A pulley that is not connected, and a pulley 11 that is coupled to the upper portion of the drive rotor 6; A belt (not shown) is wound around the pulley and the pulley 11 whose serial not shown, a base 24 for supporting the like above each portion, formed by a base 25 for fixing and supporting the base 24.
The driven rotator 7, the intermediate rotator 8, the intermediate rotator engagement / release means 9, and the position changing means 10 are installed for each of the processing containers 2, 3, 4, and 5.

The drive source 1 is, for example, a motor or the like, and the drive source 1 bears the driving force of a plurality of processing containers. The driving force of the driving source 1 is transmitted from a driving source stretching member (not shown) arranged on the upper part of the driving source 1 to a pulley 11 connected to the upper part of the driving rotating body 6 by the same rotating shaft by an endless belt (not shown). Then, the drive rotator 6 is rotated.
As the endless belt, a flat belt, a V belt, a timing belt, or the like can be used as appropriate. Further, the pulley may be changed to a sprocket to drive the chain.

The drive rotator 6 has a substantially conical shape with different diameters in the rotation axis direction of the drive rotator 6.
The driven rotator 7 has a substantially conical shape having a diameter different from that of the driven rotator 7 in the rotation axis direction, and is arranged so that the direction of the shape of the driven rotator 6 is opposite to that of the drive rotator 6.
Further, the drive rotor 6 and the driven rotor 7 having a substantially conical shape have the same gradient, and are arranged so that the gradients are parallel to each other.

  The processing containers 2, 3, 4, and 5 are containers for storing powders and processing objects and processing media therein. For example, the processing container 3 includes a container main body 3a that is rotatably supported by a support plate 12a provided with a bearing, a lid part 3b that can be moved up and down disposed on the upper part of the container main body 3a, and a container main body 3a. The guide vane 3c is supported along the inner wall at the lower part of the lid 3b.

The lid 3b can seal the container body 3a, and is supported by the elevation guide member 13 that guides the elevation movement of the lid 3b. The elevating guide member 13 can also temporarily fix the lid portion 3b at, for example, the raised position.
The guide vane 3c changes the moving direction of the workpiece 21 and the processing medium 22 that are rotated around the inner wall of the rotating processing container 3.
Although not shown, the other processing containers 2, 4, and 5 have the same configuration.

Moreover, these processing containers 2, 3, 4, and 5 are each connected to the driven rotating body 7 so as to be disassembled by reverse screws with respect to the rotation direction.
In addition, as shown in FIG. 2, the processing containers 2 and 4 represent a small thing, and the processing containers 3 and 5 represent a large thing. In addition, a processing container having a different size may be appropriately used in place of the processing containers 2, 3, 4, and 5, or an embodiment in which the number of processing containers is appropriately changed may be employed.

  The driving force transmission release means 23 is constituted by an intermediate rotator 8 that engages both between the drive rotator 6 and the driven rotator 7, and at least one intermediate rotator 8 of the drive rotator 6 and the driven rotator 7. It comprises intermediate rotor engagement release means 9 for releasing the engagement.

The intermediate rotator 8 is made of an elastic body having a high friction coefficient. When the intermediate rotator 8 is pressed against the drive rotator 6 and the driven rotator 7, the driving force is reliably transferred from the drive rotator 6 to the driven rotator 7 without slipping. And friction transmission.
The intermediate rotator 8 is preferable in that an elastic body made of a rubber-based material can absorb a shock at the time of pressing, but is not limited to this, and the driving force can be transmitted from the drive rotator 6 to the driven rotator 7. Anything is acceptable.

The intermediate rotator engagement releasing means 9 supports a first link 9a in which an intermediate rotator 8 made of an elastic body is rotatably supported at one end, and rotatably supports the other end of the first link 9a at one end. A second link 9b, a support member 9c that rotatably supports the other end of the second link 9b, and a spring 9d that connects the middle of the first link 9a and the middle of the second link 9b on the driven rotor 7 side. And an air cylinder 9e that has one end rotatably supporting the middle of the second link 9b, the other end rotatably supported by the support member 9c, and pushes the second link 9b by air pressure. The air cylinder 9e is configured to be contracted to a predetermined position by a spring provided therein when no air pressure is applied.
With the above configuration, the intermediate rotator 8 made of an elastic body can be pressed against or released from the drive rotator 6 and the driven rotator 7.

The position changing means 10 has bushes 10a provided at three ends of the support member 9c, and passes through the bush 10a. One end is supported by the support plate 12b and the other end is supported by the support plate 12c perpendicularly to the ground. A guide shaft 10b for guiding the support member 9c, a lift ball screw 10c for moving the support member 9c up and down along the guide shaft 10b, and a worm gear 10d for rotating the lift ball screw 10c are provided.
With the configuration described above, the intermediate rotor engagement / release means 9 can be moved and held in the direction of the rotation axis of the drive rotor 6.

Next, the operation of the powder processing apparatus A will be described.
First, the processing object and the processing medium are accommodated in the processing containers 2, 3, 4, and 5. Next, the drive source 1 is rotationally driven to rotate the pulley 11 via a belt (not shown). Since the pulley 11 and the drive rotator 6 are connected by the same rotation shaft, the drive rotator 6 rotates.
Before the intermediate rotor 8 is pressed, the first link 9 a and the second link 9 b are pulled by the spring 9 d, and the intermediate rotor 8 is pressed only against the driven rotor 7. At this time, each part of the drive means is arranged so that the intermediate rotator 8 does not contact the drive rotator 6.
In order to press the intermediate rotating body 8, air is supplied into the air cylinder 9e, and the second link 9b is pressed by the thrust generated by the pressure. Then, the intermediate rotating body 8 is pressed against the driven rotating body 6 while being pressed against the driven rotating body 7 by the spring 9d. Then, friction drive transmission is performed from the drive rotator 6 to the driven rotator 7. As a result, the processing containers 2, 3, 4, and 5 connected to the driven rotating body 7 are rotated. The spring 9d also has a function of absorbing contact position deviation of the intermediate rotator 8 with the drive rotator 6 and the driven rotator 7 that occur in association with a shift described later.
As a result, in the processing containers 2, 3, 4, and 5, the workpiece and the processing medium are swung to the inner walls of the processing containers by centrifugal force, and scraped by the guide vanes that are fixed to the lids that do not rotate. The direction of motion is changed. The to-be-processed object and the processing medium that have been turned are subjected to powder processing, for example, by colliding with the inner wall of the processing container. FIG. 6 shows a state of powder processing in the rotating processing container 3. The same applies to the other processing containers 2, 4, and 5.
In addition, if each processing container with a different diameter is installed, powder processing under different conditions can be performed.

In order to stop the rotation of the processing container, the air supply to the air cylinder 9e is stopped, the air cylinder 9e is contracted by a spring provided inside the air cylinder 9e, and the second link 9b is pulled to the drive rotating body 6. What is necessary is just to release the pressing of the intermediate rotating body 8. At this time, a natural stop is made, but for safety, an electromagnetic brake may be provided in the vicinity of the driven rotor 7 and stopped.
In the intermediate rotator engagement / release means 9, the intermediate rotator 8 is always in contact with the driven rotator 7, but the intermediate rotator 8 is always in contact with only the drive rotator 6, It is good also as a drive means pressed against the driven rotator 7 only when driving is transmitted. Alternatively, the intermediate rotator 8 may be put on standby in a state where it is separated from both the drive rotator 6 and the driven rotator 7, and drive means that presses the intermediate rotator 8 only when it is driven.

Next, in order to change the rotation speed of the processing container, the pressing position of the intermediate rotator 8 is changed by the position changing means 10 along the gradients of the shapes of the drive rotator 6 and the driven rotator 7. This principle is shown below.
FIG. 4A shows a case where the intermediate rotator 8 is pressed in the upper part in the axial direction between the drive rotator 6 and the driven rotator 7, and FIG. FIG. 4C is a diagram showing a case where the driving rotary body 6 and the driven rotary body 7 are pressed at the central portion in the axial direction. FIG. 4C shows the intermediate rotary body 8 between the drive rotary body 6 and the driven rotary body 7. It is a figure which shows the case where it is pressed by the lower part between.
In the case of FIG. 4A, the diameter of the drive rotator 6 is larger and the diameter of the driven rotator 7 is smaller than in the case of FIG. 4B. If the speeds of the drive rotators 6 in FIGS. 4 (a) and 4 (b) are the same, the speed of the contact portion of the drive rotator 6 with the intermediate rotator 8 is higher in FIG. 4 (a). Since it is fast, the rotation of the intermediate rotator 8 is faster in FIG. 4 (a) has a smaller diameter than that of FIG. 4 (b), so if the speed of the intermediate rotating body 8 is the same in FIGS. 4 (a) and 4 (b), The driven rotor 7 of 4 (a) rotates faster. Therefore, in the case of FIG. 4A, the above two effects are overlapped, and the driven rotating body 7 is rotated faster than in the case of FIG. 4B. Therefore, in the case of FIG. 4A, the processing container 1 can be rotated faster than in the case of FIG.
On the other hand, in the case of FIG. 4C, the diameter of the drive rotator 6 is smaller and the diameter of the driven rotator 7 is larger than in the case of FIG. 4B. Since it can be considered in the same manner as the comparison of FIGS. 4A and 4B, the processing container 1 can be rotated more slowly in the case of FIG. 4C than in the case of FIG. 4B.
Therefore, if the position of the intermediate rotating body engagement / release means 9 is changed as appropriate by the position changing means 10 and the intermediate rotating body 8 is pressed by the intermediate rotating body engagement / release means 9 to transmit friction, the rotational speed of the processing container is reduced. can do. As a result, powder processing under various conditions becomes possible.

  Further, since the intermediate rotor engagement releasing means 9 and the position changing means 10 are provided in each of the processing containers 2, 3, 4, and 5, each processing container is driven or stopped independently, or the rotation speed is increased. Can be shifted.

  According to the present embodiment, the clutch operation between the drive source 1 and the processing containers 2, 3, 4, 5 can be performed, and the driving force can be transmitted to the processing containers 2, 3, 4, 5, You can cancel it. Therefore, since each processing container is independent, it is not necessary to balance between each processing container, and even when the mass of each processing container differs, it can be rotated stably.

  Furthermore, the position where the intermediate rotator 8 is pressed can be changed, and the diameters of the drive rotator 6 and the driven rotator 7 against which the intermediate rotator 8 is pressed change depending on the position. it can. That is, powder processing under various conditions can be performed in each processing container.

  In addition, the drive force can be transmitted even if the drive source is arranged at a position separated from the drive rotator, so that the space can be effectively utilized while considering the positional relationship with the processing container, and the apparatus can be downsized. Can do.

  Next, a modification of the above embodiment will be described. For example, instead of the driving force transmission releasing means 23, transmission of driving force between the driving rotating shaft 6 and the driven rotating shaft 7 can be performed by a winding transmission device (pulley and V belt method, toothed pulley and timing belt method, A clutch (for example, an electromagnetic clutch (including a magnetic fluid clutch)) that transmits and releases driving force is provided between each driven rotor 6 and each processing container. It may be a thing.

  In order to transmit and release the driving force, a clutch similar to that of the above-described modified example is provided, and the shape of the driving rotator 6 and the shape of the driven rotator 7 are the same as those of the above-described embodiment for shifting the processing containers. And the position changing means 10 may change the position of the intermediate rotating body 8. In this case, the drive force transmission release means only needs to have a mechanism for pressing the intermediate rotator 8, and does not necessarily require a mechanism for releasing the intermediate rotator 8 from the drive rotator 6 or the driven rotator 7.

Next, another embodiment of the present invention will be described. FIG. 5 is a schematic view of another embodiment of the powder processing apparatus according to the present invention.

The continuously variable transmission 15 corresponding to 10 is further provided. The continuously variable transmission 15 changes the belt winding position in the radial direction by changing the width of the groove of the driving rotating body stretching member on which the V-belt is hung.

In order to prevent the V belt 19 from sagging when the continuously variable transmission 15 is operated, an idler pressed against the V belt 19 is provided as the sagging prevention member 20.
The dotted lines in FIG. 5 indicate the track of the V belt 19, the diameter of the pulley 15a of the continuously variable transmission 15 through which the V belt 19 passes, and the sagging prevention member when the continuously variable transmission 15 is shifted and rotated at high speed. 20 shows a state in which the V-belt 19 is prevented from sagging and is in tension.

  According to the powder processing apparatus B of this embodiment, the driving force of the inverter motor 16 that is a driving source can be transmitted to the pulleys 15a, 17, and 18 by friction as in the above-described embodiment. Further, when performing a shift by the continuously variable transmission 15, it is not necessary to change the position in the direction of the rotation axis of the processing container unlike the position changing means 10 of the above embodiment, so that the height of the apparatus can be suppressed. While being simple and compact, it is possible to provide a powder processing apparatus having the same effect as the above embodiment.

  Further, in the powder processing apparatus B of the present embodiment, a geared transmission may be used instead of the continuously variable transmission 15. Furthermore, in the powder processing apparatus B of the present embodiment, the continuously variable transmission 15 is used only for one processing container, but may be provided for each of a plurality of processing containers.
