Looking at the operation and effect of the present invention configured as described above, first, the adsorption plate 70 is balanced in a no-load state without a load. That is, the pneumatic pressure through the main regulator 100 is supplied to the balance cylinder 232 via the balancing regulator 115. When a predetermined pneumatic pressure is supplied to the balance cylinder 232, the cylinder 200 flows up and down along the balance shaft 234, and the touch rod 244 is flowed along the flowed cylinder 200 while the variable valve ( 35). The valve lifts 31 and 32 operate according to the degree of contact, so that the pressure of the balance cylinder 232 is equally adjusted pneumatically according to the load of the suction part and the tilting part so that no load balancing occurs.

Thereafter, the air balancing vacuum adsorption device is positioned by using the rail unit 10 and the rotating unit 12, and the tilting cylinder 50 is three-way switch 140 so that the adsorption plate 70 is horizontal with the glass plate 80.

In addition, when the glass plate 80 is adsorbed as described above, as the load is applied to the lifting part, the cylinder 200 flows, and the valve lift 32 is moved by the touch bar 244 that flows. Therefore, the pneumatic pressure is additionally supplied into the lift cylinder 212 to automatically balance the load state.

Thereafter, when the glass plate 80 is moved upward by using the movement knob 60, the push button switch 120 (upward button) is operated to supply air pressure into the lift cylinder 212. At this time, as the lift piston 210 rises, the pressure of the exhaust cylinder 222 is discharged through the exhaust port 226 to raise the glass plate 80 to a desired position of the operator. Then, when the glass plate 80 is moved through the rail unit 10 and the rotating unit 12 and the push button switch 121 (down button) is pressed, the pressure in the lift cylinder 212 is lowered, and due to the weight of the load The glass plate 80 is lowered. At this time, the outside air is introduced into the exhaust cylinder 222 through the exhaust port 226.

When the glass plate 80 is moved to a desired position, the air operator valve 130 is operated to remove the vacuum of the vacuum adsorption pad 75 to remove the glass plate 80 to complete the movement of the glass plate 80. .
