Definitions

  • the invention relates to a device for cutting sheet-like Good, especially in the form of stacks, with a support frame, a positively driven and simultaneous lateral movement Knives movable up and down, two in different Angled linear guides for one knife receiving knife carrier and drive means for moving the knife carrier.
  • a device of the type mentioned is basically out known from DE 42 06 338 A1.
  • the knife holder is linear driven cutting device associated with linear guides on which one or more linear roller units connected to the machine frame roll. These linear roller units are pivotable in the Support frame stored.
  • the swivel bearing is therefore outside the linear guide with the consequence of a rather large lever arm, of the introduction of high bending moments in the support frame when Conditional on cut.
  • the swivel bearing is and dimension the linear guide accordingly, which is associated with a high construction and cost, also a considerable one additional mass must be moved during the cut.
  • a device of the type mentioned is also from DE 44 40 754 C1 known.
  • the linear guides are on the support frame side arranged guide rails formed, on which form-fitting Carriages run, which are articulated via pins with the knife carrier are connected.
  • An axial needle bearing surrounds the respective pin.
  • a further axial bearing is provided for the nut screwed on.
  • the knife carrier is thus stored in the journal and not, as with the first-mentioned prior art, in the supporting frame; nevertheless due to the design of the linear guides with the outside the linear guides arranged and the distance the bearing point of the cutter bar from the linear guide too this device has the same disadvantages as the State of the art mentioned at the beginning.
  • DE 196 29 285 C1 discloses a device of the type mentioned kind known, in which a roller bearing also in a carriage Linear guide a pin for the pivotable mounting of the Knife holder is provided. There is the pivot axis of the pin arranged at a distance from the guide axis of the linear guide and it fastening elements are provided parallel to the pivot axis, which connected the knife carrier to the carriage. These fasteners enforce recesses in the knife with radial play.
  • This device also has the disadvantages mentioned above on.
  • a first solution to the problem according to the invention provides for a device of the type mentioned above that the respective linear guide an outer pair of guide rails, which with the support frame is connected, and an inner, in the outer pair of rails positively guided Has guide rail, wherein, the respective linear guide assigned a bearing element is connected to the knife carrier, the is mounted axially and radially in the inner guide rail.
  • the bearing element is pivotable in the inner guide rail is mounted. This allows the resulting Force application point of the bearing element as tight as desired the cutting plane. Preferably the resulting one Force application point of the bearing element selected so that it at least approximately coincides with the cutting plane. It arises so that when cutting, a clearly directed, but in amount small bending moment that from the respective bearing element into the inner Guide rail is initiated.
  • Storage is preferably carried out of the bearing element in the inner guide rail and the storage the inner guide rail in the outer pair of guide rails essentially in one plane. The cutting forces are thus without noteworthy bending moments, from the knife / knife holder to the respective one Bearing element in the inner guide rail and from there into the outer pair of guide rails. Because of the invention Design and arrangement of the aforementioned components can not Expansion of the storage area and therefore no undefined Game of parts moving relative to each other.
  • the respective linear guide has an outer pair of guide rails, which is connected to the support frame, as well as an inner, in the outer Rail pair has positively guided guide rail, wherein, the respective Assigned linear guide, with the knife carrier a bearing element is connected, which is mounted within the linear guide.
  • the respective bearing element used to support the knife carrier is preferably designed as a bolt or pin.
  • a special Embodiment of the invention provides in this context that the bearing element is firmly connected to the knife carrier.
  • the firm Connection can be achieved, for example, in that the bearing element, specifically the bolt, screwed to the knife holder is.
  • the guide rail is expediently made by means of two divided Axial / radial bearings that are inserted into the inner guide rail and are clamped when screwing the bolt into the cutter bar become.
  • the arranged in the long, outer pair of guide rails shorter inner guide rail has a relatively large length, at least half the length of the outer pair of guide rails equivalent.
  • the inner guide rail therefore does not function of a carriage, but requires tilt-free guidance.
  • the respective guide rail of the outer pair of guide rails essentially one M-shaped cross section and that of the respective outer guide rail facing section of the inner guide rail one in has a substantial V-shaped cross section.
  • the inner guide rail in the outer pair of guide rails is roller-supported.
  • the storage of the inner guide rail in the outer pair of guide rails can for example by means of a cage guided between them respectively.
  • the cage is preferably V-shaped in cross section educated. It can be designed as an angle flat cage, which holds a large number of rolling elements.
  • the storage of the inner guide rail according to the invention in the outer pair of guide rails according to the present Invention by using a flat cage guide HYDRL / EGIS M and V guide rails with integrated rack for Positive guidance of an angular needle roller flat cage with a pinion according to the catalog of HYDRL AG / INA LINERTZ technology OHG, part number 005-276-373 / FRF-D-D-049915, pages 62 to 64 his.
  • the knife holder can be operated in different ways be one-sided or two-sided. With two-sided Attacking a power tool on the knife carrier can, since no high Forces to be passed through the knife holder, the knife holder and the linear guides assigned to it have smaller dimensions become.
  • the respective power means is, for example around a hydraulic cylinder or an electromotive Drive using a crank drive.
  • the cutting machine according to the invention is shown in FIGS. 1 and 2 shown schematically. It has a stand 1, a back table 2 for receiving the material to be cut and a front table 3 to pick up the cut material. With the one to be cut For example, it is a large format Stack made up of a large number of sheets of paper one on top of the other is.
  • the rear table 2 is in the rear area by means of Supports 4 supports.
  • stand 1 there are 2 and 3 above tables a press beam 5 for fixing the material to be cut before Cut, and in front of the press bar 5 a knife 6 to cut of the material to be cut.
  • the storage of the knife 6 takes place in the Stand 1 indirectly, that is, it is the knife 6 with a knife holder 7 screwed, which is movably mounted in the stand 1.
  • the vertical to the support surface 8 of the tables 2 and 3 Section plane is illustrated by means of the dash-dotted line 9.
