Abstract

The invention is a method and a device for blocking a stack of stacked objects. A device for blocking in accordance with the invention includes two opposed side walls which engage the stack, a pressing device which has at least two pressing elements opposite one another which contact the stack, between which elements of the stack are compressed while contacting the side walls, and charging electrodes which charge the stack, and wherein the charging electrodes are located in at least one of the pressing elements.

Description

Die Erfindung betrifft eine Vorrichtung zum Verblocken eines Stapels von gestapelten Gegenständen, wie z.B. gestapelten Zeitungen, Zeitschriften oder dergleichen, gemäß dem Oberbegriff des Hauptanspruchs.The invention relates to a device for blocking a stack of stacked items such as stacked newspapers, magazines or the like, according to the preamble of the main claim.

Eine derartige Vorrichtung ist bekannt (WO-96/33118) und weist einen Hubtisch auf, mit welchem ein darauf aufliegender Stapel von gestapelten Gegenständen gegen zwei als Gegendruckplatten dienenden Klappen gepreßt werden kann. Während des Verpressens des Stapels wird mittels seitlich vom Stapel angeordneter Aufladeelektroden der Stapel verblockt. Da der Papierstapel eine höhere Dielektrizitätskonstante als Luft aufweist, konzentriert sich das elektrische Feld in diesem. Zusätzlich zu dieser Konzentration ergibt sich eine Feldkonzentration in den überschüssigen Lufteinschlüssen im Stapel, so daß die Feldkraftwirkung im Stapel und die Ladungsansammlung an der Oberfläche die Luft im Stapel verdrängt. Hierdurch wird die Adhäsion der Gegenstände erhöht, wodurch der Stapel mechanisch fest verblockt und infolgedessen gehaltert wird. Während des Pressens des Stapels können seitlich neben dem Stapel angeordneten Aufladeelektroden - je nach Höhe des Stapels - zugeschaltet werden. Such a device is known (WO-96/33118) and has a lifting table, with which one on it overlying stack of stacked objects against two flaps serving as counter pressure plates are pressed can be. During the pressing of the stack by means of charging electrodes arranged on the side of the stack the stack blocked. Because the paper stack is a higher one Dielectric constant as air has concentrated the electric field in this. In addition to this Concentration results in a field concentration in the excess air pockets in the stack so that the Field force effect in the stack and the accumulation of charges the air in the stack displaces the surface. Hereby the adhesion of the objects is increased, whereby the Stack mechanically firmly blocked and as a result is held. Can while pressing the stack charging electrodes arranged to the side of the stack - depending on the height of the stack.

Es sind ähnliche Vorrichtungen zum Verblocken von Stapeln bekannt (DE-44 34 946 A1 und DE-44 41 431 A1), die einen Transporttisch aufweisen, wobei an dem Transporttisch seitliche Aufladeelektroden angeordnet sind, die senkrecht zur Transportrichtung des Stapels verlaufen und sich senkrecht zu dem Transporttisch bis zur vollständigen Höhe des Stapels erstrecken. Dem Transporttisch gegenüberliegend ist eine weitere, geerdete Aufladeelektrode angeordnet, die den Stapel von oben beaufschlagt. Diese Aufladeelektrode kann mit einer oder mehreren Rollen versehen sein, die von oben gegen den Stapel gedrückt werden.They are similar devices for blocking stacks known (DE-44 34 946 A1 and DE-44 41 431 A1), the one Have transport table, being on the transport table lateral charging electrodes are arranged that are perpendicular to the transport direction of the stack and perpendicular to the transport table up to the full height extend the stack. The transport table opposite is another, grounded Charging electrode arranged the stack from above acted upon. This charging electrode can with or be provided with several roles, from above against the Stack are pressed.

Schließlich ist eine Vorrichtung zum Ausrichten, Abpressen und Verblocken von Paketen lose gestapelter Druckerzeugnisse bekannt (G 295 06 231 U1). Diese Vorrichtung besteht aus einem Paketförderer mit einem vorderen heb- und senkbaren Paketanschlag, zwei seitlich vom Paketförderer angeordneten, zusammen- und auseinanderfahrbaren Paketausrichtplatten, einer oberen heb- und senkbaren, zwischen den Paketausrichtplatten auf das zu pressende Paket aufsetzbaren Anpreßeinrichtung. Es weist ein Aufladungsaggregat zum elektrostatischen Verblocken der Druckerzeugnisse auf, dessen Aufladeelektroden an den seitlich von den Paketen angeordneten Paketausrichtplatten und an der Anpreßeinrichtung angeschlossen sind, so daß die Pakete von ihren Seitenwandbereichen und ihrer Oberseite mit Spannung beaufschlagt werden.Finally, there is a device for aligning, pressing and blocking packets loosely stacked Printed products known (G 295 06 231 U1). This Device consists of a package conveyor with a front lifting and lowering package stop, two on the side arranged by the package conveyor, together and separable package alignment plates, an upper can be lifted and lowered between the package alignment plates the pressable package to be pressed on. It has a charging unit for electrostatic Blocking of the printed matter on whose Charging electrodes on the side of the packages arranged package alignment plates and on the Pressure device are connected so that the packages from their side wall areas and their top with Voltage are applied.

Der Erfindung liegt die Aufgabe zugrunde, eine sehr einfache ausgebildete Vorrichtung zum Verblocken eines Stapels von gestapelten Gegenständen, wie z.B. gestapelten Zeitungen, Zeitschriften oder dergleichen, zu schaffen, mit welcher der zu verblockende Stapel sehr effektiv aufgeladen werden kann.The invention has for its object a very simple trained device for blocking a Stacks of stacked items such as stacked To create newspapers, magazines or the like, with which the stack to be blocked is very effective can be charged.

Die Aufgabe wird bei einer gattungsgemäßen Vorrichtung mit den kennzeichnenden Merkmalen des Vorrichtungshauptanspruchs gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen gekennzeichnet.The task with a generic device with the characteristic features of the Device main claim solved. Beneficial Refinements are in the subclaims characterized.

Die erfindungsgemäße Vorrichtung weist Aufladeelektroden zum Aufladen des Stapels auf, die in den einander gegenüberliegenden Preßelementen integriert sind, so daß diese beim Verdichten des Stapels gegen den Stapel gedrückt werden. Zusätzlich können in den Seitenwänden noch Aufladeelektroden vorhanden sein, an die eine positive oder negative Hochspannung angelegt ist, jedenfalls eine andere Polarität als an die obere Aufladeelektrode.The device according to the invention has charging electrodes to charge the stack on top of each other opposing pressing elements are integrated, so that this when compacting the stack against the stack be pressed. In addition, in the side walls charging electrodes are still present on the one positive or negative high voltage is applied, at least a different polarity than the upper one Charging electrode.

Die erfindungsgemäße Vorrichtung ist sehr einfach ausgebildet, denn die aus dem Stand der Technik bekannten, und in der Regel seitlich neben dem zu verblockenden Stapel angeordneten Aufladeelektroden können vollständig entfallen, da diese in die Preßelemente integriert sind.The device according to the invention is very simple trained, because the known from the prior art, and usually to the side of the one to be blocked Stacked charging electrodes can completely omitted, since these are integrated in the pressing elements.

Die sich gegenüberliegenden Preßelemente bilden somit in der Art eines Plattenkondensators ein sich im wesentlichen parallel zur Preßrichtung verlaufendes elektrisches Feld auf, welches die zu stapelnden Gegenstände, wie z.B. Zeitungen, Zeitschriften oder dergleichen, senkrecht durchsetzt, so daß sich an deren Oberflächen die gewünschten Verschiebeladungen ansammeln und ein kapazitives Verschiebefeld aufbauen, das dem von außen angelegten elektrischen Feld entgegengerichtet ist. Da die Richtungen des von außen angelegten elektrischen Feldes und des in den gestapelten Gegenstand induzierten Verschiebefeldes zueinander parallel verlaufen, erfolgt beim Pressen ein kapazitiver Verschiebungsstrom wodurch die Aufladung des Stapels äußerst effektiv ist und wodurch hohe Adhäsionskräfte erzielt werden. Der Verschiebungsstrom erfolgt aufgrund der aus dem Stapel gepreßten Luft.The opposing pressing elements thus form in the type of a plate capacitor essentially one electric field running parallel to the pressing direction which the objects to be stacked, e.g. Newspapers, magazines or the like, vertically interspersed, so that on their surfaces desired shift loads and a build capacitive displacement field, that of the outside applied electric field is opposite. Since the Directions of the external electric field and that induced in the stacked object Shift field run parallel to each other, takes place a capacitive displacement current when pressing the charging of the stack is extremely effective and what high adhesive forces can be achieved. The Displacement current occurs due to the out of the stack compressed air.

Es ist zwar bekannt (WO 96/33118), den als Preßelement dienenden Auflagetisch und die dem Auflagetisch gegenüberliegenden Klappen zu erden bzw. auf ein gleiches Potential zu legen, so daß auch hier ober- und unterhalb des Stapels Aufladeelektroden zum Verblocken desselben vorgesehen sind. Da der Auflagetisch und die Klappen jedoch auf gleiches Potential gelegt sind, und zusätzliche Aufladeelektroden seitlich angeordnet sind, wird ein Feldverlauf erzeugt, der die gestapelten Gegenstände schräg durchsetzt.It is known (WO 96/33118) as the pressing element serving support table and the support table opposite flaps to ground or on an identical To put potential so that here too above and below of the stack of charging electrodes to block the same are provided. Because the support table and the flaps however, have the same potential, and additional Charging electrodes are arranged laterally, a The course of the field creates the stacked objects diagonally interspersed.

Die Seitenwandungen sind mit an ihrem unteren Enden nach außen abgewinkelten Stegen 4, 5 an einer Arbeitsvorrichtung, insbesondere einem Kreuz-Ausleger, befestigt.The inventive device for blocking a Stacks of stacked items such as stacked Newspapers, magazines or the like is considered vertical shaft 1 with two opposite, vertically arranged side walls 2, 3 formed. The side walls are with at their lower ends outside angled webs 4, 5 on one Working device, in particular a cross-jib, attached.

Der Boden des Schachtes 1 wird durch einen vertikal (Pfeil 6) auf und verfahrbaren Hubtisch 7 dargestellt, der aus einer horizontalen Hubplatte 8 und einem Hubzylinder 9 besteht, an dessen oberen Ende die Hubplatte 8 befestigt ist.The bottom of the shaft 1 is a vertical (arrow 6) shown on and movable lifting table 7, the out a horizontal lifting plate 8 and a lifting cylinder 9 there is, at the upper end of the lifting plate 8 attached is.

An den vertikalen Seitenwandungen 2, 3 sind jeweils an ihren oberen horizontalen Längskanten 11, 12 Klappen 13, 14 gelenkig befestigt, so daß die Klappen 13, 14 um die Längskanten 11, 12 zwischen einer horizontalen, in den Schacht 1 vorstehenden Stellung einklappbar und in eine vertikale, in geradliniger Verlängerung zu den Seitenwandungen 2, 3 angeordneten Stellung, ausklappbar sind. In der horizontalen Stellung sind die Klappen 13, 14 durch eine Verriegelungseinrichtung (nicht dargestellt) fixierbar, so daß sie einen beträchtlichen Druck von unten wiederstehen können. In den Klappen 13, 14 sind als Elektrodenplatten 15, 16 ausgebildete Aufladeelektroden eingesetzt, die jeweils gegenüber den übrigen Klappenbereichen der Klappen 13, 14 elektrisch isoliert sind. Vorzugsweise sind die Aufladeelektrodenplatten 15 so ausgebildet, daß sie bei eingeklappten Klappen 13, 14 nach unten etwas an den Klappen 13, 14 vorstehen.On the vertical side walls 2, 3 are in each case their upper horizontal longitudinal edges 11, 12 flaps 13, 14 hinged so that the flaps 13, 14 around the Longitudinal edges 11, 12 between a horizontal, in the Shaft 1 projecting position foldable and in one vertical, in a straight line extension to the Side walls 2, 3 arranged position, foldable are. The flaps 13, 14 are in the horizontal position by a locking device (not shown) fixable so that they have considerable pressure from below can resist. In the flaps 13, 14 are as Electrode plates 15, 16 formed charging electrodes used, each against the rest Flap areas of the flaps 13, 14 electrically isolated are. Preferably, the charging electrode plates 15 are like this trained that after flaps 13, 14 folded protrude slightly from the flaps 13, 14 below.

Die beiden Aufladeelektrodenplatten 15, 16 sind an eine Hochspannungsquelle angeschlossen und können beide vorzugsweise auf das gleiche Potential gelegt werden. Die den beiden Klappen 13, 14 im Schacht 1 gegenüberliegende Hubplatte 8 ist als elektrisch leitende Metallplatte ausgebildet und ist vorzugsweise mit Masse verbunden bzw. wird an eine Spannung angelegt, die die entgegengesetzten Polarität zu der an den Aufladeelektrodenplatten 15, 16 anliegenden Spannung aufweist.The two charging electrode plates 15, 16 are connected to one High voltage source connected and can both preferably put on the same potential. The the two flaps 13, 14 in the shaft 1 opposite Lift plate 8 is an electrically conductive metal plate trained and is preferably connected to ground or is applied to a voltage that the opposite Polarity to that on the charging electrode plates 15, 16 applied voltage.

Figur 2 zeigt eine zweite Ausführungsform der Erfindung, wobei gleich Bezugszeichen gleiche Teile darstellen sollen. Der wesentliche Unterschied zu der Ausführungsform gemäß Figur 1 ist die Verwendung eines Transportbandes 30, welches geerdet und ableitfähig ausgebildet ist. Auf diesem Transportband 30 wird der insgesamt mit 21 bezeichnete Stapel in die Vorrichtung gemäß Figur 2 eingeführt. Dann werden die Seitenwände 2, 3 zum Ausrichten des Stapels seitlich herangefahren. Diese Seitenwände sind zusätzlich mit in sie eingelassenen Elektroden 31, 32 bzw. 33, 34 versehen, die von der restlichen Seitenwand elektrisch isoliert ist.FIG. 2 shows a second embodiment of the invention, where like reference numerals represent like parts should. The main difference from the embodiment 1 is the use of a conveyor belt 30, which is grounded and conductive. On this conveyor belt 30 is the total of 21 designated stack in the device of Figure 2 introduced. Then the side walls 2, 3 to Align the stack to the side. This Side walls are also embedded in them Electrodes 31, 32 and 33, 34 provided by the remaining side wall is electrically insulated.

In weiterer Abweichung von der Ausführungsform gemäß Figur 1 ist das oben angeordnete Preßelement 13 mittels eines schematisch mit 35 bezeichneten, vorzugsweise pneumatischen Hubzylinders bewegbar. In die obere Preßplatte 13 ist eine Aufladeelektrodenplatte 15, ebenfalls elektrisch isoliert eingelassen, die an eine auch Hochspannungsquelle anschließbar ist. Beim Pressen in vertikaler Richtung gemäß Richtungspfeil 6 wird der Stapel 21 verdichtet, wobei durch Austreten der Luft aus den den Stapel 21 bildenden einzelnen Gegenständen 20 ein kapazitiver Verschiebestrom bewirkt wird.In a further deviation from the embodiment according to FIG 1 is the press element 13 arranged above by means of a schematically designated 35, preferably pneumatic lifting cylinder movable. In the top Press plate 13 is a charging electrode plate 15, also insulated electrically, connected to a high-voltage source can also be connected. When pressing in vertical direction according to direction arrow 6 is the stack 21 compressed, whereby by exiting the air from the Stack 21 forming individual objects 20 capacitive displacement current is effected.

Nachfolgend wird die Funktionsweise der erfindungsgemäßen Vorrichtung zum Verblocken eines Stapels anhand Figur 1 erläutert.The mode of operation of the invention is described below Device for blocking a stack using FIG. 1 explained.

Bei geöffneten Klappen 13, 14 werden die zu stapelnden Gegenstände, wie z.B. Zeitungen, Zeitschriften oder dergleichen, von oben in den Schacht 1 eingeführt, wobei sie auf die Hubplatte 8 fallen und durch die Seitenwandungen 2, 3, die als Paketausrichtplatten dienen, ausgerichtet. Haben sich eine vorbestimmte Anzahl von zu stapelnden Gegenständen 20 im Schacht 1 angesammelt, werden die Klappen 13, 14 in ihre horizontale Stellung geklappt und fixiert. Der sich zwischen der Hubplatte 8 und den Klappen 13, 14 befindliche Stapel 21 wird durch Anheben der Hubplatte 8 zwischen den Klappen 13, 14 und der Hubplatte 8 zusammengepreßt und verdichtet. Gleichzeitig wird an die Aufladeelektrodenplatte 15, 16 eine vorbestimmte, vorzugsweise negative Hochspannung angelegt, so daß sich zwischen den Aufladeelektrodenplatten 15, 16 und der mit Masse verbundenen Hubplatte 8 ein elektrisches Feld ausbildet, das die lagenförmig aufeinandergestapelten Gegenständen 20 im wesentlichen senkrecht zu deren Breitseitenflächen durchsetzt. Durch den plötzlichen Spannungsanstieg dU/dt und das gleichzeitige Zusammenpressen des Stapels 21 fließt ein kapazitiver Verschiebestrom dI/dt durch den Stapel 21, der durch den plötzlichen Spannungsanstieg, der gleichzeitigen Erhöhung der Dielektrizitätskonstante sowie einer Verringerung des Widerstandes durch den Preßkontakt zwischen den als Aufladeelektroden wirkenden Aufladeelektrodenplatten 15, 16, dem Stapel 21 und der als Aufladeelektrode wirkenden Hubplatte 8 hervorgerufen wird.When the flaps 13, 14 are open, they are to be stacked Items such as Newspapers, magazines or the like, introduced from above into the shaft 1, wherein they fall on the lifting plate 8 and through the Side walls 2, 3, which serve as package alignment plates, aligned. Have a predetermined number of too stacking objects 20 accumulated in the shaft 1, the flaps 13, 14 are in their horizontal position folded and fixed. The between the lifting plate 8th and the flaps 13, 14 located stack 21 is by Lifting the lifting plate 8 between the flaps 13, 14 and the lifting plate 8 is compressed and compressed. At the same time, the charging electrode plate 15, 16 a predetermined, preferably negative high voltage created so that between the Charging electrode plates 15, 16 and the one with ground connected lifting plate 8 forms an electric field, the objects 20 stacked on top of one another in layers essentially perpendicular to their broad side surfaces enforced. Due to the sudden voltage increase dU / dt and simultaneously compressing the stack 21 a capacitive displacement current dI / dt flows through the Stack 21, which is caused by the sudden increase in voltage simultaneous increase in the dielectric constant as well a reduction in resistance through the press contact between those acting as charging electrodes Charging electrode plates 15, 16, the stack 21 and the as Charging electrode acting lifting plate 8 is caused.

Durch die unmittelbare Kontaktierung der Aufladeelektrodenplatten 15, 16 mit dem Stapel 21 wird gegenüber der aus dem Stand der Technik bekannten kontaktlosen Übertragung der elektrischen Ladung ein verbesserter Wirkungsgrad erzielt, weshalb der mit der erfindungsgemäßen Vorrichtung eingesetzte Hochspannungsgenerator kleiner als die bei der bekannten Vorrichtungen zum Verblocken verwendeten Hochspannungsgeneratoren ausgelegt werden kann.By contacting the Charging electrode plates 15, 16 with the stack 21 is compared to that known from the prior art contactless transmission of electrical charge improved efficiency achieved, which is why with the device used according to the invention High voltage generator smaller than that of the known one Blocking devices used High voltage generators can be designed.

Eine Verstellung bzw. Anpassung der Aufladeelektroden an die Stapelhöhe des im Schacht 1 befindlichen Stapels 21 von zu stapelnden Gegenständen 20 erfolgt bei der erfindungsgemäßen Vorrichtung selbsttätig, da die Aufladeelektroden an den sich gegenüberliegenden Preßelementen ausgebildet sind, zwischen welchen der zu verblockende Stapel 21 gepreßt wird.An adjustment or adjustment of the charging electrodes the stack height of the stack 21 located in the shaft 1 of objects to be stacked 20 takes place at the device according to the invention automatically since the Charging electrodes on the opposite Press elements are formed, between which of the blocking stack 21 is pressed.

Da die Aufladeelektrodenflächen mechanisch mit den zu stapelnden Gegenständen kontaktiert werden, können sich daran keine Verschmutzungen anlagern, wie es bei den herkömmlich verwendeten, kontaktlos arbeitenden Hochspannungselektroden bekannt ist, die in regelmäßigen Abständen, oftmals innerhalb weniger Tage, gereinigt werden müssen.Since the charging electrode surfaces mechanically with the stacking objects can be contacted do not accumulate any dirt on it, as is the case with conventionally used, contactless working High voltage electrodes are known to be used in regular Intervals, often within a few days, cleaned Need to become.
