Abstract
Description
Der Anmeldegegenstand betrifft den Verpackungsmaschinenbau und dort einen Antriebsmechanismus für gegeneinander bewegbare Schweißbacken an vertikalen Schlauchbeutelmaschinen.Of the The subject of the application relates to packaging machine construction and there a drive mechanism for mutually movable welding jaws on vertical flow wrappers.
Vertikale Schlauchbeutelmaschinen und horizontale Beutelmaschinen sind hinlänglich bekannt. Sie dienen zum Abfüllen von Produkt in Beutel. Zum Verschweißen des Beutelmaterials werden gegeneinander bewegbare Schweißbacken eingesetzt, die ein Folienmaterial zwischen sich einklemmen und derart verschweißen.vertical Tubular bag machines and horizontal bag machines are well known. she serve for bottling from product to bag. To weld the bag material mutually movable welding jaws used, which clamp a film material between them and such weld.

Die bekannte Vorrichtung hat den Nachteil, dass sie relativ sperrig ist, da die Teile der beiden Linearmotoren (elektromagnetischen Linearantriebe) separat ausgeführt sind.The known device has the disadvantage that it is relatively bulky is because the parts of the two linear motors (electromagnetic Linear actuators) separately are.
Es liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen.It the object is to eliminate this disadvantage.
Gelöst ist die Aufgabe gemäß dem kennzeichnenden Teil des Anspruchs 1. Danach sind die beiden Sekundärteile miteinander über eine magnetische Abschirmung verbunden und bilden derart eine Baueinheit.Solved is the Task according to the characterizing Part of claim 1. Thereafter, the two secondary parts with each other via a connected magnetic shield and thus form a structural unit.
Die vorgeschlagene Neuerung hat den Vorteil, dass zwei Sekundärteile baulich zusammengefasst werden, wodurch eine kompakte Bauweise erreicht wird. Um eine dadurch auftretende Störung deren Funktion zu verhindern, wird zwischen den Sekundärteilen eine magnetische Abschirmung vorgesehen. Diese kann aus einem elektrisch leitfähigen Material, insbesondere einem Metall, ausgeführt werden. Dabei darf das Material nicht magnetisierbar sein. Zum einen kann eine derartige Verbindung derart gemeint sein, dass die Magnete der separaten Sekundärteile auf gegenüberliegenden Seiten der Abschirmung montiert werden. Zum anderen kann eine separate Halterung für die Sekundärteile vorgesehen sein, und die für beide Sekundärteile wirkende Abschirmung trennt lediglich diese Teile.The proposed innovation has the advantage that two secondary parts structurally be summarized, which achieves a compact design becomes. In order to prevent a disturbance occurring thereby their function, is between the secondary parts provided a magnetic shield. This can be from an electric conductive material, in particular a metal. This may be the Material should not be magnetizable. On the one hand, such Connection be meant so that the magnets of the separate secondary parts opposite Sides of the shield are mounted. On the other hand, a separate a Mount for the secondary parts be provided, and for both secondaries acting shield separates only these parts.
Vorteilhafte Ausgestaltungen der vorgeschlagenen Vorrichtung sind in den Ansprüchen 2 bis 9 beschrieben.advantageous Embodiments of the proposed device are in the claims 2 to 9 described.
Sind die Sekundärteile parallel zueinander ausgerichtet (Anspruch 2), so können durch eine Relativbewegung der Linearmotoren unterschiedliche Bewegungsabläufe in einer Richtung erzeugt werden, um die Schweißbacken zu bewegen. Sind dagegen gemäß Anspruch 3 die Sekundärteile in einem rechten Winkel zueinander ausgerichtet und bilden sie derart ein Kreuz, so können senkrecht zueinander unterschiedliche bzw. miteinander kombinierte Bewegungen eines Backenstocks erzeugt werden, insbesondere um einerseits den Backenstock zu heben und zu senken, und um andererseits dabei die Schweißbacken zu öffnen und zu schließen.are the secondary parts aligned parallel to each other (claim 2), so can by a relative movement of the linear motors different movements in one Direction are generated to move the welding jaws. Are against it according to claim 3 the secondaries aligned at a right angle to each other and form them a cross, so can perpendicular to each other different or combined with each other Movements of a jaw stock are generated, in particular on the one hand to raise and lower the cheek stick, and on the other hand the welding jaws to open and close.
Ein weiterer Vorteil der kompakten Baueinheit als Antriebselement für die Schweißbacken ist seine Verzugsstabilität, wenn die Sekundärteile auf unterschiedlichen Seiten der als Halterung dienenden Abschirmung (Anspruch 6) befestigt sind. Derart gleichen sich die auf gegenüberliegenden Seiten der Abschirmung befestigten Sekundärteile bezüglich ihrer Neigung infolge eigener Erwärmung die Abschirmung zu krümmen, aus. Die Baueinheit bleibt auch bei hoher Leistung und entsprechender Erwärmung der Sekundärteile ohne nennenswerten Verzug. Als magnetische Abschirmung eignen sich nicht magnetisierbare Leichtmetalle, wie Aluminium und Magnesium (Anspruch 4), wodurch die bewegbare Baueinheit zudem relativ leicht wird. Auch kann die Abschirmung gleich der Halterung sein, wodurch ein Bauteil eingespart wird.One Another advantage of the compact unit as a drive element for the welding jaws is its default stability, if the secondaries on different sides of serving as a holder shield (Claim 6) are attached. So are the same on opposite Side of the shield attached secondary parts with respect to their inclination own warming to bend the shield, out. The assembly remains at high power and corresponding Warming the secondaries without significant delay. As a magnetic shield are suitable non-magnetisable light metals, such as aluminum and magnesium (Claim 4), whereby the movable assembly also relatively easy becomes. Also, the shield may be the same as the holder, whereby a component is saved.
Um, insbesondere bei einer einseitigen Anbringung der beiden Sekundärteile an einer Halterung, eine Krümmung der Halterung infolge einer Erwärmung der Sekundärteile und dadurch eine Schwergängigkeit der Vorrichtung zu vermeiden, wird vorgeschlagen, als Sekundärteil eine Aneinanderreihung separater Sekundärteilsegmente vorzusehen, wobei jeder Sekundärteilsegment über eine Befestigung mit einer Halterung des Sekundärteils verbunden ist (Anspruch 5). Die in der Praxis vorkommenden Fertigungsungenauigkeiten von wenigen Mikrometern, wobei die Sekundärteilsegmente noch dicht aneinander anliegen, oder genau vorgegebene Spalte zwischen den Sekundärteilsegmenten (Anspruch 7) führen dann dazu, dass bei herkömmlicher Verschraubung oder teilweiser Verklebung der Sekundärteilsegmente eine erwärmungsbedingte, relativ starke Längenausdehnung der Sekundärteilsegmente nicht zu einer Krümmung der Halterung des Sekundärteils führt. Als Befestigung eignen sich Schrauben, Nieten und Klebstoffe (Anspruch 8).Around, in particular in a one-sided attachment of the two secondary parts a holder, a curvature the bracket due to heating of the secondary parts and thus a binding To avoid the device is proposed as a secondary part Provide juxtaposition of separate secondary segment segments, wherein each abutment segment via a fixture connected to a holder of the secondary part is (claim 5). The manufacturing inaccuracies occurring in practice of a few micrometers, with the secondary segment still close together abutment, or exactly predetermined gap between the abutment segments (Claim 7) lead then to that with conventional screwing or partial bonding of the secondary part segments a heating-related, relatively long extension the secondary part segments not to a curvature the holder of the secondary part leads. Suitable fasteners are screws, rivets and adhesives (claim 8th).
Die Vorrichtung kann Teil einer vertikalen Schlauchbeutelmaschine oder einer horizontalen Beutelmaschine sein (Anspruch 9).The Device can be part of a vertical flow wrapper or a horizontal bag machine (claim 9).
