Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum schnellen Ein- und Ausbringen einer Anfahrkette beim Formatwechsel in einer Stranggiessanlage.The present invention relates to a method and a device for the rapid introduction and removal of a start-up chain when changing formats in a continuous caster.

Das Manipulieren von Anfahrketten beim Formatwechsel in Stranggiessanlagen ist eine mühselige und mit räumlichen Problemen verbundene Angelegenheit, die obendrein zeitraubend ist. Zeitverluste sind jedoch in der Stranggiesstechnik unbedingt zu vermeiden, da sie sich nicht nur im Hinblick auf die Produktivität auswirken, sondern zu ernsten Störungen der Funktionstüchtigkeit der Anlage selbst führen können.The manipulation of start-up chains when changing the format in continuous casting plants is a tedious matter and involves spatial problems, which is also time-consuming. However, time losses in continuous casting technology must be avoided as they do not only have an impact on productivity, but can also lead to serious malfunctions in the functionality of the system itself.

Selbstverständlich ist, dass man deshalb mehrere Anfahrketten vorsieht, die mit Köpfen von unterschiedlichem Format versehen sind und dass man die Anfahrketten in Magazinen zum Einsatz bereithält.It goes without saying that there are therefore several start-up chains with heads of different formats and that the start-up chains are available for use in magazines.

Magazine für Anfahrketten nehmen jedoch wegen der oft grossen Länge der Ketten Platz in Anspruch und sowohl das Einbringen von Ketten nach Gebrauch, als das Ausbringen neuer Ketten aus dem Magazin sind umständliche Arbeiten, die Zeitverluste mit sich bringen.However, magazines for start-up chains take up space due to the often great length of the chains, and both the insertion of chains after use and the removal of new chains from the magazine are cumbersome tasks that involve loss of time.

Das Ziel der Erfindung besteht darin, ein Verfahren vorzuschlagen, das ein schnelles Ein- und Ausbringen von Anfahrketten ermöglicht und das die Giessfolgezeit durch Verkürzen der Rüstzeit verringert, sowie die hierzu erforderliche Vorrichtung.The aim of the invention is to propose a method which enables a quick introduction and removal of start-up chains and which reduces the casting time by shortening the set-up time, as well as the device required for this.

Dieses Ziel wird erreicht durch das erfindungsgemässe Verfahren nach Anspruch 1.This goal is achieved by the inventive method according to claim 1.

Wie man sieht, werden erfindungsgemäss nur die eigentlichen Anfahrteilstücke der Kette gelagert, während praktisch immer das gleiche Reststück verwendet werden kann, um eine betriebsbereite Anfahrkette darzustellen.As can be seen, according to the invention only the actual start-up sections of the chain are stored, while practically always the same remaining piece can be used to represent an operational start-up chain.

Zum Trennen der Anfahrkette 1,0 in das Anfahrteilstück 1,5 und das Reststück 1,1 verfährt man die Anfahrkette in den Führungenn 1,9 und 1,4 so, dass das zu entkoppelnde Kettenglied sich unmittelbar vor einem festen Kupplungsmechanismus 1,10 befindet. Umgekehrt wird man zum Ankuppeln eines Anfahrteilstückes 1,5 an das Reststück 1,1, ersteres in der Führung 1,4 und letzteres in der Führung 1,9 individuell so gegeneinander verfahren, dass die zu koppelnden Endglieder sich unmittelbar vor einem festen Kupplungsmechanismus 1,10 befinden. Letzterer kann automatisch oder auch manuell betrieben werden.To separate the start-up chain 1.0 into the start-up section 1.5 and the remainder 1.1, the start-up chain is moved in the guides 1.9 and 1.4 in such a way that the chain link to be decoupled is located directly in front of a fixed coupling mechanism 1.10 . Conversely, to couple a start-up section 1.5 to the remaining section 1.1, the former in the guide 1.4 and the latter in the guide 1.9 are moved individually so that the end members to be coupled are directly in front of a fixed coupling mechanism 1, 10 are located. The latter can be operated automatically or manually.

Die Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens ist dadurch gekennzeichnet, dass zum Eingringen der Anfahrkette 1,0 in Ruhestellung in einer Führung 1,9, diese eine schwenkbare Rampe 1,2 aufweist, wobei zum Bewegen der Anfahrkette 1,0 bzw. des Reststückes 1,1 ein mit einer Winde 1,11 verbundenes Seil 1,12 durch die Führung 1,9 und die Rampe 1,2 reicht und mit dem Kettenende 1,1 verbunden ist, während eine Führung 1,4 die Verlängerung der eingeschwenkten Rampe 1,2 bildet, die zum Bewegen des anzukuppelnden bzw. abgekoppelten Anfahrteilstückes 1,5 mit einer Treibvorrichtung 1,3 versehen ist, wobei das freie Ende der Führung 1,4 an ein Greifer-Hub-Transportsystem 1,6/1,7/1,8 angrenzt.The device for carrying out the method according to the invention is characterized in that in order to insert the starting chain 1.0 in the rest position in a guide 1.9, the guide has a pivotable ramp 1.2, with moving the starting chain 1.0 or the remaining piece 1 1, a rope 1.12 connected to a winch 1.11 passes through the guide 1.9 and the ramp 1.2 and is connected to the chain end 1.1, while a guide 1.4 extends the pivoted-in ramp 1, 2, which is provided for moving the start-up section 1.5 to be coupled or uncoupled with a drive device 1.3, the free end of the guide 1.4 being connected to a gripper-stroke transport system 1.6 / 1.7 / 1, 8 adjacent.

Die Greifer-Hub-Transportanordnung 1,6/1,7/1,8 hat eine Zangenvorrichtung 1,6 zum Greifen des Anfahrkettenkopfes, welche über Seile mit einer Windevorrichtung 1,7 verbunden ist, wobei letztere an einem Fahrgestell 1,8 befestigt ist. Letzteres ist auf Schienen angeordnet, die in einen verfahrbaren Wechselwagen 2,1 münden. Dieser dient zum Transport der Anfahrteilstücke direkt in das Magazin bzw. heraus.The gripper-stroke transport arrangement 1.6 / 1.7 / 1.8 has a tongs device 1.6 for gripping the start-up chain head, which is connected to a winch device 1.7 by means of ropes, the latter being fastened to a chassis 1.8 . The latter is arranged on rails which open into a movable change carriage 2.1. This is used to transport the start-up sections directly into or out of the magazine.

Das Fahrgestell 1,8 sowie der Wechselwagen 2,1 sind mit automatisch arbeitenden Übernahme- bzw. Übergabemechanismen zum Manipulieren der Anfahrteilstücke 1,5 versehen.The chassis 1.8 and the change carriage 2.1 are provided with automatically operating takeover or transfer mechanisms for manipulating the start-up sections 1.5.

Der Hauptvorteil der Erfindung besteht offensichtlich darin, dass man praktisch zu jedem Zeitpunkt ein einsatzbereites Reststück in Ruhestellung zur Verfügung hat, das auf schnellstem Wege mit einem geeigneten Teilstück, welches vollautomatisch aus dem Magazin herbeigeschafft wird, zu einer betriebsbereiten Einheit zusammengefügt werden kann und dies innerhalb einer Vorrichtung, die sich dank der bogenförmigen Führungen durch Platzersparnis auszeichnet.The main advantage of the invention is obviously that you have a ready-to-use remnant at rest at practically any time, which can be quickly combined with a suitable section that is automatically brought from the magazine to an operational unit, and within a device that is characterized by space savings thanks to the curved guides.

Weitere Vorteile gehen aus der Beschreibung der Funktionsweise der Vorrichtung hervor und zwar wird anhand der Zeichnungen das Einbringen einer Anfahrkette nach Gebrauch beschrieben. In den Zeichnungen stellt Fig. 1 einen Schnitt durch eine bevorzugte Form der erfindungsgemässen Vorrichtung dar, in der die bogenförmigen Führungen sowie der Greifer-Hub-Transportmechanismus gezeigt werden, während die Fig. 2 über besagten Mechanismus hinaus das Magazin, sowie den Wechselwagen darstellt.Further advantages emerge from the description of the mode of operation of the device and that the introduction of a starting chain after use is described with reference to the drawings. In the drawings, FIG. 1 shows a section through a preferred form of the device according to the invention, in which the curved guides and the gripper-stroke transport mechanism are shown, while FIG. 2 shows the magazine and the change carriage in addition to said mechanism.

Wie aus Fig. 1 ersichtlich, wird die Anfahrkette 1,0 deren Ende 1,1 unten rechts gezeigt wird, in die Führung 1,9 hineingezogen, was mit Hilfe des Seiles 1,12 über die Seilwinde 1,11 erfolgt, bis das Kettenende 1,1 in seiner Endposition oben rechts, vor der Umlenkrolle des Seiles anlangt. Zum Einfahren wurde die schwenkbare Rampe 1,2 nach unten ausgeschwenkt. Sie wird nun wieder rückgefahren, bis sie eine Verlängerung der zweiten bogenförmigen Führung 1,4 bildet. Die Anfahrkette 1,0 wird sodann mit Hilfe ihres Eigengewichtes und der sich auf der schwenkbaren Rampe 1,2 befindlichen Treibrollenvorrichtung 1,3 so verfahren, dass sie teilweise in die Führung 1,4 hineinragt.As can be seen from FIG. 1, the starting chain 1.0, the end 1.1 of which is shown at the bottom right, is drawn into the guide 1.9, which is done with the aid of the cable 1.12 via the cable winch 1.11 until the chain end 1.1 in its end position at the top right, in front of the pulley of the rope. The swiveling ramp 1, 2 was swung down to retract. It is now retracted again until it forms an extension of the second arcuate guide 1.4. The starting chain 1.0 is then moved with the aid of its own weight and the drive roller device 1.3 located on the pivotable ramp 1.2 so that it partially projects into the guide 1.4.

Nun erfolgt die Trennung des Anfahrkettenteilstückes 1,5 von der Anfahrkette 1,0 durch die Entkupplungsvorrichtung 1,10. Das Reststück 1,1 der Anfahrkette 1,0 bleibt in der eingenommenen Position, während das Teilstück 1,5 mit Hilfe der Treibvorrichtung 1,3 soweit in das Bogensegment 1,4 gefahren wird, dass es von der sich in abgesenkter Position «A» befindlichen hydraulisch betätigten Zangenvorrichtung 1,6 übernommen werden kann.Now the starting chain section 1.5 is separated from the starting chain 1.0 by the decoupling device 1.10. The remaining piece 1.1 of the starting chain 1.0 remains in the assumed position, while the partial piece 1.5 is moved into the curved segment 1.4 with the aid of the driving device 1.3 to the extent that it is in the lowered position “A” located hydraulically operated pliers device 1.6 can be taken over.

Mit Hilfe eines Seilwindwerkes 1,7, welches in einem fahrbaren Wagen 1,8 untergebracht ist, wird das Anfahrkettenteilstück 1,5 mit Hilfe der Zangenvorrichtung 1,6 aus dem Bogensegmentstück 1,4 herausgezogen und zwar soweit, bis die Zangenvorrichtung 1,6 ihre angehobene Position «B» erreicht hat. Der Wagen 1,8 wird nun querverfahren bis er im Anfahrkettenwechselwagen 2,1 die Position der entsprechenden Magazinreihe 2,2 für das Anfahrkettenteilstück erreicht hat.With the help of a cable winch 1.7, which is housed in a mobile carriage 1.8, the start-up chain section 1.5 is pulled out of the arch segment piece 1.4 with the aid of the pliers device 1.6, to the extent that the pliers device 1.6 is raised position «B». The car 1.8 is now traversed until it reaches the position of the start-up chain change car 2.1 has reached the corresponding magazine row 2.2 for the start-up chain section.

Der Anfahrkettenwechselwagen 2,1 fährt nun aus seiner Position «A'» in das Magazin 2,2 zur Position «B'». Durch Absenken und Öffnen der Zangenvorrichtung 1,6 wird das betreffende Anfahrkettenstück im Magazin abgelegt.The start-up chain change carriage 2.1 now moves from its position «A '» into the magazine 2.2 to position «B'». By lowering and opening the pliers device 1,6, the start-up chain piece in question is placed in the magazine.

Der Anfahrkettenwechselwagen 2,1 fährt in seine Ausgangsposition «A'» zurück, wo nun der Wagen 1,8 im Anfahrkettenwechselwagen 2,1 soweit verfahren wird, bis er die Magazinreihe erreicht aus der für den anstehenden Formatwechsel ein neues Anfahrkettenteilstück 1,5 entnommen wird.The start chain change carriage 2.1 moves back to its starting position «A '», where the carriage 1.8 in the start chain change carriage 2.1 is moved until it reaches the magazine row from which a new start chain section 1.5 is removed for the upcoming format change .

Das Verfahren zum Einbringen des ausgetauschten Anfahrkettenteilstückes 1,5 in die Anfahrkettenaufnahme erfolgt in umgekehrter Reihenfolge wie vorher beschrieben.The procedure for inserting the replaced start-up chain section 1.5 into the start-up chain receptacle is carried out in the reverse order to that previously described.
