Machine for applying self-adhesive protective labels on certificates, index cards and the like

The present invention relates to a machine for the automatic transfer of self-adhesive protective labels, in particular of transparent labels, which are presented on a paper web and then with the largest Precision can be applied to a certificate, index card or a bank document, etc.

It is well known that such documents are often crumpled up or given creases, which in some Make reading the information printed on the documents difficult. Especially in the case of It is often advisable to add information or comments to bank deeds in the margin, which, however, are not be confused with the information or relevant remarks on the paper. aside from that it proves advantageous for all these documents, a label or a transparent protective coating to apply which, since they can no longer be removed at the same time also represents a protective measure against counterfeiting.

The application of a protective cover has already been attempted, but apart from a considerable expenditure of time, the application is not precisely and precisely aligned, with folds and creases occurring, which is often the case makes it difficult to read the document, especially if the information is provided by means of magnetic lettering and should be read accordingly.

Various attempts to apply the application automatically, did not show a good result with these clear labels, because often between the certificate

and the application label air bubbles remain or no precise alignment succeeds, what with exactly the same Disadvantages also applies when applying by hand.

The present invention therefore aims to provide an automatic application machine the protective labels on documents of the above-mentioned type, which is particularly simple training and works accurately, is economical and easy to maintain and especially the application of the labels with extreme accuracy at the specified location of the document and precisely aligned without wrinkling and wrinkling and inclusion of air bubbles occur.

According to the invention, this is achieved by means of a machine Achieved the aforementioned purpose, which has a roll from which a paper web is drawn off, which on a holds transparent, self-adhesive labels on its sides, a squeegee i.e. a scraper for the labels of the paper web, which is rolled up on a new roll, a drum with a perforated peripheral surface for suction of the labels separated from the web, the drum in synchronism with an infeed conveyor belt works for the documents on which a label is precisely aligned under pressure against a moving one Pressure element is applied, and which is provided with a releasable clamp, which the documents with the applied Lets the label fall into an appropriate collecting container.

The subject matter of the present invention results not only from the subject matter of the individual claims, but also from the combination of individual claims among themselves.

All information and characteristics disclosed in the documents, in particular, the spatial configuration shown in the drawings are considered essential to the invention claimed insofar as they are new, individually or in combination, compared to the state of the art.

In the following the invention is based on only a way of implementation drawings in more detail explained. Further features essential to the invention can be found in the drawings and their description and advantages of the invention.

sucks.

1 with the feeder roller is designated, one of which Paper web 2 is unrolled, on one side of which the self-adhesive labels 3 are placed at intervals.

The web 2 with the labels 3 leads over the tensioning and guide rollers 11 and 12 as well as a tensioning device with friction clutch 13 and arrives at a doctor blade 4, the front edge of which is conically pointed, at which the direction of movement of the paper web 2 is reversed; by means of further tension rollers 14 and the drive unit 15, the paper web 2 is spooled onto the roll 5 empty.

As can be seen when looking at the figures, the self-adhesive label 3, since it is made of stronger Material as the paper web 2 exists when the paper web 2 reaches the leading edge of the doctor blade 4 and its Direction of movement reverses, no curve upwards on the Squeegee 4, but sits slightly in a straight line to the right in Figures 1 and 2 of the web

2, and is thus perforated to the outer circumference of a Running drum 10 sucked; which with a drive is provided, such as a stepping motor 16, for example or another suitable drive, while with an aggregate for the purpose of creating a vacuum and thus the suction into the drum 10 is provided. Therefore, each label 3 arrives on the drum 10, the Center line is offset to center line of the label that comes off the squeegee so that each label is 3 µm a little protrudes outward towards the drum 10 ', as shown better at 18 in FIG. As you continue to turn the drum 10 reaches the label 3 with its protruding edge under a button 19, for example a photocell that detects the presence of a label and by means of a corresponding one Drive and a power unit of any known design, a conveyor belt 6 below puts into operation, which is driven accordingly by its own motor, and that on its top one Number of documents 7 bears. Therefore, one document 7 is placed in the desired position below the drum 10, where it comes to a stop against a pincer element 20, while the drum 10 hits the one below Certificate 7 applies the intended label 3. At this moment there are 10 below the drum opposite the pliers 20 a certificate 7 and a label

3 available to be applied. If you continue to rotate in unison, the pressure element is raised (Pressure roller 8) due to the drive of the element 21, for example an electromagnet, which apart from lifting

and the lowering of the pressure roller 8 also causes the opening and closing movement of the tongs 20, which is shown in FIG has its fulcrum. After the application process has been carried out on the certificate 7 by pressing the label 3, the electromagnet 21 lowers the pressure roller 8. The pliers 20 open and over the driver rollers the document which now consists of the document 7 with the label 3 attached falls into the document below Collection container 9.

The label 3 is either attached to a preferred location on the document 7, or on the entire document, depending on requirements or suitability.
