Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, bei einer gattungsgemäßen Vorrichtung die Schüttelwirkung der Trennbleche zu verbessern.The invention has for its object to improve the shaking effect of the partition plates in a generic device.
Diese Aufgabe wird dadurch gelöst, daß an dem im Maschinengestell befestigten Halter eine Halteplatte über Gummielemente schwingungsentkoppelt befestigt ist, an der das Trennblech und ein Vibrator starr aufgehängt sind.This object is achieved in that on the holder fastened in the machine frame, a holding plate is fastened in a vibration-decoupled manner via rubber elements, on which the separating plate and a vibrator are rigidly suspended.
Diese Konstruktion hat den Vorteil, daß der Vibrator sich beim Schwingen nur an dem Stapel selbst abstützen kann, somit die gesamte Schwingungsenergie an den Stapel abgegeben wird. Dies erhöht die Wirkung des Vibrators erheblich.This construction has the advantage that the vibrator can only be supported on the stack itself when vibrating, so that the entire vibrational energy is delivered to the stack. This significantly increases the effect of the vibrator.
Als weiterer Vorteil tritt hinzu, daß von den Vibrator keine Schwingungen an andere Teile der Stapelvorrichtung abgegeben werden. So wird die übrige Aufhängung des Trennblechs weniger belastet.Another advantage is that the vibrator does not emit vibrations to other parts of the stacking device. So the rest of the suspension of the divider is less stressed.
Die Unteransprüche enthalten bevorzugte, da besonders vorteilhafte Ausgestaltungen der Erfindung:The subclaims contain preferred, since particularly advantageous, embodiments of the invention:
Nach Patentanspruch 2 ist das Trennblech lösbar an der Halteplatte befestigt. Es läßt sich somit ohne Demontage des Vibrators auswechseln.According to claim 2, the partition is releasably attached to the holding plate. It can therefore be replaced without dismantling the vibrator.
Die Ausgestaltung des Halters als heb- und senkbare Halteplatte nach Patentanspruch 3 ermöglicht es, das Trennblech mit dem Vibrator in eine inaktive Position oberhalb des Stapels anzuheben, falls es nicht benötigt wird. Bei der besonders vorteilhaften Ausgestaltung nach Patentanspruch 4 sind an der Halteplatte auch eine Ausstoßrolle und ein Trennschuh befestigt, so daß alle auf eine Bogenlängskante einwirkenden Stapelbildungselemente mit einem einzigen gemeinsamen Hebeantrieb angehoben und abgesenkt werden können.The design of the holder as a lifting and lowering holding plate according to claim 3 makes it possible to raise the separating plate with the vibrator into an inactive position above the stack if it is not required. In the particularly advantageous embodiment according to claim 4, an ejection roller and a separating shoe are also attached to the holding plate, so that all stacking elements acting on a longitudinal edge of the sheet can be raised and lowered with a single common lifting drive.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
Die in den Figuren dargestellte Stapelvorrichtung dient zum Stapeln von kontinuierlich in Schuppenform angeförderten Papier- oder Kartonbögen 1 , die in einer Querschneidemaschine hergestellt wurden. Die Bögen 1 werden dem Stapelbereich von einem als Bandförderer ausgebildeten Zuförderer 2 zugefördert, der vertikal ortsfest in einer Höhe oberhalb der maximalen Stapelhöhe über den Boden angeordnet ist. Die Stapel 3 werden auf Paletten 4 gebildet, die auf einer Ablageplattform 5 liegen. Die Ablageplattform 5 ist im Gestell der Stapelvorrichtung bis in den Bereich der Zuförderebene der Bögen 1 anhebbar und bis in den Flurbereich absenkbar aufgehängt. Das Gestell der Vorrichtung besteht aus zwei einlaufseitigen Ständern 6 und zwei aus- laufseitigen Ständern 7, die außerhalb der Arbeitsbreite an beiden Maschinenlängsseiten angeordnet und an ihrem oberen Enden über Längsträger 8 und Querträger miteinander verbunden sind. Die Ständer 6, 7 begrenzen den Stapelbereich.The stacking device shown in the figures serves for stacking sheets of paper or cardboard 1 which are continuously conveyed in the form of scales and which were produced in a cross-cutting machine. The sheets 1 are conveyed to the stacking area by a feed conveyor 2 designed as a belt conveyor, which is arranged vertically stationary at a height above the maximum stacking height above the floor. The stacks 3 are formed on pallets 4 which lie on a storage platform 5. The storage platform 5 can be raised in the frame of the stacking device into the area of the feed plane of the sheets 1 and can be lowered into the corridor area. The frame of the device consists of two inlet-side stands 6 and two outlet-side stands 7, which are arranged outside the working width on both longitudinal sides of the machine and are connected to one another at their upper ends by longitudinal members 8 and cross members. The stands 6, 7 limit the stacking area.
Im Bereich der Zuförderebene der Bögen 1 sind verschiedene Elemente für ein störungsfreies Fördern der Bögen 1 in den Stapelbereich und deren kantengenaue Ablage auf den Stapel 3 angeordnet. Es werden bis zu vier Stapel 3 gleichzeitig nebeneinander gebildet. Die Papier- oder Kartonbahn, aus denen die Bögen 1 hergestellt werden, wird daher in der Querschneidemaschine vor dem Querschneiden zusätzlich durch eine entsprechende Anzahl von Längsschnitten in Einzelbahnen aufgeteilt.In the area of the feed plane of the sheets 1, various elements are arranged for a trouble-free feeding of the sheets 1 into the stack area and their edge-accurate placement on the stack 3. Up to four stacks 3 are formed side by side at the same time. The paper or cardboard web from which the sheets 1 are produced is therefore additionally divided into individual webs in the cross cutting machine before the cross cutting by a corresponding number of longitudinal cuts.
Als Stapelbildüngselemente enthält die Vorrichtung ein sich quer über die Arbeitsbreite erstreckendes Anschlagbrett 9, an dem die Bogenvorderkanten ausgerichtet werden. Damit die Position des Anschlagbretts 9 in Längsrichtung der jeweiligen Bogenlänge angepaßt werden kann, ist es im hinteren Stapelbereich längsverschiebbar aufgehängt. Hinter dem Zuförderer 2 sind quer über die Arbeitsbreite mit Abstand voneinander mehrere Ausstoßrollen 10 angeordnet, von denen die Bögen 1 in den Stapelbereich übergeben werden. In Bogenlaufrichtung unmittelbar hinter den Ausstoßrollen 10 sind Trennschuhe 11 angeordnet, von denen die Längskanten zweier benachbarter Bögen 1 hochgebogen werden. Die Krümmung eines Bogens 1 an seinen Längskanten führt zu einer sogenannten Schüsselung, die den Bogen 1 stabilisiert und zugleich eine sichere Trennung zwei benachbarter Bögen '1 bewirkt.As stack formation elements, the device contains a stop board 9 which extends across the working width and on which the leading edges of the sheet are aligned. So that the position of the stop board 9 in the longitudinal direction of the respective sheet length can be adjusted, it is suspended in the rear stacking area so as to be longitudinally displaceable. Behind the feed conveyor 2 several discharge rollers 10 are arranged across the working width at a distance from one another, of which the sheets 1 are transferred into the stacking area. Separating shoes 11 are arranged in the sheet running direction directly behind the ejection rollers 10, from which the longitudinal edges of two adjacent sheets 1 are bent up. The curvature of a sheet 1 on its longitudinal edges leads to a so-called keying, which stabilizes the sheet 1 and at the same time brings about a secure separation of two adjacent sheets ' 1.
Hinter jedem Trennschuh 11 ist ein Trennblech 12 angeordnet, daß sich senkrecht und in Bogenlaufrichtung erstreckt. Die Trennbleche 12 haben die Aufgabe, für eine kanten-genaue Ablage der Bögen 1 auf den Stapel die Bögen 1 seitlich zu führen und aus-zurichten. Sie sind daher im Stapelbereich jeweils zwischen zwei Stapeln 3 und an den beiden äußeren Längskanten der äußeren Stapel 3 angeordnet. Die Trennbleche 12 sind jeweils an einem im Maschinengestell befestigten Halter aufgehängt und mit einem pneumatischen oder elektromotorischen Vibrator 13 als Schüttelantrieb verbunden, von dem sie mit einer Frequenz von einigen Hertz geschüttelt werden. Die Aufhängung eines Trennblechs 12 mit einem Vibrator 13 ist in den Figuren 2 und 3 detaillierter und in Figur 4 schematisch dargestellt:A separating plate 12 is arranged behind each separating shoe 11 and extends vertically and in the direction of sheet travel. The separating plates 12 have the task of laterally guiding and aligning the sheets 1 for an edge-accurate depositing of the sheets 1 onto the stack. They are therefore arranged in the stack area between two stacks 3 and on the two outer longitudinal edges of the outer stack 3. The separating plates 12 are each suspended from a holder fastened in the machine frame and connected to a pneumatic or electromotive vibrator 13 as a shaking drive, from which they are shaken at a frequency of a few Hertz. The Suspension of a partition plate 12 with a vibrator 13 is shown in more detail in FIGS. 2 and 3 and schematically in FIG. 4:
Ein Trennblech 12 hängt gemeinsam mit den Ausstoßrollen 10 und den Trennschuh 11 an einer als Halter dienenden Halteplatte 14, die am Ende von zweiA partition plate 12 hangs together with the ejection rollers 10 and the separation shoe 11 on a holding plate 14 serving as a holder, which at the end of two
Führungsstangen 15 befestigt ist. An ihrem oberen Ende sind die Führungsstangen 15 an einem an einer Quertraverse querverschiebar gelagerten Schlitten 16 befestigt. Eine ebenfalls am Schlitten 16 und an der Halteplatte 14 befestigte Kolben-Zylinder- Einheit 17 ermöglicht es, die Halteplatte 14 mit den daran befestigten Elementen aus ihrer Arbeitsposition in eine inaktive Position oberhalb des Stapels 3 anzuheben. Die gemeinsame Aufhängung der Ausstoßrolle 10, des Trennblechs 12 und der Trennschuhe 11 an der Halteplatte 14 hat den Vorteil, daß diese Elemente von einem einzigen gemeinsamen Verfahrantrieb querverstellt, sowie von einem einzigen gemeinsamen Hebeantrieb (Kolben-Zylinder-Einheit 17) angehoben und abgesenkt werden können.Guide rods 15 is attached. At their upper end, the guide rods 15 are fastened to a slide 16, which is mounted so as to be displaceable on a crossbar. A piston-cylinder unit 17 also fastened to the slide 16 and to the holding plate 14 makes it possible to lift the holding plate 14 with the elements attached to it from its working position into an inactive position above the stack 3. The common suspension of the ejection roller 10, the separating plate 12 and the separating shoes 11 on the holding plate 14 has the advantage that these elements are transversely adjusted by a single common traversing drive, and raised and lowered by a single common lifting drive (piston-cylinder unit 17) can.
An der Halteplatte 14 ist eine zweite Halteplatte 18 befestigt, die in Figur 2 vorne und in Figur 3 links von der Halteplatte 14 angeordnet ist. Die zweite Halteplatte 18 ist ausschließlich über dämpfend wirkende Gummielemente 19 an der Halteplatte 14 befestigt, so daß die beiden Halteplatten 14, 18 voneinander schwingungsentkoppelt sind. Als Gummielemente 19 werden bevorzugt sogenannte Metallgummi-Elemente eingesetzt, die gummielastisch sind und dämpfend wirken. An der zweiten Halteplatte 18 sind das Trennblech 12 und der Vibrator 13 starr aufgehängt befestigt. Die schwingungs-entkoppelte Befestigung der zweiten Halteplatte 18 an der als Halter dienenden ersten Halteplatte 14 bewirkt, daß der Vibrator 13 die erste Halteplatte 14 nicht in Schwingung versetzen kann. An dieser nicht schwingenden Halteplatte 14 sind die Ausstoßrollen 10 über einen Lagerarm 20 befestigt. Der Trennschuh 11 ist an der schwingenden Halteplatte 18 befestigt, so daß er gemeinsam mit dem Trennblech 12 in Schwingung versetzt wird. Die Schwingung des Trennschuh 11 führt dazu, daß die Bögen 1 besser nach unten auf den Stapel 3 abgleiten. A second holding plate 18 is fastened to the holding plate 14, which is arranged at the front in FIG. 2 and to the left of the holding plate 14 in FIG. 3. The second holding plate 18 is attached to the holding plate 14 exclusively via damping rubber elements 19, so that the two holding plates 14, 18 are vibration-decoupled from one another. So-called metal rubber elements, which are rubber-elastic and have a damping effect, are preferably used as rubber elements 19. The partition plate 12 and the vibrator 13 are rigidly attached to the second holding plate 18. The vibration-decoupled fastening of the second holding plate 18 to the first holding plate 14 serving as a holder means that the vibrator 13 cannot cause the first holding plate 14 to vibrate. The ejection rollers 10 are fastened to this non-oscillating holding plate 14 via a bearing arm 20. The separating shoe 11 is fastened to the oscillating holding plate 18, so that it is set in vibration together with the separating plate 12. The vibration of the separating shoe 11 leads to the sheets 1 sliding better down onto the stack 3.
