"Device for marking material webs ¹¹

The innovation relates to a device for marking material webs with numbers or characters by spraying or spraying on dyes.

In the specialist areas that deal with material webs, for example those metallic type or those made of chemical materials, it is imperative to mark the individual tracks. This The requirement arises both from the need to different material qualities one hand of the current marking to differentiate, as well as, with the same qualities, the production to be recorded in terms of quantity and billing.

So far, this has been done in the stamping process with embossing or printing stamps or by stencil stamping or that Stencil syringes. The method has disadvantages in terms of accuracy and durability not only because of its slowness, because that Stamping with elastic block letters depends on the reliability of the inking device. A signing at strongly tempered Materials (up to 1200 ° C) is even with the previous aids

not possible.

Since the production facilities, for example rolling lines, work at high running speeds of up to 500 m / s, this falls accordingly Material that has been rolled up into coils is the starting point for today's Labeling methodology is no longer fair. A coil is understood, especially in the rolling technology of metals, to be a tape wound on a core.

The innovation has set itself the task by means of a facility to enable contrasting digits or characters on material webs with high performance per unit of time, whereby the methodology of the Spraying of dyes is assumed.

The innovation solves this dose in that the dyes of group-wise arranged paint spray guns with wide-jet nozzle, each of which only forms part of the identification symbol the material web is injected or sprayed. The smallest text fields can be recorded by reducing the size accordingly.

A special feature of the innovation is that from the electronic A well-known arrangement of groups of sevens, from which all numbers from 0 to 9 can be formed by omitting them.

This transfer from the electronics to the technique of spray guns faced considerable concerns. The typeface areas are

sometimes relatively small, overlapping of the lines was to be feared, and there were concerns about the spray guns, consisting of paint dispenser, actual gun and wide-jet nozzle, in a compact design to be arranged in a function group in a sufficiently delimited function to one another.

It has surprisingly been found that such an arrangement is functional with high precision.

The figures explain an application example of the innovation. Show it: Figure 1 the group-wise arrangement of the paint spray guns,

FIG. 2 the basic figure of the number 8, made up of tick marks .

In the figure 1, the spray pattern is shown, which with the arrangement of Figure 2 is achieved.

Figure 2 is a view of the paint spray guns from below, wherein the outer frame represents the spray gun block, and the inner frame represents the nozzle image.

In principle, it is possible to set up the device manually after the innovation, operated mechanically or electronically. Is preferred after state-of-the-art technology, the electronic activation of the spray guns via the control valves, depending on the deliberately intended specification

of the symbol or number to be printed. Surprised is the high contour accuracy that can be achieved with the arrangement according to the innovation. Let go of the basic figure all digits from 0 to 9 and numerous symbols are formed.

The operation itself is easy as the paint spray guns are known as Element of the spray technology, as well as the valves used in them, have a high degree of reliability and accuracy.

A particular advantage is the reliable marking of hot coils, which is carried out with precision and accuracy up to 1200 ° C.
