Abstract

Dans ce procédé d'impression de barils par report, qui produit une impression résistante pour l'essentiel aux produits chimiques, à l'eau de mer et aux intempéries, on reporte une couche de laque colorée sur un baril. In this barrels printing process with reference, which produces a strong impression essentially to chemicals, sea water and weather, it delays a colored lacquer layer on a barrel. Cette couche de laque colorée à une ou plusieurs composantes et qui a de préference des propriétés thermoplastiques, est appliquée sur un support intermédiaire par sérigraphie, suivie d'une opération de réticulation. This layer of colored lacquer to one or more components and which preferably has thermoplastic properties is applied on an intermediate carrier by screen printing, followed by crosslinking operation. Lors de l'impression, la face imprimée du support intermédiaire est pressée contre le baril à imprimer au moyen d'un cylindre échauffé, ce qui permet de reporter la couleur. When printing, the printed side of the intermediate carrier is pressed against the barrel to be printed by means of a heated cylinder, which allows to extend the color. On obtient ainsi une impression de qualité. quality printing is thus obtained. Ce procédé permet d'étiqueter de manière fiable des barils. This process allows label reliably barrels. Les inscriptions reportées demeurent parfaitement lisibles lorsque les barils ainsi imprimés subissent une exposition de longue durée à l'influence de solvants, de l'eau de mer, de la lumière, ainsi que celle d'autres phénomènes analogues. Deferred entries remain legible when printed barrels and undergo long-term exposure to the influence of solvents, sea water, light, and that of other similar phenomena.

Description

A process for printing drums

The present invention relates to a process for printing drum, in particular metal barrels, wherein the essential and novel criteria of loading druckung to chemicals, seawater and Wetterfestig- ness and resistance against otherwise how include kau¬-extremist action. The printing is done by means of transfer printing with special paints, two-component included.

Until now, printing, in particular the multi-color printing on standard drums for industrial products, as well as for the disposal of such as petroleum, chemical, or other caustic substances, fraught with difficulties because of their bulkiness and the Unfestigkeit the printed product. It is known to print such ser Fäs¬ monochrome or at most two colors, but the second color can easily have a register difference of several millimeters. The Druck¬ quality did not meet international requirements in general. In particular imprints of barrels of dangerous chemicals, among others ge resistant as possible must gen exposure to light, weather, sea water and chemicals ver¬ schiedenster be so that the labels are perfectly readable even after a prolonged outdoor storage and after egg nem sea transport.

The object of the present invention is therefore the provision of a printing process for barrels, which fulfills the above requirements.

It is particular object of the present inventions dung that a barrel can be printed multicolored with a normal Farb¬ spectrum and with minimum font size of 2 to 3 mm. The procedure must rationally durch¬ can be performed, for example, during a waste filling. The Pressure uss withstand the acid test, and meet the mentioned strength criteria.

The present invention is demzu¬ follow a method for substantially chemicals, sea water and weather resistant printing drums, which is characterized in that a single- or Mehr¬ component color lacquer layer is printed on an intermediate carrier, to a barrel is transmitted by the printed side of the intermediate carrier is contacted with the bedrucken- to the barrel under heating in contact.

The new Fassbedruckverfahren is a printing process Transfer¬. It is preferably a dye composition Zu¬ containing a sulimierbare dye component used. Alternatively, is also a Zweikompo- nentenfarbe, optionally with a content of a Haft¬ means such as an adhesive lacquer, rubber-based, in question. Dei dye composition is printed on transfer paper or film. For an efficient printing process wer¬ the sets superiors in the form of rolled-up webs, the latter. The printing on the transfer paper or the Trans¬ ferfolie is effected by means of a known Papier¬ printing process. The printed film will be used later for the Transfer a one- or multi-colored printing on the barrels. This printing can take place before, during or after the filling process. It may be employed untreated, degreased metal drums or pre-painted barrels. The inventive method is also suitable for printing on plastic drums, so¬ remote withstand the plastic of the Uebertragungstemperatur in the process.

When Transmit operation is min¬ generally used least one heatable roll, which is part of a Spezialtranεfermaschine. It is normaler¬ example by rollers of conventional design, which have been adapted to the present process. The transfer machine may include one or more rollers. The present method is most often used for printing on the barrel outer wall. A steel drum preferably has Verstar- kung rib. Consequently, it can not be printed in its full height with a single roller. The problem-is solved in that rolls are used, the fin¬ place between the reinforcing ribs of the drums to.

The rollers have for the printing process, depending on the to be transmitted color, a temperature of 160 to 180 'C. The printing speed can be adapted to the Abfüllvor¬ gear and takes a barrel at least 1 min., Wherein the contact time of the hot roll of the transmitted color from 3 to 20 sec. Is. During the printing process the drum is mounted conveniently upright on a rotatable platform. Characterized the barrel during the transfer process is freely rotatable. In this way, a pressure around the whole barrel is possible.

As a paint for transfer printing is Kunst¬ resin enamels are suitable, such as EB-polyester barrel paint color with the item number 750.180.7101 Company Brillux Industrial Coatings in D - 5760 Arnsberg first

The transfer films or transfer papers are prepared by an ordinary paper printing method such as a screen printing method, wherein a multi-color printing can be employed. Inventions in the process according to the printed transfer paper or transfer sheets can be printed by a specialized company and in another operation, for example at the production site of the barrel content within the waste fill line for the printing of the barrels, can be used.

have proven to be advantageous to transfer sheets which are printed convey avoiding thermoplastic Binde¬ with sublimable dyes. This is usually to disperse dyes which sublime without decomposition 180-230 ° C. Such dyes are available from the dye manufacturers in various preparations, namely, as printing inks, solvent-based or aqueous printing pastes, or as components for preparing them. They are used for the transfer printing of textiles used ( "Sublistatic u method) whereby synthetic fibers such as lyesterfasern polyvinyl standing in the foreground. In the context of vor¬ lying invention it has been found that such dry transfer process especially for the printing of are barrels that are coated with polyester paint. This gives a very thin but durable paint film that can be carry aufge¬ with maximum precision.

Examples of suitable dyes for the dry transfer process Hostaprint (Hoechst), Lura- fix (BASF), Resiren (Bayer), or Subliscreen (Sericol).

In an advantageous embodiment, a transfer film with "Subliscreen SI" -Siebdruckfarbe (SERICOL GROUP Limited, Kent, GB) drive through a screen printing process is printed. A barrel, which is connected to EB-barrel polyester paint (product number 750.180.7101 the company Brillux industrial coatings in D - 5760 Arnsberg 1) is coated, is printed by means of the transfer film according to the here processes described. The temperature for the transfer process, which is carried out as described above, is approximately 220 ° C. In this case, a perfect and de¬ tailgetreuer pressure is obtained, which has excellent Lö¬ sungsmittel- and abrasion resistance.

Hereinafter, the inventive method is explained in more detail er¬ for example, by the accompanying figures. It shows

Fig. 1 is a perspective view of an arrangement of a barrel with transfer rollers, and FIG. 2 is a diagram of an arrangement for carrying out the Fassdruckverf TATIONS. In Figure 1, a barrel 1 to be printed with Uebertragungswalzen 2 a transfer machine 3 is darge provides. In the present arrangement can be seen that rollers 3 are necessary for the full Imprinted of the barrel, since the barrel 1 has two ribs. 4 These three rolls, it is possible to print the located between the ribs and the fold 5 and 6, part of the barrel side wall. During the printing process, the transfer paper or the transfer film between the roll 2 and the drum 1 comes to rest, wherein the roller is heated to the er¬ ford variable temperature of 160 to 220 ° C 2 and is pressed against the barrel. the pressure from the transfer paper or the transfer film is continuously transferred by rotating the roll or the drum.

Is a barrel finished printed, it is weiterbe¬ promotes and in its place the next barrel is brought to the printing position from Fördersystern.

Fig. 2 shows a schematic representation of an arrangement for carrying out the inventive proceedings. The barrels 1 are located on a conveyor belt, each drum 1 passes through a position in front of the transfer machine. 3 In this position the barrel is mounted for rotation about its axis. Of the roller 7 with the transfer medium 9 having the ink 10, the transport is fermedium led to a roller 8 for the empty transfer paper between the Uebertragungswalze 2 and the barrel. 1 During the printing process the Uebertragungswalze 2 is heated and pressed against the barrel. 1 In this case, is transmitted from the da¬ intermediate transfer medium 9 of the pressure 10 on the drum by the color components are melted and thereby bind to the surface of the barrel. In the printing process, the Uebertragungs¬ turn roller and the drum continuously. At the same time the transfer medium, after the color is transferred wound on the spool. 8 The illustrated in Fig. 2 Anord¬ voltage can be incorporated in a filling of an industrial operation. The print speed is brought into line with the filling speed.
