Description

Verfahren zum Herstellen eines mehrschichtigen Förderbandes Es sind zahlreiche Förderbänder bekannt, welche aus mehreren Gewebebahnen bestehen, die mit natürlichem oder synthetischem Kautschuk oder mit Polyvinylchloridschichten verbunden sind. Die Herstellung derartiger Förderbänder erfolgt meist so, daß die mit Kautschuk oder Polyvinylchlorid oder anderen Kunststoffen imprägnierten Gewebebahnen aufeinandergelegt und mit einer entsprechenden Deckplatte aus dem gleichen Material versehen und anschließend kontinuierlich oder schrittweise unter Druck und Wärme zu einem einheitlichen fertigen Gebilde, dem endgültigen Förderband, verpreßt werden. Die Herstellung von Förderbändern aus Gewebebahnen mit Zwischenschichten aus Polyvinylchlorid und einer Polyvinylchloriddeckplatte stößt auf keine nennenswerten Schwierigkeiten. Ähnliches gilt für Förderbänder, bei denen an Stelle des Polyvinylchlorids ein natürlicher oder künstlicher Kautschuk sowohl für die Innenschichten zwischen den Gewebebahnen als auch für die Außenschicht oder Deckplatte verwendet wird.Method of making a multilayer conveyor belt There are numerous conveyor belts known, which consist of several webs of fabric that with natural or synthetic rubber or with polyvinyl chloride layers are connected. The production of such conveyor belts is usually done so that the Fabric sheets impregnated with rubber or polyvinyl chloride or other plastics placed on top of one another and with a corresponding cover plate made of the same material and then continuously or gradually under pressure and heat be pressed into a uniform finished structure, the final conveyor belt. The manufacture of conveyor belts from webs of fabric with intermediate layers of polyvinyl chloride and a polyvinyl chloride faceplate encountered no significant difficulties. The same applies to conveyor belts, where the polyvinyl chloride is replaced by a natural one or synthetic rubber for both the inner layers between the fabric panels as well as for the outer layer or cover plate.

Für bestimmte Sonderzwecke und insbesondere für Förderbänder im Bergwerksbetrieb ist es erwünscht, nur den aus Gewebebahnen bestehenden Kern mit Polyvinylchloridschichten zu verbinden, da die mit Polyvinylchlorid imprägnierten Gewebebahnen bessere Eigenschaften bezüglich Flammwidrigkeit, Festigkeit, Durchschlagsfestigkeit und Arbeitsaufnahmefähigkeit besitzen, während aber die Deckplatte zur Vermeidung eines geringeren Reibwertes aus einem vulkanisierten Kautschuk bestehen soll. Die Schwierigkeiten beim Herstellen derartiger Förderbänder aus verschiedenen Elastomeren, nämlich aus hochpolymerem Polyvinylchlorid einerseits und aus natürlichem oder synthetischem Naturkautschuk oder dessen Derivaten andererseits, liegen darin, daß sich diese beiden Materlalgruppen schlecht miteinander verbinden lassen. Die verschiedenen Bahnen haften nicht oder nur schwer direkt aufeinander und lösen sich ab. Es ist versucht worden, die Verbindungsstellen dieser verschiedenen Komponenten durch geeignete Zusätze des einen Produktes zu dem anderen Produkt so weit zu modifizieren, daß doch noch eine Haftung erzielt werden kann. Derartige Maßnahmen sind jedoch ungeeignet oder stoßen auf Schwierigkeiten, da die einzelnen Zwischenmischungen genau aufeinander abgestimmt werden müssen. So z. B. ist ein der vorliegenden Erfindung entgegengesetztes Problem bekannt, bei welchem ein Kautschukkörper mit einer PVC-Deckplatte oder Deckschicht versehen wird und eine Chlorkautschukklebelösung zum Verbinden dieser beiden an sich unverträglichen Materialien allerdings ohne Beseitigung der obenerwähnten Nachteile verwendet wird. Es sind ferner Förderbänder bekannt, deren Lauffläche aus Kautschuk und deren Tragflächen aus einem thermoplastischen Kunststoff, z. B. Polyvinylchlorid besteht. Bei diesen Förderbändern trennen sich die Deckplatten sowohl an den seitlichen Verbindungsstellen Kautschuk/Kunststoff als auch gegenüber dem Kern. For certain special purposes and especially for conveyor belts in mining operations it is desirable to have only the core consisting of fabric sheets with layers of polyvinyl chloride to connect, as the fabric sheets impregnated with polyvinyl chloride have better properties regarding flame retardancy, strength, dielectric strength and work capacity own, while the cover plate to avoid a lower coefficient of friction should consist of a vulcanized rubber. The difficulties in making such conveyor belts made of different elastomers, namely of high polymer Polyvinyl chloride on the one hand and made from natural or synthetic natural rubber or its derivatives on the other hand, lie in the fact that these two groups of materials badly connect with each other. The various tracks do not stick or difficult to stack directly on top of each other and detach. An attempt has been made to the connection points of these various components by adding suitable additives to one product Modify the other product to such an extent that adhesion is still achieved can be. However, such measures are unsuitable or encounter difficulties because the individual intermediate mixes have to be precisely matched to one another. So z. B. a problem opposite to the present invention is known at which a rubber body is provided with a PVC cover plate or cover layer and a chlorinated rubber adhesive solution for bonding them both inherently incompatible Materials, however, is used without eliminating the disadvantages mentioned above. Conveyor belts are also known whose running surface is made of rubber and their supporting surfaces made of a thermoplastic material, e.g. B. consists of polyvinyl chloride. With these Conveyor belts separate the cover plates at both the lateral connection points Rubber / plastic as well as towards the core.

Diese Nachteile sollen durch die vorliegende Erfindung beseitigt werden. Als Deckplatte wird nunmehr ein Schichtgebilde verwendet, welches aus einer Gewebebahn besteht, die auf der einen Seite, und zwar auf der Innenseite, mit dem Material, z. B. These disadvantages are intended to be eliminated by the present invention will. A layer structure is now used as the cover plate, which consists of a Fabric web is made on one side, namely on the inside, with the Material, e.g. B.

Polyvinylchlorid kaschiert oder belegt ist, welches auch zum Verbinden der den Kern bildenden Gewebebahnen benutzt wird, während auf der Außenseite dieser Deckplattenbahn das andere Deckplattenmaterial, z. B. Kautschuk, verwendet wird, welches sich sonst nur schlecht mit dem ersten Material verbindet. Bei einer derartigen Deckplattenbahn wirkt die in der Mitte liegende Gewebebahn als Verankerungsschicht für beide Materialien. Um nun an der Stoßstelle, die sich in Bahnrichtung bildet, eine gute Verbindung zu gewährleisten, wird ein Streifen untergelegt, welcher dasselbe Material enthält, welches zum Verbinden der Gewebebahnen in Kern und für die Innenbeschichtung der Deckplattenbahn verwendet wurde, nämlich Polyvinylchlorid.Polyvinyl chloride is laminated or covered, which is also used for connecting of the fabric webs forming the core, while on the outside of this Cover sheet sheet the other cover sheet material, e.g. B. rubber, is used, which otherwise only connects poorly with the first material. With such a The fabric sheet in the middle of the cover sheet acts as an anchoring layer for both materials. In order to now at the joint that forms in the direction of the web, To ensure a good connection, a strip is placed underneath, which is the same Contains material which is used to connect the fabric panels in the core and for the inner coating the cover sheet was used, namely polyvinyl chloride.

Die vorliegende Erfindung betrifft somit ein Verfahren zum Herstellen eines mehrschichtigen Förderbandes mit einem Kern aus mit Polyvinylchloridschichten verbundenen Gewebebahnen und einer Gummideckplattenbahn. Zum Herstellen dieser mehrschichtigen Förderbänder wird gemäß der Erfindung so vorgegangen, daß eine auf einer Seite mit einer Gummideckplatte und auf der anderen Seite mit einer Polyvinylchloridschicht versehene Deckplattenbahn hergestellt, diese um einen etwa halb so breiten Kern aus mit Polyvinylchlorid verbundenen Gewebebahnen gelegt und nach Unterlegen der Stoßstelle mit einem Polyvinylchlorid enthaltenden Streifen der so aufgebaute Rohling auf bekannte Weise unter Druck und Wärme verpreßt wird. Vorzugsweise kann das erfindungsgemäße Verfahren dahingehend abgewandelt werden, daß die einzelnen mit Polyvinylchlorid imprägnierten Gewebebahnen des Kernes gleichzeitig mit der umgelegten Deckplattenbahn und dem Streifen unter der Stoßstelle unter Druck und Wärme verpreßt werden. Das nach dem Verfahren gemäß der Erfindung erhaltene Förderband hat dann die gewünschte Deckplattenbahn aus einem vulkanisierten Kautschuk und besteht im Kern aus den üblichen Gewebebahnen, die durch Polyvinylchloridschichten verbunden sind. Die Haftung der andersartigen Außenschicht am Kern ist ausgezeichnet und selbst mehrmonatige Beanspruchung und Walkarbeit zeigten keine Schäden. The present invention thus relates to a method of manufacture a multi-layer conveyor belt with a core made of polyvinyl chloride layers connected fabric sheets and a rubber cover sheet. To make this multilayer Conveyor belts is proceeded according to the invention so that one on one side with a rubber cover plate and on the other side with a polyvinyl chloride layer provided cover sheet made, this around a core about half as wide made of fabric webs connected with polyvinyl chloride and placed under the Joint with a strip containing polyvinyl chloride, the blank thus constructed on known Way is compressed under pressure and heat. Preferably, the inventive Process can be modified in that the individual with polyvinyl chloride impregnated fabric webs of the core simultaneously with the folded cover plate web and the strip under the joint under pressure and heat. That Conveyor belt obtained by the method according to the invention then has the desired one Cover sheet made of a vulcanized rubber and consists in the core of the usual Fabric webs connected by layers of polyvinyl chloride. The liability of Different kind of outer layer on the core is excellent and even several months of use and flexing showed no damage.

Im folgenden soll die Erfindung an Hand eines Ausführungsbeispiels im Zusammenhang mit der Zeichnung näher erläutert werden; es zeigt Fig. 1 einen Schnitt durch das nach dem erfindungsgemäßen Verfahren hergestellte fertige Förderband, F i g. 2 einen Schnitt durch die zur Herstellung des Förderbandes verwendete Deckplattenbahn. In the following, the invention is based on an exemplary embodiment are explained in more detail in connection with the drawing; 1 shows a Section through the finished conveyor belt produced by the method according to the invention, F i g. 2 shows a section through the cover plate web used to manufacture the conveyor belt.

In jedem Fall wird zuerst eine übliche Gewebebahn 2 mit einer Kautschukdeckplatte 4 und einer Polyvinylchloridschicht 6 verpreßt, um die Deckplattenbahn zu erhalten. Diese Deckplattenbahn 8 wird dann um einen Kern gelegt, welcher aus Gewebebahnen 10 und Zwischenschichten 12 aus Polyvinylchlorid besteht. Die Deckplattenbahn 8 muß etwa doppelt so breit sein wie die Kernbahn, so daß erstere ohne Schwierigkeiten um die Kernbahn gelegt werden kann, wobei sie diese einhüllt. Die Stoßstelle 14 wird mit einem Polyvinylchlorid enthaltenden Streifen 16 unterlegt, welcher beim späteren Verpressen unter Wärme und Druck nur mit den entsprechenden Polyvinylchloridschichten in Verbindung gelangt, und zwar einmal mit der obersten Polyvinylchloridschicht der Kernbahn und zum anderen mit der Innenschicht der ebenfalls aus Polyvinylchlorid bestehenden Deckplattenbahn. Durch das anschließende Verpressen unter Wärme und Druck wird ein einheitliches Gebilde erhalten, wobei der Klebstreifen 16 kaum in Erscheinung tritt. In any case, a conventional fabric sheet 2 with a rubber cover plate is first used 4 and a layer of polyvinyl chloride 6 pressed to obtain the cover sheet. This cover plate web 8 is then placed around a core, which is made of fabric webs 10 and intermediate layers 12 made of polyvinyl chloride. The cover sheet 8 must be about twice as wide as the core web, so that the former without difficulty can be placed around the core web, enveloping it. The joint 14 is underlaid with a strip 16 containing polyvinyl chloride, which at later pressing under heat and pressure only with the corresponding polyvinyl chloride layers comes into contact, once with the top layer of polyvinyl chloride the core web and on the other hand with the inner layer which is also made of polyvinyl chloride existing cover sheet. The subsequent pressing under heat and A uniform structure is obtained under pressure, the adhesive strip 16 hardly being in Appearance occurs.

Man kann natürlich auch so vorgehen, daß man die mit Polyvinylchlorid kaschierten Gewebebahnen für den Kern in noch nicht verpreßtem Zustande auf dem Arbeitstisch über der oder auf die Deckplattenbahn auslegt, die letztere dann an den überstehenden Enden umschlägt und dann nach Unterlegen des Klebstreifens den so aufgebauten Rohling auf einmal unter Druck und Wärme verpreßt. Ein derartiges Vorgehen ist sehr viel vorteilhafter, da man die schweren Bahnen nur einmal handhaben muß und weiterhin beim Verpressen einen Preßvorgang einspart. One can of course also proceed in such a way that one uses the polyvinyl chloride laminated fabric webs for the core in a not yet pressed state on the The work table is laid out over or on the cover sheet, the latter then on folds over the protruding ends and then, after placing the adhesive strip underneath, the so constructed blank is pressed at once under pressure and heat. Such a thing The procedure is much more advantageous because you only have to handle the heavy tracks once must and continue to save a pressing process when pressing.

Selbstverständlich ist es auch möglich, die Deckplattenbahn auch nur zusammenzulegen und dann mit dem Kern oder den Kernbahnen gemeinsam zu verpressen. Selbstverständlich kann die in Bahnrichtung verlaufende Stoßkante auch an anderen Stellen des Förderbandes liegen, und es können schließlich sogar zwei verschiedene Stoßstellen vorhanden sein. Of course, it is also possible to use the cover sheet as well only to be folded up and then pressed together with the core or the core webs. Of course, the abutting edge running in the direction of the web can also be used on others Make the conveyor belt lie, and it can end up being two different ones Butt joints are present.
