Description

The present invention relates to a tape laying apparatus according to the preamble of claim 1 and to a tape laying method for constructing a laminate for, for example, automotive components according to the preamble of claim 11.

Fiber composite applications have continued to increase over the past decades, especially when viewed as a cost-effective alternative to metallic materials, with the benefits of design freedom and application-specific formulation capabilities. Specifically, the material CFK (carbon fiber reinforced plastic) has an extremely high lightweight potential, while it is characterized by its high strength and very high structural rigidity. The latter is an important criterion in automotive engineering, for example.

Therefore, today's development activities for fiber composite processing equipment ranges from pure machine development to turnkey production systems. The former usually include preform manufacturing units, press units and optionally injection units and post-processing units - the latter the corresponding automation for preform handling, tool cleaning, component removal and the like.

The automatable production of the preform represents a key technology in the production process of continuous fiber reinforced fiber composite components to realize an efficient mass production with reproducible stable component quality. But also in so-called hybrid components, ie compression molded sheets, which are mainly pressed with carbon fiber semi-finished products to reinforce critical stress zones in addition All production units must be able to integrate plant and control technology if sufficient productivity is to be achieved.

For the production of continuous fiber-reinforced components, predominantly textile fiber semi-finished products such as fiber impregnated with a binder (hot melt adhesive) and / or with a matrix partially or completely impregnated fiber yarns and / or fabrics (so-called prepregs) such as fiber fabrics, fiber knits, fiber fabric or fiber mats used. The matrix of fiber-reinforced plastics has the task of embedding the heavy-duty fibers (supporting function) and completely filling their intermediate space (blocking function).

In principle binder materials and / or matrix materials can be used materials from the groups of thermoplastics or thermosets and optionally additional elasticizing components, such as elastomers, which in the strength, the maximum elongation, the operating temperature, the processing speed and the Distinguish chemical resistance. Thermosetting molding compounds can be plasticized by the action of temperature, are malleable at this moment and then cure irreversibly under pressure and temperature. In contrast to the thermoplastics, the elastomers and thermosets (also called thermosets) after processing, d. H. in the ready-to-use state, of more or less strongly cross-linked macromolecules, which are generally neither fusible nor soluble.

From these semi-finished products, which are available as rolls or sheets in standard formats, blanks are produced in a cutting process, which usually line the formed component completely. When cutting the blanks, depending on the component geometry, a significant cutting waste is generated that can not be processed and significantly reduces the efficiency of this process.

To improve resource efficiency, continuous fiber-reinforced components can be produced substantially less waste or without wastage via processes that have become known as tape-laying methods. In particular, the use of tapes made of thermoplastic continuous fibers proves to be a very attractive process variant. In particular, the laying of the fibrous composite materials, which are usually present as a tape, for constructing a laminate presents a special challenge.

By "tape" in the context of the present invention is preferably meant any type of sheet material, in particular a prepreg material having, for example, a width of between 30 and 200 mm, which is suitable for being laid down by means of a tape laying device. By "prepreg material" is meant herein in particular fiber yarns (rovings), fiber scrims and / or fiber webs, which are wetted with a binder and / or impregnated with a matrix, for example a thermoset matrix or thermoplastic matrix, partially or completely impregnated, in particular preimpregnated.

The "fibers" are in particular carbon fibers, but in the same way also for glass fibers or other, in particular artificially produced, fibers applicable.

The tape can be arranged on a carrier material, in particular a carrier film or a carrier paper, which during the laying of the tape to build up the laminate of the Dissolves carrier material, wherein the carrier material removed by means of a suitable device of the tape-laying device, for example, wound, is. However, it is also preferable to use tapes which no longer require carrier materials.

For the processing of tapes is known to deduct these from a spool or roll to cut to length and place on a laying table or already laid on the laying table tapestry. When a tape strip is deposited, it is connected pointwise to the underlying tape layer via a number of ultrasonic welding heads.

For processing tapes and for carrying out a tape laying process, automatic devices are often used which are able to deposit a structured tape. Known are in particular so-called. Tapelegevorrichtungen, which in the present case, for example, a so-called. Fiber placement device is to be understood.

An exemplary tape-laying device is from the document WO 2014/083196 A1 which describes a tape laying apparatus configured with two laying head units. The laying head units are arranged so that they are accessible to a single laying table. The laying head units are independent of each other and each configured with its own material feed unit, cutting device, gripping means with associated linear drive, guideways and tape stitching unit. In this configuration, a belt section can be drawn to length, positioned in guideways and stapled in position with the first laying head unit on the part to be produced, while at the same time the length of the next belt section being positioned on the second laying head unit in the guideways. After the first band portion is tacked by the first laying head unit, the laying table conveys the part to be produced to the second laying head unit, during which the next band portion is prepared and positioned to be adhered to the part to be produced.

The US 8,048,253 B2 also describes a tape laying apparatus with a laying head, wherein a tape tape material is fed to a cutting device which separates a tape strip which is then placed with the laying head on the working surface of a laying table. The tape tape material and the separated tape strip are guided in the laying head in each case in guide rails which are arranged on both sides of the tape or the tape, wherein the edges of the tape or of the tape in grooves provided in the guide rails, being held. The document also describes that several laying heads can be provided, so that it is possible to deposit several tapes or tapes at the same time.

In both of these known Tapelegevorrichtungen has the disadvantage that because of the only lateral guiding and holding the tapes by means of the guide rails to be processed tape tape material must have a sufficiently high internal stiffness, so that it does not happen that the tape tape sags and falls out of the guide rails. This may represent an undesirable limitation on processable materials, thicknesses and / or widths.

Also, because of the only relatively loose holding the tapes by means of the lateral guide rails, the cycle time can not be increased arbitrarily. This is because, if the laying head is lowered too rapidly, and the tape strip has to be moved rapidly against the resistance of the surrounding air, the risk of the tape "blowing" and falling out of the guide rails becomes significant can increase.

The document describes the laying of large-area fiber fabrics WO 2012/156524 A1 a method for transporting a cut out of a flat fiber fabric fiber contour in the course of the production of fiber-reinforced plastic moldings. A fiber contour is cut out on a cutting table. Subsequently, a suction gripper moves over the fiber contour and brings a transport plate into contact with the cut-out fiber contour. By means arranged on the transport plate suction devices, the fiber contour is fixed to the transport plate and lifted from the cutting table. The suction devices operate according to the Bernoulli principle, whereby air flows of the suction devices arising from the compressed air supply are led away from the separating section of the fiber contour. The suction pad is attached to a manipulator such as an industrial robot. A similar principle of a suction gripper, which is used for receiving large-area fiber fabrics attached to an industrial robot, is also from the document DE 10 2013 208 778 A1 known, which describes a suction gripper in the form of a rod system arrangement of angularly crossed and parallelogram-like slidable rods. Suction grippers, which use a Coanda effect, are variably positionable on the grid structure.

It is therefore an object of the invention to provide an improved tape laying apparatus and an improved tape laying method which overcomes the above drawbacks.

In particular, it is an object of the invention to provide an improved tape laying apparatus and an improved tape laying method which permit rapid laying of components or component layers with a short cycle time.

It is yet a further object of the invention to provide an improved tape laying apparatus and an improved tape laying method which can be used flexibly and rapidly for efficiently laying down tape of varying widths.

It is a still further object of the invention to provide an improved tape laying apparatus and an improved tape laying method which can be used with low equipment costs and operating costs.

The above objects and other objects are achieved by a tape laying device comprising a feeding device for feeding at least one tape to a downstream laying device, which is arranged for receiving supplied tapes and placing the tapes on a laying table, wherein the laying device and preferably the feeding device each have a planar Transport element, wherein the laying device and the feeding device for transferring at least one tape from the feeding device to the laying device are vertically arranged at different heights, so that they form a vertical distance, and the laying device and the feeding device continue to overlap in a transfer area such that tapes be passed from the feeder to the laying device.

In a preferred embodiment, it is provided that the transport of the tapes in the laying device takes place in a suspended manner and in the feed device and / or that the laying device is arranged in the transfer region above the feed device. In this case, above or above the supply device, on the one hand, an arrangement of the laying device vertically above the supply device. In an inclined feed device and laying device referred to above or above that the movement of the tape has a vertical component in addition to a horizontal component.

With the present invention, it is made possible to simplify the transport of tapes in a tape laying device, since the tapes are now no longer guided in guide rails, but on a flat transport element, which receives the tape surface, preferably the entire surface. Thus, tapes can now be processed regardless of their properties such as thickness, width, rigidity in a Tapelegevorrichtung. By forming a transfer region in which the laying device and the feed device overlap, it can also be ensured that the at least one tape can also be taken over safely and without damaging the tape per se, such as, for example, the fiber structure or the surface. The distance of the feeding device and laying device depends on the fact that the tapes to be transported can also be safely taken over and is preferably slightly larger than the thickness of the tapes.

In particular, the planar transport element of the laying device and / or the feed device can be designed as a circulating around pulleys conveyor belt. Alternatively or in combination, the planar transport element of the laying device and / or the feed device can have a plate-shaped bearing surface, which can be moved in and against the transport direction of the tapes. The flat transport element holds or carries the tape over its entire width on the transport element. The transport is thus independent of the properties of the tape and even pliable tapes can be easily transported. Especially with the use of circulating conveyor belts, a continuous laying process can be achieved without a loss of time by moving from a pickup position to a stored position and back to a pickup position, since the conveyor belt continuously rotates.

Preferably, the laying device and / or the feeding device to a vacuum device, wherein the at least one tape by means of the negative pressure generated by the vacuum device to the planar transport element of the laying device and / or feeding device is sucked and held on the transport element holding. By using a vacuum device, the tape can be sucked to the transport elements and also stick to these and is held as long as there is a negative pressure. In the feeder, a vacuum device is not necessarily required because the lying transporting tapes is possible even without vacuum or negative pressure. By using a vacuum device, however, the tape remains adhering to the transport element during acceleration of the tape or of the conveyor belt or due to air turbulence occurring in the surroundings and, moreover, in a defined position on the transport element. Due to the precisely defined position of the tapes, higher levels of leweighting can be achieved when storing the tapes and ultimately at the components to be produced.

It should be noted that herein the term vacuum is not used in the sense of an ideal, complete vacuum, which would correspond to a complete absence of air or other gases. This applies in particular to the vacuum generated in the vacuum device. Rather, the term vacuum is used herein in the sense of negative pressure, which in particular is sufficiently pronounced in order to be able to safely comply with a desired and / or required minimum holding force.

The generated negative pressure relative to the environment may be in the range of a few 10 mbar, preferably between 20 and 100 mbar, particularly preferably between 30 and 60 mbar.

In a particular embodiment, the vacuum devices in the feed device and in the laying device form an overlap in the transfer area, wherein the overlap is preferably less than 20% of the length of the transfer area, preferably less than 10% and particularly preferably less than 5% of the transfer area, or wherein the negative pressure means of the feed device and the laying device are arranged adjacent to each other in the transport direction and the overlap is zero. An overlap of the vacuum means of feeder and laying means allows a safe transfer of the tapes from the feeder to the laying means. The overlap of the vacuum devices should be limited to a fraction of the transfer area, because on the one hand, in the region of the overlap of the vacuum devices, forces from the supply device and, on the other hand, forces from the laying device act.

Advantageously, the tape laying device further comprises a material supply unit and a cutting device, wherein by means of the material supply unit, a tape tape material of the supply device is supplied and in the cutting device, a cutting of the tape tape material to tapes. The tape tape material can be continuously fed to the tape laying apparatus and thus enables continuous operation of the apparatus. In addition, the cutting or cutting is done to the necessary without material loss in contrast to the use of pre-assembled tapes.

Alternatively or in combination, it may be provided that the laying device for depositing tapes on the laying table is lowered and / or that the laying table is movable or rotatable in all spatial directions and in particular to the laying device to be moved. To lay down the tapes, either the laying device or the laying table can be moved individually, but also together.

Preferably, the movement of feeding device and laying device is coupled or the feeding device is movable out of the transfer region during the lowering of the laying device and / or can be tilted away from the laying device by an angle, so that the laying device deposits the tapes on the laying table freely and without impairment can. By forming a transfer area, it may be possible that when depositing the tapes affect the feeding device and the laying device and the laying device can not be moved to the desired extent. For this purpose, it is advantageous if either the feed device and the laying device move together and thus the distance between the two devices remains constant. Alternatively, the supply device and the laying device can be controlled separately and individually, and their individual movements can be regulated and controlled by a control device.

In particular, a first supply device and a second supply device are arranged, wherein the first supply device is arranged in the transport direction in front of the second supply device and wherein the second supply device is designed as an acceleration device for accelerating tapes. In addition to the formation of the second feeding device as an acceleration device, the first feeding device can be designed as a cutting device in which the tapes are cut from the strip material. The two feeders thus decouple on the one hand an almost continuous cutting process, since the supply of tape tape for the purpose of a clean cut to tapes should be stopped at each cut, and on the other hand, a continuous feeding and laying process. The acceleration device can serve to arrange the tapes in the defined position and at a defined distance from one another before they are deposited on the laying table.

Alternatively, the tape-laying device is characterized in that the distance is less than 5 mm, preferably less than 4 mm, preferably less than 3 mm, more preferably less than 2 mm and most preferably less than 1 mm. The smaller the distance between the feeding device and the laying device, the easier it is to take over the tape from the laying device. In particular, by a distance which is slightly more than the thickness of the tape, the emergence of defects in the tape itself, such as kinks of the tape or the tearing of the continuous fibers, can be avoided in the tape.

Furthermore, it can be provided that the negative pressure in the laying device is greater than the negative pressure of the feeding device, so that in the formation of an overlap of the vacuum devices of the feeding device and laying device, the tape can be sucked and transferred to the laying device without the vacuum in the supply device interrupt.

As a further solution to the above and other objects, there is provided a tape laying method for laying tapes comprising the steps of: feeding at least one tape to a laying means by means of feeding means; Recording and placing the at least one tape on a laying table by means of a laying device, wherein the laying device and preferably the feeding device each have a flat transport element, wherein the laying device and the feeding device overlap in a transfer area and form a distance from each other, so that the at least one tape of the feeding device is transferred to the laying device.

Alternatively, the method is characterized in that the tapes are transported suspended in the laying device and lying in the feeding device.

Preferably, the planar transport element of the laying device and / or the feed device is designed as a circulating around pulleys conveyor belt. Alternatively or in combination, the planar transport element of the laying device and / or the feed device has a plate-shaped bearing surface, which can move in and against the transport direction of the.

It may further be provided that the laying device and / or the feed device have a vacuum device, wherein the tapes are sucked by means of the negative pressure generated by the vacuum device to the planar transport element of the laying device and / or feeding device and transported to the transport element.

In a preferred embodiment, the supply device tape tape material is fed via a material feed unit, wherein the tape tape material is cut in the feeder by means of a cutter into tapes.

Alternatively or in combination, the tape laying method is characterized in that the laying device for depositing tapes is lowered onto the laying table and preferably lifted again after depositing and / or that the laying table can be moved and / or rotated in all spatial directions and in particular on the laying device for Laying down tapes can be moved. To place the tapes on the laying table either this can now be moved to the laying device or the laying unit on the laying table or a combination of both. The choice of which device to which, how far to move depends on the inertia of the individual devices and on which option the shortest cycle times for laying a tape offers.

The feeding device is preferably coupled to the movement of the laying device. Alternatively, during the lowering of the laying device, the feeding device can be moved out of the transfer region and / or tilted at an angle away from the laying device, so that the laying device can deposit the tapes on the laying table freely and without being affected by the feeding device.

Advantageously, a first feed device and a second feed device are arranged, wherein the first feed device in the transport direction in front of the second feed device ( 20a ) and wherein the tapes on the second feeding device are accelerated.

Alternatively, the tape laying method is characterized in that the distance is less than 5 mm, preferably less than 4 mm, preferably less than 3 mm, more preferably less than 2 mm and most preferably less than 1 mm.

Further advantageous measures and embodiments of the subject matter of the invention will become apparent from the dependent claims and the following description with the drawings. The invention will be described below in detail with reference to the figures.

2 a schematic representation of another device according to the invention for tape laying;

3A and 3B an enlarged view of a transfer area;

4A to 4C various embodiments for depositing tapes.

In the 1 is a tape device 1 according to one embodiment shown in a schematic cross-sectional view. As in 1 is shown in the Tapelegevorrichtung 1 a tape tape material 3 For example, on a spool 12 is provided wound by means of a material supply unit 10 from the coil 12 unwound and one of the material feed unit 10 downstream feeder 20 fed. For this purpose, the material supply unit 10 a pair of drive rollers 11 comprising a roller drive, also referred to as lack drive, form, for the transport of the tape tape material 3 provides. The drive rollers 11 are thereby driven by one or more motors (not shown) under the control of a control device (not shown), so that the tape tape material 3 at a desired speed and / or length into the feeder 20 "Pushed" and fed in such a way. The sink 12 is thereby independently driven by one or more motors (not shown) and winds the tape tape material 3 continuously from the coil 12 from. Furthermore, in the material supply unit 10 one or more pulleys 13 arranged as well as a dancer system 14 , which serves as a buffer for the tape tape material, for example when a coil 12 must be replaced. The dancer system 14 causes by means of a spring system a tape supply. Later on, the tape tape material 3 in the feeder 20 from a cutting device 24 to individual tapes 2 . 2a . 2 B . 2c cut. For clean cutting of tapes 2 It is necessary that the roller drive 11 short stops and the supply of tape tape material 3 to the feeder 20 is briefly stopped. To still allow a continuous unwinding of the spool, the dancer system 14 compensate for this short deceleration or stopping of the belt movement.

In the cutting device 20 the feeding device 20 becomes the tape tape material 3 by means of a cutting means, for example designed as a cutting blade, cut to remove from the tape tape material 3 individual tapes 2 . 2a . 2 B . 2c to separate a desired length. The cutting blade is angularly adjustable so that not only cuts across the tape direction or to the transport direction 60 of the tape material band 3 can be performed, but by means of a corresponding adjustment of the cutting blade by an angle of, for example, ± 45 ° relative to the transverse direction of the tape tape material 3 which extends along its width, also tapes 2 . 2a . 2 B . 2c can be cut off, which are cut in a corresponding desired angle.

After the tapes 2 . 2a . 2 B . 2c such in the cutter 24 from the tape tape material 3 separated and singled, the tapes are 2 . 2a . 2 B . 2c on a laying device 40 feeds and handed over to them.

The laying device 40 is over a lay table 50 arranged and can be in the vertical direction relative to the laying table 50 be moved so that the laying device 40 one single tape each 2 . 2a . 2 B . 2c on the laying table 50 can place and place. For example, a linear guide (not shown) may be provided by means of which the laying device 40 in the vertical direction on the Legetisch 50 can be lowered to the tapes 2 . 2a . 2 B . 2c on a working surface of the laying table 50 , or one previously on the work surface of the Legetisches 50 trained tapestry structure, and if necessary, short and easy to press. After dropping the tape 2 . 2a . 2 B . 2c becomes the laying device 40 raised again to a next tape 2 . 2a . 2 B . 2c take. It should be noted here that for the purposes of this document, both placing and removing a tape 2 . 2a . 2 B . 2c on the working surface of the laying table 50 , as well as the laying down of a tape 2 . 2a . 2 B . 2c on already before on the Legetisch 50 discarded tape 2 . 2a . 2 B . 2c , in particular on a previously formed stacking layer, as placing and depositing the tape 2 . 2a . 2 B . 2c on the laying table 50 to be understood.

To lower the laying device 40 to allow in the embodiment of the 1 be provided that the feeding device 20 also and together with the laying device 40 vertically lowered and raised. This can be done in particular by the fact that the feed device 20 and the laying device 40 to a unit called a laying head.

Alternatively, it is also conceivable, the laying head or the laying device 40 form stationary, and the laying table 50 liftable, so that the filing of the tape 2 . 2a . 2 B . 2c the laying table 50 is raised. Incidentally, it is preferable that the laying table 50 under the control of the control device (not shown) about a vertical axis of rotation Z can be rotated, and / or in the horizontal direction in the x and / or y direction can be moved to a desired relative positioning of the tape 2 . 2a . 2 B . 2c relative to the laying table 50 to enable.

To increase the laying rate, it is provided in particular that several tapes 2 . 2a . 2 B . 2c be simultaneously, that is, in particular at the same time and multi-track handled, with such a parallelization advantageous the number of tapes laid 2 . 2a . 2 B . 2c multiplied accordingly per sequence.

In relation to 2 is another tape device according to the invention 1 shown. The material feed unit 10 is identical to the structure described above. In addition to a feeder unit 20 is now a second feeder unit 20a in the tape device 1 arranged, wherein the second feed device 20a in the transport direction 60 after the first feeding device 20 is arranged. Between the two feeders 20 . 20a There is now the possibility of faulty tapes 2 . 2a . 2 B . 2c or also waste material before the laying device 40 from the Tapelegevorrichtung 1 auszuschleusen. The arrangement of two or more feeders 20 . 20a also has other benefits. Thus, the first supply device 20 as a cutting band with the cutter 24 be formed, on which the tape tape material 3 to tapes 2 . 2a . 2 B . 2c is isolated. The second material feed unit 20a , can be used as an acceleration device, for example with an acceleration belt 21a be formed so that the previously cut tapes 2 . 2a . 2 B . 2c on the one hand quickly from the first feeder 20 can be deducted. On the other hand, by the formation of the second feed device 20a as acceleration device the tapes 2 . 2a . 2 B . 2c be brought to a certain distance from each other and thus isolated. By separating the individual tapes 2 . 2a . 2 B . 2c finally better and each independently from the laying device 40 be taken over.

The process of laying the individual tapes 2 . 2a . 2 B . 2c finally runs in again 1 already described.

As in the 1 and 2 shown are the laying device 40 , the feeder 20 . 20a preferred with conveyor belts 21 . 21a . 41 designed as a flat transport element, the respective pulleys 22 . 22a . 42 circulating endlessly. In the feeder 20 . 20a while doing the tapes 2 . 2a . 2 B . 2c lying, that is, on an upper side of the feeding device 20 . 20a on the conveyor belt 21 . 21a transported overhead. On the other hand, the individual tapes 2 . 2a . 2 B . 2c in the laying facility 40 each transported "hanging". For this purpose, the laying device 40 preferably with a vacuum device 43 provided, which with the conveyor belt 41 the laying device 40 connected to that by the conveyor belt 41 Air can be sucked through and so a negative pressure can be built up, for example by a plurality of openings in the conveyor belt 41 are provided, through which the air can be sucked. Due to the resulting negative pressure can be on the conveyor belt 21 . 21a the feeding device 20 . 20a lying, the laying device 40 , supplied tapes 2 . 2a . 2 B . 2c be sucked so that it is on the bottom of the laying device 40 on the conveyor belt 41 is held contiguous. The vacuum device 43 Can be turned off after the tape 2 . 2a . 2 B . 2c on the laying table 50 was placed. In addition to the laying device 40 can also be the feeder 20 . 20a with a vacuum device 23 . 23a be equipped so that despite the horizontal transport of tapes 2 . 2a . 2 B . 2c they can not move in relation to each other.

With reference to the 3A and 3B is now the transfer of tapes 2 . 2a . 2 B . 2c from the feeder 20 to the laying device 40 described in more detail. As already to the 1 and 2 explained comprises the laying device 40 one around pulleys 42 revolving conveyor belt 41 as well as a vacuum device 43 , The conveyor belt 41 is so far provided with openings that by the in the vacuum device 43 generated negative pressure tapes 2 . 2a . 2 B . 2c can be sucked to the laying device and on the transport 41 can be transported adhering or hanging. The negative pressure is in the range of a few 10 mbar, preferably in the range of 20 to 60 mbar. In addition to the laying device 40 is in this embodiment, the feeding device 20 with a vacuum device 23 fitted. That around the pulleys 22 guided conveyor belt 21 should have similar or identical characteristics as the conveyor belt 41 exhibit. The execution of the feeding device 20 Having a vacuum device has the advantage that the tapes 2 . 2a . 2 B . 2c controlled at a defined position on the conveyor belt 21 stay fixed. External influences such as sudden air turbulence or slight vibrations change the position of the tapes 2 . 2a . 2 B . 2c not, causing the laying device 40 that or the tapes 2 . 2a . 2 B . 2c can record at a defined position and location.

The feeder 20 and the laying device 40 form a transfer area 61 in which the two devices overlap. In this case, the supply device form 20 and the laying device 40 a distance A from each other, which is 5 mm, preferably 4mm, preferably 3 mm, more preferably 2mm and most preferably 1mm. The laying device 40 is above the feeder 20 arranged so that the transport in the feeder 20 lying and in the laying device 40 Hanging takes place. In general, it would also be conceivable that the feeding device and laying device are arranged at an angle to the horizontal and the tapes 2 . 2a . 2 B . 2c be promoted in the two institutions down or up. The distance A is in this case as the distance of the conveyor belts 21 and 41 seen, with the distance A on the vertical the plane of the conveyor belts 21 and 41 is measured.

As in 3A shown, are the two vacuum devices 23 and 43 in the transfer area 61 adjacent or with a small distance in the transport direction 60 arranged arranged. The tape 2 . 2a . 2 B . 2c will be until the end of the vacuum device 23 on the conveyor belt 21 the feeding device 20 held and can without any forces of the vacuum device 23 on the tape 2 . 2a . 2 B . 2c act from the vacuum device 43 the laying device 40 be sucked.

Alternatively, it is also conceivable that the laying device 40 to take over tapes 2 . 2a 2 B 2c on the feeder 20 moved or vice versa, the feeder 20 on the laying device 40 moved.

Alternatively, the vacuum devices 23 and 43 the feeding device 20 and the laying device 40 in the transport direction 60 be spaced apart. The spacing of the effective ranges of the vacuum device 23 the feeding device 20 and the vacuum device 43 the laying device 40 can be a few centimeters to a few decimeters. The spacing is preferably in a range of 2 to 50 cm, preferably in a range of 3 to 30 cm, and more preferably in a range of 5 to 15 cm.

In a further embodiment, which in 3B is shown, form the two vacuum devices 23 and the 43 the feeding device 20 and laying equipment 40 in the transfer area 61 an overlap 62 out. The overlap 62 only affects a small part of the transfer area, preferably less than 20%, preferably less than 10% and most preferably less than 5% of the length of the transfer area 61 , By forming an overlap 62 can be ensured that tapes 2 . 2a . 2 B . 2c not without a stop in the feeder 20 or the laying device are guided. This is especially true for very short and shortest tapes 2 . 2a . 2 B . 2c for the safe transition of the tapes 2 . 2a . 2 B . 2c of feeder 20 to laying device 40 significant.

In the 4A to 4C are different embodiments for placing tapes 2 . 2a . 2 B . 2c by means of the laying device 40 on the laying table 50 shown.

Dropping tapes 2 . 2a . 2 B . 2c done by a laying device 40 , which of tapes 2 . 2a . 2 B . 2c from a feeder 20 take over. As in 4A The supply device is shown 20 and the laying device 40 over a connection 70 coupled together so that the feeder 20 and the laying device 40 always perform a common movement at least in the vertical, but also preferably in the horizontal. The connection 70 relates to the feeder 20 and laying device for itself, but has no influence on the movement of the conveyor belts 21 and 41 , which can each be moved independently, in particular at different speeds. The connection 70 can be implemented as a mechanical connection via rods, joints or cylinders and / or as an electronic connection via a common control device for controlling and / or regulating the common movement. Thus, the laying device moves 40 for placing tapes 2 . 2a . 2 B . 2c on the Legetisch 50 To the same extent, the feeding device moves as well 20 , However, this requires that the feeding device 20 and the laying table 50 structurally do not overlap and a joint movement of laying device 40 and feeder 20 allow.

In the 4B are the feeder 20 and the laying device 40 individually movable. Preferably, the two devices are connected to each other via a control device (not shown) to the movements of feeding device 20 and laying equipment 40 to control and / or to regulate, in contrast to the embodiment in 4A do not do the same movements. In the case shown, the feed direction moves 20 against the transport direction 60 around the transfer area of feeder 20 and laying device free to give, so that the laying device freely on the Legetisch for laying tapes 2 . 2a . 2 B . 2c can lower. To record another tapes 2 . 2a . 2 B . 2c from the feeder 20 on the laying device 40 the feeder moves 20 now again in the transport direction 60 on the Legetisch 50 and forms with the laying device 40 a transfer area 61 out.

In 4C is another variant for moving the feeder 20 and the laying device 40 when placing tapes 2 . 2a . 2 B . 2c on a laying table 50 shown. In this variant, the supply device 20 at an angle to the horizontal of the laying device 40 be tilted so as to the laying device 40 the space required to place the tapes 2 . 2a . 2 B . 2c on the laying table 50 to give free. The advantage over the variants of the 4A and Fig. 4B is that the feeding device 20 has to exercise a lesser movement and thus faster again in a transfer position are around the tapes 2 . 2a . 2 B . 2c to the laying device 40 to hand over. On the other hand, the pivot point for tilting the feeder 20 at the other, not shown pulley 22 lie so that the cutting device 24 or other means by the movement of the feeder 20 be influenced by an angle far less than against a complete translational movement of the feeder 20 as in 4B represented and a complete lifting movement of the feeding device as in 4A shown.
