Definitions

  • the invention relates to a device on a spinning preparation machine, in particular a carding or carding machine, with a garnished drum, said device comprising an elongate support body which can be arranged at a distance from the garnished drum. Furthermore, the invention relates to a method for producing a working element for a spinning preparation machine.
  • rod-shaped elements eg to flat rods
  • a spinning preparation machine eg carding machine or carding machine
  • Such rod-shaped elements generally extend over the working width of the card, and for this purpose comprise an elongated carrier profile, which is usually designed as a hollow profile.
  • Examples of such hollow profiles, which are used for flat bars are made WO 2006/039829 A1 .
  • the invention has for its object to provide for a spinning preparation machine, a device and an associated manufacturing method, which requires less space and at the same time has improved mechanical properties.
  • the invention includes the technical teaching that in the device at least a part of the support body, or the support body as a whole, along its longitudinal extent has a variable cross-section, such that the support body (or at least a part thereof) in cross-section orthogonal to the longitudinal extent adjacent at the lateral end faces in each case a first height and in its symmetrical center has a second height, wherein the first height is smaller than the second height.
  • the invention provides a method for producing a working element for a spinning preparation machine, wherein a back part of an elongated support body of the working element can be formed as a closed hollow body by means of the hydroforming process of the material aluminum. Alternatively, steel, plastic or a composite material can be used.
  • the back part of the support body has in cross-section orthogonal to the longitudinal axis of the support body adjacent to the lateral end faces respectively a first height and in the symmetrical center of the support body on a second height, wherein the first height is smaller than the second height.
  • Said change in cross section of the support body of the device according to the invention is thus formed in a part or region thereof, which is located on a side facing away from the foot part or opposite side of the support body. This part or region of the support body is also referred to as the back part.
  • the invention is based on the essential finding that the supporting body of the device has a variable cross-section over its longitudinal extent, wherein the height of the supporting body decreases in the direction of its lateral end faces.
  • the support body adjacent to its end faces - in cross-section and orthogonal to its longitudinal axis - a first height, which is smaller compared to the second height, which has the support body in the symmetrical center.
  • the support body is on the side facing away from the drum of a card or opposite thereto, at its end faces or adjacent thereto less high than compared to its symmetrical center. Thanks to this reduced height of the support body at its end faces, the device advantageously takes up less space or height, which can then be used within a spinning preparation machine, for example in the form of a card or carding, for other purposes.
  • the above-described decrease in the height of the support body in the direction of its lateral end faces leads to the further advantage that there the device has less mass, which otherwise led to a possible deflection of the elongate support body by its own weight.
  • the device according to the invention thus obtains an optimum cross-section along its longitudinal extent, e.g. over the working width of a card, in terms of mass, resistance moment and temperature-induced deformation.
  • the device according to the invention can in principle be used as a carrier element in a spinning preparation machine.
  • the device may e.g. in a card or card, serve as a stationary or moving working element, e.g. as Kardierelement, Verschalungselement, knife or as a solid or flat rod on which a set is attached.
  • the first height of the support element equal to 0.8 times the value of the second height, or less corresponds.
  • the first height of the support element adjacent to its end faces is selected such that it is less than 0.8 times the value of the second height in the symmetrical center of the support element.
  • the first height of the support member may be less than 0.7 times, or less than 0.6 times, or less than 0.5 times, or less than 0.4 times, or less than 0.3 times the value, or even less than 0.2 times the second height of the support element, or equal to these 0.7-0.2 times the second height values.
  • the degree of reduction of the first height of the support member relative to the second height may be suitable for example in Depending on a total length of the device and its support body, the material used for this purpose or the type of spinning preparation machine be selected.
  • the support body is formed the same along its longitudinal extent on both sides of its symmetrical center.
  • the support body is formed symmetrically on both sides of its center and in the direction of the lateral end faces.
  • An asymmetrical design along its longitudinal extent may be useful if the carding or carding needs to absorb a one-sided heat load, for example by a motor arranged on one side, which emits its heat to a side plate.
  • an upper free edge of the support body which is the garnished drum facing away from a card or opposite, between the symmetrical center of the support body (with the second height) and the two end faces (with the first height) each have a linear Have history.
  • the upper free edge of the support body between the symmetrical center and the end faces in each case has a curved course, for example in the form of an arc, a parabola or a curve. In any case, it is ensured by such a course of the upper free edge of the support body that the support body has at its two end faces or adjacent thereto in cross section the first height, which is smaller compared to the second height in the symmetrical center of the support body.
  • the support body thereof may comprise a foot part provided on the support body on the side, which in case of installation of the device e.g. in a card in comparison to the garnished drum of the card arrives.
  • the width of such a foot part, transverse to the longitudinal extent of the support body, is substantially constant, which makes the attachment e.g. simplified a set.
  • the support body of the device according to the invention also comprises a back part, which adjoins the foot part and facing away from the garnished drum or arranged opposite thereto. The above-described change in cross section along the longitudinal extent of the support body is then formed in the back part.
  • the device and its support body For the production of the device and its support body is particularly suitable a material with a good heat transfer coefficient, thanks to which then a good release of heat is ensured during operation of the spinning preparation machine via convection.
  • a light metal e.g., aluminum
  • the device and its support body can also be made from fiber reinforced plastic (e.g., CFRP material).
  • the support body may be formed with its back part as a closed hollow body, wherein the lateral end faces of this hollow body remain open.
  • the hydroforming method can be used, preferably a light metal, for example Aluminum, for the formation of the back part of the support body, or the complete support body, is used.
  • the device according to the present invention is characterized by an optimal design in cross section along the longitudinal extent of the support body, wherein at the lateral end faces of the support body a lower height (first height) is present compared to the symmetrical center of the support body (second height).

  • Fig. 3c shows the device 100 in the assembled state, when the clothing strip 132 is attached to the foot part 128 of the support body 120.
  • an additional layer 135 (cf. Fig. 3a ) is provided, which contains at least ferrous material or consists of such iron material.
  • This additional layer 135 may be attached to the foot part 128, for example by gluing.
  • a plurality of segments 137 may be fastened to a rear side 136 of the support element 133. This is from the Fig. 4 or. Fig. 5 can be seen, which show a top view and a simplified side view of the back 136 of the support member 133.
  • the segments 137 are fastened or glued to the rear side 136 of the support element 133, preferably by using adhesive G, as individualized bodies. If the segments 137 are each made of steel, the segments 137 form a backing layer 132R (see FIG. Fig. 5 ) of the clothing strip 132, which contains iron material.

  • Fig. 6 illustrates that the support body 120 along its longitudinal extent L has a variable cross section, such that adjacent to its end faces 122, a first height h 1 is present, which is smaller than the second height h 2 in the symmetrical center 124 of the support body 120th Diescum achieved in that an upper free edge 126 of the support body 120, which the foot part 128 and thus the drum 4 of the card K is opposite, starting from the symmetrical center 124 of the support body 120 in the direction of the end faces 122 has a sloping curved course, for example in the form of a parabola. This then leads to the fact that the first height h 1 at the end faces is smaller in each case than the second height h 2 in the symmetrical center 124.
  • the upper free edge 126 of the support body 126 may also assume a linearly sloping course, as in Fig. 6 indicated by dashed lines.
  • the support body 120 may have at the end faces 122 a height h1, which is slightly larger than the height h2. This assumes that the cross sections of the wall thicknesses and thus moments of resistance to the center 124 of the support body 120 remain the same or even increase. The support body 120 would thus have a slightly widening from the center 124 to the end faces 122 cavity, which may be useful manufacturing technology. At a smaller height h2, the wall thickness in the center 124 of the support body 120 would then be greater than at the edge in the region of the end faces 122. The wall thickness would thus decrease from the center 124 to the end faces 122.
  • the rear part 130 formed as a hollow profile is open on the end face 122 of the support body 120.
  • the cavities within the back portion 130 are not hermetically sealed, so that an exchange of air to the side is possible.

  • Additional webs 139 are provided inside the back part 130, with which the stability and dissipation of the heat from the clothing strip into the back part for the support body 120 along its longitudinal extension L is further improved.
  • the support body 120 adjacent to its end faces 122 has a first height h 1 (analogous to Fig. 7.1 and Fig. 8.1 ), which is smaller compared to the second height h 2 .
