Description

Einrichtung zur Vereinzelung von stapel¬ weise zugeführten flachen GegenständenDevice for separating stacked flat objects
Die Erfindung betrifft eine Einrichtung zur Vereinzelung von auf einem umlaufenden Transportmittel stapelweise, stehend zugeführten, flachen Gegenständen wie Umschlägen, Briefen, Taschen, Beutel, Druckbogen oder dgl., bestehend aus einer die Gegenstände flachseitig mittels einem Trum eines umlaufenden Förderorgans von dem vorderen Stapelende einzeln erfassenden und quer zur Stapelbildungsrichtung abtragenden Fördervorrich¬ tung.The invention relates to a device for separating flat objects, such as envelopes, letters, bags, pouches, printed sheets or the like, which are stacked upright and stacked on a rotating means of transport, consisting of one of the objects on the flat side by means of a strand of a rotating conveyor element from the front end of the stack individually conveying device which detects and transversely to the stack formation direction.
Eine Einrichtung dieser Art vermitteln u.a. die EP - A - 0 191 351, 0 215 469, 0 423 664, 0 525 582 und 0 589 789. Bei der EP - A - 0 191 351 handelt es sich um einen Verein¬ zeier flacher Gegenstände mit unterschiedlichen physikalischen Merkmalen, die über ein breites Spektrum streuen, wobei eine Zuführstation für einen Stapel der Gegenstände und eine Ab¬ führstation für die vereinzelten Gegenstände vorgesehen ist. Dazwischen ist eine Vereinzelungsstation angeordnet, welche die Gegenstände an dem vorderen Stapelende erfasst und in Querrichtung an die Abführstation versetzt. Zu diesem Zweck sieht die genannte Druckschrift vor, dass die senkrecht zur Vereinzelungsrichtung gebildeten Stapel mittels seitlich ein¬ schwenkbaren Fingern oder Mitnehmern an die Vereinzelungssta¬ tion verschoben werden, wo der vorderste Gegenstand im Fuss- bereich an einen niedrigen Anschlag stösst. Mit einer oszil¬ lierend angetriebenen, auf den vordersten Gegenstand angesetz¬ ten Ansaugvorrichtung wird seine Versetzung an die seitlich stationierte Abführstation durchgeführt. Diese besteht aus einem mit Durchtrittsöffnungen versehenen, endlos umlaufenden Förderband, hinter welchem an der Flugbhan der abgeführten Gegenstände eine Vakuumkammer angeordnet ist, die mit den Durchtrittsöffnungen des Förderbandes zusammenwirkend den ge¬ genüberliegenden Gegenstand am Förderband hält.A device of this type is conveyed inter alia by EP-A-0 191 351, 0 215 469, 0 423 664, 0 525 582 and 0 589 789. EP-A-0 191 351 is a display of flat objects with different physical features that scatter over a broad spectrum, a feed station for a stack of the articles and a discharge station for the individual articles being provided. A separating station is arranged in between, which detects the objects at the front end of the stack and into them Moved transversely to the discharge station. For this purpose, the cited document provides that the stacks formed perpendicular to the singling direction are moved to the singling station by means of fingers or catches which can be swiveled in laterally, where the foremost object hits a low stop in the foot region. With an oscillating driven suction device attached to the foremost object, it is moved to the discharge station stationed on the side. This consists of an endlessly revolving conveyor belt provided with passage openings, behind which a vacuum chamber is arranged on the flight path of the objects being removed, which, in cooperation with the passage openings of the conveyor belt, holds the opposite object on the conveyor belt.
Bei der EP - A - 0 215 469 geht es um eine Anlage zur Markie¬ rung von flachen Gegenständen, insbesondere Postsendungen, die kodierte Angaben auf die flachen Gegenstände gemäss den auf den Gegenständen vermerkten Adressangaben schreibt und zu die¬ sem Zweck mit einer manuellen Kodierstation ausgestattet ist. Dieser Anlage ist auch eine Vereinzelungseinrichtung zu¬ geschaltet, mit der die gestapelt ankommenden Gegenstände an dem vorderen Ende mit einem evakuierbaren Förderorgan - Trom¬ mel oder Band - vom Stapel entnommen und seitlich in eine För¬ dervorrichtung verschoben werden. Allerdings handelt es sich hier um eine diskontinuierliche Zuführung und Verarbeitung der Stapel, die durch eine angetriebene Rückwand des zu entsorgen¬ den Magazins der Vereinzelungsvorrichtung zugeführt werden, wobei die Rückwand bei entleertem Magazin zum Befüllen wieder in die Ausgangslage zurückversetzt wird.EP-A-0 215 469 is a system for marking flat objects, in particular mail items, which writes coded information on the flat objects in accordance with the address information noted on the objects and for this purpose with a manual coding station Is provided. A separating device is also connected to this system, with which the stacked objects arriving at the front end are removed from the stack with an evacuable conveying element - drum or belt - and laterally shifted into a conveying device. However, this involves discontinuous feeding and processing of the stacks, which are fed to the separating device by a driven rear wall of the magazine to be disposed of, the rear wall being returned to the starting position when the magazine is empty for filling.
Ähnliche Einrichtungen vermitteln die EP - A - 0 525 582 und 0 589 789. Die nach den aufgeführten Druckschriften vorgeschlagenen Ein¬ richtungen nach der eingangs erwähnten Art verfügen nicht über die Vorkehrungen, die einer störungsfreien Verarbeitung der in unterschiedlichen Formaten und Dicken vorkommenden Gegenstände genügen.Similar devices are provided by EP - A - 0 525 582 and 0 589 789. The devices proposed in accordance with the publications mentioned, according to the type mentioned at the outset, do not have the precautions which suffice for trouble-free processing of the objects occurring in different formats and thicknesses.
Es mangelt diesen bekannten Einrichtungen nicht nur an einem zuverlässigen Funktionieren der zusammenhängenden Bewegungen an der Erfassungsstelle der Gegenstände, sondern auch im Be¬ reich der Übergabe von der Vereinzelungsstation zum Weiter¬ transport.These known devices lack not only a reliable functioning of the coherent movements at the detection point of the objects, but also in the area of the transfer from the singling station to further transport.
Aufgabe der vorliegenden Erfindung ist es deshalb, eine Ein¬ richtung der eingangs genannten Art zu schaffen, bei der die Zuverlässigkeit der Verarbeitung und damit die Leistung auf einfache Weise verbessert werden kann.The object of the present invention is therefore to create a device of the type mentioned at the outset in which the reliability of the processing and thus the performance can be improved in a simple manner.
Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass die Fördervorrichtung mittels Führungsanordnung etwa parallel zu der Stapelbildungsrichtung sich an dem vorderen Stapelende des an dem hinteren Ende abgestützen Stapels anlehnend hubartig versetzbar angetrieben ist.According to the invention, this object is achieved in that the conveyor device is driven by means of a guide arrangement, approximately parallel to the stack formation direction, so as to be displaceable in a stroke-like manner, based on the front stack end of the stack supported at the rear end.
Eine solche Ausbildung gestattet eine kontinuierliche Verar¬ beitung von flachen Gegenständen unterschiedlicher Grosse.Such a design permits continuous processing of flat objects of different sizes.
Vorteilhaft sind die hubartigen Bewegungen der Fördervorrich¬ tung durch Anschläge begrenzt, wodurch die Abgabesposition der Gegenstände beeinflussbar ist.The stroke-like movements of the conveying device are advantageously limited by stops, as a result of which the delivery position of the objects can be influenced.
Vorzugsweise ist die Fördervorrichtung an einem antreibbaren Gestell befestigt, das sich als Teil der Führungsanordnung ausbilden lässt.The conveyor device is preferably fastened to a drivable frame which can be formed as part of the guide arrangement.
Das Gestell erweist sich auch als verbindender Bauteil zu ei- ner die Antriebskraft erzeugenden Last als zweckmässig.The frame also proves to be a connecting component to ner the driving force generating load as appropriate.
Zur Begünstigung des Vereinzelungsvorganges ist dem bandförmi¬ gen Förderorgan eine mit letzterem einen Einzugsspalt für die erfassten Gegenstände bildende gleichsinnig drehbare Abstreif¬ rolle zugeordnet, die auch einer Stabilisierung der Gegenstän¬ de während dem Vereinzelungsvorgang zuträglich ist.To favor the separating process, the belt-shaped conveying member is assigned a wiping roller which can be rotated in the same direction and forms a feed gap for the detected objects, and which also helps stabilize the objects during the separating process.
Der Abstreifrolle, die durch die Gegenstände angetrieben wird, ist an dem Zutrittsende des Einzugsspaltes auf der von dem Förderorgan abgewendeten Seite ein stationäres Leitorgan vor¬ geschaltet, das den Einzugsvorgang der Gegenstände unter¬ stützt.The scraper roller, which is driven by the objects, is preceded by a stationary guide element at the entry end of the feed gap on the side facing away from the conveying element, which supports the pulling-in process of the objects.
Dieses Leitorgan kann auch gegenüber der Abstreifrolle zur Veränderung des Einzugsspaltes verstellbar ausgebildet sein.This guide element can also be designed to be adjustable relative to the scraper roller in order to change the feed gap.
Deshalb ist die Abstreifrolle und/oder das Leitorgan zum För¬ derorgan hin und von diesem weg versetzbar und/oder der Ein¬ zugswinkel veränderbar ausgebildet, sodass der Einzugsspalt an die Einzugsbedingungen angepasst werden können.For this reason, the scraper roller and / or the guide member can be displaced towards and away from the conveyor member and / or the feed angle can be changed so that the feed gap can be adapted to the feed conditions.
Die Zustellbewegung der Abstreifrolle und/oder das Leitorgan erfolgt vorteilhaft mit Hilfe eines Kraftspeichers gegen den die genannten Organe durch das Auftreffen eines vom Stapel abgezogenen Gegenstandes zurückweichen.The feed movement of the scraper roller and / or the guide member is advantageously carried out with the aid of a force accumulator against which the above-mentioned organs recede due to the impact of an object pulled off the stack.
Die Bewegungsrichtung der Abstreifrolle zum Förderorgan ist zweckmässig so gewählt, dass sie mit letzterem bzw. dem Trum des Förderorgans einen spitzen Winkel einschliesst, wodurch die durch das Auftreffen der Gegenstände erzeugten Schläge gemildert werden.The direction of movement of the scraper roller relative to the conveying member is expediently chosen such that it encloses an acute angle with the latter or the strand of the conveying member, as a result of which the impacts generated by the impact of the objects are reduced.
Zur Erzielung der Anstellbewegung - in deren einen Endposition die Abstreifrolle wenigstens annähernd an dem Förderorgan an¬ steht - ist vorteilhaft eine Linearführung bzw. Längsführung vorgesehen, welche leicht und genau reagiert.To achieve the positioning movement - in one end position the scraper roller is at least approximately in contact with the conveying member - a linear guide or longitudinal guide is advantageously provided, which reacts easily and precisely.
Hierzu ist die Linearführung durch zwei an einem Support von¬ einander beabstandete parallele Führungselemente ausgebildet, an denen ein die gelagerten Abstreifrollen aufnehmender Lager¬ bock verschiebbar angeordnet ist.For this purpose, the linear guide is formed by two parallel guide elements spaced apart from one another on a support, on which a bearing block that accommodates the mounted stripping rollers is slidably arranged.
Die Anstellkraft der Abstreifrolle gegen das Förderorgan kann dadurch erreicht werden, dass der Kraftspeicher zwischen Sup¬ port und Lagerbock vorgesehen wird, beispielsweise durch eine Druckfeder.The contact force of the scraper roller against the conveyor element can be achieved by providing the energy store between the support and the bearing block, for example by means of a compression spring.
Eine weitgehend störungsfreie Vereinzelung der in einem Stapel transportierten Gegenstände kann dann erzielt werden, wenn das Transportmittel zur Bestimmung der Zuführgeschwindigkeit der Gegenstände in Abhängigkeit zur Hublage der Fördervorrichtung bzw. des Förderorgans mit einer Steuervorrichtung verbunden ist, sodass ein automatischer Regeleffekt bei der Stapelver¬ arbeitung eintritt.A largely trouble-free separation of the objects transported in a stack can be achieved if the transport means for determining the feed speed of the objects is connected to a control device as a function of the stroke position of the conveying device or the conveying member, so that an automatic control effect occurs during stack processing .
Um der Fördervorrichtung ununterbrochen flache Gegenstände Zuführung zu können, ist es zweckmässig, wenn das bandartig ausgebildete Transportmittel mit in Abständen sich folgenden, fest angeordneten, gegenseitig Einsteckfächer bildenden Mit¬ nehmern ausgebildet ist, die im Wirkbereich des zu passieren¬ den Förderorgans eine Ausnehmung aufweisen.In order to be able to continuously feed flat objects to the conveying device, it is expedient if the belt-like transport means is formed with spaced-apart, firmly arranged, mutually inserting compartments which have a recess in the effective area of the conveying member to be passed.
Die Ausnehmungen, die oberhalb des Förderorgans bis an das umlaufende Transportband reichen, wirken sich auf die Befesti¬ gungsmöglichkeiten der Mitnehmer an dem Transportband aus, indem die Mitnehmer durch eine an die Ausnehmung anschliessen- de Befestigungsvorrichtung mit dem Transportmittel verbunden sind.The recesses, which extend above the conveying member to the circulating conveyor belt, have an effect on the fastening options of the drivers on the conveyor belt in that the drivers are connected to the transport means by a fastening device connected to the recess are.
Es empfiehlt sich zudem, dass die durch die Mitnehmer gebilde¬ ten Transportfächer durch eine vor dem Förderorgan endende, eine konstante Anschlagkante für die Gegenstände bildende sta¬ tionäre Wand einseitig geschlossen sind, sodass die abzutra¬ genden Gegenstände jeweils an der gleichen Stelle des Förder¬ organs auftreffen.It is also recommended that the transport compartments formed by the carriers are closed on one side by a stationary wall that ends in front of the conveying element and forms a constant stop edge for the objects, so that the objects to be removed are in each case at the same point on the conveyor organs hit.

Die Fig. 1 und 2 zeigen eine Einrichtung 1 zur Vereinzelung von auf einem umlaufenden Transportmittel 2 stapelweise ste¬ hend zugeführten, flachen Gegenständen 5, wie Postsendungen in Form von Umschlägen, Briefen, Taschen, Beuteln, Druckbogen, Paketen oder dgl. Das Transportmittel 2 weist weiterhin ein endloses Transportband 3 oder nebeneinandergereihte Transport¬ bänder auf, an denen über die förderwirksame Breite sich er¬ streckend und sich in Abständen folgend, Transportfächer 4 für die stapelweise aufgegebenen Gegenstände 5 bildende Mitnehmer 6 befestigt sind. Die Zeichnung zeigt ein mit Gegenständen 5 vollständig besetztes Transportfach 4 hinter einem dem Verein- zelungsprozess unterzogenen Transportfach. An der Seite des Transportmittels 2, unmittelbar von dem Transportband 3 hochragend, ist eine in der Zuführrichtung - Pfeil Z- der Gegenstände 5 angeordnete Wand 7 vorgesehen, die bis an eine anschliessend beschriebene, mit einer Fördervor¬ richtung zusammenwirkende Abstreifrolle 8 reicht, die eine Anschlagkante zur Positionierung der Gegenstände 5 bildet. Die Gegenstände 5 werden durch ein Förderorgan 10 der Förder¬ vorrichtung 9 am vorderen Ende eines zugeführten Stapels 11 erfasst und seitlich abgezogen.1 and 2 show a device 1 for separating flat objects 5, such as mail items in the form of envelopes, letters, bags, pouches, printed sheets, parcels or the like, which are fed in stacks standing on a rotating means of transport 2. The means of transport 2 furthermore has an endless conveyor belt 3 or conveyor belts lined up next to one another, on which conveyor compartments 4 for and extend over the width effective for conveying and follow one another at intervals the stacked objects 5 forming drivers 6 are attached. The drawing shows a transport compartment 4 fully occupied with objects 5 behind a transport compartment which has undergone the separation process. On the side of the means of transport 2, projecting directly from the conveyor belt 3, there is a wall 7 arranged in the feed direction - arrow Z - of the objects 5, which extends to a subsequently described stripping roller 8 which interacts with a conveying device and which has a Stop edge for positioning the objects 5 forms. The objects 5 are grasped by a conveying element 10 of the conveying device 9 at the front end of a supplied stack 11 and are pulled off laterally.
Zu diesem Zweck ist das Förderorgan 10 bzw. die Fördervorrich¬ tung 9 an das vordere Ende des Stapels 11 angelehnt, damit eine zum Abziehen des vorderen Gegenstandes 5 erforderliche Dichtheit mit einer Vakuumquelle 15 entstehen kann, derart, dass eine korrekte Vereinzelung entsteht.For this purpose, the conveying element 10 or the conveying device 9 is leaned against the front end of the stack 11, so that a tightness required for pulling off the front object 5 can be created with a vacuum source 15 in such a way that correct separation occurs.
Bei dem Förderorgan 10 handelt es sich um ein um senkrechte Walzen umlaufend angetriebenes Förderband 12, dessen den durch das Transportmittel 2 zugeführten Gegenständen 5 zugewendetes Trum 13 zwei übereinander angeordnete Ausnehmungen 14 auf¬ weist, die intermittierend mit einer hinter dem Trum 13 an¬ geordneten Vakuumquelle 15 kommunizieren (siehe auch Fig. 3) . Mit gestrichelter Linie 16 ist eine dafür notwendige Vakuum¬ kammer in den Fig. 2 und 3 angedeutet.The conveyor element 10 is a conveyor belt 12 driven around vertical rollers, the strand 13 of which, facing the objects 5 supplied by the transport means 2, has two recesses 14 arranged one above the other, which are intermittent with a vacuum source arranged behind the strand 13 15 communicate (see also Fig. 3). A vacuum chamber necessary for this is indicated by dashed line 16 in FIGS. 2 and 3.
Das Anlehnen des Förderorgans 10 an das vordere Stapelende erfolgt durch einen hubartigen Nachlaufeffekt der Fördervor¬ richtung 9, die hierzu an einem parallel zur Zuführrichtung Z parallel beweglichen Gestell 17 befestigt ist. Letzteres kann sowohl auf Schienen als auch -wie dargestellt- mittels einer Führungsanordnung 18 geführt sein, die aus wenigstens einer FührungsStange 19 und an dieser gleitend verstellbar geführ¬ ten, das Gestell 17 verbindende Schiebemuffen 20 besteht. An den Enden der Führungsanordnung sind Anschläge 21 angebracht, die die hubartigen Bewegungen der Fördervorrichtung 9 bzw. des Förderorgans 10 begrenzen. Das Versetzen der Fördervorrichtung 9 erfolgt durch eine an einem um eine Rolle umgelenkten Seil 22 mit dem Gestell 17 verbundenen hängenden Last 23, könnte aber auch"motorisch oder mit einem Druckspeicher durchgeführt werden. Durch Änderung der Last 23 kann auch der durch das Anlehnen erreichte Druck der Fördervorrichtung 9 auf den Sta¬ pel 11 variiert werden.The conveying element 10 is leaned against the front end of the stack by a stroke-like wake effect of the conveying device 9, which for this purpose is fastened to a frame 17 which is movable parallel to the feeding direction Z. The latter can be guided both on rails and, as shown, by means of a guide arrangement 18, which consists of at least one guide rod 19 and slidingly guided sliding sleeves 20 connecting it to the frame 17. On Stops 21 are attached to the ends of the guide arrangement and limit the stroke-like movements of the conveying device 9 or the conveying element 10. The displacement of the conveyor 9 is carried by a at a deflected around a pulley cable 22 to the frame associated hanging load 23 17, but could also be carried out "by a motor or with a pressure accumulator. By changing the load 23 can also be the pressure achieved by the leaning the conveyor 9 on the stack 11 can be varied.
Ein gezieltes Nachlaufen und Anpassen des Förderorgans 10 an das Stapelmass erfolgt durch eine nicht dargestellte Steuer¬ vorrichtung, welche die Zuführgeschwindigkeit der Gegenstände 5 in Abhängigkeit der Hublage der Fördervorrichtung 9 in der Führungsanordnung 18 beeinflusst bzw. steuert.A targeted follow-up and adjustment of the conveying member 10 to the stack size is carried out by a control device, not shown, which influences or controls the feed speed of the objects 5 as a function of the stroke position of the conveying device 9 in the guide arrangement 18.
An dem Gestell 17 ist die mit dem Förderorgan 11 zusammenwir¬ kende Abstreifrolle 8 montiert. Diese nur durch Einwirkung eines Gegenstandes antreibbare Abstreifrolle 8 bildet mit dem Förderorgan 11 aufgrund einer gleichsinnigen Drehrichtung ei¬ nen Einzugsspalt 24.The stripping roller 8, which interacts with the conveying element 11, is mounted on the frame 17. This stripping roller 8, which can only be driven by the action of an object, forms a feed gap 24 with the conveying element 11 due to a direction of rotation in the same direction.
An dem Zutrittsende des Einszugsspaltes 24 ist ein von der Abstreifrolle 8 beabstandetes Leitorgan 25 vorgesehen, das den Einzug der einzelnen Gegenstände 5 in den Einzugsspalt 24 un¬ terstützt. Das Leitorgan 25 kann wie gezeichnet, als ein in Förderrichtung der Abstreifrolle 8 vorgelagertes und über de¬ ren Wirkbreite sich erstreckender Blechstreifen ausgebildet sein und mit dem Förderorgan 10 einen Einzugswinkel von etwa 45° einschliessen, womit nicht nur ein schonender Einzug er¬ wirkt sondern ein Blockieren der Gegenstände vor dem Einzugs¬ spalt 24 vermieden werden kann.At the access end of the feed gap 24, a guide member 25 is provided which is spaced from the stripping roller 8 and which supports the feed of the individual objects 5 into the feed gap 24. As shown, the guide member 25 can be designed as a sheet metal strip upstream of the stripping roller 8 and extending over its effective width and include a feed angle of approximately 45 ° with the feed member 10, which not only results in a gentle feed but also a pull-in Blocking of the objects in front of the feed gap 24 can be avoided.
Die dem Förderorgan 10 im Anschluss an die Erfassungs- und Vereinzelungsstelle der Gegenstände 5 zustellbare Abstreifrol¬ le 8 ist mit einem Kraftspeicher 26 antriebsverbunden und ihre Bewegungsrichtung bildet mit der Förderrichtung des Förder- organs 10 einen spitzen Winkel.The scraper roller 8, which can be delivered to the conveying element 10 following the detection and singling point of the objects 5, is drive-connected to a force accumulator 26 and its direction of movement forms with the conveying direction of the conveying organs 10 an acute angle.
Zu diesem Zweck ist die Abstreifrolle 8 mit einer an dem Ge¬ stell 17 befestigten Linearführung 27 verbunden, die durch zwei an einem Support 28 voneinander beabstandet befestigte Führungselemente 29 ausgebildet ist. An den Führungselementen 29 ist ein Lagerbock 30 der Abstreifrolle 8 verschiebbar an¬ geordnet. Der durch Druckfedern gebildete Kraftspeicher 26 ist zwischen dem Support 29 und dem Lagerbock 30 der Abstreifrolle 8 an den Führungselementen 29 angeordnet.For this purpose, the scraper roller 8 is connected to a linear guide 27 fastened to the frame 17, which is formed by two guide elements 29 fastened at a distance from one another on a support 28. A bearing block 30 of the scraper roller 8 is slidably arranged on the guide elements 29. The energy accumulator 26 formed by compression springs is arranged between the support 29 and the bearing block 30 of the scraper roller 8 on the guide elements 29.
In Fig. 3 wird u.a. auf die Ausbildung der Mitnehmer 6 hinge¬ wiesen. Diese weisen in dem dem abziehenden Förderorgan 10 zugewendeten Bereich eine Ausnehmung 31 auf und sind durch den seitlich anschliessenden Teil mit dem Transportband 3 fest verbunden.In Fig. 3, i.a. pointed to the formation of the carriers 6. These have a recess 31 in the area facing the withdrawing conveying member 10 and are firmly connected to the conveyor belt 3 by the laterally adjoining part.
Der in der Mitte der Mitnehmer 6 überstehende Abschnitt 32 dient als Stützvorrichtung über die gesamte Höhe der Gegen¬ stände 5. The section 32 protruding in the middle of the drivers 6 serves as a support device over the entire height of the objects 5.
