Description

Eine derartige Vorrichtung ist aus der DE 3800431 C2 bekannt.Such a device is known from DE 3800431 C2 known.

Die Erfindung betrifft eine Vorrichtung zum längsaxialen Führen von stabförmigen Produkten der Tabak verarbeitenden Industrie mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a device for longitudinal axial guidance of rod-shaped products of the tobacco-processing industry with the features of the preamble of claim 1.

Stabförmige Produkte der Tabak verarbeitenden Industrie sind z.B. Zigaretten, Zigarillos, Filter oder dergleichen, welche in einem Endlosstrang oder mehreren parallelen Endlossträngen in einer Strangmaschine hergestellt werden. In der Strangherstellmaschine wird der Endlosstrang durch einen auf ein angetriebenes Formatband aufgelegten Umhüllungsstreifen und einen darauf aufgelegten Strang von losen Tabakfasern oder Filtermaterialfasern hergestellt, wobei der Umhüllungsstreifen an einem Rand mit einer Leimspur versehen wird, anschließend in einem Formatabschnitt um den losen Strang der Tabakfasern oder der Filtermaterialfasern herumgelegt und an den Rändern schließlich verklebt wird. Der an den Rändern verklebte Umhüllungsstreifen fixiert den Endlosstrang mit einem vorgegebenen Durchmesser und einer vorgegebenen Dichte der Tabak- oder Filtermaterialfasern. Während dieses Herstellungsprozesses liegt bzw. liegen der Endlosstrang bzw. die Endlosstränge auf einem oder mehreren angetriebenen Formatbändern auf. Nachdem der Endlosstrang fertig hergestellt ist, werden von dem Endlosstrang mittels einer Schneideinrichtung Produkte mit einer vorbestimmten Länge abgeschnitten, welche auf einer Vorrichtung zum längsaxialen Führen einem Längsaxialförderer, wie z.B. einer Spinne, zugeführt und während der weiteren Transportbewegung von einem Queraxialförderer übernommen werden. Die Schneideinrichtung umfasst einen rotierenden Messerträger mit wenigstens einem radial vorstehenden Messer und ein Gegenlager in Form einer Schneidtube oder einem Tubenrad mit mehreren tubenförmigen Gegenlagern, durch welche der Strang während der Schnittbewegung unterstützt wird. Nach dem Schnittvorgang werden die abgetrennten Produkte auf der Vorrichtung zum längsaxialen Führen dem Längsaxialförderer lose aneinander anliegend zugeführt. Dabei werden die Produkte auf der Vorrichtung nicht aktiv transportiert, sondern allein aufgrund der Antriebsbewegung des Endlosstranges weitergeschoben.Bar-shaped products of the tobacco processing industry are, for example, cigarettes, cigarillos, filters or the like, which are produced in a continuous strand or several parallel endless strands in a stranding machine. In the strand making machine, the endless strand is produced by a wrapping strip applied to a driven format strip and a strand of loose tobacco fibers or filter material fibers laid thereon, wherein the wrapping strip is provided with a glue trace at one edge, then in a format section around the loose strand of tobacco fibers or Filter material fibers laid around and finally glued at the edges. The wrapping strip adhered to the edges fixes the endless strand with a predetermined diameter and density of the tobacco or filter material fibers. During this manufacturing process, the endless strand or the endless strands lie on one or more driven format strips. After the endless strand is finished, products are cut from the endless strand by means of a cutter with a predetermined length, which are fed on a device for longitudinal axial guidance of a Längsaxialförderer, such as a spider, and taken over during the further transport movement of a Queraxialförderer. The cutting device comprises a rotating knife carrier with at least one radially projecting knife and an abutment in the form of a cutting tube or a tube wheel with a plurality of tube-shaped abutments, by which the strand is supported during the cutting movement. After the cutting operation, the separated products are fed loosely against each other on the longitudinal axial guide device to the longitudinal axial conveyor. The products are not actively transported on the device, but pushed on solely because of the drive movement of the endless strand.

Ein grundsätzlich zu lösendes Problem dabei ist, dass die Produkte nach dem Verlassen der Schneideinrichtung bei einem Aufstauen auf der Vorrichtung zum längsaxialen Führen nach oben oder seitlich weggedrängt werden können, so dass die Produkte nicht mehr so geführt werden, wie dies eine einwandfreie Zuführung der Produkte zu dem Längsaxialförderer erfordern würde.A problem to be solved in principle is that after leaving the cutting device, the products can be pushed upwards or laterally in the event of damming on the device for longitudinal axial guidance, so that the products are no longer guided in the same way as a perfect supply of the products would require to the longitudinal axial conveyor.

Zur Vermeidung dieses Problems ist es bekannt, in der Vorrichtung eine Führungsschiene, welche auch als Prismenschiene bezeichnet wird, vorzusehen, in welcher Öffnungen kleiner Druckluftkanäle vorgesehen sind, über die in der Führungsschiene ein Unterdruck zum Halten der Produkte erzeugt werden kann. Für den Fall, dass die Produkte vorgegebenen Qualitätskriterien nicht entsprechen, können die Produkte ferner durch Beaufschlagen der Druckluftkanäle mit Überdruck aus der Führungsschiene ausgeblasen werden.To avoid this problem, it is known to provide in the device a guide rail, which is also referred to as a prism rail, are provided in which openings small compressed air channels through which a negative pressure for holding the products can be generated in the guide rail. In the event that the products do not meet given quality criteria, the products can also be blown out by applying the compressed air channels with pressure from the guide rail.

Ferner ist es aus der DE 38 00 431 C2 bekannt, ein Stabilisierungselement vorzusehen, welches in einem Bereich ausschließlich vor Beginn der Führung und in einer oberhalb der Führungsschiene liegenden Ebene angeordnet ist, und der Tendenz des Abhebens der Produkte entgegenwirkt.Furthermore, it is from the DE 38 00 431 C2 known to provide a stabilizing element, which in an area exclusively before the start of the guide and in an above the guide rail lying level, and counteracts the tendency of the lifting of the products.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine hinsichtlich der Führung der Produkte weiter verbesserte Vorrichtung zum längsaxialen Führen von stabförmigen Produkten der Tabak verarbeitenden Industrie bereitzustellen, die bei einem Formatwechsel einfacher auf das neue Format anpassbar sein soll.Against this background, the invention has for its object to provide a further improved in terms of leadership of products device for longitudinal axial guidance of rod-shaped products of the tobacco industry, which should be easier to adapt to the new format in a format change.

Zur Lösung der Aufgabe wird erfindungsgemäß eine Vorrichtung mit den Merkmalen des Anspruchs 1 vorgeschlagen. Weitere bevorzugte Weiterentwicklungen sind den Unteransprüchen zu entnehmen.To achieve the object, a device with the features of claim 1 is proposed according to the invention. Further preferred developments can be found in the dependent claims.

Gemäß dem Grundgedanken der Erfindung wird vorgeschlagen, dass in der Führungsschiene und in dem Führungsteil jeweils zwei in einem Winkel zueinander angeordnete und in Längsrichtung der Führungsschiene und/oder des Führungsteils verlaufende Führungsflächen vorgesehen sind, welche derart an dem Führungsteil und der Führungsschiene positioniert sind, dass sie sich zu einem Führungskanal ergänzen, und dass wenigstens zwei der Führungsflächen zueinander abstandsverstellbar ausgebildet sind. Durch die erfindungsgemäße Lösung ergibt sich eine erheblich verbesserte Führung der Produkte nach dem Abtrennen von dem Strang, indem ein Führungskanal geschaffen wird, in dem die Produkte zu allen Seiten hin geführt werden. Der Führungskanal ist dabei als ein länglicher Kanal mit einer Länge von wenigstens der Länge eines der abgetrennten Produkte, so dass die Produkte beim Durchlaufen durch den Führungskanal in wenigstens einer Stellung über ihre gesamte Länge an den Führungsflächen des Führungskanals anliegen und dadurch vorausgerichtet werden. Durch die in einem Winkel zueinander stehenden Führungsflächen und die Abstandsverstellung ist es darüber hinaus möglich, Produkte mit einem unterschiedlichen Durchmesser in dem Führungskanal an den Führungsflächen zu führen, da die im Querschnitt des Führungskanals punktförmigen Anlagelinien an den Führungsflächen durch die Abstandsverstellung auseinander oder aufeinander zu auf einen größeren oder einen kleineren Durchmesser bewegt werden können, welcher dem Durchmesser der Produkte nach dem Formatwechsel entspricht.According to the basic idea of the invention, it is proposed that in each case two guide surfaces which are arranged at an angle to one another and extend in the longitudinal direction of the guide rail and / or the guide part are provided in the guide rail and in the guide part, which are positioned on the guide part and the guide rail they complement each other to a guide channel, and that at least two of the guide surfaces are formed to each other adjustable in distance. The inventive solution results in a significantly improved management of the products after separation from the strand by a guide channel is created in which the products are guided to all sides. The guide channel is in this case as an elongate channel with a length of at least the length of one of the separated products, so that the products abut the guide surfaces of the guide channel in at least one position over at least one position when passing through the guide channel and are thereby precalibrated. By standing at an angle to each other Guide surfaces and the distance adjustment, it is also possible to guide products with a different diameter in the guide channel on the guide surfaces, as the point-shaped in cross-section of the guide channel abutment lines on the guide surfaces by the distance adjustment apart or towards each other to a larger or smaller diameter which corresponds to the diameter of the products after the format change.

Weiter wird vorgeschlagen, dass wenigstens zwei der Führungsflächen nach oben und nach unten und nach rechts und nach links zueinander bewegbar sind. Durch die vorgeschlagene Lösung kann die Geometrie des Führungskanals im Querschnitt beliebig an die Querschnittsgeometrie der Produkte des neuen Formats angepasst werden. Insbesondere kann der Führungskanal dabei im Querschnitt punktsymmetrisch zu einem Mittelpunkt vergrößert oder verkleinert werden, wenn alle Führungsflächen zueinander bewegbar sind.It is further proposed that at least two of the guide surfaces are movable up and down and to the right and to the left to each other. Due to the proposed solution, the geometry of the guide channel in cross section can be arbitrarily adapted to the cross-sectional geometry of the products of the new format. In particular, the guide channel can thereby be enlarged or reduced in cross-section point-symmetrical to a center when all the guide surfaces are mutually movable.

Weiter wird vorgeschlagen, dass die Führungsflächen der Führungsschiene und des Führungsteils jeweils paarweise in einem identischen Winkel, von bevorzugt 90 Grad, zueinander angeordnet sind. Durch die vorgeschlagene Ausrichtung der Führungsflächen ergibt sich eine gleichmäßige Führung der Produkte zu allen Seiten hin, wobei die Anlagelinien der in der Regel im Querschnitt kreisförmigen Produkte an den Führungsflächen der Führungsschiene und den Führungsflächen des Führungsteils immer einen identischen Abstand zueinander aufweisen.It is further proposed that the guide surfaces of the guide rail and the guide member are each arranged in pairs at an identical angle, preferably 90 degrees to each other. The proposed alignment of the guide surfaces results in a uniform guidance of the products on all sides, wherein the investment lines of the generally circular in cross-section products on the guide surfaces of the guide rail and the guide surfaces of the guide member always have an identical distance from each other.

Insbesondere wird vorgeschlagen, dass die Führungsflächen derart zueinander ausgerichtet und angeordnet sind, dass die beiden gegenüberliegenden Schnittlinien der Führungsflächen eine senkrechte und/oder eine horizontale Ebene aufspannen. Durch die vorgeschlagene Anordnung und Ausrichtung der Führungsflächen ergibt sich ein im Querschnitt punkt- und achsensymmetrischer Führungskanal mit einer entsprechend im Querschnitt symmetrischen Führung der Produkte.In particular, it is proposed that the guide surfaces are aligned and arranged relative to one another such that the two opposing cutting lines of the guide surfaces span a vertical and / or a horizontal plane. By the proposed arrangement and orientation of the guide surfaces results in a cross-sectional point and axis-symmetrical guide channel with a correspondingly symmetrical in cross-section leadership of the products.

Die Führung kann weiter verbessert werden, indem auch die aneinander angrenzenden Führungsflächen der Führungsschiene und des Führungsteils in einem identischen Winkel, von bevorzugt 90 Grad, zueinander angeordnet sind. Insgesamt ergibt sich dadurch ein symmetrischer, im Querschnitt bevorzugt quadratischer Führungskanal mit in der Querschnittsfläche punktsymmetrischen Berührungspunkten der Produkte an den Führungsflächen. Die Produkte werden dadurch bei möglichen auftretenden führungsbedingten Belastungen symmetrisch und in einem Winkel von 90 Grad versetzt zueinander angeordneten Berührungspunkten belastet.The guide can be further improved by also the adjoining guide surfaces of the guide rail and the guide member are arranged at an identical angle, preferably 90 degrees to each other. Overall, this results in a symmetrical, in cross section preferably square guide channel with points of symmetry in the cross-sectional area points of contact of the products on the guide surfaces. The products are thereby loaded symmetrically and at an angle of 90 degrees offset from each other at possible occurring leadership-related loads points of contact.

Weiter wird vorgeschlagen, dass die Führungsschiene, das Führungsteil oder Teile davon verschwenkbar ausgebildet sind. Durch die Verschwenkbarkeit der genannten Teile kann der durch die Führungsschiene und das Führungsteil gebildete Führungskanal bedarfsweise zu einer Seite hin geöffnet werden, so dass die Produkte durch die geöffnete Seite des Führungskanals bei einem Sensieren von Abweichungen von sensierten Kenngrößen von vorgegebenen Sollwerten aus dem vorgegebenen Transportweg abgeführt werden können.It is further proposed that the guide rail, the guide part or parts thereof are designed to be pivotable. As a result of the pivotability of the said parts, the guide channel formed by the guide rail and the guide part can be opened to one side as required so that the products are removed from the predetermined transport path through the open side of the guide channel when deviations from sensed characteristics are sensed can be.

In diesem Fall wird weiter vorgeschlagen, dass die Führungsschiene oder Teile davon um eine horizontal ausgerichtete und zu der Transportrichtung der Produkte senkrecht verlaufende Schwenkachse nach unten verschwenkbar sind. Durch die vorgeschlagene Ausrichtung der Schwenkachse und der dadurch ermöglichten Verschwenkbarkeit der Teile nach unten kann das Abführen der Produkte schwerkraftunterstützt erfolgen, so dass das bisher erforderliche aktive Ausblasen der Produkte entfallen kann.In this case, it is further proposed that the guide rail or parts thereof are pivotable downwards about a pivot axis oriented horizontally and perpendicular to the transport direction of the products. Due to the proposed orientation of the pivot axis and thereby enabled pivoting of the parts down the discharge can the products are gravity assisted, so that the previously required active blowing out of the products can be omitted.

Ferner können die Führungsschiene oder die Teile davon ausgehend von der Schwenkachse bis zu ihrem sich bis zu dem Ende der Führung der Vorrichtung erstreckenden Ende verschwenkbar sein. Das Ende der Führung der Vorrichtung ist z.B. das Ende der Vorrichtung, welches hinter einem Übernahmepunkt der Produkte von einem Längsförderer angeordnet ist. Durch die vorgeschlagene Lösung kann die Führungsschiene nach der Beendigung der sensierten Abweichung der Kenngröße vereinfacht wieder an die Vorrichtung herangeschwenkt werden, ohne dass die Bewegung der Führungsschiene oder der Teile davon durch auf der Führungsschiene gerade transportierte Produkte und Einklemmen derselben an einer gegenüberliegenden Kante eines sich in Transportrichtung der Produkte anschließenden Teils der Führungsschiene blockiert werden kann. Dies kann insbesondere dann der Fall sein, wenn die verschwenkbaren Teile nur einen Abschnitt des Führungskanals in Längsrichtung bilden und beim Zurückschwenken in die Ursprungslage an einer feststehenden Kante eines in Transportrichtung hinter dem verschwenkbaren Teil befindlichen anderen Teils des Führungskanals vorbeibewegt werden müssen. Durch die vorgeschlagene Lösung wird das gesamte Teil der Führungsschiene, welches in Transportrichtung nach der Schwenkachse den Führungskanal bildet, verschwenkt.Furthermore, the guide rail or the parts thereof, starting from the pivot axis to its up to the end of the guide of the device extending end can be pivoted. The end of the guide of the device is e.g. the end of the device, which is located behind a transfer point of the products of a longitudinal conveyor. Due to the proposed solution, the guide rail after the completion of the sensed deviation of the characteristic can be easily pivoted back to the device, without the movement of the guide rail or parts thereof by on the guide rail just transported products and pinching the same at an opposite edge of a in Transport direction of the products subsequent part of the guide rail can be blocked. This may in particular be the case when the pivotable parts form only a portion of the guide channel in the longitudinal direction and must be moved past the pivoting back to the original position on a fixed edge of a located in the transport direction behind the pivotable part other part of the guide channel. By the proposed solution, the entire part of the guide rail, which forms the guide channel in the transport direction after the pivot axis, pivots.

Weiter wird vorgeschlagen, dass die Führungsschiene und das Führungsteil symmetrisch zu einem gedachten Mittelpunkt des Führungskanals verstellbar ausgebildet sind. Die Führungsschiene und das Führungsteil können dadurch so verschoben werden, dass trotz des veränderten Abstandes die Mitte des Führungskanals in der Lage nicht verändert wird. Dazu können die Teile der Führungsschiene und des Führungsteils z.B. auch paarweise symmetrisch zueinander verstellt werden, so dass die Symmetrielinie des Führungskanals zwischen den zueinander verstellten Teilen nicht verschoben wird.It is further proposed that the guide rail and the guide part are designed to be adjustable symmetrically to an imaginary center of the guide channel. The guide rail and the guide part can thereby be moved so that despite the changed distance, the center of the guide channel is not changed in the situation. These can be the Parts of the guide rail and the guide part, for example, in pairs symmetrically adjusted to each other, so that the line of symmetry of the guide channel between the mutually adjusted parts is not moved.

Ferner kann in wenigstens einer Führungsfläche der Teile der Führungsschiene oder des Führungsteils eine Öffnung eines Saugluftkanals vorgesehen sein. Durch die Öffnung kann der Führungskanal mit Unterdruck beaufschlagt werden, wodurch eine bevorzugte Anlage der Produkte an dieser Führungsfläche bewirkt werden kann. Dadurch kann die Führung des Stranges in dem Führungskanal weiter verbessert werden. Insbesondere können dadurch unkontrollierte Bewegungen des Stranges in dem Führungskanal vermindert werden.Further, in at least one guide surface of the parts of the guide rail or the guide member may be provided an opening of a suction air passage. Through the opening of the guide channel can be subjected to negative pressure, whereby a preferred investment of the products can be effected on this guide surface. As a result, the guidance of the strand in the guide channel can be further improved. In particular, this uncontrolled movements of the strand can be reduced in the guide channel.

In diesem Fall kann wenigstens eine der Führungsflächen der Teile, welche der Führungsfläche mit der Öffnung des Saugkanals gegenüberliegt, bewegbar ausgebildet sein. Durch die vorgeschlagene Bewegbarkeit der gegenüberliegenden Führungsfläche kann diese von der Führungsfläche mit der Öffnung wegbewegt werden, so dass die Produkte des Stranges anschließend durch Aufbringen eines geringen Überdruckes in der Saugluftleitung oder dem Abschalten der Saugluft aus dem Transportweg ausgeführt bzw. ausgeblasen werden können. Sofern eine der unteren Führungsflächen bewegbar ausgebildet ist, reicht es dabei aus, die Saugluft abzuschalten, so dass die Produkte schwerkraftunterstützt nach unten aus dem Transportweg herausgeführt werden.In this case, at least one of the guide surfaces of the parts, which faces the guide surface with the opening of the suction channel, be designed to be movable. The proposed mobility of the opposite guide surface can be moved away from the guide surface with the opening, so that the products of the strand can then be executed or blown out by applying a slight overpressure in the suction air line or switching off the suction air from the transport path. If one of the lower guide surfaces is designed to be movable, it is sufficient to switch off the suction air, so that the products, guided by gravity, are led out of the transport path downward.

Die Erfindung wird im Folgenden anhand bevorzugter Ausführungsformen unter Bezugnahme auf die beigefügten Figuren erläutert. Dabei zeigt:

Fig. 1 und 2:
eine im Stand der Technik bereits bekannte Vorrichtung mit einem zur Stabilisierung der Produkte vorgesehenen Führungsteil; und
Fig. 3 bis 7:
eine erfindungsgemäß weiterentwickelte Vorrichtung mit einer Verstelleinrichtung.
The invention will be explained below with reference to preferred embodiments with reference to the accompanying figures. Showing:
1 and 2:
an already known in the prior art device with a provided for stabilizing the products guide part; and
3 to 7:
a device according to the invention further developed with an adjusting device.

In den Fig. 1 und Fig. 2 ist eine gattungsgemäße Vorrichtung zum längsaxialen Führen von Produkten 2, wie z.B. Zigaretten oder Filter, der Tabak verarbeitenden Industrie zu erkennen. Die Produkte 2 werden in einer Schneideinrichtung 1 von einem endlosen Strang 3 in einer vorbestimmten Länge abgeschnitten. Dazu wird der Strang 3 in zwei Tuben 9a und 9b geführt und von einem rotierenden Messerträger 6 mit einem radial vorstehenden Messer 7 durchtrennt. Die Schneidtuben 9a und 9b führen während des Schnittvorganges eine periodische Bewegung in Pfeilrichtung 11 aus und unterstützen dabei den Strang gegenüber den während des Schnittvorganges wirkenden seitlichen Kräften. Das Messer 7 führt während der Schnittbewegung ebenfalls eine komplexe rotatorische Bewegung um eine Drehachse aus, welche senkrecht zu der Drehachse des Messerträgers angeordnet ist, so dass auf das Messer 7 möglichst geringe Seitenkräfte wirken und die Relativbewegung des Stranges 3 zu dem Messer 7 so weit kompensiert wird, dass die Schnittkante der Produkte 2 senkrecht zu der Längsrichtung der Produkte 2 ausgerichtet ist. Selbstverständlich können auch mehrere parallel geführte endlose Stränge 3 und eine entsprechende Anzahl von parallel ausgerichteten Schneidtuben 9a und 9b vorgesehen sein.In the Fig. 1 and Fig. 2 is a generic device for longitudinal axial guidance of products 2, such as cigarettes or filters to recognize the tobacco processing industry. The products 2 are cut in a cutting device 1 by an endless strand 3 in a predetermined length. For this purpose, the strand 3 is guided in two tubes 9a and 9b and severed by a rotating knife carrier 6 with a radially projecting knife 7. The cutting tubes 9a and 9b perform during the cutting process a periodic movement in the direction of arrow 11 and thereby support the strand relative to the lateral forces acting during the cutting process. The knife 7 performs during the cutting movement also a complex rotational movement about an axis of rotation, which is arranged perpendicular to the axis of rotation of the knife carrier, so act on the knife 7 as low side forces and compensates the relative movement of the strand 3 to the knife 7 so far is that the cut edge of the products 2 is oriented perpendicular to the longitudinal direction of the products 2. Of course, a plurality of parallel endless strands 3 and a corresponding number of parallel aligned cutting tubes 9a and 9b may be provided.

Nach dem Abtrennen der Produkte 2 werden diese auf einer Vorrichtung 24 zum längsaxialen Führen weitertransportiert, wobei die Produkte 2 allein durch den angetriebenen Strang 3 weitergeschoben werden. Die Vorrichtung umfasst eine Führungsschiene 4 und ein Führungsteil 14. Das Führungsteil 14 ist oberhalb und vor Beginn der Führungsschiene 4 angeordnet und verhindert das Aufbäumen der angeschobenen Produkte 2. In der Führungsschiene 4 ist eine erste Führungsnut 8 vorgesehen, in der die Produkte 2 geführt werden. Ferner münden in die Führungsnut 8 mehrere Saugluftkanäle 12 mit daran angeschlossenen Saugluftleitungen 13, mit denen in der Führungsnut 8 ein Unterdruck zum Ansaugen der Produkte 2 erzeugbar ist. Soweit entspricht die Vorrichtung 24 dem aus der DE 38 00 431 C2 bekannten Stand der Technik.After separating the products 2, these are transported on a device 24 for longitudinal axial guidance, wherein the products 2 are pushed on solely by the driven strand 3. The device comprises a guide rail 4 and a guide member 14. The guide member 14 is disposed above and before the start of the guide rail 4 and prevents the rearing of the pushed products 2. In the guide rail 4, a first guide groove 8 is provided, in which the products 2 are performed. Furthermore, several suction air ducts 12 with suction air ducts 13 connected thereto open into the guide groove 8, with which a negative pressure for sucking the products 2 can be generated in the guide groove 8. As far as corresponds to the device 24 from the DE 38 00 431 C2 known prior art.

In den Fig. 3 bis Fig. 7 ist die erfindungsgemäß weiterentwickelte Vorrichtung 24 zu erkennen. Die Führungsschiene 4 ist hier durch zwei Teile 4a und 4b gebildet, welche jeweils eine Führungsfläche 18 und 19 aufweisen. Oberhalb der Teile 4a und 4b der Führungsschiene 4 ist ein Führungsteil 14 mit ebenfalls zwei Teilen 14a und 14b vorgesehen, welche ebenfalls zwei Führungsflächen 15 und 16 aufweisen. Die Führungsschiene 4 und das Führungsteil 14 sind damit zweiteilig ausgebildet. Die Teile 4a und 14a bzw. 4b und 14b sind jeweils unterschiedlichen Baugruppen 25 und 26 zugeordnet und können mittels einer Verstelleinrichtung 5 zueinander in Pfeilrichtung 20 bewegt werden, wodurch der Abstand zwischen den Teilen 4a und 4b bzw. 14a und 14b verändert werden kann.In the Fig. 3 to Fig. 7 the inventively further developed device 24 can be seen. The guide rail 4 is here formed by two parts 4a and 4b, which each have a guide surface 18 and 19. Above the parts 4a and 4b of the guide rail 4, a guide member 14 is also provided with two parts 14a and 14b, which also have two guide surfaces 15 and 16. The guide rail 4 and the guide member 14 are thus formed in two parts. The parts 4a and 14a or 4b and 14b are each assigned to different assemblies 25 and 26 and can be moved by means of an adjustment 5 to each other in the direction of arrow 20, whereby the distance between the parts 4a and 4b or 14a and 14b can be changed.

In dem zusammengebauten Zustand bilden die Führungsflächen 18 und 19 zusammen die erste Führungsnut 8, in welcher die Produkte 2 mit den Unterseiten aufliegen. Die Teile 14a und 14b des Führungsteils 14 führen die Produkte 2 an den Oberseiten, so dass sich die Produkte 2 nicht aus der vorgegebenen Transportrichtung aufbäumen können. Die Führungsflächen 15,16,18 und 19 bilden in der montierten Stellung einen in Umfangsrichtung nahezu vollständig geschlossenen Führungskanal 23 mit dem Führungsmittelpunkt M. Die Führungsflächen 15,16,18 und 19 sind derart geformt, dass sie oder ihre gedachten Verlängerungen in Winkeln A und B von jeweils 90 Grad zueinander ausgerichtet sind. Ferner sind die Führungsflächen 15,16,18 und 19 so zueinander ausgerichtet und angeordnet, dass die gegenüberliegenden Schnittlinien der Führungsflächen 15,16,18 und 19 eine senkrechte Trennebene E1 und eine horizontale Trennebene E2 aufspannen. Das Führungsteil 14 mit den Teilen 14a und 14b weist in der weiterentwickelten Lösung eine Länge von wenigstens einer Länge der Produkte 2 auf und ist oberhalb der Führungsschiene 4 angeordnet, so dass die Produkte 2 in dem Führungskanal 23 gleichzeitig an den Unterseiten und an den Oberseiten geführt werden. Durch die verbesserte Führung der Produkte 2 kann die Beaufschlagung der Führungsschiene 4 mit Saugluft entfallen.In the assembled state, the guide surfaces 18 and 19 together form the first guide groove 8, in which the products 2 rest with the undersides. The parts 14a and 14b of the guide part 14 guide the products 2 on the upper sides, so that the products 2 can not rear out of the predetermined transport direction. The guide surfaces 15,16,18 and 19 form in the mounted position a circumferentially almost completely closed guide channel 23 with the Guide center point M. The guide surfaces 15,16,18 and 19 are shaped such that they or their imaginary extensions are aligned at angles A and B of 90 degrees to each other. Further, the guide surfaces 15,16,18 and 19 are aligned and arranged to each other so that the opposite cutting lines of the guide surfaces 15,16,18 and 19 span a vertical parting plane E1 and a horizontal parting plane E2. The guide member 14 with the parts 14a and 14b in the further developed solution has a length of at least a length of the products 2 and is arranged above the guide rail 4, so that the products 2 are guided in the guide channel 23 at the same time on the lower sides and on the upper sides become. Due to the improved guidance of the products 2, the admission of the guide rail 4 with suction air can be omitted.

Mittels der Verstelleinrichtung 5 kann der Abstand des Teils 4a zu dem Teil 4b der Führungsschiene 4 und der Abstand des Teils 14a zu dem Teil 14b des Führungsteils 14 verändert werden, wobei der Mittelpunkt M des Führungskanals 23 bei einer Abstandsverstellung in der Lage nicht verändert wird. Die Baugruppen 25 und 26 werden bei einer Verstellung jeweils zusammen mit den Teilen 4a,14a und 4b,14b gegeneinander verschoben, so dass der Führungskanal 23 vergrößert wird. Durch die Vergrößerung des Abstandes der Teile 4a,14a zu den Teilen 4b,14b des Führungskanals 23 wird gleichzeitig der Abstand der die senkrechte Ebene E1 aufspannenden Schnittlinien der Führungsflächen 15 und 16 und 18 und 19 vergrößert, so dass sich ein erheblich größerer Führungskanal 23 ergibt, in dem die Produkte 2 dennoch an den Führungsflächen 15,16,18 und 19 an der Unterseite und der Oberseite geführt werden. Durch die beschriebene sehr einfache Vergrößerung des Führungskanals 23 kann die Vorrichtung sehr einfach zum Führen von Produkten 2 mit einem anderen Durchmesser umgerüstet werden. Die Teile 4a und 4b der Führungsschiene 4 und die Teile 14a und 14b des Führungsteils 14 sind in der vorgeschlagenen Weiterentwicklung als getrennte Bauteile ausgeführt und zudem zueinander abstandsveränderbar. Trotzdem bilden die Führungsflächen 15 und 16 an den Teilen 4a und 4b zusammen die Führungsnut 8, in der die Produkte 2 aufliegen. Gleiches gilt für die Teile 14a und 14b, welche mit den Führungsflächen 18 und 19 eine zweite Führungsnut 10 bilden, die achsensymmetrisch zu der ersten Führungsnut 8 angeordnet und ausgerichtet ist.By means of the adjusting device 5, the distance of the part 4a to the part 4b of the guide rail 4 and the distance of the part 14a can be changed to the part 14b of the guide member 14, wherein the center M of the guide channel 23 is not changed in a positional adjustment in position. The assemblies 25 and 26 are each moved together with the parts 4a, 14a and 4b, 14b against each other in an adjustment, so that the guide channel 23 is increased. By increasing the distance of the parts 4a, 14a to the parts 4b, 14b of the guide channel 23, the distance of the vertical plane E1 spanning cut lines of the guide surfaces 15 and 16 and 18 and 19 is increased simultaneously, so that there is a considerably larger guide channel 23 in which the products 2 are nevertheless guided on the guide surfaces 15, 16, 18 and 19 on the underside and the upper side. Due to the described very simple enlargement of the guide channel 23, the device can very easily for guiding products 2 with a be converted to another diameter. The parts 4a and 4b of the guide rail 4 and the parts 14a and 14b of the guide member 14 are executed in the proposed development as separate components and also with respect to each other distance. Nevertheless, the guide surfaces 15 and 16 at the parts 4a and 4b together form the guide groove 8 in which the products 2 rest. The same applies to the parts 14a and 14b, which form a second guide groove 10 with the guide surfaces 18 and 19, which is arranged and aligned axially symmetrically to the first guide groove 8.

In den Fig. 5, Fig. 6 und Fig. 7 ist eine Weiterentwicklung der Erfindung zu erkennen, bei der die Teile 4a und 4b der Führungsschiene 4 zusammen um eine horizontal und senkrecht zu der Transportrichtung T der Produkte 2 verlaufenden Schwenkachse 17 nach unten verschwenkbar sind. In dem in der Fig. 5 dargestellten Ausführungsbeispiel ist dabei nur ein Abschnitt der Führungsschiene 4 verschwenkbar, während in dem in der Fig. 7 gezeigten Ausführungsbeispiel die Führungsschiene 4 insgesamt bis zu ihrem Ende hin, d.h. ausgehend von der Schwenkachse über die gesamte Länge verschwenkbar ausgebildet ist.In the Fig. 5 . Fig. 6 and Fig. 7 shows a further development of the invention, in which the parts 4a and 4b of the guide rail 4 are pivotable together about a horizontally and perpendicular to the transport direction T of the products 2 extending pivot axis 17 downwards. In the in the Fig. 5 illustrated embodiment, only a portion of the guide rail 4 is pivotable while in the in the Fig. 7 shown embodiment, the guide rail 4 in total up to its end, that is, starting from the pivot axis over the entire length is formed pivotable.

Für den Fall, dass die Gesamtvorrichtung gerade angefahren wird, und der Strang noch nicht vollständig fixiert ist, oder bei einer sensierten Abweichung der Kenngrößen von vorgegebenen Sollwerten, wird die Führungsschiene 4 mit den Teilen 4a und 4b nach unten verschwenkt und die Produkte 2 schwerkraftunterstützt aus dem Transportweg herausgeführt.In the event that the entire device is just started, and the strand is not completely fixed, or in a sensed deviation of the characteristics of predetermined target values, the guide rail 4 is pivoted with the parts 4a and 4b down and the products 2 gravity assisted led out the transport route.

Zusätzlich kann in einem der Teile 4a,4b der Führungsschiene 4 oder der Teile 14a,14b des Führungsteils 14 ein mit Unterdruck beaufschlagbarer Saugluftkanal vorgesehen sein, über den der Führungskanal 23 zu einer weiter verbesserten Führung der Produkte mit Unterdruck beaufschlagbar ist. Dies hat ferner den Vorteil, dass das Auswerfen der Produkte 2 durch eine Steuerung des Unterdrucks aktiv unterstützt werden kann. In diesem Fall ist es z.B. auch denkbar, nur eines der Teile 4a,4b,14a und 14b zu verschwenken, und die Produkte 2 seitlich oder schräg aus dem Transportweg auszublasen. Ferner kann durch die Saugluft auch eine bevorzugte Anlage der Produkte an einer der Führungsflächen 15,16,18 oder 19 bewirkt werden.In addition, in one of the parts 4a, 4b of the guide rail 4 or the parts 14a, 14b of the guide member 14 may be provided with a vacuum acted upon suction air duct, via which the Guide channel 23 to a further improved management of products with negative pressure can be acted upon. This also has the advantage that the ejection of the products 2 can be actively supported by a control of the negative pressure. In this case, it is also conceivable, for example, to pivot only one of the parts 4a, 4b, 14a and 14b, and to blow the products 2 laterally or obliquely out of the transport path. Furthermore, by the suction air and a preferred investment of the products on one of the guide surfaces 15,16,18 or 19 can be effected.
