    专利说明:

    The invention relates to the printing industry, in particular to printing equipment. A device for moving a press cylinder in a rotary deep printing machine is known, which contains double-acting power cylinders, the rods of which are connected to the trunnion supports of the press cylinder, a control system and supplying the working medium to the power cylinders, a device for synchronizing the movement of the trunnion supports of the press cylinder, including located in the bearing supports parallel to the axis of the press cylinder, a synchronizing shaft connected to the axle supports and associated with the fixed ones; in relation to the body of the machine by toothed racks using gears W In a known device, moving the press cylinder away from the onset is terminated when the switch valve blocks the flow of the working medium or when the switch valve is in balance between the weight of the press cylinder, its support and the piston of the power cylinders In this case, however, it turns out that the switching valve is not able to hold the pressing cylinder at the end of the movement to shut off in a strictly defined manner. because it is loaded with full pressure, and with pressure fluctuations, as well as other disturbing influences, this can lead to a slight uncontrolled flow of the working medium through the switching valve, so that the press cylinder is not in the off position of the pressure rest, and oscillates in both directions to the extent that the switch valve alternately releases or blocks the flow of the working medium. Because of this, the onslaught of perfection can be broken. The aim of the invention is to prevent uncontrolled movements of the press cylinder due to pressure fluctuations in the working medium at the on-off position. This goal is achieved by the fact that in a device for moving a press cylinder in rotary intaglio printing machines, containing double-acting power cylinders, the rods of which are associated with trunnion ones. press cylinder supports, a control system and supply of working medium to power cylinders, a device for synchronizing the movement of trunnion supports of a press cylinder, having a synchronizing shaft parallel to the axis of the press cylinder located in bearing bearings parallel to axle supports and connected to stationary wheels of the machine casing by gears, a device for synchronizing the movement of trunnion supports has at least one friction disc brake with one or no Kolk pressure springs, the two coupling halves KOTOpioro mounted on the timing shaft and the respective bearing trunnion, and a friction brake control means. This goal is also achieved by the fact that the friction brake control means contains a working capacity connected to the Tudycha control system to the power cylinders, filled in the friction brake housing, placed in it and in contact with the pressure spring a piston, switching valve connected to the working capacity brakes; travel valve for blocking the supply of working medium to the piston; and choke for switching on the travel valve with delay. Fig. 1 shows a basic cinematic diagram of an intaglio printing press, the position of the disconnected onset; Fig.2 is the same, the on position of the onset; on fig.Z - trunnion support unit and synchronizing shaft, top view, partially cut; , 4-7 - control system and supply of working medium to the power cylinders and means of controlling the friction brake in various operating modes. In the intaglio printing apparatus (Figures 1 and 2), the press cylinder 1 is placed between cylinder 2 and the plate cylinder 3. The press cylinder 1 and cylinder 2 are mounted with their trunnions in the trunnion supports 4 and 5, which are located on the printing press 6 of the radial displacement relative to the plate cylinder 3. The press cylinder 1 is movably mounted relative to cylinder 2 and, due to cylinder 3, is pressed against cylinder 2 as it moves in the direction of its inclusion. Parallel to the machine, power cylinders are fixed to the cylinder 2. Acts 7 and 8, which by their stems are connected with corresponding trunnion supports 4 and 5. Bearing supports 9 and 10 are rigidly connected with trunnion supports 4 and 5 with bearings 11, in which a synchronizing shaft 12 is mounted, carrying gears 13 at its ends which are in engagement with stationary relative to the machine core toothed racks 14. Synchronizing shaft 12 with gears 13 and rails 14 form (a device for synchronizing the movement of trunnion supports 4 and On the synchronizing shaft by bearings 15 a roller 16 is mounted for nap The paper web 17. The gears 13 are engaged with the rails 14 with a small clearance, which allows the cylinders 1 and 2 to be positioned slightly obliquely with respect to the plate cylinder 3, without the interference of the synchronizing shaft 12. The device for moving the press cylinder 1 also contains a control system and supply the working fluid to the power cylinders 7 and 8, and a device for synchronizing the movement of trunnion supports 4 and 5, in addition to these parts, also has at least one disc friction brake 18 and means its control. The friction brake 18 includes a coupling half 19, rigidly fixed on the bearing support 9 (10) and a coupling half 20 fixed to the synchronizing shaft 12. The brake control 18 includes a working capacitance 21 connected by the supply system of the working medium to the power cylinders 7 and 8, A torus 18 molded into the case, placed therein and contacting with at least one pressure spring 22 a piston 23, acting on the brake discs 24 of the brake 18. Through the communication 25 to the piston 23, the working environment can be supplied that the piston 23 will be at the same time from the brake discs 2. Thus, in the absence of the influence of the working medium on the piston 23, the discs 24 are pressed against each other, so that the torque can be transmitted from the synchronizing shaft 12 to the bearings 9 and 10, resulting in a rotational. the movement of the shaft .12 and the lifting movement of the trunnion support 4 are braked. When the piston 23b of the disks 24 is retracted, the movement of the pressing cylinder 1 and cylinder 2 is released. A second friction brake 18 can be placed at the right end of the shaft 12 (not shown) if this arises due to the weight of the cylinders 1 and 2. Elements of the device for moving the pressing cylinder 1 can operate in different modes (Fig. .4-7). From the pressure source 26, the pressure through the valve 27, the communication 28 and the valves 29 and 30 of the fine adjustment, as well as through the communications 31 and 32 is supplied to the cylinders 7 and 8, so that the pressing cylinder 1 and cylinder 2 are moved to the Onslaught position. At the same time, the discs 24 of the brake 18 by means of the communication 33 and the switching valve 34, as well as the communications 35 are released from the action of the piston 23, so that the rotational movement of the shaft 12 is unlocked. After switching the valve 27 (Fig. 5), the pressure in the communications 28, 31 and 32 is relieved. The working medium, which is located above the pistons of cylinders 7 and 8, can flow through check valves 36 and 37. Now communications 38 - 41 are under pressure, so that cylinders 1 and 2 of the printing apparatus move far away from the plate cylinder 3. If the position of the onset of the onset is set again (Fig. 4), then the working medium located under the pistons of the cylinders 7 and 8 can flow through the sample valve 42. If it becomes necessary to transfer the elements of the printing apparatus to the off position of the onset, then valve 43 must be activated. This working medium for communications 44 and 45 through the choke 46 flows into the valve 47, which switches51
    with a delay in accordance with the slow flow of the working medium and is intended to block the supply of working medium to the piston 23. The switching time can be set by adjusting the drosenel 46.
    Figure 6 shows the valve 47 before switching. Thus, the working medium from communication 38 through communication valve 47 via communication 41 is also supplied to switching valve 34.
    The position of the valve 34 shown in FIG. 6 allows the working medium to be in front of the piston 23 of the brake 18, as a result of which the disks 24 are not in contact with each other.
    After switching valve 47, pressure in communication 41 drops and switching valve 34 moves to a position where pressure in working tank 21 disappears and piston 23 begins to compress the brake discs 24, as a result of which shaft 12 is blocked

    with respect to supports 9 and 10, and consequently, the axle supports 4 and 5.
    At the same time, pressure also drops in communications 39 and 40, so 5 that cylinders 1 and 2 would have to go down. However, brake 18 prevents this.
    If the pressure in the control system is completely off (Fig. 7)
    O cylinders 1 and 2 are in the position reached by them. This also applies to the wide-travel position (Fig. 5). This eliminates damage to the cylinder liner of the system.
    5 clamping, which occurs due to prolonged exposure of the ripeccoBoro cylinder to the plate cylinder during long interruptions in the operation of the machine.
    20 The design features of the proposed device make it possible to exclude uncontrollable movements of the press cylinder due to pressure fluctuations in the working medium when the pressure is off.
