Definitions

  • the present invention relates to an automatic device capable of eliminating windings or lengths of yarn, either formed by discontinuous fibres, or by one or more continuous filament(s), by completely removing them from their winding or deposit seat, at the same time strictly avoiding that the fibres contituting the same yarn may be dispersed into the surrounding environment.
  • the present invention relates to a device operating on textile machines which either produce or process yarn which, during determined process steps, is wound as reserve turns on axialsymmetrical elements, from which it is sucked and removed, with the process being either running or discontinued.
  • a textile machine e.g., a ring spinning frame
  • the yarns under way of formation are collected over conical tubes, forming bobbins having characteristics of shape and of dimensions pre-established by the production process, standardized on the basis of the structural characteristics of the same textile machine.
  • the ring-bearing bar When the bobbin is complete, the ring-bearing bar will come to position itself, after the bobbin-end tying, to a sub-reeling position, in order to deposit some yarn windings onto the basis of the spindles, so to build up a reliable anchoring for the yarn which must subsequently restart the spinning process.
  • the above said step precedes the step of full bobbin replacement by the empty tube on the spindles of the ring spinning frame.
  • Such devices are driven manually, or passively by means of centralized motor means.
  • said devices act by approaching to the wound yarn turns cutting element sharpened according to different geometrical shapes, or suitably pointed, which, by interfering under contact pressure, scrape and remove the reserve from its winding seat.
  • vibrational phenomena can arise, which cause a noisy operation of the machine, in that the sound levels overlap to each other and are amplified, creating a health risk for the operators.
  • the purpose of the present invention is to propose a solution purposely destined to prevent such drawbacks from occurring.
  • the ring rail during the ring spinning, at the beginning of the doffing sequence for the replacement of the full bobbin with the empty tube, after carrying out, during its downwards motion, the bobbin tying, positions itself at the lower level for the purpose of forming some yarn turns at the basis of the spindles, creating a reserve capable of constituting a reliable and necessary anchoring for the yarn which must subsequently restart the spinning process.
  • Said lashes accelerate the opening of the yarn ends, with yarn debris being sent to randomly flutter through the air inside the spinning room, which worsen the general soiling of the machinery, with the possibility of such large dirt buildups to be formed as to cause difficulties in the regular motion of the rings.
  • the present Applicant was furthermore able to verify that, as a consequence of the friction energy dissipated between air-fluid and centrifuged yarn ends, and, not lastly, their interferences, a larger energy absorption is observed per unit spinning frame, energy absorption which does not perform any useful functions, but which is dissipated as heat, requiring a further consumption of frigories by the general air conditioning system.
  • the present invention consists in an automatic ferrule cleaning device, and in a process for carrying out such a cleaning, and, more particularly, in an automatic unit provided with means for the reserve yarn cutting, means for the suction of the end brought into contact with a yarn seizing element provided immediately downstream the suction port and with conveying means for collecting the fibres of said reserve windings extracted from their seat.
  • Said cleaning step is committed to the device of the present invention, prearranged for operating in correspondence of an individual spinning station, or embracing two or more adjacent spinning stations.
  • the device according to the invention can be advantageously accomplished, within the scope of its specific intended use, as a unit mounted on a carriage sliding along the front of the machine on per se known guides or tracks, by means of which it is automatically positioned in correspondence of the spinning spindles by suitable motor means.
  • the movable working device can hence service a plurality of spinning stations, along which it is displaceable to and/or on the other side of the operating fronts, and, for such a purpose, at the head end of the machine a reversal station may be provided, through which the carriage is brought, by sliding on guides or tracks, to the spinning points of the other front in correspondence of which it starts the steps of operative functioning.
  • the device can be prearranged to serve the operative fronts of a plurality of machines, and for such a purpose guides or tracks are provided, which are substantially "U"-shaped, or which may even surround completely the spinning frames, suitable to enable the operative carriage to run along each front of the spinning frame, and along the same spinning frames.
  • Said guides allow furthermore said carriage to rotate around the heads of the machines, or around the head of a machine towards the other machine head, as well as it to run along said fronts.
  • the movable working device is briefly indicated hereunder as the "movable cleaning unit", wherein the prearranged devices for cutting, sucking and removing the fibres are conveniently positioned on the frame of said carriage-mounted cleaning unit, subject to automatic intermitted indexing along the machine, to service a plurality of spinning stations.
  • Said indexing motion is obtained by conveniently using one of the known mechanisms which convert a continuous revolution motion into an intermittent rectilinear motion.
  • a further purpose of the invention is to provide a power takeoff derived from the indexing motor unit, which allows the axialsymmetrical body to revolve with the process being stopped.
  • the means for obtaining such a power takeoff are known, and they need not be described in greater detail.
  • the cleaning operation is carried out, under a coordinate cooperation, by the action of a cutting element, of a suction device and of a seizing-extracting element for seizing and extracting the yarn windings from axialsymmetrical elements.
  • the yarn cutting element for example a knife shaped like a razor-blade can be used, which intervenes with its cutting action on the yarn length which connects the reserve on the spindle with the yarn collected on the bobbin, interrupting the continuity between the two buildups.
  • the said cutting element can be positioned, e.g., stationary on the support of the cleaning unit, or, for the purpose of facilitating the cutting process, it can perform a to-­and-fro motion, or a swinging motion relatively to the spindle centre.
  • a sucking nozzle As the sucking apparatus, able to catch the yarn end, a sucking nozzle can be advantageously used, the port of which is constituted by a ring-shaped slot surrounding the spindle. Such a sucking nozzle results positioned, in its operating step, at a short distance from the revolving yarn reserve, so that the yarn end is sucked with the desired reliability and is dragged by the air stream into the suction duct, which is in communication with a vacuum generator.
  • Such a short distance is advantageously obtained by translating the suction duct, by means of a slide running to-and-fro on the carriage support, relatively to the spindle, by being so driven by a simple eccentric.
  • the lower end of the suction duct can be telescopically sliding inside a tubular shell; in this way, the suction duct can be made fixed on the carriage frame, while the sucking nozzle undergoes a telescopic extension.
  • the exhauster is covered, on its suction side, by means of a perforated diaphragm, in front of which a collection chamber is provided, for the purpose of intercepting and collecting the fibres and the intaken yarn ends, which can be periodically collected from the said chamber for fibrous material collection.
  • a rapidly revolving cylinder can be advantageously used, which is provided with needle-shaped protrusions partially occupying the suction duct.
  • One of the merits of the device of the invention consists in its fitness of installation both on the operative fronts of the pre-existing machines, and on the fronts of the machines under way of assemblage.
  • the device of the invention results furthermore of very small overall dimensions and weight.
  • Such advantageous characteristics of overall dimensions and of weight propose an advantageous variant, according to which each machine front, or each single machine is equipped with the the carriage-mounted unit lacking of the operating elements of motion, cutting and suction.
  • Another merit of the device resides in its prevailingly mechanical operation, in as much as, except the frame running drive unit, the extractor cylinder motor unit, and the electric fan, no electrical, electromechanical or electronic parts slaved to the device exist.
  • the present device consists hence in a cleaning unit suitable to automatically remove the yarn windings from axialsymmetrical elements of textile machines, characterized in that it comprises, in a cooperating and coordinated relation: - a cutting means, performing the cutting of the yarn along the length of said yarn which connects the reserve on the spindle with the yarn collected on the bobbin, interrupting the continuity between the two buildups; - sucking means capable of sucking the yarn end, deriving from the previous cutting action, and of dragging it into the air stream of the suction duct; - means for yarn extraction, by means of the fast unwinding of the whole reserve.
  • Said extractor cylinder 16 occupies a space inside the suction duct 17 in the nearby of the ring-shaped slot 18, as it results from Figures 4 and 5.
  • the extractor element can be constituted by a tape, suitably positioned, and suitably provided with surface protrusions, or by counter-­revolving cylindrical elements, or by similar elements capable of seizing the yarn free end and of unwinding the whole reserve 25, even if the cylinder equipped with needle-like protrusions 16 is preferred by the present Applicant; 12 is the motor means driving the extractor cylinder equipped with needle-like protrusions 16, which is driven to a rapid revolving motion by the driving pulley 7, the transmission belt 8 and the driven pulley 10 integral with the shaft 28 of the said extractor element; 32 is the slide which acts as the support for the motor means 12; the motor means 13 drives the eccentric 13, which obliges and coordinates the translation of the slide 32 for approaching and removing the suction nozzle 18 to/from the spindle through the driving pulley 36, the transmission belt
  • the contact bars 43 fastened onto the element 22 extend along the machine.
  • the contact bars 43 and the collector contacts 44 of the movable cleaning unit 3 are covered by the shield sheet 42;
  • the motor means 12 and 13 and the electrical fan 29 can be fed with electrical power as well, according to a possible variant, by a simple cable cooperating with a cable reeling unit 24, or the electrical power can be fed to them by any suitable system for movable contacts;
  • 4 is a base support-bracket of the device, which acts as the support plane for the motion-driving, cutting, suction operative elements, assembled to a box-shape, which is fastened by the operator onto said carriage-mounted support, which is kept stationary at a standby station.
  • the device can run, according to closed paths, along one or more machines, or it can perform a reciprocating movement along one or more machines; in such a latter case of reciprocating movement, a reversal joint, or an equivalent system shall be provided, which is capable of securing that the disc 30 reverses its revolving direction, each time that the device comes at its stroke end and must return back.
  • the system operates as follows.
  • the device 3 Under rest conditions, the device 3 is positioned along the track length prearranged for it to rest in standby status in correspondence of an end of the textile machine, e.g., a ring spinning frame, externally to the operating front of the spinning stations.
  • the motion-­supplying centres, and the corresponding working means are stationary.
  • the motor means When the use is required of the device along the machine front, either automatically, or on command by an operator, the motor means are actuated.
  • the suction is actuated by means of the electrical fan 28, which applies a vacuum to duct 17.
  • the extractor cylinder 16 is driven to rapidly revolve by means of the motor means 12.
  • the drive disc 30 starts intermittently indexing the device 3 by means of motor means 13.
  • the eccentric 31, driven by the motor means 13, ensures, by means of the movable slide 32, a rearwards position (see Figure 5) of the elements of suction, extraction and cutting, constituting a block integral with said slide 32, movable relatively to the support of the cleaning device 3 in a direction perpendicular to the translation trajectory along the machine front 5.
  • the intermittent kinematic linkage operating through the grooved disc 30 positions, after the translation step, the device 3 in frontal correspondence between the vertical axis of symmetry of the sucking port 18 and the axis of revolution of spindle 11, ans makes device 3 to remain stationary in that position for the necessary time for the whole cleaning operation.
  • the eccentric 31 in cooperation with the movable slide 32, secures initially the approaching to the spindle 11 of the suction, extraction and cutting elements and secures the permanence of said elements in said approached position (see Figure 4) for the necessary time for their cleaning action to be performed.
  • Action which starts at the time point at which the razor-blade-shaped cutting element 27 interferes with the taut yarn length 26 of connection of the reserve on spindle 11 with the yarn collected on bobbin 9, thus interrupting the continuity between the two buildups.
  • Said yarn length is constrained in its circumferential position by the upper grooved disc 45 and by the lower grooved disc 46, which form a single body with the spindle 11.
  • the cutting effect is generated by the cooperation of the rotation of the spindle 11, by the interference between the cutting element 27 and the yarn length 26 and by the circumferential constraint of the grooves of discs 45 and 46.
  • the cutting action on the taut yarn length 26 generates two free yarn ends.
  • the yarn end belonging to the reserve buildup 25 is immediately caught and conveyed into the suction duct 17, because of the continuous vacuum existing in correspondence of the ring-shaped port 18 surrounding the spindle at the level of the cylindrical seat 34.
  • the winding turns 25 become loosened contributing to and securing the contact of the intaken yarn end with the needle-like protrusions 19, provided along the circumferential surface of the seizing-­extracting element 16.
  • the air stream existing inside the suction duct 17, generated by the vacuum generated by the electrical fan 29 delivers the said thread lengths and the fibrous dust into the collecting chamber 39, accumulating them on the front face of the perforated diaphragm 20, which prevents them from being dispersed into the air of the surrounding room.
  • the eccentric 31, actuated by the motor means 31 secures, through the movable slide 32, the displacement into a rearwards position (see Figure 5) of the suction, extraction and cutting elements forming an integral block with said slide 32.
  • the suction continues, and so does the revolution motion of extracting element 16.
  • the device 3 progresses stepwise, i.e., is progresses by a length equal to the distance existing between two adjacent spindles, then it stops.
  • the eccentric 31, always under cooperation with the movable slide 32, secures the approaching to the spindle 11 of the suction, extraction and cutting elements.
  • the automatic cutting, extraction and cleaning cycle starts again, and is repeated on the new spinning spindle.
  • the carriage-mounted device translates and rotates along running ways 2, constituted by a track, or by similar guides, suitably provided within the scope of a factory automation program (see Figures 7a, 7b, 7d).
  • the path to be followed by the carriage-mounted device of the invention must be made compatible with the motion of other movable elements, such as travelling cleaning units, automatic doffing cars, car for yarn re-connecting, and the like.
  • ratios and dimensions of the operating elements may be varied; a suction duct may be provided, which is stationary, or telescopically movable, or swinging, of moving according to another motion pattern; shapes and dimensions may be varied of the suction port and of the cutting element; it is possible as well to provide a different system of control of the intermittent indexing and of the cooperating control of approachment and removal of the cutting element and of the suction element, so, e.g., in said cooperation, it is possible to use two coordinated motor units, instead of a single motor means 13; it is possible as well to couple, or to remove motor units for the purpose of advantageously coordinating the whole set of the various operating steps; and so forth.
