The powder mixing device (1) disclosed in Patent Document 1 has a processing tank (2), a rotating member (3), and a rotating mechanism (4). The treatment tank (2) has a top plate member (21), a peripheral wall member (22), and a bottom plate member (23). The peripheral wall member (22) has a cylindrical cylindrical peripheral wall (221) and an inverted conical conical peripheral wall (222) connected to a lower end portion of the cylindrical peripheral wall (221). The top plate member (21) closes the opening at the upper end of the peripheral wall member (22). The bottom plate member (23) closes the opening at the lower end of the peripheral wall member (22). The powder of the object to be processed is charged into the processing space (S) surrounded by these through the input port (26) provided in the top plate member (21). Further, the rotating member (3) has a shaft portion (31) and a stirring blade (32). When the rotating mechanism (4) having the motor (42) is driven, the shaft portion (31) and the stirring blade (32) rotate.

Further, a guide member (25) is provided above the stirring blade (32) in the processing space (S). The guide member (25) has a hanging rod (251) extending in the vertical direction and a guide plate (252) fixed to the lower end of the hanging rod (251).

It has a guide unit 50, a control unit 60, and a base unit 70.

FIG. 3 is a side view showing a part of the covered powder or granular material storage container 10 conceptually. As shown in FIG. 3, the covered powder or granular material container 10 has a bottomed tubular container body 11 and an upper lid 12. The container body 11 and the upper lid 12 of the present embodiment are each made of a metal material such as stainless steel.

The container body 11 has a plate-shaped bottom plate portion 111 and a tubular side wall portion 112. The bottom plate portion 111 has a substantially perfect circular shape when viewed from above. The side wall portion 112 extends upward from the outer peripheral portion of the bottom plate portion 111 along the first central axis 91 extending in the vertical direction. That is, the container body 11 of the present embodiment has a bottomed cylindrical shape. Further, an opening 110 is provided in the upper part of the container body 11.

The upper lid 12 is a plate-shaped member that covers the opening 110 of the container body 11. When the powder or granular material is stirred and mixed, the powder or granular material is housed in the internal space 100 of the container body 11, and the opening 110 is closed by the upper lid 12. A sealing member such as an O-ring that contacts the upper end surface of the side wall portion 112 may be provided on the lower surface of the upper lid 12. Further, as shown in FIG. 3, the upper lid 12 is provided with a through hole 120. The through hole 120 penetrates the upper lid 12 in the vertical direction at a position separated from the center 121 (the intersection of the upper lid 12 and the first central axis 91) in the upper view of the upper lid 12.

The upper lid support mechanism 13 has an upper lid support mechanism main body 131 and an upper lid support mechanism arm 132. The upper lid support mechanism main body 131 extends in the vertical direction and is fixed to the base 70 (see FIG. 1) at the lower end. One end of the upper lid support mechanism arm portion 132 is fixed to the upper lid support mechanism main body 131, and is supported so as to be rotatable and vertically movable with respect to the upper lid support mechanism main body 131. The other end of the upper lid support mechanism arm portion 132 is fixed to the upper lid 12.

Since the upper lid support mechanism 13 has the above configuration, the upper lid 12 is laterally movablely supported between the closed position Pc that closes the opening 110 and the open position Po that opens at least a part of the opening 110. (See arrow A1 in FIG. 2). More specifically, the open position Po is located diagonally above the front of the closed position Pc. As a result, at the open position Po, a part of the upper lid 12 projects forward of the container body 11.

The stirring member 20 is a member for stirring and mixing the powder or granular material contained in the internal space 100 of the container body 11. The stirring member 20 is located near the bottom of the internal space 100. The stirring member 20 has a plurality of stirring blades 21. The plurality of stirring blades 21 are provided around the shaft 33, which will be described later. When the stirring member 20 is rotated, an air flow is generated in the internal space 100 of the container body 11 along the circumferential direction (first circumferential direction) centered on the first central axis 91. In the present embodiment, two stirring members 20 having different shapes are arranged in a state of being stacked in the vertical direction. However, the number of the stirring members 20 may be one or three or more.

The drive unit 30 is a mechanism for rotating the stirring member 20. As conceptually shown in FIG. 1, the drive unit 30 includes a motor unit 31 (motor and speed reducer) as a drive source, a power transmission mechanism 32, and a shaft 33. The shaft 33 penetrates the bottom plate portion 111 of the container body 11 and extends in a columnar shape in the vertical direction along the first central axis 91. The upper end of the shaft 33 is connected to the center of the stirring member 20. The power transmission mechanism 32 transmits the driving force output from the motor unit 31 to the shaft 33. As the power transmission mechanism 32, for example, a mechanism having a pair of pulleys and an annular timing belt hung on the pulleys is used. However, the power transmission mechanism 32 may be another mechanism. Further, the output shaft of the motor unit 31 may be directly connected to the shaft 33 without going through the power transmission mechanism 32.

The shaft 33 is rotatably supported by a bearing (not shown) interposed between the shaft 33 and the bottom plate portion 111. Further, as conceptually shown in FIG. 3, the powder or granular material processing device 1 includes an air seal mechanism 34 for introducing a gas between the bottom plate portion 111 and the shaft 33. The air seal mechanism 34 introduces the gas pressurized by the compressor into the internal space 100 of the container body 11 via the space between the bottom plate portion 111 and the shaft 33. As a result, the powder or granular material contained in the internal space 100 is prevented from leaking to the outside from between the bottom plate portion 111 and the shaft 33.

The powder or granular material discharge unit 40 is a mechanism for discharging the powder or granular material after stirring and mixing. The powder or granular material discharge unit 40 has a discharge port 41, a discharge path 42, and a discharge valve 43. The discharge port 41 is an opening provided near the lower end of the side wall portion 112. The discharge port 41 is located outside the stirring member 20 in the radial direction. The discharge path 42 extends diagonally downward from the discharge port 41. The discharge valve 43 switches the discharge port 41 between a closed state and an open state. When the powder or granular material is stirred and mixed in the internal space 100 of the container body 11, the discharge valve 43 closes the discharge port 41. Further, when the processing is completed, the discharge valve 43 opens the discharge port 41. As a result, the powder or granular material stored in the internal space 100 is discharged to the discharge path 42 through the discharge port 41. However, the powder or granular material discharging unit 40 does not necessarily have to be provided. For example, a plurality of types of powders and granules may be charged through the opening 110 of the container body 11, stirred and mixed, and then taken out from the opening 110 again.

The guide portion 50 is a mechanism including a guide plate 52 that controls the flow of the powder or granular material that is agitated by the rotation of the agitating member 20 in the internal space 100 of the container body 11. The detailed structure of the guide unit 50 will be described later.

The control unit 60 is a unit for controlling the operation of each part of the powder or granular material processing device 1. The control unit 60 is composed of, for example, an electric circuit board. However, the control unit 60 may be configured by a computer. The control unit 60 of the present embodiment is electrically connected to the motor unit 31 and the discharge valve 43, respectively. Further, the control unit 60 has a storage unit 61. The control unit 60 operates the motor unit 31 and the discharge valve 43 based on various conditions stored in the storage unit 61. As a result, the stirring and mixing treatment and the discharge treatment of the powder or granular material in the powder or granular material processing apparatus 1 proceed. However, the control unit 60 does not necessarily have to be provided. The motor unit 31 and the discharge valve 43 may be manually operated by an operator.

The base portion 70 is a frame body that accommodates the power transmission mechanism 32 of the drive portion 30 and a part of the shaft 33. Further, a covered powder or granular material storage container 10 is arranged and fixed on the upper surface 701 of the base portion 70.

<1-2. Detailed structure of the guide>
Subsequently, the detailed structure of the guide unit 50 will be described. FIG. 4 is a partial vertical cross-sectional view of the vicinity of the guide portion 50 in the powder or granular material processing apparatus 1. As shown in FIG. 4, the guide portion 50 includes a support shaft 51, a guide plate 52 (see FIG. 3), a fixing portion 53, a first movable portion 54, a second movable portion 55, a cover portion 56, and a tightening bolt 57 (lock).

However, the support shaft 51 may extend in a columnar shape in the vertical direction along the second central shaft 92. As shown in FIGS. 1 and 3, the support shaft 51 extends to the vicinity of the lower part of the internal space 100 of the container body 11. Further, the guide plate 52 is fixed to the support shaft 51 in the internal space 100 of the container body 11. In the present embodiment, the guide plate 52 is located above the stirring member 20.

FIG. 5 is a top view of the guide unit 50. In FIG. 5, a part of the side wall portion 112 is shown by a broken line in order to clarify the positional relationship between the guide plate 52 and the inner peripheral surface 113 of the side wall portion 112 in the internal space 100 of the container body 11. .. As shown in FIG. 5, the guide plate 52 has a substantially crescent shape when viewed from above. The guide plate 52 is inclined with respect to the flow of the powder or granular material along the first circumferential direction generated by rotating the stirring member 20. Therefore, when the stirring member 20 rotates while the powder or granular material is housed in the internal space 100 of the container body 11, a part of the powder or granular material collides with the guide plate 52. Thereby, the direction of the flow of the powder or granular material can be controlled. Then, by adjusting the amount of the powder or granular material passing through the gap between the guide plate 52 and the inner peripheral surface 113 of the side wall portion 112, stirring suitable for the physical properties of the powder or granular material can be realized.

The fixed portion 53 has a fixed-side bent portion 531 that extends cylindrically along the second central axis 92 and bends outward in the second radial direction at the lower end portion. The fixing portion 53 is arranged on the upper surface of the mounting portion 122. The lower surface of the fixing portion 53 is fixed to the upper surface of the mounting portion 122 by, for example, bolts (not shown). However, the fixing portion 53 may be fixed to the upper surface of the upper lid 12 by welding or the like. Further, the fixed-side bent portion 531 has a plate-shaped portion 532 that further protrudes outward in the second radial direction in a plate-like shape in a part in the second circumferential direction. The plate-shaped portion 532 is provided with a bolt hole 533. The bolt hole 533 is provided in the plate-shaped portion 532 from the upper surface to the lower side. Further, as shown in FIG. 4, a seal member 534 is provided over the entire circumference between the inner peripheral surface of the fixing portion 53 and the outer peripheral surface of the support shaft 51.

The first movable portion 54 extends in an annular plate shape around the second central axis 92. The first movable portion 54 is arranged on the upper surface of the upper end portion of the fixed portion 53. A support shaft 51 is inserted inside the first movable portion 54 in the radial direction, and is fixed by, for example, press fitting. However, the support shaft 51 may be fixed to the inside of the first movable portion 54 in the radial direction by adhesion or welding. Further, as shown in FIGS. 4 and 5, the lever 58 is fixed at a predetermined position in the second peripheral direction of the outer peripheral portion of the first movable portion 54.

As shown in FIG. 4, the second movable portion 55 has a cylindrical shape along the second central axis 92. The second movable portion 55 is arranged on the upper surface of the fixed side bent portion 531 of the fixed portion 53. The upper surface of the second movable portion 55 is fixed to the lower surface of the first movable portion 54 by using a screw 541. However, the second movable portion 55 may be fixed to the first movable portion 54 by adhesion or welding. The second movable portion 55 has a movable side bent portion 551 that bends outward in the second radial direction in a part of the lower end portion in the second circumferential direction.

As shown in FIG. 5, the movable side bent portion 551 is provided with an elongated hole 552. The elongated hole 552 extends in the second circumferential direction in a predetermined angle range θ about the second central axis 92 while penetrating the movable side bent portion 551 in the vertical direction. Further, the width of the elongated hole 552 in the second radial direction is slightly larger than the outer diameter of the shaft portion 571 described later of the tightening bolt 57. A plurality of scales 553 are engraved on the inside of the elongated hole 552 in the second radial direction on the upper surface of the movable side bent portion 551. The plurality of scales 553 are arranged in the second circumferential direction with the second central axis 92 as the center. However, the position where the scale 553 is engraved may be outside of the movable side bent portion 551 in the second radial direction of the elongated hole 552, and the surface of the movable side bent portion 551 facing the elongated hole 552 (long hole formation). It may be surface 554 (see FIG. 4)).

The cover portion 56 extends in a cylindrical shape along the second central axis 92. The cover portion 56 is arranged on the upper surface of the first movable portion 54. The lower surface of the cover portion 56 is fixed to the upper surface of the first movable portion 54 by, for example, bolts (not shown). However, the cover portion 56 may be fixed to the first movable portion 54 by welding or the like.

A tightening bolt 57 is tightened and fixed in the bolt hole 533 of the fixing portion 53. At this time, the shaft portion 571 of the tightening bolt 57 penetrates the elongated hole 552 of the movable side bent portion 551, and the lower end portion is fitted into the bolt hole 533. Further, a washer 535 is arranged between the head portion 572 of the tightening bolt 57 and the movable side bent portion 551. In a state where the tightening bolt 57 is tightened and fixed in the bolt hole 533, the second movable portion 55 including the movable side bending portion 551, the first movable portion 54 fixed to the second movable portion 55, and the first movable portion 54 The cover portion 56 and the lever 58 fixed to the container, the support shaft 51 fixed to the inside of the first movable portion 54 in the radial direction, and the guide plate 52 fixed to the support shaft 51 in the internal space 100 of the container body 11 I can't move.

As described above, the lever 58 is fixed to the first movable portion 54. Further, a support shaft 51 is fixed inside the first movable portion 54 in the radial direction. That is, the lever 58 is indirectly fixed to the support shaft 51 via the first movable portion 54 on the outside of the covered powder or granular material storage container 10. However, the lever 58 may be directly fixed to the support shaft 51 on the outside of the covered powder or granular material storage container 10. The lever 58 extends in the second radial direction, and a spherical grip portion 581 is attached to the outer end portion in the second radial direction. As a result, the operator can easily operate the lever 58 by grasping the grip portion 581.

In a state where the tightening bolt 57 is loosened to the bolt hole 533, the second movable portion 55 including the movable side bent portion 551, the first movable portion 54 fixed to the second movable portion 55, and the first movable portion 55. The cover portion 56 and the lever 58 fixed to the portion 54, the support shaft 51 fixed to the inside of the first movable portion 54 in the radial direction, and the guide plate 52 fixed to the support shaft 51 in the internal space 100 of the container body 11. Can rotate integrally around the second central axis 92. However, when the elongated hole forming surface 554 of the movable side bent portion 551 comes into contact with the tightening bolt 57, it cannot move any further. Normally, the tightening bolt 57 is not moved in the horizontal direction with the lower end inserted into the bolt hole 533. As described above, the elongated hole 552 extends in the second circumferential direction in a predetermined angle range θ centered on the second central axis 92. As a result, the second movable portion 55 including the movable side bending portion 551, the first movable portion 54, the cover portion 56, the lever 58, the support shaft 51, and the guide plate 52 are predetermined with the second central shaft 92 as the center. It becomes rotatable in the angle range θ. As a result, in a state where the tightening bolt 57 is loosened to the bolt hole 533, the lever 58 rotates about the second central shaft 92 together with the support shaft 51, so that the side wall portion 112 of the container body 11 The inclination angle of the guide plate 52 with respect to the above can be changed.

As described above, in a state where the tightening bolt 57 is loosened to the bolt hole 533, the second movable portion 55 including the movable side bent portion 551 becomes rotatable about the second central shaft 92. The lower end of the tightening bolt 57 is maintained in a state of being fitted into the bolt hole 533. Therefore, when the worker operates the lever 58 to rotate the support shaft 51 and the movable side bent portion 551 around the second central shaft 92 (see arrow A2 in FIG. 5), the movable side bent portion 551 is tightened. The relative position of the attached bolt 57 about the second central axis 92 is changed.

Here, as described above, a plurality of scales 553 are engraved on the inside of the elongated hole 552 in the second radial direction on the upper surface of the movable side bent portion 551. Therefore, by confirming the position of the tightening bolt 57 with respect to the scale 553, how much the movable side bent portion 551 has rotated about the second central shaft 92, and further, the guide plate 52 attached to the support shaft 51. The inclination angle of the container body 11 with respect to the side wall portion 112 can be confirmed. That is, in the present embodiment, the scale is engraved by the movable side bending portion 551 and the tightening bolt 57 along the rotation direction of the support shaft 51 with respect to the second central shaft 92 on the outside of the covered powder or granular material storage container 10. An "angle position display unit" including 553 is formed. Then, by using the "angle position display unit", the inclination angle of the guide plate 52 with respect to the side wall portion 112 of the container body 11 can be grasped on the outside of the covered powder or granular material storage container 10 without opening the upper lid 12. Can be done.

Further, as shown in FIG. 4, a temperature sensor 59 is arranged inside the support shaft 51 of the present embodiment in the second radial direction. A part including the lower end of the temperature sensor 59 is located in the internal space 100 of the container body 11. The temperature sensor 59 is a sensor that detects the temperature of the internal space 100. Specifically, the temperature sensor 59 is composed of, for example, a thermocouple. The temperature sensor 59 is fixed to the support shaft 51 near the upper end portion. With such a configuration, for example, the temperature of the internal space 100 of the container body 11 can be detected without separately securing a space for arranging the temperature sensor 59 on the upper lid 12.

The outline of the method of adjusting the inclination angle of the guide plate 52 with respect to the side wall portion 112 of the container main body 11 by using the guide portion 50 of the present embodiment will be described below. First, the upper lid 12 is opened, and a plurality of types of powders and granules are put into the internal space 100 through the opening 110 of the container body 11, and then the upper lid 12 is closed. After that, the tightening bolt 57 is loosened. Then, while checking the "angle position display portion" including the movable side bending portion 551 having the scale 553 and the tightening bolt 57, the lever 58 is operated to operate the lever 58 together with the second bending portion 551 including the movable side bending portion 551. The movable portion 55, the first movable portion 54, the support shaft 51, the cover portion 56, and the guide plate 52 are rotated around the second central shaft 92. Then, when the tightening bolt 57 is at an appropriate relative position with respect to the scale 553, the operation of the lever 58 is stopped. After that, the tightening bolt 57 is tightened and fixed in the bolt hole 533.

As described above, in the present embodiment, by tightening and fixing the tightening bolt 57 to the bolt hole 533 of the fixing portion 53, the second movable portion 55 including the movable side bending portion 551, the first movable portion 54, and the support shaft It is possible to limit the rotation of the 51, the cover portion 56, the lever 58, and the guide plate 52 about the second central shaft 92. As a result, for example, it is possible to prevent an operator from erroneously operating the lever 58 and unexpectedly shifting the inclination angle of the guide plate 52 in the internal space 100 of the container body 11. That is, in the present embodiment, the tightening bolt 57 has a function as a "lock member" that limits the rotation of the lever 58 about the central axis. However, as the "lock member", a handle or the like that restricts the movement of the lever 58 may be used.

<2. Modification example>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

In the above embodiment, in a state where the tightening bolt 57 is loosened, the second movable portion 55 including the movable side bending portion 551 having the scale 553 can rotate about the second central axis 92. On the other hand, the tightening bolt 57 has a structure in which the lower end thereof is maintained in a state of being fitted into the bolt hole 533 and cannot be moved in the horizontal direction. However, the subject of the present invention is not limited to such a structure. For example, it has a structure in which the horizontal movement of a member having a scale is restricted, while the relative positions of bolts and the like are changed by rotating around a second central axis together with a support axis. May be good.

In the above embodiment, the upper lid 12 is supported by the upper lid support mechanism 13 so as to be laterally movable between the closed position Pc that closes the opening 110 and the open position Po that opens at least a part of the opening 110. It was. However, the upper lid 12 may have a structure that opens upward, or may have a structure that can be attached to and detached from the container body 11.

The detailed configuration of the powder or granular material processing apparatus may be different from the configuration shown in each figure of the present application. Further, the elements appearing in the above-described embodiments and modifications may be appropriately combined as long as there is no contradiction.
