Definitions

  • the invention relates to a cutting device for data strips during machine output, the data strips generally consisting of paper, cardboard or plastic wound on rolls.
  • Such cutting devices for data strips in machine output with an electric motor drive consisting of a double-edged, helically twisted rotary knife with a spring-loaded fixed knife, e.g. according to DE-GM 84 10 627.
  • Such devices are used in automatic systems with integrated data printers for the creation and output of documents, such as Tickets, tickets, receipts, etc. Like.
  • the finished printed document is usually separated from the data medium supply roll, which is done by cutting devices.
  • a cutting device consists of a profile body in an angular shape with an outer recess for the rotary knife along an angle piece and a second angle leg as a bottom part for the motor mount at an angle between the two legs, the Profile body can be cut to the desired pass width.
  • a cover can be placed in a flattened angular shape and, on the other hand, a cover can be provided in an angular form for the drive motor, both hoods can be cut to the desired passage width according to the profile body.
  • the device consists of the two side parts 1 and 2 with an intermediate profile body 3 in an angular shape.
  • a helically twisted, double-edged rotary knife 4 is arranged in a receiving trough 3a, with which a spring-loaded fixed knife 5 interacts.
  • the profile body 3 is covered on both sides by means of hoods 6 and 7. Both the profile body 3 and the covers 6 and 7 are cut to the width of the data carrier used and then closed on both sides with the side parts 1 and 2.
  • Threaded bores 37 are provided on both sides of the profile body 3, the side part 1 being fastened on one side by means of a screw 38, which side accommodates a changeover switch 8, a feeler lever 9, a control line 10 and a bearing 11.
  • the side part 2 is attached, which receives an electric motor 12 with a multi-stage gear 13 and a bearing 14 is fastened to the threaded bore 37 by means of screw 45.
  • the profile body 3 there is also a longitudinal groove 39 for inserting nuts 40 which are used to fasten the cutting device, e.g. serve on data printers.
  • the coiled, double-edged rotary knife 4 made from a section steel has two stub axles 15 and 16 formed on it.
  • the rotary knife forms the two cutting edges 17 and 18 which run helically to the central axis 19 of the profile.
  • One stub axle 15 receives a thrust ring 20 and a two-notch control disk 21, while a gear wheel 22 is placed on the other stub axle 16.
  • the ends of the stub axles 15 and 16 then serve to mount the rotary knife 4 in the bearings 11 and 14 of the side parts 1 and 2.
  • the sprung fixed knife 5 is also from one Piece of profile bar is formed and has bearing bolts 23 and 24 inserted on both end faces, the bearing bolt 24 having a slot 25 for hanging a helical torsion spring 26.
  • the bearing pin 23 is received by an eccentric 27 arranged in the side part 1. Appropriate eccentric adjustment ensures that the cutting edge 28 of the fixed knife 5 extends obliquely to the central axis 19 of the double-edged rotary knife 4, so that the distance between the cutting edge 28 and the central axis 19 of the rotary knife 4 is greater on the side of the thrust ring 20 than on the opposite side, to get an overflowing cutting process.
  • the second bearing pin 24 of the fixed knife 5 provided with a slot 25 is received by the side part 2.
  • the cover 6 envelops the rotary knife 4 received by the receiving trough 3a of the angle profile 3 as well as the fixed knife 5 as protection against the risk of injury and forms one with the profile body 3 on the one hand, an inlet shaft 33 and, on the other hand, an outlet column 34 for the cut piece of data carrier.
  • the cover 7 is to be snapped onto the profile support 3 and forms with this and the two side parts 1 and 2 a tightly closed chamber for the electric motor 12 with gear 13 and changeover switch 8 against dirt and dust, inter alia from the cutting chamber and against contact. If the electric motor 12 is now put into operation with the aid of a start pulse, then it rotates the double-edged rotary knife 4 via the multi-stage gear 13 and the toothed wheel 22, so that its cutting edge 17 moves towards the cutting edge 28 of the spring-loaded fixed knife 5. At the same time, the pushbutton 9 is pressed out of the notch 35 of the control disk 21, which in turn actuates the changeover switch 8. A suitable circuit then applies voltage to the electric motor 12.
  • the data carrier to be separated is located between the cutting edge 17 of the double-edged rotary knife 4 and the cutting edge 28 of the spring-loaded fixed knife 5 and is separated when the double-edged rotary knife 4 is continuously rotated.
  • the cutting process begins when the cutting edge 17 of the double-edged rotary knife 4 has reached the cutting edge 28 of the spring-loaded fixed knife 5 and ends when the double-edged rotary knife has rotated further, namely by angle " ⁇ ".
  • the second notch 36 of the control disk 21 triggers the switchover of the changeover switch 8 into its starting position via the feeler lever 9, so that the power supply to the electric motor 12 is interrupted and the latter comes to a standstill.
  • the double-edged rotary knife 4 has made half a revolution and, since the two cutting edges 17 and 18 are arranged symmetrically, has the same starting position as before.
  • the second cutting edge 18 of the double-edged rotary knife 4 comes into effect, the double-edged rotary knife 4 being rotated again by half a turn.
  • the alternating use of two cutting edges 17 and 18 is of particular advantage in two respects; On the one hand, the service life of the rotary knife is practically doubled, and on the other hand, the expiry time per cutting process, with the same motor and gear design, is halved.
