Definitions

  • the object of the present application is to register a machine and a process for unwinding and winding yarn at a speed greater than 1 m/s, controlling the tensions of the yarn produced in the unwinding and winding process and thereby preventing the yarn from breaking.
  • the field of application of the present invention is comprised in the sector of the textile industry of any type of natural or synthetic yarns or fibers, particularly delicate yarns such as glass fiber yarns.
  • Machines for unwinding and winding yarn are known in the textile sector.
  • furnace-melted glass is extruded into multiple filaments measuring a few micra in diameter which are grouped together forming a glass fiber yarn which is wound by means of special winders for this application on flexible paper-cardboard containers or tubes mostly with an internal diameter of 300 mm and a length of 300 mm, commonly referred to as "cakes".
  • Said primary glass fiber yarn is classified by yarn thickness or count according to the amount of grouped filaments and measured in units of thousands of meters per kilogram (metric number, Nm), or more commonly in grams per 1000 m of yarn (Tex) in the sector.
  • this primary container or "cake” with wound glass fiber from the furnace must be transformed into a secondary container with a bottle-shaped format in plastic spools, referred to as "bottles”.
  • Said machines make use of the operating principle of ring twisting to change the "cake” format into the "bottle” format, conferring a low degree of twist to the yarn at the same time, therefore said transformation or unwinding/winding of a "cake” into a “bottle” is performed by applying certain twists per meter on the yarn, mainly between 10 and 40 tpm, or twists per meter according to the needs that arise.
  • twisting machines are not capable of transforming or unwinding/winding with a twist of 0 tpm, i.e., with the yarn keeping the fibers parallel, and therefore cannot be used to supply the industry that requires untwisted glass fiber yarn for certain applications.
  • the yarn tension experiences sudden changes in tension during the unwinding and winding process.
  • the change in yarn tension is caused by the relative position of the yarn output point with respect to the spool delivering the yarn or by the relative position of the yarn input point with respect to the spool collecting the yarn.
  • the twisting machines regulate the yarn tension basically through the traveler, and apply on the yarn a sufficiently regular tension that is within acceptable tension margins during the entire process.
  • untwisted glass fiber yarn in the "bottle” format constitutes a need that is increasingly in demand by certain consumers, there is no machine today which transforms a glass fiber "cake” into a “bottle", with the fibers being parallel, i.e., without twisting, and at a certain speed or productivity that makes said transformation cost-effective without altering or causing a deterioration of yarn quality.
  • the machine and process for unwinding and winding yarn without twisting and at a speed greater than 1 m/s object of the invention is not only useful for glass fiber yarn, but also for any type of natural or synthetic textile fibers or yarns.
  • the device proposed by the invention amounts to a novelty within its field of application, the characterizing details that set it apart being duly recorded in the claims included at the end of the present specification.
  • Transforming the yarn means unwinding the yarn from a yarn delivery spool, for example a first spool or "cake", and, in line, winding the yarn on a yarn collection spool, for example in a second bottle format spool, through a swinging or beaming system, at a certain speed and yarn tension.
  • the first object of the patent relates to a machine for unwinding and winding yarn at a speed greater than 1 m/s and without twisting the yarn, said machine comprising
  • the torque limitation value (Zmax) is between 0.001 N*m and 0.15 N*m such that the yarn tension (Twork) is not greatly affected when there are unexpected changes in the slip velocity (Vslip).
  • the rotary torque limiting means between the motor and the yarn delivery means or the yarn collection means are part of the motor itself, such that the actual output shaft of the motor slips beyond a certain electrical torque value applied to the motor.
  • the motor torque limiting means are at least one bearing located between the shaft of the motor and the spool with a torque limitation value (Z) caused by the friction between the inner and outer rings of the bearing.
  • the motor torque limiting means are at least two bearings located between the shaft of the motor and the spool, said bearings having a specific axial preload with respect to one another.
  • the machine comprises control means for controlling the speed of the motors of the yarn delivery means and the yarn collection means, consequently the slip velocity (Vslip) and the yarn tension (Twork), such that it is possible to adapt the slip velocity (Vslip) to the different situations which cause an increased yarn tension (Twork) for the purpose of keeping said yarn tension below a maximum tension (tmax) and above a minimum tension (tmin).
  • control means for controlling the speed of the motors of the yarn delivery means and the yarn collection means, consequently the slip velocity (Vslip) and the yarn tension (Twork), such that it is possible to adapt the slip velocity (Vslip) to the different situations which cause an increased yarn tension (Twork) for the purpose of keeping said yarn tension below a maximum tension (tmax) and above a minimum tension (tmin).
  • the yarn tension depends on the geometry, i.e., on the beaming, of the yarn delivery means and the yarn collection means.
  • control means preferably comprise means for capturing the instantaneous unwinding and winding diameters of the yarn delivery spool and/or of the yarn collection spool.
  • the means for capturing the instantaneous unwinding and winding diameters of the yarn delivery spool and/or of the yarn collection spool are preferably distance sensors or a computer program which computes the instantaneous unwinding and winding diameters of the yarn delivery spools and/or of the yarn collection spool based on the initial geometry of the yarn delivery spool and based on the geometry of the yarn collection spool over the working time of the machine.
  • the equipment preferably comprises anti-vibration means for preventing yarn vibration caused by an increase in yarn tension (Twork) followed by a quick decrease in tension (Twork).
  • the anti-vibration means for preventing yarn vibration are mechanical means and can absorb the increase and/or decrease in yarn length between the yarn delivery means and the yarn collection means, keeping the yarn tension (Twork) between the programmed maximum tension (tmax) and the minimum tension (tmin).
  • the anti-vibration means comprise a free rotary guide roller coupled to the end of a flexible rod having a section between 1 mm2 and 40 mm2 fixed to the machine with a distance P of between 200 mm and 1500 mm and which allows it to bend at yarn tension between 2 and 200 cN and absorb a yarn length of 50 to 1500 mm of yarn and with a yarn tension path Tmax of 300 cN.
  • Another object of the patent relates to the method for unwinding and winding yarn at a speed greater than 1 m/s and without twisting, applicable with a machine like the ones described above, said method comprising a step in which by modifying the slip velocity (Vslip), for example when an increase or decrease in yarn tension (Twork) is envisaged, the yarn tension (Twork) can be regulated so as to keep said yarn tension (Twork) below a maximum tension (tmax) and above a minimum tension (tmin).
  • Vslip slip velocity
  • tmax maximum tension
  • tmin minimum tension
  • the modification of the slip velocity is automatically controlled by control means which, depending on variables, such as instantaneous unwinding and winding diameters of the yarn delivery spool and/or of the yarn collection spool and on the weight of the spools, decide on the slip velocity so as to keep the yarn tension (Twork) between the maximum tension (tmax) and the minimum tension (tmin).
  • the method for unwinding and winding yarn at a speed greater than 1 m/s and without twisting also comprises the following steps in this order.
  • the yarn delivery or unwinding means are motor operated, and consequently regulate the yarn unwinding speed (Vlin).
  • the machine comprises rotary torque limiting means between the motor and the yarn collection spool. This configuration of the machine can be seen in Figure 1 .
  • the yarn delivery means (23) are made up of the delivery spool (1) which is fixed to the rotary shaft (2) through fixing means such as a pneumatically-operated extensible/compressible system fixing the yarn delivery means, for example, a spool through the inside of the cardboard tube, and making them integral with the shaft (2).
  • fixing means such as a pneumatically-operated extensible/compressible system fixing the yarn delivery means, for example, a spool through the inside of the cardboard tube, and making them integral with the shaft (2).
  • the motor (4) which transmits rotational movement to the yarn delivery means with an angular velocity W1 revolutions per minute or rpm is coupled in the same shaft (2).
  • the yarn (5) from the delivery means of the spool (1) is being unwound continuously in a perpendicular direction with a varying instantaneous unwinding diameter (D1) as it is emptied and unwound through the conical areas of the sides of the yarn delivery means (1).
  • the yarn (5) goes through the anti-vibration system (10), such as the one illustrated in Figure 3 , which consists of the yarn passing through two free rolling guides (6) fixed to the frame of the machine and at least one free rolling guide (6') secured to the end of a flexible rod (11) having a section (S), preferably of between 1 and 40 mm 2, and fixed to the machine at a distance (P), which allows it to bend and absorb at least a total length (L1max.+L2Max.-L1min.-L2min) of 400 mm of yarn and with a yarn tension path Tmax of 300 cN through the bending of the rod caused by the yarn tension.
  • the anti-vibration system (10) such as the one illustrated in Figure 3 , which consists of the yarn passing through two free rolling guides (6) fixed to the frame of the machine and at least one free rolling guide (6') secured to the end of a flexible rod (11) having a section (S), preferably of between 1 and 40 mm 2, and fixed to the machine at a distance (P),
  • the configured tension Tmax will always be equal to or greater than the working tension Twork and will never be equal to or less than 0 cN because the yarn would not relax otherwise.
  • the anti-vibration system (10) can be combined in many different ways such as, for example, in a case in which no rolling guide (6) is directly fixed to the machine and all the rolling guides (6') are associated with flexible rods (11, 11'), each with the respective rod thereof having a section (S), preferably between 1 and 40 mm2, and with fixing distances P which can be different and preferably between 200 mm and 1500 mm.
  • the anti-vibration system (10) may comprise at least one rolling guide with a flexible rod in the system to enable absorbing the required amount of yarn.
  • the yarn leaves the anti-vibration system (10) and moves towards a swinging or beaming system (7), as seen in Figure 1 , where said yarn is guided by the free rolling guide (8) which rotates driven by the yarn (5) itself and has a linear swinging movement along the traverse of the yarn collection means or winding spool (9).
  • the yarn (5) leaving the rolling guide (8) of the swinging moves towards the winding system (22), as seen in Figure 1 , where it is wound on the yarn collection spool or winding spool (9) which is integral with the shaft (16') and with an instantaneous winding diameter D2 and is beamed or moved according to the sequence of movements of the swinging system (7) in order to obtain the shape of the desired beaming, for example a bottle shape.
  • the swinging system (7) can be operated by any linear drive means such as a motor with a yarned spindle (14) where a yarned nut (15) in the spindle attached to the rolling guide (8) moves in one linear direction or another depending on the speed and direction of rotation of the motor and an encoder E for knowing the position of the rolling guide (8) at all times and which, along the entire system, is managed and controlled by computing and function programming means preferably located in a PLC or programmable automaton.
  • linear drive means such as a motor with a yarned spindle (14) where a yarned nut (15) in the spindle attached to the rolling guide (8) moves in one linear direction or another depending on the speed and direction of rotation of the motor and an encoder E for knowing the position of the rolling guide (8) at all times and which, along the entire system, is managed and controlled by computing and function programming means preferably located in a PLC or programmable automaton.
  • the collection means (22) seen in Figure 1 comprises torque limiting means (12) fixed between the motor shaft (16) and the spool shaft (16') such that the collection spool (22) slips in a rotary manner when the angular velocity W2 of the motor (13) is greater than the angular velocity W2' of the collection spool (9).
  • the torque limitation value (Zmax) must be fixed between 0.001 and 0.15 N*m, and even more preferably it is 0.005 N*m.
  • the torque limitation value (Zmax) is selected depending on the tension (Twork) to be applied to the yarn in combination with the slip revolutions applied.
  • the slip velocity (Vslip) along with the torque limitation value which, in this preferred example, is set to 0.005 N*m, regulate the yarn tension (Twork).
  • the angular velocity of the collection spool (W2') is associated with the angular velocity of the delivery spool (W1), with the unwinding diameter D1, and with the instantaneous winding diameter D2, i.e., any change in the linear speed of the yarn (5) and in the diameters D2 and D1 of the winding spool (9) and unwinding spool (1) will cause a change in the angular velocity W2' of the winding spool (9).
  • the slip velocity (Vslip) when the torque limiter is located in the collection spool, the slip velocity (Vslip) must be positive in order to generate tension greater than 0 cN, i.e., the minimum tension (tmin), on the yarn (Twork) at all times. At a higher slip velocity, the tension applied on the yarn (Twork) will be greater, and in contrast, if the slip velocity (Vslip) is very small, the tension applied on the yarn (Twork) will be very small, keeping the torque limitation value (Zmax) fixed.
  • the torque limiter (12) is a mechanical element widely known in the state of the art, although in the case of the present invention, the need to set very small slip torque values of between 0.001 and 0.15 N*m means that a highly effective limiter for this application is at least one bearing in which the actual torque of the bearing is the one required for transmitting the movement from the inner ring to the outer ring or vice versa, i.e., it may be in values of 0.001 N*m.
  • At least one bearing of any type, i.e., ball, roller, friction, needle, axial bearings, etc. is an effective torque transmitter having a very small torque value within the range of 0.001 to 0.15 N*m, providing a solution in the present invention.
  • the means which collect the yarn (9) or collection spool is concentric to the shaft (16") through ball bearings (17 and 17'), each acting as torque limiters, which allow a specific torque (associated with limiters 17 and 17') to be transmitted between the axis 16" and the spool 9.
  • the spool is axially fixed by the limiting bushings (18 and 18').
  • the torque limiting means comprise at least two bearings (19 and 19') assembled on one and the same support (20) and limited of axial movement of the shaft (16") through the retaining bushings (18" and 18′′′).
  • the inner rings of the bearings (19 and 19') are preloaded by a force F having an axial component exerted by the spring (21) on the balls of said bearings (19 and 19'), causing the force F to cause the torque that they transmit as a whole to be greater than the sum of torques that they transmit individually without the preload F.
  • the two bearings which, individually without any preload F, transmit a total torque of, for example, 0.01 N*m, when being subjected to preload F
  • the transmission torque or limiting torque of the system can increase such that, depending on the preload value F, values of 0.1 N*m or even higher can be achieved in a controlled manner, covering all the torque limitation possibilities claimed in the present invention.
