The pressure roller 50 is a roller that presses the second sheet member 20 against the first sheet member 10, and in this embodiment, can perform both pressure and heating.

The first sheet table 60 is a table on which the support section 30 of the first sheet member is moved.
2,63. The attaching portion 61 is a portion where the first sheet member 10 and the second sheet member 20 are actually attached. When the first or second support area of the support portion 30 of the first sheet member is located on the attaching portion 61, the supply portions 62 and 63 collect the sheet member that has been pasted, and collect the new first sheet member 10 Is the part that supplies

When the first support region of the support portion 30 of the first sheet member is on the sticking portion 61, the second support region is
In the supply section 62 (the state shown in FIG. 1), the support section 30 of the first sheet member moves, and the first support area is changed to the supply section 63.
, The second support area moves to the attaching section 61.

The second sheet table 70 is a table having a peeling section 71 and a supply section 72. The peeling portion 71 is formed from the second sheet member 20 supported by the support portion 40 of the second sheet member.
This is the part where the release sheet is released. The supply section 72 is a section that supplies a new second sheet member 20.

FIG. 2A is an enlarged view of a main part of the peeling section 71. In addition, portions that are not necessary for the description of the peeling portion 71 are appropriately simplified for easy understanding. Second
The sheet member 20 includes a base layer 21, an adhesive layer (sticking layer) 2
2. It has a release sheet (release layer) 23, and it is necessary to peel off the release sheet 23 before attaching to the first sheet member 10. The sheet member bonding apparatus according to the present embodiment includes a separation roller 81 for automatically separating the separation sheet 23.

The peeling roller 81 is a peeling means having an adhesive surface, and peels off the peeling sheet 23 from the adhesive layer 22 by pressing against the peeling sheet 23 and rotating. Therefore, it is necessary that the adhesive strength between the peeling roller 81 and the peeling sheet 23 is stronger than the adhesive strength between the peeling sheet 23 and the adhesive layer 22. After peeling off the end, the peeling sheet 23 is transported to a predetermined position while completely peeling off the peeling sheet 23 by a peeling sheet feeding mechanism (not shown).

In the peeling section 71, the second sheet member 20 from which the peeling sheet 23 has been peeled is supported by the supporting section 40 of the second sheet member and conveyed to the sticking section 61. FIG.
FIG. 7 is a view showing an attaching operation in an attaching section 61. Immediately after the second sheet member 20 has been conveyed (FIG. 3A), the second sheet member 20 includes the center support portion 41 and the end portion support portion 4.
2 and 43 are adsorbed and supported. Further, the first sheet member 10 is suction-supported by the support portion 30 of the first sheet member.

In the attaching operation, first, the end supporting portion 42 is moved to the second position.
The first sheet member 10 while holding the sheet member 20 by suction
(FIG. 3 (b)) to act as a starting end pressing section. At this time, since the second sheet member 20 is pulled by the end support portion 42, the suction support of the central support portion 41 is partially released.

FIG. 4A is an enlarged view of the end support portion 42. FIG. A rubber member 42a is provided as an elastic body on the surface of the end support portion 42 on which the second sheet member 20 is adsorbed, in order to absorb dimensional variations in the thickness of each sheet member and to prevent scratches and the like. . Further, a corner R is provided in the ridge line portion 42b of the rubber member 42a. In addition, the end support part 4
Although not shown in an enlarged manner, 3 has the same form as the end support portion 42.

Next, after the end supporting portion 42 returns to the original position, the pressing roller 50 presses the second sheet member 20 while heating the first sheet member 10 to join them sequentially from the end. (FIG. 3C).

When the pressure roller 50 advances, the pressure roller 50
The end support portion 43 moves toward the first sheet member 10 in accordance with the position (FIG. 3D), and acts as the end end support portion, so that the second sheet member 20 is not forcibly pulled. Thus, the first sheet member 10 can be naturally contacted.

In the above description of the operation, the case where pressure is applied from the left side to the right side in FIG. 3 has been described. However, after the pressing roller 50 moves to the right side in FIG. If replaced, the pressure roller 50 can be pressed from the right side. In this case, the end support portion 43 functions as a start end pressing portion, and the end support portion 42 functions as an end end support portion. The sticking can be performed without performing the operation.

According to the present embodiment, since the peeling sheet 23 is automatically peeled by the peeling roller 81, there is no need for an operator to manually perform the peeling operation. In addition, the end support 4
Since the second sheet member 20 is provided, the second sheet member 20 can be placed on the first sheet member 10 in order from the end, and can be bonded together so that air bubbles and the like do not enter.
Further, since the first sheet member support portion 30 and the second sheet member support portion 40 are provided, the first sheet member 10 and the second sheet member
The conveyance of the sheet member 20 can be performed automatically, the work can be performed efficiently, and the positioning can be performed accurately.

(Modifications) Various modifications and changes are possible without being limited to the embodiment described above, and they are also within the equivalent scope of the present invention. (1) In the present embodiment, an example in which the peeling roller 81 having adhesiveness is used as a peeling unit of the peeling sheet 23 has been described. However, the present invention is not limited to this. For example, FIGS. Such a form may be used. The form of FIG.
