Description

Die Erfindung betrifft eine Vorrichtung zum Ansammeln von Papierbogen oder dergleichen zu Stapeln, gemäß Oberbegriff des Anspruchs 1, wie sie in ähnlicher Form aus DE-A-42 24 010 bekannt ist.The invention relates to a device for accumulating Sheets of paper or the like to be stacked, according to the preamble of claim 1, as in a similar form is known from DE-A-42 24 010.

Die eingangs bezeichnete Vorrichtung dient beispielsweise dazu, in einer oder mehreren nebeneinander verlaufenden Förderbahnen aufeinanderfolgende Bogen in Stapeln anzusammeln. Unter Bogen sollen im hier vorliegenden Zusammenhang nicht nur Papierbogen, sondern auch andere flächige Artikel wie Folienabschnitte aus Kunststoff, Metall, Vliesstoffen, Papier oder dergleichen zu verstehen sein, die wie Papierbogen behandelt werden können.
Die Bogen können mit einem Querschneider von einer oder mehreren Bahnen abgetrennt und einzeln nacheinander oder in Form eines geschuppten Stromes zur Stapelablage gefördert werden.
Insbesondere bei der Verarbeitung relativ dünnen Bogenmaterials großer Nutzenbreite, wie zum Beispiel zur Herstellung von Formularbogen, kommt den Frontanrichtmitteln in Zusammenwirkung mit den Oberförderbändern eine entscheidende Bedeutung für eine postionsgerechte Ablage der Bogen im Stapel und für deren Niederhaltung in der Förderebene zu.The device described at the outset is used, for example, to collect successive sheets in stacks in one or more conveyor tracks running next to one another. In the present context, the term sheet should not only be understood to mean paper sheets, but also other flat articles such as film sections made of plastic, metal, nonwovens, paper or the like, which can be treated like paper sheets.
The sheets can be separated from one or more webs with a cross cutter and conveyed individually one after the other or in the form of a shingled stream to the stacking station.
Especially in the processing of relatively thin sheet material with a wide range of uses, such as for the production of form sheets, the front arranging means in cooperation with the upper conveyor belts are of crucial importance for a position-appropriate storage of the sheets in the stack and for their holding down in the conveyor level.

Der Erfindung liegt die Aufgabe zugrunde, insbesondere im Hinblick auf schwierige Handhabungsbedingungen des verwendeten Bogenmaterials und dessen Nutzenbreite bei einer hohen Förderleistung eine einwandfreie Stapelbildung zu gewährleisten.The invention is based, in particular With regard to difficult handling conditions of the used Sheet material and its range of benefits with a high conveying capacity to ensure proper stack formation.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1. Auf diese Weise wird eine geschlossene, d. h. von Durchbrüchen für die Oberförderbänder freibleibende vertikale Anschlagebene der Frontanrichtmittel erhalten, so daß eine formatabhängige Querverstellung der Oberförderbänder ohne Rücksichtnahme auf die Frontanrichtmittel vorgenommen werden kann.
Eine optimierte Bogenführung und Bogenablage, insbesondere im Bereich des voreilenden Bogenendes, wird nach einer Weiterbildung dadurch erreicht, daß die Bandumlenkung eine die Untertrume in spitzem Winkel umlenkende, relativ scharfe Umlenkkante aufweist.
Zweckmäßigerweise ist die Bandumlenkung als starrer, ortsfester Rundstab ausgebildet, was gegenüber einer ebenfalls denkbaren Walzenausführung mit bedeutend geringerem konstruktiven Aufwand und Platzbedarf realisiert werden kann.
Eine Anpassung der Vorrichtung auf unterschiedliche Formatbreiten wird gemäß einer zweckmäßigen Ausgestaltung am einfachsten dadurch erreicht, daß Bogenabweiser und Oberförderbänder entlang einer die Bogenumlenkung tragenden, gemeinsamen Traverse mittels einer verfahrbaren Brücke formatabhängig seitlich einstellbar sind.
Zum Erleichtern der seitlichen Verstellung ist außerdem vorgesehen, daß die Traverse an einwärtsschwenkbaren Stellmitteln angelenkt ist, so daß die Oberförderbänder während der Verstellung zugentlastet sind.This object is achieved according to the invention by the features of claim 1. In this way, a closed, ie free of breakthroughs for the upper conveyor belt vertical stop plane of the front arranging means is obtained, so that a format-dependent transverse adjustment of the upper conveyor belts can be carried out without considering the front arranging means.
An optimized sheet guidance and sheet deposit, in particular in the area of the leading sheet end, is achieved according to a further development in that the strip deflection has a relatively sharp deflecting edge which deflects the lower strands at an acute angle.
The belt deflection is expediently designed as a rigid, stationary round rod, which can be realized with significantly less design effort and space requirements than a roller design that is also conceivable.
An adaptation of the device to different format widths is most easily achieved according to an expedient embodiment in that sheet deflectors and upper conveyor belts can be adjusted laterally depending on the format by means of a movable bridge along a common traverse carrying the sheet deflection.
In order to facilitate the lateral adjustment, it is also provided that the traverse is articulated on adjusting means which can be swiveled in, so that the upper conveyor belts are relieved of tension during the adjustment.

Der mit der Erfindung erzielte Vorteil besteht darin, daß auch bei hoher Fördergeschwindigkeit der Papierbogen deren besonders kritisches voreilendes Ende im Bereich des Frontanrichters auf die Stapelablage gelenkt wird, so daß ein Stapel homogener Konfiguration erhalten wird. Darüber hinaus wird die Umstellung der Stapelablage bzw. deren zugeordnete und vorgeordnete Fördermittel in Form der Oberförderbänder auf andere Formatbreiten erheblich vereinfacht, da dabei der Frontanrichter von einer Verstellung nicht betroffen ist. The advantage achieved with the invention is that also with a high conveying speed of the paper sheets, especially critical leading end in the area of the front panel the stacking tray is steered so that a stack is more homogeneous Configuration is obtained. In addition, the changeover the stacking tray or its associated and upstream Funding in the form of the upper conveyor belts on other format widths considerably simplified, since the front converter from an adjustment is not affected.

Die Erfindung wird nachstehend anhand des in den beigefügten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.The invention is illustrated below in the attached Illustrated embodiment illustrated.

Die in Figur 1 dargestellte Bogenablagevorrichtung entspricht im Prinzip der in der DE-A-42 24 010 offenbarten Anordnung und wird im folgenden nur noch anhand von das Verständnis der Erfindungsmerkmale erleichternden Vorrichtungsbestandteilen erläutert.
Die in Figur 1 dargestellte Anordnung ist für eine mehrnutzige Ablagevorrichung konzipiert und wird in entsprechend vervielfachter Parallelanordnung innerhalb eines gemeinsamen Gestells 1 eingesetzt, von dem lediglich eine Seitenwand 2 und eine querverlaufende Traverse 3 dargestellt sind.
Innerhalb des Gestells 1 ist ein in Längsrichtung (Pfeil 4) verfahrbarer Schlitten 6 angeordnet, der sich aus Querträgern 7, 7a und Verbindungsleisten 8 zusammensetzt. Eine in Längsrichtung verlaufende Brücke 9 ist an nur auf einer Seite angedeuteten Querführungen 11 des Schlittens 6 quer verfahrbar geführt.
Der Brücke 9 ist ein Stützschlitten 12 zugeordnet, der an der Traverse 3 zusammen mit der Brücke 9 senkrecht zur Zeichenebene verstellbar ist und auf dem die Brücke in Längsrichtung 4 verschiebbar abgestützt ist.
Zum Einstellen des Schlittens 6 in Längsrichtung 4 (Papierlaufrichtung) dient ein Längsantrieb 13 und zum Einstellen der Brücke 9 in Querrichtung bzw. senkrecht zur Zeichenebene ein Querantrieb 14.
Mittig zu einer Stapelablage 16 in Form einer absenkbaren Palette gemäß Figur 2 trägt die Brücke 9 einen Seitenanrichter 17, welcher mittels eines Kreuzschlittens 18 in Papierlaufrichtung 4 beweglich auf der Brücke 9 geführt und an einem weiteren Querträger 19 quer zur Papierlaufrichtung 4 beweglich angeordnet ist.
Der Schlitten 6 trägt an einem stirnseitigen Ende einen das Längsformat der Papierbogen bestimmenden Frontanrichter 21, der an einer Brücke 22 am Querträger 7 angeordnet ist, derart, daß er sich auf der Stapelablage 16 abstützt und in seiner Höheneinstellung der jeweiligen Palettenstellung nachgeführt wird.
Die Brücke 9 und der Stützschlitten 12 tragen zwei Oberförderbänder 23, die zwei benachbarte Förderbahnen für mittels umlaufender Bandförder 24 in geschuppter Formation angeförderte, anzusammelnde Papierbogen 26 begrenzen.
Die Oberförderbänder 23 laufen über Rollen 27a bis 27d, die am längsstationären Stützschlitten 12 gelagert sind, und über Rollen 28a, 28b sowie eine eine relativ scharfe Umlenkkante bildende, starre Bandumlenkung 29 in Form eines ortsfesten Rundstabes 31 um, die an der verfahrbaren Brücke 9 gelagert sind.
Die mit der Brücke 9 längsverfahrbare Rolle 28a und die am längsstationären Stützschlitten 12 gelagerte Rolle 27a bilden einen Bandspeicher 32, der die Veränderungen der Bandlänge zwischen der Rolle 27d und dem Rundstab 31 bei Verstellungen des Schlittens 6 kompensiert.
Die Oberförderbänder 23 werden von einer gemeinsamen Antriebswalze 33 angetrieben.
Um ein störungsfreies Querverfahren der Brücke 9 mit den Oberförderbändern 23 zu gewährleisten, sind letztere von der Antriebswalze 33 abhebbar, wozu bekannte, hier nicht näher beschriebene Bandabhebemittel 34 dienen.
Dem unmittelbar an der inneren Anschlagfläche des Frontanrichters 21 verlaufenden, die Untertrume der Oberförderbänder 23 umlenkenden Rundstab 31, welcher an einer sich quer zur Papierlaufrichtung 4 erstreckenden Traverse 36 befestigt ist, ist ein die Förderebene der Papierbogen 26 in spitzem Winkel schneidendes Bogenabweisblech 37 zugeordnet, das mit Durchtrittsöffnungen 38 für die Untertrume der Oberförderbänder 23 ausgestattet ist.
Das Bogenabweisblech 37 ist gemeinsam mit den Oberförderbändern 23 mittels einer Schlittenführung 39 entlang der ortsfesten Traverse 36 verfahrbar und steht zu diesem Zweck über Mitnehmerbleche 41 und am Bogenabweisblech 37 angesetzte Mitnehmerlaschen 42 in Schleppverbindung mit der formatabhängig querverstellbaren Brücke 9. Zur Erleichterung der Querverstellung bzw. zur Entspannung der Oberförderbänder 23 am Rundstab 31 ist die Traverse 36 um eine an einem Seitenwandteil 40 befindliche, Schwenkachse 45 mittels eines an der Brücke 22 des Schlittens 6 angreifenden Schwenkzylinders 43 über ein um eine Achse 44 am Seitenwandteil 40 drehendes Drehscheibensegment 46 und eine Gelenkkoppelstange 47 nach innen von dem Frontanrichter 21 wegschwenkbar.
Das Bogenabweisblech 37 umgreift ein sich unterseitig über die gesamte Länge der Traverse 36 erstreckendes und in spitzem Winkel zur Förderebene der Papierbogen 26 angetelltes Bogenanschlagblech 48.
Durch eine zusätzliche, nicht weiter dargestellte Höheneinstellung in Richtung des Doppelpfeils 49 sowie Längseinstellung in Richtung des Doppelpfeils 51 des die Traverse 36 lagernden Seitenwandteils 40 läßt sich der Rundstab 31 relativ zum Frontanrichter 21 optimal einstellen.
Bei der Bildung eines Bogenstapels 52 auf der Stapelablage 16 werden die in geschuppter Formation zugeführten Papierbogen 26 von den Oberförerbändern 23 bis gegen den Frontanrichter 21 vorbewegt, wobei sie im Bereich der Oberförderbänder 23 durch das Bogenabweisblech 37 und außerhalb des Bereichs der Oberförderbänder 23 durch das Bogenanschlagblech 48 an ihrer voreilenden Vorderkante nach unten gegen den Bogenstapel 52 abgelenkt werden.
Alternativ oder zusätzlich zu der beschriebenen Bogenablenkung kann auch eine Blasluftbeaufschlagung der Papierbogen 26 aus dem Innenraum der Traverse 36 heraus vorgesehen sein, was durch die Pfeile 53 angedeutet ist.The sheet depositing device shown in FIG. 1 corresponds in principle to the arrangement disclosed in DE-A-42 24 010 and is explained in the following only on the basis of device components which facilitate understanding of the features of the invention.
The arrangement shown in Figure 1 is designed for a multi-use storage device and is used in a correspondingly multiplied parallel arrangement within a common frame 1, of which only a side wall 2 and a transverse cross member 3 are shown.
A carriage 6 which can be moved in the longitudinal direction (arrow 4) and is composed of cross members 7, 7a and connecting strips 8 is arranged within the frame 1. A longitudinally extending bridge 9 is guided in a transversely movable manner on transverse guides 11 of the carriage 6, which are only indicated on one side.
The bridge 9 is assigned a support slide 12 which can be adjusted on the cross member 3 together with the bridge 9 perpendicular to the plane of the drawing and on which the bridge is supported so as to be displaceable in the longitudinal direction 4.
A longitudinal drive 13 is used to adjust the slide 6 in the longitudinal direction 4 (paper running direction) and a transverse drive 14 is used to adjust the bridge 9 in the transverse direction or perpendicular to the plane of the drawing.
In the center of a stacking tray 16 in the form of a lowerable pallet in accordance with FIG. 2, the bridge 9 carries a side straightener 17, which is guided on the bridge 9 by means of a cross slide 18 in the paper running direction 4 and is movably arranged on a further cross member 19 transversely to the paper running direction 4.
The carriage 6 carries at one end a front format 21 which determines the longitudinal format of the paper sheet and which is arranged on a bridge 22 on the cross member 7 in such a way that it is supported on the stacking tray 16 and its height adjustment is adjusted to the respective pallet position.
The bridge 9 and the support carriage 12 carry two upper conveyor belts 23 which delimit two adjacent conveyor tracks for paper sheets 26 which are conveyed in a shingled formation by means of a rotating belt conveyor 24.
The upper conveyor belts 23 run over rollers 27a to 27d, which are mounted on the longitudinally stationary support carriage 12, and over rollers 28a, 28b and a rigid belt deflection 29, which forms a relatively sharp deflection edge, in the form of a stationary round bar 31, which is mounted on the movable bridge 9 are.
The roller 28a, which can be moved longitudinally with the bridge 9, and the roller 27a, which is mounted on the longitudinally stationary support slide 12, form a tape store 32, which compensates for the changes in the tape length between the roller 27d and the round rod 31 when the slide 6 is adjusted.
The upper conveyor belts 23 are driven by a common drive roller 33.
In order to ensure a trouble-free transverse movement of the bridge 9 with the upper conveyor belts 23, the latter can be lifted off the drive roller 33, for which purpose known belt lifting means 34, not described here in more detail, are used.
The round rod 31, which deflects the lower strands of the upper conveyor belts 23 and runs directly on the inner stop surface of the front converter 21 and is fastened to a crossbar 36 which extends transversely to the paper running direction 4, is assigned a sheet deflector plate 37 which cuts the conveying plane of the paper sheets 26 at an acute angle is equipped with through openings 38 for the lower strands of the upper conveyor belts 23.
The sheet deflector plate 37 can be moved together with the upper conveyor belts 23 by means of a slide guide 39 along the stationary cross member 36 and is for this purpose via driver plates 41 and driver plates 42 attached to the sheet deflector plate 37 in drag connection with the format-dependent cross-adjustable bridge 9. To facilitate the transverse adjustment or Relaxation of the upper conveyor belts 23 on the round bar 31 is the traverse 36 around a pivot axis 45 located on a side wall part 40 by means of a pivot cylinder 43 engaging on the bridge 22 of the carriage 6 via a turntable segment 46 rotating about an axis 44 on the side wall part 40 and an articulated coupling rod 47 can be pivoted away from the inside of the front converter 21.
The sheet deflecting plate 37 engages around a sheet stop plate 48 which extends on the underside over the entire length of the cross member 36 and is set at an acute angle to the conveying plane of the paper sheets 26.
The round rod 31 can be optimally adjusted relative to the front plate 21 by an additional height adjustment in the direction of the double arrow 49 and a longitudinal adjustment in the direction of the double arrow 51 of the side wall part 40 supporting the cross member 36.
When a sheet stack 52 is formed on the stacking tray 16, the paper sheets 26 fed in shingled formation are advanced from the upper conveyor belts 23 to the front converter 21, being in the area of the upper conveyor belts 23 by the sheet deflector plate 37 and outside the area of the upper conveyor belts 23 by the sheet stop plate 48 are deflected downward at their leading leading edge against the sheet stack 52.
As an alternative or in addition to the described sheet deflection, blowing air can also be applied to the paper sheets 26 from the interior of the cross member 36, which is indicated by the arrows 53.
