  Then, operation | movement of the surface sheet sticking system 1 of this embodiment is demonstrated in detail mainly with reference to FIG. 8 thru | or FIG. In the surface sheet pasting system 1 of the present embodiment, first, the core material 3 that has been cut into a predetermined shape in advance is placed on the core material placement unit 10, and the sheet placement unit 40 has a shape corresponding to the core material 3. The surface sheet 4 cut in advance is placed.

  When the surface sheet pasting system 1 is operated in this state, the sheet adsorbing member storage device 100 replaces the storage tray 101 in which the sheet adsorbing member 90 corresponding to the shape of the surface sheet 4 to be pasted with the corresponding tray driving mechanism 103. To pull out from the storage device body 102. Subsequently, in the sheet conveying device 50, the tip of the articulated robot 52 is moved to the position of the connected portion 93 of the sheet adsorbing member 90 stored in the drawn out storage tray 101, and then the connecting portion at the tip thereof. 55 is connected to the connected portion 93 of the sheet adsorbing member 90, and the sheet adsorbing member 90 is attached to the tip. Then, when the leading end of the sheet conveying apparatus 50 is raised with the sheet adsorbing member 90 attached to the leading end of the sheet conveying measure 50, the sheet adsorbing member 90 is taken out from the storage tray 101 (see FIG. 8). ).

  The sheet conveying apparatus 50 having the sheet adsorbing member 90 attached to the front end and taking out the sheet adsorbing member 90 from the storage tray 101 has the front surface sheet 4 placed on the sheet placing portion 40. After moving upward (see FIG. 9B), the protection portion 91 a of the main body plate 91 is brought into contact with the surface of the topsheet 4. At this time, in the sheet conveying apparatus 50, the surface placed on the surface is obtained by photographing the surface sheet 4 placed on the sheet placing unit 40 and performing a predetermined image analysis with a camera provided at a predetermined position. The shape and orientation of the sheet 4 are confirmed, and the sheet adsorbing member 90 is brought into contact with the orientation corresponding to the orientation of the placed topsheet 4. Specifically, for example, as shown in FIG. 2, by photographing and analyzing the corners P at both ends of the predetermined side of the surface sheet 4, the sheet adsorbing member 90 is placed on the surface sheet 4 placed thereon. Adjust the direction.

  When the surface sheet 4 is not placed on the sheet placement unit 40 by image analysis or when the placed surface sheet 4 is different from the target shape, an alarm is issued and the surface sheet is pasted. System 1 is stopped.

  Further, when the sheet adsorbing member 90 is brought into contact with the top sheet 4, the leading end of the sheet conveying device 50 is provided with a buffer mechanism 53, so that the sheet adsorbing member 90 is attached to the top sheet by the biasing force of the buffer spring 53d. 4, the top sheet 4 can be brought into homogeneous contact with the protective portion 91 a of the main body plate 91, and the main body plate 91 of the sheet adsorbing member 90 is brought into contact with the top sheet 4. Impact can be reduced.

  Then, with the sheet adsorbing member 90 in contact with the topsheet 4, negative pressure is supplied to the fixed-side adsorbing portions 94 and the movable-side adsorbing portions 95 at both ends of the sheet adsorbing member 90 to respectively suck the sucker portions 94a and 95a. The top end of the top sheet 4 is adsorbed by At this time, the suction cups 94a and 95a are pressed against the topsheet 4 by pressing the sheet suction member 90 to the topsheet 4 side via the buffer mechanism 53 by the articulated robot 52 of the sheet transport device 50. Adsorb firmly. Next, the cylinder rod 95e is moved forward by the movable cylinder 95f of the movable-side suction unit 95, the top sheet 4 is pulled to a tight state, and the sheet suction member 90 is lifted by the sheet conveying device 50, and the sheet placement unit 40 is moved. Then, the top sheet 4 is taken out (see FIG. 9C).

  Next, after the buffer mechanism 53 of the sheet conveying apparatus 50 is in a locked state where the buffer mechanism 53 does not act, the surface sheet 4 sucked and held by the sheet adsorbing member 90 is moved by the sheet conveying apparatus 50 to the sheet placement unit 40. To the adhesive application device 60. Then, the top sheet 4 is moved above the coating roller 63 by the sheet conveying device 50, the coating roller 63 having an adhesive layer formed on the back surface of the top sheet 4 is brought into contact, and the adhesive on the outer peripheral surface of the coating roller 63 is removed. It apply | coats to the back side of the surface sheet 4 (refer FIG.9 (d)).

  When the adhesive is applied, since the buffer mechanism 53 is locked by the buffer lock mechanism 54 of the sheet conveying device 50, the sheet adsorbing member 90 via the surface sheet 4 by the adhesive force of the adhesive on the outer peripheral surface of the application roller 63. As a result, the sheet adsorbing member 90 flutters and the contact state between the top sheet 4 and the application roller 63 changes, and the adhesive can be prevented from being applied unevenly. An adhesive can be uniformly applied to the back surface of the substrate.

  On the other hand, in the core material conveying device 20, the core material 3 placed on the core material placing unit 10 is placed on the core material 3 corresponding to the surface sheet 4 conveyed by the sheet conveying device 50. The suction holding part 23 attached to the tip is brought into contact, a negative pressure is supplied to the suction holding part 23, and the core material 3 is sucked by the suction cup part 24. At this time, the suction holding portion 23 is brought into contact with the approximate center of gravity of the core material 3. The core material 3 is taken out of the core material holding unit 10 by raising the suction holding unit 23 at the tip by the multi-joint robot 22 while the core material 3 is adsorbed and held by the suction holding unit 23.

  On the core material conveying device 20 side, when the core material 3 is placed on the core material placement unit 10, the core material 3 is preliminarily placed at a position corresponding to the shape of the core material 3. The placement position is stored, and the articulated robot 22 is controlled based on the stored shape and placement position of the core material 3, and the core material 3 corresponding to the surface sheet 4 is sucked by the suction holding unit 23. Hold. Or it was equipped with the camera which image | photographs the core material 3 mounted in the core material mounting part 10, and respond | corresponded with the surface sheet 4 by image-analyzing the core material 3 of the core material mounting part 10 image | photographed with the camera. The position and orientation of the core material 3 may be recognized, and the articulated robot 22 may be controlled based on the recognition.

  Further, in the core material support device 30, the auxiliary support surface 37a of the auxiliary support member 37 is substantially flush with the mounting table 32 by the auxiliary support cylinder 38 of the auxiliary support device 36 (FIG. 10E). See).

  Then, the core material 3 taken out from the core material support unit 10 by the core material transport device 20 is transported to the core material support device 30 and mounted on the mounting table 32 of the core material support device 30. At this time, the decorative side surface of the core material 3 on which the top sheet 4 is folded and pasted is directed to the end pressing unit 70B side (left side in FIG. 10) of the pressing device 70, and the decorative side surface is the auxiliary support device. It is placed in contact with the 36 positioning pieces 39. When the core material 3 is placed on the mounting table 32 of the core material support device 30, negative pressure is supplied to the negative pressure acting portion 33, and the lower surface of the core material 3 is adsorbed by the suction cup portion 34 to fix the core material 3. Thereafter, the supply of negative pressure to the suction holding unit 23 in the core material transporting device 20 is stopped, the suction of the core material 3 by the suction cup unit 24 is released, and then the suction holding unit 23 is raised by the articulated robot 22. It keeps away from the core material 3 (refer FIG.10 (f)).

  The core material supporting device 30 supports the core material 3 and the suction holding portion 23 of the core material conveying device 20 is separated from the core material supporting device 30 and is adsorbed by the sheet adsorbing member 90 and the adhesive is applied to the back surface. The top surface sheet 4 is conveyed to the core material supporting device 30 by the sheet conveying device 50 (see FIG. 11G). Then, after the orientation of the surface sheet 4 adsorbed by the sheet adsorbing member 90 is matched with the direction of the core material 3 supported by the core material support device 30, the surface sheet 4 is placed on the core material 3.

  Thereafter, the supply of negative pressure to the fixed suction unit 94 and the movable suction unit 95 in the sheet suction member 90 is stopped, and the suction of the topsheet 4 by the suction cups 94a and 95a is released, and then the articulated robot 52 As a result, the sheet adsorbing member 90 is lifted away from the core material support device 30 (see FIG. 11H). Since the adhesive is applied to the back side of the top sheet 4, even if the sheet adsorbing member 90 is raised, the top sheet 4 does not fall from the core material 3 due to the adhesive force of the adhesive, It will be mounted in a good state.

  Once the top sheet 4 coated with the adhesive is placed on the core material 3, next, the upper surface of the pressing device 70 located on the other end side in the longitudinal direction of the main body 31 (right side in FIG. 12) of the core material support device 30. The roller support member 72 in the pressing unit 70 </ b> A is lowered to a position where the lower end of the pressing roller 71 is substantially the same height as the upper surface of the core material 3, and the upper unit main body 73 is moved toward one end in the longitudinal direction of the main body 31. The pressure roller 71 is moved to roll from the side opposite to the decorative side surface of the core material 3 to the decorative side surface (see FIG. 12 (i)). By the rolling of the pressing roller 71, the top sheet 4 is sequentially pressed against the top surface of the core material 3 from the side opposite to the decorative side surface of the core material 3 toward the decorative side surface, and the core material 3 and the top sheet. 4 is pushed out to the decorative side surface, and the core material 3 and the top sheet 4 are stuck in a state of being in close contact with an adhesive interposed therebetween. Moreover, since the lower surface is supported by the auxiliary support member 37 on the decorative side of the core material 3, the core material 3 is not bent by the pressing of the pressing roller 71, and the top sheet 4 is pressed and pasted well. Can.

  When the upper unit main body 73 (pressing roller 71) of the upper surface pressing unit 70A reaches the decorative side surface side of the core material 3, the roller support member 72 is raised to move the pressing roller 71 away from the upper surface of the top sheet 4, and The unit main body 73 is moved to the original position on the other end side in the longitudinal direction of the main body 31 in the core material supporting device 30 and the unit driving cylinder 86 in the end pressing unit 70B of the pressing device 70 is driven to drive the end unit main body 85. Is moved to the main body 31 side (see FIG. 12J).

  When the end unit main body 85 of the end pressing unit 70B is moved to the main body 31 side (to a position close to the decorative side surface of the core member 3), the upper surface pressing plate 80 is lowered by the first drive mechanism 87, and the upper surface pressing plate is moved. 80, the top sheet 4 is pressed toward the core material 3 on the upper surface side near the decorative side surface of the core material 3 (see FIG. 12 (k)). At this time, a part of the surface sheet 4 is pressed into the groove 3a of the core material 3 by the protrusions 80a of the upper surface pressing plate 80, and the surface sheet 4 is stuck along the groove 3a.

  Then, the first drive mechanism 87 of the end pressing unit 70B fixes the position of the upper surface pressing plate 80 in contact with the top sheet 4 and releases the pressing to the core material 3 side. The auxiliary support member 37 of the auxiliary support device 36 at 30 is rotated downward by the auxiliary support cylinder 38 to release the support of the lower surface of the core material 3 near the decorative side surface (see FIG. 13 (l)). In addition, by turning the auxiliary support member 37 downward, the positioning piece 39 part is separated from the predetermined side surface of the core material 3, and the top sheet 4 can be folded back to the predetermined side surface side of the core material 3. .

  Next, by the second drive mechanism of the end pressing unit 70B, the side pressing plate 81 is lowered to bend the top sheet 4 toward the decorative side of the core member 3, and the side pressing plate 81 is moved in the direction of the core member 3. The top sheet 4 thus bent is pressed toward the decorative side surface of the core material 3 (see FIG. 13 (m)).

  Subsequently, by the third drive mechanism of the end pressing unit 70B, the lower surface pressing plate 82 is advanced to the core material 3 side, the top sheet 4 is bent to the lower surface side of the core material 3, and the lower surface pressing plate 82 is raised. The folded top sheet 4 is pressed to the lower surface side of the core material 3 (see FIG. 13 (n)). At this time, since the upper surface pressing plate 80 is in contact with the upper surface side of the core material 3 in a fixed state, even if the lower surface pressing plate 82 is pressed from below, the core material 3 will not bend. The top sheet 4 can be pressed against the lower surface of the core material 3 in a good state.

  And, for a predetermined time until the adhesive effect of the adhesive applied to the top sheet 4 appears (for example, 15 sec to 4 min after the adhesive is applied to the back side of the top sheet 3), the decorative side surface side of the core material 3 is The upper surface pressing plate 80, the side surface pressing plate 81, and the lower surface pressing plate 82 are pressed, and after the predetermined time has elapsed, the upper surface pressing plate 80, the side surface pressing plate 81, and the lower surface pressing plate 82 are moved back to their original positions. (See FIG. 14 (o)). Thereby, the manufactured product 2 in which the top sheet 4 is attached to the core material 3 is supported by the core material support device 30.

  Thereafter, the end unit main body 85 of the end pressing unit 70 </ b> B is retracted to the original position to move away from the manufactured product 2 supported by the core material support device 30, and the tip of the articulated robot 22 in the core material transport device 20. The suction holding part 23 attached to is moved closer to the upper surface side of the manufactured product 2 (see FIG. 14 (p)).

  Then, the suction holding portion 23 of the core material transporting device 20 is brought into contact with the upper surface of the manufactured product 2 to apply a negative pressure to suck and hold, and the negative pressure applied to the negative pressure acting portion 33 in the core material supporting device 30 is reduced. After the supply is stopped and the suction of the lower surface of the core material 3 by the suction cup portion 34 is released, the suction holding portion 23 is raised by the articulated robot 22 and the manufactured product 2 is picked up from the core material support device 30 (FIG. 14). (See (q)).

  The manufactured product 2 sucked and held by the suction holding unit 23 of the core material transporting measure 20 is transported to the manufactured product mounting unit 110 by the articulated robot 22, and the manufactured product 2 is placed on the manufactured product mounting unit 110 in a predetermined direction. By mounting, manufacture by the surface sheet sticking system 1 is completed. In addition, a series of operation | movement in the above-mentioned surface sheet sticking system 1 is controlled automatically by the control apparatus 120, and can attach the surface sheet 4 to the core material 3 automatically.

  Thus, according to the surface sheet sticking system 1 of the present embodiment, the core material 3 that has been previously cut into a predetermined shape (triangular shape, trapezoidal shape, rectangular shape, etc.) is placed on the core material placing portion 10. The top sheet 4 that has been cut in a shape corresponding to the core material 3 is placed on the sheet placing portion 40, and the core material 3 placed on the core material placing portion 10 is cored by the core material conveying device 20. While transporting and supporting the material to the material support device 30, the adhesive sheet is applied to the back surface of the surface sheet 4 by the adhesive application device 60 while the surface sheet 4 placed on the sheet placement unit 40 is conveyed by the sheet conveyance device 50. In addition, since the top sheet 4 can be transported and placed on the core material 3 supported by the core material support device 30 and pressed on the core material 3 side by the pressing device 70, it is cut into a predetermined shape in advance. The surface sheet 4 cut into a shape corresponding to the core material 3 is skillful. Technology can be easily attached kicking it without the need for.

  Further, the top sheet 4 to which the adhesive is applied by the pressing device 70 is pressed against the core material 3 side, so that the top sheet 4 is affixed mechanically. By optimizing the pasting operation by the apparatus 70, it is possible to easily perform pasting equivalent to that of a skilled worker, reduce costs, and reduce unevenness for each pasting of the topsheet 4 as much as possible. The top sheet 4 can be neatly adhered to the core material 3.

  Further, the adhesive is applied by bringing the back surface of the top sheet 4 being transported through the air with the surface (upper surface) being sucked and held by the sheet transport device 50 into contact with the rotating application roller 63 of the adhesive application device 60 from above. This is a configuration employing a new method. Thereby, it is not necessary to provide a feeding mechanism for feeding the topsheet 4 to the adhesive application device 60, and the cost of the system can be reduced by simplifying the configuration of the adhesive application device 60. Further, since it is not necessary to provide a mechanism for feeding the top sheet 4 to the adhesive coating device 60, when the adhesive is applied to the back surface of the top sheet 4, the top sheet 4 is transferred from the sheet conveying device 50 to the adhesive coating device. 60, and the sheet conveying device 50 does not need to receive the surface sheet 4 from the adhesive application device 60. The time can be shortened by the delivery of the surface sheet 4, and the production efficiency is relatively improved. A manufactured product can be manufactured at low cost.

  Further, since the adhesive is applied by bringing the application roller 63 of the adhesive application device 60 into contact with the back surface of the surface sheet 4 being conveyed by the sheet conveyance device 50, unevenness in the application condition of the adhesive is eliminated. The adhesive can be applied uniformly, and the surface sheet 4 can be neatly adhered to the core material 3 without requiring a skilled technique by applying the uniform adhesive.

  By the way, when the adhesive application device 60 includes a spray for spraying the adhesive, it is almost impossible to apply all of the adhesive sprayed from the spray to the back surface of the top sheet 4. A mist-like adhesive will be scattered around 4. Therefore, when applying the adhesive by spraying, it is necessary to have a dust collector that collects the sprayed mist-like adhesive, which makes the overall system configuration large and increases the cost of the system There is. Further, when the adhesive is applied by spraying, as described above, since the mist-like adhesive is scattered, the scattered adhesive does not adhere to the sheet conveying device 50 that conveys the surface sheet 4 or the like. It is necessary to take measures, and there is a problem that the cost becomes high in this respect as well. On the other hand, in this embodiment, the adhesive is applied to the back surface of the top sheet 4 by bringing the application roller 63 on which the adhesive layer is formed into contact, and the adhesive is not scattered. Compared to the case of using a dust collector, it is not necessary to provide a dust collector or to take measures against the adhesive on the sheet conveying device 50 and the like, and it is possible to avoid an increase in the cost associated with the system.

  Further, a plurality of sheet adsorbing members 90 for adsorbing and holding the surface sheet 4 are prepared in advance according to the shape (size) of the surface sheet 4, and each sheet adsorbing member 90 is independently attached to the sheet conveying device 50. Since the sheet adsorbing member storage device 100 is provided, the sheet adsorbing member 90 corresponding to the shape of the top sheet 4 can be taken out from the sheet adsorbing member storage device 100 and mounted on the sheet conveying device 50. It becomes possible to correspond to the shape of the topsheet 4 and can be easily applied to various types without requiring a skilled technique, and the topsheet 4 can be securely attached to the core material 3 even if the shape changes. it can.

  By the way, as the sheet adsorbing member 90 for holding the surface sheet 4 in the sheet conveying apparatus 50, for example, only the sheet adsorbing member 90 having a size matching the smallest surface sheet 4 can be used so as to be compatible with the surface sheet 4 having various shapes. If the surface sheet 4 larger than the sheet adsorbing member 90 is held, a portion of the surface sheet 4 that is not held by the sheet adsorbing member 90 hangs down, and an adhesive is applied to the back surface of the surface sheet 4 by the adhesive application device 60. The problem that it becomes impossible to apply | coat and the surface sheet 4 cannot be mounted in a favorable state on the core material 3 arises. Therefore, it is conceivable that the sheet adsorbing member 90 has a size that matches the largest surface sheet 4. However, in this case, if the surface sheet 4 smaller than the sheet adsorbing member 90 is held, the outside air flows from the portion that is not adsorbing the surface sheet 4, so the adsorbing force of the surface sheet 4 is reduced and the surface sheet 4 is removed. There is a risk that it cannot be sufficiently held. On the other hand, in the present embodiment, a plurality of sheet adsorbing members 90 having different sizes are prepared, and the sheet adsorbing member 90 having a size corresponding to the shape of the topsheet 4 is used. It can be surely solved.

  The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements can be made without departing from the scope of the present invention as described below. And design changes are possible.

  For example, in the above-described embodiment, the core material conveying device 20 and the sheet conveying device 50 using the multi-axis multi-joint robots 22 and 52 are shown, but the present invention is not limited to this and extends in different directions. An apparatus in which a connecting portion that removably connects the sheet adsorbing member with a plurality of rails may be used in a three-dimensional manner, and the same effects as described above can be achieved.
