Circular comb for carding machine

Abstract

The present invention describes a circular comb (6) for a carding machine for combing textile fibers, which is adapted to be mounted on a carding machine shaft that can rotate about an axis (W). The circular comb (6) has a body (15) that carries a combing set (17) and a weight compensation element (16) that is attached to the shaft (5) by rotational engagement on the side of the shaft (5) opposite the combing set (17). After mounting on the carding machine, an adjustable support mechanism (30) exists between the body (15) and the weight compensation element (16), and the body (15) and the weight compensation element (16) are in direct contact with each other in several regions, allowing the body (15) and the weight compensation element (16) to change their positions relative to each other perpendicular to the axis (W), thereby adjusting the position of the combing tip (33) of the combing set (17).

Description

[Technical Field]

[0001] This patent application claims priority from German patent application DE 102022210530.3, the contents of which are incorporated herein by reference. [Background technology]

[0002] The present invention relates to a circular comb for a carding machine for carding textile fibers, intended to be mounted on a carding shaft rotatable about its axis.

[0003] Circular combs for use in carding machines are known from prior public use. A combing set is arranged on the body of the circular comb and engages with the tufts of textile fibers to be combed. The combing set is arranged along at least a portion of the circumference of the outer part of the body, thereby defining an active combing area. The combing result is determined by the combing distance between the combing envelope curve of the circular comb of the combing set, along which the combing set advances, and the upper nipper lip of the nipper device. To set the desired combing distance, it is known to displace the body together with the combing set in a position perpendicular to its axis.

[0004] In order to adjust the body and the combing set, for example, Patent Document 1 intends to install an insert rail between the body and the shaft, and the distance between the insert rail and the body can be changed by a flat wedge.

[0005] From DE 10 200 04 143 A1 a circular comb is known in which replaceable spacer elements can be installed between the support element and the body.

[0006] Although known solutions in principle make it possible to adjust the position of the comb tip, they have the disadvantage that the relative arrangement of several different parts between the body and the shaft, such as support elements and spacer elements, is required, which complicates the position adjustment and is prone to errors. The stability of the circular comb is also impaired by the different parts supporting each other. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] EP3754055A1 [Patent Document 2] EP2789716A1 Summary of the Invention [Problem to be solved by the invention]

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to improve the positioning of the comb tips of circular combs, and in particular to provide a stable circular comb that allows for easy and precise adjustment of the position of the comb tips. [Means for solving the problem]

[0009] This object is achieved by a circular comb having the features of claim 1. The circular comb according to the invention comprises a main body carrying a combing set on its outer arc-shaped outer portion and a weight compensation element configured to be attached to the shaft by rotational engagement on the side of the shaft opposite the combing set, as viewed in the radial direction of the shaft. The central idea of ​​the invention is an adjustable support mechanism present between the main body and the weight compensation element when attached to the carding machine. The support mechanism is configured so that the main body and the weight compensation element are in direct contact with each other in several areas and can change their positions relative to each other perpendicular to the axis, thereby adjusting the position of the combing tips of the combing set. The support mechanism combines the adjustable position of the combing tips with stable support of the main body to the weight compensation element due to direct contact. This improves the stability of the circular comb. In particular, the main body is in direct, preferably positive, contact with the counterweight of the weight compensation element. No additional support elements are required. The circular comb has a simple and stable structure. This increases the operational reliability of the carding machine, in particular ensuring reliable operation even at high carding machine operating speeds.

[0010] Direct contact between the body and the weight compensation element also has the advantage of easy and accurate orientation of the body and the combing elements arranged thereon relative to the axis: unintentional tilting or twisting of the combing set relative to the axis is reduced and in particular prevented.

[0011] The support mechanism in particular simplifies the assembly of the circular comb onto the shaft: the body is removable in a simple manner, for example for cleaning and / or replacing the combing set.

[0012] The combing set in particular has a plurality of tangentially arranged combing bars in succession in the circumferential direction, which together cover a circumferential angular segment for combing and define a combing area of ​​the circular comb, which may be received and fixed, in particular releasably fixed, for example in corresponding comb recesses in the body.

[0013] The body of the circular comb may be, for example, a one-piece body. It may also be made of multiple parts. In order to achieve high stability and simultaneously reduced weight, the body may have, for example, a lattice structure.

[0014] The weight compensation element is attached to the shaft in a rotationally engaged manner. For example, the weight compensation element may be fixed to the shaft using a clamping screw passing through the shaft. The clamping screw is preferably screwed into the counterweight body on the opposite side of the shaft. This ensures that the weight compensation element is securely fixed to the shaft in a rotationally engaged manner. Additionally or alternatively, the weight compensation element may be fastened to the shaft using a bracket that surrounds the shaft. For example, the bracket may be pressed into a corresponding recess in the weight compensation element, in particular into the counterweight body of the weight compensation element, using a pressure element.

[0015] The position and orientation specifications used relate in particular to the axis of rotation of the shaft, also called the axis. The axis defines a cylindrical coordinate system. Thus, "axial" means an orientation in the direction of the axis, "radial" means an orientation perpendicular to the axis, and "tangential" means an orientation in the circumferential direction around the axis. The combing direction of a circular comb is in particular the rotational direction in which the circular comb rotates together with the shaft around the axis. It is in particular one of the two circumferential directions of the axis.

[0016] Textile fibres here are in particular wool fibres, cotton fibres, synthetic fibres, chemical fibres or fibres consisting of a mixture of at least two of the above fibre types.

[0017] Advantageous configurations of the circular comb according to the invention emerge from the features of the claims dependent on claim 1 .

[0018] In one advantageous configuration, the adjustable support mechanism is configured for linear movement, particularly translation, of the body relative to the weight compensation element. The support mechanism is particularly preferably configured for linear movement, particularly translation, of the body relative to the weight compensation element in a direction oriented perpendicular to the axis. For example, the body may be movable, particularly translatable, along a direction extending radially relative to the axis on the opposite side of the axis from the weight compensation element. The linear movement allows for simple and effective adjustment of the position of the combing tip, particularly the combing envelope along which the combing tip advances.

[0019] Preferably, the linear movement, in particular the translation, of the body relative to the weight compensation element is guided. For example, surface areas of the body or the weight compensation element that are in direct contact may translate (move in parallel) relative to each other during the linear movement. This ensures smooth and accurate linear movement in one direction while simultaneously fixing the relative position in other spatial directions.

[0020] In one advantageous configuration, the adjustable support mechanism is configured to set different relative positions between the body and the weight compensation element perpendicular to the axis from the second axial end to the first axial end. This makes it possible to set the longitudinal inclination of the body required to match any corresponding longitudinal inclination of the upper nipper lip. Circular combs are particularly flexible and can be precisely adapted to the relevant application, in particular to the relevant carding machine. A specific combing distance can be precisely and easily set over the entire length of the base comb in the axial direction.

[0021] In one advantageous configuration, the adjustable support mechanism is configured for pivotal movement of the main body relative to the weight compensation element, in particular around a pivot axis extending parallel to the axis and offset laterally from the axis. The pivotal movement allows for smooth and easy adjustment of the relative position of the main body and the weight compensation element. The pivot axis is advantageously arranged parallel to the axis and offset laterally from it. This results in a particularly effective change in the distance of the comb tip from the axis during pivoting. The extension of the pivot axis parallel to the axis has the advantage that the change in position of the comb tip relative to the axis occurs evenly over the entire length of the circular comb in the direction of the axis.

[0022] In one advantageous configuration, the body rests only on the weight compensation element during assembly. There is no direct connection between the body and the axis. This has the advantage that the body only needs to be oriented relative to the weight compensation element during assembly. Loosening of the clamping element between the body and the axis is prevented. Assembly is easy and error-resistant. Circular combs are structurally simple and durable.

[0023] In one advantageous configuration, the weight compensation element has at least one contact surface that contacts the shaft in the assembled state. The contact surface between the weight compensation element and the shaft provides high stability. The weight compensation element can be securely and fixedly attached to the shaft, which does not prevent easy removal and installation of the main body.

[0024] In one advantageous configuration, the main body has an inner portion facing the shaft, which, together with the inner recess wall, defines a recess, and in the assembled state, there is a gap between the inner wall of the recess of the main body and the shaft. The gap defines the distance of the main body from the shaft. This particularly simply ensures that the main body is supported only by the weight compensation element. The gap also reduces the weight of the circular comb, particularly the main body. This allows reliable and efficient operation of the carding machine, even at particularly high operating speeds.

[0025] The inner wall of the recess has an inner wall radius, which is defined as the smallest radial distance between the axis and the inner wall of the recess. The inner wall radius is, for example, 124% to 250% of the axis radius, and in particular 155% to 210% of the axis radius. For example, the inner wall radius is approximately 206%, approximately 177%, or approximately 155% of the axis radius. Examples of axis radii are 15 mm, 17.5 mm, 20 mm, 22.5 mm, or 25 mm. The inner wall radius in the assembled state may be selected to be, for example, approximately 31 mm or approximately 36 mm.

[0026] The gap has a gap radius between the outer surface of the shaft and the inner wall of the recess in the assembled state. The gap radius is defined as the smallest radial distance between the inner wall of the recess and the outer surface of the shaft. The gap radius is, for example, 24% to 150% of the shaft radius of the carding machine shaft, in particular 55% to 110% of the shaft radius.

[0027] In one advantageous configuration, the weight compensation element is at least partially received in the recess in the assembled state. Receiving the weight compensation element at least partially in the recess ensures a compact and stable configuration of the circular comb. The weight compensation element may preferably contact a small area of ​​the inner wall of the recess to ensure a secure and stable support of the main body.

[0028] In one advantageous configuration, the body, as part of the support mechanism, has at least two fixing surfaces extending parallel to the axis, and in the assembled state, the body is in direct, positive contact with the weight compensation element in the area of ​​the fixing surfaces, so that the body is oriented in the direction of the axis and fixed together with the coaming set mounted on the body. The body is particularly preferably oriented parallel to the axis as a result of the direct contact of the weight compensation element in the area of ​​the fixing surfaces. The at least two fixing surfaces ensure stable and reliable support of the body on the weight compensation element. Unintentional tilting or rotation of the body relative to the weight compensation element, especially in the circumferential direction, is prevented, which simplifies assembly and reduces the risk of errors.

[0029] The fixing surface may for example abut, in particular flatly, against a corresponding counter-fixing surface of the weight compensation element, in particular a counterweight body of the weight compensation element. The fixing surface and the counter-fixing surface may in particular be partially (in multiple areas) movable relative to each other in order to allow a guided movement of the body relative to the weight compensation element.

[0030] In one advantageous configuration, at least two of the fixing surfaces are flat. The flat fixing surfaces simplify linear movement, particularly translation, of the main body relative to the weight compensation element to adjust the position of the comb tip. Furthermore, a large contact area between the main body and the weight compensation element is ensured, thereby providing a particularly stable bearing of the main body on the weight compensation element.

[0031] In one advantageous configuration of the circular comb, at least two of the fixing surfaces are curved, particularly differently curved, in a plane defined perpendicular to the axis. The curved course of the at least two fixing surfaces allows the body to be easily rotated and guided relative to the weight compensation element. Positive contact between the body and the weight compensation element is not hindered by the rotation. Particularly preferably, the weight compensation element has a plurality of correspondingly curved opposing fixing surfaces to ensure direct surface contact, particularly regardless of the rotation position.

[0032] The different curvatures of the at least two fixing surfaces in a plane defined perpendicular to the axis also have the advantage that assembling the body in an unintended orientation is prevented, which makes assembly easier and increases operational reliability.

[0033] In one advantageous configuration of the circular comb, the at least two fixing surfaces have the same axis in a plane defined perpendicular to the axis. The shared axis may particularly define a pivot axis for relative pivotal movement between the main body and the weight compensation element. This allows the main body to pivot particularly smoothly and accurately relative to the weight compensation element. The shared axis is preferably offset laterally from the axis in a plane defined perpendicular to the axis. This allows a particularly simple and effective adjustment of the position of the comb tip by pivoting the main body relative to the weight compensation element.

[0034] In one advantageous configuration of the circular comb, the support mechanism has releasable fastening means for clamping and fixing a variable position between the main body and the weight compensation element. For example, the releasable fastening means may be formed by fastening a screw that can be screwed into a corresponding hole in the weight compensation element. Particularly preferably, the releasable fastening means, in particular a fastening screw, is guided through a recess, in particular a slot, formed in the main body in the assembled state. For example, the releasable fastening means may be threaded through a corresponding recess, in particular a slot, in the region of the fixing surface of the main body. A clamping force is then applied to the region of the fixing surface. This allows for secure fixation over a wide range. The slot allows for easy, in particular guided, positioning of the main body relative to the weight compensation element when the fastening means is released. The slot allows for flexible adjustment of the relative position between the main body and the weight compensation element.

[0035] Particularly preferably, the releasable clamping means, in particular the clamping screw, is oriented so that the clamping force is oblique, preferably substantially perpendicular, to the adjustment direction in which the position of the body relative to the weight compensation element is adjusted, which ensures that the positioning of the body relative to the weight compensation element is not impaired by the clamping force.

[0036] In one advantageous configuration of the circular comb, the support mechanism has orientation means that ensure the desired relative orientation of the body and the weight compensation element in the assembled state. This reliably prevents assembly in the wrong orientation. For example, the orientation means may be provided by at least two fixing surfaces that extend with different curvatures in a plane defined perpendicular to the axis. Additionally or alternatively, the orientation means may also have releasable fastening means that are arranged offset from one another on different sides of the body and the weight compensation element in the circumferential direction, in particular offset from one another in the axial direction.

[0037] In one advantageous configuration of the circular comb, the support mechanism has a hanging means on the main body and a counter-hanging means on the weight compensation element for suspending the main body on the weight compensation element during assembly. This simplifies assembly. The main body does not need to be held by hand during assembly. This also increases the accuracy of setting the position of the comb tip. Hanging and counter-hanging means in the form of bayonet slits or bayonet projections have proven particularly suitable. This allows the main body to be easily suspended on the weight compensation element without the use of tools. Preferably, the relative positions of the main body and the weight compensation element can be at least roughly predetermined by the bayonet lock formed in this way. This simplifies assembly.

[0038] In a particularly advantageous configuration, the suspension means on the main body and the counter-suspending means on the weight compensation element are associated with variable positioning of the main body and the weight compensation element relative to each other. For example, by changing the position of the suspension means and / or the counter-suspending means, the main body can be at least pre-positioned, preferably accurately positioned, relative to the weight compensation element. For example, the suspension means can be dimensioned such that the counter-suspending means is held therein without play. In particular, the insertion slot can be dimensioned such that the insertion protrusion is held therein without play. By adjusting the position of the suspension means and / or the counter-suspending means, the main body is correspondingly moved relative to the weight compensation element.

[0039] In a particularly suitable configuration, the bayonet projections may be formed, for example, as part of the eccentric shaft. The position of the bayonet projections can be changed by rotating the eccentric shaft. It is particularly preferred to arrange an eccentric shaft with a bayonet projection at each axial end of the circular comb. Arranging the eccentric shafts in or on the weight compensation element has proven to be particularly suitable.

[0040] A particularly preferred configuration allows for simple application of force to adjust the suspension means and / or counter-suspension means. For example, the eccentric shaft can be rotated by applying force using an eccentric adjustment screw. The eccentric adjustment screw can engage with an operating surface of the eccentric shaft at a position offset from the central longitudinal axis of the eccentric shaft. It is particularly advantageous if the eccentric shaft is biased against the force applied by the eccentric adjustment screw. This allows the eccentric shaft to be easily reset when the eccentric adjustment screw is returned to its original position. Additionally or alternatively, the rotation angle of the eccentric shaft can be limited by a limiting element. This prevents the eccentric shaft from twisting, thereby preventing the position of the weight compensation element relative to the main body from changing beyond a certain adjustment range. For example, a fixed limiting element can protrude into a limiting holder provided on the eccentric shaft. The maximum rotation angle is then defined by stop surfaces of the limiting holder that are located on opposite sides of the eccentric shaft in the circumferential direction.

[0041] In one advantageous configuration, the support mechanism has adjustment means for adjusting the variable relative position between the main body and the weight compensation element. This allows particularly easy and precise adjustment of the relative position of the main body and the weight compensation element. There is no need to hold the main body by hand while adjusting the relative position. The circular comb is easy to install and reliable in operation. It is particularly preferred that suitable adjustment means are present in the region of each of the axial ends of the circular comb.

[0042] Suitable adjustment means can be formed, for example, by adjustable suspension means and / or counter-suspension means as described above. Particularly suitable suspension means can be, for example, the aforementioned plug lugs, which are particularly preferably arranged on the eccentric shaft together with corresponding eccentric adjustment means.

[0043] Alternatively or additionally, the adjustment means may also have a plurality of adjustment screws. The adjustment screws may, for example, be screwable into the main body or the weight compensation element and rest on the other of these parts. For example, an adjustment screw may be provided at each axial end of the circular comb. The adjustment screws are easily accessible and operable at the axial ends. For example, the adjustment screws may be screwed into the weight compensation element and rest on the main body, in particular on the end cover of the main body. This ensures that sufficient force can be applied to adjust the position. As a result of the adjustment means, the position of the main body relative to the weight compensation element is preferably fixed using releasable fastening means, so that no permanent force application is required.

DETAILED DESCRIPTION OF THE INVENTION

[0046] Mutually corresponding parts are provided with the same reference numerals in Figures 1 to 9. The details of the exemplary embodiments described in more detail below may also constitute the invention in their own right or form part of the subject matter of the invention.

[0047] Figure 1 shows an embodiment of a carding machine 1 for carding textile fibres. The carding machine is only shown diagrammatically in Figure 1. It comprises a nipper device 2, a take-off device 3, brushes 4 and a circular comb 6 mounted on a shaft 5.

[0048] The nipper device 2 is used to supply the textile fibres to be combed. It comprises an upper nipper 7 and a lower nipper 8. The upper nipper 7 and the lower nipper 8 can be opened and closed during the combing cycle (=comb play), and are shown in the closed state in Figure 1. In addition, during the combing cycle, the nipper device 2 performs a relative movement with respect to the other machine parts of the carding machine 1, in particular with respect to the take-off device 3 and its fixed take-off rollers 9, 10, 11 and 12. The relative movement is produced by rotation about the nipper axis 13 by means of a transmission.

[0049] The take-off rollers 9, 10, 11 and 12 of the take-off device 3 are arranged in pairs and have the function of collecting and removing the textile fibers after combing.

[0050] A circular comb 6 is provided for combing the textile fibers. An upper nipper lip 14 is formed at the end of the upper nipper 7 facing the circular comb 6. The upper nipper lip 14 cooperates with the circular comb 6 for combing the textile fibers. Optionally, a fixed comb (not shown) may be provided, attached to a fixed comb holder 52 of the nipper device 2.

[0051] The circular comb 6 is only shown diagrammatically in FIG. 1 . It comprises a body 15 and a weight compensation element 16. The weight compensation element 16 is attached to the shaft 5 in a rotationally engaged manner. The body 15 is supported by the weight compensation element 16. A combing set 17 is arranged along the outer portion of the arc-shaped body 15. The combing set 17 comprises several combing bars 18 arranged circumferentially on the body 15 around the axis W of the shaft 5. In the illustrated embodiment, the combing set 17 comprises six combing bars 18. The combing bars 18 collectively cover a combing circumference angle segment that defines the combing range of the circular comb 6. The combing circumference range may be, for example, between 75° and 150°.

[0052] When the carding machine 1 is in operation, the shaft 5 is driven in rotation about the axis W, in particular at a discontinuous angular speed, which causes the circular comb 6 to rotate via a weight compensation element 16 attached to the shaft 5 by rotational engagement. The carding machine 1 is operated at a high comb cycle speed of the shaft 5 and thus of the circular comb 6 (for example 600 revolutions / minute).

[0053] The axis W extends in the longitudinal direction of the circular comb 6. The axis W may in particular also be understood as the central longitudinal axis of the circular comb 6. A cylindrical coordinate system is defined with respect to the axis W, with an axial direction z along the axis W, a radial direction r pointing in the direction of the distance from the axis W, and a tangential direction φ pointing in the circumferential direction around the axis W. A plane corresponding to the plane of the drawing in FIG. 1, hereinafter also referred to as the vertical plane N, is defined perpendicular to the axis W. In the cylindrical coordinate system, the vertical plane N is spanned by the radial direction r and the circumferential direction φ.

[0054] When the circular comb 6 is driven in rotation via the shaft 5, it, in particular its combing set 17, moves along a combing envelope 19. The combing envelope 19 is circular in the vertical plane N and has a combing radius R corresponding to the maximum radial distance of the combing tip 33 of the combing set 17 from the axis W. The minimum distance between the upper nipper lip 14 and the combing set 17, in particular its combing tip 33, is also referred to as the combing distance d. The correct positioning of the combing tip 33 of the combing set 17 relative to the upper nipper lip 14, and therefore the combing distance d, are important parameters for the operation of the carding machine 1. For precise adjustment of the combing distance d, the position of the combing tip 33 of the combing set 17 is adjustable. For this purpose, the position of the body 15 relative to the weight compensation element 16 is changeable perpendicular to the axis W. The relative position is adjustable so that the maximum radial distance of the combing tip 33 from the axis W, and therefore the combing radius R, is changeable.

[0055] A first embodiment of the circular comb 6, in particular the body 15 and the weight compensation element 16 and their relative mobility, will now be described in detail in connection with FIGS.

[0056] The weight compensation element 16 has a counterweight body 20. A plurality of brackets 22 are attached to the counterweight body 20 by a plurality of pressure pieces 21. In the assembled state, the shaft 5 is clamped between the brackets 22 and the weight compensation element 16 so that the weight compensation element 16 is attached to the shaft 5 by rotational engagement. In addition to or instead of the brackets 22, the weight compensation element 16, in particular its counterweight body 20, may be screwed to the shaft.

[0057] A recess 50 having an arcuate cross section is formed in the counterweight body 20 for partially receiving the shaft 5. The recess 50 forms a contact surface 51 of the weight compensation element 16 for direct contact with the shaft 5 in the assembled state.

[0058] The body 15 has a number of comb receptacles 23 in which the comb bars 18 are received and locked in a known manner. The body 15 does not have a solid structure, but rather a lattice structure made of a number of lattice posts 24. The lattice structure ensures that the body 15 is rigid but at the same time lightweight. To reduce the ingress of dirt into the lattice structure and in particular into the comb receptacles 23, when the circular comb 6 is assembled, there are a number of end covers 25 which are held in corresponding receptacles 27 of the body 15 by screws 26.

[0059] Body 15 has an arcuate cross section in a vertical plane N perpendicular to axis W. The inner portion of body 15, which faces shaft 5 during assembly, defines a recess 28 having an inner recessed wall 29. After assembly onto shaft 5, a gap is formed between shaft 5 and inner recessed wall 29. Radially, the gap has a gap diameter F. Gap diameter F is defined as the smallest radial distance between inner recessed wall 29 and the outer surface of shaft 5.

[0060] The shaft 5, the bracket 22 and at least partially the weight compensation element 16 are received in the recess 28 during assembly. The body 15 does not directly contact the shaft 5 during assembly, in particular the body is not directly connected or attached to the shaft 5.

[0061] When assembled, the main body 15 rests solely on the weight compensation element 16. For this purpose, a support mechanism 30, which will be described in detail below, is formed between the main body 15 and the weight compensation element 16.

[0062] The support mechanism 30 provides direct, positive contact between the body 15 and the weight compensation element 16. For this purpose, the body 15 has two fixing surfaces 31 extending parallel to the axis W. The fixing surfaces 31 are flat and are part of the inner concave wall 29. In the assembled state, the fixing surfaces 31 form-fit against flat, opposing fixing surfaces 32 of the weight compensation element 16, which also extend parallel to the axis W. The opposing fixing surfaces 32 are configured as the outer surfaces of the counterweight body 20. As a result of the form-constrained contact between the fixing surfaces 31 and 32, the body 15 with the combing sets 17 mounted thereon is oriented and fixed in the direction of the axis W during assembly. Torsion of the body 15 relative to the weight compensation element 16 in a direction perpendicular to the flat fixing surfaces 31 is prevented. At the same time, the flat configuration of the fixed surface 31 and the counter-fixed surface 32 allows linear displacement of the body 15 relative to the weight compensation element 16 to change their relative positions and adjust the position of the combing tip 33 .

[0063] The body 15 is linearly movable relative to the weight compensation element 16 perpendicular to the axis W. The movement occurs in a direction perpendicular to the axis W and perpendicular to the surface normal of the fixed surface 31.

[0064] In the assembled state, the main body 15 and the weight compensation element 16 are fastened together using releasable fastening means in the form of a plurality of fastening screws 34. The fastening screws 34 pass through a plurality of through-slots 35 formed in the main body 15 and screw into a plurality of holes in the counterweight body 20 of the weight compensation element 16. The fastening screws 34 fasten the main body 15 to the weight compensation element 16 via the fixed surface 31 or the counter-fixed surface 32. As a result, a clamping force acts in a direction normal to the surface of the fixed surface 31 or the counter-fixed surface 32. This allows the clamping force to be applied over a wide range. In addition, the clamping force acts perpendicular to the direction of movement of the main body 15 relative to the weight compensation element 16. Therefore, the linear movement, and therefore the adjustment of the position of the comb tip 33, can be precisely adjusted and is not affected by the clamping force.

[0065] The holes in the counterweight body 20 and the corresponding slots 35 in the main body 15 for receiving the clamping screws 34 are arranged in pairs opposite each other in the circumferential direction φ. Opposing holes and slots 35 are at the same axial position along the z direction or axis W. In other embodiments (not shown), the opposing clamping screws and slots may have an offset, particularly in the direction of axis W. This breaks the symmetry of the releasable clamping means. The main body and the weight compensation element can be connected in a predetermined relative orientation. This prevents incorrect installation of the circular comb 6, particularly with respect to the orientation of the comb tips relative to the combing direction, i.e., with respect to the rotational direction of the shaft. This break in symmetry forms an orientation means that ensures the desired relative orientation of the main body and the weight compensation element during assembly. Other orientation means, particularly breaks in symmetry, are also conceivable. For example, flat fixed and counter fixed surfaces facing each other in the vertical plane N may not extend parallel to each other, so that only one fixed surface is suitable for form-constrained contact with one of the counter fixed surfaces.

[0066] The configuration of the slots 35 allows for the position of the body 15 to be changed relative to the weight compensation element 16. To change the relative position, the clamping screws 34 can be loosened and the body 15 can be brought to a desired position relative to the weight compensation element 16. Once in the desired relative position, the clamping screws 34 can be tightened again to secure the body 15 to the weight compensation element 16 by clamping.

[0067] In principle, the linear movement of the body 15 relative to the weight compensation element 16, and therefore relative to the axis 5, can be performed manually by loosening the clamping screws 34 and lifting the body 15 into the corresponding position. For example, the body 15 can be manually pressed against a gauge band inserted between the comb tip 33 and the upper nipper lip 14. To simplify the movement and to precisely adjust the position of the comb tip 33, the support mechanism 30 of the circular comb 6 has adjustment means 36 for adjusting the variable relative position between the body 15 and the weight compensation element 16.

[0068] The adjustment means 36 has an eccentric shaft 37 inserted into the counterweight body 20 of the weight compensation element 16. The adjustment means 36 has two eccentric shafts 37 assigned to each end face of the weight compensation element 16. The eccentric shafts 37 are inserted into the counterweight body 20 so that the central longitudinal axis E of the eccentric shaft extends perpendicular to the axis W and perpendicular to the opposite fixed surface 32. The central longitudinal axis E of the eccentric shaft extends in the width direction of the weight compensation element 16.

[0069] Each eccentric shaft central longitudinal axis E has a plurality of bayonet projections 38 at each end thereof, each eccentrically disposed relative to the eccentric shaft central longitudinal axis E. Opposite bayonet projections 38 each have the same offset from the eccentric shaft central longitudinal axis E.

[0070] The plug-in projections 38 pass through a plurality of through-holes 39 in the counter-fixing surface 32 on the side of the counterweight body 20 and protrude laterally beyond them. The plug-in projections 38 cooperate with plug-in slits 40 in the main body 15. The plug-in projections 38 and the plug-in slits 40 form a plug-in lock, by which the main body 15 can be suspended from the weight compensation element 16. The plug-in slits 40 function as a suspension means, and the plug-in projections 38 function as a counter-suspension means for the support mechanism 30. This simplifies assembly. There is no need to hold the main body by hand, even when the clamping screws 34 are unscrewed.

[0071] When the eccentric shaft 37 rotates, the position of the plug lug 38 changes in a plane parallel to the counter-fixture surface 32. The movement of the plug lug 38 has a component parallel to the axis W and a component perpendicular to the axis W. The component of movement perpendicular to the axis W is relevant to setting the position of the body 15 relative to the weight compensation element 16. The plug slot is therefore dimensioned in a direction perpendicular to the axis, so that the plug lug 38 is held in the plug slot 40 without play in this direction. The component of movement parallel to the axis W is compensated for by a corresponding longitudinal extension of the plug slot 40.

[0072] When the eccentric shaft 37 rotates, a component of movement perpendicular to the axis W of the plug projection 38 is transmitted to the body 15 via the plug slot 40. The plug projection 18 and the plug slot 40, and therefore the corresponding suspension or counter-suspension means of the support mechanism 30, are responsible for variable positioning of the body 15 and its weight compensation element 16 relative to one another. The corresponding eccentric arrangement of the plug projections 38 at opposite ends of the eccentric shaft 37 also ensures that opposite sides of the body 15 in the circumferential direction φ are moved equally relative to the weight compensation element 16. This reliably prevents wedging and / or tilting of the body 15.

[0073] The operation of the eccentric shaft 37 is described below: The eccentric shaft 37 has two grooves, which are arranged on its outer surface and offset in the longitudinal direction E of the eccentric shaft, and whose bottoms form an operating surface 41 and a counter-operating surface 42, respectively.

[0074] An eccentric adjustment screw 43 engages the actuation surface 41 on one side of the eccentric shaft central longitudinal direction E. By threading the eccentric adjustment screw 43, an adjustment force is applied to the actuation surface 41. As a result of the application of a force on one side, threading the eccentric adjustment screw 43 causes the eccentric shaft 37 to twist.

[0075] The eccentric adjustment screw 43 of each eccentric shaft 37 protrudes from an end face of the weight compensation element 16. The eccentric adjustment screws 43 are easily accessible and can be actuated to cause rotation of the eccentric shaft 37. Each eccentric adjustment screw 43 is protected from unintentional actuation by a lock nut 44.

[0076] A counter force is applied by a pressure piece 45 on one side of the eccentric shaft central longitudinal axis E. For this purpose, the pressure piece 45 is biased against the counter working surface 42 by a compression spring 46. The compression spring 46 is supported by a threaded bolt 47. The bias force, and therefore the counter force, can be adjusted by screwing or unscrewing the threaded bolt 47.

[0077] The operating surface 41 and the counter operating surface 42 are parallel to each other. The eccentric adjusting screw 43 and the pressure piece 45 engage with opposite sides of the operating surface 41 and the counter operating surface 42, respectively, with respect to the eccentric shaft central longitudinal axis E. Therefore, the reaction force generated by the pressure piece 45 counteracts (weakens) the adjusting force generated by the eccentric adjusting screw 43. Therefore, the reaction force causes the eccentric shaft to rotate in a direction opposite to the direction of rotation caused by screwing in the eccentric adjusting screw 43. When the eccentric adjusting screw 43 is screwed in, the reaction force must be overcome in order to rotate the eccentric shaft. When the eccentric adjusting screw 43 is unscrewed, the reaction force causes the eccentric shaft 37 to rotate back.

[0078] The outer surface of the eccentric shaft 37 is also formed with limiting recesses with limiting stops 48 located opposite each other in the circumferential direction of the eccentric shaft 37. Limiting elements in the form of limiting screws 49 engage in the limiting recesses between the limiting stops 48. The limiting stops 48 interact with the limiting screws 49 and determine the maximum rotation angle α of the eccentric shaft 37.

[0079] The adjustment means 36 allows the relative position of the body 15 and the weight compensation element 16 to be accurately set in a simple manner by operating the eccentric adjustment screw 43. Once the desired relative position is set, it can be fixed by tightening the clamping screw 34. The adjustment means 36 can be adjusted independently of each other at opposite axial ends of the circular comb, defined in the direction of the axis W. Thus, the adjustable support mechanism 30 is configured to set different relative positions between the body 15 and the weight compensation element 16 perpendicular to the axis W from a second axial end opposite the first axial end in the direction of the axis W to the first axial end as seen from the axis W. Consequently, the intended combing distance d can be set accurately and precisely, regardless of any possible longitudinal inclination of the upper nipper lip 14. The combing radius R can vary along the axis W.

[0080] Further embodiments of the weight compensation element 116 will now be described with reference to Figures 11 to 13. The weight compensation element 116 may for example be combined with the body 15 of the previous embodiment to form a circular comb.

[0081] The weight compensation element 116 has a counterweight body 120. The counterweight body 120 is substantially the same as the counterweight body 20 of the weight compensation element 16 of the previous embodiment. The difference, particularly as can be seen from the partial cross-sectional view in FIG. 13, is that the limiting screw 49 that limits the rotation of the eccentric shaft is threaded at its end face. The partial cross-section corresponds to the cross-sectional planes s1 and s2 shown in FIG. 12. The cross-sectional plane s1 is at the same height as the limiting screw 49, and the cross-sectional plane s2 is at the same height as a plurality of spring pressure pieces 61 having external threads. Each of the spring pressure pieces 61 is threaded into a corresponding hole 62 and reacts to the adjustment force of the respective adjustment screw 43.

[0082] To attach the weight compensation element 116, a plurality of clamping screws 63 are threaded from below through corresponding holes in the counterweight body 120 and the shaft. The clamping screws 63 are configured as cylindrical threads. The clamping screws 63 are screwed into a counterholder 64. The counterholder 64 extends parallel to the axis and, in the assembled state, is located on the opposite side of the axis from the weight compensation element 116. The counterholder 64 is connected to the weight compensation element 116 via the clamping screws 63.

[0083] FIG. 14 shows a further embodiment of a circular comb 206. The circular comb 206 corresponds to the circular comb 6 described above in connection with FIGS. 2 to 10 in the configuration of the main body 15 and the weight compensation element 16. The circular comb 206 differs from the circular comb 6 only in the configuration of the support mechanism 230. The support mechanism 230 of the circular comb 206 has an eccentric shaft 37, but does not have an eccentric adjustment screw or a pressure piece acting against the screw. The eccentric shaft 37 extends freely within the support mechanism 230, apart from a rotation angle limit. The main body 15 can be lifted to adjust its position relative to the weight compensation element 16. In response to the lift, the eccentric shaft 37 is rotated to bring the bayonet projections 38 to the corresponding positions. Therefore, the eccentric shaft 37 and the bayonet projections 38 arranged thereon are only involved in setting the relative position, insofar as they provide additional guidance for the main body 15. Additionally, for assembly, the body 15 can be suspended by means of a suspension means configured as a plug slit 40 to a counter suspension means formed by the plug protrusion 38 .

[0084] A further embodiment of the circular comb 306 will be described with reference to FIG. 15. The circular comb 306 differs from the previously described circular comb 206 in the configuration of the support mechanism 330. The insert slots 340, which serve as the suspension means for the main body 315, are dimensioned so that the insert projections 338 are received therein with play. This allows the main body 315 to be suspended from the weight compensation element 316 without the need to adjust their relative position by rotating the insert projections 338. Therefore, in the embodiment of FIG. 15, the insert projections 338 do not need to be mounted on a corresponding eccentric shaft, but can be formed, for example, directly on the counter-fixing surface 332. This simplifies the structure of the support mechanism. For linear movement of the main body relative to the weight compensation element, the main body can be lifted into the correct position with the clamping screws loosened.

[0085] In a variation of the embodiment of FIG. 15, the bayonet projection 338 may be mounted on a rotatably mounted eccentric shaft to ensure proper relative positioning regardless of the width of the bayonet slit 340 .

[0086] A further embodiment of circular comb 406 will be described with reference to Figure 16. Circular comb 406 differs from the multiple circular combs previously described in that support mechanism 430 does not have a suspension means on body 415 and does not have a counter-suspension means on weight compensation element 416 to suspend body 415 during assembly. During assembly, body 415 is held by hand and moved to a desired target position relative to weight compensation element 416. At the desired position, clamping screws 34 are threaded through slots into weight compensation element 416 to establish fixation of body 415 by clamping.

[0087] A further embodiment of the circular comb 506 will be described with reference to FIG. 17 . The circular comb 506 has a support mechanism 530 with adjustment means 536 for adjusting the position of the weight compensation element 516 and the body 515. The adjustment means 536 each include an adjustment screw 65 threaded through a corresponding hole in the counterweight body 520 in the region of the axial end of the weight compensation element 516 and screwed thereto. The screw 65 can be actuated from the underside of the counterweight body 520 on the opposite side of the shaft 5. The threaded tip 66 of the screw 65 rests on a stop edge 67 of the end cover 25. The cover 25 and the body 515 attached thereto can be raised or lowered by screwing in or loosening the adjustment screw 65. This makes it possible to set a desired relative position of the body 515 and the weight compensation element 516; in particular, different relative positions can be set at each of the axial ends. The adjustment screw 65 is a structurally simple and effective adjustment means 536. For clamping fixation, the clamping screw 34 is tightened after the desired relative position is reached. The circular comb 506 may otherwise correspond to the circular combs described above. The adjusting screw 65 may be combined in particular with the previously described embodiments of the circular comb, and in particular with the circular combs 206, 306, and 406 shown in Figures 14 to 16.

[0088] A further embodiment of the circular comb 606 will be described with reference to Fig. 18. The support mechanism 630 of the circular comb 606 has adjustment means 636 in the form of adjustment screws 665. The adjustment screws 665 are screwed from above into corresponding holes in the weight compensation element 616 at each axial end. The screw heads 68 of the adjustment screws 665 bear against the support edges 67 of the respective end covers 25. The screw heads 68 are accessible from the end faces and can be actuated. By screwing or loosening the adjustment screws 665, the cover 25 and therefore the body 615 can be lowered or raised relative to the weight compensation element 616.

[0089] In the partial cross-sectional view of FIG. 18, the weight compensation element 616 also shows a plurality of holes 69 into which the clamping screws 34 are threaded for clamping fixation.

[0090] In other embodiments, the adjustment means has only one adjustment screw arranged at one of the axial ends. In still other embodiments, the at least one adjustment screw, in particular operable from the underside of the weight compensation element, may be arranged at any position along the axis. The at least one adjustment screw may be supported on at least one corresponding support edge of the body, which may be formed, for example, on the inner wall of the recess.

[0091] A further embodiment of the circular comb 706 will be described with reference to Figures 19-21. A support mechanism 730 of the circular comb is configured for pivotal movement of the main body 715 relative to the weight compensation element 716. A joint extension 70 is disposed on the counterweight body 720 of the weight compensation element 716. In a plane perpendicular to the axis W, the joint extension 70 has a substantially circular cross-section terminating in a connecting web 71 connecting the joint extension 70 to the counterweight body 720. The joint extension 70 extends parallel to the axis W with a constant cross-section. A joint receiving portion 72 extending along the axis W is formed in the main body 715. The inner contour of the joint receiving portion 72 corresponds to the outer contour of the joint extension 70. When assembled, the joint extension 70 is held in the joint receiving portion 72. The joint extension 70 and the joint receiving portion form a swivel joint. Finally, a pivot axis S is defined which runs parallel to the axis W but is offset laterally therefrom.

[0092] The inner surface of the joint receiving portion 72 forms the first fixing surface 73 of the main body 715. This surface is in form-locking contact with the outer surface of the joint extension portion 70 in the assembled state. A second fixing surface 74 is formed in the region of the recess inner wall 729 opposite the axis W. The fixing surfaces 73, 74 extend parallel to the axis W. In a vertical plane N defined perpendicular to the axis W, the fixing surfaces 73, 74 extend curvedly. The fixing surfaces 73, 74 have different radii of curvature. The fixing surfaces 73, 74 have the same axis, which corresponds to the position of the pivot axis S in the vertical plane N defined perpendicular to the axis W. Thus, the fixing surfaces 73, 74 are at least partially curved within a circular arc around the pivot axis S. This ensures smooth and guided rotation around the pivot axis S.

[0093] The second fastening surface 74 is in form-constrained contact with a correspondingly curved opposing fastening surface 75 of the weight compensation element 716 .

[0094] In the region of the second fastening surface 74, the body 715 has a number of slots 35 for passing through the clamping screws 34. In the assembled state, the clamping screws 34 are screwed into a number of holes 69 in the weight compensation element 716 and fasten the body 715 to the weight compensation element 716 by tightening.

[0095] To change the relative position of the body 715 and the weight compensation element 716, the clamping screw 34 is loosened, allowing rotation about the pivot axis S. By rotating the body 715 about the pivot axis S relative to the weight compensation element 716, the position of the combing tip 33 is changed. In particular, the combing radius R can be changed in this way to adjust the combing distance d. After the desired position is reached, the clamping screw 34 can be tightened to clamp the body 715 against the weight compensation element 716.

[0096] In the pivotable configuration of the circular comb 706, the end cover 725 is configured to match the configuration of the body 715, particularly in the area of ​​the joint receiving portion 72.

[0097] The facing surfaces of the body 715 and the weight compensation element 716 in the vertical plane N are configured differently, in particular forming differently curved fastening surfaces 73, 74 or counter-fastening surfaces 75 and the outer contour of the joint extension 70. This ensures that the body 715 can be installed on the weight compensation element 716 in a particularly predetermined orientation. The differently curved fastening surfaces 73, 74 act as orientation means and ensure the desired orientation of the body 715 and the weight compensation element 716.

[0098] A further embodiment of the circular comb 806 will be described with reference to FIG. 22. The circular comb 806 substantially corresponds to the circular comb 706 described with reference to FIGS. 19 to 21, in particular in the configuration of the main body 715. The circular comb 806 differs only in the configuration of the support mechanism 830. The support mechanism 830 has adjustment means 836 for adjusting the variable relative position of the main body 715 and the weight compensation element 816. For this purpose, an adjustment screw 865 is screwed into the weight compensation element 816. A screw head 868 of the adjustment screw 865 rests on a support edge 867 of the end cover 725. The screw head 868 is accessible at the end face to screw in or loosen the adjustment screw 865. By screwing the adjustment screw 865 into or loosening from the weight compensation element 816, the main body 715 is raised or lowered in the region of the screw head 868 and rotates about the pivot axis S. To achieve a reliable bearing effect, the support edge 867 is curved in accordance with the pivoting movement. [Explanation of symbols]
