Description

[Detailed Description of the Invention] The present invention relates to a coating device, particularly a coating device suitable for small-volume production and coating articles of various shapes and strip sizes.

Traditionally, items produced in small quantities, such as hobby ornaments such as gavel dolls, or a wide variety of products such as candlesticks, urns, and ashtrays,
When painting small daily necessities produced in small quantities, the article is coated with a resin, etc. to improve the photoselectivity of its appearance and the vapor deposition properties of the post-process, and after Ap vapor deposition, the painting is done manually. And I was finishing it.

For mass-produced items, stealing an automatic painting line will lead to lower costs, but for low-volume production of items with short life cycles and different shapes, automating the painting process Purchasing various machines and stealing production lines actually causes higher costs.

For this reason, manual painting is generally used.

However, manual painting is not only low in productivity, but also has various drawbacks, such as the quality of the product varying depending on the skill level.

The reason why the painting process for such small-volume products cannot be automated is because the automated line for the painting process for a specific item cannot be used for painting other items.

In view of the above facts, the inventor of the present invention sought to provide a coating device that can be commonly used for various articles.

Therefore, it is an object of the present invention to provide a coating apparatus that is effective for coating various substrates of various shapes and sizes.

That is, the present invention includes a support machine that supports an object to be coated and has a rotatable metal rod and has a magnet on its side wall; and a support machine that detachably fixes the support machine by attracting the magnet. a conveying chain having a plate; a rotating magnet provided so as to come into contact with a metal rod of the supporting machine and rotate the metal rod as the conveying chain moves; a vicinity of the rotating magnet; and a coating spray for coating the object to be coated supported by the metal rod.

To explain the present invention in more detail, FIG. 1 is a side view of a supporting machine according to an embodiment of the present invention.

As is clear from FIG. 1, the support machine 1 has a metal rod 10 for supporting the object to be coated. Wall surface 1
3 and is erected at the desired height.

Bearings 14 are inserted into the insertion portion of the intermediate stand 12 and the metal rod 10 portion of the bottom stand 11, so that the metal rod 1o can rotate smoothly.

On the other hand, on the side wall surface 13 of the supporter 1, there is a magnet cover 16 for housing the magnet 15, and the magnetism of the magnet 15 is improved.

Further, the intermediate platform 12 is provided with wheels 17a, b, which are fitted onto the rails 2 (see FIG. 2) to make the movement of the support machine 1 smooth and stable.

As is clearer from FIG. 1, this supporting machine 1 is fixed to the conveying chain 3 by bringing the magnet 15 into contact with and attracting the plate 30 of the conveying chain 3.

As shown in FIG. 2, this conveyance chain 3 is made up of a plurality of plates 30 connected together, is movable left and right, and is adapted to convey the fixed support machine 1.

This conveyance chain 3 is preferably endless and configured to be able to circulate.

The rotating magnet 4 is provided at any position along the line of the conveying chain 3 so as to come into contact with the lower part of the metal rod 10.

Furthermore, the coating spray 5 is uniformly applied to the object 6 attached to the tip of the metal rod 10.

The rotary magnet 4 is provided in the vicinity of the rotating magnet 4 in order to apply the coating material.

In order to operate the coating apparatus according to the present invention, first, the object to be coated 4 is attached to the tip of the metal rod 10 of the supporter 1, and then the object to be coated 4 is attached to the tip of the metal rod 10 of the supporter 1. The provided magnet 15 attracts and fixes it.

In addition to this, a pair of rails 2 is provided on the top of the conveyor chain 3,
It is preferable that the wheels 17a and 17b of the support machine 1 be able to rotate on this rail 2.

Furthermore, if the upper end of the plate 30 of the conveyor chain 3 is fitted to the lower part of this rail 2 so that it can slide left and right, the support machine 1 can be moved stably and smoothly as the conveyor chain moves. .

The support machine 1 fixed to the conveyor chain 3 in this manner moves in the direction of the arrow in FIG. 2, for example, and the lower part of the metal rod 10 comes into contact with the rotating magnet 4 (FIG. 3).

As the conveyance chain 3 moves, the metal rod 10 that is in contact with the rotating magnet 4 is attracted by the rotating magnet 4 and rotates reliably. is painted evenly.

The coating device according to the present invention optionally includes a drying oven (not shown).
can be provided.

Similarly to FIG. 3, a rotating magnet 4 is placed on a metal rod 1 in a drying oven.
0, the object 6 to be coated will rotate in a drying oven (for example, a far-infrared drying oven) after painting, and the object 6 to be coated can be dried uniformly.

According to the coating device according to the present invention, the plate 3
Since the conveyor chain 3 in which a plurality of plates 30 are aligned is used, when the object 6 to be coated has a small size, one of the plates 30,
The support machine 1 is fixed to one without a gap, and the object 6 to be coated is
Plate 3, except for painting large dimensions.
It is now possible to suction and fix the support device 1 at every other or every two 0s, and the objects 6 to be coated can be attached at arbitrary intervals.
Since it can be transported, objects of any size and shape can be easily painted.

That is, after the object to be coated 6 is produced in small quantities, other objects to be coated 6 are produced.
When it becomes necessary to coat objects 6, it is possible to easily construct a line suitable for the objects 6 to be coated, which is extremely advantageous especially as a coating device for small-scale production.

Moreover, in order to rotate the metal rod 10 using the magnet 4,
Compared to a conventional rotation mechanism using gears, the moving distance of the conveyor chain 3 is shorter, and the metal rod 10 rotates once.

For this reason, complete painting is possible by using a single spray 5, which is not only extremely efficient, but also because it does not use a complicated mechanism like a gear, it is less likely to break down and is not only cheaper to manufacture. It has the advantage of requiring no maintenance and being extremely economical.

Further, since a magnet is used, the metal rod 10 has the effect of rotating reliably and stably.

Furthermore, by providing the rail 2, the conveyor chain 3
This has the advantage that the support machine 1 can be moved stably and smoothly.

As described above, according to the present invention, the workpiece 6 of any size and shape can be coated by the combination of the plate 30 provided on the conveyor chain 3 and the magnet 15 provided on the side wall surface 13 of the support machine 1. This has the great effect of not only being able to be painted easily and reducing manufacturing costs, but also providing products of uniform quality.
