Further, the transfer conveyor 9 may be provided above and below, similarly to the transfer conveyor 3. In such a case, the stacked body of the

sheets

710 and 720 is transported while being sandwiched between the upper transport conveyor disposed above and the lower transport conveyor disposed below. A concave portion and a convex portion may be formed on the upper conveyor.

As a result, it is possible to improve the transferability and conveyance stability of the laminate of the

sheets

710 and 720 after being cut by the cutting unit 4 to the transfer conveyor 9.

Here, the conveyance speed in the conveyance conveyor 9 is about 3% faster than the conveyance speed in the conveyance conveyor 3 and the cutting part 4.

The transport conveyor 11 includes a transport conveyor 11a and a transport conveyor 11b that are arranged at a predetermined interval in a cross direction CD that intersects the transport direction MD. The

conveyors

11a and 11b are provided with a suction mechanism (not shown) in a state in which the outer ends in the width direction of the

cut sheets

710 and 720 conveyed by the conveyor 9 are attracted to the conveyance surface. Can be transported. A pusher 13 is disposed between the conveyor 11a and the conveyor 11b.

The pusher 13 is disposed so as to be movable downward in the direction in which the

sheets

710 and 720 conveyed by the conveyor 11 are separated from the conveying surfaces of the

conveyors

11a and 11b.

After a predetermined number of

sheets

710 and 720 separated from the

conveyors

11a and 11b are stacked, the stacked body 800 is formed, the stopper S is released, and the stacked body 800 is transferred to the pressing device 15 by the conveyor 12. It is conveyed toward.

The pressing device 15 conveys both ends of the laminated body 800 formed by laminating the

cut sheets

710 and 720 along the conveying direction while being pressed from the non-contact surface side of the conveying conveyor 14 by the pressing unit. It is configured.

The press device 15 includes a plurality of

rollers

201, 202, 203,

press belts

204 a, 204 b wound around the plurality of

rollers

transport belts

205, 206 that transport the stacked body 800.

Any one of the plurality of

rollers

201, 202, 203 is connected to a drive source and controlled to drive the

press belts

204a, 204b in a predetermined transport speed and transport direction. The conveyor belt 205 corresponds to the conveyor belt 14.

The

press belts

204a and 204b are wound around

rollers

201, 202, and 203, and are configured to be driven in accordance with the transport speed and transport direction of the laminate 800. The

press belts

204a and 204b are arranged at a predetermined interval in a cross direction CD orthogonal to the transport direction MD. Here, the predetermined interval is an interval at which the

press belts

204a and 204b can abut on both

end portions

800A and 800B in the cross direction CD of the laminate 800.

The

press belts

204a and 204b according to the present embodiment are formed in a round tube shape. That is, the cross sections of the

press belts

204a and 204b are substantially circular.

The distance D2 between the outermost peripheral portion of the

press belts

204a and 204b wound around the

rollers

201, 202, and 203 and the furthest outermost part from the rotation axis of the rollers and the conveyance surface of the conveyance belt 205 is the lamination height D1 of the laminate 800. It is formed shorter. The interval D2 is adjusted to a height that prevents the chemical solution from being squeezed more than necessary.

Further, the

press belts

204a and 204b are inclined so that the distance between the outermost peripheral portion of the

press belts

204a and 204b and the conveying belt 205 gradually decreases from D1 to D2. Thereby, force is gradually applied to both

end portions

800A and 800B on the outer side in the width direction of the stacked body 800 to be conveyed.

According to the manufacturing method and the manufacturing apparatus 10 according to the present embodiment, both

end portions

800A and 800B excluding the central region 800C of the stacked body 800 can be conveyed while being pressed by the pressing device 15 configured as described above. .

In the manufacturing method according to the present embodiment, a predetermined number of sheets are stacked after the

sheets

71 and 72 are conveyed and cut in a stacked state. The

sheets

71 and 72 stacked during conveyance are sufficiently pressed against each other by the transfer conveyor 3, but in the stacking step S106 after cutting, the pressing force is weaker than the force pressed by the transfer conveyor 3 during transfer. .

One reason is that the entire surface of the laminated body 800 can be pressed after the laminating step S106, but the chemical solution moves to the lower layer side of the laminated body 800, and the amount of liquid on the upper layer side is insufficient. The pressure cannot be increased.

As described above, when there is a difference between the adhesive force between the sheets stacked during conveyance and the adhesive force between the sheets when stacked in the stacking step S106, a plurality of strongly pressed sheets are taken out collectively. Can happen.

On the other hand, in the manufacturing method according to the present embodiment, after the stacking step S107, the entire surface of the stacked body 800 that is stacked a predetermined number of times is not uniformly pressed, but the both

end portions

800A and 800B are removed by the pressing device 15. Press.

For this reason, the adhesiveness between the

sheets

710 and 720 of the laminated body 800 after the lamination of a plurality of sheets is not unnecessarily high, and the adhesion between the sheet 720 and the next sheet 710 can be ensured. Can be prevented from being taken out.

Further, since the entire surface of the laminate 800 is not pressed, variations in the liquid content due to the chemical solution moving from the upper sheet to the lower sheet of the laminate 800 can be prevented.

According to the manufacturing method and the manufacturing apparatus 10 according to the present embodiment, the amount of the predetermined chemical liquid soaking into the sheet can be made uniform from the sheet on the upper layer side to the sheet on the lower layer side. Further, it is possible to prevent the ease of taking out from being reduced by increasing the amount of the predetermined chemical liquid that permeates into the sheet.

In the manufacturing apparatus 10 according to the present embodiment, the

press belts

204a and 204b are formed in a round tube shape. Thereby, the sheet | seat of the upper surface side which comprises the laminated body 800, and the

rollers

202 and 203 which comprise the press apparatus 15 can be released | separated, and entanglement to the

rollers

202 and 203 of the sheet | seat of an upper surface side can be prevented.

As described above, the present invention has been described in detail using the above-described embodiments. However, it is obvious for those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modified and changed modes without departing from the spirit and scope of the present invention defined by the description of the scope of claims. Therefore, the description of the present specification is for illustrative purposes and does not have any limiting meaning to the present invention.

A laminate test consisting of 72 sheets was packaged by the package body, and a take-out test was conducted in which the sheets were taken out one by one. The results are shown in FIGS. 7 (a) to (c). Specifically, a production line was configured in which four sheets were stacked to form one set. That is, a laminate consisting of 18 sets was prepared and enclosed in a package.

FIG. 7 (a) shows the result of the take-out test of the laminate that did not perform the pressing step, and FIG. 7 (b) shows the result of the take-out test of the laminate that pressed the entire surface. These represent the result of the taking-out test of the laminated body which performed the press process by the press apparatus which concerns on embodiment. The vertical axis in FIGS. 7A to 7C represents the amount of the next sheet pulled out when a pop-up (a phenomenon in which the next sheet is taken out after one sheet) occurs. The unit is length (mm).

According to the results, it was found that the laminate that did not perform the pressing step has a strong tendency to take out four sheets at a time. That is, it was found that one set of sheets stacked on the production line can be easily taken out together. Further, it was found that a set of sheets stacked on the production line can be easily taken out even in the case of a laminated body whose entire surface is pressed.

On the other hand, it was found that the laminate subjected to the pressing process by the press device according to the embodiment hardly causes pop-up and has a strong tendency to take out all the sheets one by one.
