"Getriebe für eine Vorrichtung zum Querschweißen von mit gleichförmiger Geschwindigkeit bewegten Folienbahnen oder Folienschläuchen11 "Gear for a device for the transverse welding of film webs or film tubes moving at a uniform speed 11
Die Erfindung betrifft ein Getriebe für eine Vorrichtung zum Querschweißen oder Quersiegeln von mit gleichförmiger Geschwindigkeit bewegten endlosen Folienbahnen oder Folienschläuchen, bei der die Schweißwerkzeuge in einer geschlossenen Bahn umlaufen und zeitweise die Folienbahn begleiten.The invention relates to a transmission for a device for Cross-welding or cross-sealing of endless film webs or film tubes moving at a constant speed, in which the welding tools circulate in a closed path and at times accompany the film web.
^uerschweißvorrichtungen, die ausser an sich bekannten Schweißwerkzeugen auch Werkzeuge zum Durchtrennen des" Folienschlauchs aufweisen können, sind meist Bestandteil von kontinuierlich arbeitenden Einwickel- oder Schlauchbeutelmaschinen. Da je Umlauf bzw. Arbeitsspiel der Schweißwerkzeuge wählbare Längen des Folienschlauchs durch die Querschweißvorrichtung gefördert werden, muß die umlauf geschwindigkeit der Schweißwerkzeuge des-* halb gegebenenfalls periodische Ungleichförmigkeiten aufweisen, derart, daß beim Angreifen der Schweißwerkzeuge am Folienschlauch keine unzulässig großen Relativbewegungen entstehen können.^ uerschweißvorrichtungen, the except per se known welding tools can also have tools for cutting through the "film tube, are usually part of continuous working wrapping or tubular bag machines. Because lengths can be selected for each cycle or work cycle of the welding tools of the film tube are conveyed through the transverse sealing device, the rotational speed of the sealing tools must be half possibly have periodic irregularities, such that when the welding tools attack the film tube no inadmissibly large relative movements can arise.

Ss ist deshalb erforderlich, zwischen dem Hauptantrieb der Maschine und der Querschweißvorrichtung ein solche Ungleichförmigkeiten bewirkendes Getriebe einzuschalten.It is therefore necessary to have such irregularities between the main drive of the machine and the transverse welding device to switch on the effecting gear.
Kin bekanntes Getriebe zur Erzeugung periodischer Ungleichförmigkeit besteht im wesentlichen aus zwei einander nachgeordnet en Paaren von Ellipsenzahnrädern. Zum Verstellen sind mindestens drei Ellipsenräder in wählbaren Stellungen auf den sie tragenden Getriebewellen festklemmbar angeordnet. Beim Verstellen des Ungleiohförmigkeitsgrades, das nur bei Stillstand des Getriebes vorgenommen werden kann, müssen das zweite und das dritte auf einer gemeinsamen Welle angeordnete Ellipsenrad gegeneinander verstellt werden. Ausserdem müssen aber auch zur Beibehaltung der Phasenlage der üngleichförmigkeit das erste und vierte Ellipsenrad relativ zu den sie tragenden Wellen verstellt werden. Dieses Verstellen während des Stillstands ist zeltraubend und muß nach kurzen Probeläufen der Maschine gegebenenfalls mehrmals verbessert werden.Kin known gear for generating periodic irregularities consists essentially of two pairs of elliptical gears arranged one after the other. To adjust are at least three elliptical gears can be clamped in selectable positions on the transmission shafts that carry them. At the Adjusting the degree of irregularity, which can only be carried out when the transmission is at a standstill, must be the second and the third elliptical gear arranged on a common shaft can be adjusted against each other. In addition, to maintain the phase position of the non-uniformity, the first and fourth elliptical wheel can be adjusted relative to the shafts carrying them. This adjustment is during the standstill Tenting and may have to be done after brief test runs of the machine to be improved several times.
Es wurde auch schon vorgeschlagen, Differentialgetriebe vorzusehen, mittels denen das zweite Ellipsenrad relativ zum dritten und das erste und da§ vierte Ellipsenrad relativ zur Getriebeeingangs- bzw.-Ausgangswelle verstellt werden können. Da jedochIt has also been proposed to provide differential gears, by means of which the second elliptical gear relative to the third and the first and fourth elliptical gear relative to the transmission input or output shaft can be adjusted. However, since

das Ungleichförmigkeitsgetriebe spielfrei arbeiten soll, wire 'für die Differentialgetriebe ein untragbar hoher Herstellungsaufwand notwendig. Ausserdem wäre aueh mittels der Differentialgetriebe das Einstellen für technisch ungeschultes Personal schwierig, so daß man gezwungen wäre, die Verstellmittel für die Differentialgetriebe miteinander zu kuppeln, was weitere χ Kosten verursachen würde.the irregularity gear should work without backlash, wire 'An unacceptably high manufacturing cost is necessary for the differential gear. In addition, it would also be by means of the differential gear the adjustment for technically untrained personnel difficult, so that one would be forced to use the adjustment means for to couple the differential gears together, what further χ Would incur costs.
Zur Vermeidung der genannten Nachtelle wird erfindungsgemäß vorgesehlagen, in den Antrieb der Querschweißvorrichtung IIn order to avoid the disadvantage mentioned, according to the invention proposed, in the drive of the transverse welding device I
wenigstens ein Kardangelenk einzuschalten, dessen Auslenkwinkel verstellbar ist.to switch on at least one universal joint, its deflection angle is adjustable.
Bei einem bevorzugten Ausführungsbeispiel eines derartigen Getriebes sind vier hintereinander angeordnete, durch drei Zwischenwellen verbundene Kardangelenke vorgesehen, deren Gelenkachsen aufeinanderfolgend um Jeweils 90° gegeneinander versetzt sind, und es ist die mittlere dieser drei Zwischenwellen quer zu der gestreckten Mittelachse der vier Kardangelenke verstell- g bar eingerichtet.In a preferred embodiment of such a transmission of four arranged one behind another, connected by three intermediate shafts universal joints are provided, the joint axes are successively offset from one another by 90 °, and it is the average of these three intermediate shafts adjustable transversely to the elongated central axis of the four universal joints g bar set up.
Dadurch, daß bei diesem Getriebe die Achsender Gelenke abwechselnd um 90° gegeneinander versetzt sind, also nicht wie bei üblichen Kardantrieben jeweils paarweise parallel zueinanderThe fact that in this transmission the axes of the joints alternate are offset from one another by 90 °, i.e. not parallel to one another in pairs as is the case with conventional card drives

liegen, wird die periodische üngleichförmigkeit der Drehbewegung vervielfacht und kann durch die mit der Querverstellung der mittleren Zwischenwelle verbundenen Auslenkung der Gelenke beliebig eingestellt werden.will be the periodic irregularity of the rotary motion multiplied and can be caused by the deflection of the joints associated with the transverse adjustment of the central intermediate shaft can be set as required.
Dieses neuartige Getriebe ist während des Betriebs einstellbar, wobei sich die Phasenlage der üngleichförmigkeit nicht verändert. Das Getriebe kann deshalb auch von technisch ungeschultern Personal leicht eingestellt werden. Ausserdem ist es sehr preiswert, weil Kardangelenke serienmäßig in großen Stückzahlen hergestellt werden. Das Getriebe ist ausser für waagerecht und kontinuierlich arbeitende Schlauchbeutel- und Einwickelmaschinen auch für senkrecht arbeitende Schlauchbeutelherstell-, Füll- und Schließaaschinen wie auch für einfache Beutelherstellmaschinen und allgemein da geeignet, wo Werkzeuge Verpackungen oder deren Bestandteile auf einem Wegstück begleiten, um danach in eine Ausgangslage zurückzukehren.This new type of gear can be adjusted during operation, whereby the phase position of the irregularity does not change changes. The transmission can therefore be easily adjusted even by technically untrained personnel. Besides, it is very inexpensive because universal joints are mass-produced in large numbers. The transmission is except for horizontal and continuously working tubular bag and wrapping machines also for vertical tubular bag manufacturers, Filling and closing machines as well as for simple bag making machines and generally suitable wherever tools Accompany packaging or its components on a part of the journey, in order to then return to a starting position.
Eine zweckmäßige Weiterbildung des erfindungsgemäßen Getriebes ist dadurch gekennzeichnet, daß dem aus den Kardangelenken gebildeten Getriebe zur Erzeugung einer einstellbaren periodischen Ungleichförmigkeit ein Rädergetriebe zur Übersetzung auf höhere Drehzahl und diesem Rädergetriebe wiederum ein weiteres einstellbares Getriebe der erfindungsgemäßen Art nachgeordnet ist, mitAn expedient development of the transmission according to the invention is characterized in that the one formed from the cardan joints Gear to generate an adjustable periodic irregularity, a gear train to translate to higher Speed and this gear train in turn a further adjustable gear of the type according to the invention is arranged downstream with

dem noch eine weitere Variierung der Ungleichförmigkeit des Antriebs der Schweißeinrichtung erzielbar ist.another variation of the irregularity of the Drive the welding device can be achieved.
Durch die Hintereinanderschaltung der beiden einstellbare Ungleichförmigkeiten erzeugenden Getriebe 1st es möglich, die Querschweißvorrichtung derart anzutreiben, daß deren Sehweißwerkzeuge während eines verhältnismäßig langen Teilstücks ihres Umlaufwegs eine nahezu konstante Geschwindigkeit wähl-By connecting the two in series, adjustable It is possible to drive the transverse welding device in such a way that its welding tools select an almost constant speed during a relatively long section of its circular path.

als die ersten HSIften. Infolge der genannten Ausrichtung der Qelenkachsen I9 vervielfachen sich die Ungleichförmigkeiten bis zur zweiten Hälfte 24 des Kardangelenks 10. Es tritt also bei dem erfindungsgeraäßen Getriebe die gegenteilige Wirkung dessen ein, was normalerweise durch paarweises Anordnen von Kardangelenken bewirkt wird, deren an einer Zwischenwelle angreifende Gelenkachsen parallel ausgerichtet sind.than the first HSIths. As a result of the aforementioned alignment of the Articulated axes 19 multiply the irregularities up to the second half 24 of the cardan joint 10. The opposite effect occurs in the transmission according to the invention one of what is normally effected by arranging universal joints in pairs, those engaging an intermediate shaft Joint axes are aligned parallel.
An das Kardangelenk 10 könnte die Querschweißvorrichtung 1 direkt angeschlossen sein. Da es jedoch für die Lebensdauer der Querschweißvorrichtung 1 vorteilhaft ist, wenn während eines Umlaufs nur einmal Beschleunigung und Verzögerung auftritt, ist zwischen dieser und dem Getriebe 3 zur Erzeugung periodischer Ungleichförmigkeit ein Rädergetriebe 31 eingebaut, derart, daß je Umlauf der Schweißwerkzeuge der Querschweißvorrichtung 1 die Kardangelenke 7, 8, 9, 10 nur einen halben Umlauf ausführen.The transverse welding device 1 could be attached to the universal joint 10 be connected directly. However, since it is advantageous for the life of the transverse welding device 1 if during a Acceleration and deceleration occurs only once per revolution, is periodic between this and the transmission 3 to generate Irregularity installed a gear train 31, such that per revolution of the welding tools of the transverse welding device 1, the cardan joints 7, 8, 9, 10 only perform half a revolution.
Wenn die Querschweißvorrichtung 1 in einer Einwickelmaschine verwendet wird und deshalb in Bezug auf den Folienschlauch 4 höhenverstellbar sein soll, so wird zwischen dem Getriebe Jl und der Querschweißvorrichtung 1 eine Kardanwelle 32 eingebaut, deren Gelenke 33 in der allgemein üblichen Weise so ausgerichtet sind, daß bei einer Auslenkung derselben keine zusätzliche Ungleichförmigkeit erzeugt wird.When the transverse sealing device 1 is used in a wrapping machine and therefore in relation to the film tube 4 should be adjustable in height, so is between the gear Jl and the transverse welding device 1 installed a cardan shaft 32, the joints 33 of which are aligned in the generally customary manner so that when they are deflected, no additional Nonuniformity is generated.

Das Rädergetriebe 51 kann mit einer an sieh bekannten Kupplung 35 versehen sein, derart, daß die Phasenlage der Schweißwerkzeuge zu den Kardangelenken 7, 8* 9, 10 einstellbar ist. Dadurch kann aus dem Verlauf der erzeugten Ungleiohförmigkeit ein Teilstück derart ausgewählt werden, daß, bei Verwendung innerhalb einer Einwickelmaschine oder Schlauehbeutelhersteil-, Füll- und Schließmaschine auch bei dem unmittelbar vor dem Querschweißen erfolgenden Flachfalten des Folienschlauchs 4 eine zu diesem unzulässige Relativbewegung der Schwelßwerkzeuge vermieden wird. Dem gleichen Zweck könnte gegebenenfalls auch eine von der vorstehend beschriebenen Ausrichtung abweichende Anordnung der Gelenkachsen 19 der einzelnen Kardangelenke "J3 8, 9, 10 dienen.The gear train 51 can be provided with a clutch 35 known per se, in such a way that the phase position of the welding tools with respect to the universal joints 7, 8 * 9, 10 is adjustable. As a result, a section can be selected from the course of the irregularity produced in such a way that, when used within a wrapping machine or a tubular bag making, filling and closing machine, even when the tubular film 4 is folded flat immediately before the transverse welding, an impermissible relative movement of the welding tools is avoided . An arrangement of the joint axes 19 of the individual universal joints ″ J 3 8, 9, 10 that deviates from the alignment described above could serve the same purpose.
Das Ausführungsbeispiel gemäß Fig. 2 unterscheidet sieh von demjenigen nach Fig. 1 dadurch, daß dem Rädergetriebe 31 ein zweites Getriebe J>6 zur Erzeugung einer einstellbaren periodischen Ungleichförmigkeit nachgeordnet ist, welches du'rch ein Lager 37 hindurch seinerseits über eine weitere Kupplung 38 die Querschweiß vorrichtung 1 mittel- oder unmittelbar antreibt. Das zweite Getriebe 36 kann wie das erste aufgebaut und mit vier nicht dargestellten Kardangelenken versehen sein und ebenfalls mittels einer Handkurbel 34 verstellt werden. Die Kupplung 38 dient zum Ausrichten der Kardangelenke des zweiten Getriebes 36 relativ zu den Schweißwerkzeugen.The embodiment according to FIG. 2 differs from that according to FIG. 1 in that a second transmission J> 6 is arranged downstream of the gear train 31 for generating an adjustable periodic irregularity, which by means of a bearing 37 in turn via a further clutch 38 Cross welding device 1 drives directly or indirectly. The second gear 36 can be constructed like the first and provided with four universal joints (not shown) and can also be adjusted by means of a hand crank 34. The coupling 38 serves to align the universal joints of the second gear 36 relative to the welding tools.

Mittels der Kupplung 35 können die Kardangelenke des zweiten Getriebes 36 zu denen des ersten ausgerichtet werden. Mit Hilfe des zweiten Getriebes J56 erzeugbare Ungleichförmigkeiten können in wählbarer Weise zum abwechselnden Vergrössern und Verkleinern von mittels des ersten Getriebes 3 erzeugten Ungleichförmigkeiten dienen. Bei geeigneter Einstellung der Kupplung 35 und der beiden Getriebe 3 und 36 entsteht ausgangs des zweiten Getriebes 36 beispielsweise eine Drehbewegung, welche während eines verhältnismäßig großen Teils der für einen Umlauf benötigten Zeitdauer eine im wesentlichen konstante Umlaufgeschwindigkeit aufweist, die in einem gewünschten Verhältnis zur Durchschnittsumlauf geschwindigkeit steht. Dadurch können die Schweißwerkzeuge während eines verhältnismäßig langen Teilstücks eines Umlaufs an dem Folienschlauch 4 angreifen, was, wie bereits eingangs erwähnt, eine Leistungssteigerung ergibt.By means of the coupling 35, the universal joints of the second gear 36 can be aligned with those of the first. With help The irregularities that can be generated by the second gear J56 can be selected in a selectable manner for alternating enlargement and reduction of irregularities generated by means of the first gear 3 are used. With a suitable setting of the clutch 35 and the two transmissions 3 and 36 arise from the output of the second Transmission 36, for example, a rotary movement which during a relatively large part of the required for one revolution Period of time has a substantially constant speed of revolution, which is in a desired ratio to the average revolution speed stands. This allows the welding tools during a relatively long section of a Attack around the film tube 4, which, as already mentioned, results in an increase in performance.
