Description

Die Erfindung bezieht sich auf ein Gehäuse, insbesondere Druckbehälter, mit einem Schild, das von hinten eingeprägte Schriftzeichen aufweist und mittels einer Klebstoffschicht am Gehäuse befestigt ist, die beim Aufbringen des Schildes in die Prägevertiefungen eingedrungen ist und auf ein Verfahren zur Anbringung des Schildes.The invention relates to a housing, in particular pressure vessel, with a sign which has characters embossed from behind and is fastened to the housing by means of an adhesive layer which penetrated into the embossing depressions when the sign was applied, and to a method for attaching the sign.

Bei einem bekannten Gehäuse dieser Art (DE-PS 29 11 529) wird das Schild mittels einer heiß härtbaren Klebstofffolie an der Gehäuseoberfläche befestigt. Damit sich nicht nur eine dauerhafte Klebverbindung, sondern auch zumindest im Randbereich des Schildes eine das Eindringen von Feuchtigkeit verhindernde Dichtung bildet, wird das Schild während des Aushärtens mit erheblichem Preßdruck, vorzugsweise etwa 350 N/cm2, auf die Klebstoffolie gedrückt. Hierbei ergibt sich eine elastische Verformung, so daß ein Teil des Klebstoffs auch in die Vertiefungen der eingeprägten Schriftzeichen dringt und dort aushärtet.In a known housing of this type (DE-PS 29 11 529) the shield is attached to the surface of the housing by means of a heat-curable adhesive film. So that not only a permanent adhesive connection, but also a seal preventing the penetration of moisture forms at least in the edge region of the sign, the sign is pressed onto the adhesive film during curing with considerable pressure, preferably about 350 N / cm 2 . This results in an elastic deformation, so that part of the adhesive also penetrates into the depressions in the embossed characters and hardens there.

Bei bestimmten Gehäusen, wie bei Druckbehältern, besteht die Vorschrift, daß dauernd eine Identifikation möglich sein muß. Aus diesem Grund gingen die Bestrebungen bisher dahin, die mit der Beschriftung versehenen Typenschilder so dauerhaft wie möglich am Gehäuse zu befestigen. Trotzdem trat gelegentlich der Fall auf, daß das Typenschild vom Gehäuse abriß, beispielsweise aufgrund äußerer Gewalt. In einem solchen Fall mußte das Gehäuse zum Hersteller eingesandt werden, der nach aufwendigen Untersuchungen ein neues Schild anbrachte.With certain housings, such as with pressure vessels, there is a requirement that identification must be possible at all times. For this reason, efforts have so far been made to attach the inscribed type plates to the housing as permanently as possible. Nevertheless, there was occasionally a case in which the nameplate tore off the housing, for example due to external force. In such a case, the housing had to be sent to the manufacturer who, after extensive investigations, attached a new label.

Aus der LU-A-48148 is bereits ein Nummernschild für kraftfuhrzunge bekannt, das so aufgebaut ist, daß die Buchstaben und Zahlen auch nach einem Umfall oder einem Brand noch identifizierbar sind. Dabei geht es aber nicht darum, daß das Schild abreißen könnte, sondern vorwiegend darum, daß es verbrennt.From LU-A-48148 a license plate for power tongue is already known, which is constructed so that the letters and numbers can still be identified even after an accident or a fire. The point is not that the shield could tear off, but primarily that it burns.

Der Erfindung liegt die Aufgabe zugrunde, ein Gehäuse der eingangs beschriebenen Art anzugeben, bei dem nach Abreißen des Schildes eine einfachere Identifizierung möglich ist.The invention has for its object to provide a housing of the type described above, in which a simpler identification is possible after tearing off the shield.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Klebstoff und die Oberflächenbeschaffenheit von Gehäuse und Schild so aufeinander abgestimmt sind, daß die Haftfestigkeit zwischen Klebstoffschicht und Gehäuse und die Eigenfestigkeit der Klebstoffschicht größer sind als die Haftfestigkeit zwischen Schild und Klebstoffschicht.This object is achieved in that the adhesive and the surface properties of the housing and shield are coordinated so that the adhesive strength between the adhesive layer and housing and the inherent strength of the adhesive layer are greater than the adhesive strength between the shield and adhesive layer.

Bei dieser Zuordnung ist sichergestellt, daß eine äußere Kraft, die ein Ablösen des Schildes mit sich bringt, immer zu einer Trennfläche zwischen Schild und Klebstoffschicht führt. Infolgedessen verbleibt auf dem Gehäuuse ein Klebstoffschichtsiegel, das an der Oberfläche erhaben die Schriftzeichen des Typenschildes darbietet. Das Gehäuse ist daher auch nach Abreißen des Schildes identifizierbar. Man kann daher auf die Anbringung eines neuen Schildes verzichten oder aber ohne Schwierigkeiten ein neues Schild mit den vom Siegel ablesbaren Daten anbringen.This assignment ensures that an external force, which brings about a detachment of the sign, always leads to a separating surface between the sign and the adhesive layer. As a result, an adhesive layer seal remains on the housing, which presents the characters on the name plate on the surface. The housing can therefore be identified even after the label has been torn off. It is therefore possible to dispense with the attachment of a new label or, without difficulty, to attach a new label with the data readable from the seal.

Bei bekannten Klebstoffverbindungen wurde nicht darauf geachtet, daß die Eigenfestigkeit der Klebstoffschicht und die Haftfestigkeit an den beiden Oberflächen der Klebstoffschicht eine bestimmte Beziehung zueinander haben. Die Folge davon war, daß beim Abreißen des Schildes die Oberfläche der Klebstoffschicht zerstört wurde.In the case of known adhesive bonds, no care has been taken to ensure that the inherent strength of the adhesive layer and the adhesive strength on the two surfaces of the adhesive layer have a certain relationship to one another. As a result, the surface of the adhesive layer was destroyed when the shield was torn off.

Besonders günstig ist es, als Klebstoff einen Zweikomponentenkleber zu verwenden, insbesondere einen Zweikomponentenkleber, der als Grundstoff Methylmetacrylat enthält. Ein solcher Zweikomponentenkleber besitzt eine außerordentlich hohe Eigenfestigkeit, so daß keine Gefahr besteht, daß beim Abreißen des Schildes der Klebstoff reißt. Darüber hinaus ist ein Zweikomponentenkleber beim Auftragen so weich, daß er sich mit großer Genauigkeit in die Vertiefungen der in das Schild eingeprägten Schriftzeichen eindrücken läßt. Entsprechend gut ist die spätere Lesbarkeit nach dem Abreißen des Schildes. Hierbei sollte die Klebstoffschicht eine Dicke von etwa 1 mm haben, also zwischen 0,8 und 1,2 mm liegen. Dies verhilft zu einer ausreichenden Eigenfestigkeit der Klebstoffschicht und sorgt für genügend Material zum Füllen der Prägevertiefungen.It is particularly favorable to use a two-component adhesive as the adhesive, in particular a two-component adhesive which contains methyl methacrylate as the base material. Such a two-component adhesive has an extraordinarily high inherent strength, so that there is no danger that the adhesive will tear when the label is torn off. In addition, a two-component adhesive is so soft when applied that it can be pressed into the recesses of the characters embossed on the sign with great accuracy. The readability after tearing off the label is correspondingly good. The adhesive layer should have a thickness of approximately 1 mm, i.e. between 0.8 and 1.2 mm. This helps to ensure that the adhesive layer is sufficiently strong and provides enough material to fill the embossing recesses.

Günstig ist es, wenn das Schild eine glattere Oberfläche hat als das Gehäuse. Dies kann beispielsweise dadurch geschehen, daß das Schild walzglatt und das Gehäuse gerauht ist. Unter sonst gleichen Verhältnissen ist die Haftfestigkeit gegenüber dem Gehäuse größer als gegenüber dem Schild.It is favorable if the shield has a smoother surface than the housing. This can happen, for example, in that the plate is smooth and the housing is roughened. Under otherwise identical conditions, the adhesive strength to the housing is greater than to the shield.

Insbesondere besteht das Schild aus aluminiertem Schwarzblech. Durch die Aluminiumoberfläche des Schwarzblechs ergibt sich eine weitere Differenzierung der Haftfestigkeit auf beiden Seiten der Klebstoffschicht.In particular, the sign is made of aluminized black plate. The aluminum surface of the black plate further differentiates the adhesive strength on both sides of the adhesive layer.

Günstig ist es auch, wenn die Schnittkante des Schildes durch einen Wulst aus ausgehärtetem Klebstoff abgedeckt ist. Man kann also den Klebstoff dazu verwenden, die Schnittkante so zu umschließen, daß das Schild nicht vom Rand her zu rosten beginnt.It is also favorable if the cut edge of the sign is covered by a bead of hardened adhesive. So you can use the glue to enclose the cut edge so that the sign does not start to rust from the edge.

Ein Verfahren zur Anbringung des Schildes an einem Gehäuse ist erfindungsgemäß dadurch gekennzeichnet, daß eine vorgegebene Menge des Zweikomponentenklebers, dessen Komponenten unmittelbar vor der Abgabe gemischt wurden, auf das Gehäuse aufgebracht und durch Andrücken des Schildes so auseinandergedrückt wird, daß sich ein Wulst ringgs um das Schild bildet.A method of attaching the shield to a housing is characterized in that a predetermined amount of the two-component adhesive, the components of which were mixed immediately before being dispensed, is applied to the housing and pressed apart by pressing the shield such that a bead surrounds it Shield forms.

Durch die dem Abgabevorgang unmittelbar vorgeschältete Vermischung der beiden Komponenten ist eine gleichmäßige Aushärtung und daher eine gleichmäßige Eigenfestigkeit der Klebstoffschicht gewährleistet. Durch das Abmessen der vorgegebenen Menge und das anschließende Auseinanderdrücken ergibt sich von selbst eine Klebstoffschicht der gewünschten Dicke und ein das Schild umgebender Wulst. Dieser Wulst hat, selbst wenn er den Umfang des Schildes nicht umschließt, den Effekt, daß äußere Kräfte weniger leicht am Schild angreifen können, und daher ein Abreißen des Schildes generell erschwert wird.The mixing of the two components, which precedes the dispensing process, ensures uniform curing and therefore a uniform intrinsic strength of the adhesive layer. By measuring the predetermined amount and then pushing it apart, an adhesive layer of the desired thickness and a bulge surrounding the shield are obtained. This bead has even if it does not encircle the circumference of the shield, the effect that external forces are less likely to attack the shield, and it is therefore generally more difficult to tear off the shield.

Zweckmäßigerweise werden Gehäuse, Schild und Klebstoffschicht etwa 5 bis 8 Minuten in einem auf 80 bis 100°C beheizten Ofen gehalten. Dies führt in sehr kurzer Zeit zu einer ausreichenden Aushärtung des Klebstoffschicht.The housing, shield and adhesive layer are expediently held in an oven heated to 80 to 100 ° C. for about 5 to 8 minutes. This leads to sufficient hardening of the adhesive layer in a very short time.

Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten, bevorzugten Ausfürhungsbeispiels näher erläutert. Es zeigen:

  • Fig. 1 einen Teilquerschnitt durch ein erfindungsgemäßes Gehäuse,
  • Fig. 2 eine Draufsicht auf das montierte Schild,
  • Fig. 3 den Querschnitt der Fig. 1, nachdem das Schild abgerissen ist, und
  • Fig. 4 eine Draufsicht auf das Klebstoffsiegel.
The invention is explained in more detail below with reference to a preferred exemplary embodiment shown in the drawing. Show it:
  • 1 shows a partial cross section through a housing according to the invention,
  • 2 is a plan view of the assembled shield,
  • Fig. 3 shows the cross section of Fig. 1 after the shield is torn off, and
  • Fig. 4 is a plan view of the adhesive seal.

Gemäß Fig. 1 ist die Wand 1 eines Gehäuses 2 mit einem Schild 3 versehen, das mittels einer Klebstoffschicht 4 an der Oberfläche 5 befestigt ist. Das Gehäuse 2 ist beispielsweise ein Druckbehälter, wie Druckluftbehälter für Bremsanlagen, der für einen bestimmten zulässigen Betriebs- Überdruck ausgelegt ist. Das Schild 3 ist ein Typenschild, das alle wesentlichen Daten, die zur Identifizierung des Gehäuses erforderlich sind, mit erhabenen Schriftzeichen 6 trägt. Diese Schriftzeichen werden von der Rückseite eingeprägt, so daß sich dort Vertiefungen 7 ergeben. Im Ausführungsbeispiel besteht die Wand 1 aus Stahlblech und das Schild 3 aus aluminiertem Schwarzblech.1, the wall 1 of a housing 2 is provided with a shield 3 which is fastened to the surface 5 by means of an adhesive layer 4. The housing 2 is, for example, a pressure container, such as compressed air containers for brake systems, which is designed for a certain permissible operating pressure. The label 3 is a type label that bears all the essential data required to identify the housing with raised characters 6. These characters are embossed from the back, so that there are 7 recesses. In the exemplary embodiment, wall 1 is made of sheet steel and shield 3 is made of aluminized black sheet.

Die Klebstoffschicht 4 besteht aus einem Zweikomponentenkleber, der im Ausführungsbeispiel als Grundstoff Methylmetacrylat enthält. Zur Härtung können beispielsweise Peroxide verwendet werden. Solche Zweikomponentenkleber werden beispielsweise unter der Bezeichnung "Agomet F 310" von der Degussa angeboten. Die Klebstoffschicht hat eine Dicke von etwa 1 mm und besitzt am Rand einen Wulst 8, der die Schnittkante 9 des Schildes 3 abdeckt.The adhesive layer 4 consists of a two-component adhesive which contains methyl methacrylate as the base material in the exemplary embodiment. For example, peroxides can be used for curing. Degussa offers such two-component adhesives, for example, under the name "Agomet F 310". The adhesive layer has a thickness of about 1 mm and has a bead 8 on the edge, which covers the cutting edge 9 of the shield 3.

Zum Anbringen des Schildes 3 wird wie folgt vorgegangen:The procedure for attaching the shield 3 is as follows:

Die Oberfläche der Wand 1 wird durch Sandstrahlen gerauht und gegebenenfalls entfettet. Das Schild 3 ist walzglatt und lediglich mit den eingeprägten Schriftzeichen 6 versehen. Mittels einer Auftragvorrichtung wird eine abgemessene Menge des Zweikomponentenklebers, dessen Komponenten erst unmittelbar vor dem Austritt miteinander gemischt worden sind, auf die Wand 1 aufgetragen. Alsdann wird das Schild 3 angedrückt, wodurch sich die Klebstoffschicht ausbreitet, bis sich am Rand der Wulst 8 bildet. In dieser Stellung, gegebenenfalls unter leichtem Druck, wird die Anordnung für 5 bis 8 Minuten in einem Ofen gehalten, dessen Temperatur zwischen 80 und 100°C liegt. Alsdann kann die Anordnung weiterbehandelt werden. Wenn beispielsweise die Wand 1 den Klöpperboden eines Druckbehälters darstellt, kann dieser Boden anschließend in üblicher Weise mit einem zylindrischen Mantel verschweißt werden. Der so fertiggestellte Behälter kann dann mit einer Schutzschicht versehen und durch einen Brennofen geleitet werden, ohne daß dadurch die dauerhafte Befestigung des Schildes an der Wand 1 leidet.The surface of the wall 1 is roughened by sandblasting and, if necessary, degreased. The shield 3 is whale smooth and only provided with the embossed characters 6. By means of an application device, a measured amount of the two-component adhesive, the components of which were only mixed with one another immediately before the outlet, is applied to the wall 1. Then the shield 3 is pressed, causing the adhesive layer to spread until the bead 8 forms at the edge. In this position, possibly under slight pressure, the arrangement is kept for 5 to 8 minutes in an oven whose temperature is between 80 and 100 ° C. The arrangement can then be processed further. If, for example, the wall 1 represents the dished bottom of a pressure vessel, this bottom can then be welded to a cylindrical jacket in the usual way. The container thus finished can then be provided with a protective layer and passed through a kiln without the permanent attachment of the sign to the wall 1 thereby suffering.

Wenn durch irgendwelche äußeren Kräfte das Schild 3 abreißt, erfolgt die Trennung an der Fläche 10 zwischen Klebstoffschicht und Schild, weil die Haftfestigkeit an der Fläche 11 zwischen Gehäuse und Klebstoffschicht größer ist als die Haftfestigkeit an der Fläche 10 zwischen Klebstoffschicht und Schild und weil auch die Eigenfestigkeit der Klebstoffschicht 4 größer ist als die letztgenannte Haftfestigkeit. Infolgedessen verbleibt die Klebstoffschicht 4 als Siegel mit erhabenen Schriftzeichen 12, die durch das Eindringen des Klebstoffes in die Vertiefungen 7 der Schriftzeichenprägungen 6 entstanden sind. Infolgedessen sind auf dem am Gehäuse verbleibenden Siegel 4 sämtliche Angaben des Schildes 3 lesbar.If the shield 3 tears off due to any external forces, the separation takes place on the surface 10 between the adhesive layer and the shield, because the adhesive strength on the surface 11 between the housing and the adhesive layer is greater than the adhesive strength on the surface 10 between the adhesive layer and the shield, and also because The inherent strength of the adhesive layer 4 is greater than the last-mentioned adhesive strength. As a result, the adhesive layer 4 remains as a seal with raised characters 12, which are created by the penetration of the adhesive into the recesses 7 of the character embossments 6. As a result, all the information on the label 3 can be read on the seal 4 remaining on the housing.

Das Schild kann auch aus Aluminium oder einem anderen Metall oder aus Kunststoff bestehen, sofern gegenüber der Klebstoffschicht eine geringere Haftfestigkeit gegeben ist als zwischen Gehäuse und Klebstoffschicht.The label can also be made of aluminum or another metal or plastic, provided that the adhesive layer has a lower adhesive strength than between the housing and the adhesive layer.
