Description

Technisches GebietTechnical area

Die Erfindung betrifft ein System nach dem Oberbegriff des Änspruchs 1.The invention relates to a system according to the preamble of Änspruchs first

Stand der TechnikState of the art

Konventionelle Transportsysteme für Schachteln basieren meist auf Schachtelträgem mit mechanischer Klemmung der Schachteln. Die Träger können jeweils ein Schachtelformat bzw. einen Packstil transportieren, und die Umstellung auf neue Formate ist mit einem erheblichen Zeitaufwand verbunden. Oft müssen zudem formatspezifische Teile der mechanischen Schachtelhalterungen ausgetauscht werden. Diese Eingriffe bedeuten einen Produktionsausfall durch Stillstand der Maschine und bergen das Potential von Fehlern bei der Einrichtung oder Einstellung, was vor allem in der Pharmaindustrie problematisch ist. Dabei ist die Einrichtzeit bei Varianten mit austauschbaren Schachtelträgern besonders hoch, während blosse Einstellungen zwar einen geringeren Zeitbedarf erfordern, jedoch ein hohes Fehlerpotential beinhalten. Ein weiterer Nachteil, Schachteln mechanisch durch Klemmung zu halten, ist die hierbei unvermeidbar auftretende Deformation der Schachtel, die ein Verschliessen der Schachtel, während sie vom Schachtelträger gehalten wird, erschwert.Conventional carton transport systems are usually based on box carriers with mechanical clamping of the cartons. The carriers can each transport a box format or a packing style, and the conversion to new formats is associated with a considerable amount of time. In addition, format-specific parts of the mechanical box holders often have to be replaced. These interventions mean a loss of production due to the stoppage of the machine and have the potential for mistakes in setting up or adjusting, which is problematic especially in the pharmaceutical industry. The setup time for variants with exchangeable box carriers is particularly high, while mere adjustments require less time, but involve a high potential for error. Another disadvantage of mechanically holding boxes by clamping is the unavoidable deformation of the box, which makes it difficult to close the box while it is being held by the box carrier.

Als universell einsetzbare Alternative zu den Schachtelträgern mit mechanischer Klemmung sind Vakuumbänder bekannt, welche verschiedene Schachtelformate ohne Umstellung verarbeiten können. Vakuumbänder zeichnen sich jedoch durch geringe Genauigkeit und Haltekräfte aus und können ein unbeabsichtigtes Verschieben der Schachtel beim Transport nicht zuverlässig verhindern. Sie sind daher insbesondere für Anwendung im Pharmabereich nicht geeignet sind.As a universally applicable alternative to the box carriers with mechanical Clamping Vacuum bands are known which can handle different box formats without conversion. Vacuum bands, however, are characterized by low accuracy and holding forces and can not reliably prevent unintentional movement of the box during transport. They are therefore not suitable in particular for use in the pharmaceutical sector.

Ein Schachtelträger der eingangs genannten Art ist in DE 10 2006 008 646 A1 offenbart.A box carrier of the type mentioned is in DE 10 2006 008 646 A1 disclosed.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, einen Schachtelträger der eingangs genannten Art zu schaffen, der die vorgenannten Nachteile nicht aufweist.The invention has for its object to provide a box carrier of the type mentioned, which does not have the aforementioned disadvantages.

Ein weiteres Ziel der Erfindung ist die Bereitstellung eines Schachtelträgers für den Transport von Schachteln zur Verpackung insbesondere pharmazeutischer Produkte in einer Verpackungsmaschine.Another object of the invention is to provide a carton carrier for transporting cartons for packaging, in particular, pharmaceutical products in a packaging machine.

Zur erfindungsgemässen Lösung der Aufgabe führt ein Schachtelträger mit den Merkmalen des Änspruchs 1.For solving the problem according to the invention, a box carrier carries the features of claim 1.

Die Anordnung von Saugöffnungen in der Anlagefläche bietet folgende Vorteile:

  • Es sind keine Formatumstellungen bei unterschiedlichen Schachtelformaten erforderlich.
  • Der Träger ist für Hülsen und für Flachzuschnitte gleichermassen geeignet.
  • Sichererer Halt durch hohe Haltekräfte und sichere Positionierung der Schachteln, da kein Verschieben im Träger möglich.
  • Keine Deformation der Schachteln durch Haltekräfte.
  • Gute Zugänglichkeit, die Schachtel wird im wesentlichen nur von einer Seite gehalten, während die anderen Seiten im wesentlichen frei zugänglich sind.
  • Die Schachtel kann verschlossen werden, während sie sich im Schachtelträger befindet, da sie nicht deformiert wird.
  • Die gute Zugänglichkeit erleichtert das Bedrucken / Codieren der Schachtel und vergleichbare Operationen.
  • Hohe Sicherheit, da nicht anfällig für Fehlmanipulationen.
The arrangement of suction openings in the contact surface offers the following advantages:
  • There are no format changes required for different box formats.
  • The carrier is equally suitable for sleeves and flat blanks.
  • Safer hold due to high holding forces and secure positioning of the boxes, as no movement in the carrier is possible.
  • No deformation of the boxes due to holding forces.
  • Good accessibility, the box is held substantially only from one side, while the other sides are essentially freely accessible.
  • The box can be closed while it is in the box carrier because it is not deformed.
  • Good accessibility facilitates box printing / coding and similar operations.
  • High security, as not susceptible to mistreatment.

Das Ansaugen der Schachteln mittels Vakuum hat entscheidende Vorteile bezüglich Ergonomie und Formatanpassung. Die gute Ergonomie und die einfache Bedienbarkeit sind die Hauptvorteile bei dem Einsatz der erfindungsgemässen Lösung. Die Stillstandszeit der Maschine für die Formatumstellung wird verkürzt, und mögliche Fehlerquellen werden auf ein Minimum reduziert. Wesentlich ist auch die Tatsache, dass keine besonderen Kenntnisse des Bedieners für die Formatumstellung notwendig sind.The suction of the boxes by means of vacuum has significant advantages in terms of ergonomics and format adaptation. The good ergonomics and ease of use are the main advantages of using the inventive solution. The standstill time of the format conversion machine is shortened and possible sources of error are reduced to a minimum. It is also essential that no special knowledge of the operator for the format change is necessary.

Es steht ein hochflexibles und universell einsetzbares Transportsystem zur Verfügung, das es ermöglicht, verschiedene Produkte auf ein und derselben Maschine zu verpacken, ohne dass beim Wechsel des Formates viel Aufwand entsteht. Insbesondere werden alle Formatbereiche abgedeckt, es sind keine Formatteile notwendig, und die Schachtelträger weisen ein nur geringes Gewicht auf. Zudem ergibt sich eine praktisch automatische Formatumstellung, ein Aufrichten der Schachtel im Becher ist möglich, und es tritt praktisch keine Stauchung oder Deformation der Schachtel auf.A highly flexible and universally applicable transport system is available, which makes it possible to package different products on one and the same machine without much effort when changing the format. In particular, all format areas are covered, no format parts are necessary, and the box carrier have a low weight. In addition, there is a virtually automatic format change, an erection of the box in the cup is possible, and there is virtually no compression or deformation of the box.

Durch das Ausbleiben von Stauchungen und Deformationen können die Schachteln bereits im Schachtelhalter verschlossen werden, zusätzliche Bearbeitungsschritte wie Beschriften und Codieren der Schachtel sind durch die hohe allseitige Zugänglichkeit ebenfalls gut möglich.Due to the absence of compressions and deformations, the boxes can already be closed in the box holder, additional processing steps such as labeling and coding of the box are also well possible due to the high accessibility on all sides.

Die Schachtelträger können einen Positionsanschlag aufweisen. Ein einseitiger Anschlag definiert die Position der Schachteln.The box carriers may have a position stop. A one-sided stop defines the position of the boxes.

Die Anlagefläche der Schachtelträger weist bevorzugt eine Vielzahl von Saugöffnungen auf. Zweckmässig sind dabei mit einem Ventil, insbesondere einem Tastventil, ausgestattete Saugöffnungen. Durch die Verwendung von Tastventilen, welche nur bei anliegender Schachtel öffnen, können auch Zuschnitte, die nicht alle Saugöffnungen überdecken, gehalten werden, ohne dass die nicht bedeckten Saugöffnungen Luft ansaugen. Damit ist sichergestellt, dass der Unterdruck im Schachtelträger nicht durch nachströmende Luft abgebaut wird. Die Grösse und der Abstand der Saugöffnungen sind dabei so gewählt, dass bei den zu verarbeitenden Schachtelformaten keine nur teilweise abgedeckte Saugöffnungen auftreten können.The contact surface of the box carrier preferably has a multiplicity of suction openings. Expediently, there are suction openings equipped with a valve, in particular a feeler valve. By using contact valves, which only open when the box is in place, it is also possible to hold blanks that do not cover all the suction openings, without the uncovered suction openings sucking in air. This ensures that the negative pressure in the box carrier is not dissipated by inflowing air. The size and the spacing of the suction openings are chosen so that no only partially covered suction openings can occur in the box formats to be processed.

Jeder Schachtelträger ist mit einem eigenen, mit den Saugöffnungen in Verbindung stehenden Vakuumspeicher ausgestattet.Each box carrier is equipped with its own vacuum accumulator connected to the suction openings.

Hülsen, d.h. Schachteln mit im Verhältnis zur Bodenfläche hohen Seitenwänden werden an einer Seitenwand gehalten, die Anschlagfläche mit den Saugöffnungen steht somit senkrecht zur Umlaufebene des Transportmittels.Pods, i. Boxes with in relation to the bottom surface high side walls are held on a side wall, the stop surface with the suction openings is thus perpendicular to the orbital plane of the means of transport.

Flachzuschnitte mit einer im Verhältnis zur Bodenfläche geringen Seitenwandhöhe werden bei liegendem Schachtelträger von der horizontal ausgerichteten Anlagefläche getragen und demzufolge von unten gehalten. Der Schachtelträger ist zweckmässigerweise so ausgestaltet, dass eine Umstellung von Hülsen auf Flachzuschnitte durch eine einfache Drehung des Schachtelträgers um 90° vorgenommen werden kann.Flat blanks with a low side wall height in relation to the bottom surface are supported by the horizontally oriented contact surface when the box carrier is lying, and are therefore held from below. The box carrier is expediently designed so that a change from sleeves to flat blanks can be made by a simple rotation of the carton carrier by 90 °.

Schachtelträger mit eigenem Vakuumspeicher sind zum Entlüften und Belüften des Vakuumspeichers an einer Entlüftungs- und Belüftungsstation bevorzugt mit einem Tast-Rückschlag-Ventil ausgestattet. Dadurch kann auf eine mit grossem Aufwand einhergehende Zuführung des erforderlichen Vakuums bzw. Unterdruckes auf die umlaufenden Schachtelträger verzichtet werden. Die mit Vakuumspeichem versehenen Schachtelträger werden nur an hierfür vorgesehenen Stellen des Rundlaufes mit Vakuum beaufschlagt. Anschliessend wird der Schachtelträger abgekoppelt und hält mit Hilfe seines Vakuumspeichers den Unterdruck selbstständig.Box carriers with their own vacuum reservoir are preferably equipped with a tactile check valve for venting and venting the vacuum accumulator at a venting and aeration station. This can be dispensed with a great effort feeding the required vacuum or vacuum on the circulating box carrier. The provided with Vakuumspeichem box carrier are provided only for this purpose Setting the concentricity with vacuum. The box carrier is then uncoupled and automatically holds the vacuum using its vacuum reservoir.

Beschreibung von AusführungsbeispielenDescription of exemplary embodiments

Ein in Fig. 1 nur teilweise wiedergegebenes Rundlaufsystem 10 einer in der Zeichnung nicht näher dargestellten Verpackungsmaschine weist eine Vielzahl von an einer in einer horizontalen Ebene endlos umlaufenden Transportkette 12 angeordneten Schachtelträgern 14 mit einer eine Vorderseite bildenden Anlagefläche 16 mit zwei Saugöffnungen 18 und einem Positionsanschlag 20 für eine Faltschachtel auf. An der Rückseite der Schachtelträger 14 ist ein Vakuumspeicher 22 mit einem integrierten Tast-Rückschlagventil 24 angeordnet.An in Fig. 1 only partially reproduced concentricity system 10 of a packaging machine not shown in the drawing has a plurality of arranged on a continuously rotating in a horizontal plane conveyor chain 12 box carriers 14 with a front forming contact surface 16 with two suction ports 18 and a position stop 20 for a carton. At the back of the box carrier 14, a vacuum storage 22 is arranged with an integrated tactile check valve 24.

Das Rundlaufsystem 10 weist fünf Entlüftungsstationen 26 mit Hubsaugern zum gleichzeitigen Evakuieren des Vakuumspeichers 22 von fünf Schachtelträgern 14 auf. Zum Entlüften der Vakuumspeicher 22 docken an den Entlüftungspositionen die Hubsauger der Entlüftungsstationen 26 über eine Saugleitung 28 an der Rückseite der Schachtelträger 14 über dem Ausgang des Tast-Rückschlagventils 24 an, wobei sich ein am freien Ende der Saugleitung 28 angeordneter Saugnapf 30 an der Rückwand des Vakuumspeichers 22 festsaugt. Gleichzeitig öffnet sich aufgrund der Luftströmung das Tast-Rückschlagventil 24 und die Luft wird abgesaugt. Soll der Hubsauger sich wieder von dem Schachtelträger 14 lösen, so wird ein kurzer Abblasimpuls gegeben, der auch wieder aufgrund der Strömungsrichtungsumkehr eine Kugel im Tast-Rückschlagventil 24 auf ihren Sitz drückt. Im Schachtelträger 14 befindet sich nun ein Vakuum.The concentricity system 10 has five deaeration stations 26 with lifting suckers for simultaneously evacuating the vacuum reservoir 22 from five box carriers 14. For venting the vacuum accumulator 22 dock at the ventilation positions the lifting suction of the vent stations 26 via a suction line 28 on the back of the box carrier 14 on the output of Tast-check valve 24, with a arranged at the free end of the suction line 28 suction cup 30 at the rear wall of the Vacuum accumulator 22 sucks. At the same time opens due to the flow of air, the tactile check valve 24 and the air is sucked. If the lifting sucker to release again from the box carrier 14, so a short Abblasimpuls is given, which again presses a ball in the Tast-check valve 24 on their seat due to the flow direction reversal. The box carrier 14 is now a vacuum.

Am Maschinenauslauf sind entsprechend der Anzahl der Entlüftungsstationen 26 fünf Pneumatikzylinder 32 so angeordnet, dass diese zum gleichzeitigen Belüften von fünf Schachtelträgern 14 den Vakuumkammern 22 gegenüberstehen. Bei Betätigung der Pneumatikzylinder 32 drückt eine Zylinderstange 34 in Axialrichtung y von der Rückwandseite der Vakuumkammer 22 auf das Tast-Rückschlagventil 24 und drückt dieses in Axialrichtung y um etwa 3 mm ein. Bei diesem Vorgang löst sich ein als Dichtring eingesetzter O-Ring von der Innenwand des Vakuumspeichers 22, so dass Luft von aussen in die Vakuumkammer 22 einströmt. Durch dieses Belüften des Vakuumspeichers 22 werden die den Anlageflächen 16 anliegenden und durch einen Unterdruck an den Schachtelträgern 14 gehaltenen Schachteln von den Schachtelträgern 14 gelöst.At the machine outlet 26 five pneumatic cylinders 32 are arranged according to the number of ventilation stations so that they face the vacuum chambers 22 for simultaneous venting of five box carriers 14. Upon actuation of the pneumatic cylinder 32 pushes a cylinder rod 34 in Axial direction y from the rear wall side of the vacuum chamber 22 to the tactile check valve 24 and presses this in the axial direction y by about 3 mm. In this process, an O-ring inserted as a sealing ring separates from the inner wall of the vacuum accumulator 22, so that air flows from the outside into the vacuum chamber 22. As a result of this venting of the vacuum accumulator 22, the cartons lying against the abutment surfaces 16 and held by a vacuum on the carton carriers 14 are released from the carton carriers 14.

Ein in den Fig. 2 und 3 gezeigter Schachtelträger 14 für Hülsen weist zwei Saugöffnungen 18 auf. In jeder Saugöffnung 18 ist ein Tastventil 36 mit einem von der vertikal stehenden Ebene der Anlagefläche 16 aufragenden Taststift 38 angeordnet. Beim Anlegen einer Hülse oder Faltschachtel an die Anlagefläche 16 und an den von der Anlagefläche 16 rechtwinklig abragenden Positionsanschlag 20 werden nur diejenigen Taststifte 38 eingedrückt und dadurch die Tastventile 36 geöffnet, die von der anliegenden Faltschachtel überdeckt sind. Bei einer grossen Anzahl unterschiedlicher Formate kann es sich als zweckmässig erweisen, eine grössere Anzahl Saugöffnungen 18 über die Anlagefläche 16 regelmässig anzuordnen.One in the FIGS. 2 and 3 shown box carrier 14 for sleeves has two suction openings 18. In each suction opening 18, a Tastventil 36 is arranged with a projecting from the vertical plane of the contact surface 16 stylus 38. When creating a sleeve or carton to the contact surface 16 and at the right angles from the contact surface 16 projecting position stop 20 only those styli 38 are pressed and thereby the tactile valves 36 are opened, which are covered by the adjacent carton. With a large number of different formats, it may prove expedient to arrange a larger number of suction openings 18 on the contact surface 16 regularly.

Die Explosionsdarstellung von Fig. 4 zeigt den Aufbau des in den Fig. 2 und 3 dargestellten Schachtelträgers 14 mit zwei Saugöffnungen 18 mit je einem Tastventil 36 mit Taststift 38 in einer mit einer Schachtelträger-Grundplatte 42 verschraubten Schachtelträger-Blende 40. Der als Platte ausgebildete Positionsanschlag 20 ist seitlich an der Schachtelträger-Grundplatte 42 angeschraubt. Ein schachtelförmiges Rückwandteil 44 ist über eine Flachdichtung 46 mit der Grundplatte 42 verschraubt und bildet den Vakuumspeicher 22. Innerhalb des Vakuumspeichers 22 ist das Tast-Rückschlagventil 24 an einem seiner Enden in einem Ventilhalter 48 in Axialrichtung y verschiebbar gelagert und drückt mit einer O-Ringdichtung 50 an seinem anderen Ende gegen die Innenwand des mit einer Öffnung 52 versehenen Rückwandteils 44. Zur Befestigung des Schachtelträgers 14 an der umlaufenden Transportkette 12 ragt eine mit der Transportkette 12 verschraubbare Halterung 54 von der Grundplatte 42 nach unten ab.The exploded view of Fig. 4 shows the structure of the in the FIGS. 2 and 3 illustrated box carrier 14 with two suction ports 18, each with a feeler valve 36 with stylus 38 in a screwed to a box base plate 42 box carrier panel 40. Formed as a plate position stop 20 is laterally bolted to the box base plate 42. A box-shaped rear wall part 44 is screwed to the base plate 42 via a flat seal 46 and forms the vacuum reservoir 22. Within the vacuum accumulator 22, the tactile check valve 24 is displaceably mounted at one of its ends in a valve holder 48 in the axial direction y and presses with an O-ring seal 50 at its other end against the inner wall of the provided with an opening 52 rear wall portion 44. For attachment of the box carrier 14 to the rotating conveyor chain 12 protrudes a screwed with the transport chain 12 bracket 54 from the base plate 42 down from.

Das Tast-Rückschlagventil 24 ist gemäss Fig. 5 in einer die O-Ringdichtung 50 tragenden Ventilaufnahme 56 gehalten und zur gleitenden Lagerung in Axialrichtung y in den Ventilhalter 48 eingesetzt. Zwischen der Ventilaufnahme 56 und einer zur Anlage am Ventilhalter 48 vorgesehenen Federstahlscheibe 58 ist eine Druckfeder 60 angeordnet.The Tast-check valve 24 is according Fig. 5 held in a valve seat 56 carrying the O-ring seal 50 and used for sliding storage in the axial direction y in the valve holder 48.

Fig. 6 zeigt einen Schachtelträger 14 mit horizontal stehender Anlagefläche 16 mit vier Saugöffnungen 18. Fig. 6 shows a box carrier 14 with horizontally stationary contact surface 16 with four suction openings 18th

Die in den Fig. 7 bis 9 gezeigten Einrichtungen dienen dem Schliessen des Bodens der von einem in der Zeichnung nicht dargestellten Toploader an die Schachtelträger 14 übergebenen Faltschachteln oder Hülsen 62 vor deren Befüllen. Die auf der Transportkette 12 montierten Schachtelträger 14 mit den Faltschachteln 62 werden zum Schliessen des Schachtelbodens nacheinander an einer Vorknickstation 64 und an einer Schliessstation 70 vorbeigeführt.The in the Fig. 7 to 9 shown devices serve the closing of the bottom of the toploader not shown in the drawing to the carton carrier 14 handed over cartons or sleeves 62 before filling. The box carriers 14 with the folding boxes 62 mounted on the transport chain 12 are guided one after the other at a precutting station 64 and at a closing station 70 for closing the box bottom.

In der Vorknickstation 64 steht der Boden an einer Leiste 66 an und ein Knickhebel 68 knickt die Stecklasche. Anschliessend bringt der Kettentransport den Schachtelträger 14 in die Schliessstation 70. Hier fährt zunächst ein Staublaschenknicker 72 aus und knickt Laschen ein. Sodann schliesst ein Schwenkrechen 74 den Boden von hinten. Gleichzeitig fährt der Staublaschenknicker 72 wieder ein, und der Boden wird durch ein Führungsblech mit dem Schwenkrechen 74 komplett geschlossen. Anschliessend fährt der Schwenkrechen 74 wieder zurück.In the Vorknickstation 64, the floor is on a bar 66 and a buckling 68 kinks the tab. Subsequently, the chain transport brings the box carrier 14 into the closing station 70. Here, first a dust flap breaker 72 extends and folds tabs. Then, a pivoting rake 74 closes the floor from behind. At the same time, the dust flap breaker 72 retracts, and the bottom is completely closed by a guide plate with the pivoting rake 74. Subsequently, the pivoting rake 74 moves back again.

Mit den vorstehend dargelegten Ausführungsbeispielen werden die folgenden Anforderungen erfüllt:

  • Das System ist geeignet für Schachteln aus Hülse und/oder Flachzuschnitt.
  • Reproduzierbarer und schneller Formatwechsel (±0,5mm) mit möglichst wenig Verstellmöglichkeit durch die Bedienperson.
  • Hohe Flexibilität bezüglich Layout (Material Zu- und Abfluss).
  • Hohe Schachtelleistung (bis 300 Stück/min).
With the embodiments set forth above, the following requirements are met:
  • The system is suitable for boxes made of sleeve and / or flat blank.
  • Reproducible and fast format change (± 0.5mm) with as little adjustment as possible by the operator.
  • High flexibility regarding layout (material inflow and outflow).
  • High box performance (up to 300 pieces / min).
