Definitions

  • the invention relates to a device for transporting closure caps in vascular closure machines according to the preamble of claim 1.
  • Such a device is already known, in which the drivers are formed by the beveled teeth of a star wheel and the transport device has a conveyor belt running radially to the axis of rotation of this star wheel (DE-OS 21 47 770). At the end of the conveyor channel there is a slideway at the periphery of the star wheel with a side guide rail for the caps.
  • caps can easily be crushed between the star wheel and the beginning of the guide bar if the conveyor belt does not feed the caps quickly enough. The operational security is therefore low; the achievable performance is limited.
  • the drivers are formed by radially projecting cams of a round disk and the Transport device has a magnet arranged opposite the end region of the conveying channel with a stop limiting the depth of penetration of the caps into the orbit of the drivers (DE-OS 27 34 599).
  • the caps torn away from the stop by the carriers are initially fixed exclusively to the disk by further magnets before they are gripped by the fixed guide strip of a slideway formed on the periphery of the disk for the caps.
  • the gap formed in this way between the end region of the conveying channel and the beginning region of the guide bar is intended to separate deformed corks.
  • the invention has for its object to eliminate the risk of crushing caps in a generic device for transporting caps and thereby increase operational safety and performance. In addition, direct loading of sealing heads should be possible.
  • the caps already sit between the guide elements of the guide trough at the moment of the engagement of the drivers and can therefore no longer deflect sideways, tilt or be crushed.
  • the path from the exit of the conveyor channel into the guide trough is extremely short and can therefore be traversed quickly enough, even with the highest performance.
  • the drivers can hit the caps at a very high speed.
  • the achievable performance is therefore correspondingly high.
  • With medium and higher power the caps hardly come to rest before the attack of the driver concerned; at low outputs it is possible that the caps must be held briefly between the guide elements until the driver concerned arrives.
  • the cap waiting for its driver serves simultaneously as a stop for the next cap. This enables a particularly simple construction.
  • the transport device there are various options for the formation of the transport device. This can e.g. be formed by a small turntable on which the caps rest.
  • the construction of the transport device made of magnets specified in claims 8 to 11 is particularly advantageous. This enables, on the one hand, a particularly reliable transport of the caps, which must be able to be influenced magnetically, and, on the other hand, a particularly compact and easy-to-clean construction.
  • the drivers can be formed, for example, by the radially protruding teeth of a star wheel, which feeds the caps to the circumferential sealing heads of the vessel sealing machine. It is particularly expedient if the drivers are cam-like or pin-like and are arranged directly on the circumferential sealing heads of the vessel sealing machine. As a result, a rotating star wheel or the like can be completely dispensed with. This is made possible by the exact initial guidance of the caps between the guide elements.
  • the device according to FIGS. 1 and 2 is integrated into a vessel closure machine, only partially shown, in which closure caps 1 in the form of crown caps, hereinafter referred to as caps 1 for short, are attached to beverage bottles, not shown.
  • the device has a conveying channel 2 coming from a cap magazine (not shown) with agitator and turning tube, which accommodates the caps 1 in a single row and lying next to one another in the desired position of use with slight play.
  • the conveying channel 2 initially runs vertically and in its lower region merges approximately horizontally into an arc. It has an exactly horizontal end region 3 which is formed in a metallic guide plate 10, while its remaining region is formed by a U-rail with screwed-on cover strips.
  • the caps 1 are transported in the conveying channel 2 by gravity and, in particular in the case of higher power, additionally by blowing nozzles (not shown) at high speed to the end region 3 or the opening there.
  • a guide channel 6 for the caps 1 adjoins the end region 3 of the conveying channel 2 in the same horizontal plane.
  • the guide trough 6 is worked into the horizontal guide plate 10 in the same way as the trough-like end region 3 and has two lateral guide elements 7a, 7b for the caps 1 in the form of vertical edges.
  • the bottom of the guide trough 6 is by a Guide plate 10 formed horizontal sliding surface 8, which extends seamlessly into the end region 3 of the conveyor channel 2 and ends at the U-rail.
  • a plurality of cam-shaped carriers 4 run past the end region 3 essentially at its height, transversely to the direction of movement of the caps 1 in the conveying channel 2, indicated by an arrow. These are arranged on the underside of closing heads 14 which can be raised and lowered in a controlled manner in a rotor 15 with a vertical axis of rotation and run continuously with them on a circular path denoted by 16 in the direction of the arrow.
  • the guide trough 6 with its guide elements 7a, 7b seated on both sides of the circular path 16 is adapted to the circular path 16 of the drivers 4 in such a way that they always engage the caps 1 exactly in the center. Accordingly, the guide channel 6 runs in its initial area almost at right angles to the end area 3 of the conveying channel 2 and extends in the circumferential direction of the driver 4.
  • the guide element 7a on the conveying channel 2 side passes over a slight rounding 17 directly into the adjacent guiding surface of the end area 3 .
  • the other guide element 7b is extended beyond the guide element 7a against the direction of rotation of the catches 4 into the space lying opposite the end region 3 and forms a safety stop there for the caps 1 emerging from the conveying channel 2.
  • plate-shaped hold-down devices 9a, 9b, 9c are screwed onto the guide plate 10, which only overlap the edge of the caps 1 with play. Sufficient engagement space thus remains for the drivers 4, which sweep over the sliding surface 8 at a short distance.
  • the plate-shaped hold-down devices 9a, 9b, 9c can be adapted to the roundness and the diameter of the caps 1 such that they additionally take over the lateral guidance of the caps 1, either together with the guide elements of the end region 3 and the guide elements 7a, 7b of the guide channel 6 or even alone if these guide elements are undercut accordingly. In this case, there is a particularly low-friction transition of the caps from the delivery channel 2 into the guide trough 6 and extremely little wear on the guide elements, since these do not come into contact with the sharp edges of the caps 1.
  • a transport device 5 consisting of two permanent magnets 11 and 12 of different strengths, is provided. Both permanent magnets 11, 12 are attached to the underside of the guide plate 10 at a short distance from the sliding surface 8.

  • the Permanent magnet 12 is approximately twice as strong as permanent magnet 11.
  • the foremost cap 1 in the end region 3 of the conveying channel 2 is pulled out of the conveying device 5 and moved around the rounding 17 into the conveying trough 6 or between its guide elements 7a, 7b and the hold-down devices 9a, 9b, and just over half of their area, so that they are in the range of their max. Width or their diameter is exactly between the guide elements 7a, 7b or hold-down 9a, 9b.
  • the magnetic force is such that the cap 1 is held in this position until it is entrained by the driver 4 in question and is moved further in the direction of the arrow through the guide groove 6.
  • the cap immediately following which is located in the end region 3 of the conveying channel 2
  • the fixed cap 1 is held by the fixed cap 1 against the supply force of the caps 1 in the conveying channel 2 outside the orbit 16 of the carriers 4.
  • the next cap 1 moves up accordingly.
  • the above-described function of the two permanent magnets 11, 12 can also be achieved by a large number of smaller, equally strong permanent magnets 13 if they are fastened to the guide plate 10 in the arrangement shown in FIG. 3, just below the sliding surface 8.

Description

Die Erfindung betrifft eine Vorrichtung zum Transportieren von Verschlußkappen in Gefäßverschließmaschinen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for transporting closure caps in vascular closure machines according to the preamble of claim 1.

Es ist bereits eine derartige Vorrichtung bekannt, bei der die Mitnehmer durch die abgeschrägten Zähne eines Sternrads gebildet werden und die Transporteinrichtung ein radial zur Drehachse dieses Sternrads verlaufendes Förderband aufweist (DE-OS 21 47 770). An den Endbereich des Förderkanals schließt sich eine am Unfang des Sternrads verlaufende Gleitbahn mit einer seitlichen Führungsleiste für die Kappen an. Bei dieser bekannten Vorrichtung können leicht Kappen zwischen dem Sternrad und dem Anfang der Führungsleiste zerquetscht werden, wenn das Förderband die Kappen nicht schnell genug zufördert. Die Betriebssicherheit ist daher gering; die erzielbare Leistung ist beschränkt.Such a device is already known, in which the drivers are formed by the beveled teeth of a star wheel and the transport device has a conveyor belt running radially to the axis of rotation of this star wheel (DE-OS 21 47 770). At the end of the conveyor channel there is a slideway at the periphery of the star wheel with a side guide rail for the caps. In this known device, caps can easily be crushed between the star wheel and the beginning of the guide bar if the conveyor belt does not feed the caps quickly enough. The operational security is therefore low; the achievable performance is limited.

Bei einer anderen bekannten Vorrichtung der eingangs genannten Art werden die Mitnehmer durch radial vorstehende Nocken einer runden Scheibe gebildet und die Transporteinrichtung weist einen gegenüber dem Endbereich des Förderkanals angeordneten Magneten mit einem die Eindringtiefe der Kappen in die Umlaufbahn der Mitnehmer begrenzenden Anschlag auf (DE-OS 27 34 599). Die von den Mitnehmern vom Anschlag weggerissenen Kappen werden zunächst ausschließlich durch weitere Magneten an der Scheibe fixiert, bevor sie von der feststehenden Führungsleiste einer am Umfang der Scheibe ausgebildeten Gleitbahn für die Kappen erfaßt werden. Durch die so gebildete Lücke zwischen dem Endbereich des Förderkanals und dem Anfangsbereich der Führungsleiste sollen deformierte Korken ausgeschieden werden. Auch hier besteht die Gefahr des Zerquetschens von Korken zwischen den Mitnehmern und dem vorderen Rand der Führungsleiste, da diese durch die Magneten nur ungenügend geführt werden können.In another known device of the type mentioned, the drivers are formed by radially projecting cams of a round disk and the Transport device has a magnet arranged opposite the end region of the conveying channel with a stop limiting the depth of penetration of the caps into the orbit of the drivers (DE-OS 27 34 599). The caps torn away from the stop by the carriers are initially fixed exclusively to the disk by further magnets before they are gripped by the fixed guide strip of a slideway formed on the periphery of the disk for the caps. The gap formed in this way between the end region of the conveying channel and the beginning region of the guide bar is intended to separate deformed corks. Here, too, there is a risk of corks being crushed between the drivers and the front edge of the guide bar, since these cannot be adequately guided by the magnets.

Bei beiden bekannten Vorrichtungen erfolgt die Beschickung der mit Haltemagneten für die Kappen versehenen Verschließköpfe indirekt unter Zwischenschaltung des Sternrads bzw. der Scheibe und der ortsfesten Gleitbahnen und Führungsleisten. Dies führt zu einer aufwendigen Bauweise.In both known devices, the loading of the closing heads provided with holding magnets for the caps takes place indirectly with the interposition of the star wheel or the disk and the stationary slideways and guide strips. This leads to a complex construction.

Der Erfindung liegt die Aufgabe zugrunde, bei einer gattungsgemäßen Vorrichtung zum Transportieren von Verschlußkappen die Gefahr des Zerdrückens von Kappen zu beseitigen und dadurch die Betriebssicherheit und die Leistung zu erhöhen. Außerdem soll eine direkte Beschickung von Verschließköpfen möglich sein.The invention has for its object to eliminate the risk of crushing caps in a generic device for transporting caps and thereby increase operational safety and performance. In addition, direct loading of sealing heads should be possible.

Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.

Bei einer erfindungsgemäßen Vorrichtung sitzen die Verschlußkappen im Augenblick des Angriffs der Mitnehmer bereits zwischen den Leitelementen der Führungsrinne und können somit nicht mehr seitlich ausweichen, sich verkanten oder zerquetscht werden. Der Weg vom Ausgang des Förderkanals in die Führungsrinne ist extrem kurz und kann daher auch bei höchsten Leistungen schnell genug durchfahren werden. Die Mitnehmer können mit sehr hoher Geschwindigkeit auf die Verschlußkappen auftreffen. Die erzielbare Leistung ist daher entsprechend hoch. Bei mittlerer und höherer Leistung kommen die Verschlußkappen vor dem Angriff des betreffenden Mitnehmers kaum zur Ruhe; bei niedrigen Leistungen ist es möglich, daß die Verschlußkappen kurzzeitig zwischen den Leitelementen festgehalten werden müssen, bis der betreffende Mitnehmer eintrifft.In a device according to the invention, the caps already sit between the guide elements of the guide trough at the moment of the engagement of the drivers and can therefore no longer deflect sideways, tilt or be crushed. The path from the exit of the conveyor channel into the guide trough is extremely short and can therefore be traversed quickly enough, even with the highest performance. The drivers can hit the caps at a very high speed. The achievable performance is therefore correspondingly high. With medium and higher power, the caps hardly come to rest before the attack of the driver concerned; at low outputs it is possible that the caps must be held briefly between the guide elements until the driver concerned arrives.

Ein besonders exakter und schneller Transfer der Kappen zwischen dem Förderkanal und der Führungsrinne wird durch die in den Ansprüchen 2 bis 6 angegebenen Weiterbildungen der erfindungsgemäßen Vorrichtung erzielt.A particularly precise and rapid transfer of the caps between the conveying channel and the guide trough is achieved by the developments of the device according to the invention specified in claims 2 to 6.

Besonders vorteilhaft ist es ferner, wenn gemäß der im Anspruch 7 niedergelegten Weiterbildung die jeweils auf ihren Mitnehmer wartende Kappe gleichzeitig als Anschlag für die nächstfolgende Kappe dient. Dies ermöglicht eine besonders einfache Bauweise.It is furthermore particularly advantageous if, in accordance with the development set out in claim 7, the cap waiting for its driver serves simultaneously as a stop for the next cap. This enables a particularly simple construction.

Für die Ausbildung der Transporteinrichtung gibt es verschiedene Möglichkeiten. Diese kann z.B. durch eine kleine Drehscheibe gebildet werden, auf der die Kappen aufliegen. Besonders vorteilhaft ist der in den Ansprüchen 8 bis 11 angegebene Aufbau der Transporteinrichtung aus Magneten. Hierdurch wird einerseits ein besonders zuverlässiger Transport der Kappen, die magnetisch beeinflußbar sein müssen, und andererseits ein besonders kompakter und leicht zu reinigender Aufbau ermöglicht.There are various options for the formation of the transport device. This can e.g. be formed by a small turntable on which the caps rest. The construction of the transport device made of magnets specified in claims 8 to 11 is particularly advantageous. This enables, on the one hand, a particularly reliable transport of the caps, which must be able to be influenced magnetically, and, on the other hand, a particularly compact and easy-to-clean construction.

Die Mitnehmer können beispielsweise durch die radial abstehenden Zähne eines Sternrads gebildet werden, welches die Kappen den umlaufenden Verschließköpfen der Gefäßverschließmaschine zuführt. Besonders zweckmäßig ist es, wenn die Mitnehmer gemäß den Ansprüchen 12 und 13 nocken- oder stiftartig ausgebildet und direkt an den umlaufenden Verschließköpfen der Gefäßverschließmaschine angeordnet sind. Hierdurch kann auf ein umlaufendes Sternrad oder dgl. vollständig verzichtet werden. Dies wird möglich durch die exakte anfängliche Führung der Kappen zwischen den Leitelementen.The drivers can be formed, for example, by the radially protruding teeth of a star wheel, which feeds the caps to the circumferential sealing heads of the vessel sealing machine. It is particularly expedient if the drivers are cam-like or pin-like and are arranged directly on the circumferential sealing heads of the vessel sealing machine. As a result, a rotating star wheel or the like can be completely dispensed with. This is made possible by the exact initial guidance of the caps between the guide elements.

Two exemplary embodiments of the invention are described below with reference to the drawings. Show it:

Die Vorrichtung nach Fig. 1 und 2 ist in eine nur teilweise dargestellte Gefäßverschließmaschine integriert, in der Verschlußkappen 1 in Form von Kronenkorken, im nachstehenden kurz Kappen 1 genannt, an nicht gezeigten Getränkeflaschen befestigt werden. Die Vorrichtung weist einen von einem nicht gezeigten Kappenmagazin mit Rührwerk und Wenderohr kommenden Förderkanal 2 auf, der die Kappen 1 einreihig und nebeneinander liegend in der gewünschten Gebrauchslage mit leichtem Spiel aufnimmt. Der Förderkanal 2 verläuft anfänglich senkrecht und geht in seinem unteren Bereich bogenförmig annähernd in die Horizontale über. Er besitzt einen exakt horizontal verlaufenden Endbereich 3, der in einer metallischen Führungsplatte 10 ausgebildet ist, während sein übriger Bereich durch eine U-Schiene mit aufgeschraubten Deckleisten gebildet wird. Die Kappen 1 werden im Förderkanal 2 durch die Schwerkraft und, insbesondere bei höherer Leistung, zusätzlich durch nicht gezeigte Blasdüsen mit hoher Geschwindigkeit zum Endbereich 3 bzw. der dort vorhandenen Öffnung transportiert.The device according to FIGS. 1 and 2 is integrated into a vessel closure machine, only partially shown, in which closure caps 1 in the form of crown caps, hereinafter referred to as caps 1 for short, are attached to beverage bottles, not shown. The device has a conveying channel 2 coming from a cap magazine (not shown) with agitator and turning tube, which accommodates the caps 1 in a single row and lying next to one another in the desired position of use with slight play. The conveying channel 2 initially runs vertically and in its lower region merges approximately horizontally into an arc. It has an exactly horizontal end region 3 which is formed in a metallic guide plate 10, while its remaining region is formed by a U-rail with screwed-on cover strips. The caps 1 are transported in the conveying channel 2 by gravity and, in particular in the case of higher power, additionally by blowing nozzles (not shown) at high speed to the end region 3 or the opening there.

Unmittelbar an den Endbereich 3 des Förderkanals 2 schließt sich in gleicher horizontaler Ebene eine Führungsrinne 6 für die Kappen 1 an. Die Führungsrinne 6 ist in gleicher Weise wie der rinnenartige Endbereich 3 in die horizontale Führungsplatte 10 eingearbeitet und besitzt zwei seitliche Leitelemente 7a, 7b für die Kappen 1 in Form von senkrechten Kanten. Der Boden der Führungsrinne 6 wird durch eine an der Führungsplatte 10 ausgebildete horizontale Gleitfläche 8 gebildet, die sich nahtlos bis in den Endbereich 3 des Förderkanals 2 erstreckt und an dessen U-Schiene endet.A guide channel 6 for the caps 1 adjoins the end region 3 of the conveying channel 2 in the same horizontal plane. The guide trough 6 is worked into the horizontal guide plate 10 in the same way as the trough-like end region 3 and has two lateral guide elements 7a, 7b for the caps 1 in the form of vertical edges. The bottom of the guide trough 6 is by a Guide plate 10 formed horizontal sliding surface 8, which extends seamlessly into the end region 3 of the conveyor channel 2 and ends at the U-rail.

Wie die Fig. 1 zeigt, laufen dicht vor dem Endbereich 3 im wesentlichen auf dessen Höhe quer zu der durch einen Pfeil angedeuteten Bewegungsrichtung der Kappen 1 im Förderkanal 2 mehrere nockenförmige Mitnehmer 4 vorbei. Diese sind an der Unterseite von gesteuert heb- und senkbar in einem Rotor 15 mit senkrechter Drehachse gelagerten Verschließköpfen 14 angeordnet und laufen mit diesen kontinuierlich auf einer mit 16 bezeichneten Kreisbahn in Pfeilrichtung um.As shown in FIG. 1, a plurality of cam-shaped carriers 4 run past the end region 3 essentially at its height, transversely to the direction of movement of the caps 1 in the conveying channel 2, indicated by an arrow. These are arranged on the underside of closing heads 14 which can be raised and lowered in a controlled manner in a rotor 15 with a vertical axis of rotation and run continuously with them on a circular path denoted by 16 in the direction of the arrow.

Die Führungsrinne 6 mit ihren beiderseits der Kreisbahn 16 sitzenden Leitelementen 7a, 7b ist der Kreisbahn 16 der Mitnehmer 4 derart angepaßt, daß diese immer exakt mittig an den Kappen 1 angreifen. Dementsprechend verläuft die Führungsrinne 6 in ihrem Anfangsbereich nahezu rechtwinklig zum Endbereich 3 des Förderkanals 2 und erstreckt sich in Umlaufrichtung der Mitnehmer 4. Dabei geht das auf Seite des Förderkanals 2 befindliche Leitelement 7a über eine leichte Abrundung 17 direkt in die benachbarte Leitfläche des Endbereichs 3 über. Das andere Leitelement 7b dagegen ist über das Leitelement 7a hinaus entgegen der Umlaufrichtung der Mitnehmer 4 bis in den gegenüber dem Endbereich 3 liegenden Raum verlängert und bildet dort einen Sicherheitsanschlag für die aus dem Förderkanal 2 austretenden Kappen 1. Um ein Hochsteigen der Kappen 1 im Transferbereich zwischen dem Endbereich 3 und der Führungsrinne 6 zu verhindern, sind auf der Führungsplatte 10 plättchenförmige Niederhalter 9a, 9b, 9c angeschraubt, die nur den Rand der Kappen 1 mit Spiel übergreifen. Es verbleibt somit ausreichend Eingriffsraum für die Mitnehmer 4, die mit geringem Abstand über die Gleitfläche 8 hinwegstreichen.The guide trough 6 with its guide elements 7a, 7b seated on both sides of the circular path 16 is adapted to the circular path 16 of the drivers 4 in such a way that they always engage the caps 1 exactly in the center. Accordingly, the guide channel 6 runs in its initial area almost at right angles to the end area 3 of the conveying channel 2 and extends in the circumferential direction of the driver 4. The guide element 7a on the conveying channel 2 side passes over a slight rounding 17 directly into the adjacent guiding surface of the end area 3 . The other guide element 7b, on the other hand, is extended beyond the guide element 7a against the direction of rotation of the catches 4 into the space lying opposite the end region 3 and forms a safety stop there for the caps 1 emerging from the conveying channel 2. In order to climb the caps 1 in the transfer area between the end area 3 and the To prevent the guide trough 6, plate-shaped hold-down devices 9a, 9b, 9c are screwed onto the guide plate 10, which only overlap the edge of the caps 1 with play. Sufficient engagement space thus remains for the drivers 4, which sweep over the sliding surface 8 at a short distance.

Die plättchenförmigen Niederhalter 9a, 9b, 9c können derart an die Rundung und den Durchmesser der Kappen 1 angepaßt sein, daß sie zusätzlich die seitliche Führung der Kappen 1 übernehmen, entweder zusammen mit den Leitelementen des Endbereichs 3 und den Leitelementen 7a, 7b der Führungsrinne 6 oder auch allein, wenn diese Leitelemente entsprechend hinterschnitten sind. In diesem Falle ergibt sich ein besonders reibungsarmer Übergang der Kappen vom Förderkanal 2 in die Führungsrinne 6 und ein äußerst geringer Verschleiß an den Leitelementen, da diese nicht mit den scharfen Rändern der Kappen 1 in Berührung kommen.The plate-shaped hold-down devices 9a, 9b, 9c can be adapted to the roundness and the diameter of the caps 1 such that they additionally take over the lateral guidance of the caps 1, either together with the guide elements of the end region 3 and the guide elements 7a, 7b of the guide channel 6 or even alone if these guide elements are undercut accordingly. In this case, there is a particularly low-friction transition of the caps from the delivery channel 2 into the guide trough 6 and extremely little wear on the guide elements, since these do not come into contact with the sharp edges of the caps 1.

Im Transferbereich der Kappen 1 zwischen dem Endbereich 3 des Förderkanals 2 und der Führungsrinne 6 ist eine Transporteinrichtung 5, bestehend aus zwei unterschiedlich starken Dauermagneten 11 und 12, vorgesehen. Beide Dauermagneten 11, 12 sind an der Unterseite der Führungsplatte 10 mit geringem Abstand zur Gleitfläche 8 befestigt. Der schwächere Dauermagnet 11 liegt genau gegenüber dem Endbereich 3 bzw. dessen Öffnung; der stärkere Dauermagnet 12 schließt sich in Transportrichtung seitlich an und sitzt im Anfangsbereich der Förderrinne 6 leicht zu deren vom Förderkanal 2 abgewandten Seite hin versetzt. Der Dauermagnet 12 ist in etwa doppelt so stark wie der Dauermagnet 11.In the transfer area of the caps 1 between the end area 3 of the conveying channel 2 and the guide channel 6, a transport device 5, consisting of two permanent magnets 11 and 12 of different strengths, is provided. Both permanent magnets 11, 12 are attached to the underside of the guide plate 10 at a short distance from the sliding surface 8. The weaker permanent magnet 11 lies exactly opposite the end region 3 or its opening; the stronger permanent magnet 12 adjoins laterally in the direction of transport and sits in the start region of the conveyor trough 6 slightly offset toward its side facing away from the conveyor channel 2. The Permanent magnet 12 is approximately twice as strong as permanent magnet 11.

Durch die Transporteinrichtung 5 wird die jeweils vorderste Kappe 1 im Endbereich 3 des Förderkanals 2 aus diesem herausgezogen und um die Abrundung 17 herum in die Förderrinne 6 bzw. zwischen deren Leitelemente 7a, 7b und die Niederhalter 9a, 9b hineinbewegt und zwar etwas über die Hälfte ihrer Fläche, so daß sie im Bereich ihrer max. Breite bzw. ihres Durchmessers exakt zwischen den Leitelementen 7a, 7b bzw. Niederhaltern 9a, 9b geführt ist. Die Magnetkraft ist derart bemessen, daß die Kappe 1 in dieser Position gehalten wird, bis sie vom betreffenden Mitnehmer 4 mitgerissen und in Pfeilrichtung durch die Führungsrinne 6 weiterbewegt wird. Gleichzeitig wird durch die fixierte Kappe 1 die unmittelbar nachfolgende Kappe, die sich im Endbereich 3 des Förderkanals 2 befindet, entgegen der Nachschubkraft der Kappen 1 im Förderkanal 2 außerhalb der Umlaufbahn 16 der Mitnehmer 4 gehalten. Sobald die fixierte Kappe 1 durch ihren Mitnehmer 4 entfernt worden ist, rückt die nächste Kappe 1 entsprechend nach.The foremost cap 1 in the end region 3 of the conveying channel 2 is pulled out of the conveying device 5 and moved around the rounding 17 into the conveying trough 6 or between its guide elements 7a, 7b and the hold-down devices 9a, 9b, and just over half of their area, so that they are in the range of their max. Width or their diameter is exactly between the guide elements 7a, 7b or hold-down 9a, 9b. The magnetic force is such that the cap 1 is held in this position until it is entrained by the driver 4 in question and is moved further in the direction of the arrow through the guide groove 6. At the same time, the cap immediately following, which is located in the end region 3 of the conveying channel 2, is held by the fixed cap 1 against the supply force of the caps 1 in the conveying channel 2 outside the orbit 16 of the carriers 4. As soon as the fixed cap 1 has been removed by its driver 4, the next cap 1 moves up accordingly.

Die vorbeschriebene Funktion der beiden Dauermagneten 11, 12 kann auch durch eine Vielzahl von kleineren, gleich starken Dauermagneten 13 erzielt werden, wenn sie in der in Fig. 3 gezeigten Anordnung dicht unterhalb der Gleitfläche 8 an der Führungsplatte 10 befestigt sind.The above-described function of the two permanent magnets 11, 12 can also be achieved by a large number of smaller, equally strong permanent magnets 13 if they are fastened to the guide plate 10 in the arrangement shown in FIG. 3, just below the sliding surface 8.

Die von den Mitnehmern 4 durch die Führungsrinne 6 geschobenen Kappen 1 werden anschließend durch die an der unteren Stirnseite der Verschließköpfe 14 angeordneten Dauermagneten 18 übernommen und dann zusammen mit den Verschließköpfen 14 auf die zu verschließenden Getränkeflaschen abgesenkt und dort in der üblichen Weise durch Umbördeln befestigt.The pushed by the drivers 4 through the guide channel 6 caps 1 are then by the arranged below the end face of the closing heads 14 arranged permanent magnets 18 and then lowered together with the closing heads 14 onto the beverage bottles to be closed and fastened there in the usual manner by flanging.

Claims (15)

  1. Device for transporting sealing caps in vessel sealing machines with a conveying channel (2) which delivers the caps adjacent to each other in a row, drivers (4) for the caps which travel past the end region (3) of the channel (2) in a transverse direction on a closed path, as well as with a transport device (5) which moves the caps from the end region of the conveying channel into the path of the drivers, characterised in that directly adjoining the end region (3) of the conveying channel (2) in the direction of movement of the drivers (4) is a guide trough (6) for the caps with guide elements (7a, 7b) extending on both sides of the path of the drivers (4), and in that the transport device (5) is constructed in such a way that it introduces the cap which is foremost at any given time before arrival of the associated driver (4) from the end region (3) of the conveying channel (2) at least partially between the guide elements (7a, 7b) and if necessary holds it there fast until arrival of the driver (4).
  2. Device according to claim 1, characterised in that the end region (3) of the conveying channel (2) and the guide trough (6) lie in a common plane and are connected to each other by a slide surface (8) for the caps.
  3. Device according to claim 2, characterised in that the common plane is arranged horizontally and in that in the end region (3) of the conveying channel (2) and/or in the initial region of the guide trough (6) are provided hold-down devices (9a, 9b, 9c) for the caps.
  4. Device according to any of claims 1 to 3, characterised in that the guide element (7a) located on the side of the conveying channel (2) merges via a rounded portion with the adjacent side boundary of the end region (3) of the conveying channel (2).
  5. Device according to any of claims 2 to 4, characterised in that the end region (3) of the conveying channel (2), the guide trough (6) with the guide elements (7a, 7b), the slide surface (8) and if occasion arises the hold-down devices (9a, 9b, 9c) are formed or arranged on a common guide plate (10).
  6. Device according to any of claims 1 to 5, characterised in that the guide element (7b) arranged on the side of the path of the drivers (4) facing away from the conveying channel (2) extends opposite the direction of movement of the drivers (4) into the region opposite the end region (3) of the conveying channel (2) and forms a stop for the caps emerging from the conveying channel (2).
  7. Device according to any of claims 1 to 6, characterised in that the transport device (5) is constructed in such a way that a cap moved by it between the guide elements (7a, 7b) keeps the next cap, which is still located in the end region (3) of the conveying channel (2), outside the path of the drivers (4).
  8. Device according to any of claims 1 to 7, characterised in that the transport device (5) comprises at least one magnet (11, 12, 13).
  9. Device according to claim 8, characterised in that the transport device (5) comprises two permanent magnets of different strength, of which the weaker permanent magnet (11) is arranged opposite the end region (3) of the conveying channel (2) and the stronger permanent magnet (12) adjoining it in the initial region of the guide trough (6).
  10. Device according to claim 8, characterised in that the transport device (5) comprises a plurality of permanent magnets (13) of equal strength which are distributed in the end region (3) of the conveying channel (2) and adjoining it in the initial region of the guide trough (6).
  11. Device according to claim 2 and any of claims 8 to 10, characterised in that the magnets (11, 12, 13) are arranged close beneath the slide surface (8).
  12. Device according to any of claims 1 to 11, characterised in that each driver (4) is of cam-like or pin-like construction and engages between the guide elements (7a, 7b) at right angles to the plane of movement of the caps.
  13. Device according to claim 12, characterised in that the drivers (4) are arranged on the rotating sealing heads (14) of the vessel sealing machine, extending downwardly into the guide trough (6).
  14. Device according to any of claims 1 to 13, characterised in that the transport device (5) introduces the caps slightly more than half between the guide elements (7a, 7b), so that they sit with their broadest region in the guide trough (6).
  15. Device according to any of claims 3 to 14, characterised in that the hold-down devices (9a, 9b, 9c) take over lateral guiding of the caps.
