Definitions

  • the invention relates to a pressure switching device according to the preamble of claim 1.
  • the blanket cylinder can be switched on and off relative to the impression cylinder using a so-called two-stage manual gearbox, with constant contact with the plate cylinder, and in a second step it can also be switched on and off from the plate cylinder.
  • the known pressure shift transmissions both in the printing units of sheet-fed offset printing machines and in the known coating devices or coating units have actuating devices which can be acted upon by pressure medium, in particular in the form of pneumatic cylinders, in order to generate the starting and stopping movement.
  • actuating devices which are designed as working cylinders, are attached to one side of the machine (A-side or B-side) and act on a moving-off shaft extending between the side frame walls carrying the cylinders.
  • This move-off shaft is connected directly to the pivotable eccentric bearings of the cylinder which can be turned on and off via levers attached to the end thereof and possibly still intermediate gear links.
  • a so-called double-acting, single-stage working cylinder (pneumatic cylinder) is used as the actuating element, by means of which the forme cylinder can be turned on and off the impression cylinder.
  • the center distance of the forme cylinder with respect to the impression cylinder can be adjusted, which serves to adapt to different substrate thicknesses.
  • the mechanism described above for a printing unit of a sheet-fed offset printing machine usually differs only in that a so-called two-stage, double-acting working cylinder is used as the actuating device in order to pivot the two eccentric bearings of the blanket cylinder in a total of three positions via the moving shaft, in a first position the blanket cylinder is turned on both the plate and impression cylinder, is turned off in a second position with constant contact to the plate cylinder from the impression cylinder and in a third position is turned off both the impression cylinder and plate cylinder. Also in the case of the pressure switching devices in sheet-fed offset printing units, adjusting devices are assigned to these printing switching mechanisms, by means of which a change in distance dependent on the substrate thickness can be achieved by correspondingly pivoting the eccentric bearing of the blanket cylinder.
  • a disadvantage of the previously described pressure switching devices for printing units of sheet-fed offset printing machines or for coating devices / coating units of sheet-fed offset printing machines is that a moving-off shaft extending between the frame walls is provided, via which the pivoting movement of the eccentric bearings on the A and B sides of an actuating element outgoing is effected. If such a pull-off shaft runs in the vicinity of the printing zone between the blanket cylinder and the impression cylinder or the printing zone between the forme cylinder and the impression cylinder (coating device / coating unit), there is a risk that the incoming or outgoing sheet will come into contact with this transfer shaft and possibly lubricate . As a result, additional measures for the printing material guidance are required, which increases the structural complexity.
  • DE 4 401 289 A1 discloses a cylinder activation and deactivation method together with a corresponding device for two pressure cylinders, in which the eccentric bearings carrying the adjustable cylinder are pivoted by an actuating device and this interacts with an adjustable stop.
  • the appropriate setting of this stop means that the cylinder is adjusted in relation to the printing material thickness relative to the cylinders interacting with it.
  • a disadvantage of the pressure switching device known from this document in addition to the large number of necessary parts set out in the variants described, is also that simple transfer to coating devices / coating units or sheet-fed offset printing units because of the above-described problem of lubricating a sheet on an area between A- and B- Side extending shaft is not possible.
  • this pressure switching device acts either indirectly (for example with the interposition of a gear pair) on the one or more eccentric bearings or the interaction to the pressure position defining stop with the corresponding swivel mechanism is chosen structurally unfavorable. Furthermore, an inclined position of the cylinders against each other (different line pressure across the format width) is not possible when the machine is running.
  • the object of the present invention is therefore to develop a pressure switching device according to the preamble of claim 1 in such a way that, while avoiding the disadvantages mentioned above, a cost-effective and flexible setting option is created.
  • both on the A and on the B side of the printing press both the pivoting of the respectively assigned eccentric bearing acting actuating element and an adjusting device for each with the Actuator cooperating stop is provided.
  • the actuating elements on the A and B sides are triggered simultaneously for pressure switching.
  • the setting devices arranged on the A and B sides are activated at the same time.
  • the actuators adjusting the stops can also be controlled by different position amounts, so that an intended inclined position of the forme cylinder or the blanket cylinder can be achieved with respect to the counter-pressure cylinder interacting with it.
  • This serves to adapt the line printing to the printing material or depending on the subject to be printed.
  • a setting of the form or blanket cylinder which is different over the format width and in particular stronger on one side the impression cylinder is used in particular in coating devices or coating units in order to produce, for example, a uniformly strong coating film on the printing substrate.
  • the present invention can be used both in coating devices or coating units, in which a forme cylinder is arranged on and off with respect to a sheet-guiding impression cylinder, and in the printing units of sheet-fed offset printing presses, in which a blanket cylinder is arranged opposite the impression cylinder and the plate cylinder. and can be switched off.
  • a two-stage, double-acting working cylinder is advantageously used as the actuating device on the A and B sides.
  • FIGS. 1 to 4 show, for example, the A side of the pressure switching device according to the invention on a printing unit (not shown) of a coating device, a coating unit or a sheet-fed offset machine.
  • a cylinder 1 is rotatably received in eccentric bearings 2 on the A and B sides of the printing unit via the pins, these eccentric bearings 2 being pivotable in side walls (not shown) of the printing unit are stored.
  • the center of the cylinder 1 is identified by MZ and the center of the eccentric bearing 2 by ML (pivot or rotation axis).
  • the eccentric bearings 2 on the A and B sides each have a lever 3 in the form of an arm, on the free end of which the piston rod of a one- or two-stage double-acting working cylinder 4 is articulated.
  • the working cylinder 4 is supported on the frame with an articulation point.
  • the levers 3 of the eccentric bearings 2 are each assigned an adjustable stop 6 via an actuator 5, so that the pivoting movement of the eccentric bearings 2 / the lever 3 each in the extended position of the piston rod of the working cylinder 4 can be limited. In the position according to FIG.
  • the lever 3 of the eccentric bearing 2 bears against the stop 6 of the actuator 5 (A and B side), which corresponds to the so-called print-on position, in which (except for one due to the substrate thickness) conditional distance) the cylinder 1 (blanket cylinder / forme cylinder) is placed against the cylinder or cylinders interacting with it.
  • the actuator 5 or the stop 6, which is adjustable by the actuator 5 relative to the lever 3 of the eccentric bearing 2, can be an electrically remote-controllable spindle drive, the rotatable threaded spindle being rotated through a correspondingly fixed threaded piece.
  • FIG. 1 shows the position in which the cylinder 1, in the extended position of the piston rod of the working cylinder 4, bears against the stop 6 of the frame drive 5 (push-on position), the piston rod of the working cylinder 4 and thus the eccentric bearing 2 can be retracted the cylinder 1 can be turned off.
  • a further stop 7 (each on the A and B side) can be arranged fixed to the frame as additional end position damping.
  • FIG. 3 shows the position in which the cylinder 1 is completely turned off from the cylinder or cylinders interacting with it by correspondingly pivoting the eccentric bearing 2 (at stop 7).
  • the piston 1 of the working cylinder 4 is extended and the cylinder 1 is turned on by the lever 3 again in contact with the stops 6 of the actuators 5 located on both the A and B sides is driven.
  • the working cylinders 4 (A and B side) are acted on simultaneously or synchronously.
  • the actuation of the actuators 5 on the A and B sides can limit (at the same time) the stroke of the piston rod of the working cylinder 4 when it is extended and thus the pressure on it.
  • moving the actuators 5 in the same direction on the A and B sides results in an overall parallel axis distance adjustment of the cylinder 1 with respect to the cylinder or cylinders interacting with it.
  • it can also be provided, e.g.
  • FIG. 4 An embodiment of the pressure circuit according to the invention in the form of a one-stage pressure circuit was described above with reference to FIGS. 1 to 3.
  • the working cylinders 4 were consequently designed as so-called single-stage, double-acting working cylinders.
  • the use of two-stage, double-acting working cylinders results in a two-stage printing circuit in which, for example, a blanket cylinder of an offset printing unit can be switched on and off both with respect to the impression cylinder and with respect to the plate cylinder.
  • a blanket cylinder of an offset printing unit can be switched on and off both with respect to the impression cylinder and with respect to the plate cylinder.
  • FIG. 4 Such a position is shown in FIG. 4, the piston rod here Working cylinder 4 assumes the so-called center position and consequently the levers 3 of the eccentric bearings 2 have neither contact with the stops 6 nor with the stops 7.
  • FIG. 5 shows the possible positions of a blanket cylinder G in relation to the impression cylinder D and plate cylinder P of an offset printing unit.
  • the arc-shaped printing material resting on the impression cylinder D is also indicated.
  • the so-called print-on position is shown at the top left in FIG. 5, in which the blanket cylinder G makes contact both with the plate cylinder P and with the impression cylinder D.
  • To the right of this is shown a position in which, by pivoting the eccentric bearings 2 (FIGS. 1 to 4) in the same direction, the blanket cylinder G is more strongly engaged with the impression cylinder D with constant contact with the plate cylinder P. This corresponds to a stronger pressure supply of the rubber blanket cylinder G compared to the impression cylinder D.
  • the positions of the rubber blanket cylinder G with different provision (center distance) relative to the impression cylinder D correspond to the positions of the eccentric bearings 2 according to FIGS. 1 and 2.
  • the first print-down position is described at the bottom left in FIG. 5, in which the blanket cylinder G is switched off from the impression cylinder D by corresponding actuation of the working cylinder 4 (FIGS. 1 to 4), but still has contact with the plate cylinder P.
  • Such a position of the rubber blanket cylinder G corresponds to the position of the eccentric bearing 2 according to FIG. 4.
  • the pivoting of the eccentric bearing 2 causes a further movement of the blanket cylinder G so that it is now also turned off from the plate cylinder P. This corresponds to a pivoting of the eccentric bearings 2, starting from FIG. 4 to the position according to FIG. 3.
