Abstract

For the production of paper cushion materials, to absorb shocks in packaging, a paper web (2) is distorted by a corrugating station (3) and picked up by transport rollers (6,7) at a transport station (5) to be forced into a stuffing channel. In the stuffing channel, the corrugated paper material (4) is forced against a limit stop (10) for compression and crushing. The resulting paper cushion material (9) is taken out of the channel to be cut into convenient portions (13). The corrugated paper (4) is further distorted into zigzags by the transport rollers (5).

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a method and a device according to the preamble of Claim 1.

Das Herstellen von Papierpolstern für die verschiedensten Anwendungsarten von stoßdämpfenden Verpackungen erfolgt in der Regel auf Großmaschinenanlagen. Dies hat den Vorteil der Massenproduktion, gleichzeitig aber auch den Nachteil, dass der Benutzer derartiger Papierpolster gezwungen ist, die Abmessungen der Polster nicht selbst bestimmen zu können, sondern die von den Großherstellern vorgegebenen Abmessungen einsetzen zu müssen, aber auch, dass der Benutzer aus Kostengründen größere Bestellungen aufgeben muß und damit nicht in der Lage ist, derartige Polster nicht bedarfsgerecht zur Verfügung zu haben.The manufacture of paper pads for a wide variety of applications shock-absorbing packaging is usually carried out on large machine systems. This has the advantage of mass production, but at the same time also the disadvantage that the Users of such paper pads are forced to change the dimensions of the pads to be able to determine themselves, but rather the ones specified by the major manufacturers Having to use dimensions, but also that the user for cost reasons must place larger orders and is therefore unable to use such upholstery not available as needed.

Aufgabe der Erfindung ist, ein Verfahren zu entwickeln, das den Benutzer bzw. Verbraucher in die Lage versetzt, an Ort und Stelle seine eigenen Papierpolster herstellen zu können, und eine Vorrichtung zu schaffen, die einfach und kostengünstig in der Herstellung und in der Bedienung ist, und die ermöglicht, beliebige Polster unterschiedlicher Abmessungen auch in Kleinserien für den eigenen Bedarf mit geringem Aufwand und niedrigen Kosten herstellen zu können.The object of the invention is to develop a method that the user or Consumers are able to put their own paper pads in place to be able to manufacture, and to create a device that is simple and inexpensive is in the manufacture and in the operation, and which enables any upholstery different dimensions also in small series for your own needs to be able to produce with little effort and low costs.

Gemäß der Erfindung wird dies mit den Merkmalen des Kennzeichens des Anspruches 1 bzw. Anspruches 4 sowie den sich daran anschließenden Unteransprüchen gelöst.According to the invention, this is with the features of the characterizing part of the claim 1 or claim 4 and the subsequent subclaims.

Mit dem erfindungsgemäßen Vorschlag wird erreicht, dass ein Verbraucher bzw. Benutzer der Polster für Verpackungszwecke derartige Papierpolster in der gewünschten Stückzahl und mit den gewünschten Abmessungen jeweils bedarfsgerecht selbst herstellen kann, so dass damit über den jeweiligen Bedarf hinausgehende Bestellungen vermieden werden können, eine entsprechende Vorratshaltung entfällt, eine Anpassung an den jeweiligen Bedarf in Hinblick auf die Abmessungen der Polster sichergestellt ist, usw.The proposal according to the invention ensures that a consumer or Users of the pads for packaging such paper pads in the desired number and with the desired dimensions each can produce according to need, so that it is above the respective need further orders can be avoided, a corresponding There is no need to keep stocks, an adjustment to the respective needs with regard to the Dimensions of the upholstery is ensured, etc.

Der Hersteller bzw. Verwender derartiger Papierpolster ist somit in der Lage, die seinem Bedarf entsprechenden Polster jeweils selbst herzustellen, indem er die die Polsterbreite festlegenden Papierrollen entsprechend auf die Maschine aufsteckt und die Papierbahn durch die Maschine laufen läßt sowie am ausgangsseitigen Maschinenende die durchtrennten Polstereinheiten abnimmt.The manufacturer or user of such paper pads is thus able to to manufacture upholstery according to his needs by making the Paper rolls that define the cushion width are placed on the machine accordingly lets the paper web run through the machine and on the output side Machine cut the severed upholstery units.

Der konstruktive Aufbau der Maschine ist unkompliziert. Die zu verformende Papierbahn wird von einer Papierrolle abgezogen und durch eine Vorform-Wellvorrichtung geführt, in der die Papierbahn vorgewellt bzw. vordeformiert wird. Diese so deformierte Papierbahn wird durch eine Transportwalzenanordnung geführt, in der die Deformation so vorgenommen wird, dass im Anschluß daran in einem Staukanal die verformte Bahn durch Stauwirkung geknittert wird und damit ein Papierpolster bzw. ein Knitter-Pack-Polster entsteht, das am rückseitigen Ende des Staukanals abgegeben und in einer Schneidvorrichtung, z.B. einer Schere, in die entsprechenden gewünschten Abschnittlängen geteilt wird. Durch die Vorverformung erhält die Papierbahn definierte Verformungsstellen, die bei fortschreitender Verarbeitung der Papierbahn die Knickstellen bilden, so dass damit die fertigen Papierpolster definierte Knitterverformungen aufweisen, die ein flexibles Verpackungspolster ergeben, das eine hohe Rückstellkraft besitzt und damit den an ein modernes Verpackungsmaterial gestellten Anforderungen entspricht.The construction of the machine is straightforward. The one to be deformed Paper web is drawn off a roll of paper and through a preform corrugator out in which the paper web is pre-corrugated or pre-deformed. This so deformed paper web is passed through a transport roller arrangement, in which the deformation is carried out in such a way that in a Congestion channel the deformed web is wrinkled by congestion and thus one Paper cushion or a crease-pack cushion is created that at the back end of the Discharge channel discharged and in a cutting device, e.g. scissors into which corresponding desired section lengths is divided. By pre-deformation the paper web receives defined deformation points, which with increasing Processing the paper web form the kinks, so that the finished Paper pads have defined crease deformations that are flexible Packaging pad result that has a high restoring force and thus the on modern packaging material meets the requirements.

Von einer Papierrolle 1 wird eine Papierbahn 2 abgezogen. Die Papierbahn ist beispielsweise ein einlagiges Natron-Kraftpapier mit einem Flächengewicht von 50 - 120 g/m2. Die Rollenbreite kann zwischen 40 und 100 cm betragen. Die Rollenbahn 2 wird durch eine Vorform-Wellblechvorrichtung 3 geführt, die aus zwei kongruent ausgebildeten, übereinander angeordneten und sich über die gesamte Breite der Vorrichtung erstreckenden Wellblechen 3A und 3B besteht, zwischen denen die Papierbahn hindurchgeführt wird. Die Wellbleche 3A und 3B sind in einem rahmenartigen Gestell 18 der Gesamtvorrichtung festgelegt und deformieren die Papierbahn 2 mit fortschreitendem Einlauf in die beiden zueinander geneigten Wellbleche, so dass die Papierbahn 4 in wellenförmiger bzw. angenähert zick-zack-förmiger Gestalt aus der Wellblech-anordnung 3 austritt und in die TransportWalzenanordnung 5 eintritt, die aus den Transportwalzen 6 und 7 besteht.A paper web 2 is drawn off from a paper roll 1. The paper web is, for example, a single-layer sodium kraft paper with a weight per unit area of 50-120 g / m 2 . The roll width can be between 40 and 100 cm. The roller conveyor 2 is guided through a preform corrugated sheet device 3, which consists of two congruently designed corrugated sheets 3A and 3B which are arranged one above the other and extend over the entire width of the device and between which the paper web is passed. The corrugated sheets 3A and 3B are fixed in a frame-like frame 18 of the overall device and deform the paper web 2 as it progresses into the two mutually inclined corrugated sheets, so that the paper web 4 is in a corrugated or approximately zigzag shape from the corrugated sheet arrangement 3 exits and enters the transport roller assembly 5, which consists of the transport rollers 6 and 7.

Das im Staukanal gebildete Papierpolster 9 in Form eines Knitter-Pack-Polsters wird am Staukanalende durch eine Klappe 10 gestaut, die entgegen dem Druck einer Feder 11 die Papierbahn solange anhält, bis der Knittervorgang im Staukanal in ausreichendem Maße durchgeführt worden ist und der Druck der nachlaufenden Papierbahn die Kraft der Feder 11 überwindet. Das Papierpolster 9 läuft dann nach Überwindung der Federkraft aus dem Staukanal aus und wird in einer Schneidvorrichtung 12 bzw. einer Schere in entsprechende Abschnitte geschnitten, so dass die jeweiligen Polstereinheiten 13 fertig geformt sind. The surface of the two transport rollers 6 and 7 is designed so that the two Rolls together form a zigzag-shaped nip surface that the Paper web 4 receives and deforms, so that the leaving the transport rollers Paper web that runs into a stowage channel 8, a zigzag-shaped over the width of the web Has deformation. The paper cushion 9 formed in the storage channel in the form of a Knitter-Pack-Pads is stowed at the end of the stagnation channel through a flap 10 which against the pressure of a spring 11, the paper web stops until the Sufficient wrinkling in the stagnation channel has been carried out and the Pressure of the trailing paper web overcomes the force of the spring 11. The Paper cushion 9 then runs out of the stowage channel after the spring force has been overcome and is cut into corresponding in a cutting device 12 or scissors Cut sections so that the respective cushion units 13 are finished.

Die Transportwalzen 6 und 7 mit zieharmonikaartiger Oberfläche 14, 15 bilden zwischen sich einen geringen, zick-zack-förmigen Spalt 16 aus, den die Papierbahn 4 durchläuft und in welchem die Papierbahn die Deformation erfährt, die für die Knitterpolster erwünscht ist. Die Trommelwalze 6 ist über eine umlaufende Achse 17, die Trommelwalze 17 über die Achse 18 an den Seitenwänden des Rahmengestells 19 gelagert.
