Description

本発明は自動車ボディなどの塗装に用いる塗装ガンに関し、詳しくは、ガン本体の長手方向における先端部に向き(面姿勢)が互いに異なる複数のノズル取付面部を隣り合わせ状態で形成し、塗料ノズルを各ノズル取付面部に対する立姿勢状態で取り付けるノズル固定部を前記ノズル取付面部の夫々に設け、取り付け状態にある塗料ノズルの塗料流入口に対して連通状態となる塗料送出口を前記ノズル固定部の夫々に設けてある特に高粘度材料用などとして好適な塗装ガンに関する。   The present invention relates to a coating gun used for painting an automobile body or the like. Specifically, a plurality of nozzle mounting surface portions having different orientations (surface postures) are formed adjacent to each other at the distal end portion in the longitudinal direction of the gun body. A nozzle fixing portion to be mounted in a standing posture with respect to the nozzle mounting surface portion is provided in each of the nozzle mounting surface portions, and a paint delivery port that is in communication with the paint inlet of the paint nozzle in the attached state is provided in each of the nozzle fixing portions. The present invention relates to a coating gun that is particularly suitable for high viscosity materials.

従来、この種の塗装ガンとしては図4に示すものが知れられており、この塗装ガンでは 、向きが互いに異なる3つのノズル取付面部4a〜4cを隣り合わせ状態でガン本体1の長手方向における先端部1aに形成し、これら3つのノズル取付面部4a〜4cの夫々に上記の如き塗料送出口7を備える各1ずつのノズル固定部5を設けていた。 Conventionally, as this kind of paint gun, the one shown in FIG. 4 is known, and in this paint gun, the front end portion in the longitudinal direction of the gun body 1 with the three nozzle mounting surface portions 4a to 4c having different orientations adjacent to each other. Each of these three nozzle mounting surface portions 4a to 4c is provided with one nozzle fixing portion 5 provided with the paint delivery port 7 as described above.

つまり、この塗装ガンを用いれば、3つのノズル取付面部4a〜4cのうち、いずれのノズル取付面部4a〜4cのノズル固定部5に取り付けた塗料ノズル2を用いて塗装を行うかを選択することにより、塗装ガンを保持する塗装ロボットや作業者に無理な姿勢を強いることなく被塗物の各塗装部位を容易かつ能率良く塗装することが可能になる。   That is, if this coating gun is used, it is selected whether the coating is performed using the coating nozzle 2 attached to the nozzle fixing portion 5 of any of the nozzle mounting surface portions 4a to 4c among the three nozzle mounting surface portions 4a to 4c. Thus, it becomes possible to easily and efficiently coat each painting portion of the object to be coated without forcing the posture of the painting robot or the operator holding the painting gun.

あるいはまた、取り付けた3つの塗料ノズル2の中から塗料の噴出パターンなどの面で被塗物の各塗装部位に適した種類の塗料ノズル2を適宜容易に使い分けすることが可能になる。   Alternatively, among the three paint nozzles 2 attached, the types of paint nozzles 2 suitable for each application site of the object to be coated can be used appropriately and easily in terms of the spray pattern of the paint.

そしてまた、1つの塗料ノズル2を取り付けただけの一般の塗装ガンを塗装部位別に複数装備するのに比べ設備コスト面などでも有利することができる。   In addition, it is advantageous in terms of equipment cost as compared with the case where a plurality of general paint guns each having only one paint nozzle 2 attached are provided for each paint site.

http://www.sca-schucker.de/en/products/application-components/nozzles.html (2009/11/18)http://www.sca-schucker.de/en/products/application-components/nozzles.html (2009/11/18)

しかし、上記した従来の塗装ガンでは、例えば、塗料ノズル2の種類を優先して、3つのノズル取付面部4a〜4cの塗料ノズル2のうち塗装部位に適した種類の塗料ノズル2を選択した場合、その塗装部位によっては塗装ガンを保持する塗装ロボットや作業者に無理な姿勢を強いる状態を招く問題があった。   However, in the above-described conventional paint gun, for example, the type of paint nozzle 2 is given priority, and the type of paint nozzle 2 suitable for the painting site is selected from the paint nozzles 2 of the three nozzle mounting surface portions 4a to 4c. Depending on the part of the paint, there has been a problem in that a painting robot that holds a paint gun or an operator is forced to take an unreasonable posture.

また逆に、塗料ノズル2の向きを優先して、3つのノズル取付面部4a〜4cの塗料ノズル2のうち塗装部位に適した向きのノズル取付面部4a〜4cにおける塗料ノズル2を選択した場合、塗装ロボットや作業者に無理な姿勢を強いることは回避できたとしても、塗装部位に対する塗料ノズル2の種類が不適切となり、却って塗装品質の低下や塗装能率の低下を招くなどの問題があった。   On the other hand, when the direction of the paint nozzle 2 is given priority and the paint nozzle 2 in the nozzle attachment surface portions 4a to 4c of the orientation suitable for the painting part is selected from the paint nozzles 2 of the three nozzle attachment surface portions 4a to 4c, Even though it was possible to avoid forcing the painting robot or operator to take an unreasonable posture, the type of the paint nozzle 2 for the painting site became inappropriate, and on the contrary, there were problems such as lowering the painting quality and lowering the painting efficiency. .

この実情に鑑み、本発明の主たる課題は、上記の如き問題を効果的に解消できる機能性及び利便性に一層優れた塗装ガンを提供する点にあり、また併せて、複数種の塗料を用いる塗装条件に対しても高い利便性を発揮できるようにする点にある。   In view of this situation, the main problem of the present invention is to provide a coating gun with more excellent functionality and convenience that can effectively solve the above problems, and in addition, a plurality of types of paints are used. It is in the point which can demonstrate high convenience also with respect to coating conditions.

The paint nozzle can be attached and fixed to the nozzle fixing portion in the state where it is positioned at the nozzle fixing portion.

従って、ノズル固定部に対する塗料ノズルの取り付けを容易にすることができ、この点でも利便性に優れた塗装ガンにすることができる。   Therefore, it is possible to easily attach the paint nozzle to the nozzle fixing portion, and in this respect as well, it is possible to make the paint gun excellent in convenience.

なお、この構成の実施においてスライド案内手段は、案内対象の塗料ノズルがノズル取付面部から脱落するのを防止する脱落防止機能も備える構造にしておくのが望ましい。   In the implementation of this configuration, it is desirable that the slide guide means has a structure that also has a drop-off preventing function for preventing the paint nozzle to be guided from dropping from the nozzle mounting surface portion.

The base end 1b in the longitudinal direction of the gun body 1 is provided with a mounting flange 3 for the arm A of the painting robot.

つまり、この塗装ガンGは、それを取り付けた塗装ロボットのアームAの動作によりガン本体先端部1aの塗料ノズル2を被塗物(例えば自動車ボディ)の各塗装部位に対して所定の塗装向き及び所定の離間距離となる状態にし、その状態で塗料ノズル2からの塗料噴出により各塗装部位(例えば、自動車ボディのアンダーコート部やシーリング部など)を順次に塗装する。   That is, the coating gun G moves the coating nozzle 2 of the gun body tip 1a to each coating portion of the object to be coated (for example, an automobile body) by a movement of the arm A of the coating robot to which the coating gun is attached. In a state where a predetermined separation distance is reached, each coating portion (for example, an undercoat portion or a sealing portion of an automobile body) is sequentially coated by spraying paint from the paint nozzle 2.

図2に示す如く、ガン本体先端部1aには、その先端部1aにおいてガン本体1の長手方向軸芯Xに直交する軸芯Qを想定した場合、その直交軸芯Q周りでの向き(面姿勢)が互いに異なる2つのノズル取付面部4a,4bを直交軸芯Q周りの周方向に並べて隣り合わせ状態に形成にしてある。   As shown in FIG. 2, when assuming an axis Q that is orthogonal to the longitudinal axis X of the gun body 1 at the tip 1a, the gun body tip 1a is oriented around the orthogonal axis Q (surface). Two nozzle mounting surface portions 4a and 4b having different postures are arranged side by side in the circumferential direction around the orthogonal axis Q and are formed adjacent to each other.

なお、本例では2つのノズル取付面部4a,4bの一方はガン本体1の長手方向軸芯Xに対して直交する向きにし、他方はガン本体1の長手方向軸芯Xに対して45°の傾斜角を有する向きにしてある。   In this example, one of the two nozzle mounting surface portions 4a and 4b is oriented perpendicular to the longitudinal axis X of the gun body 1, and the other is 45 ° with respect to the longitudinal axis X of the gun body 1. The orientation has an inclination angle.

また、これらノズル取付面部4a,4bには夫々、塗料ノズル2を取り付ける各2つのノズル固定部5a,5bを上記直交軸芯Qの方向(換言すれば、各ノズル取付面部4a,4bの面方向のうちでノズル取付面部4a,4bどうしの並び方向に対して直交する方向)に列状に並べて設け、これらノズル固定部5a,5bには、そこに取り付けた塗料ノズル2の塗料流入口6に対して連通状態となる塗料送出口7を個別に設けてある。   The nozzle mounting surface portions 4a and 4b are respectively provided with two nozzle fixing portions 5a and 5b for mounting the paint nozzle 2 in the direction of the orthogonal axis Q (in other words, the surface direction of the nozzle mounting surface portions 4a and 4b). The nozzle mounting surface portions 4a and 4b are arranged in a row in a direction orthogonal to the direction in which the nozzle mounting surface portions 4a and 4b are aligned, and these nozzle fixing portions 5a and 5b are connected to the paint inlet 6 of the paint nozzle 2 attached thereto. On the other hand, the paint delivery port 7 which is in a communication state is provided individually.

各ノズル固定部5a,5bに対する塗料ノズル2の取り付けは、先ず、各ノズル取付面部4a,4bの2つのノズル固定部5a,5bにわたらせる状態で各ノズル取付面部4a,4bの全幅にわたらせて各ノズル取付面部4a,4bに形成してある溝部8に各塗料ノズル2の共通ベース部9を嵌め込み、これにより、塗料ノズル2をノズル取付面部4a,4bに対して立姿勢状態(即ち、塗料ノズル2の塗料噴出口10が塗装ガンGの先方を向く状態)で仮配置する。   The paint nozzle 2 is attached to the nozzle fixing portions 5a and 5b by first extending over the entire width of the nozzle mounting surface portions 4a and 4b in a state where the nozzle mounting surface portions 4a and 4b extend over the two nozzle fixing portions 5a and 5b. The common base portion 9 of each paint nozzle 2 is fitted into the groove portion 8 formed in each nozzle mounting surface portion 4a, 4b, whereby the paint nozzle 2 is in a standing posture state (that is, paint) with respect to the nozzle mounting surface portions 4a, 4b. Temporary placement is performed in a state in which the paint outlet 10 of the nozzle 2 faces the tip of the paint gun G).

また、この仮配置状態において必要に応じ、塗料ノズル2を溝部8による案内下で溝部8に沿ってスライド移動させることにより、塗料ノズル2の共通ベース部9に形成してある塗料流入口6と溝部8の底面に形成してある各ノズル固定部5a,5bの塗料送出口7とが合致し、かつ、同じく塗料ノズル2の共通ベース部9に形成してある取付孔11と同じく溝部8の底面に形成してある取付ネジ孔12とが合致する状態に立姿勢状態の塗料ノズル2を位置調整する。   Further, in this temporary arrangement state, if necessary, the paint nozzle 2 is slid along the groove portion 8 under the guidance of the groove portion 8, whereby the paint inlet 6 formed in the common base portion 9 of the paint nozzle 2 and The nozzle feed portions 7 of the nozzle fixing portions 5a and 5b formed on the bottom surface of the groove portion 8 coincide with each other, and the groove portion 8 has the same mounting hole 11 as that formed in the common base portion 9 of the paint nozzle 2. The position of the paint nozzle 2 in the standing posture is adjusted so that the mounting screw hole 12 formed on the bottom surface matches.

そして、この状態において塗料ノズル2における共通ベース部9の取付孔11を通じそれに合致する溝部8の取付ネジ孔12に取付ネジ13をネジ込むことで、塗料ノズル2を各ノズル固定部5a,5bに取り付け固定する。   In this state, the coating nozzle 2 is screwed into the nozzle fixing portions 5a and 5b by screwing the mounting screws 13 through the mounting holes 11 of the common base portion 9 in the coating nozzle 2 and into the mounting screw holes 12 of the groove portion 8 corresponding thereto. Install and fix.

つまり、上記溝部8は、ノズル固定部5a,5bに対する塗料ノズル2の取り付けにおいて、同一のノズル取付面部4a,4bにおける複数のノズル固定部5a,5bどうしにわたる塗料ノズル2のスライド移動を案内するスライド案内手段として機能するものである。   That is, the groove 8 slides to guide the sliding movement of the paint nozzle 2 across the plurality of nozzle fixing portions 5a, 5b on the same nozzle mounting surface portion 4a, 4b when the paint nozzle 2 is attached to the nozzle fixing portions 5a, 5b. It functions as a guide means.

各ノズル取付面部4a,4bのノズル固定部5a,5bに塗料ノズル2を取り付けるのに基本的に、各塗料ノズル2は2つのノズル取付面部4a,4bのうち担当の塗装部位を塗装するのに向きなどの位置関係が有利となるノズル取付面部4a,4bを選択して取り付け、また、同一のノズル取付面部4a,4bにおける2つのノズル固定部5a,5bには、塗料噴出パターンの断面形状や寸法あるいはノズル立姿勢中心軸芯q周りでの姿勢などが互いに異なる異種の塗料ノズル2で各々の担当塗装部位の塗装に適合した種類の塗料ノズル2を取り付ける。   In order to attach the paint nozzle 2 to the nozzle fixing portions 5a and 5b of the nozzle attachment surface portions 4a and 4b, basically, each paint nozzle 2 applies the coating portion in charge of the two nozzle attachment surface portions 4a and 4b. The nozzle mounting surface portions 4a and 4b that are advantageous in the positional relationship such as the orientation are selected and mounted, and the two nozzle fixing portions 5a and 5b in the same nozzle mounting surface portions 4a and 4b are provided with a cross-sectional shape of a paint ejection pattern, The different types of paint nozzles 2 having different dimensions and postures around the central axis q of the nozzle standing posture and the like are adapted to the painting of each assigned paint site.

異種の塗料ノズル2としては、図2に示す如く、塗料噴出パターンがノズル立姿勢中心軸芯qと同芯の円錐形状である丸ノズル2a、塗料噴出口10が2つのノズル固定部5a,5bの並び方向を長辺方向とするスリット状である横向き平ノズル2b、塗料噴出口10が2つのノズル固定部5a,5bの並び方向を短辺方向とするスリット状である縦向き平ノズル2c、また、塗料噴出口10の寸法や噴出塗料の拡がり角度が互いに異なるものなど、種々のものがある。   As shown in FIG. 2, the different types of paint nozzles 2 include a round nozzle 2a having a paint spraying pattern concentric with the center axis q of the nozzle standing posture, and a paint outlet 10 having two nozzle fixing portions 5a and 5b. A horizontal flat nozzle 2b having a slit shape in which the arrangement direction of the two nozzle fixing portions 5a and 5b is a short side direction. Moreover, there are various types such as those in which the size of the paint jet port 10 and the spread angle of the jet paint differ from each other.

これらノズル固定部5a,5bへの取り付けが予定される複数種の塗料ノズル2にはいずれも前記共通ベース部9を設けてあり、各ノズル取付面部4a,4bのいずれのノズル固定部5a,5bに対しても適宜に取り付け換えできるようにしてある。   The plurality of types of paint nozzles 2 scheduled to be attached to the nozzle fixing portions 5a and 5b are all provided with the common base portion 9, and any nozzle fixing portions 5a and 5b of the nozzle attachment surface portions 4a and 4b are provided. Also, it is possible to replace it appropriately.

ガン本体1はその基端部1bに設けたスイベルジョイント部14により、先端部1aの側を基端部1bに対してガン本体1の長手方向軸芯X周りで回転動作させ得る構造にしてあり、塗装ロボットのアームAの動作と連係させてガン本体1の先端部1aの側を基端部1bに対し回転動作させることで、各ノズル取付面部4a,4bのノズル固定部5a,5bに取り付けた塗料ノズル2を塗装部位との位置関係に応じてガン本体長手方向軸芯X周りで向き変更させ得るようにしてある。   The gun body 1 is structured so that the swivel joint part 14 provided at the base end 1b can rotate the distal end 1a side around the longitudinal axis X of the gun body 1 with respect to the base end 1b. The gun body 1 is attached to the nozzle fixing portions 5a and 5b of the nozzle mounting surface portions 4a and 4b by rotating the distal end portion 1a side of the gun body 1 relative to the base end portion 1b in conjunction with the operation of the arm A of the painting robot. The direction of the paint nozzle 2 can be changed around the longitudinal axis X of the gun body in accordance with the positional relationship with the paint site.

つまり、このスイベルジョイント部14は、複数のノズル取付面部4a,4bを備えるガン本体1の長手方向先端部1aを基端部1bに対してガン本体1の長手方向軸芯X周りで回転させて向き変更させる先端向き変更手段として機能する。   That is, the swivel joint part 14 rotates the longitudinal tip 1a of the gun body 1 having the plurality of nozzle mounting surface parts 4a and 4b around the longitudinal axis X of the gun body 1 with respect to the base end 1b. It functions as a tip direction changing means for changing the direction.

スイベルジョイント部14には、ガン本体1に対して2種の塗料Ta,Tbを各別に供給する2本の塗料供給路15a,15b、及び、これら2種の供給塗料Ta,Tbの夫々についてガン本体1で消費されなかった未消費分を返送する塗料返送路16a,16bを接続してあり、また、ガン本体1における先端部1aの側には、4本の内部塗料路17を通じて各塗料供給路15a,15b及び各塗料返送路16a,16bを接続した切換弁装置18を内装してある。   The swivel joint portion 14 has two paint supply paths 15a and 15b for supplying two kinds of paints Ta and Tb separately to the gun body 1, and a gun for each of these two kinds of supply paints Ta and Tb. The paint return paths 16a and 16b for returning the unconsumed portion that has not been consumed by the main body 1 are connected, and each paint is supplied to the tip 1a side of the gun body 1 through four internal paint paths 17. A switching valve device 18 connected to the paths 15a, 15b and the paint return paths 16a, 16b is provided.

また、計4つのノズル固定部5a,5bの塗料送出口7にはガン本体1の内部において切換弁装置18から個別の塗料送給路19を接続してある。   In addition, the paint supply outlets 7 of the four nozzle fixing portions 5a and 5b are connected to individual paint supply paths 19 from the switching valve device 18 inside the gun body 1.

切換弁装置18は内部塗料路17を通じ塗料供給路15a,15bから供給される2種の塗料Ta,Tbの夫々について各塗料送出口7に対する塗料送給路19への塗料送給を断続するものであり、この切換弁装置18により、計4つの塗料送出口7のうちいずれの塗料送出口7を塗料送出状態にするか(換言すれば、いずれの塗料ノズル2から塗料噴出させるか)を択一的に切り換える送出口切り換えを行い、また、2種の供給塗料Ta,Tbのうち塗料送出状態にある塗装送出口7に送給する塗料(換言すれば、択一選択した塗料ノズル2から噴出させる塗料)を択一的に切り換える塗料種切り換えを行なう。   The switching valve device 18 intermittently feeds the paint to the paint feed path 19 for each paint feed outlet 7 for each of the two types of paint Ta and Tb supplied from the paint feed paths 15a and 15b through the internal paint path 17. This switching valve device 18 selects which paint outlet 7 out of the total four paint outlets 7 is to be in the paint delivery state (in other words, which paint nozzle 2 ejects the paint). The paint outlet to be switched is switched, and the paint to be delivered to the paint delivery outlet 7 in the paint delivery state of the two types of supply paints Ta and Tb (in other words, sprayed from the paint nozzle 2 selected as an alternative) The paint type is switched selectively.

つまり、この切換弁装置18は上記の送出口切り換え機能を備えるとともに上記の塗料種切り換え機能を合わせ備える切換手段として機能する。   That is, the switching valve device 18 functions as switching means having the above-described delivery port switching function and the above-described paint type switching function.

図中20は塗装ガン1に対する制御器であり、この制御器20は、切換弁装置18に対する制御動作として、予め設定されたスケジュールに従って、向きの異なる各ノズル取付面部4a,4bの2つのノズル固定部5a,5bに取り付けた計4つの塗料ノズル2のうち順次に変わる各塗装部位の塗装に適した向き及び種類の塗料ノズル2から塗料噴出させるように塗装の進行に伴い塗装ロボットの動作と連係させて切換弁装置18を送出口切り換え動作させる。   In the figure, reference numeral 20 denotes a controller for the coating gun 1, and the controller 20 fixes two nozzles of the nozzle mounting surface portions 4a and 4b having different directions according to a preset schedule as a control operation for the switching valve device 18. Coordinates with the operation of the painting robot as the painting progresses so that the paint nozzle 2 of the direction and type suitable for painting of each painting part that changes sequentially among the total of four paint nozzles 2 attached to the parts 5a and 5b. Thus, the switching valve device 18 is operated to switch the delivery port.

また、この制御器20は、塗料噴出させる塗料ノズル2の上記の如き切り換えに伴い、切り換え先の塗料ノズル2から前記2種の塗料Ta,Tbのうち設定塗料種のものを噴出させるように切換弁装置18を塗料種切り換え動作させる。   Further, the controller 20 switches so that the set paint type of the two kinds of paints Ta and Tb is ejected from the paint nozzle 2 to which the paint is sprayed in accordance with the switching of the paint nozzle 2 to which the paint is ejected as described above. The valve device 18 is operated to switch the paint type.

即ち、この制御器20は、切換弁装置18の送出口切り換え機能により塗料送出状態とする塗料送出口7を択一的に切り換えるのに伴い、その送出口切り換えで塗料送出状態となる塗料送出口7に送給する塗料の塗料種を切換弁装置18の塗料種切り換え機能により設定塗料種に自動的に切り換える制御形態で切換弁装置18を制御する切換制御手段として機能する。   That is, the controller 20 selectively switches the paint delivery port 7 to be in the paint delivery state by the delivery port switching function of the switching valve device 18, and the paint delivery port that becomes the paint delivery state by switching the delivery port. 7 functions as a switching control means for controlling the switching valve device 18 in a control mode in which the coating material type of the coating material fed to 7 is automatically switched to the set coating material type by the coating material type switching function of the switching valve device 18.

なお、この制御器20では、塗料送出口7のうち切換弁装置18による塗料種切り換えが可能な塗料送出口7の夫々(本例では計4つの塗料送出口7の全て)について設定塗料種の変更を可能にしてある。   In this controller 20, the set paint type is set for each of the paint delivery ports 7 (all four paint delivery ports 7 in this example) of the paint delivery ports 7 that can be switched by the switching valve device 18. Change is possible.

以上、上記の如く被塗物に対する塗装の進行に伴い、向きの異なる各ノズル取付面部4a,4bの各2つのノズル固定部5a,5bに取り付けた塗料ノズル2のうち各時点の塗装部位の塗装に適した向き及び種類の塗料ノズル2から選択的に塗料噴出させるとともに、各時点の塗装部位に適した塗料種の塗料Ta,Tbを選択的に塗料ノズル2から噴出させることにより、高い塗装能率を得るとともに高い塗装品質を得られるように、また、塗装設備の簡素化及び設備コストの低減も合わせて図るようにしてある。   As described above, with the progress of the coating on the object to be coated, the coating portion at each time point is coated among the coating nozzles 2 mounted on the two nozzle fixing portions 5a and 5b of the nozzle mounting surface portions 4a and 4b having different directions. High paint efficiency by selectively ejecting paint from the paint nozzle 2 of the appropriate orientation and type, and by selectively spraying paint Ta and Tb of paint types suitable for the application site at each time point from the paint nozzle 2 In addition to achieving high paint quality, the paint equipment is simplified and the equipment costs are reduced.
