20 Claims.
This invention relates to takeup apparatus, and more particularly to apparatus for continuously winding strands, such as, for example, insulated conductors.
In strand forming and processing operations,
' like must be substituted for the filled takeup apparatus or a switch from one reel to another is inade, it usually has been necessary to shut down the processing apparatus during such a substitution or switching. Such interruptions of the process increase the cost of production of the strand, and, in the case of extrusion and vulcanization of insulated coverings upon conductors, the portions of the coverings remaining in the vulcanizing apparatus during the interruptions are overcured so that the corresponding portions of the insulated conductors must be scrapped. Some continuously operable takeup apparatus have been proposed in the past, but this apparatus has been dangerous and generally unsatisfactory.
An object of the invention is to provide new and improved takeup apparatus.
A further object of the invention is to provide new and improved apparatus for continuously winding thereon strands, such as, for example, insulated conductors.
Another object of the invention is to provide new improved strand takeup apparatus for substantially automatically switching a strand from one takeup reel to another without interrupting the winding process.
A takeup apparatus illustrating certain features of the invention may include a coiling elehent, a second coiling element, means for retating the coiling elements, means for guiding a strand along a predetermined path near to and past the first-mentioned coiling element to the second-mentioned coiling element, a snagger revolved with the first-mentioned coiling element movable from a position at the end of and not extending over the first-mentioned coiling element to a position extending over that coiling element, means for holding the snagger in a position not extending over the first-rnentioned reeling element. and means selectively operable for pu hing the snagger over the first-mentioned reeling element at a predetermined point in the revolu on of the snagger, whereby the snagger catches the portion of the strand guided past the first-mentioned coiling element.

Fig. 3 is an enlarged, fragmentary view of a portion of the apparatus.
Referring now in detail to the drawings, a conductive core to (Fig. l) is advanced from one of two supply reels l2-l2 by a capstan l4, and is pulled through an extruder l5, a continuous vulcanizing tube 18 in tandem with the eX- truder it, around a guide sheave l9, and through a cooling trough by the dual capstan M. The extruder it forms an insulated covering 2 on the conductive core it to form an insulated conductor 2E, and the insulated conductor is con tinuously introduced into the vulcanizing tube it, which vulcanizes the covering 24 as the conductor 26 is advanced therethrough.
The conductor is advanced from the cap- Stan i l to a continuous takeup unit and is advanced over a distributor sheave 32 or a dist ibutor as either to a takeup reel mechanism 36 operable in one direction or a takeup reel mechanism 38 which is similar to the mecha- 323 but operates in an opposite direction. The distributor sheave is mounted rotatably on an arm as (Fig. 3) carried by a distributor front elewith porhead Z2 (Fig. 2) supported slidably on a shaft A l so that the distributor sheave 32 is moved along the reel st to distribute the conductor 26 upon the reel of the takeup reel mechanism which is rotated in a counterclockwise direction, as viewed in Fig. 3. When the distributor sheave 32 reaches its furthermost near the flange 53 position, actuating pin 6%; carried by the distributor head strikes an arm as of a limit ch i=3 to reverse the direction of rotation of the motor and the distributor screw 52, whereby the distributor screw moves the head 42 and the sheave 32 toward a flange 56 of the reel 6 to form another layer of the conductor on the takeup reel 6 When the sheave 32 reaches its furthermost pos tion near the flange ts, an actuating rod ll strikes an arm '52 of a limit switch it to again reverse the direction of rotation of the motor 65 and the distributor screw E2. The actuating rods 35 and H are mounted slidably in bosses l5 and '58 respectively, formed on a plate ll? of the distrbutor head 52. The positions of the rods and ii may be adjusted by a thumb screw extending through a tapped bore 82 in the plate is and tapped bores 88 and 83 formed in and 92, respectively, which are rigi ly secured to the actuating rods 35 and H. Thus, the length of throw of the distributor may be adjusted.
A hand wheel 85 is keyed to the shaft which carries two pinions, of which a pinion 95 (Fig. 3) is shown. The pinions St-Et engage the racks EL-52 of the guide rods 5Q5 l. The hand wheel 9% may be rotated to rotate the shaft 3% and the p nions 85-435 to move the slides 38-43 along tr e rods to the right to the left, viewed in Fig. thereby moving the distributor sheave 32 with respect to the takeup reel mechanisms 35 and 3B. A pivoted latch lil l may be actuated manually to lock the distributor t l in any desired position on the guide rods tail-5t. Normally, while the covered conductor 28 is wound on the takeup reel mechanism 3%, the distributor 3 is in the broken-line position thereof shown in Fig. 3, and the conductor 2% follows apath shown in broken lines to the reel 6%. When the reel 5d is almost filled the latch its is released and the hand wheel is actuated to move the distributor 3 to the full-line position thereof. This changes the path of the conductor from the distributor sheave 32 to the reel from that shown by the above-mentioned broken-line to the reel 6 to the path thereof shown in full lines. The portion of this path of the conductor '26 between points A and B forms a chord with respect to flanges l&9lcii of a reel iii! of the takeup reel mechanism 38, which reel is rotated when driven in a clockwise direction,
viewed in Fig. 3.
An electric motor H6 (Fig. l) of the takeup reel mechanism 38 then is energized to start the rotation of the reel HQ. The motor H5 rotates a centering cone Ed by a b the reel pin ill and an arm H8 in a clockwise direction, as viewed in Fig. 3, and a freely rotatable centering cone !22 (Fig. 4) connected to the reel lit by a pin 25 and a guard 52:! is rotated by the reel. The centering cone 222 is retated by the reel Hi3 rotates the guard i2 3 therewith. The guard lfi i carr es an L-shaped snagger 528 pivotally thereon and the snagger has a snagging notch 138 formed therein. The sngger IE8 is designed to slide through a slot 2'32 formed in the guard. 52-6. An arm lit of the snagger i223 carries a follower roller 33, and normally held by a spring 534 in a retracted position in which the snagging portion of the 52% does not extend beyond the near flange of the reel iii}. A presser earn 135 carried. by an arm 3 pivotally mounted on a bearing it'l, and is operable by a lever 53% to a position engaging the roller I33 to move the snagger iZS further upwardly, as viewed in Fig. 5, to a position extending beyond the inner flange of the reel Ht shortly after the snagger passes the point A (Fig. 3). However, as the snagger passes point A the cam does not push the snagger beyond the near reel flange his and against the spring its but acts to hold the snagger in its retracted position so that the snagger clears the conductor 25 whenever the conductor is near that flange of the reel as the snagger approaches the portion of the conductor 25 at the point A.
When the distributor sheave 32 advances the conductor 26, which subtends a portion of the flanges of the reel lid, to a position in which the conductor is near the right hand flange of the reel, as viewed in Fig. 4, and the lever 38 has been actuated to push the snagger against the spring 53 5-, the snagger clears the portion of he conductor at point A (Fi 3), is moved over the conductor between the points A and B, catches the portion of the conductor at B in the otch 239 (Fig. 7) and pulls the conductor downwardly, as viewed in Fig. 3. The takeup reel {i i continues to be rotated and to wind the conductor 25 thereon, and the portion of the conductor between the snagger and the reel 55 is moved downwardly. The inrunning reel E i and the snagger i2$ move the portion of the conductor therebetween downwardly hard against a shear blade i lii to sever the conductor.
The snagger E28 continues to rotate with the reel Hi? and the distributor 3 distributes the conductor 25 on the reel l H! as the snagger is rotated beyond the point B (Fig. 3) to somewhere near point C where the snagger moves out of engagement with the cam, and the spring E34 moves the snagger back to a position in which it does not extend over the flange of the reel i it. The snagger continues to hold the conductor so that the conductor is wound on the reel H5. The lever 33 then is released and the snagger is moved to its retracted position by the spring 234 to clear the portion of the conductor 25 being advanced to the reel HS. Thus, after the winding has been started on the reel Ht as described hereinabove, there is no danger of resnagging the conductor 26.
After the reel 5 ill has been filled the distributor 3 is moved to its broken-line position and the above-described operation in connection with starting and winding of the conductor 26 on the reel lid is repeated to shear the conductor and start the conductor on the reel 64 by means of a snagger and its associated elements which form a portion of the takeup reel mechanism 36, which is identical with the takeup mechanism 38 except that the mechanism is a left hand mechanism while the mechanism 38 is a right hand mechanism.
The motor H6 (Fig. 4) is mounted on a slide ill! mounted on a guideway I12, and a bearing ll l supporting the centering cone lZ-fi also is carried by the slide llil. After the reel llil has been filled and the conductor 26 is severed therefrom, the motor lie is deenergized and a linkil is moved so as to actuate a valve 18 to supply air under pressure to the right hand end of a cylinder l fi, as viewed in Fig. 4, and to pivot a latch i532 secured rigidly to a shaft I8 out of a slot 588 formed in the slide Hi] so that the slide may be slid to the left by a piston lei fastened to the slideto free the reel HE; for removal. After an empty reel to be substituted for the reel Hi! has been positioned between the centering cones I28 and I22, the linkage H6 is moved. to actuate the valve I18 to supply air under pressure to the left end of the cylinder 5'85 and to permit the latch 182 to move into the slot I 88 whenever the slot N38 is moved thereover. The piston then moves the slide 18 to mount the empty reel on the centering cones I20 and I22, and the latch moves into the slot H38 to latch the slide in an operative position.
Operation The insulated conductor is advanced over the sheave 32 of the distributor mechanism 3%, which is in its broken-line position, as viewed in Fig. 3, to the reel 64 of the takeup reel mechanism 33, the motors 66 and 65 are started. the reel 55 is rotated, and the distributor as distributes the conductor 23 in layers extending from flange to flange of the reel When the reel 54 is almost filled, an operator of the apparatus releases the latch Hi l mov s he distributor mechanism 3 to the left to its full-line pos tion. The operator then starts the motor HEB (Fig. to rotate the reel iii in an inrunning direction with respect to the direction of rotation of the reel es. and the distributor L l continues to distribute the conductor evenly upon the reel When the reel 54 is filled, the operator a the lever 13% (Fig. 4) to swing the cam iBfi 1. left, as viewed in Fig. 4:. The snagger 523 then is moved from a position at the edge of the right hand flan e of the reel l H! to the position of the snagger 28 shown in Fig. 5 after the snagger has passed point A (Fig. 3) and has not yet come to point B. After the sna ger is rotated past point C the follower roller L33 moves it back to a positicn in which it does not extend beyond the inner flange H39 of the reel Hi! When the distributor sheave 32 moves the conductor 2 to the right hand flan e of the reel i it, as viewed in Fig. 4, the snagger 12?? catches the conductor 2% and moves the portion of the conductor between the snagger and the reel i i against the shear blade 14%, which severs the conductor.
The lever I33 then is released so that the spring 535 moves the snagger 25 to its retracted position. The snagger continues to hold the newly formed end of the conductor and carries it around the drum of the reel l iii, and the distributor 3 distributes the conductor on that reel.
The operator then stops the takeuc reel mechanism 35, removes the filled reel li i therefrom, end substitutes an empty reel identical with the reel 84 for the reel '54. When the reel l iii i filled with the conductor 26, the switchover to the empty reel of the takeup reel mechanism is effooted by a snagger and its associated elements of the reel mechanism which are identical with. but of opposite hand from the snagger lES its associated elements of the talreup mechanisn 32, after moving the distributor 34 to its brokenline position, as shown in Fig. 3, so that a por tion of the conductor 25 between the sheave 32 and the takeup reel lid s in a plane chordally intersecting the flanges of the reel of the takeup mechanism 35 to permit the conductor to be snagged.
The above-described talaeup mechanism serves. to continuously take up the conductor 2% witho t interruption in or slowing of operation so that the operation of the extruder l6 and the vulcanization is not even slowed down. The transfer from one takeup mechanism to the other is almost completely automatic inasmuch as the only manual effort. necessary to make a transfer from too one takeup reel mechanism to the other is to move the distributor mechanism 34 to the proper position, to start the idle takeup reel mechanism, to actuate the cam of the idle takeup mechanism and to release the cam after the transfer has been made. There is no danger to'an operator of the apparatus since the snaggers are covered and accidental contact therewith is blocked.
