Definitions

  • the invention relates to a cutting and winding device for film strips, in which, following a slitting station for cutting film strips from a web, the film strips arranged essentially in a horizontal row are guided to a winding or winding unit. It also relates to a method for changing the spool or winding core when winding up the film strips.
  • a continuous film web of constant width is cut into individual film strips. This is done with the help of a row of stationary separating knives arranged perpendicular to the web running direction, which are equally spaced from one another and protrude into the web with their cutting edges directed against the web movement.
  • the finished film strips are then individually wound onto spools or flangeless winding cores on a winding unit.
  • the individual winding units can be arranged in a row one behind the other or next to one another in the running direction of the film strips, or if there are a large number of film strips to be wound up, several rows of winding units can also be arranged one above the other in tiers.
  • DE 34 14 636 describes a method for changing bobbins, in which the amount of waste which is to be reduced when winding up several rows of winding units which are arranged one behind the other.
  • a cutting and winding device is known, in which the separate film strips are wound onto cores which are firmly connected to a winding shaft, and four winding shafts are present within a winding star, which are axially displaceable and one denaturing and one Assembly device can be supplied, which simultaneously takes care of the removal of one winding shaft from winding cores and the loading of another shaft with new winding cores.
  • a reel cutting and winding machine for film strips is known, in which, following a longitudinal cutting station for cutting web strips from a web, a separation station is provided for separating adjacent web strips into separate winding axes, with alignment combs in the longitudinal grooves of each winding axis radial alignment edges are adjustably arranged, which position the winding tubes.
  • a corresponding device is known in which, following a slitting station for cutting strips of film from a web, the films on individual Winding cores are guided and each winding core is assigned a drive roller resting on the circumference of the winding.
  • winding devices for cut web strips are known, in which the strips are guided over a so-called spreading comb, which are pins which deflect the film strips in different directions and the strips are wound up with a device according to DE 23 65 606 mentioned above.
  • this requires extensive effort when changing the bobbin as soon as the full winding circumference is reached.
  • a 65 cm wide magnetic tape web is cut lengthways into 3.81 mm wide strips, which are wound on winding cores, around 170 tape windings have to be glued at the end and removed from the winding axis, after which these winding axes are newly fitted with cores, on which then the beginnings of the film strips must be attached.
  • This can mean a considerable changeover time, which is about as long as the winding time.
  • a further work step arises from the fact that the finished tape rolls may have to be provided with intermediate layers for transport and stacked on top of each other in larger containers.
  • the device described above takes up a considerable amount of space. Therefore, the task was to find a winding device of the generic type mentioned above, which - is compact - Significantly reduced changeover times when changing the winding - already delivers ready-to-ship packages.
  • Figure 1 shows schematically the side view of a preferred embodiment of the device according to the invention.
  • the film web (1) coming from a casting or extrusion device (not shown) is fed in the direction of the arrow via a cross cutting device (2) to be described further below, and subsequently via a loop puller (8) to compensate for the web voltage fluctuations.
  • the web is subsequently cut lengthwise into narrow strips (4) by means of a separating knife arrangement (9), the axis of which is arranged perpendicular to the direction of the film web, or a reel cutter.
  • a separating knife arrangement 9
  • Such arrangements are known from numerous publications, for example from DE 24 05 849 or DE 37 01 716 from the applicant, where in particular arrangements for cutting magnetic tape webs in film strips are described.
  • the cut strips are passed between a pivotable pressure roller (6), the width of which is at least as large as the entire width of the film web, and a guide suction comb (3).
  • the suction comb consists (FIG. 2) of a number of vertically arranged segments (5), the number and width of which corresponds to the number and width of the film strips and which can be subjected to negative pressure. The segments are spaced from each other. The suction comb is laterally pivotable in the film running direction.
  • the winding of the film strips (4) is accomplished by a rotatable winding device (10) consisting of at least two arms (12, 12 '), at the free ends of which a drivable shaft (13, 13') is located as the winding axis.
  • a rotatable winding device consisting of at least two arms (12, 12 '), at the free ends of which a drivable shaft (13, 13') is located as the winding axis.
  • flange coils or flangeless winding cores 14, 14 '
  • Flange-less winding cores and particularly preferably stackable winding cores according to DE 24 48 853 are preferred for winding according to the device according to the invention, which are stacked on top of one another so that they are tensioned on a winding shaft in such a way that the windings or the winding surfaces lie practically spaced apart.
  • the cross-cutting device (2) already mentioned is used to produce a defined strip length, one strip length being provided with the following one with a specific adhesive point.
  • this device consists in a preferred embodiment of a three-part cutting table. This has two fixed parallel support rails (16, 17) transverse to the film running direction and a narrow movable support rail (18) arranged between them. Between the two columns of the rails (16, 17) and the vertically displaceable rail (18), two cutting wheels (15, 15 ') or cutting knife blades for cross-cutting the web (1) can be immersed.
  • adhesive tape (22) for connecting the two separate web pieces a tape provided with an adhesive surface is preferably used, the two lateral ends (19, 19 ') of which are turned away from the adhesive surface (20), are bent at an obtuse angle and are free of adhesive (FIG. 4).
  • the cutting table can consist of only two support rails, with one there between the gap, a rail being horizontally displaced after the separation of the web by the width of the rail (18) and the adhesive connection subsequently being produced.
  • the adhesive tape (22) can also have only one glue-free, bent end.
  • the full tape windings (23) wound on the winding cores (14) are each with an adhesive tape (22) on the outer circumference of the tape winding.
  • the roller (6) is then pivoted onto the suction comb (3), the segments (5) of which are subjected to negative pressure, so that they suck in the film strips (4).
  • the rotatable roller (6) is wetted on its cylindrical surface (24) with a liquid, for example water, for moistening the underside of the film web strips.
  • the cutting wheel (7) is lowered onto the film level and the film strips (4) are cut off transversely to the web direction. This leaves from the glue point (22) to the end of the film a film residue (4 ') of 5 to 20 cm, from the interface to the beginning of the suction comb (3) about 5 to 10 cm.
  • the winding device (10) rotates through 180 °, so that now on the winding shaft (13 ') already unwound cores (14') are located adjacent to the suction comb.
  • the roller (6) is pivoted away from the suction comb, whereupon the latter with the held strip ends (4) the winding shaft (13 ') with the cores (14') is pivoted to a small distance, so that it reaches the position shown in dashed lines in Figure 1.
  • On the winding cores (14 ') now come the moistened undersides of the ends of the cut strips (4) to lie.
  • the empty cores (14 ') may have been moistened beforehand by an appropriate device.
  • the outer periphery of the intermediate layer foils (21) provided between the winding cores can dip into the open gaps (25) between the segments (5) of the guide suction comb (3). This can be facilitated by the winding shaft (13 ') starting up briefly, for example, and the intermediate layers being tightened as a result of centrifugal force.
  • the winding shaft (13 ') is slowly driven then faster and the winding process begins, while at the same time the negative pressure is removed from the segments (5).
  • the suction comb is either suddenly or gradually pivoted away with the winding diameter (23 ') of the newly emerging tape roll and returns to its original position ( Figure 1).
  • the high speed up to about 1000 m / min. can take place, on the arm (12) of the device (10) all finished tape rolls (23) can be completely removed as a unit and packed ready for dispatch, for example in a packaging unit according to DE-PS 26 55 254 or DE-GM 87 16 579 and 87 16 580 or 88 03 062 from the applicant.
  • the shaft (13) is then re-equipped with empty winding cores.
  • a defined strip length of the film web is expediently formed by the cross cutting already described direction (2). This is done by cutting the foil web at certain intervals on this device with the cutting wheels (15, 15 ') while the web is stationary, then the support rail is moved downwards and the narrow piece of tape located on it is removed in some way. Then an adhesive tape (22) is applied and the two tape ends are connected to one another by the adhesive surface (20). There is a short distance between the tape ends, which can be a few millimeters to a few centimeters. If this glue point reaches the tape roll on the winding shaft (13 or 13 '), the tape end sticks and the winding process is ended. It can then be continued in a new cycle as described above.
  • the processor can then, for example for the purpose of loading or winding magnetic tape and cassettes, easily open the gluing points for each magnetic tape roll, the so-called pancake at the protruding end of the gluing point, remove the short film residues (4 ') and then according to the magnetic tape strips in loader or winder introduce the known prior art.
