Description
Die Erfindung betrifft ein Verfahren der im Oberbegriff
des Anspruchs 1 genannten Art zum Anbringen von Henkeln
an Behälter aus Metall sowie eine Vorrichtung gemäß
Anspruch 4 zur Durchführung des Verfahrens.The invention relates to a method in the preamble
of
Durch US-PS 1,670,131 ist ein Verfahren der betreffenden Art bekannt, bei dem an einen Behälter aus Metall zunächst nach dem Buckelschweißverfahren Ohren angeschweißt werden, die jeweils ein Loch aufweisen, in die ein Haken am Ende eines bügelförmigen Henkels eingehakt wird. Die Ohren bestehen aus einem napfförmigen Grundkörper, von dessen Rändern sich ein Flansch erstreckt, aus dem rippenförmige Buckel vorstehen, während sich das Loch im Boden des Grundkörpers befindet. Zur Verbindung der Ohren mit dem Behälter aus Metall werden die Flansche der Ohren mit den Buckeln durch eine äußere Elektrode gegen die Außenwandung des Behälters gedrückt, an der von innen eine Gegenelektrode anliegt. Durch die erhöhten Übergangswiderstände im Bereich der Anlagen der Buckel erfolgt eine Widerstandsverschleißung im Bereich der Buckel. Nach der Anbringung der Ohren muß das Einhängen der Bügel mit den Haken in die Löcher der Ohren von Hand erfolgen. Die Fertigungskosten sind daher verhältnismäßig hoch.Through US-PS 1,670,131 is a method of the concerned Kind known in the first to a metal container ears welded using the hump welding process each have a hole in which a hook hooked onto the end of a bow-shaped handle. The Ears consist of a bowl-shaped body, from the edges of which extend a flange from which rib-shaped Humps protrude while the hole in the ground of the base body. To connect the ears with the flanges of the ears are attached to the metal container the humps through an outer electrode against the outer wall of the container, on the inside of a counter electrode is present. Due to the increased contact resistance Resistance wear occurs in the area of the humps in the area of the hump. After Attachment of the ears must be done by hanging the bracket with the Hooks into the holes in the ears are done by hand. The manufacturing cost are therefore relatively high.
Durch die Firmendruckschrift "Fully Automatic Ear Welding and Bailing Line Series 40" der Firma MFB Maschinenfabrik GmbH in D-38021 Braunschweig ist eine Vorrichtung zur Durchführung eines Verfahrens der zuvor genannten Art bekannt, bei dem die Henkel in der Maschine aus Drahtstücken geformt und mit ihren hakenförmigen Enden in die Löcher in den Ohren eingesetzt werden. Eine Anbringung von Henkeln aus Kunststoff ist mit dieser bekannten Vorrichtung nicht möglich.Through the company publication "Fully Automatic Ear Welding and Bailing Line Series 40 "from MFB Maschinenfabrik GmbH in D-38021 Braunschweig is a device to carry out a method of the aforementioned Kind known in which the handle in the machine formed from pieces of wire and with their hook-shaped Ends inserted into the holes in the ears become. Attaching plastic handles is not possible with this known device.
Durch die GB 2082481 A ist ein Verfahren zum Anbringen von Henkeln an Behältern aus Metall bekannt, bei der die Behälter mit Nietlöchern zur Einführung und Befestigung eines Niets versehen sind, der als Drehlager und Halterung für einen an seinen Enden mit Löchern versehenen Henkeln dient. Die Montage erfolgt in der Weise, daß jeweils zunächst ein Handgriff in eine Position gebracht wird, in der jeweils ein Loch an einem Ende eines Handgriffs mit einem Nietloch in dem Behälter fluchtet und ein Lokalisierungsstift durch beide Löcher hindurchführbar ist. Dann wird ein Niet durch jedes Paar von miteinander fluchtenden Löchern an einem Ende des Handgriffes und in dem Behälter und über den jeweiligen Lokalisierungsstift gebracht, derart, daß der Schaft des Niets innerhalb jedes Paares von Löchern sitzt. Daraufhin erfolgt die Vernietung des Nietschaftes in dem Loch in dem Behälter und die Rückziehung des Lokalisierungsstiftes. Dieses bekannte Verfahren hat den Nachteil, daß in dem Behälter Nietlöcher erforderlich sind, daß die Löcher an den Enden der Henkel zu den Nietlöchern ausgerichtet, dann die Niete in die Nietlöcher eingeführt werden müssen, ehe die Vernietung erfolgen kann. Diese Ausrichtung der verschiedenen Löcher zueinander, wozu eine Drehung des Behälters erforderlich ist, um die Nietlöcher in dem Behälter in Einführ- und Nietposition zu bringen, ist außerordentlich umständlich, abgesehen davon, daß vorher die Nietlöcher in dem Behälter angebracht werden müssen. GB 2082481 A is a method of attachment known from handles on metal containers, where the container with rivet holes for insertion and attachment of a rivet are provided as Swivel and bracket for one at its ends with Holed handles. The assembly takes place in such a way that first a handle in a position is brought in, in each case a hole at one end of a handle with a rivet hole in the container is aligned and a locating pin can be passed through both holes. Then one Rivet through each pair of aligned Holes at one end of the handle and in the container and the respective localization pen brought such that the shaft of the rivet within each pair of holes sits. Then the Riveting the rivet shaft in the hole in the container and the withdrawal of the localization pen. This known method has the disadvantage that in the container rivet holes are required that the Holes at the ends of the handles to the rivet holes aligned, then insert the rivet into the rivet holes must be done before riveting can. This alignment of the different holes to each other, which requires a rotation of the container to bring the rivet holes in the container in the insertion and riveting position is extraordinary awkward, apart from the fact that the Rivet holes need to be made in the container.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Anbringen von Henkeln an Behälter aus Metall zu schaffen, das einfach durchzuführen und für die maschinelle Anbringung von Henkeln aus Kunststoff geeignet ist. Aufgabe der Erfindung ist es auch, eine Vorrichtung zur Durchführung dieses Verfahrens zu schaffen.The invention is based on the object Process for attaching handles to containers To create metal that is easy to carry out and for the mechanical attachment of handles made of plastic suitable is. The object of the invention is also a Device for performing this method create.
Die der Erfindung zugrundeliegende Aufgabe wird
durch das im Kennzeichen des Anspruchs 1 angegebene
Verfahren gelöst. Sie wird auch durch die im Kennzeichen
des Anspruchs 4 angegebene Vorrichtung gelöst.The object underlying the invention will
by that specified in the characterizing part of
Der Erfindung liegt der Gedanke zugrunde, einen Henkel aus Kunststoff und eine einen Flansch aufweisende und als Lagerzapfen für den Henkel bestimmte Öse zunächst zusammenzuführen und dann die Öse nach dem bekannten Buckelschweißverfahren an den aus Metall bestehenden Behälter anzuschweißen. Der Schweißvorgang erfolgt also, während sich der aus Kunststoff bestehende Henkel bereits auf der Öse und somit im Schweißbereich befindet. Bei dem Schweißvorgang wird der üblicherweise aus thermoplastischem Kunststoff bestehende Henkel nicht beschädigt oder gar geschmolzen. Die an den Buckeln gebildeten Widerstandsschweißstellen führen nicht zu einer solchen Erhöhung der Temperatur der Öse, die zu einer Beeinträchtigung des Kunststoffes des Henkels führen kann. Hierzu trägt auch die Tatsache bei, daß die kalte, an der Öse während des Schweißvorganges anliegende Schweißelektrode für eine Wärmeabfuhr von der Öse gerade in dem Bereich beiträgt, in dem sich die Enden des Henkels mit den als Lager dienenden Löchern auf den Ösen befinden. Dieser liegt in der Regel auf dem zylindrischen Teil der Öse entfernt von den Buckeln und den Schweißstellen, wenn der gebogene Henkel unter einer Biegespannung steht und somit seine Enden nach außen drückt. Ein besonderer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß ein nachträgliches umständliches Anbringen des Henkels beispielsweise durch Aufknöpfen der mit Löchern versehenen Enden des Henkels auf die Ösen oder ein nachträgliches Aufbörteln der Ösen zur Bildung von Halteflanschen gegen ein Herabrutschen der Enden der Henkel entfällt.The invention is based on the idea of a Handle made of plastic and a flange and intended as a journal for the handle First bring the eyelet together and then the eyelet the well-known hump welding process on the metal weld existing container. The welding process is done while the plastic existing handles already on the eyelet and thus in Welding area. During the welding process usually made of thermoplastic material existing handles are not damaged or melted. The resistance welding points formed on the humps do not lead to such an increase the temperature of the eyelet causing an impairment of the plastic handle. For this also contributes to the fact that the cold, on the Eye attached to the welding electrode during the welding process for heat dissipation from the eyelet straight in contributes to the area where the ends of the handle with those serving as camps Holes are located on the eyelets. This is usually on the cylindrical part of the eyelet away from the humps and the welds when the curved handle is under is subject to a bending stress and thus its ends outside presses. A particular advantage of the invention The procedure is that a subsequent cumbersome Attach the handle, for example, by unbuttoning it the ends of the handle with holes on the Eyelets or a subsequent crimping of the eyelets for formation of holding flanges to prevent the ends from sliding off the handle is omitted.
Eine besonders zweckmäßige Weiterbildung der Erfindung ist im Anspruch 2 gekennzeichnet und besteht darin, daß die Henkel unmittelbar vor dem Anbringen an die Behälter gebildet werden, indem ein Kunststoffband von einer Rolle abgewickelt und entsprechend der Länge der Henkel abgelängt wird, wobei beim oder nach dem Ablängen Löcher in die Enden der abgelängten Abschnitte des Kunststoffbandes eingebracht werden. Auf diese Weise entfällt ein aufwendiges, kompliziertes Transportieren und Orientieren vorgefertigter Henkel zu dem Ort des Anbringens, wobei das Abwickeln des Bandes von einem Wickel und Zuführen zu dem Ort des Ablängens keine besonderen Schwierigkeiten bereitet.A particularly useful development of the invention is characterized in claim 2 and consists in that the handles immediately before attaching them to the containers be formed by a plastic tape from a roll unwound and cut to length according to the length of the handles , holes in or after being cut to length the ends of the cut sections of the plastic tape be introduced. In this way, a complex, complicated transportation and orientation of prefabricated Handle to the place of attachment, being unwinding the tape from a wrap and feed to that No particular difficulty in cutting to length.
Grundsätzlich ist es möglich, die Henkel an die Behälter
anzubringen, während sich diese bewegen. Zweckmäßig
ist es jedoch, gemäß der Weiterbildung nach Anspruch 3 die
Bildung der Henkel und/oder die Anbringung an die Behälter
bei pilgerschrittartiger Bewegung der Henkel und/oder Behälter
zu bewirken. Die die einzelnen Verfahrensschritte
bewirkenden Vorrichtungen und Werkzeuge können somit ortsfest
sein.Basically, it is possible to attach the handle to the container
attached while they are moving. Appropriately
it is, however, according to the training according to

Anhand der Zeichnungen soll das erfindungsgemäße Verfahren
anhand eines Ausführungsbeispiels einer prinzipiell
dargestellten Vorrichtung gemäß der Erfindung zur Durchführung
dieses Verfahrens näher erläutert werden.
Fig. 1 zeigt ein Kunststoffband 1 aus steifem Material,
das von einem nicht dargestellten Wickel abläuft und
durch Transportmittel in Form von Walzen 2 und 3 in Richtung
eines Pfeiles 4 in eine durch eine strichpunktierte
Linie nur schematisch angedeutete Ablängeinrichtung 5
transportiert wird, die das Kunststoffband 1 in einzelne
Stücke ablängt, von denen eines als Henkelstreifen 6 gezeigt ist.
Beim Ablängen stanzt die Ablängeinrichtung 5 gleichzeitig
Löcher 7 in die Enden der abgelängten Stücke.1 shows a
Unterhalb der abgelängten Henkelstreifen 6 befindet sich ein
Transportband 8, das, wie das insbesondere in Verbindung
mit Fig. 2 ersichtlich ist, Behälter 9 in Richtung eines
Pfeiles 10 quer zur Richtung des Kunststoffbandes 1 bzw.
des Henkelstreifens 6, angedeutet durch Pfeil 4, pilgerschrittartig
bewegt. Durch eine Vorrichtung 11 wird jeweils ein
Henkelstreifen 6 einer Buckelschweißvorrichtung 12 zugeführt und
dabei in eine Henkelform gebogen: Ein so gebogener Henkel
ist in Fig. 1 mit der Bezugsziffer 13 versehen und in Fig.
3 mit Blick auf seine Seite gezeigt.Below the cut handle strips 6 is a
Aus Fig. 1 ist zu ersehen, daß oberhalb der gebogenen
Enden der Henkel 13 jeweils Reihen von Ösen 14 und 15 zugeführt
werden, die nach Vereinzelung durch nicht dargestellte
Mittel jeweils in eine Position gebracht werden,
in der sie mit den Löchern in den Enden der Henkel 13
fluchten. In dieser Stellung sind zwei Ösen 16 und 17 gezeigt.
Sie bestehen jeweils aus einem zylindrischen Teil,
an dessen dem Behälter 9 zugewandten Stirnkante sich Buckel
befinden, also kleine Erhebungen, die bei einem späteren
Schweißvorgang die punktförmigen Schweißstellen bilden.
An ihrem dem Behälter 9 abgewandten Ende weisen die
Ösen 16 und 17 jeweils Flansche auf, die ein späteres Abrutschen
der Enden der Henkel 13 von den Ösen 16 bzw. 17
verhindern, wenn diese als Lagerzapfen an dem Behälter 9
angeschweißt sind.From Fig. 1 it can be seen that above the curved
Ends of the
In Fig. 1 sind jeweils mit den Ösen 16 und 17 und auch
mit den Löchern in den Enden des Henkels 13 fluchtende
Schweißelektroden 18 und 19 angeordnet, die an ihren vorderen
Enden jeweils Zentrierzapfen aufweisen, die zur Zentrierung
der Ösen 16 und 17 dienen und in der Zeichnung
nicht erkennbar sind, da sie verhältnismäßig klein sind.
Die Schweißelektroden 18 und 19 befinden sich in der
Buckelschweißvorrichtung 12, die in Fig. 2 gezeigt ist. In
dieser Buckelschweißvorrichtung 12 sind auch Gegenelektroden
vorgesehen, die in der Zeichnung nicht dargestellt
sind und zur Durchführung des Schweißvorganges von oben
jeweils in einen Behälter 9 eingeführt werden, so daß sie
dann ein Gegenlager für die Schweißelektroden 18 und 19
darstellen.In Fig. 1 are each with the
Bei Durchführung des Verfahrens und Betrieb der in den
Fig. 1 und 2 dargestellten Vorrichtung wird schrittweise
ein Kunststoffband 1 durch die Walzen 2 und 3 in Richtung
des Pfeiles 4 in die Ablängeinrichtung 9 geführt, die so
an den Enden mit Löchern 7 versehene Henkelstreifen 6 erzeugt.
Diese werden gebogen und mit ihren Enden in eine Befestigungsposition
jeweils zu einem Behälter 9 geführt, der
schrittweise durch Transportband 8 herangeführt wird. Von
der Reihe von Ösen 14 und 15 wird jeweils eine zu der Befestigungsposition
geführt, wo in Fig. 1 gerade die Ösen
16 und 17 dargestellt sind. Dann werden die Schweißelektroden
18 und 19 in Richtung auf den Behälter 9 bewegt, so
daß die Ösen 16 und 17 in die damit fluchtenden Löcher in
den Henkel 13 bewegt und mit ihren Buckeln gegen die Wandung
des Behälters 9 gedrückt werden, wobei die nicht gezeigten
Gegenelektroden das Gegenlager bilden. Durch den
durchgeleiteten Schweißstrom erfolgt im Bereich der Buckel
eine Verschweißung der Ösen 16 bzw. 17 mit dem Behälter 9,
ohne daß der Kunststoff des Henkels 13 im Bereich seiner
Enden beeinträchtigt wird. Dies vor allem auch deshalb,
weil die Schweißelektroden 18 und 19 eine Wärmeableitung
und damit Kühlung bewirken. Nach dem Schweißvorgang werden
die Schweißelektroden zurückgezogen und die Gegenelektroden
aus dem Behälter 9 nach oben bewegt, wonach der Behälter
9 durch das Transportband 8 um einen Schritt in Richtung
des Pfeiles 10 (siehe Fig. 2) bewegt wird. Dadurch
wird ein weiterer Behälter auf dem Transportband 8 unter
die Buckelschweißeinrichtung 12 bewegt und in der beschriebenen
Weise mit einem neu zugeführten Henkel versehen.When performing the procedure and operating the in the
