Definitions
- the invention relates to an open-end spinning device with an aspirated rotor housing which is open to the front, a spinning rotor which rotates at high speed within the rotor housing and a cover element for closing the rotor housing, an exchangeable cover extension having the mouth region of a fiber guide channel and a thread take-off nozzle being arranged on the cover element .
- OE spinning devices constructed in this way are known, for example, from DE 36 36 182 A1.
- the rotor housing which is open to the front, is closed airtight during the spinning process by a cover element which is fastened to the swivel housing of the spinning device.
- the cover element is screwed from the inside against the swivel housing.
- a sliver opening device with a sliver feed roller, a opening roller and parts of a fiber guide channel is arranged in the swivel housing. The arrangement of the rotating parts is such that they are taken out of operation or braked when the spinning device is opened.
- the cover element During operation, that is to say when the swivel housing is closed and locked in place, the cover element lies against the rotor housing with an annular lip seal and closes this airtight.
- the cover element extends with a cover extension, which, among other things, has the opening area of the fiber guide channel, into the rotating rotor. In this way it is ensured that the mouth area of the fiber guide channel is positioned sufficiently close to the fiber sliding wall of the spinning rotor and the individual fibers transported in the fiber channel are fed to the spinning rotor in accordance with regulations.
- the cover elements also referred to as fiber channel plates, have an outer annular groove for a lip element and a central cover extension.
- a threaded bore for attaching a fiber withdrawal nozzle is arranged in the lid extension.
- the invention is based on the object of developing a cover for a rotor housing which can be manufactured inexpensively and is reliable in operation.
- the sealing surfaces arranged inclined with respect to the direction of installation of the lid extension, in conjunction with axially acting fastening means, offer the advantage that an airtight connection of the fiber channel parts is ensured in the fiber channel transition area.
- the detachable arrangement of the lid extension within the recess of the lid element also offers the advantage that when changing the yarn section or the like, it is not the entire lid element that has to be changed, but only the lid extension.
- a cylindrical pin is provided as a fitting means, which is let into a fitting hole in the cover element, fits into a corresponding fitting hole of the cover extension and thereby ensures the functional installation position of the cover extension. Due to this exact, angularly accurate alignment of the lid extension, it is ensured that within the fiber guide channel, in particular at the transition point from the lid element to the lid extension, there are no approaches which impair fiber transport.
- the lid extension is designed as a rotationally symmetrical component with a rear, conical contact surface.
- Such an embodiment is particularly favorable in terms of production technology.
- the fixing of the lid extension within the receptacle widening in the direction of the rotor housing takes place by means of fastening means which are effective in the axial direction, for example by means of screw bolts. These bolts pass through the cover element from the outside and, when they are turned, pull the corresponding contact surfaces against each other in the area of the fiber guide channel transition, so that there is an airtight contact.
- the lid extension has a central through hole for receiving a thread take-off nozzle.
- An angled threaded hole opens into this through hole, which receives a threaded pin for fixing the thread take-off nozzle.
- An extension opening is preferably provided in the extension of this threaded hole in the area of the cover element. which allows a tool to access the threaded pin. Using a suitable tool, for example a screwdriver, it is possible to change the thread take-off nozzle even when the lid extension is still installed.
- the OE spinning device 1 shown in FIG. 1 has a rotor housing 2 in which a spinning rotor 3 rotates at high speed.
- the spinning rotor 3 is supported on a support disk bearing 4 and is driven by a tangential belt 5.
- the rotor housing 2 which is open at the front, is connected to a suction device 6 and is closed at the front during operation by a cover element 7 which is pivotably mounted about a pivot axis 16.
- the cover element 7 has a sliver opening device 8 an opening roller 9, a sliver feed roller 10, not shown, and part of the fiber guide channel 11.
- the opening roller 9 is preferably driven by a tangential belt 12.
- the sliver feed roller 10 is driven either via a machine-long drive shaft or via an electric individual drive 15.
- the cover element 7 has an annular groove 32 for inserting a lip sealing element 17 and a receptacle 33 which is open in the direction of the rotor housing and has conical contact surfaces 34.
- a cover extension 18 is fixed by means of screw bolts 21, which pass through corresponding through bores in the cover element 7, in fastening bores 30 of the cover extension 18.
- the exact position fixing of the lid extension 18 within the receptacle 33, in particular the angular alignment of the lid extension takes place via a cylindrical pin 26 which, inserted into a fitting bore 35 of the lid element 7, engages in a corresponding fitting bore 25 on the rear side 36 of the lid extension 18.
- the cover extension 18 which is aligned by means of the cylinder pin 26 with its precise angle, lies with its conical contact surface 31 on the correspondingly shaped contact surface 34 of the receptacle 33 and is thereby subjected to a holding force acting in the axial direction via the fastening bolts 21.
- the lid extension 18 also has a central through bore 24 for receiving a thread take-off nozzle 19.
- a threaded bore 27 opens into this through bore 24 at an angle.
- An extension of this threaded bore 27 is In the cover element 7, a connection bore or mounting opening, not shown, is provided, which enables a tool to access a threaded pin 28 arranged in the threaded bore 27. Since the threaded pin 28, which fixes the thread take-off nozzle 19 in the through hole 24, is accessible from the outside, the thread take-off nozzle 19 can also be changed while the cover extension 18 is installed in the cover element 7.
- both the threaded bore 27 and the fiber guide channel section 37 are inserted orthogonally or almost orthogonally into the conical contact surface 31 of the lid extension 18.
