Description
[0001] Winding device and method for winding a component by means of a wire and winding machine
[0002] The invention relates to a winding device and a method for winding a component by means of a wire as well as a winding machine.
[0003] background
[0004] To optimize the compactness of components to be wound, such as stators, it can be advantageous to arrange connecting wires in a delta series connection or star series connection opposite one connection side for U / V / W. This reduces wire crossings and generally prevents wire accumulation. Since a needle carrier inserted from one side must then be able to deposit wires on the outer diameter of the stator on the opposite side, increased degrees of freedom for winding nozzles can be advantageous.
[0005] In this context, document DE 102004 028 566 A1 relates to a winding device comprising a holder with a parallelogram guide for the winding needle for selectively adjusting various working positions. In order to realize a pivot axis during the pivoting movement of the winding needle that coincides with the outlet opening on the winding needle and thus enables the working position to be changed without affecting the wire tension and the wire path, two lever arms of the parallelogram guide are connected by two pivot elements designed as pivot plates, with a pivot axis of the pivot element being pivotably mounted transversely to a longitudinal axis of the holder.By initiating the parallel displacement of the two parallel lever arms of the parallelogram guide by a common drive with a push rod, a transverse displacement of the parallelogram guide is simultaneously achieved, eliminating the need for additional adjustment devices. Swivel angle ranges of up to 90° can be achieved.
[0006] In the document DE 10 2011 008 662 A1, a needle winding system for winding carriers to be wound, in particular stators, armatures or rotors of electric motors with distributed winding, comprises a winding head that is translationally movable in the longitudinal direction and in the transverse direction, furthermore a needle carrier system with a wire outlet nozzle and a wire guide.
[0007] Document US 10944311 B2 discloses a nozzle rotating device comprising a nozzle unit including a nozzle for emitting a wire from a tip end thereof and a nozzle holder for holding the nozzle, the nozzle unit rotatably supporting the nozzle holder, and a nozzle holder driving member provided integrally with the nozzle unit and moved in the nozzle unit to rotate the nozzle holder.
[0008] Document JP 2011 - 004477 A describes another method for winding a wire material. A nozzle holder, a nozzle rotating unit, and corresponding devices and methods are disclosed in document JP 2003 - 169 455 A.
[0009] Summary
[0010] The object of the invention is to provide a winding device, a method and a winding machine with which the winding of a component by means of a wire can be accomplished in a more efficient and accelerated manner.
[0011] The object is achieved by means of the winding device and the method for winding a component using a wire, as well as the winding machine according to the independent claims. Further embodiments are the subject of dependent subclaims.
[0012] According to one aspect, a winding device for winding (a component) using a wire comprises the following: a fixed bearing element, a switching element, a pivot arm, a pivot lever, and an outlet element with an outlet opening for a wire. The switching element is pivotally (rotatably) connected to the fixed bearing element at a first switching element pivot point. The switching element is pivotally connected to the pivot arm at a second switching element pivot point and pivotally connected to the pivot lever at a third switching element pivot point, which is spaced apart from the second switching element pivot point, such that when the switching element is pivoted, the pivot arm and the pivot lever are pivoted (moved) while each retaining their spatial orientation. The pivot arm and the pivot lever are pivoted in different pivot planes.The outlet element is pivotally connected to the pivot arm at a first outlet element pivot point and pivotally connected to the pivot lever at a second outlet element pivot point, which is spaced from the first outlet element pivot point, such that when pivoting (moving) the pivot arm and the pivot lever, a center point of the outlet opening is (essentially) stationary with respect to the fixed bearing element.
[0013] According to a further aspect, a winding machine is provided, comprising a plurality of winding devices and (at least) one central drive, wherein respective switching elements of the winding devices are mechanically coupled to one another and can be driven jointly by the (at least one) central drive.
[0014] According to a further aspect, a method for winding (a component) by means of a wire is provided, which comprises the following steps:
[0015] - Provision of a winding device, a wire and a component to be wound,
[0016] - Winding the component by means of the wire which is fed via an outlet opening of the winding device, wherein a center point of the outlet opening is (essentially) stationary at a winding position with respect to a fixed bearing element of the winding device during winding.
[0017] With the winding device according to the invention, increased outlet element pivot angle ranges can be achieved while maintaining a constant spatial position of the outlet opening, thus enabling a higher-quality wire laying movement. The (essentially) spatial constancy / stationary stability ensures that no wire is pulled off during the pivoting process, nor does an excess wire arise, which would have to be compensated for, for example, by additional movements of the winding device. By eliminating such additional movements, a reduced process time for wire winding can be achieved.
[0018] Furthermore, pivoting can be performed continuously or in several fixed working positions, and can be carried out by servomotor or pneumatic means. Stators can be advantageously wound with distributed windings, as well as on the top and bottom sides. The winding device also enables large pivot angle ranges. Finally, several winding devices can be mechanically coupled on the drive side and operated jointly with a single central drive.
[0019] Furthermore, an arrangement for winding by means of a wire can be provided, which comprises the winding device, a wire, and a component to be wound. The wire can be guided through the outlet opening. The wire can, for example, comprise an electrical conductor.
[0020] The various pivot planes (of the pivot arm and the pivot lift) can be offset from one another, in particular by a direction of offset outside (i.e., with a directional component perpendicular to) one of the various pivot planes. For example, the various pivot planes can be offset from one another such that they are arranged (essentially) parallel to one another. Alternatively, the various pivot planes can also be inclined relative to one another.
[0021] For the purposes of the present disclosure, “substantially parallel” may encompass an angular range of 170° to 190°, preferably 175° to 185°, particularly preferably an angular range of 179° to 181°.
[0022] The swivel arm and the swivel lever can swivel (move) without rolling (without fulfilling a rolling condition). The swivel arm and the swivel lever can each swivel / move in a single (swivel) plane.
[0023] The pivoting of the outlet element can be effected by means of a relative movement of the pivot arm and the pivot lever to each other, in particular by means of a rotation in a direction from the first outlet element pivot point to the second outlet element pivot point.
[0024] At least one, in particular each, of the outlet element pivot points can have a pivot point recess. At least one, in particular each, of the pivot arm pivot points can have a pivot point recess. At least one, in particular each, of the pivot lever pivot points can have a pivot point recess.
[0025] The swivel angle range between maximum outlet element swivel angles (and / or maximum swivel lever swivel angles and / or maximum (further) swivel arm swivel angles and / or maximum (further) switching element swivel angles) can be at least 180°. In particular, the swivel angle range can be between 180° and 250°, especially between 200° and 250°.
[0026] The outlet element can be pivoted symmetrically around a neutral position (corresponding to 0°). The (two) maximum outlet element pivot angles can thus have a value in the range from -125° to -90° (in particular from -125° to -100°) and from 90° to 125° (in particular from 100° to 125°).
[0027] The switching element can be formed with a first pivot jaw (with the first, second, and third switching element pivot points) and a second pivot jaw spaced therefrom. Furthermore, the second pivot jaw can be pivotally connected to the fixed bearing element at a fourth switching element pivot point. The second pivot jaw can be pivotally connected to the pivot arm at a fifth switching element pivot point and pivotally connected to the pivot lever at a sixth switching element pivot point, which is spaced from the fifth switching element pivot point. In particular, this allows the first pivot jaw and the second pivot jaw to pivot at the same (pivoting jaw) pivot angle (when pivoting the switching element). In other words, the first and second pivot jaws can pivot synchronously.
[0028] A switching element pivot angle swept during pivoting of the switching element (and / or the pivot jaw pivot angle swept during pivoting of the first and second pivot jaws) can be equal to an outlet element pivot angle swept during pivoting of the outlet element. For example, if the switching element is pivoted by 90°, the outlet element can also be pivoted by 90°. In particular, a pivot angle range between maximum switching element pivot angles can be equal to the pivot angle range between the maximum outlet element pivot angles.
[0029] For each pivot jaw pivot angle, a direction (a direction vector) from the second switching element pivot point to the third switching element pivot point can correspond (be equal to) a direction (a direction vector) from the fifth switching element pivot point to the sixth switching element pivot point. For each pivot jaw pivot angle, a direction from the first switching element pivot point to the second (and / or third) switching element pivot point can correspond to a direction from the fourth switching element pivot point to the fifth (or sixth) switching element pivot point.
[0030] For each pivot jaw pivot angle (and / or each outlet element pivot angle), a direction from the second mediating element pivot point to the third mediating element pivot point may correspond to a direction from the first outlet element pivot point to the second outlet element pivot point.
[0031] The winding device can further comprise a further fixed bearing element and / or a further switching element. Preferably, the further switching element can be pivotally connected to the further fixed bearing element at a first further switching element pivot point. Furthermore, the further switching element can be pivotally connected to the pivot lever at a third further switching element pivot point and / or can be rotationally connected to the switching element at the third switching element pivot point.
[0032] The winding device can further comprise a further pivot arm. Preferably, the further connecting element can be pivotally connected to the further pivot arm (and / or the pivot arm) at a second further connecting element pivot point and / or can be rotationally fixedly connected to the connecting element at the second connecting element pivot point.
[0033] Furthermore, the further switching element can be formed with a first further pivoting jaw with the first, second and third further switching element pivot points and a second further pivoting jaw spaced therefrom. The second further pivoting jaw can be pivotally connected to the further fixed bearing element at a fourth further switching element pivot point. Furthermore, the second further pivoting jaw can be pivotally connected to the pivot arm and / or the further pivot arm at a fifth further switching element pivot point. The second further pivoting jaw can be pivotally connected to the pivot lever at a sixth switching element pivot point, which is spaced (offset) from the fifth switching element pivot point. In this way, when the further switching element is pivoted, the first further pivoting jaw and the second further pivoting jaw can be pivoted at the same pivot angle.
[0034] The switching element and the further switching element can be pivotable (by means of the rotationally fixed connection(s)) with the same pivot angle. In particular, the first pivot jaw and the first further pivot jaw can be mounted coaxially for pivoting (at the first switching element pivot point and at the first further switching element pivot point). Analogously, the second pivot jaw and the second further pivot jaw can be mounted coaxially for pivoting (at the fourth switching element pivot point and at the fourth further switching element pivot point). In other words, the (mathematical) axes of rotation of the first pivot jaw and the first further pivot jaw (and / or the second pivot jaw and the second further pivot jaw) can coincide.
[0035] The pivot lever can be arranged between the pivot arm and the additional pivot arm. Furthermore, the pivot lever and / or the pivot arm and / or the additional pivot arm can be arranged between the switching element and the additional switching element.
[0036] In addition, at least one of the elements pivot lever, pivot arm, further pivot arm, mediating element and further mediating element can be arranged between the fixed bearing element and the further fixed bearing element.
[0037] The pivot lever, the pivot arm, the further pivot arm, the switching element, and the further switching element can be pivotably arranged and / or pivotably mounted in different (preferably mutually parallel) planes. In particular, the pivot lever, the pivot arm, and the switching element can be pivotably arranged and / or pivotably mounted in different (preferably mutually parallel) planes.

The first pivot jaw and / or the first further pivot jaw can be arranged at a (respective) center piece of the pivot lever and / or the pivot arm and / or the further pivot arm.
[0039] The winding device can be designed to be mirror-symmetrical with respect to a pivoting plane of the pivot lever as the axis of symmetry. For example, the switching element and the further switching element can be arranged mirror-symmetrically with respect to the pivoting plane of the pivot lever. The pivot arm and the further pivot arm can also be arranged mirror-symmetrically with respect to the pivoting plane of the pivot lever.
[0040] The swivel arm, the swivel lever, and the switching element can each be swiveled in different (preferably parallel) swivel planes. The swivel arm, the additional swivel arm, the swivel lever, the switching element, and the additional switching element can each be swiveled in different (preferably parallel) swivel planes.
[0041] In particular, the pivot lever can be pivoted in a pivot lever pivot plane. The (further) pivot arm can be pivoted in a (further) pivot arm pivot plane.

The second and the third switching element pivot point can have a distance (offset) along the (for example (essentially) parallel to) the switching element pivot plane. The fifth and the sixth switching element pivot point can have a distance along the (for example (essentially) parallel to) the switching element pivot plane.

[0048] The third axis can be arranged so that it can be guided along a second pivot lever guide on the pivot lever. The fourth axis can be arranged so that it can be guided along a second pivot arm guide on the pivot arm and / or along a second further pivot arm guide on the further pivot arm.
[0049] The first axis and the second axis can be arranged (substantially) parallel to each other. The third axis and the fourth axis can be arranged (substantially) parallel to each other. In particular, the first axis, the second axis, the third axis, and the fourth axis can each be arranged (substantially) parallel to each other.
[0050] At least one of the first, second, third, and fourth axes can be arranged perpendicular to the pivoting plane of the pivot lever. At least one of the first, second, third, and fourth axes can be arranged perpendicular to the pivoting plane of the (further) pivot arm.

[0060] The winding device can further comprise a servomotor or pneumatic drive unit configured to pivot the switching element (and / or the further switching element). In particular, the drive unit can be configured to drive at least one of the first pivoting jaw, second pivoting jaw, first further pivoting jaw, and second further pivoting jaw. The drive unit can also be configured to (directly) drive the pivot lever and / or the pivot arm and / or the further pivot arm. The pivoting (of the pivot arm and / or pivot lever and / or switching element and / or outlet element) can be directly coupled to a (servomotor) axis movement, in particular across the entire pivot angle range.
[0061] When the pivot arm and the pivot lever are pivoted relative to the fixed bearing element (in any direction, in particular in the horizontal and vertical directions), the center point of the outlet opening can be moved by a maximum of 1 cm, preferably by a maximum of 0.5 cm, particularly preferably by a maximum of 0.1 cm, or by a maximum of 0.05 cm. In other words, when the pivot arm and the pivot lever are pivoted relative to the fixed bearing element, the center point of the outlet opening can be moved within a spatial environment (for example, an ellipsoidal, spherical, cuboidal, or cubic environment) with a diameter (and / or a maximum (side) dimension) of a maximum of 1 cm, preferably a maximum of 0.5 cm, particularly preferably a maximum of 0.1 cm or a maximum of 0.05 cm.
[0062] At least one of the elements (switching element, further switching element, swivel arm, further swivel arm, and swivel lever) can be configured to be infinitely and / or continuously pivotable. Thus, any angle between the maximum pivot angles can be set during pivoting. The component can be a rotor or a stator (or have a rotor or a stator). The winding of the component can comprise the following:
[0063] - Laying the wire on a first side of the rotor or stator by means of an outlet element of the winding device in a first working position,
[0064] - Swiveling the outlet element into a second working position, which has an outlet element swivel angle of at least 180° compared to the first working position, and

[0066] The component can have at least one coil. The component can have an internally slotted stator, in particular with distributed winding. Furthermore, the first side can be a top side (or a bottom side) of the rotor or stator. The second side can be a bottom side (or a top side) of the rotor or stator. The wire can be laid at a peripheral (in particular radially outer) first laying position on the first side and / or at a peripheral (in particular radially outer) second laying position on the second side. Connection (of sections) of the wire can be provided on the first side and / or the second side.
[0067] The first working position can comprise an outlet element pivot angle in a range of 90° to 125° (in particular from 90° to 100°) (relative to a neutral position of the outlet element, in particular with respect to an orientation of the outlet element in the longitudinal direction (essentially) parallel to the pivot lever longitudinal direction). The second working position can comprise an outlet element pivot angle in a range of -125° to -90° (in particular from -100° to -90°) (relative to a neutral position of the outlet element, in particular with respect to an orientation of the outlet element in the longitudinal direction (essentially) parallel to the pivot lever longitudinal direction).
[0068] By pivoting the outlet element with a large pivoting angle range, for example of at least 180°, internal interconnection wires can be laid simultaneously, particularly on the top and bottom sides of the stator.
[0069] The winding of the component may also comprise:
[0070] - Swiveling the outlet element into a winding working position and
[0071] - Creating windings by means of the wire, in particular within a central recess of the rotor or stator and passing the outlet element in the winding working position through the central recess.
[0072] Alternatively, windings can also be created using the wire on an outer side of the component (e.g. an externally slotted stator).
[0073] The winding working position can comprise an outlet element pivot angle in a range of -25° to 25° (in particular from -5° to 5°, especially 0°) (with respect to a neutral position of the outlet element, in particular with respect to an alignment of the outlet element in the longitudinal direction (substantially) parallel to the pivot lever longitudinal direction).
[0074] The windings can be created, for example, after the wire has been laid on the first side and / or before the wire has been laid on the second side.
[0075] The outlet element can have a winding needle (winding nozzle) and / or a winding needle receptacle (winding nozzle receptacle). The outlet opening can be formed at a longitudinal end of the winding needle. The winding needle can be cylindrical, in particular with a circular, oval, or polygonal cylinder base.
[0076] In the neutral position, the winding needle can be aligned horizontally. The winding working position can encompass the neutral position. In the first and / or second working position, the winding needle can be aligned vertically.
[0077] With regard to the winding machine, the winding devices can each be mechanically coupled to one another at a connecting element of one of the winding devices and a further connecting element of an adjacent one of the winding devices, in particular via a respective coupling element. Specifically, a first (and / or second) pivoting jaw of one of the winding devices can be coupled and / or connected to a first (and / or second) further pivoting jaw of an adjacent one of the winding devices. The winding devices can be pivotable together. In particular, respective outlet openings of the winding devices can be pivotable together.
[0078] The winding device can have (or be arranged on) a translation device configured to move the fixed bearing element (together with the further fixed bearing element, the switching element, the further switching element, the pivoting arm, the further pivoting arm, the pivoting lever, and the outlet element). Thus, a starting position of the outlet opening (independent of pivoting) can also be moved in a controlled manner.
[0079] The pivot lever and / or the (further) pivot arm can be tapered in the longitudinal direction towards the outlet element.
[0080] In connection with the method, the configurations described above in connection with the winding device can be provided accordingly (and vice versa). In the context of the present disclosure, interval specifications ("between", "from ... to") are to be understood as encompassing the interval ends.

[0096] Fig. 1 shows a schematic representation of a (same) winding device for various outlet element pivot angles of an outlet element 10 with a winding needle 11 and a winding needle receptacle 11a. The outlet element 10, in particular the winding needle 11, has an outlet opening 12. The gear of the winding device is arranged in a housing 13.
[0097] For each pivot angle, an outlet opening 12 (i.e., its center point) remains essentially stationary. The spatial position of the outlet opening 12 is therefore independent of the outlet element pivot angle. In other words, the spatial position of the outlet opening 12 can be kept (essentially) constant (stationary) during pivoting. This is illustrated by line 14: For each outlet element pivot angle, the outlet opening 12 is located on line 14. Beyond the pivoting, the spatial position (of the center point) of the outlet opening can be additionally shifted, for example by means of a translation device (not shown). The spatial position (specifically the horizontal and vertical position) of the center point of the outlet opening 12 is therefore (essentially) unchanged.
[0098] Figs. 2a to 2e show schematic representations of the outlet element 10 with various outlet element pivot angles and a component 21 to be wound with wire 20, for example a stator or a rotor. In the following, an alignment of the outlet element 10 in the longitudinal direction parallel to the pivot lever longitudinal direction is defined as 0°. Figures 2a to 2e thus show working positions of the outlet element 10 of 100°, 90°, 0°, -90° and -100°, respectively. First, the wire 20 is laid and connected on a first side of the rotor or stator by means of a winding needle 21 of the outlet element 10 in a first working position (outlet element pivot angle 100° (Fig. 2a) or 90° (Fig. 2b)).
[0099] Subsequently, the outlet element 10, including the winding needle 21, is pivoted into a winding working position (outlet element pivot angle 0°), and windings are created in a central recess 22 of the rotor or stator. The outlet element 10 is guided through the central recess 22 (Fig. 2c). The outlet element 10 is then pivoted into a second working position (outlet element pivot angle -90° (Fig. 2d) or -100° (Fig. 2e)), and the wire 20 is laid and connected on a second side of the rotor or stator, opposite the first side.
[0100] Fig. 3 shows an exploded view of elements of the winding device.
[0101] A first pivot jaw 310 and a second pivot jaw 311, which together form a switching element 31, are pivotally connected to a fixed bearing element 30 at a first and a fourth switching element pivot point 34a, 35a, respectively. The first pivot jaw 310 can be pivoted about a pivot axis through the first switching element pivot point 34a, and the second pivot jaw 311 can be pivoted about a pivot axis through the fourth switching element pivot point 35a.
[0102] Similarly, a first further pivoting jaw 310a and a second further pivoting jaw 311a, which together form a further switching element 31a relative to the switching element 31, are pivotally connected to a further fixed bearing element 30a at a first and a fourth further switching element pivot point 36a, 37a, respectively. The first further pivoting jaw 310a can be pivoted about a pivot axis through the first further switching element pivot point 36a, and the second pivoting jaw 311a can be pivoted about a pivot axis through the fourth further switching element pivot point 37a.
[0103] The switching element 31 is further pivotally connected to a pivot arm 32 at a second switching element pivot point 34b and pivotally connected to a pivot lever 33 at a third switching element pivot point 34c, which is spaced from the second switching element pivot point 34b along a switching element pivot plane, so that when the switching element 31 is pivoted, the pivot arm 32 and the pivot lever 33 are pivoted and each retains its spatial orientation.
[0104] The second pivot jaw 311 is pivotally connected to the pivot arm 32 at a fifth switching element pivot point 35b and pivotally connected to the pivot lever 33 at a sixth switching element pivot point 35c, which is spaced from the fifth switching element pivot point 35b. The first pivot jaw 310 and the second pivot jaw 311 can thus be pivoted at the same pivot angle. Mirror-symmetrically to this, the further switching element 31a is pivotally connected to a further pivot arm 32a at a second further switching element pivot point 36b and pivotally connected to a pivot lever 33 at a third further switching element pivot point 36c, which is spaced from the second further switching element pivot point 36b.The second further pivoting jaw 311a is pivotally connected to the further pivot arm 32a at a fifth further switching element pivot point 37b and pivotally connected to the pivot lever 33 at a sixth further switching element pivot point 37c, which is spaced apart from the fifth further switching element pivot point 37b. The first further pivoting jaw 310a and the second further pivoting jaw 311a can thus be pivoted at the same pivot angle.
[0105] The further switching element 31a (in particular the first further pivoting jaw 310a) is connected in a rotationally fixed manner to the switching element 31 (in particular the first pivoting jaw 310) at the second switching element pivot point 34b at the second further switching element pivot point 36b. The further switching element 31a (in particular the first further pivoting jaw 310a) is connected in a rotationally fixed manner to the switching element 31 (in particular the first pivoting jaw 310) at the third switching element pivot point 34c at the third further switching element pivot point 36c. Furthermore, the further switching element 31a (in particular the second further pivoting jaw 311a) is connected in a rotationally fixed manner to the switching element 31 (in particular the second pivoting jaw 311) at the fifth further switching element pivot point 37b at the fifth switching element pivot point 35b.Finally, the further switching element 31a (in particular the second further pivoting jaw 311a) is connected at the sixth further switching element articulation point 37c in a rotationally fixed manner to the switching element 31 (in particular the second pivoting jaw 311) at the sixth switching element articulation point 35c.
[0106] The first pivot jaw 310 and the pivot arm 32 are connected by a first axis (not shown) through the second linkage element pivot point 34b and through a first pivot arm pivot point 40a (see Fig. 4). Furthermore, the first pivot jaw 310 and the pivot lever 33 are connected by a second axis (not shown) through the third linkage element pivot point 34c and through a first pivot lever pivot point 41b (see Fig. 4). The second pivot jaw 311 and the pivot arm 32 are connected by a third axis (not shown) through the fifth linkage element pivot point 35b and through a second pivot arm pivot point 40c (see Fig. 4). Finally, the second pivot jaw 311 and the pivot lever 33 are connected by means of a fourth axis (not shown) through the sixth switching element pivot point 35c and through a second pivot lever pivot point 41d (see Fig. 4).
[0107] The first axis extends along a first axial line 39a, the second axis along a second axial line 39b, the third axis along a third axial line 39c and the fourth axis along a fourth axial line 39d.
[0108] Analogously, the first additional pivot jaw 310a and the additional pivot arm 32a are connected by means of the first axis through the second additional linkage element pivot point 36b and by a first additional pivot arm pivot point 42a (see Fig. 4). Furthermore, the first additional pivot jaw 310a and the pivot lever 33 are connected by means of the second axis through the third additional linkage element pivot point 36c and by the first pivot lever pivot point 41b. The second additional pivot jaw 311a and the additional pivot arm 32a are connected by means of the third axis through the fifth additional linkage element pivot point 37b and by a second additional pivot arm pivot point 42c (see Fig. 4). Finally, the second further pivot jaw 311a and the pivot lever 33 are connected by means of the fourth axis through the sixth further switching element pivot point 37c and through the second pivot lever pivot point 41d.
[0109] The outlet element 10 is pivotally connected to the pivot arm 32 at a first outlet element pivot point 38a and pivotally connected to the pivot lever 33 at a second outlet element pivot point 38b, which is spaced from the first outlet element pivot point 38a, so that when the pivot arm 32 (and possibly the further pivot arm 32a) and the pivot lever 33 pivot, the center of the outlet opening 12 is essentially stationary with respect to the fixed bearing element 30. A relative movement of the pivot arm 32 (and the further pivot arm 32a) and the pivot lever 33 to each other thus causes the pivoting of the outlet element 10.
[0110] The outlet element 10 is arranged at a first longitudinal end of the pivot lever 33 and the pivot arm 32 (and, if applicable, the further pivot arm 32a). The second pivot jaw 311 (and, if applicable, the second further pivot jaw 311a) are arranged at a second longitudinal end (opposite the first longitudinal end) of the pivot lever 33 and the pivot arm 32 (and, if applicable, the further pivot arm 32a).
[0111] Fig. 4 shows schematic representations of elements of the winding device in side view.
[0112] The first axis runs through the second switching element pivot point 34b, the first pivot arm pivot point 40a, a first pivot lever link 41a, the first further pivot arm pivot point 42a, and the second further switching element pivot point 36b. The second axis runs through the third switching element pivot point 34c, a first pivot arm link 40b, the first pivot lever pivot point 41b, a first further pivot arm link 42b, and the third further switching element pivot point 36c.
[0113] The third axis passes through the fifth switching element pivot point 35b, the second pivot arm pivot point 40c, a second pivot lever link 41c, the second pivot arm pivot point 42c, and the fifth pivot element pivot point 37b. The fourth axis passes through the sixth switching element pivot point 35c, a second pivot arm link 40d, the second pivot lever pivot point 41d, a second pivot arm link 42d, and the sixth pivot element pivot point 37c.
[0114] The first pivot arm guide 40b is formed as an arcuate recess in the pivot arm 32 around the first pivot arm articulation point 40a as the arc center point with a swept angle of 250°. The width of the first pivot arm guide 40b is matched to the diameter of the second axis, so that the second axis can be guided along the first pivot arm guide 40b. The arc of the first pivot arm guide 40b is open opposite an arc of the first pivot lever guide 41a in a plan view of the pivot plane.
[0115] Unlike the first pivot arm guide 40b, the second pivot arm guide 40d in the presently illustrated embodiment is formed as an arcuate contour extending along a side surface of the pivot arm 32. Arc ends 43a, 43b are formed by correspondingly shaping the side surface of the pivot arm 32.
[0116] The other scenes 41a, 41c, 42b and 42d are formed accordingly.
[0117] Fig. 5 shows a schematic representation of elements of the winding device for various outlet element pivot angles (100°, 90°, 0°, -90°, -100°) to illustrate the kinematics of the individual components. The wire 20 is fed via wire feed 50, deflected and / or tightened by deflection element 51 (for example, on the pivot arm 32 or the pivot lever 33), and presented at the outlet opening 12 for winding. Drive is provided, for example, by a drive unit 52.
[0118] As illustrated by line 53, for each pivot angle of the outlet element 10 (or the winding needle 11 with the outlet opening 12) from 100° to -100°, the outlet opening 12 remains stationary.
[0119] The arched pivot lever guides 41a, 41c span an angle of 200°.
[0120] Fig. 6 shows a schematic representation of elements of the winding device for various outlet element pivot angles (125°, 90°, 45°, 0°, -45°, -90°, -125°) in another embodiment. Contours of elements partially obscured in the view are shown in dashed lines. The curved pivot lever guides 41a, 41c span an angle of 250°.
[0121] The pivoting jaws 310, 311 of the switching element 31 rotate about the stationary first and fourth switching element pivot points 34a, 35a on the fixed bearing element 30 (see line 60).
[0122] When the pivot arm 32 and the pivot lever 33 pivot / move, the first pivot arm pivot point 40a and the first pivot lever pivot point 41b orbit each other (as well as the first relay element pivot point 34a). Similarly, when the pivot arm 32 and the pivot lever 33 pivot / move, the second pivot arm pivot point 40c and the second pivot lever pivot point 41d orbit each other (as well as the fourth relay element pivot point 35a). Furthermore, when the pivot arm 32 and the pivot lever 33 pivot / move, the first outlet element pivot point 38a and the second outlet element pivot point 38b orbit each other (as well as the outlet opening 12). For each pivoting angle of the outlet element 10 from 125° to -125°, the outlet opening 12 remains stationary with respect to the fixed bearing element 30.
[0123] Fig. 7 shows a schematic representation of a multiple arrangement of individual winding devices 70, for example as part of a winding machine. The individual winding devices 70 are mechanically coupled to one another, for example, each at one of the connecting elements 31 and the further connecting elements 31a, in particular via coupling elements 71. For example, a first (and / or second) pivoting jaw of one of the individual winding devices 70 can be coupled and / or connected to a first (and / or second) further pivoting jaw of an adjacent one of the individual winding devices. The individual winding devices 70 are jointly driven and pivoted by means of a central drive 72.
[0124] Fig. 8a shows a schematic representation of a winding machine in a front view with a plurality of individual winding devices 70, by means of which components 21 are wound, in a common housing 80. Fig. 8b shows a schematic representation of the winding machine in a side view in section.
