Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung mit Lack oder Kunststoff oder sonstigen Korrosionsschutzmitteln beschichteten Behältern, bei denen der Behältermantel aus einem rechteckigen Blechzuschnitt hergestellt wird, der entsprechend der spätern Form des Behältermantels gebogen wird und an den aneinander stoßenden Längskanten stumpf oder überlappend verschweißt oder gelötet wird und an den Behältermantel der Boden und eventuell auch der Deckel angefalzt wird und der Blechzuschnitt von einer langen, in der Regel zu einem Coil aufgewickelten Blechbahn abgeschnitten wird.The invention relates to a method and a device for the production of containers coated with lacquer or plastic or other anti-corrosion agents, in which the container jacket is produced from a rectangular sheet metal blank, which is bent according to the later shape of the container jacket and welded to the abutting longitudinal edges butt-welded or overlapping or is soldered and the bottom and possibly also the lid are folded onto the container jacket and the sheet metal blank is cut off from a long sheet metal sheet, which is generally wound into a coil.
Es ist bekannt, den Behälter zunächst aus unbeschichtetem Blech herzustellen und den fertigen Behälter anschließend durch Spritzen oder Tauchen zu beschichten.It is known to first produce the container from uncoated sheet metal and then to coat the finished container by spraying or dipping.
Die Beschichtung im fertigen Zustand des Behälters mußte bisher deshalb durchgeführt werden, weil sich beschichtetes Blech nicht Schweißen oder Löten läßt, weil die Beschichtung z. B. beim Rollnahtschweißen isolierend wirkt und den Stromdurchgang verhindert.The coating in the finished state of the container previously had to be carried out because coated sheet metal cannot be welded or soldered, because the coating z. B. has an insulating effect during roller seam welding and prevents the passage of current.
Das bisherige Verfahren hat den Nachteil, daß die Emballagen herstellende Industrie wegen der heutigen strengen Umweltbestimmungen sehr aufwendige Beschichtungseinrichtungen unterhalten muß. Die beschichteten Emballagen müssen wegen ihres großen Volumens in außerordentlich großen Trocknungsöfen getrocknet werden.The previous method has the disadvantage that the packaging industry has to maintain very complex coating facilities due to today's strict environmental regulations. Because of their large volume, the coated packaging must be dried in extraordinarily large drying ovens.
Es ist außerdem bekannt, eine Blechbahn mit einer schmaleren Beschichtungswalze, als die Breite der Blechbahn beträgt, zu beschichten, so daß die äußeren Ränder unbeschichtet bleiben. An die unbeschichteten Ränder werden später beim Zusammenschweißen des Behälters die Schweißnähte gelegt. Diese vorbeschichteten Blechbahnen haben den Nachteil, daß der Umfang der Behälter der Breite der Blechbahn entsprechen muß. Beim Wechsel auf z. B. im Durchmesser kleinere Behälter muß die Blechbahnbreite verändert werden und es muß eine schmalere Beschichtungswalze eingesetzt werden. Dies ist sehr umständlich, weil mehrere Blechbahnbreiten und Beschichtungswalzenbreiten auf Vorrat gehalten werden müssen.It is also known to coat a sheet of metal with a narrower coating roller than the width of the sheet of sheet, so that the outer edges remain uncoated. The weld seams are later placed on the uncoated edges when the container is welded together. These pre-coated sheet metal sheets have the disadvantage that the circumference of the containers must correspond to the width of the sheet metal sheet. When changing to z. B. smaller diameter containers, the sheet width must be changed and a narrower coating roller must be used. This is very cumbersome because several sheet widths and coating roller widths have to be kept in stock.
Der Erfindung liegt die Aufgabe zugrunde, aufwendige Beschichtungsanlagen bei den Emballagenherstellern einzusparen und ein Verfahren und eine Vorrichtung zu schaffen, bei dem mit einer Blechbahnbreite ohne den Wechsel von Beschichtungswalzen auch im Durchmesser kleinere Behälter hergestellt werden können.The invention has for its object to save complex coating systems at the packaging manufacturers and to create a method and an apparatus in which smaller sheet containers can be produced with a sheet width without changing coating rollers.
Diese Aufgabe wird durch das im kennzeichnenden Teil des Anspruches 1 beschriebene Verfahren und durch die im kennzeichnenden Teil der Ansprüche 4 und 5 beschriebenen Vorrichtung gelöst. Weiterbildungen des Verfahrens und der Vorrichtung sind in den Unteransprüchen 2 und 3 und 5 bis 9 beschrieben.This object is achieved by the method described in the characterizing part of claim 1 and by the device described in the characterizing part of claims 4 and 5. Further developments of the method and the device are described in subclaims 2 and 3 and 5 to 9.
Das Verfahren und die Vorrichtung sind nicht an eine einzige Fabrikationsstätte gebunden. Es kann z. B. die Beschichtung des Blechbandes beim Blechhersteller erfolgen und es kann das Blechband als beschichtetes Coil oder in Form von Blechzuschnitten dem Emballagenhersteller geliefert werden. Für die Erfindung ist lediglich entscheidend, daß bei der Beschichtung, wo immer sie auch erfolgt, entsprechende Streifen für die später zu verschweißenden Kanten freigelassen werden oder nach dem Aushärten der Beschichtung eingeschliffen werden. Beim Emballagenhersteller werden später am fertigen Behälter lediglich die fertigen Schweißnähte beschichtet, was wegen der kleinen Flächen auch mit einfachen Mitteln umweltfreundlich möglich ist.The method and the device are not tied to a single production facility. It can e.g. B. the coating of the sheet metal strip at the sheet metal manufacturer and it can be supplied to the packaging manufacturer as a coated coil or in the form of sheet metal blanks. It is only decisive for the invention that, wherever it occurs, corresponding strips are left free for the edges to be welded later, or are ground in after the coating has hardened. At the packaging manufacturer, only the finished weld seams are later coated on the finished container, which is also possible in an environmentally friendly way with simple means due to the small areas.
Ein Ausführungsbeispiel der Erfindung wird anhand der Fig. 1, 2 und 3 näher erläutert.An embodiment of the invention is explained in more detail with reference to FIGS. 1, 2 and 3.
Die Fig. 1 zeigt die Beschichtungsstation, die Fig. 2 die Schneidestation und Fig. 3 eine Draufsicht auf die beschichtete Blechbahn.1 shows the coating station, FIG. 2 shows the cutting station and FIG. 3 shows a top view of the coated sheet metal.
In der Beschichtungsstation wird das unbeschichtete Blechband 12 vom Coil 11 abgewickelt und läuft über eine Umlenkrolle 13 zu einer weiteren Umlenkrolle 14 an der die durch den hydraulischen Kolben 25 andrück- und abhebbare Beschichtungsrolle 15 angebracht ist, die mit dem Beschichtungsmittel aus der Wanne 16 durch die Rolle 17 versorgt wird. Das beschichtete Blechband 12 läuft durch den Trocknungsofen 18.In the coating station, the uncoated
Für das aus dem Trocknungsofen herauskommende Blechband gibt es zwei weitere mögliche Verarbeitungswege.There are two other possible processing methods for the sheet metal strip coming out of the drying oven.
Bei dem einen Weg wird das Blechbahnd 12 über die Umlenkrolle 19 zu einer Coilaufwickelvorrichtung geführt, wo es zum Coil 20 aufgewickelt wird. Die aufgweickelten Coils 20 werden zum Emballagenhersteller transportiert. Der Emballagenhersteller besitzt eine in Fig. 2 dargestellte Schneidstation.In one way, the
In der Schneidstation wird das Coil 20 wieder abgweickelt und durch die Schere 21 geführt und in Tafeln 22 bis 24 zerteilt. Es entspricht die Länge einer jeden Tafel dem Umfang des daraus herzustellenden Behältermantels. Beim Beschichten wurde die Beschichtungsrolle 15 durch den hydraulischen Kolben 25 kurzzeitig vom Blechband 12 abgehoben, so daß die in der Fig. 3 mit 26, 27 und 28 bezeichneten nicht beschichteten Querstreifen auf dem Blechband 12 entstehen. Die Schere 21 zerteilt das Blechband 12 im mittleren Bereich dieser Querstreifen, so daß die Tafeln 22, 23 und 24 entstehen, von denen jede den Zuschnitt für den herzustellenden Behältermantel darstellt, wobei der später zum Mantel gebogene Zuschnitt an den von der Be schichtung freien Kanten in einer parallel zur Mantelachse verlaufenden Schweißnaht verschweißt wird und die übrigen Kanten des ehemaligen Blechzuschnitts die Anschlußkanten zum Anfalzen bzw. Anbringen des Deckels oder Bodens des Behälters darstellen.In the cutting station, the
Der zweite mögliche Weg des Blechbandes 12 ist in der Fig. 1 gestrichelt angedeutet. Das Blechband 12 läuft direkt durch die Schere 21 und wird in die Tafeln 22 bis 24 zerschnitten und diese werden zu den Blechmänteln in einer nicht gezeichneten Vorrichtung weiter verarbeitet. Es können auch die Blechtafeln zum Emballagenhersteller transportiert werden, so daß die Herstellung des Behälters in einer eigenen Fabrikationsstätte erfolgt.The second possible path of the
Die unbeschichteten Querstreifen 26, 27 und 28 müssen, entsprechend dem Behälterumfang in einem genau definierten Abstand auf dem Blechband 12 erzeugt werden.The uncoated
Zu diesem Zweck ist die Umlenkrolle 13 gleichzeitig eine Meßrolle, bei der in bekannter Weise das durchgelaufene Blechband 12 bzw. die Umdrehungen in elektrische Impulse verwandelt und über die Leitung 30 zu einer Steuervorrichtung 31 gegeben werden. In dieser Steuervorrichtung 31 ist ein Wegzähler enthalten. Nachdem eine der Länge einer Tafel 22 abzüglich der Breite des Querstreifens durchgelaufene Länge des Blechbandes 12 unter der Beschichtungsrolle 15 durchgelaufen ist, wird von der Steuervorrichtung 31 über die Leitung 32 das Magnetventil 29 gesteuert, das wiederum den Kolben 25 in Abhebrichtung der Beschichtungsrolle 15 steuert. Nach dem Durchlauf der Breite eines Querstreifens 26 wird der Kolben 25 wieder in Andrückstellung gesteuert. Das Magnetventil 29 wird von der nicht gezeichneten Pumpe über die Leitung 33 und 34 mit Hydrauliköl versorgt.For this purpose, the
Die Steuervorrichtung 31 kann auch gleichzeitig eine Schere 21 zum Zerteilen des Blechbandes 12 steuern, wenn der Weg des Blechbandes 12 zwischen der Umlenkrolle 13 und der Schere 21 mit berücksichtigt wird. Die Schere 21 wurde gestrichelt gezeichnet, da sie auch an einer anderen Fabrikationsstätte aufgestellt sein kann.The
Wenn das beschichtete Blechband zu einem Coil aufgewickelt wird und zu einer speziellen Fabrikationsstätte für Emballagen transportiert wird, so wird zur Steuerung der Schere eine gesonderte Meßeinrichtung benötigt. Diese ist ebenfalls mit einem Meßrad oder Anschlag zum Abmessen der Länge einer Tafel ausgestattet. Es ist auch möglich, den unbeschichteten quer verlaufenden Streifen durch einen unterschiedlich reflektierten Lichtstrahl in seiner Länge und Breite zu ermitteln.If the coated metal strip is wound into a coil and transported to a special manufacturing facility for packaging, a separate measuring device is required to control the scissors. This is also equipped with a measuring wheel or stop for measuring the length of a board. It is also possible to determine the length and width of the uncoated, transverse strip by means of a differently reflected light beam.
Dies geschieht in der einfachsten Form mit Hilfe von Photozellen. Mit Hilfe einer Diodenzeilenkamera wird die Breite und die Lae des unbeschichteten Streifens auf 0,1 mm genau bestimmt.This is done in the simplest form with the help of photocells. With the aid of a diode line camera, the width and the length of the uncoated strip are determined with an accuracy of 0.1 mm.
Es sind verschiedene Abwandlungen der Vorrichtung zur Durchführung des Verfahrens möglich. So kann das Blechband auch durch Spritzen beschichtet werden und die nicht beschichteten Querstreifen sind durch Bekleben mit Klebeband oder durch Abdecken mit einer Schablone herstellbar. Die Behälter können von rundem oder auch eckigem Querschnitt sein.Various modifications of the device for carrying out the method are possible. The sheet metal strip can also be coated by spraying and the non-coated transverse strips can be produced by sticking with adhesive tape or by covering with a template. The containers can be of round or angular cross-section.
Die Beschichtungsrolle kann ansstelle mit einem Kolben durch z. B. einen Magneten angehoben werden. Die Beschichtungsrolle wird zur Massenreduzierung zweckmäßig innen hohl gesteltet und aus einem leichten Werkstoff hergestellt.The coating roller can instead of a piston by z. B. raised a magnet. In order to reduce the mass, the coating roll is expediently made hollow on the inside and made from a light material.
Die Formstation für die Behältermäntel und die Behälterböden und die Schweißstation sind an der rechten Seite der Fig. 1 nicht eingezeichnet, da diese von bekannter herkömmlicher Bauart sind.The forming station for the container jackets and the container bottoms and the welding station are not shown on the right side of FIG. 1, since these are of a known conventional type.
Bei einer Abwandlung der Vorrichtung wird das Blechband 12 kontinuierlich beschichtet. Zwischen dem Trocknungofen 18 und der Umlenkrolle 19 ist eine Schleifvorrichtung eingebaut, die einen Schleifstein von der Breite der unbeschichteten Querstreifen besitzt und mit der diese Querstreifen aus der Beschichtung herausschleifbar sind. Der Schleifstein wird in analoger Weise wie der hydraulische Kolben 25 von der Steuervorrichtung 31 gesteuert.When the device is modified, the
In der Fig. 1 wird mit der Beschichtungsrolle 15 nur die obere Seite des Blechbandes 12 beschichtet. Eine gleiche Abheb- und Beschichtungsvorrichtung ist auch an der Unterseite des Blechbandes 12 anbringbar. Diese untere Seite kann später die Innenseite des Behältermantels ergeben. Für diese Innenseite ist oft schon eine Beschichtung aus z. B. Wachs als Korrosionsschutz ausreichend.
