Definitions

  • the present invention relates to a round comb for a combing machine, and a combing head with such a round comb.
  • Such round combs are used for combing machines for combing a submitted fiber mass (cotton, wool, etc.), wherein the presentation of the fiber mass can be in the form of cotton webs wound on sleeves or in the form of individual fiber ribbons.
  • the number of combs (combs / minute) have increased significantly in recent years, which also increases productivity.
  • the round combs used for the combing machine in practice consist of a round comb carrier which is provided with a clamping hub with which it is fastened in a rotationally fixed manner on a driven round comb shaft.
  • a clothing carrier is attached to a partial circumference of the circular comb carrier, which takes up the combing clothing which combs out the end of the fiber mass (also called tuft) presented by a nipper unit.
  • round comb supports are used which are held directly on a driven round comb shaft.
  • the EP 2 789 716 A1 a circular comb with a carrier which is provided with an inner section protruding towards the shaft, which has a recess which is open in the direction of the shaft and extends in the longitudinal direction of the hollow profile and in which a support element is accommodated, which on the one hand extends over a first Support surface is supported on a base surface of the recess and on the other hand via a second support surface on the outer circumference of the shaft.
  • Interchangeable spacer elements are provided between the support element and the base of the recess. This is intended to make it possible to set the radius of the enveloping circle of the combing clothing exactly by simply inserting precise spacer elements between the base body and the support element.
  • the wedge elements are disclosed in various embodiments.
  • the wedge elements are inserted between the circular comb carrier and a comb segment carrier.
  • the disadvantage is that special comb segment carriers must be made available, which cannot be used on comb carriers without height adjustment.
  • the wedge elements are between the comb carriers and introduced the round comb shaft.
  • the disadvantage is that the shape of the wedge elements must be adapted to the round comb shaft or vice versa in order to obtain a sufficient support.
  • the wedge elements are to be provided guided in the axial direction of the circular comb shaft in order to avoid tilting and thus blocking of the wedge elements or damage to the surface of the circular comb shaft when the wedge elements are shifted for the purpose of height adjustment.
  • the object of the present invention is therefore to create a circular comb which enables continuous adjustment of the distance between the lower tong plate of the tongs and the enveloping circle of the combing clothing of the circular comb, with easy retrofitting to existing combing machines without reworking or replacement of components of the machines existing clothing carrier is made possible.
  • a circular comb for a combing machine having a combing clothing and a circular comb axis, with a clothing carrier and at least one circular comb carrier.
  • the clothing carrier is held on the circular comb carrier and the circular comb carrier is attached to a circular comb shaft with connecting screws.
  • a cover plate is attached to each end of the circular comb carrier viewed in the direction of the circular comb axis.
  • An insert rail is provided between the circular comb support and the circular comb shaft.
  • At least two adjusting devices are provided between the circular comb carrier and the insert rail for adjusting a distance between the circular comb shaft and the circular comb carrier.
  • the distance between the lower pliers plate of the pliers and the enveloping circle of the combing assembly also changes when the distance between the round comb carrier and the round comb shaft is adjusted.
  • the insert rail comes to rest against the surface of the circular comb shaft and the circular comb carrier is connected through the insert rail to the circular comb shaft via appropriate connecting elements, for example screws or bolts.
  • the adjustment device is arranged between the insert rail and the circular comb carrier, this has the advantage that the distance is adjusted within the circular comb and on the one hand the shape or nature of the surface of the circular comb shaft has no influence on the adjusting device and on the other hand the circular comb shaft is not damaged by the adjusting device can be. Furthermore, the contact surface of the insert rail which comes to rest on the surface of the circular comb shaft can be matched to the circular comb shaft.
  • the stick-slip effect can be reduced or eliminated, which leads to greater adjustment precision. It also provides protection against excessive tightening and possible permanent deformations, which could reduce the service life and setting precision. It is advantageous if the entire length of the insert rail is not used for the installation, but rather a certain area around the fastening point of the circular comb support is designed as a separate support. With this construction, the proposed device can be adapted in a simple manner to the conditions in existing systems and a simple exchange of the round combs is possible.
  • the clothing carrier has a clothing support surface on its side facing away from the circular comb shaft.
  • a comb clothing is attached to the clothing support surface using suitable means, for example with screws, clamps, welding or gluing.
  • Combing clothing consisting of individual wire strips applied to the clothing support surface or combing clothing consisting of prefabricated combing elements which are applied to the clothing support surface are used.
  • the clothing support surface is arranged in the shape of a segment of a circle around the circular comb axis.
  • the circular comb carrier and the clothing carrier are advantageously designed in one piece.
  • the clothing support surface is formed by the outer surface of the circular comb support.
  • the at least two adjustment devices between the circular comb carrier and the insert rail are advantageously provided in a respective end region of the circular comb carrier. Because the adjustment devices are arranged at the outer ends of the circular comb, the adjustment devices can be easily adjusted from the side of the circular comb. A more stable support of the circular comb carrier on the adjustment devices is also possible if these are provided at a greater distance from one another.
  • the insert rail is advantageously connected in a force-locking manner through a through opening in the circular comb shaft with the circular comb shaft via a fastening screw.
  • This construction ensures a simple connection between the round comb shaft and the insert rail.
  • the insert rail is immovably connected to the round comb shaft. This connection does not have to be released when the adjustment device is readjusted, which contributes to an improvement in the adjustment accuracy.
  • the insert rail is preferably connected to the circular comb carrier via a shoulder screw, the shoulder of the shoulder screw engaging in a recess in the fitting carrier and a screw head of the shoulder screw engaging in a recess in the insert rail on a side of the insert rail opposite the fitting carrier and between the insert rail and the screw head a spring element is arranged on the shoulder screw.
  • the actuation of the adjusting device is not hindered by the spring element.
  • the advantage of the spring element is that when the distance between the insert rail and the clothing carrier changes, there is always a cohesive force between the clothing carrier and the insert rail. This has a particularly positive effect when the distance is reduced. In this case, the clothing carrier is drawn towards the insert rail by the spring element and the distance can be adjusted without play at any time.
  • a wave spring which has a minimum restoring force of 70 N is particularly preferably used as the spring element.
  • the circular comb carrier is advantageously connected to the insert rail in a form-fitting manner by a force transmission element, the force transmission element being designed as a bolt with an internal thread that engages in a recess in the circular comb carrier and a through opening of the insert rail, and the bolt through a through opening in the circular comb shaft is positively connected to the round comb shaft via a screw.
  • An end face of the bolt facing the circular comb shaft is spaced from a surface of the circular comb shaft by a shoulder which is pronounced on an outer surface of the bolt and which is supported on the insert rail and by a corresponding length of the bolt section protruding into the insert rail.
  • an O-ring or, advantageously, two O-rings enables the bolts to be inserted without play into the circular comb support and the insert rail.
  • the O-rings act as damping elements, which in the case of the acceleration forces that occur, wear and tear due to a reversal of direction which counteracts occurring forces and contributes to less wear on the components.
  • the fit between the bolt and the circular comb carrier is advantageously chosen so that the O-ring and the surfaces support each other for maximum service life and power transmission. Since the power transmission no longer has to be absorbed by the frictional connection between the circular comb support and the circular comb shaft, the support can be manufactured more easily.
  • a transition or press fit can be provided between the bolt and the circular comb support or the insert rail. It is premature to use a different material pairing, such as aluminum and bronze, to prevent contact corrosion or fusing.
  • the adjustment device comprises flat wedges arranged between the insert rail and the circular comb carrier, which, starting from the respective end of the clothing carrier, have a continuous cross-sectional tapering towards the insert rail or the circular comb carrier in the direction of the circular comb axis.
  • This tapering of the cross-section changes the spacing between the insert rail and the circular comb when the flat wedges are shifted in the direction of the circular comb axis.
  • the design of the flat wedges is adapted to the shape of the circular comb support and the insert rail. Since the flat wedges have no contact with the round comb shaft or the clothing carrier, the flat wedges can be precisely adapted to the conditions in the round comb, regardless of these components that usually exist.
  • the respective connecting screws of the circular comb support preferably engage in the circular comb shaft through an opening provided in the respective flat wedge and a through opening provided in the insert rail.
  • the connecting screws of the circular comb carrier can also be used to secure the adjustment device.
  • the connecting screws can be screwed into an internal thread in the round comb shaft or an internal thread in the round comb support or in a threaded nut to brace the round comb support with the round comb shaft. Also prevents the Implementation of the connecting element through the opening of the flat wedge a lateral slipping out of the flat wedge during an adjustment.
  • the adjustment device After loosening the connecting screws for attaching the circular comb carrier to the circular comb shaft, the adjustment device enables the distance between the lower tong plate and the enveloping circle of the comb clothing on the clothing carrier to be easily adjusted without the circular comb having to be removed from the combing head when the setting is changed .
  • a setting can thus also be checked directly in the installed state by measuring the distance between the lower tong plate and the enveloping circle of the comb clothing located on the clothing carrier.
  • the circular comb can be rotated into a measuring position when installed, in which the distance can be set and measured.
  • the device enables the height to be set in the measuring position without having to pivot the comb for adjustment and fixation or even having to be removed from the machine for height adjustment.
  • a contact surface of the flat wedges facing the circular comb carrier is molded onto a contact surface provided on the insert rail.
  • the continuous cross-sectional tapering is preferably provided by a bevel of a support surface of the flat wedge facing the circular comb carrier, the bevel having a wedge angle ⁇ of 11 degrees or less. Choosing a wedge angle of less than 11 degrees ensures that the flat wedge is self-locking. The flat wedge thus remains in its position when the connecting screws of the circular comb carrier with the circular comb shaft are tightened. Furthermore, the angle of the flat wedge is selected so that the static friction conditions of the system are not overcome by the screw force; the flat wedge preferably has a wedge angle of 10 degrees.
  • the support surface of the flat wedge facing the circular comb support is advantageously designed with a convex curvature.
  • the slight curvature of the support surface results in a defined support (theoretical line) of the circular comb support on the flat wedge.
  • an inclined position from left to right of the comb can be precisely adjusted through the curvature in order to adapt precisely to a possible inclined position of the tongs for the best combing performance. If different heights are set on the left and right, this results in a line overlay which, depending on the size of the angle, moves further away from an axis of the connecting screw. This leads to deformations and height errors when tightening the connecting screw.
  • the curvature results in a defined central support surface independent of the left-right offset.
  • the insert rail which is molded onto the round comb shaft and is designed as a flat surface on the side facing away from the round comb shaft, results in a great advantage in production and thus in manufacturing costs of the insert rail and the wedge by dividing the curved surfaces into two Components.
  • the respective flat wedge is preferably provided with an adjusting screw held in the respective cover plate, the adjusting screw being arranged with its axis parallel to the circular comb axis. Because the adjusting screw is held in the cover plate, the circular comb carrier can be removed without losing the flat wedges.
  • the flat wedges are removed from the combing head together with the cover plates that are connected to the circular comb carrier. Furthermore, due to the axially parallel arrangement of the adjusting screw, it is possible to adjust the flat wedges at the end from outside the circular comb. It is not necessary to remove the circular comb or parts of it for adjustment.
  • the adjusting screw is preferably held rotatably in its axial position in the cover plate and an internal thread is provided in the flat wedge, the position of the flat wedge relative to the circular comb carrier in the direction of the circular comb axis being adjustable by engaging the adjusting screw in the internal thread in the flat wedge by turning the adjusting screw. Since the adjusting screw does not change its axial position due to the axial fixation even when turning, the thread of the adjusting screw, which is in engagement with the internal thread of the flat wedge, moves the flat wedge axially according to the pitch of the internal thread in relation to the circular comb axis.
  • a through opening in the form of an elongated hole or a correspondingly large bore is advantageously provided in the cover plate.
  • a locking ring also known as a Seeger ring, can be used to axially fix the adjusting screw.
  • a corresponding shape of the passage opening in the cover plate and the adjusting screw can also be provided in order to achieve an axial retention of the adjusting screw. The insertion of a locking ring is an easy to assemble and inexpensive construction to hold the adjusting screw in its axial position.
  • the opening in the flat wedge is advantageously designed as a bore, an elongated hole or a slot which is open towards a side facing away from the end of the clothing carrier.
  • a design in the form of an open slot enables a simple exchange of a flat wedge without completely detaching the circular comb carrier from the insert rail.
  • the design in the form of an open slot also prevents the flat wedge from slipping out sideways when adjusting after loosening the connecting screws.
  • Configuring the opening as a bore or elongated hole has the advantage that the flat wedge has a larger, compact support surface.
  • the distance between the insert rail and the circular comb support is advantageously 0 mm to 1.5 mm. It has been shown that the distance in this area can be adjusted by using flat wedges and is also sufficient for the necessary adjustment of the distance between the lower tong plate of the tongs and the outer circle of the combing clothing for the fiber material to be processed in a combing room.
  • At least two adjustment devices are preferably provided in a respective end region of the circular comb carrier.
  • the direction of rotation of the circular comb results in an inlet side with which the combing clothing first meets a tuft to be combed. Due to its rotation, the circular comb moves through the tuft until it leaves it again on the outlet side of the combing clothing.

  • the insert rail 31, which is braced on the circular comb shaft 8 with fastening screws 45, can also remain on the circular comb shaft 8. Furthermore, the circular comb carrier 9 and the insert rail 31 are connected to one another via shoulder screws 46 and are pressed against one another by a spring element 47. The shoulder screws 46 provide a simple and exact positioning of the circular comb carrier 8 regardless of its attachment.
  • FIG Figure 8 shows an enlarged schematic representation of the detail Z according to FIG Figure 7 .
  • the illustration shows the connection between the circular comb support 9 and the insert rail 31 with a shoulder screw 46 and a spring element 47, shown here as a wave spring 47.
  • the shoulder screw 46 is inserted into a recess 50 of the insert rail 31 and screwed into the circular comb support 9.
  • the shoulder 48 of the shoulder screw 46 fits into a recess of the circular comb support 9 and forms a fit D with this recess.
  • the fit D has the advantage that the circular comb support 9 is automatically positioned relative to the insert rail 31 and thus a one-time setting of the Insert rail 31 must take place opposite the round comb shaft.
  • the wave spring 47 is inserted between the screw head 49 of the shoulder screw 46 and the insert rail 31 and, with its spring force, presses the insert rail 31 against the circular comb carrier 9.
