Description

Die Erfindung betrifft einen Fallklappenschacht für Selbstverkäufer, bei dem an Schachtwänden in einer bestimmten Fallklappenschachtteilung Klappen schwenkbar gelagert sind und jede Klappe sich in ihrer Aufnahmestellung mit einem Finger auf einem federnden Rastglied abstützt und bei dem an einer Schachtwand wenigstens eine vertikale Schiene verläuft, an der ein Schlitten verschiebbar geführt ist, welcher eine Nase zur Verschwenkung des Rastgliedes aufweist, wobei parallel zu der Schiene eine Hubstange mit einer Zahnreihe verläuft, deren Teilung der kleinsten Fallklappenschachtteilung entspricht und an der sich der Schlitten über eine Fortschaltklinke abstützt und an dem Schlitten ein Anschlag vorgesehen ist.The invention relates to a fall flap shaft for self-sellers, in which flaps are pivotally mounted on shaft walls in a certain fall flap division and each flap is supported in the receiving position with a finger on a resilient locking member and in which at least one vertical rail runs on a shaft wall, on which a Carriage is slidably guided, which has a nose for pivoting the locking member, with a lifting rod with a row of teeth running parallel to the rail, the division of which corresponds to the smallest drop flap division and on which the carriage is supported by a indexing pawl and a stop is provided on the carriage .

Ein derartiger Fallklappenschacht ist in der DE-A-1 907 824 beschrieben. Bei dem Fallklappenschacht der DE-A-1 907 824 ist eine der Anzahl der Fallklappen entsprechende Anzahl von einzelnen Rastgliedern vorgesehen. Dies ist aufwendig. Darüber hinaus ist außer der gezahnten Hubstange eine ortsfeste Rastleiste nötig. Dieser Aufbau ist umständlich und kann zu Justierungsschwierigkeiten führen. Außerdem ist ungünstig, daß beim Zurückstellen des Schlittens kein Rückstellen der Klappen erfolgt, so daß diese einzeln von Hand zurückgestellt werden müssen.Such a flap chute is described in DE-A-1 907 824. In the fall flap shaft of DE-A-1 907 824, a number of individual latching elements corresponding to the number of fall flaps is provided. This is expensive. In addition to the toothed lifting rod, a fixed locking bar is required. This structure is cumbersome and can lead to adjustment difficulties. In addition, it is disadvantageous that when the carriage is reset, the flaps are not reset, so that they must be individually reset by hand.

Ein weiterer Fallklappenschacht ist in der DE-PS 113 307 beschrieben. Günstig bei diesem Fallklappenschacht ist, daß die Klappen zum Abschwenken nicht gegen horizontal liegende Federn verschoben werden müssen. Solche Federn würden den Fallklappensdhacht schwergängig machen und einen beträchtlichen zusätzlichen Bauaufwand bedeuten. Nachteilig ist bei der DE-PS 113307, daß hier ein Kraftspeicher zum Antrieb des Schlittens vorgesehen sein muß und daß die Rastglieder als Einzelglieder ausgebildet sind.Another fall flap shaft is described in DE-PS 113 307. It is favorable with this drop-down flap shaft that the flaps do not have to be moved against horizontally lying springs for pivoting down. Such springs would make the trap door stiff and involve considerable additional construction. A disadvantage of DE-PS 113307 is that an energy accumulator must be provided for driving the slide and that the locking elements are designed as individual elements.

In der AT-PS 820 ist ein Fallklappenschacht gezeigt, bei dem die Steuerung der Fallklappen mittels einer sich schrittweise einrollenden Spiralfeder erfolgt. In einer Ausführung sind dabei die Fallklappen im Bereich ihrer Lagerstellen mit einer Schräge versehen, über die die Klappen in ihrer Warenaufnahmestellung gehalten sind. Dies erlaubt zwar eine einfache Rückstellung der Klappen, ist jedoch mechanisch unbefriedigend, da die Klappen sich an ihrem längeren Hebelarm nur aneinander abstütien. In einer anderen Ausführung ist gegenüber den Lagerzapfen jeweils ein separates, zweiteiliges Rastglied vorgesehen.AT-PS 820 shows a drop flap shaft in which the drop flaps are controlled by means of a spiral spring that gradually rolls in. In one embodiment, the drop flaps are provided with a bevel in the area of their bearing points, by means of which the flaps are held in their goods receiving position. Although this allows the flaps to be reset easily, it is mechanically unsatisfactory since the flaps only abut each other on their longer lever arm. In another embodiment, a separate, two-part locking member is provided in each case opposite the bearing journal.

. In der AT-PS 298130 ist ein Fallklappenschacht beschrieben, bei dem die Klappen einzeln horizontal federnd gelagert sind. Mittels einer drehbaren Betätigungsstange, die sich über die Höhe des Fallklappenschachts erstreckt, lassen sich die Klappen nacheinander dadurch auslösen, daß ein Nocken der Betätigungsstange jeweils eine Klappe horizontal verschiebt, so daß sich deren Finger vom Rastglied löst. Die den einzelnen Klappen zugeordneten Nocken der Be tätigungsstange sind mit einem von unten nach oben zunehmenden Abstand angeordnet. Un günstig dabei ist, daß je mehr Fächer bedient werden müssen, desto größer der Hub der Stange wird und leicht Höhen annimmt, die in üblichen Selbstverkäufern nicht zur Verfügung stehen. Jede Klappe mit zwei Federn an einer Achse horizontal verschiebbar zu lagern, ist aufwendig Darüber hinaus ist auch die Rückstellung der Klappen umständlich. . AT-PS 298130 describes a drop flap shaft in which the flaps are individually spring-mounted horizontally. By means of a rotatable actuating rod, which extends over the height of the drop flap shaft, the flaps can be triggered one after the other in that a cam of the actuating rod displaces one flap horizontally, so that its finger is released from the locking member. The individual flaps assigned cams of the actuating rod are arranged with an increasing distance from bottom to top. It is unfavorable that the more compartments that need to be served, the greater the stroke of the rod becomes and easily assumes heights that are not available in normal self-sellers. Storing each flap with two springs horizontally displaceable on one axis is complex. In addition, the resetting of the flaps is also cumbersome.

Aufgabe der Erfindung ist es, einen Fallklap penschacht der eingangs genannten Art vorzu schlagen, bei dem die Klappen nicht verschoben werden müssen und darüber hinaus die Rastglieder sowie der Antrieb des Schlittens einfach gestaltet ist.The object of the invention is to propose a Fallklap penschacht of the type mentioned, in which the flaps do not have to be moved and, moreover, the locking members and the drive of the carriage is simple.

Erfindungsgemäß ist obige Aufgabe bei einem Fallklappenschacht der eingangs genannten Art dadurch gelöst, daß der Schlitten mit seinem Anschlag auf einem der Rastglieder aufsteht und daß die Rastglieder Zähne eines Re chens aus einem federnden Material sind.According to the invention the above object is achieved in a chute of the type mentioned in that the carriage stands up with its stop on one of the locking members and that the locking members teeth of a re are made of a resilient material.

Damit wird bei jeder Betätigung des Fallklappenschachts die Hubstange um eine Fallklappenschachtteilung angehoben und nimmt über die Fortschaltklinke den Schlitten mit, der mit seiner Nase immer jeweils die nächstobere Fallklappe auslöst. Durch den Anschlag des Schlittens ist sichergestellt, daß er in einer hochgehobenen Stellung auf einem der Rastglieder aufsteht, bis er erneut betätigt wird. Zusätzliche Blockiermittel für den Schlitten erübrigen sich damit. Sämtliche Rastglieder sind von einem ein zigen Bauteil, nämlich einem Rechen, gebildet, der beispielsweise aus Federstahl besteht, so daß die Rastglieder einzeln ausfedern können und dennoch die Herstellung und Montage der Rastglieder einfach ist.With each actuation of the trapdoor shaft, the lifting rod is raised by one trapdoor division and takes the slide with it, which always triggers the next top trapdoor with its nose. The stop of the carriage ensures that it stands in a raised position on one of the locking members until it is actuated again. This eliminates the need for additional blocking agents for the sled. All locking elements are formed by a single component, namely a rake, which consists, for example, of spring steel, so that the locking elements can rebound individually and yet the manufacture and assembly of the locking elements is simple.

Um den Fallklappenschacht auf verschiedene, jedoch untereinander gleiche Fallklappenschachtteilungen, d. h. Fachhöhen umrüsten zu können, ist der bei einer Betätigung erfolgende Hub der Hubstange verstellbar. Die Hubhöhe entspricht der Fachhöhe. Sie ist jedoch nicht von der Anzahl der Fächer abhängig.In order to divide the chute shaft into different, but mutually identical, chute divisions, i. H. To be able to convert compartment heights, the stroke of the lifting rod that occurs when actuated is adjustable. The lifting height corresponds to the compartment height. However, it is not dependent on the number of subjects.

In vorteilhafter Ausgestaltung der Erfindung sind an den Fallklappen bei ihren Lagerstellen Rückstellschrägen vorgesehen, die bei abgeschwenkten Fallklappen in die Bewegungsbahn eines am Schlitten angeordneten Rückstellgliedes ragen. Zur Rückstellung des Schlittens ist an diesem ein Kupplungshebel gelagert, der die Fortschaltklinke von der Zahnreihe entkoppelt und das Rückstellglied gegen die Rückstellschrägen drückt.In an advantageous embodiment of the invention, resetting bevels are provided at the bearing flaps at their bearing points, which project into the movement path of a resetting member arranged on the slide when the flap flaps are pivoted away. To reset the slide, a coupling lever is mounted on it, which decouples the indexing pawl from the row of teeth and presses the reset element against the reset slopes.

Es ist damit erreicht, daß mit einer einzigen Bewegung sowohl der Schlitten zurückgestellt als auch die Klappen wieder in ihre Stapelstellung gebracht werden können.It is thus achieved that both the carriage can be reset and the flaps can be brought back into their stacking position with a single movement.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der folgenden Beschreibung eines Ausführungsbeispiels. In der Zeichnung zeigt

  • Fig. 1 eine Teil-Seitenansicht eines Fallklappenschachts und
  • Fig. 2 eine Teil-Rückansicht des Fallklappenschachts nach Fig. 1.
Further advantageous refinements of the invention result from the following description of an exemplary embodiment. In the Drawing shows
  • Fig. 1 is a partial side view of a trap door and
  • FIG. 2 shows a partial rear view of the trap door shaft according to FIG. 1.

An Seitenwänden 1 und 2 eines Fallklappenschachts ist eine Mehrzähl von Klappen 3 im gleichen Abstand gelagert. Jede Klappe 3 weist zwei Zapfen 4 und 5 auf, mit denen sie in Ausnehmungen 6 der Seitenwände 1 und 2 eingehängt und um die sie verschwenkbar ist. Jede Klappe 3 weist an der den Ausnehmungen 6 gegenüberliegenden Seite nahe bei der Seitenwand 1 einen Finger 7 auf.A plurality of flaps 3 are mounted at the same distance on side walls 1 and 2 of a drop flap shaft. Each flap 3 has two pins 4 and 5, with which it is hung in recesses 6 of the side walls 1 and 2 and about which it can be pivoted. Each flap 3 has a finger 7 on the side opposite the recesses 6 close to the side wall 1.

An der Rückseite (vgl. Fig. 2) des Fallklappenschachts ist ein Rechen 8 angeordnet, der aus Federstahl besteht. Zähne 9 des Rechens 8 bilden Rastglieder, auf denen die Finger 7 nicht abgeklappter Fallklappen aufliegen.A rake 8, which is made of spring steel, is arranged on the rear (cf. FIG. 2) of the chute shaft. Teeth 9 of the rake 8 form locking elements on which the fingers 7 of the hinged drop flaps rest.

An der Seitenwand 1 sind zwei parallele Schienen 10 und 11 befestigt. Von den Schienen 10 und 11 ist ein Schlitten 12 geführt. Dieser untergreift mit vier Rollen 13 die Schienen 10 und 11.On the side wall 1, two parallel rails 10 and 11 are attached. A slide 12 is guided by the rails 10 and 11. This engages under rails 10 and 11 with four rollers 13.

Am Schlitten 12 ist eine Nase 14 ausgebildet, welche zwischen zwei Rastglieder 9 ragt. Sie überragt die Rastglieder 9 ebenso weit oder wenig mehr wie die Finger 7. An der Nase 14 ist eine Auslenkschräge 15 und ein Anschlagrand 16 ausgebildet.A nose 14 is formed on the slide 12, which protrudes between two locking members 9. It projects beyond the locking members 9 as much or as little as the fingers 7. A deflection bevel 15 and a stop edge 16 are formed on the nose 14.

An der Seitenwand 1 ist weiterhin verschieblich eine Hubstange 17 gelagert, an der eine Zahnreihe 18 ausgebildet ist. An einem Fortsatz 19 des Schlittens 12 ist um eine Achse 20 schwenkbar eine Fortschaltklinke 21 angeordnet. Diese ist mittels einer Zugfeder 22 gegen den Schlitten 12 vorgespannt. Sie greift mit einer Kuppe 23 an einen der Zähne der Zahnreihe 18. Die Hubstange 17 ist mit einem Hubglied 24 verstellbar verbunden. Es ist hierfür im Hubglied 24 ein Langloch 25 parallel zur Hubstange 17 laufend vorgesehen. Die Hubstange 17 weist innerhalb des Langlochs 25 Gewindebohrungen 26 auf, deren Abstand der Teilungsbreite T entspricht. In eine der Gewindebohrungen 26 ist eine Schraube 27 geschraubt, welche nicht zur starren Verbindung von Hubstange 17 und Hubglied 24 führt. Die Schraube 27 arbeitet vielmehr mit dem unteren Rand des Langlochs 25 als Anschlag zusammen. Unten am Hubglied 24 ist an einem Zapfen 28 ein Betätigungshebel 29 an einer Achse 30 gelagert. Der Betätigungshebel 29 ist mittels der diesem Fallklappenschacht zugeordneten, nicht näher dargestellten, Drucktaste des Selbstverkäufers zu verschwenken.A lifting rod 17, on which a row of teeth 18 is formed, is also slidably mounted on the side wall 1. An indexing pawl 21 is arranged on an extension 19 of the carriage 12 so as to be pivotable about an axis 20. This is biased against the carriage 12 by means of a tension spring 22. It engages with one of the teeth 23 of the teeth row 18. The lifting rod 17 is adjustably connected to a lifting member 24. For this purpose, an elongated hole 25 running parallel to the lifting rod 17 is provided in the lifting member 24. The lifting rod 17 has 25 threaded bores 26 within the elongated hole, the spacing of which corresponds to the pitch width T. A screw 27 is screwed into one of the threaded bores 26 and does not lead to the rigid connection of the lifting rod 17 and lifting member 24. Rather, the screw 27 cooperates with the lower edge of the elongated hole 25 as a stop. At the bottom of the lifting member 24, an actuating lever 29 is mounted on an axis 30 on a pin 28. The actuating lever 29 can be pivoted by means of the push button of the self-seller which is assigned to this drop-down shaft and is not shown in detail.

An der Fortschaltklinke 21 ist ein Kupplungshebel 31 befestigt, der längs der Seitenwand 1 verläuft und vor der Seitenwand 1 einen Griff 32 aufweist. An dem Schlitten 12 ist eine Blattfeder 33 befestigt, die einen Bogen 34 aufweist und sich am Griff 32 abstützt. An jeder Klappe 3 ist gegenüber dem Finger 7 eine Rückstellschräge 35 ausgebildet, die im abgeklappten Zustand der Klappe 3 in die Bewegungsbahn des Bogens 34 ragt.A clutch lever 31 is fastened to the indexing pawl 21 and runs along the side wall 1 and has a handle 32 in front of the side wall 1. On the carriage 12, a leaf spring 33 is attached, which has an arc 34 and is supported on the handle 32. A reset bevel 35 is formed on each flap 3 relative to the finger 7 and projects into the movement path of the arc 34 when the flap 3 is folded down.

In den Fig. 1 und 2 ist der Schlitten 12 in einer Mittelstellung gezeigt, in der schon einige Klappen abgeworfen sind. Ausgehend von dieser Stellung ist die Funktionsweise der beschriebenen Einrichtung etwa folgende:

  • Wird der Betätigungshebel 29 verschwenkt, dann wird das Hubglied 24 angehoben. Da im Beispielsfalle die Fallklappen in der kleinstmöglichen Teilung angeordnet und dementsprechend die Schraube 27 in der entsprechenden Gewindebohrung 26 sitzt, erfolgt erst ein Leerhub zwischen dem Hubglied 24 und der Hubstange 17. Gegen Ende des Hubs des Hubgliedes 24 schlägt der untere Rand dessen Langloch 25 gegen die Schraube 27 so, daß danach die Hubstange 17 nach oben verschoben wird. Über die auf einem Zahn 18 aufsitzende Kuppe 23 wird die Fortschaltklinke 21 nach oben geschoben, wobei sie über die Achse 20 den Schlitten 12 mitnimmt. Die Auslenkschräge 15 der Nase 14 des Schlittens 12 verschwenkt dabei das Rastglied 9 so nach außen, daß der Finger 7 abfällt. Der Schlitten 12 läuft mit seinen Rollen 13 an den Schienen 10 und 11. Sobald der Schlitten 12 so weit angehoben ist, daß dessen Nase 14 das ausgelenkte Rastglied 9 freigibt, schnappt dieses unter den Anschlagrand 16, so daß der Schlitten 12 nicht mehr nach unten zurückweichen kann. Die Zugstange 17 kann dann wieder nach unten in ihre Ausgangsstellung zurückgehen. Unter der Wirkung der Feder 22 schnappt dann die Fortschaltklinke 21 über den nächstoberen Zahn 18. Diese Vorgänge wiederholen sich so oft bis auch die oberste Klappe ausgelöst ist. Die Bewegungen sind leichtgängig, da der Schlitten 12 nicht verkantet und nur wenige Teile bewegt werden müssen.
1 and 2, the carriage 12 is shown in a central position in which some flaps have already been thrown off. Starting from this position, the functioning of the described device is approximately as follows:
  • If the actuating lever 29 is pivoted, the lifting member 24 is raised. Since in the example the drop flaps are arranged in the smallest possible division and accordingly the screw 27 is seated in the corresponding threaded bore 26, there is only an idle stroke between the lifting member 24 and the lifting rod 17. Towards the end of the stroke of the lifting member 24, the lower edge strikes its elongated hole 25 the screw 27 so that the lifting rod 17 is then moved upwards. The indexing pawl 21 is pushed upward over the crest 23, which is seated on a tooth 18, and takes the carriage 12 with it over the axis 20. The deflection bevel 15 of the nose 14 of the carriage 12 pivots the latching member 9 so that the finger 7 falls off. The carriage 12 runs with its rollers 13 on the rails 10 and 11. As soon as the carriage 12 is raised so far that its nose 14 releases the deflected locking member 9, it snaps under the stop edge 16 so that the carriage 12 no longer downwards can recede. The pull rod 17 can then go back down to its starting position. Under the action of the spring 22, the indexing pawl 21 then snaps over the next upper tooth 18. These processes are repeated until the uppermost flap is triggered. The movements are smooth since the carriage 12 does not tilt and only a few parts have to be moved.

Beim nächstmaligen Befüllen des Schachts ist der Schlitten 12 wieder nach unten zurückzustellen und es sind die Klappen 3 wieder in ihre waagerechte Stapelstellung zu bringen. Es braucht hierfür nur der Griff 32 nach unten gedrückt zu werden. Dabei löst sich die Kuppe 23 von der Zahnreihe 18 und die Schräge 36 der Sperrklinke 21 schwenkt die Rastglieder 9 so unter dem Anschlagrand 16 weg, daß der Schlitten 12 nach unten gleiten kann. Gleichzeitig mit der Betätigung des Griffs 32 wird der Bogen 34 der Blattfeder 33 im Zuge des Nachuntenschiebens nacheinander gegen die Rückstellschrägen 35 so gedrückt, daß die Klappen in ihre waagerechte Stellung übergehen und mit ihren Fingern 7 auf den Rastgliedern 9 aufliegen. Durch die höhenversetzte Lage des Bogens 34 und der Schräge 36 ist gewährleistet, daß der Schlitten 12 leicht nach unten gleiten kann und dabei alle Klappen 3 zurückgestellt werden. Der Bogen 34 bringt dabei eine weiche Rückstellbewegung mit sich.The next time the shaft is filled, the carriage 12 is to be put back down and the flaps 3 are to be brought back into their horizontal stacking position. It is only necessary to push the handle 32 down. The crest 23 detaches from the row of teeth 18 and the bevel 36 of the pawl 21 pivots the locking members 9 under the stop edge 16 so that the carriage 12 can slide down. Simultaneously with the actuation of the handle 32, the sheet 34 of the leaf spring 33 is pressed one after the other against the restoring bevels 35 in the course of the downward sliding so that the flaps pass into their horizontal position and rest with their fingers 7 on the locking members 9. The height-offset position of the arc 34 and the bevel 36 ensures that the carriage 12 can slide down easily and all the flaps 3 are reset. The arch 34 brings with it a soft return movement.

Ersichtlich hängt der Bauaufwand nur wenig von der Anzahl der verwendeten Klappen 3 ab, da der Schlitten 12, die Fortschaltklinke 21 sowie der die Rastglieder 9 bildende Rechen nur einmal vorgesehen sein müssen. Die Hubhöhe der Hubstange 17 wächst nicht mit der Anzahl der Fächer. Vielmehr wird der Hub dann niedriger, wenn viele Fächer eingesetzt sind.Obviously, the construction effort depends only slightly on the number of flaps 3 used, since the slide 12, the indexing pawl 21 and the rake forming the latching members 9 only have to be provided once. The lifting height of the lifting rod 17 does not increase with the number of compartments. Rather, the stroke becomes lower if many compartments are used.

Der Fallklappenschacht läßt sich leicht für Fälle umrüsten, in denen die zu verkaufenden Waren eine größere Höhe haben als in der Teilungsbreite T unterzubringen sind. Es werden dann beispielsweise nur alle zweiten, dritten oder vierten Klappen in dem Schacht belassen. Die übrigen werden herausgenommen. Entsprechend wird die Schraube 27 verstellt. Zur Verstellung der Hubhöhe der Hubstange 17 kann auch an der Hubstange 17 eine höhenverstellbare Leiste vorgesehen sein, deren unterer Rand mit einem Anschlag der Seitenwand 1 so zusammenarbeitet, daß die Hubausgangsstellung tiefer oder höher liegt und damit der effektive Hub der Hubstange 17 bei einer Betätigung des Betätigungshebels 29 länger bzw. kürzer ist.The trap door can easily be converted for cases in which the goods to be sold have a greater height than can be accommodated in the division width T. Then, for example, only all of the second, third or fourth flaps are left in the shaft. The rest are taken out. The screw 27 is adjusted accordingly. To adjust the lifting height of the lifting rod 17, a height-adjustable bar can also be provided on the lifting rod 17, the lower edge of which cooperates with a stop of the side wall 1 in such a way that the initial stroke position is lower or higher and thus the effective stroke of the lifting rod 17 when the Actuating lever 29 is longer or shorter.
