Description

It describes a plant for the production of a technical network, a process for the production of a technical network and a technical network. Technical networks can be used for various purposes. Technical networks can be used for example as load securing nets or as sports networks. Instead of a load securing, for example in commercial vehicles, in technical networks, objects or elements can be held together.

The technical networks described herein are not limited to the fields of application exemplified above. The technical networks have a high load capacity in both the longitudinal and in the transverse direction through their training. The technical networks are designed in particular as seamless networks and have no connecting seams in the connection region between two intersecting band sections.

State of the art

Seamless networks are known from the prior art, wherein at an angle to each other extending bands are intermeshed or forfeited at the intersection points. Such nets have a much greater resilience compared to nets with sewn tapes.

• - The knitting machine has at least one effecting device for forking a yarn sheet with a webbing portion of the supplied webbing for the production of a technical network with intersecting webbings and ribbons.

The system enables online production of technical networks. For this purpose, the webbing is made in accordance with the technical network to be produced on the tape making unit. The system may also include a plurality of tape manufacturing units that provide mutually differently configured webbings.

The band-making unit can be designed, for example, as a ribbon loom and has corresponding tools for weaving the webbing. About thread reels of weaving the respective required threads are supplied.

If it is provided that the technical network has webbings with different widths, then the band-production unit can change the width of the webbing as needed. In addition, the band-making unit can introduce different threads into the webbing. The selection of the threads takes place depending on the webbing to be produced.

In further embodiments, in addition to or as an alternative to a ribbon loom, the tape making unit has tools provided to provide a knitted or knitted webbing. Furthermore, a Häkelgalonband can be produced as webbing via a corresponding device.

Preferably, however, woven, knitted or crocheted galloon ribbons are provided via the band-making unit, since these form a better bond in the subsequent knitting process. Since, for example, a woven belt webbing has a more complex stitch formation, a better connection is achieved via the meshed knit warp threads in the connection area of the technical net.

In the band-making unit webbings can be provided both with and without a wiping gap. In addition, the binding structure may change within a band.

In further embodiments, the straps may be designed both with and without an effective edge. This applies both to belts with modified binding and straps without changes in the binding.

If a belt strap has wiper gaps, the weft threads in the wiper gap can be guided over the wiper gap at least once or twice with a change in binding. Preferably, a change in binding of weft threads within the weft gap takes place in accordance with the width of the weft gap.

About the Gurtbandzuführeinheit the webbing is fed to a processing area of the knitting machine. For this purpose, the Gurtbandzuführeinheit may have grippers which grip the webbing of the wall-making unit and angled, z. B. orthogonal, move to the machining direction in the knitting machine. The webbing is fed to a processing area.

In further embodiments, the webbing may also be introduced at a different angle to the processing direction of the knitting machine.

From the processing area, the webbing is fed to the work site of the at least one active device. The active device generates a knit tape in the machine direction, which is intermeshed at intersection points with a webbing section via the active device with this.

In further embodiments, the tape manufacturing unit has a memory in which produced straps are stored, wherein the Gurtbandzuführeinheit accesses the memory. The storage is designed to provide a lead for processing the webbings. The online process of manufacturing the straps is not limited thereby. The memory serves as a supply unit between an example formed as a ribbon loom manufacturing unit and a transfer station of the knitting machine. The memory can also serve as a buffer for the endlessly produced webbing, wherein each webbing sections are further processed. A control regulates the production of the webbings in the band production unit and the knit bands via the at least one active device. It thus takes place a coordinated production. In particular, via the tape production unit, a production adapted to the need for a network is produced, whereby errors due to incorrectly introduced bands are ruled out.

The at least one active device can be movable transversely to the machining direction and / or in the machining direction. As a result, technical networks with different widths and openings as well as different network geometries can be realized.

The knitting machine may further comprise a separating device for cutting the supplied webbing. The cutting can be done by means of ultrasound or a hot cutter. This is also a seal of Gurtbandenden.

In addition, the installation can have a coating unit downstream of the knitting machine in the machine direction for coating and / or dyeing the technical net. From the coating unit, the technical network is dyed and / or provided with a coating which, for example, improves the mechanical properties of the technical network. A coating can also provide flame retardancy, heat protection or cut protection. In particular, a corresponding coating can be provided with regard to aggressive media that come into contact with the technical network in use. The coating can also be provided with pigments in order to simultaneously provide a coloring of the technical network. A coating can also provide protection provide against several different stresses.

In addition, the installation can have a finishing unit downstream of the knitting machine in the machining direction for the lengthwise and widthwise provision of nets. The assembly unit can also have separating devices which separates the manufactured technical network into correspondingly large subnetworks. The assembly unit makes it possible to manufacture the technical network according to customer requirements, especially as piece goods or tapes or by the meter. In addition, a border assembly is possible, wherein a finished technical network is provided by means of a mechanical separation section or via ultrasound. The provision of technical networks can be carried out either as piece or roll goods. If the installation also has a coating unit downstream of the processing direction, then the finishing unit is located downstream in the processing direction of the coating unit.

In other embodiments, the installation can have a device upstream of the knitting machine in the machining direction for the provision of laminates. Such sheet-like substances can be, for example, fine-meshed nets, nonwovens or textile webs. These textile webs are then fed together with the webbing of the at least one active device, which connects the knit tape both in connection areas with the webbing as well as over the entire length of the active tape and width with the supplied material. At the point of intersection with the webbing, there is also a continuous connection of the knit band to the webbing and the fabric underneath and / or above it. Not only can a fabric be supplied through the device, but it is also possible to provide both a fabric below the webbing and a fabric over the webbing.

The system may further comprise a detection device with at least one camera, which is provided for detecting the position and the configuration of the webbing. The detection device is used for positionally accurate alignment of the webbing during insertion into the processing area and into the workstation of the active device. The detection device communicates with a control unit for the system and knitting machine, which controls the Gurtbandzuführeinheit accordingly. The orientation of the webbing is therefore determined via the detection device and can be corrected via the units coupled thereto.

In further embodiments, the at least one active device can be arranged and controlled in accordance with the information obtained via the detection device. For example, the webbing may have connecting portions for the knit tape which are formed as a weft-gap portion or as a coarse-meshed portion. About the detection device, the position of these sections is determined 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 tape manufacturing unit. The tape making unit can use this information to adjust the manufacture of the webbing.

The system may further comprise a transmission device which is coupled via a propeller shaft with a carriage, wherein the carriage is mounted transversely movable to the machining direction and connected to a weft insertion of the at least one active device for a partial shot over the effective bandwidth. The weft also serves to adjust the width of the effect tape. Thus, for example, the weft thread, the knit tape having convex or concave portions. The weft also serves to give the knitted tape stability. For this purpose, the weft thread is guided over the width of the knit tape, whereby a linear movement is required. The weft thread insertion device can have an additional base bar which can be moved transversely to the machining direction and deposits or inserts a weft thread over the effective strip width. For a transmission of this movement, the gear 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 rotational movements 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 is counteracted. In addition, the propeller shaft can be made more stable, since this has only a small length. If the knitting machine has a plurality of knitting devices, the additional basic bars of each knitting device are linearly coupled to the sled. The additional basic bars can be coupled to each other.

In further embodiments, the rotatable unit of the transmission device may comprise a groove or guide, in which a receiving portion for one end of the propeller shaft is received displaceably. This can be the width of the supplied weft set. For example, in a change in the position of this end of the propeller shaft during the production of the active bands, the width of the active band can be changed. 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 the additional base bar as a function of the effective speed.

In further embodiments, the Gurtbahnzuführeinheit may be configured to supply the webbing at an angle between 10 ° and 170 ° relative to the processing direction of the knitting machine. For this purpose, the webbing feed unit can have gripping elements which can be displaced in the feed direction as well as gripping elements arranged rotatably relative to the feed direction. The feed unit may be configured such that first the webbing is brought into the processing area. Subsequently, via the Gurtbandzuführeinheit the orientation of the webbing relative to the machining direction.

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 machining direction depending on the orientation of the straps. Therefore, the at least one active device is arranged downstream of the processing area in the machining direction.

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

Analogous to the detection device, the sensor device can detect errors in the webbing. If a fault is detected, the webbing is cut to length and the part of the webbing with the defect is fed to a disposal station via the webbing feed unit. Subsequently, the webbing feed unit takes a new portion of the webbing from the tape making unit and inserts it into the processing area.

Instead of defects in the supplied webbing, the supplied webbing may also have marking elements. Such marking elements may be metals, for example, which can be detected by a sensor device. The marking elements give feedback on the section of the webbing. Such marking elements can also be incorporated in the tape manufacturing unit. For this example, punching elements can be provided. 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. These components can later be used to arrange further components or to check the webbing or a technical network.

The knitting machine can have a feed device which has a beam and brackets with hold-downs arranged on the beam. About the hold the webbing is held on a work table and placed in the work area of at least one active device.

In further embodiments, the knitting machine can have a feed device with grippers, wherein the webbing and / or a flat fabric can be fed to the workstation of the at least one active device via the feed device. The grippers can be moved both in the machine direction and transversely to the machine direction. In further embodiments, the feed device and / or individual grippers of the feed device are rotatable relative to the machining direction, so that a direction which is different from an orthogonal orientation of the webbing in the machine direction is made possible. Even after the alignment of the webbing at an angle ≥ 90 ° relative to the processing direction on the Gurtbandzuführeinheit the grippers of the feeder can hold the webbing in this position and feed the at least one active device. In addition, the grippers can not only supply the webbing to the working area of the at least one acting device, but also hold at least one fabric and feed it to the work area. In further embodiments, the supply means may comprise grippers for the at least one fabric as well as grippers for the webbing, the orientation of the fabric being different from the orientation of the webbing.

The mobility of the gripping elements relative and transverse to the machining direction makes it possible to change the distance between the grippers to each other. This improves the provision of different mesh geometries with different tape apertures since the grippers can always hold the webbing at the edge of a workspace. The grippers also follow the position of the at least one active device. Preferably, the grippers and the active device control technology coupled together.

The above object is also achieved by a method for producing a technical network using a plant according to the embodiments described above, wherein in the band-making unit, a webbing is produced, which is fed to the knitting machine via the Gurtbandzuführeinheit, and wherein the knitting machine supplied webbing is forfeited via the at least one active device in a connecting region with yarn sheets.

The webbing can be fed at an angle between 10 ° and 170 ° relative to the machine direction of the knitting machine. This allows the provision of technical networks, wherein the orientation and shape of the openings in the technical network can be diamond-shaped.

The tape making unit allows for the provision of various webbing straps that can vary in both binding and width. In addition, for example, electrically conductive threads can be incorporated, which allow a subsequent contact with electrical elements. Furthermore, already dyed threads can be fed to the tape making unit. It is also possible to additionally supply a plurality of colored threads and / or bands and a plurality of differently colored threads and / or bands, both in the 0 ° and in the 90 ° direction. The feed here refers to the production and thus production direction 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 threads of the band manufacturing unit.

The partial shot for the knitted tape produced by the at least one active device can be made in accordance with the design of the webbing. The technical network may have both varying distances of the individual belt and impact belts to each other 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 coloring by the coating unit and / or packaging by the assembly unit can be done offline or online. In a preferred embodiment, the processing of the technical network was done online. This makes it possible to provide a technical network from threads supplied to the respective components to a ready-made technical network. For this purpose, the system may have a winding device, which winds up the pre-fabricated technical network after assembly and makes available for further transport to the customer. In alternative embodiments, the technical network can also be merged after assembly. Merging is suitable for networks of different sizes.

The technical network can then be provided with other elements, such as hooks. By the preferred use of non-knit webbings, i. H. Web, crochet or knit ribbons, the bond is significantly higher compared to knitted webbings with the same seam pattern. The higher seam strength results from the stitching of woven, knitted and crocheted tapes. Hooks or other elements arranged in the crossing point or connecting section of the straps and impact straps can therefore be held securely with less use of material.

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 the machining direction. In addition, the grippers of the feeder can be rotated relative to the machining direction, for example, to bring obliquely introduced straps in the working area of at least one active device.

About the detection device, the structure of the webbing can be detected 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 network, which is manufactured according to one of the methods described above, wherein the technical network Gurtbandabschnitte and Wirkbandabschnitte and the Gurtbandabschnitte and / or the Wirkbandabschnitte carbon threads, electrically conductive threads, colored and / or coated threads respectively.

In addition, at least one electronic and / or electromechanical unit with at least one thread of the webbing and / or the Wirkbands be connected. 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 allows the detection of a load of the technical network. The strain gauges of the technical network can be coupled to a device which, upon reaching a maximum permissible load, transmits a message to a computing unit.

The orientation of the straps 92 is via the feeders 26 maintained, with the feeder 26 the straps 92 in the desired orientation to the work area of the effectors 46 supplies. For several intersecting webbings 92 can the feeder 26 several independently controllable grippers 30 respectively. In addition, in addition to a first feeder 26 at least one second feeding device 26 be provided. The crossing straps 92 be in the sections in addition to the knit tape 94 meshed. In these connection sections 96 are the effective bands 94 with both straps 92 meshed. The supplied webbings 92 Can be either as continuous woven, knitted or crocheted straps 92 be supplied. However, if these have a different bond in their connecting regions, the formation of these binding sections must be the oblique arrangement of the straps 92 consequences. 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 is a first webbing 92 crossed, the bond introduced mirrored, so in the connection area of the straps 92 a substantially congruent overlay occurs. Then the intersecting straps 92 with the bands 94 meshed.

An advantage of a so-called Web-Wirkbindung is that compared to a knitted connection of knitted webbing with a knit tape a significantly higher seam strength is achieved at the same seam images. The connecting sections 96 are therefore more resilient than connecting areas in purely knitted connection points.

To the connection points 96 fasteners such as hooks can be attached. In addition, electrically conductive threads in the straps 92 and / or impact tapes 94 be introduced. These allow both a power supply to the power supply as well as a determination of a load on the technical network 90 because deformation results in changes in the resistance of the electrically conductive filaments.

The systems described herein 10 enable online production of technical networks 90 from threads to a ready made technical net 90 ,

At a plant 10 In addition, detection devices may be provided with at least one camera and sensor devices. About cameras, the straps introduced 10 recorded and the recorded pattern are compared with stored in a memory sample patterns. Assign the patterns of the recorded webbing 92 Deviations from a specification, such as defects on, so this section on the separator 24 separated and a disposal facility of the knitting machine 20 or the plant 10 be supplied. The webbing feed unit 22 then access the tape making unit 12 back and take a free end of the endless webbing 92 and brings this into the processing area of the knitting machine 20 , Only after the webbing on the detection device 92 positively matched with a pattern or was detected by sensor devices as faultless, the webbing 92 the workspace of the impactors 46 via the feeders 26 be supplied.

Indicates an inserted webbing 92 a weft gap or otherwise formed connecting portion, so this can also be detected by a camera. The camera then controls the Gurtzuführeinrichtung 22 with appropriate gripping elements on so that the webbing 92 according to the orientation of the active devices 46 is aligned or causes an alignment of the active devices 46 and the gripper 30 according to the data collected. In further embodiments, a control is provided, such as a technical network to be manufactured 90 should be trained. Accordingly, the effectors can 64 be positioned in advance. The supplied and required Gurtbandabschnitte are then on the endless webbing 92 online in the tape manufacturing unit 12 manufactured. The formation of the width of the webbing 92 It can as well as the binding of the webbing 92 vary. In addition, the webbing can 92 with regard to the formation of the distances of the technical network 90 also have convex or concave areas. This is analogous to the knitted tape 94 a weft according to the width of the webbing 92 in the tape making unit 12 guided.
