Description

Die Erfindung betrifft eine Vorrichtung zur Vereinzelung und zur Übergabe von flachem Stückgut gemäß dem Oberbegriff des Anspruchs 1 (US-A-3861669).The invention relates to a device for separating and transferring flat General cargo according to the preamble of claim 1 (US-A-3861669).

Die auf Postsendungen wie Briefen, Postkarten, Päckchen und dergleichen, als Kennzahl für einen Ort, einen Zustellbereich, ein Postfach oder einen Großempfänger anzugebenden, maschinenlesbaren Postleitzahlen, ermöglichen eine rasche maschinelle Verteilung der Post. Das Sortieren der ankommenden Postsendungen erfolgt beispielsweise mit Hilfe von steuerbaren Stückgutträgern, die in speziellen Beladeplätzen mit jeweils einer Postsendung beladen werden, und diese Postsendung dann an einen der jeweiligen Postleitzahl zugeordneten Sortierbehälter oder ein entsprechendes Sortierfach abgeben. Da die Sortierbehälter oder Sortierfächer in verschiedenen Ebenen angeordnet sein können, müssen die an Fördereinrichtungen umlaufenden Stückgutträger gegebenenfalls auch verschiedene Höhenlagen überbrücken können. Nach der Übergabe der Post sendung an den zugeordneten Sortierbehälter oder das zugeordnete Sortierfach, können die leeren Stückgutträger beim Passieren eines Beladeplatzes erneut mit einer Postsendung beladen werden. Das Beladen der Stückgutträger erfolgt beispielsweise mit Hilfe eines umlaufenden Flügelrades, dessen Flügel Zellen bilden, die das bereits vereinzelte und auf einer Fördereinrichtung ankommende Stückgut aufnehmen und an die umlaufenden Stückgutträger abgeben. Die Vereinzelung und die Übergabe des Stückguts an die zu dem Flügelrad führende Fördereinrichtung, muß dabei mit einer an die Verarbeitungsgeschwindigkeit der gesamten Sortiereinrichtung angepaßten, relativ hohen Genauigkeit vorgenommen werden.The on mail items such as letters, postcards, packages and the like, as a key figure for a location, a delivery area, a mailbox or a bulk recipient, machine-readable postcodes, enable a quick machine Distribution of mail. Sorting the incoming Postal items are, for example, controlled General cargo carriers that are in special loading areas with each loaded with a mail item, and this mail item then to one assigned to the respective zip code Hand in the sorting container or an appropriate sorting compartment. Because the sorting containers or bins in different Levels can be arranged on the conveyors circulating general cargo carriers, if necessary, also various Can bridge high altitudes. After the handover the mail item to the assigned sorting container or the assigned sorting bin, the empty general cargo carriers when passing a loading area again with a mail item be loaded. The general cargo carriers are loaded for example with the help of a rotating impeller, the Wing cells form that are already isolated and open a piece of incoming goods arriving and receiving deliver the circulating general cargo carriers. The isolation and the transfer of the piece goods to the one leading to the impeller Conveyor, must be at a processing speed adapted to the entire sorting device, relatively high accuracy.

Vergleichbare Sortieraufgaben ergeben sich auch bei der sogenannten Remission von Zeitschriften oder Zeitungen. Die vom Einzelhandel nicht verkauften Druckschriften werden hier an den Großhändler zurückgeschickt und dort erfaßt und zur Vernichtung aussortiert oder zur Rücksendung an die jeweiligen Verlage neu sortiert.Comparable sorting tasks also arise with the so-called Remission from magazines or newspapers. The ones from Retail unsold pamphlets are listed here sent the wholesaler back and recorded there and for annihilation sorted out or sent back to the respective Newly sorted publishers.

Die automatische Handhabung und insbesondere die Vereinzelung von unverpackten Zeitschriften oder Zeitungen, bereitet sowohl bei der Postgutverteilung, als auch bei der Remission der Druckschriften erhebliche Schwierigkeiten. So besteht bei der Handhabung der Druckschriften mit automatischen Greifeinrichtungen stets die Gefahr, daß sich die Druckschriften Öffnen, was neben einer Beschädigung oder Zerstörung der Druckschriften, insbesondere auch zu einer Unterbrechung des gesamten Sortierprozesses führt.The automatic handling and in particular the separation from unwrapped magazines or newspapers, prepares both in mail distribution, as well as in remission of the publications considerable difficulties. So there is at the handling of the publications with automatic gripping devices always the danger that the publications will open, in addition to damage or destruction of the publications, especially to an interruption of the whole Sorting process leads.

Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, mit geringem Aufwand eine rasch und zuverlässig arbeitende Vorrichtung zur Vereinzelung und zur Übergabe von flachem Stückgut zu schaffen, die insbesondere eine sichere Handhabung von Zeitschriften, Zeitungen, Katalogen und dergleichen gewährleisten soll.The invention specified in claim 1 is based on the problem a quickly and reliably working with little effort Device for separating and transferring to create flat general cargo, which is particularly safe Handling of magazines, newspapers, catalogs and the like guarantee.

Eine erfindungsgemäße Vorrichtung kann bei der Remission von Zeitschriften oder Zeitungen, in Öffentlichen Postämtern oder in den Hauspostzentralen großer Firmen eingesetzt werden. Darüber hinaus kann eine erfindungsgmäße Vorrichtung aber auch beispielsweise in Lagersystemen oder Kommissionierautomaten für vergleichbare Aufgaben eingesetzt werden, bei welchen flaches, stapelbares Stückgut vereinzelt und an eine Fördereinrichtung übergeben werden soll.A device according to the invention can be used in the remission of Magazines or newspapers, in public post offices or are used in the in-house mail centers of large companies. In addition, however, a device according to the invention also in storage systems or order picking machines, for example are used for comparable tasks in which flat, stackable general cargo isolated and to one Funding facility to be handed over.

Befindet sich der Rücken oder Falz der Druckschriften in Umlaufrichtung des Mitnehmerbandes gesehen hinten, so werden nicht geheftete Druckschriften zusammengehalten und auch eventuell vorhandene lose Beilagen können nicht herausfallen. Durch die aufrechte Stellung des Stückguts wird die Vereinzelung begünstigt, da das in der Abholposition bereitgestellte Stückgut nach oben abgezogen wird, während das nächste Stückgut durch sein Eigengewicht der Abzugskraft entgegenwirkt. Da das Stückgut nicht gegen eine Kante abgezogen werden muß, wird auch eine Vereinzelung von Stückgut mit unterschiedlichen Stärken ermöglicht.The invention is based on the finding that one with a Suction opening or multiple suction openings provided, endless all-round conveyor belt very good for separation of magazines or newspapers is suitable while on the subsequent path until the printed matter is dropped extremely safe guidance between on a conveyor the carrier belt and an assigned pressure belt results. Is the spine or fold of the printed matter seen in the direction of rotation of the driving belt at the back, so non-stapled documents held together and also loose inserts, if any, cannot fall out. The uprighting of the piece goods makes the separation favored, as that provided in the pick-up position General cargo is withdrawn upwards while the next general cargo counteracts the pull-off force with its own weight. There the piece goods do not have to be pulled off against an edge, is also a separation of general cargo with different Strengths made possible.

Die Figuren 1 und 2 zeigen in stark vereinfachter schematischer Darstellung eine Vorrichtung zur Vereinzelung und zur Übergabe von Stückgut S an eine mit F bezeichnete Fördereinrichtung in der Seitenansicht bzw. in der Draufsicht. Zur Aufnahme des hier in Form von Zeitschriften und Zeitungen unterschiedlichen Formats und unterschiedlichen Gewichts vorliegenden Stückguts S und zur Bereitstellung dieses Stückguts S in einer vorderen Abholposition A, ist eine mit E bezeichnete Einrichtung vorgesehen. Bei dieser Einrichtung E handelt es sich um einen schrittweise in Richtung auf die Abholposition A antreibbaren, horizontal ausgerichteten Bandförderer, auf welchen das Stückgut S von Hand stapelweise in aufrechter, leicht nach vorne geneigter Stellung aufgebracht wird. Das Förderband des in Figur 2 nicht dargestellten Bandförderers, wird dabei durch mehrere parallel im Abstand zueinander verlaufende Riemen gebildet.Figures 1 and 2 show in a highly simplified schematic Representation of a device for separating and Transfer of piece goods S to a conveyor designated F in side view or in plan view. For Inclusion of the different here in the form of magazines and newspapers Format and different weight present General cargo S and for the provision of this general cargo S in a front pick-up position A is one labeled E Facility provided. At this facility E acts it is a gradual move towards the pickup position A drivable, horizontally aligned belt conveyor, on which the piece goods S are stacked by hand in an upright, is applied slightly forward inclined position. The conveyor belt of the belt conveyor, not shown in FIG. 2, is thereby parallel to each other by several running straps formed.

Zum Ergreifen des in der Abholposition A bereitgestellten Stückguts S ist ein oberhalb der Fördereinrichtung F um eine Rolle RO und eine Trommel T endlos umlaufendes Mitnehmerband MB vorgesehen, in dessen drei parallel verlaufende Abschnitte jeweils fünf Saugöffnungen SO eingebracht sind. Die fünf Saugöffnungen SO eines Bandabschnittes sind jeweils über eine auf der Rückseite des Bandes angeordnete Saugkammer SK mit einer in der Zeichnung nicht näher dargestellten Vakuumquelle verbindbar. Das in der Abholposition A bereitgestellte Stückgut S wird somit durch die Saugwirkung der Saugöffnungen SO von dem Mitnehmerband MB ergriffen und in tangentialer Richtung der Trommel T vom verbleibenden Stapel leicht schräg nach oben abgezogen. Unmittelbar im Anschluß an diese Vereinzelungsbewegung wird das Stückgut S dann in den öffnungensspalt zwischen dem Mitnehmerband MB und einem mit AB bezeichneten Andruckband eingezogen. Dieses endlos umlaufende Andruckband AB ist über drei Umlenkrollen UR derart geführt, daß es die Trommel T im gewünschten Führungsbereich bis zur Abwurfstelle hin umschlingt. Die Umlaufrichtung des in Figur 2 nicht dargestellten Andruckbandes AB ist in Figur 1 durch einen Pfeil PF aufgezeigt. Das Andruckband AB kann dabei angetrieben werden oder aber auch durch das mit der Geschwindigkeit v umlaufende Mitnehmerband MB reibschlüssig mitgenommen werden.For gripping the one provided in pick-up position A. General cargo S is one above the conveyor F by one Roll RO and a drum T endless revolving conveyor belt MB provided in its three parallel sections five suction openings SO are introduced in each case. The five suction openings SO of a band section are each one suction chamber SK arranged on the back of the belt a vacuum source not shown in the drawing connectable. The general cargo provided in pick-up position A. S is thus SO through the suction effect of the suction openings gripped by the carrier belt MB and in the tangential direction the drum T is slightly oblique from the remaining stack subtracted upwards. Immediately following this separation movement the general cargo S is then in the opening gap between the carrier belt MB and one labeled AB Pressure tape pulled in. This endless pressure tape AB is guided over three pulleys UR in such a way that it is the drum T in the desired guide area up to Throws around the discharge point. The direction of rotation of the in figure 2, not shown, pressure tape AB is shown in FIG an arrow PF is shown. The pressure belt AB can be driven be, or also by speed v The entraining conveyor belt MB is frictionally entrained become.

Die als Stückgut S auf dem Förderband der Einrichtung E mit dem Rücken oder Falz nach unten aufgestellten und nach vorne zum Mitnehmerband MB bzw. zur Trommel T hin leicht geneigten Zeitschriften oder Zeitungen, können durch zwei im Abstand zueinander angeordnete Abweiser AW von einer Berührung des Mitnehmerbandes MB abgehalten werden. Soll dann das in der Abholposition A bereitgestellte Stückgut S über die Ansaugöffnungen AO ergriffen werden, so werden die beiden im Bereich von Lücken L zwischen den Abschnitten des Mitnehmerbandes MB angeordneten Abweiser AW in zugeordnete rillenförmige Vertiefungen V der Trommel T zurückgezogen. Das Ein- und Ausrücken der auf der Welle WE befestigten Abweiser AW erfolgt durch entsprechende Drehungen der Welle WE.The as piece goods S on the conveyor belt of the device E with the back or fold down and forward slightly inclined towards the carrier belt MB or the drum T. Magazines, or newspapers, can be separated by two to each other deflectors AW from a touch of the Carrier belt MB are held. Should that be in the Pick-up position A provided piece goods S via the suction openings AO are taken, so the two are in the area of gaps L between the sections of the carrier belt MB arranged deflector AW in assigned groove-shaped Recesses V of the drum T withdrawn. Engaging and disengaging the AW deflector attached to the shaft WE by corresponding rotations of the shaft WE.

Das nur in Figur 1 dargestellte Andruckband AB ist in mehrere parallel verlaufende Riemen unterteilt. Auf diese Weise kann in dem Bereich zwischen den drei Umlenkrollen UR ein optischer Sensor SS angeordnet werden, der an dieser Stelle zwischen zwei Riemen Anfang und/oder Ende des jeweils vom Mitnehmerband MB mitgenommenen Stückguts S erfaßt. Aus Figur 2 ist ersichtlich, daß das Signal SI des Sensors SS einer Steuereinrichtung SE zugeführt wird. Diese Steuereinrichtung SE beeinflußt ihrerseits über ein Ausgangssignal AS einen Antriebsmotor AM, welcher über einen Riementrieb RT und die mit TW bezeichnete Trommelwelle die Trommel T antreibt. Die Lagerung der Trommelwelle TW ist in Figur 2 durch Kugellager KL angedeutet.The pressure tape AB shown only in Figure 1 is in several parallel straps divided. That way in the area between the three pulleys UR an optical Sensor SS can be arranged at this point between two straps at the beginning and / or end of each of the driving belt MB captured piece goods S recorded. From Figure 2 it can be seen that the signal SI of the sensor SS of a control device SE is supplied. This control device SE in turn influences a drive motor via an output signal AS AM, which has a belt drive RT and the with TW designated drum shaft drives the drum T. Warehousing the drum shaft TW is in Figure 2 by ball bearings KL indicated.

Der Sensor SS erfaßt somit die Position des von den Saugöffnungen SO erfaßten Stückguts S auf der Trommel T. Ein vom Sensor SS gegebenenfalls ermittelter Schlupf beim Ergreifen und der Mitnahme des Stückguts S, kann somit über die Steuereinrichtung SE durch eine entsprechende Veränderung der Drehzahl n der Trommel T und damit der Geschwindigkeit v des Mitnehmerbandes MB kompensiert werden.The sensor SS thus detects the position of the suction openings SO registered piece goods S on the drum T. One from Sensor SS, if found, slip when gripping and the transport of the piece goods S, can thus via the control device SE by changing the speed accordingly n the drum T and thus the speed v of the driving belt MB to be compensated.

Bei der das vereinzelte Stückgut S aufnehmenden Fördereinrichtung F handelt es sich im dargestellten Ausführungsbeispiel um einen Bandförderer, dessen nicht näher bezeichnetes Förderband sich mit der Geschwindigkeit u in Transportrichtung bewegt. Auf dem Förderband schaffen Querrippen QR eine Teilung t für die Aufnahme und den Weitertransport des Stückguts S. Die Geschwindigkeit u der Fördereinrichtung F und die Drehzahl n der Trommel T bzw. die Geschwindigkeit v des Mitnehmerbandes MB sind derart aufeinander abgestimmt, daß eine Übergabe des Stückguts S an die Fördereinrichtung F bei jeder Teilung t oder jeweils einem ganzzahlige Vielfachen der Teilung t der Fördereinrichtung F erfolgt. Durch Veränderung der Drehzahl n der Trommel T bzw. der Geschwindigkeit v des Mitnehmerbandes MB kann die Übergabe des Stückguts S gegebenenfalls auch auf eine ungleichmäßige Teilung der Fordereinrichtung F abgestimmt werden.At the conveyor device that receives the individual piece goods S. F is in the illustrated embodiment a belt conveyor, the unspecified Conveyor belt moving at speed u in the direction of transport emotional. Cross ribs QR create one on the conveyor belt Division t for picking up and transporting the piece goods S. The speed u of the conveyor F and the Speed n of the drum T or the speed v of the driving belt MB are coordinated so that a Transfer of the piece goods S to the conveyor F at each Division t or an integer multiple of the division t of the conveyor F takes place. By changing the Speed n of the drum T or the speed v of the driving belt MB can transfer the general cargo S if necessary also on an uneven division of the conveyor F can be matched.

Die vorstehend beschriebene Vorrichtung zur Vereinzelung und zur Übergabe von Stückgut S führt zu einem umlaufenden Flügelrad, dessen durch die einzelnen Flügel gebildeten Zellen das auf der Fördereinrichtung F ankommende Stückgut S aufnehmen und nach einer entsprechenden Drehung an darunter umlaufende Stückgutträger einer Sortiereinrichtung abgeben.The device for separation and described above for the transfer of piece goods S leads to a rotating impeller, the cells formed by the individual wings pick up the piece goods S arriving on the conveyor device F. and after a corresponding rotation on the rotating one below Deliver general cargo carriers to a sorting facility.

    has an endlessly circulating pressure-exerting belt (AB) assigned to the carry-along belt (MB) in the region downstream of the pick-position (A),
    the item (S), which is supplied in the pick-up position (A) in the upright state, being grasped by the suction opening (SO) of the carry-along belt (MB) in the region of the suction chamber (SK), being drawn off upwards from the remaining stack of items (S), being conveyed further between the carry-along belt (MB) and the pressure-exerting belt (AB), and then being discharged onto the conveying device (F).
  2. Apparatus according to Claim 1, characterized in that the device (E) for receiving and for supplying the items (S) is formed by a belt conveyor which can be driven in a stepwise manner in the direction of the pick-up position (A) and on which the items (S) are positioned in stacks in the upright state.
  3. Apparatus according to Claim 2, characterized in that the belt conveyor is aligned at least approximately horizontally, and in that the items (S) positioned thereon are inclined towards the carry-along belt (MB).
  4. Apparatus according to one of Claims 1 to 3, characterized in that the carry-along belt (MB) is guided over a roller (RO), arranged beneath the pick-up position (A), and over a drum (T).
  5. Apparatus according to Claim 4, characterized in that the pressure-exerting belt (AB) is guided over three deflecting rollers (UR) and over the drum (T).
  6. Apparatus according to one of Claims 1 to 5, characterized in that the carry-along belt (MB) is subdivided into at least three mutually parallel sections, and in that outwardly pivotable deflectors (AW) for the item (S) supplied are arranged in the gaps (L) between the sections, in the region of the pick-up position (A).
  7. Apparatus according to one of Claims 1 to 6, characterized in that the speed (u) of the conveying device (F) and the speed (v) of the carry-along belt (MB) are coordinated with one another such that the transfer of items (S) to the conveying device (F) takes place with each division (t), or in each case a wholenumbered multiple of the division (t), of the conveying device (F).
  8. Apparatus according to one of Claims 1 to 7, characterized in that, in the case of two or more suction openings (SO) distributed in the longitudinal direction of the carry-along belt (MB), the spacing of said openings in the longitudinal direction is coordinated with the division (t) of the conveying device (F).
  9. Apparatus according to one of Claims 1 to 8, characterized in that the position in which the item (S) grasped by a suction opening (SO) is located on the carry-along belt (MB) is determined with the aid of a sensor (SS), and in that slippage detected by the sensor (SS) when the item (S) is grasped and carried along is compensated, via a control device (SE), by the speed (v) of the carry-along belt (MB) being changed correspondingly.
  10. Apparatus according to Claims 4 and 9, characterized in that the carry-along belt (MB) is driven via the drum (T), and in that the control device (SE) changes the rotational speed (n) of the drum (T).
