Definitions

  • the invention relates to a method and an apparatus for removing fiber flakes from fiber bales arranged in series, e.g. Cotton or synthetic fiber bales and the like, by means of a removal member traveling over the fiber bales with at least two rotating removal rollers according to the preamble of the 1st and 2nd process and 7th, 10th and 17th device claims.
  • a removal member traveling over the fiber bales with at least two rotating removal rollers according to the preamble of the 1st and 2nd process and 7th, 10th and 17th device claims.
  • the removal member penetrates the fiber bales with a predetermined penetration depth each time it is passed over, in order to give the removal rollers the opportunity to detach fiber flakes from the surface, which then transfer them to a pneumatic conveyor shaft will.
  • the axes of the removal rollers are arranged horizontally.
  • they are designed according to DE-A-33 34 069 as toothed disks, which - as seen in the direction of the axis of rotation of the removal rollers - are lined up with gaps between the toothed disks which lie on the surface of the fiber bales when the fiber flakes are removed.
  • the removal rollers rotate in opposite directions, the front removal roller viewed in the direction of travel rotating in the so-called synchronism with the direction of travel in order to detach the fiber flakes from the surface in this synchronization.
  • the rear roller seen in the direction of travel rotates in the opposite direction and loosens fiber flakes from the same surface in the counter-milling system.
  • Removal elements with an opening roller are also known, the direction of rotation of which is reversible, so that the opening roller can be rotated in the direction of synchronization.
  • An improvement in the abovementioned removal performance consists in the possibility of having both removal rollers rotate in the same direction in each direction of travel, which, however, means that the rollers are given an opposite direction of rotation for the return trip or that the removal member is lifted from the surface, so that fiber flakes only can be triggered in one direction.
  • the increase in output is somewhat problematic even with a rapid return trip, since, depending on the length of the bale rows, a time interval must be accepted during which no fiber flakes are released.
  • Another means of increasing the performance is known to be to increase the length of the roll accordingly, with removal elements which have a single roll or two rolls.
  • both rollers can utilize the full removal depth, so that the removal capacity is effectively doubled in a two-roller arrangement, or, on the other hand, smaller flakes are removed with an removal capacity equivalent to a roller can be, since it is known that the flake size increases with increasing depth of penetration per crossing, which is not always desirable.
  • a double or multiple roller arrangement can be used to achieve a double or multiple output compared to a single roller arrangement with the same penetration depth, or there is the possibility of reducing the flake size by reducing the penetration depth for a given output.
  • a device 1 for removing fiber flakes comprises a stand 2, which travels along a row of bales 4 by means of wheels 3 on rails (not shown), in the direction A shown in FIG. 1 and in the direction B shown in FIG. 2
  • a removal member 5 on guide rails (not shown) in accordance with the arrows C and D. arranged up and down movable.
  • the removal member 5 has two rotating removal rollers 6a and 6b, which are known, for example, from the European patent application EP-A-58781. From this patent application it is known that these removal rollers consist of a series of toothed disks with gaps between the disks.
  • the removal rollers 6a and 6b are each in a roller carrier 8 and 9 rotatably and drivably mounted.
  • This roller carrier 8, respectively. 9 are in turn guided in the removal member 5 by means of slide rails (not shown), movable up and down according to the arrow directions C and D, this movement being carried out by means of an actuator drive 10 (FIG. 2).
  • a drive comprises a geared motor 12 with a rotation pulse generator 13 attached to the removal member 5 by means of a bracket 11 (FIG. 1).
  • the output shaft of the geared motor is at the same time a spindle 14 which is guided in a spindle sleeve 15.
  • the spindle sleeve is in turn on the roller carrier 8, respectively. 9 attached.
  • the roller carrier 8, respectively. 9 each further comprise a baffle plate 16 and 17 (FIG. 2), which open up into an outlet channel 18, as viewed in the figures.
  • a suction channel 19 resp. 20 with a minimal play between the respective suction channel and the outlet channel 18 in order to generate in the vicinity of the removal rollers the negative pressure necessary for the suction of the fiber flock conveying air.
  • the outlet channels 18 and the suction channels 19, respectively. 20 extend at least over the entire length of the removal rollers 6a, respectively. 6b, ie cover them Removal rollers.
  • the suction channels 19 and 20 are connected to a suction pipe 21, which in turn is connected to a vacuum source (not shown) in order to generate the aforementioned fiber flock conveying air flow.
  • the suction pipe is designed conically, in such a way that it increasingly has a larger diameter against the vacuum generator in order to obtain an essentially uniform amount of air sucked off over the entire length of the removal rolls.
  • the vacuum source is known per se from practice and is therefore not explained in more detail.
  • the removal member 5 could be modified such that not the entire removal member can be moved up and down, but only the roller carriers 8 and 9. Accordingly, the outlet channel 18 and the suction channel 19 or. 20 should be designed telescopically, and the spindle 14 would have to undergo a corresponding extension.
  • the removal member 5 as such would be arranged stationary in such a variant.
  • the grate bars 7 are also a component of the roller carrier 8 or in the case of the latter variant. 9, wherein these grate bars, as shown in Fig. 5, or as shown in Fig. 6, are attachable.
  • FIGS. 3, 4, 6 and 7 show a variant according to the invention, in which the same elements of FIGS. 1 and 2 have the same reference symbols.
  • This variant shows a device 1.1 for removing fiber flakes with the stand 2, but with a removal member 30, in which the rotatable and driven Removal rollers 6a and 6b are arranged stationary with respect to the removal member.
  • the removal member 30 is pivotally mounted as a whole by means of a hollow pivot axis 31, which rotates about an axis of rotation 39.
  • the pivot axis 31 is received by a rotary bearing 43 (FIG. 7) provided in a sliding carriage 40.
  • the means for moving the slide 40 up and down are described in EP-A 193647.
  • grate bars 32 are fastened either in the manner shown in FIG. 5 or in the manner shown in FIG. 6.
  • the removal member 30 is pivoted about the axis of rotation 39 by means of an actuator drive 33 (FIG. 6).
  • This comprises a geared motor 34 which is pivotally attached to a sliding element 35 which can be moved up and down with the removal member, in accordance with the directions of movement C and D. This is guided through a stationary guide tube 41.
  • the sliding element 35 is carried along for the movements in the aforementioned directions by a driver 42 which is fixedly arranged on the one hand on the sliding element 35 and on the other hand on the sliding carriage 40.
  • the output shaft of the geared motor is provided as a spindle 36 which is guided in a spindle sleeve 37.
  • the spindle sleeve is in turn pivotally attached to the removal member 30 by means of a pivot bearing 38.
  • the removal member 30 for guiding the air flow promoting fiber flakes also includes an air duct, which, according to its functions, extends over at least the entire length of the removal rollers 6a resp. 6b extends and is connected to a suction pipe which, in turn, is connected to a vacuum source (not shown) in order to generate the air flow mentioned.
  • the grate bars 32.1 shown in Fig. 5 are attached to side members 50, which in turn by means of a pivotally attached lifting mechanism relative to the removal rollers 6a and. 6b are movable.
  • the lifting mechanism comprises the gear stop motors 51 shown in the aforementioned European patent application and the threaded spindles 52.
  • the spindles 52 are guided in spindle sleeves 53, which are pivotally connected to the side members 50.
  • the gear stop motors are equipped with rotation pulse generators 54, with which the position of the removal grates 32.1 can be specified in a controller (not shown). Such controls are known per se.
  • removal member 30.1 of FIG. 5 can be provided in the same way with a pivoting mechanism shown in FIG. 6 and can be pivoted in the same way about the axis of rotation 39, without this again in detail mention.
  • FIGS. 8 to 11 show different operating variants which can be carried out with the devices shown hitherto.
  • FIG. 8 shows the possible uses of the removal member 30 (FIG. 6) and 30.1 (FIG. 5).
  • the pivoting angle ⁇ .1 of the removal rollers 6a and 6b resulting from the pivoting of this removal member has the same size as the pivoting angle ⁇ .1 of the grate bars 32.
  • the angle ⁇ .1 is assumed to be one Plane 56, which bears against the circumference of the removal rollers 6a and 6b, and on the other hand the angle ⁇ .1 is formed by the plane 55 and an imaginary plane 57, which contains the lower surface of the grate bars which dips into the bale surface.
  • the swivel angle ⁇ .1 is generally chosen such that the depth of penetration T.1 of the removal roller 6a is approximately half the depth of penetration T.2 of the removal roller 6b.
  • the penetration depth is understood to mean the degree of penetration of the respective removal roller relative to the bale surface in front of the removal member 30. This applies regardless of whether the stand moves in direction A (Fig. 3) or in direction B (Fig. 4).
  • the angle ⁇ is equal to the angle ⁇ .
  • Fig. 9 shows the same, but for the direction of travel B. Therefore, what has been said for the angles ⁇ .1 and ⁇ .1 also applies to the angles ⁇ .2 and ⁇ .2.
  • the suspension of the grate bars 32.1 of FIG. 5 is combined with a pivotable removal member, according to the removal member 30 of FIG. 6, it is possible to angle ⁇ .1 or ⁇ .2 and ⁇ .2 (FIG . 8) to choose differently.
  • FIG. 10 shows an example with the use of the removal member 30.1, that is to say without a pivoting mechanism, that is to say only with an adjustment possibility of the grate bars 32.1, so that the difference in the penetration depth T.3 between the removal roller 6a and the removal roller 6b by adjusting the Grate bars 32.1 with the angle ⁇ .3 for the direction of travel A and with the angle ⁇ .4 for the direction of travel B are produced.
  • the directions of rotation G and H or K and L (K and L not shown in FIG. 10) can be selected.
  • FIG. 10 shows the use of the removal member 5 according to FIGS. 1 and 2, but only for the direction of travel A.
  • the penetration depths T.1 and T.2 can be selected individually and can accordingly be shown in the return trip B (not shown in FIG. 10) ) take place alternately, provided flakes are removed in both directions of travel.
  • the arrow B shown with dashed lines and the row of balls 4 shown with dashed lines indicate a variant which is possible with all removal means, namely that on the return trip the removal elements 5 and. 30 resp. 30.1 are lifted away from the bale surface and always have the same inclination. In this way, fiber flakes are always removed from the bales only in direction A.
  • This variant can also be used if it is intended to always remove the mixture from the same side within the fiber bale row.
  • a fixed inclined position of the removal rollers can also be selected for such a variant.
  • inventive concept presented in this application can still be combined with the inventive concept shown in European patent application EP-A-0193647.
  • the depth of delivery of the removal member 5 or. 30 resp. 30.1 per passage changed with increasing fiber bale density, i.e. is reduced in size, firstly to make the output uniform and secondly to gently remove the fiber flakes from the fiber bales.
