Description

The invention relates to a profile for connecting a pallet with at least one pallet mounting frame, the profile comprising a longitudinal axis, a first profile plate and a second profile plate, the first profile plate having a first upper edge and a first lower edge as seen in the direction of the longitudinal axis, the first The profile plate is longer than the second profile plate, the second profile plate has a second upper edge and a second lower edge when viewed in the direction of the longitudinal axis, and the first profile plate and the second profile plate are connected to one another by a connecting piece which, when viewed in the direction of the longitudinal axis of the profile, is the second Not protruding beyond the lower edge, the connecting piece having a middle plate with a first side and a second side parallel to it, the first side facing the first profile plate and the second side facing the second profile plate, the first profile plate extending at least in part d is arranged from the connecting piece in the direction of the first upper edge at a first angle to the first side. The invention further relates to a transport system comprising at least one such profile.

Pallets for transporting components are known, such pallets being provided with pallet mounting frames to secure the components against slipping or sliding off the surface of the pallet. Pallet collars made of wood with hinges or plastic with hinges are available on the market. Pallet attachment frames made of plastic are already available, which are manufactured as a hollow profile, hollow sheet or structural chamber sheet in an extrusion process and a subsequent thermoforming process and, compared to other frames, are particularly stable and have a low wall thickness and low weight.

Such twin-wall sheets have been used as "rings" in special pallets with groove guides. These rings cannot be stacked on top of one another and therefore only one ring can be used in conjunction with the special pallet. Lids that can be placed on the respective ring, which are usually adapted to the respective geometric configuration of the upper edge of the ring, are also common.

In addition to standard pallets with a smooth surface, those are also available which have a circumferential elevation in the form of a safety edge on their surface in the area of their circumference. In this case, however, there does not have to be a closed elevation course; individual elevations arranged at a distance from one another can also be arranged circumferentially. Previously, only pallet collars that were specially adapted to the existing elevation could be used for these. The use of such pallets and standard pallets together with any desired pallet mounting frames, in particular with those made of hollow chamber profiles, and also with any desired covers has not been possible up to now.

The DE 31 10 705 A1 describes a material container that consists of a cuboid frame structure with upper and lower chords and four corner posts into which trapezoidal sheets are inserted.

The DE 20 2011 102 598 U1 discloses a multipart pallet attachment packaging and a box pallet.

US 2012/0 017 809 A1 describes a load carrier in the form of a pallet.

It is therefore the object of the invention to specify a profile for connecting a pallet to at least one pallet mounting frame 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, wobei das Verbindungsstück eine Mittelplatte mit einer ersten Seite und einer dazu parallelen zweiten Seite aufweist, wobei die erste Seite der ersten Profilplatte und die zweite Seite der zweiten Profilplatte zugewandt ist, und wobei die erste Profilplatte zumindest in einem Teilstück ausgehend von dem Verbindungsstück in Richtung der ersten Oberkante in einem ersten Winkel α zu der ersten Seite angeordnet ist, und wobei die zweite Profilplatte in Richtung der Längsachse gesehen ein oberhalb des Verbindungsstücks angeordnetes erstes Teilstück und ein unterhalb des Verbindungsstücks angeordnetes zweites Teilstück aufweist, wobei das zweite Teilstück parallel zur zweiten Seite der Mittelplatte ausgerichtet ist.

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

• - The first profile plate has a first upper edge and a first lower edge as seen in the direction of the longitudinal axis, the first profile plate being longer than the second profile plate,
• - The second profile plate has a second upper edge and a second lower edge as seen in the direction of the longitudinal axis, and
• The first profile plate and the second profile plate are connected to one another by a connecting piece which, viewed in the direction of the longitudinal axis of the profile, does not protrude beyond the second lower edge, the connecting piece having a central plate with a first side and a second side parallel thereto, the first side facing the first profile plate and the second side of the second profile plate, and wherein the first profile plate is arranged at least in part starting from the connecting piece in the direction of the first upper edge at a first angle α to the first side, and the second profile plate in the direction viewed along the longitudinal axis, has a first section arranged above the connecting piece and a second section arranged below the connecting piece, the second section being aligned parallel to the second side of the central plate.

Such a profile, i.e. an elongated element with a longitudinal, three-dimensional structure, enables not only the connection of any type of pallet with a conventional pallet attachment frame, but also the stacking of several pallet attachment frames on top of one another to increase the frame height with only one available pallet attachment frame format. The angling of the first profile plate at the first angle α enables a particularly simple insertion of a pallet mounting frame into the profile and creates an optimal frictional connection between the pallet mounting frame and the profile.

The first angle α is in particular in the range from 0.1 ° to 10 °. The first angle α is preferably in the range from 0.5 ° to 3 °.

The first profile plate is made longer than the second profile plate in that the upper and lower edges of the first profile plate are spaced further apart than the upper and lower edges of the second profile plate.

The profile is formed in particular by a continuously cast profile which is made in particular from plastic or aluminum. The first and second profile plates are formed in one piece with the connecting piece. Alternatively, the two profile plates and the connection piece can also be formed separately from one another and joined together, for example by welding, soldering, gluing, etc. Furthermore, it is possible that one of the two profile plates is formed in one piece with the connection piece and the other profile plate is connected to it.

Depending on the manufacturing process chosen for the profile, the connecting piece can be present continuously between the first and second profile plate or only be present in sections. Furthermore, the connecting piece can have openings which ensure that the profile is permeable to gases and liquids in the vertical direction.

The first profile plate is preferably arranged starting from the connecting piece in the direction of the first lower edge at a second angle β to the first side. This makes it easier to place the profile on a pallet or a pallet mounting frame. The second angle β is in particular in the range from 0.1 ° to 10 °, preferably in the range from 0.5 ° to 3 °.

The first upper edge and the second upper edge as well as the first lower edge are preferably rounded in order to avoid tilting of the profile when the profile is placed on a pallet or when a pallet mounting frame is inserted into the profile.

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

The second lower edge, on the other hand, is particularly flat and perpendicular to the second side of the middle plate of the connecting piece.

Furthermore, it has proven useful if the profile has a first groove, viewed in the direction of its longitudinal axis, which is arranged adjacent to the second lower edge and is delimited by the second profile plate and the connecting piece. The first groove enables an existing safety edge on the surface of a pallet to be inserted into the groove opening.

The profile preferably has a second groove, viewed in the direction of its longitudinal axis, which is delimited by the first profile plate and the connecting piece. The second groove enables a frame extension of a pallet mounting frame to be inserted. Such a frame extension extends along the lower or upper edge of a pallet mounting frame and in particular has a rectangular or rounded cross-section.

The connecting piece has, seen in the direction of the longitudinal axis of the profile, starting from the middle plate in the direction of the second upper edge, a transition area with an arcuate course. This makes it easier to insert a pallet mounting frame into the second groove.

According to the invention, the second profile plate, viewed in the direction of the longitudinal axis, has a first section arranged above the connecting piece and a second section arranged below the connecting piece, the second section preferably being aligned parallel to the second side of the central plate.

Viewed in the direction of the longitudinal axis, the first section of the second profile plate is preferably arranged offset with respect to the second section in the direction of the first profile plate.

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

By using the profile according to the invention, it is possible to use a conventional Pallet attachment frames, in particular made of a hollow chamber panel or a structured chamber panel, can be used for all standard pallets and also pallets with a safety edge or a circumferential groove. The profile is arranged at least partially around the pallet and an annular pallet mounting frame is placed on it.

The use of, in particular, twin-wall panels as pallet mounting frames results in very stable frames which are very thin in relation to pallet mounting frames made of wood and injection-molded plastic. Further advantages here are the weight reduction compared to wooden frames and injection-molded frames available on the market as well as 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 mounting frames on top of one another can advantageously be realized. This allows the frame height per transport system to be increased almost at will, even if only pallet collars are available in one pallet collet format. In this case, the profile is pushed all the way around an already existing ring-shaped pallet mounting frame and another ring-shaped pallet mounting frame is inserted on the top of the profile. As a conclusion, a cover can also be placed on a profile.

For this purpose, the at least one pallet attachment frame is preferably designed in such a way 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. On its upper side, the profile has 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 mounting frame is inserted between these forks. An insertion depth of at least 10 mm, in particular of at least 30 mm, is preferred.

The pallet that can be used for the transport system has, in particular, an upper side that is flat. Alternatively, the pallet has a top side which has a circumferential elevation in the form of a safety edge in the area of its circumference. In this case, however, there does not have to be a closed elevation course; individual elevations arranged at a distance from one another can also be arranged circumferentially. However, pallets with a circumferential groove or groove sections can also be used. A safety edge can have a rectangular or rounded cross-section, for example.

In particular, the securing edge of a pallet is designed with a circumferential elevation in such a way that it can be inserted into the first groove of the profile. This enables a problem-free attachment of standard pallet collars.

The at least one pallet attachment frame of the transport system, viewed in the longitudinal direction of the profile, preferably has a frame extension which is designed such that it can be inserted into one of the grooves present in the profile. This increases the stability of the stacking of several pallet collars. The frame extension is arranged in particular on the lower and the upper edge of the panel attachment frame and can have a rectangular, triangular, semicircular, rounded, tapered etc. cross section. In order to enable the stacking of several pallet attachment frames, the frame extension is arranged on the lower edge of the pallet attachment frame, in particular eccentrically and facing away from a space enclosed by the pallet attachment frame, while the frame extension on the upper edge of the pallet attachment frame is arranged, in particular, eccentrically and faces a space enclosed by the pallet attachment frame.

By connecting the profile according to the invention to an annular pallet attachment frame made of a hollow-chamber sheet or another material, these can be placed on all standard pallets and on pallets with a safety edge or with a circumferential groove or groove sections. This makes the transport system very flexible and comprehensive.

Finally, it has proven useful for the transport system if the at least one pallet mounting 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 can be formed between the profile and a pallet mounting frame. This further increases the stability of the transport system and reduces the number of its individual parts to be arranged in relation to one another.
