Description

本発明は、塗布剤または充填剤等のシーラを吐出筒の先端の吐出口から吐出させるシーラガンであって、シーラの吐出を停止させたときに吐出筒の先端の吐出口部に生じてくるシーラの液だれを除去・消失せしめる液だれ防止装置を装備せしめているシーラガンについての改良に関する。   The present invention relates to a sealer gun that discharges a sealer such as a coating agent or a filler from a discharge port at the tip of a discharge cylinder, and is generated at a discharge port portion at the tip of the discharge cylinder when discharge of the sealer is stopped. The present invention relates to an improvement on a sealer gun equipped with a dripping prevention device that removes and eliminates dripping of water.

さらに具体的にいえば、筒状に形成して基端側に把持グリップを具備せしめたボディの先端部に、先端側を小径のノズルに形成した吐出筒を接続し、ボディの内部には、シーラを吐出筒に導く導入管と、その導入管と吐出筒との連通を断・接する弁機構とを設け、その弁機構を、把持グリップに並列させてボディに軸支した握りレバーに対し、該レバーの握り込みで開弁し、握り込みの解放による復元回動で閉弁するよう連繋したシーラガンにおいて、ボディには、握りレバーの回動動作によりピストンがケーシングに対し出入作動して吸引・吐出のポンプ作動を行うポンプ装置を付設し、そのポンプ装置の吸引・吐出口を、シーラガンの吐出筒の内腔で、吐出口の近傍に配位して、握りレバーを放してシーラの吐出を停止したときに、吐出筒の吐出口付近のシーラをポンプ装置の拡縮室内に吸引して消失せしめるようにした液だれ防止装置を装備せしめているシーラガンについての改良に関するものである。   More specifically, a discharge cylinder formed with a small diameter nozzle on the distal end side is connected to the distal end portion of the body that is formed in a cylindrical shape and has a grip grip on the proximal end side, and inside the body, An introduction pipe that guides the sealer to the discharge cylinder and a valve mechanism that disconnects and contacts the introduction pipe and the discharge cylinder are provided. In the sealer gun, which is opened by grasping the lever and linked to close by restoring rotation by releasing the grasp, the piston is moved in and out of the casing by the turning operation of the grasping lever. A pump device that performs the pump operation of the discharge is attached, and the suction / discharge port of the pump device is positioned in the vicinity of the discharge port in the lumen of the discharge cylinder of the sealer gun, and the grip lever is released to discharge the sealer. Discharge when stopped Liquid sealer of discharge near the port and so allowed to disappear by sucking the scaling chamber of the pump device to an improvement of the Shiragan that allowed equipped with whom prevention device.

塗布剤・充填剤などを液材料としたシーラを、構造体の隙間・間隙に、塗布・充填する作業に用いられるシーラガンは、通常、図1に示しているように、基端側に把持グリップ1を有する中空筒体の銃身状に形成したボディaの先端部に、先端側を小径のノズル部20に形成した吐出筒2の基端側を接続し、ボディaの内部には、導入管3から供給されてくるシーラを先端部の吐出筒2に導く管路30と、その管路30と吐出筒2との連通を断・接する弁口40と弁座口41とからなる弁機構4とを設け、その弁機構4と、ボディaの把持グリップ1に並列させてボディaに軸支した握りレバー5とを、その握りレバー5を把持グリップ1と共に握り込む作動で弁機構4が開弁し、その握りレバー5の握り込みの解放作動でその握りレバー5が復元バネ50により復元回動する作動で弁機構4の閉弁が行われるよう連繋機構51を介し連繋し、握りレバー5を把持グリップ1とともに握り込むと、弁機構4が開弁して導入管3から供給されてくるシーラが、管路30を経て吐出筒2に導かれて、それのノズル部20の先端の吐出口20aから吐出され、握りレバー5の握り込みを放すと、弁機構4が閉弁して、シーラの吐出が停止するように構成してある。   As shown in FIG. 1, a sealer gun used for applying and filling a sealer made of a liquid material such as a coating agent / filler into a gap / gap of a structure body usually has a grip grip on the base end side. 1 is connected to a distal end portion of a body a formed in a barrel shape of a hollow cylinder 1 having a distal end side of a discharge cylinder 2 formed in a nozzle portion 20 having a small diameter. 3 is a valve mechanism 4 including a pipe line 30 that guides the sealer supplied from the pipe 3 to the discharge cylinder 2 at the tip, and a valve port 40 and a valve seat port 41 that disconnect and connect the pipe line 30 and the discharge cylinder 2. The valve mechanism 4 is opened by the operation of gripping the grip lever 5 together with the grip grip 1 with the valve mechanism 4 and the grip lever 5 pivotally supported on the body a in parallel with the grip grip 1 of the body a. The grip lever 5 is released when the grip lever 5 is released. When the gripping lever 5 is gripped together with the gripping grip 1 so that the valve mechanism 4 is closed by an operation of rotating by the restoring spring 50 and the valve mechanism 4 is closed, the valve mechanism 4 is opened to introduce the introduction pipe. When the sealer supplied from 3 is guided to the discharge cylinder 2 through the pipe line 30 and discharged from the discharge port 20a at the tip of the nozzle portion 20, and the grip lever 5 is released, the valve mechanism 4 is released. Is closed so that the discharge of the sealer is stopped.

このシーラガンAは、握りレバー5の握り込みを放して、シーラの吐出を停止させたとき、弁機構4より下流側においてシーラガンAの機内に残留したシーラが、導入管3から導入されるときに与えられている圧力により、吐出筒2の先端の吐出口20aから押し出されてくるようになる。   When this sealer gun A is released from the sealer by releasing the grip lever 5, the sealer remaining in the machine of the sealer gun A is introduced from the introduction pipe 3 on the downstream side of the valve mechanism 4. Due to the applied pressure, the discharge tube 2 is pushed out from the discharge port 20a.

そして、シーラガンAの器内から吐出口を介して押し出されるシーラSは、粘性を具備して付着性と凝集性が大きい性状のものであることから、吐出筒2のノズル20先端の吐出口20aから離れずに、その吐出口の周縁に付着して、つらら状に垂れ下がり、液だれの現象を呈するようになる。   The sealer S pushed out from the inside of the sealer gun A through the discharge port has a viscosity and has a high adhesion and agglomeration. Therefore, the discharge port 20a at the tip of the nozzle 20 of the discharge cylinder 2 is used. Without leaving, it adheres to the periphery of the discharge port, hangs down in an icicle shape, and exhibits a phenomenon of dripping.

このシーラの吐出を弁機構4の作動により停止させたときに、吐出筒1の先端の吐出口20aの周辺に付着して垂れ下がるシーラの液だれは、放置しておくと、外気に曝されることで、次に塗布作業・充填作業を行うときには、正常に使用できない性状のものに変性する性状のものであることから、シーラの吐出を停止させたときに、その直後に、吐出筒2の先端から拭き取って廃棄する処理を行っている。このことから、シーラガンAには、液材料のシーラの吐出を停止させる度ごとに、生じてくる液だれを拭き取る作業を行わなければならないことで、塗布・充填作業の作業性を悪くし、また液だれを廃棄することで、シーラの損失を招いている問題がある。   When the discharge of the sealer is stopped by the operation of the valve mechanism 4, the dripping of the sealer that adheres to the periphery of the discharge port 20 a at the tip of the discharge cylinder 1 and hangs down is exposed to the outside air. Thus, the next time when the coating operation / filling operation is performed, the property is changed to a property that cannot be normally used. Therefore, immediately after the discharge of the sealer is stopped, The tip is wiped off and discarded. For this reason, the sealer gun A has to perform the work of wiping off the generated liquid every time the discharge of the sealer of the liquid material is stopped. There is a problem of causing the loss of the sealer by discarding the dripping.

シーラガンAに組み付け装備せしめる液だれの防止装置Bは、このシーラガンAに、シーラの吐出を停止させる度ごとに生じてくる液だれを消失せしめるためのものである。   The liquid dripping prevention device B assembled and installed in the sealer gun A is for causing the liquid dripping that occurs every time the sealer gun A stops the discharge of the sealer to disappear.

このシーラガンAに組み付け装備せしめる液だれ防止装置Bは、図2に示しているように、シーラガンAの本体を構成するボディaに、内部空間をシリンダ状に形成したケーシング60と、そのケーシング60の後面側から摺動自在に嵌合するピストン61と、そのケーシング60の前端側に装着する吸引ブロック62と、その吸引ブロック62に設けた吸引・吐出口63に接続する吸引・吐出パイプ64とからなるポンプ装置Pを、それのピストン61のケーシング60に対する出入作動により、吸引ブロック62の後壁面とピストン61の前端面との間に形成される拡縮室pが拡縮して、吸引・吐出口63を介し吸引と吐出を行うように構成して組み付ける。そして、このポンプ装置Pを、それのピストン61の往動・復動による吸引・吐出の作動を、握りレバー5を握り込んで、シーラの吐出が行われるようにしたときには、ピストン61が押し込まれて吐出作動を行い、握りレバー5の握り込みが解放されて握りレバー5が復元バネ50により復元回動するときには、ピストン61が引き出されてケーシング60内の拡縮室pの内容積を拡張して吸引作動を行うように、握りレバー5の回動作動に対し連動連繋させ、この握りレバー5を放してシーラの吐出を停止させたときに行われる吸引作動で液だれのシーラSを拡縮室pに吸引させることで液だれ防止装置Bを構成するようにしている。   As shown in FIG. 2, a dripping prevention device B assembled and installed in the sealer gun A includes a casing 60 in which an inner space is formed in a cylinder shape in a body a constituting the main body of the sealer gun A, and the casing 60. From a piston 61 slidably fitted from the rear side, a suction block 62 attached to the front end side of the casing 60, and a suction / discharge pipe 64 connected to a suction / discharge port 63 provided in the suction block 62 The expansion / contraction chamber p formed between the rear wall surface of the suction block 62 and the front end surface of the piston 61 is expanded / reduced by an operation of moving the piston 61 into and out of the casing 60 of the piston 61, and the suction / discharge port 63. It is constructed and assembled so as to perform suction and discharge via When the pump device P is operated to perform suction / discharge operation by the forward / backward movement of the piston 61 so that the grip lever 5 is grasped and the sealer is discharged, the piston 61 is pushed in. When the grip lever 5 is released and the grip lever 5 is restored and rotated by the restoring spring 50, the piston 61 is pulled out to expand the internal volume of the expansion / contraction chamber p in the casing 60. In order to perform the suction operation, the interlocking operation is linked to the rotation operation of the grip lever 5, and when the release of the sealer is stopped by releasing the grip lever 5, the liquid sealer S is expanded and contracted by the suction operation. The liquid dripping prevention device B is configured by sucking.

この連動連繋は、図2に示しているシーラガンAの液だれ防止装置Bにあっては、ポンプ装置Pのピストン61を、弁機構4の弁軸42の先端部に、一体的に連続させて設けておいて、握りレバー5の握り込みにより、弁軸42の後端側に連続させて形成せるシャフト7の周面に設けたボビン状の係止部材51aと、握りレバー5の上端側に形設した角状の係合突起51bとからなる連繋機構51を介し弁軸42が、前方(図2において左方)に押し出されて、その弁軸42に設けた弁座口41が弁口40と対向する位置に動き、弁機構4を開弁した状態としたときに、弁軸42の先端側に設けたピストン61が、ケーシング60内に押し込まれて、図3の(1)にあるように、ケーシング60の吸引ブロック62の前面とピストン61の前端壁とで形成する拡縮室pを押し縮めて吐出作動を行い、握りレバー5の握り込みを解放して、握りレバー5を復元バネ50により復元回動させ同時に弁軸42を後方(図2において右方)に引き戻し弁軸42に設けた弁座口41を弁口40から離れた位置に動かして弁機構4を閉弁状態とするときは、図3の(2)、(3)、(4)に示している如く、弁軸42とともにピストン61がケーシング60から引き出されるように動いて、ケーシング60内の拡縮室pを拡張させて吸引作動を行うようにして、握りレバー5との連動・連繋を行わせている。   In the interlocking device B of the sealer gun A shown in FIG. 2, this interlocking connection is achieved by continuously connecting the piston 61 of the pump device P to the tip of the valve shaft 42 of the valve mechanism 4. The bobbin-shaped locking member 51a provided on the peripheral surface of the shaft 7 formed continuously by the rear end side of the valve shaft 42 by the grip lever 5 and the upper end side of the grip lever 5 are provided. The valve shaft 42 is pushed forward (to the left in FIG. 2) via a connecting mechanism 51 formed by the formed angular engagement protrusions 51b, and the valve seat port 41 provided on the valve shaft 42 becomes the valve port. When the valve mechanism 4 is moved to a position facing the valve 40 and the valve mechanism 4 is opened, the piston 61 provided on the distal end side of the valve shaft 42 is pushed into the casing 60 and is in (1) of FIG. As shown, the front surface of the suction block 62 of the casing 60 and the front of the piston 61 The expansion / contraction chamber p formed by the wall is pushed and contracted to perform the discharge operation, the grip lever 5 is released, the grip lever 5 is restored by the restoring spring 50, and the valve shaft 42 is moved backward (in FIG. 2). When the valve mechanism 41 is moved to a position away from the valve port 40 by moving the valve seat 41 provided on the pull-back valve shaft 42 to the right) to close the valve mechanism 4, (2), (3), ( 4) As shown in FIG. 4, the piston 61 moves with the valve shaft 42 so as to be pulled out from the casing 60, and the expansion / contraction chamber p in the casing 60 is expanded to perform the suction operation, and the interlocking with the grip lever 5 is performed.・ It is connected.

そして、このポンプ装置Pのケーシング60内の拡縮室pと連通する吸引・吐出パイプ64の先端開口は、シーラガンAの吐出筒2の内部で、ノズル部20先端の吐出口20aの近傍位置に臨むように配位しておき、これにより、握りレバー5の握り込みを解放して、シーラの吐出を停止したときに、ポンプ装置Pが吸引作動を行って、吐出筒2のノズル20の先端部位に付着して垂れ下がるシーラの液だれを、吐出筒2のノズル部20先端の吐出口20aから、逆に吐出筒2内に引き込み、拡張していくポンプ装置Pのケーシング60内部の拡縮室p内に吸引して、ノズル20先端部の周辺から除去・消失させるようにしている。   The tip opening of the suction / discharge pipe 64 communicating with the expansion / contraction chamber p in the casing 60 of the pump device P faces the position near the discharge port 20a at the tip of the nozzle portion 20 inside the discharge cylinder 2 of the sealer gun A. Thus, when the grip lever 5 is released and the discharge of the sealer is stopped, the pump device P performs the suction operation, and the tip portion of the nozzle 20 of the discharge cylinder 2 In the expansion / contraction chamber p inside the casing 60 of the pump device P, the liquid of the sealer that adheres and hangs down is drawn from the discharge port 20a at the tip of the nozzle portion 20 of the discharge cylinder 2 into the discharge cylinder 2 and expanded. So as to be removed / disappeared from the periphery of the tip of the nozzle 20.

このように液だれ防止装置Bを装備せしめたシーラガンAは、シーラの吐出を停止させたときに、吐出筒2の先端に付着して垂れ下がるシーラを、吐出筒2の内部から吸引・吐出パイプ64を経てポンプ装置Pの拡縮室p内に引き込むことで消失させるようにすることから、吐出筒2及び吸引・吐出パイプ64の内部に、外気との接触により変性して固化したシーラが存在してくるようになって、吐出筒2の先端の吐出口20aからのシーラの吐出に詰まりが生ずるようになるので、吐出筒2内の清掃を度々行わなければならない。しかも、シーラガンAの先端の吐出筒2は、通常、ボディaの先端部に対し圧入嵌合により連結させてボディaに一体的に接続した状態に装設してあることから、吐出筒2内部の清掃は外部から行わなければならず、その清掃作業を厄介なものとしているので、その清掃作業のために作業性を悪くする問題を生ぜしめている。   The sealer gun A equipped with the dripping prevention device B in this manner causes the sealer that adheres to the tip of the discharge cylinder 2 and hangs down from the inside of the discharge cylinder 2 when the discharge of the sealer is stopped. The sealer that is denatured and solidified by contact with the outside air exists in the discharge cylinder 2 and the suction / discharge pipe 64 in order to be eliminated by being drawn into the expansion / contraction chamber p of the pump device P. As a result, the discharge of the sealer from the discharge port 20a at the tip of the discharge cylinder 2 becomes clogged, so that the inside of the discharge cylinder 2 must be frequently cleaned. Moreover, since the discharge cylinder 2 at the tip of the sealer gun A is usually connected to the tip of the body a by press-fitting and connected integrally to the body a, This cleaning work must be carried out from the outside, which makes the cleaning work troublesome, which causes a problem of deteriorating workability due to the cleaning work.

本発明において解決しようとする課題は、シーラの吐出を停止させたときに、吐出筒の先端に付着して垂れ下がるように生じてくるシーラの液だれを、ボディに組み付けたポンプ装置の吸引作動で、吐出筒内を経てポンプ装置の拡縮室に吸引せしめて消失・除去せしめるようにしているシーラガンにおいて、詰まり防止のために要する吐出筒の内部の清掃作業が、適確迅速に行えるようにする手段を構成する点にある。   The problem to be solved in the present invention is the suction operation of the pump device assembled to the body, which causes the dripping of the sealer that is caused to adhere to the tip of the discharge cylinder and hang down when the discharge of the sealer is stopped. In the sealer gun, which is sucked into the expansion / contraction chamber of the pump device through the discharge cylinder and disappeared / removed, the means for enabling the cleaning operation inside the discharge cylinder required for preventing clogging to be performed quickly and accurately It is in the point which constitutes.
