Pref. the middle portion of the joint is first vulcanised then the two bordering zones. The method enables smaller plant to be used for a given size of belt.

Description

Verfahren zum Verbinden zweier Enden eines Fördergurtes Die Erfindung betrifft ein Verfahren zum Verbinden zweier Fördergurtenden, deren zugfeste Einlagen aus Seilen bestehen, durch Vulkanisation, und ein Vulkanisiergerät zur Durchführung des Verfahrens. Method for connecting two ends of a conveyor belt The invention relates to a method for connecting two conveyor belt ends, their tensile inserts consist of ropes, through vulcanization, and a vulcanizing device to carry out of the procedure.

Bei den bisher üblichen Verfahren zum Verbinden zweier Enden eines Fördergurtes durch Vulkanisation wird ein Vulkanisiergerät benutzt, das in Längs- und Querrichtung größer ist als die zu vulkanisierende Fläche, so daß zur Herstellung der Verbindung nur eine Vulkanisation erforderlich ist. Die zum Verbinden von breiten und hochfesten Gurten geeigneten Vulkanisiergeräte sind sehr schwer und sehr aufwendig. Ferner ist die für die Vulkanisation erforderliche elektrische Leistung so groß, daß bei der Herstellung von Fördergurtverbindungen auf Baustellen Schwierigkeiten auftreten.In the previously common method for connecting two ends one Conveyor belt through vulcanization, a vulcanizing device is used, which is and transverse direction is greater than the area to be vulcanized, so that for manufacture the connection only requires vulcanization. The one for joining broads Vulcanizing devices suitable for high-strength belts are very heavy and very expensive. Furthermore, the electrical power required for vulcanization is so great that that difficulties in the production of conveyor belt connections on construction sites appear.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Verbinden zweier Fördergurtenden zu entwickeln, das mit; einem verhält;nismL:ig leichten und handlichen Vulkanisiergerät durchzuführen ist und das sich auch zur Anwendung auf Baustellen eignet.The invention is based on the object of a method for connecting to develop two conveyor belt ends with; a behaved; nismL: ig light and handy vulcanizing device is to be carried out and that is also applicable to Suitable for construction sites.

Die Lösung der gestellten Aufgabe besteht in erster Linie darin, daß die Vulkanisation der Verbindungsstelle abschnittsweise erfolgt, wobei es zweckmäßig ist, daß zunächst der mittlere Teil der Verbindungsstelle vulkanisiert wird und dann die sich daran anschließenden Teile.The solution to the problem is primarily that the vulcanization of the connection point takes place in sections, it being expedient is that first the middle part of the joint is vulcanized and then the adjoining parts.

Nach einem weiteren Schritt der'Erfindung wird die Vulkanisation der sich an den mittleren Teil der Verbindungsstelle anschließenden Teile jeweils gleichzeitig durchgeführt. Dadurch wird die Zeit für die Herstellung einer Verbindung wesentlich verkuerzt, Ein weiteres Merkmal der Erfindung besteht darin, daß während des Vulkanisationsvorganges die unvulkanisiert bleibenden angrenzenden Abschnitt des Fördergurtes gekühlt werden Die abschnittsweise Vulkanisation einer Verbindungsstelle wurde bisher nicht für durchführbar gehalten, weil innerhalb der Verbindungslänge nur unvulkanisierter Gummi eingesetzt wird und demzufolge die bei der Vulkanisation auftretenden Druckverhältnisse innerhalb des tmvulkanisierten erhitzten Gummis nicht anders zu beherrschen sind als bei gleichzeitiger Vulkanisation der ganz-en.Verbindungsstelle, da dann der in der Verrbindunvsstelle auftretende Langsdruck von den berdenvulkanisierten Gurtenden aufgefangen wird. Um diese Schwierigkeiten zu vermeiden, wird in weiterer Ausgestaltung der Erfindung nur der Gummi, der sich nach der Vulkanisation zwischen den Seilen sowie unmittelbar unter- und oberhalb der Seile befindet, unvulkanisiert in die Verbindungsstelle eingebracht, während für die Deckplatten ausvulkanisierter Gumml,verwendet wird, wobei die Deckplatten an ihrer den Seilen zugewandten Seite so vorbereitet sind, daß'sie sich mit dem unvulkanisierten Gummi gut verbinden. Durch diese Maßnahme bleibt der Vulkanisationsdruck entsprechend der wesentlich geringeren Gummimenge so gering, daß Verschiebungen innerhalb der Verbindung beim Vulkanisationsvorgang nicht auftreten.After a further step of the invention, the vulcanization of the parts adjoining the middle part of the connection point at the same time carried out. This makes the time required to establish a connection essential abbreviated, Another feature of the invention is that during the vulcanization process the adjacent section of the conveyor belt that remains unvulcanized is cooled The section-wise vulcanization of a connection point has not yet been used for kept feasible because only unvulcanized within the connection length Rubber is used and consequently the pressure conditions that occur during vulcanization cannot otherwise be controlled within the vulcanized, heated rubber than with simultaneous vulcanization of the entire joint, since then the Longitudinal pressure occurring in the connection point from the vulcanized belt ends is caught. In order to avoid these difficulties, a further development the invention only the rubber that is between after vulcanization the ropes and immediately below and above the ropes, unvulcanized introduced into the connection point, while vulcanized for the cover plates Gumml, is used, with the cover plates on their side facing the ropes are prepared so that they bond well with the unvulcanized rubber. By this measure, the vulcanization pressure remains essential in accordance with smaller amount of rubber so small that displacements within the connection when Vulcanization process does not occur.

Um eine gute Verbindung zwischen der ausvuikanisierten Deckplatte des Fördergurtes und der unvulkanisiert in die Verbindungsstelle eingelegten Deckplatte zu erzielen, wird an den vier Stoßkanten der Verbindung ein Streifen unvulkanisierten Gummis eingelegt.To ensure a good connection between the vulcanized cover plate of the conveyor belt and the unvulcanized cover plate inserted into the connection point To achieve this, a strip is unvulcanized on the four joint edges of the joint Inlaid rubbers.

Für die Durchführung des erfindungsgemäßen Verfahrens wird zweckmäßigerweise ein Vulkanisiergerät verwendet, bei dem die Länge der Heizplatte etwas größer ist als die halbe Verbindungslänge. Die Heizplatte ist gemäß einem weiteren Merkmal der Erfindung zweiteilig ausgebildet.For carrying out the process according to the invention, it is expedient a vulcanizing device is used in which the length of the heating plate is slightly larger than half the link length. The heating plate is according to a further feature of the invention formed in two parts.

Anhand der Zeichnung ist die Erfindung näher erläutert. Es zeigen: Fig. 1 eine Draufsicht auf die Verbsindungsstelle eines Fördergurtes mit in der Mitte aufliegender geteilter Heizplatte, Fig. 2 eine Draufsicht auf die Verbindungsstelle eines Pördergurtes. mit in den Randzonen aufliegenden Teilen der Heizplatte, Fig. 3 einen Längsschnitt durch eine Verbindungsstelle und Pig. 4 einen Schnitt nach der Linie IV-IV in Fig. 3.The invention is explained in more detail with the aid of the drawing. Show it: Fig. 1 is a plan view of the connection point of a conveyor belt with in the Split heating plate lying in the middle, FIG. 2 shows a plan view of the connection point a conveyor belt. with parts of the heating plate resting in the edge zones, Fig. 3 shows a longitudinal section through a connection point and Pig. 4 a section after the line IV-IV in FIG. 3.

Auf die in den Fig. 1 und 2 dargestellte Verbindung der Enden 1 und 2 eines Fördergurtes ist eine aus den Teilen 3 und 4 bestehende geteilte Heizplatte aufgelegt. Die in Fig. 1 dargestellte Anordnung entspricht dem ersten Vulkanisationsvorgang, während die in Fig. 2 dargestellte Anordnung dem zweiten Nulkanisationsvorgang entspricht. In Fig. 2 ist die Lage der geteilten Heizplatte während des ersten Vulkanisationsvorgangs mit strichpunktierten Linien angedeutet. Dadurch ist zu erkennen, daß beim zweiten Vulkanisationsvorgang die Teile 3 und 4 der geteilten Heizplatte nicht nur einen schmalen Bereich -5 des ausvulkanisierten Fördergurtes überdecken, sondern auch einen schmalen Bereich 6 des Bereichs der Verblndungsstelle, der beim ersten Vulkanisationsvorgang ausvulkanisiert worden ist. Während des ersten Vulkanisationsvorgangs werden die Außenkanten der aus den Teilen 3 und 4 bestehenden Heizplatte gekühlt und während des zweiten Vulkanisationsvorgangs die Innenkanten der aus den Teilen 3 und 4 bestehenden Heizplatte.On the connection of the ends 1 and 2 shown in FIGS 2 of a conveyor belt is a divided heating plate consisting of parts 3 and 4 hung up. The arrangement shown in Fig. 1 corresponds to the first vulcanization process, while the arrangement shown in FIG. 2 corresponds to the second vulcanization process. In Fig. 2 is the position of the split heating plate during the first vulcanization process indicated with dash-dotted lines. This shows that the second Vulcanization process the parts 3 and 4 of the split heating plate not just one cover narrow area -5 of the fully vulcanized conveyor belt, but also a narrow area 6 of the area of the junction, the has been fully vulcanized during the first vulcanization process. During the first The outer edges of the parts 3 and 4 will be the vulcanization process Heating plate cooled and the inner edges during the second vulcanization process the heating plate consisting of parts 3 and 4.

Es ist auch möglich, die Heizplatten beim zweiten Vulkanisationsvorgang gegeneinander auszutauschen. In diesem Fall muß Jede Platte nur an einer Seite eine Kühlzone besitzen.It is also possible to use the heating plates during the second vulcanization process to exchange for each other. In this case, each plate only needs to have one on one side Own cooling zone.

Die in den Fig. 3 und 4 dargestellte Fördergurtverbindung besteht aus Fördergurtenden 7 und 8 mit darin eingebetteten Seilen 9 und 10. Der unmittelbar zwischen den Seilen sowie unmittelbar unter- und oberhalb der Seile vorhandene Gummi 11 sowie die an den vier Stoßkanten der Verbindung angeordneten Streifen 12 bestehen aus unvulkanisiertem Gummi, während die Deckplatten 13 und 14 aus ausvulkanisiertem Gummi bestehen.The conveyor belt connection shown in FIGS. 3 and 4 exists from conveyor belt ends 7 and 8 with embedded ropes 9 and 10.
