Definitions

  • the invention relates to a tachograph for a motor vehicle with a receptacle for a roll of paper, with a printing unit for outputting data in exactly intended positions on a visible grid of a paper strip wound on the paper roll, with a drive device for driving the paper strip of the paper roll and with an electronic Control device for controlling the printing unit and the drive device. Furthermore, the invention relates to a paper roll for such a tachograph with a arranged on a wound paper strip and to be printed area, with a visible grid on the area to be printed.
  • Known writing devices generally have a spiked roller whose spikes penetrate into edge perforations of the paper strip and ensure the advance of the paper strip of the paper roll under the printing unit.
  • An edge perforation of the paper strip is used to align the printing unit relative to the area to be printed with the grid and reduces the slip when driving the paper strip.
  • the printing unit is adjusted relative to the area to be printed on a reference position. The adjustment is to ensure that the data, for example a graphic representation of the driving speed of the motor vehicle, is transmitted over time in the intended positions on the visible grid.
  • a disadvantage of the known tachograph and the known paper roll that tolerances between the printing unit and the visible grid of the area to be printed on the paper roll can occur, so that the position the data on the visible grid is not reliably guaranteed.
  • Such tolerances may be in the components of the tachograph itself, for example, by variations in the diameter of the spiked roller or the position of the printing unit.
  • tolerances can arise due to geometrical fluctuations of the paper dimensions or the optically visible grid.
  • tolerances can also be caused by moisture absorption of the paper strip of the paper roll during operation of the tachograph.
  • the invention is based on the problem to design a tachograph of the type mentioned so that a reliable transmission of the data is guaranteed to the intended positions of the printable area with the visible grid. Furthermore, a roll of paper for such a tachograph should be created, which ensures a reliable assignment of the transmitted data to the visible grid.
  • the first problem is inventively solved in that at least one sensor is connected to the control device that the sensor for detecting arranged on the paper strip of the paper roll markers and the control device for controlling the position of the printing unit on the paper strip of the paper roll in response to the signals of the sensor is formed.
  • the position of the paper strip of the paper roll is detected and then controlled the position of the printing unit and the drive means of the paper roll.
  • the tachograph according to the invention can therefore be operated particularly comfortable.
  • the sensor can continuously align the position of the printing unit to the paper strip and thus to the visible grid of the paper roll. This ensures that the data is reliably transferred to the intended position of the area to be printed with the visible grid.
  • the sensor should be arranged as close as possible to the printing unit.
  • Lateral variations in the guidance of the paper strip can be easily detected according to another advantageous embodiment of the invention, when the first, for detecting the longitudinal direction of the movement of the paper strip of the paper roll sensor has a longitudinally extending on the paper roll, a guideline scanning sensor line.
  • the proposed speed of transport of the paper is reliably detected according to another advantageous embodiment of the invention, when the second, designed to detect the movement of the paper strip sensor has a periodically repeating on the paper roll markings scannable sensor element.
  • the tachograph invention structurally designed particularly simple when the sensors are designed to detect optical, magnetic, inductive or electrical markings.
  • a limitation of the freedom of movement of the printing unit over the area to be printed by the sensors can be determined according to another advantageous embodiment of the invention simply avoid when the sensors are arranged on a side opposite the printing unit side of a paper guide. As a result, one side of the paper strip is available exclusively for the output of the data, while the other side can have the markings for the sensors.
  • the second mentioned problem namely the creation of a paper roll for such a tachograph, which ensures a reliable assignment of the transmitted data to the visible grid, according to the invention is achieved by the fact that intended for scanning by sensors of the tachograph markings in a designated position to the visible grid of the area to be printed are arranged.
  • markings are arranged on the paper strip of the paper roll, which allow an accurate alignment of the area to be printed with the visible grid to the printhead of the tachograph. Therefore, the data transmitted from the tachograph can be reliably assigned to the visible grid.
  • a disturbance of the transmitted data by the markings can be easily avoided according to an advantageous development of the invention, when the markings are arranged on the back of the area to be printed.
  • the markings in the longitudinal direction of the paper are particularly simple according to another advantageous development of the invention, if the markings have a guideline extending in the longitudinal direction of the paper strip.
  • An intended drive of the paper strip by the tachograph can be easily arranged in accordance with another advantageous embodiment of the invention in the tachograph Detecting sensors when the markers are repeated periodically.
  • the paper roll according to the invention makes it possible to subdivide into a plurality of individual areas to be printed by a plurality of individual, separate, visible grid networks and end markers associated with the beginning and / or the end.
  • the markings are structurally particularly simple if the markings are optically, magnetically, inductively or electrically palpable.
  • a near end of the paper roll can be seen according to another advantageous embodiment of the invention without affecting the area to be printed when extending on the back of the area to be printed at the end of the paper roll, preferably over 10 to 12% of the total length of the paper strip of the paper roll , visible color marking is arranged.
  • Figure 1 shows schematically a tachograph 1 for a motor vehicle with a front panel 2 in a longitudinal section.
  • the tachograph 1 has a magazine 3 with a paper roll 4 and a motor drive device 5 for transporting a paper strip 6 wound on the paper roll 4. Furthermore, the tachograph 1 has a printing unit 7 for printing the paper strip 6 of the paper roll 4. To simplify the drawing of the printing unit 7, only a pressure roller is shown.
  • the paper strip 6 of the paper roll 4 is guided from the magazine 3 in a paper guide 8 on the printing unit 7 to a gap 9 in the front panel 2. Through the gap 9 in the front panel 2 of the printed 7 printed paper strip 6 is output and can be demolished.
  • two sensors 10, 11 for detecting the position of the paper strip 6 in the paper guide 8 are arranged on the paper guide 8.
  • the sensors 10, 11, the motor drive device 5 and the printing unit 7 are connected to an electronic control device 12.
  • the control device 12 controls the printing unit 7 and the drive device 5 in response to the signals of the sensors 10, 11.
  • the position of the printing unit 7 is aligned with the position of the paper strip 6.
  • FIG. 2 shows a partial region of the paper strip 6 of the paper roll 4 from FIG. 1 with an area 13 to be printed by the printing unit 7.
  • the area 13 to be printed has a visible grid 14 formed as a grid and two scales 15, 16.
  • One of the scales 15 extends in the longitudinal direction of the paper strip 6 and may, for example, represent the time axis, while the other of the scales 16 is arranged transversely to the longitudinal direction of the paper strip 6 and characterizes the travel speed of the motor vehicle.
  • FIG. 3 shows a rear side of the paper strip 6 from FIG. 2 and schematically the sensors 10, 11 of the tachograph from FIG. 1.
  • Markings 17, 18 which are detected by the sensors 10, 11 are arranged on the rear side of the paper strip 6 become.
  • One of the markings 17 is designed as a guideline arranged centrally on the paper strip 6, while the other markings 18 are repeated periodically.
  • the paper strip 6 has different end markings 19, 20, which are assigned to the region 13 to be printed on the front side shown in FIG.
  • One of the sensors 11 has a sensor line 21 which extends transversely to the longitudinal direction of the paper strip 6 and scans the marking 17 formed as a guideline.
  • the other of the sensors 11 has a single sensor element 22 for scanning the periodically recurring marks 18 and the end marks 19, 20.
