Description

The present invention relates to a loading device intended for use in loading and unloading goods on a load carrier, preferably a pallet, as well as for securing and transporting the goods arranged on the load carrier.

Loading devices are known from the prior art. They are used primarily for transporting goods. For goods to be transported, the goods must be secured to the load carrier. For this purpose, it is known in the prior art to use external (stretch) films to secure the goods to the load carrier. It is also known to design the entire loading device as a box or container, whereby goods can be inserted into the box or closed container and subsequently removed again.

The term “carrier” is used in the DIN standard 30781 (As of February 2024) is defined as a load-bearing means for combining goods into a loading unit. A loading unit is understood to be the load carrier containing the goods. In industrial environments, standardized load carriers such as Euro pallets or plastic containers of various sizes are often used. When using Euro pallets, it is common practice to secure the load with (stretch) film, as explained previously.

The advantage of plastic containers is that the laborious removal of the film to retrieve the goods and subsequent disposal of the film can be avoided. A disadvantage of conventional plastic containers, however, is that loading and unloading the transported goods is comparatively complex and, in particular, cannot be automated. However, wrapping a Euro pallet loaded with goods with film can be automated. Therefore, Euro pallets are used as load carriers for transporting the goods, particularly in automated high-bay warehouses.

As a result, it is not only necessary to ensure that the load carrier can carry the load when transporting goods, but the goods must also be adequately secured for transport.

Ultimately, in practice, no loading units are known that can be used in an automated high-bay warehouse where loading and unloading can also be carried out automatically. This is particularly useful when goods within the high-bay warehouse change locations or are intended for external/further transport.

The object of the present invention is therefore to provide a loading device of the type mentioned above which improves the transport of goods, in particular in an automated high-bay warehouse.

The above-mentioned object is at least essentially achieved by a charging device according to claim 1.

The subclaims are preferred embodiments and further developments of the charging device according to the invention.

The loading device according to the invention is intended for use in loading and unloading goods onto a load carrier. In particular, the loading device can be used for the automated loading and unloading of goods in an automated high-bay warehouse.

A pallet, in particular a Euro pallet, is preferably provided as the load carrier. The load carrier is not part of the loading device; rather, the loading device can interact with the load carrier and the goods arranged on the load carrier, as explained below.

The loading device is designed to secure and transport the goods arranged on the load carrier. For this purpose, the loading device comprises a wall that is open at the upper and lower ends and designed to accommodate the loaded and unloaded load carrier. The wall is designed such that the height of the load carrier is adjustable within the wall over the entire height of the wall when loaded or unloaded.

The advantage of the loading device according to the invention is that, on the one hand, it enables the securing of goods with a rigid or, in use, fixed loading device. This avoids the additional attachment of film to secure the goods arranged on the load carrier, while the loading device is reusable. For ecological reasons, this loading device is therefore particularly preferred.

At the same time, the securing of the transported goods can also be improved by the loading device, as the loading device ensures stability during transport of the transported goods. This represents a significant improvement over wrapping transported goods with film.

The loading device therefore offers the advantage of leveraging the transport safety benefits of a closed plastic container, while simultaneously allowing a familiar load carrier, such as a pallet, to be used to support the load during transport. This ensures easy loading and unloading of goods, as the height of the load carrier is adjustable within the enclosure.

Height adjustment is achieved by designing the loading device so that it is open both at the top and bottom. The top of the loading device is particularly open with an opening cross-section that exceeds the area of the load carrier to be arranged in the loading device. The bottom of the loading device is also open. However, this opening does not have to correspond to the cross-section of the load carrier to be arranged in the loading device. In particular, the bottom of the loading device is open in such a way that a lifting device for moving or raising or lowering the load carrier within the loading device can be arranged below the loading device. This lifting device can then move the load carrier with the goods provided on it as required within the loading device by raising or lowering the load carrier.

The height adjustment of the load carrier within the enclosure also enables the loading device to be used in an automated loading and unloading process, particularly in a high-bay warehouse, without the need for human intervention.

The loading system thus significantly simplifies the loading and unloading of goods in a high-bay warehouse and enables efficient transport of goods without generating packaging waste from film. The need for operator intervention during loading and unloading can also be avoided.

This also means that the costs for loading and unloading goods can be significantly reduced, making the loading facility particularly advantageous not only from an ecological but also from an economic point of view.

In a particularly preferred embodiment, the cross-sectional shape of the interior of the enclosure is at least substantially shaped to match the cross-sectional shape of the outer cross-section of the loaded load carrier. Shape adaptation within the meaning of the present invention means that the load carrier can be arranged within the enclosure. The load carrier is then arranged within the enclosure with only slight play, so that the enclosure can also ensure the securing of the goods during transport. The cross-sectional shape of the interior of the enclosure can thus be designed to complement the outer shape of the load carrier. However, a certain amount of play of the load carrier within the enclosure, in particular in the range of up to 15 mm per side, is preferred, so that certain tolerances for inserting and removing the load carrier from the loading device are present during transport and in the automated process.

Furthermore, in a further preferred embodiment, the interior of the enclosure can have an inner cross-section across its entire height that is larger than the outer cross-section of the load carrier. This applies in particular to the standardized dimensions of a Euro pallet. This allows the load carrier to be height-adjustable within the interior of the enclosure across the entire height of the enclosure.

Particularly preferably, the dimensions of the cross-sectional shape of the interior of the enclosure are such that the load carrier is arranged within the interior of the enclosure with a certain amount of clearance. This clearance ensures, in particular, that there is no need for a precise fit between the interior shape of the enclosure and the exterior shape of the load carrier, so that different load carriers can be equipped with the same loading device for transporting goods. At the same time, it is common in automated processes that tolerances are required to avoid complex coordination of the insertion of the load carrier into the enclosure.

In a further preferred embodiment, the enclosure comprises a plurality of wall sections. In particular, the enclosure comprises four wall sections. The wall sections can be connected to one another or connectable to one another. Particularly preferably, the wall sections are designed to be rigid, thereby enabling load security during transport of goods. The enclosure preferably has a closed rectangular cross-section.

In addition, adjacent wall sections are preferably connected to each other by hinges. Alternatively or additionally, It can be that all wall sections are made from a common wall piece, in particular wherein material thinnings, in particular in the form of a film hinge, are provided in the joint areas. When producing the wall from a common wall piece, it is then necessary to connect two wall sections to one another, in particular in a form-fitting, force-fitting and/or material-fitting manner. In particular, the film hinge forms a slope, in particular a 45° slope, in relation to the respective adjacent wall sections, wherein adjacent wall sections are connected to one another via a corner connecting the wall sections. The corner can in turn form the aforementioned 45° slope.

Accordingly, a rigid design of the individual wall sections can be provided. The enclosure itself can (but does not have to) be rigid. In particular, it can be provided that the enclosure can be folded when not attached to a load carrier, so that the enclosed opening cross-section of the enclosure does not have a rectangular shape, but rather individual wall sections can lie on top of one another.

This is particularly advantageous for transporting the loading device, as the increased space required is only needed for transporting the goods. If the loading device is subsequently stowed or transported without the goods, it can be folded up for storage capacity reasons, which not only simplifies but also improves the use of the loading device.

In a further, particularly preferred embodiment, the material of the enclosure comprises and/or consists of plastic, in particular polypropylene (PP). Such a material for the enclosure ensures, in particular, that sufficient stability of the enclosure or the individual wall sections of the enclosure can be guaranteed.

Particularly preferably, at least one wall section is designed as a structural chamber panel, in particular as a PP structural chamber panel or as a polypropylene structural chamber panel. Structural chamber panels are panels with an internal structure to increase stability. The structure arranged inside the structural chamber panel can take on various forms, for example, a dimpled central layer or a framework. Finally, a structure that increases stability and rigidity is attached inside the structural chamber panel. Thus, the structural chamber panel can have at least two outer layers and a structure arranged between the outer layers. If necessary, a multi-layer structure of the structural chamber panel can also be provided.

Preferably, the wall has a height of at least 200 mm, in particular between 300 mm and 4000 mm, preferably between 500 and 2000 mm. The height of the wall is selected depending on the goods to be transported or the intended purpose.

The wall section can have a wall thickness between 1 and 50 mm, preferably between 2 and 20 mm, in particular between 8 and 15 mm. A wall thickness of the aforementioned type ensures sufficiently high stability of the wall section.

In a further particularly preferred embodiment, it is provided that at least one centering means projecting into the interior space is provided on the inside of the wall for centering the load carrier in the wall.

In particular, the centering means is formed on at least one wall section, in particular on all wall sections, by an inner insertion bevel, preferably provided in the upper end region. The insertion bevel can enable simplified insertion of the load carrier into the interior. Preferably, the insertion bevel can reduce the play of the load carrier in the interior of the wall by 1 mm to 2 mm. The orientation of the insertion bevel can be provided in two different variants. Ultimately, the question is whether the bevel - starting from the outside of the wall to the inside of the wall - is designed to be ascending or descending. It is particularly preferred if the bevel is designed to be descending from the outside to the inside of the wall, so that the play of the load carrier in the loading device is reduced when inserted into the wall. However, the other variant for centering the load carrier within the wall is also possible; the insertion bevel can also be designed to rise, at least in some areas, from the outside to the inside of the wall.

In a further embodiment, the centering means can also have a projection with at least one insertion bevel, in particular with both a descending and a rising bevel.

Alternatively or additionally, it can also be provided that a further centering means—also independent of the (first) centering means, if necessary—is provided in the lower region of the enclosure. The further centering means can, in particular, have at least one insertion bevel. Finally, a centering means arranged in the lower region of the enclosure enables centering of the load carrier in the loaded state, in particular wherein the further centering means can face the underside of the loading device or be arranged on it.

In a further, particularly preferred embodiment, a substructure is arranged on the underside of the enclosure for gripping underneath the load carrier. For example, the substructure can be designed to allow a forklift to grip underneath for raising or lowering the loading device.

In particular, the substructure also ensures a captive arrangement of the loading device on the load carrier. The substructure allows for a reduction in the opening cross-section of the loading device on the underside. Thus, the substructure can also be designed to be open at the upper and lower ends, in particular with the upper end of the substructure directly adjacent to the enclosure, merging into it, and/or being connected to it.

It is particularly preferred that the substructure on the lower end face be designed to partially enclose and/or surround the load carrier. This enables, in particular, a captive arrangement of the load carrier in the loading device and thus also allows the loading device and the load carrier to be transported captive during the transport of goods.

Preferably, the substructure can be firmly connected to the enclosure, in particular by a material fit, friction fit, and/or form fit, and/or formed integrally with the enclosure. The substructure thus ensures the stability of the loading device.

For the arrangement of the wall, a circumferential groove or step can be provided in the substructure, into which the wall engages with its lower edge. The edge of the wall can, in particular, have a step or groove complementary to the groove or step of the substructure. The groove or step of the substructure has the advantage of enabling easy positioning of the wall on the substructure for assembly or installation of the loading device.

In a further preferred embodiment of the loading device, the inner side of the wall is at least substantially aligned with the inner side of the substructure, in particular wherein the aforementioned inner sides merge into one another at least substantially seamlessly. Such a design enables the advantages of improved movement of the load carrier in the interior of the loading device. In particular, an aligned arrangement of the inner sides of the substructure and the wall can be enabled in the transition area between the wall and the substructure, so that in particular disruptive contours during the movement of the load carrier within the loading device can be avoided. Furthermore, damage to the transported goods caused by any protruding contours can be avoided.

The substructure is preferably constructed in multiple parts and comprises, in particular, two shorter end sections and/or two longer longitudinal sections. In particular, each end section is firmly connected to two longitudinal sections, preferably by a material fit, friction fit, and/or form fit. This allows for the provision of a closed frame.

Preferably, the longitudinal sections on opposite sides of the substructure can be of identical construction. Alternatively or additionally, the end sections on opposite sides of the substructure can be of identical construction. This enables, in particular, simplified production of the substructure and leads to reduced production costs.

The substructure can be designed such that the height of the load carrier is larger relative to the height of the substructure, so that in particular the load carrier projects beyond the substructure when arranged in the loading device.

Furthermore, in another preferred embodiment, the longitudinal section has at least two feet for gripping underneath the corners of the load carrier. Alternatively or additionally, the longitudinal section can be designed as a runner that grips underneath the load carrier over its entire length. The runner can, in particular, have an elongated underside that runs the length of the load carrier.

The skid design is particularly advantageous for transporting the loading unit comprising the loading device, the load carrier, and the load arranged on the load carrier, preferably via roller conveyors or the like, as this ensures low-vibration transport of the goods or the load. It also avoids disruptive edges that could potentially cause damage to the conveyor belts or the loading device itself.

The feet have the advantage that the substructure can be gripped not only at the front sides, but also at the long sides, whereby, if necessary, appropriate lifting equipment, such as a forklift, can then grip the load carrier not only at the front sides of the substructure, but especially also at the long sides, which is advantageous depending on the different load carriers.

The feet can have a bottom side and side walls adjoining the bottom side and can be arranged in particular in the corner areas of the charging device.

The runner can also be connected to the wall via a corresponding side wall section.

Particularly preferably, the end section has an end wall adjoining the wall section, wherein, preferably, at least one projection angled toward the interior of the wall is provided on the end wall, which projection serves in particular to engage underneath the load carrier. The end section, through the end wall, particularly increases the stability of the entire substructure, which interacts with the load carrier when the load carrier is loaded.

The height of the end wall of the end section can be less than the height of the longitudinal section, although the upper edges of the end and longitudinal sections, which face the surrounding wall, can be aligned or arranged in a straight plane. Such a design results in particular in improved adaptation to a load carrier designed as a Euro pallet, which in particular has corresponding recesses for the engagement of a forklift truck on the end sides, which extend over the length of the load carrier. Therefore, a lower height of the end wall ensures that such an engagement can be ensured for transporting the loading device and/or the load unit.

Preferably, the projection of the front section is arranged offset from the underside of the runner or the support foot.

The end section can particularly preferably have two projections. Alternatively or additionally, the projection can have a ramp at its free end on the underside facing away from the wall. The ramp also enables the improved arrangement of transport means, such as a forklift, and in particular the insertion and/or landing of the forks of the forklift.

In a further preferred embodiment, it is provided that the material of the substructure, in particular of the support section, comprises and/or consists of polypropylene (PP) and/or polyoxymethylene (POM) and/or differs from the material of the surrounding wall, in particular is designed to be more resistant. The material of the substructure is designed to be particularly wear-resistant, with PP and/or POM being particularly suitable in this context, as they have a high level of resistance. The substructure is exposed to wear in particular from transport along roller and/or conveyor belts, but also from transport by transport vehicles such as forklifts. A resistant material for the substructure therefore ensures long-term use of the loading device.

Furthermore, the present invention relates to a method for loading and unloading goods onto a load carrier, preferably a pallet, as well as for securing and transporting the goods arranged on the load carrier, particularly in a preferably automated high-bay warehouse. The method comprises the following method steps, preferably in the specified order:

1. A) Providing a charging device according to one of the preceding embodiments;
2. B) Arranging a load carrier, in particular a pallet, in the enclosure of the loading device;
3. C) Arranging a lifting device on the underside of the load carrier arranged in an underside, open area of the loading device;
4. D) Lifting and/or lowering the load carrier in the enclosure of the loading device via the lifting device to a loading position;
5. E) Loading the load carrier located in the respective loading position with goods;
6. F) Lowering the load carrier in the enclosure using the lifting device into a transport position, in particular in which the load carrier is adjacent to and/or resting on the substructure.

With regard to advantages and/or preferred embodiments, reference may be made to the aforementioned statements regarding the charging device, which also apply equally to the method according to the invention. In particular, the following statements regarding the method also apply equally to the charging device according to the invention, in particular without requiring further explicit explanation.

In the automated method according to the invention, the advantageous feature of the loading device for automated loading and unloading is particularly advantageous. This allows, in particular, the load carrier to be loaded with goods in stages.

In a particularly preferred embodiment, it is provided that the load carrier is lowered step by step into individual loading positions, so that in particular a continuous loading with goods takes place at least substantially. Continuous loading with goods is to be understood that the load carrier is lowered step by step as soon as a corresponding layer of goods has been loaded or filled onto the load carrier. Such lowering then enables the goods to be fed in again. The goods can in particular be fed to the load carrier via the front side of the wall, so that in particular the goods arranged on the load carrier are at least substantially aligned with the open front side of the wall, so that easy loading can take place.

The continuous loading and/or unloading of goods, as well as the control of the infeed and outfeed of goods via belts or other conveying means, is carried out by a control device, which is associated with sensors for monitoring the loading and/or unloading process. The infeed or outfeed device and the lifting device are also coupled to the control device.

The lifting device used in the method according to the invention can be designed in different ways. Appropriate lifting tools, when arranged on the open underside of the loading device, in particular on the underside of the substructure, enable the load carrier to be raised and lowered accordingly. The load carrier can then be removed from the loading device once the goods have been removed from it. If necessary, however, the load carrier, along with the goods arranged on it, can also be removed from the interior of the loading device's enclosure by lifting the load carrier.

The load carrier can also be unloaded step by step. This allows the load carrier to be raised gradually within the enclosure, allowing individual layers or levels of goods to be removed from the top. The unloading of the goods depends on the goods to be transported and can be individually adapted to different process configurations.

Furthermore, it is expressly pointed out that all the intervals mentioned above and below include all intermediate intervals and individual values contained therein and that these intermediate intervals and individual values are to be regarded as essential to the invention, even if these intermediate intervals or individual values are not specifically specified in detail.

Further features, advantages and possible applications of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawings and the drawings themselves. All described and/or illustrated features, individually or in any combination, form the subject matter of the present invention, regardless of their summary in the claims or their reference back to them.

The 1 shows a loading device 1 intended for use in loading and unloading goods 2 on a load carrier 3. The 1 shows in this context the loading process using the loading device 1. The load carrier 3 is designed in particular as a pallet, as the 1 Particularly preferably, the load carrier 3 is a so-called Euro pallet, which has a defined shape and size. A Euro pallet is a standard pallet according to EN 13698-1 (As of February 2024) with a base area of 0.96 ^m² and dimensions of 1,200 mm × 800 mm × 144 mm (length × width × height) and a dead weight of 20 to 24 kg (depending on the wood moisture content). It consists of 11 boards and 9 blocks and is held together by 78 nails. The gaps between the boards on the top of a Euro pallet are typically 40 to 43 mm wide.

The loading device 1 also serves to transport and secure the goods 2 arranged on the load carrier 3. The goods 2 are in the 1 also shown schematically.

It is understood that different forms of goods 2 can be used. In 1 It is shown that the goods 2 are arranged in individual layers 32. The individual layers 32 are supplied to the loading device 1 in the 1 In the embodiment shown, the material is fed via a conveyor belt 33, in particular a roller belt. For loading the loading device 1, a lifting device 30 is also provided, which will be discussed below. The drive and the specific design of the lifting device 30 are shown in the 1 shown only schematically. The lifting device 30 is intended to move the load carrier 3 up or down within the loading device 1 or to raise or lower the load carrier 3.

1 further shows that the charging device 1 has a on the upper end face 4 and the lower end face 5, which are shown in more detail in the 3 is shown, has an open enclosure 6. The upper end face 4 of the enclosure 6 can also form the upper end face of the loading device 1. The lower end face 5 of the enclosure is in the 1 illustrated embodiment, the lower end face 38 of the loading device 1 is not open, whereby the lower end face 38 of the loading device 1 can also be designed to be open at least in some areas. The open lower end face 38 of the loading device 1 allows access to the load carrier 3, in particular for the lifting device 30, as the 1 This is shown schematically.

The transformation 6 as such is also shown schematically in the 15 shown in a further embodiment.

When the goods 2 are arranged in the loading device 1, it is provided in particular that the wall 6, at least partially, preferably completely, surrounds the goods 2 or the layers 32 with the goods 2, as the 4 shows.

In 3 it is shown that the wall 6 is designed to receive the loaded or unloaded load carrier 3. 3 shows the reception of the loaded load carrier 3, whereas for a further embodiment of the loading device 1 in 5 the absorption of the charge carrier 3 in the enclosure 6 is shown in the discharged state.

The 1 It also illustrates that the enclosure 6 is designed such that the load carrier 3, when loaded or unloaded, is height-adjustable in the interior 7 of the enclosure 6 over the entire height 8 of the enclosure 6. Furthermore, the height adjustment can also be enabled over the entire height 11 of the loading device 1.

The height adjustment made possible according to the invention has the advantage that the loading device 1 can be loaded step by step with goods 2, as shown schematically in 1 is shown. Thus, after each loading step, for example with a layer 32, the load carrier 3 can be lowered into the enclosure 6, in particular via the lifting device 30, so that a further layer 32 with goods 2 can be arranged on this layer 32 already arranged on the load carrier 3. The enclosure 6 is designed such that the load carrier 3 is adjustable over the entire inner height 11 of the loading device 1.

The open end faces 4, 5 of the enclosure 6 also enable access to the load carrier 3 arranged within the enclosure 6. The load carrier 3 can thus be both loaded and unloaded within the enclosure 6 and simultaneously raised or lowered within the enclosure 6. If the lower end face 5 of the enclosure 6 were closed, lower actuation of the load carrier 3 would not be possible.

The height adjustment enabled across the entire height 8 of the enclosure 6 further provides the advantage that any loading and unloading position of the load carrier 3 within the enclosure 6 can be specified, particularly depending on how this is required for different goods 2. Thus, the loading device 1 can be loaded or unloaded, in particular, with different goods 2, whereby the respective height of the load carrier 3 in the enclosure 6 can also be specified depending on the different goods 2.

If the load carrier 3 is arranged in the wall 6 without the lifting device 30, the load carrier 3 lies, in particular in or on the lower area of the wall 6, as the 5 and 6 clarify.

The 3 further shows that the cross-sectional shape of the interior 7 of the wall 6 is at least substantially adapted to the cross-sectional shape of the outer cross-section of the (loaded) load carrier 3. In addition, the 3 that the interior space 7 of the wall 6 has an internal cross-section over its entire height 8 which is larger than the external cross-section of the load carrier 3. The aforementioned features depend on the load carrier 3. Depending on different load carriers 3, the charging device 1 can therefore also be designed differently or the charging device 1 is provided with a shape adapted to different load carriers 3. Although the invention relates in particular only to the charging device 1 as such, the shape of the charging device 1 results from the interaction with the load carrier 3, which can also be removed from the charging device 1 again if necessary.

An adaptation of the cross-sectional shape of the interior 7 and also of the inner cross-section of the wall 6 to the load carrier 3 enables the load carrier 3 to be height-adjustable over the entire height 8 of the wall 6 when arranged in the wall 6, as is also the case with the 3 clarified.

In 15 It is shown that the wall 6 has a plurality of wall sections 9. This is also the case in the 3 to 11 illustrated embodiments of the charging device 1. In the respective illustrated embodiment, in particular four wall sections 9 are provided for the enclosure 6. The wall sections 9 are connected to each other.
