Definitions
- Electrographic printing or copying devices are e.g. known from US 6 072 977. You assign e.g. a photoconductor drum as an intermediate carrier on which a charge image of the on a recording medium, e.g. a paper web, image to be printed is generated. The intermediate carrier is then moved past a developer station, through which the charge image on the intermediate carrier is colored with toner. The toner image is transferred from the intermediate carrier to the recording medium in a transfer printing station and then fixed in a fixing station. This completes the printing or copying process for an image. The intermediate carrier is unloaded and is then available for a new printing or copying process.
- a photoconductor drum as an intermediate carrier on which a charge image of the on a recording medium, e.g. a paper web, image to be printed is generated.
- the intermediate carrier is then moved past a developer station, through which the charge image on the intermediate carrier is colored with toner.
- the toner image is transferred from the intermediate carrier to the recording medium in a transfer printing
- the toner image should be transferred from the intermediate carrier to the recording medium as error-free as possible.
- Print image errors in the transfer printing processes used today in continuous presses in the speed range up to approx. 1.5 m / s consist primarily in the occurrence of imperfections (data loss) or brightening in grid areas, in unsharp grid areas, and horizontal stripes in grid areas on the recording medium ,
- the second printer of a twin system or the third printer of a triple system, etc.
- curled, shrunk, with loss of moisture is particularly critical must print.
- the state of the art in continuous printers is transfer printing with a transfer corotron, for example from DE 197 49 386 C2. knows.
- the record carrier is guided past the intermediate carrier in the transfer printing area without additional contact pressure and with the help of the transfer corotron the printed image is transferred from the intermediate carrier to the record carrier.
- the force generated by the electric field between the transfer corotron and the toner on the intermediate carrier is often not sufficient to completely transfer the toner to the recording carrier in the case of a wavy recording medium. This results in print image errors such as imperfections and raster blurring.
- the recording medium can suddenly slip through in an uncontrolled manner. This is shown by horizontal stripes in grid areas.
- WO 02/077719 AI it is known (WO 02/077719 AI) to use a transfer roller as transfer printing which presses the recording medium onto the intermediate carrier in the transfer printing area. Structure and function of such a transfer printing station can be found in WO 02/077719 AI, to which reference is made and which is hereby incorporated into the disclosure.
- the transfer station is designed there so that this principle can also be used with high-speed printing or high-speed copying machines. To do this, the recording Media carrier in the transfer printing area rests securely on the intermediate carrier, there are no jumps in the relative speed between the recording medium and the intermediate carrier in printing operation and no print image errors occur on the recording medium.
- the following disturbances may occur in 'a transfer printing station with the transfer roller: part tolerances, eccentricities (photoconductor, transfer roller), temperature fluctuations, dirt, wear (photoconductor, transfer roller), variable web tension in the recording medium, asymmetrical to the transfer roller train, different thickness, stiffness , Ripple of the recording medium. It must be taken into account, for example, that the transfer roller and intermediate carrier must be replaced and that the transfer must then be flawless.
- the problem to be solved by the invention consists in specifying a transfer printing station with a transfer roller which functions perfectly under variable environmental conditions.
- the transfer roller can be moved exactly by the drive unit. In this way, relative speeds between the recording medium and the intermediate carrier are avoided when swiveling in and out.
- a constant pressure force of the transfer roller on the intermediate carrier is guaranteed.
- the pressure force can be adjusted depending on the properties of the recording medium.
- At least one compensating device can be provided in the transfer printing unit, which acts unevenly across the width of the transfer roller can be and thus compensates for tolerances in the transfer roller or intermediate carrier.
- two or more compensation devices can also be used.
- the drive unit thus compensates for unbalance, radial runout or changes in thickness in the recording medium uniformly over the width of the intermediate carrier.
- a motor can be used as the drive unit, which can work in the position-controlled mode and in the torque-controlled mode.
- the motor can be a rotary motor, e.g. a brushless DC motor, or a linear motor.
- the transfer printing unit has a pressure bar mounted on one side, on which the transmission element engages, and at least one, expediently at least two, bearing rocker mounted on the pressure bar, in which the transfer roller is mounted.
- the bearing rockers and the pressure bar can be rotatably mounted about a common pivot bearing.
- the bearing rockers are also movable about the axis of rotation relative to the pressure bar, so that the transfer roller can lay parallel to the intermediate carrier.
- at least one compensating device can be tensioned or relaxed.
- the transfer printing unit, and with it the transfer roller can be pivoted or pivoted away by the transfer element onto the intermediate carrier.
- the pivoting process can be achieved in that the transmission element is connected via a coupling arm to an eccentric which is arranged on the drive shaft of the drive unit.
- the at least one compensating device exerts pressure in the direction of the intermediate carrier.
- the compensation device can consist of resilient elements, for example.
- the drive unit then uniformly compensates for the radial runout across the width of the transfer roller (transfer roller remains parallel to the axis of rotation). If two compensating devices are provided, one for each rocker arm, these act non-uniformly across the width of the transfer roller, namely at the front and rear with different radial impacts, that is, wobble and inclination of the transfer roller to the intermediate carrier.
- the pressure bar can be provided with a deflection roller for the recording medium.
- This deflection roller can create a tangential web run to the intermediate beam in the ON position. If the deflection roller is arranged on the pressure bar, the compensation device does not act on the deflection roller.
- record carrier webs that do not run symmetrically to the transfer roller can also be processed, since the deflection roller cannot lift off on one side when the web is pulled, i.e. the axis of the deflection roller remains parallel to the axis of the intermediate beam.
- the transfer roller does not lift off on one-sided web tension, since the wrap angle of the record carrier on the transfer roller is almost zero and therefore hardly any forces from the web tension react on the compensation devices.
- the deflecting roller By arranging the deflecting roller appropriately, it is possible to guide the recording medium tangentially past the surface of the transfer roller and a drum-shaped intermediate carrier. Such guidance can also be achieved if rollers or jaws are arranged in a corresponding manner in the deflection unit.
- the advantage of such The management of the recording medium is that the toner flying is minimized and the printed image is more uniform.
- the transfer printing station according to the invention is particularly suitable for printing devices which print on a tape-shaped recording medium at high speed and in which the intermediate carrier is a photoconductor drum.
- the angle by which the drive shaft is to be moved from the DOWN position to the ON position can be determined with the aid of a position counter, a first or second counter reading being assigned to the DOWN position or the ON position.
- the second counter reading acts as a setpoint or control specification for torque control. If a defined position deviation is exceeded, the torque can be adjusted.
- a transfer printing station is installed in a printing device, it is advantageous if the AB position and the AN position are measured. This ensures that the transfer roller always rests on the intermediate carrier with the necessary pressure.
- the AB position can be found in such a way that the drive shaft is rotated until, for example, a Hall switch arranged at the AB position responds or the eccentric bears against a mechanical stop. The first meter reading reached. the position counter can then be saved or the position counter is reset to a predetermined output value. The AB position then results from a defined difference to the first counter reading.
- the drive shaft can then move the transfer printing unit torque-controlled to the intermediate carrier until the drive shaft blocks after the transfer roller hits the intermediate carrier.
- the second counter reading of the position counter can then be saved.
- this swiveling-in process can be repeated, for example, with different intermediate carrier positions; this can also be done with continuous rotation of the intermediate carrier.
- the intermediate carrier does not have to be removed.
- An average value can then be formed from the determined second counter readings, which is used as the second counter reading in printing operation.
- a corresponding measuring process can of course also be carried out during printing breaks, for example to compensate for wear on the transfer roller or the intermediate carrier.
- the transfer unit When printing, the transfer unit is initially in the DOWN position. If printing is to be carried out, the transfer printing unit is pivoted onto the intermediate carrier until the second counter reading is reached. The pivoting process is thus position-controlled. When the second counter reading is reached, the drive unit switches over to torque control, so that the transfer roller rests on the intermediate carrier with an adjustable pressure force (via the torque). If a defined position deviation is exceeded, the torque can be adjusted in printing mode (superimposed position control). During the printing pause, the transfer printing unit is again swiveled from the intermediate carrier in a position-controlled manner until the first counter reading is reached.
- end positions of the transfer printing unit can also be determined by other means, for example a Hall switch could be arranged in each of the end positions, the sensor signal of which is evaluated.
- a Hall switch could be arranged in each of the end positions, the sensor signal of which is evaluated.
- FIG. 1 shows a side view of the drive system in the event that the transfer printing unit is pivoted (ON position);
- FIG. 2 shows a side view of the pressure system in the event that the transfer printing unit is pivoted down (AB position);
- Fig. 3 is a sectional view at K-K of Fig. 2;
- FIG. 6 shows an example of a tangential guidance of the record carrier via transfer roller and intermediate carrier with deflection rollers
- FIG. 7 shows an example of a tangential guidance of the record carrier via transfer roller and intermediate carrier with deflection jaws.
- FIG. 1 and 2 show the structure of the transfer printing station US, FIG. 1 showing the transfer printing station in the pivoted-in position (ON position), FIG. 2 in the pivoted-down position (AB position).
- the transfer printing station US serves in a known manner to transfer toner images from an intermediate carrier 3, e.g. a photoconductor drum, on a recording medium 2, e.g. a sheet of paper to reprint. Transfer printing takes place with the help of a transfer roller 1, the function of which is e.g. is described in WO 02/0777 19.
- the transfer printing station US has a drive system AS which comprises the following components: a drive unit AE, e.g. a motor with control, the drive unit AE being operable both in a position-controlled mode and in a torque-controlled mode;
- a drive unit AE e.g. a motor with control
- the drive unit AE being operable both in a position-controlled mode and in a torque-controlled mode;
- At least one compensation device 9 can be provided, expediently two compensation devices 9a, 9b.
- the drive unit AE can consist of a motor 4 with motor control (FIG. 5), on the drive shaft 11 of which the transmission element UE acts. This has an eccentric 5 and a coupling arm 6.
- the eccentric 5 is arranged on the drive shaft 11 (FIG. 3), the coupling arm 6 is rotatably and eccentrically mounted on the eccentric 5, and rotatably on the transfer printing unit UD.
- the transfer printing unit UD has the following components:
- rockers 8a, 8b in which the transfer roller 1 is mounted; the bearing rockers 8a, 8b are also rotatably arranged about the pivot bearings 12a, 12b; - possibly a deflection roller 10 for the recording medium 2 on the pressure bar 7.
- the possibly provided compensating devices 9a, 9b act between the pressure beam 7 and the rocker arms 8a, 8b in such a way that pressure is exerted on the rocker arms 8a, 8b and thus on the transfer roller 1 in the direction of the intermediate carrier 3.
- the compensation devices 9a, 9b can e.g. have a resilient or possibly damping element, as shown in FIGS. 1 to 3.
- the transfer roller 1 can thereby create parallel to the intermediate carrier 3.
- the bearing rockers 8a, 8b may move in relation to the pressure beam 7, the compensating devices 9a, 9b being tensioned or relaxed somewhat more.
- at least two compensating devices 9a, 9b are provided within the transfer printing unit UD in order to achieve a uniform pressure on the intermediate carrier 3 over the entire width of the transfer roller 1.
- the eccentric 5 is in a position which is favorable for the torque control, approximately 90 ° from the rear dead center HT (linear transmission behavior).
- the drive shaft 11 is rotated according to FIG. 2, the eccentric 5 pulls the transfer unit UD and thus the transfer roller 1 away from the intermediate carrier 3 into the AB position via the coupling arm 6.
- the transfer printing unit UD rotates around the rotary bearings 12a, 12b.
- the compensating devices 9a, 9b press the rocker arms 8a, 8b against a stop 34 on the pressure bar 7, in these phases the rocker arms 8a, 8b and the pressure bar 7 move synchronously.
- the drive unit AE has a drive shaft 11 on which the eccentric 5 is mounted.
- the coupling arm 6 is rotatably mounted both on the eccentric 5 and on the pressure bar 7.
- the bearing journals la, lb of the transfer roller 1 are mounted in the bearing rockers 8a, 8b.
- the bearings 1a, 1b (for example a ball bearing) of the transfer roller 1 in the bearing rockers 8a, 8b can accommodate an inclined position of the axis from the transfer roller 1 to the pivot bearing 12.
- the bearing rockers 8a, 8b are also mounted so as to be movable relative to the pressure beam 7 about the axis 12a, 12b.
- the transfer roller 1 can thus be adjusted in the direction of the intermediate carrier 3 by means of the compensating devices 9a, 9b so that the pressing force is equally distributed over the width of the recording carrier 3 even in the event of a wobble.
- the compensating devices 9 can damping properties Shafts have, in addition, the available compensation path is chosen so small that the drive system AS has no tendency to oscillate.
- FIG. 4 shows a basic illustration of the rotary movement of the drive shaft from the ON position to the DOWN position and vice versa.
- these end positions e.g. Hall switches H, which emit a sensor signal when e.g. a mark on the drive shaft passes the corresponding Hall switch.
- Starting from the AB position (Hall switch H2), e.g. a rotation of the drive shaft to the right until the ON position is reached, at which a Hall switch HI can be arranged.
- the transfer roller 1 Before the ON position is reached, the transfer roller 1 already touches the intermediate carrier 3 at the position BER. 4 shows the individual positions of the drive shaft with a tolerance range.
- the AB position can also be determined with a mechanical reference stop 35.
- the eccentric 5 can be in the ON position about 90 ° from a dead center HT in order to facilitate torque control.
- a transfer station US or a new transfer roller 1 is inserted into a printing device, it is expedient to adjust the rotational movement of the drive unit AE in such a way that the transfer unit UD and thus the transfer roller 1 are pivoted exactly from the AB position to the ON position and tolerances, for example in the intermediate carrier 3, the transfer roller 1 or the recording carrier 2, are compensated for.
- the AB position but especially the AN position, must be precisely defined. This can be done, for example, with the aid of a position counter, the counter reading of which indicates the position of the drive shaft 11. Then the AB position is first defined.
- the Hall switch H2 can be used, for example, which emits a sensor signal when a marking of the drive shaft 11 runs past it.
- a mechanical stop 35 at this point, which limits the rotary movement of the drive shaft 11.
- the counter reading of the position counter in this position is saved as the first counter reading.
- the AB position can, as shown in FIG. 4, be at a defined distance from the reference stop 35.
- the drive unit AE is now switched to the torque-controlled mode and the drive shaft 11 is moved until it blocks. This is the case when the transfer roller 1 rests on the intermediate carrier 3 with a corresponding pressure force. This pressure force can thus be influenced via the torque.
- the counter reading of the position counter is saved as the second counter reading.
- This second search process can be repeated several times, for example to compensate for tolerances of the intermediate carrier 3 or the transfer roller 1. An average value can then be formed from the various second counter readings, which is used in printing operation.
- the drive unit AE In print mode, starting from the AB position, the drive unit AE is initially operated in the position-controlled mode.
- the drive shaft 11 moves the transfer printing unit UD and the transfer roller 1 to the intermediate carrier 3.
- the transfer roller 1 When the position counter has reached its second counter reading, the transfer roller 1 is in the operating position for transfer printing.
- the drive unit AE is switched to the torque-controlled mode, as a result of which the transfer roller 1 rests on the intermediate carrier 3 with the desired pressing force.
- the transfer printing unit UD and the transfer roller 1 are pivoted away from the intermediate carrier 3.
- the drive unit AE is switched to the position-controlled mode and the drive shaft 11 is moved until the first counter reading is reached.
- FIG. 5 shows a construction of the drive unit AE. It has a motor 4, a motor controller 22 and a controller 26 for the recording medium 2.
- An incremental motor encoder 16 is arranged on the motor in order to perform step-by-step position monitoring with high resolution, e.g. Allow 360 ° / 8196 incremental signals.
- Lines 17 lead from this to the motor control 22, via which the incremental signals to the position counter, implemented on the motor control 22, are transmitted.
- lines 18 lead to the power supply to the motor 4.
- the motor control 22 can use a line 21 to signal a pivoting or pivoting e.g. be fed for security reasons.
- the motor controller 22 is also connected to the record carrier controller 26 via lines 23, 24 and 25.
- Line 23 is a BUS line for the transmission of parameters (e.g. torque, operating mode, error message), start / stop signals for the transfer station can be transmitted via line 24, e.g. triggering of actions such as swiveling or swiveling, via line 25 reset signal - le to put the engine control in an initial state.
- the controller 26 is supplied with sensor signals via lines 27, for example from force sensors, web tension sensors, trigger signals via line 28 and device data from device bus 30 via bus 29. Force sensors for the compensation devices
- Directions 9 position-controlled motors (eg stepper motors) can be used for the drive.
- the invention has been described in connection with a rotary drive. However, it is also possible to use a linear motor as the drive, which, however, must also be operated in the two operating modes described above. Finally, it is also possible to use two or more drive units, which can then be arranged at different locations on the transfer printing unit UD.
- the transfer roller 1 can have resilient or damping properties, e.g. by a Gunmiibe stratification, then the compensation device 9 may be dispensed with.
- the function of the transfer roller 1 is further improved if the recording medium 2 is guided tangentially on the surfaces of the transfer roller 1 and the intermediate carrier 3. This ensures that the toner transfer direction is perpendicular to the plane of the recording medium 2 and corresponds to the electric field between the intermediate medium 3 and the transfer roller 1. The result is that the toner flying is minimized and the printed image becomes more uniform.
- FIGS. 6 and 7 Two implementations of such a guidance of the recording medium result from FIGS. 6 and 7.
- the corresponding guidance of the recording medium 2 is achieved with the aid of deflection rollers 31, in FIG. 7 with the aid of deflection jaws 32.
- the tangents 33 are shown in each case , 6 and 7, the elements of the transfer printing station US according to FIGS. 1 to 3 which are not necessary for the illustration of the principle have been omitted.
