Description

[Detailed explanation of the idea] The present invention relates to an apparatus for manufacturing corrugated cardboard.

Recently, the demand for corrugated cardboard has increased, but there has been no equipment that can continuously and efficiently manufacture this corrugated cardboard.

The present invention provides a gluing device for gluing the crests of the corrugations of the single-sided cardboard being conveyed, and the gluing device is installed at a lower position in the conveying direction than the gluing device, and the one-sided corrugated cardboard and the other paper are glued together by a roller guide. proposes a corrugated cardboard manufacturing apparatus in which an overlapping part is formed through the crests of the waves, and a forming device consisting of a pair of corrugated gears that mesh with each other is provided in this overlapping part. , it is possible to continuously form corrugated cardboard while supplying one-sided cardboard and other paper (liner paper, etc.).

An embodiment of the present invention will be described below with reference to FIG.

Reference numeral 1 is a single-sided corrugated board, and consists of an upper liner plate 2 and a corrugated plate 3 attached to the lower surface of the liner plate 2.

Reference numeral 4 denotes a gluing device disposed below the transport path of the single-sided cardboard 1, which glues the corrugated crests of the corrugated sheet 3 via its gluing roll 5.

For the gluing, a guide roller 6 is provided at a lower position in the conveyance direction than the device 4, and a liner paper (an example of other paper) 7 is supplied to the wave crest side via this guide roller 6. Therefore, the single-sided cardboard 1 and the liner paper 7 are overlapped by the roller guide, and the pasting forms an overlapping part through the wave crests.

In this overlapping part, a pair of upper and lower wave gears (trochoid gears) 8
, 9 is provided.

Here, the double-wave gears 8 and 9 are arranged to mesh with each other with a certain gap and rotate in opposite directions.

11 shows the manufactured corrugated cardboard.

While the single-sided cardboard 1 is being transported, the crests of the corrugated sheets 3 are pasted with a paste roll 5.

While the liner paper 7 is supplied below the corrugated sheet 3 via the guide roller 6, the single-sided cardboard 1 and the liner paper 7 are supplied to the forming device 10 side of the overlapping part.

In this forming device 10, the single-sided cardboard 1 and the liner paper 7 are overlapped with each other and are held in the gap between the peaks and valleys of the double-wave gears 8 and 9 that mesh with each other.
Thus, the corrugated cardboard 11 is formed and at the same time the corrugated crest and the liner paper 7 are attached.

FIG. 2 shows another embodiment in which another single-sided cardboard 12 can be superposed on the corrugated cardboard (separately made of other paper) 11.

That is, gluing is performed on the wave crests of another single-sided cardboard 12 by the gluing roll 14 of the device 13.

Then, this other one-sided cardboard 12 is placed on the guide roll 15.
The corrugated cardboard box 12 is fed into the lower part of the corrugated cardboard box 11 through a liquid acid forming device 18 consisting of a pair of corrugated gears 16 and 17 to perform clamp forming. .

As a result, a polymerized corrugated cardboard 19 can be formed.

According to the present invention having the above configuration, corrugated cardboard can be continuously and efficiently manufactured while supplying one-sided cardboard and paper on the other side.
