Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Vereinzeln von Postgut, das in Form von flachen rechteckförmigen, insbesondere briefartigen Stückgütern (1) vorliegt, aus einem Stapel eines Stapelmagazines (2) mittels einer Abzieheinrichtung (z.B. 4), die ein im wesentlichen transversal zur Stapelrichtung bewegbares Abziehorgan (z.B. 3) für das jeweils zu entnehmende Stückgut (1) aufweist,

  • wobei die Stapelrichtung eine senkrechte Komponente aufweist
  • wobei das Abziehorgan auf der Unterseite des Stapels angeordnet ist,
  • wobei auf der Unterseite des Stapelmagazins (2) seitlich des Abziehorganes zum Begrenzen der Nachrutschbewegung des gestapelten Stückguts (1) zumindest ein in den Stapelbereich hineinragender Anschlag (13) vorgesehen ist, und wobei Abziehorgan und

  • The invention relates to a device for separating mail, which is in the form of flat rectangular, in particular letter-like piece goods (1), from a stack of a stack magazine (2) by means of a pulling device (for example 4), which is essentially transverse to the stacking direction has a movable puller (for example 3) for the piece goods (1) to be removed in each case,
  • wherein the stacking direction has a vertical component
  • the puller being located on the underside of the stack,
  • at least one stop (13) protruding into the stacking area is provided on the underside of the stacking magazine (2) to the side of the pulling element to limit the sliding movement of the stacked piece goods (1), and wherein pulling element and
  • wherein a bearing surface of the puller in the stacking direction relative to the stop in its height can be changed in time with the pulling process.
  • Eine ähnliche Vorrichtung ist z.B. durch die US-A-5,552,859 bekannt geworden, wonach ein Papierstapel in einen Behälter einlegbar ist, dessen Boden einen fensterartigen Durchbruch aufweist, unter dem eine teilkreisförmige Antriebsrolle angeordnet ist. Deren Außenkontur ist in der Art einer Kurvenscheibe so ausgebildet und angeordnet, daß sie sich in der Ruhelage unterhalb des Bodens befindet. Um das unterste Blatt aus dem Stapel herauszuziehen, wird die Antriebsrolle verdreht und greift dabei mit ihrem vergrößerten Abschnitt in den Stapelbereich, wodurch das unterste Blatt in der Drehrichtung verschoben wird. Der Übergang zum erweiterten Abschnitt ist eckig ausgebildet, sodaß sich während der Drehung ein in der Stapelrichtung wirkender Bewegungsimpuls ergibt. A similar device is e.g. by US-A-5,552,859 became known, after which a stack of paper in a container is insertable, the bottom of a window-like opening has, under which a part-circular drive roller is arranged. Their outer contour is like a Cam designed and arranged so that it is in the rest position is located below the ground. To the bottom Pulling sheet out of the stack becomes the drive roller twists and engages with its enlarged section the stacking area, making the bottom sheet in the Direction of rotation is shifted. The transition to the expanded Section is angular, so that during the Rotation a movement impulse acting in the stacking direction results.

    Ferner ist durch die US-A-5,511,936 eine Vereinzelungsvorrichtung für Briefe bekannt, bei der die Stückgüter von der Oberseite eines Stapels mittels eines Sauggreifers angehoben und mittels umlaufender Riemen abtransportiert werden.Furthermore, US-A-5,511,936 one Separation device for letters known, in which the General cargo from the top of a stack using a Suction cup raised and by means of circumferential straps be transported away.

    Eine andere Einrichtung zum Vereinzeln von flachem Postgut ist z.B. durch die US 3,861,669 bekannt geworden. Danach werden gestapelte Briefe mittels eines Transportbandes vereinzelt, das mit Hilfe einer Saugöffnung den jeweils nächsten Brief ansaugt und aus dem Stapel herauszieht. Dabei drückt der nachfolgende Brief auf den herauszuziehenden, was das Abziehen erschwert. Insbesondere bei dünnen Briefen ist es möglich, daß der nachfolgende Brief aufgrund der Haftreibung mitgezogen wird, vorallem wenn der erste Brief zum Teil herausgezogen ist und der nächste gegen das Förderband gedrückt wird.Another device for separating flat mail is e.g. made known by US 3,861,669. After that letters are stacked using a conveyor belt isolated, the each with the help of a suction opening sucks the next letter and pulls it out of the stack. there the following letter presses on what to extract pulling off difficult. Especially with thin letters it is possible that the following letter due to the Stiction is dragged, especially when the first letter partially pulled out and the next against that Conveyor belt is pressed.

    Der Erfindung liegt die Aufgabe zugrunde, die Funktionssicherheit beim Vereinzeln des Stückgutes zu erhöhen. Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst.The invention is based, which Functional reliability when separating the piece goods increase. This object is achieved by the invention Claim 1 solved.

    Bei dem Stapelmagazin mit einer senkrechten Komponente ergibt sich das Problem, daß der Stapeldruck bei großer Stapelhöhe sehr hoch sein kann. Durch den auf den Stapel ausgeübten Impuls wird dieser Druck zumindest zeitweise verringert, die Haftreibung zwischen den benachbarten Stückgütern verringert und ein klebeartiges Aneinanderhaften der beiden unteren Stückgüter vermieden. Gleichzeitig wird das unterste Stückgut vom Abziehorgan erfaßt und transversal zur Stapelrichtung in Bewegung versetzt.For the stacking magazine with a vertical component the problem is that the stack pressure at high stack height can be very high. By exercising on the stack This pressure is at least temporarily reduced by the momentum Stiction between the neighboring general cargo is reduced and a sticky sticking together of the bottom two General cargo avoided. At the same time, the bottom general cargo gripped by the puller and transversely to the stacking direction in Moves.

    Dabei ist die Gefahr, daß das nächste Stückgut mitgenommen wird, erheblich verringert. Durch die rückseitigen schmalen Anschlagflächen kann das unterste Stückgut in kurzer Zeit aus deren Bereich entfernt werden, bevor sich der volle Stapeldruck der nachrutschenden restlichen Stückgüter wieder aufbaut. Da dann der Anschlag bereits wieder oberhalb der Auflagefläche des Abziehorgans angeordnet sein kann, ist es möglich, den Reststapel solange mit Abstand zurückzuhalten, bis das unterste Stückgut ohne Druck aus dem Stapelbereich heraus bewegt worden ist.There is a risk that the next general cargo will be taken away is significantly reduced. Through the narrow back The bottom cargo can be removed from the bottom surface in a short time whose area must be removed before the full Stack printing of the slipping remaining piece goods again builds. Then the stop is already above the Support surface of the puller can be arranged, it is possible to keep the remaining stack at a distance, until the bottom general cargo without pressure from the stacking area has been moved out.

    Durch den diagonalen Abzug wird erreicht, daß auch unterschiedlich große Stückgüter vom Förderband sicher erfaßt werden. Dieses ist dabei so angeordnet, daß der Schwerpunkt der Stückgüter ungefähr in der Mitte des Förderbandes liegt. Die seitlichen Anschläge erfassen die Stückgüter zumindest im Bereich der anderen Diagonale. Dieser Bereich überdeckt ebenfalls den Schwerpunkt des Stückgutes, so daß dieses während des Abklappens des Förderbandes sicher zurückgehalten wird.The diagonal trigger ensures that too piece goods of different sizes safely captured by the conveyor belt become. This is arranged so that the focus the piece goods are approximately in the middle of the conveyor belt. The side stops capture the piece goods at least in the Area of the other diagonal. This area covers also the focus of the piece goods, so that this held securely while the conveyor belt is being folded down becomes.

    Außerdem wird durch die diagonale Lage der Stückgüter erreicht, daß das Stückgut entlang zweier rückseitiger Kanten am schmalen Anschlag aufliegen und sicher gehalten werden können, ohne daß die Wegstrecke bis zum Verlassen des Anschlagbereichs zu groß wird.In addition, the diagonal position of the general cargo achieved that the piece goods along two rear edges lie on the narrow stop and be held securely can, without the distance to leave the Stop area becomes too large.

    Die Abzieheinrichtung kann z.B. als Abziehtrommel ausgebildet sein, bei der das Abziehorgan von einer umlaufenden Saugwalze gebildet ist. Die Abzieheinrichtung kann z.B. federnd nachgiebig gelagert sein und mittels eines entsprechend gesteuerten Antriebes in der Stapelrichtung bewegt werden.The puller can e.g. designed as a peeling drum be, in which the puller from a rotating suction roll is formed. The puller can e.g. springy be resilient and stored accordingly controlled drive can be moved in the stacking direction.

    Das Stapelmagazin kann nach Anspruch 2 eine schräge Stapelrichtung aufweisen, die gegen die Abziehrichtung derart geneigt ist, daß die Nachrutschgeschwindigkeit der Stückgüter auf eine geeignete Größe eingestellt werden. Die Neigung erleichtert durch die Schwerkraftwirkung das Ausrichten der zur Abziehrichtung rückseitigen Kanten der Stückgüter an den entsprechenden Seitenwänden des Stapelmagazins. Insbesondere gemischte Stückgüter unterschiedlichen Formats werden somit definiert im Stapel nachgeführt und von den Anschlagflächen erfaßt. Die Neigung des Stapelmagazins kann so gering gehalten werden, daß das Postgut in ergonomisch günstiger Weise eingelegt werden kann.The stack magazine can be inclined according to claim 2 Have stacking direction that against the pulling direction is inclined that the slipping speed of the piece goods be set to an appropriate size. The inclination facilitates the alignment of the by the force of gravity for pulling back edges of the piece goods on the corresponding side walls of the stacking magazine. In particular mixed general cargo of different formats defined in the stack and tracked by the stop surfaces detected. The inclination of the stacking magazine can be so slight be kept that the postal matter in ergonomically more favorable Way can be inserted.

    Die Neigung des Stapelmagazins ergibt eine nach oben weisende Abziehrichtung, die die Wirkung der Schwerkraft zur Verbesserung des Abziehvorganges nutzt. Außerdem ist es möglich, das Magazin entsprechend tiefer zu legen, so daß es manuell leichter nachgefüllt und bedient werden kann.The inclination of the stacking magazine results in an upward-pointing one Pulling direction that affects the effect of gravity Improves the peeling process. Besides, it is possible to lower the magazine accordingly, so that it can be refilled and operated manually more easily.

    Durch die impulsartige Bewegung nach den Ansprüchen 3 können zumindest die untersten Stückgüter nach oben bewegt bzw. komprimiert werden. Im oberen Todpunkt der Bewegung wird das Abziehorgan in der Abziehrichtung betätigt und gleichzeitig nach unten bewegt. Gleichzeitig wird z.B. das Abziehorgan an eine Saugluftquelle angeschlossen, wodurch das unterste Stückgut angesaugt und in Bewegung gesetzt wird, bevor die anderen Stückgüter nachrutschen können.Due to the pulse-like movement according to claims 3 at least the lowest piece goods are moved up or be compressed. At the top dead center of the movement it becomes Puller actuated in the pulling direction and at the same time moved down. At the same time, e.g. the puller a suction air source connected, making the lowest General cargo is sucked in and set in motion before the other general cargo.

    Das Förderband nach Anspruch 4 weist eine ebene Auflagefläche auf, die das Herausziehen des Stückguts und die definierte Ausrichtung auf die Anschlagflächen erleichtert.The conveyor belt according to claim 4 has a flat contact surface on that the pulling out of the piece goods and the defined Alignment to the stop surfaces easier.

    Durch das bewegliche Abziehorgan nach Anspruch 5 läßt sich der Entlastungsimpuls auf den Stapel großflächig ausüben, wobei das Stückgut nur wenig deformiert wird. Das Abziehorgan bleibt während der Bewegung stets mit untersten Stückgut in Kontakt, sodaß die Abziehbewegung unmittelbar bereits bei Erreichen des oberen Totpunktes einsetzen kann. Die Bewegung des Abziehorgans kann in einfacher Weise durch eine Bewegung der gesamten Abzieheinrichtung erzeugt werdenBy the movable puller according to claim 5 can exert the relief impulse on the stack over a large area, whereby the general cargo is only slightly deformed. The puller always stays in with the lowest general cargo during the movement Contact, so that the pulling movement is already at Can reach top dead center. The movement the puller can easily be moved the entire puller are generated

    Die schwenkbare Bewegung des umlaufenden Förderbandes nach Anspruch 6 läßt sich besonders einfach und genau erzeugen. Die Umlenkrolle kann dabei als Antriebsrolle dienen, wodurch das Ankoppeln des Antriebsmotors für das Förderband erleichtert wird.The pivoting movement of the rotating conveyor belt after Claim 6 can be generated particularly easily and precisely. The deflection roller can serve as a drive roller, whereby the coupling of the drive motor for the conveyor belt is facilitated.

    Durch die Anordnung nach Anspruch 7 wird beim Schwenken des Förderbandes vom Stapel weg die Abziehseite besonders weit geöffnet, so daß das Stückgut frei herausgeführt werden kann.By the arrangement according to claim 7 when pivoting the Conveyor belt away from the stack, the pull side particularly far opened so that the general cargo can be freely led out.

    Die Anschläge nach Anspruch 8 ermöglichen es, das Förderband soweit vom Magazin wegzuschwenken, daß das herauszuziehende Stückgut vom nachfolgenden nicht mehr erreicht werden kann. Die Schwenkbewegung kann soweit fortgesetzt werden, daß ein geeigneter Transportwinkel zum Übergeben des Stückgutes z.B. an ein Folgeband eingestellt werden kann. Insbesondere ist es durch die weitwinkelige Klappbarkeit möglich, die Neigung des Magazines von den Bedingungen der Übergabe zu entkoppeln und auf optimale Nachrutsch- und Anschlagbedingungen einzustellen. Die das gewünschte Bewegungsprofil des Linearförderers lassen sich in einfacher Weise mittels einer Kurvenscheibe erzeugen.The stops according to claim 8 allow the conveyor belt to swing away from the magazine as far as that to be pulled out General cargo from the following can no longer be reached. The pivoting movement can be continued so far that a suitable transport angle for transferring the piece goods e.g. can be set to a subsequent tape. In particular it is possible due to the wide-angle foldability, the inclination of the Decouple magazines from the conditions of the handover and for optimal sliding and stop conditions adjust. The desired movement profile of the Linear conveyor can be easily by means of a Generate cam.

    Durch die Weiterbildung nach Anspruch 9 kann der Bewegungsimpuls in einfacher Weise erzeugt werden. Die dem Stückgut zugewandte Oberseite des Anschlags ist zwischen einem Höhenniveau oberhalb und unterhalb der Auflagefläche des Abziehorgans bewegbar, so daß das Stückgut entweder voll auf dem Abziehorgan aufliegen oder gegenüber diesem zurückgehalten werden kann.Through the training according to claim 9 Movement impulse can be generated in a simple manner. The one General cargo facing top of the stop is between a height level above and below the contact surface the puller movable, so that the general cargo is either full lie on or against the puller can be withheld.

    Durch die Weiterbildung nach Anspruch 10 kann der Bewegungsimpuls mit geringem Kraftaufwand erzeugt werden, da hier der Stapel nicht angehoben werden muß.Through the training according to claim 10, the Motion impulse can be generated with little effort, because here the stack does not have to be raised.

    Der Abziehwinkel des Bandtransportes verläuft nach Anspruch 11 stumpfwinkelig schräg zur Stapelrichtung, um einem günstigen Winkel für die Übergabe an ein anderes Transportmittel zu ermöglichen. Das Postgut wird dann im Stapel entsprechend schräg zur Stapelrichtung geneigt stehen, so daß der Winkel zwischen den beiden Führungswänden größer als 90° gehalten werden muß. Die Stapelrichtung kann entsprechend flach gehalten werden, was das manuelle Einlegen von Teilstapeln des Stückgutes erleichtert.The pull-off angle of the belt transport runs according to claim 11 obtuse at an angle to the stacking direction to one convenient angle for transfer to another To enable means of transport. The mail is then in the The stack is inclined at an angle to the stack direction, so that the angle between the two guide walls is larger must be kept as 90 °. The stacking direction can be kept flat accordingly, which is manual loading relieved by partial stacks of the piece goods.

The cam 11 acts on the pivot lever 10 in this way a that this together with the linear conveyor 4 in different angular positions can be pivoted. Reference numerals II, III and IV mark the sections the cam track of the cam plate 11 with the pivot lever 10 are engaged according to Figures 2, 3 and 4.

    Die in der Figur 1 gezeigten Pfeile zeigen die verschiedenen Bewegungsrichtungen der einzelnen Elemente. Durch Verdrehen der Kurvenscheibe 11 wird der Linearförderer 4 entsprechend dem linken oberen Schwenkpfeil zum Stückgut hin geschwenkt.The arrows shown in Figure 1 show the different Direction of movement of the individual elements. By twisting the cam 11, the linear conveyor 4 is corresponding the upper left swivel arrow is swiveled towards the piece goods.

    Diese Stellung ist in Figur 2 dargestellt. Die Schwenkbewegung des Linearförderers ist dabei so heftig, daß das z.B. briefartige Stückgut im unteren Stapelbereich zusammengedrückt wird. Unmittelbar darauf wird der Linearförderer 4 bis über seine Ausgangsstellung hinaus in die in Figur 3 gezeigte Stellung zurückgeschwenkt. Dabei wird das unterste Stückgut z.B. durch im Förderband 3 vorhandene Saugöffnungen mitgenommen. Dabei ist die von der Vertikalen abweichende Neigung des Stapelmagazines 2 so gewählt, daß das darüberliegende Stückgut 1 langsamer nachrutscht, als der Linearförderer 4 weggeschwenkt wird. Das unterste Stückgut 1 kann somit ohne den Druck des restlichen Stapels in der Förderrichtung aus dem Stapelbereich zumindest um eine kurze Strecke herausgeführt werden. This position is shown in Figure 2. The Swiveling movement of the linear conveyor is so violent that that e.g. letter-like piece goods in the lower stack area is squeezed. Immediately afterwards the Linear conveyor 4 in beyond its initial position the position shown in Figure 3 pivoted back. Doing so the bottom general cargo e.g. by existing in the conveyor belt 3 Suction openings taken. Here is the vertical deviating inclination of the stack magazine 2 chosen so that the General cargo 1 slips down more slowly than the Linear conveyor 4 is pivoted away. The lowest general cargo 1 can therefore without the pressure of the rest of the stack in the Direction of conveyance from the stack area at least a short Route be led out.

    Danach wird der Linearförderer 4 mit einem großen Schwenkwinkel in die in Figur 4 gezeigte Stellung geschwenkt, um das herausgeführte Stückgut 1 in eine geeignete Übergabestellung z.B. zu einem nachfolgenden Förderer zu bringen. An der Unterseite des Stapelmagazines 2 ist ein in den Stapelbereich hineinragender Anschlag 13 angebracht, der ein Herausfallen des Stückgutes 1 aus dem Stapelmagazin 2 verhindert.Then the linear conveyor 4 with a large Pivoting angle pivoted into the position shown in Figure 4, in order to take out the general cargo 1 into a suitable one Delivery position e.g. to a subsequent sponsor bring. At the bottom of the stack magazine 2 is an in attached to the stack area protruding stop 13, the the piece goods 1 falling out of the stack magazine 2 prevented.

    In Figur 5 ist erkennbar, daß das wannenartige Stapelmagazin 2 zwei senkrecht zueinander stehende Seitenwände aufweist, die ein L-förmiges Führungsprofil 14 für die Stückgüter 1 bilden, sodaß dieses an den beiden Seitenwänden des Führungsprofiles 14 durch die Schwerkraftwirkung anliegt. Die Winkelstellung des Führungsprofiles 14 zum Förderband 3 ist so gewählt, daß dessen mittlere Spur im Bereich der Diagonalen des briefartigen Stückgutes 1 liegt. Dabei ist durch die definierten Anlage am Führungsprofil 14 sichergestellt, daß auch Stückgut 1 unterschiedlichen Formates vom Förderband 3 sicher erfaßt wird.In Figure 5 it can be seen that the trough-like stack magazine 2 has two mutually perpendicular side walls, an L-shaped guide profile 14 for the piece goods 1 form, so that this on the two side walls of the Guide profile 14 is due to the action of gravity. The Angular position of the guide profile 14 to the conveyor belt 3 is chosen so that its middle track in the range of Diagonals of the letter-like piece goods 1 lies. It is through the defined system on the guide profile 14 ensures that general cargo 1 different Formats from the conveyor belt 3 is detected safely.

    Dieses ist schmaler als die Länge der Diagonale des kleinsten zu vereinzelnden Stückgutes 1. Der stegartige Anschlag 13 erstreckt sich zu beiden Seiten des Förderbandes 3 entlang der unteren Kanten des Führungsprofiles 14. Sie ragen in den Stapelbereich derart hinein, daß selbst das kleinste Stückgut 1 an seinen über das Förderband 3 hinausragenden Ecken im Schwerpunktbereich überdeckt wird und sicher solange anliegt, bis der Linearförderer 4 wieder in seine in Figur 1 gezeigte Ausgangsstellung zurückgeschwenkt worden ist.This is narrower than the length of the smallest diagonal to be separated piece goods 1. The web-like stop 13 extends along both sides of the conveyor belt 3 the lower edges of the guide profile 14. They protrude into the Stacking area in such a way that even the smallest piece goods 1 at its corners protruding beyond the conveyor belt 3 in The focus area is covered and is safe as long as until the linear conveyor 4 returns to that shown in FIG Starting position has been pivoted back.

    In Figur 6 ist ferner an das Stapelmagazin 2 ein Impulsgeber 15 angesetzt, der auf die Seitenwände und somit auf den Stapel gemäß dem Doppelpfeil quer zur Stapelrichtung stoßartige Impulse ausgibt. Diese können z.B. temporär zu Beginn des Abziehvorganges oder auch permanent in der Art von Vibratoren erzeugt werden. Dadurch werden die unterschiedlich großen Stückgüter 1 an den Seitenwänden sicher ausgerichtet, so daß sie mit zwei aneinandergrenzenden Seiten an den Seitenwänden definiert anliegen. Die Impulse des Impulsgebers (15) verringern außerdem die Haftreibung zwischen den Stückgütern 1 und erleichtern somit das Abziehen des untersten Stückgutes 1 durch das Förderband 3.In FIG. 6 there is also a pulse generator on the stack magazine 2 15 set on the side walls and thus on the Stack according to the double arrow across the stack direction gives impulses. These can e.g. temporarily too Start of the peeling process or permanently in the manner of Vibrators are generated. This makes them different large piece goods 1 are safely aligned on the side walls, so that they have two adjacent sides on the Side walls are defined. The impulses of the pulse generator (15) also reduce static friction between the General cargo 1 and thus make it easier to pull off the lowest piece goods 1 through the conveyor belt 3.

    Das Stapelmagazin 2 ist hier in einem sehr flachen Neigungswinkel angeordnet, der das manuelle Einlegen von Teilstapeln der Stückgüter 1 in niedriger Bedienlage ergonomisch erheblich begünstigt. Die Ausgangsstellung des Förderbandes 3 ist stumpfwinkelig zur Stapelrichtung geneigt, was die Weitergabe der Stückgüter 1 begünstigt. Diese stehen damit nicht senkrecht, sondern entsprechend schräg zur Stapelrichtung. Um die Seitenwände des Stapelmagazins 2 an die Schräglage der Stückgüter anzupassen, stehen die Seitenwände in einem Winkel von mehr als 90° zueinander. Der als Vibrator ausgebildete Impulsgeber 15 ermöglicht trotz des geringen Neigungswinkels des Stapels ein sicheres Nachrutschen des Stückgutes.The stacking magazine 2 is here in a very flat one Tilt angle arranged, the manual insertion of Partial stacking of piece goods 1 in a low operating position ergonomically favored. The starting position of the Conveyor belt 3 is inclined at an obtuse angle to the stacking direction, which favors the forwarding of general cargo 1. These stand therefore not perpendicular, but rather obliquely to Stacking direction. Around the side walls of the stacking magazine 2 to adjust the inclined position of the general cargo Side walls at an angle of more than 90 ° to each other. The trained as a vibrator pulse generator 15 allows despite the low angle of inclination of the stack a safe Slipping of the general cargo.

    Nach den Figuren 7 und 8 ist das Förderband 3 feststehend ausgebildet und ist der Anschlag 13 nicht am Führungsprofil 14, sondern an einem Schwinghebel 17 befestigt, der durch einen anderen Schwenkantrieb 18 um seine Schwenkachse 8 derart schwenkbar ist, daß die Anschläge 13 impulsartig gegen die gestapelten Stückgüter gedrückt und von diesem weg bewegt werden können. Dabei werden die Anschläge 13 kurzfristig auf ein unterhalb des Förderbandes 3 liegendes Niveau solange abgesenkt, bis das jeweilige Stückgut 1 den Auflagebereich der Anschläge 13 verlassen hat. Unmittelbar darauf werden diese in ihre Ausgangslage oberhalb des Bandniveaus zurückbewegt, so daß das nachfolgende Stückgut 1 zurückgehalten wird.According to Figures 7 and 8, the conveyor belt 3 is fixed trained and the stop 13 is not on the guide profile 14, but attached to a rocker arm 17, which by another swivel drive 18 about its swivel axis 8 is pivotable in such a way that the stops 13 counterpulse the stacked piece goods are pressed and moved away from it can be. The stops 13 are briefly on a level below the conveyor belt 3 as long lowered until the respective general cargo 1 reaches the support area the stops 13 has left. Be immediately on it these in their starting position above the band level moved back so that the following general cargo 1 is held back.
