Definitions
- the present invention relates to angled shears with a feed table and associated longitudinal and transverse shears. There are also longitudinal and transverse feeds, as well as guide devices, together with a rotating device arranged above the feed table.
- Angled scissors with an L-shaped table are already known, which angular scissors have a longitudinal knife and a transverse knife, as well as feed means arranged between them in the longitudinal and transverse directions.
- the purpose of such angled scissors is to quickly and reliably dismantle metal sheets into individual blanks.
- Such a device according to the preamble of claim 1 is known for example from GB-A-2001272.
- an angle shear which allows the automatic cutting of metal sheets from stacks and can be used universally for large panels cut precisely at right angles, as well as for strips and smaller boards.
- a high cutting accuracy should be guaranteed.
- the cutting of boards should be possible in one pass.
- the angle scissors of the type mentioned at the outset which are suitable for this purpose are defined by the features listed in claim 1.
- a stacking device can expediently be provided both behind the longitudinal shears and behind the cross shears be, wherein at least one stacking device consists of a forward and backward movable conveyor belt which can be lowered and raised with the scissors movement.
- the longitudinal direction is designated with the Y direction and the transverse direction with the X direction.
- the angular shear has a longitudinal shear 1 extending in the Y direction and a transverse shear perpendicular to it, the longitudinal shear having a longitudinal knife 3 and the transverse shear having a transverse knife 4.
- the longitudinal shear 1 and the cross shear 2 have a common hydraulic control 5 and are equipped with a scrap box 6 and 7, respectively.
- the longitudinal scissors 1 and the cross scissors 2 are jointly provided with a feed table 8, on which, at the end remote from the longitudinal scissors 1, there is a lifting platform 9. Above the lift a suction head 11 can be raised and lowered and rotated on a suction head carriage 10.
- the suction head carriage is slidably arranged on a cross member 34 above the feed table 8.
- the parts 10, 11 and 34 together form a feeder for the metal sheet, which is directed in the stack by side and front stops, are arranged on the lifting platform 9.
- the lifting platform 9 is designed in a known manner in such a way that it automatically goes up so far that the uppermost plate comes to lie on the level of the feed table 8.
- the lowerable and rotatable suction head 11 grips the uppermost sheet metal plate on one side, bends the sheet metal slightly and lifts, after which the suction head slide 10 moves forward in the Y direction and pulls the sheet metal onto the feed table 8.
- the feed table 8 is equipped with ball rollers (not shown).
- the table 8 is provided with continuous grooves 12 which extend in the Y direction and in which Y-pliers 13 are arranged so that they can be lowered and raised. These can be used to grasp the edge of a sheet of metal. However, it is also possible for these Y pliers to jointly form a stop if the metal sheet is aligned in the X direction. Below the table 8 there is a crossbar 14 on which the Y-tongs are fastened and lowered. The crossbar 14 is arranged to be displaceable in the Y direction and forms the Y feed for the Y pliers 13. The entire control is carried out from a control panel 15.
- X pliers 16 are provided above the table surface opposite the cross shear, which are also arranged on a common longitudinal beam 17 so as to be displaceable and positionable in the X direction.
- the pliers 16 are located above the table surface 8 and can be raised and lowered accordingly to grip the sheet metal piece.
- the longitudinal bar 17 is displaced along a guide bar 18 on which corresponding slide rails are arranged.
- a conveyor belt 19 which runs in the Y direction and is guided over deflection shafts 20, 21.
- the conveyor belt 19 is also connected to the pivotable housing 22 of the longitudinal knife 3.
- the housing 22 pivots around the shaft 23, the arrangement being such that during the cutting movement, ie when pivoting counterclockwise, the conveyor belt 19 is also pivoted in the same sense and is thereby sunk under the table surface.
- the upper run of the conveyor belt 19 is at the same height as the upper table surface of the feed table 8.
- the conveyor belt 19 is pivoted downward with its end facing the longitudinal knife 3 in the manner described.
- a stacker 24 At the other end of the conveyor belt is a stacker 24 with transverse conveyor rollers, the axes of which extend in the Y direction (not shown).
- a conveyor belt 25 is also located behind the transverse knife 4 of the transverse shear 2, the upper run of which is sunk relative to the table surface.
- An adjustable, known stop device 26 is provided in the table surface. Behind the conveyor belt 25 there is in turn a lifting platform 27 which is equipped with a roller conveyor 28. Above the runway 28 there is a stop 29 which can be adjusted with the aid of a guide 30 on a guide rod 31 which extends in the X direction.
- Retractable side stops 32 and 33 are also arranged on the surface of the feed table 8.
- the side stops 32, 33 are aligned and distributed within a surface in the longitudinal and transverse feed directions X and Y, which surface is delimited by the longitudinal scissors 1, cross scissors 2 and by the Y pliers 13 and the X pliers 16.
- the side stops can be raised from the lowered position to the position of use, each have a roller against which the edge of the metal sheet to be guided comes into contact during use, the roller being preceded by a further swiveling pressure roller and a counter-holder arranged underneath. This pressure roller and the counter bracket form a clamping device for the metal sheet. In the one position of the pressure roller, the sheet metal plate can be moved between it and the counter-holder and in the second position the metal plate is clamped between the counter-holder and the pressure roller.
- the row-by-side arrangement of the side stops ensures that the metal sheets can be guided along different side stops depending on their size and intended use, so that the formation of several stacks of sheet metal sections next to one another is made possible.
- the sheet metal sections can thus be stored separately in several stacks and manipulation with the sheet metal sheets is also facilitated.
- the turning device which can be moved lengthways and crossways above the work table and is equipped with the suction head, further facilitates manipulation.
- the angle shear described has a sheet metal feed system which, as described, consists of a feed slide equipped with tongs in the X and Y directions.
- the pliers are actuated hydraulically in a known manner and the pliers for the Y feed can be lowered below the table surface, while the pliers for the XV feed can be lifted up, so that the pliers can cross without collision in the lowered or raised position . If the table has to be rotated by the suction head, the pliers are in the lowered or raised position during this rotation, so that the table can be rotated freely.
- the sheet of metal with the suction head 11 is placed on the feed table 8 with the aid of the suction head carriage 10.
- the Y-tongs 13 then grip the corresponding sheet metal edge and push the sheet under the longitudinal knife 3 in the direction of the conveyor belt 19 until the strip width to be cut between the knife base and the tongs base is reached.
- This is followed by longitudinal cutting, whereupon the cut strip is returned along the raised side stops 22, 23 with the aid of the conveyor belt, which is now operated in the opposite direction.
- the X-tongs are used and grasp the strip, whereupon the cross-shear feeds in the X-direction.
- the side stops 22, 23 in turn form a correct guide.
- the boards are then cut and ejected onto the stacking station.
- the Y-tongs move forward again, grasp the rest of the sheet, which is fed to the Y-tongs by the reverse conveyor belt.
- the side stops 32 grip and guide on both sides right and left, while the side stops 33 guide or grip only on one side.
- Boards are also cut in one pass, with the cut strip being shifted from the Y feed into one of the three liftable side guides 32, 33 after the longitudinal cut.
- the side guide heads are equipped with guide rollers and pneumatic pinch rollers, which are used to advance the strip Guide the strip in the direction of the transverse shear and press it against the side guide rollers so that exactly right-angled cuts are made.
- the Y-pliers are loosened and lowered under the table surface, while the strip is gripped by the X-pliers required according to the strip width and pushed through the cross-cutters to make the board cuts.
- the side guides are arranged at three different distances perpendicular to the longitudinal shears and allow the ejection of boards at three different locations that can be selected by the control system, so that depending on the board format it is possible to create up to three stacks side by side.
- the conveyor belt behind the longitudinal scissors also serves as a stacking device and conveys the cut strips to the rear, or the rest of the table to the front. Since the conveyor belt is automatically lowered when cutting, space is created for the descending top knife and the sheet metal sections conveyed to the rear for stacking are stacked on the lift equipped with the runway. The height of the lift can be adjusted automatically, whereby after reaching the permissible stack height, the lift is automatically lowered and the stack is extended.
- the stacking device of the cross shear also consists of the height-adjustable conveyor belt with sheet metal supports that can be raised from it, as well as the downstream stacker with roller conveyor and height-adjustable stacking platform.
- the stacking platform can be lifted from a carriage that can be lifted in the vertical direction there are a number of forks that collect the sheet metal sections behind the conveyor belt according to a minimum fall height.
- the forks are automatically adjusted as the stack grows. If the stack height is reached, the forks are lowered between the rollers of the runway, so that the stack can then be extended either directly or on a pallet.

In der Fig. 1 der Zeichnung ist die Längsrichtung mit Y-Richttung und die Querrichtung mit X-Richtung bezeichnet. Die Winkelschere weist eine sich in der Y-Richtung erstreckende Längsschere 1 und eine dazu senkrecht stehende Querschere auf, wobei die Längsschere einen Längsmesser 3 und die Querschere einen Quermesser 4 besitzt. Die Längsschere 1 und die Querschere 2 weisen eine gemeinsame hydraulische Steuerung 5 auf und sind mit je einem Schrottkasten 6 bzw. 7 ausgerüstet. Die Längsschere 1 und die Querschere 2 sind gemeinsam mit einem Zufuhrtisch 8 versehen, an welchem sich, am der Längsschere 1 abgekehrten Ende eine Hebebühne 9 befindet. Oberhalb der Hebebühne ist auf einem Saugerkopfschlitten 10 ein Saugerkopf 11 hebund senkbar und drehbar angeordnet. Der Saugerkopfschlitten ist auf einer Traverse 34 oberhalb des Zufuhrtisches 8 verschiebbar angeordnet. Die Teile 10, 11, und 34 bilden zusammen einen Zubringer für die Blechtafel, welche im Stapel durch Seiten- und Frontanschläge gerichtet, auf der Hebebühne 9 angeordnet werden. Die Hebebühne 9 ist in bekannter Weise so ausgebildet, dass sie jeweils automatisch so weit hoch geht, dass das oberste Blech auf die Höhe des Zufuhrtisches 8 zu liegen kommt. Der senkbare und drehbare Saugerkopf 11 fasst auf einer Seite die oberste Blechtafel, biegt das Blech leicht ab und hebt an, wonach der Saugerkopfschlitten 10 in der Y-Richtung vorfährt und das Blech auf den Zufuhrtisch 8 zieht. Zu diesem Zwecke ist der Zufuhrtisch 8 mit Kugelrollen bestückt (nicht gezeichnet).In FIG. 1 of the drawing, the longitudinal direction is designated with the Y direction and the transverse direction with the X direction. The angular shear has a longitudinal shear 1 extending in the Y direction and a transverse shear perpendicular to it, the longitudinal shear having a
Der Tisch 8 ist mit durchgehenden, sich in der Y-Richtung erstreckenden Rillen 12 versehen, in welchen absenkbar und hochhebbar Y-Zangen 13 angeordnet sind. Mit diesen kann der Rand einer Blechtafel ergriffen werden. Es ist aber auch möglich, dass diese Y-Zangen gemeinsam einen Anschlag bilden, wenn die Blechtafel in der X-Richtung ausgerichtet wird. Unterhalb des Tisches 8 befindet sich ein Querbalken 14, auf welchem die Y-Zangen heb- und senkbar befestigt sind. Der Querbalken 14 ist in der Y-Richtung verschiebbar angeordnet und bildet den Y-Vorschub für die Y-Zangen 13. Die ganze Steuerung erfolgt von einem Steuerungspult 15 aus.The table 8 is provided with
Für den X-Vorschub sind oberhalb der Tischfläche gegenüber der Querschere vier X-Zangen 16 vorgesehen, welche ebenfalls auf einem gemeinsamen Längsbalken 17 in der X-Richtung verschiebbar und positionierbar angeordnet sind. Bei der Verschiebung des Längsbalkens 17 in der X-Richtung befinden sich die Zangen 16 oberhalb der Tischoberfläche 8 und können zum Ergreifen des Blechstückes entsprechend gehoben und gesenkt werden. Die Verschiebung des Längsbalkens 17 erfolgt entlang eines Führungsbalkens 18, auf welchem entsprechende Gleitschienen angeordnet sind.For the X feed, four
Direkt hinter der Schneidstelle des Längsmessers 3 befindet sich ein Förderband 19, welches in der Y-Richtung verläuft und über Umlenkwellen 20, 21 geführt ist. Das Förderband 19 ist ferner mit dem schwenkbaren Gehäuse 22 des Längsmessers 3 vebunden. Bei der Schnittbewegung führt das Gehäuse 22 eine Schwenkung um die Welle 23 aus, wobei die Anordnung so getroffen ist, dass bei der Schnittbewegung, d.h. bei der Schwenkung im Gegenuhrzeigersinne, das Förderband 19 ebenfalls in gleichem Sinne verschwenkt und dabei unter die Tischoberfläche versenkt wird. In der dargestellten Ausgangsstellung befindet sich das obere Trum des Förderbandes 19 in der gleichen Höhe wie die obere Tischfläche des Zufuhrtisches 8. Während des Schneidvorganges wird in der beschriebenen Weise das Förderband 19 mit seinem, dem Längsmesser 3 zugekehrten Ende, nach unten verschwenkt. Am anderen Ende des Förderbandes befindet sich ein Stapler 24 mit Quer-Förderrollen, deren Achsen sich in der Y-Richtung erstrecken (nicht gezeigt).Directly behind the cutting point of the
Hinter dem Quermesser 4 der Querschere 2 befindet sich ebenfalls ein Förderband 25, dessen oberer Trum gegenüber der Tischoberfläche versenkt ist. In der Tischoberfläche ist eine einstellbare, an und für sich bekannte Anschlagvorrichtung 26 vorgesehen. Hinter dem Förderband 25 ist wiederum eine Hebebühne 27 vorhanden, welche mit einer Rollbahn 28 ausgerüstet ist. Oberhalb der Rollbahn 28 ist ein Anschlag 29 vorgesehen, welcher mit Hilfe einer Führung 30 auf einer Führungsstange 31 verstellbar ist, die in der X-Richtung verläuft.A
An der Oberfläche des Zufuhrtisches 8 sind ferner versenkbare Seitenanschläge 32 und 33 angeordnet. Die Seitenanschläge 32, 33 sind innerhalb einer Fläche in der Längs- und Quervorschubrichtung X und Y ausgerichtet und verteilt, welche Fläche durch die Längsschere 1, Querschere 2 und durch die Y-Zangen 13, sowie die X-Zangen 16 begrenzt ist. Die Seitenanschläge sind aus der versenkten Stellung in die Gebrauchsstellung hochhebbar, weisen je eine Rolle auf, gegen welche im Gebrauch die zu führende Kante der Blechtafel zur Anlage kommt, wobei die Rolle eine weitere schwenkbare Andrückrolle und eine darunter angeordnete Gegenhalterung vorgelagert ist. Diese Andrückrolle, sowie die Gegenhalterung bilden eine Klemmvorrichtung für die Blechtafel. In der einen Stellung der Andrückrolle kann die Blechtafel zwischen dieser und der Gegenhalterung beweglich geführt und in der zweiten Stellung wird die Blechtafel zwischen der Gegenhalterung und der Andrückrolle eingeklemmt werden.Retractable side stops 32 and 33 are also arranged on the surface of the feed table 8. The side stops 32, 33 are aligned and distributed within a surface in the longitudinal and transverse feed directions X and Y, which surface is delimited by the longitudinal scissors 1,
Durch die reihenweise Anordnung der Seitenanschläge wird erreicht, dass die Blechtafeln je nach Grösse und Verwendungszweck entlang von verschiedenen Seitenanschlägen geführt werden können, so dass die Bildung von mehreren Stapeln von Blechabschnitten nebeneinander ermöglicht wird. Die Blechabschnitte können also örtlich getrennt in mehreren Stapeln untergebracht werden und das Manipulieren mit den Blechtafeln wird ebenfalls erleichtert.The row-by-side arrangement of the side stops ensures that the metal sheets can be guided along different side stops depending on their size and intended use, so that the formation of several stacks of sheet metal sections next to one another is made possible. The sheet metal sections can thus be stored separately in several stacks and manipulation with the sheet metal sheets is also facilitated.
Eine weitere Erleichterung des Manipulierens bildet die Drehvorrichtung, welche oberhalb dem Arbeitstisch in Längs- und Querrichtung vershiebbar ist und mit dem Saugerkopf ausgerüstet ist.The turning device, which can be moved lengthways and crossways above the work table and is equipped with the suction head, further facilitates manipulation.
Die beschriebene Winkelschere weist ein Blechvorschubsystem auf, welches wie beschrieben, aus je einem zangenbestückten Vorschubschlitten in X- und Y-Richtung besteht. Die Betätigung der Zangen erfolgt in bekannter Weise hydraulisch und die Zangen für den Y-Vorschub sind nach unten unter die Tischoberfläche absenkbar, während die Zangen für den X-V Vorschub hochhebbar sind, so dass in abgesenkter bzw. gehobener Stellung der Zangen diese ohne Kollision kreuzen können. Falls die Tafel durch den Saugerkopf gedreht werden muss, so befinden sich die Zangen während dieser Drehung in abgesenkter bzw. hochgehobener Stellung, so dass die Tafel frei gedreht werden kann.The angle shear described has a sheet metal feed system which, as described, consists of a feed slide equipped with tongs in the X and Y directions. The pliers are actuated hydraulically in a known manner and the pliers for the Y feed can be lowered below the table surface, while the pliers for the XV feed can be lifted up, so that the pliers can cross without collision in the lowered or raised position . If the table has to be rotated by the suction head, the pliers are in the lowered or raised position during this rotation, so that the table can be rotated freely.
Zum Schneiden von Platinen in einem Durchlauf, wird die Blechtafel mit dem Saugerkopf 11 mit Hilfe des Saugerkopfschlittens 10 auf den Zuführtisch 8 gelegt. Anschliessend ergreifen die Y-Zangen 13 die entsprechende Blechkante und schieben das Blech so weit unter das Längsmesser 3 Richtung Förderband 19, bis die zu schneidende Streifenbreite zwischen Messer- und Zangengrund erreicht ist. Anschliessend erfolgt das Längsschneiden, worauf der geschnittene Streifen mit Hilfe des Förderbandes, welches nun in umgehrter Richtung betätigt wird, entland der hochgestellten Seitenanschläge 22, 23 zurückgeführt wird. Nachdem die Y-Zangen gelöst und abgesenkt wurden, kommen die X-Zangen zum Einsatz und fassen den Streifen, worauf der Vorschub in der X-Richtung durch die Querschere erfolgt. Die Seitenanschläge 22, 23 bilden wiederum eine korrekte Führung. Anschliessend werden die Platinen geschnitten und auf die Stapelstation ausgeworfen. Gleichzeitig fahren die Y-Zangen wieder nach vorne, fassen das Restblech, welches vom rückwärtslaufenden Förderband den Y-Zangen zugeführt wird. Es sei ferner noch erwähnt, dass zwei Arten von Seitenanschlägen zum Einsatz kommen. Die Seitenanschläge 32 fassen und führen beidseitig rechts und links, während die Seitenanschläge 33 nur auf einer Seite führen bzw. fassen.To cut boards in one pass, the sheet of metal with the
Auch Platinen werden in einem Durchlauf geschnitten, wobei nach dem Längsschnitt der abgeschnittene Streifen vom Y-Vorschub in eine der drei hebbaren Seitenführungen 32, 33 verschoben wird. Die Seitenführungsköpfe sind mit Führungsrollen und pneumatischen Klemmrollen versehen, die beim Vorschieben des Streifens in Richtung Querschere den Streifen führen und gegen die Seitenführungsrollen andrücken, so dass genau rechtwinklige Schnitte entstehen. Nach dem Einführen in die Seitenführung werden die Y-Zangen gelöst und unter die Tischoberfläche abgesenkt, wobei gleichzeitig der Streifen von den entsprechend der Streifenbreite benötigten X-Zangen ergriffen und durch die Querschere geschoben wird, zur Ausführung der Platinenschnitte. Die Seitenführungen sind in drei verschiedenen Abständen senkrecht zur Längsschere angeordnet und ermöglichen das Auswerfen von Platinen an drei verschiedenen, von der Steuerung auswählbaren Orten, so dass es je nach Platinenformat möglich ist, bis drei Stapel nebeneinander zu erzeugen.Boards are also cut in one pass, with the cut strip being shifted from the Y feed into one of the three liftable side guides 32, 33 after the longitudinal cut. The side guide heads are equipped with guide rollers and pneumatic pinch rollers, which are used to advance the strip Guide the strip in the direction of the transverse shear and press it against the side guide rollers so that exactly right-angled cuts are made. After insertion into the side guide, the Y-pliers are loosened and lowered under the table surface, while the strip is gripped by the X-pliers required according to the strip width and pushed through the cross-cutters to make the board cuts. The side guides are arranged at three different distances perpendicular to the longitudinal shears and allow the ejection of boards at three different locations that can be selected by the control system, so that depending on the board format it is possible to create up to three stacks side by side.
Das Förderband hinter der Längsschere dient gleichzeitig als Stapeleinrichtung und förder die abgeschnittenen Streifen nach hinten, oder den Tafelrest nach vorne. Da das Förderband beim Schneiden automatisch gesenkt wird, entsteht Raum für das niedergehende Obermesser und die nach hinten zum Stapeln geförderten Blechabschnitte werden auf der Rollbahn bestückten Hebebühne gestapelt. Die Hebebühne ist automatisch in der Höhe einstellbar, wobei nach Erreichen der zulässigen Stapelhöhe die Hebebühne automatisch abgesenkt und der Stapel ausgefahren wird. Die Stapeleinrichtung der Querschere besteht ebenfalls aus dem in der Höhe feststehenden Förderband mit daraus hochfahrbaren Blechstützen, sowie aus dem nachgeschalteten Stapler mit Rollbahn und höhenverstellbarer Stapelbühne. Die Stapelbühne kann aus einem in vertikaler Richtung hebbaren Schlitten mit einer Anzahl Gabeln bestehen, die entsprechend einer Mindestfallhöhe die Blechabschnitte hinter dem Förderband auffangen. Die Gabeln werden dabei automatisch entsprechend dem Anwachsen des Stapels verstellt. Wird die Stapelhöhe erreicht, so erfolgt eine Absenkung der Gabeln zwischen die Rollen der Rollbahn, so dass der Stapel dann entweder direkt oder auf einer Palette seitlich ausgefahren werden kann.The conveyor belt behind the longitudinal scissors also serves as a stacking device and conveys the cut strips to the rear, or the rest of the table to the front. Since the conveyor belt is automatically lowered when cutting, space is created for the descending top knife and the sheet metal sections conveyed to the rear for stacking are stacked on the lift equipped with the runway. The height of the lift can be adjusted automatically, whereby after reaching the permissible stack height, the lift is automatically lowered and the stack is extended. The stacking device of the cross shear also consists of the height-adjustable conveyor belt with sheet metal supports that can be raised from it, as well as the downstream stacker with roller conveyor and height-adjustable stacking platform. The stacking platform can be lifted from a carriage that can be lifted in the vertical direction there are a number of forks that collect the sheet metal sections behind the conveyor belt according to a minimum fall height. The forks are automatically adjusted as the stack grows. If the stack height is reached, the forks are lowered between the rollers of the runway, so that the stack can then be extended either directly or on a pallet.
