Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a winding machine for winding a Spulguts to a coil. Preferably, the winding material to be wound is a winding material which is sensitive to deflections and the resulting transverse forces. For example, lateral forces as a result of deflections lead to damage of edges of the Spulguts, deformations of Spulguts or breaks of any fibers of the Spulguts. In the Spulgut is in particular a yarn or a thread or band-shaped Spulgut. Preferably, the Spulgut is formed pliable. The wadding can be a single filament or a multifilament (for example with more than 12,000 individual filaments up to 300,000 individual filaments). For example, the winding material may be strips with any cross-sections, in particular with a rectangular cross-section up to 5 × 20 mm ² and / or with a cross-section with a ratio of the width to the thickness greater than or equal to 4.0 or 5.0. It is also possible that the wadding is prepreg materials, such as carbon or glass fiber ribbons in a non-cured plastic matrix. It is also possible that the winding machine according to the invention is used for winding material formed by a carbon fiber tape or (copper) strands. In this case, winding speeds of up to 1,500 m / min are preferably used.

STATE OF THE ART

For the winding of a coil on a bobbin tube on the one hand, it is necessary for the bobbin tube to be rotated with a rotational movement in order to wind the bobbin with an increasing angle of wrap onto the lateral surface of the bobbin tube and a forming coil. On the other hand, a traversing movement is required in order to supply the material to be winder alternately during the laying of different axial regions of the bobbin tube and the winding forming thereon. Depending on the vote of the rotation of the Coil sleeve and the traversing movement different Spulbilder (see also DIN ISO 5238) can be generated.

Embodiments of winding machines are known in which upstream of the bobbin tube and the winding formed thereon, a traversing device is arranged, which is supplied to the Spulgut from a turn upstream roll. The traversing device has a traversing yarn guide which is moved back and forth in an oscillating manner parallel to the axis of rotation of a spindle on which the bobbin tube with winding forming thereon is arranged. Depending on the position of the traversing yarn guide, the winding material passes from the traversing yarn guide into different axial regions of the bobbin tube and the forming winding. The problem here may be that in the area of the traversing yarn guide (and the tracer thread upstream role), a deflection of the Spulguts perpendicular to the longitudinal extent, which for a sensitive Spulgut, ribbon-shaped Spulgut or Spulgut with a non-circular, such as rectangular or flat cross-section, too Problems may result, in the worst case, the deflection of the Spulguts can cause damage to the Spulguts. On the other hand, changes depending on the position of the traversing yarn guide the length of the way from the role of the traversing yarn guide to the point of application of Spulguts to the bobbin and the forming winding, whereby additional measures are required if the tension in the Spulgut during the winding cycle in a predetermined Should lie voltage range and / or the rate of decrease of the Spulguts by the forming winding should not be dependent on the position and movement of the traversing yarn guide.

The publication DE 103 24 179 A1 discloses a winding machine, which should be particularly suitable for winding operations with a ribbon or strip-shaped winding material with a rectangular or flat cross section with a guarantee of small forces acting on the Spulgut forces and accelerations. Here, the winder is to allow the winding of coils with the Spulbild a cross-wound bobbin a sensitive Spulgut. The document suggests that no iridescent reciprocating yarn guide is used. Rather, the bobbin is fed to the bobbin via a roller which is not moved iridescent parallel to the axis of rotation of the spindle. Instead, the traversing motion is brought about by the rotating spindle, together with the gearbox and the motor for driving the spindle via another motor parallel to the Rotation axis of the spindle is reciprocating relative to the role reciprocated. In this case, the distance between the spindle upstream of the spindle and the developing winding is kept constant during the winding cycle. This can be done by moving the roll with a roller bearing dancer plate (and possibly other roles) away from the axis of rotation of the spindle with increasing diameter of the developing winding. Alternatively, it is proposed that with increasing enlargement of the diameter of the developing winding, the unit formed with the spindle, the gear and motor is moved away from the roller in addition to the application of the traversing movement transversely to the axis of rotation of the spindle.

Another winding machine, in which also the rotating spindle a traversing relative to a feed roller for applying a Spulguts (here a winding material in the form of PP, PE and PET tapes, aluminum composite films, coated tapes, rubber bands, Teflon tapes, a and double-sided adhesive tapes, paper tapes, tapes made of nonwovens or prepreg tapes) is marketed by the applicant under the designation "SAHM 460XE", whereby cylindrical, biconical coil forms, disc coils or flanged coils can be produced hereby.

The publication WO 2007/113045 A1 proposes a first embodiment in which on a fitted with a kind of spline axially fixed, offset by a drive in rotation spindle axially displaceable under the transmission of rotational movement a coil holder is mounted. The bobbin holder is axially reciprocated on the spindle to bring about a traversing motion via an actuator by a driver. For a second embodiment, the motor shaft itself (with both the rotatably and axially fixed coil holder) is both axially reciprocated and rotated. For this purpose, the motor shaft is rotatably connected to a spindle whose internal thread interacts with another spindle, which is set in rotation by a first drive. The external toothing of the former spindle is engaged with a spindle nut which is rotated by a second actuator. A drive of the two actuators with the same speeds leads to a pure rotation of the motor shaft with the coil holder. If, however, only the first actuator is driven, there is a purely axial movement of the motor shaft with the coil holder. When superimposing different speeds of the actuators, the motor shaft with the coil holder performs both a rotational movement and a superimposed traversing movement.

According to the document JP S 62 88779 A the winding takes place on a bobbin and a spindle, which are axially fixed. Here is a conventional traversing used, which is moved back and forth via a Kehrgewindewelle. For this embodiment, the bobbin is thus not iridescent moved relative to the spindle. For another embodiment, a frame, on which the motor and the spindle are mounted, is moved by way of a spindle drive. For this embodiment, thus changing an axial position of the spindle.

According to the document DE 455 581 C a spindle is mounted axially displaceable in a bearing. The drive of the spindle while maintaining the axial displacement degree of freedom via a guided in a longitudinal groove of the spindle entrainment wedge, which is driven by the drive wheel. A reciprocating movement of the spindle is caused by a Kehrgewindenut the spindle, in which engages a held on a sleeve fixed to the bearing carrier. The superimposed rotational movement and traversing movement of the spindle is finally transmitted via a friction clutch on the take-up drum.

Further prior art is from the documents US 3,356,307 A . JP S48 42032 Y1 and JP 2002 241054 A known.

OBJECT OF THE INVENTION

The present invention has for its object to provide a winder with an alternative way to bring about a traversing movement, which is particularly suitable for winding operations with a sensitive Spulgut.

SOLUTION

The object of the invention is achieved with the features of the independent claim. Further preferred embodiments according to the invention can be found in the dependent claims.

DESCRIPTION OF THE INVENTION

The invention relates to a winding machine with a spindle whose axial position does not change during iridescent application of the Spulguts to a bobbin tube and to a forming on the bobbin winding. While for such designs according to the prior art, the generation of the traversing movement has necessarily required the use of a traversing device with a traversing yarn guide with the associated, initially explained disadvantages, a solution is proposed according to the invention, in which the use of a traversing device is unnecessary (which is quite in Frame of the invention can additionally use a traversing device):

According to the invention, a traversing carriage is mounted on the spindle. The traversing carriage is axially movable relative to the spindle, so that the traversing carriage, caused by a suitable drive, can perform a traversing movement relative to the spindle. The traversing carriage is coupled to the bobbin tube or at least temporarily coupled (for example, frictional and / or positive fit) that the traversing movement of the traversing carriage is transferable to the bobbin tube.

The solution according to the invention is based, in particular, on the recognition that the basic principles known from the prior art are disadvantageous for the generation of the traversing movement. Thus, the use of a traversing device requires the undesired deflection of the Spulguts. In contrast, for example, according to DE 103 24 179 A1 or according to the product "SAHM 460XE" of the applicant, the entire spindle, u. U. also moves with the associated gear and the motor for driving the spindle for the generation of traversing movement, the drive for generating the traversing movement must move a relatively large mass, which is particularly problematic for a fast traversing movement with a quick reversal of the direction of movement can. In addition, u. U. the storage cost and space when a bearing of the spindle must be made such that it can perform both a rotational movement and a traversing movement.

While avoiding these disadvantages of the known basic principles, the invention proposes a new basic principle, in which the spindle does not have to be moved axially and only the traversing carriage executes the traversing movement, whereby the traversing movement for moving mass can be reduced and yet the deflection via a traversing device is unnecessary.

According to the invention, a rotating spindle is used, which is driven by a suitable drive. In this case, the traversing carriage is coupled to the spindle or at least temporarily coupled (for example, frictional and / or positive fit) that the rotational movement of the spindle can be transferred to the traversing carriage. The traversing carriage is then coupled to the bobbin tube or at least temporarily coupled, that (in addition to the transmission of traversing movement of the traversing carriage on the bobbin tube), the rotational movement of the traversing carriage is transmitted to the bobbin. On the bobbin tube winding is then created by superimposing the rotary motion and the traversing movement of the bobbin tube.

In the case of the winding machine according to the invention, the spindle has an inner bore in which a traversing mechanism which carries out the traversing movement, for example an actuating rod, extends. The extending in the inner bore of the spindle actuating mechanism is coupled to the traversing carriage, so that the traversing movement of the actuating mechanism, u. U. even by means of an over- and / or reduction, can be transmitted to the traversing carriage or traversing sleeve.

While in principle it is possible that the coupling of the traversing carriage with the spindle via any coupling measures such as a clutch, a frictional u. Ä. Can, the invention proposes in an embodiment of the winder, that the traversing carriage is coupled via a positive connection in the circumferential direction with the spindle. Such a positive connection represents a special reliable possibility for the transmission of the drive torque for the generation of the rotational movement of the traversing carriage. U. by means of such a positive connection in the circumferential direction still be ensured in a very simple manner, the axial degree of freedom of the traversing carriage relative to the spindle. To name just a few non-limiting examples, the positive engagement in the circumferential direction by engagement of a projection of the traversing carriage in a longitudinal groove of the spindle (or a radial projection of the spindle in a longitudinal groove of the traversing carriage) can be ensured, while with movement of the projection along the longitudinal groove axial degree of freedom can be ensured, while at the same time a kind of guidance can be provided by the engagement of the projection in the longitudinal groove.

There are many possibilities for the basic design of the traversing carriage. For a proposal of the invention, the traversing carriage is formed with a type traversing sleeve. The traversing sleeve has a (preferably continuous) bore or recess into which or through which the spindle extends. This can be done by the bore or recess already the leadership of the traversing sleeve relative to the lateral surface of the spindle for the traversing movement. On the other hand, can be arranged radially outboard of the traversing sleeve, the bobbin on which the winding is to be wound. U. U. results in radially nested construction of the bobbin, the traversing sleeve and the spindle is a very compact, small radial design.

In a particular embodiment, a driver is mounted with the traversing sleeve, which positively coupled in the circumferential direction of the spindle with the traversing sleeve. Such a design of the traversing carriage with the traversing sleeve and the driver simplifies u. U. the manufacture and / or assembly of the traversing carriage.

In principle, it is possible for the actuating mechanism, for example from a machine frame or even from the side of the machine frame, which faces away from the spindle, to extend only through part of the spindle in the region of the inner bore. In this case, the actuating mechanism may be coupled in the arranged in the spindle end portion via a suitable coupling means through a recess or a slot of the spindle through with the traversing carriage. To mention only a non-limiting example, the coupling means may be formed with a radial pin of an actuating rod extending through a slot of the spindle, wherein the outer end portion of the pin slidably or with the interposition of a rolling bearing receiving in an inner circumferential groove of the traversing carriage. In this case, the inner bore of the spindle can only extend in a part of the spindle facing the machine frame, while the freely projecting end region of the spindle does not have an inner bore or here the inner bore can be closed with a suitable closure means.

For another proposal of the invention, the oscillating motion actuating mechanism extends with an actuating rod extending through the internal bore of the spindle to the free end portion of the spindle so that the actuating rod extends along the entire length of the spindle. By doing free end region of the spindle, the actuating rod is coupled via a coupling device with the traversing carriage. While for the embodiments described above, the traversing carriage is driven from the side of the machine frame (which can be done radially outward from the spindle or through the internal bore of the spindle can be done), the traversing motion is first completely through the actuating rod for this proposal of the invention passed the spindle and then passed over the coupling device in the free end region of the spindle radially outward, where then the return of the drive movement is again in the direction of the machine frame to the traversing carriage.

It is quite possible that rotates the traversing movement operating rod with the traversing carriage for this embodiment. In this case, the drive for generating the traversing movement must be able to receive a corresponding rotational movement, or between a drive for generating the traversing movement and the actuating rod, a suitable axial bearing element must be arranged, which transmits the axial forces to generate the traversing movement, but the counteracts rotating movement of the actuating rod to a non-rotating actuating tappet of the actuator.

For a particular proposal of the invention, the arranged in the free end portion of the spindle coupling means comprises a thrust bearing, which transmits the traversing movement of the actuating rod on the traversing carriage, but at the same time allows a relative rotational movement of the traversing carriage relative to the actuating rod. In this case u. U. the actuating rod itself no rotational movement, but this is exclusively the traversing movement, ie an axial movement coaxial with the longitudinal axis of the spindle exposed.

Of particular importance may be a seal of the inner bore of the spindle and any arranged here or in the region of the coupling device bearing. For example, the winding process for the Spulgut be associated with a dust or dirt development or with the separation of fiber fragments, which could lead to impairment of the function of bearing or guide elements. This can be inventively taken into account with a development of the winder, in which the coupling device closes the inner bore of the spindle end face.

For the coupling of the traversing carriage with the bobbin tube various known per se coupling devices can be used. To name only a non-limiting example, can be used as a coupling device between traversing carriage and bobbin tube coupling device, as in the document DE 10 2010 044 107 A1 or DE 37 44 600 A1 is described. For a particular proposal of the invention, the traversing carriage can be coupled to the bobbin tube via a bobbin tube tensioning device.

It is possible in this case for the purpose of actuating the bobbin tube tensioning device to clamp a suitable actuator clamping jaws to the interior of the bobbin tube. For a particular proposal, the bobbin tensioning device assumes its clamping position without actuation, in which the rotational movement of the traversing carriage and / or the traversing movement of the traversing carriage is transferable to the bobbin tube. By contrast, the bobbin tensioning device assumes a release position with actuation, in which the bobbin tube (and the winding created thereon) can be removed from the traversing carriage and a new bobbin tube can be pushed onto the traversing carriage. This embodiment is based on the finding that it is advantageous if the required coupling effect between the traversing carriage and the bobbin tube is ensured in each case without actuation for the winding cycle. Only for the u. U. shorter lasting process of changing the bobbins on the spindle is a separate operation required, bringing the operating times u. U. are reduced. Furthermore, the reliability of the winding process can be ensured for this embodiment, even in the event of failure of the bobbin tube tensioning device, without it being possible for the winder and dangerous operating situations to be impaired. On the other hand, any failure of the bobbin tube tensioning device develops only effect for the change of the bobbin tube.

For a particular proposal of the invention, the bobbin clamping device is formed with an elastically radially deformable clamping sleeve. In the clamping position, the lateral surface of the elastically radially deformed clamping sleeve without actuation of the bobbin clamping device is brought into interaction with the inner surface of the bobbin tube, which preferably takes place in the form of a positive and / or frictional engagement. In order to bring about the required radial deformation, the choice of material and / or the shape of the clamping sleeve may be suitably adapted. For example, the clamping sleeve with at least one extending in the axial direction of the frontal or center slot be formed, which reduces the radial stiffness of the clamping sleeve in this axial region of the clamping sleeve. It is also possible that a slot extends both in the axial direction and in a partial circumferential direction, so that the slot releases a partial circumferential region which can be deformed well elastically with reduced radial rigidity. It is possible that the traversing carriage on the one hand and the bobbin case on the other hand are formed separately from each other. In a preferred embodiment, however, the traversing slide integrally forms the bobbin tube, whereby the construction cost is further reduced and a very compact design can be brought about.

To bring about the operation of the bobbin tube tensioning device and in particular the elastic radial deformation of the clamping sleeve, there are basically many possibilities, wherein any actuators and actuating mechanisms can be used. In the event that an additional actuator is to be saved for actuating the bobbin tube tensioning device, the invention proposes that the bobbin tube tensioning device is actuated in a movement-controlled manner by the movement of the traversing slide and / or released. For this embodiment, therefore, the actuator, which is responsible for the traversing movement of the traversing carriage, also be responsible (in particular in a particular adjustment range such as an end region of the traversing movement or even an adjustment range away from the path for the normal traversing movement) for the operation of the bobbin tensioning device ,

Basically, there are many possibilities for the movement-controlled actuation of the bobbin tube tensioning device by the movement of the traversing slide. For a winding machine according to the invention, the clamping sleeve has an inclined surface, which may be formed, for example, as a cone inclined surface. Movement controlled by the movement of the traversing carriage, that is, in response to the actuation of the actuator for generating the movement of the traversing carriage, the inclined surface can be pressed against a particular machine frame fixed actuating surface, which is preferably a cone-actuating surface. The force exerted by the actuating surface on the inclined surface contact force can cause a radial elastic deformation of the clamping sleeve, which is then responsible for bringing about or solving the connection between the clamping sleeve and the bobbin tube.

As an actuator for generating the movement of the traversing carriage, any actuator with any gear or other drive kinematics can be used. For a proposal of the invention, a spindle drive is used in the winder. A spindle of the spindle drive is rotated by an electric drive. By contrast, a rotationally fixed, but axially displaceable spindle nut of the spindle drive is coupled to the traversing carriage for generating and / or transmitting the traversing movement. Alternatively, it is possible that an axially fixed spindle nut of the spindle drive is rotated by an electric drive. A rotationally fixed, but axially displaceable spindle of the spindle drive is coupled to the traversing carriage to generate and / or transmit the traversing movement.

It is also possible that an electric linear drive is coupled to the traversing carriage for generating the traversing movement. This may be, for example, an axial stepper motor. But it is also possible, for example, that by means of a rotary electric drive in a linear drive a translationally guided coupling element such as a rack or a circumferential belt is reciprocated.

In an alternative embodiment, the invention proposes that in the winder a sweeping is present. A Kehrgewindewelle the Kehrgewindetriebs is driven by an electric drive. In a Kehrgewinde the Kehrgewindewelle a rotatably, but axially displaceably mounted driver is guided, which is coupled to the traversing carriage.

DESCRIPTION OF THE FIGURES

Fig. 1 shows a winder 1. The winder 1 has an electric drive 2, which is held on a machine frame 3 of the winder 1. A driven by the drive 2 drive wheel 4 is connected via a traction means 5 such as a toothed belt or a chain in driving connection with a driven gear 6. The output gear 6 is rotationally fixed, coupled here via a feather key 7, with a spindle 8. By operating the drive 2, a rotational movement 9 of the spindle 8 can be brought about with a transmission or reduction depending on the transmission ratio between the drive wheel 4 and the driven wheel 6.

The spindle 8 is rotatably supported by a spindle bearing 10 about a longitudinal and rotational axis 11 on the machine frame 3. Here, the spindle bearing 10 forms a so-called flying storage. The spindle bearing 10 is arranged on one side of the machine frame 3, while the freely projecting portion of the spindle 8, in which the coil 12 is wound, is arranged on the other side of the machine frame 3.

The spindle 8 is formed as a hollow shaft 13 with a continuous inner bore 14. Through the inner bore 14 of the spindle 8 extends an actuating rod 15. The projecting from the spindle bearing 10 end portion of the actuating rod 15 is connected to an actuator 16, here a linear drive 17. In the other end region, which protrudes from the spindle 8, the actuating rod 15 is coupled via a coupling device 19 with a traversing carriage 20. By means of the actuator 16, the actuating rod 15 coaxial are reciprocated to the rotation axis 11, whereby the actuating rod 15 performs a traversing movement 18.

Here, the traversing carriage 20 is formed with a traversing sleeve 21, which is formed integrally with a clamping sleeve 22 for the illustrated embodiment. The coupling device 19 allows a transmission of axial forces, so that the traversing movement 18 is transmitted from the actuating rod 15 to the traversing carriage 20 via the coupling device 19. On the other hand, the coupling device 19 allows for the illustrated embodiment, a relative rotation of the traversing carriage 20 relative to the actuating rod 15. As will be explained in more detail below, so that the traversing carriage 20 can generate the rotary motion generated by the drive 2 9 with the spindle 8, while the actuating rod 15 performs no rotational movement 9, which simplifies a coupling of the actuating rod 15 with the actuator 16. (It is quite possible, however, that the coupling device 19 is not designed with such a relative rotational degree of freedom.) In this case, the actuating rod 15 rotates with the traversing carriage 20, while a rotational degree of freedom elsewhere, in particular in the coupling region of the actuating rod 15 with the actuator 16 can be provided.)

The traversing carriage 20 is axially displaceable, but rotatably guided on the spindle 8. For the illustrated embodiment has the traversing sleeve 21, with which the traversing carriage 20 is formed, for this purpose, a recess in which a driver 23 is attached, which takes place for the illustrated embodiment by end-side screwing. The driver 23 and the traversing sleeve 11 form (including the screw) a flush, cylindrical lateral surface. The driver 23 forms a relation to the inner surface of the traversing sleeve 21 protruding rib or a projection 24 which engages in a recess 25 or groove of the lateral surface of the spindle 8. By the engagement of the projection 24 of the driver 23 in the recess 25 of the spindle 8 is a Positive engagement generated in the circumferential direction, so that the rotational movement 9 is transmitted from the spindle 8 via the lateral boundary of the recess 25, the projection 24, the driver 23 to the traversing sleeve 21 and thus the traversing carriage 20. The recess 25 is formed with a larger axial extent in the manner of a long groove or an elongated hole, so that the projection 24 can move in the axial direction in the recess 25 without the positive engagement in the circumferential direction is eliminated. This degree of freedom of movement of the projection 24 in the recess 25 is at least so large that the projection 24 and thus the traversing sleeve 21 and the traversing carriage 20 relative to the spindle 8, the traversing movement 18 can perform while driving the traversing carriage 20 through the spindle 8 with respect to the rotational movement. 9

Via a coupling device or bobbin tube tensioning device 26 is on the traversing carriage 20, here the traversing sleeve 21, a bobbin tube 27 held such that the bobbin tube 27th

• both the generated by the actuator 16 and transmitted via the actuating rod 15 and the coupling device 19 traversing movement 18 of the traversing carriage 20 performs
• as well as the generated by the drive 2 and transmitted from the spindle 8 via the driver 23 to the traversing carriage 20 rotational movement 9 performs.

On the bobbin tube 27, a winding 28 of the coil 12 is created in a conventional manner by superimposing the rotary motion 9 and the traversing movement 18. The traversing movement 18 of the traversing carriage 20 leads to an axial relative movement between the traversing carriage 20 and the spindle 8, which is guided by guide units 29a, 29b, in particular sliding bearing, which are interposed between the inner surface of the traversing sleeve 21 and the lateral surface of the spindle 8. For the illustrated embodiment, the guide units 29a, 29b are arranged on both sides of the driver 23. Between the actuator 16 and the traversing carriage 20, an actuating mechanism 30 is interposed, which transmits the traversing movement 18 to the traversing carriage 20 or generates this. For the illustrated embodiment, the actuating mechanism 30 is formed with the actuating rod 15 and the coupling device 19. For this actuating mechanism 30, the traversing movement 18 is completely guided by the spindle 8 designed as a hollow shaft 13 by means of the actuating rod 15, guided radially outwardly in the region of the coupling device 19 and then recirculated radially outwardly from the lateral surface of the spindle 8 again. In a semi-longitudinal section thus results in a power flow corresponding to a horizontal U, wherein the coupling means forms the base leg of the U, while the actuating rod forms the radially inner side leg of the U and the other, parallel and radially outer side legs of the U is formed by the traversing carriage 20. This U-shaped power flow surrounds with the two side legs of the freely projecting end portion of the spindle formed as a hollow shaft 13 in this semi-longitudinal section.

The winding machine 1 has a control unit 31. The associated electrical lines 32 to 35 are in Fig. 1 shown in dotted lines. The control unit 31 controls the drive 2 via the line 32 to bring about the desired course of the rotary movement 9. To ensure a control, the control unit 31 is supplied with a speed signal of the drive 2 via the line 33. Furthermore, via the control unit 31 via the line 34, the power supply and control of the linear actuator 17, wherein here to enable a control of the control unit 31 via the line 35, a speed signal can be supplied.

In detail II according to Fig. 2 the spindle bearing 10 is formed with a sleeve-like bearing body 36 which is supported by the machine frame 3. On the sleeve-like bearing body 36 are internally supported bearing units 37a, 37b, via which the spindle 8 is mounted relative to the bearing body 36 in a conventional manner.

On the side facing the spool 12, an actuating body 38 is held on the machine frame 3, which forms an actuating surface 39, which is inclined relative to the axis of rotation 11, or a cone-actuating surface 70. The actuating surface 39 or cone actuating surface 70 occurs in the manner explained in more detail below in interaction with an inclined relative to the rotation axis 11 inclined surface 40 or cone inclined surface 69 of the traversing carriage 20, the traversing sleeve 21 and clamping sleeve 22, in the machine frame. 3 facing end region thereof is arranged.

In Fig. 2 Furthermore, it can be seen that the traversing carriage 20 is sealed in the machine frame 3 facing end region relative to the spindle 8 via a sealing unit 68.

Fig. 4 shows the detail IV with the coupling device 19. The coupling device 19 has a cover 41. The lid 41 has two parallel, sleeve-like projections 42, 43. The outer projection 42 is screwed with an external thread in an end-side internal thread of the traversing carriage 20 and the traversing sleeve 21 or clamping sleeve 22. The extension 42 in this case has an inner diameter which is greater than the outer diameter of the Spindle 8. The sleeve-like extension 43 forms with its inner surface 44 a bearing surface for bearing units 45a, 45b. The assigned end region of the actuating rod 15 is supported radially on the bearing units 45a, 45b. The bearing units 45a, 45b are secured in a conventional manner, here via heels, lock nuts and a locking ring, axially on the one hand to the cover 41 and on the other hand relative to the actuating rod 15. The bearing units 45a, 45b in this case form a thrust bearing 46, by means of which the traversing movement 18 can be transmitted from the actuating rod 15 to the traversing carriage 20. In the annular space formed between the sleeve-like projections 42, 43 can in the in Fig. 4 shown position of the graduated here trained end portion of the spindle 8 may be arranged. For the illustrated embodiment, the lid 41 is formed with a through hole through which the mounting and tightening of the shafts nuts is possible. In a manner not shown, the coupling device 19 and the cover 41 may be closed with a closure element closing the through hole of the cover 41, so that in total the traversing carriage 20 and the coupling device 19 in the in Fig. 4 are closed and encapsulated, so that no resulting during the winding process impurities can enter the interior, where they could affect, for example, the function of the storage units 45a, 45b.

In Fig. 5 the trained as a linear actuator 17 actuator 16 is shown in greater detail V. Here a drive drives a pulley of a belt drive 47 back and forth. On the belt of the belt drive 47, a driver 48 is fixed, which in turn is attached to the end portion of the actuating rod 15. Thus, the actuation of the actuator 16 with a reciprocating movement of the belt drive 47 leads to the movement of the actuating rod 15 with the traversing movement 18th

The operation of the winder according to Fig. 1 to 6 is as follows:

On an empty spindle 8 and an empty traversing carriage 20, a bobbin tube 27 is first pushed until it comes to a stop 49 on the front side to the plant. The stop 49 is here formed by a circumferential collar or collar 50 of the traversing carriage 20, the traversing sleeve 21 or the clamping sleeve 22, wherein the collar 50 on the machine frame 3 side facing the inclined surface 40 or cone-inclined surface 69 is formed.

Thereafter, the bobbin clamping device 26 is actuated, whereby a both rotationally fixed and axially secured fixation of the bobbin tube 27 takes place on the traversing carriage 20.

Next, a Spulgut 51 is brought to the bobbin tube 27 that a winding is created. In this case, a known in a known manner catching means for the Spulgut 51 in the field of the winder 1 or the bobbin tube 27 may be provided. During the winding cycle then brought about, the control unit 31 controls the drive 2 and the actuator 16 in a coordinated manner in such a way that when the winding 28 is generated by superimposing the traversing movement 18 and the rotational movement 9, a desired winding image is produced. Fig. 1 and 6 show the traversing carriage 20 and the coil 12 arranged thereon in the two end points of the traversing movement 18, namely Fig. 1 a rear end position with the smallest distance from the machine frame 3 and Fig. 6 a front end position with maximum distance from the machine frame 3. Between these end positions takes place with the traversing movement 18, the movement of the traversing carriage 20 with arranged thereon spool 12 such that a Spulgut 51 is always fed from the same place without the need of using a traversing device with traversing yarn guide wherein, ideally, always a supply of Spulguts 51 is perpendicular to the axis of rotation 11.

Upon completion of the winding 28, the bobbin clamping device 26 is released, so that the removal of the finished wound coil 12 of the traversing carriage 20 is possible. In a manner known per se, a severing of the material to be wiped can take place beforehand. It is possible that the control unit 31 is equipped with control logic, by means of which a targeted supply of Spulguts by appropriate movement of the traversing carriage 20 to a catching device and / or a cutting device. This is preferably done in a range of movement of the actuator 16, which is not in the usual stroke of the traversing movement 18, but outside of it.

For the illustrated embodiment, the control unit 31 is equipped with control logic such that the operation of the bobbin tensioning device 26 is controlled by movement of the control of the actuator 16, to which the actuator 16 is controlled in a position which is outside the usual operating stroke for the traversing movement 18 , In this operating position to generate an actuating force by the actuator 16 is the Sloping surface 40 of the traversing carriage 20 pressed against the machine frame 3 fixed actuating surface 39. Without the generation of this actuation force, the bobbin tube tensioning device 26 is actuated such that the bobbin tube 27 is held firmly on the traversing carriage 20, while the bobbin tube tensioning device 26 is deactivated with generation of the actuating force, so that the bobbin tube 27 slidably pushed onto the traversing carriage 20 or can be deducted from this.

To generate the traversing movement 18, any actuators 16 can be used (otherwise with a corresponding configuration of the winding machine 1). For the in Fig. 7 illustrated embodiment, an electric drive 52 is used, the drive wheel 53 via a traction means 54 drives a driven gear 55, which is rotatably mounted, but axially fixed to the bearing body 36. The output gear 55 forms a spindle nut 56 which forms a spindle drive 58 with a spindle 57. Here, the spindle 57 is formed with the associated end portion of the actuating rod 15 for the illustrated embodiment, which is equipped for this purpose with an external thread, with which the spindle nut 56 is screwed. The movement of the spindle nut 56 caused by the drive 52 thus has the result of the axial movement of the spindle 57 and thus of the actuating rod 15, so that the traversing motion 18 can be generated via the activation of the drive 52.

Fig. 8 shows a further possibility for the design of the actuator 16. Here, an electric drive 59 drives a Kehrgewindewelle 60, wherein in the Kehrgewinde 61 of the Kehrgewindewelle 60 engages a supported by the driver 48 sliding element, whereby a Kehrgewindetrieb 62 is formed for bringing about the traversing movement 18 ,

In the context of the invention, any bobbin clamping devices 26 can be used. For the example used in the preceding figures bobbin clamping device 26 of the traversing carriage 20, here the traversing sleeve 21, as a clamping sleeve 22 is formed, which as an individual part in Fig. 9 is shown. The clamping sleeve 22 forms in an end region of the collar 50, which forms the inclined surface 40 or cone-inclined surface 69 and the stop 49. For the sake of simplicity, further details of the clamping sleeve 22 as the recess for the driver 24, mounting holes for the screwing of the driver 23 with the clamping sleeve 22 u. Ä. Not shown.

In Fig. 9 It can be seen that the clamping sleeve 22 is formed with a slot 63. While in principle the slot 63 can be arranged in any axial region of the clamping sleeve 22, if this axial region has an overlap to the region in which the bobbin 27 is to be stretched, and the slot 63 of any shape with a constant or varying width and any course can take place according to Fig. 9 a slot 22 insert with a front side introduced from the side of the machine frame 3 slot 63. The slot 63 has a first portion 64 which is oriented parallel to the longitudinal or rotational axis 11, and a second portion 65 which extends from the inside End portion of the portion 64 extends in the circumferential direction, so that the two sections 64, 65 are arranged in a development L-shaped. Here, the slot 63 in the region of the sections 64, 65 has a constant and equal width. With the slot 63, a material weakening of the clamping sleeve 22 is provided, so that the clamping sleeve 22 in the vicinity of the slot 63 forms a deformation region 74 which is deformable with a smaller actuating force than would be the case in another axial section of the clamping sleeve 22. If, as explained above, for the actuation of the bobbin clamping device 26, the inclined surface 40 to the actuating surface 39 of the actuator body 38, an actuating force is generated on the inclined surface 40 of the clamping sleeve 22, which presses the collar 50 radially inwardly. This results in an elastic deformation of the clamping sleeve 22 with a reduction in the diameter of the lateral surface 66. By generating the actuating force, which is brought about by the actuator 16, the clamping sleeve 22 is transferred to an elastically deformed state, in which the diameter of the lateral surface 66th the clamping sleeve 22 is slightly smaller than the diameter of the inner surface 67 of the bobbin 27, so that in this actuated state, the bobbin 27 can be pushed onto the clamping sleeve 22 and (with finished wound coil 12) thereof can be deducted. If, however, the actuator 16 is actuated such that the collar 50 is removed from the actuator body 38, eliminates the actuation force and it comes to elastic expansion of the clamping sleeve, whereby the lateral surface 66 of the clamping sleeve 22 is pressed from the inside against the inner surface 67 of the bobbin 27 and a transmission of the rotary motion 9 and the traversing movement 18 can take place. Preferably, the actuating surface 39 and the inclined surface 40 are formed as a cone-actuating surface 70 and cone-inclined surface 69, wherein preferably the opening angle of the cone is greater than a self-locking angle.

• in Umfangsrichtung umlaufend ausgebildet sein und über den gesamten Umfang an die Innenfläche 67 der Spulenhülse angepresst werden oder
• lediglich in einem Teilumfangsbereich gebildet sein, welcher beispielsweise durch den Schlitz 63 begrenzt sein kann, wobei auch (u. U. mit mehreren Schlitzen 63) mehrere Kontaktflächen 73 in Umfangsrichtung verteilt angeordnet sein können.

The clamping sleeve 22 has an axial section 71, in which the lateral surface 66 has an outer diameter such that a clearance or a fitting fit to the inner surface 67 of the coil sleeve 27 results. In at least one further axial section 72, which is arranged directly adjacent to the inclined surface 40 and / or the collar 50, the lateral surface 66 of the clamping sleeve 22 has an outer diameter which is slightly larger in the unloaded state than the inner diameter of the inner surface 67 of the coil sleeve 27, so that results in a tensioning of the bobbin tube 27 on the clamping sleeve 22 without the action of the actuating force in the region of the inclined surface 40. In this axial section 72, the lateral surface 66 of the clamping sleeve 22 forms a contact surface 73, which is pressed in the clamping position against the inner surface 67 of the coil sleeve 27. Here, the contact surface 73 in the axial section 72nd

• be formed circumferentially circumferentially and be pressed over the entire circumference of the inner surface 67 of the bobbin or
• may be formed only in a partial peripheral area, which may be limited, for example, by the slot 63, wherein (u., With multiple slots 63) a plurality of contact surfaces 73 may be arranged distributed in the circumferential direction.

For the illustrated embodiment, the slot 63 separates a shell-shaped or web-shaped, oriented in the circumferential direction portion of the clamping sleeve 22 from. Similar to a curved, circumferentially oriented bending beam generating the actuating force on the inclined surface 40, this portion can be bent radially inwards about an axis oriented parallel to the longitudinal axis 11, a deformation region 74 in which the bending takes place predominantly in the connection region or "clamping region "of the separated shell-shaped portion is arranged, while the contact surface 73 is formed primarily in the portion 64 of the slot 63 facing the end portion of the separated cup-shaped portion. For one of the many possible alternative embodiments, a plurality of slots 63 distributed over the circumference are equipped exclusively with the axial section 64 (ie without sections 65). Between adjacent slots 63 are then formed by the clamping sleeve 22 parallel to the longitudinal axis 11 extending spring arms which are connected in one end portion of the axial portion 71, while the collar 50 in the other end, each with inclined surfaces 40 forms. In this case, the generation of the actuating force on the inclined surface 40 causes the spring arms to be bent about a circumferentially oriented axis. Any other use the clamping sleeve 11 in the axial section 72 for generating the radial clamping force or removal thereof are also possible.

Fig. 10 shows the interaction of the clamping sleeve 22 with the bobbin 27. The clamping sleeve 22 forms the lateral surface 66, which is pressed against the inner surface 67 of the bobbin sleeve 27 without actuation.

The Spulgut 51 are, for example, threads, yarns, tapes, wires, strands, monofilaments, multifilaments u. Ä. It is possible that the control unit 31 is equipped with control logic such that a removal of the finished wound coil 2 and a sliding of a new bobbin sleeve 27 is made possible by the traversing carriage 20 is moved to a removal position outside the usual stroke for the traversing movement 18 ,

The present winding machine 1 can be designed with regard to further aspects according to the usual winding machines. Thus, for example, use of the measures according to the invention for winding machines can take place, which have two or more spindle units which are held, for example, on a turret and wherein a spindle unit is alternately brought into a change position, while the other spindle unit is in a winding position. Also possible is the use of the invention for a winder, in which a plurality of coils are arranged one behind the other on a spindle and a common traversing carriage or several traversing carriages and are wound simultaneously. It is also possible that in each case a plurality of concentrically arranged coils are generated on two spindles.

For the illustrated embodiment, the operation of the traversing carriage 20 takes place from the free end portion of the spindle, including the passage of traversing movement by the spindle by means of the actuating rod. Alternatively, it is possible that the actuating rod extends only to the axial region in which the coil 12 is to be arranged, and engages with a radially oriented pin, which extends through an elongated slot of the spindle in a circumferential groove of the traversing carriage. Finally, it is also possible that the operation of the traversing carriage 20 takes place from the side facing the machine frame 3 and radially outward from the spindle.

It is also possible that a plurality of slots 63 of any and the same or different shape are provided on the clamping sleeve 22.

It is possible that by the radial clamping of the lateral surface 66 of the clamping sleeve 22 with the inner surface 67 of the bobbin tube 27, a frictional connection is brought about, which avoids an axial relative movement of the bobbin 27, possibly with trained thereon winding 28, relative to the clamping sleeve 22. Furthermore, by means of this frictional engagement, the transmission of the drive movement from the clamping sleeve 22 to the coil sleeve 27 can take place. Finally, a positional fixation of the bobbin tube 27, possibly with winding 28 formed thereon, to the clamping sleeve 22 can take place with coaxial alignment and centering of the bobbin tube 27 on the clamping sleeve 22.

For a different embodiment, in addition to the frictional engagement between the clamping sleeve 22 and the bobbin tube 27, a form fit in the circumferential direction can also be used in order to transmit the drive movement from the clamping sleeve 22 to the bobbin tube 27. To name just one example, the bobbin sleeve 27 can have at least one axial slot, a recess or a groove in the end region facing the machine frame 3, in which (n) a rib, a projection or a radially oriented pin of the clamping sleeve 22 with a sliding of the bobbin sleeve 27 engages the clamping sleeve 22. About the connection between the slot, recess or groove and the projection, the rib or the pin can then be carried out the transmission of the drive movement of the clamping sleeve 22 on the bobbin 27. Conversely, the bobbin tube 27 may have a radially inwardly oriented projection, a rib or a pin, which then enters into a recess, a groove or a slot of the clamping sleeve 22. In the two cases mentioned then the frictional engagement between the clamping sleeve 22 and the bobbin tube 27 exclusively or primarily responsible for the axial fixation of the bobbin tube 27 on the clamping sleeve 22 and / or the centering and specification of the coaxial position of the coil sleeve 27 on the clamping sleeve 22. It is understood that a positive connection and a frictional connection for can complement the transmission of torque. U. U. for the transmission of torque via a form fit the application of the bobbin tube 27 on the clamping sleeve 22 for a given circumferential orientation of the bobbin tube 27 relative to the clamping sleeve 22nd

The diameter, the wall thickness, the material and the rigidity of the clamping sleeve 22 are preferably selected such that with the actuation of the clamping sleeve 22 has a radial Deformation results, resulting in a change in the radius of the clamping sleeve 22 in the region of the contact surface 73 in the range of 0.2 mm to 35.0 mm, in particular 0.5 mm to 20.0 mm or 0.5 mm to 15.0 mm results. Here, the lateral surface 66 in the area of the contact surface 73 in the actuated state preferably has a radius which corresponds to the nominal dimension of the radius of the inner surface 67 of the bobbin tube 27 (possibly with the formation of a joining play), while in the non-actuated state without the bobbin sleeve 27 arranged thereon the lateral surface 66 of the clamping sleeve 22 with respect to the nominal size of the bobbin sleeve 27 has an excess of 0.5 mm to 20 mm. The frictionally transmittable via the clamping sleeve 22 torque is significantly determined by the material and the thickness of the clamping sleeve 22 and the bobbin 27. It is possible that the friction conditions between the coil sleeve 27 and clamping sleeve 22 are influenced by a suitable, friction-increasing coating of the lateral surface 66 and / or the inner surface 67, for example with a coating of rubber at least in the region of the contact surface 73. It is possible that the Spool sleeve 27 is made of cardboard, plastic, aluminum or steel. The clamping sleeve 22 is preferably made of steel, aluminum or plastic. The frictionally transferable from the clamping sleeve 22 to the coil sleeve 27 torque is preferably greater than 100 Nm.
