Further, the inner diameter of the tapered portion 104b, the inner diameter of the first flange portion 104a, and the inner diameter of the main body 103 are the same.
気送管構成部材１０２の第二の連結部１０５は、本体１０３の外径より大きい外径の環状の第二のフランジ部１０５ａと、第二のフランジ部１０５ａの内側に形成され第一の連結部１０４のテーパー部１０４ｂと係合する環状の逆テーパー部１０５ｂとから構成されている。逆テーパー部１０５ｂの内径は、第二のフランジ１０５ｂの端部から軸方向内方に向かって（図３（ａ）では左側から右側に向かって）次第に小さくなっており、第一の連結部１０４のテーパー部１０４ｂの外径に対応して形成されている。そして、図３（ｂ）に示すとおり、第一の連結部１０４と第二の連結部１０５とが連結されると、テーパー部１０４ｂと逆テーパー部１０５ｂとが係合するようになっており、これによって気送管１０１の連結部（気送管構成部材１０２同士を連結している部分）の内面側において段差が生じることがない。また、図３（ａ）に示すとおり、第一のフランジ部１０４ａと第二のフランジ部１０５ａとにはボルト１０６を挿入する挿入口１０４ｃ、１０５ｃが少なくとも２ヶ所に形成され、図３（ｂ）に示すとおり、第一のフランジ部１０４ａと第二のフランジ部１０５ａとはボルト１０６とナット１０７とで締結されるのが好ましい。 The second connecting portion 105 of the pneumatic tube constituting member 102 is formed on an annular second flange portion 105 a having an outer diameter larger than the outer diameter of the main body 103 and an inner side of the second flange portion 105 a to perform the first connection.

Is formed corresponding to the outer diameter of the tapered portion 104b. Then, as shown in FIG. 3B, when the first connecting portion 104 and the second connecting portion 105 are connected, the tapered portion 104b and the reverse tapered portion 105b are engaged with each other. As a result, no step is generated on the inner surface side of the connection portion of the air supply pipe 101 (the part connecting the air supply pipe components 102). Further, as shown in FIG. 3A, at least two insertion openings 104c, 105c for inserting bolts 106 are formed in the first flange portion 104a and the second flange portion 105a, respectively, as shown in FIG. 3B. It is preferable that the first flange portion 104 a and the second flange portion 105 a be fastened with a bolt 106 and a nut 107 as shown in FIG.
図２を参照して説明する。気送管１０１には、気送管１０１の内部を減圧するための吸引手段１３０と、気送管１０１に空気を圧送する圧送手段１４０とが連結されている。吸引手段１３０は、吸引ポンプ１３１と、バルブ１３２を備えた吸気管１３３とにより構成され、圧送手段１４０は、圧送ポンプ１４１と、バルブ１４２を備えた圧送管１４３とにより構成される。 This will be described with reference to FIG. Connected to the pneumatic tube 101 are a suction means 130 for decompressing the inside of the pneumatic tube 101 and a pumping means 140 for pumping air to the pneumatic tube 101. The suction means 130 is constituted by a suction pump 131 and an intake pipe 133 provided with a valve 132, and the pressure feeding means 140 is constituted by a pressure feed pump 141 and a pressure feed pipe 143 provided with a valve 142.
送信ステーション１１０は、気送管１０１の一端部側に設けられ、送信テーブル１１４を気送管１０１の該一端部に対して近接（実線で示す。）、離反（２点鎖線で示す。）させるように駆動する昇降手段１１２を備えている。昇降手段１１２は、モータ１１１の回転運動を、昇降手段１１２に内蔵されたボールねじ１１３を介して直線運動に変換して送信テーブル１１４の係合部１１４ａに伝達する構成を備え、送信テーブル１１４を該一端部に対して進退させ、所望の位置に位置付ける機能を有する。送信テーブル１１４には、連通孔１１５が配設され、配管１１６を介して大気開放弁１１７が接続されている。送信テーブル１１４が気送管１０１の一端部に最も近接された状態（実線で示す。）では、送信テーブル１１４が気送管１０１の一端部を閉塞し、特に大気開放弁１１７を閉じた状態では、気送管１０１の一端部側における空気の出入りが制限される。 The transmission station 110 is provided on one end side of the pneumatic tube 101, and brings the transmission table 114 into proximity (indicated by a solid line) to the one end of the pneumatic tube 101 and separates (indicated by a two-dot chain line). Ascending and lowering means 112 is provided. The elevating means 112 is configured to convert the rotational movement of the motor 111 into linear movement via the ball screw 113 incorporated in the elevating means 112 and transmit the linear movement to the engaging portion 114 a of the transmission table 114. It has a function of advancing and retracting to one end and positioning at a desired position. A communication hole 115 is disposed on the transmission table 114, and an air release valve 117 is connected via a pipe 116. In the state where the transmission table 114 is closest to one end of the air pipe 101 (indicated by a solid line), the transmission table 114 blocks the one end of the air pipe 101, and particularly in the state where the air release valve 117 is closed. The movement of air at one end side of the pneumatic tube 101 is restricted.
受信ステーション１２０は、送信ステーション１１０と略同様の構成を備えており、受信テーブル１２４を気送管１０１の他端部に対して近接（実線で示す。）、離反（２点鎖線で示す。）させるように駆動する昇降手段１２２を備えている。昇降手段１２２は、上記した昇降手段１１２と同様の構成からなり、モータ１２１の回転運動を、昇降手段１２２に内蔵された図示しないボールねじを介して直線運動に変換して受信テーブル１２４の図示しない係合部に伝達する構成を備え、受信テーブル１２４を該他端部に対して進退させる機能を有する。受信テーブル１２４には、連通孔１２５が配設され、配管１２６を介して大気開放弁１２７が接続されている。受信テーブル１２４が気送管１０１の他端部に最も近接された実線で示す状態では、受信テーブル１２４が気送管１０１の他端部を閉塞し、さらに大気開放弁１２７を閉じた状態では、気送管１０１の他端部側における空気の出入りが制限される。以上のような構成を備えていることにより、気送管１０１の一端部、他端部を閉塞することが可能であり、気送管１０１の内部を全体にわたり気密状態とすることができる。また、気送管１０１の内径は、気送子１０の摺動体１２の外径寸法に対応して設定されるものであり、摺動体１２の外形寸法よりも僅かに大きい寸法で設定される。 The receiving station 120 has substantially the same configuration as the transmitting station 110, and the receiving table 124 is close to the other end of the pneumatic tube 101 (indicated by a solid line) and separated (indicated by a two-dot chain line). The lifting means 122 is driven so as to be driven. The elevating means 122 has the same configuration as the elevating means 112 described above, converts the rotational movement of the motor 121 into a linear movement via a ball screw (not shown) incorporated in the elevating means 122 and does not show the receiving table 124 It has a configuration for transmitting to the engaging portion, and has a function of advancing and retracting the reception table 124 with respect to the other end. A communication hole 125 is disposed on the reception table 124, and an air release valve 127 is connected via a pipe 126. In the state shown by the solid line where the reception table 124 is closest to the other end of the air pipe 101, the reception table 124 closes the other end of the air pipe 101, and in the state where the air release valve 127 is closed, Entry and exit of air at the other end side of the pneumatic tube 101 is restricted. By providing the above-described configuration, one end and the other end of the pneumatic tube 101 can be closed, and the inside of the pneumatic tube 101 can be entirely airtight. Further, the inner diameter of the pneumatic tube 101 is set corresponding to the outer diameter of the sliding body 12 of the pneumatic transducer 10, and is set to a size slightly larger than the outer size of the sliding body 12.
気送管装置１００によって気送子１０を移送する際は、まず、送信ステーション１１０において駆動手段１１２を作動し、送信テーブル１１４を１１４’で示す位置に移動させる。送信テーブル１１４を１１４’で示す位置に移動させたならば、気送子１０を送信テーブル１１４上にセットし、送信テーブル１１４を上昇させて、気送子１０を気送管１０１の一端部に挿入し、送信テーブル１１４で気送管１０１の一端部を閉塞する状態として大気開放弁１１７を閉じる。また、受信テーブル１２４も気送管１０１の他端部を閉塞する位置に位置付け、大気開放弁１２７を閉じて、気送管１０１の内部を気密状態とする。 In order to transport the pneumatic transducer 10 by the pneumatic tube device 100, first, the drive means 112 is operated at the transmitting station 110 to move the transmitting table 114 to the position indicated by 114 '. When the transmission table 114 is moved to the position indicated by 114 ′, the air mover 10 is set on the transmission table 114, and the transmission table 114 is raised to set the air mover 10 at one end of the air transfer tube 101. The air release valve 117 is closed in a state of inserting the air supply pipe 114 so as to close one end of the air supply pipe 101 with the transmission table 114. Further, the reception table 124 is also positioned at a position where the other end of the air pipe 101 is closed, and the air release valve 127 is closed to make the inside of the air pipe 101 airtight.
上記したように、気送子１０をセットしたならば、吸引源１３０のバルブ１３２を開放して吸引ポンプ１３１を作動し、気送管１０１の内部を減圧する。気送管１０１の内部が十分に減圧された状態になったならば、送信ステーション１１０の大気開放弁１１７を開放する。大気開放弁１１７が開放されると、気送子１０の気送管１０１側と、大気開放弁１１７側との間で気圧差が生じ、この気圧差があることにより、図中（ａ）で示す位置にある気送子１０が減圧された気送管１０１内の負圧によって吸引され、大気開放弁１１７から大気が導入されつつ、送信ステーション１１０から気送子１０が発進する。 As described above, when the pneumatic conveying member 10 is set, the valve 132 of the suction source 130 is opened, the suction pump 131 is operated, and the inside of the pneumatic tube 101 is depressurized. When the inside of the pneumatic tube 101 is fully depressurized, the air release valve 117 of the transmission station 110 is opened. When the air release valve 117 is opened, an air pressure difference occurs between the air tube 101 side of the air transmitter 10 and the air release valve 117 side, and this air pressure difference causes a difference in FIG. The air transmitter 10 at the position shown is sucked by the negative pressure in the air pipe 101 that has been depressurized, and while the air is introduced from the air release valve 117, the air transmitter 10 is started from the transmission station 110.
送信ステーション１１０から発進した気送子１０は、上記した気圧差によって気送管１０１を進み、その後、圧送手段１４０と気送管１０１との接続部を通過し、気送子１０が図中（ｂ）の位置に到達したことが図示しないセンサー等により確認されると、圧送手段１４０のバルブ１４２を開放すると共に圧送ポンプ１４１を作動し、吸引手段１３０のバルブ１３２を閉弁すると共に吸引ポンプ１３１を停止する。さらに、これと同時に、送信ステーション１１０の大気開放弁１１７を閉弁し、受信ステーション１２０の大気開放弁１２７を開放する。このようにすることで、気送子１０は、気送管１０１内において引き続き後方から圧送された空気により推進力を得て、さらに気送管１０１を進行することができる。 The air transmitter 10 which has been started from the transmission station 110 travels through the air pipe 101 by the above-mentioned air pressure difference, and then passes through the connection portion between the pumping means 140 and the air pipe 101, and the air transmitter 10 is shown in FIG. When it is confirmed by the sensor (not shown) that the position b) is reached, the valve 142 of the pumping means 140 is opened and the pumping pump 141 is operated to close the valve 132 of the suction means 130 and the suction pump 131. Stop. Furthermore, at the same time, the air release valve 117 of the transmission station 110 is closed, and the air release valve 127 of the reception station 120 is opened. By doing this, the pneumatic transducer 10 can continue to travel in the pneumatic tube 101 while obtaining propulsive force by the air that is continuously pumped from the rear in the pneumatic tube 101.
上記したように、圧送手段１４０が作動し、吸引手段１３０が停止されることにより気送子１０がさらに移送されて、受信ステーション１２０の受信テーブル１２４に到達する（図中（ｃ）で示す。）。なお、気送子１０が受信テーブル１２４に到達する前に、大気開放弁１２７を閉弁することで気送子１０と受信テーブル１２４との間にエアークッションを生成して、受信テーブル１２４に気送子１０が到達する際の衝撃を和らげるようにすることが好ましい。受信テーブル１２４に気送子１０が到達したならば、圧送手段１４０の作動を停止し、昇降手段１２２を作動して、受信テーブル１２４を１２４’で示す位置に下降させて気送子１０を取り出すことができる。 As described above, the pumping means 140 is activated and the suction means 130 is stopped to further transport the air carriage 10 to reach the reception table 124 of the receiving station 120 (indicated by (c) in the figure). ). Note that the air release valve 127 is closed before the air transfer element 10 reaches the reception table 124 to generate an air cushion between the air transfer element 10 and the reception table 124, and the air is transmitted to the reception table 124. It is preferable to reduce the impact when the feeding element 10 reaches. When the air transport member 10 reaches the reception table 124, the operation of the pumping means 140 is stopped and the lifting means 122 is operated to lower the reception table 124 to the position indicated by 124 'and take out the air transport member 10. be able to.
本実施形態における気送管１０１においては、各気送管構成部材１０２の第一の連結部１０４と第二の連結部１０５とが連結されると、テーパー部１０４ｂと逆テーパー部１０５ｂとが係合することによって、気送管１０１の連結部の内面側において段差が生じることがない。したがって、送信ステーション１１０から発進した気送子１０は気送管１０１内を詰まることなく受信ステーション１２０まで移動することができる。 In the pneumatic tube 101 of the present embodiment, when the first connecting portion 104 and the second connecting portion 105 of each pneumatic tube component 102 are connected, the tapered portion 104 b and the reverse tapered portion 105 b are engaged. As a result, the step does not occur on the inner surface side of the connecting portion of the pneumatic tube 101. Therefore, the air mover 10 started from the transmitting station 110 can move to the receiving station 120 without clogging the inside of the air tube 101.
