Description
Die vorliegende Patentanmeldung betrifft ein Verfahren zur Herstellung einer Transportverpackung für Caiciumcarbid zum Einsatz in dosierten Kleinmengen.The present patent application relates to a method for producing a transport packaging for calcium carbide for use in metered small quantities.
Bisher ist es üblich, Calciumcarbid in kleinen Mengen portioniert in Metalltrommeln abzupakken, wobei je Trommel etwa 100 kg Calciumcarbid enthalten sind. Nachteilig ist hierbei, daß die Trommeln wegen ihrer runden Grundfläche beim Transport die Ladefläche auf dem Fahrzeug nur unvollständig auszunutzen gestatten. Darüber hinaus müssen die leeren Trommeln wegen ihres relativ hohen Anschaffungspreises vom Verbrauchsort zum Befüllort zurücktransportiert werden, was insbesondere bei im Ausland gelegenen Verbrauchsorten beträchtliche zusätzliche Frachtkosten verursacht. Aus der DE-C-2 033 160 ist zwar eine Vorrichtung zum Dosieren von feuchtigkeitsempfindlichen Feststoffen wie Calciumcarbid bekannt, bei welcher mehrere, in ihrem Oberteil quadratische und an ihrem unteren Ende konisch auslaufende Behälter verwendet werden, wobei diese Behälter gleichzeitig zum Transport und zur Lagerung des Calciumcarbides dienen und wobei jeder Behälter etwa 1000 kg Calciumcarbid faßt. Diese Vorrichtung gestattet jedoch keine hinreichend genaue Dosierung von Kleinmengen, beispielsweise von 5 kg, da das auf ihren Druckmeßdosen ruhende Taragewicht im Verhältnis dazu zu groß ist.Up to now, it has been customary to pack small amounts of calcium carbide in metal drums, each drum containing about 100 kg of calcium carbide. The disadvantage here is that the drums only allow incomplete use of the loading area on the vehicle because of their round base. In addition, because of their relatively high purchase price, the empty drums have to be transported back from the place of consumption to the place of filling, which causes considerable additional freight costs, particularly for places of consumption located abroad. DE-C-2 033 160 discloses a device for metering moisture-sensitive solids such as calcium carbide, in which several containers are used which are square in their upper part and tapered at their lower end, these containers being used simultaneously for transport and storage serve the calcium carbide and each container holds about 1000 kg of calcium carbide. However, this device does not allow a sufficiently precise metering of small quantities, for example of 5 kg, since the tare weight resting on its pressure cells is too large in relation to it.
Aus der US-A-3 670 880 ist eine Verpackung für in Beuteln befindliche körnige Produkte bekannt, welche aus einem auf einer Palette befestigten, mehrschichtigen Wellpappe-Behälter besteht. In den Behälter werden die Beutel eingelegt und über die Höhe seiner Seitenwände hinaus aufgestapelt. Über die aufgestapelten Beutel wird ein aus mehrschichtiger Wellpappe bestehender Verschluß übergeschoben, welcher ein flaches Oberteil sowie nach unten weisende Seitenwände umfaßt und welcher die Seitenwände des Behälters teilweise umgreift. Um die Oberseite und die Seitenwände des Verschlusses sowie um die Seitenwände des Behälters wird eine schrumpfbare Kunststoff-Folie gelegt und in einem Schrumpfofen bei einer Temperaturvon etwa 150° C aufgeschrumpft.From US-A-3 670 880 a packaging for granular products in bags is known, which consists of a multi-layer corrugated cardboard container attached to a pallet. The bags are placed in the container and stacked beyond the height of its side walls. Over the stacked bags, a closure consisting of multilayer corrugated cardboard is pushed over, which comprises a flat upper part and downward-facing side walls and which partially engages around the side walls of the container. A shrinkable plastic film is placed around the top and side walls of the closure and around the side walls of the container and shrunk in a shrink oven at a temperature of about 150 ° C.
Der Behälter nach der US-A-1 875 497 wird aus vier Seitenwänden sowie je vier oberen und unteren Verschlußklappen, welche alle miteinander verbunden sind, aufgebaut. Nach Schließen der unteren Verschlußklappen kann in den Behälter ein an seinen Seitenwänden anliegender Sack eingelegt werden, welcher bis zur Höhe der Seitenwände mit Schüttgut befüllt werden kann. Es kann aber auch nach Schließen der unteren Verschlußklappen in den Behälter ein zylinderförmiger, die Seitenwände tangierender Einsatz eingebracht werden, während im Bereich der Ekken des Behälters je eine Verstärkungsröhre eingesetzt ist, welche sowohl den zylinderförmigen Einsatz als auch die Seitenwände berührt.The container according to US-A-1 875 497 is constructed from four side walls and four upper and lower closure flaps, which are all connected to one another. After the lower flaps have been closed, a sack lying against its side walls can be inserted into the container, which can be filled with bulk material up to the height of the side walls. However, after the lower flaps have been closed, a cylindrical insert affecting the side walls can also be introduced, while in the area of the corners of the container a reinforcement tube is inserted which touches both the cylindrical insert and the side walls.
Der Behälter zur Handhabung von losem Material nach der US-A-3 073 500 besteht aus einem inneren und einem äußeren Kasten, welche unter Zwischenlage von Eckenverstärkungswinkeln ineinander geschoben worden sind. Die mit Abstand voneinander angeordneten Kästen sind auf einer Palette befestigt. Nach Füllung des inneren Kastens mit dem losen Material werden zunächst die oberen Bereiche der vier Seiten des inneren Kastens nach innen geklappt und dann die als Deckel ausgebildeten oberen Bereiche des äußeren Kastens zugeklappt.The container for handling loose material according to US-A-3 073 500 consists of an inner and an outer box which have been pushed into one another with the interposition of corner reinforcement angles. The boxes, which are spaced apart, are attached to a pallet. After filling the inner box with the loose material, the upper areas of the four sides of the inner box are first folded inwards and then the upper areas of the outer box designed as lids are closed.
Aus der US-A-2 965 276 ist eine Palette bekannt, welche aus unteren und oberen Rippen besteht, die unter Zwischenlage von Klötzen mit vertikalem Abstand voneinander angeordnet sind. Mehrere mit Abstand voneinander aufgestellte derartig beschaffene Rippen sind durch Querstäbe miteinander verbunden. Auf dieser Palette ist ein quaderförmiger Behälter befestigt, welcher mit einem Deckel verschließbar ist. Behälter und Deckel sind in Querrichtung mehrfach von Stahlbändern umgriffen.From US-A-2 965 276 a pallet is known which consists of lower and upper ribs which are arranged with blocks spaced vertically apart. A plurality of ribs constructed in this way and spaced apart from one another are connected to one another by cross bars. A rectangular container is fastened to this pallet and can be closed with a lid. Containers and lids are encompassed several times by steel strips in the transverse direction.
Bei dem aus der GB-A-1 512371 bekannten Verfahren zur Verpackung von Autokühlern werden die Kühler zwischen je einem flachen Boden und Deckel aus Karton oder Kunststoff auf einer Palette gestapelt und mit Metallbändern umreift. Die so gestapelten Kühler werden vollständig in einen Schrumpffilm eingehüllt. Der Schrumpffilm wird durch Behandeln mit heißer Luft geschrumpft, wodurch der Kühlerstapel in seiner Lage gehalten wird und die Kühler eingesiegelt werden.In the method for packaging car coolers known from GB-A-1 512371, the coolers are stacked on a pallet between a flat bottom and a lid made of cardboard or plastic and strapped with metal straps. The coolers stacked in this way are completely encased in a shrink film. The shrink film is shrunk by treatment with hot air, which holds the cooler stack in place and seals the coolers.
Nach der FR-A-2 139 002 wird ein durch ein kombiniertes Extrusion-Blas-Verfahren hergestellter Polyäthylen-Schlauch mit einer Wandstärke von etwa 0,1 mm aufgeschnitten, in spezieller Form gefaltet, in Querrichtung verschweißt und unter Ausbildung von Säcken zerschnitten. Ein derartiger Sack wird über eine im wesentlichen rechteckige Palettenladung gebracht. Nachdem die Palettenladung auf diese Weise mit dem Sack überzogen ist, wird sie in einem Ofen kurzzeitig Temperaturen von etwa 200° C ausgesetzt, wobei der Sack aufschrumpft.According to FR-A-2 139 002, a polyethylene tube produced by a combined extrusion blow molding process is cut open with a wall thickness of approximately 0.1 mm, folded in a special form, welded in the transverse direction and cut to form sacks. Such a sack is brought over an essentially rectangular pallet load. After the pallet load is covered with the sack in this way, it is briefly exposed to temperatures of around 200 ° C in an oven, whereby the sack shrinks.
Es ist Aufgabe der vorliegenden Erfindung, ein Verfahren zur Herstellung einer Transportverpackung für Calciumcarbid in Kleinmengen anzugeben, bei welchem unter optimaler Ausnutzung der Ladefläche des Transportfahrzeuges auf teure metallische Emballagen verzichtet werden kann und die Carbidmengen genau dosiert sind. Das wird erfindungsgemäß dadurch erreicht, daß man eine Vielzahl von mit einer vorgegebenen Menge Calciumcarbid gefüllte, verschlossene Beutel aus Kunststoff-Folie, vorzugsweise Polyethylen-Folie, mit einer Dicke von 0,05 bis 0,4 mm und einer flächenbezogenen Masse von 50 bis 400 g/m2 in mehreren Lagen übereinander in eine auf einer Palette befestigte, aus Mehrfachpappe hergestellte Schachtel einpackt und anschließend die Schachtel verschließt; daß in die Schachtel eine Ringeinlage eingestellt ist, welche an den vertikalen Innenwänden der Schachtel mit Ausnahme der Bereiche ihrer Ekken anliegt; daß in jeder Ecke der Schachtel ein sich von ihrem Boden bis zu ihrem Deckel erstreckender Rohrabschnitt steht, wobei die Rohrabschnitte von der Ringeinlage unter Stabilisierung ihrer Lage tangiert werden; daß die Schachtel äußere Boden- und Deckelverschlußklappen aufweist, welche sich gegenseitig vollständig überlappen; daß man auf die Oberseite der verschlossenen Schachtel einen Abdeckrost auflegt; daß man die verschlossene Schachtel, den Abdeckrost und die Palette in Längsrichtung und/oder Querrichtung mindestens je einmal mit einem Band umreift; daß man nach der Umreifung die Schachtel, den Abdeckrost und die Palette mit einer eine flächenbezogene Masse von 55 bis 460 g/M 2 aufweisenden Schrumpffolie überzieht sowie die Schrumpffolie durch Anblasen mit Warmluft einschrumpft; und daß bis zu drei mit Schrumpffolie überzogene Paletten, Schachteln und Abdeckroste übereinander stapelbar sind.It is an object of the present invention to provide a method for producing transport packaging for calcium carbide in small quantities, in which expensive metallic packaging can be dispensed with and optimal use of the loading area of the transport vehicle and the amounts of carbide are precisely metered. This is achieved according to the invention in that a large number of sealed bags made of plastic film, preferably polyethylene film, filled with a predetermined amount of calcium carbide, with a thickness of 0.05 to 0.4 mm and a mass per unit area of 50 to 400 g / m 2 packed in several layers one above the other in a box fastened on a pallet, made of multiple cardboard and then closing the box; that a ring insert is inserted in the box, which lies against the vertical inner walls of the box with the exception of the areas of its corners; that in each corner of the box there is a pipe section extending from its bottom to its lid, the pipe sections being affected by the ring insert while stabilizing their position; that the box has outer bottom and lid closure flaps which completely overlap each other; that a covering grate is placed on the top of the sealed box; that one straps the closed box, the cover grate and the pallet in the longitudinal and / or transverse direction at least once each with a band; that after the strapping, the box, the covering grate and the pallet are covered with a surface-based mass of 55 to 460 g / M 2 shrink film and the shrink film is shrunk by blowing with warm air; and that up to three pallets, boxes and cover grids covered with shrink film can be stacked on top of one another.
Das Verfahren gemäß der Erfindung kann auch noch dadurch ausgestaltet sein, daß man die verschlossene Schachtel, den Abdeckrost und die Palette in Längsrichtung und/oder in Querrichtung je zweimal mit einem Band umreift.The method according to the invention can also be designed by strapping the closed box, the cover grate and the pallet twice in the longitudinal direction and / or in the transverse direction with a band.
Beim erfindungsgemäßen Verfahren wird eine Einmal-Palette, welche vorzugsweise als Zweiwege-Palette ausgebildet ist (vergl. DIN 15 145, August 1977), aus Holz verwendet, welche zusammen mit der Schachtel und dem Abdeckrost nach Entnahme des Calciumcarbides am Verbrauchsort, beispielsweise durch Verbrennen, leicht zu beseitigen ist.In the method according to the invention, a single-use pallet, which is preferably designed as a two-way pallet (see DIN 15 145, August 1977), made of wood, which together with the box and the cover grate after removal of the calcium carbide at the point of use, for example by burning , is easy to remove.
Das Einfüllen des Calciumcarbides in aus Kunststoff-Folie bestehende Beutel und ihr gasdichtes Verschließen durch Zuschweißen erfolgt beim Verfahren gemäß der Erfindung vorteilhafterweise mit einer entsprechend konstruierten Maschine unter Verwendung eines KunststoffSchlauches. Durch die maschinelle Handhabung wird einerseits verhindert, daß Feuchtigkeit in die Beutel gelangt und andererseits eine genaue Dosierung garantiert.The filling of the calcium carbide into bags made of plastic film and their gas-tight sealing by welding is advantageously carried out in the method according to the invention with a correspondingly constructed machine using a plastic tube. The mechanical handling on the one hand prevents moisture from getting into the bags and on the other hand guarantees precise dosing.
Durch das Auflegen eines Abdeckrostes auf die Oberseite der verschlossenen Schachtel beim erfindungsgemäßen Verfahren wird einerseits verhindert, daß die Band-Umreifung die oberen Kanten der Schachtel durchschneidet und andererseits die Stapelfähigkeit der mit Schrumpffolie überzogenen Schachtel ermöglicht.By placing a cover grate on the top of the closed box in the method according to the invention, on the one hand it is prevented that the strapping cuts through the upper edges of the box and on the other hand enables the stackability of the box covered with shrink film.
Beim Verfahren gemäß der Erfindung wird die Stapelfähigkeit der Schachteln dadurch erhöht, daß in ihren vier Ecken vom Boden bis zur Decke reichende Rohrabschnitte angeordnet sind.In the method according to the invention, the stackability of the boxes is increased in that pipe sections extending from the floor to the ceiling are arranged in their four corners.
Durch die innerhalb der Schachtel befindliche Ringeinlage wird beim erfindungsgemäßen Verfahren einerseits die Festigkeit der Wände der Schachtel erhöht und andererseits eine Lagestabilisierung der Rohrabschnitte erreicht.Due to the ring insert located inside the box, the strength of the walls of the box is increased in the method according to the invention on the one hand and the position of the pipe sections is stabilized on the other hand.
Schließlich bewirkt das gegenseitige vollständige Überlappen von Boden- und Deckelverschlußklappen beim Verfahren gemäß der Erfindung eine Erhöhung der Festigkeit von Boden und Deckel der Schachtel.Finally, the complete overlap of the bottom and lid closure flaps in the method according to the invention increases the strength of the bottom and lid of the box.
Calciumcarbid in Kleinmengen, beispielswei= se 5 kg, wird zum Entschwefeln von kleineren Mengen Eisenschmelze in Gießereien verwendet, wobei das Calciumcarbid im Beutel in die Eisenschmelze geworfen wird. Calciumcarbid in diesen Mengen findet weiterhin zum Füllen von Acetylen-Kleinentwicklern Anwendung.Calcium carbide in small quantities, for example = 5 kg, is used for the desulfurization of small amounts of molten iron in foundries, the calcium carbide in the bag being thrown into the molten iron. Calcium carbide in these quantities continues to be used to fill small acetylene developers.
