Description
Die vorliegende Erfindung bezieht sich auf eine Verpackungsmaschine mit einem Maschinenrahmen und zwei Werkzeughälften, wobei mindestens eine der Werkzeughälften durch einen Verriegelungsmechanismus an dem Maschinenrahmen verriegelbar ist und die andere Werkzeughälfte in einer Hubrichtung zu der verriegelbaren Werkzeughälfte hin bewegbar ist.The present invention relates to a packaging machine having a machine frame and two tool halves, wherein at least one of the tool halves is lockable to the machine frame by a locking mechanism and the other tool half is movable toward the lockable tool half in a stroke direction.
Herkömmliche Verpackungsmaschinen haben zwei oder vier Verriegelungsmechanismen. Diese bewirken eine Verriegelung an den Außenkanten der verriegelbaren Werkzeughälfte in der Hubrichtung. Hierbei tritt eine Wechsellast beim Schließen des Werkzeugs bzw. beim Siegeln auf. Das Werkzeug hängt an seinen Außenkanten und wird dann beim Siegeln mit einer Flächenlast im Zentrum aufgebogen. Insgesamt haben derartige Verpackungsmaschinen Nachteile aufgrund einer erhöhten Reibung und eines erhöhten Abriebs zwischen Werkzeug und Maschinenseite. Der Teileaufwand ist relativ hoch und die Beherrschung der mehrfachen Toleranzen ist schwierig. Darüber hinaus ist die Werkzeuglänge fest vorgegeben. Die herkömmlichen Verriegelungsmechanismen müssen regelmäßig gereinigt werden, da für Verpackungsmaschinen zum Verpacken von Lebensmitteln hohe Hygieneanforderungen gestellt werden.Conventional packaging machines have two or four locking mechanisms. These cause a locking at the outer edges of the lockable tool half in the stroke direction. In this case, an alternating load occurs when closing the tool or when sealing. The tool hangs on its outer edges and is then bent open during sealing with a surface load in the center. Overall, such packaging machines have disadvantages due to increased friction and increased abrasion between the tool and the machine side. The parts cost is relatively high and mastering the multiple tolerances is difficult. In addition, the tool length is fixed. The conventional locking mechanisms must be cleaned regularly because of the high hygiene requirements for packaging machines for food packaging.

Ein Ausführungsbeispiel einer Verpackungsmaschine gemäß der Erfindung wird anhand einer Schalenverschließmaschine, auch Traysealer genannt, unter Bezugnahme auf die
Die
Die
Die Siegelvorrichtung 21 ist mit dem Maschinenrahmen 1 verbunden. Die Siegelvorrichtung 21 hat zwei Werkzeughälften 2, 3, von denen die obere Werkzeughälfte 2 im dargestellten Ausführungsbeispiel durch einen einzigen Verriegelungsmechanismus 4 an dem Maschinenrahmen 1 verriegelbar ist. Die Siegelvorrichtung 21 hat des weiteren das Hubwerk 9, das die andere Werkzeughälfte 3 in einer Hubrichtung zu der verriegelbaren Werkzeughälfte 2 bewegt.The sealing
Die
Der Verriegelungsmechanismus 4 hat des weiteren einen einzigen Riegel 6 in Gestalt eines Bolzens 6, der an dem Maschinenrahmen 1 vorgesehen ist und in die Aufnahme 5 der verriegelbaren Werkzeughälfte 2 einführbar ist, um die verriegelbare Werkzeughälfte 2 an dem Maschinenrahmen 1 zu verriegeln. Der Bolzen 6 ist an der rechten Seite der
Bei dem dargestellten Ausführungsbeispiel ist die Aufnahme 5 im wesentlichen im Schwerpunkt der verriegelbaren Werkzeughälfte 2 angeordnet. In vorteilhafter Weise ist eine derartige Verriegelung unabhängig von der Werkzeuglänge und -breite. Darüber hinaus wird die verriegelbare Werkzeughälfte 2 sehr gut zentriert. Des weiteren ist der Raum an den Außenseiten der verriegelbaren Werkzeughälfte 2 frei, so dass die Siegelvorrichtung 21 kompakt ist. Durch die mittige Verriegelung wird darüber hinaus eine weitere Durchbiegung der verriegelbaren Werkzeughälfte 2 verringert.In the illustrated embodiment, the
Ein Ende 6a des Bolzens 6, das in die Aufnahme 5 einzuführen ist, ist konisch ausgebildet. Zusätzlich hat die Aufnahme 5 vorzugsweise eine abgeschrägte Umfangsfläche 5a. In vorteilhafter Weise wird dadurch die verriegelbare Werkzeughälfte 2 sicher an dem Maschinenrahmen 1 verriegelt. Darüber hinaus sind die Toleranzen einfach zu beherrschen, wobei Beanspruchungen und Ungenauigkeiten durch Wärmedehnung der verriegelbaren Werkzeughälfte 2 minimiert werden können. Die Zentrierung der verriegelbaren Werkzeughälfte 2 wird durch das konische Ende 6a des Bolzens 6 weiter vereinfacht.One
Vorzugsweise ist die Aufnahme 5 austauschbar an der verriegelbaren Werkzeughälfte 2 angebracht und aus einem Material ausgebildet ist, das weicher ist als das Material des Bolzens 6. Dadurch ist die Aufnahme 5 in vorteilhafter Weise das einzige Verschleißteil und kann einfach ausgetauscht werden.Preferably, the
Des weiteren sind Anlageabschnitte 7 an der verriegelbaren Werkzeughälfte 2 für eine definierte Anlage der verriegelbaren Werkzeughälfte 2 an dem Maschinenrahmen 1 vorgesehen. Dadurch nimmt die verriegelbare Werkzeughälfte 2 stets eine definierte Lage ein, die durch Spannkräfte des Verriegelungsmechanismus 4 nicht oder nur gering geändert wird. Alternativ können die Anlageabschnitte 7 am Maschinenrahmen 1 vorgesehen sein.Furthermore,
Auch wenn dies nicht in den Zeichnungen dargestellt ist, können die Werkzeughälften 2, 3 über eine Zentriervorrichtung zum Zentrieren der verriegelbaren Werkzeughälfte 2 an der anderen Werkzeughälfte 3 verfügen. Die Zentriervorrichtung kann durch Vorsprünge gebildet sein, die an einer Werkzeughälfte 2, 3 vorgesehen sind und in entsprechende Ausnehmungen in der anderer Werkzeughälfte 2, 3 geführt werden. Die Werkzeughälften 2, 3 können auch jeweils mit dem Maschinenrahmen 1 zentriert werden.Although not shown in the drawings, the tool halves 2, 3 may have a centering device for centering the
Auch wenn dies in den Zeichnungen nicht dargestellt ist, hat die verriegelbare Werkzeughälfte 2 elektrische Anschlüsse und Fluidanschlüsse, die mit entsprechenden elektrischen Anschlüsse und Fluidanschlüssen des Maschinenrahmens 1 verbunden sind, wenn die verriegelbare Werkzeughälfte 2 an dem Maschinenrahmen 1 verriegelt ist. An der Schnittstelle der elektrischen Anschlüsse und der Fluidanschlüssen sind geeignete Dichtungen vorgesehen.Although not shown in the drawings, the
Bei dem dargestellten Ausführungsbeispiel wird der Bolzen 6 durch den Pneumatikzylinder 8 betätigt. Dadurch kann in vorteilhafter Weise eine große und dauerhafte Verriegelungskraft bereit gestellt werden. Alternativ kann auch ein Hydraulikzylinder verwendet werden. Zur Entriegelung ist es erforderlich, dass der Zylinder 8 angesteuert wird und mit einem gewissen Kraftaufwand aus der Aufnahme 5 heraus gezogen wird. Das Lösen der Verriegelungskraft kann demnach nur aktiv erfolgen, indem der Zylinder 8 angesteuert wird. Im drucklosen Zustand stellt der Zylinder 8 zwar keine Verriegelungskraft bereit, die verriegelbare Werkzeughälfte 2 kann jedoch nicht herunter fallen.In the illustrated embodiment, the
Der Betrieb des Verriegelungsmechanismus 4, der zum Beispiel bei einem Werkzeugwechsel durchgeführt wird, ist folgendermaßen:The operation of the
Zunächst werden die Werkzeughälften 2, 3 in der Siegelvorrichtung 21 in ihren abgesenkten Positionen angeordnet. Dabei befindet sich die Aufnahme 5 der verriegelbaren Werkzeughälfte 2 lotrecht unter der Hubstrecke des Bolzens 6. Dabei kann die Zentriervorrichtung verwendet werden, um die verriegelbare Werkzeughälfte 2 an die andere Werkzeughälfte 3 zu zentrieren.First, the tool halves 2, 3 are arranged in the
Im nächsten Schritt werden beide Werkzeughälften 2, 3 durch das Hubwerk 9 angehoben, bis der Bolzen 6 der Aufnahme 5 zugewandt ist. Daraufhin wird der Bolzen 6 durch Ansteuern des Pneumatikzylinders 8 in die Aufnahme 5 eingeführt, um die verriegelbare Werkzeughälfte 2 an dem Maschinenrahmen 1 zu verriegeln und/oder zu zentrieren. Danach kann die andere Werkzeughälfte 3 durch das Hubwerk 9 abgesenkt werden.In the next step, both
Die Entnahme der verriegelbaren Werkzeughälfte 2 geschieht in der umgekehrten Reihenfolge. Dabei wird die andere Werkzeughälfte 3 durch das Hubwerk an die verriegelbare Werkzeughälfte 2 angehoben. Danach erfolgt die Freigabe zur Entriegelung, so dass der Bolzen 6 aus der Aufnahme 5 heraus bewegt werden kann. Die verriegelbare Werkzeughälfte 2 liegt nun mittels ihres Gewichtes auf der anderen Werkzeughälfte 3 auf. Das Hubwerk wird mit beiden Werkzeughälften 2, 3 abgesenkt, und die Werkzeughälften 2, 3 können aus der Siegelvorrichtung 21 entnommen werden.The removal of the
Die vorliegende Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt, sondern es sind viele Abwandlungen denkbar.The present invention is not limited to the illustrated embodiment, but many modifications are conceivable.
