This invention relates to an automatic painting device for painting with a printing plate.

(Prior Art) As a conventional technology, there are automatic painting devices that only paint the front surface of ceramic products, and automatic painting devices that paint only the back surface of ceramic products.

(Problems to be Solved by the Invention) In the above-mentioned conventional technique, since the front side painting and the back side painting are performed separately, there is a particular drawback that the work efficiency is extremely low. Therefore, this invention aims to improve work efficiency by making it possible to perform front side painting and back side painting at the same time, and also to make it convenient for use by making it possible to perform only either front side painting or back side painting. The present invention provides an automatic painting device for ceramic products and the like.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides front printing plates 2 on the upper and lower sides of the base 1 on which the product A to be painted, such as ceramics or synthetic resin, is placed. A back printing plate 3 is provided, and the front printing plate 2 is driven by a driving source 4 such as an air cylinder.
The stamp is moved back and forth in the lateral direction, and is alternately opposed to the base plate 1 and the front stamp mounting base 5. Painted surface a of product A such as ceramics or synthetic resin placed on it
The stamp 7 for the front stamp set on the stamp mounting base 5 for the front stamp is moved forward and backward by a preset constant stroke, and the back stamp 3 is driven by a drive source 8 such as a rotary actuator. Therefore, the product A, such as ceramics or synthetic resin, placed on the base plate 1 by the driving source 10 such as an air cylinder is placed on the base plate 1 and the stamp mounting base 9 for the back printing plate alternately inverted and opposed to each other at each opposing position. It is characterized in that it is provided so that it can be moved forward and backward by a preset constant stroke toward the back side painting surface a' and the back stamp stamp 11 installed on the back stamp mount 9. It employs technical means.

(Function) By employing the above technical means, the present invention provides a front printing plate 2 and a back printing plate 3 disposed above and below the base plate 1.
The front painting side a and the back painting side of product A such as ceramics or synthetic resin to be painted placed on base plate 1
a' and stamp 7 for the front stamp and stamp 1 for the back stamp
1 and move forward and backward by a preset constant stroke, the front and back printing plates 2, 3 can simultaneously paint the painting surfaces a and a', and the front and back printing plates 2, 3. Paint (pigment) can be applied efficiently to the surface, and if one of the front printing plate 2 and the back printing plate 3 is stopped, only the front surface painting or the back surface painting can be performed.

The back printing plate 3 is attached to the mounting base plate 25 via the support bracket 26, and the rotary exciator 8
It can be turned over by 180°C. This back printing plate 3 may be one back printing plate 3 as illustrated in FIG. 3, or two back printing plates 3, 3' arranged in opposite directions as shown in FIGS. 1 and 2. established,
The air cylinders 10 and 10' may be used to move forward and backward simultaneously or alternately. Reference numeral 5 denotes a stamp mount for the front seal plate, which is provided on the other side of the housing B. On the stamp mount 5 for the front seal plate, a stamp 7 for the front seal plate soaked with paint is installed. Reference numeral 9 denotes a stamp mounting stand for the back printing plate, which is provided in the housing B at the bottom of the base plate 1, and a stamp 11 for the back printing plate soaked in paint is installed on the stamp mounting stand 9 for the back printing plate. It's forcing me. A control box C is fixed to one side of the housing B, and controls the vertical movement stroke of the front seal plate 2 by the air cylinder 6, the left and right movement speed of the air cylinder 4, and the respective operating speeds, etc. This is to control the vertical advance and retreat stroke of the plate 3 by the air cylinder 10, the reversal operation by the rotary exciator 8, and the speed of each movement.
The program can be freely set depending on the size, shape, etc. In addition, front seal version 2
If an intaglio plate with a soft silicone rubber pad is used for the back printing plate 3, the product A of ceramics or synthetic resin etc.
Because the paint can be freely deformed and transferred along the shapes of the front and back painting surfaces a and a', it is possible to print on uneven or three-dimensional curved surfaces, which was considered impossible with conventional printing methods, making it possible to print on delicate surfaces. Patterns and text can be printed clearly and precisely. 27 is an arm that supports the guide rail 17; 28 is a rotary exciator 8;
The bearing 29 of the rotating shaft 24 is a swivel wheel.

In the above configuration, when a product A such as ceramics or synthetic resin to be painted is automatically or manually placed on a predetermined position on the base plate 1, the detection sensors 12, 12' sense this and notify the control box C.
First, the front and back printing plates 2 and 3, which are waiting facing the front and back printing plate stamps 5 and 11, are linearly moved up and down by a preset constant stroke by the air cylinders 6 and 10. Then apply paint to the front printing plate 2 and back printing plate 3 (see arrows b and 3 in Figure 1).

The surface painting surface a of product A, such as ceramics or synthetic resin, is moved by a certain stroke to the left in the illustration.
The back printing plate 3 is rotated 180 degrees counterclockwise in the drawing by the rotary exciator 8, and is positioned directly below the back side painting surface a' of the product A, such as ceramics or synthetic resin. The printing plates 2 and 3 on the back face each other toward the front and back painting surfaces a and a' of the product A, such as ceramics or synthetic resin, which is placed on the base 1 (Fig. 1). (see arrows c and e). After that, the front and back printing plates 2,
3 simultaneously advances and retreats vertically in a straight line by a predetermined stroke, and applies the ceramic or synthetic resin product A to the front painted surface a and the back painted surface a' of the ceramic or synthetic resin product A. Apply the desired painting while sandwiching A (arrow d in Figure 1).
After that, the front stamp plate 2 is moved by a certain stroke to the right in the figure by the air cylinder 4 and stops directly above the front stamp stamp 7, and the back stamp plate 3 is moved by the rotary erector 8. Clockwise direction as shown
It is rotated 180 degrees and positioned directly above the stamp 11 for the back printing plate, and is on standby in preparation for the next painting operation. In the meantime, automatically or manually remove the painted ceramic or synthetic resin product A on the base plate 1,
The product A to be newly decorated, such as ceramics or synthetic resin, is placed on the base 1, and then the next painting operation begins according to the above-mentioned principle.

The above series of painting operations are carried out smoothly and reliably according to a program set in advance by control box C.
In the case of In the case of plates 3 and 3' (see Figures 1 and 2), the position where the back printing plates 3 and 3' are inverted and oriented toward the upper and lower ceramic or synthetic resin product A and the back printing plate stamp 11. move forward and backward at the same time or alternately (see arrows f and f' in Figure 1),
The work efficiency can be improved compared to the case where only one back printing plate 3 is used, but in this case, the movement of the front printing plate 2 should be adjusted to match the movement of the back printing plates 3 and 3'.
Conversely, the movement of the back printing plates 3, 3' is adjusted in accordance with the movement of the front printing plate 2.

Furthermore, when painting only on the back painting surface a' of product A such as ceramics or synthetic resin, the operation of front printing plate 2 is stopped by a command from control box C, and the ceramic product A is If, on the other hand, you want to lightly hold the plate and paint only on the front painting surface a, simply stop the operation of the back printing plate 3 with a command from the control box C, and each can be painted individually.

(Effects of the Invention) As explained above, this invention uses a front printing plate and a back printing plate placed on the top and bottom of a base on which a product such as ceramics or synthetic resin to be painted is placed, so that the surface to be painted can be painted on the surface of the product. Painting on the reverse side The desired painting can be done simultaneously in one movement, so all you have to do is automatically or manually by one worker to load and unload products such as ceramics or synthetic resin onto the base plate at a certain timing. This allows efficient painting work to be performed automatically. In addition, it is also possible to perform front side painting and back side painting separately, so this invention has unprecedented effects in actual use.
