Definitions

  • the invention relates to a combing machine with a plurality of combing points, wherein the fiber ribbons formed at the individual combing points are fed via guide elements of a drafting unit and the nonwoven fabric delivered by the drafting unit is combined via a nonwoven summary to form a sliver which is delivered to a driven transporting means , which transfers the sliver to a delivery point at which the sliver is deflected and discharged in a vertical direction down to a sliver tray.
  • Combination machines are known in practice, wherein the fiber slivers formed on the individual combing heads (combing points) are placed next to one another on a delivery table and transferred to a subsequent drafting unit.
  • This drafting unit is usually slightly above the outlet table, whereby only a short rising ramp between the drafting unit and the end of the outlet table is necessary to transfer the slivers from the outlet table to an input roller pair of the drafting unit.
  • the nonwoven fabric drawn and delivered by the drafting unit is combined to form a sliver by means of a nonwoven summary (eg a fleece funnel) and delivered to a driven subsequent conveyor belt.
  • a nonwoven summary eg a fleece funnel
  • Such a device is z. B. from the EP-640 705 A1 refer to.
  • the sliver is subsequently conveyed via the conveyor belt to a delivery position above a sliver deposit, from which it is delivered downwards in a vertical direction to a subsequent calender roller pair.
  • the pair of calender rolls transfers the sliver to a subsequent funnel wheel, via which the sliver is placed in loop form into a jug below it.
  • a pressure roller is provided, which forms a clamping point substantially with the conveyor belt, so that the sliver safely on the conveyor belt comes to rest and is taken.
  • the main clamping effect arises here between the pressure roller and the easily deflected conveyor belt, whereby the, performed by the nip sliver is flattened and slightly compressed.
  • the sliver can dodge in the region of the nip to the side, whereby no substantial hardening of the sliver, or no increase in the adhesive force of the sliver can be achieved. Ie. targeted solidification of the sliver is not possible with this arrangement shown.
  • a disadvantage of this design is also the arcuate transfer from the delivery point of the pair of output rollers of the drafting unit to the delivery point to the subsequent conveyor belt.
  • Each deflection point for the sliver influenced by the existing friction, the structure of the fiber structure, which can adversely affect the quality of the sliver.
  • baffle is additionally arranged in the embodiment shown.
  • the invention has the object to improve known designs and their disadvantages to avoid even with higher transport speeds for, from the drafting unit dispensed sliver can work.
  • a calender roller pair connected to a drive be present between the fleece summary and the transport means is provided, wherein in the region of the clamping point of the calender roller pair side guides are provided for, performed by the nip fiber sliver.
  • a further solidification of the sliver and thus increase the adhesive force can be achieved if the calender rolls of Kalanderwalzenpases are provided on its peripheral surface with a profiling. By this profiling, in particular the areas of the edge fibers are solidified.
  • the fleece summary is mounted pivotably about a pivot axis, transversely to the conveying direction of the sliver, in a vertical plane. This makes it possible to transfer the fleece summary of a working position in a shutdown position, for example, to be able to perform maintenance or cleaning work.
  • the pivoting mobility of the fleece summary can be used for monitoring purposes. Ie. by a congestion of the fiber material in the area of the nonwoven summary this is pivoted by the accumulation of jamming forces from their operating position in a shutdown position, which is detected by a sensor. The sensor then sends signals to a control unit, via which appropriate measures (eg switching off the combing machine) are triggered.
  • magnets may be mounted on the machine frame, which hold by their magnetic force, the nonwoven summary on the magnetic surface itself or on correspondingly associated stop surfaces.
  • a first calender roll of the calender roll pair is rotatably mounted in the machine frame and connected to a drive and the second calender roll is rotatably mounted on a pivot lever which is pivotally mounted about a pivot axis mounted on the machine frame and at a distance from the pivot axis with a pressure medium is charged.
  • pressure medium can be z. B. are used connected to a pressure source bellows cylinder, which is supported on the machine frame and the pivot lever.
  • the pivot lever is provided with mutually spaced webs, between which the second calender is rotatably mounted, wherein the webs project beyond the outer diameter of the second calender in the nip of the Kalanderwalzencrues and thus the lateral guidance of the nip make guided sliver.
  • the parallel distance between the opposite webs is chosen so that it is only slightly larger than the width of the calender rolls in the region of its outer periphery. Ie. the distance of the respective end face of the calender roll to the opposite surface of the respective web can be between 0.05 mm and 0.8 mm. Preferably, the distance is 0.1 mm.
  • the webs serve on the one hand for the rotatable mounting of the second calender roll and on the other hand for lateral guidance it guided through the nip sliver.
  • the first (lower) calender roll has the same width as the second (upper) calender roll. Since the first and the second calender roll - when viewed in the vertical direction - are exactly superimposed, the end faces of the first calender roll (like the second calender roll) also have a distance of 0 to the opposite inner surfaces of the webs, which also partially cover the first calender roll , 05-0.8 mm, or preferably of 0.1 mm.
  • the webs are connected to a transverse web, which is arranged in the region between the nip of the calender roller pair and the subsequent transport ,
  • the webs project beyond the outer diameter of the second calender roll in the region of the clamping point of the calender roll pair and thus simultaneously form the lateral guidance of the fiber sliver guided through the nip.
  • the distances between the end face of the second calender roll and the opposite surfaces of the webs to a minimum extent (0.05 - 0.8 mm) held so that lateral deflection of the sliver during the calendering (compression) is prevented in the nip between the calender rolls.
  • the webs extend over the region between the clamping point of the calender roller pair and a delivery point to the transport means laterally of a conveying plane of the sliver extend.
  • the delivery point of the drafting unit to the fleece summary, the nip of the Kalanderwalzencrues and the delivery point to the transport are approximately in one plane. This deflection points are avoided, which can adversely affect the quality of the sliver.
