Description

201134558 VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to paint crucibles and electrostatic coating machines. [Prior Art] As an electrostatic coating machine suitable for a conductive coating such as an aqueous coating or a metallic coating, a coating-type electrostatic coating machine is known. The paint-type electrostatic coating machine has a paint that is detachably assembled into the body of the coating machine. The paint-type electrostatic coating machine uses a conductive paint contained in the paint cartridge to coat the automobile body or the like. Installed. The paint-type electrostatic coating machine has the advantage of blocking high voltage leakage to the outside through the conductive coating. A conventional electrostatic coating machine that receives a supply of paint from an external paint source is roughly classified into a rotary atomizing coating machine having a rotary atomizing head (ie, a "bell cup") and a spray coating 胄 'When ^ Both types of coating machines can apply paint enamel. The paint enamel, which is also called a paint box or a paint box unit, can be roughly classified into [first, a piston type that uses a piston to extrude a paint (Patent Documents 1 to 3); and second, a pressure is applied to a paint bag by being squeezed. A paint bag type in which a paint bag is extruded from a paint bag (Patent Documents 4 to 6). Specifically, the piston type coating material of Patent Document 丨3 has a paint accommodating chamber divided by a piston, and a liquid working chamber that sandwiches the piston and is opposite to the paint accommodating chamber, and the piston coating (four) is used An actuating liquid (typically a non-conductive liquid such as a diluent) is supplied to the working fluid chamber to press the piston, 201134558 to extrude the paint in the paint accommodating chamber from the coating E, and supply the paint to the clock through the feeding tube Cup. Further, the coatings of Patent Documents 丨 to 3 have a feed tube which can be inserted into the body of the coating machine, and therefore may also be referred to as a coating material for attaching a feeding tube. Patent Document 4, as described above, discloses a paint cartridge having a paint bag for forming a paint storage chamber, and a paint cartridge of Patent Document 4 having a feed tube insertable into the body of the coating machine. Therefore, the coating material S disclosed in Patent Document 4 can also be referred to as a coating material attached to a feeding tube. As a method of pressing a paint bag, Patent Document 4 discloses two types. One of the methods is to supply an operating fluid to the periphery of the paint bag, and the working fluid is directly applied to the paint bag to press the paint bag. Another method is to prepare a fluid bag adjacent to the paint bag and forming an activator chamber, and the activator is expanded by supplying the activator to the activator bag to apply pressure to the paint bag by using the expanded liquid bag. Squeeze the paint bag. Patent Document 5 proposes a solution in which the contact faces of the paint bag and the liquid-moving bag are joined to each other in a coating bag having a paint bag and a working fluid bag to prevent relative displacement of the paint bag and the fluid bag. Further, Patent Document 5 proposes a solution in which a liquid is filled in the gap between the paint bag and the working fluid bag. There is a paint enamel which is made of a transparent hard plastic or a nylon resin to make an outer shell of a paint enamel having a paint bag so as to be able to observe internal flaws and slipperiness. Further, Patent Document 6 discloses that the paint bag is also made of a transparent resin. And the paintable enamel can be stored and coated relative to the coating machine body 201134558

The amount of material is limited. Therefore, for example, apricot a, a gentleman, a port, such as the first car body painting, at the end of the painting, the paint must be replaced for the next car body painting. Patent Document 7 discloses a technique for replacing paint E with a coating robot having an electrostatic coating machine. Specifically, when the painting of a car body is finished, the paint is replaced in the replacement platform, and the used paint is removed from the body of the coating machine, and the new paint cartridge is assembled to the body of the coating machine. in. That is to replace the paint g. In addition, when the painting robot is: When painting the automobile body, in the paint 匣 replacement platform, the operation of filling the paint into the used paint " and filling the paint-filled paint 匣's reserve again use. Regarding the application of the paint to the emptying, it is filled with the paint for reuse, and for the piston paint, t' is actually performing color change. That is, the piston paint crucible can be filled with the same color of the paint, or as described in detail in the patent documents 丨, 2, first wash the interior of the paint (paint containment chamber), and then fill the paint of other colors' Change color. For the coating of the coating disclosed in the patent reading, first, the piston is pressed down until the deepest portion of the coating is received, and the paint contained in the coating is discharged. The reason why the piston is not pressed down to the deepest part, but the piston is stopped at the deepest point, because if the piston is pressed down to the deepest part of the paint storage, that is, the bottom wall of the paint storage chamber, then Even if the cleaning liquid is allowed to enter the paint storage chamber, the cleaning liquid cannot flow inside the paint storage chamber. (Paragraph of the specification of Patent Document i [〇153]) In this state, that is, the piston is positioned at a position slightly at the foremost position in the deepest portion, and the 201134558 liquid is washed through the opening of the bottom wall of the paint storage chamber. The supply port supplies a cleaning liquid to the paint storage chamber, and the cleaning liquid flows inside the paint storage chamber (the inside of the paint storage chamber is a piston positioned at a position slightly ahead of the deepest portion of the paint storage chamber) The specification is further discharged to the outside through the feed pipe. Patent Document 2 relates to the cleaning of the piston paint crucible, which points out the problem of the paint crucible of the above-mentioned Patent Document 1. As described above, the patent document proposes a piston A solution for cleaning the inside of the paint storage chamber defined by the piston at a position slightly earlier than the deepest portion. However, Patent Document 2 indicates that the problem is that in the method of Patent Document i, the paint E is passed. The flow of the cleaning liquid supplied to the paint storage chamber at the bottom of the cleaning liquid supply port causes the inside of the paint storage chamber to be uniformly washed. Patent Document 2, which particularly points out that it is difficult to wash off the paint entering the gap between the side surface of the piston and the side wall of the paint accommodating chamber, and it takes time to wash off the paint. Therefore, the problem of the literature 1 is Patent Document 2 proposes a solution in which a groove r extending in the radial direction toward a center portion of the bottom wall is formed in the bottom wall of the paint containing chamber.

Moreover, it is well known that in the painting of automobile bodies, it is effectively used on the arm. The coating robot for the electrocoating machine. For the piston coating crucible, as described above, the inside of the coating crucible (coating chamber) can be washed first, and then the paint of other colors can be filled to change the color of the coating crucible. In the case of performing a color change to wash the paint accommodating chamber of the paint enamel, it is also clearly disclosed in Patent Document 2 that the piston system is positioned slightly away from the bottom wall of the paint accommodating chamber. This means that the paint is contained for washing. The room must specifically allow a certain amount of paint to remain in the paint containment chamber, and the residual paint will be disposed of together with the cleaning solution. If only one color change is considered, then the paint remaining in the paint containment chamber can be said ( The amount of the discarded paint is small, but the amount of the discarded paint will become enormous at the site where a large number of automobile bodies are painted. Therefore, it is required to try to reduce the amount of the paint that has been disposed of in one color change as much as possible. As described above, the paint crucible can be roughly classified into a piston type and a bag type. However, compared with the bag type, the piston type mechanism is complicated, and in order to make the piston smoothly move in the coating step, it is necessary to perform around the piston. maintain. Therefore, the piston type coating has a coating which is not only expensive to manufacture than the bag type coating, but also requires the cost and labor disadvantage of the maintenance of the coating. On the other hand, the bag type coating material is reused. That is, if it is assumed that the material of the coating machine is unloaded, it is necessary to fill the coating of the A color, and it is limited to the coating of the same color that is fresher than the coating of the coating bag. Paint in the enamel. The inventors of the present invention have proposed the present invention, that is, the manufacturing cost is low and the maintenance is focused on the advantages of the bag type paint crucible described below, and the bag type paint is easier than the piston type paint. The purpose of the invention is to provide the right to supply the enamel®, which is used to clean the interior of the paint enamel in order to change color, and to reduce the amount of paint discarded during the cleaning. . The object of the present invention is to provide an electrostatic coating machine which reduces the amount of discarded paint and simplifies the coating machine when the electrostatic coating machine and the coating material are color-changed to wash the inside of the coating belt. Wash the body.

Other objects and advantages of the present invention will become apparent from the following description of the preferred embodiments. [Embodiment] Hereinafter, preferred embodiments of the present invention will be described based on the drawings. The drawing is used to illustrate the outline of the electrostatic coating machine that has been mounted on the painting robot. In the first picture, the representative of the household is _, and the child 1 shows the arm of the painting robot. At the front end of the robot arm 1, the 餹番+壮电涂机2 is installed. The electrostatic coating machine 2, 201134558 is an example of a rotary atomizing coating machine having a bell cup 4 as a paint atomizing device (a paint atomizing means). However, for a spray coating machine, The invention is also applicable. Electrostatic coating machine 2 is a paint coating machine. Specifically, the electrostatic coating machine 2 includes a coating machine main body 6 that is fixed to the front end of the robot arm 1 and a paint E 10 that is to be mounted (mounted) on the upper end surface of the coating machine body 6 It is the opposite side of the bell cup 4. This coating material 可1 is detachable with respect to the coating machine body 6. The paint crucible 10' has a paint pouch 12 which constitutes a paint containing chamber for filling the paint. The paint bag 12 can be pressed by applying pressure to the paint bag 12 from the outside to forcibly reduce the volume of the paint storage chamber formed by the paint bag 2 to supply the paint of the paint bag 12 to the paint. The machine body paint crucible 10 has a sealed space 14 in which the paint bag 12 is housed, and this sealed space 14 is formed by the outer casing 16. The outer casing 16 is preferably made of a transparent or translucent hard material, and a typical outer casing 16' is made of a transparent or translucent plastic material. This coating is used as a means of applying pressure directly to the coating bag 12 by using the working fluid. Therefore, the periphery of the paint bag 12 must be filled with the working fluid. The activator is preferably an insulating liquid; typically, an insulating diluent is used as an activator. The liquid in the space (14) constituting the liquid-repellent chamber is not required to be mixed with the space a'. Therefore, in order to capture the vacant rolling in the sealed space 14, the air accumulator 14a having a convex shape is provided at the top of the sealed space 14. 12 201134558 Figure 2 is a front view of the paint bag 丨2. The paint bag 丨 2 is a tubular soft plastic molded article that is opened up and down. As will be described in detail with reference to Fig. 2, the heavy bag 12 has a tubular bag body 12' that extends upward and downward, an upper port portion i2b that extends upward from the upper end of the bag body 12a, and a self-bag body I. The lower port portion 12c whose lower end extends downward. That is, the paint bag 12 is opened up and down by the mouth portions 12b and 12c of the upper end and the lower end. The paint bag 12, the upper knitting portion 12b and the lower port portion 12c are fixed to the paint cartridge 1 and laterally press the bag body 12a of the bag body coating titanium 12 by the driving liquid supplied into the sealed space 14. The corner portion between the upper port portion 12b and the lower port 4 12c is formed into a smoothly curved shape. ^ However, the coating bag is made by hot-melting two soft sheets. The paint is easy to adhere to the inner surface of the paint bag. The i of the paint, this point can be said to have been considered. From this, it can be seen that the previous bag type paint enamel was only used for re-use of the same color paint, and the idea of reusing the inside of the paint bag was not used at all. The paint bag 12' of the embodiment is a molded article made of a secret material which is produced by using a molding die, and the inner surface of the paint bag 12 is composed of a surface which is seamless and flat. The material of the paint bag 12 of this embodiment is a low-molecular poly-r, knee, and 丄θ m, because it is made by blowing and forming a soft and soft dream*. A preferred material is low molecular weight polyethylene. A low-molecular-weight polyethylene, which is a long-lasting resin material, is durable in the interior of the wash paint bag 12, and the paint bag 12 is reused in the evening. It is required. 13 201134558 Of course, the material of the coating, the material and the forming method of μ u 八 2 are not limited to the above-mentioned low olefin # popularity forming. In order to wash the inside of the paint bag 12 and the amount of paint discarded when it is washable, the characteristics of the paint bag 12 are (1) at least moderate flexibility of the bag body 12a, (2) water-repellent inner surface, and f with && () seamless and smooth inside. Therefore, as long as this condition is met, paint dreams! . The forming method of M _L, , , or the resin material can be arbitrarily selected. Further, it is possible to apply the treatment to the inner surface of the coating bag 12 to impart properties such as the internal water repellency of the coating bag 12, seamlessness, smoothness, and the like. For example, the nylon resin fluorinated ethylene propylene sulfide copolymer (FEP) is a resin material having excellent chemical resistance and excellent inter-slip property. Therefore, these resins can be used to make "paint bags. 12. Further, for example, the inner surface of the paint bag 12 may be coated with an FEP material. As a method of treating the inner surface of the coating bag 12, for example, a coating method, a lining method, and a resin distillation method can be listed. X, it is also possible to form a coating on the inner surface of the coating bag u by "impregnating the coating material into a liquid of a suitable resin material. The coating bag 12 of the second drawing as described above is designed to be: by lateral pressure The bag body i2a' is extruded and the paint is extruded from the lower port portion 12c. When the crushing property of the bag body 12a is improved, if necessary, it may be as shown by the broken lines in Fig. 2 and Fig. 4, in the bag body 12aJl. The singular or plural longitudinal ridges 12d extending in the longitudinal direction of the bag body (1) are integrally formed. The paint bag 12 constituting the paint accommodating chamber can at least make the bag body transparent or translucent. 12a is transparent or translucent, and has the advantage of visually confirming the color of the paint or the filling of the paint in the bag body 12a from the outside. Moreover, it is easy to find the case of the damage of the paint bag 12 and causing the paint to leak out. The premise of this advantage is 'Forming the liquid-moving chamber casing 16 is transparent or translucent.

Further, a seal ring 404 is disposed on the outer periphery of the opening of the paint supply passage 44 at the bottom surface of the second recess 4〇2. Fig. 5 and Fig. 6 It means that the coating material is positioned in the body of the coating machine, at the location 40, and the coating device is fixed by the locking mechanism 42 (帛i diagram). The state of the main body 6 is attached. It should be noted that between the lower end surface of the section 'the cylinder and the bottom surface of the second recess 402, a seal 404 is interposed (provided). The segmented sleeve 300 is energized downward by the outer peripheral elastic force. Therefore, the lower end surface of the segmented sleeve 300 is defined by the coating 匣1 tamping 19 201134558 on the applicator body 6 The state in which the ring 404 is pressed. The first internal passage paint passage '2' of the paint E 10 and the paint supply passage 44 of the coater body 6; the joint portion of the drop 44 is sealed by the seal ring 404, so It is prevented that the paint flowing out from the coating 1 is wound around the crucible receiving recess of the coating machine body 6. 4 The second recess 402, thereby contaminating the recesses 40, 402. Fig. 5 is a view showing a state in which the i-th check valve 3 of the paint crucible 10 functions as a stop. In the state of Fig. 5, the i-th check valve 3 〇 functions as a check valve to prevent the paint from being applied. From the coating Τ κ iυ, the claws are out (the inner coating passage 20 is blocked). The other aspect 'the sixth figure shows the forced by the push rod% The movable valve body 304 of the first check valve 30 is pushed up to forcibly open the state of the first check valve 30. As described above, the push rod 74a is provided on the first body of the coating machine body 6. The actuator 74 is operated in conjunction with the third check valve 3A. The first actuator 74 is driven by air. In the forced open state shown in Fig. 6, the first check valve is used as an open/close valve. The movable valve body 3〇4 of 30 becomes detached from the valve seat 302, so that the paint of the paint bag 12 can flow out from the paint 匣1〇 through the inner paint passage 20 from the lower end opening 12c (the inner paint passage 20 is opened) . As described above, the paint cover 10 has a sleeve 3〇〇 which is vertically displaceable, and the sleeve 300 constitutes an outlet portion through which the paint in the paint bag 12 constituting the paint containing chamber flows out, and the sleeve 300 is self-contained. The lower surface of the paint 匣1〇 protrudes below and sighs. Further, here, the first check valve 30 is provided at the lower end of the sleeve 3''. Further, the movable sleeve 300 is energized (pressed) by the outer peripheral spring 3〇8 downward. On the other hand, the coating machine body 6 3 . The second recess of the smaller diameter portion (10) of the crucible 4. 2, the coating machine: the upper end of the coating supply passage 44, and the (four) 2 concave "knife opening" and a sealing ring around the opening ^ If the coating material is assembled to the coating machine body 6, the lower end surface of the movable sleeve 300 (the smaller diameter portion 3 of the knife Ua) is crimped to the dense _, thereby forming the paint outlet of the coating gl〇 The sleeve 3 is in a state in which the paint moving path 1 between the paint supply passages 44 of the body 6 is sealed by the seal ring 4〇4, thereby preventing contamination of the second recess from the paint flowing out from the 〇1〇. The wall surface of the crucible 2 or the like. The paint supply passage 44 of the coating machine main body 6 can be cleaned by the above-described configuration in a state in which the paint is attached. This advantage is not limited to the bag paint S of the embodiment. This advantage can also be achieved by using the previously known piston coating degree or by using the film coating disclosed in Patent Document 7, and therefore, for the piston type or the film type coating E, in particular, the feed is omitted. The coating structure composed of the tube has the advantages of adopting the above structure. Fig. 7 and Fig. 8 are for forcibly opening the coating 匣1〇 The second check valve 32 of the second internal passage (actuating fluid supply passage) 22 is a detailed view of the second actuator 76 provided in the coating machine main body 6. The 帛2 actuator 76 is made of air. When the pusher 76a advances and retracts, the pusher 76& advances, and the movable valve body 32 of the second check valve 32 can be forcibly separated from the valve seat 322 (Fig. 8). The i actuator 74 and the i-th check valve 30 are the same, however, in the following, the second actuator % of the attachment rod 76a adopts a characteristic structure. 21 201134558 That is, the second actuation of the coating machine body 6. The push rod 76a of the device 76 not only has a function of forcibly moving the movable body 320 of the second check valve 32 from the valve seat 322 by the upper end surface thereof (Fig. 8), and the push rod 76a also constitutes an opening and closing coating. A part of the opening and closing valve mechanism of the operating fluid supply passage 50 of the main body 6. Referring to Fig. 7, the push rod 76a is formed by the π portion of the working fluid supply passage 50 (facing the g receiving recess 4) The sleeve 500 of the (moving liquid outlet portion) is surrounded by a valve seat 5 formed on the inner peripheral surface of the upper end portion of the sleeve 5〇〇. On the other hand, the push rod 76a is formed with a valve body protruding in the radial direction at the upper end portion thereof. The valves I 5 () 2 and the wide body 5 〇 4 ' constitute an actuating liquid for opening and closing the coating machine body 6. The opening and closing valve mechanism 506 of the outlet portion of the supply passage. In Fig. 7, the valve mechanism 5〇6 is opened and closed, and when the push rod 76& is displaced upward, the valve body 5〇4 integral with the push #76a is self-closing The seat 5〇2 leaves and opens. As described above, when the push #76a is displaced upward, the paint is forcibly opened... The second check is 32 (the arrow symbol of Fig. 8). When the push rod 7 6 a is downward # Hair: n when the valve moves, the valve body 504 is inserted into the valve seat 502

Then, the opening and closing valve mechanism 506 is set to A M , and the θ war is closed. Of course, by the retreating action of the pusher 76a, the second check valve 32 of the paints s, 10 will function as a check valve, because the second check valve 32 is used to prevent the action. The liquid leaked from the paint 匣1〇. At the bottom end portion of the push rod 76a (the lower end portion of the drawing of the first stage 7), a flange 78 is fixedly provided, and the flange 78 is energized downward (pressed) by the elastic spring 80. The push rod 76a is always energized downward by the bullet. As a result, the opening 22 201134558 valve closing mechanism 506 is energized (pressed) by the spring 80 in the valve closing direction. According to the above configuration, in the process of attaching the coating material S 10 to the coating machine main body 6, even if the coating material s 1G is fixed to the coating machine main body 6, as long as the second actuator 76 is not operated, the liquid is moved ( The insulating thinner does not leak from the coating body 6. Of course, in the coating container 1, the actuation liquid (insulating diluent) can be prevented from leaking from the sealed space 14 (actuating liquid chamber) by the third check valve 32. Returning to Fig. 1 again, the operation of the electrostatic coating machine 2 in the coating step will be described with reference to this. In the painting step, the first and second actuating thieves 74 and 76 operate, and the pushers 74a and 76a advance, whereby the pusher W advances to the second stop call 32 and is maintained in the forced opening. State (H material 2G and (4) Actuator supply passage 22 "+/γ· λ Release 1st check valve 30 (E inner paint passage) forcibly open; 2nd check valve 32 (within the actuating liquid supply passage) Strong, y -, -,,.yu \J, the passage switching valve 58' can control the straightening of the actuating liquid (diluent) supplied to the coating E1, and 'by applying the liquid to the coating E10 The pressure 'by this allows the paint to be in a controlled state: bag 12, outflow. Gear pump 56 opening/closing or passage switching 丨: path switching action' is with the opening of the trigger valve 46 of the cracker body 6. By this, it is possible to improve the control accuracy of the supply and supply stop of the paint for the bell cup 4. 23 201134558 At the time of completion of the coating of the special cup, the paint bag 12 constituting the paint storage chamber is completely crushed. At this time, the internal volume of the paint bag 12 (paint storage chamber) is the smallest, so it remains in the paint. The amount of the paint in the bag 12 is extremely small compared to the previous piston type paint 。. When the color change of the electrostatic coating machine 2 is performed, the paint 匣1〇 is replaced by the color of the coater body 6 and replaced with other colors. Before the coating of the coating material, the coating supply passage 44 and the bell cup 4 in the coating machine main body 6 are directly washed in a state in which the coating material 0i 0 is attached. Fig. 9 is a diagram showing the non-coating machine body 6 In the cleaning step, the coating supply path and the cleaning step of the bell cup 4 are directly washed in the state T in which the used coating material is mounted in the coating machine body 6. In the washing step When the operations of the first and second actuators 74 and 76 are released, the dry 4a 76a is retracted, whereby the jth and second check valves 3〇 and 32 function as a check valve to close the paint inside the crucible. The passage 20 and the actuating liquid supply passage 22. The washing nozzle 84 is inserted into the washing liquid supply passage 70 which is opened to the side surface of the coating machine main body 6. When the washing nozzle 84 is inserted into the washing liquid for supply At the entrance of the crucible, the fifth check valve 72' disposed at the inlet of the cleaning liquid supply passage 70 is forced by the cleaning nozzle 84. Opened. The operation of cutting the 86 by the passage of the Bu, the washing liquid or the air is self-cleaning under the pressure of the supply of the skin 7 to the cleaning liquid supply passage 7 于. In the cleaning liquid or air, The trigger valve 46 installed in the coating material supply passage 44 of the coating machine body is called the standing m. 4. Further, the bell cup 4 which is supplied with the cleaning liquid from the washing nozzle 84 is rotationally driven. 24 201134558 The state of the coating material supply passage 44 in the coating machine body is as follows. In the cleaning step, each valve (1) the first check valve 30 (paint) is strong and f is not read back, and the system is opened. Break release (pass (2) 2nd check valve 32 (actuator supply) (except for normal check valve function); | sweat release is solved j3) 5th check wide 72 (washing machine body cleaning) The nozzle 84 is cleaned and forced to open; (4) the valve 46 is opened by the trigger valve; (5) the bell cup 4 is rotated. The cleaning liquid or the air is supplied to the cleaning liquid of the coating machine body 6 under pressure to supply: the cleaning liquid is supplied to the body coating supply passage 44, and passes through the coating; 4 discharge. The coating machine, the road 44 and the bell cup 4 are cleaned by the passage 44 in the body coating supply passage 44, and the cleaning liquid and the air m are cleaned. Typically, the holes are alternately supplied from the cleaning nozzle 84. Up to the above, m Μ .

The cleaning liquid body 6 may be cleaned by the above cleaning liquid. The coating supply passage 7 is capable of purifying and coating the joint portion of the (4) 1G. Further, the front end portion of the sleeve 300 for constituting the coating outlet of the coating E 1 亦可 can be purified. This is a previously undiscovered advantage that should be paid attention to. Of course, the constitution for realizing this advantage is not limited to the bag type paint g, and can also be applied to the piston type coating and the membrane pump type. In addition, regarding the cleaning of the bell cup 4, if If necessary, the cleaning liquid can be dispersed from the outside to the bell cup 4" when the cleaning of the coating machine body 6 is completed, finally The self-cleaning nozzle 84 supplies air to the coating machine main body 6, thereby removing the cleaning liquid adhered to the coating material supply passage 44 and the bell cup 4 in the coating machine body. If the cleaning of the coating machine main body 6 is completed, Then, the paint cartridge mounted on the coating machine body 6 is replaced. Since the cleaning of the coating machine body 6 and the cleaning of the seal ring 404 are completed, it is only necessary to assemble the paint filled with the paint of other colors. Painting can be started again in the main body of the coating machine. 201126 201134558 The coating 匣10' that has been removed from the main body 6 of the coating machine is cleaned. The first drawing is used to explain the cleaning of the coating bag. A diagram of the steps. The finished paint 匣1 〇 is positioned at a specific location on the bag washing platform 88. This positioning is the same as the positioning for the coating machine body 6 'when the paint 匣 10 is positioned at a specific position, by The lock mechanism 90 fixes the paint cartridge 10. The bag cleaning platform 88 is provided with first to fourth pushers corresponding to the first to fourth check valves 30, 32, 34, and 36 of the paint cartridge 1匣. Actuator 8 80, 882, 884, 886. Actuator 880 of the first to fourth push rods The 886 functions substantially the same as the first unit 74, 76 of the above-described coating machine body 6, and therefore the detailed description of the coating bag 12' of the first coating S 10 placed on the bag washing platform 88 is omitted. In a state of being crushed, the cleaning of the paint bag 12 constituting the paint storage chamber is performed while the paint bag 12 is expanded to expand the volume of the paint storage chamber. (ii) The paint bag 12 is squeezed to reduce the paint. In the operation of the volume of the storage chamber, the cleaning liquid and the air are introduced into the paint bag 12, and the cleaning liquid and the air are discharged. The "expansion and compression" of the paint bag 12 is grouped, and the group can be executed once. That is to say, it can be repeated several times. Of course, if necessary, the coating 爰12 can be squeezed to the maximum extent before the coating bag 12 is washed to maximize the recovery of the coating remaining in the coating bag 丨2. The state of each of the opening and closing valves of the paint bag in the expansion step, that is, the check valves 3, 32, 34, 36, is as follows. (The forced opening of the first check valve 3〇 (paint) is released (normal check valve function); forced release of the second check valve 32 (actuator supply) 27 201134558 except (usually check back) (3) The third check valve 34 (washing liquid supply) is forcibly opened; (4) The fourth check valve 36 (actuating liquid discharge) is forcibly opened. Figure 10 is not for the bag washing platform. 88 is provided with an air source and a source (diluent or water), and the air source and the cleaning liquid source supply air 5 ^ The switching between the working gas and the cleaning liquid is performed by the passage switching valve 8 8 8 . The cleaning liquid is supplied to the paint bag 12 via the passage switching valve 888 and alternately passing through the third internal passage (cleaning liquid supply passage) 24 of the paint EU). As described above, the third check valve 3Q of the outlet of the paint bag η (the lower port portion (3)) functions as a normal check valve and is in a state in which the paint passage 2G is closed. The coating bag 12 is expanded by supplying air or paint from the upper port portion 12b' of the coating bag 12 to the inside of the coating bag 12 from the third internal passage (cleaning liquid supply path) 24 of the coating material S1G. Along with this, the actuating liquid 'filled in the sealed space 14 of the operating fluid chamber constituting the coating g 1〇 passes through the fourth internal passage 26 (actuating liquid discharge passage) opened at the air accumulator 14a, and is forcibly and passively Extrusion from the coating (7). The electrokinetic fluid extruded from the coating crucible 10 is recovered into the source of the working fluid. As a specific washing method of the coating bag 12, the following examples are mentioned. First step (expansion step of the paint bag): Air is supplied to the paint bag 12 through the third internal passage (cleaning liquid supply path) 24, so that the paint bag (four) "expands the internal volume of the paint bag U to a substantially maximum value" until. Thereby, the body 12a of the paint bag 12 can be brought to a state of no wrinkles. The i-th check valve 30 (paint) is off. Second step (cleaning liquid supply step): supplying the cleaning liquid to the paint bag 28 201134558 12 The cleaning liquid is caused to flow along the inner surface of the paint bag 12 to wash the paint bag i 2 . The first check valve 3〇 (paint) is off. The third step (pressing step of the paint bag): pressing the paint bag η to reduce the internal volume of the paint bag 12 to discharge the washing liquid of the paint bag 12. Repeat steps 2 and 3 as needed. The state of each of the opening and closing valves (returning 30, 32, 34, 36) of the paint crucible 12 in the above-described third step (pressing step) is as follows. (U first check valve 30 (paint) is forcibly opened; (2) second check valve 32 (actuating fluid supply) is forcibly opened; (3) forcible opening of third check valve 34 (washing liquid supply) Release (normal check valve function); (4) Forced opening of the 4th check valve 36 (actuating liquid discharge) is released (normal check valve function). As shown in Fig. 10, the bag cleaning platform 88 ± is provided with a gear pump 890. In the third step (compression step) described above, the amount of the actuating liquid is controlled by the gear pump _, and is supplied to the paint under pressure. The liquid is introduced into the paint IE H) In the sealed space 14 (actuating liquid chamber), the paint 12 is hydraulically squeezed by the operation, and the air and the washing liquid in the paint bag 12 are extruded to the outside through the lower port portion 12c. Reference numeral _1 indicates that the waste liquid tank's washing liquid extruded from the paint bag 12 is contained in the waste liquid tank 。. As described above, 'the expansion of the paint bag 12 (the enlargement of the internal volume of the paint bag 12) and the crushing (the reduction of the internal volume of the paint bag 12) are as follows: the group can be cleaned by applying the group or repeating the plurality of times. The inside of the bag 29 29 201134558. Further, finally, air is poured into the paint bag 12 to discharge the washing liquid adhered to the inside of the paint bag 12, whereby the washing step of the paint bag 2 is completed. At the stage where the washing step of the coating bag 12 is completed, the coating bag 12 is in a state of being crushed (the state in which the internal volume of the coating bag 12 is the smallest). The paint 匣 10 ′ which has been cleaned of the paint bag 12 is then filled with paint into the paint bag 12 . Figure 11 is a diagram for explaining the steps of filling the paint. The washed paint 匣 1 〇 is positioned at a specific position of the paint filling station 92. This positioning is the same as the coater body 6 or the bag washing platform 88, and the paint tamper 10 is fixed by the locking mechanism 94 when the paint cartridge 10 is positioned at a specific position. The first to fourth check valves of the paint crucible 10 are provided on the paint filling stage 92 except for the second check valve 32 related to the supply of the hydraulic fluid and the third check valve 34 related to the supply of the cleaning liquid. Actuators 92〇, 922 of the fourth and fourth push rods corresponding to the i-th and fourth check valves 3〇, 36. The actuators 92 and 922 of the fourth and third push rods have substantially the same functions as the actuators 74 and 76 of the first and second push rods of the coating machine main body 6, and therefore are omitted. Its detailed description. Each of the on-off valves in the paint filling step is the state of the check valves 3, 36, as shown below. (1) The first check valve 30 (paint) is forcibly opened; (2) the fourth check valve 36 (actuating liquid discharge) is forcibly opened. In order to fill the paint source paint under pressure into the paint bag Η _, a gear spring 96 is disposed on the paint filling station 92, and the gear pump 96 is controlled by the fine field to pass a specific amount of paint through the paint bag 12 The mouth portion 12c is filled into the coating bag 30 201134558. The flow control of the gear pump 96 can also be replaced by a combination of a flow meter and a flow control valve for controlling the supply of the pump from the pump under pressure. The amount of the paint of the bag 12 is such that after the amount of the paint measured by the flow meter reaches a certain value, the supply of the paint to the paint bag 12 is stopped. The paint bag 12 is expanded by the filling of the paint, and thus is filled with the seal. The moving liquid of the space 14 is discharged to the outside through the air accumulating it 14a and the fourth internal passage (actuating liquid discharge passage) 26, and the actuating liquid is recovered to the actuating liquid source. Of course, since the coating is filled After the coating is finished, the color of the coating filled into the coating can be any color. The coating filled with the coating is 匣1〇, and is stored for the next coating. When the insulating diluent is used as the working fluid, the embodiment "when a conductive liquid such as water is used as the working fluid, the pressure lock mechanism can be placed in the robot arm i" when the electrostatic coating machine 2 is used. When a voltage is applied (coating operation t) 'electrical insulation is performed by the electric M lock mechanism. The above describes the embodiment of the present invention, but the present invention is not limited to the embodiment' and includes the following variation 4 Check valves 30 to 36 (1) The air-driven opening and closing valve is installed in the paint crucible.
