Abstract

PURPOSE:To obtain a manufacturing equipment, in which the pattern to be printed is changed easily, by a constitution wherein the equipment concerned consists of a drawing device for drawing pattern to be printed on pre-painted steel plate, an image outputting device for outputting the pattern drawn with the drawing device in the form of transfer paper and a heat transferring device for transferring the pattern printed on the transfer paper onto the pre-painted steel plate. CONSTITUTION:The original of pattern to be printed onto pre-printed steel plate 5 is read with a figure reading device 1. The original read with the device 1 is corrected with a drawing device 2. The pattern drawn with the drawing device 2 is outputted in the form printed onto transfer paper 6 with an image outputting device 3. After that, the pattern drawn onto the transfer paper 6 is transferred onto the pre-painted steel plate 5 with a heat transferring device 4. Even when the production of the steel plate concerned is multikind and small quantity production, the manufacturing equipment of printed pre-painted steel plate, with which high quality printed pre-painted steel plate can be produced with almost no development of demerit on cost, can be obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing prepainted steel sheet manufacturing apparatus, and more particularly to a high quality printed prepainted steel sheet manufacturing apparatus for household electric appliances and household products manufactured in small lots and a wide variety of products. .

[0002]

2. Description of the Related Art A printing device for printing on a steel sheet is disclosed in Japanese Patent Laid-Open No. 59-951.
As described in Japanese Patent Publication No. 43, on a coated surface of a coated steel sheet, a ready-made transfer paper in which a heat-melting ink is printed on one side in advance is overlaid, and transferred by heating and pressing with a heating roll machine,
The predetermined pattern was printed in multicolor on the painted surface.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the apparatus of Japanese Patent No. 5143, the apparatus for creating an arbitrary pattern is not included in the apparatus, and therefore the transfer paper used for printing must be prepared in advance, and the pattern to be transferred is changed. When you do, it is necessary to replace the entire transfer paper used for printing, so it takes time to change the design,
Since waste will also occur on transfer paper, production efficiency will be poor and cost will increase unless a large amount of the same pattern is printed continuously.
It is not suitable for the production of printed prepainted steel sheets that can be used in small quantities and in a wide variety of products such as outer panels for home appliances.

[0004]

The present invention advantageously solves the above-mentioned problems of the prior art, and its gist is as follows.

1. Prepainting A printing prepaint consisting of an image drawing device that draws the design to be printed on the steel plate, an image output device that outputs the design drawn on the drawing device as transfer paper, and a thermal transfer device that transfers the design printed on the transfer paper to the prepainted steel plate. Steel plate manufacturing equipment.

2. A figure reading device that reads the original image of the pattern to be printed on the prepainted steel plate, an image drawing device that processes the read original image into a printed pattern, an image output device that prints the pattern drawn by the image drawing device on transfer paper, and a transfer A printing prepainted steel plate manufacturing device that consists of a thermal transfer device that transfers a pattern drawn on paper to a prepainted steel plate.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the apparatus shown in FIG.

The figure reading device 1 is for reading a ready-made pattern and inputting it to the drawing device 2. The drawing device 2 is for drawing a pattern to be printed on the prepainted steel plate 5. Further, it has a function of correcting the figure read by the figure reading device. The image output device 3 is
The thermal transfer device 4 is for creating the transfer paper 6 in which the pattern drawn by the drawing device 2 is drawn with the heat sublimable ink.
Is for thermally press-bonding the prepainted steel plate 5 and the transfer paper 6 created by the image output device 3 to thermally transfer the design drawn on the transfer paper on the coating surface of the prepainted steel plate. It has the function of adjusting the temperature and pressure at the time.

[0009]

Function: An arbitrary pattern to be printed on the prepainted steel plate 5 is drawn by drawing it with the drawing device 2 such as a computer. Further, it is also possible to prepare an original plate on which an arbitrary design pattern to be printed is drawn, read the design pattern of the original plate by the figure reading device 1 and input it to the image forming device 2 for image formation. If there is a correction to the design, the drawing device 2
You can also change the color and so on. The image output device 3 draws the design pattern drawn by the image drawing device 2 with thermal sublimation ink and outputs it as the transfer paper 6, and the transfer paper printed by the thermal transfer device 4 incorporated in the device. By thermally press-bonding 6 and the prepainted steel plate 5, an arbitrary pattern to be printed is transferred from the transfer paper to the coating film surface of the prepainted steel plate to produce a printed prepainted steel plate.

Since an image drawing, figure reading, and image output device are incorporated in the system, a figure to be printed is newly drawn or an arbitrary pattern is copied and drawn, and the image of this pattern is easily output. It is very easy to change the design because it is possible. Furthermore, since the design printing on the prepainted steel plate is performed by thermal transfer using heat sublimable ink, ink bleeding, printing defects such as color cast do not occur, and the design drawn on the transfer paper is beautiful and accurate. It is an apparatus for producing printed prepainted steel sheets, which is characterized in that the finished printed prepainted steel sheets are of high quality because they can be copied.

[0011]

As described above, according to the present invention, it is possible to produce a high-quality printed prepainted steel sheet with almost no cost demerit even for the production of a large number of small quantities. A manufacturing apparatus can be provided.
