Description

Form-, FiII-, Sealmaschine sowie Verfahren zum Herstellen, Befüllen und Schließen von Säcken Forming, fi ll, sealing machine and method for producing, filling and closing sacks
Die Erfindung betrifft eine Form-, FiII-, Sealmaschine sowie Verfahren zum Herstellen, Befüllen und Schließen von Säcken. Derartige Maschinen sind bekannt und werden in verschiedenen Bereichen der Technik verwendet. An diesen Maschinen wird die Bildung eines Sackes („Form"), dessen Befüllung („Fill") und sein Verschließen („Seal") vorgenommen. In Bezug auf diese Maschinen hat sich daher auch im deutschen Sprachraum die Bezeichnung FFS für Form-, FiII- und Sealmaschine durchgesetzt.The invention relates to a form, FiII-, sealing machine and method for producing, filling and closing of bags. Such machines are known and used in various fields of technology. The formation of a sack ("mold"), its filling ("fill") and its sealing ("seal") are carried out on these machines, which is why the term FFS has also been used in the German-speaking world for forming, FiII- and sealing machine enforced.
Besonders leistungsfähige und automatisierte Varianten dieser Maschinen wickeln einen Kunststoffschlauch von einer Abwickelstation ab, nehmen eine Querschweißung an diesem vor, vereinzeln den mit Querschweißungen versehenen Schlauch zu Säcken (= Schlauchstück mit Querschweißung), öffnen den Sack, befüllen den Sack mit einem Füllrohr mit Füllgut, schließen den Sack, versehen die verschlossene Sacköffnung mit einer weiteren den Sack verschließenden Querschweißung und legen den fertigen und befüllten Sack auf einer geeigneten Palette oder einem Transportmittel wie einem Förderband ab. Oft sind einem jeden oder zumindest einer Mehrzahl der genannten Bearbeitungsschritte eigene Bearbeitungsstationen zugeordnet. In diesem Fall sind geeignete Transportmittel vorzusehen. Betrachtet man bereits die Abwicklung als Bearbeitungsstation, so werden die Transportmittel, mit denen der Schlauch von der Abwicklung zu der Querschweiß- und der Schneidvorrichtung gebracht wird, in der Regel typische Schlauchtransportmittel wie Leitwalzen und Rollen umfassen. Nach der Vereinzelung der Säcke werden ausgefallenere Transportmittel, die in der Regel Greifmittel umfassen, nötig, da die Säcke in der Regel an ihrem noch offenen Ende ergriffen werden und transportiert werden sollen. Hierbei hängt das verschlossene Ende in der Regel herunter. Als Greifmittel finden oft einzelne Greiferzangen oder Greiferzangenpaare Verwendung.Particularly efficient and automated variants of these machines wrap a plastic tube from a unwinding station, make a transverse weld on this, singulate the tube provided with transverse welds to bags (= piece of tube with transverse welding), open the bag, fill the bag with a filling tube with filling material, Close the bag, provide the closed bag opening with another closing the bag closing transverse and place the finished and filled bag on a suitable pallet or a means of transport such as a conveyor belt. Often, each or at least a plurality of said processing steps are associated with their own processing stations. In this case, suitable means of transport should be provided. If one already considers the unwinding as a processing station, then the transport means with which the hose is brought from the unwinding to the transverse welding and the cutting device generally comprise typical hose transport means such as guide rollers and rollers. After Separation of the sacks will require more unusual means of transport, which as a rule comprise gripping means, since the sacks are generally to be grasped at their still open end and transported. In this case, the closed end usually hangs down. As gripping means often find individual gripper tongs or gripper pair use.
Zum Beispiel zeigt die EP 1 201 539 B1 eine solche Maschine. Die Art und Weise, wie in der in dieser Druckschrift dargestellten Maschine Säcke oder Sackhalbzeuge transportiert oder gefertigt werden, die Abfolge der einzelnen Bearbeitungsstationen aufeinander sowie die Art und Weise, in der in dieser Maschine Säcke hergestellt, befüllt und verschlossen werden, ist zum Verständnis der vorliegenden Druckschrift unerlässlich und wird hiermit in den Umfang derselben mit einbezogen. Mit einer solchen Maschine lassen sich Säcke in sehr schneller Abfolge fertigen und befüllen.For example, EP 1 201 539 B1 shows such a machine. The manner in which bags or semi-finished sacks are transported or manufactured in the machine shown in this publication, the sequence of the individual processing stations on each other as well as the manner in which bags are made, filled and sealed in this machine is for the understanding of This document is essential and is hereby included in the scope of the same. With such a machine, bags can be finished and filled in a very quick sequence.
Bei der in der vorgenannten Druckschrift vorgestellten Maschine sind alle Bearbeitungsstationen - zumindest zu dem Zeitpunkt, in dem ihnen ein Sack oder Sackhalbzeug übergeben wird - in der horizontalen Ebene in der Bearbeitungsrichtung der Säcke weitgehend geradlinig zueinander angeordnet. Die horizontale Ebene entspricht dabei in der Regel dem Hallenboden, auf dem die Maschine steht. Eine andere Möglichkeit, diese Ebene funktional zu definieren, wäre bei einer modernen, mit Schlauchabwicklung versehenen Maschine nach der EP 1 201 539 B1 die Ebene, die von der Achse der Abwicklung und der Abzugsrichtung des Schlauches aufgespannt wird. Diese Unterscheidung ist nicht unwichtig, da zuzugestehen ist, dass verschiedene Bearbeitungsstationen nach der vorgenannten Druckschrift, aber auch nach der US 6,401 ,439, in vertikaler Richtung voneinander beabstandet sein können.When presented in the aforementioned document machine all processing stations - at least at the time in which they are handed over a bag or semi-finished bag - arranged in the horizontal plane in the processing direction of the bags largely rectilinear to each other. As a rule, the horizontal level corresponds to the hall floor on which the machine stands. Another possibility to define this level functionally, would be in a modern, provided with hose processing machine according to EP 1 201 539 B1, the plane which is spanned by the axis of the unwinding and withdrawal direction of the hose. This distinction is not unimportant, since it is to be admitted that various processing stations according to the aforementioned publication, but also according to the US 6,401, 439, in the vertical direction may be spaced apart.
Die Reduktion der Wartungs- und Bedienungskosten einer solchen Maschine ist eine beständig fortbestehende Aufgabe der Maschinenkonstrukteure und liegt auch der vorliegenden Erfindung zugrunde. Es hat sich gezeigt, dass die Bedienbarkeit und Wartbarkeit einer solchen Maschine mit geradlinig hintereinander angeordneten Bearbeitungsstationen ausbaufähig ist.The reduction of the maintenance and service costs of such a machine is a persistent task of the machine designers and is also the basis of the present invention. It has been found that the operability and maintainability of such a machine with rectilinearly arranged processing stations is expandable.
Die Aufgabe der vorliegenden Erfindung wird daher dadurch gelöst, dass zumindest eine zweite Gruppe von zumindest einer Bearbeitungsstation in der horizontalen Ebene (x,z) in der Bearbeitungsrichtung der Säcke (z) nicht geradlinig hinter der ersten (geradlinig hintereinander angeordneten) Gruppe angeordnet ist.The object of the present invention is therefore achieved in that at least one second group of at least one processing station in the horizontal plane (x, z) in the processing direction of the bags (z) is not arranged in a straight line behind the first (rectilinearly arranged) group.
In diesem Fall steigt insbesondere die Zugänglichkeit der Bearbeitungsstationen, die dem „Knick" oder den Quertransportmitteln, die die gerade Transportlinie gewissermaßen unterbrechen, unmittelbar benachbart sind. Besonders nützlich ist diese Unterbrechung der geraden Linie dann, wenn hinter der ersten geradlinig angeordneten Gruppe von Bearbeitungsstationen und der Unterbrechung der „geraden Linie" eine zweite Gruppe mit mehr als einer Bearbeitungsstation folgt. Dann steigt die Zugänglichkeit einer Mehrzahl von Bearbeitungsstationen. In dieser zweiten Gruppe kann auch wieder eine gerade Anordnung der Bearbeitungsstationen vorherrschen. Vorteile bestehen, wenn die Unterbrechung durch einen Quertransport, der im Wesentlichen rechtwinklig zum vorausgegangenen geradlinigen Transport stattfindet, vorgenommen wird. Andere Winkel sind jedoch auch denkbar und sie fallen zunächst unter die Definition von Quertransport im Sinne dieser Anmeldung, da eine Änderung der Transportrichtung um beispielsweise 30 ° natürlich auch dazu führt, dass der Quertransport in vektoriellem Sinn Querkomponenten enthält.In this case, in particular, the accessibility of the processing stations, which are immediately adjacent to the "kink" or the transverse transport means which somehow interrupt the straight transport line, is particularly useful when behind the first rectilinear group of processing stations and the interruption of the "straight line" is followed by a second group with more than one processing station. Then the accessibility of a plurality of processing stations increases. In this second group can also prevail again a straight arrangement of processing stations. Advantages exist when the interruption is made by a transverse transport, which takes place substantially perpendicular to the previous rectilinear transport. However, other angles are also conceivable and initially fall under the definition of transverse transport in the sense of this application, since a change in the transport direction by, for example, 30 ° naturally also results in the transverse transport in a vectorial sense containing transverse components.
Gemeint ist mit dem Wort „Quertransport" jedoch der Transport von Säcken oder Sackbestandteilen sowie Sackhalbzeugen (auch diese Begriffe werden in der vorliegenden Anmeldung oft synonym gebraucht und der Begriff Säcke umfasst oft die beiden anderen Begriffe) zwischen den Bearbeitungsstationen, nicht gemeint ist jedoch der Transport ganzer Bearbeitungsstationen. Ein Transport ganzer Bearbeitungsstationen kann naturgemäß auch zum Transport und Quertransport von in der jeweiligen Bearbeitungsstation befindlichen Säcken relativ zum Maschinengestell führen, ist aber nicht gemeint. Aufgrund des Gewichts insbesondere von Abfüllstationen hat sich der Transport derselben nicht bewährt.However, the term "transverse transport" refers to the transport of sacks or sack components as well as semi-finished sacks (these terms are often used interchangeably in the present application and the term sacks often includes the other two terms) between the processing stations, but not transportation Naturally, the transport of entire processing stations can also be used for the transport and cross-transport of machines located in the respective processing station Sacks relative to the machine frame lead, but is not meant. Due to the weight in particular of filling stations, the transport of the same has not been proven.
In der vorliegenden Anmeldung wird von vorwiegend ortsfesten Bearbeitungsstationen ausgegangen und der „Sacktransport" wird als das Verbringen des Sackes von einer zur nächsten Bearbeitungsstation verstanden. Die zumindest eine zweite Gruppe kann auch wieder in einem 90-°-Winkel an den Quertransport angeschlossen sein. Die Wortwahl zumindest einer zweiten Gruppe zeigt natürlich, dass zumindest auch an zwei, drei oder vier solcher zweiter Gruppen gedacht ist, was einen modularen Aufbau der ersten und zweiten Gruppen nahe legt. Eine Mehrzahl von zweiten Gruppen ist vor allem dann vorteilhaft, wenn sie Bearbeitungsstationen enthält, deren Bearbeitungsgeschwindigkeit langsamer ist als die Bearbeitungsgeschwindigkeit der Bearbeitungsstationen der ersten Gruppe. Eine solche deutliche Differenz in der Bearbeitungsgeschwindigkeit kommt beispielsweise beim Abfüllen staubiger Güter zwischen der Befüllstation und den ihr vorgelagerten Stationen zustande, da die staubigen Güter die mögliche Abfüllgeschwindigkeit reduzieren. Beispiele für staubige Güter sind Zement und Titandioxid. Diese Stoffe bilden beim freien Fall vom Füllorgan zum Sackboden derart große Staubmengen, dass die Sauberkeit der Maschinenhalle, die Funktionalität der Maschine und vor allem die Schweißfähigkeit der Folie im Bereich der Sacköffnung in beträchtliche Mitleidenschaft gezogen werden. Auch das Verbleiben von Luft in dem gefüllten und verschlossenen Sack ist ein Problem bei diesen Füllgütern.In the present application, predominantly fixed processing stations are assumed, and the "bag transport" is understood to mean the transfer of the bag from one processing station to the next, and the at least one second group can also be connected to the transverse transport again at a 90 ° angle Of course, the wording of at least one second group shows that at least two, three or four such second groups are intended, which suggests a modular structure of the first and second groups Such a significant difference in the processing speed is, for example, when filling dusty goods between the filling station and the stations upstream of her, as the dusty goods, the possible., The processing speed is slower than the processing speed reduce the filling speed. Examples of dusty goods are cement and titanium dioxide. These substances form in the free fall of the filling member to the sack so large amounts of dust that the cleanliness of the machine hall, the functionality of the machine and especially the weldability of the film in the sack opening are affected significantly. Also, the retention of air in the filled and closed bag is a problem with these contents.
Daher werden verschiedene Maßnahmen zur Reduzierung des Staubes und des Lufteintrags in das Füllgut erwogen, die zum Teil auch in der EP 1 459 981 A1 erwähnt sind:Therefore, various measures for reducing the dust and the air intake into the contents are considered, which are also partially mentioned in EP 1 459 981 A1:
- eine Förderschnecke zum Fördern staubiger Güter in einen Sack,a screw conveyor for conveying dusty goods into a bag,
- Hubmittel zur Veränderung des Relativabstandes zwischen dem Sackboden eines anzufüllenden Sackes und der Auslassöffnung der Fördermittel, - Steuermittel, welche den Abstand zwischen der Auslassöffnung der Fördermittel und dem Füllstand des Sackes während des Füllprozesses steuern,Lifting means for changing the relative distance between the bag bottom of a bag to be filled and the outlet opening of the conveying means, Control means which control the distance between the outlet opening of the conveying means and the filling level of the bag during the filling process,
- Absaugmittel, welche während des und/oder nach dem Füllprozess(es) Luft aus dem Sack saugen,Suction means, which suck air out of the bag during and / or after the filling process (es),
- Rüttelvorrichtungen, welche den Sack während des und/oder nach dem Befüllen(s) rütteln.- Rüttelvorrichtungen which shake the bag during and / or after filling (s).
Zumindest ein Teil dieser Maßnahmen verringert die Abfüllgeschwindigkeit gegenüber einer Vorrichtung, wie sie in der eingangs erwähnten und inkorporierten EP 1 201 539 B1 gezeigt ist, jedoch erheblich.At least part of these measures, however, significantly reduce the filling speed compared to a device as shown in EP 1 201 539 B1 mentioned and incorporated above.
Daher ist es vorteilhaft, insbesondere mehrere Abfüllstationen in einer Maschine vorzusehen. Vor dem Hintergrund der vorliegenden Erfindung könnte daher die Unterbrechung des geradlinigen Transports nach der Querschweißoder Trennstation erfolgen. Nach der Sackbefüllung könnten die von einer Mehrzahl von Abfüllstationen befüllten Säcke wieder gemeinsamen Bearbeitungsstationen zugeführt werden. So könnte das Verschließen und Verschweißen entweder von gemeinsamen Stationen oder von den Abfüllstationen individuell zugeordneten Stationen vorgenommen werden.It is therefore advantageous to provide in particular several filling stations in one machine. Against the background of the present invention, therefore, the interruption of the straight-line transport to the transverse welding or separating station could take place. After bag filling, the bags filled by a plurality of filling stations could be returned to common processing stations. Thus, the closing and welding could be carried out either by common stations or by the filling stations individually assigned stations.
Es hat sich auch herausgestellt, dass in Zusammenhang mit dem Quertransport aus Gründen der Bearbeitungsgeschwindigkeit eine Übergabe- oder Zwischenstation gewinnbringend angeordnet werden kann. Eine solche Station verfügt über Greifmittel und hält den Sack in der Regel während eines Bruchteiles eines Maschinentaktes. Sie kann vor oder nach dem Quertransport angeordnet werden. Auch diese Greifer können Bewegungen in der Sacktransportrichtung ausführen.It has also been found that in connection with the transverse transport for reasons of processing speed, a transfer or intermediate station can be arranged profitably. Such a station has gripping means and usually holds the bag for a fraction of a machine cycle. It can be arranged before or after the transverse transport. These grippers can also perform movements in the bag transport direction.

Die Figuren 1 bis 4 und 7 zeigen Skizzen erfindungsgemäßer Maschinen 2, bei denen die Transportmittel 6, 10, 11 , 12, 21 , 22 und die einzelnen Bearbeitungsstationen 4, 7, 9, 12, 13 lediglich stilisiert dargestellt wurden. Für eine detailliertere Darstellung dieser Gegenstände wird insbesondere auf die bereits mehrfach zitierte und inkorporierte EP 1 201 539 B1 sowie die ebenfalls erwähnten EP 1 459 981 A1 und US 6,401 ,439 verwiesen, die in dieser Beziehung akribischere Beschreibungen und Figuren aufweisen. Dieser Hinweis gilt insbesondere auch in Bezug auf die Greiferzangen und Greiferzangenpaare 10, 11 sowie über die Art und Richtung (vor allem z), in der sie 10, 1 1 die Säcke 1 durch die Maschine 2 transportieren. Auch die diesbezüglichen Passagen der EP 1 201 539 B1 werden ausdrücklich in den Umfang der vorliegenden Druckschrift inkorporiert. Entscheidend für den Sacktransport bei modernen Maschinen ist das zuverlässige taktweise Verbringen der bereits vereinzelten Säcke (= Schlauchstück mit Bodennaht) von Station zu Station mit den vorgenannten Greifmitteln 10, 11 oder 21 , 22. Hierbei bewerkstelligen die Greifmittel in der Regel einen geradlinigen Transport in Richtung der Transportrichtung z (Ausnahme natürlich der Quertransport in x-Richtung). Bei modernen Maschinen wie der in der EP 1 201 539 B1 gezeigt ergreifen die Greiferzangen oder Greiferzangenpaare 10,11 die Sacköffnung an ihren Enden. Beim Strammziehen der Sacköffnung berühren sich die Sackwandungen, wobei sie einen rechten Winkel mit der Transportrichtung z bilden, also in x-Richtung ausgerichtet sind. Dies entspricht auch der Förderrichtung (z) und Orientierung der Wandungen des Schlauches 5 (in x-Richtung) nach und während der Abwicklung. Vor allem in den Figuren 1 und 2 soll noch einmal die Abfolge der Bearbeitungsstationen deutlich gemacht werden.Figures 1 to 4 and 7 show sketches of inventive machines 2, in which the transport means 6, 10, 11, 12, 21, 22 and the individual processing stations 4, 7, 9, 12, 13 were shown only stylized. For a more detailed description of these objects, reference is made in particular to EP 1 201 539 B1, which has already been cited and incorporated several times, and to the likewise mentioned EP 1 459 981 A1 and US Pat. No. 6,401,439, which have more detailed descriptions and figures in this connection. This advice applies in particular also with respect to the gripper tongs and gripper tongs 10, 11 as well as the type and direction (especially z) in which they 10, 1 1 transport the bags 1 through the machine 2. The relevant passages of EP 1 201 539 B1 are also expressly incorporated in the scope of the present document. Decisive for the bag transport in modern machines is the reliable intermittent transfer of already isolated sacks (= hose piece with bottom seam) from station to station with the aforementioned gripping means 10, 11 or 21, 22. Here accomplish the gripping means usually a straight line Transport in the direction of transport z (exception, of course, the transverse transport in the x direction). In modern machines, such as those shown in EP 1 201 539 B1, the gripper tongs or pair of gripper tongs 10, 11 grip the bag opening at their ends. When tightening the bag opening, the bag walls touch, forming a right angle with the transport direction z, so are aligned in the x direction. This also corresponds to the conveying direction (z) and orientation of the walls of the tube 5 (in the x-direction) after and during unwinding. Especially in Figures 1 and 2, once again the sequence of processing stations should be made clear.
Nach der Abwicklung 4, in der ein Kunststoffschlauch 5 von einer Rolle 6 abgewickelt wird, wird eine Querschweißung an dem Schlauch 5 vorgenommen und dieser wird durch einen Quertrennschnitt vereinzelt. Die beiden letzteren Bearbeitungsschritte finden in der Querschweiß- und Trennstation 7 statt. Dann erfolgt der Quertransport mit Hilfe von Greifmitteln, die eben auch eine Bewegung in x-Richtung vornehmen können. Diese sind hier nur durch den Pfeil 8 skizziert. Nach dem Quertransport gelangt der Schlauch 1 in die Abfüllstation 9, in der die Säcke 1 befüllt werden. Anschließend erfolgt ein Verschließen der Säcke in der Verschließstation 12, in der in der Regel durch eine weitere Querschweißung eine Kopfnaht des Sackes gebildet wird. Die Skizzen 3 und 4 zeigen einen alternativen Aufbau einer FFS- Maschine, bei der zwischen der Quertrennstation 7 und der Befüllstation 9 eine Zwischen- oder Übergabestation 13 vorgesehen ist. In dem dargestellten Fall ist sie der zweiten Gruppe von Bearbeitungsstationen 9, 12 zugeordnet, die wie die erste Gruppe von Bearbeitungsstationen 4, 7 in der horizontalen Ebene, die hier von den x- und z-Koordinaten gebildet wird, in Transportrichtung der Säcke z geradlinig hintereinander angeordnet sind. In beiden gezeigten Ausführungsbeispielen enthält die erste Gruppe von Bearbeitungsstationen 4, 7 damit die auch gemeinsam als Sackherstellteil 3 bezeichneten Komponenten 4, 7, die nach oben offene Säcke fertigen.After the settlement 4, in which a plastic tube 5 is unwound from a roll 6, a transverse weld on the tube 5 is made and this is separated by a cross-cutting cut. The two latter processing steps take place in the transverse welding and separating station 7. Then the transverse transport takes place with the aid of gripping means, which can also perform a movement in the x-direction. These are outlined here only by the arrow 8. After the transverse transport of the tube 1 enters the filling station 9, in which the bags 1 are filled. Subsequently, the bags are closed in the closing station 12, in which a top seam of the bag is usually formed by a further transverse welding. Sketches 3 and 4 show an alternative construction of an FFS machine, in which an intermediate or transfer station 13 is provided between the cross-cutting station 7 and the filling station 9. In the illustrated case, it is associated with the second group of processing stations 9, 12 which, like the first group of processing stations 4, 7 in the horizontal plane formed here by the x and z coordinates, are straight in the transport direction of the bags z arranged one behind the other. In both exemplary embodiments shown, the first group of processing stations 4, 7 thus includes the components 4, 7, which are also referred to collectively as sack-making part 3 and which produce bags which are open at the top.
Weitere Bearbeitungsstationen - wie zum Beispiel eine Rüttelstation zum Verdichten des Füllmaterials und/oder ein Förderband zum Weitertransport und der Abstützung der befüllten Säcke - sind in den Figuren nicht dargestellt, können aber als Bearbeitungsstationen im Sinne der vorliegenden Anmeldung gelten.Other processing stations - such as a Rüttelstation for compacting the filling material and / or a conveyor belt for further transport and the support of the filled bags - are not shown in the figures, but may be considered as processing stations in the context of the present application.
Zur Verdeutlichung der Funktion der Zwischenstation sind in den Figuren 5 und 6 Greiferzangen 10 und 11 dargestellt. Bei ihnen 10, 11 handelt es sich um diejenigen Transportmittel, die die Säcke 1 im Bereich der Abfüllstation 9 halten und weitertransportieren. Die Zuführung der Säcke zur Abfüllstation 9 erfolgt in Figur 5 damit durch die durch den Pfeil 8 symbolisierte Quertransportvorrichtung. Diese umfasst dazu nicht dargestellte, aber geeignete Greifmittel, die den Quertransport in x-Richtung übernehmen. In Figur 6 ist wieder ein Ausführungsbeispiel mit einer Zwischenstation 13 dargestellt. Hier übergibt die Quertransportvorrichtung 8 die Säcke 1 zunächst dem Greiferzangenpaar 21 und 22. Diese beiden Greiferzangen übernehmen dann den Transport in die Sacktransportrichtung z, die hier auch durch die Pfeile 18 angedeutet ist. Durch diesen Transport durch dieses Greiferzangenpaar 21 , 22 gelangen die Säcke 1 wieder in den Bereich der Füllstation 9, in dem das andere Greiferzangenpaar 10, 11 wieder in derselben Weise wie in Figur 5 den Weitertransport der Säcke 1 übernimmt. Ein Charakteristikum des Transports von Säcken 1 oder Sackbestandteilen in modernen FFS-Maschinen, wie sie zum Beispiel in der EP 1 201 539 B1 gezeigt sind, besteht - wie schon mehrfach erwähnt - in der Verwendung von Greiferzangenpaaren oder auch einzelnen Greiferzangen 10, 11 , 21 , 22, die Säcke in der in Figur 8 gezeigten Weise transportieren:To clarify the function of the intermediate station, gripper tongs 10 and 11 are shown in FIGS. In them 10, 11 are those means of transport that hold the sacks 1 in the region of the filling station 9 and further transport. The feeding of the bags to the filling station 9 takes place in Figure 5 so that symbolized by the arrow 8 cross-transport device. This includes not shown, but suitable gripping means that take over the transverse transport in the x direction. FIG. 6 again shows an exemplary embodiment with an intermediate station 13. Here, the transverse transport device 8 passes the sacks 1 first to the pair of gripper tongs 21 and 22. These two gripper tongs then take over the transport in the sack transporting direction z, which is also indicated here by the arrows 18. As a result of this transport through this pair of gripper tongs 21, 22, the sacks 1 again reach the area of the filling station 9, in which the other pair of gripper tongs 10, 11 takes over the further transport of the sacks 1 in the same way as in FIG. A characteristic of the transport of sacks 1 or sack components in modern FFS machines, as shown, for example, in EP 1 201 539 B1, consists - as already mentioned several times - in the use of pair of gripper tongs or individual gripper tongs 10, 11, 21 , 22, which transport bags in the manner shown in Figure 8:
Bei solchen Maschinen (wie der in der EP 1 201 539 B1 ) ergreifen die Greiferzangen oder Greiferzangenpaare 10,11 die Sacköffnung an ihren Enden 23, 24. Beim Strammziehen der Sacköffnung berühren sich die Sackwandungen 25, 26, wobei sie einen rechten Winkel mit der Transportrichtung z bilden und entlang der x-Richtung verlaufen. Figur 9 verdeutlicht noch einmal die Bedeutung der zuletzt eingeführten Begriffe anhand einer Draufsicht auf eine „strammgezogene" Sacköffnung, wobei aus darstellerischen Gründen darauf verzichtet wurde, eine Berührung zwischen den beiden Sackwandungen 24 und 25 darzustellen. Klar ist jedoch, dass die Sackwandungen in dieser Transportsituation in x-Richtung ausgerichtet sind, während der Sack in z-Richtung transportiert wird. Es sind auch Maschinen bekannt, bei denen die Funktion eines Greiferzangenpaares von einer einzelnen Greiferzange übernommen wird, bei der jedoch der Transport der Säcke 1 und ihre Ausrichtung während des Transports zur Transportrichtung z dieselbe ist. Figur 7 zeigt im Wesentlichen eine erfindungsgemäße Maschine 2, die entsprechend dem in den Figuren 3 und 4 dargestellten Ausführungsbeispiel aufgebaut ist. Insbesondere ist dem Sackfüll- und -schließteil 20, das die Füllstation 9 und die Verschließstation 12 enthält und hier die erste zweite Gruppe von Bearbeitungsstationen bildet, eine Zwischenstation 13 zugeordnet. Allerdings verfügt die Maschine 2 in Figur 7 über zwei solcher Sackfüll- undIn such machines (as in EP 1 201 539 B1), the gripper tongs or gripper tongs 10, 11 engage the sack opening at their ends 23, 24. When the sack opening is tightened, the sack walls 25, 26 come into contact with each other Form transport direction z and run along the x-direction. 9 again illustrates the meaning of the terms introduced last on the basis of a top view of a "tightly drawn" bag opening, wherein for illustrative reasons it has been omitted to depict a contact between the two bag walls 24 and 25. However, it is clear that the bag walls in this transport situation aligned in the x-direction, while the bag is transported in the z-direction. There are also known machines in which the function of a gripper pair of grippers is taken over by a single gripper, but in which the transport of the bags 1 and their orientation during transport to the transport direction z is the same. FIG. 7 essentially shows a machine 2 according to the invention which is constructed in accordance with the exemplary embodiment illustrated in FIGS. 3 and 4. In particular, the bag filling and closing part 20, which contains the filling station 9 and the closing station 12 and here forms the first second group of processing stations, is assigned an intermediate station 13. However, the machine 2 in Figure 7 has two such Sackfüll- and
-schließteile 20. Diese können auch (in Bezug auf die Längsachse der Maschine 2) spiegelbildlich aufgebaut sein. Es zeigen sich in diesem Zusammenhang die Vorteile eines modularen Aufbaus des Sackherstell- 3 und Sackfüll- und Schließteils 20. In den beiden Abfüllstationen 9 können damit gleichzeitig oder alternierend Säcke abgefüllt werden. In der Regel wird es vorteilhaft sein, wenn sich die Abfüllvorgänge der Säcke 1 in den beiden Abfüllstationen 9 zeitlich überlappen. These can also be constructed in mirror image (with respect to the longitudinal axis of the machine 2). In this context, the advantages of a modular construction of the sack making and bag filling and closing part 20 are evident. In the two filling stations 9, sacks can thus be filled simultaneously or alternately. As a rule, it will be advantageous if the filling operations of the sacks 1 in the two filling stations 9 overlap in time.
