Abstract

The invention relates to a device for stacking flat, flexible, postal items in a stacking compartment, comprising a stacking roller (8), in an upright position. A profile roller (1) having several diameter taperings arranged over the length of the roller are arranged on the axis (10) and above the deflection roller (11) of the short strip (4) of a cover strip system (4,5). Deflectable pressing means, which press the postal items into the taperings of the profile roller (1) by means of spring force, is arranged on the profile roller. As a result, the free flexible lengths of the flexible postal items (3), in particular the sheets of open magazines, are reduced.

Description

Beschreibungdescription
Vorrichtung zum Einstapeln flacher, biegsamer Sendungen in ein StapelfachDevice for stacking flat, flexible items in a stacking compartment
Die Erfindung betrifft eine Vorrichtung zum Einstapeln flacher, biegsamer Sendungen in ein Stapelfach nach dem Oberbegriff des Anspruches 1. Solche Stapelfächer sind beispielsweise Bestandteile von Sor- tierfachstrecken in Sendungssortieranlagen. Über eine Transportstrecke mit Weichen werden die Sendungen entsprechend den Zieladressen auf die zugeordneten Stapelfächer verteilt. Um einen hohen Durchsatz der Sendungssortieranlagen zu erreichen, werden die Abstände zwischen den Sendungen (Sendungslü- cken) möglichst klein gewählt. Sollen unterschiedliche Sendungsarten (z.B. dünne instabile hohe Sendungen, offene Zeitschriften) eingestapelt werden, so sind sie in einen solchen Zustand zu versetzen, dass sie den weitgehend stützfreien Weg zwischen der letzten Klemmstelle der Transportstrecke und der Stapelrolle passieren, ohne dass dabei die offenen Sendungen durch den Fahrtwind aufgeblättert werden und dadurch beim Einstapeln gefaltet oder beschädigt werden. Weiterhin sollen die hohen instabilen Sendungen so stabilisiert werden, dass sie mit den schon eingestapelten Sendungen nicht kollidieren.The invention relates to a device for stacking flat, flexible mail items into a stacking compartment according to the preamble of claim 1. Such stacking compartments are, for example, components of sorting bin sections in mail sorting systems. The consignments are distributed to the assigned stacking compartments according to the destination addresses via a transport route with switches. In order to achieve a high throughput of the mail sorting systems, the distances between the mail items (mail gap) are chosen to be as small as possible. If different types of consignments (e.g. thin, unstable, high consignments, open magazines) are to be stacked, they must be set in such a state that they pass the largely unsupported path between the last nip point of the transport route and the stacking roll, without the open consignments passing through the airstream is blown off and thereby folded or damaged during stacking. Furthermore, the high unstable mail items should be stabilized so that they do not collide with the mail items already stacked.
Im Stand der Technik wird eine Stapeleinrichtung beschrieben (EP 0 127 067 AI) , die als Umlenkrolle des kürzeren Deckbandes eine sogenannte Wulstrolle besitzt. Diese Wulstrolle, die länger als die Deckbandbreite ist, hat an ihren Enden jeweils eine Wulst. Da das weiterlaufende Band des Deckbandsystems die Sendung gegen die Wulstrolle in ihrer Mitte drückt und die äußeren Sendungsteile dabei an die Wülste anlegen, wird eine biegsame Sendung durchgebogen und damit stabilisiert, sodass sie sich auf dem einseitig geführten Weg in das Sta- pelfach nicht verformt. Hiermit kann also nur für eine labile Sendung geringer Höhe eine Längsversteifung zur Stabilisie- rung erzielt werden. Hohe instabile und offene Sendungen können damit nicht sicher und störungsfrei eingestapelt werden.In the prior art, a stacking device is described (EP 0 127 067 AI), which has a so-called bead roller as the deflection roller of the shorter shroud. This bead roll, which is longer than the cover band width, has a bead at each end. Since the continuous belt of the shroud system presses the mailing against the bead roll in the middle and the outer parts of the mailing lie against the beads, a flexible mailing is bent and thus stabilized so that it does not deform on the one-sided path into the stacking compartment. This means that a longitudinal stiffening for stabilization can only be tion can be achieved. This means that high, unstable and open consignments cannot be stacked safely and without interference.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Einstapeln flacher, biegsamer Sendungen in ein Stapelfach in stehender Position zu schaffen, mit der offene, einseitig gebundene Sendungen, wie Zeitschriften, einseitig geführt sicher und störungsarm eingestapelt werden, ohne dass sie durch den Fahrtwind aufgeblättert werden.The invention has for its object to provide a device for stacking flat, flexible mail items in a stacking position in the standing position, with the open, one-sided bound items, such as magazines, are stacked securely and with little disruption on one side without being blown up by the wind become.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruches 1 gelöst .According to the invention the object is achieved by the features of claim 1.
Auf der Achse und oberhalb der Umlenkrolle des kürzeren Bandes des Deckbandsystems befindet sich eine Profilrolle mit mehreren Durchmesserverjüngungen über seine Rollenlänge. An der Profilrolle ist ein die Sendungen in die Verjüngungen der Profilrolle mit Federkraft drückendes, auslenkbares Andruck- mittel angeordnet, wodurch den biegsamen Sendungen ein versteifendes mehrwelliges Profil eingeprägt wird. Damit die Sendungsoberkanten der Sendungen mit den zugelassenen Sendungsformaten nicht über ein festgelegtes Höchstmaß über die höchste von der jeweiligen Sendung überdeckte Verjüngung hinausragen, werden die Verjüngungen der Profilrolle dementsprechend über die Rollenlänge verteilt. Dadurch wird die freie Biegelänge der biegeweichen Einzel- blätter von z.B. offenen Zeitschriften so verkürzt, dass sie durch den während des Einstapeins wirkenden Luftwiderstand nicht aufgeblättert werden. Die Gefahr des Aufblätterns betrifft vor allem die in Transportrichtung oberen Ecken der Blätter.On the axis and above the deflection roller of the shorter band of the shroud system there is a profile roller with several tapered diameters over its length. A deflectable pressure means, which presses the mailings into the tapering of the profile roll with spring force, is arranged on the profile roll, as a result of which a stiffening multi-shaft profile is impressed on the flexible mailings. So that the top edges of the consignment with the approved consignment formats do not protrude beyond a specified maximum dimension beyond the highest taper covered by the consignment in question, the tapering of the profile roll is distributed over the roll length accordingly. The free bending length of the flexible single sheets of e.g. open journals shortened so that they are not flipped open by the air resistance acting during insertion. The danger of opening up particularly affects the upper corners of the leaves in the direction of transport.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen dargelegt . So ist es vorteilhaft, als Andruckmittel schmale, auslenkba- re, an die Verjüngungen der Profilrolle mit den geringerenAdvantageous embodiments of the invention are set out in the subclaims. So it is advantageous as a pressure medium narrow, deflectable, to the taper of the profile roller with the smaller ones
Durchmessern mittels Federkraft drückende Andruckrollen vorzusehen. In einer weiteren Ausführungsform des Andruckmitteis kann eine zweite Profilrolle mit gleichem Profil so angeordnet werden, dass sich die Durchmesserverjüngungen der einen Profil- rolle auf der Höhe der unverjungten Abschnitte der anderen Profilrolle befinden.Diameters of pressure rollers to be pressed using spring force. In a further embodiment of the pressure medium, a second profile roller with the same profile can be arranged in such a way that the tapered diameters of one profile roller are at the level of the untapered sections of the other profile roller.
Vorteilhaft ist es auch, die Andruckkraft des Andruckmitteis nur so groß zu wählen, dass steifere Sendungen nicht durch gewaltsame Verformung beschädigt werden.It is also advantageous to select the pressure force of the pressure medium only so large that stiffer mail items are not damaged by violent deformation.
Anschließend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnung erläutert.The invention is then explained in an exemplary embodiment with reference to the drawing.
Dabei zeigen FIG 1 eine schematische Draufsicht auf die Einstapelvorrichtung und das Stapelfach,1 shows a schematic top view of the stacking device and the stacking compartment,
FIG 2 eine Seitenansicht einer Profilrolle mit zwei Andruckrollen.2 shows a side view of a profile roller with two pressure rollers.
Der Übersicht halber ist in FIG 1 das Stapelfach nicht vollständig dargestellt, sondern nur mit seinen zur Erläuterung der Funktion benötigten Komponenten. Die flachen Sendungen 3 werden dem Stapelfach in aufrechter Position, zwischen zwei relativ schmalen, angetriebenen Bändern 4,5 eines Deckbandsystems eingeklemmt, schräg zugeführt. Am Eingang des Stapel - faches wird das auf der Stapelseite liegende Band 4 über eine Umlenkrolle 10 zurückgeführt, damit die einzustapelnde Sendung 3 an dieser Seite frei ist und eingestapelt werden kann. Die Sendung 3 wird dann einseitig von dem anderen Band 5 bis zu einer Stapelrolle 8 geleitet . An dieser Stapelrolle 8 wird die in einem Winkel zur Stapelausrichtung einlaufende Sendung 3 in eine parallele Ausrichtung zu den eingestapelten Sendungen des Stapels 9 umgebogen und bis zu einer Anschlag- wand 12 transportiert. Mit jeder neu eingestapelten Sendung 3 wird eine den Stapel 9 haltende Stapelstütze 13 von der Sta- pelrolle 8 weg verfahren, sodass wieder Platz für eine neue Sendung 3 geschaffen wird.For the sake of clarity, the stacking compartment is not shown completely in FIG. 1, but only with its components required to explain the function. The flat mail items 3 are fed obliquely to the stacking compartment in an upright position, clamped between two relatively narrow, driven belts 4, 5 of a shroud system. At the entrance of the stacking compartment, the band 4 lying on the stack side is returned via a deflection roller 10, so that the item 3 to be stacked is free on this side and can be stacked. The shipment 3 is then passed on one side from the other belt 5 to a stacking roll 8. On this stacking roller 8, the mail item 3 arriving at an angle to the stack alignment is bent into a parallel alignment to the stacked mail items of the stack 9 and transported up to a stop wall 12. With each newly stacked shipment 3, a stack support 13 holding the stack 9 is removed from the stack. Move the roller 8 away so that space for a new shipment 3 is created again.
Auf dem Wege zur Stapelrolle 8 können offene, einseitig gebundene, mehrblättrige Sendungen, z.B. offene Zeitschriften, mit nur geringer Eigensteifigkeit bei relativ hohen Einstapelgeschwindigkeiten infolge des Luftwiderstandes beim Einstapeln mit der gebundenen Seite nach unten aufgeblättert werden. Um die freien Biegelängen der Zeitschriften unterschiedlicher Formate zur Verhinderung des Aufblätterns zu re- duzieren, erhalten die Sendungen 3 bei genügender Elastizität mittels einer auf der Achse 10 der Umlenkrolle 11 und über ihr befindliche Profilrolle 1 (was bei den offenen Zeitschriften gegeben ist) Querschnittsprofile. Die an sich bekannte Umlenkrolle 11 besitzt unten eine Wulst, damit die durch das Band 5 des Deckbandsystems an die Umlenkrolle 11 angedrückte Sendung 3 im unteren Teil von der Umlenkrolle 11 weg durchgebogen wird. Da hiermit die großen Sendungen 3 keine Stabilität erhalten, befindet sich über der Umlenkrolle 11 die Profilrolle 1 mit dem wellenförmig verjüngten Profil. Da- mit die Sendungen 3 über ihre Höhe diesen Profilverlauf annehmen, müssen sie zumindest an die verjüngten Bereiche der Profilrolle 1 angedrückt werden.On the way to the stacking roll 8, open, single-sided, multi-sheet items, e.g. open magazines, with little inherent rigidity at relatively high stacking speeds due to the air resistance when stacking with the bound side down. In order to reduce the free bending lengths of the magazines of different formats to prevent them from being opened, the mail items 3 are provided with cross-sectional profiles with sufficient elasticity by means of a profile roller 1 located on the axis 10 of the deflecting roller 11 and above it (which is the case with open magazines). The known deflection roller 11 has a bead at the bottom so that the mail item 3 pressed against the deflection roller 11 by the band 5 of the shroud system is deflected away from the deflection roller 11 in the lower part. Since the large consignments 3 are hereby not given stability, the profile roller 1 with the wavy tapered profile is located above the deflection roller 11. So that the mail items 3 assume this profile profile over their height, they must at least be pressed against the tapered areas of the profile roller 1.
Dies geschieht hier, indem an der Profilrolle 1 in der Höhe dieser verjüngten Bereiche schmale Andruckrollen 7 drehbar auf einem Schwenkarm 2 gelagert sind und mittels einer an denThis is done here by narrow pressure rollers 7 are rotatably mounted on a swivel arm 2 on the profile roller 1 at the height of these tapered areas and by means of a to the
Schwenkarm 2 angreifenden Feder 6 gegen die Profilrolle 1 gedrückt werden. Dadurch erhalten die Sendungen 3 dieses Profil . Dieses Andrücken kann auch erfolgen, indem es mit einer profilierten Andruckrolle geschieht, wobei sich die Verjün- gungen dieser Andruckrolle in Höhe der Bereiche mit den größeren Durchmessern der Profilrolle 1 befinden. Wieviel Verjüngungen die Profilrolle 1 besitzt und an welchen Stellen über die Rollenlänge verteilt diese sich befinden, hängt auch von dem zu verarbeitenden Sendungsformatspektrum ab. Da sich herausgestellt hat, dass die Gefahr des Aufblätterns von offenen, einseitig gebundenen Sendungen 3 (Bindekante befindet sich unten) vor allem bei den in Transport- -cichtung vorderen oberen Ecken besteht, ist der Wellenabstand im oberen Bereich der Sendungen 3 des Sendungsformatspektrums so gewählt, dass die resultierend maximale freie Biegelänge so gering ist, dass auf dem Weg zur 'Stapelrolle 8 ein Aufblättern nicht auftritt. Der Wellenabstand muss also über die Höhe/Länge der Profilrolle 1 nicht gleich sein. Swing arm 2 engaging spring 6 are pressed against the profile roller 1. As a result, the shipments 3 receive this profile. This pressing can also take place by using a profiled pressure roller, the tapering of this pressure roller being at the level of the regions with the larger diameters of the profile roller 1. How many tapering the profile roll 1 has and at which points over the roll length these are located also depends on the range of mailing formats to be processed. Since it has been found that the risk of the open items 1 being bound on one side being bound (binding edge is at the bottom), especially in the -c direction front upper corners, the shaft spacing in the upper area of the mail items 3 of the mail item format spectrum is selected such that the resulting maximum free bending length is so small that there is no flaring on the way to the 'stacking roll 8'. The shaft distance does not have to be the same over the height / length of the profile roller 1.
