Description
Technical Field
The present invention relates to a circular comb for a combing machine and a combing head (comb head) having such a circular comb.
Background
These types of circular combs are used in combers to cause a supplied mass of fibers (cotton, wool, etc.) to be combed out (combing out), wherein the mass of fibers may be provided in the form of a roll wound onto a tube or in the form of individual clusters of fibers. In recent years, the comber nip (comb nip) rate (number of combers/min) has been greatly increased, which also results in an increase in productivity, but also increases the mechanical stress on the circular comb carrier.
In practice, a circular comb for a combing machine consists of a circular comb carrier which is provided with a clamping hub with which the circular comb carrier is fastened in a rotationally fixed manner to a driven circular comb shaft. A card clothing carrier containing a card clothing which causes the end of a mass of fibers (also called a cluster of fibers) supplied by a nipper unit to be combed out is attached to a part of the circumference of the circular comb carrier. In an alternative embodiment, a circular comb carrier is used, which is mounted directly on the driven circular comb shaft.
The demands imposed on such circular combs have increased; for example, higher precision of the components requires that the combing action be precisely coordinated with the fibrous material to be combed. Because of these requirements, the adjustment options for the circular combs within the combing head must be improved. In particular, an accurate setting of the distance between the envelope circle of the card clothing and the circular comb axis contributes to an improved combing process. By such an adjustment, the distance between the lower nipper of the nipper and the enveloping circle of the comb card clothing of the circular comb can be set to ensure optimal combing. Such adjustability through the use of arcuate spacer elements is illustrated and described in DE 297 20 656 U1, for example. However, for such arcuate elements, precise adjustment is not possible with incremental dimensions as low as minimum. If the arcuate spacer element disclosed in DE 297 20 656 U1 is replaced with another arcuate spacer element having a different thickness, for example to change the envelope circle radius of the comb card clothing of a circular comb, the outer radius of the spacer element protruding in the direction of the carrier is thus changed, while the inner radius of the carrier (in the case of a carrier, on which it rests) remains constant. Thus, a tensioning may be caused between the carrier and the spacer element.
EP 0,514,319 A1 discloses different versions of circular combs with spacer elements. According to the disclosure of EP 0,514,319 A1, a wedge can be used as a spacer element, whereby the wedge is secured against falling in the axial direction by means of a stop screw. A disadvantage of the disclosed design is that positioning the wedge by moving the wedge in the axial direction is complicated and must therefore be performed in the disassembled state of the circular comb. When the attachment of the circular comb segments is released, the previously set anchor point of the wedge is lost again, as the wedge on the roller body is free to move in the axial direction.
Furthermore, EP 2,789,716 A1 discloses a circular comb with a carrier provided with an inner section protruding towards the shaft and having a recess which is open in the direction towards the shaft and extends in the longitudinal direction of the hollow profile and in which a support element is accommodated, which support element is supported on the one hand via a first support surface on the base surface of the recess and on the other hand via a second support surface on the outer circumference of the shaft. A replaceable spacer element is disposed between the support element and the base surface of the recess. The aim is to allow the radius of the envelope circle of the comb card clothing to be set precisely by simply inserting a precise spacer element between the base body and the support element. However, it is disadvantageous that, depending on the spacer element present, the distance between the lower clamping plate of the clamp and the envelope circle of the comb card clothing of the circular comb can only be adjusted in a stepwise manner. In addition, in order to readjust the distance, the circular comb must be removed from the combing apparatus to allow for replacement of the spacer element.
Disclosure of Invention
It is therefore an object of the present invention to provide a circular comb which allows for continuously adjusting the distance between the lower nipper of the nipper and the envelope circle of the comb card clothing of the circular comb, wherein the adjustment amount can be changed without removing the circular comb.
This object is achieved by means of a device having the features of the independent claims.
A circular comb for a combing machine is proposed, wherein the circular comb has a combing card clothing and a circular comb axis together with a card clothing carrier and at least one circular comb carrier. The card clothing carrier is mounted on the circular comb carrier. At least two adjusting devices are arranged between the card clothing carrier and the circular comb carrier in the respective end regions of the card clothing carrier, said adjusting devices being used for adjusting the distance between the card clothing carrier and the circular comb carrier. As a result of the connection of the lower nipper of the nipper to the circular comb shaft, the distance between the lower nipper of the nipper and the enveloping circle of the comb card clothing also changes when the distance between the circular comb carrier and the card clothing carrier is adjusted.
The card clothing carrier has a card clothing support surface on its side facing away from the circular comb shaft. The comb card clothing is attached to the clothing support surface via suitable means, for example with screws or by welding or adhesive bonding. A comb card clothing consisting of a separate wire strip mounted on a clothing support surface is used, or a comb card clothing consisting of a pre-made comb element mounted on a clothing support surface is also used. The card clothing support surface is positioned in a circular segment shape around the circular comb axis.
As is known from the prior art, the circular comb carrier can be provided as a disk having a length, which is viewed in the direction of the circular comb axis. The length of the circular comb carrier corresponds to only a portion of the circular comb length, wherein a plurality of such short circular comb carriers are used for fastening the comb card clothing. The use of a plurality of circular comb carriers for the comb card clothing has the following disadvantages: it is difficult to orient the circular comb carrier in order to achieve a concentric arrangement of the comb card clothing or card clothing carrier with respect to the circular comb shaft. The length of the circular comb carrier thus advantageously corresponds to the length of the circular comb. This has the following additional advantage: the circular comb together with the comb card clothing can be pre-installed before being installed in the combing machine.
The card clothing carrier is advantageously fastened to the circular comb carrier in its respective end region, viewed in the direction of the circular comb axis, via at least two detachable connecting elements. Screws have proven suitable as connecting elements. As a result of the high demands on the connection of the card clothing carrier to the circular comb carrier due to the acceleration forces that occur, it has proven suitable to screw the card clothing carrier to the circular comb carrier after adjustment.
After the release of the connecting element for fastening the card clothing carrier to the comb carrier, the distance between the lower clamping plate and the enveloping circle of the comb card clothing positioned on the card clothing carrier can be easily adjusted via the adjusting device without having to remove the comb from the comb head when changing the setting. In the mounted state, the setting can therefore also be checked directly by measuring the distance between the lower nipper and the envelope circle of the comb card clothing positioned on the carrier. For this purpose, the circular comb in the mounted state can be rotated into a measuring position in which the distance can be set and measured. After the setting has been performed, the card clothing carrier can be fixed by simply tensioning the connecting elements for fastening it to the circular comb carrier.
The distance between the circular comb carrier and the card clothing carrier can be adjusted in various known ways, for example with set screws or eccentric screws. According to the invention, between the card clothing carrier and the circular comb carrier, the adjusting means advantageously comprise a plate wedge (flat wedge) positioned in the end region of the circular comb, starting from the respective end of the card clothing carrier in the direction of the longitudinal axis of the circular comb shaft, which plate wedge has a continuous cross-section tapering directed towards the card clothing carrier or the circular comb carrier. As a result of this cross-section tapering, the distance between the card clothing carrier and the circular comb is changed when the plate wedge is moved in the direction of the circular comb axis.
The continuous cross-section tapering is provided by a bevel of the surface of the plate wedge facing the card clothing carrier, the wedge angle of the bevel being 6 degrees or less. By selecting a wedge angle smaller than 6 degrees, self-locking of the plate wedge is ensured. Thus, the plate wedge is kept in place when the connecting element of the card clothing carrier is tensioned onto the circular comb carrier.
Furthermore, it is advantageous if the respective connecting element of the card clothing carrier together with the circular comb carrier extends through an opening provided in a particular plate wedge. As a result, the card clothing carrier is not only fixed on the circular comb carrier, but at the same time the plate wedge is clamped firmly between the card clothing carrier and the circular comb carrier at the location of the cross-section tapering. In addition, passing the connecting element through the opening in the plate wedge prevents the plate wedge from slipping out at the sides during adjustment.
The contact surface of the plate wedge facing the circular comb carrier is advantageously integrally formed on a support surface provided on the circular comb carrier. The play-free contact of the plate wedge with the surface of the circular comb carrier is achieved by matching the shape of the circular comb carrier and the card clothing carrier (corodinate) at their contact locations. In addition, by incorporating contours (e.g., longitudinal grooves), it is an option to achieve guided displacement of the plate wedge along the circular comb axis.
Advantageously, the card clothing carrier has a mating surface which corresponds to the bevel of the plate wedge and has the same wedge angle. The maximum self-locking effect of the two inclined surfaces occurs when the flat support is arranged between the card clothing carrier and the plate wedge.
The particular plate wedge is preferably provided with an adjusting screw engaging the cavity of the card clothing carrier, which adjusting screw is positioned with its axis parallel to the circular comb axis. As a result of the provision of the cavity, the adjusting means can be positioned between the card clothing carrier and the circular comb carrier without significantly weakening the card clothing carrier itself. This is also beneficial for the aerodynamic behaviour of the circular comb during its movement compared to arranging the adjusting means outside the card clothing carrier. In addition, due to the axially parallel arrangement of the adjusting screws, the plate wedge on the end face side can be adjusted from outside the circular comb, and the circular comb or parts thereof do not have to be removed for adjustment.
Furthermore, the adjusting screw is preferably mounted in the card clothing carrier so as to be rotatable in its axial position, and the female thread is provided in a plate wedge, wherein the plate wedge is adjustable in its position in the direction of the circular comb axis relative to the card clothing carrier by: the set screw is engaged with the female thread in the plate wedge by rotating the set screw. Since the axial position of the adjusting screw does not change even during rotation due to the axial fixation, the plate wedge is axially displaced relative to the circular comb axis according to the pitch of the thread via the adjusting screw which is screwed (thread) into engagement with the female thread of the plate wedge. Both the card clothing carrier and the circular comb carrier do not change their axial position, as a result of which the card clothing carrier and the circular comb carrier are driven radially apart or brought together as a result of the displacement of the plate wedge.
Preferably, a holding device for the adjustment screw is provided for rotatable holding in the cavity of the card clothing carrier. This results in the entire adjusting device being arranged in the card clothing carrier. The retaining means is particularly preferably a circlip. Alternatively, a suitable shape of the cavity and the adjustment screw may be provided to achieve axial retention of the adjustment screw. The insertion of the circlip is an easy to install economical design for holding the adjusting screw in its axial position.
The opening in the plate wedge is advantageously designed as a slot which opens out towards the side facing away from the end of the card clothing carrier. Such a design allows easy replacement of the plate wedge without completely separating the card clothing carrier from the circular comb carrier. The design of the groove also prevents the plate wedge from slipping out at the sides during adjustment after loosening the connecting element.
The distance between the card clothing carrier and the circular comb carrier is advantageously 0mm to 1.5mm. It has been shown that by using plate wedges, it is possible to achieve an adjustability of the distance within this range, and that this adjustability is also sufficient for the necessary adjustment of the distance between the lower nipper of the nipper and the envelope circle of the comb card clothing for the fibre material to be processed in the combing facility.
The direction of rotation of the circular comb produces a feed side, which is the portion of the comb card clothing that first meets the fibre clusters to be combed. The circular comb moves through the fibre tufts as a result of its rotation until it leaves the fibre tufts on the discharge side of the comb card clothing. The card clothing is usually positioned concentrically with its envelope circle relative to the circular comb shaft. However, it has been shown that the distance between the card clothing carrier and the circular comb carrier on the feed side of the comb card clothing advantageously differs from the distance between the card clothing carrier and the circular comb carrier on the discharge side of the comb card clothing by 0.1mm to 1.5mm, due to the flow conditions caused by the movement of the circular comb. Since it is an option to set the distance on the feed side and on the discharge side in different ways, the combing process can be optimally matched to the requirements imposed by the fibre material to be combed.
Furthermore, it is advantageous if the counterweight (compensating weight) is mounted non-rotatably on the circular comb shaft via the fastening element independently of the circular comb carrier. Thus, the circular comb carrier can be replaced without having to also remove the counterweight from the circular comb shaft. This is particularly advantageous when pre-mounted circular combs that are pre-conditioned to accommodate a particular combing process are used. The assembly kit, once set, can be easily replaced and comprises the circular comb carrier, the card clothing carrier, the adjusting device and the comb card clothing.
A comb head is also proposed, which has a circular comb with a card clothing carrier with a card clothing support surface and with at least one circular comb carrier, and which is opposite to the position of the counter weight or balancing element on the circular comb shaft and to which the card clothing carrier is fastened via a connecting element, wherein the circular comb is designed according to the description above.

Detailed Description
Fig. 1 shows a schematic side view of a combing head 1 of a combing machine according to the prior art. In the known combing machine, for example, eight such combing heads 1 are positioned adjacent to one another. The combing head 1, of which only a part of the elements is illustrated, has a clamping unit which is supported in the frame of the combing machine and can be rotated back and forth via swivel arms 3 and 4 about a clamping shaft 5 and a circular comb axis 6. The clamp shaft 5 is driven by a driver (not shown in more detail) to impart reciprocating motion to the clamp unit. A circular comb shaft 8 is positioned in the circular comb axis 6, to which circular comb 7 is non-rotatably fastened. The circular comb shaft 8 is likewise driven continuously or discontinuously together with its circular comb axis 6 by a drive (not shown) in the direction of rotation 23. In the known method shown, the circular comb 7 fastened to the circular comb shaft 8 below the clamping unit is formed of two circular comb carriers 9 which are fixedly fastened to the circular comb shaft 6 at a distance from each other in the direction of the circular comb axis 6 and on their outer circumference are fastened on the one hand card clothing carriers 10 and on the other hand counterweights 11. As schematically illustrated, the fastening of the counterweight 11 takes place via screws 12, by means of which the counterweight 11 is attached to the circular comb carrier 9. The card clothing carrier 10 is likewise fixedly connected to the circular comb carrier 9 via a schematically illustrated connecting element 24. The comb card clothing 13 is fastened above a card clothing carrier 10 which, like the counterweight 11, extends over the entire length L of the circular comb 7 (see fig. 4). In the known combing machine, the circumferential angle of the combing clothing 13 (also referred to as combing angle) is approximately 90 degrees.
The clamp unit is formed by a clamp frame 14 to which a lower clamp plate 15 and an upper clamp plate 16 are fastened. In the embodiment shown, the nipper unit is closed, wherein the fibre tufts 17 protruding from the nip point of the nipper unit are caught by the comb card clothing 13 and combed out. This combing out process is basically determined by the distance C between the lower nipper 15 and the envelope circle 40 of the comb card clothing 13. Also in the clamp frame 14, a feed roller 18 is rotatably supported above the lower clamp plate 15, which feed roller is driven in a stepwise manner by a ratchet drive (not shown). A lap 19 (or individual fibre clusters) supplied to the combing device 1 is fed via this feed roller 18 to the nip point of the nipper unit. After the combing operation of the fiber bundle 17 is completed, the nipper unit is rotated in the direction of the subsequent separation roller pair 20. During this rotation operation, the nipper unit is opened and the combed end of the lap 19 or the fibre tuft 17 is laid onto the end of the previously formed fibre fleece 21 and is joined (holder) to this end by the nip point of the separating roller 20 and is carried away in the conveying direction 22.
Fig. 2 shows a schematic illustration of two embodiments of a circular comb according to the invention in longitudinal section. The circular comb is shown as having a length L along the circular comb axis 6, wherein the length L corresponds to the commonly used extension of the combing device. The circular comb axis 6 is at the same time the longitudinal axis of a circular comb shaft 8, on which the circular comb is mounted non-rotatably via a circular comb carrier 9 or 30. The card clothing carrier 10 has a card clothing support surface 44 on the side facing away from the circular comb carrier 9 or 30. A comb card clothing in the form of a separate card wire or comb element is mounted (not shown) on the clothing support surface 44. However, as shown in the left embodiment, it is possible that the length M of the circular comb carrier 9 is shortened, since the card clothing support surface 44 does not absolutely have to extend over the entire length L. However, the length M of the circular comb carrier 30 advantageously corresponds to the length L of the circular comb, as shown in the right embodiment. If the circular comb carrier 30 is guided over the entire length L of the circular comb, it has proven to be suitable in practice to design the circular comb carrier 30 as a hollow profile.
The left half of fig. 2 shows an embodiment of a circular comb with a circular comb carrier 9 and a card clothing carrier 10. The circular comb carrier 9 has a length M and is present in a plurality, seen over the entire length L, i.e. at both respective ends of the card clothing carrier 10. In the embodiment shown, the circular comb carrier 9 is composed of two half-shells which are fastened to the circular comb shaft 8 via tensioning screws 25. Spring wedges 45 are inserted for non-rotatably mounting the circular comb carrier 9 on the circular comb shaft 8. However, other torsion protection means are conceivable, such as locking pins. The card clothing carrier 10 is fastened to the respective circular comb carrier 9 via the connecting element 24. The adjusting means 27 are inserted in the end region 26 of the card clothing carrier 10 between the card clothing carrier 10 and the circular comb carrier 9. The adjusting means 27 are used for adjusting the distance a between the card clothing carrier 10 and the circular comb carrier 9. The counterweight 11 is fastened to the circular comb carrier 9 via screws 12 on the opposite side of the circular comb carrier 9 from the card clothing carrier 10. The rotation of the circular comb shaft 8 is achieved using the counterweight 11, which rotation is practically free from unbalance, despite the presence of the comb card clothing on one side. Thus, the counterweight 11 has a length corresponding to the card wiring 10.
The right half of fig. 2 shows an embodiment of a circular comb with a circular comb carrier 30 and a card clothing carrier 10. The circular comb carrier 30 has a length L and extends throughout the entire length L of the circular comb. In the embodiment shown, the circular comb carrier 30 is designed to extend over the length L and is tensioned to the profile of the circular comb shaft 8 via a fastening screw 31. In order to non-rotatably mount the circular comb carrier 30 on the circular comb shaft 8, a fastening screw 31 is guided through the circular comb shaft 8. The card clothing carrier 10 is fastened to the circular comb carrier 30 via the connecting element 24. The adjusting means 27 are inserted in the end region 26 of the card clothing carrier 10 between the card clothing carrier 10 and the circular comb carrier 30. The adjusting means 27 are used for adjusting the distance a between the card clothing carrier 10 and the circular comb carrier 30. The balancing member 28 is fastened to the circular comb shaft 8 via a fastening member 29 on the opposite side of the circular comb shaft 8 from the card clothing carrier 10. The balancing element 28 is used to achieve a rotation of the circular comb shaft 8, which is practically free from unbalance, despite the presence of the comb card clothing on one side.
Fig. 3 shows an enlarged schematic illustration of an embodiment of the adjusting device 27 according to the invention according to fig. 2. The adjusting means 27 are interposed between the card clothing carrier 10 and the circular comb carrier 9 and comprise plate wedges 32 and adjusting screws 38. The contact surface 34 of the plate wedge 32 facing the comb carrier 9 rests on the support surface 35 of the comb carrier 9. The contact surface 34 of the plate wedge 32 is adapted to the shape of the support surface 35 of the circular comb carrier 9, so that a play-free combination of the plate wedge 32 and the circular comb carrier 9 is possible.
The plate wedge 32 has an L-shaped design, wherein the first leg points radially from the circular comb carrier 9 towards the card clothing carrier 10 and the second leg engages between the circular comb carrier 9 and the card clothing carrier 10 in the direction of the circular comb axis 6. The second leg of the plate wedge 32, which engages between the circular comb carrier 9 and the card clothing carrier 10, is provided with a bevel 36 on the side facing the card clothing carrier 10, so that the effective cross section of the plate wedge 32 between the circular comb carrier 9 and the card clothing carrier 10 tapers continuously in the direction of the circular comb axis 6 starting from the end 33 of the card clothing carrier 10. In addition, the mating surface 37 of the card clothing carrier 10 facing the plate wedge 32 is provided with a slope corresponding to the cross-sectional tapered portion of the plate wedge 32, thereby having a wedge angle. If the axial position of the plate wedge 32 is now changed in the direction of the circular comb axis 6, the circular comb carrier 9 and the card clothing carrier 10 are moved towards each other in the radial direction, whereby the distance a between the circular comb carrier 9 and the card clothing carrier 10 is changed. The position of the plate wedge 32 can be changed until the card clothing carrier 10 rests on the circular comb carrier 9 and the distance a becomes zero.
In addition, the card clothing carrier 10 is fastened to the circular comb carrier 9 via the connecting element 24. The connecting element 24 engages through an opening 43 in the plate wedge 32, wherein the opening 43 is large enough that it is not directly held by the connecting element 24 in any possible position of the plate wedge 32. The plate wedge 32 is clamped between the circular comb carrier 9 and the card clothing carrier 10 by tensioning the connecting element 24 and is thus fixed in its position at that time.
To adjust the axial position of the plate wedge 32, a female thread 39 (which is positioned axially parallel to the circular comb axis 6) is provided in the first leg of the plate wedge 32 and is likewise inserted with an adjusting screw 38 having its axis 42 parallel to the circular comb axis 6 engaged with the female thread. The adjusting screw 38 engages with a cavity 40 in the clothing carrier 10 provided for this purpose. Within the cavity 40, a retaining means 41 (e.g. a circlip) is provided for fixing the adjusting screw 38 in its axial position with respect to the card wire carrier 10 and thus also with respect to the circular comb carrier 9. When the adjusting screw 38 is rotated, the axial position of the plate wedge 32 is changed with respect to the comb carrier 9 and the card clothing carrier 10, due to the axial fixation of the adjusting screw 38.
Fig. 4 shows a schematic illustration of a first embodiment of a circular comb at a viewing angle X according to fig. 2. The circular comb basically comprises a circular comb carrier 9, a card clothing carrier 10 and a comb card clothing (not shown) fastened to the card clothing carrier. The circular comb carrier 9 is formed as two half-shells which are mutually tensioned on the circular comb shaft 8 via tensioning screws 25. Spring wedges 45 are provided for non-rotatably mounting the circular comb carrier 9 on the circular comb shaft 8. The card clothing carrier 10 is fastened to the circular comb carrier 9 via the connecting element 24 and has a card clothing support surface 44 on the side opposite the circular comb carrier 9. The card clothing support surface 44 is positioned concentrically with respect to the circular comb shaft 8 about the circular comb axis 6. The counterweight 11 is fastened to the circular comb carrier 9 via screws 12 on the opposite side of the circular comb carrier 9 from the card clothing carrier 10. In addition, an adjusting device according to fig. 3 is inserted between the circular comb carrier 9 and the card clothing carrier 10. These adjusting means are designed in the form of plate wedges 32 cooperating with adjusting screws 38 (see fig. 3) and serve to set the distance a between the circular comb carrier 9 and the card clothing carrier 10 on the feed side 46 of the circular comb and the distance B between the circular comb carrier 9 and the card clothing carrier 10 on the discharge side 47 of the circular comb. The feed side 46 refers to the part of the card clothing or card clothing carrier 10 which first meets the fibre bundle to be combed, depending on the direction of rotation 23, i.e. at the front as seen in the direction of rotation 23. The combing process can be influenced via different settings of the distances a and B.
Fig. 5 shows a schematic illustration of a second embodiment of a circular comb at a viewing angle Y according to fig. 2. The circular comb basically comprises a circular comb carrier 30, a card clothing carrier 10 and a comb card clothing (not shown) fastened to the card clothing carrier. The balancing element 28 is positioned on the opposite side of the circular comb carrier 30 from the card clothing carrier 10 and is fastened to the circular comb shaft 8 with a fastening element 29. The circular comb carrier 30 together with the balancing elements 28 is tensioned to the circular comb shaft 8 via fastening screws 31 extending through the circular comb shaft 8. The card clothing carrier 10 is fastened to the circular comb carrier 30 via the connecting element 24 and has a card clothing support surface 44 on the side opposite the circular comb carrier 30. The card clothing support surface 44 is positioned concentrically with respect to the circular comb shaft 8 about the circular comb axis 6. In addition, an adjusting device according to fig. 3 is inserted between the circular comb carrier 30 and the card clothing carrier 10. These adjusting means are designed in the form of plate wedges 32 cooperating with adjusting screws 38 (see fig. 3) and serve to set the distance a between the circular comb carrier 9 and the card clothing carrier 10 on the feed side 46 of the circular comb and the distance B between the circular comb carrier 9 and the card clothing carrier 10 on the discharge side 47 of the circular comb. The feed side 46 refers to the part of the card clothing or card clothing carrier 10 which first meets the fibre bundle to be combed, depending on the direction of rotation 23, i.e. at the front as seen in the direction of rotation 23. The combing process can be influenced via different settings of the distances a and B.
The invention is not limited to the exemplary embodiments shown and described. Modifications and combinations of features are possible within the scope of the patent claims, even if the features are illustrated and described in different exemplary embodiments.
