[0009] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the invention as claimed, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be combined in any desired manner. Furthermore, the same reference numerals are used to designate identical or similar components, and redundant descriptions will be omitted.

[0010] First Embodiment <Configuration of the covering system> 1 is a schematic diagram showing a part of the configuration of a coating system 1 to which the coating device of the present invention can be applied. In each drawing, arrows X and Y indicate horizontal directions that are orthogonal to each other, and arrow Z indicates the up-down direction (height direction of the coating device).

[0011] The coating system 1 is a decorating system that coats an adherend W with a film F to decorate the adherend W. The coating system 1 includes a control device 2, a conveying 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 memory 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 controls the coating system 1 by executing a program stored in the memory unit. The memory unit is a storage device such as a ROM, RAM, or HDD, and stores various control information in addition to the program executed by the processing unit. The input / output interface is an interface that sends 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 that the user uses to input instructions. The display unit and input unit may be configured as a touch panel.

[0013] The conveying device 3 carries 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 this embodiment, the conveying device 3 is a roller conveyor equipped with multiple rollers. The adherend W is held by a jig G placed on a conveying table T such as a pallet, and is conveyed by the conveying device 3 from the upstream conveying path 3a to the coating device 4. The adherend W is then coated with a film inside the chamber of the coating device 4, and then conveyed out from the downstream conveying path 3b. The conveying device 3 may further include, for example, a conveying position adjustment unit that adjusts the conveying position of the conveying table T. The conveying device 3 may also be various conveyors other than a roller conveyor, such as a belt conveyor, or may be an articulated robot.

[0014] The coating device 4 is a device that coats the adherend W with the film F. The coating device 4 is, for example, a vacuum forming device that utilizes a difference in air pressure to improve the adhesion of the film F to the adherend W. The coating device 4 will be described in detail later.

[0015] In this embodiment, the adherend W is described as being a component such as the front bumper or rear bumper of a vehicle (e.g., a four-wheeled vehicle), but the adherend W is not limited to these, and the present invention can be applied to a variety of objects.

[0016] In this embodiment, the film F is, for example, a film F made of a stretchable material, specifically a thermoplastic resin, and has a multilayer structure having, for example, a decorative layer on its surface that is provided with a color and pattern for decorating the adherend W, and an adhesive layer on its bottom layer. By covering the adherend W with such a film F, it is possible to decorate vehicle components according to, for example, the vehicle color.

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

[0018] <Coating device> Next, the coating device 4 will be described in detail. As shown in FIG. 1, the coating device 4 includes a film supply unit 5, a film moving unit 6, a chamber 7, and an air 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 moving unit 6. The dotted line portion of the chamber 7 shown in FIG. 1 represents the interior 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 air pressure inside the chamber 7 is adjusted by the air pressure adjustment unit 8.

[0019] Each component of the coating device 4 will be described below 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 diagram of the coating device 4 as seen from the downstream side of the conveyance path in Fig. 1. Fig. 3 corresponds to a diagram 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 part of the interior of the chamber 7. Furthermore, in the following description, for convenience, the conveyance direction of the film F may be referred to as the X direction, the conveyance direction of the adherend W as the Y direction, and the height direction (vertical direction) of the coating device 4 as the Z direction.

[0020] As shown in FIGS. 1 and 2, the film supply unit 5 supports the film F to be applied to the adherend W. The film supply unit 5 includes a support table 50, a support roller 51, a winding roller 52, a winding roller 53, a guide roller 54, and a cutting device 55. The support roller 51, which is provided on the support table 50, is a roller that rotatably supports the film F wound in a roll. The winding roller 52 and the winding roller 53 are rollers that wind up the release film, for example, when a release film (protective film) is laminated on the front and back surfaces of the film F to be applied to the adherend W. The guide roller 54 is a pair of rollers that pull out the film F supported by the support roller 51 into a flat shape. The cutting device 55 is a device that cuts the film F. In this embodiment, the cutting device 55 has a cutter. The cutting device 55 may be, for example, a device that cuts the film F by irradiating it with a laser.

[0021] The film moving unit 6 performs a transport operation to transport the film F onto the adherend W transported inside the chamber 7. The film moving unit 6 also moves the film F during a covering operation to cover the adherend W with the film F. As shown in FIGS. 2 and 3, the film moving unit 6 is provided in 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 leading end gripping section 60, a trailing end gripping section 61, a first moving mechanism 62, and a second moving mechanism 63.

[0022] The leading edge gripping section 60 grips the leading edge of the film F. The leading edge of the film F is the end portion pulled out in a direction perpendicular to the axial direction of the film F wound in a roll. The leading edge gripping section 60 grips both ends of the film F in the Y direction at the leading edge of the film F. The leading edge gripping section 60 may also grip the entire width of the film F at the leading edge of the film F. The leading edge gripping section 60 is switchable between a gripping state in which the leading edge of the film F is gripped and an open state in which the leading edge of the film F is open and not gripped. The leading edge gripping section 60 is supported by the first moving mechanism 62 by a support member 622 that movably supports the leading edge gripping section 60.

[0023] The rear end gripping section 61 grips the rear end of the film F so that the film F covers the adherend W. As described below, the first moving mechanism 62 causes the leading end gripping section 60 to move so that the film F covers the adherend W while gripping the leading end of the film F. Thereafter, the rear end gripping section 61 grips the rear end of the film F. The rear end gripping section 61 grips both ends of the film F in the Y direction at the rear end of the film F. Note that the rear end gripping section 61 may grip the entire width of the film F at the rear end of the film F. The rear end gripping section 61 is switchable between a gripping state in which it grips the rear end of the roll-shaped film F that has been pulled out in a direction perpendicular to the axial direction, and an open state in which it does not grip the rear end of the film F but opens it. The rear end gripping section 61 is supported by the second moving mechanism 63 by a support member 632 that movably supports the rear end gripping section 61.

[0024] The first movement mechanism 62 is capable of moving the leading end gripping part 60 in the X direction (first direction) in which the film F is conveyed onto the adherend W, and in a direction opposite to the X direction (second direction). Specifically, the first movement mechanism 62 includes a rail 620 that is capable of moving the leading end gripping part 60 in the X direction (first direction) and the direction opposite to the X direction (second direction). In other words, it can also be said that the first movement mechanism 62 includes a guide member that guides the movement of the leading end 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] 1 and 3, the rails 620 are provided on both side wall portions 71R to 71L on the exterior of the upper chamber member 71 of the chamber 7. Furthermore, as shown in FIGS. 1 and 2, the rails 620 are provided along the X direction of the chamber 7 and protrude from the upper chamber member 71. In other words, the rails 620 are longer in the X direction than the upper chamber member 71. This allows the tip gripping portion 60 to move to the exterior of the chamber 7 when the upper chamber member 71 descends and abuts against the lower chamber member 72, as will be described later.

[0026] 2 and 3, the first moving mechanism 62 includes a first control mechanism 621 inside a rail 620. The first control mechanism 621 may be, for example, an electric actuator, an electric cylinder, or an electric ball screw mechanism. The first control mechanism 621 controls the movement of a support member 622 that supports the tip gripping unit 60, thereby enabling the tip gripping unit 60 to move in the X direction and the direction opposite to the X direction.

[0027] The second movement mechanism 63 is capable of moving the rear end gripping portion 61 in the X direction and the direction opposite to the X direction. The second movement mechanism 63 includes a rail 630 that is capable of moving the rear end gripping portion 61 in the X direction and the direction opposite to the X direction. In other words, 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 the direction opposite to the X direction.

[0028] 1 and 3, rails 630 are provided on both side wall portions 71R-71L on the exterior of upper chamber member 71 of chamber 7. Furthermore, as shown in FIGS. 1 and 2, rails 630 are provided along the X direction and protrude from upper chamber member 71 toward the film supply unit 5 (the supply source side of film F). This allows rear end gripping portion 61 to move outside of chamber 7 when upper chamber member 71 descends and abuts against lower chamber member 72, as will be described later.

[0029] 3, the second movement mechanism 63 includes a second control mechanism 631 inside the rail 630 that controls the movement of the rear end gripping part 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. The second control mechanism 631 controls the movement of a support member 632 that supports the rear end gripping part 61, thereby making the rear end gripping part 61 movable in the X direction and the direction opposite to the X direction.

[0030] The coating apparatus 4 has an upper chamber member 71 and a lower chamber member 72 that constitute a chamber 7 that defines a coating space in which the adherend W is placed, as shown in FIGS.

[0031] The upper chamber member 71 has a front wall 71F, a rear wall 71B, side walls 71R and 71L, and an upper wall 71U, and is open on the bottom. Rails 620 are provided on the side walls 71R and 71L. Rails 630 are also provided on the side walls 71R and 71L. In other words, the upper chamber member 71 is a member that movably supports the leading end gripping portion 60 and the trailing end gripping portion 61.

[0032] The lower chamber member 72 is provided below the upper chamber member 71 and accommodates the adherend W. 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 bottom wall portion 72D, and is open at the top.

[0033] As shown in FIGS. 1 to 3 , the coating apparatus 4 has a displacement unit 9 that relatively displaces the upper chamber member 71 and the lower chamber member 72. The displacement unit 9 includes, 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 that it can move in the vertical direction of the coating apparatus 4. The movement mechanism 91 moves the support member 90 in the vertical direction of the coating apparatus 4. That is, the displacement unit 9 raises and lowers the upper chamber member 71, thereby relatively displacing the first and second continua 13 and 14 (described below) and the adherend W. The movement mechanism 91 may be, for example, 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 guides the movement of the movement mechanism 91 in the Z direction. Furthermore, the displacement unit 9 lowers the upper chamber member 71 and abuts against the lower chamber member 72, thereby sealing the interior of the chamber 7. In the present embodiment, an example has been described in which the displacement unit 9 raises and lowers the upper chamber member 71 relative to the lower chamber member 72, but this is not limiting. For example, the displacement unit 9 may be configured to raise and lower the lower chamber member 72 relative to the upper chamber member 71.

[0034] As shown in Fig. 1, the coating apparatus 4 includes an adherend transfer unit 10 inside a chamber 7. Here, Fig. 4 will be referred to in addition to Figs. 1 to 3. Fig. 4 is a cross-sectional view of the chamber 7 for explaining the interior of the chamber 7, and corresponds to the view showing the interior of the chamber 7 in Fig. 2.

[0035] The adherend moving unit 10 is provided in the lower chamber member 72. The adherend moving unit 10 includes an adherend lifting section 110 and an adherend conveying section 111 supported by the adherend lifting section 110. The adherend lifting section 110 lifts and lowers the adherend W carried into the chamber 7 in the vertical direction of the coating device 4, thereby adjusting the position of the adherend W or bringing the adherend W into contact with the film F. The adherend conveying section 111 conveys the adherend W using a plurality of rotatable rollers. The adherend lifting section 110 and the adherend conveying section 111 may be actuators such as electric cylinders or electric ball screw mechanisms, for example.

[0036] As shown in FIG. 1 , the coating apparatus 4 includes an air pressure adjustment unit 8 that adjusts the air pressure in the internal space of the chamber 7. The air pressure adjustment unit 8 includes a pipe 80 that communicates with the interior of the lower chamber member 72, a pipe 81 that communicates with the interior of the upper chamber member 71, a decompression unit 82, and valves 820 and 821. In 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 pressure inside the chamber 7 can be reduced in a relatively short time by using the decompression tank 823 and the pump 822, which has 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 valves 821, 83, and 820.

[0037] Valve 820 switches the communication state between pipe 80 and decompression tank 823. Valve 821 switches the communication state between pipe 81 and pipes 83 and 84. Pipe 84 is open to the atmosphere. Valve 821 can switch between a state in which pipe 81 is connected only to pipe 83 and a state in which pipe 81 is connected only to pipe 84.

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

[0039] The plurality of first contact members 11 are arranged along a first side edge of the film F transported onto the adherend W, and are members that abut against the first side edge. The plurality of second contact members 12 are arranged along a second side edge of the film F that faces the first side edge, and are members that abut against the second side edge. The plurality of first contact members 11 and the plurality of second contact members 12 are arranged in positions facing each other. Note that the number of the plurality of first contact members 11 and the plurality of second contact members is not limited to the example shown in the figure, and may be changed as appropriate.

[0040] The first continuum 13 is a member that extends continuously in an extension direction along the first side edge of the film F, supports a plurality of first abutment members 11, and is deformable in the contact / separation direction in which the plurality of first abutment members 11 contact and separate from the film F.

[0041] The second continuum 14 is continuously extended in the extension direction along the second side edge of the film F, supports the plurality of second abutting members 12, and is a member that is deformable in the contact / separation direction in which the plurality of second abutting members 12 contact and separate from the film F. The extension direction of the first continuum 13 and the second continuum 14 is the transport direction of the film F.

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

[0043] In this embodiment, a plurality of contact members 11, 12 that contact the film F are supported by deformable continuum members 13, 14. This makes it possible to prevent the contact interval from becoming too large during the covering operation.

[0044] Now, reference will be made to Figures 5 and 6. Figure 5 is a diagram illustrating the interior of the chamber 7, and is a partially enlarged view of the interior of the chamber 7 as viewed in the X direction. Figure 6 is a diagram illustrating the interior of the chamber 7, and is a partially enlarged view of the interior of the chamber 7 as viewed in the Y direction.

[0045] As shown in Figures 5 and 6, the first continuum 13 and the second continuum 14 are chains. The multiple first contact members 11 are rotating members rotatably supported on the first continuum 13. The multiple second contact members 12 are rotating members rotatably supported on the second continuum 14. The rotating members are, for example, rollers. By using rotating members as the members that come into contact with the film F, it is possible to prevent the film F from rubbing against the multiple first contact members 11 and the multiple second contact members 12 when they come into contact with the film F.

[0046] 5, each of the plurality of first contact members 11 is provided on the first continuum 13 via a pressing member 15a and an elastic member 15b. Each of the plurality of second contact 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 a member that presses the first contact member 11 when the first contact member 11 and the film F come into contact with each other. The pressing member 16a is a member that presses the second contact member 12 when the second contact member 12 and the film F come into contact with each other. The pressing members 15a and 16a may be, for example, actuators. The elastic members 15b and 16b may be, for example, springs. For example, some adherends W may have concavely curved portions. When the film F is applied to the adherend W, it may be difficult for the contact members 11 and 12 to come into contact with the film F at the concavely curved portions of the adherend W. On the other hand, by providing the pressing members 15a and 16a, it is possible to support the contact between the contact members 11 and 12 and the film F when the contact members 11 and 12 come into contact with the film F.

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

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

[0050] While FIG. 4 illustrates the first suspending unit 17 on the first continuum 13 side, the second suspending unit 18 on the second continuum 14 side is similar (see FIGS. 1 and 3). That is, the second suspending unit 18 is provided inside the upper chamber member 71. The second suspending 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 suspending unit 18 further includes a second adjusting device 181 that adjusts slack in the second continuum 14 (see FIG. 1). The second adjusting device 181 is, for example, an electric cylinder.

[0051] The first adjusting device 171 can adjust the slack of the first continuum 13, so that the first continuum 13 can be made to conform to the shape of the adherend W. Furthermore, the second adjusting device 181 can adjust the slack of the second continuum 14, so that the second continuum 13 can be made to conform to the shape of the adherend W.

[0052] The first adjustment device 171 and the second adjustment device 181 may be, for example, an elevating mechanism that is provided on the upper wall portion 71U of the upper chamber member 71 and can be raised and lowered in the vertical direction inside the upper chamber member 71.

[0053] 3 to 6, the covering device 4 further includes a first regulating unit 19. The first regulating unit 19 regulates displacement of the first continuum 13 in a direction different from the approaching / separating direction. The first regulating unit 19 includes a plurality of rails 190 arranged in the first extension direction and extending in the first approaching / separating direction, and a slider 191 that engages with the rails 190 and the first continuum 13 and is displaceable along the rails 190. The first regulating 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] The first regulating unit 19 regulates displacement of the first continuum 13 in a direction different from the direction of contact and separation, thereby preventing the position of the first abutment member 11 from shifting between when the first abutment member 11 first abuts the film F and when the abutment is finally completed during the covering operation.

[0055] The covering device 4 further includes a second regulating unit 20. The second regulating unit 20 regulates displacement of the second continuum 14 in a direction different from the approaching / separating direction. The second regulating unit 20 includes a plurality of rails 200 arranged in the second extension direction and extending in the second approaching / separating direction, and a slider 201 that engages with the rails 200 and the second continuum 14 and is displaceable along the rails 200. The second regulating unit 20 also includes a support member that supports the second continuum 14 in a deformable manner. The support member may be, for example, a sprocket.

[0056] The second regulating unit 20 regulates displacement of the second continuum 14 in a direction different from the direction of contact and separation, thereby preventing the position of the second abutment member 12 from shifting between when the second abutment member 12 first contacts the film F and when the abutment is finally completed during the covering operation.

[0057] As shown in FIGS. 3 to 5, the coating device 4 includes a heating unit 21 in the internal space of the chamber 7 that heats the film F transported onto the adherend W. The heating unit 21 generates heat, for example, when supplied with electricity. The heat from the heating unit 21 softens the film F, thereby improving the degree of adhesion of the film F to the adherend W.

[0058] The heating units 21 are heaters 210 provided corresponding to the plurality of first contact members 11, respectively. The coating apparatus 4 includes connecting members 22a that connect the heaters 210 to the corresponding first contact members 11, respectively. The connecting members 22a are provided to connect the heating units 21 to the first continuum 13. The heating units 21 are also heaters 210 provided corresponding to the plurality of second contact members 12, respectively. The coating apparatus 4 includes connecting members 22b that connect the heaters 210 to the corresponding second contact members 12, respectively. The connecting members 22b are provided to connect the heating units 21 to the second continuum 14.

[0059] Connecting members 22a, 22b connect heater 210 to the corresponding contact members 11, 12, thereby preventing the distance between heater 210 and each contact member 11, 12 from becoming large when film F is brought into contact with adherend W. This prevents the amount of heat applied to film F from varying significantly depending on the location on adherend W, and prevents changes in the amount of elongation of 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 contact members 11 and the plurality of second contact members 12 are arranged in positions facing each other. The coating device 4 includes a bridge member 25 that connects the plurality of first contact members 11 and the plurality of second contact members 12. A heating unit 21 is provided for each combination of the plurality of first contact members 11 and the plurality of second contact members 12, and is provided on the bridge member 25. In other words, 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 extension direction along the first side edge 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 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 adjustment device 261 that adjusts slack in the third continuum 23. The third adjustment 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. As a result, the third continuum 23 deforms in synchronization with the first continuum 13.

[0063] The fourth continuum 24 extends continuously in a second extension direction along the second side edge of the film F. The fourth continuum 24 is, for example, a chain. The fourth continuum 24 is suspended by a fourth hanging unit 27 provided on the upper wall of the upper chamber member 71. The fourth hanging unit 27 supports both ends of the fourth continuum 24 and suspends the fourth continuum 24. The fourth hanging 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 slack in 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 abutment 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. As a result, the fourth continuum 24 deforms in synchronization with the second continuum 14.

[0065] <Example of operation> An example of the operation of the coating system 1 will be described with reference to Figures 7 to 15. Figures 7 to 15 are explanatory diagrams of the operation of the coating device 4, showing an example of the operation from carrying in the film F and the adherend W, to coating the adherend W with the film F, and carrying out the adherend W coated with the film F.

[0066] <Transporting the adherend and moving the film> Please refer to Figures 7 and 8. Figure 7 shows the state in which the adherend W and the film F have been transported inside the chamber 7. Figure 8 shows the inside of the chamber 7 in the X direction of Figure 7. As shown in Figures 7 and 8, the transport of the adherend W and the film F into the chamber 7 is carried out in a state in which the upper chamber member 71 is raised by the displacement unit 9 and the upper chamber member 71 and the lower chamber member 72 are separated from each other.

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

[0068] <Cutting and gripping of film> Refer to FIG. 9. FIG. 9 shows the interior of the chamber 7 in the X direction. FIG. 9 shows a state in which the rear end gripping portion 61 grips the film F and the cutting device 55 cuts the film F. After the leading 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. The cutting device 55 also cuts the film F gripped by the leading end gripping portion 60 and the rear end gripping portion 61 from the source of the film F (rolled film F). By cutting the film F from the source of the film F using the cutting device 55 in this way, it is possible to prevent 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 rolled film F. The cutting device 55 may also cut the film F by lowering a wide cutter provided along the width direction of the film F and pressing it against the thickness direction of the film F.

[0069] <Film transport operation> Please refer to Figure 10. Figure 10 shows the inside of chamber 7 in the X direction. Figure 10 shows a state in which film F gripped by leading end gripping portion 60 and trailing end gripping portion 61 has moved.

[0070] The leading edge gripping portion 60 and the trailing edge gripping portion 61 transport the film F. The leading edge gripping portion 60, while gripping the leading edge of the film F, is moved in the X direction by a first moving mechanism 62. The trailing edge gripping portion 61, while gripping the trailing edge of the film F, is moved in the X direction by a second moving mechanism 63. When transporting the film F in the X direction, the leading edge gripping portion 60 and the trailing edge gripping portion 61 move so as to apply tension to the film F. Note that applying tension to the film F refers to applying tension to the film F to an extent that does not cause plastic deformation or breakage. In other words, the leading edge gripping portion 60 and the trailing edge gripping portion 61 transport the film F while spreading the film F flat. This prevents the film F from being covered by the adherend W if the film F is wrinkled. For example, the first control mechanism 621 may control the leading edge gripping portion 60 to start moving in the X direction before the trailing edge gripping portion 61. Furthermore, for example, before the leading end gripping portion 60 and the trailing end gripping portion 61 perform the conveying operation, the second control mechanism 631 may control the trailing end gripping portion 61 to move in the direction opposite to the X direction, thereby applying tension to the film F.

[0071] <Contact operation> Please refer to Figures 11 and 12. Figure 11 shows a state in which the coating device 4 is bringing the film F into contact with the adherend W. Figure 12 shows the inside of the chamber 7 in the X direction of Figure 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 abutting members 11 abut against a first side edge of the film F, and the plurality of second abutting members 12 abut against a second side edge of the film F.

[0073] When the multiple first contact members 11 contact the film F, the first continuum 13 deforms in a first contact-separation direction in which the multiple first contact members 11 contact and separate from the film F. As shown in FIG. 11 , the first continuum 13 is deformable along a jig G having a mounting surface that conforms to the shape of the adherend W. While FIG. 11 shows the configuration of the first continuum 13, the configuration of the second continuum 14 is similar. That is, when the multiple second contact members 12 contact the film F, the second continuum 14 deforms in a second contact-separation direction in which the multiple second contact members 12 contact and separate from the film F. The second continuum 14 is deformable along a jig G having a mounting surface that conforms to the shape of the adherend W.

[0074] The multiple first contact members 11 are supported by a first continuum 13 that is deformable in a first contact-separation direction in which the multiple first contact members 11 contact and separate from the film F. This makes it possible to make the intervals at which the multiple first contact members 11 contact the film F approximately uniform. Furthermore, the multiple second contact members 12 are supported by a second continuum 14 that is deformable in a second contact-separation direction in which the multiple second contact members 12 contact and separate from the film F. This makes it possible to make the intervals at which the multiple second contact members contact the film F approximately uniform. Therefore, it is possible to prevent the amount of elongation of the film F from varying depending on the location on the adherend W.

[0075] Furthermore, the first continuum 13 and the second continuum 14 can be deformed along the jig G having a mounting surface that conforms to the shape of the adherend W. This allows the multiple first contact members 11 and the multiple second contact members 12 to contact the film F in accordance with the shape of the adherend W.

[0076] Here, it can be said that the displacement unit 9 relatively displaces the first continuum 13, the second continuum 14, and the adherend W using the multiple first contact members 11 and the multiple second contact members 12 so that the film F contacts the adherend W. It can also be said that the displacement unit 9 relatively displaces the front end gripping portion 60 and the adherend W so that the film F contacts the adherend W. It can also be said that the displacement unit 9 relatively displaces the film F gripped by the front end gripping portion 60 and the rear end gripping portion 61 and the adherend W by raising and lowering the upper chamber member 71.

[0077] 11, after the film F and the adherend W start to contact each other, but before the contact is complete, the tip gripping portion 60 moves in the direction opposite to the X-direction. That is, after the film F and the adherend W start to contact each other, the tip gripping portion 60 moves in the direction opposite to the X-direction guided by a guide member (rail 620). For example, when the film F and the adherend W start to contact each other, the first control mechanism 621 may control the support member 622 supporting the tip gripping portion 60 to move in the direction opposite to the X-direction. Alternatively, the first control mechanism 621 may release the control over the movement of the tip gripping portion 60, reducing friction with the rail 620 so that the tip gripping portion 60 can move due to the tension of the film F. That is, the movement of the tip gripping portion 60 is not limited to being controlled by the first control mechanism 621, and the tip gripping portion 60 may also move in the direction opposite to the X-direction due to deformation of the film F as it covers the adherend W. In this way, when the film F comes into contact with the adherend W, the tip gripping portion 60 moves in the direction opposite to the X direction. This makes it possible to prevent the film F from being stretched between the tip of the film F and the portion where the film F comes into contact with the adherend W.

[0078] Furthermore, after the film F and the adherend W begin to contact each other, the rear end gripping portion 61 moves in the X direction before the contact is completed. For example, when the film F and the adherend W begin to contact each other, the second control mechanism 631 may control the support member 632 supporting the rear end gripping portion 61 to move in the direction opposite to the X direction. Alternatively, the second control mechanism 631 may release control over the movement of the rear end gripping portion 61, reducing friction with the rail 630 so that the front end gripping portion 60 can move due to the tension of the film F. In this way, when the film F and the adherend W come into contact, the rear end gripping portion 61 moves in the X direction. This makes it possible to prevent the film F from being stretched between the rear end of the film F and the contact portion of the film F with the adherend W. This further prevents the amount of stretch of the film F from varying depending on the location on the adherend W.

[0079] For example, the start of contact may be determined when a portion of the film F contacts the adherend W. Alternatively, the completion of contact may be determined when the film F covers the entire adherend W after a portion of the film F contacts the adherend W. Specifically, the start of contact may be determined when the displacement unit 9 lowers the upper chamber member 71 to a first height relative to the lower chamber member 72. Alternatively, the completion of contact may be determined when the displacement unit 9 lowers the upper chamber member 71 to a second height, which is lower than the first height, relative to the lower chamber member 72. The first height and the second height may be values ​​that are set in advance depending on, for example, the size and shape of the adherend W.

[0080] Furthermore, the leading end gripping portion 60 and the trailing end gripping portion 61 move so as to apply tension to the film F during the contact operation in which the film F is brought into contact with the adherend W. For example, under control of the first control mechanism 621, the leading end gripping portion 60 may move in the 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 at a speed that does not interfere with the contact operation. Also, under control of the second control mechanism 631, the trailing 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 at a speed that does not interfere with the contact operation. In this way, by moving the leading end gripping portion 60 and the trailing end gripping portion 61 so as to apply tension to the film F, it is possible to prevent wrinkling of the film F.

[0081] 11 and 12, in this embodiment, the jig G has a first protrusion G1 extending along a first side edge of the film F and a first contacted portion G2 located on the opposite side of the first protrusion G1 from the side on which the adherend W is placed and which is lower in height than the first protrusion G1. The jig G also has a second protrusion G3 extending along a second side edge of the film F and a second contacted portion G4 located on the opposite side of the second protrusion G3 from the side on which the adherend W is placed and which is lower in height than the second protrusion G3. As shown in FIG. 12, the multiple first contact members 11 contact the first contacted portion G2 via the film F, and the multiple second contact members 12 contact the second contacted portion G4 via the film F. The contact of the first contact members 11 and the second contact members 12 with such portions of the jig G can improve the airtightness of the sealed space surrounded by the film F and the jig G on which the adherend W is placed. This can improve the adhesion of the film F to the adherend W when the air pressure inside the chamber 7 is adjusted by the air pressure adjustment unit 8, which will be described later.

[0082] <Covering operation> Please refer to Figures 13 and 14. Figure 13 shows a state in which the film F is being coated on the adherend W. Figure 14 shows the inside of the chamber 7 in the X direction of Figure 13.

[0083] The first moving mechanism 62 has a rail 620 protruding from the upper chamber member 71, which allows the leading end gripping portion 60 to move outward from the upper chamber member 71 in the X direction. After the plurality of first contact members 11 and the plurality of second contact members 12 have come into contact with the film F, the leading end gripping portion 60 releases its grip on the film F and moves in the X direction to be positioned outward from the upper chamber member 71. The second moving mechanism 63 has a rail 630 protruding toward the film supply unit 5, which allows the trailing end gripping portion 61 to move outward from the upper chamber member 71 in the direction opposite to the X direction. After the plurality of first contact members 11 and the plurality of second contact members 12 have come into contact with the film F, the trailing end gripping portion 61 releases its grip on the film F and moves in the direction opposite to the X direction to be positioned outward from the upper chamber member 71. Then, after the leading end gripping portion 60 and the trailing end gripping portion 61 have moved to the outside of 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 contact members 11 and the plurality of second contact members 12 have come into contact with the film F, the leading edge gripping portion 60 and the trailing edge gripping portion 61 release their grip on the film F. This makes it possible to prevent the end of the film F from being stretched when the air pressure adjustment unit 8, described below, causes the film F to adhere to the adherend W due to the air pressure difference inside the chamber 7. Furthermore, by moving the leading edge gripping portion 60 and the trailing edge gripping portion 61 to the outside of the upper chamber member 71, it is also possible to prevent the leading edge gripping portion 60 and the trailing edge 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 interior of the chamber 7 is sealed, 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 the valve 821 is switched to a state that connects the pipe 81 to the pipe 83, the valve 820 is switched to a state that connects the pipe 83 to the decompression tank 823. The air in the internal space of the chamber 7 is exhausted through the pipes 81 and 83, and both the sealed space and the outer space are reduced in pressure (see FIG. 1). After the chamber 7 is closed, the heating unit 21 generates heat to heat the film F. The film F softens and becomes more easily stretchable.

[0086] Next, valve 821 is switched to a state in which pipe 81 and pipe 84 communicate with each other. Of the internal space (covered space) of chamber 7, the outer space above film F is opened to the atmosphere via pipe 84, creating a pressure difference between the sealed space and the outer space. The pressure difference causes film F to be sucked toward the sealed space. The adhesion of film F to adherend W increases, and film F stretches and adheres to the fine unevenness of the adherend W. In other words, adherend W is covered by film F. As described above, in this embodiment, the amount of stretch of film F is prevented from varying depending on the region of adherend W, so that unevenness in the amount of stretch of film F during this adhesion is also prevented from occurring depending on the region. Note that air pressure adjustment unit 8 may further include a compressor or other component that pressurizes the outer space above film F, and by pressurizing the outer space, the pressure difference between the outer space and the sealed space when adherend W is covered by film F is increased.

[0087] <Exporting operation> Please refer to FIG. 15. FIG. 15 shows the state in which the adherend W coated with the film F is being transported out. FIG. 15 is a cross-sectional view showing the inside of the chamber 7 in the X direction. After the film F has been coated on the adherend W, the displacement unit 9 raises the upper chamber member 71. After the upper chamber member 71 has been raised, the adherend W coated with the film F is transported out of the chamber 7 by the film moving unit 6. For example, when transporting the adherend W out, the film moving unit 6 may adjust the height of the transport table T so that it is aligned with the transport device 3. This completes the coating operation. Thereafter, if necessary, excess portions of the film F coating the adherend W may be trimmed.

[0088] As described above, according to this embodiment, after the film F and the adherend W start to contact each other, the leading end gripping portion 60 moves in the direction opposite to the X direction before the contact is completed. This prevents the amount of stretch of the film F from varying depending on the location of the adherend W. This makes it possible to prevent wrinkles from occurring.

[0089] Second Embodiment Other configuration examples of the coating device 4 will be described with reference to Figures 16 to 18. Figures 16 to 18 show other internal configurations of the coating device 4. Figures 16 and 17 correspond to views of the chamber 7 of the coating device 4 as seen from the film supply unit 5 side. Figure 18 is a view of the coating device 4 as seen from the downstream side of the transport path in Figure 1.

[0090] In the first embodiment, the third continuum 23 deforms in synchronization with the first continuum 13 via the connecting member 22a, and the fourth continuum 24 deforms in synchronization with the second continuum 14 via the connecting member 22b. 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 apparatus 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 be raised and lowered. In this embodiment, the first continuum 13 and the third continuum 23 are not connected, and the second continuum 14 and the fourth continuum 24 are not connected. For example, when heating the film F, the heater displacement unit 28 raises and lowers the third continuum 23 and the fourth continuum 24, causing the third continuum 23 to deform independently of the first continuum 13, and the fourth continuum to deform independently of the second continuum 14. That is, the heater displacement unit 28 can displace the heating unit 21, which is supported by the third continuum 23 and the fourth continuum, relative to the adherend W. This allows the heating position of the adherend W by the heating unit 21 to be adjusted appropriately.

[0092] 18, a plurality of heater displacement units 28 are provided in a first extension direction along a first side edge of the film F. A plurality of heater displacement units 28 are provided in a second extension direction along a second side edge of the film F (not shown).

[0093] 16 and 17, for example, the heater displacement unit 28 has a support member 281 that supports the third continuum 23, a movement mechanism 282 that moves the support member 281 in the vertical direction, and a rail 283 that guides the movement mechanism 282. The heater displacement unit 28 also has a support member 284 that supports the fourth continuum 24, a movement mechanism 285 that moves the support member 284 in the vertical direction, and a rail 286 that guides the movement mechanism 285.

[0094] The support member 281 supports the third continuum 23 so that the third continuum 23 is deformable. For example, the support member 281 may have a pair of rotating members and support the third continuum 23 by sandwiching it between the pair of rotating members. The support member 284 supports the fourth continuum 24 so that the fourth continuum 24 is deformable. Similarly, the support member 284 may have a pair of rotating members and support the fourth continuum 24 by sandwiching it between the pair of rotating members. The rotating members may be, for example, rollers or sprockets that are rotatable about an axis in the Y direction.

[0095] The moving mechanism 282 and the moving mechanism 285 may be, for example, an actuator, an electric cylinder, an electric ball screw mechanism, or the like. For example, the moving mechanism 282 and the moving mechanism 285 are provided in 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. The moving mechanism 282 and the moving mechanism 285 may also move the support member 281 and the support member 284 synchronously. In this way, the heater displacement unit 28 moves the third continuum 23 and the fourth continuum 24 up and down, thereby displacing the heating unit 21 relative to the adherend W.

[0096] Furthermore, in the first embodiment, an example was described in which the separation distance between the first continuum 13 and the second continuum 14 was constant, but the separation distance between the first continuum 13 and the second continuum 14 may be variable.

[0097] 16 to 18, the coating apparatus 4 includes a continuum movement unit 29 provided inside an upper chamber member 71. The continuum movement unit 29 moves at least one of the first continuum 13 and the second continuum 14, for example, so as to change the distance between them. This makes it possible to adjust the positions of the first continuum 13 and the second continuum 14 according to the size of the adherend W.

[0098] 17 shows an example in which the continuum movement 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 them in this manner, the separation distance between the first continuum 13 and the second continuum 14 becomes closer. Also, for example, the continuum movement 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 movement unit 29 includes, for example, a support member 291 that movably supports the first fixed member 170, and a support member 292 that movably supports the second fixed member 180. The support members 291 and 292 are provided on, for example, rails 293 that are provided inside the upper chamber member 71 and extend in the Y direction. The rails 293 guide, for example, the support members 291 and 292 in the Y direction and the direction opposite to the Y direction. The continuum movement unit 29 also includes, for example, a movement mechanism 294 that can move at least one of the support members 291 and 292 in the Y direction and the direction opposite to the Y direction. The movement mechanism 294 may be, for example, an actuator, an electric cylinder, an electric ball screw mechanism, or the like.

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

[0101] In this example, the moving mechanisms 294 and 298 are illustrated as being supported on both side walls of the upper chamber member 71, but this is not limiting. For example, a moving mechanism such as an actuator may be provided inside the rail 293. Also, 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 has been described in which the interior of chamber 7 is depressurized by air pressure adjustment unit 8 and then opened to the atmosphere, and film F is then coated on adherend W. The method of coating adherend W with film F is not limited to this. For example, film F may be coated on adherend W without heating. Also, film F may be coated on adherend W without depressurizing the interior of chamber 7. For example, film F may be coated on adherend W by pressurizing film F with compressed air or the like from the side of film F opposite to the side facing adherend W. Alternatively, film F may be coated on adherend W by pressing it against a mold or the like.

[0103] In the above-described embodiment, when the film F gripped by the leading end gripping portion 60 and the trailing end gripping portion 61 is brought into contact with the adherend W, the multiple first contact members 11 contact the first side edge of the film and the multiple second contact members contact the second side edge of the film. However, this is not limiting. For example, the covering device 4 may include multiple first gripping members arranged along the first side edge of the film F transported onto the adherend and gripping the first side edge, and multiple second gripping members arranged along the second side edge of the film F opposite the first side edge and gripping the second side edge. The covering device 4 may also include an elevation unit that raises and lowers the multiple first gripping members and multiple second gripping members in accordance with the shape of the adherend W. The covering device 4 may, for example, use a plurality of first gripping members and a plurality of second gripping members to grip both side edges of the film F gripped by the leading end gripping portion 60 and the trailing end gripping portion 61. When the film F is to be brought 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 to bring both side edges of the film F into contact with the adherend W.
