Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is formed into predetermined shapes with different thicknesses and sizes,
This invention relates to an automatic paper feeding method and apparatus for continuously laminating two sheets of base paper that are not uniform in thickness and have a step difference.

Conventional technology When two sheets of base paper with different thicknesses and sizes are pasted together, for example, a paper bag for collecting vehicles (vacuum filter bag) used in a vacuum cleaner is suctioned on one side as shown in Figure S. A paper bag with a mouth (1) and folded flat (
21, and a mount 14) made of cardboard with a hole (3) that matches the suction port (1) is attached to the surface of the paper bag for reinforcement and for installation in the model around the suction port. It is extremely difficult to manufacture one paper bag and form and attach the backing paper using a single automatic bag making machine, and the equipment costs are enormous. It is best to use the method of combining paper bags and paper mounts, but the paper thickness and size of the paper bag and mount are different, and the thickness is not uniform and there are steps, so problems with transportation are unavoidable. There was a problem with automatic paper feeding for alignment, making it difficult to achieve high efficiency automation.

Problems to be Solved by the Invention The present invention easily overcomes these drawbacks by automatically laminating two sheets of base paper having different thicknesses and sizes in a fixed position one after the other while automatically folding them together. The object of the present invention is to provide an automatic paper feeding method and device that can perform the following steps.

DETAILED DESCRIPTION OF THE INVENTION As described above, according to the present invention, the base papers, which are fed out intermittently with glue applied to their lower surfaces, are sequentially placed on symmetrical support rods that protrude radially around both sides of a rotary drum. The disks are then rotated and placed one by one between special rotary disks that are symmetrically arranged and have a spiral rod formed on the upper surface of the lower periphery of the disk, with the glued side facing up. Each time, another base paper is fed in from the other side with a gap left above it, and as the spiral rod of the special rotary disk rotates, the glued base paper is raised, and the upper base paper is placed in the local part of the spiral rod. The rise of the paper is temporarily suppressed by a horizontal restraining rod provided on the top of the paper, and both base papers are polymerized and pasted together, and then stacked one after another on the top surface of the spiral rod, making it one quality paper.

Two sheets of base paper of different sizes and thicknesses can be easily and easily polymerized and bonded automatically without any trouble. It is possible to easily automate the polymerization and pasting of base paper (paper bags, mounts attached to them, paper patterns, etc.), which is useful for mass production and cost reduction. In addition, by using an intermittent rotating rotary cylinder with radial support rods as described above to properly dry the glued surface,
It has the characteristics that the drying process does not take up much space and the device can be made compact.
