Description

本発明は、処方された散薬を1服用づつに包装するため、散薬を分配皿に分配した後、掻き出し装置で掻き出して分割する散薬分配装置に関する。   The present invention relates to a powder distribution device that distributes powder to a distribution tray and then divides the powder by dispensing with a scraping device in order to wrap a prescribed powder for each dose.

従来の散薬分配装置では、掻き出し装置の掻き出し方向が分配皿の回転軸に対して外周方向へ掻き出しており、掻き出し装置で掻き出した散薬を包装ホッパーに投入できるように、分配皿のR形状の窪み部の外径縁の高さを低く押さえるため、外径縁のすくい角を23度前後に形成し、掻き出し装置のディスク直径を110mmとしていた。   In the conventional powder dispensing device, the scraping direction of the scraping device is scraped to the outer peripheral direction with respect to the rotation axis of the dispensing tray, and the R-shaped depression of the dispensing tray is so placed that the powder scraped by the scraping device can be put into the packaging hopper. In order to keep the height of the outer diameter edge low, the rake angle of the outer diameter edge was formed around 23 degrees, and the disc diameter of the scraping device was 110 mm.

このため、散薬をこの分配皿に堆積させるとき、分配皿の直径が500mmのもので1分間に30回転前後に押さえて回転させなければ、顆粒などの散薬は分配中に分配皿の窪み部から遠心力で飛散してしまう問題が生じる。   For this reason, when the powder is deposited on this distribution dish, if the distribution dish has a diameter of 500 mm and is not pressed and rotated about 30 rotations per minute, the powder or other powder will not be able to be removed from the depression of the distribution dish during distribution. The problem of scattering by centrifugal force arises.

散薬分割包装装置では、散薬の分割精度が求められ、この分割精度を向上させる手段の1つとして、分配皿をできるだけ高速回転させて散薬フィーダから分配皿に供給する事が望ましく、そのような技術として、特開昭57-86401号の技術を開示している。   In the powder division packaging device, the powder division accuracy is required, and as one means for improving the division accuracy, it is desirable to rotate the distribution tray as fast as possible and supply it from the powder feeder to the distribution tray. JP-A-57-86401 discloses the technique.

この特開昭57-86401号の技術は、散薬フィーダからV字形状の環状枡に散薬を堆積させ、この後V字形状の環状枡のV字先端部を開放して、R分配皿に堆積散薬を落とし、掻き出し装置でR分配皿に堆積した散薬を掻き出して包装ホッパーに落として包装している。散薬フィーダからV字形状の環状枡に散薬を堆積させる場合、V字形状の環状枡のため、1分間に60回転前後で回しても散薬が遠心力で飛散する事はない反面、分配工程と、掻き出し工程の2工程を散薬が通過する過程で、微粉末状の散薬が散薬フィーダやR分配皿等の面に残り、処方された散薬が包装された時には、目減りする欠点がある。   In the technique disclosed in Japanese Patent Laid-Open No. 57-86401, powder is deposited from a powder feeder onto a V-shaped annular bowl, and then the V-shaped tip of the V-shaped annular bowl is opened and deposited on the R distribution tray. The powder is dropped, and the powder deposited on the R distribution tray is scraped off by a scraping device and dropped into a packaging hopper for packaging. When depositing powder from a powder feeder onto a V-shaped annular bowl, the powder will not be scattered by centrifugal force even if it is rotated around 60 rotations per minute because of the V-shaped annular bowl. In the process in which the powder passes through the two steps of the scraping process, there is a disadvantage that the fine powder powder remains on the surface of the powder feeder, R-distribution dish, etc., and the prescribed powder is packaged.

この欠点を克服するため、出願人は特開平8-85502を開示している。   In order to overcome this drawback, the applicant has disclosed Japanese Patent Application Laid-Open No. 8-85502.

この特開平8-85502号には、散薬分配皿の外周部に環状のR形状の窪み部を設けると共に、R形状の窪み部の内径部分をドーナツ状に形成した分配皿を高速回転させて、前記R形状の窪み部に散薬を堆積させた後、R形状の窪み部に堆積した散薬を掻き出す掻き出し装置の掻き出し方向を前記ドーナツ状に抜いた散薬分配皿の回転中心方向として分配皿を一定角度づつ回転させて散薬を分配供給する分配供給装置が開示されている。   In JP-A-8-85502, an annular R-shaped depression is provided on the outer periphery of the powder distribution dish, and a distribution dish in which the inner diameter portion of the R-shaped depression is formed in a donut shape is rotated at a high speed. After the powder is deposited in the R-shaped depression, the dispensing tray is set at a certain angle with the scraping direction of the scraping device that scrapes the powder deposited in the R-shaped depression as the rotation center direction of the powder distribution tray extracted in the donut shape. Distributing and supplying devices for supplying powder powder by rotating it one by one are disclosed.

また、機械のコンパクト化にともない従来は掻き出し機構や包装ホッパーがR分配皿5の外周部に設置されていることで機械のコンパクト化の支障となっていた。
特開昭57-86401号公報 特開平8-85502号公報
Further, with the downsizing of the machine, conventionally, the scraping mechanism and the packaging hopper are installed on the outer peripheral portion of the R distribution tray 5, which hinders the downsizing of the machine.
JP-A-57-86401 JP-A-8-85502

ところで、特開平8-85502を開示しているような散薬分配皿を低価格で製造するには、散薬分配皿をプレス加工する事が望ましく、散薬と接触するため、耐久性や清潔度を保つ上でも、ステンレスを用いたものが望ましい。   By the way, in order to manufacture a powder distribution tray as disclosed in Japanese Patent Laid-Open No. 8-85502 at a low price, it is desirable to press the powder distribution tray, and since it comes into contact with the powder, durability and cleanliness are maintained. Also in the above, what uses stainless steel is desirable.

また散薬分配皿は、高度な精度が要求され、特に、散薬分配皿のR形状の窪み部径の軸と、散薬分配皿を回転させた時の回転軸の精度や散薬分配皿の回転軸の振れ、騒音や低振動、散薬分配皿のたわみやねじれ等が要求される。   In addition, the powder distribution tray requires a high degree of accuracy. In particular, the R-shaped hollow diameter of the powder distribution plate, the accuracy of the rotation axis when the powder distribution plate is rotated, and the rotation axis of the powder distribution plate Shaking, noise and low vibration, deflection and twisting of the powder distribution tray are required.

また、R分配皿を高速回転させるとフィーダからの分配中に飛散する一部の散薬が、回転遠心力で飛ばされ、この飛ばされた顆粒等の散薬が回転支持リングと前記回転支持リングに接触するローラの接触部分に噛み込む結果、突然の騒音発生やR分配皿のがたつき、耐久性の低下が伺えるためこれらの問題が発生しないことが要求される。   In addition, when the R distribution tray is rotated at a high speed, a part of the powder scattered during the distribution from the feeder is blown off by the rotating centrifugal force, and the powdered powder or the like comes into contact with the rotation support ring and the rotation support ring. As a result of biting into the contact portion of the roller, the sudden noise generation, rattling of the R-distribution tray, and a decrease in durability are expected, so that these problems are required not to occur.

更に、機械のコンパクト化の問題も課題の1つである。   Furthermore, the problem of machine downsizing is one of the problems.

本発明は、散薬分配皿を安く、散薬分配皿をプレス加工可能で高精度を維持できるような形状を保ち、実際に、散薬分配皿を回転させた場合に、散薬分配皿のR形状の窪み部径の軸と、散薬分配皿を回転させた時の回転軸の精度や散薬分配皿の回転軸の振れ、または、散薬分配皿を高速回転させた時の騒音や振動の軽減等の要求される精度に対して、容易に組立や調整が可能であって、フィーダからの分配中に飛散する一部の散薬が、回転遠心力で飛ばされ、回転支持リングと前記回転支持リングに接触するローラの接触部分に噛み込み、発生する問題等の課題を解決する為に成されたものである。   The present invention keeps the shape of the powder distribution tray cheap, maintains the shape that allows the powder distribution plate to be pressed and maintains high accuracy, and actually rotates the powder distribution plate when the powder distribution plate is rotated. The shaft of the diameter and the accuracy of the rotation axis when rotating the powder distribution tray, the swing of the rotation axis of the powder distribution plate, or the reduction of noise and vibration when rotating the powder distribution plate at high speed are required. Rollers that can be easily assembled and adjusted with respect to accuracy, and that part of the powder scattered during distribution from the feeder is blown away by the rotating centrifugal force and contacts the rotating support ring and the rotating support ring It is made in order to solve problems, such as the problem which bites into the contact part of this and generate | occur | produces.

本発明は、前記課題を解決するために、断面円弧状の窪み部を備えたドーナツ状の散薬分配皿を所定のピッチ角度で回転することにより、前記窪み部に堆積した散薬を掻出装置により1包分ずつ掻き出し可能とする散薬分配装置において、前記散薬分配皿の外周側縁が内周側縁よりも高く形成されている構成とした。
また、前記散薬分配皿の外周側縁には鍔部が設けられており、前記散薬分配皿は、前記鍔部を介して回転可能に支持されている構成とした。
In order to solve the above-mentioned problem, the present invention rotates a donut-shaped powder distribution tray provided with a hollow portion having an arc-shaped cross section at a predetermined pitch angle so that the powder accumulated in the hollow portion is scraped by a scraping device. In the powder distribution device that can scrape out one package at a time, the outer peripheral side edge of the powder distribution tray is formed higher than the inner peripheral side edge.
Moreover, the collar part was provided in the outer peripheral side edge of the said powder distribution tray, and the said powder distribution dish was set as the structure supported rotatably via the said collar part.

このことにより、散薬分配皿を高速回転さられる分配皿をプレス加工で高精度を維持して低価格で製造する事ができる。   Thereby, the distribution tray which can rotate the powder distribution tray at high speed can be manufactured at a low price while maintaining high accuracy by press working.

また、R形状の窪み部外周側縁の外側に備えた鍔部と、散薬分配皿のR形状の窪み部最下点が回転支持リングを支持して回転させた回転軸と同心軸になるように鍔部に沿って固定され、前記散薬分配皿の回転支持リングを回転可能に支持する構成とした。   Also, the flange provided outside the outer peripheral side edge of the R-shaped depression and the lowest point of the R-shaped depression of the powder distribution tray are concentric with the rotation axis supported by the rotation support ring. The rotary support ring of the powder distribution tray is rotatably supported along the collar.

このことにより、実際に、散薬分配皿を回転させた場合に、散薬分配皿のR形状の窪み部径の軸と、散薬分配皿を回転させた時の回転軸の精度や散薬分配皿の回転軸の振れ、または、散薬分配皿を高速回転させた時の騒音や振動の軽減等の要求される精度に対して、容易に組立や調整が可能にする等の課題を解決する事ができる。   By this, when the powder distribution dish is actually rotated, the accuracy of the R-shaped hollow portion diameter of the powder distribution dish and the rotation axis when the powder distribution dish is rotated and the rotation of the powder distribution dish It is possible to solve problems such as easy assembly and adjustment with respect to required accuracy such as reduction of noise and vibration when rotating the shaft or the powder distribution tray at high speed.

更に、前記支持リングと前記ローラの接触部を、前記散薬分配皿の回転時に飛散する散薬が噛み込み不能な位置に設けた。   Furthermore, the contact part of the said support ring and the said roller was provided in the position where the powder which splashes at the time of the rotation of the said powder distribution tray cannot bite.

これにより、フィーダから散薬を配分中、R分配皿5を1分間に60回転ほどの速度で回転させてもR分配皿の遠心力により飛散した顆粒等の散薬が、回転支持リングに接触するローラの接触部分に噛み込まないため、騒音や回転のがたつきが防止できる。   As a result, while distributing the powder from the feeder, even if the R distribution tray 5 is rotated at a speed of about 60 revolutions per minute, the powder such as granules scattered by the centrifugal force of the R distribution tray is in contact with the rotating support ring. Therefore, noise and rotation shakiness can be prevented.

以上のように本発明によれば、断面円弧状の窪み部を備えたドーナツ状の散薬分配皿を所定のピッチ角度で回転することにより、前記窪み部に堆積した散薬を掻出装置により1包分ずつ掻き出し可能とする散薬分配装置において、前記散薬分配皿の外周側縁が内周側縁よりも高く形成されている構成とした。また、前記散薬分配皿の外周側縁には鍔部が設けられており、前記散薬分配皿は、前記鍔部を介して回転可能に支持されている構成とした。   As described above, according to the present invention, by rotating a doughnut-shaped powder distribution tray provided with a depression having an arcuate cross section at a predetermined pitch angle, one powder of powder accumulated in the depression is packaged by a scraping device. In the powder dispensing device that can be scraped out by minute, the outer peripheral side edge of the powder distribution tray is formed higher than the inner peripheral side edge. Moreover, the collar part was provided in the outer peripheral side edge of the said powder distribution tray, and the said powder distribution dish was set as the structure supported rotatably via the said collar part.

このことにより、散薬分配皿を高速回転さられる分配皿をプレス加工で高精度を維持して低価格で製造する事ができる。   Thereby, the distribution tray which can rotate the powder distribution tray at high speed can be manufactured at a low price while maintaining high accuracy by press working.

また、R形状の窪み部外径縁の外側に備えた鍔部と、散薬分配皿の回転軸と同心軸に回転支持リングを前記鍔部に沿って設けられ、回転支持リングに前記鍔部を固定すると共に、前記散薬分配皿の回転支持リングを回転可能に支持する構成とした。   In addition, a flange provided outside the outer diameter edge of the R-shaped depression, a rotation support ring is provided along the flange on the concentric axis with the rotation axis of the powder distribution tray, and the rotation support ring includes the flange While being fixed, it was set as the structure which supports the rotation support ring of the said powder distribution tray rotatably.

このことにより、実際に、散薬分配皿を回転させた場合に、散薬分配皿のR形状の窪み部径の軸と、散薬分配皿を回転させた時の回転軸の精度や散薬分配皿の回転軸の振れ、または、散薬分配皿を高速回転させた時の騒音や振動の軽減等の要求される精度に対して、容易に組立や調整が可能にする等の課題を解決する事ができる。
さらに、散薬分配皿に散薬を供給するトラフの先端部に誘導溝を備え、トラフを振動させながら誘導溝から散薬を散薬分配皿に供給するようにしたので、散薬が散薬分配皿から飛散することがない。
誘導溝は散薬分配皿の窪み部の最下点を挟んで内周側と外周側に配置されているので、誘導溝から落下した散薬は窪み部最下点の方向に跳ね、跳ねた散薬同士が当たり窪み部最下点の位置に堆積する結果、散薬が散薬分配皿から飛散することがない。
トラフの先端部を2段階に下げて散薬分配皿への散薬の落下高さを押さえたので、散分配皿上で薬剤が跳ね難くなり、散薬を分散して堆積させることができる。
By this, when the powder distribution dish is actually rotated, the accuracy of the R-shaped hollow portion diameter of the powder distribution dish and the rotation axis when the powder distribution dish is rotated and the rotation of the powder distribution dish It is possible to solve problems such as easy assembly and adjustment with respect to required accuracy such as reduction of noise and vibration when rotating the shaft or the powder distribution tray at high speed.
In addition, a guide groove is provided at the tip of the trough that supplies powder to the powder distribution tray, and the powder is scattered from the powder distribution tray because the powder is supplied from the guide groove while vibrating the trough. There is no.
Since the guide groove is arranged on the inner and outer peripheral sides with the lowest point of the depression part of the powder distribution tray, the powder falling from the guide groove jumps in the direction of the lowest point of the depression part, As a result, the powder is not scattered from the powder distribution tray.
Since the tip of the trough is lowered in two stages and the drop height of the powder onto the powder distribution tray is suppressed, the drug becomes difficult to jump on the powder distribution tray, and the powder can be dispersed and deposited.

以下、本発明の実施例を説明する。   Examples of the present invention will be described below.

図1は本発明の散薬分配装置を備えた散薬分割包装装置の例を示す。この装置は、投入ホッパー2に散薬を入れて、フィーダ1を作動させると同時に、R分配皿5を1分間に60回転ほどの速度で回転させた状態で、トラフ3の先端部から散薬をR分配皿に供給している。   FIG. 1 shows an example of a powder divided packaging apparatus provided with the powder distribution apparatus of the present invention. In this device, powder is put into the charging hopper 2 and the feeder 1 is operated, and at the same time, the powder is applied from the tip of the trough 3 while the R distribution tray 5 is rotated at a speed of about 60 revolutions per minute. Supplying to the distribution tray.

フィーダ1は図2に示すように構成され、トラフ3下に固定された2枚の圧電素子4により、約100Hzの周波数で振動する。トラフ3下の支持板20には、圧電素子4の振動方向に平行して振動センサー21が取り付けられている。圧電素子4の下部は固定台座22に固定されていて、固定台座22はバネ23でフィーダ1の振動を吸収するようにして散薬分割包装装置本体に取り付けられる。   The feeder 1 is configured as shown in FIG. 2, and vibrates at a frequency of about 100 Hz by two piezoelectric elements 4 fixed under the trough 3. A vibration sensor 21 is attached to the support plate 20 below the trough 3 in parallel with the vibration direction of the piezoelectric element 4. The lower part of the piezoelectric element 4 is fixed to a fixed base 22, and the fixed base 22 is attached to the powder divided packaging apparatus main body so as to absorb the vibration of the feeder 1 by a spring 23.

図3はホッパー角度支持装置を示す。トラフ3の上方には投入ホッパー2がホッパー角度支持装置の支持部材24に支持されており、この支持部材24は支柱25を軸にして回動し支持部が昇降するようになっている。この支持部材24を回動させるアーム部材26は、モータ27により回転する図示しないクランク軸に接続されている。モータ27によりクランク軸が回転すると投入ホッパー2の開口角度を可変させることができる。   FIG. 3 shows a hopper angle support device. Above the trough 3, the feeding hopper 2 is supported by a support member 24 of a hopper angle support device, and this support member 24 is rotated about a support column 25 so that the support portion is raised and lowered. The arm member 26 that rotates the support member 24 is connected to a crankshaft (not shown) that is rotated by a motor 27. When the crankshaft is rotated by the motor 27, the opening angle of the charging hopper 2 can be varied.

モータ27はステッピングモータを採用しており、目的の開口角度に合わせた位置で投入ホッパー2を停止させて保持できる。また、散薬の供給が終了した際、投入ホッパー2表面に付着した散薬は、前記モータ27を細かい角度(約15の範囲)で制御して投入ホッパー2を振動させることにより、トラフ3に落とされる。また、ソレノイド部材により投入ホッパー2を打撃することで、投入ホッパー2に付着した散薬をトラフ3に落としてもよい。   The motor 27 employs a stepping motor and can stop and hold the charging hopper 2 at a position that matches the target opening angle. Further, when the supply of powder is finished, the powder adhering to the surface of the charging hopper 2 is dropped on the trough 3 by controlling the motor 27 at a fine angle (a range of about 15) to vibrate the charging hopper 2. . Moreover, you may drop the powdered medicine adhering to the injection hopper 2 to the trough 3 by hitting the injection hopper 2 with a solenoid member.

このフィーダ1の投入ホッパー2の投入口付近には、図4(a)(b)に示す集塵装置28を備えることが好ましい。   It is preferable that a dust collector 28 shown in FIGS. 4A and 4B is provided in the vicinity of the charging port of the charging hopper 2 of the feeder 1.

この集塵装置28は投入ホッパー2の投入口の外周部より大きい筒状の枠で形成され、支持パイプ29に回転自在に支持されているため、図4(b)のように、集塵装置28が投入ホッパー2より離反するように設けられている。   The dust collector 28 is formed of a cylindrical frame larger than the outer peripheral portion of the charging port of the charging hopper 2 and is rotatably supported by the support pipe 29. Therefore, as shown in FIG. 28 is provided so as to be separated from the charging hopper 2.

集塵装置28の筒状枠の内周には、集塵口30が設けられ、散薬を投入ホッパー2内に投入したときに発生する薬粉塵が集塵口30から集塵装置28に吸引されるようになっている。   A dust collecting port 30 is provided on the inner periphery of the cylindrical frame of the dust collecting device 28, and drug dust generated when powder is put into the charging hopper 2 is sucked into the dust collecting device 28 from the dust collecting port 30. It has become so.

この集塵装置28は図5に示すようにクリーナ装置40に接続されている。クリーナ装置40は、フィルター41とファン42で構成され、切り替えバルブ43に接続されている。   The dust collector 28 is connected to a cleaner device 40 as shown in FIG. The cleaner device 40 includes a filter 41 and a fan 42 and is connected to a switching valve 43.

前記集塵装置28の集塵口30から吸い込まれた散薬粉塵は、支持パイプ29を通して切り替えバルブ43を経てクリーナ装置40に導かれる。途中流量調整装置44により、集塵装置28の集塵口30から吸い込む流量が調整される。   Powdered dust sucked from the dust collecting port 30 of the dust collecting device 28 is guided to the cleaner device 40 through the support pipe 29 through the switching valve 43. The flow rate that is sucked from the dust collecting port 30 of the dust collecting device 28 is adjusted by the midway flow rate adjusting device 44.

この他、切り替えバルブ43に接続されているユニットに、R分配皿5の表面を清掃する回転ブラシ付きクリーナー45や、掃除機46が設けられているが説明を省略する。   In addition, the unit connected to the switching valve 43 is provided with a cleaner 45 with a rotating brush for cleaning the surface of the R distribution tray 5 and a vacuum cleaner 46, but the description thereof is omitted.

図1に示すR分配皿5は、プレス加工で形成され、R形状(断面円弧状)の窪み部を備えている。窪み部の内周側はドーナツ状に開口しており、その内周側縁5aのRの反り上がり角度は約23.5度に設定されている。   The R distribution tray 5 shown in FIG. 1 is formed by press work, and includes a concave portion having an R shape (circular arc shape). The inner peripheral side of the recess is opened in a donut shape, and the angle of curvature of R of the inner peripheral edge 5a is set to about 23.5 degrees.

一方、R形状の窪み部の最下点5bより外周側の外周側縁5cは、Rの反り上がり角度が約50度に設定され、内周側縁5aのRの反り上がり高さより外周側縁5cの反り上がり高さが高く設定されている。これは、フィーダ1から分配される散薬が、R分配皿5を前記条件の回転速度で回転させても散薬がR分配皿5の遠心力で飛散しないようにするためである。   On the other hand, the outer peripheral side edge 5c on the outer peripheral side from the lowest point 5b of the R-shaped depression is set so that the R warping angle is set to about 50 degrees, and the outer peripheral side edge is higher than the R warping height of the inner peripheral side edge 5a. The warping height of 5c is set high. This is to prevent the powder dispensed from the feeder 1 from being scattered by the centrifugal force of the R distribution tray 5 even when the R distribution tray 5 is rotated at the rotational speed of the above condition.

外周側縁5cの更に外周部には、R分配皿5を回転させるための支持リング6を保持する鍔5dがR分配皿5と一体に形成されている。   A flange 5d for holding a support ring 6 for rotating the R distribution tray 5 is formed integrally with the R distribution tray 5 on the outer peripheral portion of the outer peripheral edge 5c.

図6は、フィーダ1の配置を示す図である。   FIG. 6 is a diagram illustrating an arrangement of the feeder 1.

ここで示すトラフ3は、図7に示すように先端部が2段階に下がっており、トラフ3の先端部は更に2つの誘導溝3a,3bを備えている。   As shown in FIG. 7, the trough 3 shown here has a tip portion lowered in two stages, and the tip portion of the trough 3 is further provided with two guide grooves 3a and 3b.

この2つの誘導溝3a,3bは、それぞれR形状の窪み部最下点5bを挟んで内外周の位置に配置されている。これにより、トラフ3の先端部から落下する散薬は、誘導溝3a,3bから多く落下し、R分配皿5に誘導溝3a,3bからそれぞれ落下した散薬は、R形状の窪み部最下点5bの方向に跳ね、跳ねた散薬同士が当たってR形状の窪み部最下点5bの位置に堆積する。   The two guide grooves 3a and 3b are arranged at positions on the inner and outer circumferences with the lowest point 5b of the R-shaped depression part interposed therebetween. Thereby, a lot of powder falling from the tip of the trough 3 falls from the guide grooves 3a and 3b, and the powder dropped from the guide grooves 3a and 3b to the R distribution tray 5 is the lowest point 5b of the R-shaped depression. In this direction, the splashed powder hits each other and accumulates at the position of the lowest point 5b of the R-shaped depression.

このため、散薬はR分配皿5から飛散する事が少ない。またトラフ3は、先端部が2段階に下がっていて落下高さが押さえられるので、散薬は跳ね難くなる。R分配皿5に堆積する散薬は、R形状の窪み部最下点5bの上方を頂点に高く積もり難く、左右に分散して堆積する。   For this reason, the powder is less likely to scatter from the R distribution tray 5. Moreover, since the tip part of the trough 3 is lowered in two stages and the fall height is suppressed, it becomes difficult for the powder to jump. The powder depositing on the R distribution tray 5 is distributed in the right and left direction, and is difficult to accumulate at the top of the lowermost point 5b of the R-shaped depression.

本発明のようにR分配皿5を高速回転させるためには、フィーダ1のトラフ3の落下口とR分配皿5をできるだけ接近させるか、R分配皿5の最下点を挟んだ内外径のそれぞれの傾斜面に散薬を落として、回転しているR分配皿5から飛び跳ねないようにする工夫が必要である。   In order to rotate the R distribution tray 5 at a high speed as in the present invention, the dropping opening of the trough 3 of the feeder 1 and the R distribution tray 5 are brought as close as possible, or the inner and outer diameters sandwiching the lowest point of the R distribution tray 5 It is necessary to devise a technique for dropping powder on each inclined surface so as not to jump off the rotating R distribution tray 5.

このようにして散薬がR分配皿5に分配されると、R分配皿5を一定の角度毎に送り込み、その1回に送り込まれた範囲の散薬が掻き出し装置7で包装ホッパー8に掻き落とされる。包装ホッパー8のシャッターを解放すると、散薬が包装紙10に投入され、シール装置11の回転により包装紙10が順次引き込まれて包装されるようになっている。   When the powder is distributed to the R distribution tray 5 in this way, the R distribution tray 5 is fed at a certain angle, and the powder in the range fed at one time is scraped off by the packaging hopper 8 by the scraping device 7. . When the shutter of the packaging hopper 8 is released, the powder is put into the wrapping paper 10, and the wrapping paper 10 is sequentially drawn by the rotation of the sealing device 11 and is packaged.

前記掻き出し装置7は、分配中は上方に待避しており、分配が終了すると降下してR分配皿5に接触するようになっており、掻き出し装置7が1回転するとR分配皿5の内径方向に散薬を掻き落とすようになっている。   The scraping device 7 is retracted upward during distribution, and when dispensing is completed, the scraping device 7 is lowered to come into contact with the R distribution tray 5. When the scraping device 7 makes one rotation, the inner diameter direction of the R distribution tray 5 is reached. The powder is scraped off.

これらの分配や分割動作が終了すると、図5に示す回転ブラシ付きクリーナー45を作動してR分配皿5のR形状の窪み部表面を清掃して次の処方を待機する。   When these dispensing and dividing operations are completed, the rotary brush cleaner 45 shown in FIG. 5 is activated to clean the surface of the R-shaped depression of the R-distribution dish 5 and wait for the next prescription.

掻き出し装置7の動作は次のように行われる。   The operation of the scraping device 7 is performed as follows.

図8(a)に示すように掻き出し装置7は、デイスク12によりR分配皿5に堆積した散薬を切り出し、R分配皿5を回転させて送った範囲の散薬がディスク12に掻き寄せられた後に、掻き出し装置7の回転によりガイド板13がR分配皿5に堆積した散薬を仕切り、前記ディスク12とガイド板13の間にもうけた掻き板14によりR分配皿5から掻き落とすようになっており、これらの駆動はモータ15によって行われる。   As shown in FIG. 8A, the scraping device 7 cuts out the powder deposited on the R distribution tray 5 by the disk 12, and after the powder in the range sent by rotating the R distribution tray 5 is scraped to the disk 12. The guide plate 13 partitions the powder deposited on the R distribution tray 5 by the rotation of the scraping device 7 and is scraped off from the R distribution tray 5 by the scraping plate 14 provided between the disk 12 and the guide plate 13. These drives are performed by the motor 15.

図8(b)や(c)に示すように掻き板14の先端部はR分配皿5の内面を接触しながら掻き出し装置7の回転にしたがって、R内面を移動する事になるが、図8(c)に示すように掻き板14の先端部に切り込みを入れると、R分配皿5から離反するときに、掻き板のゴム材の反発が押さえられ、顆粒状の散薬が飛び跳ねにくくなる。   As shown in FIGS. 8B and 8C, the tip of the scraping plate 14 moves on the inner surface of the R according to the rotation of the scraping device 7 while contacting the inner surface of the R distribution tray 5. When a notch is made at the tip of the scraping plate 14 as shown in (c), the repelling of the rubber material of the scraping plate is suppressed when separating from the R distribution tray 5, and the granular powder is less likely to jump.

図9の(a)(b)は掻き出し装置の側面図である。   FIGS. 9A and 9B are side views of the scraping device.

掻き出し装置7のディスク12の回転は一定速度で回転するのではなく、所定の決まった範囲を設定された速度で回転する。   The disk 12 of the scraping device 7 does not rotate at a constant speed, but rotates at a set speed within a predetermined range.

図9の(b)に示すように、掻き出し中の動作は次のように範囲が分断されている。R分配皿5の内周側縁5aの位置で、掻き出し装置7は停止するか最低速度に減速されている。   As shown in FIG. 9B, the range of the operation during scraping is divided as follows. At the position of the inner peripheral edge 5a of the R distribution tray 5, the scraping device 7 is stopped or decelerated to the minimum speed.

このR分配皿5の内周側縁5aの位置を通過して、しばらくは回転速度を加速し、一定の位置からはほぼ一定の速度で回転軸xが回転する。加速終了からR分配皿5の外周側縁5cの範囲を速度調整区間として設定している。   After passing through the position of the inner peripheral edge 5a of the R distribution tray 5, the rotational speed is accelerated for a while, and the rotating shaft x rotates at a substantially constant speed from a certain position. The range of the outer peripheral side edge 5c of the R distribution tray 5 from the end of acceleration is set as the speed adjustment section.

この速度調整区間は、回転基準として掻き板14がR分配皿5の外周側縁5cに到達したことを基準としているのではなく、ガイド板13の先端部が到達しているかがポイントである。たとえばR分配皿5の分割送り角度が小さい場合、ガイド板13の先端部がR分配皿5の外周側縁5cの位置まで到達するより早く分割送り角度が次の停止点に到達する。   This speed adjustment section is not based on the fact that the scraping plate 14 has reached the outer peripheral side edge 5c of the R distribution tray 5 as a rotation reference, but the point is whether the tip of the guide plate 13 has reached. For example, when the divided feed angle of the R distribution tray 5 is small, the divided feed angle reaches the next stop point sooner than the tip of the guide plate 13 reaches the position of the outer peripheral edge 5 c of the R distribution tray 5.

このため回転軸x速度調整区間で減速する必要はないが、設定された包装数が少なくなると、それに対応してR分配皿5の分割送り角度が大きくなってくるため、回転軸x速度調整区間で一定速度で回転させると、分割送り角度が次の停止点に到達するより早くガイド板13の先端部がR分配皿5の外周側縁5cの位置まで到達してしまい、そのまま回転軸xを回転させると堆積する散薬にガイド板13が接触しながらもなお、R分配皿5が送り込まれ、分割に必要なR分配皿5に堆積する散薬範囲をディスク12とガイド板13の間に取り込むことができず、分包誤差が生じる。   For this reason, it is not necessary to decelerate in the rotation axis x speed adjustment section. However, if the set number of packages decreases, the divided feed angle of the R distribution tray 5 increases correspondingly, so the rotation axis x speed adjustment section. , The tip of the guide plate 13 reaches the position of the outer peripheral edge 5c of the R distribution tray 5 sooner than the divided feed angle reaches the next stop point, and the rotation axis x is moved as it is. While the guide plate 13 is in contact with the powder that accumulates when rotated, the R distribution tray 5 is still fed, and the range of the powder that accumulates on the R distribution tray 5 necessary for division is taken between the disk 12 and the guide plate 13. Cannot be performed, resulting in a packaging error.

このため、包装数やR分配皿5の送り角度の増減に対応した時間データを記憶しておき、ガイド板13の先端部がR分配皿5の外周側縁5cの位置まで到達する時間が前記記憶される時間より早いことが予測される場合には、回転軸xの回転速度を速度調整区間で減速して回転するように制御している。   For this reason, time data corresponding to increase / decrease of the number of packages and the feed angle of the R distribution tray 5 is stored, and the time required for the tip of the guide plate 13 to reach the position of the outer peripheral edge 5c of the R distribution tray 5 is described above. When it is predicted that the time will be earlier than the stored time, the rotational speed of the rotary shaft x is controlled so as to decelerate and rotate in the speed adjustment section.

図1に示すようにR分配皿5上方には、錠剤を手撒きして分割包装する錠剤分割機37が備えられており、包装ホッパー8に落下させるシャッター38を備えた錠剤シュート39が分割機の幅に対応して備えられている。   As shown in FIG. 1, a tablet dividing machine 37 for manually dividing and packaging tablets is provided above the R distribution tray 5, and a tablet chute 39 having a shutter 38 for dropping onto the packaging hopper 8 is provided. It is provided corresponding to the width of.

錠剤分割機37は小さな枡目状に配置した容器であり、各枡の底面にもそれぞれ図示しない底板シャッターが設けられている。   The tablet dividing machine 37 is a container arranged in a small grid shape, and a bottom plate shutter (not shown) is also provided on the bottom surface of each basket.

この底板シャッターは錠剤分割機37の移動方向に対して底に接触しながら移動するため、シュート39の開口部に達すると錠剤分割機37の底板シャッターが自然解放して、容器内の錠剤をシュート39に落とすようになっている。このシュート39の開口部は錠剤分割機37の移動方向に対して、錠剤分割機37の移送方向の1つの枡を幅方向に設けた枡の数で割ったピッチで、階段状のスリットを設けており、錠剤分割機37を前記錠剤分割機37の移送方向の1つの枡を幅方向に設けた枡の数で割ったピッチで移送しているため、手前の角から幅方向に順に錠剤分割機37の底板シャッターが解放する。   Since this bottom plate shutter moves while contacting the bottom with respect to the moving direction of the tablet dividing machine 37, when the opening of the chute 39 is reached, the bottom plate shutter of the tablet dividing machine 37 spontaneously releases and shoots the tablets in the container. It is supposed to drop to 39. The opening of the chute 39 is provided with a step-like slit at a pitch obtained by dividing one wrinkle in the transfer direction of the tablet dividing machine 37 by the number of wrinkles provided in the width direction with respect to the moving direction of the tablet dividing machine 37. Since the tablet dividing machine 37 is transported at a pitch obtained by dividing one ridge in the transfer direction of the tablet dividing machine 37 by the number of ridges provided in the width direction, the tablet is divided in order from the front corner to the width direction. The bottom plate shutter of the machine 37 is released.

シュート39の出口に設けたシャッター38はこれらの一連の動作に伴ったタイミングで作動するようになっている。   The shutter 38 provided at the exit of the chute 39 is operated at a timing associated with a series of these operations.

図14は従来の掻き出し装置7及びR分配皿5の駆動や包装ホッパー8等の配置を示す。掻き出し装置7のディスク12を昇降させる昇降アーム7aの回転軸や包装ホッパー8はR分配皿5の外側に設けられ、R分配皿5はR分配皿駆動モータ16で駆動され、フィーダ1は、R分配皿5の外側に配置され、投入ホッパー2に散薬を入れると、トラフ3を通じてR分配皿5のR部分に供給される。   FIG. 14 shows the driving of the conventional scraping device 7 and the R distribution tray 5, the arrangement of the packaging hopper 8, and the like. The rotating shaft of the lifting arm 7a for raising and lowering the disk 12 of the scraping device 7 and the packaging hopper 8 are provided outside the R distribution tray 5, the R distribution tray 5 is driven by the R distribution tray drive motor 16, and the feeder 1 When the powder is placed in the charging hopper 2 and placed outside the distribution tray 5, the powder is supplied to the R portion of the R distribution tray 5 through the trough 3.

図10に示すR分配皿5の中心方向に散薬を掻き出して包装する装置の場合、前記図14に示すようにR分配皿5の回転駆動は中心部に持つ事ができないため、R分配皿5の外周部に支持リング6を設け、支持リング6をローラ17で回転支持している。   In the case of the device for scraping and packaging the powder in the center direction of the R distribution tray 5 shown in FIG. 10, since the rotation drive of the R distribution tray 5 cannot be held at the center as shown in FIG. 14, the R distribution tray 5 A support ring 6 is provided on the outer periphery of the support ring 6, and the support ring 6 is rotatably supported by rollers 17.

R分配皿5の支持は、このような装置において重要な役割を果たしており、回転支持の手段に問題があると、R分配皿5の回転中に発生する振動により、分配中に散薬がR形状の窪み部最下点5bの同心円上からそれて蛇行や偏心して分配されたり、または、円周上の一部分に散薬が集中してくる現象が発生し、分割精度に直接影響する。   The support of the R distribution tray 5 plays an important role in such a device, and if there is a problem with the means of rotation support, the powder generated during the distribution becomes R-shaped by the vibration generated during the rotation of the R distribution tray 5. This causes a phenomenon that the powder is distributed in a meandering or eccentric manner from the concentric circle at the lowest point 5b of the depression, or the powder concentrates on a part of the circumference, which directly affects the division accuracy.

この回転支持に関する問題を解決する技術として、R分配皿5の回転中心軸で支持することで容易に解決する事ができるが、本発明のようにR分配皿5の回転中心軸方向に散薬を掻き出す場合は、少なくともR分配皿5の内周側縁5aより外側でR分配皿5の回転支持を行う制約を受けることになり、R分配皿5の内周側縁5aより外側でR分配皿5の回転支持を行う場合、R形状の窪み部最下点5bと回転支持手段の関係からR分配皿5の回転軸の同心度を組み立て時に調整するのが困難となる上、支持リング6をR分配皿5の回転軸から外周方向に離反させればさせるほど、R分配皿5の回転軸の同心度を組み立て時に調整する難易度が高くなる関係がある。   As a technique for solving the problem related to the rotation support, it can be easily solved by supporting it with the rotation center axis of the R distribution tray 5, but as in the present invention, the powder is applied in the direction of the rotation center axis of the R distribution tray 5. In the case of scraping, the R distribution tray 5 is restricted to support rotation at least outside the inner peripheral edge 5a of the R distribution tray 5, and the R distribution tray is disposed outside the inner peripheral edge 5a of the R distribution tray 5. When the rotation support of 5 is performed, it becomes difficult to adjust the concentricity of the rotation shaft of the R distribution tray 5 at the time of assembly due to the relationship between the lowest point 5b of the R-shaped depression and the rotation support means, and the support ring 6 is There is a relationship in which the difficulty of adjusting the concentricity of the rotation shaft of the R distribution tray 5 during assembly increases as the distance from the rotation shaft of the R distribution tray 5 increases.

また、従来、R分配皿5を1分間に30回転で回転させる場合では、R分配皿5の回転支持部をある程度、回転軸から外周方向に離反させて支持する事も可能である。しかし、1分間に60回転で回転させる本発明の場合、R分配皿5をプレス加工する精度や形状が厳しく求めなければならず、支持構造についても周速度が早い位置をローラ17などで支持するなど条件があり、さらにはこのローラ17の配置を工夫しなければ飛散する散薬が支持リング6とローラ17間に噛み込み、従来では考えられなかった騒音を発生させる条件を含んでいる。(従来は、R分配皿5の支持構造では、散薬分配皿の落下位置より内側で回転速度が低速であり、ローラの配置にそれほど気にしなくても飛散する散薬が支持リングとローラ間に噛み込む問題も発生しない。)   Conventionally, when the R distribution tray 5 is rotated at 30 rotations per minute, the rotation support portion of the R distribution tray 5 can be supported by being separated from the rotation shaft to the outer circumference to some extent. However, in the case of the present invention rotating at 60 revolutions per minute, the accuracy and shape of pressing the R distribution tray 5 must be strictly determined, and the support structure is supported by a roller 17 or the like at a high peripheral speed. In addition, there is a condition in which powdered powder scattered between the support ring 6 and the roller 17 is generated unless the arrangement of the roller 17 is devised, and noise that has not been considered in the past is generated. (Conventionally, in the support structure of the R distribution tray 5, the rotational speed is low inside the position where the powder distribution tray falls, and the scattered powder is scattered between the support ring and the roller without worrying about the arrangement of the rollers. No problem occurs.)

これらの事から、前記支持リング6とローラ17間に散薬が噛み込むと、R分配皿5を振動させるため、分配中に散薬がR形状の窪み部最下点5bの同心円上からそれて蛇行や偏心して分配されたり、または、円周上の一部分に散薬が集中してくる現象が発生する問題が生じる。本発明では、図7に示すように、支持リング6とローラ17との接触部をR分配皿5の鍔5dの位置より下方で、鍔5dの外周径の略内側径方向に、内周側縁5aより外側径の位置とすることで、分配中の散薬が飛散した時に、支持リング6とローラ17との接触部に噛み込む事はない。   For these reasons, when powder powder is caught between the support ring 6 and the roller 17, the R distribution tray 5 is vibrated, so that the powder powder meanders from the concentric circle at the lowest point 5b of the R-shaped depression during distribution. There arises a problem that a phenomenon occurs in which the powder is distributed eccentrically or the powder concentrates on a part of the circumference. In the present invention, as shown in FIG. 7, the contact portion between the support ring 6 and the roller 17 is located below the position of the flange 5d of the R distribution tray 5 and in the substantially inner radial direction of the outer diameter of the flange 5d. By setting the position of the outer diameter from the edge 5a, when the powder being dispensed is scattered, it does not bite into the contact portion between the support ring 6 and the roller 17.

また、支持リング6のローラ17との接触部をR分配皿5の鍔5dの位置より下方で、鍔5dの外周径の略外側径方向の位置とする場合、R分配皿5から遠心力などの条件で、飛散する散薬の飛来放物範囲の内側に設ける場合、極まれに支持リング6とローラ17との接触部に散薬が噛み込む事があるがそれほどの問題とはならず、このような場合でも、支持リング6のローラ17との接触部を図6に示すようなブラシ等で挟まって支持リング6に張りついている散薬を除去すれば連続的な振動を発生させることはできる。   In addition, when the contact portion of the support ring 6 with the roller 17 is positioned below the position of the flange 5d of the R distribution tray 5 and in a position substantially in the outer radial direction of the outer diameter of the flange 5d, centrifugal force or the like is applied from the R distribution tray 5. In the above condition, when the powder is scattered, the powder may be caught in the contact part between the support ring 6 and the roller 17, but this is not a problem. Even in this case, continuous vibration can be generated by removing the powder stuck to the support ring 6 by sandwiching the contact portion of the support ring 6 with the roller 17 with a brush or the like as shown in FIG.

しかし、支持リング6のローラ17との接触部をR分配皿5の鍔5dの位置より同じか上方で、鍔5dの外周径の略外側径方向の位置とする場合や、R分配皿5から遠心力などの条件で、飛散する散薬の飛来放物範囲の外側に設ける場合は、支持リング6とローラ17との接触部に散薬が噛み込む事が頻繁に発生するようになるため、たとえ、支持リング6とローラ17との接触部を図6に示すようなブラシ部材36等で挟まって支持リング6に張りついている散薬を除去しても、短時間に除去できないで張り付く散薬が溜まり、連続的な振動が発生するようになるため好ましくない。   However, when the contact portion of the support ring 6 with the roller 17 is the same or above the position of the ridge 5d of the R distribution tray 5 and the position of the outer peripheral diameter of the ridge 5d is substantially the outer radial direction, When it is provided outside the flying paraboloid range of the scattered powder under conditions such as centrifugal force, the powder will frequently bite into the contact portion between the support ring 6 and the roller 17. Even if the powder adhering to the support ring 6 is removed by sandwiching the contact portion between the support ring 6 and the roller 17 with a brush member 36 or the like as shown in FIG. 6, the adhering powder accumulates without being removed in a short time. This is not preferable because a general vibration is generated.

図11の(a)(b)(c)は支持リング6とローラ17の支持形態を示す図である。   FIGS. 11A, 11B, and 11C are views showing a support form of the support ring 6 and the roller 17. FIG.

図11の(a)の支持リング6とローラ17の支持形態は、支持リング6の内径側を外周方向の下方に向かって押しつけるローラ17と、支持リング6が搭載されるローラ17とにより、2方向から支持するようになっており、R分配皿5の裏面側に支持リング6とローラ17が配置されている。   The support form of the support ring 6 and the roller 17 in FIG. 11A is 2 by the roller 17 that presses the inner diameter side of the support ring 6 downward in the outer peripheral direction and the roller 17 on which the support ring 6 is mounted. The support ring 6 and the roller 17 are arranged on the back surface side of the R distribution tray 5.

図11の(b)の支持リング6とローラ17の支持形態は、支持リング6の外径側を内周方向の下方に向かって押しつけるローラ17と、支持リング6が搭載されるローラ17とにより、2方向から支持するようになっており、R分配皿5の外周部に備えた鍔5dの更に外側から上方に向かって支持リングから延びる支持リングガイド6aを備えている。   The support form of the support ring 6 and the roller 17 shown in FIG. 11B includes a roller 17 that presses the outer diameter side of the support ring 6 downward in the inner circumferential direction, and a roller 17 on which the support ring 6 is mounted. The support ring guide 6a extends from the support ring from the outer side to the upper side of the flange 5d provided on the outer peripheral portion of the R distribution tray 5 and is supported from two directions.

このため、R分配皿5の表面から飛散する散薬は、前記支持リングガイド6aによりR分配皿5の外周側に飛散する事が極力少なくなり、偶然にも支持リング6とローラ17の間に散薬が挟まることはほとんど発生しない。   For this reason, the powder scattered from the surface of the R distribution tray 5 is less likely to be scattered on the outer peripheral side of the R distribution tray 5 by the support ring guide 6a. Almost never occurs.

ここで、支持リングガイド6aの形状は上方に向かって延びる支持リングとしたが、ローラ17の上方に被さるように外周方向へ延びる支持リングガイド6aとしてもよく、支持リングガイド6aの代わりに、R分配皿5の外周部に備えた鍔5dによって、ローラ17の上方に被さるようにしてもよい。   Here, the shape of the support ring guide 6a is a support ring that extends upward. However, the support ring guide 6a may be a support ring guide 6a that extends in the outer peripheral direction so as to cover the roller 17, and instead of the support ring guide 6a, R You may make it cover the roller 17 with the ridge 5d with which the outer peripheral part of the distribution tray 5 was equipped.

図11の(c)の支持リング6とローラ17の支持形態は、支持リング6の外径側を内周方向の下方に向かって押しつけるローラ17と、支持リング6が搭載されるローラ17とにより、2方向から支持するようになっており、R分配皿5の外周部に備えた鍔5dの裏面に、鍔5dと支持リング6の間に間隙を設け、この間隙を起点としてローラ17の上方に被さるように設けられたカバー部材18によって、ローラ17が支持リング6に接触しない周囲を覆っている。   The support form of the support ring 6 and the roller 17 shown in FIG. 11C includes a roller 17 that presses the outer diameter side of the support ring 6 downward in the inner circumferential direction, and a roller 17 on which the support ring 6 is mounted. A support is provided from two directions, and a gap is provided between the flange 5d and the support ring 6 on the back surface of the flange 5d provided on the outer periphery of the R distribution tray 5. The periphery of the roller 17 that does not come into contact with the support ring 6 is covered by a cover member 18 provided so as to cover the cover ring 18.

このように、カバー部材18によってローラ17が覆われているため、偶然にも支持リング6とローラ17の間に散薬が挟まることはほとんど発生しない。   As described above, since the roller 17 is covered with the cover member 18, the powdered powder hardly occurs between the support ring 6 and the roller 17 by chance.

また、ローラ17の当たり面は、樹脂などの材料により、振動を吸収できる柔らかい材質を前記支持リングに固着しても良く、逆に、ローラ17の表面材質を樹脂、またはゴム係の材質を用いることで、R分配皿5の高速化に対応する事が可能となる。   The contact surface of the roller 17 may be a soft material that can absorb vibrations, such as a resin, and may be fixed to the support ring. Conversely, the surface material of the roller 17 is a resin or a rubber-related material. Thus, it is possible to cope with the increase in the speed of the R distribution tray 5.

更に、ローラ17は、可能な限り、直径の大きいものを採用すれば、ローラ17の回転速度が下がり、耐久性や騒音、振動を押さえることが可能になる。   Further, if a roller 17 having a diameter as large as possible is adopted, the rotation speed of the roller 17 is lowered, and durability, noise, and vibration can be suppressed.

なお、ここで開示した図11の(a)(b)(c)は実施に当たり示した手段であって、散薬分配皿の回転支持リングと前記回転支持リングに接触するローラの接触部分に、R分配皿の遠心力により飛散した顆粒等の散薬が噛み込まない位置に配置したとは、カバーで覆う等のあらゆる手段が発明の趣旨に含まれている。   11 (a), 11 (b), and 11 (c) disclosed herein are the means shown in the implementation, and the rotation support ring of the powder distribution tray and the contact portion of the roller that contacts the rotation support ring are R All means such as covering with a cover is included in the gist of the invention that the powder or the like scattered by the centrifugal force of the distribution dish is disposed at a position where it is not bitten.

図12は、R分配皿5の取り付けについての形態が違う形式を示すものである。   FIG. 12 shows a form in which the form for attaching the R distribution tray 5 is different.

ここで上げるR分配皿5の鍔5dには、支持リング6と締め付けるネジ穴を持たない形態であり、R分配皿5の鍔5dは水平ラインより下方向に環状に折り曲げられている。   The eaves 5d of the R distribution tray 5 raised here does not have a screw hole for tightening with the support ring 6, and the eaves 5d of the R distribution tray 5 are bent in an annular shape downward from the horizontal line.

このように鍔5dを下方に曲げることにより、曲げ角度が水平方向から垂直方向に曲げ角度がきつくなるに従い、R分配皿5の曲げ強度が向上するが、反面支持リング6に取り付ける構造に難点が生じる。   By bending the flange 5d downward as described above, the bending strength of the R distribution tray 5 improves as the bending angle becomes tighter from the horizontal direction to the vertical direction. However, the structure attached to the support ring 6 has difficulties. Arise.

しかし、図12のように支持リング6と鍔5dを接触させ、締め付けネジ19を皿ネジまたは支持リング6と鍔5dの勾配傾斜を備えた止め具を締め付けネジ19で締め付ける事でその問題を解決している。   However, as shown in FIG. 12, the support ring 6 and the flange 5d are brought into contact with each other, and the problem is solved by tightening the tightening screw 19 with a countersunk screw or a stopper having a gradient inclination between the support ring 6 and the flange 5d with the tightening screw 19. is doing.
