    Electromagnetically operable couplings (10) join the plate cylinder (1-5) to the main drive shaft (6) which is connected to an impulse generator (16) registering in a counter (21) the shaft rotation. A three-phase current drive motor (19) rotates the main drive shaft (6) during the adjusting process. The motor is connected to the main shaft (6) through a free-wheel or clutch (14). The respective control impulse occurs when the counter has logged the impulse number (22) associated with the rotational angle.

    专利说明:

    The invention relates to printing, in particular to rotational multi-color machines and their relative nodes.
    A device for preliminary exhibition of plate cylinders of a multicolor rotary printing machine is known, comprising clutches installed between each plate cylinder and the main drive shaft Ιθ of the machine, and a device for turning each plate cylinder [1J ·.
    When using a well-known device, exhibitions are carried out by sequentially installing a · 1® device for turning on each plate cylinder, having previously disconnected the cylinders from the main shaft through the clutch, and turning each plate cylinder sequentially at the required rotation angle, after which the cylinders are coupled to the main shaft.
    The need for pre-printing cylinders exhibition caused _ in that the distance between adjacent printing units 20 nonmultiple forme cylinder circumference, whereby each subsequent cylinder must be rotated relative to the previous value at residue 1 * obtained by dividing the hoped zapechatyvav- length .mogo web between adjacent plate cylinders on the circumference of the plate cylinder.
    A disadvantage of the known device is the length of the process of exhibition of the cylinders, since it is necessary to manually expose each cylinder sequentially.
    The aim of the invention is to reduce the time for the exhibition of plate cylinders.
    The goal is achieved by the fact that the proposed device for exhibiting plate cylinders has a Pulse sensor kinematically connected to the main shaft and a pulse counter electrically connected to the pulse sensor, each clutch having an electromagnetic drive electrically connected to the pulse counter.
    The device also has an engine for rotating the main shaft of the machine during the exhibition of plate cylinders, connected to the main shaft by means of a coupling.
    The drawing schematically shows the described device.
    A device for the preliminary exhibition of plate cylinders of a lot of 3 colorful rotational printing machines “· '' tires with'o Holds clutches 1-5 installed between the plate cylinders 6-10 and the smooth shaft 11 of the printing machine, a pulse sensor 12 mounted on the shaft 13 connected to the main shaft 11 by means of a clutch 14, and a pulse counter 15, electrically connected to the sensor "! pulses. Each coupling 1-5 is equipped with an electromagnetic drive (not shown in the drawing), electrically connected to a pulse counter.
    The device also includes an engine 16 for rotating the main shaft 11 of the machine during the exhibition of plate cylinders, connected to the shaft 13 by means of 15 gears 17 and 18.
    Shaped cylinders 6-10 are driven from the main shaft 11 by means of gears, each of which consists of two kinematic gears 19 and 20, and reduction gears 21.
    Each plate cylinder is marked 22, for example, in the form of crosses. The frame also has the corresponding markings 23.
    Automatic engagement of the clutch is carried out by means of an intermediate circuit 24.
    The exhibition of plate cylinders is as follows.
    The number of pulses 25 is entered into the pulse counter 15, corresponding to the remainder between the integer number of circles of the plate cylinder and the distance along the printed sheet between the first and second plate cylinders, and the plate cylinder 6 engages with the main shaft 11 by turning on the button 26. After the clutch 14 is turned off, it is switched on by an intermediate circuit 24 engine 16. The sensor 12 generates pulses to the counter 15 until a number corresponding to the entered number of pulses 25 appears in the window 27. Moreover, the coupling is connected to the circuit 24 clutch 2 of the second printing apparatus, the counter 15 is reset to zero and the main shaft 11 is again driven into rotation by the engine. 16. Upon reaching a predetermined number of pulses 25, the plate cylinder 8 of the third printing apparatus, etc., is coupled until the plate qi -._. e- cylinder 10 of the last printing apparatus will not connect to the main shaft
    11. After that, the clutch 14 is disengaged and you can start typing on the machine. Thanks to this preliminary exhibition of cylinders, the markings printed by plate cylinders are located in the fixing area of the printing registration apparatus of the machine and now, without any additional operations, it is possible to print with the correct position of the markings.

    colorful rotary printing machine with erzhitmuf-ga clutch 1-5, installed between the former cylinders 6-10 and the main drive 11 of the printing machine, the sensor 12 imuls, mounted on the shaft 13, connected to the main shaft 11 by means of the clutch 14, and the counter 15 impulses electrically connected to the impulse sensor. Each coupling 1-, 5 is provided with an electromagnetic drive (not shown) electrically coupled to a pulse counter. The device also contains a motor 16 for rotating the main shaft 11 of the machine when the plate cylinders are connected to the shaft 13 by means of gears 17 and 18. The mold cylinders 6-10 are driven from the main shaft 11 by means of gears, each of which consists of two kinematic gears 19 and 20, and reduction gears 21. Each plate cylinder is marked 22, for example, in the form of crosses. The corresponding markings are also affixed to the frame 23. Automatic inclusion of the clutches of the chain is carried out by means of intermediate c we 24 show the printing cylinders osusches is as follows. Pulse counter 15 introduces the number of pulses 25, corresponding to the remainder between the whole number of circles of the form cylinder and the distance Over the printed web between the first and second form cylinders, and the form cylinder 6, by turning on the button 26, engages the main shaft 11. Intermediate circuit 24, engine 16, Sensor 12 sends pulses to counter 15 until the number 27 in the window 27 is equal, which corresponds to the entered number of pulses 25. Moreover, the corresponding connections in circuit 24 include clutches and the clutch 2 of the second printing press, the counter 15 is reset to zero and the main shaft 11 is again driven by the motor. 16. Upon reaching a predetermined number of pulses 25, the forme cylinder 8 of the third executing apparatus engages, and so on, as long as the mold is cy. The lindr 10 of the last printing station does not connect to the main shaft 11. Thereafter, the clutch 14 is disengaged and can be started on the machine. Due to this preliminary exhibition of cylinders, printing marks printed by forme cylinders are located in the area of fixing the print registration device on the machine and now you can print with the correct position of marking marks without additional operations. Claim 1.
