Definitions

  • a wire is automatically tr-ansferred from a full take-up reel to an adjacent empty take-up reel during as snagging operation.
  • a wire distributor is moved back and forth a full stroke in a path between spaced planes extending normal to the reel axis adjacent the reel flanges to uniformly distribute the wire in layers on the reel on which the Wire is being wound.
  • the distributor stroke is shortened just before the reel is full whereby the wire is confined by the distributor to a single fixed shorter path near the inside reel flange to facilitate the transfer of the wire to the adjacent empty reel.
  • Field of the invention is concerned with the manufacture of wire. More particularly, the invention is concerned with taking up wire continuously after a processing operation such as the extrusion of insulation on a wire wherein the wire is transferred from a full take-up reel to an adjacent empty take-up reel.
  • the distributor shifts L from its immediate position overlying the full reel to a corresponding position overlying the empty reel. It is during the transfer that the snagging and cutting of the wire takes place. It has been found that the most favorable position for transfer is when the wire is close to the inside y flange of the full reel since in that position the wire has no difficulty in clearing the previously mentioned fender. The most unfavorable position for transfer is when the wire is adjacent the outside flange of the full reel.
  • Hauer Patent 2,971,711 One proposed apparatus for assuring that a wire will be in a favorable position for transfer is disclosed in Hauer Patent 2,971,711.
  • the distributor When a take-up reel is almost full the distributor remains in a fixed position adjacent the inside flange and the last turns tend to pile up at that position.
  • the arrangement of that patent for accomplishing the favorable position of transfer is somewhat involved. Further, it is preferable that no pile up ICC occurs adjacent the flange since a pile up of wire could cause tangling of the wires 4and wire breakage particularly when wires of fine gauge are being processed.
  • the Hauer patent does not disclose a curved guide and the main object in providing a favorable wire transfer position is to minimize tension variation on the wire.
  • the timing is arranged such that if the distribution point at the predetermined time is beyond the intermediate limit switch the distributor moves to the outside limit switch, is returned in the opposite direction, and thereafter is confined to the region betwen the intermediate limit switch and the inside limit switch.
  • the stroke of the distributor has been shortened to 'a path lying towards the inside flange of the reel.
  • the intermediate switch is placed close to the inside limit switch.
  • the reel take-up speed and timing of the distributor is such that just enough wire remains to be wound on the reel after the intermediate switch has been cut in to assure that the wire may move from the intermediate switch if Iat that position to the outside limit switch and back beyond the intermediate limit switch.
  • the invention is not limited to take-up apparatus using a fender or to wire since it may conceivably be used for winding other continuous elongated articles, strand material generally, for wire pairs, and even for small size cables. Further, the invention may be used to control the final position of a wire on a single take-up reel.
  • FIG. 1 is ya schematic diagram of a wire take-up apparatus
  • FIG. 2 is a schematic diagram showing a wire in its most unfavorable position for transfer
  • FIG. 3 is a schematic diagram showing a wire in its most favorable position for transfer
  • FIG. 4 is a schematic diagram, particularly illustrating the lsnagging of the wire by the empty supply reel snagger plate
  • FIG. 5 is a schematic :diagram of the new distributor control
  • FIG. 6 is a drawing showing the distributor carriage driving system
  • FIG. 7 is a schematic drawing of the electrical control circuit for the distributor control.
  • FIG. 8 is a pictorial illustration of a portion of the control circuit.
  • a wire 10 is shown ⁇ drawn by a capstan unit 11, which includes a tach generator 9, from an extruder apparatus 12 after which the wire proceeds about an accumulator 13 comprising a pair of sheave banks 14 and 16 about which the wire is looped.
  • rl ⁇ he wire engages a follower sheave 20 which drives a pulse generator 17 for measuring the length of the Wire being fed by sending an impulse to an electronic counter 18 for every two feet of wire.
  • the wire moves about a centrally located sheave 19 to a distributor 21 and then to the particular take-up reel 22 or 23 taking up the wire.
  • the reels are respectively ldriven by motors 24 and 26.
  • a potentiometer 27 coupled to the accumulator 13 regulates the speed of the particular reel 22 or 23 on which the wire is being wound.
  • the take-up speed must Ibe reduced as the :diameter of the winding builds up.
  • the wire is looped back and forth about the sheave banks 14 and 16 in a conventional manner.
  • Upper sheave bank 14 is maintained in a fixed position while lower sheave bank 16 is movable upwardly and downwardly in slideways (not shown) and by means of a chain drive (not shown) controls the potentiometer 27 which in turn may control one or the other eddy current clutches (not shown) associated with motors 24, 26.
  • the position of the lower sheave bank 16 is a measure of the wire tension and the diameter of the supply on the reel taking up the wire.
  • the tach generator 9 of the capstan unit 11 generates a continuous voltage signal to control the eddy current clutch of an empty reel when that reel is brought up to speed on operation of relay R as will be explained.
  • distributor 21 is shown in the most unfavorable position for transfer from the full reel 22 to the empty reel 23.
  • the reel drive shafts 25, 30 have respectively attached thereto the snagger plates 28, 38 having teeth 29.
  • Intermediate the reels is a curve-d guide 31 including an upper guard 32 and a lower narrower guard 33.
  • the upper guard 32 overlies the teeth 29 of the snagger plates 28, 38, while the lower guard 33, which is a continuation of the upper guard, is intermediate the teeth 29 of the respective snagger plates.
  • the empty reel 23 Since the core surface speed at the core 37 of reel 23 must be matched to the linear speed of the wire the empty reel 23, prior to transfer, is brought up from zero speed to the wire linear speed. Since the reel 22 is in the full condition and the diameter of the winding is substantially at the maximum condition, it is being driven at a speed considerably less than the speed of the empty reel. The difference in revolutions per minute between the empty reel and full reel is approximately 2.5 to l. As a consequence, the teeth of snagger plate 38 are moving much faster than the teeth of snagger plate 28. The portion of the wire snagged by a tooth of snagger plate 28 is already beyond the lower guide when a tooth of the snagger plate 38 snags another portion of the wire.
  • the snagger tooth of plate 38 holding the wire portion is moving at a much greater speed it moves into substantially the same rotary position as the tooth engaging the other portion of the Wire just prior to engagement with the knife 34.
  • the section of the wire between the snagged plates is substantially parallel to the reel axes as the wire is severed. While the guide 31 assures that there will be no stretching and breaking of the wire during snagging due to the relative speeds of the snagger plates, or premature engagement with the teeth, it does present a. crossover problem as has been described.
  • one pair of limit switches LSlL, LSZL controlled the wire distributor 21, for one take-up reel, for example, reel 22 and a second pair of limit switches, LSIR, LSZR, controlled the wire distributor 21 for the other take-up reel 23.
  • the limit switches control a pair of solenoids DRS, DLS, FIG. 7, which in turn control a four-way valve (not shown) to operate the piston rod S7 of hydraulic cylinder 56 back and forth.
  • the piston rod 57 drives distributor 21 back and forth along rods 53, 54 as the wire is wound on a supply reel.
  • the piston rod 57 of the hydraulic cylinder 56 is coupled by means of a bracket 58 to plate 59 attached to the movable carriage 61 which supports transfer air cylinder 52 and is mounted on the rods 53, 54.
  • the air cylinder 52 is operated or unoperated, always a full stroke, to drive the distributor 21, through its piston rod 90, rapidly to the right or left along rods 53, 54 to enable the distributor 21 to distribute the wire on one reel or the other.
  • the front end of piston rod is coupled to distributor 21 as shown in FIG. 7.
  • the distributor of course, is shifted from the full reel to the empty reel.
  • the distributor includes a cam 60 which operates the limit switches LSIL, LSZL, LSlR, LS2R.
  • the cam 60 additionally controls a centrally located directional control limit switch LSDC.
  • the positions of the limit switches may be adjusted longitudinally along rod 65 as desired.
  • Eye guide 71 and pins 72 assist in guiding the Wire to the reel being wound. As viewed in FIG. 2, when the distributor is in the righthand position overlying reel 22 the axis of eye guide 71 is in a plane extending normal to the reel axis and when the distributor 21 is in the lefthand position the eye guide lies in a similar plane parallel to the other plane.
  • intermediate limit switches LSILL and LS2RR have been added. These limit switches are'likewise under the control of cam 60 carried by the distributor 21. When cut in, the intermediate limit switches perform the function of the outside limit switches LS1L and LS2R. It is preferable that the intermediate limit switches are about 1%" from the inside limit switches LS2L and LSIR. This distance could be from the respective center lines of cam engagement. The full core length of a small size reel is 4%" and of a large size reel is /3". Obviously, the position of the intermediate limit switches can be adjusted to meet varying operating conditions, the dimensions mentioned being only by way of example.
  • Directional conductor 70 is operated by the cam 60 on transfer of the distributor 21 from a full reel to an empty reel, as later described.
  • a first preset counter control closes contact PTR to start the operation of timer ET which is set for 28 seconds and causes the operation of empty reel drive relay R.
  • the latter relay starts the drive of the empty reel 23 which is brought up to the required core surface speed to match the linear speed of the wire which is 4500 feet per minute.
  • Relay R renders the tach generator 9 effective to send a continuous voltage signal to control the eddy current clutch of the empty reel.
  • the counter After the 28 second period has elapsed, the counter will read 27,850 feet and 2 seconds will remain which is the time necessary to take-up the last 150 feet of wire.
  • the 2 second time interval is sufficient for the cam 60 to move from the intermediate switch LSlLL, if at that position, completely to the left, then back to the right beyond intermediate limit switch.
  • the cam had been between intermediate limit switch LSILL and inside limit switch LS2L at the end of the 28 second interval it will remain in that region.
  • the second preset counter control closes contact PTC, the transfer solenoid TS is operated and the distributor 21 ⁇ is transferred to the empty reel. Even if the distributor remains between the intermediate limit switch LS1LL and inside limit switch LS2L only a relatively small amount of wire remains to be wound and it is uniformly distributed between those switches without pile up.
  • the distributor 21 When the distributor 21 is transfered from a full reel to an empty reel as explained, it is moved so rapidly by air cylinder 52 that it assumes a position overlying the empty reel almost identical to the position it assumed overlying the full reel yat the time of transfer.
  • directional control 70 As the cam 60 engages centrally located directional limit switch LSDC, on transfer, directional control 70 is operated, the counter 18 is reset, the timer ET is reset, and the control of the empty reel by tach ⁇ generator 9 is switched to potentiometer 27.
  • the directional control also conditions suitable contacts (not shown) for controlling the operation of transfer solenoid TS. For example, when the transfer solenoid TS -for air cylinder 52 is operated the distributor 21 moves from left to right on operation of contact PTC.
  • the control is such that when the second preset control -PSCZ operates in counter 18 with the distributor in the right position, contact PTC is opened, and the transfer solenoid TS is de-energized to drive the distributor back to the left, overlying the empty reel which replaced the previously wound reel.
  • the limit switches LSIR, LSZRR and LSZR operate respectively in the same maner as their counterpart limit switches LSlL, LSILL, and LS2L.
  • timer ET could be eliminated and its function performed by a third preset control.
