Description

[0001] Identification plate for equipment

[0002] The invention relates to identification plates for operating equipment which are used to provide operating equipment, such as machines and devices, with a marking within industrial production processes in order to be able to identify them.

[0003] For this reason, high demands are placed on identification plates of this type, resulting in particular from the fact that the marking must ensure permanent attachment and reliable identification of the equipment to be marked, even under adverse environmental conditions. Therefore, the application of a correspondingly permanent marking on the relevant identification plates is essential for industrial use.

[0004] Adverse circumstances include, in particular, those that occur during production and have a damaging effect on a marking. Therefore, the relevant marking plates for equipment are adapted for such use.

[0005] A further requirement for labels of this type is that they must not be flammable or combustible, or only to a limited extent. In manufacturing processes, which also include logistical and testing stages, it is therefore important to prevent the labels from posing a fire hazard if they are exposed to flames, heat, or other influences that could cause or spread a fire.

[0006] Identification plates for equipment of this type are available in various forms. They consist of a marking body, which has a marking carrier for applying a marking and a holding device for securing the marking carrier to the respective equipment.

[0007] The marking can be formed in various ways. For example, it is known to create a marking on the marking carrier by means of laser irradiation, in which the laser radiation causes a contrast or color change on the marking carrier to produce the marking. It is also known to create the marking by printing the marking carrier with a coloring compound, for example, an ink. Various methods for this are known from the prior art.

[0008] For labels of this type, the label body is at least partially made of or consists of a plastic containing a flame retardant to reduce or prevent the label's dangerous fire behavior. Flame retardants are characterized by the fact that they make it difficult for a material to ignite or prevent or at least delay the spread of flame. Such substances are also known as flame retardants.

[0009] State-of-the-art additives are known that are incorporated into plastics to adjust fire behavior to meet requirements when exposed to flame or thermal exposure. Per- and polyfluorinated alkyl compounds, also known by the acronym PFAS, have become established for this purpose. Therefore, the aforementioned alkyl compounds will also be referred to by the acronym PFAS.

[0010] PFAS are characterized, among other things, by their high thermal and chemical stability, which has a beneficial effect on plastics with these properties. However, the problem with these compounds is that they are poorly biodegradable and therefore cause environmental pollution when disposed of. Furthermore, these compounds are considered harmful to health, including being carcinogenic.

[0011] The invention is based on the object of providing an identification plate for equipment with a fire-retardant behavior that at least reduces or prevents at least one of the aforementioned restrictions.

[0012] The invention departs from the idea of ​​providing additional environmental measures to protect a label from flames, thermal, or chemical influences. At the same time, the invention departs from the idea of ​​producing the label with a label carrier made of metal instead of plastic. Furthermore, the invention departs from the approach of providing special disposal means to achieve flame protection.

[0013] The invention solves the problem set for it by developing the identification plate as such in this way.

[0014] To this end, the invention focuses on the design and material properties of the label and offers a solution in that the plastic is designed and constructed in such a way that the plastic is free of a perfluorinated or polyfluorinated alkyl compound and the flame retardant is formed by a polymer structure of the plastic and / or by a PFAS-substituting additive incorporated in the polymer structure of the plastic and / or by an outer layer formed on the label body.

[0015] The invention thus replaces per- and polyfluorinated alkyl compounds with an intrinsic design and configuration of the marking body for flame protection, thus avoiding complex environmental adaptation. To this end, the invention defines a polymer structure of the plastic that is configured and designed in such a way that flame resistance is determined by the design of the polymer structure.

[0016] To achieve an intrinsic flame-retardant effect through the plastic, the invention achieves this instead of or in addition to the polymer structure by incorporating an additive that is at least harmless to health into the PFAS-free plastic. For this purpose, the invention provides a PFAS-substituting additive incorporated into the polymer structure. According to the invention, a PFAS-substituting additive is an additive that, in particular, replaces – at least almost – the fire- or flame-retardant effect of the PFAS in the respective plastic (base material) in an equivalent manner. Accordingly, within the meaning of the invention, the additive is an additive in the base material or plastic that is equivalent to PFAS with regard to the desired or required properties.

[0017] Furthermore, the invention proposes an intrinsic flame-protection effect of the marking body, in which the flame-protection means is formed by an outer layer of the marking body. According to the invention, this outer layer ensures that the marking carrier is temporarily protected from thermal destruction, at least within the required limits, without, or only to a tolerable extent, reducing the marking properties of the marking plate for identifying the equipment.

[0018] For the purposes of the invention, operating resources are means and devices for the industrial production and testing of products. Operating resources include capital goods such as machines, units, and devices, industrial building equipment and their accessories, and, for example and in particular, electrical and electronic installations that are components of production and testing machines or serve their operation. These include, among other things, switching devices, connection stations, and connecting means, such as, for example and in particular, power / signal cables.

[0019] The invention therefore proposes in particular that the plastic is free of a perfluorinated and / or polyfluorinated alkyl compound and that the flame retardant is formed by a polymer structure of the plastic and / or by a PFAS-substituting additive incorporated in the polymer structure, and / or by an outer layer formed on the marking body.

[0020] An advantageous development of the invention provides that the plastic and / or the polymer structure of the plastic is configured and designed in such a way that heating above the melting temperature of the plastic causes flame-free melting of the plastic. This has the advantage that the measures required to achieve adequate flame protection are minimized, such that the desired properties for marking the equipment do not have to be adapted by additional devices, but rather the flame protection is realized intrinsically by the plastic. The invention thus realizes effective flame protection with minimal effort.

[0021] A marking plate formed in accordance with the invention in this way ensures that even if the shape of the marking plate is destroyed or dissolved under the influence of flames or thermal influences, the outbreak or further spread of a fire is prevented. This ensures that a marking plate according to the invention does not constitute a source of danger for fires or the spread of fire.

[0022] The invention therefore proposes in particular that the plastic and / or the polymer structure is designed and constructed in such a way that heating above the melting temperature of the plastic causes flame-free melting of the plastic.

[0023] A fire hazard is particularly present when the shape of a marker sign breaks apart and pieces separate. These fragments can contribute to the spread of a fire.

[0024] To prevent this, a further advantageous development provides that the material combination and / or the polymer structure is designed in such a way that flame-free droplet formation of the plastic is achieved as a result of thermal exposure at or above the melting temperature, which causes the destruction of the identification plate and droplet-forming melting of the plastic. This eliminates the need for further precautionary measures, such as shielding elements or reinforcements of structures surrounding the identification plate. Furthermore, this ensures that even under extreme conditions, the formation of open flames and the spread of a fire are effectively prevented by means of an identification plate according to the invention.

[0025] The invention therefore provides in particular that the material combination and / or the polymer structure is designed in such a way that flame-free drop formation of the plastic is realized as a result of thermal action at or above the melting temperature, which causes destruction of the identification plate and drop-forming melting of the plastic.

[0026] A further advantageous development of the invention relates to the additive for forming a flame retardant. According to the invention, a flame retardant effect can be achieved by the additive itself and / or in conjunction with other components and additives. The additive can therefore be incorporated into the plastic in a soluble form or as an insoluble filler. Soluble incorporation of an additive contributes to the additive being distributed, preferably homogeneously, throughout the plastic. However, this requires that the composition of the plastic permit this.

[0027] In a further advantageous development of the invention, it is therefore provided that the additive is a filler or at least comprises a filler.

[0028] This has the advantage of simplifying the introduction of such an additive into the plastic. Furthermore, it makes it possible to distribute the additive in a targeted and concentrated manner at various locations within the plastic, for example, to create different zones with corresponding material properties. Furthermore, it makes it possible to optimize the material properties of the plastic for a label according to the invention, in line with the requirements.

[0029] The additive may be an organic substance, such as, for example, and in particular, antimony or antimony trioxide, which, when mixed into the plastic of a label according to the invention, provides a flame-retardant effect.

[0030] Irrespective of this, within the scope of the invention the plastic can be an organic or inorganic plastic.

[0031] Accordingly, according to the invention, it is possible to produce a flame retardant using aluminum at low cost.

[0032] Within the scope of the invention, it has also been shown to be advantageous for the additive to be an inorganic substance or to contain an inorganic substance. This makes it possible to adapt the flame retardant to the other components of the plastic in a wide range of ways and to utilize interactions between the components accordingly.

[0033] Inorganic substances can increase the melting point of a label according to the invention and have the advantage of not producing carbon dioxide. Furthermore, they can be produced cost-effectively and are therefore suitable for use.

[0034] Within the scope of the invention, a substance is, in particular, a chemical substance that can be formed from an element, a compound, or a mixture. Thus, a substance can be formed from or consist of one molecule or several molecules, a molecular chain, an element, or an ionic compound. Any combination of the aforementioned forms is also encompassed within the scope of the invention. Within the scope of the invention, it has proven advantageous for the additive to comprise or be formed from a phosphorus substance and / or a nitrogen substance and / or a bromine substance, so that this is taken into account in an advantageous development of the invention.

[0035] A phosphorus substance in the context of the invention contains at least phosphorus. For example, and in particular, so-called black phosphorus has proven to be flame-retardant, inert, and non-toxic, so that a label according to the invention using such a substance benefits from these properties.

[0036] The invention thus enables the formation or use of an organophosphorus or organic phosphorus-based flame retardant in a label according to the invention, which may additionally comprise other substances.

[0037] Organophosphorus flame retardants according to the invention consist of or comprise, for example and in particular, tris(chloropropyl) phosphate, halogen-free organophosphates, such as, for example and in particular, triphenyl cresyl phosphate. In a plastic, these can be added individually or in any combination, for example and in particular, to so-called plasticizers.

[0038] In the context of the invention, a nitrogen substance contains at least nitrogen. Nitrogen is non-flammable, so a label according to the invention can be designed with the effect of nitrogen.

[0039] Within the scope of the invention, the flame retardant can, for example, and in particular, be designed as or comprise a halogen-organic flame retardant, whereby, for example, a bromine-containing flame retardant has proven particularly cost-effective and advantageous. Halogen-organic flame retardants, in particular, exhibit high chemical stability, which allows for correspondingly pronounced flame protection.

[0040] Therefore, within the scope of the invention, a bromine substance is a substance formed by or using bromine. A label according to the invention comprises, for example and in particular, a brominated flame retardant, which allows it to be designed to be flame-resistant.

[0041] Thus, according to the invention, a brominated flame retardant is, for example, and in particular, composed of or formed from a polybrominated diphenyl ether. In addition to hexabromocyclododecane, tetrabromobisphenol A and polybrominated biphenyls have also proven suitable as optional substances within the scope of the invention. Polymer structure of the flame retardant

[0042] In a further advantageous development of an identification plate according to the invention, it is provided that the plastic is formed from at least one of the following polymers or comprises such a copolymer:

[0043] Polyetheretherketone [ abbreviated PEEK],

[0044] Polyethylene [abbreviated PE], in particular high molecular weight polyethylene [abbreviated PE-UHMW], high temperature resistant plastic, in particular polyphenylene sulfide [abbreviated PPS], synthetic polymer, in particular silicones, polycarbonate, polyamide, polyketones,

[0045] - polybutylene terephthalate,

[0046] Polymer blends, such as and in particular polycarbonate with acrylonitrile-butadiene-styrene copolymer or polycarbonate with polyethylene terephthalate or polycarbonate with polybutylene terephthalate.

[0047] Polyetheretherketone is characterized by the fact that it is a high-temperature-resistant plastic that contributes to high flame protection.

[0048] Polyethylene is a proven thermoplastic that is excellently adaptable to a variety of requirements. Among other things, polyethylene is thermally formable and weldable, so this material offers a wide range of design and forming possibilities. Polyethylene also exhibits good chemical resistance.

[0049] Polyethylene has the property that its molecular weight can be significantly increased through polymerization, which also increases its wear resistance and impact strength accordingly. This allows high-molecular-weight or ultra-high-molecular-weight polyethylene to be produced with the appropriate molecular weight, allowing the aforementioned properties to be tailored accordingly. This can be achieved, among other things, by replacing carbon-hydrogen bonds (abbreviated to: C-C bonds) and carbon-carbon bonds (abbreviated to: C-C bonds) with bonds between carbon and so-called heteroatoms, e.g., fluorine, nitrogen, and oxygen, as well as more stable aromatic bonds.

[0050] This allows it to be adapted for a wide range of applications for a label according to the invention. For example, and in particular, the heat resistance can be adjusted by increasing the enthalpy of fusion and decreasing the entropy of fusion, thereby adjusting the resistance to high temperatures. High-temperature-resistant plastics, within the scope of the invention, are those plastics or polymers that exhibit high resistance to thermal influences. Furthermore, these plastics exhibit very good mechanical properties, so they remain dimensionally stable even under high thermal influences. Furthermore, they have a high melting point and high tensile strength and rigidity.

[0051] According to the invention, these include polyphthalamides (PPA for short), which can be reinforced with glass fibers and exhibit high mechanical strength and thermal resistance. They have a high heat distortion temperature of over 280°C. They also exhibit low moisture absorption, which can be in the range of 0.1–0.3% by mass. Thus, their physical properties remain virtually unaffected, at least by moisture.

[0052] In this context, the invention proposes polyphenylene sulfide in particular as a predestined high-temperature-resistant plastic. Polyphenylene sulfide is characterized by very high chemical and heat resistance, as well as rigidity. Polyphenylene sulfide is very easy to injection mold, allowing even thin walls to be produced. This makes this material suitable for the creation of delicate shapes. Polyphenylene sulfide can also be combined well with other materials, allowing glass, carbon, and aramid fibers to be embedded in it.

[0053] The invention further proposes the use of a synthetic polymer, with silicones, also known as polysiloxanes or polyorganosiloxanes, being particularly suitable for forming an inventive label. Synthetic polymers can be produced cost-effectively on an industrial scale and can be easily adapted to the requirements placed on an inventive label.

[0054] Silicones offer advantageous properties, including good chemical resistance to many chemicals, as well as high temperature resistance and elasticity at both high and low temperatures. Silicones also exhibit resistance to UV rays and ozone. Furthermore, other materials such as fiberglass can be embedded in silicones to customize the plastic with the desired characteristics.

[0055] Thus, a label according to the invention benefits from the properties of the aforementioned polymers or copolymers, which can also be used in any combination with one another for a label according to the invention and can form the label accordingly. In a further development, the invention provides that the polymer structure has an organic and / or inorganic compound structure at least in sections. The invention thus opens up the possibility of very flexible adaptation of a label in question.

[0056] The invention considers, for example and in particular, that the polymer structure is constructed in the manner of a salt. For example and in particular, at least five highly effective organic compounds can be added to the polymer structure. Within the scope of the invention, for example and in particular, a proportion of up to 25 percent by mass of these aforementioned compounds is provided. Furthermore, metal oxides can be added, for example and in particular up to such an extent, in a plastic made of polypropylene.

[0057] In particular, in a further development of the invention, the invention takes into account that the inorganic compound structure contains or is formed from phosphorus and / or nitrogen.

[0058] Nitrogen offers the property that it can assume a crystalline form and is therefore also available as polymeric nitrogen. According to the invention, nitrogen can be used to improve the durability and strength of the polymer in a label according to the invention and, in particular, to prevent unwanted discoloration or oxidation processes.

[0059] The advantageous use of phosphorus for forming an identification plate according to the invention has already been described previously, so that reference is made to the features described there, which apply here analogously.

[0060] According to the invention, the formation of a flame retardant can also be achieved by modifying the polymer structure, thus eliminating the need for additional additives, fillers, material combinations, and reinforcements such as materials embedded in the polymer. This contributes to the formation of a flame retardant at a late stage in the production of a label according to the invention, and to its targeted and cost-effective implementation.

[0061] Within the scope of the invention, it has been shown that plastic parts exhibit improved properties after irradiation, which can be demonstrated by heat resistance, improved creep behavior, and higher abrasion resistance. Irradiation makes it possible to improve the mechanical, thermal, and chemical properties of an identification plate according to the invention. This makes it possible to cost-effectively improve the properties of a plastic through irradiation, thereby at least meeting the required properties.

[0062] To form a flame retardant, the invention provides a further option for achieving a structural change by means of irradiation. X-rays have proven particularly suitable for this purpose within the scope of the invention. X-rays can be generated cost-effectively, and the duration of the exposure of the plastic to the X-rays determines the type and extent of the formation of the flame retardant through a change in the polymer structure.

[0063] It has been shown that irradiation can be used to modify and improve the properties of a wide variety of plastics. For example, and in particular, thermoplastics, thermoplastic elastomers, and elastomers can be adapted according to the invention.

[0064] To achieve the desired properties, the plastic is irradiated with a predetermined intensity and duration. This depends on the type and extent of the desired change in the plastic's properties. The plastic absorbs the radiation energy, releasing free radicals that, in a molecular bond, create a polymer structure with the desired properties.

[0065] Thus, within the scope of the invention, it is possible to form the flame retardant sectionally, partially, or layer by layer through targeted irradiation. This provides the advantage of forming different areas according to the requirements. The invention thus enables individual adaptation of a label according to the invention.

[0066] Furthermore, it is advantageously possible to achieve the property adaptation in a late production phase and, in particular, to carry out irradiation after the shaping of an identification plate formed according to the invention.

[0067] For this purpose, a corresponding advantageous development of the invention provides that the polymer structure of the plastic is arranged and designed in such a way that the flame retardant is formed by a crosslinking change by means of irradiation, in particular by means of gamma and / or beta irradiation, preferably X-ray irradiation.

[0068] The invention thus enables, for example and in particular, polymer chains to crosslink with one another, thereby transforming the characteristics of a thermoplastic into those of a thermoset. This effectively prevents melting or dissolving of the plastic's structural composite, even at high temperatures, and, for example and in particular under extreme thermal conditions, only carbonization of the plastic is the result. The aforementioned possibilities are advantageously further developed by the invention in that the plastic is designed in such a way that it is at least partially biodegradable. A label formed according to the invention is therefore sustainable and resource-efficient.

[0069] The invention further proposes that a marking plate is formed on the outer layer of the marking body as a flame protection for the underlying plastic, wherein the outer layer is formed in particular by a coating of the marking body.

[0070] The invention thus achieves the advantage that the outer layer can be applied even after molding, and furthermore, the type and extent of the coating determines the flame protection. This enables a labeling plate according to the invention to be tailored to specific requirements, which can also be implemented retrospectively on existing labeling plates.

[0071] According to the invention, the coating can be formed, for example, and in particular, by an aforementioned plastic containing a flame retardant. The flame protection can therefore be formed, for example, and in particular, by a polymer structure of the plastic and / or by a PFAS-substituting additive incorporated into the polymer structure, as described here with reference to the plastic containing a flame retardant. The features described above can therefore be applied analogously to a plastic for the coating.

[0072] The invention takes into account that the coating is also designed and configured for the application of a marking. For this purpose, the coating can be opaque or transparent. Furthermore, the coating in a transparent version can be designed and configured according to the invention such that a marking can be applied to an underlying layer, for example and in particular by means of laser irradiation / laser marking.

[0073] The demands placed on a label can be very high. To effectively meet these demands, an advantageous development of the invention provides that the flame retardants are designed and constructed to at least provide flame protection for the plastic of flame protection class V2, in particular V1, preferably V0, particularly preferably HB, according to UL 94.

[0074] The values ​​determined according to UL 94 are based on an established classification method for plastics by Underwriters Laboratories (UL). This provides a reproducible procedure for assessing and classifying the flammability of plastics. The relevant provisions are incorporated with identical content into the standards IEC / DIN EN 60695-11-10 and -20 and the Canadian CAN / CSA C 22.2 No. 017 in their currently applicable versions.

[0075] The invention thus succeeds in providing an identification plate according to the invention with reproducible and verifiable properties that can be classified accordingly.

[0076] The design of an identification plate can be realized in a variety of ways within the scope of the invention. For example, an advantageous development of the invention makes it possible for the identification elements to be arranged in a composite comprising several identification plates on a plate panel.

[0077] Furthermore, in an advantageous development of the invention, it is determined that the marking body is designed and constructed for non-positive, in particular clamping, holding and / or materially bonded holding, in particular by means of an adhesive layer on the operating means.

[0078] Furthermore, a further advantageous development of the invention provides that the marking body has connecting means that are designed and constructed for locking into a groove of the operating device and / or for a material-to-material bond to the operating device, in particular by means of an adhesive layer, and / or for a form-fitting bond to the operating device, in particular by means of retaining arms arranged so as to be spread apart from one another. In this respect, the invention allows a respective marking plate to be designed for various applications.

[0079] Furthermore, in a further advantageous development of the invention, the marking carrier has a marking surface that is designed and configured for applying a marking by means of irradiation, in particular laser irradiation. This eliminates the need for additional marking aids, as the relevant section for the marking is directly printed or (laser-)irradiated.

[0080] Furthermore, an advantageous development of the invention provides for the marking body to be formed by an injection-molded or extruded plastic body, which allows for cost-effective and rapid production. The invention is explained in more detail below with reference to the accompanying drawing, which shows a selection of exemplary embodiments of marking plates for equipment according to the invention, representative of a multitude of implementation options.

[0081] All features claimed, described and shown in the drawing, taken individually and in any combination with one another, form the subject matter of the invention, regardless of their summary and regardless of their description or representation in the drawing.

[0082] Therefore, the features are not bound to the constellations explained below and shown in the figures, but can also form an identification plate according to the invention in isolation from one another, as well as in a different combination.

[0083] The figures in the drawings each show the aforementioned exemplary embodiments in a schematic representation. Therefore, the representations in the figures are not necessarily to scale, so the scales used in the figures may also differ from one another.

[0100] Illustrate another embodiment of the identification plate.

[0101] In the following, where the structure is the same or similar, the description is reduced to the differences between the embodiments or representations in the figures for the sake of clarity.

[0102] The features illustrated in the figures also apply analogously or analogously, both comprehensively and in isolation from one another, to various embodiments as well as to other identification plates formed according to the invention. The invention is not limited to the described and illustrated embodiments or contexts. Fig. 1 and Fig. 2 show a first embodiment of an identification plate 2 for an operating device 4, which is intended for attachment to a base body 5 of the operating device 4.

[0103] The operating means 4 is represented in Fig. 1 and Fig. 2 in sections and schematically by a wall section of a base body 5, which forms a housing 5'.

[0104] The identification plate 2 has a marking body 6 with a marking carrier 7 for applying a marking 8 and a holding device 9 for holding the marking body 6 on the housing 5' of the base body 5.

[0105] The marking body 6 also has a transparent section 10 for arranging the marking 8, which forms the marking carrier 7.

[0106] The marking carrier 7 serves to apply a marking 8 to the marking body 6 and is formed in this example by the aforementioned transparent section 10 of the marking body 6.

[0107] The transparent section 10 consists of a plastic 12 containing a flame retardant that is free of a perfluorinated and / or polyfluorinated alkyl compound. The flame retardant is formed by a polymer structure of the plastic. The polymer structure of the plastic 12 was irradiated with X-rays to form the flame retardant through a crosslinking change in the plastic.

[0108] Furthermore, the marking body 6 has a lower part 16, which, when attached, is arranged on an upper part 14. The marking body 6 is accordingly formed from several layers 14, 16. The upper part 14 forms a cover layer that covers the lower part 16. The upper part 14 comprises the same plastic with the flame retardant from which the transparent section 10 is made.

[0109] The lower part 16 is also formed from a plastic 12 containing a flame retardant, with the flame retardant being formed by a PFAS-substituting additive incorporated into the polymer structure, the additive consisting of a phosphorus substance. In this exemplary embodiment, the marking 8 is arranged between the upper part 14 and the lower part 16 when attached. The marking 8 consists of a laser marking 8', which is applied directly to a side 20 of the transparent section 10 facing the lower part 16.

[0110] For this purpose, the transparent section 10 is designed and constructed as a marking carrier 7 for applying the marking 8 by laser marking.

[0111] The marking 8 is such that it can be visually detected from outside the marking plate 2 by an optical sensor (not shown), such as a camera.

[0112] In this exemplary embodiment, the plastic 12 is again a plastic 12 containing a flame retardant, with the upper part 14 (except for the transparent section 10) and the lower part 16 being opaque. The flame retardant is formed by the plastic 12 being a high-temperature-resistant plastic 12.

[0113] As shown in Fig. 1, the transparent section 10 forms in this embodiment a section 22 of the upper part 16, whereby a viewing window 22' is formed.

[0114] In the attached state, the upper part 14 is connected to the lower part 16 by an adhesive 24 arranged between them, whereby this is done in a materially bonded manner in this embodiment.

[0115] In this embodiment, the adhesive 24 is applied to the side 26 of the lower part 16 facing the upper part 14 in the attached state, which side is formed by two adhesive sections 24'.

[0116] In a further alternative, the adhesive 24 can, for example, also be arranged on both of the aforementioned sides 20, 26. Furthermore, the adhesive 24 can be applied to the respective side 20, 26 in sections or over the entire surface.

[0117] The implementation of an adhesive 24 is possible in a variety of ways within the scope of the invention, so that the possibilities mentioned in the exemplary embodiments are examples to which an implementation according to the invention is not limited. As can be seen from Fig. 1, the upper part 14 with the transparent section 10 arranged thereon completely covers the marking 8, 8' attached thereto when attached. The transparent section 10 is in turn formed using a transparent bio-based polymer.

[0118] In the first embodiment, the upper part 14 and the lower part 16 are formed by plate-shaped elements 28, 28' which are designed substantially congruent to one another and between which the marking 8 is arranged.

[0119] In Fig. 2, the components of the identification plate 2 from Fig. 1 are shown in an attached state, in which the components (4 to 28, 28') of the identification plate 2 previously described in Fig. 1 are arranged next to one another and are thus prepared for attachment to the equipment 4 to be marked.

[0120] The transparent section 10 protects the marking 8 from external environmental influences and also ensures optical detection of the marking 8 from the outside, for example by an optical sensor (not shown).

[0121] The holding device 9 uses an adhesive layer (not shown) to hold the marking body 6 to the operating device 4 or its base body 5 or housing 5', which is arranged between the marking body and the housing 5'. This type of holding will be explained below using the further exemplary embodiments.

[0122] Fig. 3 shows a second embodiment of an identification plate 2 for identifying an operating device 4, in which the upper part 14 is formed from a film or film body 30 and the lower part 16 from an extruded plastic body 32. In this embodiment, the upper body 14 forms the identification carrier 7.

[0123] The lower part 16 is a component of the holding device 9 and is designed such that, in an attached state in which it is arranged or held according to the invention on the base body 5 or housing 5' to be marked, its underside 34 is held in a groove 35 on the base body 5 or housing 5'. Thus, the underside 34 of the lower part 16 is a side 34' of the marking body 6 facing the base body 5 or housing 5' to be marked in the attached state.

[0124] For a positive holding in the groove 35, a spreading foot 34" is formed on the underside 34 of the lower part 16 as a functional part of the holding device 9, which is formed by two holding arms 34", 34" which can be spread apart from one another.

[0125] Fig. 4 illustrates, in an attached state, a third embodiment of an identification plate 2 for an operating device 4. In the attached state shown in Fig. 4, the identification body 6 is arranged on a housing 5' extending along an axis 38, which forms a cylindrical hollow body 36 for the conduction of a fluid which is arranged between the upper part 14 and the lower part 16.

[0126] The housing 5' (or the hollow body 36) is cylindrical in shape and, in this exemplary embodiment, has an oval cross-section. It extends longitudinally along an axis 38 (body axis). Due to the selected cross-sectional representation, the longitudinal extent of the hollow body 36 is directed into the plane of the drawing, so that a free end 40 of the hollow body 36 with the identification plate 2 arranged thereon is shown.

[0127] The hollow body 36 is correspondingly hollow in its interior 42 and forms a tube 36' for conveying fluids or bulk materials (not shown). Within the scope of the invention, fluids can be both gaseous and liquid substances. Bulk materials within the scope of the invention include pourable materials, such as, in particular, powders, granules, grains, cereals, gravel, sand, and the like.

[0128] In another application or embodiment, the hollow body 36 can be formed in the manner of a hose, which provides a sheath for accommodating one or more electrical wires, thus forming a 36" cable (see Fig. 7). In a cable, the 36" wires or strands are located inside the cable, by means of which the electrical conduction takes place by forming corresponding conductor bodies for the electrical current or corresponding signals. Thus, signal transmission is also possible with these.

[0129] The marking body 6 consists of an upper part 14 and a lower part 16, which are made of a plastic 12 containing a flame retardant, are bowl-shaped, and are held together by means of holding means 44. The plastic 12 is designed as in the previously described embodiment.

[0130] The upper part 14 and the lower part 16 as well as the holding means 44 are components of the holding device 9 with which the identification carrier 7 is arranged and held on the operating means 4.

[0131] In this case, the retaining means 44 are designed as a screw connection. Within the scope of the invention, the retaining means 44 may also comprise or be formed by snap-in or locking means, rivets, adhesives and adhesive tapes, and the like, regardless of the exemplary embodiments described here.

[0132] Furthermore, it is possible to form the holding means 44 by means of a film hinge. Thus, in this exemplary embodiment, the upper part 14 is held together by two screws 44' on the lower part 16, whereby they are clamped to the hollow body 36 in the illustrated mounting state.

[0133] The transparent section 10 is arranged on a side 48 of the marking body 6 or upper part 14 facing away from the hollow body 36 and is formed by a coating 10', which covers the marking 8 applied to the upper part 14 and forms a seal for the marking 8, protecting it from external influences and tampering. The coating 10' covers the upper part 14 in a section 46 in which the marking 8 is arranged.

[0134] The coating is thus an outer layer (10") formed on the marking body (6), which is designed and constructed as a flame retardant. Thus, a flame protection for the underlying plastic is formed on the outer layer (10") of the marking body (6), wherein the outer layer (10") in this embodiment is formed by a coating (10') of the marking body (6).

[0135] In this exemplary embodiment, the marking 8 is printed directly onto the upper part 14 by means of inkjet printing. The marking 8 is arranged on a side 48 of the upper part 14 or the marking body 6 facing away from the object 36 when attached.

[0136] The upper part 14 and the lower part 16 each consist of the same opaque

[0137] Plastic 12, which forms the flame protection in the plastic 12 by means of a high-molecular-weight polyethylene. According to the invention, the upper part 14 and the lower part 16 (both or only one of them) can also be made of the same plastic 12, 12' as that of the transparent section 10 and can also be transparent.

[0138] Fig. 5 illustrates a fourth embodiment of an identification plate 4 for an operating device 4 in an attached state. The identification body 6 is formed from a film as a film body 30, which is arranged on the hollow body 36 to be marked by means of holding means 44 of the holding device 9.

[0139] The holding means 44 is formed by an adhesive 44". The adhesive 44", in turn, is an adhesive layer 44'" (symbolized by a dashed circumferential line) which is arranged between the cylindrical hollow body 36 to be marked and the marking body 6 and connects them to one another.

[0140] On a side 48 (top side 48) of the marking body 6 facing away from the cylindrical hollow body 36 to be marked in the shown attachment state, the transparent section 10 is arranged, on which the marking 8 is arranged by a marking element 50 in the form of a printed adhesive label 50'.

[0141] In this exemplary embodiment, the marking body 6 is designed and constructed to circumferentially wrap around a cylindrical hollow body 36 to be marked, such as a cable, a hose, a rod, or the like. In this exemplary embodiment, the hollow body 36 to be marked is a pipe 36'.

[0142] As Fig. 5 illustrates, according to the invention the circumferential winding is directed in the circumferential direction U to the body axis 38, along which the housing 5' to be marked (or in this embodiment the cylindrical hollow body 36 to be marked) is longitudinally extended.

[0143] According to the invention, however, the circumferential wrapping does not have to be complete, but can also comprise a circumferential section, and can therefore also be partially circumferential.

[0144] Fig. 6 illustrates a fifth embodiment of an identification plate 2 in an attached state, wherein, in contrast to the fourth embodiment, this plate has a marking 8 which is arranged on the side 34' facing the hollow body 36 to be marked in the attached state shown.

[0145] The transparent section 10 is formed integrally in a section 46 of the marking body 6 and in turn provides protection and a viewing window 22 for the marking 8 by covering the marking 8. The marking 8 is in turn a marking element 50 in the form of a printed adhesive label 50'.

[0146] Fig. 7 shows an attachment state of a sixth embodiment of an identification plate 2 for an operating means 4, in which the transparent section 10 extends along the upper part 14 of the identification body 6.

[0147] The marking body 6 is formed by a multi-layer film body 30 and is arranged and designed such that the upper part 14 and the lower part 16 are integrally connected to one another.

[0148] The marking body 6 is designed and constructed for circumferentially wrapping a cylindrical base body 5 or housing 5' of the operating means 4, which may in turn be, for example and in particular, a hose, a pipe 36', a rod, a cable and the like.

[0149] In the mounted state shown in Fig.7, the cylindrical hollow body 36 to be marked is a cable 36", which serves as a component of one of the operating means 4 in a switch cabinet (not shown) for electrical / data transmission.

[0150] The 36" cable contains wires or strands (not shown) for the electrical conduction. The wires or strands are made of or contain a copper material. In addition to transmitting electrical energy, the electrical cable can also be used to transmit data or signals.

[0151] As Fig. 7 again illustrates, according to the invention, the circumferential wrapping is directed in the circumferential direction U toward the body axis 38, along which the base body 5 or the housing 5', in this case the cylindrical object 36 to be marked, is longitudinally extended. This exemplary embodiment illustrates that the marking body 6 is designed and constructed for the complete circumferential wrapping of the base body 5 or the housing 5' of an operating device.

[0152] The upper part 14 is formed at a free end 52 and the lower part 16 at a further free end 54 of the marking body 6, wherein the free ends 52, 54 are opposite ends 52, 54 of the marking body 6.

[0153] In this case, one free end 52 of the marking body 6 overlaps the other free end 54 of the marking body 6 in an overlap section 56.

[0154] Fig. 8 shows the sixth embodiment of an identification plate 2 according to the invention from Fig. 7 in a longitudinal extension.

[0155] The extension of the upper part 14 and the lower part 16 in the shown alignment direction, in which they are arranged next to one another - as illustrated in Fig. 8 - is dimensioned such that in the attachment state shown in Fig. 7, in which the marking body 6 is arranged on the housing 5', a free end 52 of the marking body 6 overlaps at least partially another free end 54 of the marking body 6 in an overlap section 56 (illustrated in Fig. 7).

[0156] Fig. 9 shows a seventh embodiment of an identification plate 2 according to the invention, whose identification body 6 is again formed from a strip-shaped film body 30. The identification body 6 is divided into an upper part 14 and a lower part 16. In this embodiment, the upper part 14 and the lower part 16 are integrally connected to one another in a connecting section 58.

[0157] A straight fold line 60 is formed on the connecting section 58, along which the upper part 14 and the lower part 16 can be folded towards one another in such a way that the upper part 14 and the lower part 16 overlap in sections and, in this embodiment, essentially congruently in the folded state shown in Fig. 9.

[0158] In this embodiment, the fold line 60 is formed by a notch-shaped indentation 61 that extends transversely to the longitudinal extent of the marking body 6. According to the invention, in similar or differently designed embodiments of the invention, the fold line 60 can be formed not only by an indentation 61 but also, among other things, by a groove, a (linear) perforation, an embossing, and the like.

[0159] Fig. 10 illustrates an eighth embodiment of an identification plate 2 according to the invention, again in an attached state in which it is arranged on a transparent housing 5' of an operating means 4, shaped as a container 36".

[0160] The marking 8,8' is arranged on a side 34' of the marking body facing the housing 5', whereby both the fill level of the housing 5' and its surroundings can be better detected.

[0161] Within the scope of the invention, a housing 5' of an operating means 4 can be designed in any desired manner, so that the shape is not limited to a cylindrical design.

[0162] Fig. 11 illustrates a use of a shield cap 68 for providing an arrangement of marking bodies 6 for marking equipment 4.

[0163] Accordingly, the invention comprises the provision of identification bodies 6 of identification plates 2 by means of a plate cap 68, from which the identification bodies 6 are separated or separated for attachment to an operating means 4 or its base body 5, or a housing 5', respectively, and are then attached or arranged accordingly on the operating means 4 or its base body 5, or a housing 5'.

[0164] For a better overview, the identification plates 2 or the identification bodies 6 are marked with the relevant reference symbols once in Fig. 11 as representatives of the others.

[0165] In this exemplary embodiment, the shield cap 68 has a plurality of marking units 70 arranged one behind the other in a row, each marking unit 70 in turn having a transverse web 72 and a plurality of marking bodies 6 formed on the transverse web 72. The marking units 70 arranged one behind the other in a row are connected to one another via a frame 76, which runs laterally along the marking units 70. The frame 76 is provided to the right and left of the marking units 70 along their transverse side surfaces.

[0166] To guide the label panel 68 in a printer in which the marking units 70 in the section 46 for marking are marked or printed, guide means 78a, 78b are provided on the frame 76. As can be seen in Fig. 12, these guide means are each formed from two webs 80a, 80b arranged parallel to one another, so that the guide means 78a, 78b are essentially U-shaped. Two guide means 78a, 78b are arranged on the frame 76, with a first guide means 78a being arranged to the left of the transverse side of the marking units 70 on the frame 76 and a second guide means 78b being arranged to the right of the transverse side of the marking units 70 on the frame 76.

[0167] As shown in Fig. 11, a plurality of recesses 88 in the form of notches are provided along the webs 80a, 80b. Control holes 84 and identifiers 86 are also provided on the frame 16, wherein the identifier 86 can be in the form of a 10-bit code.

[0168] The sign panel 68 is manufactured from a polymer composition by an injection molding process. The injection molding process occurs at the transverse web 72 of the marking units 70, whereby in the embodiment shown in Fig. 11, the injection point 88 (representatively marked once in Fig. 11) is provided centrally along the longitudinal direction of the transverse webs 72.

[0169] The sections 46, in each of which the marking is arranged, can be provided on the transverse web 72 and / or the marking bodies 6 of a marking unit 10.

[0170] The webs 80a, 80b are arranged essentially parallel to one another, whereby the guide means 78a has a U-shaped configuration in the form of a runner. The side surfaces 90a, 90b of the webs 80a, 80b are each provided with a bevel, wherein in the embodiment shown here the webs 80a, 80b have a bevel on both their side surface 90b and their side surface 90a. The bevel can extend over the entire length of a side surface 90a, 90b or be provided only in certain regions. The bevels are designed such that the cross-sectional area of ​​the webs 80a, 80b decreases towards their free end. The beveled side surfaces 80a, 80b enable easier demolding of the shield cap 68 from the injection mold (not shown) in the region of the guide means 78a, 78b.

[0171] At the connecting area between the frame 76 and the marking unit 70, a predetermined breaking point in the form of a material reduction is formed.

[0172] Fig. 13 illustrates a further embodiment of an identification plate 2 in an arrangement on a plate cap 68 in a schematic representation in a perspective view of an upper side (Fig. 13) and a lower side (Fig. 14).

[0173] For better clarity, the identification plates 2 and the identification bodies 6 are identified with the corresponding reference numerals in Fig. 13, representing the other components. The same applies to the illustrated splay feet 34".

[0174] Compared to the arrangement shown in Fig. 11 and Fig. 12, this arrangement lacks a frame for the shield cap 68. The individual marking bodies 6 of a respective marking plate 2 are arranged on a support body 90, which has a central strand 92 from which transverse webs 72 are provided for the arrangement of the marking bodies 6. The central strand 92 and the transverse webs 72 are arranged transversely to one another.

[0175] The marking bodies 6 can be removed from the support body 90 according to the procedure explained with reference to Fig. 11 or Fig. 12 and used for attachment to the base body 5 or housing 5' (not shown in Fig. 13 / 14).

[0176] The invention shows its advantages in many forms and applications, of which the ones presented above are only examples.

[0177] The invention is therefore not limited to the configurations and features described and shown in the figures. In this respect, the features of the exemplary embodiments or configurations can also be used in isolation in another configuration according to the invention and are therefore not tied to the configurations shown and described, but can also be used independently of them and across all examples. In this context, it should be noted that the invention also finds application in an operating device as such, as well as electrical and electronic components and assemblies, their components, in particular their housings, and thus a flame retardant can be formed that can be implemented analogously to the flame protection illustrated by an identification plate. The design of a plastic comprising a flame retardant can therefore be implemented analogously for other objects.

[0178] Therefore, the possibilities for creating flame protection illustrated by a label are applicable and transferable to other components, assemblies and equipment, regardless of the described design of an object, so that the flame protection agents described here can also demonstrate their effectiveness there and design them accordingly.
