Description

Die Erfindung betrifft eine Maschine zur Herstellung einer Wellpappebahn sowie ein Verfahren zur Kalibrierung des Beleimungsspaltes einer solchen Maschine.The invention relates to a machine for producing a corrugated cardboard web and a method for calibrating the gluing gap of such Machine.

Es ist durch offenkundige Vorbenutzung zur Einstellung der Breite des Beleimungsspaltes zwischen einer Riffelwalze und einer Leimauftragswalze in einer Wellpappemaschine bekannt, daß eine Bedienungsperson von Hand ein sogenanntes Spleißband mit vorgegebener Dicke zwischen die mit einer Wellbahn belegte Riffelwalze und die Leimauftragswalze hält. Anschließend wird der Abstand zwischen der Leimauftragswalze und der Riffelwalze reduziert. Dies geschieht bei rotierender Riffelwalze und rotierender Leimauftragswalze. Die Breite des Beleimungsspaltes wird solange reduziert, bis das Spleißband durch die rotierenden Walzen mitgenommen wird. Der Beleimungsspalt ist dann auf die Dicke des Spleißbandes eingestellt. Diese Art der Einstellung des Beleimungsspaltes hat jedoch den Nachteil, daß die Einstellung aufwendig ist und nicht automatisch erfolgen kann. Ferner besteht die Gefahr, daß die Hand, mit der die Bedienungsperson das Spleißband hält, in den Beleimungsspalt gezogen und verletzt wird.It is due to public prior use to adjust the width of the Gluing gap between a corrugating roll and a glue applicator roll in a corrugated board machine that an operator of Hand a so-called splicing tape with a given thickness between the with a corrugated web occupied corrugating roller and the glue roller holds. Subsequently becomes the distance between the glue applicator roller and the corrugating roller reduced. This happens with rotating corrugating roller and rotating Glue spreader. The width of the gluing gap is as long reduced until the splicing tape was taken by the rotating rollers becomes. The gluing gap is then adjusted to the thickness of the splicing tape. However, this type of setting the Beleimungsspaltes has the Disadvantage that the setting is complicated and not done automatically can. Furthermore, there is a risk that the hand with which the operator holds the splice tape, pulls it into the gluing nip and gets injured.

Aus der DE 197 15 174 A1 ist eine Maschine zur Herstellung einer Wellpappebahn bekannt. Die Leimauftragswalze wird unmittelbar gegen die einen Teil der Riffelwalze umschlingende Wellbahn gedrückt. Ein Beleimungsspalt zwischen der Wellbahn und der Mantelfläche der Beleimungswalze ist nicht vorhanden. Zur Einstellung einer vorgegebenen Anpreßkraft zwischen Beleimungswalze und Wellbahn ist eine Kraftmeßeinheit sowie eine Einrichtung zur Veränderung des Abstandes zwischen Riffelwalze und Leimauftragswalze vorgesehen. Nachteilig an dieser Anordnung ist, dass die Leimauftragswalze mit einer vorgegebenen Kraft gegen die Riffelwalze drückt, wodurch die Leimauftragswalze möglicherweise beschädigt wird.From DE 197 15 174 A1 is a machine for producing a corrugated web known. The glue roller is directly against the pressed a part of the corrugating roll encircling corrugated web. A gluing gap between the corrugated web and the lateral surface of the gluing roller is not present. For setting a predetermined contact pressure between Beleimungswalze and corrugated web is a Kraftmeßeinheit as well a device for changing the distance between corrugating roller and Gluing roller provided. The disadvantage of this arrangement is that the glue application roller with a predetermined force against the corrugating roller pushes, which may damage the glue applicator roll.

Aus der US 5,415,720 ist eine Maschine zur Herstellung einer Wellpappebahn bekannt, die eine gelagerte Riffelwalze, eine Leimauftrags-Einrichtung mit einer gelagerten Leimauftragswalze, einen Beleimungsspalt und eine Kalibrier-Einrichtung zur Einstellung der Breite des Beleimungsspaltes umfasst. Die Breite des Beleimungsspaltes zwischen der Leimauftragswalze und der Riffelwalze wird mittels eines Wirbelstrom-Abstandssensors erfasst. Der Wirbelstrom-Abstandssensor ist an einem Gestell angebracht, an dem die Leimauftragswalze drehbar gelagert ist und das relativ zur Riffelwalze verschiebbar ist. Die Einstellung des Beleimungsspaltes erfolgt mittels einer Regeleinrichtung, die einen Verstellantrieb derart ansteuert, dass ein am Gestell angeordneter verstellbarer Anschlag, der sich gegen die gelagerte Riffelwalze abstützt, den gewünschten Abstand herstellt. Eine derartige Anordnung weist die Nachteile auf, dass die Erfassung der Breite des Beleimungsspaltes mittels des Wirbelstrom-Abstandssensors sowie die Einstellung der Spaltbreite über den verschiebbaren Anschlag aufwändig und empfindlich gegenüber Verschmutzungen ist.From US 5,415,720 is a machine for producing a corrugated web known that a stored corrugating roller, a glue application device with a mounted glue applicator roll, a gluing nip and a calibration device for adjusting the width of the gluing gap includes. The width of the gluing gap between the Glue applicator roll and the corrugating roll is by means of an eddy current distance sensor detected. The eddy current distance sensor is on one Mounted frame on which the glue applicator roll is rotatably mounted and which is displaceable relative to the corrugating roll. The setting of the gluing gap takes place by means of a control device, which is an adjustment controls such that an adjustable stop arranged on the frame, which is supported against the mounted corrugating roll, the desired Distance is established. Such an arrangement has the disadvantages that the detection of the width of the gluing gap by means of the eddy current distance sensor as well as the adjustment of the gap width over the displaceable Stop complex and sensitive to contamination is.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Maschine zur Herstellung von Wellpappe bereitzustellen, bei der die Einstellung des Beleimungsspaltes möglichst einfach und automatisch erfolgen kann.The invention is therefore based on the object, a machine for manufacturing of corrugated board, in which the setting of the gluing gap as simple and automatic as possible.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 sowie durch das Verfahren gemäß Anspruch 10 gelöst. Der Kern der Erfindung besteht darin, das Lager der Leimauftragswalze gegen das Lager der Riffelwalze mit einer vorgegebenen Kraft zu drücken und die Lageranpress-Kraft zwischen beiden Lagern zu messen. Der Abstand zwischen beiden Lagern wird anschließend solange reduziert, bis die Leimauftragswalze in Kontakt mit der Riffelwalze kommt. Dies wird dadurch detektiert, dass die Langeranpress-Kraft abfällt, da ein Teil der Andrück-Kraft über die Walzen übertragen wird.The object is achieved by the features of claim 1 and by the A method according to claim 10 solved. The core of the invention exists in it, the bearing of the glue roller against the bearing of the corrugating roller to press with a given force and the bearing pressure force between to measure both camps. The distance between both camps becomes then reduced until the glue application roller in contact with the corrugating roll comes. This is detected by the fact that the Langeranpress force drops as part of the pressing force transmitted through the rollers becomes.

Diese umfaßt im Bereich beider Enden der Leimauftragswalze 22 eine Andrück-Einheit 38, die eine senkrecht zur Achse 28 verschiebbare Kolbenstange 39 aufweist, die mit einer Andrück-Kraft A gegen das in einer Schiebeführung 40 senkrecht zur Achse 28 und in der durch die Achsen 7 und 28 aufgespannten Ebene verschiebbar geführte Lagergehäuse 26 drückt. Zwischen den Lagergehäusen 26 und 32 ist zueinander benachbart eine als Kraftmeßdose ausgebildete Kraftmeß-Einheit 41 und eine Stell-Einheit 42 zur Einstellung des Lager-Abstandes L zwischen den Lagergehäusen 26 und 32 vorgesehen.

Fig. 3 zeigt die spiegelbildliche Darstellung zu Fig. 2, wobei die korrespondierenden Elemente dieselben Bezugszeichen wie in Fig. 2, jedoch mit einem hochgesetzten Strich erhalten.To adjust the width B of the gluing gap 30 is a calibration device 37 provided. This includes in the region of both ends of the Glue applicator roller 22 a pressing unit 38, which is a perpendicular to Axis 28 displaceable piston rod 39 which, with a pressing force A against that in a sliding guide 40 perpendicular to the axis 28 and slidably guided in the plane defined by the axes 7 and 28 plane Bearing housing 26 presses.

Im folgenden wird zunächst die Wirkungsweise der Maschine im Normalbetrieb beschrieben. In den Berührungsbereich 10 läuft eine Papierbahn 50 ein, die durch die Riffelungen 8, 9 zu einer Wellbahn 51 wird. Die Wellbahn 51 weist Wellenspitzen 52 auf, die in der Leimauftrags-Einrichtung 13 mit Leim versehen werden. Die übrigen Bereiche der Wellbahn 51 werden nicht beleimt. Über die Umlenkwalze 16 wird eine Kaschierbahn 53 zugeführt, die ebenfalls aus Papier besteht und die gleiche Breite hat wie die Papierbahn 50. Die Kaschierbahn 53 wird gegen die Außenseite 54 des Anpreßbandes 17 eingeführt und in dem Bereich, in dem das Anpreßband 17 gegen die Riffelwalze 3 anliegt, gegen die Wellenspitzen 52 gedrückt und mit diesen verbunden. Anschließend wird die Einheit aus Wellbahn 51 und Kaschierbahn 53 um die Umlenkwalze 15 geführt.The following is the operation of the machine in normal operation described. In the contact region 10, a paper web 50 runs which becomes a corrugated web 51 through the corrugations 8, 9. The corrugated railway 51 has shaft tips 52 which are in the glue application device 13 be provided with glue. The remaining areas of the corrugated web 51 become not glued. About the guide roller 16 is a laminating 53rd fed, which is also made of paper and has the same width as the paper web 50. The liner 53 is against the outside 54 of the Anpreßbandes 17 introduced and in the area in which the pressure belt 17 abuts against the corrugating roller 3, pressed against the shaft tips 52 and connected with them. Subsequently, the unit of corrugated web 51 and laminating 53 guided around the guide roller 15.

Im folgenden wird die Kalibrierung der Breite B des Beleimungsspalts 30 beschrieben. Anfänglich sind die Riffelwalze 3 und die Leimauftragswalze 22 voneinander um mehr als die durch die Kalibrierung einzustellende Breite entfernt. Eine Andrück-Einheit 38 drückt an einem Ende der Leimauftragswalze 22 das Lagergehäuse 26 gegen das Lagergehäuse 32 mit einer Andrück-Kraft A. Weder die Leimauftragswalze 22 noch der Anlaufring 36a befinden sich in Kontakt mit der Riffelwalze 3. Die in der Kraftmeß-Einheit 41 gemessene Lager-Anpreß-Kraft P entspricht im wesentlichen der Andrück-Kraft A. Anschließend wird durch den Spindelmotor 45 der Schiebe-Keil 44 in Figur 2 nach links verschoben, wodurch sich der Lager-Abstand L reduziert. Dies geschieht solange, bis der Anlaufring 36a in Kontakt mit der Riffelwalze 3 kommt. In diesem Augenblick verzweigt sich der Pfad der Andrück-Kraft A, da nun ein Teil der Andrück-Kraft A über den Anlaufring 36a auf die Riffelwalze übertragen wird und ein anderer Teil weiterhin über das Lagergehäuse 26 und die Kraftmeß-Einheit 41 auf das Lager 32 übertragen wird. Deshalb fällt die in der Kraftmeß-Einheit 41 gemessene Lager-Anpreß-Kraft P ab, wodurch das Anliegen des Anlaufrings 36a an der Riffelwalze 3 detektiert wird. Der Außendurchmesser DA des Anlaufrings 36a ist so gewählt, daß relativ zum sonstigen Außendurchmesser DL der Leimauftragswalze 22 gilt: (DA - DL) /2 entspricht der Breite des kalibrierten Beleimungsspalts 30. Das Kalibrierverfahren wird an beiden Enden der Leimauftragswalze 22 durchgeführt. Durch die Steuer-Einheit 49 kann der Kalibriervorgang vollkommen automatisch an beiden Enden der Leimauftragswalze 22 durchgeführt werden. Durch den gegenüber der Leimauftragswalze 22 vorstehenden Anlaufring 36a wird vermieden, daß die Leimauftragswalze 22 mit der Riffelwalze 3 in Berührung kommt, wodurch die Oberfläche der Leimauftragswalze 22 beschädigt werden könnte. Der Überstand (DA-DL) /2 des Anlaufrings 36a gegenüber der Leimauftragswalze 22 ist so gewählt, daß er kleiner ist als die kleinste zu verarbeitende Dicke der Wellbahn 51.In the following, the calibration of the width B of the gluing gap 30 will be described. Initially, the corrugating roller 3 and the glue applicator roller 22 are spaced from each other by more than the width to be set by the calibration. A pressing unit 38 presses at one end of the glue application roller 22, the bearing housing 26 against the bearing housing 32 with a pressing force A. Neither the glue applicator roller 22 nor the stop ring 36a are in contact with the corrugating roller 3. The in the force measuring unit 41st measured bearing pressure force P corresponds substantially to the pressing force A. Subsequently, the sliding wedge 44 is shifted in Figure 2 to the left by the spindle motor 45, whereby the bearing distance L is reduced. This happens until the stop ring 36a comes into contact with the corrugating roller 3. At this moment, the path of the pressing force A branches, since now part of the pressing force A is transmitted to the corrugating roller via the stop ring 36a and another part continues to be transmitted to the bearing 32 via the bearing housing 26 and the force measuring unit 41 is transmitted. Therefore, the bearing force P measured in the force measuring unit 41 drops, whereby the abutment of the stop ring 36a on the corrugating roller 3 is detected. The outer diameter D A of the stop ring 36 a is selected so that relative to the other outer diameter D L of the glue applicator roller 22 applies: (D A - D L ) / 2 corresponds to the width of the calibrated Beleimungsspalts 30. The calibration process is performed at both ends of the glue applicator roll 22 , By the control unit 49, the calibration process can be performed completely automatically at both ends of the glue application roller 22. By the opposite of the glue application roller 22 projecting stop ring 36a is avoided that the glue application roller 22 comes into contact with the corrugating roller 3, whereby the surface of the glue application roller 22 could be damaged. The projection (D A -D L ) / 2 of the stop ring 36 a relative to the glue application roller 22 is selected so that it is smaller than the smallest thickness of the corrugated web 51 to be processed.

Nach der Kalibrierung des Beleimungsspalts 30 wird die Leimauftragswalze 22 wieder geringfügig von der Riffelwalze 3 abgehoben. Der so eingestellte Beleimungsspalt 30 weist eine bekannte Breite auf, die sich aus der Breite des kalibrierten Beleimungsspaltes 30 sowie der Höhe, um die die Leimauftragswalze 22 abgehoben wurde, ergibt. Diese Höhe kann durch den Wirbelstromsensor 47 gemessen werden. Der Beleimungsspalt 30 wird so eingestellt, daß seine Breite der Dicke der Wellbahn 51 zuzüglich eines vorgegebenen Schlupfs, der zwischen 0,01 mm und 0,03 mm, insbesondere 0,02 mm, liegt, entspricht. Während des Betriebs werden Änderungen der Spaltbreite B, die z. B. durch thermische Ausdehnung entstehen können, durch den Wirbelstrom-Sensor 47 gemessen und über die Steuer-Einheit 49 und die Stell-Einheit 42 automatisch ausgeglichen.After the calibration of the gluing gap 30, the glue application roller 22 again lifted slightly from the corrugating roller 3. The so set Glueing gap 30 has a known width, resulting from the Width of the calibrated gluing gap 30 and the height by which the Glue applicator roll 22 was lifted results. This height can be through the eddy current sensor 47 are measured. The gluing gap 30 becomes adjusted so that its width of the thickness of the corrugated web 51 plus one predetermined slip between 0.01 mm and 0.03 mm, in particular 0.02 mm, is equal to. During operation, changes to the Gap width B, the z. B. can arise due to thermal expansion, measured by the eddy current sensor 47 and the control unit 49th and the actuator 42 automatically compensated.

Es ist möglich, an der Leimauftragswalze 22 keine Anlaufringe 36a vorzusehen. In diesem Fall erfolgt die Zustellung der Leimauftragswalze 22 unmittelbar gegen die die Riffelwalze 3 teilweise umschlingende Wellbahn 51. Dies ist besonders bei Papierbahnen 50 äußerst geringer Dicke von Bedeutung, da in diesem Fall der Anlaufring 36a kaum meßbar gegenüber der Leimauftragswalze 22 hervorstehen müßte.It is possible to provide no contact rings 36a on the glue application roller 22. In this case, the delivery of the glue application roller 22 takes place immediately against the corrugating roller 3 partially wrapped corrugated web 51. This is particularly important with paper webs 50 of extremely small thickness, in this case, the stop ring 36a hardly measurable against the Glue applicator roller 22 would have to stand out.

Gerade die vorstehend angesprochene Lösung, bei der die Leimauftragswalze 22 unmittelbar gegen die die Riffelwalze 3 teilweise umschlingende Wellbahn 51 zugestellt wird, ermöglicht es, gleichermaßen in einem Durchgang die Kalibrierung der Leimauftragswalze 22 und deren Einstellung in einem durchgehenden Vorgang vorzunehmen. Hierzu wird nach dem Kontakt zwischen Leimauftragswalze 22 und Wellbahn 51 die Leimauftragswalze 22 wieder geringfügig von der Wellbahn 51 abgehoben, und zwar um einen Betrag von 0,01 bis 0,03 mm bevorzugt etwa 0,02 mm.Especially the above-mentioned solution, in which the glue applicator roll 22 directly against the corrugating roller 3 partially wrapped Wellbahn 51 is delivered, it allows, alike in one Pass the calibration of the glue applicator roll 22 and its setting in a continuous process. This is after the contact between glue application roller 22 and corrugated web 51, the glue application roller 22 again slightly lifted from the corrugated web 51, and although by an amount of 0.01 to 0.03 mm, preferably about 0.02 mm.

Während der Beleimung wird die Leimauftragswalze 22 in allen Anwendungsfällen gegenüber der Riffelwalze 3 und damit gegenüber der Wellbahn 51 mit Schlupf angetrieben, und zwar mit einer Umfangsgeschwindigkeit die 1 bis 10 % niedriger ist; die Leimauftragswalze 22 läuft also gegenüber der Wellbahn 51 nach.During gluing, the glue application roller 22 is in all applications opposite the corrugating roller 3 and thus opposite the corrugated web 51 driven with slip, and with a peripheral speed which is 1 to 10% lower; the glue application roller 22 is running towards the corrugated web 51 after.
