いる。One of the most common conventional gypsum board forming methods is the roll board forming method. This roll-type board forming method involves interposing slurry-like gypsum board raw materials between an upper paper and a lower wood, and then rolling them onto a pair of upper and lower forming rolls whose spacing is adjusted according to the thickness of the board to be manufactured. It is made into a green board through which it is cut into fixed lengths after it hardens. In this case, it has been found that the flatness of the gypsum board is greatly affected by the uneven rotation of the forming roll, the accuracy of its bearings, the eccentricity of the forming roll, the amount of supply of slurry-like gypsum board raw material, its softness, etc. ing.

詳細に説明する。However, if the gypsum board raw material contains solids that are thicker than the board, the forming plate v-) does not have the crushing ability of a forming roll at all, so it gets caught on the forming plate and causes the upper paper and lower paper to be crushed. There was a drawback that tearing the paper caused the production line to stop and the product yield to decrease.The present invention solves the drawbacks of the conventional method when manufacturing the above-mentioned gypsum hoard. The purpose of the present invention is to provide a method for producing thick and uniform gypsum board with good flatness at a high yield by skillfully combining the advantages of the forming roll method and the forming plate method. ◎ The configuration of the first gypsum board size and shape control method of the present invention that achieves this objective is to interpose slurry-like gypsum board raw material between the top paper and the bottom paper, and to separate these from above and below. After making a green board of a predetermined thickness by passing it through a pair of forming rolls, this clean board is passed between a pair of upper and lower correction plates installed behind the forming rolls to improve the flatness of the green board. This feature is characterized in that it allows the user to In addition, in the second method of controlling the size and shape of a gypsum board according to the present invention, a slurry-like gypsum board raw material is interposed between the top paper and the bottom paper, and these are passed through a pair of upper and lower forming rolls. After passing this clean board through a pair of earthwork correction plates fixed at a certain distance behind the forming roll, the resistance applied to the correction plate is kept within a certain range. This is characterized by the fact that the IJ-board has a constant thickness.Hereinafter, the main parts of an embodiment of the method for controlling the size and shape of a gypsum hoard according to the present invention will be explained. This will be explained in detail with reference to FIG. 1 and FIG. 2, which shows a means for detecting the thickness of a green board.

整を行なっている。Reference numeral 15 is a drive motor 20 whose operation is controlled by a control device (not shown), which allows it to move toward and away from the lower forming roll 14 at will even during the manufacture of gypsum board.
Further, the lower front part of the upper correction plate 19 is opened in a tapered shape to prevent the upper paper 11 from being pulled by the correction plate 19 and damaged. In this embodiment, in order to detect the state of contact between the correction plates 18 and 19 and the green hoard 16, the full air supply bag passage 21 connected to the gust supply source (not shown) passes through the upper correction plate 19i. Further, a pressure gauge 22 is attached to the gas supply path 21, which branches off from the gas supply path 21 and detects the nitrogen pressure within the air supply path 21. The aforementioned control device controls the operation of the drive motor 20 in response to the signal from the pressure gauge 22 so that this value becomes a smoothly set value. While measuring the total back pressure by spraying nitrogen gas from the air supply path 21 onto the surface of the green hoard 16, by adjusting the spacing between the forming rolls 14 and 15, this back pressure can be kept within a certain set value. If there are large fluctuations in air back pressure, in addition to adjusting the spacing of the forming rolls 14° and 150°, the supply amount of slurry-like stone/U-board raw material 13 and its softness may be adjusted. Alternatively, the conveyance speed of the forming belt conveyor 17 in which the forming rolls 14 and 15 rotate synchronously may be adjusted alone or in combination. In this way, in this embodiment, compressed nitrogen is sent between the upper correction play 19 and the clean board 16 to detect the resistance applied to the correction play 18.19 or thereafter. On the other hand, changes in the supply amount and properties of the slurry-like gypsum board raw material 13, changes in the load applied to the correction plates 18 and 19, changes in the gap between the clean board 17 and the correction plate 19, and even the thickness of the formed board A device for detecting changes, etc. may be installed to indirectly detect the resistance applied to the correction play) 18.19 based on the supply amount f properties of this gypsum board raw material 13. Specifically, for example, the resistance applied to the forming roll 14.15 Or detect the fluctuation of the reaction force acting on the correction plate 18.19 with a load cell or the like, or detect the supply and storage amount of the slurry-like stone board raw material 13 in front of the forming rolls 14 and 15. By adjusting the distance between the forming rolls 14.15, the gypsum board raw material 13, the glue 11 or its softness, or the conveyance speed of the forming belt conveyor 17, either alone or in combination with each other, the resistance to be applied to (18.19) can be adjusted. Keep it within a certain range.According to an untrue experience, when the target value of the thickness of the stone electric board as a product is aO mm, the reading of the pressure gauge 22 is 100tnnA.
7. By maintaining the range of , ~130+uA,g, the thickness could be kept within the range of 96 mm to 104 mm.If the pressure is lower than this, the upper correction plate 19 and the clean board 16 A gap is formed between the parts, and the thickness increases.
Along with this, its flatness also decreases. Also, 130 tanA
, if the pressure is higher than g, the thickness will be less than the target value A'< if
As soon as we met, it was discovered that gypsum board raw material 13 was leaking from the lean hoard 160 double-ended sword.
Furthermore, the variation in thickness of a single piece of gypsum board in the width direction (direction perpendicular to the plane of the paper in the figure) when using only conventional forming rolls was calculated from α09 mm〃) to 00.
It was possible to reduce the height by 1 to 4 mm or less @ Therefore, the vertical position W of the upper correction plate 19 was fixed in accordance with the thickness of the product stone fII' hoard, and the pressure H122 at this time was fixed. After entering the allowable range into the control device in advance, compressed air is fed from the air supply path 21 between the green board 16 and the upper correction plate 19, and the forming rolls 14 and 15 are driven. The green board 16 is formed by rotation. At this time, the solids mixed into the slurry-like gypsum board raw material 13 are crushed and compressed by the forming rolls IIi (IIi), so the solids are caught in the correction play 18 and 19 and the upper paper 11 or the lower paper 12 is There is no chance of it being damaged. green board 16
passes between the correction plates 18 and 19, its flatness is corrected so that the upper paper 11 becomes parallel to the lower paper 12, but the drive motor 2 is operated so that the detected value of the pressure gauge 22 is always constant.
The molding roll 151 with 0 on the upper side is constantly moved up and down to adjust the thickness of the sea bream.

ボードを製造することができる。In this embodiment, the upper forming roll 15i is raised and lowered by detecting the contact state between the green board 16 and the correction plate 19, but the supply amount and properties of the slurry-like gypsum board raw material 13 are almost constant. In this case, you can adjust the thickness and flatness by simply setting the spacing of the damp forming rolls (14° and 15) and the spacing of correction plays (18 and 19) according to the thickness of the gypsum board that will be the product. It is possible to manufacture high-quality stone and stone boards.

石膏ボードを連続的に大量生産することができるＯAs described above, according to the gypsum board size and shape control method of the present invention, since the correction plate roller is arranged behind the forming roll, solids mixed in the slurry-like gypsum board raw material are caught and become the top paper or the bottom paper. There is no risk of damage to the green board, and the flatness of the green board is greatly improved by the correction plate. In addition, the spacing between the forming rolls is adjusted so that the resistance applied to the correction plate is within a certain range, making it possible to make the thickness of the greenboard uniform, resulting in uniform quality. It is possible to continuously mass-produce high-quality gypsum board.
