Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides horizontal movement of at least one pair of transfer plates between a ceramic setting device and a printing device disposed adjacent to both sides of a transfer device installed at the same position below. This transfer plate is screen printed using a printing device, and with the printing side facing upward, the transfer plate is moved directly below the ceramic setting device.
The present invention relates to a ceramic transfer printing device (hereinafter simply referred to as a transfer printing device) in which a transfer device is used to print on printed materials such as ceramics.

Conventionally, the above-mentioned transfer printing apparatus includes, for example, the one described in Japanese Patent Publication No. 49-35882.

However, the above conventional method has the following drawbacks.

a) The ceramics setting device uses a turntable, and the ceramics are placed in a fixed position on the table surface with the surface to be transferred facing upward, and the ceramics are placed through the transfer plate and the elastic pad. Since the mechanism is such that transfer printing is performed from above, it is necessary to turn over the transfer plate after the paint has been supplied while it is being moved to the ceramic position on the turntable surface.

For this reason, the above-mentioned turning device is required for each transfer plate, making the structure of the entire device complex and prone to frequent failures.

b. If you try to perform transfer printing with two or more different colors of paint on the ceramic surface of the turntable, you will not only have to install a separate transfer printing device for each color, but you will also have to do more printing work. This becomes troublesome and requires a lot of effort.

c. Also, on an elastic thin film, etc., an ink layer for displaying an arbitrary pattern is applied by screen copying, and this is reversed to face the transfer surface below the ink layer, and a pressing member made of an elastic body is applied to the transfer surface. There is a screen printing method that transfers the ink by pressing it onto the screen, but with this type of screen printing method, the ink layer must be reversed for printing, which requires a lot of effort, and when the printed parts are overlapped, they tend to shift. It has the following disadvantages.

d Furthermore, there are stamp-type printing plates, in which a pair of plates are moved forward and backward in a straight line, and printing is performed by alternately facing the transfer surface of the ceramic product, but this is because the printing plate is Since it is a stamp type, it has drawbacks such as being limited to the shape of the printing surface and printing of fine-grained patterns.

Therefore, the purpose of this invention was to improve the above-mentioned drawbacks of the previous one in a very simple and effective manner, and it was successful in this. First, the gist of this invention will be explained as follows. It is.

That is, the present invention provides a horizontal rail along the longitudinal direction of the upper part of a horizontally long base, and uses a horizontal movement device to move at least a pair of transfer plates, each of which has an elastic sheet for transfer stretched on a movable frame onto the rail. A transfer device is disposed approximately in the center of the rail to face one of the transfer plates below the rail, and is adjacent to both sides of the transfer device, and
A printing device comprising a screen for printing a pattern made of muddy paint onto the elastic sheet surface of the transfer plate, and an elevating pad with a flat top surface designed to stably support the elastic sheet surface from below during printing via a squeegee. A ceramic setting device is arranged above the transfer device and facing the transfer device to sequentially set the transferred ceramics in a fixed position, and further, the transfer device is placed in the position of the printing device by the printing device. The elastic sheet of the transfer plate that is transported and arrives with the printed surface facing upward is pressed against the transfer surface of the ceramic using an elevating elastic pad;
The gist of the transfer printing device is that the transfer plate on the path is configured to reciprocate between the transfer device and the printing device at appropriate times.

In order to further clarify the above-mentioned gist of the present invention and to specifically explain the structure and effects of the present invention, an embodiment of a transfer printing apparatus according to the present invention will be given and will be described in detail with reference to the drawings as follows. It is as follows.

It goes without saying that the present invention is not limited to the following examples.

That is, in the figure, 1 is a horizontally long base, 2 is a rail installed horizontally along the longitudinal direction of the base on the top of the base, and P is installed at a position corresponding to the longitudinal center of the rail. The transfer device Q is also a ceramic setting device, R and Ra are printing devices fixedly installed on the rails on both sides of the above transfer device P, and S,
Both Sa are transcription versions.

Next, each of the above devices will be explained.

First, the transfer plates S and Sa have the same structure, so to explain only the transfer plate S, this transfer plate has a movable frame 3 that moves horizontally forward and backward on a rail 2, This movable frame is provided with an elastic sheet 4 for transfer stretched horizontally, and the elastic sheet 4 is made of thin synthetic rubber, and the surface of the sheet is covered with a thin silicone resin film. (not shown).

The transfer plate S can be moved forward and backward between the transfer device P and the printing device R at a timely manner by means of a cylinder 5 provided on the outside of the base 1. The transfer plate Sa can also be moved forward and backward between the transfer device P and the printing device Ra by the above-mentioned cylinder 5, and when the transfer plate S is at the position of the transfer device P, the transfer plate Sa is located at the position of the printing device Ra, and the transfer plate is also
When Sa is at the position of the transfer device P, the transfer plates S are moved forward and backward together via the cylinders 5 described above so that they are respectively oriented at the positions of the printing device R.

Furthermore, since both printing devices R and Ra have the same structure, explaining only the printing device R, this printing device R has the following structure.
A fixed frame 6 is fixed horizontally at a fixed position above the advance/retreat path of the movable frame 3, and is stretched horizontally to this fixed frame, and a muddy paint (not shown) is applied to the upper surface at appropriate times. There is a printing screen 7 that is supplied, a squeegee 8 that slides on this screen, and a squeegee 8 that is located below the screen 7 and has a flat top surface and is moved up and down by a cylinder 9 at the appropriate time. A printing pattern (not shown) is provided on the screen 7 surface, and a squeegee 8 is slid over the screen 7 surface with a cylinder 11 at appropriate times. The transfer plate S, which moves horizontally, keeps a slight gap between the upper surface of the elastic sheet 4 and the lower surface of the screen 7, and stops at a fixed position below the screen 7. There is.

When the transfer plate S stops, the pad 10 is raised by the cylinder 9 to stably support the elastic sheet 4 of the transfer plate from below, and at the same time, the squeegee 8 slides on the surface of the screen 7.
The pattern of the screen 7 is printed on four sides of the elastic sheet of the transfer plate. In addition, the printing device
As described above, Ra has the same structure as the printing apparatus R, and is configured to print exclusively on the transfer plate Sa.

Furthermore, the muddy paints used in each of the printing apparatuses R and Ra are of different colors.

Furthermore, the ceramic setting device Q has one end in the longitudinal direction as a fulcrum 12, and this fulcrum is placed in the center of the upper surface of the base 1, and rotates back and forth 180 degrees at appropriate times in a direction perpendicular to the advance/retreat direction of the transfer plate. arm 13
and is fixed to the other end of this arm 13,
It is equipped with a holder 15 that removably holds the ceramic ware 14 stably with a vacuum chuck (not shown), and a motor 16 that imparts the above-mentioned rotation to the arm 13. Ceramics 1 held by ceramics setting device Q
4, at the time of transfer, at the stop position of the transfer plates S and Sa in the transfer device P, which will be described later, the normal position M is immediately above the transfer plate stopped at that position, and at the time of reversal after transfer, One side of the base 1 is set as its home position N.

Furthermore, the transfer device P is installed below the above-mentioned ceramic setting device Q, and is equipped with an elastic pad 17 for transfer and a cylinder 18 for raising and lowering this elastic pad 17 at the appropriate time. The upper surface of the elastic pad 17 is a fitting surface 19 adapted to the shape of the lower surface (transferred surface) of the ceramic 14 in the fixed position M, and one of the transfer plates S and Sa is in the above-described position. When it stops just below position M, it rises through the cylinder 18, pushes up the elastic sheet of the transfer plate from below, and removes the ceramic 14.
It is designed to be pressed against the lower surface (transferred surface) of the

The cylinders 5 for horizontally moving the transfer plates S and Sa, the cylinders 9 for raising and lowering each pad in the printing devices R and Ra, the cylinders 11 for sliding the squeegee 8, and the motor 1 for the ceramic setting device Q.
6, and a cylinder 18 for lifting and lowering the elastic pad 17 in the transfer device P, both of which are adjusted by a separately provided control device (not shown), are used to transfer the transfer plates S, Sa, which have been printed on the elastic sheet surface. When one of them stops directly below the fixed position M of the ceramic 14 above the transfer device P, the elastic pad 17 in the transfer device P rises and transfers the elastic sheet of the transfer plate above to the transferred object of the ceramic 14. While this is pressed onto the surface to perform the transfer, the arm 13 of the ceramic setting device Q is then rotated 180 degrees, and at the fixed position when it is reversed, the ceramic 14 is replaced with a new one.

The transfer plate, which has completed the transfer as described above, is guided by the rail 2 and moved to the position of one of the printing apparatuses R and Ra for the time being, and printing is performed again at that position. At this time, at the fixed position M, transfer is performed on a new 14th surface of the ceramic using another transfer plate. Furthermore, numeral 20 shown in the drawings represents a guide rail for the squeegee.

With the above-described transfer printing device, in order to move the transfer plates printed on the elastic sheet surfaces in each of the printing devices R and Ra to directly below the ceramic fixed position M in the ceramic setting device Q, screen printing is required. Since it is only necessary to move the printing section horizontally with the printing section facing upward, the transfer position is accurate and the pattern does not shift, and the overall structure of the device is significantly simpler than previous models, reducing the chance of failure. In addition to being able to perform transfer printing efficiently with less noise, printing equipment R, Ra
By making the patterns on both screens a two-color printing pattern, it is now possible to transfer the pattern using two-color paint onto the transfer surface of the ceramic 14, which is more convenient and has greater utility than the previous method. becomes.

In this invention, the shape, structure, etc. of the transfer plate, the horizontal movement device, the path, the printing device, the ceramic setting device, and the transfer device may be appropriately determined as long as the above-mentioned object of the invention is achieved. Needless to say, it is a good thing.

As will become clear from the above description, according to the present invention, the above-mentioned drawbacks occurring with respect to the previous ones are improved very simply and effectively, so that the practical benefits brought about by the present invention are I have to say it's huge.
