Definitions

  • the invention relates to a numbering device in which changes in the numbering wheel position are monitored and a method for monitoring the change in position of numbering wheels.
  • Numbering devices have long been used, in particular, to print individual alphanumeric character combinations on documents, for example the serial numbers of banknotes, securities or checks.
  • sheet or web printing presses are used in the majority of cases, which are equipped with a large number of such numbering devices, so that a large number of character combinations are printed on the base in a first step and then the individual objects with the corresponding one in a second step
  • Serial numbers - usually fully automated - can be separated, stacked and packed.
  • An example of such numbering methods is, for example EP 1 389 524 A1 refer to.
  • a numbering device which comprises a numbering wheel driven by a motor and an optical sensor for detecting the position of the numbering wheel.
  • the optical sensor in turn comprises a photo detector, which works together with an encoder disc, in which the position of the numbers on the numbering wheel is coded by holes or fixed sections.
  • the sensor provides a binary signal that is the number that is in the print position when the print wheel is in this position. The signal is then compared with a signal representing the target position of the numbering wheel and the motor is operated until the sensor signal and the position signal match.
  • the object on which the invention is based is therefore to provide an improved numbering device with improved position monitoring and a method for improved position monitoring of the numbering wheels of a numbering device which, particularly in the case of small and compact numbering units, reliably provide position information.
  • the numbering device according to the invention has numbering wheels arranged next to one another on an axis, which, if they are set to a printing position, can be used for printing symbols, for example alphanumeric symbols or other characters.
  • the printing positions are the positions at which pressing the numbering device onto the substrate to be printed results in a symbol arranged on the numbering wheel or a blank location for the correct printing of the corresponding symbol aligned with the adjacent numbering wheels.
  • At least one of the numbering wheels of the numbering device is driven by a motor, numbering wheels driven by motors having at least one magnetic, optical or inductive marking and the numbering device having at least one sensor for detecting magnetic, optical or inductive markings.
  • all numbering wheels are designed in this way.
  • At least one motor has an encoder for monitoring the motor movement and that the numbering device has monitoring electronics which is in signal communication with the at least one sensor and the encoder of the at least one motor, the monitoring electronics having a memory in which at least one Encoder position at which a magnetic, optical or inductive marking of a numbering wheel would have to be detected by the sensor during proper operation are stored and where the monitoring electronics are also set up so that they check whether the magnetic, optical or inductive marking of the corresponding numbering wheel has been detected by the sensor when an encoder position stored in the memory for a numbering wheel is reached or exceeded. This check is possible, for example, using a processor in the monitoring electronics, in particular if it is executing a corresponding program.
  • standing in signal communication means that at least signals from the encoder or sensor can be read by the monitoring electronics, with intermediate processing of the signals, e.g. through an edge detector circuit.
  • This measure gives the possibility, at least for position changes, in which a marking would have to pass the sensor, which is possible because of the storage of the encoder positions, at which a given marking is arranged, in the memory, to check directly whether a motor given control command was actually executed.
  • the encoder or the monitoring electronics or a signal path between the encoder and monitoring electronics has an incremental encoder with a counter, since this simplifies the identification of the positions.
  • the magnetic marking can be made very simple and can be realized, for example, by one or more small bar magnets which are inserted radially into the numbering wheel with a predetermined orientation of the poles.
  • magnetic, optical or inductive markings of numbering wheels driven by motors are each arranged between two adjacent printing positions. With this configuration it is achieved that the magnetic, optical or inductive marking has to pass completely through the sensor during the movement between these two printing positions. This makes an evaluation of the sensor signal using the correlation to the encoder signal easier and more precise, since the difficult proof of a maximum is eliminated and instead one can focus on the detection of a rising and a falling signal edge, which then also provides precise information about the encoder values, e.g. the steps for an encoder with incremental encoder and pedometer, in which the magnetic, optical or inductive marking passes the sensor, are permitted.
  • At least one magnetic, optical or inductive marking is arranged at all printing positions and / or between all printing positions of numbering wheels driven by motors, the advantageous effect is achieved that every movement of the numbering wheel between printing positions must bring with it a magnetic signal, so that through the Correlation data stored in the memory can be verified immediately for each movement command for a numbering wheel whether a movement has also taken place.
  • the numbering wheel has twelve printing positions and / or if one of the printing positions of the numbering wheel is a blank printing position, that is to say a printing position in which a printing operation with the set number on the numbering wheel moved to the blank printing position does not leave an imprint on the assigned digit of the number. It is also particularly preferred if all magnetic, optical or inductive markings are identical except for one magnetic, optical or inductive marking.
  • the correlation between encoder data and sensor data which is achieved by the invention, can be used to identify the respectively set printing position, i.e.
  • a magnetic, optical or inductive marking deviating from all other magnetic, optical or inductive markings is expediently provided, which in the case of magnetic markings can consist, for example, of an oppositely polarized magnet, a plurality of magnets, a stronger magnet or the absence of a magnet . It is particularly preferred if all magnetic, optical or inductive markings are identical except for the magnetic, optical or inductive marking of the blank position.
  • the correlation between encoder data and sensor data can be determined particularly precisely if the monitoring electronics are set up in such a way that they check whether the signal from the Sensor has a rising and a falling edge. In view of possible influences of the fields of magnetic markings of adjacent numbering wheels, this can be important for successful operation of the monitoring electronics and the reliable correlation of encoder position and magnetic field sensor data with one another. It is particularly preferred if the target positions of rising and falling edges of magnetic, optical or inductive markings are stored in the memory.
  • the correlation data is determined using a reference run, in which the numbering wheels, which are driven by motors, are run at least one full revolution and the encoder position values, at which the signal from the sensor indicates the passage of a magnetic one , optical or inductive marking indicates to be saved.
  • the determined correlation data can be further stabilized if several reference runs are carried out to determine the correlation data or if a reference run comprising several revolutions of the numbering wheels, which are driven by motors, is carried out, the respectively stored encoder position values of the individual revolutions being statistically evaluated.
  • Such a statistical evaluation can in particular also contribute to the fact that tolerance-related fluctuations in the position, which are statistically distributed, can be distinguished from actual malfunctions and corresponding threshold values or tolerance thresholds are known, so that false fault reports are avoided.
  • the method is further improved if at least one teach run is carried out, in which a numbering wheel driven by a motor is brought into a defined printing position by hand or by mechanical pre-positioning with a positioning lever or a pawl and the encoder steps until a predetermined magnetic level is reached , optical or inductive marking can be determined.
  • a numbering wheel driven by a motor is brought into a defined printing position by hand or by mechanical pre-positioning with a positioning lever or a pawl and the encoder steps until a predetermined magnetic level is reached , optical or inductive marking can be determined.

  • the motors 109, 110 are preferably designed as stepper motors or brushless DC motors.
  • Figure 2 shows an example of a drive train 120 constructed according to the invention, including its electronic components for a numbering wheel 108 of such a numbering device 100.
  • An encoder 121 is arranged on the motor 109 with a gear 111 connected upstream, which encoder can be designed, for example, as a magnetic disk and by means of which the movement of the Figure 1 visible motor axis 114 can be monitored.
  • a sensor 130 is provided for each numbering wheel 108 driven by a motor, which can be designed, for example, as a Hall sensor, while on the numbering wheel 108 - in this exemplary embodiment, between its printing positions 115, on which the alphanumeric symbols are arranged, so that the Press the numbering device onto the one to be printed
  • a printing position 115 a symbol arranged on the numbering wheel 108 or a blank location for proper printing of the corresponding symbol aligned with the adjacent numbering wheels 108 are arranged - markings 131, which in this exemplary embodiment are designed as magnets.
  • Monitoring electronics 140 are also provided. The monitoring electronics 140 are in signal communication both with the encoder 121 and with the sensor 130, the latter taking place via an intermediate edge detection circuit 132.
  • the monitoring electronics 140 have a processor 141 and a memory 142, to which the processor 141 has both write and read access.
  • the processor can execute programs that can be stored, in particular, in a memory (not shown) that is provided internally in the processor or externally.
  • the processor 141 is still in signal communication with a counter 143, which can increase and decrease its counter reading in response to signals from the encoder 121, but the counter reading can also be set by the processor 141.
  • the counter 143 can also be designed as a separate component that is not assigned to the monitoring electronics 140 or can be implemented as a component of the encoder 121. It is advantageous if the counter 143 is designed cyclically, which means that there is a highest counter reading, when the counter is exceeded, the counter starts counting again. In this way, if the highest counter reading corresponds to the number of encoder pulses required for a complete revolution of a numbering wheel 108, it can easily be achieved that the same printing positions 115 must always occur at the same counter reading. However, this can also be done achieve that a modulo operation is used in the evaluation of a continuous counter 143.
  • a single monitoring electronics 140 which is equipped with a sufficient memory 142 and a single processor 141 when it is in signal communication with all encoders 121 and all sensors 130, is sufficient for the operation according to the invention of a numbering device with several numbering wheels driven by motors is.
  • the memory 142 can also be integrated in the processor 141.
  • monitoring electronics 140 need not necessarily be designed as separate electronics, but can be designed as a component of the control electronics that control the movement of the numbering wheels 108 by the motors 109, 110.
  • the processor 141 of the monitoring electronics 140 checks whether the correct correlation exists between the signals of the encoder 121, which can be evaluated in particular as counter readings of the counter 143, and the sensor 130. For this purpose, e.g. those counter readings of the counter 143 are stored in which, in the normal operation of the numbering device 100, the edges of sensor signals which are to be expected when passing markings between adjacent printing positions 115 of the respective numbering wheel. These counter readings can be derived analytically from the geometrical arrangement of the markings 131, since, given the system translation, it is known how many encoder steps there are between printing positions; you can also teach them in in a test run.
  • the processor 141 can then be triggered, for example, by a signal from the edge detection circuit 132, for example by a signal from the edge of the sensor 130 Interrupt, are caused to compare the current counter position, which the counter 143 displays, with the target counter position stored in the memory 142. If the comparison shows a match, this is a sign that the movements of the motor 109 detected by the encoder have actually caused the associated numbering wheel 108 to move. If, however, there is a deviation, there is an error.
  • the comparison can also be implemented by continuously monitoring the counter reading of the counter 143 and by analyzing the signal of the sensor 130 from the processor 141 at the target counter positions stored in the memory 142 to determine whether or not it detects the expected marking. If this is not the case, there is an error.
  • an error analysis and possibly an error correction can optionally be carried out with the system according to the invention.
  • a control command or a step of the motor 109, 110 has not been translated into a corresponding rotation of a numbering wheel 108, the expected signal must be verified accordingly later.
  • the difference in the counter reading of the counter 143, at which the signal is detected, can be determined by the processor 141, which then causes an additional movement command to be given to the motor 109, 110 and / or either before the next printing process Resets counter status of counter 143 accordingly or corrects the target counter positions of counter 143 stored in memory 142 accordingly.
  • FIGS each show examples of the arrangement of magnetic markings, which are identified by the letters “N” or “S”, on a numbering wheel 108 with 12 printing positions 115 each and a driving gear 116 arranged on the numbering wheel 108.
  • Ten printing positions bear the numbers 0 to 9
  • a block printing position is also provided, which enables the printing of a block, but could also be provided with another symbol, for example an asterisk, and a blank printing position is provided which prints an empty space.
  • a magnetic north pole N is provided in the middle between the blank printing position and the number 0 and successive numbers 1 to 9, which can be realized, for example, by a small bar magnet with its north pole facing outwards at this position in the numbering wheel, which is then preferably made of non-magnetic material, is let in.

  • Two magnets with north poles N are arranged next to one another between the number 0 and the number 1, so that a wider signal from a magnetic field sensor monitoring the magnetic markings occurs during this change in position.
  • a magnetic north pole N is provided in the middle between the successive numbers 0 to 9 and between the number 9 and the block position, and between the block position and the blank position, while between the blank position and the position the number 0 a magnetic south pole S is provided, so that a wider signal from a magnetic field sensor monitoring the magnetic markings occurs during this change in position.

  • the encoder values of the encoder 121 are shown in the line below the signal from the sensor 130. In the present case, two given printing positions 115 are separated from one another by 20 encoder steps.
