Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Führen der einzelnen Streifen eines in Längsstreifen geteilten Blechbandes mit einer in einem Gestell gehaltenen, quer zu den Längsstreifen verlaufenden, bandparallelen Stützrolle, die einen Führungskamm für die einzelnen Streifen bildende Scheiben trägt. Eine derartige Vorrichtung ist aus der FR-A-2 428 483 bekannt.The invention relates to a device for guiding the individual strips of a sheet metal strip divided into longitudinal strips with a support roller, which is held in a frame and runs transversely to the longitudinal strips and carries a guide comb for the disks forming the individual strips. Such a device is known from FR-A-2 428 483.

Um in Längsteilanlagen einen ausgerichteten Verlauf der Blechstreifen zu erzielen, müssen diese Streifen entsprechend geführt werden, zu welchem Zweck Stützrollen mit Scheiben vorgesehen sind, deren Abstand voneinander der jeweiligen Streifenbreite entspricht, so daß sich durch die auf der Stützrolle angeordneten Scheiben ein Führungskamm für die einzelnen Streifen ergibt. Derartige Vorrichtungen haben sich an sich gut bewährt, doch treten Schwierigkeiten auf, wenn es gilt, die einzelnen Streifen eines längsgeteilten Bandes zwischen die einzelnen Scheiben einzulegen. Beim Einziehen eines neuen Bandes in die Längsteilanlage müssen nämlich die einzelnen Streifen von Hand in die durch die Scheiben auf den Stützrollen gebildeten Führungskämme eingefädelt werden, was nicht nur arbeitsaufwendig, sondern auch gefährlich ist, insbesondere bei dickeren Blechen.In order to achieve an aligned course of the sheet metal strips in slitting lines, these strips must be guided accordingly, for which purpose support rollers with disks are provided whose spacing from one another corresponds to the respective strip width, so that the disks arranged on the support roller provide a guide comb for the individual Streak results. Such devices have proven themselves per se, but difficulties arise when it is a question of inserting the individual strips of a longitudinally divided band between the individual disks. When a new strip is pulled into the slitting line, the individual strips have to be threaded by hand into the guide combs formed by the disks on the support rollers, which is not only labor intensive, but also dangerous, especially with thicker sheets.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung zum Führen der einzelnen Streifen eines in Längsstreifen geteilten Blechbandes der eingangs geschilderten Art so zu verbessern, daß ein rasches und gefahrloses Einfädeln der einzelnen Bandstreifen ohne Handarbeit möglich wird.The invention is therefore based on the object of improving a device for guiding the individual strips of a sheet metal strip divided into longitudinal strips of the type described at the outset in such a way that the individual strip strips can be threaded quickly and safely without manual labor.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die Stützrolle in einem im Gestell mittels eines Antriebes quer zu den Längsstreifen und bandparallel hin- und herverschiebbaren Schlitten gelagert ist.The invention achieves the stated object in that the support roller is mounted in a carriage that can be pushed back and forth parallel to the longitudinal strips and parallel to the belt in the frame by means of a drive.

Die durch den verschiebbar gelagerten Schlitten und dessen Antrieb erreichte Verschiebemöglichkeit der Stützrolle quer zu den Längsstreifen gewährleistet ein automatisches Einfädeln der einzelnen Bandstreifen in den Führungskamm, weil durch die Hin- und Herbewegung der Stützrolle die einzelnen Bandstreifen auf alle Fälle zwischen die sie führenden Scheiben gelangen und von den Scheiben auf die Stützrolle abgleiten. Beim Einziehen eines neuen Bandes können daher die Streifenenden ohne besondere Vorkehrungen über die Stützrolle bewegt werden, wobei es unerheblich ist, ob die einzelnen Streifen bereits zwischen die Scheiben gleiten oder aus den Scheiben laufen. Durch die anschließende Querverschiebung des durch die Stützrolle und die Scheiben gebildeten Führungskammes und die damit verbundene Relativbewegung zwischen dem Führungskamm und den Längsstreifen gelangen die Bandstreifen sicher in die Führungsausnehmungen zwischen den Scheiben. Das Einfädeln der Bandstreifen in die Führungskämme kann daher ohne Unterbrechung des Einziehvorganges des Bandes erfolgen.The possibility of moving the support roller across the longitudinal strips achieved by the slidably mounted slide and its drive ensures automatic threading of the individual strip strips into the guide comb, because the individual strip strips definitely get between the leading discs and through the back and forth movement of the support roller slide off the discs onto the support roller. When pulling in a new band, the strip ends can therefore be moved over the support roller without special precautions, it being irrelevant whether the individual strips are already sliding between the disks or running out of the disks. As a result of the subsequent transverse displacement of the guide comb formed by the support roller and the disks and the relative movement associated therewith between the guide comb and the longitudinal strips, the band strips arrive safely in the guide recesses between the disks. The threading of the tape strips into the guide combs can therefore be carried out without interrupting the pulling-in process of the tape.

Es ist zwar bereits bekannt (US-A-3 848 788), das Treibwalzenpaar eines Treibgerüstes für Blechbänder in einem quer zur Förderrichtung des Blechbandes verschiebbar im Gerüstgestell gelagerten Schlitten vorzusehen, doch kann durch dieses bekannte Treibgerüst die Erfindung nicht nahegelegt werden, weil der das Treibwalzenpaar tragende Schlitten frei verschiebbar und durch Rückzugsfedern belastet ist, so daß bei einem Verlaufen des Blechbandes die Treibrollen durch die vom Band übertragenen Kräfte nach der einen oder anderen Seite ausweichen und das Band wieder zurückführen können. Die Treibrollen bilden daher keine Seitenführungen für das anzutreibende Band, das durch eine vorgeordnete Seitenführung ausgerichtet wird. Da das Band lediglich in den Spalt zwischen den beiden Treibrollen eingezogen werden muß, stellt sich bei dem bekannten Treibgerüst gar nicht die Aufgabe, die einzelnen Streifen eines in Längsstreifen geteilten Blechbandes in einen Führungskamm einzulegen. Erst durch das erfindungsgemäße Verschieben der den Führungskamm für die einzelnen Streifen bildenden Stützrolle quer zu den Bandlängsstreifen kann das selbsttätige Einfädeln der Streifen in den Führungskamm sichergestellt werden.Although it is already known (US-A-3 848 788) to provide the drive roller pair of a drive frame for sheet metal strips in a slide which is displaceable transversely to the conveying direction of the sheet metal strip, the invention cannot be suggested by this known drive frame, because of that Carriage roller pair carrying carriage is freely displaceable and loaded by return springs, so that when the sheet metal strip runs, the drive rollers dodge to one side or the other through the forces transmitted by the band and can return the band again. The drive rollers therefore do not form any side guides for the belt to be driven, which is aligned by an upstream side guide. Since the band only has to be drawn into the gap between the two drive rollers, the task of the known drive frame does not even have to insert the individual strips of a sheet metal strip divided into longitudinal strips into a guide comb. Only by moving the support roller forming the guide comb for the individual strips transversely to the longitudinal strip strips can the automatic threading of the strips into the guide comb be ensured.

Um mit Hilfe solcher Führungsvorrichtungen den gewünschten Verlauf der einzelnen Bandstreifen festlegen zu können, muß selbstverständlich die Stützrolle gegenüber der Längsteilanlage ausgerichtet sein. Dies ist bei einer in einem verschiebbar gelagerten Schlitten gehaltenen Stützrolle natürlich nicht von vornherein gegeben. In weiterer Ausbildung der Erfindung kann daher der Schlitten in der Arbeitslage der Stützrolle mit Hilfe einer Rasteinrichtung gegenüber dem Gestell festgestellt werden, wodurch die erforderliche Ausrichtung sichergestellt wird. Besonders einfache Konstruktionsverhältnisse ergeben sich dabei, wenn die Rasteinrichtung aus einem quer zur Schlittenbewegung verstellbaren Bolzen besteht, der in eine entsprechende Schlittenausnehmung eingreift. Über einen entsprechenden Stelltrieb kann der Schlitten mit Hilfe eines solchen Bolzens einfach und rasch gegenüber dem Gestell verriegelt werden.In order to be able to determine the desired course of the individual strip strips with the aid of such guide devices, the support roller must of course be aligned with the slitting line. This is of course not the case with a support roller held in a slidably mounted slide. In a further embodiment of the invention, the carriage can therefore be fixed in the working position of the support roller with the aid of a latching device relative to the frame, thereby ensuring the required alignment. Particularly simple constructional relationships result when the latching device consists of a bolt which is adjustable transversely to the carriage movement and which engages in a corresponding carriage recess. The slide can be locked quickly and easily with respect to the frame by means of a corresponding actuator.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Es zeigt

  • Fig. 1 eine erfindungsgemäße Vorrichtung zum Führen der einzelnen Streifen eines in Längsstreifen geteilten Blechbandes im Längsschnitt und
  • Fig. 2 diese Vorrichtung im Schnitt nach der Linie 11-11 der Fig. 1.
In the drawing, the subject of the invention is shown in one embodiment. It shows
  • Fig. 1 shows an inventive device for guiding the individual strips of a sheet metal strip divided into longitudinal strips in longitudinal section and
  • 2 shows this device in section along the line 11-11 of FIG. 1st

Die dargestellte Vorrichtung zur Führung der einzelnen Streifen 1 eines in Längsstreifen geteilten Blechbandes besteht im wesentlichen aus einem Gestell 2, in dem ein Schlitten 3 mit einer Stützrolle 4 für die Streifen 1 quer zu diesen hin- und herverschiebbar gelagert ist. Die Stützrolle 4, die in am Schlitten 3 angeordneten Lagerböcken 5 gehalten ist, trägt Scheiben 6, deren Abstand voneinander durch Distanzhülsen 7 festgelegt ist. Die Länge dieser Distanzhülsen 7 entspricht dabei der Breite des jeweiligen Bandstreifens 1, so daß durch die auf der Stützrolle 4 angeordneten Scheiben 6 ein Führungskamm für die Streifen 1 gebildet wird.The device shown for guiding the individual strips 1 of a sheet metal strip divided into longitudinal strips essentially consists from a frame 2, in which a carriage 3 with a support roller 4 for the strips 1 is mounted so that it can be moved back and forth. The support roller 4, which is held in bearing blocks 5 arranged on the carriage 3, carries disks 6, the spacing of which from one another is defined by spacer sleeves 7. The length of these spacer sleeves 7 corresponds to the width of the respective strip 1, so that a guide comb for the strips 1 is formed by the disks 6 arranged on the support roller 4.

Zur Querverschiebung des Schlittens 3 dient ein Hydraulikzylinder 8, der im Gestell 2 gelagert ist und am Schlitten 3 angreift. Auf Grund der Anordnung des Hydraulikzylinders 8 unterhalb des Schlittens 3 ergeben sich hinsichtlich der Platzausnützung besonders günstige Verhältnisse. Der Schlitten 3 ist gemäß dem Ausführungsbeispiel über die Lagerböcke 5 auf Gleitplatten 9 in den Querhäuptern 10 des Gestells 2 abgestützt, wobei zur seitlichen Führung des Schlittens Schienen 11 dienen, die in seitliche Führungsausnehmungen der Lagerböcke eingreifen.A hydraulic cylinder 8, which is mounted in the frame 2 and engages on the carriage 3, serves for the transverse displacement of the carriage 3. Due to the arrangement of the hydraulic cylinder 8 below the carriage 3, particularly favorable conditions result in terms of space utilization. According to the exemplary embodiment, the carriage 3 is supported on the bearing blocks 5 on sliding plates 9 in the transverse heads 10 of the frame 2, rails 11 serving for lateral guidance of the carriage, which engage in lateral guide recesses in the bearing blocks.

Zum Festlegen der Arbeitslage der Stützrolle 4 dient eine Rasteinrichtung 12, die aus einem quer zur Schlittenbewegung verstellbaren Bolzen 13 besteht, der über einen Zylinder 14 antreibbar ist und in eine entsprechende Schlittenausnehmung 15 eingreift. Zum Einfädeln der einzelnen Bandstreifen 1 zwischen die Scheiben 6 wird der Bolzen 13 aus der Schlittenausnehmung 15 herausgezogen, um den Schlitten 3 über den Hydraulikzylinder 8 hin- und herverschieben zu können. Bedingt durch diese Schlittenbewegung gleiten die beim Einziehen eines neuen Blechbandes allenfalls auf den Scheiben 6 aufruhenden Bandstreifen 1 von den Scheiben ab, wobei sie zwangsläufig in die gewünschte Lage zwischen den Scheiben gelangen. Das Einfädeln der Bandstreifen 1 kann daher gefahrlos und rasch durchgeführt werden.A locking device 12, which consists of a bolt 13 which is adjustable transversely to the slide movement and which can be driven via a cylinder 14 and engages in a corresponding slide recess 15, serves to fix the working position of the support roller 4. To thread the individual strip strips 1 between the disks 6, the bolt 13 is pulled out of the slide recess 15 in order to be able to push the slide 3 back and forth via the hydraulic cylinder 8. As a result of this carriage movement, the strip strips 1, which are at most resting on the discs 6 when a new sheet metal strip is drawn in, slide off the discs, inevitably reaching the desired position between the discs. The threading of the tape strips 1 can therefore be carried out safely and quickly.
