Device for inking the painting roller of a

Printing press

-The invention relates to a device for coloring "the Inking roller of a printing press, with an ink shipping or ink reservoir provided on a movable carriage in the longitudinal direction of the inking roller and the outlet opening of the! arbbehälters assigned an outflow element for the paint is. "■■ · '-

Difficulties arise with such inking machines when removing the paint from the paint container as well "when applying the paint -. on the inking roller and" when applying the paint evenly Distribute the color in the longitudinal direction of the inking roller. These difficulties are due to the fatty or syrupy type Consistency of color. That is why one tries to

transferring the paint to another at the place of consumption Avoid containers as much as possible, as decanting is a messy and time-consuming process due to the viscosity of the paint.

The even distribution of color along the length of the In the above-mentioned device known from German Patent 667 629, the inking roller is effected by and the transfer of the paint avoided by the fact that the paint shipping or storage container on a longitudinal direction of the Inking roller is arranged sliding sehlitten «

In this known device, however, it is disadvantageous that the color only emerges under the effect of its own weight flows out of the paint container; the amount of color outflow cannot be influenced, so that the coloring process is time-consuming.

It is also known from the patents 2305 ° and 25340 of the Office for Invention and Patents, the paint transport container to avoid time-consuming and dirty transferring into the printing machine. Here is the outflow opening of the ink container facing the ink roller and in the outlet opening is a roller mounted in the container wall provided which closes the outlet opening and removes paint when rotated Ia paint container. One with this lock roller cooperating scraper device, also arranged in the outlet opening of the paint container, e.g. Squeegee or roller, should regulate or regulate the amount of ink carried out.

To squeeze
dose. Atiei £ üka? EH: the paint from the paint container is provided with a driven scraping rack, which presses the paint in the container by means of a basket-like pressure cap located in the container and conveys it in the direction of the outlet opening in accordance with the larbverbraueh.

This known inking device allows a dosage of the color required for consumption, but conditionally the use of a sealing roller and additional scraper devices a complicated container closure, so that no commercially available paint shipping or paint storage containers can be used. Also with this inking device no precautions have been taken to distribute the color evenly in the longitudinal direction of the inking roller. Because the The paint container must be fixed because of the complicated discharge mechanism, it is not possible to use the paint container e.g. to be mounted on a slide that can be moved in the longitudinal direction of the inking roller.

The invention is based on the object of addressing the disadvantages of the known device for inking the inking roller of a printing press to avoid. The inking device according to the invention should, in addition to an exact distribution of the color in the longitudinal direction the inking roller also provides a precise, steplessly adjustable regulation of the amount of ink emerging from the ink container enable.

The inking device should be simple and uncomplicated Structure and have such a function. Furthermore, it should be suitable for the use of a simple, commercially available Parb container.

The solution according to the invention is characterized in that the ink container is arranged displaceably in the direction of the ink roller, and that tightly into the outlet opening of the paint container insertable paint outlet member on the slide is arranged stationary, the color by applying a continuously adjustable external pressure on the opposite the ink outflow member displaceable ink container from this is squeezed.

The inking device according to the invention also enables one precise limitation of the paint application parts also a precise, optionally adjustable regulation of the from the paint container amount of paint escaping. The coloring device is here simple construction and has a simple function ^ a commercially available paint container can be used.

The color outflow member is preferably as an elongated, tubular body formed, which merges at one end into a piston, which tightly into the outlet opening of the paint container can be used and has a passage opening for the paint, and the one at its other end has a discharge nozzle located near the inking roller.

An expedient embodiment., Derc :. invention is characterized in that a pressure-tight housing firmly connected to the slide is on the slide is provided, in which the paint container can be used, the paint container by introducing Compressed air is displaceable into the housing for the purpose of squeezing out paint with respect to the paint outflow member.

In another preferred embodiment of the invention, a feed device is stationary placed on the carriage; this has a feed member designed as a rack and drive members on, the speed of which is optionally adjustable, the rack on the Attacks paint container and this in order to squeeze out paint against the locally fixed paint outflow member shifts.

A modified expedient embodiment of the Invention comprises a resilient material made of a paint container that can be squeezed is formed and is attached in a pressure-tight housing, the paint container by introducing it compressed air into the housing to squeeze out paint.

In the following the invention is explained in more detail with reference to the drawings, namely show:

Figure 1 is a partially schematic and partially elevational view in which parts have crawled away;

Pig. Figure 2 is a sectional view of the inking roller of a Printing press;
