The rail 50 is fixed to a beam 50 fixed to the main frame of the coating machine. . FIG. 4 shows the container 2 supported by a holder 52 suspended from the cenograph 14. Here are some.

The "wetting" section 28 of the application/draining unit is made of polypropylene, which extends the length of the wetting section. It has a lower drain tray 54 made of a structural material such as pyrene. Above the lower tray 54 is supported below the container 2 via a unit device and is made of the same material as the lower tray 54. There is also a main drain tray or "recess" 56 that extends the length of the wetted area. . The applicator station 30 is located entirely above the recess 56 and is connected to the applicator station. Continued< At both train stations, turbulence and springs are present in the depressions. Less liquid paint falls that is not retained as a film on the container. In the recess 58 , with a break at the corner furthest from the coating station. This broken part has (No. 24). Cough is tanditsu It is discharged into the body weighing tank 82 through the tank 60. This is explained in Figures 23 and 25. The figures will be described in further detail. Liquid held in water distribution tank 64 (Figures 1 and 2) The main supply part for body paint is the normally closed stop valve 6B in Fig. 1 when the valve 6B is opened. 88 into the recess 56 and then through the weir 58 into the body weighing tank B2. to go into.

The recess 58 has a drain 70 with a normally closed dump valve 72, and the lower tray 54 as required. Excrete inside.

Reference is now made to FIGS. 1O and 12 which show details of the coating station. B Said chenor rail fixed to the chenor 50 is indicated by 74 above the chenor 14; Through a series of chain hangers 7B each movable along a rail by rollers 78. and supported by rails. The cheno hangers 7B are installed at equal intervals along the cheno. It will be done. On the opposite side of the cheno of each cheno hanger, i.e. on the bottom side, place the holder bracket A pivot bracket 80 having a bracket 82 pivoted about a horizontal axis is fixed.

One of the holders 52 is itself fixed to each bracket 82.

The extension portion 84 of each bracket 82 supports a rotatable driven roller 8B. coating At the cloth station, as shown in FIG. 1θ, the roller 86 is It engages with a rail 88 (application adjustment rail) fixed to the main frame, schematically indicated by 0. . The axis 80 of the holder 52 and the container 2 supported by the holder is It is tilted as shown by an angle of less than 80 degrees with respect to the vertical center plane 102.

In this position, the O-ring 82, which forms part of the holder 52, is painted as shown in FIG. It frictionally engages a drawbar 94 that passes through the cloth station. The tow bar 94 is a beam 50 by a bracket 86 while pushing the rod 94 towards the holder 52. It is supported by a bracket 96 via a spring 88.

Rigid mounting bracket) 104 is fixed to the main frame 100 and extends downward. There is. At its lower end, the bracket 104 is secured to the rear end of the stainless steel curtain plate 108. The curtain plate extends toward 102 in the center plane of the carrier chain, and The terminal edge, which is sloped into a thin string, is curved downward. As shown in Figure 10 In addition, the edge 108 of the curtain plate is located at the application station in or directly below the neck 4 of the container. The point on the outer surface of the container 2 that passes through the tube 30 is close to that point. Preferably curtains The lateral position of the plate can be adjusted, for example, by means of mounting screws 110.

The vertical position of the curtain plate is also adjustable by suitable means (not shown).

Bracket 104 also includes an adjustable tube clamp that holds nozzle 114. 112 is supported. This is the nozzle that delivers the paint into the container. That's the third As schematically shown in FIG. 4, it is connected to the body weighing tank 82 via the feed pipe 11B, Paint is delivered to the nozzle by feed pump 118 and variable regulating valve 12B. this are schematically shown in Figures 4 and 25, and their mounting positions may not be final. Instead, the pump 118 and the regulating valve 126 may be placed at arbitrary positions.

Nozzle 114 has a baffle plate directly behind its mouth. The nozzle opening is (tube (by adjusting the clamp 112 appropriately) 24, but of course it is not on the entire circumference of the nozzle opening. A gap 128 must be left to allow the material to escape from the nozzle, but if the nozzle opening If the contact point 122 with the curtain plate is at the top as shown, the paint will be applied downward and to the sides. It appears in the opposite direction, hits the back of the curtain board, and spreads. Then it flows down to the board, board 10B It should remain in the form of a liquid curtain hanging down from the lower edge lo8. A curtain like this The width, thickness, parallelism, etc. of the curtain are as shown in Figure 1θ and 130 in Figure 12. The characteristics of 130 can be adjusted by appropriately adjusting the flow rate using the main flow rate regulating valve 12B. It is determined.

Returning to FIG. 3, the detection rail preceding the coating adjustment rail 88 in the direction of movement of the check 714 132 is shown.

Detection rail 132 is further illustrated in FIG. This rail is located on the main frame of the applicator. fixed to the frame. The purpose is to tilt the container 2 into the position shown in Figure 10. That's true. The rail 132 has an infeed portion 134 parallel to the central plane 102 of the checker 7. However, it communicates with the second parallel portion 140 via the deflection portion 13B. This part is a rail through another section 142, which is also parallel to the plane 102. It leads to 144. A part of this transfer is placed on the short and small part of the coating adjustment rail 88. Overlap.

The operation of the detection rail 132 is illustrated in FIGS. 6-8. Figure 6 is The container 2 is shown at the point of first contact with the deflecting portion 13Ei, which deflects the container. Tilt outward into the position shown in FIG. held. When the container rides along the front section 2, its inclination angle is shown in Figure 8. When the roller 86 leaves the downstream end of the transfer section 144, It is smoothly and completely supported by the fabric adjustment rail 88. However, from holder 52 , as shown in Figure 9, when the container is empty, it misses the detection rail and closes the application station. The axis remains perpendicular throughout the via passage. In this way, the holder 52 is filled with liquid. Body paint will not splatter.

One construction of holder 52 is shown in FIGS. 13 and 14. Basically, Extremely simple configuration with two components: main body 14B and plunger! 4 8 is a flat body having a series of depending integral protrusions or pawls 152. It has a "pine mushroom" shape consisting of a disk-shaped base 150. Each pawl has a cross section A triangular (FIG. 14) outward facing profile fit behind the neck 4 of the container 2. The body 14B having the joint is made of structural polyamide (nylon) or other elastic plastic. It has a circumferentially grooved hollow stem which retains the O-ring 92.

This stem 154 is attached to the holder bracket 82 by a circular spring clip 158. Rotatably fixed within the hole. The plunger is shaped like a 148-momatsu room, Metal such as steel. This is a simple diagonal with a triangular notch that accepts the pawl 152. It is equipped with a disk-shaped head 158. The head 15B has approximately the same diameter as the main body base 150 It has an integral stem 160, is vertically slidable in the hole of the main body stem 154, and has an integral stem 160. It has a top end that engages with the protruding lamp 1B2 shown in FIG.

Referring to FIG. 18, lamp 162 is connected to unload station 40 (second In the figure), the bracket 7 is fixed to the beam 50 via the bracket 1B4. Supports container 2 When each holder 52 held reaches the lamp 162 and passes below it, the lamp is attached to the holder. plunger stem 180 of the container, thereby causing plunger 148 to hold the container. extrude from the router.

As shown in the 23rd factor and FIG. 25, the single-body weighing tank 82 is a part of an automatic batch weighing device. a nine-piece tank that continuously pumps liquid paint to the application station 30. The pump 62 in this example has a protruding portion at one end to which the pump 118 is attached as shown. 168 is attached to the tilt plate 18B. One end of the tilting plate 113B has a pair of It is attached to the heavy pivot 170. On the other hand, the tilt plate has a body tank shown at 172. The projecting portion is elastically supported by, for example, a pair of compression springs 174. It is. The spring 174 and pivot block 170 are attached to the block placed in the lower tray 54. It is secured to the lock 176 and to the main frame 100 of the applicator.

As already mentioned, the body tank 62 has a recess 5 through the tandish 60. The liquid paint is supplied from the weir 58 of 8. Then, the liquid level in the tank 62 reaches a constant maximum. The weight of the tank is insufficient to maintain the compression of spring 174 and the tilt 18B (not shown) activates the appropriate electrical switching means to activate the alarm. to notify that tank 82 must be reloaded. This operation is This is done by opening the valve 6B shown in FIG.

The switching means may be alternatively arranged to operate the means for automatically opening the valve 66, and may be arranged as appropriate. After the liquid level in the tank 62 reaches a certain maximum allowable value, ensure that the tank 62 is reclosed. to remind you that the water distribution tank (Figure 1) must be reloaded.

In operation, the carrier chain is continuously advanced and the liquid at the coating nozzle 114 is Continuously adjust the flow of the paint 130 and fill the container with the paint 130 as shown in Figure 1θ. - Continue to pass through. Adjust the liquid flow correctly to reduce the amount of liquid that traverses the curtain. The distribution is made even, and the film ( (as shown at 178 in Figure 1O) can be deposited up to a precisely regulated height. Ru. The container is rotated at least twice by engagement of the towbar with the O-ring 82. While being rotated three times, the container is in contact with the curtain 13G.

The difference between the configuration shown in Fig. 11 and the configuration shown in Fig. 1θ is that the holder is used as a tow bar. On the same side of bracket 182.

Here, the member 184 having a coating adjustment rail indicated by the reference numeral 180 has a coating adjustment rail. The same mounting secured to the rail 180 is connected to the rail 180 by a bracket 186. It is supported by many people. The roller 86 is supported by a short trunnion protruding from the bladder i82. be done.

Once the liquid paint curtain 130 is formed, the liquid may become excessive at the outer edges of the curtain. It gets cheaper. This is caused by or associated with turbulent flow of the liquid. Correct uniformity of coating and the exact position of the upper part of the film (178 in Fig. 1θ), i.e., the capacitance Turbulent flow must be avoided if surging of the liquid in contact with the vessel surface is to be avoided. Must be.

The modified curtain plate 18B shown in FIGS. 19 and 20 can be used if this problem occurs. Eliminate. Both ends of this plate 18B are notched at an angle from the horizontal plane as shown in the figure. This allows the liquid to spread at the outer edge of the curtain over the sloped portion 188 of the bottom edge 190. Reduce.

Next, referring to FIGS. 15 to 17 and FIG. 21, these are narrow No. 17 showing a modified example of the film of a container such as the PET bottle 191 shown in FIG. 21 having a neck portion. The figure shows another article with a narrow neck. In FIG. 21, the curtain plate 10B is The wide date container is the same as the one in Figure 10, but in this example the bottle is tilted. It hangs vertically as it passes through the coating station. This kind of situation In this case, the detection rail, application adjustment rail, and driven rollers such as roller 86 are not required. be. The narrow date container holder 192 is the same as the holder integral 146 in FIG. a generally cylindrical body 194 made of or similar elastic material, and a pine mushroom-shaped plunger. 0 cylindrical body 184 consisting of a simple combination with 200 is connected to the container neck 1 from the outside. It has an integral downwardly depending resilient pawl 198 that grips the handle 98 . Plunger 200 pieces It has a simple disk shape with a smaller diameter than the inner diameter of the plunger 136, and It has a head 202 that operates in exactly the same manner as previously described for 48.

Since the holder 192 does not have to be tilted, the tow bar 84 is placed here, also in the holder. It moves elastically in the horizontal direction to engage the O-ring 92 attached around the main body. The paint curtain is attached to the holder and the container supported by it. It rotates when passing through. The holder 182 is shown in FIG. Rigid bracket rigidly supported by carrier chain 14) 20B , are secured by spring clips 204. In Figure 21, the film height, The upper edge of the coating is indicated by 208. If this height must be made higher , the shape of the curtain plate is modified so that its lower edge is around the neck of the bottle as shown at 210. It can be located below the flange. This transformation takes place when the liquid Provided that there are no sudden changes in the profile that locally disturb the body. This is the time when a simple single-picture composition of curtain boards is unbeatable. Also preferably, - Turn the bottom edge of the balance plate downward.

As an example in FIG. 22, the coating height 212 is higher than the height 208 in FIG. In addition, the curtain plate 214 has a deformed profile with an S-shaped cross section, and the bottom edge 218 It opens into a short downward section 216 terminating at .
