Definitions

  • the wire hooking member is mounted on a disc coaxial with the coil and capable of rotating relative to the drive shaft thereof.
  • this disc is coupled to the drive shaft and the spool, and rotates with them but after the transfer, one can act on it a brake, so that it describes a relative movement of recoil by unrolling slightly the wire segment adjacent to the end retained by the fastening member. Under the effect of centrifugal force, this segment of wire is released from the drum of the spool and forms a loop, which is intended to be collected in a chute, integral with the hook-carrying disc.
  • a hook-carrying disc secured to the drive shaft and an annular member provided with a chute and capable of advancing axially above the spool of the spool by opening the retaining hook of the initial strand of the lining.
  • the loop which then forms under the effect of centrifugal force is free at its end and engages radially in the chute in the advanced position. This can then be brought back to the retracted position so as to free the drum from the spool.
  • the centrifugal force exerted on the loop which is formed by said recoil movement can not ensure its engagement in the chute.
  • the chute moves axially relative to the hook-carrying disc by unhooking the wire in order to release the loop, it can be collected in the chute, but the fact that it is no longer hooked by its end cancels the effect that could be expected from the engagement of the loop in the chute.
  • the turns adjacent to the cheek located on the side where the transfer device is located exert traction forces. on the initial strand when they are deposited. The loop formed by this initial strand is gradually drowned in the lining, and when the latter is complete, the initial strand no longer has the free segment which is desirable.
  • the object of the present invention is to remedy this defect by creating a mechanism capable of equipping double winders with automatic transfer operating at high speed and capable of ensuring the forced formation of an initial strand of predetermined length accessible outside. of the lining, this formation being caused after the beginning of the lining of the reel by a control acting from the outside on the winder.
  • the present invention is based on the idea that it is necessary to provide not only a hook-carrying disc capable of performing a backward movement relative to the drive disc, but also a third annular member, capable of to effect a relative displacement distinct from that of the hook-carrying disc and acting so as to collect and positively retain the loop formed by the initial strand during the relative backward movement of the hook-carrying disc.
  • the present invention therefore relates to a double winder with automatic transfer for the continuous winding of a metal wire on spools, comprising two spool supports having parallel drive shafts and each equipped with a mechanism for hooking the initial strand of a lining, this mechanism comprising a hook-carrying disc provided with a hook, capable of fixing the end of the initial strand, a drive disc secured to one of said shafts and coupled to a coil intended to receive said initial strand, and an annular member extending around the periphery of the cheek of said spool, the hook-carrying disc, the drive disc and said annular member being coaxial with said shaft and driven in rotation with it, and the mechanism further comprising braking means capable of producing at the start of each winding operation a relative recoil of the hook-carrying disc relative to the drive disc in order to lengthen the initial strand.
  • this winder is characterized in that said annular member is distinct from the hook-carrying disc, in that it is connected to the drive shaft and to the hook-holding disc by a planetary gear train in which the hook-carrying disc acts as a planet carrier, in that disengageable coupling means normally join the hook-carrying disc, the annular member and the drive disc, in that control means are provided for simultaneously controlling a momentary disengagement of said coupling means, and the actuation of the braking means, said annular member then effecting under the action of the planetary gear a rotary movement relative of limited amplitude, distinct from said relative recoil, relative to the drive disc and in that said annular member has a portion of surface coaxial with the drive shaft and shaped so as to retain the loop formed by the initial strand at the time of said relative recoil and said relative rotary displacement, so that it plays the role of a deployment member.
  • the winder is characterized in that said annular member is distinct from the hook-carrying disc, in that it is coupled to the latter so as to be integral therewith in rotation, and is carried by support means which allow it to effect an axial relative displacement of limited amplitude with respect to the drive disc and the hook-carrying disc, in that disengageable coupling means normally join the carrier disc hook, the annular member and the drive disc, in that control means are provided for simultaneously controlling a momentary disengagement of said coupling means, the said relative axial displacement and the actuation of the braking means, and in that said annular member is provided with a chute which has a portion of surface coaxial with the drive shaft and shaped so as to retain the loop formed by the initial strand at the time of said recoil r elatif and said relative axial displacement, so that it plays the role of a deployment member.
  • a coil 1 comprising a cheek 1 a and a barrel 1 b is supported by means of a retractable mandrel 2 coaxially with a shaft 3.
  • This shaft is a drive shaft. It is coupled to a motor device (not shown), the speed of which can be adjustable and a bearing 4 supports it relative to an upright 5 which is fixed and forms part of the frame of the machine.
  • a motor device not shown
  • the speed of which can be adjustable
  • a bearing 4 supports it relative to an upright 5 which is fixed and forms part of the frame of the machine.
  • another pivoting device is provided at the other end of the spool 1 and the winding machine also comprises a second spool support capable of receiving another spool such as 1 in order to fill the spools alternately on one of the supports and on the other.
  • the automatic transfer mechanism is not shown in the drawing. It can be of any type known in this field of technology.
  • the cheek 1a of the coil is made integral with the drive shaft 3 by a friction lining 6 of annular shape which is carried by a drive disc 7 fixed to an annular intermediate piece 8 which is welded to the shaft 3.
  • This part 8 has, on the one hand, a guide groove 9 in which is engaged the internal edge of the opening of a disc 10 which constitutes the cheek of a deployment member, as will be seen more far.
  • the ring 8 also has a pinion toothing 11 and forms the planetary pinion of a gear.
  • the planet carrier disc 12 of this gear is mounted on the shaft 3 by means of a bearing 13.
  • the disc 12 and the disc 10 are kinematically linked to each other by the or the satellites 14. If they are locked relative to each other, they are driven by the shaft 3 at the same speed as the coil and the assembly rotates as a single member.
  • the two discs are released relative to each other, and if, by an external mechanism, one of them is imposed, for example on disc 12, a rotational speed less than that of the shaft 3, for example by braking it, then the disc 10 is driven at a speed different from that of the disc 12 and that of the shaft 3, this speed being given by the gear ratios of the elements described .
  • the discs 12 and 10 are made integral with each other by means of a locking mechanism which comprises a rocker 18 pivotally mounted on the disc 10, a spring 19 and a circular ramp 20 with notches 21 (fig. 2 and 4).
  • the notched ramp 20 is fixed coaxially to the shaft 3 on the disk 12.
  • FIGS. 4a, 4b, 4c it has at least one interruption forming the notch 21 preceded by an entry 21 a whose width is slightly greater than the width of the lever 18, also visible in these figures.
  • Only one notch is shown in the drawing, it is obvious that, depending on the embodiment which is desired, it is possible to provide two or more equidistant notches along the ramp 20.
  • the disc 12 has a hole in which is engaged a release finger 22. All these fingers 22 are carried by an annular plate 23 coaxial with the coil and whose internal edge extends between the jaws of a brake 24 capable of be moved in the axial direction.
  • the rocker 18 remains engaged in the notch 21 and the two discs 10 and 12 are integral with each other and rotate at the same speed as the shaft 3, the satellite or satellites 14 playing the role of keys .
  • the brake assembly 24 is moved to the right while tightening the two jaws against the annular plate 23, the release fingers 22 pass through their openings in the disc 12 and press on the lower ends of the rockers 18 by releasing them from the notches 21. From this moment, the two discs 10 and 12 are unlocked relative to each other and, like the disc 12 is braked via the fingers 22 and the annular plate 23, its speed relative to the shaft 3 decreases.
  • the disc 10 is then driven via the satellites 14 and will rotate relative to the shaft 3 and relative to the disc 12 at a speed which depends on the ratios of the gears.
  • the direction of rotation of the disc 10 is such that the rocker 18 moves in the direction of the arrow 25 relative to the disc 12.
  • the disc 10 When the disc 10 has moved over a certain arc, it will end up in an entry 21 a and in front of a notch 21 so that it will again block the two members 10 and 12 not relative to each other if the release fingers 22 have been removed in the meantime.
  • the unlocking situation On the other hand, if these fingers have not been removed, the unlocking situation will be prolonged and it can be made to last as long as desired.
  • the disc 12 is provided with a peripheral wall 26 of cylindrical shape visible in FIGS. 1 and 2. At one or more points around its periphery, this peripheral wall is equipped with a hooking member 27 which pivots about an axis 28 parallel to the axis of rotation of the coil. This axis is mounted in a support stud 29 fixed inside the cylindrical wall 26 and the latter has an elongated notch 30 in line with this stud in order to provide the space necessary for the operation of the hooking member 27 which, under the effect of the centrifugal force, will be urged outwards and press against the oblique edge of the member 26 at the location where the elongated notch 30 is located.
  • the disc 10 constitutes the cheek of a deployment drum. It is also provided at its periphery with a cylindrical wall designated by 31 in FIG. 1. This wall constitutes the deployment member on which the segment of wire intended to form the initial strand is wound. It is provided with a peripheral rim 32 which has one or more cutouts 33a limited at one end by a spout 33. The spouts 33 and the hooks 27 are in coincidence when the discs 10 and 12 are locked one with respect to the other as shown in fig. 1. The details of the notch 33a and the spout 33 are also visible in FIG. 3.
  • Figs. 5 and 6 illustrate the operation of the winder described above.
  • fig. 5 we can see, diagrammatically shown, two coils 1 and 1 'which are mounted on the winder and driven in rotation in the direction of the arrows 34 and 34 ' .
  • the figure shows two different situations which occur in a very short time interval at the time of transfer.
  • the wire 35 passes over a pulley 36 and, in the first situation, it extends in a straight line from the pulley 36 to the lining of the coil 1 'which is supposed to be finished. As can be seen, it is led so as to pass almost tangentially to the drum of the coil 1.
  • the hook 27 and the spout 33 of the drum 31 are always in relative positions which correspond to the joining of the two parts 12 and 10 (fig. 5).
  • This situation represents the starting situation for the implementation of the deployment mechanism. If, from this situation, the brake 24 is actuated, so that the release fingers 22 move axially and raise the rockers 18 to bring them into the position of FIG. 4b while braking the support 12 of the hook 27, then the support 12 will move relative to the coil 1 in the direction of the arrow 37 (fig. 6a). In other words, it will be braked relative to the coil.
  • the drum 31 as we saw previously, it will move in the same relative direction as the support of the hook 27, but with an even greater speed.
  • arrow 38 represents, the length of which is greater than that of arrow 37.
  • the drum 31 undergoes an even more pronounced slowing down than the support 12.
  • These relative movements lead the spout 33 to approach the hook 27, hook the segment of wire which extends between the hook 27 and the drum of the reel and which relaxes as a result of the recoil of the support 12 relative to the reel and pass beyond the hook .
  • Fig. 6b shows for example the situation which arises when the spout 33 has arrived in an orientation which is approximately 90 ° behind that of the hook 27. It is obvious that this situation may arise when the reel 1 has carried out several turns from the situation in fig. 6a and in the direction of the arrow 34.
  • the situation in fig. 6b can be extended until the time when the deployment drum is joined to the hook support, as will be seen above.
  • the ramp 20 has two diametrically opposite notches 21, the rocker 18 mounted on the drum 31 will block the two members relative to each other when the spout 33 is almost 180 ° from the hook.
  • the length of the wire reserve will correspond in each case to the length of the arc which extends between the hook 27 and the spout 33 at the moment when the rocker engages again in a notch 21.
  • the hook-carrying disc 10 can carry only one hook 27, and the peripheral rim of the drum 31 can also have several notches 33a forming at one of their ends a beak 33. If the number hooks 27 and spouts 33 is chosen in accordance with the length of the arc on which the wire reserve extends, the deployment mechanism can return to its final position when lining a new coil. Each final position constitutes an initial position corresponding for example to that of FIG. 2 and from which the relative displacement of the spout and the hook relative to the spool holder can occur.
  • the deployment mechanism comprises a deployment drum coaxial with the spool and linked to the hook support, on the one hand, by a planetary gear, and on the other hand, by a lock that can be actuated from the outside after the coil lining has started. It is obvious, however, that any other embodiment in which a deployment mechanism acts so as to constitute a reserve of wire by hooking two end points of a segment of wire situated at the initial end of the lining, this segment of wire being extended between these two attachment points so that the length of the wire reserve is determined, also falls within the scope of the present invention.
