Description
Verfahren zum Herstellen von Globen, insbesondere Leuchtgloben sowie nach diesem Verfahren hergestellte Globen und Vorrichtung zum Herstellen von Groben, insbesondere Lauchtgloben. Process for the production of globes, in particular luminous globes and Globes made using this method and apparatus for making roughs, especially leek globes.
Die Erfindung betrifft ein Verfahren zum Herstellen von Gloin, insbesondere Leuchtgloben, bei dem die Globenhälften vorzugsweise im Bereich des Äquators miteinander verbunden werden.The invention relates to a method for producing gloin, in particular Illuminated globes in which the halves of the globe are preferably connected to one another in the area of the equator get connected.
Gegenstand der Erfindung bildet ferner ein nach den erfindungsgemä#en Verfahren hergestellter Globus, insbesondere Leuchtglobue sowie eine Vorrichtung zum Herstellen deratiger Globen. The subject matter of the invention also forms a according to the invention A globe produced by a method, in particular a luminous globe and a device for producing such globes.
Es sind aus Kunststoff-Folien bestende Folien bekannt, bei welche@ die Globushälften im Bereich des Äquators durch Schwei#en miteinander verbunden sind. Bei diesen bekannten Globen ist ein aus Kunststoff bestehender Äquatorring erforderlich, der nach dem Zusammenschwei#en und Beschneiden der Groben von Hand aufgebracht werden muß Diese bekannte Bauart besitzt den Nachteil, daß der lunatstoffring oft zerbricht und sich nur mit gröltei handwerklichem Geschick auf dem Globus anbringen lä#t. Trotzden ist die Verbindung zwischen den beiden Globushälften in der Regel wenig haltbar und besitzt ein unschönes Ausschen. Die umständliche Anbringung des Äquatorringes erhöht au#erden die Herstellkosten des Globus. Weiterhin wird durch die Verdiokung mittels des Äquatorringes eine unterschiedliche Lichtdurchlässigkeit geschaffen, was nich entsprechend nachteilig bei Leuchtgloben auswirkt.There are films consisting of plastic films known, in which @ the halves of the globe are connected to one another by welding in the area of the equator are. In these known globes there is an equator ring made of plastic required after welding and trimming the coarse by hand must be applied This known design has the disadvantage that the lunatstoffring breaks often and only with great craftsmanship can be attached to the globe. Nonetheless, there is the connection between the two halves of the globe usually not very durable and has an unattractive look. The awkward one Attachment of the equator ring also increases the manufacturing costs of the globe. Farther a different light transmission is achieved through the thickening by means of the equatorial ring created, which is not correspondingly disadvantageous for luminous globes.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren, einen Globus und eine Vorrichtung zur Herstellung von Globen zu schaffen, bei denen die den bekennten Bauarten anhaftenden Nachteile nicht mehr bestehen. Au#erdem bildet es Aufgabe der Erfindung, die Herstellkosten zu senken, den Ausachu# von Globen oder Globenteilen bei der herstellung herabzusetzen oder gänzlich zu verneiden sowie eine haltbare und formachöne Verbindung der Globushälften, insbesondere im Bereich des Äquators, zu schaffen. Eine besonders zweckmä#ige Verfahrensweise ergibt sich erfindungagemä# dadurch, daß die Globenhälften im Bereich des Äquators zunächst in einem Fre#- oder Prägevorgang mit einem au#en umlaufenden Flansch und einem innen umlaufenden Eingwulst verschen werden, worauf die Globenhälften im Bereich der Flansche und der Ringwulste mindestens teilweise miteinander durch Schwei#en verbunden und die äu-@eren Flansche anschlie#end entfernt werden. Hierdurch ergibt sich der Vorteil, daß die Globushälften lediglich durch die letztlich verbleibende Verschwei#ung im Bereich der Ringwulste gehalten werden, ohne daß nachträglich noch ein Äquatorring oder dergleichen auf den Globus aufgebracht und mit diesem z.B. durch Kleben verbunden zu werden braucht. Dadurch, da# die Verbindung bzw. die Schwei#naht in den Bereich der Ringwulste vorlegt ist, ergibt sich eine praktisch übergangslose Verbindung der Globushälften. Hierbei hat man es durch @ntsprechende Bemessung der Ringwulste der einander zugeordneten Globushälften praktisch in der Hand, die Schwei#naht mit einer für die Praxis völlig ausreichenden Stärke und/oder Haltbarkeit auszubilden, ohne daß sie von außen sichtbar ist.The invention is based on the object of a method, a globe and to provide apparatus for making globes in which those professed There are no longer any disadvantages inherent in construction types. It also forms the task of Invention to lower the manufacturing costs, the Ausachu # of globes or globe parts to be reduced or avoided entirely during manufacture, as well as a durable one and shapely connection of the halves of the globe, especially in the area of the equator, to accomplish. A particularly expedient procedure results from the invention. in that the halves of the globe in the area of the equator are initially in a Fre # - or Embossing process with an external flange and an internal bulge are given away, whereupon the halves of the globe in the area of the flanges and the annular bulges at least partially connected to each other by welding and the outer flanges can then be removed. This has the advantage that the globe halves only through the ultimately remaining welding in the area the annular bulges are held without an equatorial ring or the like is applied to the globe and connected to it, e.g. by gluing needs to become. Because the connection or the weld seam in the area the annular bulges is presented, there is a practically seamless connection of the globe halves. Here you have it by @ appropriate dimensioning of the annular bulges the associated halves of the globe practically in the hand, the weld seams with it to develop a strength and / or durability that is completely sufficient for practice, without it being visible from the outside.
Praktische Erfahrungen haben gssgigt, daß es für die Bedürfniete der Praxis ausreicht, wenn die Verbindung dadurch Schwei-#en nicht über den gesamten Umfang des Globus erfolgt. Vielmehr würde es bereits ausreichen, wenn die Globushälften an mshraren Bereichen der Ringwulste dadurch eine Schweißnaht mit etnander verbunden werden.Practical experience has shown that there is no need for the Practice is sufficient if the connection does not weld over the entire # Circumference of the globe is made. Rather, it would be enough if the halves of the globe A weld seam is thereby connected to each other at low areas of the annular bulges will.
Um zu verhindern, da# ein Lichtband am Äquator aus dem Globus austritt, empfichlt es sich, die bedruckten Kunststoff-Folien möglichst weit nach innen zu legen, damit die bedruckten Folien sich beim Vorgang des Pressens und Schweißens möglichst nahe kommen.To prevent a band of light from emerging from the globe at the equator, It is advisable to turn the printed plastic film as far inwards as possible lay so that the printed foils are in the process of pressing and welding come as close as possible.
Bei einer bevorzugten Ausführungsform der Erfindung wird die Bildung des Ringwulstes gleichseitig bzw. in einen ArbeitegaN mit der herstellung des flansches vorgenommen. Beim Pressen oder Prägen des Flansches fließt ober wölbt sich ein Teil de@ Materials zur Innenseite der Globushälfte hin und bildet hier den Ringwulst. Dies besitzt den Vorteil, daß unter Vermeidung mehrerer Arbeitsvorgänge die Flansche und Ringwulste gleichzeitig gebildet werden, was sich entsprechend vorteilhaft auf die Herstellungskosten auswirkt.In a preferred embodiment of the invention, the formation of the annular bead on the same side or in a work GAN with the manufacture of the flange performed. When the flange is pressed or stamped, a part flows or arches de @ Material towards the inside of the globe half and forms here the ring bead. This has the advantage that it avoids several operations the flanges and annular beads are formed at the same time, which is accordingly has a beneficial effect on manufacturing costs.
Ein besonders wichtiges Merkmal der Erfindung besteht darin, daß Schwei#werkzeuge nur an den äußeren Plansohen entlang geführt werden, wobei gleichzeitig eine Verschwei#ung der aneinander angeordneten Ringwulste der Globushälften erfolgt.A particularly important feature of the invention is that welding tools can only be guided along the outer planes, with welding at the same time the mutually arranged annular beads of the globe halves takes place.
Die Schwei#werkseuge erwärmen nicht nur den Kunststoff der nach au#en gerichteten Flansche der Globushälften, sondern die Wärme wird auch zu den inneren Ringwulsten weitergeleitet, so daß auoh im Bereich der Rinawulete eine Verschwei#ung stattfindet.The welding eyes not only heat the plastic outwards directed flanges of the globe halves, but the heat is also directed to the inner ones Ring beads passed on, so that also in the area of the ring beads there is a weld takes place.
Gemäß einen weiteren Merkmal der Erfindung wird bein Schwei#en ein Teil des Werkstoffes der Flansche - etwa von der äußeren Pläche des Globus ausgehend - nach außen sowie etwa keilförmig verdrängt. Hierdurch ergibt sich der Vorteil, daß beim chweißen kein oder kein wesentlicher Materialfluß nach innen um Globus erfolgt, so daß sich bei Schweißen kein unerwünschter innenliegender Ring bildet.According to a further feature of the invention, welding is used Part of the material used for the flanges - starting from the outer surface of the globe, for example - displaced outwards and approximately in a wedge shape. This has the advantage that when welding no or no substantial material flow inwards around the globe takes place so that no undesired inner ring is formed during welding.
Es hat sich als zweckmäßig erwiesen, wenn die Verschweißung der Globushälften durch kapazitive Hochfrequenzielstung vorgenommen wird.It has proven to be useful if the halves of the globe are welded together is made by capacitive high frequency power.
Ein weiteres Merkmal der Erfindung besteht darin, daß die Schwei#werkzeuge - vorzugsweise rollenförmige Schwei#elektroden - mit einem Abstand von etwa 0,2 bie 0,4 mm voneinander geführt werden/ Die Erfindung betrifft ferner minen nach dem erfindungsgemä#en Verfahren hergestellten Globus, insbesondere Leuchtglobus. Bin solcher Globue kennzeichnet sich gemäß einem weiteren Merkmal der Erfindung dadurch, daß der Globus aus nach außen hin im wesentlichen ebenflächig miteinander verschwei#ten Globuhälften besteht, während in dem Globus - vorzugsweise in Bereich des Äquators - die Globuehilften durch eine mindestens teilweise umlaufende Schwei#naht gehalten sind. Ein solcherma#en ausgebildeter Globus ist besonders haltbar, formschön und auch leicht ablesbar im Bereich des Äquators. Another feature of the invention is that the welding tools - preferably roll-shaped welding electrodes - with a distance of about 0.2 bie 0.4 mm from each other / The invention also relates to mines the globe produced by the method according to the invention, in particular a luminous globe. Such a globe is characterized according to a further feature of the invention in that the globe is essentially level with one another towards the outside welded halves of the globe, while in the globe - preferably in area of the equator - the globe aids by an at least partially circumferential weld seam are held. A globe designed in this way is particularly durable and elegant and also easy to read in the area of the equator.
Bei einer vorteilhaften Ausführungsform der Erfindung ist die im Globus angeordnet. Schweißnaht in den Globushälften zugeordneten, nach innen um ein begrenztes Ma# vorspringenden Ringwlsten angeordnet Gegenatand der Erfindung bildet ferner eine Vorrichtung zum Heretellen von Globen, insbesondere Leuchtgloben, mit liner Form bzw. Matrizen- und Patrizenteile zum mindestens teilweisen Bearbeiten der Globenhälften. Gemäß einem Merkmal der Srfindung weiet das Matrizenteil einen Präge- oder Preßrand uS, dessen unten liegende Fläche zum Matrizeninnern etwa gleichmä#ig ansteigt, wobei der diesem Präge- bzw. Pre#rand zugekehrte Randabschnitt des Patrizenteils mit dem Präge bzw. Pre#rand einen keilförmigen Raum einschließt 9 dessen gedffnete Keilspitze zum Matrizeninneren weist. Vorteilhaft weist das Patrizenteil eine über den inneren, an der Keilspitze liegenden Ranteil nach innen vorspringende Schulter auf. Beim Zusammenpressen des Matrizen bzw. Patrizenteile wird das Material der betreffenden Globushälfte in den keilförmigen Raum gedrückt und füllt diesen praktisch aus. Gleichzeitig fließt oder wölbt eich ein gewisser Teil des Materials durch die offene Keilspitze in den Innenraum des Matrizenteils, wobei die innen überstehende Schulter des Patrizenteils zur Bildung des Ringwulstes beiträgt. In an advantageous embodiment of the invention, the im Globe arranged. Weld seam in the globe halves assigned to the inside a limited amount of protruding torus arranged counterpart of the invention also forms a device for the manufacture of globes, in particular luminous globes, With a liner shape or female and male parts for at least partial processing of the halves of the globe. According to one feature of the invention, the female part has one Embossing or pressing edge uS, the lower surface of which is approximately even towards the inside of the die increases, with the one facing this embossing or Pre # rand Edge section of the male part with the embossing or Pre # rand encloses a wedge-shaped space 9 whose opened wedge tip points towards the inside of the die. The male part advantageously has one protruding inwardly over the inner part of the ridge at the tip of the chisel Shoulder on. When the matrices or male parts are pressed together, the material becomes the relevant half of the globe is pressed into the wedge-shaped space and fills it practically out. At the same time, a certain part of the material flows or bulges through the open wedge tip into the interior of the die part, with the inside protruding shoulder of the male part contributes to the formation of the annular bulge.
Es hat sich als zweckmäßig erwiesen, wenn der dem Präge- bzw. PreS-rand des Matrizenteils zugekehrte Randabschnitt sowie die nach innen vorspringende Schulter des Patrizenteile etwa horizontal verlaufen. Ein weitere Merkmal besteht darin, daß die nach innen vorspringende Schulter und der dem Pre#- bzw.
