Description

Technical Field

[0001] The present invention relates to a die element support device for a manufacturing assembly for prefabricated elements and / or precast elements and / or prepackaged elements, in particular for wind turbine blades, the die element support device comprising a plurality of upper support portions for carrying longitudinal die elements for manufacturing prefabricated elements and / or precast elements and / or prepackaged elements. Furthermore, the present invention relates to a manufacturing assembly for prefabricated elements and / or precast elements and / or prepackaged elements, in particular for wind turbine blades, the manufacturing assembly comprising the die element support device, and to a manufacturing system. Background Art

[0002] Wind turbines generally include a rotor having a plurality of wind turbine blades. For example, such a wind turbine can convert the mechanical energy of the wind into electrical energy. Due to the search for large-scale energy production, wind turbines and thus wind turbine blades have huge dimensions, making their manufacture a major challenge for wind turbine manufacturers. Although wind turbine blades have long been made of fiber-reinforced materials, which involves handling large parts such as fiber mats by casting the shell of the wind turbine blade, techniques have been proposed to assist in the manufacture of wind turbine blades.

[0003] For example, it has been proposed to use prefabricated elements or preforms accordingly. Such prefabricated elements are preformed smaller parts or segments of a wind turbine blade, which are used to construct the corresponding wind turbine blade shell. The prefabricated elements are premanufactured separately and then arranged and aligned in a blade mold according to the required geometry of the wind turbine blade to be manufactured. The prefabricated elements can be arranged in the blade mold for casting the entire wind turbine blade or large wind turbine blade parts.

[0004] The prefabricated elements can include one or more components, such as one or more textile layers, wherein these components are at least partially attached to each other by using a binder / adhesive. For example, the components of the prefabricated elements can include a plurality of fiber mats and / or core materials, which are locally attached to each other to allow their mutual handling. This facilitates the arrangement of the components in the blade mold. The prefabricated elements can be understood as semi-solid elements. In particular, the textile components of the prefabricated elements, such as fiber mats, can be made of glass fiber, carbon fiber or aramid fiber. These layers remain unaffected by the binder so that they can be filled with resin later during the manufacture of the rotor blade. For example, the core material can include balsa wood, foam, etc. Using prefabricated elements in particular allows reducing the cycle time for producing wind turbine blades.

[0005] As a variant, pre-packaged elements have been proposed. Here, components such as fiber mats and / or core materials are placed in a mold element so as to adopt the shape of the molding surface. This shape is preserved by tightly packing these components in a vacuum bag.

[0006] In another method, the use of pre-cast elements has also been proposed, i.e., parts or sections of a wind turbine blade that already include cured resin and can also be used for constructing a wind turbine blade.

[0007] For example, a preform element can be made in a manufacturing assembly, which can also include a preform mold. Such a manufacturing assembly typically includes a mold element, such as a mold housing, which includes a molding surface shaped according to the desired shape of the preform element, and these components are placed on this molding surface to adopt the corresponding shape. Preferably, the preform element is covered in a vacuum bag to stabilize the stack of components that make up the preform element.

[0008] In modern wind turbines, wind turbine blades with different geometries, especially different sizes, are employed. Thus, if different types / sizes of wind turbine blades are to be manufactured, the size of the preform element varies according to the size of the blade for which they are intended. In particular, the preform element mainly varies in height and width, where, additionally, even within a specific type of wind turbine blade, different shapes may occur.

[0009] However, nowadays, manufacturing assemblies for preform elements, especially preform molds, are mostly designed for specific preform element sizes and / or shapes. In particular, a preform element of a given size and shape is manufactured in a dedicated manufacturing assembly for preform elements. However, this is not a viable method for mass production, as a very large number of manufacturing assemblies, as well as in many cases lifting and / or transportation tools, would be required.

[0010] WO 2019 / 115 522 A1 proposes a method for manufacturing at least two preforms for molding a wind turbine blade, wherein the preform mold structure used has a molding surface with a variable shape such that, by using an actuator, the shape of the molding surface can vary at least between a first and a second configuration. However, a mold element with a molding surface of variable shape has a complex and expensive construction and, in particular, does not allow scaling of the shape provided by such an adaptable mold element. In particular, such a mold structure cannot provide molding surfaces for different widths and / or heights of the preform element to be manufactured.

[0011] Similar problems also occur for the manufacture of pre-packaged elements and pre-cast elements. Summary of the Invention

[0012] An object of the present invention is to provide an improved manufacturing setup which allows for the production of a variety of prefabricated elements and / or precast elements and / or prepackaged elements, in particular of different sizes and / or shapes, which manufacturing setup is flexible, cost-effective and in particular also easily transportable.

[0013] This object is achieved by providing a die element support device according to claim 1, a manufacturing assembly according to claim 14, and a manufacturing system according to claim 15. Advantageous embodiments are described by the dependent claims.

[0014] According to the present invention, there is provided a die element support device for a manufacturing assembly of prefabricated elements and / or precast elements and / or prepackaged elements, in particular for wind turbine blades, the die element support device comprising a plurality of upper support portions for carrying longitudinal die elements for manufacturing prefabricated elements and / or precast elements and / or prepackaged elements. The die element support device further comprises a longitudinal carrier element for the longitudinal die elements, in particular a carrier beam, and a positioning device having a plurality of pivotable, in particular horizontally extending, rotating arms, the rotating arms being attached at one end to the carrier element and having attached thereto respective support portions at the other end.

[0015] Here, the die element, in particular the die housing, is a rigid shape-retaining element having a molded surface shaped according to the desired shape of the prefabricated element and / or precast element and / or prepackaged element, on which surface the components are placed during manufacturing to assume the corresponding shape. By adding die elements, the die element support device, on which the die elements are supported, provides a prefabrication die (and / or precast die and / or prepackaging die) for the manufacturing assembly of prefabricated elements and / or precast elements and / or prepackaged elements.

[0016] Thus, the use of a flexible die element support device is proposed which can be adapted to a plurality of different longitudinal die elements, in particular die elements having different shapes and / or sizes. The die element support device comprises a plurality of rotating arms extending at least substantially horizontally from a main / central carrier element, preferably from a carrier beam. Here, the cross-section of the carrier element, in particular the carrier beam, can be substantially the same over its length. The rotating arms can preferably be attached at the lateral sides of the carrier element. Each rotating arm carries at least one, in particular exactly one, of the plurality of support portions. By being pivotable, the rotating arms, which are part of the positioning device for horizontally positioning the support portions, allow the support portions to be positioned at different distances from the carrier element in a width direction perpendicular to the longitudinal direction in which the carrier element extends. Preferably, the support portions of the rotating arms can support the die elements at their lateral edges, in particular along the lateral flanges of the die elements, in particular the die housing.

[0017] When properly supported on the die element support device in the manufacturing component, the longitudinal directions of the longitudinal die element and the longitudinal carrier element are the same. Thus, the die element support device can be adjusted to support die elements of different widths by being able to position the support part at different positions in the width direction using the rotary arms of the positioning device. Preferably, the rotary arms can swing independently of each other to even allow adjustment to a variable width along the length of the die element.

[0018] In a particularly preferred embodiment, the die element support device further includes height adjustment equipment for each support part, which is particularly arranged between the rotary arm and its support part. The height adjustment equipment allows the height of the support part to be adjusted separately. For example, each height adjustment equipment may include a telescopic device. Here, the end of the rotary arm that bears the support part may include a vertically extending orifice for receiving a height-adjustable rod to which the support part is attached. Generally, the height adjustment equipment may include a controllable, particularly electric and / or hydraulic actuator. The die element support device may include operating elements, which are, for example, positioned at the rotary arm and / or the carrier element and / or provided as at least one remote control device. Preferably, in addition to the actuator for height adjustment, for at least one degree of freedom, the positioning device may also include an actuator that particularly pivots at least one of the rotary arms, resulting in different positions in the width direction. Certain control processes can also be automated, for example, by using a control device to control the actuator.

[0019] Thus, generally speaking, the height adjustment equipment allows for further flexibility of the die element support device because different heights of the support part can be selected. In addition, additional adaptability to the dimensions and / or shape of the die element and thus the prefabricated element and / or precast element and / or prepackaged element to be manufactured is also provided. For example, the flange or other lateral edge regions of the die element can be supported by the support part of the rotary arm. Here, for example, due to special design features, easy adjustment to a varying height along the length of the die element is possible, and such special design features may be provided, for example, for a lightning protection system, etc. For example, if the flange of the die element is locally higher than the rest of the length, the corresponding support part can be adjusted to that greater height. Thus, as already discussed, the positioning device can be used for adjustment to a locally greater or smaller width. However, the provided height adjustment options can also be used to generally adjust the working height, particularly for additional tools or auxiliary devices during manufacturing. For example, the flange height can be adjusted to provide optimal working conditions for the manufacturing personnel.

[0020] According to the present invention, a device is provided to implement a manufacturing assembly for precast elements and / or precast elements and / or prepackaged elements, which is flexible in terms of the dimensions and / or shape of the precast elements and / or precast elements and / or prepackaged elements to be manufactured. In particular, die elements for a large number of dimensions and / or shapes of precast elements and / or precast elements and / or prepackaged elements can be provided to form a manufacturing system according to the present invention. To produce a precast element and / or precast element and / or prepackaged element of another dimension and / or shape, the previous die elements can be removed, the die element support device can be adjusted to support the new die elements, and the new die elements can be supported on the die element support device. The adjustment is facilitated by providing a rotating arm and preferably a height adjustment device. The support part and the rotating arm can be understood as "adjustable legs" that can be adjusted preferably in terms of their height and the position of their support part respectively.

[0021] Therefore, the manufacturing assembly or workstation can correspondingly handle die elements with different geometries. The manufacturing assembly is not specifically for a certain wind turbine blade, especially a certain size / dimension of a wind turbine blade. Therefore, the manufacturing assembly can be used to manufacture precast elements and / or precast elements and / or prepackaged elements for several different wind turbine blade types. To achieve this, a plurality of different die elements can be provided.

[0022] As will be further detailed below, the die element support device can be implemented modularly, such that it can be disassembled and tightly packed into a transport receptacle such as a container, for example. For example, the rotating arm can be positioned at least substantially parallel to a carrier element (such as a folding wing).

[0023] Generally speaking, the manufacturing equipment can also be reused, or even recycled for use with another wind turbine blade type if the blade type is discontinued. Therefore, in addition to cost efficiency, a quick conversion to the manufacture of a new blade type is possible. Since only the die elements are replaced (and the die element support device is adjusted accordingly), the process of manufacturing precast elements and / or precast elements and / or prepackaged elements for wind turbine blades can be assimilated or even standardized for different types of wind turbine blades, making it easier for the manufacturing personnel to switch between the production of different blade types. In particular, the manufacturing assembly can also be used for the manufacture of different types of wind turbine blades. For example, the manufacturing assembly described herein can be used for integral blade manufacturing as well as blade half manufacturing. Finally, the manufacturing assembly can be used for both precast element / prepackaged element and precast element manufacturing.

[0024] In particular, a manufacturing system can be envisaged in which at least one die element support device can be combined with a plurality of die elements of different sizes and / or shapes, all of which can be used together with the die element support device to construct certain different types (in particular sizes) of manufacturing assemblies for preform elements and / or precast elements and / or prepackaged elements. In particular, each such manufacturing assembly may be capable of manufacturing a preform element, such as a concave preform element, which can be packaged in a vacuum bag and / or a vacuum foil. In particular, it may even be possible to package more than one preform element and / or precast element and / or prepackaged element on top of one another during manufacturing. With regard to the vacuum bag, different types and designs can be employed, such as those described in the later published European patent application 21209596.2.

[0025] In an embodiment, the rotary arms can be attached to the carrier element by attachment means, where a pair of two associated rotary arms extending to different sides of the carrier element can be attached by at least one of the attachment means, namely a common attachment means. Thus, the rotary arms can be provided in pairs, with one rotary arm pivotable at each side of the carrier element, such that in particular different lateral distances in the width direction can be adjusted between the corresponding support parts. In particular, the required width can be adjusted by pivotally moving the rotary arms symmetrically, thereby allowing a symmetrical positioning of the support parts relative to the carrier element and thus allowing a firm and stable support of the die elements.

[0026] Additionally or alternatively, the attachment means forming part of the positioning means can be releasable. That is to say, the rotary arm or the pair of rotary arms can be mounted at different positions along the length of the carrier element, thus providing further flexibility. For example, by correspondingly placing or even removing the rotary arms along the length of the carrier element, in particular the carrier beam, the die element support device can be adjusted to accommodate different lengths of die elements.

[0027] Preferably, the positioning means can include a sliding element of the attachment means that can slide on the carrier element, in particular the carrier beam, when the attachment means is at least partially released. Thus, for example, the carrier element, preferably the carrier beam, can be understood as a track on which the rotary arms are guided on the attachment means. In a specific embodiment, the attachment means can include a lateral plate and at least a top plate. In particular, the lateral plates can each include shoulders that rest on the lower surface of the carrier element, and / or the attachment means can also include a bottom plate. The lateral plates can be fastened to the top plate and optionally to the bottom plate by screws and / or bolts. Partially loosening the screws and / or bolts allows the sliding element, which includes the lateral plate and the top plate, optionally also the bottom plate, to slide along the carrier element. For example, in this embodiment, the cross-sectional shape of the carrier element, in particular the carrier beam, along its length can be constant, such as square and / or rectangular. Generally speaking, the rotary arms can also be attached to the lateral plates by hinges.

[0028] Such an attachment device that can slide on the carrier element can of course also be applied to other components of the die element support device, especially the wheels and / or support legs to be discussed below, if at least partially released / relaxed.

[0029] In an embodiment, the positioning device may further include length adjustment means for the rotating arm and / or replaceable rotating arms of different lengths. For example, such length adjustment means may include telescopic means. In the case where the die element has a width that cannot be reached by the rotating arm, the rotating arm can be replaced with a correspondingly longer rotating arm and / or a rotating arm with an adjustable length can be used, such as a telescopic arrangement.

[0030] Preferably, the die element support device may further include at least one column element having a support portion thereon and extending in the vertical direction (height direction), the column element being supported on the carrier element, especially slidable in the longitudinal direction. In this way, the at least one column element can be positioned in the width direction between two lateral support portions carried by the rotating arm, especially a pair of rotating arms as described above, and / or support an intermediate section of the die element in the width direction. Such a column element with additional support portions can be provided to prevent deflection and / or deformation of the die element by providing additional support by positioning the column element in the intermediate section below the die element. In particular, if the die element is symmetrically bent, the column element can support the die element at the lowest point if the support portions of the rotating arms are arranged symmetrically around the support flange or other edge regions of the carrier element and the die element. However, it is also conceivable to specifically select an asymmetric positioning of the support portions on the rotating arm such that the lowest part of the asymmetrically bent die element is positioned above the carrier element and can thus be supported by the at least one column element.

[0031] To support the column element on the carrier element, especially the carrier beam, a simple holder adapted to the shape of the carrier element may be sufficient, the holder especially extending at least partially above the lateral surface of the carrier element. In this way, the at least one column element can be understood to be attached by gravity. However, fixing means can be provided to fix the position of the holder. It can be easily added when needed and positioned along the length of the carrier element.

[0032] In advantageous embodiments, wheels and / or support legs are provided for supporting the carrier element on the floor. In the case of wheels, locking means, in particular brakes, may additionally be associated with the wheels. However, it is also conceivable to have support legs in addition to the wheels and to lower the wheels to a position below the feet of the support legs in order to be able to move the carrier element and thus the entire die element support device. In particular, it is even possible to move the entire manufacturing assembly, i.e. the die element support device on which the die element is placed, which in particular has at least one preform element and / or precast element and / or prepackaged element or at least parts thereof located in the die element. For example, after the parts of the preform element have been packaged in the die element, at least one preform element on the die element (which die element is in turn supported by the die element support device) can be moved to a heating and / or cooling device, in particular an oven. Here, the preform element can be transported into the heating and / or cooling device by means of a corresponding actuating device, and / or the die element on the die element support device can be moved directly into the heating and / or cooling device. In the latter case, after the heat treatment or cold treatment has been completed, the preform element can be moved to the next processing step, for example at a demoulding station and / or unpacking station and / or blade die. If the heating and / or cooling is carried out directly at the preform die including the die element support device and the die element, the preform element or elements located in the die element can also be moved directly to some other further processing step.

[0033] It should be noted that the die element support device can also be moved to a replacement position where, after the previous die element has been removed, a different die element, in particular a die element of a different size, can be assembled to the die element support device. This allows various die elements to be interchanged at a central location with dedicated processing equipment for this operation. Instead of this central procedure, the replacement of the die element can also take place at the individual die stations.

[0034] Regarding the movement of the die element support device, in a preferred embodiment, a towing coupling can be provided which is attached to the carrier element, in particular at at least one longitudinal end of the carrier element. For example, such a towing coupling can include a tail etc. which is hingedly attached to the carrier element and can be coupled to a towing vehicle to pull and / or push the die element support device to another position.

[0035] Preferably, the support part may include a particularly flat contact surface for contacting the die element, and tilting means for tilting the contact surface into different contact orientations, in particular a spherical joint. The die element may have different flange designs, or generally edge designs. Additionally, the support part may be used where the die element generally has a surface that slopes outward from the horizontal plane. In all these cases, preferably, additional degrees of freedom may be provided for the support part by providing tilting means that allow the contact surface to slope outward from the horizontal plane to adjust to the orientation of the die element to which it will be joined. For example, the flange of the die element may include a tilted die surface bounded by an edge shoulder. In such an embodiment, the support part, in particular the contact surface, may be placed adjacent to the edge shoulder in an orientation corresponding to the tilted die surface. Preferably, the tilting means may include a spherical joint to particularly allow tilting / pivoting about a rotational axis extending in the longitudinal direction, independent of the pivot angle of the rotating arm.

[0036] In an embodiment, the support part may also include a low-friction material and / or rollers in the contact area with the die element. In particular, having a low-friction material on the contact surface already mentioned allows for the easy addition and removal of the die element, for example if the die element is to slide onto or off the contact surface in the contact area. Due to the rotating arm, rollers that are preferably adjustable in their rolling direction allow for similar advantages to be achieved.

[0037] The die element support device may also include at least one longitudinal working platform for the manufacturing personnel. Such a working platform will be placed longitudinally along the die element. In this way, a flexible walkway is provided for the manufacturing personnel along the die element / preform die.

[0038] In a preferred embodiment, the die support device may also include height adjustment means for the working platform, in particular telescopic means and / or a scissor mechanism. In this way, the height of the working platform can be adjusted to suit the height of the die element, so that an optimal working position for the manufacturing personnel can be achieved. In particular, the operator can reach the molding surface directly or indirectly. As height adjustment means for the working platform, for example, a scissor mechanism may be provided. Of course, for example, other embodiments such as telescopic means may also be used.

[0039] Generally, the working platforms may be provided on each side of the die element. These working platforms can be adjusted independently in height. The working platforms may also include climbing means, such as pivotally hinged ladders or stairs.

[0040] In an embodiment, the carrier element may comprise different modular sections along a longitudinal direction, wherein these modular sections are releasably attached to one another by coupling means. For example, in the case of a carrier beam, the carrier element may be divided into a number of longitudinal modular sections which have flanges at least at their ends that can be connected to another modular section. By means of these flanges, the modular sections can be bolted or screwed together. For example, the carrier element may be divided into the following modular sections, namely a head module and / or a tail module, and / or an intermediate module. If components can be releasably attached or mounted to the carrier element, they can also form additional modules, such as at least one wheel module, at least one rotating arm module, at least one support leg module and / or a combination of these modules. As a first advantage, this modularity allows the number of the individual modules employed to be adjusted as required, in particular for the length of the die element. In addition, since the individual modules can be replaced when they need repair or are defective, this facilitates repair. The modular die element support device can be easily assembled and disassembled and tightly packed, for example, in a container.

[0041] The manufacturing assembly for prefabricated elements and / or precast elements and / or prepackaged elements according to the invention comprises a die element support device according to the invention and a die element supported on the die element support device, thus providing a complete prefabricated die (or correspondingly a precast die / prepackaged die). All the features and advantages discussed with respect to the die element support device can similarly apply to the manufacturing assembly. In particular, the manufacturing assembly can be part of a manufacturing system which includes different replaceable die elements, in particular die elements of different sizes and / or different shapes.

[0042] Here, the die element, in particular the die housing, can be constructed / manufactured in a design already proposed in the art or in an alternative novel design. For example, the die element may comprise a conventional laminate, which is relatively heavy and expensive but suitable because it allows heat transfer through the layers of the laminate, for example for heating and / or cooling the binder of the prefabricated element. In other embodiments, a sandwich structure of a core may be provided, which, for example, includes glass fiber layers on both sides of a core element, and the core element may be made of a core material such as balsa wood or foam. Such a construction is inexpensive, strong and relatively light in weight. However, it does not provide an ideal heat transfer through the die element. If a carbon fiber layer is combined with a foam-based core material, such a sandwich structure can be made even lighter in weight. However, due to the use of carbon, such a construction can be more expensive.

[0043] In another embodiment, the sandwich structure can be modified to include at least one layer providing internal channels and / or voids. For example, such an additional layer can be placed on the laminate stack such that the laminate stack and the additional layer can be encapsulated between outer layers made of, for example, fiberglass. For example, the additional layer can be a ParaBeam™ layer. These internal channels and / or voids in the die element can be advantageously used to heat and / or cool the preform element and / or the precast element and / or the prepackaged element from below, in particular by supplying a cooling or heating fluid to the internal channels and / or voids.

[0044] These internal channels can also be provided in a 3D printed configuration of the die element. Here, the internal channels can also be used to provide cooling or heating to the preform element and / or the precast element and / or the prepackaged element from below.

[0045] In another embodiment, it is also conceivable to provide a die element consisting of a honeycomb-based core material sandwiched between outer layers including carbon fibers to further reduce the weight of the die element.

[0046] Generally, the manufacturing assembly can additionally include at least one auxiliary device that provides at least one component for the preform element and / or the precast element and / or the prepackaged element to the manufacturing personnel. For example, the at least one auxiliary device can provide fiber mats and / or fiber materials and / or core materials and / or binders. For example, the component (in particular the fiber mat) can be arranged on a pallet suspended from a gantry crane or a suspension crane, and the pallet can be oriented in the width direction or the longitudinal direction. Here, preferably, the height of the pallet suspended from the crane can be adjusted such that the manufacturing personnel can easily access these components, in particular the fiber mats, in particular from both sides of the die and / or on the working platform. It should be noted that if a height-adjustable working platform is provided, these working platforms can be adapted to be in an optimal working position, which depends in particular on the body size of the operator. Regarding the longitudinally oriented suspension crane or gantry crane, it should be noted that these cranes can move between parallel-oriented and positioned manufacturing assemblies to supply components to multiple manufacturing positions. However, the auxiliary device can also be a fiber laying machine, which can be CNC-controlled and includes a cutting device that cuts the fiber material into the required length while laying it directly into the preform die. The fiber material stock can be placed near the manufacturing assembly such that the fiber laying machine can be loaded separately or continuously.

[0047] It should be noted that such an auxiliary device can also be configured to directly apply a binder to the component, such as a fiber mat, as has already been proposed in the art.

[0048] In the present invention, the mold elements can be replaced so that prefabricated elements and / or precast elements and / or prepackaged elements of different geometries, in particular different shapes and / or dimensions, can be manufactured. Here, several ways of replacing the mold elements can be envisaged. For example, the transport and / or storage means for the mold elements, which are part of the manufacturing assembly and / or the manufacturing system, can be moved to the mold element support means, where a lifting means, for example comprising a lifting crane and / or using a vacuum lifter, can be used to move the mold element. For example, using the lifting means, a previously used mold element can be lifted from the support part of the mold element support means and placed in a storage position and / or a transport position on the transport and / or storage means. Then, after the mold element support means has been adjusted, in particular by using a height adjustment device and / or a positioning device, to accommodate the new mold element, another mold element can be lifted using the lifting means and moved onto the mold element support means.

[0049] Here, if the mold elements are transported and / or stored in an upright position, a vacuum lifter comprising a rotatable lifting yoke is particularly preferred. Using a vacuum lifter with a rotatable yoke, a horizontally oriented mold element can be rotated to an upright vertical orientation after being lifted from the mold element support means and can be correspondingly lowered to a storage and / or transport position on the storage and / or transport means or into a warehouse.

[0050] In another method, the mold elements can also be stored or transported in a horizontal position so that, when the transport and / or storage means is positioned at a longitudinal end of the mold element support means, they can, for example, simply slide back and forth on the mold element support means. In another embodiment, the transport and / or storage means can be moved above the mold element so as to grip it from below and lift it from the support part to the transport and / or storage position.

[0051] Preferably, in such an embodiment, the transport and / or storage means can be a rack comprising a frame structure that can be moved on wheels. Support elements are guided in or on the vertical beams of the frame structure, and the height can be adjusted by moving the support elements in or on the vertical beams. In this way, for example, once a mold element is supported on the support elements of the transport and / or storage means, it can, for example, be lifted upwards so as to provide space for receiving another mold element on the support elements placed below a previously used set of support elements. Of course, this space can also be provided by moving the already received mold element downwards and using a higher placed set of storage elements to receive another mold element. If a mold element is to be unloaded, it can be positioned at the correct unloading height in the same way and unloaded from the corresponding set of support elements of the transport and / or storage means.

[0052] Preferably, in any case, the transport and / or storage device may also be adapted to flexibly handle different geometries of the die elements. For example, the support elements of the transport and / or storage device may include rotating arms, as already discussed above. To provide height adjustability of the support elements, the vertical beams may include tracks in which or on which the support elements may be mounted to move up and down, in particular also separately, in particular within a group. Alternatively, releasable and movable grippers may be used. If rotating arms are used, die elements of different widths may be handled; individual height adjustability allows handling of die elements having different heights at different sides.

[0053] It should be noted that these transport and / or storage devices may also be used for transporting and / or storing prefabricated elements and / or precast elements and / or prepackaged elements manufactured using the manufacturing assembly. Description of the Drawings

Detailed Description

[0055] Figure 1 Manufacturing assembly 1 of a first embodiment including a die element support device 2 is schematically shown. The die element support device 2 includes a carrier element 3, which is a carrier beam in this case, and a rotary arm 7, which is part of a positioning device 6, is pivotally attached at one end to the carrier beam using an attachment device 4 including a hinge 5. At the other end, a support portion 10 for supporting a die element 9 having corresponding flanges 11 is mounted via a height adjustment device 8, which is a telescopic device in this case. For reasons of better illustration, the die element 9 is shown in a displaced position along the longitudinal direction 12 to provide a better view of the die element support device 2. In the first embodiment shown, the carrier element 3 also includes support legs 13 for supporting the die element support device 2 on the floor. For example, the carrier element 3 may be releasably mounted to the floor.

[0056] To manufacture a preform element using the manufacturing assembly 1, which is a preform element for a wind turbine blade in the embodiment shown here, components of the preform element, such as including fiber mats, core materials, and / or binders, are placed in the die element 9, which has a molding surface 14 defining the desired shape for the preform element. By placing the components on the molding surface 14, they assume the desired shape. A binder is supplied to locally attach the components together so that they can be handled as a single object, i.e., the preform element. As will be further discussed later, the binder can be activated by heat and hardened / cured by cooling, which may also already occur in the manufacturing assembly 1. Alternatively, an oven or other heating and / or cooling device may be used. In many embodiments, the preform element will be packaged in a vacuum bag and / or vacuum foil for improved handling. Thus, the workstation provided by the manufacturing assembly 1 may also be referred to as a packaging station.

[0057] Although the manufacturing assembly 1 for a preform element for a wind turbine blade is described in these embodiments, embodiments of the present invention may also relate to other preform elements and / or precast elements and / or prepackaged elements.

[0058] As can be seen in Figure 1 , the die element 9 has a certain width, or generally a certain size and / or shape. In a manufacturing system, different die elements 9 having different sizes and / or shapes may be provided for interchangeable use on the die element support device 2. To be adjustable to accommodate these different die elements 9, several degrees of freedom may be provided, as further shown with respect to Figure 2 Further shown.

[0059] As already explained, the swivel arm 7 is pivotally attached to the carrier element 3 via the hinge 5, as also shown by the arrow 15. Thus, by pivoting the swivel arm 7 to different positions, such as the dashed position 16 as shown, different distances 17, 18 in the width direction (perpendicular to the longitudinal direction 12) can be selected. Additionally, in this embodiment, the height adjustment device 8 includes a rod 20 that is slidably received in an aperture at the end of the swivel arm 7, and the height of the support element can also be adjusted in the height direction 21. Figure 2 The support part 10 can be individually adjusted in the height direction 21 by the height adjustment device 8, for example, to account for variations in height of the flange or the other side edge of the die element 9, such as for special features required in the preform element. For example, these features can be related to a lightning protection system and provide locally varying widths and / or heights.

[0060] As

[0061] As Figure 3 schematically shown, the die element support device 2 can be adapted to support an even wider die element 9 by replacing the swivel arm 7 with a longer swivel arm 7'.

[0062] Figure 4 Partially illustrated is a second embodiment of the die element support device 2, which also has a carrier element 3 in the form of a load-bearing beam and pivotally attached swivel arms that have a support part 10 at their other ends, which support part 10 is also height-adjustable by the height adjustment device 8, as in all the illustrated embodiments. Also as provided in all the embodiments shown here, the swivel arms 7 are attached in pairs along the length of the carrier element 3 at opposite lateral sides of the carrier element 3.

[0063] In this case, the carrier element 3 also has wheels 22 attached to it, and these wheels 22 can be lowered so that the support legs 13 no longer contact the floor, as shown by the double arrow 23. In this way, the entire die element support device 2 can be easily moved. These wheels 22 can also be provided in other embodiments where they are not shown.

[0064] Furthermore, a height-adjustable column element 24 that extends vertically and also has a support part at its upper end is shown as being placed on the carrier element 3 via a retainer 25 to further support the die element 9 in the intermediate section, as will be discussed below.

[0065] In Figure 4 the die element support device 2 is shown in a compact, space-saving transport state with the swivel arms 7 folded up.

[0066] Figure 5Another embodiment is shown in a partial view, where again the complete manufacturing assembly 1 with the die element 9 is shown, which is supported on the support part 10 by means of its flange 11. Here, it can be seen that the column element 24 can be positioned at the lowest point of the die element 9 for further support, especially if the die element 9 is symmetric. As explained, it can be adjusted in the height direction 21. Since it is simply positioned on the carrier element 3 using the retainer 25, it can also be moved, for example, in the longitudinal direction, for example, to be positioned between the support parts 10 of a pair of rotary arms 7.

[0067] In addition to Figure 4 this, at at least one longitudinal end of the carrier element 3, a towing coupling 26 is additionally provided, which can be hingedly attached to the carrier element 3. For example, a towing vehicle can be coupled via the towing coupling 26 to easily move the die element support device 2 when the wheels extend under the support legs 13. Of course, additional wheels 22 are provided along the length of the carrier element 3. It should be noted that in embodiments with wheels 22 and especially also with the towing coupling 26, even the entire manufacturing assembly 1, especially one with preform elements thereon, can be easily moved, for example, to a heating and / or cooling device, especially an oven, or another station where a processing step is performed, such as an unpacking station and / or a blade die.

[0068] Of course, it should be noted that the retainer 25 can also include fixing means, such as those shown, for example, in Figure 6 as shown.

[0069] Before proceeding to the Figure 6 embodiment, it should be noted that in the previous embodiments of the die element support device 2, not only at least the rotary arms 7, but also other components such as the support legs 13 or the wheel units with wheels 22 can be releasably attached to the carrier element 3 using the attachment means 4. This is further illustrated in Figure 6 where each attachment means 4, 27 includes a transverse plate 28 and a top plate 28' and a bottom plate 28''. If the shown screws are loosened, the attachment means 4, 27 and thus the attached components, especially the rotary arms 7, can be easily moved in the longitudinal direction 12 as indicated by the arrow. The plates 28, 28', 28'' form sliding elements. Thus, further flexibility is provided. For transporting or tightly packing the die element support device 2 into, for example, a container, they can even be completely separated.

[0070] In this regard, Figure 6 another feature regarding the carrier element 3 is also illustrated, which can also be implemented in all embodiments. Here, the carrier element 3 is divided into a plurality of modular sections 29, which can be releasably attached together using flange connectors 87. As shown inFigure 6 It can also be seen that the carrier element 3 can be made simply and lightly of a hollow profile, in particular with a rectangular cross-section.

[0071] In Figure 7 the exploded view, the design of the support part 10 is shown in more detail, which is applicable to all embodiments. As can be seen, the support part 10 includes a contact area 30, which is in this case a flat contact surface 31 for contacting the die element 9. The tilting device 32 consists of a spherical joint 33, such that the contact surface 31 can be tilted from its horizontal position to a plurality of tilted orientations, as indicated by the arrow 34. The spherical joint 33 or generally the tilting device 32 also allows rotation of the contact area 30 / contact surface 31, as indicated by the arrow 35, in particular for compensating for the angled offset caused by the pivoting rotary arm.

[0072] This allows adjustability of the contact surface 31 and thus the entire support part 10 for different designs of the flange of the die element 9, as Figures 8 to 10 further illustrated in Figure 9 and Figure 10 where different configurations of the flanges 11, 11' and 11'' are shown that require the contact surface 31 to be tilted by the tilting device 32. In particular, in

[0073] the contact surface 31 / contact area 30 may include a low-friction material, in particular for allowing the die element 9 to slide on the contact surface 31. In another embodiment, as Figure 11 shown in

[0074] Regarding Figures 7 to 11 the features discussed apply to all embodiments of the die element support device 2 according to the invention.

[0075] Figure 12 Another embodiment of the die element support device 2 for manufacturing the component 1 during use is illustrated. This fourth embodiment can be based on any previous embodiment and additionally includes a working platform 38 extending longitudinally along both sides of the die element 9. The two working platforms 38 are provided on top of a frame 39, which includes height adjustment means 40 for the working platforms 38, which are in this case scissor mechanisms 41. Thus, the working platforms 38 are also height-adjustable, as indicated by the double arrow 42. A climbing device 43, in particular a staircase or ladder, is pivotally mounted to the working platform 38, which may also include a safety fence 44.

[0076] The frame 39 is movable and can be positioned close to the die element 9 as required. The mobility of the working platform 38 in the width direction 19 is indicated by the arrow 45.

[0077] In this way, the die element support device 2 not only allows adjustment to accommodate different die elements 9, but also allows finding the optimal working position with respect to the width direction 19 and the height direction 21.

[0078] In Figure 12 , an exemplary map shows the manufacturing steps for a prefabricated element. Another part of the vacuum foil 46 or the vacuum bag has been placed in the die element 9. The part 47 of the prefabricated element, in this case the fiber mat 48, is currently added by the manufacturer 49.

[0079] Figure 13 Another example of the die element support device 2 is shown, in particular the fifth embodiment, which can also be based on any previous embodiment. Figure 13 The working platform 38 extending along the two longitudinal directions of the die element 9 is shown again. Here, the manufacturing assembly 1 additionally includes an auxiliary device 50 for providing the part 47, in this case the fiber mat 48. The auxiliary device 50 includes a suspension crane 51 having a pallet 52 on which the fiber mat 48 is arranged. The auxiliary device 50 can be moved according to the arrow 53 so that the manufacturer 49 can easily access the fiber mat 48 on the pallet 52. If the height of the pallet 52 is not adjustable or can only be adjusted in a limited way, the height of the support platform 10 and the working platform 38 can be adjusted to achieve the best working conditions. Therefore, the flexibility of the die element support device 2 also applies to the auxiliary device 50.

[0080] Although Figure 13 the suspension crane 51 in Figure 14 is a transverse crane in the width direction 19,

[0081] In Figure 15 an additional embodiment of the manufacturing assembly using a suspension crane 54 is shown, which is longitudinally oriented and can be moved, for example, in the width direction 19 for use at the parallel extending manufacturing assembly 1 / die element 9.

[0082] In Figure 16In the example, the working platform 38 is not used, but the working platform 38 may be provided in other embodiments. In this case, the fiber placement machine 56 is used as the auxiliary device 50. The fiber placement machine 56 includes a cutter that cuts the fiber mat 48 in the current length while laying it directly into the mold element 9, particularly onto the mold surface 14 that has been provided with the vacuum foil 46. The fiber material stock 57 can be placed near the mold element 9 so that the fiber placement machine 56 can be loaded separately or continuously.

[0083] Figure 17 Another example is illustrated, in which a CNC-controlled fiber placement machine 58 is used so that the fiber material / fiber mat 48 is correctly positioned on the molding surface 14.

[0084] In particular, in embodiments using the fiber placement machines 56, 58, and also in other embodiments and in the case of having other auxiliary devices 50, the binder can be directly applied to the fiber mat 48.

[0085] The mold element 9 can generally be made of or constituted by a layer structure accordingly. Here, Figure 18 A first embodiment of the layer structure 59 of the mold element 9 is shown. Here, a conventional laminate 60 is used, which is relatively heavy and expensive, but allows heat transfer through the layers of the laminate 60, so that heating or cooling of the mold element 9 is possible. In Figure 19 In the second embodiment of the layer structure 59 shown in, a sandwich structure is used, in which the core material 61 (in this case balsa wood) is sandwiched between the outer layers 62 made of glass fiber. This is cheap, strong, and relatively light in terms of weight variation, but provides less heat transfer through the layer structure 59.

[0086] In Figure 20 In the third embodiment of the layer structure 59 of, a particularly lightweight sandwich structure is used, in which the core material 63 is foam and the outer layer 62 is also based on carbon fiber.

[0087] In Figure 21 In the particularly advantageous fourth embodiment of, two core materials are sandwiched between the outer layers 62 in the layer structure 59, namely the first core layer 64 that can be a laminate stack, and the second additional layer 65 made of a material (such as ParaBeam™) including internal channels and / or voids. These voids and / or internal channels can be used as cooling and / or heating channels through which cooling and / or heating fluids can be supplied to heat and / or cool the preform element from below.

[0088] Figure 22The fifth embodiment of the layer structure 59 for the die element 9 is illustrated, where, in the sandwich structure, between the outer layers 62 made of carbon fiber, a core material 66 with a honeycomb structure is used to further reduce the weight.

[0089] In Figure 23 the sixth embodiment, a 3D printed forming shell is used as the layer structure 59, which preferably also includes cooling and / or heating channels 67 for supplying cooling and / or heating fluid.

[0090] Figure 24 The first way of storing and / or transporting and moving the die elements 9, 9', 9'' is illustrated, for example when the die elements 9, 9', 9'' are to be replaced at the die element support device 2. For this purpose, a transport and / or storage device 68 can be used, where Figure 24 a first embodiment of such a transport and / or storage device 68 is shown. The transport and / or storage device 68 includes a frame 69, vertical beams 70 are positioned on the frame 69, and height-adjustable holders 71 are mounted thereon to hold the vertically positioned die elements 9, 9', 9'' in an upright position, i.e., vertically oriented. To move the die elements 9, 9', 9'' to and from the die element support device 2, a lifting device 72 can be employed, which in Figure 24 is a crane 73 with a gripper 88.

[0091] Regarding Figure 25 and Figure 26 a particularly preferred embodiment is shown. Here, a vacuum lifter 74 with a rotatable yoke 75 is used as the lifting device 72, where the yoke 75 is rotatable such that in order to place the vacuum-lifted die element 9 on the support part 10 of the die element support device 2, the die element 9 can be rotated from the Figure 25 vertically position shown in Figure 26 to the horizontal orientation shown in

[0092] The die elements 9, 9', 9'' can also be transported and / or stored in a substantially horizontal orientation, as shown for example in Figures 27 to 33 . Here, a different embodiment of the transport and / or storage device 68 is used, which will be described in detail later. Using a suspension crane 76 with a gripper 77, the die element 9' can be pulled out from the transport and / or storage device 68 above the already adjusted die element support device 2 and then lowered onto the support part 10. In particular, the die elements 9, 9', 9'' can also be slid onto the die element support device 2, especially if the contact surface 31 has a low-friction material and / or includes rollers 37.

[0093] Alternatively, as in Figure 28As shown, if the horizontal beam 78 of the transport and / or storage device 68 is removed, the transport and / or storage device 68 can even move above the die element support device 2, such that the lowest die element 9 can simply be lowered onto the support part 10 of the column element 3.

[0094] Generally speaking, as Figure 28 shown in the partial view of, the transport and / or storage device in the second embodiment may also include a frame structure 79, which includes vertical beams 80. In the embodiment shown here, three sets of support elements 81 are mounted to the vertical beams 80, wherein, for each beam 80, the first set of support elements 81 is in the corresponding lowest position, the second set of support elements 81 is in the intermediate position, and the third set of support elements 81 is in the uppermost position. All the support elements include rotary arms 82 for adjusting to different widths of the die elements 9, 9', 9''. In addition, all the support elements 81 are height-adjustable. Now, as Figure 30 shown, if the die element has been placed on a set of uppermost support elements 81, the third set of support elements 81 can be moved upward to bring the die element 9 into the corresponding transport and / or storage position. Here, the die element 9 is also supported on its flange 11.

[0095] As Figure 31 shown, the support elements 81 can be adjusted in height separately to provide a height difference 83, as shown for the die element 9''' supported by the second set of support elements 81 in Figure 31 . Similar to what has been discussed regarding the rotary arm 22, similarly, the rotary arms 82 allow adjustment to different widths 84, 85, as shown for the first and second sets of support elements 81 in Figure 31 . Therefore, the transport and / or storage device 68 of the present embodiment can be easily adjusted to different shapes and / or sizes of the die elements 9, 9', 9'', 9''', which is similar to the die element support device 2.

[0096] Similar or even identical transport and / or storage devices 68 can also be used for transporting and / or storing the manufactured prefabricated elements. For example, as Figure 32 shown, a transport and / or storage device 68 as described in EP 22174530.0 can be used. Here, it is also shown that the lifting device for the die elements 9, 9', 9'', 9''' can also be used to lift the manufactured or at least packaged prefabricated element 86 from the molding surface 14 to the transport and / or storage device 68.

[0097] As Figure 33 shown, most preferably, as already described regarding Figures 27 to 29The described transport and / or storage device 68 can also be used for prefabricated elements 86, for example by sliding the prefabricated element 86 from the die element 9 and its molding surface 14 onto a support element 81 that has been adjusted to the shape and dimensions of the prefabricated element 86.

[0098] Although the invention has been described in detail with reference to preferred embodiments, the invention is not limited to the disclosed examples, and other variations can be obtained by those skilled in the art from the disclosed examples without departing from the scope of the invention.
