Definitions

  • ABSTRACT Textile fiber formed as a compacted bale is loosened, stripped from the bale and rolled into a convolutely wound package in preparation for delivery for subsequent processing. Loosening, stripping and rolling are accomplished by compound motion of the tines of a rake, with the tines having relatively fast movement in a closed path of travel generally about a center of movement and with a lower reach in which the tines move in one direction and the rake having relatively slow movement in the one direction, such that repeated relatively quick strokes of the tines cooperate with the slower movement of the rake for stripping and rolling the textile fiber.
  • Yet a further object of this invention is to avoid the difficulties and deficiencies heretofore encountered in efforts to accomplish removal of the textile fiber from a compacted ball by use of mechanical means.
  • a particularly distinctive compound motion is imparted to the tines of a rake.
  • Yet a further object of this invention is to facilitate the blending oftcxtilc fiber from a plurality of bales. by coordinating delivery of relatively uniform weights of such fiber from a plurality of bales.
  • a plurality of rakes are provided and arranged for cooperation one with another. Furthcr. bales from which fiber is loosened. stripped and rolled are moved relative to thecorresponding rakes in increments of movement. As a result. layers of fibers of generally known and uniform vveight are removed and delivered from a plurality of bales in a particular sequence. By controlling materials of the corresponding bales, the resulting blends of fibers may be determined.

It is believed that an adequate understanding of these processes. if necessary, may be gained from prior patents and publications relating to the textile field generally.
  • textile fiber is raked from a compacted bale B while being loosened in preparation for further processing in accordance with a method which includes the steps of moving the tines ofa rake with a compound motion and relative to the bale of fiber.
  • the compound motion of the tines includes a relatively fast movement of the tines in a closed path of travel generally about a center of movement, the closed path having a lower reach in which the tines move in one direction.
  • raking across the face of the bale causes loosening, stripping and rolling of the fiber as will be described more fully hereinafter.
  • FIG. 3 The path of movement followed by the tines of the rake. in accordance with this invention, is indicated generally in FIG. 3, where a range of positions of a tine is indicated in phantom lines.
  • the tine 20 depends from a generally horizontal rake bar 21, which extends across the lower ends of two pivoting members 22, 24 (FIGS. 5, 13) which form portions of a moving or drive means described hereinafter.
  • the points 25 describe a generally ovoid path (indicated by arrows in FIG. 3) about a center of movement generally indicated at 26.
  • the generally ovoid path is such that the points 25 move along a lower reach of the path in one particular direction (to the left in FIG. 3). At the same time, there is a relatively slow movement of the center of movement 26 in the same direction.
  • the rake means including the tines 20 is supported by a frame means which assures a particular cooperative relationship between the rake means and a bale B from which fiber is to be removed.
  • the frame means generally indicated in FIG. I at 30, includes structural elements which define a generally upstanding housing having corner posts 31, 32, 33, 34. Extending between the corner posts are horizontal support members 36, 37, 38, 39.

  • the carriage subframe mounts a first drive motor 47, for imparting relatively fast movement to the tines as described hereinabove. and a second drive motor 48, for imparting relatively slow movement as mentioned hereinbefore.
  • driving interconnections such as chains 49 and a cross shaft 50, the first drive rotates a pair of eccentric disks 54, 55.
  • a first eccentric disk 54 is connected, at a point spaced from its center of rotation about the drive shaft 50, with a driving link 56 which is pivotally connected to a first pivoting member 58.
  • the pivoting member 58 constitutes a subframe formed by side members 59, 60, supported for pivotal movement relative to the carriage subframe about a pivot shaft 61.
  • the pivotal movement of the member 58 about the axis defined by the shaft 51 imparts vertical movement to the tines 20 of the rake means, thereby determining the extent of vertical displacement between the lower reach of the ovoid path illustrated in FIG. 3 and the highest point thereof.
  • the members 22, 24 are mounted of the first pivoting member 58 for movement therewith about the pivot axis 61.
  • the members 22, 24 function as second pivoting members, and move about an axis defined by a pivot shaft 62.
  • the second pivoting members are driven by a link which connects one member 24 with the other eccentric disk (FIGS. 5 and 10).
  • the particular path described by the points 25 of the tines 20 may be determined and may be optimized for the textile fiber being handled. It is contemplated that the preferred form of path for handling cotton and polyester fibers would be as indicated in FIG. 3.
  • the second drive motor 48 is connected through suitable transmission means including chains 80, 81 and a reducing gear 82 for driving one support shaft 76 in rotation. With such rotational driving of the support shaft 76, the corresponding sprockets 70. 71 are displaced along the corresponding chains 68, 69 and the carriage subframe is slowly moved rela tive to the frame of the apparatus. During loosening, stripping and rolling of fiber as described more fully hereinafter. such motion is in the same direction as the rriotion of the points of the tines 20 along the lower reach of the path illustrated in FIG. 3.

  • corresponding elements of the second rake means and the drive means therefor have been identified by reference characters applied to the elements of the first rake means in the description above, with the addition of prime notation.
  • the tines 20' of the second rake means are moved with a compound motion through the cooperation therewith of linkage members 58, 24' and eccentric disks 54', 55'.
  • the compound movement of the first and second rakes are coordinated.
  • the carriage from which the first and second rakes are mounted alternates in movement (from side to side in FIGS. 4 and 5).
  • the fibers in a layer adjacent one face of one bale are loosened, stripped and rolled by engagement with the corresponding one of the rake means while the fibers of the other bale are loosened in preparation for subsequent stripping and rolling.
  • This operation is made more clear in FIG. 4, where the second rake (to the left in FIG. 4) is shown loosening, stripping and rolling a layer of the fibers from the corresponding bale while the first rake has delivered a convolutely wound layer of fiber L onto a hor izontal run of an endless conveyor belt 86 interposed between the bales B.
  • the conveyor belt 86 is supported by the appropriate frame members 87, 88 and has an uprising trough formed by spaced walls 90, 91 to aid in guiding rolled fiber layers onto the surface of the belt 86.
  • the belt 86 delivers the rolled layers L into a hopper or other suitable rcceiving means for a subsequent fiber processing apparatus.
  • the carriage from which the first and second rakes are mounted is moved in alternate directions. Movement of the carriage is controlled in accordance with the position of the rakes, so that carriage to a position at which the first rake is beyond the corresponding first bale is sensed and the direction of the carriage is reversed in response to such sensed movement. In this manner, alternate loosening, stripping and rolling of layers from the first and second bales is continued while the alternate rolled, stripped layers are delivered to the conveyor. It is noted that the relatively quick movement of the tines in a closed path of travel continues during relatively slow movement of the rake in the direction opposite to the directions of the tines along the lower reach of the closed path. Such compound reverse movement may be employcd, in certain embodiments of this invention, to preloosen fiber in a layer adjacent the face of the bale.
  • this invention contemplates further relative movement between the ral-tcs and the bales from which fiber is to be removed.
  • this invention contemplates periodic displacement of a bale toward a corresponding rake.
  • bales are lifted from a position underlying the rake.

  • the lifting chain 110 is given a looped configuration, having a fixed upper end and passing about a sprocket 112 at the upper horizontal member 101 of lifting frame. As lifting of the frame occurs. chain is delivered into a-storage bin 113 (FIGS. 6 and 8). Coupling ofa bale platform 95 to the lifting frame is accomplished by a side standard defined by vertical members 116, 117 and upper member 118. Each of the vertical members 116, 117 has a hanger bracket 120 adjacent the upper end thereof, which is adapted to be slipped over and engage a hanger hook 121 on a corresponding vertical member 102, 103 ofa lifting frame.

  • the second drive motor 48 provision is made for reversing the direction of rotation of that motor upon sensed movement of the rake means beyond the corresponding bales. This is accomplished by first and second direction control relays 140, 141. In the operating condition illustrated, the first direction controlling relay 140 is energized, to close the associated contact sets 14011, 14012 and cause movement of the carriage in the direction indicated by the arrow (to the right in FIG.
  • Reversal of the direction of movement occurs through the operation of the reversing switch 144, moving with the carriage and arranged to engage appropriate actuating stop members at opposite extremes of the movement of the carriage. That is, upon movement of the carriage to the extreme position desired (such to the right in FIG. 15), an operating rod of the reversing switch 144 engages a stop and is pushed to alternate position (to the left in FIG. 15), deenergizing the first direction control relay 140 and energizing the second direction control relay 141. As a result, the contact sets 141a, [4112 of the second direction control relay 141 are closed and the direction of rotation of the drive motor 48 is reversed. I
