Description

[Detailed Description of the Invention] [Industrial Field of Application of the Invention] The present invention provides a paper-making method that is formed into a predetermined length by a paper-making method such as a circular wire method or a fourdrinier method, and has a smooth surface and a feather-like uneven surface on the back surface. The present invention relates to an apparatus for producing inorganic paper-made boards, in which uncured inorganic paper-made boards are inverted and stacked every other sheet.

[Conventional technology]

When manufacturing an inorganic paper board using a paper making method such as a circular wire method or a Fourdrinier method, as shown in FIG. After forming the uncured inorganic paper board 1, the unhardened inorganic paper board 1 on the making roll 2 is cut, for example, at one location using a cutter (not shown) attached to the making roll 2 to determine the circumference of the making roll 2. An uncured inorganic paper board 1 having a length approximately equal to is obtained, and an unhardened inorganic paper board 1 cut into a predetermined length in this way.
is transferred from between the making roll 2 and the bottom roll 3 onto the conveyor 4, and the transferred uncured inorganic paperboard 1 is cut into two equal parts in the length direction by the cutter 5 on the conveyor 4. The separated uncured inorganic paperboards 1', 1' are conveyed to the conveyor 4.
and another auxiliary conveyor 6 connected in series thereto.
about 50 sheets are laminated as a unit in the laminating section 7, and then the inorganic paper sheets 1',
1',... are cured and made into a product.

Therefore, the uncured inorganic paper board 1 or 1' is
Before being laminated in the lamination section 7, the back surface is a feather-like uneven surface, but the surface is smooth because it comes into contact with the surface of the making roll 2 when it is wound around the making roll 2 and formed. It's summery.

[Problem that the invention seeks to solve]

However, uncured inorganic paperboards 1′, 1′,
When they are stacked in the stacking section 7, they are stacked with their front and back surfaces facing in the same direction, as shown in FIG.
There is a problem in that one surface of 1' comes into pressure contact with the back surface of the other, and the smoothness of one surface is significantly impaired by the influence of the uneven surface of the other.

Conventionally, in order to solve this problem, it has been necessary to smooth the feather-like uneven surface on the back surface using a press before laminating the uncured inorganic paper sheets 1'.

[Means for solving problems]

The present invention solves the above problems without using a press by inverting every other cut uncured inorganic paperboard and stacking them.

〔Example〕

Hereinafter, the inorganic paper plate manufacturing apparatus of the present invention will be explained as follows.
An example shown in the figure will be described.

In Fig. 1, 2 is a making roll, and 3 is a roll with a cutter, which are constructed in the same way as conventional equipment. After the papermaking slurry is continuously wound around the making roll 2 about 5 times to form an uncured inorganic paperboard 1 on the surface of the making roll 2, the uncured inorganic paper plate 1 on the making roll 2 is cut with a cutter roll 3 below the making roll 2. The hardened inorganic paper board 1 can be cut into a predetermined length. Also, 6 is an auxiliary conveyor, 7 is a stacking section,
These devices are also constructed in the same way as conventional devices.

Therefore, in the inorganic paper plate manufacturing apparatus of the present invention, the conveyor 4 in the conventional apparatus is replaced with
It consists of a reversible first conveyor 4a provided on the side of the making roll 2, and a second conveyor 4b connected in series to the first conveyor 4a and provided on the side of the laminated layer 7. In the apparatus described above, the cutter 5 is provided between the first conveyor 4a and the second conveyor 4b, and the cutter 5 is provided between the first conveyor 4a and the second conveyor 4b.
A third conveyor 8 is placed below the starting end of the third conveyor 8.
It is provided so as to protrude toward the making roll 2 side from the starting end of the conveyor 4b.

[Effect]

Since the inorganic paper board manufacturing apparatus of the present invention is configured as described above, the uncured inorganic paper board is cut into a predetermined length by a cutter (not shown) attached to the making roll 2 as described above. 1 is
It moves from between the making roll 2 and the bottom roll 3 onto the first conveyor 4a and the second conveyor 4b which rotate normally. The transferred uncured inorganic paperboard 1 is divided into two equal parts by a cutter 5 between the first conveyor 4a and the second conveyor 4b. One of the uncured inorganic paperboards 1b on the second conveyor 4b, which is divided into two halves, is conveyed to the stacking section 7 via the auxiliary conveyor 6 by normal rotation of the second conveyor 4b. Further, by reversing the first conveyor 4a, the other uncured inorganic paper plate 1a on the first conveyor 4a, which is divided into two halves, is bent as shown in the figure and placed on the third conveyor 8 with both front and back sides. is transferred in a reversed state, and is conveyed to the stacking section 7 via the auxiliary conveyor 6 by the forward rotation of the third conveyor 8. Therefore, in the lamination section 7, as shown in FIG. 2, the uncured inorganic paper plates 1a, 1b, . . . are inverted every other sheet and stacked.

In the inorganic paper board manufacturing apparatus of the present invention, for example, even if the starting end of the third conveyor 8 does not protrude beyond the starting end of the first conveyor 4a, the uncured inorganic paper board 1b can be placed on the starting end side of the third conveyor 8. If a guide device (not shown) is provided to bend the belt and guide it from the first conveyor 4a to the third conveyor 8, the same effect as that of the above embodiment can be obtained.

〔Effect of the invention〕

As described above, the inorganic paper board manufacturing apparatus of the present invention can stack cut uncured inorganic paper boards by reversing every other sheet, and when laminating, one of the adjacent unhardened inorganic paper boards can be stacked. Since the surfaces can be brought into pressure contact with each other or the back surfaces without having to bring the smooth surface into contact with the uneven back surface of the other, the smoothness of the surface of the uncured inorganic paperboard can be maintained without using a press. It has a tremendous effect.
