Description

  • The present invention relates to a method and a device according to the preambles of claims 1 and 4.
  • From DE-OS 22 07 556 it is known to choose the winding tape wider than the width of the shingled stream when winding up printing sheets resulting in scale formation, so that the winding tape forms a separating layer in the roll between the scale layers. When winding cross-broken printed sheets with such wide wrapping tapes, highly elastic wrapping tapes with a precisely defined tension-elongation behavior are required if the wrapping is not to be loose or tapered on one side. However, since in a publishing house, depending on the product to be manufactured, the winding material itself can vary with regard to the number of pages and paper quality and consequently can have different deformation behavior, it is practically impossible to achieve a full "cylindrical" winding made of cross-broken printed sheets with a winding tape acting as a separating layer. In addition, such wrapping tapes are subject to high procurement costs due to their varying, differentiated properties and are not economically viable.
  • Instead of using wide winding tapes when winding printed sheets into a winding, DE-OS 33 15 496 proposes that a narrow winding tape be used in a serpentine manner using a movable tape guide around the longitudinal center line of the shingled stream on the roll being formed.
  • Since, in this proposal, a substantially uniform strip tension is provided in the inlet area over the strip cross-section, a "conical" winding cannot be avoided in this way when winding cross-broken printed sheets.
  • From DE-OS 25 44 135 it is further known to wind overlapped flat workpieces with two spaced, parallel, narrow winding tapes to form a winding. Both winding tapes are guided over common guide and tension rollers and lay against the adjacent edge of the shingled stream at the same distance. Since there are no means for individually adjusting the tensile stress in the two belts in this older device, "conical" windings cannot be avoided when winding cross-broken workpieces. The same applies to the device according to EP-OS 316 563, which also works with two narrow winding tapes.
  • Since none of the known solutions could prevent the formation of "conical" coils, this disadvantage was accepted and in practice winding with a single narrow band prevailed, as can be seen from EP-OS 135 080. The only narrow winding band lies exactly in the longitudinal center of the wound scale formation or in the middle between the circular side surfaces of the winding. This creates a constriction in the middle of the peripheral surface of the roll, but this is without disadvantage as long as the printed products have a uniform thickness.
  • If, on the other hand, multi-sided, cross-broken printed products are wound up, the roll takes on a conical shape and reaches its maximum possible diameter long before the maximum possible number of printed products in the wound strip length is wound up.
  • The object of the present invention is to improve the method and the device of the type mentioned at the outset in such a way that a conical shape of the winding can be largely suppressed, in particular when producing large windings.
  • According to the invention, this object is achieved by the characterizing features of claims 1 and 4.
  • The invention is explained, for example, with the aid of the attached schematic drawing. Show it:

    Fig. 5
    a same partial section as Fig. 3 of a second example of a winding produced according to the invention and
    Fig. 6
    to 8 three variants of the invention.
  • FIG. 1 shows a winding or unwinding station with a frame 1, in which a conveyor line 2 ends in the form of an endless belt. A rocker 4 is pivotally articulated on the deflection axis 3 of the belt 2 and can be pivoted up and down vertically by means of a hydraulic or pneumatic cylinder piston unit 5. The ends of the cylinder-piston unit are articulated on the frame 1 on the one hand and on the rocker 4 on the other. The rocker 4 also carries guide rollers 6, around which an endless belt 7, which can be driven with the belt 2 or independently of it, is guided. In the swivel range of the rocker 4 there is a stationary or transportable winding frame 8, on which a winding core is freely rotatable about an axis 9. If the rocker 4 is placed by means of the cylinder-piston unit 5 while the belt 7 is running with the latter in a frictional manner on the winding core 10, this is rotated in the direction of movement of the belt 7.
  • On the axis 9, a tape supply reel 11, 11 'for a respective winding tape 12, 12' are rotatably supported on both sides of the winding core 10. During the winding of a winding 13, the tape supply spools 11, 11 'are braked and put the winding tape 12, 12' under tension. During the unwinding of the roll 13, the tape supply spools 11, 11 'are driven. The tape supply spools 11, 11 'can be driven and braked either from organs mounted outside the winding frame 8 (as described, for example, in EP-S 135 080) or from the winding core 10 via a geared connection, as described, for example, in CH application 3334 / 90 is described. Below the winding core 13 are two transversely in the winding block 8 Spindles 14, 14 'spaced apart from one another and parallel to the winding axis of rotation 9 are rotatably supported. Two bodies 15, 15 'are mounted on these in a longitudinally displaceable manner. Body 15 engages spindle 14 and body 15 'engages spindle 14' through a nut thread. The body 15 is thus displaced by rotating the spindle 14 and the body 15 'is displaced in the longitudinal direction of the spindle by rotating the spindle 14'. The two spindles 14 and 14 'are, as indicated by dash-dotted lines in FIG. 1, in operative connection with fixed drives 22, 22' or drive energy sources. Servomotors are suitable as drives. The drive connection between the drives 22, 22 'on the one hand and the spindles 14, 14' on the other hand can be released by couplings in the case of a mobile design of the winding block 8. If the drives 22, 22 'are mounted in the winding block 8 and designed as electrical or pneumatic drives, they can be connectable to the corresponding stationary drive energy sources 22, 22' via an electrical or pneumatic coupling.
  • The two bodies 15, 15 'carry deflecting rollers for the winding tapes 12, 12' in order to guide them from the tape supply spools 11, 11 'to the winding core 10 and the winding 13, respectively. The guidance of the winding tapes 12, 12 'and their course in the winding block 8 correspond, which is why the description of the guidance of one of the two tapes is sufficient. The winding tape 12 is attached at one end to the tape supply reel 11 and at the other to the winding core 10. From the tape supply reel 11, it first runs down to a deflection roller (or pin) 16. From there it is deflected horizontally to a deflection roller 17 and rotated between these two deflection rollers by 90 ° about its longitudinal axis. There it bends by 90 ° horizontally to a deflection roller which is not visible in FIG. It runs tangentially from the deflection roller 18 to the winding core 10.
  • If the winding core 10 or the winding 13 is driven by the running belt 7 in the winding direction, the scale stream 19 brought up on the conveyor belts 2, 7 is guided into the winding gap 20, clamped between the winding belts 12, 12 'and the winding core 10 or winding 13 , taken away and wound into a wrap. If the two bodies 15, 15 'have the same distance from the central plane 21 perpendicular to the axis 9 during winding, the spirals formed by the winding tapes 12, 12' in the winding 13 also have the same distance from it. However, this type of winding with its disadvantages is known. If the products to be wound up are cross-broken printed sheets, they are thicker on one flat side of the roll 13 than on the other and apply more in accordance with the difference in thickness. The result is a so-called "conical" winding with the disadvantages mentioned at the beginning, in which the circle diameter on one winding side is larger than on the other. Such a winding 13 is indicated in Figure 3. If this inequality is to be avoided, the spindle 14 'is rotated and the body 15' with its deflection rollers 16 'to 18' shifted outwards from the central plane 21. The rollers 16 ', 18' (like the rollers 16, 17, 18) form side-effective guides and are provided, for example, with two wheel flanges for this purpose. When it is shifted to the side, the winding tape 12 'is also displaced accordingly and forms a spiral in the winding 13, the distance from the central plane 21 of which corresponds to the distance of the deflection roller 18' from the central plane 21. The closer the wrapping tape 12 'is shifted to the wrapping side, the more it compresses the printed sheets in the region of the cross fold and a cylindrical wrap is created (FIG. 4). If necessary (in order to achieve an exact compensation of the peripheral winding surface), the winding tape 12 or the spiral formed by it in the winding 13 can also be displaced appropriately by rotating the spindle 14 relative to the central plane 21.
  • However, it is not necessary (as described in this example and shown schematically in FIG. 6) to form a spiral with both winding tapes 12, 12 '(or in the case of several winding tapes at least two) in the winding 13, the two distances of which with respect to FIG Middle level 21 is selectable and adjustable. It is sufficient (shown schematically in FIG. 7) if the winding band 12 'or the spiral formed by it, which is closest to the winding side formed by the cross fold, can be moved. In this case, the body 15 is at a constant distance from the central plane 21 and only the body 15 'is displaceable.
  • With the invention, however, a winding with the same side diameters can also be achieved with a single winding tape 12 ″ if the distance of the winding tape spiral from the central plane 21 is selected accordingly. Here, the band 12 with the associated elements 11, 15, 16, 17 and 22 can be omitted.
  • Other devices known to the person skilled in the art, such as lever systems, etc., can also be used for the lateral adjustment of the winding tapes 12, 12 '. Instead of the deflection rollers 16, 17, 18, the tape supply spools 11, 11 'could be arranged upstream in the area of the rollers 16 and the winding tapes 12, 12' could be guided by them directly to the winding core or winding. The side flanges of the tape supply reels 11, 11 'form the side-effective guides. In this case, the tape supply reels 11, 11 'with the bodies 15, 15' are laterally adjustable on these.
  • If the winding brackets 8 with the winding core 10 or winding 13 are transportable units, the drives 22, 22 'with the associated control means for the lateral adjustment of the holding straps are preferably arranged in the stationary part, that is to say arranged on the frame 1, and coupled to the mobile part. This embodiment offers the advantage that the winding tapes 12, 12 'can be automatically adjusted to a preselected position if a winding stand 8 is placed over the rocker 8 for a winding or unwinding process. In addition to the coupling means for the drive 22 of the spindles 14, 14 'which are shown schematically in FIG Sensors, not shown, are necessary for scanning the winding tape position. Such an automated adjustment device additionally offers the advantage that the adjustment process can also be carried out during winding.
