In the production of high-quality printed products, for example folding cartons for the pharmaceutical and cosmetics industry, high demands are placed on the quality of the printed sheets as well as the die-cut folding carton blanks up to the finished folded and glued cartons, and in addition the pharmaceutical industry places high demands on accuracy the imprints as well as the Braille impressions of the produced cartons. This already makes an error control during production during the entire production workflow, for example:

• ● Paper defects such as cardboard inclusions
• ● Foreign particles, eg dust, unwanted residues of film, punching waste, stickers and glue residues
• ● Color deviations or paint defects (missing paint, paint on unwanted surfaces, paint splashes), blurred contours
• ● Register offset
• ● Text error
• ● Errors in hot foil stamping (holes in the surface, frayed edges, missing surfaces)
• ● Scratches and mechanical defects in the sheet surface (in unprinted cardboard, in the printed image, in the paint or in the film)
• ● Matrix codes
• ● Missing windows or other applications from upstream production steps
• ● varietal purity the benefits
• ● Matching barcodes and / or Braille embossing with the legible synopsis
• ● Exactness of the braille embossings with regard to position, volume and height of the braille dots
  etc necessary.

For the production of folding cartons, the sheets are first printed wide web in a printing press. On the sheets, several benefits of the cartons to be produced are printed in each case, which are then punched out in a punch. The punched-out folding box blanks are then fed to a folding box gluing machine and processed here into folding boxes.

• Einen Einleger, der die zu verarbeitenden Zuschnitte mit hoher Geschwindigkeit aus einem Stapel nacheinander abzieht und einzeln der nachfolgenden ersten Bearbeitungsstation zuführt,
• Ein Auftragwerk für Klebstoff, üblicherweise Leim, das auf die zu verklebenden Faltlappen einen Klebstoffstreifen aufträgt und
• Eine Faltstation, in der die mit einem Klebestreifen versehenen Zuschnittteile zur Herstellung einer Klebeverbindung um 180° umgelegt, also gefaltet werden.
• Im Anschluss an die Faltstation ist üblicherweise eine sogenannte Überleitstation angeordnet, in der die Schachteln gezählt, markiert und ― falls schadhaft - ausgeschleust werden können.
• Danach folgt eine Pressstation, an deren Anfang ein Schuppenstrom aus gefalteten Zuschnitten gebildet wird, der in der Pressstation für einige Zeit unter Druck gehalten wird, damit die beiden Zuschnitte an der Klebenaht verbunden werden.

Folding box gluing machines for the production of folding boxes from folding box blanks are known to have at least the following modules as processing stations:

• A feeder, which pulls the blanks to be processed at high speed from a stack one after the other and feeds them individually to the subsequent first processing station,
• An applicator for glue, usually glue, which applies an adhesive strip to the folding flaps to be glued and
• A folding station in which the blank parts provided with an adhesive strip are folded by 180 °, ie folded, to produce an adhesive bond.
• Following the folding station usually a so-called transfer station is arranged, in which the boxes can be counted, marked and - if defective - can be discharged.
• This is followed by a pressing station, at the beginning of which a shingled flow of folded blanks is formed, which is held in the pressing station for some time under pressure, so that the two blanks are connected to the adhesive seam.

The individual processing stations have conveying means driven for transporting the folding box blanks. These consist, for example, each one arranged on the side of the machine upper and lower conveyor belt, the lower conveyor belt in a roller cheek and the upper conveyor belt are guided in a roller rail. The conveyor belts are arranged transversely adjustable and can thus on the respective carton blank format. The blanks are transported printed side down between the top and bottom conveyor belts. From the DE 10 2004 022 344 A1 Such a folding box gluing machine is known.

In the context of mass production, it makes sense to check the possible errors inline to ensure that the manufactured products meet the quality requirements.

For this purpose, it is known to perform the checks with line scan cameras, which are arranged above the sheet transport plane.

Since the blanks are transported in the Faltschachtelklebemaschine with the printed side down from the transport device through the individual processing stations, it makes sense to arrange the line scan camera below the blank transport plane. Since the camera is to take a picture of the entire printed cut width, interfere with the lower continuous conveyor elements.

From the DE 10 2005 050 040 A1 a device is known in which an inspection of a resting on a conveyor belt sheet on the back is possible. The camera is mounted in a gap of the conveyor belt below the sheet transport plane. For this purpose, the conveyor belt is placed over pulleys in a loop. A disadvantage of this solution is that the installation space for the camera is limited and the manufacturing costs for the transport device are quite high.

From the DE 10 2011 012 807 a device for the control of sheet material is known in which the control system is arranged above and / or below the transport device and consists of a camera and a light source. The camera angle with respect to the surface to be controlled and / or the angle of incidence of the rays of the light source on the arcuate material is changeable.

From the EP 2 039 513 a method and apparatus is known in which information about surface defects is collected during the machining process, the then lead to a classification of the finished substrate. Based on this classification, a decision can then be made as to whether the substrate meets the quality requirements or is discharged.

With the known methods, the control of raised structures, such as Braille embossing, is limited.

From the WO 2011/009566 A1 Now, an apparatus for analyzing the topography of a surface of a substrate is known. The device also includes a camera and a light source aligned at defined angles to the substrate. The one-dimensional image recorded by the camera is stored in a memory. By means of the known triangulation method, a three-dimensional image is generated.

From the EP 1 788 510 is also a non-contact detection and analysis of Braille impressions by means of the light-cut triangulation known. With the method described, both the position and the height of the surveys can be checked.

In the known devices defective sheets are discharged.

The object of the present invention is to provide a method and a device with which the number of faulty embossed sheets can be reduced.

This object is achieved by the characterizing features of claim 1 and according to the method steps of claim 7.

• die Prägung nachgeregelt (Höhe der Braillepunkte und / oder Position der Braillepunkte relativ zur Schachtelkante);
• die Abweichung zu den Sollwerten auf einem Bedienerdisplay angezeigt;
• oder einfach nur die Genauigkeit der IST-Werte auf einem Bedienerdisplay bestätigt;
• zusätzlich kann ein Ausschleusemodul zur Ausschleusung der fehlerhaften Schachtel betätigt werden.

In a preferred embodiment, the folding box gluing machine has at least one checking device for checking qualitative aspects during folding box production. This at least one control device is designed as an optical braille embossing control device and evaluates the Braille embossments at least in terms of position, height and volume. The Braille embossing control device is located behind a Braille embossing device within the Faltschachtelklebemaschine. The Braille embossing device has a male and female. The Braille embossing control device is connected to a control device which controls the distance between and / or the position of male and female relative to each other and / or the position of the male and female relative to the carton based on the signals supplied by the Braille embossing control device. This embodiment has the advantage that the Braille impressions can also be analyzed topographically and the results are used immediately for further production, which minimizes the number of Braille embossings out of tolerance and thus scrap. Depending on the measurement result:

• the embossing adjusted (height of the Braille points and / or position of the Braille points relative to the edge of the box);
• the deviation from the target values is displayed on an operator display;
• or just confirm the accuracy of the actual values on an operator panel;
• In addition, a discharge module for discharging the defective carton can be actuated.

In an alternative embodiment, the braille dots are sprayed or printed. In this case, the order quantity would be varied instead of the embossing gap.

In a further preferred embodiment, the folding box gluing machine has at least one further control device for two-dimensional image inspection of the folded box. This embodiment has the advantage that even two-dimensional errors, such as contamination, color deviations, register offset, type purity, etc., can be detected on the folding boxes with the known control modules, for example by means of a CCD camera.

In a further preferred embodiment, the further control device is mounted before and / or after the Braille embossing control device. In this way, visual influences of the printed image can be detected by the Braille. In a particularly preferred embodiment, the control devices are arranged below the transport device for the folding boxes. This will ensure that the front of the box is inspected, and thus both the print image and the height of the braille dots are actually captured.

In a further preferred embodiment, a plurality of control devices are arranged next to one another. This applies to both the two-dimensional and the topographic control device. This has the advantage that a study of the complete box is possible. Thus, it is possible, even several Braille stampings on the box at different positions, eg. B. side by side or offset one behind the other, to examine individually and in one step.

The Faltschachtelklebemaschine can also be used as an offline module to control, for. B. applied in the punch Braille, are used, which would then account for unnecessary processing stations. Such an offline module would then have, for example, the following stations: depositor, alignment station, control device, Braille embossing control device, ejection module.

All Faltschachtelklebemaschinen according to the embodiments include a plurality of processing stations, which are traversed by the box blanks sequentially.

FIG. 1 shows by way of example individual processing stations of a known Faltschachtelklebemaschine.

The folder gluer starts in FIG. 1 bottom right with an insert 1, which pulls off the blanks to be processed at high speed from a stack one after the other and feeds them individually to the subsequent processing station. Following the insert 1 is followed by an alignment station 4, in which the blanks are individually aligned against a lateral stop. Lead through the alignment station Transversely positionable machine components in the form of two pairs of belts, which serve as conveying elements and can be transversely positioned via actuators.

This is followed by a primary crusher 6 and a first folding module 7. Both through the primary shredder 6 and through the folding module 7, transversely positionable machine components in the form of belt pairs guide the conveyor elements, which are positioned transversely with an actuator depending on the type of blank.

On the folding module 7 follows a turning station 9. The turning station 9 includes for rotating the blanks about a vertical axis by 90 ° two parallel juxtaposed conveyor lines whose speed is adjustable separately. The blanks are on both conveyor lines, so that they are rotated at different speeds of the two conveyor lines. The two conveyor lines contain driven rollers as conveying elements.

Subsequent to the turning station 9 is followed by a further alignment station 10, which corresponds in its construction of the alignment station behind the insert 1. It thus again contains transversely positionable machine components in the form of pairs of conveyor belts as conveying elements.

The next processing station 13 serves to perform box-type dependent processing operations; For example, further score lines are pre-broken or special folds are performed. Also through the processing station 13 lead belt pairs as conveying elements that can be positioned transversely with actuators.

This is followed by a folding station 14, in which the blank parts previously provided with an adhesive seam are folded over by 180 °. The folding station 14 includes pairs of belts as conveying elements and an adhesive applicator, which can be moved by means of actuators in their dependent of the cutting type transverse position. Then follows a transfer station 15, of which the folded, provided with not yet set adhesive seam blanks in all parts exactly aligned the subsequent collection and Pressing device 16 are supplied. In the collecting and pressing device 16, a shingled stream of folded blanks is first formed, which is subsequently held under pressure for some time between conveying press belts, so that the adhesive seams set. The transfer station also contains pairs of belts, which can be transversely adjusted by means of actuators.

FIG. 2 shows by way of example a transport device 8, each with a left and right upper conveyor 3,3 'and in each case a left and right lower conveyor 2, 2', in the present example as a belt conveyor with corresponding conveyor belts as conveying means 5, 5 ', 12, 12' is trained. The conveyors 3, 3 ', 2, 2' are mounted on round trusses 11, so that they can be adjusted to the respective box cutting width.

FIG. 3 shows an inventive embodiment of a Faltschachtelklebemaschine. It comprises, by way of example, the following processing stations: an inserter 1, an alignment station 4, a two-dimensional error control control device 17, a Braille embossing device 18, followed by a Braille embossing device 19, a primary crusher 6, an erecting box station 30, a folding module 7, an ejection module 31, a transfer station 15 and a collecting and pressing device 16. The processing stations and their order is only an example. Likewise, the arrangement and number of control devices 17, 19 is merely exemplary. The control station 17 is connected to a controller 32. It supplies data on faulty boxes to this controller. The controller sends in response to these data signals to the Ausschleusestation 31 for discharging these defective boxes. In Braille stamping control device 19, the Braille embossings are examined with respect to height, area and volume, ie topographically for errors. Furthermore, the position of the Braille embossing to the box edge as well as the completeness and correctness of the embossing is analyzed. The data is then either placed on a display so that the operator can make the appropriate corrections manually, or forwarded via the controller to the appropriate station for automated adjustment or ejection.

In the following schematic illustrations, for better clarity, only one upper and one lower conveyor is shown.

FIG. 4 shows a control device 17. The sheet material to be checked 24, such as folding box blanks, is transported by means of a transport device 20 in the conveying direction 25 through the device 17. In the embodiment shown, the transport device 20 has an upper conveyor 21 with an endless conveyor 23, which is guided around deflection rollers 26. Furthermore, two lower conveyors 22, 22 ', which form a gap to each other. Both lower conveyors 22, 22 'also have conveying means 23, which are guided around deflection rollers 26. The, as seen in the conveying direction 25, the second pulley, as seen in the conveying direction 25, first lower conveyor 22 is connected to a drive, not shown, and thus serves as a drive roller 27 for the conveyor 23 of the lower conveyor. The conveying means 23 in the present embodiment are designed as endless conveyor belts. The conveying means 23 of the upper and lower conveyors 21, 22, 22 'touch each other and clamp the sheets 24 to be transported between them. The upper conveyor is mounted in a known manner in a roller rail 29 and the lower conveyor means in roller cheeks 28. Below the sheet transport path, a control system 72 is mounted within the gap between the lower conveyors 22, 22 'such that the sheets transported across the gap can be tested from below by means of the control system 72. The control system 72 has a camera and a light source. For better clarity, camera and light source are shown only schematically. They serve to detect two-dimensional defects on the carton.

Of course, the control system 72 according to the invention can also be formed with other transport devices 20 to form an inspection module.

FIG. 5 shows a Braille embossing control device 19. The structure is equal to the structure of the control device 17 in the present embodiment FIG. 4 , The difference is the use of a 3D sensor 73 for topographical error control.

• ● Höhe, Fläche und Volumen der einzelnen Braillepunkte
• ● Position der Brailleprägung relativ zur Schachtelkante
• ● Prüfung, ob alle Punkte der Prägung vorhanden sind und ob die richtige Prägung verwendet wurde

The 3D sensor 73 provides the following signals:

• ● Height, area and volume of the individual Braille points
• ● Braille embossing position relative to the box edge
• ● Check if all the points of the embossing are present and if the correct embossing has been used

• — die Brailleprägevorrichtung 18 nachregeln, falls die Höhe oder das Volumen der einzelnen Braillprägepunkte außerhalb des Toleranzbereiches liegt, und zusätzlich ein Signal an das Ausschleusemodul 31 zur Ausschleusung der fehlerhaften Schachtel senden.
• — die Ausrichtestation und / oder das Prägewerkzeug nachregeln, falls die Position der Brailleprägepunkte relativ zur Schachtelkante außerhalb des Toleranzbereiches liegt, und zusätzlich ein Signal an das Ausschleusemodul 31 zur Ausschleusung der fehlerhaften Schachtel senden.
• — Eine Fehlermeldung an das Bedienerdisplay senden, falls die falsche Brailleprägung verwendet wird oder einzelne Braillepunkte Fehler und zusätzlich ein Signal an das Ausschleusemodul 31 zur Ausschleusung der fehlerhaften Schachtel senden.

The data is sent to a controller 32. Depending on this data, controller 32 will:

• - readjust the braille embossing device 18 if the height or the volume of the individual braille embossing points is outside the tolerance range, and in addition send a signal to the discharge module 31 for discharging the defective carton.
• - readjust the alignment station and / or the embossing tool, if the position of the Braille embossing points relative to the box edge is out of tolerance, and in addition send a signal to the discharge module 31 for discharging the defective box.
• - Send an error message to the operator display if the wrong Braille stamping is used or if individual Braille dots send errors and additionally a signal to the reject module 31 for ejecting the defective box.

Of course, the described processes can all be done manually by the operator. In this case, the controller 32 would send corresponding instructions to the operator display.

FIG. 6 shows by way of example a Braille embossing device 18. The device 18 has a right frame wall 40 and a left frame wall 41, which by transverse members 42, of which in FIG. 6 one is shown interconnected. On the frame walls 40, 41, the lower tool receiving device 33 is firmly screwed. The lower tool receiving device 33 has a lower crossbar 44, which is bolted between the frame walls 40, 41, on. Further, a lower drive shaft 49, between a left lower side wall 59 and a lower right side wall, as Removable bearing cap 58 is listed, is stored. The lower left side wall 59 is mounted on the left frame wall 41 and the lower bearing cap 58 on the right frame wall 40. On the lower drive shaft 49, a lower tool unit 54 is mounted and via a lower tool guide member 61, which is supported on the lower crossbar 44, laterally slidably connected to the lower drive shaft 49. With the aid of a pneumatic lower clamping element 52, the lower tool unit can be fixed at any point between the two lower side walls 58, 59. Above the lower tool receiving device 33 is an upper

Tool receiving device 34 attached. This is pivotally mounted about a frame-fixed axis of rotation 57. The upper tool receiving device 34 has an upper crosspiece 43 and an upper drive shaft 48, both of which are mounted between a left upper side wall 46 and a right upper side wall 45. The right upper side wall has a removable upper bearing cap 47 for supporting the drive shaft 48. On the upper drive shaft 48, an upper tool unit 53 is mounted and laterally slidably connected to the upper drive shaft 48 via an upper Werkzeugfiihrungselement 60, which is supported on the upper cross member 43. With the aid of an upper pneumatic tensioning element 51, the upper tool unit 53 can be fixed at any point between the two upper side walls 45, 46. The two drive shafts 48, 29 are each driven by a separate servo motor 50. The pivoting movement of the upper tool receiving device 34 about the frame-fixed axis of rotation 57 is advantageous for eliminating Doppeleinzügen and a tool change. The distance between the two tool receiving devices 33, 34 to each other can be varied via two pneumatic cylinders 55, 56. These are based on the one hand on the frame walls 40, 41 and on the other hand on the upper side walls 45, 46 from. The effect of the tool units 53, 34 on the arcuate material 24 to be processed, which is transported between the two tool units 53, 34, can thus be adjusted in a targeted manner. In particular, the conversion to different thicknesses is thereby easily possible. The pneumatic cylinders 55, 56 are connected to a controller 32 which controls the pneumatic cylinders 55, 56 in response to the signals of the Braille embossing control device 19.

FIG. 7 is the device 18 in a side view with an additional fine adjustment device 62. As already described, the distance between the two tool receiving device 33, 34 and thus the distance of the Braille stamping tools 64, 65 via pneumatic cylinders 55, 56 can be adjusted by the upper tool receiving device 34th is pivoted about the frame-fixed axis of rotation 57. When embossing braille symbols in folding boxes, it is advantageous if an additional fine adjustment of the distance of the embossing tools to each other is possible. This makes it possible, on the one hand, to adjust the embossing tools more precisely to the thickness of the carton, but on the other hand, the embossing depth into the carton and thus the clean formation of the braille symbols can be positively influenced. Desirable here is a setting up to the 100ths of a millimeter range. This fine adjustment is realized in the present embodiment, characterized in that the fine adjustment device 62 has two stops 68, 69 and the stop 69 is stationary and the stop 68 via an adjusting motor 70, a threaded spindle 67 and unspecified worm gear to the desired distance is adjustable. The adjusting motor 70 is here, as well as the pneumatic cylinder 55, 56, connected to a controller 32 which controls the pneumatic cylinder 44, 46 and the adjusting motor 70 in response to the signals of the Braille imprint control device. In the present embodiments, the pneumatic cylinders 55, 56 and the threaded spindle 67 are merely exemplary embodiments. There are also other actuators that can be controlled by the controller 32, conceivable. In addition, the Braille embossing device may have an adjusting device, not shown, for the male and female. This makes it possible, via the controller 32 to adjust the braille tools relative to the blank, if the Braille embossing is outside the tolerance with respect to their distance from the box edge.

Furthermore, it is also possible to replace the adjusting motor 70 by a mechanical adjustment, which is adjusted by the operator. In this case, the controller would send the data to a display. Depending on this data, the operator could then make any necessary adjustment.
