Definitions

  • the invention relates to an open-end spinning device according to the Preamble of claim 1.
  • DE 43 23 213 A1 describes, for example, an open-end spinning device with a supporting frame fixed to the machine base frame of a spinning machine.
  • the support frame has a support disk bearing arrangement, an axial bearing and a rotor housing which can be closed by a pivotably mounted cover element.
  • cover element a so-called channel plate, a fiber sliver feed cylinder, an opening roller and a one-piece fiber guide channel are arranged.
  • the opening roller is driven by a Tangential belt, while the sliver feed cylinder over one Worm gear with a machine-long drive shaft connected is.
  • duct plate adapter which next to a Thread take-off nozzle also has the mouth of the fiber guide channel, in the spinning rotor in, so that from the fiber channel opening emerging individual fibers directly to the neighboring arranged fiber slide surface of the spinning rotor are fed.
  • DE-OS 23 27 347 and DE-OS 23 27 348 show and describe rotor spinning device with such Linear guide.
  • these open-end spinning devices each have a stationary bearing housing for receiving a spinning rotor rotating in a rotor housing and a cover element which is connected to the stationary bearing housing so as to be displaceable via a linear guide.
  • a fiber ribbon feed cylinder and an opening roller are also arranged within the cover element.
  • the drive of the opening roller and sliver feed cylinder takes place through central, machine length Drive devices that are stationary in the area of the stationary Spinning rotor bearing housing are arranged.
  • open-end spinning devices in which one each within the pivotably mounted cover element single-motor-driven sliver opening roller and / or a single-motor driven sliver feed cylinder are arranged.
  • a disadvantage of the spinning device according to DE 43 09 947 A1 is that the cover element is connected to the spinning rotor bearing housing via a pivot axis which is relatively difficult to access, which, as explained above, has both a clear limitation with regard to the minimum rotor diameter and difficulties for example, possible repairs to these individual drives. That is, in these known spinning devices, the sliver opening unit integrated in the cover element with the sliver opening roller driven by the single motor and the sliver feeding cylinder driven by the single motor is also relatively difficult to remove.
  • the present invention is based on the aforementioned prior art based on the task of productivity of rotor spinning machines by increasing the spinning rotor speeds and thereby also to ensure that the spinning devices in If necessary, they are easily accessible and easy to repair.
  • this object is achieved by a device as described in claim 1.
  • the easily detachable connection of the sliver opening unit to the connection console of the linear guide also ensures that not only all components, e.g. the spinning rotor, remain easily accessible, but that the entire sliver opening unit can also be easily replaced if necessary, so that e.g. whose individual drives can be checked and, if necessary, repaired in a special workshop.
  • an open-end spinning device not only leads to a noticeable improvement in the productivity of such textile machines, but is also characterized by being easy to repair. Furthermore, essential spinning components can be exchanged quickly and safely, for example when changing lots.
  • the fiber sliver opening unit can be easily tilted about the pivot axis after releasing the locking device, so that, for example, access to the spinning rotor is largely released. Since the swivel axis is fixed in the storage slots of the connection console which are open towards the front, the sliver-dissolving unit can also be easily removed if necessary and, for example, exchanged for another sliver-dissolving unit.
  • the locking device consists, as described in claim 3, in an advantageous embodiment of a spring-loaded locking bolt, which is slidably mounted on the connection bracket of the linear guide, and a corresponding connection hole in the area of the sliver opening unit.
  • the sliver opening unit is connected to the connection bracket of the first linear guide described in claim 1 via a second, short linear guide. That is, on the connection bracket of this first linear guide, as set out in claim 4, guide bolts are arranged which slide in corresponding guide bores of a connection body of the sliver opening unit.
  • the guide bolts have in Area of their free end each have a locking groove, in which can enclose a corresponding locking means.
  • These locking means are preferably, as described in claim 6, designed as a manually actuable locking lever. That is, in the installed state, two pivotably mounted locking levers (Claim 7), preferably acted upon by a spring element in the sense of "pivoting in”, engage in the locking grooves of the guide bolts and thereby fix the sliver opening unit in a form-fitting manner on the connection bracket of the first linear guide.
  • both the sliver feed cylinder and the sliver opening roller are driven by a single motor. That is to say, in a preferred embodiment, the sliver opening roller is driven, as set out in claim 8, via an individual electric motor drive, for example a direct current or alternating current motor.
  • This single drive is preferably designed as a compact external rotor.
  • a coupling device is arranged in the area of the connection console of the first linear guide, which enables mechanical separation of the electrical and pneumatic supply lines leading to the fiber sliver opening unit.
  • the coupling device consists, as set out in claim 10, of a coupling plate arranged on the connection bracket of the first linear guide, which corresponds in the operating position of the open-end spinning device with a correspondingly designed coupling element on the connection body of the sliver-dissolving unit.
  • a coupling element arranged in the region of the fiber sliver dissolving unit is designed, for example, as a so-called “mother part”, the contact sockets of which are connected to the individual drives of the fiber sliver dissolving unit.
  • contact pins arranged on the coupling plate grip into these contact sockets and thereby form an electrically and pneumatically continuous closure.
  • connection console of the first linear guide on the back Has centering device Preferably there is Centering device consists of two hardened dowel pins, which in the operating position in the corresponding centering holes Intervene stationary bearing block (Claim 11).
  • At least one of the centering elements of the centering device functions as a key switch.
  • any relative movement between the sliver opening unit and the associated stationary pedestal immediately leads to the key switch being opened and the energy supply to the individual drives being cut off.
  • the key switch consequently ensures in a simple manner that the releasable coupling device which is switched on in the supply lines for the individual drives is always switched off or without pressure before each disconnection.
  • FIG. 1 shows the open-end spinning device according to the invention, generally designated by the reference number 1, in its operating position, that is to say in the closed state.
  • the open-end spinning device 1 has a stationary spinning box housing 2 and a sliver opening unit 4 connected to the spinning box housing 2 so as to be displaceable via a linear guide 3.
  • a bearing device 5 is arranged inside the spinning box housing 2 and accommodates, for example, an individual drive 6 for a spinning rotor 7.
  • the spinning cup of the spinning rotor 7 rotates in a rotor housing 8, which is connected to a vacuum source 10 via a pneumatic line 9 and can be closed by a seal 24 embedded in a cover element 23 of the sliver opening unit 4.
  • spinning station housing 2 As indicated, is also inside the spin box housing 2 a spinning station own energy supply and Control device 25 arranged.
  • the sliver opening unit 4 has, as usual, a opening roller housing 11 in which an opening roller 12 driven by a single motor rotates. Furthermore, the sliver opening unit 4 has a sliver draw-in cylinder 14 which is driven by a stepper motor 15. As is known, the opening roller 12, which in the present exemplary embodiment is driven, for example, by a direct-current motor 13 designed as an external rotor, breaks down a sliver 18, which is presented via a sliver compressor 16, into individual fibers (not shown).
  • the fiber sliver 18 inserted into the opening roller housing 11 between a feed trough 17 of the fiber sliver compactor 18 and the fiber sliver feed cylinder 14 is broken down into individual fibers, which are then pneumatically separated via a fiber guiding channel 19 which opens into a so-called channel plate adapter 20 which is inserted into the cover element 23 , are conveyed to the spinning rotor 7.
  • the individual fibers are fed via the mouth of the fiber guide channel 19 arranged in the channel plate adapter 20 directly onto an opposite, so-called fiber slide surface of the spinning rotor 7.
  • Thread 21 is discharged via a thread take-off tube 22 and closed a cheese (not shown) wound.
  • the first linear guide 3 essentially consists of a stationary bearing block 26 which, for example via a Welded connection, is permanently attached to the spinning box housing 2.
  • the bearing block 26 has guide bores 27 in which elongated guide members, for example two cylindrical guide rods 28, are slidably guided.
  • the guide rods 28 of this first linear guide 3 are connected at their rear end via a spacer 29, while they are fixedly mounted in a connection bracket 30 at their front end.
  • connection console 30 via a locking device 31, Guide slots 32 for a on the sliver opening unit 4th arranged pivot axis 33 and via a coupling plate 44 an electrical / pneumatic coupling device 34, which later for example, will be explained in more detail with reference to FIG.
  • the open-end spinning device 1 preferably also has a pneumatic dirt disposal device 40.
  • the dirt holding funnel 39 of this dirt disposal device 40 is positioned exactly under the dirt outlet opening of the fiber ribbon dissolving unit 4.
  • the dirt disposal device 40 either has its own vacuum source 41, as indicated in the figures, or the dirt disposal device 40 is connected directly to the vacuum system of the open-end spinning devices 1, that is to say to the vacuum source 10.
  • FIG. 2 shows the open-end spinning device 1 described above in a position in which the sliver opening unit 4 over the first linear guide 3 horizontally in a rearward position moved, that is, the rotor housing of the open-end spinning device is open.
  • the cover element 23 or the seal 24 on the sliver opening unit 4 have the front open Rotor housing 8 released so that the spinning rotor 7 already is relatively accessible.
  • the centering device 46 In the position shown in FIG. 2, the centering device 46, which is shown in more detail in FIG. This means that the centering bolts 55 of the centering device 46, which are generally hardened, have left their associated centering holes 56. At least one of these centering bolts 55 has released a plunger 57 of a key switch 47 which is acted upon by a spring element 58 and thus ensured that the energy supply to the individual drives 13, 15 in the sliver opening unit 4 was interrupted.
  • the sliver opening unit 4 can, as indicated in FIG. 3, be tilted about the pivot axis 33 and, if necessary, by the bearing columns 32 which are open towards the front can be removed without problems. During this tilting process, the currentless and pressure-free electrical / pneumatic coupling device 34 is also separated.
  • a coupling element 45 arranged on the sliver opening unit 4 the electrical component of which has, for example, spring-loaded contact pins, is pivoted back with the sliver opening unit 4 such that these contact pins lose their mechanical contact with the contacts 59 of the coupling plate 44.
  • a pneumatic coupling 60 is also separated, which is connected to the pneumatic lines 35.
  • FIGS. 6 and 7 show a further possible embodiment of such a first linear guide 3.
  • a box-like hollow profile 52 is provided here.
  • the hollow profile 52 is slidably mounted in a recess 53 of a stationary pedestal 26 and preferably, as can be seen in particular from FIG. 7, has spaced sliding surfaces 61 on its outside. These sliding surfaces 61 are guided in a bearing bush 54 which is fixed in the recess 53 of the bearing block 26 and is made, for example, of brass. That is, the one or two-part bearing bush 54 guides the hollow profile 52 over a large area, so that a stable guide device is provided.
  • a channel 62 arranged within the hollow profile 52 can thereby can be used to accommodate the supply lines 35, 36.
