The bobbin 8 causes a collision of the outer peripheral surfaces of the bobbins 6 and 8 with respect to the winding device 1 in which the interval 36 between the rotary shafts 18 and 19 of the bobbins 6 and 8 is narrow, Before reaching the critical diameter, the fully wound bobbin 6 must be quickly removed.
According to the present invention, the bobbin 6, which is completely wound before or during the winding process of the bobbin 8, is moved by the position moving device 23 past the position movement path 25, The axial extensions 14, 15 of the first and second axially extending portions 14, 15 do not include overlapping portions, but rather have an interval 26. In this way, the collision of the bobbins 6, 8 with the increase of the diameter of the bobbin 8 can be prevented, so that a compact structure in which the intervals of the spindles 4, 5 are narrower becomes possible, More time is given to remove the bobbin 6.

Description

[0001] WINDING MACHINE [0002]

The present invention relates to a winding device on which at least two spindles are alternately wound with continuous winding material, in particular yarns, wires, bands, twists and the like, to produce a bobbin. The present invention also relates to a method for driving such a winding device.

For example, a winding device is known in which winding material is continuously supplied to a winding device by a continuous manufacturing process, and thereafter wound on a spindle (with or without a sleeve) to produce a bobbin. The bobbin can then be transferred and used in subsequent processes for further processing of the wound material. The winding of the bobbin takes place on one spindle which can be driven to generate the winding motion itself. Alternatively, it is known that by the frictional drive, in particular the rotational motion of the bobbin by the radially compressed drive roller on the outer circumferential surface of the bobbin can occur. During winding, the winding material is reciprocated in the longitudinal direction of the spindle by a traversing device, wherein the traverse device is located slightly forward or upstream of the bobbin in the path of the winding material. The three-dimensional bobbin whose diameter is expanded in the winding path is formed by overlapping between the rotation operation and the traverse operation which are adjusted by using the control unit.

There is also known an application of a winding device which has at least two spindles and in which such spindles can be used alternately in the working position for bobbin winding. A single traverse device can be specified for winding of the bobbin on two spindles. When the winding material has reached a certain amount in the spindle being used for winding, i.e. the spindle in the working position, the spindle moves to the rest position. Automatically or by user's operation, the winding material to be fed from another spindle in the working position or from a sleeve disposed on the other spindle is handed over. After this position change, the fully wound bobbin is manually or automatically removed from the first spindle in the rest position. At least two spindles are often rotatably supported on a swivel or revolver for the transfer of the spindle between the working position and the rest position, wherein the axis of rotation of the spindle and the revolver are oriented parallel to one another. As the spindle rotates, the position of the spindle can be changed alternately.

A corresponding winding device is known from patent DE 102 23 484 B4 . The patent is for allowing the winding material to be transferred from the first spindle to the second spindle for the exchange process. At this time, the fixed winding and the storage winding are wound before the start of the inherent winding process outside the hypothetical width. If the traverse device comprises a reverse threaded axis, the traverse thread guide of the traverse device may be disposed outside the hypothetical width without a constituently consuming additional treatment for forming the groove of the reverse threaded axis. The patent teaches that the traverse device is displaced parallel to the longitudinal axis and the axis of rotation of the spindle by means of a position shifting device so that the winding material can be placed on the spindle or sleeve outside the said width and the stationary windings and the storage windings can be formed And the position of the robot is moved in such a manner as to be moved. The position-shifting device used here refers to a pneumatically actuated piston / cylinder-unit, which can be pneumatically actuated at a time when the valve and sub-control unit are free to arbitrarily select. Before the fully wound bobbin is taken out of the winding device, the fully wound bobbin is in the rest position and the bobbin in which the diameter is to be produced is in the working position. In order for the completely wound bobbin in the rest position to be able to be taken out later from the winding device even if another bobbin is completely wound in the working position, the mutual spacing of the bobbins must correspond at least to the diameter of the fully wound bobbin, The circumferential surface of the bobbin whose diameter increases in the circumferential direction is adjacent to the outer circumferential surface of the bobbin completely wound at the rest position is excluded. If the spacing between the spindles is chosen to be smaller, this means that the fully wound bobbin in the rest position must be taken out by the user automatically or automatically, ie faster, that is, the bobbin in the working position must be taken out before it is fully wound. If the fully wound bobbin is not ejected in time, the two bobbins collide and the winding device stops. Therefore, in consideration of the gap between the two spindles in the constitutional formation of the winding device,

On the one hand, the spacing of the spindles must be kept as small as possible to reduce the size of the winding device;

However, on the other hand, the spacing of the spindles should be as large as possible and should be provided as much as possible so that the bobbins can be completely wound without collision of the bobbins,

A conflicting goal is given.

As the supply speed of the winding material increases, the problem of the conflicting target becomes more serious as the completion speed of the bobbin becomes faster.

A problem underlying the present invention is to propose a winding device which provides a sufficient time for a take-out of a fully wound bobbin (and, in some cases, the installation of an empty sleeve) with a compact configuration The risk of collision on the outer circumferential surface of the bobbin is reduced. Further, a problem underlying the present invention is to propose a driving method of the winding device which is improved in relation to the replacement step and the taking-out step.

The object of the invention is solved according to the invention by means of a winding device comprising the features of claim 1 which are independent claims. Other embodiments of the winding device according to the invention are derived in accordance with the features of the dependent claims 2 to 10. Further, a problem underlying the present invention is solved by a method including the features of the eleventh aspect. Other implementations of the method according to the invention are derived in accordance with the dependent claims 12 to 20.

The present invention firstly resolves that the predetermined time dependent on the feed rate for the take-out of the bobbin completely wound in the rest position of the winding device depends on the spacing of the spindles. This is made possible by arranging the bobbins in the take-out position of the fully wound bobbin caused by the position shifting device without overlapping the axial regions of the bobbin according to the invention. At this time it is entirely possible that the end regions of the sleeve projecting from the wind-up material-windings comprise a certain degree of overlap, and that the wind-up material-windings of the bobbin do not necessarily contain any overlap. Thus, according to the invention, on one hand the fully wound bobbin and on the other hand the bobbin being produced is "offset" in the axial direction, thereby completely blocking the possibility of collision of the two bobbins. Alternatively or additionally to the advantage of collision avoidance, it may be advantageous for the take-off process that the fully wound bobbin is displaced by the position shifting device, a longer time is provided and / Because the bobbin is moved from the main working level of the winding device for winding of the fully wound bobbin by means of the positional movement and in this position the bobbin is accessible to the user by a better or automatic extraction device depending on the situation and / The risk is reduced. In addition, the bobbin may pass some path for taking out in the direction of the already storing means or the conveying means by the position movement.

In another embodiment of the invention, the winding material is caught and held on one spindle, in particular on the top of the spindle itself or on a sleeve extending through the spindle in the working position of the spindle. At this time, an embodiment in which the working position, that is, the position of the bobbin during the winding process, is changed corresponding to the diameter increasing during the winding process can be considered from the prior art.

At the same time as the bobbin is caught and / or wound on the spindle in the working position, on the other spindles in the rest position, the fully wound bobbin is taken out of the winding apparatus and can be performed manually or at least partially automated by the user. The spindle may alternately be in the working position and the rest position, in which case it is entirely possible that an additional position, for example a maintenance position or an intermediate position, is temporarily employed.

By the position moving device, the fully wound bobbin can be moved in the direction of the rotation axis of the bobbin, so that the fully wound bobbin is transferred from the winding position to the take-out position. The position moving path of the position shifting device is larger than the extending portion of the bobbin in the direction of the rotation axis of the bobbin, that is, larger than the mounting width of the bobbin.

There are various methods for ensuring the necessary position movement path of the fully wound bobbin and for constituting the position moving device. According to a particular embodiment of the invention, the position shifting device moves the bobbin against the spindle. For example, the bobbin may have a degree of freedom in the direction of the axis of rotation of the bobbin opposite the spindle. This degree of freedom may be fixed during the winding process of the bobbin, while the degree of freedom is utilized by the position shifting device to cause the take-out position, which is the case when the bobbin moves relative to the spindle. In particular, the bobbin slides along the outer peripheral surface of the spindle.

For an alternative embodiment of the present invention, the position shifting device moves the bobbin with the spindle, where the spindle itself has a degree of freedom in the direction of the longitudinal axis or axis of rotation of the spindle against the winding device. For example, a spindle with such a degree of freedom can be supported against a rotating plate or other formed revolver, and the degree of freedom is then utilized by the position shifting device. A type of spindle telescope is also possible.

Basically, the use of any position moving device can be considered. In an embodiment of the present invention, an axial actuator actuatable by the control unit is used, and the operating path of the actuator preferably corresponds to the positional travel path of the bobbin causing the take-off position. For example, as a pneumatic piston / cylinder actuator, an actuator formed as an actuator including a subsidiary valve and an associated electrical control unit may be used, as described in DE 102 23 484 B4 (for other uses, of course) , Is just one example of a number of different implementations for location mobile devices.

In contrast to the frame fixed to the housing of the winding device, according to the invention, the spindle moves on the one hand between the working position and the rest position in the transverse plane with respect to the axis of rotation of the bobbin or spindle, (Hereinafter referred to as " revolver "). On the other hand, by the position shifting device, the fully wound bobbin is shifted in the direction from the winding position to the take-out position, the direction being oriented parallel to the direction of rotation of the bobbin or spindle. The above-described two operations can be controlled separately and in succession from each other in terms of time, and the position shifting operation can be performed before or after the rotation of the rotary disk or the revolver. Both operations are preferably performed at least partially at the same time so that time can be saved even when the operating speed and the operating acceleration are low.

Further, according to the present invention, the position shifting device is operable in such a manner that the movement is controlled in accordance with the rotation operation of the revolver. The position shifting device can be controlled according to the time condition by the rotation angle sensor for sensing the rotation of the revolver or the switch operated by the rotation of the revolver. Similarly, it can be considered that a control signal for rotation of the revolver is simultaneously used to control the position moving device. As long as the additional actuator for forming the position shifting device is completely omitted, the operation control by the rotating operation of the revolver can be performed while the position shifting operation is directly combined with the rotating operation of the revolver. This can be done by mechanical coupling, for example by branching the mechanical drive output of a common drive assembly for the revolver and the position shifting device. This includes an embodiment in which the rotating motion of the revolver is converted into a positioning operation by a curved disk or cam disk so that the position shifting device is formed of a curved disk or a cam disk by mechanical coupling.

In particular, in an embodiment in which the bobbin is moved relative to the spindle by a position shifting device, for another embodiment of the winding device, at a take-off position in which the bobbins are disposed without overlap of the axial regions of the bobbins by the position- It is proposed that the accessory spindle extends only partially through said fully wound bobbin. An extended portion of the spindle passing through the bobbin defines a take-out path for taking out the bobbin from the spindle. Therefore, if the extension portion of the spindle passing through the fully wound bobbin is reduced, the cost of taking out can also be reduced.

In another embodiment of the present invention, the position shifting device can be used in a multifunctional manner: in this embodiment, only the driving position change of the bobbin from the winding position to the take-out position is not possible by the position shifting device. Rather, the bobbin may be moved by the position shifting device to a driving position (different from the winding position, potential maintenance position and / or take-out position, as the case may be) And / or the capture device. Briefly, for example, by means of a position shifting device, the winding material can be pressed against a knife formed as a cutting device upstream of the circumference of a fully wound bobbin, whereby the winding material is cut. This is correspondingly applied also to the trapping device used when the winding material is caught in the region of the spindle or in the region of the bobbin to be rewound. Alternatively, or in addition, it is also possible to move to a drive position in which the stationary wind-up and / or the take-up wind-up is formed by the position moving device. This embodiment is based on a solution according to DE 102 23 484 B4, in which a traverse device has to be run for the formation of a fixed winding or a storage winding. While using suitable actuators depending on the situation, a similar effect can be achieved using a position shifting device as the winding material along with the bobbin position movement can be accompanied by the axial region of the spindle where the new bobbin is to be wound to be. In the axial region, the production of fixed winding or stored winding can be performed. See DE 102 23 484 B4 for more details on the basic formation of fixed and retentive coils and appropriate control procedures for them.

In the method according to the invention, the fully wound bobbin is moved to the take-out position by the position shifting device, the axial area of the fully wound bobbin at the take-off position is the part overlapping the axial area of the bobbin to be wound on the other spindle There is no.

The advantages of the features mentioned in the introductory part of the description and the combination of the plurality of features are exemplary only and the advantages do not necessarily have to be achieved by the embodiments according to the invention but alternatively or additionally, Can be exercised.

Hereinafter, the present invention will be described and explained in more detail with reference to the drawings showing preferred embodiments.

Figure 3 is a highly schematic plan view of a winding device according to the invention; At this time, the fully wound bobbin is in the maintenance position.

5 is a block circuit diagram that is greatly simplified for the method according to the present invention;

Fig. 1 and Fig. 2 schematically show the winding device 1. Fig. The winding device 1 comprises a rotary disk or revolver 2 which is adapted to rotate about a rotation axis oriented perpendicular to the plane of the drawing according to figure 1 against the support structure 3 of the winding device 1, And can be rotated by the drive assembly. The revolver 2 supports the spindles 4 and 5 and the axis of rotation and the longitudinal axes 18 and 19 of the spindle are likewise oriented perpendicular to the plane of the drawing according to figure 1 and are equally spaced diagonally, 2 on the opposite sides of the rotation axis. On the spindle 4, a fully wound bobbin 6 is preferably located including the sleeve 7. The fully wound bobbin (6) has a diameter (D).

The bobbin 8 is located on the spindle 5 and is likewise located, including the sleeve 9, and the diameter d increases during production. The supplied wrapping material 10 is fed to the bobbin 8 by the traverse device 11. [ The distance between the longitudinal axis of the spindle 5 and the axis of rotation of the traverse device 11 from the axis of rotation may vary depending on the diameter d which is magnified throughout the winding process in a manner known per se, 5) have an appropriate degree of freedom for relative movement in the plane of the drawing according to Fig. 1, the bobbin 6 is located in the rest position 12, and in the rest position the bobbin 6 must be removed from the spindle 4 by the user or at least partially automated. In some cases, a new sleeve 7 can be stuck on the spindle 4 in the rest position 12. [ On the other hand, the bobbin 8 is located in the working position 13 and the winding material 10 in the working position is fitted by the spindle 5 or, if appropriate, the sleeve 9 and the storage and / / RTI > is produced / generated and the unique winding process is carried out with increasing diameter (d). When the bobbin 8 is fully wound and becomes d = D, the revolver 2 rotates 180 degrees about its rotation axis so that the spindle 5 is in the rest position 12, 6) take-off spindle 4 can be moved to the working position 13 and a new winding process can be started.

It is apparent from Fig. 1 that the diameter d is increased until the outer circumferential surface of the bobbin 8 is adjacent to the outer circumferential surface of the bobbin 6 while the interval 21 of the outer circumferential surfaces of the bobbins 6, It can be confirmed that it is reduced. This will result in stopping or stopping the winding process. Accordingly, the bobbin 6 must be removed from the spindle 4 before the diameter d is increased and the gap 21 is reduced to zero. 2, each of the bobbins 6 and 8 includes axially extending portions 14 and 15, which recognize that the installation width of the winding material and the traverse path of the traverse device 11 correspond to each other can do. 2 shows that the sleeves 7 and 9 used here project from the bobbins 6 and 8 on the front side and the lengths of the sleeves 7 and 9 are larger than the axial extension portions 4 and 15 . The front sides 16 and 17 of the bobbins 6 and 8 are disposed in the same vertical plane oriented transversely with respect to the rotational axes 18 and 19 of the bobbins 6 and 8 without deviating from each other, 8 comprise overlapping portions 20 which conform to the axial extensions 14, 15 according to the prior art. The spacing 21 of the bobbins 6,8 is located in a plane passing through the longitudinal axis of the spindles 4,5. The axial overlap 20 is led out through the protrusions of the axially extending portions 14, 15 to the longitudinal or rotational axes 18, 19 of the bobbins 6, 8 in particular.

3 , the fully wound bobbin 6 is in the resting position 12, whereas the bobbin 8 is in the rest position 12, while in the embodiment according to the invention, And is being generated in the work position 13. Here again, the bobbins 6 and 8 include the overlapping portion 20 because both of the bobbins 6 and 8 are in the winding position 22, that is, arranged in the same vertical plane. At this time, the winding positions 22 indicate the relative positions of the bobbins 6, 8 with respect to the attached spindles 4, 5 or the supporting structure 3 or the revolver 2, respectively. In the rest position 12 and the winding position 22 of the bobbin 6 according to Fig. 3, the fully wound bobbin 6 is not yet taken out. Rather, before the interval 21 between the outer circumferential surfaces of the bobbins 6, 8 is "exhausted" due to the increase in diameter d, the winding position 22 is also rotated by the operation of the position moving device 23 The bobbin 6 including the sleeve 7 is moved in the axial direction from the winding position 22 in the axial direction against the spindle 4, To the take-out position (24). At this time the locating path 25 is such that the axially extending portions 14 and 15 of the bobbins 6 and 8 no longer include the overlapping portion 20 but are formed on the longitudinal or rotational axes 18 and 19, Are selected to have an interval (26) between them when projecting the direction extension parts (14, 15). The position moving path 25 of the position moving device 23 is larger than the axial extending portions 14 and 15 of the bobbins 6 and 8. [ It can be seen in Figure 4 that the collision between the bobbins 6, 8 is reliably prevented irrespective of the diameter d of the bobbin 8 to be wound. The positional movement of the bobbin 6 over the locating path 25 may start at any point in time, for example, at the beginning of the winding process for the bobbin 8 or during the winding process of the bobbin 8 . The bobbin 6 may be taken out from the winding position 22 shown in Fig. 3 by the user at ordinary times without the positional movement by the position moving device 23 in the normal winding device 1. In this case, the operation of the position shifting device 23 is such that when the diameter d of the bobbin 8 reaches or exceeds the critical diameter d _GRENZ , the bobbin 6 has not yet been taken out of the spindle 4 This is done only when the sound is recognized automatically. In this case, the position indicated as "take-out position 22" according to Fig. 4 is a kind of safety position.

According to the illustrated embodiment, the position shifting device 23 according to the present invention refers to a stamp 27 which is movable under the control of the actuator. For example, a pneumatic piston / cylinder-unit may be used for operation of the stamp 27, at which time the unit may operate against a spring such that the automatic return of the stamp 27 by the exhaust of the piston / cylinder- . Likewise, if a new sleeve 7 is pushed onto the spindle 4, it is also possible for the stamp 27 to be pushed back for the evacuated piston / cylinder unit. 4, the front side of the stamp 27, for example the front side including the press-in plate 37, acts on the front side of the sleeve 7 so that the bobbin 6 is moved to the position movement path 4 Let's move it. Likewise, the corresponding front side of the stamp 27 can act directly on the winding of the bobbin 6, especially when the bobbin 6 is formed without the sleeve 7. [ The bobbin 6 or the sleeve 7 can be fixed axially and / or radially on the spindle 4 in the working position 13 and in the transfer from the working position 13 to the rest position 12, At this time, the corresponding axial and / or radial fixation must be released before actuation of the position shifting device 23.

2 and 3, it can be seen that the spindles 4, 5 are formed according to the invention longer than in the prior art: as can be seen in figure 3, the bobbins 6, Project from the bobbin 6, 8 from the sleeve 7, 9 here at a predetermined length 28 from the position 22. This length 28 can be adjusted according to circumstances. This length 28 is preferably between 50% and 100% of the axial extensions 14,15 of the bobbins 6,8. The bobbins 6 and 8 are supported by the spindles immediately at the take-out position 24 without a corner angle with a minimum length 28 corresponding to 50% of the axial extension parts 14 and 15. If the length 28 is short, the path that the bobbin 6 must move in the direction of the rotational axis 18 when taken out by the user or automatically is reduced. The length 28 may be 60%, 70%, 80%, 90% or 100% of the axial extensions 14,15. Overall, length 28 may be longer than the length described above.

The spacing 36 of the rotating shafts 18, 19, i.e. the spacing between the longitudinal axes of the spindles 4, 5 shown in the projection view in Figures 3 and 4, is preferably less than the diameter D. [ The spacing 36 of the rotating shafts 18 and 19 may be 60%, 70%, 80%, 90% or 100% of the diameter D, The present invention also includes an embodiment in which the distance between the rotating shafts 18 and 19 is larger than the diameter D, wherein the embodiment according to the present invention increases the handling space, Preparation and partial implementation becomes possible.

Figure 5 shows an exemplary flow chart of a method according to the invention:

At step 29 the complete winding of the bobbin 6 is first performed at the working position 13 on the spindle 4 with the bobbin 6 at the winding position 22 against the spindle 4.

Subsequently, in step 30 the revolver 2 rotates by an angle of 180 degrees until the spindle 4 is in the rest position 12, as shown in figure 3 basically, 6 are at the winding position 22 against the spindle 4. [ The winding material 10 is fed to the sleeve 9 located at or above the spindle 5 in the working position 13 and in the working position the winding material 10 may be captured by a suitable trapping device. Fixed coils and / or stored coils may be produced to prepare a unique winding process.

Finally, at step 31 the wound material 10 is cut.

In a subsequent step 32, the winding of the bobbin 8 at the working position is performed, at which time the bobbin 8 is in the winding position 22 against the spindle 5. The braking of the bobbin 6 can be performed on the spindle 4 in parallel to the winding of the bobbin 8.

Steps 29 to 32 correspond to the known method steps for this during the replacement process of the winding device 1.

According to the invention, a complementary step 33 is used in which the bobbin 6 in the rest position 12 is moved from the retracted position 22 to the take-out position 24 And the overlapping portion 20 of the axially extending portions 14, 15 is removed at the take-out position.

The automatic operation of the position moving device 34 by the control unit of the winding device 1 in step 33 may be performed in step 34. [ In step 35 the bobbin 6 may be taken off the spindle 4 and the partial take-off may then be carried out by the operation of the position shifting device 23 for the dimensioning of the length 28, Lt; / RTI > (33, 34) is at least partially temporally discrete or continuously during at least one of the steps (30-32) using different alternative alternatives or cumulatively different specification branches indicated by dashed lines in Figure 5 It is implied that it can be performed. For example, the upper dashed branch may imply that the actuation of the position shifting device 23 in step 34 (at least in part) may already be performed during the rotation of the revolver 2 in step 30. Likewise, the operation of the position shifting device 23 corresponding to the intermediate broken line branching portion is performed simultaneously with the winding preparation of the bobbin 8, that is, the feeding of the yarn, the installation of the fixed winding material or the retracted winding material, . It is also possible to take out the partial operation of the position moving device 23 at step 34 and / or take out at step 53 while the bobbin 8 is being wound.

Each spindle 4, 5 can provide its own attached locating device 23. The two locating devices 23 can be supported in the revolver 2 and rotated together with the revolver. If a single positioning device 23 is designated for the two spindles 4 and 5, manufacturing costs can be reduced. In this case, for example, the position shifting device 23 can be supported in the support structure 3 at such a point that the spindles 4, 5 to be taken out of the bobbin can be moved by the rotation of the revolver 2 .

If the position-shifting device is formed of a pneumatically-acting cylinder, such a cylinder can perform dual functions, allowing pneumatic return of the position-shifting device 23. [

The fixation of the bobbin or sleeve on the spindle can be done in a force-wise manner by a worm coil spring which is extendable in the radial direction and surrounds the spindle, and the worm- Which is pressed against the sleeve, thereby causing a rotational axial fixation. The worm coil spring is disposed in the V-shaped groove of the spindle, wherein the V-shaped contour of the groove forms a wedge-shaped inclined surface. The helical spring pushes the worm coil spring outwardly along the inclined surface, thereby expanding in the radial direction. The fixation is pneumatically released, for example, by an actuator, which can be placed directly below the position shifter 23, reacting against the force of the helical spring.

The ratio of the diameter D to the spacing 36 is preferably in the range of 0.7 to 0.9, preferably in the range of 0.75 to 0.85. For example, the exact ratio may be 0.80. This implies that collision may occur when a full bobbin is not taken out, for example at 1/5 of the winding process, in relation to the windable volume and hence the time until the collision takes place.

As an example (the present invention is not limited to this), the distance on the front side of the spindle 4 from the front side 16 of the bobbin 6 to the axial side 14 of the fully wound bobbin 6, Can be 0.7 to 0.8, for example 0.73. The ratio of the length 28 to the axial extension 14 of the fully wound bobbin 6 may be, for example, from 0.6 to 0.7, in particular 0.66. It is clear that entirely different ratios are possible within the scope of the present invention.

Preferably, the operation of the position shifting device 23 is performed only after the complete bobbin 6 is stopped by a suitable braking device. However, the position shifting device 23 can be already operated when the complete bobbin 6 is still rotating. To this end, the position shifting device 23 may be integrated in the spindle itself, i.e. it may be advantageous for the rotating spindle or a part of the spindle to move in the axial direction.
