Description

[0001] Marking mat for marking electrical components and method for their production

[0002] The invention relates to a marking mat for marking electrical components and a method for producing such a marking mat.

[0003] Such marking mats feature multiple marking labels used to label electrical components, such as terminals, connectors, or cables, as well as electronic devices. A marking specific to the product to be marked is printed on a labeling surface of a marking label. For this purpose, the marking labels are produced together, for example, as a marking mat, so that multiple marking labels can be labeled together using a single labeling device, such as a printer.

[0004] These marking mats and marking signs are typically designed to meet the high standards for proper use common in the industrial sector. In particular, they are often designed to withstand the effects of external environmental influences.

[0005] Typically, marking mats with identification plates are made of a (thermoplastic) polymer or metal. Polymers have established themselves very early in the industrial sector as cost-effective and easily moldable materials for a variety of areas and tasks, covering a very wide range of applications. However, the problem with plastic materials is that they can pose a significant environmental impact. Furthermore, the identification plates are sometimes subject to frequent replacement, for example, after maintenance or product-specific label changes, and can thus lead to high levels of waste.

[0006] The object of the present invention is to improve the environmental compatibility in connection with the labeling of electrical components.

[0007] This problem is solved by an object having the features of claim 1.

[0008] Accordingly, a marking mat, in particular for marking electrical components, is provided with one or more marking plates, wherein the marking mat is made at least partially, in particular completely, from a material which comprises (or consists of) a plastic which is a polymeric secondary raw material and / or a biodegradable polymer and / or a bio-based polymer (e.g. made from regeneratively and / or biologically produced synthesis gas and / or liquids and / or general reactants).

[0009] This is based on choosing from a selection of plastics that can be used alone or in combination to increase the environmental compatibility of a marking mat or marking plates and thus reduce their environmental impact. This provides a marking mat with a significantly improved environmental balance. The invention solves its stated problem through a material-based approach to reducing environmental impact. In particular, the invention moves away from the approach of replacing a plastic material with another material, such as metal. Furthermore, existing marking systems can continue to be used without any modifications being necessary.

[0010] This is achieved by providing a selection of plastics that are recyclable and / or biodegradable and / or made from renewable resources. The selection is thus not limited to any one of the aforementioned plastics, meaning they can also be combined with one another.

[0011] The material can consist of at least one of the aforementioned plastics, but can also contain other material additives, such as additives or other polymers or polymer components. Furthermore, composite materials can also be used for the material. Furthermore, it is possible to mix the aforementioned plastics with other components, such as additives or primary polymers.

[0012] The marking mat described herein makes it possible not only to significantly reduce environmental impact but also to significantly reduce the burden on raw material resources. Furthermore, the marking mat can meet the sometimes more stringent requirements for the usability of the corresponding marking plates, e.g., with regard to temperature resistance, which are usually met with primary materials. However, marking plates are typically replaced more frequently than the components they mark. Based on this finding, it has been shown that the aforementioned materials, which are more environmentally friendly than conventional engineering thermoplastics made from fossil raw materials, can be used for marking plates. The material can include a laser additive.The laser additive can be designed to make the marking mat and / or the marking plates inscribable by means of a laser after the marking mat has been manufactured. For example, the laser additive can be activated by a laser. The laser additive can be activated by means of a laser and thus enable or facilitate, in particular enhance, the creation of an inscription, e.g. an image and / or text, on the surface of a marking plate. Furthermore, the laser additive can be designed to compensate for fluctuations in the marking quality resulting from a previous recycling process of one or more material components. The laser additive thus enables particularly good and uniform inscribability of the marking plates of the marking mat after their manufacture.In particular, this approach can reduce waste from, for example, incorrectly labeled identification plates, thus further improving the environmental impact. Furthermore, it can also make it possible to use certain particularly environmentally friendly materials for identification plates in the first place. The material can form a plastic matrix in which the laser additive is embedded. The laser additive can be distributed throughout the entire material. The laser additive can be mixed into the material, for example.

[0013] For example, the color of the laser additive can be changed using a laser. In this case, a color change and / or a color change can be enabled, or in particular enhanced, by the laser additive. For example, a previously colorless laser additive becomes colored when exposed to laser light. This allows for good labeling. Alternatively or additionally, the laser additive can increase the absorption capacity of the plastic matrix for the laser light.

[0014] The marking is preferably a printing process and can be performed by a marking device, preferably a printer. The printer can contain a laser. In one example, the laser is an infrared laser, in particular with a wavelength of 1064 nm.

[0015] The laser additive can be introduced into the material, especially into the plastic, using a masterbatch. A masterbatch is, for example, a concentrate of one or more additives, in this case the laser additive, perhaps in the form of plastic-based granules. The concentration of the additives in the masterbatch is optionally higher than their concentration in the desired end product, in this case the marking mat. The masterbatch allows the provision of pre-concentrated laser additives in the form of granules, which are mixed into the plastic (raw polymer). The laser additive can also be introduced via extrusion or a similar process of a compound, also known as compounding. This differs from a masterbatch in that it is used in subsequent processing without further dilution of the concentration of the laser additive in the plastic, since the laser additive is already present in the desired final concentration.

[0016] The introduction of the laser additive via a masterbatch or by compounding enables a particularly homogeneous distribution of the laser additive and thus a particularly efficient and uniform laser marking with a suitable laser.

[0017] Optionally, the material comprises several different plastics. Each of the several different plastics can be a polymeric secondary raw material, made from biologically produced synthesis gas, from biologically produced synthesis fluids, and / or from biologically produced synthesis reactants, and / or be biodegradable.

[0018] For example, the material comprises a polymeric secondary raw material and a renewable raw material. Or the material comprises a polymeric secondary raw material and a biodegradable raw material. Or the material comprises a renewable raw material and a biodegradable raw material. Or the material comprises a polymeric secondary raw material and a renewable raw material and a biodegradable raw material. Optionally, one and the same plastic in the material is both a polymeric secondary raw material and a renewable raw material. Or one and the same plastic is both a polymeric secondary raw material and a biodegradable raw material. Or one and the same plastic is both a renewable raw material and a biodegradable raw material. Or one and the same plastic is both a polymeric secondary raw material and a renewable raw material and a biodegradable raw material.This makes it possible to provide particularly environmentally friendly marking mats.

[0019] The polymeric secondary raw material can be a conventional and / or chemically recycled thermoplastic. Conventionally recycled thermoplastics are, for example, mechanically recycled and / or produced by melting. Conventionally recycled thermoplastics typically differ from corresponding primary, i.e., non-recycled thermoplastics in their correspondingly shorter polymer chains. Conventionally recycled materials regularly differ from standard materials in their additional thermal stress, as the polymers are typically melted at least once more than the original standard material. If additional granulation processes are planned before the second processing / use, the additional thermal stress / damage can be further intensified. Certificates for a reduced CC^ content are typically issued for chemically recycled materials.Usually, this allows a corresponding CO2 reduction to be claimed retrospectively.

[0020] For example, the material consists of at least 25% by weight of the plastic, which is a conventionally and / or chemically recycled thermoplastic, in particular at least 50% by weight or even 100% by weight. This enables a substantial improvement in the environmental balance, especially the so-called CO2 footprint of the material.

[0021] Optionally, the polymeric secondary raw material is a conventionally recycled thermoplastic, which can be an engineering thermoplastic. For example, the polymeric secondary raw material is a conventionally recycled thermoplastic and / or selected from the group consisting of polycarbonate, polyamide, polyethylene, polyethylene terephthalate, polyvinyl chloride, and polypropylene. These materials enable particularly good properties for many applications.

[0022] Optionally, the material consists of 10 to 100 wt.% (or 10 to 80 wt.%) of the plastic produced from renewably and / or biologically produced synthesis gas and / or liquids and / or reactants. This makes it possible to provide a particularly resource-efficient marking mat.

[0023] For example, the plastic of the material is made from regeneratively and / or biologically produced synthesis gas and / or liquids and / or reactants, with the renewable raw material being selected from sugar, starch, protein, cellulose, lignin, fat, and / or vegetable oil, particularly castor oil and rapeseed oil. This generally includes regeneratively or biologically produced synthesis gases and synthesis liquids used as reactants for the plastic formulation (e.g., biogas, biomethanol, bioliquids, organic waste, etc.). This provides particularly environmentally friendly yet robust labels for identification purposes.

[0024] The plastic of the material can be made from regeneratively and / or biologically produced synthesis gas and / or liquids and / or reactants and can be in the form of polylactide, polyhydroxyalkanoate, cellulose derivatives, especially cellulose esters or cellulose butyrate, polyethylene, starch derivatives, polyurethane, TPU, TPS, polycarbonate, polyamide, polyethylene, polyethylene terephthalate, polyvinyl chloride, polybutylene terephthalate, polyester, and polypropylene, as well as their blends and copolymers. This also enables an environmentally friendly yet robust marking mat.

[0025] The plastic used for the material is optionally biodegradable and can be in the form of polybutylene adipate terephthalate, polyhydroxyalkanoate, polylactide, starch blend, or polyester. This allows the printed or unprinted labels, as well as any remnants of the label mat, to be easily composted after removal, particularly after breaking the labels out of the label mat after use, optionally with the inclusion of additives for composting. This makes disposal particularly environmentally friendly.

[0026] For example, the marking labels on a marking mat are arranged along two perpendicular dimensions, each aligned in a row. This enables particularly reliable and consistent marking of the marking mat after its production in a dedicated printer, thus significantly reducing waste due to incorrect markings.

[0027] In one embodiment, the identification plates are molded onto one or more crosspieces. In particular, several identification plates are molded onto a (common) crosspiece. The one crosspiece and the several identification plates molded onto it can form a marking unit. In this way, a large number of identification plates per marking mat are (each) connected to form a few marking units.

[0028] The marking units can be connected to each other via a frame. Such a design of marking units connected via a frame facilitates (joint) labeling in an associated labeling device, such as a printer.

[0029] Optionally, the identification plates are each connected to the rest of the identification mat via a predetermined breaking point. The predetermined breaking point can be in the form of a reduction in the material, e.g. a material taper or a perforation in the connection area. The predetermined breaking point enables simplified separation, in particular breaking out of the identification plates from the identification mat, especially after the identification plates have been written on, and thus simple handling. For example, predetermined breaking points can be provided between a crossbar and the identification plates molded onto it. The identification mat can have guide means for guiding the identification mat in a printer. In particular, the guide means are arranged on the frame. The guide means serve to hold and / or convey the identification mat during printing by a printer.For this purpose, the printer can have a corresponding holder that can be engaged with the guide means of the marking mat.

[0030] The marking mat can be rigid. For example, the marking mat is a plate.

[0031] According to one aspect, a method for producing a marking mat, in particular for marking electrical components, with one or more marking plates is specified. The method comprises providing a material that comprises a plastic, wherein the plastic is (or is being) produced by recycling a thermoplastic, is bio-based, e.g., is (or is being) produced from regeneratively and / or biologically produced synthesis gas(es) and / or liquid(s) and / or reactant(s), and / or is biodegradable. The method further comprises forming the marking mat at least partially, optionally completely, from the material. With regard to the advantages, reference is made to the above information on the marking mat. Using the method, the marking mat can be formed according to any embodiment described herein.

[0032] The material may comprise a laser additive that enables the marking plates to be inscribed using a laser, particularly an infrared laser, after the marking mat has been manufactured. Regarding the advantages, reference is made to the above information.

[0033] Optionally, the plastic is produced through chemical recycling of a thermoplastic. This enables particularly high performance and quality of the plastic while simultaneously achieving a particularly good environmental impact. Alternative or additional conventional recycling may include shredding. Chemical recycling includes, for example, solvolysis, depolymerization, pyrolysis, and / or gasification. This allows for the production of particularly high-quality recycled thermoplastics.

[0034] The marking mat can be formed by injection molding. This enables particularly simple production in large quantities. According to one aspect, a method for producing labeled marking mats is provided. The method comprises providing a marking mat according to any embodiment described herein, in particular by producing a marking mat according to the method described above in any embodiment, and printing the marking plates with a printer, in particular using a laser of the printer.

[0035] The concept underlying the invention will be explained in more detail below with reference to the exemplary embodiments illustrated in the figures. They show:

[0042] Fig. 5 is a schematic sectional view of a printer for labeling a

[0044] Fig. 6 shows a method for producing a marking mat.

[0045] Fig. 1 to 4 show various marking mats 1, T, 1", each with several marking plates 10 for marking, for example, electrical components.

[0046] The marking mats 1, T, 1" are generally at least partially made of a material comprising a plastic which is (a) a polymeric secondary raw material and / or (b) produced from regeneratively and / or biologically produced synthesis gas and / or liquids and / or reactants and / or (c) biodegradable. The polymeric secondary raw material is, for example, a conventionally (e.g. mechanically and / or by melting) and / or chemically recycled thermoplastic. The material consists, for example, of at least 25 wt.% of the polymeric secondary raw material. The polymeric secondary raw material can be an engineering thermoplastic, in particular polycarbonate, polyamide, polyethylene, polyethylene terephthalate, polyvinyl chloride or polypropylene.Thermoplastics have the advantageous property of good formability and processability, as they can soften to the point of flow, for example, through the application of heat, making them easily moldable. After a cooling phase, they become solid again and retain their shape.

[0047] Industrial plastic waste is often available in large quantities and is often sorted separately, which minimizes the need for sorting or cleaning, and makes it immediately available for recycling. For example, it is shredded and can then be reused to form the 1, 1', 1" marking mats. Optionally, used marking plates are used to produce the material.

[0048] Furthermore, the material can consist of 10 to 100 wt.% of the plastic produced from renewably and / or biologically produced synthesis gas and / or liquids and / or reactants. The renewable raw material can be sugar, starch, protein, cellulose, lignin, fat and / or vegetable oil. In particular, the renewable raw material can be castor oil. Bio-based polymers are also referred to as technical biopolymers and can be produced from biogenic raw materials, preferably renewable plant raw materials. Biowaste can also be used for this purpose, thereby further increasing or improving sustainability. Available renewable raw materials include, for example and in particular, rapeseed and corn, which are available or can be cultivated in large quantities. A bio-based polymer that is also biodegradable is particularly environmentally friendly.Examples of bio-based polymers include polybutyrate adipate terephthalate (PBAT), so-called starch-based biodegradable blends or polylactide (PLA), polyhydroxyalkanoates (PHA), cellulose derivatives such as cellulose esters (CA) and cellulose butyrate (CAB), so-called biodegradable polyesters, and starch derivatives. These polymers also include bio-polyethylene and can match the properties of conventional polyethylene based on a fossil raw material (primary polymer).

[0049] Furthermore, the plastic of the material can be biodegradable and be present, for example, in the form of polybutylene adipate terephthalate, polyhydroxyalkanoate, polylactide, starch blend, or polyester. A biodegradable portion of the material can be detected by carbon detection. A material is biodegradable in particular if the degradation in question occurs through a chemical process in which microorganisms present in the environment convert the material into natural substances such as water, carbon dioxide, and compost (where artificial additives are not required). The process of biodegradation depends on the environmental conditions (e.g., location or temperature), the material, and the application. Biodegradable polymers include, among others, PBAT, PLA, and PHA.

[0050] Biodegradable plastics can be enhanced with additional properties using additives based on fossil or renewable raw materials, allowing for additional, possibly specific material properties compared to conventional polymers, such as desired labeling and / or printability, light resistance, water vapor permeability, or even biodegradability. These polymers thus open up a broad spectrum of applications through specific adaptation of the material.

[0051] In the examples of Fig. 1 and 2, the material of the respective marking mat 1, T consists of polyamide.

[0052] The marking mats 1, T, 1" each comprise a plurality of marking plates 10. The marking plates 10 each have a labeling surface 100 which can be labeled, for example in a printer 2.

[0053] The identification plates 10 are arranged in a plurality of rows R1 extending along a (first) dimension D1. The rows R1 of identification plates 10 are further arranged in rows R2 along a (second) dimension D2 perpendicular to the (first) dimension D1. The identification plates 10 can be directly adjacent to one another in both dimensions D1, D2 (as in the example of the identification mat 1" according to Fig. 4), can be lined up at a distance from one another in both dimensions D1, D2 (as in the example of the identification mat 1' according to Figs. 2 and 3), or can be directly adjacent to one another in one dimension D1 and lined up at a distance from one another in the other dimension D2 (as in the example of the identification mat 1 according to Fig. 1).

[0054] In the exemplary embodiments according to Figs. 1-3, a plurality of identification plates 10, specifically a row R1 of identification plates 10, are arranged, in this case integrally formed, on a transverse web 11. The transverse webs 11, together with the identification plates 10 arranged along a row R1, each form an identification unit K. The identification units K are arranged in a row, one behind the other, spaced apart from one another, in the example shown along the (second) dimension D2. However, it is also possible for the identification units K to be directly adjacent to one another.

[0055] The marking units K are connected to one another via a frame 12. The frame 12 extends laterally, in particular on both sides, along the marking units K, in particular along the transverse sides of the marking units K, in the example shown along the (second) dimension D2.

[0056] In the example shown, the marking mat 1 has guide means 14a, 14b for guiding it through a printer 2 (see Fig. 5), in which the marking plates 10, in particular their labeling surfaces 100, can be printed. In this case, the guide means 14a, 14b are arranged on the frame 12. The marking plates 10 are arranged between the guide means 14a, 14b.

[0057] The guide means 14a, 14b are each designed in the form of a runner. The parallel arrangement of the guide means 14a, 14b shown enables particularly secure, particularly tilt- and twist-proof, guidance of the marking material 1 in the printer 2.

[0058] The marking material T according to Figs. 2 and 3 further comprises a predetermined breaking point 13 in the connecting area between the frame 12 and the marking unit K, in particular between the frame 12 and the crosspiece 11 of the respective marking unit K. The predetermined breaking point 13 is designed as a material reduction. The predetermined breaking point 13 enables easy removal of a marking unit K from the frame 12, in particular after printing in a printer 2.

[0059] Furthermore, in the example shown, additional predetermined breaking points 15 are provided between a transverse web 11 and the identification plates 10 formed thereon. These are also designed in the form of a tapered material. These predetermined breaking points 15 enable easy separation of the individual identification plates 10 from the respective transverse web 11, particularly after the identification plates 10 have been printed in the printer 2. The individual identification plates 10 of the identification mats 1, 1' of Figs. 1-3 each have locking elements. Using the locking elements, the identification plates 10 can each be locked to an electrical component or the like.

[0060] In the identification mat 1" shown in Fig. 4, the identification plates 10 are directly connected to one another in both dimensions D1, D2. The identification plates 10 are embedded in a frame 12 and directly connected to the frame 12. In this variant, the identification mat 1" is designed in particular as a (flat) plate, in particular as a plate. Between the identification plates 10, linearly extending predetermined breaking points 16 in the form of predetermined breaking lines are provided along the mutually perpendicular dimensions D1, D2. Furthermore, predetermined breaking points 17 in the form of predetermined breaking lines are provided between the frame 12 and the identification plates 10. This ensures that the identification plates 10, which are rectangular in shape here, can be easily broken out.

[0061] The identification plates 10 of the identification mat 1" according to Fig. 4 each comprise at least one, here two openings, by means of which the individual identification plates 10 can be attached to a (e.g. electrical) component.

[0062] In the examples shown, the marking mats 1, 1', 1" each have a plurality of marking plates 10. However, it is also possible for a marking mat 1, 1', 1" to be designed in the form of a single marking plate 10 and / or to have only one marking plate 10.

[0063] Fig. 5 shows the aforementioned printer 2, which can be used to label a marking mat 1. The printer 2 has a printing unit, which here is designed in the form of a laser 21, by means of which the marking mat 1 can be printed.

[0064] The printing unit can alternatively or additionally provide thermal transfer printing or inkjet printing. In one example, the laser 21 is designed as an infrared laser, in particular with a wavelength of 1064 nm.

[0065] During laser marking, a color and / or contrast change can be generated by laser radiation on the relevant surface, here the labeling surface 100 of the respective identification plate 10. This occurs through absorption of the laser energy by a material in the material of the labeling surface 100. The material of the marking mat 1 and thus of the identification plates 10 or the labeling surface 100 can, in particular, comprise a laser-sensitive additive in the form of a laser additive that can be activated by a laser (by absorbing the laser energy). The laser additive is designed to cause a particularly local and visible discoloration upon laser irradiation.

[0066] The laser additive is designed to absorb laser light and can be an organic compound or an inorganic compound. For example, the laser additive is a pigment, in particular a color pigment. Preferably, the laser additive is designed to absorb light in an absorption range with a wavelength between 400 and 1100 nm.

[0067] The laser additive(s) is / are particularly matched to the wavelength of the beam source used, in this case the laser. In other words, the laser additive is designed to absorb light in an absorption range that corresponds to the emission range of the laser. In one example, the laser is designed as an infrared laser, in particular with a wavelength of 1064 nm. Accordingly, in this example, the laser is designed to absorb light in the infrared range, in particular light with a wavelength of 1064 nm.

[0068] For example, the absorption ranges of the laser additive and the plastic differ from each other. Optionally, the absorption ranges of the laser additive and the plastic overlap at least partially.

[0069] The discoloration of the material at the points of laser irradiation can occur, for example, by darkening the corresponding plastic or the plastic composition in the material of the marking mat 1, in particular by burning plastics (carbonization) by laser irradiation. For this purpose, the material can contain, for example, titanium dioxide with a tin / antimony oxide coating as an additive.

[0070] With the help of the laser additive, it is possible to obtain defined and clearly visible labels or markings in a targeted manner (i.e. under defined laser irradiation).

[0071] The printer 2 has an opening 22. The opening 22 serves, in this case, for inserting the respective marking mat 1, 1', 1".

[0072] The printer 2 further comprises a holder 23, on which the marking mat 1 can be arranged and is arranged as shown in Fig. 5. In the example shown, the holder 23 is movable relative to a housing 20 of the printer 2. In the present case, the marking mat 1 arranged on the holder 23 can be displaced relative to the laser 21 by a relative movement of the holder 23 relative to the housing 20.

[0073] Fig. 6 shows a method for producing a marking mat (e.g., one of the marking mats 1, 1', 1" according to Figs. 1-4), in particular for marking electrical components, and for producing such a labeled marking mat. The method comprises the following steps.

[0074] In a first step S1, a material is provided. The material comprises a plastic or consists of a plastic. The plastic is produced in a step S10 by recycling, in particular chemical recycling, a thermoplastic, in a step S11 from a renewable raw material, and / or in a step S12 provided in the form of a biodegradable plastic. The chemical recycling of the thermoplastic in step S10 comprises, for example, solvolysis, depolymerization, pyrolysis, and / or gasification. To avoid repetition, reference is made here to the possible properties and compositions of the material described elsewhere herein.

[0075] In a further step S2, the marking mat 1, T, 1" is formed at least partially, in particular completely, from the material, for example by primary shaping, in particular by injection molding, and / or by forming. For forming, an injection mold can be provided, into which the material is introduced by plastic injection molding. The marking mat 1, T, 1" is then ready.

[0076] The material can comprise an additive which enables labelling, in particular printing, of the identification plates 10 by means of a laser, in particular an infrared laser.

[0077] In order to label the identification mat 1, the method further comprises a further step S3 in which at least the identification plates 10 of the identification mat are printed with a printer 2.

[0078] It should be noted that the process can be used to recycle a polymer by breaking it down into its original monomers or other, particularly petrochemically recyclable, materials through pyrolysis. Examples of such materials include methanol and synthesis gases. To obtain monomers, recycling can be carried out using a single-variety plastic. This makes it possible to recover not only monomers but also petrochemical raw materials. Furthermore, it is possible to extract gases, waxes, and oils of equivalent raw material value and correspondingly recyclable from, particularly mixed, plastic waste using degradative extrusion. This makes it possible to recycle even polymers that are difficult to separate.
