Description

  The present invention relates to an apparatus for attaching a film to the surface of an adherend and a method for producing a film sticker, and in particular, a film sticking apparatus capable of suppressing poor sticking and obtaining a good sticking state, and It is related with the manufacturing method of a film sticking body.

  In recent years, for example, a film having a coating-like design layer is often applied to the surface of an adherend such as a vehicle body, a door panel, or a fender. Such a film sticking process can be roughly divided into two methods. One is a dry sticking method and the other is a water sticking method. The dry pasting method is a method in which a film having an adhesive layer or an adhesive layer on the back surface is directly pasted on the surface of an adherend without using a construction liquid (Patent Document 1), and the water pasting method is a surfactant. After the applied construction liquid is applied to the back side of the film, the film is brought into close contact with the surface of the adherend using a squeegee, and then the pressure is applied between the adherend surface and the film with a squeegee to extract the construction liquid. This is a method of attaching a film to an adherend.

However, in any of the construction methods, a manual operation requiring a delicate sensation of the hand is required to adapt the film to the delicate curved surface shape of the adherend surface. In addition, the dry pasting method needs to be carefully positioned and carefully stuck little by little while preventing wrinkles and air bites with a squeegee, and includes a highly skilled work process. In addition, the water pasting method has many man-hours and is complicated, and the construction liquid tends to remain under the film, and there are also problems in the preparation of the construction liquid and the working environment when using the construction liquid.

Hereinafter, while describing embodiment of the sticking apparatus of this invention, referring a figure, the manufacturing method and film of a film sticking body are demonstrated. In addition, although the form shown by a figure is a preferable form of this invention, this invention is not limited.
(Attaching device)
The sticking apparatus of the present invention sticks a film to various panels of a vehicle, that is, a panel of each part such as a door, a front body, and a rear body, an adherend such as an interior / exterior panel of a building, a surface panel of furniture, and the like. This is a preferred sticking device for wearing. The film is not particularly limited, but a film having a pressure-sensitive adhesive layer made of a pressure-sensitive adhesive or an adhesive on the back surface can be preferably used. The preferable 1st form of the sticking apparatus of this invention is shown by FIGS. This sticking apparatus 2 is for sticking a rectangular (here, rectangular) film body 100 with a door panel of a vehicle such as an automobile as an adherend H. Hereinafter, the basic form of the sticking apparatus of this invention is demonstrated, referring suitably the sticking apparatus 2 shown in FIGS.
(First form)
The sticking device 2 includes a film support portion 4, a pressure-bonding member 24, and a pressure-bonding member guide portion 44. As shown in FIG. 1, the sticking device 2 has an outer shape that roughly matches the shape of the film 1 to be stuck, has a film support portion 4 at the lower stage, and a crimping member 24 at the upper stage. The held crimping member guide portion 44 is combined.
(Film support part)
As shown in FIG. 2, the film support part 4 should just be able to support the adhesion surface of the film 1 on the surface of a to-be-adhered body in the opposing state, Although the form is not specifically limited, The film 1 which is going to stick is attached. It is preferable to have a frame 6 that can be fixed. The frame 6 is preferably provided with means for fixing two sides corresponding to one end side and the other end side of the movement range of the crimping member 24. Since the film 1 is fixed in such a direction, the film 1 can be sequentially crimped to the surface of the adherend H easily as the crimping member 24 moves. More preferably, in addition to these two sides, the film support part 4 preferably further includes a fixing means for fixing a side corresponding to one end side and / or the other end side along the moving direction of the crimping member 24. . By providing such lateral fixing means, the film 1 is brought into contact with the surface of the adherend H even when the surface of the adherend H along the lateral direction has a curved surface and is uneven. Without being in close proximity to the surface. The position where the fixing means on the side is formed can be selected such that the film 1 can be supported to the extent that the film 1 is not brought into contact with the surface of the adherend H.

  In the sticking apparatus 2, the film support 4 has a square frame 6, and a hole formed in the film 1 as a fixing means for fixing the upper and lower ends of the film 1 in the upper and lower frames. Are provided with a plurality of pin-like convex portions 8 and 10. In addition, the left and right frame bodies each have a pin-like protrusion that can lock the hole formed in the film 1 as a fixing means for fixing the approximate center of the length of the film 1 along the frame body. Parts 12 and 14 are provided. The means for fixing the frame 6 and the film 1 is not limited to the illustrated latching structure with the hole and the projection, and those skilled in the art, such as using an adhesive or pressure-sensitive adhesive, or a clamping form, may be used. Means that can be normally used can be adopted, and a structure that achieves such fixing can be provided on the film 1 side and the frame side as appropriate. In addition, the preferable form of the film 1 used for the sticking apparatus of this invention is mentioned later.

Further, in the sticking device 2, a plurality of fixing means are provided for the upper and lower frame bodies of the frame 6, and a single fixing means is provided for the left and right frame bodies. However, this is limited to such a combination of numbers. Instead, it can be appropriately changed according to the shape and size of the film 1 and the surface shape of the adherend 1. Further, the surface of the film support 4 that faces the adherend H can be formed in advance along the surface shape of the adherend H. By doing so, the positioning with respect to the surface of the adherend H can be easily performed.
(Crimping member)
The shape of the crimping member 24 is not particularly limited as long as it presses the film 1 against the surface of the adherend H, but preferably, the crimping member 24 is along a direction orthogonal to the moving direction of the crimping member 24 of the film 1. It has the press part 26 of the length corresponding to the width | variety (henceforth a sticking width | variety) of the film 1. FIG. By having the pressing portion 26 having a length corresponding to the sticking width, the entire sticking width is simultaneously pressed by moving the crimping member 24 along a predetermined moving direction. Since it is crimped, wrinkles, kinks, and air biting can be efficiently suppressed. The pressing part 26 includes a pressing surface 26a that directly contacts the film.

  It is preferable that the pressing portion 26 has flexibility so as to follow the surface of the adherend H. Such flexibility is provided, for example, by forming at least the pressing surface 26a of the pressing portion 26 with a plastic material having moderate flexibility or an elastic material having resilience.

  The crimping member 24 can be a squeegee-like body that slides on the surface of the adherend H, or a rotatable roller-like body that rotates and moves on the surface of the adherend H. The squeegee-like body includes a plate-like pressing portion 26, and the tip thereof forms a pressing surface 26a. Moreover, it is preferable that the pressing part 26 of the crimping member 24 includes a material having an appropriate resilience. This is because by providing a repulsive material, the film 1 can be well adhered and sufficiently pressed. As such a repulsive material, a thick fabric or the like can be used, but an elastic material is preferably used. This is because the elastic material adheres well to the film 1 and can be easily elastically deformed so as to follow the curved surface and irregularities of the surface shape of the adherend H. Here, examples of the elastic material include foams such as urethane foam and rubber foam. The elastic material preferably constitutes the surface layer of the pressing portion 26, but the entire pressing portion 26 may be formed of an elastic material.

As shown in FIG. 3, when the crimping member 24 is a squeegee-like body, it is preferable to include a pressing portion 26 that includes an elastic material and a base portion 28 that supports the upper end side (the opposite side of the pressing surface 26 a). In this way, movement and deformation of the crimping member 24 can be easily controlled via the base 28. In addition, the base part 28 can be made to reach | attain the part close | similar to the press surface 26a of the press part 26 in order to provide moderate flexibility and rigidity in the press surface 26a.
(Bent part)
It is preferable that the crimping member 24 includes a bent portion 30 that allows one or more crimping members 24 to be bent along the sticking width. By providing the bent portion 30, the pressure-bonding member 24 can be greatly deformed in the direction along the sticking width to cause the pressing surface 26 a to follow the surface of the adherend H. An appropriate number of the bent portions 30 can be provided according to the shape of the surface of the adherend H. In this case, when the pressing portion 26 includes an elastic material, various bending forms realized by the bending portion 30 can be easily realized on the pressing surface by elastic deformation of the elastic material.

  The bent portion 30 may be in any form as long as the pressing portion 26 can be deformed, but a part of a support body (rigid portion) such as a base portion and a rotating shaft that movably supports the crimping member 24 can be bent. Thus, the crimping member 24 supported by such a support can be bent. In order to make such a support body bendable, it is only necessary that the support can be bent mechanically, or can be deformed by stress concentration. In order to concentrate the stress, for example, the bending portion of the support is made to be a weak portion, a flexible portion (elastic deformation portion), or a discontinuous portion (the bending range may be connected so that the bending range can be regulated to some extent). it can.

For example, in the squeegee-shaped crimping member 24 shown in FIG. 3, the base portion 28 is formed by the base portions 28 a and 28 b, and a portion where the both are swingably connected is defined as a bent portion 30. The connecting structure has a shape capable of restricting the swinging of the base portions 28a and 28b, here, the two are combined to form a substantially C-shaped guide hole 32, and the connecting member for connecting the base portions 28a and 28b to the guide hole 32. The end of 34 is fixed to be slidable. According to such a connection structure, it is possible to easily construct a bent form in which the bent portion 30 is the apex and the base portions 28a and 28b are inclined downward.
(Crimping member guide part)
The crimping member guide portion 44 holds the crimping member 24 so as to be movable along a locus along the surface of the adherend. For this reason, the crimping member guide portion 44 includes a crimping member moving guide (hereinafter simply referred to as a moving guide) 46 for moving the crimping member 24 along the locus. By providing such a moving guide 46, even if the surface shape of the adherend H has a curved surface shape along the moving direction of the crimping member 24, the crimping member 24 is reliably moved along the shape. Can be made. The movement guide 46 may be provided so as to move the crimping member 24 along a moving direction, and the mechanism for guiding the movement of the crimping member 24 is not particularly limited. It is possible to use a rail that can be engaged with at least a part of 24 (preferably a support such as the base 28) and can be guided along a predetermined locus (the guide may be groove-shaped). Such a guide mechanism can be provided in an appropriate frame, can be provided in a part of the film support portion 4, or can be provided as a unit separate from the film support portion 4. The movement guide 46 is preferably provided at both end portions along at least the attachment width. The form of engagement between the base 28 and the rail is not particularly limited. When the crimping member 24 is provided with a base portion at the top along the sticking width direction like a squeegee-like body, a guide engagement portion such as a hole is formed in the base portion 28 and the guide engagement portion is engaged. A possible rail may be provided.

  When the surface shape of the adherend H changes not only in the moving direction of the pressure bonding member 24 but also in the bonding width direction, the pressure bonding member 24 is moved in the bonding width direction as the pressure bonding member 24 moves. A crimp member guide (hereinafter simply referred to as a deformation guide) 48 to be deformed is preferably provided. In particular, it is preferable when the crimping member 24 is deformed with the above-described bent portion 30. The deformation guide 48 includes a plurality of deformation guides 48 in a portion having a change in the surface shape in the sticking width direction (in other words, in the vicinity of the bent portion 30), so that the crimp member 24 can be easily changed in shape on the surface of the adherend H. Can be followed. Each deformation guide 48 includes a guide portion that follows the surface shape of the adherend H along the moving direction of the crimping member 24 at each forming position. Accordingly, the deformation guide 48 also functions as the movement guide 46 because it guides the movement of the crimping member 24 along the movement direction at the same time.

  For example, as shown in FIGS. 2 and 3, the crimping member guide portion 44 includes movement guides 46 a and 46 b corresponding to both ends of the crimping member 24, and a portion (crimping member having a large change in the surface shape of the adherend H. Deformation guides 48a and 48b are provided on the opposite sides of the 24 bent portions 30. As shown in FIG. 4, the movement guides 46a and 46b and the deformation guides 48a and 48b constitute a locus along the surface shape at the guide position.

  In order to deal with these guides, the squeegee-shaped crimp member 24 shown in FIG. 3 includes guide engaging portions 34a to 34d at both ends of the base portion 28a and both ends of the base portion 28b, respectively. The guide engaging portions 34a to 34d communicate with the moving guides 46a and 46b and the deformation guides 48a and 48b provided in the crimping member guide portion 44, respectively. It is formed in a substantially U-shape including standby engaging portions 38a to 38d through which guides and the like can be inserted. The crimping engagement portions 36a to 36d are portions for engaging the movement guides 46a and 46b and the deformation guides 48a and 48b when the crimping portion 26 of the crimping member 24 is moved with respect to the adherend H, and for standby. The engaging portions 38a to 38d are used when the film 1 is set on the film support portion 4 and the pressure-bonding member 24 set on the pressure-bonding member guide portion 44 is kept on standby without contacting the surface of the adherend H. It is a part to be joined, and is an engaging part for keeping the crimping member 24 away from the adherend surface rather than when the crimping member 24 is moved.

The pressure-bonding member guide portion 44 is used for the pressure-bonding member 24 to press the film 1 supported close to the surface of the adherend H so that the adhesive surface faces the surface of the adherend H toward the adherend H. It is preferable that it is fixed to the film support 4 by an appropriate fixing means. The fixing means is not particularly limited, but those skilled in the art can very easily adopt and implement appropriate means to fix both in a fixed positional relationship.
(Frame)
The bonding apparatus 2 in which the film support portion 4 on which the film 1 is supported and the pressure bonding member guide portion 44 including the pressure bonding member 24 are fixed in a predetermined positional relationship is further applied to a predetermined surface of the adherend H. Need to be set. For this purpose, a gantry 200 that supports the sticking device 2 in a movable manner can be used. The gantry 200 includes, for example, moving means such as casters and a bracket portion to which the sticking device 2 can be fixed. Furthermore, the gantry 200 can also include support means that can float and support the gantry in a state where the moving means such as casters are separated from the floor surface. In the form illustrated in FIG. 5, the moving means 202, the bracket portion 204, and the supporting means 206 are provided.
(Attaching film)
As the film 1 stuck to the adherend H by the sticking apparatus 2 of the present invention, for example, a film in the form of a film laminate 100 shown in FIG. 6 can be used. The laminate 100 is adhered to the surface of the film 1 (also referred to as a film main body in the laminate) that is finally attached to the surface of the adherend H, and to the adhesive surface that is the back surface of the surface protective layer 102. An adhesive surface protective layer (peeling layer) 103 that protects the surface and is peeled off before sticking is provided. The surface protective layer 102 includes an upper extension portion 104 and a lower extension portion 106 that are formed to extend from the end of the film 1 at least at the upper and lower ends of the film 1. In addition, engagement holes 114 and 116 are provided as fixing means that can be fixed to the film support 4. Preferably, the surface protective layer 102 includes side extension portions 108 and 110 that are formed to extend also on the side of the film 1, and the extension portion 108 is engaged as a fixing means that can be fixed to the film support portion 4. Combination holes 118 and 120 may be provided.

  The extension portions 104, 106, 108, and 110 have extension portions provided with fixing means on the inner side of the fixing means provided on the extension portions (the outer side than the peripheral edge of the film 1). Separating weakened portions 134, 136, 138, and 140 that enable the portions to be easily separated are provided. The weakening portions 134, 136, 138, and 140 for separation can be easily separated from the surface protective layer at any portion in any form. For example, intermittent holes such as perforations are provided. be able to.

In the present embodiment, in the laminate 100, the extending portions are formed on the upper and lower sides and the left and right sides of the film body. However, the present invention is not limited to this, and at least extends to each of a pair of opposing sides of the film body. The part should just be formed, and the pair of sides may be a pair of sides opposed to the top and bottom of the film 1 or a pair of sides opposed to the left and right.
(Manufacturing method of a sticking body)
Next, the manufacturing method of the sticking body using the sticking apparatus of this invention is demonstrated.

  First, the laminated body 100 is set with respect to the film support part 4 previously set to the bracket part 204 of the mount frame 200. FIG. The engaging hole 114 above the laminated body 100 is locked to the pin-shaped convex portion 8 above the film supporting portion, and the side hole portions 1118 and 120 are pinned to the pin-shaped convex portion 12 lateral to the film supporting portion. , 14. Further, the engaging hole 116 below the film 1 is locked to the pin-like convex part 10 below the film support part. By supporting the upper and lower ends of the film 1, even if the surface shape of the adherend H is convex in the vertical direction, the adhesive surface of the film 1 can be held close to each other without contacting the surface of the adherend H. At the same time, by supporting both sides of the film 1, even if the surface shape of the adherend H is convex in the sticking width direction, the adhesive surface of the film 1 may be brought close to the surface of the adherend H. It can be made to face without contacting.

  The pressure-bonding member guide portion 44 set by the pressure-bonding member 24 being engaged and set at the standby engaging portions 38 a to 38 d is fixed to the film support portion 4 to set up the sticking device 2. Next, the adhesive surface protective layer 103 on the back surface of the film 1 is peeled to expose the adhesive surface. Then, after fixing the sticking apparatus 2, it sets to the predetermined position of the to-be-adhered body H surface with a mount. Since the surface of the film support 4 on the adherend H side is formed in advance along the surface shape of the adherend H, the sticking device 2 can be reliably set at a predetermined position. It is preferable that the crimping member 24 is set in a standby state at a substantially central portion of the moving range. The film 1 can be adhered to the adherend H accurately and by avoiding adhesion failure by first performing the crimping of the crimping member 24 upward and then downward.

  In this state, the engagement part between the crimping member 24 and the movement guide is moved from the standby engagement parts 38a to 38d to the crimping engagement part 36a to 36d, and the film is formed at the central part in the moving direction of the crimping member 24. 1 is pressed against the surface of the adherend H and brought into contact therewith. Then, the base 28 of the crimping member 24 is manually operated to move the crimping member 24 upward along the movement guides 46a and 46b and the deformation guides 48a and 48b. The crimping member 24 is guided by each of the movement guides 46a and 46b and the deformation guides 48a and 48b and moves upward along a movement direction along a predetermined locus, and at the same time, the form in the sticking width direction is controlled, and the pressing surface of the pressing portion 26 26a always follows the surface shape of the adherend H. Deformation in the sticking width direction of the crimping member 24 controlled by the movement guides 46a and 46b and the deformation guides 48a and 48b is made possible by the bending portion 30 formed in the crimping member 24 and the elastically deformable pressing portion 26. . In FIG. 7, the crimping | compression-bonding member 24 shows the deformation | transformation state in the sticking width direction shown in several positions of a movement range by the movement guides 46a and 46b and the deformation | transformation guides 48a and 48b. By such deformation of the pressure-bonding member 24 in the sticking width direction, in particular, the pressing portion 26, it is possible to faithfully follow the surface of the adherend H in the sticking width direction. By achieving such movement and deformation at the same time, the film 1 is pressed and brought into contact with the surface of the adherend H by the pressure-bonding member 24 with a uniform pressing force at all times in the sticking width and moving direction. Will be affixed to. As a result, poor sticking such as wrinkles, kinks and air bites can be effectively avoided.

  The pressure bonding member 24 reaches the upper end of the film 1, and the film 1 is adhered to the surface of the adherend H in a state where the surface is covered with the surface protective layer 102. At substantially the same time or around this time, the vicinity of the separation weakening portion 134 of the extension portion 104 on the upper end side of the film 1 is pressed, so that the distal end side of the extension portion 104 supported by the film support portion 4 It isolate | separates in the weak part 134 for isolation | separation. In this way, by using the film laminate 100, it is possible to release the support state of the film with respect to the film support portion 4 for positioning while performing the sticking operation. For this reason, after the sticking operation, it is necessary to separately release the support state, that is, to engage the engagement hole 114 and the like in the extended portion 104 and the pin-like convex portion 8 of the film support portion 4. Absent. In addition, since the surface protective layer 102 includes a fixing means for the film support portion 4, it is sufficient for the film laminate 100 to have only the film 1 corresponding to the portion where the film is to be attached.

  Next, the crimping member 24 is moved in the opposite direction. When the crimping member 24 reaches the side locking portion of the film 1, the distal ends of the lateral extension portions 108 and 110 are separated at the weakened portions 138 and 140 for separation. Subsequently, when the pressure-bonding member 24 is moved downward to reach the lower end, the entire film body 1 is adhered to the surface of the adherend H, and extends at the lower end side of the film almost simultaneously or before and after. By pressing the vicinity of the separation weak part 136 of the part 106, the distal end side of the extension part 106 supported by the film support part 4 is separated by the separation weak part 136.

  Although the sticking process can be completed as described above, an appropriate pressure can be applied to the film 1 by repeating the vertical movement of the crimping member 24. When the sticking step is finished, the engagement parts of the guide engagement portions 34a to 34d of the crimping member 24 are moved from the crimping engagement parts 36a to 36d to the standby engagement parts 38a to 38d, and the crimping member 24 is moved. It separates from the adherend H and enters a standby state.

  Thereafter, the fixed state of the gantry 200 on the floor surface is released and separated from the adherend H, and the distal ends of the extension portions 104, 106, and 108 remaining on the film support portion 4 of the sticking device 2 are separated. Then, the surface protective layer 102 of the film 1 adhered to the adherend H is extended from the peripheral edge of the film 1 and is held by gripping one of the base portions of the extended portions 104, 106, and 108. Peel from the main body 1. Since any one of the remaining extended portions 104 and the like can be gripped, the surface protective layer 102 can be easily separated from the film 1.

  According to the sticking apparatus of the present invention, the positioning and setting of the film 1 with respect to the adherend H is performed by fixing the film 1 with respect to the film support part 4 at the upper and lower positions and the sticking apparatus 2 on which the film support part 4 is set. By positioning on the adherend H, the film 1 is accurately positioned with respect to the adherend H. In particular, when the film 1 is fixed to the film support part 4 also on the side thereof, even if the surface of the adherend H is convex along the sticking width direction, Since it can be made to oppose and adjoin so that an adhesion surface may not contact, the contact of an adhesion surface can be avoided and the film 1 can be set to the to-be-adhered body H easily. Further, in the set state of the film 1, the film 1 is brought into contact with the surface of the adherend H by moving the pressure-bonding member 24 from the standby engagement portions 38 a to 38 d to the pressure-bonding engagement portions 36 a to 36 d. Since the positioning can be confirmed, the first sticking operation of the film 1 can be performed accurately.

  Further, in the sticking step, the movement of the crimping member 24 is merely moved along the movement guides 46a and 46b and the deformation guides 48a and 48b. Air biting can be effectively avoided. Therefore, a film sticking body having a good appearance can be produced with high production efficiency. In particular, even if the pressure-bonding member 24 has a bent portion 30 and can be deformed in the sticking width direction, and has a deformation guide, such a surface can be obtained even if it has a curved surface or an uneven shape in the sticking width direction. Regardless of the shape, it is possible to apply sufficient pressure to the film 1 to deform the pressing portion 26 and make the pressing surface 27 adhere to follow the surface shape, and it is effective for insufficient pressing force, wrinkles and air biting at the site. Can be suppressed.

  From the above, according to the present sticking apparatus and the method for manufacturing the sticking body, the film 1 can be set and positioned on the surface of the adherend H without skill, and the film 1 can be sufficiently and reliably attached. Since it can press on the surface of the adherend H, sticking failure can be easily suppressed.

  In addition, according to the crimping member guide portion 44 of the sticking apparatus 2, the crimping member 24 is attached to the film 1 or the adherend H in order to have a standby engagement portion even when the crimping member 24 is held. Can wait for the surface. Since the pressure-bonding member guide portion 44 holding the pressure-bonding member 24 can be set in advance with respect to the film support portion 4, the work process can be simplified. Moreover, since this sticking apparatus 2 is equipped with the standby engaging part on the crimping member 24 side, the form of the movement guide can be simplified.

In the sticking apparatus 2 of this embodiment, the crimping member guide portion 44 is provided in a separate unit from the film support portion 4, but the present invention is not limited to this, and as will be described below, the crimping member guide portion 44. Can be provided partly on the film support and the rest on another unit.
(Second form)
Next, the other form of the sticking apparatus of this invention is demonstrated. About the sticking apparatus 62 of this form, it demonstrates mainly about a different structure from the sticking apparatus 2 of a 1st form.

The frame 66 is provided.

  As shown in FIG. 10A, the pressure-bonding member 74 of the present embodiment is a roller-like body that can rotate and move on the surface of the adherend H. The roller-like body is a cylindrical body or a columnar body having a length corresponding to the sticking width and having a circular cross section, and a pressing portion 76 whose peripheral surface is the pressing surface 76a is formed. A central shaft 78 that rotatably supports 76 may be provided. In the present embodiment, the pressing portion 76 is itself formed of a cylindrical body made of an elastic material. Further, the crimping member 74 has a bent portion 80 at one place in the sticking width direction. In this embodiment, the bent part 80 is formed in a discontinuous part in which the central shaft 78 is separated to such an extent that the pressing portion 76 can be elastically deformed at the bent part 80. That is, the center axis 78 is divided into center axes 78a and 78b with the bent portion 80 interposed therebetween.

  The central shaft 78 is preferably configured to rotate the pressing portion 76 without rotating together with the pressing portion 76. For this purpose, it is preferable to provide a cylindrical body 79 through which the central shafts 78a and 78b are inserted, and to provide a pressing portion 76 on the surface of the cylindrical body 79. By providing the cylindrical body 79, it is possible to easily achieve both rotational movement and deformation of the crimping member 74. Further, by providing the cylindrical body 79, the central shaft 78 can be made small, the load amount required at the time of work can be reduced, and the crimping member 74 itself can be made compact.

  As shown in FIGS. 8 to 10, the crimping member guide portion 84 can move the crimping member 74 along the surface of the adherend H by engaging the rotation shafts 78 a and 78 b protruding from both ends of the crimping member 74. Crimp member guides (moving guides) 86a and 86b are provided. As shown in FIG. 10B, in this embodiment, the movement guides 86a and 86b are frames having slide grooves that can engage with the rotation shafts 78a and 78b and have a locus along the surface of the adherend H, respectively. A side frame of the film support 64 is formed. Note that the movement guides 86a and 86b are respectively provided in part of the slide groove, with the rotating shafts 78a and 78b being separated from the adherend H and holding the crimping member 64 more than during the crimping. 87b is provided at the center of the movement trajectory of the movement guides 86a and 86b, respectively.

  As shown in FIG. 8B, the crimping member guide portion 84 transforms the crimping member guide (deformation guide) 90 for deforming the crimping member 74 in the sticking width direction separately from the movement guides 86a and 86b. A guide unit 88 is provided. In this embodiment, since the crimping member 74 is a roller-like body, the moving direction can be regulated by the rotation shafts 78a and 78b that are protruded to both ends of the crimping member 74 in the pasting width direction. In order to deform | transform along this, it is necessary to take the form which presses the crimping | compression-bonding member 74 toward the to-be-adhered body H. FIG. The deformation guide unit 88 includes a deformation guide 90 that directly presses the rotating crimping member 74 and a frame 92 that supports the deformation guide 90. As with the sticking device 2, the deformation guide 90 is preferably provided with a plurality of deformation guides 90 along the sticking width direction at a portion where the shape changes in the sticking width direction (formation part of the bent part 80). In addition, in order to suppress the lifting of the crimping member 74, it is preferable to appropriately include the deformation guide 90 even in a portion where the shape change is small. In this embodiment, two deformation guides 90c and 90d are provided in the vicinity of the bent portion 80, and other deformation guides 90a and 90b are provided. These deformation guides 90a to 90d are formed as guides that extend in the movement direction and have a trajectory along the surface shape of the adherend H along the movement direction at the respective formation sites. Function. The deformation guides 90a, 90b, 90c, and 90d of this embodiment are each formed into a pipe-like body having a circular cross section having a locus along the moving direction as shown in FIG. The frame 92 that supports the deformation guides 90 a to 90 d is formed so as to be fixed to the film support portion 64.

  Next, a method for manufacturing an adhesive body using such an adhesive device 62 will be described focusing on differences from the adhesive method using the adhesive device 2. When the sticking device 62 is used, after the film 1 is set in the same manner as the sticking device 2 on the film support 64 fixed to the gantry 200 in advance, the crimping member 74 is moved to the guide 86a of the crimping member guide portion 84. 86b, and the deformation guide unit 88 is set on the film support 64. After the sticking device 62 is set up on the gantry 200 in this manner, the gantry 200 is positioned with respect to the place where the film 1 of the adherend H is to be stuck, and then fixed to the floor surface.

  Thereafter, the engagement of the rotary shafts 78a and 78b of the crimping member 74 at the standby engaging portions 87a and 87b is released and engaged with the slide grooves of the movement guides 86a and 86b. The crimping member 74 is rotated and moved above the adherend H by operating the slide groove 78b by hand. As already described, when the crimping member 74 reaches the end of the movement range, the distal end side of the extension part 104 is separated at the separating weak part 134 in the extension part 104 on the upper side of the film 1. The upper side is attached to the surface of the adherend H. Thereafter, by moving the crimping member 74 to the lower moving end, the tip end side of the extending portion on the lower side of the film 1 is separated and the lower side of the film 1 is attached to the adherend H, and thereafter By appropriately moving the crimping member 74 in the vertical direction as necessary, the adhering step is completed. After that, it is the same as that in the sticking apparatus 2. In FIG. 12, the crimping | compression-bonding member 74 shows the deformation | transformation state in the sticking width direction shown in several positions of a movement range by the movement guides 86a and 86b and the deformation | transformation guides 90a-90d.

  According to the sticking device 62 and the sticking body manufacturing method of the present embodiment, the film 1 is pressed against the surface of the adherend H by the rotating roller-like body, and the pressure-bonding member 74 is smoothly and well adhered. Can be moved. For this reason, the film 1 can be more easily stuck.

  In the sticking device 62 of the second embodiment, moving guides 86a and 86b for engaging and supporting the rotating shafts 78a and 78b of the pressure bonding member 74 of the roller-like body and the pressing portion 76 are used as the pressure bonding member guide. The deformation guides 90a to 90d for pressing to H are provided and provided in another unit, but the present invention is not limited to this. The movement guides 86a and 86b and the deformation guides 90a to 90d can be collectively provided in one unit (for example, the movement guide is provided in a part of the guide unit 88).
