Definitions

  • the present invention relates to improvements to devices for processing textile threads or yarns. More specifically, the present invention relates to a device for the distributing yarn or thread on a winding spool or reel, of the type comprising: a thread guide provided with an alternate movement for distribution of the yarn, an actuator member to provide motion to the thread guide, and a mechanical transmission between the actuator member and the thread guide.
  • the invention also relates to a machine or appliance for producing spools or reels which utilizes a distribution device of the aforesaid type.
  • spools or reels of yarn to be used, for example, to feed knitting or hosiery machines, or other textile machines, appliances are used in which a winding tube is made to rotate and yarn is wound therearound in turns to form the finished spool or reel.
  • a device that distributes the thread or yarn on the spool according to a suitable law, based on the characteristics of the spool or reel to be obtained.
  • the distributing device of the yarn has a thread guide provided with alternate movement transmitted by means of suitable kinematic means by an actuator member, synchronized with the movement of the tube or spool in order to obtain specific winding parameters of the yarn, such as wind ratio, pitch of the turns and variations of said parameters to guarantee that reel formation is suitable for the subsequent processing processes.
  • EP-A-403927 ( US-A-5082193 ) describes a device for distributing yarn on a spool being wound, in which the thread guide is supported at the end of a rod provided with an alternate translational movement. Movement of the rod is imparted by a wheel controlled by a motor with electronic control.
  • the thread guide is supported by a flexible member running around two or more pulleys, one of which is motorized.
  • the alternate movement of the motorized pulley obtained by an electric motor with electronic control, imparts a corresponding alternate movement to the thread guide.
  • Examples of yarn distribution devices based on this technology are described in EP-A-0950627 ; EP-A-829443 , EP-A-1125878 , EP-A-1209114 , EP-A-1219559 , EP-A-1318097 , EP-A-1319622 , EP-A-1520825 , EP-A-1520826 , EP-A-1520827 , EP-A-1048601 , EP-A-453622 , EP-A-1048601 , EP-A-311827 and EP-A-1044917 .
  • the object of the present invention is to produce a device of the type described with which results can be obtained in terms of control precision and/or speed and/or reduction in stresses, exceeding those of conventional devices.
  • the invention is based on the idea of providing a slider which is part of the mechanical transmission between the actuator member and the thread guide, which is operated with alternate motion by means of said actuator, combined with a motion multiplier to which the thread guide is attached.
  • the motion of the thread guide is multiplied with respect to the normal motion of the slider operated by the actuator member.
  • the speed of the thread guide with respect to the speed of the slider can thus be multiplied by a suitable factor, for example 2 or 3, without having to increase the operating speed of the actuator member, typically the electric motor with electronic control.
  • a device for distributing yarn on a spool, comprising: a thread guide provided with an alternate movement, an actuator member to supply motion to said thread guide, and a mechanical transmission between said actuator member and said thread guide; characterized in that the mechanical transmission includes a slider operated with alternate motion by means of said actuator member, which supports idle guide pulleys for a flexible element to which said thread guide is attached, said flexible member being in turn attached to a fixed structure with respect to said slider.
  • the multiplication factor can be equal to 2 or greater, as will be illustrated hereunder with reference to some examples of embodiments. This allows double speeds of the thread guide to be obtained with the same speed of the actuator motor.
  • the thread guide is arranged along a rectilinear portion of the flexible member extending between the two guide pulleys, the axes of which are aligned longitudinally along the direction of movement of the slider.
  • the slider supports two guide pulleys.
  • the flexible member can be fixed to a point of the fixed structure, or can run around idle pulleys mounted with a fixed axis on the load-bearing structure.
  • At least two guide pulleys supported idle by the slider and at least two guide pulleys supported idle by the fixed structure are provided, said flexible member running around said pulleys supported by the slider and around said pulleys supported by the fixed structure.
  • the slider can be made to move by various kinematic mechanisms.
  • a rack and pinion mechanism can be provided, where the rack is integral with the slider.
  • a friction wheel which cooperates with a friction surface integral with the slider can be provided.
  • said rack can be produced on a rod forming the slider or a part thereof, sliding in a guide integral with said fixed structure.
  • drive systems with a cam and tappet, a cam and rocker arm, a flexible member and guide pulleys, or other mechanisms, which provide the slider with alternate movement, can be used.
  • the invention provides a device for distributing yarn on a spool, comprising: a thread guide provided with an alternate movement; an actuator member to supply the motion to said thread guide; and a mechanical transmission between said actuator member and said thread guide; wherein said mechanical transmission comprises a slider operated with alternate motion by means of said actuator member and a motion multiplier, to which said thread guide is attached.
  • the invention also relates to an appliance for winding reels or spools of yarn, comprising a rotation system for the spool or reel and a device for distributing yarn on said spool or reel, produced as described above and as will be better illustrated hereunder with reference to some examples of embodiment.
  • Figure 1 schematically shows an appliance, indicated as a whole with 1, for producing spools or reels R of yarn F coming from a suitable processing machine, not shown.
  • movement of the thread guide is multiplied by a factor of 2 with respect to the speed of the actuator.
  • the spool R is formed around a winding tube supported by arms 5 above a winding roller 7.
  • the roller 7 rotates in the direction indicated by the arrow in the figure and is in contact with the cylindrical or conical surface of the spool R being formed.
  • This can have any suitable shape, e.g. cylindrical, conical, biconical or the like, as a function of the use for which it is intended.
  • the motorized roller 7 transmits motion to the spool being formed through friction.
  • movement of the spool is imparted by a motor which can be mounted on the spool arm and coaxial with the reel or driven by a motor mounted with fixed axis by means of a belt or the like to a pulley supported on the spool arm and coaxial with said spool.
  • the yarn F is fed and distributed in helical turns on the spool R by means of a device 9, shown and described in detail hereunder with particular reference to Figures 2 to 6.
  • the device 9 includes a thread guide 11 (for example made of a ceramic material) supported by a bracket 13 provided with an alternate movement in a direction orthogonal to the plane in Figure 1, and consequently parallel to the axis of the spool R being formed.
  • the bracket 13 with the thread guide 11 is attached to a branch of a flexible element 15, running around two pulleys 17A, 17B supported idle around respective axes supported by a substantially rectilinear (in the drawing) slider 19.
  • the absolute position of the thread guide is determined by a sensor 16 ( Figure 3) and a corresponding feeler 18 integral with the pinion or a notch therein, or also by an electronic control device, already available on the market, provided with its own set-point.
  • These references correspond to a position, for example although not exclusively mean, on the tube from which to implement the count of movement of the thread guide to allow tubes of different lengths to be mounted without mechanical adjustments.
  • the slider 19 In the position in Figure 3, the slider 19 is in the intermediate point of its excursion and the thread guide 11 supported by the bracket 13 is on the mean plane between the two pulleys 17A, 17B.
  • the branch of the flexible element 15 opposite the branch on which the bracket 13 is fixed is fastened in a fixed point 21 to the load-bearing structure, indicated as a whole with 23.
  • the flexible element 15 is a continuous element, i.e. endless. Nonetheless, this is not necessary, as the ends of the flexible element could also be separated from each other and attached in appropriate points of the fixed structure 23, with an arrangement suitable to allow movement of the thread guide 11 as illustrated hereunder.
  • the slider 19 is composed of two portions 19A and 19B attached to each other by means of screws 25 which also attach the pulleys 17A, 17B to said slider.
  • the portion 19A of the slider forms a seat inside which the upper branch of the flexible element 15 is housed and in which the lower part of the bracket 13, with which the thread guide 11 is attached to the flexible element 15, slides.
  • the portion 19B of the slider is, on the other hand, composed of a rack which meshes with a pinion 27 keyed onto the output shaft 29 of an electric motor 31 with electronic control. Rotation in alternate directions of the motor 31 consequently causes an alternate translational movement of the slider 19. During this movement the slider is guided by the portions 19A, 19B inside a guide 33 produced in the fixed structure 23.
  • the slider 19 is in its intermediate position between two end positions (shown in Figures 7 and 8) that said slider can take during operation through alternate rotation of the electric motor 31 forming the actuator member of the device.
  • the thread guide 11 is on the mean plane of the slider 19, equidistant from the pulleys 17A and 17B. Conversely, in Figure 7 the slider 19 is moved to the left (observing the figure) performing a movement C with respect to the mean position. A double movement, equal to 2C, of the thread guide 11 corresponds to this movement. In Figure 8 the slider 19 is moved to the right to a second end position thereof, again performing a movement C with respect to the intermediate position in Figure 3, while the thread guide has performed (again with respect to the intermediate position) a movement 2C.
  • Figure 9 shows a solution in which the slider 19 is attached to a flexible member 41 guided around two pulleys 43 and 45, the axes of which are carried by the fixed load bearing structure 23.
  • One of the two pulleys (for example the pulley 43) is motorized, that is, it can, for example, be keyed directly onto the output shaft of an actuator, composed for example of the electric motor 31.
  • 51 indicates a motor shaft which can be made to rotate by an actuator, for example an electric motor 31.
  • the shaft 51 supplies rotational motion to a grooved cam 53, with 53A indicating the groove inside which a feeler 55 engages.
  • the feeler 55 is integral with the slider, again indicated with 19, which consequently moves with alternate motion according to the double arrow f19 guided on a fixed structure, again indicated with 23.
  • the slider 19 supports two idle pulleys 17A, 17B, running around which is the flexible element 15, integral with which, by means of the bracket 13, is the thread guide 15 in which the thread F is guided to be wound on the spool R.
  • kinematic mechanisms can be used instead of a grooved cam, such as a simple cylindrical cam combined with a tappet with rocker arm or the like.
  • the device according to the invention can be used in various existing appliances or machines, adapting the device to the specific motion transmission mechanism of each machine or appliance in which the device is incorporated.
  • the thread guide 11 is provided with a movement multiplied by a factor of 2 with respect to the movement of the slider 19.
  • the same inventive concept can be further developed to allow multiplication ratios greater than 2, to the detriment of the constructional simplicity of the device.
  • Figures 11 and 12 show a front view analogous to the one in Figure 3 of the device with the slider in an intermediate position and in one of the end positions it can take.
  • the same numbers indicate the same or equivalent parts to those in the previous embodiments.
  • the flexible element 15 is not fastened to the structure 23 in a fixed point, but is attached to said structure due to the fact that it runs around pulleys 61A, 61 B supported idle on the fixed structure 23, and around the pulleys 17A, 17B supported idle by the slider 19 and translating therewith.
  • the flexible element 15 has two ends 15A, 15B fixed at the level of the axes of rotation of the pulleys with movable axis 17A, 17B supported by the slider 19. In practice, the flexible member 15 runs twice around each of the four pulleys 17A, 17B, 61A, 61B.
  • the alternate movement can be imparted to the slider 19 by means of kinematic mechanisms differing from the rack and pinion mechanism 27, 19B.
  • kinematic mechanisms differing from the rack and pinion mechanism 27, 19B.
  • systems with grooved cams ( Figure 10) or a belt transmission ( Figure 9) or the like can be used.
