Definitions
- the invention relates to a method and apparatus for positioning valve or cover sheets relative to tubing components.
- valve or cover sheets relative to components of tubing is particularly important in the manufacture of sacks and bags.
- bags which are often provided for later filling with bulk materials, for example, with building materials such as cement, are usually prepared by a section of a hose is transported transversely to the tube axis, the end areas are reared, a valve sheet applied, for example glued Then, parts of the wound end portions are folded over to close the sack end, and finally bottom sheets are applied to the so formed bottoms.
- one of the two ends can be formed in a different way, as it is often not necessary to provide a valve at both ends.
- On ground cover sheets if the strength of a soil is already sufficient, can be dispensed with.
- Such a bag is later filled by the or a valve.
- the correct position of the valve or cover slip is important, but also the correct position of imprints, coatings such as glue jobs and also pre-breaks or creases that mark the later fold lines.
- the production of such bags from pieces of tubing takes place in devices which are often referred to as Bodenlegevorraumen.
- the hose pieces are transported transversely to its bag longitudinal axis and in the tube level usually horizontally in a transport device, wherein they are held immobile relative to the transport device.
- the hose pieces are often clamped in the region of their two ends between the belt of so-called double belt conveyors.
- the valve leaflet and the ground cover sheets are transported by other transport devices to the hose pieces, this case also double conveyors or cylinders are provided, on the surfaces of the valve or bottom cover sheets are transported.
- Such cylinders can be equipped with suckers or pliers.
- all transport devices must be adjusted and coordinated so that the valve leaflets or bottom cover sheets are applied exactly to the nominal positions of the components of the tube pieces in order to be fastened there.
- the object is achieved by a method according to claim 1 and a device according to claim 7.
- images of the components of a plurality of pieces of tubing and / or of the aggregates acting on the pieces of tubing or the components applied to the piece of tubing are received. These images can be taken after various manufacturing steps during bag making. In this case, for example, each bag can be imaged or even every nth bag (n> 1). One or more images can be taken of a sack, depending on which positions are to be determined. So it may be useful to take pictures of the grooved hose pieces before the valve sheet is glued. After sticking the valve leaflet another picture can be taken.
- the actual positions of the valve or cover sheets, imprints, coatings and / or embossments are determined relative to a reference point of the hose piece.
- a reference point is about the leading triangle tip, which arises when a flat lying piece of hose, which is transversely to a tube axis, but in the tube plane promoted, has been raised at its ends.
- the mounted end is then parallel to a plane which is perpendicular to the tube plane and orthogonal to the tube axis.
- the positions in the plane of the drawn-up end are preferably determined, the orthogonal positions to this plane are of secondary importance.
- the difference between the actual positions and the associated setpoint positions is determined in order to obtain the deviations from the setpoint positions.
- the calculated deviation is then followed by a value by which the valve or cover sheets, imprints, coatings and / or embossments are displaced relative to the constituents of pieces of tubing. This can be done by moving the aggregates that make the aforementioned additions or entries. Alternatively or additionally, the means that transport the pieces of hose, such as conveyor belts, can be moved. The means of transport can also be accelerated or decelerated if the determined deviation is in the transport direction of the hose pieces.
- the value that follows from the determined deviation may be the determined deviation itself.
- the deviation is determined on a piece of tubing to which, however, no influence can be taken.
- the position changes thus affect the following pieces of hose.
- a change in position can lead to larger deviations for the following pieces of tubing, ie reverse the desired effect.
- the value that follows from the determined deviation, from a plurality of Determine deviations, with an average being formed from this plurality is calculated by averaging over several recorded pieces of tubing.
- the position of the relevant unit is changed, so that the relevant actual position is corrected by the calculated mean value. This correction can also be made if this mean value is within the product tolerance.
- the position of the unit may not only mean the spatial position relative to the piece of hose, but in particular the phase position relative to the transport device which transports the pieces of hose.
- the number of pieces of tubing over which the average value is formed is advantageously the number of lengths of tubing transported during one revolution of a belt for transporting the pieces of tubing.
- an average deviation is not calculated from the ascertained deviations, but a deviation function is determined.
- This deviation function can be dependent on the time.
- the function value of this function at a fixed point in time may be the deviation value with respect to a single bag or a single piece of tubing, but also the deviation values of bags already measured or still to be measured may be taken into account (moving averaging).
- the function is also a periodic function.
- a correction of the actual positions can then also be carried out periodically by means of a control and regulation unit, wherein the value which follows from the determined deviation and which is used for setting the positions, the function value of the function is at a certain time.
- the recording of images is carried out by one or more cameras that may be attached to the machine frame of Bodenlegevorraum. These images taken by the cameras are transmitted to an evaluation and arithmetic unit which determines the positions of the respective reference point and the actual positions from the recorded images, calculates deviations from the desired positions and determines the mean values or functions. These mean values are then transmitted to a control unit, which activates actuators with which the layers of the imprints, coatings, embossings, valve leaflets and / or cover sheet labels can be changed or introduced into aggregates. These actuators may be, for example, motor-adjustable differentials, which can be adjusted during ongoing production, so that the correction of the positions can be done without interrupting production.
- differential gears are usually used to change the phase angles and / or the rotational speeds of two driven by a drive components relative to each other.
- a Bodenlegevorraum often a plurality of units is driven by a single drive, which drives a so-called vertical shaft, from each of which a torque is tapped for an aggregate.
- the aforementioned process according to the invention can be carried out repeatedly during bag production in order to avoid waste as completely as possible.
- Fig. 1a shows a sequence of process steps for molding a valve bottom to a piece of hose.
- Each method step is carried out in an assigned workstation, which are marked with 1 to 7.
- the hose pieces 8 are conveyed by a double belt conveyor 9 to the individual workstations, the hose axis extending transversely to the conveying direction, but in the conveying plane.

Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Positionieren von Ventil- oder Deckblattzetteln relativ zu Bestandteilen von Schlauchstücken.The invention relates to a method and apparatus for positioning valve or cover sheets relative to tubing components.
Die Positionierung von Ventil- oder Deckblattzetteln relativ zu Bestandteilen von Schlauchstücken ist insbesondere bei der Herstellung von Säcken und Beuteln wichtig. Derartige Säcke, die häufig zum späteren Befüllen mit Schüttgütern, beispielsweise mit Baustoffen wie Zement, vorgesehen sind, werden in der Regel dadurch hergestellt, dass ein Abschnitt eines Schlauches quer zu der Schlauchachse transportiert wird, die Endbereiche aufgezogen werden, ein Ventilzettel aufgebracht, beispielsweise aufgeklebt wird, sodann Teile der aufgezogenen Endbereiche umgeklappt werden, um das Sackende zu verschließen, und schließlich Bodendeckblätter auf die so gebildeten Böden aufgebracht werden. Bei Bedarf kann eines der beiden Enden auf eine andere Art geformt werden, ebenso ist es oft nicht erforderlich, an beiden Enden ein Ventil vorzusehen. Auf Bodendeckblätter kann, wenn die Festigkeit eines Bodens bereits ausreichend ist, verzichtet werden. Ein solcher Sack wird später durch das oder ein Ventil befüllt. Für die Qualität der Säcke ist jedoch oft nicht nur die korrekte Lage der Ventil- oder Deckblattzettel wichtig, sondern auch die korrekte Lage von Aufdrucken, Beschichtungen wie etwa Leimaufträge und auch Vorbrüche bzw. Rillungen, die die späteren Falzlinien markieren. Die Herstellung derartiger Säcke aus Schlauchstücken erfolgt in Vorrichtungen, die häufig als Bodenlegevorrichtungen bezeichnet werden.The positioning of valve or cover sheets relative to components of tubing is particularly important in the manufacture of sacks and bags. Such bags, which are often provided for later filling with bulk materials, for example, with building materials such as cement, are usually prepared by a section of a hose is transported transversely to the tube axis, the end areas are reared, a valve sheet applied, for example glued Then, parts of the wound end portions are folded over to close the sack end, and finally bottom sheets are applied to the so formed bottoms. If necessary, one of the two ends can be formed in a different way, as it is often not necessary to provide a valve at both ends. On ground cover sheets, if the strength of a soil is already sufficient, can be dispensed with. Such a bag is later filled by the or a valve. For the quality of the sacks, however, often not only the correct position of the valve or cover slip is important, but also the correct position of imprints, coatings such as glue jobs and also pre-breaks or creases that mark the later fold lines. The production of such bags from pieces of tubing takes place in devices which are often referred to as Bodenlegevorrichtungen.
Zur Herstellung der beschriebenen Säcke werden die Schlauchstücke quer zu ihrer Sacklängsachse und in der Schlauchebene zumeist horizontal in einer Transporteinrichtung transportiert, wobei sie relativ zur Transportvorrichtung unbeweglich gehalten werden. Dazu werden die Schlauchstücke häufig im Bereich ihrer beiden Enden zwischen den Riemen von so genannten Doppelbandförderern klemmend gehalten. Die Ventilzettel und die Bodendeckblätter werden von anderen Transportvorrichtungen an die Schlauchstücke herantransportiert, wobei hierzu fallweise ebenfalls Doppelförderer oder auch Zylinder vorgesehen sind, auf deren Oberflächen die Ventil- oder Bodendeckblätter transportiert werden. Solche Zylinder können dazu mit Saugern oder Zangen ausgestattet sein. Zu Beginn des Produktionsprozesses müssen alle Transporteinrichtungen derart einjustiert und aufeinander abgestimmt werden, dass die Ventilzettel oder Bodendeckblätter genau an den Sollpositionen der Bestandteile der Schlauchstücke angelegt werden, um dort befestigt zu werden. Dabei spielt nicht nur die Lage der Zettel und Blätter auf beziehungsweise in den Transporteinrichtungen eine Rolle, sondern auch die Transportgeschwindigkeiten. Zur Abstimmung und Einjustierung werden an Vorrichtungen nach dem Stand der Technik bei Produktionsbeginn vom Maschinenführer Stichproben entnommen und vermessen, um die Abweichungen der tatsächlichen Positionen von den Sollpositionen zu ermitteln. Anschließend werden die einzelnen Transporteinrichtungen entsprechend den ermittelten Abweichungen nachgestellt, um die Abweichungen zu minimieren. Justagearbeiten sind oft auch an den Vorrichtungen zur Bedruckung, Beschichtung oder Prägung notwendig! Nachteilig ist dabei, dass der Justageprozess zeitraubend ist und dass die Säcke zur Kontrolle beschädigt oder gar zerstört werden.For the production of the bags described the hose pieces are transported transversely to its bag longitudinal axis and in the tube level usually horizontally in a transport device, wherein they are held immobile relative to the transport device. For this purpose, the hose pieces are often clamped in the region of their two ends between the belt of so-called double belt conveyors. The valve leaflet and the ground cover sheets are transported by other transport devices to the hose pieces, this case also double conveyors or cylinders are provided, on the surfaces of the valve or bottom cover sheets are transported. Such cylinders can be equipped with suckers or pliers. At the beginning of the production process, all transport devices must be adjusted and coordinated so that the valve leaflets or bottom cover sheets are applied exactly to the nominal positions of the components of the tube pieces in order to be fastened there. Not only the location of the sheets and sheets on or in the transport facilities plays a role, but also the transport speeds. For tuning and adjustment, samples are taken and measured on prior art devices at the start of production by the operator to determine the deviations of the actual positions from the desired positions. Subsequently, the individual transport devices are readjusted according to the determined deviations in order to minimize the deviations. Adjustment work is often also necessary on the devices for printing, coating or embossing! The disadvantage here is that the adjustment process is time-consuming and that the bags are damaged for control or even destroyed.
Zur Überwachung der Abweichungen schlägt die
Bei der Anwendung dieser Vorgehensweise hat sich in der Vergangenheit jedoch gezeigt, dass sich die geometrischen Produkttoleranzen, also die Abweichungen der Istpositionen beziehungsweise der ermittelten Positionen von den Sollpositionen häufig in einem großen Rahmen bewegen und daher viel Ausschuss produziert wird. Zwar kann in solchen Fällen die Bodenlegevorrichtung nachjustiert werden, jedoch muss hierzu die Produktion erneut unterbrochen werden.In the application of this procedure, however, it has been shown in the past that the geometric product tolerances, that is to say the deviations of the actual positions or of the determined positions Of the target positions often move in a large frame and therefore much rejects is produced. Although in such cases, the Bodenlegevorrichtung be readjusted, but this production must be interrupted again.
Daher ist es die Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung vorzuschlagen, mit denen sich ohne zusätzlichen Zeitaufwand die Produkttoleranzen weiter minimieren lassen und sich damit der Ausschussanteil reduzieren lässt.It is therefore the object of the present invention to propose a method and a device with which the product tolerances can be further minimized without additional expenditure of time and thus the scrap content can be reduced.
Die Aufgabe wird gelöst durch ein Verfahren nach Anspruch 1 und einer Vorrichtung nach Anspruch 7.The object is achieved by a method according to
Demnach werden zunächst Bilder der Bestandteile von mehreren Schlauchstücken und/oder von den Aggregaten, die auf die Schlauchstücke einwirken, oder den Bestandteilen, die auf das Schlauchstück aufgebracht werden, aufgenommen. Diese Bilder können nach verschiedenen Herstellungsschritten während der Sackherstellung aufgenommen werden. Dabei kann beispielsweise jeder Sack abgebildet werden oder auch nur jeder n-te Sack (n>1). Von einem Sack können ein oder mehrere Bilder aufgenommen werden, und zwar davon abhängig, welche Positionen bestimmt werden sollen. So kann es sinnvoll sein, Bilder von den gerillten Schlauchstücken aufzunehmen, bevor der Ventilzettel aufgeklebt wird. Nach dem Aufkleben des Ventilzettels kann ein weiteres Bild aufgenommen werden.Accordingly, first of all, images of the components of a plurality of pieces of tubing and / or of the aggregates acting on the pieces of tubing or the components applied to the piece of tubing are received. These images can be taken after various manufacturing steps during bag making. In this case, for example, each bag can be imaged or even every nth bag (n> 1). One or more images can be taken of a sack, depending on which positions are to be determined. So it may be useful to take pictures of the grooved hose pieces before the valve sheet is glued. After sticking the valve leaflet another picture can be taken.
In einem zweiten Schritt werden die Istpositionen der Ventil- oder Deckblattzettel, Aufdrucke, Beschichtungen und/oder Prägungen relativ zu einem Referenzpunkt des Schlauchstücks ermittelt. Ein solcher Referenzpunkt ist etwa die voraus laufende Dreieckspitze, die entsteht, wenn ein flach liegendes Schlauchstück, welches quer zu einer Schlauchachse, aber in der Schlauchebene gefördert wird, an seinen Enden aufgezogen wurde. Das aufgezogene Ende liegt dann parallel zu einer Ebene, die senkrecht zur Schlauchebene und orthogonal zur Schlauchachse liegt. Dabei werden vorzugsweise die Positionen in der Ebene des aufgezogenen Endes ermittelt, die Positionen in orthogonaler Richtung zu dieser Ebene besitzen eher eine untergeordnete Bedeutung. Anschließend wird die Differenz zwischen den Istpositionen und den zugehörigen Sollpositionen ermittelt, um die Abweichungen von den Sollpositionen zu erhalten.In a second step, the actual positions of the valve or cover sheets, imprints, coatings and / or embossments are determined relative to a reference point of the hose piece. Such a reference point is about the leading triangle tip, which arises when a flat lying piece of hose, which is transversely to a tube axis, but in the tube plane promoted, has been raised at its ends. The mounted end is then parallel to a plane which is perpendicular to the tube plane and orthogonal to the tube axis. In this case, the positions in the plane of the drawn-up end are preferably determined, the orthogonal positions to this plane are of secondary importance. Subsequently, the difference between the actual positions and the associated setpoint positions is determined in order to obtain the deviations from the setpoint positions.
Wenn jedoch beispielsweise ein aufzuklebendes Deckblatt auf dem dieses zuführenden Zylinder, jedoch kein Referenzpunkt des Schlauchstücks ebenfalls gleichzeitig abgebildet wird, so muss die Istposition in Bezug zu einem mit erfassten Referenzpunkt gesetzt werden, dessen Lage im Raum bekannt ist. Um nun das Bild in Bezug zu dem Schlauchstück setzen zu können, kann das Schlauchstück, wenn es einen bestimmten Ort passiert, die Aufnahme auslösen.However, if, for example, a cover sheet to be adhered is also imaged simultaneously on the cylinder feeding thereto, but no reference point of the hose piece is to be set, the actual position must be related to a detected reference point whose position in space is known. In order to be able to place the image in relation to the hose piece, the hose piece, when it passes a certain place, trigger the recording.
Aus der berechneten Abweichung folgt nun ein Wert, um den die Ventil- oder Deckblattzettel, Aufdrucke, Beschichtungen und/oder Prägungen relativ zu den Bestandteilen von Schlauchstücken verschoben werden. Dies kann durch Verschieben der Aggregate erfolgen, die die genannten Auf- oder Einbringungen vornehmen. Alternativ oder zusätzlich können auch die Mittel, die die Schlauchstücke transportieren, wie etwa Transportriemen, verschoben werden. Die Transportmittel können auch beschleunigt oder abgebremst werden, wenn die ermittelte Abweichung in der Transportrichtung der Schlauchstücke liegt.The calculated deviation is then followed by a value by which the valve or cover sheets, imprints, coatings and / or embossments are displaced relative to the constituents of pieces of tubing. This can be done by moving the aggregates that make the aforementioned additions or entries. Alternatively or additionally, the means that transport the pieces of hose, such as conveyor belts, can be moved. The means of transport can also be accelerated or decelerated if the determined deviation is in the transport direction of the hose pieces.
Der Wert, der aus der ermittelten Abweichung folgt, kann die ermittelte Abweichung selbst sein.The value that follows from the determined deviation may be the determined deviation itself.
Die Abweichung wird an einem Schlauchstück ermittelt, auf das aber kein Einfluss mehr genommen werden kann. Die Positionsveränderungen betreffen also folgende Schlauchstücke. Eine Positionsveränderung kann jedoch für folgende Schlauchstücke zu größeren Abweichungen führen, also den gewünschten Effekt umkehren.The deviation is determined on a piece of tubing to which, however, no influence can be taken. The position changes thus affect the following pieces of hose. A change in position, however, can lead to larger deviations for the following pieces of tubing, ie reverse the desired effect.
Daher ist in einer vorteilhaften Ausführungsform der Erfindung vorgesehen, den Wert, der aus der ermittelten Abweichung folgt, aus einer Mehrzahl von Abweichungen zu ermitteln, wobei aus dieser Mehrzahl ein Mittelwert gebildet wird. Es wird also eine mittlere Abweichung durch eine Mittelwertbildung über mehrere aufgenommene Schlauchstücke berechnet. Anschließend wird die Lage des betreffenden Aggregats verändert, so dass die betreffende Istposition um den berechneten Mittelwert korrigiert wird. Diese Korrektur kann auch erfolgen, wenn dieser Mittelwert innerhalb der Produkttoleranz liegt. Mit der Lage des Aggregats kann nicht nur die räumliche Lage relativ zum Schlauchstück gemeint sein, sondern insbesondere auch die Phasenlage relativ zu der Transportvorrichtung, welche die Schlauchstücke transportiert.Therefore, in an advantageous embodiment of the invention, the value that follows from the determined deviation, from a plurality of Determine deviations, with an average being formed from this plurality. Thus, a mean deviation is calculated by averaging over several recorded pieces of tubing. Subsequently, the position of the relevant unit is changed, so that the relevant actual position is corrected by the calculated mean value. This correction can also be made if this mean value is within the product tolerance. The position of the unit may not only mean the spatial position relative to the piece of hose, but in particular the phase position relative to the transport device which transports the pieces of hose.
Die Anzahl der Schlauchstücke, über die der Mittelwert gebildet wird, ist vorteilhafterweise die Anzahl der Schlauchstücke, die während eines Umlaufs eines Riemens zum Transport der Schlauchstücke transportiert werden.The number of pieces of tubing over which the average value is formed is advantageously the number of lengths of tubing transported during one revolution of a belt for transporting the pieces of tubing.
In einer weiteren vorteilhaften Ausführungsform wird aus den ermittelten Abweichungen nicht eine mittlere Abweichung berechnet, sondern eine Abweichungsfunktion ermittelt. Diese Abweichungsfunktion kann abhängig von der Zeit sein. Der Funktionswert dieser Funktion zu einem festen Zeitpunkt kann dabei der Abweichungswert in Bezug auf einen einzelnen Sack bzw. ein einzelnes Schlauchstück sein, es können aber auch die Abweichungswerte von bereits vermessenen bzw. noch zu vermessenen Säcken berücksichtigt werden (gleitende Mittelwertbildung).In a further advantageous embodiment, an average deviation is not calculated from the ascertained deviations, but a deviation function is determined. This deviation function can be dependent on the time. The function value of this function at a fixed point in time may be the deviation value with respect to a single bag or a single piece of tubing, but also the deviation values of bags already measured or still to be measured may be taken into account (moving averaging).
Mithilfe der aufgestellten Funktion kann dann nicht nur auf die bereits ermittelten Abweichungen reagiert, sondern auch zukünftige Abweichungen vorausgesagt werden. Dies ist insbesondere dann vorteilhaft, wenn es in der Bodenlegevorrichtungen zu periodischen Abweichungen kommt, beispielsweise durch Gleichlaufschwankungen der Transportriemen oder des Antriebsmotors. Daher ist in einer vorteilhaften Ausführungsform auch die Funktion eine periodische Funktion. Eine Korrektur der Istpositionen kann dann ebenfalls periodisch mittels einer Steuer- und Regeleinheit erfolgen, wobei der Wert, der aus der ermittelten Abweichung folgt und der zur Einstellung der Positionen herangezogen wird, der Funktionswert der Funktion zu einem bestimmten Zeitpunkt ist.With the help of the established function, it is not only possible to react to deviations already determined, but also to predict future deviations. This is particularly advantageous when it comes to periodic deviations in Bodenlegevorrichtungen, for example, by synchronous fluctuations of the conveyor belt or the drive motor. Therefore, in an advantageous embodiment, the function is also a periodic function. A correction of the actual positions can then also be carried out periodically by means of a control and regulation unit, wherein the value which follows from the determined deviation and which is used for setting the positions, the function value of the function is at a certain time.
Die Aufnahme von Bildern erfolgt durch eine oder mehrere Kameras, die am Maschinengestell der Bodenlegevorrichtung angebracht sein können. Diese von den Kameras aufgenommenen Bilder werden einer Auswerte- und Recheneinheit übermittelt, die aus den aufgenommenen Bildern die Lagen des jeweiligen Referenzpunktes und die Istpositionen ermittelt, die Abweichungen von den Sollpositionen berechnet sowie die Mittelwerte bzw. Funktionen bestimmt. Diese Mittelwerte werden dann an eine Steuereinheit übermittelt, die Stellorgane ansteuert, mit welchen sich die Lagen der die Aufdrucke, Beschichtungen, Prägungen, Ventilzetteln und/oder Deckblattzetteln auf- oder einbringenden Aggregate verändern lassen. Diese Stellorgane können beispielsweise motorisch verstellbare Differenziale sein, die sich während der laufenden Produktion verstellen lassen, so dass die Korrektur der Positionen erfolgen kann, ohne die Produktion zu unterbrechen. Solche auch als Ausgleichsgetriebe bezeichneten Differenziale werden in der Regel eingesetzt, um die Phasenlagen und/oder die Drehgeschwindigkeiten von zwei von einem Antrieb angetriebenen Komponenten relativ zueinander zu verändern. An einer Bodenlegevorrichtung wird häufig eine Mehrzahl von Aggregaten mittels eines einzigen Antriebs angetrieben, welcher eine so genannte Königswelle antreibt, von der jeweils ein Drehmoment für ein Aggregat abgegriffen wird.The recording of images is carried out by one or more cameras that may be attached to the machine frame of Bodenlegevorrichtung. These images taken by the cameras are transmitted to an evaluation and arithmetic unit which determines the positions of the respective reference point and the actual positions from the recorded images, calculates deviations from the desired positions and determines the mean values or functions. These mean values are then transmitted to a control unit, which activates actuators with which the layers of the imprints, coatings, embossings, valve leaflets and / or cover sheet labels can be changed or introduced into aggregates. These actuators may be, for example, motor-adjustable differentials, which can be adjusted during ongoing production, so that the correction of the positions can be done without interrupting production. Such also referred to as differential gears differentials are usually used to change the phase angles and / or the rotational speeds of two driven by a drive components relative to each other. At a Bodenlegevorrichtung often a plurality of units is driven by a single drive, which drives a so-called vertical shaft, from each of which a torque is tapped for an aggregate.
Das vorgenannte, erfindungsgemäße Verfahren lässt sich während der Sackproduktion ständig wiederholt durchführen, um Ausschuss möglichst gänzlich zu vermeiden.The aforementioned process according to the invention can be carried out repeatedly during bag production in order to avoid waste as completely as possible.

Fig. 1 a zeigt eine Abfolge von Verfahrensschritten zur Anformung eines Ventilbodens an ein Schlauchstück. Jeder Verfahrensschritt wird dabei in einer zugeordneten Arbeitsstation durchgeführt, die mit 1. bis 7. gekennzeichnet sind. Die Schlauchstücke 8 werden von einem Doppelbandförderer 9 zu den einzelnen Arbeitsstationen gefördert, wobei die Schlauchachse quer zur Förderrichtung, aber in der Förderebene verläuft. In der Arbeitsstation 1. wird das Schlauchende aufgezogen, so dass der nun offene Boden 10 in einer Ebene, die im Wesentlichen orthogonal zur Schlauchachse verläuft, liegt. In der Arbeitsstation 2 wird ein Ventilzettel 11 auf den offenen Boden 10 aufgebracht. In der Arbeitsstation 3 wird ein weiterer Ventilzettel 12 aufgebracht. In der Arbeitsstation 4 werden auf nicht näher dargestellte Weise Bereiche des Bodens 10 mit Leim beschichtet. Anschließend erfolgt in der Arbeitsstation 5. das Zulegen der Böden, wobei aufgrund des aufgetragenen Leims Bereiche der Böden miteinander verkleben und so einen dauerhaften Boden bilden. In der Arbeitsstation 6 wird ein Bodendeckblatt 13 auf den zugelegten Boden aufgebracht. Abschließend wird in der Arbeitsstation 7 optional mittels eines Formatzylinders 14 ein Aufdruck auf das Bodendeckblatt aufgedruckt. Dazu kann der Formatzylinder 14 nicht dargestellte, erhabene Klischees tragen.Fig. 1a shows a sequence of process steps for molding a valve bottom to a piece of hose. Each method step is carried out in an assigned workstation, which are marked with 1 to 7. The
In der Fig. 1 b ist der Doppelbandförderer 9 noch einmal detaillierter dargestellt. Der Doppelbandförderer 9 umfasst zwei umlaufende, endlose Förderbänder 15, die über Umlenkrollen 16 geführt werden. Zum Transport der Schlauchstücke sind in Bereichen des Doppelbandförderers die beiden Förderbänder übereinander gelegt und werden durch mit Federkräften beaufschlagten Rollen 17 zusammengedrückt, so dass eine Verschiebung der Schlauchstücke relativ zu den Förderbändern vermieden wird. Der Antrieb der Förderbänder 15 ist exemplarisch für das untere Förderband 15 dargestellt. Der Antrieb umfasst einen nicht dargestellten Antriebsmotor, der die Antriebsscheibe 18 antreibt. Das Förderband 15 wird über die Scheiben 19 geführt, die so angeordnet sind, dass das Förderband 15 die Antriebsscheibe 18 mindestens über einen Winkel von 180° umschlingt.In Fig. 1 b of the
Die Fig. 2 zeigt verschiedene Parameter, die bei der Feststellung der Position des Ventilzettels 11, des Bodendeckblatts 13 und auch des Aufdrucks 20 relativ zum Boden 8 berücksichtigt und zur Minimierung der Fertigungstoleranzen im Rahmen der Erfindung veränderbar sind. Die Bezugspunkte des Bodens 8 für die entsprechenden Messungen zur Ermittlung der Positionen sind die Spitze 21 des in Laufrichtung z gesehen vorderen Bodendreiecks und die Mittellinie 22 des Boden, die parallel zur Laufrichtung z verläuft. Der Parameter a1 bezeichnet den Abstand der vorderen Kante des Bodendeckblatts 13 von der Spitze 21, der Parameter a2 den Abstand zwischen der Spitze 21 und der vorderen Kante des Aufdrucks (in Leserichtung) und der Parameter a3 den Abstand der hinteren Kante des Ventilblattes 11 von der Spitze 21. Um diese Parameter einzustellen und deren Toleranzen von den Sollwerten zu minimieren, sind die Phasenlagen der Antriebe der Transportvorrichtungen für den Deckblatttransport und den Ventilzetteltransport sowie die Phasenlage der Formatwalze. 14 relativ zum Doppelbandförderer verändert. Häufig werden all diese Komponenten von einem einzigen Antrieb angetrieben, wobei dieser Antrieb eine Maschinenwelle antreibt, von der Drehmoment zum Antrieb der einzelnen Transportvorrichtungen abgegriffen wird. Um die Phasenlage verändern zu können, ist ein motorisch verstellbares Überlagerungsgetriebe vorgesehen, wobei dessen Stellmotor in seiner Position erfassbar und regelbar ist. Haben einzelne der beschriebenen Komponenten einen eigenen Antriebsmotor, der unabhängig von der Maschinenwelle arbeitet, so ist die Drehlage dieses Antriebsmotors erfassbar bzw. regelbar. Dies geschieht in der Regel über an sich bekannte Drehgeber.Fig. 2 shows various parameters that are taken into account in determining the position of the
Die Parameter b1 und b2 bezeichnen den Abstand der oberen Kante des Bodendeckblatts und des Ventilzettels zur Mittellinie 22. Diese Positionen werden durch eine motorisch hervorgerufene Verschiebung der die Bodendeckblatt beziehungsweise Ventilzettel transportierenden Transporteinrichtungen relativ zum Doppelbandförderer eingestellt. Ähnliches gilt für den Parameter b4, welcher den Abstand der Oberkante des Aufdrucks zur Mittellinie 22 bezeichnet, wobei zu dessen Variation die Formatwalze axial verschoben wird. Der Parameter b3 beschreibt die Breite des Ventilzettels 11.
