Technical Field

The present disclosure relates to a coating apparatus and a method of setting the coating apparatus.

Background

A coating booth in which a coating work area is formed is known (see, for example, japanese patent laid-open No. 2-6868). In the coating booth, a tunnel-shaped coating work area is formed by the ceiling portion, both side walls, and the bottom plate. A conveyor is provided on the base plate, and the conveyor is configured to convey the object to be coated. An automatic coating machine is arranged in the coating operation area. The automatic coating machine is configured to coat a conveyed coating object.

The automatic coating machine is provided in the housing. The automatic coating machine and the box body form a coating machine unit. The coating machine unit is assembled at the side part of the coating room.

Here, the coater unit is separately assembled in advance in a factory, and is assembled to the coating booth after being carried to the site where the coating booth is constructed. That is, the automatic coating machine is arranged in the coating operation area of the coating booth by the case being assembled to the coating booth. Thus, the operation of assembling the automatic coating machine itself to the coating booth is not required to be performed at the site where the coating booth is constructed. This makes it possible to shorten the time required for installation work at the construction site of the coating booth.

In the coating booth as described above, the time required for installation work at the construction site of the coating booth can be shortened. However, in order to change the size of the painting work area, the framework of the entire painting booth needs to be changed. This makes it difficult to change the size of the coating work area.

Detailed Description

Hereinafter, an embodiment of the present disclosure will be described.

First, a schematic configuration of a coating apparatus 100 according to an embodiment of the present disclosure will be described with reference to fig. 1 and 2.

The coating apparatus 100 is a device for coating an object 150 to be coated. As shown in fig. 1, the coating apparatus 100 includes side units 1 and 2, an air supply unit 3, and an air exhaust unit 4. The coating device 100 includes a coating region 5 for coating. In fig. 1 and the like, the X direction is the width direction of the coating apparatus 100, the Y direction is the longitudinal direction of the coating apparatus 100 (the conveying direction of the object 150 to be coated), and the Z direction is the height direction of the coating apparatus 100 (the vertical direction). Therefore, fig. 1 is a schematic view when viewed in a cross section orthogonal to the conveyance direction (moving path direction) of the object 150 to be coated.

The side units 1 and 2 are disposed so as to face each other across the coating region 5 and above the exhaust unit 4. The side unit 1 is provided with a coating robot 11. The side unit 2 is provided with a coating robot 21. The coating robots 11 and 21 are configured to coat the object 150 to be coated in the coating area 5. The object 150 is, for example, a vehicle body.

The air supply unit 3 is disposed above the painting area 5 and is configured to supply air to the painting area 5. The air supply unit 3 is provided between the side units 1 and 2 and is disposed above the side units 1 and 2. The exhaust unit 4 is disposed below the painting area 5 and is configured to exhaust air of the painting area 5. The exhaust unit 4 is provided with a conveyor 6. The conveying device 6 is configured to convey the object 150 in a conveying direction (Y direction).

When the coating apparatus 100 coats the object 150, a flow of air (down flow) from the air supply unit 3 to the air exhaust unit 4 is formed in the coating region 5. Thereby, the paint particles (overspray) that are not applied to the object 150 can be discharged from the painting area 5.

Specifically, as shown in fig. 2, the side unit 1 constitutes one side surface of the coating apparatus 100. The side unit 1 includes two painting robots 11, an auxiliary robot 12, and a control panel 13. The coating robot 11 and the auxiliary robot 12 are disposed in the coating area 5. The control panel 13 is disposed outside the coating region 5.

The two coating robots 11 are arranged in the conveying direction. One coating robot 11 is disposed above the other coating robot 11. One (upper) coating robot 11 is disposed inside the other (lower) coating robot 11 in the width direction. Each painting robot 11 includes a spray gun 111 for atomizing paint and a robot arm 112 for moving the spray gun 111. The base of the robot arm 112 is mounted to a support 113. The details of the lance 111 will be described later. The control panel 13 is configured to control the coating robot 11.

The side unit 2 constitutes the other side surface of the coating apparatus 100. The side unit 2 includes two painting robots 21, an auxiliary robot 22, and a control panel 23. The two coating robots 21 and the auxiliary robot 22 are disposed in the coating area 5. The control panel 23 is disposed outside the coating region 5.

The two coating robots 21 are disposed so as to face the two coating robots 11 in the width direction (X direction). The two coating robots 21 are arranged in the conveying direction. One coating robot 21 is disposed above the other coating robot 21. One (upper) coating robot 21 is disposed inside the other (lower) coating robot 21 in the width direction. Each painting robot 21 includes a spray gun 211 for atomizing paint and a robot arm 212 for moving the spray gun 211. The base of the robot arm 212 is fitted to the support column 213. Note that the spray gun 211 is configured to be the same as the spray gun 111. The control panel 23 is configured to control the coating robot 21.

The air supply unit 3 is disposed above the coating area 5, and constitutes a ceiling (upper surface) in the coating area 5. The air supply unit 3 has an air supply chamber 31 in a rectangular box shape. A duct connecting portion 32 is provided on the upper surface of the air supply chamber 31. The air supply duct 7 is connected to the duct connection portion 32. An inlet 33 for introducing air into the coating region 5 is provided on the lower surface of the air supply chamber 31. A filter 34 for removing dust and the like in the air is attached to the inlet 33.

The temperature and humidity-adjusted air from the air conditioner (not shown) flows into the air supply chamber 31 through the air supply duct 7. The air supply chamber 31 has a function of rectifying air flowing in from the air supply duct 7. Air supply chamber 31 is provided with an air volume adjusting damper 35 in the internal space. Air volume adjusting damper 35 partitions the internal space of air supply chamber 31 into upstream side space 311 and downstream side space 312. The upstream space 311 communicates with the air supply duct 7. The downstream space 312 communicates with the coating region 5 through the filter 34 of the introduction port 33. The air volume adjusting damper 35 is provided to adjust the volume of air per unit time flowing from the upstream side space 311 to the downstream side space 312.

The exhaust unit 4 is disposed below the coating region 5. The conveyance device 6 is provided at the center of the exhaust unit 4 in the width direction (X direction). The exhaust unit 4 includes a grid plate 41 constituting a bottom plate (lower surface) in the coating region 5, and an exhaust chamber 42 disposed below the grid plate 41.

The exhaust chamber 42 is provided with a plurality of exhaust ports 421. A filter 422 is attached to each discharge port 421. The filter 422 is a thin dry filter and is provided to remove paint particles in the air. Therefore, when air from the painting area 5 is taken into the exhaust chamber 42 through the exhaust port 421, paint particles in the air are removed by the filter 422. Further, an exhaust duct 8 is connected to the exhaust chamber 42. The exhaust chamber 42 communicates with the outside via an exhaust duct 8.

The conveyor 6 is provided to carry the object 150 into the coating area 5 and carry the object 150 out of the coating area 5.

[ spray gun ]

Next, referring to fig. 9 to 11, the spray gun 111 of the coating robot 11 will be described.

As shown in fig. 11, the lance 111 is configured to: the linear paint P1 is discharged from the spin head 51, and the linear paint P1 is electrostatically atomized to form paint particles (atomized paint) P2, and the paint particles P2 are applied to the object 150.

As shown in fig. 9, the spray gun 111 includes: a rotary head 51, an air motor (not shown), a cap (cap)52, a paint supply pipe 53, and a voltage generator 54 (see fig. 11). The pneumatic motor rotates the rotary head 51. The cap 52 covers the outer circumferential surface of the spin head 51. The paint is supplied to the spin head 51 through the paint supply pipe 53. The voltage generator 54 applies a negative high voltage to the spin head 51.

The spin head 51 is configured to be supplied with paint of liquid and discharge the paint by centrifugal force. In the spin head 51, a paint space S is formed by fitting the hub (hub) 511. The tip of the paint supply pipe 53 is disposed in the paint space S. The paint stored in the paint cartridge is supplied to the paint space S through the paint supply pipe 53. A plurality of outflow holes 511a for allowing paint to flow out of the paint space S are formed in the outer edge portion of the hub 511.

A diffusion surface 51a for diffusing the paint by a centrifugal force is formed on the outer side of the spin head 51 in the radial direction with respect to the outflow hole 511 a. The diffusing surface 51a is formed to have a diameter that increases toward the distal end side of the spin head 51, and is arranged to form the paint flowing out of the outflow hole 511a into a film shape. As shown in fig. 10, a groove 51c for discharging the film-like coating material in a linear shape is formed in the outer edge 51b of the diffusing surface 51 a. In fig. 9, the groove 51c is not shown in view of visibility.

The groove portion 51c is formed to extend in the radial direction when viewed from the axial direction, and is provided in plurality in the circumferential direction. That is, the groove 51c is formed in the outer edge 51b of the diffusing surface 51a so as to extend in the direction in which the diffusing surface 51a is inclined. The groove 51c is formed to reach the outer end of the rotary head 51 in the radial direction. Therefore, the distal end of the rotary head 51 has an uneven shape when viewed from the outer peripheral surface side.

As shown in fig. 11, a negative high voltage is applied to the spin head 51 by the voltage generator 54, and the linear paint P1 discharged from the groove portion 51c of the spin head 51 of the spray gun 111 is charged. The linear paint P1 is split into paint particles P2 by repulsive force generated by the charged charges. That is, the linear paint P1 discharged from the groove 51c of the spin head 51 is electrostatically atomized to become paint particles P2. That is, the coating robot 11 is not provided with an air discharge portion configured to discharge the shaping air. Thus, paint particles P2 were formed without the aid of forming air. Therefore, the coating robot 11 is an electrostatic atomization system without the molding air, and does not generate the flying of the paint particles by the molding air. Therefore, the generation of the excessive spray is suppressed, and the generation range of the excessive spray is narrowed.

In the coating apparatus 100 (see fig. 2) provided with the electrostatic atomization type coating robots 11 and 21, the energy consumption and CO can be reduced by reducing the size of the coating apparatus 100₂The discharge amount is reduced. For example, the dimensions of the coating apparatus 100 shown in fig. 2 are such that the width (length in the X direction) is 9m, the height (length in the Z direction) is 5.6m, and the length (length in the Y direction) is 4.5 m.

That is, the three exhaust modules 40a to 40c are stacked in two layers, two of the three exhaust modules are disposed in the lower layer, and the remaining exhaust module is disposed in the upper layer.

Therefore, the coating apparatus 100 is transported by six trucks.

Next, each module transported to a predetermined installation location is mounted, and the coating apparatus 100 is installed at the predetermined installation location.

Specifically, as shown in fig. 8, the exhaust modules 40a to 40c are arranged such that the short dimension direction thereof is oriented in the conveyance direction (Y direction) of the object 150 (see fig. 2) and are arranged adjacent to each other in the conveyance direction (Y direction).

As shown in fig. 7, the air supply modules 30a to 30c are arranged such that the short dimension direction is oriented in the conveyance direction (Y direction) of the object 150 to be coated, and are adjacent to each other in the conveyance direction (Y direction). Also, the adjacently disposed air supply modules 30a and 30b are coupled, and the adjacently disposed air supply modules 30a and 30c are coupled. Therefore, the air supply unit 3 is installed at a predetermined installation location. That is, the air supply chamber 31 is formed by connecting the air supply chamber constituent bodies 31a to 31c (see fig. 2). At this time, an air flow rate adjusting damper 35 (see fig. 2) is formed inside the air supply chamber 31, and a filter 34 (see fig. 2) is formed on the lower surface of the air supply chamber 31.

And, an air supply unit 3 is assembled at the upper end portions of the side units 1 and 2. In this way, the coating apparatus 100 having the coating region 5 is installed at a predetermined installation location.

The coating region 5 may be constituted by, for example, the lower surface of the air supply chamber 31, the partition walls 16a to 16c of the side cell 1, the partition walls 26a to 26c of the side cell 2, the lattice plates 17a to 17c of the side cell 1, the lattice plates 27a to 27c of the side cell 2, and the lattice plate 41 of the exhaust cell 4. Since the coating robots 11 and 21 and the auxiliary robots 12 and 22 are not provided, the width (length in the X direction) between the side blocks 10b and 20b in the coating area 5 and the width between the side blocks 10c and 20c in the coating area 5 are set to be narrower than the width between the side blocks 10a and 20a in the coating area 5. The air discharged downward from the coating area 5 through the grid plates 17a to 17c, 27a to 27c, and 41 is taken into the exhaust chamber 42 through the partition walls 44a to 44c and does not escape to the outside.

However, since the frames 14a to 14c are shared, the side module 10a can be easily assembled with the side modules 10b and 10 c. The same applies to the side unit 2.

Further, in the present embodiment, the width between the side modules 10b and 20b in the painting area 5 and the width between the side modules 10c and 20c in the painting area 5 are narrowed. This can reduce the coating region 5. Thereby, energy consumption and CO can be reduced₂And discharging the amount.
