Definitions
- the present invention relates in general to the treatment of yarn and is particularly concerned with the formation of windings of yarn intended to be subjected to a treatment such as steaming.
- a generally looser winding is formed.
- the latter is deposited on a transporter, such as a conveyor belt, which carries it into the treatment chamber.
- the winding of yarn is prepared by winding the yarn to be treated onto a winding core extending in a fixed direction of winding.
- Devices for forming windings of yarn, which include a winding core with an input end and an output end and with a rotary head for supplying the yarn which is able to wind the yarn into coils around the input end of the winding core.
- the winding advances on the core towards its output end due to entrainment by the transporter.
- the present invention relates to a winding device having the features set forth with pre-characterising portion of Claim 1, which is known e.a. from DE-A 2 847 291 and DE-A 2 939 716.
- the object of the present invention is providing such a device, which ensures, in all operating conditions, the regularity of the winding of the yarn onto the core and its gradual advancement towards the output end of the core itself.
- this object is achieved by virtue of a winding device having the further features set forth in Claim 1.
- the invention also relates to apparatus incorporating a winding device of the type specified above.
- apparatus usable for subjecting a yarn F to steaming is generally indicated 1.
- the yarn F is unwound from a supply reel or bobbin B 1 to be rewound onto a collecting reel or bobbin B 2 after treatment.
- the steaming is carried out by exposing the yarn to the action of the steam which collects in the treatment chamber 2 of the apparatus.
- an elongate winding of generally loose coils of yarn is formed from the yarn F supplied from the bobbin B i , by means of a device 3 whose structure will be better explained below with reference to Figures 3 and 4, so as to enable good penetration of the steam into the yarn.
- the winding of yarn formed by the device 3 is placed on a transporter device, for example a conveyor belt 4, which advances the winding from an inlet opening 5 to an outlet opening 6 provided in the walls of the chamber 2.
- a transporter device for example a conveyor belt 4 which advances the winding from an inlet opening 5 to an outlet opening 6 provided in the walls of the chamber 2.
- the upper pass of the conveyor 4 which receives the yarn is supported by rollers or pulleys arranged in such a way as to give the pass a profile in which an initial ascending section (in the direction of advance of the yarn), a central approximately horizontal section, and a final descending section can be distinguished.
- the winding of yarn is passed over a ve ntilator device 7 operated by a suction element 8, in order to cool the yarn before it is rewound onto the collecting reel or bobbin 8 2 .
- the apparatus 1 may in fact include one or more transporter devices 4 (in the example illustrated, ten) each of which advances a winding of yarn formed by a device of the type indicated 3 in Figures 3 and 4 into the chamber 2.
- a steam distribution duct 9 (connected to a source of steam, not illustrated in the drawings) including a main branch 10 and a secondary branch 12.
- the main branch 10 extends near (and preferably over) the upper wall or head 11 of the chamber 2, while the secondary duct 12 conveys the steam towards a grid or coil 13 which extends within the chamber 2 in its base region, which is completely open or at any rate provided with apertures, in a position below the transporters 4.
- the steaming chamber 2 is surrounded by an outer casing 14 of thermally insulating material.
- the steam supplied by the main duct 10 emerges through holes 15 provided in the duct and diffuses into the space between the upper wall 11 of the chamber 2 and the casing 14 of insulating material, heating the chamber 2 from its upper wall 11.
- the steam issuing from the main duct 10 is propagated downwardly inside the casing 14 and enters the steaming chamber 2 from the bottom.
- the vapour from the duct 10 thus penetrates the chamber 2 from its (open or at any rate apertured) base region where the coil 13 is situated so as to be able to give up heat to the steam supplied to the chamber 2, to prevent the temperature of this steam falling below predetermined values.
- the upper wall 11 Since the chamber 2 is heated from its top wall 11, using steam which is only subsequently introduced into the chamber 2 itself, the upper wall 11 is certain to remain at a temperature which is even a little higher than the temperature in the chamber 2. In this way, condensation of the steam on the wall 11 and consequent dripping of any condensate formed onto the yarn F which is being treated is completely avoided.
- a motor for example an electric motor, is indicated 16 and is provided with a shaft 17 which is traversed by a longitudinal cavity 18 at least in its portion extending within the motor 16 itself.
- a screw 19 including a core 20 and at least one thread 21 is mounted on the free end of the shaft 17, that is, the end opposite the body of the motor 16.
- a rotary head, indicated 22, has a generally bell- shaped configuration with an apex part rigidly keyed to the shaft 17 and a circular end edge 22a extending in a plane perpendicular to the axis of the shaft 17, in substantial alignment with the free end of the shaft 17.
- the bell 22 is traversed by a cavity 23 which extends along one of the "generatrices" of the bell and is connected in the region of the angle 24 with the cavity 18 of the shaft 17.
- the cavity 23 has an opening 25 facing the screw 19.
- the cavity 18 and the cavity 23 together define a duct for feeding a yarn F towards the opening 25.
- the yarn F is introduced, usually by pneumatic means, into the cavity 18 from the rear of the motor 16, that is, the end opposite the bell 22.
- the yarn passes into the cavity 23 and from the latter towards the opening 25, advancing continuously through the cavities 18 and 23 due to the rotation of the bell 22 caused by the operation of the motor 16.
- Two lining sleeves of ceramic material are indicated 26 and have the function of preventing the yarn from wearing grooves in the material (usually metal) of the shaft 17 and the bell 22, in the regions of the angle 24 and the opening 25, as it advances rapidly (600-1000 m/min) within the cavities 18 and 23.
- a further cavity 23a which is completely identical to and symmetrical with the cavity 23 (baricentrically symmetrical) is provided in the head 22.
- the head 22 is prevented from becoming unbalanced and oscillating or vibrating during rotation.
- a fork element is generally indicated 27 and is arranged to act as a core for the winding of the yarn F.
- the fork element 27 is constituted by a base part 28 which is generally sleeve-shaped, and two arms or prongs 29 which extend from the sleeve 28.
- the sleeve 28 is fitted onto the shaft 17 in an intermediate position between the base part of the bell head 22 and the end on which the screw 19 is mounted, with the interposition of bearings 28a which allow the sleeve 28 and the fork 27 to rotate freely together relative to the shaft 17, that is, not to be forced to rotate when the shaft 17 rotates due to the operation of the motor 16.
- the two arms or prongs 29 of the fork 27 extend from the sleeve 28 away from the bell head 22.
- Each arm 29 has an upstream or input end 30a situated in correspondence with the free end of the bell 22a and the screw 19, and a respective free or output end 30b.
- the two arms 29 are located in symmetrical positions relative to the axis of the shaft 17, which coincides with the axis of symmetry and rotation of the screw 19.
- the yarn which emerges from the aperture 21 is wound onto the two arms 29 of the core 27, as better illustrated in the sectional view of Figure 4.
- the bell head 22 is in fact rotated by the shaft 17 of the motor, while the winding core 27 is kept in a fixed position (by means which will be better explained below).
- each coil S 1 , S 2 also rest on the core 20 of the screw 19 and are thus exposed to the entrainment action exerted by the thread 21, the sense of which is selected so as to cause the forced advance of the coils which are gradually formed on the core 27 from the input end 30a towards the free or output end 30b of the arms.
- the wheel or pulley 31 is preferably mounted on a support apparatus 32 ( Figure 1) which is kept resiliently (or at any rate so that its position can be varied) in contact with the lower face of the winding core 27.
- the fact that the core 27 is, so to speak, resting on the wheel or roller 31 ensures that the core remains securely in a fixed position and is not thus rotated by the shaft 17 due to friction.
- the fact that the position of the wheel or roller 31 is adjustable enables this position to be adapted precisely to the variations in diameter (count) of the yarn which is being wound.
- the arms 29 of the winding core 7 converge slightly. In this way, it is possible to allow for any shrinkage of the yarn which may occur immediately after the winding has been formed.
- the winding of yarn to be steamed is formed inside the steaming chamber. This may be achieved by inserting the device or winding head 3 within the inlet opening 5 of the steaming chamber 2, so that the winding of yarn F to be steamed is formed inside the chamber 2, not outside as in the solutions according to Figure 1.
- the winding of yarn is passed over the ventilation device 7 operated by the suction element 8, in order to cool the yarn before it is rewound onto the collection reel or bobbin B 2 .
- the heating of the chamber 2 and the diffusion of the steam within the chamber is effected through the steam distribution duct 9 with its main branch 10 which extends near the upper wall or head of the chamber 2, and its secondary duct 12 which conveys the steam towards the grating or coil 13 extending in the bottom of the steaming chamber.
- a shaped cover 60 is associated with the outlet opening 6 of the chamber 2 and extends like a roof above the outlet opening 6 towards the outside of the steaming chamber 2.
- the function of the cover 60 is to protect against the escape of steam from the steaming chamber.
- the return pass of the conveyor belt 4 extends beneath the steaming chamber 2 and re-enters the steaming chamber 2 through an opening 50 provided in the base wall of the chamber in the region immediately below the inlet opening 5 in which the winding device 3 is inserted.
- the device 3 is substantially constituted by a winding core 27 including two converging arms on which the yarn F is wound in coils due to the rotation of the head 22 driven by the hollow shaft 17 through which the yarn F, unwound from the reel or bobbin Bi, enters the device 3.
- the winding of yarn formed by the rotation of the head 22 is advanced along the arms of the winding core 27 by the screw 19 which is also driven by the shaft 17.
- the shaft 17 is driven by a motor 16 through a belt or chain transmission 16a.
- the motor 16 may thus be located in a position out of alignment with the shaft 17, so as to permit the free passage of the yarn towards the winding device.
- a further motor (geared motor) 40 arranged below the device 1 drives the conveyor 4 through a driving pulley 41.
