Description
【００１】[001]
本考案は、スリット状のノズル口を有するノズルより塗料を吐出させて、その 塗料を帯状物に連続的に塗装するノズルコ−タ−のノズル洗浄装置に関する。 The present invention relates to a nozzle cleaning device for a nozzle coater that discharges paint from a nozzle having a slit-shaped nozzle port and continuously applies the paint to a belt-like material.
【００２】[002]
従来一般に、鋼帯やアルミニウム帯などのような帯状物の連続塗装は、前処理 装置、ロ−ルコ−タ−および乾燥炉を順次配置した連続塗装ラインで行われてい るが、ロ−ルコ−タ−で塗装するには、塗料の希釈を必要とし、また、高速塗装 すると、アプリケ−タ−ロ−ルより塗料が飛散することから、近年、このような 欠点のないノズルコ−タ−が検討されている。 Conventionally, continuous coating of strips such as steel strips and aluminum strips has been carried out in a continuous coating line in which a pretreatment device, a roll coater and a drying oven are sequentially arranged. In order to paint with a painter, it is necessary to dilute the paint, and with high-speed painting, the paint is scattered from the applicator roll, so in recent years, a nozzle coater that does not have such defects has been investigated. Has been done.
【００３】 このノズルコ−タ−は、図４、図５に示すように、帯状物１を巻き付けるバッ キングロ−ル２の手前にスリット状のノズル口３を有するノズル４をそのノズル 口３がバッキングロ−ル２に巻き付けられた帯状物１と近接対向するように配置 して、帯状物１の移送速度、ノズル４からの塗料吐出量、帯状物とノズル先端と の距離を調整しながらノズル口３から吐出させた塗料を帯状物１に塗装するもの で、ノズル４への塗料供給は、塗料タンク５よりポンプ６を経てノズル４に達す る塗料供給管７を設けて行っていた。As shown in FIGS. 4 and 5, this nozzle coater has a nozzle 4 having a slit-shaped nozzle opening 3 in front of a backing roll 2 around which the belt-like material 1 is wound, and the nozzle opening 3 is a backing. It is arranged so as to closely face the strip 1 wound around the roll 2, and the nozzle port is adjusted while adjusting the transfer speed of the strip 1, the amount of paint discharged from the nozzle 4, and the distance between the strip and the tip of the nozzle. The paint discharged from No. 3 is applied to the strip 1, and the paint is supplied to the nozzle 4 by providing the paint supply pipe 7 that reaches the nozzle 4 from the paint tank 5 via the pump 6.
【００４】 このノズルコ−タ−で塗装する場合もロ−ルコ−タ−の場合と同様１基のノズ ルコ−タ−で種々の色や樹脂の塗料を塗装しなければならない。しかし、塗料変 えには、ノズル内部や塗料配管の洗浄を必要とする。この洗浄は、図６のように 塗料タンク５を溶剤タンク８に置き換えて、ポンプ６で溶剤をノズル４に送り、 ノズル口３より流れでた溶剤を容器９で受ける方法で行っていた。When coating with this nozzle coater as well as in the case of the roll coater, it is necessary to coat paints of various colors and resins with one nozzle coater. However, changing the paint requires cleaning the inside of the nozzle and the paint pipe. This cleaning was performed by replacing the paint tank 5 with the solvent tank 8 as shown in FIG. 6, sending the solvent to the nozzle 4 by the pump 6, and receiving the solvent flowing from the nozzle port 3 in the container 9.
【００５】[0095]
しかしながら、この方法では、溶剤を高速で送ると、ノズル４より高速で吐出 して、溶剤を回収できなくなるので、溶剤を高速で送ることができない。このた め、溶剤の供給は、緩やかにせざるを得ず、洗浄に時間を要していた。また、溶 剤が蒸発するため、作業環境を汚染するという問題もあった。 However, in this method, if the solvent is sent at a high speed, it cannot be discharged at a high speed from the nozzle 4 and the solvent cannot be recovered, so that the solvent cannot be sent at a high speed. For this reason, the supply of the solvent had to be slowed down, and it took a long time to wash. There is also a problem that the working environment is polluted because the solvent evaporates.
【００６】[0096]
本考案は、これらの問題を解消できるノズル洗浄装置を提供するもので、先端 に塗料吐出用のスリット状ノズル口を有するノズルに塗料供給管を接続したノズ ルコ−タ−のノズル先端部を収容でき、かつ、幅がノズル口部分より広いキャッ プを作製して、該キャップのノズル口と対向する部分に溶剤排出穴を形成し、キ ャップ外部の溶剤排出穴部分に溶剤排出管を固着した。また、この装置のキャッ プ内部の入側にノズル外側との係止機構を設けた。 The present invention provides a nozzle cleaning device capable of solving these problems, and accommodates the nozzle tip portion of a nozzle coater in which a paint supply pipe is connected to a nozzle having a slit-shaped nozzle opening for coating the tip. A cap that can be made and has a width wider than the nozzle opening is made, a solvent discharge hole is formed in the portion of the cap facing the nozzle opening, and a solvent discharge pipe is fixed to the solvent discharge hole outside the cap. . In addition, a locking mechanism with the outside of the nozzle was provided on the entrance side inside the cap of this device.
【００７】[0097]
キャップをノズル先端部に取り付ければ、ノズル口より吐出する溶剤は、溶剤 排出穴を経て溶剤排出管より出てゆく。従って、溶剤排出管の先端を溶剤タンク に配管しておけば、溶剤を高圧高速で循環でき、溶剤の蒸発もない。また、キャ ップ内部の入側にノズル外側と係止機構を設けておけば、洗浄装置のノズル先端 部への取り付けが容易になる。 If the cap is attached to the tip of the nozzle, the solvent discharged from the nozzle exits from the solvent discharge pipe through the solvent discharge hole. Therefore, if the end of the solvent discharge pipe is connected to the solvent tank, the solvent can be circulated at high pressure and high speed, and the solvent will not evaporate. Also, if a locking mechanism is provided on the inside of the cap on the outside of the nozzle, it can be easily attached to the tip of the nozzle of the cleaning device.

図１〜図３は、本考案に係るノズル洗浄装置をノズル４に装着した場合の実施 例を示すもので、ノズル４の上下には凸条１０が設けられている。そして、この ノズル４の先端部には、凸条１０より深い部分までキャップ１１が装着されてい る。 1 to 3 show an embodiment in which the nozzle cleaning device according to the present invention is attached to the nozzle 4, and convex ridges 10 are provided above and below the nozzle 4. A cap 11 is attached to the tip of the nozzle 4 to a portion deeper than the ridge 10.
【００９】 キャップ１１は、内側断面がノズル４の先端部断面と同一形状の溝になってい て、その溝の最深部にはゴムパッキン１２が全幅にわたり固着されている。この ゴムパッキン１２は、ノズル４のノズル口３と密着し、幅方向中心部には、ノズ ル口３と連通する穴１３があけられている。また、ゴムパッキン１２の穴１３が あけられた部分のキャップ１１には、外部に達する穴１４があけられ、その穴１ ４の部分に溶剤排出管１５が固着されている。The cap 11 has a groove whose inner cross section has the same shape as the cross section of the tip of the nozzle 4, and a rubber packing 12 is fixed over the entire width in the deepest part of the groove. The rubber packing 12 is in close contact with the nozzle opening 3 of the nozzle 4, and a hole 13 communicating with the nozzle opening 3 is formed at the center in the width direction. Further, a hole 14 reaching the outside is formed in the cap 11 in the portion where the hole 13 of the rubber packing 12 is formed, and a solvent discharge pipe 15 is fixed to the portion of the hole 14.
【０１０】 キャップ１１の入側には、ノズル４の凸条１０と嵌合する凹条１６が形成され ていて、キャップ１１をノズル４の幅方向に摺動させるだけで脱着できるように なっている。On the entrance side of the cap 11, there is formed a concave line 16 that fits with the convex line 10 of the nozzle 4, so that the cap 11 can be attached and detached simply by sliding the cap 11 in the width direction of the nozzle 4. There is.
【０１１】 この洗浄装着は、図１に示すように、塗料タンク５の近くに一次洗浄用溶剤タ ンク１７、二次洗浄用溶剤タンク１８を配置して、図示のようにこれらに配管を 施す。ここで、塗料タンク５から塗料をポンプ６で吸い上げて、ノズル４に供給 する塗装が完了したなら、塗料供給管７のバルブ１９は閉め、かつ、溶剤排出管 １５のバルブはバルブ２０および２１のみを開けて、ポンプ６を作動させれば、 一次洗浄用溶剤タンク１７よりの溶剤がノズル４内を通りながら循環し、一次洗 浄できる。In this cleaning installation, as shown in FIG. 1, a primary cleaning solvent tank 17 and a secondary cleaning solvent tank 18 are arranged near the paint tank 5, and pipes are provided to these as shown. . Here, when the paint is sucked up from the paint tank 5 by the pump 6 and the coating to be supplied to the nozzle 4 is completed, the valve 19 of the paint supply pipe 7 is closed, and the valve of the solvent discharge pipe 15 is only the valves 20 and 21. By opening and opening the pump 6, the solvent from the primary cleaning solvent tank 17 circulates while passing through the nozzle 4, and the primary cleaning can be performed.
【０１２】 この一次洗浄が完了したなら、溶剤排出管１５のバルブのうちのバルブ２２お よび２３のみを開けて、ポンプ６を作動させれば、二次洗浄用溶剤タンク１８よ り新しい溶剤を循環させることができる。二次洗浄が完了したなら、塗料タンク ５を移動させて、そこに一次洗浄用溶剤タンク１７を移動させ、さらに、一次洗 浄用溶剤タンク１７あったところに二次洗浄用タンク１８を移動させて、そこに 新たに塗装する塗料の塗料タンクを配置すればよい。When this primary cleaning is completed, only the valves 22 and 23 of the solvent discharge pipe 15 are opened, and the pump 6 is operated. Can be circulated. When the secondary cleaning is completed, the paint tank 5 is moved, the primary cleaning solvent tank 17 is moved there, and the secondary cleaning tank 18 is moved to the place where the primary cleaning solvent tank 17 was. Then, a paint tank for the paint to be newly painted may be placed there.
【０１３】[0113]
以上のように、本考案のノズル洗浄装着は、洗浄用溶剤が循環する構造になっ ているので、洗浄用溶剤を高圧高速で循環できる。このため、洗浄時間が大幅に 短縮され、溶剤蒸発による作業環境汚染も防止される。 As described above, the nozzle cleaning device of the present invention has a structure in which the cleaning solvent is circulated, so that the cleaning solvent can be circulated at high pressure and high speed. As a result, the cleaning time is greatly reduced and the work environment is prevented from being contaminated by solvent evaporation.
