Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of the features described in the embodiments are essential for the invention. Two or more of the plurality of features described in the embodiments may be arbitrarily combined. Also, the same or similar configurations are assigned the same reference numerals, and duplicate descriptions are omitted.

[0010] <First Embodiment> <Configuration of Coating System> FIG. 1 is a schematic diagram showing a part of the configuration of a coating system 1 to which the coating apparatus of the present invention is applicable. In each figure, arrows X and Y indicate horizontal directions orthogonal to each other, and arrow Z indicates the vertical direction (the height direction of the coating apparatus).

[0011] The coating system 1 is a decoration system that decorates the adherend W by coating the film F on the adherend W. The coating system 1 includes a control device 2, a transport device 3, and a coating device 4.

[0012] The control device 2 is an electronic circuit that controls the entire coating system 1. The control device 2 includes, for example, a processing unit, a storage unit, an input / output interface (I / O), a display unit, and an input unit. The processing unit is a processor represented by a CPU, and executes a program stored in the storage unit to control the coating system 1. The storage unit is a storage device such as a ROM, a RAM, or an HDD, and stores various control information in addition to the program executed by the processing unit. The input / output interface is an interface that transmits and receives signals between the processing unit and external devices (actuators such as motors and sensors). The display unit is a display that displays information to the user. The input unit is a key switch for the user to input instructions. The display unit and the input unit may be configured by a touch panel.

[0013] The conveying device 3 conveys the adherend W into and out of the coating device 4. The arrows in the figure indicate the conveying direction of the adherend W. In the case of this embodiment, the conveying device 3 is a roller conveyor provided with a plurality of rollers. The adherend W is held by a jig G placed on a conveying platform T such as a pallet, and is conveyed into the coating device 4 from the upstream conveying path 3a by the conveying device 3. Then, after the film is coated inside the chamber of the coating device 4, the adherend W is conveyed out from the downstream conveying path 3b. Note that the conveying device 3 may further include, for example, a conveying position adjustment unit that adjusts the conveying position of the conveying platform T. Also, the conveying device 3 may be various conveyors such as a belt conveyor other than a roller conveyor, or may be an articulated robot.

[0014] The coating device 4 is a device that coats the film F on the adherend W. As an example, the coating device 4 is a vacuum forming device that improves the adhesion of the film F to the adherend W by utilizing the air pressure difference. Details of the coating device 4 will be described later.

[0015] In this embodiment, the adherend W will be described as a member such as the front bumper or rear bumper of a vehicle (for example, a four-wheeled vehicle), but the adherend W is not limited to these, and the present invention can be applied to various objects.

[0016] In this embodiment, the film F is, for example, a film F made of a material having stretchability, specifically a thermoplastic resin. For example, its surface layer has a decorative layer with a color or pattern for decorating the adherend W, and the lowermost layer has an adhesive layer and has a multilayer structure. By coating such a film F on the adherend W, for example, the members of the vehicle can be decorated according to the vehicle color.

[0017] The coating system 1 is not limited to the above-described configuration, and may include, for example, a robot device for exchanging the adherend W and the jig G, a dust removal device for removing contaminants from the adherend W, and the like. Further, the coating system 1 may include a light irradiation unit that irradiates light such as ultraviolet rays onto the adherend W and the film F, a drying unit that dries the adherend W and the film F, and the like. Further, the coating system 1 may include a trimming unit that partially removes the unnecessary film F after the adherend W is coated with the film F.

[0018] <Coating device> Next, the details of the coating device 4 will be described. As shown in FIG. 1, the coating device 4 includes a film supply unit 5, a film transfer unit 6, a chamber 7, and a pressure adjustment unit 8. The coating device 4 moves the film F supplied from the film supply unit 5 into the chamber 7 by the film transfer unit 6. The dotted line portion of the chamber 7 shown in FIG. 1 represents the inside of the chamber 7. The coating device 4 coats the adherend W with the film F inside the chamber 7. During the coating operation, the pressure adjustment unit 8 adjusts the pressure inside the chamber 7.

[0019] Hereinafter, each component included in the coating device 4 will be described with reference to FIGS. 2 and 3 in addition to FIG. 1. FIGS. 2 and 3 are diagrams showing the internal configuration of the coating device 4. FIG. 2 is a view of the coating device 4 as seen from the downstream side of the transport path in FIG. 1. FIG. 3 corresponds to a view of the chamber 7 of the coating device 4 as seen from the film supply unit 5 side. Note that the dotted line portion of the chamber 7 shown in FIG. 3 represents a part of the inside of the chamber 7. Further, in the following description, for convenience, the transport direction of the film F may be referred to as the X direction, the transport direction of the adherend W may be referred to as the Y direction, and the height direction (vertical direction) of the coating device 4 may be referred to as the Z direction.

[0020] As shown in FIGS. 1 and 2, the film supply unit 5 supports a film F for covering an adherend W. The film supply unit 5 includes a support base 50, a support roller 51, a take-up roller 52, a take-up roller 53, a guide roller 54, a cutting device 55, and the like. The support roller 51 provided on the support base 50 is a roller that rotatably supports the film F wound in a roll shape. The take-up rollers 52 and 53 are rollers for taking up a release film (protective film) when, for example, a release film or the like is laminated on the front and back surfaces of the film F to be covered on the adherend W. The guide roller 54 is a pair of rollers that pull out the film F supported by the support roller 51 in a planar shape. The cutting device 55 is a device for cutting the film F. In the present embodiment, the cutting device 55 has a cutter. Note that the cutting device 55 may be a device that cuts the film F by irradiating a laser, for example.

[0021] The film moving unit 6 performs a conveying operation of conveying the film F onto the adherend W conveyed into the chamber 7. Further, the film moving unit 6 moves the film F during the covering operation of covering the adherend W with the film F. Further, as shown in FIGS. 2 and 3, the film moving unit 6 is provided on an upper chamber member 71 described later and moves up and down in the Z direction together with the upper chamber member 71. As shown in FIGS. 1 to 3, the film moving unit 6 includes a tip gripping portion 60, a rear end gripping portion 61, a first moving mechanism 62, and a second moving mechanism 63.

[0022] The tip gripping part 60 grips the tip of the film F. The tip of the film F is the end portion drawn out in a direction orthogonal to the axial direction of the film F wound in a roll shape. The tip gripping part 60 grips both end portions of the film F in the Y direction at the tip of the film F. Note that the tip gripping part 60 may grip the entire width direction of the film F at the tip of the film F. Further, the tip gripping part 60 can be switched between a gripping state in which the tip of the film F is gripped and an open state in which the tip of the film F is not gripped and is opened. Further, the tip gripping part 60 is supported by a first moving mechanism 62 by a support member 622 that movably supports the tip gripping part 60.

[0023] The rear end gripping part 61 grips the rear end of the film F so that the film F covers the adherend W. As will be described later, with the tip gripping part 60 gripping the tip of the film F by the first moving mechanism 62, it moves so as to cover the adherend W. Thereafter, the rear end gripping part 61 grips the rear end of the film F. The rear end gripping part 61 grips both end portions of the film F in the Y direction at the rear end of the film F. Note that the rear end gripping part 61 may grip the entire width direction of the film F at the rear end of the film F. Further, the rear end gripping part 61 can be switched between a gripping state in which it grips the rear end drawn out in a direction orthogonal to the axial direction of the roll-shaped film F and an open state in which it does not grip the rear end of the film F and is opened. Further, the rear end gripping part 61 is supported by a second moving mechanism 63 by a support member 632 that movably supports the rear end gripping part 61.

[0024] The first moving mechanism 62 can move the tip gripping part 60 in the X direction (first direction) in which the film F is conveyed onto the adherend W and in the direction opposite to the X direction (second direction). Specifically, the first moving mechanism 62 includes a rail 620 that can move the tip gripping part 60 in the X direction (first direction) and in the direction opposite to the X direction (second direction). That is, it can also be said that the first moving mechanism 62 includes a guiding member that guides the movement of the tip gripping part 60 in the X direction (first direction) in which the film F is conveyed onto the adherend W and in the direction opposite to the X direction (second direction).

[0025] As shown in FIGS. 1 and 3, the rail 620 is provided on both side wall portions 71R to 71L outside the upper chamber member 71 of the chamber 7. Further, as shown in FIGS. 1 and 2, the rail 620 is provided along the X direction of the chamber 7 and is provided so as to protrude from the upper chamber member 71. That is, the rail 620 is longer than the upper chamber member 71 in the X direction. Thereby, as will be described later, when the upper chamber member 71 descends and abuts on the lower chamber member 72, the tip gripping portion 60 can be moved outside the chamber 7.

[0026] As shown in FIGS. 2 and 3, the first movement mechanism 62 includes a first control mechanism 621 inside the rail 620. The first control mechanism 621 may be, for example, an electric actuator, an electric cylinder, an electric ball screw mechanism, or the like. By controlling the first control mechanism 621, the support member 622 that supports the tip gripping portion 60 moves, so that the tip gripping portion 60 can move in the X direction and in the direction opposite to the X direction.

[0027] The second movement mechanism 63 can move the rear end gripping portion 61 in the X direction and in the direction opposite to the X direction. The second movement mechanism 63 includes a rail 630 that can move the rear end gripping portion 61 in the X direction and in the direction opposite to the X direction. That is, the second movement mechanism 63 can also be said to be a guide member that guides the movement of the rear end gripping portion 61 in the X direction and in the direction opposite to the X direction.

[0028] As shown in FIGS. 1 and 3, the rail 630 is provided on both side wall portions 71R to 71L outside the upper chamber member 71 of the chamber 7. Further, as shown in FIGS. 1 and 2, the rail 630 is provided along the X direction and is provided so as to protrude from the upper chamber member 71 toward the film supply unit 5 side (the film F supply source side). Thereby, as will be described later, when the upper chamber member 71 descends and abuts on the lower chamber member 72, the rear end gripping portion 61 can be moved outside the chamber 7.

[0029] As shown in FIG. 3, the second moving mechanism 63 includes a second control mechanism 631 inside the rail 630 for controlling the movement of the rear end gripping portion 61. The second control mechanism 63 may be a driving device such as an electric actuator, an electric cylinder, or an electric ball screw mechanism. By the control of the second control mechanism 631, the support member 632 that supports the rear end gripping portion 61 moves, so that the rear end gripping portion 61 can move in the X direction and the direction opposite to the X direction.

[0030] As shown in FIGS. 2 and 3, the coating device 4 includes an upper chamber member 71 and a lower chamber member 72 that define a coating space in which the adherend W is disposed.

[0031] The upper chamber member 71 has a front wall portion 71F, a rear wall portion 71B, a side wall portion 71R, a side wall portion 71L, and an upper wall portion 71U, and the lower surface is open. Rails 620 are provided on the side wall portion 71R and the side wall portion 71L. Further, rails 630 are provided on the side wall portion 71R and the side wall portion 71L. That is, the upper chamber member 71 is a member that movably supports the tip gripping portion 60 and the rear end gripping portion 61.

[0032] The lower chamber member 72 is provided below the upper chamber member 71, and the adherend W is disposed thereon. The lower chamber member 72 has a front wall portion 72F, a rear wall portion 72B, a side wall portion 72R, a side wall portion 72L, and a lower wall portion 72D, and the upper surface is open.

[0033] As shown in FIGS. 1 to 3, the coating device 4 has a displacement unit 9 that relatively displaces the upper chamber member 71 and the lower chamber member 72. The displacement unit 9 has, for example, a support member 90, a movement mechanism 91, and a rail 92. The support member 90 supports the upper chamber member 71 so as to be movable in the vertical direction of the coating device 4. The movement mechanism 91 moves the support member 90 in the vertical direction of the coating device 4. That is, the displacement unit 9 relatively displaces the first continuum 13 and the second continuum 14, which will be described later, and the adherend W by raising and lowering the upper chamber member 71. The movement mechanism 91 may be a driving device such as an electric actuator, an electric cylinder, or an electric ball screw mechanism. The rail 92 extends in the Z direction and is a member that guides the movement of the movement mechanism 91 in the Z direction. Further, when the upper chamber member 71 is lowered by the displacement unit 9 and comes into contact with the lower chamber member 72, the inside of the chamber 7 can be sealed. In the present embodiment, an example in which the displacement unit 9 raises and lowers the upper chamber member 71 with respect to the lower chamber member 72 has been described, but the present invention is not limited to this. For example, the displacement unit 9 may be configured to raise and lower the lower chamber member 72 with respect to the upper chamber member 71.

[0034] As shown in FIG. 1, the coating device 4 includes an adherend moving unit 10 inside the chamber 7. Here, refer to FIG. 4 in addition to FIGS. 1 to 3. FIG. 4 is a cross-sectional view of the chamber 7 for explaining the inside of the chamber 7 and corresponds to the view showing the inside of the chamber 7 in FIG. 2.

[0035] The adherend moving unit 10 is provided on the lower chamber member 72. The adherend moving unit 10 includes an adherend lifting unit 110 and an adherend conveying unit 111 supported by the adherend lifting unit 110. The adherend lifting unit 110 raises and lowers the adherend W carried into the chamber 7 in the vertical direction of the coating device 4 to adjust the position of the adherend W or bring the adherend W into contact with the film F. The adherend conveying unit 111 conveys the adherend W by a plurality of rotatable rollers. The adherend lifting unit 110 and the adherend conveying unit 111 may be actuators such as an electric cylinder or an electric ball screw mechanism.

[0036] As shown in FIG. 1, the coating device 4 includes a pressure adjustment unit 8 that adjusts the air pressure in the internal space of the chamber 7. The pressure adjustment unit 8 includes a pipe 80 communicating with the inside of the lower chamber member 72, a pipe 81 communicating with the inside of the upper chamber member 71, a decompression unit 82, a valve 820, and a valve 821. In the case of this embodiment, the decompression unit 82 includes a pump 822 and a decompression tank 823, and the decompression tank 823 is decompressed by the pump 822. The decompression unit 82 may be composed of only the pump 822. By providing the decompression tank 823, the inside of the chamber 7 can be decompressed by the decompression tank 823 in a relatively short time using a pump 822 with a relatively low output. The pipe 80 communicates with the decompression tank 823, and the pipe 81 communicates with the decompression tank 823 via the valve 821, the pipe 83, and the valve 820.

[0037] The valve 820 switches the communication state between the pipe 80 and the decompression tank 823. The valve 821 switches the communication state between the pipe 81, the pipe 83, and the pipe 84. The pipe 84 is open to the atmosphere. The valve 821 can be switched between a state where the pipe 81 communicates only with the pipe 83 and a state where the pipe 81 communicates only with the pipe 84.

[0038] As shown in FIG. 1, the coating device 4 includes a plurality of first abutting members 11, a plurality of second abutting members 12, a first continuum 13, and a second continuum 14 inside the chamber 7.

[0039] The plurality of first abutting members 11 are arranged along the first side of the film F conveyed on the adherend W and are members that abut against the first side. The plurality of second abutting members 12 are arranged along the second side of the film F facing the first side and are members that abut against the second side. The plurality of first abutting members 11 and the plurality of second abutting members 12 are arranged at positions facing each other. Note that the number of the plurality of first abutting members 11 and the plurality of second abutting members is not limited to the example shown in the figure and may be appropriately changed.

[0040] The first continuum 13 extends continuously in an extending direction along the first side of the film F, supports a plurality of first abutting members 11, and is a member deformable in an approaching / separating direction in which the plurality of first abutting members 11 approach and separate from the film F.

[0041] The second continuum 14 extends continuously in an extending direction along the second side of the film F, supports a plurality of second abutting members 12, and is a member deformable in an approaching / separating direction in which the plurality of second abutting members 12 approach and separate from the film F. The extending directions of the first continuum 13 and the second continuum 14 are the conveying direction of the film F.

[0042] In the covering operation, the displacement unit 9 described above relatively displaces the first continuum 13 and the second continuum 14 and the adherend W so that the film F abuts against the adherend W by the plurality of first abutting members 11 and the plurality of second abutting members 12.

[0043] In the present embodiment, the plurality of abutting members 11 and 12 that abut against the film F are supported by the deformable continua 13 and 14. Thereby, it is possible to suppress the abutting interval from becoming too large during the covering operation.

[0044] Here, refer to FIGS. 5 and 6. FIG. 5 is a diagram for explaining the inside of the chamber 7 and is a partially enlarged view in the X-direction view inside the chamber 7. Further, FIG. 6 is a diagram for explaining the inside of the chamber 7 and is a partially enlarged view in the Y-direction view inside the chamber 7.

[0045] As shown in FIGS. 5 and 6, the first continuum 13 and the second continuum 14 are chains. Further, the plurality of first abutting members 11 are rotating members rotatably supported by the first continuum 13. The plurality of second abutting members 12 are rotating members rotatably supported by the second continuum 14. The rotating member is, for example, a roller. By the member that abuts against the film F being a rotating member, it is possible to prevent the film F from being rubbed when the plurality of first abutting members 11 and the plurality of second abutting members 12 abut against the film F.

[0046] As shown in FIG. 5, each of the plurality of first abutting members 11 is provided on the first continuum 13 via a pressing member 15a and an elastic member 15b. Further, each of the plurality of second abutting members 12 is provided on the second continuum 14 via a pressing member 16a and an elastic member 16b.

[0047] The pressing member 15a is, for example, a member that presses the first abutting member 11 when the first abutting member 11 and the film F come into contact with each other. Further, the pressing member 16a is, for example, a member that presses the second abutting member 12 when the second abutting member 12 and the film F come into contact with each other. The pressing member 15a and the pressing member 16a may be, for example, actuators. Also, the elastic member 15b and the elastic member 16b may be, for example, springs. For example, depending on the adherend W, it may have a portion curved in a concave shape. When covering the adherend W with the film F, in the portion of the adherend W that is curved in a concave shape, it may be difficult for the respective abutting members 11, 12 to come into contact with the film F. On the other hand, by providing the pressing members 15a, 16a, when the respective abutting members 11, 12 come into contact with the film F, the contact between the respective abutting members 11, 12 and the film F can be supported.

[0048] As shown in FIG. 1, the covering device 4 includes a first suspension unit 17 and a second suspension unit 18 inside the chamber 7.

[0049] The first suspension unit 17 supports both ends of the first continuum 13 and suspends the first continuum 13 as shown in FIG. 4. The first suspension unit 17 includes a first fixing member 170 that fixes one end of the first continuum 13 inside the upper chamber member 71. Further, the first suspension unit 17 further includes a first adjusting device 171 that adjusts the slack of the first continuum 13. The first adjusting device 171 is, for example, an electric cylinder.

[0050] FIG. 4 shows the first suspension unit 17 on the side of the first continuum 13, and the same applies to the second suspension unit 18 on the side of the second continuum 14 (see FIGS. 1 and 3). That is, the second suspension unit 18 is provided inside the upper chamber member 71. The second suspension unit 18 includes a second fixing member 180 that fixes one end of the second continuum 14 inside the upper chamber member 71. The second suspension unit 18 further includes a second adjusting device 181 for adjusting the slack of the second continuum 14 (see FIG. 1). The second adjusting device 181 is, for example, an electric cylinder.

[0051] Since the slack of the first continuum 13 can be adjusted by the first adjusting device 171, the first continuum 13 can be made to follow the shape of the adherend W. Also, since the slack of the second continuum 14 can be adjusted by the second adjusting device 181, the second continuum 13 can be made to follow the shape of the adherend W.

[0052] Note that the first adjusting device 171 and the second adjusting device 181 may be, for example, a lifting mechanism provided on the upper wall portion 71U of the upper chamber member 71 and capable of moving up and down inside the upper chamber member 71.

[0053] Also, as shown in FIGS. 3 to 6, the coating device 4 further includes a first restricting unit 19. The first restricting unit 19 restricts displacement of the first continuum 13 in a direction different from the approaching / separating direction. A plurality of first restricting units 19 are arranged in the first extending direction, and include a rail 190 extending in the first approaching / separating direction and a slider 191 that engages with the rail 190 and the first continuum 13 and is displaceable along the rail 190. The first restricting unit 19 also includes a support member that supports the first continuum 13 in a deformable manner. The support member may be, for example, a sprocket.

[0054] By restricting the displacement of the first continuum 13 in a direction different from the approaching and separating direction by the first restricting unit 19, it is possible to suppress the displacement of the position of the first contacting member 11 when the first contacting member 11 first contacts the film F and when the contact is finally completed in the covering operation.

[0055] Further, the covering device 4 further includes a second restricting unit 20. The second restricting unit 20 restricts the displacement of the second continuum 14 in a direction different from the approaching and separating direction. A plurality of second restricting units 20 are arranged in the second extending direction, and include a rail 200 extending in the second approaching and separating direction, and a slider 201 engaged with the rail 200 and the second continuum 14 and displaceable along the rail 200. Further, the second restricting unit 20 includes a support member that supports the second continuum 14 in a deformable manner. The support member may be, for example, a sprocket.

[0056] By restricting the displacement of the second continuum 14 in a direction different from the approaching and separating direction by the second restricting unit 20, it is possible to suppress the displacement of the position of the second contacting member 12 when the second contacting member 12 first contacts the film F and when the contact is finally completed in the covering operation.

[0057] As shown in FIGS. 3 to 5, the covering device 4 includes a heating unit 21 that heats the film F conveyed onto the adherend W in the internal space of the chamber 7. The heating unit 21 generates heat, for example, by supplying power. The heat of the heating unit 21 softens the film F, and the adhesion of the film F to the adherend W can be improved.

[0058] The heating unit 21 is a heater 210 provided corresponding to each of the plurality of first abutting members 11. The coating device 4 includes a connecting member 22a that connects the heater 210 and the corresponding first abutting member 11 respectively. The connecting member 22a is provided so as to connect the heating unit 21 and the first continuum 13. Further, the heating unit 21 is also a heater 210 provided corresponding to each of the plurality of second abutting members 12. The coating device 4 includes a connecting member 22b that connects the heater 210 and the corresponding second abutting member 12 respectively. The connecting member 22b is provided so as to connect the heating unit 21 and the second continuum 14.

[0059] Since the heater 210 is connected to the corresponding abutting members 11 and 12 by the connecting members 22a and 22b, when the film F is brought into contact with the adherend W, it is possible to prevent the distance between the heater 210 and the abutting members 11 and 12 from increasing. Thereby, the heating amount of the film F does not vary significantly depending on the part of the adherend W, and it is possible to suppress a change in the elongation amount of the film F.

[0060] As shown in FIGS. 3 to 5, the coating device 4 includes a third continuum 23 and a fourth continuum 24. As described above, the plurality of first abutting members 11 and the plurality of second abutting members 12 are arranged at positions facing each other. The coating device 4 includes a bridge member 25 that connects the plurality of first abutting members 11 and the plurality of second abutting members 12. The heating unit 21 is provided for each combination of the plurality of first abutting members 11 and the plurality of second abutting members 12, and is provided on the bridge member 25. That is, the heating unit 21 is supported by the third continuum 23 and the fourth continuum 24.

[0061] The third continuum 23 extends continuously in a first extending direction along the first side of the film F. The third continuum 23 is, for example, a chain. The third continuum 23 is suspended by a third suspension unit 26 provided on the upper wall of the upper chamber member 71. The third suspension unit 26 is a unit that supports both ends of the third continuum 23 and suspends the third continuum 23. The third suspension unit 26 includes a third fixing member 260 that fixes one end of the third continuum 23, and a third adjusting device 261 that adjusts the slack of the third continuum 23. The third adjusting device 261 is, for example, an electric cylinder.

[0062] As described above, the heating unit 21 is connected to the corresponding first contact member 11 by the connecting member 22a. That is, the third continuum 23 is connected to the first continuum 13 via the connecting member 22a. Thereby, the third continuum 23 deforms in synchronization with the first continuum 13.

[0063] The fourth continuum 24 extends continuously in a second extending direction along the second side of the film F. The fourth continuum 24 is, for example, a chain. The fourth continuum 24 is suspended by a fourth suspension unit 27 provided on the upper wall of the upper chamber member 71. The fourth suspension unit 27 is a unit that supports both ends of the fourth continuum 24 and suspends the fourth continuum 24. The fourth suspension unit 27 includes a fourth fixing member 270 that fixes one end of the fourth continuum 24, and a fourth adjusting device 271 that adjusts the slack of the fourth continuum 24. The fourth adjusting device 271 is, for example, an electric cylinder.

[0064] As described above, the heating unit 21 is connected to the corresponding second contact member 12 by the connecting member 22b. That is, the fourth continuum 24 is connected to the second continuum 14 via the connecting member 22b. Thereby, the fourth continuum 24 deforms in synchronization with the second continuum 14.

[0065] <Operation example> An operation example of the coating system 1 will be described with reference to FIGS. 7 to 15. FIGS. 7 to 15 are explanatory diagrams of the operation of the coating device 4, and show an example of the operation of coating the film F on the adherend W from the loading of the film F and the adherend W to the unloading of the adherend W coated with the film F.

[0066] <Loading of the adherend, movement of the film> Refer to FIGS. 7 and 8. FIG. 7 shows a state in which the adherend W and the film F are conveyed inside the chamber 7. FIG. 8 shows the inside of the chamber 7 in the X direction of FIG. 7. As shown in FIGS. 7 and 8, the conveyance of the adherend W and the film F into the chamber 7 is performed in a state where the upper chamber member 71 is lifted by the displacement unit 9 and the upper chamber member 71 and the lower chamber member 72 are separated.

[0067] The adherend W is loaded, for example, onto the adherend moving unit 10 provided on the lower chamber member 72 by the above-described conveying device 3 or the like. The adherend moving unit 10 may adjust the position of the adherend W after the adherend W is loaded into the chamber 7. The film moving unit 6 conveys the film F onto the adherend W. Specifically, the leading end gripping portion 60 grips the leading end of the film F supplied from the film supply unit 5. Then, the leading end gripping portion 60 is moved in the X direction so as to cover the adherend W by the first moving mechanism 62. For example, the first control mechanism 621 provided on the first rail 620 may control the movement of the leading end gripping portion 60 based on the shape (size) of the adherend W.

[0068] <Cutting of the film, gripping of the film> Refer to FIG. 9. FIG. 9 shows the inside of the chamber 7 in the X direction. In FIG. 9, the rear end gripping portion 61 grips the film F, and the cutting device 55 shows the state where the film F has been cut. After the front end gripping portion 60 moves in the X direction so as to cover the adherend W with the film F, the rear end gripping portion 61 grips the rear end of the film F. Further, the cutting device 55 cuts the film F gripped by the front end gripping portion 60 and the rear end gripping portion 61 from the supply source of the film F (the roll-shaped film F). In this way, by cutting the film F from the supply source of the film F with the cutting device 55, it is possible to prevent the film F unnecessary for covering from being pulled out. The cutting device 55 may, for example, slide a cutter in the width direction of the film F to cut the film F. The width direction of the film F is the axial direction of the roll-shaped film F. Further, the cutting device 55 may lower a wide cutter provided along the width direction of the film F and press it against the film F in the thickness direction of the film F to cut the film F.

[0069] <Film conveying operation> Refer to FIG. 10. FIG. 10 shows the inside of the chamber 7 in the X direction. FIG. 10 shows the state where the film F gripped by the front end gripping portion 60 and the rear end gripping portion 61 has moved.

[0070] The front-end gripping portion 60 and the rear-end gripping portion 61 perform the conveyance operation of the film F. The front-end gripping portion 60 moves in the X direction by the first moving mechanism 62 while gripping the front end of the film F. The rear-end gripping portion 61 moves in the X direction by the second moving mechanism 63 while gripping the rear end of the film F. In the conveyance operation of conveying the film F in the X direction, the front-end gripping portion 60 and the rear-end gripping portion 61 move so as to apply tension to the film F. Note that the state of applying tension to the film F means a state of applying tension to such an extent that the film does not undergo plastic deformation or breakage. That is, the front-end gripping portion 60 and the rear-end gripping portion 61 convey the film F in a state where the film F is spread flat. Thereby, it is possible to prevent the film F from being covered on the adherend W in a state where wrinkles are generated in the film F. For example, the first control mechanism 621 may control the front-end gripping portion 60 to start moving in the X direction earlier than the rear-end gripping portion 61. Further, for example, before the conveyance operation is performed by the front-end gripping portion 60 and the rear-end gripping portion 61, the second control mechanism 631 may control the rear-end gripping portion 61 to move in a direction opposite to the X direction to apply tension to the film F.

[0071] <Contact operation> Refer to FIGS. 11 and 12. FIG. 11 shows a state where the coating device 4 is bringing the film F into contact with the adherend W. FIG. 12 shows the inside of the chamber 7 in the X direction of FIG. 11.

[0072] The displacement unit 9 relatively displaces the upper chamber member 71 and the lower chamber member 72. Specifically, the displacement unit 9 lowers the upper chamber member 71 toward the lower chamber member 72. When the upper chamber member 71 and the lower chamber member 72 are relatively displaced by the displacement unit 9, the plurality of first contact members 11 contact the first side of the film F, and the plurality of second contact members 12 contact the second side of the film F.

[0073] When a plurality of first abutting members 11 abut against the film F, the first continuum 13 deforms in a first approaching / separating direction in which the plurality of first abutting members 11 approach and separate from the film F. As shown in FIG. 11, the first continuum 13 can deform along a jig G having a placement surface along the shape of the adherend W. In FIG. 11, the configuration on the side of the first continuum 13 is shown, but the configuration on the side of the second continuum 14 is the same. That is, when a plurality of second abutting members 12 abut against the film F, the second continuum 14 deforms in a second approaching / separating direction in which the plurality of second abutting members 12 approach and separate from the film F. The second continuum 14 can deform along a jig G having a placement surface along the shape of the adherend W.

[0074] The plurality of first abutting members 11 are supported by a first continuum 13 that is deformable in a first approaching / separating direction in which the plurality of first abutting members 11 approach and separate from the film F. Thereby, the intervals at which the plurality of first abutting members 11 abut against the film F can be made substantially uniform. Also, the plurality of second abutting members 12 are supported by a second continuum 14 that is deformable in a second approaching / separating direction in which the plurality of second abutting members 12 approach and separate from the film F. Thereby, the intervals at which the plurality of second abutting members abut against the film F can be made substantially uniform. Therefore, it is possible to suppress a change in the amount of elongation of the film F depending on the part of the adherend W.

[0075] Also, the first continuum 13 and the second continuum 14 can deform along a jig G having a placement surface along the shape of the adherend W. Thereby, the plurality of first abutting members 11 and the plurality of second abutting members 12 can abut against the film F corresponding to the shape of the adherend W.

[0076] Here, it can also be said that the displacement unit 9 relatively displaces the first continuum 13 and the second continuum 14 and the adherend W by a plurality of first abutting members 11 and a plurality of second abutting members 12 so that the film F abuts on the adherend W. Further, it can also be said that the displacement unit 9 relatively displaces the tip gripping portion 60 and the adherend W so that the film F abuts on the adherend W. Further, it can also be said that the displacement unit 9 relatively displaces the film F gripped by the tip gripping portion 60 and the rear end gripping portion 61 and the adherend W by raising and lowering the upper chamber member 71.

[0077] Further, as shown in FIG. 11, after the film F and the adherend W start to abut, before the abutment is completed, the tip gripping portion 60 moves in a direction opposite to the X direction. That is, after the film F and the adherend W start to abut, the tip gripping portion 60 moves in a direction opposite to the X direction under the guidance of a guide member (rail 620). For example, when the film F and the adherend W start to abut, the first control mechanism 621 may control the support member 622 that supports the tip gripping portion 60 to move in a direction opposite to the X direction. Alternatively, the first control mechanism 621 may release the control of the movement of the tip gripping portion 60 to make the friction between the tip gripping portion 60 and the rail 620 small so that the tip gripping portion 60 can move by the tension of the film F. That is, the tip gripping portion 60 is not limited to moving by the first control mechanism 621, and may be in a form that moves in a direction opposite to the X direction due to the deformation of the film F when the film F covers the adherend W. Thus, when the film F and the adherend W abut, the tip gripping portion 60 moves in a direction opposite to the X direction. Thereby, it is possible to suppress the film F from being stretched between the tip of the film F and the portion where the film F abuts on the adherend W.

[0078] Also, after the film F and the adherend W start to contact, before the contact is completed, the rear-end gripping portion 61 moves in the X direction. For example, when the film F and the adherend W start to contact, the second control mechanism 631 may control the support member 632 that supports the rear-end gripping portion 61 to move in a direction opposite to the X direction. Alternatively, the second control mechanism 631 may release the control of the movement of the rear-end gripping portion 61 to make the friction between it and the rail 630 small so that the tip gripping portion 60 can move due to the tension of the film F. Thus, when the film F and the adherend W are in contact, the rear-end gripping portion 61 moves in the X direction. Thereby, it is possible to suppress the film F from being stretched between the rear end of the film F and the contact portion between the film F and the adherend W. Therefore, it is possible to further suppress the change in the amount of elongation of the film F depending on the part of the adherend W.

[0079] For example, it may be considered that the contact has started when a part of the film F contacts the adherend W. Also, after a part of the film F contacts the adherend W, it may be considered that the contact is completed when the film F covers the entire adherend W. Specifically, for example, it may be considered that the contact has started when the upper chamber member 71 is lowered to the first height with respect to the lower chamber member 72 by the displacement unit 9. Also, it may be considered that the contact is completed when the upper chamber member 71 is lowered to the second height lower than the first height with respect to the lower chamber member 72 by the displacement unit 9. The first height and the second height may be preset values depending on, for example, the size and shape of the adherend W.

[0080] Further, the tip gripping portion 60 and the rear end gripping portion 61 move so as to apply tension to the film F in the contact operation of bringing the film F into contact with the adherend W. For example, under the control of the first control mechanism 621, the tip gripping portion 60 may move in a direction opposite to the X direction at a speed slower than the speed at which the displacement unit 9 lowers the upper chamber member 71 and that does not interfere with the contact operation. Also, for example, under the control of the second control mechanism 631, the rear end gripping portion 61 may move in the X direction at a speed slower than the speed at which the displacement unit 9 lowers the upper chamber member 71 and that does not interfere with the contact operation. In this way, by moving the tip gripping portion 60 and the rear end gripping portion 61 so as to apply tension to the film F, it is possible to suppress the film F from getting wrinkled.

[0081] Also, as shown in FIGS. 11 and 12, in the present embodiment, the jig G has a first convex portion G1 extending along the first side of the film F, and a first contact portion G2 that is on the side opposite to the mounting surface side of the adherend W of the first convex portion G1 and has a lower height than the first convex portion G1. Further, the jig G has a second convex portion G3 extending along the second side of the film F, and a second contact portion G4 that is on the side opposite to the mounting surface side of the adherend W of the second convex portion G3 and has a lower height than the second convex portion G3. Then, as shown in FIG. 12, the plurality of first contact members 11 contact the first contact portion G2 via the film F, and the plurality of second contact members 12 contact the second contact portion G4 via the film F. By the plurality of first contact members 11 and the plurality of second contact members 12 contacting such parts of the jig G, the sealing performance of the sealed space surrounded by the film F and the jig G on which the adherend W is placed can be enhanced. Thereby, when adjusting the air pressure inside the chamber 7 by the air pressure adjustment unit 8 described later, the adhesion of the film F to the adherend W can be enhanced.

[0082] <Coating operation> Refer to FIGS. 13 and 14. FIG. 13 shows a state in which the film F is being coated on the adherend W. FIG. 14 shows the inside of the chamber 7 in the X direction of FIG. 13.

[0083] The first moving mechanism 62 can move the tip gripping portion 60 outside the upper chamber member 71 in the X direction because the rail 620 protrudes from the upper chamber member 71. After the plurality of first abutting members 11 and the plurality of second abutting members 12 have finished abutting against the film F, the tip gripping portion 60 releases the gripping of the film F and moves in the X direction so as to be located outside the upper chamber member 71. Also, the second moving mechanism 63 can move the rear end gripping portion 61 outside the upper chamber member 71 in the direction opposite to the X direction because the rail 630 protrudes toward the film supply unit 5 side. After the plurality of first abutting members 11 and the plurality of second abutting members 12 have finished abutting against the film F, the rear end gripping portion 61 releases the gripping of the film F and moves in the direction opposite to the X direction so as to be located outside the upper chamber member 71. Then, after the tip gripping portion 60 and the rear end gripping portion 61 have moved outside the upper chamber member 71, the displacement unit 9 lowers the upper chamber member 71 so that the upper chamber member 71 and the lower chamber member 72 come into contact with each other.

[0084] In this way, after the plurality of first abutting members 11 and the plurality of second abutting members 12 have finished abutting against the film F, the tip gripping portion 60 and the rear end gripping portion 61 release the gripping of the film F. Thereby, when the film F adheres to the adherend W due to the air pressure difference inside the chamber 7 by the air pressure adjustment unit 8 described later, it is possible to suppress the end portion of the film F from being stretched. Also, by the tip gripping portion 60 and the rear end gripping portion 61 moving outside the upper chamber member 71, it is also possible to prevent the tip gripping portion 60 and the rear end gripping portion 61 from coming into contact with the lower chamber member 72 when the upper chamber member 71 and the lower chamber member 72 are brought into contact with each other.

[0085] When the upper chamber member 71 and the lower chamber member 72 come into contact with each other and the inside of the chamber 7 is in a sealed state, the air pressure adjustment unit 8 adjusts the air pressure inside the chamber 7. Specifically, the air pressure adjustment unit 8 adjusts the air pressure between the sealed space surrounded by the film F and the jig G on which the adherend W is placed, and the outer space outside the sealed space, in the space (covered space) surrounded by the upper chamber member 71 and the lower chamber member 72. The air pressure adjustment unit 8, for example, reduces the pressure in the internal space of the chamber 7. Here, after switching the valve 821 to a state where the pipe 81 and the pipe 83 are in communication, the valve 820 is switched to a state where the pipe 83 and the decompression tank 823 are in communication. The air inside the internal space of the chamber 7 is exhausted from the pipes 81 and 83, and both the sealed space and the outer space are decompressed (see Fig. 1). Also, after closing the chamber 7, the heating unit 21 generates heat to heat the film F. The film F softens and becomes in a state where it is easy to stretch.

[0086] Next, the valve 821 is switched to a state where the pipe 81 and the pipe 84 are in communication. Among the internal space (covered space) of the chamber 7, the outer space above the film F is released to the atmosphere through the pipe 84, and an air pressure difference is generated between the sealed space and the outer space. Due to the air pressure difference, the film F is sucked toward the sealed space side. The adhesion degree of the film F to the adherend W increases, and the film F extends and adheres to the fine uneven shape of the adherend W. That is, the adherend W is covered by the film F. As described above, in the present embodiment, since the amount of elongation of the film F is suppressed from varying depending on the part of the adherend W, the amount of elongation of the film F is also suppressed from being biased depending on the part even during this adhesion. Note that the air pressure adjustment unit 8 may further include a configuration such as a compressor that pressurizes the outer space above the film F, and may be configured to increase the air pressure difference between the outer space and the sealed space when the adherend W is covered by the film F by pressurizing the outer space.

[0087] <Unloading operation> Refer to Fig. 15. Fig. 15 shows a state in which the adherend W covered with the film F is being carried out. Fig. 15 is a cross-sectional view showing the inside of the chamber 7 in the X direction. After the film F is covered on the adherend W, the displacement unit 9 raises the upper chamber member 71. After the upper chamber member 71 is raised, the adherend W covered with the film F by the film moving unit 6 is carried out of the chamber 7. The film moving unit 6 may adjust the height of the carrier table T so as to be aligned with the conveying device 3 when carrying out the adherend W, for example. Thus, the covering operation is completed. After this, trimming of the surplus portion of the film F covering the adherend W may be performed as necessary.

[0088] As described above, according to the present embodiment, after the film F and the adherend W start to contact, before the contact is completed, the tip gripping portion 60 moves in the direction opposite to the X direction. Thereby, it is suppressed that the amount of elongation of the film F varies depending on the part of the adherend W. Therefore, the generation of wrinkles can be prevented.

[0089] <Second Embodiment> Another configuration example of the coating device 4 will be described with reference to Figs. 16 to 18. Figs. 16 to 18 show other internal configurations of the coating device 4. Figs. 16 and 17 correspond to views of the chamber 7 of the coating device 4 seen from the film supply unit 5 side. Fig. 18 is a view of the coating device 4 seen from the downstream side of the conveying path in Fig. 1.

[0090] In the first embodiment, the configuration in which the third continuum 23 deforms synchronously with the first continuum 13 via the connecting member 22a and the fourth continuum 24 deforms synchronously with the second continuum 14 via the connecting member 22b was described. In the present embodiment, the third continuum 23 deforms independently of the first continuum 13, and the fourth continuum 24 deforms independently of the second continuum 14.

[0091] As shown in FIGS. 16 and 17, the coating device 4 includes a heater displacement unit 28 provided inside the upper chamber member 71. The heater displacement unit 28 is provided independently of the displacement unit 9. The heater displacement unit 28 supports the third continuum 23 and the fourth continuum 24 so that they can move up and down. Also, in the present embodiment, the first continuum 13 and the third continuum 23 are not connected. Further, the second continuum 14 and the fourth continuum 24 are not connected. For example, when heating the film F, the heater displacement unit 28 moves the third continuum 23 and the fourth continuum 24 up and down, so that the third continuum 23 deforms independently of the first continuum 13, and the fourth continuum deforms independently of the second continuum 14. That is, the heater displacement unit 28 can displace the heating unit 21 supported by the third continuum 23 and the fourth continuum with respect to the adherend W. Thereby, the heating position of the adherend W by the heating unit 21 can be adjusted as appropriate.

[0092] Also, as shown in FIG. 18, a plurality of heater displacement units 28 are provided in a first extending direction along the first side of the film F. Note that a plurality of heater displacement units 28 are provided in a second extending direction along the second side of the film F (not shown).

[0093] Also, as shown in FIGS. 16 and 17, for example, the heater displacement unit 28 includes a support member 281 that supports the third continuum 23, a moving mechanism 282 that moves the support member 281 in the vertical direction, and a rail 283 that guides the moving mechanism 282. Further, the heater displacement unit 28 includes a support member 284 that supports the fourth continuum 24, a moving mechanism 285 that moves the support member 284 in the vertical direction, and a rail 286 that guides the moving mechanism 285.

[0094] The support member 281 supports the third continuum 23 so that the third continuum 23 can be deformed. For example, the support member 281 may have a pair of rotating members and support the third continuum 23 by sandwiching it with the pair of rotating members. The support member 284 supports the fourth continuum 24 so that the fourth continuum 24 can be deformed. Similarly, the support member 284 may have a pair of rotating members and support the fourth continuum 24 by sandwiching it with the pair of rotating members. The rotating member may be, for example, a roller, a sprocket, etc. that can rotate about the Y direction axis.

[0095] The moving mechanisms 282 and 285 may be, for example, an actuator, an electric cylinder, an electric ball screw mechanism, etc. For example, the moving mechanism 282 and the moving mechanism 285 are provided at positions facing each other. FIG. 17 shows a state in which the heater displacement unit 28 has moved the third continuum 23 and the fourth continuum 24 upward inside the upper chamber member 71. Also, the moving mechanisms 282 and 285 may move the support member 281 and the support member 284 synchronously. In this way, by moving the third continuum 23 and the fourth continuum 24 in the vertical direction by the heater displacement unit 28, the heating unit 21 can be displaced relative to the adherend W.

[0096] Also, in the first embodiment, an example in which the separation distance between the first continuum 13 and the second continuum 14 is constant has been described, but a configuration in which the separation distance between the first continuum 13 and the second continuum 14 can be changed may also be used.

[0097] As shown in FIGS. 16 to 18, the coating device 4 includes a continuum moving unit 29 provided inside the upper chamber member 71. The continuum moving unit 29 moves at least one of the continua so that the separation distance between the first continuum 13 and the second continuum 14 changes. Thereby, the positions of the first continuum 13 and the second continuum 14 can be adjusted according to the size of the adherend W.

[0098] FIG. 17 shows, as an example, a state in which the continuum moving unit 29 moves the first continuum 13 in the Y direction and moves the second continuum 14 in the direction opposite to the Y direction. By moving in this way, the separation distance between the first continuum 13 and the second continuum 14 becomes closer. Also, for example, the continuum moving unit 29 may move only the first continuum 13 in the Y direction, or may move only the second continuum 14 in the direction opposite to the Y direction.

[0099] The continuum moving unit 29 includes, for example, a support member 291 that movably supports the first fixing member 170, and a support member 292 that movably supports the second fixing member 180. The support member 291 and the support member 292 are provided, for example, on a rail 293 extending in the Y direction provided inside the upper chamber member 71. The rail 293 guides, for example, the support member 291 and the support member 292 in the Y direction and the direction opposite to the Y direction. Also, the continuum moving unit 29 includes, for example, a moving mechanism 294 that can move at least one of the support member 291 and the support member 292 in the Y direction and the direction opposite to the Y direction. The moving mechanism 294 may be, for example, an actuator, an electric cylinder, an electric ball screw mechanism, or the like.

[0100] As shown in FIG. 18, the continuum moving unit 29 includes, for example, a support member 295 that movably supports the first adjusting device 171. Also, the continuum moving unit 29 includes a support member (not shown) that movably supports the second adjusting device 181. The support member 295 and the support member (not shown) are provided, for example, on a rail 297 extending in the Y direction provided inside the upper chamber member 71. Also, the continuum moving unit 29 includes, for example, a moving mechanism 298 that can move either the support member 295 or the support member (not shown) in the Y direction and the direction opposite to the Y direction. The moving mechanism 298 may be, for example, an actuator, an electric cylinder, an electric ball screw mechanism, or the like.

[0101] Although the moving mechanisms 294 and 298 are illustrated in this example as being supported by both side walls of the upper chamber member 71, the present invention is not limited to this. For example, a moving mechanism such as an actuator may be provided inside the rail 293. Further, for example, a moving mechanism such as an actuator may be provided inside the rail 297.

[0102] <Other Embodiments> In the above-described embodiment, an example in which the inside of the chamber 7 is depressurized by the pressure adjustment unit 8 and then opened to the atmosphere to coat the film F on the adherend W has been described. The method of coating the film F on the adherend W is not limited to this. For example, the film F may be coated on the adherend W without heating the film F. Further, the film F may be coated on the adherend W without depressurizing the inside of the chamber 7. For example, the film F may be pressurized with compressed air or the like from the surface of the film F opposite to the surface on the side of the adherend W to coat the film F on the adherend W. Alternatively, the film F may be coated on the adherend W by pressing the film F with a mold or the like.

[0103] Also, in the above-described embodiment, when the film F held by the tip holding portion 60 and the rear end holding portion 61 is brought into contact with the adherend W, an example in which a plurality of first contact members 11 contact the first side of the film and a plurality of second contact members contact the second side of the film has been described, but the present invention is not limited to this. For example, the coating device 4 may include a plurality of first gripping members arranged along the first side of the film F conveyed onto the adherend and gripping the first side, and a plurality of second gripping members arranged along the second side of the film F facing the first side and gripping the second side. Further, the coating device 4 may include a lifting unit that raises and lowers a plurality of first gripping members and a plurality of second gripping members along the shape of the adherend W. The coating device 4 may, for example, grip both sides of the film F held by the tip holding portion 60 and the rear end holding portion 61 with a plurality of first gripping members and a plurality of second gripping members. Then, when bringing the film into contact with the adherend W, the lifting unit may raise and lower the plurality of first gripping members and the plurality of second gripping members so that both sides of the film F are brought into contact with the adherend W.
