Cutting device for paper feed mechanism

Abstract

The present invention provides a cutting device page class. Its along the width of the drawn from the supply roll paper direction to cut off the roll of paper, cut off the page class device includes: transmission path, to pull out of the guide roll; A pair of plate cutting knife, their width wider than paper, along the thickness direction of the conveying path moving paper on both sides of the configuration in the form of across the paper; Base, whose formation is in the face of a pair of side wall and the connection of the wall connected to the wall of hollow structure, on the surface of wall has a cutting knife for cutting knife installed on the surface, the base is set along the thickness direction of the paper is able to move freely, installed in the plane cutting knife; Driving mechanism, which is used to make the base move along the thickness direction of the paper, the base of the cutting tool relative to the is located at the tip of the cutting paper of the front of the press, and make the base of the cutting with a cutting knife to cut off the roll of paper.

Description

technical field [0001] The present invention relates to a device for cutting paper sheets such as interlayer paper used for stacking and packaging glass substrates. Background technique [0002] In recent years, glass substrates for flat panel displays such as liquid crystal displays and plasma displays have been increased in size and thickness. For example, when reaching the 8th generation, the glass substrate called G8 has a size of 2500 mm x 2200 mm and a thickness of about 0.7 mm. [0003] When transporting such glass substrates for flat panel displays, the multiple glass substrates laminated with interlayer paper are stored vertically in a packaging container, or the glass substrates laminated with interlayer paper are stacked horizontally. State It is accommodated in a packaging container, and it conveys with the conveyance equipment in the state accommodated in the said glass substrate in a packaging container. [0004] The interlayer paper sandwiched between the gl...

Problems solved by technology

[0018] Therefore, even if the base member 111 on which the upper blade 100 is attached is made of a thick metal plate with high rigidity, the rigidity (torsional rigidity, bending rigidity) is insufficient.

[0019] For example, during the repeated cutting of interlayer paper, the following problems may occur: the base member 111 is deformed, the meshing of the upper knife 100 and the lower knife 111 is deviated, and the sharpness is deteriorated.

[0020] In addition, since the thickness of the interlayer paper is extremely thin, about 0.08 mm, the distance between the blade edges of the upper knife 100 and the lower knife 101 when cutting the roll paper 112 needs to be maintained at a very small distance of about 0 mm to 0.01 mm. As mentioned above, as the size of the upper blade 100 increases, it becomes difficult to accurately maintain the gap.
