Definitions
- the invention relates to a device for monitoring the transport of a band-shaped carrier in a printing device.
- a latent image is often generated by means of an electrographic method on a belt-shaped toner image carrier, to which toner is subsequently attached.
- the toner image carrier is often designed as a self-contained belt that runs over rollers and is driven by a drive roller.
- the latent image can e.g. by exposing a photoconductor or by magnetizing a magnetically sensitive layer.
- the toner image is then transferred from the carrier to a recording medium, e.g. Paper, reprinted and later affixed to it.
- a form places high demands on the accuracy with which the toner images have to be positioned on the recording medium during the transfer printing.
- a form has so-called form windows m which certain information is to be reprinted.
- the corresponding toner image for example, must not extend beyond the window, rather it should be reprinted as centered as possible m the window.
- multi-color printing in which several toner images of different Faroe are successively overprinted in order to produce a multi-color image, it is important for a good printing result that the individual toner images can be positioned with high accuracy during transfer printing.
- a printing device is known from EP 0523870, in which several partial images of different colors are successively generated on a ribbon-shaped toner image carrier.
- the individual partial images are each at a defined distance from one another and are re-printed at the same time when a recording medium is repeatedly passed past a transfer location. So that an uneven rotational movement of the individual rollers on which the toner image carrier runs does not lead to a deterioration in the printing result due to a non-congruent transfer printing of the partial images, all of the rollers have the same diameter in each case such that the distance between two successive partial images is equal to the circumference of a roller or a multiple of it. Periodic changes in transport speed therefore have the same effect on all drawing files.
- slippage between the drive roller and the toner image carrier means that the individual toner images are no longer printed exactly in the corresponding form window. This worsens the pressure offense and should be avoided if possible.
- US 5096044 describes a device in which the transport of a band-shaped carrier is monitored. For this purpose, the dwell time of a wedge-shaped mark on the carrier in the detection range of a sensor is determined and compared with a target value, which is determined as a function of the signal from another sensor, which corresponds to the speed of the drive roller for the carrier.
- the transport of the carrier is interrupted if the length of stay exceeds or falls below a limit.
- US-A-5, 300, 983 shows a device in which a wedge-shaped mark is printed on the carrier and the dwell time in the detection range of a sensor is determined.
- the dwell time changes, it cannot be distinguished either whether the wearer's track or its transport speed has changed.
- JP-08-076 546 a device which has a first pulse train for the wearer and a second im-
- REPLACEMENT BLA ⁇ (RULE 26) pulse train generated for its drive roller.
- the device measures the time between a pulse of the first pulse train and the subsequent pulse of the second pulse train. The maximum permissible value of this time for a good printing result depends on the transport speed of the carrier.
- JP-05-11525 shows a similar device in which the number of pulses in a pulse train for a drive motor is determined between two pulses in a pulse train for the wearer. With this device, the maximum number of pulses allowed for a good printing result also depends on the transport speed of the carrier.
- JP-05-281807 also shows a device with a mark on a band-shaped carrier.
- the number of pulses in a pulse train for a drive roller is measured during one revolution of the mark and compared with a desired value determined without slippage.
- it cannot be differentiated here whether a deviation from the target value is caused by a change in slip or by a change in length of the band-shaped carrier.
- the maximum permissible deviation from the target value for a good printing result in this known device also depends on the transport speed of the carrier.
- REPLACEMENT BLA ⁇ (RULE 26 ßig slip between the drive roller and the photoconductor belt, however, there is increased wear.
- a device for monitoring the transport of a band-shaped carrier m of a printing device in which a drive roller drives a band-shaped carrier by frictional engagement on its periphery, the rotational movement of the drive roller is mapped by a first sensor m a first electrical pulse sequence, the forward movement of the carrier is imaged by a second sensor in a second electrical pulse sequence, the time interval between two pulses of the respective pulse sequence corresponds to a certain angle of rotation or path traveled, a control device the ratio of the time intervals of the first pulse sequence and the second pulse sequence determined, and in which depending on this ratio acts on the printing operation.
- the angle of rotation of the drive roller or the distance traveled by the carrier is known, which corresponds to two successive pulses of the pulse sequence in question, and the radius of the drive roller is also fixed. Therefore, the control unit can easily determine the circumferential speed of the drive roller and the speed of the carrier from the respective pulse sequence.
- the slip of the carrier against the drive roller can then be determined directly from the ratio of the time intervals of the two pulse sequences and controlled as a function of the ratio be influenced on the printing operation. If the slip exceeds a limit value, the printing operation can be interrupted, for example. It is also possible to control the rotational speed of the drive roller as a function of the behavior of the time intervals between the two pulse sequences in such a way that the carrier is moved forward at a constant, predetermined transport speed.
- the slip is set to a minimum value during a measuring process.
- the control device records the second electrical pulse sequence as a reference during the calibration. The determination of the slip in printing operation can thereby be determined particularly easily from the relative change in the time intervals of the second pulse sequence.
- the controller preferably determines the slip from the ratio of the time intervals of the pulse sequences. Such a direct slip measurement enables the printing operation to be controlled at an early stage, even before the toner images are positioned so imprecisely that rejects are produced.
- the first or the second sensor generates at least one electrical pulse with each revolution of the drive roller or with each revolution of the carrier.
- slip measurements can be carried out at least once per revolution or revolution. This means that not only very slow slip movements can be monitored.
- One embodiment of the invention is characterized in that at least one mark is arranged on the carrier, the second sensor detecting the passing of the mark and generating an electrical pulse when it is detected.
- This embodiment is technically easy to implement. sieren.
- the mark can be, for example, a simple slot in the carrier or a mirror plate attached to it.
- a transmitted light sensor or a reflected light sensor can then be used as the sensor.
- the mark is generated by an image generation unit on the carrier.
- This brand can e.g. be positioned close to the toner image.
- This mark can then be used to obtain direct information about the slip that occurred when this toning image was printed over.
- the mark can also serve to position the toner image more precisely.
- Such a mark produced on the carrier enables the use of a device according to the invention even with a non-closed band-shaped carrier.
- At least one pulse train can also be generated by a clock disk. Then the slip can be determined simply by paying out the pulses without the need for an additional time measurement.
- At least two marks are arranged on the carrier.
- a drive is provided for the drive roller and the marks are spaced from one another such that the drive is again in the same position when the carrier has moved forward by a distance corresponding to the distance between the marks.
- All individual elements of the drive and also the drive roller itself are made out of round, or have slightly eccentric axes.

- a ref. 1 reflecting plate 14 is arranged on the carrier 10, and a magnetic plate 16 is fastened in an outer region of the anti-friction roller 12.
- a magnetic sensor 18 is arranged as the first sensor near the peripheral surface of the drive roller 12 and is connected to a control device 22 via a signal line 20.
- a reflected light sensor 24 is arranged as a second sensor near the outer circumferential surface of the band-shaped carrier 10. The reflected light sensor 24 is also connected to the control device 22 via a signal line 26.
- the magnetic plate 16 rotates at an angular speed of the drive roller 12 corresponding to the peripheral speed V w .
- the magnetic sensor 18 detects the passing of the magnetic plate 16, generating an electrical pulse each time it passes, which is transmitted from the signal line 20 to the control device 22.
- the reflecting plate 14 rotates at the speed V B of the carrier 10, and its passing the reflected light sensor 24 is detected by the latter.
- the electrical pulse generated by the reflected light sensor 24 is transmitted from the signal line 26 to the control device 22.
- FIG. 2 shows two pulse sequences which were each generated by the sensors 18, 24 of the exemplary embodiment from FIG. 1.
- a first pulse sequence generated by the magnetic sensor 18 is shown at the top in FIG. 2, which represents the rotary movement of the drive roller 12.
- Time t is plotted on the abscissa and voltage V is plotted on the ordinate.
- the magnetic sensor 18 generates the Passing the magnetic disk 16 each time an electrical pulse.
- Two successive pulses of the first pulse sequence have the time interval T w , which is related to the peripheral speed V w of the drive roller 12 m of the relationship B1 shown in FIG. Where d is the diameter of the drive roller 12.
- a second electrical pulse sequence is shown, with which the forward movement of the carrier 10 is depicted.
- Time t is again plotted on the abscissa and voltage V is plotted on the ordinate.
- V is plotted on the ordinate.
- the time interval T B fulfills the relationship B2 m FIG. 4, where V H is the speed and L E is the length of the carrier 10.
- FIG. 3 shows a process sequence for determining the slip between the drive roller 12 and the carrier 10.
- the process is started in process step S10.
- step S12 parameters for the slip determination can be entered.
- the diameter d of the drive roller 12 and the number N of the repeated determination of the slip for the purpose of subsequently forming the mean value are entered into the control device 22 in a method step S12 using a keyboard.
- step S14 it is checked in method step S14 whether the drive roller 12 and the carrier 10 are already in a steady state, ie it is determined whether the peripheral speed V w of the drive roller 12 is constant. For this purpose, two successive time intervals T w of the first pulse sequence are compared with one another. As long as the peripheral speed V w is not is currently recognized, the system branches back and step S14 is carried out again.
- step S16 follows.
- the slip S is determined from the time intervals T w , T B of the first and the second pulse sequence according to the relationship B3 m FIG.
- B3, 1 is the circumference of the drive roller 12 and L B is the length of the carrier 10.
- the slip S is determined consecutively in accordance with the number n entered several times in method step S12 and the mean value is formed from the individual results. This can reduce the influence of periodic speed fluctuations, for example if the drive roller 12 is not completely round.
- the process is then ended in step S18.
- the slip in method step S16 can also be determined in another way.
- the drive roller 12 and the carrier 10 m are brought into a state in which there is practically no slippage. This can be done by reducing the band load of the band-shaped carrier. In this state, the time interval between two successive pulses of the second pulse sequence is determined and stored as a reference value T B o.
- the slip S is then calculated according to the relationship B4 in FIG. 4. If the slip S is determined in this way, the magnetic plate 16, the magnetic sensor 18 and the signal line 20 are not required and can accordingly be omitted.
- FIG. 5 shows a further exemplary embodiment of the invention.
- the drive roller 12 has a belt wheel 28 with 72 teeth.
- the pulley 28 is over a Timing belt 30 with 90 teeth connected to a pulley 32 of a stepping motor, the pulley 32 having 18 teeth.
- a second reflective plate 34 is attached to the outer peripheral surface of the carrier 10.
- the drive roller 12, the belt wheels 28, 32 and also the toothed belt 30 generally have manufacturing defects. That is, the drive roller 12 and the belt wheels 28, 32 are not ideally round or their respective axes of rotation are not perfectly centered, and the toothed belt 30 has a different thickness along its circumference. All of this leads to so-called runout errors, i.e. periodic synchronism fluctuations. If one determines the slip S from the time intervals T B of the pulses which are generated by the reflection light sensor 24 as the plates 14, 34 pass by, these periodic synchronous fluctuations lead to errors in the determination of the slip S.
- the distance between the two reflecting plates 14, 34 is selected such that in a state without slipping, the belt wheel 12 and thus the drive roller 28 has rotated five times about its own axis when the carrier 10 rotates from the position shown into one Has moved position in which the second plate 34 is detected by the reflected light sensor 24. Up to this point the toothed belt 30 has made four revolutions and the belt wheel 32 twenty revolutions. This corresponds to the smallest common multiple of the number of teeth.

- the slip S can be calculated according to the relationship B4 in FIG.
- the drive roller 12, the belt pulleys 28, 32 and the toothed belt 30 each have essentially integral numbers of revolutions, the periodic runout errors in each case cannot influence the result determined for the slip S. Even if the slippage causes the drive roller 12, the pulleys 28, 32 and the toothed belt 30 to have turned slightly after the time T B , the influence of this error on the value for the slippage S determined according to the method described above is comparative - wise little. A statistical evaluation with multiple determination of the slip S and subsequent averaging can thereby be avoided.
