Definitions

  • the present invention refers to an individual suction device for the winding units that make up the automatic winder.
  • winders in fact consist of a plurality of winding units aligned along the front of the machine and equipped with common control and service apparatuses.
  • the winding unit is illustrated in its essential components in figure 1 , omitting the components of secondary importance for the technical solution that constitutes the present invention.
  • the supply spool 1 is unwound pulling out the thread 2.
  • the thread 2 passes by the unwinding group that comprises organs for guiding the thread 3, the sensor 4 for detecting the presence of the thread and the thread tensioning device 5.
  • Said thread tensioning device generally consists of a pair of washers facing one another and pressing the unwinding thread 2 between them with a regulated and controlled pressure, said thread running between them at high winding speed take up.
  • the device 6 for piecing the yarn ends commonly called splicer, to which the interrupted yarn ends of the thread that needs to be connected by suction pipes 9 and 10 are taken, when the thread is interrupted due to breaking or due to a cut of the yarn clearer 11 that is immediately below the splicer.
  • the wound thread is collected in the package 12, which is set in rotation by the winding drum 13, on which it rests supported with the package support arm 14, at a predetermined and substantially constant linear winding speed take up.
  • the package 12 in rotation draws the thread 2, unwinding it at a high winding speed take up from the spool 1 kept still on a positioning pin 15.
  • the spool suction pipe 9 on the side of the spool can make the angular movement ⁇ that brings the suction hood of the suction pipe itself first to capture the yarn end of the thread 2 from the unwinding group 3, to lift according to the rotation ⁇ , bringing the yarn end to the splicer 6.
  • the package suction pipe 10 on the side of the package on the other hand can make the angular movement ⁇ that brings the suction hood of the package suction pipe itself first to capture the yarn end of the thread 2 from the package 12, to lower with the rotation ⁇ , until it brings the yarn end on the side of the package to the splicer 6.
  • the suction pipes 9 and 10 are connected to a device for generating depression that, during restoration interventions of the thread 2 continuity between the spool 1 and the package 12, provides for the depression necessary to capture and handle the yarn ends on the side of the spool and on the side of the package.
  • the splicer 6, after having received and cut the two yarn ends to the correct size - eliminating the waste and broken portions of thread, the so called “coarse fibers", by making them get suctioned by the suction pipes 9 and 10 - and having correctly aligned such prepared yarn ends, thus continues to carry out their joining.
  • the splicer 6, once the joining has been carried out, releases the thread letting it return into its winding configuration from the spool 1 to the package 12.
  • the winding process substantially consists of unwinding the supply yarn and of its purification from defects in terms of mechanical consistency or size.
  • the thread 2 In its passage from the spool 1 to the package 12, the thread 2 is controlled by the yarn clearer 11 that detects its dimensional defects, both concerning its transverse and length dimensions.
  • the yarn clearer 11 commands the cutting of the thread all the times that the detected dimension of the thread 2 does not enter within the field of acceptable thread dimensions according to its calibration.
  • the cutting device of the thread can be incorporated in the yarn clearer 11 itself i.e., like in figure 1 , separate like a knife 7, shown situated between the sensor 4 of the thread and the thread tensioning device 5.
  • control unit 16 comprises, amongst its functions, the driving and controlling program for the rejoining procedure, with the connections indicated with a broken line as an example.
  • the defects of the thread 2 being processed are due to irregularities or discontinuities in the previous spinning operations and can be localized or distributed along a more or less long portion of thread.
  • the yarn clearer 11 commands the cutting preferably only when the defect has finished and the yarn has returned to its normal size so as to be provided, on the side of the spool, with a yarn end of thread without defects and that is suitable for being joined.
  • the portion of defective yarn continues to pass in the yarn clearer and to wind around the package 12.
  • the yarn clearer 11 detects and communicates to the control unit 16 the length of the defective portion, before restoring the continuity of the thread through joining, must be suctioned and removed from the yarn wound on the package 12, so as to be provided with a yarn end of thread suitable for being joined on the side of the package as well.
  • the removal of the defective portion wound on the package 12 is carried out by making the winding drum 13 - and with it the package 12 counter-rotate - and by suction the thread with the suction pipe 10 raised against the surface of the package 12, as shown in figure 1 , until the length of the counter-rotation of the winding drum 13 corresponds to the length of the detected defective portion.
  • each new spool it is necessary to withdraw the yarn end of the new spool that, in general, has already been positioned in a predetermined position: as a general rule, it is fitted at the top of the tube of the spool.
  • the same spool suction pipe on the side of the spool 9 is used.
  • the amount of dust that develops during the unwinding of the spool depends both upon how advanced the unwinding is and on the linear winding rate. At the beginning of the spool there is less dragging and a lower amount of dust is formed, whereas at the end of the spool there is greater dragging and more dust is formed. The generation of dust also depends upon the linear winding rate, essentially by centrifugal effect.
  • the winding units that form the winder individually require a substantial suction service both in the steps of restoration of the yarn continuity that has been interrupted and during the normal winding operation for cleaning the path of the thread through removal with the dust suction pipe 20.
  • the continual service for the suction with the dust suction pipe 20, commonly known as "dust removal” requires low head suction, of the order of 50-100 mm W.C. (Water Column), i.e. 500-1000 Pascal, and with flow rates of the order of 50 mc/h, with an hourly energy consumption of the order of 50-70 Wh for each unit.
  • W.C. Water Column
  • flow rates of the order of 50 mc/h with an hourly energy consumption of the order of 50-70 Wh for each unit.
  • the suction service for recovering and handling the yarn ends with the suction pipes 9 and 10 occurs with a variable frequency and with brief durations (around 1-4 seconds for each intervention , but it also requires much higher suction pressure, of the order of 600-900 mm W.C., i.e. 6000-9000 Pascal, so as to give efficiency and safety to the capturing of the yarn ends and to the discharge of the thread waste or "coarse fibers" at the end of the joining in the knotter or splicer 6.
  • the frequency of the thread joining operations while unwinding a spool can vary within very wide limits, according to the quality of the yarn and to the calibration set by the yarn clearer 11.
  • such suction services at high and low depression at the winding units that form the automatic winders are generally supplied by one or more centralized high depression suction units for a non-continuous suction service and by one or more centralized low-depression suction units for the continuous suction during the normal winding.
  • These two types of suction devices are connected to the single winding units with a network of both collectors that separately distribute the suction service to the two depression levels, and collectors that receive and filter the discharges.
  • every winding unit is connected to its general high depression suction header with the interposition of intercepting valves, for example electrovalves, which are only opened for the duration of the suction operations required during its interventions on the yarn ends of the thread, thus taking the needed suction for the amount of time necessary.
  • intercepting valves for example electrovalves
  • the distribution of the continuous low-depression suction service does not normally have intercepting valves and it remains connected to suction service even when the winding unit is not carrying out its normal operation.
  • the continuous low-depression suction service for the dust removal is obtained with individual suction devices for each winding unit, whereas the non-continuous high-depression suction service for the suction pipes for capturing the yarn ends is carried out by a centralized suction device.
  • the continuous low-depression suction service for the dust removal is obtained with a centralized suction device, whereas the non-continuous high-depression suction service for the suction pipes for capturing the yarn ends is obtained with individual suction devices for each winding unit.
  • the present invention is aimed at a new suction layout serving the winding units that form a winder that overcomes the drawbacks described thus far of collective suction systems.
  • the present invention in its most general aspect of suction device which provides all the suction services required by the winding units that form the winder is defined in the first claim. Its variants or preferred embodiments are defined in the dependent claims from 2 to 9.
  • the present invention in its aspect of improved method of winding, is defined in claim 10. Its variants or preferred embodiments are defined in the dependent claims from 11 to 14.
  • Figure 1 illustrates the side view of the winding unit and illustrates the technical problem of the suction service with which it is to be supplied and the suction layout according to the invention.
  • Figures 2A-B an isometric view and a front view, respectively, show the layout of the suction system of the individual winding unit 23, showing the parallelepiped-shaped bulk.
  • Figures 2C-D an isometric and sectioned view, respectively, show one improved embodiment.
  • Figure 3 shows an isometric sectioned view of the detail of the filter for "coarse fibers".
  • Figures 4A , B, C, D illustrate the characteristics of the performances provided by the suction device according to the present invention during its operation.
  • Such a suction unit consists of a rotating suction device with a impeller 25 activated by an electric motor 26 commanded to operate with a speed rotation rate which varies each time according to the necessity of the winding unit.
  • an impeller 25 is a centrifugal impeller.
  • such a motor 26 is a brushless electric motor driven in frequency by the control unit 16 of the winding unit.
  • Such a technical solution makes it possible to vary the depression value that is necessary for the best yarn processing, both in the continuous low-depression dust removal step and in the non-continuous step of capturing the yarn ends at a high-depression.
  • the depression value for dust removal can also be graduated according to the unwinding degree of the spool and according to the winding speed take up, which directly affect the amount of dust developed and that is to be suctioned out from the thread path.
  • the high depression for capturing the yarn ends to be joined can be required at values that are higher than those sufficient for normal yarns.
  • Even the interruption of the thread influences the greater or lower difficulty of capturing the yarn ends, especially on the side of the package. For example, if the interruption of the thread is due to a normal high velocity cut, the cut is clean and the yarn end is easier to recover and requires a lower depression suction value.
  • the low velocity cut forms a more frayed tail that is more adherent to the package, when starting up again the cut forms a fluffy tail, the end of the spool forms a tail with less twists: in all these cases the yarn end is more adherent to the package and a greater depression value is necessary to capture it and detach it from the package.
  • the control unit 16 of the winding unit 23 is therefore capable of varying the high-depression value to be determined in the suction pipes 9,10 that must capture the yarn ends, by driving the suction device 22 at a predetermined speed rotation rate value, according to the interruption modality of the thread.
  • the dust suction pipe 20 of the dust removal service with continuous low-depression suction is connected, with a duct 30, to the suction unit of the winding units 23, intercepted with an air lock 31, for example an electrovalve, again driven by the control unit 16 of the winding unit and it is normally kept open during the normal winding process. It is kept closed during the joining interventions or, in any case, when the winding is not active, excluding the continuous low-depression dust suction pipe 20.
  • the suction pipes 9 and 10 which capture and move the yarn end on the side of the spool and on the side of the bobbin, respectively, to cooperate with the splicer 6 for the restoration of the thread continuity, operate non-continuously with high depression suction during the interruptions of the normal winding. They are respectively connected with a duct 34 to the suction unit 22 of the winding unit, intercepted with an air lock 35, for example an electrovalve, again driven by the control unit 16 of the winding unit and normally kept closed during the normal winding process, excluding the non-continuous high-depression suction pipes (9,10).
  • the air lock 35 is opened during the joining interventions.
  • the individual suction unit 22 which equips the single winding unit 23 either serves the duct 30 for the low-depression dust removal service or the duct 34 for the high-depression suction. When its winding unit is not active, the suction unit can be switched off.
  • Figure 2A , B illustrates the layout of the structure of the single winding unit 23 showing the parallelepiped-shaped bulk and its components of the suction service.
  • the components of the suction system according to the invention are shown enlarged.
  • the non-continuous suction services, required for the suction pipes 9 and 10, and the continuous suction services are both connected to the suction unit 22 with the duct 34 and with the duct 30, respectively, which are alternatively opened and re-closed.
  • the discharge of the suction device 22 is obtained with a fan outlet 27 that discharges the flow into the atmosphere, downwards and away from the path of the thread.
  • an open header can be foreseen for the discharges of the suction of the winding units.
  • a wire mesh filter 41 is arranged having the essential function of withholding the "coarse fibers", removed by the high depression by the suction device 22 upstream, when it is connected to the suction pipes 9 and 10 and is activated at high depression.
  • Figure 3 shows an isometric sectioned view of a detail of the filter 41 for "coarse fibers”.
  • the filter 41 consists of a recipient arranged along the duct 40, in which a wire mesh 43 is arranged for withholding the sunctioned material and in particular the thread waste from the joining of the yarn ends and from the elimination of the defective portions.
  • the filter 41 is connected with a duct 45, intercepted with a valve 46, to a collective system for cleaning said filters 41, consisting of a small-sized main duct 50 that is arranged along the machine and that receives the flow from the ducts 45 of all the winding units 23.
  • the main duct 50 is served by a high-depression suction device 51, that provides for periodically discharging the material from the filters 41 through pneumatic transport to a centralized filter 53 that is periodically opened and emptied out.
  • the periodic cleaning of the filters 41 is carried out for one filter at a time while its winding unit 23 is operating, or in any case for a small number of units 23 at a time.
  • the operation requires a few seconds and is carried out, firstly by closing the air locks 31 and 35 and by isolating the suction device 22 with the closure of the air lock 57 arranged on the initial portion of the duct 40 - thus avoiding that the cleaning of the filter 41 involves its winding unit 23 in its normal operation - and then by opening the discharge valve 46 of the duct 45 and the air lock 56 of the atmospheric air intake 55 of the filter 41, with the suction device 51 operating. Its suction draws air from the air intake 55 and empties out the filter 41 from the material withheld against the lower part of the wire mesh 43 bringing it to the filter 53 that can be emptied out.
  • a pressure gauge 48 is installed, commonly indicated as " ⁇ P meter", which is shown in figure 3 .
  • ⁇ P meter the degree of saturation or blockage of the wire mesh 43 of the filter 41 makes it possible to carry out the cleaning of the filter no longer after a predetermined time period, but only when the filter reaches a predetermined value of pressure drop.
  • Such a knowledge also makes it possible to compensate for possible pressure drop by graduating both the continuous suction for the dust removal, and the non-continuous suction for capturing the yarn ends.
  • a further variant embodiment of the present invention shown in figures 2C-D in an isometric view and a sectioned view, respectively, foresees the installation of a valve 59 for drawing air from the atmosphere, arranged on the centralized filter 53, to be used during the cleaning cycles of the filters 41.
  • the intake valve 59 is preferably arranged downstream of the filter wall of the filter 53 or in other words, immediately upstream of the suction device 51, which is kept in continuous operation during the cleaning in series of the various filters 41 of the various winding units.
  • the actuation of the suction device 51 brings the main duct 50 and the filter 53 to the depression speed value.
  • the air intake valve 59 is opened thus discharging the depression of the circuit during the opening stroke of the valve 46.
  • the corresponding increase in the flow rate modifies the working point of the suction device 51 decreasing the depression value.
  • the yarn in the filter 41 gets caught during the stroke of the valve 46, which is still opening.
  • Such a possibility would make the seal of the valve 46 problematic, negatively affecting the efficiency and the cost-effectiveness of the suction system according to the invention.
  • the air intake valve 59 open the depression is not strong enough to overcome the resistance of the circuit and to suck the yarn from the filter 41 at the opening of the valve 46.
  • the air intake valve 59 closes back up and the working point of the suction device 51 is immediately restored to the depression value that is necessary to clean the filter 41. Once the yarn withheld by the filter 41 has been evacuated, the valve 46 is closed and the cleaning, of further filters 41 of other winding units, continues.
  • Figures 4 are examples of the trends of the suction depressions, of the flow rates and of the powers required by an individual centrifugal suction device serving a winding unit for all the services required.
  • Figure 4A shows, for a centrifugal suction device like the suction device 22, the characteristic trend of the suction depression ⁇ P in Pascal according to the flow rate in mc/h, parametered on different speed rotation rate values.
  • Figure 4B shows for said centrifugal suction device the characteristic trend of the absorbed power, again according to the flow rate in mc/h, parametered on different speed rotation rate values.
  • Figure 4C shows the two trends that are characteristic of the depression ⁇ P required by the winding unit when the high-depression suction valve 35 (curve A) for capturing and handling the yarn ends on the side of the spool and on the side of the package, or the low-depression suction valve 31 (curve B) for the dust removal service are alternatively opened.
  • Such characteristic trends combine with the characteristic curves of the suction device 22 according to figures 4A and 4B .
  • Figure 4D shows the enlarged detail of the trend of the curves A and B for low depression values.
  • figure 4D shows that the device according to the invention makes it possible, for the dust removal service, to obtain good suction flow rates even with modest depression values, since the suction device 22 is directly connected to the suction pipes 9, 10 or 20 which it must serve, thus avoiding pressure drop of the suction distribution and discard collection network.
  • the suction device 22 in order to find and capture the yarn ends in a winding lot of a predetermined yarn, it is considered necessary for the suction device 22 to have a suction depression ⁇ P of 6500 Pascal, on the curve A of figure 4C the point A' can be identified corresponding to the flow rate of 270 mc/h and to a rotation around 6600 rpm .
  • the power required during the suction with such a depression that is to say 1.8 kW can be found through extrapolation.
  • the suction device 22 is required to have a flow rate of 200 mc/h, on the curve B of figure 4D the point B" corresponding to a suction depression of ⁇ P of 400 Pascal and to a rotation of around 1650 rpm, can be identified.
  • the power required for the dust removal service during the normal winding that is to say about 0.25 kW, can be found through extrapolation.
  • the suction system according to the present invention offers substantial advantages.
  • suction values of the single winding units can easily be varied according to the contingent requirements of the single unit, or with the flexibility required to simultaneously process many batches of yarn on the same machine.
  • the suction pipes 9 and 10 are equipped with sensors for detecting the thread inside them, which make it possible to verify whether the thread on their side has been correctly captured before proceeding to its delivery by moving the suction pipes towards the splicer 6. If the sensors of the yarn ends do not indicate that the yarn end has been taken on one of the two sides, the capturing procedure is repeated on that side for a congruous number of times until it succeeds, by varying the procedure for taking the yarn end.
  • the greatest capturing difficulties can occur on the side of the package - especially when the yarn end of yarn is sinewy and falls out from the package - and the withholding procedure is varied by the control unit 16 both for the rotation direction and winding speed take up of the package being unwound and the rewinding of the thread, as well as for the suction duration and, in the case of the present invention, also for the suction intensity.
  • Such a necessity of special recovery cycles of the yarn end occurs, for example, in the processing of thin or sinewy yarns, in the case in which the thread falls sideways off from the package or in the case of cutting at the restarting of the package.
  • the procedure is repeated allowing a winding rotation cycle of the package with normal suction.
  • Such a winding rotation cycle makes it possible to configure the untidy windings caused by the previous missed capturing of the yarn end, to recover the yarn end fallen sideways and, in any case, to make the yarn parallel in the central part of the bobbin due to the absence of the traversing motion.
  • the normal capturing cycle of the yarn end is thus repeated, unwinding the package again and operating with a depression value that is greater than normal.
  • a depression value can in any case be set according to the trend detected in the single winding unit in the previous cycles.
  • the suction device 22 is driven at the highest revolution number to provide a higher depression value for capturing the yarn ends of the thread 2 and, once the yarn ends have been captured, driven at a reduced number of revs to provide a lower depression value during the remaining part of the restoration process of the thread continuity.
  • the technical solution according to the present invention makes it possible to obtain a substantial improvement of the winding process. It should be noted that in the collecting and capturing phase of the yarn end with high depression suction, the depression value can be adapted:
