Definitions

  • the invention relates to a device for separating and reapplying an incoming material web on winding machines to a winding tube, which is driven to rotate via a shaft, the incoming material web being pressed against the winding tube by means of a deflection roller partially wrapped by the material web, and wherein the outgoing material web follows Leaving the winding tube is separated by means of a separating knife which is movable in the path of the material web and can be driven by an energy store and extends transversely to the web path, and the new web beginning is applied to the winding tube using a brush.
  • a device of the aforementioned generic type is known from DE-OS 24 18 409.
  • a deflecting roller is pressed against the web between the empty winding tube and the full roll in the running web by means of a swivel frame so that the web loops around the empty winding tube by more than half the circumference, whereupon by a toothed on the axis of the deflection roller pivoted Cutting knife, which is driven by a torsion bar, the material web is separated.
  • the separating knife carries a brush on the side facing away from the deflection roller, which brushes the web against the empty winding tube when the separating knife pivots.
  • DE-OS 22 32 336 describes a device for separating and reattaching a material web to a winding tube, with a separating element which is driven by a pneumatic or hydraulic drive via a toothed rack and a toothed segment, the running web between an empty winding tube and a Deflecting element separates, the separating element being pivoted coaxially to the winding tube and then an air box connected to the separating element pressing the start of the web against the winding tube.
  • contact systems which work with separating devices which cut on the winding tube and require special winding tubes with cutting grooves on the core.
  • core damage occurs over time due to the cutting process, which together with the grooves in the core cause deformations in the material web in the winding.
  • the invention was therefore based on the object of providing a device of the generic type mentioned at the outset which enables both a reliable severing of a running web of material and the application of the new beginning of the web to the winding tube even at high speeds, with a good cut quality and a crease-free application of the Are ensured at the beginning of the web on the winding tube.
  • the course of the path can be seen from FIGS. 1 and 2.
  • the material web (1) tapering in the direction of the arrow is brought up to the winding tube (2) by means of a swiveling deflection roller (5) over which it runs with its underside. pressed, wrapping a part of the circumference of the winding tube with its top.
  • the winding tube (2) is drivably mounted on the shaft (11).
  • the running material web (1 ') is fed to a winding roller (not shown) and wound on it until the full winding diameter is reached.
  • the device for separating and reattaching an incoming material web consists of a separating knife (3) which extends transversely to the path of the web and which is fastened to guide bands (6, 6 ') on both sides.
  • These belts can be a circulating chain or a belt, a rope or the like.
  • the circulating belts are guided over rollers or sprockets (4, 4 '), which must be freely running and easy to move and which are located in the area of the winding tube (2) outside the core tensioning device.
  • the entire device for separating and reapplying (3, 4, 4 ', 6, 6', 7) can be designed with two arms, as can be seen from FIG. 1, the two arms (15, 15 ', 16, 16') on both sides Connected to one another via joints (14, 14 ') and designed to be pivotable by means of displaceable cylinder guides (13, 13'), so that the entire separating device can be temporarily pivoted away for the purpose of turning the winding device.
  • the separation and re-application process of the material web proceeds as follows. After the full winding circumference on the winding tube has been reached, the separating device is prepared for the separating process by driving a flywheel (8) via an axis by means of the electric motor (17). 4 ') set in accelerated rotation and the cutting knife (3) onto the cutting point via the guide belts (12) which is located directly next to the circumference of the winding tube (2) in the region of the running material web (1 '). When the cutting knife (3) hits the material web (1 '), the speed of the cutting knife must be greater than the running speed of the film web.
  • the separating knife overtakes the newly formed start of the web, and the painting brush (7), which is directed radially onto the circumference of the empty tube (2), strokes the beginning of the web on the winding tube.
  • the cutting device (3) is braked again via the guide belts and the guide rollers and returned to the rest position (10), which is also the starting position. Then the full web winding can be removed from the turret winder, whereupon an empty winding tube is put in its place.
  • the separation and application device described is completely pivoted away.
  • a pressure roller (18) is pivoted onto the circumference of the winding tube (2) to be rewound, while the deflection roller (5) is pivoted away.
  • the turret winder By swiveling the turret winder through 90 ° to 180 °, depending on the number of winding cores, the positions of the winding cores are interchanged.
  • the pressure roller (18) remains pivoted on the newly created roll.
  • the separating and applying device is returned to its working position. Shortly before the new winding has reached the desired diameter, the material web is pressed against the empty winding tube (2) by the deflection roller (5) and the separating and applying device is started by the motor (17). The cutting and changing process can start again.
  • the separating knife (3) with the contact brush (7) is passed very close to the circumference of the winding tube (2) so that a good cut quality is achieved and at the same time the newly formed start of the web is securely attached to the winding tube.
  • the design of the separating device, with which the separating knife is guided over belts, makes it possible to achieve the desired separating speed by sufficient length of the acceleration path, which can still be achieved even at high running speeds of the material web.
  • the acceleration path of the cutting knife is preferably approximately the same length as the braking path.
