Definitions

  • the invention relates to a card with a drum and, a working width of the drum spanning working element, which is mounted stationary on both sides outside the working width, wherein the drum is provided with a clothing which faces the working element and thereby a between the clothing of the Drum and the working element located space forms; and a working element and a setting method.
  • the width or the part of the axial length of the drum, which is covered with a set forms the working width of the card. Above this working width, a space is formed between the clothing of the drum and the respective working element. At the narrowest point of this space, a narrow gap is created.
  • the working elements span the entire working width of the drum and are attached at both ends to the drum shields arranged on both sides of the drum.
  • the existing between the set of the drum and the respective working element space or gap is not constant due to various influences during the operation of the card over the working width of the lid. Due to the changing operating conditions in the region of the gap resp. space, such as the temperature conditions, the mechanical stress on the clothing or the working element or the forces acting on the working elements or the drum forces such as centrifugal or gravitational force. Due to the influence of increasing during operation Temperature in the area of the space is an expansion of the drum and the working element.
  • the DE 20 2007 002 975 discloses a system in which between the support points of the working element actuating means are provided which allow adjustment of the space or gap between the drum and the working element over the course of the working width.
  • the working element is adjusted by means of the adjusting means at a distance to an overlying rigid element.
  • a disadvantage of this solution is that an additional element above the working element on the, the drum opposite side of the working element must be provided. This additional element must also be designed such that deforms when adjusting the actuating means, the working element and not the additional element.
  • the DE 10 2006 014 419 A1 discloses a system which attempts to counteract the operational deformation of the working elements by supplying energy, in particular heat. By thus changing the contour of the working element a constant gap during changing operating conditions should be achieved.
  • the system has the disadvantage that a contour change due to heat is sluggish.
  • the prediction of the expected change in shape when exposed to heat energy is difficult and highly dependent on the specific properties of each individual working element.
  • it results from a supply of heat energy the disadvantage that the heat balance of the carding and the working element itself is changed, which in turn can lead to an undesirable influence of other components.
  • the invention has for its object to provide a card of the type described above, which avoids the disadvantages mentioned and allows adapted to the operating conditions over the entire working width of the card room between drum set and work items.
  • the working elements are influenced by means of a new device to the effect that by generating at least one actuating force, a deformation of the working element can be achieved. It is possible that on the revolving lid an adjusting force introduced by an adjusting device acts, which allows adjusting the gap or space between the drum set and the working element in the course of the working width due to the production and adjustment of individual components or changing operating conditions.
  • the manufacturing and adjustment data of a component or the changing operating conditions can be specified on the basis of operating parameters.
  • Such operating parameters are, for example, the ambient conditions (temperature, pressure, atmospheric humidity), the properties and conditions of a component (temperature, production, wear), the properties of the material to be processed or the achievable or the current operating values (production volume, carding quality).
  • the adjusting device is integrated in the working element.
  • the working elements such as carding, knife or cover and guide elements of today's Wanderdeckelkarden are usually stored on the drum shields on both sides of the drum stationary.
  • the drum blades are located outside the working width corresponding to the width or axial length of the garnished portion of the drum.
  • the working elements span between these drum shields the drum over its entire working width.
  • Carding machines used today have a working width of more than 1000 mm, usually more than 1200 mm, preferably 1500 mm.
  • a working element In a first embodiment of a working element according to the invention, at least one magnet in the design of a permanent magnet is provided in the working element.
  • a magnetic field is built up, which is dependent on the strength of the magnet itself and its location. If the position of the magnet is changed, the position of the magnetic field and thus the influence on the magnetic body arranged within the magnetic field also change.
  • the structure of the magnetic field is oriented so that the drum gets into the area of influence of the field, whereby an attraction force is generated between the working element and the drum. This attraction is used as a force for the working element, which leads to a deformation of the working element.
  • the change in the position of the magnet can be done mechanically, for example by rotation of the magnet.
  • the magnitude of the change in position is determined by a control outside the working element due to the prevailing operating parameters.
  • At least one electromagnet or a combination of permanent magnet and electromagnet is installed in the working element.
  • the electromagnet By the electromagnet, a magnetic field is constructed or amplified by the permanent magnet field constructed or changed, which is dependent on the power of the electromagnet in its strength.
  • the working element is attracted to the drum more or less strongly.
  • the working element is deformed accordingly, which is reflected in a change in the geometry of the space between the drum set and the working element.
  • the installation location in the working element depends on the design of the working element.
  • a control of the electrical supply of the electromagnet allows to control or regulate the deformation of the working element. Such a control can be carried out depending on various operating parameters.
  • FIG. 1 shows a side view of a known Wanderdeckelkarde 1 in a schematic representation.
  • the fiber flakes 2 to be carded which may consist of natural fibers or synthetic fibers or mixtures thereof, are fed into the hopper (not shown) in the form of dissolved and cleaned flakes, taken over by a buffurizer or a licker-in 3 as a wadding template and a drum or tambour Pass a drum 4.
  • the flakes are dissolved on the drum 4, cleaned and parallelized.
  • This process takes place by the interaction of drum 4 and various stationary working elements 7, 8, 9, 10 and a traveling lid unit 5, which traveling lid 6 leads along part of the circumference of the drum 4.
  • Stationary work elements are, for example, carding elements 7, knives 8 and guide or cover elements 9, 10.
  • different sized or even more distributed on the circumference of the drum 4 working elements 7, 8, 9, 10 are used.
  • the fibers form the non-woven fabric located on the drum 4, which is then removed from a doffer roller 11 and formed in a conventional manner in a, consisting of different rolls, discharge section 12 to a card sliver 13.
  • This card sliver 13 is then deposited by a sliver tray (not shown) in a transport can in a cycloidal manner.
  • FIG. 2 shows a cross section of a known card in a schematic representation at the point II of FIG. 1 FIG. 2 These serve on the one hand for supporting the drum 4 and on the other hand for fixing the working elements 7, 8.
  • the working elements 7, 8 are fixed only on both sides of the drum 4 on the drum shields 14 and span the entire working width B of the drum 4.
  • the working width corresponds to the axial length of the garnished surface 16 of the drum 4th
  • FIGS. 3, 4 and 5 show a schematic representation of a stationary Kardierelement 7 with an inventive embodiment of a means 23 for generating a force F.
  • FIG. 3 a representation of the cross section at the point J of FIG. 4 and the FIG. 5 an enlarged excerpt from the FIG. 4 shows.
  • the carding element 7 shown is composed of the support body 20 and the clothing 15.
  • the support body 20 is held on the drum shields 14 fixed by means of fasteners 25. Between the drum shields and the drum 4 is mounted. Between the clothing 15 of the carding element 7 and the drum set 16, the space 22 and the gap 21 is shown, which extend over the working width B.
  • the electrical supply 24 is in FIG. 5 shown as an example, wherein as a starting point, a controller 30 is shown, with which the directed by the magnetic field against the drum force F can be controlled in dependence of various operating parameters.
  • FIG. 6 shows a schematic representation of a knife 44 with an inventive embodiment of a means for generating a force.
  • the knife 44 is held by a support body.
  • the supporting body is formed by a first carrier half 41 and a second Trag Eisenierfte 42, which are held together by the support body connection 43.
  • the two support body halves 42, 43 form a suction space 40 through which the contaminant deposited by the knife 44 can be sucked off.
  • the illustrated exemplary construction of a working element 8 with a knife 44 additionally includes a carding element with a clothing 15.
  • the gap 21 between the working element 8 and the clothing 16 of the drum is determined by deformation of the working element 8 due to the restoring forces F1, F2.
  • magnets 46, 47 are installed in the support body 41. These may be permanent magnets or electromagnets or a combination thereof. In further cavities 46 of the support structure, a necessary Cable guide for the electrical supply or mechanical drives for changing the position of the magnets 46, 47 are housed.
