Abstract

An appts. for wet forming corrugated cardboard sheets from cardboard sheet, drawn away from a circular sieve cardboard prodn. machine, comprises in succession in the processing direction a transverse discharge, an unheated corrugating device and a channel drier with a roller support belt. The corrugating device consists of the roller support belt passing through the channel drier and engaging a forming roller belt, both belts being formed by tubes of equal dia. articulated at each end to the links of a drive chain having at least the length of a cardboard sheet, while a retaining belt is provided as the forming roller belt engages the roller support belt. In the improvement, the forming roller belt and opt. the retaining belt is positively connected to the roller support belt via pin wheel teeth. The system enables complete and exact corrugations to be produced in the wet cardboard, and provides for compensation of unavoidable length tolerances in the transport of the belts through the channel drier. In addn. the forming roller belt is combined with the retaining belt to form a single forming-retaining belt.

Description

Einrichtung zum Verformen von Pappebogen Die Erfindung betrifft eine Einrichtung zum nassen Verformen von, von einer Rundsieb-Kartonmaschine abgezogenen Pappebogen zu Pappe-Wellplatten die durch eine in Bearbeitungsrichtung aufeinanderfolgend Anordnung eines an sich bekannten Quer-Ablaufs, einer unbeheizten Welleinrichtung und eines Kanaltrockners mit Rollen-Trageband gekennzeichnet ist, wobei die Welleinrichtung aus dem durch den Kanaltrockner geführten Rollen-Trageband und einem darin eingreifendem Form-Rollenband besteht und beide Bänder aus beidseits an die Glieder von Antriebsketten angelenkten Rohren gleichen Durchmessers gebildet sind, die mindestens die Länge eines Pappebogens aufweisen und wobei ein wie das Form-Rollenband in das tragband eingreifendes Halteband vorgesehen ist. (Nach Patentanmeldung P 22 27 824.6).Device for deforming cardboard sheets The invention relates to a Device for the wet deformation of drawn off from a cylinder mold cardboard machine Cardboard sheets to cardboard corrugated sheets which are successively followed by one in the processing direction Arrangement of a known transverse drain, an unheated shaft device and a duct dryer with roller carrying tape, wherein the corrugating device from the roller carrying strap passed through the tunnel dryer and one that engages in it Form roller belt consists and both belts from both sides to the links of drive chains hinged pipes of the same diameter are formed, which is at least the length of a cardboard sheet and wherein a like the form roller tape in the carrier tape engaging tether is provided. (According to patent application P 22 27 824.6).

Bei der noch nicht zum Stande der Technik gehörenden Einrichtung, bereitete die Führung der verschiedenen Bänder so, daß die Rohre des Rollen-Tragebandes und diejenigen des Porm-RoDenbandes beziehungsweise des Haltebandes stets mittig ineinander lagen, Schwierigkeiten. Diese Forderung ist aber unabdingbar, da die nassen Pappebogen zwischen diesen Bändern geformt werden und damit werden die Rohre nicht genau mittig ineinandergeführt, das Endprodukt auch entsprechend schlecht gewellt wira. Tan hat sich daher so beholfen, daß man verhältnismäßig kurze Längen der Bänder ineinander geführt hat, um ein Auseinanderlaufen der Bänder zu vermeiden. Dies ergab jedoch Schwierigkeiten beim Übergang zwischen den einzelnen Bändern.In the case of the facility that does not yet belong to the state of the art, prepared the guidance of the various tapes so that the tubes of the roller carrying tape and those of the Porm-RoDenbandes or the retaining strap are always in the middle lying inside each other, difficulties. However, this requirement is essential because the wet cardboard sheets are formed between these tapes and thus the tubes are formed not exactly in the middle, the end product is correspondingly bad wavy wira. Tan has therefore managed to get relatively short lengths the tapes into one another in order to prevent the tapes from diverging. However, this resulted in difficulties in the transition between the individual bands.

Um diesen Schwierigkeiten abzuhelfen und eine stets mittige gegenseitige Führung zwischen den Rollen des Rollen-Tragebandes und denjenigendes Porm-Rollenbancles beziehungsweise des Haltebandes zu erreichen, wird nach der Erfindung vorgeschlagen, daß das Form-Rollenband mit dem Rollen-Trageband und gegebenenfalls dem Halteband über eine Triebstockverzahnung kraftschlüssig verbunden ist. Hierbei können die Glieder der Antriebsketten des antreibenden Rollen-Tragebandes eine in den Rohren des angetriebenen Form-Rollenbandes beziehungsweise des Haltebandes kämmende Verzahnung aufweisen.To remedy these difficulties and always a central mutual Guide between the rolls of the roll carrying tape and those of the Porm roll bancles or to achieve the retaining strap is proposed according to the invention, that the form roller tape with the roller carrying tape and optionally the retaining tape is positively connected via a headstock toothing. Here the Links of the drive chains of the driving roller lanyard one in the tubes the driven form roller belt or the retaining belt meshing toothing exhibit.

Nicht mehr also werden die Rollen der Bänder lediglich durch ihre Antriebsketten geführt, wodurch die oben beschriebenen SchwierigReite entstehen, sondern die exakte Mittenführung der Rollen des Porm-Rollenbandes beziehungsweise des Haltebandes zwischen je zwei Rollen des Rollen-Tragebandes wird dadurch erreicht, aaß beide Bänder miteinander kraftschlüssig in Form einer Triebstockverzahnung verbunden sind. Dadurch ergibt sich eine vollkommen exakte Wellung der zu verformenden nassen Pappebogen und damit ein einwandfreies Endprodukt.The roles of the bands are no longer determined solely by their Drive chains guided, which creates the difficulties described above, but the exact center guidance of the rollers of the Porm roller belt respectively of the retaining strap between every two rollers of the roller carrying strap is achieved by aass both bands are positively connected to each other in the form of a rack tooth system are. This results in a completely exact corrugation of the wet to be deformed Cardboard sheet and thus a perfect end product.

Um unvermeidbare Längentoleranzen beim Durchführen der Bänder durch den Eanaltrockner auszugleichen, empfiehlt es sich außerdem, daß die Glieder der Antriebsketten des angetriebenen Form-Rollenbandes und gegebenenfalls des Haltebandes jeweils mit Spiel miteinander verbund er sind. Dadurch können sich diese Bänder einer evtl. Längenveränderung des Rollen-Tragebandes anpassen, so daß jeweils wiederum die mittige Anordnung der Rollen gewährleistet ist.In order to avoid unavoidable length tolerances when running the tapes through To compensate for the oral dryer, it is also recommended that the limbs of the Drive chains of the driven form roller belt and, if necessary, of the retaining belt each with a game he is connected to each other. This can cause these ligaments adapt to any change in length of the roller lanyard so that each time again the central arrangement of the rollers is guaranteed.

Um auch den Übergang zwischen dem Form-Rollenband und einem evtl. Halteband zu vermeiden, wird nach der Erfindung weiterhin vorgeschlagen, daß das Porm-Bollenband und das Halteband zu einem einzigen Form-Halteband zusammengefasst ist.In order to also make the transition between the form roller belt and a possibly To avoid holding strap, it is further proposed according to the invention that the Porm-Bollenband and the retaining band combined into a single form retaining band is.

Auf aer Zeichnung ist die erfindungsgemäße Einrichtung schematisch angestellt und zwar zeigen: Fig. 1 eine Anordnungsskizze, Fig. 2 ein Form-Halteband, teilweise geschnitten, und Fig. 3 die Seitenansicht eines Form-Haltebandes im Eingriff in die ein Form-Rollenband.The device according to the invention is schematically shown in the drawing employed, namely: FIG. 1 shows an arrangement sketch, FIG. 2 shows a form-retaining band, partially in section, and FIG. 3 is a side view of a form retaining band in engagement in a form roller band.

Über eine Rollenbahn 3 und Leerrollen 6 werden Pappebogen 2 in Transportrichtung 4 einer Welleinrichtung 7 zugeführt. Die welleinrichtung 7 wird gebildet durch ein unteres Rollen-Trageband 8 und einem darüber angeordneten, in aieses Rollen-Trageband (8) eingreifendes Form-Halteband 19. Diese Welleinrichtung bildet gleichzeitig den Einlauf in einen Kanaltrockner 10 und führt die gewellten Pappebogen mit einer gegenüber der Zuführgeschwindigkeit 4 etwas geringeren Geschwindigkeit 14 in beziehungsweise durch den Kanaltrockner 10.Cardboard sheets 2 are moved in the transport direction via a roller conveyor 3 and empty rollers 6 4 is fed to a shaft device 7. The wave device 7 is formed by a lower roller carrying tape 8 and one above it, in aieses roller carrying tape (8) engaging form retaining strap 19. This wave device also forms the Inlet into a tunnel dryer 10 and leads the corrugated cardboard sheet with an opposite the feed speed 4 slightly lower speed 14 in respectively through the tunnel dryer 10.

Angetrieben wird in erfindungsgemäßer Weise lediglich das Rollen-Trageband 8. Dieses Rollen-Trageband 8 nimmt das Form-Halteband19 über eine Triebstockverzahnung mit.Only the roller carrying strap is driven in the manner according to the invention 8. This roller-carrying strap 8 takes the form-holding strap 19 over a rack tooth system with.

In Fig. 3 ist in Seitenansicht der Eingriff des Form-Haltebandes 19 in das Rollen-Trageband 8 dargestellt. Das auf einer Schiene 11 geführte Rollen-Trageband 8 weist eine Triebstockverzahnung 12 der einzelnen Kettenglieder auf. In diese Triebstockverzahnung 12 greifen Rollen 13 des Form-Haltebandes 15 ein, so daß die Rohre 13 des Form-Haltebandes stets mittig zwischen den Rohren 16 des Rollen-Tragebandes 8 zu liegen kommen.In FIG. 3, the engagement of the mold retaining band 19 is shown in side view shown in the roller strap 8. The roller carrying tape guided on a rail 11 8 has a rack tooth system 12 of the individual chain links. In this rack toothing 12 engage rollers 13 of the form-retaining band 15, so that the tubes 13 of the form-retaining band always come to lie in the middle between the tubes 16 of the roller carrying strap 8.

Um eine Anpassung an Längenveränderungen des Rollen-Tragebandes 8 zu erreichen, weisen die einzelnen Glieder des Form-Haltebandes 15 gegensei-lig Spiel auf. Dies wird dadurch erreicht, daß die Befestigungsbolzen ;9 17 der einzelnen Kettenglieder einen geringzügig kleineren Durchmesser aufweisen als der lichte Durchmesser einer Buchse 18 im darauffolgenden Kettenglied. Um diese Durchmesserdifferenz d2-d1 kann sich die Antriebskette und damit auch der gegenseitige Abstand zwischen den Rollen 13 verändern, womit sich auch die Rollen 13 einer evtl. Längenänderung des Rollen-Tragebandes 8 anpassen können.In order to adapt to changes in length of the roller carrying strap 8 to achieve, the individual links of the form-retaining strap 15 have opposite one another Play on. This is achieved in that the fastening bolts; 9 17 of the individual Chain links have a slightly smaller diameter than the clear diameter one Bushing 18 in the following chain link. To this diameter difference d2-d1 can the drive chain and thus the mutual distance between the rollers 13 change, with which the rollers 13 a possible change in length of the roller carrying strap 8 can customize.
