Description

Die vorliegende Erfindung bezieht sich auf eine Einrichtung gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to a device according to the preamble of claim 1.

Eine Einrichtung dieser Art ist aus der CA-PS 1 288 990 bekannt. In deren Zuschnittmagazin sind die flachen Verpackungszuschnitte aus Wellkarton in einer in Förderrichtung der Förderstrecke geneigten Schräglage gehalten. Der jeweils unterste Zuschnitt dieses schräg liegenden Zuschnittstapels wird von der Anlegeeinrichtung an einem den Verpackungsboden bildenden Abschnitt erfasst und auf einer im wesentlichen elliptischen Bahn zwischen die Mitnehmer eines Mitnehmerpaares auf die Förderstrecke aufgelegt und dabei so lange festgehalten, bis die beiden Mitnehmer die Verpackung zu einer abfüllfähigen Zwischenform vorgeformt haben.A device of this type is known from CA-PS 1 288 990. The flat packaging blanks are in their blank magazine made of corrugated cardboard in a conveying direction of the conveyor line inclined inclined. The bottom cut this sloping stack of blanks is used by the feeder on a section forming the packaging base captured and on an essentially elliptical orbit between the carriers of a pair of carriers placed on the conveyor line and held on until the two drivers the packaging is preformed into a fillable intermediate form to have.

Im schräg liegenden Zuschnittstapel im Magazin ist die Luft zwischen den Zuschnitten herausgepresst. Wird der unterste Zuschnitt von der Anlegeeinrichtung abgezogen, entsteht zwischen ihm und dem anliegenden Zuschnitt ein Vakuum. Dadurch besteht die Gefahr, dass er mit dem untersten Zuschnitt von der Anlegeeinrichtung mit aus dem Magazin herausgezogen wird. Bei solchen Fehlablagen muss die Einrichtung mitsamt der anschliessenden Verpackungsmaschine gestoppt und der zuviel abgezogene Zuschnitt von Hand entfernt werden. Zur Vermeidung solcher Fehlablagen sind im Bereich des Magazins verstellbare Dorne erforderlich, die mit ihren Spitzen seitlich geringfügig in den zweiten Zuschnitt einstechen und ihn am Mitgerissenwerden durch den ersten Zuschnitt hindern. Das optimale Einstellen dieser Dorne muss nach einer Format- oder Kartonqualitätsänderung der Zuschnitte bei laufender Maschine erfolgen, was hohe Verlustzeiten zur Folge hat.There is air in the slanted stack of blanks in the magazine pressed out between the blanks. Will be the bottom one Cutting removed from the feeder arises between a vacuum for him and the adjacent blank. As a result the risk that he is with the lowest cut from the feeder is pulled out of the magazine. In such Incorrect filing must be done by the facility together with the subsequent one Packaging machine stopped and the cut-off cut too much be removed by hand. To avoid such incorrect filing adjustable mandrels are required in the area of the magazine, those with their tips slightly to the side in the second Pierce the cut and be carried away by the prevent the first cut. The optimal setting of these mandrels must be done after changing the format or carton quality of the blanks done while the machine is running, resulting in high loss times has the consequence.

Ein weiterer Nachteil dieser bekannten Einrichtung liegt im konstruktiven Aufwand der erforderlich ist, um die Sauggreifer der Anlegeeinrichtung auf einer elliptischen Bahn zu bewegen.Another disadvantage of this known device is design effort required to the suction cup the application device to move on an elliptical path.

Die vorliegende Erfindung stellt sich daher die Aufgabe, an einer Einrichtung der eingangs genannten Art die genannten Nachteile zu beseitigen.The present invention therefore has as its object a device of the type mentioned the disadvantages mentioned to eliminate.

Erfindungsgemäss wird diese Aufgabe gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.According to the invention, this object is achieved by the characterizing Features of claim 1.

Durch die erfindungsgemässe Lösung kann ungehindert Luft zwischen die im Magazin stehenden und beim Einlauf ins Magazin auffächernden Zuschnitte eintreten, wodurch die Gefahr des Mitreissens des zweitvordersten Zuschnitts gebannt ist. Weiter sind Anpassungen der Sauggreifer an andere Zuschnittformate vergleichsweise einfach und rasch durchführbar.Air can flow freely through the solution according to the invention between those in the magazine and when entering the magazine fan-out cuts occur, which increases the risk of entrainment of the second front blank is banned. Are further Adaptations of the suction pads to other cutting formats comparatively easy and quick to do.

Die mit Bezug auf die Fig. 3 und 4 beschriebene Einrichtung dient dem Vorformen einer Verpackung 1 (Fig. 1) zu einer abfüllfähigen Zwischenform.The device described with reference to FIGS. 3 and 4 serves the preforming of a packaging 1 (FIG. 1) into a fillable one Intermediate form.

Die Verpackung 1 besteht aus einem Boden B, einer Frontwand F, einer Rückwand R, einem Deckel D und daran anschliessenden Seitenlappen S sowie einem an der Rückwand R angebrachten Verschlusslappen V. Die miteinander verleimten Seitenlappen S bilden die Seitenwände, die - je nach Grösse der Seitenlappen - offen oder geschlossen sein können. Bei der fertigen Verpackung ist auch der Verschlusslappen V mit dem Deckel D verleimt. Alle diese Verpackungsteile sind einstückig aus einem flachen Zuschnitt 2 (Fig. 2) gefertigt und nur durch Falzlinien oder Falzrillen 3 und 4 bzw. durch Ausklinkungen 5 voneinander getrennt. Für das Füllen der Verpackung 1 wird diese vorerst in eine Zwischenform vorgeformt, indem einerseits die Frontwand F mit dem Deckel D und anderseits die Rückwand R mit dem Verschlusslappen V um die entsprechenden Falzlinien 3 rechtwinklig nach oben gefalzt werden. Die Seitenlappen S stehen bei der vorgeformten Verpackung noch koplanar vom angrenzenden Schachtelabschnitt B, F, R bzw. D ab. In die zu dieser Zwischenform vorgeformte Verpackung wird das Verpackungsgut von der Seite auf den Boden B aufgeschoben und anschliessend werden die übrigen Teile zur Bildung der fertigen Verpackung umgefalzt und miteinander verleimt. The package 1 consists of a bottom B, a front wall F, a rear wall R, a lid D and adjoining side tabs S and a flap attached to the rear wall R. V. The side tabs S glued together form the Side walls that - depending on the size of the side flaps - open or can be closed. With the finished packaging is also the sealing flap V is glued to the cover D. All these Packaging parts are in one piece from a flat blank 2 (Fig. 2) manufactured and only by fold lines or fold grooves 3rd and 4 or separated by notches 5. For the Filling the packaging 1 is initially in an intermediate form preformed by the front wall F with the cover D and on the other hand the rear wall R with the flap V around the corresponding fold lines 3 are folded upwards at right angles. The side tabs S are still in the preformed packaging coplanar from the adjacent box section B, F, R or D. That is in the preformed packaging for this intermediate form Packaged goods pushed from the side onto the floor B and The remaining parts are then used to form the finished parts Packaging folded and glued together.

Für das periodische Anlegen von Zuschnitten 2 werden diese in einem Magazin 6 senkrecht auf einem in der Höhe einstellbaren Boden 7 bereit gestellt. Eine obere und eine untere Rückhalteleiste 8 hindern mit geringem Widerstand den vordersten Zuschnitt 2 am Herausfallen aus dem Magazin 6. Dieses wird laufend mit Zuschnitten von einem schräg abwärtslaufenden und in seiner Neigung verstellbaren Förderband 9 beschickt, wobei diese nachgeförderten Zuschnitte beim Punkt 10 zuerst zur Anlage mit den im Magazin befindlichen Zuschnitten kommen. Durch das Förderband 9 werden sie dann am Fussende aufgefächert, so dass Luft zwischen die einzelnen Zuschnitte treten kann, bevor sie auf dem Boden 7 mindestens näherungsweise senkrecht aufgereiht werden.For the periodic creation of blanks 2, these are in a magazine 6 vertically on a height adjustable Floor 7 provided. An upper and a lower retaining bar 8 prevent the front cut with little resistance 2 falling out of the magazine 6. This is continuously with Cut from an obliquely downward and in its Tilt adjustable conveyor belt 9, which is re-conveyed Cuts at point 10 first to the plant with the blanks in the magazine. Through the conveyor belt 9 they are then fanned out at the foot end so that there is air between the individual blanks can kick before they are on the floor 7 be lined up at least approximately vertically.

An das Magazin 6 schliesst eine Förderstrecke 11 an, die die zu einer Zwischenform vorgeformten Zuschnitte 2 zu den nachfolgenden Abfüllstationen einer Verpackungsmaschine abfördert. Die Förderstrecke 11 wird im wesentlichen durch ein endloses, von einem nicht dargestellten Motor angetriebenes Kettenpaar 12 gebildet, dessen fördernder und gezogener Trum sich in einer Förderebene 13 in Richtung des eingezeichneten Pfeiles bewegt. Das Kettenpaar 12 ist um zwei Umlenkräder 14 geführt, die frei drehfest auf einer frei drehbar gelagerten Welle 15 sitzen und das mit regelmässig beabstandeten Mitnehmerpaaren 16 besetzt ist. Jedes Mitnehmerpaar 16 weist in Förderrichtung vorangehende Mitnehmer 16' und nachlaufende Mitnehmer 16'' auf, die auf den einander zugewandten Seiten mit zur Förderebene 13 rechtwinklig orientierten Flanken versehen sind. A conveyor section 11 connects to the magazine 6 and closes an intermediate form preformed blanks 2 to the following Fills filling stations of a packaging machine. The conveyor line 11 is essentially an endless one Motor driven chain pair 12, not shown, formed whose promoting and drawn strand is in one level 13 moved in the direction of the arrow. The pair of chains 12 is guided around two deflection wheels 14, which are free to rotate sit on a freely rotatable shaft 15 and with regularly spaced driver pairs 16 is occupied. Each Driver pair 16 has previous drivers in the conveying direction 16 'and trailing driver 16' 'on each other facing sides with the conveyor plane 13 oriented at right angles Flanks are provided.

Längs einer Einlaufstrecke 17 treten die Mitnehmerpaare 16 während des Umlaufs der Mitnehmer 16', 16'' um die Umlenkräder 14 vom unteren Kettentrum auf die Förderebene 13 und übernehmen, wie später beschrieben, einen Zuschnitt 2. Die Welle 15 ist in zwei senkrechten, parallelen Platten 19, zwischen denen das Kettenpaar 12 umläuft, drehbar gelagert. Auf den einander abgewandten Plattenseiten sitzt je eine Rolle 20 drehfest auf der Welle 15, auf deren Umfang gummielastische Ringe 21 nach Art einer Vollgummibereifung aufgesetzt sind. Der Aussendurchmesser der Ringe 21 ist etwas grösser als der Teilkreisdurchmesser der Kettenumlenkräder 14, so dass die Umfangsgeschwindigkeit der Ringe 21 grösser, vorzugsweise zirka 5 % bis 10 % grösser als die Fördergeschwindigkeit des Kettenpaars 12 ist.The driver pairs 16 occur along an inlet path 17 during of the rotation of the drivers 16 ', 16' 'around the deflection wheels 14 from lower chain center to the conveyor level 13 and take over how described later, a blank 2. The shaft 15 is in two vertical, parallel plates 19, between which the pair of chains 12 rotates, rotatably mounted. On the opposite A roller 20 is seated on the shaft 15 in a rotationally fixed manner, on the circumference of rubber-elastic rings 21 in the manner of solid rubber tires are put on. The outside diameter of the rings 21 is slightly larger than the pitch circle diameter of the chain deflection wheels 14 so that the peripheral speed of the rings 21st larger, preferably about 5% to 10% larger than the conveying speed of the chain pair 12.

Mit geringem Abstand über den Rollen 20 ist an den Platten 19 ein die Rollen 20 überdeckendes Leitblech 23 befestigt, welches parallel zur Förderebene 13 orientiert ist und das auf seiner Unterseite eine glatte Gleitfläche bildet. Die Leitbleche 23 beginnen kurz vor der Welle 15 und enden nahe oder beim Ende des Einlaufbereichs 17.A short distance above the rollers 20 is on the plates 19th attached a guide plate 23 covering the rollers 20, which is oriented parallel to the funding level 13 and that on his Underside forms a smooth sliding surface. The baffles 23 start shortly before wave 15 and end near or at the end of Entry area 17.

Weiter weist die Einrichtung einen Exzenterantrieb 24 auf, der eine Schwinge 25 in Förderrichtung zwischen den gezeichneten Endlagen hin und her verschwenkt. Die Schwinge 25 ist durch zwei Lenker 26 je mit einem Schlitten 27 verbunden, die auf zur Förderrichtung parallelen Führungen 28 geradlinig verschiebbar sind. Furthermore, the device has an eccentric drive 24 which a rocker 25 in the conveying direction between the drawn End positions pivoted back and forth. The rocker 25 is through two Handlebar 26 each connected to a carriage 27 which on the conveying direction parallel guides 28 are linearly displaceable.

Die Führungen 28 sind an den Platten 19 auf den einander abgewandten Seiten befestigt. In jedem der beiden Schlitten 27 ist frei drehbar ein Rohr 29 gelagert, auf dem drehfest ein Ritzel 30 sitzt. Vom Rohr 29 querab führen drei winkelförmige Rohrstücke 31, die am freien Ende gummielastische Saugnippel 32 tragen, die einen Sauggreifer bilden. Das Rohr 29 ist über ein nicht dargestelltes, steuerbares Ventil mit einer ebenfalls nicht dargestellten Unterdruckquelle verbunden, so dass die Saugnippel 32 im Maschinentakt wahlweise mit Vakuum oder Normaldruck beaufschlagbar sind.The guides 28 are on the plates 19 facing away from each other Sides attached. There is 27 in each of the two slides A tube 29 rotates freely, on which a pinion is fixed against rotation 30 sits. Three angular pipe sections lead from the pipe 29 transversely 31, which carry rubber-elastic suction nipples 32 at the free end form a suction pad. The tube 29 is over a, not shown, controllable valve with a likewise not shown Vacuum source connected so that the teat 32 Vacuum or normal pressure can be applied in the machine cycle are.

Das Ritzel 30 kämmt mit einer Zahnstange 33, welche fest mit der Kolbenstange eines hydraulisch oder pneumatisch antreibbaren, auf dem Schlitten 27 befestigten Kolbenantriebs 34 verbunden ist. Wird der Kolbenantrieb 34 von einem Medium beaufschlagt, dreht sich das Rohr 29, wie in Fig. 3 angedeutet, um 90°.The pinion 30 meshes with a rack 33 which is fixed to the Piston rod of a hydraulically or pneumatically drivable, on the slide 27 attached piston drive 34 is connected. If the piston drive 34 is acted upon by a medium, rotates the tube 29, as indicated in Fig. 3, by 90 °.

Die beschriebene Einrichtung funktioniert wie folgt. Das kontinuierlich umlaufende Kettenpaar 12 bringt mit jedem Maschinentakt ein Mitnehmerpaar 16 in den Einlaufbereich 17. Während der vorangehende Mitnehmer 16' die Förderebene 13 erreicht, erfassen die Saugnippel 32 in der in Fig. 3 mit ausgezogenen Strichen gezeigten Stellung (in der sie mit Vakuum beaufschlagt sind) den im Magazin 6 vordersten Zuschnitt 2 im Bereich der Frontwand F und vorzugsweise auch des Deckels D. Der Exzenterantrieb 24 verschiebt nun den Schlitten 27 - bevor der nachlaufende Mitnehmer 16'' die Einlaufstrecke 17 erreicht - in die andere Endlage. Die Saugnippel 32 ziehen dabei die Frontwand F und den Deckel D des erfassten Zuschnitts 2 in Förderrichtung ab, wobei die erfassten Zuschnittabschnitte F und D ihre senkrechte Ausrichtung behalten. Die übrigen, im Magazin 6 unterhalb der Förderebene 13 befindlichen Zuschnittabschnitte B, R, V mit ihren angrenzenden Seitenlappen S werden dabei nachgezogen, wobei sie auf die Rollen 20 auftreffen (in Fig. 3 Stellung 35) und durch diese während der weiteren Bewegung in die Förderebene 13 hochgeschwenkt werden (Pfeil 36). Anschliessend werden die vom Boden B seitlich wegragenden Seitenlappen S zwischen die Unterseite der Leitbleche 23 und die Rollen 20 gezogen und dort durch die elastische Verformung der Ringe 21 von diesen (wie vorerwähnt) mit grösserer Geschwindigkeit als die Fördergeschwindigkeit des Kettenpaars 12 reibschlüssig angetrieben bis die Frontwand F des Zuschnitts 2 am vorangehenden Mitnehmer 16' ansteht. Der im wesentlichen mit gleicher Geschwindigkeit wie die Umfangsgeschwindigkeit der Ringe 21 angetriebene Schlitten 27 erreicht die andere Endlage (Stellung 37) nach der Übernahme des Zuschnitts 2 durch die Rollen 20 aber spätestens, wenn die Rollen 20 den Zuschnitt 2 in Anschlag mit dem vorangehenden Mitnehmer 16 gebracht haben. In dieser Schlittenendlage werden die Saugnippel 32 mit Normaldruck beaufschlagt, so dass sie den Zuschnitt 2 freigeben; gleichzeitig oder anschliessend werden sie durch eine Aktivierung des Kolbenantriebs 34 um 90° nach aussen aus dem Förderweg des Zuschnitts 2 heraus geschwenkt. Anschliessend verschiebt sich der Schlitten 27 in die andere Endlage und der beschriebene Arbeitsablauf wiederholt sich.The setup described works as follows. That continuously revolving chain pair 12 brings with every machine cycle a pair of drivers 16 in the inlet area 17. During the previous Driver 16 'reaches the conveying level 13 the teat 32 in Fig. 3 with solid lines shown position (in which they are subjected to vacuum) in magazine 6 the front blank 2 in the area of the front wall F and preferably also the cover D. The eccentric drive 24 moves now the carriage 27 - before the trailing driver 16 '' reaches the inlet section 17 - to the other end position. The Suction nipples 32 pull the front wall F and the cover D of the detected blank 2 in the conveying direction, the detected Cut sections F and D keep their vertical orientation. The rest, located in the magazine 6 below the conveyor level 13 Cutting sections B, R, V with their adjacent side tabs S are tightened, whereby they are on the rollers 20th meet (in Fig. 3 position 35) and by this during the further movement can be pivoted up into the conveyor plane 13 (Arrow 36). Then those that protrude laterally from floor B are removed Side tabs S between the underside of the baffles 23 and the rollers 20 pulled and there by the elastic deformation of the rings 21 of these (as mentioned above) with larger ones Speed as the conveyor speed of the chain pair 12 frictionally driven until the front wall F of the blank 2 is present at the preceding driver 16 '. The essentially with same speed as the peripheral speed of the Rings 21 driven carriage 27 reaches the other end position (Position 37) after the takeover of the blank 2 by the Rolls 20 at the latest when the rolls 20 cut 2 in Have brought stop with the previous driver 16. In this slide end position, the teat 32 with normal pressure applied so that they release the blank 2; at the same time or then they are activated by activating the piston drive 34 90 ° outwards from the conveying path of the blank 2 pivoted out. The sledge then moves 27 in the other end position and the workflow described repeated.

Es kann zweckmässig sein, mit beiden Schlitten 27 bzw. mit den Saugnippeln 32 je eine fingerförmige, flache Niederhalteplatte 40 mitzubewegen, die je um eine zu dem Rohr 29 parallele Achse schwenkbar sind. Die Niederhalteplatten 40 liegen in der Förderebene 13. Ihre Oberseite liegt geringfügig tiefer als die Unterseite der Leitbleche 23. In der in Fig. 3 mit ausgezogenen Strichen gezeigten Stellung der Saugnippel 32 werden die Niederhalteplatten 40 in die in der Förderebene 13 liegenden Ausklinkungen 5 des vordersten Zuschnitts 2 geschwenkt. In diesen Ausklinkungen verbleiben sie und folgen während der Ablage des Zuschnitts 2 den Saugnippeln 32 bis diese die Stellung 35 überschritten haben und die unteren Kanten der Ausklinkungen 5 unter den Leitblechen 23 liegen und von den Rollen 20 erfasst werden. In diesem Moment werden sie aus dem Förderweg des Zuschnitts herausgeschwenkt und kehren mit den Saugnippeln 32 in die in Fig. 3 gezeigte Stellung zurück. Durch die Niederhalteplatten 40 werden die unteren Kanten der in der Förderebene 13 liegenden Ausklinkungen formschlüssig vom Magazin 6 weg bis unter die Leitbleche 23 geführt, wodurch auch sich stark verwerfende Zuschnitte 2 zuverlässig in den Wirkbereich der Rollen 20 gebracht werden.It may be appropriate to use both carriages 27 or Suction cups 32 each have a finger-shaped, flat hold-down plate 40 to move, each around an axis parallel to the tube 29 are pivotable. The hold-down plates 40 lie in the conveying plane 13. Your top is slightly lower than the bottom of the baffles 23. In the extended in Fig. 3 Dashed position of the teat 32, the hold-down plates 40 in the notches lying in the conveyor plane 13 5 of the front blank 2 pivoted. In these notches they remain and follow while filing the Cut 2 the teats 32 until they exceed position 35 have and the lower edges of the notches 5 under the guide plates 23 are located and are captured by the rollers 20. At this moment, they are cut out of the funding path pivoted out and return with the teat 32 in Fig. 3 position shown back. Through the hold-down plates 40 the lower edges of the lying in the conveyor plane 13 Notches form-fit from magazine 6 to below Baffles 23 out, which also strongly warping Blanks 2 reliably in the effective range of the rolls 20 to be brought.

Unmittelbar nach dem Erfassen der Seitenlappen S des Bodens B durch die Rollen 20 (Stellung 37) bewegt sich der nachlaufende Mitnehmer 16' des einlaufenden Mitnehmerpaars 16 von unten auf die Förderebene 13. Dabei schwenkt er die Rückwand R mit ihren Seitenlappen S und dem Verschlusslappen V um die entsprechende Falzlinie 3 nach oben bis sie an seiner vorangehenden Flanke anliegt und dabei rechtwinklig zur Förderebene 13 orientiert ist. Während dieses Vorgangs werden die Seitenlappen S des Bodens B durch die Leitbleche 23 niedergehalten, so dass sich der Boden B in der Förderebene 13 vorwärts bewegt. Mit dem Hochschwenken der Rückwand R ist das Vorformen der Verpackung zu einer abfüllfähigen Zwischenform beendet und die vorgeformte Verpackung wird, sozusagen zwischen den Mitnehmern 16' und 16'' eines Mitnehmerpaars 16 eingeklemmt zu einer nachfolgenden Füllstation transportiert.Immediately after capturing the side tabs S of the bottom B the trailing one moves through the rollers 20 (position 37) Driver 16 'of the incoming driver pair 16 from below the conveyor level 13. He swings the rear wall R with their Side flap S and the flap V around the corresponding Fold line 3 up until it is on its leading flank is applied and oriented at right angles to the conveyor level 13 is. During this process, the side flaps S of the bottom B held down by the baffles 23 so that the bottom B moved forward in the conveyor plane 13. With swinging up the rear wall R is the preforming of the packaging into a fillable one Intermediate form ends and the preformed packaging is so to speak between the carriers 16 'and 16' 'of a pair of carriers 16 clamped transported to a subsequent filling station.

Da die Rollen 20 nicht nur die Seitenlappen S des Bodens B antreiben sondern auch die den Zuschnittabschnitten F und D nachfolgenden Zuschnittabschnitte B, R und V im Sinne des Pfeiles 36 hochschwenkt, haben sie zusätzlich die Funktion eines Leitorgans, das die vom Boden B nachgezogenen Zuschnittabschnitte R und V in eine Lage führen, in der sie vom nachlaufenden Mitnehmerpaar 16'' zuverlässig erfasst und dann in die Vertikale nach oben geschwenkt werden können.Since the rollers 20 not only drive the side tabs S of the bottom B. but also those following the cutting sections F and D Blank sections B, R and V in the direction of arrow 36 swings up, they also have the function of a guide organ, that the redrawn from the bottom B cut sections R and V in lead in a position in which they follow from the trailing pair of drivers 16 '' reliably detected and then pivoted upwards into the vertical can be.

Die Anlegeeinrichtung kann konstruktiv auch anders ausgebildet sein. Wesentlich ist, dass die Greifer 32 die Frontwand F des Zuschnitts 2 in senkrechter Ausrichtung zur Förderebene 2 und in Förderrichtung der Förderstrecke 11 übergeben und dass der Verpackungsboden B während des Vorformens des Zuschnitts 2 zu einer abfüllfähigen Zwischenform formschlüssig in der Förderebene 13 gehalten wird. Anstelle der Leitbleche 23 können andere Niederhalteorgane wie Rollen oder dgl. vorgesehen werden.The application device can also be designed differently be. It is essential that the gripper 32 the front wall F of the Blank 2 in a vertical orientation to the conveyor level 2 and in Direction of conveyance of the conveyor line 11 passed and that the packaging floor B during preforming the blank 2 into one fillable intermediate form positively in the conveying plane 13 is held. Instead of the guide plates 23, other hold-down devices can be used such as roles or the like.
