Abstract

The invention relates to a method and a device for winding a plurality of threads (1.1, 1.2) into a spool (9.1, 9.2). The reels (9.1, 9.2) are simultaneously fixed and wound on two parallel winding spindles (7.1, 7.2). The winding spindle is driven and interacts with a rotatably mounted pressure roller (6.1, 6.2), wherein the pressure roller (6.1, 6.2) bears against the circumference of the reel (9.1, 9.2) with a contact pressure during winding. In order to be able to wind as uniform a reel (9.1, 9.2) as possible on each winding spindle (7.1, 7.2), the contact pressure acting on the two reels (9.1, 9.2) is generated by the gravity loading and/or gravity unloading of the pressure rollers (6.1, 6.2) which are rigidly connected to one another. For this purpose, the pressure rollers (6.1, 6.2) are fixed on a movable support (13), by means of which the pressure rollers (6.1, 6.2) can be guided radially together with respect to the associated spool spindles (7.1, 7.2) and which interact with at least one controllable force transmitter (32).

Description

The method and apparatus that is used for winding several threads

Technical field

The present invention relates to a kind of method and a kind of equipment that is used to implement this method that is used for plurality of threads is wound into reel.

Background technology

When making synthetic filaments, note this trend more and more, side by side abreast a spinning position simultaneously by the many long filaments of a kind of polymer melt melt-spun and then be wound into reel.Therefore known, ten, 12 of melt-spuns, ten six roots of sensation or more how long silk and be wound into reel simultaneously abreast.At this, the coiling of long filament can realize by bobbin-winding machine, wherein reel is fixed on the Spulspindelspulspindel and reels.Reel width and more number of filaments for broad require this bobbin-winding machine to have the Spulspindelspulspindel of corresponding length.Therefore studied the scheme that makes new advances, wherein long filament is wound into reel simultaneously by two Spulspindelspulspindels that be arranged in parallel side by side.Know this method and this equipment by WO03/068648 A1.

In known method and known equipment, long filament is wound into reel simultaneously on two Spulspindelspulspindels that are arranged side by side.Spulspindelspulspindel is driven by a spindle-driving respectively.Set a backer roll for each Spulspindelspulspindel, it can fix with respect to Spulspindelspulspindel by a balancing device (Schwinge) with moving radially.Backer roll leans on the reel circumference during winding filament is become reel.At this, along with the increase of drum diameter, not only backer roll but also Spulspindelspulspindel all change its position.As another degree of freedom, Gu Ding backer roll also can radially move with respect to Spulspindelspulspindel by a slide plate versatilely.But because many degree of freedom make the reel of two Spulspindelspulspindels have difference inevitably on reel structure.Because the mobility separately of two backer rolls keeps for example constant roof pressure power to realize with quite significant adjusting cost in two Spulspindelspulspindels.Therefore the different reel of reeling on two Spulspindelspulspindels is inevitable.

Summary of the invention

Therefore the objective of the invention is, realize a kind of method and apparatus of above-mentioned form, the basic reel uniformly of wherein on two Spulspindelspulspindels, in winding filaments, reeling.

This purpose is achieved by a kind of method and apparatus of following feature according to the present invention.

By the method that is used for plurality of threads is wound into reel of the present invention, wherein, be fixed on reel on two Spulspindelspulspindels that be arranged in parallel side by side simultaneously and reel, drive Spulspindelspulspindel and with rotatably mounted backer roll combined action, described backer roll abuts on the circumference of reel with a roof pressure power during reeling, it is characterized in that, the roof pressure power on the reel of two Spulspindelspulspindels of affacting loads by the gravity via a mutual rigidly connected backer roll of support and/or the gravity unloading produces described support and a controlled power transmitter combined action.

By the equipment of this method of enforcement of the present invention, this equipment has two Spulspindelspulspindels that are used to admit a plurality of bobbins that are arranged side by side, and is used for simultaneously winding filament being become reel; Also have two and attach troops to a unit, be used to drive two Spulspindelspulspindels in the spindle-driving of Spulspindelspulspindel; And have two rotatably mounted backer rolls, described backer roll leans during reeling on the circumference of reel, it is characterized in that, described backer roll is rigidly connected mutually by a support, this support is fixed on the frame so versatilely, make backer roll jointly radially to be guided with respect to affiliated Spulspindelspulspindel, and described support and a controlled power transmitter combined action.

Favourable improvement project of the present invention provides by following feature and characteristics combination.

Feature of the present invention is, in each winder station (Spulstelle), provides identical how much coordinations between Spulspindelspulspindel and backer roll.In addition, can regulate a roof pressure power that be used for reeling, that apply by backer roll by simple mechanism thus at two Spulspindelspulspindel coilings.At this, this roof pressure power is advantageously loaded by gravity of mutual rigidly connected backer roll and/or the gravity unloading provides.For this reason, described backer roll interconnects by a support, it be fixed on versatilely on the frame and with one be used for gravity and load and/or the discharged controlled power transmitter combined action of gravity.Therefore, a special benefits of the present invention is, at each moment of a reel coiling (cycle), the drum diameter that the reel of reeling on two Spulspindelspulspindels has an identical size.Advantageously avoid different reel growths and relevant therewith different drum diameters.

The same volume barrel structure of described reel on two Spulspindelspulspindels can also improve thus, that is, make Spulspindelspulspindel remain identical with distance between shafts between the affiliated backer roll during reeling.

By following preferred embodiment, promptly, in a bigger contact force of setting up like this before the winding filaments between Spulspindelspulspindel and the backer roll, making two backer rolls enter with affiliated Spulspindelspulspindel contacts, winding filament being become reel make contact force be changed to lower roof pressure power later on, can also compensate the production tolerance of this equipment like this.Therefore for example because the production tolerance makes Spulspindelspulspindel go out littler deviation at device interior with respect to the position display of backer roll.Thus especially when winding process begins, between backer roll and affiliated Spulspindelspulspindel, do not produce uniform the contact.In order to suppress this production tolerance, in this method modification, at first between Spulspindelspulspindel and backer roll, be transferred to a high contact force.Measure like this this contact force at this, make because the elasticity of the Spulspindelspulspindel of long cantilever enters two backer rolls and affiliated Spulspindelspulspindel contacts.Described backer roll or Spulspindelspulspindel preferably have parallel elasticity for this reason, get rid of bending phenomenon thus.After winding filament is to the bobbin of Spulspindelspulspindel, make contact force change to lower roof pressure power.

Have at least one unloading cylinder unit (as the power transmitter) according to equipment of the present invention, it is connected with a control unit for this reason.Can make that thus the supporting of backer roll correspondingly reduces when winding process begins, form big gross weight component thus, be used to apply contact force.

In order to realize the even coiling of long filament on two Spulspindelspulspindels, described backer roll preferably has starter ring (Anlaufringe), and they are born when catching with winding filaments and the contacting of Spulspindelspulspindel.Only backer roll just contacts with reel after the basic unit that reels.Preferred heretofore contact force is replaced by roof pressure power.

The starter ring of two backer rolls is preferred identically to be constituted big or smallly, makes each reel all have an identical basic unit thus.

But the external diameter of the starter ring of two backer rolls is differently constituted, so that for example bigger positional tolerance of compensation.There is this possibility equally, replaces being placed in the starter ring on the backer roll, starter ring directly is placed on the circumference of Spulspindelspulspindel.

Also can advantageously unload thus and produce the conversion of contact force to roof pressure power by simple change gravity.

During winding filaments, make the roof pressure power that acts between backer roll and the reel keep constant substantially.But roof pressure power is changed, according to a given force curve so that the reel elasticity that influence is for example determined also influences reel density thus.Described force curve also can comprise a so-called swing, so that the damping of oscillations on the Spulspindelspulspindel.

In order to make two Spulspindelspulspindels,, synchronously drive and control Spulspindelspulspindel according to a favourable improvement project of the present invention as far as possible with the rotating speed of unanimity and thus with the reel circumferential velocity operation of unanimity.For this reason, spindle-driving preferably constitutes by two electrical motors and a controller, and wherein this controller is connected with control setup.

With winding filament with when being laid on the reel circumference, between the periphery of the periphery of reel and backer roll the slippage phenomenon may appear.For fear of this slippage phenomenon that on two backer rolls, form differently, preferably use improvement project of the present invention, wherein make backer roll with machinery or the electric such phase mutual coupling connection of mode, thereby two backer rolls are with identical rotating speed rotation.For the coupling connection, backer roll interconnects by transmission device.This transmission device can constitute with machinery or electric mode, and is adaptive with the rotating speed of realizing two backer rolls.

At this, described backer roll also can additionally oppositely drive by an external driver device, and this is particularly advantageous in the changing bobbins process.But the external driver device of described backer roll preferably is suitable for setting up certain loading coefficient between reel that is driven and backer roll.Therefore can design the external driver device of backer roll like this, make the parts of a conveying always or the parts of a braking act on the circumference of reel.By given loading coefficient, can advantageously influence the long filament stress of the long filament on the coiling, because can regulate the slippage phenomenon of determining between backer roll and the reel.

Since the increase of drum diameter, the offset movement that additionally between Spulspindelspulspindel and backer roll, carries out a stack.This offset movement can carry out separately or jointly, does not wherein lose contacting between backer roll and the reel circumference in principle.

Described offset movement can be realized like this with simple mode and method, makes backer roll and support by slide plate common pilots on an operating slide guideway rail during reeling.Thus in the same adjustment that can guarantee the roof pressure power in two winder stations during the offset movement.

But also have this possibility in principle, backer roll stationkeeping ground keeps and offset movement is only realized by Spulspindelspulspindel.Spulspindelspulspindel is preferably synchronously guided by the spindle bearing of two activities respectively.Thisly for example can also can be used in, when reeling beginning, between backer roll and Spulspindelspulspindel, set up required contacting by the spindle bearing that the reel capstan head constitutes.

But not only motion by backer roll but also the motion by Spulspindelspulspindel realize for the growth of reel also can to make offset movement between backer roll and the Spulspindelspulspindel.Use the spindle bearing of the activity of reel capstan head form also to have advantage, in each winder station, can fix one second Spulspindelspulspindel, change in the district so that can make two Spulspindelspulspindels alternately direct into a winding area and one.

In order to describe the drive scheme of above-mentioned embodiment according to present device, by means of Figure 4 and 5 two possible examples are described below.For clear reason only in Figure 4 and 5 from behind letter winder station 29.1 and 29.2 are shown be used to drive required environment division.

In the drive scheme of Fig. 4, in winder station 29.1, described Spulspindelspulspindel 7.1 is by a supported end 22.1 and spindle-driving 23.1 a couplings connection.For spindle-driving 23.1 sets a controller 24.1, it is connected with the control setup 21 that the upper strata is provided with.The reel 9.1 that is wound on the Spulspindelspulspindel 7.1 is shown in broken lines at this.But the backer roll 6.1 of free rotary ground supporting is positioned on the circumference of reel 9.1, illustrates the same dotted line of this backer roll.Described backer roll 6.1 has a roll end 18.1.For this roll end 18.1 sets a tachogen 20, can record the rotating speed of backer roll 6.1 by it.This tachogen 20 is connected with control setup 21.

In second winder station 29.2, described Spulspindelspulspindel 7.2 is by spindle end 22.2 and spindle-driving 23.2 couplings connection.For this spindle-driving 23.2 sets a controller 24.2, it is connected with control setup 21 equally.The same reel 9.2 that constitutes on Spulspindelspulspindel 7.2 circumference shown in broken lines contacts with second backer roll 6.2.The backer roll 6.2 of second winder station 29.2 can be fixed equally with rotating freely.At this, this backer roll 6.2 is by the backer roll 6.1 couplings connection of a spindle end 18.2 via the transmission device 19 and first winder station 29.1.In this embodiment, this transmission device 19 mechanically constitutes by belt or chain, and two backer rolls 6.1 of two winder stations are turned round with identical rotating speed with 6.2.For winding filaments in winder station 29.1, Spulspindelspulspindel 7.1 is driven by spindle-driving 23.1 cws.Described backer roll 6.1 leans on the circumference of reel to be spooled 9.1 and by friction and drives along opposite direction.

In winder station 29.2, described Spulspindelspulspindel 7.2 drives by spindle-driving 23.2 conter clockwises, so that long filament 1.2 is wound into reel 9.2.At this, described backer roll 6.2 on the circumference of reel 9.2 along clockwise direction with the corresponding rotating speed rotation of backer roll 6.1.By the rotation transmission between the transmission device 19 realization backer rolls 6.1 and 6.2.Two winder stations 29.1 and 29.2 are synchronously reeled, and produce consistent reel 9.1 and 9.2 structures thus on each Spulspindelspulspindel 7.1 and 7.2.

In order to obtain the constant winding speed of long filament 1.1 and 1.2, detect the rotative speed of backer roll 6.1 continuously and give control setup 21 by tachogen 20.The given rotating speed of storing pressurized roller 6.1 in control setup 21.There is a unallowed deviation as long as detect between the given rotating speed of the storage of the actual speed of the detection of backer roll 6.1 and backer roll 6.1, just produces a control signal and be given to controller 24.1 and 24.2.These controllers 24.1 and 24.2 obtain an altered actual speed thus with the desired driving rotating speed that changes spindle-driving 23.1 and 23.2 that turns on backer roll 6.1.Can during long filament 1.1 and 1.2 whole coilings, set up constant reel 9.1 and 9.2 circumferential velocitys thus.At this, described spindle-driving 23.1 and 23.2 preferably constitutes by asynchronous motor.

Consistent with the embodiment that presses Fig. 4 basically at the embodiment shown in Fig. 5.At this, described backer roll 6.1 and 6.2 drives by an external driver device 25, and it constitutes by two electrical motors 28.1 and 28.2 and controllers of attaching troops to a unit 27 at this.Can realize the electrical coupling of backer roll 6.1 and 6.2 and external driver device 25 thus.

But also can make backer roll 6.1 and 6.2 and transmission device coupling connection and only pass through a direct motor drive.

Compare with the embodiment according to Fig. 4, described Spulspindelspulspindel 7.1 and 7.2 drives by spindle-driving 23.1 and 23.2 respectively.Said spindle-driving 23.1 and 23.2 is designed to asynchronous motor or synchronous motor.For spindle-driving 23.1 and 23.2 sets a controller 24.This controller 24 is connected with control setup 21 and constitutes a regulating loop jointly with tachogen 20, so that the maintenance of the circumferential velocity of reel 9.1 and 9.2 is constant.

Be not limited to the single set structure shown in Fig. 1 and 3 according to method of the present invention and according to equipment of the present invention.Therefore for example Spulspindelspulspindel can be fixed on inactive spindle bearing.Also exist the possibility that load to produce contact force by gravity in addition,, provide bigger power or little weight for use for this situation.

Be not limited at the single set structure shown in Fig. 1 according to method of the present invention and according to equipment of the present invention.Backer roll can be fixed with respect to Spulspindelspulspindel by balancing device 1 in winder station with moving radially.The fixing of described Spulspindelspulspindel and backer roll is basically only for realizing that offset movement plays a decisive role.But, can make long filament thus with identical winding speed and thus with substantially invariable long filament stress coiling with the circumferential velocity that offset movement is irrespectively always regulated reel like this.
