  The processed product receiver 8 is integrated with the end of the discharge feeder 7 on the inside of the processing container 2. The processed product receiver 8 receives the processed material and the processing medium guided by the guide plate 9 and supplies them to the discharge feeder 7.

  The guide plate 9 is a plate-like member, and a long side thick portion of the guide plate 9 is arranged such that one end is disposed at the upper portion of the receiving port of the processing object receptacle 8 and the other end is disposed at the lower portion of the guide vane 3 on the discharge port 5 side. Is attached to the side beam 15 so that

  The driving pulley 10 is transmitted with a driving force from a motor (not shown) via a V belt and the like, and further transmits the driving force to the processing container 2.

  The guide vane support shafts 11 and 12 are cylindrical members having through holes, and are fixed so as to be integrated with the side flanges 18 and 17, respectively. At this time, the diameters of the holes formed in the side flanges 18 and 17 and the diameters of the through holes of the guide vane support shafts 11 and 12 are the same, and are fixed so that the circles of these sections overlap. It is.

  The bearings 13 and 14 are ring-shaped members whose centers are arranged on the rotation axis of the processing container 2 so as to rotatably support the shaft portion 2a of the processing container 2 therebetween.

At this time, since the side beam 16 is fixed, when the torque arm 19 is rotated around the rotation axis of the processing vessel 2, the side beam 15 together with the side flange 17 and the guide vane support shaft 12 is rotated around the rotation axis of the processing vessel 2. And a phase difference is generated with respect to the side beam 16. As a result, the guide vane 3 can be tilted.

  In addition, it becomes easy to make the inside of the processing container 2 into sealed space by integrating as mentioned above. For example, sealing (not shown) is performed on one of the outer diameter portions of the cylinder 7a of the discharge feeder 7, and the sealing function is maintained with the processing object and the processing medium inlet and the processing object and the processing medium discharge port kept sealed. If the bearings 13 and 14 having the above are used, the inside of the processing container 2 can be completely sealed.

Next, the operation of the powder processing apparatus 1 according to this embodiment will be described.
First, while the motor 6e of the supply feeder 6 is being operated, is inserted into the insertion port 6b. Then, the object to be processed and the processing medium are sequentially transferred from the cylinder 6a at the bottom of the charging port 6b to the processing container 2 side by the shaft 6c and the spiral member 6d driven by the motor 6e, and the supply port 4 side inside the processing container 2 Dropped to the bottom.

  Next, the processing container 2 is rotated by a motor (not shown) via a V belt (not shown). However, this rotation may be performed before the workpiece and the processing medium are supplied into the processing container 2. By the rotation of the processing container 2, the object to be processed and the processing medium are taken along the inner wall of the processing container 2 and scraped off by the guide vane 3 from the inner wall of the processing container 2. At that time, the end of the working surface of the guide vane 3 on the inner wall side of the processing container 2 is inclined in the rotation direction of the processing container 2 from the supply port 4 side to the discharge port 5 side with respect to the rotation axis of the processing container 2. As shown by the dotted arrows in FIG. 1, the object to be processed and the processing medium scraped by the guide vanes 3 are changed in their moving directions and are sent so as to gradually approach the discharge port 5 side. As shown by the dotted arrow in FIG. 2, the change of the moving direction is repeated while performing the powder processing. Here, FIG. 3 shows a state of powder processing near the center of the guide vane 3 in the rotation axis direction. A part of the processing object 22 and the processing medium 23 that are accompanied by the rotation of the processing container 2 are separated from the inner wall of the processing container 2 by the guide vane 3 to change the direction of movement, and the layer of the processing object 22 The powder processing is performed by colliding with.

  Finally, as shown by the thick arrows in FIGS. 1 and 2, the processed material and the processing medium are disposed near the discharge port 5 by the guide plate 9 while the processing container 2 is rotated. It is guided to the receptacle of the receptacle 8 and dropped. The processed material and the processing medium dropped on the processed material receiver 8 are conveyed to the upper portion of the discharge port 7b by the shaft 7c and the spiral member 7d driven by the motor 7e of the discharge feeder 7, and then discharged from the discharge port 7b. The

  Therefore, since the inputted processing object and the processing medium are sequentially discharged, if the processing object and the processing medium are sequentially input to the input port 6b by a predetermined amount, the powder processing apparatus 1 continues the above operation. Can be done.

  According to the present embodiment, the supplied object to be processed and the processing medium and the processing object that are rotated around the inner wall of the processing container 2 are turned in the direction in which the guide vane 3 is inclined. Can send. In addition, since the processed material sent can be sequentially discharged from the discharge port 7b, the next material to be processed supplied from the supply port 4 can be processed continuously while the processing container 2 is rotated.

  In addition, the processing object 2 can be reliably supplied and the processing object can be discharged without stopping the rotation of the processing container 2.

  As shown in FIG. 1, the processing time of the workpiece can be set by turning the torque arm 19 and adjusting the inclination θ of the guide vane 3. Specifically, in FIG. 1, if the inclination θ of the guide vane 3 is increased, the turning angle becomes larger, and the speed of feeding from the supply port 4 side to the processing object and the processing medium or processing object to the discharge port 5 side is increased. If the inclination θ of the guide vane 3 is reduced, the turning angle becomes smaller, and the speed of feeding the workpiece and the processing medium and the workpiece from the supply port 4 side to the discharge port 5 side becomes slower. Therefore, by adjusting the inclination θ of the guide vane 3, it is possible to set the time (processing time) for sending the workpiece from the supply port 4 to the discharge port 5. In other words, the feed movement amount of the workpiece and the processing medium in one powder processing can be arbitrarily adjusted.

  Although not shown, only the processed object is excluded by removing the processing medium (for example, a medium ball) by covering the receiving part of the processing object receiver 8 with a mesh member or making the receiving part smaller than the processing medium. It is good also as a structure which has a guide member which rolls back the processing medium excluded from the processed material receptacle 8 to the supply port 4 side and center of the processing container 2 in FIG. The same applies to the following modifications and embodiments.

  Next, a second embodiment will be described. In addition, description may be abbreviate | omitted about the location similar to the said embodiment. FIG. 4 is a sectional view in the direction of the rotation axis of the processing container 25 of the powder processing apparatus according to the second embodiment. In the powder processing apparatus according to the second embodiment (not shown), a guide vane 24 and a side beam 42 for supporting the guide vane 24 are further provided inside the processing container 2 of the powder processing apparatus 1 according to the first embodiment. It is what has been.

  As shown in FIG. 4, the guide vane 24 has an inner wall of the processing container 25 and a processing medium so that the workpiece and the processing object can pass along the inner wall of the processing container 25 before the rotation direction of the guide vane 3. It is arranged with a gap smaller than the size of. Further, the working medium has a working surface that separates the processing medium from the processing container 25 and changes the direction of movement of the processing medium, and the end of the working surface on the inner wall side of the processing container 25 is provided in parallel with the rotation axis direction of the processing container 25. It has been.

  The side beam 42 is a substantially L-shaped plate member. One end is rotatably connected between the outer diameter of the side flange 18 on the supply port side and the outer diameter of these holes, and the other end supports one end of the guide vane 24. Although not shown, a similar side beam is also provided on the discharge port side, and supports the other end of the guide vane 24.

  Next, the operation of the powder processing apparatus according to the second embodiment will be described. Since the operation is the same as that of the first embodiment except for the operation inside the processing container 25, the operation inside the processing container 25 will be omitted. I will explain only. FIG. 5 shows a state of powder processing inside the processing container of the powder processing apparatus according to the second embodiment.

  Due to the rotation of the processing container 25, the workpiece 22 and the processing medium 23 are rotated along the inner wall of the processing container 25. First, a small amount of the processing object 22 and the processing medium 23 are scraped off from the inner wall of the processing container 2 to the guide vane 24. Then, the movement direction of the object to be processed 22 and the processing medium 23 is changed as indicated by the one-dot chain line arrow shown in FIG. 4 and collides with the other object to be processed 22 on the inner wall of the processing container 2 to process the powder. I do. Note that due to the characteristics of the guide vane 24, the processing medium 23 does not have a feeding action toward the discharge port 5.

  The workpiece 22 that has passed through the gap between the guide vane 24 and the inner wall of the processing container 25 is scraped off from the inner wall of the processing container 2 by the guide vane 3. At that time, the end of the working surface of the guide vane 3 on the inner wall side of the processing container 2 is inclined in the rotation direction of the processing container 2 from the supply port 4 side to the discharge port 5 side with respect to the rotation axis of the processing container 2. The workpiece 22 scraped off by the guide vanes 3 is changed its direction of movement and is sent so as to approach the outlet 5 side little by little. As shown by the dotted arrow in FIG. 4, the movement direction is repeated while the powder is being processed. Here, FIG. 5 shows a state of powder processing near the center of the guide vane 3 in the rotation axis direction. The guide vane 24 separates a small amount of the processing object 22 and the processing medium 23 that accompany the rotation of the processing container 2 from the inner wall of the processing container 2 and changes the direction of movement thereof, thereby forming a layer of the processing object 22. Powder processing is performed by making it collide. At this time, if the guide vane 24 is adjusted so as to collide with the workpiece 22 sent by the change in the direction of movement by the guide vane 3 and the feeding action toward the discharge port 5, high efficiency of powder processing can be achieved. Can be achieved.

  Finally, as shown by the thick arrow in FIG. 4, while the processing container 2 is rotated, the processed product and the processing medium are placed in the vicinity of the discharge receptacle 5 by the guide plate 9 in the vicinity of the discharge port 5. It is guided to the receiving port one by one and dropped.

  Therefore, since the inputted processing object and the processing medium are sequentially discharged, if the processing object and the processing medium are sequentially input into the input port by a predetermined amount, the powder processing apparatus 26 continuously performs the above operation. It can be carried out.

  According to the second embodiment, the same effects as those of the first embodiment can be obtained, and the processing medium can be kept in the processing container as it is and the powder processing can be continued. Therefore, once the processing medium is accommodated in the processing container 25, it is sufficient to supply only the object to be processed, and only the processing object needs to be discharged. When the processing medium is discharged, it is necessary to separate the processing object and the processing medium. There will be no.

  Next, the powder processing apparatus 26 according to the third embodiment will be described. In addition, description may be abbreviate | omitted about the same location as said each embodiment. 6A and 6B are diagrams showing a powder processing apparatus 26 according to a modification of the powder processing apparatus 1 according to the first embodiment, in which FIG. 6A is a schematic diagram of a main part of the powder processing apparatus 26, and FIG. It is (b)-(b) sectional view of (a).

  The powder processing apparatus 26 is different from the powder processing apparatus 1 in that the discharge port 27 is provided in the vicinity of the circumference of the end surface of the processing container 28. Moreover, it differs also in the point which becomes the structure which can discharge | emit the processed material and processing medium discharged | emitted from the discharge port 27 inside the stationary outer peripheral container 29, and can take out in a sealed state.

  As shown in FIG. 6B, the processing container 28 is provided with four discharge ports 27 in the vicinity of the circumference of the end surface. The discharge port 27 is an elliptical hole with a long cross section.

  The outer peripheral container 29 is disposed so as to cover the outside of the discharge port 27 and the periphery of the processing container 28 on the discharge port 27 side. The processed material and the processing medium discharged from the processing container 28 are discharged outside in a sealed state. Further, the processing vessel 28 is rotatably supported via the bearing 34.

  The guide vane support shaft 30 is a rod-like member disposed on the rotation axis of the processing vessel 28 and fixedly supports the side beam 32. Further, the bearing 33 is also supported rotatably.

  The side beam 32 fixes and supports the guide vane 31. Although not shown, the guide vane 31 is supported at both ends by the other side beam and the side beam 32.

  Next, the operation of the powder processing apparatus 26 will be described. The object to be processed and the processing medium supplied in the same manner as in the first embodiment are rotated around the inner wall of the processing container 28, and the direction of movement is changed to perform powder processing. While the object to be processed and the processing medium are subjected to powder processing, the object to be processed and the processing medium supplied next are gradually washed away from the supply port side to the discharge port 27 side. Finally, it overflows from the discharge port 27 and is discharged to the outer peripheral container 29. And it is discharged | emitted from the outer peripheral container 29 lower part outside.

  Therefore, since the inputted processing object and the processing medium are sequentially discharged, if the processing object and the processing medium are sequentially input into the input port by a predetermined amount, the powder processing apparatus 26 continuously performs the above operation. It can be carried out.

  Next, a modified example of the mechanism for tilting the guide vane 3 of the first and second embodiments will be described. FIG. 7 is a view showing a modification of the mechanism for inclining the guide vane 3 of the first embodiment and the second embodiment, where (a) is a front sectional view, and (b) is a side beam of (a). It is an end sectional view of the direction of a rotation axis.

  In this modification, a guide vane 35 is used instead of the guide vane 3 of the first and second embodiments. Further, side beams 36 and 37 are used instead of the side beams 15 and 16.

  A spherical body 38 is connected to the guide vane 35 via a connecting portion 39 on the supply port side, and slides in the length direction of the guide vane 35 in a space 36a provided in the side beam 36 on the discharge port side. A free sliding member 41 is connected via a connecting portion 40.

  The side beam 36 has a space 36a inside, and is rotatable about the rotation axis direction of the processing container (in the direction of the arrow shown in FIG. 7B) similar to the first and second embodiments. It is. The space 36a is provided with an opening 36b on the supply port side so that the connecting portion 40 can move in the direction of the rotation axis of the processing container (not shown). The space 36a also serves to prevent the sliding member 41 from rotating.

  The side beam 37 is fixedly supported on the side flange 18 similar to the first and second embodiments. Further, a spherical bearing 37a into which a spherical body 38 is press-fitted is provided so that the guide vane 35 can swing.

  The shape of the sliding member 41 is such that the surface on one side and the other end connected to the connecting portion 40 which is a semicircular plane, the same opposite surface, and the peripheral portions of these planes are connected. The cross section is formed from a semicircular curved surface. The sliding member 41 supports the space 36a so as to be slidable in the length direction of the guide vane 35 and to prevent the guide vane from rotating.

Next, the operation of the above modification will be described.
Except for the guide vane 35 and the side beams 36 and 37, the second embodiment is the same as the first and second embodiments. Here, in the first embodiment shown in FIG. 1, the guide vane 3 and the side beams 15 and 16 are replaced with the guide vane 35 and the side beams 36 and 37.

  The side beam 37, the side flange 18, the guide vane support shaft 11, and the cylinder 6a are integrated and fixed. On the other hand, the side beam 36, the side flange 17, the guide vane support shaft 12, and the torque arm 19 are also integrated, and this integrated portion is rotatably supported by the cylinder 7a. At this time, the side beam 37 has a spherical bearing 37a into which the spherical body 38 is press-fitted so that the guide vane 35 can swing, so that the torque arm 19 is rotated around the rotation axis of the processing container 2. Then, the side beam 36 together with the side flange 17 and the guide vane support shaft 12 rotates around the rotation axis of the processing container 2, and a phase difference is generated with respect to the side beam 37. As a result, the guide vane 35 supported at both ends by the side beams 36 and 37 can be tilted.

  According to the modified example, the phase difference corresponding to the inclination θ of the guide vane 35 can be generated by rotating the same guide vane support shaft 12 as in the first and second embodiments. By arbitrarily adjusting the rotation of the guide vane support shaft 12, the inclination θ of the guide vane 35 is changed, and the feed movement amount of the workpiece and the processing medium in one powder processing can be arbitrarily adjusted.

  In addition, it is good also as sending a to-be-processed object etc. to the discharge port side according to the shape of guide vane itself, as shown in FIG. 8, without giving the phase difference of a side beam like the said modification.

  The guide vane 43 shown in FIG. 8A has a substantially triangular cross section, and the working surface is a concave curved surface. 8B is a view of FIG. 8A viewed from the right hand side of the drawing, and FIG. 8C is a view of FIG. 8A viewed from the left side of the drawing surface.

  As shown in FIGS. 8 (b) and 8 (c), the lower part of the shaft 44 for connecting the concave curved surface, which is the working surface of the guide vane 43, to the side beam as it proceeds from the right hand to the left hand of FIG. 8 (a). The shape gradually becomes a gentle gradient with respect to the side. Further, as shown in FIG. 8A, the end portion 43a of the guide vane 43 on the inner side of the processing vessel is aligned with the gap between the end portion 43a of the guide vane 43 on the inner side of the processing vessel and the inner wall of the processing vessel (not shown). It has a shape.

  Thereby, it is possible to generate a feeding action of the object to be processed without tilting the guide vanes.

  Although not shown in the figure, the concave curved surface, which is the working surface of the guide vane 43, may be gradually increased with respect to the side below the shaft 44 for connecting to the side beam, or may be the same gradient. The concave curved surface that is the working surface of the guide vane 43 may be a flat surface.

  Further, in FIG. 8A, the end portion 43a of the guide vane 43 on the inner side of the processing vessel is shaped so as to match the gap between the end portion 43a of the guide vane 43 on the inner side of the processing vessel and the inner wall of the processing vessel not shown. However, it is also possible to generate a feeding action of the object to be processed, etc., by forming the end on the opposite side into a substantially arc shape (not shown) matching the gap with the inner wall of the processing container. In this case, the end 43a may be horizontal in the direction of the axis 44.

  Next, the shape correction of the end portion of the guide vane on the inner side of the processing container with respect to the change in the gap between the guide vane and the inner surface of the processing vessel when the inclination θ of the end portion on the inner side of the processing vessel of the guide vane is changed will be described. .

  When the inclination θ of the end portion of the guide vane on the inner side of the processing container is small, as described above, the end portion of the guide vane on the inner side of the processing container is separated from the end portion of the guide vane on the inner side of the processing vessel and the inner wall of the processing vessel. It is possible to cope with it by making the shape according to the gap. However, when the inclination θ of the end portion of the guide vane on the inner wall side of the processing container is large, the gap becomes large, and thus a small amount of the workpiece whose direction of movement is not changed remains in the central portion of the processing container. For this reason, it is necessary to correct the shape of the end portion of the guide vane on the inner wall side of the processing container.

  For example, as the shape correction, as shown in FIG. 9B, a guide vane 46 that is divided into three parts can be cited. The guide vane 46 includes a central portion 46 a and sliding members 46 b and 46 c that are slidable in the width direction of the guide vane 46. This sliding is achieved by an eccentric bush structure or a sliding mechanism (not shown).

  As a result, even when the inclination θ of the end portion on the inner wall side of the guide vane is large, the gap between the end portion on the inner wall side of the guide vane and the inner wall of the processing vessel is eliminated, and the motion of almost all the workpieces The direction can be changed.

  Although not shown, each guide vane may have a divided structure composed of at least two segments (portions). For example, an integrated guide vane is divided into a plurality of pieces in the longitudinal direction, and each segment has a shape similar to the divided shape. The rod-shaped central axis is passed through the central part of each segment, each segment is locked to the central axis of the rod with a key or a spline, and the segments are appropriately joined together so as to function as a guide vane. By adopting such a configuration, processing in units of segments is possible, so that a guide vane having a working surface having a target inclination can be reliably and easily manufactured.
