The valve 128 shown as a cone valve in FIG. 4 may be a butterfly valve or the like provided with a vibrator. An appropriate drive source such as a fluid pressure drive source or an electric drive source can be used for opening and closing the valve body of the valve 128. The valve moving means is built in the holding member 116 and may consist of a combination of a ball screw and a motor or a fluid pressure cylinder.

The powder processing performed in the powder processing apparatus as described above will be described. Explaining with reference to FIG. 1, the container 2 containing the powder P and whose opening 20 is closed by the lid 22 is moved to the mixer 4 by an appropriate moving means 132 such as a chain conveyor or a roller conveyor. The container 2 is temporarily stopped in front of the mixer 4, and the lid 22 is removed from the container 2 by an appropriate lid attachment / detachment means 134. As shown in FIG. 1, for example, the lid attachment / detachment means 134 is attached to a pair of air cylinders 136 that are vertically arranged so as to be able to move up and down, a raising / lowering means (not shown) that raises and lowers each air cylinder 136, and each air cylinder 136. It may be provided with a locked locking piece 138. When removing the lid 22 from the container 2 by the lid attachment / detachment means 134, first, each air cylinder 136 is lowered by the raising / lowering means of the lid attachment / detachment means 134, and the locking piece 138 is positioned on the side of the lid 22. Next, each air cylinder 136 is operated to lock the locking piece 138 to the lid 22. Next, the lid 22 can be removed from the container 2 by raising each air cylinder 136 together with the locking pieces 138 locked to the lid 22 by the raising and lowering means of the lid attaching / detaching means 134. The empty container 2 was moved by the moving means 132, one or more kinds of powder was put into the container 2 through the opening 20 in front of the mixer 4, and the powder having a predetermined total mass was contained in the container 2. This may be weighed by the weighing machine 140.

After removing the lid 22 from the container 2 containing the powder P, the container 2 is moved by the moving means 132, and the container 2 is mounted on the mounting base 84 of the mixer 4 as shown in FIG. When mounting the container 2 on the mounting base 84, the flange 18 of the container 2 is positioned directly below the closing piece 68. Next, the upper surface of the flange 18 of the container 2 hits the lower surface of the closing piece 68 from the separated position (position shown in FIG. 5) at which the upper surface of the flange 18 of the container 2 (the upper end of the container 2) is separated from the lower surface of the closing piece 68. The mounting base 84 is moved together with the container 2 by the mounting base cylinder 86 to the contacting contact position (position shown in FIG. 6). Then, the chopper 70 and the nozzle 82 are inserted into the container 2 through the opening 20, the opening 20 is closed by the closing piece 68, and the container 2 is sandwiched and held by the closing piece 68 and the mounting base 84. .. At the contact position, the upper surface of the flange 18 of the container 2 and the lower surface of the packing 74 are in close contact with each other, so that the container 2 is sealed. Next, the rotating cage 36 is rotated by the cage motor 38 together with the container 2 about the first axis 34, and the chopper 70 is rotated by the chopper motor 80 about the second axis 72. Then, the powder P in the container 2 is mixed by rotating the container 2 together with the rotating cage 36, and as shown in FIG. 7, the inside of the upper side wall 16 which is a relatively small diameter of the container 2 is inside the container 2. Since the powder P is stirred by the stirring blade 78 of the chopper 70, the stirring efficiency can be improved. Further, an appropriate liquid may be sprayed from the nozzle 82 while the container 2 is rotating. It is preferable that the liquid is sprayed from the nozzle 82 when the closing piece 68 is positioned on the upper side (when the state shown in FIG. 6 is reached) during the rotation of the container 2. As a result, the liquid is sprayed from the nozzle 82 onto the powder P in a relatively wide range, and the injection port of the nozzle 82 is prevented from being blocked due to the powder P adhering to the nozzle 82. Even when a lump of powder P is generated by spraying the liquid, the lump of powder P is crushed by the stirring blade 78 of the chopper 70 inside the upper side wall 16 which is a relatively small diameter of the container 2. , The powder P and the liquid can be mixed with less unevenness. After the powder P is mixed by the mixer 4, the container 2 is retracted from the mixer 4 by the moving means 132. Then, when the powder P is stored in the container 2, the lid 22 is attached to the upper end of the container 2 by the lid attachment / detachment means 134.

This will be described with reference to FIG. When the powder P in the container 2 is discharged by the discharging machine 6, the holding member 116 of the discharging machine 6 moves the container 2 to the attachment / detachment position where the container 2 is attached / detached by the moving means 132. It is not necessary to remove the lid 22 from the container 2 immediately after the mixing by the mixer 4, but when the powder P in the stored container 2 is discharged by the discharger 6, the lid is first removed. The lid 22 is removed from the container 2 by means 134. Next, the swivel column 110 is appropriately swiveled by the swivel motor 118 about the vertical axis 108, and the elevating member 112 is appropriately raised and lowered by the elevating means 120 to position the holding member 116 at the holding position. Next, the container 2 is held by the holding member 116. Next, the valve 128 is moved toward the upper end of the container 2 held by the holding member 116 by the valve moving means, and the valve 128 is mounted on the upper end of the container 2. When the valve 128 with the valve body closed is attached to the upper end of the container 2, the flange 18 of the container 2 and the packing (not shown) attached to the valve 128 are in close contact with each other, so that the container 2 is in close contact with the container 2. Is sealed. Next, the swivel column 110 is appropriately swiveled around the vertical axis 108 by the swivel motor 118, and the elevating member 112 is appropriately elevated and lowered by the elevating means 120, and the container 2 is above the discharge position for discharging the powder P in the container 2. The holding member 116 is moved together with the holding member 116. Next, the holding member 116 is turned upside down by the holding member motor 126 above the discharge position together with the container 2. The container 2 may be turned upside down before being moved above the discharge position. Next, as shown by the alternate long and short dash line in FIG. 4, the elevating member 112 is lowered to the discharge position by the elevating means 120 together with the holding member 116 holding the container 2, and the lower end of the valve 128 is connected to the upper end of the discharge chute 142. .. Then, by opening the valve 128, the powder P in the container 2 is discharged to the discharge chute 142. When discharging the powder P, the discharge amount of the powder P may be controlled by adjusting the opening degree of the valve 128. When the load cell is attached to the holding member 116 or the elevating member 112, the amount of powder P discharged from the container 2 may be measured by measuring the mass of the container 2.

As described above, in the powder processing apparatus of the present invention, the rotary cage 36 is rotated by the cage motor 38 together with the container 2 while the container 2 is held by the closing piece 68 of the mixer 4 and the mounting base 84. When the chopper 70 is rotated by the chopper motor 80, the powder P in the container 2 is mixed by the rotation of the container 2, and the powder in the container 2 is mixed inside the upper side wall 16 which is a relatively small diameter of the container 2. Since P is stirred by the stirring blade 78 of the chopper 70, the stirring efficiency is improved. Further, in the powder processing apparatus of the present invention, since the opening 20 of the container 2 is single and formed at the upper end of the container 2, it is easy to secure the airtightness of the container 2 and when the container 2 is transported. The powder P does not leak from the container 2.
