Definitions

  • the invention relates to an opening device for opening pressed fiber bales, for. B. cotton and rayon bales u. Like., According to the preamble of claim 1.
  • the direction of rotation of the opening rollers in the region of the surface of the fiber bale is directed outwards.
  • Each opening roller is assigned its own grate, the open ends of the grate bars facing away from one another, i.e. are directed outwards.
  • the inward grating ends between the opening rollers are mechanically connected to each other by an element, i.e. the inner grate ends are not open.
  • 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 and which is structurally simpler.
  • the fact that the end regions of the grids lying opposite one another are open and are not mechanically connected to one another by an element, as in the known case, means that the removal of the fiber flakes takes place freely and without obstruction by an element, so that a blockage of the machine is avoided.
  • the inward direction of rotation of the opening rollers has the advantage that the removed fiber material is brought together and thrown off together into a single suction channel. During this removal through the middle between the opening rollers, the fiber material is advantageously deflected only once.
  • 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 approximately 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 exerts 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 (peripheral zones) and the inner zone cushioned differently hard.
  • a suction device for the detached fiber flakes is preferably provided above the open ends of the grate bars.
  • the grates are assigned at least two pressure or retention rollers which engage with the surface of the fiber bale, the pressure or retention rollers are in each case on the sides of the gratings facing away from the open grate ends ( Outsides) arranged.
  • 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 rollers) 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 la of the fiber bales 1, whereby hold-down devices are formed.
  • pressure rollers 8a, 8b back-up or retention drums
  • the fiber bales 1 are held stationary and secured against shifting and tipping over.
  • the layers or layers of the fiber bale 1 are secured against horizontal tearing away by the opening rollers or pushing away through the grids 3, 4.
  • the direction of rotation of the milling drums 5, 6, which is denoted by arrows C and D, is directed inward in the region of the surface 1a of the fiber bale 1.
  • the flake suction device 7 is arranged above the milling drums 5, 6.
  • 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 a 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 ⁇ , the central regions 3", 4 "lie essentially horizontally on the surface 1a, the second ends 3"', 4 "
  • 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 a grate of its own 3 and 4 assigned, the open ends 3 ', 4' of the grate bars 3a to 3c; 4a to 4c 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 1a 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 1 a 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.
