[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated board for producing a corrugated board which is formed by sandwiching a pair of corrugated sheets formed in a corrugated shape with their tops joined and bonded together. The present invention relates to a paper manufacturing method and a corrugated board manufacturing system.

[0002]

2. Description of the Related Art Generally, corrugated paper as shown in FIG. 3 is known (for example, JP-A-1-196).
No. 334 publication). In this corrugated paperboard S, a pair of corrugated sheets W (Wa, Wb) formed in a corrugated shape are bonded together by bonding their tops t to each other, and a flat plate is formed on both outsides of the bonded corrugated sheets Wa, Wb. The flat plate sheets F (Fa, Fb) are bonded together. Conventionally, as a method for manufacturing this corrugated paperboard S, for example, the method disclosed in the above-mentioned JP-A-1-196334 is known. As shown in FIG. 4, the roll paper 1 is fed out, one corrugated sheet Wa is formed by the forming rollers 2 and 3, an adhesive is applied thereto by the adhesive applicator 4, and the roll paper 5 is fed out. And the other corrugated sheet Wb is molded by the molding roller 6 and the molding belt 7, and the one corrugated sheet W formed between the molding roller 2 and the molding belt 7.
a and the other corrugated sheet Wb are sandwiched immediately after the molding, and the tops t of the corrugated sheets W are joined and bonded together, and the corrugated sheet W is conveyed by the molding belt 7 and heated by the heater 8 during the conveyance, and further conveyed. An adhesive is applied to the one corrugated sheet Wa by the adhesive applicator 9 on the way, and further, the roll paper 10 is fed out as one flat plate sheet Fa and adhered to the one corrugated sheet Wa during the transportation. , The other corrugated sheet W
An adhesive is applied to the b by the adhesive applicator 11, and then the roll paper 12 is fed as the other flat sheet Fb and adhered to the other corrugated sheet Wb to obtain a product.

[0003]

By the way, in the manufacture of such a conventional corrugated paperboard S, roll papers 1, 5 are used.
When the sheet is unwound and formed by the forming rollers 2, 3, 6 and the forming belt 7, a difference in tension is inevitably generated between the one corrugated sheet Wa and the other corrugated sheet Wb. And the speed of the molding rollers 2, 3, 6 and the molding belt 7 must be adjusted in a timely manner. In this adjustment, if a difference in tension is generated between the one corrugated sheet Wa and the other corrugated sheet Wb, the product after adhesion may be easily distorted and the quality may be deteriorated, or the roll paper may be lost. In this case, new roll paper is replenished and replenished, but due to the difference in tension between the sheets Wa and Wb, a difference occurs in the amount of roll paper wound on the rolls, causing problems such as poor balance. Do it to eliminate it. Such adjustments and roll paper supply operations are relatively short (several tens of seconds to several minutes).
Although it is a temporary work, the apparatus is temporarily stopped to stop the bonding process of the one corrugated sheet Wa and the other corrugated sheet Wb. Therefore, there is a problem that a loss corresponding to the stop time occurs, and when a large amount of roll paper is processed, the operating rate decreases and the loss becomes extremely large. Therefore, it is desired to perform the adjustment without stopping the bonding process of the one corrugated sheet Wa and the other corrugated sheet Wb. However, if the adjustment is performed without stopping the bonding process in this manner, the conventional manufacturing process Adheres the one corrugated sheet Wa and the other corrugated sheet Wb immediately after molding, so that there is no play in the sheets Wa and Wb. Therefore, if the speed is adjusted too slowly, even if this is temporary, Tension may be applied to the corrugated sheet W more and more, and in this case, the corrugated sheet W is damaged, and the device must be stopped for readjustment. However, there is a problem that the adjustment time becomes long and the adverse effect becomes rather large.

The present invention has been made in view of the above-mentioned problems, and it is possible to perform a temporary sheet speed adjustment work or roll paper without stopping the bonding process of one corrugated sheet and the other corrugated sheet. It is an object of the present invention to provide a corrugated paperboard manufacturing method and a corrugated paperboard manufacturing system in which the loss of downtime is reduced and the operating rate is improved by making it possible to perform the replenishment work of the above.

[0005]

In order to solve such a problem, a corrugated paperboard manufacturing method of the present invention is designed such that a pair of corrugated sheets formed in a corrugated shape are bonded together by joining their tops. In a corrugated paperboard manufacturing method for manufacturing a corrugated paperboard in which flat plate-shaped flatsheets are adhered to both outer sides of the joined corrugated paperboard, in a corrugated paperboard manufacturing method, a roll paper is fed out to form one corrugated papersheet and send it out, Roll paper is fed out and sent out as one flat sheet, one of these sent out corrugated sheets and one flat sheet is adhered to create and carry one side semi-finished product, and roll paper is drawn out and the other corrugated sheet is drawn out. A sheet is formed and sent out, the roll paper is fed out and sent out as the other flat sheet, and the other corrugated sheet and the other flat sheet that are sent out are adhered to each other and the semi-finished product on the other side Transported by creating, as well as hanging over the rod-shaped member of each semi-finished product in the course conveyance path of these one-side workpiece and the other side semiconductive product, suspended below the rod-like member
The semi-finished product on one side and the semi-finished product on the other side are loosened by the receiving surface
Receiving as to, whereas the corrugated sheets together side blank and the other side workpiece is opposed, and configured to adhere by bonding the top portions of these corrugated sheet.

As a result, corrugated paper is manufactured one after another, but in the middle of this manufacturing, a difference in tension is inevitably generated between the one corrugated sheet and the other corrugated sheet. Therefore, the sheet feeding speed can be adjusted in a timely manner. I have to do it. Alternatively, when the roll paper runs out, new roll paper is added to replenish. In this adjustment, if a difference in tension occurs between the one corrugated sheet and the other corrugated sheet, distortion may easily occur in the product after adhesion and the quality may deteriorate, or if the roll paper runs out. In this case, new roll paper is replenished and replenished, but this is performed in order to solve a problem such as a difference in the amount of use of the roll paper due to a difference in sheet tension, resulting in poor balance. Such adjustments and roll paper replenishment work can be performed without stopping the bonding process between one corrugated sheet of one side semi-finished product and the other corrugated sheet of the other side semi-finished product. In this case, for example, because the speed was too slow when adjusting the semi-finished product on one side,
Even if the transport of the semi-finished product on one side is temporarily delayed, there is a loose play left and right sandwiching the rod-shaped members of the semi-finished product on one side and the semi-finished product on the other side suspended by the rod-shaped member. Can be absorbed, and a situation in which a trouble occurs in the bonding process is prevented.

If necessary, a plurality of the rod-shaped members are used to hang the one-side semi-finished product and the other-side semi-finished product in a plurality of stages. Since there are a plurality of stages, the amount of play increases, and therefore, it is possible to reliably prevent any trouble in the bonding process during temporary adjustment. If necessary, the rod-shaped member of the semi-finished product on the one side and the rod-shaped member of the semi-finished product on the other side are provided in parallel so that the corrugated sheets of the semi-finished product on the one side and the semi-finished product on the other side face each other. There is. Since the corrugated sheets face each other in advance, they can be joined simply by performing phase matching in the bonding process, and the efficiency becomes higher accordingly.

Further, in the corrugated paperboard manufacturing system of the present invention for solving such a problem, a pair of corrugated sheets formed in a corrugated shape are bonded together by bonding their tops to each other and are bonded together. In a corrugated paperboard manufacturing system that manufactures corrugated paperboard in which flat plate-shaped flat sheets are adhered to both outer sides of a corrugated paperboard, one side corrugated paperboard molding in which a roll paper is unrolled and one corrugated paperboard is formed and sent out. Machine, one side flat sheet feeding machine that feeds roll paper and sends it out as one flat sheet, and one corrugated sheet and one flat sheet that are sent out are bonded and one side semi-finished product is created and conveyed One side semi-finished product making machine, the other side corrugated sheet forming machine for feeding the roll paper to form the other corrugated sheet for delivery, and the other side corrugated sheet forming machine for delivering the roll paper The other side flat sheet delivery machine for delivering as a plate sheet, the other side semi-finished product producing machine for producing the other side semi-finished product by adhering the other corrugated sheet and the other flat sheet to be delivered, and the above A rod-shaped member that hangs by hanging one side semi-finished product and the other side semi-finished product from the one side semi-finished product making machine and the other side semi-finished product making machine in the middle of the conveying path.
The semi-finished product on one side and the semi-finished product on the other side, which are suspended and conveyed, are provided with a bonding machine that makes these corrugated sheets face each other and joins the tops of the corrugated sheets by bonding them.

As a result, corrugated paper is manufactured one by one, but during the manufacturing process, a difference in tension is inevitably generated between the one corrugated sheet and the other corrugated sheet. Therefore, the sheet feeding speed can be adjusted in a timely manner. I have to do it. Alternatively, when the roll paper runs out, new roll paper is added to replenish. In this adjustment, if a difference in tension occurs between the one corrugated sheet and the other corrugated sheet, distortion may easily occur in the product after adhesion and the quality may deteriorate, or if the roll paper runs out. In this case, new roll paper is replenished and replenished, but this is performed in order to solve a problem such as a difference in the amount of use of the roll paper due to a difference in sheet tension, resulting in poor balance. Such adjustments and roll paper replenishment work can be performed without stopping the bonding process between one corrugated sheet of one side semi-finished product and the other corrugated sheet of the other side semi-finished product. In this case, for example, because the speed was too slow when adjusting the semi-finished product on one side,
Even if the transport of the semi-finished product on one side is temporarily delayed, there is a loose play left and right sandwiching the rod-shaped members of the semi-finished product on one side and the semi-finished product on the other side suspended by the rod-shaped member.
