Description

Controlling spindle device for products coat with paint system

The present invention relates to a spindle control apparatus of a product coating system, and a plurality of products can be mounted on a spindle to quickly process a large amount of products, and the spindle's operating direction and operating state are controlled by the spindle reverse rotation body. The present invention relates to a spindle control apparatus for a product coating system which attempts to minimize product defects by sequentially coating the product.

In general, the spraying device for painting is to form an air inlet for supplying compressed air and a paint supply for supplying paint, such as paint, in the body of the spray device, respectively, integrating these air inlets and one outlet of the paint supply. A nozzle for spraying is installed at the tip of the site and paint is sprayed through the nozzle. The spray device configured as described above is coated on a product (hereinafter referred to as a product). In order to work, the air inlet and the paint supply are respectively connected to the air pipe of the compressed air controller and the paint supply supply pipe, and the compressed air supplied from the compressed air controller to convey the liquid or solid powder paint to the nozzle The paint is injected through the nozzle while the paint is pushed along the spray passage, Sadoen coating material is deposited on the product is to occur the coating (塗裝).

As a spray device, an aerosol liquid sprayer using Freon gas is frequently used as a sprayer for continuously spraying liquid.

In this aerosol-type liquid sprayer, the aerosol valve is opened by pressing the head of the upper end of the valve pipe which is pressurized from the aerosol-type valve at the upper end of the container and pressurized by the freon gas in the container body. It is ejected through the tube.

This aerosol-type liquid sprayer is extremely convenient because the valve is opened and the pressurized liquid is ejected simply by pressing the valve tube of the aerosol-type valve. However, since the freon gas used for pressurization is released into the atmosphere, it rises to an extremely high level and destroys the ozone layer. There is a demand for a passive liquid sprayer capable of continuously ejecting without using freon gas.

Looking at a conventional example of the application of such a coating device, Figure 1 is a table (8) to be maintained at a certain distance from the floor of the work room in Figure 2, and is mounted on the top of the table (8) The chain and the frame 15 are connected so that the product 12 can be conveyed, and the conveyor rotating body 14 which transmits power is connected.

The table 8 is connected to a spindle 11 arranged at a constant distance so that a plurality of products 12 can be combined.

The table (8) is a manufacturing chamber (1), upper and lower paint chamber (4) (2) and lower coat drying chamber (3), solvent drying chamber (5) and cooling chamber so that the product 12 can be smoothly painting process (6) is connected, and the ultraviolet curing chamber 7 is arrange | positioned at last.

In addition, the table 8 is connected with a spindle 11 into which the product can be inserted into the table 8 for painting on the product 12, which can be fitted with one product 12. And a spray fixture 13 installed in a plurality of directions at the top of the table 8 so that the product 12 may spray paint on the surface of the product 12 when the product 12 rotates while being transported in a predetermined direction. Has a configuration.

The conventional coating apparatus configured as described above first puts the spindles 11 on the table 8 of the main conveyor 10 by one or five persons to paint the product by the worker. At this time, the product 12 is inserted into the spindle 11, the main conveyor table (8) is moved to the position of the reposition chamber (1), and the dust core made of iron core so that painting is primarily desired in the reposition chamber (1). To remove static electricity and dust.

The static and dust-free product flows through the main conveyor to the location of the undercoating chamber (2), allowing the undercoating to be made through the fixing gun (13), and when the undercoating is finished, in the solvent drying chamber (5). Allow the paint to dry.

After painting the finished product, the top coat is done again and then dried in the solvent drying chamber (5). At this time, the cooling chamber (6) to cool off the heat generated to dry the paint on the product in the solvent drying chamber (6). ), And the finished product passes through the UV curing chamber (7) to coat the part coated with ultraviolet rays so that the paint coated on the product 12 does not peel off due to external friction or impact. Will be processed.

In addition, the finished product 12 is to remove the coating from the spindle 11 one by one to insert the product to be coated 12 to be completed by the above-described process.

However, since the spindle conveyor of the conventional coating apparatus always moves at a constant speed, it is difficult to carry out step by step as the fixed gun 13 quickly executes a painting operation within a predetermined time in a set operation direction.

In addition, the conventional spindle tool (tool) is a single product 12 is coupled to one spindle 11 so that the painting work is carried out by the spindle tool is always required to proceed in the same direction at a constant speed, the time required for painting work Has to be set to the speed of the spindle tool, so there are many problems with painting.

Another conventional problem is that only one product 12 is coupled to each spindle 11, so that it is difficult to perform a number of products 12 at the same time, and the mass production of the product is difficult. Since the fixed gun 13 is fixed in position, only a certain position of the product is intensively painted. Therefore, the entire surface of the product cannot be evenly painted, and only one position is intensively painted. As a result, the surface of the painted product is irregularly formed. It has a problem of degrading product quality.

The present invention is intended to solve such problems in the related art, the object of which is to mount a large number of products on the spindle to quickly process a large number of products, the spindle operating direction and operating state by the spindle reverse rotation body This is to minimize the defects of the product by controlling so that the painting can proceed sequentially.
