    The invention relates to equipment for a sheet rotary printing press, in particular, devices for adjusting the transverse and circumferential wiring to a roll of a rotary sheet printing press.
    A device for transverse and circumferential registration to a plate cylinder of a sheet-fed rotary press is known, comprising a first flywheel, via a first worm wheel, connected to a first pivot arm, with a positive lock connected to a first movable sleeve, which is rigidly fixed on one end of a journal mounted on to the shaft of the plate cylinder, the second flywheel, through the second worm wheel connected to the second pivot arm, with a positive lock connected to the second
    a movable sleeve that is axially movable mounted on the end of said trunnion and fixedly connected with fitted oblique teeth mounted axially movable on the axle end of a toothed crown which, with ensuring joint rotation through cylindrical bolts, is connected to the toothed wheel mounted to a prismatic key at the end of the axle.
    In the known device, the transverse register is carried out by axial movement of the plate cylinder, regardless of the circumferential register, which is carried out by axial movement of the toothed rim provided with oblique teeth, which engages with
    the toothed wheel of the subsequent cylinder.

    A disadvantage of the known device is that only coarse regulation of the circumferential register is possible, since, due to the design, the gap between the crown gear movable on the trunnion and the fine adjustment shaft cannot be reached. In addition, using the means described, fine adjustment of the cross register is not possible.
    The purpose of the invention is to provide fine adjustment of the register.
    The goal is achieved by the fact that in a device for adjusting a transverse and circumferential register to a roll of a sheet-fed rotary printing machine, containing at least one first drive connected to means containing at least one rotary lever for adjusting the register circle, and a second drive connected to means for the axial movement of the roll, means for adjusting the circumferential register is made as means for setting the roll made as the drive cylinder ozhnostyu its eccentric rotation.
    The device can be equipped with an automatic control tool, by means of which, during the operation of the machine, the position of each sheet is checked separately and, when it deviates from a predetermined position, the corresponding transverse and circumscribed register is automatically carried out.
    Due to the fact that the invention provides fine adjustment of the register, it can be applied without any restrictions to machines for the production of securities where accuracy is required.
    FIG. 1 is a diagram showing the position of the register cylinder provided with the proposed device as a whole, with a roll of a sheet-fed rotary printing press, side view; figure 2 - register cylinder, provided with the proposed device, the section; in FIG. 3, means for setting the cushion cylinder with the possibility of eccentric rotation; Fig. 4 is a block diagram of an automatic control device of the proposed device.
    In a sheet rotary printing press, in aggregate, 1 rollers between the two transfer cylinders 2 and 3 are installed the register cylinder 4, equipped with the proposed device for adjusting the transverse and circumferential register of the sheet 5. Before (along the paper) the first transfer cylinder 2 is installed the last one is a spare cylinder 7. An offset cylinder 8 is installed behind the second transfer cylinder 3 (FIG. 1). In addition to the register, all other cylinders (2, 3, 6, 7 and 8) are installed directly in the side beds of 9 and 10 of the sheet-fed rotary printing machine.
    From figure 2 it is seen that the register cylinder 4 contains the shaft 11, the left end 12
    0 fixedly connected with the left lever 13, and the right end 14 - with the right lever 15.
    The levers 13 and 15 are rotatably mounted on bolts 16 and 17, which are rigidly fitted in
    5 lateral beds 9 and 10, and they are separated from the lateral beds 9 and 10 by means of spacer rings 18 and 19. The levers 13 and 15 have a common axis of rotation 20 that is located a distance from the axis 21 of rotation coaxially
    0 with the shaft 11 of the shaft 22 of the cylinder 4. The shaft 22 with the help of needle bearings 23 is mounted on the shaft 11 for rotation and axial movement. The left lever 13 through the bolt 24 is pivotally connected
    5 with a control rod 25, and the right lever 15 through a bolt 26 is pivotally connected to the control rod 27. In a preferred embodiment, the control rods 25 and 27 are mounted
    0 parallel to each other and through the intermediate elements 28 and 29 are connected to a rotary mounted synchronous shaft 32 fixed in the lateral beds 9 and 10 fixed to the lateral beds 9 and 10. The intermediate elements 28 and 29 are rigidly connected to the synchronizing shaft 22 and the intermediate element 28 is hinged connected to the first end 33 of the control rod 25, while the intermediate element 29
    0 is pivotally connected to the first end 34 of the control rod 27.
    Bolts 35 and 36 serve as a hinge for connecting intermediate elements 28 and 29 with control rods 25 and 27,
    5 through the return spring 37 and 38 connected with rigidly mounted in the beds 9 and 10 of the pins 39 and 40 (figure 2). At the second end 41, the control rod 27 is provided with a rotatably mounted
    0 by the first roller 42 running in an axially oriented contour 43 mounted with the possibility of adjusting the first distribution cam 44. The first distribution cam 44
    5 is rigidly connected to the first end 45 of the control shaft 46. The control shaft 46 is rotatably mounted in a support 47 fixed in the side frame 10. The second end 48 of the control shaft 46 is connected to the driven shaft 49 of the first drive. The position of the driven shaft 49 and the control shaft 46, i.e. the angle at which they are installed is controlled by the first pulse sensor 51 connected to the driven shaft 49 (FIG. 3).
    It is also seen from FIG. 2 that the lower end 52 of the lever 15 is rigidly connected to the second distribution cam 53 having a radially oriented contour 54, and the roller 55 driving the opening movement of the grippers 56 rolls along the distribution cam 53. The roller 55 is well known rotatably mounted on a lever 57 rigidly connected to the shaft 58 on which the claws 56 are mounted. The shaft 58 is rotatably mounted in the supporting structure 59 which is fixedly mounted on the shaft 22. At the right end 60 of the shaft 22 is fixed These gear 61 engages inbound and driven from the gear wheel 62 of the transfer cylinder 2, which is in front of the cylinder 4 privodochnym.
    On the left side 63 of the supporting structure 59, a support 64 is fastened externally to the second roller 65 mounted for rotation. The second roller 65 rolls along the annular face 66 of the first distribution disk 67 installed vertically with the possibility of rotation in the direction facing the supporting structure 59, and to the side, turned away from her. The first distribution disk 67 in the upper part 68 is rotatably mounted around the axle 69 fixed in the frame, and in the lower part 70 it is equipped with the third roller 71 rotatably mounted. The third roller 71 rolls around the axially oriented contour 72 of the second distribution disk 73. The second distribution the disk 73 is mounted on the end 74 rotatably mounted in the side frame 9 of the control shaft 75. The control shaft 75 is driven from the side frame 9 installed and made in the form servomotor 76 second drive. In order to return after axial movement, several compression springs 77 are provided, horizontally resting against the lever 15 and acting on the axial bearing 78, also axially resting against the shaft 22,
    According to a particularly preferred embodiment, two servomotors 50 and 76 are connected via electric wires 79 and 80 to processor 81, from which they
    receive data on the regulation of the register (figure 4). The processor 81 is connected via an electrical wire 82 to a reading device 83, which is located at a distance from the transfer cylinder 2 and is used to determine the position of the sheet 5 turned over from the cylinder 6. The signal encoding the position of sheet 5 is transmitted to the processor 81. where it is compared with the corresponding setpoint values on axial position and position on a circle. At the same time, a signal from the first pulse sensor 51, indicating the position of the first distribution cam 44, enters the processor 81 via the electrical wire 84, and a signal from the second pulse sensor 86, indicating the position of the second distribution disk 73, flows through the electrical wire 85. Based on this data, the processor 81 calculates the wiring that transmits servo motors 50 and 76 as actuating pulses.
    The adjustment of the counting register is carried out as follows.
    Depending on the position of the next sheet 5 on the transfer cylinder 2, the servomotor 50 rotates the control shaft 46 to the right or left, as a result of which the first distribution cam 44 rotates respectively. Through the contour 43 of the first distribution cam 44 and the first roller 42, the control rod 27 moves towards the return shaft springs 37 and 38. Consequently, the lever 15 pivotally connected to the control rod 27 and the lever 15 rotates around the axis 20 of rotation of the bolt 17. Connected to the lever 15 through intermediate elements 28 and 29 and the synchronizing shaft 32; the lever 13 performs a corresponding pivotal movement around the bolt 16. The axis 21 of rotation of the shaft 11 moves around the axis 20 of rotation of the bolts 16 and 17 along a circular path. Due to the fact that the rotation angle is small, this movement can be viewed as a linear movement of the shaft 11. Due to the coupling of the gear wheel 61 to the wheel 62, the latter and, therefore, the register cylinder 4 rotates around the coupling point A of the gear wheels 61 and 62, at the same time, it is also the transfer point of the sheet 5 from the transfer cylinder 2 to the register cylinder 4. This point is constant and does not move. The transmission cylinder 3 is not in gearing with the actuating cylinder 4 and therefore does not make a turning movement of the latter.
    as a result, there occurs a relative displacement of the point B of the transfer of the sheet 5 between the grips 56 of the reduced cylinder 4 and the grips of the transfer cylinder 3. Point B is movable. The grippers are installed and configured to support sheet 5 in accordance with the register in the required area (approximately 3 mm). Moving the control rod 27, for example, in the direction of the arrow to the left, entails turning the register cylinder 4 clockwise and simultaneously moving point B to the left, i.e. in the direction of sheet feed forward.
    When adjusting the cross register, the servomotor turns the control shaft 75 to the right or left (depending on the position of the sheet 5 on the transmission cylinder 2) and the second distribution disk 73 rotates accordingly. Through its contour 72 and the third roller .71 the first distribution disk 67 rotates around the trunnion 69, so that the second roller 65, rolling around the end side 66 of the first distribution disk 67, axially moves the register cylinder 4 in the direction of the force of the compression springs 77 or in opposite wrong direction.
    It is possible to carry out the device without a synchronizing shaft 32, while the levers 13 and 15 are rotated separately. In this case, the lever 13 is connected to the corresponding elements 51, 46, 44, and 42. This allows the asynchronous control of the levers 13 and 15 to be carried out at an angle to adjust the driving cylinder 4
