Description

The invention relates to a label carrier and a method for the same Manufacturing and application.

In particular in the automotive industry, but also in other industries, the plays Identification of individual components for their processing, especially in the case of mechanical ones Processing plays a big role. Here, the objects to be processed, for Example body parts or the like, provided with a label that Contains information about how the component in question is processed shall be. In most cases, type plates on the components are used for identification glued or riveted. For example, if you want to paint a body part, so the problem comes to light that the provided on the label Information inevitably disappears under the paint and therefore no longer are accessible. Especially in the automotive industry, where a component is often undergoes numerous painting processes, it becomes practically impossible to remember information under several layers of paint.

The aim of the invention is therefore to provide a label carrier which is based on can be attached to an object and allows on the Label provided information even after a or several processing steps, in particular painting processes or the like, to be able to access.  

According to the present invention, this object is achieved by a Labeling media with a base layer that can be labeled Information areas for receiving information, at least two Pieces of film removable on the base layer above the information areas are arranged. In this way, those located under the pieces of film Information, for example, a machine-readable manufacturing instruction may include when processing one with the label carrier marked object (for example during a painting process or the like) protected and then again by peeling off a piece of film be made accessible.

Under "foils" or "foil pieces" are here as in the following all types of Understand flat materials such as plastic films, nonwovens, fabrics, papers, etc.

It is envisaged that the slide pieces will be over one in an information area provided first information and one in the same or another Information area provided second information on the base layer are upset. Preferably at least part of the first and second Information identical. The common part can, for example, in coded form Instructions on the processing sequence (for example, type of paint to be applied) include. The "remaining" information can later be removed by removing a piece of film for example as component or manufacturer identification on the processed Object remain. The information areas can be a bar code or any have a different kind of information.

To ensure easier and, above all, safe removal of the film pieces is according to a further embodiment of the invention on at least one of the Foil pieces provided a grip tab. For example, it can be a Act shrink wrap, which after heating (during processing) forms a grip tab protruding from the rest of the label. Alternatively or in addition to this, at least one of the film pieces can also be made from a Shrink wrap exist. The film piece is then heated to remove it. If it then contracts, the edges of the piece of film arch upwards and form a suitable point of attack to remove the piece of film.  

Alternatively or in addition to this, the grip tab can be made of a non-adhesive Edge area of the film piece exist. Such a non-adhesive edge area can produced by selective application of adhesive with the exception of the edge area become. Likewise, a piece of film that is fully adhesive on its edge area with an adhesive cover or a means to remove the adhesive force be provided.

According to a further embodiment of the invention, the pieces of film are not applied overlapping on the base layer. This has the advantage that the Pieces of film can be formed in one piece. The separation can for example be over one or more lines of weakness, for example perforations, punchings or the like can be achieved. Individual pieces of film can then be along this Lines are detached from the label. For further material wear to contain, pieces of film and base layer can also be formed in one piece.

Depending on the application, at least one piece of film can be transparent. This is Particularly advantageous if the manufacturer or the user still Inscriptions made, for example, by laser or thermal transfer printing should be. Furthermore, the film pieces can be used as protective lacquer labels be trained.

According to a further advantageous embodiment of the invention, the Label carrier according to the invention on the side facing away from the film pieces the base layer is coated at least in sections with an adhesive. This Allows manual or automatic dispensing as preferably rolled goods assembled self-adhesive labels.

Furthermore, according to an advantageous embodiment of the invention, that a protective laminate is provided between the base layer and the film pieces is. The base layer and protective laminate can be formed in one piece. In order to can remove the information on the base layer before removing the pieces of film external, especially mechanical influences, are effectively protected.

According to a further advantageous embodiment of the invention is on the Label carrier provided an adhesion promoter. This can on the Protective laminate, on the side of the film pieces facing away from the base layer,  at least in sections on the base layer or on several of the above Positions may be provided. The adhesion promoter mediates particularly good liability between paint and the surface of the label. Will the Adhesion promoter covered with paint along with the label carrier and one or more of the pieces of film subsequently removed can be particularly smooth Breaklines are generated. Undesirable side effects, such as "lacquer flaking" in some places can be avoided in this way.

According to an advantageous variant, it is provided that the pieces of film are partially overlap. The overlapping areas can be used as grip tabs, for example be used.

In addition to this, the pieces of film can be cut into their edges Have security patterns. For example, it can be a coded one Act information or the like. When overpainting is then a Generated negative impression of this security pattern on the label, which becomes visible after removing the piece of film in question. Undesirable Attempts to manipulate can thus be made more difficult or prevented.

The invention also relates to a method for identifying an object the label described. The method has the following steps on: attaching the label to the object; Label the Label carrier on the base layer in the information areas; Perform a painting process by painting over with the Label provided object and removing at least one Pieces of film; and performing at least one further painting process and Removing at least one further piece of film. According to an advantageous variant the label is labeled before it is attached to the Object. A laser can be used for labeling. Alternatively, there is Possibility that the labeling is done by a thermal transfer printing process. According to a further advantageous variant, one is used in the further painting process Infrared-transmissive color used. This allows the information on Example with an infrared scanner or a similar reading device by the Paint layer can be made visible.  

The invention further relates to a method for producing a Labeling medium, which has the following steps: providing a first Material web and a second material web; Labeling the first web of material; Applying the second material web to the first material web for production a composite track; and production of the label by punching or Cutting out predetermined areas of the composite web.

The first and second material web can be formed in one piece. The The composite web can then be turned over by folding part of the material web onto the other Part.

According to an advantageous variant of the method, it is provided that the labeling the first material web takes place after the application of the second material web. The Labeling can be done, for example, using a laser or a laser Thermal transfer printing processes are carried out.

The label holder can be made using a stair-punching. The first and second material web are stacked by a special The punching tool provided is punched out of the composite sheet.

In addition, the composite web can at least on the side of the second material web be provided in sections with an adhesion promoter. For assembling the The adhesive layer can be used until the application of the Label holder be provided with a protective cover.

In Fig. 1A is an embodiment of the invention the marking carrier 1 is shown. The film pieces 3 a, 3 b are detachably connected to the base layer 2 . The film pieces 3 a, 3 b are preferably designed as labels. The film pieces 3 a, 3 b cover the areas of the base layer 2 provided with the information 4 a, 4 b, 5 . Part of the information 5 can contain, for example, a type designation or serial number. The other part of the information 4 a, 4 b contains, for example, instructions about the intended processing method (paint color, number of paint layers, etc.). This part of the information 4 a, 4 b can be found under each of the film pieces 3 a, 3 b, wherein the information can be either one part 4a or multiple parts 4b. The information 4 a, 4 b can be provided in the form of a machine-readable code (numbers or bar code). The information on an unpainted component equipped with a marking carrier 1 according to the invention is read by machine before the painting process. If necessary, a piece of film 3 b is first removed from the identification carrier 1 . This state is shown in FIG. 1B: by detaching a piece of film 3 b, an information area 6 has been exposed. Alternatively, there is the possibility of acquiring the information 4 a, 4 b through the film pieces 3 a, 3 b. For this purpose, the film pieces are preferably transparent. Whether transparent or opaque pieces of film are to be preferred depends on the specific application, in particular on the nature of the marked object and the point at which the marking medium is applied.

The component can be processed (painted) in accordance with the read information 4 a, 4 b. In Fig. 1C, an inventive identification carrier 1 is for a painting operation and after subsequent peeling of a film piece 3 a shown. The label carrier 1 is coated with a lacquer layer 8 . By removing a piece of film 3 a, an area is exposed 7 of the base layer 2, whereby the information 5, 4 a, 4 b can be made visible again. Characterized in that the film piece 3 a is shaped so that the edge of the base layer 2 remains uncovered, the marking carrier 1 is sealed at the edge by the coating 8 . This has the advantage that, on the one hand, the identification carrier 1 has a particularly good connection with the marked object and the liability of the identification carrier 1 cannot be affected by the influence of moisture or dirt particles. On the other hand, an undesired detachment and reapplication of the label carrier 1 by unauthorized third parties is thereby made impossible.

A label carrier according to the invention is shown in a side view in FIG. 2A. In this embodiment, the label carrier is designed as a self-adhesive label. An adhesive layer 9 is provided on the underside of the base layer 2 provided with the information 5 , 4 a, 4 b. This embodiment is particularly suitable for inexpensive, mechanical attachment to an object to be marked. An anti-adhesive siliconized carrier layer 10 can be provided for storage. In addition, the film pieces 3 a, 3 b can have grip tabs 12 for easier detachment, wherein grip tab 12 and a piece of film can be formed in one piece. Alternatively, it is also possible to attach the grip tab to the edge of the film piece using an adhesive (not shown). In addition, an adhesive dot (not shown) can fix the grip tab 12 on the piece of film. When the identification carrier is dispensed, this provisional, selective gluing is released, so that the grip tab 12 protrudes somewhat from the film piece on one side and thus offers a better point of attack, particularly after painting. In a further alternative, a shrink film can be used for the grip tab 12 . When the grip tab is heated, it contracts and bulges slightly. This also creates a better point of attack for later removal of the piece of film. So that the grip tab 12 does not lie flat on the film piece 3 a, 3 b, a spacer 16 can additionally be attached between the film piece 3 b and the grip tab. This has the effect that a curvature arises in the area of the grip tab 12 even when a lacquer layer is applied later, or that the grip tab 12 is even pressed through the lacquer layer.

Fig. 2B shows the aufgespendeten to an object 11 already processed marking carrier. In a previous work step, a piece of film 3 b has already been removed and then, according to the information 4 a, 4 b read, a lacquer layer 8 has been applied. In the area of the grip tab 12 on the film piece 3 a, a slight curvature has arisen in the lacquer layer 8 . At this point, the film piece 3 a can be easily gripped and removed with the aid of the grip tab 12 .

This situation is shown in Fig. 2C. By pulling on the grip tab, the film piece 3 a and the part of the lacquer layer 8 located above it are removed and the information 4 a, 4 b, 5 underneath become visible.

In Fig. 3, another embodiment of the invention is illustrated. In addition, a protective laminate 13 can be provided between the base layer 2 and the film pieces 3 a, 3 b. After the pieces of film have been removed, the marked components and thus also the identification carrier itself are generally exposed to external, in particular mechanical, influences. The protective laminate 13 protects the label and the inscription 5 , 4 a, 4 b from being destroyed. In addition, the label carrier can be provided with an adhesion promoter 14 at suitable locations. This adhesion promoter (so-called primer) ensures that the paint layer to be applied adheres particularly well where it is applied. The advantage of this is that when a piece of film is removed, the primer ensures that smooth break edges occur in the paint, and that the paint does not peel off when a piece of film is removed, where this is not desired.

To save material costs, the film pieces can be made in one piece. This is shown in Figure 4. The separation into individual film pieces 3 a, 3 b takes place only when they are removed along intended weakening lines 15, such as punchings or perforations. Pieces of film and protective laminate 13 can also be made in one piece. The film pieces 3 a, 3 b may also be configured so that they overlap, as shown in Fig. 5. In addition, the pieces of film can have a security pattern 17 cut into the edge. During production, this is punched into the sheet or pieces 3 a, 3 b or cut by means of a laser. For example, this can be encoded information such as a bar code or the like. When the painting is thereby a negative impression of this security pattern is generated 17 on the marking carrier 1, which is visible after removal of the relevant piece of film. Unwanted attempts at manipulation can thus be made more difficult or prevented.

To produce the marking carrier according to the invention, a material web that can be labeled is assembled with a second material web, which has the film pieces 3 a, 3 b and, moreover, optionally also the protective laminate 13 , to form a composite web. The information 4 a, 4 b, 5 can be labeled before the two material webs are connected or later. There is either the option of making the necessary markings by the manufacturer or leaving this to the later user. For example, the inscription can also be made through pieces of film (and protective laminate) using a laser or a thermal transfer printing process. The marking carriers produced in this way are cut out of the composite web or punched out by means of a stair punch.

As indicated in FIG. 5, the two material webs can be formed in one piece. The composite web is then produced by folding one wing of the material web 13 onto the other wing 2 . This procedure allows a particularly precise and exact positioning of the film pieces 3 a, 3 b above the information areas. As described above, this label holder can also be provided with information 4 a, 4 b, 5 by the manufacturer or user.

Another embodiment of the invention is shown in FIG. 6. The number of film pieces 3 a, 3 b, 3 c is not restricted to an upper limit, but can be varied depending on the application. In the example shown, the film pieces are attached on one side to the base layer 2 and overlap. The side attachment can be done, for example, with an adhesive. The overlapping areas can serve as grip tabs. As an alternative or in addition to this, there is the possibility of having the film pieces 3 a, 3 b, 3 c protrude beyond the edge of the identification carrier (not shown), which also creates points of attack for easier removal of one or more film pieces.
