The first application gun 2 in which the coating material is discharged only along the (parallel direction) is used, and as shown in FIG. The second coating gun 4 is used in which the coating material is discharged only along the direction orthogonal to the axis of the coating gun (the direction orthogonal to the displacement direction of the coating gun).

  As described above, conventionally, any one of the plurality of application guns 2 and 4 having different ejection directions with respect to the shape of the application site is appropriately selected and applied to apply the application material.

  In this case, the first passage 32a and the second passage 32b are connected to a coating material supply source (not shown) via a first switching mechanism (not shown), while the first air passage 34a and the second air passage. 34b is connected to an air supply source (not shown) via a second switching mechanism (not shown).

  The first switching mechanism (not shown) supplies the coating material to both the first passage 32a and the second passage 32b at the same time and either the first passage 32a or the second passage 32b. The case where the coating material is supplied (including the case where either the first passage 32a or the second passage 32b is selected) is appropriately selected and provided to be switchable. Further, the second switching mechanism (not shown) is configured to supply air to both the first air passage 34a and the second air passage 34b at the same time, and either the first air passage 34a or the second air passage 34b. The case where air is supplied to one side (including the case where either the first air passage 34a or the second air passage 34b is selected) is appropriately selected and provided to be switchable.

  A cylindrical portion 40 having an opening 36 into which the rod portion 26 is inserted is formed on one side surface of the gun body 12, and a male screw portion 38 is formed on the outer peripheral surface of the gun main body 12 to be engaged with the female screw portion 28 of the lock ring 30. Have.

  Further, the first main body 32 a of the rod portion 26 and the nozzle 20 of the first tip 22 are communicated with each other inside the gun body 12, and the coating material is supplied toward the nozzle 20 side of the first tip 22.

  Further, the first air passage 34 a of the rod portion 26 and the air discharge hole 44 of the first tip 22 communicate with each other inside the gun body 12, and air is directed toward the air discharge hole 44 of the first tip 22. The first air communication passage 46a for feeding the air, the second air passage 34b of the rod portion 26, and the air discharge hole 44 of the second tip 24 are communicated, and toward the air discharge hole 44 of the second tip 24. A second air communication path 46b for supplying air is provided.

  In this case, as shown in FIG. 3, the axis B of the air discharge hole 44 is set to be inclined by about 30 degrees with respect to the axis A of the nozzle hole 48 through which the coating material is discharged (inclination). Compared to the case where the angle θ is about 30 °) and the axis of the air discharge hole 44 is parallel to the axis of the nozzle hole 48, the width of the coating pattern can be widened to increase the area of the coating pattern.

  That is, as shown in FIG. 8, in the vertical gun 102 according to the comparative example in which the coating material is discharged only in the direction orthogonal to the axis of the gun body 100, the axis C of the nozzle hole 104 through which the coating material is discharged. And the axis D of the air discharge hole 106 are arranged in parallel to each other, so that the coating pattern width becomes narrow.

  On the other hand, as shown in FIG. 9, in the present embodiment, the axis A of the nozzle hole 48 that extends along the direction orthogonal to the axis of the gun body 12 and discharges the coating material, and the air discharge hole The 44 axis lines B are set to intersect with each other at an intersection angle of about 30 degrees. In other words, since the air discharge hole 44 is provided so that the incident angle is inclined by 30 degrees with respect to the axis A of the nozzle hole 48 through which the coating material is discharged, the air is discharged from the air discharge hole 44. The coating material discharged from the nozzle holes 48 is gradually diffused outward in the radial direction by the air diffusing action, so that the coating pattern width is expanded. The intersecting angle between the axis A of the nozzle hole 48 that extends along the direction orthogonal to the axis of the gun body 12 and discharges the coating material and the axis B of the air discharge hole 44 is 20 degrees to 40 degrees. It should be set within the range.

  In FIG. 3, the first chip 22 and the second chip 24 are threadedly engaged with a male screw part 50 formed on a disk-like outer peripheral surface and a female screw part 52 formed on the inner peripheral surface of the annular recess 18 of the gun body 12. And is detachable. A holding member 54 is interposed between the first tip 22 and the second tip 24 and the annular recess 18 of the gun body 12.

  A seal ring 56 is provided between the holding member 54 and the gun body 12, and the airtightness of the first air communication hole 46a and the second air communication hole 46b is maintained by the seal ring 56. A plurality of the air discharge holes 44 may be arranged at equal angles along the circumferential direction of the holding member 54 in plan view.

  In this case, the axis of the nozzle hole 48 of the first tip 22 is disposed so as to be substantially parallel to the axis of the gun body 12 formed in a columnar shape, and the axis direction (shaft portion 14) of the gun body 12 from the nozzle 20. The coating material is discharged along a horizontal direction substantially parallel to the axial direction of the nozzle tip 48, while the axis of the nozzle hole 48 of the second chip 24 is disposed in a direction substantially orthogonal to the axis of the gun body 12, and the nozzle The coating material is discharged from 20 in a vertically downward direction perpendicular to the axial direction of the gun body 12 (axial direction of the shaft portion 14).

  In the case where the first chip 22 and the second chip 24 are discharged simultaneously beyond the angle of the application range of the first chip 22, the coating material discharged from the first chip 22 is diffused outward in the radial direction. The expanded coating pattern and the coating pattern expanded by spreading the coating material discharged from the second chip 24 in the radially outward direction are not overlapped with each other in the nozzle hole 48 of the second chip 24. An axis line can be set. The coating pattern in which the coating material discharged from the first chip 22 is diffused and expanded, and the coating pattern in which the coating material discharged from the second chip 24 is diffused and expanded include, for example, the first chip 22 and When discharging from each of the second chips 24 at the same time, since the application surfaces (application patterns) do not overlap, the application material can be reduced and the application pattern is not uneven, which is convenient. Accordingly, the nozzle hole 48 of the second chip 24 may be disposed substantially orthogonal to the nozzle hole 48 of the first chip 22. However, when discharging from each of the first chip 22 and the second chip 24 at the same time, when it is preferable that the respective application patterns overlap, the angle of the application range of the first chip 22 is not exceeded, and the first chip 22 is not exceeded. When the two chips 24 are simultaneously ejected, the coating material ejected from the first chip 22 is diffused in the radially outward direction, and the coating pattern ejected from the second chip 24 is out of the radius. The axis of the nozzle hole 48 of the second chip 24 may be set at an angle where the coating pattern diffused and expanded in the direction overlaps.

  The coating apparatus 10 according to the embodiment of the present invention is basically configured as described above. Next, the operation, action, and effect will be described.

  Here, as a skin material, for example, a process of manufacturing an instrument panel 66 will be schematically described based on FIGS. 7A to 7E.

  First, as shown in FIG. 7A, a release agent is applied to the molding surface 70 of the molding die 68. The release agent may be either wax-based or soap-based, and it is preferable to perform wiping with a waste cloth after application in order to eliminate uneven gloss.

  After applying the release agent, as shown in FIG. 7B, an in-mold that becomes the outermost surface of the instrument panel 66 using the coating apparatus 10 according to the present embodiment attached to the distal end portion of the shaft portion 14. Apply paint (IMP) uniformly. This IMP is applied for the purpose of coloring and light resistance. Subsequently, after performing air drying as shown in FIG. 7C, as shown in FIG. 7D, using a coating device (not shown), the solidified back surface of the IMP in which the urethane resin material is uniformly applied to the molding surface 70 To be applied.

  After the application of the urethane resin material is completed, as shown in FIG. 7E, curing is promoted by heating (curing), and then the mold is removed to obtain the instrument panel 66.

  Next, the function and effect of the coating apparatus 10 according to the present embodiment will be described in detail below.

  The liquid coating material supplied via the first passage 32a and the second passage 32b of the shaft portion 14 and the rod portion 26 is transferred to the first communication passage 42a and the second communication passage 42b formed inside the gun body 12. be introduced. The coating material introduced into the first communication path 42a is supplied along the nozzle holes 48 of the first chip 22, and the first chip 22 under the action of air supplied through the first air path 34a. The nozzle 20 is discharged along a horizontal direction parallel to the axis of the gun body 12. On the other hand, the coating material introduced into the second communication path 42b is supplied along the nozzle hole 48 of the second chip 24, and the second material under the action of the air supplied through the second air path 34b. It is discharged from the nozzle 20 of the tip 24 in a vertically downward direction perpendicular to the axis of the gun body 12.

  Therefore, in the present embodiment, the coating material is simultaneously discharged from the gun body 12 in two directions orthogonal to each other and spray-coated on the molding surface 70 of the mold 68. That is, under the displacement action of a robot arm (not shown), the coating material is applied toward the straight direction of the gun body 12 via the first tip 22 and the axial direction of the gun body 12 via the second tip 24. Application materials are simultaneously applied in the orthogonal directions.

  In the conventional application gun, the discharge direction of the coating material is limited to a single direction with respect to the application site. In the present embodiment, the coating material is discharged simultaneously in a plurality of directions orthogonal to each other. (See FIG. 4).

  Therefore, in the present embodiment, the application time for the molding surface 70 of the molding die 68 can be greatly shortened and the coating operation can be performed efficiently. In the present embodiment, the application material is discharged in two directions using the first chip 22 and the second chip 24, but the discharge direction of the application material is limited to the two directions. By disposing a plurality of chips in directions orthogonal to each other, the coating material can be discharged in a plurality of directions of two or more directions. Furthermore, in this embodiment, the description is given by arranging a plurality of chips in directions orthogonal to each other. However, the present invention is not limited to this, and a plurality of chips (chip axes) are mutually connected. What is necessary is just to be arrange | positioned in the direction which cross | intersects.

  Here, FIG. 10 shows the experimental results when the coating device 10 according to the present embodiment and the vertical gun 102 according to the comparative example shown in FIG. In the experiment, the discharge amount of the coating material was set to 30 g / min, the discharge speed was set to 300 mm / sec, and the coating distance was set to 30 mm.

  In FIG. 10, a characteristic curve E indicated by a solid line shows a relationship between a displacement position and a film thickness when coating is performed simultaneously in two directions orthogonal to each other using the coating apparatus 10 according to the present embodiment. A characteristic curve F indicated by a broken line indicates a case where the characteristic curve F is applied by the vertical gun 102 according to the comparative example.

  In the vertical gun 102 according to the comparative example, the coating pattern width was 10 (mm) and the film thickness was 8 (μm), whereas in the present embodiment, the coating pattern width was 25 (mm) and the film thickness was 20 ( μm) was obtained. From such experimental results, in the present embodiment, the coating pattern width is expanded to increase the area of the coating pattern, and the coating thickness exceeds the predetermined reference value (20 μm). It was found that it was formed. As a result, in the present embodiment, the number of times of coating can be reduced as compared with the conventional one by improving the coating quality on the workpiece.

  In the present embodiment, since the gun body 12 is detachably provided from the rod portion 26 of the shaft portion 14 attached to one end portion of the robot arm (not shown) via the coupling mechanism 16, the removed gun body The first communication path 42a and the second communication path 42b through which the 12 coating materials flow can be easily cleaned. Therefore, since it can decompose | disassemble from the middle of the flow path through which an application material distribute | circulates, even if it is a case where the arbitrary locations in the said flow path are clogged, it can remove easily. As a result, in the present embodiment, even when the coating molding is continuously performed, clogging of the nozzles 20 and the like is prevented and a stable coating pattern width can be obtained.

  Furthermore, in the present embodiment, the first tip 22 and the second tip 24 having the nozzle 20 can be removed from the annular recess 18 of the gun body 12 fitted with screws and easily cleaned.

  Furthermore, in the present embodiment, the coating material is discharged only in the straight direction through the first chip 22 under the switching action of a switching mechanism (for example, a switching valve) (not shown) (see FIG. 5). The case where the coating material is discharged only in the vertically downward direction via the second chip 24 (see FIG. 6) can be appropriately selected and used.

  For example, when the coating material is applied only in the vertically downward direction via the second chip 24, the shaft portion 14 is reciprocated a plurality of times in the direction perpendicular to the paper surface of FIG. It is conceivable that the coating material is discharged only in the straight direction through the one chip 22, and the shaft portion 14 is reciprocated a plurality of times in the direction perpendicular to the paper surface of FIG. However, with such a coating method, a difference in viscosity occurs in the forward and backward paths adjacent to each other during the coating time by reciprocating a plurality of times in the direction perpendicular to the paper surface of FIG. There may be inconveniences when forming a bag-like top that closes and becomes narrower in shape.

  Therefore, in the present embodiment, the shape of the application part on the molding surface of the mold is gradually narrowed, and a plurality of chips with different application directions of the coating material from the nozzle are closed. Among them, after applying the coating material with a chip that applies only in the direction crossing the straight direction (see FIG. 6), while applying the coating material with a chip that applies only in the straight direction, or after the application, The shaft portion 14 (support portion) that supports the gun body 12 is rotated about its axis, and then the coating material is applied (see FIG. 6) with a tip that is applied only in the direction that intersects the straight direction. By selecting multiple chips and applying these chips continuously, the shape of the application part on the molding surface of the mold is gradually narrowed to form a bag-like top that closes No difference in viscosity occurs, and the shape of the application part on the molding surface of the mold can be continuously applied to a bag-like part that is gradually narrowed and closed. Such inconvenience can be eliminated. Thus, in this Embodiment, the freedom degree of the coating method can be improved further.

  Furthermore, in the present embodiment, the direction in which the coating material is discharged from the nozzles 20 to the bag-shaped portion where the shape of the coating portion on the molding surface of the mold gradually narrows and closes is mutually. By simultaneously applying the first chip 22 and the second chip 24 that are orthogonal to each other, the bag-shaped portion can be preferably applied.
