Device for labeling individual products

Abstract

The invention relates to a device (1) for labeling individual products (2), in particular packages or goods, comprising a feed device (3) for transporting a respective product (2} along a transport route, comprising a label dispensing device (4) for providing a label (5), and comprising a label application device (6) having a blow head (7) for application of the label (5) to the surface of the product (2), wherein the blow head (7) has a blow head housing (8) having a pressure chamber (9), wherein the blow head housing (8) has, on the side directed towards the feed device (3), a housing part (10) having a plurality of housing openings (11) which connect the interior of the pressure chamber (9) to the environment of the blow head (8) and through which a pulse of compressed air in a ventingdirection (A) from the housing openings (11) to the feed device (3) can escape, wherein the pressure chamber (9) has a compressed air connection (12) for introducing compressed air into the pressure chamber (9), and wherein the label application device (6) has at least one slide element (13, 14, 15) which is movable between a first position, in which the slide element (13, 14, 15) can completely block at least some of the housing openings (11), and a second position, in which the slide element (13, 14, 15) can at least partially expose a plurality of these housing openings (11). In order to simplify the structure of such a device (1), according to the invention holes (16, 17, 18) are provided in the at least one slide element (13, 14, 15), which holes are arranged in such a way that in thesecond position of the slide element (13, 14, 15) the holes can be made to at least partially overlap the housing openings (11) which in the first position can be blocked by the slide element (13, 14, 15), and in the first position of the slide element (13, 14, 15) said holes are offset with respect to these housing opening (11), so that no overlap is provided. The invention further relates to amethod for labeling individual products (2).

Description

technical field [0001] The invention relates to a device for labeling individual products, especially parcels or goods, having a feed device for transporting each product along a transport path, a label dispensing device for providing labels and a device for Label application device of a nozzle for applying a label on the surface of a product, wherein the nozzle has a nozzle housing provided with a pressure chamber, wherein the nozzle housing has a housing part provided with a plurality of housing openings on the side directed to the feed device, the housing openings being able to Connect the interior of the pressure chamber with the surrounding environment of the nozzle housing and leak a compressed gas pulse in the exhaust direction from the housing opening to the feed device through the housing opening, wherein the pressure chamber has a compression chamber for introducing the compressed gas into the pressure chamber. The gas pipeline and wherein the label applying device h...

AI Technical Summary

Problems solved by technology

[0009] A disadvantage of the previously described prior art is that the operator has to adjust the nozzle or the housing opening necessary for the compressed gas pulse individually and with high precision for each different label size

This is especially complicated by the manual adjustment

[0010] All in all, the devices known from the prior art for labeling individual products are very complex in construction and relatively complex to operate
