Description

Method for switching yarn spinning and/or twisting machine, and modified yarn spinning and/or twisting machine by the method

Purpose of the invention

As stated in the language of this descriptive report, the present invention relates to a method for switching yarn spinning and/or twisting machines, and modified yarn spinning and/or according to the method For the twisting machine, the method provides novel advantages and characteristics for the functions that the present invention intends to achieve. These advantages and characteristics will be described in detail below and represent improved alternatives to the current state of the art.

The purpose of the present invention corresponds to a yarn spinning and/or twisting machine modified to perform spinning and/or twisting of yarns by rotating the yarns with a plurality of ball regions, the difference being that it includes a Accessory, the height of the area occupied by the ball area, in other words, the separation distance between the guide member in the area where the yarn enters and the member that twists the yarn for winding the yarn to the pickup spool The basic aspect of the present invention is therefore a method for spinning a yarn and/or twisting a yarn using a single ball area by incorporating an accessory into the machine And/or the twisting machine is converted into a machine that uses multiple ball areas to perform spinning and/or twisting. Without modifying other components of the machine, the accessory allows the height of the ball area, in other words, where the yarn enters. The separation distance between the guide member in the region of the guide member and the member of the twisted yarn to be wound onto the collection spool is increased.

Field of application of the invention

The field of application of the present invention is framed within the industry dedicated to the manufacture of yarn spinning and/or twisting machines.

In the textile industry, and especially in the spinning and twisting section, the use of continuous ring spinning machines, ring twisting machines, multiple twisting machines, double twisting machines, vertical connection, twisting twisting machines, etc. known.

In order to twist the yarn, all these machines are forced to rotate the yarn at a distance from the center of rotation, so as to save space occupied by a part of the machine, and this produces a figure called "balls" around the rotation. This sphere is defined by a zone or volume of revolution about the central axis of rotation, for example about a conical volume.

Previously, the trend of manufacturers of spinning machines and twisting machines was to suppress or reduce the ball by physically restricting the ball to prevent the diameter of the ball from increasing and reducing as much as possible The height of the ball makes the tension used in the yarn used in the twisting and/or spinning process less, and avoids possible damage to the yarn that affects the quality of the yarn and breaks during the production process, so The rotation speed or angular speed is limited, which has a negative effect on productivity.

However, the applicant himself disclosed a procedure of yarn spinning and/or twisting through his patent WO2017IB52009 to use multiple ball regions instead of a single region to avoid this inconvenience; in particular, a process in which the yarn is made from one yarn The thread feeding medium (such as at least one spool) extends to a yarn picking medium, wherein the yarn picking and/or winding medium is coupled to the motor member to rotate the yarn picking medium at a predetermined speed, and one of the ball areas is twisted The presence of the thread member occurs at a point between the feed medium and the pickup medium, and the twist member is distinguished in particular by the fact that the value of the rotational speed of the yarn twist member makes the yarn driven by the twist member The trajectory followed between the feed medium and the pickup (or winding) medium generates a spiral trajectory with an oscillating spiral diameter along the distance between the feed medium and the yarn collecting and/or winding member In order to create a revolving body with at least one hyperboloid structure forming at least two continuous ball regions, it can be implemented by means of a structure containing between 2 and 20 ball regions.

According to this procedure, the working tension is compensated by the twisting of the plurality of ball regions, so that the tension generated by the twisting member is lower than the tension in the conventional spinning and/or twisting process, which instead provides significant advantages.

In order to increase the number of ball areas and therefore the hyperboloid structure, the procedure of the previous document envisages increasing the height of the area occupied by the ball area, preferably such that the height is at least twice the resulting diameter of the ball area.

On the other hand, since these types of machines are expensive, all that is usually needed to apply this procedure is to modify the machine to increase the guide member and the upper portion of the ball area under the yarn feed area. The separation distance between the members for twisting the yarn in the lower part of this area of the ball for winding the yarn to the pickup spool.

The problem is that up to now, even though this modification does not involve as much economical cost as building a new machine, the realization of this modification is still costly and complicated because the modification is mainly based on "cutting" the covering yarn of the machine The upper element of the area of the wire guide member and the feed member, and the element via the incorporation of other elements such as supports or other elements such as dilators and bridge posts), so that these upper elements are in the aforementioned increase relative to the torsion member The higher the distance. It should be noted that these machines usually have a plurality of parallel elements that are simultaneously spun and a plurality of yarns with equal number of twists.

The purpose of the present invention is to develop an improved machine modified to increase the height of the area occupied by the ball area by applying a method. The method for realizing the modification is simpler and more convenient than the system currently used. Easy to implement, and therefore more economical and practical.
