Description
Technical Field
The invention relates to a combing roller housing for a combing roller of an open-end spinning device, comprising an inlet opening for introducing fiber material into the combing roller housing, an outlet opening for discharging opened single fibers from the combing roller housing, a dirt separation opening for separating impurities from the fiber material, and an inner circumferential wall which surrounds the combing roller during operation and has a fiber-guiding region which extends from the inlet opening through the dirt separation opening to the outlet opening, wherein the combing roller housing comprises a hollow cylindrical ring.
Background
Carding roller housings of various embodiments are already known in the prior art and are used in open-end spinning devices in order to open up a strand of fiber material fed to an opening device into individual fibers and then to feed the opened individual fibers to a spinning device.
DE 32 07 575C2, for example, discloses a carding roller housing which is produced as a cast part, for example, by an injection molding process or a die casting process. The housing is thus made of a relatively soft material. In order to protect the housing wall and to improve the separation of dirt, an insert is therefore provided in the interior of the housing. The insert is made of a foil and is pot-shaped, so that it also forms the rear wall of the combing roller housing. The insert therefore has virtually no fibre-attachable edges, so that the risk of carding roller shell fly (verflukung) is reduced. Furthermore, the insert can be easily replaced.
Another embodiment of a carding roller housing with exchangeable inserts is known from EP 14 550A1. Here, the insert is arranged in the region behind the inlet opening and extends into the region of the dirt separation opening. The inserts form a circumferential wall of the carding roller housing at least partially, but at least in the region of the dirt separation opening. The combing roller housing can thus be adapted in a simple manner to different fibre materials and vibration conditions. The size and position of the dirt separation opening can thus be changed. However, there is a risk of the fibers becoming pinched and collected there at the transition between the insert and the rest of the carding roller housing. Furthermore, different inserts must be prepared and assembled.
Disclosure of Invention
It is therefore an object of the present invention to provide a combing roller housing which can be produced and assembled in a simple manner and which also avoids the combing roller housing from flying.
This object is achieved by a combing roller housing and an open-end spinning device having the features of the independent claims.
A carding roller housing for a carding roller of an open-end spinning device has an inlet opening for introducing fiber material into the carding roller housing, an outlet opening for discharging opened single fibers from the carding roller housing, a dirt separation opening for separating impurities from the fiber material, and an inner circumferential wall which surrounds the carding roller during operation and has a fiber-guiding region which extends from the inlet opening to the outlet opening via the dirt separation opening. The carding roller housing comprises a hollow cylindrical ring.
It is proposed that the hollow cylindrical ring is embodied as a self-supporting member which can be fixed directly at the carrier of the open-end spinning device and comprises an inner circumferential wall with a region for guiding the fibers and comprises an inlet opening, an outlet opening and a dirt separation opening.
In contrast to the prior art, the proposed combing roller housing therefore no longer has additional inserts. In order to adapt to different fiber materials or different spinning conditions, the entire combing roller housing therefore has to be replaced. However, this can be done simply and quickly, since the annular combing roller housing forms the base body of the combing roller housing and can be fixed directly to the carrier. Furthermore, since the annular carding roller housing is reduced to the basic function, i.e. to provide the above-mentioned openings and the regions for guiding the fibers, and has a very compact shape, the carding roller housing can still be produced cost-effectively. Since the annular combing roller housing is embodied in one piece, no gaps are available for the fibers to adhere to. The tendency of the combing roller shell to fly is thus reduced.
It is particularly advantageous if the ring has a fastening opening, in particular a threaded portion, for fastening it on a carrier of the open-end spinning device.
It is particularly advantageous if the ring has a fastening hole, in particular a threaded portion, for fastening it on a carrier of the open-end spinning device. The combing roller housing can thus be fixed in a simple manner on the carrier by means of a screw connection. In this case, a high force transmission can be produced by the screw connection, so that the combing roller housing can be fixed to the carrier almost without play. Thereby further reducing the tendency to fly.
The fastening opening can be embodied as a through-opening, so that the combing roller housing can be assembled from the front side of the spinning device.
However, according to a further embodiment, it can also be advantageous if the fastening bore is embodied as a blind bore, and in particular as a threaded portion. In this case, the fixing may be performed from the rear side of the carrier of the open-end spinning device. In this case, it is advantageous, for example, if the carrier is a pendulum-type housing which can be turned over from the open-end spinning device.
Furthermore, it is advantageous if the fastening bores are arranged at the end face of the ring. The shape of the ring can thus likewise be kept very compact, since no additional fastening webs are required. The carding roller housing can therefore be further held in a play-free manner on the carrier.
Advantageously, the combing roller housing also comprises a plastic cover surrounding the ring. Here, the plastic cover on the one hand creates a visually attractive transition with the carrier of the open-end spinning device. Alternatively, a plastic cover may be used to integrate and/or cover other components, such as the fiber channel insert.
Furthermore, it is advantageous if the fastening bore is arranged at the end face of the ring. The shape of the ring can therefore also be kept non-compact, since no additional fixing webs are required. Therefore, the carding roller shell can be further supported to be fixed at the bearing part without a gap.
Advantageously, the combing roller housing also comprises a plastic cover surrounding the ring. Here, the plastic cover on the one hand creates a visually attractive transition with the carrier of the open-end spinning device. Alternatively, a plastic cover may be used to integrate and/or cover other components, such as the fiber channel insert.
It is also advantageous if the plastic cover is connected to the ring material, in particular injection-molded directly on the hollow cylindrical ring. The carding roller housing is therefore likewise embodied in one piece if different materials are used for the hollow cylindrical ring and the plastic cover. The carding roller housing is closed by the plastic cover without a gap, so that the risk of fibers adhering to the gap is further reduced. The material connection can be achieved in particular by injection molding the plastic cap directly onto the hollow cylindrical ring. However, it is likewise conceivable for the two components to be welded to one another, for example by ultrasonic welding. Furthermore, adhesive bonding is also conceivable.
Advantageously, the ring has one or more form-fitting parts for form-fittingly connecting the plastic lid, wherein preferably the one or more form-fitting parts are arranged at the outer circumferential wall of the ring. Such a form fit can also be advantageous in the case of a material-to-material connection as described above. A positive fit between the hollow-cylindrical ring and the plastic cap is additionally established by means of the positive fit. The plastic cap is thus particularly well fixed to the hollow cylindrical ring. If the form-fitting parts are arranged at the outer circumferential wall of the ring, they are located outside the functional surface or functional area. However, it is also conceivable to arrange the form-fitting part in particular at the front end face of the ring, i.e. the end face pointing outwards in the assembled state of the combing roller housing.
According to another embodiment, it is advantageous if the plastic cover has one or more clip parts for connecting the ring. In this case, the plastic cover is detachably connected to the ring. The clip part is locked in a locking shoulder of the ring, which is formed in accordance with the clip part. This embodiment may provide advantages depending on the manner in which the ring and plastic cap are manufactured. In this case, however, the hollow cylindrical ring likewise forms the base body of the carding roller housing, which carries the plastic cover. The advantage of a simple fastening is thus likewise achieved by this embodiment.
Furthermore, the ring is advantageously made of a metallic material, in particular a steel or aluminum material, and is preferably produced as a casting. By being made of a steel or aluminum material, the hollow cylindrical ring can be made stable and wear-resistant, and therefore the fiber-guiding surface of the combing roller housing can also be formed directly. In this case, by the embodiment as a cast part, it is also possible to achieve a non-perfectly round shape, a shape with projections and to integrate other functions.
Furthermore, the hollow cylindrical ring is advantageously machined. The ring, which is embodied as a cast part, can be simply and precisely machined for post-treatment. In particular, the fiber-guiding surface and, if appropriate, the air-guiding surface can thus be produced with high surface quality and high precision.
It is also advantageous if the inner circumferential wall of the ring is provided with a coating, in particular a wear-resistant coating, at least in the region of the guide fibers. Therefore, the service life of the carding roller shell can be prolonged. Furthermore, the surface quality of the ring as well as the flow and fiber guiding properties can be improved by the coating.
It is particularly advantageous if the ring also has a bypass opening for introducing the intake air flow into the combing roller housing. The bypass opening serves to supply additional air to the combing roller housing, so that less air must be sucked in through the dirt separation opening. Dirt separation can thus be improved in a manner known per se.
In this case, it is advantageous if the ring has a radially outwardly directed projection which has a bypass opening. All functions can thus be integrated in a single stabilizing member.
In this case, it is particularly advantageous if the projection is integral with the ring. The projection can be formed as a casting, for example, in one piece with the ring. By integrally forming the bypass opening and the hollow cylindrical ring, the bypass is also seamlessly formed. The tendency to fly in the bypass is thereby likewise reduced. Alternatively, however, it is also possible that the projection is an additional part which is arranged at the ring.
Furthermore, it is advantageous if the ring has a receiving opening for the fibre channel insert in the region of the outlet opening. The fibre channel insert guides the opened filaments from the combing roller housing to the rotor housing of the spinning device in a manner known per se. Since the receiving openings are arranged directly in the ring, the fibre channel insert is always received in the carding roller housing geometrically precisely.
The advantages mentioned, in particular the cost advantages, as well as the simple assembly and reduced tendency to fly, are likewise achieved in an open-end spinning device with such a carding roller housing, so that protection thereof is also claimed.

Detailed Description
In the following description of the embodiments, identical features or at least similar features in their design and/or mode of action are provided with the same reference numerals. Furthermore, features are only explained in detail at the time of their first introduction, while in the following exemplary embodiments only differences from the already described exemplary embodiments are discussed. Furthermore, for the sake of clarity, only one or only a few of the same components or features are generally labeled.
Fig. 1 shows a schematic side view in partial section of a station 29 of an open-end spinning machine. The station 29 has, in a manner known per se, a combing roller 2 arranged in a combing roller housing 1, for which the strip-shaped fibrous material 5 is fed. In the carding roller housing 1, the fiber material 5 is opened by the carding roller 2 into single fibers 7 and the single fibers are fed to the open-end spinning device 3. The open-end spinning device 3 comprises a spinning rotor 31 arranged in a rotor housing 30 for spinning the fiber material into a yarn and is loaded with a negative pressure via a negative pressure channel 36. The finished thread 32 is finally drawn off by the drawing device 33 and fed to the winding device 34, where it is wound up on a bobbin 35. In the present case, the carding drum housing 1 is arranged on a carrier 13, which is designed as a pendulum housing and at the same time has a cover element (not shown) for the rotor housing 30. The carrier 13 or the oscillating housing can be pivoted in the direction of the arrow in order to release the passage to the rotor housing 30. The carrier 13 is in turn fixed at the frame 25 of the open-end spinning machine.
Fig. 2 now shows a detailed illustration of the open-end spinning device 3 in a schematic sectional side view. Here, it can again be seen in detail that the spinning rotor 31 is arranged in the rotor housing 30 and the carrier 13 is fixed to the machine frame 25. In fig. 2, the carding cylinder housing 1 and the carding cylinder 2 can be seen again better. As can be seen from fig. 2, the carrier 13 has a bearing point 22, in which the combing roller 2 is accommodated. The combing roller housing 1 comprises a hollow cylindrical ring 12, which is designed as a self-supporting component and is fixed directly to a carrier 13 of the open-end spinning device 3. In the present case, the ring 12 is fixed directly at its end face 15 facing the carrier 13. For this purpose, the ring 12 is fixed to the carrier 13 by means of fixing means 26 (for example screws), which are only symbolically shown here by dashed lines. The ring 12 has an inner circumferential wall 10 which, during operation, encloses the carding roller 2 arranged in the carding roller housing 1. Furthermore, the ring has a peripheral wall 18 and a further end face 15 facing away from the carrier 13.
Fig. 3 shows a schematic partially cut-away front view of an open-end spinning device 3 with a combing roller housing 1. The function of the carding cylinder housing 1 and the different functional areas are clearly visible in this figure. The carding roller housing 1 has a feed opening 4 in a manner known per se, through which the fibrous material 5 (see fig. 1) is fed into the carding roller housing 1 by means of a feed roller 20 and is fed to the carding roller 2. The fibrous material 5 is combed by the combing roller 2 rotating in the direction of the arrow (not shown here, only the bearing point 22 is visible here), is loosened there and is conveyed further above the dirt separation opening 8 to the discharge opening 6, where the loosened filaments 7 (see fig. 1) are discharged from the combing roller housing 1 and guided to the spinning rotor 31. As already mentioned in connection with fig. 1, the rotor housing 30 is loaded with a negative pressure, so that the individual fibers 7 can be transported from the outlet opening 6 to the spinning rotor 31 by means of the air flow. The air flow supports the transport of the fibers in the carding roller housing 2.
At the dirt separation opening 8, the impurities 9 combed out of the fibrous material 5 by the carding roller 2 are thrown off the carding roller housing 1 by centrifugal force and can be disposed of. As a result, impurities contained in the fiber material 5 can no longer enter the spinning process and impair the quality of the thread 32 produced (see fig. 1). The dirt separation opening 8 is connected to the ambient air. In the present carding roller housing 1, the inner circumferential wall 10 of the ring 12 of the carding roller housing 1 therefore forms at least in part directly the region in which the fibers are guided. The fiber-guiding region 11 is symbolically indicated by a dotted line and extends from the inlet opening 4 through the dirt separation opening 8 to the outlet opening 6.
The described carding cylinder housing 1 has a self-supporting ring 12 as a main component and therefore has a particularly simple and compact form. The ring 12 is preferably constructed of a metallic material, such as steel or aluminum. Thus, the ring can be manufactured and assembled cost-effectively. As already explained with regard to fig. 2, the self-supporting ring 12 can be fixed directly on the carrier 13 of the open-end spinning device 3 and at the same time has all the main fiber-guiding surfaces in the fiber-guiding region 11. For fastening at the carrier 13, the ring 12 can have fastening holes 14, for example, as shown in fig. 7 and 8. Furthermore, the inlet opening 4, the outlet opening 6 and the dirt separation opening 8 are likewise arranged directly in the self-supporting ring 12. Thus, as in the prior art, there is no need to assemble the carding cylinder housing 1 from a plurality of parts, or to provide the carding cylinder housing 1 with additional inserts. This also contributes to a reduction in the assembly and production expenditure for the carding roller housing 1. Furthermore, by the integral design of the self-supporting ring 12, no gaps are available between the different parts of the carding cylinder housing 1, through which fibers can collect and adhere.
Fig. 4 shows a schematic front view of an open-end spinning device 3 with a combing roller housing 1 with a plastic cover 16. The plastic cover 16 encloses the carding cylinder housing 1 and closes it to the outside, giving a visually appealing appearance, and can also be used for integrating further components or for covering functional parts adjoining the carding cylinder housing 1. The plastic cover 16 shown here extends, for example, into the rotor housing 30, which is not shown here, and provides a good transition to the rotor housing. Furthermore, it can be seen in fig. 4 that, in the present carding roller housing 1, the outlet opening 6 is designed as a receiving opening 24 for a fibre channel insert 27. Such fibre channel inserts 27 are known in the prior art and are usually used for transporting the opened single fibres 7 to the spinning rotor 31. Since in the embodiment shown, the fiber passage insert 27 is accommodated directly in the receiving opening 24 of the ring 12, it is geometrically particularly precisely associated with the combing roller housing 1 and the combing roller 2 rotating therein. The fibre channel insert 27 is here covered for the most part by the plastic cover 16. In this embodiment, the ring 12 is also constructed of a metallic material, such as steel or aluminum. The plastic cover 16 can be injection-molded directly onto the ring 12 in a particularly advantageous manner. In this case, the plastic cover 16 is joined to the ring 12 material. However, the plastic cover 16 may also be connected to the ring 12, for example by ultrasonic bonding or adhesive bonding. However, as described below, such a material connection is also advantageous if the ring 12 additionally has a form-fitting 17 for form-fitting connection with the plastic cover 16. In this case, the plastic cover 16 seals the carding cylinder housing 1 without any gap to the outside.
Fig. 5 shows a sectional illustration in a partial illustration along the section line marked in fig. 4. In this sectional view, it can be seen that the ring 12 has a form fit 17 in the region of its outer circumferential wall 18 in the present case. In addition, the plastic cover 16 is also clearly visible in this sectional view. In this case, according to the first embodiment, it is possible for the plastic cover 16 to be pushed onto the ring 12 only and to cover the ring 12 in the region of the form-fitting 17. For this purpose, the plastic cover 16 must have a certain elasticity. In this case, the plastic cover 16 is fixed to the ring 12 only by means of one or more form-fitting parts 17. Here, a plurality of form-fitting parts 17 can be provided at the circumferential wall 18 of the ring 12 and at the end face 15 facing away from the carrier 13.
However, such a form-fitting connection is particularly advantageous for improving the durability of the connection, in addition to the material connection already described in connection with fig. 4.
Fig. 6 likewise shows a sectional illustration in a partial illustration along the section line indicated in fig. 4, but with an alternative form of connection between the ring 12 and the plastic cover 16. Here, in this example, the plastic cover 16 has two clip portions 19 for connecting the ring 12. In this case, the plastic cover 16 is held purely positively on the ring 12. The clip 19 is arranged at the plastic cover 16 in an elastically yielding manner, so that the plastic cover 16 is not prevented from fitting at the ring 12. In the assembled state, the clip part 19 then interacts with a locking shoulder 28 provided in the ring 12.
Fig. 7 now shows a first embodiment of the ring 12 of the combing roller housing 1 in a schematic front view. In contrast to the embodiment of fig. 3, the combing roller housing 1 or the ring 12 shown here additionally has a bypass opening 21 for introducing an inlet air flow into the combing roller housing 1. The bypass opening 21 restricts the air supply into the carding cylinder housing 1 through the dirt separation opening 8, so that dirt particles contained in the fibrous material 5 to be opened can be better separated. In particular, it is also possible to separate lighter dirt particles which are otherwise entrained by the air flow in the carding roller housing 1 and remain in the fibrous material 5.
Here, the bypass openings 21 are arranged in the projections 23 of the ring 12. The bypass opening 21 is therefore advantageously integrated into the combing roller housing 1 in one piece. As can also be gathered from fig. 7, the ring 12 also has a further projection 23, which delimits the dirt separation opening. In the present ring 12 or carding roller housing 1, therefore, more functions are also combined in a single component, which simplifies the production and assembly. Such a ring 12 can be produced simply as a casting, in particular as an injection molding, for example. Here, the surface in the region 11 of the guide fibers can likewise be additionally treated to achieve a high surface quality and/or provided with a wear-resistant coating, which also applies to all embodiments of the ring 12 shown in the other figures.
Furthermore, in fig. 7, in this example, a total of four fixing holes 14 can also be seen for fixing the ring 12 at the carrier 13 (see fig. 2). Preferably, the fastening hole 14 is embodied as a threaded portion, so that the ring 12 can be screwed directly onto the carrier 13 by means of a plurality of screws. A seamless connection can also be produced here by the contact pressure of the screw.
Fig. 8 now also shows a schematic front view of another embodiment of the ring 12, which ring 12 comprises a protrusion 23 with a bypass opening 21 as shown in fig. 7. In contrast to fig. 7, a form-fitting part 17 is shown at this ring, which is likewise arranged in the region of the peripheral wall 18. As already explained with regard to fig. 5, in addition to the material connection with the plastic cover 16, a form-fitting part can be provided to provide further retention, or as the only connection means with the plastic cover 16.
The invention is not limited to the embodiments shown and described. As any combination of features described, can be modified within the scope of the patent claims even if they are shown and described in the different parts of the description, claims or in different embodiments, without contradicting the teaching of the independent claims.
