Description
Verpackungsmaschine, insbesondere zur Herstellung von flachbeutelähnlichen Packungen Zur Herstellung von Flachbeutelpackungen aus heißsiegelfähigen Materialien werden häufig Schließwalzen verwendet, die entsprechende Aussparungen für das Füllgut besitzen und zwischen welchen die Materialbahn beim Durchlaufen verschweißt wird. Packaging machine, in particular for the production of flat pouches Packs For the production of flat pouch packs from heat-sealable materials Closing rollers are often used, the corresponding recesses for the filling material and between which the web of material is welded as it passes through.
Diese Walzen werden normalerweise durch Federdruck gegeneinandergepreßt, wobei der Federdruck regulierbar ist, damit man den Walzendruck der Struktur des Verpackungsmaterials anpassen kann.These rollers are normally pressed against each other by spring pressure, the spring pressure is adjustable so that the roller pressure of the structure of the Can customize packaging material.
Es gibt hier unter anderem auch Maschinen, die in die Walzen eingebaute Schneidmesser haben. Hier wird zum Abschneiden meist ein verhältnismäßig hoher Druck gebraucht. Wo dieser Druck aus Packmaterialgründen nicht für den ganzen Beutelherstellungsvorgang beibehalten werden kann, hat man sich bisher dadurch geholfen, daß die Walzen über genaue Kurvenscheiben gegeneinander so abgestützt waren, daß nur im unmittelbaren Schneidbereich der ganze hohe Federdruck wirken konnte. Derartige Anordnungen sind jedoch in bezug auf die Packmaterialdicke sehr empfindlich. There are also machines here that are built into the rollers Have cutting knives. Here, a relatively high pressure is usually required for cutting second hand. Where this pressure is not applied to the entire bag manufacturing process for reasons of packaging material can be maintained, one has so far helped by having the rollers over exact cams were supported against each other so that only in the immediate Cutting area the whole high spring pressure could act. Such arrangements are however, very sensitive to the thickness of the packing material.
Außerdem hat man bei dieser Anordnung keine Kontrolle mehr über den wirklich auftretenden Druck, da dieser allein durch den vorgegebenen Walzenspalt und die elastischen Kräfte des Packmaterials zustande kommt, so daß der Packstoff auf die Dicke des Walzenspaltes komprimiert wird. In addition, with this arrangement you no longer have control over the actually occurring pressure, as this is solely due to the specified roller gap and the elastic forces of the packaging material come about, so that the packaging material is compressed to the thickness of the nip.
Bei einer anderen bekanntgewordenen Einrichtung zum Warmverschweißen von Verpackungsfolien wird die aus der Schweißzone kommende Verschlußnaht der Packung zwischen mehrere Paare von hintereinander angeordneten Druckrollen geführt, deren Preßdruck so eingestellt ist, daß er von Paar zu Paar größer wird. Dadurch soll eine bessere Festigkeit und Dichtheit der Verschlußnaht erreicht werden, ohne daß ein nachteilig hoher Schweißdruck angewandt werden muß. Diese bekannte Maßnahme betrifft jedoch nicht den Schließwalzendruck selbst und erfordert daher zusätzlich zu den eigentlichen Schließwalzen noch die Anordnung weiterer Druckwalzenpaare. Ferner sind hier keine Mittel vorgesehen, die den Walzendruck selbsttätig nach einem vorgebbaren Programm auf die gewünschte Größe einstellen. In another known device for hot welding The sealing seam of the pack coming from the welding zone is made of packaging films guided between several pairs of pressure rollers arranged one behind the other, whose Compression pressure is set so that it increases from pair to pair. This is supposed to a better strength and tightness of the sealing seam can be achieved without a disadvantageously high welding pressure must be used. This known measure however, does not concern the closing roller pressure itself and therefore requires additional in addition to the actual closing rollers, there is also the arrangement of further pairs of pressure rollers. Furthermore, no means are provided here that the roller pressure automatically after a Set the programmable program to the required size.
Außer in diesen Fällen wurde bisher bei Verpakkungsmaschinen der genannten Art eine Walzendruckregulierung nicht vorgenommen, insbesondere wurde nicht beachtet, daß der Druck zwischen den Walzenflächen bei gleicher äußerer Kraft auf die Walzen je nach der Länge der jeweiligen Naht unterschiedlich ist. So wird die Kraft beispielsweise bei der Herstellung von zwei Längsrändern von je 5 mm Breite auf 10 mm verteilt, während zu einem anderen Zeitpunkt, wenn ein Querverschlußrand von 50 mm Länge zwischen den Längsnähten hergestellt wird, diese Kraft auf insgesamt 60 mm verteilt werden muß, was einen Heißsiegeldruck der Walzen von einem Sechstel des erstgenannten Wertes ergibt. Except in these cases, the mentioned type a roller pressure regulation was not made, in particular does not take into account that the pressure between the roller surfaces with the same external force on the rollers is different depending on the length of each seam. So will the force, for example, when producing two longitudinal edges, each 5 mm wide distributed over 10 mm, while at another point in time, if a cross-locking edge of 50 mm in length is produced between the longitudinal seams, this force to a total 60 mm must be distributed, which is a heat sealing pressure of the rollers of one sixth of the first-mentioned value results.
Von diesen Überlegungen ausgehend, macht die Erfindung den Vorschlag, Verpackungsmaschinen, bei welchen das Packungsmaterial zwischen Schließwalzen hindurchgeführt wird, welche die entsprechenden Siegelnähte herstellen, mit einer Regeleinrichtung zu versehen, welche auf den zum Längs- und Querverschließen der Packungen dienenden Schließwalzendruck einwirkt und die auf ein periodisch zum Arbeitsablauf der Maschine und/oder auf durch Einflüsse außerhalb des periodischen Arbeitsablaufes, vorzugsweise elektrisch vorgebbaren Programms selbsttätig einstellbar ausgebildet ist, wobei die Regeleinrichtung aus elektrischen, hydraulischen oder mechanischen Elementen oder aus einer Kombination dieser Elemente besteht. Based on these considerations, the invention makes the proposal, Packaging machines in which the packaging material is passed between closing rollers which produce the corresponding sealing seams with a control device to be provided, which are used for the longitudinal and transverse sealing of the packs Closing roller pressure acts and which on a periodic to the work flow of the machine and / or due to influences outside the periodic workflow, preferably electrically predeterminable program is designed to be automatically adjustable, wherein the control device made up of electrical, hydraulic or mechanical elements or a combination of these elements.
Das Prinzip, nach dem gesteuert wird, ist ebenfalls variabel. So kann beispielsweise eine konstante Vorspannung entsprechend der für die Längsränder benötigten Kraft auf die Walzen einwirken, während sämtliche größeren erforderlichen Kräfte auf eine der obengenannten Arten aufgebracht werden. Es kann jedoch auch die Spitzenkraft als konstante Kraft aufgebracht werden und die Steuerkraft in entgegengesetzter Richtung wirken. The principle according to which it is controlled is also variable. So For example, a constant preload corresponding to that for the longitudinal edges required force to act on the rollers, while all major required Forces can be applied in one of the ways mentioned above. However, it can also the peak force can be applied as a constant force and the control force in the opposite direction Act direction.
Da es sich bei dem gestellten Programm darum handelt, daß nur die Kraft geändert werden muß, weil der Verarbeitungsdruck nicht geändert wird, ist zunächst keine Verschiebung der Walzen und somit der Druckangriffspunkte zu erwarten. Since the program provided is that only the Force must be changed because the processing pressure is not changed Initially, no shifting of the rollers and thus of the pressure application points is to be expected.
Der Erfindungsvorschlag stellt in erster Näherung eine weglose Kraftregulierung dar. Diese Tatsache läßt es zweckmäßig erscheinen, zur Druckerzeugung einen Elektromagneten heranzuziehen, der nach Art der Konstruktion ziehend oder drückend angewandt werden kann. Besondere Vorteile ergeben sich jedoch, wenn entsprechend einem weiteren Erfindungsvorschlag zur Druckerzeugung ein Elektromagnet mit veränderbarer Zugkraft und zur Druckübertragung auf die Schließwalzen ein mechanisch-hydraulisches System, bestehend aus Druckkolben und Hebeln, verwendet wird. Der Strom würde in diesem Fall durch eine mit der Maschine gekoppelte Steuerung entsprechend der Walzenform vorgeben. As a first approximation, the proposed invention represents a pathless force regulation This fact makes it appear expedient to use an electromagnet to generate pressure to be used, which, depending on the type of construction, can be used pulling or pushing can. However, there are particular advantages if, in accordance with a further inventive proposal an electromagnet with variable tensile force for pressure generation and for pressure transmission a mechanical-hydraulic system consisting of pressure pistons on the closing rollers and levers. In this case the electricity would go through one with the machine Specify coupled control according to the roller shape.
Diese Ausführung ermöglicht erfindungsgemäß noch eine weitere vorteilhafte Anwendung dadurch, daß bei lichtelektrischer Registerregelung der Pakkungsmaterialbahnzufuhr die Druckregeleinrichtung beeinflußbar ausgebildet ist. Dabei kann der Walzendruck auf einen derartig kleinen Wert reduziert werden, daß beispielsweise ein erwünschter Schlupf zwischen Walzen und Packmaterial bzw. vollkommenes Durchrutschen des Packmaterials zwischen den Walzen eintritt. According to the invention, this embodiment enables another advantageous one Application in that with photoelectric register control of the packing material web feed the pressure control device is designed to be influenced. The roller pressure can be used can be reduced to such a small value that, for example, a desirable one Slippage between rollers and packing material or complete slipping of the packing material occurs between the rollers.
Die genannte Kombination eines Elektromagneten mit einer hydraulischen Druckübertragung läßt sich auch bei besonderen konstruktiven Gegebenheiten, z. B. bei einseitiger Mehrfachlagerung der Schließwalzen, vorteilhaft anwenden. Für diesen Fall werden erfindungsgemäß mehrere Druckkolben auf die Schließwalzen zur Einwirkung gebracht, deren Flächen verschieden groß sind. The mentioned combination of an electromagnet with a hydraulic one Pressure transmission can also be used with special structural conditions, e.g. B. in the case of multiple bearings on one side of the closing rollers, use it advantageously. For this In the case of the invention, several pressure pistons act on the closing rollers brought whose areas are of different sizes.
Außerdem bietet das Elektro- und Hydrauliksystem durch seine leichte Programmierbarkeit und Veränderlichkeit des Programms besonders gut die Möglichkeit, an schwachen Stellen der Verschweißung durch etwas mehr Druckgabe diesen Stellen nachzuhelfen bzw. das Druckverhältnis »Längsnaht zu Quernaht« zu verändern oder dann auch noch bei verschiedenen Packmaterialien den ganzen Druckbereich proportional zu verschieben. In addition, thanks to its light weight, the electrical and hydraulic system Programmability and changeability of the program particularly good the possibility of at weak points of the weld by applying a little more pressure to these points to help or to change the pressure ratio "longitudinal seam to transverse seam" or then also with different packaging materials proportionally the entire printing area to move.
Durch das weglose Regeln läßt sich ferner, besonders bei einem verhältnismäßig starren Aufbau des hydraulischen Leitungssystems, in verschiedenen Abständen, d. h. bei verschiedenen Walzendurchmessern, arbeiten, falls ein hydraulischer Rücklauf derart vorgesehen wird, daß im unbelasteten Zustand stets das hydraulische Mittel derartig zu- und abfließen kann, daß die hydraulischen Druckgeber in jeder Lage gehalten werden können und bei Anziehen des Magneten nach Verschluß des Rücklaufs der Aufbau des Anpreßdrucks von der jeweiligen Stellung der hydraulischen Druckgeber aus erfolgen kann. Andererseits läßt sich jedoch auch durch Anwendung mechanischer Zwischenglieder erreichen, daß die Druckgeber stets im gleichen Wegbereich arbeiten. Through the pathless rules one can furthermore, especially with one relative rigid structure of the hydraulic pipe system, at different distances, d. H. at different roller diameters, if there is a hydraulic return it is provided in such a way that the hydraulic means are always used in the unloaded state can flow in and out in such a way that the hydraulic pressure transmitter in any position can be held and when the magnet is pulled after the return is closed the build-up of the contact pressure from the respective position of the hydraulic pressure transducer can be made from. On the other hand, however, can also be done by using mechanical Intermediate links achieve that the pressure transducers always work in the same travel range.
Die Zeichnung zeigt schematisch zwei Anordnungsbeispiele der Erfindung. The drawing shows schematically two arrangement examples of the invention.
Die Schließwalzen 1, 2 sind mit den Siegelflächen 3 für den Querverschluß und den Flächen 4 für den Längsverschluß der Flachbeutel versehen. Die Lager 5 der Walze 1 sind gegen die Walze 2 verschiebbar ausgebildet, während letztere in ortsfesten Lagern 6 gelagert ist. The closing rollers 1, 2 are with the sealing surfaces 3 for the transverse closure and the surfaces 4 are provided for the longitudinal closure of the flat bags. The camp 5 of the Roller 1 are designed to be displaceable against roller 2, while the latter is stationary Storage 6 is stored.
Zum Andrücken der Walze 1 können ihre Lager 5 durch hydraulisch betätigte Kolben 8,9 in den Zylindern 10, 11 mit Druck belastet werden. Zu diesem Zweck sind die Zylinder über die Leitung 12 an eine gemeinsame Druckquelle angeschlossen, bestehend aus dem Kolben 13 im Zylinder 14. Der Kolben 13 ist über den Hebel 15 mit dem Magnetkern 16 einer Solenoidspule verbunden, welche über die Leitungen 18 mit Strom gespeist wird, wobei in den Stromkreis ein Regelwiderstand 19 gelegt ist. To press the roller 1, their bearings 5 can be hydraulically operated Pistons 8, 9 in the cylinders 10, 11 are loaded with pressure. To this end are the cylinder via line 12 to a common pressure source connected, consisting from the piston 13 in the cylinder 14. The piston 13 is connected to the magnetic core via the lever 15 16 connected to a solenoid coil, which is fed via the lines 18 with current is, a variable resistor 19 is placed in the circuit.
Zur selbsttätigen Einstellung des geeigneten Walzenschließdruckes ist das Regelorgan des Widerstandes 19 dem Einfluß des periodischen Arbeitsablaufes der Maschine unterworfen, so daß der jeweils zweckmäßige Anpreßdruck der Walzen durch das Solenoid 16, 17 erzeugt und über die hydraulischen Mittel8 bis 14 auf die Walze 1, praktisch ohne Verzögerung, übertragen wird. Diese Regelung in Abhängigkeit von programmierten, mit dem Arbeitsablauf der Maschine unmittelbar zusammenhängenden Einflußgrößen läßt sich grundsätzlich auch noch auf andere, außerhalb der unmittelbaren Arbeitsweise der Maschine liegende Einflüsse beziehen. Es kann z. B. die im Zusammenhang mit der Bewegung der Materialbahn lichtgesteuerte Registerregelung zur Beeinflussung der Druckregelung benutzt werden. For the automatic setting of the suitable roller clamping pressure is the regulating organ of the resistance 19 to the influence of the periodic work flow subjected to the machine, so that the respective appropriate contact pressure of the rollers generated by the solenoid 16, 17 and via the hydraulic means 8-14 the roller 1 is transferred practically without delay. This scheme is dependent of programmed ones that are directly related to the work flow of the machine In principle, influencing variables can also be applied to others outside of the immediate How the machine works, refer to lying influences. It can e.g. B. the related light-controlled register regulation for influencing the movement of the material web the pressure control can be used.
Das Anordnungsbeispiel nach Fig. 2 betrifft eine andere konstruktive Gegebenheit, bei welcher die Walzen 1, 2 nur einseitig in den querbeweglichen Lagern 20, 21 bzw. in den festen Lagern 22, 23 gelagert sind. Dabei ist das Lager 20 durch den Kolben 24 im Zylinder 25 und das Lager 21 durch den Kolben 26 im Zylinder 27 über den Hebel 28 belastbar. The arrangement example according to FIG. 2 relates to a different constructive one Condition in which the rollers 1, 2 only on one side in the transversely movable bearings 20, 21 or in the fixed bearings 22, 23 are stored. The bearing 20 is through the piston 24 in the cylinder 25 and the bearing 21 through the piston 26 in the cylinder 27 loadable via the lever 28.
Über eine Leitung 12 sind die beiden Zylinder 25. 26 an eine gemeinsame Druckquelle angeschlossen, deren Wirkung, wie in Fig. 1 gezeigt, über die Mittel 15 bis 19 geregelt wird.The two cylinders 25, 26 are connected to a common one via a line 12 Pressure source connected, the effect of which, as shown in Fig. 1, via the means 15 to 19 is regulated.
Entsprechend den Abständen a und b der Lagermitten von der Wirkungslinie der DruckkraftP und der dadurch gegebenen Momentenverteilung kann durch verschieden große Bemessung der hydraulischen Kolben 24, 26 (bzw. bei mechanischen Mitteln durch entsprechend verschiedene Hebellängen) eine gleichmäßige Druckwirkung über die ganze Arbeitsfläche der Walzen erzielt werden. Diese Wirkung bleibt über den ganzen Arbeitsbereich gleich, da der hydraulische Druck und die Kolbenkraft proportional sind. Corresponding to the distances a and b between the center of the bearing and the line of action the pressure forceP and the resulting distribution of moments can be different large dimensioning of the hydraulic pistons 24, 26 (or in the case of mechanical means by accordingly different lever lengths) an even pressure effect over the whole Working surface of the rollers can be achieved. This effect persists over the entire work area equal because the hydraulic pressure and piston force are proportional.
