Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for producing single-sided corrugated cardboard, and more particularly to a method for producing two strips of single-sided corrugated cardboard at the same time using a single device.

Conventionally, the manufacturing method and apparatus for one-sided corrugated board include a pair of stepped rollers for corrugating one paper, a pressure roller for laminating a liner to the corrugated one, and other gluing rollers. It is manufactured using a single-sided corrugated board manufacturing device commonly called a single facer, which includes incidental equipment such as a single facer.

Naturally, the single-faced corrugated pole produced by a single device is only one strip, and in order to efficiently produce two, for example, five layers of corrugated board, two of the single facers are required. Furthermore, in order to increase the production volume 7 of single-faced corrugated poles, it is inevitably necessary to increase the number of single facers, and an increase in equipment costs is unavoidable.

In view of the current situation, the present invention provides a method for manufacturing single-sided corrugated board that can reduce equipment costs and improve productivity.

The present invention is characterized in that two liners are passed through a pair of stepped O-rules, so that each liner is processed into a stepped liner, and the stepped liner is formed on the outer surface of two liners that are stacked separately. This invention relates to a method for producing single-sided corrugated board, characterized in that two strips of single-sided corrugated board are simultaneously produced by laminating the same number of cores.

The present invention will be explained below based on two most preferred embodiments. In Figure 1, A is a stepped circle, and the upper stage O
It is made up of a lower O-ru 1a and a lower O-ru 1b.One O-ru has many steps engraved on the curved surface, and the two O-ru interlock and fit together.

The number of cores inserted between them is 2, which is corrugated and stepped base paper 2.
Process to 1. Similarly, B also has a stepped 0-ru, and the upper stage O
The 2-car 0-ru consists of a 0-ru 3a and a lower 0-ru 5b.The 2-car 0-ru has steps of the same pitch and ν as the upper and lower corrugated rolls 1m and 1b of the stepped O-ru A on the circumferential surface. By the bite of
The number of cores inserted between them is 4 and processed into 2 steps 41. 5.5 is the gluing device di for gluing the tops of the stepped base papers 2/ and 4/, and 6.7 is the superimposed 2
It is a liner. The stepped O-rues A and B have built-in steam heating means (not shown), and each of the lower O-rues 1b and 3b also has a rotary middle stepped core number 2 on a part of its circumferential surface. A suction mechanism (N not shown) is attached to prevent separation of ', 4'.

Note that the lower O-rules 1b and 3b are disposed oppositely in the same axial direction, and the phases of the two rolls do not mesh with each other.
In other words, a drive mechanism (not shown) is attached that rotates the two wheels synchronously in two rotational directions while maintaining the position in which the step tops of both wheels are in contact with each other. 8 and 8' are the stepped base paper 2. This is a two-striped single-sided corrugated board manufactured by laminating /, 4/ and liner 6.7.

Now, in this example, 1 yen 2.4 is each stepped O.
-Upper and lower stage O-ru 1m, 1b, 5m, which constitutes A and B,
After being bitten between 3b and processed into a corrugated stepped 1 roll 2/, 4/, it is transferred as the lower rolls 1b, 3b rotate while being adsorbed to the surfaces of the lower rolls ib, sb, respectively. The glue is glued to the top of the tier by the gluing devices 5, 5 and inserted into the lower 0-rules 1b, 3b. The combined two liners 6.7 are the stepped base paper 21, 4/
The stepped base paper 4' and the liner 7 are sandwiched between the stepped base paper 4' and the liner 7, and are pressed together at the tops of the lower O-ru 1b and the lower O-ru 3b. are pasted together to form single-sided corrugated cardboard boxes 8 and 8', respectively, and are sent out.

As is clear from the above description, according to the present invention, two lines of liner can be formed by simply supplying two lines of liner between each of the two lines of corrugated base paper which are stacked in an upper and lower pair. Since single-sided corrugated cardboard can be manufactured efficiently at the same time, there is no need for the important and expensive pressure control of the conventional single facer, which not only simplifies the mechanism but also simplifies the manufacturing process, increasing the productivity of single-sided corrugated cardboard. can be improved.
