Definitions

  • the invention relates to an opening roller for an open-end spinning device according to the preamble of claim 1.
  • opening rollers in various embodiments are known.
  • 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 end of the bearing shaft has a so-called drive whorl, which is acted upon by a machine-long tangential belt and is connected to the base body of the opening roller via a shaft.
  • a so-called clothing ring is interchangeably fixed on the rotatably mounted base body of the opening roller.
  • the opening roller can be folded down from the tangential belt and then removed from the front of the opening roller housing.
  • opening rollers are known which are driven by a single motor.
  • Opening rollers are fixed with their stator to the opening roller housing and connected to the power supply of the textile machine via electric lines.
  • a clothing ring is also interchangeably arranged on the rotor of this external rotor.
  • a disadvantage of these single-motor-driven opening rollers is that the drive of the opening roller must also be removed in order to change the clothing ring, and electrical lines or corresponding plug connections must be disconnected. These plug connections must then be carefully reassembled when the opening roller is reinstalled. The installation and removal of such opening rollers is therefore relatively cumbersome and time-consuming.
  • Bearing shaft is mounted in the bearing bracket of an opening roller housing and one designed as an external rotor
  • a whorl is arranged at the end, which can be acted upon by a braking element.
  • the known opening roller is fixed in the bearing bracket by a spring wire which engages in an annular groove in its bearing shaft.
  • a locking and unlocking device which can be actuated by a toggle arranged in front of the opening roller housing, which is connected via a shaft to the rear shifting gate.
  • the invention has for its object to provide an opening roller which is driven by a single motor, but can be easily and safely installed and removed from its bearing bracket on the opening roller housing, for example for changing its clothing ring.
  • an opening roller according to the invention with a contact track device in the area of its bearing shaft, which corresponds to contact shoes or pins, has the particular advantage that, even though an opening roller driven by a single motor is used, the opening roller is removed, for example in connection with the replacement of the trim ring is necessary, no electrical plug contacts or the like must be loosened and reassembled during the subsequent installation. Rather, the contact track device according to the invention ensures that the drive of the opening roller can easily be decoupled from the energy supply of the textile machine in question when it is removed, and can also be easily recoupled during installation.
  • the contact track device in an advantageous embodiment has a plurality of galvanically isolated
  • contact traces include the stock of the
  • contact track device in or on a plastic body, which can be fixed, for example, by a clip connection on the bearing shaft of the opening roller.
  • the relatively sensitive contact track device is largely protected against external mechanical influences.
  • the contact track device in the installed state of the opening roller protrudes into a contact shoe housing that the
  • Contact traces correspond to the corresponding contact shoes or pins and thus ensure a reliable power and signal supply to the opening roller drive.
  • the contact shoe housing as described in claim 8, is fixed to a spring element, preferably a leaf spring.
  • the spring element rests with a preload on a rotatably mounted switching structure that has several buttons of different heights.
  • the contact shoe housing can radially to the bearing shaft of the
  • the switching contour can advantageously be actuated via a toggle which is arranged in the region of the opening roller housing in an easily accessible manner.
  • the easy accessibility of the toggle enables the operating personnel to set the desired operating position of the contact shoe housing easily and quickly. Since a fixing element of a locking and unlocking device is also controlled via the switching contour in addition to the contact shoe housing, a problem-free, completely uncomplicated exchange of the opening roller is possible if required.
  • the locking and unlocking device preferably has a bar spring as the fixing element, which in a first operating position is spring-loaded into a locking ring fixed on the bearing shaft of the opening roller (claim 11).
  • the rod spring not only secures the bearing shaft of the opening roller against displacement due to mechanical loading in the axial direction, but also prevents the bearing shaft from rotating under the influence of the torque of the opening roller drive.
  • the open-end spinning device has a stationary stop (claim 12).
  • this stationary stop When the spinning device is closed, this stationary stop covers the leaf spring resting on the switching contour and carrying the contact shoe housing. This means that the stationary stop prevents the toggle from pivoting and thus the contact shoe housing and the fixing element from being able to be brought into an operating position in which correct operation of the opening roller is no longer guaranteed.
  • the stationary stop also prevents the spinning device from being closed when the switching contour is in an operating position in which neither the contact shoes rest on the contact tracks nor the locking and unlocking device locks the bearing shaft of the opening roller.
  • Contact track device can be made, for example, from a conductor foil, which is preferably fixed on a plastic support body after punching out.
  • the plastic body is then fixed to the bearing shaft of the opening roller by means of a suitable connection mechanism, for example via a clip connection. This means that the support body equipped with a conductor foil is reliably connected to the bearing shaft of the opening roller via the clip connection and a corresponding abutment.
  • FIG. 1 shows schematically an open-end spinning device with an opening roller that can be driven by a single motor and whose energy supply has a decoupling contact track device
  • 5 a single-motor driven opening roller with a contact track device in detail
  • 6 a contact track device, for example produced by means of a conductor film, before it is attached to the bearing shaft of the opening roller.
  • FIG. 1 shows one of the numerous open-end spinning devices 1 of an open-end rotor spinning machine.
  • Such open-end spinning devices 1 are known in principle and are described in relatively detail, for example in DE 196 50 597 AI.
  • such open-end spinning devices 1 have a spinning rotor 2, the rotor cup 4 of which during the
  • Pneumatic line 6 connected to a vacuum source 7, which provides the vacuum required for spinning in the rotor housing 5.
  • the spinning rotor 2 is electromotive
  • Individual drive 3 which is connected, for example, via electrical lines 20 to the energy supply 27 of the textile machine in question, can be driven in a defined manner.
  • the electromagnetic single drive 3 is additionally connected to associated control electronics 23 via at least one signal line 24.
  • the cover element 8 which closes the rotor housing 5 during the spinning operation, is rotatably supported to a limited extent about a pivot axis 16, so that the stationary spinning rotor 4 is accessible when required.
  • a so-called channel plate adapter 9 is also interchangeably inserted in the cover element 8, to which a thread take-off tube 10 is connected.
  • the cover element 8 has an opening roller housing 11, in which an opening roller 12 rotates, which is fixed with its bearing shaft 17 in a rear bearing bracket 14 of the opening roller housing 11 and is thereby secured by a locking and unlocking device 26.
  • the locking and unlocking device 26 consists of a spring element 32, preferably a bar spring, which springs into a locking ring 33 arranged on the bearing shaft 17 of the opening roller 12.
  • Single drive 28 which is designed as an external rotor, is driven and has an easily detachable coupling to one
  • the contact track device 18 consists of several galvanically isolated contact tracks 19, which are in the end region of the
  • Bearing shaft 17 are annular.

  • Signal device 27 of the open-end rotor spinning machine or via a signal line 22 are connected to a control device.
  • the contact shoes 21 are protected in one
  • Contact shoe housing 50 arranged, which, as will be described later explained, radially to the bearing shaft 17 of the opening roller 12 is slidably mounted.
  • the contact shoe housing 50 is fixed with limited movement on the housing of a drive 36 of the sliver feed cylinder 13 via a spring element 35, preferably a leaf spring.
  • Unlocking device 26 serving rod spring 32 abut buttons 30A to 30D of a switching contour 29 which can be pivoted in a defined manner by a toggle 31 arranged in the area of the opening roller housing 11. This means that either a first operating position A (spinning mode) or a second operating position B (assembly setting) can be defined by the knob 31.
  • a stationary stop 34 is also provided on the open-end spinning device 1, which overlaps the spring element 35 when the spinning device is closed and thereby prevents the switching contour 29 from operating position A into operating position B by means of toggle 31 can be switched.
  • the opening roller 12 has both fixed and rotatable ones
  • the fixed components include the bearing shaft 17 with the contact track device 18 and the stator winding 39 of the opening roller drive 28.
  • the rotor of the Opening roller drive 28 forms is rotatably supported on bearing shaft 17 of opening roller 12 via roller bearings 44 or 45.
  • an exchangeable clothing ring 42 is arranged on the base body 41 and is secured by a so-called flanged disc 43.
  • Control device are connected.
  • the bore 51 of the contact shoe housing 50 is designed so that a radial displacement of the
