Description

Technical field

[0001] The invention relates to a device for removing rolls, such as paper, film or textile rolls. State of the art

[0002] In the current state of the art, when removing rolls, especially large rolls, a common problem is that the rolled layers shift in a telescopic manner. This means that the individual layers of the roll can shift against each other and pull apart, leading to instability, damage, or difficulty handling the roll. This unwanted movement of the layers not only complicates the handling and transport of the rolls, but can also lead to material loss or quality degradation. This problem is particularly pronounced with heavy or large-format rolls, as their own weight and the lack of lateral support promote the telescopic displacement of the layers. Description of the invention: task, solution, advantages

[0003] The invention aims to provide a device that enables the safe removal of rolls while preventing the rolled-up layers from shifting.

[0004] The present invention relates to a device for removing rolls, which comprises a plate-shaped base body.

[0005] The device is designed to facilitate the removal of a roll, with the plate-shaped base body forming the central element. This is preferably made of a sturdy material and has a plate-like shape that provides sufficient support for the roll and reliably supports it during removal. "Plate-shaped" is understood to mean disc-shaped and / or plate-shaped, preferably with a constant height. The base body thus serves as the central support element and is preferably made of metal or plastic. Furthermore, the device can be made of a natural material, such as wood.

[0006] The base body can have various diameters to accommodate different roll sizes. Its height is selected to ensure stable handling without making the device unnecessarily bulky. The surface can be smooth or textured to prevent the roll from slipping during removal.

[0007] The device is particularly suitable for environments where rolls are regularly removed and transported. The special shape of the base body enables safe and efficient removal. It can be used as a roll removal aid, for example, for rolls of carrier material with labels. A roll is therefore preferably understood to be a rolled-up material, e.g., a carrier material that includes labels. The plate-shaped base body supports the roll during handling and prevents telescopic displacement.

[0008] In a preferred embodiment, the plate-shaped base body of the device has a first radius that emanates from a center point and defines at least one region of the base body. The radius determines the extent of this region and is recognizable in plan view as the distance from the center point to the outer boundary, i.e. the radial edge or end of the diameter. The first radius of the base body can be between 100 mm and 250 mm, particularly advantageously between 150 mm and 200 mm, with 170 mm to 190 mm being provided in a further preferred embodiment. The height, in other words, thickness, of the base body can be between 0.5 mm and 10 mm, preferably approximately 2.5 mm. These dimensions ensure sufficient stability without making the device unnecessarily heavy or unwieldy.

[0009] In a further embodiment, the plate-shaped base body of the device can have a first radius as well as a second radius, which also emanates from the center point. The second radius can differ from the first, so that the base body is not defined by a single, uniform radius. At least two different radii create areas with different dimensions on the base body, which enables the device to be adapted to different requirements when removing rolls and expands its functionality. For example, the base body can have at least two areas, each with dimensions determined by the associated radius. The second radius can, for example, be a maximum of 20 percent, preferably a maximum of 10 percent, smaller than the first radius.

[0010] In a further embodiment, the device can have an edge which preferably projects perpendicularly from the base body. This edge serves to additionally secure the roll arranged on the base body and to prevent it from slipping during removal. The edge can run along the circumference or in a radial end region of the base body and can be formed either completely around the entire circumference or only in sections. For example, the height of the edge can be between 5 mm and 50 mm. The material of the edge can be identical to that of the base body or different, for example more flexible, in order to enable the roll to be picked up gently. The edge can preferably be formed in one piece with the base body. The edge can comprise a recessed grip to facilitate removal of the roll. It is also possible for the edge to be formed only in certain sections in order to specifically support or guide areas of the roll.

[0011] The edge can be defined, at least in sections, by at least one radius that is between 100 mm and 300 mm, preferably between 150 mm and 250 mm. The center of the circle defining the edge can be offset from the center of the base body, in particular away from the edge, so that the edge can be indented relative to the radial end of the base body, at least in a central region. Two radii can also be provided, for example, a first in the central region and a larger second in the outer region, in order to specifically adapt the edge to different requirements and increase the functionality of the device.

[0012] In a further embodiment, the edge can extend over a maximum arc length of 180 degrees from the center of the base body. Such a partial configuration facilitates handling of the device when removing the roll, as it can be more easily picked up or removed from the open side, for example. The edge can be designed as a semicircle or any partial circular arc with a maximum arc length of 180 degrees. Alternatively, it can consist of several spaced-apart segments that together add up to 180 degrees.

[0013] In a further embodiment, the edge of the device can extend over at least 90 degrees, thereby covering at least a quarter circle of the circumference of the plate-shaped base body. This guides the roll arranged on the base body over a substantial area and secures it against slipping, while maintaining a sufficient opening for convenient removal or placement of the roll. The minimum arc length of 90 degrees can be formed by a continuous circular arc or by several adjacent segments that together make up the required length. Preferably, the minimum arc length of the edge is 120 degrees, which allows for even better guidance and securing of the roll without significantly complicating handling.

[0014] In a further advantageous embodiment, the edge of the device can have a height of 5 mm to 50 mm, with particularly favorable values ​​being between 5 mm and 40 mm. In certain cases, an edge height of 25 mm to 35 mm is particularly expedient. The edge height can remain constant along its length or vary in sections.

[0015] In a further embodiment, the plate-shaped base body of the device can have at least one recess extending continuously from an outer edge of the base body to an inner region of the base body. This recess can be designed, for example, as a slot-shaped, elongated opening. Thus, a carrier that encompasses the roll can be encompassed by the base body, thus accommodating the roll.

[0016] In a further embodiment, the recess arranged in the base body can run radially toward the center, i.e., along a line from the outer edge to the center of the base body. This radial alignment facilitates the adaptation of the device to different roll sizes and types. The radial recess can extend over part or the entire radius and reach the center or even extend beyond it. This makes the device flexible in use, for example, for removing rolls with different diameters or supports. Furthermore, the recess can reduce the weight of the device and facilitate handling.

[0017] In a further embodiment, it can be provided that the radially extending recess arranged in the base body has a radius at the inner end that relates to the center of this end. This radius is at least 10%, preferably at least 15%, of the radius of the base body. The center of the inner end region of the recess can be offset from the center of the base body, in particular towards the radial edge of the base body. It is possible for the center of the base body, the center of the edge, and the center of the inner end region to lie on a common straight line, with the center of the base body being in the middle.

[0018] The recess can extend from the inner end region with a constant width to the radial end of the base body. The width preferably corresponds to the diameter of the inner end region, creating a uniform, slot-like profile that simplifies handling and maintains stability.

[0019] Regarding the dimensioning of the radius at the inner end region, this can preferably be between 20 mm and 150 mm, preferably between 50 mm and 120 mm, and particularly preferably between 70 mm and 100 mm. This allows the device to be adapted to different roll sizes and weights without sacrificing functionality or stability.

[0020] In another possible embodiment, the edge of the device can be arranged at an opposite end of the base body compared to the radial end of the recess. This means that the edge is preferably located on the side of the plate-shaped base body opposite the radial end of the recess.

[0021] In a further possible embodiment, the edge of the device can have two ends, each of which is arranged in a radial end region of the plate-shaped base body. Between these two ends, the edge can be drawn in in an intermediate region relative to the radial end of the base body. This means that the edge does not run continuously along the outer circumference of the base body, but is positioned in a specific section closer to the center of the base body. This design allows the roll to be guided in a targeted manner during removal or placement and at the same time secured against slipping. The two ends of the edge can be arranged such that they each lie on opposite or adjacent regions of the circumference of the base body. The drawn-in region of the edge can in particular lie in the region between the two ends and extend in a radially inner direction.This creates a kind of recess or indentation that further facilitates the handling of the device and supports the insertion or removal of the roll.

[0022] The overall width of the device can be, for example, between 300 mm and 500 mm, preferably between 330 mm and 380 mm. These dimensions enable a stable yet handy design of the device, suitable for a variety of applications.

[0023] Furthermore, it can be provided that the second region of the base body, which is defined by a second radius, is divided into two by the recess. The first region of the base body, which is defined by the first radius, can in particular be formed as a continuous section. An intermediate region can be provided between the first and second regions, in which the base body is flattened. This design can contribute to increasing the stability of the device while simultaneously reducing its weight.

[0024] They show in a purely schematic representation: Fig. 1: a perspective view of a device for removing rolls; Fig. 2: a side view of the device according to Fig. 1; Fig. 3: a 90° rotated side view of the Fig. 2; and Fig. 4: a plan view of the device of the previous figures.

[0025] Fig. Figure 1 shows a perspective view of a device 10 for removing rolls. The plate-shaped base body 20 is clearly visible, as is the edge 40, which extends perpendicularly from the base body 20. Furthermore, the recess 30 is visible, which extends from an inner end region 32 to a radial end region 31. This is thus an open recess. The edge 40 comprises two ends 41, which are arranged at the radial end of the base body 20, and a central region 42. The central region 42 is indented toward a center point of the base body 20 opposite the radial end of the base body.

[0026] In Fig. Figure 2 shows a side view. The base body 20 and the edge 40 are again visible. The height 44 of the edge 40 is visible, as is the height 26 of the base body 20. Furthermore, a first width 27 of the base body 20 and thus also a width of the entire device 10 can be seen.

[0027] In Fig. Figure 3 shows a lateral view rotated by 90°, in which only the edge 40 and the base body 20 are visible. A second width 28 can be seen, which can essentially correspond to the first width 27 and preferably deviates from it by at most 40%, preferably at most 30%, most preferably at most 20%.

[0028] In Fig.Figure 4 shows a plan view of the device 10 of the previous figures. The base body 20 has a center point 21, from which a first radius 22 extends. The first radius 22 defines the dimensions of the base body 20 in a first region 23. The dimensions of this region are defined by the first radius 22. Starting from the center point 21, there is also a second radius 24, which defines the dimensions of the base body 20 in a second region 25. In contrast to the center point 21, the second region 25 is arranged at the opposite end of the base body 20 and can be divided into two by the recess 30. A central region, in which the edge of the base body can be flattened, can be arranged between the two regions.

[0029] The recess 30 can be defined in a radial end region 31 by a corresponding radius 34, starting from a center point 33. The recess 30 can extend from the inner end region 32 to a radial end region 31 with a continuous diameter 35. The diameter 35 corresponds in particular to twice the radius 34. It is thus an open recess, so that a carrier or core on which the roll has been clamped can be received in the recess 30.

[0030] The edge 40 can, in particular, have two ends 41, at which it attaches to the radial end of the base body 20. It extends, in particular, over an arc length starting from the center of the base body or from the center of the edge, which spans a maximum of 180°, but at least 90°, preferably at least 120°. In a central region 32, the edge 40 is indented relative to the radial end of the base body 20. The edge 40, in particular, has a center point 43, from which at least one radius 45 defines the edge. For example, a first radius 46 and a second radius 47 can be defined. The second radius 47 can be arranged in a region at the ends 41 and can be larger than the radius 46 for the central region 42.
