2. Description of the Related Art In this type of airless automatic coating apparatus, a nozzle tip is selected by previously setting the amount of paint sprayed per unit time and the pressure applied to the paint, and the paint applied to the object to be coated accordingly. The film thickness of is also set. However, when coating is performed, the film thickness of the coating material applied to the object to be coated gradually becomes thicker than the set film thickness. This is because the nozzle hole of the nozzle tip is abraded by the pigment or the like contained in the paint, the diameter is expanded, and the amount of paint ejected from the nozzle per unit time is increased.

Here, FIG. 4 shows the experimental results of examining the relationship between the number of coatings of the article to be coated and the film thickness of the coating material applied to the article. According to FIG. 4, after the coating of a predetermined number n of coating objects is completed, the amount of coating material ejected from the nozzle per unit time increases rapidly, and the film thickness of the coating material applied to the coating object increases. Becomes thicker than the set film thickness of 20 μ. However, at this point, if the film thickness of the paint applied to the object to be coated is reduced by decreasing the pressure applied to the paint and reducing the amount of gas ejected from the nozzle, the atomization of the paint becomes worse. It adversely affects the coating quality. Therefore, in actuality, the nozzle tip is replaced at the time when the coating of n objects has been completed so that the amount of paint ejected per unit time does not exceed the allowable amount from the set amount.

However, if the nozzle tips are replaced at the time when the coating of n objects has been completed, the nozzle tips must be replaced frequently, resulting in a high cost. In addition, it is troublesome to manage the nozzle tip replacement time, and if the coating line is temporarily stopped after each nozzle tip replacement, productivity will decline. Therefore, the present invention, even if the amount of paint spray per unit time increased due to wear of the nozzle tip, without replacing the nozzle tip,
A technical problem is to be able to maintain a constant film thickness of a paint applied to an object to be coated.

According to the present invention, when the coating is started, the cumulative spray amount of the paint is calculated by the spray amount calculating means, and when the cumulative spray amount exceeds the set amount, the controller determines the cumulative spray amount of the paint. A corresponding moving speed of the coating machine is set, and a control signal for increasing the moving speed of the coating machine is output to the speed adjusting means. Since the amount of paint ejected from the nozzle per unit time gradually increases due to the abrasion of the nozzle tip, the film thickness of the paint applied to the object to be coated tends to increase. However, the degree of wear of the nozzle tip is almost proportional to the total amount of paint sprayed from the nozzle, that is, the cumulative spray amount.Therefore, the rate of increase in the moving speed of the coating machine corresponding to the increase in the cumulative spray amount of paint must be obtained by experiments in advance. Then, if the moving speed of the coating machine is increased based on this, the moving speed of the coating machine will be increased according to the degree of wear of the nozzle tip, that is, the increase in the amount of paint sprayed from the nozzle per unit time. The amount of paint applied per unit area of the coating is reduced and offsets each other, so it is not necessary to change the nozzle tip frequently, and the thickness of the coating applied to the object is kept constant. be able to.

Since the amount of the coating material applied per unit area of the object to be coated W is reduced and offsets each other, the film thickness of the coating material applied to the object to be coated 2 is maintained constant without replacing the nozzle tip. be able to. Further, it is not necessary to frequently replace the nozzle tip, and the reduction in productivity when the coating line is temporarily stopped is alleviated.

It should be noted that a timer is provided in the control device 7 as a jetting amount calculating means, the timer measures the time during which the opening / closing valve 4 is opened, and the opening time is calculated based on a preset opening time-speed conversion table. You may set the moving speed of the coating machine 2 according to. This is because the opening time of the open / close valve 4 is proportional to the cumulative spray amount of the paint, so that the cumulative spray amount of the paint can be calculated by measuring the open time, that is, the degree of wear of the nozzle tip, the result, the unit sprayed from the nozzle.

Further, a counter 13 for measuring the number of input detection signals, that is, the number of objects W to be coated is provided in the control device 7, and the counter 13 is a specific example of the ejection amount calculating means in this example. When high-pressure paint is sprayed from the nozzle in the coater 2 to start coating and the number of objects W to be detected detected by the detection sensor 11 reaches a predetermined number or more, the controller 7 sets the preset number. -A moving speed of the coating machine 2 is set according to the number based on the speed conversion table, and a control signal based on the set speed is output to the inverter 10.

As described above, according to the present invention, the coating machine is moved according to the cumulative jet amount from the time when the cumulative jet amount of the paint calculated by the jet amount calculating means exceeds the set amount. When the speed is set and increased, the moving speed of the coating machine is increased according to the degree of wear of the nozzle tip, that is, the increase in the amount of paint sprayed from the nozzle per unit time. Since the amount of paint that adheres decreases and offsets each other, it is possible to maintain a constant film thickness of the paint that is applied to the object without replacing the nozzle tip, and frequent nozzle tip replacement is required. It has a very excellent effect that the decrease in productivity due to the temporary suspension of the coating line is alleviated because there is no need to carry out it.
