[0094] Hereinafter, a sheet fabrication apparatus according to one aspect of the present invention will be described with reference to the accompanying drawings. Furthermore, in the description with reference to the drawings, the sheet fabrication apparatus is placed on a mounting surface. Figure 1 In the text, arrows are used to represent the top, bottom, left, right, front, and back of the object, and the descriptions of the top, bottom, left, right, front, and back are based on these arrows.

[0095] Figure 1 This is a perspective view of a sheet fabrication apparatus 1 according to one aspect of the present invention, viewed from the front side. Figure 2This is a perspective view of the sheet fabrication device 1 viewed from the rear side.

[0096] Figure 1 and Figure 2 The sheet fabrication apparatus 1 shown is used to fabricate a single laminated sheet 20 by laminating, for example, three sheet components (first sheet component 21, second sheet component 22, and third sheet component 23). Figure 4 , Figure 5 The sheet fabrication apparatus 1 is used by placing the lower end 5d of the apparatus body 5 on a horizontal mounting surface 60. The apparatus body 5 has a holding part 10, which, in the mounted state, opens at the upper end 5u of the apparatus body 5 to hold three sheet components 21, 22, and 23 respectively.

[0097] Additionally, a limiting part 18 is provided on the main body 5 of the device. This limiting part 18 can be operated to allow the held sheet members 21, 22, and 23 to fall to the bonding part 15 below them (see reference). Figure 3 As will be described later, the limiting part 18 is a plate-shaped component, and as part of it, an exposed part is provided that extends to the left and right from the outside 5s of the device body 5, and operating parts 18a and 18b are provided thereon. That is, the limiting part 18 is configured to be able to move in the left and right directions relative to the device body 5 as will be described later, and to be operated by pressing in the operating parts 18a and 18b.

[0098] A generally cylindrical bonding operation part 8 capable of rotation is provided on the lower side of the limiting part 18. This bonding operation part 8 and the main roller 15a (described later) of the bonding part 15 (see reference) Figure 3 The three sheet components supplied to the bonding section 15 are connected and rotated in a specified direction (clockwise in the figure). Through this rotation operation, the three sheet components are fed downward while being pressed and bonded in their thickness direction.

[0099] A front opening 9a is provided on the front side of the main body 5, through which the main roller 15a constituting the bonding part 15 can be seen. Furthermore, a wall surface with a forward-curving inclination is provided below the front opening 9a (see reference). Figure 3 The outlet 6 is used to discharge the bonded sheet 20 forward. Additionally, as... Figure 2 As shown, a back opening 9b is provided on the back side of the main body 5, through which the driven roller 15b constituting the bonding part 15 can be seen. In addition, the length (L9) of the back opening 9b and the front opening 9a in the left-right direction is configured to be the length of the entire area in the width direction of the outer peripheral surfaces 15as and 15bs of the two rollers 15a and 15b that can be seen, and is configured to be larger than the width of each sheet member 21, 22, and 23.

[0100] Figure 3 It is along Figure 1 A vertical sectional view of the portion along line AA.

[0101] In the retaining part 10, such as Figure 3 As shown, three sheet components 21, 22, and 23 are held as a part of the device, protruding upwards. This sheet holding structure consists of guide portions 11a, 12a, and 13a and a restraining portion 18. The guide portions 11a, 12a, and 13a guide the left and right ends 21e, 22e, and 23e (see reference 18) of the sheet components when they are placed. Figure 5 The limiting part 18 guides the top edges 21t, 22t, and 23t on the lower side of the sheet (refer to...). Figure 5 Part of the sheet engages to restrict its descent. Sheet ends 21e, 22e, and 23e are portions excluding the adhesive surfaces.

[0102] The first holding portion 11 of the first sheet member 21 is positioned directly above the closest fitting portion 15. The second holding portion 12 of the second sheet member 22 is positioned in front of the first holding portion 11 and is tilted at a first tilt angle θ1 relative to the vertical direction, so that the second sheet member 22 falls toward the fitting portion 15. The third holding portion 13 of the third sheet member 23 is positioned in front of the second holding portion 12 and is tilted at a second tilt angle θ2 greater than the first tilt angle θ1, so that the third sheet member 23 falls toward the fitting portion 15.

[0103] Thus, the holding part 10 is positioned with the first holding part 11 holding the first sheet member 21 in a vertical position as the basis, and the tilt angle relative to the vertical direction increases as the arrangement order from the first holding part 11 is later, such as the second and third.

[0104] The bonding section 15, located below the holding section 10, is composed of a main roller 15a and a driven roller 15b extending in the left-right direction. The main roller 15a is configured to be connected to the bonding operation section 8 and driven to rotate. The driven roller 15b, which is arranged to face the outer peripheral surface 15as of the main roller 15a and contact its outer peripheral surface 15bs, is driven to rotate by the driving force of the main roller 15a when a sheet member is sandwiched between it and the main roller 15a.

[0105] Figure 4 This is a perspective view of the holding part 10 of the main body 5 of the device viewed from above.

[0106] The retaining part 10, when viewed from above, has an opening that is generally rectangular in shape, and is arranged in the order of first retaining part 11, second retaining part 12, and third retaining part 13 from the rear side of the device. As described above, each retaining part 11, 12, and 13 is configured to retain the first sheet member 21, the second sheet member 22, and the third sheet member 23 respectively using guide parts 11a, 12a, and 13a. The guide parts 11a, 12a, and 13a are formed into grooves c by the front and rear paired wall surfaces of the left and right end sides of the sheet member. That is, the retaining part 10, which guides each sheet member, only retains and guides the sheet ends 21e, 22e, and 23e, and is an open structure without wall surface structures opposite to the front and back surfaces of the sheet members.

[0107] Furthermore, a groove 19 is provided between the second retaining part 12 and the third retaining part 13. This groove 19 is a groove for mounting the retaining plate 40. Figure 3 As shown, the retaining plate 40 is installed by fitting into the groove 19 in a manner that extends upward toward the device body 5, thereby holding the second sheet member 22 in a way that prevents it from falling over.

[0108] Figure 5 It is a three-dimensional view of each sheet component before bonding.

[0109] In this method, such as Figure 5 As shown, the first sheet member 21, the second sheet member 22, and the third sheet member are placed in the aforementioned holding portion 10 with a predetermined orientation. Then, after placing the sheet members, the operation of the restricting portion 18 and the bonding operation portion 8 are performed to produce the bonding sheet 20.

[0110] The first sheet member 21 is thicker than the other sheet members and functions as a backing paper. An adhesive layer 21b is provided on one side of the first sheet member 21 (the upper side in the figure). This adhesive layer 21b is not provided at the sheet end 21e on the outer periphery of the first sheet member 21. The sheet end 21e is guided by the guide portion 11a, thereby allowing the first sheet member 21 to move smoothly without being adhered to the guide portion.

[0111] The second sheet member 22 can be made of, for example, a sheet or photograph depicting a specified character. The second sheet member 22 is configured such that, for example, a pattern is depicted on the surface except for the sheet end 22e, and there is no adhesive layer on either the surface or the back.

[0112] The third sheet member 23 is a translucent sheet with an adhesive layer 23b on one side (the lower back side in the figure), forming a structure in which the pattern of the second sheet member 22 is visible. Additionally, the third sheet member 23 may have a decorative pattern that decorates the pattern of the second sheet member 22, except for the transparent portion. Furthermore, the adhesive layer 23b is not provided at the sheet end 23e on the outer periphery of the third sheet member 23. This sheet end 23e is guided by the guide portion 13a, allowing the third sheet member 23 to move smoothly without being adhered to the guide portion.

[0113] Figure 6 It is along Figure 5 The BB line section represents a cross-sectional view of the sheet material in its bonded state.

[0114] 20-inch laminated sheet Figure 6 As shown, the second sheet member 22 is bonded while being sandwiched between the adhesive layer 21b of the first sheet member 21 and the adhesive layer 23b of the third sheet member 23. Furthermore, the sheet ends 21e, 22e, and 23e form unbonded sheet ends 20e. In this bonded sheet 20, the unbonded sheet ends 20e are cut off after bonding to complete the bonded sheet 20.

[0115] Figure 7 This is an enlarged three-dimensional cross-sectional view of the bearing portion of the roller pair in the bonding section 15.

[0116] The bonding section 15 is configured such that the outer peripheral surfaces 15as and 15bs of the main roller 15a and driven roller 15b are positioned opposite each other in a manner that allows them to contact. Furthermore, the rotation shaft 15af of the main roller 15a, which is driven by rotation, is supported by a circular bearing portion 5j and can rotate without shifting its rotation center. The rotation shaft 15bf of the driven roller 15b is supported by an elongated bearing portion 5g with an elongated hole shape and can rotate. The elongated hole shape of the bearing portion 5g is oriented downwards towards the main roller 15a. That is, the rotation shaft 15bf of the driven roller 15b rotates while being moved towards the main roller 15a by the force exerted by the rotation of the rollers during bonding. This allows for reliable bonding of sheet components.

[0117] Figure 8 It is a perspective view with a horizontal cross-section near the location of the limiting part 18.

[0118] The limiting part 18 is configured to form the bottom of the retaining part 10, such as Figure 8As shown, the plate member is constructed as a single unit. The limiting part 18 is configured to extend in the left-right direction along the device body 5 and be able to slide in the left-right direction. In addition, the limiting part 18 has exposed parts protruding from the outside 5s of the device body 5 at its left and right ends. Furthermore, the exposed parts are configured as operating parts 18a and 18b that can be pressed left and right to make the limiting part 18 slide as a whole. In addition, the limiting part 18 has a front protrusion 18d protruding forward and a rear protrusion 18e protruding rearward, and the two protrusions 18d and 18e are slidably supported on the sliding support surface 5i of the device body 5.

[0119] Next, the operation of the limiting part 18 will be explained.

[0120] Figure 9 This is an explanatory diagram showing the positional relationship between the limiting part 18, which is used to explain the operation of the limiting part 18, and each sheet component 21, 22, 23.

[0121] When the sheet components are inserted into the holding part 10, the limiting positions P1, P2, and P3, formed by the three stepped end edges provided on the left side of the figure, limit their position by holding the lower end edges of each sheet component 21, 22, and 23 to prevent them from falling. In this holding state, a portion of the first limiting position P1 contacts the top edge 21t of the first sheet component 21 with a contact range L1, thus limiting its position. A portion of the second limiting position P2 contacts the top edge 22t of the second sheet component 22 with a contact range L2, thus limiting its position. Furthermore, a portion of the third limiting position P3 contacts the top edge 23t of the third sheet component 23 with a contact range L3, thus limiting its position.

[0122] The restriction state of the restriction section 18 is released, for example, by pressing in the operating section 18a. The operation of the operating section 18a controls the movement of each sheet member 21, 22, 23 in the direction of descent (i.e., the direction of descent). Figure 9 The limiting part 18 moves to the left in the direction X1 along the left-right direction (first direction (X)) of the top edges 21t, 22t, 23t of the sheet members 21, 22, 23. That is, by moving the limiting part 18 to the left in the direction X1, initially, the limiting position P1 deviates to the left relative to the left end of the first sheet member 21 in the figure, and the first sheet member 21 begins to fall. Then, the limiting position P2 deviates to the left relative to the left end of the second sheet member 22 in the figure, and the second sheet member 22 begins to fall. Then, the limiting position P3 deviates to the left relative to the left end of the third sheet member 23 in the figure, and the third sheet member 23 begins to fall.

[0123] Thus, the release of restrictions occurs in the order of the first sheet member 21, the second sheet member 22, and the third sheet member 23, with each sheet member 21, 22, and 23 arriving at the bonding portion 15 sequentially, starting with the first sheet member 21. This ensures that the second sheet member 22 and the third sheet member 23 are accurately supplied to their bonding positions on the first sheet member 21, which is supplied vertically to the bonding portion 15. Then, by rotating the bonding operation unit 8, the bonding sheet 20 bonded by the bonding portion 15 is discharged from the discharge port 6.

[0124] In addition, the limiting part 18 moves to the right (X2) by pressing the operating part 18b on the left side, thereby returning to the position where each sheet component 21, 22, 23 can be held.

[0125] (Modified example)

[0126] Figure 8 and Figure 9 The limiting portion 18 shown is configured to extend along the left-right direction of the device body 5. However, in this invention, the structure is not limited to this; for example, it may also extend in the front-back direction of the device body 5, i.e., the second direction (Y) (see reference). Figure 9 The structure allows for sliding movement. In this structure, the limiting part 18, which moves in the forward and backward direction, is configured to have an operating part exposed in the forward and backward direction from the device body 5. Moreover, the operation of this operating part is a structure that moves forward and backward (in the forward direction (Y1) and the backward direction (Y2)). In addition, in this structure, it can be configured such that when the edge of the lower edge of each sheet member 21, 22, 23 held in the limiting part 18 moves in the forward direction (Y1) of the device body 5, it begins to fall in the order of the first sheet member 21, the second sheet member 22, and the third sheet member 23.

[0127] As described above, the sheet manufacturing apparatus 1 of this method is equipped with a limiting part 18 that can control the timing of the movement of multiple sheet components 21, 22, 23 toward the bonding part 15 in a manner that allows them to be stacked together, thereby enabling sheet supply that is suitable for the bonding sequence of the multiple sheet components 21, 22, 23.

[0128] In the sheet manufacturing apparatus 1 of this method, by providing a holding part 10 that holds sheet components (first sheet component 21, second sheet component 22, and third sheet component 23) by type, the individual supply time of each type of sheet component can be easily set.

[0129] In the sheet manufacturing apparatus 1 of this method, the first sheet member 21, which is configured to have the largest thickness of the backing paper in the finished sheet (laminated sheet 20) after lamination, arrives at the lamination part 15 first, so that the arrangement and positioning of the other sheet members supplied to the first sheet member 21 can be accurate.

[0130] In the sheet manufacturing apparatus 1 of this method, the first holding part 11, which houses the first sheet member 21 in the vertical direction, is positioned directly above the bonding part 15, and the tilt angles of the other holding parts relative to the first holding part 11 increase in descending order of stacking, thereby enabling precise supply to the bonding part 15.

[0131] In the sheet manufacturing apparatus 1 of this method, the movement of each sheet component 21, 22, 23 toward the bonding portion 15 is a free fall, thereby eliminating the need for a driving component or a force-applying component for the movement of the sheet components, which simplifies the structure of the apparatus.

[0132] In the sheet manufacturing apparatus 1 of this method, by placing the first sheet member 21 directly above the gap between a pair of rollers (adhesion portion 15), the first sheet member 21 can be positioned at the position closest to the adhesion portion 15.

[0133] In the sheet manufacturing apparatus 1 of this method, the holding part 10 has guide parts 11a, 12a, and 13a that guide only the sheet ends 21e, 22e, and 23e along the moving direction of the sheet member. Thus, even when the sheet member has an adhesive area, the non-adhesive areas of the sheet ends 21e, 22e, and 23e can be guided, and the sheet can be supplied smoothly.

[0134] In the sheet manufacturing apparatus 1 of this embodiment, the holding part 10 has a groove 19 for mounting a plate (holding plate 40) that can hold the sheet member in a certain position, thereby stabilizing the position of the sheet member in the holding state. In addition, the sheet member can be reliably held even if it protrudes from the holding part 10 by a certain size.

[0135] Furthermore, according to the sheet manufacturing apparatus 1 of this method, the limiting part 18 is configured as a plate member with a contact range L1, L2, L3 (contact length) of a limiting contact part that contacts the top edges 21t, 22t, 23t of the sheet members in the direction of movement of the plurality of sheet members 21, 22, 23 and restricts their movement. The contact range L1, L2, L3 is different for each sheet member, so that the movement time of the sheet members can be different by moving the limiting part 18.

[0136] In the sheet manufacturing apparatus 1 of this method, the limiting part 18 is composed of a plate member with an integral structure that can simultaneously support the top edges 21t, 22t, and 23t of multiple sheet members 21, 22, and 23. Thus, the movement of multiple sheet members 21, 22, and 23 can be limited and controlled by operating only one plate member.

[0137] According to the sheet manufacturing apparatus 1 of this method, the limiting part 18 is configured to move in the intersecting direction of the moving directions of the plurality of sheet members 21, 22, 23. Thus, by moving the limiting part 18 horizontally relative to the lower edge (the upper edge 21t, 22t, 23t of the moving direction) of the sheet member in the free fall direction (movement in the first direction and the second direction), the position restriction of the sheet member can be easily released.

[0138] In the sheet manufacturing apparatus 1 of this method, the limiting part 18 has operating parts 18a and 18b that are partially exposed outside the main body of the sheet manufacturing apparatus 1 for 5 seconds, thereby making it easier to slide the limiting part 18.

[0139] In the sheet manufacturing apparatus 1 of this method, the bonding section 15 is composed of a main roller 15a and a driven roller 15b that bring their outer peripheral surfaces 15as and 15bs together, thereby enabling pressure to be applied to the entire sheet surface of the multiple stacked sheet members 21, 22, 23.

[0140] Furthermore, in the driven roller 15b, which rotates in tandem with the main roller 15a, its rotation shaft 15bf is supported (by the elongated bearing portion 5g) in a manner that allows it to move toward the main roller 15a according to the bonding action. As a result, effective pressing pressure can be generated by the driven roller 15b during the roller rotation of the bonding action of the sheet member.

[0141] In the sheet forming apparatus 1 of this method, the main roller 15a and the driven roller 15b are configured to be visible from the openings (front opening 9a and rear opening 9b) of the sheet forming apparatus 1, thereby allowing access to the blockage of the sheet member through the openings. In addition, by configuring the width of the opening in the roller axis direction to be larger than the width of the sheet member, it is easy to remove the sheet member to the outside when it becomes blocked.

[0142] The present invention has been described above in one aspect, but the invention can be modified appropriately within the scope of its technical concept. For example, in the above aspect, the case of bonding three sheet members has been described; however, the case of using two sheet members is also possible.

[0143] In addition, in the above-described manner, the groove 19 for mounting the retaining plate 40 is provided between the second retaining portion 12 and the third retaining portion 13, but it is not limited to this. For example, it may be provided at a position further forward than the third retaining portion 13.
