[Industrial application]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin sheet paper conveying device, and more particularly, to a thin sheet paper straight-moving corrugating device that allows straight movement of the sheet at high speed without distortion.

[0002]

[Prior Art]

 Conventionally, in plain sheet paper, a winding paper wound into a predetermined length by a coil is fed out by a feeder and cut by a cutter into a predetermined length.

Then, the sheet of paper cut into a predetermined length with a cutter is conveyed to a sheet laminating apparatus while being overlapped on a conveying conveyor, and the sheet is laminated every predetermined number of sheets. The equipment is piled up and loaded on a pallet for unloading.

[0004]

[Problems to be solved by the device]

 In recent years, due to the improvement in productivity, the processing speed of the apparatus has been increased, the speed of cutter speed has been increased, and the speed of conveyance of sheet paper has also been increased accordingly.

However, when the conveying speed of the thin sheet of paper becomes high speed, the wind pressure applied to the sheet of paper becomes large at the overlap portion and the sheet stacking portion, so that -The leading edge of the sheet does not go straight and is easily bent, so that when the sheet is overwrapped or the sheet is stacked by the sheet stacking device, the sheet is stacked. -The end faces of the sheet paper were uneven, the sheet paper was damaged, and the sheet paper jammed up, causing the machine to stop.

Therefore, recently, a press roll is attached to the upper side of the conveyor belt at a constant interval, and the lower part of the press roller is inserted between the conveyor belts to form a corrugated uneven surface on the sheet of paper. It is known that the sheet is conveyed so that the sheet is not distorted by increasing the rigidity of the sheet.

However, in the above-mentioned sheet, since the sheet of paper is rapidly pressed by the pressing roll portion to form the corrugated uneven surface, there is a drawback that the sheet of paper is easily wrinkled.

[0008]

[Means for Solving the Problems]

 The present invention has been made in view of the above points, and in order to solve the above-mentioned problems, a roll of paper having a predetermined length is cut by cutting a paper roll conveyed at high speed into a predetermined length. -In a thin sheet paper conveying device that conveys sheet paper to the rear, an endless corrugation of a predetermined length is formed on a plurality of conveyor belts arranged side by side at a predetermined interval in the width direction of the sheet paper. Belts are arranged so as to face each other, and the sheet of paper is formed so as to run between the conveyor belt and the corrugating belt, and the endless corrugating belt is gradually conveyed toward the rear side. It is another object of the present invention to provide a straight corrugating device for straight-moving thin sheet paper, which is slanted so as to be inserted between the belts and arranged between the belts.

[0009]

[Action]

 According to the present invention, when a continuous sheet of paper is cut into a predetermined length and sent to a corrugating device, the sheet of paper is separated into a conveyor belt and an endless corrugated belt of a predetermined length. Is inserted between. Then, the sheet of paper advances along the corrugated belts that are slanted between the conveyor belts, so that the corrugated uneven surface is formed at a constant interval in the width direction of the sheet of paper. It is formed so as to gradually increase in the length direction of the paper. Therefore, the sheet is less likely to be wrinkled, and the rigidity of the sheet is improved to improve the straightness of the front end, so that the sheet can be conveyed straight without distortion, and the end surface of the sheet is uneven. The sheet can be piled up neatly on the sheet laminating device without damaging the sheet by breaking the end face. Also, the sheets will not jam and the machine will not stop.
