Definitions

  • the invention relates to a register adjusting device for a printing unit with three approximately Y-shaped, plate / blanket cylinder pairs comprising printing units, which have helical gear wheels on their axes, two of which are designed as double gears with opposite pitch on the journal of two blanket cylinders and via a gear are in permanent tooth engagement with one another on the journal of the third rubber blanket cylinder, all cylinders being axially displaceable and the drive being initiated via a gearwheel arranged on a cylinder.
  • a printing unit which preferably comprises three approximately Y-shaped printing units 1, 2, 3.
  • a blanket cylinder 4 and a plate cylinder 5 are provided
  • a blanket cylinder 6 and a plate cylinder 7 and in the printing unit 3 a blanket cylinder 8 and a plate cylinder 9 are provided.
  • the cylinders 5 to 9 each have axle journals mounted on both sides in side walls 20, as is indicated for the cylinders 4, 5, 7, 8, 9 by the reference numerals 10 to 14.
  • a printing carrier web 69 can preferably be provided with a double face print and an impression by the offset printing method.
  • a printing carrier web can be provided with quadruple face printing and double back pressure.
  • the basic setting is similar to that described below.
  • a triple face print ie a three-color print, can be applied in full use of the principle on which the invention is based, with the advantageous setting and readjustment of the side and circumferential register according to the invention having a particular effect for each color.
  • Fig. 2 shows the cylinders 4, 5, 6, 7 mounted in a side wall 20 with their axle journals 10, 11, 12, 21.
  • the cylinders 5 to 9 are driven by means of helical toothed drive gears 22 to 29 advantageously, the drive of a helical gear 68 is firmly connected to the gear 22 on the journal 11 of the cylinder 5.
  • On the journal 10 of the blanket cylinder 4 sits a double gear 23, 24, which drives the gear 26 on the journal 12 of the plate cylinder 7 via a gear 25 on the journal 21 of the rubber blanket cylinder 6.
  • a further printing unit 3 with the cylinders 8, 9 can be arranged above the printing units 1 and 2.
  • the plate cylinder 9 of the printing unit 3 is driven via the gear 27 arranged on its journal 14, which meshes with a double gear 28, 29 on the journal 13 of the blanket cylinder 8.
  • the gear 29 is in engagement with the gear 25 of the blanket cylinder 6.
  • the drive is shown side by side for reasons of clarity, while in practice it is in two planes, i.e. is arranged one above the other.
  • the gears 27, 28 are thus in the plane of the gears 22, 23 and the gear 29 in the plane of the gears 24, 25, 26.
  • the cylinders 4, 5, 7, 8, 9 are each provided with a register actuating device, preferably in the form of a register actuating motor, as indicated at 15, 16, 17, 18, 19. With the register actuators 15 to 19, the cylinders 4, 5, 7, 8, 9 can be axially displaced. According to the invention, therefore, a blanket cylinder, here the blanket cylinder 6, is not provided with a register actuating device, ie with a register actuating motor. In the context of the invention, it is advantageous to initiate the drive, preferably in the form of a gear 68 on the printing unit 1, ie to bring the drive gear 68 into engagement with the gear 22 of the plate cylinder 5.
  • the register setting device comprises 15 to 19 position locking devices, for example linear potentiometers, with the aid of which the lateral position of the cylinders 4, 5, 7, 8, 9 can be determined in each case.
  • a position detection device 30 is thus assigned to the plate cylinder 5 directly or to the register actuator 16 assigned to it.
  • the blanket cylinder 4 to which the position motor 15 is assigned a position detection device 33, while the plate cylinder 9 or its register position motor 19 is assigned a position detection device 40.
  • the cylinders 7 and 8 or their register actuators 17 and 18 are equipped with position detection devices 43 and 62, respectively.
  • the motors 16, 17, 19 are connected to switches 32, 42, 64.
  • two position regulators 34, 44 are used in the register actuating device according to the invention, of which the position regulator 34 can control the servomotor 15 and the position regulator 44 can actuate the servomotor 18.
  • the position controllers 34, 44 are connected to the Position detection devices 30, 40, 62 connected.
  • the position controller 34 receives information via the position detection device 30, ie an electrical signal that provides information about the position of the servomotor 16 or the axial position of the plate cylinder 5, as well as information about the position of the rubber cylinder 4 via the detection device 33, since as at 65 or for the indicated on the cylinders at 66 and 67 due to the helical drive, there is a mechanical or positive connection between the cylinders 4 and 5.
  • the plate cylinder 5 when the plate cylinder 5 is axially displaced, the latter rotates and, since the drive gear 68 does not rotate, the rotation of the plate cylinder 5 as a result of its axial displacement via the gear 22 causes a change in the circumferential register.
  • the axial position of the plate cylinder 5 is indicated by the position detection device 30 on the display instrument 31 and the axial position, the blanket cylinder 4 on the display instrument 35. If the plate cylinder 5 now rotates due to axial displacement, this is communicated to the position controller 34 by the position detection device 30, which in the same Directs an axial displacement via the actuator 15 for the blanket cylinder 4, so that the rotation of the plate cylinder 5 is compensated.
  • a side register adjustment of the plate cylinder 5 is possible, which automatically results in a compensation of the change in the circumferential register caused thereby.
  • a servomotor 37 which together with the potentiometer 36 constitutes a so-called motor potentiometer, activates the position controller 34 by actuating a switch 38, so that the register servomotor 15 is activated correspondingly axially moves the blanket cylinder 4.
  • the side register of the plate cylinder 7 is carried out by its axial displacement by means of the register servomotor 17.
  • the resulting rotation can now only affect the plate cylinder 9 via the cylinders 6 and 8 if this circumferential rotation of the plate cylinder 7 is compensated for by axial displacement of the cylinder 6; ie the circumferential setting of the plate cylinder 5 is no longer changed.
  • the side register of the plate cylinder 9 is now set thirdly by means of its axial displacement, there is only a rotation of the circumference of the plate cylinder 9. This also means that the circumference of the plate cylinder 5 is no longer changed.
  • the influence on the plate cylinder 7 is compensated. So first the side register of the plate register 5, then the side register of the plate cylinder 7 and then the side register of the plate cylinder 9 is set. Taking into account the fact that the plate cylinder 5 is held circumferentially as a result of the drive gear 68, compensation for the circumferential register setting or subsequent correction of the side register settings of the plate cylinders 5, 7, 9 results from the fact that circumferential displacement of the blanket cylinder 4 by axial displacement the plate cylinders 7 and 9 on the circumference of the plate cylinder 5 adjustable, that is. are readjustable. If the circumferential register of the plate cylinder 9 differs, compensation or adjustment is carried out in that the blanket cylinder 8 is axially displaced.
  • the rotation of the plate cylinder 7 takes place by the axial displacement of the blanket cylinder 4, which, as already mentioned, the plate cylinder 5 can not rotate, so that by its shift caused rotation itself affects only as a rotation of the plate cylinder 7 and a rotation of the plate cylinder 9 also does not take place, since the blanket cylinder 8 is pushed in the same axial direction as the blanket cylinder 4, so that the axial displacement of the blanket cylinder 4 for adjusting the circumferential register of the plate cylinder 7 does not affect the circumferential register of the plate cylinder 9 affects.
  • the setting of the peripheral register of the plate cylinder 5 is shown in FIG. 3, while the setting of the peripheral register of the plate cylinder 9 is shown in FIG. 4. 4, the side position of the plate cylinder 9 is again detected by means of the associated position detection element 40, the value of which is displayed on the instrument 41.
  • a displacement of the plate cylinder 9 or the associated register servomotor 19 is communicated via the position detection device 40, which communicates this value, which is also indicated at 41, to the position controller 44.
  • the peripheral register of the plate cylinder 9 is set by the position controller 44 via the register servomotor 18 or the rubber blanket cylinder 8.
  • the target value for the circumferential register of the plate cylinder 9 can be set by the potentiometer 46, a desired circumferential register value on the plate cylinder 9 being adjustable by actuating the switch 48 and thus the servomotor 47.
  • both position controllers 34, 44 must be activated, which was indicated by the switch 49, if the circumferential register of the plate cylinder 7 is to be set, since, as has already been described above, the blanket cylinders 4 and 8 are axially displaced in this case Need to become. It is therefore sufficient to use only two position controllers 34, 44 for the circumferential register setting of the plate cylinders 5, 7, 9, which are activated individually according to FIGS. 3 and 4 for the circumferential register setting of the plate cylinders 5 and 9, while they are activated together must if the circumferential register of the plate cylinder 7 is to be set according to FIG.
  • FIG. 6 which comprises a microcomputer or microprocessor 50
  • All actual values of the five cylinders are shown to it by the position detection devices 30, 62, 40; 33, 43 forwarded.
  • the microprocessor 50 processes the target and actual values in accordance with the preceding descriptions and sends the actuating signals to the register actuators 15 to 19 in the manner described above.
  • the circumferential register adjustment of the cylinders 5, 7, 9 can be described in FIG This is done in such a way that the circumferential register of the plate cylinder 5 by shifting the blanket cylinder 4, the circumferential register of the plate cylinder 7 by shifting the blanket cylinder 4 together with the blanket cylinder 8 and the setting of the circumferential register of the plate cylinder 9 by shifting the blanket cylinder 8.
  • a further advantage of the circuit according to FIG. 6 is that in addition to displaying the setpoint and actual values by means of the feedback display 51 on a setpoint indicator 52 and an actual value indicator 53, an operating keyboard 54 is connected to the microprocessor.
  • This can advantageously have three buttons 55, 56, 57 for the three colors to be printed on one side of the print carrier web 69. If, for example, the first color is to be set in terms of the side and circumference registers, the button 55 is actuated, after which the circumferential registers on the corresponding plate cylinder in the forward and backward direction by means of the Keys 60, 61 and the side register, that is adjustable in the left and right directions by means of the buttons 58, 59.
  • the drive i.e. to introduce the drive gear 68 via the drive gear of the plate cylinder 7 or 9, only the setting sequence changing, which can be determined by simple considerations taking into account the preceding description.
  • the drive can be introduced via the blanket cylinder 6 or in each case via the blanket cylinder, which has only a simple, that is to say no, double gear, although it is somewhat disadvantageous that in this case the blanket cylinders 4, 6, 8 are separated when they are switched off certain problems can occur from each other as a result of the drive.
