Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to a single facer for manufacturing single-sided corrugated board.

(!) Problems to be solved by the conventional technology and the invention The conventional single facer can
Only one-sided corrugated cardboard of either type 111 of C or E flute could be manufactured.

The present invention provides a single facer that is capable of manufacturing single-sided corrugated cardboard having a plurality of flutes with one facer.

(3) Means for solving the problem The single facer of the present invention consists of an upper roll 11 and a lower roll 12 that meshes with the upper roll 11 and forms corrugated steps on the core paper M that is being fed. a plurality of corrugating roll devices 10, a rotating device 20 in which the plurality of corrugating roll devices 10 are arranged so as to be able to rotate, and a corrugating roller on the lower corrugating roll 12 of any of the corrugating roll devices 10 While applying glue to the corrugated top F of the core paper M, the corrugating roll device 1
One gluing device 30 is movable within a range where it does not interfere with the rotation of the corrugating roll device 10, and the liner paper that is sent is arranged so as to be able to contact each of the lower rolls 12 of the corrugating roll device 10. One pressure roll 40 to be laminated with the glued core paper M sent from the lower roll 12
It is equipped with the following.

In the present invention, the corrugating roll device IO includes an upper corrugating roll 11
and the lower roll 12 individually or in conjunction with the pressure roll 3
A moving device 13 is provided for each axis (not shown) of the upper roll 11 and the lower roll 12 so that they can be pressed together or separated. The rotating device 20 also includes a rotating frame 21 to which a plurality of corrugated roll devices 10 are attached, and a rotating frame 2
1 and a starting device 22 for rotating the motor. The gluing device 30 is a glue tank 31. It is equipped with a glue roll 32°, a doctor roll 33 and a doctor knife 34.

(4) Actions and effects of the invention.

Now, if the corrugating roll device 10(A) is used to make the A flute, and the corrugating roll device 10@ is used to create the B flute and the B flute (as well), then in order to manufacture the A flute single-sided corrugated board S, the following steps are required: After operating the rotation device 20 to rotate the corrugating roll device 10 (c) to the predetermined position X, the liner paper wound around the pressure roll 40 and the lower corrugating roll 12 (c) Core paper M fed out and glued
The lower roll 12 (c) is brought into pressure contact with the pressure roll 4GFC so that the two can be bonded together. Next, the gluing device 30, which was in a position where it does not interfere with the rotation of the corrugating roll device IO, is moved to position a, and the glue roll 32 is placed on the lower reel 12 (c) of the core paper M that has been wound. Adjust so that it touches the top of the step F. The lower roll 12@ of the corrugating roll device 10@ is kept separated from the pressure roll 40.

After doing this, if the lower roll 12 (c) of the corrugating roll device lO (c), the glue roll 32 of the gluing device 30, and the pressure roller 40 are started and rotated, the single-sided corrugated cardboard S of the A flute will be continuous. ξ is produced as follows. To manufacture single-sided corrugated board with B flute, the gluing device 30 is
After separating the lower roll 12 (IQ) of the corrugating roll device 1G (c) from the pressure roll 40,
Start the rotating device f120 and move the corrugated roll device 10 (c) to 2
B-flute single-sided corrugated board can be manufactured using the same operation as when manufacturing single-sided corrugated poles using a corrugating roll device.

Therefore, according to the present invention, a single single facer can produce a plurality of different flutes of chiseled corrugated cardboard.

(6) Embodiment 10 (c) is a corrugating roll device that is made up of an upper roll 11 (8) and a lower roll 12 (c) that meshes with the upper roll 11 (8), and that creates a free-flow of the A flute, and is moved by a pair of air cylinders. ,
A moving device 13 (c) is provided for pressing the lower roll 12 (c) against or separating from the pressure roll 40.

10@ is a corrugating roll device consisting of an upper roll 11@ and a lower roll 12@ that meshes with the upper roll 11@ and which creates a free-flow of the B flute. Move each journal receiver 111@ and 112@ and lower roll 12@
A moving device 13@ is provided to press the pressure roll 40 into contact with or release it from the pressure roll 40.

20 is a rotating device, and corrugated roll devices 10 (c) and 10
@ and single-sided cardboard guide rolls 211 (c) and 21
A rotation frame 21 with a pinion 22 attached thereto, and a fan-shaped gear 210 carved in the rotation frame 21.
1 is provided. 30 is
A roller 311 moving on a track 312 is provided and iζ
A glue tank 31 provided with a preheater 61 and a core paper guide roll 62. Glue roll 32. This gluing device is equipped with a doctor roll 33 and a doctor knife 34, respectively. 4
0 is a normal pressure roll with a large outer diameter, which has a large heating effect and is convenient for adhering liner paper to core paper.
