Description

[Detailed Description of the Invention] The present invention particularly relates to a device for printing on objects exhibiting a curved surface, and more specifically, an apparatus for printing letters, designs, etc. on three-dimensional objects, particularly in the shape of a plate.
The present invention relates to a device for easily and efficiently applying a multicolor pattern to an article by heating and simultaneously receiving the pattern on a transfer pad, and then transferring the pattern from the transfer pad to the surface of the article.

2. Description of the Related Art Conventionally, an indirect printing device using an elastic body, a so-called octopus printing machine, has been devised as a device for printing characters, designs, etc. on various three-dimensional articles. This device is widely used because the ink medium ``octopus'' is highly elastic and can print well even if the surface to be printed is somewhat curved. For example, this octopus printing machine first receives ink on the plate, scrapes off the excess ink on the plate with a doctor, then allows the octopus to receive the ink on the plate surface, and then transfers the ink from the octopus onto the surface of the article. , to attach pictures to objects. However, when painting using such a device, the device requires one plate for each color of the design. Therefore, when painting multicolor designs, multiple plates are required, making the equipment complicated.
Become larger. In addition, it was necessary to perform color alignment, making it unsuitable as a device for painting multicolored designs.

On the other hand, as a method for painting multi-colored designs on various three-dimensional objects, a method of transferring designs from a transfer material has been devised, and an application has been filed by the present applicant for a painting device that applies this method (Utility Application 1983- No. 159557) Although this device compensates for the drawbacks of the octopus printing press, it still has the following problems. That is, since the transfer pad reciprocates in the horizontal direction, the time it takes for the transfer pad to stop vibrating before it is stamped becomes a loss time, making it impossible to shorten the time required for one printing process. Ta.

The inventor of the present invention completed the present invention as a result of various studies aimed at solving the problems of conventional devices as described above.

That is, the present invention has an article holder 1, a hole 2, a suction port 4 for holding the transfer paper 3 around the hole 2, a slide plate 5 that moves back and forth, and a slide plate 5 that is provided above the slide plate 5 and that moves up and down. A transfer pad 7 receives the design on the transfer paper 3 by pressing against the transfer paper 3, and then transfers the design to the surface of the article 6 by pressing against the article 6 on the article holder 1, and a slide plate 5. The hole 2 of the slide plate 5 is provided below and moves up and down.
A heating table 8 heats the transfer paper 3 adsorbed at the position of
This is a multicolor pattern painting device characterized by consisting of the following.

The present invention will be explained in more detail below based on the drawings. Figures 1 and 2 show an embodiment of the present invention. 5 is a slide plate, and this slide plate 5
There is an article holder 1, a hole 2, and a suction port 4 around the hole 2.
is provided, and the slide plate 5 reciprocates in the horizontal direction. The suction port 4 is for attracting and holding the transfer paper 3 at the position of the hole 2, and may be installed on the upper surface or the lower surface of the slide plate 5. When feeding the transfer paper 3 to the position of the hole 2, it may be done manually, or a paper feed section 9 may be provided. The paper feed section 9 is installed so that the suction port 4 comes above or below the paper feed section 9 when the slide plate 5 moves to the left. When the paper feed section 9 is provided above the slide plate 5, the suction port 4 is placed on the top surface of the slide plate 5, and when it is provided below the slide plate 5, the suction port 4 is placed on the bottom surface of the slide plate 5. (Third,
(See Figure 4) When the slide plate 5 holding the transfer paper 3 at the hole 2 position by the suction port 4 moves to the right and the transfer paper 3 is positioned above the heating table 8, the slide plate 5 provided above the slide plate 5 moves to the right. The transferred pad 7 is lowered, and at the same time, the heating table 8 provided below the slide plate 5 is raised.
As a result, the transfer paper 3 is heated and at the same time its design is brought into pressure contact with the transfer pad 7, and the design is received on the surface of the transfer pad 7. The transfer pad 7 is made of an elastic material such as silicone rubber. In the embodiment, the transfer pad 7 is connected to a shaft 10, and is moved up and down by means such as an air cylinder. Furthermore, when the transfer pad 7 and the pattern are pressed together, the upward movement of the heating table 8 is set so that the top surface of the heating table 8 is approximately at the same height as the top surface of the slide plate 5. This is preferable because the pressure of the pad is sufficiently applied to the pattern (see Figures 3 and 4).

When the transfer pad 7 receives the pattern on the transfer paper 3 and rises, the heating table 8 descends and the slide plate 5 moves to the left again. In the embodiment, the slide plate 5 is moved to the paper discharge section 1 while adsorbing the transferred transfer paper 3.
1, the suction of the suction port 4 is stopped there, and the transfer paper 3 is discharged.

As the slide plate 5 moves, the article holder 1 on which the article 6 is placed is positioned below the transfer pad 7.
In this state, the transfer pad 7 that has received the design moves down, transferring the design onto the surface of the article 6.

Regarding the vertical movement of the transfer pad 7, it is configured so that it moves up and down to different heights when it comes into pressure contact with the transfer paper 3 and when it comes into pressure contact with the article 6, in order to obtain the optimum pressure at the time of pressure contact. You can. In this case, the transfer pad 7 moves down periodically to two different heights alternately.

One step is completed as described above, and the suction port 4 of the slide plate 5 again holds the untransferred transfer paper 3 and is positioned below the transfer pad, and the same step is repeated. When repeating the process, slide plate 5
The movement of the transfer pad 7, the movement of the heating table 8, and the movement of the heating table 8 are configured to be performed in synchronization with each other.

The transfer paper used in this device is constructed so that the pattern becomes adhesive when heated and maintains this adhesive property for a certain period of time. That is, this transfer paper is made by applying a wax component in or under the pattern, which becomes adhesive when heated and then transferred to the surface of the transfer pad 7.
Furthermore, the design is transferred to the surface of the article while the adhesiveness lasts.

As described above, the present invention is a device that can transfer the design on the transfer paper onto the surface of the article at once, so by using this device, it is possible to easily apply multicolor designs. Furthermore, since the transfer pad moves only in the vertical direction, the time required for one process can be shortened and productivity can be increased. Further, since there is little vibration of the transfer pad, it is easy to transfer the design onto the article more accurately. Therefore, the multicolor pattern painting device according to the present invention is expected to be widely used in painting ceramics, plastic molded products, and various other articles.
