Definitions

  • the invention relates to an opening roller for an open-end spinning device according to the preamble of claim 1.
  • opening rollers are known in various embodiments.
  • an opening roller which has a rear bearing shaft and is mounted with this bearing shaft in the bearing bracket of an opening roller housing.
  • the bearing has on its end a so-called drive whirl, which is acted upon by a machine-tangential belt and connected via a shaft to the main body of the opening roller.
  • ring On the rotatably mounted body of the opening roller a so-called ring is set interchangeable.
  • the opening roller can be folded away from the tangential belt and then removed forwards from the opening roller housing.
  • this opening rollers are fixed with its stator on the opening roller housing and connected via electrical lines to the power supply of the textile machine.
  • the opening roller is mounted with its bearing shaft in the bearing bracket of an opening roller housing and has a trained as an external rotor drive.
  • the known opening roller is fixed in the bearing bracket by a spring wire which engages in an annular groove of its bearing shaft.
  • a locking and unlocking device which can be actuated by a knob arranged in front of the opening roller housing, which is connected via a shaft with rear shift gate.
  • toggle can shift gates, which have different buttons are rotated so that the brake is pressed onto the whorl and at the same time the power supply of the opening roller drive is interrupted.
  • the locking of the bearing shaft of the opening roller can then be solved in the bearing bracket and the brake released again.
  • the EP 1 188 850 A2 describes an open-end spinning device with a stationary spinning box housing arranged on the machine base frame of a textile machine for supporting a spinning rotor revolving at high speed in a rotor housing susceptible to negative pressure, a sliver opening unit connected to the spin box housing via a linear guide and a cover element for closing the rotor housing, the sliver Easily detachable dissolution unit if required, is connected to a terminal console of the linear guide, where within the sliver disassembly unit a single motor driven driveable roller is arranged.
  • the present invention seeks to provide an opening roller, which is driven by a single motor, but, for example, to change their fitting ring, easily and safely from its storage console on the opening roller housing and can be removed.
  • the inventive design of an opening roller with a contact track device in the region of its bearing shaft, which corresponds with contact shoes or pins, has the particular advantage that, although a single motor driven opening roller is used in an expansion of the opening roller, as for example in connection with the replacement of the fitting ring is necessary, no electrical plug contacts or the like solved and must be reassembled during subsequent installation. On the contrary, it is ensured by the contact track device according to the invention that the drive of the opening roller can be easily disconnected from the energy supply of the relevant textile machine during its removal and can likewise be easily reconnected during installation.

  • the contact track device in the installed state of the opening roller protrudes into a contact shoe housing, that the contact tracks correspond properly with the corresponding contact shoes or pins and thus ensure reliable energy and signal supply of the opening roller drive.
  • the contact shoe housing by a simple radial displacement from a first operating position in which the contact shoes or pins are in engagement with the associated contact tracks, to transfer to a second operating position, in which Contact shoes or pins are out of engagement with the associated contact traces and thus the drive of the opening roller is de-energized.
  • the opening roller in the first operating position, a proper operation of the opening roller is possible, while in the second operating position, the opening roller can be easily taken forward from the opening roller housing and, for example, by a new or an outdated, for example, provided with a new ring gear opening roller can be replaced ,
  • the training according to claims 6 and 7 thus not only ensures that there is always a secure electrical connection to the opening roller drive during spinning operation, but also ensures that, if necessary, the Drive the opening roller is reliably disconnected from the power supply.
