    The invention relates to a method for producing a fiber composite or hybrid component, comprising the steps of processing an insert in a preparation station, transporting the insert with a transport device from the preparation station in a cavity of a clamping unit of an injection molding machine, encapsulating the insert with an injection unit from an injection molding in the cavity injected plastic melt to the fiber composite or hybrid component and removing the fiber composite or hybrid component including insert from the clamping unit by a transport device. In addition, the invention relates to an arrangement for producing a fiber composite or hybrid component with a preparation station, in which an insert is machinable, a closing unit of an injection molding machine, with a cavity in which the machined insert is arranged or arranged, an injection unit of the injection molding machine for injection of plastic melt in the cavity while encapsulating the insert disposed in the cavity and a transport device through which the insert is transportable in the preparation station and in the cavity of the clamping unit.
    In recent years, the production of multi-component injection molded parts has greatly increased. In particular, demand is increasing for fiber-reinforced injection molding components. In this case, so-called fiber composite components or hybrid components are usually produced from prefabricated or preconsolidated parts in which a fiber structure already exists. These can also be referred to as organo sheets or prepregs. The production of fiber composite or hybrid components requires the introduction of reinforcing or functionalizing elements (so-called inserts or inserts).
    The handling concepts known from the prior art are technically and time-consuming, above all for the introduction of these inserts. An example of the production of such composite or hybrid constructions is disclosed in DE 10 2010 019 625 A1. Another method for producing a reinforced composite product is shown in WO 2009/019102 A1. A further disadvantage of these methods is the relatively large expenditure on production. ...... and highlighted the large space requirement for the required handling robots. In addition, by attacking the inserts with the handling robots, undesired deformation or even destruction of the fabric structure or fiber structure can take place.
    The object of the present invention is therefore to provide a comparison with the prior art improved method or an improved arrangement. In particular, a simplified production of a fiber composite or hybrid component is to be achieved, in which the inserts are moved as accurately as possible and uninfluenced.
    This is achieved for a method having the features of the preamble of claim 1 and for an arrangement having the features of the preamble of claim 5, characterized in that the insert during machining in the preparation station, during transport to the closing unit and during the molding in the cavity remains in connection with the same transport device. Thus, no encompassing by different handling robots must be done, but the insert always remains attached to the transport device or rests on this. The transport device thus forms a conveyor system for the transport of submitted, partially or fully applied, consolidated or unkonsoiidierten 2D and / or 3D textile structures (inserts).
    Moreover, the present invention makes possible a continuous handling concept-without handing over or extensive process paths-and the cycle time for producing the fiber-composite or hybrid components is considerably shortened. In other words, the transport device passes through both the preparation station and the closing unit and thus forms the basis for a production line for producing a fiber composite or hybrid component. Based on the idea of the production line, the transport device with its transported material (insert) passes through all the process steps of manufacturing the fiber composite or hybrid component, which consist of at least two components, of which at least one component from outside into the 9 · 9 9 9 9 9 9 · 9 · 9 9 9 9 9 9 9 9 * 99 Μ 99 999 999 999 3 actual process unit must be introduced. This component is transported by the transport device.
    Preferably, it can be provided that the transport device has a conveyor belt, via which the insert is transported. The insert can be unattached or loose on the conveyor belt. Preferably, however, the insert is connected directly to the conveyor belt. But it can also be provided that the insert is fastened on a carrier or gripper on the conveyor belt. The connection between the insert and the transport device can preferably be designed in a form-fitting, cohesive or non-positive manner. For an efficient design of the transport device can be provided that the conveyor belt is formed circumferentially. This circulating component of the conveyor can be either two-piece or one-piece. The inserts may be directly connected to the conveyor or applied to a carrier which is being conveyed or which itself is the conveyor. In the latter case, the carrier, which at the same time forms the transport device, would have to be separated again from the applied additional components (second insert) or from the finished component or left in the component by cutting off the remaining transport device formed by the insert. If the transport device is a deformable film, this can also remain until the molding in the tool or in the component after the drawing and forming of the textile reinforcement structures.
    In addition to the actual process unit {injection molding machine with clamping unit and injection unit), the transport system also passes through a preparation station and preferably also a post-processing station. Depending on the component to be manufactured and the process used, additional work steps are carried out here. The supply can be horizontal or vertical. Likewise, it may be a horizontal or vertical clamping unit. Of course, also intermediate layers (for example 45 ° or 30 °) are conceivable. Basically, the placement of the cavity in the tool outside the
    Close axis of the closing unit of the injection molding machine done. For this purpose, the tool can be extended out of the area of the closing unit.
    Process steps which can be carried out in the preparation station are insertion of the insert, loading of the insert with an additional component, drying of the insert, heating or softening of the insert, impregnation of the insert, binders and / or spraying an adhesive, etc. For the production Of fiber-reinforced hybrid components is particularly preferably provided that the preparation station has a heating device through which, preferably preconsolidated, insert softenable. In this variant, the present invention has the particular advantage that by the retention of the insert on the transport device, the flexible and unstable expectant insert still held securely and as desired on the transport device and thus passes in the desired form of the preparation station in the clamping unit.
    In order to achieve a multifunctional replaceable arrangement or as complete as possible a method for producing a fiber composite or hybrid component, preferably a post-processing station for processing the fiber composite or hybrid component after encapsulation of the insert with plastic melt, wherein the insert also in the post-processing station in conjunction with the transport device remains provided. The post-processing steps that can be performed here are trimming, cooling, drying and / or deburring, etc.
    As insert can serve a 2D or 3D textile structure, which is placed over the entire surface or partially on the transport device. For example, such textile structures may be monofilament yarn, multifilament yarn, coated yarn, twisted yarn, spun yarn, friction spun yarn, central reinforcing fiber (eg, glass fiber), fabric, biaxial scrim, multiaxial scrim, 3D braid, circular braid, triaxial round scrim, spacer scrim. or Konturengewirke, nonwoven or the like may be formed. The fibers used to make the textile structures may include glass fibers, carbon fibers, basalt fibers, "* *" · * · t · · · · · · · · »5
    Aramid fibers, polymer fibers or hybrid yarns (glass and thermoplastic fibers). However, inserts can also be consolidated semi-finished products (organic sheets, tapes, prepregs, etc.) of fiber composites. Resins (RTM - Resin Transfer Molding) or low-viscosity reactive polymer substances (RIM - Reaction Injection Molding, in situ polymerization of PA) are used for the infiltration and impregnation of unconsolidated textile structures. For encapsulation and spraying of functional elements on consolidated semi-finished products injection units are used for the injection of thermoplastic melts. As introduced or injected plastic components (may also be referred to as starting components) in the context of the invention thus resins, reactive polymer substances and thermoplastic melts or plastic melts can be understood.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Show:
    1 shows schematically an arrangement with closing unit, injection unit, preparation station and transport device,
    2 shows an arrangement with a transport device including conveyor belt,
    Fig. 3 shows an arrangement with a transport member formed by the insert itself and
    Fig. 4 directly connected to the conveyor belt inserts.
    1 shows the essential components for carrying out a method for producing a fiber composite or hybrid component 9. In this case, the transport device 7 on the one hand through the preparation station 1 and on the other hand by the clamping unit 2. This transport device 7 has two conveyor belts 8, by drive devices 10th are driven. Between the two conveyor belts 8, an insert 4 is clamped or fastened before or when the preparation station 1 is reached. This preconsolidated and a fabric or a fiber structure (eg with endless glass fiber) having insert 4 passes • »······················· by moving the Conveyor belt 8 in the preparation station 1. In this preparation station 1, a heater is provided which heats the Einlegeteii 4 and thereby softened. This can additionally be done by pressure. Subsequently, the remaining on the transport device 7 Einlegeteii 4 enters the clamping unit 2, in whose tool a cavity 5 is formed. By injecting plastic melt via the injection unit 6 into the cavity 5, the fiber composite or hybrid component 9 is formed. When injecting a thermoplastic, this is formed by cooling or when injecting a thermoset fiber composite or hybrid component 9 is completed by reacting. After further processing of the still remaining on the transport device 7 insert 4 or fiber composite or hybrid component 9 this passes to the end of the production line, where it can be removed or further processed or stored accordingly.
    Fig. 2 shows schematically an arrangement with a preparation station 1, a closing unit 2 and a post-processing station 3. In this embodiment, the transport device 7 consists of two two-sided conveyor belts 8, between which a carrier 11 is clamped. On this support 11, a Einlegeteii 4 is applied and heated in the preparation station 1. Thereafter, the heated and resting on the carrier 11 Einlegeteii 4 enters the clamping unit 2, where it is molded. Subsequently, a post-processing, e.g. by cooling in the finishing station 3, after which the produced fiber composite or hybrid components 9 can be stored or stacked.
    In Fig. 3, the insert 4 itself forms the transporting device 7 and is e.g. guided by a role not shown here in the form of a web through the preparation station 1, closing unit 2 and finishing station 3. In the area of the preparation station 1, an additional component 12 (eg metallic amplifier) is placed and the web-shaped insert 4 together with additional component 12 passes into the cavity 5 of the vertical clamping unit 2. Finally, in the finishing station 3 the overmolded area is removed from the path of the insert 4 together with the additional component 12 punched out, whereby the hole 13 is formed in the transport device 7. in Fig. 4, the insert 4 is attached directly to the conveyor belts 8 of the transport device 7. The conveyor belts 8 thus form a kind of clamping frame for the inserts 4. The transport device 7 is moved by the drive device 10 and the inserts 4 arrive at the preparation station 1, clamping unit 2 and the finishing station 3 one after the other for their processing.
    The present invention thus provides an improved method and an improved arrangement for producing a fiber composite or hybrid component 9, wherein the technical and time expenditure compared with the prior art is reduced by one component (insert 4 or additional component 12) of the produced Fiber composite or hybrid component 9 is always attached to the transport device 7 during the manufacturing process or rests on this. There is thus no cumbersome, complicated and damage-prone transfers of the insert 4 between the individual stations 1, 2 and / or 3 of the manufacturing process.
