A torque transmission shaft 15 is provided below the rotation output shaft 14A at the center of the powder supply cylinder 11, and the upper end of the torque transmission shaft 15 is connected to the rotation output shaft 14A via a coupling 14B. . Further, the lower end portion of the torque transmission shaft 15 slightly protrudes from the lower end opening 20A of the granular material supply cylinder 11, and the rotating disk 50 is attached to the lower end surface thereof.

  The turntable 50 has a structure in which a thin dish portion 50B is integrally formed on the upper surface of a flat cylindrical body 50A. And the dish part 50B among the turntables 50 is addressed to the lower end opening 20A of the granular material supply cylinder 11, and is in a state of projecting laterally from the small diameter cylindrical part 20 of the granular material supply cylinder 11. . The lower end surface of the torque transmission shaft 15 is in surface contact with the center of the bottom surface of the plate portion 50 </ b> B, and a bolt 15 </ b> E penetrating the center of the rotating plate 50 is fastened to the torque transmission shaft 15 in the screw hole of the core portion. Thereby, the lower end surface of the rotating disk 50 and the bottom surface of the torque transmission shaft 15 are frictionally engaged with each other, and when the torque transmission shaft 15 is rotationally driven by the motor 14, the rotating disk 50 rotates integrally with the torque transmission shaft 15. .

  Further, the rotating disk 50 is driven to rotate in the direction opposite to the tightening direction of the bolt 15E by the motor 14. Specifically, as shown in FIG. 12 (A), the rotating disk 50 is rotationally driven in the clockwise direction in FIG. This prevents loosening of the bolt 15E.

A pile of accumulated powder particles (see symbol “M” in FIG. 2) is formed, and the lower end side opening 21 is closed by the pile of the powder particles.

  The torque transmission shaft 15 is shown in FIG. 3 as a whole. For example, the upper end portion of a prismatic body having a regular hexagonal cross section is cut into a cylindrical shape to include an upper end cylindrical portion 15A, and the position closer to the upper end is set in the axial direction. It has a structure provided with an intermediate cylindrical portion 15C by cutting into a cylindrical shape over a slight range. The upper end cylindrical portion 15A is connected to the rotation output shaft 14A of the motor 14 through the coupling 14B as described above. Further, a first shaft mounting component 45 (corresponding to the “stirring member” of the present invention) shown in FIG. 4 is mounted on the intermediate cylindrical portion 15C, and an upper prism portion 15B above the intermediate cylindrical portion 15C is mounted on The second shaft mounting component 40 (corresponding to the “inner turning guide member” of the present invention) shown in FIG. 5 is mounted.

  As shown in FIG. 4, the first shaft mounting component 45 is formed by integrally forming a stirring bar 47 on the E ring portion 45 </ b> R. The E-ring portion 45R normally has the same structure as the E-ring used for preventing the shaft component from coming off, and has three protrusions on the inner peripheral surface of the ring that is partially cut away. Further, the stirring bar 47 extends downward from a portion of the E-ring portion 45R that faces the notch 45A. The E-ring portion 45R is attached to the intermediate cylindrical portion 15C from the side, and the stirring bar 47 extends in parallel with the lower prism portion 15B below the intermediate cylindrical portion 15C of the torque transmission shaft 15.

  On the other hand, as shown in FIG. 5, the second shaft mounting part 40 is positioned at a position equally divided into three in the circumferential direction of the prismatic fitting ring 40 </ b> R fitted and attached to the torque transmission shaft 15 and the prismatic fitting ring 40 </ b> R.

It is inserted into the square hole 40A. Accordingly, as shown in FIG. 7, the prismatic fitting ring 40 </ b> R abuts on the first shaft mounting component 45 and is positioned in a state where the polygonal hole 40 </ b> A is fitted to the intermediate cylindrical portion 15 </ b> C of the torque transmission shaft 15. The second shaft mounting component 40 rotates integrally with the torque transmission shaft 15 by the engagement between the portion 15C and the prismatic fitting ring 40R. In addition, the locking piece 43 hangs downward from the outer edge of the prismatic fitting ring 40R and fits into the notch 45A of the first shaft mounting component 45, and the second shaft mounting component 40 and the first shaft mounting component 45 Are connected so that they can rotate together. Then, when the first shaft mounting component 45 rotates together with the torque transmission shaft 15 and the second shaft mounting component 40, the stirring bar 47 of the first shaft mounting component 45 is moved by the small-diameter cylindrical portion 20 of the granular material supply cylinder 11. Prevents the formation of grain bridges.

  The powder collecting arm 41 projects in a radial direction from the outer edge of the prismatic fitting ring 40R, and its tip end is bent and extended at a substantially right angle toward the locking piece 43 in the horizontal plane, and its tip is engaged in the horizontal plane. It has a structure slightly bent toward the stop piece 43 side. Further, the tip of the powder collecting arm 41 reaches a position in the vicinity of the inner surface of the large-diameter cylindrical portion 12 in the granular material supply cylinder 11. When the torque transmission shaft 15 is rotationally driven by the motor 14, the tip of the powder collecting arm 41 precedes, and the granular material at the bottom of the large diameter cylindrical portion 12 is scraped together by the entire powder collecting arm 41 to form a small diameter cylinder.

  The stirring protrusion 44 protrudes in the radial direction from the outer edge portion of the prismatic fitting ring 40R and extends to the upper end opening edge of the small diameter cylindrical portion 20 (see FIG. 6). And it prevents that the bridge | bridging of a granular material is formed in the upper-end opening of the small diameter cylindrical part 20. FIG. Since the torque transmission shaft 15 as a whole has a prismatic structure, the corners of the torque transmission shaft 15 prevent the powder particles in the powder particle supply cylinder 11 from being agitated to form a bridge.

  As shown in FIG. 8, an annular bracket 25 corresponding to both the “rotating bracket” and the “linear motion bracket” of the present invention is attached to the lower end portion of the granular material supply cylinder 11. As shown in FIG. 9, the annular bracket 25 has an annular shape with a fastening hole 25 </ b> A at the center, and a part in the circumferential direction is cut out in a slit shape. The annular bracket 25 is attached with an adjustment bolt 25B (corresponding to the “rotating bracket fixing means” and the “linear bracket fixing means” according to the present invention) so as to straddle the above-described notch, By changing the tightening amount of the annular bracket 25, the tightening hole 25A expands and contracts. And the small diameter cylindrical part 20 of the granular material supply cylinder 11 is fitted in the tightening hole 25A, and the annular bracket 25 is rotated up and down with respect to the small diameter cylindrical part 20 with the adjustment bolt 25B loosened. The annular bracket 25 can be fixed to the small-diameter cylindrical portion 20 by being arranged at an arbitrary position and closing the adjusting bolt 25B at the arbitrary position.

  A part of the outer surface of the annular bracket 25 is cut flat, and the powder body guide member 60 is fixed thereto. The granular material guide member 60 includes a flat plate portion 61 addressed to the outer surface of the annular bracket 25. The flat plate portion 61 includes a pair of elongated holes 61A extending in the lateral direction as shown in FIG. 61A is formed. And the granular material guide member 60 is being fixed to the annular bracket 25 with the volt | bolt 26 (refer FIG. 8) penetrated by these long holes 61A and 61A.

  The lower end edge of the flat plate portion 61 has a stepped shape, and a guide rail 63 extends in a horizontal direction from the stepped portion. As shown in FIG. 11, the guide rail 63 extends from a position outside the outer edge of the turntable 50 toward the outer surface of the powder supply cylinder 11, and the guide rail 63 extends laterally from the powder supply supply 11 in the turntable 50. It is addressed from above to the overhanging part. And when the granular material deposited on the upper surface of the rotating disk 50 moves to the guide rail 63 side by the rotation of the rotating disk 50, the granular material is guided to drop downward from the outer edge of the rotating disk 50. To do.

  Specifically, the portion of the guide rail 63 that extends from the base end portion on the flat plate portion 61 side to the intermediate portion is on the outer surface of the granular material supply cylinder 11 in the horizontal plane, as shown in FIG. It extends in the tangential direction of a certain circular arc surface. In addition, the base end portion of the guide rail 63 is positioned on the front side in the rotation direction of the rotating disc 50 from the tip end portion of the guide rail 63, and the base end portion of the guide rail 63 is an outer edge from the outside of the rotating disc 50. The upper surface 50J of the annular protruding wall 50H is traversed. As a result, when the rotating disk 50 rotates, the granular material in contact with the distal end side of the guide rail 63 is guided to the proximal end side and guided so as to drop downward from the outer edge portion of the rotating disk 50. it can.

  As shown in FIG. 11, the lower surface 63B of the guide rail 63 is a horizontal flat surface, and the lower surface 63B is in surface contact with the upper surface 50J of the outer peripheral annular protruding wall 50H so as to be slidable. As a result, when the turntable 50 rotates, the guide rail 63 leveles the granular material deposited inside the outer edge annular projecting wall 50H so as to be flush with the upper surface 50J of the outer edge annular projecting wall 50H. Thereby, as described above, an “always deposited layer” is formed on the rotating disk 50. In addition, by adjusting the position of the annular bracket 25 in the vertical direction with respect to the small diameter cylindrical portion 20, the sliding contact state between the guide rail 63 and the outer edge annular protruding wall 50H can be adjusted to a suitable state.

  The distal end portion of the guide rail 63 is a movable door 64 according to the present invention, and the movable door 64 is curved in an arc shape and is in surface contact with the outer peripheral arc surface which is the outer surface of the small diameter cylindrical portion 20. . Further, the movable door 64 projects upward from the entire guide rail 63 as shown in FIG. The movable door 64 can change the opening area of the lower end side opening 21. That is, by rotating the annular bracket 25 with respect to the small-diameter cylindrical portion 20, the opening area of the lower end side portion opening 21 is changed as shown in FIGS. 12A and 12B. be able to. In order to allow the movable door 64 to come into surface contact with the outer peripheral circular arc surface, which is the outer surface of the small-diameter cylindrical portion 20, the flat plate portion 61 is positioned relative to the annular bracket 25 in the longitudinal range of the long hole 61 </ b> A. Adjust it.

  A side slidable contact member 62 is provided at the lower end portion of the flat plate portion 61 in the granular material guide member 60. The side-sliding contact member 62 protrudes downward from the lower surface 63B of the guide rail 63 and is disposed on the front side of the powder guide member 60 in the rotational direction of the rotating disk 50. Then, one end portion of the side surface sliding contact member 62 comes into contact with the vertical outer side surface 50S of the turntable 50 so as to be slidable from the side, and as shown in FIG. Is standing in the radial direction from the vertical outer surface 50S of the rotating disk 50. Then, when the powder particles that have fallen downward from the outer edge of the turntable 50 by the guide rail 63 adhere to the vertical outer side surface 50S of the turntable 50, they are scraped off by this side sliding contact member 62. ing.

  The description regarding the structure of the granular material supply apparatus 10 of this embodiment is above. Next, the effect is demonstrated. In a state where the rotation of the turntable 50 in the granular material supply apparatus 10 is stopped, the granular material in the granular material supply cylinder 11 flows out from the lower end side opening 21 of the granular material supply cylinder 11 to the side. A pile of powder particles (see symbol “M” in FIG. 2) having an angle of repose (see symbol “α” in FIG. 2) is formed, and the pile of powder particles is held in a fixed shape without collapsing. This prevents the granular material from continuously flowing out from the lower end side opening 21.

  When the rotating disk 50 is rotationally driven by the motor 14, the pile of powder particles that have closed the lower end side opening 21 collapses and flows down so as to spread on the rotating disk 50, and the granular materials corresponding to the collapsed particles. Is supplied to the lower end side opening 21 so that the powder is supplied. Thus, while the rotating disk 50 continues to rotate, an amount of powder corresponding to the rotation speed flows out from the lower end side opening 21 onto the rotating disk 50. Here, when the granular material flows out from the lower end side opening 21 of the granular material supply cylinder 11, the granular material receives a force between the granular material supply cylinder 11 and the rotating disk 50, so that the aggregate of the granular material Even if there is, it is crushed and a very small amount of powder can be discharged onto the rotating disk 50 from the lower end side opening 21.

  The granular material discharged onto the turntable 50 is pressed against the guide rail 63 by the rotation of the turntable 50, falls from the outer edge of the turntable 50 by the guide rail 63, and is placed below the container 104 ( 1). Here, since the granular material receives a force between the guide rail 63 and the rotating disk 50 in the process of being guided by the guide rail 63, even if there is an aggregate of the granular material, it is crushed, Granules can be supplied to the container 104 below the turntable 50.

  Thus, in the granular material supply apparatus 10 of this embodiment, a trace amount granular material can be continuously supplied conventionally. Moreover, the supply amount of a granular material can be changed by changing the rotational speed of the turntable 50 by the motor 14. If the rotation speed of the turntable 50 is set to an arbitrary constant speed, an arbitrary fixed amount of powder particles can be supplied minutely and accurately.

  Moreover, since the opening area of the lower end side part opening 21 can be changed by the movable door 64 provided in the lower end side part opening 21, the supply amount of the granular material can also be changed by the lower end side part opening 21. . Then, by appropriately changing both the rotational speed of the motor 14 and the opening area of the lower end side opening 21, the appropriate amount can be freely adjusted with respect to the desired supply amount. Furthermore, by changing the opening area of the lower end side opening 21 by the movable door 64, the opening area is set so that an optimum peak of the granular material is formed in the lower end side opening 21 according to the type of the granular material. It can also be adjusted.

Thereby, when dropping a granular material downward from the turntable 50 and supplying it to a container etc., the motor 14 does not get in the way and the usability of the granular material supply apparatus 10 is improved. In addition, the granular material is agitated in the granular material supply cylinder 11 using the torque transmission shaft 15 for transmitting the torque of the motor 14 to the rotating disk 50, and the granular material in the granular material supply cylinder 11. Bonding between each other can be prevented.

  In addition, since the outer edge annular protruding wall 50H is formed on the turntable 50, a constantly deposited layer (see reference numeral “Z” in FIGS. 1 and 2) is maintained on the turntable 50, and the guide layer 63 and the guide rail 63 are formed by the always deposited layer. It is possible to prevent the phenomenon that the powder particles are caught between the rotating disk 50 and the rotation of the rotating disk 50 is stabilized. And only the part which protruded to the guide rail 63 side among the deposit layers of a granular material can be guided with the guide rail 63, and can be supplied to the container 104 below from the turntable 50. FIG. Furthermore, since the lower edge taper portion 50T is formed by tapering the outer edge portion of the turntable 50 downward, the granular material dropped from the outer edge portion of the turntable 50 adheres to the side surface and the lower portion of the turntable 50. Can be prevented.
