Description

Die Erfindung betrifft die Verpackungsbranche und dort eine Vorrichtung zum Überführen flachliegender Gegenstände, insbesondere zusammengelegter Faltschachteln, von einer Abgabestation zu einer Aufnahmestation, mit wenigstens einem entlang einer Bahn um die Drehachse schwenkbaren Saugkopf, welcher mindestens einen Sauger aufweist, wobei dem Saugkopf ein Antrieb zugeordnet ist, um den Saugkopf um die Drehachse zu bewegen, der Saugkopf an einem Ausleger radial beweglich angeordnet ist, ein Linearantrieb dem radialen Auslenken des Saugkopfes dient, und der Linearantrieb in radialer Richtung zur Drehachse ausgerichtet ist.The invention relates to the packaging industry and there is a device for Transfer of flat objects, in particular collapsed Folding cartons, from a delivery station to a receiving station, with at least a suction head pivotable along a path about the axis of rotation, which has at least one sucker, the suction head is associated with a drive, to move the suction head about the axis of rotation, the suction head on a boom is arranged radially movable, a linear drive the radial deflection of the Suction head is used, and the linear drive in the radial direction to the axis of rotation is aligned.

Eine derartige Vorrichtung ist aus der DE 198 45 384 A1 bekannt. Die bekannte Vorrichtung dient dazu, zusammengelegte Faltschachteln, die in einem Magazin bevorratet sind, mittels eines Saugkopfes einzeln dem Magazin zu entnehmen und einer Aufnahmestation zuzuführen. Dabei kann der Saugkopf sowohl um die Drehachse geschwenkt als auch in linearer Weise radial zur Drehachse verfahren werden, um die notwendige Bahn zu beschreiben, die jeweils eine Faltschachtel zwischen zwei Mitnehmern einer Förderkette bringt.Such a device is known from DE 198 45 384 A1. The well-known Device serves to fold cartons, which are in a magazine are stored, by means of a suction head individually to remove the magazine and to feed a receiving station. In this case, the suction head both to the Swiveled axis and moved in a linear manner radially to the axis of rotation be to describe the necessary lane, each a folding box brings between two carriers of a conveyor chain.

Die bekannte Vorrichtung hat den Nachteil, dass sie ein relativ großes Massenträgheitsmoment aufweist, da sich ihr Linearantrieb in einem bestimmten radialen Abstand von einem relativ großen Minimalabstand bis hin zu einem noch größeren Maximalabstand relativ zur Drehachse erstreckt.The known device has the disadvantage that it is a relatively large Mass moment of inertia, since their linear drive in a certain Radial distance from a relatively large minimum distance to a still greater maximum distance relative to the axis of rotation extends.

Es ist Aufgabe der Erfindung diesen Nachteil zu beseitigen, um die Vorrichtung schneller betreiben zu können. Zudem soll sie sehr genau und sehr zuverlässig arbeiten.It is an object of the invention to overcome this drawback to the device to operate faster. In addition, it should be very accurate and very reliable work.

Gelöst ist die Aufgabe gemäß dem kennzeichnenden Teil des Anspruchs 1. Danach liegt der Linearantrieb derart auf der Drehachse, ein Ende des Linearantriebes ist am Saugkopf und das andere Ende des Linearantriebes um 180 Grad um die Drehachse versetzt angeordnet und der Linearantrieb ist um die Drehachse schwenkbar bzw. rotierbar. The problem is solved according to the characterizing part of claim 1. Thereafter the linear drive is so on the axis of rotation, one end of the linear drive is on Suction head and the other end of the linear drive 180 degrees around the axis of rotation arranged offset and the linear drive is pivotable about the axis of rotation or rotatable.

Die erfindungsgemäße Vorrichtung hat den Vorteil, dass ihr Massenträgheitsmoment vergleichsweise niedrig ist, da der Linearantrieb propellorartig um die Drehachse rotiert. Aufgrund seiner geringen Masse ist er auch bei sehr schnellem Betrieb sehr ortsgenau und zeitgenau. Die Faltschachteln können insofern sicher an der Abgabestation ergriffen, weitertransportiert und schließlich an einer bestimmten Stelle der Aufnahmestation abgelegt werden. Zudem ist die Vorgeschlagene Vorrichtung kostengünstig und infolge ihres relativ einfachen Aufbaus auch sehr zuverlässig.The device according to the invention has the advantage that its mass moment of inertia is relatively low, since the linear drive rotates propeller-like manner about the axis of rotation. Due to its low mass, it is very accurate even during very fast operation and timely. The cartons can safely so far at the delivery station seized, transported on and finally at a certain point of the receiving station be filed. In addition, the proposed device is inexpensive and due to their relatively simple structure also very reliable.

Vorteilhafte Ausgestaltungen der vorgeschlagenen Vorrichtung sind in den Ansprüchen 2 bis 10 beschrieben.Advantageous embodiments of the proposed device are in the claims 2 to 10 described.

Weist gemäß Anspruch 2 der Linearantrieb ein antreibendes Teil und ein vom antreibenden Teil angetriebenes, bewegliches Teil auf, wobei das antreibende Teil quer und insbesondere mittig von der Drehachse passiert wird, und der Saugkopf am beweglichen Teil vorgesehen ist, so sind damit mehrere Vorteile erreicht. Zum einen ist ein nahe an der Drehachse angeordnetes oder mittig diese passierende, antreibendes Teil sehr schnell betreibbar. Zum anderen ist die Masse des Linearantriebes gleichmäßig verteilt, wenn das antreibende Teil auf gegenüberliegenden Seiten der Drehachse jeweils zum Teil, idealerweise zur Hälfte angeordnet ist.Has according to claim 2, the linear drive a driving part and a from driving part driven, moving part, wherein the driving part transversely and in particular centrally of the axis of rotation is passed, and the suction head on is provided movable part, so that several advantages are achieved. For one thing is a arranged close to the axis of rotation or centrally this passing, driving Part very fast operable. On the other hand, the mass of the linear drive evenly distributed, with the driving part on opposite sides of the Each axis of rotation in part, ideally arranged in half.

Als sehr schnell und sehr ortsgenau zu betreibender Antrieb eignet sich ein sogenannter Linearmotor (Anspruch 3). Das ist ein elektromagnetischer Linearantrieb, der ein antreibendes Teil und ein angetriebenes, mit dem Saugkopf verbundenes Teil aufweist.As very fast and very accurate to drive to operate is suitable so-called linear motor (claim 3). This is an electromagnetic linear actuator, the one driving part and a driven, connected to the suction head part having.

Eine deutliche Steigerung der Anzahl der entnommenen Gegenstände pro Zeitintervall wird erreicht, wenn der Linearantrieb rotierend betreiben wird und zwei nacheinander arbeitende Saugköpfe am Linearantrieb vorgesehen sind. Hierfür kann an gegenüberliegenden Enden des angetriebenen Teils (Anspruch 4) jeweils ein Saugkopf mit Sauger vorgesehen werden, so dass nach jeweils einer halben Umdrehung ein Saugkopf einen Gegenstand entnehmen kann. Eine noch höhere Leistung wird erreicht, wenn zwei Linearantriebe mit jeweils zwei gegenüberliegenden Saugköpfen vorgesehen sind, die um einen Winkel, insbesondere einen rechten Winkel versetzt sind (Anspruch 5). A significant increase in the number of objects removed per time interval is reached when the linear actuator is rotating and two consecutively working suction heads are provided on the linear drive. For this purpose can opposite ends of the driven part (claim 4) each one Suction head be provided with suction, so after every half a Turn a suction head can remove an object. An even higher one Performance is achieved when two linear drives each with two opposite Suction heads are provided which by an angle, in particular a right Angle are offset (claim 5).

Dann stehen vier um jeweils 90 Grad zueinander versetzte Saugköpfe zur Verfügung, die nach jeweils einer viertel Umdrehung nacheinander an das Magazin gelangen.Then there are four suction heads offset by 90 degrees, which arrive at the magazine one after the other every quarter turn.

Ist der Linearantrieb kraftgesteuert (Anspruch 6), so hat dies den Vorteil, dass auch bei einem Festklemmen eines Stapels flachliegender Gegenstände jeweils ein Gegenstand vom dem Sauger entnommen werden kann. Beim Festklemmen eines Stapels wird zunächst der vordere Gegenstand entnommen. Der nachfolgende Gegenstand rückt nicht in die vordere Position, sondern verbleibt bei einem Stau etwas von der vorderen Position entfernt im Magazin. Die Kraftsteuerung sorgt dafür, dass der Sauger gegen den nachfolgenden Gegenstand gedrückt wird. Dabei wird zwangsläufig der Saugkopf um eine Gegenstandsdicke weiter in das Magazin hinein bewegt. Erst wenn eine bestimmte, vorgegebene Kraft, mit welcher der Saugkopf gegen den aufzunehmenden Gegenstand drückt, erreicht ist, wird die Bewegungsrichtung des Saugkopfes umgekehrt, so dass der Gegenstand aus dem Magazin entnommen werden kann. Solange das Festklemmen nicht beseitigt ist, greift der Saugkopf immer tiefer in das Magazin ein, um die Gegenstände aufzunehmen. Das Festsitzen wird dabei im Regelfall allein durch das Drücken des Saugkopfes auf den Stapel und die teilweise Entleerung des Magazins behoben, wobei sich der Stapel, z. B. durch Federkraft oder Schwerkraft und ohne Zutun einer Bedienungsperson wieder in Richtung der vorderen Position bewegt. Der sodann in die vorderste Position gelangte Gegenstand wird vom Saugkopf nach einer verkürzten Bewegungstrecke des Saugkopfes aufgrund der dann schon erreichten Kraft entnommen.If the linear drive is force-controlled (claim 6), this has the advantage that even at clamping a stack of flat objects one at a time Subject from the sucker can be removed. When clamping a Stack is first taken from the front object. The following Item does not move to the front position, but remains in a traffic jam away from the front position in the magazine. The force control ensures that the nipple is pressed against the subsequent object. It will inevitably the suction head by an article thickness further into the magazine emotional. Only when a certain predetermined force with which the suction head is pressed against the object to be recorded, is reached, the Direction of movement of the suction head vice versa, so that the object from the Magazine can be removed. As long as the clamping is not eliminated, attacks the suction head deeper into the magazine to take the objects. Sticking is usually only by pressing the suction head on fixed the stack and the partial emptying of the magazine, whereby the stack, z. B. by spring force or gravity and without the intervention of an operator moved back towards the front position. The then in the foremost position The object is moved from the suction head after a shortened movement of the Suction head due to the then already reached force removed.

Die Kraftmessung kann mittels einer Kraftmesseinrichtung, einer Druckmessung oder durch Messung einer anderen, mit der Kraft in einem funktionellen Zusammenhang stehenden Größe, z. B. der Leistungsaufnahme des Linearantriebs, erfolgen. Die Messung der Leistungsaufnahme eines Linearantriebs und seine ortsgenaue Regelung ist für ein ortsgenaues und kraftgenaues Ansetzen des Saugers am zu entnehmenden Gegenstand von Vorteil. Als Antrieb eignet sich hierfür ein Servomotor genauso wie ein Linearmotor. Diese Linearantriebe können auch wahlweise positionsgesteuert (ortsgenaue Saugkopfposition) oder kraftgesteuert werden.The force measurement can by means of a force measuring device, a pressure measurement or by measuring another, with the force in a functional context standing size, z. B. the power consumption of the linear drive, done. The Measurement of the power consumption of a linear drive and its location-specific control is for a precise and precise placement of the teat on to be removed Subject of advantage. For this purpose, a servomotor is just as suitable as a drive Linear motor. These linear drives can also optionally position-controlled (location accurate suction head position) or force controlled.

Ist an der Abgabestation ein Magazin, und um einen Winkel dazu versetzt, ein Schwenkbereich der Vorrichtung, ein Ersatzmagazin für zusammengelegte Faltschachteln vorgesehen (Anspruch 7), so kann wahlweise das eine oder das andere Magazin entleert werden. Is at the delivery station a magazine, and offset by an angle, a Swivel range of the device, a replacement magazine for collapsed Folding boxes provided (claim 7), so either one or the other Magazine be emptied.

Ein wesentlicher Vorteil des vorgestellten Gegenstandes ist, dass der Ausleger, an dem der Saugkopf vorgesehen ist, vom Linearantrieb oder einem antreibenden Teil gebildet werden kann (Anspruch 8). Dadurch wird ein beim Stand der Technik benötigter, separater Ausleger gespart, was die Vorrichtung deutlich vereinfacht und kostengünstiger macht. In besonderer Weise eignet sich hierfür ein antreibendes Teil eines Linearmotors.A major advantage of the presented object is that the boom, to the suction head is provided by the linear drive or a driving part can be formed (claim 8). This is one in the prior art required, separate boom saved, which significantly simplifies the device and makes it cheaper. In a special way, this is a driving part a linear motor.

Prinzipiell kann die Vorrichtung hin- und herschwenkend oder kontinuierlich umlaufend (Anspruch 9, Anspruch 10) betrieben werden.In principle, the device can swing back and forth or continuously circulating (Claim 9, claim 10) are operated.

Through the hollow shaft 21 is a via a rotary feedthrough 23rd introduced vacuum further into a guided by the driven part 15 line 24 and thus brought to the suction 7. The power supply is via one Slip ring 25. The hollow shaft 21 is of the attached to a holder 26 drive. 9 via two toothed belt wheels 27, 28 and a toothed belt 29 driven.

Der Linearantrieb 11 weist eine Kraftsteuerung 30 auf, mittels der nach einem Aufbau einer bestimmten, gegen eine Faltschachtel 2 wirkenden Antriebskraft ein Anliegen der Sauger 7 an der Faltschachtel 2 am Faltschachtelmagazin 3 erkannt wird. Erst danach wird das angetriebene Teil 15 Richtung Drehachse 8 relativ zum antreibenden teil 14 verschoben (Figur 3), um die Faltschachtel 2 aus dem Faltschachtelmagazin 3 zu entnehmen. Während des Umlaufs wird das angetriebene Teil 15 stets hin und her verschoben, je nachdem welcher Drehwinkel gerade eingenommen ist, damit die beiden Saugköpfe 6 jeweils eine Faltschachtel 2 entnehmen und wieder abgeben. Entsprechend wird die Vakuumversorgung für die Sauger 7 betrieben.The linear drive 11 has a force control 30, by means of a structure a certain, acting against a carton 2 driving force is a concern of the Sucker 7 is recognized on the carton 2 on the folding carton magazine 3. Only after the driven part 15 is in the direction of the axis of rotation 8 relative to the driving part 14 shifted (Figure 3) to the carton 2 from the folding box magazine 3 to remove. During the circulation, the driven part 15 is always back and forth shifted, depending on which angle of rotation is just taken, so that the two suction cups 6 each remove a folding box 2 and release again. Accordingly, the vacuum supply for the suction 7 is operated.

Beim Ausführungsbeispiel der Figur 4 sind zwei Linearantriebe 11 mit Saugköpfen 6 vorgesehen, die um einen rechten Winkel zueinander versetzt sind. Diese Vorrichtung 1 wird in analoger Weise zum vorherigen Ausführungsbeispiel betrieben. Die Anzahl der abgezogenen Faltschachteln 2 ist hier jedoch vier Faltschachteln pro Umlauf.
