本発明は、 錠剤、 小型の電子部品あるいは食品などの 粒体を、 例えば製造装置から集荷場所まで搬送するため の搬送装置に関する。 背景技術  The present invention relates to a transport device for transporting granules such as tablets, small electronic components or food, for example, from a manufacturing device to a collection location. Background art
従来、 粉末を圧縮する粉末圧縮成形機により成形され る例えば錠剤は、 一旦集荷容器に集荷され、 検査や分包 などのために検査器や分包装置まで搬送される。 搬送に あっては、 人手に頼ることなく、 振動フィーダ、 ベルト コンベア、 あるいは圧送装置などの搬送装置により 自動 化されている。 具体的には、 例えば特許文献 1 (特開 2 0 0 2 — 4 6 8 4 2号公報） に示されるように、 集荷さ れた錠剤を搬送装置に連結されるホツバに投入し、 ホッ パから排出される錠剤を、 例えば搬送装置である振動フ ィーダにより検査器まで搬送するものである。  Conventionally, for example, tablets formed by a powder compression molding machine that compresses powder are once collected in a collection container and transported to an inspection device or a packaging device for inspection or packaging. The transfer is automated by a transfer device such as a vibrating feeder, belt conveyor, or pressure feeder without relying on humans. More specifically, for example, as shown in Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-46864), the collected tablets are put into a hopper connected to a transport device, and the hopper is placed in the hopper. The tablets discharged from the device are conveyed to the inspection device by, for example, a vibration feeder that is a conveying device.
しかしながら、 振動フィーダにあっては、 錠剤'を搬送 している間、 錠剤の搬送路である 卜ラフが振動している ので、 その振動による騒音及び錠剤がトラフに衝突して 発生する騒音がかなり高くなつた。  However, in the case of a vibrating feeder, while the tablets are being transported, the trough, which is the transport path of the tablets, vibrates, and the noise due to the vibrations and the noise generated when the tablets collide with the trough are considerable. Got high.
また、 振動フィーダは、 トラフを振動させるために駆 動コア、 固定 ァ、 電磁コィル及び電磁石といつ 7こ霄 の大きな部品を必要とする。 このため、 装置自体の胃 が重くなり、 安定性を確保しよう とすると 大型になつ た。 それゆえ 比較的高所への取付が困難であつ 7こ 加えて、 卜ラフ .を長尺のものにすると、 里の増加を 招く と と もに ラフの固有振動数と共振する可能性が あり、 良好な振動が阻害されるおそれがある このためThe vibratory feeder is also used to vibrate the trough. It requires a moving core, a fixed coil, an electromagnetic coil, an electromagnet, and a large number of parts. As a result, the stomach of the device itself became heavy, and it became large in order to ensure stability. Therefore, it is relatively difficult to mount it at a high place.7 In addition, if the trough is made long, it may cause an increase in villages and resonate with the natural frequency of the luff. , Good vibration may be hindered.
、 錠剤を長距離搬送するためには、 複数の振動フィーダ を連結する必要があり、 製造コス トが上昇した In order to transport tablets over long distances, it is necessary to connect multiple vibrating feeders, leading to increased manufacturing costs
その上、 振動により錠剤を搬送するので 搬送速度が 低い。 搬送速度を早く しょう とすると、 振動数を上げる 必要があるが 振動数を上げると錠剤と トラフとの衝突 回数が増加し 錠剤が損傷するおそれが生じる のた め、 搬送能力を高くするこ とが難しかった  In addition, tablets are transported by vibration, so the transport speed is low. To increase the transport speed, it is necessary to increase the frequency.However, increasing the frequency increases the number of collisions between the tablets and the trough, which may damage the tablets. was difficult
さ らにまた 卜ラフを上がり勾配に設定すると、 錠剤 が自重で搬送方向とは逆に移動することがある。 このた め、 卜ラフは ほぼ水平に設置するか、 あるいはわずか な下がり勾配に設置しないと、 搬送能力が低下した。 そ れゆえ、 設置する際の自由度が低かった。 発明の開示  Furthermore, if the trough is set to an upward slope, the tablet may move by its own weight in the direction opposite to the transport direction. For this reason, unless the trough was installed almost horizontally or at a slight downward slope, the transport capacity was reduced. Therefore, the degree of freedom in installation was low.

They are formed at predetermined intervals. Specifically, as shown in FIGS. 5 and 6, each opening 21a is formed in a substantially semicircular shape by, for example, press working, and each guide wall 21b is formed with an opening 21a. The opening 21a is formed almost simultaneously with the formation of the opening 21a by a part of the flat plate 21 located at the opening position at the opening a.

All the openings P 2 1a are aligned in the same direction and are arranged in a matrix.Especially, the openings 21a are arranged at predetermined intervals to form one row. Each row is arranged in the width direction of the flat plate 21 at an interval different from the above-specified interval, and for the adjacent row, each opening 21a is formed at a half interval of the flat plate 21. They are arranged so as to be shifted along the longitudinal direction. The distance between the centers of the openings 21a is set such that the particles τb always come into contact with the airflow ejected from at least one of the adjacent openings P21a. With this setting, no matter what direction the particle Tb faces, the air ejected from the opening 21a urges the particle Tb in the discharge P13a direction, As it realizes smooth transportation
案内壁 2 1 bは、 第 6 図に示すように 平板 2 1 の長 手方向に沿つた断面形状を緩やかに傾斜する曲線形状と している。 すなわち、 案内壁 2 1 bは、 開口 2 1 a との 関係で ¾1口 2 1 a の直線部分 2 1 a bに対応する案内 壁 2 1 bの自由端 2 1 b a側において平板 2 1 の下面か ら所定距離下側に離れており、 その自由端 2 1 から 開口 2 1 a の曲線部分 2 1 a aに連続する うにせり上 がる曲面構造である。 したがつて 平板 2 1 の下面に沿 つて移動する空気は、 案内壁 2 1 b a とへ盤 2 1 の下面 との間隙から進入し、 案内壁 2 1 b aに案内されて開口 As shown in FIG. 6, the guide wall 21b has a cross-sectional shape along the longitudinal direction of the flat plate 21 having a curved shape that is gently inclined. That is, the guide wall 21b is connected to the opening 21a by the lower end of the flat plate 21 at the free end 21ba side of the guide wall 21b corresponding to the linear portion 21ab of the opening 21a. A curved surface structure that is separated from the free end 21 by a predetermined distance from the free end 21 and continues to the curved portion 21 aa of the opening 21 a. Therefore, the air moving along the lower surface of the flat plate 21 enters through the gap between the guide wall 21 ba and the lower surface of the slab 21 and is guided by the guide wall 21 ba to open.

Practically, it should be set based on the required transport capacity, with a size sufficient to allow a large number of fluids Tb to roll on the upper surface of the airflow forming body 2 in a practical manner.

この実施例にあつては、 送風と吸気とを行う送風機 B wが搬送装置 F dに接 Sれる のである 。 すなわち 図 7 に示すように、 送風機 B wは 、 上下に二空間に分割 された Λウジング B w 1 と、 そのノ、ゥジング B w 1 の上 側の空間に取り付けられて搬送される粒体 T bに付着し ていた微粉末を する集塵手段 (サイクロン及びフィ ル夕） B w 2 と 、 その八ゥジング B w 1 の下側の空間に 取り付けられるファン付モー夕 Β w 3 とを備え、 集 手 段 B w 2 を通過した空気が上側の空間カゝら下側の空間に 行く ように上下の空間は連通しており、 フアンを回転さ せることにより送風を行う とともに、 吸気を行う。  In this embodiment, a blower Bw for blowing and suctioning air is brought into contact with the transfer device Fd. That is, as shown in FIG. 7, the blower Bw is composed of a housing Bw1 divided into two spaces vertically and a granule T attached and transported in the space above the housing Bw1. a dust collecting means (cyclone and filter) Bw2 for collecting fine powder adhering to b, and a fan-equipped motor w3 mounted in a space below the housing Bw1; The upper and lower spaces are connected so that the air that has passed through the collecting means Bw2 goes from the upper space to the lower space, and air is blown and air is taken in by rotating the fan.

Ρ 1 is connected, and the dust collecting means に placed on the back side of the fan 吸 気
B W 5 に排気管路 P 2 を接続する とで 流形成体 2 の平板 2 1 より下の空間に空気を送り、 円筒 1 1 の上側 の内壁近傍の 気を排出 (吸気 ) する ο このように、 送 風管路 P 1 と排気管路 P 2 とを送風機 Β Wに接続するこ とにより、 送風機 B wから見た場合に、 送風管路 P 1 搬送装置 F d 排 管路 Ρ 2 によりほぼ閉じた管路が形 成され、 その内部で空気が循環するものである 0 なお、 第 4図及び第 7 図において、 矢印 Kは、 空気の移動方向 を示す。 When the exhaust pipe P 2 is connected to the BW 5, the air is sent to the space below the flat plate 21 of the flow forming body 2, and the air near the inner wall above the cylinder 11 is exhausted (intake). By connecting the blower pipe P1 and the exhaust pipe P2 to the blower ΒW, when viewed from the blower Bw, the blower pipe P1 and the transfer device Fd are almost equal to the discharge pipe Ρ2. A closed pipeline is formed and air circulates inside it. In FIGS. 4 and 7, arrow K indicates the direction of air movement.
搬送装置 F dは、 その円筒アセンブリ 1 の軸線をほぼ 水平状態に維持されて設置される。 そして、 管路接続部 材 1 6 の給気接続部 1 6 dと送風機 B wの吐出口 B w 4 とが送風管路 P 1 によ り接続されて、 給気空間 1 6 aを 介して円筒 1 1 に空気が供給されるとともに、 排気接続 部 1 6 e と送風機 B wの吸気口 B w 5 とが排気管路 P 2 により接続されて、 排気空間 1 6 bを介して円筒 1 1 の 空気が排出される。 空気は、 円筒 1 1 の気流形成体 2 の 平板 2 1 の下側の空間に充満して加圧され、 気流形成体 2 の整流部 2 9、 具体的には平板 2 1 のそれぞれの開口 2 1 aから噴出する。 この場合に、 整流部 2 9は開口 2 1 a と案内壁 2 1 b とを有しているので、 空気は案内壁 2 1 bに案内されて開口 2 1 aに導かれる。 案内壁 2 1 bは、 排出口 1 3 aに向かってせり上がるように形成さ れているので、 第 6図に矢印 Mで示すように、 空気は開 口 2 1 aから排出口 1 3 a方向に向かって斜め上側に噴 出する。 このようにそれぞれの開口 2 1 aから空気が排 出口 1 3 a方向でかつ上方向に噴出するので、 気流形成 体 2 の平板 2 1上面近傍には気流形成体 2の全域にわた つて排出口 1 3 aに向かう正圧の気流が形成される。  The transfer device Fd is installed with the axis of the cylindrical assembly 1 kept substantially horizontal. Then, the air supply connection part 16 d of the pipe connection member 16 and the discharge port B w 4 of the blower B w are connected by the blow pipe P 1, and are connected through the air supply space 16 a. Air is supplied to the cylinder 11 and the exhaust connection part 16 e and the intake port B w 5 of the blower B w are connected by the exhaust pipe P 2, and the cylinder 1 1 is connected via the exhaust space 16 b. Of air is exhausted. The air fills the space below the flat plate 2 1 of the air flow forming body 2 of the cylinder 1 1 and is pressurized, and the rectifying portion 29 of the air flow forming body 2, specifically, the opening 2 of the flat plate 2 1 Squirt from 1 a. In this case, since the flow straightening portion 29 has the opening 21a and the guide wall 21b, the air is guided by the guide wall 21b and is guided to the opening 21a. Since the guide wall 21b is formed so as to rise toward the outlet 13a, air flows from the opening 21a to the outlet 13a as shown by an arrow M in FIG. Spouts diagonally upward in the direction. As described above, since air is ejected from the respective openings 21a in the direction of the discharge outlets 13a and upward, the outlets are provided in the vicinity of the upper surface of the flat plate 21 of the airflow forming member 2 over the entire area of the airflow forming member 2. A positive pressure airflow towards 13a is formed.
この一方で、 排気開口部材 1 4の排気口 1 4 a、 排気 管 1 5及ぴ管路接続部材 1 6 を介して、 搬送空間 の 上部の空気が送風機 B wにより吸引され、 搬送空間 S p には気流形成体 2 の平板 2 1から最も遠い気流形成体 2 の上側領域言い換えれば円筒 1 1 の上壁の直下には、 負 圧の領域が形成される。 この負圧の領域は、 排出口 1 3 aから外気が吸入され、 円筒 1 1 に設けた排気開口 1 1 aから円筒 1 1 内の空気が吸引されることで形成される 。 このように、 搬送空間 S pの内部に負圧の領域を形成 する ことにより、 開口 2 l aから噴出する空気を噴出し 易くするものである。 この結果、 気流形成体 2 の平板 2 1 と一対の縦壁 2 2 と円筒 1 1 とで形成される搬送空間 S p には、 平板 2 1 の幅寸法とほぼ等しい幅寸法の斜め 上向きの空気の流れが確実に形成される。 なお、 吸引さ れる空気の流量は、 空気の流量より多く設定するのが好 ましい。 このように吸引空気の流量を供給される空気の 流量より多くすることにより、 負圧を形成しやすくする ものである。 On the other hand, the upper air in the transport space is sucked by the blower Bw through the exhaust port 14 a of the exhaust opening member 14, the exhaust pipe 15 and the pipe connection member 16, and the transport space Sp In the upper part of the airflow forming member 2 farthest from the flat plate 21 of the airflow forming member 2, in other words, a region of negative pressure is formed immediately below the upper wall of the cylinder 11. This negative pressure region is formed by sucking outside air from the outlet 13 a and sucking air in the cylinder 11 from the exhaust opening 11 a provided in the cylinder 11. By forming a negative pressure area inside the transfer space Sp in this way, it is easy to blow out the air that blows out from the opening 2 la. As a result, the conveying space Sp formed by the flat plate 21 of the airflow forming body 2, the pair of vertical walls 22, and the cylinder 11 1 has an obliquely upward air having a width substantially equal to the width of the flat plate 21. Is reliably formed. It is preferable that the flow rate of the sucked air be set higher than the flow rate of the air. By making the flow rate of the suction air larger than the flow rate of the supplied air, a negative pressure can be easily formed.
以上のようにして搬送空間 S p内に気流が形成されて いる状能、で 、 投入口 1 2 aから粒体 (錠剤） T bを投入 すると 、 投入口 1 2 aは平板 2 1 の上方の空間つまり搬 送空間 S Pに連通しているので、 投入された粒体 T bは 平板 2 1 の上面に落下して開 P 2 1 aから噴出する加圧 された により排出口 1 3 a方向に付勢される。 しか も、 開 P 2 1 aからの加圧された空 による気流は、 排 出口 1 3 aに向かつて流れているので 、 投入された粒体 When the airflow is formed in the transport space Sp as described above, when the particles (tablets) Tb are charged from the input port 12a, the input port 12a is located above the flat plate 21. Since the charged particles Tb fall on the upper surface of the flat plate 21 and are ejected from the open P21a, the discharged particles 13b are in the direction of the discharge port 13a because they are communicated with the space, that is, the transport space SP. It is urged to. Furthermore, since the air flow due to the pressurized air from the opening P21a flows toward the discharge outlet 13a, the injected granules
T bは 流に沿つて排出口 1 3 aに向かって搬送される 。 この間 、 整流部 2 9 の開口 2 1 aが上述のように配列 されているので、 隣接の 口 2 1 a間において粒体 T b が停止することはほぼない 。 つまり、 粒体 T bは、 気流 形成体 2の平板 2 1 の表面をほぼ一定な速度で転がってTb is conveyed along the stream towards outlet 13a. During this time, the openings 21 a of the rectifying section 29 are arranged as described above. Therefore, the particles Tb hardly stop between the adjacent mouths 21a. That is, the granular material T b rolls on the surface of the flat plate 21 of the airflow forming body 2 at a substantially constant speed.
、 排出口 1 3 aまで達するものである。 さ らに 、 縦壁 2The outlet reaches up to 13a. In addition, vertical wall 2
2が平板 2 1 の両側縁近傍に設けられているため、 それ ぞれの開口 2 1 aから噴出する空気が平板 2 1 の両側に 逸れることがない。 これにより、 気流が搬送空間 S p を 投入口 1 2 aから排出口 1 3 aに向かつて ほぼ一様に 流れるものである。 したがつて、 粒体 T bは 各開口 22 is provided near both side edges of the flat plate 21, so that the air ejected from the respective openings 21 a does not deviate to both sides of the flat plate 21. Thus, the airflow flows almost uniformly from the inlet 12a to the outlet 13a in the transport space Sp. Therefore, the granular material T b has 2
1 aから噴出する空気により搬送中に勢いがついている ので、 順次排出口 1 3 aから排出される o Since the air ejected from 1a is gaining momentum during transport, it is sequentially discharged from the outlet 13a o
このように、 粒体 T bは開口 2 1 aから噴出する空気 により排出口 1 3 a方向に付勢されるので 投入口 1 2 a側に戻ることなく搬送される。 このため 円筒 1 1が 流体 T bの搬送方向に対して上り勾配に設置されても、 流体 T bを確実に投入口 1 2 a力 ら排出 Π 1 3 aまで搬 送することができる。 また 、 粒体 T b を気流により平板 As described above, the granular material Tb is urged in the direction of the outlet 13a by the air ejected from the opening 21a, and is conveyed without returning to the inlet 12a. For this reason, even if the cylinder 11 is installed at an upward slope with respect to the transport direction of the fluid Tb, the fluid Tb can be transported from the inlet 12a to the outlet 排出 13a without fail. Also, the granular material T b is flattened by airflow.
2 1 の上面を転がすので、 粒体 T b表面に付着している 原料粉末を 送中に粒体 T bから取り除 < とができ る。 しかも 、 取り除かれた原料粉末は、 搬送空間 S p内 に飛散した後、 円筒 1 1上壁近傍を流れる 圧の気流に 吸収され、 排気開ロ部材 1 4を介して円筒ァセンプリ 1 内から排出されるつまり送風機 B wの集塵手段 B w 2 に より集塵されるので、 原料粉末が搬送装置 F dの設置さ れた空間内に飛散することを確実に防止する とができ その上 この搬送装置 F dには粒体 T bを搬送させる ために振動したり回転したりする部分がないので その ような構成要素から発する騒音がなく lk を改 する とができる。 また、 粒体 T bを搬送させる構成に 上述のよつな可動機械部分が存在しないので、 長距離の 搬送においても短距離の搬送と同じ能力で実現させる とがでさる 。 したが て、 例えば、 錠剤の製造室と錠剤 の集荷 所が別室あるいは別棟などで距離があつても 容易に 剤を搬送することがでさる。 Since the upper surface of 21 is rolled, the raw material powder adhering to the surface of the granular material Tb can be removed from the granular material Tb during feeding. Moreover, the removed raw material powder is scattered into the transfer space Sp, is absorbed by the airflow of the pressure flowing near the upper wall of the cylinder 11, and is discharged from the cylindrical assembly 1 through the exhaust opening member 14. That is, since the dust is collected by the dust collecting means Bw2 of the blower Bw, it is possible to reliably prevent the raw material powder from scattering into the space where the transport device Fd is installed. In addition, since the transport device Fd has no portion that vibrates or rotates to transport the granular material Tb, lk can be improved without noise generated from such components. Further, since there is no movable mechanical part as described above in the configuration for transporting the granular material Tb, it is possible to achieve the same capability even in the long-distance transport as in the short-distance transport. Therefore, for example, even if the tablet manufacturing room and the tablet collection site are separated in a separate room or a separate building, the drug can be easily transported.
なお 、 本発明は 、 上記実施の形態に限定されるもので はない  Note that the present invention is not limited to the above embodiment.
上記実施例にあ ては、 管体として円筒 1 1 を説明し たが 管体 T uは 第 8 図に示すよう に、 その断面が正 方形 (同図において実線にて示す） あるいは長方形 （同 図において破線にて示す） などの四角形のものであって あよい あるいは 気流形成体 1 0 2 よ り上側の空間と 下側の空間との断面形状が異なるものであつてもよい。 このような管体 T U としては、 例えば 、 第 9 図の （ a ) 及び ( b ) に示すよう に、 上側の空間の断面形状が四角 形で 下側の空間の断面形状がほぼ半円 （同図の （ a ) に実線で示す） あるいは一部を直線で切り欠いた円弧 （ 同図の ( a ) に破線で示す） のもの 台形のものとなる 管体である 。 このような管体 T uは 上側と下側とが個 別に作られ 、 その 一体にして管状をなすものであって い。 な 管体 T u以外の構成については 次に説明 する ^流形成体 1 0 2 を除いて上記実施例と 1口 ίじであつ てよい。 In the above embodiment, the cylinder 11 was described as the tube, but as shown in FIG. 8, the tube Tu has a square cross section (indicated by a solid line in FIG. 8) or a rectangle (in FIG. It may be a square shape (shown by a broken line in the figure), or the cross-sectional shape of the space above and below the airflow forming body 102 may be different. As such a tubular body TU, for example, as shown in (a) and (b) of FIG. 9, the cross-sectional shape of the upper space is a quadrangle, and the cross-sectional shape of the lower space is substantially a semicircle (same as in FIG. 9). This is a trapezoidal tube with an arc (shown by a solid line in (a) of the figure) or an arc partially cut off by a straight line (shown by a dashed line in (a) of the figure). The upper and lower sides of such a tubular body Tu are individually made, and are integrally formed into a tubular shape. No. The configuration other than the tubular body Tu will be described below. The structure may be the same as that of the above embodiment except for the flow forming body 102.
すなわち 気流形成体 1 0 2 の上側の空間の断面形状 が四角形の場合 気流形成体 1 0 2 は 上 3Dの実施例と は異なり 平板 2 1 と気密部材 2 3 とで構成され、 縦壁 That is, when the cross-sectional shape of the space above the airflow forming member 102 is square, the airflow forming member 102 is different from the upper 3D embodiment, and is composed of the flat plate 21 and the airtight member 23,
2 2 を備えないちのでめる 。 平板 2 1 は上記実施例と同 じに 、 複数の開 P 2 1 a とそれぞれの 1开 J P 2 1 a の下側 に設けられる案内 2 1 b とを備えるちのでめる 0 平板 1 2 1 の両側縁にその全長に亘って取 付けられる気密 部材 2 3 は 平板 1 2 1 と管体 T u との間に間隙が生じ るのを防ぐためのちのである o のよ な気密部材 2 3 は 上 実施例においても採用するものであつてよい o したがつて 、 気流形成体 1 0 2 の上側の空間の断面形 状が四角形であれば、 平板 2 1 の幅方向に気流が存在し ない空間が形成されることをなくすことができる。 つま り 縦壁 2 2がなく とも 管体 T uの内壁が平板 2 1 の ほぼ両側縁に存在するため 複数の開口 2 1 aにより形 成された気流が気流形成体 1 0 2 の平板 2 1 の全幅にお いてほぼ均等に形成される 0 この結果、 気流形成体 1 02 Do not have 2. The flat plate 21 is provided with a plurality of openings P 21 a and guides 21 b provided below the respective JP 21 a in the same manner as in the above embodiment. The airtight members 23 attached to the both side edges over the entire length thereof are to prevent a gap from being formed between the flat plate 121 and the tube Tu. Therefore, if the cross-sectional shape of the space above the airflow forming body 102 is rectangular, the airflow does not exist in the width direction of the flat plate 21. Can be prevented from being formed. That is, since the inner wall of the tube Tu is present on almost both side edges of the flat plate 21 even without the vertical wall 2 2, the airflow formed by the plurality of openings 21 a is formed by the flat plate 2 1 of the airflow forming member 102. 0 is formed almost evenly over the entire width of the air flow.

Q In the embodiment, the pipe assembly U 1 having the exhaust opening P member 14 has been described, but the exhaust opening 11 a is not provided with the exhaust opening 11 B w intake Can be directly connected to PB w 2
同様にして、 投入口 1 2 aから排気するものであれば 排気開口部材 1 4、 排気開口 1 1 a及び管路接 部材 Similarly, if air is exhausted from the inlet 12a, the exhaust opening member 14, the exhaust opening 11a, and the pipe connection member
1 6 は不要である。 具体的には、 第 1 1 図に示すように 管体ァセンブリ 1 0 1 は、 管体 T uである円筒 1 1 1 が 、 その一方の端部に投入口 1 1 2 aを備 るとともに 投入口 1 1 2 aの下側に気体供給 Π 1 1 2 bを備えて いる。 のように排気開口部材及び管路接続部材を備え ていないので、 円筒 1 1 1 の排出口 1 1 3 a の近傍の上 壁に排気開口を備えていない。 そして上記実施形態のよ に、 円筒 1 1 1 内に気流形成体 1 0 2が取り付けてあ り 、 気体供給口 1 1 2 aから空気が ¾流形成体 1 0 2 の 下側空間に供給さ る 16 is unnecessary. More specifically, as shown in FIG. 11, the tubular assembly 101 is configured such that a cylinder Tu, which is a tubular Tu, is provided with an input port 112a at one end thereof. A gas supply Π 1 1 2b is provided below the mouth 1 1 2a. Since there is no exhaust opening member and no pipe connection member as shown in Fig. 1, no exhaust opening is provided on the upper wall near the exhaust port 113a of the cylinder 111. Then, as in the above-described embodiment, the airflow forming body 102 is mounted inside the cylinder 111, and air is supplied from the gas supply port 112a to the space below the flow forming body 102.

In other words, the charging port 112a is connected to a rotary powder compression molding machine or the like to receive the supply of the granular material Tb and to communicate with the suction device. Then, when the suction device is operated, the external air flows into the cylinder 1 1 1 from the outlet 1 1 3 a, and the air in the cylinder 1 1 1 is sucked from the input 1 1 2 a by the above-mentioned operation. Similarly to the example, since the area near the upper wall of the cylinder 1 11 has a negative pressure, it is possible to exhibit the same transfer capacity as that of the above embodiment.
