Definitions

  • the invention relates to a method and a device for opening textile fiber bales, in which a fiber removal element penetrating into the bale surface layer for removing fiber flakes can be moved back and forth over a row of fiber bales at a predetermined displacement speed, and in which the surface layer passes through before removal a compression means provided in front of the fiber removal element, viewed in the direction of displacement, is compressed.
  • the bales are placed in a row on a floor surface in order to use the removal element on the upper surface of the bale to remove flakes which are conveyed on pneumatically.
  • the compacting agent which is advantageous per se, has a disadvantageous effect on the residual removal of the fiber bales in that residues of low heights, e.g. B. 10 cm and less, not clearly detected by the compression means and can be pushed in front of the fiber ablation element.
  • the object of the invention is to remedy this disadvantage.
  • the invention as characterized in the claims, achieves the object procedurally in that the surface layer is promoted in the direction of the fiber removal element in the area of compression.
  • This inventive step not only gave the advantage that the remains of the bale were also conveyed to the removal member, but also that the compaction can be made changeable.
  • the fiber material is advantageously gripped by the conveying means at a point at which a break-out from the surface structure is prevented and is thereby conveyed more positively than without this measure.
  • a removal member 1 (FIG. 1) is arranged in a machine frame 2 (FIG. 2) of a bale removal machine (not shown) which is known per se.
  • This stripping machine is a machine of the applicant traded under the brand name »Unifloc «.
  • the removal member 1 comprises a machine housing 3 with side walls 4 and 5 and a front wall 6.
  • a shaft 7 of a fiber removal roller 8 is rotatably supported on the one hand in a bearing 9 fastened to the machine frame 2 and in a bearing 10 fastened to the front wall 6.
  • toothed disks 11 are oblique, i. H. firmly arranged as swash plates.
  • the toothed disks are suitable for fiber flake removal in both directions of rotation of the toothed disks and protrude through openings 12 of a grate 13 in fiber bale surface layers of fiber bales 14.
  • the grate 13 is fastened on the one hand to the machine frame 2 and on the other hand to the front wall 6.
  • a wall 15 is pivotally arranged by means of hinges 16 connected thereto.
  • the axes of the hinges 16 are each embedded in the front wall 6 and in the machine frame 2.
  • the walls 15 are fixed within a swiveling range a of 10-30 degrees of angle by a tab 18 and 19, which are pressed against each other by means of fixing screws 20.
  • a swiveling range a of 10-30 degrees of angle by a tab 18 and 19, which are pressed against each other by means of fixing screws 20.
  • the tabs 19 are parts of the walls 4, respectively. 5 and the tabs 18 are parts of the walls 15.
  • the tabs 18 and 19 are convex with the same radius, respectively. concave so that they slide against each other when swiveling.
  • the tabs 18 for receiving the fixing screws 20 are provided with threaded holes (not shown).
  • the tabs 19 are provided with a slot 21 per fixing screw 20 (FIG. 4).
  • the removal member each comprises a star roller 22 and 23, (only partially shown in Fig. 2) which by means of a shaft 24 and. 25 in bearings 26 and 26 'respectively. 27 and 27 'are rotatably arranged.
  • star-shaped conveyor disks 28 sit on the shafts 24 and 25 and protrude into the fiber bale surface layer to be compressed through slot-shaped openings 29 provided in the walls 15.
  • the conveyor disks 28, as shown in FIG. 1, are formed by two equilateral triangles tacked together.
  • the bearings 26 and 26 'and the bearings 27 and 27' are, as in FIG. 3 shown for the bearings 27 and 27 ', provided with slots 30 as guide slots for the screws 31 (Fig. 2).
  • This measure serves either to move the star rollers 22 and 23 simultaneously with the walls 15 or to change the immersion depth of the star rollers 22 and 23 in the fiber bale surface layer.
  • the fiber removal roller 8 is driven in the machine area, not shown, which is separated from the machine housing 3 by the machine frame 2.
  • the star rollers 22 and 23 are also driven by a geared motor 33 fixedly mounted on a support 32.
  • a sprocket 34 and a sprocket 35 are fixedly arranged on an elongated shaft 36 of the geared motor 33.
  • a drive chain 38 connects the chain wheel 34 to a chain wheel 39 fixedly arranged on the shaft 24, and a drive chain 40 on the other hand connects the chain wheel 35 to a chain wheel 41 fixedly arranged on the shaft 25.
  • the speed of the star rollers 22 and 23 is selected such that the tips of the toothed disks 11 receive a peripheral speed which is at least 5% and at most 30% higher than the displacement speed of the removal member 1.
  • the peripheral speed is referred to as the conveying speed.
  • a normal conveying speed is 20% higher than the moving speed of the material removal machine.
  • the shifting directions of the removal member are designated V, and V 2 (Fig. 1).
  • the direction of rotation of the star rollers 22 and 23 is rectified and changes in accordance with the direction of displacement such that the front star roller seen in the direction of displacement positively, that is, the fiber bale surface layer. H. promotes against the removal roller 8.
  • FIG 5 and 6 show a variant of the device according to the invention, in which instead of the walls 15 and the star rollers 22 and 23, one in each case in the directions B, pivotally mounted conveyor belt 42 and. 43 is provided.
  • the conveyor belt 42 is guided by the deflection rollers 44 and 45 and the conveyor belt 43 by the deflection rollers 46 and 47.
  • the pulley 44, respectively. 47 is on an axis 48 respectively. 49 pushed on, while the pulley 45 resp. 46 fixed on a shaft 50 respectively. 51 sits.
  • the axis 48 is by a bearing 52 and 53, which can be displaced analogously to the bearings 26 and 27, and the axis 49 by a bearing which can be displaced analogously to the bearing 26 'and 27' 52 'and 53' rotatably mounted.
  • the shaft 50 is rotatably mounted in a bearing 54 and 55 and the shaft 51 in a bearing 54 'and 55'.
  • a chain 58 connects the sprocket 56 to a sprocket 59 non-rotatably connected to the shaft 36 and a sprocket 60 which is also non-rotatably connected to the shaft 36 is connected to the sprocket 57 by a chain 61.
  • the speed of the shafts 50 and 51 is chosen such that the surface speed of the conveyor belts is between 5-35% higher than the displacement speed of the removal member 1.
  • a normal surface speed is approx. 25% higher than the displacement speed of the removal element 1.
  • the direction of rotation of the conveyor belts 42 and 43 is rectified and changes in accordance with the direction of displacement such that the front conveyor belt seen in the direction of displacement, the fiber bale surface layer positive, i. H. promotes against the removal roller 8.
  • FIGS. 5 and 6 which are not shown again correspond to the elements drawn and described with FIGS. 1 and 2.
