Definitions

  • Such round combs are used for combing machines for combing a submitted fiber mass (cotton, wool, etc.), whereby the fiber mass can be presented 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 tong assembly.
  • round comb supports are used which are held directly on a driven round comb shaft.
  • 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 support 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 side of the insert rail facing away from the circular comb support comes into contact with the surface of the circular comb shaft and the circular comb support 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 support 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 easily adapted to the conditions in existing systems and the round combs can be exchanged easily.
  • 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 passes 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 apart from a surface of the circular comb shaft by a shoulder which is pronounced on an outer surface of the bolt and 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 into the circular comb support and the insert rail without play.
  • 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 the forces that occur and contributes to less wear and tear 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 one another 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.
  • 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. Due to this cross-sectional tapering, the spacing between the insert rail and the circular comb is changed 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 adapted exactly 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. After the setting has been made, it is secured again by simply tightening the connecting screws to attach the circular comb support to the circular comb shaft.
  • the device enables the height to be adjusted 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 support surface of the flat wedge facing the circular comb carrier 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 from 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 support 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 on the face side 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, whereby the position of the flat wedge relative to the circular comb carrier can be adjusted in the direction of the circular comb axis 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, shifts the flat wedge axially according to the pitch of the internal thread in relation to the circular comb axis.
  • 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 use 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 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 support from the insert rail.
  • the design in the form of an open slot also prevents the flat wedge from slipping out to the side during an adjustment after the connecting screws have been loosened.
  • Configuring the opening as a bore or elongated hole has the advantage that the flat wedge has a larger, compact contact 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 enveloping circle of the combing clothing for the fiber material to be processed in a combing facility.
  • the distance between the clothing carrier and the circular comb carrier on an inlet side of the combing clothing from the distance between the clothing carrier and the circular comb carrier on an outlet side of the combing clothing is around 0 , Differs from 1 mm to 1.5 mm.

  • the fastening of the counterweight 11 takes place, as shown schematically, by means of the screws 12, by means of which the counterweight 11 is fastened to the circular comb supports 9.
  • the tong assembly is formed from a tong frame 14 to which a lower tong plate 15 and an upper tong plate 16 are attached.
