      Looking at the patent literature in contrast to the present invention, there is a 'robot mechanism (Patent registration No. 10-0350849) for the painting of the wall advertisement', the difference from the present invention is as follows.

      In the above invention, the vacuum pad 38 has been proposed for the purpose of fixing the frame 20 to a building, which is difficult to apply to cement walls in addition to glass and tiles to which the wall is attached.

      Mounting the paint or ink on the frame 20 in the spray head 40 and the injector 46 is also suitable for places with a small paint area, for example, where a small amount of paint is sprayed, and apartments that require a large amount of paint. It is not suitable for the walls of construction sites for building skyscrapers.

The present invention relates to a building wall automatic coating equipment, and to a building wall automatic painting equipment that allows the worker to paint with a spray gun that can be automatically transported without a ladder hanging work at high altitude.
In order to paint the walls, conventionally, the rope was pulled down from the roof layer, and the worker grabbed the rope with one hand, spray gun with the other hand and sprayed the paint on the wall. It is a method and it is not easy to prevent the spread of paint dust. There are other ways to push with a roller brush, but there is a drawback of poor work efficiency.

In order to improve this inefficient wall painting process and automate as much as possible, the present invention first covers the width of the wall and creates a ladder that can be lifted up by a person, then roofs two or more masts to support the rope. It is installed on the floor, tied the rope to the mast loop, down the wall, and then attached to the rope with the so-called winder attached to the rope to wind up the rope so that the ladder can be raised or lowered by an electric winder:

The paint spray gun is intended to traverse the bottom of the ladder, after mounting the rails and trolleys and rack gears on the bottom of the ladder, several trolley brackets are fixed to one saddle and several spray guns are mounted on the saddle top, One end of the paint and air transport hose following the gun is hooked up to another trolley to form a trolley row, and then a geared gear reducer is installed on the saddle to allow traversing by the motor.

In addition, several kinds of color spray guns should be installed in accordance with the pattern of the wall to paint the patterned wall. Electrical circuits should be constructed with a working PLC, etc., to enable the lamp to be operated from the control panel.

The equipment of the present invention is a facility in which paint containers, electric paint pumps, air compressors, paint containers, various spray guns and ladders, roof masts, ropes, etc., are wide and distributed at the same time. It should be easy and light to disassemble or withdraw, and at the same time ensure that the split components are not damaged when loading or unloading the vehicle.
