Description

Die Erfindung betrifft eine Vorrichtung zum Falten von ebenen Materialstreifen, insbesondere von Zuschnitten aus Papier oder Karton. - Bei - dem Materialstreifen mag es sich um Kartonstreifen handeln, die von der Rolle abgezogen, gerillt, bedruckt, gestanzt und abgetrennt worden sind und mittels der Vorrichtung zu Faltschachteln aufgerichtet werden. Die Materialstreifen können beispielsweise aber auch bedruckte einlagige oder mehrlagige Papierstreifen sein, die mittels der Vorrichtung C-förmig oder ringförmig gefaltet und als Beilagedrucksachen in oben offene Verpackungen eingelegt werden.The invention relates to a device for folding flat strips of material, in particular blanks made of paper or cardboard. - The material strip may be cardboard strips which have been pulled off the roll, grooved, printed, punched and separated and are erected into folding boxes by means of the device. The material strips can, for example, also be printed single-ply or multi-ply paper strips, which are folded in a C-shape or in a ring by means of the device and inserted as supplementary printed matter in open packaging.

Aus der Praxis bekannte Vorrichtungen für die beschriebenen Anwendungen weisen translatorisch bewegbare Stempel auf, die in feste Faltwerkzeuge ein- und ausfahren. Zusätzlich können bewegliche Faltwerkzeuge zugeordnet sein. Die bekannten Vorrichtungen arbeiten taktweise, wobei ein an den Faltwerkzeugen positionierter Materialstreifen durch einen einfahrenden Stempel geformt und anschließend von diesem abgestreift wird. Der Formstempel wird zurückbewegt und ein neuer Materialstreifen zu Beginn des nächsten Arbeitstaktes an den Faltwerkzeugen positioniert. Die Fertigungsgeschwindigkeit ist verbesserungsbedürftig. Werden die Vorrichtungen zum Falten der Materialstreifen in einer Maschinenanlage aus mehreren, in Stationen arbeitenden Maschinen eingesetzt, aus denen nach einem "just in time"-Konzept bedruckte Faltschachteln hergestellt werden, Beipackzettel bedruckt, gefaltet und in die Faltschachteln eingelegt werden sowie die Faltschachteln schließlich mit Gegenständen befüllt und versandfertig verschlossen werden, erweisen sich die bekannten Vorrichtungen zum Aufrichten der Faltschachteln sowie zum Einlegen der Beipackdrucksachen als zeitkritische, die Durchsatzleistung der Maschinenanlage insgesamt limitierende Stationen.Devices known from practice for the described applications have translationally movable stamps which move in and out of fixed folding tools. Movable folding tools can also be assigned. The known devices work in cycles, a material strip positioned on the folding tools being shaped by an retracting stamp and then being stripped off by the latter. The form stamp is moved back and a new strip of material is positioned on the folding tools at the beginning of the next work cycle. The production speed is in need of improvement. Are the devices used to fold the material strips in a machine system made up of several machines working in stations, from which folding boxes are printed according to a "just in time" concept are produced, package inserts are printed, folded and placed in the folding boxes, and the folding boxes are finally filled with objects and sealed ready for dispatch, the known devices for erecting the folding boxes and for inserting the package inserts prove to be time-critical stations that limit the throughput of the machine as a whole.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Falten von ebenen Materialstreifen, insbesondere von Zuschnitten aus Papier oder Karton, anzugeben, mit der pro Zeiteinheit eine große Anzahl von Materialstreifen gefaltet werden können.The invention has for its object to provide a device for folding flat strips of material, in particular blanks made of paper or cardboard, with which a large number of strips of material can be folded per unit of time.

Gegenstand der Erfindung und Lösung dieser Aufgabe ist eine Vorrichtung zum Falten von ebenen Materialstreifen, insbesondere von Zuschnitten aus Papier oder Karton, - mit

  • mindestens einem endlos umlaufenden Riemen,
  • an den Riemen angeschlossenen Formzapfen,
  • einer Faltstation mit maschinenfesten, entlang der Umlaufbahn der Formzapfen angeordneten Faltwerkzeugen,
  • einer Einrichtung zur Positionierung von Materialstreifen in der Umlaufbahn der Formzapfen quer zu deren Bewegungsrichtung und
  • einer Abstreifstation mit einer Einrichtung zum Abstreifen der an den Formzapfen umgefalteten Materialstreifen,
wobei der Riemen kontinuierlich umläuft und die Einrichtung zum Positionieren der Materialstreifen, die Faltstation sowie die Abstreifstation in Umlaufrichtung hintereinander entlang der Umlaufbahn der Formzapfen angeordnet sind. Zweckmäßig sind die Formzapfen an Konsolen befestigt, die an den Riemen angeschlossen und entlang der Umlaufbahn an einer Trägerplatte geführt sind.The object of the invention and solution to this problem is a device for folding flat strips of material, in particular blanks from paper or cardboard, with
  • at least one endless belt,
  • molded pins connected to the belt,
  • a folding station with machine-fixed folding tools arranged along the orbit of the shaped pins,
  • a device for positioning strips of material in the orbit of the mold pins transverse to their direction of movement and
  • a stripping station with a device for stripping off the material strips folded over on the shaped pins,
wherein the belt rotates continuously and the device for positioning the material strips, the folding station and the stripping station are arranged one behind the other in the circumferential direction along the orbit of the mold pins. The shaped pins are expediently fastened to brackets which are connected to the belt and are guided along the orbit on a carrier plate.

Die erfindungsgemäße Vorrichtung arbeitet kontinuierlich. Dabei sind üblicherweise an den Zahnriemen mehrere Stempel angeschlossen. Dies ermöglicht es, die Bearbeitungsschritte - Positionieren eines ebenen Materialstreifens, Einfalten eines Materialstreifens, Abstreifen des Materialstreifens nach erfolgter Faltung - in räumlich getrennten Stationen zeitlich synchron durchzuführen. Während ein Materialstreifen in der Umlaufbahn der Formzapfen positioniert wird, können andere, vorher zugeführte Materialstreifen bereits in der Faltstation geformt sowie in der Abstreifstation aus der Vorrichtung entnommen werden. Da Bearbeitungsschritte zeitgleich durchgeführt werden können, ermöglicht die erfindungsgemäße Lehre eine hohe Durchsatzleistung der Vorrichtung.The device according to the invention works continuously. Several stamps are usually connected to the toothed belt. This makes it possible to carry out the processing steps - positioning a flat strip of material, folding in a strip of material, stripping off the strip of material after folding - in synchronized times in spatially separate stations. While a strip of material is positioned in the orbit of the molding pins, other strips of material that have been fed in beforehand can already be formed in the folding station and removed from the device in the stripping station. Since processing steps can be carried out at the same time, the teaching according to the invention enables a high throughput of the device.

Die Faltwerkzeuge sowie die Einrichtung zur Positionierung der Materialstreifen sind in an sich bekannter Weise ausführbar. Als Faltwerkzeuge eignen sich Gleitleisten, deren Abstand vorzugsweise einstell- und veränderbar ist. Als Einrichtung zur Positionierung der Materialstreifen eignen sich beispielsweise im Abstand angeordnete Klemmbänder, welche die Materialstreifen an gegenüberliegenden Randabschnitten fassen. Eine konstruktiv bevorzugte Ausführung der Abstreifeinrichtung sieht vor, daß an den Konsolen jeweils ein Stößel mit endseitigem Abstreiferelement angeordnet ist und der Stößel durch eine Kulissensteuerung in der Abstreifstation betätigbar ist. Der Verstellhub des Abstreifelementes sowie die Stellgeschwindigkeit des Stößels sind durch die Kulissensteuerung veränderbar.The folding tools and the device for positioning the material strips can be carried out in a manner known per se. Slide strips are suitable as folding tools, the spacing of which is preferably adjustable and changeable. Suitable as a device for positioning the material strips there are, for example, spaced-apart clamping bands which grip the strips of material at opposite edge sections. A structurally preferred embodiment of the stripping device provides that a plunger with an end-side stripper element is arranged on the brackets and the plunger can be actuated by a link control in the stripping station. The adjustment stroke of the scraper element and the actuating speed of the ram can be changed by the link control.

In weiterer Ausgestaltung lehrt die Erfindung, daß zwischen der Faltstation und der Abstreifstation eine Bearbeitungsstation mit beweglichen Faltwerkzeugen angeordnet ist. Eine vorteilhafte Ausgestaltung ist dadurch gekennzeichnet, daß die Bearbeitungsstation ein mit dem Antrieb des Riemens synchron angetriebenes Umlegerad mit mindestens einem Umlegefinger aufweist, durch dessen Bewegung ein überstehendes Ende des Materialstreifens an die kontinuierlich fortbewegten Formzapfen anlegbar ist. Bei dieser Ausführung können zunächst C-förmig an den Formzapfen anliegende Material-streifen ringförmig geschlossen werden. Um zu verhindern, daß die ringförmig geschlossenen Materialstreifen auf dem weiteren Transportweg wieder aufspringen, lehrt die Erfindung, daß an die Konsolen Haltefinger schwenkbeweglich angeschlossen sind, die durch eine Kulissenführung in Umlaufrichtung in der Bearbeitungsstation schließen und hinter der Abstreifstation öffnen.In a further embodiment, the invention teaches that a processing station with movable folding tools is arranged between the folding station and the stripping station. An advantageous embodiment is characterized in that the processing station has a folding wheel which is driven synchronously with the drive of the belt and has at least one folding finger, by the movement of which a projecting end of the strip of material can be placed against the continuously moving shaped pin. In this embodiment, strips of material lying against the shaped pins can first be closed in a ring. In order to prevent the annularly closed strips of material from springing open again on the further transport route, the invention teaches that holding fingers are pivotally connected to the brackets, which close by means of a link guide in the circumferential direction in the processing station and open behind the stripping station.

Die erfindungsgemäße Vorrichtung eignet sich zum Aufrichten von Faltschachteln aus Kartonzuschnitten. Gegenstand der Erfindung ist daher auch die Verwendung der beschriebenen Vorrichtung zur Herstellung von Faltschachteln, wobei gerillte, gestanzte, auf Maß abgelängte sowie beleimte Kartonstreifen in der Umlaufbahn der Formzapfen quer zu deren Bewegungsrichtung positioniert, von einem umlaufenden Formzapfen erfaßt, während des Umlaufes in der Faltstation zu einer Faltschachtel aufgerichtet sowie in der Abstreifstation an eine Transporteinrichtung übergeben werden.The device according to the invention is suitable for erecting folding boxes made of cardboard blanks. Subject of The invention is therefore also the use of the device described for the production of folding boxes, with grooved, punched, cut to length and glued cardboard strips positioned in the orbit of the mold pins transversely to their direction of movement, captured by a rotating mold pin, during the circulation in the folding station to one Folding box erected and handed over to a transport device in the stripping station.

Die erfindungsgemäße Vorrichtung ist ferner einsetzbar, um Beipackdrucksachen aus einlagigen Papierstreifen oder mehrlagig gefalteten Papierstreifen ringförmig zu falten und in Verpackungen einzusetzen. Gegenstand der Erfindung ist daher auch die Verwendung der beschriebenen Vorrichtung zum Einlegen von Beipackdrucksachen in Verpackungen, wobei

  • einlagige oder mehrlagig gefaltete Beilagepapierstreifen in der Umlaufbahn der Formzapfen quer zu deren Bewegungsrichtung positioniert, von einem umlaufenden Formzapfen erfaßt und in der Faltstation C-förmig mit überstehendem Ende umgefaltet werden,

The invention therefore also relates to the use of the device described for inserting enclosed printed matter in packaging, wherein
  • single-layer or multi-layer folded insert paper strips are positioned in the orbit of the shaped pins transversely to their direction of movement, are gripped by a surrounding shaped pin and folded in a C-shape with a protruding end in the folding station,

Die in den Figuren dargestellte Vorrichtung dient zum Falten von ebenen Materialstreifen, insbesondere von Zuschnitten aus Papier oder Karton. Zum grundsätzlichen Aufbau der Vorrichtung gehören mindestens ein endlos umlaufender Riemen 1, an den Riemen 1 angeschlossene Formzapfen 2, eine Faltstation 3 mit maschinenfesten, entlang der Umlaufbahn der Formzapfen 2 angeordneten Faltwerkzeugen 4, eine Einrichtung 5 zur Positionierung von Materialstreifen 6 in der Umlaufbahn der Formzapfen 2 quer zu deren Bewegungsrichtung und eine Abstreifstation 7 mit einer Einrichtung 8 zum Abstreifen der umgefalteten Materialstreifen. Der Riemen 1 ist über ein Antriebsrad 9 sowie ein Umlenkrad 10 geführt und läuft kontinuierlich um. Die Einrichtung 5 zum Positionieren der Materialstreifen, die Faltstation 3 sowie die Abstreifstation 7 sind in Umlaufrichtung hintereinander entlang der Umlaufbahn der Formzapfen 2 angeordnet.The device shown in the figures is used to fold flat strips of material, in particular blanks made of paper or cardboard. The basic structure of the device includes at least one endlessly rotating belt 1, shaped pins 2 connected to the belt 1, a folding station 3 with machine-fixed folding tools 4 arranged along the orbit of the shaped pins 2, a device 5 for positioning material strips 6 in the orbit of the shaped pins 2 transverse to their direction of movement and a stripping station 7 with a device 8 for stripping the folded strips of material. The belt 1 is guided via a drive wheel 9 and a deflection wheel 10 and runs continuously. The device 5 for positioning the material strips, the folding station 3 and the stripping station 7 are arranged one behind the other in the circumferential direction along the orbit of the shaped pins 2.

Die Formzapfen 2 sind an Konsolen 11 befestigt, deren konstruktive Gestaltung in den Fig. 5a, 5b dargestellt ist. Die Konsolen 11 sind im Ausführungsbeispiel an zwei parallel geführte Zahnriemen 1 angeschlossen und entlang der Umlaufbahn an einer Trägerplatte 12 geführt. An den Konsolen 11 ist jeweils ein Stößel 13 mit endseitigem Abstreiferelement 14 angeordnet. Der Stößel 13 ist durch eine Kulissensteuerung in der Abstreifstation 7 betätigbar. Die Kulissensteuerung weist eine Kulisse 15 mit einem maschinenfesten Teil 16 sowie einem schwenkbeweglich verstellbaren Teil 17 auf, deren einstellbarer Abstand von einem einliegenden Federblech 18 überbrückt ist (Fig. 6). Die Kulisse 15 bildet mit dem einliegenden Federblech 18 eine geschlossene Kurvenbahn für eine an den Stößel 13 angeschlossene Kulissenrolle 19.The shaped pins 2 are fastened to brackets 11, the structural design of which is shown in FIGS. 5a, 5b. In the exemplary embodiment, the consoles 11 are connected to two toothed belts 1 guided in parallel and are guided along the orbit on a carrier plate 12. A plunger 13 with an end wiper element 14 is arranged on the brackets 11. The plunger 13 can be actuated by a link control in the stripping station 7. The link control has a link 15 with a machine-fixed part 16 and a pivotably adjustable part 17, the adjustable distance of which is bridged by an inserted spring plate 18 (FIG. 6). The backdrop 15 forms with the inserted spring plate 18 a closed cam track for a link roller 19 connected to the tappet 13.

Insbesondere einer vergleichenden Betrachtung der Fig. 1 und 2 entnimmt man, daß zwischen der Faltstation 3 und der Abstreifstation 7 eine Bearbeitungsstation 20 mit beweglichen Faltwerkzeugen angeordnet ist. Die Bearbeitungsstation 20 weist ein mit dem Antrieb des Riemens synchron angetriebenes Umlegerad 21 mit mindestens einem Umlegefinger 22 auf, durch dessen Bewegung ein überstehendes Ende der Materialstreifen an die kontinuierlich fortbewegten Formzapfen 2 anlegbar ist. Das Umlegerad 21 ist im Ausführungsbeispiel unter Zwischenschaltung eines Kegelradgetriebes 23 an die Antriebsvorrichtung des Antriebsrades 9 angeschlossen, so daß die Bewegungen der Zahnriemen 1 mit angeschlossenen Formzapfen 2 sowie des Umlegerades 21 synchron erfolgen. Der Figur 7 entnimmt man, daß das Kegelradgetriebe 23 durch Riemen einerseits mit der Antriebsachse 24 der Antriebsvorrichtung und andererseits mit dem Umlegerad 21 verbunden ist.In particular, a comparative examination of FIGS. 1 and 2 reveals that a processing station 20 with movable folding tools is arranged between the folding station 3 and the stripping station 7. The processing station 20 has a folding wheel 21 which is driven synchronously with the drive of the belt and has at least one folding finger 22, by means of the movement of which a protruding end of the material strips can be applied to the continuously moving mold pin 2. The folding wheel 21 is connected in the exemplary embodiment with the interposition of a bevel gear 23 to the drive device of the drive wheel 9, so that the movements of the toothed belt 1 with connected shaped pin 2 and the folding wheel 21 take place synchronously. It can be seen from FIG. 7 that the bevel gear transmission 23 is connected by belts on the one hand to the drive axle 24 of the drive device and on the other hand to the transfer wheel 21.

Insbesondere den Fig. 1 und 5a entnimmt man, daß an die Konsolen 11 Haltefinger 25 schwenkbeweglich angeschlossen sind, die durch eine Kulissenführung in Umlaufrichtung in der Bearbeitungsstation 20 schließen und hinter der Abstreifstation 7 öffnen. Die Haltefinger 25 fixieren das in der Bearbeitungsstation an die Formzapfen 2 angelegte rückwärtige Ende der Materialstreifen.1 and 5a in particular that it can be seen that holding fingers 25 are pivotally connected to the brackets 11, which close by a slide guide in the circumferential direction in the processing station 20 and open behind the stripping station 7. The holding fingers 25 fix the rear end of the material strips, which is placed on the form pins 2 in the processing station.

Die maschinenfesten Faltwerkzeuge 4 sind in an sich bekannter Weise als Faltschienen ausgeführt, deren Abstand durch eine Spindeleinrichtung 26 eingestellt und verändert werden kann. Die Fig. 8a und 8b zeigen die Faltwerkzeuge 4 mit der Spindeleinrichtung 26 in einer Stirnansicht sowie in der Draufsicht.The machine-fixed folding tools 4 are designed in a manner known per se as folding rails, the spacing of which can be set and changed by a spindle device 26. 8a and 8b show the folding tools 4 with the spindle device 26 in an end view and in a top view.

Die Fig. 3 und 4 zeigen die Anordnung der vorstehend erläuterten Baugruppen in der Vorrichtung. Der Aufbau der Vorrichtung ist unter Berücksichtigung der vorangehenden Erläutertungen aus sich heraus verständlich.3 and 4 show the arrangement of the assemblies explained above in the device. The structure of the device is self-explanatory taking into account the above explanations.

Die beschriebene Vorrichtung ermöglicht das Einlegen von Beipackzetteln in Verpackungen. Zuvor bedruckte und mehrlagig gefaltete Beilagepapierstreifen 6 werden zunächst in der Umlaufbahn der Formzapfen 2 quer zu deren Bewegungsrichtung positioniert. Sie werden von einem umlaufenden Formzapfen erfaßt und in der Faltstation 3 C-förmig mit überstehendem Ende umgefaltet. Das überstehende Ende der C-förmig eingefalteten Beilagepapierstreifen wird in der auf dem weiteren Umlaufweg angeordneten Bearbeitungsstation 20 mittels der beweglichen Faltwerkzeuge 20, 21 an die Formzapfen 2 angelegt und fixiert. Schließlich werden die ringförmig geschlossenen Beilagepapierstreifen in der Abstreifstation 7 von den Formzapfen 2 in Verpackungen 27, die unterhalb der umlaufenden Formzapfen 2 synchron zu diesen bewegt werden, hinein abgestreift.The device described enables the insertion of instruction leaflets in packaging.
