At this time, I know that there is a base material,
Since the gypsum board covers it, it is difficult to know the exact position, which hinders the work. Therefore, every time it was installed, the vertical and horizontal positioning lines were put in by marking.

[0003]

However, when the scribing is done, the gypsum board is always carried out one by one at the working site, so that the work environment is narrow and complicated, and extra labor and time are required. An outline of the manufacturing process of the gypsum board will be described with reference to FIG. 1. Raw material preparation process for gypsum board (a) (1) Crush natural gypsum and by-product gypsum and burn in a kiln 15
Bake at 0 ° C-190 ° C and try to make a calcined stone. (2) Water, an admixture and additives are added to this calcined gypsum and kneaded in a pin mixer to obtain a raw material for kneaded gypsum. 2. Roll forming step (b) (1) A cover whose both sides are bent is placed on the forming belt conveyor with the front side facing down, kneading gypsum is supplied from a pin mixer, and rolled to a specified thickness with a forming roll.
Place the backing paper on it with the front side facing up to make a continuous plasterboard. 3. Temporary solidification cutting step (c) In order to effectively utilize the property of heat generation and hardening when water is added to the calcined gypsum, the state of a continuous gypsum plate is further conveyed by a molding belt conveyor for about 200 m to achieve solidification and surface smoothness. Take out the product, and then the product size for 2-3 sheets (usually 3
Temporarily cut it into a length with a margin for the number of sheets) and send it as a semi-finished product on the drive roller conveyor. 4. Inversion process (d) The semi-finished product is inverted by an inversion device to protect the surface of the cover, and the cover is sent to the next process so that the cover is on the front side. 5. Drying process (e) Since the semi-finished products still contain a large amount of water even after they are solidified, the semi-finished products are arranged in several stages and several rows in the drying device, and the appropriate time (usually about
Dry for 0 minutes. 6. Finishing process (f) Dried and dried semi-finished product is cut into a predetermined product size with a sizer to obtain a product. 7. Conveying process (g) The product is placed on a conveying device for transportation. Since the gypsum board is manufactured through such a manufacturing process and the manufacturing process cannot be changed, and lines cannot be entered or transferred during the manufacturing of the gypsum board, the Japanese Patent Application No. 6-1.
6758 (Registration 3012259) was considered and the line was transferred to each gypsum board-it was too inefficient for the production speed of the gypsum board and it was very difficult to write the line on the gypsum board. I felt inconvenience.
