Abstract

A packaging foil is continuously withdrawn from a supply. The foil is folded around the products to be packaged. Cut-off lengths of closing profile sections are inserted with a feed unit between the two longitudinal edges of the foil. In a sealing station, the two longitudinal edges of the foil are sealed together and the foil is then sealed onto the closing profile sections. In another sealing station, transverse sealing seams are formed between the free ends of successive closing profile sections and the tube is cut approximately in the center of the transverse seams. A high packaging output is achieved as a result of the continuous withdrawal of the foil.

Das Verschlussprofil 13 wird durch eine zweite Vorschubeinheit 37 vom Vorrat 12 abgezogen. Die Einheit 37 umfasst ein Transportrollenpaar 38, das von einem Servomotor 39 mit Winkelfühler 40 angetrieben ist, die ebenfalls mit der Steuereinrichtung 32 verbunden sind. Die Rollen 38 haben eine Umfangsnut 41 entsprechend der Nut 30. Stromabwärts der Rollen 38 ist eine Trenneinrichtung 42 zum Trennen des Verschlussprofils 13 in Verschlussprofilstücke 43 einstellbarer Länge angeordnet. Die Einrichtung 42 besteht aus einem umlaufenden Messer 44, dass durch einen weiteren Servomotor 45 mit Winkelfühler 46 angetrieben ist. Diese sind ebenfalls mit der Einrichtung 32 verbunden. Das Messer 44 arbeitet mit einem umlaufenden oder stationären Gegenhalter 47 zusammen.The closure profile 13 is by a second feed unit 37 deducted from stock 12. The unit 37 comprises a pair of transport rollers 38 by a servo motor 39 with an angle sensor 40 is driven, which also with the control device 32nd are connected. The rollers 38 have a circumferential groove 41 accordingly groove 30. Downstream of rollers 38 is a separator 42 for separating the closure profile 13 into closure profile pieces 43 adjustable length arranged. The facility 42 consists of a rotating knife 44 that by a another servo motor 45 is driven with an angle sensor 46. This are also connected to the device 32. The knife 44 works with a rotating or stationary counterholder 47 together.

Die Profilstücke 43 werden von der Einheit 37 zwischen die beiden Folien beabstandet von aber benachbart den Kanten 29 zugeführt. Zwischen den beiden Rollenpaaren 18, 19 bzw. 20, 21 sind zwei Längs-Siegelstationen 50, 51, zur Bildung einer Längssiegelnaht 49 und zum beidseitigen Aufsiegeln der Folie 11 auf die Profilstücke 43 angeordnet. Die Stationen 50, 51 bestehen aus je einem Paar von kontinuierlich zumindest beinahe aneinanderliegenden, beheizten Siegelbacken 52, 53. Diese können auf der der Folie 11 zugewandten Seite mit PTFE beschichtet sein. Die Folie 11 wird durch das Rollenpaar 20, 21 kontinuierlich zwischen den Backen 50, 51 durchgezogen. Die Rollen 20, 21 können gekühlt sein. Sie sorgen dann für ein rasches Abkühlen der Siegelnähte.The profile pieces 43 are from the unit 37 between the two Foils spaced from but adjacent edges 29 fed. Between the two pairs of rollers 18, 19 and 20, 21 are two longitudinal sealing stations 50, 51, to form a longitudinal sealing seam 49 and for sealing the film 11 on both sides onto the Profile pieces 43 arranged. The stations 50, 51 consist of each a pair of continuously at least almost contiguous, heated sealing jaws 52, 53. These can on the Film 11 facing side be coated with PTFE. The foil 11 is continuously between the Jaws 50, 51 pulled through. The rollers 20, 21 can be cooled his. They then ensure that the sealed seams cool down quickly.

Stromabwärts des Rollenpaares 20, 21 ist eine Quersiegelstation 56 angeordnet. Sie besteht aus zwei auf ovalen Bahnen 57 umlaufenden Quersiegelbacken 58, 59. In die Backen 58, 59 kann eine Trenneinrichtung bestehend aus einem Messer 60 und einem Gegenhalter 61 integriert sein. Die Art der Führung der Backen 58, 59 ist im Stand der Technik bekannt. Durch dieses Messer wird der Schlauch 16 in Einzelbeutel 66 unterteilt.Downstream of the pair of rollers 20, 21 is a cross sealing station 56 arranged. It consists of two circulating on oval tracks 57 Cross sealing jaws 58, 59. One can be placed in the jaws 58, 59 Separating device consisting of a knife 60 and a counter holder 61 be integrated. The way of guiding the jaws 58, 59 is known in the art. With this knife the Hose 16 divided into individual bags 66.

Bei einer der Rollen 18, 19 kann noch ein Fühler 62 angeordnet werden, der ebenfalls mit der Steuereinrichtung 32 verbunden ist. Der Fühler 62 kann zum Beispiel ein Kraftfühler oder ein Wegfühler sein. Wenn das vorlaufende Ende 63 eines Profilstücks 43 zwischen den Rollen 18b, 19b erfasst wird, werden diese nämlich leicht auseinandergerückt zum Erzeugen der nötigen Anpresskraft der Folie auf das Profilstück 43. Diese erhöhte Anpresskraft oder die dadurch bedingte Verschiebung wird mit dem Fühler 62 erfasst.A sensor 62 can also be arranged on one of the rollers 18, 19 are also connected to the control device 32 is. The sensor 62 can be, for example, a force sensor or a Be path sensors. If the leading end 63 of a profile piece 43 between the rollers 18b, 19b, these are namely slightly moved apart to generate the necessary contact pressure the film on the profile piece 43. This increased contact pressure or the resulting shift is with the feeler 62 recorded.

Im Betrieb arbeitet die beschriebene Vorrichtung wie folgt: Die Folie 11 wird von der Einheit 17 kontinuierlich abgezogen. Die Einheit 37 transportiert das Profil 13 ebenfalls kontinuierlich. Wenn der Fühler 62 anspricht, löst dessen Signal über die Einrichtung 32, verzögert durch einen einstellbaren, mit dem Winkelfühler 31 gemessenen Drehwinkel, eine Drehung des Messers 44 um 360° aus, wobei die Umlaufgeschwindigkeit der Schnittkante der Vorschubgeschwindigkeit des Profils 13 entspricht, die mit der Abzugsgeschwindigkeit der Folie 16 synchronisiert ist. Sobald der Trennschnitt ausgeführt ist, verlangsamt die Einrichtung 32 den Motor 39 kurzfristig und beschleunigt ihn anschliessend wieder auf die Synchron-Geschwindigkeit. Auf diese Weise wird ein Abstand x zwischen dem vorlaufenden Ende 63 des Profilstücks 43 und dem nachlaufenden Ende 64 des vorangegangenen Profilstücks 43 gebildet. Dieser Abstand x entspricht der Breite b der Quersiegelbacken 61 oder ist geringfügig grösser. Die Quersiegelnähte 65 werden nur in dieser Lücke zwischen zwei aufeinanderfolgenden Profilstücken 43 gebildet. Dadurch wird eine einwandfreie Versiegelung und eine gute Dichtheit erzielt. Wegen des kontinuierlichen Abzugs wird eine hohe Verpackungsleistung erzielt. In operation, the device described works as follows: The Slide 11 is continuously withdrawn from unit 17. The Unit 37 also transports the profile 13 continuously. When the sensor 62 responds, its signal triggers via the device 32, delayed by an adjustable, with the angle sensor 31 measured angle of rotation, one rotation of the knife 44 by 360 °, with the rotational speed of the cutting edge the feed rate of the profile 13 corresponds to that with the pull-off speed of the film 16 is synchronized. As soon as the cut is made, slows down the setup 32 the motor 39 briefly and then accelerates it back to the synchronous speed. To this A distance x between the leading end 63 of the Profile piece 43 and the trailing end 64 of the previous one Profile piece 43 formed. This distance x corresponds to the Width b of the transverse sealing jaws 61 or is slightly larger. The transverse sealing seams 65 are only in this gap between two successive profile pieces 43 formed. This will make one perfect sealing and good tightness achieved. Because of the continuous deduction, high packaging performance achieved.

Alternativ zur Auslösung des Messers 44 durch den Fühler 62 kann der Befehl zum Auslösen der Trennbewegung durch das Messer 44 auch ausschliesslich vom Drehwinkel des Rollenpaares 18, 19 abgeleitet werden, der mit dem Fühler 31 gemessen wird. Durch die beschriebene Art der Steuerung wird eine exakte Positionierung der Verschlussprofilstücke 43 zwischen den Quernähten 65 erreicht. Die Einrichtung 37 kann auch zum Nachrüsten bestehender Schlauchbeutel-Verpackungsmaschinen eingesetzt werden. Die Vorrichtung eignet sich vor allem für Horizontal-Schlauchbeutel-Verpackungsmaschinen.As an alternative to triggering the knife 44 by the sensor 62 the command to initiate the separation movement by the knife 44 also derived exclusively from the angle of rotation of the pair of rollers 18, 19 be measured with the sensor 31. Through the described type of control is an exact positioning the closure profile pieces 43 reached between the transverse seams 65. The device 37 can also be used to retrofit existing ones Tubular bag packaging machines are used. The device is particularly suitable for horizontal tubular bag packaging machines.

In Figuren 1 und 2 sind die Rollen 38 und der Vorrat 12 in der vertikalen Mittelebene durch die Siegelbacken 53 angeordnet. Bei der Variante nach Figur 3 ist die vertikale Ebene durch die Rollen 38, das Messer 44 und den Vorrat dagegen unter einem spitzen Winkel zu dieser Mittelebene angeordnet. Die abgeschnittenen Verschlussprofilstücke 43 werden durch eine abgebogene Führungsschiene 70 den Rollen 18b, 19b zugeführt. Diese Variante kann Vorteile bei der Zuführung der Produkte 15 zwischen die gefaltete Folie 11 haben.Figure 3 shows a section of a variant of the embodiment according to FIGS. 1 and 2. In FIGS. 1 and 2, the rollers 38 and the supply 12 in the vertical median plane through the sealing jaws 53 arranged. 3 is the vertical plane through the rollers 38, the knife 44 and the stock in contrast, arranged at an acute angle to this median plane.
