    [0002] METHOD FOR TRANSFORMING A SPINNING MACHINE AND / OR THREAD TWISTING AND A YARNING MACHINE AND / OR THREADING MODIFIED ACCORDING TO SUCH METHOD
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The invention, as expressed in the statement of the present specification, refers to a method for transforming a machine for spinning and / or twisting of threads and to a machine for spinning and / or twisting of threads modified according to said method that provides, to the function for which it is intended, advantages and novelty characteristics, which are described in detail below and which represent an improved alternative for the current state of the art.
    [0007]
    [0008] The object of the present invention falls on a yarn spinning and / or twisting machine modified to carry out said spinning and / or twisting of the threads by making them rotate with multiple balloon regions for which it is distinguished by comprising an accessory that increases the height of the area occupied by the balloon region, that is, the separation distance between the guiding means in the yarn feeding zone and the twisting means of said yarn for winding it to the take-up reel, being Both the essential aspect of the present invention is a method for transforming the yarn spinning and / or twisting machine that performs spinning and / or twisting with a single balloon region into a machine that performs it with multiple balloon regions by incorporating to said machine an accessory that, without modifying other elements thereof, increases the height of the balloon region, that is, the separation distance between the guide means in the yarn feeding zone and the twisting means of said yarn for winding it to the collection.
    [0009]
    [0010] FIELD OF APPLICATION OF THE INVENTION
    [0011]
    [0012] The field of application of the present invention falls within the sector of the industry dedicated to the manufacture of yarn spinning and / or twisting machines.
    [0013]
    [0014] BACKGROUND OF THE INVENTION
    [0015]
    [0016] In the textile sector, and in particular in the sector of spinning and twisting of yarns, the use of continuous ring spinning machines, ring twisting machines, multiple twisting twisting machines, double twisting, vertical wiring, cabling twisting , etc. is known.
    [0017]
    [0018] All these machines, to provide torsion to the thread, are forced to rotate the thread at a distance from the center of rotation in order to save a space occupied by a part of the machine and this generates a figure of revolution that is called a "balloon." This balloon is defined by a zone or volume of revolution with a central axis of rotation, for example, with a conical volume.
    [0019]
    [0020] Previously, the trend for spinning and twisting machine manufacturers was to suppress or reduce the balloon by physically limiting it in order to avoid increasing the diameter of the balloon and reducing the height of the balloon as much as possible so that the stresses generated in the yarn for the twisting and / or spinning process were less and avoid possible damage to the yarn, which would affect its quality, breaks during the production process, so that the turning or angular speed was limited, negatively affecting productivity .
    [0021] The applicant himself, however, through his patent WO2017IB52009, discloses a yarn spinning and / or twisting procedure to avoid said drawback with multiple balloon regions instead of a single region; specifically a method in which a thread running between a thread feeding means (such as for example at least one bobbin) towards a thread collecting means, said thread collecting and / or winding means being linked to some means motors to rotate the thread collecting means at a predetermined speed, where a balloon region is generated at a point located between the feeding means and the collecting means by the presence of a twisting means, being distinguished specifically by the fact that that the twist speed value of the twisting means is such that the path followed by the twine between the feeding means and the collecting (or wound) means, by the actuation of the twisting means, generates a helical path with oscillating spiral diameters along the distance between the feeding means and the means for collecting and / or winding the thread, such that a body of revolution is created q It has at least one hyperboloid structure that forms at least two consecutive balloon regions, and can be carried out using structures that include between 2 and 20 balloon regions.
    [0022]
    [0023] According to said procedure, the torsion by means of multiple balloon regions compensates the working tension, in such a way that the tension produced by the torsion means is less than in traditional spinning and / or twisting processes, which, in turn, provides remarkable advantages.
    [0024]
    [0025] To achieve an increase in the number of balloon regions, and, consequently, hyperboloid structures, the procedure of the aforementioned document envisages increasing the height of the area that occupies the balloon, preferably, so that said height is at least twice the generator diameter of the balloon region.
    [0026]
    [0027] On the other hand, since this type of machines are high cost, what is usually done to apply said procedure is to modify the machine to increase the separation distance between the guide means, which are located at the top of the balloon region, under the yarn feeding zone, and the twisting means of said yarn for winding it to the take-up reel, in the lower part of said balloon region.
    [0028]
    [0029] The problem is that, until now, this modification, although it does not imply as much economic cost as manufacturing a new machine, is still very expensive and complex to carry out since, roughly, it is based on "cutting" the upper elements of the machine that encompasses the area of the guide means and wire feed and, through the incorporation of elements such as supports or others, for example profiles and uprights as a bridge, place them in a higher position that increases the aforementioned distance from the torsion means. It should be noted that, normally, these machines incorporate a plurality of parallel elements that spin and twist an equally plural number of threads at the same time.
    [0030]
    [0031] Well, the objective of the present invention is none other than the development of an improved modified machine to increase said height of the area that occupies the ball region by applying a method to carry out said modification, much simpler, easier to carry. carried out and, consequently, more economical and practical than using the system currently used.
    [0032] EXPLANATION OF THE INVENTION
    [0033]
    [0034] The method for transforming a yarn spinning and / or twisting machine and the modified yarn spinning and / or twisting machine according to said method that the invention proposes solve the exposed drawbacks and are configured as a remarkable novelty within its field of application , since in accordance with its implementation the aforementioned objectives are satisfactorily achieved, its characterizing details being conveniently included in the final claims that accompany the present description.
    [0035]
    [0036] More specifically, the machine that the invention proposes, as indicated above, is a yarn spinning and / or twisting machine that is modified to effect said spinning and / or twisting of the threads by making them rotate with multiple balloon regions for which, unlike the system used up to now of raising the set of machine elements that feed the thread and determine the means for guiding it, in order to increase the height of the area occupied by the balloon region, that is, the separation distance between the guiding means in the yarn feeding zone and the twisting means of said yarn for winding it to the take-up coil, is distinguished by simply having an additional guiding accessory that achieves the same effect, that is, increase the height of the area occupied by the balloon region by increasing the separation distance between the guide means in the wire feeding zone and the means s torsion of said thread for its winding to the take-up reel.
    [0037]
    [0038] Advantageously, said additional guiding accessory is an accessory that replaces the conventional wire guiding means and consists, for example, of a ring, clip or the like located at a certain distance above or below the wire feed rollers that increases said height of the balloon region area to allow twisting of the yarn by creating two or more balloon regions by being located at a point just below or even above said yarn feed rollers to increase the said separation distance between the guiding means in the yarn feeding zone and the twisting means of said yarn for winding it to the take-up reel, raising the position of the means.
    [0039]
    [0040] The additional accessory can be attached either to the yarn feed rollers or to any other fixed part of the yarn spinning and / or twisting machine. As an additional accessory, it can be attached to the machine in an agile way and without having to modify the structure of the spinning and / or twisting machine.
    [0041]
    [0042] Thus, in a first variant of embodiment, the said additional guiding accessory consists of a clip that is installed in the machine just at the exit of the thread of the rollers that constitute its feeding means, said clip being provided with one or more thread guide hooks guiding the thread at the upper end of the balloon region area, thereby increasing the height of said area so that there can be two or more balloon regions when twisting the thread.
    [0043]
    [0044] In a second variant of embodiment, the said additional guiding accessory consists of a mechanism for lifting the thread before twisting or wick, for example a group of rollers linked with a rolling belt (bands) on which the wick runs forming a loop to the exit of the feeding rollers, this group of rollers being with the rolling belt arranged in such a way that said loop raises the thread before twisting or wick above the point where it emerges from the feeding means, thus increasing the height of the balloon region area so that two or more balloon regions can exist when twisting the thread. Another example of a wire lifting mechanism before twisting or wick is by rollers.
    [0045]
    [0046] As indicated above, the invention refers to the method of transforming a yarn spinning and / or twisting machine to transform it into the previously described modified machine to effect said spinning and / or twisting of the threads by making them rotate with multiple regions of balloon by increasing the height of the area occupied by the balloon region, that is, by increasing the separation distance between the wire guide means and the wire twisting means, which comprises, at least , the following stages:
    [0047]
    [0048] - a first stage of eliminating the wire guide means located at a certain distance below the feeding means; and
    [0049] - a second step of incorporating an additional guiding accessory by placing it just after the wire feeding means, where said additional guiding accessory consists of the clip or a set of rollers with treadmill described in the preceding paragraphs.
    [0050]
    [0051] In this way it is possible to modify the yarn spinning and / or twisting machine by increasing the height of the area occupied by the balloon region so that it has two or more balloon regions in which the yarn is twisted, increasing the separation distance between the guiding means in the yarn feeding area and the twisting means of said yarn for its winding to the take-up reel, without it being necessary to lift the entire set of elements formed by the yarn guiding means and the feeding, which means a much simpler modification and less economic cost that, in addition, can perform much faster and, therefore, without affecting production.
    [0052]
    [0053] Finally, it is important to highlight that the variant embodiment will be preferred in which the additional guiding accessory is a mechanism for lifting the thread before twisting or wick, which comprises a group of rollers linked to the rolling belt on which the thread runs forming a loop at the exit of the feed rollers, causing the wick to rise above the point where it emerges from said feeding means, since in this option the wick, when moving together with the treadmill, does not suffer friction and , consequently, it does not deteriorate and, at the same time, the hairiness of the same is reduced, which is a negative characteristic for a good quality of the fabric that is going to be produced with the thread and is produced by the effect of rubbing it. with guiding elements such as rings or similar.
    [0054]
    [0055] The described method for transforming a yarn spinning and / or twisting machine and the yarn spinning and / or twisting machine modified according to said method therefore consist of innovations with characteristics hitherto unknown for the purpose for which they are intended, reasons that together with their practical utility, they provide them with sufficient foundation to obtain the exclusive privilege that is requested.
    [0056]

    [0069] PREFERRED EMBODIMENT OF THE INVENTION
    [0070]
    [0071] In view of the aforementioned figures, and in accordance with the numbering adopted, it can be seen in them, in addition to an example of a machine modified according to the prior art, two examples of non-limiting embodiment of the modified spinning and / or twisting machine according to the invention, which comprises the parts and elements indicated and described in detail below.
    [0072]
    [0073] Thus, in Figure 1 it is possible to observe, very schematically, the essential elements of a conventional and unmodified yarn spinning and / or twisting machine, that is, it has a single balloon region (a), and basically consisting of wire feeding means (1), preferably a set of standard rollers, conventional guiding means (3), which are located some distance below the feeding means ( 1), and delimit the upper end of said balloon region (a) superiorly, and a twisting (4) and winding (5) means of said thread (2) perpendicular to a take-up coil (6), preferably consisting of a turnbuckle that rotates around a ring, which determine the lower end of the balloon region (a) and which, in the representation of the figures, have been placed above the spindle that will form said coil (6) instead of of surrounding him, to procure a me better understanding of such elements.
    [0074]
    [0075] Referring to Figure 2, it can be seen how, according to the prior art, the method of modifying said machine to increase the height (h) of the zone of balloon regions (a), between the guide means (3) and the twisting means (4) and winding (5) in order to achieve that it has two or more balloon regions (a), consists of raising, such which, all the elements located in the upper part of said balloon region (a), that is, the guide means (3) and the wire feeding means (1) (2), moving them, without modifying their number or structure or configuration, to a superior position that agrees with the suitable position to achieve the necessary height (h) of separation between said guiding means (3) and the twisting (4) and winding (5) means so that it has the two or more searched balls (a).
    [0076]
    [0077] For its part, as seen in Figures 3 and 4-A, 4-B, in the machine of the invention and, according to the method proposed here, to carry out the modification to increase the height (h) of the region of regions of the balloon (a) to ensure that it has two or more regions of the balloon (a), provision is made to replace the conventional guiding means (3) with an additional guiding accessory (3 ') located at a point just after the wire feeding means (1) (2) either below or above them.
    [0078]
    [0079] More specifically, in figure 3 it is observed how said additional guiding accessory (3 '), in a first embodiment option, comprises a clip (30) that is installed in the machine just at the exit of the thread (2) of the rollers that constitute the feeding means (1) of the machine, said clip (30) being able to be provided with one or more thread guide hooks (31) that guide the thread (2) at the upper end of the region area balloon, thus increasing the height (h) of said area so that there can be two or more balloon regions (a) when twisting the thread.
    [0080]
    [0081] In Figures 4-A and 4-B, it can be seen how in a second embodiment variant, in fact a preferred variant, the additional guiding accessory (3 ') is constituted by a wire lifting mechanism before twisting or wicking preferably comprising a set of rollers (32) linked together with a conveyor belt (33) on the the wick (2) running in such a way that said thread (2) forms a loop just at the exit of the rollers that make up the feeding means (1) of the wick in which said set of rollers (32) is incorporated, and in such a way that said loop raises the wick (2) above the point where it emerges from said feeding means (1), thus increasing the height (h) of the area of the balloon region so that there can be two or more balloon regions (a) when twisting the thread.
    [0082]
    [0083] Preferably, the aforementioned set of rollers (32) with rolling belt (33) that make up the preferred variant of the additional guiding accessory (3 '), provides for the possibility of mobility of the relative position of the same in order to hold the wick (2) at one point or another, as appropriate, as seen in Figures 4-A and 4-B.
    [0084]
    [0085] Thus, with it, the method of the invention comprises, at least:
    [0086]
    [0087] - a first stage of elimination of the conventional guide means (3) of the wire (2) located at a certain distance below the feeding means (1); and
    [0088]
    [0089] - a second step of incorporating the additional guiding accessory (3 '), consisting of the clip (30) or a mechanism for lifting the thread before twisting or wick, this preferably comprising a set of rollers (32) with a conveyor belt (33), placing it just behind the wire feeding means (1), such that the distance between said additional guiding accessory (3 ') and the twisting (4) and winding means (5) of the wire ( 2) they determine an increase in the height (h) of the zone of balloon regions (a), between its upper and lower end, which allows to host two or more balloon regions (a).
    [0090] Once the nature of the present invention has been described, as well as the way to put it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the matter understands its scope and the advantages derived from it, stating that: within its essentiality, it may be carried out in other modes of implementation that differ in detail from those indicated by way of example, and which will also achieve the protection that is provided as long as its fundamental principle is not altered, changed or modified .
