    The invention relates to a manufacturing plant for laying slivers and a method for laying slivers.
    From DE 10 2014 101 445 A1 a method for constructing a laminate and an associated tape laying device is known. In this case, a tape to be deposited provided with binder and / or matrix materials is supplied to a depositing device. The supplied tape is deposited by means of the depositing device until the tape structure corresponding to the laminate structure is obtained from adjacent and successive layers, with tape deposited next to one another defining a stacking of a tape structure. The tape structure is introduced to an ultrasound excitation device and thereby plastically plasticizes the binder and / or matrix materials and thereby interconnects the individual layer layers.
    From DE 10 2014 201 060 A1 a fiber spreading machine for the production of
    Fiber Layers known. The fiber laying machine has a tool table for
    Positioning of a molding tool which is linearly movable in egg ner x-direction by means of an x-carriage and pivotable about a vertical pivot axis. Above the tool table, a fiber laying head is arranged, which is linearly movable by means of a y-carriage and transversely to the x-direction.
    Those known from DE 10 2014 101 445 A1 and DE 10 2014 201 060 A1
    Devices have the disadvantage that the fiber laying with such built devices has a high process time.
    Further devices for producing fiber layers are known from WO 2017/084823 A1, from US 2010/193103 A1, as well as from US 2014/299266 A1.
    The object of the present invention was to overcome the disadvantages of the prior art and to provide an apparatus and a method by means of which the laying of fibers and / or creation of tape structures is simplified.
    This object is achieved by an apparatus and a method according to the claims.
    According to the invention, a production plant for laying slivers is formed. The production plant comprises: a laying device with a unwinding device receptacle and at least two juxtaposed unwinding devices, which unwinding devices each comprise a picking device for picking up a raw material roll and a cutting unit for cutting the sliver; - A storage device with a storage surface for receiving the unrolled from the roll of raw material sliver, wherein the storage surface of the storage device and the unwinding device of the laying device are relatively displaced relative to each other in the direction of laying, whereby the sliver strip on the support surface is unrolled. The at least two Abrollvorrichtungen are each coupled by means of a linear guide with a Abrollvorrichtungsaufnahme the laying device and independently in the direction of release relative to Abrollvorrichtungsauf movement slidably.
    The manufacturing plant according to the invention has the advantage that it is constructed robust and less error-prone. In addition, by means of the inventions to the invention manufacturing plant, the individual slivers are placed in a short process time on the shelf to a clutch.
    Furthermore, it may be useful if the unwinding one each
    Have welding head, which is designed for welding two superimposed slivers. The advantage here is that by this measure the individual slivers of the individual sliver layers can adhere to each other. In this case, it is not absolutely necessary for the welding to have a high durability, but it can be provided that the welding serves for purely stabilization.
    Furthermore, it can be provided that the welding head has at least one Niederdrückkufe and in particular a heating element for heating the Niederdrückkufe. The advantage here is that such a thermal welding head can be simple and beyond a thermal weld can have sufficient stability and can be easily manufactured.
    Alternatively, it can be provided that the welding head for ultrasonic welding is formed in particular by means of Ultraschallontsotorotor or friction welding or for resistance welding using electrical current.
    In addition, it can be provided that the support surface of the Ablagevorrich device is vertically adjustable in a vertical direction, so that the distance of the storage surface is adaptable to the unwinding. The advantage here is that the storage area can be adapted to the respective sliver layer to be laid by this measure.
    Alternatively or additionally, it may be provided that the Abrollvorrichtun conditions are displaced in the vertical direction.
    Also advantageous is an expression, according to which it can be provided that the storage surface of the storage device is displaceable in the transverse direction to the laying direction. The advantage here is that by this measure in a first laying step only every second sliver must be placed and in a subsequent laying step, the intermediate missing slivers can be placed.
    According to a further development, it is possible that the storage surface of Ablagevor direction is rotatable about a rotation axis normal to the storage surface.
    The advantage here is that by this measure the slivers of the individual nen sliver layers can be placed at different angles to each other, for example, to obtain a clutch in the form of a check pattern.
    Furthermore, it may be expedient if each of the individual unwinding devices are respectively coupled to a drive unit, in particular a linear motor, by means of which the unwinding devices are displaceable independently of one another in the direction of the laying. The advantage here is that by this measure, the individual Abrollvorrichtungen can be stopped offset in time to each other to attach the sliver to the shelf, the remaining Abrollvorrichtungen not be braked by the stopping of a rolling device. As a result, the total process time can be shortened. This is particularly advantageous if the sliver layer has a complex outer contour and the start or the end of the individual slivers offset from one another.
    In addition, it can be provided that each of the unwinding devices is associated with an egg n integrated circuit, wherein the individual integrated
    Circuits are coupled to a parent central control. The advantage here is that the individual actuators of the unwinding need not be controlled by the parent central control, but that the computing tasks can be taken in the integrated circuit.
    Furthermore, it can be provided that in the region of the cutting unit a cooling device is arranged, by means of which the sliver can be cooled. By this measure, the sliver can be cooled locally to make it more brittle for the cutting process. This is particularly advantageous if the sliver is made of a tough material.
    According to the invention, a method for laying slivers, in particular using a production line according to one of the preceding claims is provided. The method comprises the following method steps: Provision of a laying device with at least two juxtaposed unwinding devices, which unwinding devices each comprise a picking device for receiving a raw material roll of a sliver and a cutting unit for cutting the sliver, wherein the at least two unwinding devices each by means of a linear guide a Abrollvorrichtungsaufnahme the laying device coupled and are independently displaceable in the direction of release relative to Abrollvorrichtungsaufnahme; - Providing a storage device with a storage surface; - Applying the sliver of a first of the rolling devices on the Abla gefläche the storage device; - Fixing the sliver of the first unwinding on the shelf of the
    Storage device; - Unrolling of the sliver of the first unwinding device by moving the first unwinding device in the direction of laying, wherein the sliver thereby on the
    Abrollfläche is unrolled that it is fixed on the shelf and is removed by moving the first unwinding of this; - Cutting the sliver by means of the cutting unit of the first unwinding device; - Applying the sliver of a second of the rolling devices on the support surface of the storage device; - Fixing the sliver of the second unwinding device on the support surface of the storage device; - Unrolling of the sliver of the second unwinding device by moving the second unwinding in the direction of laying, wherein the sliver thereby on the
    Ablagfläche is unrolled that it is fixed on the shelf and is deducted by the displacement of the second unwinding of this; - Cutting the sliver by means of the cutting unit of the second unrolling device, wherein the individual steps of the first unrolling device and the second unwinding device can be started at different times or at the same time and the first unwinding device and the second unwinding device can be moved independently.
    The method according to the invention has the advantage that the process time for producing a sliver layer can be shortened. In particular, it is provided that the individual unwinding devices can be started shifted in time, but that they are moved independently of each other, so that the laying process for each sliver can be performed individually.
    As a result, on a sliver necessary idle times of Abrollvorrich device are not transferred to other unwinding devices.
    According to an advantageous development can be provided that the
    Faserbänder a first sliver layer directly on the support surface of the Abla gevorrichtung be fixed to an intermediate layer and then the Fa serbänder a second sliver layer is applied to the slivers of the first sliver layer, each of the slivers of the second sliver layer by means of a arranged on the unwinding welding head with slivers of first sliver layer is at least partially bonded cohesively. This has the advantage that the slivers of the individual sliver layers adhere to each other, so that the resulting scrims can be easily manipulated.
    In particular, it may be advantageous if the number of unwinding devices is less than the number of fiber slivers provided per sliver layer and in a first process step only every second sliver of a sliver layer is laid, then the support surface of the depositing device is displaced in the transverse direction to the laying direction and subsequently in a further method step, the intermediate, missing slivers of a sliver layer are laid. The advantage here is that by this measure measure the width of the unwinding devices can be much larger than the width of the individual slivers. As a result, the unwinding devices can be made robust or have all the necessary components. By the second step of interposing the still missing tapes, a complete sliver layer can be laid.
    Furthermore, it can be provided that the residual length of the fiber sliver located on the roll of raw material is constantly monitored and that is calculated before the start of laying the slivers, if the residual length of the sliver located on the raw material roll is sufficient for the upcoming laying process, where necessary, a exchanged in a roll storage raw material roll is exchanged. The advantage here is that can be achieved by this measure that does not go out during the laying process, the sliver on the raw material roll. The monitoring of the residual length of the sliver can be done for example by means of a sensor. Alternatively, the residual length of the fiber sliver can also be determined by calculating the consumption on the basis of the already laid sliver webs.
    In addition, provision may be made for monitoring the inventory of raw material reels in a reel-to-reel, upon which a predetermined minimum of raw-material reels initiates an order process in which a command is sent from the central controller to a computer in a network. The advantage here is that by this measure the stock of roll stock rolls located in the roll storage does not have to be monitored by the machine operator, but that the ordering process is triggered automatically. This measure reduces the risk of machine downtime due to human error.
    Also advantageous is a measure according to which it can be provided that the unwinding devices when fixing the sliver on the support surface of the
    Storage device stopped in the movement or at least greatly slowed down. As a result, the starting position or the end position of the slivers can be determined with exact position.
    Clutches are understood to be an arrangement of a plurality of sliver layers arranged one above the other, it being possible for the individual slivers of the individual sliver layers to be arranged in the same and / or different directions. The individual sliver layers need not necessarily be fixed to one another here.
    For a better understanding of the invention, this is based on the following
    Figures explained in more detail.

Furthermore, it is also possible that the fiber ribbons 2 are formed as preimpregnated fibers which comprise reaction resins which consist of a usually highly viscous but not yet polymerized thermosetting plastic matrix and / or of a thermoplastic polymer matrix or of another matrix. In addition, the fiber ribbons 2 may comprise adhesive layers through which individual sliver layers 3, 4 may adhere to each other.
    The manufacturing plant 1 comprises a laying device 6 for laying the sliver 2 and a storage device 7 for receiving the laid slivers 2. Furthermore, a manipulation device can be provided, by means of which the laid on the storage device 7 slivers 2 and sliver layers 3 are removed from the storage device 7 can.
    The laying device 6 comprises at least two unwinding devices 8, which are arranged next to one another on a unwinding device receptacle 9.

    As can be seen in FIG. 1, the depositing device 7 has a depositing surface 12, on which the sliver 2 unrolled by the unrolling device 8 can be deposited and positioned.
    In order to fix the sliver 2 to the support surface 12, it can be provided that a plurality of passage openings 13 are formed on the support surface 12, at which air is sucked off, whereby a negative pressure can be applied to the support surface 12. In particular, it can be provided that the passage openings 13 are flow-connected to a device for generating negative pressure. Such a device for generating negative pressure can be realized for example by an axial or radial fan.
    In particular, it can be provided that the storage device 7 has a round table, on which the storage surface 12 is formed. The storage surface 12 may be displaceable in a vertical direction 14, so that a distance 15 between the unwinding device 8 and the storage surface 12 is variable. By this measure, the support surface 12 can be adapted to different slivers 2 and to the tray in the respective sliver layer 3, 4.
    Furthermore, it can be provided that the support surface 12 is arranged rotatable about an axis of rotation 16, so that the orientation of the slivers 2, which are placed on the support surface 12, can be changed. Thus, it is possible that in several superimposed layers of slivers 2, these are formed in different orientation directions. For example, this can be achieved a diamond pattern or diamond-shaped pattern.
    Alternatively or in addition to the adjustment of the support surface 12 in the vertical direction 14 may also be provided that the linear guides 17 and thus the unwinding devices 8 in the vertical direction 14 are displaceable.
    The Abrollvorrichtungen 8 are each arranged on a linear guide 17, with means of which they are displaced in the direction of view 18. In particular, it can be ensured that each of the unwinding devices 8 is arranged on a separate linear guide 17. Furthermore, it can also be provided that the unwinding devices 8 are displaceable in the transverse direction 23 relative to each other. Furthermore, it can also be provided that all unwinding devices 8 are displaceable together in the transverse direction 23. As a result, the bandwidths can be adjusted, or the slivers 2 are curvy.
    Furthermore, it can be provided that the Abrollvorrichtungsaufnahme 9 one or more portals 19, on which the individual linear guides 17 are arranged. For the sake of clarity, only one portal 19 is shown in FIG. 1, which is arranged in the region of a first linear guide end 20. Of course, it can also be provided that in the region of the second linear guide end 21 also a portal 19 is formed. In addition, one or more portals 19 can also be formed between the two linear guide ends 20, 21.
    Of course, instead of the gantries 19, all other fastening possibilities for receiving the linear guides 17 can also be formed.
    To move the unwinding devices 8 in the laying direction 18 along the linear guides 17, a drive unit 22 may be formed. In a first embodiment, it can be provided that the drive unit 22 example, is designed as a linear motor, wherein the stator can be integrated directly into the linear guide 17.
    Alternatively, for example, be provided that the drive unit 22 has a traction means which is coupled to the unwinding device 8 and between the two linear guide ends 20, 21 of the linear guide 17 is tensioned. A drive motor can in this case be arranged in the region of one of the linear guide ends 20, 21.
    Of course, the drive unit 22 and a gear or other means, wel che serve to move the unwinding have.
    Furthermore, it can be provided that the support surface 12 in a transverse direction 23, which is arranged transversely to the laying direction 18, is displaceable. For this purpose, a transverse direction guide 24 may be formed. The transverse direction guide 24 can, as shown in Fig. 1, for example, be formed by two linear guides.
    Furthermore, it can be provided that the storage device 7 with a longitudinal direction guide 25 is coupled, by means of which the support surface 12 is displaceable in the direction of release 18. By this measure, the storage device 7 can be moved out of the region of the laying device 6, so that the laid on the support surface 12 scrim 5 can be removed by means of a manipulation device of the support surface 12. The scrim 5 can then be inserted by means of the manipulation device into a mold, in particular a 3D mold.
    In FIG. 2, the unwinding device 8 is shown in a first perspective view. In FIGS. 3 and 4, the unwinding device 8 is shown in further perspective views, wherein in FIGS. 3 and 4 details of the unwinding device 8 can be seen. For the same parts, in turn, the same reference numerals or component designations are used as in the respective preceding figures. To avoid unnecessary repetition, the detailed
    Described in the respective preceding figures or reference. The unwinding device 8 will be described on the basis of a synopsis of FIGS. 2 to 4.
    The unwinding device 8 comprises a clamping unit 26 for fixing the of the
    Raw material roll 11 to be unwound sliver 2 and a cutting unit 27 for cutting the sliver 2. In particular, it may be provided that the clamping unit 26 has a jaw 28 and that the sliver 2 between jaws 28 and a counter-holder 29 is clamped. Of the
    Clamping jaws 28 may in this case be accommodated displaceably on an actuator, such as a pneumatic cylinder.
    Furthermore, it may be provided that the cutting unit 27 is designed in the form of a guillotine, wherein the cutting unit 27 may comprise a cutting blade 30 and a counter-holder 31. The counter-holder 31 of the cutting blade 30 can be arranged next to the counter-holder 29 of the clamping jaw 28, subsequently to this.
    Furthermore, it can be provided that the cutting blade 30 is arranged on an actuator, such as a pneumatic cylinder, whereby the cutting blade 30 can be moved relative to the counter-holder 31 and thus the cutting movement can be performed.
    It is also possible that the clamping unit 26 is arranged in the laying direction 18 relative to the cutting unit 27 slidably on the unwinding device 8.
    Thereby, the clamping unit 26 between an advanced ejection position 32 and a retracted home position 33 are moved back and forth. This is necessary in particular in order to provide, after the sliver 2 has been cut off, a band projection 34 on which the sliver 2 can be fixed for unrolling a further sliver strip.
    Alternatively or additionally, it may also be provided that the cutting unit 27 is displaceable in the direction of laying 18.
    Furthermore, it can be provided that in the unwinding device 8, the roll of material 11 unwound from the roll of raw material 2 is guided by a Umlenkrollenanordnung 35, which has at least one guide roller 36. Seen in the course of the sliver 2, in addition to the deflection roller assembly 35, the clamping unit 26 and the course of the sliver 2 further following the cutting unit 27 may be arranged.
    The sliver 2 has a width 37 which may be between 2 mm and 200 mm, in particular between 5 mm and 100 mm, preferably between 10 mm and 50 mm. Furthermore, the sliver 2 has a band width 38, wel che can be between 0.03 mm and 10 mm, in particular between 0.5 mm and 5 mm, preferably between 0.8 mm and 3 mm.
    As shown in Fig. 3, an optical unit 39 may be provided, which serves for tape detection. The optical unit 39 may preferably be arranged next to the cutting unit 27 on the unwinding device 8, so that by means of the optical unit 39 during the unrolling of the sliver 2, the length of a unrolled th fiber strip can be determined. Furthermore, the optical unit 39 can be designed such that the quality and / or dimensions of the fiber sliver of FIG. 2 can be tested. In addition, the optical unit 39 for
    Identifying the sliver 2 are used. Furthermore, the optical
    Unit 39 for controlling the width of the sliver 2 or to control the run of the sliver 2 serve.
    Alternatively or additionally, it can be provided that in the deflection roller 36 or in the receiving device 10 for the raw material roll 11, a detection or measuring system is installed, by means of which the length of the unrolled strip can be detected.
    Furthermore, it can be provided that in the receiving device 10 for the raw material roll 11, a brake unit is installed, so that the raw material roll 11 can be braked and thereby unwanted unwinding of the sliver 2 can be prevented. By means of the brake unit, the tension of the fiber ribbons 2 can be kept constant. Here, the decrease of the unwinding diameter of the sliver 2 from the raw material roll 11 can be taken into consideration.
    In an alternative embodiment, it can be provided that the receiving device 10 for the raw material roll 11 comprises a drive unit by means of which the raw material roll 11 can be driven or braked as required. As a result, an increased tensile load on the sliver 2 can be withheld at elevated processing speeds, whereby the machining speeds can be further increased.

    Furthermore, a hold-down roller 43 may be provided, which serves for pressing the sliver 2 to the support surface 12. The hold-down roller 43 may also be used to weld the sliver 2 in accordance with the mechanisms described in the welding apparatus.
    In Fig. 5 is a further and optionally independent Ausfüh tion form of the manufacturing plant 1 is shown, again with the same parts of the same reference numerals or component names as in the previous Fi gures 1 to 4 are used. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding figures 1 to 4 or reference.
    As can be seen from FIG. 5, it can be provided that the individual unwinding devices 8 are arranged close to each other in such a way that the individual fiber strips 2 can be deposited on the depositing surface 12 at a predetermined distance from each other, which adjusts the end spacing of the fiber strips 2 in one of the respective ones Fiber band layer 3, 4 corresponds. As a result, a sliver layer 3, 4 can be completed in each case with only one laying process.
    In Fig. 6 is a further and optionally independent Ausfüh tion form of the manufacturing plant 1 is shown, again with the same parts of the same reference numerals or component names as in the previous fi gures 1 to 5 are used. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding figures 1 to 5 or reference.
    As can be seen from FIG. 6, it can be provided that the individual unwinding devices 8 have such a large width 46 or are arranged relative to one another such that a gap is formed between the individual, stored fiber strips 2 during the first laying step. This gap between the individual fiber ribbons 2 can correspond to either the single or multiple bandwidth 37 of the fiber ribbons 2. Of course, in this case also a distance between tween the individual slivers 2 may be provided. Step after the first laying step, the shelf 12 can be moved in the transverse direction 23, so that in a second process step slivers 2 can be placed in the gaps. If the gaps correspond to a multiple of the sliver width 46 plus gap between the individual slivers, then the displacement of the support surface 12 in the transverse direction 23 must also be repeated accordingly.
    Based on a synopsis of Fig. 1 to 6, a possible Verfahrensab run for laying slivers 2 is explained.
    As a starting condition, it may be provided that all unwinding devices 8 are arranged in the region of the first linear guide end 20 of the linear guides 17 and that the depositing surface 12 of the depositing device 7 is empty. The slivers 2 may in this case be accommodated in the unwinding device 8 such that a
    Band approach 34 is disposed at least under the hold-down roller 43.
    In a first method step, the individual unwinding devices 8 can be moved independently of one another in the direction of alignment 18 to the second linear guide end 21. When the respective unwinding devices 8 reach their initial position predetermined for the respective contour to be created, they can be stopped or slowed down in their travel speed.
    In order to be able to detachably attach the band attachment 34 to the support surface 12, the hold-down roller 43 can be pressed against the sliver 2. Additionally or alternatively, a vacuum applied to the support surface 12 who the. This attachment process can be repeated on all unwinding devices 8 independently. Furthermore, it can also be provided that between tween the storage surface 12 and the first sliver layer 3, an intermediate layer, for example, a Teflon film is arranged.
    In a subsequent method step, the individual unwinding devices 8 can again be moved independently of one another in the direction of the second linear guide end 21. Due to the relative displacement of the unwinding devices 8 to the depositing surface 12 and in that the band projection 34 is fixed to the depositing surface 12, the fiber band 2 is drawn off the raw material roller 11 due to the relative movement between the unrolling device 8 and the depositing surface 12.
    When the unwinding devices 8 reach their respective individual end positions, the unwinding devices 8 can be stopped again. Subsequently, the clamping unit 26 can be activated, so that the sliver 2 is clamped. Subsequently, the sliver 2 can be cut off by means of the cutting unit 27. In a further method step, the support surface 12 can be lowered in the vertical direction 14. In a subsequent process operation, the individual unwinding devices 8 can be moved back into their starting position or into the position of their next leg start.
    At the same time or at a later time, the clamping unit 26 can be moved from its basic position 33 into an ejection position 32, so that a new band projection 34 can be inserted under the hold-down roller 43. Furthermore, a fixing unit for clamping the sliver in the region of the hold-down roller 43 may be provided.
    The further method step is dependent on how far the individual unwinding devices 8 are spaced from each other. If the individual unwinding devices 8, as shown in FIG. 5, are spaced apart from one another in such a way that all the fiber bands 2 of the first fiber band layer 3 can already be laid, then the process step for laying the second fiber band layer 4 can be continued with the method step described in more detail.
    If the unwinding devices 8, as shown in FIG. 6, are spaced apart from one another in such a way that, for example, only every second sliver 2 can be laid, then in a subsequent method step the support surface 12 must be placed in
    Transverse direction 23 are moved so that the still missing slivers 2 can be placed on the shelf 12. The actual laying process can, according to the process steps already described who executed the.
    For laying the second sliver layer 4, the support surface 12 can be rotated about the rotation axis 16, so that the slivers 2 of the second sliver layer 4 can be arranged offset at an angle to the slivers 2 of the first sliver layer 3. In addition, the support surface 12 can be displaced downwards in the vertical direction 14, wherein the amount of displacement preferably corresponds to the belt thickness 38.
