Description

Die Erfindung betrifft eine Weiche für eine in ihrer Transportrichtung in mehrere Teil-Bahnen aufzuteilende Bahn, insbesondere eine Wellpappe-Bahn.The invention relates to a switch for a in its transport direction in several partial webs to be split web, especially a corrugated web.

Derartige Weichen weisen quer zur Transportrichtung mehrere Weichen-Elemente auf, die nebeneinander und unterhalb der Bahn angeordnet sind und die einzeln mindestens in eine obere Weichen-Stellung und eine untere Weichen-Stellung bewegbar sind. Zur Durchführung dieser Bewegungen sind Verstell-Antriebe vorgesehen, die die einzelnen Weichen-Elemente zwischen ihren Weichen-Stellungen bewegen. Derartige Weichen werden in Anlagen zur Bearbeitung, und zwar insbesondere zum Aufteilen von Bahnen, insbesondere Wellpappe-Bahnen, angeordnet, wobei die Teil-Bahnen, bei denen es sich meistens um zwei Teil-Bahnen handelt, einer Querschneide-Einrichtung zugeführt werden, in denen die einzelnen Teil-Bahnen in einzelne Bahnabschnitte, sogenannte Nutzen, zerschnitten und einer Ablage zugeführt werden. Die einzelnen Querschneider einer solchen Querschneide-Einrichtung sind übereinander angeordnet. Während eines ununterbrochenen Transportes der Teil-Bahnen befinden sich die einer oberen Teil-Bahn zugeordneten Weichen-Elemente in ihrer oberen Weichen-Stellung, während die einer unteren Teil-Bahn zugeordneten Weichen-Elemente sich in ihrer unteren Weichen-Stellung befinden. Bei einem Format-Wechsel, das heißt bei einer Änderung der Breite der Teil-Bahnen, wird die Bahn insgesamt quer durchgeschnitten und die voreilenden Teil-Bahnen beschleunigt abgezogen. Hierdurch entsteht eine Lücke zwischen den voreilenden Teil-Bahnen und den nacheilenden Teil-Bahnen. Während sich die Lücke zwischen diesen Teil-Bahnen im Bereich der Weiche befindet, werden die Weichen-Elemente derart verstellt, dass sie über ihre Breite den nacheilenden Teil-Bahnen richtig zugeordnet sind. Um insbesondere die Teil-Bahnen auf den Weichen-Elementen zu halten, ist es hierbei bekannt, über die volle Breite der Bahn ein Rohr mit zahlreichen nach unten gerichteten Austrittsöffnungen vorzusehen, durch das Druckluft geblasen wird. Insbesondere wenn die nacheilenden Teil-Bahnen in die Weiche einlaufen, treten große Luftverwirbelungen auf, die dazu führen können, dass die Teil-Bahnen nicht ordnungsgemäß auf ihrem Weg zu den Querschneidem der Querschneide-Einrichtung eingeführt werden. Insbesondere hat sich gezeigt, dass von der unteren Teil-Bahn ein Luftstrom reflektiert wird, der die obere Teil-Bahn von den Weichen-Elementen abhebt und aufsteigen lässt. Je höher die Bahngeschwindigkeiten werden, umso größer wird dieses Problem. Derartige Bahngeschwindigkeiten können über 300 m/min betragen.Such switches have transversely to the transport direction a plurality of points elements on, which are arranged side by side and below the track and the individually at least in an upper switch position and a lower Switch point position are movable. To carry out these movements are provided adjusting drives, which are the individual points elements move between their points positions. Such switches are in equipment for processing, in particular for splitting Webs, in particular corrugated webs, wherein the sub-webs, which are mostly two sub-orbits, one Cross-cutting device are fed, in which the individual sub-webs into individual track sections, so-called benefits, cut and a tray to be supplied. The individual sheeters of such a Cross-cutting device are arranged one above the other. During one Continuous transport of the sub-orbits are those of an upper one Part-track assigned points elements in their upper points position, while the switch elements associated with a lower sub-track are in their lower points position. At a Format change, that is, when changing the width of the sub-webs, the track is cut across and the leading partial lanes accelerated deducted. This creates a gap between the leading sub-lanes and the lagging sub-lanes. While the gap between these sub-webs is in the area of the switch, the switch elements are adjusted so that they are across their width are assigned correctly to the trailing sub-lanes. In particular to keep the sub-webs on the points elements, it is known here, across the full width of the railway a tube with numerous down to provide directed outlet openings, blown through the compressed air becomes. In particular, when the trailing part-tracks run into the switch, Large air turbulences occur, which can lead to the sub-webs are not properly on their way to the cross-cutting the cross-cutting device are introduced. In particular shown that an air flow is reflected by the lower sub-orbit, which lifts the upper part of the track elements and ascend leaves. The higher the web speeds become, the larger becomes this problem. Such web speeds can be over 300 m / min be.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Weiche der gattungsgemäßen Art so auszugestalten, dass bei einem Formatwechsel eine sichere Führung der nacheilenden Teil-Bahnen gewährleistet ist.The invention is therefore based on the object, a switch of the generic type To design Art so that when a format change a safe guidance of the lagging part-tracks is guaranteed.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst. Der Kern der Erfindung liegt darin, dass über die Breite einer Bahn mehrere einzeln ansteuerbare Druckluft-Düsen vorgesehen sind, so dass die Teil-Bahnen sicher auf den sie führenden Weichen-Elementen gehalten werden, und zwar insbesondere unmittelbar nach einem Format-Wechsel. Das Ansteuern der Druckluft-Düsen kann in geeigneter Weise erfolgen, beispielsweise kann die Beaufschlagung der dem Längsschnitt zwischen den nacheilenden Teil-Bahnen unmittelbar benachbarten Druckluft-Düsen unterbleiben, um Druckluftverwirbelungen auszuschließen. Das erfindungsgemäße Ziel lässt sich in besonders vorteilhafter Weise durch die weitere Ausgestaltung nach Anspruch 2 erreichen. Weiterhin ist es von Vorteil, wenn nach Anspruch 3 eine oder mehrere Druckluft-Düsen oberhalb jedes Weichen-Elementes angeordnet sind.This object is achieved by the features of the claim 1 solved. The essence of the invention is that across the width of a Railway several individually controllable compressed air nozzles are provided so that the sub-trains safely on the leading turnout elements held, in particular immediately after a format change. The driving of the compressed air nozzles can be done in a suitable manner take place, for example, the admission of the longitudinal section between the trailing sub-webs immediately adjacent compressed air nozzles Stay out of order to prevent compressed air turbulence. The The aim of the invention can be achieved in a particularly advantageous manner reach the further embodiment according to claim 2. It is still from Advantage, if according to claim 3, one or more compressed air nozzles above each switch element are arranged.

Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Ansprüchen 4 und 5.Further advantageous embodiments will become apparent from the claims. 4 and 5.

Die erfindungsgemäße Lösung lässt sich nicht nur mit Vorteil dort einsetzen, wo bei einem Format-Wechsel die Bahn vollständig durchgeschnitten und die voreilenden Teil-Bahnen beschleunigt abgezogen werden, sondern auch bei einem sogenannten spaltfreien Format-Wechsel, wenn lediglich Teil-Querschnitte angebracht werden.The solution according to the invention can not only be used with advantage there, where in a format change the web completely cut through and the leading sub-orbits will be accelerated, but instead even with a so-called gap-free format change, if only Part cross sections are attached.

It is about around an upper table 9 leading to the upper cross cutter 10 of the duplex cross cutting device 7 leads and a lower table 11, which leads to the lower Cross cutter 12 of the duplex cross-cutting device 7 leads. In the Switch 6 are the actual switch elements 13 so-called type Paddles running. These switch elements 13 consist of side by side and mutually parallel bars with a width of, for example about 10 cm across the transport direction 1, which is a common Pivot axis 14 are pivotally mounted adjacent to the table 8 is. Each switch element 13 is by means of a linear drive, for example a pneumatically actuated piston-cylinder drive 15, pivotable between a lower and an upper position, in 1 and 3 is indicated. In the upper position they are aligned accordingly pivoted points elements 13 with the upper table 9, while in the lower position, the corresponding switch elements 13th are aligned with the lower table 11.

Soweit dieser Anlagen-Teil bisher beschrieben worden ist, ist er allgemein bekannt und in der Praxis verbreitet.As far as this system part has been described so far, it is general known and disseminated in practice.

Über jedem Weichen-Element 13 ist eine Druckluft-Düse 16 angeordnet, die im Wesentlichen senkrecht von oben auf das Weichen-Element 13 gerichtet ist. Die Düsen 16 sind jeweils - bezogen auf eine Richtung quer zur Transportrichtung 1 - mittig über den Weichen-Elementen 13 angeordnet. Sie befinden sich weiterhin in der Nähe der den Tischen 9, 11 zugewandten freien Enden 17 der Weichen-Elemente 13.Above each switch element 13, a compressed air nozzle 16 is arranged, directed substantially perpendicularly from above onto the switch element 13 is. The nozzles 16 are each - with respect to a direction transverse to Transport direction 1 - arranged centrally over the points elements 13. You are still near the tables 9, 11 facing free ends 17 of the points elements 13th

Jede Düse 16 ist über eine eigene Versorgungs-Leitung 18 von einer Ventil-Einheit 19 mit Druckluft beaufschlagbar. Diese Ventil-Einheit 19 wird wiederum von einer zentralen Druckluft-Quelle 20 und einem der Konstanthaltung des Luftdruckes dienenden Druck-Luft-Speicher 21 mit Druckluft versorgt. Die Ansteuerung der Ventil-Einheit 19 erfolgt von einer zentralen Steuer-Einheit 22, über die auch die Ansteuerung der Antriebe 15 erfolgt. Diesen ist ebenfalls eine zentrale Ventil-Einheit 23 vorgeordnet, die von der Druckluft-Quelle 20 aus versorgt wird.Each nozzle 16 is via its own supply line 18 from a valve unit 19 acted upon by compressed air. This valve unit 19 is in turn from a central compressed air source 20 and one of the constant maintenance the air pressure serving pressure-air storage 21 with Compressed air supplied. The control of the valve unit 19 is effected by a central control unit 22, via which also the control of the drives 15 takes place. These are also preceded by a central valve unit 23, which is supplied from the compressed air source 20 from.

Die Arbeitsweise ist wie folgt:The working method is as follows:

In Transportrichtung 1 vorlaufend befindet sich eine Bahn 2a auf dem oberen Tisch 9, die in den oberen Querschneider 10 einläuft und dort in einzelne Abschnitte zerteilt und einer nicht dargestellten Ablage zugeführt wird. Eine weitere Teil-Bahn 2b befindet sich auf dem unteren Tisch 11 und läuft in den unteren Querschneider 12 der Duplex-Querschneid-Einrichtung 7 ein und wird dort in gleicher Weise in Abschnitte geschnitten und einer Ablage zugeführt. Die beiden Teil-Bahnen 2a und 2b waren zuvor in der Längs-Schneid-Einrichtung 5 durch einen Längsschnitt aus der Bahn 2 gebildet worden.Advancing in the transport direction 1 is a web 2a on the upper Table 9, which enters the upper cross cutter 10 and there in individual Parts divided and fed to a tray, not shown becomes. Another partial path 2b is located on the lower table 11 and runs into the lower cross cutter 12 of the duplex cross cutter 7 and is cut there in the same way in sections and a tray supplied. The two sub-webs 2a and 2b were previously in the longitudinal cutting device 5 by a longitudinal section of the Track 2 has been formed.

Bei dem in der Zeichnung angedeuteten Format-Wechsel ist die Bahn insgesamt durch einen mit 24 bezeichneten Quer-Schnitt quer durchtrennt worden. Die voreilenden Teil-Bahnen 2a und 2b werden in der Duplex-Querschneid-Einrichtung 7 beschleunigt, so dass eine Lücke 25 zwischen den voreilenden Teil-Bahnen 2a und 2b und den nachfolgenden Teil-Bahnen 2c und 2 d entsteht. Diese sind durch einen Längs-Schnitt 26 an anderer Stelle als die beiden Teil-Bahnen 2a und 2b unterteilt, wie es bei einem Format-Wechsel üblich ist. In the indicated in the drawing format change is the total train transected transversely through a cross-section designated 24 Service. The leading partial paths 2a and 2b are in the duplex cross-cutting device 7 accelerates, leaving a gap 25 between the leading sub-webs 2a and 2b and the subsequent sub-webs 2c and 2 d is created. These are by a longitudinal section 26 at subdivided elsewhere than the two sub-orbits 2a and 2b, as in a format change is common.

Während die Lücke 25 zwischen den Teil-Bahnen 2a, 2b einerseits und 2c, 2d andererseits sich über der Weiche 6 befindet, werden die Weichen-Elemente 13 durch entsprechende Beaufschlagung der Antriebe 15 so verschwenkt, dass über die Breite der Teil-Bahn 2c die Weichen-Elemente 13 nach oben geschwenkt sind, so dass diese Teil-Bahn 2c auf den oberen Tisch 9 geleitet wird, während die sich über die Breite der Teil-Bahn 2d erstreckenden Weichen-Elemente 13 sich in ihrer unteren Stellung befinden, so dass die Teil-Bahn 2d auf den unteren Tisch 11 geleitet wird. Dadurch, dass insbesondere während dieses Format-Wechsels die Druckluft-Düsen 16, die der auf den unteren Tisch 11 zu leitenden Teil-Bahn 2d zugeordnet sind, mit Druckluft beaufschlagt werden, wird diese Teil-Bahn 2d zuverlässig auf den in ihrer unteren Schwenk-Lage befindlichen Weichen-Elementen 13 gehalten und durch den Spalt 27 zwischen dem oberen Tisch 9 und dem unteren Tisch 11 auf den unteren Tisch 11 geleitet. Die der oberen Teil-Bahn 2c zugeordneten Druckluft-Düsen 16 können gleichermaßen während dieses Format-Wechsels mit Druckluft beaufschlagt werden, wodurch zuverlässig ein Aufsteigen der auf den oberen Tisch 9 zu leitenden Teil-Bahn 2c von den Weichen-Elementen 13 vermieden wird. Es ist auch möglich, eine oder zwei Düsen 16 im Bereich des Längs-Schnittes 26 unbeaufschlagt zu lassen, um in diesem Grenzbereich zwischen den beiden Teil-Bahnen 2c, 2d Luftverwirbelungen zu vermeiden.While the gap 25 between the partial webs 2a, 2b on the one hand and 2c, 2d, on the other hand, is located above the switch 6, the points elements 13 pivoted by appropriate action of the drives 15, that over the width of the sub-web 2c, the points elements 13th are pivoted upward, so that this sub-train 2c on the upper Table 9 is routed while extending across the width of the sub-web 2d extending switch elements 13 are in their lower position, so that the sub-web 2d is directed onto the lower table 11. Thereby, that in particular during this format change the compressed air nozzles 16, which is assigned to the lower table 11 to be guided partial web 2d are pressurized with compressed air, this sub-lane 2d reliable on the switch elements located in their lower pivot position Held 13 and through the gap 27 between the upper table 9 and the lower table 11 passed to the lower table 11. The top one Part-orbit 2c associated compressed air nozzles 16 can equally During this format change, compressed air is applied to it reliably ascending the on the upper table 9 to be conductive Part-track 2c is avoided by the switch elements 13. It is also possible, one or two nozzles 16 in the region of the longitudinal section 26 unencumbered to let in to this boundary between the two Part-tracks 2c, 2d to avoid air turbulence.
