Definitions

  • a device for removing tufts of fibers from a compressed bale of textile fibers comprises an opener roller with teeth on its periphery to remove the fiber flocks and convert them to the desired flocculent form.
  • a back-stripper roller then removes the insufficiently opened flocks from the opener roller after which the opened flocks are removed from the opener roller by a stripper roller.
  • the insufficiently opened flocks are returned to the opener roller where they are compressed by an oscillating panel against the opener roller causing the teeth on the opener roller to again take up and flocculate the insufficiently opened flocks.
  • bales are opened at the top with the device being continuously lowered as the disintegration progresses.
  • the device is raised and moved laterally whereupon the flocks can drop away.
  • open spaces must be left between the bales in a row to permit the flocks to drop onto a conveyor belt lying therebeneath.
  • bale In other devices the bale is disintegrated laterally from one side to the other. Difficulties arise with this arrangement since as the device approaches the opposite side of the bale the remainder of the bale becomes unstable so that regular removal of uniform amounts of flock material cannot be maintained.
  • bales are pressed upwardly against a device which consists of a spiked belt.
  • the difficulty with this arrangement is that the device is generally suitable for loosening only a single bale as the spiked belt clogs, and the following bales in a row can no longer be uniformly disintegrated without first clearing the flocks from the spiked belt.
  • An object of the present invention is to provide an device for disintegrating a compressed bale of textile fibers and to dispense flocks of uniform and sufficient openness.
  • Another object of the present invention is to provide an device which will selectively separate insufficiently opened flocks from sufficiently opened flocks and recyvide a device which may be maintained in continuous operation without shutdown to clear away jammed flocks.
  • a further object of the present invention is to provide a device in which the degree of openness of the flocks may be controlled and maintained uniform.
  • a still further object of the present invention is to provide an device capable of controlling the rate at which a compressed bale is fed towards the device whereby the device may be maintained at full operating capacity but not overloaded.
  • the device for disintegrating a compressed bale of textile fibers comprises a rotatably mounted opener roller having a plurality of opener teeth mounted on the cylindrical surface thereof with means to progressively feed a bale of the fibers towards and against the opener roller.
  • the opener rotates the teeth dig into the surface of the bale and continuously remove and at least partially open flocks.
  • a backstripper roller is located adjacent the opener roller opposite the location of the bale and has teeth thereon which selectively remove the insufliciently opened flocks from the teeth of the opener roller as both the back-stripper and opener rollers rotate. Fully opened flocks still retained on the opener roller are then removed by a stripper roller.
  • the insufficiently opened flocks are removed from the teeth of the back-stripping roller by a cleaning roller and are then allowed to fall downwardly and to accumulate between the opener roller and an oscillating panel. Compression of the accumulated insufficiently opened flocks by the panel against the opener roller causes the insufficiently opened flocks adjacent the opener roller to be again caught by the opener teeth which completely opens the flocks. The result is that all of the flocks removed from the compressed bale by the stripper roller are in the desired flocculent form before being dispensed from the device.
  • FIG. 1 is a side elevation in cross-section of the unraveling device including the bale feed mechanism
  • FIG. 2 is a fragmentary cross-sectional view taken along the line 11-11 of FIG. 1;
  • FIG. 3 is a fragmentary cross-sectional view taken along the line III-Ill of FIG. 1;
  • FIG. 4 is a fragmentary cross-sectional view taken along the line IVIV of FIG. 1.
  • the unravelling device shown generally at 1 includes a vertical shaft 2 for accommodating a bale 3 of textile material.
  • the bale rests on a platform 4 which is arranged to be raised and lowered on rotatably driven externally threaded spindles 5 and 6.
  • the spindles are driven by a motor 7 through transmission 8 and gear 10 attached to the end of the shaft 9 from the transmission.
  • Gear 11 is secured to the base of spindle 5 and meshes with driven gear 10.
  • Gear 12 which corresponds to gear 1 1 and is secured to spindle 6 is driven simultaneously with'gear 11 through an intermediate transmission means shown generally at 38 which may be for example a chain or toothed-belt drive.
  • An opener roller 14 is centrally located at the top end of shaft 2 in casing 13.
  • Cooperating rollers also contained in case 13 include a back-stripping roller 15 with which a cleaning roller 17 is associated and a stripper roller 16.
  • the cylindrical surface of the opener roller 14 includes rows of opener teeth 1421 which project in a forward direction with respect to the direction of rotation of the opener roller as indicated by arrow 39.
  • the teeth 14a will penetrate the top surface of the bale 3 and remove the compressed flocks. During their removal the flocks tend to be opened or flocculated.
  • the flocks impaled on the opener teeth 14a reach the back-stripping teeth, many of the flocks will have been flocculated to the desired extent while other flocks will not be sufficiently opened.
  • Back-stripping roller 15 includes radially extending teeth 15a which are arranged such that as the back-stripping roller 15 rotates in the same direction (arrow 40) as opener roller 14 the insufficiently opened flocks are selectively removed from the opener roller 14, the fuller opened flocks remaining on the roller 14 and being removed by stripper teeth 16a on stripper roller 16.
  • the stripper roller rotates in the opposite direction (arrow 41) from opener roller 14 and dispenses the opened flocks 36 onto conveyor 37.
  • the extent of expansion of the flocks can be controlled by adjustment of the distance between opener roller 14 and back-stripping roller 15 as indicated by arrow 19. By adjusting this distance, the density of the flocks which are permitted to remain on opener roller 14 and to be removed by stripper roller 16 can be controlled, and all flocks having a heavier density than desired are removed by back-stripping teeth 15a. Also, the distance between stripper roller 16 and opener roller 1% may be controlled as indicated by arrow 18 whereby the removal of all flocks from the opener roller 14 can be assured.
  • the insufficiently opened flocks removed from opener roller 14 are carried upwardly on backstripping teeth 15a until they are removed by the cleaning teeth 17a on cleaning roller 17 which rotates in the same direction as back-stripping roller 15 as indicated by arrow 42.
  • the insufficiently opened flocks are deposited and accumulate in gathering space 21.
  • the gathering space is defined by the opener roller 14, back-stripping roller 15, cleaning roller 17, a guide plate 33, a shaker panel 20, and a curved box wall 35.
  • the partially opened flocks are precipitated into the lower portion of the gathering space 21 where they are compressed intermittently by shaker panel 20. With each compression the partially opened flocks contiguous to the opener roller 14 are again impaled on opener teeth 14a and are flocculated as the opener roller rotates.
  • Shaker panel 20 is pivotally mounted on shaft 22 which is secured in casing 13.
  • the free end of shaker panel 20 includes a sealing strip 34 which contacts the interior surface of curved box wall 35 and insures that the flocks will remain to the left of the shaker panel 20.
  • the shaker panel is oscillated by connecting rod 23 which is pivotally connected at one end to the shaker panel at 24 and at the opposite end to disk 26 by a bolt 25 slidably secured in slot 29.
  • Belt 27 drives the disk 26 through pulley 28 giving an eccentric drive to the connecting rod 23.
  • the connecting rod 23 includes biased resilient means for extending the rod length automatically depending upon the volume of the accumulated flocks retained between the shaker panel 20 and the surface of opener roller 14.
  • the resilient means includes cylinder 23a in which a piston rod 23c and piston 23b are located.
  • a spring 23c is retained on the piston rod 230 between the piston 23b and collar 23d mounted on the cylinder 23a and through which the piston rod 230 slides.
  • a sensor 31 is located in a wall of the gathering space 21 which may advantageously be of the ultrasonic type so that the degree to which the gathering space 211 is filled can be sensed.
  • the sensor 31 is connected by electrical cable 32 to motor 7 and serves to regulate the speed of motor 7 depending upon the amount of flock material contained in the gathering space.
  • the motor will operate at a higher speed causing the bale 3 to be moved upwardly at a faster rate and increasing not only the rate at which the opened flocks 36 is dispensed but also increasing the accumulation of insufficiently opened flocks in the gathering space 21.
  • the sensor 31 will cause motor 7 to slow down to reduce the rate at which the bale 3 is fed upwardly and assure that the gathering space will not become overly filled with insufficiently opened flocks.
  • bales can be disintegrated to the point where only a negligible amount, e.g., to 300 grams, remains on the platform 4.
  • a recessed top surface in the platform 4 permits the opener roller 14 to remove nearly all of the flocks.
  • each of the devices may be equipped with an automatic weighing device, thus serving to feed predetermined relative amounts by weight of the various fibers in a constant ratio.
  • a device for removing tufts of textile fibers from a compressed bale and dispensing said tufts of fibers comprising a. a rotatably mounted opener roller having a plurality of opener teeth mounted on the cylindrical surface thereof to remove and open flocks from said bale,
