Abstract

The device has a machine bed with one stationary and one movable machine unit. Roller rails (20) of both units are height-adjustable via a common drive (25). The same drive is for simultaneous height-adjustment of the hold-down brushes (32). The drive is coupled to a shaft (26). This extends in the process direction, and connects the two machine units (14,15). For each unit, the shaft has a threaded spindle (24) with a height- adjustable sleeve (30), which is indirectly fastened to the roller rail. The drive momentum is transmitted from the shaft via a herringbone gear drive (27) and two chain pulleys (28,29), to the spindle.

Description

Die Erfindung betrifft eine Vorrichtung zum Entgraten der Stirnflächen von stabförmigen Werkstücken, wie Profilrohre od. dgl., mit einem Maschinenbett, auf dem eine feste und eine verfahrbare Maschineneinheit angeordnet sind, die jeweils eine quer zur Verfahrrichtung angeordnete Walzenbürste tragen und eine aus einer Kette und daran angeordneten Mitnehmern bestehende, quer zur Verfahrrichtung an jeder Maschineneinheit befestigte Transportvorrichtung aufweisen, wobei die rotierenden Walzenbürsten die auf höhenverstellbaren Abrolleisten zwischen den Maschineneinheiten lagernden Rohrprofile beim Vorbeitransport stirnseitig entgraten, während über den Abrolleisten angeordnete Niederhalterbürsten die Rohrprofile belasten.The invention relates to a device for deburring the end faces of rod-shaped workpieces, such as profile pipes or the like., With a machine bed on which a fixed and a movable machine unit are arranged, each of which carries a roller brush arranged transversely to the direction of travel and one made of a chain and attached carriers have existing, transversely to the direction of travel attached to each machine unit, the rotating roller brushes deburring the pipe profiles stored on height-adjustable roller bars between the machine units at the end as they are transported past, while hold-down brushes arranged above the roller bars load the tube profiles.

Eine derartige Vorrichtung ist indirekt bereits in der DE-OS 21 52 229 beschrieben. In dieser Druckschrift wird ausgehend von einer Vorrichtung, in der die Achse jeder Walzenbürste fest am Maschinenkörper angebracht und die Auflageschienen jeweils in ihrer Höhe verstellbar sind, eine erfindungsgemäße Vorrichtung beschrieben, bei der die sogenannten Auflageschienen fest am Maschinenkörper angeordnet sind, während die Walzenbürsten horizontal verstellbar sind. In dieser Schrift wird behauptet, daß es in der Praxis wesentlich günstiger ist, anstatt der Auflageschienen jede einzelne Walzenbürste horizontal verstellbar in der Vorrichtung anzuordnen.Such a device has already been described indirectly in DE-OS 21 52 229. In this document, starting from a device in which the axis of each roller brush is firmly attached to the machine body and the support rails are each adjustable in height, a device according to the invention is described in which the so-called support rails are fixed to the machine body, while the roller brushes are horizontally adjustable are. This document claims that in practice it is much cheaper to arrange each individual roller brush horizontally adjustable in the device instead of the support rails.

Eine vertikale Verstellung der Walzenbürsten ist einerseits notwendig, da in Abhängigkeit von der vertikalen Position der Walzenbürste zu einem Profil eine Außenentgratung, eine Innen- und Außenentgratung bzw. eine Innenentgratung eines Profils möglich ist. Darüber hinaus ist die vertikale Verstellung auch als Anpassung an unterschiedliche Profildurchmesser notwendig.Vertical adjustment of the roller brushes is necessary on the one hand, since depending on the vertical position of the roller brush relative to a profile, external deburring, internal and external deburring or internal deburring of a profile is possible. In addition, vertical adjustment is also necessary to adapt to different profile diameters.

Des weiteren ist aus dem Stand der Technik eine an sich vorteilhafte Maschine der Anmelderin im Prospekt RSA Entgrat-Automaten RASAPLAN "Die rationelle Systemtechnik für Rohre, Profile und Vollmaterialien." beschrieben, bei der - wie in der zuvor genannten DE-OS 21 52 259 vorgeschlagen - eine vertikale Verstellung der Walzenbürsten möglich ist. Bei diesem grundsätzlich vorteilhaften Stand der Technik hat es sich jedoch als Nachteil herausgestellt, daß die Walzenbürsten auf der Fest- und der Losseite neben der sowieso notwendigen horizontalen Verstellung auch vertikal einzeln verstellt werden müssen. Dadurch ergeben sich auch bei erfahrenen Maschinenführern derartiger Automaten naturgemäß Abweichungen der Einstellung der beiden Walzenbürsten, welche sich auf den Erfolg der Entgratung an den beiden Stirnseiten eines Werkstückes unterschiedlich auswirkt.Furthermore, from the state of the art, an advantageous machine of the applicant in the brochure RSA deburring machines RASAPLAN is "The rational system technology for pipes, profiles and solid materials." described, in which - as proposed in the aforementioned DE-OS 21 52 259 - a vertical adjustment of the roller brushes is possible. In this fundamentally advantageous state of the art, however, it has turned out to be a disadvantage that the roller brushes on the fixed and the loose side must also be individually adjusted vertically in addition to the horizontal adjustment which is necessary anyway. Even experienced machine operators of such machines naturally have deviations in the setting of the two roller brushes, which have different effects on the success of the deburring on the two end faces of a workpiece.

Darüber hinaus ist die Einzelverstellung der Walzenbürsten auch nicht handhabungsfreundlich, da zumindestens die Walzenbürste auf der verfahrbaren Losseite für den Maschinenführer aufgrund der Zufuhreinrichtungen für die Profile nur sehr schwer erreichbar ist und er des weiteren in diesem Bereich auch nur ungünstige Arbeitsbedingungen vorfindet. Die getrennte vertikale Verstellung erschwert auch die Möglichkeit der automatischen Werkstückhöheneinstellung und erfordert einen sehr hohen technischen AufwandIn addition, the individual adjustment of the roller brushes is also not easy to handle, since at least the roller brush on the movable loose side is very difficult for the machine operator to reach due to the feeding devices for the profiles he also finds only unfavorable working conditions in this area. The separate vertical adjustment also complicates the possibility of automatic workpiece height adjustment and requires a very high level of technical effort

Letztlich ist es bei diesem Stand der Technik auch nachteilig anzusehen, daß aufgrund der vertikalen Verstellung jeder einzelnen Walzenbürste die Lagerung der Walzenbürste sehr massiv ausgestaltet sein muß, damit sie in der Lage ist, die von der mit hoher Umdrehungsgeschwindigkeit rotierenden Walzenbürsten ausgehenden Schwingungen aufzunehmen. Auch ist eine Höhenverstellung der Walzenbürsten unvorteilhaft, da die Bürstenlagerungen und die entsprechenden Mechanismen der Höhenverstellung im Bereich stärkster Verschmutzung durch den Entgratstaub liegen und so sehr häufig gereinigt und gewartet werden müssen.Ultimately, it is also a disadvantage of this prior art that, due to the vertical adjustment of each individual roller brush, the roller brush bearing must be designed very solidly so that it is able to absorb the vibrations emanating from the roller brushes rotating at high rotational speed. A height adjustment of the roller brushes is also disadvantageous, since the brush bearings and the corresponding mechanisms of the height adjustment are in the area of heaviest contamination by the deburring dust and therefore have to be cleaned and serviced very often.

Ausgehend von dem zuerst beschriebenen Stand der Technik besteht daher die Aufgabe der Erfindung darin, eine einfach herzustellende und zu bedienende Vorrichtung zu schaffen, bei der unabhängig von der Qualifikation des Bedieners automatisch eine gleichmäßige Entgratung beider Stirnseiten eines Rohrprofils sichergestellt ist.Based on the first described prior art, the object of the invention is to provide a device that is easy to manufacture and operate and that automatically ensures that both end faces of a tubular profile are automatically deburred regardless of the operator's qualifications.

Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruch 1, insbesondere den Merkmalen des Kennzeichenteils, wonach zumindestens die Abrolleisten der festen und der verfahrbaren Maschineneinheit über einen gemeinsamen Antrieb höhenverstellbar sind.The solution to this problem results from the features of claim 1, in particular the features of the identification part, according to which at least the scroll bars of the fixed and the movable machine unit are height-adjustable via a common drive.

Die erfindungsgemäße Vorrichtung hat den wesentlichen Vorteil, daß mit Hilfe der zwangsweise gleichzeitig stattfindenden Verstellung der Abrolleisten immer eine parallele Verstellung gewährleistet ist, so daß die durch die Abrolleisten definierte sich immer in der Waage befindet. Dies wirkt sich nicht nur vorteilhaft auf den Entgraterfolg und die Werkstückhöhenverstellung aus, sondern die erfindungsgemäße Art der Verstellung der Entgratmaschine ist, da sie insgesamt von der Festseite aus folgen kann, wesentlich handhabungs- und bedienungsfreundlicher und kann in vorteilhafter Weise automatisiert werden.The device according to the invention has the essential advantage that a parallel adjustment is always ensured with the help of the compulsory adjustment of the unrolling bars, so that the one defined by the unrolling bars is always in the balance. This not only has an advantageous effect on the deburring success and the workpiece height adjustment, but the type of adjustment of the deburring machine according to the invention is much easier to handle and use, since it can follow from the fixed side, and can be automated in an advantageous manner.

Darüber hinaus hat diese Art der gleichzeitigen Anpassung von Festseite und Losseite den maschinentechnischen Vorteil, daß die Lagerung der Walzenbürsten in den beiden Maschineneinheiten deutlich einfacher ausgestaltet werden kann, da die Lagerabstützung jetzt an beiden Seiten der einzelnen Walzenbürsten fest mit dem umgebenden Rahmen verbunden werden kann.In addition, this type of simultaneous adjustment of the fixed side and the loose side has the mechanical advantage that the bearing arrangement of the roller brushes in the two machine units can be made much easier, since the bearing support can now be firmly connected to the surrounding frame on both sides of the individual roller brushes.

Bei einer vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung sind darüber hinaus auch gleichzeitig die Niederhalterbürsten über den gemeinsamen Antrieb höhenverstellbar. Diese erfindungsgemäße Vorrichtung hat den Vorteil, daß dadurch weitere manuelle Handgriffe auf der Fest- und Losseite entfallen können, die Automatisierung der Maschine möglich wird und die gleichbleibende Qualität der Entgratung beider Werkstückstirnseiten sichergestellt ist.In an advantageous embodiment of the device according to the invention, the hold-down brushes are also simultaneously height-adjustable via the common drive. This device according to the invention has the advantage that further manual manipulations on the fixed and loose sides can thereby be omitted, the automation of the machine is possible and the constant quality of the deburring of both workpiece end faces is ensured.

Bei einer weiteren erfindungsgemäßen Ausführungsform ist der Antrieb mit einer in Verfahrrichtung verlaufenden, beide Maschineneinheiten verbindenen Welle verbunden, welche je Maschineneinheit auf mindestens eine Gewindespindel einwirkt, deren höhenverstellbare Hülse zumindest mittelbar an der Abrolleiste befestigt ist.In a further embodiment according to the invention, the drive is connected to a shaft which runs in the direction of travel and connects both machine units and which acts on at least one threaded spindle per machine unit, the height-adjustable sleeve of which is at least indirectly attached to the unwinding bar.

Dabei handelt es sich um einen einfach aufgebauten und darüber sehr zuverlässig funktionierenden, gleichzeitigen Antrieb zur Höhenverstellung der beidseitigen Abrolleisten, bei der das Antriebsmoment in jeder Maschineneinheit von der Welle über ein Winkelzahnradgetriebe auf ein Kettenrad übertragen wird, welches antriebsmäßig über je ein weiteres Kettenrad mit wenigstens zwei der Höhenverstellung der Abrolleiste dienenden, beabstandeten Gewindespindeln verbunden ist.This is a simply constructed and above all very reliably functioning, simultaneous drive for height adjustment of the two-sided unrolling bars, in which the drive torque in each machine unit is transmitted from the shaft via an angular gear drive to a sprocket, which is driven by at least one additional sprocket two spaced threaded spindles serving to adjust the height of the rolling bar are connected.

Letztlich umfaßt die Erfindung auch einen Antrieb mit einer in Verfahrrichtung verlaufenden, beide Maschineneinheiten verbindenen Welle, welche je Maschineneinheit auf mindestens eine in einem Gehäuse drehbar gelagerte Antriebsmutter einwirkt, in der eine höhenverstellbare Trapezspindel angeordnet ist, welche die Abrolleiste trägt.Ultimately, the invention also includes a drive with a shaft extending in the direction of travel, connecting the two machine units, which acts on each machine unit on at least one drive nut rotatably mounted in a housing, in which a height-adjustable trapezoidal spindle is arranged, which carries the rolling bar.

Bei dieser Antriebsvorrichtung wird auf vorteilhafte Weise das Antriebsmoment in jeder Maschineneinheit von der Vielkeilwelle über ein Winkelzahnradgetriebe auf die Antriebsmutter und über eine daran angeordnete Kettenradscheibe auf mindestens eine weitere, beabstandete Antriebsmutter übertragen.In this drive device, the drive torque in each machine unit is advantageously transmitted from the splined shaft to the drive nut via an angular gear drive and to at least one further, spaced drive nut via a sprocket disk arranged thereon.

Zum Zwecke der einfachen Übertragung des Drehmoments im Bereich der verfahrbaren Maschineneinheit von der Welle auf die Höhenverstellung ist die Welle dort als Vielkeilwelle ausgebildet.For the purpose of simply transferring the torque in the area of the movable machine unit from the shaft to the height adjustment, the shaft is designed there as a splined shaft.

In den Zeichnungen ist eine Vorrichtung zum Entgraten der Stirnflächen von stabförmigen Werkstücken, wie Profilrohre od. dgl., insgesamt mit der Bezugsziffer 10 bezeichnet.In the drawings, a device for deburring the end faces of rod-shaped workpieces, such as profiled tubes or the like, is generally designated by the reference number 10.

Die Vorrichtung 10 weist ein Maschinenbett 11 auf, welches aus zwei Sockeln 12 und zwei Verfahrschienen 13 besteht. Auf dem Maschinenbett 11 ist eine feste Maschineneinheit 14 und eine verfahrbare Maschineneinheit 15 angeordnet. Beide Maschineneinheiten 14 und 15 weisen jeweils quer zu einer Verfahrrichtung x angeordnete Walzenbürsten 16 auf. Im Bereich der Walzenbürsten 16 ist jede Maschineneinheit 14 oder 15 jeweils mit einer Transporteinrichtung 17 versehen, welche gemeinsam angetrieben werden und jeweils aus einer Kette 18 mit daran angeordneten Mitnehmern 19 bestehen. Oberhalb der Transportvorrichtung 17 ist eine an der festen Maschineneinheit 14 angeordnete Niederhalterbürste N zu erkennen.The device 10 has a machine bed 11, which consists of two bases 12 and two travel rails 13. A fixed machine unit 14 and a movable machine unit 15 are arranged on the machine bed 11. Both machine units 14 and 15 each have roller brushes 16 arranged transversely to a direction of travel x. In the area of the roller brushes 16, each machine unit 14 or 15 is each provided with a transport device 17, which are driven together and each consist of a chain 18 with drivers 19 arranged thereon. A hold-down brush N arranged on the fixed machine unit 14 can be seen above the transport device 17.

Wie in Fig. 2 dargestellt, ist jeweils zwischen einer Walzenbürste 16 und der Transportvorrichtung 17 eine sogenannte Abrolleiste 20 angeordnet. Über eine nicht dargestellte Zuführeinrichtung werden Rohrprofile 21 der Transportvorrichtung 17 zugeführt, von den Mitnehmern 19 erfaßt und bei gleichzeitiger Abrollbewegung auf den Abrolleisten 20 entlang der Walzenbürsten 16 bewegt. Dabei werden Stirnflächen 22 von den aus Spezialdrähten bestehenden Walzenbürsten 16 entgratet.As shown in FIG. 2, a so-called rolling bar 20 is arranged between a roller brush 16 and the transport device 17. Via a feed device, not shown, tube profiles 21 are fed to the transport device 17, gripped by the drivers 19 and moved along the roller brushes 16 with a simultaneous rolling movement on the rolling bars 20. End faces 22 are deburred by the roller brushes 16 made of special wires.

In der Prinzipskizze gemäß Fig. 2 ist zu erkennen, daß sich die Walzenbürsten 16 gegensinnig bewegen, während die Rohrprofile 21 in y-Richtung auf den Abrolleisten 20 an den Walzenbürsten 16 vorbeigerollt werden, wobei auf in Fig. 2 nicht dargestellte Weise Niederhalterbürsten auf die Rohrprofile 21 einwirken.2 it can be seen that the roller brushes 16 move in opposite directions, while the tubular profiles 21 are rolled past the roller brushes 16 in the y-direction on the rolling bars 20, with hold-down brushes on the roller brushes in a manner not shown in FIG. 2 Act tube profiles 21.

In Abhängigkeit von der Länge der Rohrprofile 21 ist es nun möglich - wie in Fig. 1 erkennbar - die verfahrbare Maschineneinheit 15 in einem kleineren oder größeren Abstand zur festen Maschineneinheit 14 und der darin angeordneten Walzenbürste 16 zu verfahren. Damit kann die Vorrichtung 10 an die Länge der Rohrprofile 21 angepaßt werden. Darüber hinaus ist eine Feineinstellung des Abstandes der beiden Walzenbürsten 16 voneinander durch eine horizontale Verstellung der Walzenbürsten 16 in jeder einzelnen Maschineneinheit 14 oder 15 möglich, wodurch die Stärke der Entgratung gesteuert werden kann.Depending on the length of the tubular profiles 21, it is now possible - as can be seen in FIG. 1 - to move the movable machine unit 15 at a smaller or greater distance from the fixed machine unit 14 and the roller brush 16 arranged therein. The device 10 can thus be adapted to the length of the tubular profiles 21. In addition, a fine adjustment of the distance of the two roller brushes 16 from one another is possible by a horizontal adjustment of the roller brushes 16 in each individual machine unit 14 or 15, whereby the strength of the deburring can be controlled.

Letztlich ist es auch möglich - wie im einzelnen in den Fig. 3 bis 5 dargestellt - die Abrolleisten 20 in bezug zu den Walzenbürsten 16 vertikal zu verstellen. Dies hat grundsätzlich den Vorteil, daß in Abhängigkeit davon, ob eine Außenentgratung, einen Innen- und Außenentgratung bzw. eine Innenentgratung eines Profils durchgeführt werden soll, die Lage des auf den Abrolleisten 20 sich bewegenden Rohrprofils 21 gegenüber den Walzenbürsten 16 veränderbar ist.Ultimately, it is also possible - as shown in detail in FIGS. 3 to 5 - to vertically adjust the rolling bars 20 with respect to the roller brushes 16. Basically, this has the advantage that, depending on whether an external deburring, an internal and external deburring or an internal deburring of a profile is to be carried out, the position of the tubular profile 21 moving on the rolling bars 20 can be changed relative to the roller brushes 16.

In der Fig. 3 ist eine Höhenverstellung 23 einer Abrolleiste 20 mit Hilfe einer Gewindespindel 24 dargestellt. Ausgehend von einem auf der Festseite (Maschineneinheit 14) angeordneten Antriebsmotor 25 wird eine beide Maschineneinheiten 14 und 15 verbindende Welle 26 angetrieben, welche im Bereich der Maschineneinheit 14 als zylinderische Welle 26 a und im Bereich der Maschineneinheit 15 als Vielkeilwelle 26 b ausgebildet ist. Das Antriebsmoment wird von der Welle 26 im Bereich jeder Maschineneinheit 14 und 15 über ein Winkelzahnradgetriebe 27 auf ein Kettenrad 28 übertragen. Das Winkelzahnradgetriebe 27 wird durch zwei Kegelräder K1 und K2 gebildet. Im Bereich der Maschineneinheit 14 ist das Kegelrad K1 mittels einer Spannbüchse S auf der zylinderischen Welle 26 a angeordnet, während das Kegelrad K2 auf einer senkrecht zur Welle 26 angeordneten Welle W gelagert ist, welche auch das Kettenrad 28 trägt. Vom Kettenrad 28 wird über ein weiteres Kettenrad 29, welches auf der Gewindespindel 24 angeordnet ist, das Antriebsmoment auf eine Hülse 30 der Gewindespindel 24 übertragen, die über einen Tragarm 31 mit einer Abrolleiste 20 verbunden ist.3 shows a height adjustment 23 of a rolling bar 20 with the aid of a threaded spindle 24. Starting from a drive motor 25 arranged on the fixed side (machine unit 14), a shaft 26 connecting both machine units 14 and 15 is driven, which is formed in the area of the machine unit 14 as a cylindrical shaft 26 a and in the area of the machine unit 15 as a splined shaft 26 b. The drive torque is from the shaft 26 in the area of each machine unit 14 and 15 via an angular gear 27 to a sprocket 28. The bevel gear 27 is formed by two bevel gears K 1 and K 2 . In the area of the machine unit 14, the bevel gear K 1 is arranged on the cylindrical shaft 26 a by means of a clamping sleeve S, while the bevel gear K 2 is mounted on a shaft W arranged perpendicular to the shaft 26, which also carries the chain wheel 28. The drive torque is transmitted from the sprocket 28 via a further sprocket 29, which is arranged on the threaded spindle 24, to a sleeve 30 of the threaded spindle 24, which is connected to a rolling bar 20 via a support arm 31.

In der perspektivischen Zeichnung gemäß Fig. 4 ist zu erkennen, daß jede Abrolleiste 20 über zwei beabstandete, mit jeweils einer Gewindespindel 24 versehenen Höhenverstellungen 23 erfolgt, welche mittels einer gemeinsamen Antriebskette k über das Kettenrad 28 angetrieben werden.In the perspective drawing according to FIG. 4 it can be seen that each rolling bar 20 takes place via two spaced height adjustments 23, each provided with a threaded spindle 24, which are driven by means of a common drive chain k via the chain wheel 28.

Ebenso wie die den Antrieb 25 aufnehmende Maschineneinheit 14 weist die verfahrbare Maschineneinheit 15 zwei oben beschriebene Vorrichtungen 23 auf. Im Unterschied zur Maschineneinheit 14 ist das Kegelrad K1 nicht mit einer Spannbüchse S auf der Vielkeilwelle 26 b sondern gehäuseseitig gelagert, so daß eine volle Verfahrbarkeit der Maschineneinheit 15 in Verfahrrichtung x gegeben ist.Just like the machine unit 14 receiving the drive 25, the movable machine unit 15 has two devices 23 described above. In contrast to the machine unit 14, the bevel gear K 1 is not supported with a clamping bush S on the splined shaft 26 b, but on the housing side, so that the machine unit 15 can be fully moved in the direction of travel x.

In der Darstellung nach Fig. 3 ist nur auf der Festseite (Maschineneinheit 14) beispielhaft die Transportvorrichtung 17 mit ihren dazugehörigen Teilen (s. Fig. 2), die Abrolleiste 20 sowie eine in einem bestimmten Abstand oberhalb der Abrolleiste 20 angeordnete Niederhalterbürste 32 zu sehen, durch die ein kontrolliertes Abrollen der Rohrprofile 21 auf den Abrolleisten 20 ermöglicht wird.3, the transport device is only an example on the fixed side (machine unit 14) 17 with its associated parts (see FIG. 2), the unrolling bar 20 and a hold-down brush 32 arranged at a certain distance above the unrolling bar 20, by means of which a controlled unrolling of the tubular profiles 21 on the unrolling bars 20 is made possible.

Es ist zu erkennen, daß aufgrund der zwangsweise gleichzeitigen Verstellung der Gewindespindeln 24 in beiden Maschineneinheiten 14 und 15 eine Höhenverstellung der eine E definierenden Abrolleisten 20 erfolgen kann. In der Fig. 3 ist einerseits die höchste Stellung der Abrolleisten 20 strichpunktiert dargestellt und andererseits durch einen Doppelpfeil h der maximale Hub der Abrolleisten 20 zu erkennen.It can be seen that, due to the forced simultaneous adjustment of the threaded spindles 24 in both machine units 14 and 15, a height adjustment of the unrolling bars 20 defining an E can take place. In Fig. 3, the highest position of the scroll bars 20 is shown in dash-dotted lines on the one hand and on the other hand, the maximum stroke of the scroll bars 20 can be recognized by a double arrow h.

Die Fig. 5 stellt eine weitere Höhenverstellung 33 dar, bei der wiederum ausgehend von einem Antriebsmotor 25 und einer Welle 26 mit einem zylindrischen Wellenabschnitt 26 a und einer als Vielkeilwelle ausgebildeten Wellenabschnitt 26 b ein Drehmoment auf das Winkelzahnradgetriebe 27 übertragen wird. Im Unterschied zu dem vorherigen Ausführungsbeispiel ist das Winkelzahnradgetriebe 27 unmittelbar mit einer Antriebsmutter 34 verbunden, welche über Kugellager 35 in einem Lagergehäuse 36 drehbar angeordnet ist. Innerhalb der Antriebsmutter 34 ist eine Trapezspindel 37 ebenfalls drehbar gelagert, welche an ihrem oberen, aus der Antriebsmutter 34 herausschauenden Ende 38 Befestigungselemente 39 für die Abrolleiste 20 trägt. Zum gleichzeitigen Antrieb einer weiteren Höhenverstellung 33 je Maschineneinheit 14 oder 15 ist die Antriebsmutter 34 über eine horizontal gelagerte Kettenradscheibe 40 mit einer weiteren nicht dargestellten Höhenverstellung 33 verbunden.5 shows a further height adjustment 33, in which, starting from a drive motor 25 and a shaft 26 with a cylindrical shaft section 26 a and a shaft section 26 b designed as a splined shaft, a torque is transmitted to the angular gear transmission 27. In contrast to the previous exemplary embodiment, the bevel gear mechanism 27 is directly connected to a drive nut 34 which is rotatably arranged in a bearing housing 36 via ball bearings 35. Within the drive nut 34, a trapezoidal spindle 37 is also rotatably mounted, which carries 38 fastening elements 39 for the rolling bar 20 at its upper end 38 which protrudes out of the drive nut 34. For the simultaneous drive of a further height adjustment 33 per machine unit 14 or 15, the drive nut 34 is horizontal mounted sprocket 40 connected to a further height adjustment 33, not shown.

Durch diese Art der zwangsweisen Höhenverstellung der beiden Abrolleisten 20 ist in jeder Stellung sichergestellt, daß die durch die Abrolleisten 20 gebildete E sich immer in der Waage befindet.This type of forced height adjustment of the two rolling bars 20 ensures in every position that the E formed by the rolling bars 20 is always in the balance.

Ebenso wie bei der in Fig. 3 dargestellten Ausführungsform bestehen gewisse Unterschiede zwischen der Ausgestaltung der Höhenverstellung gemäß Maschineneinheit 14 (Festseite) und Maschineneinheit 15 (Losseite). Auf der Festseite ist nämlich das Kegelrad K1 wiederum über eine Spannbüchse S auf der zylindrischen Welle 26 a befestigt und kämmt mit dem Kegelrad K2, welches auf der im rechten Winkel zur Welle 26 verlaufenden Antriebsmutter 34 gelagert ist. Die Welle 26 ist darüber hinaus zwischen der Maschineneinheit 14 und der Maschineneinheit 15 in einem Führungsbauteil 41 drehbar gelagert.As in the embodiment shown in FIG. 3, there are certain differences between the design of the height adjustment according to machine unit 14 (fixed side) and machine unit 15 (loose side). On the fixed side, namely, the bevel gear K 1 is in turn fastened via a clamping bush S on the cylindrical shaft 26 a and meshes with the bevel gear K 2 , which is mounted on the drive nut 34 running at right angles to the shaft 26. The shaft 26 is also rotatably supported in a guide component 41 between the machine unit 14 and the machine unit 15.

Ein ähnliches Führungsbauteil 42, welches in der Konstruktion der Maschineneinheit 15 angeordnet ist, dient zur drehbaren Lagerung des in die Vielkeilwelle 26 b eingreifenden Kegelrads K1, welches wiederum mit einem auf der Antriebsmutter 34 angeordneten Kegelrad K2 kämmt. Durch diese Anordnung ist ähnlich wie bei der Ausführungsform gemäß Fig. 3 die volle Verfahrbarkeit der Maschineneinheit 15 gegeben.A similar guide component 42, which is arranged in the construction of the machine unit 15, serves for the rotatable mounting of the bevel gear K 1 engaging in the splined shaft 26 b, which in turn meshes with a bevel gear K 2 arranged on the drive nut 34. This arrangement, similar to the embodiment according to FIG. 3, gives the machine unit 15 full mobility.
