Description
The invention relates to an open-end spinning device for an open-end spinning machine, comprising a spinning rotor which can be driven individually, an individual drive arranged in a drive housing for the spinning rotor, and at least one recess for closing a cover element of the rotor housing in which a rotor of the spinning rotor is accommodated during a spinning operation, wherein the rotor housing is designed as a central support and can be fastened to a machine frame of the open-end spinning machine. The invention also relates to an open-end spinning machine having a plurality of adjacently arranged stations, each station having one such open-end spinning device.
Various structures for fixing an open-end spinning device to a frame of an open-end spinning machine are known.
For example, it is known from DE 42 19 683 A1 to fix individual components of an open-end spinning device directly to a longitudinal support or a longitudinal component of a machine frame of the open-end spinning device. The longitudinal parts give the spinning machine a high rigidity. Since the structural units are directly connected to the longitudinal parts, they remain in position relative to each other for a long period of time. However, the production of the longitudinal parts is correspondingly complicated, since the fastening points, for example fastening holes, of the parts of the open-end spinning device must be introduced very precisely into the longitudinal parts.
According to another concept, it is known to arrange the individual components of the open-end spinning device on a spinning frame and then to fix the spinning frame to the frame of the spinning machine. For example, DE 197 17,737 a1 discloses that the spinning box frame comprises two sides which can be fastened to the machine base and a support arranged between the sides. The side portions are welded to the support. Preferably, a laser welding process is used for this purpose, so that no deformation of the frame due to welding is caused. Thus, fastening holes for components of the open-end spinning device can be made in the individual components of the spinning frame prior to welding. However, the construction of the spinning frame consisting of several parts is complicated.
In order to further reduce the manufacturing and assembly effort in the assembly of the spinning device, designs have also emerged in which the components of the open-end spinning device are fixed to a central support element. For example, DE 101 05 270A1 proposes to arrange the spinning device on a central functional support which can house the components of the open-end spinning device and which is in turn fixed to the frame of the spinning machine.
An embodiment is known from EP 1 664,401 B1, in which the rotor housing of the open-end spinning device forms a central support element which is fixed to the machine base. This means that no additional functional support is required. The other components of the open-end spinning device are then fixed to the rotor housing directly or via other supports.
The object of the invention is to provide an open-end spinning device which can be produced at low cost and which reduces the assembly effort.
This object is achieved by the features of the independent claims.
An open-end spinning device for an open-end spinning machine has a separately drivable spinning rotor, a separate drive arranged in a drive housing for the spinning rotor, and a receptacle for a cover element closing the rotor housing in which a rotor of the spinning rotor is accommodated during a spinning operation. The rotor housing is designed as a central support, which can be fastened to the machine frame of the open-end spinning machine.
It is proposed that the rotor housing is of unitary construction with the drive housing and the at least one receptacle for a cover element.
An open-end spinning machine is also provided, which has a plurality of adjacently arranged stations, each of which has one such open-end spinning device.
The fact that the drive housing is directly constructed in one piece with the rotor housing means that the additional assembly work for fixing the drive housing to the rotor housing can be dispensed with. Furthermore, a correct alignment of the drive device with respect to the axis of the spinning rotor can be achieved without the need for adjustment work. It is particularly advantageous if other functions, such as bearing points of the magnetic bearings, are integrated into the drive housing and/or the rotor housing, since these functions are also precisely aligned with respect to the spinning rotor without the need for adjustment work.
In particular, however, the at least one recess for the cover element is designed in one piece with the rotor housing, which greatly improves the positioning accuracy of the fiber feed channel and the drawing nozzle arranged in the cover element relative to the spinning rotor. Thanks to the integrated design, the machining of the rotor housing, in particular the connection of the stop surface and the fastening point or hole, can be done in one fastening. In this way, an absolute precise position between the component attached to the rotor housing, in particular the cover element with the carding roller, and the spinning rotor can be ensured at all times. This not only simplifies the assembly of the open-end spinning device, but is also particularly advantageous in terms of spinning technology and has a positive effect on the yarn quality.
Advantageously, the rotor housing has a plurality, in particular two, recesses for the cover elements. In this way, the positioning of the cover element and the components arranged thereon, such as the fibre feed channel and the drawing nozzle, with respect to the spinning rotor is again improved. Therefore, hereinafter, we will talk about the vessels in plural. In principle, however, designs with only one recess are also conceivable, such a recess preferably being designed to be wider. The following description of the embodiments and the figures thus also refers explicitly to a rotor housing having only one recess.
It is particularly advantageous if the rotor housing is embodied as a cast part, wherein the rotor housing and the recess for the cover element are integrally cast onto the rotor housing. The rotor housing as a central support element can therefore be produced particularly inexpensively. It is particularly advantageous if the rotor housing is embodied as a die cast part. This makes the manufacture of the rotor housing very accurate. If necessary, the tensioning finishing can be carried out in one fastening, as described previously.
It is also advantageous if the rotor housing has integrally molded fastening means, in particular integrally molded spacer bushings, which serve for fastening to the machine frame. Furthermore, this makes it easier to mount the rotor housing to the housing and ensures a correct positioning of the open-end spinning device with respect to the cross-machine direction.
According to an advantageous development, the rotor housing has a cast frame which comprises receptacles for the cover elements. The rotor housing with the receptacle is thus highly rigid, ensuring accurate positioning between the components even after long-term operation.
It is also advantageous if the drive housing cast onto the rotor housing has at least one bearing point for the magnetic bearing arrangement of the spinning rotor. For example, at least one front bearing point for a front radial bearing of the magnetic bearing arrangement may be integrated into a rotor housing, which constitutes the central support. This will also automatically position the magnetic bearing accurately with respect to the spinning rotor. It is, of course, also conceivable that not only the front bearing point but also the rear bearing point, and possibly also the bearing point of the drive, are integrated in the drive housing cast on the rotor housing.
Furthermore, it is advantageous if the receptacle for the cover element defines a pivot axis and the cover element is accommodated rotatably about the pivot axis in the receptacle of the rotor housing. The rotatable design of the cover element makes it possible to rotate the cover element in a particularly advantageous manner from an operating position closing the rotor housing to a service position allowing access to the rotor housing.
It is also advantageous if the cover element comprises a integrally molded carding roll housing. In this way, the carding roll housing is also automatically positioned accurately with respect to the spinning device or rotor housing. It is therefore particularly advantageous if the carding roll housing is designed in one piece with the cover element.
In order to be able to produce the cover element with the carding roll housing at low cost, it is also advantageous here if the cover element is embodied as a cast part, the carding roll housing being integrally cast on the cover element.
Furthermore, it is also advantageous if the rotor housing has a stop for the cover element, which stop serves to position the cover element in the axial direction of the spinning rotor. In this way, when the cover element is closed, the drawing nozzle housed in the cover element and the rotor of the spinning rotor are automatically correctly positioned with respect to each other.
It is particularly advantageous if the stop is designed to be adjustable, preferably as an adjusting screw. This makes it possible to adjust the correct position of the drawing nozzle with respect to the rotor at all times in terms of spinning technology and to compensate for any tolerances which may exist despite the precise manufacture.
It is also advantageous if the stop is arranged in a region of the rotor housing remote from the recess for the cover element, in particular in the end region of the rotor housing opposite the recess. Thus, the stop is located further from the pivot axis of the cover element, which facilitates adjustment.
According to a further development, it is advantageous if the rotor housing has at least one positioning device for positioning the cover element in the axial direction of the pivot shaft. Thus, during closing, the cover element is automatically brought into the correct transverse position with respect to the pivot axis and is fixed in this correct position when the cover element is closed.
Advantageously, the positioning means are cast directly onto the rotor housing. This means that the positioning device does not require an additional assembly step and always ensures a correct lateral orientation of the cover element with respect to the spinning rotor. Preferably, the positioning device is designed as fork-shaped. Thus, the cover element can be positioned correctly in both axial directions of the oscillating shaft.
Furthermore, it is advantageous if the positioning device has a plastic lining. This may, for example, reduce noise when closing the cover element and ensure a gentle closing when positioning the cover element.
Further advantages of the invention will be described with reference to the following examples. The diagram is:

In the following description of the embodiments, identical features or at least features that are comparable in design and/or operation are given identical reference numerals. Furthermore, these reference numerals are explained in detail only for the first time, and in the following embodiments, only differences from the embodiments already described are referred to. Moreover, for the sake of clarity, only one or a few of the many identical components or features are often indicated.
Fig. 1 shows a schematic front view of an open-end spinning machine 2. In a manner known per se, the open-end spinning machine 2 has a plurality of stations 34 arranged next to one another, which can be arranged on one or both long sides of the open-end spinning machine 2 between two frames 33. In a known manner, each station 34 has a carding roll 9 for opening the fed fibrous material 25 (see fig. 2) into individual fibers and an open-end spinning device 1 for spinning the fibrous material 25 into threads 26. The yarn 26 is then pulled by the pulling device 27 and wound onto the bobbin 29 by the winding device 28. For controlling the processes on the open-end spinning machine 2, the spinning machine also has a control unit 35 which can cooperate with other control units 35 (not shown) provided on the respective stations 34.
Fig. 2 now shows a detailed schematic view of a station 34 of such an open-end spinning machine 2 in a partial sectional side view. As shown in fig. 1, the fiber material 25 is fed into the open-end spinning device 1 and opened into individual fibers by the carding roll 9, from which it is fed into the open-end spinning device 1 through a fiber feed channel (not shown here).
The open-end spinning device generally has a spinning rotor 3, whose rotor 4 rotates in a rotor housing 6, whose rotor shaft 5 is rotatably mounted in a drive housing 7. For this purpose, the spinning rotor 3 is driven by a separate drive 8, which is likewise arranged in the drive housing 7, and is mounted in a magnetic bearing arrangement 16. The magnetic bearing arrangement 16 comprises a front radial bearing 17 and a rear radial bearing 18. The spinning rotor 3 is furthermore supported in the axial direction by an axial bearing 19, which may also be designed as a magnetic bearing, but may also be designed as an air bearing or other bearing. The rotor housing 6 is fixed together with the drive housing 7 to the machine frame 12 of the open-end spinning machine 2.
The rotor housing 6 is subjected to a negative pressure during the spinning operation, for which purpose it is connected to a negative pressure channel 31 via a negative pressure connection 30. During the spinning operation, the rotor housing 6 is closed by a cover element 11, which is here rotatably fixed in the pocket 10 of the open-end spinning device 1 about a pivot 20. To open the rotor housing 6, the cover element 11 can be pivoted from a closed position shown in solid lines to an open position shown in broken lines. The cover element 11 has an extension 36 which supports a yarn drawing nozzle 37, which extends into the rotor 4 of the spinning rotor 3 during the spinning operation. The newly spun yarn 26 is drawn through a yarn drawing nozzle 37. As shown in fig. 5, the extension 36 may also be designed as a replaceable channel plate adapter provided in the cover element 11. In this context, the cover element 11 also carries the carding roller 9, so that the cover element is designed in one piece with the carding roller housing 21.
Fig. 3 now shows a first embodiment of a rotor housing 6 according to the invention. The rotor housing 6 is designed as a central support, which can be fastened to the machine frame 12 (see fig. 2) by fastening means, for example fastening holes 32, and on which other components of the open-end spinning device 2 are arranged. In addition to the housing of the spinning rotor 3 (see fig. 2), the rotor housing 6 also comprises a drive housing 7 and a receptacle 10 for a cover element 11. In this context, the container 10 comprises a hole in which the cover element 11 is rotatably mounted, whereby a pivot 20 for the cover element 11 is formed.
These three components, namely the rotor housing 6, the drive housing 7 and the receptacle 10, are integral with one another. They can therefore advantageously be designed as very compact castings, combining the above functions in one component, and also integrating many other functions or components of the open-end spinning device 1. It is particularly advantageous that all functions and device faces as well as fastening means, such as holes etc., can be introduced in one fastening of the rotor housing 6. In other words, the rotor housing 6 only needs to be fastened once for machining. All processing steps can then be carried out without re-fastening the rotor housing 6. This ensures an extremely precise position of the carding roller housing 21 or of the cover element 11 relative to the rotor housing 6. The rotor housing 6 or the central support can be manufactured at very low cost, since it is designed as a cast part, which, although precisely manufactured, requires only one fastening for the completion of the process. Due to the highly precise positioning of the cover element 11 with the extension 36 and the yarn pulling nozzle 37, considerable technical advantages of spinning are achieved, and high quality yarn can be produced. Due to the integrated design of the rotor housing 6 with the drive housing 7 and the receptacle 10, time-consuming adjustment work of the open-end spinning device 1 can be dispensed with.
Furthermore, in order to assist in the accurate positioning of the cover element 11 relative to the rotor housing 6, a stop 22 may also be provided, as will be explained in more detail below with reference to fig. 5. By means of this stop 22, the cover element 11 can be positioned correctly with respect to the axial direction of the spinning rotor 3 when closed or in the closed position.
Fig. 4 shows another embodiment of a rotor housing 6 according to the invention. In contrast to the rotor housing 6 of fig. 3, the present rotor housing 6 has a cast, encircling frame 14, which comprises the receptacles 10 for the carding roller housing 21 or the cover element 11. The two pockets 10 are connected by a transverse support. Thus, the frame 14 is constituted by two pockets 10 and a transverse support. The rotor housing 6 thus has a particularly high stiffness, which can assist in the accurate positioning of the cover element 11 relative to the rotor housing 6 and the spinning rotor 3.
In the rotor housing 6 of fig. 4, the spacer bush 13 is cast directly onto the rotor housing 6 as fastening means. The spacer bush 13 can be screwed directly onto the vertical wall of the machine frame 12 (see fig. 2). Therefore, the rotor case 6 can be easily connected to the open-end spinning device 1. Of course, such spacer bushings 13 may also be cast onto the rotor housing 6 of fig. 3 in order to correctly position the rotor housing 6 on the machine frame 12.
Furthermore, a positioning device 23 can also be seen on the rotor housing 6 shown here. By means of the positioning means 23, the cover element 11 can be positioned correctly with respect to a direction transverse to the axis of the spinning rotor 3, in this case the weft direction of the rotor housing 6, during closing. In other words, by means of the positioning means 23, the cover element 11 is correctly positioned with respect to the rotor housing 6 in the axial direction of the pivot 20, thereby correctly positioning the spinning rotor 3. As shown herein, the positioning device 23 may comprise only the positioning element 41. This can be achieved, for example, by means of fork-shaped fittings (not shown) on the cover element 11, so that the cover element 11 is positively positioned. In addition, it is also conceivable to provide the second positioning element 41 or the second positioning means 23 at a distance from the illustrated positioning means 23 in order to position the cover element 11 accurately in both axial directions of the pivot 20. Advantageously, the positioning means 23 are cast directly on the rotor housing 6, so that the correct positioning of the cover element 11 is always ensured without any adjustment. The cast-in positioning device 23 also reduces the assembly effort of the rotor housing 6 or the open-end spinning device 1 even further.
Fig. 5 shows an open-end spinning device 1 in a schematic sectional view. In contrast to fig. 3 and 4, the cover element 11 is arranged in the receptacle 10, so that the two parts of the rotor housing 6 and the cover element 11 are shown as cooperating. As already described with respect to fig. 2, the cover element 11 further comprises a carding roller housing 21 which is integrally molded on the cover element 11 and is pivotably mounted on the receptacle 10 of the rotor housing 6, for example by means of a pressure plate 38. Also visible is an extension 36 of the cover element 11, which extension is designed to be insertable into the channel plate adapter of the cover element 11.
Furthermore, according to the present figure, the spinning rotor 3 also shows the working position accommodated in the rotor housing 6. The rotor cup 4 is located in a rotor housing 6, while the rotor shaft 5 is located in a drive housing 7 cast onto the rotor housing 6.
Furthermore, the front radial bearing 17 of the magnetic bearing arrangement 16 can also be seen in this figure. As can be seen from fig. 5, the drive housing 7 and the rotor housing 6 connected thereto have a front bearing point 15 for a front radial bearing 17. For this purpose, fastening holes 32 are provided in the drive housing 7, which enable the front radial bearing 17 to be fastened. According to the figure, the drive housing 7 also has fastening holes 32 which enable the individual drives 8 to be fastened in the drive housing 7. For example, the rear radial bearing 18 (not visible here) may be fastened in a cover element 11 which can be inserted into the drive housing 7. However, it is also possible to fasten the rear radial bearing 18 directly in the drive housing 7.
In the open-end spinning device shown here, a stop 22 for the cover element 11 is furthermore provided. By means of the stop 22, the cover element 11 and the yarn pulling nozzle 37 are correctly positioned with respect to the axis of the spinning rotor 3. In this case, the stop 22 is designed as an adjusting screw which is arranged axially parallel to the axis of the spinning rotor 3. Preferably, as can also be seen from fig. 3 and 4, the stop 22 is arranged in the centre of the open-end spinning device 1, above the axis of the spinning rotor 3.
It is also advantageous if, as shown in the present figure, the stop 22 is provided in the region of the rotor housing 6 remote from the receptacle 10 for the cover element 11. For example, the stop 22 is arranged at an end region 39 of the rotor housing 6 opposite the receptacle 10. Thus, the stop 22 or the adjustment screw is at a large distance from the pivot 20, which facilitates the adjustment of the stop 22. By means of such an adjustable stop 22, the distance between the yarn drawing nozzle 37 and the spinning rotor 3 can be adjusted in different ways, for example to suit the spinning specifications in a particular application.
It is also possible to set the position of the cover element 11 with respect to the rotor housing 6 once after the initial installation of the cover element 11, so that any tolerances that may occur due to the installation of the magnetic bearing arrangement 16 and the installation of the spinning rotor 3 can be taken into account. It is also possible to provide that after the initial adjustment of the stop 22, no further adjustment thereof is to be performed. If the stop 22 is designed as an adjusting screw, the stop can also be fixed, for example, to prevent rotation. It is conceivable here, for example, for the screw to be a locking device or for the screw to be provided with a special head.
To further prevent the stop 22, in this case an adjustment screw, which is adjusted during operation, the adjustment screw may be supported on the rotor housing 6 as shown with an O-ring 40.
Fig. 6 furthermore shows a further embodiment of the positioning device 23 in a schematic top view. In contrast to the positioning device 23 of fig. 4, this positioning device 23 has two opposing positioning elements 41. The positioning device 23 is therefore designed fork-shaped. When the cover element 11 is closed, a corresponding counterpart (not shown) provided on the cover element 11 will pass between the two positioning elements 41, as indicated by the arrows, so that the cover element 11 is positioned accurately again in both axial directions of the pivot shaft 20 (see fig. 3 and 4). Furthermore, the positioning device 23 shown here has a plastic lining 24, which is attached to the positioning elements 41. The positioning of the yarn pulling nozzle 37 relative to the rotor 4 of the spinning rotor 3 is thus further improved.
The invention is not limited to the embodiments shown and described. Variations within the scope of the claims are possible as any combination of the features described, even if these variations are shown and described in the description or in different parts of the claims or in different embodiments, provided that they do not contradict the teaching of the independent claims.
