Description

[0001] The invention relates to a positioning system for positioning at least one embossing or creasing plate of an embossing and / or creasing device, as well as an embossing and / or creasing device for arc-shaped materials.

[0002] The use of embossing and creasing plates is an established process in many industries for embossing or creasing surfaces. Positioning wedges are often used in this context to correctly align the plates with each other during the production process.

[0003] However, there are disadvantages to using positioning wedges. One disadvantage is that positioning the embossing and creasing plates themselves can be difficult, which can lead to inaccuracies in alignment. Once the plates are positioned, it can be difficult to find the zero point again after positioning, which can affect the accuracy and repeatability of the process.

[0004] The use of positioning wedges is also manual, time-consuming, and expensive. Each wedge must be placed individually, which takes time and increases the risk of errors. Furthermore, positioning wedges can be costly, especially if they need to be made from special materials or if a large number of wedges are required.

[0005] Overall, the current alignment of embossing and creasing plates with positioning wedges is common, but offers room for improvement in terms of accuracy, repeatability, speed and cost.

[0006] The object of the present invention is to enable a faster alignment of a base plate and at least one embossing or creasing plate to each other, in order to achieve a correspondingly fast and accurate positioning of embossing and / or creasing elements of the embossing or creasing plate relative to a curved material to be processed in an embossing and / or creasing device.

[0007] This problem is solved according to the invention by a positioning system with the features listed in claim 1 and by an embossing and / or creasing device according to claim 11. Advantageous embodiments with expedient further developments are specified in the respective dependent claims, wherein advantageous embodiments of each aspect of the invention are to be regarded as advantageous embodiments of the other aspect of the invention.

[0008] A first aspect of the invention relates to a positioning system for at least one embossing and / or creasing plate of an embossing and / or creasing device. The positioning system comprises at least one base plate for arrangement on an embossing and / or creasing device, wherein the base plate has at least one mounting opening for a positioning element on its upper side; at least one embossing and / or creasing plate, which has at least one embossing and / or creasing element on its upper side and at least one mounting opening for the positioning element on its lower side; and at least one positioning element for aligning the base plate and the embossing and / or creasing plate relative to each other, wherein the positioning element has a first area for arrangement in the mounting opening of the base plate and a second area for arrangement in the mounting opening of the embossing and / or creasing plate.In other words, the invention relates to a system for positioning at least one embossing and / or creasing plate, comprising one or more base plates, one or more embossing and / or creasing plates, and one or more positioning elements. The base plate(s) and the embossing and / or creasing plate(s) each have at least one mounting opening into which an associated section of an associated positioning element can be inserted, the first section and the second section of the positioning element preferably being of different shapes. In this way, the base plate and the embossing and / or creasing plate can be positioned relative to each other by means of the positioning element. By selecting the appropriate positioning element, the relative positioning of the base plate and the embossing and / or creasing plate can be adjusted quickly and precisely.Terms such as "top," "bottom," "front," "bottom," "bottom," "horizontal," "vertical," "longitudinal direction," "lateral direction," "vertical direction," and the like refer to the position and orientation of the positioning system or the base plate and the embossing and / or creasing plate in its intended operating position relative to an observer standing in front of and looking at the positioning system. Each mounting opening can generally be configured as a through-hole or blind hole, independent of any other mounting opening. The positioning system can be used with all creasing and embossing plates and is suitable for all types of embossing and / or creasing devices. Furthermore, the embossing and / or creasing plate can also include a cutting or separating element for separating an arc-shaped material.The positioning elements can be manufactured from metallic and / or non-metallic materials, such as plastic, as required. Using positioning elements made of different materials offers additional flexibility in adjusting the positioning system for different applications and environmental conditions. In summary, the positioning system according to the invention offers numerous advantages over conventional systems. These include simple and precise positioning, the avoidance of time-consuming readjustments, the possibility of use in conjunction with various creasing and / or embossing methods, and increased efficiency through time and cost savings.The integration of the positioning system into an embossing and / or creasing device ensures precise and stable fixation of the plates to each other during the manufacturing process, thereby also increasing the quality of the manufactured products.

[0009] In an advantageous embodiment of the invention, the cross-section of the mounting opening of the base plate corresponds at least substantially to the cross-section of the first region of the positioning element, and / or the cross-section of the mounting opening of the embossing and / or creasing plate is larger than the cross-section of the second region of the positioning element. In other words, the mounting opening of the base plate is shaped to match the first region of the positioning element as precisely as possible. This ensures simple and reliable mounting and positioning of the first region of the positioning element on or in the base plate.Additionally or alternatively, the cross-section of the mounting opening for the embossing and / or creasing plate is larger than the cross-section of the second area of ​​the positioning element. This allows the embossing and / or creasing plate to move within the limits of the mounting opening relative to the positioning element. This design of the mounting opening as a kind of elongated hole is particularly advantageous when using multiple positioning elements, as the interaction of two or more positioning elements enables proper alignment and secure positioning of the embossing and / or creasing plate relative to the base plate. Because the larger dimensions of the mounting opening allow for some play in the connection, the embossing and / or creasing plate can still be easily placed onto the positioning element(s) and removed after use.

[0010] In a further advantageous embodiment of the invention, the base plate and the embossing and / or creasing plate each have two mounting openings for relative alignment of the base plate and the embossing and / or creasing plate in a first direction relative to each other, and two mounting openings each for relative alignment of the base plate and the embossing and / or creasing plate in a second direction relative to each other, wherein the first and the second directions are preferably arranged perpendicular to each other. The use of two mounting openings for each spatial direction in the plane (xy-plane) enables stable and precise positioning of the base plate and the embossing and / or creasing plates. The preferably perpendicular arrangement of the first and second directions ensures that the plates are always aligned at right angles to each other. Furthermore, relative rotation of the plates relative to each other is prevented.This inventive design enables particularly simple and precise positioning of the embossing and creasing plate(s). It also solves the problem of the difficult task of relocating the zero point after positioning. Furthermore, the positioning system is more cost-effective and time-saving than conventional methods.

[0011] In a further embodiment, it has proven advantageous to arrange two mounting openings of the base plate and the embossing and / or creasing plate on opposite sides of each other, and / or to arrange two mounting openings of the base plate and the embossing and / or creasing plate on diagonally opposite corners of each. In other words, the positioning system is designed to have two mounting openings per side or two mounting openings per diagonally opposite corner of the base plate and the embossing and / or creasing plate. This arrangement offers numerous technical advantages.The use of corresponding, opposing mounting openings in the middle section of the long sides of the plates, as well as corresponding, diagonally opposite mounting openings in the corner sections of the plates, allows for precise and easy positioning of the embossing and / or creasing plates in the xy-plane relative to the base plate. Furthermore, this arrangement ensures secure fixing of the plates in a right-angled position, meaning that no relative rotation is possible.

[0012] In a further advantageous embodiment of the invention, the first region of the positioning element has a non-circular cross-section, in particular a cuboid shape, and the second region of the positioning element has a non-circular cross-section, in particular a cuboid shape and preferably a cube shape, wherein the cross-sectional area of ​​the second region is larger than the cross-sectional area of ​​the first region. In other words, the positioning element has a non-circular and preferably cuboid shape for the first region and a non-circular, preferably cuboid and particularly preferably a cube shape for the second region, wherein the cross-sectional area of ​​the second region is larger than the cross-sectional area of ​​the first region. Such a non-circular design enables the positioning element to be secured against rotation within the associated mounting opening.Furthermore, the positioning system can be designed according to the "poka-yoke" or "failproof" principle, so that the positioning element can only be inserted into the respective mounting opening in one permissible orientation. Since the second area of ​​the positioning element, which corresponds to the embossing and / or creasing plate, has a larger cross-sectional area than the first area, it is also ensured that the insertion direction of the positioning element is immediately recognizable, that the positioning element can only be inserted into the base plate in the correct orientation, and that the second area forms a kind of stop when the first area is inserted into the corresponding mounting opening of the base plate, limiting the movement of the positioning element into the mounting opening.

[0013] Further advantages arise from the fact that the height of the first section is between 5 mm and 10 mm, particularly approximately 8 mm, and / or that the height of the second section is between 1 mm and 5 mm, particularly approximately 3 mm, and / or that the width of the first section is between 1 mm and 3 mm, particularly approximately 2 mm, and / or that the width of the second section is between 2 mm and 4 mm, particularly approximately 3 mm. This ensures, on the one hand, good handling of the positioning element during production, and on the other hand, that the positioning element possesses the necessary stability to enable secure positioning of the plates. Furthermore, different positioning elements can be provided by using different dimensions within the aforementioned limits to achieve different relative orientations between the plates.The respective width of the two areas is preferably chosen so that it provides sufficient support in the associated mounting opening on the one hand and allows for easy insertion and removal on the other.

[0014] In a further advantageous embodiment of the invention, it is provided that, in a longitudinal projection of the positioning element, a side wall of the second region has a distance from a side wall of the first region and a distance of approximately 1.0 mm to 3.0 mm from a central axis of the first region. In other words, it is provided that a side or outer wall of the second region projects beyond a side or outer wall of the first region in at least one direction in longitudinal section, wherein the side or outer wall of the second region additionally has a distance from a central or longitudinal axis of the first region, this distance being between 1.0 mm and 3.0 mm. For example, the distance can be 1.0 mm, 1.5 mm, 1.8 mm, 2.0 mm, 2.05 mm, 2.5 mm, etc.This allows for the provision of a positioning element by means of which the base plate and the embossing and / or creasing plate can be positioned relative to each other by a predefined distance, with the side or outer wall of the second area forming a stop for a corresponding wall of a receiving opening for the embossing and / or creasing plate. This prevents the embossing and / or creasing plate from not being moved far enough or from being moved too far, thus preventing an undesired result.

[0015] Further advantages arise from the provision of several differently designed classes of positioning elements, which are interchangeable to allow for different relative orientations of the base plate and the embossing and / or creasing plate. This allows the correct positioning element for each specific application to be easily selected from a group of different classes to achieve various relative orientations between the base plate and the embossing and / or creasing plate. The individual classes differ primarily in their geometry, but may also exhibit other distinguishing features.

[0016] Further advantages arise from the fact that, depending on the positioning element class, the relative arrangement of the central axis of the first area and the central axis of the second area differ. In other words, depending on the respective positioning element class, the relative position of the first and second areas of a positioning element differs from each other in order to achieve correspondingly different relative positioning of the plates. In certain embodiments, the geometry of the first and second areas themselves can be independent of the class, with only the relative positioning of the first and second areas varying according to the class. Alternatively or additionally, each class is provided with a marking that characterizes the respective class.For example, each class can have a marker that indicates to the user the displacement distance achieved with the corresponding positioning element, thus facilitating the selection of the positioning element. The marker could be, for example, a color code or color marking applied to at least one surface or side of the positioning element. Of course, other markers are also conceivable, such as shapes, engravings, raised areas, imprints, etc.

[0017] In a further advantageous embodiment of the invention, the base plate and the embossing and / or creasing plate have at least substantially the same cross-sectional areas. This allows for easy pairing of a base plate with an embossing and / or creasing plate. Several pairs of base plates and embossing and / or creasing plates can then optionally be combined or assembled into an ensemble for an embossing and / or creasing device, wherein, in particular, the individual embossing and / or creasing plates can be identical or differ from one another in order to produce locally different embossing and / or creasing patterns. Alternatively or additionally, the base plate is provided to have a greater thickness than the embossing and / or creasing plate.This allows for a sufficiently deep mounting opening and the insertion of at least one positioning element deeper into the base plate to withstand higher forces. Alternatively or additionally, the base plate and the embossing and / or creasing plate are designed to be the same length. This ensures good and uniform force transmission from the embossing and / or creasing plate across the entire length of the base plate.

[0018] A second aspect of the invention relates to an embossing and / or creasing device for embossing and / or creasing arc-shaped materials, comprising at least one positioning system according to the first aspect of the invention. This enables correspondingly fast and precise positioning of one or more embossing and / or creasing plates relative to one or more associated base plates and thus relative to an arc-shaped material to be processed within the embossing and / or creasing device. Further resulting features and their advantages can be found in the descriptions of the first aspect of the invention. Generally, "one" or "a" within the context of this disclosure is to be read as an indefinite article, i.e., unless expressly stated otherwise, always also as "at least one" or "at least one". Conversely, "one" or "a" can also be understood as "only one" or "only one".

[0019] In an advantageous embodiment of the invention, the embossing and / or creasing device has several positioning systems, wherein the base plates are arranged in a grid pattern and each associated embossing and / or creasing plate is aligned relative to the respective associated base plate by means of at least one positioning element.

[0020] In an advantageous embodiment of the invention, the embossing and / or creasing device comprises several positioning systems, wherein the base plates are arranged in a grid pattern and each associated embossing and / or creasing plate is aligned relative to its respective associated base plate by means of at least one positioning element. In other words, the embossing and / or creasing device has several positioning systems in which the base plates are arranged in a grid pattern, with each embossing and / or creasing plate being aligned relative to its respective associated base plate by at least one positioning element, so that the desired embossing and / or creasing pattern is produced in the arc-shaped material.The arc-shaped material is preferably made of a cellulose-based material, such as paper, cardboard, or kraft paper, but it can also be made of plastic, metal, composite material, or the like. This arrangement solves the problems associated with positioning embossing and creasing plates, particularly the difficulty of finding the zero point after positioning. The use of conventional positioning wedges is no longer necessary, saving time and money. The base plates are arranged in a grid pattern to ensure simple and precise positioning.

[0021] Further features of the invention are evident from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations without departing from the scope of the invention. Thus, embodiments that are not explicitly shown and explained in the figures, but which can be derived and generated from the explained embodiments by separate combinations of features, are also to be considered as encompassed and disclosed by the invention. Embodiments and combinations of features that do not exhibit all the features of an originally formulated independent claim are also to be considered disclosed.Furthermore, embodiments and combinations of features, in particular those set out above, are to be considered disclosed which go beyond or deviate from the combinations of features set out in the cross-references of the claims. This shows: Fig. 1 a perspective view of an embossing and / or creasing device; Fig. 2 a transparent exploded view of a positioning system according to the invention; Fig. 3 a transparent side view of the positioning system according to the invention; Fig. 4 a transparent front view of the positioning system according to the invention; Fig. 5 a transparent overhead view of the positioning system according to the invention; and Fig. Six side views of three different classes of a positioning element.

[0022] Fig. Figure 1 shows a perspective view of an embossing and / or creasing device 10 according to the invention for embossing, creasing, or cutting sheet-shaped materials (not shown), such as cardboard. The embossing and / or creasing device 10 comprises several positioning systems 12 according to the invention, which are arranged in a grid pattern.

[0023] Fig. Figure 2 shows a transparent exploded view of one of the positioning systems 12 according to a preferred embodiment. It can be seen that the positioning system 12 has a base plate 14, which is inserted into the embossing and / or creasing device 10 and secured in position. The base plate 14 has, by way of example, four mounting openings 16 on its upper surface 14a for respective positioning elements 18. Furthermore, the positioning system 12 has an embossing and / or creasing plate 20, which has one or more embossing, creasing, or cutting elements 24 on its upper surface 20a (see Figure 2). Fig. 1) possesses, which for the sake of clarity in Fig. 2 are not shown. On its underside 20b, the embossing and / or creasing plate 20 has, by way of example, four mounting openings 22 for the positioning elements 18, wherein the mounting openings 22 are aligned with the mounting openings 16 at least in certain relative orientations of the base plate 14 and the embossing and / or creasing plate 20. The four positioning elements 18 shown here serve to align the base plate 14 and the embossing and / or creasing plate 20 relative to each other, wherein each positioning element 18 has a first area 18a (see Figure 2). Fig. 6) for arrangement in the associated mounting opening 16 of the base plate 14 and a second area 18b (see Fig. 6) for arrangement in the corresponding mounting opening 22 of the embossing and / or creasing plate 20.

[0024] In the present embodiment, the mounting openings 16 in the base plate 14 are designed as through holes or openings and extend between the top 14a and the bottom 14b (see figure). Fig. 3) of the base plate 14, while the mounting openings 22 are merely designed as recesses or blind holes. In other embodiments, however, the respective design of the mounting openings 16, 22 may differ. It can also be seen that two mounting openings 16, 22 are arranged on opposite sides of the base plate 14 and the embossing and / or creasing plate 20, i.e., in the middle and at the edge of the respective longitudinal side, and that two mounting openings 16, 22 of the base plate 14 and the embossing and / or creasing plate 20 are arranged at diagonally opposite corner regions of the base plate 14 and the embossing and / or creasing plate 20. This allows for a defined relative movement between the base plate 14 and the embossing and / or creasing plate 20 in the xy-plane via the selection of the positioning elements 18 described in more detail below.The positioning is therefore always perpendicular, as rotation is not possible. The four mounting openings 16, 22 in the centers of the respective long sides of the base plate 14 and the embossing and / or creasing plate 20 are responsible for the relative positioning in the x-direction, while the four diagonally opposite mounting openings 16, 22 in the corner areas of the base plate 14 and the embossing and / or creasing plate 20 are responsible for the relative positioning in the y-direction. By selecting appropriate positioning elements 18 from different classes, the embossing and / or creasing plate 20 can be offset relative to the base plate 14 without displacement.

[0025] Fig. Figure 3 shows a transparent side view of the positioning system 12 according to the invention. It can be seen that the base plate 14 and the embossing and / or creasing plate 20 have the same length (80 mm) in the example shown, whereas the creasing plate 20, with a height of 8 mm, is thicker than the embossing and / or creasing plate 20, which has a height of 6 mm. Furthermore, the positions of the positioning elements 18 in the installed state within the respective mounting openings 16, 22 can be seen.

[0026] Fig. Figure 4 shows a transparent front view of the positioning system 12 according to the invention, while Fig. Figure 5 shows a transparent top view of the positioning system 12 according to the invention, wherein the positioning elements 18 are in Fig. Figure 5 is not shown for clarity. It can be seen that the base plate 14 and the embossing and / or creasing plate 20 each have an exemplary width of 40 mm. Fig. Figure 5 further shows that the mounting openings 16 of the base plate 14 have a round cross-section, while the mounting openings 22 of the embossing and / or creasing plate 20 are cuboid, i.e., rectangular in cross-section. This allows the positioning elements 18 in the mounting openings 16 of the base plate 14 to generally rotate about the central axis Ma of their first section 18a, but they are secured against rotation relative to the embossing and / or creasing plate 20 in the mounting openings 22. In this way, minor tolerances can be easily compensated for. Alternatively, it can also be provided that the positioning elements 18 in the base plate 14 are secured against rotation by a correspondingly non-circular cross-sectional geometry of the mounting openings 16 and the first sections 18a.The cross-sections of the mounting openings 22 are generally larger than the cross-sections of the associated second areas 18b of the positioning elements 18, thereby achieving a corresponding freedom of movement of the embossing and / or grooving plate 20 within the limits set by the mounting openings 22 and the positioning elements 18 relative to the base plate 14.

[0027] Fig.Figure 6 shows side views or longitudinal projections of three different classes of the positioning element 18. From left to right, the positioning elements 18 differ by a relative, axial offset A of the central axis Ma of the first region 18a compared to the central axis Mb of the second region 18b. In the left example, the axial offset A = 0, meaning that the central axes Ma and Mb are coaxially arranged. The axial offset A then increases from the middle to the right example. In other words, the first region 18a and the second region 18b are essentially identical, but shifted relative to each other in one direction depending on the class. The first region 18a is cuboid in this case and has a length / height of 8 mm and a width of 1.9 mm, or, in the case of an alternative circular cylindrical design, a diameter of 1.9 mm.In contrast, the second area 18b is cube-shaped and has a side length of 3 mm. Thus, in the left example, one side face of the second area 18b is 1.5 mm away from the central axis Ma of the first area 18a. Furthermore, in longitudinal projection, the second area 18b projects 0.55 mm beyond the respective side wall of the cuboid first area 18a on all four sides. The side face of the second area 18b forms a bearing surface for a wall of its associated mounting opening 22. In the middle example, the central axis Mb of the second area 18b is shifted by a distance A relative to the central axis Ma, resulting in the side wall of the second area 18b being 1.8 mm away from the central axis Ma of the first area.By selecting this class shown in the middle, a relative offset of 0.3 mm in one direction can be created between the base plate 14 and the embossing and / or creasing plate 20 compared to the first class shown on the left. In the class shown on the right, the distance between the side wall of the second area 18b and the central axis Ma of the first area 18a is then 2.05 mm, which allows for a correspondingly larger relative offset between the base plate 14 and the embossing and / or creasing plate 20. The individual classes can be distinguished, for example, by different colors, so that a user can quickly and easily select the positioning elements 18 required for correct alignment.By combining the four pairs of mounting openings 16, 22 and selecting the appropriate positioning elements 18 from the required classes, precise relative positions in the x and y directions can be achieved. It should be noted that the dimensions shown for the individual plates 14, 20, the mounting openings 16, 22, and the positioning elements 18 are purely exemplary and can be designed differently depending on requirements. Likewise, the number and arrangement of the mounting openings 16, 22 can vary.
