Description

[0001] Procedure for operating a labeling system

[0002] The present invention relates to a method for operating a labeling system according to the preamble of claim 1 and to a labeling system with a labeling device according to the preamble of claim 13.

[0003] The labeling system in question comprises at least one labeling device, which is designed in particular as a price labeling device. The labeling device is equipped, among other things, with a weighing arrangement, a dispensing arrangement, and a label application arrangement as functional units, which are intended for labeling the individual packages. A printer arrangement is provided for printing the labels, whereby printing can also be carried out depending on a weight value determined by the weighing arrangement.

[0004] To record the labeling processes performed by the labeling devices, parameters such as the operating time of the labeling device or the number of resources used, for example, the number of label strips consumed, are often used as a benchmark. Based on these parameters, further process planning can be carried out and the costs incurred in operating the labeling devices can be accounted for.

[0005] A challenge is that parameters such as the operating time of the labeling device or the number of used material strips can only be used to approximately determine the number of labeling processes actually performed. The number of successfully applied labels can vary considerably during operation. In addition to varying workloads and process speeds, errors can occur during labeling processes, meaning the number of labels used does not necessarily correspond to the number of successfully applied labels.

[0006] The invention is based on the problem of providing a method for operating a labeling system that allows for a largely accurate recording of the labeling processes. This problem is solved by the features of the characterizing part of claim 1.

[0007] The fundamental consideration is that the functional units of the labeling devices are equipped with sensors to monitor operation and determine operating values ​​related to the labeling process. In addition to controlling the functional units, these operating values ​​can be used to check whether a labeling process was successful. Based on the check, counter information is generated that only includes those labeling processes classified as successful. The counter information can therefore be used for improved resource planning and billing.

[0008] In detail, it is proposed that operating values ​​recorded during a respective labeling process are checked for the fulfillment of a predetermined completion criterion representing a successful labeling process and that the occurrence of a fulfilled completion criterion is stored in a counter information.

[0009] Incorrect application of the labels by the application assembly can be a reason why the number of successful labeling processes deviates from the total number of labels used. The preferred embodiment according to claim 2 therefore relates to operating values ​​of an applicator, for example a static applicator and / or a pendulum stamp, of the application assembly, which are checked using the final criterion. Operating values ​​to be preferably used for the final criterion are the subject of claim 3.

[0010] In the further, likewise preferred embodiment according to claim 4, a feed arrangement is provided for transporting the packages, the operating values ​​of which can be incorporated into the completion criterion. For example, a sufficient match between the feed speed and the application speed of the applicator can be a prerequisite for successful application.

[0011] Also preferred is the embodiment according to claim 5, according to which a label sensor is provided for detecting the applied label, so that the result of the labeling process can be determined in a simple and reliable manner. Particularly preferred is the use of a barcode scanner according to the embodiment according to claim 6, whereby the labeling process can be easily assessed by detecting and checking a barcode on the label.

[0012] In particular, the print image produced by printing or an alignment of the label achieved by application can also be checked on the basis of the label sensor, for example a camera, which is the subject matter of claim 7.

[0013] Claim 8 relates to the use of a printer sensor in the printer assembly, whereby faulty printing processes can be detected based on the operating values ​​of the printer assembly. In particular, labeling processes with faultily printed labels are not taken into account in the counter information or are at least marked accordingly.

[0014] Also interesting are the embodiments according to claims 9 to 11, according to which further information about the labeling process, such as a labeling process type, is assigned to the counter information. This facilitates, in particular, the compilation of incurred resources and costs.

[0015] In the preferred embodiment according to claim 12, the counter information, in particular with the associated information mentioned above, is stored in a production control system or transmitted to it. This allows for centralized recording of the counter information for multiple labeling devices.

[0016] According to a further teaching according to claim 13, which has an independent meaning, a labeling system with a labeling device is claimed, wherein the labeling system is preferably set up to carry out the proposed method.

[0017] It is essential that the labeling system is configured to check the operating parameters recorded during each labeling process for compliance with a predefined completion criterion representing a successful labeling process and to record the occurrence of a fulfilled completion criterion in a counter information. Reference is made to all explanations of the proposed procedure.

[0018] In the following, the invention is explained in more detail with reference to a drawing which merely illustrates exemplary embodiments. In the drawing,

[0019] Fig. 1 is a perspective view of the proposed labeling system for carrying out the proposed method and

[0020] Fig. 2 a) to c) schematic views of labels applied and printed in a labeling process.

[0021] The invention relates to a method for operating a labeling system 1. The labeling system 1 is equipped with at least one labeling device 2 for labeling individual packages 3, which is designed in particular as a price labeling device.

[0022] The labeling device 2 has a control arrangement 4, which controls functional units of the labeling device 2 (to be explained later) to carry out labeling processes. In one labeling process, a single package 3 is labeled. Preferably, a sequence of labeling processes for a set of respective packages 3 is carried out in a labeling routine.

[0023] A weighing arrangement 5 of the labeling device 2 serves to determine weight values ​​of the respective package 3. The weighing arrangement 5 has a load cell that determines representative, analog and / or digital weight values ​​for the weight of the package 3. The weight values ​​are determined in particular based on a deformation measurement of a support for the packages 3, for example via strain gauges, and / or based on electromagnetic force compensation of the weight of the respective package 3.

[0024] A dispensing arrangement 6 of the labeling device 2 is provided for dispensing a label 7, which can be designed to be detachable from a material strip 8. A label 7 detachable from a material strip 8 refers in particular to a label 7 which is detachably attached with its adhesive surface to a carrier strip that forms the material strip 8 and can consist, for example, of paper and / or plastic. It is also possible for the label 7 to be produced by separating a section from a printable or printed material strip 8, for example by cutting and / or tearing the material strip 8. In particular, labels 7 designed as adhesive labels are used, which already have an adhesive surface by means of which they are detachably attached to the material strip 8.It is also conceivable to use adhesive-free labels 7, which are only later provided with an adhesive surface or are applied to an adhesive surface on the respective package 3.

[0025] A printer assembly 9 of the labeling device 2 is provided for printing the label 7. Printing of the label 7 can in principle take place on the material strip 8 and / or after the label 7 has been detached from the material strip 8, as well as before, after, or during application of the label 7 to the respective package 3. Here, and preferably, a printer assembly 9 configured for thermal printing, in particular direct thermal printing or thermal transfer printing, is provided. Printing of the label 7 takes place depending on the weight values. For example, the label 7 is provided with weight information 10 upon printing, and / or a unit price 12 attributable to the package 3 is determined based on a base price 11 and printed on the label 7.

[0026] In addition, the labeling device 2, here in a common housing with the dispensing arrangement 6, has an application arrangement 13 as a further functional unit for applying the dispensed label 7 to the respective package 3. Preferably, the dispensed label 7 is picked up by a stamp, which here is preferably designed as a pendulum stamp 14, and applied to the respective package 3. In particular, the stamp has a blow head for sucking on and blowing off the label 7. During application, the pendulum stamp 14 performs a movement along a transport direction of the packages 3 in order to enable labeling of moving packages 3. With the application arrangement 13, the label 7 can be applied to the package 3 in a contact-like manner by pressing the label 7 onto the package 3.Additionally or alternatively, it is conceivable that the label 7 is applied without contact, for example by the blow head of the stamp blowing the label 7 onto the package 3 by generating a blast of compressed air directed towards the package 3.

[0027] A labelling process for a package 3 comprises at least the actions carried out by the aforementioned functional units controlled by the control arrangement 4:

[0028] Determining weight values ​​of the respective package 3 by means of a weighing arrangement 5;

[0029] Dispensing a label 7 by means of a dispensing arrangement 6;

[0030] Printing the label 7 by means of a printer arrangement 9 depending on the weight values; and

[0031] Applying the label 7 dispensed by the dispensing arrangement 6 to the respective package 3 by means of an application arrangement 13.

[0032] Preferably, the labeling process is carried out repeatedly for several packages 3 in a labeling routine.

[0033] It is now essential that the operating values ​​recorded during each labeling process are checked for the fulfillment of a specified completion criterion representing a successful labeling process and that the occurrence of a fulfilled completion criterion is stored in a counter information.

[0034] Here, and preferably, the labeling device 2, and in particular the aforementioned functional units of weighing arrangement 5, dispensing arrangement 6, printer arrangement 9, and / or application arrangement 13, have sensors 15 that monitor the functioning of the labeling device 2 and are used as a basis for control by means of the control arrangement 4. Operating values ​​are recorded by means of the sensors 15, which further serve to evaluate the respective labeling process.

[0035] The completion criterion generally represents a successful labeling process, which is mapped to the operating values. For example, a labeling process is only considered successful if one or more operating values ​​are within a specified value range. Operating values ​​can also directly represent an error condition, whereby the labeling process is only considered successful if such an operating value indicates an error-free labeling process. The counter information is indicative of the number of labeling processes considered successful according to the completion criterion test. In a simple embodiment, the counter information contains a numerical value that is incrementally increased upon occurrence of a fulfilled completion criterion, and thus upon occurrence of a labeling process considered successful.It is also conceivable that the counter information records the total number of all labelling processes, whereby the number of labelling processes assessed as inadequate as a failure to meet the completion criterion is deducted from the total number.

[0036] One aspect of a successful labeling process is the optimal application of the labels 7 by means of the application arrangement 13. In a preferred embodiment, the completion criterion relates to the operating values ​​of an applicator of the application arrangement 13. In principle, in an embodiment not shown, a static applicator can be provided, wherein the package 3 is moved relative to the applicator to apply the label 7. By moving the package 3 on the applicator, for example, a label 3 adhering to the package 3 can be detached from a material strip 8, for example in a rolling movement. In particular, a static applicator is integrated into the dispensing arrangement 6.

[0037] In the illustrated, preferred embodiment, a movable applicator is provided, which is configured to perform an application movement relative to the package 3. Here and preferably, the applicator is designed as a pendulum stamp 14.

[0038] The interaction of the applicator with the package 3 is of particular importance during application. The final criterion can be the presence of a label 7 on the applicator when the application assembly 13 applies the label to the package 3. This presence can be represented by an operating value. The application of the package 3 relates to the interaction between the applicator and the package 3, which can be contact-based or contactless.

[0039] The final criterion can relate to the application pressure of the applicator. In the case of a static applicator, the application pressure is understood to be, in particular, the contact pressure of the package 3 on the applicator. In the case of a movable applicator, the application pressure is understood to be, for example, the air pressure used by a pendulum punch 14 designed as a blow-pendulum punch. For example, insufficient negative pressure when sucking on the label 7 and / or insufficient air pressure when blowing off the label 7 can be an indicator of faulty application of the label 7. The same applies to the application height of the applicator for the respective package 3, in particular the stroke height of the pendulum punch 14, which relates to the position of the applicator relative to the surface of the respective package 3.In the movement of the pendulum punch 14, unintentional collisions between the blow head and the package 3 can also be detected, so that it can be concluded that the label 7 has been inadequately applied or has not been applied at all.

[0040] As a further functional unit, a feed arrangement 16 is preferably provided for transporting the respective packages 3. The feed arrangement 16 is preferably a belt conveyor or a roller conveyor, optionally also at least one robot arm, for moving the respective packages 3. The feed arrangement 16, here the belt conveyor, preferably has at least one conveyor belt 17, via which the respective packages 3 are transported along a transport direction.

[0041] Preferably, the labeling process further comprises the action: transporting the respective package 3 by means of the feed arrangement 16 at a feed speed when applying the label 7. The completion criterion can relate to a predetermined match between an application speed of the pendulum stamp 14 and the feed speed and / or an alignment of the respective package 3 on the feed arrangement 16.

[0042] A specified match of the speeds means, in particular, that the difference between the speeds does not exceed a specified maximum deviation, which can be a prerequisite for successful application. The feed speed can be determined via a motion sensor and / or via drive values ​​such as the drive current and drive voltage of the feed arrangement 16. The application speed of the pendulum ram 14 can be understood as the speed of the pendulum ram 14 in the transport direction at the time of application.

[0043] The alignment of the pack 3 on the feed arrangement 16 relates to the position of the pack 3 and in particular the orientation of the surface of the pack 3 relative to the label 7 to be applied. For example, a pack 3 placed twisted on the feed arrangement 16 can result in the label 7 being applied with an angular deviation or on the wrong side of the pack 3. Here and preferably, a pack sensor 18 is provided, which is preferably designed as a camera and determines image data on the packs 3 transported by means of the feed arrangement 16. The pack sensor 18 is here and preferably provided upstream of the application arrangement 13 in the transport direction.

[0044] The completion criterion can relate to the distance between consecutive packs 3 transported by the feed arrangement 16 and / or the number of packs 3 transported per unit of time. Packs 3 transported on the feed arrangement 16 can be detected by sensors, preferably via a light barrier or the like. If, for example, the distance between the packs 3 is too small for the feed speed, such as when a signature is detected indicating a predetermined minimum distance between the packs 3, and in particular when the packs 3 are adjacent to one another, it can be assumed that a successful labeling process for at least one of the packs 3 has failed.

[0045] In Fig. 1, according to a preferred embodiment, it is also shown that the labeling device 2 has a label sensor 19 for the applied, in particular printed, label 7. The completion criterion is checked here at least partially based on detection of the label 7 by the label sensor 19.

[0046] The label sensor 19 preferably has a barcode scanner that detects a barcode located on the label 7, in particular a printed barcode. Checking the completion criterion involves comparing the detected barcode with a barcode specification for the package 3. For this purpose, the barcode scanner can have a sensor control that decodes the detected barcode. The barcode specification can relate to at least part of the decoded information contained in the detected barcode. Through the comparison, the detected barcode, and thus the application of the label, can be classified as correct. It can also be determined that the barcode is readable but does not match the barcode specification or has a different format. Furthermore, the barcode can be classified as unreadable.Preferably, the labelling process is only taken into account in the meter information if the barcode is classified as correct.

[0047] It is also conceivable to design the label sensor 19 as a camera or the like. Using the label sensor 19, the result of the labeling process can be determined, in particular, via image data.

[0048] Preferably, the completion criterion relates to printing of the label 7 by the printer arrangement 9, in particular the occurrence of printing errors and / or an alignment of the generated print image.

[0049] Fig. 2a) shows an example of an optimally printed and applied label 7 on a package 3. Fig. 2b), on the other hand, shows a label 7 which, although optimally applied, is partially printed incorrectly. In area 20, a printing error is shown, which in this case is caused by an incorrectly controlled, consistently blackened pixel. In area 21, on the other hand, a missing pixel can be seen, so that part of the printed image is missing. The alignment of the printed image particularly affects the accuracy of centering the printed image on the surface of the label 7, which can also be detected using image data.

[0050] Furthermore, the completion criterion can relate to the orientation of the applied label 7 on the package 3, as indicated in Fig. 2c). The orientation of the applied label 7 here relates to the intended placement of the label 7 within a predetermined area of ​​the package 3. Likewise, the orientation can relate to a rotation of the label 7 to a predetermined angular position.

[0051] The results of labeling processes shown in Fig. 2b) and c) may result in a failure to meet the completion criterion, for example, detected by operating values ​​of the barcode scanner or camera, so that the corresponding labeling processes are not included in the counter information. Accordingly, the counter information only contains the labels 7 shown in Fig. 2a) that were applied and printed according to a specification depicted via the completion criterion.

[0052] Furthermore, the completion criterion can relate to the adhesion of the label 7 to the package 3 and / or the absence of a label 7. For example, the label sensor 19 is used to detect only partial adhesion, for example due to an insufficient adhesive surface, or a bent label 7. The absence of the label 7 can also be easily detected via the label sensor 19, for example, the barcode scanner.

[0053] In a further embodiment, it is provided that the printer arrangement 9 has a printer sensor 22 which detects operating values ​​of the printer arrangement 9 when printing the label 7, and that the completion criterion relates to the operating values ​​of the printer arrangement 9.

[0054] Preferably, the printer assembly 9 is configured for thermal printing, whereby the label 7 is color-changed, in particular blackened, by the application of localized heat at the location of the heat exposure. The localized heat exposure is achieved by one or more rows of heating resistors arranged in the thermal strip of the thermal head. The heating resistors can be monitored for functionality using the printer sensor 22. If there is a deviation in the electrical resistance value of a heating resistor, it can be concluded that the respective pixel (dot) has failed.

[0055] The printer assembly 9 can have a counter-pressure element, in particular in the form of a stationary bar or rotatable roller, with an insertion gap formed between the thermal bar and the counter-pressure element. Position values ​​of the counter-pressure element, which are determined, for example, via a position sensor, can be monitored and compared, in particular, with a dimension of the insertion gap specified for the respective label type. Further information relating to the respective labeling processes, for example, the time at which the respective labeling process was performed, can be assigned to the counter information. The assigned information can also be formed by operating values ​​and / or by variables derived from the operating values.

[0056] In one embodiment, it is provided that a labeling process type, in particular based on a label type of the applied label 7 and / or a print type of the printing of the label 7, is assigned to the respective labeling process on the basis of a predetermined assignment rule and is stored in particular for counter information.

[0057] The label type, for example, distinguishes between labels 7 of different formats, thicknesses, materials, and the like. The print type, for example, categorizes the printing of the label 7, for example, according to the respective print image, a proportion of blackened pixels in the total area of ​​the print image, or the like.

[0058] Furthermore, it is preferably provided here that quality measurement values ​​recorded by at least one sensor, in particular at least one of the aforementioned sensors 15, of the labeling device 2 with regard to the labeling process are checked for compliance with a predetermined quality criterion and that information about the compliance and / or the degree of compliance of the quality criterion is assigned to the labeling process, preferably that the information about the compliance and / or the degree of compliance of the quality criterion is stored as counter information.

[0059] While the final criterion check primarily yields binary information (labeling process successful / unsuccessful), the quality criterion can provide a more detailed classification of the labeling process. The quality criterion can relate to one or more actions of the labeling process, for example, the degree of conformity of the generated print image to a print image template and the accuracy of the alignment of the label 7 on the respective package 3. In particular, the quality criterion allows for a more detailed analysis and documentation of all the labeling processes performed in a labeling routine.In one embodiment, it is provided that, based on a predetermined calculation rule, depending on the meter information, preferably further depending on the assigned labeling process type and / or the assigned degree of fulfillment of the quality criterion, price information of a labeling routine is determined and assigned to the respective labeling process, preferably that the price information is stored for the meter information.

[0060] For example, the calculation rule contains the specified costs for a particular label type. It is also conceivable that the price information assigned to a labeling process depends on the quality criterion.

[0061] Furthermore, it is preferably provided here that the counter information is stored in a production control system of the labeling system 1 (not shown here), or that the counter information is stored in the control arrangement 4 and transmitted to the production control system, in particular with the assigned labeling process type, the assigned degree of fulfillment of the quality criterion and / or the assigned price information.

[0062] The production control system can be part of a production control system that serves to consolidate data from various labeling devices 2. The production control system is, in particular, superordinate to the control arrangements 4 of several labeling devices 2. In one embodiment, the production control system is implemented via a cloud, which has at least one cloud server.

[0063] A labeling system 1 with a labeling device 2 is proposed, wherein the labeling device 2 is configured to be controlled in a labeling routine for labeling, in particular for price labeling, individual packages 3 by means of a control arrangement 4 of the labeling device 2 in order to apply a label 7 to a respective package 3 in a labeling process, wherein the labeling device 2 has: a weighing arrangement 5 for determining weight values ​​of the respective package 3, a dispensing arrangement 6 for dispensing a label 7, a printing arrangement 9 for printing the label 7 depending on the weight values, and an application arrangement 13 for applying the label 7 dispensed by the dispensing arrangement 6 to the respective package 3.

[0064] It is essential that the labeling system 1 is configured to check the operating parameters recorded during a respective labeling process for compliance with a predefined completion criterion representing a successful labeling process and to record the occurrence of a fulfilled completion criterion in a counter information. Reference is made to all explanations of the proposed method.
