Definitions

  • a yarn wind is supported on the table and moves with the table past a plurality of working positions.
  • First means for ejecting in one of said working positions of one core are disposed in an axial recess of the yarn spool from the upper side of the table, and second means for injecting in another of the working positions of another core from the lower side of said table are arranged.
  • the table has passage openings having a diameter substantially equal with the largest diameter of the cores, and the first means for ejecting and the second means for injecting operate through the passage openings of the table.
  • the present invention relates to an apparatus for the insertion of a core into the axial opening of yarn spools or the like.
  • Yarn spools or the like carry in their axial opening socalledcores, which comprise generally pasteboard tubes or metal tubes of truncated cone shape or radially resilient wire sleeves.
  • the pasteboard tubes which originate from the spooling process, are exchanged to metal tubes consisting of perforated sheet metal or of resilient wire.
  • the metal tube is exchanged again to a pasteboard tube after the dyeing process. If the yarn winding has been spooled directly on a metal tube, it is dyed in this position. After the dyeing process, the metal tube is exchanged again, however, to a pasteboard tube. This is brought about again in order that not too many metal tubes are required, as dye spools are available in storage.
  • this core rests on a moving table and passes in different working positions of this device, of which at least one of the working positions serves the purpose to eject the core disposed in the axial recess of the yarn spool, while at least one additional working position is provided in order to inject the other core.
  • the constructive arrangement of these automatic devices is substantially such that a spindle vertically reciprocating relatively to the moved table and a vertically reciprocating tube, respectively, is provided.
  • An advantageous embodiment comprises furthermore, in accordance with the present invention, an arrangement wherein the core to be injected stands in the injection- :read-y position within a half tube disposed axially below the passage opening of the table.
  • a structure of the device which has a great output and which makes it possible in a simple space saving arrangement independently from the often varying structure of the core to provide a protecting ejection of the present yarn winding and a protecting injection of the new yarn core. Due to the fact that the yarn core is ejected during the ejection from above through the passage opening of the rotary table, it can be prevented with sufiicient safety that even in the case of a corresponding hard structure in the inner range of the yarn winding, a protecting ejection takes place without danger that the yarn positions are pulled along during the ejection movement.
  • the passage opening in the rotary table can be adjusted as to its diameter with suflicient exactness to the largest diameter of the yarn core, so that also the yarn positions disposed closest to the yarn core still have a sufiicient support on the engaging face i of the rotary table. Since the yarn cores disposed in the core projecting beyond one end face brings about a centering position relative to the passage opening of the rotary table by projecting into this passage opening. The core can be moved with appreciable angular speed into the ejection position. The end of the core projecting upwardly at the opposite end face of the yarn spool makes possible a slight fit-like ejection by means of the picking member.
  • the yarn core Since the yarn core has generally the shape of a truncated cone, the core falls easily upon engagement by the picking pusher through the passage opening of the rotary table. Already the bullet-like accelerations, obtained by means of such picking pusher, reduce the danger that the yarn positions are pulled along during such ejection movement. It has been found that the core, which is freely disposed on the rotary table, can be moved further with the same sufficiently large angular speeds of the rotary table, without changing its position, particularly if the rotary table is equipped with corresponding receiving recesses complementary to the member received, which surround the passage of the rotary table. In the injecting position, the new yarn cores are then inserted into the yarn winding from above by means of a holdingdown member.
  • FIGURE 1 is a cross-section of the apparatus, designed in accordance with the present invention.
  • FIG. 2 is a section through the apparatus in an intermediate position of the ejection process along the lines 22 of FIG. 3;
  • FIG. 3 is a top plan view of the apparatus
  • FIG. 4 is a section along the lines 4-4 of FIG. 1;
  • FIG. 5 is a part section through the apparatus in the injection position of the machine.
  • the apparatus comprises a machine frame 1, on which a table 2 is movably mounted.
  • the table 2 is designed as a rotary table. It comprises two rotary table plates 2 and 2" disposed parallel to and spaced apart from each other.
  • the table 2 is equipped with passage openings 3.
  • the latter comprise distancing tubes 4 which simultaneously hold together the plates 2' and 2 of the rotary table.
  • the passage openings 3 correspond as to their diameter to the largest diameter x of the cores 5.
  • Disks 6 are disposed above the passage openings 3, which form with their upper side mounting recesses, which are adjusted to one end face of the yarn cheese 7.
  • the disks 6 have a radial open slot 8.
  • the rotary table 2 is driven stepwise by means of a motor 9 over a drive 10 and clutch 11 including a Maltese cross 12 which engages a cam 13.
  • a picking pusher 15 is provided on a stand 14, the pusher rod 16 of the picking pusher 15 being coupled with a pneumatic piston, which reciprocates in a pneumatic cylinder 17.
  • the stepwise movement of the' rotary table 2 is arranged such that after each step a passage opening 3 is disposed below the picking pusher 15.
  • a groove 18 is provided axially aligned and below the picking pusher 15 in the machine frame 1, in order to catch the cores 5 driven through the pass-age opening 3 and to feed the same to a collecting container.
  • a half tube 19 is disposed immovably at another point below the rotary table 2.
  • the half tube 19 is mounted such that likewise after each stepwise movement of the rotary table 2, a passage opening 3 is exactly above the half tube 19.
  • the ejection position and the injection position I are disposed 120 apart relative to each other, while the passage openings 3 have an angular distance of 60 relative to each other. Each passage opening 3 reaches thus only after each second advancing step of the rotary table 2 the range of the injection position.
  • a lifting head 20 is arranged axially relative to the half tube 19.
  • the lifting head 20 is likewise pneumatically operated, by reciprocating a piston in the pneumatic cylinder 21.
  • the lifting head 20- enters during its upward movement the passage opening 3 of the rotary table 2 disposed thereabove.
  • the lifting head 20 feeds the new core 5 in upright position upwardly into the axial recess of the yarn spool 7' mounted on the rotary table 2.
  • a vertically reciprocating holding-down member 22 engages in the direction of the arrow during the injection process the upper end face 23 of the yarn spool 7.
  • the holding-down member 22 is likewise controlled within the cycle. It slowermost position is always obtained during standstill of the rotary table only.
  • the holdingdown member 22 has an opening 24, which corresponds about to the diameter of the narrower end of the core 5, into which opening 24 this narrower end of the core 5' enters during the injection process.
  • the individual cores are fed in radial direction in the direction of the arrow z (FIG. 5) into the injectionready position and particularly from a magazine 25.
  • the latter rotates continuously.
  • It is equipped with guide sheets 26, which provide that the cores, disposed in standing position on the magazine plate 25, are always fed in outward direction. Thereby, they are fed jamming into a channel 27 disposed tangentially to the magazine plate 25 towards a wall 28.
  • the forwardmost disposed core 5 is brought within the operation of the cycle from a feeding-pusher 29 standing on the lifting head 20, which is in its lowermost position.
  • a light beam 30 is provided (FIG. 3). This light beam 30 causes the picking pusher not to start operation, if during the corresponding step-in, the holding position of the rotary table 2, the light rays of the light beam 30 are not interrupted.
  • a deviating sheet 31 is provided behind the injection position taken in the direction of rotation, which strips the yarn spools 7' equipped with a new core from the rotary table.
  • the entire stepwise control of the rotary table 2, of the picking pusher 15, of the holding-down member 22, of the lifting head 20 and of the pusher 29 is controlled by a switching member 32, which is mounted on the driving axis 33 of the rotary table 2.
  • the light beam 30 controls the entire operation through the switching member 32.
  • the yarn spool containing the core to be ejected, is positioned looking in rotary direction prior to the ejection position on the rotary table 2.
  • the adjusted position can be easily obtained, because generally one end 34 of the core 5 projects beyond the lower end face 35 of the yarn spool 7 and can be guided therefore in the passage opening 3 and in the opening of the carrying plate disposed thereabove, respectively.
  • This yarn spool is then moved during next or second next rotary step of the rotary table 2 below the picking pusher 15. The latter falls down hittingly downwardly.
  • the yarn core 5 is ejected through the passage opening 3 of the rotary table 2 in downward direction.
  • the rotary table 2 moves one step further.
  • the next yarn winding is moved into the ejection position.
  • the first yarn winding moves into the injection position.
  • the pusher 29 has moved a core 5' onto the lifting head 20.
  • the holding-down member 22 moves downwardly.
  • the yarn spool is now clamped between the rotary table 2 and the holding-down member 22.
  • the lifting head 20 moves then upwardly and eject-s a new core 5 into the axial opening of the yarn spool 7'.
  • the lifting head 20 moves upwardly and pushes the new core 5' into the axial opening of the yarn spool 7'.
  • the lefting head 20 moves again downwardly.
  • the holding-down member 22 is again lifted.
  • the rotary table 2 moves now one step forward.
  • the yarn winding 7' equipped with a new core 5' is stripped off by the sheet 31 from the rotary table 2.
  • An apparatus for the ejection and insertion of a core into the axial opening of yarn spools or the like comprising a frame,
  • said table having passage openings having a diameter substantially equal with the largest diameter of said cores
