    The invention relates to a drive for a printing apparatus of a rotary printing press, in which the transfer roller is located between the duct roller and the first ink transfer roller.
    In the C * inkjet apparatus, the transfer roller lasts for a short time on a slowly rotating duct roller and on the first grinding cylinder 0 rotating at a printing speed. The transfer roller which is not directly driven, is interested in the collector inking cylinder is rotated during transmission over it or Me- 15 narrow bands of paint, thus arising due to friction. After a continuous movement, the transfer roller is adjacent to the first grinding cylinder. at this moment, the energy consumption 20 for the instantaneous acceleration of the transmission shaft acts as a shock, leading to a number of unpleasant phenomena that worsen the quality of printing.
    The measures according to U5 3 002 451, in which the connection of the drive between the printing cylinder and the rollers of the ink unit is carried out relatively smoothly through roller chains or the like, lead only to a certain cushioning of said drive shock. To more fully avoid the impact of f from DE ~ 05 2 03 1 504, a colorful apparatus is known which has a motor for accelerating the transfer roller. The transfer roller is accelerated during the lifting movement by means of a special drive roller located with it in the frictional connection so that the impact load arising at the moment of the rolling roller contact in the paint apparatus is minimized.
    In the device according to the indicated DE-OS, along with other disadvantages, disadvantages appear due to the high technical complexity and due to the fact that
    94301.3 a drive shaft belonging to the transfer roller is outside the ink stream and thereby acts as an undesirable ink accumulator. As a result of this, the ink apparatus, with the necessary § corrections of the quantity and profile of the ink, becomes inert, i.e. change settings on a colorful knife, etc. reflected only after some time in printed matter. 10
    By eliminating this drawback according to US Pat. No. 3,688,696, the acceleration drive is designed so that the engine that drives the transfer roller through two V-belts, is turned on when the transfer roller rises from the duct roller. In this case, the engine speed is set during the lifting movement of the transfer roller so that the transfer roller has a relatively high peripheral speed before it reaches the first paint transfer roller. The engine is connected to a tachometer that turns off the engine when the intended rotation speed is reached.
    The disadvantage of this device is also high technical costs. At normal speeds of rotation of modern rotary printing machines. the duty cycle on the transfer roller lasts only about 0.5 s, E1 acceleration time, i.e. the time of movement of the transfer roller between the duct roller and the first grinding cylinder is of the order of tenths of a second. Thus dviga- 3 Tel has a large load and the device is unreliable.
    The purpose of the invention is the creation of a colorful apparatus with a transfer roller, which removes unwanted vibrations from the printing cylinder,
    The invention is based on the problem, the creation of the inking unit without special drive for the transfer roller, wherein the transmitted first distribution cylinder at each operating cycle kick acceleration is not transmitted to the whole inking unit or on its actuating a kinematic chain and a heme SAGT on of Great 5 duschie gears of a printing cylinder.
    Ego is achieved by the fact that the driving gear of the first grinding cylinder is connected directly, i.e. through 5 a special kinematic chain with a main drive shaft and between the first grinding cylinder and the second grinding cylinder, a roll roller driven only by friction is located.
    The cam mechanism for the movement of the transfer roller or ^ / and for the duct roller may be included in direct connection with the main drive shaft.
    Colorful apparatus with transmission vg. first of all, it has the advantages that the high complexity to achieve extremely short-term acceleration of the transfer roller during the movement of the transfer roller is avoided, the increase in the torque allocated to the main drive shaft due to the ratio of the drive stiffness', and ·: the shaft cannot lead to interference affecting the quality of printing, and that the impact of the rotation moment is reduced due to the slip and elasticity of the transmitting rubber roller so much that no more fucking in the rest of the colorful apparatus and, thus, in the printing cylinder.
    In FIG. 1 - schematically shows a colorful apparatus and part of the upper half of a double-sided printing machine and a zero rotary offset machine; in FIG. 2 - the drive mechanism of FIG. 1; in FIG. 3, the drive of FIG. 2, side view.
    Between the side walls of the machine bed 1 are located above and below the web 2 offset cylinders 3 and 4 and plate cylinders 5 and 6. Each plate cylinder has a colorful apparatus. The paint from the ink box 7 is transferred in strips by a duct roller 8 to a transfer roller 11, a reciprocating cam 9 and a contact roller 10. From the transfer roller 11, the paint enters the first rastyruchny cylinder 12 through the rolling roller 13, the grinding cylinders 14 and additional rolling rollers, on rolling rollers 15 and, thus, on the plate plate of the plate cylinders 5 and 6.
    In Fig. 2, kinematic chains are shown. The main drive shaft 16 through the driving gears of the offset cylinders 4, 3 and the driving gears of the plate cylinders 5 ', 6' are only grinding wheels of the ink apparatus to the driving gear 14, In contrast, the driving gear 12 * of the first grinding cylinder 12 and the drive gear of the cam 9 are connected through respective intermediate gears, which are necessary, in particular, to achieve the desired gear, and are connected directly to the main gear via an additional drive roller 17 5 drive shaft 16.
    Instead of a transmission mechanism consisting of bevel and cylindrical wheels with a heme effect, it is also possible to carry out a separate drive through "O chain transmissions or toothed belts." Instead of the motor 18 in the drive of the drive roller 8, the drive gear of the ink apparatus 8 ’can be connected via corresponding intermediate 5 wheels, for example, with the gear drive of the cam drive 9,

    The invention relates to a drive for an edge apparatus of a rotary printing press, in which a transfer roller is located between the ductor roller and the first ink transfer roller. In the inking unit f, the rollers are transferred to the roller for a short time against a slowly rotating spinner and to the first grinding cylinder, which rotates at a printing speed. The transfer roller, which is not directly set in motion, is carried into rotation by the ductor roller during the transfer of more or less narrow strip of paint, due to the resulting friction. After a sweeping motion, the transfer roller abuts on the first rubbing cylinder. At this point, the energy consumption of the instantaneous acceleration of the transmission shaft acts as a shock, leading to a number of unpleasant, degrading printing quality. Measures according to US Pat. No. 3,002,451, in which the drive connection between the printing cylinder and the inking rollers is relatively smooth through roller chains or the like, is suitable only to a certain damping of said volunteer vapor. For a more complete avoidance of impact from DE05 02 03 1 504, a paint apparatus is known, which has a motor for accelerating the transfer roller. The transfer roller is accelerated during the lifting movement by means of a special drive roller which is in the friction connection so that the pulsation in the dyeing unit at the time of the contact of the rolling roller is minimized. In the device indicated by the TJE-OS, among other drawbacks, there appeared disadvantages of high tech complexity and because 394 drive shaft, which is attached to the transfer roller, is out of paint tioToKa and, thus, acts as an undesirable paint accumulator. As a result, the inking unit with the necessary adjustments of the quantity and the ink becomes inert, i.e., and &amp; changes the settings on the colorful knife, etc. they are reflected only after some time on printed matter. This deficiency has been eliminated according to US 3 688 696, the accelerator drive is designed so that the engine which drives the transfer roller in; the motor O1e through two clinches: phemn, is turned on when the transfer vlik is under (n, from the ductor roller). This is set up in the lift movement of the hypersingum roller so that the transfer roller (s) has a relatively high peripheral speed before it reaches the first paint roller, the motor is connected to a tachometer that turns off the motor Spruce when reached (the intended rotation speed is a disadvantage of this device; also high technical costs. At normal rotation speeds of modern rotary printing machines, the duty cycle on the transfer roller is only about 0.5 s. The acceleration time, i.e. Moving the transfer mill between the duct roller and the first ramming cylinder is about ten seconds long, so the engine is heavily loaded and the device is unreliable. The purpose of the invention is to create an inking apparatus with a pepper mill which removes undesirable oscillations from the printing cylinder. The invention is based on the task of creating an inking machine without a special drive for the transfer roller, in which the acceleration impact transmitted to the first rast1 cylinder is not transmitted to the entire paint device or to its drift kinematic chain and, gears of the printing cylinder. This is achieved by the fact that the drive gear of the first grinding cylinder is directly connected, i.e. through a special kinematic chain with the roller shaft and between the first grinding cylinder and the core and the second grind of the cylinder Cylinder 34 is a roll roller driven by friction only.The cam mechanism for moving the transmission roller is 1} and for the ductor roller it can be included in direct connection with the main shaft of the drive roller. before, the advantages that high complexity to achieve extremely short-term transfer speeds during movement 1 and transfer roller are avoided, deviate to main 1st section drive shaft pop-up point of time 1 thanks to the value of to stiffness, T; the shaft can not cause (: xpm, affecting print quality, and that the impact of the moment of rotation mixes the weights due to the glide and wpyrocity of the transfer rubber roller so much that it doesn’t excite oscillations in the rest of the inking device any more and, thus, in cylinder m.
