Definitions

  • a switching arrangement is arranged in the spooling machine which is actuated in dependence upon severance of a yarn in the yarn cleaner and deactuated upon upward movement of the yarn feeler.
  • the switching arrangement includes a switch which is mounted outside the yarn cleaner and is magnetically actuated by the yarn cleaner upon severance of a yarn to actuate the yarn brake.
  • This invention relates to an apparatus for switching auxiliary Work performers into operation with textile machinery. More particularly, this invention relates to an apparatus for switching auxiliary work performers into operation with textile spooling machines.
  • auxiliary work performers for example, motor-driven spool spindles, counting devices, indicating devices or other apparatus can also be switched into the spooling operation.
  • the electronic yarn cleaners have not been arranged to perform any other switching operations connected indirectly with the cleaning of the yarns. Further, these electronic yarn cleaners have lacked both the ability to supply electrical magnitudes of different kinds and the frequently needed ability to deliver great power.
  • the present invention avoids these above drawbacks in providing a switching apparatus for actuating auxiliary work-performers on spooling machines and other processing machines of the textile industry dependent on the operation of the electronic yarn-cleaners.
  • the switching apparatus has at least one magnetically influenced reed switch relay disposed in the zone of the stray field of the electronic yarn-cleaner for actuation by the stray field with contacts that switch in and switch out auxiliary workperformers.
  • auxiliary workperformers In operation, the current circuits to these auxiliary workperformers become interrupted when the yarn cleaner produces acutting pulse.
  • This pulse serves to energize an electro-magnet to create a stray field which acts on the magnetically influenced reed switch relay to separate its contacts.
  • the contact of the magnetically influenced reed switch relay is held closed by a permanent magnet and an auxiliary field is used to create a lag between the attracting and falling-01f field strengths to lengthen the contactopening time.
  • the special advantage of the apparatus in accordance with the invention is that there is complete galvanic separation of the yarn-cleaner and the switching circuits for the auxiliary work-performers.
  • the apparatus can consequently be installed on existing yarn-cleaners.
  • FIG. 1 diagrammatically shows the principle of the circuit arrangement of a magnetically influenced reed switch relay
  • FIGS. 2 to 5 each show a diagram of a pulse as a function of time
  • FIG. 6 diagrammatically shows the sequential arrangement of a plurality of reed switch relays for the purpose of counting the total number of pulses
  • FIG. 7 diagrammatically shows an arrangement for indicating the non-operative coil locations
  • FIG. 8 diagrammatically shows an arrangement for actuating an additional cutting station outside the yarncleaner
  • FIG. 9 diagrammatically shows an arrangement for stopping the spool spindle upon operation of the yarncleaner.
  • FIG. 10 shows a modified apparatus of the invention.
  • a yarn 1 is pulled off a spool 9 and is spooled on a cross-spool 2.
  • the yarn 1 passes through a yarn-brake 3 driven by a motor 4, an electronic yarn-cleaner 5 having a cutting device 6 actuated by an electro-magnet 7, and a yarn-feeler 13 that is held in a first position by the yarn against pivoting into a second position as shown by the dotted lines.
  • a switch 14 is operatively connected to the yarn-feeler for actuation thereby.
  • the electric circuit of the motor 4 contains a magnetically influenced reed switch relay 10, which is subjected to the influence of at least two magnetic fields.
  • the characteristics of this magnetically influenceable reed switch relay are such that contact is made as an operative contact; that an external magnetic field B is needed to close the contact; and that the field B, can be weakened by a weaker magnetic field B which can, for example,
  • a permanent magnet 11 which produces the [Field strength B needed to close the contact, acts on the treed switch relay 10. Because the stray field B of the cutting magnet 7 is too weak to counteract completely the ipermanent field B of the permanent magnet 11, and because it acts only very briefly, an auxiliary field B is applied in addition by means of an auxiliary coil 12. The strength of the field B is such that it weakens the permanent field B but not sufiiciently for the contact of the magnetically influenced reed switch relay 10 to be opened.
  • a current pulse is produced by the electronic circuit 8 to cause the cutting device 6 to cut the yarn in two thereby creating the stray field B
  • the yarnffeeler 13 pivots upwardly to open the switch 14 of the circuit of the auxiliary coil 12 causing the auxiliary coil to become currentless. Because of this, the field B of the permanent magnet 11 becomes fully effective, and the contact of the magnetically influenced reed switch relay 10 closes again, causing the yarnbrake 3 to rotate.
  • FIGS. 2 to explain in diagrammatic form the chronological correlation of the various switch positions, and explain the magnetic fields acting on the magnetically influenced reed switch relay.
  • FIG. 2 shows the time the switch 14 is switched on, and thus it also shows the duration of the action of the auxiliary field B At the instant t the switch 14 becomes closed, and the auxiliary field B becomes formed.
  • FIG. 3 shows the duration of the stray field B of the electro-magnet 7. This field lasts for the interval of time from to t
  • FIG. 4 shows the resultant magnetic field strength in the region of the magnetically influenced reed switch relay 10.
  • the field strength B of the permanent magnet 11 acts in full strength until the instant 23 when the auxiliary field B becomes built up. The contact is therefore closed, and it also remains closed beyond the instant t At the instant of the cutting pulse the stray field B acts to supplement the auxiliary field B so that the contact opens.
  • FIG. 5 shows the switching periods of the magnetically influenced reed switch relay 10. It is in its ON position until the instant t in its OFF position from t to 1 and in its ON position again beyond t After the yarn ends are knotted together, the yarn-feeler 13 pivots downwardly, thus closing the switch 14 (instant t so that the total field acting on the magnetically influenced reed switch relay becomes decreased again to the vaule B B while awaiting a new cutting pulse.
  • a magnetically influenced reed switch relay 10 presupposes that the case or shell of the yarn-clcaner is made of magnetically non-conducting material, that is, of non-shielding material.
  • This has the valuable advantage that no galvanic connection at all exists between the yarncleaning equipment and the supply for the auxiliary operation, so that this supply can consequently be effected independently of the type of yarn-cleaner used.
  • the magnitude of the auxiliary performance need not be taken into consideration so that any desired counting or indicating means can be used, for example, to count the number of cutting pulses occurring, or to indicate the location of a yarn break.
  • FIG. 6 shows a number of yarn-cleaners 5, 5', 5", with their associated magnetically influenced reed switch relays 1t), 1t), 11)", in whose circuits a counter 15 is set to add a counting pulse for each actuation of one of the yarncleaners.
  • FIG. 7 shows indicatim devices, lamps 16, for example, associated with each yarn-cleaner 5 which light up upon operation of a yarn-cleaner.
  • the extinguishment of the lamps 16 can be done by briefly removing the permanent magnet a distance from the magnetically influenced reed switch relay 1% so that its field is no longer effective. This also opens the reed switch relays.
  • a second cutting station along the path of the yarn, is actuated through the intermediary of a reed switch relay 11?.
  • the reed switch relay actuates a relay 20 which energizes the cutting apparatus 19 upon opening of the reed switch relay, without the cutting apparatus being directly connected with the yarn-cleaner 5.
  • FIG. 9 shows still another arrangement with which the spool spindle 2 is stopped in response to the occurrence of a cutting pulse in the yarn-cleaner 5, for example, through the switching off of the spool motor 22 by a protector 23.
  • the auxiliary field B can also be created through an additional permanent magnet 17.
  • the spooling machine contains a feeler lever 18, which swings with a circular or similar motion past and close to the yarn-cleaner 5 (see FIG. 10) upon cutting of a yarn.
  • a permanent magnet 17 is fastened on this feeler-lever 18 in such a way that its field, in going past the yarn-cleaner 5 or in going close to the reed switch relay 1% in its immediate vicinity, acts counter to the field B of the per nanent magnet 11 to decrease B to the value needed to actuate the reed switch relay 10 for as long as the feeler-lever 1% is situated in the region of the protective-gas contact.
  • the feelerlever 18 out of the region of the reed switch relay 10 Upon removal of the feelerlever 18 out of the region of the reed switch relay 10, then only the full field strength of the permanent magnet 11 acts on the protective-gas contact and holds it closed.
  • a switching arrangement for switching auxiliary work performers into the circuit of said spooling machine upon severance of a yarn
  • said switching arrangement including at least one magnetically influenced reed switch relay positioned outside of said electronic yarn cleaner for disposition in said stray magnetic field, a permanent magnet positioned outside of said electronic yarn cleaner imposing a permanent magnetic field of greater strength than said stray magnetic field on said reed switch relay in opposition to said stray magnetic field, and magnetic field means positioned outside of said electronic yarn cleaner for alternatively imposing an auxiliary magnetic field of less strength than said permanent magnetic field on said reed switch relay in opposition to said permanent magnetic field, said magnetic field means being operatively connected to said yarn feeler for actuation thereby upon detection of a decrease in yarn tautness whereby said relay is opened upon imposition of said magnetic field and said stray field thereon and maintained in open position after decay of said stray magnetic field and is closed upon subsequent decay of said auxiliary magnetic field and maintained in closed position after reimposition of said auxiliary magnetic field.
  • said magnetic field means includes an electric circuit, an auxiliary coil in said electric circuit for creating said auxiliary magnetic field, and a switch interposed in said circuit for opening and closing said circuit, said switch being connected to said yarn feeler for actuation of said switch in response to the tautness of the yarn detected thereby, said switch being activated after severance of the yarn.
