container hole described in (23). In this case, the diameter of the container hole is preferably larger than the diameter of the lower connecting hole. In addition, the lower flange portion is disposed between the suspension member and the metering container.

[0112] Additionally, the lower bolt may have: a lower shaft portion that passes through the lower connecting hole and inserts into the lower sleeve-type component; and a lower head portion with a larger diameter than the lower connecting hole, clamping the suspension member and positioned on the opposite side of the lower flange portion. The lower fastening portion can be screwed into the lower nut via the lower shaft portion to horizontally fasten the lower cylindrical portion and the lower flange portion. The measuring container is clamped around the container hole between the bulge portion of the lower cylindrical portion and the lower flange portion, thereby allowing the measuring container to be displaceably connected to the suspension member. Figure 7 and Figure 8 The lower bolt 721 shown is an example of such a lower bolt.

[0113] (25) In Figure 5 In the configuration shown, the measuring container 4 includes a container body 41 and a handle 43, with the handle 43 and the suspension member 5 connected by a lower fastening part 72. However, this is only one example of the connection configuration between the measuring container and the suspension member, and the handle 43 is not an essential structure for fixing the measuring container 4. For example, a container hole, serving as a through hole for connection, can be provided on the side wall of the container body 41 at a location where the object being measured is unlikely to leak out, and the measuring container 4 can be fixed through this container hole.

[0114] (26) In the combination of (2) and (13) above, preferably, the first direction, which is the direction specified in (2) above, is different from the second direction, which is the direction specified in (13) above. Furthermore, the second direction is perpendicular to the first direction, thereby achieving a more uniform buffering effect in all directions. It should be noted that when the first and second directions are "perpendicular," these directions preferably lie in the same plane, but they can also be in a torsional (opposite-plane perpendicular) relationship. Additionally, preferably, one of the first or second directions is a vertical direction, and the other is a horizontal direction. Figure 5 In the form shown, as an example of such a structure, the first direction is the vertical direction and the second direction is the horizontal direction.

[0115] (27) When the first direction is vertical and the second direction is horizontal, the suspension member may include a horizontal portion provided in the horizontal direction and a vertical portion extending downward from the horizontal portion in the vertical direction. An upper connecting hole (with a shaft) in the vertical direction is formed in the horizontal portion, and a lower connecting hole (with a shaft) in the horizontal direction is formed in the vertical portion, thereby connecting the horizontal portion of the suspension member to the load-bearing part and the vertical portion to the metering container. Figure 5 The suspension member 5 shown is an example of such a suspension member. However, as mentioned above, the suspension member is not limited to this shape.

[0116] (28) Any combination of the forms described above is also included in the disclosure of this application.
