Definitions

  • the invention relates to a longitudinal cutting device for cutting running material webs, with at least one slide which is adjustably mounted on a guide extending transversely to the web running direction and which has a holder for a freely rotatable upper knife, which can be set in the direction of the lower knife, and a drive shaft, which extends over the entire width of the machine and over which the upper knife, in particular a circular knife, can be driven by means of a gear.
  • Longitudinal cutting devices for paper, plastic film and aluminum foil webs usually contain a plurality of circular knives arranged in pairs, with a pair of circular knives each cutting the web in the longitudinal direction for division into individual webs.
  • Longitudinal cutting devices of this type are components of winding machines which produce individual, narrower winding rolls from a wide material web. In order to be able to produce different winding roll formats, the pairs of circular knives can be positioned transversely to the web running direction.
  • a generic longitudinal cutting device is known from WO 99/47317.
  • the longitudinal cutting device described here consists of a driven upper knife and a freely rotatable lower knife.
  • circular knives are used as the upper knife and pot knives in particular as the lower knife.
  • Each pair of knives can be positioned transversely to the running direction of the web to be divided to set the required format width.
  • each upper knife can be adjusted in the direction of its axis of rotation against the associated lower knife, so that the two cutting edges can be aligned exactly relative to one another.
  • each upper knife can be raised to an inactive position if it is not required for slitting.
  • An electric motor serves as the rotary drive for the upper knife, with brushless DC motors in particular being used in a very compact design. The motor is located above the upper knife and drives the upper knife by means of a belt. By laying the drive motor over the circular knife, a narrower design of the longitudinal cutting device is possible.
  • US Pat. No. 3,974,727 discloses a cutting device with a rotary knife for cutting cardboard sheets.
  • the cutting edge of the cutting device consists of two separately driven circular knives that are driven by a gear and a drive shaft that extends over the entire width of the machine.
  • the slide for receiving the circular knife can be displaced transversely to the drive shaft.
  • the circular knives are pivotally received about the axis of the driving gear, the gears of the driving gear being in constant engagement.
  • the invention has for its object to improve a generic longitudinal cutting device according to Patent No. 101 47731 so that the circular knife driving gear can be decoupled from the gearbox and thus each circular knife can be switched off individually.
  • This object is achieved in that the angle between the connecting line of the center line of the center points of a gearwheel located on the drive shaft with a gearwheel engaged with it and the feed direction of the upper knife is between 60 ° and 120 °.
  • FIG. 1 shows the basic structure of a longitudinal cutting device with a gear drive for driving the circular knife
  • FIG. 2 shows a section through the drive shaft and the gear transmission according to FIG. 1 in section INI
  • FIG. 3 shows the basic structure of a longitudinal cutting device with a gear drive for driving the circular knife
  • Longitudinal cutting devices for paper, plastic film and aluminum foil webs usually contain a number of knives arranged in pairs, each pair of knives severing the web in the longitudinal direction for division into individual webs.
  • Longitudinal cutting devices of this type are components of winding machines which produce individual, narrower winding rolls from a wide material web.
  • the knife pairs can be positioned transversely to the web running direction.
  • the knife pairs usually consist of an upper knife, in particular a circular knife, which is freely rotatably mounted and driven by the material web, and a driven lower knife, in particular a pot knife or a grooved shaft provided with cutting edges.
  • the longitudinal cutting device 1 is shown with a gear transmission.
  • the longitudinal cutting device 1 consists of an upper knife 2, in particular a circular knife, a holder 3 for the circular knife 2, which is attached to a single knife holder 4.
  • the individual knife holder 4 is releasably attached to a carriage 5.
  • the carriage 5 is in turn mounted linearly displaceably on a support beam 6 by means of linear guide rails 7.
  • the drive shaft 8 for the circular knife 2 is rotatably mounted in a boom 9.
  • the boom 9 is in turn connected to the carriage 5.
  • the drive shaft 8 is circumferentially form-fitting, for transmitting a torque and axially displaceably guided through a bushing 11, the bushing 11 being fastened to the carriage 5 in a freely rotatable manner and a gearwheel 14 driving the circular knife 2 being fastened to the bushing.
  • the section shown in Figure 2 through the receptacle of the drive shaft 8 and through the bushing 11 and the bracket 9 serves to illustrate the drive of the circular knife 2.
  • the bushing 11 is positively but axially displaceably arranged on the drive shaft 8, the bushing 11 being rotationally fixed is connected to the outer ring of a bearing 12.
  • the inner ring of the bearing 2 is in turn fastened in the arm 9 so that the bushing 11 is rotatably mounted.
  • the gear 13 for driving the circular knife 2 is fixed.
  • the bushing 11 is axially displaceable over the longitudinal profile and / or the form-fitting elements 10 of the drive shaft 8.
  • Drive shaft 8 can be profiled, for example designed as a square shaft, or it is equipped with form-fitting elements 10, such as slot nuts, feather keys or ball guides, as are used, for example, in linear guides.
  • form-fitting elements 10 such as slot nuts, feather keys or ball guides, as are used, for example, in linear guides.
  • a combination of profiled drive shaft 8 and provided with form-fitting elements 10 is of course also conceivable.
