  • ABSTRACT OF THE DISCLOSURE A method and apparatus for the treatment of rejected delivery bobbins from a textile machine of the type having a plurality of winding locations wherein yarn is delivered along a predetermined path from a delivery bobbin to a wind-up bobbin, the invention being characterized by the features that the winding operation is monitored to determine the existence of certain faults.
  • the delivery bobbin is ejected and, simultaneously with the determination, a control signal is generated having characteristics indicative of the reason for the ejection of a delivery bobbin. The characteristic control signal is then utilized to correctly sort the ejected bobbins with respect to the yarn remainder thereon.
  • the present invention has reference to an improved method of handling or processing ejected delivery bobbins or cops and to an improved apparatus for use in conjunction with an automatic winder for the performance of the aforesaid method.
  • the delivery bobbin sleeves which are ejected or doifed at the winding station are collected, and those sleeves carrying a small yarn remainder are delivered to a cleaning apparatus in order to remove such yarn remainder, whereas the sleeves which still carry a considerable yarn supply are appropriately processed in order to again be introduced to the winder, i.e. one of its winding stations.
  • Another important object of this invention is directed to an improved method for quickly and effectively classifying ejected delivery bobbins as a function of the extent of the yarn package remainder thereon.
  • a further noteworthy object of the present invention relates to an improved method of sorting delivery bobbins ejected from a winder in accordance with the quantity of yarn remaining at each ejected bobbin and in dependency of the operation of yarn sensing or feeler elements.
  • the method of the present invention is characterized by the features that, for each delivery bobbin there is determined the reason for its having been ejected, there is then generated a signal which corresponds to such cause of ejectionof the bobbin, and this signal is then employed for sorting the ejected delivery bobbins.
  • the present invention is also concerned with an improved apparatus for automatic winding machines or winders for carrying out the aforesaid inventive method.
  • Still a further object of this invention relates to an improved apparatus for automatically sorting the ejected bobbins of a winding machine as a function of the amount of remaining yarn package thereon.
  • Another considerable object of this invention pertains to improved apparatus for handling the bobbins ejected at a winder and in dependency of the operation of the yarn feelers thereof.
  • the apparatus of the invention makes use of the fact that at least periodically feelers cooperate with the winding locations of such automatic winders which, on the one hand, monitor the presence of the yarn at a given or predetermined location of the yarn path and, on the other hand, scan or sense the quantity of yarn remaining at the delivery bobbin, whereby such feelers generate signals which control the servicing or tending mechanism.
  • feelers cooperate with the winding locations of such automatic winders which, on the one hand, monitor the presence of the yarn at a given or predetermined location of the yarn path and, on the other hand, scan or sense the quantity of yarn remaining at the delivery bobbin, whereby such feelers generate signals which control the servicing or tending mechanism.
  • the inventive apparatus is generally characterized by the features that, the yarn feelers serve as control elements for a sorting mechanism operatively connected at the winder and receiving the ejected or doffed wind-off bobbins.
  • This ejected delivery bobbin can again be manually reintroduced to the winding machine, so that it must be classified or separated from the other type delivery bobbin sleeves which are to be cleaned.
  • both yarn feelers produce an error signal in that both the yarn at the monitored location of the yarn path is missing and also an insufiicient yarn remainder has been determined to be present at the bobbin sleeve, then this bobbin is likewise ejected or dofied. Due to the response of both yarn feelers, it can be assumed that the bobbin sleeve is completely empty. This bobbin sleeve is therefore only ready to be delivered to a spinning machine, it is therefore to be differently classified from both of the other bobbin sleeve types.
  • the apparatus is preferably provided with three sorting chutes or channels which are either opened or closed in accordance with the control signals produced by the yarn feelers.
  • FIGURE 1 schematically illustrates one of a plurality of winding stations of an automatic cross-winder which carries out, in well-known manner, a travelling or revolving movement relative to an automatic servicing or tending mechanism;
  • FIGURE 2 is a circuit diagram for a first embodiment of inventive apparatus depicted in FIGURE 3;
  • V FIGURE 3 is an exemplary embodiment of sorting mechanism or apparatus for the ejected or doffed delivery bobbins and used in conjunction with the structure depicted in FIGURES 1 and 2; I
  • FIGURE 4 illustrates a circuit diagram for a further embodiment of inventive apparatus depicted in FIGURES 5 to 7.
  • FIGURE 5 illustrates a fragmentary, schematic view of sorting mechanism used in the winder of FIGURE 1 and with the circuit arrangement of FIGURE 4 and depicted in the normal operating position;
  • FIGURE 6 depicts the sorting mechanism or apparatus of FIGURE 5 in a second operating position
  • FIGURE 7 illustrates a third operating or working position of the sorting mechanism depicted in FIGURE 5.
  • the yarn F travels from a delivery bobbin or cop 1 through a known lamella-type combination yarn feeler and balloon breaker device 2, a yarn brake 3, over a stop bracket 4 and a grooved drum 5, to a Wind-up bobbin 6.
  • the remaining conventional yarn guide elements have not been depicted in order to preserve the clarity of the drawing.
  • the yarn feeler and balloon breaker device 2 may be of the type described and claimed in my commonly assigned United States Patent 3,199,806, granted Aug. 10, 1965, and also depicted in my aforementioned co-pending United States application, Ser. No. 360,226.
  • the stop bracket 4 which is pivotable about a pivot shaft 7 possesses an arm 8, the latter acting upon a switch 9.
  • This switch 9 is electrically coupled in the current circuit 10 of a current source 11 and a suitable drive motor 12 driving the grooved drum 5. Furthermore, switch 9 also is connected in the current circuit 13 of a current source 14 and two parallely connected electromagnets 15 and 16.
  • Upon excitation of the electromagnet 15 it actuates the aforementioned yarn feeler device 2, in that its core or armature 17 pivots the double-arm lever 18 in counterclockwise direction about its pivot shaft 19 and thus rocks the feeler fingers 20 provided at a hub 21 of such double-arm lever 18, so that they move into the slots 22 of the lamella-type yarn feeler device 2.
  • the arm 18' of the double-arm lever' 18 acts upon a switch 23 situated in a current circuit 24 of a current source 25 and an electromagnet 26.
  • the electromagnet 16 actuates via its guide 27 and an angle lever 28 a yarn remainder feeler device 29 in that such is guided towards the delivery cop or bobbin 1.
  • one feeler arm 30 bears against the unwound portion or base 1' of the bobbin sleeve 1 and the other feeler arm 31 bears against the yarn package 1".
  • a switch 32 is arranged at the feeler arm 30 and is connected in parallel in the current circuit 24 with the switch 23 of the yarn feeler device 2.
  • a switching or control finger 33 'adjustably arranged at the feeler arm 31 is capable of actuating the switch 32 as soon as both feeler arms 30 and 31 fall below a predeterminedrelative position.
  • the core or armature 34 of the electromagnet 26 is arranged such that in excited state, as shown in phantom line position by reference character 34a, it actuates a release lever of the automatic servicing or tending unit (not shown), thereby triggering a bobbin-exchange operation.
  • This actuation takes plance during and by virtue of the relative movement of the winding station to the tending unit, and has already been considered in detail in my previously mentioned co-pending United States application Ser. No. 360,226.
  • the mode of operation of the depicted winding station or location is as follows: Should rupture of the yarn F occur, then the stop bracket 4 falls forwardly, actuating the switch 9 by means of its arm 8.
  • the latter is equipped with two pairs of contacts, one pair serving as the cut-off contacts for opening the current circuit 10 to thereby stop the bobbin drive motor 12, whereas the other pair acts as cut-in contacts and closes the current circuit 13 and, therefore, excites both electromagnets 15 and 16. Consequently, both yarn-monitoring or feeler elements, namely the yarn feeler device 2 and the yarn remainder feeler device 29 are placed in operation. If one or the other, or both, yarn-monitoring devices respond, then the associated switch 23 or 32 is closed and thus the current circuit 24.
  • Switch 23 is closed by the arm 18 insofar as no yarn is available at the yarn feeler 2; on the other hand, the fingers 20 bear against the yarn F when present and therefore hold back the angle lever 18 from actuating the switch 23.
  • the other switch 32 closes when the yarn package 1" has dropped below a certain package size.
  • a bobbin-exchange operation is necessary because the conventional yarn finder or seizing arm (not shown) is unable to grasp the yarn end of the wind-off or delivery bobbin 1 in that such seeks the yarn directly beneath the yarn feeler device 2, and, in the second case, because the wind-off bobbin 1 is empty or only exhibits an insufiicient yarn remainder, which does not justify knotting and further winding.
  • both of the electric switches corresponding to FIGURE 1, and associated with the yarn-monitoring or feeler elements 2 and 29, are designated by reference characters 23 and 32.
  • both switches 23 and 32 are each equipped with two contracts 40a, 40 and 41a, 41 respectively.
  • a respective contact 40a and 41a of each switch 23 and 32 is connected in parallel with the current circuit 24 of the current source 25 and serves to trigger the bobbin-exchange operation by means of the electromagnet 26, as has been considered in connection with the description of FIGURE 1.
  • the other contacts 40 and 41 are electrically coupled to a respective relay 42 and 43 and to a current source 44.
  • Each of these relays 42 and 43 possesses three contacts, namely two respective closing contacts a, c and d, e, and one respective opening contact b and 1, wherein two respective contacts thereof, as shown, are connected in series with a respective electromagnet 45, 46 and 47 and are electrically coupled with a current source 48.
  • the contacts a and c of the relay 42 and the contacts d and e of the relay 43 are open, on the other hand, the contact b of the relay 42 and the contact f of the relay 43 are closed.
  • the contacts a and d and the magnet 45, the contacts [2 and e and the magnet 46, as well as the contacts c and f and the magnet 47 are each connected in series.
  • FIGURE 2 From an inspection of FIGURE 2 it will be recognized that upon response of the yarn feeler 2 (switch 23) the electromagnet 47 is excited, upon response of the yarn remainder feeler 29 (switch 32) the electromagnet 46 is excited, and upon response of both monitoring elements (switches 23 and 32) the electromagnet 45 is excited.
  • FIGURE 3 there is depicted a bobbin-sorting trough or channel 50 which is arranged at an inclination or downward slope in the direction of the arrow A.
  • Trough or channel 50 is provided with two openings 5011- at its floor 50a which can be closed by associated flaps 51 and 52.

Further, these flaps 51 and 52 are held in their closed position by means of springs 55, against the impact or stops 50 of the channel 50, as shown in the case of the flap 52.
  • a shaft 56 is rotably mounted parallel to the trough or channel 50.
  • the electromagnet 45 disposed between the arm 60 and the extension 59 of the lever 59 protruding past the shaft 56 can work against the action of the spring 58 to rock the shaft 56 in counterclockwise direction.
  • Levers 61 are affixed to the shafts 53 and 54 of the flaps 51 and 52 respectively, which levers are operatively connected by pull rods 62 with the electromagnets 46 and 47.
  • These electromagnets 46 and 47 are on the other hand connected to the arms 63 of the channel 50.
  • a flap could also be associated with the electromagnet 45 in analogous manner to the flaps 51 and 52.
  • the bobbins 1 ejected from the cross-winder slide from the upper left end of the trough or channel 50 downwards until they arrive at an open flap 52 or 51, which together with their extensions 52' and 51 respectively, serve as guide means or plates and allow such to fall into the receptacle or otherwise situated therebeneath.
  • switches 23 and 32 actuated by the yarn-monitoring or supervising elements and which are each provided with two respective contacts 40a, 40 and 41a, 41, of which a respective one 40a and 41a serves to actuate the bobbinexchange magnet 26.
  • the second respective contact 40 and 41 of these switches 23 and 32 leads to two respective relays 42 and 43, each of which possesses two switch-in contacts I), c and d, f, and one switch-out contact a and e respectively.
  • a respective switch-out and switch-in contact a and d and electromagnet 46, as well as the contacts b and e and the electromagnet 47, are connected in series.
  • Both of the cut-in or switch-in contacts c and f serve to bridge their associated impulse contacts 40 and 41 in order to hold the relays 42 and 43.
  • both of the electromagnets 46 and 47 are also under current until the contacts 70 and 71 are opened after a predetermined program and therefore release the relays 42 and 43. Opening of the contacts 70 and 71 can take place by a cam disk 72 arranged at the usual control shaft 73 associated with the tending or servicing unit and which also actuates the remaining elements of the aforesaid tending .unit. Opening of such contacts can, however, also be brought about by a suitable time switch or timer.
  • FIGURE 5 depicts a sorting device or apparatus controlled by the circuit of FIGURE 4.
  • the bobbins ejected or dotfed by the cross-winder are delivered to the upper end of the bobbin receiver or channel 74.
  • This channel 74 widens in the direction of fall of the bobbins 1 and is divided by spaced partititions or intermediate walls 75 and 76 into three compartments or channels 77, 78 and 79.
  • At the upper respective ends of these intermediate walls 75 and 76 there are arranged at shafts 82 and 83 the pivotable guide flaps 80- and 81 respectively.

  • both relays 42 and 43 are energized. Due to their alternate contact positions, both of the electromagnets 46 and 47 are not furnished with current.
  • Both of the flaps 3i and 81 thus remain in their normal or basic position, that is, impact against the outer Walls 74' and 74", as depicted in FIG- URE 5.
  • the bobbins or spools 1 introduced into the channel 74 are therefore guided into the channel 78.
