Definitions

  • the invention relates to an opening device for opening pressed fiber bales, for. B. cotton and rayon bales u.
  • the opening disks or needles containing fast-opening rollers are provided and engage with a grate, the grate bars between the opening disks z. B. toothed washers or needles, the opening device and the fiber bale brush past each other and the teeth of the opening washers or the needles engage in the fiber bale.
  • the invention is based on the object of creating a device of the type described which avoids the disadvantages mentioned, in which in particular the removal effect is significantly improved.
  • the grate bars of the grates are aligned according to the invention in the direction of movement.
  • the fact that the open end regions of the grate bars protrude upwards at an angle from the surface of the fiber bale has the advantage that the device can travel in two directions, the open end of a grate pointing in the working direction sliding over the bale surface without being undesirable to chop.
  • the grate bars of the grates are preferably arranged offset from one another with respect to the direction of movement of the opening device. This prevents unwanted peaks and furrows in the bale surface in the working direction.
  • the spacing of the offset grate bars transverse to the direction of movement of the opening device is preferably up to approximately 100 mm.
  • the open ends of the grate bars are advantageously arranged to overlap one another.
  • the distance between the ends of the grate bars in an overlapped arrangement is expediently up to approximately 40 mm.
  • the angle between the end regions of the grate bars and the horizontal is preferably approximately 35 ° to 45 °.
  • the length of the essentially horizontal region of the grate bars preferably corresponds approximately to the diameter of the roller base body.
  • the horizontal area is advantageously about 50 to 70 mm long.
  • the open end area of the grate bars is expediently approx. 60 to 80 mm long.
  • a roller is preferably present between the open ends of the grate bars and cooperates with the surface of the fiber bales. This roller presses on the surface of the fiber bale and thereby performs a support and retention function. It is avoided that the fiber bales tip over and that the uppermost layers or layers move undesirably. These are recorded on site.
  • the pressure rollers roll driven or running on the surface of the bale. If the pressure rollers are only present between the ends of the grate bars, the outermost boundary line of the grate bars can expediently run on the opposite side close to the milling drum, so that the device can be inserted in the vertical direction into gaps in the row of bales. This is the case when bales of different heights are arranged directly adjacent to one another.
  • the diameter of the pressure roller is preferably approximately 100 to 150 mm.
  • the pressure roller is advantageously to be provided with needles, teeth or the like (star roller). This ensures a safe intervention in the bale surface.
  • the open ends of the grate bars expediently protrude into the gaps between the needles, teeth or the like of the star roller.
  • the grate bars are preferably individually resiliently attached.
  • Each grate is preferably individually resiliently attached.
  • Each grate advantageously consists of zones with several grate bars and each zone is individually cushioned. At least three zones are expediently provided, the shorter outer zones (edge zones) and the inner zone being cushioned to different degrees.
  • a suction device for the detached fiber flakes is preferably present above the open ends of the grate bars.
  • the grate has at least two pressure or.
  • Retaining rollers are assigned that with the Ob surface of the fiber bales are engaged, the pressure or Retaining rollers are arranged on the sides of the grids (outer sides) facing away from the open grate ends.
  • the fiber bales 1 are set up freely in a fixed bale display.
  • a horizontally reciprocating carriage runs on rails (not shown) to which a vertically adjustable removal device is attached, which consists of a housing 2, two grate halves 3, 4, two milling drums 5, 6 (opening rolls) and a suction device 7.
  • the removal device moves in the direction shown by arrows A and B.
  • the grids 3, 4 engage in the lanes between the teeth 5a, 6a below the milling drum 5, 6 (see FIG. 2).
  • the gratings 3, 4 lie on the surface 1 a of the fiber bale 1, whereby hold-downs are formed.
  • the removal device moves back and forth with the milling drums 5, 6 above the freely installed fiber bales 1, the teeth 5a, 6a of the milling drums 5, 6 reaching through the gaps between the grids 3 and 4, respectively.
  • the fiber flakes detached from the surface 1 of the fiber bales 1 are thrown inwards by the milling drums 5, 6. They go directly into the air flow 9 and are sucked off into the channel of the flake suction device 7.
  • the grids 3, 4 are formed from a plurality of grate bars or grate bars (3a to 3c; 4a to 4c; see FIG. 2).
  • Each grate bar consists essentially of three areas: a first end 3 '; 4 ', a central area 3 "; 4" and a second end 3, 3'; 4 "'.
  • the first ends 3', 4 'protrude from the surface 1a at an angle a, the middle regions 3", 4 "lie essentially horizontally on the surface 1a, the second ends 3", 4' ' 'protrude from the surface 1 at an angle.
  • the ends 3 ', 4' are open; at the ends 3 "', 4" the grate bars are fastened to holding elements 10a, 10b.
  • Each opening roller 5, 6 is assigned its own grate 3 or 4, the open ends 3 ', 4' of the grate bars 3a to 3c; 4a to 4c are facing each other.
  • the milling drums 5, 6 are shown schematically between the grate bars 3a to 3c and 4a to 4c, the area of their action on the surface 1 being drawn in dash-dot lines during their rotation.
  • the grate bars 3a to 3c and 4a to 4c are arranged offset to one another in the lateral direction. As a result, the furrow formed by a grate bar on the bale surface 1a can be worked off by a milling drum 5 or 6 opposite in the working direction.
  • the outer ends 3 ", 4" of the grate bars 3a to 3c and 4a to 4c are fastened to a common holding element 10a or 10b which is attached to the side walls 13 (14 not shown) of the housing 2.
  • the external ends 3 ", 4" of the grids 3, 4 are at a distance from the milling drums 5, 6.
  • the distance a, the offset grate bars 3a to 3c or 4a to 4c transverse to the direction of movement A, B of the opening device is approximately 100 mm .
  • the distance b between the ends 3 ', 4' of the grate bars 3a to 3c or 4a to 4c in an overlapped arrangement is approximately 40 mm.
  • the open ends 3 ', 4' of the grate bars 3a and 4a are arranged to overlap one another.
  • the distance between the overlap and the bale surface 1 is designated c.
  • the angle between the central horizontal area 3 "of the grate bar 3a and the end area 3 ' is designated by a.
  • the angle between the horizontal area 4" of the grate bar 4a or the bale surface 1a and the open end area 4' corresponds to the same angle a.
  • Fig. 4 shows the resilient suspension of the grate 3.
  • the grate 4 is suspended in the same way.
  • the grate bars 3a, 3b, 3c are attached to the holding element 10a, which is resiliently attached to a support element 12 via springs 11a, 11b is.
  • the grate bars 3a to 3c form an outer zone 1, which is followed by a central zone 11. Zone 11 can be cushioned differently from zone I.
  • a pressure roller 8c provided with teeth 8 ' is present between the open ends 3', 4 'of the grate bars 3a, 4a.
  • the outermost boundary line of the grate bars 3a, 4a in the region of the second end 3m or 4 "runs near the milling drum 5 or 6 so that the device can be inserted in the vertical direction in gaps between the bales 1 of a row of bales.
  • the corners between adjacent ones Bale 1 can be processed.
  • FIG. 6 shows an embodiment in which there are two external pressure rollers 8a, 8b and an internal pressure roller 8b.
  • the pressure or Retaining rollers 8a to 8c have the advantageous effect that both the layers or layers of the fiber bale 1 and the entire fiber bale 1 are not shifted in an undesirable manner.
  • Each opening roller 5, 6 is assigned its own grate 3, 4.
  • a separate grate 3, 4 is to be understood that the grids 3 and 4 are independent of one another, i. that is, between the open, facing (opposite) ends 3 ', 4' of the grate bars 3a to 3c; 4 a to 4c, there is a gap e (in the longitudinal direction) and / or f (in the transverse direction).
