The orientation of the webbing is determined via the detection device and can be corrected via the units coupled thereto.

In further embodiments, the at least one device can be arranged and controlled in accordance with the information obtained via the detection device. In example, the webbing may comprise connecting portions for the knit band, which are formed as a weft gap portion or as a coarse-meshed section. About the Erfas sungseinrichtung the position of these sections Festge provides and the at least one effecting device can be moved on the basis of the information obtained.

Furthermore, a correction for the tape production unit can be obtained via the detection device. Defects or deviations in the webbing are obtained via the detection device and sent via the controller to the belt manufacturing unit. The tape making unit can use this information to adjust the manufacture of the webbing.

The system may moreover have a transmission device which is gekop pelt via a propeller shaft with a carriage, wherein the carriage is mounted transversely to the machining direction movable and connected to a Schussfadeneintragseinrich tion of at least one active device for a partial shot on the effective bandwidth. The weft also serves to adjust the width of the effect tape. So For example, by the weft thread, the knit tape may have convex or concave sections. The weft also serves to give the knitted tape stability. Of the

Weft yarn is this ge over the width of the knitted tape leads, with a linear movement is required. The weft insertion device may have an additional base barre, which is movable transversely to the machining direction and stores a weft thread over the effective bandwidth or. brings in. For a transmission of this movement, the Ge drive shaft on a carriage, which is also moved only linearly in the same as the additional base bar. The motion is transmitted to the carriage via the cardan shaft. The propeller shaft is coupled to a rotatable unit of the transmission device and transmits the Rotati onsbewegungen in a linear movement. The carriage ensures that the PTO shaft is designed to be relatively short. As a result, damage to the propeller shaft entgegenge acts. In addition, the propeller shaft can be made more stable, since this has only a small length. Does the Wirkma machine on several effectors, so the addi tional basic bars of each active device are coupled linearly with the Schlit th. For this purpose, the additional basic bars can be coupled to one another.

In further embodiments, the rotatable unit of the transmission device may comprise a groove or guide, in wel cher a receiving portion for one end of the propeller shaft is received storable ver. This can be the width of the supplied weft set.

A shift of this section can be done for example via a separate servo motor.

The transmission device itself can be connected via a servo motor, electromechanically or mechanically coupled to the rotatable units of the knitting machine. A mechanical coupling allows a clocked displacement of addi tional base bar depending on the speed of action.

In further embodiments, the Gurtbahnzuführeinheit can be configured to feed the webbing at an angle between 10 ° and 170 ° relative to the processing direction of Wirkmaschi ne. For this purpose, the webbing feed unit can have both gripping elements which can be displaced in the feed direction and gripper elements arranged rotatably relative to the feed web. The feed unit may be configured such that first the webbing is brought into the processing area. Subsequently, via the Gurtbandzuführeinheit the alignment of the webbing relative to the Bearbeitungsriehtung done.

In further embodiments, the webbing is introduced via the Gurtbandzuführeinheit already in the desired orientation in the processing area. The processing area extends along the processing direction as a function of the orientation of the webbings. Therefore, the least one active device in processing direction is arranged downstream of the processing area.

The system may further comprise at least one sensor device, which is designed to detect marking elements and / or defects in the supplied webbing, where in accordance with the recognized marking elements and / or defects, the supply of the webbing and / or a cutting to length of the webbing are controllable.

Analogous to the detection device, the sensor device can detect errors in the webbing. If a fault is detected, it follows a cutting to length of the webbing and the part of the webbing with the defect is fed via the Gurtbandzuführeinheit a disposal station. Subsequently, the belt takes a tape feed unit a new section of the webbing of the tape making unit and introduces this in the processing area processing.

Instead of defects in the supplied webbing, the webbing to be guided may also have marking elements. Such marking elements may be metals, for example, which can be detected by a sensor device. The Mar kierungselemente give feedback on the cut from the webbing. Such marking elements can also be incorporated in the tape manufacturing unit. For example, stamping elements can be provided here. In further embodiments, a thread can also be incorporated into the webbing unit, which can be detected via a corresponding sensor device. Such threads may be, for example, electrically conductive threads. About these threads later components can be arranged o- to check the webbing or. a technical net be used.

The knitting machine may have a feed device having a beam and arranged on the beam bracket with low holders. About the downholder, the webbing is on held a work table and placed in the working area of at least one effecting device.

The knitting machine can in other forms of execution to have a guide device with grippers, on the supply device to the webbing and / or a sheet of fabric the work of at least one active device can be fed. The grippers can be moved both in the machine direction and transversely to the machine direction. In further forms of execution, the feeding device and / or individual grippers of the feed device are rotatable relative to the machining direction, so that a deviation from an orthogonal orientation of the webbing in the machining direction is enabled. Even after the judge of the webbing at an angle> 90 ⁰ relative to Bear processing direction on the Gurtbandzuführeinheit grippers of the feeder can hold the webbing in this position and perform the at least one active device. In addition to the grabs not only the webbing the Arbeitsbe rich at least one feeding device perform, but also at least one substance hold and lead the work area. In further embodiments, the feeding device may comprise grippers for the at least one material as well as grippers for the webbing, the orientation of the material being different from the orientation of the webbing.

The mobility of the gripping elements relative and transverse to the processing direction makes it possible to change the distance between the gripper zuei nander. As a result, a provision of different Net zgeometrien with different Bandöff calculations is improved because the gripper always the webbing on the edge a workspace. The grippers also follow the position of the at least one active device. Before preferably, the gripper and the control device Steue tion technology coupled together.

The above object is also achieved by a method for producing a technical network using egg ner system according to the Ausführungsbei described above Ausführungsbei, wherein in the tape making unit, a webbing is produced, which is fed to the knitting machine via the Gurtbandzuführeinheit, and wherein the knitting Machine supplied belt over the at least one We device is forfeited in a connecting area with yarn sheets.

The webbing can be fed at an angle between 10 ° and 170 ⁰ relative to the processing direction of the knitting machine. This allows the provision of technical networks, wherein the orientation and shape of the openings in the tech nical net z can take place diamond-shaped.

The tape making unit enables the provision of various webbings which can differ in both their type of binding and their width. In addition, for example, electrically conductive threads can be processed, which enable subsequent contacting with electrical elements. Furthermore, already colored threads in the tape manufacturing unit can be fed to who. It also provides an opportunity, in addition to supply several ge dyed threads and / or strips and a plurality of differently colored ge threads and / or tapes, both in the 0 ° and 90 in ⁰ direction. The feeder refers to this the production and thus production of the webbing. As a result, a webbing is made, which is already pre-dyed. This further improves the online process for the production of technical networks.

In addition, it is also conceivable to supply already coated Fä the tape making unit.

The partial shot for the produced by the at least one device Wirkeinrich knitting can be done in accordance with the training of the webbing. The technical network can have both varying distances of the individual belt and impact belts zueinan of as well as knits and straps that include convex or concave shapes. This allows the provision of essentially round openings in the technical network.

The coating and / or dyeing by the coating unit and / or assembly by the clothing unit can take place offline or online. In a preferred embodiment, the processing of the technical network was done online. This allows the provision of a tech nical network based on threads that are fed to the respective compo nents up to a ready-made technical network. For this purpose, the system may have a Wickeleinrich device that winds up the confection ned technical network after assembly and provides for further transport port to the customer. In alternative embodiments, the technical network can also be merged after fabrication. Merging is suitable for networks of different sizes. The technical network can then be provided with other elements, such as hooks. By the Favor te use of non-knitted webbing, d. H . Web, crochet or knit ribbons, the bond is significantly higher compared with knitted webbings with the same seam pattern. The higher seam strength results from the stitch formation in woven, knitted and crocheted bands. In the intersection point or. Connecting portion of the straps and tapes arranged hooks or other elements can therefore be kept safe with less material use.

The at least one active device and / or the grippers of the feed device can also be moved transversely to the machining direction and / or in processing direction. In addition, the grippers of the feeder can be rotated relative to the Bearbeitungsriehtung, for example, to bring obliquely introduced straps in the work area of min least one effecting device.

About the detection device, the structure of the belt can be detected belt and controlled in accordance with the detected structure of the active process. If the belt has weft gaps, the knitting process can be carried out more easily in these sections than in sections which have no such wetting gaps. If a forking of webbings without wiping gaps with the knitted ribbons done so the speed of action can be adjusted.

The above object is also achieved by a technical cal network, which is prepared according to one of the above-described methods be written, wherein the technical network webbing sections and knitted tape sections and has the Gurtbandabschnitte and / or the Wirkbandabschnitte Kar have bonfäden, electrically conductive threads, dyed and / or be coated threads.

In addition, at least one electronic and / or electromechanical unit may be connected to at least one thread of the webbing and / or the effect tape. For example, lighting devices such as LEDs can be connected to electrically conductive threads, so that the technical network can be illuminated with a low electrical power. Furthermore, strain gauges can be introduced into the corresponding sections of the technical network. This makes it possible to record a load on the technical net. The strain gauges of the technical network may be coupled to a device which, upon reaching a maximum allowable load, transmits a message to a computing unit.

Detailed description of exemplary embodiments

Fig. FIG. 1 shows a schematic representation of a system 10 for the production of technical nets 90 with a belt-making unit 12 and a knitting machine 20.

The tape making unit 12 has a tape loom 14 and a memory 16. Over the ribbon loom 14, an endless webbing 92 is produced. Instead of a woven belt 92 and knitted or crocheted Gurtbän can be generated. The production of the straps 92 takes place online, d. H . the straps 92 are prepared before further processing in the knitting machine 20 and fed directly to this. In the memory 16, the webbing 92 is stored over a certain length. The memory 16 serves as a buffer between the ribbon loom 14 and the knitting machine 20. The webbing 92 is manufactured as an endless webbing and fed via an interface of the knitting machine 20. The band production unit 12 is formed as a textile device for the manufacture position of the straps 92 and has for the Weil each differently designed belt straps 92 a corresponding with needles. These needles are supplied with the required threads via thread rollers. In Bandher positioning unit 12 different straps can be Herge provides.

The diversity of the Gutbänder 92 refers both to their binding as well as the number and type of threads used. It is therefore possible to introduce an additional thread in the manufacture online only in a certain area of the belt bands 92. In addition, the straps 92 may have a mutually different width. For this purpose, the webbing 92 may have a transition portion which is cut out by a separator 24 and a Ent sorgungs Sta tion is supplied.

The knitting machine 20 has a processing area in which the Gurtbandzuführeinheit 22, the webbing 92 is introduced. The Gurtbandzuführeinheit 22 preferably has a gripper, which in the direction of arrow 112, orthogonal to the processing direction processing 110, a webbing 92 fetches from the memory 16 and stores in the processing area. For this purpose, a plurality of grippers may be provided, which also make the position of the belt bands 92 with respect to the alignment to the processing direction 110. A detection device with at least one camera monitors the insertion and the position of the webbing 92. After aligning the webbing 92, it follows via the severing device 24 a separation of the webbing 92 to provide a webbing section which is further processed at closing. For this purpose, a laser cut or a hot cut done. The described methods also allow a seal of the cut end of the webbing 92.

In beispielhaf th embodiments as Ladungssicherungsnet z, the networks can be a width of eg. 2.4 m. The length of the technical network 90 does not depend on the width of the processing area, but is determined by the length of the impact belts 94 fabricated via the device 46.

Fig. FIG. 2 shows a further schematic representation of a plant 10 for the production of technical nets 90 with a ribbon production unit 12 and a knitting machine 20. In FIG. 2 additional gripping units 32 of a feeder 26 are shown. The feeder 26 serves to supply the webbing section 42 into the working area of the working devices 46. For this purpose, the individual gripping units 32 have grippers 30 which hold the webbing 92. The gripping units 32 as well as the active devices 46 can be displaced orthogonally to the machining direction 110 in the direction of the arrow 112. It is possible to determine the distances between see two bands 94 to change. The distances between two belt straps 92 can be regulated via the feed speed of the goods belts 92 and the speed of action via the active devices 46.

The entire system 10 is therefore in an online process, a technical network 90 in confectioning ter size starting from Threads. The finished technical network 90 then has a corresponding color and Coating as well as desired size. Can then optionally hooks or other elements to the connecting portions 96 or the ends of the straps 92 and. Wirkbän 94 are attached.

Fig. 6 shows a schematic representation of a Zuführein device 26 with a beam 28 and holders 31 which are attached via a bracket 29 to a beam 28. The hold-down device 31 press a webbing 92 against a work table 21 and guide the webbing 92 to the active devices 46 to. The active devices 46 are shown schematically and have a plurality of bars with hole needles and slider needles. In addition, the active devices 46 comprise the additional base bar 44 for feeding the weft thread over the knit strip width of the knit tapes 94.

The bracket 29 with the hold-down 31 can be displaced both in the direction of the arrow 114 and in the direction of the arrow 116. The displacement in the direction of the arrow 116 is via a method of the beam 28, which guides the webbing 92 by the displacement in the working area of the active devices.

Fig. FIG. 7 shows a schematic illustration of an alternative feed device 26 with a gripping unit 32, as already provided for the system 10 of FIG. 2 has been described. The gripping units 32 have at their lower end on the grippers 30, which are also movable in the direction of the arrow 116 and in the direction of the arrow 114. About the gripper 30 can be used for example a webbing 92 and a substance underneath 100 grasped and a work area of the devices 46 Wirkeinrich be supplied. The work table 21 can accordingly be designed so that the gripper 30 causes the holding webbing 92 can be fed without deforming it to the active device 46.

Fig. 8 shows a schematic representation of the gear mechanism 34 of a knitting machine 20. The driven disc 36 additionally has an opening 38. Within this opening 38, a first end of the propeller shaft 40 is aufgenom men. This end can be moved within the opening 38 via a servo motor or other means in the direction of the arrow 118, so that the movement of the Schlit least 42 and thus the additional base bar 44 varies in the direction of the arrow 120. Accordingly, the width over which the weft thread is passed through the base bar 44 changes. This can be the width of the impact bands 94 change. For example, the impact tapes 94 may assume here by convex or concave shapes.

Due to the short transmission path of the rotational movement in the direction of arrow 112 in the linear movement in the direction of arrow 120 via the propeller shaft 40 very high rotational speeds can be achieved. This makes it possible to perform the knitting process faster.

Fig. 9 shows a schematic representation of a technical network and active devices 46 of a knitting machine 20.

The formation of the various embodiments of the equipment 10 shown in the figures also make it possible to provide technical nets 90 with straps 92 and knit bands 94 which are substantially skewed and have no orthogonal arrangement with respect to each other. Fig. 9 shows a clutch of intersecting straps 92 which are brought over the Gurtbandzuführeinheit 22 in the processing area of a knitting machine 20. The orientation of the straps 92 will hold Beibe on the feeders 26, wherein the feeder 26, the straps 92 in the desired orientation of the working area of the active devices 46 supplies. For several intersecting straps 92, the feeder 26 may have a plurality of independently voneinan controllable gripper 30. In addition, 26 may be provided in addition to a first feeder 26 at least one second Zuführein device. The intersecting straps 92 are additionally meshed with the knit band 94 in the sections. In these connecting portions 96, the knitting bands 94 are meshed with two straps 92. The fed th belts 92 can be supplied either as continuous woven, knitted or crocheted straps 92. However, if they have a different bond in their connecting regions, then the formation of these binding segments must follow the oblique arrangement of the straps 92. For such a change in the bond in these connecting portions, a diagonally set jacquard weave may be incorporated. Advantageously, for the second webbing 92, which intersects a first webbing 92, the bond is introduced into the web, so that a substantially congruent overlap occurs in the joining region of the webbings 92. Subsequently, the intersecting straps 92 are meshed with the bands 94.

Fig. 10 shows a schematic representation of a technical network with straps 92 and ribbons 94, which are meshed in connec tion sections 96 with each other. In Fig. 10, the weft thread 98 is shown, across the width of the Impact bands 94 is guided and the ribbons 94 gives additional stability and the width of the impact bands 94 pretends.

An advantage of a so-called weave weave is that, compared to a knitted connection of knitted webbings with a knit tape, a significantly higher seam strength is achieved with the same seam patterns. The connecting portions 96 are therefore more resilient than Verbindungsbe rich in purely knitted connection points.

At the joints 96 fasteners such as hooks can be attached. In addition, electrically conductive threads can be introduced into the straps 92 and / or knit bands 94. These allow both a power supply to the power supply as well as a determination of a load of the technical network 90, since it comes due to deformation to changes in the resistance of the electrically conductive threads.

The systems 10 described herein enable on-line repositioning of engineering nets 90 from threads to a finished finished technical network 90.

In a system 10, detection devices may additionally be provided with at least one camera and sensor devices. The introduced belt straps 10 can be picked up by cameras and the recorded pattern compared with example patterns stored in a memory. If the patterns of the recorded webbing 92 deviate from a specification, such as defects, this section can be separated via the separating device 24 and a disposal device of the knitting machine 20 or. the system 10 are supplied. The Gurtbandzuführeinheit 22 then accesses the tape making unit 12 and takes a free end of the endless belt 92 and brings this in the processing area of the knitting machine 20. Only after the detection belt means 92 posi tively matched with a pattern or gene detected by Sensoreinrichtun as error-free was, the webbing 92 can be supplied to the work area of the active devices 46 via the Zuführein devices 26.

If an inserted webbing 92 has a weft gap or otherwise formed connecting section, this can also be detected by a camera. The camera then controls the belt feeder 22 with corre sponding gripping elements so that the webbing 92 accordingly the orientation of the active devices 46 dashebet or causes alignment of the active devices 46 and the gripper 30 in accordance with the acquired data.

In other forms of execution is pre-give a control on how a technical network 90 to be manufactured should be designed. Accordingly, the active devices 64 can be pre-positioned. The supplied and required Gurtbandabschnitte are then made on the endless webbing 92 online in the tape manufacturing unit 12. The education from the width of the webbing 92 may vary as well as the binding of the webbing 92. In addition, the webbing 92 with respect to the formation of the distances of the technical net's 90 also have convex or concave areas. For this purpose, a Schussfa is performed according to the width of the webbing 92 in the tape making unit 12 analogous to the knitting tape 94. LIST OF REFERENCE NUMBERS
