At the upper end thereof, there is provided a substrate placement section 100, and this board placement section 1
00 is provided with a plurality of transport rollers 102 that are driven to rotate.

The operation of the tacking laminator P based on the above configuration will be described. The sheet-like member F for the laminator that is wound is attached to the sheet-like member attaching roller 12 in the laminator P for temporary attachment. Here, the state where the suction surfaces of the suction boxes 44a and 44b face downward as shown in FIG.
b is referred to as being in a horizontal state, while the state in which the suction surfaces of the suction boxes 44a and 44b face the traveling unit 74 is referred to as the vertical state of the suction boxes 44a and 44b.

After the sheet-like member F is passed between the conveying rollers 16a and 16b, the sheet-like member F is supported by the conveying rollers 18 and led out to the front surface of the suction unit 40. In other words, the sheet-like member F passes through the conveyance path indicated by a dashed line drawn from the sheet-like member mounting roller 12 in FIG. 2 until reaching the front surface of the suction unit 40. In this case, the suction boxes 44a and 44b are in a vertical state. That is, the state shown in FIG. Note that the two-dot chain line in FIG. 2 indicates the transport path of the backing sheet, and in the lower sheet-like member supply mechanism unit 10, the backing sheet passes through the conveying path along the outer periphery of the sheet-like member mounting roller 12. It is taken up by the take-up roller 14.

Next, suction of the suction boxes 44a and 44b is started to suck the sheet-like member F. This is the first
Process. In this state, the suction boxes 44a, 44b
Is rotated so as to be horizontal. Simultaneously with this rotation, the substrate K is introduced into the main unit A. That is, the substrate K
Is placed on the substrate transfer device B and then
And is disposed between the pair of suction units 40 by a transport roller 62 that is driven to rotate by the main unit A.
This operation is the second step. Then, as shown in FIG. 4B, the suction boxes 44a and 44b are in a horizontal state, and the substrate K stops at a predetermined position. More specifically, first, the sheet-like member F is first placed in the suction boxes 44a,
4B, it is introduced slightly longer, and then the blade 74a is moved to cut at a predetermined position, so that the edge of the substrate K in the state of FIG. And the ends of the sheet-like member F can be aligned.

Then, as shown in FIG. 4B, when the suction boxes 44a and 44b are in a horizontal state and the sheet-like member F is being sucked, the substrate K
a, the suction boxes 44a, 4b
4b approaches toward the substrate K. In other words, the transport welding unit 32 is moved closer to the substrate K by driving the transport welding unit cylinder 56. In this state,
As shown in FIG. 4C, the welding rod 52 moves toward the substrate K, and presses the sheet-shaped member F toward the substrate K. The welding rod 52 includes the suction box 44a and the suction box 4
The substrate K reaches the substrate K through the opening S between the holes 4b. Since the welding rod 52 is heated, the area of the sheet-shaped member F where the welding rod 52 is pressed is welded to the substrate K. This operation corresponds to the third step.

When the welding is completed, the suction box 44a,
While stopping the suction of the suction box 44b,
a, 44b are returned to the isolated state from the state approaching the substrate K. That is, the transport welding unit 32 is separated from the substrate K by driving the transport welding unit cylinder 56. After that, the suction unit 40 is rotated, and FIG.
The vertical state is set as shown in FIG. This operation is the fourth step.

In this vertical state, the suction boxes 44a,
After the suction of 44b is started, as shown in FIG.
The suction unit 40 is again rotated to be in the horizontal state, and the transfer of the substrate K is started. That is, the substrate K is transported by the transport rollers 62 and the transport belt 68. This operation is the fifth step. In addition, in the suction boxes 44a and 44b, the suction is stopped before the horizontal state.

When the suction boxes 44a and 44b are in a horizontal state, the transport of the substrate K is continued until the end of the substrate K reaches a predetermined position. Then, when the end of the substrate K reaches a predetermined position, the suction boxes 44a and 44b are returned to the vertical state, and the cutting process is performed (see FIG. 5G). This operation is the sixth step. The distance is measured based on the rotation of the transfer roller 62, and the transfer is stopped when the transfer has been performed for a predetermined distance. In the cutting process, the backup 82 is moved to the transport unit 74 side, and cutting is performed by pressing the blade portion 74a against the end of the backup 82. In other words, when the cylinder 84 is driven, the backup 82 passes through the opening S between the suction box 44a and the suction box 44b and passes through the blade 74a.
To reach and contact. In this state, the traveling unit 74 travels, so that the blade portion 74a performs cutting while pressing the sheet-like member F against the backup 82. When performing this cutting process, the suction box 4
The sheet-like member F is sucked by 4a and 44b.

When the cutting is completed, the substrate K is transported.
The substrate K to which the temporary attachment has been performed in this way will be subjected to the actual welding in a later step.

As described above, in the tacking laminator P of this embodiment, the suction boxes 44a and 44b are rotated along the axis perpendicular to the transport direction.
Since the end portion of the sheet member F is arranged on the substrate K,
It is possible to reliably transport the sheet-like member, and it is possible to prevent problems when transporting the sheet-like member.

In the above description of the operation, FIG.
(D), as shown in FIG.
Although a and 44b are temporarily returned to the vertical state and then returned to the horizontal state, this operation may be omitted.
