Description

The ink supply-recovery device of a flexographic press}

The present invention relates to a printing press, and more particularly, to an ink supply recovery device of a curved surface printer for supplying and recovering ink to a flexographic press (FLEXOGRAPHIC PRESS).

The curved printing machine is provided so as to be suitable for printing in the case where the thickness of the to-be-printed material is thick, such as corrugated cardboard used as a main material for packaging boxes and the like.

FIG. 5 is a cross-sectional view of the ink supply recovery device of the conventional curved printing press, and FIG. 6 is a cross-sectional view taken along the line C-C of FIG. 5, and its configuration and operation are as follows.

Reference numeral 100 denotes an application roller for supporting both sides of the longitudinal direction on the support base 101 and for applying ink to the typesetting.

On the horizontal side of the application roller 100, an auxiliary application roller 102 for uniformly distributing ink on the surface of the application roller 100 while rotating in surface contact with the application roller 100 is provided.

An imposition holding roller 103 is provided at the lower portion of the application roller 100 and an imposition support for advancing the imprinted material while adhering the imposition to the imposition at the lower portion of the imposition holding roller 103. The roller 104 is provided.

An ink supply hose 105 for supplying ink between the application roller 100 and the auxiliary application roller 102 is installed at an upper portion between the application roller 100 and the auxiliary application roller 102 and the application roller 100. And a recovery hopper 106 of a grind to recover surplus ink or washing water supplied between the application roller 100 and the auxiliary coating roller 102 at the lower ends of the longitudinal ends between the auxiliary coating roller 102 and the auxiliary coating roller 102. And the lower part of the recovery hopper 106 is connected to the collection container (T).

In addition, the coating roller 100, the typesetting holding roller 103 and the to-be-supported roller 104 can be rotated by the same rotational distance by a transmission means (not shown) such as a gear or a chain.

When printing using the conventional curved surface printing machine as described above, as shown in FIG. 6, the typesetting sheet 107 inscribed with the shape to be printed is fixed to the typesetting sheet 108 and the typesetting sheet 108 is held. The transmission means is operated while being wound and fixed on the roller 103.

When the transmission means is operated, ink is supplied from the ink supply hose 105 between the application roller 100 and the auxiliary application roller 102, and the supplied ink rotates while the application roller 100 and the auxiliary application roller 102 contact each other. By this, the ink is uniformly applied to the surface of the application roller 100 and the ink applied to the application roller 100 is uniformly applied to the surface of the typesetting 107 fixed to the typesetting holding roller 103.

When the to-be-printed object 109 is supplied between the typesetting holding roller 103 and the to-be-supported roller 104 in the above state, the to-be-printed material 109 is printed by the ink applied to the typesetting 107. The printed object to be printed 109 is guided to another curved printer by the object guide roller 110 installed in close proximity to the object support roller 104 to print different colors.

In addition, in the ink supplied between the application roller 100 and the auxiliary application roller 102 during the printing process, the surplus ink deviating from the front end portions of the sliding surfaces of the application roller 100 and the auxiliary application roller 102 is a recovery hopper ( 106 and collected in the collection container (T).

On the other hand, in order to print a different color after the printing operation of a predetermined color as described above through the ink supply hose 105 to supply the wash water between the coating roller 100 and the auxiliary coating roller 102 by applying the coating roller 100 And wash the ink on the auxiliary coating roller 102 and the washing water generated at this time is dropped into the recovery hopper 106 as described above is collected by the collection container (T).

The conventional curved printer as described above has no problem in the process of printing a predetermined color on the object to be printed. However, since there is no means for preventing the surplus ink from flowing out of the sliding surface of the coating roller 100 and the auxiliary coating roller 102, there is a problem that the peripheral components are contaminated by the surplus ink flowing down the sliding surface. In addition, since there is no means for removing the ink from the coating roller 100 and the auxiliary coating roller 102 other than the washing water, a large amount of washing water is generated, which requires a considerable cost for the treatment of the washing water and of course, environmental pollution. will be.

The present invention has been devised in view of the above-mentioned conventional problems, and its object is to surplus the sliding surface of the coating roller and the auxiliary coating roller by blocking both end faces in the longitudinal direction of the coating roller and the auxiliary coating roller. By preventing the ink from flowing down, it is possible to prevent the contamination of surrounding components by the ink and to reduce the cost of washing water by allowing the ink on the application roller and the auxiliary coating roller to be cleaned with a small amount of washing water. It is, of course, to provide an ink supply recovery device for a curved surface printer that can actively prevent environmental pollution.
