Definitions

  • the invention as defined in claim 1 relates to a document shredder, in particular a so-called office shredder, with an attachment for receiving and feeding documents, in particular crumpled material, e.g. in paper baskets and similar containers collected crumpled paper.
  • Shredders are known in practice, which can also be used for shredding so-called crumb material.
  • these document shredders In addition to a feed gap for sheet-like material, these document shredders have a material collecting container mounted on top of the housing upper part for receiving crumb material.
  • these document shredders usually have a cabinet-like or cabinet-like base on which the upper housing part is arranged together with the attached material collection container.
  • document shredders of this type are known from DE-A-2 335 344 and GB-A-2 095 579, which can optionally be operated with an attachment for receiving and feeding in particular wrinkled documents, as obtained in wastebaskets.
  • the object of the invention is therefore to design a document shredder, in particular a so-called office shredder so that, while maintaining the existing office shredder security regulations, a speedy shredding of the filled into the essay, the cutting unit supplied crumb is secured, in particular essential business interruptions by accumulated material be avoided.
  • the invention relates to a document shredder with an attachment for receiving and feeding documents, the shredder a housing, which consists of a lower housing part and a housing upper part, and a arranged in the upper region of the housing cutter, with cutting rollers and scrapers together with an associated Drive unit and switching and control means, and wherein above the cutting mechanism in the front region of the upper housing part, a feed gap is provided and the lower housing part contains or receives means for collecting the comminuted material.
  • the upper surface of the housing upper part has an optionally removable and reusable housing portion part, and that starting from the cutting mechanism to the open upper surface sufficiently a feed chute is provided, and that the open area of the top surface is covered by an attached to the upper housing part essay, the lower surface is opened substantially and in particular in said overlay region, wherein the interior of the article and the feed chute form a common receiving space, and that integrated in the essay a non-rotating material slide is arranged.
  • the new essay for a shredder which receives said so-called crumpled paper and feeds the cutting unit, is designed such that on the one hand inadvertent intervention by hand, through the receiving space of the essay through, can not be done in the current cutting mechanism, on the other hand in the receiving space of the essay and / or in the cutting unit upstream feed chute jammed, currently not moving crumb material is loosened for further slipping towards the cutting and at the same time or immediately afterwards - or in advance - towards the cutting unit pushed towards, while running cutting.
  • This too is one significant advantage of the subject invention over known solutions.
  • the material slide consists of two laterally arranged in the essay legs, which are connected to the front surface by a bar, which is arranged aligned substantially parallel to the axes of rotation of the cutting rollers with each other.
  • the material slider is mounted translationally displaceable. According to another embodiment, however, the material slider may be pivotally mounted. Which version is chosen depends on the mainly intended use; with large-volume crumpled paper, the pivoting material slider is more likely to be used, but ultimately it is a decision of the user.
  • the legs of the material slide arranged displaceably guided in or on the side surfaces of the attachment or the legs with their other Ends are each attached to a rotary bearing, wherein the latter is associated with an actuating shaft, which preferably protrudes from the side surface of the attachment and can be actuated substantially from there.
  • the material slider is preferably made as a one-piece bracket.
  • the provided in the upper housing part feed chute is formed by side walls, a front boundary surface and a front towards the cutting unit inclined rear boundary surface, the rear boundary surface ends at a small distance in front of the outer peripheral line of the rear cutting roller and the imaginary extension of the substantially planar rear boundary surface substantially tangentially engages the rear cutting roller on its outer circumferential line, and the rear boundary surface is at the same time the lower stop for the movement of the material slider.
  • the imaginary extension of the movement path on which the middle part of the displaceable material slider, in particular the strip, is moved extends essentially through the overlapping region of the cutting rollers.
  • Another embodiment provides that the boundary surface of the feed gap and the front boundary surface of the feed chute are a common component.
  • FIGS. 1 and 2 show only partially in section to better illustrate the invention.
  • 1 shows a portion of a shredder 1.
  • a cutting unit 6 with cutting rollers 6a and 6b and associated scrapers 6c is arranged in the upper area, wherein the cutting unit 6 is assigned a drive unit 5.
  • the cutting unit 6 is here essentially covered by a housing upper part 4 placed on top of the housing lower part 2 from above.
  • a feed gap 7 with boundary surfaces 7a and 7b is arranged, through which sheet-like material for comminution can be fed to the cutting unit.
  • a feed chute 8 is provided up to the upper surface 4b of the upper housing part 4, the forward by a front boundary surface 9 and to the rear by a rear, to the cutting unit 6 inclined towards boundary surface 10 and not shown in this figure lateral walls 25 and 26, see Fig. 2, is limited.
  • an attachment 11 is placed on the upper housing part 4, wherein in the covered area, the upper surface 4b of the upper housing part 4 is opened by removing a housing section, not shown, to the interior of the essay.
  • a lower surface 16 of the attached attachment 11 is also substantially open, so that in the interior of the article 11 poured, so-called crumpling of the formed with the boundary walls 13, 14, 15, 24 and 9, 10, 25, 26 common receiving space from deliberately slip to the cutting unit 6 and can be cut by the same in strips or particles.
  • the said rear boundary surface 10 of the feed chute 8 starting from the upper edge of the upper housing part 4, starting inclined to the cutting unit. Depending on the size of the ball of Knüllmateriales but it may still come to interrupt the supply of the crumb to the cutting unit.
  • this embodiment of the invention provides in particular that in the interior of the article 11, a material slide 17 is arranged, which by pressing, coming from above said crimping material in Direction of the material feed-in gap 6d of the cutting unit 6 pushes and, if necessary, presses against at least one of the cutting rollers 6a, 6b, so that selbige entrains the crumpled material in the direction of material intake gap 6d.
