Description

Die Erfindung betrifft eine Vorrichtung zum Sammeln von Leerflaschen mit einem von oben her in einer Eingabezone mit den Leerflaschen beschickbaren, als Wagen ausgebildeten Sammelbehälter, dessen Boden von einer oberen Ausgangslage, in Abhängigkeit von der Menge der in den Sammelbehälter gelangenden Leerflaschen, mit Hilfe eines über eine in der Eingabezone angeordnete Niveauabtasteinrichtung ansteuerbaren motorischen Antriebsmechanismus, bis zu einer unteren Endlage schrittweise absenkbar ist.The invention relates to a device for collecting empty bottles with a feed container which can be loaded from above in an input zone with the empty bottles and is designed as a trolley, the bottom of which from an upper starting position, depending on the amount of empty bottles entering the collecting container, with the aid of an over a motorized drive mechanism arranged in the input zone, which can be controlled, can be lowered step by step to a lower end position.

Es ist eine Vorrichtung dieser Art bekannt (GB-A 782380), bei der der motorische Antriebsmechanismus und die Niveauabtasteinrichtung im Wagen selbst integriert sind. Diese teuren Einbauteile können also nur ein relativ beschränktes Aufnahmevolumen für das Leergut versorgen. Ein voller Sammelbehälter muss daher sofort entleert werden, damit er für die weitere Leergutannahme zur Verfügung steht. Ist dies nicht möglich, so müssen Ersatzwagen mit Antriebs- und Abtastaggregaten zur Verfügung gestellt werden. Hinzu kommt, dass die Niveauabtasteinrichtung zwar eine Anpassung der momentanen Eingabehöhe an die eingegebenen Gegenstände ermöglicht, eine Einzelflascheneingabe, die für eine vollautomatische Leergutabrechnung unerlässlich ist, ist dort jedoch nicht vorgesehen. Im Falle der Leergutannahme muss daher immer eine Bedienungsperson bereitstehen, die die eingegebenen Flaschen für die Leergutabrechnung zählt. Weiter ist es bei einem Leergut-Rücknahmegerät an sich bekannt (DE-A 1474874), in einem stationären Gehäuse, an dessen Oberseite ein Eingabemechanismus für die Einzelflascheneingabe angeordnet ist, einen Einstellraum zur zeitweiligen Aufnahme eines Sammelbehälters vorzusehen. Das eingegebene Leergut gelangt zunächst in eine Transportwanne, die sich infolge des Flaschengewichts entgegen einem Gegengewicht unter Schwenkung einer Parallelführung in den Sammelbehälter absenkt. Beim Erreichen des Behälterbodens oder der darüber befindlichen Flasche wird der Auftreffkörper geschwenkt und die Wanne gekippt, so dass die Flasche in den Sammelbehälter gleiten kann. Danach wird die Wanne entlastet und wieder in ihre Ausgangslage zurückbewegt. Während des Transportvorgangs kann keine Flascheneingabe erfolgen. Die Eingabefrequenz ist daher recht beschränkt. Abgesehen davon besteht die Gefahr, dass sich innerhalb des Sammelbehälters eine Flaschenpyramide mit steilen Flanken ausbildet, an denen die eingegebenen Flaschen zu Bruch gehen können.A device of this type is known (GB-A 782380), in which the motor drive mechanism and the level sensing device are integrated in the carriage itself. These expensive installation parts can therefore only supply a relatively limited receiving volume for the empties. A full collection container must therefore be emptied immediately so that it is available for further empties acceptance. If this is not possible, replacement cars with drive and scanning units must be made available. In addition, although the level scanning device enables the current input height to be adapted to the items entered, a single bottle input, which is essential for fully automatic empties accounting, is not provided there. In the event of the acceptance of empties, an operator must therefore always be available to count the bottles entered for the empties settlement. Furthermore, in the case of an empties return device, it is known per se (DE-A 1474874) to provide a setting space for temporarily accommodating a collecting container in a stationary housing, on the upper side of which an input mechanism for the individual bottle input is arranged. The empties entered first enter a transport trough which, due to the weight of the bottle, lowers against a counterweight while pivoting a parallel guide into the collection container. When the bottom of the container or the bottle above it is reached, the impact body is pivoted and the trough is tilted so that the bottle can slide into the collecting container. Then the tub is relieved and moved back to its original position. No bottles can be entered during the transport process. The input frequency is therefore quite limited. Apart from this, there is a risk that a bottle pyramid with steep flanks will form inside the collecting container, on which the bottles entered can break.

Der Erfindung liegt die Aufgabe zugrunde, die bekannte Sammelvorrichtung der eingangs angegebenen Gattung dahingehend zu verbessern, dass der Antriebsmechanismus und die Niveauabtasteinrichtung für eine Vielzahl Sammelbehälterwagen zur Verfügung steht, die über eine Einzelflascheneingabe beschickbar sind.The invention is based on the object of improving the known collecting device of the type specified at the outset in such a way that the drive mechanism and the level sensing device are available for a large number of collecting container wagons which can be loaded via a single bottle input.

Zur Lösung dieser Aufgabe werden die im Patentanspruch 1 angegebenen Merkmale vorgeschlagen. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To achieve this object, the features specified in claim 1 are proposed. Further advantageous refinements and developments of the invention result from the dependent claims.

Der Erfindung liegt der Gedanke zugrunde, dass für eine grössere Anzahl relativ einfach ausgestalteter Sammelbehälterwagen nur ein Antriebsmechanismus und eine Niveauabtasteinrichtung vorzusehen sind, um bei geringstmöglichem Investitionsaufwand eine hohe Aufnahmekapazität für die Leerflaschen zu schaffen. Um dies zu erreichen wird gemäss der Erfindung vorgeschlagen,

  • - dass ein stationäres Gehäuse vorgesehen ist, das einen Einstellraum zur zeitweiligen Aufnahme des Sammelbehälterwagens aufweist,
  • - dass der Antriebsmechanismus und die Niveauabtasteinrichtung in dem stationären Gehäuse angeordnet sind,
  • - dass der Antriebsmechanismus einen beim Einschieben des Sammelbehälterwagens mit dem Behälterboden lösbar kuppelbaren Mitnehmer aufweist und
  • - dass an der Oberseite des Gehäuses ein zur Eingabezone des Sammelbehälterwagens führender Eingabemechanismus für die Einzelflascheneingabe angeordnet ist.
The invention is based on the idea that only a drive mechanism and a level sensing device are to be provided for a relatively large number of relatively simply designed collecting container wagons, in order to create a high holding capacity for the empty bottles with the least possible investment. In order to achieve this, the invention proposes
  • that a stationary housing is provided which has an adjustment space for temporarily accommodating the collecting container wagon,
  • that the drive mechanism and the level sensing device are arranged in the stationary housing,
  • - That the drive mechanism has a detachably coupled driver when inserting the collecting container wagon with the container bottom and
  • - That an input mechanism leading to the input zone of the collecting container wagon is arranged for the single bottle input.

Gemäss einer bevorzugten Ausgestaltung der Erfindung weist der Eingabemechanismus einen aus Sektoren zur Einzelflaschenannahme bestehenden Annahmerotor sowie eine auf die Grösse und die Form der einzugebenden Leerflaschen ansprechende Flaschenabtasteinrichtung auf. Die Flaschenabtasteinrichtung kann dabei mit einem Rechner zur Auswertung und Speicherung der festgestellten Form- und Grössenwerte verbunden sein. Gemäss einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der Eingabemechanismus unterhalb des Annahmerotors zwei nach entgegengesetzten Richtungen in die Eingabezone des Sammelbehälters weisende Flaschenablaufbleche auf, von denen je nach Drehrichtung des Annahmerotors das eine oder andere Flaschenablaufblech mit einer Leerflasche beschickbar ist.According to a preferred embodiment of the invention, the input mechanism has an acceptance rotor consisting of sectors for accepting individual bottles, and a bottle scanning device which responds to the size and shape of the empty bottles to be entered. The bottle scanning device can be connected to a computer for evaluating and storing the determined shape and size values. According to a further advantageous embodiment of the invention, the input mechanism has two bottle drain plates, which point in opposite directions into the input zone of the collecting container, of which one or the other bottle drain plate can be loaded with an empty bottle, depending on the direction of rotation of the acceptance rotor.

Die im Bereich des Eingabemechanismus gehäusefest angeordneten Lichtschranken geben einerseits unter der Einwirkung einer vorbeigleitenden Flasche einen Impuls an einen Rechner und ändern andererseits durch einen zusätzlichen Impuls die Drehrichtung des Annahmerotors, solange nicht eine auf einem Flaschenablaufblech liegengebliebene Flasche eine der Lichtschranken unterbricht. Vorteilhafterweise ist durch die durch eine aus dem Sektor über das Flaschenablaufblech gleitende Flasche unterbrochene Lichtschranke über ein Verzögerungsrelais eine Abwärtsbewegung des Bodens einleitbar, und zwar so lange, bis die Lichtschranke wieder frei ist, wobei anschliessend nach Durchlaufen eines Nachlaufweges der Boden wieder anhebbar ist.The light barriers, which are fixed to the housing in the area of the input mechanism, on the one hand give an impulse to a computer under the influence of a bottle sliding past and, on the other hand, change the direction of rotation of the acceptance rotor by an additional impulse, as long as a bottle which has remained on a bottle drain plate does not interrupt one of the light barriers. Advantageously, a downward movement of the floor can be initiated by the light barrier interrupted by a bottle sliding out of the sector over the bottle drain plate, until the light barrier is free again, after which the floor can be raised again after having followed a caster path.

  • Fig. 3 is a circuit diagram of the collecting device.

Die Sammelvorrichtung besteht im wesentlichen aus einem stationären Gehäuse 2, das einen Einstellraum zur zeitweiligen Aufnahme eines Sammelbehälterwagens 1 aufweist. Der in seiner Höhe verstellbare Boden 3 des Sammelbehälterwagens 1 besitzt seitlich herausragende Auflagezapfen 4, die mit Mitnehmern 5 an einem Kettenantrieb 6 in eine lose Verbindung gebracht sind. Ein Antriebsmotor 7 dient über die Kettenräder 8 zum Heben und Senken des Bodens 3. Ein Endschalter 9 begrenzt die Aufwärtsbewegung des Bodens 3.The collecting device essentially consists of a stationary housing 2, which has an adjustment space for temporarily holding a collecting container wagon 1. The height-adjustable bottom 3 of the collecting container wagon 1 has laterally protruding support pins 4 which are brought into a loose connection with drivers 5 on a chain drive 6. A drive motor 7 serves to raise and lower the floor 3 via the chain wheels 8. A limit switch 9 limits the upward movement of the floor 3.

Im oberen Bereich des Gehäuses befindet sich ein Eingabemechanismus der einen aus offenen Sektoren 11 zur Einzelflaschenannahme bestehenden Annahmerotor 12 aufweist. Weiter ist dort eine auf die Grösse und Form der einzugebenden Leerflaschen ansprechende, vorzugsweise einen Ultraschallkopf 10 aufweisende Flaschenabtasteinrichtung vorgesehen, deren Werte in einem Rechner 13 festgehalten werden.In the upper area of the housing there is an input mechanism which has an acceptance rotor 12 consisting of open sectors 11 for accepting individual bottles. Furthermore, there is provided a bottle scanning device which responds to the size and shape of the empty bottles to be entered, preferably having an ultrasound head 10, the values of which are recorded in a computer 13.

Bei geschlossenen Relais 14 und 15 kann der Annahmerotor 12 anlaufen, und zwar so lange, bis der Strom durch einen Schaltstift 16, der in eine Kerbe 17 einer auf der Welle des Annahmerotors 12 befestigten Scheibe 18 gelangt, unterbrochen wird. Gleichzeitig mit der Unterbrechung wird durch das Eingeben einer Leerflasche die Drehrichtung des Annahmerotors 12 geändert, so dass die wechselseitig über Flaschenablaufbleche 19 gleitenden Leerflaschen 41 nach links und rechts gleichmässig in den Sammelbehälterwagen gelangen, ohne dass dabei eine Flaschenpyramide entsteht, die zu einem Flaschenbruch führen könnte. Um das Herausgleiten der Flaschen aus den Sektoren 11 zu erleichtern, sind am äusseren Ende der die Sektoren 11 begrenzenden Flächen 21 Führungslippen 22 und an dem den Annahmerotor 12 umgebene Gehäuseteil 23 Führungsklappen 24 angeordnet. Weiter sind an dem Gehäuseteil 23 beidseits des Annahmerotors 12 Lichtschranken 25, 26 angeordnet, die durch eine vorbeigleitende Flasche dem Rechner 13 einen entsprechenden Impuls abgeben. Bleibt die Flasche auf dem Flaschenablaufblech 19 liegen, so unterbricht eine der Lichtschranken 25 oder 26 den Stromkreis für den Annahmerotor 12, bis das Flaschenablaufblech 19 wieder frei ist und die behindernde Flasche in den Sammelbehälterwagen 1 gerollt ist. Der Annahmerotor 12 ändert nach jeder Flaschenannahme seine Drehrichtung unter Beeinflussung der Relais 27 und 15. Während der Drehbewegung wird das Relais 15 über das Relais 27 so lange abgeschaltet, bis die Lichtschranke 25 oder 26 durch eine auf dem Flaschenablaufblech 19 liegengebliebene Flasche unterbrochen wird. Bei Unterbrechung der Lichtschranke 25 kann das Relais 27 und bei Unterbrechung der Lichtschranke 26 das Relais 14 nicht mehr ansprechen. Die Drehrichtung des Annahmerotors 12 bleibt dabei so lange erhalten, bis wieder die zweite Lichtschranke 25 oder 26 unterbrochen wird.When the relays 14 and 15 are closed, the acceptance rotor 12 can start until the current is interrupted by a switching pin 16, which comes into a notch 17 in a disk 18 fastened on the shaft of the acceptance rotor 12. Simultaneously with the interruption, the direction of rotation of the acceptance rotor 12 is changed by entering an empty bottle, so that the empty bottles 41 sliding alternately over bottle drain plates 19 pass evenly to the left and right into the collecting container wagon without creating a bottle pyramid that could lead to a bottle breakage . In order to facilitate the sliding out of the bottles from the sectors 11, guide lips 22 are arranged at the outer end of the surfaces delimiting the sectors 11 and guide flaps 24 are arranged on the housing part 23 surrounding the acceptance rotor 12. Furthermore, 12 light barriers 25, 26 are arranged on the housing part 23 on both sides of the acceptance rotor, which give the computer 13 a corresponding impulse by a bottle sliding past. If the bottle remains on the bottle drain plate 19, one of the light barriers 25 or 26 interrupts the circuit for the acceptance rotor 12 until the bottle drain plate 19 is free again and the obstructing bottle is rolled into the collecting container wagon 1. After each bottle acceptance, the acceptance rotor 12 changes its direction of rotation under the influence of the relays 27 and 15. During the rotary movement, the relay 15 is switched off via the relay 27 until the light barrier 25 or 26 is interrupted by a bottle which has remained on the bottle drain plate 19. When the light barrier 25 is interrupted, the relay 27 and when the light barrier 26 is interrupted, the relay 14 can no longer respond. The direction of rotation of the acceptance rotor 12 is maintained until the second light barrier 25 or 26 is interrupted again.

Das Unterbrechen der Lichtschranken 25 und 26 hat gleichzeitig zur Folge, dass das Relais 28 anspricht und den Antriebsmotor 7 in Gang setzt und dabei eine Abwärtsbewegung des Bodens 3 einleitet. Nach frei werden der Lichtschranke 25, 26 wird diese Abwärtsbewegung durch ein Zeitverzögerungsrelais 29 fortgesetzt, um eine unkontrollierte Auf- und Abwärtsbewegung zu vermeiden.The interruption of the light barriers 25 and 26 also has the consequence that the relay 28 responds and starts the drive motor 7 and thereby initiates a downward movement of the floor 3. After the light barrier 25, 26 has become free, this downward movement is continued by a time delay relay 29 in order to avoid an uncontrolled upward and downward movement.

Das Relais 28 ist dabei über beide Lichtschranken 25, 26 in Reihe mit dem Verzögerungsrelais 29 geschaltet. Die Dauer der durch das Relais 29 veranlassten Nachlaufzeit richtet sich bei diesem Vorgang nach dem Durchmesser der grössten annehmbaren Leerflaschen zuzüglich etwa 15 mm. Nach Ablauf dieser Nachlaufzeit bewegt sich der Boden 3 wieder so lange aufwärts, bis die oberste auf dem Boden liegende Flasche einen der beiden unter den Flaschenablaufblechen 19 angeordneten Schaltflügel 30 oder 31, die auf Endschalter 32 oder 33 einwirken, berührt. Dabei wird die Drehrichtung des Antriebsmotors 7 von der Aufwärtsfahrt über das Relais 28 zu der Abwärtsfahrt dadurch erreicht, dass nach Ablauf der Nachlaufzeit das Relais 28 abfällt, wobei die Endschalter 32 und 33 durch die vorher erfolgte Abwärtsfahrt freigeworden sind. Dadurch aber zieht ein Relais 34 an, wodurch der Boden 3 wieder nach oben fährt, bis zur Schliessung eines der Endschalter 32 oder 33 an den Schaltflügeln 30 oder 31. Durch diese Massnahme wird ein sehr kleiner Abstand zwischen den jeweils in den Sammelbehälterwagen 1 eingegebenen Leerflaschen und dem Flaschenablaufblech 19 eingehalten und dadurch ein Flaschenbruch vermieden.The relay 28 is connected in series with the delay relay 29 via both light barriers 25, 26. The duration of the run-on time caused by the relay 29 depends on the diameter of the largest acceptable empty bottles plus about 15 mm. After this delay time has elapsed, the bottom 3 moves upwards again until the uppermost bottle lying on the bottom touches one of the two switching vanes 30 or 31 arranged under the bottle drain plates 19, which act on limit switches 32 or 33. The direction of rotation of the drive motor 7 from the upward travel via the relay 28 to the downward travel is achieved in that the relay 28 drops out after the overrun time, the limit switches 32 and 33 being released by the previous downward travel. As a result, however, a relay 34 picks up, causing the bottom 3 to move upward again until one of the limit switches 32 or 33 on the switching vanes 30 or 31 closes and the bottle drain plate 19 adhered to, thereby avoiding bottle breakage.

Hat sich nun der Sammelbehälterwagen 1 weitgehend mit eingegebenen Leerflaschen gefüllt und der Boden 3 dabei gesenkt, so wird ein Signal durch einen Schalter 35 ausgelöst, der anzeigt, dass der nunmehr gefüllte Sammelbehälterwagen 1 durch einen leeren ersetzt werden soll.If the collecting container wagon 1 has now largely been filled with empty bottles entered and the floor 3 has been lowered, a signal is triggered by a switch 35 which indicates that the collecting container wagon 1 which is now filled should be replaced by an empty one.

Erreicht anschliessend der Boden 3 seine untere Endlage, so wird die Steuerungsanlage durch einen Endschalter 36 spannungslos und gleichzeitig erscheint ein Signal an einem Anzeigeteil 37, das anzeigt, dass die Flaschenannahme gesperrt ist.If the bottom 3 then reaches its lower end position, the control system is de-energized by a limit switch 36 and at the same time a signal appears on a display part 37 which indicates that the bottle reception is blocked.

Ein über ein Türschloss 39 betätigbarer Schalter 38 bewirkt ein Anlaufen des Antriebsmotors 7, auch wenn der Endschalter 36 noch nicht geschlossen sein sollte, wobei das Relais 28 vorrangig anzieht, bis der Endschalter 36 erreicht ist. Dadurch ist sichergestellt, dass der Boden 3 nach Öffnen einer Gehäusetür sich immer in seiner unteren Endlage befindet. Die Sammelvorrichtung kann dahingehend noch erweitert werden, dass die durch den Rechner 13 ermittelten Werte auf einen Drucker 40 übertragen werden, der das zu erwartende Flaschenpfand ermittelt und anzeigt.A switch 38, which can be actuated via a door lock 39, causes the drive motor 7 to start, even if the limit switch 36 should not yet be closed, the relay 28 picking up primarily until the limit switch 36 is reached. This ensures that the bottom 3 is always in its lower end position after opening a housing door. The collecting device can be expanded so that the values determined by the computer 13 are transmitted to a printer 40 which determines and displays the bottle deposit to be expected.
