Abstract

[PROBLEMS] A particulate supply device capable of supplying a trace amount of particulates and a particulate measuring device. [MEANS OF SOLVING PROBLEMS] A plurality of particulate passing holes (14B) are formed through the bottom wall (14) attached to the small-diameter tube unit (12) of a particulate drum (10) provided to a particulate supply device (100). Since, only when particulates are set at rest in the small-diameter tube unit (12), particulates stick together to form a particulate arch that blocks the particulate passing holes (14B) allowing no particulate to flow out through the holes (14B). When a bottom turning member (26) is turned above the bottom wall (14), the particulate arch crumbles to allow particulates to fall through the holes (14B). When the bottom turning member (26) is stopped turning, a new particulate arch is formed immediately to block the holes (14B). Since only a trace amount of particulates falls when a particulate arch crumbles, a trace amount of particulates can be supplied and measured by controlling the rotation of the bottom turning member (26).

 [Invention of claim 6]

 According to the invention of claim 6, since the granular material passage hole is formed so that the opening area gradually increases toward the lower end portion, the granular material arch is formed on the lower end side of the granular material passage hole. This is a relatively strong adhesion and prevents the powder from flowing smoothly through the particle passage hole.

 [0036] [Invention of claim 7]

 According to the seventh aspect of the invention, since the bottom turning member has an angle of attack, the powder is pressed against the bottom wall side by turning the bottom turning member. Thereby, an external force can be efficiently applied to the granular material arch formed on the bottom wall, and the granular material can be forcibly dropped below the bottom wall from the granular material passage hole.

[0037] [Invention of claim 8] According to the invention of claim 8, the bottom surface rotating member having the adjacent lower end surface that is adjacent in parallel with the bottom wall upper surface rotates above the bottom wall.

 [0041] [Invention of Claim 12]

 According to the twelfth aspect of the present invention, the clogging of the powder particles inside the conical portion can be prevented by rotating the flow assisting rotating blade inside the conical portion.

[0042] [Invention of Claim 13]

 According to the invention of claim 13, the clogging of the granular material inside the granular material replenishing tube can be prevented by rotating the flow assisting rotating plate inside the granular material replenishing tube.

[0043] [Invention of Claim 14]

According to the granular material supply device of the invention of claim 14, when the bottom turning member is rotated at a relatively low speed, the first arch crushing leg portion having a relatively small distance between the lower end portion and the bottom wall is , While applying an external force to the granule arch and breaking it, the distance between the lower end and the bottom wall is relatively large. The second arch crushing leg only passes through the upper part of the granular arch, and does not give an external force to break the granular arch. Therefore, only when the first arch crushing leg passes above the granular material passage hole, the granular arch collapses and falls below the bottom wall.

 [0044] On the other hand, when the bottom turning member is rotated at a relatively high speed, not only the first arch crushing leg but also the second arch crushing leg gives an external force to the granular arch. . Specifically, when the lower end of the second arch crushing leg passes over the granular arch, the powder that flows downward, that is, toward the bottom wall, is guided by the second arch crushing leg. The granule arch is broken by the granule. Therefore, when the first and second arch crushing legs pass above the granular material passage hole, the granular arch collapses and falls below the bottom wall. That is, according to the present invention, when the rotational speed of the bottom turning member is changed from low speed to high speed, the discharge amount of the granular material can be increased rapidly.

 [0045] [Invention of Claim 15]

 According to the invention of claim 2, the external force is applied to the granular arch by causing the granular material to flow obliquely downward, that is, toward the upper surface of the bottom wall by the guide of the first or second arch crushing leg. be able to.

 [0046] [Invention of claim 16]

 According to the invention of claim 16, since the second arch crushing leg can disintegrate the granular arch in a wider range than the first arch crushing leg, the rotational speed of the bottom turning member is reduced. When the speed is changed from high to low, the amount of discharged particulate matter can be increased more rapidly.

 [0047] [Invention of claim 17]

 According to the invention of claim 17, when the rotational speed of the bottom turning member is relatively low, the granular material slips between the plurality of first arch crushing legs provided side by side with a space therebetween. Therefore, only the part of the granular material where the lower end of the first arch crushing leg has passed is broken. On the other hand, when the rotational speed is relatively high, it is difficult for the granular material to pass between the plurality of first arch crushing legs, and the lower end of the first arch crushing leg passes. And the granule arch in the vicinity thereof can be broken.

[0048] [Invention of Claim 18] According to the invention of claim 18, since the transverse distance force S when the arch crushing leg crosses the upper part of the slit is longer than that when the slit is extended in the turning radius direction of the bottom turning member, a wider range of powder particles The body arch can be broken.

 [0049] It should be noted that the slits as the plurality of granular material passage holes may extend linearly or may be curved in an arc shape. When the slit is arcuate, the arc may be curved around the center of rotation of the arch crushing leg, or it may be curved from one end to the other end while turning to the center of rotation of the arch crushing leg. You may make it the circular arc shape which approaches.

 [0050] [Invention of Claim 19]

 According to the invention of claim 19, the powder adhered to the inner surface of the powder container due to static electricity or the like can be scraped off by the adhered powder removal leg as the bottom turning member rotates.

[0051] [Invention of claim 20]

 According to the invention of claim 20, in the powder container, the granular material is an annular shape between the inner disc disposed at the center of the lower end of the large-diameter cylindrical portion and the side wall of the large-diameter cylindrical portion. Powder that flows downward from the space and accumulates on the upper surface of the horizontal stepped wall that joins the large-diameter cylindrical part and the small-diameter cylindrical part, and has an angle of repose between the inner circular plate and the horizontal stepped wall. Form body mountain. Since the gap between the inner circular plate and the horizontal step wall is closed by the granular material pile, the granular material does not fall into the small-diameter cylindrical portion when the intermediate turning member is stopped.

 [0052] When the intermediate turning member is turned, the intermediate turning member guides the powder particles to the inside of the small-diameter cylindrical portion while breaking the powder particles. In addition, as soon as the powder pile is broken, the powder is supplied from the annular space and a new powder pile is formed. It can be guided to the inside of the department.

 [Invention of Claims 21 and 22]

Because the fluidity of the granular material is low !, the intermediate rotating member may not be able to smoothly guide the granular material into the small-diameter cylindrical portion. On the other hand, according to the invention of claim 21, when the intermediate swirling member rotates on the upper surface of the horizontal step wall and passes the swirl guide, the intermediate swirling member and the swirl guide cooperate with each other in the form of particles. Since the body is moved to the center side, even the low fluidity and granular material can be smoothly guided to the small diameter cylindrical portion. Here, one spiral guide Only one or a plurality of them may be provided. Further, as in the invention of claim 22, it is more effective if the spiral guide has a shape extending along any one of the import curve, the logarithmic spiral curve, and the Archimedes spiral curve.

 [0054] [Invention of Claim 23]

 According to the invention of claim 23, it is possible to control the supply motor by the motor drive control unit and rotate it at an arbitrary and constant speed, thereby supplying a desired constant and minute amount of powder particles S.

 [0055] [Invention of Claim 24]

 According to the granular material measuring device of claim 24, if the weight of the desired granular material is set, the total weight of the granular material supplied minutely from the granular material supply device reaches the set weight. When this happens, the rotation of the supply motor stops. As a result, it is possible to weigh out the amount of powder that matches the set weight and the range of minute errors.

 BEST MODE FOR CARRYING OUT THE INVENTION

 [0056] [First embodiment]

 Hereinafter, a first embodiment according to the present invention will be described with reference to FIGS. The granular material supply apparatus 100 shown in FIG. 1 supplies the granular material from the hopper 30 to the granular material drum 10 (corresponding to “the granular material container” of the present invention), and the lower surface of the granular material drum 10. It is configured to supply granular material to the lower receiving tray 1 04!

 As shown in FIG. 1, the hopper 30 includes an inverted conical container 31 (corresponding to the “conical portion” of the present invention) and a cylindrical chute 32 (“powder of the present invention”) extending from the lower end thereof. The top opening of the container 31 is closed by a lid 33. A motor 35 is provided on the upper part of the lid 33, and the flow assisting rotating member 36 that stirs the powder particles inside the hopper 30 is rotated!

[0058] The flow assisting rotation member 36 rotates inside the hopper 30 to prevent the powder particles in the hopper 30 from adhering to be hardened or clogged (so-called bridge). As shown in FIGS. 2 (A) and 2 (B), the flow assisting rotating member 36 is formed in accordance with the shape of the hopper 30 and has an inverted triangular flow assist wing 36A (the `` flow The flow-down auxiliary plate 36B (corresponding to the “flow-down auxiliary rotation plate” of the present invention) is suspended from the lower end of It has a structure. The descending auxiliary blade 36A has a side stirring piece 36D made of a rectangular plate on each hypotenuse of the inverted triangle. Each side stirring piece 36D extends in a plate shape in the generatrix direction of the inverted conical portion of the hopper 30 and rotates in a state adjacent to the inner tapered surface of the container 31 so that the granular material is formed on the inner tapered surface. Prevents adhesion.

 [0059] As shown in FIGS. 2 (A) and 2 (B), the flow assisting plate 36B is formed by cutting a flat plate into a crank shape, and is rotated by the motor 35 in the chute 32. The granular material in the chute 32 is stirred and allowed to flow downward.

 [0060] As shown in FIG. 1, the powder drum 10 includes a large-diameter cylindrical portion 11, a small-diameter cylindrical portion 12, and a granular material discharge portion 13 in order from the top. It has a structure. A disc-shaped bottom wall 14 is detachably mounted on the horizontal step surface between the small diameter cylindrical portion 12 and the granular material discharge portion 13. The upper end of the powder drum 10 is open, covered with a lid 16, and a supply motor 15 is provided at the center of the upper surface of the lid 16. A rotation shaft 15A (corresponding to a “rotation output shaft” of the present invention) of the supply motor 15 passes through the lid 16 and extends along the center shaft in the powder drum 10. Furthermore, an opening is formed in a part of the lid 16, and the lower end of the chute 32 of the hopper 30 is inserted into the opening!

 [0061] The lower end opening 32A of the chute 32 is abutted with a flat horizontal stepped wall 20 joining the large-diameter cylindrical portion 11 and the small-diameter cylindrical portion 12 of the granular drum 10 with a predetermined interval. ing . Then, the powder body force S from which the lower end opening 32A force of the chute 32 is also discharged is temporarily accumulated on the upper surface of the horizontal step wall 20 (hereinafter referred to as “horizontal step surface 21”), and the pile of the powder is supplied to the supply mode. It is broken by a scraper 22 attached to the rotary shaft 15A of the cylinder 15 and pulled into the small diameter cylindrical portion 12.

 [0062] As shown in FIG. 3, the scraper 22 extends the dust collection blades 23 and the dusting blades 24 laterally from a cylindrical shaft portion 25 attached to the rotation shaft 15A (see FIG. 1) of the supply motor 15. It has a different structure. The dust collection blade 23 has an arc shape that swells in the opposite direction to the rotation direction (the direction of the arrow in FIG. 3), while the dust wing 24 has an arc shape that swells in the rotation direction side. Further, as shown in FIG. 4, the dust collection blade 23 extends to a position where the tip thereof is adjacent to the inner side surface 11C of the large-diameter cylindrical portion 11, and the dust collection blade 24 is shorter than that.

In addition, the dust collection blade 23 and the dust collection blade 24 are adjacent to the horizontal step surface 21. And powder collection The wings 23 guide the particles on the horizontal stepped surface 21 toward the center and take them into the small-diameter cylindrical portion 12, and the dust wings 24 move the particles that have been taken in too much by the dust wings 24 to the outside. When the dust collection blades 23 pass next, the particulate pressure in the small diameter cylindrical portion 12 is easily stabilized. Further, the dust collection blade 23 and the dust collection blade 24 cooperate to agitate the powder and pulverize the lump of the powder. Furthermore, when the powder is a mixture of two or more powders, the degree of mixing of the two powders can be increased by repeating this accumulation and dispersion. The dust collection blade 23 corresponds to the “upper turning member” of the present invention.

[0064] The granular material supplied from the hopper 30 is supplied from the lower end opening 32A of the chute 32 to the horizontal stepped surface 21, and as shown in Fig. 5, the granular material is below the lower end opening 32A of the chute 32. The body piles up and closes the lower end opening 32A of the chute 32. The angle (repose angle) with respect to the horizontal surface of the slope of this sedimentary mountain is a constant angle depending on the type of powder. In the present embodiment, by utilizing this property, it is possible to prevent excessive discharge of powder particles from the chute 32 without providing an opening / closing means at the lower end opening 32A of the chute 32. In addition, since the powder particles of the chute 32 are temporarily received by the horizontal stepped surface 21, the powder pressure in the small-diameter cylindrical portion 12 is stabilized, and the powder particles from the particle passage hole 14B described later. Discharge can be stabilized.

 [0065] Now, the bottom wall 14 of the powder drum 10 is provided with a plurality of bottom wall upper surface protrusions 14A as shown in FIGS. 6 (A) and 6 (B). Each bottom wall upper surface protrusion 14A forms a triangular pyramid with one of its side surfaces standing upright, and is arranged along two concentric circles on the bottom wall 14. A granular material passage hole 14B is formed so as to penetrate from one side surface of the bottom wall upper surface protrusion 14A toward the back surface of the bottom wall 14. As shown in FIG. 7, the granular material passage hole 14B is formed by being bent halfway below the bottom wall upper surface protrusion 14A, and passes through the granular material on the upright side of the bottom wall upper surface protrusion 14A. The upper end opening of the hole 14B is arranged. Further, on the back surface of the bottom wall 14, a lower end opening of the granular material passage hole 14B is disposed directly below the bottom wall upper surface protrusion 14A, and is open vertically downward.

 [0066] The upper end opening 1 of the granular material passage hole 14B 1 faces the direction opposite to the turning direction of the bottom turning member 26 described later.

[0067] Here, as shown in FIG. 7, the granular material passage hole 14B has a granular material deposited on the bottom wall 14. At the same time, the granular material arch is formed by the granular material adhering to the upper end opening of the granular material passage hole 14B, and the granular material arch is sized so that the granular material can pass therethrough. ing. In other words, the granular material passage hole 14B has a size several to ten times larger than the particle size of the granular material. In addition, since the optimum size of the granular material passage hole 14B differs depending on the properties of the granular material, etc., there are multiple types of bottom walls 14 with different granular particle passage holes 14B. Before using the feeder 100, the bottom wall 14 suitable for the granular material can be selected and replaced.

 As shown in FIG. 1, the small-diameter cylindrical portion 12 is provided with a bottom surface turning member 26 that turns on the bottom wall 14. As shown in FIG. 8, the bottom swivel member 26 has two swivel plates 27, 27 extending in a radial direction opposite to each other from a shaft portion 29 connected to the rotation shaft 15 </ b> A of the supply motor 15. The swivel leg 28 is suspended from the lower end!

 [0069] As shown in FIG. 8, the swivel plate 27 is a horizontally long rectangular flat plate having an angle of attack that is inclined so that the front end edge side of the swivel plate 27 is above the rear end edge side with respect to the swivel direction. Yes. When the swivel plate 27 is swung on the bottom wall 14, it turns while pressing the powder in the small-diameter cylindrical portion 12 against the bottom (bottom wall 14 side). Apply external force to the body. Further, the lower end surface of the swivel leg portion 28 is opposed to the flat surface between the bottom wall upper surface protrusions 14A of the bottom wall 14 with a gap (see FIG. 10). When the turning plate 27 turns, the turning leg portion 28 moves between the bottom wall upper surface protrusions 14A and applies an external force to the granular arch.

[0070] This completes the description of the configuration of the present embodiment. Next, the function and effect of this embodiment will be described. As shown in FIG. 1, the supply motor 15 is driven in a state where powder particles are accommodated in the hopper 30. Then, it is drawn into the small-diameter cylindrical part 12 by the rotation of the granular material force S scraper 22 and accumulates on the bottom wall 14 (see FIG. 9). At this time, since the powder particles adhere to each other to form a powder particle arch that closes the powder particle passage hole 14B, the powder material does not pass through the powder particle passage hole 14B only by its own weight. Then, when the bottom turning member 26 turning in the small-diameter cylindrical portion 12 passes in the vicinity of the powder arch closing each of the powder passage holes 14B, these powder arches are subjected to external force. As a result, the granular material that formed the granular arch is discharged downward from the granular material passage hole 14B. Then, a new granule arch is immediately formed in the granule passage hole 14B and closed again. Once the granule arch Since the amount of powder flowing out of the granular material passage hole 14B is extremely small before it breaks down and is formed again, a small amount of granular material is supplied while the bottom swivel member 26 is swung. The power S to do.

 [0071] Further, as shown in FIG. 10, since the swivel plate 27 of the bottom swivel member 26 has an angle of attack, the bottom swivel member 26 swivels to push the granular material against the bottom wall 14 side. Be Thereby, an external force can be efficiently applied to the granular material arch formed on the bottom wall 14, and the granular material can be forcibly dropped from the granular material passage hole 14B below the bottom wall. In addition, the swivel legs 28 suspended from the swivel plate 27 stir the powder and prevent the powder from clumping while applying external force to the powder arch to pass the powder through the powder. It can be dropped below the bottom wall 14 from the hole 14B.

 [0072] Now, when a predetermined amount of powder, for example, lOmg powder, is measured, it may be performed as follows. That is, as shown in FIG. 1, the tray 104 is placed on the weighing instrument 102 and placed below the powder supply device 100, and the value of the weighing instrument 102 is not confirmed. However, the supply motor 15 is rotated to supply fine particles little by little. If the supply motor 15 stops rotating when the value of the measuring instrument 102 reaches 10 mg, the force S can be measured by measuring lOmg powder. Further, if the rotation speed is reduced before the value of the measuring instrument 102 reaches lOmg, the supplied granular material becomes even smaller, so that the force S can be measured more accurately. By reducing the number of swivel legs 28 that are suspended from the lower end of the swivel plate 27, the supplied granular material can be fed in a very small amount.

 [0073] As described above, according to the granular material supply apparatus 100 of the present embodiment, the force S for supplying a very small amount of granular material can be obtained. Therefore, as described above, a very small amount of granular material is weighed out. be able to.

 [0074] [Second Embodiment]

A second embodiment of the present invention is shown in FIG. 11 and relates to a powder particle measuring apparatus 101 according to the present invention. In this granular material measuring device 101, a measuring device 102 and a control device 103 (corresponding to the “motor drive control unit” of the present invention) are combined with the granular material supply device 100 of the first embodiment. Then, when the weight of the desired granular material is set in the control device 103 and a start switch (not shown) is turned on, the supply motor 15 is driven to allow the granular material to be received from the granular material supply device 100 by a small amount. To be supplied. In addition, the control device 103 is a measuring instrument 1 When the measured value of 02 is taken in and the measured value reaches the set weight, the supply motor 15 stops rotating. As a result, it is possible to weigh out the amount of powder that matches the set weight within a range of minute errors.

 [0075] [Third Embodiment]

 This embodiment is shown in FIGS. 12 to 15, and the shapes of the bottom wall and the bottom surface turning member are different from those of the first embodiment. That is, as shown in FIG. 12, the bottom wall 60 has a circular flat plate shape, and the upper and lower surfaces are flat. Then, the granular material passage hole 60B is formed through in the normal direction of the bottom wall 60, and the opening area gradually increases toward the lower end as shown in FIG. According to this configuration, it is possible to smoothly supply a granular material having a relatively strong adhesive force through the granular material passage hole 60B. In addition, since the opening area of the granular material passage hole 60B gradually expands downward, the granular material arch is prevented from being formed on the lower end side of the granular material passage hole, and the adhesion force is relatively low. Strong particles can be smoothly fed through the particle passage hole 60B.

 Further, as shown in FIG. 14 (A), the bottom turning member 43 of the present embodiment has a shape in which the turning legs 28 are excluded from the bottom turning member 26 of the first embodiment. The swivel plate 2 7 swivels with the lower end portion adjacent to the upper surface of the bottom wall 60.

 [0077] Even with such a configuration, an external force can be applied to the granular material arch formed in the granular material passage hole 60B to break it, and it can flow out of the granular material passage hole 60B. Here, the external force applied to the powder arch by the swivel plate 27 is larger than the external force applied by the bottom swivel member 26, so that it may be used for a powder with low fluidity, In order to increase the discharge amount of the granular material from the through holes 60B and 61B, the bottom surface turning member 43 may be used.

[0078] Note that the shape of the granular material passage hole 60B in the case of using the bottom wall 60 having no protrusion is not limited to a circular shape, and may be a polygonal shape. The same effect can be obtained even with the bottom wall 61 having the rectangular particle passage hole 61B as shown in FIGS. 15 (A) and 15 (B). Further, like the bottom turning member 46 shown in FIG. 14 (B), the turning plate 47 may be formed perpendicular to the turning direction. In this case, since the swivel plate 47 is not inclined, a strong external force like the bottom swivel member 46 cannot be applied to the granular arch, but the bottom swivel Since an external force stronger than that of the rotating member 26 can be applied, it may be appropriately selected depending on the type of the granular material. Note that the swivel plate lower surfaces 27B and 47B of the bottom swivel members 43 and 46 correspond to the “adjacent lower end surface” according to the present invention.

 [0079] [Fourth Embodiment]

 The fourth embodiment is shown in FIGS. 16 and 17, and the shape of the granular drum 70 is different from that of the first embodiment, and the conical cylinder part is interposed between the large diameter cylinder part 11 and the small diameter cylinder part 12. 71. Further, a stirring blade 18 (corresponding to the “conical cylinder part turning member” of the present invention) is attached to the rotating shaft 15A of the supply motor 15. As shown in FIG. 17, the stirring blade 18 has a pair of stirring plates 18A, 18A. These stirring plates 18A, 18A straddle the conical cylinder portion 71 and the small diameter cylindrical portion 12, and Extends in the direction of the bus. When the supply motor 15 rotates, the upper end side of the stirring plate 18A rotates adjacent to the inner tapered surface 71A of the conical cylinder part 71, and the lower end side of the stirring plate 18A stirs the inside of the small diameter cylindrical part 12. To do.

 As shown in FIG. 16, the lower end opening 32A of the chute 32 is arranged in the powder drum 70 so as to abut against the inner tapered surface 71A of the conical cylinder part 71 from above. The granular material discharged from the lower end opening 32A of the chute 32 flows down to the small diameter cylindrical portion 12 because the inner tapered surface 71A is inclined. When the inside of the small-diameter cylindrical portion 12 is filled with powder particles (state shown in FIG. 16), the granular material that cannot flow down into the small-diameter cylindrical portion 12 also accumulates in the conical cylindrical portion 71, and there is a pile of deposits below the lower end opening 32A. The lower end opening 32A is closed. As a result, in this embodiment as well, as in the first embodiment, excessive powder particles from the shout 32 to the conical cylinder portion 71 can be obtained without providing an opening / closing means at the lower end opening 32A of the chute 32. It can be prevented from being discharged.

 [0081] [Fifth Embodiment]

This fifth embodiment is shown in FIG. 18 and FIG. 19, and does not use the hopper 30, and inside the large-diameter cylindrical portion 11 in the powder drum 10, the powder control disk 38 and the powder particles. The difference from the first embodiment is that a rolling bar 39 is provided. As shown in FIGS. 18 and 19, the granular material control disk 38 is a flat disk having a diameter smaller than the diameter of the large-diameter cylindrical portion 11 and larger than the diameter of the small-diameter cylindrical portion 12, and the large-diameter cylindrical portion. It is mounted horizontally on the top of the scraper 22 that swivels at the bottom of the eleven. When the granular material control disk 38 is attached and the granular material is put into the large diameter cylindrical part 11, the granular material is placed between the edge of the granular material control disk 38 and the inner surface 11 C of the large diameter cylindrical part 11. Can ring It flows down from the space 94 onto the horizontal step surface 21.

 [0082] On the other hand, the powder body pouring bar 39 is a flat plate disposed adjacent to the upper part of the powder body control disk 38, and the powder body control disk 38 rotates to turn the powder body control disk 38. It is provided to sprinkle the upper granular material to the edge. By attaching the flat surface of the powder particle spreading bar 39 to the side surface of the rotating shaft 15A of the supply motor 15 in the tangential direction, it can be inclined with respect to the rotation direction, and the powder particle control disk 38 The powder is pushed out to the edge of the powder control disk 38. In addition, the granular material spreading rod 39 has a tip extending to a position adjacent to the inner surface 11C of the large-diameter cylindrical portion 11, and the extruded granular material is moved to the edge of the granular material control disk 38. From the annular space 94 between the inner surface 11C and the inner surface 11C. Furthermore, it is possible to agitate the granular material in the large-diameter cylindrical portion 11 with the granular material discharging rod 39 to prevent the granular material from solidifying or clogging. As a result, it is possible to stably flow down the granular material on the upper part of the granular material control disk 38 onto the horizontal step surface 21.

 [0083] The granular material flowing down to the horizontal step surface 21 forms a pile of powder fluid between the granular material control disk 38 and the horizontal step surface 21, as in the case of the hopper 30 in the first embodiment. To do. Again, the angle of repose of the piles of the formed granular material is constant depending on the granular material, so that excessive granular material should not be supplied from above the granular control disk 38 to the horizontal step surface 21. That power S. That is, the annular space 94 formed between the edge of the granular material control disk 38 and the inner surface 11C of the large diameter cylindrical portion 11 is blocked by the piles of granular particles so that the granular materials are not discharged. In addition, it is possible to force the powder control disk 38 and the horizontal stepped surface 21 of the large-diameter cylindrical portion 11 to approach each other so that no excessive powder is supplied.

 [0084] Further, since the granular material flowing down from the upper part of the granular material control disk 38 is once received by the horizontal stepped surface 21, the granular material pressure in the small diameter cylindrical portion 12 is stabilized. In this way, even if the hopper 30 is not used, the powder control disc 38 and the powder feed rod 39 are installed in the large-diameter cylindrical portion 11, so that the hopper 30 in the first embodiment can be Similar effects can be achieved.

 [0085] [Sixth Embodiment]

A sixth embodiment of the present invention is shown in FIG. 20 to FIG. 31, and relates to a granular material measuring apparatus 101 according to the present invention. In this granular material measuring device 101, a measuring device 102 and a control device 103 are combined with a granular material supply device 90. And the granular material of this embodiment The feeding device 90 is different from the fifth embodiment in that the shape of the bottom wall and the scraper and the bottom turning member are an integral part.

As shown in FIG. 20, the granular material measuring device 101 is provided with a granular material supply device 90 above a measuring instrument 102 (specifically, an electronic balance). The powder / particle supply device 90 is suspended in a windshield 105 installed so as to surround the side of the weighing pan 102A of the measuring instrument 102. Specifically, it is arranged at a position just above the weighing pan 102A by a bracket 107 locked to the upper edge of the windshield 105, and is placed on the weighing pan 102A from the powder drum 91 containing the powder. It is configured to discharge the powder particles toward the receiver 108 (weighing cup, vial, etc.).

 As shown in FIG. 21, the upper end of the powder drum 91 is open and is closed by the upper end cap 106! The upper end cap 106 is screwed onto the outer peripheral surface of the upper end of the powder drum 91, and the supply motor 15 is fixed to the center of the upper surface. An in-container rotation member 80 is attached to the lower end portion of the rotation shaft 15A of the supply motor 15.

 [0088] The in-container rotating member 80 rotates in the powder drum 91 and scrapes off the powder particles piled up along the side wall 11A of the large diameter cylindrical portion 11 in the horizontal stepped surface 21 to reduce the small diameter cylindrical portion. Send to 12. As shown in FIG. 25, the in-container rotating member 80 includes a cantilever-shaped powder collecting blade 82 and a dusting blade 83 extending laterally from an axial center plate 84 fixed to the rotating shaft 15A. Yes. These dust collection blades 82 and dust distribution blades 83 are arranged in a gap between the granular material control disk 38 (corresponding to the “inside-container disk” of the present invention) and the horizontal step wall 20, and Rotates in a horizontal plane while sliding.

 [0089] As shown in FIG. 26, the powder collection blade 82 has a bent structure in which a plurality of flat plates are connected so as to swell in the opposite direction to the rotation direction of the in-container rotating member 80 (the direction of the solid line arrow in FIG. 26). On the other hand, the dust wings 83 extend straight toward the side wall 11A of the large-diameter cylindrical portion 11 in a state where the dust wings 83 are inclined with respect to the rotation direction of the in-container rotating member 80. In addition, the dust collection blade 82 extends outward from the granular material control disk 38, and its tip reaches a position adjacent to the side wall 11A of the large-diameter cylindrical portion 11 (see FIG. 23 and FIG. 24). 83 is getting shorter. The dust collection blade 82 corresponds to the “intermediate turning member” of the present invention.

[0090] As shown in FIG. 25, the shaft center plate 84 is disposed at the root of the dust collection blade 82 of the shaft plate 84. An auxiliary guide wall 81 that is cut and raised obliquely from the seat 84 is formed. The auxiliary guide wall 81 is inclined so as to gradually descend in the direction in which the granular material is guided by the powder collection blades 82 (in the direction of the dotted arrow in FIG. 26). Then, the powder particles that are guided by the powder collection blades 82 and reach the base end portion thereof are forcibly dropped by the auxiliary guide wall 81 into the small-diameter cylindrical portion 12 (powder particle discharge hole 12A).

 As shown in FIG. 21, a bottom wall 62 is detachably attached to the lower end portion of the small diameter cylindrical portion 12 in the powder drum 91. As shown in FIG. 27, the bottom wall 62 has a plurality of slits 62B (corresponding to the “particle passage hole” of the present invention) extending in a direction intersecting with the turning radius direction of the rotating member 80 in the container. ). Specifically, each slit 62B extends in a curved manner so as to approach the center of the bottom wall 62 in accordance with the urging force in the forward direction of the rotation direction of the container internal rotation member 80 (the direction of the thick arrow in FIG. 28). Yes.

 [0092] Each slit 62B of the bottom wall 62 is formed by adhering (crosslinking) the powder particles fed into the small-diameter cylindrical portion 12 by the container rotating member 80 (powder collection blade 82). In addition to being blocked by the arch, it is sized so that it can pass through with its granular arch collapsed. Also in this embodiment, a plurality of types of bottom walls 62 having different widths of the slit 301 are prepared, and the bottom wall 62 suitable for the granular material is selected and replaced before using the granular material measuring device 101. It becomes possible!

 As shown in FIG. 21, the bottom wall 62 is fixed to the lower end portion of the small-diameter cylindrical portion 12 by a fixed cylindrical body 50 screwed into the outer peripheral surface of the small-diameter cylindrical portion 12. As shown in FIG. 29, the fixed cylindrical body 50 has a structure in which a ring-shaped flange wall 50B protrudes inward from the lower end edge of the threaded cylinder part 50A that is screwed to the outside of the small diameter cylinder part 12. The outer edge portion of the bottom wall 62 is sandwiched in the plate thickness direction between the wall 50B and the step portion 12B formed on the inner peripheral edge at the lower end of the small diameter cylindrical portion 12. In addition, a bottom end cap 53 with a bottom end can be screwed onto the outer peripheral surface of the fixed cylindrical body 50, and the lower end cap 53 can seal the lower side of the bottom wall 62 (the lower end opening of the fixed cylindrical body 50). It has become. By attaching the lower end cap 53 in this manner, the powder drum 91 can be used as a storage container for the powder.

[0094] By the way, as shown in FIG. 25, the container internal rotating member 80 includes first and second arch crushing legs 85 and 86 extending downward from the shaft center plate 84, and removal of attached powder particles. Leg 87 And are provided. As shown in FIG. 21, both the first and second arch crushing legs 85, 86 and the attached powder granule removal leg 87 can be swung in the small diameter cylindrical portion 12 (powder particle discharge hole 12A). It is.

 [0095] The first arch crushing legs 85 are paired and are provided side by side with a space therebetween. The first arch crushing leg portion 85 extends downward from the base portion of the dust wing 83 of the axial center plate 84, and has a strip shape parallel to each other. The second arch crushing leg portion 86 extends downward from the root portion of the dust collection blade 82 of the shaft center plate 84, and as shown in FIG. 21, the width force seen from the front in the turning direction, the first arch. It is in the form of a strip that is wider than the grinding leg 85. These first and second arch crushing legs 85 and 86 are provided at positions 180 degrees apart from each other, and the downward force in the swiveling direction of the container internal rotation member 80 is reduced toward the lower side. It extends diagonally (more specifically, tilted about 30 degrees with respect to the vertical direction).

 [0096] The adhering granular material removal leg portion 87 hangs down from the base portion of the dust wing 83 to the bottom wall 62 of the axial center plate 84, and has substantially the same width as the first arch crushing leg portion 85. It has a strip shape. As shown in FIG. 26, when the in-container rotating member 80 rotates, the attached granular material removal leg portion 87 turns around the inner peripheral surface of the small diameter cylindrical portion 12. As a result, the granular material adhering to the inner peripheral surface of the small diameter cylindrical portion 12 due to static electricity or the like is scraped off.

 As shown in FIG. 21, the lengths of the first arch crushing legs 85 and the second arch crushing legs 86 are different, and the first arch crushing is performed when the container rotation member 80 rotates. While the lower end of the leg 85 pivots near the upper surface of the bottom wall 62 (a grazing that does not contact the upper surface of the bottom wall 62), the lower end of the second arch crushing leg 86 is the first arch crushing. Rotate above the lower end of leg 85. Then, the first and second arch crushing legs 85, 86 swivel above the bottom wall 62, so that the granular arch closing the slit 62B of the bottom wall 62 is subjected to external force and collapsed. It is discharged from the slit 62B.

Here, when the rotational speed of the in-container rotating member 80 is low, the granular material slips between the pair of first arch crushing legs 85, so that the first arch crushing legs 85 Only the granule arch at the part where the lower end of the part has passed can be broken down! / However, if the rotational speed is increased, it becomes difficult for the granule to pass between the first arch crushing legs 85. The part where the lower end of the first arch crushing leg 85 passed and the granular arch near it can be broken. [0099] Further, by extending the slit 62B in a direction intersecting the turning radius direction of the container internal rotating member 80, the first and second arch crushing legs 85, 86 are crossed over the slit 62B. Since the crossing distance becomes longer than the case where the slit is extended in the turning radius direction of the in-container rotating member 80, the granular arch can be broken in a wider range.

 [0100] In the present embodiment, the first arch crushing leg 85 and the lower end of the attached granular material removing leg 87 are chamfered so as to be rounded, whereas the second arch crushing. The lower end of leg 86 is squared (see Figure 25). Further, the first and second arch crushing legs 85 and 86 are formed by bending a sheet metal constituting the in-container rotating member 80, and the adhering granular material removing legs 87 are formed of the shaft plate 84. It is welded to the lower surface of. However, the in-container rotating member 80, which is not limited to this, may be a molded product of resin or rubber. This completes the description of the configuration of the powder and particle supply device 90.

 [0101] Next, the function and effect of the granular material supply device 90 of the present embodiment will be described.

 When the powder control disk 38 is rotationally driven by the supply motor 15, the powder on the powder control disk 38 flows from the annular space 94 to the horizontal step surface 21 by the powder discharge rod 39. I will give you. The granular material that has flowed down to the horizontal stepped surface 21 forms a granular particle pile having a predetermined angle of repose α 1 (see FIG. 22) with the granular material control disk 38.

 [0102] When the container rotating member 80 is rotationally driven by the supply motor 15, the powder collection blades 82 of the container rotating member 80 rotate while being in sliding contact with the horizontal step surface 21. At this time, the dust collection blade 82 scrapes off the pulverized fluid piles accumulated on the horizontal step surface 21 and feeds the granular material to the center of the horizontal step surface 21, that is, the small diameter cylindrical portion 12 (see FIGS. 22 and 22). 26).

 [0103] In addition, as soon as the powder particles are scraped off by the powder collection blades 82, the powder particles flow in from the annular space 94, and the horizontal difference between the powder control disc 38 and the horizontal step. A new pile of particles is formed between the wall 20 and the wall 20. In other words, the powder particles that have been scraped off by the powder collection blades 82 that do not collapse into the small diameter cylindrical portion 12 from the large diameter cylindrical portion 11 due to their own weight are only the small diameter cylindrical portion 12 (the granular material It is sent to the discharge hole 12A).

[0104] The granular materials fed into the small diameter cylindrical portion 12 adhere to each other to form a granular arch that closes the slit 62 ス リ ッ ト. This granular arch is a small diameter of the rotating member 80 in the container. Granules that have collapsed due to external force from the first arch crushing legs 85 and / or the second arch crushing legs 8 6 that swivel in the cylindrical part 12 and have formed the broken granular arch Physical strength S slit Fall from 62B. Also, as the powder falls, a new powder arch is immediately formed and the slit 62B is closed. Since the amount of the granular material flowing out from the slit 62B is very small before the granular material arch is formed again after the granular material arch is broken, the rotating member 80 in the container is swung at a constant speed. During the process, it is possible to supply a certain amount of granular material.

 By the way, when the in-container rotating member 80 (the first and second arch crushing legs 85, 86) is rotated at a relatively low speed, as shown in FIG. The lower edge force S of the first arch crushing leg 85 with a relatively small interval breaks the granule arch closing the slit 62B and breaks down the granule arch, while the interval with the bottom wall 62 is relatively large The lower end portion of the second arch crushing leg 86 passes only above the granular arch and does not give an external force enough to break the granular arch. This is because of the momentum of the powder that flows obliquely downward, that is, toward the upper surface of the bottom wall 62 (force to push the powder toward the upper surface of the bottom wall 62) by the guidance of the second arch crushing leg 86. Is small. Therefore, the granular material is discharged from the small diameter cylindrical portion 12 only when the first arch crushing leg portion 85 passes over the slit 62B.

 On the other hand, when the in-container rotating member 80 (first and second arch crushing leg portions 85 and 86) is rotated at a relatively high speed, the first arch as shown in FIG. In addition to the crushing leg 85, the second arch crushing leg 86 also applies an external force to the granular arch. This is due to the momentum of the powder that is guided by the second arch crushing leg 86 and that flows obliquely downward, that is, toward the upper surface of the bottom wall 62 (the granular material is moved toward the upper surface of the bottom wall 62). This is because the pushing force increases. Therefore, when the first arch crushing leg 85 passes over the slit 62B, and when the second arch crushing leg 86 passes over the slit 62B, the powder from the small-diameter cylindrical part 12 is removed. Discharged. That is, by changing the rotation speed of the inner rotating member 80 from a low speed to a high speed so that the powder arch is broken by both the first and second arch crushing legs 85 and 86, The amount of discharged particulate matter from the body supply device 90 can be increased rapidly.

[0107] When a predetermined amount, for example, 10 mg of powder is measured by the above-described powder particle measuring device 101 to the receiver 108, the following operation is performed. First, the receiver 108 is Place on weighing pan 102A and operate operation unit 102B to tare.

 Next, a target weight (for example, lOmg) of the granular material is set in advance in the control device 103 (corresponding to the “motor drive control unit” of the present invention), and a start switch (not shown) is turned on. Then, the measurement value of the measuring instrument 102 is fed back to the control device 103, and the rotation of the supply motor 15 is automatically turned on / off and the rotation speed is adjusted.

 [0109] For example, the control device 103 rotates the supply motor 15, that is, the in-container rotating member 80 at a relatively high speed until the measured value is before lOmg. At this time, since both the first and second arch crushing legs 85 and 86 break the powder arch, the discharge amount per unit time of the powder discharged from the powder supply device 90 is relatively high. The amount of powder and granule can be weighed to the level of lOmg in a short time. When the measured value is before lOmg, the control device 103 reduces the rotation speed of the supply motor 15, that is, the rotating member 80 in the container. Then, since only the first arch crushing leg 85 breaks the granular arch, the granular material is discharged little by little, and the measured value can be gradually brought close to lOmg. Then, when the measured value reaches 1 Omg, the control device 103 stops the rotation of the supply motor 15.

 [0110] Thus, according to the granular material supply device 90 of the present embodiment, both the first and second arch crushing legs 85 and 86 are rotated when the in-container rotating member 80 is rotated at a high speed. Break up the powder arch and supply a relatively large amount of powder, and when rotating at low speed, only the first arch crushing leg 85 will break the powder arch and supply a small amount of powder. Therefore, it is possible to accurately and promptly measure the target weight of the granular material.

 [0111] [Other Embodiments]

 The present invention is not limited to the above-described embodiments.
