Description

 METHOD FOR PRODUCING A FLEXIBLE SURFACE IMAGE

 AND FLEXIBLE SURFACE IMAGES

The invention relates to a method for producing a flexible Flächenge- image, with electrically conductive structures and a flexible sheet.

Such surface elements are commonly used to provide protection against burglary, theft or vandalism. In general, electrically conductive structures in the flexible fabric form the safety structures with which protection against unauthorized interference is achieved.

From DE 10 2015 103 533.2 a method for the production of safety structures in a surface element is known. By means of a Kettenwirkma machine or Raschel machine safety threads forming threads are incorporated into the surface element, which at the same time form cut-resistant structures and sensor structures.

The security structures are designed such that the functionality thus achieved as a cut-resistant structure ge an effective mechanical protection causes puncture of the surface element with objects such as knives or similar sharp-edged objects. The cut-resistant structures are designed so that at most only a local piercing into the surface element is possible, but not a large-scale separation of the surface element.

At the same time, with the function of the security structures as sensor structures, a further security function is achieved in such a way that puncturing is detected sensory, so that, for example, an alarm signal is then generated, which signals unauthorized intervention on the surface element. In this case, the security structures formed by the threads form a continuous sensor structure extending over the entire surface of the planar element such that an interruption of a thread of the security structure caused by external influences changes an electrical parameter which is detected by a measuring device.

The production of these continuous security structures takes place in the production process of the surface element with the warp knitting machine or Raschel machine. This requires a high degree of precision and thus correspondingly high demands on the production process and thus also on the machines for producing the surface element.

The invention has for its object to provide a flexible sheet of the initially mentioned type, which on the one hand have high functionality and on the other hand can be efficiently produced.

The invention has for its object to provide a method by means of which fabrics with high, reliable protection function can be produced at the same time low weight.

To solve this problem, the features of the independent claims are provided. Advantageous embodiments and expedient Weiterbildun conditions are described in the dependent claims. The invention relates to a method for producing a flexible Flächenge image with electrically conductive structure. The method comprises the following process steps:

Providing a flexible sheet having an array of discrete electrically conductive features;

- Producing at least one electrically conductive connection between at least two discrete electrically conductive structural elements. The connection generates an electrically conductive connection that extends at least in sections.

Furthermore, the invention relates to a corresponding flexible sheet.

An important field of application of the flexible sheet produced by the method according to the invention is the wrapping of articles such as goods to be transported, suitcases, bags and the like. In particular, the flexible sheet can form a tarpaulin. The electrically conductive structures thereby form security structures which prevent unauthorized access to the items packed with the envelope. The security structures can, in particular, form sensor structures with which a local damage, in particular a puncture of the wrapper, can be detected so that an alarm message can be generated in such a manipulative intervention.

In the event that the electrically conductive structures have a sufficiently high mechanical stability, the safety structure formed with the electrically conductive structures can also assume the function of a sectional solid structure, that is to say a mechanical protection against a penetration of the flexible fabric with pointed objects as done with knives and the like. A prerequisite for such a protective function is that the electrically conductive structure and thus the security structure structure extends as closely as possible over the entire surface of the flexible sheet. In particular, for the formation of the electrically conductive structure as a sensor structure, it is furthermore essential that continuous electrically conductive structures are present in the flexible area structure, so that the electrically conductive structures form sensor elements which have the largest possible partial area or preferably a continuous structure the entire surface of the flexible sheet training, so that a complete, full-surface monitoring of the flexible WING chengebildes is made possible.

According to the invention, the flexible sheet is produced in a two-stage process. In a first method step, the flexible sheet is produced with the discrete electrically conductive structural elements, wherein the flexible sheet, unlike the discrete electrically conductive structure, consists of an electrically non-conductive material. In a subsequent procedural step, electrically conductive structures are formed between defined discrete electrically conductive connections, so that continuous electrically conductive structures are thereby produced at least in sections. These then form the security structure.

A significant advantage of the method according to the invention is that a high-precision and reproducible production of continuous electrically conductive structures is made possible. If the electrically conductive structures are used as sensor structures, it is advantageous that exactly reproducible sensor properties can be realized with the electrically conductive structures produced in this way.

This applies in particular when the flexible fabric is a textile fabric.

In this case, the discrete electrically conductive structural elements are formed by electrically conductive threads.

The flexible fabric may generally be a woven, knitted, knitted or non-woven fabric. In principle, the flexible sheet may also be a film or a paper, wherein even then discrete electrically conductive structural elements in the form of Fä can be incorporated into the flexible sheet.

The introduction of threads to form the discrete electrically conductive structural elements generally takes place mechanically, in particular with textile machines such as raschel machines or warp knitting machines.

An essential aspect of the invention is that the discrete electrically conductive structural elements are very easily incorporated into the flexible planar structure, wherein the introduction of the discrete electrically conductive structural elements may well be subject to tolerances, that is, he has not received increased accuracy requirements. In particular, it is also possible for the first method step to be followed by further steps for the treatment of the flexible sheet, such as thermal fixing processes, which lead to warping or shrinking of the flexible sheet and thus to a change in the spacings of the discrete, electrically conductive structural elements. These tolerance-related fluctuations can be easily compensated for by the production of the electrically conductive compounds adapted thereto in the second method step. As a result, continuous electrically conductive structures can be produced accurately and reproducibly. This is not the case in a one-step manufacturing process as known in the art. There continuous electrically conductive structures are produced in a manufacturing process. Although there is a second process step for the separate production of electrically conductive connec tions between discrete electrically conductive structural elements superfluous. However, the production of continuous electrically conductive structures as complex two-dimensional patterns is extremely complicated and requires high accuracy, which makes the manufacturing process more expensive. This is especially true when the continuous electrically conductive structures of threads are ge forms that with suitable textile machines in the flexible sheet be incorporated. These textile machines, such as Kettenwirkma machines or Raschel machines between this must have complex Zusatzein directions to be able to work the continuous electrically conductive structures exactly in the flexible fabric. Another significant advantage of the invention is that by the incorporation of electrically conductive compounds in a separate Ver process step in a simple way an application-specific adaptation of the continuous electrically conductive structures can be realized. For example, by suitable variations of the electrically conductive connection, different circuit methods such as series or parallel circuits can be realized.

In this case, a multiple arrangement of electrically conductive connections can advantageously be formed, as a result of which a plurality of discrete electrically conductive structural elements are combined to form a continuous, electrically conductive structure.

The discrete electrically conductive structural elements thus provide a large-area grid of conductive elements which only have to be interconnected locally at suitable locations by the electrically conductive connection in order to generate the continuous electrically conductive structures. This leads to a rational , easy to monitor production process.

According to an advantageous embodiment of the invention, individual flexible fabrics are assembled from a sheet-like base material, thereby providing at least one flexible sheet with an array of discrete electrically conductive structural elements. In at least one flexible sheet is produced by producing at least ei ner electrically conductive connection an at least partially Runaway existing electrically conductive structure. The base material can be produced over a large area, the manufacturing effort for this purpose is particularly low. In particular, the base material can form a long, auffollbare material web.

Advantageously, prefabricated flexible fabrics with application-specific predetermined dimensions are produced from the sheet-like base material.

The production of individual flexible fabrics can be done by cutting or punching the base material or the like. This makes it possible to fabricate flexible fabrics in different dimensions and geometries very simply, quickly and efficiently. After assembly, in particular the cutting of the base material, the flexible fabric thus produced can be aftertreated, in particular thermo-fixed.

The distortions that occur in this case affect the spacings of the discrete electrically conductive structural elements. However, this is not critical, because only in a subsequent process step, the electrically conductive Verbindun conditions are incorporated to produce continuous electrically conductive structures.

According to an advantageous embodiment of the invention, the sheet-like base material on at least one side closed electrically conductive structures ren. By cutting the flexible sheet discrete electrically conductive structural elements are formed.

Since continuous electrically conductive structures are already present in sections on the base material in advance, only a smaller number of electrically conductive connections have to be incorporated after the fabrication, in particular cutting to the flexible sheet thus produced, to the desired continuous electrically conductive structures To obtain, that is to be incorporated in an electrically conductive Ver connection existing sections of electrically conductive structures are further processed into larger contiguous continuous electrically leitfähi conditions structures. In general, application-specific electrically conductive connections can be made in the prefabricated flexible fabrics.

Thus, only by an application-specific adaptation of the electrically conductive connection different continuous electrically conductive structures, which can be used in particular as sensor structures, are produced.

According to a first variant, the electrically conductive connection is formed by mechanically interconnecting two discrete electrically conductive structural elements by means of an electrically non-conductive connecting element. Preferably, two adjacent discrete electrically conductive structural elements extend in close proximity to one another in the region in which the electrically conductive connection is to be formed. These discrete electrically conductive structural elements, which are in particular formed by threads, can then be guided against one another by suitable tensile forces which are exerted with the connecting element and thus electrically connected.

An example of this is the setting of two electrically conductive Verbindun conditions. For this example, a non-electrically conductive thread can be used, which is machined, in particular with a textile machine, is incorporated into the flexible fabric. According to a second variant, the electrically conductive connection is formed by two discrete means of an electrically conductive contact element electrically conductive structural elements are electrically conductively connected to each other.

For example, the contact element is formed by at least one electrically leitfähi gene thread, which is incorporated in the flexible sheet. This embodiment is particularly suitable when the discrete electrically conductive structural elements themselves are formed from threads, which are then connected to each other by further electrical threads, for which purpose textile machines can be used with which weaving, knitting or knitting processes are performed. Alternatively, the contact element may be applied to a surface of the flexible sheet structure.

The prerequisite for this is that the discrete electrically conductive Strukturele elements are exposed on the surface of the flexible sheet, to which the respective contact elements are applied. For example, the contact element is applied in a stamping process, a printing process Be or Aufsprühprozess on the surface of the flexible WING chengebildes.

The invention will be explained below with reference to the drawings. Show it:

Figure 1 shows schematically a base material 1, which is in the form of a long Rahn. This base material 1 can in principle be formed from a paper or a foil. In the present case, the base material 1 forms a flexible surface, for example a woven, knitted or crocheted fabric or else a fleece. In the consisting of an electrically non-conductive material base material 1 is a multiple arrangement of discrete electrically conductive structure elements 2, 2a, 2b incorporated. In the present case, the discrete electrically conductive structural elements 2, 2a, 2b are formed by threads which are incorporated into the base material 1 during the production process. As can be seen from FIG. 1, the discrete electrically conductive structural elements 2, 2 a, 2 b are sinusoidal, wherein neighboring discrete electrically conductive structural elements 2, 2 a, 2 b do not touch one another, but close to each other in sections, thus forming an open grid-shaped structure. The electrically conductive threads forming the discrete electrically conductive structural elements 2, 2a, 2b preferably consist of a metallic material, in particular stainless steel, a plastic of a rock / basalt fiber and / or a glass fiber. In a confectioning individual flexible fabrics 3 are made of the base material 1 application spezzi fish. The assembly can be done for example by cutting the base material 1.

The flexible sheet 3 shown in Figure 2 is rectangular. Naturally, other geometries of the flexible sheet 3 are possible. In a further separate method step, adjacent discrete electrically conductive structural elements 2a, 2b at the upper and lower edges at locations where they are located at a small distance, connected by electrically conductive connections 4, so that a continuous electrically conductive structure is formed by the conductive connection , In the exemplary embodiment shown in FIG. 2, an arrangement of electrically conductive connections 4 is provided such that a continuous electrically conductive structure is generated which extends over the entire surface of the flexible sheet 3. Such a continuous electrically conductive structure is particularly advantageous as a sensor structure that is suitable for detecting a puncture of the flexible sheet 3. The discrete electrically conductive structural elements 2, 2a, 2b form such a mesh engma narrow that a collision of a sharp object such as a knife with certainty leads to a breaking of the electrically conductive structure, which of the sensor structure and the units connected thereto (hineu - tet with the terminals + and -) is defined safely. The flexible Flächenge 3 may then form in particular a tarp, are covered with the goods to be protected Gü. The embodiment according to FIG. 2 can be modified in such a way that a plurality of continuous electrically conductive structures are formed by the electrically conductive connections 4, which are insulated from one another.

The electrically conductive connections 4 can be designed as electrically non-conductive connection elements which mechanically connect two adjacent discrete electrically conductive structure elements 2a, 2b, so that a conductive connection between the discrete electrically conductive structure elements 2a, 2b is created by this contact.

For example, by means of a suitable textile machine electrically non-conductive filaments can be incorporated by means of which the discrete electrically conductive structural elements 2, 2a, 2b are connected to one another at a punctiform contact point.

Alternatively, the electrically conductive connections 4 can be formed by means of an electrically conductive contact element, two discrete electrically conductive structural elements 2a, 2b are electrically conductively connected to each other ver.

The contact elements may be formed by electrically conductive threads, which are incorporated into the flexible sheet 3 by means of a suitable textile machine. In the event that the discrete electrically conductive structural elements 2a, 2b are exposed on a surface of the flexible sheet 3, contact elements can also be applied to this surface as electrically conductive connections 4.

For example, the contact element is applied to the surface of the flexible sheet 3 in a stamping process, a printing process or a spraying process. FIG. 3 shows a further exemplary embodiment of a flexible sheet 3. The flexible sheet 3 can again be obtained by packaging it from a base material 1. Alternatively, the flexible sheet 3 can also be produced directly in this form. In this case, a plurality of discrete electrically conductive structural elements 2, 2a, 2b extending parallel to each other and extending along a straight line are provided in the flexible fabric 3.

The material properties of the flexible sheet 3 and of the discrete, electrically conductive structural element 2, 2 a, 2 b can be formed analogously to the embodiment of FIGS. 1 and 2.

FIG. 2 shows the flexible sheet 3 after adjacent discrete electrically conductive structural elements 2, 2 a, 2 b have been connected by an electrically conductive connection 4 in a further procedural step. The electrically conductive connections 4 may be formed corresponding to the electrically conductive connections 4 of FIGS.

The electrically conductive connections 4 are placed so that a continuous electrically conductive connection 4 is produced from the discrete electrically conductive structural elements 2, 2 a, 2 b, which extends over the entire surface of the flexible sheet 3. Of course, other configurations of continuous electrically conductive connections 4 are also possible in this case.

Figure 5a shows another embodiment of a base material 1, which is formed in the form of a textile surface.

In this base material 1, first electrically conductive structural elements 5 a and second electrically conductive structural elements 5 b are incorporated in the form of electrically conductive threads in a periodic sequence, which extend over the entire length of the base material 1. The electrically conductive structural elements 5 a, 5 b cross several times, the electrically conductive structural elements 5 a, 5 b being electrically contacted at these crossing points, whereby primary electrically conductive connections 4 a are obtained between the electrically conductive structural elements 5 a, 5 b. However, adjacent pairs of electrically conductive structural elements 5a, 5b are not electrically contacted with each other.

For use in a particular application, the base material 1 is cut into individual flexible fabrics 3. Depending on the field of application, a flexible fabric 3 with different catches Fi, F 2 , F 3 can be produced, as shown schematically in FIG. 5 a.

Figure 5b shows a cut from the base material 1 according to Figure 5a flexible fabric 3. For this purpose, the base material 1 along a cut line at the catches Fi is cut. After an optional thermal fixing process, subsequent electrically conductive connections 4 b are incorporated between adjacent electrically conductive structural elements 5 a, 5 b in the region of the cut line at Fi, whereby adjacent electrically conductive structural elements 5 a and 5 b form a sectionally continuous electrically conductive structure Sensor structure can be used.

Figure 6a shows a base material 1, which represents a development of Grundma- terials 1 according to Figure 5a to the effect that at the right end of the base material 1 adjacent pairs of electrically conductive structural elements 5 a, 5 b by primary electrically conductive compounds 4 a 'electrically conductive ver prevented are.

Also in this case, by cutting the base material 1, various flexible sheets 3 can be produced. In the present case, the base material 1 at Li and L 2 will each be cut along a cutting line, resulting in two flexible planar structures 3, 3 '.

The flexible sheet material 3 '(at L> L 2 ) already has a partially throughgoing electrically conductive structure with the adjacent electrically conductive structural elements 5 a and 5 b connected via the primary electrically conductive connections 4 a', which are used, for example, as a sensor structure can be.

In another flexible fabric 3 (at L <Li) subsequent electrically conductive compounds 4b 'are incorporated, whereby adjacent electrically conductive structural elements 5 a and 5 b connected to each other, so that there is a sectionally continuous electrically conductive structure is generated as the sensor structure can be used.

In this way, from the base material 1, two flexible sheets 3, 3 'can be produced with a continuous electrically conductive structure. Since the cutting lines can be set variably, the sizes of the flexible fabrics 3, 3 'can be adapted to the respective application.
