Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Such a device is known for example from US-A-2,651,900.
  • US-A-2,651,900 To replace a tape roll, the handling by reaching behind and under is very cumbersome.
  • FIG. 1 shows a device 1 for releasably receiving a winding core 2 of a tape roll 3 on a mandrel 4 by means of a spring-loaded, manually operated tape roll changing device, the mandrel 4 being arranged axially rotatably on a fixed bearing journal 5.
  • the mandrel 4 is provided with a hub 6 which is connected to a disk 7.
  • a spring ring 9 with an axial play is arranged concentrically between the hub 6 and a shoulder 8 of the mandrel 4. In the relieved state, the spring ring 9 has a larger outer diameter than an inner diameter of the winding core 2.
  • the winding core 2 is rotatably connected to the mandrel 4 via the spring ring 9, the mandrel 4 having a smaller diameter 11 than the inner diameter 10 of the winding core 2.
  • a first free end 12 of the spring ring 9 is movably connected to the mandrel 4 and a second free end 13 of the spring ring 9 is connected to the hub 6, the mandrel 4 being connected to a freewheel device 14 is provided and the journal 5 is provided as a freewheel shaft.
  • a circlip 9A with openings 15, 16 arranged within the outer diameter is provided as the spring ring 9, one opening 15 being connected to the mandrel 4 via a pin 17 and another opening 16 being connected to the hub 6 via another pin 18.
  • the two pins 17, 18 are shown diametrically opposite one another, the correct position being evident from FIG. 2, likewise from the top view of the device 1 according to FIG. 3.
  • the disc 7 is rotated in the direction of an arrow 19 (FIG. 3), the freewheel device 14 preventing the mandrel 4 from rotating in this direction, with the result that the one rotating in the direction of the arrow 19 Disc 7, the hub 6 and thus the pin 18 are taken along in such a way that the circlip 9A is pressed together and thereby assumes approximately the outer diameter 11 of the mandrel 4, whereby the winding core 2 can be released.
  • non-slip actuation elements 20 can be provided, which are preferably arranged radially at the edge region of the disc 7.
  • the direction of tape roll unwinding is opposite to the direction of arrow 19 because of the freewheel device 14.
  • the two pins 17, 18 are arranged radially to the longitudinal axis of the bearing journal 5 in order to prevent the tape roll 3 from being imbalanced.
  • the two pins 17, 18 can either be fixedly connected to the circlip 9A and rotatably to the mandrel 4 / hub 6 or fixedly to the mandrel 4 / hub 6 and rotatably connected to the circlip 9A.
  • a holding device for axial fixing for example in the form of a circlip 21, is provided.
