Description

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

Currently, tablets are basically prescribed in adult doses, so for people with swallowing difficulties, they are crushed in hospital dispensaries or pharmacies.
As a method for crushing objects to be processed, such as tablets, in addition to using a mill equipped with a rotating blade, consideration has been given to using an apparatus in which the objects to be processed are placed in a container and the container is rotated and revolved to agitate and crush the objects to be processed.

For example, Patent Document 1 describes a rotary mixing device in which a cylindrical stirring vessel with a bottom is used to store the material to be processed (the material to be stirred), and balls such as zirconia balls for assisting in grinding are placed in the stirring vessel together with the material to be processed, and the stirring vessel is rotated and revolved. In other words, the method of grinding using a ball mill with a rotation-revolution stirring method is described.

Patent No. 5984130

The above-mentioned conventional techniques have the following problems remaining.
That is, in the past, when grinding was performed by the rotation-revolution stirring method, a method was proposed in which balls were inserted to assist grinding, but the balls had to be removed from the powder after grinding, which was troublesome and involved contamination issues due to balls being mixed in. In addition, it was difficult to set the conditions, such as the number and size of the balls to be inserted, making it difficult to obtain good grinding.

The present invention was made in consideration of the above-mentioned problems in the conventional art, and aims to provide a container for a crushing device that allows for easy and good crushing and crushing without using balls, and a crushing device equipped with the same.

That is, in this crushing device container, the main surface is inclined toward the axis of the cylindrical container body, so that the material to be treated that hits the inclined main surface is easily bounced off to the center of the cylindrical container body, making it possible to crush a large amount of material at high speed. Note that, when crushing a small amount of material at a low speed, it is preferable to arrange the main surface at a right angle to the rotation direction of the rotation without inclining it toward the axis of the cylindrical container body.

The following describes a first embodiment of a container for a crushing device and a crushing device equipped with the container according to the present invention, with reference to Figs. 1 to 8. Note that in the drawings used in the following description, the scale of some parts has been appropriately changed as necessary to make each component recognizable or easily recognizable.

As shown in FIG. 7, the container 1 for the crushing device in this embodiment is a container used in a crushing device 100 that includes a revolving body 2 that can rotate around a revolution axis L1, a rotating body 3 that is held by the revolving body 2 and can rotate around a rotation axis L2, and a drive mechanism 4 that drives the revolving body 2 and the rotating body 3 to rotate.

As shown in Figures 1 to 6, the container 1 for the crushing device in this embodiment is attached to a rotating body 3 and can store the material to be treated. It comprises a bottomed cylindrical container body 5 whose axis L3 is set to be the same as the rotation axis L2, a lid portion 6 that can close the upper part of the cylindrical container body 5, and a crushing plate portion 7 that is installed within the cylindrical container body 5 and extends along the axis L0 of the cylindrical container body 5.
The object to be treated is, for example, a solid object such as a tablet.

The crushing plate 7 has a main surface 7 a facing the rotation direction of the rotor 3 and is disposed away from the inner circumferential surface of the cylindrical container body 5 and the axis L 0 of the cylindrical container body 5 .
In this embodiment, the multiple crushing plates 7 are installed at equal intervals from each other in the circumferential direction centered on the axis L0 of the cylindrical container body 5. That is, in this embodiment, the crushing plates 7, which are two long plate-shaped fins, are arranged parallel to each other at 180 degrees opposite sides from each other in the circumferential direction centered on the axis L0 of the cylindrical container body 5.
In addition, one or more crushing plates 7 may be installed inside the cylindrical container body 5.

The crushing plate 7 may be disposed with the main surface 7 a inclined toward the axis L 0 of the cylindrical container body 5 .
In this embodiment, the main surface 7a of the crushing plate 7 is disposed at a right angle to the circumferential direction of the cylindrical container body 5 as shown in Fig. 8(a), but it may be disposed at an inclination of up to 45 degrees in the opposite direction to the rotation direction of the rotor 3 as shown in Fig. 8(b). That is, the angle of the crushing plate 7 (main surface 7a) is set according to the workpiece M, the rotation speed, etc.

The crushing plate 7 also has a folded-back portion 7 b folded back on the side of the cylindrical container body 5 on the axis L 0 side in the opposite direction to the rotation direction of the rotor 3 .
Furthermore, the crushing plate 7 has a plurality of through holes 7c.
In this embodiment, four through holes 7c are formed in the crushing plate 7 in the extending direction thereof so as to be spaced apart from each other.

The two crushing plates 7 are connected to each other at their upper and lower parts. That is, the crushing device container 1 includes an upper connecting part 8A that connects the upper parts of the two crushing plates 7 and a lower connecting part 8B that connects the lower parts of the two crushing plates 7.
In this manner, the two crushing plate sections 7, the upper connecting section 8A, and the lower connecting section 8B constitute the crushing and stirring member 8. The crushing and stirring member 8 is made by bending a single metal plate such as stainless steel.

The upper connecting portion 8A is in the shape of a semicircular plate, and the lower connecting portion 8B is in the shape of an arc plate, and are bent from the crushing plate portion 7 at a right angle to the extending direction of the crushing plate portion 7 in opposite directions to each other.
The upper connecting portion 8A is provided with a semicircular plate portion 8b and a band-shaped portion 8c that is bridged between the upper portions of the two crushing plates 7.

The crushing plate 7 is fixed to the cover 6 .
That is, the upper connecting portion 8A has three screw holes 8a that can be screwed into the ceiling surface inside the lid portion 6 with mounting screws 6a.
Incidentally, the crushing plate 7 is preferably fixed to the lid 6 , but it may be fixed to the bottom surface inside the cylindrical container body 5 .

The container 1 for the crushing apparatus is preferably made of stainless steel in terms of strength, but may be made of resin, ceramics, or other materials.
The crushing effect can be further improved by forming protrusions on the inner peripheral surface of the cylindrical container body 5 or by providing protrusions on the bottom surface inside the cylindrical container body 5 or the top surface inside the lid portion 6.

The distance of the gap t between the crushing plate 7 and the inner peripheral surface of the cylindrical container body 5 is set to about 2 mm when the object M is a general tablet. In this case, the tablet cannot pass through the gap t, and is blown in the opposite direction while being crushed by the crushing plate 7. In addition, the airflow from the crushing plate 7 is sufficiently transmitted to the inner peripheral surface of the cylindrical container body 5, and adhesion of powder to the inner peripheral surface after crushing can be suppressed.
In addition, when the rotation speed is high, the airflow is large, so the gap t is set large, and when the rotation speed is low, the airflow is small, so the gap t is set small. Therefore, it is preferable to set the gap t in the range of 0.5 to 5 mm, for example.

The width W of the crushing plate 7 is set to about 1/4 of the inner diameter of the cylindrical container body 5. By setting the width W to about 1/4, a space of about 1/2 the inner diameter is created in the center of the cylindrical container body 5, making it possible to generate a sufficient air flow.
The width W of the crushing plate 7 is set small to enlarge the space in the center when a large amount of material M is fed, and set large to enlarge the main surface 7a, which is the crushing surface, when a small amount of material M is fed. For this reason, it is preferable to set the width W of the crushing plate 7 in the range of 1/10 to 1/3 of the inner diameter, for example.

The upper connecting portion 8A and the lower connecting portion 8B form only a part (half of the circumference in this embodiment) of a circle centered on the axis L0, rather than the entire circumference.
In this embodiment, two crushing plate sections 7 are arranged at a diagonal angle of 180 degrees, so the upper connecting section 8A and the lower connecting section 8B connect only half of the circumference. However, if, for example, four crushing plate sections 7 are arranged at 90 degree intervals in the circumferential direction, only one point on 1/4 of the circumference or two points including the diagonal are connected by the upper connecting section 8A and the lower connecting section 8B.

The through-hole 7c is set to have a diameter of about 1/3 of the width W of the crushing plate 7. With a through-hole 7c of this size, the crushed powder moving on the crushing plate 7 can easily escape through the through-hole 7c due to an air flow generated in the vertical direction (extension direction) on the crushing plate 7, and adhesion can be prevented.
The multiple through holes 7c are arranged in the vertical direction (extension direction) at intervals of about four times the diameter of the through holes 7c.

The diameter of the through hole 7c is set small when the workpiece M is to be crushed at a high rotation speed, and set large when the workpiece M is to be crushed at a low rotation speed. Therefore, it is preferable that the diameter of the through hole 7c is set within a range of, for example, 1/5 to 1/2 of the width W of the crushing plate section 7.
In this embodiment, the cylindrical container body 5 has an inner diameter of 54 mm and an inner height of 77 mm.

The pulverizing device 100 in this embodiment is a revolving mixer, and as shown in FIG. 7, includes a revolving body 2 that can rotate around a revolution axis L1, a spinning body 3 that is held by the revolving body 2 and can rotate around a spinning axis L2, a drive mechanism 4 that drives the revolving body 2 and the spinning body 3 to rotate, and a pulverizing device container 1 that is attached to the spinning body 3 and stores the material to be processed M.

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

The rotation axis L2 is inclined with respect to the revolution axis L1 so that the upper part of the crusher container 1 faces 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 container 1 for the crusher is mounted with its upper portion tilted 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 inwardly by 10 degrees with respect to the revolution axis L1.

The drive mechanism 4 includes a drive source 10 having a rotation shaft 10a, and a power transmission mechanism 9 connected to the rotation shaft 10a of the drive source 10 for transmitting the rotational force of the drive source 10 to the revolving body 2 and the rotating body 3 simultaneously.
The driving 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 the rotation shaft 10 a is inserted into a rotation shaft hole 11 a 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 supported rotatably about a revolution shaft portion 11a provided upright on a main body base 11. The revolution shaft portion 11a is fixed coaxially with the revolution axis line L1.

The revolving body 2 includes a pair of rotary arms 12 extending radially outward, and a second pulley 12 a for revolving, which is fixed to the lower part of the pair of rotary arms 12 .
In addition, 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, thereby driving and rotating the revolving body 2. In other words, 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 that is coaxial with the rotation axis line L2 is provided upright at the tip of the rotation arm 12, and the rotating body 3 is rotatably provided on the rotation shaft portion 14.
The rotating body 3 includes a container holder H that can rotate around a rotation shaft portion 14 via a rotation bearing 15, and a rotation gear 16 provided on the lower outer periphery of the container holder H with the rotation axis L2 as its center.

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

The revolution shaft portion 11a is supported by a first revolution shaft bearing 12b formed in the center of the second pulley 12a and a second revolution shaft bearing 12c formed in the center of the rotating arm 12, and its upper portion protrudes above the rotating arm 12.
Furthermore, a rotation miter gear 17 is fixed to the tip of the revolution shaft portion 11a, and teeth formed on the outer periphery mesh with a pair of rotation gears 16. That is, when the rotating arm 12 rotates, the rotation gear 16 meshed with the rotation miter gear 17 rotates, causing the rotating body 2 to rotate. Therefore, the rotation bearing 15 and the rotation miter gear 17 constitute a part of the power transmission mechanism 9.

Next, we will explain the method for stirring, crushing, and pulverizing the workpiece M using the crushing device 100 of this embodiment.

First, a predetermined amount of material to be processed M is placed in the container 1 for the crushing apparatus, and the container 1 for the crushing apparatus is set in the container holder H.
In this state, when the drive source 10 is driven to rotate the rotary shaft 10a, the revolving body 2 revolves around the revolving shaft portion 11a via the first pulley 10b, the revolving belt 13, and the second pulley 12a. At this time, since the rotation gear 16 is engaged with the non-rotating revolving shaft portion 11a, the rotation gear 16, the container holder H, and the crusher container 1 rotate via the rotation bearing 15. In this embodiment, for example, when the revolution is clockwise, the rotation is counterclockwise.

Each gear is set so that the rotation speed and revolution speed are, for example, "rotation speed: revolution speed = 1:1". In this case, for example, the rotation speed is set to 1000 rpm and the revolution speed is set to 1000 rpm.
The revolution applies centrifugal force to the material M in the crusher vessel 1, and the rotation causes the material M to be agitated and crushed in the crusher vessel 1.

In this manner, in the container 1 for a crushing device of this embodiment, the crushing plate 7 faces the main surface 7a in the rotation direction of the rotor 3 and is disposed away from the axis L0 of the cylindrical container body 5, so that the rotating crushing plate 7 collides with and bounces off the workpiece M such as tablets, thereby efficiently and satisfactorily crushing and pulverizing the workpiece M. In particular, a sufficient airflow is generated in the space formed in the center of the cylindrical container body 5 by the rotating crushing plate 7, and the workpiece M and crushed powder can be efficiently stirred.
In addition, since the crushing plate portion 7 is arranged at a distance from the inner surface of the cylindrical container body 5, the airflow generated by the crushing plate portion 7 rotating at a distance from the inner surface of the cylindrical container body 5 hits the inner surface of the cylindrical container body 5, making it possible to prevent the crushed powder from adhering to the inner surface of the cylindrical container body 5.

In addition, since the multiple crushing plate sections 7 are installed at equal intervals from each other in the circumferential direction centered on the axis L0 of the cylindrical container body 5, the workpiece M can be crushed even more efficiently by the multiple crushing plate sections 7, and since the crushing plate sections 7 are evenly arranged in the rotation direction, the weight balance is not biased, and stable rotation can be obtained.
In addition, the crushing plate portion 7 has a folded portion 7b on the side portion on the axis L0 side of the cylindrical container body 5, which is folded in the opposite direction to the rotation direction of the rotor 3. This increases the strength of the crushing plate portion 7 and makes it possible to bounce the crushed material in the opposite direction while preventing adhesion of crushed powder onto the crushing plate portion 7.

In addition, since the crushing plate section 7 has a plurality of through holes 7c, when rotating, the workpiece M and its crushed pieces move over the crushing plate section 7 and an air current is generated that flows over the crushing plate section 7 toward the through holes 7c, making it easier for the workpiece M and its crushed pieces to pass through the through holes 7c and suppressing adhesion of powder to the crushing plate section 7.
In addition, since the crushing plate section 7 is fixed to the lid section 6, the crushing plate section 7 can be installed inside the cylindrical container body 5 simply by attaching the lid section 6 to the top of the cylindrical container body 5, and the crushing plate section 7 can be removed from the cylindrical container body 5 simply by removing the lid section 6 from the top of the cylindrical container body 5, making the work easier.

Furthermore, since the plurality of crushing plate sections 7 are connected to each other at their upper and lower parts, it is possible to ensure high strength between them.
Incidentally, by arranging the main surface 7a so as to be inclined toward the axis L0 side of the cylindrical container body 5, the workpiece M that hits the inclined main surface 7a is easily bounced off to the center of the cylindrical container body 5, making it possible to crush a large amount of workpiece M at high speed. Incidentally, when crushing a small amount of workpiece M at a low speed, it is preferable to arrange the main surface 7a at a right angle to the rotation direction of the rotation without inclining it toward the axis L0 side of the cylindrical container body 5.
Since the crushing device 100 of this embodiment is provided with the above-mentioned crushing device container 1, the object to be processed M can be crushed and crushed efficiently.

Next, second to fourth embodiments of the container for a crushing device and a crushing device including the container according to the present invention will be described below with reference to Figs. 9 to 13. In the following description of each embodiment, the same components as those described in the above embodiments 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, while in the first embodiment, the upper connecting portion 8A is semicircular, the crushing device container 21 in the second embodiment has an upper connecting portion 28A having an arc-shaped plate portion 28b along the inner peripheral surface of the cylindrical container body 5, as shown in Figures 9 to 11.
That is, in the second embodiment, the central portions of the upper connecting portion 28A and the lower connecting portion 28B are left open. Note that the lower connecting portion 28B itself is an arc-shaped plate portion.
The upper connecting portion 28A comprises an arc-shaped plate portion 28b extending halfway around the circumferential direction centered on the axis L0 of the cylindrical container body 5, and a belt-shaped portion 28c spanning between the upper portions of the two crushing plate portions 7.
In this manner, in the crushing device container 21 of the second embodiment, the central portions of the upper connecting portion 28A and the lower connecting portion 28B are left open, so that air currents can be generated effectively.

The second embodiment also differs from the first embodiment in that the upper connecting portion 28A is not fixed to the lid portion 6 by screws.
That is, in the second embodiment, when the crushing and stirring member 28 is stored in the cylindrical container body 5 and the lid portion 6 is attached to the upper part of the cylindrical container body 5, the upper and lower parts of the crushing and stirring member 28 (upper connecting part 28A and lower connecting part 28B) are sandwiched and fixed between the top surface of the lid portion 6 and the bottom surface of the cylindrical container body 5.
A protrusion 28d that abuts against the top surface inside the lid portion 6 is formed on the band-shaped portion 28c.

Next, the difference between the third embodiment and the second embodiment is that in the second embodiment, the tip of the convex portion 28d on the band-shaped portion 28c abuts against the ceiling surface inside the lid portion 6, whereas in the container 31 for the crushing device of the third embodiment, as shown in Figure 12, the convex portion 28d is provided with a fixing biasing portion 38a that can abut against the ceiling surface inside the lid portion 6.
That is, in the third embodiment, when the crushing plate portion 7 is stored in the cylindrical container body 5 and the lid portion 6 is attached to close the upper part of the cylindrical container body 5, a fixing biasing portion 38a is provided which is pressed with a biasing force against at least one of the bottom surface within the cylindrical container body 5 and the top surface within the lid portion 6.

The fixing biasing portion 38a is a metal plate piece such as stainless steel, one end of which is fixed to the protruding portion 28d and protrudes radially outward.
This fixing biasing portion 38a is biased against the ceiling surface inside the lid portion 6 when the lid portion 6 is tightened, and fixes the entire crushing and stirring member 38 within the cylindrical container body 5 by the biasing force and frictional force generated in response to the tightening force of the lid portion 6.
In addition, a fluorine sheet or the like smaller than the fixing biasing portion 38a may be attached to the upper surface of the fixing biasing portion 38a so as to prevent it from coming into contact with the workpiece M.

Next, the difference between the fourth embodiment and the third embodiment is that in the third embodiment, the fixing biasing portion 38a is formed in a plate shape in order to fix the crushing and stirring member 38 inside the cylindrical container body 5 by frictional force due to a wide contact area, whereas the crushing device container 41 of the fourth embodiment is provided with a rod-shaped metallic fixing biasing portion 48a protruding obliquely upward from the convex portion 28d, as shown in FIG. 13.
That is, in the fourth embodiment, a rod-shaped fixing biasing portion 48a made of stainless steel or the like protrudes slightly obliquely upward from the protruding portion 28d.

This fixing biasing portion 48a has spring properties in the vertical direction, and when the lid portion 6 is tightened, it is pressed against the ceiling surface inside the lid portion 6 and comes into biased contact therewith, and the entire crushing and stirring member 48 is fixed within the cylindrical container body 5 by the biasing force generated in the fixing biasing portion 48a in response to the tightening force of the lid portion 6.
Therefore, in the fourth embodiment of the crushing device container 41, the spring-like fixing biasing portion 48a generates a stronger biasing force against the ceiling surface inside the lid portion 6 when the lid portion 6 is tightened, thereby enabling the entire crushing and stirring member 48 to be more stably fixed inside the cylindrical container body 5.

In this way, in the fourth embodiment of the crushing device container 41, the crushing plate 7 is stored in the cylindrical container body 5 and the lid 6 is attached to close the upper part of the cylindrical container body 5. The fixing biasing part 48a is pressed with a biasing force against at least one of the bottom surface of the cylindrical container body 5 and the top surface of the lid 6. Therefore, by simply attaching the lid 6 to the cylindrical container body 5, the crushing plate 7 can be more stably fixed in the cylindrical container body 5 by the biasing force of the fixing biasing part 48a. Therefore, screw fixing is not necessary, and the crushing and stirring member 48 having the crushing plate 7 is released when the lid 6 is removed, making it easy to disassemble and easy to clean each component.

Next, the difference between the fifth embodiment and the second embodiment is that while the lower connecting portion 28B (arc-shaped plate portion) in the second embodiment simply extends in an arc shape along the inner surface of the cylindrical container body 5, in the fifth embodiment, as shown in Figure 14, the crushing and stirring member 58 has a lower connecting portion 58B which is an arc-shaped plate portion, and the lower connecting portion 58B has a protrusion portion 58e which protrudes toward the axial center of the cylindrical container body 5.
That is, in the fifth embodiment, a protrusion 58e is provided which stands upright toward the axial center of the cylindrical container body 5 from a position protruding slightly radially inward from the middle part of the lower connecting part 58B.

Furthermore, whereas in the second embodiment the crushing plate portion 7 is arranged at a distance from the inner surface of the cylindrical container body 5, in the fifth embodiment the crushing plate portion 57 is arranged in contact with the inner surface of the cylindrical container body 5 or in close proximity with a small gap therebetween.
In addition, the crushing plate 57 of the fifth embodiment is not provided with a folded portion.

Furthermore, in the fifth embodiment, the crushing and stirring member 58 is not fixed to the lid portion 6, and when the upper opening of the cylindrical container body 5 containing the crushing and stirring member 58 is closed with the lid portion 6, a gasket such as silicone (not shown in the figure; gaskets made of fluororubber, ethylene propylene, etc. can also be used) is placed on the underside of the lid portion 6, and the crushing and stirring member 58 is pressed downward by the lid portion 6 via the gasket while the cylindrical container body 5 is closed, thereby making it possible to fix the crushing and stirring member 58 within the cylindrical container body 5.
In this case, the crushing and stirring member 58 can be manufactured more inexpensively than when it is fixed to the lid portion 6 .

In this way, in the fifth embodiment of the crushing device container, the arc plate portion 57 has a protrusion 58e that protrudes toward the axial center of the cylindrical container body 5, so that the protrusion 58e that protrudes near the bottom surface rotates in the circumferential direction, thereby moving the crushed material that has accumulated on the bottom surface and further crushing it.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
