Description

本発明は、２００５年７月２８日に出願された米国出願第６０／７０３３０６号及び２００５年８月１日に出願された米国出願第６０／７０４２９０号の利益を主張する。   The present invention claims the benefit of US application 60/703306, filed July 28, 2005, and US application 60 / 704,290, filed August 1, 2005.

空気作動往復ピストンポンプは様々な分野のポンプにおいて周知である。一般にそのようなポンプは機械又は空気圧で稼動される空気バルブを有する事で、ピストンの両側への空気の流れを制御する。従来、そのようなポンプの制御はポンプ自体よりももたらされる流体の流れを監視及び制御する事によってなされてきた。グラコのEXTREME-MIX（商標）分配器のような従来の装置は制御のためにピストンの位置を監視する。
米国特許第５，１７４，７３１号公報 Air operated reciprocating piston pumps are well known in various fields of pumps. Generally, such pumps have air valves that are mechanically or pneumatically operated to control the flow of air to both sides of the piston. Traditionally, control of such pumps has been accomplished by monitoring and controlling fluid flow resulting from the pump itself. Conventional devices such as Graco's EXTREME-MIX ™ distributor monitor the position of the piston for control.
US Pat. No. 5,174,731

したがって、本発明の目的は、改良された監視と往復空気モータの制御とを可能にする事で、ピストンの位置と、回転及び流れの速さと、合計回転と、暴走の制御と、空気モータ及びポンプの下部部品の故障を診断する性能とをモニタすることを可能にする。   Accordingly, it is an object of the present invention to enable improved monitoring and control of the reciprocating air motor so that the piston position, rotation and flow speed, total rotation, runaway control, air motor and It is possible to monitor the performance of diagnosing faults in the lower parts of the pump.

制御には空気モータのバルブ（空気バルブ）に設置された磁石と、バルブカバーに設置された二つのリードセンサを用いる事で、バルブの速度及び位置を監視する。ソレノイドはバルブカバーに取付けられており、プランジャをバルブへと延ばすことで、バルブの動き、結果的に（一般に流体供給器が空になることによって生じる）ポンプの暴走を阻止するよう設定される。使用者のインターフェースは、ポンプを設定及び制御するためのＬＣＤ及びボタンを有する。ディスプレイは回転率、（様々な単位の）流速、合計回転、及び診断されたエラーを表示するためにトグルで留められている。設定パラメータは流体の単位（クォーツ、リッターなど）と暴走設定ポイントとを有する。 For control, the speed and position of the valve are monitored by using a magnet installed in the valve (pneumatic valve) of the air motor and two reed sensors installed in the valve cover. Solenoid is attached to the valve cover, by extending the plunger into the valves are set so as to prevent movement of the valve, as a result, the (typically caused by the fluid supply is empty) runaway of the pump . The user interface has an LCD and buttons for setting and controlling the pump. The display is toggled to show rotation rate, flow rate (in various units), total rotation, and diagnosed errors. The set parameters include fluid units (quartz, liter, etc.) and runaway set points.

リードスイッチ及び磁石は、いつ空気バルブがそれぞれのストロークの限界点、移行点又はその両方に存在するかを検出するために設置されている。コントローラは、空気バルブの位置を変化させる事によって稼動されるリードスイッチの開閉を数える事で、モータが動く速度を算出する。そして、コントローラはその速度を事前にプログラムされた値と比較する事で、空気モータが暴走状態にあるかどうかを決定する。その状態にあるときには、コントローラは切り替えを阻止するソレノイドを稼動させ、それによってモータを停止させる。   Reed switches and magnets are installed to detect when an air valve is present at each stroke limit, transition point, or both. The controller calculates the speed at which the motor moves by counting the opening and closing of the reed switch that is activated by changing the position of the air valve. The controller then determines whether the air motor is in a runaway state by comparing its speed with a preprogrammed value. When in that state, the controller activates a solenoid that prevents switching, thereby stopping the motor.

磁気抵抗センサがピストンの位置を正確に監視するために空気モータの中心に配置される。このセンサからのデータは空気バルブセンサからのデータと共に正確な制御及びポンプの診断に必要な入力を提供し、測定及び複数の部品装置にそれを適合させる。   A magnetoresistive sensor is placed in the center of the air motor to accurately monitor the position of the piston. The data from this sensor along with the data from the air valve sensor provide the necessary inputs for accurate control and pump diagnostics and adapt it to the measurement and multi-part device.

これら及び他の目的と発明の利点とは添付図面と共になされる以下の説明によってより十分に明らかになるであろう。添付図面において、類似の参照番号はいくつかの図面を通して同一又は類似の部品を示す。   These and other objects and advantages of the invention will become more fully apparent from the following description taken in conjunction with the accompanying drawings. In the accompanying drawings, like reference numerals designate identical or similar parts throughout the several views.

空気作動往復ビストンポンプ１０において、コントローラ１２は空気モータ１８のバルブ（空気バルブ）１６に取付けられた磁石１４と、バルブカバー２２に取付けられた二つのリードセンサ２０とを用いて、バルブ１６の速度と位置とをモニタする。ソレノイド２４はバルブカバー２２に取付けられており、バルブ１６にプランジャ２６を突き出す事でバルブの動き、結果的に（一般に流体供給器が空になる、又は別の供給管のホースが漏れ／破損を有する事によって起こる）ポンプ１０の暴走を止めるよう設定されている。使用者のインターフェース２８は、ポンプ１０を設定及び制御するためのＬＣＤディスプレイ３０とボタン３２とを有する。ディスプレイ３０は回転率、（様々な単位の）流速、合計回転及び診断したエラーを表示するためにトグルで留められている。設定パラメータは流体の単位（クォーツ、リッターなど）及び暴走設定点を含むことができる。

In the air-operated reciprocating biston pump 10, the controller 12 uses the magnet 14 attached to the valve (air valve) 16 of the air motor 18 and the two reed sensors 20 attached to the valve cover 22 to speed the valve 16. And monitor position. Solenoid 24 is attached to the valve cover 22, valves 1 6 of the valve by projecting the plunger 26 moves, resulting in (generally fluid supply is emptied, or another hose of the supply pipe leakage / It is set to stop the runaway of the pump 10 (caused by having a break). The user interface 28 has an LCD display 30 and buttons 32 for setting and controlling the pump 10. The display 30 is toggled to display rotation rate, flow rate (in various units), total rotation and diagnosed errors. Setting parameters can include fluid units (quartz, liter, etc.) and runaway set points.

リードスイッチ２０及び磁石１４は、いつ空気バルブ１６がそれぞれのストロークの限界位置、移行位置又はその両方にあるかを検出するために配置されている。コントローラ１２は、空気バルブ１６の位置を変更する事によって稼動されるリードスイッチ２０の開閉を数える事によって、モータ１８が動いている速度を算出する。そして、コントローラ１２はその値を予め記録された値と比較することによって、空気モータ１８が暴走状態にあるかどうかを決定する。その状態にある場合、コントローラ１２は、切り替えを阻止するソレノイド２４を稼動させる事で、モータ１８を停止させる。これは流体の流出及び／又はポンプの損傷を阻止するために行われる。   Reed switch 20 and magnet 14 are arranged to detect when air valve 16 is at the limit position, transition position, or both of each stroke. The controller 12 calculates the speed at which the motor 18 is moving by counting the opening and closing of the reed switch 20 that is operated by changing the position of the air valve 16. The controller 12 then compares the value with a pre-recorded value to determine whether the air motor 18 is in a runaway state. In this state, the controller 12 stops the motor 18 by operating the solenoid 24 that prevents switching. This is done to prevent fluid spillage and / or pump damage.

磁気抵抗センサ３４は空気モータ１８の中心に配置される事によって、ピストン３６の位置を正確にモニタする。このセンサ３４からのデータは空気バルブセンサ２０からのデータと共にポンプ１０の正確な制御及び診断に必要な入力を提供し、それを測定及び複数の部品適用に適合させる。   The magnetoresistive sensor 34 is disposed at the center of the air motor 18 so that the position of the piston 36 is accurately monitored. The data from this sensor 34 along with the data from the air valve sensor 20 provide the necessary input for accurate control and diagnosis of the pump 10 to adapt it for measurement and multi-part applications.

様々な変更及び改良が以下の請求項によって規定される発明の精神及び範囲から逸脱することなくポンプの制御にもたらされることが想定される。   It is envisioned that various changes and modifications may be made to the control of the pump without departing from the spirit and scope of the invention as defined by the following claims.
