Definitions

  • the invention relates to a winding shaft with a plurality of winding sleeves arranged next to one another in the axial direction, which are rotatably mounted independently of one another on the winding shaft and can be connected to the latter in a frictionally locking manner.
  • Field of application of the invention is the winding of several tapes simultaneously with a uniform winding tension.
  • Such a winding shaft is described in DT-PS 11 43 074, according to which the winding sleeves can be coupled by means of tensioning elements with shoulder rings and radially movable pressure elements, which are arranged on the shaft, are pressed against the inside of the shoulder rings.
  • the frictional connection between the individual tensioning elements and the winding sleeves can be adjusted by means of an axially displaceable sleeve with which the shoulder rings are pressed together against an adjusting ring or shaft collar.
  • An individual adjustment of the frictional coupling of the individual winding cores is therefore not possible.
  • rapid wear of the tensioning elements can occur at high rotational speeds of the winding shaft and large slippage between the tensioning elements and the winding sleeves, since these must consist of elastic material in order to produce the frictional connection.
  • Another disadvantage is that the Construction and construction of the winding shaft is complicated and expensive.
  • the object of the invention is to design a winding shaft with winding sleeves such that the frictional connections between the winding sleeves and the winding shaft can be set independently of one another and the parts exposed to friction wear out as slowly as possible.
  • this device for transmitting frictional force can be produced with little effort compared to the known ones.
  • the winding shaft according to the invention has proven particularly useful when driving the winding cores winding the magnetic tapes from a plurality of magnetic tape cassettes arranged next to one another.
  • the maximum permissible tensile stress of the magnetic tape can be set for each winding tube that engages in the toothed center opening of a winding core, from which the winding tube is no longer carried along by the winding tube.
  • the winding tube proposed according to the invention is constructed from a few simple parts, for which wear-resistant materials can be used with regard to the frictional stress.
  • spacers 3 are inserted between the individual winding tubes 2, 8, 10, 14, 21, 23, 33.
  • the winding sleeves 2, 8, 10, 14, 21, 23, 33 can themselves take up the material to be wound or can be used to drive a winding roller, for example the winding cores of a magnetic tape cassette.
  • the cross-sectional profile of the winding sleeves 2, 8, 10, 14, 21, 23, 33 is adapted to the center opening of the winding roll to be driven, in the example hexagonal.
  • the winding shaft 1, 22, 30 carries a drive part, e.g. a drive pulley or, as in Figure 1, a cross-shaped head for the motor drive.
  • a centering shaft, not shown in the drawings, is provided at the other shaft end.
  • Figures 2 to 8 show different embodiments of the winding tube and the spring elements in connection with the winding shaft, which is shown opened.
  • the center bore of the winding tube 2 for receiving a coil spring 6, which is attached to the winding shaft 1 as a key, is partially expanded.
  • the helical spring 6 is fixed at one end in a radially running bore 7 of the winding tube.
  • the desired frictional force and thus the maximum torque to be transmitted from the winding shaft 1 to the winding tube 2 depend on the number of wire windings, the wire diameter and the spring force of the helical spring 6.
  • the inside diameter of the coil spring is 3.7 + 0.02 mm.
  • the helical spring 6 is fitted onto the winding shaft 1 in such a way that it is turned on when the winding shaft 1 rotates under the action of the frictional force. As a result of the inside diameter of the helical spring 6 becoming larger, the frictional force is reduced.
  • the winding tube 2 consists of two half-shells 8, which are held together at their two constricted ends by a clamping ring.
  • FIG. 4 shows an embodiment in which the winding tube 10 has two openings, in each of which a clamping piece 11 is guided.
  • the two clamping pieces 11 are pressed against the winding shaft 1 by means of a leaf spring 13.
  • the contact pressure and thus the frictional force are set by means of a screw 12 with which the leaf spring 13 is fastened to the central part of the winding tube 10.
  • the winding sleeve 14 shown in FIG. 5 also has a leaf spring 17 which can be pressed on by means of set screws 16 and which is arranged in the central part of the winding sleeve 14 and from this loose segment 15 presses against the winding shaft 1.
  • the winding shaft 22 is surrounded by a sleeve-shaped spring 19 in the form of a cylinder cut open along a surface line, which is fixed with an angled cutting edge in a correspondingly extending groove 20 of the winding shaft 22.
  • the thus-formed spring 19 presses with its outer surface by the outwardly directed spring force against the inner wall of the winding core 21 and thereby provides the reibun g s-locking connection between the winding shaft 22 and winding tube 21 side.
  • this arrangement can also have a reverse action, ie the spring is fixed with an outwardly angled edge in a groove in the winding tube and clasps the winding shaft under the inward spring force. This version is not shown in the drawing.
  • FIGS. 7, 7a Another embodiment (FIGS. 7, 7a) provides that the winding shaft 30 is pierced radially and a helical spring 31 is introduced into the bore. This presses two hardened steel balls 32 against the inner wall of the winding sleeve 33, which in this case preferably consists of bearing metal.
  • this embodiment will be designed in such a way that two or more, offset by 90 ° and evenly over the length of the winding sleeve 33 Distributed, radial bores with springs 31 and steel balls 32 are provided. This ensures a smooth circulation of the winding sleeve 33.
  • FIGS. 8 and 8a Another possibility for establishing a frictional connection between the winding tube and the winding shaft is shown in FIGS. 8 and 8a.
  • a semicircular spring band 24 with shoulder 27 bent ends the spring element transmitting the frictional force So that this can be received between the winding shaft 1 and the winding tube 23, the central bore of the winding tube .23 is expanded semicircularly along the length corresponding to the axial extension of the spring band 24 and slotted in a plane of the central axis.
  • set screws 25 which are rotatable over the shoulder-like ends 27 of the spring band 24 in threaded bores of the winding tube, the spring band 24 can be pressed more or less against the surface of the winding shaft 1 via its ends 27 to adjust the frictional force.
