    The invention relates to the printing industry, in particular to devices for rolling out a liquid medium, such as printing ink or a moistening liquid used in offset presses.
    . The aim of the invention is to improve the quality of the medium roll.
    On fi. 1 shows a diagram of a printing section in which devices are used for rolling paint and a stage of moisturizing liquid; in fig. a device for rolling liquid media; a first embodiment of rolling rollers; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 3; in fig. 5 is a device for rolling out a liquid medium, having intermediate rollers; in fig. 6 is a view of st. B in FIG. I; in fig. 7 shows a second embodiment of the roll rollers; in fig. 8 - making a roll roller in the form of a straight circular cone; On fig7.9, the third embodiment of the rolls; in fig. 10 is a diagram of an inking apparatus with a device for liquid rakaat according to the third variant.




    FIG. Figure 1 shows a rotary printing section with the proposed paint inks for a moistening liquid, in which the inking unit paints the rubber with a rubber-wrapped knurling roller 1, which in turn transmits the paint to the surface of the stereotype 2 pulled over the plate cylinder 3. From the stereotype 2, the paint is transmitted On the rubber sheet 4 of the offset cylinder 5, the roll roller 1, the forma 3 and the offset 5 cylinders have the same diameter and rotate at the same angular velocity. The moistening fluid 6 is supplied to the surface of the knurling roller i by means of a duct cylinder 8, intermediate rollers 9-13 and transfer rollers 14 and 15. The doctor cylinder 8, intermediate rollers 9-13 and the transfer rollers 14 and 15 have a significantly smaller diameter than Roller 1, with rollers 12, 14 and 15 designed for paint rolling.

    The printing section has devices for the dissolution of a liquid medium, in particular a wetting unit 6 and devices for the expansion of ink.
    In the first embodiment, the device comprises a drive cylinder 16 with a hard surface and axially symmetric roll rollers in contact with it, which form a pair of rollers 17 and 18 arranged along the axis of the drive cylinder and the axes 19 and 20 of rotation of the roll rollers 17 and 18 are placed at an acute angle to the axis 21 rotation of the drive cylinder 1.6 and in the same plane with it, and the axes of rotation 19 and 20 of each two adjacent rollers 17 and 18 intersect.
    Each roll roller 17 or 18 may be in the form of a straight circular cone (Fig. 8), a straight truncated cone shape (Fig. 4), or have a semi-circular surface in the axis direction (Fig. 7). In this case, the roll roller must be ATb filled with a very elastic material, and its axis may be located to the axis of the cylinder 16 at any acute angle. It is preferable that all the roll rollers are made with a solution angle of the cone 90, and their axes
    The 19 and 20 rotations were placed at an angle of 45 to the axis of rotation 21 of the drive cylinder 16.
    For mounting roll rollers
    5 17 and 18 used carrier tire 22 with brackets 23, on each of which the corresponding roller 17 and 18 is mounted by means of a bearing 24. Roller rollers 17 and 18 of each
    0, the pairs of rollers are in contact with each other directly (Fig. 2), or through intermediate rollers 25 (Fig. 5), which are mounted on the same carrier tire 22 as the roll rollers 17
    5 and 18, and may have a cylindrical
    form.
    A device for rolling out a liquid medium (FIG. 7) contains a driving cylinder 16, with which two are in contact
    P
    rows of roll rollers 17 and 18, with the rollers of one row being offset in the direction of the axis of the cylinder 16 relative to the rollers of the second row.
    The device according to the third variant Kfyg. 9), consists of a drive cylinder 26 with a hard surface, for example, made of ceramic or copper, in contact with it axisymmetric
    rollers 27, an additional drive cylinder 28 having a surface similar to that of cylinder 26, and additional rollers 29 in contact with the cylinder 28.
    Each main roller 27 is in contact with a corresponding additional roller 29, the axis of rotation 30 of all rollers 27 and 29 are parallel to each other and placed at an acute angle to the axis 31 of rotation of cylinders 26 and 28 and in the same plane. Rollers 27 and 29 (Fig. 9) have the shape of a straight truncated cone.
    For a paint roll, several devices of the same type for rolling liquid media can be used, drive cylinders 16, 32 and 33 (Fig. 1) or 26,34 and 35 (Fig. 10), which are successively arranged around the circumference of the knurling roller I between zones of its contact with the plate cylinder 3 and the transfer roller 15, and these devices (Fig. 1) can be combined into a closed system of cylinders and roll rollers.
    As already mentioned, each drive cylinder 16 or 26 may interact with two rows of roll rollers 17, 18 or 27.
    In an embodiment of a device for rolling out a liquid medium (Fig. 10), additional driving cylinders 28
    can interact with each other through intermediate rollers 36. I When this device is in operation, each pair of rollers 17 and 18 is in contact with each other and with the surface of the driving cylinder 16. Each of these contact points is a zone of paint splitting, in which the ink is split and transported in accordance with known laws: Thanks to the pairwise arrangement of the rollers 17 N, 8, the so-called | the ink bridge, as a result of which the ink flow from the surface of the cylinder 16 with a higher level of ink is transferred to those parts of the surface of the cylinder 16 that have a lower level.
    The described bridge arrangement of pairs of rollers 17 and 18 allows printing ink to be transported from one place on the surface of cylinder 6 to another place of this suspension, without resorting to the distribution movement of cylinder 16.
    This is also true for the embodiment of the device shown in Fig. 9,10.
    The proposed device for rolling out a liquid medium can be used not only for rolling paint, but also for a moisturizing fluid, and in all cases it provides a high quality of the roll.
