Definitions

  • the invention relates to a cotton guiding plate, which is connected in a combing machine to an oscillating pliers, for guiding the cotton to be combed, which feeds into a feed cylinder mounted in the pliers.
  • Combing machines are known in which a cotton sheet guide plate is pivotally connected to the pliers at a first edge and is connected at a second edge by a hinge with hinge bolts to an edge of a second plate, the other edge of which is connected to a frame-fixed, in the case of a winding roller the combing element is pivotally connected.
  • the two articulated guide plates serve to keep the path length for the cotton, which is unwound by rotating the winding roller from a cotton winding resting on the same, in spite of the changing distance between the winding roller and the feed cylinder due to the movement of the tongs and a Avoid fluttering and misalignment of the cotton wool.
  • a disadvantage of these known cotton guiding plates is that, in particular at the high working speeds or comb play numbers required today, the hinge bearings deflect after a relatively short operating time, which leads to excessive play and excessive noise.
  • the object of the invention is to provide a cotton guide plate of the type specified at the outset, with which this disadvantage can be avoided and which can work properly even with high numbers of combs, for example at 300 to 350 combs per minute, over a long operating period.
  • the cotton guide plate according to the invention is characterized in that the plate is made of plastic, is connected at a first edge to the vibrating pliers and at a second edge to a frame-fixed element arranged at a winding roller of the combing machine and between the two edges has a reduced thickness in at least one line-shaped bending area which is approximately parallel to the edges and extends over the entire width of the plate.
  • the bending area pivotally connects two sections of the one-piece cotton guide plate to one another.
  • the plate can have additional bending areas or can be pivotally connected in another way to the pliers or to the element fixed to the frame, so that it acts essentially the same as the two known guide plates pivotally connected to one another by a hinge.
  • the cotton guide plate can suitably consist of a fiber-reinforced plastic (fiber composite material), preferably of a carbon fiber-reinforced plastic. Furthermore, a reinforcing fabric can be cast into the plate in the bending area.
  • a fiber-reinforced plastic fiber composite material
  • a reinforcing fabric can be cast into the plate in the bending area.
  • the combing head shown in FIGS. 1 and 2 has a rotating winding roller 1, a rotating round comb shaft 2, an oscillating rotatable pliers shaft 3 and two tear-off cylinders 4, all of which are mounted in a machine frame, not shown.
  • the front end of the lower part 6 of the pliers is articulated on front supports 7 which are pivotably mounted about the axis of the round comb shaft 2.
  • An upper part of the pliers 8 interacts with the lower part 6 of the pliers and is pivotally connected to the lower part 6 of the pliers by pivot 9.
  • An intermittently rotatable feed cylinder 10 is mounted in the lower tong part 6.
  • the continuously rotating round comb shaft 2 carries in the usual way a round comb 11 with a round comb segment 12 carrying comb teeth.
  • the cotton to be combed rests on the winding roller 1 in the form of a winding (not shown). Due to the rotation of the winding roller 1, the cotton is unwound from the winding and placed on a guide plate 13 and runs on this to the feed cylinder 10 and from there into the nip K (FIG. 1) between the lower part 6 and the upper part 8.
  • the guide plate 13 ensures that the path of the cotton between the winding roller 1 and the feed cylinder 10 always remains the same length during the described movement of the lower tong part 6 and thus the feed cylinder 10.
  • the guide plate 13 consists of plastic, preferably of a fiber-reinforced plastic, in particular a carbon-fiber-reinforced plastic.
  • the lower edge of the guide plate 13 is pivotally connected to the lower part 6 of the pliers.
  • at least one axis 14 is held on the lower part 6 of the pliers and is mounted in at least one body 15 fastened to the guide plate 13, which is snapped onto the axis 14.
  • the axis 14 can extend over the entire width of the guide plate 13 and can be mounted in one or more bodies 15 fastened to the guide plate 13.
  • a shorter axis 14 can be held on the lower part 6 of the pliers at each of the two lateral edges of the guide plate 13, onto each of which a body 15 is snapped.
  • the arrangement of the axes 14 and the bodies 15 snapped onto them could of course also be reversed, that is to say the axes 14 could be attached to the guide plate 13 and the bodies 15 attached to the lower part 6 of the pliers.
  • the upper edge of the guide plate 13 is pivotally connected to an element 16 which is arranged on the winding roller 1 and is fixed to the frame.
  • this pivotable connection is carried out similarly to the pivotable connection between the lower edge of the guide plate 13 and the lower part 6 of the pliers:
  • the element 16 fixed to the frame consists of at least one axis, which is mounted in at least one body 17 fastened to the guide plate 13, which is on the Axis is snapped.
  • the guide plate 13 Between its upper and its lower edge, the guide plate 13 has a line-shaped bending region 18 which is approximately parallel to these edges and in which the thickness of the guide plate 13 is reduced.
  • the bending area 18 of the guide plate 13 is shown on a larger scale in FIG. 3.
  • the bending area 18 is formed by a recess or groove 19. This is preferably located as shown in the back of the guide plate 13 facing away from the cotton, so that the front of the guide plate 13 guiding the cotton is completely smooth.
  • FIG. 4 A section of a guide plate 13.1 in which the bending area 18.1 is formed by two such depressions 20 and 21 is shown in FIG. 4.
  • FIG. 4 also shows that a fabric strip 22 can be cast into the guide plate 13.1 in the bending area 18.1 as a reinforcing insert, which does not impair the flexibility in the bending area 18.1.
  • a fabric strip 22 can be cast into the guide plate 13.1 in the bending area 18.1 as a reinforcing insert, which does not impair the flexibility in the bending area 18.1.
  • a reinforcing fabric may be present in the bending area 18 3 such a reinforcing fabric may be present.
  • the guide plate 13 can suitably consist of fiber-reinforced plastic.
  • the reinforcing fibers in the bending area 18 (or 18.1) should preferably not be interrupted by the recess 19 (or 20, 21), which means that the recess 19 (or 20, 21) cannot be machined by the guide plate 13 ( or 13.1), but by embossing or pressing the recess into the guide plate before the fiber-reinforced plastic has completely hardened.
  • FIG. 5 shows a variant, in a view corresponding to a section from FIG. 1, in which the guide plate 13.2 not only has the bending region 18, but also a second, identically designed bending region 23 at its upper edge.
  • the upper part of the guide plate 13.2, between the bending areas 18 and 23, is connected in an articulated manner to the upper edge section of the guide plate by the bending area 23, so that this upper edge section can be fixed immovably to an element 16.1 fixed to the frame.
  • the guide plate 13 (or 13.1 or 13.2) could also have an additional bending area configured in the same way as the bending area 18 (or 18.1) at its lower edge, the lower edge section of the guide plate then under the additional bending area with the pliers lower part 6 could be immovably connected.
