The winding device further comprises a fifth electric motor for rotating the winding body receptacles and the winding body arranged thereon. This winding device allows the winding of even more complex formed bobbins, which in particular have portions with divergent winding axes and / or winding directions. For example, to be wound pins, also referred to as connection pins, deviating from a main winding axis, d. H. from an axis of rotation of the formed as an electric coil to be wound bobbin. Therefore, for the winding of the pins and the material guide bar to align accordingly. This can be done with high precision by means of the electric motors.

In this way, by means of the winding device to wind a variety of winding goods, for example, coils, in particular electric coils, with a coil wire or parts of electric motors with a corresponding wire or other coils or spindles with wires or threads or other bobbins with another wrapping material. In particular, in this way a plurality of differently shaped bobbins of electrical coils are to be wound, which may have pins which are aligned in a plurality of directions. With winding devices, which pneumatic drives This is not possible since they each have only two end stops in each direction of movement, so that the material guide bar can only be moved in each direction of movement to one of these end stops. Intermediate positions are not possible. The electric motors, in contrast, allow movement to any intermediate position on a path of travel between the respective end stops.

In a particularly preferred embodiment, the winding device is designed for the production of coils formed as coils, in particular as electrical coils. In this embodiment, the rotatable winding body receptacles are formed as bobbin receptacles, on each of which a bobbin designed to be wound winding body is to be arranged. The material guide bar is then designed as a wire guide bar. Its material guide units are designed as wire guide units, which each lead a coil wire as a winding material.

Conveniently, the material guide bar is rotatably mounted on a U-shaped bracket, wherein the axis of rotation extends through legs of the bracket and wherein the fourth electric motor between the legs of the bracket is arranged on the axis of rotation. This is a particularly advantageous embodiment of the winding device, as in this way a length and thus a required space of the material guide bar against solutions which have pneumatic drives side of the material guide bar, is considerably reduced. In addition, a greater stability of the material guide beam and lower vibrations are achieved.

Preferably, the electric motors are each designed as servomotors. This allows a highly accurate control and / or regulation of the electric motors and in this way an exact movement and positioning of the material guide beam.

The winding device advantageously comprises a control and / or regulating unit, by means of which the electric motors can be controlled and / or regulated in such a way that the material guide bar can be moved to arbitrary predeterminable trajectories into any predetermined position. By this control and / or regulating unit, which is expediently designed as a CNC control and / or regulation (computerized numerical control), highly accurate winding operations are possible. By means of an appropriate programming of this control and / or regulating unit in the form of a corresponding CNC software, it is possible in this way to specify positions to which the material guide bar is to move in each case, and to specify for each such position a respective trajectory on which the Position should be achieved. The respective position of the material guide bar is formed by its position in space and by its rotational position on the axis of rotation. Of course, the respective positions and trajectories are all within a possible range of motion, which is limited by respective mechanical conditions of the winding machine, d. H. by respective maximum achievable displacement or rotational positions in the individual directions of movement.

Preferably, the electric motors are controllable and / or controllable by means of the control and / or regulating unit such that material outlets of the material guiding units each remain at a currently predetermined spatial point of the three-dimensional coordinate system during rotation of the material guide bar. Since these material outputs are not located on the axis of rotation about which the material guide bar is rotatable, a highly complex control and / or regulation of at least some of the four electric motors is required for such an operation. In this way, a change of a winding direction is made possible, wherein a tension of the winding materials to be wound is maintained, but also not too large, to prevent cracking of the respective winding material to be wound. This makes it possible, for example, to wind coils of more complex design, and in particular of pins of these coils, which have an orientation deviating from the main winding axis of the winding body and, for example, also from a perpendicular to this main winding axis. The pins are then aligned, for example, in an angle deviating from 0 ° and 90 ° to the main winding axis. In such a particularly preferred winding device for the production of winding products designed as electrical coils, the material outlets are correspondingly designed as wire outlets.

Furthermore, the fifth electric motor can also be controlled and / or regulated with this control and / or regulating unit. This fifth electric motor is advantageously also designed as a servo motor. As a result of the highly precise control and / or regulation also possible for this fifth electric motor, the winding body receptacles and the wound bodies arranged on them are also highly precisely rotatable, so that the winding bodies can be positioned in a predetermined angle of rotation. This allows the highly accurate alignment of a respective predetermined region of the winding body, for example, from their pins. Due to the common control and / or regulation of the five electric motors are on to align each of these areas to be wound areas of the winding body and the material outputs of the material guide units highly accurate to each other and to move relative to each other, thereby also allow the winding complex complexed winding body.

In a method according to the invention for operating such a winding device, which comprises a plurality of rotatable winding body receptacles, on each of which a winding body to be wound, and a material guide bar comprises, arranged on each for each winding body receiving a material guide unit for supplying a winding material to the respective winding body to be wound is, the material guide bar is shifted by means of a first electric motor in the x-direction, by means of a second electric motor in the y-direction, by means of a third electric motor in the z-direction of a three-dimensional coordinate system and rotated by a fourth electric motor about an axis of rotation which is parallel to x Direction is aligned. The winding body receptacles and the winding body arranged thereon are rotated by means of a fifth electric motor. By means of this method of operating the winding device, it is also possible to wind winding packages of complex design, which in particular have partial areas with winding axes and / or winding directions deviating from one another. For example, to be wound pins, also referred to as connection pins, deviating from a main winding axis, d. h, from a rotational axis of the formed as an electric coil to be wound bobbin. Therefore, for the winding of the pins and the material guide bar to align accordingly. This can be done with high precision by means of the electric motors.

In this way, a variety of winding materials can be wound, for example, coils, in particular electric coils, with a coil wire or parts of electric motors with a corresponding wire or other coils or spindles with wires or filaments or other bobbins with another wrapping material. In particular, in this way a plurality of differently shaped bobbins of electrical coils are wound, which may have pins that are aligned in a variety of directions. With winding devices, which have pneumatic drives, this is not possible because they each have only two end stops in each direction of movement, so that the material guide bar in each direction of movement is only to move to one of these end stops. Intermediate positions are not possible. The electric motors, in contrast, allow movement to any intermediate position on a path of travel between the respective end stops.

In a particularly preferred embodiment, such electrical coils are produced by means of a winding device designed to produce coils, in particular electrical coils. In this embodiment, the rotatable winding body receptacles are formed as bobbin receptacles, on each of which a bobbin designed to be wound winding body is arranged. The material guide bar is then designed as a wire guide bar. Its material guide units are designed as wire guide units, which each lead a coil wire as a winding material.

The electric motors of the winding device are expediently controlled and / or regulated by means of a control and / or regulating unit in such a way that the material guide bar can be moved to arbitrarily predeterminable trajectories into any predetermined position. By this control and / or regulating unit, which is expediently designed as a CNC control and / or regulation (computerized numerical control), highly accurate winding operations are made possible. By means of an appropriate programming of this control and / or regulating unit in the form of a corresponding CNC software, it is possible in this way to specify positions to which the material guide bar is to move in each case and to specify for each such position a respective trajectory on which the Position should be achieved. The respective position of the material guide bar is formed by its position in space and by its rotational position on the axis of rotation. Of course, the respective positions and trajectories are all within a possible range of motion, which is limited by respective mechanical conditions of the winding machine, d. H. by respective maximum achievable displacement or rotational positions in the individual directions of movement

The electric motors are preferably controlled and / or regulated by means of the control and / or regulating unit such that material outlets of the material guiding units each remain at a currently predetermined spatial point of the three-dimensional coordinate system during rotation of the material guide bar. Since these material outputs are not located on the axis of rotation about which the material guide bar is rotatable, a highly complex control and / or regulation of at least some of the four electric motors is required for such an operation. In this way, a change of a winding direction is made possible, wherein a tension of the to be wound Winding materials is maintained, but not too large, to prevent cracking of the respective winding material to be wound. This makes it possible, for example, to wind coils of more complex design, and in particular of pins of these coils, which have an orientation deviating from the main winding axis of the winding body and, for example, also from a perpendicular to this main winding axis. For example, the pins are aligned at an angle deviating from 0 ° and 90 ° to the main winding axis. In such a particularly preferred winding device for the production of winding products designed as electrical coils, the material outlets are correspondingly designed as wire outlets.

Advantageously, the electric motors are controlled and / or regulated such that the material guide bar performs helical movements. This allows a winding solely by the movements of the material guide beam, so that, for example, a winding of areas is possible, which are aligned differently from a direction of rotation and / or main winding axis and / or winding direction of the respective winding body.

Furthermore, the fifth electric motor can also be controlled and / or regulated with this control and / or regulating unit. This fifth electric motor is advantageously also designed as a servo motor. By thus enabling highly accurate control and / or regulation of this fifth electric motor and the winding body shots and arranged on these winding body can be rotated with high accuracy, so that the winding body can be positioned in a respective predetermined angle of rotation. This allows the highly accurate alignment of a respective predetermined region of the winding body, for example, from their pins. Due to the common control and / or regulation of the five electric motors in each case to be wound areas of the winding body and the material outputs of the material guide units can be highly accurately aligned and moved relative to each other, thereby also allow the winding complex winding bobbin.

Preferably, connecting pins of the winding bodies formed as coils of coils, in particular of electric coils, are wound when the winding body is at rest by moving the material guiding beam with a respective wrapping material designed as a coil wire. This is made possible by the helical movements of the material guide beam. These pins are often different from the main winding axis, d. H. arranged and / or aligned by the axis of rotation of the winding body, so that a winding by rotating the winding body is not possible. Therefore, the winding body is not moved to its winding, but these pins are after the material guide beam is aligned appropriately, wound by moving the material guide beam. By appropriate helical movements, the wrapping material, d. H. the coil wire wrapped around these pins.

The 1A to 4B show cross-sectional views and respective associated front views of a winding device 1 for the production of winding goods 2 with a material guide bar positioned in various exemplary positions 3 , Here is the winding device 1 in the cross-sectional views each with a housing 4 and in the front views for the sake of clarity, each without the housing 4 shown. This case 4 serves in particular a conclusion of a working space in which by means of a method for operating the winding device 1 bobbin 5 with a wrapping material 6 be wound to this way the winding goods 2 manufacture. In particular, for reasons of safety at work, this working space is through the housing 4 locked. The housing 4 is only open, for example, by means of the winding device 1 finished winding goods 2 to remove and / or rewinding wound body 5 in the winding device 1 to arrange.

The 5 to 11 show different representations of the material guide bar 3 , which on a U-shaped bracket 7 is arranged, which serves as a holder of the material guide beam 3 serves. The 12 to 14 show various embodiments of windings 2 , which by means of the winding device 1 and the method for their operation can be produced. The winding goods shown here 2 are designed as coils, in particular as electrical coils. The illustrated and described below preferred embodiment of the winding device 1 is a winding device 1 for the preparation of these formed as electrical coils winding goods 2 , In this winding device 1 is therefore the material guide bar 3 designed as a wire guide bar. The winding body 5 formed as coils winding goods 2 are formed as bobbin, each with a winding material designed as a coil wire 6 to be wound.

The winding device 1 comprises a plurality of designed as a bobbin shots rotatable winding body receptacles 8th , on each of which a winding body to be wound 5 is to be arranged. The material guide bar 3 the winding device 1 points for each bobbin holder 8th each formed as a wire guide unit material guide unit 9 for feeding the wrapping material 6 to the respective winding body to be wound 5 on. Each of these material guide units 9 is a cutting unit 10 assigned, by means of which the respective formed as a coil wire winding material 6 after completely winding the respective winding material 2 to sever, so that the winding material 2 , In the example shown here, the coil, from the winding device 1 can be seen. In this case, the removal of the finished winding goods takes place 2 from the respective winding body receptacle 8th and arranging a new, to be wound bobbin 5 on the respective winding body receptacle 8th by means of a transport unit 11 the winding device 1 ,

The material guide bar 3 is by means of a first electric motor M1 in the x-direction x, by means of a second electric motor M2 in y-direction y, by means of a third electric motor M3 in the z-direction z of a three-dimensional coordinate system displaceable and rotatable by means of a fourth electric motor M4 about a rotation axis D, which is aligned parallel to the x-direction x. The electric motors M1, M2, M3, M4 are each designed as servomotors. Furthermore, the winding device still has a fifth electric motor, not shown here, for rotating the winding body receptacles 8th and the winding body arranged thereon 5 on.

The material guide bar 3 is like in the 5 to 11 shown in more detail on the U-shaped bracket 7 rotatably arranged. In this case, the axis of rotation D passes through legs of the bracket 7 , Of the fourth electric motor M4 is between the legs of the bracket 7 arranged on the axis of rotation D. This is a particularly advantageous embodiment of the winding device 1 , as in this way a length and thus a required space of the material guide beam 3 compared to solutions known from the prior art, which pneumatic drives side of the material guide beam 3 have significantly reduced. In addition, this provides greater stability of the material guide bar 3 and achieved lower vibration.

The winding device 1 includes a control and / or regulating unit, not shown here, by means of which the electric motors M1, M2, M3, M4 are controllable and / or controllable such that the material guide bar 3 can be moved to any predetermined position curves in any predetermined position. Examples of such positions, in which the material guide bar 3 is movable in the 1A to 4B shown.

This is the material guide bar 3 in 1A in a lower position in the field of winding body recordings 8th positioned and rotated so that the material guide units 9 are vertically aligned. In 1B is the material guide bar 3 in a lower and by the winding body shots 8th positioned spaced position, wherein the material guide units 9 are also vertically aligned. 1C shows a front view of these lower positions of the material guide bar 3 ,

The 2A and 2 B show the material guide bar 3 in the lower and from the winding body shots 8th spaced position, where now the material guide bar 3 is twisted about the rotation axis D that the material guide units 9 are aligned horizontally. In the 3A and 3B is the material guide bar 3 in an upper and by the winding body shots 8th positioned spaced position, wherein the material guide units 9 are vertically aligned. In the 4A and 4B is the material guide bar 3 in an upper and by the winding body shots 8th positioned spaced position, wherein the material guide units 9 are aligned horizontally.

By this control and / or regulating unit, which is expediently designed as a CNC control and / or regulation (computerized numerical control), highly accurate winding operations are possible. By means of an appropriate programming of this control and / or regulating unit in the form of a corresponding CNC software, it is possible in this way to specify positions to which the material guide bar 3 should move each, and to specify for each such position a respective trajectory on which the position is to be achieved. The respective position of the material guide bar 3 is formed by its position in space and by its rotational position on the axis of rotation D. The respective positions and trajectories are of course all within a possible range of motion, which by respective mechanical conditions of the winding machine 1 is limited, ie by respective maximum achievable displacement or rotational positions in the individual directions of movement. The in the 1A to 4B shown positions are therefore only examples of possible positions, the material guide bar 3 can assume, in particular possible extreme positions are shown.

In particular, the electric motors M1, M2, M3, M4 can be controlled and / or regulated by means of the control and / or regulating unit such that material outlets designed as wire outlets 12 the material guide units 9 while turning the material guide beam 3 each remain at a currently predetermined spatial point of the three-dimensional coordinate system about the rotation axis D. Because these material exits 12 not on the axis of rotation D, but by turning the material guide beam 3 pivoting on a circular path around this axis of rotation D, it is necessary during the rotational movement of the material guide beam 3 to carry out simultaneously compensating movements in the y-direction y and in the z-direction z of the three-dimensional coordinate system and during which the alignment of the material guide beam 3 in x-direction x of the three-dimensional coordinate system to maintain the material exits 12 the material guide units 9 while turning the material guide bar 3 to keep the rotation axis D respectively at the currently predetermined spatial point of the three-dimensional coordinate system. Therefore, even for such an operation highly complex control and / or regulation of at least some of the four electric motors M1, M2, M3, M4 is required.

In this way, a change of a winding direction is made possible, wherein a tension of the winding materials to be wound 6 is maintained, but also not too large, a tearing of the respective winding material to be wound 6 to prevent. This allows, for example, as in the 12 to 14 shown, a winding even more complex trained coils and in particular of pins 13 these coils, which one of a main winding axis W of the winding body 5 have a different orientation.

Furthermore, the electric motors M1, M2, 3, M4 can be controlled and / or regulated by means of the control and / or regulating unit such that the material guide bar 3 helical Performs movements. This allows in particular, the pins 13 formed as a bobbin winding body 5 at standstill the bobbin 5 solely by moving the material guide bar 3 with a respective winding material designed as a coil wire 6 to wrap. For these helical movements it is necessary to use the material guide bar 3 to move in the x-direction x, y-direction y and z-direction z of the three-dimensional coordinate system.

Furthermore, the fifth electric motor can also be controlled and / or regulated with this control and / or regulating unit. This fifth electric motor is advantageously also designed as a servo motor. By thus enabling highly accurate control and / or regulation of this fifth electric motor and the winding body shots 8th and the winding body arranged thereon 5 be rotated with high precision, so that the winding body 5 can be positioned in a respective predetermined angle of rotation. This allows the highly accurate alignment of a respective predetermined region of the winding body 5 , For example, from their pins 13 , Due to the common control and / or regulation of the five electric motors can each be wound areas of the winding body in this way 5 and the material outlets 12 the material guide units 9 highly accurately aligned with each other and moved relative to each other, thereby also the winding complex-formed winding body 5 to enable.

This winding device 1 allows the winding of even more complex formed bobbins 5 which in particular have partial regions with different winding axes and / or winding directions. For example, different from the one in 12 shown bobbin 5 with parallel to the main winding axis W aligned pins 13 , the pins to be wound 13 deviating from the main winding axis W of the winding body to be wound 5 aligned, as in the 13 and 14 shown. The main winding axis W corresponds to a rotation axis of the winding body 5 during rotations on the respective winding body receptacle 8th the winding device 1 , Main windings of the formed as an electrical coil winding material 2 be by turning the bobbin 5 by means of the winding body receptacle 8th educated. It is on the bobbin 5 wound wrapping material 6 , ie the coil wire, during the rotation of the bobbin 5 once or several times by means of the respective material guide unit 9 from one end face to the other end face of the winding body 5 emotional. Are the connection pins 13 , as in 12 represented, parallel to the main winding axis W, ie parallel to the axis of rotation of the winding body 5 aligned, so in a similar way, the pins 13 with the winding material designed as a coil wire 6 be wound.

However, this is the case in the 13 and 14 exemplified, formed as a bobbin electrical coil bobbins 5 not possible. The in 13 illustrated winding body 5 has connecting pins 13 on, perpendicular to the main winding axis W of the bobbin 5 are aligned and the in 14 illustrated winding body 5 has connecting pins 13 on, each in a deviating from 0 ° and 90 ° angle to the main winding axis W of the bobbin 5 are aligned. Therefore, to wind the pins 13 also the material guide bar 3 align accordingly. This can be done with high precision by means of the electric motors M1, M2, M3, M4, in particular due to the control and / or regulation of the electric motors M1, M2, M3, M4 designed as servomotors. The pins 13 , which differ from the main winding axis W of the bobbin 5 are aligned, then at standstill of the bobbin 5 solely by corresponding helical movements of the material guide beam 3 wound.

In this way, by means of the winding device 1 and the method for their operation in particular a variety of differently shaped bobbin electrical coils to wind, which pins 13 which are aligned in a plurality of directions. With winding devices according to the prior art, which have pneumatic drives, this is not possible because they have in each direction of movement in each case only two end stops, so that the material guide bar 3 in each direction of movement only one of these end stops to move. Intermediate positions are not possible. The electric motors M1, M2, M3, M4 in contrast allow the movement to any intermediate positions on a movement path between the respective end stops.
