Description

The invention relates to a profile for connecting a pallet with at least one pallet loading frame and a transport system comprising at least one such profile.

Pallets for the transport of components are known, such pallets are provided with pallet Aufsetzrahmen to secure the components against slipping or sliding off the surface of the pallet. Wooden pallet cradles with hinges or hinged plastic are available on the market. In this case, pallet placement frames made of plastic are already available, which are produced as a hollow chamber profile in an extrusion process and an adjoining thermoforming process and are particularly stable and designed with low wall thickness and low weight compared to other frames.

Such hollow chamber plates are previously used as "rings" in special pallets with groove guide. These rings are not stackable and therefore only one ring is used in conjunction with the special range. Conventional are also on the respective ring attachable lid, which are usually adapted to the respective geometric configuration of the upper edge of the ring.

In addition to standard pallets with a smooth surface are also available, which have on their surface in the region of their circumference a circumferential elevation in the form of a safety edge. In this case, however, no closed elevation course must be present, even individual elevations arranged at a distance from each other can be arranged circumferentially. For this were so far only specially adapted to the existing collection pallet Aufsetzrahmen used. An application of such pallets and standard pallets together with any pallet placement frame, especially with those of hollow chamber profiles, and also with any lids is not possible.

It is therefore an object of the invention to provide a profile for connecting a pallet with at least one Palettenaufsetzrahmen and a transport system comprising at least one such profile.

• – die erste Profilplatte in Richtung der Längsachse gesehen eine erste Oberkante und eine erste Unterkante aufweist, wobei die erste Profilplatte länger ist als die zweite Profilplatte,
• – die zweite Profilplatte in Richtung der Längsachse gesehen eine zweite Oberkante und eine zweite Unterkante aufweist, und
• – die erste Profilplatte und die zweite Profilplatte durch ein Verbindungsstück miteinander verbunden sind, das in Richtung der Längsachse des Profils gesehen die zweite Unterkante nicht überragt.

The object is achieved for the profile for connecting a pallet to at least one pallet loading frame in that the profile comprises a longitudinal axis, a parallel to the longitudinal axis arranged first profile plate and a parallel to the longitudinal axis and the first profile plate arranged second profile plate, wherein

• The first profile plate has a first upper edge and a first lower edge when viewed in the direction of the longitudinal axis, wherein the first profile plate is longer than the second profile plate,
• - The second profile plate seen in the direction of the longitudinal axis has a second upper edge and a second lower edge, and
• - The first profile plate and the second profile plate are connected to each other by a connecting piece, viewed in the direction of the longitudinal axis of the profile, the second lower edge does not project beyond.

Such a profile, that is, an elongate member having a longitudinal, three-dimensional structure, not only allows the combination of any pallet types with a conventional pallet placing frame, but also stacking several pallet placing frames to increase the frame height with only one pallet placing frame format available.

The first profile plate is formed so far longer than the second profile plate, as the top and the bottom edge of the first profile plate are spaced further apart than the top and the bottom edge of the second profile plate.

The profile is formed in particular by a continuous casting profile, which is in particular made of plastic or aluminum. The first and second profile plate are formed integrally with the connector. Alternatively, the two profile plates and the connecting piece can also be formed and joined separately, for example by welding, soldering, gluing, etc. It is also possible that one of the two profile plates is formed integrally with the connecting piece and the other profile plate is connected thereto.

Depending on the selected manufacturing process for the profile, the connector may be present continuously between the first and second profile plate or only partially available. Furthermore, the connector may have openings which ensure a permeability of the profile in the vertical direction for gases and liquids.

In particular, it has been proven for the profile according to the invention, when the first upper edge and the second upper edge lie in a plane. As a result, the profile has on its upper side a shape which, viewed in cross-section and in the longitudinal direction of the profile, corresponds to a two-pronged fork.

Furthermore, it has proven useful if the profile seen in the direction of its longitudinal axis has a first groove adjacent to the second Lower edge is arranged and is bounded by the second profile plate and the connecting piece. Alternatively, seen in the direction of its longitudinal axis, the profile has a fourth groove, which is bounded by the first profile plate and the connecting piece. The first groove or the fourth groove allows the insertion of an existing securing edge on the surface of a pallet in the slot opening.

Preferably, the connecting piece is formed in the direction of the longitudinal axis of the profile Z- or L-shaped. The spatial orientation of the Z- or L-shaped connector is not fixed. For example, the Z- or L-shaped connector seen in cross-section and viewed in the longitudinal direction of the profile upside down and / or mirrored, etc. may be arranged.

In a preferred embodiment, the profile has seen in the direction of its longitudinal axis on a second groove which is bounded by the first profile plate and the connecting piece. Alternatively, seen in the direction of its longitudinal axis, the profile has a third groove, which is bounded by the second profile plate and the connecting piece. The second groove or the third groove allows the insertion of a frame extension of a pallet Aufsetzrahmens. Such a frame extension extends along the lower or upper edge of a pallet attachment frame and in particular has a rectangular or rounded cross-section.

The object is achieved for the transport system in that it comprises a pallet, at least one pallet attachment frame and at least one profile according to the invention for connecting the pallet to the at least one pallet attachment frame.

By inserting the profile according to the invention, it is possible to use a conventional Palettenaufsetzrahmen, in particular from hollow section, for all standard pallets and pallets with safety edge or circumferential groove. In this case, the profile is at least partially arranged circumferentially around the pallet and an annular pallet frame placed on it.

The use of particular hollow panels as pallet placement frame results in very stable frame, which are very thin in relation to pallet placement frame made of wood and injection-molded plastic. Further advantages here are the weight reduction compared to wooden frames and injection molding frames available on the market and the cleanliness class to be achieved, since there are usually no open edges.

By using the profile according to the invention for the transport system, a stacking of several pallet placement frames can advantageously be realized one above the other. As a result, the frame height per transport system can be increased almost arbitrarily, even if only pallet placement frames are available in a pallet placement frame format. In this case, the profile is attached peripherally on an existing annular pallet Aufsetzrahmen and inserted at the top of the profile another annular Palettenaufsteckrahmen. As a conclusion, a lid can be placed on a profile.

The at least one pallet placement frame is preferably designed such that it can be inserted into the profile between the first upper edge of the first profile plate and the second upper edge of the second profile plate. The profile has on its upper side in particular a shape which, viewed in cross-section and in the longitudinal direction of the profile, corresponds to a two-pronged fork. The pallet attachment frame is inserted between these forks. An insertion depth of at least 10 mm is preferred.

The pallet that can be used for the transport system has, in particular, an upper side which is flat. Alternatively, the pallet has an upper side which, in the region of its circumference, has a peripheral elevation in the form of a securing edge. In this case, however, no closed elevation course must be present, even individual elevations arranged at a distance from each other can be arranged circumferentially. But also pallets with circumferential groove or groove sections can be used. A securing edge can have, for example, a rectangular or rounded cross section.

In particular, the securing edge of a pallet with circumferential elevation is designed such that it can be inserted into the first groove or the fourth groove of the profile. This allows easy placement of standard pallet placement frames.

The at least one pallet attachment frame of the transport system has, seen in the longitudinal direction of the profile, preferably a frame extension which is designed such that it can be inserted into one of the grooves provided in the profile. This increases the stability of the stacking of several pallet placement frames. The frame extension is arranged in particular on the lower and the upper edge of the plate frame and can have a rectangular, triangular, semicircular, rounded, pointed, etc. cross-section. To allow the stacking of several pallet placement frames, the frame extension is at the Lower edge of the pallet placement frame, in particular arranged off-center and a space enclosed by the Pallettenaufsetzrahmen space away, while the frame extension is disposed on the upper edge of the Palettenaufsetzrahmens in particular off-center and a space enclosed by the Pallettenaufsetzrahmen space. But also a reverse orientation is possible.

By connecting the profile according to the invention with an annular pallet loading frame made of a hollow chamber plate or other material, these can be placed on all standard pallets and on pallets with securing edge or with circumferential groove or groove sections. As a result, the transport system is very flexible and extensively applicable.

Finally, it has proven to be advantageous for the transport system if the at least one pallet attachment frame and the at least one profile are connected to one another by a screw connection, a rivet connection, a welded connection or an adhesive bond. Alternatively, a plug or snap connection between the profile and a pallet attachment frame can be formed. This further increases the stability of the transport system and reduces the number of its individual parts to be arranged.
