Definitions

  • the invention relates to a longitudinal cutting device for a winding machine for Winding up running material webs, in particular plastic webs, with one row of upper knives, which are designed as disk-shaped circular knives, and with a Series of lower knives, which are designed as circular knives.
  • winding machines referred to as roll cutting machines contain a slitter from which the web by slitting in Individual webs are divided, which are then wound into winding rolls.
  • winding plastic sheets it is necessary that two neighboring ones Winding rolls have a certain distance from each other so that they do not stick to interlocking a course of the webs.
  • a touch of two neighboring ones Winding rolls on their end faces must also be avoided so that Cross profile fluctuations no friction occurs between two winding rolls when these increase differently radially.
  • the winding rollers are known to be axially parallel with a distance arranged winding axes wound from each other.
  • the single tracks are alternately fed one of the two winding axes, so that two Adjacent winding rolls are wound up offset from one another. This is structurally relatively complex, since the winding machine has two winding axes got to.
  • the invention is therefore based on the object of a longitudinal cutting device to provide a winding machine with which narrow strips of Cut out less than 5 mm safely and have it removed.
  • the longitudinal cutting device has a number of upper knives 1, which as disc-shaped circular knives are designed.
  • the upper knives 1 are known Way mounted crosswise on a common axis, so that they in the desired cutting positions can be positioned. All top knives are 1 each connected to a rotary drive, for example the common axis driven.
  • the upper knife 1 are rectangular in cross section, so that they are two parallel Have side surfaces against which the cutting edge of a lower knife 2 can be employed. Each side of an upper knife 1 thus forms with one Lower knife 2 is a pair of knives that cut through the plastic web in the longitudinal direction. The two longitudinal cuts on each upper knife 1 make each one narrower Strips cut out of the web at a width equal to the width of the upper knife 1 corresponds.
  • the width of an upper knife 1 is less than 5 mm, preferably 1 mm to 2 mm to avoid the loss of web material by cutting out of the strip as low as possible with sufficient stability of the upper knife 1 hold.
  • All lower knives 2 are freely rotatable on a support shaft 3 which is fixed during operation stored. In operation, they are resilient against one side of the associated Upper knife 1 pressed and thus driven by this.
  • two upper knives 2 are assigned to each upper knife 1.
  • the lower knife 2 are also circular knives, which are designed and on the support axis 3 are mounted so that their rotating plane 4 is at an acute angle to the rotating plane 5 of the upper knife 1 runs.
  • the rotating planes 4 of two lower knives 2 assigned to an upper knife 1 are each inclined in mirror image to each other so that their cutting edges move towards and away from each other in one cycle.
  • both cutting edges contact one side of the upper knife 1.
  • the two cutting edges have the exact opposite of the upper knife 1
  • Lower knife 2 the maximum distance from each other, as in Figure 1 in each case lower position is shown.
  • pot knives are used as the bottom knife, which Have the shape of a truncated cone, the circumferential edge of the truncated cone Forms cutting edge.
  • Each lower knife 2 is on a ball bearing 7 on one Carrier bush 8 fastened freely rotatable.
  • the outer lateral surfaces of the carrier bushes 8 have the shape of a cylindrical surface, which is against the central axis 9 of the support axis 3 is inclined. So the outer race of each ball bearing 7 rotates with it attached lower knife 2 about an axis which is relative to the central axis 9 of the Support axis 3 is inclined at an acute angle.
  • the inner surface of everyone Carrier bush 8 runs parallel to the lateral surface of the support axis 3.
  • each connecting socket 10 with the two carrier bushings 8 fastened thereon fixed against rotation by means of two lateral locking pins 11, which are characterized by the extend two sockets 8, 10 and engage in an axial groove of the support shaft 3.
  • each connecting socket 10 is positioned with the ones on it fastened parts automatically in the cutting position via the lower knife 2, which are Align with the stationary upper knife 1 when placing it on it.
  • the lower knives 2 are each limited to the ball bearings 7 parallel to the central axis 9 movably mounted. Between the ball bearing 7 and the front shoulder each Lower knife 2 is a compression spring 12, of which the cutting edge in each case is pressed against the upper knife 1. The cutting edges of each lower knife 2 are thus resiliently supported on the respective upper knife 1.
  • the outer lateral surfaces of the lower knife 2 are designed so that they in the Form a cutting position parallel to the web, from which the web over their Width is supported when cutting.
  • the outer surface lines of the lower knife 2 at the point of contact on the upper knife 1 a straight line parallel to the axis of rotation of the upper knife 1 and thus in the right Angle to the side faces.
  • the support axis 3 mounted rotatable about 180 ° about its central axis 9.
  • the peripheral area of the carrier bushings 8 in the Area of the upper knife 1 moves, with the two associated lower knife 2 maximum Distance from each other.
  • the upper knife 1 can then in from above the gap 6 between the two lower knives 2 are moved.
  • the Support axis 3 rotated back into the cutting position shown in Figure 1 and in locked in this position.
  • the cutting edges of the Lower knife 2 automatically on the upper knife 1.

Abstract

Dans des enrouleuses destinées à l'enroulement de bandes en défilement, notamment des bandes plastiques, des dispositifs de coupe longitudinale sont utilisés de manière connue, lesquels possèdent une rangée de lames supérieures (1), se présentant sous la forme de lames circulaires discoïdes, et une rangée de lames inférieures (2) se présentant sous la forme de lames circulaires. Selon l'invention, une lame inférieure (2) est située respectivement de chaque côté d'une lame supérieure (1), et les lames inférieures (2) sont montées librement rotatives sur un axe porteur (3). Les plans de rotation (4) des deux lames inférieures (2) associées à une lame supérieure (1) sont mutuellement inclinés symétriquement et forment un angle aigu avec le plan de rotation (5) de la lame supérieure (1), de sorte que les arêtes de coupe des deux lames inférieures (2) se rapprochent et s'écartent lors d'une révolution. Ce dispositif de coupe longitudinale permet de découper dans la bande des bandelettes étroites et de les transporter pour ainsi pouvoir enrouler les rouleaux d'enroulement sur un axe d'enroulement commun avec l'écartement nécessaire entre eux.
