Description

The present invention relates to a container for a crusher suitable for, for example, crushing and crushing tablets, and a crusher equipped with the same.

Currently, tablets are generally large in size for adults, and are also large in size for children. For this reason, for children and people who have difficulty swallowing, the drug is crushed in hospital drug rooms, pharmacies, etc. to make it into a size that can be swallowed and dispensed in appropriate amounts.
In addition, capsules are similarly sized and contained for adults, so ``decapsulation'' is performed to remove the capsule and extract the contents.
In addition to the method of crushing objects such as tablets using a mill with rotating blades, for example, the object to be processed is placed in a container and the container is rotated and revolved to stir and crush the object. The use of a device that does this is being considered.
Effective equipment for decapsulation is not widely available, and pharmacists manually remove capsules and extract the contents.

Conventionally, for example, Patent Document 1 discloses that a material to be processed (stirred material) is stored in a bottomed cylindrical stirring container, and balls such as zirconia balls for assisting in pulverization are further placed in the stirring container. A rotary stirring device is described in which a stirring container is rotated and revolved while it is placed together with an object. That is, a method is described in which pulverization is performed using a ball mill using an autorotation-revolution stirring method.
Furthermore, a technique of decapsulation using a rotation-revolution mixer is proposed in Patent Document 2.

Patent No. 5984130 Utility model registration No. 3236641

In the above conventional techniques, the following problems remain.
In other words, when grinding is carried out using the rotation-revolution agitation method, a method has been proposed in which balls are inserted to assist the grinding to create a ball mill, but this requires removing the balls from the powder after grinding, which makes the work more difficult. In addition to being time-consuming, there is also the problem of contamination due to mixed balls. In addition, it was difficult to set conditions such as the number and size of balls to be added, making it difficult to obtain a good pulverized product.
Furthermore, in the case of capsules, it was not possible to remove the contents by simply scraping the surface of the capsule with a ball.

The present invention was made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a container for a crusher that can perform good crushing, crushing, and decapsulation without using balls, and a crusher equipped with the same. do.

The present invention employs the following configuration to solve the above problems. That is, the container for a crusher according to the first invention includes: a revolving body that is rotatable around an axis of revolution; a rotating body that is held by the revolving body and rotatable around an axis of rotation; A container for use in a pulverizer that performs pulverization without using balls, the container having a drive mechanism for rotationally driving a rotating body, the container being attached to the rotating body, having an axis set to be the same as the rotation axis, and having an opening at the top. a cylindrical container body with a bottom, a lid member for the main body capable of closing the opening of the cylindrical container body, and a lid member for the main body that is provided at or can be stored in the lower part of the cylindrical container body and has an open top. a collection container part; a crushing container part installed above the collection container part in the cylindrical container main body and capable of storing the object to be processed and having a through hole formed in the bottom; A sieve member is provided between the recovery container section and the crushing container section in the container body, and has a finer sieve mesh than the particle size of the object to be processed stored in the crushing container section. It is characterized by

In this crusher container, a sieve member is installed between the recovery container and the crushing container in the cylindrical container main body, and has a finer sieve mesh than the particle size of the material to be processed stored in the crusher. Since the powder is scraped in the crushing container by rotation and revolution, the powder of the powder (or decapsulated powder) that has been crushed and finely falls down from the through hole, and the powder that has become finer than the mesh of the sieve is removed. Only the powder particles fall from the sieve member into the collection container. By adopting this two-layer system consisting of the crushing container section and the recovery container section with the sieve member sandwiched between them, the fine powder of the processed material, which acts as a buffer in the crushing container section, passes through the sieve member to a separate room. By falling into the collection container, being moved, and separated, it does not interfere with the pulverization within the pulverization container, allowing efficient pulverization and improving the pulverization rate.
In other words, by adopting a two-chamber structure, it is possible to separate the pulverized material (powder of the processed material) during pulverization investigation, avoid a drop in pulverization efficiency, and reach the pulverization end point (all powders) in a single pulverization operation. It becomes possible to reach the point where the processed material (raw material) has a particle size below the desired size.
In addition, since the pulverization does not proceed in the collection container, and the sieve member acts as a separation wall and the frequency of the pulverized material moving to the pulverization container is low, over-pulverization of the pulverized material can be prevented. Decrease in fluidity of the product can be avoided.
Furthermore, since the sieve mesh of the sieve member scrapes the material to be processed during rotation, finer powder of the material to be processed can be obtained. In particular, as the material to be processed rolls on the surface of the sieve mesh of the sieve member, the powder of the material to be processed scraped by the sieve member tends to form a high-quality spherical shape.
In addition, in Patent Document 2, a sieve is attached to the top surface of the container in order to take out the powder after the work, but unlike the present invention, the sieve is not built into the container during crushing. It is not possible to remove powder, which cushions the impact and reduces grinding efficiency.

A container for a crushing device according to a second aspect of the invention is provided with a cylindrical crushing-side buffer member that covers the outer periphery of the crushing container part made of a material that is softer than the crushing container part in the first invention. It is characterized by
In other words, this crusher container is equipped with a cylindrical crushing side buffer member that covers the outer periphery of the crushing container using a material that is more flexible than the crushing container, so that the radial direction of the crushing container is prevented during rotation. By alleviating vibrations by the crushing side buffer member, deformation of the crushing container portion can be prevented.

A container for a crusher according to a third aspect of the invention is provided with a cylindrical collection-side buffer member that covers the outer periphery of the collection container part using a material that is more flexible than the collection container part in the first invention. It is characterized by
In other words, this crusher container is equipped with a cylindrical collection-side buffer member that covers the outer periphery of the collection container using a material that is more flexible than the collection container, so that the axial direction of the collection container is prevented during rotation. By alleviating vibrations by the collection-side buffer member, deformation of the collection container section can be prevented.

A container for a crushing device according to a fourth aspect of the present invention, in the first aspect, includes a crushing plate section provided in the crushing container section and having a blade section extending along the axis of the crushing container section. It is characterized by the presence of
In other words, this container for a crushing device includes a crushing plate section that is provided in the crushing container section and has a blade section that extends along the axis of the crushing container section, so that the object to be processed is not crushed during rotation. It is crushed by colliding with the plate part, and the crushing effect is further improved.

A container for a crushing device according to a fifth aspect of the invention is characterized in that, in the first aspect, the sieve member has a plurality of uneven parts for scraping formed on the surface on the side of the crushing container part. .
That is, in this container for a crusher, the sieve member has a plurality of uneven parts for scraping formed on the surface on the side of the crushing container, so that when rotating, the object to be processed is processed by the uneven parts for scraping, like grated radish. The grinding effect is further improved by grinding.

A container for a pulverizer according to a sixth aspect of the present invention is characterized in that, in the first aspect, the sieve member has a plurality of sieve holes formed in a metal plate to serve as the sieve openings.
That is, in this container for a crusher, the sieve member is a metal plate with a plurality of sieve holes formed as sieve meshes, so it is possible to obtain the same effect as a mesh-like sieve member, and also Sieve holes can be easily formed in the area. Furthermore, by changing the pore diameter, pore area, arrangement, etc. of the sieve holes, it is possible to control the particle size, separation efficiency, etc. Furthermore, the sieve holes drilled in the metal plate by hole punching have sharper edges than the mesh sieve portion, and a higher shaving effect can be obtained.

In the container for a pulverizer according to a seventh invention, in the sixth invention, the sieve member has a central region where the sieve holes are not formed and a plurality of the sieve holes are formed on the outer periphery of the central region. It is characterized by having a sieve area.
That is, in this container for a crusher, the sieve member has a central region in which no sieve holes are formed and a sieve region in which a plurality of sieve holes are formed on the outer periphery of the central region. It is possible to drop the powder downward from the outer sieve area and separate it, and to prevent the powder from flowing back from the central area and returning into the crushing container.
For example, when pulverization is performed by rotating and revolving at a high rotation angle, a vertical convection occurs in the pulverizing container in which the material to be processed rises at the center where the axis is located and descends at the outer periphery. Therefore, by forming the sieve area only on the outer periphery, the crushed powder is effectively dropped from the outer periphery, and the central area without sieve holes prevents the powder from returning from the center to the crushing container. can.

A pulverizer according to an eighth aspect of the present invention includes a revolving body that is rotatable around an axis of revolution, a rotating body that is held by the revolving body and rotatable around an axis of rotation, and the revolving body and the rotating body. The present invention is characterized in that it includes a rotationally driven drive mechanism and a container for a crusher according to any one of the first to seventh aspects of the invention, and performs crushing without using balls.

In the crushing device according to a ninth invention, in the eighth invention, the drive mechanism rotates the revolution body at a relatively high rotation speed for crushing, and then rotates the revolution body at a relatively high rotation speed for crushing. The invention is characterized in that a two-step rotation is repeatedly performed in which the revolution body is rotated at a collection rotation speed where the revolution speed of the revolution body is relatively lower than the number of revolutions.
In this crushing device, the drive mechanism rotates the revolution body at a rotation speed for crushing, where the rotation speed of the revolution body is relatively high, and then rotates the revolution body at a rotation speed for recovery, where the rotation speed of the revolution body is relatively lower than the rotation speed for crushing. Since the two-stage rotation of rotating the revolution body at the rotational speed is repeated, the powder is removed by rotating at a high rotational speed for crushing and the powder is removed by rotating at a slow rotational speed for collection. Can be re-ground.
In other words, after the material to be processed is pulverized by the strong centrifugal force generated by rotation at a high rotational speed for pulverization, the centrifugal force is weakened by rotation at a slow rotational speed for collection, and the effect of raising the material to be processed is weakened. The powder of the processed material can be moved to the collection container section through the sieve member and removed from the pulverization container section. Then, by rotating again at a high pulverization speed, the material to be processed can be pulverized again in the pulverization container with the powder that would act as a buffer material removed, resulting in efficient pulverization. becomes possible.

According to the present invention, the following effects are achieved.
That is, according to the container for a crushing device and the crushing device equipped with the same of the present invention, the container that is installed between the collection container section and the crushing container section in the cylindrical container main body and stored in the crushing container section. Since it is equipped with a sieve member whose sieve mesh is finer than the particle size of the material to be processed, the fine powder of the material to be processed, which acts as a buffer in the crushing container section, falls through the sieve member into the collection container section in a separate room. By being moved and separated, the particles do not interfere with the pulverization within the pulverization container, allowing efficient pulverization and improving the pulverization rate.
Therefore, the container for a crusher and the crusher of the present invention can efficiently crush the object to be processed without using balls or the like, and are suitable for crushing tablets and the like.

Further, the crushing container section 7 includes a crushing lid section 7b that can close the upper opening.
Note that the object to be processed is, for example, a solid object such as a tablet or a capsule.
Commercially available tablets can be used as examples of solid substances such as tablets. Examples include tablets with ordinary coatings and sugar-coated tablets. Examples of capsules include hard capsules whose contents are powder or granules.

As shown in FIG. 4, the sieve member 8 is, for example, a circular standard sieve with a sieve mesh opening of 500 μm. Note that the opening of the sieve member 8 is appropriately set, for example, in the range of 300 to 1000 μm, depending on the required size of the pulverized powder.
The sieve member 8 includes an annular support portion 8a provided on the outer periphery and a sieve portion 8b stretched within the annular support portion 8a.
The recovery container section 6 is, for example, a Umano chemical container (58 ml) with the lid removed.

Further, the crusher container 1 of the present embodiment includes a cylindrical crush-side buffer member 17 that covers the outer periphery of the crush container part 7 with a material that is softer than the crush container part 7, and a cylindrical crush-side buffer member 17 that covers the outer periphery of the crush container part 7, and a material that is softer than the crusher container part 6. It includes a cylindrical collection-side buffer member 18 that covers the outer periphery of the collection container section 6 with a flexible material.
The crushing side buffer member 17 has an opening diameter at the bottom set smaller than an opening diameter at the top, and the sieve member 8 is secured to the bottom.
The crushing side buffer member 17 and the collection side buffer member 18 are made of an elastic and flexible material such as urethane.

Furthermore, the crusher container 1 of this embodiment includes an annular sieve packing 19 disposed between the crusher container part 7 and the sieve member 8.
The sieve packing 19 is made of an elastic and flexible material such as silicone.

The cylindrical container main body 5 and main body lid member 5a are preferably made of stainless steel (SUS), for example, in terms of strength, but may be made of resin, ceramics, or other materials.
In addition, protrusions may be formed on the inner circumferential surface of the crushing container part 7, protrusions may be provided on the bottom surface of the crushing container part 7, or projections may be provided on the top surface of the crushing lid part 7b, or projections may be formed inside the crushing container part 7. By installing a crushing plate portion 16 having a blade portion 16b as shown in 7, the crushing effect is further improved.
For example, the crushing plate portion 16 has a blade portion 16b extending along the axis L0 of the crushing container portion 7, and is used while being fixed to the crushing lid portion 7b.

Note that the main surface of the crushing plate portion 16 may be installed obliquely with respect to the axis L0.
At this time, by tilting the main surface of the crushing plate part 16 slightly downward in the direction of rotation, the powder is repelled by the main surface of the crushing plate part 16 toward the sieve member 8 below during rotation. , the particles are efficiently moved to the lower recovery container section 6 through the sieving member 8 and recovered.

The crushing device 100 of this embodiment is a revolution-rotation mixer, and as shown in FIG. This pulverizer includes a rotatable rotating body 3, a drive mechanism 4 that rotationally drives the revolving body 2 and the rotating body 3, and the container 1 for the pulverizer, and performs pulverization without using balls.

The drive mechanism 4 is set to rotate the rotating body 3 at a rotational speed equal to or higher than that of the revolving body 2 .
In this embodiment, for example, by setting the rotation speed of the rotation body 3 to be the same as the rotation speed of the revolution body 2, when the rotation speed of the revolution body 2 is 1000 rpm, the rotation speed of the rotation body 3 is set to 1000 rpm. Ru. Note that rotational energy is proportional to the square of the rotational speed.

The rotational axis L2 is inclined with respect to the revolution axis L1 with the upper part of the crusher container 1 facing inward. That is, the rotation axis L2 is inclined at an angle θ toward the inner revolution axis L1, which is a vertical axis.
Therefore, the crusher container 1 is installed with the upper part inclined inward, and the angle θ of the rotation axis L2 is set to 15 degrees or less with respect to the revolution axis L1. That is, the angle of the axis L3 of the cylindrical portion 22 is also set to 15 degrees or less with respect to the revolution axis L1.
In this embodiment, for example, the rotation axis L2 is inclined inward by 10 degrees with respect to the revolution axis L1.

The drive mechanism 4 includes one drive source 10 having a rotation shaft 10a, and a power transmission mechanism 9 that is connected to the rotation shaft 10a of the drive source 10 and simultaneously transmits the rotational force of the drive source 10 to the revolving body 2 and the rotation body 3. It is equipped with
The drive source 10 is a motor or the like, and a first pulley 10b is fixed to a rotating shaft 10a.

The drive source 10 is fixed to the lower surface of the main body base 11, and a rotating shaft 10a is inserted into a rotating shaft hole 11a formed in the main body base 11 and protrudes to the upper surface side of the main body base 11.
The revolving body 2, which is a rotating unit, is rotatably supported around a revolving shaft portion 11a erected on the main body base 11. Note that the revolution shaft portion 11a is fixed coaxially with the revolution axis L1.

The revolution body 2 includes a pair of rotating arms 12 extending radially outward, and a second pulley 12a for revolution fixed to the lower part of the pair of rotating arms 12.
Further, a revolution belt 13 is wound around the first pulley 10b and the second pulley 12a, and the driving force of the drive source 10 is transmitted from the first pulley 10b to the second pulley 12a via the revolution belt 13. , the revolving body 2 is rotationally driven. That is, the first pulley 10b, the revolution belt 13, and the second pulley 12a constitute a part of the power transmission mechanism 9.

A rotation shaft portion 14 coaxial with the rotation axis L2 is erected at the tip of the rotation arm 12, and the rotation body 3 is rotatably provided on the rotation shaft portion 14.
The rotating body 3 includes a container holder H that is rotatable about an axis of rotation 14 via a rotation bearing 15, and a rotation gear 16 that is provided on the lower outer circumference of the container holder H around an axis of rotation L2. It is equipped with

Note that the rotation bearing 15 is provided inside the rotation gear 16 and between the rotation shaft portion 14 and the rotation gear 16 . That is, the rotation gear 16 and the container holder H are rotatably supported with respect to the rotation shaft 14 via the rotation bearing 15 .
The rotation axis portion 14 coaxial with the rotation axis L2 is inclined inward at a predetermined angle of 15 degrees or less with respect to the revolution axis L1, and is inclined at 10 degrees in this embodiment.
The container holder H is formed of a hard material into a cylindrical shape with a bottom, and the crusher container 1 can be placed inside.

The revolution shaft portion 11a is supported by a first revolution shaft bearing 12b formed at the center of the second pulley 12a and a second revolution shaft bearing 12c formed at the center of the rotary arm 12, so that the upper part thereof is It protrudes above the rotating arm 12.
Further, a miter gear 11b for rotation is fixed to the tip of the revolution shaft portion 11a, and teeth formed on the outer circumferential portion mesh with a pair of gears 16 for rotation, respectively. That is, when the rotating arm 12 rotates, the rotating gear 16 meshed with the rotating miter gear 11b rotates, and the rotating body 2 rotates. Therefore, the rotation bearing 15 and the rotation miter gear 11b constitute a part of the power transmission mechanism 9.

Next, a method of pulverizing the object to be processed using the pulverizing apparatus 100 of this embodiment will be described.

First, a predetermined amount of the material to be processed is put into the crushing container portion 7 of the crushing device container 1, and the crushing device container 1 is set in the container holder H.
When the drive source 10 is driven in this state to rotate the rotating shaft 10a, the revolution body 2 revolves around the revolution shaft portion 11a via the first pulley 10b, the revolution belt 13, and the second pulley 12a. At this time, since the rotation gear 16 meshes with the revolution shaft portion 11a that does not rotate, the rotation gear 16, the container holder H, and the crusher container 1 rotate through the rotation bearing 15. Note that in this embodiment, for example, when the revolution is clockwise, the rotation is counterclockwise.

In addition, each gear is set so that the rotational speed of the autorotation and the revolution is, for example, "the rotational speed of the autorotation: the rotational speed of the revolution = 1:1", and in this case, the rotational speed of the autorotation is, for example, 1000 rpm. At the same time, the revolution speed is set to 1000 rpm.
The above-mentioned revolution applies centrifugal force to the material to be processed in the container 1 for the pulverizer, and the rotation causes the material to be processed in the container 1 for the pulverizer to be pulverized.

The drive mechanism 4 rotates the revolving body 2 at a rotation speed for pulverization where the rotation speed of the revolving body 2 is relatively high, and then rotates the revolving body 2 at a rotation speed for collection where the rotation speed of the revolving body 2 is relatively lower than the rotation speed for crushing. It has a control function that repeatedly performs two-stage rotation of rotating the revolving body 2 at a rotational speed.
Specifically, for example, first, pulverization is performed in the pulverizing container section 7 at a pulverizing rotation speed of 1200 rpm for 20 seconds, and then the pulverization is carried out in the pulverizing container section 6 through the sieve member 8 at a collection rotation speed of 800 rpm for 10 seconds. Transfer and collect the powder after crushing. Further, by repeating the rotation speed for crushing and the rotation speed for recovery as necessary, control is performed to repeat crushing and recovery.

In this way, in the crusher container 1 of the present embodiment, the to-be-processed object is installed between the recovery container section 6 and the crushing container section 7 in the cylindrical container main body 5, and is housed in the crushing container section 7. Since the sieve member 8 is equipped with a sieve member 8 whose sieve mesh is finer than the particle size of As it falls downward from 7a, only the powder of the processed material, which is finer than the mesh of the sieve, falls from the sieve member 8 into the collection container section 6.

That is, by adopting a two-layer system (two-chamber structure) consisting of the crushing container section 7 and the recovery container section 6 with the sieve member 8 sandwiched between them, the finely processed material becomes a buffer within the crushing container section 7. The powder falls through the sieve member 8 into the recovery container section 6 in a separate room, is moved and separated, and does not interfere with the grinding in the grinding container section 7, allowing efficient grinding. This improves the pulverization rate. In this way, by adopting a two-chamber structure, it is possible to separate the pulverized material (powder of the processed material) during pulverization investigation, avoid a drop in pulverization efficiency, and reach the end point of pulverization with a single pulverization operation. It becomes possible to reach the point where all the objects to be processed (raw materials) have a particle size below the desired size.

In addition, since the pulverization does not proceed in the collection container section 6, and because the sieve member 8 acts as a separation wall and the frequency with which the pulverized material is moved to the pulverization container section 7 again is low, over-pulverization of the pulverized material can be prevented. This makes it possible to avoid a decrease in the fluidity of the pulverized material.
Furthermore, since the sieve mesh of the sieve member 8 scrapes the material to be processed during rotation, finer powder of the material to be processed can be obtained. In particular, as the material to be processed rolls on the surface of the sieve mesh of the sieve member 8, the powder of the material to be processed scraped by the sieve member 8 tends to be in the shape of high-quality spheres.

In addition, since a cylindrical crushing-side buffer member 17 is provided that covers the outer periphery of the crushing container 7 with a material more flexible than the crushing container 7, vibrations in the radial direction of the crushing container 7 are suppressed during rotation. By relaxing the side buffer member 17, deformation of the crushing container portion 7 can be prevented.
In addition, since it is provided with a cylindrical recovery side buffer member 18 that covers the outer periphery of the recovery container section 6 with a material that is more flexible than the recovery container section 6, vibrations in the axial direction of the recovery container section 6 during rotation are recovered. By relaxing the side buffer member 18, deformation of the recovery container section 6 can be prevented.
Furthermore, by providing the crushing plate part 16 which is provided in the crushing container part 7 and has a blade part 16b extending along the axis L0 of the crushing container part 7, the object to be processed can be removed from the crushing plate part during rotation. 16, it is crushed and the crushing effect is further improved.

In the crushing device 100 of the present embodiment, the drive mechanism 4 rotates the revolution body 2 at a relatively high rotation speed for crushing, and then the rotation speed of the revolution body 2 is lower than the rotation speed for crushing. Since the two-step rotation in which the revolution body 2 is rotated at a relatively slow recovery rotation speed is repeated, the powder is crushed by rotation at a fast grinding rotation speed and the powder is rotated at a slow recovery rotation speed. By repeating removal and removal, it is possible to efficiently re-pulverize.

In other words, after the material to be processed is pulverized by the strong centrifugal force generated by rotation at a high rotational speed for pulverization, the centrifugal force is weakened by rotation at a slow rotational speed for collection, and the effect of raising the material to be processed is weakened. The powder of the processed material can be moved to the recovery container section 6 via the sieve member 8 and removed from the crushing container section 7. Then, by rotating it again at a high rotational speed for crushing, the material to be processed can be crushed again in the crushing container section 7 with the powder that would have become a buffer material removed, allowing efficient crushing. It becomes possible to do so.

Next, second and third embodiments of a crusher container and a crusher equipped with the same according to the present invention will be described below with reference to FIGS. 8 and 9. In addition, in the following description of the embodiment, the same components described in the above embodiment are given the same reference numerals, and the description thereof will be omitted.

The difference between the second embodiment and the first embodiment is that in the first embodiment, the sieve member 8 simply has a sieve portion 8b, whereas in the second embodiment, the sieve member 8 simply has a sieve portion 8b. In the crushing apparatus equipped with this, as shown in FIG. 8, the sieve member 28 has a plurality of scraping uneven parts 28c formed on the surface on the side of the crushing container part 7.
That is, in the sieve member 28 of the second embodiment, a plurality of shaving uneven parts 28c are formed on the upper surface of an annular support part 28a provided on the outer periphery.
The uneven portion 28c for cutting is formed up to a region that can be exposed to the through hole 7a, and in this embodiment is formed of a plurality of cutting grooves. Note that the shaving uneven portion 28c may be formed of a plurality of protrusions or a combination of a plurality of shaving grooves and protrusions.

Next, the difference between the third embodiment and the first embodiment is that in the first embodiment, a sieve member 8 having mesh-like sieve openings is used, but in the crusher container of the third embodiment, the sieve member 8 is used. As shown in FIG. 9, each of the sieving members 38A, 38B, and 38C has a plurality of sieving holes 38b formed in the metal plate 38a by drilling.
That is, the sieving members 38A, 38B, and 38C are so-called punching metals.
In the sieving member 38A shown in FIG. 9A, a plurality of sieving holes 38b are formed throughout the entire area other than the outer peripheral edge of the circular metal plate 38a.

The sieving member 38B shown in FIG. 9(b) has a central region 39A in which no sieving holes 38b are formed, and a sieving region 39B in which a plurality of sieving holes 38b are formed on the outer periphery of the central region 39A. have.
On the contrary, the sieving member 38C shown in FIG. 9(c) has a sieving region 39C in which the sieving holes 38b are formed only in the center, and no sieving holes 38b are formed on the outer periphery.

As described above, in the crusher container of the third embodiment, the sieve members 38A, 38B, and 38C are formed by forming a plurality of sieve holes 38b serving as sieve meshes in the metal plate 38a. It is possible to obtain the same effect as No. 8, and also to easily form the sieve holes 38b in any desired area. Further, by changing the pore diameter, pore area ratio, arrangement, etc. of the sieve holes 38b, it is possible to control the particle size, separation efficiency, etc. Furthermore, the sieve holes 38b formed in the metal plate 38a by the hole-drilling process have sharper edges than the mesh-like sieve portion, and a higher shaving effect can be obtained.

Further, the sieving member 38B shown in FIG. 9(b) has a central region 39A in which no sieving holes 38b are formed, and a sieving region 39B in which a plurality of sieving holes 38b are formed on the outer periphery of the central region 39A. Therefore, it is possible to drop the powder downward from the outer sieve area 39B and separate it, and to prevent the powder from flowing backward from the central area 39A and returning into the crushing container section.
For example, when pulverization is performed by rotating and revolving at a high rotation angle, a vertical convection occurs in the pulverizing container in which the material to be processed rises at the center where the axis is located and descends at the outer periphery. Therefore, by forming the sieving area 39B only on the outer periphery, the crushed powder is effectively dropped from the outer periphery, and the powder returns from the center to the crushing container part due to the central area 39A without sieving holes 38b. can be suppressed.

On the other hand, if the convection is in the opposite direction to the above depending on the direction of rotation and revolution, in the sieve member 38C shown in FIG. 9(c), the sieve hole 38b is formed only in the center part. Since the sieve area 39C has a sieve area 39C and no sieve holes 38b are formed on its outer periphery, the powder is dropped downward from the central sieve area 39C and separated, and the powder flows back from the periphery to the crushing container. It is possible to prevent the person from returning to the department.

In addition, since the sieve member 39B does not have the sieve holes 38b formed in the central region 39A and the central portion is closed, air may not pass therethrough and convection may stop. In this case, a ventilation hole may be formed in the central region 39A to the extent that the pulverized powder cannot pass therethrough, but air can pass therethrough. For example, if the inner diameter φ of the sieving hole 38b is set to 0.6 to 1.0 mm, the inner diameter φ of the ventilation hole is set to about 0.1 to 0.3 mm.
Similarly, regarding the sieve member 39C, the sieve hole 38b is not formed on the outer periphery of the central part, and the outer periphery is closed, so air cannot pass through and convection may stop. In this case, it is also preferable to form the ventilation holes on the outer periphery.

As an example of the present invention, using the crusher container and the crusher of the first embodiment, 50 tablets (glycyron combination tablets) were actually crushed as the object to be processed, and the amount of the object to be processed before crushing was A. In contrast, the pulverization rate D ((B/A)×100) before and after pulverization was calculated from the pulverized material amount B after pulverization and the unpulverized material amount C.
The crushing was performed by installing a crushing plate shown in FIG. 7 inside the crushing container.
In addition, as a comparative example, a case was also investigated in which crushing was performed under similar rotation conditions using a SUS can container without a sieve member (with a crushing plate installed and no balls used).

As a result, in the comparative example without a sieve member, the amount of processed material A before pulverization was 12.881 g, the amount B of pulverized material after pulverization was 11.381 g, and the amount of unpulverized material C was 1.387 g. The pulverization rate D was 88.4%. On the other hand, in the embodiment of the present invention with a sieve member, the amount of processed material A before pulverization is 12.721 g, the amount B of pulverized material after pulverization is 12.094 g, and the amount of unpulverized material C is 0. .386g, and the pulverization rate D was 95.1%. As described above, it can be seen that the pulverization rate is improved in the examples of the present invention compared to the comparative examples.

Note that the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention.

For example, in each of the above embodiments, the crushing container part and the collection container part are housed separately in the cylindrical container main body, but at least the cylindrical container main body, the crushing container part, and the collecting container part are housed separately. It does not matter if one of them is integrated.
Further, in each of the above embodiments, the powder of the pulverized material to be processed is sieved and separated using one sieving member, but a plurality of sieve members with different sieving meshes may be installed vertically at intervals. A recovery container section may also be provided in between, and the powder of the object to be processed may be separated in a multi-stage manner using a plurality of sieving members and a plurality of recovery container sections. In this case, by creating a three-chamber or multi-chamber structure with multiple sieve members and multiple recovery container sections, the crushed material can be classified in multiple spaces (recovery container sections), and the crushed material of the desired particle size can be obtained. It becomes possible to increase yield.

Furthermore, in each of the above embodiments, the sieve member is separately manufactured and stored, but as shown in FIG. A plurality of sieve holes 48b may be formed by welding the top surfaces of the sieves with their backs to each other and drilling holes in this welded surface, thereby forming the sieve member 48.
