Definitions
- the invention relates to a method for winding a continuously starting thread into a bobbin, in which the bobbin is formed on a driven bobbin spindle, which is cantilevered on a movable carrier, in which a pressure roller mounted on a second movable carrier with a by the position of the pressure roller abutment force which can be changed relative to the bobbin is applied to the circumference of the bobbin and in which a change in the center distance between the bobbin and the pressure roller required by the increase in diameter of the bobbin takes place by an evasive movement of the pressure roller and / or by an evasive movement of the bobbin spindle depending on the increasing bobbin diameter, whereby the evasive movement of the winding spindle during the winding travel is controlled according to a predetermined speed function (F v ), which assigns a specific speed (v) to the evasive movement as well as e A winding machine for performing the method.
- F v predetermined speed function
- a method and a winding machine are known from EP 0 374 536, in which the evasive movement of the bobbin receiving the bobbin during Spooling travel is regulated depending on the position of the pressure roller. in this connection the evasive movement of the winding spindle can take place gradually or continuously. There the contact force between the pressure roller and the spool from the relative position between the pressure roller and the spool is a change in Contact pressure inevitable during the winding cycle.
- a method and a winding machine are known from WO 96/01222 which the rotational movement of the winding turret depending on the Angular position of the winding spindle takes place. From the relationship between the Angular position of the winding spindle on the turret and the diameter of the bobbin changes from the changing diameter to the corresponding angular position closed. Since the pressure roller on the spool is stationary, this causes As the bobbin grows, the contact force between the pressure roller increases and the coil. In addition, the method can - especially in the case of soft coils override the winding turret so that the contact between the pressure roller and the coil is completely lost
- the method disclosed in DE 195 38 480 also has the disadvantage that the gradual rotary movement of the winding turret depending on the Angular position of the winding spindle in the course of the winding travel through the Increase in diameter caused inconsistent change in investment power between Coil and the pressure roller causes.
- the known method there is a time specified according to which the angular speed of the turret in Depending on the position of the winding turret is recurrently calculated.
- the object of the present invention is to create a method for Winding a continuously running thread and a winding machine to carry out the method such that the thread throughout Reel travel with a specified investment power or a specified investment aircraft profile on the spool at an essentially constant starting speed the thread is wound up.
- Another object of the invention is to determine the center distance between the Pressure roller and the spool proportional to the increasing diameter change.
- the speed function arranges everyone in the course of the coil trip Coil diameter depends on the temporal increase in diameter of the coil certain speed too.
- the particular advantage of this process is that that the contact force set on the pressure roller is independent of the evasive movement to increase the center distance between the coil and the Pressure roller. The circumferential contact between the coil and the pressure roller remains unchanged as long as the speed of the evasive movement Diameter increase is adjusted.
- the length of the loop around the thread Pressure roller is referred to as the so-called "print length".
- the print length thus defines the length from the point at which the thread runs onto the pressure roller Deposit point of the thread on the bobbin.
- the print length determines the thread guide of the thread on the pressure roller and directly affects the bobbin build-up. So For example, if the print length is too short, the risk of the tee at the Kitchen sink. In these cases, the oscillated thread falls off the end of the bobbin From the bobbin edge. The speed of the evasive movement of the winding spindle leaves therefore pretend that the pressure roller is constantly in a position in which the print length on the pressure roller is constant.
- the winding spindle is equipped with a Speed moves, which is proportional to that in parts of the winding travel Diameter increase of the coil is and thus to an unchanged position of the Pressure roller leads or in some areas not proportional to the diameter increase is the winding spindle, so that the location, the pressure roller in Changed with regard to influencing the investment power or the print length.
- This Process variant is particularly advantageous to certain contact pressure profiles to be observed during the winding trip. You can also use it to define defined print lengths adjust on the pressure roller during the winding cycle.
- the winding travel is through a Marked winding time in which the coil is completely wound.
- the winding time depends on the winding speed, the thread titer and the Coil construction.
- the bobbin has a specific one at each point in the winding cycle Coil diameter. So that each winding time can be a specific one Coil diameter can be assigned.
- Claim 3 can be used particularly advantageously in processes in which the Winding parameters and thread type remain unchanged.
- the control of the Evasion movement of the winding spindle can be carried out as a pure time control.
- the the speed function on which the control is based represents the Relationship between the speed of the evasive movement and the Winding time.
- the position of the carrier of the pressure roller relative to Machine frame or the position of the carrier of the winding spindle relative to Machine frame is determined. Since the pressure roller and the spool are in constant Standing in circumferential contact can only be done from the geometric conditions the respective position of the pressure roller or the calculate the corresponding position of the winding spindle.
- the method variant according to claim 6 has the advantage that for detection of the coil diameter, no additional devices are required.
- To the Keeping thread tension substantially constant during winding the winding speed is regulated with the help of the pressure roller.
- the setpoint specifies a constant speed of the pressure roller. at Deviation of the actual speed from the target speed becomes the drive of the winding spindle controlled in such a way that the desired speed is set on the pressure roller. This information already available in a winding machine can be found at this method variant at the same time to determine the coil diameter be used.
- the speed of the evasive movement is calculated in advance from a parameter which characterizes the temporal increase in diameter of the coil and the coil diameter.
- v is the speed and K the diameter increase parameter and D denotes the coil diameter.
- the pressing force can be kept essentially constant during the winding travel.
- the parameter K, the temporal increase in diameter of the bobbin characterizes during the bobbin travel Determine the stationary support of the winding spindle.
- the position of the pressure roller can be for example by the pivot angle ⁇ of the movable as a swing arm Define the carrier of the pressure roller. From the position of Pressure roller and the coil diameter can be due to the geometric Relation between the pressure roller and the winding spindle through the Calculate the force of the contact force. The speed will then based on the coil diameter, which corresponds to the calculated contact force, and of the diameter increase determined.
- the method according to claim 10 is particularly suitable for determining the contact force and to use it to control the evasion speed.
- the method according to claim 11 is particularly advantageous to a continuously winding thread, with an automatic change between a first and a second winding spindle by rotating one Turret revolver takes place.

During this time, the second winding spindle with one fully wound coil in a so-called parking station. The full coil is in this Time removed from the winding spindle by means of a clearing device and against one Empty sleeve replaced. Then the winding trip is in one Transition area continued such that the center distance through the Evasion movement of the winding spindle is increased.
- a transition area and a winding area can be used for the evasive movement of the winding spindle relevant speed function in the winding area during the winding cycle in the Winding area can be determined.
- the carrier of the Winding spindle (winding turret) silent.
- the increasing coil diameter causes in this phase, an evasive movement of the pressure roller.
- the pressure roller is dodge on a guideway determined by the wearer. When going through this guideway will be the weight component acting on the coil surface the pressure roller constantly change. So everyone corresponds Position of the pressure roller a certain contact force.
- the Actual values of the plant force and the control of the evasive movement of the Based on the winding spindle in the winding area can be advantageous Weight tolerances of the pressure roller and the carrier of the pressure roller as well any hysteresis forces that occur when the pressure roller moves, be compensated.
- the temporal Determine diameter increase in the winding area From the known Sleeve diameter and the current measured per unit of time Spool diameter is the amount of pade deposited on the spool per Determine the time unit so that the diameter increase of the coil and the parameter K are known. This allows the speed function with which the Evasive movement of the winding spindle in the winding area must be carried out for calculate the total winding travel in advance.
- the speed is the Evasion movement of the winding spindle is equal to the angular speed of the Spindle turret.
- the evasive movements of the winding spindle are caused by a drive that drives the respective carrier and its speed can be changed.
- the Drive is advantageously designed as an electric motor, which by means of a Actuator is controlled to change the drive speed.
- the type of carrier for the winding spindle can also be used as a pneumatic cylinder, Pneumatic motor or servo drive.
- the winding machine according to the invention is characterized by this that the signals generated to control the winding speed can be used simultaneously to avoid the evasive movement of the winding spindle Taxes.
- a speed function depending on the Spool diameter or winding time can drive the turret any time of the winding trip to that of the current diameter increase rate appropriate speed can be set. In parts of the winding trip this does not take place, which changes the position of the pressure roller. That can be desired and be brought about in a targeted manner, or it can be brought about by appropriate Changes in the evasive movement can be compensated again.
- the winding machine To provide feedback on the controlled change in position during the winding cycle. to obtain the bobbin turret is the winding machine according to claim 16 particularly beneficial.
- the position of the carrier of the pressure roller or the position of the winding turret continuously detected by a position sensor and the Control device abandoned. Because due to the geometric arrangement everyone Position of the pressure roller and each position of the winding turret only one Coil diameter corresponds to a comparison between the control and the Actual position.
- the design of the winding machine according to is particularly advantageous here Claim 18, which during the winding trip a running calculation of Speed function for controlling the winding turret calculated.

- the winding turret 11 is rotatable in the machine frame 9 of the winding machine stored and is driven by the electric motor 40 in the direction of rotation 23.
- the Electric motor 40 is designed, for example, as an asynchronous motor.
- the Electric motor 40 serves to rotate the turret 11 in the sense that the Center distance between the pressure roller 5 and the winding spindle 14 as it grows Coil diameter is increased.

- the pressure roller 5 is mounted on a rocker 8, so that the Pressure roller makes a movement in radial component to the winding spindle 14 can execute.
- the rocker 8 is on the machine frame 9 about the pivot axis 25 pivoted.
- the pivot axis 25 is through a rubber block formed (not shown here). This rubber block is fixed in the machine frame clamped.
- the rocker 8 is attached to the rubber block, so that the rocker 8 is elastically pivotable. This rubber-elastic storage works like a spring on the rocker 8 in the sense of increasing the contact pressure acts.
- a relief device 12 which can be acted upon pneumatically and which acts on the rocker 8 from below against the weight, the weight, that bears on the pressure roller and thus as a contact force on the spool 17, entirely or partially compensated so that a fine adjustment of a basic value the desired contact pressure between the contact roller and the coil surface is adjustable.
- the relief device 12 can be controlled via a control device 10 to be controlled.
- a position sensor 19 is arranged below the rocker 8.
- the Position sensor 19 detects the stroke of the pressure roller 5 or the pivot angle of the Swing 8 relative to the machine frame 9. The sensor could therefore be considered a Be implemented.
- the sensor 19 is connected to a control device 10 connected.

- the force sensor 41 can for example, be formed by strain gauges, which the bearing load of the pressure roller to capture.
- the coil 17 is wound on the sleeve 16.
- the speed of rotation is here controlled by the actuator 13 and the electric motor 40.
- the control device 10 is based on the speeds of the pressure roller 5 given by the control unit 34 and the Speed of the winding spindle 14 of the currently wound bobbin diameter calculated. From a master curve stored in the control device 10 between the bobbin diameter and the speed of rotation of the bobbin turret the associated coil diameter can thus be associated with it Determine the speed of rotation of the turret.
- the master curve is over a Input 24 of the control device 10 abandoned.
- the control device 10 inputs corresponding control signal to the actuator 13 so that the electric motor 40 with the certain rotational speed is operated. Is the rotational speed of the Turret turret precisely adapted to the diameter increase, so that remains Pressure roller 5 unchanged in its position. If it is too slow The speed of rotation or the speed of rotation changes too quickly Position of the pressure roller. This change in position is detected by sensor 19 detected. The sensor 19 leads its signal directly to the control device 10 Control device 10 is now a correction of the rotational speed so that the Pressure roller is moved back into its new position. So the set remains Contact force between the pressure roller and the spool essentially unchanged.
- the Calculate diameter increase per unit of time This gives you the opportunity to predefined speed function on the actual diameter increase adapt or calculate in advance.
- the control device 10 a computing unit that a running or gradual calculation of the Diameter increase and a correction and advance calculation of the Speed function for moving the winding turret determined. This The speed function is then determined by the control device 10 as Basis for controlling the drive of the winding turret taken.
- a speed function F v is shown in a diagram in FIG. 3, the coil diameter D being plotted on the abscissa and the rotational speed of the turret v being plotted on the ordinate.
- the winding trip is essentially divided into three sections. The first section I is the winding area at the beginning of the winding trip. The second section II is the so-called transition area, and section III is the wikel area.
- the winding area I begins at a coil diameter D 1 .
- D 1 is the diameter of the empty tube. This means that the thread has just been caught on the empty tube and the winding travel begins. In this phase I, the winding turret is not rotated.
- the speed function F v shows zero speed. The winding spindle is thus fixed.
- the increase in diameter between D 1 and D 2 is absorbed by the evasive movement of the pressure roller.
- the pressure roller is thus pivoted evenly on the rocker 8 in this phase.
- the electric motor of the turret is activated.
- a steadily accelerated rotary movement is set on the winding turret.
- the speed function Fv increases linearly. It is thereby achieved that the pressure roller 5 is pivoted back very quickly into its starting position at the beginning of the winding cycle.
- This transition area II is thus passed through very quickly.
- the starting position of the pressure roller represents an optimal working point for the further course of the winding cycle.
- the coil diameter is D 3 . Now the speed of rotation of the winding turret is no longer accelerated.
- the evasive movement of the winding spindle is now adapted to the diameter increase of the coil.
- the speed function F v shows a course which is essentially proportional to the diameter increase, ie the speed of the winding turret decreases hyperbolically with increasing coil diameter.
- the winding cycle is ended after reaching the full winding with the maximum bobbin diameter D 4 .
- FIG. 4 A further diagram is shown in FIG. 4, the reel diameter D being plotted on the abscissa and the contact force P between the reel and the pressure roller on the ordinate. It can be seen here that the contact force in the winding area I initially increases linearly between the diameters D 1 and D 2 . Due to the evasive movement of the pressure roller, the relative position of the pressure roller to the spool changes continuously, so that the weight force of the pressure roller acting on the spool changes, in this case increases. With the simultaneous movement of the pressure roller and the turret, there is only a slight increase in the contact pressure in transition area II. In winding area III, an essentially constant contact force is then achieved by controlling the turret rotation speed.
- the speed function is determined by the specified contact force.
- the change in speed is not proportional to the increase in diameter, since the change in contact force has to be compensated for due to the change in position of the winding spindle. This compensation can be done by step or steady change of position of the pressure roller, which is controlled by the speed of rotation of the winding turret.
- the procedure - as described according to FIG. 3 - leads to the schematic positions shown in FIGS. 5 to 7 in a winding machine.
- the winding turret 11 is stationary in the winding area (FIG. 5).
- the winding spindle 14 thus remains in its position.
- the pressure roller 5 is therefore pivoted on the rocker 8 by an angle ⁇ until the coil diameter D 2 is reached in the direction of movement 32 in order to avoid the increasing coil diameter.
- the evasive movement of the pressure roller can also be done, for example a drive (12) take place which engages the rocker.
- the rotary drive of the turret 11 is activated.
- the control device 10 will control the rotary drive in such a way that the winding turret is moved at a maximum accelerated speed until the pressure roller 5 has returned to its starting position (FIG. 6). In this phase, the winding turret has traveled the angle of rotation ⁇ 1 in the direction of rotation 23.
- the rotary drive of the bobbin turret 11 is controlled by means of the control device 10 such that a rotational speed which is dependent on the diameter increase is set on the bobbin turret.
- the winding turret has traveled the angle of rotation ⁇ 2 .
- both from the position of the pressure roller and the current Coil diameter determine the respective position of the turret or from the Position of the turret and the current diameter of the coil the position the pressure roller.
- a position sensor on the turret can also be used be attached, which detects the angular position of the turret and the Control device gives up. In this case, the position sensor on the rocker Pressure roller is not required.
- the control of the evasive movement can also be done by a The position of the pressure roller and the winding spindle is determined because each position defines a coil diameter.
- the control device is included a position sensor for the pressure roller and with a position sensor for the Turret connected. The sensor signals become the current one Coil diameter and the diameter increase determined. The The increase in diameter then leads from a stored master curve to the speed of the evasive movement to be set.
- the method according to the invention cannot only be carried out by one according to FIGS. 1 and 2 described winding machine are executed but is also advantageous Can be carried out by winding machines with only one winding spindle.
- the winding spindle is stored on a movable support.
- the carrier of the winding spindle is there coupled with an inverter-controlled drive.
- the carrier can be as Swing arm to be executed, which is mounted on one side on the machine frame.
- the carrier of the winding spindle or the pressure roller as one Linear guide be carried out in the case of a carriage by a linear drive is driven.
- the method according to the invention is also suitable for changing the contact force solely by changing the rotational speeds of the carrier of the winding spindle or winding turret.
- the contact force acting between the pressure roller and the spool results from the weight of the pressure roller.
- 8 shows the force ratio between the pressure roller 5 and the spool 17.
- the weight of the pressure roller is denoted by G, which has a vertical direction of action.
- the contact force P, which acts between the pressure roller and the spool 17, has, as the direction of action, the connecting line between the axis center M A of the pressure roller and the axis center M S of the winding spindle.
- the coil 17 has the diameter D 1 in this phase.
- the coil 17 now grows from the diameter D 1 to the diameter D 2 in the course of the winding cycle.
- the position of the winding spindle is not changed.
- the axis center M A of the pressure roller will move on a circular guide path F A , the center of which is formed by the axis center M T of the pivot axis of the carrier or the rocker.
- the carrier or the rocker of the pressure roller is thus shifted by the angle ⁇ . Since the weight G of the pressure roller remains unchanged, one that acts between the pressure roller 5 and the spool 17 will act due to the changed angular position. Result in contact force P ⁇ .
- the winding machine according to the invention thus offers the possibility of setting a contact force which is desirable for the formation of the bobbin simply by changing the position of the pressure roller.
- the weight G of the pressure roller could be increased or relieved by a force sensor as required by a constant value. If a contact force desired for the bobbin build-up is set by changing the position of the pressure roller, the pressure roller is then held in position by moving the winding spindle away by means of the turret.
- Constant control of the rotational speed of the carrier or of the turret take place in that a sensor detects the speed of the evasive movement detected and given as the actual value of the control device.
- the Control device can therefore a constant based on an actual-target comparison Speed correction can be made.
- the method according to the invention can also advantageously be used to change the thread wrap on the pressure roller during a winding cycle.
- the pressure roller is shown in two different positions in FIG. 9.
- the pressure roller can be guided, for example, by a rocker which is rotatably mounted in the pivot axis MT. In the lowest position of the pressure roller, a coil with the diameter D 1 is wound on the winding spindle. In the upper position of the pressure roller, the bobbin on the winding spindle has grown to the diameter D 2 .
- the pressure roller and the winding spindle are so to the thread run that a the surface line of the pressure roller running thread 1 only after partial wrap placed on the pressure roller on the spool surface of the spool to be wound becomes.
- the looping area of the thread 1 on the pressure roller is here characterized by the angle ⁇ .
- This partial length of the perimeter is also called so-called print length
- the print length has a significant influence on the coil structure. To achieve an undisturbed coil build-up is one Minimum print length required on the pressure roller.
- the wrap angle of the pressure roller at the lower position is marked Y1.
- the wrap angle in the upper position of the pressure roller is designated by ⁇ 2 , the wrap angle ⁇ 2 being smaller than the wrap angle ⁇ 1 .
- the print length can thus be influenced solely by changing the position of the pressure roller.
- the print length will increase as the axial distance between the winding spindle and the pressure roller increases.
- Such a change in the print length can be compensated for by changing the position of the pressure roller in the meantime.
- the speed of the winding turret can also be determined as a function of a print length to be maintained on the pressure roller.

- Verfahren zum Aufspulen eines kontinuierlich anlaufenden Fadens zu einer Spule, bei welchem die Spule auf einer angetriebenen, an einem beweglichen Träger (8) auskragend gelagerten Spulspindel gebildet wird,
bei welchem eine an einem zweiten beweglichen Träger (8) gelagerte Andrückwalze (5) mit einer durch die Stellung der Andrückwalze (5) relativ zur Spule veränderbaren Anlagekraft am Umfang der Spule anliegt und
bei welchem eine durch den Durchmesserzuwachs der Spule erforderliche Veränderung des Achsabstandes zwischen der Spule und der Andrückwalze (5) durch eine Ausweichbewegung der Andrückwalze (5) und/oder durch eine Ausweichbewegung der Spulspindel (14) in Abhängigkeit vom wachsenden Spulendurchmesser erfolgt, wobei die Ausweichbewegung der Spulspindel (14) während der Spulreise nach einer vorgegebenen Geschwindigkeitsfunktion (Fv) gesteuert wird, die im Verlauf der Spulreise jedem Spulendurchmesser (D) eine bestimmte Geschwindigkeit (v) der Ausweichbewegung zuordnet,
wobei die durch die Geschwindigkeitsfunktion (Fv) bestimmte Geschwindigkeit (v) zumindest in Teilbereichen der Spulreise von der zum Ausgleich des Durchmesserzuwachses erforderlichen Geschwindigkeit abweicht, so dass sich die Lage der Andrückwalze (5) verändert. - Verfahren nach Anspruch 1
dadurch gekennzeichnet, daß
die durch die Geschwindigkeitsfunktion (Fv) bestimmte Geschwindigkeit (v) in anderen Teilbereichen der Spulreise dem Durchmesserzuwachs der Spule während der Spulreise entspricht, so dass die Spule in diesen Teilbereichen bei im wesentlichen unveränderter Lage der Andrückwalze (5) anwächst. - Verfahren nach einem der Ansprüche 1 oder 2,
dadurch gekennzeichnet, dass
die Steuerung der Ausweichbewegung der Spulspindel (14) während der Spulreise in Abhängigkeit von einer Wickelzeit erfolgt. - Verfahren nach einem der Ansprüche 1 oder 2,
dadurch gekennzeichnet, dass
die Steuerung der Ausweichbewegung der Spulspindel (14) während der Spulreise in Abhängigkeit von dem Spulendurchmesser erfolgt. - Verfahren nach Anspruch 4,
dadurch gekennzeichnet, dass
der Spulendurchmesser durch die Stellung des Trägers (8) der Andrückwalze (5) und/oder die Stellung des Trägers der Spulspindel erfasst wird. - Verfahren nach Anspruch 4,
dadurch gekennzeichnet, dass
der Spulendurchmesser durch das Drehzahlverhältnis der Drehzahl der Andrückwalze (5) und der Drehzahl der Spulspindel (14) bestimmt wird. - Verfahren nach einem der Ansprüche 1 bis 6,
dadurch gekennzeichnet, dass
die Geschwindigkeit (v) der Ausweichbewegung aus einer den zeitlichen Durchmesserzuwachs der Spule bestimmende Kenngröße (K) und dem Spulendurchmesser (D) als Funktion der Wickelzeit oder des Spulendurchmessers vorausberechnet wird. - Verfahren nach Anspruch 7,
dadurch gekennzeichnet, dass
die Kenngröße (K) während der Spulreise bei stillstehendem Träger der Spulspindel (14) ermittelt wird. - Verfahren nach einem der Ansprüche 1 bis 6,
dadurch gekennzeichnet, dass
die Geschwindigkeit (v) der Ausweichbewegung aus einer den zeitlichen Durchmesserzuwachs der Spule bestimmenden Kenngröße (K), dem Spulendurchmesser (D) und der Stellung der Andrückwalze (a) als Funktion der Wickelzeit oder des Spulendurchmessers vorausbestimmt wird. - Verfahren nach Anspruch 9,
dadurch gekennzeichnet, dass
die Kenngröße und die Anlagekraft zwischen der Andrückwalze (5) und der Spule in Abhängigkeit von der Stellung der Andrückwalze (5) relativ zur Spule während der Spulreise bei stillstehendem Träger der Spulspindel (14) ermittelt wird. - Verfahren nach einem der Ansprüche 1 bis 8, wobei der Träger der Spulspindel durch einen Spulrevolver mit einer zweiten Spulspindel (14) gebildet wird,
dadurch gekennzeichnet, dass
