Abstract

PURPOSE:To save a paint and to reduce the coating time by fixing a coating gun to a rotary device revolving with the radius of rotation half the necessary width to be coated and directing a gun to the horizontally moving material to be coated. CONSTITUTION:With respect to the device for coating the front side of the cabinet of a television set, etc., a television cabinet 1 having the window of a cathode-ray tube part and the window of the control panel part is set so that the cabinet is directed upward and continuously transferred in the horizontal direction. Then the centers of the rotary shafts of the coating devices are set at the parts X1 and X2 and the rotary side arms having the radii of rotation b1 and b2 sufficient to coat the width B are fixed to the shafts. Since only the part to be coated is coated, the loss of paint is eliminated and the coating time is remarkably reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION - Industrial Application Field The present invention relates primarily to a coating device for coating the front side of a television cabinet.

・Prior art and its problems A window for the cathode ray tube section and a window for the control panel are open on the front side of the TV cabinet, so there is no need to paint these parts.

However, in the case of a conventional rotary complete continuous coating apparatus, as shown in FIG. The rotating horizontal arm 04 is attached, and the gun 06 is connected to the rotating horizontal arm 0 via the rotating vertical arm 05.
4, and while rotating the gun 06 around the rotary rotation axis O1, the entire front face of the cabinet 03 is uniformly painted.

FIG. 6 is a diagram explaining the principle of the above-mentioned conventional example, in which the center axis of rotation of the rotary rotating shaft is χ, the radius of rotation of the rotating horizontal arm 04 is a, and the front surface of the TV cabinet 03 is at the radius of rotation a. It is within the width A to be painted.

Therefore, in the above-described coating method, the window 07 of the cathode ray tube section and the window 08 of the control panel section of the cabinet 03 are also uniformly coated, as shown by diagonal lines in FIG.

As a result, there was a problem that the paint sprayed on unnecessary parts was wasted and the painting time became longer.

eObject of the present invention The purpose of the present invention is to save paint and shorten the painting time by painting only the necessary parts.

・Structure of the present invention As a means to achieve the above object, the present invention disposes a rotary device that rotates at a rotation radius set to approximately 1/2 of the width to be painted toward a horizontally moving object, and We propose a painting device consisting of a rotary device with a painting gun attached.

In this way, by placing the paint gun only within the range of movement of the areas that need painting and preventing paint from being sprayed on unnecessary areas, you can save paint and reduce the area to be painted. Therefore, the painting time is also shortened accordingly.

·Example An embodiment of the invention is shown in Figure 1.2.

In this embodiment, a TV cabinet 1 has a window 2 for the cathode ray tube section and a window 3 for the control panel section on the front side. ,
This is a case where painting of parts other than 3 is required.

In the case of this coating device for the TV cabinet 1, a horizontal conveyor (not shown) is arranged, and the cabinet 1 is set on this so as to face upward, and the cabinet 1 is continuously transferred horizontally. .

The center of the rotary rotation axis of the coating device is set at the portions χ1 and χ4, and is inserted into this rotary rotation axis.

A rotating transverse arm with a rotation radius for painting the width B is attached.

FIG. 2 shows the front of the cabinet 1 after it has been painted using the apparatus described above. In FIG. 2, the shaded area is the painted surface, and the window 2 of the cathode ray tube section and the window 3 of the control panel section are not coated.

Incidentally, when painting is performed as described above, the parts not shaded in FIG. 2 are unpainted parts. Therefore, in order to paint this area, rotate the cabinet 90' with respect to the direction of travel of the conveyor, and arrange the coating equipment for the unshaded area along this direction of travel, similar to that in the previous embodiment. It will be painted.

FIG. 3 shows the complete state of painting, and the parts of the cabinet 1 that require painting other than the window 2 of the cathode ray tube section and the window 3 of the control panel section have been completely finished in two successive steps.

FIG. 4 shows a second embodiment, in which the object to be painted is circular, there is a circular window 4 in the center, and the area that requires painting is the width of concentric circles.

In this example, the object to be coated is rotary table L.
The center of the rotary rotating shaft is χ31, the radius of rotation is bJ, and the width is painted in the same manner as in the first embodiment.

In this second embodiment, the same coating can be performed even if the table side is fixed and the coating device side is rotated (moved) along the width.

・Effects of the present invention As described above, the present invention is configured such that a gun is arranged to paint only the necessary parts of the object to be painted, and unnecessary parts are not painted at all, so there is almost no loss of paint. However, the effect of significantly shortening the painting work time can be obtained.
