【発明の詳細な説明】 〔技術分野〕 本発明はセメント板、石膏板、ケイ酸カルシウム板など
の建築用生板の厚み調整方法に関する。TECHNICAL FIELD The present invention relates to a method for adjusting the thickness of a green board for construction such as a cement board, a gypsum board, and a calcium silicate board.

の調整によって前工程の厚みのコントロールをするよう
にするのが一般的であった。The conventional method for adjusting the thickness of the green plate for construction is to convey the thickness of the green plate for construction mainly made of cement, gypsum, calcium silicate, etc., which is formed by a Fourdrinier or round-net paper machine, at one to three places. It was general to measure the thickness by a contact type thickness meter using a strain gauge installed above and control the thickness change in the previous step by adjusting the compounding amount and the agitator.

クする方法が常法であった。However, with such thickness adjustment, it is difficult to measure the thickness distribution in the width direction of the green building plate finely, and it is difficult to manufacture a green building plate of uniform thickness. Therefore, the method of measuring the thickness of the building board after hardening and feeding it back was the usual method.

することのできる建築用生板の厚み調整方法にある。The present invention has been made in view of the background art described above, and an object thereof is to continuously detect a thickness variation in the width direction of a green building board by a non-contact type sensor and detect this thickness variation in a vacuum of a suction box. It is a method of adjusting the thickness of a green building plate that can produce a green building plate of uniform thickness by feeding back the adjustment of the degree.
以下、本発明の一実施例に係る図面に基づいて説明す

クス４の真空度の調整にフィードバックするようにして
厚み調整を行なうようにしたものである。In the figure, the thickness in the right-angled width direction of the green building board 2 mainly composed of cement, gypsum and calcium silicate, which is continuously formed on the belt conveyor 1 by the paper making machine, with respect to the traveling direction of the belt conveyor 1. It is continuously detected by a laser-type non-contact type sensor 3 that can freely reciprocate in an oblique direction, and the detected variation in the thickness in the width direction is divided in the width direction provided on the papermaking machine or at the exit of the papermaking machine. The thickness is adjusted by feeding back to the adjustment of the vacuum degree of the suction box 4.

前工程にフィードバックされる。Therefore, the thickness of the green building plate 2 in the width direction at right angles is continuously detected by the non-contact type sensor 3, so that the thickness variation in the width direction can be measured by the reflection distance of the laser. Then, the thickness variation in the width direction is fed back to the previous process so that the thickness is adjusted by the difference in suction force by adjusting the vacuum degree of the suction box 4 divided in the width direction.

低下にもつながる方法である。As described above, the present invention continuously detects the thickness in the right-angle width direction of the green building board continuously formed on the belt conveyor with the non-contact type sensor, and detects the thickness in the width direction. The thickness in the width direction of the plate is different from the conventional method because the thickness is adjusted by feeding back to the adjustment of the vacuum degree of the suction box divided in the width direction provided on the paper making machine or at the exit of the paper making machine. The variation can be measured finely, and the measured variation can be adjusted by the vacuum degree of the suction box to produce a building board having a uniform thickness. Further, it is unnecessary to adjust the blending amount and the agitator. Further, it is not a method of measuring the thickness of the building board after curing and feeding back this thickness, so that the speed of feedback is fast and it leads to a reduction in the defective rate.
