Decorated-part having a fine decoration using a laser processed groove
A method for manufacturing a decorated-part comprises a first and second base coat-layer-forming process, a surface coat-layer-forming process and a laser-decorating process. In the first base coat-layer-forming process, the first base coat-layer colored in a highly light color at a lightness-level of 70 or more is formed on the surface of the resin base-material 12. In the second base coat-layer-forming process, the second base coat-layer 21C colored in a chromatic color is formed on the first base coat-layer. In the surface coat-layer-forming process, the surface coat-layer colored in a less-bright color at a lightness-level of 20 or less is formed on the second base coat-layer 21C. In the laser-decorating process, the first laser-processed groove penetrating the surface coat-layer and exposing partially the second base coat-layer is made by irradiating the infrared laser onto such surface coat-layer, thus providing a fine decoration onto the surface of said decorated-part.

The blowing nozzle 50 has a blowing port 51 formed in the ceiling of the coating chamber 20, and a cover 52 for covering the blowing port 51 from the coating chamber 20 side. The cover 52 comprises a facing wall 53 disposed facing the blowing port 51, and an erected wall 54 erected from an outer edge part of the facing wall 53 and abutted against an opening edge of the blowing port 51. The facing wall 53 and the erected wall 54 are both formed from punching metal or a slit plate, and the opening ratio of the punching metal or slit plate constituting the facing wall 53 is greater than the opening ratio of the punching metal or slit plate constituting the erected wall 54.
This invention provides a method for manufacturing decorated-parts of high design-quality and reliability, since the exposed surface of the base coat-layer is not bulged, and thus the color of said coat-layer is distinct. The method for manufacturing decorated-parts of this invention comprises a base coat-layer-forming process, a surface coat-layer-forming process and a laser-decorating process. In the base coat-layer-forming process, a resin-base material of a highly light color at a lightness-level of 70 or more or a clear and colorless resin base-material is formed. In the surface coat-layer forming process, the surface coat-layer of a less-bright color at a lightness-level of 20 or less is formed on the base coat-layer. In the laser-decorating process, the first laser-processed groove penetrating the surface coat-layer and exposing partially the base coat-layer is made by irradiating the infrared laser onto such surface coat-layer, thus providing a fine decoration onto the surface of said decorated-part.

This invention provides a method for manufacturing a decorative-part of which the joint-lines bordering the laser-irradiation regions are unnoticeable, thus avoiding deterioration of the design-quality of such a decorative-part.

[Problem] To provide a coating booth wherein a flow rate for air smaller than the conventional can be made to flow downward in a coating processing area where coating of a workpiece is carried out. [Solution] This coating booth 10 is configured such that band-shaped areas extending along a pair of mutually opposing outside edge parts of the ceiling part of the coating booth form a pair of air delivery units 36, 36 for delivering air downward, and an area between the pair of band-shaped areas forms a normal ceiling part 34 where air is not delivered. When air is delivered downward by the pair of air delivery units 36, 36, the air vertically below the normal ceiling part 34 is affected by that air and flows downward extremely slowly. A coating processing area R1, where workpiece W coating is carried out, is disposed vertically below the normal ceiling part 34. Thus, the flow rate of downward flowing air in the coating processing area R1 can be made smaller than the conventional.

The purpose of the present invention is to provide a decorative component which can enhance design properties as a result of drawing a design, having a stereoscopic view effect, on a decoration surface of a component material.

A method for decorating a given part is designed to print designs onto a coat layer deteriorating the coat layer on the surface of the given part. In the coat layer-forming process, in spreading the metallic-coating material containing aluminum flake onto the surface of the resin compact, the coat layer is formed on the surface of it. In a laser-printing process, a laser is irradiated on the condition of being able to maintain the same state of the coat layer before and after irradiating the laser, so as to reduce the aspect ratio of the micronized-metallic powder, which is the average value of the ratio of the maximum dimension of the micronized-metallic powder to the average value of the minimum dimension of the micronized-metallic powder, which laser irradiation eventually thermally deforms the first scale-shaped micronized-metallic powder into a spherical shape in the coat layer to print designs on the film.

The clear coating layer (4) is formed by spraying a clear coating composition over the surface of the decorative layer (2) with an atomization-type coater, the clear coating composition containing an ester-based solvent that is a low-boiling-point solvent having a boiling point below 100°C, as the main solvent, and having a solid content of 35-40 mass%. Thus, the clear coating layer has a surface partly reduced in gloss, and a decorative component having a highly attractive appearance is produced.
The objective of the present invention is to provide a method for manufacturing a decorative part for which the joints between adjacent laser irradiation regions are not very noticeable, thus avoiding a degradation in the design characteristics of the decorative part. Therefore, a design (4) is formed by closely arranging multiple first blocks (6), comprising multiple design patterns (5), and multiple second blocks (8), comprising multiple design patterns (7) which differ from the design patterns (5) forming the first blocks (6). In a laser irradiation region setting step, a region to be decorated is divided into multiple laser irradiation regions (LR1-LR3). At that time the joints (J1-J2) between the multiple laser irradiation regions (LR1-LR3) are set along the boundary between the first blocks (6) and the second blocks (8) in the design (4). In a laser irradiation step, a laser deflection unit is moved in a relative manner and each of the multiple laser irradiation regions (LR1-LR3) are irradiated by the laser.
An electrostatic coating apparatus includes: a spray gun configured to spray a coating material onto a coating object; a voltage application device configured to apply a high voltage to the spray gun; and a current measurement device configured to measure electric current flowing through the spray gun. When the spray gun, which is in a state of not spraying the coating material onto the coating object and is under application of the high voltage from the voltage application device, is located at a distance from the coating object, the electric current flowing through the spray gun is measured by the current measurement device. A grounded state of the coating object is checked, based on the measured electric current. This shortens the time required for checking the grounded state, while allowing for downsizing and simplified configuration of production equipment and reduction of equipment cost.

Provided is a decorating device for vehicle interior components which can accurately impart gradation to a design on the surface of a resin molded article. The decorating device is equipped with a laser irradiation device and a control device. The control device estimates a virtual decoration surface (5a) which is deformed so as to have a different curvature than the surface shape of an actual decoration surface (5), and prepares drawing data on the virtual decoration surface (5a). The control device prepares laser irradiation data on the basis of the drawing data and controls the laser irradiation device by means of the laser irradiation data. By emitting a laser beam (L1) so as to be focused on the virtual decoration surface (5a), the laser irradiation device performs laser machining of the actual decoration surface (5) with the focal point of the laser beam (L1) offset from the decoration surface (5) and thus forms a gradation.

In a coating formation step, a coating (3) is formed on the surface of a molded resin body by coating with a metallic paint that includes aluminum flakes (7a). In a laser drawing step, a laser (L1) is fired under laser firing conditions wherein the surface state of the coating (3) can be maintained in the same state before and after laser firing. By firing the laser (L1) on the coating (3), aluminum flakes (7a) in the coating (3) are thermally deformed from flakes to spheres, forming a pattern (4), such that the aspect ratio for those aluminum flakes (7a), which is denoted by the ratio of the average value of the maximum dimensional part to the average value of the minimum dimensional part, is reduced.

A painting material charging device may comprise a cartridge attaching unit, a painting material supplying path, a first switching unit, a painting material supplying unit, a discharging path, a second switching unit, a painting material sensor and a controlling unit. The controlling unit may be configured to be connected to the painting material sensor and the second switching unit. The controlling unit may be configured to cause the second switching unit to fully close the discharging path in a case where the painting material sensor detects the painting material.
According to the present invention, even though the paint is filled or discharged repetitively to or from the paint bag (5), so that bursting of a coating bag (5) or lack of coating material during coating are not caused by accumulation of error between the filling amount and the using amount.
That is, before a predetermined amount of the coating material is supplied to the coating material bag (5), the remaining coating material in the coating material bag (5) is extruded to empty it, since the coating material bag (5) is squashed by the pressure of fluid which was supplied to the hydraulic fluid chamber (6) outside of the bag.
For providing a coating material cartridge capable of reliably discharging air and coating material stagnated in a hydraulic fluid chamber, a coating material cartridge has a cartridge main body, a partition body, a coating material transfer path and a plurality of hydraulic fluid transfer paths. The cartridge main body is detachably attached to a coating material filling device. The partition body partitions the inner region of the cartridge main body into a coating material chamber and a hydraulic fluid chamber. The coating material transfer path communicates the coating material chamber and the outer region of the cartridge main body, and each of the hydraulic fluid transfer paths communicates the hydraulic fluid chamber and a outer region of the cartridge main body. Each of the hydraulic fluid transfer paths has a plurality of openings that opens in the hydraulic fluid chamber and the distance for each of the openings from the connection end face is different from each other.
The amount of a coating material discharged to the outside of a coating material supply route in an air bleeding process is reduced. A coating material charging device (10) has a cartridge installation section (12), the coating material supply route (70), a trigger valve (72), a coating material supply device (20), a discharge route (76), a selection device (48), a coating material sensor (42), and a controller (80). The coating material supply route (70) communicates with a coating material cartridge (1) installed on the cartridge installation section (12). The coating material supply device (20) sends the coating material to the coating material supply path (70). The trigger valve (72) changes between communication and disconnection between the coating material supply route (70) and the coating material cartridge (1). The discharge route (76) communicates with the coating material supply route (70). The coating material sensor (42) detects the coating material in the discharge route (76). The controller (80) is connected to the coating material sensor (42) and the selection device (48). When the coating material sensor (42) detects the coating material, the controller (80) causes the selection device (48) to totally close the discharge route.

A hopper for cleaning a coating machine in which a rotary atomizing head extends through an opening in the upper surface of a hopper housing, a thinner for cleaning the rotary atomizing coating machine and a residual coating material are sprayed on the inside, an airstream control member for preventing flow from ascending from the inside of the housing to the outside of the housing through a gap between the coating machine and the opening by the rotation of the rotary atomizing head corresponding to the gap between the coating machine and the opening, and the control member is formed with an air vent hole for supplying air to a negative pressure zone formed just below the rotary atomizing head.
A method of cleaning coating material remaining in a coating material path for supplying coating material to a rotary atomizer head, the cleaning being performed by alternately supplying cleaning air and cleaning liquid, in that order or in the reverse order, to the coating material path. When pigments contained in coating material to be cleaned has high hardness, the cleaning liquid supply time period in which the cleaning liquid is first supplied to the coating material path is set longer (pattern B) than a standard time period (pattern A) or alternately the pressure of cleaning air first supplied to the coating material path is set lower than a standard pressure (pattern C). The pattern B reduces the amount of coating material remaining in the coating material path, and the pattern C reduces the speed of coating material colliding with a center cone. Thus, the patterns B and C reduce abrasion of the center cone with their respective ways.
2 can be reduced by reducing the total jetted amount of paint to enable the atomization of the paint at low rotating speeds so as the increase the deposit efficiency.
