Field of the Invention The present invention relates to a particle measuring apparatus for a granular material processing apparatus, and more particularly, to the particle size and shape of a granular material to be processed by a stirring granulating apparatus, a centrifugal rolling granulating coating apparatus, and the like. The present invention relates to a technology that is effective when applied to a particle measurement device that measures continuously.

2. Description of the Related Art In the granulation process of powders and granules, measuring and controlling the particle size is another condition in view of its significance of forming granules and also for process validation of products. Is an important item that cannot be compared. Therefore, in order to control the particle diameter, various granulators use a moisture meter, a pressure gauge, a wattmeter, and the like as a sensor for process validation, thereby controlling the end point of granulation and granulation conditions. Is being done. Note that process validation is generally defined as "a documented program that provides a high degree of assurance that a process will consistently produce products that meet preset standards and quality characteristics." And GMP (Good Manufactu
This is important from the viewpoint of ring practice.

However, the measurement by such a sensor has a problem that the particle diameter can only be indirectly "estimated" and the error is large. In addition, for example, a moisture meter cannot be used in non-aqueous granulation with ethanol, and the above-described sensor may not be used depending on the granulation method. Further, for example, there is a problem specific to each granulation method, for example, the power consumption control in the stirring granulation method tends to cause overgranulation.

For this reason, in order to easily and accurately grasp the particle size, particle shape, and the like (hereinafter, abbreviated as particle size) in real time, a powder or granule in a processing container (granulating container) is directly imaged to determine the particle size. A particle measuring device for measuring such as WO 97/15816 has also been proposed. Where,
A high-pressure gas is blown from the inside of the processing container to the powder / particle extracting tube attached to the processing container, and the powder in the processing container is introduced into the powder / particle extracting tube. Then, the introduced granular material is captured by an adhesive film provided at the back of the granular material take-out tube, and the captured granular material is imaged to measure the particle size and the like, thereby obtaining information of the granular material in real time. It is supposed to.

Further, in the above-mentioned particle measuring device, when the pressure inside the processing container becomes positive, the powder in the powder take-out tube flows out of the tube when the adhesive film is replaced, and contaminates the surrounding environment.
Purge air at a higher pressure than the inside of the processing vessel is introduced into the powdery substance taking-out pipe. Then, under the purge air, high-pressure gas is sprayed to appropriately sample the granular material.

[0006]

However, in such a particle measuring apparatus, it is difficult to set a purge air amount which can prevent the powder from flowing out of the tube without obstructing the sampling by blowing the high-pressure gas. was there.

Further, since it is necessary to directly attach a particle measuring device having a considerable size and weight to the granular material processing device, the strength of the portion to which the particle measuring device is attached is required, and the granular material processing device becomes large. There is a problem that the cost increases accordingly. Further, there is a problem that a space for the particle measuring device is further required around the device, and the space efficiency is not good.

A part of the configuration is shown in cross section for easy understanding.

The particle measuring apparatus 1 according to the present invention is a granulating container (processing container) of a centrifugal rolling granulator (powder processing apparatus) 2.
3 is attached to the side wall 4 and measures the particle size and the like of the granular material 5 rolling in the granulation container 3. In this case, the mounting place of the granulation container 3 is not limited to the side wall 4, but it is preferable to install the granulation container 3 at a position where the particle density is high.

Here, the centrifugal rolling granulator 2 is a device in which a rotating disk 6 is provided in a granulating container 3 and the powder on the rotating disk 6 is granulated by the rotation thereof. The centrifugal tumbling granulation apparatus 2 is a so-called centrifugal tumbling granulation coating apparatus that performs granulation and coating using a centrifugal tumbling granulation method.
A slit 7 is formed between the side wall 4 of the granulation container 3 and the rotating disk 6. The granulation process is performed while the slit air 9 is supplied from the air chamber 8 through the slit 7. In addition, a liquid can be sprayed from the spray nozzle 10 into the granulation container 3 and the powder dispersing device 11
The powder 12 can also be sprinkled.

On the other hand, the particle measuring apparatus 1 is provided with a cylindrical powder take-out pipe 14 having a powder feed passage 13 therein. The end of the granular material take-out tube 14 is slightly higher than the rotary disk 6 in a state where the granular material take-out tube 14 can be inserted into and removed from the granulation container 3, that is, can be freely inserted and removed. Attached to come. Note that a seal structure (not shown) is provided between the granular material take-out pipe 14 and the side wall 4 so that the granular material in the granulation container 3 does not flow out.

Further, an air cylinder 15 is provided outside the granulation container 3, and an operation arm 16 of the air cylinder 15 is attached to the powder material take-out pipe 14. Thus, when the air cylinder 15 is driven, the powder / particle take-out tube 14 moves in the direction of the arrow in FIG. FIG. 1 shows a state in which the powder removal pipe 14 is retracted. By operating the air cylinder 15, the powder removal pipe 14 is moved to its tip end as shown by a one-dot chain line in FIG. The part enters the granular material 5.

At one end 14a of the powder outlet tube 14, a powder inlet 17 is formed which opens to the side, and communicates with the powder inlet passage 13 inside. .
For this reason, when the granular material take-out pipe 14 is inserted into the granulation container 3, the granular material introduction port 17 enters the granular material 5.
Then, the granular material 5 flows into the granular material introduction passage 13 from the granular material introduction port 17. In addition, as shown in FIG. 1, when the granular material discharge pipe 14 retreats from the inside of the granulation container 3, the granular material introduction port 17
Is housed in the side wall 4, from which the powder 5
Does not flow in.

The granular material introduction passage 13 is provided with a granular material take-out pipe 14.
Is opened at the other end 14b, and a suction device (suction means) 18 is attached. Also, the suction device 18
At the subsequent stage, a particle image capturing device 20 is attached via a cylindrical connection pipe 19. Further, the connection pipe 19 is provided with a return pipe 33, and the particles not taken in by the particle image capturing device 20 are returned to the return pipe 33.
Is returned to the inside of the granulation container 3. A free connecting means (not shown) formed by a bellows or the like which absorbs the movement of the powder / particle take-out pipe 14 is attached between the powder / particle take-out pipe 14 and the suction device 18.

The suction device 18 suctions the powder material introduction passage 13 in the powder material extraction pipe 14 under reduced pressure. As a result, the granular material 5 introduced into the granular material introduction passage 13 is removed by the suction device 1.
By 8, the image is sent to the subsequent particle image capturing device 20 and the image is captured.

FIG. 2 is an explanatory view showing the structure of the particle image photographing apparatus 20. In this particle image photographing apparatus 20, the connecting pipe 19 is fixed to the apparatus cover 32 so that the adhesive film 21 is disposed so as to face the end face 19a on the right end side of the connecting pipe 19 in FIG. The adhesive film 21 is formed by applying a transparent adhesive material to one surface of a transparent resin tape, and the adhesive surface is formed on the end surface 19 a of the connection pipe 19.
And are provided so as to face. That is, the granular material sent from the granular material take-out pipe 14 due to the vacuum suction of the suction device 18 is captured by the adhesive film 21 here.

This adhesive film 21 is formed by being wound in a roll shape, and is supported by a roll support portion 22.
It is pulled out intermittently by a predetermined length in accordance with the measurement of the granular material. After moving along the end face 19a of the connecting pipe 19 via the guide rollers 23, 23, the motor reel 2
4 is wound up. In this case, the adhesive film 21
Is tightly fixed to the end face 19a at the time of measurement of the granular material, is peeled off from the end face 19a after the measurement is completed, and is wound up for the next measurement. The unused portion is the end face 19a.
And is again fixed to the end face 19a.

In order to fix the adhesive film 21 in close contact,
Various methods such as a method of pressing a transparent or frame-shaped pressing plate or the like from behind or a method of utilizing the tension of the adhesive film 21 can be used. In the first embodiment, the film pressing plate 25 is moved by the air cylinder 26. This is done by driving. That is, the film holding plate 25 is pressed behind the adhesive film 21 by the air cylinder 26, whereby the adhesive film 21 is pressed against the end face 19 a of the connection pipe 19 to be in close contact therewith. Therefore, the connection pipe 19 is sealed by the adhesive film 21 except when the adhesive film is wound.

For adjusting the winding length of the adhesive film, the particle measuring apparatus 1 is provided with a sensor 27 for detecting the movement of the guide roller 23. The sensor 27 is configured by a proximity switch, and detects passage of a hole 28 formed in the guide roller 23. Therefore, by counting the number of passages through this hole 28,
The number of rotations of the guide roller 23 that rotates by receiving the adhesive film 21 can be obtained, and thereby the amount of movement of the adhesive film 21 can be calculated.

Behind the adhesive film 21, an annular fluorescent lamp 29 illuminating the adhesive film 21 is provided.
0 is provided. Further, after that, a CCD camera 31 (imaging means) is installed, and an image of the state of the granular material attached to the adhesive film 21 is taken.
The fluorescent lamp support 30 is provided so that the light of the fluorescent lamp 29 does not enter the CCD camera 31 directly.
One side is shielded from light. The imaging data is transmitted to the control unit 40 as an information processing device.
The particle size and the like of all the powders and granules attached to the adhesive film 21 are measured, and information (particle shape information) of the powders 5 is obtained.

FIG. 3 is a block diagram showing the configuration of the control unit 40. The control unit 40 performs image processing and controls the entire system, and is provided in the form of a control panel or the like. The control unit 40 has an image processing device 41, a sequencer 42, and a panel computer 43, as shown in FIG. in this case,
The image processing device 41 processes a particle image from the CCD camera 31. The sequencer 42 acquires measurement data from the sensor 27, and controls the CCD camera 31, the air cylinders 15, 26, the suction device 18, the motor reel 24, and the like to perform sampling and imaging operations. Also,
The sequencer 42 also controls the operation of the centrifugal rolling granulator 2. Further, the panel computer 43 receives data from the image processing device 41, performs various operations, and controls the sequencer 42.

In addition, an analysis monitor 44 for displaying an image-processed particle image is attached to the control section 40 so that the state of particle measurement can be checked. Further, a color monitor 45 for displaying an image from the CCD camera 31 is also attached so that the color, shape, and surface state of the particle can be observed from a raw image of the particle. A video tape recorder 46 for storing the image is also attached. Further, a printer 47 for printing and outputting analysis results and the like, and a hard disk 48 as storage means for storing various data such as analysis results are also provided.

On the other hand, the control section 40 measures the particle diameter as follows. That is, first, in the image processing device 41, the analog image sent from the CCD camera 31 is divided into, for example, 500 × 500 250,000 pixels, and each pixel is subjected to binary digitization according to the luminous intensity. This data is stored in the panel computer 43.
Sent to Next, based on this data, the panel computer 43 defines the area of the high-level pixels that are continuously in contact with each other as the projected area of the particle, and assumes a circle having the same area as the circle to determine the diameter of the projected area and uses it as particle diameter data. Then, a particle size distribution, an average particle size, and the like are calculated from the particle size data. In addition, the sphericity (length ratio / minor diameter ratio) is calculated by measuring the major axis and the minor axis from the projected particle image.

Next, the operation in the case where the granulation of the granular material is controlled using the particle measuring apparatus 1 will be described. The particle measuring device 1 first samples the powder 5 and measures the particle size and the like. Next, it is determined whether or not the measured value has reached a set value. When the set value is reached, the granulation is stopped, and the product is dried and discharged as necessary. On the other hand, when the set value has not been reached, the granulating operation is continued, and sampling is repeated at predetermined time intervals.

Here, the sampling of the granular material 5 is performed by inserting the granular material take-out pipe 14 into the granulation container 3. That is, the air cylinder 15 is driven based on a command from the sequencer 42, and the powder / particle taking-out tube 14 moves to the left in FIG. At this time, the granular material introduction port 17 of the granular material discharge pipe 14 is located in the rolling granular material 5,
From the granulation container 3 side at atmospheric pressure, the powder / particles take-out pipe 14
The granular material 5 flows into the inside.

After a lapse of a predetermined time, the powder / particles discharge pipe 14 is
To move to the right and retreat from the inside of the granulation container 3.
After returning the powder removal pipe 14 into the side wall 4, the suction device 18
Activate As a result, the granular material in the granular material take-out pipe 14 is sent to the connection pipe 19 side, is captured by the adhesive film 21 of the particle image capturing device 20, and is dispersed and fixed. In addition,
At this time, the particles not captured by the adhesive film 21 are returned into the granulation container 3 via the return pipe 33.

When the vacuum suction is completed, the adhesive film 21 to which the granular material has adhered is imaged by the CCD camera 31 by the illumination of the fluorescent lamp 29, and the data is output to the control unit 40. Then, the control unit 40 calculates the particle diameter, the particle size distribution, the average particle diameter, the sphericity, and the like for all the powders adhered to the adhesive film 21,
Particle shape information of the powder 5 including the raw image of the particles is obtained. Thus, the particle size and the like of the granular material in the granulation container 3 are directly measured in real time.

After such a measurement, the motor reel 24
Is driven to pull out the adhesive film 21 for one pitch. At this time, the adhesive film 21 to which the granular material has adhered is peeled off from the end face 19a of the connection pipe 19, the unused portion of the adhesive film 21 moves to a position facing the end face 19a, and is tightly fixed to the end face 19a, and is used for the next measurement. Preparation is completed. These controls are also performed by the control unit 40.

As described above, according to the particle measuring apparatus 1 of the first embodiment, the granulation container 3
The granular material is introduced from the inside, and adheres to the adhesive film 21 of the particle image capturing device 20 by the suction device 18. Therefore, an accurate sample in the granulation container 3 can be easily obtained without performing fine setting of the purge air or the like unlike the conventional particle measuring apparatus. Further, since it is not necessary to directly attach the large and heavy particle image photographing device 20 to the centrifugal rolling granulation device 2 unlike the conventional particle measuring device, the granulation container 3
Can be relaxed.

6 are connected. Further, in this case, the return pipe 33 is connected to a collecting device (not shown), and the powder particles not captured by the adhesive film 21 are appropriately collected. Although FIG. 6 shows a configuration in which the particle image capturing apparatus 20 and the control unit 40 are separately provided, these may be integrated into a control panel.

The particle measuring device 54 shown in FIG. 7 uses an air hose 37 whose one end is directly inserted into the granular material 5 in the granulating container 3 as a granular material take-out tube. Then, a suction device 18 is attached to the other end of the air hose 37, and a particle image photographing device 20 is disposed at a subsequent stage. In this case, the configuration of the powder removal tube can be extremely simplified, and the cost of the apparatus can be reduced.
