Gemäß einer Ausführungsform kann die Speichervorrichtung 22 die Kapseln einer oder mehreren Zuführkammern 24, 26 zuführen, die wiederum die Kapseln ersten und zweiten Dosierrädern 28, 30 zuführen. Gemäß einer Ausführungsform umfasst die Zuführkammer 24 und/oder die Zuführkammer 26 eine "Ein-Ebenen"-Zuführkammer ("single-plane"), die nur eine einzige Ebene Kapseln dem Umfang der jeweiligen Dosierräder 28, 30 zuführt. Beispielsweise können die Kapseln, die durch die "Ein-Ebenen"-Zuführkammer gelangen, auf eine Anordnung begrenzt sein, die mehrere Kapseln hoch ist und mehrere Kapseln tief, aber nur eine einzige Kapsel breit. Gemäß einer alternativen Ausführungsform (nicht gezeigt), kann die Speichervorrichtung 22 die Kapseln einer Zuführkammer, anstelle von zwei wie gezeigt, zuführen, und die Zuführkammer kann wiederum die Kapseln einem einzigen Dosierrad oder mehreren Dosierrädern zuführen. Die Speichervorrichtung 22 und/oder die Zuführkammern 24, 26 können Rüttler oder ähnliche Einrichtungen umfassen, die dabei helfen, die Kapseln von der Speichervorrichtung 22 zu den Dosierrädern 28, 30 zu bewegen.In one embodiment,
Mit Bezug auf
Gemäß einer Ausführungsform können die Dosierradtaschen 32, 34 im Wesentlichen eine zylindrische Form aufweisen und können einen Durchmesser und ausreichende Tiefe aufweisen, um alle oder einen Teil der jeweiligen Kapseln aufzunehmen. Im Falle einer zylindrischen Form können die Taschen eine Tiefe und einen Durchmesser aufweisen, die gleich oder leicht größer sind, als der Durchmesser der jeweiligen Kapseln, um eine präzise Positionierung der Kapseln innerhalb der Taschen zu gewährleisten. Gemäß alternativen Ausführungsformen können die Dosierradtaschen 32, 34 quadratisch, rechtwinklig, konisch sein oder andere im Fachgebiet bekannte Formen aufweisen, vorausgesetzt, die Taschen können alle oder einen Teil der jeweiligen Kapseln sicher und präzise aufnehmen. Eine Vakuumquelle (nicht gezeigt) kann an die Taschen 32, 34 angelegt werden, um bei der Übertragung der Kapseln von den Zuführkammern 24, 26 zu helfen und/oder beim Halten der Kapseln innerhalb der Taschen 32, 34 zu helfen, nachdem sie einmal dort sind.In one embodiment, metering wheel pockets 32, 34 may be substantially cylindrical in shape and may have a diameter and sufficient depth to receive all or a portion of the respective capsules. In the case of a cylindrical shape, the pockets may have a depth and a diameter equal to or slightly greater than the diameter of the respective capsules to ensure precise positioning of the capsules within the pockets. In alternative embodiments, metering wheel pockets 32, 34 may be square, rectangular, conical, or other shapes known in the art, provided that the pockets can safely and precisely receive all or a portion of the respective capsules. A vacuum source (not shown) may be applied to the

Mit Bezug auf
Für die Dosierradtaschen, die von den Dosierführungen 44, 46 abgedeckt sind, kann die Vakuumquelle, die normalerweise an die Dosierradtaschen 32, 34 angelegt wird, ausgeschaltet und/oder durch einen Luftstrom ersetzt werden, der aus den abgedeckten Dosierradtaschen 32, 34 heraus gerichtet ist. Sobald eine der Dosierradtaschen 32, 34 hinter die Dosierführung 44, 46 dreht und nicht länger von ihr blockiert wird, kann der Luftstrom die Kapsel aus der Dosierradtasche und in die Zwischenradtasche 40, 42 treiben, die zu dem Zeitpunkt in Kontakt mit ihr steht. Folglich können die Dosierführungen 44, 46 ermöglichen, dass der Luftstrom, der die Kapseln aus den Taschen bläst, früher eingesetzt wird, als wenn es keine Dosierführungen 44, 46 gäbe, ohne das Risiko, dass die Kapseln aus den Dosierradtaschen 32, 34 vorzeitig ausgestoßen werden. Folglich können die Geschwindigkeit und Konsistenz verbessert werden, bei der Kapseln von den Dosierradtaschen 32, 34 zu den Zwischenradtaschen 40, 42 übertragen werden.For the metering wheel pockets covered by the metering guides 44, 46, the vacuum source normally applied to the metering wheel pockets 32, 34 may be switched off and / or replaced by an airflow directed out of the covered metering wheel pockets 32, 34 , As soon as one of the metering wheel pockets 32, 34 rotates behind the

Die Anordnung der zuvor beschriebenen Dosierräder 28, 30, Zwischenräder 36, 38 und Einlegeräder 50 kann helfen, den schnelleren Betrieb der Objekt-Einlegevorrichtung 10 zu ermöglichen. Beispielsweise können die Dosierräder 28, 30 bei einer relativ langsamen Geschwindigkeit arbeiten (zum Beispiel gemessen an den Außenumfängen 28a, 30a), um die konsistente Übertragung der Kapseln von den Zuführkammern 24, 26 zu den jeweiligen Dosierradtaschen 32, 34 zu gewährleisten. Gleichzeitig kann das Einlegerad 50 für eine schnelle Produktionsrate die Kapseln bei einer hohen Zufuhrgeschwindigkeit in das Filtermaterial einlegen.The arrangement of the previously described
Gemäß einer Ausführungsform kann eine Teilungs- oder Abstandserweiterung und Geschwindigkeitserhöhung bei der Übertragung von den Dosierrädern 28, 30 zu den Zwischenrädern 36, 38 auftreten. Beispielsweise können gemäß einer Ausführungsform die ersten und zweiten Zwischenräder 36, 38 schneller rotieren als die jeweiligen Dosierräder 28, 30. Zusätzlich oder alternativ können die Zwischenradtaschen 40, 42 mit einer größeren Teilung angeordnet sein als die Dosierradtaschen 32, 34.According to one embodiment, a pitch or pitch extension and speed increase may occur in the transmission from the
Gemäß einer Ausführungsform können schnellere Geschwindigkeiten bereitgestellt werden, indem Kapseln von den ersten und zweiten Zwischenradtaschen 40, 42 zu den Einlegeradtaschen 52 abwechselnd übertragen werden. Beispielsweise kann eine Zwischenradtasche 40 in dem ersten Zwischenrad 36 eine Kapsel zu einer Einlegeradtasche 52 übertragen, und nachfolgend kann eine Zwischenradtasche 42 in dem zweiten Zwischenrad 38 ein Kapseln zu der direkt nächsten Einlegeradtasche 52 übertragen, und so weiter. Eine Teilungserhöhung und/oder eine Geschwindigkeitserhöhung kann auch bei der Übertragung von den Zwischenrädern 36, 38 zu dem Einlegerad 50 auftreten. Gemäß einer Ausführungsform können das erste Zwischenrad 36, das zweite Zwischenrad 38 und das Einlegerad 50 bei im Wesentlichen der gleichen Geschwindigkeit rotieren, obgleich andere Ausgestaltungen möglich sind. Beispielsweise könnte das Einlegerad 50 alternativ schneller oder langsamer drehen als die ersten und zweiten Zwischenräder 36, 38.In one embodiment, faster speeds may be provided by alternately transferring capsules from the first and second idler pockets 40, 42 to the inserter bump pockets 52. For example, an
Die nachfolgende Tabelle führt beispielhafte Parameter für den Betrieb einer Objekt-Einlegevorrichtung 10 auf:
Bei der Verwendung zum Bilden von 108 mm Filterstäben, die vier Kapseln pro Filter aufweisen, führte eine Ausführungsform der Objekt-Einlegevorrichtung 10, die die zuvor genannten Parameter anwendet, zu einer Maschinengeschwindigkeit von ungefähr 216 m Filtermaterial pro Minute, mit einem Ausstoß von 2000 Filtern pro Minute (8000 Kapseln pro Minute). Ein Fachmann wird aus dieser Beschreibung erkennen, dass auch andere Parameter verwendet werden können als die zuvor beschriebenen.When used to form 108 mm filter rods having four capsules per filter, one embodiment of the

Um die genaue Platzierung der Kapsel C in dem Filtermaterial zu ermöglichen, kann die Einlegeradtasche 52 die Kapsel C stützen, so dass ein Teil C1 der Kapsel C, beispielsweise zwischen ungefähr einem Viertel und ungefähr einer Hälfte des Kapselvolumens im Inneren der Tasche 52 sitzt, wobei der Rest C2 der Kapsel C aus der Tasche 52 über dem Außenumfang 50a des Einlegerads 50 hervorsteht. Folglich kann das Einlegerad 50 die Kapsel manuell im Wesentlichen in ihre gewünschte Position innerhalb des Filtermaterials einlegen, ohne auf Gebläseluft zurückzugreifen, um die Kapsel C aus einer tiefen Tasche heraus und in ihre gewünschte Position zu "schießen", was zu einer höheren Kontrolle und Genauigkeit bei der Platzierung der Kapsel C führt und/oder höhere Betriebsgeschwindigkeiten erlaubt.To facilitate accurate placement of the capsule C in the filter material, the
