    Description [0001] The invention relates to a square timber for stacking products.
    Squared timbers are commonly used for stacking products. The squared lumber may be arranged between a floor and the product or between two stacked products. In contrast to an intermediate layer or intermediate layer, the square timber is much longer than it is wide. The squared timber, in contrast to the size of the product, represents a small contact surface. As a result, a squared timber must be designed for a relatively large surface pressure.
    It is an object of the present invention to provide a squared timber for stacking products that is extremely lightweight construction and stable to external influences with a stable structure. Furthermore, the square timber should be easy and inexpensive to produce.
    The object is achieved by the protection claim 1. The dependent claims have preferred developments of the invention to the subject.
    Thus, the object is achieved by a squared timber for stacking products, comprising two spaced cover plates. Between the two cover plates, a honeycomb layer is arranged. The two cover plates consist of a wood material, plastic or composite material. The honeycomb layer is made of paper. Furthermore, at least one web is arranged between the two cover plates. The bridge is also made of wood-based material, plastic or composite material. The term wood material also includes pure wood. In the context of the invention, the plastics also include fiber-reinforced plastics, in particular glass fiber-reinforced plastics. The composite material comprises in particular wood-plastic composites.
    The honeycomb layer of paper can be made very cheap and is extremely lightweight. The term "paper" is also a cardboard or cardboard material to subsume. The wood material, the plastic or the composite material for the cover plates and for the webs has the decisive advantage that it is much more stable and resistant than the paper. For example, the wood-based material remains resilient and dimensionally stable when exposed to moisture on the square timber. Furthermore, the wood material of the cover plates can be adapted very well to the respective fields of application of the square timber.
    It is preferably provided that in a cover plate at least one recess, in particular a groove, is milled. This recess is formed and used according to the products to be stacked.
    The at least one web helps to absorb point loads that occur, for example, in packaging lines or conveyor chains.
    The cover plates and the at least one web give the timber a relatively stable surface, so that the squared timber can be used well in automatic packaging equipment. Due to the very light construction of the square timber, the same can also be used well for the hand rest.
    It is preferably provided that the honeycomb layer has a plurality of individual honeycombs. Each of these honeycombs forms a cavity. The honeycombs are formed by side walls of the honeycomb layer. These side walls are made of paper and are glued together. The side walls are preferably arranged perpendicular to the cover plates. The cover plates serve as support surfaces for the products to be stacked. Accordingly, the squared timber is loaded perpendicular to the cover plates.
    Furthermore, it is preferably provided that the entire space between the two cover plates is filled by the honeycomb layer and the at least one web. The webs can divide the space between the two cover plates. Accordingly, the honeycomb layer is divided into several individual parts. Preferably, the two cover plates are the same size and are congruent to each other. In order to achieve a corresponding load capacity of the square timber over the entire surface, the entire space between the two cover plates is preferably filled by the honeycomb layer and the at least one web.
    The square timber has two end faces. The end faces are also referred to as end grain. Preferably located on at least one end face, particularly preferably on both end faces, one of the webs. In particular, it is provided that the web on the front side completely closes the space between the two pressure plates. When stacked products are lifted, for example with a forklift, the fork of the forklift moves between the two products. The two products are spaced apart by the squared timbers. When lifting the products by the stacker, there is always a small imbalance of the product and thus an uneven loading of squared timbers. In order to avoid a destruction of the squared timbers and tipping the stacked products, the frontal webs are preferably used.
    Furthermore, at least one web is preferably provided between the two end faces of the square timber. This one bar is particularly preferably in the middle. If a plurality of webs are arranged, they are preferably distributed uniformly or asymmetrically. The webs are used in particular for recording point loads.
    The paper of the honeycomb layer is preferably water-repellent. In particular, it is provided that the paper is water-resistant. Furthermore, it is preferably provided that the paper of the honeycomb layer is fire-resistant. For the water-repellent and / or fire-resistant embodiment, the paper of the honeycomb layer is preferably impregnated and / or coated.
    Preferably, it is provided that the paper of the honeycomb layer has a Cobb60 value according to DIN EN 20535 or ISO 535 of not more than 40 g / m 2, preferably not more than 35 g / m 2, particularly preferably not more than 32 g / m 2.
    The mesh size of the honeycomb layer used is preferably between 5mm and 70mm, more preferably between 20mm and 50mm. The preferred areal density of the honeycomb layer is between 80g / m2 and 600g / m2. The preferred thickness of the honeycomb layer is between 4mm and 150mm, preferably between 10mm and 150mm.
    The honeycomb layer and / or the webs are preferably glued to the two cover plates. In the manufacturing process, a plate is first designed that is much larger than the single cover plate. On this plate, a plurality of webs and the honeycomb layer, for example, from an endless roll, positioned. Then a second plate is glued on top. After setting the adhesive, the sandwich-type construction is cut into individual squared timbers.
    The square timber extends over a length, a width and a height. The two cover plates have in particular the length and the width. The product of the length and the width accordingly gives the support surface.
    The length is preferably much larger than the width. In particular, it is provided that the length is at least four times, in particular six times, particularly preferably eight times, the width. In particular, the squared timber is between 3 cm and 30 cm wide.
    The at least one web preferably extends over the entire width of the square timber, so that over the entire width a support of point loads is possible.
    In order to achieve the simplest possible construction of the square timber, it is preferably provided that as much as possible of the intermediate space is occupied by the honeycomb layer. At the webs, a bridge length is defined. The bridge length is measured in the longitudinal direction of the square timber. In a preferred embodiment, it is provided that the sum of the web lengths of all webs used is at most 35%, preferably at most 25%, particularly preferably at most 20%, of the length of the square timber. Furthermore, it is advantageous for the lightweight structure of the square timber that the cover plates are relatively thin compared to the honeycomb layer. Accordingly, it is preferably provided that a plate thickness of the individual cover plate is a maximum of 25%, preferably not more than 20%, particularly preferably not more than 15%, of the height of the square timber.
    In the following the invention will be explained in more detail with reference to embodiments. FIG. 1 shows a sectional view of a squared timber according to the invention in accordance with a first. FIG
    1 is a plan view of a honeycomb layer of the squared timber according to the first embodiment; and [0027] FIG. 4 is a plan view of one Honeycomb layer of the squared timber according to the invention according to a second embodiment.
    In the following two embodiments of the timber timber 1 will be described. The same or functionally identical components are provided with the same reference numerals.
    Fig. 1 shows a section A-A by a square timber 1. The course of the section A-A is shown in Fig. 2. Fig. 2 shows the top view of the timber 1.
    The square timber 1 comprises two spaced-apart cover plates 2. The two cover plates 2 are each the same size and the same thickness and congruent arranged one above the other. Between the two cover plates 2 are a honeycomb layer 4 and three webs 3. The two cover plates 2 are each directly on the webs 3 and the honeycomb layer 4 on or on.
    The square timber 1 has two opposite end faces 13. The two cover plates 2 form bearing surfaces 14 for products to be stacked.
    The square timber 1 extends over a length 5, measured in the longitudinal direction, and a width 6. Furthermore, the square timber 1 has a height 7.
    The webs 3 extend over a web length 10. The web length 10 of the individual webs 3 is relatively small, so that a large part of the gap between the two cover plates 2 is occupied by the honeycomb layer 4. As the dashed lines in Fig. 2 show, the webs 3 extend over the entire width 6 of the square timber. 1
    The two cover plates 2 have a plate thickness 8. The honeycomb layer 4 has a layer thickness 9. The plate thickness 8 is much smaller than the layer thickness 9, so that a leichtbauender structure of the square timber 1 is formed.
    Preferably, the timber 1 is open at the side, so that the honeycomb layer 4 is visible. The timber 1 thus preferably consists exclusively of the two cover plates 2, webs 3, and honeycomb layers. 4
    FIG. 3 shows a plan view of the honeycomb layer 4. Only a section of the honeycomb layer 4 is shown. Fig. 3 shows the same perspective, namely a plan view, as shown in FIG. 2. The honeycomb layer 4 is composed of individual honeycomb 11, each forming a cavity. The honeycomb 11 are formed by side walls 12 which are glued together. In FIG. 3, the honeycomb layer 4 has a plurality of side walls 12 arranged parallel to one another. Between these side walls 12 sinusoidal side walls 12 are used.
    Fig. 4 shows according to a second embodiment, an alternative embodiment of the honeycomb layer 4. In Fig. 4, each side wall 12 of the honeycomb layer 4 is formed bent. Again, the side walls 12 are glued together, so that corresponding cavities arise. In both embodiments, the side walls 12 of the honeycomb layers 4 are perpendicular to the cover plates 2, so that the corresponding loads on the bearing surfaces 14 can be accommodated.
    The honeycomb layer 4 is made of paper and a small amount of adhesive to bond the individual side walls 12 together.
    The cover plates 2 and the webs 3 are made of a wood material, in particular of chipboard, MDF wood panels, HDF wood panels or plywood panels. 4.7
