Definitions

  • the invention relates to a pallet, in particular for transporting goods.
  • pallets of uniform dimensions are used on a large scale, which usually circulate in the context of deposit systems.
  • the pallets are used to hold the packaged and lashed goods for transport by forklift, truck or train, as well as to store the goods in warehouses.
  • This pallet has an upper deck, closed at its upper side by a flat, closed surface. On its underside honeycomb cells are formed.
  • the pallet also includes a lower deck closed at the bottom and fitted with honeycomb cells at the top. The two decks are welded together flat. From below, feet are welded to the lower deck, three of which are connected to each other by a bridge.
  • This pallet is suitable as a hygiene pallet, especially for the transport of food. However, it is subject to restrictions in terms of resilience. Will the
  • the pallet according to the invention has a lower pallet deck, on which feet are integrally formed.
  • the upper pallet deck and the lower pallet deck are welded together. This weld is the only essential weld on the pallet.
  • the pallet decks are made of a fiber-reinforced plastic, preferably a long-fiber reinforced plastic, pallets can be produced which, with the same dimensions as a wooden pallet, can carry higher loads than these.
  • the welded joint is limited to the plane between the two upper decks.
  • the fibers embedded in the plastic for example glass fibers of 6 to 25 mm in length, initially face each other with their front sides. When the weld is formed, beads form on the honeycomb edges in which the fibers are entangled or matted together.
  • the fibers are otherwise wall-parallel, ie oriented predominantly approximately parallel to the outer sides and other surfaces of the decks and the honeycomb cell walls.
  • the long glass fibers or other fibers flowing with the plastic thus also wrap around bends and corners of the plastic without breaking, so that the formed feet are produced without interrupting the course of the fibers. This results in a high strength.
  • no glass fiber reinforced transition can be achieved, ie the fibers do not pass through the seam.
  • the invention helps here and leads to a Design in which the fibers of the lower deck - interruption-free extend into the feet.
  • the pallet decks are preferably mirror-welded together.
  • the edges of the honeycomb cells are heated over their entire surface and pressed against each other so that the fibers are entangled and the plastics frayed.
  • other welding methods such as friction welding, ultrasonic welding or suitable bonding can be used.
  • the upper and lower pallet deck can be made of the same plastic. However, it is also possible to manufacture the pallet decks of different plastics. For example, the upper pallet deck can be made of a primary plastic and the lower pallet deck made of a recycled plastic. This results in an upward, i. on the side facing the goods, a hygienic harmless surface while the lower pallet deck can be produced at a reduced cost.
  • long fiber-filled plastics are preferred. These contain glass fibers or other fibers whose average length of fibers is significantly greater than the thickness of the walls to be produced.
  • a suitable manufacturing method for example a transfer molding method, it is possible to achieve that the fibers in the production process are aligned parallel to the wall, ie parallel to the respectively adjacent surface. Smooth surfaces are obtained from which no fiber ends protrude. This is to be preferred both from the point of view of material strength and from the point of view of surface quality and hygiene.
  • a suitable manufacturing driving is a transfer molding process in which viscoplastic, fiber-filled plastic is injected into a partially closed injection molding mold, after which the mold is completely closed. The injection into the not yet completely closed form has the advantage that a good mold filling can be achieved. The subsequent closing of the mold is similar to a pressing process, in which the alignment of the fibers is achieved by the flow of the plastic plastic.
  • Both pallet decks preferably have uniform and congruent honeycomb patterns. This ensures that when welding the pallet decks, the edges of the honeycomb cells meet to form a bead-like weld seam. In this case, preferably as much material is laterally displaced from the honeycomb cell edges that forms an almost closed surface between the pallet decks. In this way, a good entanglement of the fibers contained in the plastic is achieved in the weld region. In addition, in this way, the height of the produced, forming the pallet composite plate can be regulated.
  • the feet have a honeycomb cell pattern that differs from the rest of the honeycomb cell pattern of the lower pallet deck.
  • the honeycomb cells in the feet are preferably much larger than the other honeycomb cells of the lower pallet deck. This facilitates the molding of the lower pallet deck after the transfer molding process.
  • each foot has an intermediate floor. This is arranged, for example, below the middle of the height of the foot. Further preferably lies This intermediate floor above bars that connect the lower ends of the feet together.
  • the intermediate floor gives the feet lateral rigidity, so that they do not collapse even when they are under considerable load and are pushed, for example, with the tips of the forks of a fork-lift truck.
  • Below the false bottom further honeycomb cells are preferably arranged, these honeycomb cells then being open towards the bottom.
  • the lower honeycomb cells preferably differ from the upper honeycomb cells. They can have a considerably smaller cross-section than the upper honeycomb cells. This too can benefit the firmness of the feet.
  • the intermediate floor is at a height of, for example, 30 to 70 mm in a region which is usually hit by the tip of a fork-lift fork lying on the ground.
  • the webs connecting the feet are preferably provided with ribs on their underside.
  • the spaces between the ribs are open. This has the advantage that the pallet thus formed gets a secure footing even on uneven ground. Individual pebbles or other smaller objects lying on the floor are neither pressed into the ground nor do they cause a pallet to tip over. Rather, they find themselves in the honeycomb cells of the feet or between the ribs of the webs.
  • the plastic pallets have closed honeycomb cells.
  • they can have a receiving compartment for receiving a manually optically or a machine-readable data carrier.
  • the receptacle can be a honeycomb cell.
  • the receptacle can also be arranged in a mechanically slightly loaded, visible from the outside and protected area, such as a tray be arranged on an outside of a foot.
  • This compartment can be provided with a viewing window, wherein it can be designed so that manually readable data carriers, such as labels or cards, can be inserted.
  • manually readable data carriers such as labels or cards
  • Disk such as by radio waves or other radiation readable chips to install in the range.
  • identification devices usually contain a flat coil and a chip connected thereto. At least the reading of data that can identify the pallet can be done by high frequency radio waves.
  • identification devices are often referred to as RF-ID devices.
  • this device can also be created in such a way that information can be introduced into the identification device in order to identify, for example, the goods lying on the pallet.
  • the identification device only serves the distinctive marking of the pallet. Both variants can be used to achieve local, regional or global pallet tracking.
  • the corresponding identification devices can be permanently installed in the pallets, for example embedded in their plastic. This can be done in the production of pallets in the transfer molding process. If required, the identification devices can be surrounded by a jacket, which protects them from being exposed to high temperatures of the viscoplastic during manufacture when it flows around the identification device.
  • the identification device in a honeycomb cell, preferably the lower pallet deck, For example, insert an external honeycomb cell of a pallet foot before the lower pallet deck is welded to the upper pallet deck.
  • the identification device can be secured in place in the honeycomb cell by foam or other suitable holding means in place, for example to keep it on the outside. Also in this case, the identification device is held captive in the pallet.
  • the identification device is provided with a communication interface which can communicate with external devices, for example via radio waves, it is considered advantageous to accommodate the identification device in a chamber of the pallet, which is largely protected against damage and external harmful influences.
  • a chamber may for example be formed by a honeycomb cell which does not border on an outer wall of the pallet.
  • the honeycomb cell can be arranged in one of the feet or in other honeycomb cells of the lower pallet deck.
  • the identification device can serve to mark the pallet unmistakably in order to be able to record and track these individually.
  • the identification device can be a passive or active device, in the latter case it preferably has its own voltage source, eg a long-term storage battery of high capacity.
  • the identification device then has, for example, a reception module and a transmission module, with which it can be addressed remotely by means of HF and then respond with an acknowledgment signal.
  • This can be served by the existing wireless cell network, which otherwise serves mobile communications.
  • This enables pallet tracking and locating lost pallets or loads by: the radio cell is identified in which the transmission module of the pallet has registered.
  • a GPS receiver can be provided in the identification module, which is activated briefly and reports the position of the pallet via SMS to the central office instead of the acknowledgment signal.
  • the receiving module is turned on only in timed intervals or a predetermined time scheme briefly, eg daily or weekly or according to a given schedule table in each case only a few seconds or minutes.
  • the switch-on time is limited to a short period of time, which is sufficient in view of the adjusting path differences of the system clocks in the center and the range and the expected duration of a call signal through the cellular network to reach the pallet safely.

Abstract

A novel plastic pallet (1) has two decks (2, 9), which are joined to each other by means of only one weld seam (32). The weld seam is preferably situated in a neutral fibre of the pallet (1). In its external dimensions the pallet (1) conforms to conventional EURO pallets. However, it outperforms them in terms of longevity, hygiene and load-bearing capacity. The pallet (1) can incorporate an identification device which stores or keeps at the ready data in machine-readable form and preferably delivers said data on request. For its operation the identification device preferably does not have a battery or a similar energy store which will run down, instead it receives the power for its operation together with a request signal. It allows the creation of a pallet system with individual tracking of the pallets. If the identification device is programmable it can also store and provide upon request data relating to the type, the quantity, the destination or other characteristics of the goods.

Description

Palettepalette
Die Erfindung betrifft eine Palette, insbesondere zum Warentransport .The invention relates to a pallet, in particular for transporting goods.
Für den Transport von Industriegütern wie auch für den Transport von Lebensmitteln werden in großem Maßstab Paletten einheitlicher Abmessungen verwendet, die in der Regel im Rahmen von Pfandsystemen zirkulieren. Die Paletten dienen der Aufnahme der paketierten und verzurrten Waren zum Transport per Gabelstapler, LKW oder Bahn sowie zur Bereithaltung der Waren in Warenlagern. Häufig bestehen solche Paletten im Grunde aus einem Holzrost, der auf entsprechenden Holzfüßen steht. Obwohl sich solche Paletten grundsätzlich bewährt haben ist immer wieder nach Alternativen aus Kunststoff gesucht worden .For the transport of industrial goods as well as for the transport of food, pallets of uniform dimensions are used on a large scale, which usually circulate in the context of deposit systems. The pallets are used to hold the packaged and lashed goods for transport by forklift, truck or train, as well as to store the goods in warehouses. Often such pallets exist in the Basically made of a wooden grid, which stands on corresponding wooden feet. Although such pallets have proven themselves in principle, alternatives to plastic have been sought.
Eine solche alternative, aus Kunststoff bestehende Palette, ist beispielsweise aus dem Gebrauchsmuster G 94 15 328.0 bekannt. Diese Palette weist ein Oberdeck auf, das an seiner Oberseite durch eine ebene geschlossene Fläche abge- schlössen ist. An seiner Unterseite sind Wabenzellen ausgebildet . Zu der Palette gehört außerdem ein Unterdeck, das unten geschlossen und an seiner Oberseite mit Wabenzellen versehen ist. Die beiden Decks sind miteinander flächig verschweißt. Von unten her sind an das Unterdeck Füße an- geschweißt, von denen jeweils drei untereinander durch einen Steg verbunden sind.Such an alternative pallet made of plastic, for example, from the utility model G 94 15 328.0 known. This pallet has an upper deck, closed at its upper side by a flat, closed surface. On its underside honeycomb cells are formed. The pallet also includes a lower deck closed at the bottom and fitted with honeycomb cells at the top. The two decks are welded together flat. From below, feet are welded to the lower deck, three of which are connected to each other by a bridge.
Diese Palette eignet sich als Hygienepalette, insbesondere für den Transport von Lebensmitteln. Jedoch unterliegt sie Einschränkungen hinsichtlich der Belastbarkeit. Wird dieThis pallet is suitable as a hygiene pallet, especially for the transport of food. However, it is subject to restrictions in terms of resilience. Will the
Palette hinsichtlich ihrer äußeren Abmessungen, insbesondere hinsichtlich ihrer Höhe, an vorhandene, der DIN-Vorschrift entsprechende Holzpalettensysteme angeglichen, um in das gleiche Pfandsystem eingegliedert werden zu können, muss mit gegenüber Holzpaletten verminderter Festigkeit gerechnet werden. Des Weiteren ist die Herstellung relativ aufwändig.Pallet in terms of their external dimensions, in particular in terms of their height, adapted to existing, the DIN regulation corresponding wooden pallet systems in order to be incorporated into the same deposit system can be expected with respect to wooden pallets reduced strength. Furthermore, the production is relatively expensive.
Davon ausgehend ist es Aufgabe der Erfindung, eine verbesserte Palette zu schaffen. Insbesondere soll die neu ge- schaffene Palette eine erhöhte mechanische Stabilität aufweisen. Diese Aufgabe wird mit der Palette nach Anspruch 1 gelöst :On this basis, it is an object of the invention to provide an improved range. In particular, the newly created pallet should have increased mechanical stability. This object is achieved with the pallet according to claim 1:
Die erfindungsgemäße Palette weist ein unteres Palet- tendeck auf, an dem Füße einstückig angeformt sind. Das obere Palettendeck und das untere Palettendeck sind miteinander verschweißt. Diese Schweißnaht ist die einzige wesentliche Schweißnaht der Palette. Wenn die Palettendecks aus einem faserverstärkten Kunststoff, vorzugsweise einem langfaser- verstärkten Kunststoff, bestehen, lassen sich somit Paletten erzeugen, die bei gleicher Abmessung wie eine Holzpalette höhere Lasten als diese tragen können. Die Schweißverbindung ist auf die Ebene zwischen den beiden Oberdecks beschränkt . In dieser Ebene stehen die in den Kunststoff eingebetteten Fasern, beispielsweise Glasfasern von 6 bis 25 mm Länge, zunächst einander mit ihren Stirnseiten gegenüber. Bei der Ausbildung der Schweißnaht bilden sich an den Wabenzellen- rändern Wulste, in denen die Fasern miteinander verhakt oder verfilzt sind. Dies ergibt eine sehr belastbare und feste Schweißnaht. Werden die Palettendecks ansonsten im Spritzpressverfahren hergestellt, sind die Fasern im Übrigen wandparallel, d.h. vorwiegend ungefähr parallel zu den Außenseiten und sonstigen Flächen der Decks sowie der Wabenzel- lenwände orientiert. Die mit dem Kunststoff fließenden lan- gen Glasfasern oder sonstigen Fasern legen sich somit auch um Biegungen und Ecken des Kunststoffs herum ohne zu brechen, so dass die angeformten Füße ohne Unterbrechung des Faserverlaufs erzeugt werden. Dies ergibt eine hohe Festigkeit. Im Vergleich dazu ist beim Anschweißen von Füßen an die ebene Unterseite eines Palettendecks kein glasfaserverstärkter Übergang erzielbar, d.h. die Fasern durchqueren die Naht nicht . Die Erfindung hilft hier ab und führt zu einer Bauform, bei der sich die Fasern des Unterdecks -unterbrechungsfrei in die Füße hinein erstrecken.The pallet according to the invention has a lower pallet deck, on which feet are integrally formed. The upper pallet deck and the lower pallet deck are welded together. This weld is the only essential weld on the pallet. If the pallet decks are made of a fiber-reinforced plastic, preferably a long-fiber reinforced plastic, pallets can be produced which, with the same dimensions as a wooden pallet, can carry higher loads than these. The welded joint is limited to the plane between the two upper decks. In this level, the fibers embedded in the plastic, for example glass fibers of 6 to 25 mm in length, initially face each other with their front sides. When the weld is formed, beads form on the honeycomb edges in which the fibers are entangled or matted together. This results in a very strong and strong weld. Incidentally, if the pallet decks are produced by the transfer molding process, the fibers are otherwise wall-parallel, ie oriented predominantly approximately parallel to the outer sides and other surfaces of the decks and the honeycomb cell walls. The long glass fibers or other fibers flowing with the plastic thus also wrap around bends and corners of the plastic without breaking, so that the formed feet are produced without interrupting the course of the fibers. This results in a high strength. In comparison, when welding feet to the flat underside of a pallet deck no glass fiber reinforced transition can be achieved, ie the fibers do not pass through the seam. The invention helps here and leads to a Design in which the fibers of the lower deck - interruption-free extend into the feet.
Die Palettendecks sind miteinander vorzugsweise spie- gelverschweißt. Die Ränder der Wabenzellen werden vollflächig an ihren Stirnseiten erwärmt und gegeneinander gedrückt, so dass es zur Verfilzung der Fasern und Verschwel- ßung der Kunststoffe kommt. Alternativ können andere Schweißverfahren, wie Reibschweißen, Ultraschallschweißen oder auch geeigneten Verklebungen eingesetzt werden.The pallet decks are preferably mirror-welded together. The edges of the honeycomb cells are heated over their entire surface and pressed against each other so that the fibers are entangled and the plastics frayed. Alternatively, other welding methods, such as friction welding, ultrasonic welding or suitable bonding can be used.
Das obere und das untere Palettendeck können aus dem gleichen Kunststoff gefertigt sein. Es ist jedoch auch möglich, die Palettendecks aus unterschiedlichen Kunststoffen zu fertigen. Beispielsweise kann das obere Palettendeck aus einem Primärkunststoff und das untere Palettendeck aus einem Recyclingkunststoff gefertigt sein. Dies ergibt nach oben, d.h. an der der Ware zugewandten Seite, eine hygienische unbedenkliche Oberfläche während das untere Palettendeck mit verminderten Kosten erzeugt werden kann.The upper and lower pallet deck can be made of the same plastic. However, it is also possible to manufacture the pallet decks of different plastics. For example, the upper pallet deck can be made of a primary plastic and the lower pallet deck made of a recycled plastic. This results in an upward, i. on the side facing the goods, a hygienic harmless surface while the lower pallet deck can be produced at a reduced cost.
Unabhängig von der verwendeten Kunststoffart werden bevorzugt langfasergefüllte Kunststoffe bevorzugt . Diese enthalten Glasfasern oder andere Fasern, deren durchschnitt- liehe Faserlänge deutlich größer ist als die Dicke der zu erzeugenden Wände. Mit einem geeigneten Herstellungsverfahren, beispielsweise einem Spritzpressverfahren, lässt sich erreichen, dass sich die Fasern bei dem Herstellungsprozess wandparallel, d.h. parallel zur jeweils benachbarten Fläche ausrichten. Es werden glatten Oberflächen erhalten, aus denen keine Faserenden ragen. Dies wird sowohl aus Sicht der Materialfestigkeit als auch aus Sicht der Oberflächengüte und Hygiene zu bevorzugen. Ein geeignetes Herstellungsver- fahren ist ein Spritzpressverfahren, bei dem zähplastischer, fasergefüllter Kunststoff in eine teilgeschlossene Spritzpressform eingespritzt wird, wonach die Form vollends geschlossen wird. Das Einspritzen in die noch nicht ganz ge- schlossene Form hat den Vorzug, dass sich eine gute Formfüllung erreichen lässt . Der nachfolgende Schließvorgang der Form ähnelt einem Pressvorgang, bei dem durch das Fließen des zähplastischen Kunststoffs die Ausrichtung der Fasern erzielt wird.Regardless of the type of plastic used, preferably long fiber-filled plastics are preferred. These contain glass fibers or other fibers whose average length of fibers is significantly greater than the thickness of the walls to be produced. With a suitable manufacturing method, for example a transfer molding method, it is possible to achieve that the fibers in the production process are aligned parallel to the wall, ie parallel to the respectively adjacent surface. Smooth surfaces are obtained from which no fiber ends protrude. This is to be preferred both from the point of view of material strength and from the point of view of surface quality and hygiene. A suitable manufacturing driving is a transfer molding process in which viscoplastic, fiber-filled plastic is injected into a partially closed injection molding mold, after which the mold is completely closed. The injection into the not yet completely closed form has the advantage that a good mold filling can be achieved. The subsequent closing of the mold is similar to a pressing process, in which the alignment of the fibers is achieved by the flow of the plastic plastic.
Vorzugsweise weisen beide Palettendecks einheitliche und deckungsgleiche Wabenmuster auf. Damit wird erzielt, dass beim Verschweißen der Palettendecks die Ränder der Wabenzellen aufeinander treffen, um eine wulstartige Schweiß- naht auszubilden. Dabei wird vorzugsweise so viel Material seitlich von den Wabenzellenrändern verdrängt, dass sich zwischen den Palettendecks eine nahezu geschlossene Fläche ausbildet. Auf diese Weise wird eine gute Verfilzung der im Kunststoff enthaltenen Fasern im Bereich der Schweißnaht erzielt. Außerdem kann auf diese Weise die Höhe der hergestellten, die Palette bildenden Verbundplatte reguliert werden.Both pallet decks preferably have uniform and congruent honeycomb patterns. This ensures that when welding the pallet decks, the edges of the honeycomb cells meet to form a bead-like weld seam. In this case, preferably as much material is laterally displaced from the honeycomb cell edges that forms an almost closed surface between the pallet decks. In this way, a good entanglement of the fibers contained in the plastic is achieved in the weld region. In addition, in this way, the height of the produced, forming the pallet composite plate can be regulated.
Vorzugsweise weisen die Füße ein Wabenzellenmuster auf, das von dem übrigen Wabenzellenmuster des unteren Palettendecks abweicht. Die Wabenzellen in den Füßen sind vorzugsweise wesentlich größer als die sonstigen Wabenzellen des unteren Palettendecks . Dadurch wird das Ausformen des unteren Palettendecks nach dem Spritzpressvorgang erleichtert.Preferably, the feet have a honeycomb cell pattern that differs from the rest of the honeycomb cell pattern of the lower pallet deck. The honeycomb cells in the feet are preferably much larger than the other honeycomb cells of the lower pallet deck. This facilitates the molding of the lower pallet deck after the transfer molding process.
Weiter wird bevorzugt, dass jeder Fuß einen Zwischenboden aufweist. Dieser ist beispielsweise unterhalb der Mitte der Höhe des Fußes angeordnet. Weiter vorzugsweise liegt dieser Zwischenboden oberhalb von Stegen, die die unteren Enden der Füße miteinander verbinden. Der Zwischenboden gibt den Füßen eine seitliche Steifigkeit, so dass diese auch dann nicht kollabieren, wenn sie unter erheblicher Last ste- hen und beispielsweise mit den Spitzen der Gabel eines Gabelstaplers angestoßen werden. Unterhalb des Zwischenbodens sind vorzugsweise weitere Wabenzellen angeordnet, wobei diese Wabenzellen dann nach unten hin offen sind. Die unteren Wabenzellen unterscheiden sich vorzugsweise von den oberen Wabenzellen. Sie können einen erheblich kleineren Querschnitt aufweisen als die oberen Wabenzellen. Auch dies kann der Festigkeit der Füße zugute kommen. Vorzugsweise liegt der Zwischenboden auf einer Höhe von z.B. 30 bis 70 mm in einem Bereich, der von der Spitze einer am Boden liegenden Gabelstaplergabel üblicherweise getroffen wird.It is further preferred that each foot has an intermediate floor. This is arranged, for example, below the middle of the height of the foot. Further preferably lies This intermediate floor above bars that connect the lower ends of the feet together. The intermediate floor gives the feet lateral rigidity, so that they do not collapse even when they are under considerable load and are pushed, for example, with the tips of the forks of a fork-lift truck. Below the false bottom, further honeycomb cells are preferably arranged, these honeycomb cells then being open towards the bottom. The lower honeycomb cells preferably differ from the upper honeycomb cells. They can have a considerably smaller cross-section than the upper honeycomb cells. This too can benefit the firmness of the feet. Preferably, the intermediate floor is at a height of, for example, 30 to 70 mm in a region which is usually hit by the tip of a fork-lift fork lying on the ground.
Die die Füße verbindenden Stege sind an ihrer Unterseite vorzugsweise mit Rippen versehen. Die zwischen den Rippen vorhandenen Zwischenräume liegen offen. Dies hat den Vorzug, dass die so gebildete Palette einen sicheren Stand auch auf unebenem Boden erhält. Einzelne Kiesel oder sonstige kleinere, auf dem Boden liegende Gegenstände, werden weder in den Boden gedrückt noch führen sie zum Kippeln einer Palette. Vielmehr finden sie sich in den Wabenzellen der Füße oder zwischen den Rippen der Stege ein.The webs connecting the feet are preferably provided with ribs on their underside. The spaces between the ribs are open. This has the advantage that the pallet thus formed gets a secure footing even on uneven ground. Individual pebbles or other smaller objects lying on the floor are neither pressed into the ground nor do they cause a pallet to tip over. Rather, they find themselves in the honeycomb cells of the feet or between the ribs of the webs.
Die aus Kunststoff bestehenden Paletten weisen geschlossene Wabenzellen auf. Außerdem können sie ein Aufnahmefach zur Aufnahme eines manuell optisch oder einen maschi- nenlesbaren Datenträgers aufweisen. Als Aufnahmefach kann eine Wabenzelle dienen. Das Aufnahmefach kann auch in einem mechanisch wenig belasteten, von außen sichtbaren und geschützten Bereich, wie beispielsweise einem Fach angeordnet sein, das an einer Außenseite eines Fußes angeordnet ist. Dieses Fach kann mit einem Sichtfenster versehen sein, wobei es so ausgebildet sein kann, dass manuell lesbare Datenträger, wie beispielsweise Etiketten oder Karten, eingeschoben werden können. Es wird jedoch bevorzugt, maschinenlesbareThe plastic pallets have closed honeycomb cells. In addition, they can have a receiving compartment for receiving a manually optically or a machine-readable data carrier. The receptacle can be a honeycomb cell. The receptacle can also be arranged in a mechanically slightly loaded, visible from the outside and protected area, such as a tray be arranged on an outside of a foot. This compartment can be provided with a viewing window, wherein it can be designed so that manually readable data carriers, such as labels or cards, can be inserted. However, it is preferred machine-readable
Datenträger, wie beispielsweise durch Funkwellen oder sonstige Strahlung auslesbare Chips, in die Palette einzubauen. Solche Identifikationseinrichtungen enthalten in der Regel eine Flachspule und einen an diesen angeschlossenen Chip. Zumindest das Auslesen von Daten, die die Palette identifizieren können, kann durch hochfrequente Radiowellen erfolgen. Solche Identifikationseinrichtungen werden häufig als RF-ID-Einrichtungen bezeichnet.Disk, such as by radio waves or other radiation readable chips to install in the range. Such identification devices usually contain a flat coil and a chip connected thereto. At least the reading of data that can identify the pallet can be done by high frequency radio waves. Such identification devices are often referred to as RF-ID devices.
Diese Einrichtung kann bedarfsweise auch so geschaffen sein, dass Informationen in die Identifikationseinrichtung eingebracht werden können, um beispielsweise die auf der Palette liegende Ware zu kennzeichnen. In einer anderen Variante dient die Identifikationseinrichtung lediglich der unverwechselbaren Kennzeichnung der Palette. Mit beiden Varianten lässt sich eine lokale, regionale oder globale Palettenverfolgung erzielen. Die entsprechenden Identifikationseinrichtungen können in die Paletten unverlierbar eingebaut, beispielsweise in deren Kunststoff eingebettet sein. Dies kann bei der Herstellung der Paletten im Spritzpressverfahren erfolgen. Bedarfsweise können die Identifikations- einrichtungen von einem Mantel umgeben sein, der sie bei der Herstellung vor der Einwirkung zu hoher Temperaturen des zähplastischen Kunststoffs schützt, wenn dieser die Identi- fikationseinrichtung umfließt.If necessary, this device can also be created in such a way that information can be introduced into the identification device in order to identify, for example, the goods lying on the pallet. In another variant, the identification device only serves the distinctive marking of the pallet. Both variants can be used to achieve local, regional or global pallet tracking. The corresponding identification devices can be permanently installed in the pallets, for example embedded in their plastic. This can be done in the production of pallets in the transfer molding process. If required, the identification devices can be surrounded by a jacket, which protects them from being exposed to high temperatures of the viscoplastic during manufacture when it flows around the identification device.
Es ist auch möglich, die Identifikationseinrichtung in eine Wabenzelle, vorzugsweise des unteren Palettendecks, beispielsweise eine außen liegende Wabenzelle eines Palettenfußes einzulegen, bevor das untere Palettendeck mit dem oberen Palettendeck verschweißt wird. Die Identifikationseinrichtung kann in der Wabenzelle durch Schaum oder andere geeigneten Halteeinrichtung am Platz gesichert werden, um sie beispielsweise an der Außenseite zu halten. Auch in diesem Fall ist die Identifikationseinrichtung in der Palette unverlierbar gehalten.It is also possible, the identification device in a honeycomb cell, preferably the lower pallet deck, For example, insert an external honeycomb cell of a pallet foot before the lower pallet deck is welded to the upper pallet deck. The identification device can be secured in place in the honeycomb cell by foam or other suitable holding means in place, for example to keep it on the outside. Also in this case, the identification device is held captive in the pallet.
Wenn die Identifikationseinrichtung mit einer Kommunikationsschnittstelle versehen ist, die beispielsweise über Funkwellen mit äußeren Geräten kommunizieren kann, wird es als vorteilhaft angesehen, die Identifikationseinrichtung in einer Kammer der Palette unterzubringen, die vor Beschädi- gungen und äußeren schädlichen Einflüssen weitgehend geschützt ist. Eine solche Kammer kann beispielsweise durch eine Wabenzelle gebildet sein, die nicht an eine Außenwand der Palette grenzt . Die Wabenzelle kann in einem der Füße oder auch in sonstigen Wabenzellen des unteren Palettendecks angeordnet sein. Die Identifikationseinrichtung kann dazu dienen, die Palette unverwechselbar zu kennzeichnen, um diese individuell erfassen und verfolgen zu können.If the identification device is provided with a communication interface which can communicate with external devices, for example via radio waves, it is considered advantageous to accommodate the identification device in a chamber of the pallet, which is largely protected against damage and external harmful influences. Such a chamber may for example be formed by a honeycomb cell which does not border on an outer wall of the pallet. The honeycomb cell can be arranged in one of the feet or in other honeycomb cells of the lower pallet deck. The identification device can serve to mark the pallet unmistakably in order to be able to record and track these individually.
Die Identifikationseinrichtung kann eine passive oder aktive Einrichtung sein, in letzterem Fall verfügt sie vorzugsweise über eine eigene Spannungsquelle, z.B. eine lang- zeitspeichernde Batterie hoher Kapazität. Die Identifikationseinrichtung verfügt dann z.B. über ein Empfangsmodul und ein Sendemodul, mit denen es aus der Ferne mittels HF ansprechbar ist und dann mit einem Quittungssignal antwortet. Dazu kann das sonst dem Mobilfunk dienende vorhandene Funkzellennetz dienen. Damit ist eine Palettenverfolgung und eine Ortung verlorener Paletten oder Ladungen möglich, indem die Funkzelle identifiziert wird, in der sich das Sendemodul der Palette angemeldet hat . Bei einer besonders komfortablen Variante kann in dem Identifikationsmodul ein GPS-Empfänger vorgesehen sein, der kurz aktiviert wird und anstelle des Quittungssignals die Position der Palette über SMS an die Zentralstelle meldet. Zur Sicherstellung der Funktion über lange Zeiträume von mehreren Jahren und batterieschonendsten Betrieb ist es möglich, das Empfangsmodul nur in zeitlich vorgegebenen Zeitabständen oder nach einem vorgegebenen Zeitschema kurzzeitig einzuschalten, z.B. täglich oder wöchentlich oder nach vorgegebener Zeitplantabelle jeweils lediglich einige Sekunden oder Minuten. Die Einschaltzeit wird auf eine kurze Zeitspanne begrenzt, die angesichts der sich einstellenden Gangunterschiede der Systemuhren in der Zentrale und der Palette sowie der zu erwartenden Laufzeit eines Rufsignals durch das Funkzellennetz ausreicht um die Palette sicher zu erreichen. Das Sendemodul wird nur bei Empfang eines Rufsignals kurz eingeschaltet. Ansonsten läuft nur eine energiesparende Systemuhr. In der Zentrale werden verlorene Paletten angefragt, wobei das Rufsignal nur innerhalb der Zeitfenster ausgesandt wird, in denen der Palettenempfänger aktiv ist. Es kann vorgesehen werden, dass unterschiedliche Paletten einer Serie nach unterschiedlichen Zeitschemata oder Zeittabellen und somit zu unterschiedli- chen Zeitpunkten aktiv werden und auf Empfang gehen. Sind mehrere Paletten einer Serie, z.B. einer gemeinsamen Ladung verloren gegangen, wird dadurch die Ortung erleichtert und beschleunigt. Die Zentrale, in der die Empfangszeitpläne aller Paletten hinterlegt sind, ruft zur Auffindung der ver- lorengegengenen Ladung oder Paletten zunächst diejenige Palette, die den nächstliegenden EmpfangsZeitpunkt aufweist, und danach eine oder mehrere oder alle anderen in der Reihenfolge ihrer EmpfangsZeitpunkte. Es ist zur Diebstahlsicherung auch möglich, die Identifikationseinrichtung mit einer Timereinrichtung zu versehen. Der Timer wird beim Warenausgang z.B. mittels eines HF-Signals aktiviert und auf eine Zeit eingestellt, die etwas grö- ßer als die zu erwartende Reisezeit ist. Am Empfangsort wird der Timer mittels eines HF-Signals deaktiviert. Kommt die Palette nicht rechtzeitig am Empfangsort an, loggt sich das Sendemodul in eine Funkzelle ein. Durch Ermittlung der Funkzellen, in denen sich die Palette auf ihrem weiteren Weg jeweils anmeldet, kann der Weg der Palette verfolgt werden. Es ist auch möglich, an der Palette eine GPS-Einheit vorzusehen, die nach Ablauf der Timerzeit aktiviert wird und dann eine Positionsbestimmung durchführt. Die Positionen werden dann z.B. in gegeben Zeitabständen von z.B. 10 min per SMS an die Zentrale durchgegeben. Bei mehreren Paletten können unterschiedliche SMS-Wiederholzeiten oder unterschiedliche Timerzeiten benutzt werden. Letzteres wird erreicht, indem jede Palette ihren individuellen Timeroffset aufweist - d.h. einen individuellen Zeitversatz, der automa- tisch zu der eingegebenen, Timerzeit hinzuaddiert wird. Dadurch senden die Identifikationseinrichtungen der unterschiedlichen Paletten zu unterschiedlichen Zeitpunkten, was die Verfolgung erleichtert und das Funkzellennetz entlastet.The identification device can be a passive or active device, in the latter case it preferably has its own voltage source, eg a long-term storage battery of high capacity. The identification device then has, for example, a reception module and a transmission module, with which it can be addressed remotely by means of HF and then respond with an acknowledgment signal. This can be served by the existing wireless cell network, which otherwise serves mobile communications. This enables pallet tracking and locating lost pallets or loads by: the radio cell is identified in which the transmission module of the pallet has registered. In a particularly convenient variant, a GPS receiver can be provided in the identification module, which is activated briefly and reports the position of the pallet via SMS to the central office instead of the acknowledgment signal. To ensure the function over long periods of several years and battery-saving operation, it is possible to turn on the receiving module only in timed intervals or a predetermined time scheme briefly, eg daily or weekly or according to a given schedule table in each case only a few seconds or minutes. The switch-on time is limited to a short period of time, which is sufficient in view of the adjusting path differences of the system clocks in the center and the range and the expected duration of a call signal through the cellular network to reach the pallet safely. The transmitter module is only briefly switched on when a call signal is received. Otherwise, only an energy-saving system clock is running. In the central office, lost pallets are requested, the call signal being sent only within the time windows in which the pallet receiver is active. It can be provided that different pallets of a series become active and receive at different times according to different time schedules or time tables and thus at different times. If several pallets of a series have been lost, for example, a common load, the location is facilitated and accelerated. The central office, where the reception schedules of all the pallets are stored, first retrieves the pallet with the closest receiving time, and then one or more or all others in the order of their reception times in order to find the lost counterpart or pallet. It is also possible for theft protection to provide the identification device with a timer device. The timer is activated during goods issue eg by means of an RF signal and set to a time that is slightly larger than the expected travel time. At the receiving location, the timer is deactivated by means of an RF signal. If the pallet does not arrive in time at the receiving location, the transmitter module logs into a radio cell. The path of the pallet can be tracked by determining the radio cells in which the pallet logs in each case on their further journey. It is also possible to provide on the pallet a GPS unit, which is activated after the timer time and then performs a position determination. The positions are then sent, for example, in given time intervals of eg 10 minutes by SMS to the central office. With several pallets different SMS repeat times or different timer times can be used. The latter is achieved by each pallet having its own individual timer offset - ie an individual time offset that is automatically added to the entered timer time. As a result, the identification devices of the different pallets send at different times, which facilitates the tracking and relieves the cell network.
Die Palette weist vorzugsweise Funktionsmaße auf, die den DIN-Vorschriften für Holzpaletten entsprechen. Sie können somit in bestehende Palettensysteme integriert werden. Aufgrund ihrer erfindungsgemäßen Bauform weisen sie eine Belastbarkeit auf, die gleich oder größer als die Belastbar- keit von Holzpaletten' ist . Weitere Einzelheiten vorteilhafter Ausführungsformen der Erfindung ergeben sich aus der Zeichnung, der Beschreibung oder aus Ansprüchen.The pallet preferably has functional dimensions that comply with the DIN regulations for wooden pallets. They can thus be integrated into existing pallet systems. Due to its design according to the invention, they have a load capacity which is equal to or greater than the load capacity of wooden pallets'. Further details of advantageous embodiments of the invention will become apparent from the drawings, the description or claims.

In Figur 1 ist eine Palette 1 veranschaulicht, die zur Aufnahme von Waren, zu deren Lagerung und Transport dient. Die Palette 1 weist ein oberes Palettendeck 2 auf, das an seiner Oberseite 3 eine ebene geschlossene Fläche aufweist . Die Oberseite 3 ist unterbrechungsfrei ausgebildet, d.h. vorzugsweise von keinerlei Öffnungen durchbrochen. An dem Rand des oberen Palettendecks 2 können flache nach oben aufragende Stege oder Rippen 4 vorgesehen sein, um ein Herunterrutschen von auf der Oberseite 3 gelagerten Waren zu un- terbinden. Das obere Palettendeck weist, wie aus Figur 3 hervorgeht, an seiner Unterseite 5 mehrere Wabenzellen 6 auf, die von Wänden 7 umgeben sind. Die Wände 7 sind einstückig an das Palettendeck 2 angeformt . Sie weisen eine Dicke auf, die im Wesentlichen mit der Dicke der die Ober- seite 3 festlegenden Wand übereinstimmt . Die Breite der Wabenzellen 6, d.h. der größte Abstand der Wände 7 voneinander, ist vorzugsweise größer als die Tiefe der Wabenzellen 6, d.h. die Länge der Wände 7. Damit lässt sich das Gewicht des oberen Palettendecks 2 gering halten. Die Wände 7 stehen rechtwinklig zu der Oberseite 3 und ihre Ränder 8 liegen in einer gemeinsamen Ebene .In Figure 1, a pallet 1 is illustrated, which serves for receiving goods, for their storage and transport. The pallet 1 has an upper pallet deck 2, which has a flat closed surface on its upper side 3. The top 3 is formed without interruption, i. preferably not pierced by any openings. At the edge of the upper pallet deck 2, flat upwardly projecting webs or ribs 4 may be provided in order to prevent slipping of goods stored on the upper side 3. The upper pallet deck, as shown in FIG. 3, has on its lower side 5 a plurality of honeycomb cells 6, which are surrounded by walls 7. The walls 7 are integrally formed on the pallet deck 2. They have a thickness which substantially coincides with the thickness of the wall defining the upper side 3. The width of the honeycomb cells 6, i. the maximum distance of the walls 7 from each other is preferably greater than the depth of the honeycomb cells 6, i. the length of the walls 7. Thus, the weight of the upper pallet deck 2 can be kept low. The walls 7 are perpendicular to the top 3 and their edges 8 lie in a common plane.
Zu der Palette 1 gehört außerdem ein unteres Palettendeck 9, das, wie auch das obere Palettendeck 2, einstückig, d.h. als durchgehendes einteiliges, Kunststoffteil ausgebildet ist . Es weist einen im Wesentlichen plattenartigen oberen Abschnitt 11 auf, der unten mit einer geschlossenen Fläche 12 versehen ist. Diese ebene Fläche ist parallel zu der Oberseite 3 orientiert und wird von einer Wand 13 ge- bildet, von der Wände 14 senkrecht aufragen. Diese umgrenzenAlso included in the pallet 1 is a lower pallet deck 9, which, like the upper pallet deck 2, is in one piece, i. as a continuous one-piece, plastic part is formed. It has a substantially plate-like upper portion 11, which is provided at the bottom with a closed surface 12. This flat surface is oriented parallel to the upper side 3 and is formed by a wall 13, from which walls 14 project vertically. These outline
Wabenzellen 15, die mit den oberen Wabenzellen 6 deckungsgleich sind. Somit liegen ihre Ränder 16 den Rändern 8 des oberen Palettendecks 2 fluchtend gegenüber. Zu dem unteren Palettendeck 9 gehören Füße 17, 18, 19, die sich unterhalb der Wand 3 nach unten erstrecken. Die Füße 17, 18, 19 sind einstückiger Bestandteil des unteren Palettendecks 9 und mit diesem in einem gemeinsamen Spritz- pressvorgang hergestellt. Sie weisen eine Höhe von z.B. 120 mm auf während die Gesamthöhe der Palette, abgesehen von den Stegen 4, vorzugsweise etwa 145 mm beträgt. Die Füße 17, 18, 19 sind, wie Figur 3 am Beispiel des Fußes 17 erkennen lässt, jeweils mit einer Innenstruktur versehen, die obere und untere Wabenzellen 21, 22 unterscheidet. Zwischen denHoneycomb cells 15, which are congruent with the upper honeycomb cells 6. Thus, their edges 16 are the edges 8 of the upper pallet deck 2 in alignment. To the lower pallet deck 9 include feet 17, 18, 19, which extend below the wall 3 down. The feet 17, 18, 19 are an integral part of the lower pallet deck 9 and made with this in a common injection molding process. They have a height of eg 120 mm while the total height of the pallet, apart from the webs 4, is preferably about 145 mm. The feet 17, 18, 19 are, as shown in FIG. 3 using the example of the foot 17, each provided with an internal structure which distinguishes between upper and lower honeycomb cells 21, 22. Between
Wabenzellen 21, 22 ist ein Zwischenboden 23 ausgebildet, der vorzugsweise etwa parallel zu der Wand 13 orientiert ist. Er ist jedoch in der Höhe deutlich gegen die Wand 13 versetzt, wobei er vorzugsweise unterhalb der mittleren Höhe des Fußes 17 angeordnet ist. Er kann bedarfsweise auch etwa auf mittlerer Höhe des Fußes stehen, d.h. auf einer Höhe zwischen 50 und 70 mm, gerechnet vom unteren Rand 24 des Fußes 17.Honeycomb cells 21, 22 is an intermediate bottom 23 is formed, which is preferably oriented approximately parallel to the wall 13. However, it is offset significantly in height against the wall 13, wherein it is preferably located below the mean height of the foot 17. If necessary, it can also be located approximately at mid-height of the foot, i. at a height between 50 and 70 mm, calculated from the lower edge 24 of the foot 17.
Die Wabenzellen 21 sind beispielsweise aus Figur 4 er- sichtlich. Sie weichen in ihrer Form und Größe deutlich von den sonstigen Wabenzellen 15 ab, die die Wand 13 außerhalb der Füße 17, 18, 19 bedecken. Wie dargestellt, können diese Wabenzellen 15 ein regelmäßiges Dreieckmuster bilden. Es ist jedoch auch möglich, andere Wabenzellenformen, wie bei- spielsweise Vierecke oder Sechsecke zu verwenden. Die Dreiecksform hat sich jedoch aus schweißtechnischer Sicht als vorteilhaft herausgestellt, wie an späterer Stelle erläutert wird. Die Wabenzellen 21 des Fußes 17 weisen jeweils wesentlich größere Querschnitte auf als die Wabenzellen 15. Des Weiteren weichen sie von dem übrigen Muster ab. Vorzugsweise ist der Fuß 17 rechteckig berindet. Die das Rechteck (mit abgerundeten Ecken) definierenden Außenwände sind mit 25 bezeichnet. Etwa mittig steht in dem Fuß 17 eine hohlzylin- drische bzw. im Horizontalschnitt kreisförmige Wand 26, von der sich strahlenförmig weitere Wände zu den Ecken des rechteckigen Fußes 17 erstrecken. Diese Wände erreichen das Zentrum des von der Wand 26 festgelegten Kreises nicht. Wei- tere rechtwinklig zueinander orientierte Wände 27 erstrecken sich zu den Mitten der Kanten des von der Wand 25 festgelegten Rechtecks und kreuzen sich im Zentrum des von der Wand 26 festgelegten Kreises. Somit sind in dem Fuß 17 relativ große Wabenzellen 21 ausgebildet. ' • The honeycomb cells 21 can be seen, for example, from FIG. They differ in their shape and size significantly from the other honeycomb cells 15, which cover the wall 13 outside of the feet 17, 18, 19. As shown, these honeycomb cells 15 can form a regular triangular pattern. However, it is also possible to use other honeycomb cell shapes, such as quadrilaterals or hexagons. However, the triangular shape has been found to be advantageous from a welding point of view, as will be explained later. The honeycomb cells 21 of the foot 17 each have substantially larger cross-sections than the honeycomb cells 15. Furthermore, they deviate from the rest of the pattern. Preferably, the foot 17 is rectangular berindet. The rectangle (with rounded corners) defining outer walls are designated 25. Approximately in the center is in the foot 17 a hollow cylinder drische or in the horizontal section circular wall 26, from which radiate further walls to the corners of the rectangular foot 17 extend. These walls do not reach the center of the circle defined by the wall 26. Further walls 27 oriented at right angles to one another extend to the centers of the edges of the rectangle defined by the wall 25 and intersect in the center of the circle defined by the wall 26. Thus, 17 relatively large honeycomb cells 21 are formed in the foot. '•
Die unteren Wabenzellen 22 weisen eine abweichende, beispielsweise aus Figur 5 oder Figur 2, hervorgehende Form auf. Die ringförmige Wand 26 ist mit gleichem Durchmesser wie oberhalb auch unterhalb des Zwischenbodens 23 vorhanden. Ebenso sind die sich zu den Ecken des von der äußeren Wand 25 beschriebenen Rechtecks erstreckende Wände vorhanden. Parallel zu den Wänden 27 erstrecken sich jedoch in höherer Anzahl, z.B. 2 bis 6, weitere stegartige Wände, durch den von dem Fuß 17 umschlossenen Innenraum.The lower honeycomb cells 22 have a different shape, for example from FIG. 5 or FIG. 2. The annular wall 26 is present with the same diameter as above also below the intermediate bottom 23. Likewise, the walls extending to the corners of the rectangle described by the outer wall 25 are present. However, in parallel with the walls 27, a larger number, e.g. 2 to 6, more web-like walls, by the enclosed by the foot 17 interior.
Die Füße 17, 18, 19 sind untereinander durch Verbindungsstege 28 verbunden, die nach oben hin glatt geschlossen und unten mit Rippen 29 versehen sind. Die obere äußere Form der Stege 28 geht insbesondere aus Figur 1 hervor. Sie kön- nen seitlich angeschrägt sein, um Beschädigungen zu vermeiden und das Einfädeln von Gabeln eines Gabelstaplers zu ermöglichen und zu erleichtern. Die Rippen 29 erstrecken sich parallel zueinander in Längsrichtung der Verbindungsstege 28 und dabei mit senkrechter Orientierung von Fuß zu Fuß (17 zu 18, 18 zu 19) . Die unteren Ränder der Rippen 29 liegen mit dem Rand 24 in einer gemeinsamen Ebene, die die Unterseite der Palette 1 markiert. Das obere Palettendeck 2 und das untere Palettendeck 9 sind vorzugsweise im Spritzpressverfahren aus einem Kunststoff mit starker Faserfüllung hergestellt. Die Faserfüllung kann einen sehr hohen Anteil des Werkstoffs ausmachen, der beispielsweise 30% beträgt. Der Werkstoff kann Recyclingkunststoff oder Primärkunststoff sein. Zumindest für das obere Palettendeck 2 wird vorzugsweise Primärkunststoff verwendet während für das untere Palettendeck 9 auch Recyclingkunststoff in Frage kommt. Die Palettendecks 2, 9 weisen durchgehend eine einheitliche Wandstärke von z.B. 2 bis 3 mm auf. Die in den Kunststoff eingebetteten Fasern, beispielsweise Glasfasern 31, weisen eine Länge auf, die größer ist als die Stärke d.h. Dicke der Wände. In Folge der Herstellung der Palettendecks 2, 9 im Spritzpressverfahren sind die Fasern 31, wie Figur 6 erkennen lässt, vorzugsweise im Wesentlichen parallel zu den Wänden orientiert. Im Spritzprägeverfahren oder Spritzpressverfahren wird eine zähplastische, mit Langfasern gefüllte KunstStoffmassen in eine auf 8 bis 10 mm geschlossene Form durch große Düsen eingefüllt, so dass die in dem Kunststoff enthaltenen Fasern nicht brechen. Sodann wird die Form geschlossen, so dass nur ein Zwischenraum von 2 bis 3 mm (Wandstärke) offen bleibt, wobei sich die Fasern 31 in dem nun stattfindenden Fließvorgang wandparallel orientieren und aus den Oberflächen des Werkstücks nicht heraus ragen.The feet 17, 18, 19 are interconnected by connecting webs 28, which are closed at the top smooth and bottom with ribs 29 are provided. The upper outer shape of the webs 28 is apparent in particular from Figure 1. They can be bevelled sideways to prevent damage and to facilitate and facilitate the threading of forks of a forklift truck. The ribs 29 extend parallel to each other in the longitudinal direction of the connecting webs 28 and thereby with vertical orientation from foot to foot (17 to 18, 18 to 19). The lower edges of the ribs 29 lie with the edge 24 in a common plane which marks the underside of the pallet 1. The upper pallet deck 2 and the lower pallet deck 9 are preferably made by injection molding of a plastic with a strong fiber filling. The fiber filling can account for a very high proportion of the material, which is for example 30%. The material can be recycled plastic or primary plastic. At least for the upper pallet deck 2 preferably primary plastic is used while for the lower pallet deck 9 also recycled plastic comes into question. The pallet decks 2, 9 consistently have a uniform wall thickness of eg 2 to 3 mm. The embedded in the plastic fibers, such as glass fibers 31, have a length which is greater than the thickness ie thickness of the walls. As a result of the manufacture of the pallet decks 2, 9 in the transfer molding process, the fibers 31, as shown in FIG. 6, are preferably oriented essentially parallel to the walls. In the injection-compression molding or transfer molding process, a viscoplastic, filled with long fibers KunstStoffmassen is filled in a closed to 8 to 10 mm mold by large nozzles, so that the fibers contained in the plastic do not break. Then the mold is closed so that only a gap of 2 to 3 mm (wall thickness) remains open, with the fibers 31 orienting in the flow process now taking place parallel to the wall and not projecting out of the surfaces of the workpiece.
Das obere Palettendeck 2 und das untere Palettendeck 9 werden dann in einem Schweißvorgang miteinander verbunden. Die sich ausbildende Schweißnaht 32 ist aus Figur 6 ersicht- lieh. Sie wird erzeugt, indem die Ränder 8, 16 erwärmt und dann gegen einander gedrückt werden. Dies kann beispielsweise in einem so genannten Spiegelschweißverfahren geschehen. Die erwärmten und somit erweichten Ränder 8, 16 werden dabei gestaucht, wobei sie seitlich ausweichen und dabei eine Wulst bilden. Innerhalb dieser Wulst sind die Fasern 31 durch den plastischen Fließvorgang seitlich ausgelenkt und sie bilden in der Schweißebene eine filz- oder vliesartige Schicht. Die sich ausbildende Wulst kann so groß sein, dass sie die obere und untere Wabenzelle 6, 15 jeweils fast schließt. Durch die in dieser Schweißnaht 32 auftretende Verhakung und Verfilzung der Fasern 31 und das Verschmelzen des Kunststoffs wird eine großflächige und gute Verbindung zwischen den Palettendecks 2, 9 erhalten. Dabei ist die Verbindung ganzflächig. Die Ränder 8 stimmen in ihrem Muster mit den Rändern 16 überein, so dass alle Ränder 8 mit allen Rändern 16 verbunden sind. Außerdem ist die Palette somit ringsum geschlossen.The upper pallet deck 2 and the lower pallet deck 9 are then connected together in a welding process. The forming weld seam 32 is evident from FIG. It is created by heating the edges 8, 16 and then pressing them against each other. This can be done for example in a so-called mirror welding process. The heated and thus softened edges 8, 16 become while compressed, while they dodge sideways and thereby form a bead. Within this bead, the fibers 31 are laterally deflected by the plastic flow and they form a felt or fleece-like layer in the welding plane. The forming bead can be so large that it nearly closes the upper and lower honeycomb cells 6, 15, respectively. By occurring in this weld 32 entanglement and felting of the fibers 31 and the melting of the plastic, a large area and good connection between the pallet decks 2, 9 is obtained. The connection is over the entire surface. The edges 8 in their pattern coincide with the edges 16, so that all the edges 8 are connected to all edges 16. In addition, the pallet is thus closed all around.
Im Bereich der Füße 17, 18, 19 stimmen das Muster der oberen Wabenzellen 6 und das Muster der Wabenzellen 21 miteinander nicht überein. Hier treffen die Ränder 8 nur punktuell auf die oberen Ränder der die Wabenzellen 21 umge- benden Wände. Figur 4 veranschaulicht die Lage der Wabenzellen des oberen Palettendecks 2 punktiert. Einige Schweißpunkte 33 sind gesondert markiert. Es sind dies die Kreuzungspunkte zwischen dem Muster der oberen Wabenzellen 6 und den Wänden der Wabenzellen 21. Es hat sich gezeigt, dass in den Schweißpunkten 33 eine besonders innige Verbindung zwischen den Fasern 31 auftritt.In the region of the feet 17, 18, 19, the pattern of the upper honeycomb cells 6 and the pattern of the honeycomb cells 21 do not coincide with each other. Here the edges 8 meet only at certain points on the upper edges of the walls surrounding the honeycomb cells 21. Figure 4 illustrates the position of the honeycomb cells of the upper pallet deck 2 dotted. Some welds 33 are marked separately. These are the points of intersection between the pattern of the upper honeycomb cells 6 and the walls of the honeycomb cells 21. It has been found that a particularly intimate connection between the fibers 31 occurs in the welding points 33.
Die insoweit beschriebene, mit Glasfasern von 3 bis 40 mm Länge gefüllte Palette, die aus 60 bis 70 % Kunststoff und 30 bis 40 % Langfasern aus Glas oder ähnlichem besteht kann bei den angegebenen Höhen und ansonsten üblicher Palet- tengrδße von beispielsweise 1200 mm x 800 mm eine Last von 800 bis 2000 kg tragen. Sie eignet sich somit uneinge- schränkt zur Integration in bestehende Palettensysteme, wobei sie sich durch Robustheit, Langlebigkeit, hygienische Oberflächen, Festigkeit und sicheren Stand auszeichnet.The described so far, filled with glass fibers of 3 to 40 mm in length pallet, which consists of 60 to 70% plastic and 30 to 40% long fibers of glass or the like can at the indicated heights and otherwise usual Paletten- tengrδße, for example, 1200 mm x 800 mm carry a load of 800 to 2000 kg. It is thus suitable restricts integration into existing pallet systems, with robustness, durability, hygienic surfaces, strength and stability.
Die Figuren 7 und 8 veranschaulichen Weiterbildungen der insoweit beschriebenen Palette 1. Diese Weiterbildungen beruhen auf der Integration einer Identifikationseinrichtung 34 in die Palette 1. Die Identifikationseinrichtung 34 ist vorzugsweise unverlierbar an der Palette 1 angebracht. Z.B. kann die Identifikationseinrichtung 34 durch eine elektrische oder elektronische Einrichtung gebildet sein, die über elektromagnetische Felder mit einer äußeren Abfrageeinrichtung Wechsel wirken kann. Solche Systeme sind beispielsweise als RF-ID-Systeme bekannt. Die Identifikationseinrichtung 34 enthält dazu eine nicht weiter veranschaulichte Kommunikationseinrichtung, beispielsweise mit einer Flachspule und einem an diese angeschlossenen Chip. Über die Flachspule kann die Identifikationseinrichtung 34 mit Energie versorgt werden und es kann auch der Datenaustausch über diese Flach- spule laufen. Es ist möglich, die Identifikationseinrichtung 34 von Hause aus mit einem Code zu versehen, der innerhalb des Palettensystems einmalig ist und die Palette somit individuell kennzeichnet. Dieser Code ist im einfachsten Falle unveränderbar. Es ist auch möglich, die Identifikationsein- richtung 34 so auszulegen, dass dieser Code von außen beispielsweise durch ein entsprechendes Funksignal geändert und somit programmiert werden kann. Dies kann den gesamten Code oder Teile desselben betreffen, so dass der Palette beispielsweise Zusatzinformationen mitgegeben werden können.FIGS. 7 and 8 illustrate further developments of the pallet 1 described so far. These refinements are based on the integration of an identification device 34 in the pallet 1. The identification device 34 is preferably attached captively to the pallet 1. For example, For example, the identification device 34 may be formed by an electrical or electronic device which can act via electromagnetic fields with an external interrogator change. Such systems are known, for example, as RF-ID systems. The identification device 34 includes a not further illustrated communication device, for example, with a flat coil and a chip connected to this. The identification device 34 can be supplied with energy via the flat coil and the data exchange can also run via this flat coil. It is possible to provide the identification device 34 with a code which is unique within the pallet system and thus identifies the pallet individually. This code is unchangeable in the simplest case. It is also possible to design the identification device 34 in such a way that this code can be changed externally, for example by a corresponding radio signal, and thus programmed. This can affect the entire code or parts thereof, so that the pallet can be given additional information, for example.
Die Identifikationseinrichtung 34 ist vorzugsweise in einer nach außen ganz geschlossenen Kammer 35 der Palette 1 angeordnet. Es kann sich dabei um eine gesondert vorgesehe- ne, beispielsweise im Horizontalschnitt rechteckige oder auch um eine sonstige Kammer der Palette 1 handeln. Beispielsweise können die Wabenzellen 6, 15 oder 21 zur Aufnahme der entsprechenden Identifikationseinrichtung 34 die- nen. In den Ausführungsbeispielen nach den Figuren 7 und 8 dienen Wabenzellen 21 des Fußes 17 zur Aufnahme der Identifikationseinrichtung. Sie kann dort, wie Figur 8 veranschaulicht, in einer randfernen inneren Wabenzelle angeordnet und beispielsweise durch ein Schaumpaket 36 am Platz gesichert sein. Die Identifikationseinrichtung 34 kann auch durch sonstige Vergussmasse in der Kammer 35 gesichert sein, lose in der Kammer 35 liegen oder durch ein Schaustoffklemmstück 37 am Platz gesichert sein, wie es in Figur 7 veranschaulicht ist.The identification device 34 is preferably arranged in an outwardly completely closed chamber 35 of the pallet 1. It may be a separate ne, for example, in horizontal section rectangular or act on another chamber of the pallet 1. For example, the honeycomb cells 6, 15 or 21 can serve for receiving the corresponding identification device 34. In the exemplary embodiments according to FIGS. 7 and 8, honeycomb cells 21 of the foot 17 serve to receive the identification device. As can be seen in FIG. 8, it can be arranged in an inner honeycomb cell remote from the edge and secured in place, for example, by a foam packet 36. The identification device 34 may also be secured by other potting compound in the chamber 35, loose in the chamber 35 or be secured by a Schaustoffklemmstück 37 in place, as illustrated in Figure 7.
Die Identifikationseinrichtung 34 kann in einem randnahen Fuß 17 angeordnet sein. Es ist jedoch auch vorgesehen, dass die Identifikationseinrichtung 34 in dem lediglich in Figur 2 sichtbaren mittleren Fuß 18 angeordnet ist. Diese Anordnung hat den Vorzug, dass die Sendeweite nach allenThe identification device 34 may be arranged in a foot 17 near the edge. However, it is also envisaged that the identification device 34 is arranged in the middle foot 18 visible only in FIG. This arrangement has the advantage that the transmission distance to all
Richtungen gleich groß ist und dass die Identifikationseinrichtung 34 in dem mittleren Fuß besonders gut geschützt ist .Directions is the same size and that the identification device 34 is particularly well protected in the middle foot.
Die Identifikationseinrichtung 34 kann, wenn sie besonders robust ist, schon beim Spritzpressen in die Palette eingebracht werden, beispielsweise indem sie in den Kunststoff eingelegt wird. Sie liegt dann nicht in einer Wabenzelle sondern in einer Wand. Soll sie von einer Wabenzelle aufgenommen werden, wird sie nach dem Herstellen des Palettendecks 2 oder 9 in eine Wabenzelle desselben eingelegt. Mit dem Verschweißen der Palettendecks 2, 9 miteinander ist die Kammer, die die Identifikationseinrichtung 34 aufnimmt, hermetisch versiegelt und somit von äußeren schädlichen Einflüssen geschützt an der Palette 1 geschützt.If it is particularly robust, the identification device 34 can already be introduced into the pallet during transfer molding, for example by being inserted into the plastic. It is then not in a honeycomb cell but in a wall. If it is to be taken up by a honeycomb cell, it is inserted into a honeycomb cell after the pallet deck 2 or 9 has been produced. When the pallet decks 2, 9 are welded together, the chamber which receives the identification device 34 is hermetically sealed and thus protected from external harmful influences on the pallet 1 protected.
Eine neuartige Kunststoffpalette 1 weist zwei Decks 2, 9 auf, die lediglich durch eine einzige Schweißnaht 32 miteinander verbunden sind. Die Schweißnaht liegt vorzugsweise in einer neutralen Faser der Palette 1. In ihren äußeren Abmessungen stimmt die Palette 1 mit herkömmlichen EURO-Pa- letten überein. Sie übertrifft diese jedoch hinsichtlich der Langlebigkeit, Hygiene und Lasttragfähigkeit. In die Palette 1 kann eine Identifikationseinrichtung 34 eingearbeitet sein, die Daten in maschinenlesbarer Form speichert oder bereithält und vorzugsweise auf Abruf abgibt. Die Identifikationseinrichtung 34 weist zu ihrem Betrieb vorzugsweise keine Batterie oder dergleichen verschleißende Energiespeicher auf sondern empfängt die Betriebsenergie zusammen mit einem Abfragesignal. Sie ermöglicht den Aufbau eines Palettensystems mit einer Individualverfolgung der Paletten. Ist die Identifikationseinrichtung 34 programmierbar kann sie außerdem Daten übernehmen und auf Abruf abgeben, die dieA novel plastic pallet 1 has two decks 2, 9, which are interconnected only by a single weld 32. The weld seam is preferably in a neutral fiber of the pallet 1. In its outer dimensions, the pallet 1 is consistent with conventional EURO pallets. However, it exceeds them in terms of longevity, hygiene and load capacity. In the pallet 1, an identification device 34 may be incorporated, which stores or holds data in machine-readable form and preferably outputs on demand. The identification device 34 preferably has no battery or the like wear-consuming energy storage for its operation but receives the operating energy together with an interrogation signal. It enables the construction of a pallet system with an individual tracking of the pallets. If the identification device 34 is programmable, it can also take over data and submit it on demand, which is the
