Definitions

  • the invention relates to a device for driving a roll of a rotary printing machine, in particular an applicator roller of a painting device, wherein the roller is driven by the main drive of the printing press and additionally by an independent from the main drive of the printing press auxiliary drive.
  • rollers of painting equipment in rotary printing presses must be driven even when the printing machine is stationary or printed without painting. This prevents that the paint can dry on the rollers and thus they are unusable.
  • an independent auxiliary drive is therefore provided which keeps the painting device in motion during the remaining phases of operation.
  • the invention has for its object to provide a device of the type mentioned, in which the roller does not lag when stopping the printing press and an associated risk of injury is avoided. Furthermore, the roller should not have to be stopped when switching from auxiliary drive to direct drive by the printing press.
  • a superposition gear is provided for driving the roller through which the roller is permanently coupled to the main drive of the printing press and to the auxiliary drive.
  • the superposition gear is preferably designed so that the main drive is primarily for driving the roller, so that when stopping the printing machine, e.g. in an emergency stop, at the same time as the printing press and the roller is stopped. The risk of injury by running the roller of the painting is thus excluded, so that can be dispensed with the attachment of special protection devices.
  • Another advantage of the superposition gear is that when the auxiliary drive is running, the main drive and the main drive of the auxiliary drive can be switched on, without it previously requires a shutdown of the roller.
  • the auxiliary drive can be switched on before the roller has come to a standstill in order to achieve in this way, the running of the roller with low, safe for the operator rotation speed.
  • the roller of the painting is not stopped, but it is delayed when stopping the printing press to the relatively low input speed of the auxiliary drive by the machine drive and then kept in rotation by the auxiliary drive. This can be useful if the press is shut down without stopping the machine.
  • the stopped printing press can be approached with the auxiliary drive running and correspondingly slowly rotating roller without special precautions, wherein the roller of the painting is accelerated smoothly. This considerably simplifies and accelerates the start of the machine.
  • the inventive use of a superposition gear has also the advantage that with the aid of the auxiliary drive, the rotational speed of the applicator roller of a painting can be increased or decreased during operation of the printing press to produce a defined slip between the applicator roll and the associated form cylinder in production and to change the transfer behavior of the applicator roll. It is possible by changing the direction of rotation of the auxiliary drive to operate the application roller both leading and lagging relative to the forme cylinder.
  • the superposition gear is preferably designed so that when the auxiliary drive is stationary, the ratio between the forme cylinder and applicator roller 1: 1. If the auxiliary drive is switched on, then the transmission ratio can be increased or decreased depending on the direction of rotation of the auxiliary drive.
  • the transmission ratio between auxiliary drive and applicator roller is preferably 1: 25 to 1: 300. In this way, the appropriate rotational speed of the applicator roller can be achieved at standstill of the printing press at normal drive speeds of an auxiliary drive motor. For speed increases by connecting the auxiliary drive during the printing operation, it may be appropriate to change the drive speed of the auxiliary drive by appropriate control of the auxiliary drive motor. Likewise, if necessary, the direction of rotation of the auxiliary drive can be changed.
  • the painting apparatus shown in Figure 1 comprises a sheet leading impression cylinder 1, a formable to this form cylinder 2, an engageable on the forme cylinder 2 and can be set off by this application roller 3 and cooperating with this chamber doctor blade 4 for supplying the paint to be applied.
  • On the form cylinder 2 is usually mounted either a printing plate or a blanket.
  • the application roller 3 is screened. Due to the depth of the screening, the scoop volume of the applicator roll 3 is determined.
  • Figure 2 shows the device for driving and the drive-side mounting of the applicator roll 3.
  • an eccentric bearing 6 is rotatably mounted in a side frame 5 of the painting.
  • a lever 7 is rotatably connected, which extends parallel to the side frame 5 and is connected at its free end to a supported on the side frame 5, not shown actuator. With the help of the actuator, the lever 7 can be pivoted to on and off the applicator roll 3.
  • a shaft 8 is rotatably mounted, which has a split bearing shell 9 on the inside of the side frame.
  • a cylindrical end portion 1 o of the applicator roll 3 is arranged.
  • the bearing shell 9 is closed, the end portion 10 is clamped in a rotationally fixed manner in the bearing shell 9.
  • the shaft 8 is fixedly connected to an output of a superposition gear 11.
  • the superposition gear 11 has a rotatable, cylindrical housing 12 and on the side facing away from the shaft 8 coaxial with this an input shaft 13 which is rotatably connected to the drive shaft 14 of a motor auxiliary drive 15.
  • a transmission technology coupling between the auxiliary drive 15 and the input shaft 13 of the superposition gear 11 may be provided.
  • the input shaft 13 is rotatably mounted in a rolling bearing 16 which is held together with the housing of the auxiliary drive 15 on a plate 17.
  • the plate 17 is fixed by means of stud bolts 18 on the side frame 5.
  • the cylindrical housing 12 of the superposition gear 11 carries on its lateral surface a gear 19, which is in engagement with the gear train 20 of the main drive of the painting or the printing press.
  • the authoritative for the drive of the applicator roller 3 section of the gear train 20, the gear 19 and the superposition gear 11 are designed so that when stationary auxiliary drive 15, the peripheral speed of the forme cylinder 2 and the applicator roll 3 are the same.
  • the gear ratio of the superposition gear 11 is close to 1. If the gear 19 is stationary and drives only the auxiliary drive 15 to the applicator roll 3, the superposition gear 11 acts under a reduction, the gear ratio preferably 1 : 25 or greater. Since the transmission ratio also determines the ratio of the torques of the drive and output, the auxiliary drive can be made relatively small by this design of the superposition gear.
  • the auxiliary drive 15 via the superposition gear 11 to prevent drying of the paint on the applicator roll 3.
  • the main drive of the printing machine holds on the gear 19, the housing 12 of the superposition gear 11, so that the rotational speed of the applicator roller is determined exclusively by the auxiliary drive 15 with the associated gear ratio of the superposition gear 10.
  • the housing 12 of the superimposed gear 11 is moved via the gearwheel 19 set in rotation and thereby accelerates the applicator roll 3.
  • the auxiliary drive can now be switched off and shut down, whereby the peripheral velocities of applicator roll 3 and form cylinder 2 equalize. If this state is reached, the applicator roller 3 is employed on the forme cylinder 2.
  • the drive of the applicator roller 3 is now carried out exclusively by the main drive, wherein optionally the voltage applied to the input shaft 13 reaction torque is absorbed by the stationary auxiliary drive 15.
  • the applicator roller 3 may be desirable to allow the applicator roller 3 to advance or lapse to change the transfer behavior, i. To increase or decrease the peripheral speed of the applicator roll 3 with respect to that of the forme cylinder 2.
  • this can be achieved in a simple manner by the auxiliary drive 15 is additionally driven, either in a rotational movements of the main drive and auxiliary drive adding or subtracting the rotational movements of the main drive and auxiliary drive rotation.
  • the slip between the application roller 3 and the forme cylinder 2 can also be set to the required level.
  • the described design of the drive of the applicator roller of a painting device is simple in construction and allows a particularly simple control, since except the control of the auxiliary drive no additional control commands needed for switching clutches or the like.
  • Suitable superposition gear units are available as ready-to-install units and can therefore be used without significant development and production costs.
