The underside of the rail serves as contact surface during compression of the adhesive point, and the taped box is then pushed off the rail. A tape is placed on a box, folded downwards on both box sides in a first step, in a second step, one tape half is folded under the support surface and the second adhesive-coated half is placed over the first half. The taping appliance consists of transporter with flat ribbed rail, tape dispenser, adhesive station, folding station, and compression station.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Banderolieren von Eierschachteln, bei dem die Eierschachteln auf einer Schiene schrittweise vorgeschoben werden, die Banderole über die Schachteln gelegt, um diese herum angedrückt, gefaltet und die Enden verklebt werden. Die Erfindung betrifft ferner eine Maschine zum Banderolieren von Eierschachteln, die nach dem erfindungsgemässen Verfahren arbeitet.The present invention relates to a method for banding egg cartons in which the egg boxes are progressively advanced on a rail, the band placed over the boxes, pressed around them, folded and the ends glued. The invention further relates to a machine for banding egg boxes, which operates according to the inventive method.

Heute werden Eier verschiedenster Qualität auf dem Markt angeboten, bei denen nicht nur das Legedatum interessiert, sondern auch Informationen betreffend der Hühnerhaltung interessieren. Um diese Informationen auch kontrollieren zu können, müssen beispielsweise auch Name und Anschrift des Produzenten auf den Eierschachteln angegeben sein. Am einfachsten erfolgt dies durch Aufkleben eines Etikettes auf der planen Oberfläche der Eierschachtel. Diese Methode ist zwar preiswert, berücksichtigt jedoch nicht, dass Eierschachteln oftmals mehrfach benutzt werden. Ein mehrfaches Ueberkleben ist jedoch nicht erwünscht.Today, eggs of various quality are offered on the market, where not only the laying date is of interest, but also information about keeping chicken. In order to be able to control this information, for example, the name and address of the producer must also be indicated on the egg boxes. The easiest way to do this is by sticking a label on the flat surface of the egg box. Although this method is inexpensive, it does not take into account that egg cartons often used several times. A multiple gluing is not desirable.

Entsprechend sind heute auch Eierschachteln auf dem Markt, die mit einer Banderole umschlagen sind. Für kleinere Eierproduzenten werden entsprechend fertige Banderolen angeboten, die mit einer anfeuchtbaren Kleblasche versehen sind oder auf die entsprechender Klebstoff aufgetragen werden kann. Dies hat jedoch verschiedene Nachteile. Zum einen sitzen solche Banderolen nicht sehr straff und lassen sich entsprechend von der Schachtel abschieben. Dies hat damit zu tun, dass die Klebeseite auf der Unterseite der Eierschachtel zu liegen kommen muss, wobei jedoch die Eierschachtelunterseite völlig uneben ist. Entsprechend erfolgt die Klebung während die Klebstelle auf der Oberfläche der Schachtel liegt, worauf anschliessend die Banderole so verschoben wird, dass die Klebstelle nach unten zu liegen kommt. Diese Methode ist zwar äusserst preiswert, führt jedoch zu einem völlig unbefriedigenden Resultat.Accordingly, egg boxes are on the market today, which are handled with a band. For smaller egg producers correspondingly finished bands are offered, which are provided with a moistenable adhesive bag or can be applied to the appropriate adhesive. However, this has several disadvantages. On the one hand, such banderoles are not very tight and can be removed from the box accordingly. This has to do with the fact that the adhesive side must come to rest on the bottom of the egg box, but the bottom of the egg box is completely uneven. Accordingly, the gluing is done while the adhesive is on the surface of the box, whereupon the band is shifted so that the gluing point comes to lie down. Although this method is extremely inexpensive, it leads to a completely unsatisfactory result.

Bei der Verwendung von Eierschachteln aus Kunststoff werden auch Banderolen aus Halbkarton verwendet, die mit einer bestimmten Formgebung versehen sind, entsprechende Aufreissperforierungen aufweisen und sowohl manuell als auch maschinell um die entsprechenden Eierschachteln angelegt werden können. Dank der Verwendung von Halbkarton spielt die unebene Unterseite der Eierschachtel keine Rolle. Die Kosten solcher Banderolen aus Halbkarton sind relativ hoch und lohnen sich nur, um in entsprechend grossen Quantitäten hergestellt zu werden. Auch ist es nicht möglich, bei solchen Banderolen von einer Endlosvorratsrolle zu arbeiten. Für die meisten kleinen bis mittleren Eier produzierenden Betriebe kommen solche Banderolen aus Halbkarton daher nicht in Frage.When using plastic egg cartons also half board strips are used, which are provided with a specific shape, have corresponding tear perforations and can be created both manually and mechanically around the corresponding egg boxes. Thanks to the use of half board, the uneven underside of the egg box does not matter. The costs such banderoles of cardboard are relatively high and worthwhile only to be produced in correspondingly large quantities. Also, it is not possible to work with such banderoles of an endless supply roll. For most small to medium-sized eggs producing companies such banderoles of cardboard are therefore out of the question.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Verfahren der eingangs genannten Art zu schaffen, bei dem die genannten Probleme gemieden werden können.It is therefore the object of the present invention to provide a method of the type mentioned, in which the problems mentioned can be avoided.

Es ist eine weitere Aufgabe der vorliegenden Erfindung, eine Maschine anzubieten, mit der Eierschachteln mit einer Papierbanderole versehen werden können, wobei die Klebstelle direkt im Bereich der Eierschachtelunterseite angebracht werden kann.It is a further object of the present invention to provide a machine with which egg boxes can be provided with a paper band, wherein the adhesive point can be applied directly in the area of the egg box base.

Ein Verfahren, welches die Aufgabe der Erfindung erfüllt, geht aus dem Anspruch 1 hervor. Das wesentliche Prinzip der Erfindung liegt darin, dass die Banderole nicht nur die Eierschachtel umgibt, sondern während des Banderolierens um die als Auflagefläche für die Eierschachteln dienende Schiene erfolgt. Die Schiene bildet so eine Andruckfläche, auf der die Klebestelle verpresst werden kann. Weitere vorteilhafte Verfahrensschritte gehen aus den entsprechenden abhängigen Ansprüchen hervor und sind in der nachfolgenden Beschreibung mit Bezug auf die Zeichnungen erläutert.A method which fulfills the object of the invention is evident from claim 1. The essential principle of the invention is that the band not only surrounds the egg box, but is done during banding around serving as a support surface for the egg boxes rail. The rail thus forms a contact surface on which the splice can be pressed. Further advantageous method steps emerge from the corresponding dependent claims and are explained in the following description with reference to the drawings.

Eine Maschine, mittels der ein Banderolierverfahren der erfindungsgemässen Art durchgeführt werden kann, geht aus Anspruch 6 hervor und weitere vorteilhafte Ausgestaltungsformen dieser Maschine gehen aus den abhängigen auf den Anspruch 6 direkt oder indirekt zurückbezogenen Ansprüchen hervor. In der Beschreibung ist auch die Bedeutung dieser abhängigen Ansprüche erläutert.A machine, by means of which a banding method of the inventive type can be performed, is apparent from claim 6 and further advantageous embodiments of this machine will become apparent from the dependent claim 6 directly or indirectly back related claims. The description also explains the meaning of these dependent claims.

FIG. 10
the same device in a vertical section perpendicular to the feed direction of the egg boxes cut in the folding station.

Die erfindungsgemässe Maschine zum Banderolieren von Eierschachteln ist aufgebaut auf einer horizontalen Chassisplatte 1 und einer damit verbundenen vertikalen Chassisplatte 2. Eine Arbeitsplatte 3, welche die Ebene darstellt, in der die Eierschachteln E bewegt werden, ist zur besseren Sichtbarkeit der verschiedenen Maschinenelemente nur andeutungsweise dargestellt, ansonsten jedoch weggelassen. Praktisch mit der Ebene der Arbeitsplatte 3 fluchtend ist eine Flachschiene 4 gezeigt, auf der die zu banderolierenden Eierschachteln von links nach rechts bewegt werden. Eine insgesamt mit der Bezugszahl 6 bezeichnete Transportvorrichtung bewegt die Eierschachteln E schrittweise von der Einführseite in Abstossrichtung durch die Maschine hindurch. Die Transportvorrichtung 6 besteht aus einem Flachstab 7, der aus einem Flachblech geformt ist und dessen beide Enden als endseitige Schieber 8 um 90° nach unten abgewinkelt sind. Ferner ist am Flachstab 7 noch ein mittiger Schieber 9 ebenfalls vertikal nach unten gerichtet befestigt. Zwischen dem mittigen Schieber 9 und den in Abstossrichtung vorderen, endseitigen Schieber 8 sind unten zwei Federplatten 10 als Niederhalter angeordnet. Mittels einer über dem Flachstab 7 liegenden Kolbenzylindereinheit 11, die ebenfalls zur Transportvorrichtung 6 gehört, lässt sich der Flachstab 7 um die Hälfte seiner Länge vor- und zurückschieben. Hierzu ist die Kolbenstange 12 der Kolbenzylindereinheit 11 an einem Mitnehmer 13 befestigt. Die gesamte Transportvorrichtung 6 ist auf einer abgewinkelten Hebeplatte 14 gelagert. Der Flachstab 7 läuft auf teleskopischen Schienen 15, die auf der Unterseite des horizontalen Schenkels der abgewinkelten Hebeplatte 14 befestigt sind. Die Hebeplatte 14 läuft für ihre Vertikalbewegungen in Vertikalschienen 16, die mittels Distanzelementen 17 auf der Chassisplatte 2 montiert sind.The inventive machine for banding egg boxes is constructed on a horizontal chassis plate 1 and an associated vertical chassis plate 2. A worktop 3, which represents the plane in which the egg boxes E are moved, is for better visibility of the various machine elements shown only hinted, but otherwise omitted. Almost aligned with the plane of the worktop 3, a flat rail 4 is shown, on which the egg boxes to be banded are moved from left to right. A generally designated by the reference numeral 6 transport device moves the egg boxes E gradually from the insertion side in the direction of repulsion through the machine. The transport device 6 consists of a flat bar 7, which is formed from a flat sheet and whose two ends are angled as an end slide 8 by 90 ° down. Further, the flat bar 7 is still a central slide 9 also directed vertically directed downwards. Between the central slide 9 and the front, end-side slide 8 in the direction of repulsion, two spring plates 10 are arranged below as hold-down. By means of a lying above the flat bar 7 piston-cylinder unit 11, which also belongs to the transport device 6, the flat bar 7 can be pushed back and forth by half its length. For this purpose, the piston rod 12 of the piston-cylinder unit 11 is fastened to a driver 13. The entire transport device 6 is mounted on an angled lifting plate 14. The flat bar 7 runs on telescopic rails 15 which are mounted on the underside of the horizontal leg of the angled lifting plate 14. The lifting plate 14 runs for their vertical movements in vertical rails 16, which are mounted by means of spacers 17 on the chassis plate 2.

Die hier dargestellte Maschine ist so konzipiert, dass in jeder Arbeitsstufe immer gleichzeitig zwei Eierschachteln E miteinander bearbeitet werden können. In der hier dargestellten Ausführungsform ist die Transportvorrichtung 6 so ausgelegt, dass immer sechs Schachteln gleichzeitig bewegt werden. Hierdurch lässt sich eine höhere Durchstossfrequenz erreichen. Ohne eine funktionelle Einbusse zu erleiden, könnte jedoch die Transportvorrichtung auch um die Hälfte verkürzt werden, so dass maximal immer nur drei Schachteln gleichzeitig verschoben werden.The machine shown here is designed in such a way that two egg boxes E can always be processed simultaneously in each work step. In the embodiment shown here, the transport device 6 is designed so that always six boxes are moved simultaneously. This can achieve a higher penetration frequency. Without suffering a functional loss, however, the transport device could be shortened by half, so that a maximum of only three boxes are moved simultaneously.

In einem ersten Arbeitsschritt, wie er in der Figur 1 dargestellt ist, werden zwei bereitstehende Eierschachteln E mittels der Transportvorrichtung 6 auf die Flachschiene 4 geschoben. Hierbei liegen die Schachteln E auf die nicht dargestellte Arbeitsfläche 3 auf oder auf einer hier ebenfalls nicht dargestellten Verlängerung der Flachschiene 4. Die Transportvorrichtung 6 befördert nun die beiden Eierschachteln E zu einer Banderolenspendeeinheit 20, die am besten in der Figur 10 ersichtlich ist. Im hier dargestellten Beispiel wird von einem Stapel S jeweils die oberste Banderole mittels einem Saugkopf 21 angehoben und mit einer entsprechenden Kolbenzylindereinheit 22 unter dem angehobenen Flachstab 7 hindurch auf die bereitstehenden Eierschachteln gelegt. In der Figur 2 ist die hochgefahrene Position der Flachschiene 7 beziehungsweise der Transportvorrichtung 6 gezeigt, bevor die Banderolen über die Eierschachteln gelegt sind, während in Figur 3 die Banderolen B über die Schachteln hinweg dargestellt aufliegen. Hierzu sind beidseits parallel zur Flachschiene 4 Auflageflächen 23 vorhanden. Während die angehobene Position der Transportvorrichtung 6 beibehalten wird, fährt nunmehr der Flachstab 7 wieder zurück in Annahmerichtung, so dass nun jener Bereich des Flachstabes 7 über die Eierschachteln zu liegen kommt, der die Niederhalter 10 aufweist. Nun fährt die Hebeplatte 14 mit der gesamten Transportvorrichtung 6 nach unten und die Niederhalter 10 drücken die Banderolen B auf die Eierschachteln E. Diese Position zeigt die Figur 4. Das freie Ende des Flachstabes 7 ist nun bereit, zwei weitere hier nicht dargestellte Eierschachteln in einem nächsten Schritt zur Banderolenspendeeinheit hin zu transportieren. In der Figur 4 ist nun wiederum klar ersichtlich, dass sich die Transportvorrichtung 6 in der unteren Position befindet und entsprechend sind die Vertikalschienen 16 auch wieder deutlich erkennbar. In dieser Position ist die Kolbenzylindereinheit 18, mittels der die Hebeplatte 14 auf und nieder bewegt wird, gut erkennbar. Durch das Distanzelement 17, auf dem die Vertikalschienen 16 befestigt sind, ist die zweite Kolbenzylindereinheit 24, mittels welcher der Saugkopf 21 auf und ab bewegt wird, nur ansatzweise ersichtlich. Besser ist diese zweite Kolbenzylindereinheit im Vertikalschnitt nach Figur 10 zu erkennen.In a first step, as shown in FIG. 1, two ready-made egg boxes E are pushed onto the flat rail 4 by means of the transport device 6. Here are the boxes E on the work surface 3, not shown, or on an extension of the flat rail 4, also not shown here. The transport device 6 now conveys the two egg boxes E to a banderole donation unit 20, which is best seen in the figure 10. In the example shown here, the top banderole is lifted by a stack S by means of a suction head 21 and placed with a corresponding piston-cylinder unit 22 under the raised flat bar 7 on the egg boxes provided. FIG. 2 shows the raised position of the flat rail 7 or the transport device 6 shown before the bands are placed over the egg boxes, while in Figure 3, the bands B rest over the boxes shown away. For this purpose, on both sides parallel to the flat rail 4 bearing surfaces 23 are present. While the raised position of the transport device 6 is maintained, now moves the flat bar 7 back in the direction of acceptance, so that now that area of the flat bar 7 comes to rest on the egg boxes, which has the hold-10. Now moves the lifting plate 14 with the entire transport device 6 down and the hold down 10 press the bands B on the egg boxes E. This position shows the figure 4. The free end of the flat bar 7 is now ready, two other egg boxes not shown here in one next step to the banderole donation unit to transport. In FIG. 4, it is once again clear that the transport device 6 is in the lower position, and accordingly the vertical rails 16 are also clearly recognizable. In this position, the piston-cylinder unit 18, by means of which the lifting plate 14 is moved up and down, easily recognizable. By the spacer 17, on which the vertical rails 16 are fixed, the second piston-cylinder unit 24, by means of which the suction head 21 is moved up and down, only partially visible. This second piston-cylinder unit can be seen better in a vertical section according to FIG.

In einem nächsten, in der Figur 5 dargestellten Schritt, werden die beiden Eierschachteln E mit den darauf mittels den Niederhaltern des Flachstabes 7 klemmend gehaltenen Banderolen B weiter in Abschieberichtung transportiert zu einer vertikalen Falzstation 25. Diese wird gebildet durch eine Winkelplatte 26, die auf Vertikalschienen 27 auf und nieder fahrbar ist. Die Winkelplatte 26, an deren vertikalem Schenkel die Führungselemente, die mit den Schienen 27 in Verbindung stehen, angeordnet sind, hat einen horizontalen Schenkel 26'. An dessen Unterseite sind Leisten befestigt, an denen vertikal nach unten gerichtet Federplatten 28 montiert sind. Die Federplatten 28 haben auf ihrer inneren, zu den Eierschachteln gerichteten Flächen jeweils eine Andruckleiste 29.In a next step shown in FIG. 5, the two egg boxes E are transported further in the direction of removal to the vertical folding station 25 with the bands B held thereon by means of the hold-downs of the flat bar 7. This is formed by an angle plate 26 which is mounted on vertical rails 27 is mobile up and down. The angle plate 26, at the vertical leg of the guide elements, which are in communication with the rails 27, are arranged, has a horizontal leg 26 '. On the underside strips are attached to which vertically downward spring plates 28 are mounted. The spring plates 28 have on their inner, directed to the egg boxes surfaces each have a pressure bar 29th

In einem nächsten Schritt, wie er in der Figur 6 dargestellt ist, wird die Winkelplatte 26 der Falzstation 25 auf den Schienen 27 in die untere Position verschoben. In dieser Position ist nun auch die Kolbenzylindereinheit 30, mittels der diese Bewegung ausgeübt wird, ersichtlich. Während der Abwärtsbewegung faltet die vertikale Falzstation 25 die Banderole um die Eierschachtel herum nach abwärts, wobei die Andrückleiste 29 praktisch der Kontur der Eierschachtel entlang abwärts gleitet und dabei die Banderole straff anlegend führt. Die vertikale Falzstation 25 wird dabei soweit nach unten abgesenkt, dass die Andrückleiste 29 bis auf die mittige Kante anliegt und die Banderolenenden von dort vertikal nach unten ragen. Diese untere Position der Andrückleisten 29 ist in der Figur 10 am deutlichsten erkennbar.In a next step, as shown in Figure 6, the angle plate 26 of the folding station 25 is moved on the rails 27 in the lower position. In this position, now the piston-cylinder unit 30, by means of which this movement is exercised, can be seen. During the downward movement, the vertical folding station 25 folds the banderole around the egg box downwards, wherein the pressure bar 29 practically slides downwards along the contour of the egg box, thereby guiding the banderole tightly. The vertical folding station 25 is lowered so far down that the Andrückleiste 29 rests on the central edge and the band ends from there project vertically downwards. This lower position of the Pressure strips 29 can be seen most clearly in FIG.

In der in Figur 6 dargestellten Position erkennt man die nach unten ragenden Banderolenabschnitte und ersieht gleichzeitig, dass die horizontale Falzstation 31 noch nicht zum Einsatz gekommen ist. Während bei der vertikalen Falzstation beide Seiten links und rechts der Eierschachteln gleichzeitig bewegt werden, sind für die horizontale Falzstation zwei unabhängig voneinander betätigbare Teile vorhanden, die je für sich angetrieben sind. Sowohl die linke wie auch die rechte Teilstation der horizontalen Falzstation 31 weisen je zwei Federplatten 32 mit endständigen Andrückleisten 33 auf. Jede horizontale Teilfalzstation besteht aus einem winkelförmigen Schieber 34, an dem mittels Trägerleisten 35 die Federplatten 32 mit den Andruckleisten 33 befestigt sind.In the position shown in Figure 6 can be seen the downwardly projecting band portions and at the same time sees that the horizontal folding station 31 has not been used. While in the vertical folding station both sides of the left and right of the egg boxes are moved simultaneously, for the horizontal folding station two independently operable parts are present, which are ever driven for themselves. Both the left and the right sub-station of the horizontal folding station 31 each have two spring plates 32 with terminal Andrückleisten 33. Each horizontal Teilfalzstation consists of an angle-shaped slide 34, on which by means of carrier strips 35, the spring plates 32 are attached to the Andruckleisten 33.

Mittels einer ersten Kolbenzylindereinheit 36 und einer zweiten Kolbenzylindereinheit 37 lässt sich die linke beziehungsweise rechte horizontale Teilfalzstation bewegen. Die beiden Kolbenzylindereinheiten sind in der Figur 6 nur teilweise ersichtlich, während sie in der Figur 4 deutlich erkennbar sind, weil die nach unten ragenden Teilabschnitte der Banderolen hier die Sicht nicht verdecken. Mittels den beiden Kolbenzylindereinheiten 36,37 wird erst der eine Banderolenabschnitt unter der Flachschiene 4 hindurch umgebogen und danach mittels der zweiten Kolbenzylindereinheit 37 die zweite Lasche über die erste hinweg umgebogen.By means of a first piston-cylinder unit 36 and a second piston-cylinder unit 37, the left or right horizontal Teilfalzstation can be moved. The two piston-cylinder units are only partially visible in FIG. 6, while they are clearly visible in FIG. 4, because the downwardly projecting sections of the bands do not hide the view here. By means of the two piston-cylinder units 36, 37, only one banding section under the flat rail 4 passes through bent over and then bent over the second tab over the first time by means of the second piston-cylinder unit 37.

Bei der Falzbewegung drücken die entsprechenden Andruckleisten 33 einerseits die entsprechende Lasche der Banderole an die Unterseite der Flachschiene und andererseits drückt die nachfolgend betätigte Federplatte 32 mit der entsprechenden Andruckleiste 33 den andersseitigen Abschnitt der Banderole auf den bereits umgefalteten Banderolenabschnitt und führt dabei einen Pressdruck auf die Klebestelle aus, die zwischen diesen beiden Banderolenenden vorhanden ist.During the folding movement press the corresponding Andruckleisten 33 on the one hand the corresponding tab of the band to the underside of the flat rail and on the other hand pushes the subsequently actuated spring plate 32 with the corresponding Andruckleiste 33 the other side portion of the band on the already folded band portion and thereby performs a pressing pressure on the splice from, which is present between these two Banderolenenden.

Der entsprechende Klebestreifen erfolgt mittels einer Klebstoffauftragstation 40. Diese Klebstoffauftragstation 40 ist lediglich in der Figur 10 erkennbar und ist in einem Durchbruchbereich der Auflagefläche 23 angeordnet. Die Klebung erfolgt nachdem die Banderole bereits quer über die Eierschachtel hinweg auf diese aufgelegt und mit dem Niederhalter 10 in kraftschlüssiger Verbindung mit der Eierschachtel hält. Während die Vorschubvorrichtung 6 nun die Eierschachtel zur Ausstossrichtung hin bewegt, klebt die Klebstoffauftragstation Klebstoff auf die Banderole einseitig auf. Da diese Auftragung auf der Unterseite der Banderole erfolgt, muss in der horizontalen Falzstation, wie in Figur 10 dargestellt, erst die linke Teilstation das eine Banderolenende umbiegen, bevor das mit Klebstoff versehene Ende umgebogen und auf das bereits umgebogene Ende aufgelegt und angedrückt wird.The corresponding adhesive strip is effected by means of an adhesive application station 40. This adhesive application station 40 can only be seen in FIG. 10 and is arranged in a breakthrough region of the support surface 23. The bonding takes place after the banderole already laid across the egg box on this time and holds with the hold-10 in frictional connection with the egg box. While the advancing device 6 now moves the egg box toward the ejection direction, the adhesive application station adhesively adheres adhesive to the band on one side. Since this application is carried out on the underside of the band, in the horizontal folding station, as shown in Figure 10, only the left sub-station must bend the one band end before the provided with adhesive Bent over and placed on the already bent end and pressed.

Neben der hier dargestellten Version, bei der die Klebstoffauftragstation 40 unterhalb der Auflagefläche 23 angeordnet ist, liesse sich selbstverständlich die Klebstoffauftragstation auch oberhalb dieser Auflagefläche 23 anordnen. In diesem Fall müsste erst jenes Banderolenende umgefaltet werden, welches den Klebstoff trägt und nachher das gegenüber liegende Banderolenende über diese Klebstelle hinweg angedrückt werden. Die Klebstoffauftragstation kann mit einer Auftragsrolle ausgestaltet sein oder, wie hier bevorzugt, ähnlich einem Tintenstrahldrucker arbeiten. Selbstverständlich kommen auch andere bekannte Klebstoffauftragesysteme in Frage. In der Figur 7 sind die beiden Schieber 34 nach innen bewegt und entsprechend sind nun die horizontalen Führungsschienen 38 ersichtlich, auf denen die winkelförmigen Schieber 34 hin und her bewegt werden.In addition to the version shown here, in which the adhesive application station 40 is arranged below the support surface 23, it goes without saying that the adhesive application station can also be arranged above this support surface 23. In this case, only that Banderolenende would have to be folded over, which carries the adhesive and subsequently pressed the opposite band end over this adhesive point away. The adhesive application station may be configured with a job roll or, as preferred here, operate similarly to an ink jet printer. Of course, other known adhesive application systems come into question. In FIG. 7, the two slides 34 are moved inwards and, accordingly, the horizontal guide rails 38 are now visible, on which the angle-shaped slides 34 are moved back and forth.

In einem nächsten Schritt, der in der Figur 8 dargestellt ist, werden nun die vertikale Falzstation 25 sowie die Transportvorrichtung 6 nach oben bewegt, wobei dies einerseits mittels der Kolbenzylindereinheit 30 und andererseits mittels der Kolbenzylindereinheit 18 erfolgt. In der oberen Position fährt der Flachstab 7 mit den Schiebern 8 und 9 wieder in die Aufnahmeposition zurück, um dann in einem nächsten Schritt, wie in der Figur 9 dargestellt, wiederum abgesenkt zu werden und in Ausstossrichtung vorgeschoben zu werden. Dabei stösst der vordere endseitige Schieber 8 die Eierschachteln von der Flachschiene 4, wobei gleichzeitig diese Flachschiene 4 aus der verklebten Banderole B herausgezogen wird. Die Flachschiene 4 mit der Führungsrippe 5 bewegt sich dabei natürlich nicht. Die Flachschiene 4 liegt an ihrem freien, fliegenden Ende auf einer Andrückrolle 41 auf, die in einer Konsole 42 gelagert ist. Die nun fertig banderolierten Eierschachteln E lassen sich nun auf der Arbeitsplatte 3 senkrecht von der Fortbewegungsrichtung der Banderoliermaschine mittels einem Schieber 43 wegstossen. Diese Eierschachteln sind nun fertig für den Versand.In a next step, which is shown in FIG. 8, the vertical folding station 25 and the transport device 6 are now moved upwards, this taking place on the one hand by means of the piston-cylinder unit 30 and on the other hand by means of the piston-cylinder unit 18. In the upper position of the flat bar 7 moves back with the sliders 8 and 9 in the receiving position back to then in a next step, as shown in the figure 9 again to be lowered and advanced in the ejection direction. In this case, the front end-side slider 8 pushes the egg boxes from the flat rail 4, wherein at the same time this flat rail 4 is pulled out of the bonded B band B. Of course, the flat rail 4 with the guide rib 5 does not move. The flat rail 4 is located at its free, flying end on a pressure roller 41 which is mounted in a bracket 42. The now banderolierten egg boxes E can now be pushed away on the worktop 3 perpendicular to the direction of movement of the banding machine by means of a slider 43. These egg boxes are now ready for shipping.

Trotz der Kleinheit und Kompaktheit der Maschine lassen sich mit derselben relativ hohe Leistungen erzielen. Selbstverständlich kann die Maschine zusätzlich mit einem Tintenstrahldrucker ausgerüstet werden, der entweder im Bereich der Zuführung der Banderolen angeordnet ist oder in der Verlängerung der Flachschiene 4, wo die Banderole beschriftet werden kann, während sie bereits um die Eierschachtel gelegt ist.Despite the small size and compactness of the machine can be achieved with the same relatively high performance. Of course, the machine can be additionally equipped with an inkjet printer, which is arranged either in the region of the supply of the bands or in the extension of the flat bar 4, where the band can be labeled while it is already placed on the egg box.
