Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gravure printing cylinder or a printing cylinder such as a coating cylinder for coating a coating liquid, which is immersed in the printing coating liquid to supply the printing coating liquid to the cylinder. The present invention relates to a coating liquid supply device.

[0002]

2. Description of the Related Art A printing coating cylinder is immersed in a printing coating liquid stored in a printing coating liquid supply tank and rotated,
In the conventional supply device for supplying the print coating liquid, it was used only for supplying the print coating liquid to the print coating cylinder.

In such a conventional printing coating liquid supply apparatus, when the printing coating cylinder is removed from the main body of the printing coating apparatus and replaced after the printing coating is completed, printing ink liquid, coating liquid, etc. are supplied from the supply tank. After discharging to the outside or before discharging, temporarily move the supply tank forward or backward from below the printing coating cylinder and evacuate it, and then carry in the transport vehicle with a lifting support table directly below the printing coating cylinder. Then, the upper surface of the support table is raised to be brought close to the lower circumferential surface of the body, and a rotary shaft (a shaft chuck with a taper cone) that fits in the recessed portions on both ends of the body and axially supports the body is attached. Then, the both ends of the body are retracted outwardly, the rotary shaft is separated from the recessed portions at both ends of the body, and the body is placed on the support base.

Subsequently, the transport vehicle on which the cylinder is placed is carried out from the print coating device, and after carrying out, a new cylinder for replacement is carried into the print coating unit of the main body of the print coating device by the transport vehicle. It was attached to the main body of the device.

When the printing coating liquid in the supply tank is replaced when the cylinder is removed and replaced, the liquid is discharged from the supply tank, washed with a solvent, etc., and then another printing ink liquid or coating is applied. A printing coating liquid such as liquid is filled in the supply tank.

[0006]

In the work of replacing the printing coating cylinder in the above-mentioned conventional printing coating liquid supply apparatus, the supply tank is moved outward from the position directly below the printing coating cylinder every time the printing coating cylinder is removed and attached. We are performing work to evacuate, and every time we remove the cylinder when replacing it, we carry in an empty carrier just below the cylinder and carry it out. Every time the cylinder is attached during replacement, the cylinder is carried into the printing coating unit of the machine body.After mounting the cylinder, the printing liquid supply tank is returned from the retracted position to the original position. In addition, when the printing coating liquid is replaced every time the cylinder is replaced, the supply tank is washed on the machine of the main body of the printing coating device each time.

In this way, the conventional printing coating cylinder replacement work is
Since it is carried out after a considerably complicated work process, simplification of the process has been desired.

According to the present invention, there is provided a print coating liquid supply apparatus for a print coating apparatus, which comprises a supply tank for moving and retracting the supply tank, removing and carrying out the cylinder, and carrying in the cylinder with the carrier. An object of the present invention is to simplify the work of replacing the printing coating cylinder and the work of replacing the printing coating liquid by enabling the work of returning to the original position to be performed at the same time.

[0009]

According to the present invention, when a printing coating cylinder such as a gravure printing plate cylinder or a resin liquid coating roller is detached from or attached to the main body of the printing coating apparatus and replaced, the printing coating solution supply tank and the carriage are replaced. Since it is configured integrally, the supply tank can be moved up and down, the body can be lifted and supported by the supply tank, and the supply tank and the body can be integrally moved and transported by a dolly. By doing so, the printing coating liquid can be exchanged together, and the cylinder exchange work and the printing coating liquid exchange work that have been performed through complicated processes as in the past can be simplified.

Further, since the ink liquid cleaning and replacing work in the supply tank after removing the cylinder can be carried out at a separate position separately from the main body of the printing applicator, after the replacement and installation work of the cylinder is completed,
It is possible to immediately shift to the printing application work, and to exert a remarkable effect in improving the efficiency of the cylinder replacement work and the printing coating liquid cleaning replacement work in the printing application work.
