Description

Printing apparatus having automatic paper feeder {Printing apparatus}

The present invention relates to a printing apparatus having an automatic printing paper feeder.

More specifically, the present invention relates to a printing apparatus having a printing paper automatic feeder, which is capable of increasing mass productivity by providing an automatic feeder for automatically supplying and collecting printing paper.

Rotational printing has attracted attention as a method for mass-producing electronic devices such as RFID, polymer transistors, flexible displays, and solar cells. Such a rotary printing is suitable for mass production because the printing speed is high because the printing roll can be continuously and repeatedly printed on the printing paper while the roll is rotating.

1 is a view showing an example of a conventional rotary printing apparatus.

According to FIG. 1, a conventional rotoprint apparatus includes at least an electronic device on an unwinder 2 for supplying a printing paper 1, and at least an electronic device on the printing paper 1 fed from the unwinder 2. It is composed of at least one printing machine 3 and a rewinder 4 which rewinds the printing paper 1 which has been printed by the printing machine 3.

In the conventional web printing apparatus, since the unwinder and the rewinder are arranged inline, not only the volume of the entire apparatus is increased but also the distance between the unwinder and the rewinder is long, so that it is difficult to separate print paper or maintain a constant tension. The design requirements are very demanding, as control devices must be installed to control this. This leads to problems such as high production costs and low productivity.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, the main object of the present invention is to efficiently arrange the printing machine and the automatic printing paper feeder to reduce the size of the printing device, unwinding roll and rewinding The present invention provides a printing apparatus having a printing paper automatic feeder which does not necessarily have to install accessories for preventing separation of printing paper and tension control due to the distance between rolls.

Main features of the present invention for achieving the above object,

Base; A moving stage in a state capable of linearly moving along the base and having a flat plate on which a printed pattern is formed; A printing provided on the moving stage and having an unwinding roll for supplying printing paper, a rewinding roll for recovering printing paper, and a plurality of guide rolls for guiding the printing paper through the printing zone of the moving stage. Paper feeder; And a printing roll installed on the base and configured to transfer a printing ink embedded in the printing pattern of the flat plate onto a printing sheet positioned on the moving stage.

The present invention has the effect of reducing the overall volume of the printing apparatus by efficiently improving the arrangement of the printing machine and the printing paper automatic feeder.

In addition, as the gap between the unwinding roll, the printing press, and the rewinding roll is reduced, there is little risk of the printing paper falling off and the tension change is small, thereby improving the reliability of printing. Accordingly, it is not necessary to install control devices for preventing separation and tension of printing paper, so that the design of the device is easy and the production cost is low, thereby increasing the productivity of the device.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The engraving roll 50 is to be used for a limited time during the roll engraving, the negative printing pattern is formed on the outer peripheral surface. The plate making roll 50 is elevated by the second elevating member 51 above the printing roll 40 of the bracket 11 and is in a state capable of rotating by the second rotating motor 52.

Unexplained reference numeral 70 is an ink container which supplies ink to the flat plate 21 and removes ink stuck to a place other than a printing pattern formed on the flat plate 21. In addition, a separate ink container for supplying ink to the engraving roll 50 at the time of roll forming can be further provided.

Hereinafter, the operating process of the printing apparatus of the present invention configured as described above will be briefly described, with reference to the flat plate.

After the printing paper 1 is set in the printing paper automatic feeder 30, the moving stage 20 is moved so that the printing pattern formed on the flat plate 21 is positioned under the ink container 70. The moving stage 20 is repeatedly moved from side to side within a predetermined clearance range to inject the ink from the ink container 70 into the printing pattern.

Next, the moving stage 20 is moved in one direction so that the flat plate 21 seated thereon is positioned under the printing roll 40.

Next, the printing roll 40 spaced apart from the flat plate 21 is lowered to bring the printing roll into contact with the printing pattern of the flat plate 21.

Next, the moving stage 20 is moved in the ink container 70 direction, and the printing roll 40 is rotated in synchronism with this to transfer the ink contained in the printing pattern onto the surface of the printing roll 40.

Next, when the transfer of the ink pattern on the surface of the printing roll 40 is completed, the printing roll 40 is raised to be transferred to the flat plate 21, and then the printing roll 40 is reversed from the rotational direction in the transfer process. Direction to return the printing roll to the origin.

Next, the moving stage 20 is moved in the direction of the ink container 70 so that the printing surface 1 printing surface is positioned under the printing roll 40.

Next, the printing roll 40 spaced apart from the printing sheet 1 is lowered to bring the printing roll 40 into contact with the printing sheet 1.

Next, the moving stage 20 is moved in the ink container 70 direction, and the printing roll 40 is rotated in synchronism with this to transfer the ink deposited on the surface of the printing roll 40 onto the printing surface of the printing paper 1. .

Next, the unwinding roll 32 and the rewinding roll 33 are rotated together so that the printing portion of the printing paper 1 is completed on the rewinding roll 33 and a new printing surface is printed on the moving stage 20. It is located at (20a).

When the transfer printing is completed, the printing roll 40 and the moving stage 20 are returned to their original positions, and then the printing process is repeatedly and continuously performed.
