Definitions
- the invention relates to a device for supporting the press belts on double belt presses according to the preamble of the preceding claim.
- Double belt presses are used to exert a surface pressure on plate-shaped workpieces or on material webs that are continuously guided through the machine with the supply or removal of heat to or from the pressed material.
- continuously operating double belt presses allow the pressed goods to move continuously and thus to overlap the pressing and transport process, but in particular to exert surface pressure on any length of material.
- Presses of known type work, as far as they have proven to be permanently reliable in the past, either according to the fluid cushion principle (cf. DBP 2 737 629, DE-AS 2 722 262, US Pat. No. 2,528,168) or according to the roller principle.
- Disadvantages of the fluid cushion machines are their high energy requirement at higher pressures from approximately 200 N / cm 2 and the need existing there to fully cover the working width and length with press material or to provide partially switchable cushions which are prone to failure.
- the disadvantage of the roller-mounted double belt presses is the Hertzian pressure that occurs between the support rollers and the press belts, which limits the surface pressures that can be reliably controlled to a technically uninteresting area.
- both the fluid cushion and the roller bed pressure are applied to the material to be pressed, with which an overall increased surface pressure is achieved with the safe operation of such a double belt press.
- the roller or fluid pressure can also be applied individually.
- a fluid pressure medium is used in the pressure chamber generates a pressure that acts on the rollers via the support bearing strips of the roller bed. This adds this pressure to the pressure already mechanically applied to the roller bed.
- a surface pressure acting on the press belts is also generated in the shape compensation space with the aid of a fluid pressure medium. Since the compressive force is an undirected force and acts in all directions, the pressure transferred from the roller bed to the press belt via Hertzian pressure is reduced by this pressure prevailing in the shape-compensating space, ie the press belt is relieved again. The Hertzian pressure exerted by the roller bed is thus kept smaller than the squeeze limit of the press belt, which is determined by the material used. On the other hand, however, the surface pressure prevailing in the shape-compensating space also acts on the press belt, so that the total pressure present in the shape-compensating space due to Hertzian pressure and fluid pressure medium acts on the material to be pressed.
- full-needle needle sleeves are arranged in rows offset from one another on known common axes in such a way that their radial distances are only so large that the cavities between the heating plate, support, press belt and needle sleeves have it filled by a shaped body that allows the formation of gaps of the same, small thickness between the heating plate, support, press belt and needle sleeves, into which liquid lubricant can penetrate under capillary action, but on the other hand ensures through its shape that it has the necessary turning and sliding movements not hindered between press belt and needle sleeves.
- the fluid or gaseous pressure medium and also the seals necessary for maintaining the pressure cushion can be dispensed with if the liquid lubrication is maintained by replacing the drag losses of lubricant which have arisen at the outlet of the roller bed.
- the gap height of the machine is dimensioned so that the rollers have no contact with the press belt and only the roller bed of the lower press belt absorbs any sag of the belt / press package.
- the different pressures adapted to the material to be pressed are set in the individual fluid cushions.
- the shape compensation space comprising the entire roller bed and the pressure chamber are divided into individual and mutually independent pressurized fluid cushions that are sealed against one another.
- the needle rollers 2 which are usually arranged in rows parallel to the feed direction of the press belts 6 between support bearing strips 1 on support shafts 12, are thus half a roller width apart offset so that every second support bearing bore 5 is replaced by an opening 3 which is larger by the capillary gap height 4 than the diameter of the needle roller 2.
- the bearing bore 5 and opening 3 are longitudinally offset from one another in the tape feed direction, so that Needle rollers 2 installed between two bearing bores 5 are offset in the transverse direction.
- the cavity between two needle rollers 2 is filled by a filler 11 in such a way that to the adjacent needle rollers 2, the heating plate 13 and the support bearing strips attached therein 1 gaps with a suitably dimensioned capillary gap height 4 are formed, into which liquid or semi-liquid lubricants 8 are drawn in under capillary action.
- liquid or semi-liquid lubricant 8 is now added to the belt or roller surfaces of the first row of rollers at the entry of the press belts 6 into the roller bed 7, it is distributed across the roller gap 9 and the remaining excess of two adjacent needle rollers 2 becomes fed through the support bearing gap 10 in the middle of the next following needle roller 2 in the direction of tape feed, where the process described is repeated.
- an additional shape compensation space 19 and a pressure chamber 15 with seals 16 are provided over the entire roller bed 7 and can be acted upon by fluid pressure media.
- the shape compensation space 19 is limited at the top by the heating plate 13 and at the bottom by the press belt 6.
- the pressure chamber 15 is bounded at the bottom by the heating plate 13 and at the top by the closure 18. This makes it possible, additionally or optionally, to exert a surface pressure on the press belt 6 in addition to the Hertzian pressure.

Mit der erfindungsgemässen Vorrichtung wird der Bereich betriebssicher beherrschbarer Flächendrucke bei Doppelbandpressen erheblich erweitert, ohne auf die Vorteile des Fluidkissenprinzips und der Rollenbettlagerung zu verzichten und die Möglichkeit eines isochoren, isobaren und kombinierten Betriebs bei der Herstellung von Pressgut aller Art eröffnet.With the device according to the invention, the area of reliably controllable surface pressures in double belt presses is considerably expanded, without sacrificing the advantages of the fluid cushion principle and roller bed mounting, and the possibility of isochoric, isobaric and combined operation in the production of all types of pressed material.
Description
Gegenstand der Erfindung ist eine Vorrichtung zur Stützung der Pressbänder an Doppelbandpressen gemäss dem Oberbegriff des vorstehenden Patentanspruchs.The invention relates to a device for supporting the press belts on double belt presses according to the preamble of the preceding claim.
Doppelbandpressen dienen zur Ausübung eines Flächendrucks auf plattenförmige Werkstücke oder auf kontinuierlich durch die Maschine geführte Materialbahnen unter Zu- oder Abfuhr von Wärme an das oder aus dem Pressgut.Double belt presses are used to exert a surface pressure on plate-shaped workpieces or on material webs that are continuously guided through the machine with the supply or removal of heat to or from the pressed material.
Solche kontinuierlich arbeitenden Doppelbandpressen erlauben im Gegensatz zu den diskontinuierlich arbeitenden Plattenpressen die stetige Fortbewegung des Pressgutes und damit die Überlagerung von Press- und Transportvorgang, besonders jedoch die Ausübung von Flächendruck auf eine beliebig lange Materialbahn.In contrast to discontinuously operating plate presses, such continuously operating double belt presses allow the pressed goods to move continuously and thus to overlap the pressing and transport process, but in particular to exert surface pressure on any length of material.
Pressen bekannter Art arbeiten, soweit sie sich in der Vergangenheit als dauerhaft betriebssicher erwiesen haben, entweder nach dem Fluidkissenprinzip (vgl. DBP 2 737 629, DE-AS 2 722 262, US-PS 2 528 168) oder nach dem Rollenprinzip. Nachteil der Fluidkissemaschinen ist deren hoher Energiebedarf bei höheren Drücken ab etwa 200 N/cm2 sowie die dort bestehende Notwendigkeit, die Arbeitsbreite und -länge voll mit Pressgut auszulegen oder störungsanfällige teilabschaltbare Kissen vorzusehen. Nachteil der rollengelagerten Doppelbandpressen ist die zwischen den Stützrollen und den Pressbändern auftretende Hertzsche Pressung, die die betriebssicher beherrschbaren Flächendrücke auf einen technisch wenig interessanten Bereich begrenzt.Presses of known type work, as far as they have proven to be permanently reliable in the past, either according to the fluid cushion principle (cf. DBP 2 737 629, DE-AS 2 722 262, US Pat. No. 2,528,168) or according to the roller principle. Disadvantages of the fluid cushion machines are their high energy requirement at higher pressures from approximately 200 N / cm 2 and the need existing there to fully cover the working width and length with press material or to provide partially switchable cushions which are prone to failure. The disadvantage of the roller-mounted double belt presses is the Hertzian pressure that occurs between the support rollers and the press belts, which limits the surface pressures that can be reliably controlled to a technically uninteresting area.
Nachteilig ist ferner, dass bekannt gewordene Fluidkissen-Doppelbandpressen nur isobaren Pressbetrieb ermöglichen, während rollengestützte Maschinen mit fest eingebautem Rollenbett nur isochoren Betrieb gestatten.Another disadvantage is that known fluid cushion double belt presses only allow isobaric press operation, while roller-based machines with a permanently installed roller bed only allow isochoric operation.
Es hat sich herausgestellt, dass man die Vorrichtung gemäss Patentanmeldung P 31 35 031.3 - 14 verbessern, d.h. den Bereich der betriebssicher beherrschbaren Flächendrücke bei Doppelbandpressen wesentlich erweitern kann, ohne die Vorteile sowohl des Fluidkissenprinzips als auch des rollengelagerten Prinzips aufzugeben und eine Presse vorzuschlagen, die wahlweise und unabhängig voneinander durch einfache Schaltvorgänge sowohl isochoren oder isobaren als auch kombinierten Betrieb, der gleichzeitig isochor und isobar ist, gestattet und die dabei die für die jeweilige isochore, isobare oder kombinierte Bearbeitung des Pressgutes erforderlichen geometrischen Eigenschaften der Maschinenstruktur in einer Bauform bereithält, die Maschine für universellen Gebrauch geeignet zu machen.It has been found that the device according to patent application P 31 35 031.3 - 14 can be improved, i.e. can significantly expand the range of reliably controllable surface pressures in double belt presses without giving up the advantages of both the fluid cushion principle and the roller-mounted principle and proposing a press that can be operated either isochorically or isobarically as well as combined, independently of one another by simple switching processes, which is isochoric and combined at the same time isobar is permitted, and which provides the geometric properties of the machine structure required for the respective isochoric, isobaric or combined processing of the pressed material in a design to make the machine suitable for universal use.
Es wurde nun gefunden, dass man durch eine besondere Ausgestaltung des Rollenbettes als Formausgleichsraum und Anordnung einer zusätzlichen Druckkammer gemäss dem Kennzeichen des Patentanspruchs die vorgenannte Aufgabe lösen kann.It has now been found that the above-mentioned object can be achieved by a special configuration of the roller bed as a shape compensation space and arrangement of an additional pressure chamber according to the characterizing part of the patent claim.
Die mit der Erfindung erzielbaren Vorteile bestehen darin, dass durch erfindungsgemässe Kombination teilweise bekannter Lösungsmittel beider Funktionsprinzipien, auf das Pressgut sowohl des Fluidkissen- als auch des Rollenbettdrucks aufgebracht werden, womit ein insgesamt erhöhter Flächendruck bei sicherem Betrieb einer solchermassen ausgestalteten Doppelbandpresse erreicht wird. Zum wahlweisen isochoren oder isobaren Betrieb der Doppelbandpresse können der Rollen- oder der Fluiddruck auch einzeln aufgebracht werden.The advantages that can be achieved with the invention are that by combining, according to the invention, partially known solvents of both functional principles, both the fluid cushion and the roller bed pressure are applied to the material to be pressed, with which an overall increased surface pressure is achieved with the safe operation of such a double belt press. For optional isochoric or isobaric operation of the double belt press, the roller or fluid pressure can also be applied individually.
In der Druckkammer wird mit Hilfe eines fluiden Druckmittels ein Druck erzeugt, der über die Stützlagerleisten des Rollenbettes auf die Rollen wirkt. Dadurch addiert sich dieser Druck zum bereits mechanisch auf das Rollenbett aufgebrachten Druck. In dem Formausgleichsraum wird ebenfalls mit Hilfe eines fluiden Druckmittels ein auf die Pressbänder wirkender Flächendruck erzeugt. Da die Druckkraft eine ungerichtete Kraft ist und in alle Richtungen wirkt, vermindert sich der vom Rollenbett auf das Pressband über Hertzsche Pressung übertragene Druck um diesen in dem Formausgleichsraum herrschenden Druck, d.h. das Pressband wird wieder entlastet. Damit wird die durch das Rollenbett ausgeübte Hertzsche Pressung kleiner als die Quetschgrenze des Pressbandes, die vom verwendeten Material bestimmt wird, gehalten. Andererseits wirkt aber der im Formausgleichsraum herrschende Flächendruck auch auf das Pressband, so dass auf das Pressgut insgesamt die durch hertzsche Pressung und fluiden Druckmittel in den Formausgleichsraum vorhandene Drucksumme wirkt.A fluid pressure medium is used in the pressure chamber generates a pressure that acts on the rollers via the support bearing strips of the roller bed. This adds this pressure to the pressure already mechanically applied to the roller bed. A surface pressure acting on the press belts is also generated in the shape compensation space with the aid of a fluid pressure medium. Since the compressive force is an undirected force and acts in all directions, the pressure transferred from the roller bed to the press belt via Hertzian pressure is reduced by this pressure prevailing in the shape-compensating space, ie the press belt is relieved again. The Hertzian pressure exerted by the roller bed is thus kept smaller than the squeeze limit of the press belt, which is determined by the material used. On the other hand, however, the surface pressure prevailing in the shape-compensating space also acts on the press belt, so that the total pressure present in the shape-compensating space due to Hertzian pressure and fluid pressure medium acts on the material to be pressed.
Um die Schmierung aller gegeneinander gleitenden oder aufeinander abrollenden Elemente des Rollenbettes sicherzustellen, werden vollnadelige Nadelhülsen auf an sich bekannten gemeinsamen Achsen reihenweise gegeneinander versetzt so angeordnet, dass ihre radialen Abstände lediglich so gross sind, dass sich die Hohlräume zwischen Heizplatte, Stütze, Pressband und Nadelhülsen durch einen Formkörper ausfüllen lassen, der einerseits die Ausbildung von Spalten gleicher, geringer Dicke zwischen Heizplatte, Stütze, Pressband und Nadelhülsen zulässt, in die flüssiges Schmiermittel unter Kapillarwirkung eindringen kann, andererseits jedoch durch seine Formgebung sicherstellt, dass er die notwendigen Dreh- und Gleitbewegungen zwischen Pressband und Nadelhülsen nicht behindert.In order to ensure the lubrication of all elements of the roller bed that slide or roll against one another, full-needle needle sleeves are arranged in rows offset from one another on known common axes in such a way that their radial distances are only so large that the cavities between the heating plate, support, press belt and needle sleeves have it filled by a shaped body that allows the formation of gaps of the same, small thickness between the heating plate, support, press belt and needle sleeves, into which liquid lubricant can penetrate under capillary action, but on the other hand ensures through its shape that it has the necessary turning and sliding movements not hindered between press belt and needle sleeves.
Wird eine Maschine mit Rollenbett innerhalb eines beispielsweise nach DBP 2 722 197 bzw. 2 907 087 ausgebildeten Fluidkissens mit Öl als Druckmittel betrieben, so kann die Anordnung von Füllkörpern entfallen, da das Druckmittel die Schmierung sicherstellt.For example, if a machine with a roller bed is within a DBP 2 722 197 or 2 907 087 designed fluid cushion operated with oil as pressure medium, the arrangement of packing elements can be omitted, since the pressure medium ensures lubrication.
Soll die erfindungsgemässe Maschine nur isochor betrieben werden, so kann auf das fluide oder gasförmige Druckmittel und auch auf die zur Aufrechterhaltung des Druckkissens notwendigen Dichtungen verzichtet werden, wenn durch Ersatz der am Ausgang des Rollenbettes aufgegangenen Schleppverluste an Schmiermittel die flüssige Schmierung aufrechterhalten wird.If the machine according to the invention is only to be operated isochorously, then the fluid or gaseous pressure medium and also the seals necessary for maintaining the pressure cushion can be dispensed with if the liquid lubrication is maintained by replacing the drag losses of lubricant which have arisen at the outlet of the roller bed.
Für rein isobaren Betrieb wird die Spalthöhe der Maschine so bemessen, dass die Rollen keinen Kontakt haben mit dem Pressband und lediglich das Rollenbett des unteren Pressbandes einen eventuellen Durchhang des Band-Pressgut-Paketes aufnimmt.For purely isobaric operation, the gap height of the machine is dimensioned so that the rollers have no contact with the press belt and only the roller bed of the lower press belt absorbs any sag of the belt / press package.
Erfordert das Pressgut z. B. Spänevlies zur Herstellung von Spanplatten oder Glasfasergewebematte mit Kupferfolie zur Herstellung von Leiterplatten-Schichtstoff kombinierten isochor-isobaren Betrieb, so werden in den einzelnen Fluidkissen die dem Pressgut angepassten unterschiedlichen Drücke eingestellt. Dazu ist der das gesamte Rollenbett umfassende Formausgleichsraum und die Druckkammer in einzelne und voneinander unabhängige mit Druck beaufschlagbare, gegeneinander abgedichtete Fluidkissen eingeteilt.Requires the pressing material z. B. chip fleece for the production of chipboard or fiberglass mat with copper foil for the production of printed circuit board laminate combined isochor-isobar operation, the different pressures adapted to the material to be pressed are set in the individual fluid cushions. For this purpose, the shape compensation space comprising the entire roller bed and the pressure chamber are divided into individual and mutually independent pressurized fluid cushions that are sealed against one another.
In der Zeichnung ist eine Ausführungsform der Erfindung in seitlicher Schnittansicht dargestellt.In the drawing, an embodiment of the invention is shown in a side sectional view.
Die üblicherweise in Reihen parallel zur Vorschubrichtung der Pressbänder 6 zwischen Stützlagerleisten 1 auf Stützwellen 12 angeordneten Nadelrollen 2 sind dadurch um eine halbe Rollenbreite gegeneinander so versetzt, dass jede zweite Stützlagerbohrung 5 durch einen Durchbruch 3 ersetzt ist, der um die Kapillarspalthöhe 4 grösser bemessen ist als der Durchmesser der Nadelrolle 2. An in Querrichtung benachbarten Stützlagerleisten 1 sind Lagerbohrung 5 und Durchbruch 3 in Bandvorschubrichtung längs gegeneinander versetzt, so dass jeweils zwischen zwei Lagerbohrungen 5 eingebaute Nadelrollen 2 in Querrichtung versetzt liegen. Der Hohlraum zwischen zwei Nadelrollen 2 wird von einem Füllkörper 11 so ausgefüllt, dass zu den benachbarten Nadelrollen 2, der Heizplatte 13 und den darin befestigten Stützlagerleisten 1 Spalte mit einer geeignet bemessenen Kapillarspalthöhe 4 entstehen, in die flüssige oder halbflüssige Schmierstoffe 8 unter Kapillarwirkung einziehen.The
Wird nun am Eintritt der Pressbänder 6 in das Rollenbett 7 flüssiger oder halbflüssiger Schmierstoff 8 auf die Band- oder auch auf die Rollenoberflächen der ersten Rollenreihe gegeben, so wird er über den Wälzspalt 9 quer verteilt und der verbleibende Überschuss von je zwei benachbarten Nadelrollen 2 wird durch die Stützlagerlücke 10 mittig der in Bandvorschubrichtung nächstfolgenden Nadelrol.le 2 zugeführt, wo sich der beschriebene Vorgang wiederholt. Auf der dem Pressband 6 abgewandten Seite ist über das gesamte Rollenbett 7 hinweg ein zusätzlicher, mit fluiden Druckmitteln beaufschlagbarer Formausgleichsraum 19 und eine Druckkammer 15 mit Dichtungen 16 vorgesehen.If liquid or
Der Formausgleichsraum 19 wird nach oben durch die Heizplatte 13 und nach unten durch das Pressband 6 begrenzt. Die Druckkammer 15 wird nach unten durch die Heizplatte 13 und nach oben durch den Abschluss 18 begrenzt. Damit wird ermöglicht, zusätzlich oder wahlweise zur Hertzschen Pressung einen Flächendruck auf das Pressband 6 auszuüben.The
Das aus dem Formausgleichsraum austretende fluide Druckmittel wird mit Hilfe der Dichtungen 14 vom Pressband abgestreift und angesammelt. Damit es nicht das Pressgut beeinträchtigen kann, sind in dem die Formausgleichskammer abschliessenden Rollenbett 7 am Unterdruck oder Vakuum aneschlossene Bohrungen 17 eingebracht, durch die das ausgetretene Druckmittel abgeführt wird.The fluid pressure medium emerging from the shape-compensating space is stripped off and collected from the press belt with the aid of the
