Definitions
- the invention relates to a device for forming stacks of flat parts, in particular sheets such as sheets of paper, in a stacking area with substantially uninterrupted conveyance of the flat parts to the stacking area, with a main stack support on which the flat parts are stackable, and a Hiffsstapelisme, after reaching a predetermined number of stacked on the main stack carrier flat parts over the then formed by the predetermined number of flat parts on the main stack carrier finished stack in the stack area can be brought to receive subsequent flat parts stacked, the main stack support provided for the removal of the finished stack and in the empty state can be brought under the auxiliary stack carrier located in the stack area and wherein the auxiliary stack carrier for the transfer of the part stack formed on the auxiliary stack carrier up to this time on the main stack carrier from the stack area is retractable.
- Critical is the transfer of the sub-stack of withdrawing from the stack area auxiliary stack carrier on the main stack carrier. Because the auxiliary stack carrier has a certain thickness, arises in the moment in which the sub-stack leaves the auxiliary stack carrier and deposits on the main stack carrier, in the lower portion of the sub-stack a shaft. As a result of the formation of such a shaft, the lower region of the partial stack is not stored vertically but offset relative to the remaining section of the partial stack. This disadvantageous effect can be further enhanced by a friction occurring between the upper side of the auxiliary pile carrier and the underside of the partial stack, whereby the lower layers of the partial stack can be taken along during the retraction movement of the auxiliary pile carrier from the stack area.
- a second auxiliary stack carrier in addition to a first auxiliary stack carrier, a second auxiliary stack carrier is provided.
- the second auxiliary stack carrier is disposed on the opposite side of the stack area with respect to the first auxiliary stack carrier. After retracting the first auxiliary stack carrier and reaching a position of the second auxiliary stack carrier opposite thereto, the second auxiliary stack carrier is moved synchronously with the rewinding of the first auxiliary stack carrier to a middle position in the stacking area and then withdrawn from the stack area in opposite directions synchronously with the extension of the first auxiliary stack carrier.
- the partial stack formed thereupon then deposits on a pallet which lies on the main stack carrier which is already located below the plane formed by the two auxiliary stack carriers. Although in each case forms a wave at the mutually facing ends of the two auxiliary stack carrier. However, since these two shafts are directed opposite to each other, a compensation results, so that is stored by the synchronous symmetrical extension of the two auxiliary stack carrier of the sub-stack substantially without edge offset. Not least, the arrangement of a second auxiliary stack carrier requires in this known device a complex construction and complicated control, which is also reflected adversely in increased manufacturing, operating and maintenance costs.
- a stacking device for stacking a stack of flat material layers in which initially on a pallet an initial stack between a vibrating Ausrichtanschlag and a facing aligner is piled so that the edge region lying at the Ausrichtanschlag over the pallet. Then, a pallet is lowered with the supporting this lowering table such that the edge area runs onto an under him driven auxiliary table and is raised with this slightly above the level of the support surface of the pallet.
- the pallet can then be moved with a slider under the starting stack, the registration fence and the auxiliary table so that all the stacking edges are set back from the outer limits of the pallet, after which the auxiliary table is retracted and the raised edge area under guidance falls on the bearing surface on the alignment surface of the stopped alignment stop. Then the stack is stacked to its full height.
- the object is achieved by an apparatus for forming stacks of flat parts, in particular sheets, such as paper sheets, in a stacking area with substantially uninterrupted conveyance of the flat parts to the stacking area, with a main stack carrier on which the flat parts can be stacked , and an auxiliary stack carrier, which after reaching a predetermined number of stacked on the main stack carrier flat parts over the then formed by the predetermined number of flat parts on the main stack carrier finished stack in the stack area can be brought to receive subsequent flat parts stacked, wherein the main stack carrier for the removal provided in the finished stack and can be brought in the empty state under the auxiliary stack carrier located in the stack area and wherein the auxiliary stack carrier for the transfer of the formed up to this time on the auxiliary stack carrier part Stackable on the main stack support from the stack area is retractable, characterized in that at least one of the top at least partially forming portion of the main stack support is at least substantially opposite to the direction of retraction movement of the auxiliary stack support movable and that a control
- the invention proposes to make at least one portion of the main stack carrier at least partially forming in the direction of the retracting movement of the auxiliary stack carrier movable and movement of at least this uppermost at least partially forming portion of the main stack carrier substantially opposite to the retraction movement to use the auxiliary stack carrier for the compensation of an S-beat or offset in the lower part of the sub-stack.
- this feed movement according to the invention forming a compensation movement, the leading edge of the lower region of the sub-stack is again pushed vertically under the remaining section of the sub-stack so that the formation of an S-impact or offset is prevented or at least reduced to a minimum in this manner.
- the path length should be at least equal to the movement substantially opposite to the retraction movement of the auxiliary pile carrier the top of at least partially forming portion of the main stack support be individually adjustable and thus adjustable.

- the entire main stack carrier may be designed to be movable substantially opposite to the retraction movement of the auxiliary stack carrier.
- the advancing movement of the auxiliary stack support substantially opposite to the retraction movement of at least the uppermost at least partially forming section of the main stack support should only be initiated after the auxiliary stack support has already carried out its retraction movement by a predeterminable distance.
- the fact is taken into account that sufficient friction occurs when already a part of the sub-stack rests on the main stack support in order to then be able to take them accordingly by the feed movement.
- a movable receiving element preferably a pallet, is placed on the main stack carrier for receiving and transporting the stack.
- At least the portion of the main stack carrier forming the upper side at least in part should perform an upward movement in addition to its feed motion substantially opposing the retraction movement of the auxiliary stack carrier, in order to be able to compensate at least the thickness of the retracting or already retracted auxiliary stack carrier.
- substantially the entire main stack carrier can perform such an upward movement. This additional upward movement should take place at least until the upper side of the main stack carrier or the upper side of the receiving element located on the main stack carrier reaches approximately the level of the upper side of the previously completely retracted auxiliary stack carrier.

- the separating finger 20 forms a further partial stack 30a, which rests on the finished stack of sheets 30 and slowly grows due to the uninterrupted promotion of further sheet 10.
- the inserted separating finger 20 defines a first virtual parting line 32 between the lower finished sheet stack 30 and the partial stack 30a growing above it FIG. 3 can also recognize.
- control device now controls the movement of the separating finger 20 such that the lowering of the separating finger 20 with respect to the lowering speed of the main stacking platform 14 is slower. Due to the faster lowering of the main stacking platform 14 continues in the direction of now FIG. 4 Arrow D shown opposite to the lowering of the separating finger 20 forms a in FIG. 4 recognizable gap 34, which is bounded down from the top of the finished stack 30 at the level of the first dividing line 32 and upwards from a now formed by the separating finger 20 second virtual parting line 36.
- FIG. 5 shows, the separating shoe 24 is now inserted in this gap 34 in the horizontal direction according to arrow E.

Since the size of the aforementioned wave may be variable depending on the type of paper, the length of the section, the height of the sub-stack 30a formed up to this point, the geometry of pulling out the auxiliary stacking platform 26 and other factors, the magnitude of the horizontal lifting movement should be variable according to arrow H. be adjustable. In this context, it is beneficial to the movement controlled by adding a suitable sensor instead of being controlled.
- the horizontal movement according to arrow H should also be synchronous to the vertical stroke according to arrow V. It is conceivable that this synchronization is not linear, but an arbitrary, predetermined curve follows. The control of this sequence of movements is also taken over by the already mentioned control device.
- the pallet applicator 28 is moved back to its rest position outside the stacking point 2.

In der papierverarbeitenden Industrie werden an sog. Sammelstationen einzelne Bogen, die beispielsweise von einer Schneideeinrichtung durch Abschneiden von einer laufenden Bahn gebildet wurden, fortlaufend, d.h. ununterbrochen, zu einem Stapelbereich gefördert und dort zu Stapeln übereinander gelegt. Während dieser Ansammlung von Bogen im Stapelbereich müssen gewöhnlich die Stapel mit einer definierten vorgegebenen Anzahl von Bogen zur Weiterverarbeitung vom Stapelbereich wegbefördert werden. Um aber eine Unterbrechung des Betriebes der gesamten Maschine zu verhindern, bleibt die ununterbrochene Zuförderung von Bogen in den Stapelbereich bestehen. Während der Übemahme eines fertigen Stapels vom Hauptstapelträger übernimmt temporär ein Hilfsstapelträger das weitere Aufstapeln der ununterbrochenen zugeförderten Bogen im Stapelbereich, und zwar so lange, bis der leere Hauptstapelträger den bis dahin gebildeten Teilstapel vom Hilfsstapelträger übernimmt. Hierzu wird der Hilfsstapelträger in den Stapelbereich verbracht und anschließend wieder entfernt.In the paper processing industry, individual sheets which have been formed, for example, by a cutting device by cutting off a moving web, are conveyed continuously, ie continuously, to a stack area at stacking stations where they are stacked one above the other. During this accumulation of sheets in the stacking area, usually the stacks having a defined predetermined number of sheets must be carried away from the stacking area for further processing. But to prevent interruption of the operation of the entire machine, the continuous feed of sheets remains in the stack area. During the exercise a finished stack of the main stack carrier temporarily assumes an auxiliary stack carrier further stacking the uninterrupted conveyed sheet in the stack area, and that until the empty main stack carrier takes over the partial stack formed by then from the auxiliary stack carrier. For this purpose, the auxiliary stack carrier is placed in the stack area and then removed again.
Kritisch ist die Übergabe des Teilstapels vom sich aus dem Stapelbereich zurückziehenden Hilfsstapelträger auf den Hauptstapelträger. Denn da der Hilfsstapelträger eine bestimmte Dicke besitzt, entsteht in dem Moment, in dem der Teilstapel den Hilfsstapelträger verlässt und sich auf dem Hauptstapelträger ablegt, im unteren Abschnitt des Teilstapels eine Welle. Durch die Ausbildung einer solchen Welle wird der untere Bereich des Teilsstapels nicht lotrecht, sondern gegenüber dem darüber liegenden übrigen Abschnitt des Teilsstapels versetzt abgelegt. Verstärkt werden kann dieser nachteilige Effekt noch durch eine zwischen der Oberseite des Hilfsstapelträgers und der Unterseite des Teilsstapels entstehende Reibung, wodurch während der Rückziehbewegung des Hilfsstapelträgers aus dem Stapelbereich die unteren Lagen des Teilsstapels mitgenommen werden können. Wenn nun der Hauptstapelträger eine ausgleichende Hubbewegung in vertikaler Richtung nach oben ausführt, um die Dicke des bis dahin bereits aus dem Stapelbereich herausgefahren Hilfsstapelträgers zu kornpensieren, setzt sich der durch die Welle gebildete Versatz des unteren Bereiches bzw. der unteren Lagen des Teilstapels in Richtung der Rückziehbewegung des Hilfsstapelträgers bis zum Ende fort. Somit entsteht ein Absatz im Stapel, der auch als sog. S-Schlag bezeichnet wird. Ein solcher Absatz stellt jedoch regelmäßig einen Qualitätsmangel dar. Denn gerade in der papierverarbeitenden Industrie besteht gewöhnlich die Forderung, im wesentlichen gerade Stapelkanten zu erzeugen, um die spätere Verarbeitung der Bogen nicht zu behindern, was insbesondere bei hochwertigen Papieren von besonderer Wichtigkeit ist.Critical is the transfer of the sub-stack of withdrawing from the stack area auxiliary stack carrier on the main stack carrier. Because the auxiliary stack carrier has a certain thickness, arises in the moment in which the sub-stack leaves the auxiliary stack carrier and deposits on the main stack carrier, in the lower portion of the sub-stack a shaft. As a result of the formation of such a shaft, the lower region of the partial stack is not stored vertically but offset relative to the remaining section of the partial stack. This disadvantageous effect can be further enhanced by a friction occurring between the upper side of the auxiliary pile carrier and the underside of the partial stack, whereby the lower layers of the partial stack can be taken along during the retraction movement of the auxiliary pile carrier from the stack area. Now, if the main stack carrier executes a compensatory lifting movement in a vertical upward direction in order to grainpill the thickness of the auxiliary stack carrier already moved out of the stacking area, the offset of the lower region or of the lower layers of the partial stack formed by the shaft is set in the direction of Retraction of the auxiliary pile carrier continues to the end. Thus, a paragraph in the stack, which is also referred to as a so-called. S-blow. However, such a paragraph is regularly a quality defect. Especially in the paper processing industry there is usually the demand to produce substantially straight stack edges, so as not to hinder the subsequent processing of the sheets, which is of particular importance for high-quality papers.

Es ist Aufgabe der vorliegenden Erfindung, eine gegenüber dem Stand der Technik konstruktiv und steuerungstechnisch vereinfachte Lösung anzugeben, die gleichwohl einen Nonstop-Stapelwechsel ohne Beeinträchtigung der Stapelqualität gestattet.It is an object of the present invention to provide a comparison with the prior art constructive and control technology simplified solution that nonetheless allows a non-stop stack change without affecting the stack quality.

- c) to stack subsequent flat parts on the auxiliary pile carrier,

- e) spend the then empty main stack carrier under the auxiliary stack carrier and
- f) withdraw the auxiliary pile carrier from the stacking area to thereby transfer the partial stack formed on the auxiliary pile carrier to the main pile carrier until then;
Gemäß einem zweiten Aspekt der vorliegenden Erfindung wird die Aufgabe gelöst durch eine Vorrichtung zur Bildung von Stapeln von Flachteilen, insbesondere Bogen wie beispielsweise Papierbogen, in einem Stapelbereich unter im wesentlichen ununterbrochener Förderung der Flachteile zum Stapelbereich, mit einem Hauptstapelträger, auf dem die Flachteile stapelbar sind, und einem Hilfsstapelträger, der nach Erreichen einer vorgebbaren Anzahl von auf dem Hauptstapelträger gestapelten Flachteilen über dem dann durch die vorgebbare Anzahl von Flachteilen auf dem Hauptstapelträger gebildeten fertigen Stapel in den Stapelbereich verbringbar ist, um nachfolgende Flachteile gestapelt aufzunehmen, wobei der Hauptstapelträger für die Entnahme des fertigen Stapels vorgesehen und im leeren Zustand unter den im Stapelbereich befindlichen Hilfsstapelträger verbringbar ist und wobei der Hilfsstapelträger für die Übergabe des bis zu diesem Zeitpunkt auf dem Hilfsstapelträger gebildeten Teilstapels auf den Hauptstapelträger aus dem Stapelbereich zurückziehbar ist, dadurch gekennzeichnet, dass zumindest ein die Oberseite mindestens teilweise bildender Abschnitt des Hauptstapelträgers zumindest im wesentlichen entgegengesetzt zu der Richtung der Rückziehbewegung des Hilfsstapelträgers bewegbar ausgeführt ist und dass eine Steuerungseinrichtung vorgesehen ist, die die Bewegung zumindest des die Oberseite mindestens teilweise bildenden Abschnittes des Hauptstapelträgers in dessen unter den Hilfsstapelträger verbrachten Zustand derart steuert, dass zumindest der die Oberseite mindestens teilweise bildende Abschnitt des Hauptstapelträgers im wesentlichen entgegengesetzt zu der Rückziehbewegung des Hilfsstapelträgers eine Vorschubbewegung ausführt, um den Teilstapel durch diese Vorschubbewegung entsprechend mitnehmen zu können, während der Hilfsstapelträger aus dem Stapelbereich zurückgezogen wird und/oder nachdem der Hilfsstapelträger aus dem Stapelbereich zurückgezogen worden ist.According to a second aspect of the present invention, the object is achieved by an apparatus for forming stacks of flat parts, in particular sheets, such as paper sheets, in a stacking area with substantially uninterrupted conveyance of the flat parts to the stacking area, with a main stack carrier on which the flat parts can be stacked , and an auxiliary stack carrier, which after reaching a predetermined number of stacked on the main stack carrier flat parts over the then formed by the predetermined number of flat parts on the main stack carrier finished stack in the stack area can be brought to receive subsequent flat parts stacked, wherein the main stack carrier for the removal provided in the finished stack and can be brought in the empty state under the auxiliary stack carrier located in the stack area and wherein the auxiliary stack carrier for the transfer of the formed up to this time on the auxiliary stack carrier part Stackable on the main stack support from the stack area is retractable, characterized in that at least one of the top at least partially forming portion of the main stack support is at least substantially opposite to the direction of retraction movement of the auxiliary stack support movable and that a control device is provided which at least the movement the top of at least partially forming portion of the main stack carrier in its under the auxiliary stack carrier state is controlled so that at least the top at least partially forming portion of the main stack carrier substantially opposite to the retraction movement of the auxiliary stack carrier performs a feed movement to take along the sub-stack by this feed movement accordingly may be withdrawn from the stacking area while the auxiliary stacking carrier is retracted and / or after the auxiliary stacking carrier has been retracted from the stacking area has been pulled back.
Demgemäß schlägt die Erfindung vor, zumindest einen die Oberseite mindestens teilweise bildenden Abschnitt des Hauptstapelträgers in Richtung der Rückziehbewegung des Hilfsstapelträgers bewegbar auszuführen und eine Bewegung zumindest dieses die Oberseite mindestens teilweise bildenden Abschnittes des Hauptstapelträgers im wesentlichen entgegengesetzt zu der Rückziehbewegung des Hilfsstapelträgers für die Kompensation eines S-Schlages bzw. Versatzes im unteren Bereich des Teilstapels zu nutzen. Durch diese erfindungsgemäße eine Ausgleichsbewegung bildende Vorschubbewegung wird die Vorderkante des unteren Bereiches des Teilstapels wieder lotrecht unter den darüber liegenden übrigen Abschnitt des Teilstapels geschoben, so dass auf diese Weise die Ausbildung eines S-Schlages bzw. Versatzes verhindert oder zumindest auf ein Minimum reduziert wird. Da die Größe des S-Schlages abhängig von dem Material der Flachteile, deren Länge, der Höhe des Teilstapels, der Geometrie beim Zurückziehen des Hilfsstapelträgers und anderen Faktoren sein kann, sollte die Weglänge bei der zu der Rückziehbewegung des Hilfsstapelträgers im wesentlichen entgegengesetzten Bewegung zumindest des die Oberseite mindestens teilweise bildenden Abschnittes des Hauptstapelträgers individuell einstellbar und somit einstellbar sein.Accordingly, the invention proposes to make at least one portion of the main stack carrier at least partially forming in the direction of the retracting movement of the auxiliary stack carrier movable and movement of at least this uppermost at least partially forming portion of the main stack carrier substantially opposite to the retraction movement to use the auxiliary stack carrier for the compensation of an S-beat or offset in the lower part of the sub-stack. As a result of this feed movement according to the invention forming a compensation movement, the leading edge of the lower region of the sub-stack is again pushed vertically under the remaining section of the sub-stack so that the formation of an S-impact or offset is prevented or at least reduced to a minimum in this manner. Since the size of the S-beating may be dependent on the material of the flat parts, their length, the height of the sub-stack, geometry in retracting the auxiliary pile carrier, and other factors, the path length should be at least equal to the movement substantially opposite to the retraction movement of the auxiliary pile carrier the top of at least partially forming portion of the main stack support be individually adjustable and thus adjustable.
Nicht zuletzt weil die Erfindung auf die Verwendung eines weiteren Hilfsstapelträger und sonstiger Hilfsmittel verzichtet, bietet die Erfindung eine konstruktiv und steuerungstechnisch einfache, jedoch wirkungsvolle Lösung.Not least because the invention dispenses with the use of a further auxiliary stack carrier and other auxiliaries, the invention offers a structurally and control-technically simple, but effective solution.
Zwar ist es beispielsweise aus der
Ferner offenbart zwar auch die
Im übrigen ist es grundsätzlich auch denkbar, alternativ oder zusätzlich zu dem zumindest einen die Oberseite mindestens teilweise bildenden Abschnitt des Hauptstapelträgers zumindest ein die Oberseite mindestens teilweise bildenden Abschnitt des Hilfsstapelträgers eine Bewegung im wesentlichen entgegengesetzt zu der Rückziehbewegung des Hilfsstapelträgers ausführen zu lassen. Hierzu kann sich beispielsweise ein entsprechend angetriebenes Tuch eignen.Moreover, it is also conceivable in principle, alternatively or in addition to the at least one of the top at least partially forming portion of the main stack support at least one of the top at least partially forming Section of the auxiliary pile carrier to perform a movement substantially opposite to the retracting movement of the auxiliary pile carrier. For this purpose, for example, a suitably driven cloth are suitable.
Bevorzugte Ausführungen und Weiterbildungen der vorliegenden Erfindung sind in den abhängigen Ansprüchen angegeben.Preferred embodiments and further developments of the present invention are specified in the dependent claims.
Vorzugsweise kann der Hauptstapelträger einen mindestens teilweise seine Oberseite bildenden Ablagetisch aufweisen, der sich gegenüber dem übrigen Abschnitt des Hauptstapelträgers im wesentlichen entgegengesetzt zu der Rückziehbewegung des Hilfsstapelträgers bewegt.Preferably, the main stack support may have an at least partially forming its top tray table, which moves relative to the remaining portion of the main stack carrier substantially opposite to the retraction movement of the auxiliary stack carrier.
Alternativ ist es auch denkbar, beispielsweise den Hauptstapelträger mit einem endlos umlaufenden Förderband zu versehen, dessen oberer Trum mindestens teilweise die Oberseite des Hauptstapelträgers bildet und sich im wesentlichen entgegengesetzt zur Rückziehbewegung des Hilfsstapelträgers bewegt.Alternatively, it is also conceivable, for example, to provide the main stack support with an endlessly circulating conveyor belt whose upper run at least partially forms the top of the main pile support and moves substantially opposite to the retraction movement of the auxiliary pile support.
Schließlich kann auch der gesamte Hauptstapelträger im wesentlichen entgegengesetzt zu der Rückziehbewegung des Hilfsstapelträgers bewegbar ausgeführt sein.Finally, the entire main stack carrier may be designed to be movable substantially opposite to the retraction movement of the auxiliary stack carrier.
Zweckmäßigerweise sollte die zur Rückziehbewegung des Hilfsstapelträgers im wesentlichen entgegengesetzte Vorschubbewegung zumindest des die Oberseite mindestens teilweise bildenden Abschnittes des Hauptstapelträgers erst dann eingeleitet werden, nachdem der Hilfsstapelträger seine Rückziehbewegung bereits um eine vorgebbare Distanz ausgeführt hat. Bei dieser Ausführung wird dem Umstand Rechnung getragen, dass genügend Reibung entsteht, wenn bereits ein Teil des Teilstapels auf dem Hauptstapelträger aufliegt, um diesen dann durch die Vorschubbewegung entsprechend mitnehmen zu können.Expediently, the advancing movement of the auxiliary stack support substantially opposite to the retraction movement of at least the uppermost at least partially forming section of the main stack support should only be initiated after the auxiliary stack support has already carried out its retraction movement by a predeterminable distance. In this embodiment, the fact is taken into account that sufficient friction occurs when already a part of the sub-stack rests on the main stack support in order to then be able to take them accordingly by the feed movement.
Gewöhnlich wird ein bewegliches Aufnahmeelement, vorzugsweise eine Palette, zur Aufnahme und zum Transport des Stapels auf dem Hauptstapelträger aufgelegt.Usually, a movable receiving element, preferably a pallet, is placed on the main stack carrier for receiving and transporting the stack.
Ferner sollte vorzugsweise mindest der die Oberseite mindestens teilweise bildenden Abschnitt des Hauptsstapelträgers zusätzlich zu seiner zur Rückziehbewegung des Hilfsstapelträgers im wesentlichen entgegengesetzten Vorschubbewegung im wesentlichen zeitgleich eine Aufwärtsbewegung ausführen, um zumindest die Dicke des sich zurückziehenden oder bereits zurückgezogenen Hilfsstapelträgers entsprechend zu kompensieren zu können. Hierzu ist es denkbar, dass im wesentlichen der gesamte Hauptstapelträger eine solche Aufwärtsbewegung ausführen kann. Diese zusätzliche Aufwärtsbewegung sollte zumindest so lange stattfinden, bis die Oberseite des Hauptstapelträgers oder die Oberseite des auf dem Hauptstapelträger liegenden Aufnahmeelementes etwa das Niveau der Oberseite des bis dahin bereits vollständig zurückgezogenen Hilfsstapelträgers erreicht.Furthermore, preferably at least the portion of the main stack carrier forming the upper side at least in part should perform an upward movement in addition to its feed motion substantially opposing the retraction movement of the auxiliary stack carrier, in order to be able to compensate at least the thickness of the retracting or already retracted auxiliary stack carrier. For this purpose, it is conceivable that substantially the entire main stack carrier can perform such an upward movement. This additional upward movement should take place at least until the upper side of the main stack carrier or the upper side of the receiving element located on the main stack carrier reaches approximately the level of the upper side of the previously completely retracted auxiliary stack carrier.
Bei Verwendung eines Trennmittels, vorzugsweise mindestens eines Trennschuhs, welcher im Stand der Technik bereits zumeist eingesetzt wird, sollte zumindest der die Oberseite mindestens teilweise bildende Abschnitt des Hauptstapelträgers seine zur Rückziehbewegung des Hilfsstapelträgers im wesentlichen entgegengesetzte Vorschubbewegung ausführen, während sich das Trennmittel noch im Stapelbereich befindet und vorzugsweise bis dieses aus dem Stapelbereich entfernt worden ist.When using a release agent, preferably at least one separation shoe, which is already mostly used in the prior art, at least the top of the main stack carrier at least partially perform its for retraction of the auxiliary stack carrier substantially opposite feed movement, while the release agent is still in the stacking area and preferably until it has been removed from the stacking area.
Für die zuvor beschriebenen Bewegungsabläufe ist eine entsprechende Steuerungseinrichtung vorzusehen. Vorzugsweise steuert die Steuerungseinrichtung die Aufwärtsbewegung im wesentlichen zeitgleich mit der zur Rückziehbewegung des Hilfsstapelträgers im wesentlichen entgegengesetzten Vorschubbewegung. Hierzu kann für die zur Rückziehbewegung des Hilfsstapelträgers im wesentlichen entgegengesetzte Vorschubbewegung ein erstes Antriebsmittel und für die Aufwärtsbewegung ein zweites Antriebsmittel vorgesehen sein, wobei diese beiden Antriebsmittel von der Steuerungseinrichtung entsprechend angesteuert werden. Bei dieser Weiterbildung ist es von Vorteil, dass der resultierende Bewegungsweg einer beliebigen, einstellbaren Kurve folgen kann. Alternativ ist es aber auch denkbar, dass die Steuerungseinrichtung mindestens eine Kulissenführung zur mechanischen Führung zumindest des die Oberseite mindestens teilweise bildenden Abschnittes des Hauptstapelträgers aufweist.For the motion sequences described above, a corresponding control device is provided. Preferably, the control means controls the upward movement substantially simultaneously with the feed movement substantially opposite to the retraction movement of the auxiliary pile carrier. For this purpose, a first drive means and for the upward movement, a second drive means may be provided for the retraction movement of the auxiliary stack carrier substantially opposite feed movement, said two drive means are controlled by the control device accordingly. In this development, it is advantageous that the resulting path of movement can follow an arbitrary, adjustable curve. Alternatively, it is also conceivable that the control device at least one slotted guide for has mechanical guide at least the top of the at least partially forming portion of the main stack carrier.
