Definitions

  • the invention relates to a device for aligning a sheet according to the Preamble of claim 1.
  • Devices are, for example, but not exclusively, in function of front marks or side marks for aligning sheets of printing material, especially paper sheets, before printing in a sheet-fed printing machine used. Alignment of the individual sheets is required because the sheets of a stack, for example using a flaking device and be promoted. The alignment of the individual sheets after removal from the Stacking is usually not enough to produce sufficient print quality.
  • the deviation of the individual sheets to be aligned from the required Target orientation varies within certain after removing from a stack Limits.
  • To reliably handle both smaller and larger deviations To be able to align the interaction of the stop element with the drive element, it is required in the known devices that the drive element the bow promotes against the stop element over a certain distance.
  • This maximum Feed determines the maximum correctable position error.
  • an undesirable Bulging of the paper during the feed movement of the drive element after the To prevent the bow from attaching to the stop element must be known Devices can be guaranteed that a slip between the drive element and the bow is possible. For this purpose, the pressure with which the drive element engages on the elbow comes, be networked.
  • the pressure should be chosen at least so large that the Stiction between the drive element and the sheet during the feed is sufficient to reliably move the actuating element to the arc transfer.
  • the pressure is selected to be at most so high that the Friction between the drive element and the bow after the stop Side edge of the sheet on the stop element from static friction in sliding friction transforms. In other words, it means that the pressure is between two borders must be chosen, by which it is ensured that the sheet up to the stop on Stop element is advanced together with the drive element, and after Stop the bow on the stop element, the drive element over the Bow surface slides.
  • a disadvantage of the known devices and the known The process for aligning sheets is to choose the necessary proof between bend and drive element of the material type of the bend used depends. Therefore, especially when using paper materials a change of material, the setting of the pressure depending on the processing paper type can be found again.
  • DE 196 12 542 A1 and DE 196 12 545 A1 describe devices for Aligning sheets using intermittent impulses.
  • the post-published DE 101 02 227 A1 shows a device for aligning Sheet using piezo actuators and sensors, but without side marks.
  • DE 198 22 307 A1 discloses a position of a side edge of a sheet relative to detect a stop using a light barrier.
  • the invention has for its object a device for safe, creating a low-damage alignment of an arch.
  • the advantages that can be achieved with the invention are, in particular, that the bow not in one continuous feed motion against that Stop element is promoted, but several, especially a variety of Drive phases are cycled through, in which the arc in smaller Feed movements in the direction of the stop element is promoted.
  • the Rest phases between the individual drive phases are no driving force from Transfer the drive element to the sheet so that the feed movement of the sheet is slowed down or brought to a standstill in the resting phases.
  • the Feed movement during each drive phase is chosen to be relatively small can be deduced from the fact that the maximum arching of the arch caused by the Feeding the arc during a drive phase is relatively low and so it's not critical.
  • the maximum bulge caused by a drive phase can be done by reducing the feed amount during each Drive phase can be reduced as desired.
  • a sensor is provided with which the system the side edge of the sheet to be aligned can be detected on the stop element can. As soon as the sensor emits a corresponding signal, it can Drive element are switched off so that the bend no further in the direction of Stop elements are promoted.
  • the arch after contact on Stop element only a few times or not at all in the direction of Stop element is further promoted.
  • the arch will only extend as far bulge out as it does through the feed during the final drive phases in which the Stop element still comes to rest on the arch, is conditional. Since the feed in each individual drive phase is relatively small, the bulge overall be limited below permissible tolerances.
  • the drive element is disengaged in the rest phases.
  • the feed amount during a drive phase can then be just as large or small can be chosen so that after the sheet is in contact with the stop element during the bulging of the arch occurring during individual drive phases for the duration of one the subsequent rest phase disappears completely. For example the drive element is lifted off the arch during the resting phases, so that the bow is no longer clamped between the stop element and drive element.
  • the drive element If the drive element is lifted off the arch during the rest phases, it is special advantageous if it is in according to the feed amount during the drive phases the rest phases are moved in the opposite direction. As a result, it goes through Drive element during each cycle, which consists of a drive phase and a resting phase, a certain closed trajectory. By Cyclic traversing of this path of movement can in principle be arbitrary be promoted far against the stop element without the drive element itself even closer to the stop element than its path of movement.
  • the arc can then be used with several Drive elements promoted in one direction or in different directions and be aligned.
  • the drive phases of the various drive elements do not essentially overlap. This can be achieved that the arc is always in one by only one of the drive elements certain direction is promoted and this alignment movement is not promoted by others, also with the arc engaging drive elements is hindered.
  • the arc When aligning the arcs, the arc is iteratively approximated to the Stop element several cycles, each consisting of a drive phase and one Rest phase, go through.
  • the alignment quality can in particular thereby be increased so that the feed movement is possible during the individual cycles is small and as high as possible during the available alignment time Number of cycles.
  • the highest possible repetition frequency of the individual cycles is therefore desirable, but with increasing frequency also an increased design effort is required because the inertia forces with Increase the movement frequency disproportionately.
  • the frequency range from 500 Hz to 15,000 Hz has been proven. In particular one Repetition frequency of around 5,000 Hz is a good compromise Alignment quality and required construction effort.
  • the amount of feed by which the arc through the drive element during a individual drive phase is promoted in the direction of the stop element decisive influence on the alignment result. It can be done by reducing the The iterative alignment movement always during each cycle be further refined. It is particularly advantageous if the feed amount during a drive phase in the range of 0.1 ⁇ m to 10 ⁇ m is selected. In particular a A value of approximately 1 ⁇ m during a cycle has been found to be a suitable feed amount proved.
  • each stands for the alignment individual sheets have a maximum alignment time of 0.18 seconds.
  • Repetition frequency selected a frequency of 5,000 Hz and is the feed amount during a drive phase and thus the maximum contact error during a Drive phase 1 ⁇ m, this results in a maximum feed amount over which the Sheet can be funded during the available alignment time by 0.9 mm.
  • the arch would therefore pass in 5,000 individual steps within 0.18 seconds 1 ⁇ m are approximated to the stop element.
  • this can Drive element with cyclically changing feed speeds iteratively the stop element are approximated, the system of the bow on Stop element can be detected with a sensor, so that the drive element after Stop on the stop element can be switched off. Because the drive element after Apply the bow to the stop element by evaluating the sensor signal can be switched off, can disengage the drive element during the Rest periods are waived. Excessive bulging of the arch after the The system is attached to the stop element by monitoring using the sensor locked out.
  • the drive element can be designed such that it, for example can be disengaged by lifting from the bow.
  • Monitoring the attack of the bow on the stop element by means of a sensor can in this case are provided, but is not mandatory. Because by the possibility Disengaging the drive element can cause the bow to become idle due to gravity and its inherent tension against the bulging back deform. That means the bulging caused by one drive phase each disappears again in the subsequent rest phase, in which the drive element is not engaged with the bow.
  • a sensor for monitoring the stop of the bow can be provided on the stop element.
  • the drive element can be in the rest phases corresponding to the feed amount in the drive phases in the opposite direction to Feed the sheet so that during each cycle, consisting of drive phase and rest phase, a closed movement path passes.
  • the shape of the movement path can be chosen arbitrarily. For example, trajectories that are rectangular are conceivable. Especially short cycle times can be achieved if the trajectory of the Drive elements of an essentially ellipsoidal path in a vertical plane equivalent.
  • a sensor can be provided with which the stop one Side edge of the sheet is detectable on the stop element.
  • the sensor is in the manner of an electrical or an electronic Evaluation device is designed with which the electric current for driving the Drive elements when feeding the sheet in the direction of the stop element is evaluable. Because with the stop of the side edge of the sheet on the stop element the current increases significantly during the feed of the drive element, so that this feature can be evaluated for the detection of the sheet stop.

  • a microphone as a sensor for detecting the Bow stop is used. With the stop of the bow on the stop element a certain acoustic signal connected that by means of a suitable microphone can be recorded and evaluated.
  • a suitable one must of course be used to drive the drive element Drive arrangement can be provided with an actuator.
  • Particularly suitable for this are piezo actuators because these actuating movements with very high frequencies enable.
  • the drive element To achieve sufficient static friction between the drive element and the bow it is necessary for the drive element to interact with a counterholder, so that the arc between the drive element and the counter holder can be clamped.
