Description

The invention relates to a device for receiving tools according to the preamble of claim 1. Such a device is, for example EP1920910 known.

Both printing presses with integrated further processing devices, for example for creasing or embossing, as well as further processing machines, such as, for example, folding machines, cover feeders or folding box gluing machines, have tool units for processing the sheet-like material.

Also in the production of high-quality printed products for the packaging industry, such as folding cartons, sheets are first broad-web printed in a printing press. On the sheets are each several benefits of the carton to be printed, 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.

• 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.
• 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 stream 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.
• 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.

In addition, folding box gluing machines optionally have modules for scoring, punching and embossing, for example for embossing Braille fonts in pharmaceutical packaging.

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 is guided in a roller cheek and the upper conveyor belt in a roller rail. The conveyor belts are arranged transversely adjustable and can thus be adjusted to the respective folding 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 For example, such a folding box gluing machine is known.

Furthermore, from the EP 1 920 911 A1 a Faltschachtelklebemaschine with a module for embossing Braille.

In the known modules an adaptation of the tool to the respective sheet format to be processed or the change of tools is very expensive.

The object of the present invention is therefore to provide a device in which the tool units can be easily adapted or changed simply to the respective sheet format as well as to the respective processing to be performed.

This object is achieved by the characterizing features of claims 1 to 11.

In a preferred embodiment of the present disclosure, the apparatus for processing flat, arcuate material has right and left frame walls which are connected to each other by crossbeams. The apparatus further comprises a lower and upper tool receiving device for a lower and upper tool unit. The tool receiving devices each have right and left side walls, upper and lower cross members, and drive shafts. The lower crossbeam is attached to the frame walls and the lower drive shaft in the side walls of the lower tool receiving device. The upper cross-beam and the upper drive shaft in the side walls of the upper tool receiving device. According to the invention, the cross members have a profile which is suitable for receiving the forces arising transversely, in and perpendicular to the direction of cut during processing of the blank, for example during embossing. The forces absorbed by the crossbeams are thereby advantageously derived via the frame and side walls. This makes it possible to dimension the drive shafts 28, 29 smaller in diameter and thus to keep the moving masses low. The upper and lower tool unit are laterally adjustable via upper and lower tool guide elements sliding on the crossbeams. This makes it advantageously possible to easily position the tool on any position of the sheet and / or to position any number of tools on the drive shaft. Furthermore, occurring forces, such as stamping forces, intercepted in the crossbeam. Therefore, the drive shaft is made relatively thin, since it only has to transmit the driving forces. Furthermore, this design has the advantage that different width tools can be easily used.

In a further particularly preferred embodiment of the present disclosure, the upper tool receiving device is pivotable about a frame fixed pivot about the lower tool receiving device. As a result, a tool change is simplified on the one hand and on the other hand, a troubleshooting, for example, when double-feeding sheets, simplified.

In a further advantageous embodiment according to the present disclosure, the upper and lower tool units are fixed at any location on the crossbeams via pneumatic tensioning elements. In this way, the tool units are easy and fast to fix. As an alternative, of course, a fixation on fitting bolts and fitting groove / - bore possible.

In another embodiment according to the present disclosure, the tool units each comprise a top and bottom tool, respectively, mounted on a universal receiving cylinder. Advantageously, such different processing tools can be exchanged easily and quickly against each other.

In a particularly preferred embodiment according to the present disclosure, the lower sidewalls are secured to the frame walls with the lower operator side sidewall configured as a removable lower drive shaft bearing cap. In addition, the upper operator-side side wall has a removable bearing cap for the upper drive shaft.

This embodiment has the advantage that the side plates with storage can be easily removed. Due to the then free shaft ends, the removal and insertion of the tool holder is easily possible, resulting in short set-up times, especially when of a tool type (for example, tool for grooving, punching, embossing, cutting, perforating, milling, application of hot foil, etc .) must be changed. Furthermore, the tool units can also be equipped with tools outside the machine and then used, in particular if several pairs of tools are available.

In a particularly preferred embodiment according to the present disclosure, the upper and lower drive shafts are designed as polygonal shafts. This design offers the advantage of a particularly easy handling when changing tools. Furthermore, the shape of the drive shafts ensures that the upper tool and the lower tool always rotate with angular accuracy to each other.

To ensure that the upper tool is also rotationally aligned with the lower tool, it is useful, for example, to fix the tools by means of set screws on the polygon shaft.

In another preferred embodiment according to the present disclosure, the upper and lower drive shafts are driven by servomotors.

In another preferred embodiment according to the present disclosure, the upper and lower tool guide elements have abutment areas for the pneumatic clamping elements. This allows an easy, simple and accurate positioning and fixing of the tool units.

In a particularly preferred embodiment according to the present disclosure, the upper and lower tool units cooperate with a centering element. In this way it can be ensured in a simple manner that the tool units are moved and aligned synchronously.

In another embodiment according to the present disclosure, the distance of the upper to the lower tool unit is variable via two pneumatic cylinders. This allows the use of variable material thicknesses of the sheet material in a simple manner and also the possibility of variable embossing depths. In addition, the tool units are scalable not only with regard to the working widths but also with regard to the tool diameter. In addition, the distance via a fine adjustment is adjustable, so that the embossing depths can be set very accurately.

In another embodiment according to the present disclosure, the tool units are protected by protective boxes and the drive shafts are protected against tampering by safety devices. By this encapsulation, the device is easily secured.

FIG. 1 shows by way of example for a further processing machine a folding box gluing machine with a plurality of processing stations in which tool receiving devices according to the invention can be used.

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. The alignment station is used to guide transversely positionable machine components in the form of two belt pairs, which serve as conveyors and can be transversely positioned via actuators.

This is followed by a primary crusher 6 and a first folding module 7. The machine components in the form of belt pairs, which can be positioned transversely in the form of belt pairs, both through the primary shredder 6 and through the folding module 7, are transversely positioned 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 means.

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 means.

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 by the processing station 13 lead belt pairs as conveying elements, which 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. This is followed by a transfer station 15, from which the folded blanks, provided with not yet set adhesive seams, are exactly aligned in all parts with the subsequent collecting and pressing device 16. 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 a device according to the invention. The device comprises a right frame wall 20 and a left frame wall 21, which by transverse members 22, of which in FIG. 2 one is shown interconnected. On the frame walls 20, 21, the lower tool receiving device 3 is firmly screwed. The lower tool receiving device 3 has a lower cross-beam 24, which is screwed between the frame walls 20, 21, on. Further, a lower drive shaft 29, which is between a left lower side wall 39 and a lower right side wall, which is listed as a removable bearing cap 38 is stored. The lower left side wall 39 is mounted on the left frame wall 21 and the lower bearing cap 38 on the right frame wall 20. On the lower drive shaft 29, a lower tool unit 34 is mounted and via a lower tool guide member 41, which is supported on the lower cross-beam 24, laterally slidably connected to the lower drive shaft 29. With the aid of a pneumatic lower clamping element 32, the lower tool unit can be fixed at any point between the two lower side walls 38, 39. For this purpose, the pneumatic lower clamping element presses against the lower stop area 43 (FIG. FIG. 3 ) of the lower tool unit 34 and is supported at the same time on the lower cross-beam 24. Above the lower tool receiving device 3 is an upper Tool receiving device 2 attached. This is pivotally mounted about a frame-fixed axis of rotation 37. The upper tool receiving device 2 has an upper cross-beam 23 and an upper drive shaft 28, both of which are mounted between a left upper side wall 26 and a right upper side wall 25. The upper right side wall has a removable upper bearing cap 27 for supporting the drive shaft 28. On the upper drive shaft 28, an upper tool unit 33 is mounted and laterally slidably connected to the upper drive shaft 28 via an upper tool guide element 40, which is supported on the upper cross-beam 23. According to the invention, the cross members 23, 24 have a profile which is suitable for receiving the forces arising during processing of the blank, for example during embossing, transversely, in and perpendicular to the cutting direction. For example, the profile has at least a high resistance moment perpendicular to the direction of cutting. As a result, it is advantageously ensured that the transverse members are almost parallel to one another over the entire width. The forces absorbed by the crossbeams are thereby advantageously derived via the frame and side walls. This makes it possible to dimension the drive shafts 28, 29 smaller in diameter and thus to keep the moving masses low. By means of an upper pneumatic tensioning element 31, the upper tool unit 33 can be fixed at any point between the two upper side walls 25, 26. For this purpose, the pneumatic upper clamping element 31 presses against the upper stop area 42 of the upper tool unit 33 (FIG. FIG. 3 ) and at the same time supported on the upper cross-beam 23. The two drive shafts 28, 29 are each driven by a separate servomotor 30. As a result of this construction, the transverse members 23, 24 absorb the possibly occurring high forces, for example the embossing forces during the embossing process, and the drive shafts 28, 29 only transmit the torques. As a result, the rotating masses are kept low. The pivoting movement of the upper tool receiving device 2 about the frame-fixed axis of rotation 37 is advantageous for eliminating Doppeleinzügen and a tool change. The distance between the two tool receiving devices 2, 3 to each other can be varied via two pneumatic cylinders 35, 36. These are based on the one hand on the frame walls 20, 21 and on the other hand on the upper side walls 25, 26 from. The effect of the tool units 33, 34 on the arcuate, to be machined Material 11, 12, which is transported between the two tool units 33, 34, can be adjusted so targeted. In particular, the conversion to different thicknesses is thereby easily possible.

FIG. 3a now shows the device according to the invention in a side view. Shown is the left part of the device with the crossbeams 23, 24, which are supported on these tool guide elements 40, 41 and the tool units 33, 34. Furthermore, the already described clamping elements 31, 32 with the stop areas 42, 43 can be seen.

In FIG. 3b the device according to the invention is shown in a side view from the opposite side with fine adjustment device 60. As already described, the distance of the two tool receiving device 2, 3 and thus also the distance of the tool units 33, 34 via pneumatic cylinders 35, 36 can be adjusted by the upper tool receiving device 2 is pivoted about the frame fixed axis of rotation 37. In particular, when using embossing tools, for example for 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 invention, characterized in that the fine adjustment device 60 has two stops 58, 59 and the stopper 59 is stationary and the stop 58 via a handwheel 56, a threaded spindle 57 and unspecified worm gear to the desired distance is adjustable.

In FIG. 4 the safety device can be recognized. The safety device consists of a fender, not shown, and light barriers 44, which form a safety light grid. In this way, the tool units are secured against unauthorized contact. Furthermore, the tool units 33, 34 shown in teildemounted state, based on the FIG. 6 will be described in more detail. FIG. 5 shows the tool units 33, 34 according to the invention in the disassembled state together with the tool guide elements 40, 41.

FIG. 6 shows the tool units 33, 34 according to the invention in the disassembled state and partially dismantled. The upper tool unit 33 has a universal receiving cylinder 47, on which an upper tool 48 is attached. The upper tool unit 33 is protected by an upper protective box 45.

The lower tool unit 34 also has a universal receiving cylinder 49 with a lower tool mounted thereon. The lower tool unit 34 is protected by a protective box 46.

If a plurality of tool units 33, 34 are respectively arranged on the drive shafts 28, 29, for example a plurality of embossing devices 54, 55 for embossing braille symbols, as in FIG Fig. 10a illustrated, it may be advantageous that the tools can be aligned relative to each other on the shafts in the circumferential direction to each other both in terms of upper tool to lower tool and the tool pairs. This is possible, for example, in that the tools 48, 50 can be adjustably fastened on the universal receiving cylinders 47, 49 in the circumferential direction or that the tool units themselves are fastened rotatively relative to clamping elements.

FIG. 7 shows the device according to the invention with removed tool units 33, 34 and removed upper bearing cap 27 and lower bearing cap 38. In this state, the drive shafts 28, 29 are freely accessible and the tool units 33, 34 easily replaceable.

FIG. 8a shows the tool units 33, 34 with the centering element 51. To ensure a synchronous displacement / alignment of the two tool units 33, 34, these are coupled to each other by means of a centering element 51. The centering element is designed in such a way that the centering function is switched on and off depending on whether sheets pass through the machine or not. The centering element 51 is a centering pin mounted in the upper tool unit 33, which is lowered manually downwards into a bore in the lower tool unit 34 and thus firmly connects the upper tool and the lower tool ( Fig. 6 ).

FIG. 8b shows a device according to the invention with an indexing device 61 for the tool units 33, 34. As already described, the tool units 33, 34 are mounted on drive shafts 28, 29. These drive shafts 28, 29 can advantageously be designed as polygonal shafts, for example with a profile type which is approximated to a square in relation to its cross section. If z. B. the tool units 33, 34 are formed as embossing tools for Braille symbols, it is important that the male and female are arranged mutually fitting on the drive shafts. In a polygonal shaft with an approximately square cross section, the tools can be pushed in four different positions on the drive shaft. So that the tools are pushed in the correct position, the drive shafts each have at least one Indexierbolzen 63 and the tool units an indexing groove 62. In this way it is ensured that the tool units are pushed in the correct position.

In the FIGS. 9a and 9b the device according to the invention is shown in an embodiment for synchronous grooves with scoring tools. The carton blanks 12 are transported between the two illustrated upper creasing tools 52 and the lower creasing tools 53. The upper and lower scoring tools 52, 53 are guided by the tool guide elements 40, 41, which are respectively supported on the transverse members 23, 24 in the manner already described. The two scoring tools 52, 53 shown are only examples; Any number of scoring tools can be arranged on the drive shafts in accordance with the requirement. Also, a mixture of different tools, such as scoring tools, together with embossing tools is possible.

In the Figures 10a and 10b the device according to the invention is shown in an embodiment for synchronous embossing as a so-called Braille module. The carton blanks 12 are transported between the four illustrated upper braille embossing tools, which are designed as male members 54, and the lower braille embossing tools, which are designed as dies 55. The patrices 54 and matrices 55 are guided by the tool guide elements 40, 41, which are respectively supported on the transverse members 23, 24 in the manner already described. As can be seen, the braille tools 54, 55 can be set anywhere on the carton blank. Also, the number of braille tools 54, 55 is arbitrary.
