Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet adhesion pressurizing device used when adhering a fiber cloth (sheet) to a folded plate.

Generally, one side of folded plates such as metal plates and asbestos plates used as roofing and wall materials is covered with fiber cloth (mainly inorganic fiber non-woven fabric, hereinafter referred to as non-woven fabric made of inorganic fibers) that has functions such as non-combustibility, heat insulation, sound absorption and prevention of dew condensation. (referred to as a sheet), if the sheet is within 5n thickness, either a) the sheet is pasted manually using adhesive on a formed folded plate, or (a)
A sheet is attached using a machine to a flat metal plate before it is formed into a folded plate, and then it is formed into a folded plate.

In the case of (a) above, the properties of the sheet are not impaired, but it is necessary to proceed from one end of the folded plate to each uneven plane by pasting the sheet, which requires a lot of manpower and is inefficient. The product is heterogeneous.

In the above case, the thickness of the sheet is reduced by the pressure of the rolls of the forming machine when processing and forming the sheet into a folded plate, and its properties are lost.

In addition, when pasting together sheets of 10 or more dimensions, the flat metal plates pasted with these sheets using the method described above will be difficult to form into folded plates, and the dimensions of the molded product will not be determined and cannot be formed. So, in this case, I mostly use method a).

Conventionally, as shown in Japanese Unexamined Patent Publication No. 51-92355, a folded plate is placed on a fixed stand, and a forming and crimping device is movably supported on a pair of rails located on both sides of the folded plate. By making this forming and crimping device run automatically along the upper surface of the folded plate, while unwinding the flat sheet that has been wound up on the forming and crimping device, the forming and crimping device allows the unevenness of the folded plate to be formed on the sheet. There is a method in which a concave-convex strip that matches the strip is cut out, and the sheet is affixed while the concave-convex strip matches the top surface of a folded plate coated with adhesive while being crimped with a pressure roll of a forming and crimping device. .

However, the device disclosed in this publication uses a large number of rolls that are directly or indirectly necessary for shaping the flat sheet in order to gradually shape the uneven stripes on the flat sheet while moving the forming and crimping device along the folded plate. Because of this, it is almost impossible to adjust the vertical movement and pitch of each roll.

For this reason, since there are many different shapes of folded plates, it is necessary to create a separate device for each type or replace the parts of the device, and although it is easy to glue the entire length of the folded plate, If a sheet is attached to the entire surface of a folded plate when used on a roof, the sheet will absorb water and leak, so it is necessary to leave both ends of the folded plate open and attach it each time. Since it is necessary to open a predetermined space for pasting, manual labor is required at the beginning and end of pasting, and the device must be returned to the starting point of the folded plate after each pasting, which is inefficient. In particular, when pasting sheets onto short folded plates, the efficiency is lower than when pasting them manually. The present invention was made in view of the above points, and it is possible to shape the concave and convex portions of the sheet and apply pressure for pasting with high efficiency when pasting the sheet to a folded plate. The purpose of the present invention is to provide a pressurizing device for sheet adhesion, in which a folded plate mounting table is provided at the lower part of the device body, and a lower folded plate is mounted on the upper part of the device body by an elevating drive mechanism.
