Definitions

  • This disclosure is directed towards an apparatus comprising a coupling arrangement and a method of controlling such an apparatus.
  • Machines particularly those in construction, mining, earth moving, goods handling, forestry, agriculture or other such industries, typically utilise a tool controlled by an operator to perform work.
  • a variety of tools may be attached to an arm arrangement of a multipurpose machine via a coupling arrangement for performing different types of work.
  • the coupling arrangement may comprise a quick coupler, which allows coupling and decoupling of a tool and machine in a particularly efficient and quick operation.
  • the quick coupler is typically controlled by an operator from a cab of the machine via a control system and associated actuators.
  • the coupling arrangement may further comprise an intermediate element located between the arm arrangement and tool.
  • the element may comprise a tiltrotator, which enables controlled rotation of the work tool about a rotational axis and controlled tilting of the work tool relative to a tilt axis.
  • WO2014/168540 discloses a method of controlling a tiltrotator attached by a quick coupler to a tool and attached by pins to an arm arrangement.
  • the quick coupler is unlocked and locked based upon two checking procedures in two separate control units.
  • the method only relates to the control of the quick coupler between the tiltrotator and tool.
  • the present disclosure provides an apparatus in accordance with claim 1.
  • the present disclosure further provides a method in accordance with claim 10.
  • the present disclosure is generally directed towards the control of a first quick coupler located between an arm arrangement of a machine and an intermediate element and the control of a second quick coupler for coupling the intermediate element and a tool. It is desirable that it is clear, particularly to an operator located in a cab of the machine, whether the first or second quick coupler should be engaged or disengaged during operation. This prevents, for example, an operator disengaging the first quick coupler rather than the second quick coupler. It also prevents the operator from unintentionally releasing the intermediate element and tool simultaneously.

  7. Vorrichtung (9) nach Anspruch 5 oder Anspruch 6, wobei das mindestens eine zweite Kupplungselement (36) der ersten Schnellkupplung (31) eingerichtet ist, um selektiv in mindestens ein Armkupplungselement (70) der Armanordnung (14) der Maschine einzugreifen, um die erste Schnellkupplung (31) selektiv mit der Armanordnung (14) der Maschine (10) zu kuppeln.
  8. Vorrichtung (9) nach einem der Ansprüche 5 bis 7, wobei die zweite Schnellkupplung (32) mindestens ein zweites Kupplungselement (39) umfasst, wobei das mindestens eine zweite Kupplungselement (39) der zweiten Schnellkupplung (32) eingerichtet ist, um selektiv in mindestens ein Werkzeugkupplungselement (41) des Werkzeugs (15) einzugreifen, um das Zwischenelement (30) selektiv mit dem Werkzeug (15) zu kuppeln.
  9. Vorrichtung (9) nach einem der vorstehenden Ansprüche, wobei das Zwischenelement (30) eine Werkzeugausrichtungsvorrichtung umfasst.
  10. Verfahren zum Betreiben einer Vorrichtung (9), wobei die Vorrichtung (9) eine Eingabevorrichtung und eine Kupplungsanordnung (11) umfasst, umfassend ein Zwischenelement (30) und eine erste Schnellkupplung (31) zum selektiven Kuppeln des Zwischenelements (30) mit einer Armanordnung (14) einer Maschine (10), wobei das Zwischenelement (30) eine zweite Schnellkupplung (32) zum selektiven Kuppeln eines Werkzeugs (15) mit dem Zwischenelement (30) umfasst, wobei die erste und zweite Schnellkupplung (31, 32) jeweils selektiv betätigungsfähig sind, um das Zwischenelement (30) an der Armanordnung (14) der Maschine (10) bzw. dem Werkzeug (15) zu verriegeln, wobei das Verfahren umfasst:
    Empfangen einer Eingabe in die Eingabevorrichtung; und
    gekennzeichnet ist durch
    Ermitteln an einer Maschinensteuereinheit, ob das Zwischenelement (30) mit der Armanordnung (14) der Maschine (10) gekuppelt ist; und
    als Reaktion auf das Eingangssignal Beschränken der Entriegelung der ersten Schnellkupplung (31), wenn festgestellt wird, dass das Zwischenelement (30) mit der Armanordnung (14) der Maschine (10) gekuppelt ist, dadurch gekennzeichnet, dass die Maschinensteuereinheit derart programmiert ist, dass die Maschinensteuereinheit nicht in der Lage ist, die erste Schnellkupplung (31) als Reaktion auf eine Eingabe von der Eingabevorrichtung zu betätigen, wenn festgestellt wird, dass das Zwischenelement (30) derart mit der Armanordnung (14) gekuppelt ist, dass eine erste Kupplung (33) manuell durch einen Bediener entriegelt werden muss, um das Zwischenelement (30) von der Maschine (10) zu entkuppeln.
  11. Verfahren nach Anspruch 10 oder Anspruch 11, wobei das Ermitteln, ob die erste Schnellkupplung (31) oder die zweite Schnellkupplung (32) verriegelt oder entriegelt werden soll, auf einem Ermitteln beruht, ob das Zwischenelement (30) durch die erste Schnellkupplung (31) mit der Armanordnung (14) der Maschine (10) gekuppelt ist.
  12. Verfahren nach einem der Ansprüche 10 bis 12, ferner als Reaktion auf das Feststellen, dass das Zwischenelement (30) mit der Armanordnung (14) der Maschine (10) gekuppelt ist, umfassend:
    Beibehalten der ersten Schnellkupplung (31) in einer verriegelten Konfiguration, um das Zwischenelement (30) mit der Maschine (10) gekuppelt zu halten; und
    Verriegeln oder Entriegeln der zweiten Schnellkupplung (32).
