Description

Beim Herstellen von Stahlband- und Bandeisenverbindungen mittels bekannter Verschlußmaschinen wird das überlappte Stahlband rein mechanisch entweder mittels Überschiebhülse und seitlicher Einkerbung oder ohne Überschiebhülse mithin sich schließenden Einkerbungen geschlossen, wobei nicht nur ein hochwertiges Stahlband benutzt werden muß, sondern wobei auch eine erhebliche Schwächung des Stahlbandquerschnittes durch die Einkerbungen auftritt. Diese Stahlbandschwächung verursacht auf dem Transport der so gebundenen Materialien größere Störungen, die durch Reißen des Stahlbandes oder durch Öffnen des Stahlbandverschlusses hervorgerufen werden können. When making steel band and iron band connections by means of known sealing machines, the overlapped steel strip is either purely mechanical by means of a slip-on sleeve and lateral notch or without a slip-on sleeve closing notches closed, with not just a high-quality steel band must be used, but also a considerable weakening of the steel strip cross-section occurs through the notches. This weakening of the steel belt causes during transport the materials bonded in this way have major disruptions caused by the tearing of the steel belt or can be caused by opening the steel strap fastener.

Diese Nachteile der bekannten Verschluß arten werden gemäß der Erfindung beseitigt und dabei wesentliche wirtschaftliche Vorteile erzielt. Die Verbindung der Bandenden wird an Stelle von Kerben mittels elektrischer Punktschweißung vorgenommen, die in bekannter Weise eine innige metallische Verbindung der beiden Bandenden vornimmt. These disadvantages of the known types of closure are according to the invention eliminated and thereby achieved significant economic advantages. The connection the tape ends are made instead of notches by means of electrical spot welding, which makes an intimate metallic connection between the two ends of the tape in a known manner.

Solche durch elektrisches Schweißen hergestellte Bandverbindungen haben den Vorteil, daß die zu verwendenden Stahlbänder von wesentlich schwächerer Dimension sein können als bei den übrigen Verbindungsverfahren, wodurch erhebliche Einsparungen an Material eintreten, und daß außerdem die Haltbarkeit der Verbindungen besser und durch mehrfaches Punktschweißen hintereinander in Längsrichtung des Bandes unter normalen Bedingungen fast unzerstörbar ist. Die im Moment der Verbindung der Bandenden vorhandene Spannung des Stahlbandes bleibt beim Punktschweißverfahren unverändert, wohingegen sie sich bei anderen Verbindungsarten nach Abschluß des Kerbvorganges vermindert, was eine Lockerung des Bandes zur Folge hat. Diese letztgenannten Vorteile sind besonders wichtig beim Bündeln von Braunkohlenbriketts, die langen Transporten mit öfterem Umladen unterliegen. Zu diesen Vorteilen tritt noch hinzu, daß das Punktschweißen schneller und mit wesentlich geringerem menschlichem Kraftaufwand als das Herstellen einer Verbindung mittels Einkerben des Stahlbandes durchgeführt werden kann. Es wird somit eine erhöhte Leistung der- -Arbeiter und damit eine Verbilligung erzielt. Such tape connections made by electrical welding have the advantage that the steel belts to be used are much weaker Dimension than with the other connection methods, which means considerable Savings in material occur, and that also the durability of the connections better and by multiple spot welding one after the other in the longitudinal direction of the strip is almost indestructible under normal conditions. The moment of connection of the The tension of the steel strip that is present at the ends of the strip remains in the spot welding process unchanged, whereas with other connection types they change after the completion of the Notching process reduced, which has a loosening of the band as a result. The latter Advantages are especially important when bundling lignite briquettes that are long Transports with frequent reloading are subject to. In addition to these advantages, that spot welding is faster and requires much less human effort than making a connection by notching the steel belt can be. It is thus an increased performance of the workers and thus cheaper achieved.

Um das Punktschweißverfahren durchführen zu können, wird bei den bekannten Verschlußapparaten an Stelle der Kerbeinrichtung eine Punktschweißvorrichtung eingebaut, die mit einem oder mehreren Schweißkontakten ausgestattet ist. In order to be able to carry out the spot welding process, the known closure devices in place of the notch device a spot welding device built-in, which is equipped with one or more welding contacts.

Eine Einrichtung, wie sie zum Beispiel zum Bündeln vonBraunkohlenbriketts besonderer Form, die durch ein überlapptes Stahlband zusammengehalten werden, benutzt wird, ist in der Zeichnung dargestellt, und zwar zeigt Abb. I die Vorrichtung quer zu dem zusammenschweißenden Band F, Abbi 2 in Richtung des in Abb. I angegebenen Pfeiles a. A device such as that used, for example, for bundling lignite briquettes special shape, which are held together by an overlapped steel band is shown in the drawing, namely Fig. I shows the device transversely to the band F to be welded together, Fig. 2 in the direction of that indicated in Fig. I. Arrow a.

Die Einrichtung besteht aus einem schmiedeeisernen StänderA und der Grundplatte B Auf diese sind aufmontiert die Spannvorrichtung C und die Bandabschervorrichtung D und zwischen diesen beiden die Schweißvorrichtung E. The device consists of a wrought iron standA and the Base plate B The tensioning device C and the tape cutting device are mounted on this D and between these two the welding device E.

Die Einrichtung arbeitet wie folgt: Nachdem das Band F durch die Spannvorrichtung C angespannt und durch die Abschervorrichtung D auf die richtige Länge gebracht worden ist, erfolgt die Punktschweißung durch die Abwärtsbewegung des Kontakte-s G, wobei beim DurcEdrücken d!es Exzenterhebels H die Kontakte I und K eines Schweißzeitbegrenzers geschlossen werden. Die Schweißung erfolgt gleichzeitig oder nacheinander an einem oder mehreren Punkten. Der Strom, der durch die beiden Kabelzuführungen L und M zugeführt wird, bewirkt die Schweißung. Die Schweißzeit ist durch einen Schweißzeitbegrenzer festgelegt. The device works as follows: After the belt F through the Clamping device C clamped and by the shearing device D on the correct one Has been brought length, the spot welding is done by the downward movement of the contacts G, whereby when the eccentric lever H is pressed down, the contacts I and K of a welding time limiter can be closed. The welding takes place at the same time or one after the other at one or more points. The current that runs through the two Cable feeds L and M is fed, causes the weld. The welding time is determined by a welding time limiter.
