Definitions

  • the invention relates to a method and a device for the automatic exchange of full by empty sleeves on a flyer according to the preambles of claims 1, 6 and 11.
  • a known flyer doffing device operates as follows: In the infeed position, empty sleeves hang on a carrier cum transit bar, which sleeves have been transferred to the carrier by the hanging transport device coming from a ring spinning machine. In a vertical downward movement, the carrier places the empty tubes in two longitudinal rows on an intermediate shelf which extends in front of the base and extends parallel to the flyer, that is to say two parallel plates or strips which are fitted with push-on pins and which extend in the longitudinal direction of the flyer can be moved by half a division, and starts up again. The plates shift by half a division related to the placement of the full sleeves in the flyer.
  • the flyer At the middle level of the flyer, the flyer has a horizontal swivel and slide rod that extends over its full effective length and beyond, and a translator can be displaced over the flyer length via this rod.
  • the converter is aligned in the vertical position on the clipboard and can be brought into an inclined position inclined to the flyer by means of a lever construction, in which inclined position it is with the full sleeves to be replaced, which are lowered from the operating or spinning position and tilted into an inclined position is aligned on carriages holding spindles.
  • the converter has twelve holding pins at the end of its lifting cylinder, with which it pulls the full sleeves off the carriage in groups, and places them on the clip-on pins of the clipboard between the empty sleeves already on it.
  • the converter is able to lift the empty sleeves in groups from the clipboard, bring them into an inclined position and put them back on the spindles on the carriage.
  • the carriage with the complete number of empty tubes tilts back into the horizontal position and is lifted vertically into the correct piecing position.
  • the carrier lowers again in order to lift the full sleeves from the clipboard and to convey them vertically into their upper removal position. From this removal position, the full sleeves are repositioned on the transport device by means of a pivotable lever arm, in order to subsequently use ring spinning machines to supply roving bobbins.
  • the object of the present invention to propose a method and a device in which the doffing time can be significantly reduced while simplifying the design and the accessibility of the flyer can be improved.
  • Another important task is to create a retrofit option for adding doffer, which means that existing flyers that are hand-hoped for can be modernized, especially flyers that are equipped with a tilting trolley.
  • the time saved in this way benefits the efficiency of the flyer. By eliminating the clipboard, the flyer will be even more accessible.
  • the inexpensive, space-saving construction of the tiltable trolley can preferably be retained because the drive mechanism does not have to be disconnected.
  • the embodiment according to claim 11 can, however, also be used for a purely vertical mode of operation, for example for flyers whose trolleys are extended with spindles that remain vertical, as was shown, for example, in EP-OS 310 568.
  • the flyer itself does not need to be redesigned, provided that the car is either tiltable or extendable.
  • the doffing time can be shortened again by the features of claims 3 to 5. Unless otherwise stated, everything in this document is to be regarded as inventive.
  • a carrier 21 cum transit bar which extends over the entire length of the action, ie the entire spinning area, of the flyer of a doff device 20 completely separate from the flyer can be moved and / or moved on at least two one-piece slide rails 22 which are angled towards the carriage 6 and supported by profile supports 23 on the ground .
  • Each slide rail 22 has a vertical movement path 15a and an inclined movement path 15b, the inclination corresponding to the inclined position of the carriage 6.
  • FIG. 2 shows an embodiment of an extruded profile of a slide rail 22, where it can be seen how the carrier 21 can be moved on the slide rail 22 by means of rollers 24 on the outside and rollers 25 on the inside of an open web 26 of the slide rail 22 and side guide rollers 27.
  • the carrier 21 has in a conventional manner an endless belt 32 stretched around two deflection rollers 31 and movable by a motor 33. 9 to be explained in the form of plug-in pins 34, which are now spaced apart with respect to the division 35 of the sleeves on the carriage 6 and in the spinning positions, the half division 36, so that the number of Pin 34 is twice the number of spinning stations.
  • the carrier 21 is in the removal position of the full sleeves 10, which is also the transport position of the empty sleeves 11.
  • a known hanging transport device 40 is also arranged and also a pivotable lever arm 41, which the full sleeves 10 from the carrier 21 onto the transport device 40 and the empty sleeves 11 from the transport device 40 onto the carrier 21.
  • Full sleeves must be replaced by empty sleeves.
  • the full sleeves 10 are lowered with the carriage 6 and brought into the inclined position.
  • the empty sleeves 11 on the carrier 21 are in the transport position.
  • the carrier 21 together with the empty sleeves 11 is moved downward, first vertically, then through the angled shape of the slide rails 22 into the inclined position.
  • the empty sleeves 11 are lowered into the inclined position in a continuous movement without intermediate storage.
  • the empty pins 34 of the carrier 21 are aligned with the full sleeves 10.
  • the empty sleeves 11 enter empty spaces 46 between the full sleeves 10 (FIG. 3).
  • the empty pins 34 couple to the full sleeves 10.
  • the lifting mechanism of the carrier 21 has been realized by means of a height-adjustable sliding block 55.
  • the sliding block 55 and a screw rod 57 which is used for height adjustment and is driven by a motor 56, are integrated in a vertical profile support 23a.
  • form-fitting spindles, toothed racks, bands, etc. can also be used.
  • the sliding block 55 has a tab 60 which projects through a longitudinal slot 61 of the profile support 23a.
  • An articulated rod 62 possibly in connection with a cylinder 63, connects the tab 60 to the carrier 21.
  • This alternative embodiment ensures that the carrier 21 is safely moved downward.
  • the cable 42 stretched over the deflection roller 43 can be maintained for the purpose of balancing the weight of the carrier 21.
  • the positions of the side guide rollers 27 are indicated by broken lines within a slide rail 22a that has been slightly modified compared to FIG.
  • FIG. 2 shows a suitable guidance of the carrier 21 on the slide rail 22, 22a.
  • the pins 34 must also are rigidly guided, for example, as shown in Figure 9.
  • the pins 34 are connected to the endless belt 32 via pin holders 68.
  • rollers 25.1 and lateral guide rollers 27.1 are also provided here, which are supported on a profile rail 69. Because of ribs 70 on the profile rail 69 rollers 24.1 are missing.
  • the profile rail 69 advantageously encloses the entire length of the endless belt 32, wherein horizontal recesses 71 are provided for the deflection rollers 31.
  • the pin holders 68 protrude through a continuous slot 72 at the bottom in the profile rail 69.
  • FIG. 10 shows a pin 34.1 with a stiffening or a support means in the form of a possibly interrupted cylindrical jacket 80, which extends partially over the length of the sleeve 10,11.
  • Figure 10 shows a cylindrical jacket 80.1 which can be penetrated into the end face of the sleeve 11.
  • Figure 11 shows a pin 34.2 with a support means in the form of a pressure body 82, which is supported on the end face of the sleeve. The pressure body 82 is held by a spring 83.
  • FIG. 12 shows a pin 34.3, the stiffening of which was inspired by a bottle stopper.
  • Elastic rings 84 on a pin 85 expand on the inside of the sleeve, while extensions 86 on pin 85 are supported on the end face of the sleeve 11.
  • the pin 85 has an annular recess 87 and a spring element 89 which interacts with a square 90 of a bolt 91 which is fixedly but rotatably connected to the pin holder 68 in such a way that the Spring element 89 rotates the square 90 and thus the bolt 91 by 90 degrees when the pin 85 is moved upward. In this way, the pin 85 can be locked and unlocked.
  • a modification is shown in FIG. 13, where the bolt 91.1 is fastened to the pin 85 and the spring element 89.1 to the pin holder 68.
  • FIG. 14 shows a completely different flyer doffing device 20.1, where different parts are shown superimposed.
  • the carrier 21.1 (shown twice) is separated from the fixed or immovable transit bar 95.
  • a sliding block 55.1 can be moved vertically by means of, for example, the screw rod 57.
  • the movement path 15b is articulated and adjustable by means of a hydraulic or pneumatic cylinder 96 with the sliding block 55.1.
  • the carrier 21.1 can be moved on this movement path 15b, which can be pivoted into a vertical movement path 15a, by means of a sliding or rolling element 97 and a cylinder 63.1.
  • Additional holding means in the form of inflatable cuff grippers 99 are arranged on both sides of a holding beam 101 and cooperate with the pins 34 of the transit beam 95.
  • EP-OS 303 877 (US Pat. Registration 07 / 233,564).
  • the bar 101 can either be fixed in the longitudinal direction of the flyer (FIG. 15, right half) or displaceable by at least half a division 36 (FIG. 15, left half).
  • the longitudinal displacement device can have a toothed rack 103 on the beam 101 and a driven pinion 104 on the holding arm 105. Both empty sleeves 11 and full sleeves 10 can be gripped with the grippers 99.
  • the carrier 21.1 runs empty, first along the path 15a, then along the path 15b, takes the full sleeves 10, the grippers 99 being guided over the sleeves from above, and places them on the clipboard 49. Subsequently, the empty carrier 21.1 the empty sleeves 11 from the transit bar 95, the grippers 99 being guided over the sleeves from below. It should therefore be noted that the dimension of any flange on the underside of the sleeve may have to be reduced.
  • the empty sleeves 11 are again brought into the inclined position via the path 15a and the inclined path 15b and placed on the spindles 13.
  • the full sleeves 10 are then guided from the intermediate storage 49 to the transit bar 95 during a vertical upward movement. Any longitudinal displacements are unnecessary here.
  • FIG. 20 Another mode of operation is shown in FIG. 20. It is carried out analogously to the description of FIG. 18.
  • FIG. 21 with a further mode of operation still requires a little explanation, as follows: The carrier 21.1 moves empty into the inclined position, fetches the full sleeves 10 and transfers them to the transit bar 95. Essentially simultaneously with the downward movement handing over the full sleeves 10, the empty sleeves 11 are received.
  • FIGS. 16 to 21 A comparison has been made in FIGS. 16 to 21 for a clearer understanding. It should be noted that, apart from the horizontal connecting lines which do not represent any movements, a solid line represents the transport of empty sleeves 11 and a solid line with crossbars represents the transport of full sleeves 10. A dashed line means that the carrier 21, 21.1 or the converter 106 (FIG. 16) is moved without sleeves.
