Definitions

  • the invention relates to a card with a revolving flat, comprising at least two traction means, which are designed to receive a plurality of flat bars in the area of their end faces and to guide them at least along a partial circumference of a drum of the card, the traction means with the flat bars around two pulleys each are performed, which are arranged above the side plates of the card, according to the preamble of claim 1.
  • DE 2604465 A1 discloses a revolving flat of a card, in which the flat rods are arranged on revolving belts or chains and are guided past a partial circumference of the drum in a circuit.
  • two guide rollers are arranged at the deflection points of the belt drive.
  • Guide elements or sliding guides are arranged between the guide rollers and are attached to flanges or members.
  • the flanges or structural members in turn extend from the side plate to the upper sliding guide, as a result of which the installation space between the rotating flat bars is only freely accessible to a limited extent.
  • the belt or chain can be adjusted using a spring balance by measuring the contact force of a flat bar on the flexible bend or the sliding guide. This is very imprecise and only gives an indirect indication of the tension in the belt or chain.
  • the object of the invention is to develop a revolving flat for a card, which allows easy access to the flat bars and which enables reproducible adjustment. This object is achieved with the features of claim 1. Advantageous further developments of the invention are given in the dependent claims.
  • the card according to the invention has a revolving flat which comprises at least two traction means which are designed to receive a plurality of flat bars in the area of their end faces and to guide them at least along a partial circumference of a drum of the card, the traction means with the flat bars being guided around two deflection rollers each which are arranged above the side plates of the card,
  • the invention is characterized in that a bracket is arranged between each two deflection rollers, which bracket is designed to accommodate further guide elements for guiding the traction means, the ends of the bracket being arranged on flanges on which the deflection rollers are mounted.
  • the traction means can be designed as a belt or chain and take the flat bars in the area of their end faces with pins,
  • the traction means guide the flat rods along their flat travel at least along a partial circumference of a drum, so that fibers between the sets of the covers and the sets of the drum are aligned and cleaned in a very small gap.
  • the traction means are guided around two pulleys each, with the flat bars in the area of one pulley being moved out of contact with the fibers or the drum and cleaned by means of suction and brushing before they are returned to the drum in the region of the second pulley .
  • At least one roller is designed to drive the traction means with a drive.
  • a bracket is arranged between each two deflection rollers, which is formed, further To accommodate guide elements for guiding the traction means, a free space is created between the lower and upper run of the traction means that can be used to inspect or remove the flat bars or to clean them.
  • the free space in the area of the side plates is not built with fastening elements on which the bracket is arranged.
  • the bracket preferably has a first and a second end which are arranged in the region of the deflection rollers, the bracket bridging at least a partial distance between the deflection rollers in an arc shape.
  • the design of the bracket as an arched bridge enables a high level of stability and generous design freedom for the free space between the upper and lower run of the traction means.
  • a first end of the bracket is designed to be rotatable and the second end has a support which rests on an adjusting element. The result is easy assembly of the bracket, which no longer has to be laboriously mounted and adjusted on the side plate of the card.
  • the bracket Because the second end of the bracket is pressed onto the adjusting element by the tension of the traction means, there is no need for the bracket to be actively fastened to this second end.
  • the tension of the traction mechanism ensures a permanent and precise contact with the adjustment element.
  • the setting element is preferably designed as an eccentric which interacts with the support of the bracket.
  • the clamping force on the traction device can be adjusted via the eccentric, because depending on the position of the eccentric, the bracket presses more or less against the tension of the traction device. Because the bracket is designed to be pivoted with its first end with a defined force about a pivot point, the tension on the traction means can be adjusted easily and precisely
  • a defined force is preferably introduced at the second end of the bracket, with the pivoted position of the bracket being fixed by bracing the eccentric which is in contact with the support of the bracket.
  • the defined force can be generated, for example, with springs, pneumatic or hydraulic means or by means of lever force.
  • the bracket preferably has at least two further deflection rollers for guiding the traction means, as a result of which there is little friction on the deflection of the traction means.
  • the use of two further deflection rollers that is to say a total of four deflection rollers per bracket, enables the use of deflection rollers with a small diameter, whereby the free space between the upper and lower run of the traction means can be increased.
  • the additional guide element on the bracket reduces the tension on the traction mechanism due to the weight of the flat bars.
  • a large free space can be created between the traction means, with which the flat bars can easily be mounted or can be removed.
  • the free space is also suitable for inspecting the condition of the flat bars and can be used to clean the revolving flat.
  • the traction means can be tensioned reproducibly with the simplest means.

  • the fibers of the fiber flocks are parallelized and cleaned by means of stationary rotating carding elements 20 arranged on a revolving cover 17.
  • the resulting fiber web is then conveyed via a pick-up 5, a pick-up roller 6 and several nip rollers 7, 8, to a fleece guide element 9, which transforms the fiber web with a funnel 10 into a fiber band, which is sent via take-off rollers 11, 12 to a downstream processing machine or a Can 15 passes.
  • FIG. 2 shows a revolving cover 17 according to the prior art.
  • the revolving cover 17 comprises at least two belts 17a, which are arranged on both sides of the drum 4 and in the region of the end faces of the flat bars 20 interact with pins arranged thereon. That is, each flat bar 20 is fastened on both sides by means of the pins arranged on the end face in a respective belt 17a, which are guided above the side plates 22 and arranged around the circumference.

  • the flexible bend 21 is arranged on the side plate so as to be adjustable by means of the adjusting spindle 19.
  • the sliding strip 18 can be designed to be adjustable concentrically to the drum at a distance from the flexible bend 21.
  • the carding gap between the drum 4 and the flat bars 20 can be adjusted by adjusting the flexible arch 21 and the sliding strip 18.
  • the flat bars 20 move in the area of the drum 4 or the visible side plate 22 to the left against the direction of rotation of the drum 4, the flat bars 20 being guided here over the sliding strip 18.
  • the flat bars 20 are moved to the right in this illustration by the belt 17a.
  • the tension of the belt 17a is generated exclusively by the bracket 23, which is arranged adjustably at a central position on the side plate 22.
  • the contour of the bracket 23 corresponds to the triangular contour of an upturned clothes hanger, the adjusting device 23a with the attachment to the side plate 22 being arranged at a central corner (the suspension of the clothes hanger), and the pulleys 26 and 27 being rotatably mounted at the other two corners .
  • the arrangement and contour of the bracket 23 has the disadvantage that the belt tension can be adjusted, which is complex, and the lack of accessibility in the revolving cover 17 between the flat bars 20.
  • the revolving flat 17 according to the invention is guided on each side of the card 100 between the deflection rollers 24 and 25 on at least two further deflection rollers 26, 27 which are arranged on a curved bracket 23.
