Abstract

A glassy coating (27) having high surface hardness and chemically stable against contact by a solvent such as thinner is applied to an inner peripheral surface (26A) of a cylinder section (26) forming a tank (23) of a body (22). Further, a seal member (30) of a piston (29) moves while sliding on an inner peripheral surface (27A) of the glassy coating (27). Since the glassy coating (27) is excellent in dust prevention ability and ability to be cleaned, paint and thinner adhered to the inner peripheral surface (27A) can be efficiently removed when the seal member (30) of the piston (29) slides. The replacement cycle of push-out thinner can be extended, and a change in quality of paint caused by mixing-in of the push-out thinner can be prevented.

本発明は、 例えば塗装機に対し交換して取付けられ 内部に充填された塗料を塗装機に向けて供給する塗装用 カー ト ッジに関する。  The present invention relates to a coating cartridge that supplies, for example, a coating material that is exchanged and installed inside a coating machine to the coating machine.

ステムは 、 塗装用口ポッ ト等の作業機と 、 該作業機に取 付けられた塗装機とから構成されている の塗装シス テムは 前記塗装作業機をプログラムによつて動作し 塗装機から塗料を噴霧する こ とによ り 動的に塗装を行 なう ことができる。 The stem is composed of a work machine such as a painting mouth pot and a paint machine attached to the work machine. The paint system operates the paint work machine according to a program and paints from the paint machine. It is possible to perform painting dynamically by spraying.
また 昨今では、 色替時に廃棄される塗料の削減 洗 浄流体の削減、 塗色の増大等に対応するため 塗装シス テムとして、 塗装用カー ト リ ッジを用いた力 卜 U ッン 式塗装システムがある。 この力一 ト リ ッジ式塗装システ ムは、 異なる塗色の塗料が充填された各色毎の塗装用力 ー 卜 リ ッジを、 自動車のボディ を塗装する度に塗装機に 対し交換して取付ける構成となっている (例えば、 特開 In recent years, the use of paint cartridges as a painting system to reduce the amount of paint discarded during color change, the reduction of cleaning fluids, and the increase in paint color. There is a system. This trige-type coating system replaces and installs the painting power for each color filled with paint of different paint colors to the painting machine every time the automobile body is painted. (For example, JP

で 、 上述した従来技術による力 卜 U ジ式塗装 システムに用いられる塗装用力一 ト リ ッジは 次のよ な構成となっている。 即ち、 塗装用力 卜 U ッジは 塗 装機に着脱可能に取付けられ、 筒状をした中空なタンク と該タンクから軸方向の前側に延びたフィ ― ドチュ ブ とからなるホディ と、 該ホディ の夕 ンク内を軸方向に移 動可能に配置され 、 その外周側に BXけられたシール部材 によ り該タンク内を塗料を収容する塗料収容室と押出し シンナが流入, 流出する押出しシンナ収容室とに画成す る ピス 卜ンと、 刖記塗料収容室とフイ ー ドチューブの先 側との間を連 Mし、 塗料弁によ Ό塗料の吐出が行なわ れる塗料通路と HU記塗 ¾機側の押出しシンナ通路と前 記押出しシンナ収容室とを連通し、 前記押出しシンナ収 容室に押出しシンナの流入, 流出が行なわれる押出しシ ンナ通路とによって大略構成されている。 Thus, the power-triggering trig used in the above-described conventional force-coating system has the following structure. That is, the painting power 卜 U wedge is detachably attached to the coating machine, and a hollow cylindrical tank and a feed tube extending from the tank to the front side in the axial direction. And a paint storage chamber for storing paint in the tank by a seal member BX disposed on the outer periphery of the body, and an extrusion thinner. The piston that is defined in the extrusion thinner storage chamber where the inflow and outflow of water flow is connected between the paint storage chamber and the front side of the feed tube, and the paint is discharged by the paint valve. The paint passage is generally constituted by an extrusion thinner passage on the HU coating machine side and an extrusion thinner passage through which the extrusion thinner flows into and out of the extrusion thinner storage chamber. ing.
そして、 ビス ト ンの外周側にはシール部材が設けられ、 のシ ル部材は、 タンクの内周面に常に摺接する こと により塗料収容室と押出しシンナ収容室との間を 液密 にシ ルし、 塗料収容室の塗料と押出しシンナ収容室の 押出しシンナとが混合するのを防止している。  A seal member is provided on the outer peripheral side of the piston, and the seal member is always in sliding contact with the inner peripheral surface of the tank so that a liquid-tight seal is formed between the paint storage chamber and the extrusion thinner storage chamber. In addition, the paint in the paint chamber is prevented from mixing with the extruded thinner in the extruded thinner chamber.
のよう に構成された塗装用カー ト リ ッジは、 塗色に 応じて選択されたものが塗装機に対して取付けられる o そして 、 塗料弁を開弁させ、 タンク内の押出しシンナ収 容室に押出しシンナを適宜供給する ことによ り、 夕ンク 内の塗料収容室に充填された塗料を塗料通路を介してフ ィ チューブの先端から塗装機に向け吐出する これ によ り 、 塗装機は、 回転霧化頭等の霧化手段で塗料を霧 化し、 被塗物に向け噴霧する。  The coating cartridge configured as follows is installed on the coating machine according to the coating color o and the paint valve is opened and the extrusion thinner storage chamber in the tank is opened. By appropriately supplying extrusion thinner to the pipe, the paint filled in the paint chamber in the evening is discharged from the tip of the tube to the coater through the paint passage. The paint is atomized by an atomizing means such as a rotary atomizing head and sprayed on the object.
また、 塗装用カー ト リ ッジは、 他色の塗料が充填され た他の塗装用カー ト リ ッジに交換するだけで、 塗料、 洗 浄流体を廃棄する ことなく 、 塗料の色替を行なう こ とが できる。 そして、 空になったカー ト リ ッジは、 塗装機か ら取外されて塗料充填装置に取付けられ、 該塗料充填装 置によ り塗料収容室に塗料が充填される。 ところで、 上述した従来技術による塗装用力ー 卜 リ ッ ジでは、 ビス 卜 ンの外周側にシ ―ル部材を設け 、 該シ一 ル部材によつて塗料収容室の塗料と押出しシンナ収容室 の押出しシンナとが混ざるのを防止している。 しかし 、 塗装作業中や塗料充填作業中には 、 ビス 卜 ンのシール部 材とタンクの内周面とは摺動を繰返すから、 塗料収容室 の塗料が押出しシンナ収容室に 、 また押出しシンナ収容 室の押出しシンナが塗料収容 に僅かずつ流入してしま う ことがある In addition, the paint cartridge can be replaced with another paint cartridge filled with another color paint, and the paint color can be changed without discarding the paint or cleaning fluid. Can be done. The emptied cartridge is removed from the coating machine and attached to the paint filling device, and the paint containing chamber is filled with the paint by the paint filling device. By the way, in the above-described conventional coating force-ridge, a seal member is provided on the outer peripheral side of the screw line, and the seal member pushes the paint in the paint chamber and the extrusion thinner chamber. It prevents mixing with thinner. However, during the painting operation and the paint filling operation, the seal member of the screw and the inner peripheral surface of the tank are repeatedly slid, so that the paint in the paint storage chamber is stored in the extrusion thinner storage chamber and the extrusion thinner storage. Extrusion thinner in the chamber may gradually enter the paint container
このようなシンナの流入現象は 、 タンクの内周面が僅 かに凹凸状となつているため 、 シ一ル部材が夕ンクの内 周面を摺動したとさに、 この凹凸部分で塗料と押出しシ ンナが残留と離脱を繰返している ことによるものである しかも、 シール部材は、 内周面の凹凸部分を摺動する と さに僅かずつ損傷を繰返しているから、 そのシ —ル性が 加速度的に低下して、 塗料と押出しシンナとが混入しあ とになる。  This phenomenon of thinner inflow is because the inner peripheral surface of the tank is slightly uneven, so that the seal member slides on the inner peripheral surface of the tank, and this uneven portion paints This is because the sealer is repeatedly damaged and removed repeatedly as it slides on the concave and convex portions of the inner peripheral surface. Decreases at an accelerated rate, and paint and extruded thinner are mixed together.
そして、 押出しシンナ収容室に塗料が混入すると 、 シ ンナの純度が低下し、 電気絶縁性が低下する。 塗料に高 圧を印加する静電塗装の場合、 押出しシンナの電気絶 縁性が低下する と 、 押出しシンナを通じて高電圧がァ一 スに漏洩してしまい、 静電塗装が維持できなく なる のため、 押出しシンナ収容室と押出しシンナを供給する シンナ供給装置との間の多量の押出しシンナを頻繁に交 換しなくてはならず、 生産性の低下、 ランニングコス 卜 の上昇を招く という問題がある。  When paint is mixed into the extruded thinner storage chamber, the purity of the thinner is lowered and the electrical insulation is lowered. In the case of electrostatic coating that applies high pressure to the paint, if the electrical insulation of the extrusion thinner decreases, a high voltage leaks through the extrusion thinner and the electrostatic coating cannot be maintained. There is a problem that a large amount of extrusion thinner must be frequently replaced between the extrusion thinner storage chamber and the thinner supply device, which causes a decrease in productivity and an increase in running cost 卜. .
一方、 塗料収容室に押出しシンナが混入すると、 押出 しシンナによつて塗料の性質が変化してしまうから 、 塗 装仕上り面や塗膜物性などに様々な不具合が生じ、 塗装 品質が低下する という問題がある o On the other hand, if extruded thinner enters the paint chamber, the properties of the paint change due to the extruded thinner, which causes various problems in the finished surface of the coating and physical properties of the coating. There is a problem that the quality deteriorates o
そこで、 塗装用力 — ト リ ッジでは 、 ビス 卜 ンのシール 部材が摺動する夕ンクの内周面の表面仕上げを細かく し、 凹凸をなくすことによ り、 表面に残留する塗料 、 押出し シンナを削減する といった方策がと られている o よ / 、 シ ル部材を改良して、 表面に残留する塗料 、 押出しシ ンナを搔き取るような機能 (スク レ一パ機能 ) を持たせ る うにしている  Therefore, in the coating force—tridge, the surface finish of the inner circumferential surface of the piston on which the seal member of the screw slides is made fine, and the unevenness is eliminated, so that the paint remaining on the surface, the extrusion thinner O / / Improve the seal member to have a function (scraper function) to scrape paint and extrusion thinner remaining on the surface. I have to
しかし、 タンクの内周面に塗料、 押出しシンナが残留 する原因は、 表面の物 的な凹凸だけでなく 、 化学親和 性等の影響も大きい のため、 タンクの内周面の表面 粗さを細かく したり ン一ル部材に 搔き取り機能を持た せたり しても、 夕ンクの内周面から塗料、 押出しシンナ を効果的に除去する とができないという問題がある。 発明の開本  However, the reason why paint and extrusion thinner remain on the inner peripheral surface of the tank is not only due to physical irregularities on the surface, but also due to the influence of chemical affinity, etc., so the surface roughness of the inner peripheral surface of the tank is fine. However, there is a problem in that the paint and the extruded thinner cannot be effectively removed from the inner peripheral surface of the tank even if the seal member has a scraping function. Invention invention
本発明は上述した従来技術の問 に鑑みなされたもの で、 本発明の目的は、 ビス 卜ンの 過後にタンクの内周 面に残留する塗料、 押出し液体を なくする こ とによ り、 塗料と押出し液体との混合を抑制 て生産性、 PP 等を向上できるよう にした塗装用 — 卜 リ ッジを提供す る ことにある。  The present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to eliminate paint and extrusion liquid remaining on the inner peripheral surface of a tank after passing through a resin by coating. It is intended to provide a coating-type lid that can improve the productivity, PP, etc. by suppressing the mixing of the resin and the extrusion liquid.
( 1 ) .本発明による塗装用力一卜 リ ッ ジは、 筒状を した中空なタンク と該タンクから軸方向の前側に延びた フィ ー ドチューブとからなるポディ と、 該ポディ のタン ク内を軸方向に移動可能に配置されその外周側に設けら れたシール部材によ り該タンク内を塗料収容室と押出し 液体収容室とに画成する ビス ト ンと、 前記塗料収容室と フィ 一 ドチューブの先端側との間を連通し塗料弁によ り 塗料の吐出が行なわれる塗料通路と、 前記押出し液体収 容室に押出し液体の流入 , 流出が行なわれる押出し液体 通路とを備 てなる。 (1) A painting power ridge according to the present invention comprises a pody comprising a hollow cylindrical tank and a feed tube extending axially forward from the tank, and the inside of the pod. A piston which is arranged so as to be movable in the axial direction and is provided on the outer peripheral side of the tank to define a paint containing chamber and an extruded liquid containing chamber in the tank, and the paint containing chamber and Connected to the end of the tube with a paint valve A paint passage in which paint is discharged and an extruding liquid passage in which extruding liquid flows in and out of the extruding liquid storage chamber are provided.
そして、 上述した課題を解決するために、 本発明が採 用する構成の特徴は、 刖記ボディ のタンクは、 少なく と も目 記ビス ト ンのシ一ル部材が摺動する内周面をガラス 材またはガラス材を主成分とする材料によって形成した ことにある。  In order to solve the above-described problems, the configuration of the present invention is characterized by the fact that the tank of the above-mentioned body has at least an inner peripheral surface on which the seal member of the above-mentioned piston slides. It is made of glass or a material mainly composed of glass.
こ こで、 ボディ のタンクの内周面を形成するガラス材 またはガラス材を主成分とする材料は、 表面硬度が高く 、 またシンナ等の液体の接触に対しても化学的に安定して いるから、 防汚性、 洗浄性に優れている。 れによ り、 タンクの内周面に付着した塗料、 押出し液体は 、 ビス 卜 ンのシール部材が摺動するときに該シール部材によって 効率よく除去する ことができる。  Here, the glass material that forms the inner peripheral surface of the tank of the body or a material mainly composed of glass material has a high surface hardness and is chemically stable against contact with liquids such as thinner. Therefore, it has excellent antifouling and cleaning properties. As a result, the paint and extruded liquid adhering to the inner peripheral surface of the tank can be efficiently removed by the seal member when the screw seal member slides.
この結果、 押出し液体収容室に流入する塗料の量を大 幅に削減する こ とができるから、 例えば塗料に高電圧を 印加する静電塗装を行なう場合でも、 押出し液体と して 用いる押出しシンナの電気絶縁性を長期に亘 て維持す る こ とができる。 これによ り 、 押出しシンナの交換サイ クルを長くする こ とができ、 生産性の向上 ランニング ス トの低減等を図る ことができる。 一方 塗料収容室 に流入する押出し液体の量も大幅に削減する とができ るから、 塗料が押出し液体によって変質するのを防止で さ、 塗装品質を向上する ことができる。  As a result, the amount of the paint flowing into the extrusion liquid storage chamber can be greatly reduced. For example, even when electrostatic coating is performed by applying a high voltage to the paint, the extrusion thinner used as the extrusion liquid is used. Electrical insulation can be maintained for a long time. As a result, the replacement cycle of the extrusion thinner can be lengthened, and productivity can be improved and the running cost can be reduced. On the other hand, since the amount of the extrusion liquid flowing into the paint chamber can be greatly reduced, it is possible to prevent the paint from being altered by the extrusion liquid and to improve the coating quality.
さ らに、 ガラス材またはガラス材を主成分とする材料 によゥて形成されたタンクの内周面は、 ピス ト ンのシ ル部材を円滑に摺動させる とができるから、 該シール 部材に皺や撚れが生じるのを防止する ことがでさ シ― ル部材の耐久性を向上する ことができる。 Further, since the inner peripheral surface of the tank formed of glass material or a material mainly composed of glass material can smoothly slide the piston seal member, the seal member To prevent wrinkles and twists from occurring The durability of the steel member can be improved.

May be.
これによ り、 ボディ を構成する夕 ンクの内周面に対し て 、 ガラス材またはガラス材を主成分とする材料をコ一 ティ ングする こ とによ りガラス質被膜を容易に形成する し とができる。 また、 ガラス質被膜は薄く形成する こ と ができるから、 既存のタンクにも形成する ことができる As a result, a glassy film can be easily formed by coating a glass material or a material mainly composed of a glass material on the inner peripheral surface of the bank constituting the body. You can. In addition, since the glassy coating can be formed thinly, it can also be formed in existing tanks.
( 3 ) .本発明では、 前記ポディ のタ ンク には、 その 内周側にガラス材またはガラス材を主成分とする材料を 用いて筒状に形成されたガラス製筒体を揷嵌する構成と してもよい。 (3) In the present invention, a glass cylinder formed into a cylindrical shape using a glass material or a material mainly composed of a glass material is fitted on the inner periphery of the tank of the poddy. It may be.
これによ り、 ボディ のタンク内にはガラス材またはガ ラス材を主成分とする材料から筒状に形成されたガラス 製筒体を揷嵌するだけで、 ピス トンのシール部材をガラ ス製筒体の内周面で摺動させる ことができるから、 焼成 等の特殊な作業を省略する こ とができ、 組立作業性を向 上することができる。  As a result, a glass cylinder formed into a cylindrical shape from a glass or glass material as a main component is fitted into the body tank, and the piston seal member is made of glass. Since it can be slid on the inner surface of the cylinder, special work such as firing can be omitted, and assembly workability can be improved.

第 1 の実施の形態による回転霧化頭型塗装システム 1 は上述の如き構成を有するもので、 次に、 塗装用カー ト リ ッジ 2 1 を用いた塗装動作について説明する。  The rotary atomizing head type coating system 1 according to the first embodiment has the above-described configuration. Next, the coating operation using the coating cartridge 21 will be described.
まず、 塗料収容室 3 1 に塗料が充填された塗装用カー ト リ ッ ジ 2 1 を、 図 1 に示すよう に、 ハウジング 2 の力 ー ト リ ッジ取付部 4 に取付ける。 次に、 この状態でシン ナ弁 1 4、 塗料弁 3 4を開弁する。 そして、 押出しシン ナ通路 1 3 , 3 6 を介して押出しシンナ収容室 3 2 に押 出しシンナを供給すると、 ピス ト ン 2 9 は塗料収容室 3 1 を縮小する方向に変位する。 これによ り、 塗料収容室 3 1 内の塗料は、 塗料通路 3 3 を介してフィ ー ドチュー ブ 2 8 の先端から回転霧化頭 8 に向け吐出される。 First, as shown in FIG. 1, the coating cartridge 21 with the coating material chamber 3 1 filled with the coating material is attached to the force cartridge mounting portion 4 of the housing 2. Next, in this state, the thinner valve 14 and the paint valve 3 4 are opened. When the extrusion thinner is supplied to the extrusion thinner housing chamber 3 2 through the extrusion thinner passages 13 and 3 6, the piston 29 is displaced in the direction in which the paint housing chamber 31 is reduced. As a result, the paint in the paint storage chamber 3 1 is fed through the paint passage 3 3 to the feed tube. It is discharged toward the rotary atomizing head 8 from the tip of the tube 28.
のときには、 高電圧発生器 1 0 によって塗料を高電 圧に帯電させる。 これによ り 、 フィ ー ドチューブ 2 8 か ら吐出された塗料は、 回転霧化頭 8 によって霧化されつ In this case, the high voltage generator 10 is used to charge the paint to a high voltage. As a result, the paint discharged from the feed tube 28 is atomized by the rotary atomizing head 8.
、 被塗物 (図示せず) との間に形成される電気力線に 沿ゥて飛行し、 該被塗物に塗着する。 Fly along the lines of electric force formed between the object to be coated (not shown) and apply to the object to be coated.
次に、 塗装作業を行なう こ とによ り空になった塗装用 力一 ト リ ッジ 2 1 に塗料を充填する場合の充填動作につ いて説明する。  Next, the filling operation in the case where the paint is filled in the coating force trig 21 which has been emptied by the painting work will be described.
まず、 塗装動作が終了した塗装用カー ト リ ッジ 2 1 は 八ゥジング 2 のカー ト リ ッジ取付部 4から取外し、 該カ 一 卜 リ ッジ 2 1 のフィー ドチューブ 2 8 を塗料充填装置 の充填台 (図示せず) に取付ける。 この状態で塗料弁 3 First, the painting cartridge 2 1 after the painting operation has been removed from the cartridge mounting portion 4 of the eight housing 2 and the feed tube 2 8 of the cartridge 21 is connected to the paint filling device. Attach to the filling table (not shown). Paint valve 3 in this state
4 を開弁する こ とによ り、 塗料供給源からの塗料を塗料 通路 3 3 の先端開口 3 3 Aに流入させ、 該塗料通路 3 3 を介して塗料収容室 3 1 内に塗料を充填する。 By opening 4, the paint from the paint supply source flows into the tip opening 3 3 A of the paint passage 3 3 and fills the paint storage chamber 3 1 through the paint passage 3 3. To do.
し こで、 塗装用カー ト リ ッジ 2 1 から塗料を吐出する 場 a には、 塗料収容室 3 1 の容積を縮小するようにビス h ン 2 9 が前側に変位する。 一方、 塗装用カー ト リ ッジ Thus, in the place a where the paint is discharged from the paint cartridge 21, the screw 29 is displaced forward so as to reduce the volume of the paint storage chamber 31. Meanwhile, the paint cartridge
2 1 に塗料を充填する場合には、 塗料収容室 3 1 の容積 を拡大するよう にピス トン 2 9 が後側に変位する。 When 2 1 is filled with paint, the piston 2 9 is displaced rearward so as to expand the volume of the paint containing chamber 3 1.
そして、 ピス ト ン 2 9 が前側に変位する と、 ピス ト ン When piston 29 is displaced to the front, piston
2 9 のシール部材 3 0 は、 ガラス質被膜 2 7 の内周面 22 9 seal member 30 is the inner peripheral surface 2 of glassy coating 2 7
7 Aに密着して摺動するから、 塗料収容室 3 1 内でガラ ス質被膜 2 7 の内周面 2 7 Aに付着した塗料は、 シール 部材 3 0 によって効果的に除去する ことができる。 7 Since it slides in close contact with A, the paint adhering to the inner peripheral surface 2 7 A of the glassy coating 2 7 in the paint containing chamber 3 1 can be effectively removed by the seal member 30. .
(―れによ り、 ガラス質被膜 2 7 の内周面 2 7 Aに残留 する塗料を大幅に削減することができるから、 押出しシ ンナ収容室 3 2 に流入する塗料の量を極僅かに抑える こ とがでさる。 また、 ピス ト ン 2 9 が後側に変位したとさ にも 1 J様に塗料収容室 3 1 に流入する押出しシンナの 量を極僅かに抑える ことができる。 (This can greatly reduce the amount of paint remaining on the inner peripheral surface 27 A of the vitreous coating 27, so that the amount of paint flowing into the extrusion chamber 3 2 is very small. Hold down Togashi. Further, when the piston 29 is displaced to the rear side, the amount of the extrusion thinner that flows into the paint containing chamber 3 1 like 1 J can be minimized.
か < して、 第 1 の実施の形態によれば、 ボディ 2 2 の 夕ンク 2 3 を形成するシリ ンダ部 2 6 の内周面 2 6 Aに は、 表面硬度が高く 、 シンナ等の溶剤の接触に対しても 化学的に安定したガラス質被膜 2 7 を設ける構成と して いる 従つて、 ビス ト ン 2 9 のシール部材 3 0が摺動す るガラス質被膜 2 7 の内周面 2 7 Aは、 防汚性、 洗浄性 に優れているから、 この内周面 2 7 Aに付着した塗料 押出しシンナは、 ピス ト ン 2 9 のシール部材 3 0が摺動 するとさに効率よく除去する ことができる。  However, according to the first embodiment, the inner peripheral surface 26 A of the cylinder portion 2 6 that forms the tank 2 3 of the body 2 2 has a high surface hardness and is a solvent such as thinner. Therefore, the inner surface of the glassy coating 2 7 on which the sealing member 30 of the piston 29 slides is provided. 27 A has excellent antifouling properties and cleanability, so the paint extruding thinner adhering to this inner peripheral surface 27 A is more efficient when the piston 29 seal member 30 slides. Can be removed.
の 口 :果、 押出しシンナ収容室 3 2 に流入する塗料の 量を大幅に削減する ことができるから、 高電圧発生器 1Mouth : Fruit, Extrusion Thinner Chamber 3 2 Since the amount of paint flowing into the chamber can be greatly reduced, the high voltage generator 1
0 に つて塗料に高電圧を印加する静電塗装を行なう場 合でち 押出しシンナの電気絶縁性を長期に亘つて維持 する とができる。 これによ り、 押出しシンナの交換サ ィ クルを長くする ことができ、 生産性の向上、 ラン二ン グコス 卜の低減等を図ることができる。 In the case of applying electrostatic coating by applying a high voltage to the paint, it is possible to maintain the electrical insulation of the extruded thinner for a long time. As a result, the replacement cycle of the extruded thinner can be lengthened, and productivity can be improved and the running cost can be reduced.
一方 塗料収容室 3 1 に流入する押出しシンナの量 大幅に削減する こ とができるから、 塗料が押出しシンナ の混入によって変質するのを防止でき、 塗装品質を向上 する とができる。  On the other hand, since the amount of extrusion thinner flowing into the paint chamber 31 can be greatly reduced, it is possible to prevent the paint from being deteriorated due to mixing of the extrusion thinner, and to improve the coating quality.
しか 、 ガラス質被膜 2 7 の内周面 2 7 Aは、 ビス 卜 ン 2 9 のシール部材 3 0 を円滑に摺動させる こ とがでさ るから 該シール部材 3 0 に皺や撚れが生じるのを防止 する とができ、 シール部材 3 0 の耐久性を向上する とがでさる  However, since the inner peripheral surface 27 A of the glassy coating 27 can smoothly slide the seal member 30 of the screw 29, the seal member 30 is not wrinkled or twisted. Can be prevented, and the durability of the seal member 30 can be improved.
また ガラス質被膜 2 7 は、 ガラス材を主成分とする 材料 (ポリ シラザン) をシリ ンダ部 2 6 の内周面 2 6 A にコーティ ングする とによ り容易に形成する とがで さる。 また 、 ガラス質被膜 2 7 は薄 <形成する とがで きるから、 既存の塗 &用力一 卜 リ V ンにも少ない加ェで 形成する ことができる The glassy coating 2 7 is mainly composed of glass. It can be easily formed by coating the material (polysilazane) on the inner peripheral surface 26 A of the cylinder portion 26. In addition, since the glassy coating 27 can be formed thinly, it can be formed with a small amount of heat even in the existing coating & application power.
