Description

PROCEDE DE RENFORCEMENT D'ARTICLES EN VERRE CREUX PROCESS FOR REINFORCING HOLLOW GLASS ARTICLES
La présente invention a trait à des articles en verre creux, présentant notamment certaines formes particulières. II s'agit plus précisément d'articles en verre creux qui, positionnés les uns à côté des autres avec la même orientation sur un même plan, sont susceptibles d'entrer en contact mutuel selon une surface de révolution. C'est le cas notamment de bouteilles coniques dans leur partie basse à partir de l'épaule (diamètre décroissant vers le fond) ; ainsi en est-il de bouteilles de vin de Bordeaux, de Pineau des Charentes, de Cognac ... De telles bouteilles posées verticalement sur leur fond sur un plan horizontal peuvent entrer en contact mutuel selon une bande horizontale périphérique dans la zone de l'épaule.The present invention relates to hollow glass articles, having particular particular shapes. More specifically, these are hollow glass articles which, positioned next to one another with the same orientation on the same plane, are capable of coming into mutual contact along a surface of revolution. This is particularly the case of conical bottles in their lower part from the shoulder (diameter decreasing towards the bottom); This is the case with bottles of Bordeaux wine, Pineau des Charentes, Cognac ... Such bottles placed vertically on their bottoms on a horizontal plane may come into mutual contact along a peripheral horizontal band in the area of the vineyard. shoulder.
D'autre part le procédé de fabrication d'articles en verre creux intègre généralement deux étapes visant à améliorer la protection des articles vis-à-vis de la rayure, notamment avec des articles identiques lors du stockage, de la manipulation (remplissage ...), du transport.On the other hand, the process for manufacturing hollow glass articles generally incorporates two steps aimed at improving the protection of the articles from scratching, in particular with identical articles during storage, handling (filling, etc.). .), transportation.
Le traitement à chaud consiste à déposer sur la bouteille à 5000C environ, entre la machine I. S. (Individual Section) et la roue de transfert, un revêtement d'oxyde métallique, tel qu'oxyde d'étain. Ce revêtement contribue à renforcer la peau du verre.The heat treatment consists in depositing on the bottle at approximately 500 ° C., between the machine IS (Individual Section) and the transfer wheel, a coating of metal oxide, such as tin oxide. This coating helps to strengthen the skin of the glass.
Sa fonction principale est cependant de servir de primaire d'adhérence pour le revêtement à froid. Ce dernier est déposé en sortie d'arche de recuisson, sur les bouteilles à 1200C environ, lors du traitement à froid. Le revêtement à froid est en général un polymère appliqué par pulvérisation, qui donne un caractère glissant à la surface de verre, protège de l'abrasion et empêche la formation de rayures, et finalement préserve la résistance au choc et à la pression interne de l'article.Its main function, however, is to serve as adhesion primer for cold coating. The latter is deposited at the outlet of the annealing arch, on the bottles at about 120 ° C., during the cold treatment. Cold coating is generally a spray applied polymer which gives the glass surface a slipperiness, protects against abrasion and prevents the formation of scratches, and finally preserves the impact and internal resistance of the glass surface. Article.
Cependant, bien qu'ainsi traités à chaud et à froid, les articles de formes particulières mentionnées précédemment ne doivent pas frotter les uns sur les autres lors de leur stockage ou transport, à vide ou remplis, ou lors de leur manipulation (remplissage ...). Sinon, on observe sur leur bande horizontale périphérique de contact mutuel, dans la zone de l'épaule, une abrasion du verre sous forme de rayures et du dépôt de poudre de verre entraînant un défaut d'aspect, appelé rodage, ne permettant pas une exploitation des articles. On est donc amené à mettre en œuvre des moyens complexes, longs et coûteux en particulier pour le conditionnement des articles. On utilise des plateaux thermoformés dans lesquels les bouteilles s'emboîtent sans se toucher les unes les autres, ou bien encore on emploie des croisillons adaptés dans le même but de séparer les bouteilles les unes des autres. L'utilisation de plateaux thermoformés ou de croisillons requiert un développement spécifique ; elle constitue une dépense supplémentaire.However, although treated hot and cold, the articles of particular forms mentioned above should not rub on each other during storage or transport, empty or filled, or when handling (filling .. .). Otherwise, there is observed on their peripheral horizontal strip of mutual contact, in the shoulder area, abrasion of the glass in the form of scratches and deposition of glass powder resulting in a defect in appearance, called lapping, not allowing a exploitation of articles. It is therefore necessary to implement complex means, long and expensive especially for the packaging of articles. Thermoformed trays are used in which the bottles fit together without touching each other, or alternatively adapted braces are used for the same purpose of separating the bottles from each other. The use of thermoformed trays or braces requires specific development; it constitutes an additional expense.
D'autre part, on sait que les revêtements de protection du verre mentionnés ci-dessus, en particulier le revêtement à froid, peuvent constituer une gêne pour le collage des étiquettes. En effet, les colles aqueuses adhèrent difficilement au revêtement à froid, hydrophobe.On the other hand, it is known that the glass protection coatings mentioned above, in particular the cold coating, can be an inconvenience for sticking the labels. In fact, aqueous adhesives hardly adhere to the cold, hydrophobic coating.
L'invention a donc pour but de supprimer le rodage de produits en verre creux de géométrie particulière décrite ci-dessus, lorsqu'ils sont stockés, manipulés et transportés en contact les uns avec les autres sans utiliser de plateaux thermoformés ni de croisillons. L'aspect des produits doit alors être excellent, compatible avec le commerce de produits de luxe. D'autre part la facilité de collage des étiquettes ne doit pas être affectée.The object of the invention is therefore to eliminate the break-in of hollow glass products of particular geometry described above, when they are stored, handled and transported in contact with each other without the use of thermoformed trays or braces. The appearance of the products must be excellent, compatible with the trade of luxury products. On the other hand the ease of sticking labels should not be affected.
Ce but est atteint par l'invention, qui a donc pour objet un procédé de fabrication d'articles de série en verre creux qui, positionnés les uns à côté des autres avec la même orientation sur un même plan, sont susceptibles d'entrer en contact mutuel selon une surface de révolution. Ce procédé se distingue par le fait qu'après la sortie des articles de l'arche de recuisson, ils sont mis en rotation sur un tour au moins selon l'axe de ladite surface de révolution, cette dernière étant alors revêtue d'une couche additionnelle diminuant le coefficient de friction par un procédé sans contact solide.This object is achieved by the invention, which therefore relates to a method of manufacturing hollow glass series articles which, positioned next to each other with the same orientation on the same plane, are likely to come into contact with each other. mutual contact according to a surface of revolution. This process is distinguished by the fact that after the exit of the articles of the annealing arch, they are rotated on a lathe at least along the axis of said surface of revolution, the latter being then coated with a layer additional reducing the coefficient of friction by a method without solid contact.
Les inventeurs ont donc découvert qu'une surépaisseur de revêtement diminuant le coefficient de friction, comparable au revêtement à froid classique précité, pouvait suffire à empêcher la formation de rayures et le dépôt de poudre de verre dans la région de contact mutuel des articles. Une telle surépaisseur suffisante n'est pas visible à l'œil nu, l'aspect des articles fabriqués selon le procédé de l'invention est compatible avec le commerce de produits de luxe (vin, parfum ...).The inventors have thus discovered that a coating thickness decreasing the coefficient of friction, comparable to the aforementioned conventional cold coating, could be sufficient to prevent the formation of scratches and the deposition of glass powder in the region of mutual contact articles. Such a sufficient extra thickness is not visible to the naked eye, the appearance of articles manufactured according to the method of the invention is compatible with the trade of luxury goods (wine, perfume ...).
Le traitement de l'invention permet une palettisation simple des articles en verre creux, c'est-à-dire par exemple et à titre indicatif la disposition et mise sous film thermoplastique de cinq lits superposés de 15 x 15 bouteilles en contact les unes avec les autres, sans déplorer de rodage significatif après tout transport habituel. Chaque lit est délimité par un simple élément de carton contre les bords duquel les bouteilles des côtés sont en butée. Les bouteilles sont disposées de manière la plus compacte possible. On n'utilise ni plateaux thermoformés ni croisillons coûteux.The treatment of the invention allows a simple palletization of the hollow glass articles, that is to say for example and as an indication the arrangement and setting thermoplastic film of five bunk beds of 15 x 15 bottles in contact with each other, without lamenting significant break-in after any usual transport. Each bed is delimited by a simple piece of cardboard against the edges of which the bottles of the sides are in abutment. The bottles are arranged as compact as possible. No thermoformed trays or expensive braces are used.
Le traitement de l'invention est localisé, car la surface de révolution selon laquelle les bouteilles peuvent se toucher est en général une bande relativement étroite à hauteur de l'épaule, c'est-à-dire représente une fraction limitée de la surface extérieure. La ou les zones de collage d'étiquette ne sont pas concernées, et ainsi évite-t-on tout problème de décollement d'étiquette ou de tenue de décor.The treatment of the invention is localized, since the surface of revolution in which the bottles can touch each other is generally a relatively narrow band at shoulder height, i.e., a limited fraction of the outer surface area. . The label bonding zone (s) are not affected, and thus any problem of label peeling or decoration keeping is avoided.
L'emploi d'un procédé de revêtement sans contact solide garantit l'obtention d'une couche additionnelle régulière et homogène, donc de qualités optique et mécanique maximales.The use of a coating process without solid contact ensures the obtaining of a regular and homogeneous additional layer, thus of maximum optical and mechanical qualities.
De préférence, ladite surface de révolution est revêtue de ladite couche additionnelle en position de l'article dans la machine de contrôle optique.Preferably, said surface of revolution is coated with said additional layer in position of the article in the optical control machine.
Selon des modes de réalisation préférés du procédé :According to preferred embodiments of the method:
- ladite surface de révolution est revêtue de ladite couche additionnelle par un procédé de projection de gaz et/ou de liquide, réactif ou nonsaid surface of revolution is coated with said additional layer by a method of spraying gas and / or liquid, reactive or not
(on peut employer un aérosol, c'est-à-dire une suspension de particules liquides dans un gaz porteur ou dans l'air) ; on peut citer à titre d'exemple la pulvérisation non réactive de liquide à une température de ladite surface de révolution comprise entre 20 et 1000C ;(An aerosol can be used, ie a suspension of liquid particles in a carrier gas or in air); exemplary non-reactive spraying of liquid at a temperature of said surface of revolution between 20 and 100 0 C;
- on laisse sécher ladite couche additionnelle après son application, en l'absence de tout contact solide avec ladite couche additionnelle pendant son séchage.said additional layer is allowed to dry after its application, in the absence of any solid contact with said additional layer during its drying.
Ces réalisations préférées sont mises en œuvre de manière particulièrement pratique en revêtant de ladite couche additionnelle ladite surface de révolution en position de l'article sur le dernier poste de la machine de contrôle optique, qui doit alors mettre l'article en rotation. En effet la machine de contrôle optique comporte plusieurs postes de contrôle non nécessairement tournants, mais dont certains peuvent être fixes. Sorti du dernier poste de la machine de contrôle optique, l'article n'est alors soumis à aucun autre contact solide que celui de son fond sur le convoyeur. Ladite surface de révolution est libre de tout contact solide, le séchage de ladite couche additionnelle peut avoir lieu dans les conditions préférées. Sont donc évités de préférence une application et un séchage de ladite couche additionnelle avec contact solide tels qu'une application par chiffon ou support poreux tel qu'éponge, ou séchage avec essuyage. Ainsi peut-on obtenir un revêtement de caractéristiques mécaniques - adhésion, cohésion et résistance à l'abrasion - optimales et du plus bel aspect. De manière avantageuse, les organes de contrôle optiques sont isolés de la zone de revêtement de ladite couche additionnelle par un rideau d'air.These preferred embodiments are implemented in a particularly practical manner by coating said additional layer with said surface of revolution in position of the article on the last station of the optical control machine, which must then rotate the article. Indeed the optical control machine has several checkpoints not necessarily rotating, but some may be fixed. Released from the last post of the optical control machine, the article is then subjected to no other solid contact than that of its bottom on the conveyor. Said surface of revolution is free of any solid contact, the drying of said additional layer can take place under the preferred conditions. It is therefore preferable to avoid application and drying of said additional layer with solid contact, such as an application with a rag or a porous support such as sponge, or drying with wiping. Thus one can obtain a coating of mechanical characteristics - adhesion, cohesion and resistance to abrasion - optimal and the most beautiful appearance. Advantageously, the optical control members are isolated from the coating area of said additional layer by an air curtain.
Le procédé spécifique de l'invention se combine idéalement à un traitement à chaud et un traitement à froid mentionnés dans la partie introductive ci-dessus. Ainsi les articles sont-ils de préférence munis d'un premier revêtement entre la machine I. S. et la roue de transfert. Ce revêtement à chaud consiste en oxyde métallique obtenu par dépôt chimique en phase gazeuse réactif de précurseurs sur les articles à environ 5000C. Des précurseurs utilisés sont par exemple SnCI4, respectivement TiCI4 pour des revêtements à chaud de SnO2, respectivement TiO2. Ce dépôt est réalisé dans un tunnel placé sur le convoyeur.The specific process of the invention is ideally combined with a heat treatment and a cold treatment mentioned in the introductory part above. Thus the articles are preferably provided with a first coating between the machine IS and the transfer wheel. This hot coating consists of metal oxide obtained by reactive chemical phase deposition of precursors on the articles at about 500 ° C. The precursors used are for example SnCl 4 or TiCl 4 for hot coatings of SnO 2 or TiO respectively. 2 . This deposit is made in a tunnel placed on the conveyor.
De plus, les articles sont de préférence munis d'un second revêtement diminuant le coefficient de friction, après leur sortie de l'arche de recuisson et avant leur passage dans la machine de contrôle optique. Ce revêtement à froid est de type éphémère (acide oléique, stéarates) ou au contraire permanent (cires ou vernis - cires de polyéthylène) vis-à-vis de la tenue à la pasteurisation, stérilisation. Il est appliqué par pulvérisation sur les articles à 1200C environ.In addition, the articles are preferably provided with a second coating decreasing the coefficient of friction, after their exit from the annealing arch and before their passage through the optical control machine. This cold coating is ephemeral (oleic acid, stearates) or permanent (waxes or varnishes - polyethylene waxes) vis-à-vis the resistance to pasteurization, sterilization. It is applied by spraying on the articles at approximately 120 ° C.
L'invention a également pour objet un article en verre creux qui, positionné à côté d'un article semblable de même orientation, sur un même plan, est susceptible d'entrer en contact avec celui-ci selon une surface de révolution présentant une épaisseur maximale de revêtement diminuant le coefficient de friction. Bien que des mesures d'épaisseurs ne soient pas aisées, notamment parce que le revêtement à chaud présente fréquemment des irrégularités compensées par le revêtement à froid, on entend ici par « épaisseur maximale », une épaisseur de revêtement à froid substantiellement plus importante, en moyenne au moins 1 ,5 fois plus importante jusqu'à plus de 3, voire 5 fois plus importante que sur les parties de la surface extérieure autres que ladite surface de révolution.The subject of the invention is also a hollow glass article which, positioned next to a similar article of the same orientation, on the same plane, is capable of coming into contact with the latter in a surface of revolution having a thickness maximum coating decreasing the coefficient of friction. Although thickness measurements are not easy, in particular because the hot coating frequently has irregularities compensated by the cold coating, here "maximum thickness" means a thickness of substantially higher cold coating, on average at least 1, 5 times greater to more than 3 or 5 times greater than on parts of the outer surface other than said surface of revolution.
De préférence, l'article en verre creux de l'invention est une bouteille, un flacon ou un pot dont ladite surface de révolution représente au plus 50%, de préférence au plus 30% de la surface extérieure. La surface de contact entre les articles est donc relativement faible, laissant une proportion complémentaire de la surface extérieure non revêtue d'une épaisse couche de traitement à froid relativement importante, sur laquelle le collage d'étiquettes ou la tenue de décors n'est pas spécialement difficile.Preferably, the hollow glass article of the invention is a bottle, a bottle or a pot of which said surface of revolution represents at most 50%, preferably at most 30% of the outer surface. The contact surface between the articles is therefore relatively small, leaving a complementary proportion of the uncoated outer surface of a relatively large thick cold-treatment layer, on which the sticking of labels or the holding of decorations is not especially difficult.
Un autre objet de l'invention consiste en un ensemble de conditionnement d'articles en verre creux décrits ci-dessus et/ou obtenus par le procédé décrit ci-dessus, vides ou remplis, positionnés les uns à côté des autres avec la même orientation sur un même plan, en contact mutuel selon leurs dites surfaces de révolution. Un tel ensemble de conditionnement revêt par exemple la forme d'une palette constituée de plusieurs lits superposés étroitement et solidairement entourés d'un film thermoplastique résistant. Chaque lit comprend un fond de carton avec des prolongements latéraux formant des butées pour les articles situés sur les côtés du lit. Cet ensemble de conditionnement est simple et économique.Another object of the invention consists of a set of packaging hollow glass articles described above and / or obtained by the method described above, empty or filled, positioned next to each other in the same orientation on the same plane, in mutual contact according to their so-called surfaces of revolution. Such a packaging assembly is for example in the form of a pallet consisting of several superimposed beds closely and integrally surrounded by a resistant thermoplastic film. Each bed comprises a cardboard bottom with lateral extensions forming stops for items located on the sides of the bed. This packaging set is simple and economical.
Les bénéfices procurés par l'invention sont décrits dans l'exemple suivant. ExempleThe benefits provided by the invention are described in the following example. Example
On transporte des palettes de bouteilles de Pineau des Charentes traitées ou non selon l'invention, constituées de cinq lits superposés de 15 x 15 bouteilles.Pallets of Pineau des Charentes bottles treated or not treated according to the invention are transported, consisting of five superimposed beds of 15 x 15 bottles.
Toutes les bouteilles sont soumises à un traitement à chaud et à froid classique.All bottles are subjected to conventional hot and cold treatment.
Le revêtement à chaud consiste en Snθ2 obtenu par dépôt chimique en phase gazeuse (CVD) sur les bouteilles à 5000C environ, à partir du précurseur SnCI4. Son épaisseur moyenne approximative est de 22 nm. Le revêtement à froid est une cire de polyéthylène additivée adaptée à un dépôt sur substrat à 80 - 1500C, à 1 ,5 % en poids dans l'eau.The hot coating consists of SnO 2 obtained by chemical vapor deposition (CVD) on the bottles at 500 ° C., from the SnCl 4 precursor. Its average approximate thickness is 22 nm. The cold coating is an additivated polyethylene wax adapted to a substrate deposition at 80-150 ° C., at 1.5% by weight in water.
Les zones de contact mutuel des bouteilles traitées conformément à l'invention reçoivent en plus la pulvérisation de cire de polyéthylène commercialisée par la société Rohm and Haas sous la référence Polyglass D4333, à 2% en poids dans l'eau. Le substrat est à température ambiante notamment comprise entre 20 et 400C. La pulvérisation est effectuée dans le dernier poste de la machine de contrôle optique.The zones of mutual contact of the bottles treated in accordance with the invention additionally receive the polyethylene wax spray marketed by Rohm and Haas under the reference Polyglass D4333, at 2% by weight in water. The substrate is at ambient temperature, especially between 20 and 40 ° C. The spraying is carried out in the last station of the optical control machine.
On compare le rodage des bouteilles traitées ou non selon l'invention après un transport routier d'environ 800 kms, selon l'échelle suivante :The running-in of treated or untreated bottles according to the invention is compared after a road transport of about 800 km, according to the following scale:
0 = parfait0 = perfect
1 = acceptable - 2 = limite1 = acceptable - 2 = limit
3 = mauvais3 = bad
Les résultats sont consignés dans le tableau ci-dessous, sous forme du pourcentage de bouteilles dans chaque degré de cotation de la gravité du rodage.The results are shown in the table below, as the percentage of bottles in each degree of severity rating.
L'efficacité du traitement de l'invention est ainsi démontrée. The effectiveness of the treatment of the invention is thus demonstrated.
