  • This invention relates to improvements in automatic bobbin winding machines such as exemplified in US. patent application Ser. No. 231,390, filed Oct. 18', 1962, now Patent No. 3,327,736, and US. Patent No. 3,227,384, issued J an. 4, 1966.
  • the foregoing patent and patent application disclose automatic mechanism operable in conjunction with an automatic bobbin winding machine for carrying a plurality of different types of yarn, and means operable to deliver on signal a selected one of the yarns to a bobbin in the winding machine for winding thereon.
  • the signalling means employed in conjunction with the mechanisms of the cited patent and patent application includes electromechanical means interconnecting .the' associated bobbin reserve magazine with the yarn selection system.
  • the bobbin reserve magazines are normally of the variety which are divided into a number of compartments, each compartment being adapted to contain a row of vertically superimposed bobbins, and the bobbins of each compartment usually being wound with a different type of yarn.
  • the signalling means of said patent and application are operative to detect the presence of bobbins at several different levels in each of the compartments of the magazine. In the absence of bobbins at any of the several levels the signalling means operates to control the yarn selection system so that yarn of the particular type required to supply the least filled of the several compartments will be placed on the next bobbin to be wound. Hence, the signalling means will function to maintain a predetermined level or number of bobbins in each of the several compartments.
  • the signalling means of the cited patent and patent application while having a high degree of reliability, is relatively complex in nature. Such complexity presents factors of higher cost of initial manufacture as well as higher cost of maintenance.
  • Another object of the present invention is to provide an automatic winding machine for winding a bobbin with a selected one of the plurality of different yarns and having mechanism which establishes the winding sequence identical to bobbin use on an associated loom.
  • Yet another object of the present invention is to provide mechanism for transmitting a signal received from a bobbin prior to its winding which said mechanism is readily adaptable to existing bobbin winding machines.
  • a further object of the present invention is to provide bobbins having indicia thereon corresponding to a particular type of yarn to be wound on the bobbin.
  • Another object of the present invention is to provide 3,384,314 Patented May 21, 1968 automatic means capable of receiving a signal controlled by indicia on a bobbin to be wound and controlling yarn selection means for presenting a yarn of a given type for winding on said bobbin.
  • the invention accordingly comprises the apparatus possessing the construction, combination of elements and arrangements of parts which are exemplified in the following detailed disclosure, and scope of the application which will be indicated in the claims.
  • the present invention includes, in conjunction with automatic bobbin winding mechanism, yarn carrying means adapted to hold a plurality of different yarn in accessible condition for delivery to a bobbin to be Wound.
  • a sensing mechanism is provided which is operable to communicate with a bobbinas said bobbin is being transferred from a reserve position to a winding position on the winding mechanism.
  • the sensing mechanism reads or senses indicia means formed on the bobbin and, responsive thereto, serves to actuate mechanism for controlling the supply yarn selection system.
  • the yarn carrying mean is actuated so that yarn of the type appropriate to the bobbin to be wound is presented to said bobbin after the bobbin has been donned in its winding position.
  • the indicia on the bobbin are correlated with a predetermined type of yarn to be Wound on said bobbin.
  • bobbins are rewound in exactly the same sequence as they are discharged from the shutttle of an associated loom. This result is achieved because the spent bobbins are recycled to the winding mechanism in the same order that they are ejected from the loom shuttle.
  • FIG. 1 is a top plan view of an automatic bobbin winding mechnaism incorporating the present invention, the components of the invention being shown in the bobbin sensing position, and parts of the machine being broken away to illustrate operative elements therein;

  • a traverse rod 22 extends from within casing 16 in a path parallel to shaft 18 and is enagageable threadedly with yarn guide 20.
  • the traverse rod is operated to move the yarn guide in consequence of which supply yarn is caused to be wound on the rotating bobbin B from the but end to the apical end in the manner of a filling wind. After winding, each bobbin is automatically doffed and a fresh bobbin may be donned in position between chucks 12, 14 for winding. All of these operations are carried out automatically as set forth in the referenced patent and patent application.
  • a cross shaft or cycling cam shaft 24 is positioned within casing 10 to accommodate thereon a plurality of cams, three of which are especially germane to the present invention. These cams are numbered 28, 28 and 30.

  • a yarn delivery arm 54 is provided. This arm is arranged to move in a stroke of predetermined path and length. In the course of said stroke the arm 54 is operable to receive and hold a one of the supply yarns and to deliver this yarn over bobbin B.
  • the particular supply yarn seized by arm 54 is determined by the position of carrier 42. That is to say, the carrier 42 operates to align a one of the supply yarns Y in the path of arm 54. It is the yarn which is so aligned which is delivered to the bobbin for winding.
  • a positioning shaft 56 is provided for operating yarn carrier 42.
  • Said positioning shaft 56 has one of its ends situated within casing 10 and this shaft extends outwardly from the casing through a suitable aperture with its opposite end terminating beyond yarn carrier 42.
  • the inner end of positioning shaft 56 is connected to one end a generally vertical cam follower arm 58.
  • the distal end of said arm 58 is loosely supported on bar 38 for rotation.
  • the mid-portion of arm 58 has a cam roll 60 mounted thereon which is aligned to ride on the periphery of cam 30.
  • the outer section of positioning shaft 56 is joined with yarn carrier 42 through linkage 61 so that as cam shaft 24 is rotated, the carrier 42 is rocked.
  • a spring 62 is connected at its opposing ends to a leg 6'4 fastened to the rear wall of casing 10 and to an appendage 66 fast on shaft 56. Said spring 62 serves to bias positioning shaft 56 leftward (viewing FIG. 3) and acts to hold roll 69 in engagement with cam 30.
  • an upstanding lever 68 is securely affixed to shaft 56 for movement therewith.

  • the mechanism for effecting this transfer includes a pair of quadrant-shaped arms 88, 89 mounted for rotative movement on a shaft 90. The forward ends of arms 88 are notched at 92 to adapt them to engage firmly with the barrel of the bobbin being transferred to winding position.
  • the bobbin is held against notches 92 by a spring biased plate 94 (FIG. I) mounted on a rod 96 which, in turn, is carried by an arm 98 slidingly mounted on shaft but keyed to rotate downwardly in unison with arms 88. Arm 98 is spring biased relative to said shaft 90 such that plate 94 is urged to engage the bobbin.
  • a spring biased plate 94 (FIG. I) mounted on a rod 96 which, in turn, is carried by an arm 98 slidingly mounted on shaft but keyed to rotate downwardly in unison with arms 88. Arm 98 is spring biased relative to said shaft 90 such that plate 94 is urged to engage the bobbin.
  • shaft 90 is rotated through approximately ninety degrees of arc to rock the quadrant arms 88 and thus carry the denuded bobbins B down into winding position.
  • This operation is performed by means of a bevel gear 100 (see FIGS. 1 and 5) which is fast on the inner end of shaft 90 and adjacent a bearing block 102 which rotatably supports the inner end of shaft 90.
  • the gear 100 meshes with the teeth of a quadrant 104 rotatably supported on a stub shaft 106 fast in an arm 108 projecting outwardly from the block 102.
  • the quadrant 104 is formed with an upstanding portion 110, to the outer end of which is connected a helical spring 112 anchored at its opposite end to a hook 114 fastened to the interior wall of casing 10.
  • the spring 112 tends to rock the quadrant 104 in clockwise direction, as viewed in FIG. 5, to cause its teeth to turn the gear 100 for rotating shaft 90.
  • rotation of shaft 90 as just described causes arms 88, 89 to swing in a counterclockwise direction as viewed in FIG. 6.
  • the quadrant 104 For rotating the shaft 90 in the opposite direction to swing the arms 88, 89, and plate 94 upwardly to rest position following delivery of a bobbin for winding, the quadrant 104 is rocked in the opposite direction against the tension of the spring 112 by means of cam 26 engaging a roller 116 journalled on a pin 118 fast in the lower triangular extension of the quadrant.
  • cam 26 is so shaped that rotation of the crossshaft 24 will cause actuation of arms 88 and 89 in the desired sequence.
  • cam 26 is configured to include a lobe 26a which operates the arms downward to carry the bobbin from the magazine 86 to the sensing position, dwell portion 26b which controls arms 88, 89 to momentarily interrupt bobbin movement at an intermediate location substantially mid-way between the magazine 86 and winding position, and a recess 260 which operates the arms to deliver the bobbin to chucks 12, 14.
  • mechanism for identifying the bobbin being transported to thereby determine the kind of yarn which will be wound in the ensuing operation is actuated as will be fully described hereinafter.
  • cam 26 After the bobbin identity mechanism has completed its sensing operation, further rotation of cam 26 causes roller 116 to enter recess 26c and thereby actuates movement of arms 88 and 89 and to deliver bobbin B to winding position. It will, of course, be understood that during the foregoing bobbin transporting operation, shaft 24 and, hence, cam 26 are continuously rotating through one complete revolution.
  • each bobbin As each bobbin is wound it is dropped into appropriate compartment of reserve supply magazine 86 (FIG. 1), the magazine and control means therefor being fully set forth in the prior cited patent. Further, as each bobbin is ejected from a shuttle of loom L it is received in a conventional bobbin stripper to have the residual yarn removed therefrom after which it is transferred by a conveyor C (FIG. 1) to be recycled to magazine 86 in a denuded condition. It will be appreciated that the cycling of the bobbins from the loom to the stripper means, and then via conveyor C to magazine 86 is handled so that the bobbins maintain the same order of entry into magazine 86 as their order of ejection from the loom.
  • bobbins having identifying indicia thereon are employed in conjunction with the Winding apparatus.
  • the bobbins B are generally of standard size and shape consistent with bobbins normally employed with a loom winder.
  • the :bobbins herein are slightly modified at their butt ends 119.

  • the plugs 121 are progressively thicker in the succeeding views from 7b-7d to the point where the thickness of plug 121 of the bobbin of FIGS. 7d is equal to the depth of recess 120 therein.
  • the four slightly differing bobbins B just described relate to the positioning of the four yarn types held yarn carrier 42. It follows that there will be as many differing bobbins, i.e., differing in type of marking indicia, as there are different yarns to be wound. It is also to be understood that in the embodiment herein bobbins with recesses of the same depth will all have the same type of yarn wound thereon.
  • the number of bobbins with different indicia thereon as illustrated herein is arbitrary and not limiting of the invention. In practice, it would be possible to wind a single type of yarn or a number of different yarns on the machine being described, with the number of differing bobbins depending-only upon the number of different positions on the yarn carrier 42 which are to be accommodated. If the number of different positions in the yarn carrier 42 is in excess of four, the differing bobbins corresponding thereto would merely be modified by embedding the appropriate number of different sized inserts into their recesses 120, thereby establishing as many variable recesses in the different bobbins as positions to be accommodated. It should be noted that normally each position on the yarn carrier will accommodate a different type of yarn.
  • the bobbins just described are cooperable with sensing mechanism of the winding machine for controlling the supply yarn to be wound.
  • the sensing operation takes place as a denuded bobbin is transferred from magazine 86 to winding position. In the course of this movement the bobbin is halted for a brief moment, in the order of one to two seconds, while sensing of the indieca on the bobbin is achieved.

When the carrier reaches a full rightward position it is released for leftward rocking movement about pivot stud 44 under the bias of spring 62. It will be understood that the extreme rightward position of yarn carrier 42 is at least a distance sufficient to align the yarn held in the extreme lefthand guide 50a and companion clamp-shear unit 52a with the operable path of yarn delivery arm 54.
  • pawl member 192 is to achieve arresting of yarn carrier 42 in a position so that the desired yarn will be placed on the denuded bobbin next to be wound.
  • shaft 144 is rocked to a degree controlled by the limit of movement of plunger 122, pawl member 192 is coincidentally elevated or lowered.
  • each step 184ad is so related to the indicia on bobbins B that the type of yarn correlated to a specific indicum, i.e., a specific depth of bore in the butt of bobbin B, will be wound on that bobbin.
  • the spring 204 (FIGS. 4 and 11) is provided to allow for lost motion as shaft 144 is rocked in its initial stage.
  • a shaft 144 is rocked through its first few degrees
  • lever 202 which is fast on shaft 144 is also rocked.
  • the motion is dissipated via spring 204.
  • ratchet member 180 moves away from pawl member 192 and frees said pawl member lever 200 is urged clockwise in conjunction with the movement of shaft 144. This latter motion is transmitted through spring 204.
  • the invention calls for a sequence for winding new bobbins which is in the same order to that in which spent bobbins are doifed from the loom.
  • the invention therefore, results in a much less complicated, highly elfective mechanism for assuring delivery of wound bobbins to the loom consistent with their rate of use by the loom.
  • a bobbin for use with a winding machine having yarn delivery means operable to deliver on signal one of a plurality of yarns to the bobbin for winding thereon, and discriminating means operable to sense a signal for controlling said yarn delivery means; said bobbin comprising a portion for receiving yarn for winding thereon, and
  • criminating means for providing a signal thereto indicating the one of the plurality of yarns to be wound on said portion.
  • a bobbin as set forth in claim 1 including a base portion connected to said portion for receiving yarn, the indicator means being situated on said base portion.
  • a bobbin as set forth in claim 9 including stop means positioned in said passage to define the depth of said passage.
  • a bobbin comprising, a base portion, an elongated apical portion connected to a first end of said base portion, said apical porton being adapted to have yarn wound thereon, said base portion having a second end remote from said first end, at least a part of said second end defining indicator means for cooperation with an indication detecting element operable to transmit a signal, said indicating means being spaced from said apical portion.
  • a bobbin as set forth in claim 13 including stop means positioned in said passage to define the depth of said passage.
