Abstract

Double suckers (1) have fixed horizontal sucker coupling (6) attached to them. Coupling is freely movable in guide (15) at end opposite to suckers. Guide is fixed to vertical rocker (9) with guide end section rotationally resting on fixed swivel axis (10). Roller (12) is freely rotationally resting on end of rocker opposite to axis (10). Suction coupling (6) is guided along tilting axis (8) of double suckers along curve contour. Suction coupling (6) is guided along tilting axis (8) of double suckers along curve contour. Curve contour overlays a further movement to the vertical and horizontal movement of the sucker coupling, which causes tilting of the lower suction surface of the suckers, so they are raised more at their front part in feed direction thus preventing tilting moment which could release sheet from suction surfaces.

Description

Die Erfindung bezieht sich auf einen Bogenvorderkantentrenner mit mehreren nebeneinander angeordneten Doppelsaugern zur taktweisen Förderung von Bogen, wobei die Doppelsauger durch ein Kurvenkoppelgetriebe angetrieben Bewegungen auf einer geschlossenen Bahn in Förderrichtung der Bogen und zurück ausführen und dabei die Doppelsauger in einem zwei Arbeitstakte aufweisenden Bewegungszyklus um einen Arbeitstakt versetzt nacheinander in den Bereich der Stapelvorderkante eines Bogenstapels zur Erfassung eines Bogens gelangen, mit einer Saugerkoppel des Kurvenkoppelgetriebes, an der ein Doppelsauger fest angeordnet ist, wobei die Saugerkoppel mit zwei Kurvengetrieben gelenkig verbunden ist, so daß der Doppelsauger im wesentlichen vertikal und horizontal bewegbar antreibbar ist.The invention relates to a sheet leading edge separator with several double suction cups arranged side by side for cyclical conveying von Bogen, the double suction cups by a cam coupling gear driven movements on a closed path in the conveying direction run the bow and back while doing the double suction in one movement cycle comprising two work cycles by one work cycle successively moves into the area of the leading edge of a stack of sheets get a sheet with a suction pad the cam coupling gear, on which a double suction cup is fixed, the suction coupling is articulated to two cam drives, so that the double suction cup can be moved essentially vertically and horizontally is drivable.

Ein derartiger Bogenvorderkantentrenner ist aus der DE 42 20 399 A1 bekannt. Da die Kurvengetriebe dieses bekannten Bogenvorderkantentrenners nur eine vertikale und eine horizontale Bewegung erzeugen können, kommt es bei der Anhubbewegung des Doppelsaugers zu einem solchen Kippen des Doppelsaugers, daß dessen untere Saugfläche an ihrem in Förderrichtung gerichteten Ende geringer angehoben wird als das in Förderrichtung hintere Ende. Durch diese Kippbewegung ist die untere Saugfläche entgegen der Erstreckung des von dem Doppelsauger auf den Bogenstapel herunterhängenden hinteren Bogenteils geneigt, so daß sich der Bogen ungewollt leicht vom Doppelsauger lösen kann. Diese Gefahr ist bei steifen Bogen wie Kartons besonders groß, da dann der Bogen mit dem größten Teil des Gewichts seines über dem Bogenstapel entgegen der Förderrichtung sich erstreckenden hinteren Bereichs ein lösendes Moment auf den vorderen vom Doppelsauger erfaßten Bereich ausübt.Such a sheet leading edge separator is known from DE 42 20 399 A1. Because the cam mechanism of this well-known leading edge separator can only produce one vertical and one horizontal movement, this occurs during the lifting movement of the double suction device Tilting the double suction cup that its lower suction surface at its in Direction of conveying end is raised less than that in the conveying direction rear end. Due to this tilting movement, the lower suction surface is contrary to the extension of the double suction on the sheet stack drooping rear arch part inclined so that the bow can easily unintentionally detach from the double suction cup. This danger is particularly large for stiff sheets such as cardboard boxes, since the sheet is then also towards most of the weight of his over the sheet stack the conveying direction extending rear area a releasing Moment on the front area covered by the double suction cup.

Aufgabe der Erfindung ist es daher einen Bogenvorderkantentrenner der eingangs genannten Art zu schaffen, der bei einfachem Aufbau ein zumindest weitgehend senkrechtes Anheben des Doppelsaugers bei gleichzeitig definiert stärkerem Anhub des in Förderrichtung vorderen Bereichs seiner unteren Saugfläche gegenüber dem hinteren Bereich ermöglicht.The object of the invention is therefore a sheet leading edge separator to create the type mentioned, which at least with a simple structure largely vertical lifting of the double vacuum cleaner at the same time defines stronger lifting of the front area in the conveying direction allows its lower suction surface opposite the rear area.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Saugerkoppel entlang einer eine Kippbewegung des Doppelsaugers um eine sich horizontal quer zur Bogenförderrichtung erstreckende Kippachse des Doppelsaugers bestimmende Kurvenkontur geführt ist. Dabei stellen die beiden Kurvengetriebe das senkrechte Anheben des Doppelsaugers und damit ein einwandfreies Überstreifen der Bogenvorderkante über einen meist auf der Stapelvorderkante aufliegenden Abstreifer sicher. This object is achieved in that the suction pad along a tilting movement of the double suction cup around itself horizontally transverse to the sheet conveying direction extending axis of the Double suction cup defining curve contour is guided. The both cam drives the vertical lifting of the double suction cup and thus a perfect slipping over the front edge of the sheet over one usually on the front edge of the stack.

Durch die Kurvenkontur wird der Vertikal- und Horizontalbewegung der Saugerkoppel eine weitere Bewegung überlagert, die ein solches Kippen der unteren Saugfläche des Doppelsaugers bewirkt, daß diese an ihrem in Förderrichtung vorderen Bereich stärker angehoben wird als an ihrem hinteren Bereich. Somit entspricht die Neigung der unteren Saugfläche des Doppelsaugers der Erstreckung des vom Doppelsauger nach hinten wegragenden Bereichs des Bogens. Ein auf den Bogen einwirkendes Kippmoment, das zum Lösen des Bogens von der Saugfläche des Doppelsaugers führen könnte, ist damit vermieden.The vertical and horizontal movement of the Suction pad superimposed another movement that such a tilting the lower suction surface of the double suction cup causes this in on Direction of conveyance is raised more in the front area than at its rear Area. Thus, the inclination corresponds to the lower suction surface of the Double suction cup of the extension of the protruding backwards from the double suction cup Area of the arch. A tilting moment acting on the bow, to release the sheet from the suction surface of the double suction cup could be avoided.

Durch die Wahl des Verlaufs der Kurvenkontur kann auch der Verlauf der Kippbewegung bestimmt werden.By choosing the course of the curve contour, the course of the Tilting movement can be determined.

In einfacher Ausbildung kann die Kurvenkontur ein Bestandteil des ersten Kurvengetriebes sein.In simple training, the curve contour can be part of the first Be cam gear.

Das erste Kurvengetriebe kann eine sich im wesentlichen horizontal erstreckende und horizontal bewegbar antreibbare Horizontalkoppel aufweisen, die mit ihrem einen Ende an der Saugerkoppel angelenkt ist, wobei vorteilhafterweise die Schwenkachse der Anlenkung der Horizontalkoppel an der Saugerkoppel die Kippachse bildet. The first cam mechanism can be essentially horizontal have horizontal couplings which can be driven and moved horizontally, which is hinged at one end to the suction coupling, wherein advantageously the pivot axis of the articulation of the horizontal coupling forms the tilt axis at the suction coupling.

Zur Erzeugung der Horizontalbewegung kann das erste Kurvengetriebe eine sich im wesentlichen vertikal erstreckende Schwinge aufweisen, die an ihrem einen Endbereich um eine feste Schwenkachse schwenkbar gelagert ist und die von einer drehbar antreibbaren Kurvenscheibe schwenkbar antreibbar ist, wobei die Horizontalkoppel mit ihrem dem Doppelsauger entgegengesetzten Endbereich in einem Abstand zur ersten Schwenkachse an der Schwinge angelenkt ist.The first cam mechanism can be used to generate the horizontal movement have a substantially vertically extending rocker which supported at one end region so as to be pivotable about a fixed pivot axis and is pivotable by a rotatable cam is drivable, the horizontal coupling with the double suction opposite end area at a distance from the first Swivel axis is articulated on the rocker.

Ist an der Schwinge eine Rolle frei drehbar gelagert, die mit ihrer radial umlaufenden Mantelfläche an der radial umlaufenden Kontur der Kurvenscheibe in Anlage ist, so wird eine Reduzierung der Reibung erreicht.Is a roller freely rotatably mounted on the rocker, with its radial circumferential surface on the radially circumferential contour of the cam in the system, a reduction in friction is achieved.

Zur Reduzierung der beweglichen Einzelteile kann die Kurvenkontur fest mit der Schwinge verbunden sein, wobei vorzugsweise die Kurvenkontur sich etwa radial von der Schwenkachse weggerichtet erstreckt.To reduce the number of moving parts, the curve contour can be fixed be connected to the rocker, preferably the curve contour extends approximately radially away from the pivot axis.

Ist die Kurvenkontur eine Führung, in der der dem Doppelsauger entgegen gesetzte Endbereich der Saugerkoppel frei bewegbar geführt ist, so erfolgt auf einfache Weise eine Bewegungsübertragung von der Kurvenkontur auf die Saugerkoppel.
Zur Erzeugung der Vertikalbewegung weist in einfacher Ausführung das zweite Kurvengetriebe eine sich im wesentlichen vertikal erstreckende Koppel auf, die von einer zweiten drehbar antreibbaren Kurvenscheibe etwa vertikal bewegbar antreibbar ist.If the curve contour is a guide in which the end region of the suction pad opposite the double suction pad is guided so as to be freely movable, then movement is transferred in a simple manner from the curve contour to the suction pad.
In order to produce the vertical movement, the second cam mechanism has, in a simple embodiment, an essentially vertically extending coupling which can be driven approximately vertically movably by a second rotatable cam.

Dabei kann die Koppel mit ihrem einen Ende an der Saugerkoppel angelenkt und an ihrem anderen Ende von der zweiten Kurvenscheibe etwa vertikal bewegbar beaufschlagbar sein.The coupling can be articulated at one end to the suction coupling and at the other end from the second cam be acted upon vertically movable.

Zur Reduzierung der Reibung ist vorteilhafterweise an der Koppel eine zweite Rolle frei drehbar gelagert, die mit ihrer radial umlaufenden Mantelfläche an der radial umlaufenden Kontur der zweite Kurvenscheibe in Anlage ist.To reduce the friction is advantageously on the coupling second roller freely rotatably mounted with its radially circumferential surface on the radial circumferential contour of the second cam in contact is.

Zur etwa vertikal frei bewegbaren Führung der Koppel ist auf einfache Weise eine mit ihrem einen Ende um eine zweite feste Schwenkachse frei schwenkbare Rollenschwinge mit ihrem anderen Ende an der Koppel angelenkt.For the approximately vertically freely movable guidance of the paddock is simple One with one end free around a second fixed pivot axis swiveling roller rocker with its other end articulated on the coupling.

Um Abweichungen von der Vertikalführung gering zu halten, ist vorzugsweise die Rollenschwinge nahe der zweiten Kurvenscheibe an der Koppel angelenkt. In order to keep deviations from the vertical guidance small, it is preferred the roller rocker near the second cam on the coupling hinged.

Eine andere vertikale Führung kann auch darin bestehen, daß die Koppel mit ihrem einen Ende an der Saugerkoppel angelenkt und an ihrem zweiten Ende von einer doppelarmigen Schwinge etwa vertikal bewegbar beaufschlagbar ist, wobei die doppelarmige Schwinge um eine zweite feste Schwenkachse frei schwenkbar ist, mit dem freien Ende ihres einen Schwingenarms am zweiten Ende der Koppel angelenkt und über eine an dem freien Ende ihres zweiten Schwingenarms frei drehbar gelagerte zweite Rolle an der radial umlaufenden Kontur der Kurvenscheibe des zweiten Kurvengetriebes in Anlage ist.Another vertical guide can also be that the coupling articulated at one end to the suction paddle and at its second The end of a double-armed swing arm can be moved approximately vertically can be acted upon, the double-armed rocker around a second fixed Swivel axis is freely pivotable, with the free end of one Swing arm articulated at the second end of the paddock and one at the free end of their second swing arm freely rotatable second roller on the radial circumferential contour of the cam disc second cam mechanism is in plant.

Eine weitere Möglichkeit der vertikalen Führung besteht darin, daß die Koppel in einer Axialführung etwa in Richtung ihrer Längsachse geführt ist.Another possibility of vertical guidance is that the Coupling guided in an axial guide approximately in the direction of its longitudinal axis is.

Ein besonders bauteilarmer Aufbau und ein besonders geringer Bauraum wird erreicht, wenn die erste und zweite Kurvenscheibe auf einer gemeinsamen drehbar antreibbaren Antriebswelle drehfest angeordnet sind.A particularly low-component construction and a particularly small installation space is achieved when the first and second cams on a common rotatably drivable drive shaft are rotatably arranged.

Der dargestellte Bogenvorderkantentrenner besteht aus mindestens zwei im Abstand nebeneinander angeordneten Einheiten, wie eine davon in Figur 1 bzw. Figur 3 dargestellt ist.The sheet leading edge separator shown consists of at least two spaced apart units, like one of them in figure 1 or 3 is shown.

Diese Einheiten weisen jeweils einen Doppelsauger 1 und 1' auf, an dem eine sich im wesentlichen horizontal erstreckende Saugerkoppel 6 fest angeordnet ist.These units each have a double suction device 1 and 1 'on which an essentially horizontally extending suction coupling 6 is arranged.

Die Saugerkoppel 6 ist an ihrem dem Doppelsauger 1 entgegengesetzten Ende in einer Führung 15 einer Kurvenkontur frei bewegbar geführt. Die Führung 15 ist fest mit einer sich im wesentlichen vertikal erstreckenden Schwinge 9 verbunden, die mit ihrem einen Endbereich um eine feste Schwenkachse 10 schwenkbar gelagert ist, wobei die Führung 15 sich etwa radial von der Schwenkachse 10 weggerichtet erstreckt. The suction coupling 6 is opposite to the double suction device 1 End in a guide 15 of a curve contour guided freely movable. The Guide 15 is fixed with a substantially vertically extending Swing arm 9 connected with its one end region around a fixed Pivot axis 10 is pivotally mounted, the guide 15 approximately extends radially away from the pivot axis 10.

An dem der Schwenkachse 10 entgegengesetzten Ende ist an der Schwinge 9 eine Rolle 12 frei drehbar gelagert, die mit ihrer radial umlaufenden Mantelfläche 13 an der radial umlaufenden Kontur 14 eine Kurvenscheibe 11 eines ersten Kurvengetriebes in Anlage ist. Zur sicheren Anlage der Rolle 12 an der Kurvenscheibe 11 ist die Schwinge 9 entsprechend von einer Feder 24 beaufschlagt.At the opposite end of the pivot axis 10 is at the Swing arm 9 a roller 12 freely rotatably mounted with its radially rotating Shell 13 on the radially circumferential contour 14 a cam 11 of a first cam mechanism is in contact. For a safe investment the rocker 9 on the cam 11, the rocker 9 is corresponding acted upon by a spring 24.

Das erste Kurvengetriebe bildet weiterhin eine sich im wesentlichen horizontal erstreckende Horizontalkoppel 7, die mit einem Ende an der Saugerkoppel 6 nahe dem Doppelsauger 1 und mit ihrem anderen Ende im mittleren Bereich der Schwinge 9 angelenkt ist und für den horizontalen Bewegungsantrieb des Doppelsaugers 1 sorgt.The first cam mechanism continues to be essentially horizontal extending horizontal coupling 7, which has one end on the suction coupling 6 near the double suction cup 1 and with its other end in middle area of the rocker 9 is articulated and for the horizontal Movement drive of the double suction device 1 ensures.

Die Schwenkachse der Anlenkung der Horizontalkoppel 7 an der Saugerkoppel 16 bildet gleichzeitig eine Kippachse 8, um die die Saugerkoppel 6 bei Bewegung ihres dem Doppelsauger 1 entgegengesetzten Endes in der Führung 15 schwenken kann und so eine Kippbewegung des Doppelsaugers 1 bewirkt.The pivot axis of the articulation of the horizontal coupling 7 on the suction coupling 16 simultaneously forms a tilt axis 8 around which the suction coupling 6 when moving their opposite end of the double suction cup 1 in the Guide 15 can pivot and so a tilting movement of the double suction cup 1 causes.

Durch die in einem Arbeitstakt drehbar antreibbaren Antriebswellen 23 der Kurvenscheibe 11 sind die Schwinge 9 und mit ihr die Horizontalkoppel 7, die Saugerkoppel 6 sowie der Doppelsauger 1 im wesentlichen horizontal bewegbar antreibbar.Due to the drive shafts 23 which can be rotated in one work cycle Cam 11 are the rocker 9 and with it the horizontal coupling 7, the suction coupling 6 and the double suction device 1 are essentially horizontal movably drivable.

Bei dem Ausführungsbeispiel der Figur 1 ist etwa im mittleren Bereich der Saugerkoppel 6 eine Koppel 16 angelenkt, die sich im wesentlichen vertikal nach unten erstreckt und an ihrem der Saugerkoppel 6 abgewandten Ende eine frei drehbar gelagerte zweite Rolle 18 trägt. Diese Rolle 18 ist mit ihrer radial umlaufenden Mantelfläche 19 an der radial umlaufenden Kontur 20 einer Kurvenscheibe 17 eines zweiten Kurvengetriebes in Anlage, wobei die zweite Kurvenscheibe 17 neben der ersten Kurvenscheibe 11 ebenfalls auf der Antriebswelle 23 drehfest angeordnet ist und die Koppel 16 und mit ihr die Saugerkoppel 6 sowie den Doppelsauger 1 im wesentlichen vertikal bewegbar antreibt. Zur sicheren Anlage der Rolle 18 an der Kontur 20 der Kurvenscheibe 17 ist die Koppel 16 entsprechend von einer Feder 25 beaufschlagt.In the embodiment of Figure 1 is approximately in the middle Suction pad 6 a coupling 16 articulated, which is substantially vertical extends downwards and on the suction pad 6 facing away End carries a freely rotatably mounted second roller 18. This role is 18 with its radially circumferential surface 19 on the radially circumferential Contour 20 of a cam 17 of a second cam mechanism in the system, the second cam 17 next to the first cam 11 is also rotatably arranged on the drive shaft 23 and the Coupling 16 and with it the suction coupling 6 and the double suction 1 in drives essentially vertically movable. For the safe installation of roll 18 on the contour 20 of the cam 17, the coupling 16 is corresponding acted upon by a spring 25.

Im Bereich der Drehachse der zweiten Rolle 18 ist das eine Ende einer Rollenschwinge 22 an der Koppel 16 angelenkt, wobei das andere Ende der Rollenschwinge 22 um eine zweite feste Schwenkachse 21 frei schwenkbar gelagert ist. In the area of the axis of rotation of the second roller 18, one end is one Roller rocker 22 articulated to the coupling 16, the other end the roller rocker 22 freely about a second fixed pivot axis 21 is pivotally mounted.

Bei dem Ausführungsbeispiel der Figur 3 ist ebenfalls die Koppel 16 mit ihrem einen Ende an der Saugerkoppel 6 angelenkt, wobei die Koppel 16 sich im wesentlichen vertikal nach unten erstreckt. An ihrem zweiten Ende ist die Koppel 16 von einer doppelarmigen Schwinge 29 etwa vertikal bewegbar beaufschlagbar, wobei die doppelarmige Schwinge 29 um eine zweite feste Schwenkachse 21 frei schwenkbar ist. Mit dem freien Ende ihres einen Schwingenarms 30 ist die doppelarmige Schwinge 29 am zweiten Ende der Koppel 16 angelenkt und über eine an dem freien Ende des zweiten Schwingenarms 31 frei drehbar gelagerte zweite Rolle 18' an der radial umlaufenden Kontur 20 der Kurvenscheibe 17 des zweiten Kurvengetriebes von einer Feder 25' beaufschlagt in Anlage gehalten.In the embodiment of Figure 3, the coupling 16 is also with one end articulated to the suction coupling 6, the coupling 16 extends substantially vertically downward. At its second end the coupling 16 can be moved approximately vertically by a double-armed rocker 29 acted upon, the double-armed rocker 29 by a second fixed pivot axis 21 is freely pivotable. With the free end their one swing arm 30 is the double-arm swing arm 29 am second end of the coupling 16 and articulated via one at the free end of the second swing arm 31 freely rotatably mounted second roller 18 ' the radially circumferential contour 20 of the cam plate 17 of the second Cam gear held by a spring 25 'held in plant.

Die ersten Kurvenscheiben 11 und zweiten Kurvenscheiben 17 der beiden nebeneinander angeordneten Einheiten gleichen Aufbaus, wie in Figur 1 und Figur 3 dargestellt, sind um 180° zueinander versetzt angeordnet. Dies führt dazu, daß innerhalb eines zwei Arbeitstakte beinhaltenden Bewegungszyklus des Bogenvorderkantentrenners der Doppelsauger 1 zuerst mit seiner unteren Saugfläche 26 den obersten Bogen 2 im Bereich der Stapelvorderkante 4 eines Bogenstapels 5 erfaßt und zumindest weitgehend senkrecht anhebt. Durch die in der Führung 15 geführte Saugerkoppel wird dabei der Doppelsauger 1 so gekippt, daß seine untere Saugfläche 26 aus ihrer zur Oberfläche des Bogenstapels 5 parallelen Lage in eine in Förderrichtung 3 vorne höhere Lage als hinten geschwenkt wird. Dabei paßt sich die Saugfläche 26 etwa dem natürlichen Erstreckungsverlauf des mit seinem hinteren Bereich noch auf den Bogenstapel 5 herunter hängenden Bogens 2 an, was dazu führt, daß der Bogen 2 sicherer von dem Doppelsauger gehalten wird und sich nicht ungewollt von der Saugfläche 26 löst.The first cams 11 and second cams 17 of the two juxtaposed units of the same structure as in FIG. 1 and Figure 3, are arranged offset by 180 ° to each other. This leads to a movement cycle involving two work cycles of the sheet leading edge separator the double suction cup 1 first with its lower suction surface 26 the top sheet 2 in the area the stack leading edge 4 of a sheet stack 5 is detected and at least largely upright. Through the suction coupling guided in the guide 15 the double suction cup 1 is tilted so that its lower one Suction surface 26 from its position parallel to the surface of the sheet stack 5 pivoted in a higher position in the direction of conveyance 3 at the front than at the rear becomes. The suction surface 26 adjusts approximately to the natural extension course the one with the rear area still on the sheet pile 5 hanging bow 2, which makes the bow 2 more secure is held by the double suction cup and not unintentionally by the suction surface 26 releases.

In dem angehobenen Zustand des Bogens gelangt die obere Saugfläche 27 des Doppelsaugers 1 in eine Ebene, in der sich auch die einen weiteren Bogen 2' tragende untere Saugfläche 26' des Doppelsaugers 1' befindet. Dieser Bogen 2' wird nun von der oberen Saugfläche 27 des Doppelsaugers 1 übernommen.In the raised state of the sheet, the upper suction surface reaches 27 of the double vacuum cleaner 1 in a plane in which there is also another Bow 2 'carrying lower suction surface 26' of the double suction device 1 '. This sheet 2 'is now from the upper suction surface 27 of the double suction cup 1 taken over.

Der an seiner oberen Saugfläche 27' bereits einen dritten Bogen 2" tragende Doppelsauger 1'bewegt sich nun in Förderrichtung 3 zu einem Bädertisch 28 und übergibt diesen Bogen 2".The one already carrying a third sheet 2 "on its upper suction surface 27 ' Double suction device 1 'now moves in the conveying direction 3 to a bath table 28 and passes this sheet 2 ".

Gleichzeitig fährt der Doppelsauger 1 über den vorderen Bereich des Bogenstapels 5 nach oben, so daß der Doppelsauger 1' sich dann unter den von dem Doppelsauger 1 angehobenen Bogen 2 über den Bogenstapel 5 bewegen und einen weiteren Bogen 2"' erfassen kann. At the same time, the double suction device 1 moves over the front area of the sheet stack 5 upwards, so that the double suction cup 1 'is then under the sheet 2 raised by the double suction device 1 over the sheet stack 5 move and can capture another sheet 2 "'.

Nun vollführt der Doppelsauger 1' die eingangs für den Doppelsauger 1 beschriebene Anhubbewegung, während der Doppelsauger 1 die eingangs beschriebene Bewegung des Doppelsaugers 1' vollführt. Now the double suction device 1 'carries out the inputs for the double suction device 1 described lifting movement, while the double suction device 1 the input described movement of the double suction device 1 'is carried out.
