Definitions
- the invention relates to a device according to the preamble of claim 1.
- EP A1 0 332 828 describes a device for separating stacked sheets of paper, which, however, is designed as a rotary feeder, the satellites of which are arranged in a rotor and rotate about their own axis during the rotation of the rotor. They have drum disks spaced from one another, between which the suction heads are arranged.
- the rotor is located under a feeder magazine for receiving the stack, with the drum disks of the satellites rolling on the underside of the stack so that the bottom sheet, the fold of which the suction heads grasp and temporarily hold, is wound around the drum disks.
- the sheet is first drawn into a conveyor gap, which is formed in each satellite between the middle drum disc and an endless conveyor belt partially wrapping around it, and then pushed on a path tangentially away from the drum discs beyond the circumferential circle of the rotor.
- a removal conveyor with rotating grippers is assigned to the rotary feeder, each of which is to take over the paper sheet ejected by the satellites, but this is only possible if the fold is pushed as directly as possible from the conveyor gap into the gripper.
- a roller feeder also arranged below a stack magazine is also described in DE-OS 27 32 591, in which a single suction head is arranged at one end of an angle lever, the other end is guided in a linear guide and the pivot bearing is eccentrically connected to a rotating planet gear is arranged, which in turn is in engagement with a fixed internal ring gear. This results in an angular orbit with several reversal points for the suction head, one of which lies in the takeover area.
- the present invention takes a completely different approach with respect to both known feeders, in that it is based on the task of arranging and driving the suction heads outside of a rotor in such a way that they can be separated from the neighboring product quickly and safely without any significant deformation of even a free-standing outermost product cope and can transfer to the removal device itself.
- the object of the invention in connection with a removal device with controlled grippers rotating in succession at regular intervals, is to guide the suction heads arranged outside the rotor with respect to the orbit of the grippers in such a way that they insert the edge of the products they grip into the grippers .
- the rotor designated overall by 10
- the rotor 10 is rotatably mounted in a housing 13 by means of a roller bearing 12 and in the circumferential direction 88 via a toothed ring 14 fastened to it, which meshes with a toothed belt 16 driven in rotation.
- the rotor 10 carries three suction heads 18 distributed in the circumferential direction, each of which is anchored to the rotor disk 24 via a swivel arm 20 and a swivel axis 22.
- the control link 38 is located on the end face 40 of the insert 42, which is removably fastened in the housing 13, facing the rotor disk 24, its track 36 being deeper than the other track 34, with the following rollers 32 and 30 being correspondingly offset with respect to one another in the axial direction .
- tracks 34 and 36 remain closed, even if they overlap. Both tracks can therefore run in their diametrically opposite sections close to the rotor center; with a small radial space requirement, this results in a precise and vibration-free swivel drive 44 for the suction heads 18.
- the track 34 has a bulge 46, which reaches the arm of each control lever 28, which cooperates with this track 34 and carries the follower roller 30, in overrun mode and leaves in drag mode, since the follower roller 30 in question rotates in the direction of rotation rising edge 47 of the bulge 46 is pushed inwards.
- the arrangement of the rotor 10 with respect to the stack - here above the standing stack 48 - is such that the bulge 46 faces the stack 48 and the relevant follow-up roller 30 in the region of the bulge 46 most approaches the stack 48. This also applies, as can be seen in FIG.
- a removal device As can also be seen in FIG. 8, above the stack 48 there is the guide channel 54 of a removal device, generally designated 56, which is provided with controlled grippers 58 rotating in succession at regular intervals, which grips in a known manner on a channel 54 rotating in the conveying direction F , endless traction element (not visible) are anchored.
- the rotor 10 is laterally offset with respect to the channel 54, so that the suction heads 18, which swivel up on their swivel arms 20 and at the same time are driven by their rotating axes 22, hold the gripped product edge longer and, within a longer run-in area, directly into the open mouth facing downwards Can insert gripper 58.
- the grippers 58 When the time comes, the grippers 58 are closed and the suction heads 18 are ventilated.
- the rotor 10 specifically the rotor disk 24 is designed as a rotary slide valve which interacts with a valve body 60 engaging in a central opening of the rotor disk 24.
- the valve body 60 has control slots 62 and 64 which communicate with a vacuum source (not shown) or with the atmosphere.
- the connection 65 to a suction line 66 runs through the area of the insert 42 enclosed by the control link 38.
- Radial connecting channels 68 are provided in the rotor disk 24, which in the course of one revolution of the rotor disk 24 first with the vacuum slot 62 and then with the ventilation slot 64 in Connect (similar to what is also described in the aforementioned DE-OS).
- the radial connecting channels 68 of the rotor disk 24 are permanently connected to the suction heads 18 by connecting channels 70 formed through the axes 22.
- the course of the control link 38 and the distance between the suction heads 18, as can be seen in FIG. 8 in conjunction with FIG. 3, is selected such that, on the one hand, the suction heads 18 bypass the transfer point 72 and, on the other hand, there are suction heads both in the transfer area and in the transfer area 18 are located. This allows a very fast working method, especially since there is still a lot of time available both for the transfer and for the transfer and all movements take place fluently.
- the resilient mounting of the suction heads is helpful.
- the suction heads 18 are attached to hollow pins 74, which are displaceably guided in heads 76 attached to the ends of the axes 22 are, but under the action of a hairpin spring 78 assume a rest position determined by a stop shoulder 80, with the hollow pin 74 communicating with the axial channels 70 of the axes 22 in each displacement position.
- the suction heads 18 are guided by means of hollow swivel arms 82, which in turn are anchored to the axes 22.
- a compression spring 84 holds the suction heads 18 in the stop position shown. Further details of both variants are readily apparent from the drawing.
- the stack support is preceded - as indicated only in FIG. 8 - by a periodically or continuously driven feed device 86 which e.g. can be designed in the form of a conveyor belt.

Description
Die Erfindung betrifft eine Einrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
In der EP A1 0 332 828 ist eine Vorrichtung zum Vereinzeln gestapelter Papierbogen beschrieben, die allerdings als Rotationsanleger ausgebildet ist, dessen in einem Rotor angeordnete Satelliten während des Umlaufs des Rotors um ihre eigene Achse rotieren. Sie besitzen voneinander in Abständen angeordnete Trommelscheiben, zwischen denen die Saugköpfe angeordnet sind. Der Rotor befindet sich unter einem Anlegermagazin für die Aufnahme des Stapels, wobei die Trommelscheiben der Satelliten sich auf der Stapelunterseite abwälzen, so dass der unterste Bogen, dessen Falz die Saugköpfe ergreifen und vorübergehend festhalten, um die Trommelscheiben gewickelt wird. Dabei wird der Bogen zuerst in einen Förderspalt eingezogen, der bei jedem Satelliten zwischen der mittleren Trommelscheibe und einem diese teilweise umschlingenden endlosen Förderband gebildet ist und alsdann auf einer tangential von den Trommelscheiben wegführenden Bahn über den Umfangskreis des Rotors hinausgeschoben. Dem Rotationsanleger ist ein Abtransportförderer mit umlaufenden Greifern zugeordnet, die jeweils den von den Satelliten ausgestossenen Papierbogen übernehmen sollen, was allerdings nur dann gelingt, wenn der Falz aus dem Förderspalt möglichst direkt in den Greifer eingeschoben wird. Dies führt dazu, dass der Bogen auch nach Ergreifen des Falzes noch lange nach aussen geschoben, d.h. regelrecht gestaucht wird und er sich entsprechend auswölben muss, wobei umgekehrt diese Deformation sich schlagartig zurückbildet, wenn die nachlaufende Kante den Förderspalt verlässt: Bei dicken Bogen sind die Grenzen bald erreicht.EP A1 0 332 828 describes a device for separating stacked sheets of paper, which, however, is designed as a rotary feeder, the satellites of which are arranged in a rotor and rotate about their own axis during the rotation of the rotor. They have drum disks spaced from one another, between which the suction heads are arranged. The rotor is located under a feeder magazine for receiving the stack, with the drum disks of the satellites rolling on the underside of the stack so that the bottom sheet, the fold of which the suction heads grasp and temporarily hold, is wound around the drum disks. The sheet is first drawn into a conveyor gap, which is formed in each satellite between the middle drum disc and an endless conveyor belt partially wrapping around it, and then pushed on a path tangentially away from the drum discs beyond the circumferential circle of the rotor. A removal conveyor with rotating grippers is assigned to the rotary feeder, each of which is to take over the paper sheet ejected by the satellites, but this is only possible if the fold is pushed as directly as possible from the conveyor gap into the gripper. This means that even after the fold has been gripped, the sheet is pushed outward for a long time, that is to say it is actually compressed, and it turns accordingly bulge, which conversely, this deformation suddenly disappears when the trailing edge leaves the conveyor gap: With thick sheets, the limits will soon be reached.
Ein ebenfalls unterhalb eines Stapelmagazins angeordneter Rollenanleger ist ferner in der DE-OS 27 32 591 beschrieben, bei dem ein einziger Saugkopf an dem einen Ende eines Winkelhebels angeordnet ist, dessen anderes Ende in einer linearen Führung geführt und dessen Schwenklager exzentrisch an einem umlaufend angetriebenen Planetenrad angeordnet ist, das seinerseits mit einem feststehenden Innenzahnkranz in Eingriff steht. Daraus ergibt sich für den Saugkopf eine eckige Umlaufbahn mit mehreren Umkehrpunkten, von denen der eine im Ubernahmebereich liegt.A roller feeder also arranged below a stack magazine is also described in DE-OS 27 32 591, in which a single suction head is arranged at one end of an angle lever, the other end is guided in a linear guide and the pivot bearing is eccentrically connected to a rotating planet gear is arranged, which in turn is in engagement with a fixed internal ring gear. This results in an angular orbit with several reversal points for the suction head, one of which lies in the takeover area.
Die vorliegende Erfindung geht in bezug auf beide bekannte Anleger einen völlig anderen Weg, indem ihr die Aufgabe zugrunde liegt, die Saugköpfe so ausserhalb eines Rotors anzuordnen und anzutreiben, dass sie ohne nennenswerte Deformation auch eines freistehenden äussersten Produktes das Separieren vom benachbarten Produkt schnell und sicher bewältigen und die Ubergabe an die Abtransportvorrichtung selbst vollziehen können.The present invention takes a completely different approach with respect to both known feeders, in that it is based on the task of arranging and driving the suction heads outside of a rotor in such a way that they can be separated from the neighboring product quickly and safely without any significant deformation of even a free-standing outermost product cope and can transfer to the removal device itself.
Die Lösung dieser Aufgabe gemäss den kennzeichnenden Merkmalen des Anspruches 1 ist frei von räumlichen Beengungen; sie ermöglicht auch den schnellen und trotzdem schonenden Abbau eines Stapels von beliebig dünnen oder dicken Produkten, wobei der Stapel weitgehend beliebig ausgerichtet sein kann.The solution to this problem according to the characterizing features of claim 1 is free of spatial restrictions; it also enables a stack to be dismantled quickly and yet gently from any thin or thick products, the stack being able to be oriented as desired to a large extent.
Des weiteren liegt der Erfindung in Verbindung mit einer Abtransportvorrichtung mit in regelmässigen Abständen aufeinanderfolgend umlaufenden gesteuerten Greifern die Aufgabe zugrunde, die ausserhalb des Rotors angeordneten Saugköpfe bezüglich der Umlaufbahn der Greifer so zu führen, dass sie den von ihnen ergriffenen Rand der Produkte in die Greifer einlegen.Furthermore, the object of the invention, in connection with a removal device with controlled grippers rotating in succession at regular intervals, is to guide the suction heads arranged outside the rotor with respect to the orbit of the grippers in such a way that they insert the edge of the products they grip into the grippers .

Gemäss Fig. 1 ist der gesamthaft mit 10 bezeichnete Rotor mittels eines Wälzlagers 12 in einem Gehäuse 13 drehbar gelagert und über einen an ihm befestigten Zahnkranz 14, der mit einem Zahnriemen 16 kämmt, in Umlaufrichtung 88 rotierend angetrieben. Der Rotor 10 trägt im Umfangssinne verteilt drei Saugköpfe 18, die je über einen Schwenkarm 20 und einer Schwenkachse 22 an der Rotorscheibe 24 verankert sind. Die Achsen 22, die in der Rotorscheibe 24 mittels Wälzlager 26 gelagert sind, tragen an ihrem aus der Rotorscheibe 24 heraustretenden hinteren Ende einen zweiarmigen Steuerhebel 28 mit an den Hebelenden angeordneten Folgerollen 30 bzw. 32, die jeweils in die eine bzw. andere Spur 34 bzw. 36 einer in sich geschlossenen, gesamthaft mit 38 bezeichneten Steuerkulisse eingreifen. Die Steuerkulisse 38 befindet sich an der der Rotorscheibe 24 zugewandten Stirnseite 40 eines in dem Gehäuse 13 wegnehmbar befestigten Einsatzes 42, ihre Spur 36 ist dabei tiefer als die andere Spur 34, wobei die Folgerollen 32 bzw. 30 in bezug aufeinander in Achsrichtung entsprechend versetzt sind. Hierbei bleiben die Spuren 34 bzw. 36 je in sich geschlossen, auch wenn sie sich überschneiden. Beide Spuren können also in ihren einander diametral gegenüberliegenden Abschnitten nahe zum Rotorzentrum verlaufen; bei geringem radialen Platzbedarf ergibt sich dadurch ein präziser und erschütterungsfreier Schwenkantrieb 44 für die Saugköpfe 18.1, the rotor, designated overall by 10, is rotatably mounted in a
Die Spur 34 weist, wie Fig.3 erkennen lässt, eine Ausbuchtung 46 auf, die den mit dieser Spur 34 zusammenwirkenden, die Folgerolle 30 tragenden Arm jedes Steuerhebels 28 in Schubbetrieb erreicht und in Schleppbetrieb verlässt, da die betreffende Folgerolle 30 durch die in Umlaufrichtung ansteigende Flanke 47 der Ausbuchtung 46 nach innen gedrängt wird. Die Anordnung des Rotors 10 in bezug auf den Stapel - hier oberhalb des stehenden Stapels 48 - ist so getroffen, dass die Ausbuchtung 46 zum Stapel 48 hin weist und die betreffende Folgerolle 30 im Bereiche der Ausbuchtung 46 sich dem Stapel 48 am meisten annähert. Dies gilt, wie Fig. 8 erkennen lässt, auch für die Saugköpfe 18, da ihre Schwenkarme 20 sich von ihren Achsen 22 im wesentlichen gleichsinnig zu dem mit der Spur 34 zusammenwirkenden Arm der Steuerhebel 28 erstrecken, so dass die Ausbuchtung die Ubernahmestelle 50 bestimmt und diese die Schwenkarme 20 mit ihren Saugköpfen 18 geschoben erreichen und gezogen verlassen. Die Umlaufbahn 90 der Saugköpfe 18 besitzt also einen Umkehrpunkt und dies hat zur Folge, dass die Saugköpfe 18 während des Wechsels reichlich Zeit haben, sich an dem Rand des äussersten Produktes 49 (Fig.6) anzusaugen und, da sie wie Fig.8 erkennen lässt, den Stapel 48 kippend verlassen, den Produkterand von dem benachbarten Produkt 52 sauber zu trennen (Fig.8). In diesem Zusammenhang ist es von Vorteil, wenn die Saugköpfe 18 federnd zurückdrängbar gehaltert sind, wie dies anhand der Fig. 4-7 noch näher zu erläutern sein wird, da dadurch die Ubernahmestelle 50 eine dritte Dimension erhält.The
Wie Fig. 8 ferner erkennen lässt, befindet sich oberhalb des Stapels 48 der Führungskanal 54 einer gesamthaft mit 56 bezeichneten Abtransportvorrichtung, die mit in regelmässigen Abständen aufeinanderfolgend umlaufenden gesteuerten Greifern 58 versehen ist, die in bekannter Weise an einem im Kanal 54 in Förderrichtung F umlaufenden, endlosen Zugorgan (nicht sichtbar) verankert sind. Der Rotor 10 ist in bezug auf den Kanal 54 seitlich versetzt, so dass die an ihren Schwenkarmen 20 hochschwenkenden und zugleich durch ihre umlaufenden Achsen 22 angetriebenen Saugköpfe 18 den ergriffenen Produkterand länger halten und innerhalb eines längeren Einfahrbereiches direkt in das nach unten gekehrte Maul der geöffneten Greifer 58 einlegen können. Ist es soweit, werden die Greifer 58 geschlossen und die Saugköpfe 18 belüftet.As can also be seen in FIG. 8, above the
Hierfür ist, wie insbesondere Fig.1 und 2 zeigen, der Rotor 10, namentlich die Rotorscheibe 24 als Drehschieber ausgebildet, der mit einem in eine zentrale Öffnung der Rotorscheibe 24 eingreifenden Ventilkörper 60 zusammenwirkt. Der Ventilkörper 60 weist Steuerschlitze 62 bzw. 64 auf, die mit einer nicht dargestellten Unterdruckquelle bzw. mit der Atmosphäre kommunizieren. Die Verbindung 65 zu einer Saugleitung 66 verläuft durch den von der Steuerkulisse 38 umschlossenen Bereich des Einsatzes 42. In der Rotorscheibe 24 sind radiale Verbindungskanäle 68 vorgesehen, die im Verlauf einer Umdrehung der Rotorscheibe 24 zuerst mit dem Unterdruckschlitz 62 und alsdann mit dem Belüftungsschlitz 64 in Verbindung kommen (ähnlich wie dies in der eingangs genannten DE-OS auch beschrieben ist). Die radialen Verbindungskanäle 68 der Rotorscheibe 24 sind dauernd mit durch die Achsen 22 hindurch ausgebildeten Verbindungskanälen 70 zu den Saugköpfen 18 verbunden.For this purpose, as shown in particular in FIGS. 1 and 2, the
Der Verlauf der Steuerkulisse 38 und der Abstand zwischen den Saugköpfen 18 ist, wie Fig.8 in Verbindung mit Fig.3 erkennen lässt, so gewählt, dass einerseits die Saugköpfe 18 die Ubergabestelle 72 umfahren und andererseits sowohl im Ubergabebereich als auch im Ubernahmebereich sich Saugköpfe 18 befinden. Dies lässt eine sehr schnelle Arbeitsweise zu, zumal dennoch sowohl für die Ubernahme als auch für die Ubergabe sehr viel Zeit zur Verfügung steht und alle Bewegungen fliessend erfolgen.The course of the
Wie bereits erwähnt, ist hierbei die federnde Halterung der Saugköpfe hilfreich. Gemäss Fig.4 und 5 sind die Saugköpfe 18 an Hohlzapfen 74 angebracht, die in an den Enden der Achsen 22 angebrachten Köpfen 76 verschiebbar geführt sind, die aber unter der Wirkung einer Haarnadelfeder 78 eine durch eine Anschlagschulter 80 bestimmte Ruhelage einnehmen, wobei in jeder Verschiebelage der Hohlzapfen 74 diese mit den axialen Kanälen 70 der Achsen 22 kommunizieren. Gemäss Fig.6 und 7 sind die Saugköpfe 18 mittels hohler Schwenkarme 82 geführt, die ihrerseits an den Achsen 22 verankert sind. Eine Druckfeder 84 hält die Saugköpfe 18 in der dargestellten Anschlaglage. Weitere Einzelheiten beider Varianten sind ohne weiteres anhand der Zeichnung erkennbar. Hingegen soll ausdrücklich darauf hingewiesen werden, dass in jedem Fall die Führungen (hier durch 74 bzw. 82) der Saugköpfe 18 in deren Ubernahmestellung in Richtung des Umlaufs geneigt sind, um einen längeren Kontakt der Saugköpfe 18 mit dem Stapel 48 zu ermöglichen.As already mentioned, the resilient mounting of the suction heads is helpful. 4 and 5, the
Da das Vereinzeln bei sehr hoher Geschwindigkeit des Rotors 10 bzw. der Abtransportvorrichtung 56 vor sich gehen kann, ist - wie in Fig.8 lediglich angedeutet - der Stapelauflage eine periodisch oder kontinuierlich angetriebene Zuführvorrichtung 86 vorgeschaltet, die z.B. in Form eines Förderbandes ausgebildet sein kann.Since the separation can take place at a very high speed of the
