Definitions

  • the present invention refers to a device and process for preparing bobbins to feed to the automatic winder.
  • the prevailing yarn production technique consists of in a first spinning stage - typically ring spinning which produces bobbin yarn - followed by a second winding stage in which the yarn is unwound from its bobbin, cleaned of its defects and rewound onto a package, which contains a much greater yarn quantity and which corresponds to a considerable number of processed bobbins.
  • the winding processing is much faster than the spinning and thus a small quantity of winding units or stations, approximately several dozen, is capable of completing the production of a great number of yarn units, on the order of several thousands.
  • the transfer between the two processing sessions, of the bobbins full of yarn to the winder and their empty tubes to the spinning machine, can occur " en masse " or by means of movable bins, or - in the so-called "spin-winders” - directly and individually transferring the bobbins to the winder.
  • the bobbins arriving from the spinning machine have the terminal part of their yarn wound a specific number of turns around the bobbin pack or the base of its tube.
  • the prevailing technique of moving the bobbins and tubes is that which employs plate supports to be placed on conveyor belts or similar moving service members of the machine - for example rotating discs or belts - to individually bring said bobbins and tubes to and from the winding units.
  • said plates consist of a disc base which bears a central, vertical pin, on which the bobbin tube is inserted.
  • This pin allows maintaining the bobbin in upright position not only during the transport but also in the preparation and winding phases, in such a manner transferring and processing the bobbins practically without touching them. In fact only the plates are handled, without the bobbins being touched and scraped against, becoming dirtied or damaged in contact with the machine.
  • the present invention is aimed for the preparation of the bobbin, maintaining it upright on its plate.
  • the bobbin to be wound Before being fed to one of the winding stations which make up the automatic winder, the bobbin to be wound must be prepared, with a processing which is carried out in several steps.
  • the terminal part of the yarn on the bobbin must be freed from the base of the tube, or from the body of the bobbin, and unwound from the outer surface of the bobbin for a certain length.
  • the yarn is then cut to size and inserted in the upper end of its tube, from which the winding station - at the beginning of the winding of the new fed bobbin - can draw it, splice it with the skein end available on the package and restart the winding.
  • Such preparation is required both for the new bobbins coming from the spinning machine and for the not completely wound bobbins which - in the automatic winder - are generally recovered and recycled in order to use up the residual yarn still wound thereon.
  • the invention is described here with reference to a typical embodiment thereof in an automatic winder.
  • such winder type is composed of a plurality of winding stations or units aligned along the front of the machine and equipped with common service equipment for their management, among which the bobbin preparation unit is also comprised.
  • the sequence of the bobbin preparation operations is generally carried out with separated members and/or by transferring the bobbin to be prepared from one member to the other, with a complex procedure and with costly and bulky devices.
  • the present invention in its most general definition as bobbin preparation device, is defined in the first claim. Its preferred variants or embodiments are defined in the dependent claims 2-17.
  • the present invention in its definition as bobbin preparation process before its winding in a winding station, is defined in claim 18. Its preferred variants or embodiments are defined in the dependent claims 19-32.
  • the preparation cycle is carried out, for example, as follows.
  • the system is provided - for example - to always keep the processing position occupied with a bobbin ready for preparation or being prepared, and the waiting position always occupied by a bobbin to be prepared.
  • the cycle execution is governed by a governing unit (not indicated in the figures for the sake of simplicity) dedicated to the preparer device which receives the signals from the sensors present in the various parts composing the device and sequentially sends the commands for carrying out the various operations of the cycle.
  • a modified cycle is preferable and more reliable.
  • a step E* is inserted between step E and step F of the preceding cycle, such step E* employing the device 6A, which brings the skein end finder hook 6 against the bobbin 2.
  • the device 6A brings the skein end finder hook 6 towards the bobbin 2, it makes it slide along the generatrix line of the bobbin itself in order to lift or remove the skein end of the fastening 19, possibly pulling it free.
  • the roller 3 for rotating the bobbin 2 being processed is equipped with actuation in the two rotation directions, clockwise and anticlockwise.
  • Step E* is executed as follows. A first slow, descending movement of the hook 6 drawn near is carried out, and while the bobbin 2 is made to rotate in its winding direction, the hook finds the wound yarn, which surmounts it, freeing its skein end from the body of the bobbin 2. Or, if the skein end resists since it is held at the base of the tube, the hook pulls free the yarn. There is not yet need to activate the maximum suction with the mouth 5. At the end of such descent, the governing unit of the preparer controls the separation from the bobbin 2 and the ascension of the skein end finder hook 6.
  • step F the suction with the mouth 5 is activated to the maximum level, the yarn drawn from the bobbin enters the mouth 5 and affects the yarn presence sensor 7 in the mouth itself.
  • the additional step E* of picking up the skein end of the bobbin 2 with the skein end finder hook 6 of figure 1 or brush element 50 of figure 4 can be carried out in a conditional or unconditional manner.
  • the above-described base cycle is carried out up to the end of step G, and if at the end of said step G the sensor 7 signals the taking of the skein end with the mouth 5, the cycle continues normally and without said step E*.
  • the sensor 7 does not signal the "successful result" of the skein end being picked up only by suction
  • the bobbin preparation governing unit commands the interruption of the base cycle carried out up to step G, it makes it go back to step F and then commands the restarting of the cycle from step F, preceding such step however with the additional step E* for finding and separating the skein end with the mechanical hook device 6 or brush device 50.
  • the work cycle is programmed in the governing unit with the step E* already stably inserted before step F, avoiding cycle interruption after step G and avoiding returning back, after a skein end pick-up attempt only by suction with the mouth 5.
  • the rotation of the bobbin is carried out by also making the plate rotate with the roller 3: the plate transmits the rotary motion to the bobbin by friction.
  • the pin 21 of the plate 17 is necessarily made with a slightly smaller diameter than the inner diameter of the tube 23 of the bobbin 2, in order to allow the easy insertion and extraction of the bobbins respectively on and from the plate 17. The transmission of the rotary motion therefore occurs by the frontal friction between the circular base rim of the tube 23 and the upper annular surface of the collar 24 of the plate 17.
  • the improvement consists in the modification of the spindle centring system 4 of the bobbin 2 and its control 4A for approaching/moving away from the top of the tube 23 of the bobbin 2, as illustrated in figure 1 , so to centre the bobbin 2 on the plate 17 and to press it against its collar 24 in order to increase the transmittable torque to the desired level.
  • the centring spindle 30 of the bobbin is made with two separate and coaxial elements 31 and 41, equipped with means for approaching/moving away from the top of the tube 23 of the bobbin 2, until they are brought into abutment against the tip of the tube 23, said means also allowing reciprocal movements between such elements 31,41 in the axial direction.
  • the first element 31 has the form of a frustoconical funnel, with a side cleft 32 to direct towards the slit 5A in order to permit the entrance of the yarn suctioned by the mouth 5 and a narrow side opening 34, lateral and opposite to the cleft 32, in which the support arm of the second element 41 moves.
  • Such element 41 is moved inside the cavity and funnel which composes the first element 31.
  • the second element 41 is composed of an idle rotating spindle 42 mounted on watertight bearings 43 and supported by a support arm 44 which is raised and lowered with means 45, for example with a pneumatic cylinder system which in turn supports the outer funnel-shaped element 31, which is shown in figures 5A , B.
  • the idle spindle 42 is axially perforated with a duct 46 and supplied with compressed air by means of the connector 48, in order to act as injector for the insertion of the end of the cut-to-size yarn inside the tube 23, entirely analogous to that of the previously described Venturi 12.
  • Both the first element 31 and the second element 41 are equipped with lifting and lowering means, analogous to those previously indicated like 4A in the exemplifying embodiment of figure 1 .
  • Such means which in the following figures were shown as an example as a pneumatic piston 35 for the funnel-shaped element 31 and a pneumatic piston 45 for the idle spindle element 41.
  • the governing unit of the winder preparation station can be prearranged to adjust the supply pressure of the compressed air to such pneumatic pistons as a function of the processing work to be completed.
  • the spindle 30 thus formed by the two parts 31 and 41 accomplishes the functions of:
  • FIG 4 an embodiment of the device according to the invention is illustrated in which the skein end finder element is achieved with a brush 50 which is supported by a device 50A which supports the brush with an arm 51 capable of moving parallel to the axis of the bobbin 2, elastically pressing the skein end finder brush 50 against the bobbin 2.
  • the device 50A In order to pick up the skein end from the bobbin, the device 50A extends the arm 51 and brings the brush 50 against the bobbin, making it slide along the generatrix line of the bobbin itself in order to lift the skein end of the fastening 19.
  • the roller 3 is actuated in the bobbin unwinding direction.
  • the elastic support of the brush 50 by the arm 51 permits the brush itself to be moved along the line 52, consistent with the profile of the bobbin generatrix line, also faithfully following the terminal frustoconical parts.
  • the brush 50 can be made with normal natural or synthetic bristles, with small, thin cylinders of natural or synthetic rubber.
  • FIG 5A the bobbin 2 is shown in a preparation position with the spindle 30 still raised.
  • FIG 5B the extension of the piston 35 is shown with the descent of the funnel-shaped element 31 against the tip of the tube 23, in order to centre it and push the tube against the collar 24 of the plate.
  • the second spindle element 41 remains raised.
  • FIG 5C the retraction of the piston 45 is shown along with the descent of the spindle 41 with the partial insertion of its conical end in the tip of the tube 23. Due to the pressure exerted by the piston 45, the tube is pushed against the plate, in order to ensure that the rotation impressed on the plate is transmitted by frontal friction also to the bobbin 2. There follows the lifting of the funnel-shaped element 31, retracting the piston 35 and leaving only the spindle 41 to act as centring and thrust member.
  • the bobbin preparation steps E-H are carried out as described above, and in particular the rotation of the bobbin, with the possible step E* for removing the skein end by means of the skein end finder hook 6 of figure 1 or the skein end finder brush 50 of figure 4 , suctioning the skein end into the mouth 5, inserting the skein end of the yarn 16 into the scissors 15 and into the cleft 32 of the funnel-shaped element 31, as shown in the configuration of figure 3 and 5D .
  • the spindle 41 is raised by driving the piston 45 upward.
  • the piston 35 is extended and the funnel-shaped element 31 of the spindle 30 lowered so to seize the skein end of the yarn 16 between the lower frustoconical face 36 of the funnel 31 and the tip of the tube 23.
  • Figure 5G shows the cutting of the yarn 16 with the scissors and figure 5H shows the effect of the air blowing through the axial duct 46 in the spindle 42 of the element 41.
  • the cut skein end is inserted in the cavity of the tube 23: the quantity of yarn inserted in the tube is controlled, since the additional yarn winding by the bobbin is blocked by the engagement of the skein end between the funnel 31 and the tip of the tube 23.
  • Figure 5I shoes the final lifting of the funnel element 31 for the release of the bobbin 2 prepared for winding processing.
  • a further improvement of the present invention provides for increasing the friction between the surface of the upper rim of the collar 24 of the plate 17 and the bottom of the tube 23 of the bobbin 2.
  • Such friction increase is obtained as shown in figure 2 , by interposing an annular insert 60, for example fixing it on the collar 24, such insert 60 made of a material which offers a high friction coefficient, for example soft rubber.
  • an annular insert 60 for example fixing it on the collar 24, such insert 60 made of a material which offers a high friction coefficient, for example soft rubber.
  • one or both of such surfaces can be processed to make them rougher, or separately-prepared rough inserts 60 can be attached thereto.
  • the package bobbin preparation process and device of the present invention offers considerable advantages. Several of these benefits are worth a brief mention below.
  • the bobbin preparation device moreover allows adapting the preparation operations as a function of the bobbins to be worked, for example according to the type and count of the yarn, as well as the manner of its winding on bobbins in the preceding spinning, stably or conditionally inserting the supplementary step E* for finding the skein end and separating it from the mechanical hook or brush skein end finder element, adapting the reduced suction pressure value of the mouth 5, the rotation speed of the bobbin 2 - both in winding and in unwinding - with the roller 3, as well as the transmittable torque with said roller, the modality of drawing near and moving the skein end finder element, whether hook 6 or brush 50, the length of the skein end inserted inside the tube 23, and so on.
