Definitions

  • the invention relates to a storage device for a pre-folded continuous paper web in a paper stacker.
  • a pre-folded continuous paper web has folded edges at a certain, uniform distance, which is called the form length. If such an endless paper web is fed to a paper stacker, for example after it has been printed in a high-speed printer, it is placed in a zigzag position on a storage surface.
  • a number of faults can occur when depositing the continuous paper web. If the continuous paper web is fed to the paper stacker from a high-speed printer, for example, it is stretched and the fold previously applied is smoothed. As a result, it can happen that the paper web is not deposited cleanly in layers, but instead lies on the storage surface in an unordered manner. A similar effect can occur if air cushions form under the individual layers when they are set down, which direct the subsequent sheet of the continuous paper web in the wrong direction.
  • An impact of a sheet on a form length adjusting device delimiting the paper stack can also cause the continuous paper web to overshoot. This overshoot can lead to undulating increases in the sheet deposited and this in turn interferes with the stacking process.
  • Another common cause of such disturbances is that the folded edges of the folded and stacked paper do not attach to the paper stack. nestle and this swells upward in a disorderly fashion near the fold.
  • DE-OS 26 34 300 describes a paper depositing device as prior art, in which two blowers are provided, through which air is blown onto the two folded edges of the paper stack. This pushes the two fold edges of the top sheet of the paper stack down. However, the effect is not yet completely satisfactory.
  • the invention was based on the object of specifying a storage device for trouble-free stacking of a pre-folded continuous paper web in a paper stacker.
  • This object is achieved by at least one air outlet nozzle and by a direction control device for the air flow of the air outlet nozzle.
  • the control device makes it possible to direct the air flow precisely onto the area of the sheet to be deposited, where air cushions are most effectively displaced and the sheet is best pressed down.
  • the air flow can also serve to bring the continuous paper web into the effective range of these means. There is also an optimal direction of the air flow for this.
  • a filing device in which papers of different form lengths are deposited, this represents a considerable improvement. If one directs an air flow in the vicinity of the folded edges of the top sheet, a point can be found at which the air flow has an optimal effect. If an endless paper web of a different form length is deposited with this setting, the air flow no longer hits the area in which an optimal effect is achieved. Faults in the storage of the continuous paper web can therefore occur again.
  • the advantage of the filing device is therefore that an optimal direction of the air flow can be set for each form length.
  • Another solution to the problem is to provide at least one air outlet nozzle and an intensity control device for the air flow in a storage device for a prefolded continuous paper web in a paper stacker.
  • the behavior of a continuous paper web in a storage device depends to a large extent both on the form length, as well as on the inherent rigidity and the weight of the paper.
  • the intensity of the air flow which displaces air cushions and which should press the paper to be deposited onto the top sheet of the paper stack, must be matched to the properties of the paper. Paper with high inherent rigidity requires a higher intensity of the air flow than light, flexible paper. An intensity of the airflow that prevails for strong paper partial, can prove to be too strong with light and flexible paper.
  • the invention offers the possibility of setting the optimal intensity of the air flow for each type of paper. It thus has the advantage of reducing the susceptibility to faults in filing devices in which different types of paper are stacked.
  • a coupling device is provided between the form length adjusting device on the one hand and the direction control device and / or the intensity control device on the other hand, the coupling device depending on the Position of the form length adjusting device acts on the control of the direction control device and / or the intensity control device.
  • a lateral stop of the paper stack that can be changed depending on the form length can serve as the form length adjusting device. If a form length setting device is present in a filing device, this must be changed in each case if a continuous paper web with a form length other than the set form is to be stored.
  • the advantage of the coupling device is that no additional work is required to achieve the effect according to the invention, since the position of the form length adjusting device is changed anyway and independently of the invention.
