Abstract

The invention relates to stacks of panels (1), in particular, laminated panels, packaged for transport or storage. Said stack comprises several coated panels, for example, laminated panels, panels made from plywood, fibreboard or wood panels. The stack further comprises a packaging, with at least one strap (3), going around the stack and/or at least one retainer element (2), on the front side of the stack for fixing the panels. For example, the strap or the retainer element are provided in addition to further packaging elements, such as shrink-wrap or cardboard completely or partly enclosing the panels. The retainer element can, for example, be fixed to the stack and enclose the front face of the stack. By means of both measures, either individually or in combination, the withdrawal and removal of single panels from the stack is hindered or prevented. For example the strap can run perpendicular to the longitudinal direction of the panels. The strap can also be of elastic embodiment and applied such as to hold the individual panels tight. In a further embodiment, the strap lies so tightly on the stack that on withdrawing a panel, in particular, the outer panel, said strap is tipped in the longitudinal direction of the stack and thus tightens preventing a further withdrawal. By arrangement of the strap perpendicular to the longitudinal direction of the stack, the possibility of stacking several stacks on top of each other is not affected.

Description

Description: The present invention relates to stacks of panels, in particular laminate panels, packed for transport or storage. Laminate panels are generally packed in layered stacks of, for example, 4 to 10 pieces of panels each. The stacks are generally shrink-wrapped in transparent film and / or wrapped in specially formed or folded paperboard. The films are, for example, shrink films based on polyethylene, polyvinyl chloride, or polyethylene terephthalate. The packaging or films are produced in accordance with the Packaging Ordinance in such a way that the volume and mass are limited to the amount which is directly necessary. The package or film has the disadvantage that it can be easily torn by hand or a sharp object to remove individual panels, this may for example be the case in a hardware store.

The takeaway goods issued in the hardware store are regularly opened by the customers in order to partially or completely pull out individual panels, for example in order to better evaluate the surface design of the packaging

Sharp edge of the panels the film at the outer ends are punctually overloaded and tearing, These, especially the outside in the packaging panels, can be behind only laboriously or not bring back into the package, Due to the generally existing with buyers skepticism towards open Sales packages regarding the Conditions and the quality of the goods, the open piles are generally difficult to sell,

Against the background of the disadvantages described above, it is therefore an object of the present invention to provide a stack of panels which is improved with respect to the packaging.

This object is achieved by a generic device with the features of claim 1, Advantageous embodiments will become apparent from the dependent claims,

The stack according to the invention consists of several layered panels. For example, these are laminate panels, plywood panels, fiberboard panels or wood panels. The stack further comprises a package. Means are also provided for removing the panels from the package. For example, these damage can be caused by mechanical effects on the packaging, for example, these mechanical stresses arise during transport of the stack or by intentional exposure to the package with a sharp object. In a further embodiment, the means against removal of the panels additionally restrict the freedom of movement of the panels in the stack and thus provide additional protection against the removal of individual panels from the packaging in comparison to conventional packages. This advantageously makes it possible to extract and remove individual panels from the stack makes it difficult or impossible. According to a further advantageous embodiment, the means for removing the panels advantageously comprise a band around the Stack. Through the band, the panels are fixed together. A removal in the direction of the belt is not possible or only after cutting the tape. In addition, a plurality of bands may be provided, in one embodiment, the bands comprise the stack in the longitudinal and transverse directions to secure the stack in all directions against pulling out of individual panels. The tape consists for example of paper, polyethylene, polypropylene or polyethylene terephthalate. The band can be printed in one embodiment to additionally act as an advertising medium. Its comparatively firm fixation on the stack ensures that the information provided on the tape is not lost or the advertising effect is not lost.

In an advantageous embodiment of the invention, the band runs transversely to the longitudinal direction of the panels. It has been shown that thereby a displacement of the panels is prevented transversely to the strip so in the longitudinal direction of the panels to a sufficient extent and additional bands in the longitudinal direction can advantageously be eliminated. For example, the band is elastic, consists for example of stretch film and is designed so that it holds the individual panels by clamping, in a further embodiment, the tape is so close to the stack, that when pulling out a panel, in particular the outer panels, in Due to the arrangement of the tape transversely to the longitudinal direction of the stack, the stackability of several stacks on each other is not adversely affected by the longitudinal direction of the stack and thus clamping prevents further withdrawal. For example, has a narrow compared to the stack, longitudinally extending single band the disadvantage that due to the strength of the tape, the stack does not lie flat on each other and thus several stacks unstable d .h, not flat lie on each other, which ultimately the maximum pile height negative affected The latter is particularly in Bαumärkten of particular disadvantage, since the audience must not be endangered on the one hand, on the other hand, space is precious. Moreover, with this arrangement, the band is comparatively short, which is advantageous in view of the above-mentioned packaging ordinance and the general requirement to reduce the amount of packaging material contained therein.

In a further advantageous embodiment, the band is arranged spaced from one side of the panel, This prevents the tape from slipping off the stack, especially when the panels are moved against each other during transport, It has been shown that a distance of more than 5cm between tape and side of the panel or, the stack at the usual mechanical stresses to which the stack is exposed, for example, during transport, sufficient to ensure slippage of the tape from the stack sufficiently, through experiments has been found that this ensures that the For example, if a panel is pulled out along the stack towards the other end of the stack, the panel sections remaining behind the band in the reverse direction are sufficient to prevent jamming or pinching of the band Another one ilhafte embodiment of the stack according to the invention provides that the band consists of polyvinyl chloride, Thus, the band can be produced comparatively inexpensive.

In a further embodiment, the band is advantageously made of shrink film. These are cold-stretched, thermoplastic materials that undergo heat treatment This shrinking ensures that the tape sits firmly on the stack after cooling to hold the panels clamped.

According to a further embodiment, the tape has a width of at least 2 cm, tests have shown that thereby a clamping holding the tapes is ensured, on the other hand, the amount of packaging material in the sense of the Packaging Ordinance is not unnecessarily increased,

A further embodiment provides that the band is substantially transparent. For example, the band has transparent portions or is completely transparent. Thus, for example, the surface of the panel can be inspected despite the band or product descriptions or installation instructions arranged between band and panels can be studied.

According to a further advantageous embodiment, the means against removal of the panels advantageously comprise at least one attached to one side of the stack holding element, By the holding element, a displacement of the panels is avoided against each other, the holding element can, for example, on the

Be attached packaging, for example, in a packaging film with welded. The holding element can be provided alone and in combination with the previously described bands. In one embodiment, the holding element is attached to the respective narrow sides of the stack and parallel to the narrow sides run two bands comprising the stack. By such a design of the means against removal can Amount of material required to secure the panels is advantageously kept low, According to a further embodiment, the holding element made of cardboard, in particular corrugated board, for example, the holding element is formed in a the front side of the stack enclosing cover made of cardboard, the cardboard thickness is at least on the side of the holding element, which rests against the end face of the stack, so selected in that a rupture on the one hand by the sharp-edged panels in the stack and on the other hand tearing from the outside, be it tampering with the packaging or shocks largely prevented, corrugated cardboard is used to a comparatively low weight, sufficient Festig speed of the holding element The holding element is fixed to the stack, for example, by a foil welding of the stack together with the holding element. The holding element is configured in a trough-shaped manner, thereby achieving a particularly good fixation of the panels, in particular secure storage of the panels is achieved if other packaging or the aforementioned bands are removed. According to a further advantageous embodiment, the holding element advantageously has a For example, it is a holding element made of cardboard, in which strips of plastic are provided provided, thereby the stability of the holding element can be particularly increased, the stability serves on the one hand, the resistance On the other hand, the strength of the retaining element is increased compared to attempts to tear it or to remove it from the stack so not necessary, on more stable but at the same time to change comparatively expensive horizontal elements or packaging,

In an advantageous embodiment, the Verstarkungselement runs along at least along one of the narrow sides of the stack, It has been found that the burden is particularly high on the narrow sides and that there is a tendency to tear just on the narrow sides panel packaging.

In a further advantageous embodiment, the reinforcing element is arranged in the vicinity of at least one corner of the stack, the corners of the stack, i. the panels have sharp edges. As a result, the mechanical load on the holding element is high, in particular in the region of the corners. The reinforcement advantageously increases their stability. In one embodiment, the reinforcing element is advantageously strip-shaped or strip-shaped. As a result, the material expenditure associated with the reinforcement and thus the quantities of packaging material can advantageously be advantageously reduced.
