The invention relates to the printing industry, to devices for offset printing 4
The purpose of the invention is to increase the convenience of operation.
Fig. 1 shows a schematic diagram of the device, a side view, and Fig. 2 - the same, longitudinal-vertical section; in FIG. 3 - the same, vertical: flax-cross section j in FIG. 4 is a schematic diagram of the lower part of the cassette and its associated elements mounted on the frame; in fig. 5 - the lower part of the front frame of the bed and the front wall of the cassette, transverse-vertical section; in fig. .6 - cassette replacement scheme; in fig. 7 is a diagram of the installation of two cassettes on the carriage in diametrically opposite positions.
A device for offset printing on panels of various formats, containing mounted on a frame with front 1 and rear 2 longitudinal racks at least one knurled cylinder 3, interacting with it colorful 4 and moistening 5 devices in contact with knurled 3 mold cylinder 6, interacting with it offset 7 and printing cylinder 3 mounted on a movable bracket 9 for clamping to offset cylinder 7 of - The cloth 10 is located between offset 7 and printing 8 cylinders Form 6 and offset 7 cylinders are mounted the possibility of rotation between the front 11 and rear 12 vertical longitudinal walls interconnected by crossbars 13 and forming with them moving in the direction perpendicular to the movement of the cloth, the cassette 14 supported by rollers 15 and 16 mounted in the upper part of the cassette 14 with horizontal longitudinal axes on two transverse rails 17 and 18 located in the upper part of the device between the front 1 and rear 2 longitudinal stands of the bed and speakers in front of the front stand 1 of the bed. At the rear of the bed 2 of the bed, the drive gear 19 is rotatably mounted, which is connected to the plate 6 and offset 7 cylinders using gears 20 and 21,
The device has a carriage 22 with a horizontal-rotary base plate 23 for the cassette 14 and two brackets 24 rotatably mounted on the outer side of the front leg 1 of the bed.
The front wall 11 of the cassette 14 is equipped with additional rollers 25 with horizontal longitudinal axes mounted in its lower part,
jQ interacting with the corresponding brackets 24, at the beginning and the end of the output of the cassette 14, and bearing in the form of the console 26 when the cassette 14 is removed from the device, the latter has
5, an additional removable movable support plate 27 placed on the frame under the printing cylinder 8 for interacting with additional rollers 25, which carries the locking lever 28,
0 and in the cantilever 26, a notch 29 is made to accommodate the locking lever 28. The first of the transverse rails 17 is a cylindrical rod with a horizontal flat 30 for
5 interacting with the respective rollers 15 of the cassette 14, in the walls 11 and 12 of which radius grooves 31 are made to accommodate the rail 17. The second rail 18 has a groove
0 32 triangular profile to interact with the rollers 16 of the cassette 14.
The cassette 14 is equipped with a shock-absorbing jack 33 and an adjustable stop 34.
. The device works as follows.
Suppose that the device prints a printing cylinder 6 and a offset cylinder 7 large
format and that it is necessary to replace these cylinders with the forme cylinder 35 and the offset cylinder 36 of a smaller format in order to switch to a smaller print format. With a large print format, the printing cylinder 8 is in position A (FIG. 2), the shock-absorbing jacks 33 are in operation in such a way that each of them, through its rod 37, exerts a force F directed obliquely
0 up. Thanks to the effort F, each of. the vertical walls 11 th 12 are pressed against the right rail 17 and the stops 34 having the shape of an angle. In this position, the cylinder 35 is pressed against the on-off 5 cylinders 3 mounted on
bed frame. Adjustable stops 34 allow you to adjust the force of contact between the cylinder 6 and the rolling Qi5
lindra 3 right and central, i.e. the degree of compression of the elastic surface layer of these rolling cylinders. Due to the presence of force F, the upper rollers 15 and 16 are raised relative to the upper guide rails 17 and 18.
Suppose that the replacement of the block is accomplished by means of a lifting mechanism, such as a winch mounted on a carriage moving along an upper rail. In this case, the cassette 14 is removed in an appropriate manner (Fig. 6).
Before you begin to remove the cassette 14 with the plate cylinder and offset cylinder 7, turn off the power of the jack 38 so that the print cylinder 8 takes up its lowest position below the bottom ones. The edges of the walls 11 and 12. Then overlap the power of the shock-absorbing jacks 33, after which the cassette 14 under the action of its own weight is lowered onto two guide rails 17 and 18. In the first phase, the cassette 14 rotates around the cylindrical part of the right guide rail 17 until roller 16 enters groove 32. Then, some sliding to the left occurs until roller 16 does not abut against bottom of groove 32, and right roller 15 does not abut against upper rail 30 of upper right rail 17. After that, fold Q0a front crowns matte 24 from the vertical to the horizontal position (solid line, fig. 5), the locking lever 28 is still in the vertical position (fig 4) in which its lower end is in the notch 29. Starting from this point, the front wall 11 and, consequently, the entire cassette 14 is connected with the console 26 and with the additional plate 27. Thereafter, the cassette 14 is pulled forward, withdrawing it from the bed of the printing device. In so doing, the plate 27 is extended forward and occupies the corresponding position (Fig. 6, dash-dotted line);
At the beginning of the movement, the four upper rollers 15 and 16 roll along the two upper guide rails 17 and 18, and then only the rollers mounted on the rear machine 12, rest on these rails, since the corresponding rollers mounted on

front wall 11, go off these rails. Starting from this moment, the weight of the block partially falls on the front protruding end of the plate 27. When the cassette 14 is fully extended, the lower rollers 25 mounted on the back wall 12 are transferred from the printing device (Fig. 6, dash-dotted line to the line) to the brackets 24 and hold the rear end of the cassette 14, the front end of which is still held by the console 26 fixed to the front end of the movable plate 27. When i the cassette 14 is fully extended from the printing device, it can easily be lifted using lifting fur nism, for example a winch, and replaced by another cassette 11 with the cylinder 35 and blanket cylinder 36 corresponding to the smaller format printing.
The operation of inserting the new cassette 14 into the printing apparatus is carried out in reverse order. Push the movable assembly inside the printing device until the movable plate 27 and the cassette 14 are completely inside. The additional cushioning jack 39, mounted on the plate 27, abuts against the Stop 40, mounted on the bottom of the printing device, with In order to avoid a sharp blow when inserting the cassette 14. After that, power is supplied to the shock absorbing jacks 33 to press the new cylinder 35 against the rolling cylinders 3. During the first phase, the walls 11 and 12 move in the direction of the upper rail 17 As long as the recess 31 of each of these walls does not contact with the cylindrical surface of the rail. Then, under the action of force F, the entire cassette 14 is rotated around the axis of the right upper rail 17, as a result of which the new cylinder 35 is pressed against the cylinders 3 right and central. The third cylinder 3, located to the left of the preceding ones, under the action of a jack (not shown) rests on the pre-adjusted stop of the cassette 14. The adjustable stops 34, which remain in the same position, ensure the same pressing force as before.

In the upper part of the carriage 22 (Fig. 7 is mounted a horizontal plate 23 turning on a vertical axis 42. On this plate there can be radially arranged cassettes 14, indicated by a dash-dotted line. In this case, the movable retaining plate 27 is not used. To do this, fold the lever 24 from vertical to horizontal position. Horizontal communication is established between the brackets 24 extending horizontally and the turning plate.
23 using hooks 42 pivotally mounted on the edge of the plate 23 on axles 43 and capable of hooking fingers 44 provided on levers 24. In this case, when the cassette 14 can be removed from the device, the lower front rollers 25 roll
on the brackets 24 and then abut against the upper surface of the rotating plate 23 o The rear lower rollers also pass on the brackets
24 and roll onto plate 23. Once previously used from cassette 14, it is radially mounted onto plate 23 of its

rotates 180 and inserts a new cassette 14, sets it against the holes in the racks 1 and 2, then inserts a new cassette between the racks, similarly to that described, then install the lever 28 from the horizontal to the vertical position (fig 4) where the lower end of the wedge goes into the recess 29, instead of the turning plate 23 mounted at the top of the carriage 22 ,. It is also possible to provide several compartments for placing the cassettes on the carriage located at some distance from each other in the longitudinal direction. In this case, after placing the previously used cassette in the corresponding compartment, it is enough to move the carriage longitudinally in front of the new cassette, made in racks 1 and 2,
