Definitions
- the invention relates to a device for adjusting the knife gap on drum shears, the knife drums of which are seated firmly on a pair of support shafts with helical toothed drive gears and have longitudinal recesses for receiving knife blocks in which these can be clamped with the aid of fastening elements which can be pressurized and act on clamping wedges.
- the setting of the knife gap has so far been carried out in such a way that one of the helical drive gearwheels on its seat on the journal of the supporting shaft is axially displaced with the aid of an actuating device and, due to the radial component of the supporting force on the counter teeth of the other helical drive gear causes a relative rotational displacement of the knife drum relative to the other knife drum, with which the width of the knife gap of the knife blocks of both drums can be adjusted.
- the device has the main disadvantage that the drive gear on the shaft journal of the wheel shaft of the knife drum are arranged in a rotationally fixed but axially displaceable manner, and that this displaceability has to be canceled again during the cutting operation of the scissors, that is to say blocked. This necessity required considerable technical effort, namely Eg axially parallel in the grooves between the support shaft journal and drive gear adjustable wedges with axial locking elements and a sliding device placed on the end face of the pin for the wedges.
- Such a device for axially displacing a support shaft is not suitable for adjusting the knife gap in the generic drum shears because the cutting edges of the knife blocks are all convex to the outside in an arcuate manner and therefore when one of the knife drums is axially displaced together with the knife block sitting on the drum Cutting symmetry between the knife block of one and the other knife drum is disturbed, making cutting impossible (DE-AS 2037270).
- the device Starting from a known device for fastening the knife blocks in longitudinal recesses of the circumference of the knife drums with the aid of pressurizable fasteners which act on clamping wedges and which, for example, allow the pressurization of the fasteners to be released by hydraulic counterpressure and thus make the knife blocks displaceable in the longitudinal recesses the task, the device to improve the knife gap on the generic drum shears so that the disadvantages of the complex devices for moving a drive gear on the support shaft and its blocking are avoided and the axial position of both knife blocks zue nander remains unchanged during the setting process of the knife gap.
- This object is achieved by holding stops arranged in the supporting frame of the drum shears and fixing the cutter bars during an axial displacement on one of the supporting shafts with cutter drum and drive gear wheel relative to the other in their position in the longitudinal recesses of the cutter drum.
- these holding stops can have stop pieces which can be moved in and out in the area of the end faces of the knife blocks.
- the holding stops hold the knife bar in the longitudinal recess of the knife drum to be adjusted by axial displacement during the displacement process in its original position relative to the knife bar of the other, not displaced knife drum, so that the position of the cutting edges of both knives remains unchanged transversely to the radial one.
- the fastening elements of the clamping wedges are again subjected to pressure and the holding stops are moved out of the area of the cutter bars.
- the two knife drums 1 and 2 are arranged on support shafts 3 and 4, on the drive pins 3a, 4a of which the helical gear meshing drive gears 5 and 6 are seated.
- the lower support shaft 4 with the knife drum 2 is mounted in fixed roller bearings 7 and 8 in the support frame 9 of the drum shears.
- the upper support shaft 3 is supported in roller bearings 10 and 11, which permit an axial displacement of its inner ring 10a, 11a with the rollers relative to the outer ring 10b, 11b arranged fixedly in the support frame 9.
- a pin shoulder 12 is placed, which is surrounded by an inner ring collar 14a of a cylinder sleeve 14 which is piston-like in a guide 15 arranged in the support frame 9 in the direction of the axis of rotation of the support shaft 3.
- the ring end faces of the collar 14a are bordered by two axial bearings 16 and 17 seated on the pin boss 12 and axially fixed by a nut 18 screwable onto a threaded end 12a of the pin boss 12.
- the cylinder sleeve 14 has on its ring face facing away from the inner ring 14a a flange cover 19 with a central threaded bore 19a into which a threaded spindle 20 engages, which can be set in rotation by a motor 40 via a worm gear 22.

Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Einstellung des Messerspaltes an Trommelscheren, deren fest auf einem Tragwellenpaar mit schrägverzahnten Antriebszahnrädern sitzende Messertrommeln Längsausnehmungen für die Aufnahme von Messerblöcken aufweisen, in denen diese mit Hilfe von an Spannkeilen angreifenden druckbeaufschlagbaren Befestigungselementen festklemmbar sind.The invention relates to a device for adjusting the knife gap on drum shears, the knife drums of which are seated firmly on a pair of support shafts with helical toothed drive gears and have longitudinal recesses for receiving knife blocks in which these can be clamped with the aid of fastening elements which can be pressurized and act on clamping wedges.
Bei Trommelscheren dieser Art wird die Einstellung des Messerspaltes bisher in der Weise durchgeführt, daß eines der schrägverzahnten Antriebszahnräder auf seinem Sitz auf dem Zapfen der Tragwelle mit Hilfe einer Stelleinrichtung axial verschoben wird und dabei, bedingt durch die radiale Komponente der Abstützkraft auf den Gegenzähnen des anderen schrägverzahnten Antriebszahnrades eine relative Drehversetzung der Messertrommel gegenüber der anderen Messertrommel bewirkt, mit der sich die Breite des Messerspaltes der Messerblöcke beider Trommeln einstellen läßt. Die Vorrichtung bringt den wesentlichen Nachteil mit sich, daß das Antriebszahnrad auf dem Wellenzapfen der Radwelle der Messertrommel drehfest aber axial verschiebbar angeordnet werden, und daß diese Verschiebbarkeit während des Schneidbetriebes der Scheren wieder aufgehoben, d.h. blockiert werden muß. Diese Notwendigkeit erforderte einen erheblichen technischen Aufwand, nämlich z.B. achsparallel in Nuten zwischen Tragwellenzapfen und Antriebszahnrad verschiebbare Stellkeile mit axialen Sicherungselementen sowie eine auf die Stirnseite des Zapfens aufgesetzte Verschiebeeinrichtung für die Keile.In drum shears of this type, the setting of the knife gap has so far been carried out in such a way that one of the helical drive gearwheels on its seat on the journal of the supporting shaft is axially displaced with the aid of an actuating device and, due to the radial component of the supporting force on the counter teeth of the other helical drive gear causes a relative rotational displacement of the knife drum relative to the other knife drum, with which the width of the knife gap of the knife blocks of both drums can be adjusted. The device has the main disadvantage that the drive gear on the shaft journal of the wheel shaft of the knife drum are arranged in a rotationally fixed but axially displaceable manner, and that this displaceability has to be canceled again during the cutting operation of the scissors, that is to say blocked. This necessity required considerable technical effort, namely Eg axially parallel in the grooves between the support shaft journal and drive gear adjustable wedges with axial locking elements and a sliding device placed on the end face of the pin for the wedges.
Für rotierende Scheren mit schrauben- oder spiralförmig auf dem Umfang der Messertrommel verlaufenden Messern wurde bereits vorgeschlagen, die hier sehr schwierige Ausrichtung der Scherenmesser durch Verschwenken der Lager einer der beiden Tragwellen der Messertrommeln zu bewirken und dabei zusätzlich zur Einstellung des genauen Spiels der so eingestellten Messer die eine der beiden Tragwellen mit der Messertrommel und dem schrägverzahnten Antriebszahnrad axial zu verschieben und auf diese Weise eine Drehversetzung der einen Messertrommel gegenüber der anderen herbeizuführen. Für die Einstellung des Messerspaltes bei den gattungsgemäßen Trommelscheren eignet sich eine solche Vorrichtung zur axialen Verschiebung einer Tragwelle deshalb nicht, weil die Schneidkanten der Messerblöcke durchweg konvex nach außen bogenförmig verlaufen und deshalb bei axialer Verschiebung einer der Messertrommeln zusammen mit dem auf der Trommel sitzenden Messerblock die Schneidsymetrie zwischen dem Messerblock der einen und der anderen Messertrommel gestört und damit ein Schneiden unmöglich gemacht würde (DE-AS 2037270).For rotating shears with helical or spiral knives running on the circumference of the knife drum, it has already been proposed to bring about the very difficult alignment of the shear knives by pivoting the bearings of one of the two support shafts of the knife drums and in addition to adjusting the exact play of the knives set in this way to axially shift one of the two support shafts with the knife drum and the helical toothed drive gear and in this way bring about a rotational displacement of one knife drum relative to the other. Such a device for axially displacing a support shaft is not suitable for adjusting the knife gap in the generic drum shears because the cutting edges of the knife blocks are all convex to the outside in an arcuate manner and therefore when one of the knife drums is axially displaced together with the knife block sitting on the drum Cutting symmetry between the knife block of one and the other knife drum is disturbed, making cutting impossible (DE-AS 2037270).
Ausgehend von einer bekannten Vorrichtung zur Befestigung der Messerblöcke in Längsausnehmungen des Umfangs der Messertrommeln mit Hilfe von an Spannkeilen angreifenden druckbeaufschlagbaren Befestigungselementen die es z.B. erlauben, die Druckbeaufschlagung der Befestigungselemente durch hydraulischen Gegendruck aufzuheben und damit die Messerblöcke in den Längsausnehmungen verschiebbar zu machen hat sich die Erfindung die Aufgabe gestellt, die Vorrichtung zur Einstellung des Messerspaltes an den gattungsgemäßen Trommelscheren so zu verbessern, daß die Nachteile der aufwendigen Vorrichtungen zur Verschiebung eines Antriebszahnrades auf der Tragwelle und dessen Blockierung vermieden werden und die axiale Stellung beider Messerblöcke zue nander während des Einstellvorgangs des Messerspaltes unverändert bleibt.Starting from a known device for fastening the knife blocks in longitudinal recesses of the circumference of the knife drums with the aid of pressurizable fasteners which act on clamping wedges and which, for example, allow the pressurization of the fasteners to be released by hydraulic counterpressure and thus make the knife blocks displaceable in the longitudinal recesses the task, the device to improve the knife gap on the generic drum shears so that the disadvantages of the complex devices for moving a drive gear on the support shaft and its blocking are avoided and the axial position of both knife blocks zue nander remains unchanged during the setting process of the knife gap.
Diese Aufgabe wird durch im Tragrahmen der Trommelschere angeordnete, die Messerbalken während einer Axialverschiebung an einer der Tragwellen mit Messertrommel und Antriebszahnrad gegenüber der anderen in ihrer Lage in den Längsausnehmungen der Messertrommel festlegende Halteanschläge , gelöst. Diese Halteanschläge können, wie die Erfindung weiter vorsieht, in den Bereich der Stirnflächen der Messerblöcke, diese beaufschlagende ein- und herausfahrbare Anschlagstücke aufweisen.This object is achieved by holding stops arranged in the supporting frame of the drum shears and fixing the cutter bars during an axial displacement on one of the supporting shafts with cutter drum and drive gear wheel relative to the other in their position in the longitudinal recesses of the cutter drum. As the invention further provides, these holding stops can have stop pieces which can be moved in and out in the area of the end faces of the knife blocks.
Die Halteanschläge halten den Messerbalken der sich in der Längsausnehmung der durch Axialverschiebung zu verstellenden Messertrommel befindet während des Verschiebevorgangs in seiner ursprünglichen Lage zu dem Messerbalken der anderen, nicht verschobenen Messertrommel fest, so daß die Lage der Schneiden beider Messer quer zur radialen unverändert bleibt. Für den Verstellvorgang ist es lediglich notwendig, die Druckbeaufschlagung der die Spannkeile angreifenden Befestigungselemente aufzuheben, damit der Messerbalken in der Längsausnehmung relativ zur Messertrommel verschiebbar ist, d.h. daß die Messertrommel bei festgehaltenem Messerbalken axial verschoben werden kann. Nach Beendigung des Einstellvorgangs werden die Befestigungselemente der Spannkeile erneut der Druckbeaufschlagung ausgesetzt und die Halteanschläge aus dem Bereich der Messerbalken herausgefahren.The holding stops hold the knife bar in the longitudinal recess of the knife drum to be adjusted by axial displacement during the displacement process in its original position relative to the knife bar of the other, not displaced knife drum, so that the position of the cutting edges of both knives remains unchanged transversely to the radial one. For the adjustment process, it is only necessary to release the pressurization of the fastening elements engaging the clamping wedges, so that the knife bar can be displaced in the longitudinal recess relative to the knife drum, i.e. that the knife drum can be moved axially while holding the knife bar. After the adjustment process has been completed, the fastening elements of the clamping wedges are again subjected to pressure and the holding stops are moved out of the area of the cutter bars.

Wie aus Fig. 1 zu ersehen, sind die beiden Messertrommeln 1 und 2 auf Tragwellen 3 und 4 angeordnet, auf deren Antriebszapfen 3a, 4a die schrägverzahnten, miteinander kämmenden Antriebszahnräder 5 und 6 sitzen. Die untere Tragwelle 4 mit der Messertrommel 2 lagert in festen Rollenlagern 7 und 8 im Tragrahmen 9 der Trommelschere. Die obere Tragwelle 3 lagert in Rollenlagern 10 und 11, die eine Axialverschiebung ihres Innenrings 10a, 11a mit den Rollen gegenüber dem fest im Tragrahmen 9 angeordneten Außenring 10b, 11b zulassen. Auf den, dem Antriebszapfen 3a abgewandten Zapfen 3b der Tragwelle 3 ist stirnseitig ein Zapfenansatz 12 aufgesetzt, der von einem Innenringbund 14a einer Zylinderhülse 14 umfaßt wird, die kolbenartig in einer im Tragrahmen 9 angeordneten Führung 15 in Richtung der Drehachse der Tragwelle 3 verschiebbar ist. Die Ringstirnflächen des Ringbundes 14a werden von zwei auf dem Zapfenansatz 12 sitzenden Axiallagern 16 und 17 eingefaßt und durch eine auf ein Gewindeende 12a des Zapfenansatzes 12 aufschraubbare Mutter 18 axial festgelegt. Die Zylinderhülse 14 trägt auf ihrer dem Innenring 14a abgewandten Ringstirn einen Flanschdeckel 19 mit einer zentralen Gewindebohrung 19a, in die eine Gewindespindel 20 eingreift, die über ein Schneckengetriebe 22 von einem Motor 40 in Drehung versetzt werden kann. Auf dem freien Ende der Spindel 20 sitzt ein Stellarm 21 mit Rastnocken 23 die in eine Lochscheibe 24 ein- und ausfahrbar sind. Diese Lochscheibe 24 ist auf nicht dargestellte Weise mit einer Anzeigenskala versehen, die dem Stellarm 21 zugeordnet ist.As can be seen from FIG. 1, the two

Die einander zugewandten zur Senkrechten leicht geneigten Halteflächen 27a dieser Anschlagstücke beaufschlagen die Stirnflächen 29a der Messerbalken 29 in den Längsausnehmungen 1a der Messertrommel 1. Diese Messerbalken 29 sind, wie sich ais Fig. 2 ergibt, mittels eines Spannkeils 30 der über eine Zugstange 32 unter der Wirkung eines Federpaketes 33 steht, in der Längsausnehmung 1a festklemmbar. Die Zugstange 32 trägt an ihrem dem Spannkeil 30 abgewandten Ende einen in einem Zylinderstück 35 geführten Kolben 34 der über eine Zuleitung 36 auf nicht dargestellte Weise mit einem Druckmittel beaufschlagbar ist. Bei Beaufschlagung des Kolbens 34 mit dem Druckmittel wird der Spannkeil 30 entgegen der Wirkung des Federpaketes 33 außer Spannlage gebracht und der Messerbalken 29 kann in der Längsausnehmung 1a gleiten. Wenn die Halteflächen 27a der Anschlagstücke 27 die beiden Stirnflächen 29a der Messerbalken 29 in der in Fig. 1 dargestellten Weise beaufschlagen bleibt der Messerbalken 29 in der gezeichneten Stellung während die Messertrommel 1 bei Betätigung des Motors 40 durch die Spindel 20 über die Zylinderhülse 14 und deren Innenringbund 14a axial in Richtung der eingezeichneten Pfeile V in der einen oder anderen Richtung verschoben wird. Den Verschiebeweg zeigt der Stellarm 21 auf der (nicht dargestellten) Skala an, und die Vorrichtung kann anschließend, nachdem der Messerbalken 29 mit Hilfe des Spannkeils 30 und des Federpaketes 33 in der Längsausnehmung 1a wieder festgeklemmt wurde durch Einfahren des Rastnockens 23 in eine Lochung der Lochscheibe 24 arretiert werden.
