The mounting plate 5 is provided so as to be slidable up and down, a pressing device 7 is provided on the mounting plate 5 via an elastic body 6, and a grinding unit 8 for finishing the wall surface is attached to the pressing device 7, and the grinding unit 8 is ground. Position the desired grinding finish a on one wall
Then, a control mechanism 9 for controlling the amount of movement of the traveling vehicle 1 in the front-rear direction and the amount of vertical movement of the mounting plate 5 is disposed on the machine base 2 by a preset program, and the desired wall surface is ground. The present invention relates to a wall surface finishing machine for sticking a wall sheet, wherein the finishing unit a is configured to perform all finish grinding , and a wall sheet is stuck to the wall surface that has been finish- ground by the grinding unit 8. is there.

[0007]

A traveling vehicle 1 having a column 3 standing on the side of the machine base 2 is installed substantially parallel to a wall surface, and the traveling vehicle 1 travels back and forth, and the mounting plate 5 is slid up and down. Filling the approximate center of the grinding surface with a putty on one of the grinding finish points a of the desired wall surface (a concave portion of the wall surface caused by nailing or screwing, or a step formed at the abutting portion of the adjacent plywood, Is pressed to the raised position), the pressing device 7 presses the grinding surface of the grinding unit 8 against the wall surface, and the pressing force of the pressing device 7 and the anti-shrinkage force of the elastic body 6 cause the wall surface to be pressed. After adjusting the pressing force of the grinding surface of the grinding unit 8 with respect to, the grinding unit 8 is driven to finish the wall surface flat, and then the pressing device 7 is operated in reverse to separate the grinding surface of the grinding unit 8 from the wall surface, The traveling vehicle 1 is moved by a predetermined distance according to a preset program. The grinding unit 8 is moved to the next grinding finish point a, and the grinding unit 8 is pressed against the wall surface by the pressing device 7 by a preset program to perform the finish grinding work of the grinding finish point a, and then the grinding unit 8 is automatically ground. The surface is separated from the wall surface to complete the grinding finish at this location.

[0008] This operation is repeated, and a row of grinding finishing points a in the horizontal direction at the same height from the floor plate on the wall surface is programmed by the program.
Carry out finish grinding work.

Next, the mounting plate 5 is slid upwardly by a predetermined amount with respect to the elevating body 4 according to a preset program, and the height of the grinding unit 8 from the floor surface is set to a predetermined height from the grinding finishing point a. After finishing the work of finishing the wall by the same means as described above, the traveling vehicle 1 is retracted by a predetermined distance according to the program, and the next grinding of the same height is performed.
