Description
Transportsystem für Werkzeuge Gebiet der ErfindungTransport system for tools Field of the invention
Die Erfindung betrifft ein Transportsystem für Werkzeuge gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a transport system for tools according to the preamble of claim 1.
An Pressen, Stanzmaschinen und ähnlichen Vorrichtungen sind meist Transporteinrichtungen zum Wechseln von Werkzeugen angebracht. Im allgemeinen handelt es sich dabei um mindestens einen Träger, der sich von der Maschine weg erstreckt. Zum Wechsel schwerer Werkzeuge sind auf diesem Träger Rollen angebracht, um die Bewegung des Werkzeugs zu erleichtern.Presses, punching machines and similar devices usually have transport devices for changing tools. This generally consists of at least one support that extends away from the machine. Rollers are attached to this support to facilitate the movement of the tool when changing heavy tools.
Bei bisherigen Transporteinrichtungen sind diese Rollen ortsfest drehbar gelagert. Meist werden zur Lagerung Wälzlager verwendet. Da beim oft ungleichmäßigen oder schrägen Aufsetzen des Werkzeuges große Kräfte auf die Rollenlager wirken, werden diese Lager häufig beschädigt und ein Austausch wird erforderlich.In previous transport systems, these rollers are mounted in a fixed position and can rotate. Rolling bearings are usually used for the bearings. Since large forces act on the roller bearings when the tool is often placed unevenly or at an angle, these bearings are often damaged and replacement is necessary.
Ziel der Erfindung ist es, ein Transportsystem für Werkzeuge zu schaffen, das robuster gegenüber punktuellen hohen Belastungen ist.The aim of the invention is to create a transport system for tools that is more robust against high localized loads.
Erfindungsgemäß wird diese Aufgabe gemäß dem kennzeichnenden Teil des Anspruches 1 gelöst.According to the invention, this object is achieved according to the characterizing part of claim 1.
Die Bewegung des Werkzeugs erfolgt hier nicht auf ortsfesten Rollen, sondern auf mindestens einer linear beweglich geführten Kette, die aus miteinander verbundenen Rollen besteht, wie z.B. eine Rollenkette. Der vertikal wirkende Kraftanteil wird durch die RollenThe movement of the tool does not take place on stationary rollers, but on at least one linearly movable chain, which consists of interconnected rollers, such as a roller chain. The vertically acting force component is transmitted by the rollers
direkt auf eine sich unter den Rollen befindliche Auflagefläche geleitet, ohne dabei ein Rollenlager zu belasten.directly onto a support surface located beneath the rollers without placing any strain on a roller bearing.

Fig. 3 zeigt eine -Seitenansicht der Transportkette, Fig. 4 zeigt die Transportkette von oben.Fig. 3 shows a side view of the transport chain, Fig. 4 shows the transport chain from above.
Die statische Basis des erfindungsgemäßen Transportsystems ist ein Träger 1, der mittels Befestigungsvorrichtungen 2 an der entsprechenden Maschine befestigt ist. Die Endloskette 3 wird mittels zweier Umlenkrollen 4 so geführt, daß ein Teil der zur Kette 3 gehörenden Rollen 6 auf einer Auflagefläche 5 aufliegt. Der Abschnitt, an dem die Rollen 6 auf der Auflagefläche 5 aufliegen, bildet die Transportstrecke. Die Auflagefläche 5 besteht vorzugsweise aus einem gehärteten Metall oder ist mit einem harten Material oder Metall beschichtet. Die Achsen 9 der Rollen 6 sind mit ihren nächsten Nachbarn mit Verbindungsgliedern 7 verbunden. Die als Laufrollen ausgebildeten Rollen 6 sind vorzugsweise so dimensioniert, daß jede einzelne Rolle das gesamte oder fast das gesamte Gewicht eines zu transportierenden Werkzeugs tragen kann. Die Rollen 6 sind seitlich durch eine Führungseinrichtung 8 geführt.The static basis of the transport system according to the invention is a carrier 1, which is attached to the corresponding machine by means of fastening devices 2. The endless chain 3 is guided by means of two deflection rollers 4 in such a way that part of the rollers 6 belonging to the chain 3 rest on a support surface 5. The section on which the rollers 6 rest on the support surface 5 forms the transport path. The support surface 5 is preferably made of a hardened metal or is coated with a hard material or metal. The axes 9 of the rollers 6 are connected to their nearest neighbors by connecting links 7. The rollers 6 designed as rollers are preferably dimensioned in such a way that each individual roller can bear the entire or almost the entire weight of a tool to be transported. The rollers 6 are guided laterally by a guide device 8.
Die Lager, die benötigt werden, um die Rollen 6 drehbar in den Verbindungsgliedern 7 zu lagern, können in Form der Achsen 9 sehr einfach gestaltet sein, da sie keinen großen Belastungen ausgesetzt werden. Es treten in diesen Lagern keine vertikalen Kräfte auf, sondern nur horizontale Kräfte, die durch den Rollwiderstand und durch Beschleunigungskräfte bedingt sind, welche jedoch mindestens eine Größenordnung kleiner sind als die typischerweise auftretenden vertikalen Kräfte.The bearings required to support the rollers 6 in the connecting links 7 can be designed very simply in the form of the axles 9, since they are not subjected to great loads. No vertical forces occur in these bearings, only horizontal forces caused by rolling resistance and acceleration forces, which are, however, at least an order of magnitude smaller than the vertical forces that typically occur.
Abhängig von der Breite der Rollen und der Größe der zu transportierenden Werkzeuge, kann ein einzelner Träger 1 zum Transport der Werkzeuge genügen. Im allgemeinen werden jedoch wenigstens zwei parallel verlaufende Träger 1 benötigt, um auch größere Werkzeuge sicher transportieren zu können.Depending on the width of the rollers and the size of the tools to be transported, a single carrier 1 may be sufficient to transport the tools. In general, however, at least two parallel carriers 1 are required in order to be able to transport larger tools safely.
Das oben beschriebene Prinzip ist natürlich nicht nur für stationär an einer Maschine befestigte Transportsysteme verwendbar. Es kann auch an schienengebundenen oder frei verfahrbaren Werkzeugladewagen, an Übergabebrücken oder dergleichen angewendet werden.The principle described above is of course not only applicable to transport systems that are stationary attach to a machine. It can also be used on rail-mounted or freely movable tool loading wagons, on transfer bridges or the like.
