This seating means, as shown in Figure 3 is fixed to the rod-like body 25, and at the same time having a horizontal bar 26, the magnets 26a are arranged at regular intervals on both upper surfaces, the horizontal bar 26 The jig 27 is seated on the upper side of the jig 27 so as to be detachable by a magnetic force, and a plurality of fixing pins 27a on which the workpieces W are mounted on the jig 27 are arranged side by side at a predetermined interval. It is.

Here, the jig (27) can be easily replaced by manufacturing in various forms according to the size or shape of the workpiece (W), the fixing pin (27a) arranged on the jig 27 is also the workpiece (W). It can be produced in various ways depending on the size and shape of the).

In addition, the upper plate (23B) mounted on the upper side of the main body 21 is to be able to move in the left and right direction in the state coupled to the expansion means provided in the frame (11).

That is, as shown in FIGS. 5A and 5B, the expansion means has an upper cover 28 mounted on the frame 11 and having a long hole 28a formed in the longitudinal direction near the center thereof. The bellows 29 is built in the guide 28b formed at the lower end of the body 28.

And, as shown in FIG. 6, the injection unit 30 for injecting paint on the object to be coated (W), the upper plate (32A) and the support plate 31 mounted on the frame 11 and A plurality of stationary rods 33 held through the lower plate 32B are provided, and within the stationary rods 33, spray guns 34 freely adjustable by height and position adjusting means are disposed.

The height adjusting means is installed between the fixing rods 33, each handle 35 is composed of a screw rod (36) rotated in the forward and reverse directions, and the control rod (37) mounted on the screw rod (36) , The position adjusting means is composed of a rotating shaft (39) holding the spray gun (34) via a bracket (38) mounted at the end of the adjusting rod (37).

In addition, in the present invention, as shown in FIG. 1, the spray unit 30 is arranged in four, but the spray unit 30 corresponds to the size or shape of the object to be coated (W). It can be installed in less than four or more depending on whether the shape is complicated or the size of the large and small to-be l, the top and bottom open or closed.

On the other hand, one side of the frame 11 is provided with a stopper means is configured to set the initial position of the holder unit 20.

7A and 7B, the stopper means has a support plate 40 which is installed perpendicular to the frame 11, and the first bracket 41a mounted on the support plate 40 has a cylinder. An arm 43 provided so as to be adjustable in position as 42 is mounted, and the arm 43 is fitted into the long hole 44 formed in the second bracket 41b and at the tip of the arm 43. It consists of a positioning piece 45 mounted.

In addition, as shown in FIG. 8, one side end of the frame 11 is provided with a distributor 50 to supply paint, and the distributor 50 is installed on a support rod 51a mounted to the frame 11. In addition, it is comprised so that paint may be supplied to each spray gun 34 through the hose 53 which has each valve 52.

That is, the dispenser 50 is supplied with a liquid only paint according to the use or form of the object to be coated (W) by driving a pump (not shown), or a paint that can exhibit unusual coating effects by including particles in the paint. Is selectively supplied, and the flange 54 mounted on the body 50a of the distributor 50 is connected to the drive member 55 on the support rod 51b.

The drive member 55 can swing the body 50a of the distributor 50 intermittently by repeating the rotation in the forward and reverse directions so that the paint does not settle in the distributor 50 by this operation. do.

According to the present invention configured as described above, first, the workpiece (W) is inserted and fixed on the fixing pin (27a) arranged side by side on the jig (27) constituting the holder unit 20, at this time The jig 27 or the fixing pin 27a can be selected and used according to the size or shape of the object to be coated (W).

In this manner, the horizontal bar 26 is placed on the horizontal bar 26 provided on the upper end of the rod-shaped body 25 of the holder unit 20 in the state in which the workpiece W is mounted on the jig 27. The jig 27 can be attracted and fixed by the magnet 26a provided in the holder.

Thereafter, the cylinder 42, which is provided on one side of the frame 11 and constitutes a stopper means, is operated to set the initial position of the holder unit 20 by the positioning piece 45 mounted at the tip of the arm 43. At the same time as the zoom is retracted to the original position, it is possible to perform the painting work on the workpiece (W) according to a predetermined program.

That is, as the driving motor 12 moves by the switch operation (not shown) to rotate the screw bar 14, the main body 21 moves in the right direction in FIG. 1 and the body 50a of the distributor 50. ) And the paint stored in the) is supplied to the spray gun 34 through each hose 53 and sprayed toward one side of the workpiece W held by the jig 27.

At this time, the spray guns 34, as well as the height of the adjustment rod 37 by the rotation of the screw rod 36 by the handle 35 in accordance with the size or shape of the workpiece (W), the adjustment rod ( 37) The spray angle of the spray gun 34 attached to the bracket 38 at the tip is already set.

As described above, when the holder unit 20 moves and is located at the right end, a sensor (not shown) senses the same and operates the rotary cylinder 24 mounted in the main body 21 so that the rod-shaped body 25 rotates. By reversing the position of the water to be coated (W) mounted on the jig 27 and at the same time to move the holder unit 20 to the left again.

Therefore, the coating by the spray gun 34 is sprayed toward the opposite side of the object to be coated (W) is to be painted on the entire surface of the object to be coated (W), the holder unit 20 is Reach the initial position and stop.

Here, the feed rate of the holder unit 20 by the drive motor 12 or the rotational speed of the rod-shaped body 25 performing the turn operation by the rotary cylinder 24 is appropriately adjusted according to the object to be coated (W). It is supposed to be.

On the other hand, since the holder unit 20 is moved to the left and right directions through the bellows 29 in the upper cover 28 constituting the expansion means, paint or other sprayed from the spray gun 34 This prevents foreign matter from flowing into the device.

In addition, the paint is provided to the dispenser 50 by a pump driving (not shown), and the paint can be supplied to the spray gun 34 through each hose 53 and sprayed.

These spray guns 34 can be arbitrarily cut off by the valves 52 mounted on the respective hoses 53, and can be installed in an appropriate number corresponding to the size or shape of the object to be coated (W). Of course.

In addition, since the distributor 50 is intermittently swinged by the driving member 55, it is possible to prevent the coating material from settling in the distributor 50 over time.

Although the above-described embodiments have been described with respect to the most preferred examples of the present invention, it is not limited to the above embodiments, and it will be apparent to those skilled in the art that various modifications can be made without departing from the technical spirit of the present invention.

As described above, according to the automatic coating machine according to the present invention, it is configured to perform a turn operation at the same time while moving the workpiece to be maintained at a predetermined interval in the jig on the holder unit of the frame to the left and right directions. Since a plurality of spray guns disposed on one side of the frame is configured to uniformly spray the paint onto the entire surface of the object to be coated, the coating performance is excellent and the work can be efficiently performed with a relatively simple configuration.

In addition, the present invention allows the jig on which the to-be-painted object is mounted to be detachable from the holder unit, so that the jig can be easily replaced according to the size or shape of the to-be-painted article, thereby greatly widening the use range.
