Der Anmeldegegenstand betrifft den Verpackungsmaschinenbau und dort eine vertikale Schlauchbeutelmaschinen.Of the The subject of the application relates to packaging machine construction and there a vertical flow wrapper.
Vertikale Schlauchbeutelmaschinen sind hinlänglich bekannt. Bei Ihnen wird eine Folienbahn von einer Vorratsrolle abgewickelt und mittels einer Formschulter zu einem Folienschlauch umgeformt. Eine Längssiegeleinrichtung dient zum Verschweißen des Folienschlauches in seiner Transportrichtung.vertical Tubular bag machines are well known. With you will a film web unwound from a supply roll and by means of a Form shoulder transformed into a film tube. A longitudinal sealing device serves for welding the film tube in its transport direction.
Eine bekannte, in einer vertikalen Schlauchbeutelmaschine genutzte Vorrichtung zum Verschweißen einer zu einem Folienschlauch umgeformten Folienbahn weist zwei mittels eines Getriebes gegeneinander bewegbare Siegelbacken zum Erzeugen von Quernähten am Folienschlauch auf. Eine Trenneinrichtung dient zum Abtrennen jeweils eines erzeugten Schlauchbeutels vom Folienschlauch. Der Folienschlauch wird mittels eines gegen den Folienschlauch und ein diesen aufnehmendes vertikal ausgerichtetes Füllrohr wirkenden Folienabzugs weitertransportiert. Ein Linearmotor mit einem ortsfesten Teil und einem beweglichen Teil ist zum Öffnen und Schließen der Schweißbacken vorgesehen. Die Schweißbacken sind dazu ausgebildet, in geschlossenem Zustand mit dem nach unten bewegten Folienschlauch mitbewegt zu werden, um zwei Quernähte in diesem zu erzeugen, und dazwischen den Folienschlauch zu durchtrennen, sowie danach in geöffnetem Zustand nach oben bewegt zu werden, um einen nachfolgenden Schweißvorgang ausführen zu können.A known device used in a vertical tubular bag machine for welding a converted into a film tube film web has two by means of a gear against each other movable sealing jaws for generating of cross seams on the film tube. A separator is used for separating each of a generated tubular bag from the film tube. Of the Foil tube is by means of a against the film tube and a this receiving vertically aligned filling tube acting film trigger transported. A linear motor with a stationary part and a moving part is open and closing the welding jaws intended. The welding jaws are designed to be in the closed state with the down Moving film tube to be moved to two transverse seams in this to produce, and in between to cut the film tube, and afterwards in open Condition to be moved up to perform a subsequent welding process can.
Bei der bekannten Schlauchbeutelmaschine dient ein zweiter Linearmotor zum Heben und Senken der Schweißbacken. Zudem ist auch bekannt, lediglich eine Schweißbacke horizontal zu bewegen, und eine gegenläufige Bewegung der anderen Schweißbacke mittels eines Getriebes, z. B. eines Kniehebelmechanismus auszuführen.at the known tubular bag machine is a second linear motor for lifting and lowering the welding jaws. In addition, it is also known to move only one welding jaw horizontally, and an opposite one Movement of the other welding jaw by means of a gear, z. B. to execute a toggle mechanism.
Die bekannte Vorrichtung hat den Nachteil, dass der Aufwand zum Bewegen der Schweißbacken mitsamt deren Vertikalbewegung relativ groß ist, da zwei Linearmotoren eingebaut und versorgt werden müssen.The known device has the disadvantage that the effort to move the welding jaws together with their vertical movement is relatively large, since two linear motors must be installed and supplied.
Es liegt die Aufgabe zugrunde, eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 derart weiterzubilden, dass der technische Aufwand für den Antrieb der Schweißbacken verringert wird.It the object is based, a device according to the preamble of the claim 1 such that the technical complexity of the drive the welding jaws is reduced.
Gelöst ist die Aufgabe gemäß dem kennzeichnenden Teil des Anspruchs 1. Danach erzeugt das bewegliche Teil über ein quer zur Bewegungsrichtung des beweglichen Teils eines einzigen Linearmotors bewegbares Koppelelement eine Bewegungskomponente quer zur Bewegungsrichtung des beweglichen Teils, um sowohl das Heben und Senken der Schweißbacken als auch das Öffnen und Schließen der Schweißbacken allein durch die Bewegung des beweglichen Teils relativ zum ortsfesten Teil des Linearmotors zu bewirken.Solved is the Task according to the characterizing Part of claim 1. Thereafter, the movable part generates over transverse to the direction of movement of the moving part of a single Linear motor movable coupling element a component of motion transversely to the direction of movement of the moving part to both the lifting and lowering the welding jaws as well as opening and closing the welding jaws solely by the movement of the movable part relative to the stationary part to effect the linear motor.
Die vorgeschlagene Neuerung hat den Vorteil, dass lediglich ein einziger Linearmotor dazu genutzt wird, sowohl das Öffnen und Schließen der Schweißbacken als auch deren Heben und Senken auszuführen. Dabei werden auch nur eine Stromversorgung und eine Kühleinrichtung für die Leiterwindungen des Primärteils benötigt.The proposed innovation has the advantage that only a single Linear motor is used to both open and close the welding jaws as well as their lifting and lowering. It will only be a power supply and a cooling device for the Conductor turns of the primary part needed.
Vorteilhafte Ausgestaltungen der vorgeschlagenen Vorrichtung werden in den Ansprüchen 2 bis 18 beschrieben.advantageous Embodiments of the proposed device are in the claims 2 to 18 described.
Ist gemäß Anspruch 2 das bewegliche Teil in einer vertikalen Bewegungsrichtung entlang eines sich in vertikale Richtung erstreckenden ortsfesten Teils bewegbar, so kann die Leistung des Linearmotors hauptsächlich zum Heben und Senken des gesamten Backenstocks mitsamt Getriebe genutzt werden. Die vergleichsweise geringere Leistung zum Schließen der Schweißbacken kann dann über das Koppelelement erfolgen.is according to claim 2 the moving part in a vertical direction of movement along a vertically extending stationary part movable, so the performance of the linear motor mainly for Lifting and lowering of the entire jaw stock used together with gear become. The comparatively lower power to close the sealing jaws can then over the coupling element take place.
Alternativ dazu kann das bewegliche Teil in einer horizontalen Bewegungsrichtung entlang eines sich in horizontale Richtung erstreckenden ortsfesten Teils bewegt werden (Anspruch 3), wenn diese Bauweise kompakt ist, und die Kräfte zum Heben und Senken des Backenstocks, z. B. wegen relativ leichter Werkstoffe, nicht zu groß sind.alternative to do this, the moving part in a horizontal direction of movement along a horizontally extending stationary part be moved (claim 3), if this construction is compact, and the forces for lifting and lowering the jaw stick, z. B. because of relatively easier Materials that are not too big.
Werden gemäß Anspruch 4 die Schweißbacken mitsamt ihres Getriebes von einer Halterung gehalten, welche entlang einer Führung in vertikaler Richtung verschiebbar ist, so kann die Halterung in einfacher Weise während ihrer Höhenveränderung horizontal ausgerichtet bleiben. Dazu eignen sich in bekannter Weise gerade Führungen (Anspruch 5).Become according to claim 4 the welding jaws held together with their gear from a bracket, which along a guide can be displaced in the vertical direction, so the holder in a simple Way during their height change horizontally stay aligned. These are just in a known manner guides (Claim 5).
Eine vorgegebene Backenbewegung wird erreicht, wenn gemäß Anspruch 6 die Backenauslenkung mittels eines Koppelelementes erfolgt, das eine Rolle aufweist, die entlang einer Kurvenbahn einer ortsfesten Kurvenscheibe abrollt, wobei ein Federelement für ein Anliegen der Rolle an der Kurvenscheibe sorgt, und die Rolle über ein starres Element mit der Halterung verbunden ist. Derart kann bei einer Vertikalbewegung des Backenstockes ein jeweils für eine bestimmte Höhe geeigneter Backenschließzustand vorgegeben werden. Durch Austausch der Kurvenscheibe gegen eine Kurvenscheibe mit einer anderen Kurvenbahn (Anspruch 8) kann eine andersartige Backenbewegung vorgegeben werden. Wird die Kurvenscheibe mittels einer Verstelleinrichtung horizontal versetzt (Anspruch 9), so kann derart der Backendruck verändert werden. Ein vertikales Versetzen der Kurvenscheibe (Anspruch 10) versetzt den Ort des Backenschließens in vertikaler Richtung.A predetermined jaw movement is achieved if according to claim 6, the jaw deflection is effected by means of a coupling element having a roller which rolls along a curved path of a stationary cam, wherein a spring element ensures contact of the roller on the cam, and the role of a rigid Element is connected to the bracket. In this way, during a vertical movement of the jaw stick, a jaw closing state suitable in each case for a certain height can be specified. By replacing the cam against a cam with another curved path (claim 8), a different type of jaw movement can be specified. If the cam hori by means of an adjustment offset zontal (claim 9), so the jaw pressure can be changed. A vertical displacement of the cam (claim 10) offset the location of the jaw closure in the vertical direction.
Eine leichtgängige Ausführung der Bewegung der Schweißbacken quer zur Bewegungsrichtung des beweglichen Teils des Linearmotors wird erreicht, wenn die Halterung auf einem entlang der Führung geführten Rahmen verschiebbar angeordnet ist, und der Rahmen mit dem beweglichen Teil verbunden ist (Anspruch 7).A smooth execution the movement of the welding jaws transverse to the direction of movement of the movable part of the linear motor is achieved when the bracket on a guided along the guide frame slidably disposed, and the frame with the movable Part is connected (claim 7).
Es kann ein Koppelelement eine Bewegungskomponente des Backenstocks erzeugen, die parallel zur Bewegungsrichtung des beweglichen Teils ist, wenn das Koppelelement entsprechende Bauteile aufweist. Gemäß Anspruch 11 ist dazu am beweglichen Teil eine schlitzartige Aufnahme befestigt, in welcher ein an der Halterung befestigter Nocken senkrecht zur Bewegungsrichtung des beweglichen Teils geführt wird. Der Nocken wird zusätzlich entlang einer Kurvenbahn geführt, die sich sowohl in Bewegungsrichtung als auch senkrecht dazu erstreckt, um die Halterung entlang der Kurvenbahn zu bewegen. Derart können beliebige Kurvenbahnen für sinnvolle Backenbewegungen vorgesehen werden.It a coupling element can be a movement component of the jaw stock generate, parallel to the direction of movement of the moving part is when the coupling element has corresponding components. According to claim 11 is attached to the moving part a slot-like recording, in which a mounted on the bracket cam perpendicular to Movement direction of the movable part is guided. The cam is also along a curved path, which extends both in the direction of movement and perpendicular thereto, to move the bracket along the curved path. Such can be any Curved tracks for meaningful Baking movements are provided.
Hohe Maschinenleistungen können bei einem Backenumlauf erreicht werden. Dieser ist möglich, wenn als Koppelelement am beweglichen Teil eine schlitzartige Aufnahme vorgesehen ist, in welcher ein an der Halterung befestigter Nocken senkrecht zur Bewegungsrichtung des beweglichen Teils geführt wird, und der Nocken zusätzlich entlang einer geschlossenen Kurvenbahn geführt wird, um die Halterung in umlaufender Weise zu bewegen (Anspruch 12).Height Machine services can be achieved with a baking cycle. This is possible if as a coupling element on the movable part a slot-like recording is provided, in which a fixed to the bracket cam is guided perpendicular to the direction of movement of the movable part, and the cam in addition is guided along a closed curved path to the bracket to move in a circumferential manner (claim 12).
Es können als Koppelelement am beweglichen Teil aber auch gemäß Anspruch 13 zwei Aufnahmen vorgesehen werden, in denen jeweils ein Nocken geführt wird, wobei jeder Nocken mit jeweils einer Schweißbacke verbunden ist, und zudem jeweils ein Nocken zusätzlich entlang einer eigenen, geschlossenen Kurvenbahn geführt wird. Derart kann entweder ein Backenstock besser geführt werden, oder die beiden Kurvenbahnen bilden das Getriebe zum Erzeugen der gegenläufigen Backenbewegung. Im zweiten Fall kann ein zusätzliches Backengetriebe, z. B. ein Kniehebelmechanismus entfallen.It can as a coupling element on the movable part but also according to claim 13 two shots are provided, in each of which a cam guided is, each cam connected to a respective welding jaw is, and also in each case a cam in addition along its own, closed Curved track led becomes. In this way, either a baking stick can be better guided, or the two curved paths form the transmission for generating the opposing Back movement. In the second case, an additional back gear, z. B. eliminates a toggle mechanism.
Für relativ lange Linearbewegungen ist es sinnvoll, das ortsfeste Teil als Sekundärteil und das bewegliche Teil als Primärteil auszuführen (Anspruch 14). Ein langes Sekundärteil, welches die sich bei Betrieb erwärmenden Magnete aufweist, bleibt auch bei Einsatz unterschiedlicher Metalle für Sekundärteil und Halterung gerade, wenn es aus einer Reihe von Sekundärteilsegmenten gebildet wird, wobei jedes Sekundärteilsegment über eine separate Befestigung mit einer Halterung des Sekundärteils verbunden ist (Anspruch 15).For relative Long linear movements, it makes sense, the stationary part as a secondary part and the moving part as a primary part perform (Claim 14). A long abutment, which warming up during operation Magnets remains even when using different metals for secondary part and Bracket straight when it comes from a set of abutment segments is formed, each secondary segment via a separate attachment connected to a holder of the secondary part is (claim 15).
Eine Bauweise, bei welcher das bewegliche Teil als Sekundärteil und das ortsfeste Teil als Primärteil ausgeführt ist (Anspruch 16), eignet sich für Einsatzfälle, bei denen die Versorgungsleitungen für das Primärteil ortsfest sein sollen.A Construction, in which the movable part as a secondary part and the stationary part as a primary part accomplished is (claim 16), is suitable for Applications, in which the supply lines for the primary part should be stationary.
Das bewegliche Teil kann mittels am ortsfesten Teil vorgesehener Schienen (Anspruch 17) entlang des ortsfesten Teils geführt werden (Anspruch 17).The movable part can be provided by means provided on the stationary part rails (Claim 17) are guided along the stationary part (claim 17).
Die vorgeschlagene Vorrichtung ist insbesondere für vertikale Schlauchbeutelmaschinen (Anspruch 18) geeignet.The proposed device is particularly for vertical tubular bag machines (Claim 18) suitable.
