Description

This device is designed to facilitate resetting to the same state as before the interruption when the spray gun installed in the painting machine and used for automatic painting is interrupted for inspection and then installed again in the painting machine. It relates to a jig.

Automatic painting equipment is often used to increase the productivity of industrial painting. Automatic painting enables painting with a stable quality by repeatedly and accurately performing a coating machine equipped with a spray gun. Therefore, it is important to install a spray gun based on the result of repeatedly testing the most appropriate state first and to maintain that state correctly.

Although spray guns installed in painting robots and automatic painting equipment are used continuously for a long time, it is inevitable that the painting conditions fluctuate due to various factors, and it is confirmed that they are operating normally at regular intervals. Is needed. Continuing painting without giving notice of fluctuations and avoiding a large amount of painting failure must be avoided, and the work will be temporarily stopped based on past experience and experience, and necessary confirmation work will be performed.

The most variable factors in painting work are likely to fluctuate, and the discharge rate is raised as a condition that affects the quality of painting. If the facility allows it, the flow rate is automatically checked and corrected, etc. Although it is possible to adopt this discharge amount management system, in many cases, it is currently limited to human work.

In this case, the painting operation is interrupted, the spray gun is removed from the mounting shaft, and the discharge amount from the spray gun is actually measured, or the spray gun discharge direction is different from the direction of the object to be coated while it is attached to the mounting shaft. It is done by a method of measuring and confirming the actual discharge amount by placing a paint receiver on the bottom and facing downward. And if necessary, after adjusting, it will be set to the state before work interruption again and the painting work will be continued.

As mentioned above, it is necessary to set the spray gun accurately, and if the installation angle is different, the finish of the paint will be different and the quality will vary, so it can be installed in the same state as before the work interruption, and the work It is necessary to be able to do this easily.

The present invention improves the reproducibility of the mounting angle when fixed to the automatic gun mounting shaft of an automatic coating machine, and stabilizes the coating quality in automatic coating. The challenge is to improve the efficiency of work by enabling one-touch resetting to the state before the interruption.

A jig equipped with fastening means that can be freely selected and fixed on the mounting position of the automatic gun is provided on the mounting axis of the automatic gun that can be freely selected and mounted. A locking piece that restricts the position and stops the rotation by contacting at a predetermined position is provided. When it is fixed at a regular automatic spray gun mounting position, positioning can be performed by fixing the jig locking piece at a position in contact with a part of the automatic gun. This locking piece is separable from the jig body and can be exchanged for a shape that matches the automatic gun.

The automatic spray gun can be fixed at any time by fixing in advance a jig provided with tightening means that can be freely selected and fixed with the locking piece in contact with the fixed position of the automatic spray gun. It is possible to easily set the same position. When it is removed or the position is changed, it can be easily returned by one-touch operation without re-measurement or reconfirmation of the spray direction when returning to the original position again. Therefore, work interruptions can be minimized, adjustment time can be shortened, and operator adjustment errors can be prevented.

There are various structures, sizes, etc. of the automatic spray gun, and the position and shape of the abutting locking pieces cannot be fixed or shared. Since the present invention is detachable so that the locking piece can be exchanged according to the automatic spray gun used, it can be adapted to many automatic spray guns.

FIG. 1 shows a partial cross section of the jig 1 of the present invention. The main body 2 has an annular shape with a partially cut portion 21, and the mounting shaft 3 is inserted into the center portion. The cutting part 21 has a structure in which the bolt 4 is inserted from one side and screwed into the other, and the inner diameter of the central part can be adjusted. Accordingly, after the mounting shaft 3 is inserted, the screws are fixed to the mounting shaft 3 by tightening screws.

This fixing method itself is a commonly used technique, and various other tightening means such as applying a force directly to the shaft and fixing it with a frictional force may be used.

A locking piece 5 is provided on a part of the main body so as to protrude from the outer peripheral portion. In the illustrated example, a metal fitting bent into an L shape is attached by a screw 6 so as to be exchangeable. If the use is limited to a specific automatic spray gun, the original purpose can be achieved even if it is formed integrally with the main body 1.

The spray gun fixed to the mounting shaft 3 of the automatic coating machine is generally mounted in a state where it can rotate around the mounting shaft. 2 and 3, the automatic spray gun 7 is fixed to the mounting piece 18 of the mounting stay 8 fitted to the mounting shaft 3 with bolts or the like. Therefore, the automatic spray gun 7 is rotated around the mounting shaft 3 by the mounting stay 8 and can be fixed at an arbitrary position by tightening the fixing screw 9 or the like.

The locking piece 5 and the automatic spray gun 7 or a part of the mounting stay 8 integrated with the locking piece 5 are in contact with each other, and are positioned so that the rotation of the other is restricted by fixing one. Therefore, first, the automatic spray gun 7 is fixed at an appropriate position after confirming the coating on the object to be coated. The jig 1 is rotated in accordance with the fixed position so that the locking piece 5 is attached to the automatic spray gun 7 or the mounting stay 8. The jig 1 is fixed when it comes into contact with a part. When the automatic spray gun 7 is removed for inspection / confirmation in the middle of the painting work, or when the fixed position is changed to the position indicated by the dotted line and is fixed again at the same position, the fixture 1 already fixed The automatic spray gun 7 may be fixed again at a position where the automatic spray gun 7 or a part of the mounting stay 8 comes into contact with the stop piece 5.

The example of FIG. 4 is an automatic spray gun 17 having another form. This automatic spray gun 17 includes a fixing means for an attachment shaft in the gun body and does not use an attachment stay. Accordingly, the locking piece 5 of the jig directly contacts a part of the automatic spray gun to determine the fixing position.

In these cases, the contact position varies depending on the shape of the automatic spray gun, and it is necessary to change the shape and position of the locking piece. In such a case, it can be carried out in an appropriate state by enabling replacement according to an automatic spray gun using a locking piece.

It is the figure which showed the structure of the jig | tool of this invention, and showed the part of the one part fixing means in the cross section. It is an attachment state figure which shows an automatic spray gun and a related position. The side view which looked at FIG. 2 from the right side. It is a figure which shows the attachment state of the automatic spray gun which has another form.
