Description

The present invention relates generally to the field of processing articles of sheetlike elements, such as paper and / or cardboard, in particular corrugated board, for the manufacture of boxes and cartons for the packaging of packaged goods. When processing z. B. corrugated cardboard boxes are on the one hand various steps or procedures and on the other hand different machines and devices for mechanical processing by deformation without material removal necessary. The devices are therefore equipped with various tools for scoring, cutting, perforating and scoring.

The present invention relates to such a processing device for the grooves, cutting, perforating and scoring of flat elements, in particular of cardboard, cardboard, plastic or composite materials, according to the preamble of claim 1 and a method according to claim 13.

For example, paperboard processing machines are used in the EP 1 738 883 B1 , of the EP 2 193 893 A1 and the EP 2 566 688 B1 disclosed. These machines are equipped with feed means for the corrugated cardboard or web-shaped materials in a longitudinal direction and with a plurality of cross-translating means and comprise one or more serially arranged creasing, cutting and perforating tools, wherein such tool unit or processing device through the Quertranslationsmittel can be positioned laterally. Such a classic machine is also from the DE 10 2006 050 646 A1 seen.

Machines of this type are mainly used for the processing of web-like materials use, for example, known from an endless cardboard web or, cut into individual sheets and stacked carton blanks, which z. B. in the packaging industry for the production of foldable cartons use. Several processing methods are required for the production of a foldable package, such. As the grooves, cutting and perforating. To produce corrugated or solid board products, slits and grooves are made in the board and slits are cut into the board while slitting, while the corrugation causes local compression of the corrugated board. Along the creasing lines, which usually represent a straight line, the cardboard is later angled to produce for example a cardboard from the flat cardboard. The production of cardboard is similar to papermaking. High-quality cardboard usually consists of at least three layers, whereby the outer layers are optimized for strength and the inner layer for volume.

In conventional machines of this type, the material is supplied to the individual processing stations via, for example, a conveyor belt. The processing stations are arranged one behind the other in the conveyor belt direction and are each responsible for one or at most two of the above-mentioned processing steps. The number of processing stations must therefore be reduced. From the aforementioned publications of EP 1 738 883 B1 , of the EP 2 193 893 A1 and the EP 2 566 688 B1 is z. B. it can be seen that the processing stations for the grooves, cutting, perforation have been brought together in a processing device in which the individual tools are arranged at a certain distance one behind the other.

A further development of the processing devices, in which a creasing and cutting tool are brought together in a cutting and creasing arrangement, is the EP 1 853 410 B1 and the EP 2 344 327 B1 refer to. In both processing devices, the scoring tool and the cutting tool have been integrated with each other such that the cutting tool is interposed between a pair of rotatable scoring wheel halves. In the EP 1 853 410 B1 The arranged between the Rillradhälften cutting tool by means of two pneumatic cylinders via a control linear, from a rest position to a working position and back, moved. To accommodate the cutting tool in the interior of the scoring tool, it is necessary that the Rillradhälften are mounted annularly and rotatably. This is only possible by the use of three rotatable rollers, which in turn lead via a pneumatic cylinder, the annular Rillradhälften. This embodiment of the processing device is technically very complicated, thus costly and above all only the work steps or working procedures, the grooves, cutting, and possibly perform perforation. The adjustment of the cutting tool in the Rillrad- and Schneidradanordnung according to the EP 2 344 327 B1 takes place according to another principle. The arranged between the creasing halves cutting tool is not linearly moved from a rest position to a working position and back, with the help of two pneumatic cylinders, but the tool change takes place via a change in the contact pressure of the creasing tool on the workpiece. At first working pressure, the scoring tool forms a groove in a bow or strip with its crown. If the working pressure is increased, the crown deforms or shifts, thereby releasing the cutting edge of the cutting tool. This processing device can only work two ways, the grooves and the cutting, run and still has another disadvantage. The disadvantage is that the contact pressure can not respond to the different types of shaft types and shaft combinations in the corrugated board. That is, the most common single-wave wave types are the C wave, the B wave, and the E wave, just to name a few. Then there is the double-wave range, where different wave combinations are used. This shows in an impressive way the variety of possibilities and thus the different required contact pressures. The simple design of the corrugated board consists of an outer ceiling, an inner ceiling and, arranged between the outer and inner ceiling, corrugated intermediate layer.

The in the DE 10 2012 220 233 A1 The disclosed processing device is a further development of the processing device from the EP 1 853 410 B1 and is considered to be the closest prior art. The difference is that the processing device from the DE 10 2012 220 233 A1 three operations that can perform grooves, cutting and perforating. This is made possible because the scoring tool consisting of two annular scarf wheel halves has in the middle a tool receiver which carries a cutting tool and a perforating tool. Due to the rotation of the tool holder, the cutting tool or the perforating tool can be pivoted into the working plane.

Furthermore, it is known that in the packaging industry in the production of cartons and boxes in grooving machines instead of creasing wheels, for generating creasing lines, thin strips of metal are used as a creasing tool. Creasing is a process in which a linear mass displacement with pusher dies occurs to provide a bendability for the material, particularly corrugated board. Such a spinning tool or scoring tool can be designed rotationally symmetrically as a scoring wheel or as an elongate component or as a skid.

Such an elongate tool, a scoring tool, is used for example in the DE 10 2013 223 854 A1 disclosed. A crease line is not produced at the same time over its entire length by pressing, but rather arises from the feed movement of the material, in particular corrugated board. Therefore, such an elongate tool has a wedge-like insertion bevel, see above all 7 and 8th , which facilitates the introduction of corrugated cardboard under the scoring tool. However, this scoring tool is not suitable for receiving a cutting tool and / or perforating tool.

Another elongated scoring tool shows the DE 20 2010 005 748 U1 on. The scoring tool has a, a line-shaped creasing edge having base body, wherein the creasing edge lifts on one end face or on both end sides. This increase can be formed by an angle or radius. Also, this scoring tool is not suitable to receive a cutting tool and / or perforating.

Based on this prior art, it is the object of the present invention to avoid the aforementioned disadvantages and to provide a processing device which reduces the width of the enclosed space of a processing device. On the one hand, it should be cost-effective to manufacture and, on the other hand, it should reduce the number of tools in a processing device, while nevertheless increasing the number of process steps. Due to the reduction in the number of tools and the set-up time is reduced. Furthermore, it makes sense to increase the processing speed of the continuous sheets and / or carton blanks in order to reduce the unit costs. A further object is to make the processing device integrable in machines for automatic paperboard processing. Machines that are equipped with such a processing device should enable a process, especially for smaller batches, for the demand-driven production of tailor-made packaging materials through a fully automatic carton blank.

To solve the above tasks, it is necessary to make a system change of rotating creasing wheels or Rillradhälften back to the skip technology.

According to the invention, the solution consists of a processing device for grooving, cutting, perforating and scribing flat elements, which consist in particular of cardboard, cardboard, plastic or composite materials. Such a processing device should comprise only one scoring tool and only one cutting tool and still provide several process steps for the mechanical processing of, for example, corrugated board.

The scoring tool is therefore advantageously connected via a corresponding lever mechanism with a pneumatic or hydropneumatic adjusting element and the cutting tool advantageously via a corresponding lever mechanism with an electric or pneumatic adjusting element. The adjusting elements are arranged in a support frame of the processing device. The support frame has for integration in a machine, preferably in a machine for machining of sheets and / or carton blanks, at least one, but preferably two linear guides. The linear guides advantageously enable a translational movement of the processing device transversely to the transport direction of the flat elements. The translational transverse movement takes place with the aid of corresponding drive means, which are usually. in a machine for processing flat elements, in particular of corrugated board for cartons, are arranged. From the prior art discloses the DE 10 2011 107 527 A1 a tool receiving device in which the tool units can be moved on a respective transverse drive shaft by a tool guide element. The pneumatic drive means for the translational transverse movement of the tool units are arranged on the side walls of the carton and / or box cutting station. A transverse displacement of the processing device according to the invention is carried out by means of a drive means and on the basis of the support frame arranged linear guides. The linear guides comprise one or more crossbeams arranged in a paperboard machine. Advantageously, the drive means for a translational transverse movement is already integrated in the support frame of the processing device according to the invention.

The technical solution of the tasks results in a processing device for grooving, cutting, perforating and scoring of sheet-like elements, in particular of cardboard, cardboard, plastic or composite materials, wherein the processing device comprises a scoring tool and a cutting tool and the scoring tool via a corresponding lever mechanism with a pneumatic or hydropneumatic adjusting element and the cutting tool is connected via a corresponding lever mechanism with an electric or pneumatic adjusting element and wherein the adjusting elements are arranged in a support frame having guides to a translational movement T1 of the processing device transverse to the translational movement T2 of the planar elements, by means of corresponding Drive means to perform in a machine for processing planar elements. The scoring tool consists of an elongate member which forms a skid which has a creasing or scoring surface on its side facing the workpiece, and wherein the skid has a slot passing through from the top to the bottom, in the longitudinal direction of the skid and is arranged to extend in the translatory direction T2 of the flat elements and which is closed at its two longitudinal ends, wherein the slot of the recording of a rotary tool for scoring, cutting, perforating and scratches is used.

In another advantageous embodiment, the elongated component is designed at least in two parts. The elongated component has, in the longitudinal direction, that is to say the direction of translation T2, two halves which form a skid. The two halves are spaced apart by spacer means and fixedly or detachably connected to each other via fastening means. The slot formed by the spacer means serves to receive a cutting tool. The distance between the skid halves corresponds to the slot width of a longitudinally closed slot of a skid according to claim 1. The distance between two skid halves can also be smaller or larger. If the distance between two skid halves is less, at least one skid half is to be provided with a recess which can accommodate a cutting tool, at least in part or even completely. This recess can be arranged either in the right or left skate half, preferably in both skid halves, and has approximately the length of the slot of the one-piece skid, according to claim 1, on.

However, the technical solution of the tasks also provides a method for the production of creasing, cutting, perforation and scoring lines according to claims 13 to 17.

Preferred embodiments and further developments emerge from the subclaims. The advantages and features will become apparent from the general description of the invention and the description of the embodiments and the accompanying drawings.

The invention is therefore based on the idea of creating a cost-effective processing device, in particular for the mechanical processing of corrugated cardboard, which can be brought into engagement at least one scoring tool, which in one processing point with the planar element, hereinafter referred to as workpiece, and at least one further processing tool which is arranged with respect to the processing device within a scoring tool. For this purpose, it is according to the invention required that the processing device in the processing point, advantageously several working methods, such as grooves, cutting, perforating and scratches, can perform. From the prior art of EP 2 344 327 B1 It is known that a processing apparatus can perform two processing methods by means of two tools, grooves and cutting in one processing point. Furthermore, from the EP 1 853 410 B1 Known that with appropriate tools, the grooves, cutting and perforating in a processing point is possible. The DE 10 2012 220 233 A1 discloses, however, that a processing device three Machining process that can perform creasing, cutting and perforating in one machining point using three tools. With the present invention of a processing apparatus, four processing methods in one processing point, the grooving, cutting, perforating and scoring are now possible. However, this is not made possible by the addition of another tool, but due to the advantageous construction and the adjusting elements used, only two tools are necessary according to the invention. In order to achieve this technical implementation, the above-mentioned objects have been achieved.

In order to enable the solution of the further task to create a smaller space for a processing device, it is according to the invention necessary to reduce the number of tools in a processing device. On the one hand manages the reduction of the enclosed space only when the large rotating Rillradhälften and their complicated storage, such. B. from the DE 10 2012 220 233 A1 known, omitted and on the other hand narrower elements or narrower tools and drives are used. Especially the width of an enclosed space for a processing device is of particular importance. The wider a processing device equipped with tools and drives, the greater the distance between two processing devices arranged side by side on a cross-beam. Due to the size or the width of such a device constellation, of course, the distance between two lines to be produced, for. As creasing, cutting, perforation and scribe lines, specified and thus fixed. But if a smaller distance between two lines is required, currently two or more successively arranged processing devices, as shown in DE 10 2006 050 646 A1 and the DE 197 54 799 A1 known in cardboard machines, which point in the transport direction of the sheet-like elements used. Due to the arrangement of processing devices arranged one behind the other on a plurality of crossbeams, the paperboard machines extend substantially and thus cause increased acquisition costs.

However, in order to reduce the width of a processing device and thus to obtain smaller distances between the lines to be produced, an elongated component, in the form of an elongate skid, is advantageously used instead of a rotating scoring tool or rotating scoring wheel shafts. The skid has a drive which is articulated in the vertical direction via a lever mechanism on the skate, thus substantially reducing the width of a processing device. The skid is used to create creasing lines, wherein the skid performs a linear material displacement. For this purpose, the skid on its, the workpiece-facing side, a creasing edge or scoring surface, which has a through-going from the top to the bottom of the skid slot. The slot is arranged running in the longitudinal direction of the skid and in the transport direction of the flat elements and closed at its two longitudinal ends. Furthermore, the slot forms a narrow elongated opening, which according to the invention is not formed over the entire length of the skid, but only in its center region. D. h., The arranged in the skid inventive slot is closed longitudinally front and rear. The slot length in a skid is approximately one-sixth to one-half the total length, preferably the slot length is approximately in the range of one quarter of the total length. The advantage of a limited in length and closed slot is clear and can be technically justified. From the prior art, for. B. the DE 10 2012 220 233 A1 , it can be seen that the incoming against the Rillradhälften sheets and / or cardboard produce in principle two creasing lines and between the creasing lines a ridge remains in the width of a cutting tool. This disadvantage is avoided by the use of a skid.

Another disadvantage of the known from the prior art creasing wheels / Rillradhälften is that their radii only have a size of 50 mm to 150 mm. Due to such small radii is formed at the leading edge between the Schneidwerkzeig and, consisting of cardboard cardboard, a large force. The large force results from the large angle of attack at the leading edge between the cutting tool and the cardboard material, whereby damage or tearing of a grooving can occur at the leading edge. To avoid this disadvantage, the skid has a radius in the longitudinal direction, which is at least 250 mm. Only with a skid it is possible to map even a very large radius, or are such large radii possible because the skid represents only a small circle section of a circle diameter. The angle of employment at the inlet edge for scoring is thus advantageously reduced substantially with the skid according to the invention, whereby the acting force on the material is reduced. Implementing such large radii via closed creasing wheels / circled halves would require an unreasonable space and be too expensive.

The incoming against a skid sheets and / or cardboard meet only on a closed surface on the skid, creating a full width score line. Only in the further course meet the incoming bows and / or cardboard on the slot in the skid, wherein the skid further produces a material displacement. The slot width in the scoring tool or in the skid is adapted to the tool width of a rotating cutting tool and can be between 1 mm and 6 mm. Basically, a slot serves to receive a rotating tool. The rotating tool is advantageously designed as a special cutting tool, which can perform three operations or three processing methods cutting, perforating, and scribing in sheets and / or cardboard, in particular in the material of corrugated cardboard. Since the individual cutting, perforating and scoring tools are now combined in one tool, this is referred to below as a multifunction tool.

The skid is not an embossing die which impresses grooves in stationary carton blanks or in resting sheets and also not around a rotating scoring wheel or rotating scarf wheel halves, but according to the invention by a skid vertically adjustable to the surface of the workpieces to be machined, on which the sheet-like elements in particular as a sheet and / or carton blank, due to a horizontal translational feed movement, are guided along. The translatory feed movement of the sheets and / or carton blanks can be done for example by a counter-roller, which is arranged below the skid. Due to this advantageous construction of the skid and the multi-function tool, the space of the processing device, especially in width can be kept very narrow and constructively much narrower compared to the known processing devices.

For adjusting a, arranged in a processing device scoring tool in the form of a skid, z. B. from the rest position to the machining position and back, is a first lever mechanism I available. The lever mechanism I has the advantage that it is arranged vertically to the scoring tool of the skid, resulting in a slim design, especially in width, results for the processing device. The lever mechanism I is formed of two levers I, II and a rocker I, wherein on the rocker I a skid is arranged. The rocker I is arranged at one end via a hinge I on the support frame. The two levers I, II make the connection of the rocker I to the pneumatic adjusting element, wherein the lever I, the connection between the rocker I and the pneumatic adjusting element and the lever II ensures the connection between the pneumatic adjusting element and the support frame. Both levers I, II, the lever I and the lever II of the lever mechanism I form with the pneumatic adjusting a common pivot point in the hinge III, wherein the lever II an additional pivot point as a rotary joint IV in the support member and the lever I an additional pivot point as a hinge V in the swingarm I has.

Due to the technical design of the processing device, the pneumatic adjusting element as a linear drive means, as described above, not directly to the rocker I and thus not directly connected to the scoring tool, the skid. The connection between the pneumatic adjusting element and the rocker I via the levers I and II. This technical embodiment has been selected according to the invention to fix the skid on the one hand in a rest and tool change position and on the other hand to hold in a machining position. In the rest and tool change position, the slide arranged on the rocker I is above and spaced from the machining position in a fixed position. The fixing of the rocker I is carried out by the embodiment and arrangement of the levers I and II. Next, the advantageous arrangement of the pneumatic adjusting element and the lever I and II with the rocker I must be considered. The pneumatic adjusting element itself has two hinges III, VI, which lie on a common axis, wherein the one rotary joint VI above and the other rotary joint III is arranged below the pneumatic adjusting element. The pivot joint III arranged below is at the same time the rotary joint for the levers I and II, whereby the three components thus have a common pivot joint III. If the piston rod is extended or retracted, the location of the rotary joint III shifts alternately on a small circular path to the processing position and away from it. When shifting the location of the rotary joint III, both levers I, II are moved. Both levers I, II form in the rest position of the tools between their legs in the hinge III an angle α, which is approximately 30 degrees, ie both levers I, II are relatively close to each other. The path of displacement of the rotary joint III is determined by the length of the lever arm and the lever II. Since the lever arm of the lever II is relatively short in relation to the length of the lever arm of the lever I, the displacement of the rocker I is also relatively low. Is the piston rod I retracted and the rocker I thus in the rest or tool change position, the lever II, because of its second pivot joint IV in the support frame, almost perpendicular to the axis of the piston rod I. In this rest position are the three hinges III, IV, VI of the pneumatic adjusting element and the lever II approximately on a common axis. The force of the pneumatic adjusting element is now on the common pivot joint III and the pivot joint IV of the lever II to the Carrier frame derived or forms the support frame, the counterforce. If the piston rod I extends to the machining position "grooves", the almost vertical lever II pivots about the pivot joint IV in an approximately horizontal position, wherein the location of the rotary joint III shifts in the direction of the machining position. Thus, the rotary joint III is no longer on the common axis of the three hinges III, IV, VI. Due to the fact that the lever I is arranged on the hinge III, at the same time the rocker I and thus the skid shifts in the direction of the machining position. If the machining position is reached, now is the pivot V of the lever I, which is arranged on the rocker I, on a common axis with the hinges III and VI. Both levers I, II form in the machining position of the tools between their legs in the hinge III an angle α, which is now about 90 degrees, which illustrates the pivoting of the lever I, II by the displacement of the piston rod I. The force of the pneumatic adjusting element is now transferred to the rocker I and no longer on the support frame. The printing process on the skid is carried out quickly and powerfully. Due to the long lever I, a small compressive force is generated on the skid and thus on the material with a small stroke of the lever II. The advantageous embodiment of the lever I, II with the pneumatic adjusting increases on the last millimeters of the skid the power transmission to the cardboard material. D. h., The more the pivot joint V of the common axis III, VI approaches, the more the pressure on the longitudinal tool of the skid, which has a rubberized roller as an abutment. The lever II now acts only as a pivot and guide lever. The second pivot joint IV of the pivoting and guiding lever II, which is arranged on the support frame, is now outside the common axis of the piston rod I and the common pivot joint III. The pneumatic adjusting element can pivot the rocker I from the rest position only to a fixed point in the direction of the machining position. This defined point determines the maximum path of the rocker I and is determined by a fixed lever, which is located on the rocker I. The fixed lever comes to a stop which is arranged on the support frame, for concern when the second rocker II with the cutting tool in the processing position, for. B. cutting, drives. If the skid again moved from the processing position to the rest and tool change position, the fixed lever detaches from the stop of the support frame and then has a certain angular distance to this.

Preferably, the pneumatic adjusting element is a gas spring, with the aid of the skid is vertically adjustable. But there are also other adjustment conceivable and usable. Due to the linear movement of the piston rod of the gas spring, the adjustment takes place in two directions. By the retraction and extension of the piston rod, the skid is moved towards the counter roll or away from the counter roll.

For adjusting a, arranged in a processing device cutting tool in the form of a multi-function tool, for. B. from the rest position to the processing position and back, is a second lever mechanism II available. The lever mechanism II has the advantage that it can be arranged vertically to the multi-function tool, resulting in a slim design, especially in width, results for the processing device. The lever mechanism is formed from a rocker II and an electrical adjustment, wherein on the rocker II a cutting tool in the form of a multi-function tool is arranged and the rocker II is attached at one end via a rotary joint on the support frame and at the opposite end via a hinge connected to the electrical adjusting element. Preferably, the electrical adjusting element is a linear motor, with the aid of which the multi-function tool is vertically adjustable. But there are also other adjustment used, for example, a pneumatic or hydraulic adjustment, with other adjustment are conceivable. Due to the linear movement of the rotor of the linear motor, the adjustment takes place in two directions. By extending and retracting the rotor, the multifunction tool is moved towards the backing roll or away from the backing roll. The linear motor is used here as a drive and positioning system because it can translate and position the multifunctional tool precisely in the vertical direction. The positioning accuracy of the positioning system depends on the drive used, in this case the linear motor, and the precision of the guides used. The linear motor acts as a direct drive and, due to its incremental position measuring system, is able to fulfill the required positioning accuracy of the cutting tool in tenths of a mm range. The guides consist of a swingarm, which is equipped with high-precision swivel joints. With this drive and positioning system, the required accuracy in the processing of sheets and / or cardboard, especially corrugated cardboard, can be achieved.

The component of the rocker I, which can be moved back and forth in a certain angular range by a pneumatic adjusting element on a circular path, has in the longitudinal direction and to the arranged in the rear area pivot joint I, opposite in the front region to the pivot joint I driver on. The driver is arranged vertically to the longitudinal axis of the rocker I and has at its free end a right angle arranged hook. The hook holds over the rocker II, whereby the rocker I of the rocker II automatically moves the scoring tool when moving the cutting tool into the rest position or rest position.

In principle, the driven by the linear motor rocker II, on which the cutting tool or the multi-functional tool is arranged on a large circular path alternately, ie clockwise and counterclockwise in a predetermined range, moved back and forth and thus also the cutting tool, which is attached to the rocker II. The runner of the linear motor moves with rectilinear motion the rocker II on a slightly curved path, which represents the stroke of the cutting tool. Due to the relatively short stroke, the path on the radius of the circular path can be neglected. The position of the multifunction tool along the stroke is precisely defined and controllable by the use of a linear motor. A multi-function tool can therefore immerse in the incoming between the skid and the backing roll cardboard material (workpiece) tenth mm exactly. In the rest position of the processing device is the rocker I with the scoring tool disposed thereon and the rocker II with the cutting tool disposed thereon in the upper end position. In the upper end position of the wings I, II, the continuous material of the sheets and / or cardboard is not processed because the scoring tool and the cutting tool are not in contact with it. Furthermore, in the upper end position of the rest position, the cutting tool or the multifunction tool is located in the slot of the skid, but the cutting tool does not completely reach through the slot. The cutting tool is still within the skid and does not protrude from the creasing edge. Advantageously, the rest position of the tools can be mechanically locked in order to avoid injuries when simply changing the tools and to improve the handling. After unlocking the wings I, II, the processing device is ready for use and can be used to produce creasing, cutting, perforating and scribe lines. Since the production of the four different lines according to the invention with only two tools and should be done at the same processing point, the electrical adjustment is equipped with a position converter. With the help of the position converter, the electrical adjustment can be used as an oscillator, whereby the cutting tool can perform a vertical oscillating movement. Due to the oscillating movement of the cutting tool, a perforation line is produced. The oscillation operation of an electrical adjustment element can be switched on and off. When switched off, the production of cutting and scoring lines is generated. In the connected state, the production of perforation lines, which is made possible by the electric adjusting element, which then acts as a drive unit for generating an oscillating movement for a cutting tool. The oscillating displacement of the rotor results in a fast feed of the cutting tool. The oscillating stroke is limited only by the used and thus available spindle length of the rotor. With sufficient runner length, any thickness of material between a cutting tool and a backing roll can be cut and perforated. Furthermore, due to a variable frequency through the converter, a variable vibration excitation on the electrical adjustment made. The variable vibration excitation therefore advantageously allows the cutting tool to produce perforation holes of different lengths and / or distances of different lengths between the perforation holes. Due to the adjustable length of the holes and the length of the spacing of the holes to each other, can be responded to any requirement for different specifications advantageously to produce an optimal perforation line to allow easy bendability of the sheets and / or cardboard. For example, on the type of perforation line, on different materials and different material thicknesses, etc., and thus on the amount, shape and size of the cuts that are desired or required due to the different requirements of packaging technology. Further consideration may be given, for example, in a demolition perforation, a break perforation or to allow a good tearing (predetermined breaking point) on a finished package along a perforation line. Also, the need for kinking or to convert transport conditions of cardboard, especially corrugated board, can be considered. From the prior art, for example the EP 0 291 972 A2 Disc-shaped perforating tools with teeth arranged on the circumference of the disc are known. Such a perforating tool is set in rotation by the transport movement of the flat elements, in particular of corrugated cardboard, whereby perforated lines are formed, which completely cut through the corrugated cardboard. The disadvantage of such perforating tools is clear. With such perforation tools, only one kind of cuts and only a distance of cuts in the material can be created, because the distance of the teeth is fixed on the circumference of a circular disc. A variation of the number of teeth and a variation of the distances of the teeth to each other are not possible. Stand for the different requirements on perforation lines Therefore, different perforation tools available, but always require a tool change. This disadvantage is achieved by the oscillating arrangement of the cutting tool in the inventive processing device for producing different sizes of cuts and different distances between the cuts. The cutting tool is therefore equipped with a toothing. The toothing has a relatively fine toothing and cutting geometry. As a fine toothing here is a relatively small pitch with relatively small tooth size and a cutting geometry, which has a relatively large number of teeth, based on a circumference and a tooth shape, which is in particular designed as a triangular tooth.

For the production of longitudinal and possibly also transverse processing lines such as creasing, cutting, perforating and scoring lines in flat elements, in particular corrugated board, different processing stages I, II, III, IV are provided. These processing stages I, II, III, IV shall be explained by processing methods described below using a processing apparatus according to any one of claims 1 to 11. To carry out a machining method, the machining device has a cutting tool which is arranged in a slot of a skid, wherein the skid are translationally adjustable by means of a pneumatic adjusting element and the cutting tool with the aid of an electrical adjusting element in a common processing point.

Advantageously, all machining processes of the processing stages I, II, III, IV are carried out with the same inventive processing apparatus and the same inventive processing tools for the production of creasing, cutting, perforating and scoring lines. The process steps are inventively very variable. Each processing stage grooves I, cutting II, perforate III, scratches IV, can be started from the rest position of the tools or from another processing stage I, II, III, IV out. Starting from the rest position of the tools results in the following method steps for the grooves, the cutting, the perforating and the scribing:
To produce a crease line with the processing device according to the invention, according to the first processing stage I with a creasing tool, the following process steps from the rest position of the tools necessary: Control of the pneumatic and electrical adjusting elements, whereby a creasing tool, consisting here of a skid, in a processing position and simultaneously a cutting tool moves to a pre-position. A pre-position is understood to mean a position that lies immediately before the processing position. The cutting tool does not protrude outwardly of the skid while the skid provides local compression by linear displacement of a paperboard, particularly a corrugated paperboard or the various layers of corrugated paperboard, passing between the skid and a backing roll to form a groove.

The preparation of a cutting line with the processing device according to the invention, according to the second processing stage II, with a cutting tool, the following steps from the rest position of the tools are necessary: control of the pneumatic and electrical adjusting elements, wherein a skid from the rest position to a processing position and at the same time Cutting tool moves from its rest position to a machining position, this releases the rocker II of the cutting tool from the driver, which is arranged on the rocker I of the skid and the cutting tool dives into the workpiece, whereby a complete cutting through a cardboard, in particular a corrugated cardboard or different layers of corrugated cardboard, takes place, whereby a cutting line is formed. The cutting tool produces a cutting line which basically cuts through all layers, for example, in the case of a corrugated board in the single-waved region, the outer cover, the shaft and the inner cover, ie two outer layers and the intermediate layer.

To produce a perforation line with the processing device according to the invention, according to the third processing stage III, with a cutting tool following Procedural steps from the rest position of the tools necessary: control of the pneumatic and electrical adjusting elements, wherein a skid moves from the rest position to a processing position and at the same time a cutting tool from its rest position to a pre-position. Subsequently, the cutting tool is brought by oscillation of the electric adjusting element from its pre-position in an oscillating processing position, thereby releases the rocker II of the cutting tool simultaneously from the driver, which is arranged on the rocker I of the skid, whereby a complete Durchperforieren a cardboard, in particular a corrugated cardboard or the various layers of corrugated board, creating a perforation line. The cutting tool produces a perforation line which basically perforates all layers, for example, in the case of a corrugated board in the single-waved region, the outer cover, the shaft and the inner cover, ie two outer layers and the intermediate layer.

The production of a scribe line with the processing device according to the invention is carried out according to the fourth processing stage IV with a cutting tool, the following steps from the rest position of the tools are necessary: Control of the pneumatic and electrical adjustment, with a skid from the rest position to a machining position and at the same time the cutting tool its rest position moves into a processing position, this releases the rocker II of the cutting tool from the driver, which is arranged on the rocker I of the skid, whereby a scoring or scratching of the cover layer of a cardboard, in particular a corrugated cardboard or a composite material, whereby a scribe line is formed , The cutting tool generates a scribe line, which basically scratches or cuts through only one layer, for example, in the case of a corrugated cardboard in the single-waved region, either the outer cover or the inner cover, ie only one cover layer.

The electrical adjusting element is thus able to approach several different processing positions highly dynamically. In the rest position, the force of the pneumatic adjusting element is largely absorbed by a pivot joint IV of the lever II, so that the electric adjusting element does not have to permanently apply the full force in order to maintain a machining position. The force that is required for this, arises from the weight of the scoring tool and the cutting tool, as well as the force from the pneumatic adjustment.

In order to reach the machining position of the groove, the electric adjustment moves into the processing position defined for this purpose. The scoring tool is held in the processing position by means of the pneumatic adjusting element. The machining position is clearly defined by a stop. In this position, the driver has no contact with the cutting tool. The electric adjusting element is connected to the cutting tool and is held in this position. For cutting, the cutting tool is brought into the processing position by the electrical adjusting element. For the processing stage of the perforation, the electrical adjustment oscillates. The cutting tool used here is a toothed, non-driven, but rotatably mounted circular blade. From this description, the expert can see that with the processing device according to the invention, even without having to go to the rest position, can be changed from one processing stage to the next processing stage. That is, at the processing stage I, the grooving, the next processing stage II, the cutting and the cutting, the next processing stage III, the perforation and / or the next processing stage IV, the scribing, can join. The processing methods would then proceed as follows, as explained below. As an example, three of the many possible different variants of the changing processing methods in a processing process, with the aid of the processing device according to the invention, are listed here.

Starting with the examples, the production of a cutting line, which can follow a crease line, is shown here. The production of a score line is carried out in the processing stage I according to claim 13, while the production of a cutting line in the second processing stage II, according to claim 14 takes place. If, however, the production of a cutting line is carried out following the groove, without the tools first moving into the tool rest position, other method steps result according to claim 17. The following process steps are then to be carried out with the scoring tool and the cutting tool: Control of the pneumatic and electrical adjusting elements, the skid blade remaining in the machining position and the cutting tool being lowered from its pre-position to its machining position, the rocker II of the cutting tool simultaneously being released from the driver , which is arranged on the rocker I of the skate, whereby a complete cutting through a cardboard, in particular a corrugated cardboard or the various layers of a corrugated cardboard takes place.

In other words, the next processing stage III, the perforation and the scratching, the next processing stage IV, can follow the processing stage I, the grooving, the next processing stage II, the cutting and the cutting.

To produce a perforation line with the processing device according to the invention, the following process steps are necessary in the third processing stage III, which adjoins the second processing stage II, the cutting, with a cutting tool: Control of the pneumatic and electrical adjustment elements, the skid in the processing position remains and the cutting tool moves by lifting from the machining position and thus from the material in a pre-position. Subsequently, the cutting tool is brought by oscillation of the electric adjusting element from its pre-position in an oscillating processing position, thereby releases the rocker II of the cutting tool simultaneously from the driver, which is arranged on the rocker I of the skid, whereby a complete perforation of a workpiece.

In the production of a score line with the inventive processing device out of the fourth processing stage IV, which follows the third processing stage III the perforation, the following process steps are necessary with a cutting tool: control of the pneumatic and electrical adjusting elements, wherein the skid remains in the processing position and the cutting tool moves by lifting from the machining position and thus from the material in a pre-position. Subsequently, the cutting tool is brought into a machining position for scoring, it releases the rocker II of the cutting tool simultaneously from the driver, which is arranged on the rocker I of the skid, whereby a score of a paperboard, in particular a corrugated cardboard or the various layers of corrugated takes place.

Furthermore, it is possible to change directly from the processing stage I, the grooves, to the processing stage III, the perforation, or from the processing stage I to the processing stage IV, the scratches. Of course, reciprocal alternation between the processing level IV and the processing level III or II are given at any time. A change of processing levels I, II, III, IV with each other is guaranteed due to optimal software.

With the combination of the various components and the intelligent control of the tools and drives, a new processing device is created according to the invention, which meets the highest demands in the processing of corrugated cardboard. Such a processing device increases the quality of the score lines and cutting lines in the production and offers many advantages, especially for small batches of sheets and / or cardboard, due to the variable use of the tools. Due to the advantageous construction of the processing device, it is possible to react very quickly and variably to an adjustment of the different requested lines.

The processing device is a processing station that is inserted into an automated packaging system that enables on-demand manufacturing of customized packaging materials. As a base material, for example, an endless corrugated cardboard is used, which is arranged on a pallet behind the machine provided. The system provides an individual carton blank, e.g. It consists of a cross-cutting function and several longitudinal cutting functions, which may consist of several juxtaposed processing devices. These processing devices are capable of performing creases, cuts, perforations and scratches or to introduce them into the material. With the help of these processing devices fully automatic carton blanks can be produced.

The invention is not limited to the illustrated and described embodiments, but also includes all the same in the context of the invention embodiments and means. Furthermore, the invention has hitherto not been limited to the feature combination defined in the independent claim, but may also be defined by any other combination of specific features of all the individual features disclosed overall. This means that in principle virtually every single feature of the independent claim can be omitted or replaced by at least one individual feature disclosed elsewhere in the application.

A concrete embodiment of the invention is shown in the drawings 1a . 1b and 2 shown purely schematically and will be described in more detail below. Further details and embodiments of the invention can be taken from the following description and the drawings. It shows:

In principle, it is the processing device 1 to create a longitudinal, creasing 38 , Cutting 39 Perforating 40 and scratching 41 Device comprising a scoring tool 2 consisting of a skid 11 and a cutting tool 3 transverse to the web running direction (translation direction T1) of the material, in particular corrugated cardboard 37 , is arranged displaceably. It was an object, the embodiment of the processing device 1 to keep relatively narrow and slender, to order longitudinal lines to be created next to each other tight. Therefore, the processing device 1 a slim carrier frame 8th which, in principle, has to fulfill three technical functions. The first function is to have at least one linear guide 9 , in particular two linear guides 9 . 9 ' to provide. The linear guides 9 . 9 ' comprise one or more crossbeams (not shown), which are arranged in a cardboard machine. The translational movement of the processing device 1 transverse to the transport direction T1 of the sheet-like elements, see for example 2 , takes place with the aid of a corresponding drive means 10 , The drive means 10 for the transverse drive and the pneumatic adjustment element 5 and the electric adjusting element 7 are so in the support frame 8th integrated that their width is the width of the two tools 2 . 3 only slightly exceeds. The pneumatic adjusting element 5 has at the upper end a pivot VI 43 and at the bottom of a hinge III 26 , on. The upper pivot VI 43 serves to fasten the pneumatic adjusting element 5 on the support frame 8th while the lower hinge III 26 the attachment of two levers I 4 and II 18 serves. The electric adjusting element 7 also has a swivel joint VII at the upper end 44 and at the bottom of a hinge II 22 , on. The upper pivot VII 44 serves to fasten the electrical adjusting element 7 on the support frame 8th while the lower hinge II 22 the attachment of a swingarm II 20 serves.

In the resting and tool change position of the pneumatic adjusting element 5 is the hinge III 26 , VI 43 of the pneumatic adjusting element 5 and the pivot IV 27 of the lever II 18 , approximately on a straight line, that of the axis of the piston rod I 30 equivalent. While in the machining position of the pneumatic adjusting element 5 the hinge III 26 , VI 42 of the pneumatic adjusting element 5 and the pivot V 28 of the lever I 4 lie on a straight line, which is the axis of the piston rod I 30 equivalent.

The pneumatic adjusting element 5 can the swingarm I 19 from the rest position, only pivot to a defined point in the direction of the machining position. This defined point sets the maximum swing of the swingarm I 19 firmly and is by a fixed lever 45 who is at the swingarm I 19 is set. The fixed lever 45 comes at a stop 46 who is on the rack 8th is arranged to concern when the second rocker II 20 with the cutting tool 3 in the processing position, z. B. cutting 39 , moves. The processing position is z. B. the position of the skid 11 if this on the cardboard 37 comes to rest and dips something in it.

Other tasks were fulfilled in the second function. This feature is to provide lean drive means and place them in a rack 8th to integrate. The solution consists of drive means consisting of a pneumatic adjusting element 5 and an electric adjusting element 7 are formed. The control of the adjustment elements 5 . 7 via control devices, which are not shown here. The operation of the adjusting elements 5 . 7 is apparent from the foregoing description.

The solution of another object can be found in the third function. This function also has the requirement of the slim design of the processing device 1 to meet and to reduce the dimensions in width. The third function essentially concerns the tools for grooving, cutting, perforating and scoring. The tools consist of a scoring tool 2 and a cutting tool 3 , wherein the scoring tool 2 as an elongated component 11 , preferably as a skid 12 , is trained. In order to maintain a slim design, it was necessary to use the skid 12 with the cutting tool 3 to unite. For this purpose, the skid 12 a longitudinal slot 29 on, the integration of the cutting tool 3 in the skid 12 allows.

The in the skid 12 arranged longitudinal slot 29 runs in the vertical direction T3 on the one hand from the top 14 to the bottom 15 as a continuous slot 29 and on the other hand in the horizontal direction T2. On the bottom 15 the skid 12 becomes the crease edge 13 or scoring surface 13 partly from the longitudinal slot 29 breached. The longitudinal slot 29 is, in the longitudinal and transverse direction of the skid 12 considered, in the middle of the skid 12 arranged and at its two longitudinal ends 31 . 32 closed. The length of the longitudinal slot 29 depends on the one hand on the diameter of the circular cutting tool 3 and on the other hand according to its immersion depth in the material to be cut. This results in the longitudinal slot 29 approximately a circle portion formed of a chord, an arc length and a section height. The length of the longitudinal slot 29 corresponds approximately to the length of the chord. Furthermore, the length of the longitudinal slot 29 designed so that after the two longitudinal ends 31 . 32 again one, considered in the longitudinal and transverse direction complete creasing edge 13 or scoring surface 13 for the skid 12 is available so that the incoming material or the incoming sheets / cardboard on a closed creasing edge 13 or scoring surface 13 to meet. The width of the longitudinal slot 29 corresponds to the thickness of a cutting tool 3 plus a predetermined tolerance, to a certain lateral distance of the cutting tool 3 in the longitudinal slot 29 to achieve. The crease edge 13 or scoring surface 13 can have different shapes, viewed in the longitudinal and transverse directions. Viewed in the longitudinal direction or the direction of translation T2 has proved to be advantageous convex, in particular convex shape. The convex shape has a radius of at least 250 mm up to 400 mm, preferably 350 mm. Also a wavy shape and other similar shapes are conceivable. Viewed in the transverse direction, all known from the prior art forms come into consideration. Furthermore, the skid has 12 fastener 33 . 33 ' on, with which the skid 12 on a swingarm I 19 is fastened.

As the processing device 1 According to the invention, no rotary drives for the tools and their adjustment, have the skid 12 and the cutting tool 3 via linear adjusting drives (adjusting elements 5 . 7 ) and lever mechanisms I 4 , II 6 They with the adjustment elements 5 . 7 connect. The lever mechanism I 4 consists in principle of a rocker I 19 , a lever I 17 , a lever II 18 and a piston rod I 30 of the pneumatic adjusting element 5 while the lever mechanism II 6 in principle, a swingarm II 20 and a piston rod II 34 of the electrical adjusting element 7 is formed. The lever I 17 is arcuate and provides the longer lever I. 17 opposite the lever II 18 in which the lever I 17 the connection between the swingarm I 19 and the pneumatic adjusting element 5 manufactures. The lever I 17 has at its joints pivot joints III 26 , V 28 on. The lever II 18 is the shorter lever and provides the connection between the support frame 8th and the pneumatic adjusting element 5 ago, and this lever II 18 at its joints pivot joints III 26 , IV 27 having. The hinge III 26 is the common pivot III 26 from lever II 18 , from the piston rod I 30 and the lever I 17 , The swingarm I 19 also has a hinge I at a free end 22 on, and in the longitudinal direction of the rocker I 19 considered, at the other free end, is a taker 24 arranged. The one in the front area 23 the swingarm I 19 arranged drivers 24 has a right-angled hook 25 up in the direction of the swingarm II 20 points and on the upper longitudinal edge 35 the swingarm II 20 can rest. When the swingarm II 20 moves into the processing position for cutting, the rocker II dissolves 20 off the hook 24 and there is a small gap between the hook 24 and the upper longitudinal edge 35 the swingarm II 20 ,

The swingarm II 20 is part of a lever mechanism II 6 and is at one end via a hinge I 21 on the support frame 8th and at the opposite end via a pivot II 22 with the electrical adjustment 7 connected, wherein on the rocker II 20 a cutting tool 3 is arranged, which in the longitudinal slot 29 a skid 12 intervenes. The hinge II 22 is the common pivot II 22 from the swingarm II 20 and the piston rod II 34 of the electrical adjusting element 7 , The electric adjusting element 7 forms an oscillator with a positioning converter (not shown). With the help of the oscillator, the cutting tool 3 also create perforation lines. From the following 2 are the, in a cut 36 , with only two tools 2 . 3 different producible creasing and cutting lines, can be seen.

In the 2 is a perspective view, for example, a flat blank 36 made of cardboard, preferably a corrugated cardboard 37 , represented, from which later a packaged product, in particular cardboard or the like, can be folded. Of importance for the invention is that the blank 36 not just multiple score lines 38 , Cutting lines 39 , Perforation lines 40 and scribe lines 41 but that in a longitudinal line 42 can be arranged alternately one behind the other. In the field of creasing lines 38 is the material, especially cardboard 37 , By deformation without material removal or by local compression with the skid according to the invention 12 emerged to be easier kinking, folding or folding the cardboard 37 to enable.

In the area of the cutting lines is the cardboard 37 in all layers with the help of a cutting tool 3 completely severed. While the cardboard 37 in the area of perforation lines 40 with the help of the same cutting tool 3 was severed only locally in all layers, severed the scribe line 41 also with the same cutting tool 3 only one cover layer. Due to the processing device according to the invention and its narrow design, the different longitudinal lines 42 be arranged relatively close to each other.
