Definitions

  • the invention relates to a longitudinal cutting device for cutting current material webs, with at least one carriage which is adjustably mounted on a transversely extending to the web running direction guide and which has a holder for a freely rotatably mounted upper blade, which is deliverable in the direction of the lower blade and a drive shaft which extends over the entire width of the machine and over which the upper blade, in particular a circular blade, can be driven by means of a gear.
  • Slitting devices for paper, plastic foil and aluminum foil webs usually contain a plurality of circular knives arranged in pairs, with one pair of circular knives each severing the web for division into individual webs in the longitudinal direction.
  • Such longitudinal cutting devices are components of winding machines that produce individual narrower winding rolls from a wide material web.
  • the pairs of circular knives can be positioned transversely to the direction of web travel.
  • a generic longitudinal cutting device is known from WO 99/47317.
  • the longitudinal cutting device described herein consists of a driven upper blade and a freely rotatably mounted lower blade.
  • circular knives are used as upper knives and, in particular, pot knives are used as lower knives.
  • Each pair of knives can be positioned transversely to the running direction of the web to be divided in order to set the required format width.
  • each upper blade is adjustable in the direction of its axis of rotation against the associated lower blade, so that the two cutting edges can be aligned exactly relative to each other.
  • each upper blade can be raised to an inactive position if it is not needed for slitting.
  • a rotary drive for the upper blade is an electric motor, in particular brushless DC motors are used in a very compact design.
  • the motor is arranged above the upper blade and drives the upper blade by means of a belt. By laying the drive motor on the circular blade a narrower design of the slitter is possible.
  • a cutting device with rotary-driven knife for Fasson cut cardboard plates is disclosed.
  • the cutting edge of the cutting device consists of two separately driven circular knives, which are driven by a gear and an over the entire width of the machine extending drive shaft.
  • the carriage for receiving the circular blade is displaceable transversely to the drive shaft.
  • the circular knives are pivotally received on the axis of the driving gear, while the gears of the driving gear are in constant mesh.
  • the invention has for its object to improve a generic longitudinal cutting device so that the circular blade driving gear from the gear can be decoupled and thus each circular blade is individually switched off.
  • This object is achieved in that the angle between the line connecting the centers of a gear located on the drive shaft with a gear meshing therewith and the feed direction of the upper blade is between 60 ° and 120 ° and that a method of the circular blade by means of guide elements and against the direction of the lower blade to the decoupling of a connected with the circular blade gear and the circular blade driving gear is possible.
  • Paper, plastic, and aluminum foil web slitters typically include a series of knives arranged in pairs, with one pair of knives each severing the web longitudinally for division into individual webs.
  • Such longitudinal cutting devices are components of winding machines that produce individual narrower winding rolls from a wide material web.
  • the pairs of knives can be positioned transversely to the direction of web travel.
  • the knife pairs usually consist of an upper blade, in particular a circular blade, which is freely rotatably mounted and driven by the material web and a driven lower blade, in particular a pot knife or provided with cutting edges groove shaft.
  • the longitudinal cutting device 1 is shown with a gear transmission.
  • the longitudinal cutting device 1 consists of an upper blade 2, in particular a circular blade, a holder 3 for the circular blade 2, which is attached to a single blade holder 4.
  • the single knife holder 4 is detachably mounted on a carriage 5.
  • the carriage 5 in turn is mounted linearly displaceable on a supporting beam 6 by means of linear guide rails 7.
  • the drive shaft 8 for the circular blade 2 is rotatably mounted in a boom 9.
  • the boom 9 in turn is connected to the carriage 5.
  • the drive shaft 8 is circumferentially form-fitting, guided for transmitting torque and axially displaceable by a bushing 11, wherein the bush 11 is freely rotatably mounted on the carriage 5 and on the socket a circular blade 2 driving gear 14 is fixed.
  • the section shown in Figure 2 by the inclusion of the drive shaft 8 and through the bushing 11 and the boom 9 is used to illustrate the drive of the circular blade 2.
  • the sleeve 11 is positively, but axially displaceable on the drive shaft 8, wherein the sleeve 11 rotatably is connected to the outer ring of a bearing 12.
  • the inner ring of the bearing 12 in turn is fixed in the boom 9, so that the bushing 11 is rotatably mounted.
  • the gear 13 On the outer surface of the bush 11, the gear 13 is fixed to drive the circular blade 2.
  • the bushing 11 is axially displaceable over the longitudinal profile and / or the positive-locking elements 10 of the drive shaft 8.
  • the drive shaft 8 can be profiled, for example, be designed as a square wave or it is equipped with positive elements 10, such as sliding blocks, feather keys or ball bearings, as used for example in linear guides. It is of course also a combination of profiled and provided with positive elements 10 drive shaft 8 conceivable.
  • the torques are transmitted via the drive shaft 8 to the bush 11 and then to the gear 13.
  • the circular blade 2 is then driven by a gear 14, wherein the circular blade 2 is fixedly connected to the gear 14.
  • the material web 15 extends between the circular blade 2 and the lower blade 16, which perform a shear cut against each other be employed.
  • the cutting edge of the circular blade 2 is moved against the cutting edge of the lower blade 16.
  • the guide elements 17 can move the circular blade about 20 to 30 mm radially in the direction of the lower blade.
  • a protective cover 18 is additionally arranged.
  • FIG. 1 A preferred embodiment of the invention is shown in FIG.
  • the basic structure of the longitudinal cutting device corresponds to the embodiment described in FIG.
  • the holder 20 for the circular blade 2 is in an altered form, it also serves to receive an intermediate gear 21.
  • the drive of the intermediate gear 21 via the drive shaft 8 and the attached thereto via a bush 11 gear 22.
  • the drive shaft 8 is mounted directly on the carriage 5 in a short boom 23 rotatably.
  • the area 24 between the web 15 and the short boom 23 is free.
  • this area 24 can be further facilities for grinding or cleaning the circular blade 2 inserted or fixed. As a result, the disassembly of the circular blade 2 is facilitated.
  • coated material webs 15, such as, for example, adhesive sheets are cut with the circular blade 2, contamination may occur on the circular blade 2.
  • a device which can be arranged in the region 24 is a disk 25 made of felt. The circular disk 25 is used to clean the circular blade 2 and can be brought to the circular blade.

  • the gears 21, 22 remain continuously engaged.
  • the guide elements 17 move the holder 20 and the circular blade 2 and the intermediate gear against the lower blade 16.
  • the rotational movement of the circular blade 2 is thereby generated via a torque generated at the drive shaft 8 to the gear 22, to the intermediate -Zahnrad 21 and then transferred to the gear 14 on the circular blade.
  • the gear 14 is fixedly connected to the circular blade 2 and rotatably supported in the holder 20.
  • the advancing movement of the circular blade 2 takes place first radially in the direction of the lower blade 16 and then axially in the direction of the movement of the carriage 5 against the lower blade 16 to form a shearing system.
  • the driven circular blade 2 has the advantage that a leading cut can be produced, which has a positive effect on the quality of the cut material webs 15.
  • the disk 25 can now be moved out of felt to the circular blade 2 and clean the circular blade 2 during cutting , On the positive side, this reduces ancillary and set-up times.
  • the circular disk 25 can also clean a circular disk 2 which is not in engagement.
  • a device for grinding the circular blade can also be introduced or fixedly mounted in the free area 24.
  • a housing 26 for protecting the circular disk and for collecting dirt or abrasive particles is arranged.
