Definitions
- Apparatus for the production of fiber preforms which in particular constitute a precursor in the production of fiber-reinforced plastic components
- the invention relates to an apparatus for the production of fiber preforms, which in particular constitute a precursor in the production of fiber-reinforced plastic components, the apparatus having a plurality of unwinding stations for the provision of a plurality of yarns or rovings or ribbons and a plurality of grippers, each one or more yarns or rovings or bands at its beginning, each gripper being reciprocally movable on a path between a maximum position and a pick-up position, and wherein the pick-up position is provided at a yarn transfer point and closer to the unwind station than the maximum position the grippers are each movable individually on substantially parallel paths, so that the yarns or rovings or bands can be clamped in parallel.
- Fiber-reinforced plastic consists of matrix material and of fibers which are embedded in the matrix material and which i.a. provide the tensile strength. Fiber-reinforced plastic is used especially for high in astetete components that should still be as light as possible. Since the fibers impart no strength in the transverse direction, the fibers must be aligned so that their longitudinal direction coincides as well as possible with the respective loading direction. To achieve this, the fibers often have to be laid in different directions. The better and more accurately the fiber layer is adapted to the load and the more uniformly the fibers are arranged, the better the component will be. For components made of fiber-reinforced plastic, there are numerous manufacturing processes. For the production of large numbers of well-applicable methods, however, there are currently only with rotationally symmetrical or plate- or strand-shaped components by winding or plate or extrusion.
- Fiber preforms are first produced corresponding to the desired three-dimensional component shape, so-called preforms, which predominantly consist of fibers which are often arranged one above the other in several layers in order to achieve the necessary fiber directions. Subsequently, the fiber preforms are then soaked or coated with the matrix material, pressed and cured or pressed and consolidated. Both for the production of the fiber preforms and for the impregnation and / or hardening or consolidation of the components molding tools can be used according to the desired component shape, or placed and pressed into the fiber preform or the component.
- the fiber preforms In order for the fiber preforms to have sufficient dimensional stability for further processing, they are provided with small amounts of adhesive or binder and fixed after three-dimensional draping, e.g. by drying or by heating and cooling.
- the fiber preforms are usually created by superimposing and fixing of prefabricated and pre-bonded flat semi-finished products. Such semi-finished products are for example tapes or fabrics, scrims or nonwovens in which a multiplicity of individual yarns or rovings are already woven, sewn or glued into a flat structure.
- a yarn is referred to when using so-called continuous fibers, i. when the fibers are unwound from a spool or from a ball. Many yarns untwisted simultaneously from a spool or from a ball are called yarn bundles or rovings.
- the rovings can consist of up to several ten thousand single yarns, which are also called filaments.
- the band segments can store parallel to each other.
- the laying heads have to deposit the band segments one after the other on a moving carrier material which is each moved by the bandwidth.
- several laying heads have been proposed that lay "gap-free" exactly one bandwidth apart and thus create a closed position together, but for a uniform and exact laying without overlaps or gaps, a very high control effort and a precise tuning are required the different movement speeds needed.
- the object of the invention is to provide a device that can produce heavy-duty and load-oriented fiber preforms with a lower material cost and shorter production time.
- the object is achieved by a device according to claim 1, wherein the adjacent gripper, in particular each adjacent gripper, offset from one another in height. Due to the height offset, the grippers can be arranged in a horizontal direction side by side, that the spanned yarns or rovings or ribbons in the plan view result in a closed surface with uniform fiber density without hindering the gripper thereby. Because of the gripper a greater width than the clamped band, a secure clamping and a uniform thread tension when clamping for all yarns or rovings is guaranteed. With the device according to the invention, a complete layer of yarns or rovings or ribbons can be produced in one working step, which enables higher cycle rates in the production of fiber preforms and thus a considerable advantage.
- the mechanical alignment of the grippers and the yarn transfer points replaces this. It makes sense to have the yarn transfer points offset in the same amount as the grippers.
- the yarn transfer points may preferably comprise clamping devices for holding the beginnings of the yarns or rovings or ribbons.
- the stretched yarns or rovings or ribbons can be placed on a table or by means of a forming tool, which are arranged under the stretched yarns or rovings or ribbons. On the table or on the mold thus creates a closed position.
- a separators are provided which can separate the yarns or rovings or ribbons in the area of the yarn transfer points. After separation, another layer can be placed, for example, at a different angle.
- the yarns or rovings or ribbons are preferably made of carbon, glass or aramid fibers.
- the yarns or rovings can be splayed on the way between the unwinding station and the yarn transfer point, so that they are neatly clamped next to each other. This can be done for example by multiple deflection around rollers or rods.
- the Fibers or rovings or ribbons already contain binder material or binder material can be applied between the unwinding station and the yarn transfer point or near the pick-up position.
- the binder material can also be applied only to the unfolded or deposited layer. For example by spraying.
- the matrix material may also already be applied, which is then consolidated or cured after forming.
- the fiber preform already contains matrix material in not yet cured or not yet fully consolidated form.
- the several unwinding stations can be designed, for example, as a so-called creel.
- the yarns or rovings can be drawn from bobbins or bobbins.
- Each yarn transfer point receives yarn or rovings from one or more unwind stations.
- Advantageous for the simple apparatus design and to be able to store a particularly uniform layer with little fiber shift it is when the grippers are arranged alternately in an upper plane and in a lower plane and the two planes are parallel to each other. That all adjacent grippers each have the same height offset to each other. This results in the clamping an upper part position and a lower part position, which come together when dropping to a closed position.
- the paths of the grippers are substantially linear and / or horizontal.
- the apparatus implementation is further simplified.
- the height offset between two adjacent grippers based on the position of the gripped yarns or rovings or bands, between 10 and 300 mm, preferably between 20 and 100 mm. Too small an offset allows only very slim gripper that can not muster a high clamping force. Too large an offset leads to a higher risk of shifts when moving to and from one level.
- the pick-up positions of adjacent grippers in particular of each respectively adjacent gripper, can preferably be arranged offset to one another in the direction of the path. It makes sense to then the respective adjacent yarn transfer points are offset in the direction of the paths to each other, the space required in the height is larger for the gripper at the pickup due to the necessary opening movement when picking up the yarns or rovings or ribbons. Offset in the direction of the path of the respective gripper means that the grippers pick up the yarns or rovings or ribbons in a horizontal direction at offset points. As a result, the grippers are not on top of each other at their pickup positions and can thus be opened well even at a lower height offset, without them colliding with each other.
- a preferred size range for the offset of the pickup position of adjacent grippers in the direction of the path is 10 to 500 mm, more preferably 10 to 100 mm.
- the gripper comprises the head on which the yarns or rovings or ribbons are clamped.
- each gripper can be attached to a respective guide device, which is designed as a carrier made of fiber-reinforced plastic or aluminum.
- the guide device couples the gripper to a drive system so that the gripper can be moved.
- the carrier is, for example, rod-like executed as a pipe or rectangular profile.
- the carrier is very light and yet rigid, which allows a high position accuracy in the process and a fast moving.
- the grippers preferably each have a clamping width of 20 to 500 mm, particularly preferably 30 to 100 mm. In particular, it may be advantageous that all grippers have the same clamping width. If the clamping width is too great, the clamping forces become too high and thus the grippers and the guide means become too heavy, and the flexibility for producing various shapes is restricted. With very small clamping width too many grippers are needed, which makes the device too expensive. The specified range offers sufficient flexibility without too much equipment. Depending on the component, the grippers may also have different clamping widths.
- the clamping width of the grippers is preferably 5 to 100 mm, particularly preferably 10 to 50 mm wider than the band to be clamped. So the band can be clamped securely.
- the yarns or rovings clamped by a gripper are also considered as a band.
- the device according to the invention may comprise a table which is rotatable about an axis substantially perpendicular to the paths and which may be raised and lowered substantially perpendicular to the paths. By lifting the table can be brought, for example, in the plane of the spanned yarns so that they can be better placed on it. Turning the table allows you to place several layers at different fiber angles for a load-oriented production of the fiber preform, for example below +/- 30 ", +/- 45 °, +/- 60", +/- 90 " preferably rotatable by +/- 30 "to +/- 90".
- a first mold may be present, which between the pick-up position and the Maxi times position of at least some grippers can be brought, in particular so that thereby the spanned yarns or rovings or ribbons are draped over the first mold.
- the first mold may for example be mounted on the table and raised and lowered over this, as well as rotated.
- the further mold may be formed as a hood, which forms a counter-mold to the first mold and presses the fiber layer to this.
- the further shaping tools can also be designed as a plurality of punches or partial hoods, which press the fiber layer only at specific locations on the first molding tool, for example in concave areas or at edge transitions of the mold.
- the other molds can also be made to be movable in different directions and inclined relative to the vertical in order to be able to press the fiber layers of the desired shape correspondingly to the first mold.
- the first and / or one or more further molding tools can be heated. Likewise, however, the first and / or one or more further molding tools can also be cooled in order to re-solidify already preheated binder material during shaping.
- a heating device in particular an IR radiator device or a heated plate, can be provided, which heats the fibers or rovings or bands during or after clamping.
- binder material can be activated or the clamped layer can be made more deformable.
- FIG.1 - 4 preferred embodiment of a device according to the invention
- FIG. 7 shows a detail of another gripper arrangement according to the invention (top view)
- FIG. 8 shows a detailed view of the further gripper arrangement according to the invention (front view).
- the figures are described in more detail below.
- the devices according to the invention shown in the figures are described for the processing of rovings. But they can be used in the same way for yarns or ribbons.
- the devices are suitable for carrying out the following method steps successively or partly parallel to each other:
- fibers such as e.g. made of carbon (carbon), glass, or aramid or other fibers.
- a matrix material for the fiber reinforced plastic e.g. thermoplastic or thermosetting plastic in question.
- the binder material may be thermoplastic, thermoset or adhesive. It may already be present as a hybrid or hybrid roving, i. individual fibers or yarns are made of binder material, or it can be spanned along with the rovings from the gripper or it is applied to the draped rovings or sprayed.
- FIGS. 1-4 show a preferred device according to the invention.
- Fig. 1 and 2 the picking up of the rovings using the gripper is shown. Once in side view and once in plan view.
- the basic structure of the device is also recognizable.
- the provision of the yarns or rovings takes place via a multiplicity of unwinding stations 1, 2, 3, 4, in which the fiber material is provided in the form of bobbins or bundles of yarn (so-called bobbins) and which are arranged next to one another, behind one another or one above the other in several rows 1, 2 are arranged.
- the coils may also form an upper and a lower row as shown in FIG.
- the beginnings of the yarns or rovings 20 are shown schematically only in the respectively used area for the unwinding stations 3,4 used. All other beginnings are threaded to the corresponding yarn transfer points 13,14 so that they can be detected by the associated grippers in pick-up position 7,8. The location of the pick-up positions is marked with 1 1. Such a thing is also called a creel.
- the adjacent grippers 7 and 8 are offset from each other in height. Gripper 7 is arranged in an upper plane, gripper 8 in a lower plane. On the other side of the device, the grippers 5,6 are shown in their maximum positions 12, Also in the grippers 5,6 adjacent grippers are arranged offset in height to each other.
- the clamping width of a gripper is slightly wider than the actual width of the rovings clamped by a gripper. Even if only equal width gripper are shown, of course, grippers with different widths are possible.
- the grippers do not necessarily have to have their maximum and pickup positions in line.
- the grippers are each coupled to a guide device 9,10.
- the guide device may be, for example, a rod or a carrier. Preferably, it is designed as a carrier made of fiber-reinforced plastic, since even with long travels a high bending stiffness with low weight is possible.
- the guide devices are connected to a drive system. In the apparatus shown, the grippers are moved parallel to each other, on linear, horizontal paths. They can be moved individually.
- the grippers 7, 8 are in pick-up position and pick up the rovings at the yarn transfer point assigned to them by gripping their beginnings.
- Several unwinding stations can be grouped together and assigned to a gripper.
- a gripper can grab several rovings together. In any case, at least as many unwinding stations as grippers should be provided.
- Each gripper is assigned a yarn transfer point.
- Fig. 2 it can be seen that the yarn transfer points 13 are arranged in an upper plane and the yarn transfer points 14 in a lower plane.
- a possibly existing spreading device or a binding device, which may be provided between the unwinding station and the gripper, are not shown separately.
- the binding device can also be arranged in the region of the lifting table.
- a first mold 18 is provided on a lift table 17, wherein the mold 18 can be rotated on or with the lift table 17.
- another mold 16 which is designed as a hood, in the down position so represented outside the paths of the gripper.
- the further mold 16 is not shown in plan view. And a corresponding movement or lowering device for the further mold 16 is not shown separately.
- the further mold can also be constructed in several parts, for example, of several stamps. On the first mold 18, an already deposited layer 23 of rovings is shown.
- FIG. 3 shows the device in plan view when mounting the rovings 21st
- the grippers are in an intermediate position 15. Depending on the shape, the grippers can also be moved to different intermediate positions, so that a close-contour clamping with little waste of expensive fiber material is possible. It becomes clear how a closed layer of rovings with a uniform density can be clamped simultaneously by the adjacently arranged adjacent grippers.
- a heating device e.g. one or more IR emitters, be provided to heat applied binder material and thus to activate.
- the lifting table 17 has moved upwards, so that the rovings 22 are draped over the first forming tool 18.
- the further forming tool 16 has moved together with the first forming tool 18, so that the rovings 22 are correspondingly shaped.
- the first mold 18 and / or the further mold 16 may be heated to heat binder material.
- the first mold 18 and / or the further mold 16 may also be cooled in order to cool already heated binder material and thus to fix the mold.
- FIG. 5 shows a further preferred device according to the invention when collecting the rovings.
- the essential difference to the apparatus shown in Figures 1-4 is that the adjacent grippers 7 'and 8' have a horizontally offset picking position 11 'and 11'.
- the picking positions are offset in the direction of the gripper moving path.
- the Garnschreibgabestellen 13 'for the upper gripper 7' is also horizontally offset from the yarn transfer point 14 'of the adjacent lower gripper 8'.
- the grippers can be arranged in height with little offset and still, without obstructing each other, be opened wide.
- FIG. 6 shows grippers 24 on an upper level 30 and vertically offset therefrom grippers 25 on a lower level 29.
- the level of the grippers denotes the position of the respectively clamped rovings.
- the grippers have a larger clamping width than the width of the clamped in a gripper rovings 26,27. Due to the offset in height, the grippers 24, 25 can overlap accordingly, so that in the plan view, a closed layer of rovings can be generated. No elaborate control in the transverse direction when depositing is necessary, but only a mechanical alignment of the gripper in the device.
- FIGS. 7 to 8 explain the advantage offered by the picking positions for the grippers, which are additionally offset horizontally from one another.
- Fig.7 shows the plan view
- Fig.8 the front view. Guiding devices and yarn transfer points are not shown.
