FR2580227A1 - ROTARY WITH PRINTER GROUPS EQUIPPED WITH LATERAL BUILDINGS EACH BY A LOWER PART AND A SUPERIOR PART - Google Patents

Abstract

ROTARY WHOSE PRINTER UNITS ARE EQUIPPED WITH SIDE FRAMES CONSISTING OF A LOWER PART AND AN UPPER PART. THE SIDE FRAMES 8, 9 ALLOW THE ROLLS OF A PRINTING GROUP TO BE MOUNTED LIKE THOSE OF A VARNISHING GROUP. THE INVENTION ALLOWS THE RATIONALIZATION OF SERIAL MANUFACTURING OF SIDE FRAMES, STORAGE AND AVAILABILITY.

Description

The present invention relates to a press whose printing units

  are equipped with side frames each consisting of a

  lower part and an upper part.

  German Patent No. 1,243,210 already discloses a offset web offset with divided sidewalls. This patent describes the arrangement of the printing cylinder and blanket cylinders in a lower autonomous group and the arrangement of each plate cylinder with its inking and wetting in a self-contained upper group. Both groups are

  mounted separately, then the two side walls of the upper groups

  and lower are screwed in a known manner. This invention does not, however, make it possible to arrange different higher groups on a

lower universal group.

  The invention aims to develop side frames for mounting both the rolls of a printing group and those of a varnishing group, to streamline mass production

  side racks, storage and availability.

  According to an essential characteristic of the invention, the lower part comprises fixed bearings for mounting a printing cylinder, a blanket cylinder of a plate cylinder; and the upper insert includes bearings for the plate cylinder and inking rolls. This results in significant time savings when assembling machines

  printing. The rationalization effect has a positive influence

  on the high number of mass-produced side frames.

  According to another characteristic of the invention, rolls of a varnishing unit, a double coating unit or a printing unit used in a blanket washing device are mounted in the side frames. This advantageous characteristic

  makes it possible to transform a varnishing group into a printing group

  mantle or vice versa, without replacement of the lateral elements

an editor.

  Other features and advantages of the invention will be

  better understood using the following detailed description of

  Embodiments and accompanying drawings in which: Figure I shows the last printing unit of a press;

  Figure 2 shows the last group printing with a

  varnishing system; Fig. 3 shows the last printing group with a double glazing unit; FIG. 4 represents the last printing unit made in a varnishing group; FIG. 5 represents the last printing group in the form of a varnishing group;

  FIG. 6 represents a press with a reversing device;

is lying; and

  Figure 7 shows the bearing bore in the lower parts of

  top and bottom of a side frame.

  Fig. 1 shows the last printing unit 1 of a press. The latter printing unit 1 is constituted by an inking mechanism 2, a plate cylinder 3, a blanket cylinder 4, a printing cylinder 5, an output cylinder 6 and an output stack 7. The side housings of the last printing unit 1 are constituted by the lower part 8 and the upper part 9,

  which are assembled in a manner not shown.

  The upper part 9 has the same dimensions as

  those of the previous printing units of the press.

  Figure 2 shows again a last printing group

  1 having a combination printing group / varnishing group.

  It comprises the inking mechanism 2 with the plate cylinder 3. The varnishing unit is constituted by a varnish tray 10, in which the metering roller 11 rotates. The latter is in direct contact with

  the roller 12, which transfers the varnish to the blanket cylinder 4.

  The last printing group 1 of Figure 2 can also function

  group, as shown in Figure 1. In this case,

  the varnishing unit serves as a blanket washing device.

  the inking mechanism 2 is obviously out of order when the last group

  1 of Figure 2 is used in a varnishing unit.

  The lower 8 and upper 9 parts are strictly identical.

  to those described in Figure 1.

  Fig. 3 again shows a last printing unit equipped with a double glazing unit. The first coating unit is again constituted by the lacquer tray 10, the metering roller 11 and the roller 12. The second coating unit 13, arranged above the previous one, allows

  example to perform reserve varnishing. The lower part

  8 is not changed in this case too; the upper part

  The top 14 of this double glazing unit is smaller than the upper part 9 described in FIGS. 1 and 2. A smaller upper portion 14 suffices as a result of the absence of an inking mechanism. FIG. 4 shows the last printing unit 1 with the varnishing unit constituted by the lacquer tray 10, the

  metering roller 11, the roller 12 and the cylinder of white

  classic chet 4. The lower part 8 is simply covered

by a plate 20 in this case.

  FIG. 5 also shows the varnishing group con-

  The lacquer pan 10, the metering roller 11 and the metering roller 12 are arranged in a second position. A second coating roller 15 is provided in place of the blanket cylinder. As in the case of Figure 4,

  the lower part 8 is covered by a plate 20.

  Fig. 6 shows a press with the printing units

  1 to n and the side frames with lower and upper parts.

  This press comprises, as in FIG. 1, a last printing group n. However, it is equipped in this case with a device

turnaround 19.

  The various combinations of the lower part 8 and the upper parts 9, 14; 20, described in Figures 1 to 5,

  the same is possible for a rotary press with

19.

  FIG. 7 represents the lower part 8 with the upper part 9 and, in phantom, a second upper part 14. A bearing bore 16 lies half-way in

  the lower 8 and upper 9 or 14.

  The possibilities of combinations of the lower and upper parts are not limited to the examples shown. Other manufacturing variants of the side frames are conceivable and feasible. Of course, various modifications may be made by those skilled in the art to the principle and to the devices which have just been described solely by way of nonlimiting examples, without

depart from the scope of the invention.
