Next, a sheet sticking method using the sheet sticking device SM of the above embodiment will be described.
First, as shown by a solid line in FIG. 1, with the original fabric RS being fed from the feed roller 11 to the take-up shaft 15, the linear motor LM4 is driven and the upper table 53 is lowered downward, and transport means (not shown) As a result, the adherend AH is placed and held on the upper surface of the upper table 53. Next, the linear motor LM4 is driven, and the upper table 53 is moved upward. At this time, the original fabric RS and the adherend AH are kept at an interval where they do not come into contact with each other. The adherend AH is placed on the upper surface of the upper table 53 so that its center is located at the rotation center of the cutting blade 31.

  When it is detected that the upper table 53 has been moved upward, the pressing roller 22 is moved to the right from the position indicated by the solid line in FIG. 1, and the pressing roller 22 presses from the release sheet RL side to remove the original fabric RS. Affixed to the upper surface of adherend AH. At this time, the adhesive body AM is heated to a predetermined temperature by the heating means provided on the upper table 53 and bonded. When the pressing roller 22 passes over the adherend AH and reaches the position shown in FIG. 4A, the cutting means 3 moves the cutting blade 31 from the standby position shown by the solid line in FIG. 1 to the cutting position that penetrates the original fabric RS. In this state, the rotation motor DM3 is driven and the arm 32 is rotated, thereby forming a cut with a predetermined shape along the contour of the adherend AH in the original fabric RS. By this cutting, the adhesive sheet AS, the inner unnecessary sheet RLi, the unnecessary adhesive sheet US, and the outer unnecessary sheet RLo are formed.

  When the cutting means 3 returns to the initial position after the cut is formed as described above, the linear motion motor LM1 is driven, and the pressing roller 43 is moved rightward from the position indicated by the solid line in FIG. As shown to 4 (a), the press roller 43 presses from the base material sheet BS side, and affixes the connection sheet | seat CS so that the inner side unnecessary sheet | seat RLi and the outer side unnecessary sheet | seat RLo may be connected. When the pressing roller 43 passes the adherend AH and reaches the position shown in FIG. 4A, the linear motor LM5 is driven and the peeling plate 61 moves to the lower left as shown in FIG. 4B. Then, the hot air blowing means 71 and the cold air blowing means 81 are operated, and hot air is ejected from the hot air openings 64a and 64b. At this time, as shown in FIG. 4A, the partition plates 74 and 75 are located in the opening (center in FIG. 3) in the space SP of the pipe 82, thereby closing the opening. The opening 64c is not formed, and the gas blown from the cold air blowing means 81 is not blown into the space SP.

  Thereafter, the linear motion motors LM1 and LM3 are driven, and the pressing rollers 22 and 43 and the table 52 are moved in the left direction in synchronization. At the same time, the rotation motors DM1 and DM2 are also driven in synchronization and removed. The object RM is wound up.

  Then, as shown in FIG. 4 (b), when the left end of the cut reaches the lower left end of the peeling plate 61, the peeling object RM is bent by the peeling plate 61 and guided upward, and the adhesive sheet AS is And it peels from the inner side unnecessary sheet | seat RLi in the state affixed on the upper surface of the to-be-adhered body AH. At this time, peeling can be promoted by operating the ultrasonic vibrator 62 to vibrate the peeling plate 61.

  When the adhesive sheet AS is peeled from the inner unnecessary sheet RLi, the width of the unnecessary adhesive sheet US changes as shown in FIGS. 5B and 5C. Although the width of the unnecessary adhesive sheet US changes as described above, if the hot air continues to be blown from the entire opening 64, the hot air is blown to the adhesive sheet AS, and the adhesive sheet AS is heated more than necessary. Will be firmly bonded. In order to prevent this, the rotation motor DM4 is driven, and the partition plates 74 and 75 are once moved in a direction away from each other according to the width of the unnecessary adhesive sheet US, and moved again so as to approach each other. At this time, the partition plates 74 and 75 are moved away from each other to form a space SP leading to the heating preventing opening 64c, and the gas blown from the cold air blowing means 81 is blown into the space SP and heated. A gas for preventing the adhesive sheet AS from being heated is blown from the prevention opening 64c. Accordingly, warm air is blown to the outer unnecessary sheet RLo corresponding to the unnecessary adhesive sheet US, and cold air is blown to the inner unnecessary sheet RLi. Thereafter, the connecting sheet CS and the separation object RM are simultaneously wound around the winding shaft 15 and return to the state shown in FIG. 1, and thereafter the same operation as described above is repeated. In addition, by blowing cold air on the inner unnecessary sheet RLi, there is also an effect of weakening the adhesive force between the inner unnecessary sheet RLi and the adhesive sheet AS and facilitating their peeling.

  According to the above embodiment, the unnecessary adhesive sheet US separated from the adhesive sheet AS is heated to a predetermined temperature simultaneously with the folding of the raw material RS by the peeling plate 61 of the bending means 6, so that the unnecessary sheet US is softened. Since the unnecessary adhesive sheet US is bent in a state, the unnecessary adhesive sheet US can be prevented from being finely cracked. As a result, generation of dust is effectively suppressed, and problems such as contamination of the surrounding environment do not occur. Further, the adhesive sheet AS is heated more than necessary by changing the heating region of the unnecessary adhesive sheet US and the cooling region of the adhesive sheet AS as the inner unnecessary sheet RLi peels from the adhesive sheet AS. This is surely prevented, and there is no inconvenience that an adhesion failure of the adhesive sheet AS occurs. Further, since the release sheet RL is peeled from the adhesive sheet AS while the release plate 61 is slightly vibrated, it is possible to prevent the occurrence of peeling failure.

The sheet manufacturing apparatus can also be configured by the bending means 6 for bending the peeling object RM and the heating means 7 capable of heating the unnecessary adhesive sheet US simultaneously with the bending of the peeling object RM by the bending means 6. In this case, the feeding unit 1 is configured to feed the original fabric RS in a state inverted upside down from the above embodiment, and the cutting unit 3 is configured not to divide the release sheet RL, and the winding shaft 15 Thus, only the unnecessary adhesive sheet US may be wound up.

  In the above embodiment, the adhesive AM is attached to the adherend AH and then divided into the adhesive sheet AS and the unnecessary adhesive sheet US by the cutting means 3. However, the adhesive sheet AS and the unnecessary adhesive are separated. The present invention can also be applied to a structure in which the adhesive sheet AS is attached to the adherend AH while the raw material RS is folded by the bending means 6 after being divided into the sheet US, and the peeling object RM is wound around the winding shaft 15. .
