Description

この発明は、容器(例えばドラム缶)に収容されている接着剤などの粘性流体を使用場所(例えば自動ガン、手動ガン又は定量吐出装置)に移送し、前記容器内が空になり、他の容器に移す際に、空になった容器の残留接着剤などを可及的に少なくすることを目的とした粘性流体の移送における残量低減方法及びシステムに関する。   In the present invention, a viscous fluid such as an adhesive contained in a container (for example, a drum can) is transferred to a place of use (for example, an automatic gun, a manual gun, or a metering discharge device), the inside of the container becomes empty, and another container The present invention relates to a method and a system for reducing the remaining amount in the transfer of viscous fluid for the purpose of reducing residual adhesive and the like in an empty container as much as possible.

従来前使用のドラム缶の粘性流体がなくなってから、後使用のドラム缶の中身を使用するが、前使用のドラム缶内残留接着剤は可及的に少ない方が良いけれども、残留量を正確に認知することは至難とされていた。そこで安全の為に残留粘性流体が多少多目に残っている間に、前使用のドラム缶からの取り出しを終了させて、後使用のドラム缶に取り換えていたので、残留接着剤が15kg以上になることは珍しくなかった。
特開2001−263222 特開平9−67547
Conventionally, the contents of the drum can be used after the viscous fluid of the drum can be used after the previous use, but the residual adhesive in the drum can should be as little as possible, but the residual amount can be accurately recognized. It was considered difficult. Therefore, for the sake of safety, while the residual viscous fluid remains somewhat large, the removal from the drum cans of the previous use was terminated and replaced with drums for the later use, so the residual adhesive would be 15 kg or more. Was not uncommon.
JP 2001-263222 A JP-A-9-67547

前記従来の装置によれば、ドラム缶内の接着剤の残留量は、使用者の勘に頼っていたので、一定の残留量とすることは至難であった。即ち、残留粘性流体が過少に過ぎると、吸込みに際し、空気を吸入する為に、前記粘性流体中に気泡を含むことになり、接着不良その他の問題点を生じるおそれがあった。   According to the conventional apparatus, since the residual amount of the adhesive in the drum can depends on the user's intuition, it is difficult to make the residual amount constant. That is, if the residual viscous fluid is too small, air is sucked in at the time of suction, and bubbles are included in the viscous fluid, which may cause poor adhesion and other problems.

前記問題点を解決する為に、残留流体が多少多目の間に容器を取り換えることにすれば、気泡が混入するおそれは少ないが、結果的に不使用の粘性流体(残留粘性流体)が多量となり、実質不経済となる問題点があった。即ち、残留粘性流体を定量的に明らかにするのは至難であった。   In order to solve the above problem, if the container is replaced while the residual fluid is somewhat large, there is little risk of bubbles being introduced, but as a result, a large amount of unused viscous fluid (residual viscous fluid) is present. As a result, there was a problem that was actually uneconomical. That is, it is difficult to quantitatively clarify the residual viscous fluid.

然るにこの発明は、容器内の粘性流体量が少なくなると、その移送中に、ポンプシャフトの上昇下降スピードに変化を生じること、ポンプ出口以降の圧力に変動を来すこと及びエレベーターポンプの下降量に変化を生じるなどの知見を得たので、前記3点中少なくとも1点を検知(測定)することにより、前記従来の問題点を解決したのである。   However, according to the present invention, when the amount of viscous fluid in the container decreases, the pump shaft rises and falls during the transfer, the pressure after the pump outlet fluctuates, and the elevator pump descends. Since knowledge such as a change was obtained, at least one of the three points was detected (measured), thereby solving the conventional problem.

即ち方法の発明は、粘性流体を供給する方法において、ポンプシャフトの上昇、下降スピード変化の検出、ポンプ出口以降の圧力変化の検出、又はエレベーターポンプの下降量の変化の検出の中の少なくとも1つを具備させることにより粘性流体の残量を検出し、該検出の出力により切り替えを指示することを特徴とした粘性流体の移送における残量低減方法であり、ポンプシャフトの上昇、下降スピード変化の検出、ポンプ出口以降の圧力変化の検出及びエレベーターポンプの下降量の変化の検出を行うものである。   That is, the method invention is a method for supplying viscous fluid, wherein at least one of pump shaft ascending, descending speed change detection, pressure change after pump outlet detection, or elevator pump descending change detection is detected. The remaining amount of the viscous fluid is detected and the switching is instructed by the output of the detection, and the remaining amount is reduced in the transfer of the viscous fluid. The pressure change after the pump outlet is detected and the change in the descending amount of the elevator pump is detected.

またシステムの発明は、粘性流体を供給するシステムにおいて、ポンプシャフトの上昇、下降スピード変化の検出手段、ポンプ出口以降の圧力変化の検出手段及びエレベーターポンプの下降量変化の検出手段の少なくとも1つの検出手段を設け、又は2つ或いは3つの検出手段を組み合せたことを特徴とする粘性流体の移送における残量低減システムであり、ポンプシャフトの上昇、下降スピード変化の検出手段は、ポンプシャフト部に近接スイッチを取り付けて検出したものであり、ポンプ出口以降の圧力変化の検出手段は、ポンプ出口以降部に圧力センサーを取り付けたものであり、エレベーターポンプの下降量変化の検出手段は、エレベーターポンプへ変位センサーを取り付けて検出したものである。   Further, the invention of the system is a system for supplying viscous fluid, wherein at least one of detection means for detecting a change in pump shaft ascent and descent speed, detection means for detecting a change in pressure after the pump outlet, and detection means for detecting a change in the descending amount of the elevator pump is detected. A system for reducing the remaining amount in the transfer of viscous fluid, characterized by providing a means or a combination of two or three detection means. The detection means of the pressure change after the pump outlet is a pressure sensor attached to the part after the pump outlet, and the detection means of the lowering change of the elevator pump is displaced to the elevator pump. It is detected by attaching a sensor.

前記発明において、容器内の粘性流体が少なくなると、ポンプの空打ちによって、ポンプシャフトの上下降スピードに変化を生じる。そこで、ポンプシャフト部に近接スイッチを取付けて、ポンプシャフトの上昇、下降のスピードを検出すると、正常時と、異常時のデータが鮮明に区分されるので、前記異常に移った際には、直ちに切り替えバルブを切り替えて、粘性流体の取り出し容器を、前容器から、後容器に切り替える。このようにすれば、移動変化を検出することで、移送量変化を直ちに捕えることにより、最も簡単な方法で最も正確に現場保存をすることができる。   In the above invention, when the viscous fluid in the container is reduced, the pump shaft is caused to change in the upward / downward speed by the idle driving of the pump. Therefore, when the proximity switch is attached to the pump shaft and the speed of the pump shaft rising and falling is detected, the data at normal time and abnormal time are clearly distinguished. By switching the switching valve, the viscous fluid take-out container is switched from the front container to the rear container. In this way, it is possible to store the change most accurately by the simplest method by capturing the change in the transfer amount immediately by detecting the change in movement.

また前容器に粘性流体の残量が少なくなると、前記ポンプシャフトの上昇下降の不良と相俟って、吐出される粘性流体量に差異を生じ、圧力変化となって現われる。従って、ポンプの吐出圧力変化を検出することによっても残量の少ないことを知ることができる。   Further, when the remaining amount of viscous fluid in the front container decreases, a difference in the amount of viscous fluid to be discharged is produced due to the rise and fall of the pump shaft, which appears as a pressure change. Therefore, it can be known that the remaining amount is small by detecting the change in the discharge pressure of the pump.

前記発明の粘性流体(例えば接着剤)は、例えば自動車のフロントガラスなどの接着剤として使用するのであるが、前記フロントガラスの周縁部へ同一幅で、同一厚さの同一量を塗布できなければならないと共に、全接着剤は同質でなければならない。例えば空気が入ったり、供給流動圧に差異があると、前記塗布幅又は塗布厚さが同一にならない為に、気密はもとより水密を損するおそれがある。そこで、接着作業中に送られる接着剤は同量、同圧、かつ同質でなければならない。   The viscous fluid (for example, adhesive) of the invention is used as an adhesive for, for example, a windshield of an automobile, but if the same amount of the same width and the same thickness cannot be applied to the peripheral portion of the windshield, And all adhesives must be homogeneous. For example, if air enters or there is a difference in the supply flow pressure, the coating width or coating thickness is not the same, so there is a risk that watertightness as well as airtightness may be impaired. Therefore, the adhesive sent during the bonding operation must be the same amount, the same pressure, and the same quality.

然るに移送系は完全に制御されていても、容器(例えばドラム缶)の中に残留する接着剤の量が少なくなると、前記同量、同圧、同質のバランスが崩れ、結果的に同量、同圧、同質を維持することができなくなるおそれがある。   However, even if the transfer system is completely controlled, if the amount of adhesive remaining in the container (for example, a drum can) decreases, the balance of the same amount, the same pressure, and the same quality is lost, and as a result, the same amount, Pressure and homogeneity may not be maintained.

そこでこの発明は、容器内の接着剤量が少なくなって、同量、同圧移送ができなくなる直前に空容器から充実容器に切り替えることにより、移送系における条件の変化を皆無にし、前記同量、同圧、同質条件を維持しようとするものである。   Therefore, the present invention eliminates the change in conditions in the transfer system by switching from an empty container to a full container immediately before the amount of adhesive in the container is reduced and the same amount and pressure cannot be transferred. It is intended to maintain the same pressure and homogeneous conditions.

この発明のような型式の移送ポンプ装置においては、残留する接着剤量が少なくなると、必ずポンプシャフトの上昇、下降スピードの変化、ポンプ出口以降の接着剤の圧力変化、又はエレベーターポンプの下降量の変化を生じるとの知見を得た。   In a transfer pump apparatus of the type such as this invention, whenever the amount of remaining adhesive decreases, the pump shaft rises, the speed of lowering changes, the pressure change of the adhesive after the pump outlet, or the lowering amount of the elevator pump. We have learned that changes will occur.

前記三つの変化は、容器に残留している接着剤の状態により何れが早く現われるか不明であるが、必ず現われるので、前記三つの変化を捕える手段を施しておき、その中で一番早い変化を捕えて、切替バルブを切り替えるようにすれば、前記粘性流体の同量、同圧、同質の条件は確実に確保されることが明らかになった。即ち前記三つの変化は必ず現われるが、容器内底部の状況(例えばドラム缶においては内装袋の状態)により遅速がある。従って最も早い変化により対処すれば、少なくとも切替バルブ以後は正常状態を確実に保っているからである。然し乍ら、前記三つの変化の遅速差異は小さいので、1つの手段だけでも相当の効果を期待できる。   It is unclear which of the three changes will appear earlier depending on the state of the adhesive remaining in the container, but since it always appears, a means for catching the three changes has been applied, and the fastest change among them. It was revealed that the conditions of the same amount, the same pressure, and the same quality of the viscous fluid can be surely secured by switching the switching valve. That is, the above three changes always appear, but there is a slow speed depending on the state of the inner bottom of the container (for example, the state of the inner bag in the drum can). Therefore, if the fastest change is dealt with, the normal state is surely maintained at least after the switching valve. However, since the slow difference between the three changes is small, a considerable effect can be expected with only one means.

例えば、残留接着剤の量が少なくなって、前記三つのセンサーに検知されるのは、少なくともセンサーの設置位置又はセンサーに変化を伝えるもの(例えばポンプのプランジャー)が異常を示す時であるから、既移送分(例えば切替バルブより下流側の移送パイプ中)は、同量、同圧、同質を保っていたことになるからである。   For example, the amount of residual adhesive is reduced, and the three sensors detect it when at least the sensor installation position or the sensor that conveys the change (for example, the pump plunger) is abnormal. This is because the amount already transferred (for example, in the transfer pipe on the downstream side of the switching valve) maintained the same amount, the same pressure, and the same quality.

この発明によれば、粘性流体の移送に際し、ポンプシャフトの上昇、下降、スピードの変化、ポンプ出口以降の圧力変化、又はエレベーターポンプの下降量の変化の何れか1つ(又は全部)を検知して、空になる容器からの粘性流体の移送を中止し、次の容器と切り替えるので、粘性流体の移送量等に変化を及ぼす直前に切り替えることができる。従って、粘性流体は同量、同圧、同質であって、しかも最少残留量で切り替えることができる効果がある。   According to the present invention, when the viscous fluid is transferred, any one (or all) of the pump shaft rising, lowering, speed change, pressure change after the pump outlet, or elevator pump lowering amount is detected. Thus, since the transfer of the viscous fluid from the empty container is stopped and switched to the next container, it is possible to switch immediately before the change in the transfer amount of the viscous fluid or the like. Therefore, the viscous fluid has the same amount, the same pressure, and the same quality, and has an effect that can be switched with the minimum residual amount.

即ち使用状態に悪影響を与えるおそれなく、残留流体(廃棄流体)を最少限に止め得る効果がある。   That is, there is an effect that the residual fluid (waste fluid) can be minimized with no risk of adversely affecting the use state.

この発明は、容器内の粘性流体(以下「接着剤」という)を吸い上げ、押し出す移送装置において、ポンプシャフトの上昇、下降スピードの変化を検出する為に、ポンプシャフト部へ近接スイッチを取り付けると共に、ポンプの出口付近に接着剤の圧力を測定する圧力センサーを設置する。   The present invention attaches a proximity switch to the pump shaft portion in order to detect changes in the pump shaft ascending and descending speed in a transfer device that sucks up and pushes the viscous fluid (hereinafter referred to as “adhesive”) in the container. Install a pressure sensor near the pump outlet to measure the adhesive pressure.

次にエレベーターポンプに変位センサーを取付けて、下降量変化をモニターする。前記各検出器の出力は、夫々コンピュータに入力し、予め測定してある標準数値と比較し、その差が設定値以上になったことを検出した場合には、その出力を切替バルブの駆動部に入力し、切替バルブを空になる方の容器から、充実した容器に切り替え、接着剤の移送を継続する。   Next, attach a displacement sensor to the elevator pump and monitor the change in the descent amount. The output of each detector is input to a computer, compared with a standard value measured in advance, and when it is detected that the difference is equal to or greater than a set value, the output is switched to a switching valve drive unit. And switch the switching valve from the empty container to a full container and continue to transfer the adhesive.

この発明の実施例を図1、2、3、4に基づいて説明すると、台板11上へ、所定の間隔をおいて、リフトチューブ12、12を立設し、リフトチューブ12、12のピストンロッド13、13の上端部へタイバー14を固定して、フォロアプレート16を昇降させるエレベーター15を構成する。前記フォロアプレート16は、二本のタイロッド17、17でタイバー14に支持され、タイバー14と、フォロアプレート16の間に、エアーモータ18及びヒーテッドポンプ19などの送液装置20が設置してある(図1)。   An embodiment of the present invention will be described with reference to FIGS. 1, 2, 3, and 4. Lift tubes 12 and 12 are erected on a base plate 11 at a predetermined interval, and pistons of the lift tubes 12 and 12 are arranged. The tie bar 14 is fixed to the upper ends of the rods 13 and 13 to constitute an elevator 15 that moves the follower plate 16 up and down. The follower plate 16 is supported on the tie bar 14 by two tie rods 17, 17, and a liquid feeding device 20 such as an air motor 18 and a heated pump 19 is installed between the tie bar 14 and the follower plate 16 ( FIG. 1).

前記タイバー14の一側にブラケット10を固定し、このブラケット10へ変位センサー9を固定する。前記変位センサー9は、前記リフトチューブ12の蓋12a面に、例えばアルミテープ(図示してない)を貼着し、前記変位センサー9から発射したレザー光線を前記アルミテープで反射させて、両地点の距離を測定している。従って、その測定値を比較すれば、フォロアプレート16の下降量を正確に測定できるので、該測定値に変化があれば、直ちに検知することができる。   A bracket 10 is fixed to one side of the tie bar 14, and a displacement sensor 9 is fixed to the bracket 10. For example, an aluminum tape (not shown) is attached to the surface of the lid 12a of the lift tube 12, and the laser beam emitted from the displacement sensor 9 is reflected by the aluminum tape, so that the displacement sensor 9 Is measuring the distance. Therefore, if the measured values are compared, the amount of lowering of the follower plate 16 can be accurately measured, so that any change in the measured values can be immediately detected.

次に、ポンプシャフト1に近接スイッチ2を取付ける。このようにすると、ドラム缶3内の残留接着剤が1回分より少なくなると、ポンプは空打ちになるので、ポンプシャフト1の上昇、下降スピードが変化する。この変化を、前記近接スイッチ2で認識し、その出力により空缶の方のバルブ4を閉め、実缶の方のバルブ5を開ける(図5)。   Next, the proximity switch 2 is attached to the pump shaft 1. In this way, when the residual adhesive in the drum can 3 becomes less than one time, the pump is idled, so that the ascending and descending speed of the pump shaft 1 changes. This change is recognized by the proximity switch 2, and the valve 4 for the empty can is closed by the output thereof, and the valve 5 for the actual can is opened (FIG. 5).

またポンプ出口以降部6に圧力センサー7を取り付ける。このようにすると、ドラム缶内の接着剤が少なくなると、吐出接着剤の圧力が低下する。従って圧力低下により生じた出力信号により、切り替え用のバルブ4を閉じ、バルブ5を開けば、自動切り替えができる(図3、5)。   Further, a pressure sensor 7 is attached to the pump outlet subsequent portion 6. If it does in this way, if the adhesive in a drum can decreases, the pressure of a discharge adhesive will fall. Therefore, automatic switching can be performed by closing the switching valve 4 and opening the valve 5 based on the output signal generated by the pressure drop (FIGS. 3 and 5).

前記三つのセンサーは、夫々特性を示すもので、全部又は複数取り付けて、前記センサーの最初の検出により、バルブを自動切り替えすれば、接着剤の残量を最少限に保つことができる。実験の結果によれば、残留接着剤量は、5kg以下となり、大幅に低減したことが認められた。   Each of the three sensors exhibits characteristics. If all or a plurality of sensors are attached and the valve is automatically switched by the first detection of the sensor, the remaining amount of the adhesive can be kept to a minimum. According to the results of the experiment, it was recognized that the amount of residual adhesive was 5 kg or less, which was significantly reduced.

また図5は、この発明のフロー図であって、各バルブの開閉は加圧空気で行っている。各ドラム缶3、3aから送り出される接着剤は、矢示32、32aのように、ヒーティングテフロン(登録商標)ホース33、33aを通過し、バルブ4、又は5を経て、高圧用ボールバルブ34、34aを通過し、定量ポンプ35、35aにより、必要とする箇所へ送られる。図中2、2は、近接スイッチである。   FIG. 5 is a flowchart of the present invention, and each valve is opened and closed with pressurized air. As shown by arrows 32 and 32a, the adhesive sent out from the drums 3 and 3a passes through the heating Teflon (registered trademark) hoses 33 and 33a, passes through the valve 4 or 5, and passes through the high pressure ball valve 34, It passes through 34a and is sent to a required place by the metering pumps 35 and 35a. In the figure, 2 and 2 are proximity switches.

前記において、ドラム缶3の接着剤が空になったならば、ドラム缶3aに切り替えて、接着剤の供給に支障がないようにしている。例えば、No.1のドラム缶3が空になってから、No.2のドラム缶3aに切り替えるけれども、No.1のドラム缶内の接着剤の残量が少なくなると、空気が入り、接着に支障が生じるおそれがあるので、前記のように、空気が入る直前に切り替えることが好ましい。そこで空気の入る直前の時機を正確に検出すべく研究し、この発明を完成したものである。   In the above, when the adhesive of the drum can 3 becomes empty, it is switched to the drum can 3a so that the supply of the adhesive is not hindered. For example, no. No. 1 drum can 3 is empty, no. No. 2 drum can 3a. When the remaining amount of the adhesive in one drum can decreases, air enters and there is a possibility that the adhesion may be hindered. Therefore, as described above, switching is preferably performed immediately before the air enters. Thus, the present invention has been completed by conducting research to accurately detect the timing immediately before the air enters.

前記実施例におけるヒーテッドポンプ19の動作を図4(a)(b)について説明すると、ロッド21が矢示22のように、図4(b)→(a)に上昇すると(エアー圧により上昇、図示してない)、チェックバルブ23は閉から開となって、ロッド21からロッド24を引いた体積と同じ量の材料が矢示25のように吐出される。同様にロッド24からプランジャーロッド26を引いた体積と同じ量の材料が下室27へ矢示28のように入ることになる。この場合にチェックバルブ29は閉から開になる。従って、ロッド21の昇降により、接着剤などの材料を間欠的に給送することができる。   The operation of the heated pump 19 in the above embodiment will be described with reference to FIGS. 4 (a) and 4 (b). When the rod 21 is raised from FIG. The check valve 23 is opened from the closed state (not shown), and the same amount of material as the volume obtained by pulling the rod 24 from the rod 21 is discharged as indicated by an arrow 25. Similarly, the same amount of material as the volume obtained by pulling the plunger rod 26 from the rod 24 enters the lower chamber 27 as shown by an arrow 28. In this case, the check valve 29 is opened from the closed state. Therefore, materials such as an adhesive can be intermittently fed by raising and lowering the rod 21.

前記において、ロッド21、プランジャーロッド26は、矢示22、22aのように昇降する。図中30は、プランジャーロッド26の下端に固定したプライマープレートで、プランジャーロッド26の上昇時に、弁座31の下面を塞ぐようにしてある。   In the above, the rod 21 and the plunger rod 26 move up and down as indicated by arrows 22 and 22a. In the figure, reference numeral 30 denotes a primer plate fixed to the lower end of the plunger rod 26 so as to close the lower surface of the valve seat 31 when the plunger rod 26 is raised.
