Definitions
- the invention relates to an open-end spinning device according to the preamble of claim 1.
- the channel plate adapter In a recording of the cover element, by means of bolts, pass through the corresponding through holes in the cover element, the channel plate adapter interchangeable fixed.
- a cylindrical pin is provided, which is embedded in a bore of the cover element and corresponds with a corresponding fitting bore on the back of the channel plate adapter.
- a disadvantage of this known open-end spinning device is especially the somewhat complicated type of attachment of the channel plate adapter. That is, in a batch change, in which, for example, all spinning rotors of an open-end rotor spinning machine and thus all channel plate adapter are replaced, always at each of the numerous workstations of the textile machine initially awkward, the two bolts are unscrewed, which is relatively time consuming.
- the open-end spinning device described in DE 195 24 837 B4 also has a pivotably mounted cover element for closing the rotor housing during the spinning operation, the cover element also having a receptacle for a channel plate adapter in addition to the known lip seal element.
- the channel plate adapter is locked in this recording by means of a bar spring so that the channel plate adapter can be removed if necessary by bending back the bar spring quickly and easily.
- the rod spring fixed to the cover element grasps for locking the channel plate adapter in a Tangentialnut, which is incorporated in the conical contact surface of the bearing body of the channel plate adapter.
- DE 196 17 527 A1, DE 197 29 192 A1 or DE 198 36 073 A1 also discloses open-end spinning devices in which it is avoided when fixing the channel plate adapter in a corresponding receptacle of a cover element that the associated fastening means engage on one side ,
- DE 196 17 527 A1 relates, for example, to an open-end spinning device in which the channel plate adapter is fixed in the installed state both positively and positively in a receptacle of the cover element.
- a magnetic coupling is provided in this case, while the positive connection via a centrally arranged threaded connection.
- the channel plate adapter is here but purely magnetic in the associated recording of
- the rotor housing vacuum-pressurized during the spinning operation is closed by a pivotally mounted cover element, which has a lip seal element arranged in an annular groove and an opening in the direction of the rotor housing for a channel plate adapter.
- the associated channel plate adapter has on its back on a central extension, which is equipped with outwardly projecting abutments for a fastener.
- the rear projection penetrates a corresponding hole in the receptacle of the lid member and is acted upon by a fastener arranged on the cover element so that the conical bearing body of the channel plate adapter is uniformly or almost evenly pulled into the receptacle of the cover element, the bearing surfaces correspondingly conical are formed.
- Lip seal element equipped lid member is equipped with a central bearing opening for a channel plate adapter.
- the bearing opening in the cover element is designed so that the channel plate adapter can be installed from the outside.
- the channel plate adapter can also be closed
- Spinning device is inserted into the bearing bore and fixed there by a special locking element.
- This special locking element is around a horizontal
- the present invention seeks to develop a cost-effective open-end spinning device, in which a channel plate adapter not only reliable and easily replaceable when needed in a recording of the lid member can be fixed, but also ensures that it can not come to the emergence of false air currents and the associated contamination in the region of the cover element when the cover element is closed.
- a channel plate adapter which has a circumferential sealing surface abutting the rotor housing when the cover element is closed and is equipped with attachment projections arranged on the rear side, which in the installed state of the channel plate adapter correspond with associated fastening means in the region of the receptacle of the cover element, not only has the advantage that the channel plate adapter due to evenly introduced pressure force can be exactly fixed in the receptacle of the cover element, but the circumferential sealing surface of the channel plate adapter also ensures that can reach from the rotor housing no negative pressure in the area behind the channel plate adapter. That is, by the voltage applied to the rotor housing, circumferential sealing surface the generation of harmful false air flows and thus the emergence of excessive contamination in the region of the cover element is reliably prevented.
- the fastening elements of the channel plate adapter are designed as lugs, which can be acted upon by a multipoint locking arranged on the cover element.
- Such a multi-point lock allows a secure, positive fixing of the channel plate adapter in the receptacle of the lid member.
- Such multi-point locking is particularly advantageous if it is designed as a three-point lock as described in claim 3.
- the multi-point locking has a limited rotatably mounted on the lid member locking ring which is defined in a Kanalplattenadapter- insertion position or in a Kanalplattenadapter- Arret istswolf positionable.
- the locking ring is formed as a cross-sectionally U-shaped component having a rear mounting flange in the installed state and a front mounted clamping flange.
- a fixable on the lid member fixing ring of the locking ring is so movably adjustable that the locking ring on the one hand safely positioned in a set working position on the other hand but also easily between a Kanalplattenadapter- receiving position, which allows the insertion or removal of a channel plate adapter, and a channel plate adapter - Arret istswolf in which an inserted channel plate adapter is set correctly and safely in the recording of the cover element, can be adjusted.
- the locking ring of multipoint locking can be positioned by a locking knob arranged on the knob, for example, in the so-called Kanalplattenadapter receiving position in which the incorporated into the clamping flange recesses are positioned just above the projections of a channel plate adapter located in the recording ,
- the channel plate adapter can be easily removed upwards in this working position of the locking ring. Just as easily a new channel plate adapter can be inserted into the receptacle of the cover element in this working position of the locking ring.
- the channel plate adapter is inserted in such a case with its lugs through the recesses of the locking ring in the multi-point lock. Subsequently, by turning the locking ring into the channel plate adapter locking position, the channel plate adapter is reliably fixed in the receptacle of the cover element.
- the multi-point lock described is a problem-free and quickly detachable, during operation very secure locking device for a channel plate adapter.
- the channel plate adapter in the receptacle of the lid member can also be fixed non-positively.
- Channel plate adapter preferably designed as a permanent magnet inserts, which in bores of the bearing body of the
- each channel plate adapter has at least two such permanent magnet inserts.
- the fastening elements of the channel plate adapter are covered as far as possible during the spinning operation through the front of the channel plate adapter or protected behind the limited by the sealing surface front of the channel plate adapter.
- the channel plate adapter can be easily gripped on the protruding edge of the sealing surface and taken to release the fasteners and / or for removing the channel plate adapter from the receptacle of the cover element.
- the facing in the installed state of the channel plate adapter to the spinning rotor front of the channel plate adapter preferably has a sealing surface, a transition surface and a tower-like attachment. That is, the channel plate adapter has a pneumatically favorable front surface, which ensures that it can lead to either the occurrence of unwanted false air currents or the creation of harmful air turbulence within the rotor housing.
