Description
Die Erfindung betrifft eine Transportpalette aus span-, faser-, pulver- oder granulatförmigen Roh- bzw. Sekundärrohstoffen, die mit einem Bindemittel versehen sind und einstückig warm gepreßt werden, wobei die Deckplatte durch einen umlaufenden Rand und ein Netzwerk von Versteifungsrippen versteift ist, sowie ein Verfahren zu ihrer Herstellung.The invention relates to a transport pallet made of chip, fiber, powder or granulate raw or Secondary raw materials, which are provided with a binder and are hot-pressed in one piece, wherein the cover plate is stiffened by a circumferential edge and a network of stiffening ribs, as well as a Process for their manufacture.
Eine derartige Transportpalette ist aus der DE-OS 19 19 661 bekannt.Such a transport pallet is known from DE-OS 19 19 661.
Diese Transportpalette hat wesentliche Nachteile. So haben ihre nach oben offenen Versteifungsrippen näherungsweise gleichen Querschnitt wie die übrigen Teile der Palette. Dies erfolgt aus preßtechnischen Gründen.This transport pallet has significant disadvantages. So have their stiffening ribs that are open at the top approximately the same cross-section as the other parts of the pallet. This is done from press technology Establish.
Die so ausgebildeten dünnwandigen Versteifungsrippen sind empfindlich gegen Beschädigungen durch die Hubgabeln der Flurförderer. Eine Beschädigung der Versteifungsrippe führt jedoch zum Verlust der Tragfähigkeit der Palette und zu deren Bruch.The thin-walled stiffening ribs formed in this way are sensitive to damage by the Lifting forks of the floor conveyor. However, damage to the stiffening rib leads to the loss of the Load-bearing capacity of the pallet and its breakage.
Die Bruchgefahr 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 zusammen mit der punktförmigen Krafteinleitung und der durch die Konstruktion der Hohlrippen bedingten niedrigen Elastizität der Rippen bruchfördernd. Des weiteren werden diese Paletten mit verhältnismäßig großem Bindemittelanteil gefertigt. Hierdurch wird das Produkt mit hohen Rohstoffkosten belastet, da vor allem die Beleimung teuer ist. Ein weiterer Nachteil dieser Paletten besteht darin, daß der hohe Beleimungsgrad, der gleichmäßig über das Volumen der Palette verteilt ist, noch nicht ausreicht, um der Palette zufriedenstellende Witte-The risk of breakage of the stiffening ribs is also given by the fact that the pallet on the lifting fork only rests with the ribs (point load). The one that occurs when driving the forklift on an uneven track Impact loading works here together with the punctiform introduction of force and that through the construction the hollow ribs due to the low elasticity of the ribs promotes breakage. Furthermore, these Pallets made with a relatively large proportion of binding agent. This makes the product with high Raw material costs are burdened, since the gluing in particular is expensive. Another disadvantage of these pallets is in that the high degree of gluing, which is evenly distributed over the volume of the pallet, is not yet sufficient to provide satisfactory weather conditions for the pallet.

rungs- und Feuchtigkeitsbeständigkeit zu verleihen, die für viele Anwendungsgebiete erforderlich istto impart resistance and moisture resistance to the is required for many areas of application
Der Erfindung liegt die Aufgabe zugrunde, eine Transportpalette der eingangs genannten Art so zu verbessern, daß deren Festigkeit und Witterungsbeständigkeit sich erhöht, ohne daß der Gesamtaufwand an Werkstoff- und Herstellungskosten vergrößert wird.The invention is based on the object of providing a transport pallet of the type mentioned at the outset improve so that their strength and weather resistance are increased without reducing the overall cost Material and manufacturing costs are increased.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, daß die Deckplatte eine eingespannte Platte darstellt, deren Einspannung durch den umlaufenden Rand gebildet wird, und daß die Oberflächenschicht der Deckplatte am umlaufenden Rand und/oder bei den Versteifungsrippen einen höheren Bindemittelanteil als im übrigen Volumen der Palette aufweist, dessen Bindemittelanteil vorzugsweise weniger als 1,5 Gewichtsprozent beträgt.To solve this problem it is proposed according to the invention that the cover plate a represents clamped plate, the restraint is formed by the circumferential edge, and that the Surface layer of the cover plate on the circumferential edge and / or at the stiffening ribs has a higher proportion of binder than in the rest of the volume of the pallet, the proportion of which is preferred is less than 1.5 percent by weight.
Durch die inhomogene Bindemittelverteilung wird zweierlei erreicht: Einmal werden Werkstoffbereiche höherer Festigkeit gerade an den hochbelasteten Stellen der Palette geschaffen, der Werkstoff wird insgesamt festigkeitsmäßig besser ausgenutzt. Zum anderen hat über die Festigkeitssteigerung des umlaufenden Randes, der Rippen und der Palettenoberfläche hinaus der örtliche Bindemittelanteil des an sich niedrig beleimten Werkstoffes den wesentlichen Vorteil, daß die Paletten witterungs- und feuchtigkeitsunempfindlicher werden, da der örtliche Bindemittelanteil der Oberfläche der Deckplatte wie eine Versiegelung wirkt und den Feuchtigkeitsangriff auf das an sich niedrig beleimte Volumen der Palette vermindert.The inhomogeneous distribution of the binder achieves two things: On the one hand, there are material areas higher strength is created especially at the highly stressed areas of the pallet, the material is Overall better used in terms of strength. On the other hand it has to increase the strength of the circumferential Edge, the ribs and the pallet surface in addition, the local binding agent content of the itself is low glued material has the essential advantage that the pallets are less sensitive to weathering and moisture as the local binding agent on the surface of the cover plate acts like a seal and reduces the moisture attack on the volume of the pallet, which is inherently low in glue.
Die ungleichmäßige Bindemittelverteilung bewirkt eine wesentliche Verbesserung der Gebrauchseigenschaften der Palette nicht nur dadurch, daß ihre Festigkeitseigenschaften gesteigert werden, sondern auch dadurch, daß ihre Beständigkeit gegen Witterungsund Feuchtigkeitseinflüsse erheblich verbessert wird. Hierbei erhöhen sich die Fertigungskosten nicht, da durch die ungleichmäßige Verteilung des kostenintensiven Bindemittels die Gesamtmenge des Bindemittels nicht gesteigert wird, sondern die gewünschten Materialeigenschaften örtlich so verteilt werden, daß sie dem Optimum sowohl hinsichtlich der Festigkeitseigenschaften als auch hinsichtlich Witterungs- und Feuchtigkeitsbeständigkeit entsprechen.The uneven distribution of the binder causes a significant improvement in the properties of use the pallet not only in that its strength properties are increased, but also by the fact that their resistance to the effects of weathering and moisture is considerably improved. This does not increase the manufacturing costs because of the uneven distribution of the cost-intensive Binder the total amount of binder is not increased, but the desired Material properties are locally distributed so that they are the optimum both in terms of strength properties as well as with regard to weather and moisture resistance.
Aus der Spanplattenferligung ist es bekannt, daß man durch schichtweises Schütten unterschiedlich belehnten Schüttgutes ungleichmäßige Bindcmittelverteilung erzielen kann, dieses Vorgehen erfordert jedoch wegen der notwendigen Mindestschütthöhen der einzelnen Schichten viel Bindemittel und eine verhältnismäßig aufwendige Fertigungstechnik. Die ungleichmäßige Bindemittelverteilung soll daher in einem Herstellungsverfahren dadurch erreicht werden, daß das Preßwerkzeug mit Füllgut niedrigen Beleimungsgrades gefüllt wird und daß das Bindemittel für die Oberfläche der Deckplatte und deren umlaufenden Rand und/oder für die Versteifungsrippen auf die Oberflächen des formgebenden Werkzeuges oder Teile davon aufgebracht wird, wobei hierfür ein gleiches oder ein anderes Bindemittel wie für das Füllgut verwendet wird.From the manufacture of chipboard it is known that one leaned differently by pouring it in layers Bulk material can achieve uneven binder distribution, but this procedure requires due the necessary minimum bed heights of the individual layers a lot of binder and a proportionate one complex manufacturing technology. The uneven distribution of the binder should therefore be used in a manufacturing process can be achieved in that the pressing tool is filled with filling material with a low degree of gluing and that the binder for the surface of the cover plate and its peripheral edge and / or for the stiffening ribs are applied to the surfaces of the forming tool or parts thereof, for this purpose, an identical or a different binding agent is used as for the filling material.
Dieses Verfahren gestattet es, Bindemittel örtlich mit geringstmöglichem Bindemittelaufwand und ohne nennenswerte Erhöhung des Fertigungsaufwandes gezielt aufzubringen.This method allows binding agents to be produced locally with the least possible amount of binding agent and without any significant amount of binding agent To raise the production effort in a targeted manner.
Besonders vorteilhaft wird sich jedoch ein Bindemittel auswirken, das aus Werkstoffen besteht, die der vorgesehenen Optimierung angepaßt sind. Dies können vorzugsweise Bindemittel sein, die filmbildende Einen-However, a binder is particularly advantageous affect, which consists of materials that are adapted to the intended optimization. This can preferably be binders, the film-forming one-

The process of applying the binder locally to the tool surfaces to apply, it allows in a very simple way to optimize different binders of the product properties.
