Description

Die Erfindung betrifft eine Pappenmaschine zur Herstellung von Pappebogen mit einer Einrichtung zum Erzeugen von Wellen in nassem Zustand, bei der einer ein Tragrollen- und ein Formrollenband aufweisenden Welleinrichtung ein Querablauf für die Bogen vorgeschaltet ist, welcher die Transportrichtung der Bogen um 90° dreht, und bei der die Welleinrichtung gleichzeitig den Einlauf in einen Kanaltrockner bildet (nach Patentanmeldung P 22 27 824.6).The invention relates to a cardboard machine for the production of cardboard sheets with a device for Generation of waves in the wet state, in which one has a carrier roller belt and a forming roller belt Upstream shaft device is a transverse drain for the sheet, which determines the transport direction of the sheet rotates by 90 °, and in which the shaft device simultaneously forms the inlet into a tunnel dryer (according to patent application P 22 27 824.6).

Bei der Welleinrichtung dieser Pappenmaschine bereitet die Führung der verschiedenen Bänder, so daß die Rohre des Tragrollenbandes und diejenigen des Formrollenbandes stets mittig ineinanderliegen, Schwierigkeiten. Diese Forderung ist aber unabdingbar, da die nassen Pappebogen zwischen diesen Bändern geformt werden und, werden die Rohre nicht genau mittig ineinandergeführt, das Endprodukt entsprechend schlecht gewellt wird, also Ausschuß darstellt.In the corrugation of this cardboard machine prepares the leadership of the various bands, so that the tubes of the idler belt and those of the forming roller belt are always centered one inside the other, Trouble. However, this requirement is indispensable because the wet cardboard sheets between these belts and, if the tubes are not inserted exactly in the middle, the end product accordingly is badly curled, so it represents scrap.

Um eine stets mittige gegenseitige Führung zwischen den Rollen des Tragrollenbandes und denjenigen den Formrollenbandes zu erreichen, wird nach der Erfindung vorgeschlagen, daß die Rollen des Tragrollenbandes wie auch die Rollen des Formrollenbandes in Ketten geführt sind, daß die Kette des Tragrollenbandes die Rollen des Formrollenbandes erfassende Mitnehmernocken aufweist und daß lediglich die Kette des Tragrollenbandes über Kettenräder angetrieben ist.In order to always have a central mutual guidance between the roles of the idler belt and those who To achieve forming roller belt, it is proposed according to the invention that the rollers of the supporting roller belt as well as the roles of the form roller belt are guided in chains that the chain of the idler belt Has rollers of the form roller belt detecting driver cams and that only the chain of the Conveyor roller belt is driven by sprockets.

Nach der Erfindung werden demnach die beiden Bänder nicht mehr unabhängig voneinander geführt und angetrieben, sondern lediglich das Tragrollenband wird angetrieben, und nimmt mittels der formschlüssigen Verbindung über die Mitnehmernocken die Rohre des Formrollenbandes mit. Dadurch ist stets eine exakte Lage der Rohre des Formrollenbandes relativ zu denjenigen des Tragrollenbandes und damit auch die erstrebte gleichmäßige Wellung der Pappebogen gewährleistet.According to the invention, the two bands are therefore no longer performed independently of one another and driven, but only the conveyor roller belt is driven and takes place by means of the form-fitting Connection via the driver cams with the tubes of the forming roller belt. This is always an exact Position of the tubes of the forming roller belt relative to those of the supporting roller belt and thus also the Strived for even corrugation of the cardboard sheets guaranteed.

Um unvermeidbare Längentoleranzen beim Durchführen der Bänder durch den Kanaltrockner auszugleichen, empfiehlt es sich, die Glieder der Kette des Formrollenbandes jeweils mit Spiel miteinander zu verbinden. Dadurch können sich die Rohre dieses Bandes einer eventuellen Längenveränderung desIn order to compensate for unavoidable length tolerances when feeding the belts through the tunnel dryer, it is advisable to close the links of the chain of the roller belt with play with one another associate. As a result, the tubes of this band can experience a possible change in length of the

•o Tragrollenbandes anpassen, so daß jeweils wiederum die mittige Anordnung der Rollen des Formrollenbandes relativ zu den Rollen des Tragrollenbandes gewährleistet ist.• o Adjust the idler belt so that each turn the central arrangement of the rollers of the forming roller belt relative to the rollers of the supporting roller belt is guaranteed.

F i g. 1 eine Anordnungsskizze,
F i g. 2 ein Formrollenband, teilweise geschnitten und Fig.3 die Seitenansicht eines Formrollenbandes im Eingriff in ein Tragrollenband.In the drawing, the device according to the invention is shown schematically, namely shows
F i g. 1 an arrangement sketch,
F i g. FIG. 2 shows a form roller belt, partially in section, and FIG. 3 shows the side view of a form roller belt in engagement with a carrier roller belt.

Über eine Rollenbahn 3 und Lehrrollen 6 werden Pappebogen 2 in Transportrichtung 4 einer Welleinrichtung 7 zugeführt. Die Welleinrichtung 7 wird gebildet durch ein unteres Tragrollenband 8 und ein darüber angeordnetes, in dieses Tragrollenband 8 eingreifendes Formrollenband 9. Die Welleinrichtung 7 bildet gleichzeitig den Einlauf in einen Kanaltrockner 10 und führt die gewellten Pappebogen mit einer gegenüber der Zuführgeschwindigkeit 4 etwas geringeren Geschwindigkeit 14 in bzw. durch den Kanaltrockner 10.Via a roller conveyor 3 and teaching rollers 6, cardboard sheets 2 are moved in the transport direction 4 of a corrugating device 7 supplied. The wave device 7 is formed by a lower support roller belt 8 and one above arranged, in this supporting roller band 8 engaging form roller band 9. The wave device 7 forms at the same time the inlet into a tunnel dryer 10 and leads the corrugated cardboard sheet with an opposite the feed speed 4 is somewhat slower speed 14 in or through the tunnel dryer 10.

Die Bänder 8, 9 werden gebildet durch Rollen 13, 16 die jeweils beidseits durch Ketten 21, 22 gehalten sind. Die einzelnen Kettenglieder der Kette 21 des Tragrollenbandes 8 weisen Mitnehmernocken 12 auf, die beim Zusammenlaufen des Tragrollenbandes 8 mit dem Formrollenband 9 die Rohre 13 des Formrollenbandes 9 zwischen sich erfassen. Angetrieben wird lediglich das Tragrollenband 8 über Kettenräder 23.The belts 8, 9 are formed by rollers 13, 16 which are each held on both sides by chains 21, 22. The individual chain links of the chain 21 of the roller conveyor belt 8 have driver cams 12, when the conveyor roller belt 8 converges with the forming roller belt 9, the tubes 13 of the forming roller belt 9 grasp between them. Only the carrier roller belt 8 is driven via chain wheels 23.

In Fig.3 ist in Seitenansicht der Eingriff des Formrollenbandes 9 in das Tragrollenband 8 dargestellt.In Figure 3, the engagement of the Form roller belt 9 is shown in the carrier roller belt 8.

Die Kette 21 des Tragrollenbandes 8 wird auf einer Schiene 11 geführt. Die einzelnen Kettenglieder dieser Kette 21 tragen die Rohre 16 des Tragrollenbandes 8 und weisen Mitnehmernocken 12 auf, die die Rohre 13 des Formrollenbandes 9 zwischen sich erfassen.The chain 21 of the roller conveyor belt 8 is guided on a rail 11. The individual chain links of this Chain 21 carry the tubes 16 of the conveyor roller belt 8 and have driver cams 12 which the tubes 13 of the forming roller belt 9 grasp between them.

Dadurch wird nicht nur das Formrollenband 9 mitgenommen, sondern auch dafür gesorgt, daß sich die Rohre 13 des Formrollenbandes stets mittig zwischen den Rohren 16 des Tragrollenbandes 8 befinden.This not only takes the form roller band 9 with it, but also ensures that the Tubes 13 of the forming roller belt are always located centrally between the tubes 16 of the supporting roller belt 8.

Um eine Anpassung an Längenveränderungen des Tragrollenbandes 8 zu erreichen, weisen die einzelnen Kettenglieder 19,20 der Kette 22 des Formrollenbandes 9 gegenseitig Spiel auf. Dies wird dadurch erreicht, daß die Befestigungsbolzen 17 der Kettenglieder 19 einen geringfügig kleineren Durchmesser aufweisen als der lichte Durchmesser einer Buchse 18 im darauffolgenden Kettenglied 20. Um diese Durchmesserdifferenz di—d\ kann sich die Kette 22 und damit auch der gegenseitige Abstand zwischen den Rollen 13 verändern, so daß auch bei Längenänderungen des Tragrollenbandes 8 stets eine einwandfreie Anpassung der gegenseitigen Lage der Rollen 13,16 möglich ist.In order to adapt to changes in length of the roller conveyor belt 8, the individual chain links 19, 20 of the chain 22 of the roller conveyor belt 9 have mutual play. This is achieved in that the fastening bolts 17 of the chain links 19 have a slightly smaller diameter than the inside diameter of a bushing 18 in the following chain link 20. The chain 22 and thus also the mutual distance between the rollers can move around this difference in diameter di-d \ 13 change so that a perfect adjustment of the mutual position of the rollers 13, 16 is always possible even with changes in the length of the supporting roller belt 8.
