Description

Die vorliegende Erfindung betrifft eine Vorrichtung an einer Verpackungsmaschine zur Bildung von Gruppen hochkant stehender, scheibenförmiger Gegenstände, insbesondere Biskuits gemäss dem Oberbegriff des unabhängigen Patentanspruchs 1 sowie ein Verfahren zu ihrem Betrieb gemäss dem Oberbegriff des Patentanspruches 4 (bekannt aus der GB-A-2 065 055).The present invention relates to a device on a packaging machine for forming groups of upright, disc-shaped objects, in particular biscuits according to the preamble of independent claim 1 and a method for their operation according to the preamble of claim 4 (known from GB-A-2 065 055).

Die Gruppierung von Gegenständen, insbesondere Biskuits bildete schon seit langem ein Problemkreis, weil einerseits eine schonende Behandlung zur Vermeidung von Beschädigungen und anderseits eine genaue Abzählung zur Bildung von Gruppen mit gleicher Anzahl Biskuits oder mit gleichem Gewicht pro Gruppe verlangt wird. Dazu soll die Leistung der Verpackungsmaschine möglichst hoch sein.The grouping of objects, especially biscuits, has long been a problem because, on the one hand, careful handling to avoid damage and, on the other hand, precise counting is required to form groups with the same number of biscuits or with the same weight per group. For this purpose, the performance of the packaging machine should be as high as possible.

In der GB-PS-2 116 508 ist eine bekannte Ausführungsform einer Vorrichtung zur Bildung mehrerer nebeneinanderliegenden Gruppen beschrieben. Die Biskuits werden aus dem Backofen in beispielsweise zwölf Reihen ausgerichtet und in einem Fallschacht hochkant gestellt und dann in zwei Gruppen mit Stössern einer Transportkette zugeschoben, damit werden Gruppen von sechs Gegenständen gebildet. Diese können dann einem weiteren Förderorgan zugeschoben werden, das mit Mitnehmern versehen ist, die Gruppen hintereinander weitertransportieren.GB-PS-2 116 508 describes a known embodiment of a device for forming a plurality of adjacent groups. The biscuits are aligned out of the oven in, for example, twelve rows and placed upright in a chute and then pushed in two groups with pushers along a transport chain, so that groups of six objects are formed. These can then be pushed to a further funding body, which is provided with carriers that transport groups in succession.

Diese Ausbildung kann herstellerseitig für eine beliebige Anzahl von Gegenständen pro Gruppe gebaut werden. Später kann diese Zahl nicht mehr geändert werden. Der Transport erfolgt schrittweise mit positiven und negativen Beschleunigungsphasen, was zerbrechlichem Gut schaden kann. Die vom Ofen kommenden Reihen von Gegenständen müssen genau abgezählt sein, wenn ein Gegenstand fehlt, kann dies nicht mehr ausgeglichen werden.This training can be built by the manufacturer for any number of objects per group. This number cannot be changed later. The transport takes place gradually with positive and negative acceleration phases, which can damage fragile goods. The rows of items coming from the oven must be counted exactly; if an item is missing, this can no longer be compensated for.

Eine andere Art einer Vorrichtung zum Abzählen von Gegenständen zwecks Bildung von Gruppen ist in der GB-A-2 065 055 beschrieben. Die Gruppenbildung erfolgt mit einem Förderrad, das eine Anzahl radialer und begrenzt schwenkbar gehalterter Mitnehmer aufweist. Die liegend angelieferten Gegenstände werden damit einzeln um 90° gedreht, so dass sie hochkant stehen. In einem Antrittsbereich werden die Gegenstände auf eine Schiene geschoben, wo sie gruppenweise von einem Förderfinger übernommen und einem weiteren Fördermittel zugeführt werden. Diese Vorrichtung gewährleistet gleichförmige Transportgeschwindigkeiten für jede Phase. Die Gegenstände werden höchstens geringen Reibungen unterworfen und praktisch kaum auf Druck beansprucht. Die Gruppenlänge kann einfach umgestellt werden.Another type of device for counting objects to form groups is described in GB-A-2 065 055. The grouping is carried out with a conveyor wheel which has a number of radial and limitedly pivotable carriers. The items delivered horizontally are thus rotated individually by 90 ° so that they stand upright. In an entry area, the objects are pushed onto a rail, where they are taken over in groups by a conveyor finger and fed to another funding. This device ensures uniform transport speeds for each phase. The objects are subjected to little or no friction and are hardly subjected to pressure. The group length can be easily changed.

Nachteilig ist jedoch, dass immer nur eine Gruppe pro Zyklus gebildet werden kann. Dadurch wird die Leistung der Verpackungsmaschine stark eingeschränkt.However, it is disadvantageous that only one group can be formed per cycle. This severely limits the performance of the packaging machine.

Es ist deshalb eine Aufgabe der Erfindung, diese letztgenannte Vorrichtung in der Weise zu verbessern, dass jeweils mehrere Gruppen gleichzeitig weitergegeben werden können, um so die Geschwindigkeiten zu vergrössern.It is therefore an object of the invention to improve this latter device in such a way that several groups can be passed on at the same time in order to increase the speeds.

Erfindungsgemäss wird dies mit einer Vorrichtung mit den Merkmalen im kennzeichnenden Teil des unabhängigen Patentanspruchs 1 erreicht. Das Verfahren zu ihrem Betrieb ist im Patentanspruch 4 gekennzeichnet.According to the invention, this is achieved with a device having the features in the characterizing part of independent patent claim 1. The method for their operation is characterized in claim 4.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Es zeigen:

  • Fig. 1 einen Querschnitt durch die erfindungsgemässe Vorrichtung nach der Schnittlinie I - in Fig. 2,
  • Fig. 2 eine Ansicht der Vorrichtung von der Linie II - 11 von Fig. 1 aus betrachtet, und
  • Fig. 3 - 5 jeweils dieselbe Partie des Querschnittes in Fig. 1 zu drei verschiedenen Zeiten beim Betrieb der Vorrichtung.
An embodiment of the invention is explained below with reference to the drawing. Show it:
  • 1 shows a cross section through the device according to the invention along the section line I - in FIG. 2,
  • Fig. 2 is a view of the device viewed from line II - 11 of Fig. 1, and
  • FIGS. 3-5 each have the same part of the cross section in FIG. 1 at three different times in the operation of the device.

Die in Fig. 1 und 2 dargestellte Vorrichtung schliesst an eine nicht gezeichnete Herstellermaschine an, mit der sandwichförmige Biskuits aus zwei Gebäckscheiben mit dazwischen eingebrachter Füllung, z. B. Schokolade oder -creme, hergestellt werden. Es ist offensichtlich, dass damit Gegenstände mit variabler Dicke gebildet werden, die zudem äusserst stossempfindlich sein können.The device shown in FIGS. 1 and 2 connects to a manufacturing machine, not shown, with which sandwich-shaped biscuits made from two pastry slices with a filling placed in between, e.g. B. chocolate or cream. It is obvious that this creates objects of variable thickness, which can also be extremely sensitive to impact.

Die Biskuits 1 werden dabei mit äquidistant an einem Fördermittel 4, beispielsweise einer Kette oder einem Band drehbar befestigten Mitnehmern 3 auf einem Gleittisch 2 transportiert. Am Ende dieses Gleittisches 2 schliesst als zweites Förderorgan ein Förderrad 5 an, das gemäss dem Pfeil A um eine angetriebene Achse 6 rotiert wird. Das Förderrad 5 besitzt zwei drehfest mit der Achse 6 verbundene Scheiben 7, in denen eine Vielzahl von Achsen 8 begrenzt schwenkbar gelagert sind. Jede Achse 8 trägt eine der Anzahl der nebeneinander liegenden Förderbahnen 4 entsprechende Anzahl Mitnehmer 9, die beim Umlauf des Förderrades 5 mit dem Gleittisch 2 kämmen und jeweils ein Biskuit 1 aufnehmen. Seitlich werden die Biskuits auf dem Weg des Förderrades 5 mittels Führungsstäben geführt, die beim Eintrittsbereich koaxial zur Achse 6 gebogen sind und im Austrittsbereich, der einen Sammelkanal 11 bildet, tangential vom Förderrad 5 abstehen, so dass die Mitnehmer im letztgenannten Bereich aus der Führungsbahn mit den Führungsstäben 10 austreten können.The biscuits 1 are transported on a sliding table 2 with carriers 3 rotatably attached equidistantly to a conveying means 4, for example a chain or a belt. At the end of this sliding table 2, a conveyor wheel 5 connects as a second conveying member, which is rotated about a driven axis 6 according to arrow A. The feed wheel 5 has two disks 7 connected to the axle 6 in a manner fixed against relative rotation, in which a plurality of axles 8 are pivotally supported to a limited extent. Each axis 8 carries a number of drivers 9 corresponding to the number of conveyor tracks 4 lying next to one another, which mesh with the sliding table 2 when the conveyor wheel 5 rotates and each take up a biscuit 1. The biscuits are guided laterally on the path of the conveyor wheel 5 by means of guide rods, which are bent coaxially to the axis 6 at the entry area and protrude tangentially from the delivery wheel 5 in the exit area, which forms a collecting channel 11, so that the drivers in the latter area also leave the guide track the guide rods 10 can exit.

An dieser Stelle befindet sich nun ein erstes Greifermittel, das aus zwei seitlich des Sammelkanals 11 angeordneten, mit in den Weg der Biskuits eingreifenden Greiferelementen 14a, 15a ausgerüsteten Gabeln 14, 15 gebildet ist und auf einer Schiene 32 gleitend und mit nicht dargestellten seitlichen Führungselementen eine Bewegung gemäss der strichliert in Fig. 1 und 3 eingezeichneten Bahn 20 auszuführen imstande ist. Solche Greifermittel und deren Antriebselemente sind in der Verpackungsmaschinentechnik bekannt und brauchen deshalb an dieser Stelle nicht weiter beschrieben zu werden.At this point there is now a first gripper means which is formed from two forks 14, 15 arranged laterally of the collecting channel 11 and equipped with grippers 14a, 15a which engage in the path of the biscuits and sliding on a rail 32 and with lateral guide elements, not shown, is capable of executing a movement according to the path 20 shown in dashed lines in FIGS. 1 and 3. Such gripper means and their drive elements are known in packaging machine technology and therefore do not need to be described further here.

Ein zweites Greifermittel mit Trennfingern 16, 17 an einem Hebelarm 31 befindet sich über dem Sammelkanal 11. Der Hebelarm 31 ist, aus der Antriebstechnik bekannter Weise, beispielsweise durch Kurvenscheibe und Kurvenabtaster in der Weise gesteuert, dass die freien Enden der Trennfinger 16, 17 eine Bahn gemäss dem strichpunktiert gezeichneten Weg 19 auszuführen imstande ist. Damit werden gemäss diesem Ausführungsbeispiel zwei gebildete Gruppen 12, 13 gleichzeitig der Übergabestelle 18, die geradlinig an den Sammelkanal 11 anschliesst, geschoben.A second gripper means with separating fingers 16, 17 on a lever arm 31 is located above the collecting duct 11. The lever arm 31 is controlled in a manner known from drive technology, for example by means of a cam disk and cam scanner, in such a way that the free ends of the separating fingers 16, 17 are one Is able to execute the path according to path 19 drawn in dash-dotted lines. Thus, according to this embodiment, two groups 12, 13 formed are simultaneously pushed to the transfer point 18, which connects to the collecting duct 11 in a straight line.

An der Übergabestelle 18 befindet sich ein schwenkbar gelagerter Tisch 33, der von drei Führungsschienen 22, 23, 24 durchdrungen ist und ebenfalls in gleicher Weise wie die in der Verpackungstechnik bekannten Ablegeschaufeln verschwenkt wird, um die darauf befindlichen Gruppen von Gegenständen 12, 13 auf ein drittes Förderorgan 25 abzulegen.At the transfer point 18 there is a pivotally mounted table 33, which is penetrated by three guide rails 22, 23, 24 and is also pivoted in the same way as the depositing vanes known in packaging technology, around the groups of objects 12, 13 located thereon to put third funding body 25.

Durch besondere Wahl der Geschwindigkeiten, insbesondere dadurch, dass das Eingreifen und Weiterschieben der gerade gebildeten Gruppen 12,13 auf dem Sammelkanal 11 synchron mit der Bewegung des Förderrades 5 verläuft, wird eine schonende Behandlung der Biskuits bei der Gruppenbildung gewährleistet.A special choice of the speeds, in particular in that the engagement and pushing of the groups 12, 13 just formed on the collecting channel 11 runs synchronously with the movement of the feed wheel 5, ensures gentle handling of the biscuits when forming the groups.

Wenn dann die translatorische Verschiebung des Trennfingerpaares 16, 17 in Richtung gegen die Übergabestelle 18 mit einer grösseren Geschwindigkeit als die translatorische Geschwindigkeit des ersten Greifermittels 14, 15 geschieht, kann jeweils eine Lücke gebildet werden, die bei höherem Materialeinfluss eine Rückkehr der zweiten Greifermittel 16, 17 erlauben. Dabei ist aber darauf zu achten, dass das Absenken der Trennfinger 16, 17 gegen den Sammelkanal 11 ebenfalls synchron zur Bewegung vom ersten Greifermittel 14, 15 und damit zum Transportrad 5 erfolgt.If the translatory displacement of the pair of separating fingers 16, 17 in the direction towards the transfer point 18 then occurs at a greater speed than the translatory speed of the first gripper means 14, 15, a gap can be formed in each case, which means that the second gripper means 16, Allow 17. It should be ensured, however, that the lowering of the separating fingers 16, 17 against the collecting channel 11 also takes place synchronously with the movement of the first gripper means 14, 15 and thus towards the transport wheel 5.

In der Phase gemäss Fig. 3 sind zwei Gruppen 12,13 durch das Trennfingerpaar 16, 17 von der Sammelschiene 11 zur Übergabestation 18 verschoben worden, da dies mit einer grösseren Geschwindigkeit erfolgte als der Transport mit dem Transportrad 5, liegt die Sammelschiene 11 praktisch leer da, denn es wurden bisher nur zwei Biskuits einer weiteren Gruppe 12A auf dieselbe geschoben. Die Gabeln 14, 15 werden auf der Bahn 20 in Richtung des Pfeiles 26 (Fig. 3) nach rückwärts bewegt.In the phase according to FIG. 3, two groups 12, 13 have been moved by the separating finger pair 16, 17 from the busbar 11 to the transfer station 18, since this took place at a higher speed than the transport by the transport wheel 5, the busbar 11 is practically empty there, because so far only two biscuits from another group 12A have been pushed onto the same. The forks 14, 15 are moved backwards on the track 20 in the direction of the arrow 26 (FIG. 3).

Der Tisch 33 in der Übergabestelle 18 wird anschliessend abgesenkt, wie Fig. 4 zeigt.The table 33 in the transfer point 18 is then lowered, as shown in FIG. 4.

Dabei übernehmen die Schienen 22, 23, 24 die Funktion der Trennfinger 16, 17, um die beiden Gruppen 12, 13 bei ihrer Übergabe an das dritte Förderorgan 25 voneinander getrennt zu halten. In dieser Zeit wurde auch die neue Gruppe 12A gebildet und kann nun mit den Gabeln 14, 15 durch Verschieben der Antriebsstange 32 nach vorn auf die Sammelschiene 11 geschoben werden. Gleichzeitig werden die Trennfinger 16, 17 auf der Bahn 28 zurückbewegt.The rails 22, 23, 24 take over the function of the separating fingers 16, 17 in order to keep the two groups 12, 13 separate from one another when they are transferred to the third conveying member 25. During this time the new group 12A was also formed and can now be pushed forwards onto the busbar 11 with the forks 14, 15 by moving the drive rod 32 forward. At the same time, the separating fingers 16, 17 are moved back on the web 28.

Während sich gemäss Fig. 5 die neue zweite Gruppe 13A bildet, gelangt die vorangehende neue erste Gruppe 12A an ihre vorderste Stelle vor der Übergabe an die Übergabestation 18. Die Trennfinger 16, 17 bewegen sich nun gemäss dem Bahnabschnitt 29 hinter die zweite Gruppe 13A bzw. zwischen die beiden Gruppen 12A, 13A.5, the new second group 13A forms, the preceding new first group 12A reaches its foremost position before transfer to the transfer station 18. The separating fingers 16, 17 now move behind the second group 13A or between the two groups 12A, 13A.

Während der Rückwärtsbewegung der Trennfinger 16, 17, hatte auch der Tisch 33 Zeit, in die Übergabestelle 18 zurückzukehren. Damit kommt als nächstes wieder ein Bewegungsablauf bis die Lage gemäss Fig. 3 erreicht wurde.During the backward movement of the separating fingers 16, 17, the table 33 also had time to return to the transfer point 18. The next step is a sequence of movements until the position according to FIG. 3 has been reached.

Für die synchrone Steuerung der Bewegungen von Gabeln, Trennfingern und Tisch können bekannte Kurvenscheiben mit Kurvenabtastern verwendet werden, die von demselben Antrieb aus angetrieben werden, wie das Förderrad 5.Known cams with cam scanners can be used for the synchronous control of the movements of forks, separating fingers and table, which are driven by the same drive as the feed wheel 5.
