Abstract
Description
Stapelbare Transportpalette aus span-, faser-, pulver- oderStackable transport pallet made of chip, fiber, powder or
granu lotförm gen Roh- bzw. Sekundärrohstoffen.granular raw or secondary raw materials.
Die Erfindung betrifft einstückig gefertigte, stapelbare Transportpaletten hoher statischer und dynamischer Festigkeit und hoher Witterungsbeständigkeit aus span-, faser-, pulver- oder granulatförmigen Roh- bzw. Sekundärrohstoffen, ggf.in Kombination, die mit einem Bindemittel versehen sind und vorzugsweise warm verpresst werden.The invention relates to one-piece, stackable transport pallets high static and dynamic strength and high weather resistance Chip, fiber, powder or granulate raw or secondary raw materials, possibly in Combination, which are provided with a binding agent and preferably hot-pressed will.
Es ist bekannt, Paletten, die mit nach oben offenen Rippen versteift sind, zu fertigen (DT - OS 1 919 661).It is known to have pallets stiffened with ribs open at the top are to be manufactured (DT-OS 1 919 661).
Diese, zum Stand der Technik gehörenden Paletten haben wesentliche Nachteile. So haben beispielsweise die nach oben offenen Versteifungsrippen näherungsweise gleichen Querschnitt, wie die übrigen Teile der Palette. Dies erfolgt aus presstechnischen Gründen. Die so ausgebildeten dünnwandigen Versteifungsrippen sind empfindlich gegen Beschädigungen durch die Hubgabel der Flurförderer. Eine Beschädigung der Versteifungsrippe führt jedoch zum Verlust der Tragfähigkeit der Paletten und zu deren Bruch.These prior art pallets have essential Disadvantage. For example, the upwardly open stiffening ribs have approximately same cross-section as the other parts of the Palette. this happens for pressing reasons. The thin-walled stiffening ribs formed in this way are sensitive to damage from the lifting fork of the floor conveyor. One However, damage to the stiffening rib leads to the loss of the load-bearing capacity Pallets and their breakage.
Die Bruchgefohr der Versteifungsrippen ist zusätzlich dadurch gegeben, dass die Palette auf der Hubgabel nur mit den Rippen aufliegt (Punktlast). Die beim Fahren der Gabelstapler auf unebener Bahn auftretende Stoßbelastung wirkt hier,zusommen mit der punktförmigen Krafteinleitung und der durch die Konstruktion der Hohlrippen bedingten niedrigen Elastizität der Rippen, bruchfördernd. Des weiteren werden diese, zum Stand der Technik gehörenden Paletten mit verhältnismäßig großem Bindemittelantei gefertigt. Hierdurch wird das Produkt mit hohen Rohstoffkosten belastet, da vor allem die Beleimung einen wesentlichen Kostenfaktor darstellt.The fracture of the stiffening ribs is also given by that the pallet rests on the lifting fork only with the ribs (point load). The at Driving the forklift truck on an uneven track has an increased impact here with the point-like introduction of force and that through the construction of the hollow ribs Conditional low elasticity of the ribs, promotes breakage. Furthermore, these, prior art pallets with a relatively large amount of binder manufactured. As a result, the product is burdened with high raw material costs since before Gluing in particular is a major cost factor.
Ein weiterer Nachteil der zum Stand der Technik gehörenden Paletten besteht darin, dass der hohe Beleimungsgrad, der gleichmäßig über das Volumen der Palette verteilt ist, noch nicht ausreicht, um der Palette zufriedenstellende Witterungs- und Feuchtigkeitsbeständigkeit zu verleihen.Another disadvantage of the prior art pallets is that the high degree of gluing, which is evenly distributed over the volume of the Pallet has been distributed, is not yet sufficient to ensure that the pallet has satisfactory weather conditions. and to impart moisture resistance.
Für viele Anwendungsgebiete einer Palette ist jedoch Witterungs- und Feuchtigkeitsbeständigkeit eine wesentliche Voraussetzung.For many areas of application of a pallet, however, is weather and Moisture resistance is an essential requirement.
Der Erfindung liegt die Aufgabe zugrunde, die bisherigen Gebrauchsmängel der zum Stand der Technik gehörenden Paletten zu beseitigen, ohne deren Herstellungskosten zu vergrößern.The invention is based on the object of the previous shortcomings to eliminate prior art pallets without their manufacturing costs to enlarge.
Dies soll erfindungsgemäß dadurch geschehen, dass der Bindemittelanteil im Volumen der Palette gering ist - vorzugsweise weniger als 1,5 Gewichtsprozent - und die Ladefläche der Palette so ausgebildet ist, dass sie eine eingespannte Platte darstellt, deren Einspannung durch einen umlaufenden, höher festen Rand gebildet wird. Die Versteifungsrippen mit vorzugsweise vollem Querschnitt können hierbei ebenfalls aus höher festem Werkstoff bestehen. Eine weitere vorteilhafte Ausbildung erfindungsgemäßer Paletten besteht darin, dass die eingespannte Platte der Ladefläche selbst als Schichtkonstruktion (Sandwi chkonstruktion) ausgebildet ist. Zu diesem Zweck muss mindestens eine Plattenoberfläche ebenfalls aus höher festem Werkstoff bestehen.According to the invention, this should take place in that the binder content is low in the volume of the pallet - preferably less than 1.5 percent by weight - and the loading area of the pallet is designed so that it is clamped Plate represents the restraint of which is formed by a circumferential, higher fixed edge will. The stiffening ribs with preferably full cross-section can also consist of higher strength material. Another beneficial one Forming pallets according to the invention consists in the fact that the clamped plate the loading area itself is designed as a layered construction (sandwich construction) is. For this purpose, at least one panel surface must also be made higher consist of solid material.
Die höhere Festigkeit des Palettenwerkstoffes im umlaufenden Rand, gegebenenfalls in den Versteifungsrippen und/oder den Oberflächen der Tragplatte soll erfindungsgemäss dadurch erreicht werden, dass diese Werkstoffpartien zusätzlich beleimt werden. Die Zusotzbeleimung kann besonders günstig dadurch erfolgen, dass die Oberflächen der formgebenden Werkzeuge vor dem Füllen und Verpressen ganz oder teilweise mit zusätzlichem Bindemittel versehen werden.The higher strength of the pallet material in the circumferential edge, possibly in the stiffening ribs and / or the surfaces of the support plate is to be achieved according to the invention in that these material parts additionally be glued. The addition of glue can be carried out particularly favorably in that the surfaces of the shaping tools before filling and pressing completely or partially provided with additional binding agent.
Aus der Spanplattenfertigung ist es zwar bekannt, dass man durch schichtweises Schütten unterschiedlich beleimten Schüttgutes ähnliche Wirkung erzielen kann, dieses Vorgehen erfordert jedoch wegen der notwendigen Mindestschütthöhen der einzelnen Schichten mehr Bindemittel als die Zusatzbeleimung der Werkzeugoberflächen, und bedingt für Formteile wie sie Paletten darstellen eine aufwendige Fertigungstechnik.From the manufacture of chipboard it is known that by working in layers Pouring differently glued bulk material can achieve a similar effect, this However, the procedure requires due to the necessary minimum dumping heights of the individual Layers of more binder than the additional glue on the tool surfaces, and A complex manufacturing technique for molded parts as represented by pallets.
Über die erfindungsgemäße Festigkeitssteigerung des umlaufenden Randes, der Rippen und der Palettenoberfläche hinaus, hat die Zusatzbeleimung den wesentlichen Vorteil, dass die Paletten witterungs- und feuchtigkeitsunempfindlich werden. Da das Volumen des Palettenwerkstoffes nur mit geringen Bindemittelanteilen beleimt ist, ergibt sich durch die Zusatzbeleimung keine Kostensteigerung gegenüber den Paletten, die dem Stand der Technik entsprechen, also im ganzen Volumen höher beleimt sind.About the increase in strength of the circumferential edge according to the invention, the ribs and the surface of the pallet, the additional gluing is essential The advantage is that the pallets are insensitive to weather and moisture. There the volume of the pallet material is only glued with a small amount of binder is, the additional gluing does not result in any increase in costs compared to the Pallets that correspond to the state of the art, i.e. with higher glue in the entire volume are.
Die inhomogene Bindemittelverteilung bewirkt also erfindungsgemäß eine wesentliche Verbesserung der Gebrauchseigenschaften der Palette nicht nur dadurch, dass ihre Festigkeitseigenschaften gesteigert werden, sondern auch dadurch, dass ihre Beständigkeit gegen Witterungs- und Feuchtigkeitseinflüsse erheblich verbessert wird. Hierbei erhöhen sich die Fertigungskosten gegenüber den Paletten, die nach dem Stand der Technik gefertigt sind nicht, da durch die inhomogene Verteilung des kostenintensiven Bindemittels die Gesamtmenge der Beleimung nicht gesteigert wird, sondern die gewünschten Materialeigenschaften örtlich so verteilt werden, dass sie dem Optimum sowohl hinsichtlich der Festigke itseigenschaften, als auch hinsichtlich Witterungs- und Feuchtigkeitsbeständigkeit entsprechen.The inhomogeneous distribution of the binder is thus achieved according to the invention a significant improvement in the usage properties of the pallet not only because that their strength properties are increased, but also by the fact that their resistance to the effects of weather and moisture is significantly improved will. This increases the production costs compared to the pallets that are after are not manufactured according to the state of the art, as the inhomogeneous distribution of the cost-intensive binding agent, the total amount of glue is not increased, but the desired material properties are locally distributed in such a way that they the optimum both in terms of strength and properties Weather and moisture resistance correspond.
Die erfindungsgemäße, örtliche Zusatzbeleimung kann mit dem gleichen Bindemittel geschehen, mit dem auch der Werkstoff des Palettenkernes beleimt ist. Besonders vorteilhaft wird sich jedoch eine Zusatzbeleimung auswirken, die aus Werkstoffen besteht, die der vorgesehenen Optimierung angepasst sind. Dies können vorzugsweise Bindemittel sein, die filmbildende Eigenschaften aufweisen, und sich mit der Beleimung des Grundstoffes beim Verpressen gut verbinden.The local additional gluing according to the invention can be used with the same Binder happen, with which the material of the pallet core is also glued. However, additional gluing made from materials will be particularly advantageous exists that are adapted to the intended optimization. This can preferably Be binders that have film-forming properties and deal with the gluing of the basic material combine well during pressing.
