Definitions

the present invention relates to a double winder with automatic transfer device in which two hooking discs each mounted coaxially with a spool shaft are arranged so as to be able to perform a recoil movement of limited angular amplitude, during the deposition of 'a winding, in order to form a reserve of wire with the initial strand of the winding.
the object of the present invention is to remedy these difficulties. For this, provision is made, according to the present invention, for a positive drive system for the discs. hanging. It is thus possible to temporarily modify the drive ratio of the attachment disc which normally rotates in synchronism with the spool shaft.
the double winder according to the present invention is characterized in that it comprises transmission devices with variable transmission ratio between each shaft and the corresponding attachment disc as well as means of command for temporarily varying the ratio of the transmission device which is associated with the spool shaft during winding.
the drawing shows the means for driving a spool designated by 1.
the winder however includes similar driving means arranged parallel to those shown, in order to drive a second spool on which the thread coming from a line of production will be deposited while the equipment visible in the drawing is stopped to carry out the change from a full reel to an empty reel.
the coil 1 of which the barrel 1a can be seen, a cheek lb and the hub lc is supported and driven by a shaft 2 which rests on bearings 3.
the shaft 2 is equipped at its end facing the coil 1 with a journal 4 movable axially so as to be able to be introduced into the hub lc.
This pin is of normal construction and will not be described in detail here.
the shaft 2 carries a pulley 5 which allows, thanks to a belt 6 cooperating with an electric drive motor to rotate the shaft 2 and the coil 1 at the desired speed.
this engine Before any transfer operation involving the shaft 2, this engine is started and gradually accelerates the shaft 2 up to a limit speed which is adjustable and corresponds to that of the shaft driving the parallel coil, so that the external surface of the barrel has a circumferential speed equal to the linear speed of the wire which is deposited on the other coil.
the automatic transfer mechanism that includes the double winder, includes in particular a hooking disc 7 on which is articulated a lever 8 carrying a jaw element 9 capable of cooperating with a jaw element 10 integral with the disc 7 in order to constitute a clamp wire hooking.
the disc 7 is mounted on a bearing 11.
it is linked by means of axial rods 12 distributed around its axis to a trough 13 also coaxial with the shaft 2 and whose outer part in the form of drum 13a surrounds the disc 7.
the chute 13- is itself integral with a pulley 14 and the assembly constituted by the pulley 14 and the chute 13 is mounted by means of two bearings 15 on a tubular piston 16.
This tubular piston 16 is itself carried by the base 17 of the machine which has a tubular extension 17a inside which the bearings 3 are mounted and whose outer surface is machined so as to guide the piston 16.
the base. 17 further carries a cylindrical member 18 which surrounds the left end of the piston 16 and forms the wall of a jack cylinder capable of being supplied with pressurized air by one or the other of two inlets 18a and 18b . It is understood that if pressurized air is injected through the inlet 18a, while the inlet 18b is connected to an air outlet, the piston 16 will move from left to right, carrying with it the bearings 15 and therefore the chute 13, as well as the pulley 14. The eyelets 13b of the chute 13 then slide on the rods 12. The reverse movement takes place when it is the inlet 18b which is connected to the air source under pressure.
the base 17 carries an elongated bearing body 19 equipped at its two ends with rolling bearings (not shown) and in which an auxiliary shaft 20 freely rotates, parallel to the shaft 2.
the shaft 20 has a notched part on which is engaged a sliding sleeve 21.
a pulley 22 mounted on the sleeve 21 drives, by means of a belt 23, the pulley 14 and therefore the chute 13 which, as we have seen previously is integral with the pulley 14.
the sliding sleeve 21 is mounted at the right end of the shaft 20 and immediately carries, next to the pulley 22, a ball bearing 24 whose external raceway is integral with a ring 25 which is fixed in a fork-shaped casing 26.
a rigid upright 27 connects the casing 26 to the tubular piston 16, so that, when the jack (16, 18) is actuated as seen above, the sliding sleeve 21 is driven via the ring 25 and the r oulement 24.
the pulley 22 therefore moves with the chute 13 in the axial direction.
the shaft 20 extends rearward and carries two drive mechanisms which both connect it to the drive shaft 2.
Each of these drive mechanisms has a driving pulley 27 or 29 which is keyed onto the shaft 2, a belt 30 or 31, a driven pulley 32 or 33 mounted idly on the shaft 20 and a disengageable electromagnetic coupling 34 or 35.
the pulleys 32 and 33 rest on ball bearings mounted on the shaft 20.
the electromagnetic couplings 34 and 35 each comprise, in a manner known per se, a driven or internal part which is constituted by a tubular extension coaxial with the shaft 20 and integral with the pulley 32 or 33 to which the coupling is associated.
This tubular extension cooperates with ferromagnetic elements which surround it and which can be excited by means of coils housed in the external part of the coupling.
the external parts of the two couplings are wedged directly on the shaft 20. They are provided with contact rings 34a, 34b or 35a, 35b which are connected (by means not shown) to an excitation circuit making it possible to put the electro - magnets under tension.
the arrangement described also includes a brake disc 36 which is mounted on the shaft 2 and held in place by a nut 37 and a lock nut 38.
This brake disc cooperates with shoes 39 shown in phantom in the drawing, which allows you to quickly block the winder if necessary.
the slowing down of the hook-carrying disc 7 is accompanied by a displacement of the chute 13, so that the wire designated by 40 comes to lodge inside the drum i3a of the chute 13 under the effect of the centrifugal force.
the transmission device with variable transmission ratio described above can also be used in a double winder in which the means provided for forming the reserve of thread operate differently from what is shown in the drawing.
the hooking disc 7 could not include the fingers 41 and instead of the chute 13, an anti-cut-off member extending between the hooking disc 7 and the coil could be provided.
the anti-cut-back member would perform a recoil movement of amplitude greater than that of the attachment disc so as to deploy the loop on a cylindrical surface coaxial with the coil, and keep it fixed throughout the winding.
the advantage of the device described is, as already mentioned, that it makes it possible to positively and precisely control the changes in the speed of rotation of the latching disc, and consequently to adjust the formation of the wire reserve.
this transmission device with variable transmission ratio can be constructed so as to be incorporated into a winding machine without the overall size thereof being increased to such an extent that this constitutes a drawback. for its operation.
