【発明の属する技術分野】
本発明は、空気流を利用して物を送る気送設備において、その物の受信位置においてその物に衝撃を与えることなく受け止める方法及び装置に関する。
【0002】
【従来の技術】
物を移送する設備として、物を送る位置(送信位置)と物を受ける位置(受信位置)との間に配管を設け、送信位置より配管内に投入された気送対象物を、排風機によりこの配管内に生じさせた空気流の力により受信位置まで移送する気送設備(空気搬送設備)が知られている。このような設備は、試料の採取建屋とその分析建屋との間のように施設の建屋間などで物を搬送するのに用いられることがある。
【0003】
【発明が解決しようとする課題】
ところで、上記のような建屋間で物を搬送する場合、汚染物のように、搬送する物によっては建屋間の移動時間をできるだけ短くした方がよい場合がある。従って、移送対象物によっては、移送速度を更に高速にすることが求められる。例えば、数100mの距離を10〜20m/sの速度で移送することが求められる。しかも、移送の制御を容易にするためには速度にムラがないことも要求される。
【0004】
しかし、移送対象物を高速度で移送するようにすると、その受信位置ではかなりの衝撃を受けることになり、移送対象物によっては破損のおそれが生じる。
【0005】
本願に係る発明は、上記のような状況に鑑み、気送設備において高速で移送される気送対象物が受信位置において衝撃を緩和されて受信されるようにすることを目的とする。
【0012】
【課題を解決するための手段】
上記課題を解決する本願の第1の発明は、送信位置から受信位置にかけて配管を設けると共に、当該配管に排風機を接続し、前記送信位置から前記配管内に入れられる移送対象物を、前記排風機により前記配管内に発生される空気流の力により前記受信位置に移送する気送設備において、前記受信位置は前記配管の鉛直下降部に設けられ、前記移送対象物が前記受信位置に到達する前に前記排風機を停止するに際し、空気流量が31m 3 /hの場合には、前記排風機を停止する前記気送対象物の位置Xsと前記受信位置における前記気送対象物の速度Vfとの関係式Vf=−Xs+15に基づき、前記気送対象物が前記受信位置において所望の速度となるように前記排風機の停止を制御することを特徴とする気送設備における受信方法である。
【0013】
この第1の発明に係る受信方法によれば、排風機を停止する前記気送対象物の位置と前記受信位置における前記気送対象物との速度の関係を求めておき、この関係に基づいて排風機の停止を制御するようにしたので、気送対象物を所望とする速度に減じさせて受信位置に至らせることができる。
【0014】
上記課題を解決する本願の第2の発明は、第1の発明に係る気送設備における受信方法において、前記受信位置においては前記移送対象物が前記受信位置における空気を圧縮するようにしたことを特徴とする気送設備における受信方法である。
【0015】
この第2の発明に係る受信方法によれば、受信位置においては気送対象物が空気を圧縮しながら受信位置に到達するので、気送対象物は速度を減じられて受信位置に軟着陸することになる。
【0016】
上記課題を解決する本願の第3の発明は、第1の発明に係る気送設備における受信方法において、前記受信位置を機密構造とし、前記移送対象物が受信位置において空気を圧縮するようにしたことを特徴とする気送設備における受信方法である。
【0017】
この第3の発明に係る受信装置によれば、受信位置を機密構造してあるので、気送対象物が機密構造部分において空気を圧縮することにより、気送対象物自体が減速されて受信位置に至ることになる。
【0018】
【発明の実施の形態】
次に、本願に係る発明の実施の形態につき、図面に基づき説明する。
図1は、本発明の実施の一形態に係る受信装置を含む気送設備全体の概略図である。
【0019】
図1において、1は送信位置と受信位置との間に配管された気送管であり、その送信位置には気送対象物である気送子2を気送管1内に装入するための送信装置3が設けられており、受信位置には気送子2を受け、更に取り出すための受信装置4が設けられている。送信位置において気送管1には、大気中に開放する給気管5が接続されており、この給気管5には、フィルタ6、給気弁7が設けられている。尚、気送管1は、送信位置から受信位置にかけて、つまり全長にわたり密封構造に構成される。また、図では表してはいないが、気送管1は、その曲がり部等では適宜曲率が付けられている。気送管1の途中には、移送先を切り換えるための管路切り換え器(ダイバータ)15が設けられることもある。
【0020】
気送管1における受信位置寄りの位置には、フィルタ8、排気弁9を備えた給気管10を介して排風機11が接続されている。この排風機11の駆動することにより、給気管5から空気が吸引され、気送管1内に空気流12が生ぜられる。空気流12の速度は、排風機11の容量によるが、給気弁7、排気弁9の開閉量を変えることによっても制御することができる。この空気流12により、気送子2を所望の速度で送れる状態になると送信装置3により気送管1内に気送子2が投入される。気送子2としては、例えばジャグと呼ばれる容器が使われ、その中に採取された試料等が収容される。気送子2の外形は、気送管1の内径に応じた寸法とされる。
【0021】
排風機11を接続するための給気管10より更に上流側(送信位置側)の所定の位置に気送子2の通過を検知する通過検知装置13が設置され、この通過検知装置13の検知信号は制御装置14に入力される。通過検知装置13としては、電気的、光学的、磁気的なもの及びその他種々のものが採用可能である。制御装置14は、通過検知装置13による気送子2通過の検出信号を受けて排風機11にその駆動を停止する指令を出すものである。
【0022】
上記気送設備において、気送子2の移送及び受信は次のようにしてなされる。まず、排風機11を駆動し、送信位置側の給気管5から排風機11外へ至る空気流12を気送管1内に生じさせる。この空気流12の流量が所定の値になると、送信装置3より気送管1内に気送子2が投入される。気送管1内に投入された気送子2は空気流12により初期の速度(例えば、10〜20m/s)で移送される。気送子2が通過検知装置13を通過すると、それが通過検出装置13により検出され、検出結果が制御装置14に入力され、それに基づき排風機11の停止が制御される。
【0023】
排風機11が停止されることにより、気送管1内の空気流速が減速される。このとき、気送子2は、空気流速に対しある程度遅れて移送されるが、空気流速の減速によりこの気送速度も減速される。従って、受信装置4における気送子2の受信時の速度も減速され、気送子2の受信時の衝撃は緩和される。
【0024】
図2には、衝撃力が緩和された様子を示す。図中、白丸が従来の受信速度及び衝撃力を示し、黒丸が本実施形態による受信速度及び衝撃力を示す。図中、J1 、J2 は気送子2の質量の違うものを示す。
【0025】
上述のように、通過検知装置13が気送子2を検出したことに応じて、排風機11の停止を制御するに際し、気送子2がどの位置にあるときに排風機11を停止するかをより正確に行うことにより、気送子2の到着に支障を来すことなく、気送子2の受信衝撃を効率的に緩和することができる。
【0026】
そのため、予め排風機11の停止時の気送子2の位置(受信位置からの距離:xs )と受信位置での気送子2の受信時の速度との関係を試験等により求めておく。図3には、その結果を示し、このグラフより式(1)のモデル式が求められる。
【0027】
【数1】
vf =−xs +15 ・・・ (1)
【0028】
図3及びモデル式にからわかるように、排風機11の停止したときの気送子2の位置による受信速度の変化はほぼ線形となっており、受信速度は排風機11を停止したときの気送子2の位置の一次式で近似できる。図3には、異なる空気流量における受信速度のグラフが示してあり、流量の変化によりモデル式も変わることがわかる。Aが空気流量31m3 /hの場合であり、Bが空気流量26m3 /hのものである。尚、図3において、各グラフの右側の縦線は軟着陸限界を示す。つまり、この線を超える距離では気送子2は受信位置に到達できなくなる。
【0029】
このように、モデル式を求めおき制御装置14に記憶させておく。所定の空気流量の空気流により移送されている移送子2が通過検知装置13により検出されると、モデル式より移送子2がどの位置に来たときに排風機11を停止すればよいかが求められ、それに基づき排風機11が停止される。気送子2が所定の位置に来たことの判定手段としては種々のものが考えられるが、例えば、通過検知装置13が気送子2を検出してからの時間をタイマによりカウントして停止指令を排風機11に指令するようにすればよい。また、モデル式より、どの位置に気送子2が来たときに排風機11を停止すればよいのかがわかるので、その位置に通過検知装置13をセットすればよい。
【0030】
上記実施の形態は、受信位置が鉛直下降部にある場合であるが、図4に示すように、受信位置が水平部に存在する場合でも同様に適用することができる。
【0031】
図5には本発明の受信装置の他の実施の形態を示す。これは、気送管1の排風機11から受信装置4に至る気送管部(気密構造部分)1aを、気送子2の外形との間に適当な隙間を設けた気密構造としたものである。図5に機密構造部1aの効果を確かめるために実験的に使用した空気管21及び弁22も併せて示してある。図中、Lは受信位置から弁22までの距離である。
【0032】
この受信装置によれば、排風機11がつながる排気管10の接続位置を通過した気送子2は気密構造部分1aに入り、気密構造部分1a内の空気を圧縮しながら下降する。つまり、受信箇所に進む気送子2は、気密構造部分1a内の空気(以下、受信側空気)に対し、これを圧縮する力として作用する。気送子2と気送管1との隙間から空気は進行方向と反対側に流れるが、受信箇所が機密構造であれば、隙間の流れを考慮しても受信側空気は圧縮される。このとき、圧縮された受信側空気は、気送子2に対し、進行方向と反対の方向の押す力として作用する。この力により、気送子2の速度(気送速度)は減速され、受信時の速度は小さくなる。よって、気送子2は受信位置に軟着陸し、衝撃は緩和される。
【0033】
図6、図7には、受信側空気量と受信時の衝撃力、受信速度との関係をグラフでそれぞれ示してある。尚、受信側の空気量は、受信位置から弁22までの距離に比例し、これを変化させた場合の受信速度の変化を示す。受信時の衝撃力、受信速度は気送子2の速度によって当然変り、図6、図7において、aは気送子2が30gのものの場合、bは気送子2が20gのものの場合である。
【0034】
図6、図7より、受信側空気の量が少ないほど受信速度は小さくなることがわかる。つまり、図6、図7は受信側空気の量がある程度以上大きくなると受信速度はほぼ一定となるが、これは受信側空気が大きいと空気の圧縮による減速効果がほとんどなくなることを示しているのである。従来の方法による受信速度は、この効果がほとんどなくなるときの速度またはそれ以上となり、本発明によると従来に対し最大約50%の減速、また襲撃力は1/3までの減少効果が得られている。よって、本発明の適用にあたっては、受信箇所を機密構造とし、かつ受信箇所の空気容量を少なくすることに可能であり、特別に装置を設置する必要がない。
【0035】
この受信装置は、前述の排風機11を早期に停止させる構造と組み合わせることも可能である。その場合には、排風機11の停止のタイミングと受信側の空気量を調整することにより効果的な軟着陸を達成することができる。
【0036】
本発明に係る気送設備の受信装置は、すべての分野の気送設備に利用できるが、特に気送対象物を高速で搬送する設備においては極めて有効である。また、その構造は、上述のものに限らず、種々の態様で実施可能である。
【0040】
【発明の効果】
本願の第1の発明に係る気送設備における受信方法によれば、送信位置から受信位置にかけて配管を設けると共に、当該配管に排風機を接続し、前記送信位置から前記配管内に入れられる移送対象物を、前記排風機により前記配管内に発生される空気流の力により前記受信位置に移送する気送設備において、前記受信位置は前記配管の鉛直下降部に設けられ、前記移送対象物が前記受信位置に到達する前に前記排風機を停止するに際し、空気流量が31m 3 /hの場合には、前記排風機を停止する前記気送対象物の位置Xsと前記受信位置における前記気送対象物の速度Vfとの関係式Vf=−Xs+15に基づき、前記気送対象物が前記受信位置において所望の速度となるように前記排風機の停止を制御するようにしたので、気送対象物を所望とする速度に減じさせて受信位置に至らせることができる。
【0041】
本願の第2の発明に係る気送設備における受信方法によれば、第1の発明に係る気送設備における受信方法において、前記受信位置においては前記移送対象物が前記受信位置における空気を圧縮することにより受信されるようにしたので、気送対象物は速度を減じられて受信位置に軟着陸することになり、受信時の衝撃力を少なくすることができる。よって、破損の恐れのあるものや慎重に取り扱う必要のあるものを気送する場合、また質量の大きいものを気送する場合、長距離の移送や減速が期待できない受信装置を用いる等、受信速度が高速度になる場合に特に有効である。
【0042】
本願の第3の発明に係る気送設備における受信方法によれば、第1の発明に係る気送設備における受信方法において、前記受信位置を機密構造とし、前記移送対象物が受信位置において空気を圧縮することにより受信されるようにしたので、気送対象物自体が減速されて受信位置に至ることになり、受信時の衝撃力を少なくすることができる。
【0043】
この第3の発明の実施にあたっては、受信箇所を機密構造かつ受信箇所の空気容積を少なくすることにより可能であり、特別に装置を設置する必要がなく、コストの面でも有利である。また、受信箇所に給気管等気送管以外の配管が接続されていない場合は、受信箇所を機密構造とすることだけで十分な減速、衝撃力減少の効果が得られる。更に、気送設備だけでなく、固体物を受信する場合に、その固体物の大きさに合わせた管を受信ルートに設置することにより、本発明を適用し、受信時の衝撃を緩和することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a method and an apparatus for receiving an object at a receiving position of the object in an air-feeding facility that sends the object using an air flow without impacting the object.
[0002]
[Prior art]
As equipment for transporting objects, a pipe is provided between the position where the object is sent (transmission position) and the position where the object is received (reception position). There is known an air-feeding facility (air-transporting facility) that moves to a receiving position by the force of an air flow generated in the pipe. Such equipment may be used to transport objects between facility buildings, such as between a sample collection building and its analysis building.
[0003]
[Problems to be solved by the invention]
By the way, when an object is transported between buildings as described above, depending on the object to be transported, such as a contaminated material, it may be desirable to shorten the movement time between buildings as much as possible. Therefore, depending on the transfer object, it is required to further increase the transfer speed. For example, it is required to transport a distance of several hundred meters at a speed of 10 to 20 m / s. In addition, the speed is required to be uniform in order to facilitate the transfer control.
[0004]
However, if the object to be transferred is transferred at a high speed, the receiving position receives a considerable impact, and there is a risk of damage depending on the object to be transferred.
[0005]
In view of the above situation, an object of the present invention is to allow a pneumatic object to be transported at high speed in a pneumatic facility to be received with a shock reduced at a reception position.
[0012]
[Means for Solving the Problems]
The first invention of the present application that solves the above-mentioned problems is to provide a pipe from the transmission position to the reception position, connect an exhaust fan to the pipe, and transfer the object to be transferred that is put into the pipe from the transmission position. In the air-feeding facility for transferring to the receiving position by the force of the air flow generated in the pipe by the air blower, the receiving position is provided in a vertically descending portion of the pipe, and the transfer object reaches the receiving position. When stopping the exhaust fan before, if the air flow rate is 31 m 3 / h, the position Xs of the air supply object that stops the air exhaust and the speed Vf of the air supply object at the reception position based on the relationship Vf = -Xs + 15, is a reception method in mind transmission equipment, characterized in that the gas-feeding the object to control the stopping of the air blower so that the desired speed at the receiving position
[0013]
According to the receiving method according to the first aspect of the present invention, the relationship between the position of the air sending object that stops the exhaust fan and the speed of the air sending object at the receiving position is obtained, and based on this relationship. Since the stop of the exhaust fan is controlled, the object to be aired can be reduced to a desired speed to reach the reception position.
[0014]
According to a second aspect of the present invention for solving the above-mentioned problem, in the receiving method in the pneumatic equipment according to the first aspect , the transfer object compresses the air at the receiving position at the receiving position. It is the receiving method in the characteristic pneumatic equipment.
[0015]
According to the receiving method of the second aspect of the invention, since the air transportation object reaches the reception position while compressing the air at the reception position, the air transportation object is softly landed at the reception position at a reduced speed. become.
[0016]
According to a third invention of the present application for solving the above-mentioned problems, in the receiving method in the pneumatic equipment according to the first invention, the receiving position is a confidential structure, and the transfer object compresses air at the receiving position. This is a receiving method in the pneumatic equipment.
[0017]
According to the third aspect of the invention, since the receiving position has a confidential structure, the pneumatic object is compressed in the confidential structure portion, whereby the pneumatic object itself is decelerated and the receiving position is compressed. It will lead to.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the invention according to the present application will be described with reference to the drawings.
FIG. 1 is a schematic diagram of an entire pneumatic facility including a receiving device according to an embodiment of the present invention.
[0019]
In FIG. 1, reference numeral 1 denotes an air feeding pipe that is piped between a transmission position and a reception position, and an air feeding element 2 that is an air feeding object is inserted into the air feeding pipe 1 at the transmission position. The receiving device 4 is provided at the receiving position for receiving and further taking out the air carrier 2. At the transmission position, an air supply pipe 5 that is open to the atmosphere is connected to the air supply pipe 1, and a filter 6 and an air supply valve 7 are provided in the air supply pipe 5. The pneumatic tube 1 is configured in a sealed structure from the transmission position to the reception position, that is, over the entire length. Further, although not shown in the figure, the air pipe 1 is appropriately curved at the bent portion or the like. A pipe switching device (diverter) 15 for switching the transfer destination may be provided in the middle of the air feeding tube 1.
[0020]
An exhaust fan 11 is connected to a position near the reception position in the air pipe 1 through an air supply pipe 10 provided with a filter 8 and an exhaust valve 9. By driving the exhaust fan 11, air is sucked from the air supply pipe 5, and an air flow 12 is generated in the air supply pipe 1. The speed of the air flow 12 depends on the capacity of the exhaust fan 11, but can also be controlled by changing the opening / closing amounts of the air supply valve 7 and the exhaust valve 9. When the air flow 12 is in a state where the air feed 2 can be sent at a desired speed, the air feed 2 is introduced into the air feed tube 1 by the transmission device 3. As the air carrier 2, for example, a container called a jug is used, and a sample collected therein is accommodated. The outer shape of the air carrier 2 is a dimension corresponding to the inner diameter of the air tube 1.
[0021]
A passage detection device 13 for detecting the passage of the air carrier 2 is installed at a predetermined position further upstream (transmission position side) than the air supply pipe 10 for connecting the exhaust fan 11, and a detection signal of the passage detection device 13 Is input to the control device 14. As the passage detection device 13, an electrical, optical, magnetic, and other various devices can be adopted. The control device 14 receives the detection signal of the air feed 2 passing by the passage detection device 13 and issues a command to stop the drive to the exhaust fan 11.
[0022]
In the above-mentioned pneumatic transportation equipment, the pneumatic carrier 2 is transferred and received as follows. First, the exhaust fan 11 is driven, and an air flow 12 from the air supply pipe 5 on the transmission position side to the outside of the exhaust fan 11 is generated in the air supply pipe 1. When the flow rate of the air flow 12 reaches a predetermined value, the air feeding element 2 is introduced into the air feeding pipe 1 from the transmission device 3. The pneumatic carrier 2 introduced into the pneumatic pipe 1 is transferred at an initial speed (for example, 10 to 20 m / s) by the air flow 12. When the air carrier 2 passes through the passage detection device 13, it is detected by the passage detection device 13, and the detection result is input to the control device 14, and the stop of the exhaust fan 11 is controlled based on the detection result.
[0023]
By stopping the exhaust fan 11, the air flow velocity in the air pipe 1 is decelerated. At this time, the air carrier 2 is transferred with a certain delay from the air flow velocity, but the air conveyance speed is also reduced by the reduction of the air flow velocity. Therefore, the speed at the time of reception of the air carrier 2 in the receiving device 4 is also reduced, and the impact at the time of reception of the air carrier 2 is mitigated.
[0024]
FIG. 2 shows how the impact force is relaxed. In the figure, white circles indicate conventional reception speed and impact force, and black circles indicate reception speed and impact force according to the present embodiment. In the figure, J 1 and J 2 indicate different masses of the air carrier 2.
[0025]
As described above, when controlling the stop of the exhaust fan 11 in response to the passage detecting device 13 detecting the air exhaust 2, the exhaust fan 11 is stopped at which position. By performing more accurately, the reception shock of the air carrier 2 can be effectively reduced without hindering the arrival of the air carrier 2.
[0026]
Therefore, the relationship between the position of the pneumatic feeder 2 (distance from the reception position: x s ) when the exhaust fan 11 is stopped and the speed at the time of reception of the pneumatic feeder 2 at the reception position is obtained in advance by a test or the like. . FIG. 3 shows the result. From this graph, the model equation (1) is obtained.
[0027]
[Expression 1]
v f = −x s +15 (1)
[0028]
As can be seen from FIG. 3 and the model formula, the change in the reception speed due to the position of the air feed 2 when the exhaust fan 11 is stopped is almost linear, and the reception speed is the same as when the exhaust fan 11 is stopped. It can be approximated by a linear expression of the position of the feed 2. FIG. 3 shows a graph of the reception speed at different air flow rates, and it can be seen that the model formula also changes with changes in the flow rate. A is the case of the air flow rate 31m 3 / h, B is of the air flow rate 26m 3 / h. In FIG. 3, the vertical line on the right side of each graph indicates the soft landing limit. That is, the air carrier 2 cannot reach the reception position at a distance exceeding this line.
[0029]
In this way, the model formula is obtained and stored in the control device 14. When the transfer element 2 being transferred by the air flow having a predetermined air flow rate is detected by the passage detection device 13, it is determined from the model formula which position the transfer element 2 should come to be stopped when the transfer element 2 comes to. The exhaust fan 11 is stopped based on this. Various means may be considered as means for determining that the air carrier 2 has reached a predetermined position. For example, the time after the passage detector 13 detects the air carrier 2 is counted by a timer and stopped. A command may be issued to the exhaust fan 11. Moreover, since it can be understood from the model formula at which position the air exhaust element 2 should be stopped when the air carrier 2 comes, the passage detection device 13 may be set at that position.
[0030]
Although the above embodiment is a case where the reception position is in the vertical descending portion, as shown in FIG. 4, it can be similarly applied even when the reception position is in the horizontal portion.
[0031]
FIG. 5 shows another embodiment of the receiving apparatus of the present invention. This is an airtight tube structure (airtight structure portion) 1a extending from the exhauster 11 to the receiver 4 of the airline tube 1 with an appropriate gap between the outer shape of the airliner 2. It is. FIG. 5 also shows the
[0032]
According to this receiving apparatus, the air feed element 2 that has passed through the connection position of the exhaust pipe 10 to which the exhaust fan 11 is connected enters the airtight structure portion 1a and descends while compressing the air in the airtight structure portion 1a. That is, the air carrier 2 that travels to the reception location acts on the air in the airtight structure portion 1a (hereinafter referred to as reception-side air) as a force for compressing it. Air flows from the gap between the air carrier 2 and the air pipe 1 to the opposite side of the traveling direction. However, if the reception location is a confidential structure, the reception side air is compressed even if the flow of the gap is taken into consideration. At this time, the compressed reception side air acts on the air carrier 2 as a pushing force in the direction opposite to the traveling direction. By this force, the speed of the pneumatic feeder 2 (pneumatic speed) is reduced, and the speed at the time of reception becomes small. Therefore, the air carrier 2 is softly landed at the receiving position, and the impact is alleviated.
[0033]
FIGS. 6 and 7 are graphs showing the relationship between the reception-side air amount, the impact force during reception, and the reception speed, respectively. The air amount on the reception side is proportional to the distance from the reception position to the
[0034]
6 and 7 that the reception speed decreases as the amount of air on the reception side decreases. That is, FIGS. 6 and 7 show that the receiving speed becomes almost constant when the amount of air on the receiving side becomes larger than a certain level, but this shows that the deceleration effect due to air compression is almost lost when the air on the receiving side is large. is there. The reception speed according to the conventional method is a speed at which this effect is almost lost or higher, and according to the present invention, the maximum speed is reduced by about 50%, and the attack power is reduced to 1/3. Yes. Therefore, in applying the present invention, it is possible to make the reception location a confidential structure and reduce the air capacity of the reception location, and it is not necessary to install a special device.
[0035]
This receiving device can also be combined with a structure for stopping the above-described exhaust fan 11 at an early stage. In that case, effective soft landing can be achieved by adjusting the timing of stopping the exhaust fan 11 and the amount of air on the receiving side.
[0036]
The receiving device for an air transportation facility according to the present invention can be used for an air transportation facility in all fields, but is particularly effective in an equipment for transporting an air transportation object at a high speed. Further, the structure is not limited to the above-described structure, and can be implemented in various modes.
[0040]
【The invention's effect】
According to the receiving method in the air transportation facility according to the first invention of the present application, a pipe is provided from the transmission position to the reception position, and a blower is connected to the pipe, and the transfer target is placed in the pipe from the transmission position. In the pneumatic equipment for transferring the object to the reception position by the force of the air flow generated in the pipe by the exhaust fan, the reception position is provided in a vertically descending portion of the pipe, and the transfer object is the When stopping the exhaust fan before reaching the reception position, when the air flow rate is 31 m 3 / h, the position Xs of the air supply object at which the exhaust fan is stopped and the air supply object at the reception position based on the relationship Vf = -Xs + 15 of the speed Vf of the object, since the gas feed object was to control the stopping of the air blower so that the desired speed at the receiving position, the air feed object Can be brought to the receiving position let subtracting the rate of the Nozomu.
[0041]
According to the receiving method in the pneumatic equipment according to the second invention of the present application, in the receiving method in the pneumatic equipment according to the first invention, in the receiving position, the transfer object compresses the air in the receiving position. Therefore, the object to be aired is reduced in speed and softly landed at the receiving position, and the impact force at the time of reception can be reduced. Therefore, if you are transporting something that may be damaged or need to be handled carefully, or if you are transporting something with a large mass, use a receiver that cannot expect long-distance transport or deceleration, etc. This is particularly effective when the speed is high.
[0042]
According to a third mind sending and receiving method in a facility according to the invention of the present application, the receiving method in mind feeding equipment according to the first aspect of the invention, the received positions and sensitive structure, the transfer object air in the receiving position Since it is made to receive by compressing, the pneumatic object itself is decelerated and reaches the reception position, and the impact force at the time of reception can be reduced.
[0043]
In implementing the third aspect of the invention, it is possible to secure the receiving location by reducing the air volume of the receiving location and reducing the air volume of the receiving location, and it is not necessary to install a special device, which is advantageous in terms of cost. In addition, when a pipe other than an air feed pipe such as an air supply pipe is not connected to the reception location, a sufficient deceleration and impact force reduction effect can be obtained only by making the reception location a confidential structure. Furthermore, when receiving not only pneumatic equipment but also solid objects, the present invention can be applied to reduce the impact during reception by installing a pipe that matches the size of the solid object in the reception route. Can do.
