A TTORNEV SNAGGING DEVICE "Tillman T Bunch, near Ashland, assignor to Western Electric company, Incorporated, New York, N.Y., a corporation or New York Filed May s, 1958, Ser; 133,903 claims. elm-1s The present invention relatsto improved snagging devices, and more partieularly, although not exclusively, to

improved snagging devices for securing a portion ofa strand or filamentary material to one ormore rotatable take-up reels of take-up apparatus which continues to operate uninterruptedly as the distribution of the strand or filamentary material is transferred from one take up reel to a succeeding take-up reel.

In general, insulated electrical conductors are manufactuned by means of a substantially continuous process in which an elongated conductive core or conductor is advanced continuously from 'a supply thereof to and through a series 'of manufacturing apparatus or processes, sueh as continuous extrusion apparatus, to produce the finished insulated conductor. I

Since the stoppage of the extrusion apparatus lessens production, may cause damage to the conductor and causes waste by producing oversized, undersized, o'r nonuniform coverings of insulating material, it is desirable to operate the extrusion apparatus continuously so that interruption of the advancement of the core through the extrusion apparatus does not occur. In order that the extrusion operation may continue without interruption of disturbance, it is common practice to employ take-up apparatus having two or more rotatable take-up reels onto which predetermined lengths of finished insulated conductors are wound successively. In this practice, when a predetermined length of insulated conductor has been wound upon one take-up reel, the insulated conductor is transferred to an empty take-up reel without interrupting the advancement of the insulated conductor emerging from the extrusion apparatus.

In take-up apparatus of this type, means are connected operatively to adjacent sides of each of the takemp reels for gripping portions of the insulated conductor extending between the reels when the distribution of the insulated conductor is transferred from one reel to another. The trailing end of the insulated conductor is secured to the reel filled with the desired amount, and the leading end of the insulated conductor to be reeled on the empty reel is secured thereto. The portion of the insulated conductor extending between the reels is cut by a conventional knife positioned across the path formed by the extending portion of the insulated conductor as the reels continue to :rotate during the transfer of the distribution of the in asulated conductor.

As a result of the increasingly high speeds of opera- .tion of present day manufacturing apparatus, some difliculties have been encountered in attempting to effect successful cutovers or transfers while utilizing prior known type of snagging devices. It is desirable to have improved snagging devices which will assure effective transfers of the distribution or effective cutover operations at high speeds so that when the insulated conductor is moved in contact with the snagging devices during a transfer of the insulated conductor from the full take-up reel to the empty take-up reel, the first snagging device associated with each of the'i'ee'ls to arrive at the position of the in- 2 'sulated conductor will catch a portion of the insulated conductorand they will cooperate with each strawberry the portion 'of the insulated conductor extending therebetween against the cutting knife.

It is desirable to have snagging devices which will insure that when the strand is severed by the knife thenew leading end thereof will remain attached to one d'f'the snagging devices associated with the empty reel and will start to wind on the winding drum of the einpty reel so that reeling of the insulated conductor commences on the winding drum of the empty take-up reel witheut interruption. I L

An object of the present invention is the improvement of snagging devices utilized on take-up "or strand reeling apparatus. p p

A funhe'r object of the present invention is to provide a snagging device for take-up apparatus whereby the takeup apparatus can be operated with greater speed and better eiliciency. v

A still further object of the present inventidn is to provide a snagging device wherein the spacing of the elements betwee which the strand is caught is greater than the outer dimension of strand so that the strand is secured therein but not pinched thereby.

(Ether and more specific objects of the invention include the improvements in construction and cooperative relationship of component parts which go into making up an improved snagging device. V

In attaining these and other objects, take-up apparatus embodying certain features of the present invention may comprise a plurality of rotatably driven take-up reels, a strand distributing means mounted for movement transversely or the winding s rface or the take-up reels, and means for indexing the strand distributing means front an operating station wherein the strand is distributed 611 one of the take-up reels to another operating station wherein the strand is distiibuted similarly upon a succeeding takeup reel. A rotatable snaggin hoop may be connected operatively to each of the reels and have a plurality of spirally shaped snagging fingers encompassing portions of the hoop. The snagging fingers each have a free, end projecting outwardly of the hoop and in the direction 6f rotation of the take-up reel.

Each snagging finger cooperates with the adjacent portion of the associated hoop to form a' strand receiving, tortuous path and thus a snagging device. A portion of the strand, which is caused to contact the outer periphery of the snagging hoops during a cutover operation, is caught in one of the snagging devices associated with each hoop. Thestran'd will ride on the snagging hoops and be struck by the snagging fingers and forced inwardly of the tortuous paths, as a result of the rotation of the snagging hoops, for wrapping the strand around the snagging fingers and portions of the hoops to secure portions of the strand adjacent to each reel when the distribution of the strand is indexed from one reel to a succeeding reel.

Other objects and features of the inventibn will b more readily understood from the following detailed description when read in conjunction with the accompanyin'g drawings, in which:

Fig. 1 is a fragmentary, top plan View of a'poit'io'ri of a take-up apparatus embodying the invention;

Fig. 2 is a fragmentary, enlarged, sectional, side elevational view of a portion of the take-up apparatus as illustrated in Fig. 1 taken along line 22 thereof;

Fig. 3 is a fragmentary, enlarged view of the snagging device of Fig. 2, and I Fig. 4 is a fragmentary, enlarged, broken, sectional view of a portion of the take-up apparatus illustrated in Fig. 2 taken along the bent'li'ne l-4 thereof.

Referring now to the drawings, and more particularly to Figs. 1 and 2 thereof,- was is showda' takeflange-like reel heads 16-16 secured fixedly at opposite ends of the winding drum 15, but unlike reels could.

be used.

The reels 13 and 14 are urged toward the support member 12 by fluid piston-

cylinder assemblies

17 and 18 which are secured to rigid support members 19-19 of an inverted U-shaped frame 20 on opposite sides thereof, through the pins or live centers 21 and 22 of tail stocks which help to support the reels 13 and 14, respectively. The reels 13 and 14, which are acted upon by the

pistoncylinder assemblies

17 and 18, are urged against snagging wheels, designated generally by the numerals 23 and 24, respectively, secured rotatably to the rigid support member 12.

The reels 13 and 14 which are acted upon by the piston-

cylinder assemblies

17 and 18 are urged against annular friction members 26 and 27 (Fig. 4) secured rigidly to hubs, designated generally by the

numerals

28 and 29, forming parts of the snagging wheels 23 and 24, respectively. The reels 13 and 14 are urged also against horizontally projecting portions 31-31 of sealloped annular discs, designated generally by the numerals 32 and 33, secured to the outer periphery of the

hubs

28 and 29, respectively.

The scallops of the annular discs 32 and 33 form a plurality of radially projecting spokes 34-34 of the snagging wheels 23 and 24. Each of the spokes 34-34 has formed integral therewith an arcuately grooved clamping member 36 adjacent to the outer extremity thereof. Each of the clamping members 36-36 cooperates with a clamping member 37 to form a clamp, designated generally by the numeral 38. The clamps 38-38 cooperate to

clamp hoops

39 and 41 to the outer periphery of the annular discs 32 and 33, respectively. The

hoops

39 and 41 form portions of the snagging wheels 23 and 24, respectively.

The outer surface 42 of each of the clamping members 37-37 is sloped to face in the direction of rotation of the associated take-up reel 13 or 14 and is positioned diagonally with respect to the associated

hoop

39 or 41 to prevent any corners thereof from striking the strand 11. The

hoops

39 and 41 are placed in arcuate shaped slots 43-43 near the outer surface and adjacent to the outer extremities of the clamping members 37-37. The outer extremities of the clamping members 37-37 project beyond the associated

hoops

39 and 41 and form lips 44-44 which curve over the

hoops

39 and 41 in a direction toward the companion snagging wheels 23 or 24.

Each of the clamping members 37-37 is secured to one of the clamping members 36-36 on the outer extremity of one of the associated spokes 34-34, with a piece of rubber-like material 46 therebetwcen, by a bolt 47 extending through apertures in the

clamping members

36 and 37 and the associated spoke 34 to clamp the associated

hoop

39 or 41 in place thereon.

Each of the clamping members 37-37 has a hole 48 bored in one extremity thereof. A substantially spirally shaped hollowed-out snagging finger, designated generally by the numeral 49, is positioned into the hole 48 in the clamping member 37 and is brazed therein. Each of the snagging fingers 49-49 partially encompasses an adjacent portion of the associated

hook

39 or 41 in front of the associated spoke 34. The snagging fingers 49-49 each have a free end 51 which points in the direction of 4 rotation of the associated take-up reel 13 or 14 and project outwardly of the associated

hoop

39 or 41.

Each of the snagging fingers 49-49 and the adjacent portion of the

hoop

39 or 41 encompassed thereby cooperate to form a snagging device, designated generally by the numeral 52, and a strand-receiving tortuous path 53. A portion of the strand 11 is directed and caught in the path 53 when the strand 11 is moved in contact with the

hoop

39 or 41 and struck by the projecting free end 51 of the snagging finger 49 during the transfer of the distribution of the strand 11 from one reel to the other during the cutover operation. The portion of the strand 11 caught by the snagging device 52 is wrapped in the form of a bight on the snagging finger 49 and the portion of the

hoop

39 or 41 encompassed thereby.

The reels 13 and 14 are positioned adjacent to the associated snagging wheels 23 and 24, respectively, for rotation concentrically therewith by means of springbiased centers 54 and 56 of head stocks and the

annular friction members

26 and 27 secured to the

hubs

28 and 29, respectively. The supporting centers 54 and 56 of the head stocks are utilized to cooperate with the centers 21 and 22 of the tail stocks to support the opposing ends of the reels 13 and 14, respectively. The respective

annular friction members

26 and 27 which, along with the projections 31-31, help to support the reels 13 and 14, engage the flange-like heads 16-16 of the reels 13 :and 14 and are used for transmitting torque to the reels 13 and 14 from the

hubs

28 and 29, respectively.

The reel supporting centers 54 and 56 are mounted slidably in the

hubs

28 and 29 and on studs 57-57. The studs 57-57 are secured to the

hubs

28 and 29 to prevent relative rotational movement between the centers 54 and 56 and the

hubs

28 and 29, respectively. The

hubs

28 and 29 are mounted rotatably by triplex, angular-contact ball bearings 58-58 in a housing 59 mounted in and secured to the support 12.

The

hubs

28 and 29 are secured rigidly to pulleys 61 and 62, respectively, for rotation therewith. The pulley 61 is connected by means of

endless belts

63 and 64 to a magnetic clutch 66 which is driven rotatably by an electric drive motor, designated generally by the numeral 67, through an output shaft 68, an endless belt 69, and a shaft 71. Similarly, the pulley 62 is connected by means of

endless belts

72 and 73 to a magnetic clutch 74 driven by the electric drive motor 67 through the output shaft 68, the endless belt 69 and the shaft 71.

Magnetic brakes

76 and 77 are connected operatively to each of the drive means associated with the right reel 13 and the left reel 14, respectively. The

brakes

76 and 77 are utilized to stop the motion of a full reel of strand 11 and to create a reserve length in the strand 11 which will permit the cutover from one reel to the other reel to take place without placing excessive stresses in the strand 11.

The strand 11, which may be, for example, an insulated conductor delivered at a substantially constant rate from a continuous extrusion apparatus (not shown) by a conventional strand-advancing capstan (not shown) and through a conventional strand accumulator (not shown). The strand passes to and partially around a rotatable guide sheave 78 and between a pair of spaced, parallel guide fingers 79-79 which are secured to a conventional distributing carriage, designated generally by the numeral 81. The sheave 78 and the guide fingers 79-79 are moved transversely of either of the take-up reels 13 and 14 by the distributing carriage 81 to distribute the processed strand 11 evenly across the winding surface thereof and to guide the strand 11 as the distributor carriage 81 is indexed from one take-up reel to the other during a cutover operation.

The distributor carriage 81 may be driven by any of many well-known means and is mounted slidably, by a bearing 82, on a horizontally extending traverse rod 83 for transverse movement therealong. The traverse rod 83 is supported fixedly to the inverted U-shaped frame awnin s 20" adjacent to the op osing" ends" thereof by' upright members 84-84. I 7

When one of the reels 1'3and' 14 is' 'rotated by themotor 67 to take up the processed strand 11, the dis'trib' utor carriage 81 is moved: transversely of the'winding sur; face of the reel 130i" MandparaIIeI to the rotating axis thereof 'so as 'to rn ove the distributor'whili, intui'ii, directs the processed strand 11 ev'e njlyfbacli and forth -alongtli' winding surface of -the reel lgr orfl f eaten/men the" strandll is beingtal ieh up. The-adjustment of the speed and length or"travelor nrcarnagesr with respect to the rotational sp eedand length 9fthdtalie upreelmay be achieved by anyofrrianywelhknowii means. 7

Suitable'elect'rical and fluid caatiermeans net strewn are provided for stopping, starfifig ahd 'controlling the' take-up apparatus including the driventotorm, the

magnetic clutches

66 and 74, therria'gneticbrake's76 ar1d '77, and the distributing'nieans-fll. The control niaiisiare disclosed inde'tail in a copending application SerialNo'. 656,956, filed on May 3, 1957, in thena'me of B. C. Ellis, Jr., as are many ofthe otherf eatures"ofthetake-up ap paratus.

As the strand 11 is caught underthe e'n'd 51 of one of the snagging fingers 4949 during the cutover operation and is forced inwardly of the tortuous path- 53, it will ride over and partially around the snagging

hoop

39 or 41 and under and partially around the snagging finger 4-9 and will be bent in a' substantially S-shaped configuration. The strand 11' will be caught'in' the tortuous path 53 and held'therein by'being knotted or hitched tothe snagging finger 49 and" adjacent" portion ofthe snagging hoop 39 or 41'to secure the's't'rand'll m the snagging wheel 23 or 24 and, in turn, to the take-up reel 1301" 14 associated therewith.

In this way, each of the snagging fingers'49 49 coi operates with the associated snagging

hoop

39 or 41 to formthe tortuous path 53 into one of which the strand 11 is directed, caught and held'during and after the strand 11 is cut by a conventional knife 86, secured to the support member 12 and positioned between the snagging wheels 23 and 24 and thus the take-up reels 13and 14, as a result of the'rotation of the wheels .13 and 14 during the cutover operation.

As a result of the high speed of rotation of the full reel 13 or'14 with respect to the velocity of the distributor carriage 81 and as a result of the spacing of thejsnagging' fingers 4949 on the snagging wheel 23 or-24, the strand 11 will be caught by the snagging device 52 on the full reel in advance of the relative peripherial position ofthe snagging device-512 which catches'thestrand 11 and attaches it to the snagging wheel 23 or 24 associated with the empty reel. This will result in the strand 11 extending between the wheels 23 and 24 being disposed at an angle with respect to the axis of rotation of the reels 1.3 and 14. The exact degree of the angle will vary depending on the particular circumstances involved during any one cutover.

Operation Assuming that the right reel 13 is being filled with the insulated strand'll beingsupplied from the extrusion apparatus (not shown), the distributor 81 will direct the strand 11' onto the right reel 13,- until a certain predetermined length of the strand 11 is wound thereon as determined by an automatic counter system (not shown) or by conventional manually operated controls. Prior to the cutover being commenced by the counter system, the control system causes the clutch 74 associated with the left or empty reel 14 to be actuated at a predetermined time thereby driving the empty'reel 14 and the partially filled reel 13 at desired predetermined speeds.

When the right take-up reel 13 onto which the processed strand 11 ;is being reeled has become filled com} pletely orfilled with the desired amount of strand 11, an automatic cutover takes place to cause the distributor s1" is inde r the" distribiitidfi' of' the" in'sii neia'the r1111 ree1'13 ta the'einptyfrel v 11" is moved into con'tact'with a snaggingdevice the periphery of the snagging heep 39, and the'n moved into' contact with" a" snagging device 52 on "theperiphery' of the snagging 1160541.

The portion of thestrand 11 extending frbm thdfull'take up"reel will extendout'wardly"in coritaet with thesideof the snagging 1166539 adj scent tdthf full reel" 13; around the outer surface of the hoop' 39, incontact'withthe side of the" snagging finge'ruw" adjacent to the hoop 39, partially around thsriaggirig' finger 49*a1id' to thesnagging finger 49 associated with"theeinpty'take upreel 14. The po'rtio'n of thes't'rfind 11 will"theri extend partially around the"si1agging finger 49; outwardly" to the adjacent sur faceof thesri'agging hoop 41 associated therewith, around. the outer" surface of thesnagg'ing hoop 41," inwardly to" and around the winding drurri 15of theempty take-up reel 14.' I v V The portion of the snagging hoop'39 ando'ne of the snagging fingers49 -49fori-ning oneof the'snagging devices 52-52 asso cia'ted with etake-up reel 13 co operate to tie or hitch thepdrtion of the trailing end of the strand ll wound 'onthe "reel 13 to "the snagging'lwhee'l 23 and] thus'to 'thetake' upre'el' 13f Theportion of the snagging hoop 4'1 andjthesna'ggihgfinger" 49"for'tning the snagging device" 52 associated with thetake-up 'reel' 14 cooperate to tie or hitch the portion'o'f the'le'a'ding end of the strand 11 to be wound'ojn the'take-up reel 14 to the snagging wheel 24' and thus to the takeup reel 14. t o

The strand "11 extending between the' snagging devices" 5Z52 associated with the full reel 13and the empty reel 14 is severed by'the knife 86 as the'reels 13 and 14 carry the portion of'th'e strand 11 extending therebe tween past the cutting edge of] the knife'86. The full reel 13wi1l then bestopped by the magnetic brake/76 associated therewith. The drag'andcentrifugal force of thefree end of the portion of the strand'll connected to the empty reel' 14, created by thecutting of the ex tended portion ofthe' strandll', tend to pull the asso-' ciated hitchor knot tighter and insure that it does not come loose from the'snaggerdeViCeSZ. V

7 Now that" a cutover operation is completed and the leading end of the strandll as be wound on the takeup reel 14 is connected'to' the snagging device 52'associated with the snagging wheel 24, the reeling operation on the left take-up reel 14 proceeds in a normal manner.- The trailing end of the strand 11 wound on the full, right take-up reel 13, which was stopped by the brake 76, is removed manually from the associated snagging device 52. The full reel 13 is thenremoved fron'rthe reel supports 21 and 54 and replacedby an empty take up reel 13. I

The strand reeling or take-up apparatus is now ot'ierating so that the left take-up reel 14 is in the process of being filled. As the strand lladvances continuously, the distributor 31 is reciprocated to distribute the convolutions of strand '11 in uniform layers upon' the winding drum 15 or winding surface of the left take-up reel 14.

Prior to the time the left take up reel 14 has becoine full, or a desired predetermined amount of strand 11 has been reeled thereon, the nia'gnetic'clutch 66 is energized to rotate the empty right take-up reel 13 and the takeup apparatus is again in readiness for a cutover operation to take place. When'ea'ch of the" take-up reels 13 and 14 are running at predeterminedsp eeds and when the left take-up reel 14 has become'filled; completely orlfilled with the'desired amount of strand 11, an automatic"cut-' over operation takes place. v g I} I As the strand 11 is transferred from the full lefttake up reel 14 to the empty right take-up reel 13, one of the snagging devices 5252 on each of the rotating snagging wheels 23 and 24 catch a portion of the strand 11 as described above with regard to the cutover from reel 13 to reel 14. The snagging devices 5252 cooperate to carry the portion of the strand 11, extending therebetween, against the cutting edge of the knife 86, whereby the strand 11 is severed and the new leading end thereof remains attached to the snagging wheel 23 and is wound on the winding drum 15 of the empty right take-up reel 13. Thus, the reeling of the strand 11 commences on the winding drum 15 of the empty take-up reel 13 without interruption, and the full take-up reel 14 is stopped by the magnetic brake 77 associated therewith.

Now that the cutover operation is completed, the reeling operation on the right take-up reel 13 proceeds in the normal manner described previously. The trailing end of the strand 11 wound on the filled left take-up reel 14, which was stopped by the brake 77 associated therewith at the time of cutover, is removed from the associated snagging device 52. The full reel 14 is then removed from the reel supporting centers 22 and 56 and is replaced by an empty reel 14 in preparation for a subsequent cutover operation.

The various steps of the procedure are then repeated to take up strand on succeeding reels.
