DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a method new and improved of applying codes to preferably flat objects, for example, textile webs, foils, fabrics, strips, window frames, profiled parts or the like. The invention also relates to an arrangement for performing this method.
Such codes can serve, for example, for conducting the marked or coded objects or products during processing thereof to corresponding processing operations or storage locations. Regarding the objects, all those come in question which possess a surface or flat surface portion providing adequate space for applying a code marking, and which are movable past a marking or code forming arrangement. Preferably, mass-produced articles and assembly line articles are marked in such a manner.
SUMMARY OF THE INVENTION
With the foregoing in mind, it is a primary object of the present invention to provide a new and improved method of, and arrangement for, applying codes to an object and which method and arrangement are not afflicted with the drawbacks and limitations of the prior art.
Another and highly significant object of the present invention is directed to the provision of a new and improved method of, and arrangement for, applying codes to an object and which method and arrangement result in highly durable and distinctly readable codes or code markings on such object.
A further important object of the present invention aims at providing a new and improved method of, and arrangement for, applying codes to an object and which method and arrangement particularly permit applying to flat web-type objects code markings which are distinctly readable by means of a scanning or reading device during processing operations or on an assembly line carrying such flat or web-like objects.
A still further important object is directed to providing a new and improved construction of a scanning arrangement for scanning codes or code markings and which scanning arrangement is particularly suited for scanning the codes or code markings which have been applied by carrying out the new and improved method using the new and improved arrangement for applying codes to an object.
Now in order to implement these and still further objects of the invention, which will become more readily apparent as the description proceeds, the method of the present development is manifested, among other things, by the features that for forming a code, preferably a bar code, with the aid of a bonding agent, for example, a thermoplastic adhesive, a two-component adhesive, an adhesive solution or the like, glass beads are applied to the objects in the form of a code, such glass beads having a diameter of 0.01 mm to 1.0 mm, preferably 0.05 mm to 0.8 mm, particularly 0.08 mm to 0.5 mm, and having a refractive index greater than 1.5, preferably 1.85 to 2.0.
The arrangement for performing the method is characterized according to the invention in that the arrangement comprises an application or dispensing device for glass beads having a diameter of 0.01 mm to 1.0 mm, preferably 0.05 mm to 0.8 mm, particularly 0.08 mm to 0.5 mm, and having a refractive index greater than 1.5, preferably 1.85 to 2.0.
In this simple manner there is set up an arrangement of simple construction, by means of which a readily identifiable and accurately readable code can be applied, which code is attached by simple means and readily adheres to objects of varied surfaces. In particular, long material webs can be provided with such codes at a single or at several locations and then can readily be identified. With the arrangement according to the invention, it is rendered possible in simple manner to apply a code to a stationary or to a moving object. The glass spheres used for this purpose are readily detectable. The refractive index and the diameter are advantageously adapted or selected such that the focus of an electromagnetic scanning radiation, particularly light incident at the glass beads for detecting the code, is located within the glass spheres.
It is possible, for example, that the adhe
