Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for applying a coating agent such as a primer, paint, or adhesive.

[Conventional technology]

Conventionally, there are two methods for applying coating agents: one is to move a brush impregnated with the coating agent against the material to be coated, and the other is to hold the tip of the nozzle a certain distance away from the surface of the material to be coated. A commonly used method is to move the agent while discharging or spraying it from the nozzle.

For example, as shown in FIG. 14, when applying black primer BP to the hinge-attached parts Gl and G2 of the quarter glass QG on both sides of the rear seat of an automobile, the surface F1 is applied to the respective parts CI and G2. , the back surface F2, and the end surface F3 (see FIG. 1), which must be coated on a total of three surfaces (see FIG. 1). Conventionally, this was done with a brush.

[Problem to be solved by the invention]

Therefore, when applying the respective portions Gl and G2, it is necessary to move the brush to the quarter glass QG three times, and each time, it is necessary to move the brush to the quarter glass QG.
Since it is necessary to change the orientation of the quarter glass QC, such as by turning the glass upside down, the coating process requires a lot of time and effort.

This is a method of applying a coating agent.

The invention according to claim 2 uses a stretchable coating member that can be impregnated with a coating agent, and the coating member is constituted by at least two coating parts that are movable independently of each other, and Application of a coating agent, characterized in that the application member is moved along the application surface of the material to be coated while pressing each application portion impregnated with the coating agent against two application surfaces. It's a method.

The invention according to claim 3 is a chuck means having two claw members that can be opened and closed, and made of a stretchable material that can be impregnated with a coating agent, and a coating portion corresponding to the coating surface of the material to be coated is formed. and an applicator member attached to each of the claw members;
A coating agent coating device comprising: a coating agent supply means for supplying a coating agent to the coating member; and a manibrake means for relatively moving the chuck means along the material to be coated. It is.

[For production]

The application member is supplied with the application agent, and furthermore,
When applying with a brush, the application trajectory changes each time, so it is not easy to apply uniformly within a predetermined area, and the application pattern is not constant, resulting in the application of unnecessary parts. There are also problems in wasteful consumption of the coating agent and appearance after coating, such as uneven coating.

In view of the two problems, the present invention provides a coating agent coating method that can coat two or more surfaces at the same time, shorten the time required for coating, and make the coating pattern constant. The purpose is to provide such equipment.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the invention of claim 1 uses a stretchable application member that can be impregnated with a coating agent, and uses the surface of the application member to coat the material to be coated. A coating portion corresponding to the coating surface is formed, and the coating member is moved along the coating surface of the coating material while the coating portion impregnated with a coating agent is pressed against the coating surface of the coating material. The interior of the coating member is impregnated with a coating agent, and the coating portion of the coating member is bent by pressing against the coating surface of the material to be coated.

In this state, the coating agent is applied to the coating surface of the material to be coated by moving the coating member along the coating surface.

When the coating member is constituted by at least two coating parts that are movable independently of each other, it is possible to simultaneously coat a plurality of coating surfaces of the material to be coated.

Two claw members are attached to the chuck means,
Each claw member is attached to an applicator member in which an applicator portion corresponding to the application surface of the material to be applied is formed.

The mani break means moves the chuck means to a predetermined position close to the material to be coated, and in this state, the chuck means pinches the coating surface of the material to be coated. This brings the application section into pressure contact with the application surface.

By supplying the coating agent by the coating agent supplying means, when the chuck means is moved along the material to be coated by the manipulator means, coating is performed on the coating surface according to the movement locus.

5 reaches a position slightly (approximately 1 mm) from the front surface Fl (back surface F2) and end surface F3 of the quarter glass QG, and therefore, the flat coating section 34 and the end surface coating section 35 are applied to the surface Fl of the quarter glass QG. (the back surface F2) and the end surface F3, it bends and is in a state of being pressed against the respective surfaces. In addition, the lower coated felt 2
3 also opens and closes in the same way as the coated felt 23 above, so the tips of the protrusions 35a of these coated felts 23 also come into contact with each other and bend.

Note that the coated felt 23 can also be made using a porous material such as cotton, cloth, cotton covered with cloth, or sponge.

As particularly shown in FIG. 5, the felt holder 22 is composed of symmetrical holder members 22a and 22b that are divided into left and right halves, and these are molded from, for example, synthetic resin. . These holder members 22a and 22b have a recess 38 into which the coated felt 23 fits, a recess 37 of the coated felt 23,
Two coated felts 2 provided independently from each other at 31
3 is pressed against the front surface F1, back surface F2, and end surface F3 of the quarter glass QC, and in this state is moved along the quarter glass QG by the manipulator 5a, and the portion Gl
, G2 will be coated with blank primer BP.

Next, the coating agent supply jig 12 for supplying the black primer BP to the coating jig 13 will be explained.

7 is a plan view of the coating agent supply jig 12, FIG. 8 is a cross-sectional view of the coating agent supply jig 12 of FIG. 10 is a cross-sectional view taken along the line X--X of the coating agent supply jig 12 in FIG. 7, and FIG. 11 is a side view of the coating agent supply jig 12 in FIG.
- It is a sectional front view taken along the line XIX.

The coating agent supply jig 12 includes a main body block 51, a supply felt 52, a felt cover 53, and a felt cover holder 5.
4, and a packing 56.

Engaging protrusions 39, 39 (see Fig. 2) that engage and prevent removal are each formed with a protrusion 40 that fits exactly into the groove 31 of the jig main body 21 on the outside thereof. .

The felt holder presser 24 is made of a thin metal plate, and the central portion and both side portions of the tip are bent in opposite directions to form a locking portion 41 and an operating portion 42, respectively. The felt holder presser 24 is fixed to the jig body 21 by bolts 25, and in this state, the locking part 41 locks the tip of the felt holder 22 inserted into the groove 31 of the jig body 21. When removing the felt holder 22, the locking portion 41 is prevented by pushing the operating portion 42 upward from the front.
All you have to do is release the lock.

Since the coating jig 13 is configured as described above, when the upper coating jig 13a and the lower coating jig 13b are closed by the parallel opening/closing movable chuck 14, each coating jig 13a, 13b has a The main body block 51 is made of a metal material and has a substantially U-shape in plan view, and has a groove 6 in the center of the inner surface into which the supply felt 52 is fitted.
1 has recesses 62, 62 on the upper and lower surfaces along the inner edge for mounting the packing 56, and symmetrical U-shaped grooves on the lower end surface in FIG. 8 for mounting the felt cover 53. 63, 63 are formed, respectively.

Also, as shown in particular in FIGS. 8 and 10,
A large number of outflow holes 64, 64... which open from above are formed in the inner peripheral upper surface 61a of the groove 61.
4 is formed with a port 67 communicating through communication holes 65, 65 and a communication hole 66. These outflow holes 64 and communication holes 65 and 66 are easily formed by drilling holes of appropriate depth from the outer peripheral surface of the main body block 51 and inserting blind plugs into the outer peripheral surface.

The inner diameters of both communication holes 65 and 66 are the same, but the outflow hole 64
The inner diameter of the communication hole 65 is narrowed to about half the inner diameter of the communication hole 65, so that when the black primer BP is supplied from the boat 67, the black primer BP is jetted almost uniformly and vigorously from each outflow hole 64. It is designed to flow out like this.

The main body block 51 also has mounting holes 68.6.
8... is provided.

The supply felt 52 is made of the same material as the coating felt 23 described above or a spongy material softer than the coating felt 23, and has a rectangular shape and a thickness that fits into the groove 61 of the main body block 51. It has the same plate shape as Saga Quarter Glass QG.

The felt cover 53 is for preventing the supply felt 52 from being pulled out from the groove 61, and has two felt covers that fit into the grooves 63, 63, which are shaped like openings formed on the end surface of the main block 51. It consists of cover members 53a and 53b.

Each of the cover members 53a and 53b is the same and is mounted in a state where it is rotated 180 degrees with respect to each other.
The black primer BP flows out in a jet form from the upper surface of the supply felt 52 and penetrates into the interior thereof from the upper surface of the supply felt 52, and diffuses inside the supply felt 52. In some cases, the black primer BP that cannot be completely diffused is removed by the main body block 51 of the supply felt 52. The overflowing black primer BP overflows onto the upper surface of the uncovered exposed portion 52 a and subsequently soaks into the inside of the supply felt 52 or the supply felt 52
It soaks directly into the coated felt 23 sandwiching the .

Therefore, the supply felt 52 is not impregnated with the black primer BP only in the lower part due to its gravity, but is impregnated all over, and in particular, the portion that comes into contact with the application felt 23 of the application jig 13 and supplies the black primer BP. 52a.

Next, the coating agent supply device 3 that supplies the black primer BP to the coating agent supply jig 12 will be explained.

FIGS. 12(a) and 12(b) show the convex portion 6 of the coating agent supply device.
9 and a vertical groove 70 into which the felt cover holder 54 is fitted are formed.

The felt cover presser 54 is made of a thin metal plate similar to the felt holder presser 24 described above, and its tip portion is bent at 90 degrees to form a locking portion 71. The felt cover retainer 54 is fixed to the main body block 51 by bolts 55, and in this state, the locking portions 71 fit into the vertical grooves 70 of the cover members 53a and 53b from above and below, and the above-mentioned cover members This prevents 53a and 53b from falling off.

As shown in FIG. 6, the coating agent supply jig 12 is fixed to the mounting block 15 attached to the base 2a of the coating device 2 by inserting a bolt (not shown) into a bolt 68 formed on the main body block 51. In addition, black primer B is supplied to the boat 67 from the coating agent supply device 3.
Plumbing is provided to supply P.

When black primer BP is supplied to port 67,
Black primer BP is a fluid circuit diagram of communication hole 66°3. However, this figure shows parts that are not built into the coating agent supply device 3, such as the coating agent supply jig 12 and the coating jig 1.
3 are also shown.

The coating agent supply device 3 includes an adjustment section 81 for supplying clean air whose pressure is properly adjusted, and a supply section 82 for supplying the black primer BP using the pressure of the air.

The adjustment unit 81 includes a receiving port 83 into which air is input from a compressor (not shown), and an auto-drain filter 8.
4. Regulator 85 for rough adjustment of pressure, pressure gauge 86, air dryer 87 for removing moisture, regulator 889 for fine adjustment of pressure in normal air line LNI and cleaning air line LN2, respectively.
2. Pressure gauges 89, 93, stop valves 90, 94, and
It is comprised of a switching valve 91 for switching air from both air lines LN1.2 and the like.

The supply unit 82 includes a solvent tank 95 containing an anti-hardening solvent SE, a stop valve 96, a pressure gauge 97, a primer tank 98 containing a black primer BI), and a liquid of black primer BP in the primer tank 98. It is composed of a liquid amount detection sensor 99 that detects the amount of liquid.

The air dryer 87 lowers the temperature of input high-temperature air, discharges and removes condensed water, lowers the dew point to about 0 degrees Celsius on the liner, and prevents condensation in subsequent lines. It is of a known structure in itself, incorporating an exchanger, a pre-filter, a final filter, an automatic drainer, etc. However, by using this air dryer 87, the Frankfurt.

There is no fear that Limer BP will react with moisture and harden, and there is no need for special piping for nitrogen gas, unlike in the case of conventional high-pressure nitrogen gas.
Since the pressure difference is small, precise pressure adjustment is possible, and there is no need to replace the high pressure tank filled with nitrogen gas. Further, since the flow rate required for applying the black primer BP is small, the cartridge-type primer container 127 filled with the black primer BP is removed from the inner peripheral surface 127a at the bottom thereof. is positioned and placed so as to fit into the outer peripheral surface 119a of the convex portion of the base 119.

A pipe 122 connected to the primer line LN8 via a connector 121 and a liquid amount detection sensor 99 are each attached to the lid 117 in a sealed manner by screw-type bushes 120 and 123. The brimer tank 98 itself is attached to the attachment plate 3a of the coating agent supply device 3 via an attachment fitting 128 with bolts or the like (not shown).

The pressure inside the primer tank 98 increases as air containing solvent vapor flows from the air line L N 6 connected by the connector 126, and the black primer BP in the primer container 127 is pressurized. As a result, the black primer BP is fed under pressure from the primer line LN8 via the pipe 122, so that it can be handled by a small air dryer 87 and can be stored compactly.

As shown in FIG. 12(b), the solvent tank 95 has a cylindrical tank body 111 sealed with a lid 112, and the solvent SE is pressurized by air pressure from the air line LN5, and the solvent SE is pressurized by the air pressure from the solvent line LN7. The solvent SE is delivered from. Further, the air that has entered the solvent tank 95 flows out through the air line LN6 and flows into the primer tank 98. When the solvent SE is insufficient, the solvent SE is put into the hopper 113 and the stop valve 96 is opened to replenish the solvent.

114 is a safety valve.

As shown in FIG. 13, in the primer tank 98, a tank body 116 is constructed by integrating a bottom plate 115 and a tube 116a, and the upper opening of the tank body 116 is removable by a clamp device 118118... It is sealed by M117 attached to.

On the bottom plate 115 is a pedestal 119 made of synthetic resin or the like.
is placed on the pedestal 119 to prevent the black primer BP from curing.

The liquid level detection sensor 99 has a thermistor sealed at its tip (lowest end), and a constant current is supplied to the thermistor from the lead wire 125.
It is configured to detect a change in the heat dissipation state due to the presence or absence of P as a change in resistance value due to a change in temperature of the thermistor. This liquid amount detection sensor 99 detects that the black primer BP in the primer container 127 is empty.

When the black primer BP in the primer container 127 is empty, the air from the air line LN6 is stopped to release the pressure in the primer tank 98, and then the clamp device 118 is operated to remove the lid 117 and the black primer BP is removed. Replace with a new primer container 127 that is filled with primer, shaken well, and has not settled.

Therefore, replenishing the black primer BP to the primer tank 98 is extremely easy, and each time the primer container 127 is replaced, it can be shaken so that the black primer BP does not settle. If the primer container 127 has not been used for a long period of time, it can be easily taken out from the primer tank 98 and shaken, so that the concentration of the black primer BP pumped from the primer line LN8 becomes uniform, making it easier for subsequent applications. This is very convenient and does not result in a concentrated liquid of black primer BP remaining at the bottom of the primer container 127, which is uneconomical.

Now, in FIG. 12(b), the primer line LN
The black primer BP pumped from the switching valve 101 and the solvent SE pumped from the solvent line LN7 are connected to the switching valve 101.
A pilot operated switching valve 102 which is switched by
When the electromagnetic switching valve 103 is switched, the coating agent is supplied to the boat 67 of the coating agent supply jig 12 via the supply line LN9. In addition, the air supplied by the air line LN3 is input to the above-mentioned switching valve 103, as well as to the regulator switching valve 10.
1 is located at a position connecting the primer line LN8 to the supply line LN9.

The coating robot 5 first causes the coating unit 11 to approach the coating agent supply jig 12 using the manipulator 5a with the parallel opening/closing drive chuck 14 open, and the switching valve 105 is switched by a signal from a control section (not shown). As a result, as shown in FIG. 6, the parallel opening/closing drive chuck 14 is closed, and the application felts 23 on the upper and lower sides of the application jig 13 sandwich the supply felt 52 of the coating agent supply jig 12. At this time, the contact portions of the application felt 23 and the supply felt 52 are pressed against each other and are bent, so that the black primer BP easily penetrates from the supply felt 52 into the application felt 23. In addition, the inner surface of the jig main body 21 has a packing 5.
6, whereby the supply felt 52 and the application felt 23 are in a state of being cut off from the outside air.

In this state, by turning on the switching valve 102 for a certain period of time T1, the black primer BP is
is input to the parallel opening/closing drive chuck 14 via the bows 1 to 6104 of the coating agent supplying jig 12 and the electromagnetic switching valve 105, and the switching valve 105 is controlled on/off to cause the parallel opening/closing drive chuck 14 to perform opening/closing operations. conduct.

The switching valve 101 and the switching valves 102 and 103 are arranged near the coating agent supply jig 12, and the regulator 104, the switching valve 105, and the pressure gauge 106 are arranged near the coating agent supply jig 12.
is placed near the coating robot 5. Therefore, the line 6 in FIG. 14 is composed of an air line LN3, a solvent line LN7, a brimer line LN8, and other electrical signal lines.

Next, the operation of the coating system 1 configured as described above will be explained.

The pressure in each part of the fluid circuit is set to approximately 7 kg/cffl by the regulator 85 and approximately 0.0 kg/cffl by the regulator 88.
It is adjusted to 1 to 0.5 Kg/cIiI and approximately 2 Kg/cdl by the regulator 92, respectively. The switching valve 91 is normally located at a position connecting the air line LN1 to the air line LN5.

7, the black primer BP flows out from the outflow hole 64, completely soaks into the supply felt 52, and sufficiently soaks into the application felt 23.

After a certain period of time T2 has elapsed since the switching valve 102 was turned off, the switching valve 105 is switched to open the parallel opening/closing drive chuck 14, and the manipulator 5a moves the coating unit 11 into the quarter position, as shown by the chain line in FIG. The glass QG is applied to the part G1, and then the first
As shown in the figure, the parallel opening/closing driving chuck 14 is closed, and the coating felts 23 on the upper and lower sides of the coating jig 13 sandwich the front surface Fl, the back surface F2, and the end surface F3 of the quarter glass QC.

At this time, the flat surface coating portion 34 and the end surface coating portion 35 of the coated felt 23 are pressed against the quarter glass QG and bent, and the black primer BP impregnated in the coated felt 23 is bent.
seeps out.

At the same time, by moving the application unit 11 parallel to the quarter glass QG using the manipulator 5a, the black primer BP is uniformly applied on the front surface F1, the back surface F2, and the end surface F3 of the quarter glass QG with a constant coating trajectory. It is applied in (shape).

When the application of the portion G1 is completed, the parallel opening/closing drive chuck 14
, and then apply part G2 in the same manner as described above.
When the application of the portions Gl and G2 is completed, the manipulator 5a
moves the coating unit 11 to the position of the coating agent supply jig 12 again.

Then, the next quarter glass QG is positioned at the coating position by the conveyor 4, and the same operation as described above is repeated thereafter.

The amount of black primer BP impregnated into the coating felt i 23 by the coating agent supply jig 12 is
2, that is, the total amount of black primer BP supplied from the port 67, the impregnation of the coated felt 23 is determined by keeping the time T1 during which the switching valve 102 is turned on constant. The amount (that is, the amount of coating on quarter glass QG) can be easily made uniform, and the amount of coating can be easily adjusted by variably adjusting the time T1.
etc., to prevent clogging and malfunctions. In addition, the primer container 12 in the primer tank 98
Primer line LN8 can also be cleaned by replacing 7 with a container containing solvent SE.

In the above embodiment, the black primer BP is supplied to the coated felt 23 by the coating agent supply jig 12, but the black primer BP is supplied to the coated felt 23 by other supply means, for example, directly to the coated felt 23, without using the coating agent supply jig 12. A discharge nozzle may be provided to impregnate the liquid.

In the above embodiment, there are two coated felts 2 on top and bottom.
3 was used, but one continuous coating felt was used, and the edges at different locations were coated with the flat coating section 34 and the end coating section 3.
5, and these may be configured to be movable independently of each other so as to come into pressure contact with the front surface F1, back surface F2, and end surface F3 of the quarter glass QG, respectively. Further, the shape of the coating felt 23 may be changed in various ways depending on the surface shape of the material to be coated and the number of coated surfaces. For example, you can adjust quotas.

In other words, as in the past, quarter glass Q, which is the material to be coated,
When coating while supplying blank primer BP directly to G, the amount of outflow (discharge amount) of supplied black primer BP per minute unit time must be kept constant so that there is no fluctuation. When indirect supply is performed by pre-impregnating the coating felt 23 of the coating jig 13 with the coating agent supplying jig 12 as in the embodiment, the amount of the coating agent supplied to the coating agent supplying jig 12 per time is All you need to do is keep the total amount of black primer BP constant.
The control becomes extremely easy.

To clean the switching valves 101, 102, coating material supply jig 12, etc., switch the switching valve 91 to connect the cleaning air line LN2 to the air line LN5, and switch the switching valve 101 to supply the solvent line LN7. Line LN
Connect to 9.

As a result, the solvent SE in the solvent tank 95 is pressurized at a high pressure and flows into the equipment such as the transfer valves 101 and 102, and the surface F1 of the black glass QG that has adhered to the equipment
When applying only to the end face F3, only the upper application felt 23 is used, and the dimensions of the end face application part 35! 1 may be made equal to or longer than the plate thickness t1. Further, when coating a curved surface, the application portion of the coating felt 23 may be shaped in accordance with the curved surface. The curved surface may be divided into several parts and a plurality of coated felts 23 may be used. A plurality of coated felts 23 are applied to the entire circumferential surface of the columnar object.
may be made to correspond. The shape of the supply felt 52 may also be changed accordingly. The application felt 23 and the supply felt 52 may be made of different materials. In addition to black primer BP, it can be applied to various coating agents such as paints or adhesives.

In the embodiments described above, the fluid circuit of the coating agent supply device 3 can be modified in various ways. For example, if the filter 84 is replaced with a two-stage configuration of a coarse mesh filter and a fine mesh filter, even cleaner air can be obtained. Further, a switching valve for relief may be provided in the middle of the airline LN5.
