Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Ankleben von in Schutzhüllen aufgenommenen Trinkhalmen an Getränkebehälter, insbesondere an Getränkebeutel, mit einer Einrichtung zum Zuführen eines von einer drehbar gelagerten Vorratsrolle abziehbaren Trinkhalmbandes, mit einer Schneidstation zum Abtrennen der eingehüllten Trinkhalme vom Trinkhalmband, mit einer Trinkhalmfördereinrichtung zum lagerichtigen Zuführen der durch Abtrennen vom Trinkhalmband vereinzelten Trinkhalme und zum Positionieren derselben gegenüber den Getränkebehältern in einer Anklebestation sowie mit einer Einrichtung zum Andrücken der Trinkhalme an die von einer Behälterfördereinrichtung zu der Anklebestation zugeführten Getränkebehälter.The invention relates to a device for gluing straws accommodated in protective sleeves to beverage containers, in particular to beverage bags, with a device for feeding a drinking straw band that can be pulled off a rotatably mounted supply roll, with a cutting station for separating the wrapped drinking straws from the drinking straw band, with a drinking straw conveyor device correct feeding of the straws separated by separation from the straw band and for positioning them in relation to the beverage containers in a gluing station and with a device for pressing the straws onto the beverage containers fed from a container conveyor to the gluing station.

Eine Vorrichtung dieser Art ist in der DE-A-2 902 899 beschrieben, bei der von einer Vorratsrolle ein Trinkhalmband mit quer zur Bandlängserstreckung in Parallellage zueinander und in untereinander gleichen Abständen angeordneten, jeweils für sich in Schutzhüllen aufgenommenen Trinkhalmen abgezogen wird und bei der von diesem Trinkhalmband aufeinanderfolgend je eine Schutzhülle mit jeweils einem umhüllten Trinkhalm abgetrennt sowie die abgetrennten Schutzhüllen dann einzeln an eine Wand eines von einer weiteren Fördereinrichtung zugeführten Getränkebehälters angeklebt werden.A device of this type is described in DE-A-2 902 899, in which a drinking straw band with crosswise to the lengthwise direction of the band is arranged in parallel to one another and at equal intervals from one another, in each case the straws which are accommodated in protective sleeves are withdrawn and from which This drinking straw band is successively separated from a protective cover, each with a covered drinking straw, and the separated protective covers are then individually glued to a wall of a beverage container supplied by a further conveying device.

Bei dieser vorbekannten Vorrichtung wird das Trinkhalmband über eine Zuführwalze mit in Parallellage zur Walzendrehachse im Walzenmantel angebrachten Längsnuten geführt, die auf einem Teilstück des Zuführweges von einer sich bogenförmig um den Walzenmantel herumerstreckenden Führung abgedeckt ist. Im Bereich dieser Führung ist ein intermittierend betätigbares Messer zum Abtrennen der einzelnen Schutzhüllen mit je einem in diesen aufgenommenen Trinkhalm vom Trinkhalmband angeordnet und im Auslaufbereich der Abdeckung wird je ein vereinzelter Trinkhalm mittels eines ebenfalls intermittierend betätigbaren Andrückers an eine Wand der taktgleich von einer Fördereinrichtung herangeführten Getränkebehälter angedrückt, und zwar in ein in einer vorhergehenden Station an die Wand des Getränkebehälters angespritztes Klebebett.In this previously known device, the straw band is guided over a feed roller with longitudinal grooves arranged in parallel with the axis of rotation of the roller in the roller shell, which is covered on part of the feed path by a guide extending in an arc around the roller shell. In the area of this guide, an intermittently operable knife for separating the individual protective sleeves, each with a drinking straw accommodated in it, is arranged from the drinking straw band, and in the outlet area of the cover, an individual drinking straw is attached to a wall of the beverage container, which is also brought in synchronously by a conveying device, by means of an intermittently actuated presser pressed, namely in an adhesive bed molded onto the wall of the beverage container in a previous station.

Beim industriellen Abfüllen und Abpacken von Getränkebehältern kommt es darauf an, je Zeiteinheit eine möglichst grosse Stückzahl Getränkebehälter durchzusetzen. Bei der bekannten Vorrichtung und der damit verwirklichten Arbeitsweise ist die Arbeitsgeschwindigkeit durch die je Zeiteinheit verwirklichbaren Taktzahlen des Messers zum Abtrennen der Trinkhalme vom Trinkhalmband und des Andrückers zum Andrücken der abgetrennten Trinkhalme an ein an der Wand der mit jeweils einem Trinkhalm auszurüstenden Getränkebehälter angespritztes Klebebett begrenzt.When filling and packaging beverage containers industrially, it is important to get the largest possible number of beverage containers per unit of time. In the known device and the method of operation realized therewith, the working speed is limited by the cycle numbers of the knife for separating the drinking straws from the drinking straw band and the pressing means for pressing the separated drinking straws onto a wall of the adhesive container to be equipped with a drinking straw.

Eine ganz ähnlicheVorrichtung ist auch aus der GB-A-2121 756 vorbekannt, bei der zwischen einander zugekehrten Trumlagen zweier gegensinnig umlaufender Riemen ein Trinkhalmband einer Schneidestation zugeführt und aufeinanderfolgend jeweils ein Trinkhalm vom Trinkhalmband abgetrennt wird. Der so abgetrennte Trinkhalm wird dann von einer schwenkbaren Anordnung erfasst und in Kontakt mit der Aussenwand eines von einer anderen Fördereinrichtung zugeführten Getränkebehälters gebracht, dessen mit dem Trinkhalm auszurüstende Aussenwand in einer vorhergehenden Station mit einem angespritzten Klebebett versehen worden war.A very similar device is also known from GB-A-2121 756, in which a straw band is fed to a cutting station between the facing strands of two oppositely rotating belts and a straw is successively separated from the straw band. The drinking straw separated in this way is then gripped by a pivotable arrangement and brought into contact with the outer wall of a beverage container supplied by another conveying device, the outer wall of which the straw to be equipped had been provided with a molded adhesive bed in a previous station.

Hinsichtlich des Zuführens eines Trinkhalmbandes zu einer Schneidstation und des Abtrennens jeweils eines Trinkhalmes vom Trinkhalmband unterscheiden sich die beiden vorbekannten Vorrichtungen im Prinzip nicht. Hinsichtlich der Einrichtung zum Aufnehmen eines vom Trinkhalmband abgetrennten Trinkhalms und zum Anbringen desselben an der Aussenwand eines Getränkebehälters besteht jedoch bei der Vorrichtung nach der letztgenannten Vorveröffentlichung insofern ein Unterschied gegenüber der Vorrichtung nach der DE-A-2 902 899, als ein komplizierter Schwenkmechanismus eingesetzt ist, der angesichts seines vielteiligen Aufbaues und seiner Verschwenkung zwischen zwei Endlagen eine nur begrenzte Arbeitsgeschwindigkeit der Vorrichtung zulässt, die hinter der Arbeitsgeschwindigkeit der erstgenannten Vorrichtung zurückbleibt.In principle, the two previously known devices do not differ with regard to feeding a drinking straw band to a cutting station and separating a drinking straw from the drinking straw band. With regard to the device for receiving a drinking straw separated from the drinking straw band and for attaching it to the outer wall of a beverage container, however, the device according to the latter prior publication differs from the device according to DE-A-2 902 899 in that a complicated pivoting mechanism is used , which, in view of its multi-part structure and its pivoting between two end positions, permits only a limited working speed of the device, which remains behind the working speed of the first-mentioned device.

Ausgehend von diesem Stande der Technik besteht die Aufgabe der vorliegenden Erfindung in der Schaffung einer gattungsgemässen Vorrichtung, mit der die als Trinkhalmband zugeführten, in Schutzhüllen eingeschlossenen Trinkhalme an gruppenweise zugeführten Getränkebehältern angeklebt werden können.Based on this prior art, the object of the present invention is to provide a generic device with which the drinking straws supplied as a drinking straw band and enclosed in protective sleeves can be glued to group-supplied beverage containers.

Diese Aufgabe ist nach dem Kennzeichen des Patentanspruchs 1 dadurch gelöst, dass die Einrichtung zum Zuführen des Trinkhalmbandes schrittweise derart antreibbar ist, dass bei jedem Vorschubschritt ein mehrere eingehüllte Trinkhalme in vorbestimmter Anzahl umfassender Abschnitt des Trinkhalmbandes in die Schneidstation eingeführt wird, dass die Schneidstation eine der Anzahl der Trinkhalme des jeweils schrittweise zugeführten Trinkhalmbandes entsprechende Anzahl taktgleich betätigbarer Messer aufweist, dass die Trinkhalmfördereinrichtung als Gegenhalter beim Schneiden und zum Zuführen der vom Trinkhalmband abgetrennten Trinkhalme eine entsprechende Anzahl von Mitnehmern mit je einer Halterung zur Aufnahme jeweils eines eingehüllten Trinkhalms besitzt, dass die Behälterfördereinrichtung schrittweise antreibbar ist und mitteis letzterer die mit Trinkhalmen auszurüstenden Getränkebehälter der Anklebestation chargenweise in einer der Anzahl der gleichzeitig vom Trinkhalmband abgetrennten Trinkhalme entsprechenden Anzahl nebeneinanderliegend zugeführt werden und dass die einzelnen Mitnehmer der Trinkhalmfördereinrichtung unter Veränderung ihrer gegenseitigen Abstände derart in die Anklebestation verfahrbar sind, dass in der Endlage jeder Mitnehmer über einem der in entsprechender Anzahl zugeführten Getränkebehälter steht.This object is achieved according to the characterizing part of patent claim 1 in that the device for feeding the drinking straw band can be driven step by step in such a way that with each feed step a section of the drinking straw band encompassing a predetermined number of drinking straws is introduced into the cutting station in that the cutting station is one of the The number of drinking straws of the drinking straw band fed step by step has a corresponding number of knives which can be actuated at the same time, so that the drinking straw conveying device, as a counter-holder during cutting and for feeding the drinking straws separated from the drinking straw band, has a corresponding number of drivers, each with a holder for receiving an enveloped drinking straw, that the container conveying device can be driven step by step and by means of the latter the batches of beverage containers to be equipped with drinking straws in batches in one of the number of Ts separated from the drinking straw band at the same time the corresponding number of straws are fed next to each other and that the individual drivers of the drinking straw conveyor device can be moved into the gluing station by changing their mutual distances such that in the end position each driver corresponds to one of the in the number of beverage containers supplied.

Aus der US-A 4210484 ist zwar schon eine Vorrichtung zum gruppenweisen Anbringen von Etiketten an jeweils in entsprechender Anzahl gruppenweise einer Etikettierstation zugeführte Packungen bekannt, aber diese vorbekannte Vorrichtung konnte keine Anregung für das gruppenweise Abtrennen von in Schutzhüllen verpackten Trinkhalmen von einem Trinkhalmband sowie deren Anbringung an Getränkebehälter geben.From US-A 4210484 a device for applying labels in groups to packs supplied in groups of a corresponding number in groups to a labeling station is already known, but this previously known device could give no suggestion for the group-wise separation of drinking straws packed in protective covers from a drinking straw band and their attachment give to beverage container.

So wird bei dieser vorbekannten Vorrichtung ein Trägerband mit in mehreren Reihen nebeneinander angeordneten Etiketten einer Vereinzelungsstation zugeführt und das Ablösen der Etiketten von dem Trägerband erfolgt durch dessen scharfkantige Umlenkung in einer Vereinzelungsstation, wobei die abgelösten Etiketten in der Vereinzelungsstation dann mittels Saugluft von Mitnehmern aufgenommen und diese Mitnehmer anschliessend in einer Richtung quer zur Zuführrichtung des Etiketten-Trägerbandes in Vereinzelungspositionen über mittels einer anderen Fördereinrichtung zugeführte Packungen verfahren, sowie durch Absenken der Mitnehmer jeweils ein Etikett an eine Packung angeklebt wird.In this known device, a carrier tape with labels arranged in several rows next to one another is fed to a singling station and the labels are detached from the carrier tape by its sharp-edged deflection in a singling station, the detached labels in the singling station then being taken up by entrained air by suction air and these are then taken up Then move the carrier in a direction transverse to the feed direction of the label carrier tape in separation positions over packs supplied by another conveying device, and a label is glued to a pack by lowering the carriers.

Während bei der vorbekannten Vorrichtung die Anzahl der jeweils gruppenweise vereinzelten Etiketten der Anzahl der nebeneinanderliegend auf einem Trägerband aufgenommenen Etikettenreihen entspricht, handelt es sich bei der Erfindung darum, dass von einem Trinkhalmband mit in Bandlängsrichtung aufeinanderfolgenden Schutzhüllen mit je einem eingehüllten Trinkhalm letztere in vorbestimmter Anzahl chargenweise in einer besonderen Schneidstation abgetrennt und dann den von einer Behälterfördereinrichtung zugeführten Getränkebehälters mittels spezieller Mitnehmer positionsgerecht zugeführt und an die Getränkebehälter angeklebt werden,wobei die Mitnehmer in der Schneidstation als Gegenhalter beim Abtrennen der einzelnen Trinkhalme von einem in entsprechender Länge zugeführten Abschnitt des Trinkhalmbandes dienen. Hierfür konnte die vorbekannte Vorrichtung keinerlei Anregung geben.While in the previously known device the number of individually grouped labels corresponds to the number of adjacent rows of labels received on a carrier tape, the invention is that of a drinking straw tape with successive protective sleeves in the longitudinal direction of the tape, each with an encased drinking straw, the latter in batches in a predetermined number separated in a special cutting station and then fed to the beverage containers supplied by a container conveyor by means of special drivers and glued to the beverage containers, the drivers in the cutting station serving as counterhold when the individual drinking straws are separated from a section of the drinking straw band that is supplied in a corresponding length. The previously known device could give no suggestion for this.

Zweckmässige Ausgestaltungen der erfindungsgemässen Vorrichtung sind in den nachgeordneten Patentansprüchen 2 bis 14 angegeben.Appropriate configurations of the device according to the invention are specified in the subordinate claims 2 to 14.

So sieht eine dieser Ausgestaltungen vor, dass bei der Verarbeitung eines Trinkhalmbandes mit einem in Bandlängsrichtung verlaufenden, durch ein Deckband abgedeckten Klebestreifen, vor der Schneidstation eine Abzieheinrichtung für das Deckband angeordnet ist.One of these configurations provides that when processing a drinking straw band with an adhesive strip running in the longitudinal direction of the band and covered by a cover band, a pulling device for the cover band is arranged in front of the cutting station.

Bei dieser Ausgestaltung entfällt das für die Arbeitsweise nach der DE-A-2 902 899 typische Anspritzen je eines Klebebettes an die mit Trinkhalmen auszurüstenden Wände der Getränkebehälter und es gelingt in einfacher Weise, zum Zwecke des Anklebens die vereinzelten und positionierten, in Schutzhüllen eingeschlossenen Trinkhalme unter leichtem Druck mit der Wand eines Getränkebehälters in Kontakt zu bringen, um dadurch die die Trinkhalme aufnehmenden Schutzhüllen an den Behälterwänden anzukleben. Naturgemäss erstreckt sich der mittels des Deckbandes abgedeckte Klebestreifen auf der beim Zuführen des Trinkhalmbandes zu den mittels der erwähnten Fördereinrichtung zur Anklebestation zugeführten Getränkebehältern hinweisenden Seite.In this embodiment, the spraying of an adhesive bed typical of the method according to DE-A-2 902 899 is omitted on the walls of the beverage containers to be equipped with drinking straws, and it is possible in a simple manner for the purpose of sticking on the isolated and positioned drinking straws enclosed in protective sleeves to bring it into contact with the wall of a beverage container under slight pressure, in order to thereby glue the protective sleeves holding the drinking straws to the container walls. Naturally, the adhesive strip covered by the cover tape extends on the side pointing toward the beverage containers fed to the adhesive station by means of the conveyor device mentioned when the drinking straw tape is fed in.

Eine andere zweckmässige Ausgestaltung der erfindungsgemässen Vorrichtung besteht darin, dass die Schneidstation eine zwischen der Schneidposition und einer zurückgezogenen Lage hin- und herbewegbare Messerplatte umfasst, auf der die Trennmesser fest aufgenommen sind und die unter den Mitnehmern, wenn diese in der Schneidstation stehen und als Gegenhalter beim Schneiden dienen, angeordnet ist, und dass die Trennmesser sich durch Führungen in einer über Federmittel elastisch nachgiebig an der Messerplatte abgestützten Vorhalteplatte hindurcherstrecken, die beim Schneiden gegen die dann in der Schneidstation stehenden Gegenhalter fährt und dabei das der Schneidstation zugeführte Trinkhalmband zwischen sich und den Mitnehmern aufnimmt, wobei die im übrigen gegenüber der Oberfläche der Vorhalteplatte in einer zurückgezogenen Stellung stehenden Messerschneiden nach oben aus der Vorhalteplatte austreten und die einzelnen Trinkhalmhüllen vom Trinkhalmband abtrennen.Another expedient embodiment of the device according to the invention is that the cutting station comprises a knife plate which can be moved back and forth between the cutting position and a retracted position, on which the separating knives are firmly received and which are located under the drivers when they are in the cutting station and as counterholders serve when cutting, is arranged, and that the separating knives extend through guides in a resiliently resiliently supported on the cutter plate by spring means, which moves during cutting against the counterholders then standing in the cutting station and thereby the drinking straw band fed to the cutting station between them and the Carriers takes up, the knife edges, which are otherwise in a retracted position opposite the surface of the retention plate, emerge upward from the retention plate and separate the individual straw covers from the drinking straw band.

Bei der Verwendung eines mit einem Klebestreifen ausgerüsteten Trinkhalmbandes, dessen Klebestreifen auf der zu der Fördereinrichtung zum Zuführen der Getränkebehälter zur Anklebestation hinweisenden Seite liegt, hat es sich als zweckmässig erwiesen, wenn sich in der Oberfläche der Vorhalteplatte eine nach Lage und Breite dem am Trinkhalmband angebrachten Klebestreifen entsprechende Längsnut in Zuführrichtung des Trinkhalmbandes erstreckt, so dass das Trinkhalmband nur beidseitig des im Bereich der Längsnut geführten Klebestreifens auf der Vorhalteplatte aufgenommen wird und Störungen durch ein unerwünschtes Ankleben des Klebestreifens an der Vorhalteplatte ausgeschlossen sind.When using a drinking straw band equipped with an adhesive strip, the adhesive strip of which lies on the side pointing towards the conveying device for feeding the beverage containers to the gluing station, it has proven to be expedient if the surface and width of the holding plate are attached to the drinking straw band according to their position and width Adhesive tape extends the corresponding longitudinal groove in the feed direction of the drinking straw tape, so that the drinking straw tape is only received on both sides of the adhesive tape guided in the area of the longitudinal groove on the retention plate and interference from undesired sticking of the adhesive tape to the retention plate is excluded.

Eine weitere vorteilhafte Ausgestaltung der erfindungsgemässen Vorrichtung besteht darin, dass in der Schneidstation unabhängig von der Betätigung der Trennmesser betätigbare Haltemittel zum Erfassen und Festhalten des Trinkhalmbandes, nachdem dieses der Schneidstation zugeführt ist, angeordnet sind. Bei diesen Haltemitteln kann es sich um wenigstens einen Stichel handeln, der einen der Trennmesser benachbart, jedoch diesem gegenüber in Zuführrichtung des Trinkhalmbandes versetzt so angeordnet ist, dass er in der Halteposition zwischen zwei benachbarten Trinkhalmhüllen formschlüssig in das Trinkhalmband eingreift. Dabei hat es sich als zweckmässig erwiesen, wenn der Stichel zum Erfassen und Festhalten desin der Schneidstation zugeführten Trinkhalmbandes in sich durch die Messerplatte und die Vorhalteplatte indurcherstrekkenden Führungen aufgenommen und mittels eines an der Messerplatte angeordneten Betätigungsgliedes, etwa eines Druckluftzylinders, zwischen einer über die Oberfläche der Vorhalteplatte hinausragenden und formschlüssig in das der Schneidstation zugeführte Trinkhalmband eingreifenden Stellung und einer demgegenüber zurückgezogenen Lage hin- und herbewegbar ist. Eine derartige Vorrichtungsausbildung ermöglicht ein sicheres Aufnehmen und Halten des der Schneidstation zugeführten Abschnittes des Trinkhalmbandes auf der Vorhalteplatte.A further advantageous embodiment of the device according to the invention consists of holding means which can be actuated, independently of the actuation of the separating knives, being arranged for gripping and holding the drinking straw band after it has been fed to the cutting station. These holding means can be at least one graver, which is arranged adjacent to one of the separating knives, but offset relative to the latter in the feed direction of the drinking straw band, so that it engages in the holding position between two adjacent drinking straw casings in a form-fitting manner in the drinking straw band. It has proven to be expedient if the stylus for grasping and holding the drinking straw band supplied in the cutting station is received in guides which extend through the knife plate and the holding plate and by means of an actuator arranged on the knife plate supply member, such as a compressed air cylinder, between a protruding beyond the surface of the retaining plate and positively engaging in the drinking straw band supplied to the cutting station and a position retracted relative to it can be moved back and forth. Such a device design enables the section of the drinking straw band supplied to the cutting station to be securely picked up and held on the holding plate.

Ein anderes wichtiges Ausgestaltungsmerkmal der erfindungsgemässen Vorrichtung besteht darin, dass die Einrichtung zum Zuführen des von der Vorratsrolle abziehbaren Trinkhalmbandes zur Schneidstation einen mit Mitteln zum Erfassen und Halten des in Zuführrichtung jeweils vorderen Endes des Trinkhalmbandes versehenen Vorschubblock besitzt, der aus einer in Zuführrichtung vor dem ersten Trennmesser der Schneidstation liegenden Anfangsstellung in eine Endlage über der Schneidstation und wieder zurück verfahrbar ist. Die Mittel zum Erfassen und Halten des in Zuführrichtung jeweils vorderen Endes des Trinkhalmbandes können eine am Vorschubblock etwa senkrecht zur Zuführrichtung bewegbar geführte Mitnehmerplatte umfassen, die mittels eines Betätigungsorgans, etwa eines Luftzylinders, beim Aufnehmen des Trinkhalmbandes in der Anfangsstellung des Vorschubblocks bzw. beim Übergeben des Trinkhalmbandes in der Schneidstation etwa senkrecht zur Zuführrichtung des Trinkhalmbandes betätigbar ist.Another important design feature of the device according to the invention is that the device for feeding the straw band that can be pulled off the supply roll to the cutting station has a feed block provided with means for grasping and holding the front end of the straw band in the feed direction, which consists of a feed block in front of the first in the feed direction Cutting knife of the cutting station is in the initial position in an end position above the cutting station and back again. The means for grasping and holding the front end of the drinking straw band in the feed direction can comprise a driver plate which is movably guided on the feed block approximately perpendicular to the feed direction and which, by means of an actuating member, for example an air cylinder, when the drinking straw band is picked up in the initial position of the feed block or when transferring the Drinking straw band can be actuated in the cutting station approximately perpendicular to the feed direction of the drinking straw band.

Eine gleichfalls weitere wichtige Ausgestaltung der erfindungsgemässen Vorrichtung besteht darin, dass die Mitnehmer zum Zuführen und Positionieren der vom Trinkhalmband abgetrennten Trinkhalme und die Mitnehmerplatte zum Zuführen des Trinkhalmbandes zur Schneidstation mit sich quer zur Zuführrichtung des Trinkhalmbandes erstreckenden Aufnahmenuten für jeweils einen Trinkhalm mit Schutzhülle versehen sind. Diese gewährleistet einerseits eine positionsgenaue Aufnahme der vom Trinkhalmband abgetrennten Trinkhalme in den genannten Aufnahmenuten der Mitnehmer und andererseits ein positionsgenaues Zuführen des Trinkhalmbandes zur Schneidstation.Another equally important embodiment of the device according to the invention is that the drivers for feeding and positioning the drinking straws separated from the drinking straw band and the driving plate for feeding the drinking straw band to the cutting station are provided with receiving grooves for a drinking straw each with a protective cover that extend transversely to the feeding direction of the drinking straw band. This ensures, on the one hand, that the drinking straws separated from the drinking straw band are picked up in the specified grooves in the catches and, on the other hand, that the drinking straw band is fed to the cutting station in a precisely positioned manner.

Obgleich im Rahmen der Erfindung verschiedene Mittel zum Erfassen und Halten des Trinkhalmbandes bzw. der von letzterem abgetrennten Trinkhalme in Betracht kommen können, sieht eine weitere Ausgestaltung vor, dieses Erfassen und Halten mittels Saugluft zu verwirklichen, die über Düsenbohrungen in den Mitnehmern und/ oder der Oberfläche der Vorhalteplatte am Trinkhalmband bzw. den von letzterem abgetrennten Trinkhalmen angreift.Although various means for grasping and holding the drinking straw band or the straws separated from the latter can be considered within the scope of the invention, a further embodiment provides for this gripping and holding to be realized by means of suction air, which via nozzle bores in the drivers and / or Attacks the surface of the retention plate on the drinking straw band or the drinking straws separated from the latter.

Nach einem anderen Ausgestaltungsmerkmal der Erfindung können der Vorschubblock zum Zuführen des Trinkhalmbandes zur Schneidstation und die Mitnehmer zum Zuführen und Positionieren der von dem Trinkhalmband abgetrennten Trinkhalme zur Anklebestation mittels miteinander fluchtender Führungen hin- und herbewegbar geführt und taktgleich in der Weise betätigt sein, dass während des Verfahrens der Mitnehmer mit den an diesen aufgenommenen, vom Trinkhalmband abgetrennten Trinkhalmen in die Anklebestation der Vorschubblock in die Schneidstation über den Trennmessern vorfährt und die vorbestimmte Anzahl Trinkhalme am vorderen Ende des Trinkhalmbandes der Schneidstation positionsgenau zuführt, hingegen korrespondierend zum Rücklauf der Mitnehmer aus der Anklebestation in die Schneidstation aus letzterer in seine Anfangslage zurückgelangt.According to another design feature of the invention, the feed block for feeding the drinking straw band to the cutting station and the drivers for feeding and positioning the drinking straws separated from the drinking straw band to the gluing station can be guided to and fro by means of guides that are aligned with one another and actuated in a timed manner in such a way that during the Moving the driver with the straws picked up from them and separated from the straw band into the gluing station of the feed block into the cutting station over the cutting knives and feeding the predetermined number of straws at the front end of the straw band to the cutting station, correspondingly to the return of the dogs from the gluing station in the cutting station from the latter returned to its initial position.

Eine weitere Ausgestaltung ist dadurch gekennzeichnet, dass die in der Schneidstation je einen vom Trinkhalmband abgetrennten Trinkhalm aufnehmenden Mitnehmer über der Fördereinrichtung zum Zuführen jeweils einer vorbestimmten Anzahl Getränkebehälter so geführt und angetrieben sind, dass die lagerichtige Positionierung der Mitnehmer über den in der Anklebestation stehenden Getränkebehältern erfolgt, indem diese Mitnehmer gegen in Abständen voneinander positionsgenau angeordnete Anschläge fahren und nach dem Ankleben der Trinkhalme an die Getränkebehälter aus der Anklebestation in die Schneidposition zurückgeführt werden, in der diese Mitnehmer in unmittelbar benachbarten Positionen über der Vorhalteplatte der Schneidstation stehen.A further embodiment is characterized in that the drivers receiving a straw separated from the drinking straw band in the cutting station are guided and driven above the conveyor for feeding a predetermined number of beverage containers in each case such that the drivers are positioned correctly over the beverage containers in the gluing station , by driving these drivers against stops which are arranged at exactly the same distance from one another and, after the drinking straws have been glued to the beverage containers, are returned from the gluing station to the cutting position, in which these drivers are in immediately adjacent positions above the holding plate of the cutting station.

Als zweckmässig hat sich auch erwiesen, wenn als Führungsmittel für die genannten Mitnehmer feste Längsführungen vorgesehen sind und wenn die chargenweise zugeführten Getränkebehälter in der Anklebestation von einer Hubeinrichtung zum Anheben und Andrücken der Getränkebehälter an die unterseitig mit Trinkhalmen bestückten Mitnehmer aufgenommen sind.It has also proven to be useful if fixed longitudinal guides are provided as guide means for the drivers mentioned and if the batch-supplied beverage containers are received in the gluing station by a lifting device for lifting and pressing the beverage containers onto the drivers equipped with drinking straws on the underside.

Bei der als Ausführungsbeispiel veranschaulichten Vorrichtung wird von einer in hier nicht weiter interessierender Weise bei 10 drehbar und austauschbar gelagerten Vorratsrolle 11 ein Trinkhalmband 12 abgezogen und über eine Umlenkrolle 13 und eine Zuführwalze 14, wie unten noch näher erläutert wird, abschnittsweise einer Schneidstation 15 der Vorrichtung zugeführt. Das von der Vorratsrolle 11 abziehbare Trinkhalmband 12 besteht aus aneinandergefügten Schutzhüllen mit je einem quer zur Bandlängserstreckung in Parallellage zueinander und in untereinander gleichen Abständen angeordneten Trinkhalm. Das Trinkhalmband 12 ist auf derjenigen Seite, die in der Schneidstation 15 nach unten weist, mit einem etwa in der Mitte seiner Breitenerstreckung durchlaufenden Klebestreifen versehen, der auf der Vorratsrolle 11 mittels eines Abdeckstreifens abgedeckt ist. Dieser Abdeckstreifen 16 wird beim Abziehen des Trinkhalmbandes von der Vorratsrolle 11 über die in Fig. 1 angedeutete Umlenkrolle 17 mittels der ebenfalls angedeuteten Haspel 18 abgezogen und aufgewickelt, so dass der Klebestreifen des zu der Vorrichtung zugeführten Trinkhalmbandes freigelegt ist.In the device illustrated as an exemplary embodiment, a drinking straw band 12 is pulled off a supply roll 11 which is rotatably and exchangeably mounted at 10 in a manner of no further interest here, and sectionally a cutting station 15 of the device via a deflection roll 13 and a feed roller 14, as will be explained in more detail below fed. The drinking straw band 12 which can be pulled off the supply roll 11 consists of joined protective sleeves, each with a drinking straw arranged parallel to one another and at equal intervals to one another transversely to the longitudinal direction of the band. The drinking straw band 12 is provided on the side which points downward in the cutting station 15 with an adhesive strip which extends approximately in the middle of its width and which is covered on the supply roll 11 by means of a cover strip. This cover strip 16 is pulled off and wound up when the drinking straw band is removed from the supply roll 11 via the deflection roller 17 indicated in FIG. 1 by means of the reel 18 also indicated, so that the adhesive strip of the drinking straw band fed to the device is exposed.

Die in nicht weiter interessierender Weise im Vorrichtungsgestell drehbar gelagerte Zuführwalze 14 besitzt sich in Parallellage zur Walzendrehachse im Walzenmantel erstreckende und im Teilungsmass der Trinkhalme des Trinkhalmbandes 12 angeordnete Längsausnehmungen, in welche die einzelnen, in Schutzhüllen aufgenommenen Trinkhalme des Bandes beim Zuführen zur Schneidstation 15 eingreifen. Als Mittel zum Zuführen des Trinkhalmbandes zu der Schneidstation steht ein zwischen der Zuführwalze 14 und der Schneidstation 15 angeordneter, zwischen einer Anfangslage und der Schneidstation hin- und herbewegbar geführter Vorschubblock 20, der unterseitig mit einer um ein begrenztes Mass vertikal bewegbaren Mitnehmerplatte 21 versehen ist. Diese Mitnehmerplatte ist unterseitig mit gleichfalls im Teilungsmass der Trinkhalme des Trinkhalmbandes 12 angeordneten, sich quer zur Zuführrichtung erstreckender Aufnahmenuten 22 versehen und mittels eines Arbeitszylinders 23 aus der in den Fig. 2 und 3 in der Anfangsstellung ersichtlichen Lage auf das über eine nicht weiter dargestellte untere Führung zugeführte Trinkhalmband 12 so absenkbar, dass die Aufnahmenuten 23 jeweils eine der angedeuteten Schutzhüllen 24 mit Trinkhalm übergreifen. Im Bereich dieser Aufnahmenuten 22 münden nicht gezeigte Saugdüsen aus, die in ebenfalls nicht dargestellter Weise mit Saugluft beaufschlagbar sind und ein Ansaugen und damit Festhalten des übergriffenen Abschnittes des Trinkhalmbandes 12 ermöglichen.The feed roller 14, which is rotatably mounted in the device frame in a manner of no further interest, has longitudinal recesses, which extend parallel to the axis of rotation of the roller in the roller shell and are arranged at the pitch of the drinking straws of the drinking straw band 12, into which the individual drinking straws of the band which are accommodated in protective sleeves engage when they are fed to the cutting station 15. A means for feeding the drinking straw band to the cutting station is a feed block 20 which is arranged between the feed roller 14 and the cutting station 15 and can be moved back and forth between an initial position and the cutting station and is provided on the underside with a driver plate 21 which can be moved vertically to a limited extent. This driver plate is provided on the underside with also arranged in the pitch of the drinking straws of the drinking straw band 12, transverse to the feed direction receiving grooves 22 and by means of a working cylinder 23 from the position shown in FIGS. 2 and 3 in the initial position to a lower, not shown Guide fed drinking straw band 12 so that the receiving grooves 23 each overlap one of the indicated protective covers 24 with a drinking straw. In the area of these receiving grooves 22, suction nozzles (not shown) open out, which can also be acted upon with suction air in a manner not shown and which allow suction and thus holding of the overlapped portion of the drinking straw band 12.

Das so erfasste, in Zuführrichtung vordere Ende des Trinkhalmbandes 12 wird dann aus der in den Fig. 2 und 3 ersichtlichen Anfangsstellung des Vorschubblocks 20 durch dessen Verfahren in die aus Fig. 1 ersichtliche Lage in der Schneidstation 15 letzterer lagerichtig auf einer Vorhalteplatte 26 zugeführt und dort durch Betätigung eines Stichels 27 fest gehalten, der in einer sich durch eine Messerplatte 28 und die Vorhalteplatte 26 vertikal hindurcherstreckenden Führung aufgenommen und mittels eines Betätigungszylinders 29 in eine Haltelage über die Oberfläche 30 der Vorhalteplatte betätigbar ist, wobei der Stichel im Bereich eines Verbindungsstücks zwischen zwei benachbarten Schutzhüllen 24 formschlüssig in das Trinkhalmband eingreift.The end of the drinking straw band 12 which is detected in the feed direction in this way is then fed from the initial position of the feed block 20 shown in FIGS. 2 and 3 by its method into the position shown in FIG. 1 in the cutting station 15 of the latter in the correct position on a holding plate 26 and held there by actuation of a stylus 27, which is received in a guide extending vertically through a knife plate 28 and the holding plate 26 and can be actuated by means of an actuating cylinder 29 into a holding position over the surface 30 of the holding plate, the stylus in the region of a connecting piece between two adjacent protective sleeves 24 engage positively in the drinking straw band.

Während des Zuführens des jeweils in Bandzuführrichtung vorn liegenden Endes des Trinkhalmbandes 12 zur Schneidstation 15 befinden sich mehrere in Zuführrichtung aufeinanderfolgend angeordnete Mitnehmer 32 bis 36 in den aus den Fig. 1 und 4 ersichtlichen Vereinzelungspositionen in einer Anklebestation 38 und stehen lagerichtig über nebeneinanderliegend in einerr nach oben offenen Verpackungsbehälter 40 aufgenommenen Getränkebeuteln 41. Nachdem das mittels desVorschubblocks 20 der Schneidstation 15 zugeführte Trinkhalmband in der aus den Fig, 2 und 3 ersichtlichen Weise auf der Oberfläche 3C der Vorhalteplatte 26 aufgenommen und mittels des formschlüssig zwischen zwei benachbarten Schutzhüllen 24 in das Trinkhalmband eingreifenden Stichels 27 lagerichtig festgehalten ist, wird die Saugluftbeaufschlagung der Aufnahmenuten 22 aufgehoben und die Mitnehmerplatte 21 des Vorschubblocks infolge Betätigung durch den genannten Arbeitszylinder 23 aus der Transportlage in die in der Zeichnung dargestellte erhöhte Position angehoben. Anschliessend fährt der Vorschubblock 20 längs seiner Führung aus der Schneidstation in die Anfangsstellung nach den Fig. 2 und 3 zurück.During the feeding of the end of the drinking straw band 12, which is at the front in the band feeding direction, to the cutting station 15, a plurality of drivers 32 to 36, arranged successively in the feeding direction, are located in the singling positions shown in FIGS. 1 and 4 in an adhesive station 38 and are in the correct position above one another in a row Beverage bags 41 received at the top of the open packaging container 40. After the drinking straw band fed to the cutting station 15 by means of the feed block 20 has been received in the manner shown in FIGS. 2 and 3 on the surface 3C of the retaining plate 26 and has a form-fitting engagement between two adjacent protective sleeves 24 in the drinking straw band Graver 27 is held in the correct position, the suction air application of the receiving grooves 22 is canceled and the driver plate 21 of the feed block as a result of actuation by the aforementioned working cylinder 23 from the transport position into that shown in the drawing set raised position raised. The feed block 20 then moves back along its guidance from the cutting station into the starting position according to FIGS. 2 and 3.

Korrespondierend zu der Rücklaufbewegung des Vorschubblocks 20 aus der Schneidstation 15 in die Anfangsstellung nach Fig. 1 fahren die Mitnehmer 32 bis 36 aus ihren Vereinzelungspositionen in der Anklebestation 38 in die in den Fig. 2 und 3 veranschaulichte Betriebsstellung in die Schneidstation, in der je ein Mitnehmer, die unterseitig mit ähnlich ausgebildeten Aufnahmenuten 42 wie die Mitnehmerplatte 21 des Vorschubblocks 20 ausgerüstet sind, lagerichtig über je einer der Schutzhüllen 24 des auf der Vorhalteplatte 26 aufgenommenen Abschnittes des Trinkhalmbandes steht. Im Bereich der unterseitigen Aufnahmenuten dieser Mitnehmer münden ebenfalls nicht gezeigte Saugluftdüsen aus, die in nich1 dargestellter Weise mit Saugluftanschlüssen in Verbindung stehen und mit Saugluft beaufschlagbar sind.Corresponding to the return movement of the feed block 20 from the cutting station 15 into the initial position according to FIG. 1, the drivers 32 to 36 move from their singling positions in the gluing station 38 into the operating position illustrated in FIGS. 2 and 3 into the cutting station, in each case Carriers, which are equipped on the underside with receiving grooves 42 of similar design as the driving plate 21 of the feed block 20, are positioned correctly over one of the protective sleeves 24 of the section of the drinking straw band accommodated on the holding plate 26. In the area of the receiving grooves on the underside of these drivers, suction air nozzles (not shown) also open, which are connected to suction air connections in a manner not shown and can be acted upon by suction air.

In der Oberfläche 30 der Vorhalteplatte 26 erstrecken sich ebenso wie in den Führungsmittelr zwischen der Zuführwalze 14 und der Schneidstation nach Lage und Breite dem unterseitig arr Trinkhalmband angeordneten Klebestreifen entsprechende, nichtgezeigte Längsausnehmungen Desgleichen sind die Umlenkrolle 13 und der Zuführwalze 14 zugeordnete, diese auf einem Teilbereich ihres Umfanges mit Abstand umschliessende Führungsmittel 44 im Bereich des freiliegenden Klebestreifens mit Aussparungen versehen und greifen nur beidseitig des genannten Klebestreifens am Trinkhalmband 12 an.In the surface 30 of the holding plate 26, as well as in the guide means between the feed roller 14 and the cutting station, according to position and width, the adhesive strips arranged on the underside of the drinking straw band correspond to longitudinal recesses, not shown. Likewise, the deflecting roller 13 and the zu Guide roller 14 assigned, which surround these on a partial area of their circumference by a distance in the area of the exposed adhesive strip with recesses and engage only on both sides of the said adhesive strip on the drinking straw band 12.

Die bereits erwähnte Vorhalteplatte 26 der Schneidstation 15 ist auf einer unter der Vorhalteplatte und im Abstand von dieser angeordneten Messerplatte 28 aufgenommen und letzterer gegenüber durch Federmittel 46 elastisch abgestützt. In Zuführrichtung des Trinkhalmbandes sind in Abständen voneinander, die dem Teilungsmass der Schutzhüllen 24 des Trinkhalmbandes 12 entsprechen, auf dieser Messerplatte mehrere Trennmesser 48 fest angeordnet, die sich durch Führungen in der Vorhalteplatte hindurcherstrecken und deren Messerschneiden beim Zuführen des Trinkhalmbandes unter der Oberfläche 30 der Vorhalteplatte 26 stehen. Die Messerplatte steht über in Fig. 1 nur angedeutete Zugstangen 49 mit einer über der Schneidstation angeordneten Betätigungsplatte 50 in fester Verbindung. Diese Betätigungsplatte 50 ist über einen Lenker 52 von einem in hier nicht weiter interessierender Weise motorisch angetriebenen Exzenter 53 im Oberteil der Vorrichtung vertikal betätigbar. Angesichts der festen Verbindung der Betätigungsplatte 50 mit der Messerplatte 28 führt eine derartige Betätigung zu einem Anheben der Messerplatte mit der darüber aufgenommenen Vorhalteplatte 26 und dem auf letzterer aufgenommenen Abschnitt des Trinkhalmbandes, bis unter Zwischenlage des Trinkhalmbandes die Vorhalteplatte gegen die Unterseiten der beim Schneidvorgang in der Schneidstation 15 stehenden und beim Schneiden als Gegenhalter dienenden Mitnehmer 32 bis 36 gedrückt wird, wobei einerseits die nebeneinanderliegenden Schutzhüllen 24 des Trinkhalmbandes mit je einem Trinkhalm in den unterseitigen Aufnahmen 42 der Gegenhalter aufgenommen und durch Saugluft-Beaufschlagung festgehalten und andererseits die Trennmesser 48 infolge Zusammendrückung der die Vorhalteplatte abstützenden Federmittel 46 mit ihren Schneiden über die Oberfläche der Vorhalteplatte hinaus und in entsprechende Aussparungen 54 zwischen den einzelnen Mitnehmern hineinfahren. Dadurch werden die Verbindungsabschnitte zwischen benachbarten Schutzhüllen 24 des in der Schneidstation aufgenommenen Abschnittes des Trinkhalmbandes 12 durchtrennt und mithin eine der Anzahl der Messer entsprechende Anzahl Schutzhüllen 24 von dem der Schneidstation zugeführten Abschnitt des Trinkhalmbandes abgetrennt. Beim Weiterlauf des den Antrieb der Messerplatte 28 vermittelnden Exzenters 53 fährt die Messerplatte mit der darauf aufgenommenen Vorhalteplatte in die aus den Fig. 2 und 3 ersichtliche Lage zurück, wobei die Vorhalteplatte 26 unter der Wirkung der zwischen dieser und der Messerplatte angeordneten Federmittel 46 in ihre Ausgangslage gelangt, so dass die Schneiden der Trennmesser 48 wieder unter der Oberfläche 30 der Vorhalteplatte stehen. Infolge einer entsprechenden Betätigung des mit dem Stichel 27 in Verbindung stehenden Arbeitszylinders 29, der unterseitig an der Messerplatte angeordnet ist, wird der Stichel gleichfalls in eine gegenüber der Oberfläche der Vorhalteplatte abgesenkten Lage zurückgezogen.The aforementioned holding plate 26 of the cutting station 15 is received on a knife plate 28 arranged below and at a distance from the holding plate and is elastically supported by spring means 46. In the feed direction of the drinking straw band, at a distance from one another, which correspond to the pitch of the protective sleeves 24 of the drinking straw band 12, a plurality of separating knives 48 are fixedly arranged, which extend through guides in the holding plate and whose knife edges when the drinking straw band is fed under the surface 30 of the holding plate 26 stand. The knife plate is in a fixed connection via pull rods 49, which are only indicated in FIG. 1, with an actuating plate 50 arranged above the cutting station. This actuating plate 50 can be actuated vertically via a link 52 by an eccentric 53 which is motor-driven in the upper part of the device and is of no further interest here. In view of the fixed connection of the actuating plate 50 with the knife plate 28, such actuation leads to a lifting of the knife plate with the holding plate 26 received thereon and the portion of the drinking straw band accommodated on the latter until the holding plate against the undersides of the during the cutting process is interposed with the drinking straw band Cutting station 15 standing and serving as a counterholder driver 32 to 36 is pressed, on the one hand the side by side protective sleeves 24 of the drinking straw band with a drinking straw in the underside receptacles 42 of the counterholders and held by suction air and on the other hand the cutting knife 48 due to compression of the the spring means 46 supporting the retention plate with their cutting edges extend beyond the surface of the retention plate and into corresponding recesses 54 between the individual drivers. As a result, the connecting sections between adjacent protective sleeves 24 of the section of the drinking straw band 12 accommodated in the cutting station are severed, and consequently a number of protective sleeves 24 corresponding to the number of knives is separated from the section of the drinking straw band fed to the cutting station. As the eccentric 53, which drives the knife plate 28, continues to move, the knife plate with the reserve plate received thereon moves back into the position shown in FIGS. 2 and 3, the reserve plate 26 in its action under the action of the spring means 46 arranged between the latter and the knife plate Starting position comes, so that the cutting of the cutting knife 48 are again under the surface 30 of the reserve plate. As a result of a corresponding actuation of the working cylinder 29 which is connected to the stylus 27 and which is arranged on the underside of the cutter plate, the stylus is likewise withdrawn into a position which is lowered relative to the surface of the holding plate.

Wie insbesondere aus Fig. 3 ersichtlich ist, ist der Stichel 27 in Parallellage zu dem in Zuführrichtung vorn liegenden Trennmesser 48 der Schneideinrichtung 15 geführt. Zweckmässigerweise sind zwei synchron betätigte Stichel vorzusehen, die in der Nähe der seitlichen Ränder des Trinkhalmbandes angreifen.As can be seen in particular from FIG. 3, the stylus 27 is guided in a parallel position to the cutting knife 48 of the cutting device 15, which is at the front in the feed direction. It is expedient to provide two synchronously actuated gravers which act in the vicinity of the lateral edges of the drinking straw band.

Die in der oben erläuterten Weise in der Schneidstation 15 vom Trinkhalmband 12 in vorbestimmter Anzahl abgetrennten Schutzhüllen 24 mit Trinkhalmen sind, wie bereits erläutert, in den unterseitigen Aufnahmen 42 der Mitnehmer 32 bis 36 vermittels Saugluft gehalten. Nach dem Schneidvorgang verfahren die an Längsführungen, die sich in Zuführrichtung des Trinkhalmbandes erstrecken, verfahrbaren Mitnehmer 32 bis 36 in die aus den Fig. 1 und 4 ersichtlichen Vereinzelungspositionen 32' bis 36' in eine Anklebestation 38, der in im einzelnen hier nicht interessierender Weise taktgleich ein nach oben offener Verpackungsbehälter 40 mit nebeneinanderliegend in vorbestimmten Zuordnungslagen angeordneten Getränkebeuteln 41 zugeführt ist. Positioniert sind die jeweiligen Endlagen der Mitnehmer 32 bis 36 durch Endanschläge. Sobald die aus den Fig. 1 und 4 ersichtlichen Vereinzelungspositionen 32' bis 36' in der Anklebestation 38 erreicht sind, wird der die Getränkebeutel 41 in vorbestimmten Zuordnungslagen aufnehmende, nach oben offene Verpackungsbehälter 40 mittels einer nicht weiter dargestellten Einrichtung gemäss Pfeil 56 angehoben, so dass die nach oben weisenden Seiten der Getränkebeutel an die unterseitig an den Mitnehmern aufgenommenen Schutzhüllen 24 angedrückt und letztere vermittels der an den Schützhüllen angebrachten, nach unten weisenden Klebestreifen an den Getränkebeuteln angeklebt werden. Gleichzeitig wird die Saugluft-Beaufschlagung der unterseitigen Aufnahmen 42 der Mitnehmer 32 bis 36 unterbrochen, wodurch die Schutzhüllen freigegeben und im nunmehr an die Getränkebeutel angeklebten Zustand zusammen mit den in dem Verpackungsbehälter 40 aufgenommenen Getränkebeuteln abgesenkt und dann in hier nicht weiter interessierender Weise aus der Anklebestation 38 abgefördert werden.The protective covers 24 with drinking straws separated from the drinking straw band 12 in the predetermined manner in the cutting station 15 in the above-explained manner are, as already explained, held in the receptacles 42 on the underside 42 by means of suction air. After the cutting process, the drivers 32 to 36, which can be moved on longitudinal guides which extend in the feed direction of the drinking straw band, move into the separating positions 32 'to 36' shown in FIGS. 1 and 4 into a gluing station 38, which is of no particular interest here an upwardly open packaging container 40 with beverage bags 41 arranged next to one another in predetermined allocation positions is fed in synchronously. The respective end positions of the drivers 32 to 36 are positioned by end stops. As soon as the separating positions 32 'to 36' shown in FIGS. 1 and 4 'have been reached in the gluing station 38, the upwardly open packaging container 40 which receives the beverage bags 41 in predetermined correspondence positions is lifted by means of a device (not shown) according to arrow 56, so that the upward-facing sides of the beverage bags are pressed against the protective sleeves 24 received on the underside of the carriers and the latter are glued to the beverage bags by means of the downward-facing adhesive strips attached to the protective sleeves. At the same time, the suction air supply to the underside receptacles 42 of the drivers 32 to 36 is interrupted, as a result of which the protective sleeves are released and, in the state now adhered to the beverage bags, are lowered together with the beverage bags accommodated in the packaging container 40 and then in a manner of no further interest from the gluing station 38 are promoted.

Wie Fig. 4 zeigt, können im Parallelbetrieb zueinander auch zwei Trinkhalmbänder gleichzeitig und dementsprechend nebeneinanderliegend zwei Verpackungsbehälter mit in bestimmten Zuordnungslagen aufgenommenen Getränkebeuteln zugeführt werden. Demgemäss sind auch der Vorschubblock 20 und die Mitnehmer 32 bis 36 zum Aufnehmen und Vereinzeln der vom den Trinkhalmbändern abgetrennten Schutzhüllen für einen derartigen Parallelbetrieb ausgelegt. Bei der aus Fig. 4 ersichtlichen Vorrichtung dienen als Verpackungsbehälter schalenförmige Klapp-Pakkungen, in deren einer Hälfte die Getränkebeutel in der aus Fig. 1 ersichtlichen Lage aufgenommen sind, hingegen in der anderen Hälfte spiegelbildlich dazu. Dies bedingt die versetzte Anordnung der den beiden Hälften der Vorrichtung zugeordneten Mitnehmer in Zuführrichtung. Im übrigen unterscheidet sich eine für den vorerwähnten Parattetbetrieb ausgelegte Vorrichtung von der oben erläuterten Vorrichtung nicht.As shown in FIG. 4, two drinking straw bands can be fed simultaneously and accordingly lying next to each other, two packaging containers with beverage bags accommodated in specific positions in parallel operation. Accordingly, the feed block 20 and the drivers 32 to 36 are designed for receiving and separating the protective covers separated from the straw straps for such parallel operation. In the device shown in FIG. 4, cup-shaped folding packs serve as packaging containers kungen, in one half of which the beverage bags are accommodated in the position shown in FIG. 1, on the other hand, in mirror image. This requires the staggered arrangement of the drivers assigned to the two halves of the device in the feed direction. Otherwise, a device designed for the above-mentioned parat operation does not differ from the device explained above.

Der Vorteil gegenüber herkömmlichen Vorrichtungen zum Ankleben von in Schutzhüllen aufgenommenen Trinkhalmen an Getränkebehältern besteht darin, dass erfindungsgemäss jeweils eine vorbestimmte Anzahl Schutzhüllen mit Trinkhalmen gleichzeitig vom Trinkhalmband abgetrennt und gleichzeitig an einer entsprechenden Anzahl Getränkebeuteln, der Zuführung zu der Anklebestation ebenfalls chargenweise erfolgt, angeklebt werden. Dies ermöglicht einerseits eine beträchtliche Leistungssteigerung gegenüber dem aufeinanderfolgenden Ankleben einzelner Schutzhüllen mit Trinkhalmen an jeweils einzelne Getränkebeutel und andererseits trotz dieser Leistungssteigerung einen vergleichsweisen ruhigen Lauf der Vorrichtung, was naturgemäss verschleissmindernd und mithin zu weniger Störungen als beim Stande der Technik führt.The advantage over conventional devices for adhering drinking straws contained in protective sleeves to beverage containers is that, according to the invention, a predetermined number of protective sleeves with drinking straws are simultaneously separated from the drinking straw band and, at the same time, adhered to a corresponding number of beverage bags, which are also supplied in batches to the adhesive station. On the one hand, this enables a considerable increase in performance compared to the successive adhesion of individual protective sleeves with drinking straws to individual beverage bags, and on the other hand, despite this increase in performance, the device runs comparatively smoothly, which naturally reduces wear and therefore leads to fewer malfunctions than in the prior art.
