Description

The present invention relates to a cabler comprising a series of

  coils mounted crazy on the machine shaft and that work for wiring and for

the winding of new wire.

  Machines of this type are used to wire several wires together or to wire several wires around the same central core, for example around a cable, the conductor of an electric cable or a similar element of great length which is put in continuous motion

parallel to its axis.

  In general, these cords comprise several hollow shafts aligned with each other, each of which is free to rotate carried by supports and rotated by a suitable driving force, at least one pair of coils mounted crazy but irremovable on the shaft , an element or arm unwinding used to unroll the thread of a

  coil and appropriate guide pulleys.

  On each shaft, during wiring, the wire of one of the coils of the pair of coils mounted crazy on

  this tree progressively progresses under the action of the

  adjacent unwinder which is attached to the

  during the wiring phase through the hollow shafts, however, a pulling action is exerted on the wires.

  by appropriate drawing means.

  The second coil of the pair, which is adjacent to the coil being wired on the same shaft is on its side rotated by other motor means and wound on itself turns of a new wire which must be used later in the wiring when the first

coil will be exhausted.

  On the machines in question, it is necessary to provide the wire with a correct winding voltage with appropriate braking devices and it is equally

  essential to exercise when shutting down the machine an energy

  braking action, a value much greater than that which is necessary during the unwinding of the wire and which must be able to stop the coils at the instant when the

machine stops.

  In fact, in the case where the direction of rotation during unwinding matches that of the arm, so that this arm always tends to drive the coil in rotation, it is observed that the absolute speed of the coil is equal to that of the arm, for example of the order of 600 to 700 rpm, plus that

  the unwinding, for example of the order of 50 rpm.

  On the other hand, in the case where the direction of unwind rotation is the opposite of that of the arm, the absolute speed of the spool is equal to that of the arm minus that of the spool.

  unfolding but it is always very high anyway.

  In the cablers in question, it is therefore always

  days necessary to provide a device that, apart from the function of stretching the wire; is always able to transmit a high braking torque to the coil at the time of stopping the machine since the speeds involved in the rotation of the coil are not only the unwinding speed of the coil but also the speed

  ten times higher.

  The search for an optimal solution is com-

  the fact that it is a question of fully satisfying not only the conditions which the machine must fulfill in normal operation in order to ensure correct cabling, but also those which are generated by the stops of the machine which may be due to patterns, with means that must at the same time be adapted to

  automatically switch from the moderate braking action required

  for the unwinding of the wire with the energetic braking action which is necessary when stopping the coil and,

  which must above all possess the additional characteristic

  to ensure a rapid suppression of the braking of the coil to allow this coil to pass the phase

  wiring in the refolding phase of new wire. -

  The solution must also be applicable

  in a simple and economical way to a series of reels

  very large and which can represent, by

  example eighteen pairs of coils or even more.

  Moreover, it is easy to understand that, in the above-mentioned blasters, because of the speeds involved, it is necessary to solve the problems posed by the great centrifugal forces that may compromise or distort the action of the means which may be provided for the voltage

wire and braking coils.

  The Applicant considers that the improvements to be made to the cablers in question must guarantee both the immediate braking of the coils at the time of shutdown.

  of the machine, a tension of the wire during self-wiring

  applicable to the series of central reels

  by the trees, and the immediate suppression of the braking

  coils to move to the rewind phase.

  The object of the invention is therefore to achieve a

  central reel blower capable of resolving

  simultaneously the aforementioned problems with improved productivity. The invention relates to a multi-wire machine comprising a series of pairs of coils used to wire and wind a new wire, which are mounted idle on at least one hollow shaft, free to rotate and supported by a support, a pair discs mounted idle on the shaft in axially inner positions relative to a pair of coils, each of these disks being secured to the shaft when the contiguous coil is in wiring phase and the disk comprising a member or arm unwinder equipped with its own pulley and serving, in combination with a group of pulleys, to guide the thread that unwinds from the spool towards the interior of the hollow shaft, where the thread is subjected to traction, and is driven to the interior of the hollow shaft towards the wiring point, this cabling machine being characterized in that it comprises means of connection between coil and disk capable of determining a relative movement controlled between

  coil and disc during the curing and blocking phase

  bleuse, means capable of detaching the reel from the disk during the preparation for the clearance of the reel in its new wire relining phase and during this phase, said connecting means comprising a band brake wound a predetermined arc around the periphery of a suitable brake drum belonging to the coil, the ends of the strip being respectively combined with a

  point of the disc and at a first spring, possessing

  predetermined characteristics and mounted on the disk appropriately to transmit to the web a braking torque capable of stopping the spool, loaded with wire and driven to

  unwinding, a group formed by a lever mechanism that oscillates

  around a pivot carried by the disk according to the tension of the thread, which tension acts on a pulley associated with a first arm of the lever, and the counteracting action of a second spring having predetermined characteristics, mounted on the disk and one end of which is attached to the second arm of the lever, and a transmission element serving

  to transmit a higher thread tension to the force anta-

  second brake spring of the belt brake lever mechanism for varying braking of the belt on the drum of the reel and automatically adjusting the tension of the unwinding wire to a constant value, said means provided for disengaging the reel from the disk when the machine is stopped comprising a device permanently associated with the disk, equipped with an element which acts on one of the ends of the first spring with a traction action during the wiring phase and capable of canceling

  the arrow of the first spring when the machine is stopped.

  It follows from the foregoing that the characteristics

  fundamental features of the invention include a coil-to-disk band link, a

  automatic braking regulation during the phase of

  and a braking suppression device to allow the coil to move quickly from the state of

  wiring in the refitting state of new wire.

  Said tape linkage integrated with the automatic voltage regulator determines a constant value of the wire tension in the relative movement between coil and disk, in particular because, thanks to the aforementioned characteristics during the transitional phase which precedes the stopping the machine, the action of the wire tension transmission element at the belt brake decreases constantly and that the braking effect of the first spring

  believes correspondingly constantly until the cancellation

  relative movement between disc and coil.

  The braking suppression device is the complement of the aforementioned band connection, in that, during the wiring, the function of charging the first spring, it then allows, when the machine

  is stopped, the suppression of braking between disk and

  by the relative approximation of the ends of the first spring. In a preferred embodiment which is particularly suitable for limiting the effect of centrifugal forces on the voltage regulation device of the invention.

  relative to the axis of rotation of the machine.

  In another embodiment, the machine

  is characterized in that the wire being de-

  before passing over the oscillating pulley of the

  Lever mechanism, is directed to a deflection roller

  placed parallel to the axis of the coil, immediately

out of the cheek of it.

  The figures of the annexed drawing, given as an example

  not limitative, will make clear how the invention

can be achieved.

  Figure 5 shows a detail of the device of

  suppression of braking of the coil.

  The invention is applicable to machines for

  one-wire cable manufacturing and also several

  two layers of wire in alternate directions and / or with different pitch.

  The description given below is made about

  of one of the various applications of the invention, for example

  ple about a machine 1 (Figure 1) for wiring several son 2 around a central core, or by

  example, to form the screen around the central part 3 cons-

  staked by the conductor and its insulation in a cable

  electric power transmission.

  The machine is composed of several units 4 in number equal to the wires to be wired and each unit comprises a shaft 5 (FIGS. 1, 3) internally hollow, free to rotate and supported by a central support 6, a pair of coils 7,

  8 mounted crazy on the shaft on the sides of the support, used

  simultaneously to wire and wrap wire, with

  permutation of their functions during the successive phases

  sive, a pair of disks 9, 10 mounted crazy on the tree

  relative to the reels, an unwinding element or arm 11 carried by each disc provided with its own pulley 12, and intended to unroll the thread of the reel and to guide it, in combination with another pulley 13 integral with the shaft rotating, within this shaft, a single wire feeder 14 (FIG. 1) which supplies the wire to be wound alternately on one or the other of the coils of the pair of coils 7, 8, and a motion transmission device for transmitting the movements to the coils being wound.

  The units 4 of the machine 1, which are

  to simplify the number of two, present their

  bring the advantage of linking the final part of the

  the thread that unwinds from the spool 8 during the creeling over the coil 7 ', adjacent which is part of the other unit 4, and which was filled during the wiring phase

  of the coil 8 by means of the distributor 14.

  An appropriate service shaft 15 causes the ar-

  5 in rotation, by means of gears or other equivalent transmission means provided in the supports 6, and at the same time drives the discs associated with these shafts by

  appropriate means during the bobbin wiring phases.

contiguous neighbors.

  All the units 4 are included (FIG. 1) between an unwinder frame 16 which provides the core and a final station 17, which comprises a distributor plate 18 for distributing the threaded threads 2 into corresponding holes and which rotates integrally with the tree of the last unit, a die 19 fixed to a base 20 and known means of

  traction and reception (not shown).

  The wires and the core are thus guided inside the series of shafts 5 and subjected to the traction exerted by the

drawing means.

  Naturally, in the case where the machine is used

  for the manufacture of multi-layered cables

  yarn, for example two layers of yarn, the units of the ma-

  are divided into two successive groups, one per layer, each group having units which have different directions of rotation and speeds than those of the units of the other group, depending on whether they are meaningless alternate or not, each group being further provided with its son dispensing plate and the corresponding die. The distributor 14 of the wire that is to be wound alternately on one and the other of the coils of the same pair and the mechanism for transmitting the movement to the coils in the winding phase may be identical to those which have been described in the Italian patent application

  No. 26,952 A / 79 in the name of the applicant.

  In particular, it is briefly recalled here that the distributor 14 comprises an arm 21 capable of rotating at an angle of 1800 to pass from one to the other of the coils and which can move parallel to the axis of the machine on a stroke equal to the distance between the cheeks of a reel, with the aid of this arm 21, an end pulley 22 is moved to guide the wire, which comes from a reel or a

on the spool of the machine.

  The drive mechanism of the reel being wound may comprise a central shaft located between

  the discs, moved by a motor independent of the main shaft

  solution, special means of gearing are also provided.

  teeth with the teeth interposed between the small lateral shafts and the central shaft, these means being exposed in detail in

  the aforementioned patent application and their description being omitted

  in this memo to simplify the presentation.

  The basic characteristics will now be described.

  of the invention, illustrated in detail in Figure 2, and more specifically, the connection means between coil

  and disc which are intended to determine a relative movement

  controlled circuit for ensuring the correct tension of the thread during the wiring phase and for locking the spool on the disc when the machine is stopped, and the means for separating the spool from the disc during preparation for the authorization of the coil in its relining phase of

new thread and during this phase.

  These means, which are identical for all the units of the machine, are described with reference to the coil

8 and the disk 10 of Figure 1.

  Said connection means comprise (FIG. 2) a belt brake 23 which acts on the spool 8, a lever mechanism 24 responsive to variations in the tension of the thread being wound on the spool 8, an element 25 interposed between the spool lever mechanism 24 and the band 23, intended to transmit a variation of the tension of the yarn during the unwinding of a value greater than a predetermined value, an element able to vary the braking exerted by the strip on the reel and, this way, to automatically adjust

  the tension of the yarn running on a value practically

tically constant.

  The strip 23 is wound on a predetermined arc around the periphery of a suitable brake drum 26 of the coil, one end 27 of this strip being attached to a fixed point of the disk 10 and the other end 28 being

  subject to the action of the first jurisdiction 29 whose characteristics

  ticks and the mode of editing on the disc are arranged to

  transmit to the band a braking torque capable of stopping

  the reel, loaded with its thread and rotating at the speed of

  the moment the machine stops.

  In a preferred embodiment, the belt brake 23 comprises a plate 30 which rotates about a

  pivot 31 parallel to the axis of the disc and attached to this disc

  than; on the plate 30 are mounted, on both sides of the

  pivot 31, on one side a first end 32 of the first resistor

  29, whose second end is fixed and stretched on a piece 34 secured to the disc, and, on the other side, a

  end 35 of the element 25 for transmitting the variation

  tensioning of the wire between the lever mechanism 24 and the

band 23.

247 1,439

  On the plate 30 is also mounted the end 28 of the strip 23, this fixing being located on the same side,

  that the attachment of the first spring 29 relative to the pivot.

  With the arrangement described above, the first spring 29, subjected to traction by the return force exerted on the end 33 which is fixed to the disk, causes a rotation of the plate 30 relative to the pivot 31 in the direction which, as can be seen in FIG. 2, tends to tightly tighten the band 23 around the brake drum and

  to exercise the maximum braking torque.

  The release of the brake depends on the action that the

  25 exerts on the plate 30 as a function of oscillations of the mechanism 24 for regulating the tension of the thread

  and which will be explained in detail below.

  Mechanism 24 is essentially based on the use of

  a lever whose axis of rotation is provided on a suitable support secured to the disk and whose branches are subjected, one to the action of the wire and the other to that of a

antagonistic spring.

  This spring has predetermined characteristics

  and calculated in such a way as to maintain the leverage in a

  fixed position as long as the wire does not exceed a pre-

  determined; beyond this occurs an oscillation of the lever with action on the transmission element 25 and suppression of the braking of the coil to reduce the value of the voltage

  wire to a substantially constant value.

  There are various characteristic solutions that can be adopted for a device for regulating the tension of the thread in accordance with the principle which has just been described and will be described in the following the preferred solution which comprises a lever 36 whose axis 37 is mounted in a rack

  38 which extends (see FIGS. 3, 4) in a direction substantially

  parallel to the axis of the spool and the arms 39, and 40 of the lever, the first arm supporting a pulley 41 whose axis of rotation is represented at 42 while the

  second is subject to the action of a second

  presented in Figure 2 and which performs the function already mentioned; the axis 37 of the lever is directed radially with respect to the axis of the coil (see FIGS. 3, 4) and the lever can therefore oscillate in planes orthogonal to this direction, and therefore in a very advantageous, without the influence of centrifugal forces which might otherwise be

  The second spring 43 is fixed by one end

  44 at a fixed point on the disk and at the other end.

  45, to another lever 46 (Figures 2, 3) whose pivot 47 is orthogonal to the disk and secured to this disk and whose arm 48 associated, at point 48 ', to the lever 36 via links ( not shown) which include an axis that can

  slide at the fork-shaped end of the arm 40 of the-

  leave 36 following the oscillations of the mechanism.

  The position of the fastening of the end 44 of the spring on the disk can be modified to vary the calibration of this spring and, for this purpose, means are provided.

  setting of a known type (not shown).

  On this second lever 46 is still mounted (Figure 2) the end 49 of the transmission member 25 interposed

  between the regulating device 24 and the belt brake 23.

  In one embodiment, this element 25 is constituted by a flexible element which transmits only

  traction forces, for example by a small metal cable

  or a nylon cord whose end 49 is fixed to the lever 46 opposite the spring 43 relative to

the position of the pivot 47.

  The use of a small wire rope to replace

  Another advantage of the invention in that, while being flexible, this small cable can take a curvature, for example on a pulley 25 'combined with the disk (see FIGS. which allows

  conveniently accommodate the springs within the free space

  mited by the small cable; in essence, with this cable, it is

  possible to arrange the two springs in positions

  very close to the center of rotation of the disc, which reduces the influence of the centrifugal force on the springs and, ultimately, brings the advantage of a correct braking of the coil.

  We will now describe, always in the form

  implementation of the regulating device 24, the

  course followed by the thread as it unwinds from the reel, before and after the passage around the pulley 41 which oscillates around

of pivot 37.

  At its exit from the spool, the yarn is first directed towards the return roller 50 (FIG.

  the small shaft It parallel to the axis of the coil, immediately

  diatement outside the cheek 51, then it passes around the pulley 41 of the lever 36, then it embraces the pulley 52 mounted crazy on the small shaft 11, in a manner independent of the roller 50 and, from there, it is deflected to the pulley 13 integral with the shaft and, by this pulley, sent inside the

the shaft towards the wiring point.

  In essence, wire 2, according to the preferred solution

  aforesaid, instead of simply passing first on a pulley secured to an arm unwinding and then on that which

  is attached to the tree, that is to say, instead of

  following a practically straight course, this wire follows a

  path consisting of a broken line, which

  Sieurs changes of direction with reduction of the maximum radius of rotation of the machine, obtained thanks to the presence of the return roller on which passes the wire directed towards the pulley 41, reduction which brings the possibility to increase

  the speed of the machine in that the dimensions of the machine

  Since these are reduced, there are fewer problems of equi-

  liberation and mechanical resistance and that we obtain, in par-

  particular, lower power absorption due to

aerodynamic resistances. -

  The other fundamental characteristic of the machine, relating to the means for disconnecting the reel from the disc, during the preparation of the reel activation during the relineing phase of new wire as well as during this phase, will now be explained. These means comprise a device 53 (FIGS. 2, 5) permanently combined with the disc 10, since it is rotated with the disc also during the

curing phase.

  The device 53 acts on one of the two ends of the first spring of the belt brake 23 and is based on the principle of keeping the spring energized

  during the curing phase and to obtain a report

  the ends of the spring and, consequently, a reduction of the deflection of this spring when the brake is loosened, which occurs when the machine is stopped. Preferably, and as indicated in the figures of the drawings, the device 53 acts on the second end 33 of the spring 29 and comprises an anchor 54 and a housing 55 formed on the disc and intended to receive the tip of the ankle when the latter is pushed

by a small spring 56.

  The ankle can in turn be placed at the

  a lever 57 whose axis of rotation 58 is mounted on the disc while the end 33 of the spring 29 is attached to the lever 57 opposite the peg; the device further comprises a handle 58 'with which the lever can be rotated clockwise as seen in FIG. 2 and thus unload the spring 29 during the

release of the belt brake 23.

  After the description of the basic characteristics

  of the invention, the corresponding phases of the func-

  which will be presented below will be clear in

  is lying. The presentation will begin with the situation illustrated in FIG. 1, in which the coils 7, 7 ', 8, 8' of the units of the machine 1 are working, the first being in phase.

  winding and the second in wiring phase.

  During the refolding phase of new wire,

  the disc 9 of the coil 7 is locked on the central support

  tral 6, for example by means of a pin, in an orientation

  suitably chosen to place the unwinder arm 11 in a low position and to avoid any interference with the dis-

positive wire guide 14.

  The coil 7 is rotated by the motor

  The invention is particularly adapted to refilling the new-wire spool provided by a spool or a feed barrel with a regulating action exerted on the forming turns by the dispenser 14 which moves the movable arm 21 and the pulley 22 in one direction and sometimes in the opposite direction, with a speed related to the speed of rotation of the coil 7 by a

predetermined law.

  The winding of new wire on the coil 7 'is

likewise.

  During the wiring, the disk 10 of the spool 8 is locked, for example by means of a pin, to a corresponding flange (not shown) of the shaft 5 which is rotated by the service shaft 15 and the transmission of movement for reloading new wire

is disengaged.

  The coil 8 is rotated around the shaft 5 by the traction exerted on the wire 2 by the means

* draw and lead 2 is guided in its passage from outside

  inside the shaft 5, first of all by its

  tact with the periphery of the return roller 50 (Figure 4), then on the pulley 41 of the control lever 36, thence on

  the pulley 52 provided at the end of the roll 50 and, finally,

  on the pulley 13 which rotates with the shaft 5.

  The core of the cable passes inside the shaft 5 together with the wire 2; this core is also subjected to the traction exerted by the drawing means and it is directed, from the unwinding frame 16, through the hollow shafts

  of all the units 4 of the machine, towards the point of

18-19.

  Always during this phase, the tension of the thread

  2 is compared, through the pulley 41 and the

  oscillator 36, to the reaction force of the spring 43 (Figure 2) and the tension which results from this comparison exerts, through the small metal cable 25, a moderating action on the clamping of the band 23 around the drum of brake of the reel, tightening which is itself insured

by the spring 29.

  When, for any reason, the machine stops, the disk 10 is braked in turn by a suitable brake, for example pneumatically controlled, and the coil 8

  tends to take the rotation advance relative to the disk.

  There is thus a release of the tension of the thread and the cancellation of the action that the tension of the thread exerts on the band 23 of the brake by means of the pulley 41 and the oscillating lever 36, in the direction tending to moderate the action of this band and, therefore, the brake,

  no longer subjected to the tensile force on the metal cable

  can intervene with the maximum torque available to him,

  which makes the connection between the disc 10 and the bobbin

  do 8 more and more efficient until their movement

relative is entirely canceled.

  The operation of the coil 8 'in the wiring phase occurs in the same way as indicated for

the coil 8.

  In the intermediate phases, the operations of reversal of the functions of the coils of the same unit occur as follows: When the machine is stopped, one releases the

  coil 7 of its connection with the motor for the re-

  new wire packing and makes the disc 9 secured to a corresponding flange of the shaft 5; then, the assembly is connected between the end of the wire of the coil 7 and

  the end of the wire of the coil previously exhausted from the

  contiguous tee closest to wiring point 19.

  The same procedure is used to prepare for the wiring phase the coils which have been re-wired in the previous phase in all

the machine.

  Then proceed to the operations that prepare

  the coil 8 now empty to the consecutive phase of

knitting of new thread.

  This operation is performed by acting on the handle 58 '(Figures 2.5) of the device 53, which makes the pin 54 out of its housing 55 formed in the disc 10 (Figure 5) and therefore stops the' traction exerted on the spring 29, thus causing the suppression of the

Braking the coil.

  Then, since the coil 8 is now free to rotate, the following phases are executed and, more specifically, firstly, the disc 10 is displaced angularly so that

  that the arm unwinding I1 is in conditions of non

  terference with the positions that the distributor 14 and the arm 21 for guiding the wire will take; then moving the movable arm 21 by a rotation of 1800,

  until the pulley 22 is aligned with the coil 8,

  Next, the disk 10 is locked on the support and the mechanical connection is established between the thread relining motor.

and the coil 8.

  Finally, the wire from the wire or the wire drawing coil is guided to pass around the pulley 22, from there around the coil 8 and begins.

the filling of the coil 8.

  In particular, the invention offers the advantage of comprising the braking elements of the coil, that is to say the two springs and the brake band, in a position extremely close to the disk without overflowing excessively in the axial direction. thus contributing, together with the other parts of the machine, to accommodate a large number of pairs of coils in a relatively limited space.
