BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating robot apparatus for switching a discharge amount of a coating material. The present invention relates to a coating robot apparatus for switching a paint discharge amount, which is designed so that a single coating gun and a single pump can perform coating with high efficiency without being replaced midway, and that the film thickness can be reliably ensured.

[0002]

2. Description of the Related Art Conventionally, when airless painting a work,
In general, painting was performed using a painting robot having one painting gun, one airless pump, and one driving air system. Therefore, in the case of a workpiece having a complicated shape or a plurality of workpieces flowing on the same line, depending on the location, the coating may be performed with a single coating gun without guaranteeing the film thickness, or the workpiece may be painted at a certain location. The painting gun is changed for each painting type.

[0003]

However, in this conventional painting robot apparatus, when painting is performed with one painting gun, the moving speed of the painting gun is limited. It is difficult to guarantee, and in the end, the coating quality must be reduced.On the other hand, when changing the coating gun, the processing efficiency is greatly reduced, and the coating cost is increased by that much. There was a point.

[0004] A method of holding a plurality of coating guns on a coating robot to perform coating is also conceivable. In this case, when a work having the same shape is coated with a different film thickness, the coating gun of the coating robot is required. Since the holding positions are different, even if a workpiece having the same shape is painted, a different painting path must be taught to the painting robot for each painting gun, and there is a problem that a great deal of time is required for teaching.

The present invention solves the above-mentioned conventional problems, and uses one painting gun and one pump when painting by changing the discharge amount variously depending on the painting part and painting type of the work. It is another object of the present invention to provide a paint discharge amount switching coating robot apparatus capable of performing coating with high efficiency and a film thickness that is reliably guaranteed.

[0006]

SUMMARY OF THE INVENTION The present invention provides a paint gun,
A robot that holds the paint gun and urges it toward the painting position for the workpiece, an airless pump that supplies paint to the paint gun, and a plurality of air systems that selectively set the air pressure that drives the airless pump An air switching unit that switches by switching, and stores the painting data and air system selection data for the workpiece, sends a signal to the robot based on them, controls the painting attitude of the coating gun on the workpiece, and selects the switching unit. This is a coating robot apparatus for switching a paint discharge amount, which includes a control unit that sends a signal and controls air switching of the switching unit.

In the present invention, conventionally known coating guns and airless pumps are appropriately used. In the present invention, the robot is a conventionally known articulated robot or the like, and a painting gun is held on the wrist of the arm, and various painting postures on the work can be taken by the movement of the joint and the arm. Is preferably used.

In the present invention, the control unit can store coating data such as a coating portion of a work, a coating type (coating film thickness, the number of coatings, etc.), a coating order, and air system selection data, and based on these data. In addition, it has a function of sending a signal to the robot to control the painting posture of the painting gun with respect to the work, and sending a selection signal to the switching unit to control air switching of the switching unit.

[0009]

The coating robot apparatus for switching the amount of discharged paint according to the present invention includes a coating gun, a robot that holds the coating gun and urges the coating posture toward the object to be coated, an airless pump that supplies the coating gun with the coating, and an airless pump. An air switching unit that selectively selects and switches a plurality of air systems, each of which sets the air pressure for driving the air, and stores coating data and air system selection data for the object to be coated, and sends a signal to the robot based on them. A control unit that controls the painting posture of the feed coating gun with respect to the workpiece and sends a selection signal to the switching unit to control air switching of the switching unit enables one coating gun and one pump to be installed. By simply using it, the discharge rate can be changed in various ways depending on the coating site and coating type of the workpiece to achieve a highly efficient coating that ensures the film thickness. In addition, as in the case of painting while holding multiple painting guns in the painting robot, the painting robot must be taught different painting routes despite painting the same shape work. There is no complication of not becoming.
