Definitions

  • the invention relates to a friction winding shaft, in particular for reel cutting and winding machines, according to the preamble of claim 1.
  • Roll cutting and winding machines are known (DE-OS 28 56 066), in which wide webs are drawn off from a supply roll and then divided into strip-like strips. These are wound on tubular cores, which are attached to a friction winding shaft. To wrap up the strip-shaped strips, two spaced-apart friction winding shafts are provided, with every second strip-shaped strip being wound on the one friction winding shaft and the strip-shaped strips between them being wound on the second friction winding shaft.
  • the thrust pieces are designed here as three pressure strips running in the longitudinal direction of the drive shaft and are designed such that they can adapt to different inner diameters of adjacent rings at least in the longitudinal direction.
  • the rings used to hold the winding cores are provided on the outer surface of the ring with elastic projections, in particular spring plates, which are oriented somewhat inclined to the radial in the drive direction and lie against the inner surfaces of the winding core in accordance with the spring tension.
  • elastic projections in particular spring plates, which are oriented somewhat inclined to the radial in the drive direction and lie against the inner surfaces of the winding core in accordance with the spring tension.
  • winding core holders in the form of spring-loaded rotating parts as clamping bodies with contact edges projecting from the outer surface of the holding ring.
  • This roof-shaped too designed contact edges are slightly inclined to the radial in the drive direction and also lie on the inner surface of the winding core in accordance with the spring tension.
  • the winding cores are usually made of paper material or plastic with relatively large tolerances.
  • the diameter tolerances of the inner core diameters of the winding cores are recorded in the available spring travel of the winding core holder, this spring travel having to be available with a correspondingly large dimension.
  • a similar winding shaft is known (DE 39 18 863 A1), in which the friction rings are provided with oblique guides for winding core supports.
  • the inclined guide is designed in such a way that the winding core supports can be moved in the range of the diameter tolerances of the cores.
  • the object of the invention is to develop a generic friction shaft so that improved centering and Alignment of the attached winding cores takes place and thus there are no vertical changes and wobbling movements of the winding cores.
  • the rings are each divided into two independent, concentric rings. They therefore consist of an inner friction ring and an outer retaining ring.
  • the thrust pieces for frictional engagement with the drive shaft rest on the inner surface of the friction ring and the winding core holders are attached to the outer surface of the holding ring.
  • the friction ring and the associated retaining ring can be rotated against each other.
  • At least one oblique guide (with an oblique with respect to a concentric circular path) is attached in the outer surface of the friction ring.
  • At least one winding core support penetrating the holding direction is arranged on the retaining ring, which engages or interacts with the inclined guide on the friction ring in such a way that when the retaining ring is rotated relative to the friction ring against the direction of rotation of the drive shaft, the winding core support extends beyond the retaining ring outer surface into a contact position is movable to the inner core surface of an attached winding core.
  • the inclined position and length of the inclined guide are dimensioned such that the winding core support can be moved at least in the range of the diameter tolerances of the winding cores used with the available forces.
  • the diameter tolerances are only a few millimeters, so that the maximum height of the inclined guide must also be dimensioned in this way.
  • the inclination with respect to a circular path should not be chosen to be too steep, so that the setting and movement of the winding core support can be carried out with relatively low forces.
  • the winding cores are placed on the friction shaft and held in position by the winding core holders under pre-tension, whereby the centering and transverse alignment may not yet be optimal. If after the start the drive shaft starts to turn, the friction ring is rotated in the same direction by friction. The retaining ring with the winding core attached is held back by the tape tension of the tape already placed, whereby the friction ring initially rotates with respect to the retaining ring in the direction of rotation of the drive. As a result, the positive control of the winding core supports via the inclined guides on the friction rings is activated in such a way that the winding core supports are moved outward beyond the outer holding ring surfaces until they come into a contact position on the inner winding surface. This stops their forceps movement and at the same time creates a tight form fit between the friction ring and the retaining ring, as a result of which both rings continue to rotate together in the direction of rotation of the drive.
  • This fixed winding core support (compared to the known elastic mounting of the winding cores on the elastic or spring-loaded winding core supports) achieves an improved and movement-free adjustment of the winding cores on the friction winding shaft.
  • the winding core supports are activated and moved automatically when a winding process is started.
  • this consists of a pressure pin held in a radial guide, which is held in a guide penetrating the retaining ring. Depending on the position of the inclined guide, the pressure pin can be moved more or less outwards beyond the outer surface of the retaining ring.
  • the winding core support consists of a torsion support part rotatably mounted on the retaining ring and penetrating the retaining direction.
  • This can be implemented, for example, in the manner of an angle lever, with one lever arm engaging in the oblique guide and the other lever arm being pivoted out beyond the retaining ring outer surface when the retaining ring is rotated relative to the friction ring up to a contact position on the inner surface of the winding core.
  • the inclined guide on the friction ring can be formed in a simple manner as an inclined surface on the friction ring outer surface.
  • the winding core support in particular a pressure pin, can then be slid directly onto such an inclined surface, with a return spring advantageously being brought back into the retracted one Position is carried out.
  • the inclined guidance is also possible in addition or optionally as a link guide, the extension and retraction of the winding core support being forced by a sliding connection between a guide part of the winding core support and the link guide.
  • a return spring is not required.
  • an anti-rotation device for the winding core supports is proposed according to claim 8.
  • this can be designed such that the ends thereof are bent towards the central drive shaft and between thin washers in the ring diameter are provided for the individual rings.
  • An alternative or additional anti-rotation lock can be implemented in a simple manner when using a pressure bolt in that it is held prismatic, that is to say not cylindrical, in a correspondingly designed prismatic guide.
  • a window is provided in the associated guide part, through which the return spring, preferably made of spring wire, can be connected to the pressure pin.
  • winding core supports are returned to their retracted starting position. This can be done in particular in the case of spring-loaded pressure bolts by sliding back on the inclined guide in connection with a rotation of the retaining ring with respect to the friction ring.
  • the return torque can, however, be relatively small with a slight inclination to incline, so that inhibitions can occur which make manual reset necessary.
  • the spring force of the return spring is to be dimensioned so that it is less than the force generated by the belt tension during the winding process between the retaining ring and the friction ring, so that during the winding process the rotation between the retaining ring and the friction ring for moving the winding core support is possible.
  • a friction winding shaft with winding core supports it is also advantageous in the embodiment according to the invention of a friction winding shaft with winding core supports to carry out the pressure pieces as pressure running in the longitudinal direction of the drive shaft, at least three being arranged offset on the circumference.
  • the pressure strips should adapt to different inner diameters of adjacent friction rings at least in the longitudinal direction.
  • the control of the pressure is carried out in a manner known per se by means of inflatable inflation tubes used in the receiving spaces below the pressure bars.
  • the entire effective length of the drive shaft should be occupied with rings of small width, which enables the easy use of winding cores of different widths.
  • these are advantageously to be made in the width of the rings for the largest possible contact surface.
  • winding core brackets are preferably each offset from the winding core supports and attached between them.
  • the winding core holders are also spring-loaded rotary parts in a manner known per se as clamping bodies with projecting edges projecting from the outer surface of the holding ring. These are slightly roof-shaped and slightly inclined to the radial in the drive direction and lie against the inner surface of the winding core in accordance with the spring tension.
  • a roll cutting and winding machine 1 in which a wide web of material 3 is drawn off from a supply roll 2 and divided into eight strip-shaped strips 5 lying next to one another by adjacent knives 4.
  • the tapes 5 are wound up with friction winding shafts 6, 7, one band each being wound on the friction winding shaft 6 and the adjacent band on the friction winding shaft 7.
  • the friction winding shaft 7 is shown in more detail in FIGS. 2 and 3.
  • the friction winding shaft 7 consists of a central drive shaft 8 with three longitudinal grooves 9 offset on the circumference, in each of which a pressure bar 10 pointing to the outside and an inflation hose 11 are contained.
  • Rings 12 are attached to the drive shaft 8 and are shown in more detail in FIGS. 5 and 6.
  • Thin washers 13 are inserted in the outer diameter of the rings 12 between the rings 12.
  • the rings 12 lie against each other tightly and rotatably via the washers 13 and become held together in the axial direction by laterally fixed end pieces 14.
  • Tubular winding cores 21 are placed on the rings 12 and are held by means of prestressed winding core holders 16.
  • the rings 12 are so narrow that, as a rule, several rings 12 are covered by one winding core 21.
  • the ring 12 is concentrically divided into two independent rings, an inner friction ring 17 and an outer retaining ring 18, which can be rotated relative to one another (arrows 48, 49).
  • the pressure bar 10 bears against the friction ring inner surface 19.
  • the winding core holders 16 are arranged offset on the circumference of the retaining ring outer surface 20.
  • a tubular winding core 21 is plugged onto the holding ring 18, the inner diameter of which is somewhat larger than the outer diameter of the ring 12, so that a tolerance-dependent distance 23 results between the outer surface 20 of the holding ring and the inner surface 22 of the winding core.
  • the winding core holder 16 consists of a spring-loaded rotating part as a clamping body 24 (arrow 25 corresponds to the direction of the spring force).
  • the clamping body 24 rests under spring tension with a roof-shaped edge 26 on the inner surface 22 of the winding core and thus also bridges the distance 23.
  • winding core supports 27, 28 are provided distributed around the circumference.
  • the winding core support 27 consists of a pressure pin 29 which is movably guided in a radial guide 30 on the retaining ring 18. With its inner end, the pressure pin 29 bears against an inclined surface 31 which extends obliquely to the outer friction ring surface.
  • the (alternative) winding core support 28 consists of a torsion support part 32, which is rotatably mounted on the retaining ring 18 (axis of rotation 33) and which engages with a molded guide part 34 in a slot 35 of an inclined link guide 36.
  • a return spring 37 is also arranged, which is designed here in a schematic diagram as a compression coil spring.
  • the arrangement shown has the following function: At the beginning of a winding process, the winding cores 21 are placed on the rings 12, the winding cores being pushed on with a clockwise rotation. As a result, the edges 26 of the winding core holders 16, which are inclined with respect to a radial, are pivoted toward the outer surface 20 of the holding ring, as a result of which the winding cores 21 can be pushed on. Subsequently, the plurality of winding core holders 16, offset on the circumference, hold the winding cores 21 in the position shown with the spacing 23. Now the tapes to be wound are fastened to the winding cores 21 and the drive shaft 8 is started in the drive direction according to arrow 38. At the same time, the inflation hose 11 has already been inflated, as a result of which a frictional engagement with the friction ring 17 takes place via the pressure bar 10, so that it rotates together with the drive shaft 8 in accordance with the arrow 48.
  • the retaining ring 18 is rotated further to the right relative to the position shown, so that the pressure pin 29 or the guide part 34 lie at the lowest point of the inclined surface 31 or the link guide 36; the pressure pin 29 and the torsion support part 32 then protrude not beyond the retaining ring outer surface 20, so that they do not interfere with the winding cores 21.
  • the distance 23 is fixed (and not resilient, as bridged via the winding core holders 16), as a result of which the winding cores 21 are centered and aligned precisely.
  • a fixed coupling between the friction ring 17 and the retaining ring 18 is then produced in the drive direction of rotation, so that the winding cores 21 then also rotate in the drive direction (arrow 39).
  • a specific embodiment of a ring 12 is shown from two side views, each with three offset and modified winding core supports 27.
  • the pressure pin 29 is held here in a tubular guide 30 which has a window 40 on one side.
  • a return spring 42 in the form of a spring wire is inserted into a slot 41 on the pressure bolt 29.
  • the return springs 43 (arrow 25 in Fig. 4) for the winding core holders made of spring wire.
  • a flat contact part is firmly connected as a shell part 44 in the width of the ring 12 (see FIG. 2).
  • the curvature corresponds approximately to the curvature of the outer ring surface.
  • the retaining ring outer surface here is largely formed between the winding core holders 16 by the adjustable shell parts 44, so that essentially an increase in the effective contact area for the winding cores 21 is achieved.
  • the shell part 44 is here made of a spring plate, with a curvature (dashed line 45) that is greater than that of the inner winding surface 22. Under load, the shell part 44 then, as shown, lies flat against the inner winding surface 22 .
  • a prismatic pressure pin 29 is shown, which is only linearly displaceable and cannot be rotated in a correspondingly designed guide (not shown).
  • the present invention achieves a significant improvement in the centering and alignment of winding cores on friction winding shafts.
