Abstract

In a process for producing pallets from plastic, glass fibre and/or mineral fibre wastes treated with a synthetic resin are compression-moulded in a moulding press to form pallets.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Paletten aus Kunststoff.The invention relates to a method for producing Plastic pallets.

In der Regel werden Paletten heute aus Holz hergestellt. Diese Paletten haben sehr gute Gebrauchseigenschaften, sind jedoch für den schnellen Verbrauch gedacht. Zudem bedarf die Herstellung einer Holzpalette eines erheblichen Aufwandes an Zeit und Kosten.As a rule, pallets are now made from wood. These pallets have very good usage properties however intended for quick consumption. In addition, the Manufacturing a wooden pallet at a considerable cost Time and cost.

Paletten mit einer größeren Lebensdauer werden in der Regel aus Kunststoff hergestellt. Ein hierfür geeigneter Kunststoff wird entweder in eine entsprechende Spritzform eingebracht oder im Preß- oder Spritzpreßverfahren hergestellt. Derartige Paletten sind aufgrund ihres Materials und ihrer Herstel­ lungsweise sehr teuer.Pallets with a longer lifespan are usually made of plastic. A suitable plastic for this is either placed in an appropriate injection mold or manufactured in the pressing or transfer molding process. Such Pallets are due to their material and their manufacture very expensive.

Der Erfinder hat sich zum Ziel gesetzt unter Verwendung eines billigen Kunststoffmaterials ein Verfahren zu entwickeln, mit welchem Paletten mit hervorragenden Gebrauchseigenschaften günstig und billig hergestellt werden können.The inventor set himself the goal using a cheap plastic material to develop a process with which pallets with excellent usage properties can be manufactured cheaply and cheaply.

Zur Lösung dieser Aufgabe führt, daß mit einem Kunstharz versetzte Glas- und/oder Mineralfaserabfälle in einer Form­ presse zu Paletten verpreßt werden.To solve this problem that leads with a synthetic resin staggered glass and / or mineral fiber waste in a mold press to be pressed into pallets.

Erfindungsgemäß sollen als Abfälle insbesondere solche verwendet werden, die bei der Schleifscheibenherstellung an­ fallen. Diese Abfälle sind für Paletten sehr geeignet, da sie einmal billig zu erwerben sind und zum anderen sehr gute Ge­ brauchseigenschaften aufweisen. Sie sind im Gebrauch unem­ pfindlich und haben eine hohe Lebensdauer.According to the invention, waste in particular should be such used in grinding wheel manufacture fall. This waste is very suitable for pallets as it are cheap to buy and very good Ge have useful properties. They are unemployed sensitive and have a long service life.

Bevorzugt erfolgt das Pressen unter Wärmezugabe, da hierdurch die Fließfähigkeit des Materials und damit seine Verformbar­ keit verbessert wird. Unregelmäßigkeiten des Ausgangsmate­ rials werden so ausgeglichen.The pressing is preferably carried out with the addition of heat, as a result of this the flowability of the material and thus its deformability speed is improved. Irregularities in the starting material rials are balanced.

Da die Abfälle in der Regel sehr ungleichmäßig anfallen, hat es sich als günstiger erwiesen, diese vor dem Pressen durch Zerkleinern zu homogenisieren. Dies kann mit einem Zerhacker oder einer ähnlichen Vorrichtung erfolgen.Since the waste is usually generated very unevenly it turned out to be cheaper to go through this before pressing Shred to homogenize. This can be done with a chopper or a similar device.

Weiterhin sollten die Abfälle vor dem Pressen verdichtet werden, damit die innere Struktur der fertigen Palette ver­ bessert wird durch Verringerung der Hohlräume. Allerdings haben eine begrenzte Anzahl von Hohlräumen wiederum den Vor­ teil, daß die Palette leichter wird als beispielsweise Paletten aus Vollkunststoff. Da die Glas- bzw. Mineralfaser­ einlagen wie Armierungen wirken, wird die Stabilität der Palette auch durch eine begrenzte Anzahl von Hohlräumen nicht beeinträchtigt. Furthermore, the waste should be compacted before pressing so that the inner structure of the finished pallet ver is improved by reducing the voids. Indeed have a limited number of cavities in turn partly that the pallet is lighter than, for example All-plastic pallets. Because the glass or mineral fiber inserts act like reinforcements, the stability of the Pallet also not due to a limited number of cavities impaired.  

Das Verdichten geschieht beispielsweise in einer Vibrations­ rinne, an deren Ende bevorzugt eine Einrichtung zur Wärmebe­ aufschlagung des verdichteten Materials angeordnet ist. Eine kurzfristige Wärmebeaufschlagung ist so ausgelegt, daß nur die Oberfläche eines bestimmten Bereichs aufgeschmolzen wird und zusammenfließt. Hierdurch entsteht eine Platte, welche als Stück weitertransportiert und bearbeitet werden kann. Im Inneren dieser Platte findet noch kein Aufschmelzen statt. Dies wird erst in der Presse erfolgen.The compression takes place, for example, in a vibration gutter, at the end preferably a device for heating impact of the compacted material is arranged. A short-term heat exposure is designed so that only the surface of a certain area is melted and flows together. This creates a plate, which can be transported and processed as a piece. in the There is still no melting inside this plate. This will only be done in the press.

Diese so hergestellten Formlinge werden dann, soweit notwendig auf die etwaige Form der späteren Palette geschnitten, damit sie leichter in die Presse gegeben und dort bearbeitet werden können. Die dabei entstehenden Abfälle können wieder zurück in den Container gegeben und einem erneuten Arbeitsvorgang zugeführt werden.These moldings thus produced are then, as far necessary for the possible shape of the later pallet cut to make it easier to put in the press and can be edited there. The resulting waste can be put back in the container and one be carried out again.

Durch dieses erfindungsgemäße Verfahren werden Paletten hergestellt, welche eine sehr hohe Lebensdauer besitzen und insbesondere zur Verwendung in der Getränkeindustrie zum Transport von Flaschenkästen od.dgl. geeignet erscheinen. In­ folge des gewählten Abfalls ist die Oberfläche der Palette im Gegensatz zu bekannten Paletten relativ rauh, so daß zu transportierende Güter nicht verrutschen.With this method according to the invention, pallets manufactured, which have a very long life and especially for use in the beverage industry Transport of bottle crates or the like seem suitable. In the surface of the pallet in the In contrast to known pallets relatively rough, so that too do not slip transporting goods.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung; diese zeigt in ihrer einzigen Figur eine blockschematische Darstellung des erfindungsgemäßen Verfahrensablaufes.Further advantages, features and details of the invention result from the following description of a preferred embodiment and with reference to the drawing; in its single figure, this shows a block diagram Representation of the process flow according to the invention.

Die mit Kunstharz getränkten Glas-oder Mineralfaserabfälle werden in einem Container 1 od.dgl angeliefert und gegebenen­ falls zwischengelagert.The glass or mineral fiber waste impregnated with synthetic resin is delivered in a container 1 or the like and, if necessary, stored temporarily.

Bei Bedarf werden diese Abfälle aus dem Container 1 in einen Zerhacker oder ähnliche Zerkleinerungseinrichtung 2 eingege­ ben, wo sie zu relativ kleinen Stücken verarbeitet werden.If necessary, these wastes from the container 1 are placed in a chopper or similar shredding device 2 , where they are processed into relatively small pieces.

Die so vorbereiteten Abfälle gelangen dann aus dem Zerhacker 2 in Vibrationsförderrinnen 3, wobei auch hier gegebenenfalls ein Zwischenlager dazwischen geschaltet sein kann. In den Vibrationsförderrinnen wird das Material verdichtet und am Ende mit Wärme durch eine geeignete wärmeemittierende Vor­ richtung 4 beaufschlagt. Die Wärmezugabe erfolgt so, daß lediglich die Oberflächen des verdichteten Materials aufge­ weicht werden. Dadurch wird ein Auseinanderfallen nach den Förderrinnen 3 bzw. der Wärmvorrichtung 4 verhindert.The waste prepared in this way then passes from the chopper 2 into vibrating conveyor troughs 3 , an intermediate storage facility also being able to be interposed here if necessary. In the vibrating feed troughs, the material is compacted and, at the end, heat is applied by a suitable heat-emitting device 4 . The heat is added so that only the surfaces of the compressed material are softened up. This prevents falling apart after the conveyor troughs 3 or the heating device 4 .

Die so erzeugten Platten gelangen dann in Schneideinrichtun­ gen 5, wo ihnen die äußeren Maße einer Palette gegeben werden.The plates thus generated then go to Schneideinrichtun gene 5 , where they are given the outer dimensions of a pallet.

In einer nächsten Zwischenstufe erfolgt die Zwischenlagerung 6 dieser geschnittenen Platten.In a next intermediate stage, the intermediate storage 6 of these cut plates takes place.

Wiederum bei Bedarf werden die Platten vom Zwischenlager 6 geholt und mit einer Presse 7 bearbeitet, in welcher den Platten die Endform einer Palette durch entsprechendes Form­ werkzeug gegeben wird. Wenn notwendig erfolgt dies unter Wärmebeaufschlagung.Again if necessary, the plates are fetched from the intermediate storage 6 and processed with a press 7 , in which the plates are given the final shape of a pallet by means of a corresponding molding tool. If necessary, this is done under heat.
