Description

The invention relates to a labelling device for packaging materials, in particular order bags for photographic work according to the preamble of claim 1.

Labeling devices are integrated into a packaging line for the automatic processing of all types of packaged goods; i.e. labeling devices are linked to other packaging machines with an automatic workflow.

According to DIN 55 405, labels themselves are packaging aids for labeling packages or for providing information about the quantity, type, price, etc. of a product. These are therefore labeling agents, which is the generic term for packaging aids that label the package or package. Adhesive labels in particular are preferably used in the automatic packaging process. These adhesive labels have a pressure-sensitive adhesive coating on one side.

The labeling of packaging materials can be a process that precedes or follows the main process, i.e. the actual packing. In particular, if the labeling device in question is linked to a packaging line, the further transfer process of the packaging materials, in this case the order bags, must not be hindered by the labeling.

The present invention is based on the knowledge that for the purpose of further transfer it is advantageous if the order bags are not labelled lying down but in an upright position, since then

For example, by ejecting the order bags almost vertically, for example into a Eurobox, the further handling of the order bags is made significantly easier.

The present invention is therefore based on the object of creating a labeling device of the type mentioned at the outset, which can be integrated into an automatically running packaging line by connecting a printer that can apply the information to the labels.

This object is achieved according to the invention by a labeling device according to the characterizing part of the proposed claim 1.

Particularly preferred developments of the invention are characterized in the subclaims.

The present labeling device has a printer which is used to apply coded or uncoded information to the labels applied to a supply roll. This information is used to identify the package and the packaged goods, for example for automatic data capture. Furthermore, a device is provided for removing the labels from the supply roll and applying them to the order bag, whereby according to the invention, an approximately horizontally positioned support plate is arranged downstream of the printer, on which the printed label, removed from the supply roll, comes to rest with its adhesive surface facing the support plate, whereby detection means are arranged above the support plate, which are used to receive the

After labeling, the order bag can be ejected through a closable and openable ejection floor below the receiving space that aligns the order bag.

The invention will now be described in more detail with reference to the accompanying drawings, which show a particularly preferred embodiment of the invention.

According to the illustration in Figure 1, the labeling device according to the invention is designed in terms of linking

Automatic packaging processes are subject to a clear classification. According to Figure 1, packaging machines are systems that carry out processes related to packaging. These include main processes such as filling, closing and wrapping, as well as upstream and/or downstream processes that serve to produce packages that are ready for shipping, storage and/or sale. Packaging lines are therefore links of packaging machines with an automatic workflow.

The labeling of packaging, here for example photo bags, can be a process that precedes or follows the main process, the actual packing, i.e. the insertion of the photos into the order bag. If such a labeling device according to the invention is inserted into the automatic process, i.e. the other processing machines, it is referred to as a packaging line.

In diagram block "A" the packaging machines are recorded according to Figure 1. "C" indicates the main process, packing, while "B" and "D" show the upstream and downstream processes, respectively, into which the device according to the invention is to be grouped.

The schematic blocks ¹¹ E", "F", "G", "H" and "I" identify the machines for the main processes, namely, for example, forming machines (E), erecting machines (F), filling machines (G), closing machines (H) and wrapping machines (I). Depending on requirements, the device according to the invention can also be integrated into one of the main processes, for example if the label with the package information for closing

the pack is used. In this case, there is a variant of use of the device according to the invention according to schematic block "J", in which multi-function packaging machines are included. According to schematic block "K", the packaging line formed by packaging machines is identified.

Figure 2 shows an overview of machines for equipping, marking and securing packages and packages. Machines for equipping, marking and securing packages and packages are packaging machines in the sense of the definition given in DIN 8740, Part 1. Their functions are mainly downstream of the main processes, but can also occur as an upstream process. These machines are divided into the types of equipment, marking and securing packages and packages and are differentiated according to the working principles, transferring a textual or pictorial representation, labeling, foiling or encapsulating.

The labeling machines are therefore a subgroup of machines for equipping, marking and securing packages and packages, whereby the present invention particularly addresses the subgroup "machines for labeling in the area of area application of labels". Here, a distinction is again made between wet adhesive labeling machines, hot melt adhesive labeling machines and labeling machines for coated labels or pressure-sensitive adhesive labeling machines.

The designation I in the upper diagram block covers the machines for equipping, marking and securing packages and packages. While a diagram line leads to blocks II, VI, VII, VIII and IX, the machines for transferring a representation (II), printing machines (VI), embossing machines (VII), burning machines (VIII) and electrostatic printing machines (IX), according to the invention, the group of labeling machines according to diagram block III is of particular importance, since machines for labeling by applying labels to a surface (X), machines for labeling by applying labels at specific points (XI) and machines for labeling by loosely attaching labels (XII) are grouped here. The invention preferably relates to the group according to diagram block X, while the foil-wrapping machines marked in block IV and the encapsulating machines by pressing XIII or pressing on XIV included in block V are of secondary importance.

The following example refers to the pressure-sensitive adhesive labeling machines.

Figure 3 shows the labeling device according to the invention in a side view, partially broken away. A printer 12 can be seen. Starting from a supply roll 3, the labels 2 are fed to the printer 12 on their carrier strips 13. The supply roll 3 is located on a support arm 14 attached to the entire device, on which it is arranged so that it can be unrolled. The carrier strip 13 containing the labels 2 is introduced into the rear side 16 of the printer 12 via a deflection roller 15. The deflection roller is arranged so that it can move on a sliding guide 20 via its carrier 19 in order to avoid tensile stresses between the supply roll 3 and the printer 12.

and printer insertion from the carrier strip 13. According to the transfer information and individual order data, regarding quantity, recipient, price, etc., the corresponding information is applied to the label 2 within the printer 12. The label 2 is then separated from the carrier strip 13 and fed to the support plate 1, which is arranged horizontally in front of the printer or its output. The empty carrier strip 13 is fed to the collecting roll 18 via the deflection roller 17.

After being ejected from the printer 12, the label 2 comes to rest with its adhesive surface 4 facing downwards onto the support plate 1. The detection means 5, here vacuum suction cups, are arranged above the support plate 1 or the label 2 located on it. These are directed downwards onto the label 2 lying flat on the support plate 1. The support plate 1 then performs a lifting movement upwards in the direction of arrow A. At the same time, a vacuum is built up here and the label 2 is detected. The support plate 1 then moves downwards and the detection means 5 swivel by approx. 90 degrees in the direction of arrow B.

Of course, it is also possible to subject the detection means 5 themselves to a lifting movement, which would be somewhat more complex in terms of construction.

In the meantime, the presence of a photo or order bag 6 is detected by a detection device 11, here a light barrier. Then the pressure plate 8, which carries the detection device 5 together with its rotating shaft, moves in the direction of arrow C towards the photo bag 6 and the

Vacuum is switched off. The label 2 adheres to the application bag 6 through the adhesive surface 4. If the adhesive force of the label 2 is not sufficient, it can alternatively be blown off using a switching valve, which then applies pressure to the vacuum suction cups.

Figure 4 shows an enlargement of the detection means 5. The same elements are identified by the same reference numerals as in Figure 3.

Figure 4 shows the individual movement sequences again, with dashed lines showing the position of the detection means 5 pivoted by 90 degrees and the dashed two-dot line showing the feed movement of the pressure plate 8 onto the application pocket 6.

The present invention provides a labeling device which can be integrated into packaging lines in a rapidly efficient manner, since, regardless of the type of packaging, it can be labeled in almost any position, here for example vertical alignment.
