2. The device according to claim 1, characterized in that between the ink tank 1 and the metering roller 2 there is a large number of 2 segmented gate valves 4 lying on the metering roller, one of the walls of the ink tank 23 with a flexible knife 8 fixed on its lower end adjacent to the dosing roller 2. 3. The device according to paragraphs. 1 and 2, characterized in that each gate 4 interacts with at least one dosing chamber 12 located in the metering roller 2, and a piston-shaped pin 14 with a drive, preferably cam-cam, located in each metering chamber 12. 4. Device on PP. 1-3, characterized in that each dye zone 13 corresponds to several dosing chambers 12 having different diameters, and as many gates 4. 5. The device according to claim 1, characterized in that in the dosing roller 2, preferably two opposite rows of dosing chambers 12, 27 are located. The invention relates to a dosing device for an inking apparatus, especially on offset printing machines, which in order to adjust the desired thickness of the ink layer dyes the ink according to a given value of m. In most of the known inking devices, wedge-shaped or knife-based paint tanks are used, in which the thickness adjustment of the ink layer occurs by moving a solid ink knife with respect to the surface of the ductor. The colorful knife is pressed to the dicor with screws of colorful zones. In principle, it is possible to adjust the individual zones in different ways so that a different profile corresponding to the customized edition can be obtained across the entire width of the inking apparatus. However, the result of the mutual influence of the colorful zones as a result of the elasticity of the colorful knife is that the movement of the colorful zone affects one or several adjacent or also remote colorful zones without changing the setting of the colorful zones there. In order to obtain a precisely adjustable inking profile, paint supply devices were found, in which the dosage and removal of paint are controlled by cherc pumps (Swiss Patent No. 392565, class 15 d, 34/04, March 17, 61). With the help of a plurality of pumps dispersed next to each other distributed across the width of the ink, the ink is applied to the roll roller. With relatively high costs, a very accurate dosage of paint supply to individual paint spray nozzles corresponding to the paint zones is achieved. However, the implementation of a short-term change of the edge, including the cleaning of all colorful pumps, pipelines, nozzles and l-, d., Despite all the improvements of these devices, is not solvable, not considering the high cost of an individual drive for each individual zone, as soon as these devices are attached the value of the controllability of the flow rate of each nozzle to establish a variable ink profile. For this reason, pumping, spraying, brushing and centrifugal pumping devices are not widely used. Therefore, the colorful devices with a wedge-shaped or knife-like colorful reservoir were especially improved, their shortcomings were revealed and significantly reduced. This improvement in dosage was achieved, on the one hand, by means of measures for faster reaction. 0 dyeing apparatus with a change in dosage (German application No. 2553177, cl. B 41 F 31/00, 08.19.76). On the other hand, solid colorful knives were independently equipped with each other. 5 from each other acting pieces of a colorful knife, for example, with the help of partial slits (Swiss Patent No. 561119, class B 41 F 31/04, 21.12.73) Knives for paint dosing are also known, consisting of gates of separate parts (patent US No. 1275348, CL 101-363, August 13, 188, and US Patent No. 1574474, CL 101-365, 02.23.26. These gates (US Patent No. 3978788, CL 101-363, 07.09.76) are placed Near a friend across the entire width of the ink tank in such a way that, in general, they form a solid ink knife, but can be moved separately, i.e., in the ink zones without any random effect on each other. To change its position with respect to the ductor, each gate is connected to an electric motor, which, through its corresponding gear and eccentric, acts on the gate. The disadvantage of this colorful knife design is that all inaccuracies in adjusting the gates immediately and significantly affect the prescribed dosage of paint in the form of a deviation. Even with a significant reduction in the number of revolutions of the engine relative to the movement of the eccentric, you can only approximately adjust the planned or calculated paintball, spruce. In addition to this, fixing an extremely accurate installation of the colorful slit requires relatively high costs of adjustment, registration of its size and search, and this is only up to a certain limit of accuracy. It is known the use of colorful tanks with a funnel-shaped cross section instead of wedge-shaped colorful tanks. With this known cross sectional shape of the ink reservoir, at least one of both longitudinal walls is designed as a solid dosing knife (U.S. Pat. No. 3,730089, cl. 101-363, Ol.05.73). The purpose of the invention is to create a dosing device for an inking apparatus, whose inking profile can be adjusted according to predetermined values. The invention is based on the task of creating a dosing device for the dyeing apparatus, refusing continuous and sensitive adjustment of the height of the inking gap between the inking knife and the ductor roller to the inking zone, where accurate, extremely predetermined dosing of dye in the range is made across the entire width of the inking tank. a wide range of adjustments, the executive bodies of which can be installed within precise end points to improve remote controllability provisions. Mutual zonal influence should be eliminated, and each of the specified colorful profiles should be reproducible. Also, when using the remote control, manual correction must be provided at any time. To this end, a dosing roller is provided between the inking tank and the first roller of the inking apparatus, equipped with at least one row of metering chambers, and the inking tank can be completely or partially closed on the side of the metering roller. At the same time, the paint reservoir on the side of the metering roller must be fully or partially closed with the help of a large number of segmented gate valves adjacent to the metering roller. Moreover, one of the walls of the colorful reservoir with a flexible knife fixed on its lower end is adjacent to the dosing roller. Each gate interacts with at least one of the dosing chambers located in the dosing roller, and a piston-shaped pin with a cam or similar control is installed in each of the dosing chambers. Each dye zone corresponds to several dosing chambers with different diameters and as many with different width gates. Preferably, two dispensing chambers arranged opposite each other can also be placed in the metering roller. The advantage of the invention is that the dosage of paint is made by means of gates or pushers moving only in clear end positions. Since several slides of different widths or several dosing chambers having different diameters can be applied to each colorful zone, extremely precise dosing can be achieved. For example, in the colorful zone with three different dosing chambers, only the smallest one can be used, while both of the other dosing chambers are closed with the corresponding valves and pushers. You can also use only the medium or only the largest dosing chamber and also all the executable combinations up to the use of all the dosing chambers of the colorful zone. Further dosing possibilities result from the possibility of rotating the dosing roller at different speeds. In addition, it is also directly possible to set the dosing roller in motion, for example, by means of a Maltese cross mechanism so that the transfer of paint to the dosing chambers is carried out with a brief stopping of the dosing BajiHKa. The drawings show two examples of the drying of the invention. FIG. 1 shows a dosing device for an inking apparatus with a colorful reservoir closed on the side of the dosing roller, a partial section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - colorful reservoir, open from the dosing roller; in fig. 4 shows a section BB in FIG. one; in fig. 5 - drive located in the dosing chambers of piston-shaped pins; in fig. 6 is a sectional view BB in FIG. five; in fig. 7- dosing device, but with two rows of dosing chambers located opposite each other. The ink reservoir 1 is located above the preferably continuously moving dosing roller 2, which is connected to the other conventional rolls and the like rollers of the ink apparatus through the roller of the ink apparatus 3. Between the colorful reservoir 1 and the dosing roller 2, across the entire width of the inking apparatus, close to each other are the tongs 4, which (FIG. 4) may have different widths. Each gate 4 corresponds to the installation device. This may be a magnet b acting through a double lever 5 or also an electronically controlled bar for stops or the like. The condition is only that each pin 4 moves either up to the stop 7 to one or its front end to another position before the flexible knife 8. The colorful reservoir is supported on one side by the flexible knife 8 on the dosing roller 2, while on the other side it adjoins the shelf 9 to the sliders 4. For the straightline guiding of the tweezers 4 in the shelf 9 (Fig. 4), guide grooves 10 can be provided in which the guide ribs 11 of the tweezers 4 slide. The dosing roller 2 is equipped with a large number of dosing chambers 12 having different dia tr. Each of the colorful zones 13 (see Fig. 2) is equipped with several different dosing chambers 12 and also preferably with different width gates 4. Each of the dosing chambers 12 is equipped with a pin 14 mounted on a common marzan 15. This marzan 15 is issued on one side of the colorful of the apparatus through the wall of the machine 16 (Fig. 6) and on this side, through the axes 17, supports two contact rollers 18 rolling inside the cam 19 fixed on the wall of the machine 16 and thus controlling the movement process of the marzan 15 and thus also the pins 14. The dosage of paint is as follows. From the ink tank 1, the ink enters all the dosing chambers 12, the gates 4 of which occupy the position shown in FIG. 3 position. Changing the position of the gates 4 is possible in principle manually or also according to a given program, and both possibilities can also be provided on the same object. Since several dosing chambers 12 accept different volumes for one colorful zone 13, depending on the number of selected diameters of the dosing chambers used, controllability can be achieved in permissible small steps from zero to the required maximum. The cam 19 is preferably designed in such a way that, under its influence, the pins 14 in the area of the gates 4 are drawn inward, so that all the dosing chambers 12 not closed by the gates 4 receive paint. Upon further rotation of the metering roller 2 by means of the flexible knife 8, it is achieved that the paint does not catch around the circumference of the metering roller 2, with the exception of the metering chambers 12. When reaching the point of contact on the roller side of the inking unit 3, the pins 14 are moved by the cam 19 to the outside in the manner described, so that the paint is transferred to the roller of the inking unit 3. Shortly after the point of contact of the metering roller 2 to the roller of the inking unit 3, a doctor blade can be provided final paint removal. It turned out to be expedient to move the pins 14 in such a way that in the dosing chambers 12, after their contact with the roller of the dyeing apparatus 3, the residual amount of paint remains. The invented design of the inking device also makes it possible to provide in the dosing roller still, for example, a second row of dosing chambers 12 with pins 14 corresponding to the pins, as shown in FIG. 7. Recognized as an invention according to the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
