Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung von polsterartigen Verpackungsmaterial gemäss dem Oberbegriff des Anspruches 1 und eine Maschine mit einer derartigen Vorrichtung.The invention relates to a device for production of cushion-like packaging material according to Preamble of claim 1 and a machine with one such device.

Die zum Einsatz kommenden Vorrichtungen zum Herstellen von polsterartigen Verpackungsmaterial aus einem mindestens zwei Lagen aufweisenden, bahnförmigen Vorratsmaterial, bestehen im wesentlichen aus einem Zuführschacht, welcher die Seitenränder des Vorratsmaterials in eine im wesentlichen gerollte Form verformt und aus einer Einrichtung, um das verformte Vorratsmaterial im mittleren Bereich in dessen Längserstreckung durch Prägen zu verbinden. Hierzu sind gegeneinander vorgespannte Zahnräder oder Kettenräder mit Prägeabschnitten vorgesehen, die miteinander kämmen und den Verbindungsbereich bilden. Das verformte Vorratsmaterial durchläuft diesen Bereich, wobei davon auszugehen ist, dass die Lagen im zentralen Bereich des verformten Vorratsmaterials ungleichmässig anliegen und die Tiefe der Prägungen von der Vorspannung der Zahnräder abhängig ist, so dass die Lagen willkürlich geprägt und/oder gelocht werden. Daraus folgt, dass freiliegende Verbindungsstellen mit unterschiedlicher Güte erzeugt werden, was ein Nachteil ist. The manufacturing devices used of cushion-like packaging material from one at least two layers of sheet-like Stock material consist essentially of one Feed chute, which the side edges of the Stock material in a substantially rolled shape deformed and from a device to the deformed Stock material in the middle area in the To connect longitudinal extension by embossing. For this are gears or sprockets preloaded against each other Embossed sections are provided which comb and form the connection area. That deformed Stock material passes through this area, of which it can be assumed that the locations in the central area of the deformed stock material lie unevenly and the depth of the embossments from the preload of the gears is dependent, so that the layers are shaped arbitrarily and / or punched. It follows that exposed Joints with different quality are created become, which is a disadvantage.

Ferner kommen Vorrichtungen zum Einsatz, welche die Papierlagen mittels Perforation verbinden. Derartige Vorrichtungen weisen den Nachteil aus, dass durch die Perforierung erhebliche Mengen an Papierstaub erzeugt werden, welche die Arbeitsbedingungen für das Personal bedeuten beeinträchtigen und durch die erforderliche Reinigung einen grösseren Aufwand zur Folge haben.Devices are also used which the Connect layers of paper using perforation. such Devices have the disadvantage that Perforation creates significant amounts of paper dust which are the working conditions for the staff mean affect and by the required Cleaning will result in a greater effort.

Derartige Einrichtungen sind Bestandteil von Maschinen zur Herstellung von polsterartigen Verpackungsmaterial, das als fortlaufender Strang oder in vorbestimmten Längen hergestellt wird. Um Verpackungsmaterial in vorbestimmten Längen herzustellen, wird eine Schneidvorrichtung vorgesehen. Die Maschine enthält einen Antriebsmotor für die Vorrichtung und einen Antriebsmotor für die Schneidvorrichtung, welche die Fördergeschwindigkeit bzw. die Schnittgeschwindigkeit bestimmen. Als nachteilig erweist sich der grössere Aufwand und dass insbesondere der Schneidvorgang mit einer gleichförmigen Bewegung durchgeführt wird. Die Förderung und das Schneiden werden deshalb getrennt angesteuert, derart, dass die Förderung unterbrochen und anschliessend geschnitten wird, Hierbei wird das bewegliche Messer vor und zurück bewegt. Dieser Unterbruch schränkt die Produktionsleistung der Maschine nachhaltig ein.Such devices are part of machines for the production of cushion-like packaging material, that as a continuous strand or in predetermined lengths will be produced. To packaging material in predetermined Making lengths becomes a cutter intended. The machine contains a drive motor for the device and a drive motor for the Cutting device, which the conveying speed or determine the cutting speed. As a disadvantage it proves the greater effort and that in particular the cutting process with a uniform movement is carried out. The promotion and cutting will be therefore separately controlled, such that the promotion interrupted and then cut, Here the movable knife is moved back and forth. This Interruption limits the machine's production output sustainable one.

Es wird auf die Fig.1 und 2 Bezug genommen. Die Vorrichtung enthält einen Schacht 1 zum Zuführen der zu verbindenden Papierlagen, zwei Kettenräder 2 mit einer vorbestimmten Zahnteilung, die hintereinander auf einer Antriebsachse 3 befestigt sind und ein Gegenrad 4. Der Schacht 1 hat einen rechteckigen Querschnitt und in den Breitseiten jeweils einen Ausschnitt 5,6. Wie die Fig.2 zeigt ist das Gegenrad 4 mit einer Mehrzahl von Stiften 9 versehen, die in einer der Zahnteilung der Kettenräder 2 entsprechenden Teilung angeordnet sind. Am Umfang des Gegenrades 4 sind im mittleren Bereich ein erster ringartiger Ansatz 7 und in den Randbereichen jeweils zweite Ansätze 8 ausgebildet. Die Stifte 9 sind in den Ansätzen 7 und 8 angeordnet, wobei der Durchmesser des Umkreises der Stifte kleiner ist als der Durchmesser des Umfangs der Ansätze 7 und 8, so dass die Ansätze Stützelemente für die Papierlagen bilden. Das Gegenrad 4 ist frei drehbar auf einer Achse 14 einer Lagereinheit 10 gelagert. Die Lagereinheit 10 enthält eine ortsfeste Grundplatte 11, eine bewegliche Halteplatte 12, die über Tellerfedern 13 auf der Grundplatte abgestützt ist und zwei Lagerböcke für das Gegenrad 4, die auf der Halteplatte 12 befestigt sind.Reference is made to FIGS. 1 and 2. The Device contains a shaft 1 for feeding the connecting layers of paper, two sprockets 2 with one predetermined tooth pitch, one after the other on a Drive shaft 3 are attached and a counter wheel 4. The Shaft 1 has a rectangular cross section and in the Broad sides each a section 5.6. As the Fig.2 shows the counter wheel 4 with a plurality of pins 9 provided in one of the tooth pitch of the chain wheels 2 corresponding division are arranged. At the extent of Counter wheel 4 are a first in the central area ring-like approach 7 and in the edge areas each second approaches 8 formed. The pins 9 are in the Approaches 7 and 8 arranged, the diameter of the The circumference of the pins is smaller than the diameter of the Scope of approaches 7 and 8, so the approaches Form support elements for the paper layers. The counter wheel 4 is freely rotatable on an axis 14 of a bearing unit 10 stored. The storage unit 10 contains a stationary one Base plate 11, a movable holding plate 12, the Disc springs 13 is supported on the base plate and two bearing blocks for the counter wheel 4, which on the Holding plate 12 are attached.

Aus der Fig.1 ist die Zuordnung der Kettenräder 2 und des Gegenrades 4 untereinander und zum Zuführschacht 1 ersichtlich. In Abkehr von den bekannten Vorrichtungen ist bei der hier in Rede stehenden Vorrichtung die Ebene 15, welche durch die Drehachsen der Kettenräder und dem Gegenrad verläuft, zu der Laufebene des verformten Vorratsmaterial, welche vom Zuführschacht bestimmt wird geneigt, angeordnet. Dadurch wird in besonders vorteilhafter Weise einerseits eine bessere Verbindung der Lagen untereinander und andererseits der Durchlauf der Lagen und insbesondere der Auslauf des Verpackungsmaterials verbessert. Ferner werden durch diese Zuordnung die Lagen zuerst von den Kettenzähnen erfasst und gegen die Mantelfläche der Stützelemente 7 und 8 des Gegenrades 4 gedrückt, wodurch der Verbindungsbereich der Lagen festgelegt wird. Im eigentlichen Verbindungsbereich, d.h. in den Abschnitten zwischen den Stützelementen 7 und 8 erfolgt die Verbindung durch Pressen der Lagen.From Figure 1 is the assignment of the sprockets 2 and Counter wheel 4 with each other and to the feed shaft 1 seen. In a departure from the known devices is the level in the device in question 15, which by the axes of rotation of the sprockets and the Counter wheel runs to the running plane of the deformed Storage material, which is determined by the feed shaft inclined, arranged. This will in particular advantageously a better connection on the one hand the layers with each other and on the other hand the run the locations and in particular the outlet of the Packaging material improved. Furthermore, by this mapping the layers first from the chain teeth detected and against the lateral surface of the support elements 7 and 8 of the counter wheel 4 pressed, whereby the Connection area of the layers is determined. in the actual connection area, i.e. in the sections between the support elements 7 and 8 Connection by pressing the layers.

Die den Figuren 3 und 4 dargestellte Vorrichtung unterscheidet sich von der vorstehend beschriebenen Vorrichtung nur durch das Gegenrad 21, so dass die nachfolgende Beschreibung sich lediglich auf die Ausbildung desselben beschränkt. Das Gegenrad 21 weist an der Peripherie zwei Zahnreihen, die parallel angeordnet sind. Jede Zahnreihe weist eine Mehrzahl von Zähnen 22 auf, die mit den Kettenrädern 2 kämmen. Die Zähne haben einen runden Scheitelabschnitt 23 und zur Zahnwurzel hin konvergierende Zahnflanken. Anstelle der Ansätze bei dem Gegenrad 4 gemäss Fig. 1 und 2 sind als Stützelemente scheibenförmige Ringe 26 und 25 zwischen den Zahnreihen bzw. an den Stirnseiten des Gegenrades angeordnet und mit geeigneten Mitteln befestigt.The device shown in Figures 3 and 4 differs from that described above Device only through the counter gear 21 so that the the following description only refers to the Limited training. The counter gear 21 instructs the periphery two rows of teeth arranged in parallel are. Each row of teeth has a plurality of teeth 22 that mesh with the sprockets 2. Have teeth a round apex section 23 and towards the tooth root converging tooth flanks. Instead of the approaches at the Counter wheel 4 according to FIGS. 1 and 2 are used as support elements disc-shaped rings 26 and 25 between the rows of teeth or arranged on the end faces of the counter wheel and with appropriate means attached.

Es wird auf die Fig.5 und 6 Bezug genommen. Wie die Fig.5 zeigt, ist die Schneidvorrichtung mittels einer Platte 31 mit dem Zuführschacht 1 der Vorrichtung so verbunden, dass der Zuführschacht bündig mit der Oberseite der Platte ist. Die Schneidvorrichtung enthält ein feststehendes Messer 32 und ein bewegliches Messer 33. Auf der Platte 31 sind Führungsleisten 34 für das bewegliche Messer 33 mit geeigneten Mitteln 35 befestigt. Das feststehende Messer 32 ist an den Führungsleisten 34 so befestigt, dass die Schneidkante 36 bündig mit der die Öffnung des Zuführschachtes begrenzenden Kante ist. Das bewegliche Messer 33 besteht aus zwei Teilmessern 37,38 und einer Anschlussplatte 39, an welcher die Teilmesser befestigt sind und die ein Langloch aufweist, um das bewegliche Messer mit einer später beschriebenen Hebelanordnung zu verbinden. Die Teilmesser 37,38 haben geneigte Schneidkanten und sind an der Anschlussplatte 39 so befestigt, dass einerseits deren Schneidkanten zueinander versetzt sind und gemeinsam eine bezüglich der Öffnung des Zuführschachtes divergierende Schneidkante bilden. Mit dieser Anordnung wird das Schneiden des Verpackungsmaterials in vorteilhafter Weise verbessert.5 and 6 are referred to. Like Fig.5 shows, the cutting device is by means of a plate 31 connected to the feed shaft 1 of the device in such a way that the feed chute is flush with the top of the Plate is. The cutter includes a fixed knife 32 and a movable knife 33. On the plate 31 are guide rails 34 for that movable knife 33 attached by suitable means 35. The fixed knife 32 is on the guide strips 34 attached so that the cutting edge 36 is flush with the The opening of the feed chute is the edge. The Movable knife 33 consists of two partial knives 37, 38 and a connecting plate 39 on which the dividing knife are attached and which has an elongated hole to the movable knife with a later described Connect lever arrangement. The dividing knives have 37.38 inclined cutting edges and are on the connecting plate 39 attached so that on the one hand the cutting edges are offset from one another and together one with respect to the Opening of the feed chute diverging cutting edge form. With this arrangement, the cutting of the Packaging material improved in an advantageous manner.

Wie eingangs erwähnt, ist die Schneidvorrichtung mit der Antriebsvorrichtung 40 verbunden. Hierzu sind eine Kupplung 41 und eine Hebelanordnung 42 vorgesehen. Die Kupplung ist eine herkömmliche Magnetkupplung, mit welcher die Verbindung der Hebelanordnung mit der gemeinsamen Antriebswelle erfolgt. Die Hebelanordnung 42 umfasst einen einarmigen Hebel 45 der mit dem beweglichen Kupplungsteil verbunden ist, einen zweiarmigen Hebel 46, der mit dem beweglichen Messer 33 verbunden ist und eine Verbindungsstange 47 mit zwei Gelenkköpfen 48, die mit dem einarmigen bzw. mit dem zweiarmigen Hebel verbunden sind. Es sind zwei Zugfedern 49 vorgesehen, die einerseits am einarmigen Hebel und andererseits am nicht dargestellten Gestell eingehängt sind, um den ersten Hebel in einer Ruhestellung zu halten. Der zweiarmige Hebel 46 ist an einen Bolzen 43 gelagert, welcher auf der Platte 31 angeordnet ist. Der zweiarmige Hebel 46 ist mittels einer Schraube 56 mit der Verbindungsstange 47 und über einen Stift 44, der in das Langloch der Anschlussplatte 39 eingreift mit dem beweglichen Messer 33 verbunden.As mentioned at the beginning, the cutting device is connected to the drive device 40. For this purpose, a clutch 41 and a lever arrangement 42 are provided. The clutch is a conventional magnetic clutch, with which the lever arrangement is connected to the common drive shaft. The lever arrangement 42 comprises a one-armed lever 45 which is connected to the movable coupling part, a two-armed lever 46 which is connected to the movable knife 33 and a connecting rod 47 with two joint heads 48 which are connected to the one-armed or to the two-armed lever , Two tension springs 49 are provided, which are hooked in on the one hand to the one-armed lever and on the other hand to the frame (not shown) in order to hold the first lever in a rest position. The two-armed lever 46 is mounted on a bolt 43 which is arranged on the plate 31. The two-armed lever 46 is connected to the movable knife 33 by means of a screw 56 with the connecting rod 47 and via a pin 44 which engages in the elongated hole of the connecting plate 39.

Die Hebelanordnung 42 ist dazu bestimmt, die Drehbewegung der Antriebswelle in eine translatorische Messerbewegung umzuwandeln und die Messerbewegung so zu beschleunigen, dass das mit einem Vorschub von über 30 Meter pro Minute der Schneidvorrichtung zugeführte Verpackungsmaterial ohne Unterbruch der Zuführung zuverlässig geschnitten wird.The lever assembly 42 is designed to rotate the drive shaft into a translatory knife movement convert and accelerate the knife movement so that with a feed rate of over 30 meters per minute packaging material fed to the cutting device Cut reliably without interrupting the feed becomes.

Es wird auf die Fig.7 und 8 Bezug genommen. Die Vorrichtung enthält einen Schacht 1 zum Zuführen der zu verbindenden Papierlagen, zwei Kettenräder 2 mit einer vorbestimmten Zahnteilung, die nebeneinander auf einer Antriebsachse 3 befestigt sind und ein Gegenrad 50. Der Schacht 1 hat einen rechteckigen Querschnitt und in den Breitseiten jeweils einen Ausschnitt 5 und 6. Wie die Fig.7 zeigt ist das Gegenrad 50 mit einer Mehrzahl von Stiften 9 versehen, deren Teilung der Zahnteilung der Kettenräder 2 entspricht. Am Umfang des Gegenrades 50 sind im mittleren Bereich ein erster ringförmiger Ansatz 51 und in den Randbereichen jeweils zweite ringförmige Ansätze 52 ausgebildet. Der erste Ansatz 51 enthält Abschnitte mit Löchern zum Befestigen der Stifte 9 und die zweiten Ansätze enthalten Abschnitte mit muldenförmigen Aussparungen zur Aufnahme der Stifte 9. Der erste Ansatz 51 hat eine Kontur mit vorspringenden Abschnitten 53 und mit zurückspringenden Abschnitten 54. Die vorspringenden Abschnitten 54 liegen auf einem Umkreis dessen Durchmesser mindestens 1 mm grösser als der Umkreis der Stifte ist. Die zurückspringenden Abschnitte 54 sind muldenförmig, wobei deren Scheitel auf dem Umkreis der Stifte 9 liegt. Die Kanten der Abschnitte, insbesondere der vorspringenden Abschnitte sind gerundet. Dies hat den Vorteil, dass ein Schneiden der durchlaufenden Papierlagen vermieden und folglich weniger Papierstaub erzeugt wird. Das Gegenrad 50 ist in zwei Lagereinheiten 10 frei drehbar gelagert, wobei nur eine Lagereinheit dargestellt ist. Jede Lagereinheit 10 enthält eine ortsfeste Grundplatte 11 und eine bewegliche Halteplatte 12, die über Tellerfedern 13 auf der Grundplatte abgestützt ist. Auf der Halteplatte 12 ist ein Stehlager für das Gegenrad 4 befestigt.Reference is made to FIGS. 7 and 8. The device contains a shaft 1 for feeding the layers of paper to be connected, two chain wheels 2 with a predetermined tooth pitch, which are fastened next to one another on a drive shaft 3, and a counter wheel 50 . The shaft 1 has a rectangular cross section and a cutout 5 and 6 in the broad sides, as shown in FIG . On the circumference of the counter wheel 50, a first annular projection 51 is formed in the central region and second annular projections 52 are formed in the edge regions. The first projection 51 contains sections with holes for fastening the pins 9 and the second approaches contain sections with trough-shaped recesses for receiving the pins 9. The first projection 51 has a contour with projecting sections 53 and with projecting sections 54. The projecting sections 54 lie in a radius whose diameter is at least 1 mm larger than the radius of the pins. The recessed sections 54 are trough-shaped, the apex of which lies on the circumference of the pins 9. The edges of the sections, in particular the projecting sections, are rounded. This has the advantage that cutting through the continuous paper layers is avoided and consequently less paper dust is generated. The counter wheel 50 is freely rotatably supported in two bearing units 10, only one bearing unit being shown. Each bearing unit 10 contains a stationary base plate 11 and a movable holding plate 12 which is supported on the base plate by means of disc springs 13. A plummer block for the counter wheel 4 is fastened on the holding plate 12.

Die in den Figuren 9 und 10 dargestellte Ausführung der Vorrichtung unterscheidet sich von der Ausführung gemäss Fig. 7 und 8 dadurch, das an beiden Seiten des Gegenrades 50 jeweils eine Stützscheibe 61 angeordnet ist, wobei die Stützscheiben den Verbindungsbereich bestimmen. Die Stützscheiben 61 haben einen Durchmesser der gleich dem Durchmesser des Umkreises der Stifte 9 ist. Es wir darauf hingewiesen, dass in Abhängigkeit der zu verformenden Papierart Stützscheiben mit einem grösseren oder kleineren Durchmesser angewendet werden, um ein Bersten der Papierlagen während der Prägung zu verhindern. Die Stützscheiben weisen eine Scheibe 62 und eine Nabe 63 auf und bestehen aus Metall oder Kunststoff. Die Stützscheiben können auch einstückig ausgebildet sein. Am Umfang sind die Stützscheiben gerundet. Die Stützscheiben sind auf der Achse des Gegenrades drehbar oder fest montiert.The embodiment of the shown in Figures 9 and 10 Device differs from the version according to 7 and 8 thereby, that on both sides of the counter wheel 50 each a support disc 61 is arranged, the Support washers determine the connection area. The Support discs 61 have a diameter equal to that Diameter of the circumference of the pins 9 is. It is on it noted that depending on the to be deformed Paper type support washers with a larger or smaller diameters can be applied to bursting to prevent the paper layers from being embossed. The Support disks have a disk 62 and a hub 63 and are made of metal or plastic. The Support disks can also be formed in one piece. At the The supporting disks are rounded in circumference.
