The present invention relates to a coating apparatus for coating a coating material on one surface or multiple surfaces of an extruded shape member having a two-dimensional or three-dimensional shape, and a coating method using the same.

For the sake of understanding, it is intended to define extrusion moldings and the extrusions produced thereby. Extrusion molding is a liquid resin obtained by heating a powdered polymer or thermoplastic resin at a melting point or softening point or more, and is usually pushed toward a die by using a plunger to form a shaped article, and then cooled and solidified. It is called a method of forming a product continuously by forming a product, and the article produced by this method is called an extruded shape member (押出 形 材).

Extrusions as defined above, for example, those that can be presented as a method for coating the surface of a window frame or window frame, spray coating, roll coating, dip coating, etc. Known.

Among them, spray coating is a method of coating the coating solution by spraying the high pressure to the adherend using a spray gun, which has the advantages of both single-sided coating and multi-side coating. However, in order to coat only the desired part, the uncoated part must be masked, and the spraying method takes a large amount of material to be dispersed to the periphery than the amount coated on the adherend, resulting in a large material loss and a coating agent for smooth spraying. Diluent must be added because it must have a low viscosity, there is a disadvantage in that the work maneuver is increased because the process of evaporating the diluent in the later process is required.

Roll coating is a method of coating a coating roll with a coating liquid while rolling it onto the adherend. It can be usefully used for two-dimensional flat products, but due to the nature of using a coating roll, There is a difficulty in coating a three-dimensional product having a complicated shape or irregularities due to the limitation that cannot be coated.

Dip coating is suitable for coating the entire adherend, but not for partial coating, because dip coating is a coating method for forming a coating by dipping and depositing the deposit in a solution in which the material forming the coating is dissolved or dispersed.

In addition to the coating method, there is a transfer method. The transfer method may be lifted because the adhesion of the coating layer is lowered. Therefore, a primer, which is an adhesion medium, should be used to increase the adhesive force. It is known that durability is inferior because it appears.

The transfer method is proposed in Korean Patent Application Nos. 10-1999-68110, 10-1999-68111, 10-2002-71655, and the like. Since only a method for coating a coating is proposed and a coating method for a desired site, that is, no mention of a three-dimensional coating, the coating of a product having a three-dimensional shape is impossible or possible, It is likely that there will be a lot of complexity.

Accordingly, the present invention has been made to solve the conventional problems as described above, the main object of the present invention is to provide a surface or multi-surface of the two-dimensional or three-dimensional extruded shape by a method different from the coating method described above The present invention provides a surface coating apparatus for a two-dimensional and three-dimensional extruded shape member that can be simply coated, and a coating method using the coating apparatus.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In describing the present invention, a device and a method will be described separately.

First, the coating apparatus of the two-dimensional or three-dimensional extruded shape member which is the apparatus of the present invention is included in the extruded shape member manufacturing equipment. Herein, the configuration of the first and second types of extrusion member manufacturing equipment including a coating apparatus is as follows.

However, it is assumed that the first and second types of extruded shape manufacturing equipment described herein may be changed depending on the situation.

First, the extrusion molding material manufacturing equipment of the first form comprises an extrusion device 10 for extruding a thermoplastic resin in a two-dimensional or three-dimensional shape as shown in Figure 1; Molding machine (or a calibration unit) 20 for maintaining the shape by vacuum suction of the surface of the extruded extruded shape that is not completely cured in order to prevent deformation of the extruded extruded shape; A coating device 30 for coating a coating on a desired portion of the extruded shape member; A curing device 40 for curing the coating agent; A drawing device (50) for drawing out the coated extruded shape member to the outside; A cutting device 60 for cutting the extracted extruding member to an appropriate size; Stacker 70 for classifying and loading the cut extruded shape member.

Next, the extrusion apparatus for manufacturing a second form of extrusion equipment as shown in Figure 2 and the injection device 80 for inserting the curable extrusion member in a state cut to the appropriate length by extrusion molding in a two-dimensional or three-dimensional shape; A washing apparatus 90 for washing the injected extruded shape member; A coating device 30 for coating a coating on a desired portion of the extruded shape member; A curing device 40 for curing the coating agent; A transfer device 100 for transferring the extruded shape member; Stacker 70 for sorting and loading the extruded shape.

Here, four embodiments of the common coating apparatus 30 included in each of the above manufacturing facilities are presented.

The coating apparatus of the first embodiment is elastically flowable in the vertical direction by the fixing rail 310 and the elastic member 302 on the fixed rail 310 is installed on the base 301 as shown in Figures 3 to 7 Rail unit 300 made of a variable rail 320 to serve to isolate the coating surface (1a) and the uncoated surface (1b) while supporting the extruded shape member 1 of the two-dimensional or three-dimensional shape is installed Have Here, the extruded shape member 1 may be a cover body (not shown), which is a three-dimensional shape such as a window frame or a window frame, or a two-dimensional shape fitted to one surface of the window frame.

The rail unit exerts a force to be in close contact with the extrusion member 1 due to the elastic force of the elastic member 302 installed between the base 301, so that a gap does not occur between the rail unit and the extrusion member (g). Thus, the coating surface 1a and the uncoated surface 1b are isolated (more specifically, sealed). The reason for isolating the coated surface and the uncoated surface is to prevent the coating agent from entering the uncoated surface. In addition, the upper end of the introduction side (in) of the rail unit 300 is gently inclined so that the extruded shape member 1 can be smoothly introduced without being caught when first entering the rail unit.

And, it has a coating unit 330 for randomly applying a predetermined amount of coating liquid to a specific surface (top surface) of the extruded shape member. At this time, the coating unit is a coating liquid injection nozzle 331 installed on the upper surface of the extruded shape member (1), the coating liquid storage tank 332 in which the coating liquid is stored, and the coating liquid of the coating liquid storage tank to the coating liquid injection nozzle through the tube. It is composed of a pulsation-free metering pump 333 to supply.

The pulsation-free quantitative pump 333 serves to pump the coating liquid so that a certain amount of the coating liquid can be ejected without pulsation. Pulsating pump is theoretically possible because the coating liquid is sprayed periodically and the coating thickness can be irregular, but it is desirable to be excluded in practice.

The coating liquid injection nozzle 331 is installed on the support 303 installed on the base 301 to move the left and right positions and to adjust the vertical angle, it is possible to adjust the position and angle according to the extruded shape. .

In addition, by spraying the coating liquid (c) applied on the extruded shape member 1 with uniform pressure, the coating liquid is diffused so that the coating liquid is coated with a constant thickness.

Here, the air knife is the upper air knife 341 for injecting air to the upper surface of the extruded shape member 1, and the first side air knife 342 for injecting air to one side of the extruded shape member (1) It is composed of a second side air knife 343 for injecting air to the other side of the extruded shape member (1). The upper air knife 341, the first side air knife 342, and the second side air knife 343 are provided to be supported by the support 304 to adjust the position and the angle thereof.

The air knife 340 blows air in a laminar form for uniform surface coating of the extruded shape member 1. At this time, the laminar air supplies unit pressure and a certain amount of air to the desired area for coating, and the pressure and amount take into consideration the thickness of the part to be coated and the degree of coating texture to be expressed or the characteristics of the extruded shape and the process temperature. Is determined.

Hereinafter, the operation of the first embodiment will be described.

As shown in Figures 4a and 4b, when the extrusion molded member 1 extruded into a two-dimensional or three-dimensional shape is transferred to the coating apparatus, the extrusion member is assembled with the rail unit 300 manufactured according to the shape of the extruded member. Guided along. At this time, the upper end of the rail unit is introduced smoothly because there is a gentle inclined surface 321 is introduced when the extruded shape member is introduced. The extruded shape member 1 transported along the rail unit 300 is coated with a coating liquid on its surface by a coating liquid injection nozzle 331 installed on the introduction of the rail unit as shown in FIGS. 5A and 5B. That is, the coating liquid stored in the coating liquid storage tank 332 is discharged to the coating liquid injection nozzle 331 by the pumping force of the pulsation-free pulsation metering pump 333. Will be buried.

The coating liquid (c) buried in this way is uniformly spread on the upper surface of the extruded shape member (1) by the constant air pressure discharged from the air knife (340) installed at an oblique angle at the rear of the rail unit (300) and coated at a constant thickness. do. If the surface of the extruded member to be coated is the upper side and both sides (3D), the coating agent pushed out by the air pressure of the air knife flows down to both sides of the extruded member, and the flowing coating agent is the first side air knife as shown in FIG. 342 and the second side air knife 343 are uniformly coated on both sides of the extruded shape by the constant air pressure discharged, the remaining coating liquid coated and the collection hopper 305 installed under the base 301 Through the coating liquid storage tank 332 is introduced through. On the other hand, if the surface to be coated of the extruded shape member 1 is limited to the upper surface (two-dimensional), it is not necessary to use the first and second side air knife, so the direction may be turned to another place.

In the coating liquid coating process, the variable rail 320 is in close contact with the bottom surface of the extruded shape member 1 by the upward elastic force of the elastic member 302 as shown in FIG. By blocking the bottom of the uncoated surface of the coating agent can be prevented from transition from the coating surface to the uncoated surface.

The coating apparatus of the second embodiment differs only in the configuration of the rail unit from the first embodiment, and the coating unit and the air knife have the same configuration. Therefore, description of the rest of the components except the rail unit will be omitted in order to avoid redundant description.

As shown in FIG. 8, the rail unit 300a of the second embodiment has a one body unlike the first embodiment divided into two, and the elastic member 302 is formed of the rail unit 300a and the base 301. ) Is installed between the entire rail unit has a configuration capable of elastic flow.

The coating apparatus of the third embodiment has the same configuration as that of the coating unit and the air knife, except that only the rail unit is different from the first embodiment. Therefore, in order to avoid overlapping description, the description of the rest of the components except for the rail unit will be omitted.

As shown in FIG. 9, the rail unit 300b of the third embodiment is provided with an elastic body 302b for blocking the coating surface 1a and the uncoated surface 1b at a portion where the extruded shape member 1 is supported. Herein, the elastic body 302b means urethane in detail, but is not limited thereto, and any elastic body having flexibility and elasticity may be applied. However, it should be noted that it is preferable to apply an elastic body having a certain degree of durability in consideration of the fact that the elastic body causes continuous friction with the extruded shape member.

The coating apparatus of the fourth embodiment is different from the above-described first embodiment in that the configuration of the rail unit is different and that the air supply means is provided. Let's do it.

In the rail unit 300c of the fourth embodiment, as shown in FIGS. 10A and 10B, an air nozzle 301c facing the boundary between the coated surface 1a and the uncoated surface 1b of the extruded shape member 1 is formed. Air supply means 310c for supplying air to the air nozzle is provided. As the air supply means, a ring blower or a compressor is used.

Here, the size and the number of holes of the air nozzle are determined in consideration of the pressure or volume of the laminar air. If the pressure of the laminar air is high, the nozzle hole is made larger, and when the fine surface treatment is required, the hole of the air nozzle is increased. It can be small. The speed or pressure of the air passing through the air nozzle 301c may be adjusted through an external device, or may be adjusted using a venturi tube shape or the like.

The air nozzle 301c blocks the inflow of the coating agent by spraying air in the opposite direction to which the coating agent flows in order to prevent the coating liquid flowing down from the coating surface 1a from flowing into the uncoated surface 1b. Do it.

Next, the coating method of the two-dimensional or three-dimensional extruded shape member of the present invention will be described.

The coating method of the extruded shape member according to the present invention, as shown in Figure 11 the step of extruding the thermoplastic resin in a two-dimensional or three-dimensional shape in the molten state (S1); A shaping step (S2) of vacuum sucking the surface of the extruded extruded material that is not completely cured for maintaining the shape of the extruded extruded shape; Coating (S3) a desired surface (cross section or surface) of the extruded shape member 1; Curing the coated coating liquid of the extruded shape member (S4); Drawing out the coated extruded shape member (S5); Cutting the extruded extruded shape member to an appropriate size (S6); From the extruded member manufacturing method consisting of the step (S7) to classify loading the cut extruded member,

The coating method (S3), the step (S30) of randomly applying a predetermined amount of the coating agent (c) on a specific surface of the extruded shape, and the coating surface (1a) and the uncoated surface (1b) of the extruded shape Dispersing the coating liquid on the surface of the extruded shape by spraying air at a uniform pressure to the coating liquid applied on the extruded shape (laminar flow air blow) in an isolated state so that the coating liquid is coated with a constant thickness on the surface of the extruded shape. (S31) or

Or, randomly applying a predetermined amount of the coating agent (c) on a specific surface of the extrusion (1) (S30); By spraying the coating liquid applied on the extruded material with equal pressure (laminar flow air blow), the coating liquid is diffused so that the coating liquid is coated to a predetermined thickness on the surface of the extruded material, but from the uncoated surface 1b of the extruded material. And spraying air toward the coating surface 1a to block the coating liquid from entering the uncoated surface (S32).

The coating thickness formed on the surface of the extruded shape through the laminar air blow and the latter air blow process of the former and the latter depends on the flux of the extrudate, the viscosity of the paint, the pressure and volume of air per unit area, and the distance between the extruded shape and the air nozzle. Can vary. Therefore, the thickness of the coating to be made on the surface of the extruded shape can be adjusted using the correlation of the parameters listed above.

On the other hand, the curing step is different depending on whether the coating is a thermosetting or ultraviolet curing type, if the coating is an ultraviolet coating, the curing by an ultraviolet lamp (not shown) installed in the curing device 40, heat In the case of using a curable coating agent, the curing is performed by a heating element such as a heating wire (not shown).

As described above, the present invention provides an advantage that a single surface or a multi surface of an extruded shape member having a two-dimensional or three-dimensional shape can be simply and without defects coated.

The coating process has an advantage of maintaining the airtightness between the rail and the extruded shape member so that the coating liquid does not flow into the unwanted portion of the coating process has the advantage of improving the completeness of the coating operation.
