Description

The invention relates to a method for determining the machine-dependent dressing requirement with the features of claim 1, a method for determining the order-dependent dressing requirement according to claim 4 and a method for creating a dressing sheet according to claim 8.

State of the art

As punching the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds. Also the practices practiced in print finishing, such as punching with punch, corner punching and register punching are counted to this area. The punching takes place against a punching pad or against stamp, in some cases it is also shearing operations. Packaging materials made of paper, cardboard, cardboard or corrugated board are mainly punched in sheet format but also as webs. Even materials such as film (in-mold), various thin plastics or aluminum foil can be processed accordingly. When punching but also creasing lines or blind embossing can be introduced into the benefit. This complex process makes it indispensable to punch the sheets individually. Since the end products are sophisticated packaging in terms of technical and graphic design (such as packaging for cosmetics, cigarettes, pharmacy, food, etc.), special requirements are not only placed on the packaging materials themselves, but are also punching tools for optimum results required with the smallest tolerances and extremely precise and reliable punching machines. Flatbed punching best meets these demands.
In flatbed sheet punching machines, the printed sheets stacked on a pallet are fed to the punching machine. In the machine are in one Aligning the sheet to be punched precisely aligned, taken from a gripper carriage and positioned exactly in the punching device between a fixed undercounter and a vertical over a toggle lever or eccentric upper table. Alternatively, machines are known in which the upper table is fixed and is moved for the punching operation of the lower table against the upper table.
Also known are flat bed web punching machines that further inline webs coming from web presses.

In known sheet punching and embossing machines, which are used for punching, breaking, embossing and depositing sheets of paper, cardboard and the like, it is known to move the sheets by means of gripper carriage through the individual stations of the machine. A respective gripper carriage has a gripper bridge, to which grippers are fixed, which grasp the arches at a front end. A gripper carriage further has lateral carriages, which are connected to endless chains of the transport system and whereby the gripper carriage to be moved by the machine. By this type of movement of the sheets through the machine, a continuous work in the individual successively arranged stations of the machine, in particular punching, break-away and Nutzentrennstation allows.

Such a flat bed punch is for example from the DE 30 44 083 A1 known. The two tables are equipped with cutting and scoring tools or corresponding counter tools with which punched out of the cyclically guided between the table surface sheets the benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a designated Nutzentrenneinrichtung.
In order to obtain high quality products, the punching pressure in the sheet punching and embossing machine must be adjustable according to the sheet being processed.

Like in the DE 30 44 083 C3 described, this is done by moving wedge-shaped steel plates. These steel plates are located between eccentric shafts and the driven upper table. By moving the wedge-shaped steel plates, the distance between the moving upper table and fixed lower table, and thus the punching force, is changed.
The various devices for adjusting the punching force according to the prior art have in common that the punching force can only be adjusted globally, ie based on the entire surface of the crucible. Due to the design, however, an uneven punching force distribution over the surface of the crucible is present in all stamping and embossing machines according to the prior art. The punching force is introduced via individual force introduction points and thus does not affect the entire crucible surface. Depending on the rigidity of the crucible, there is a deformation of upper and lower table, which in turn results in an uneven punching pressure distribution over the surface of the crucible. Also height differences of the punching or Rillmesser, as well as the wear of the knife cause an uneven punching pressure distribution. The unequal punching pressure in turn causes an unclean cutting of the cutting blade of the punching tool or an insufficient pronounced creasing of the creasing blade of the stamping tool.
In the prior art, this problem is solved by the punching blades are individually highlighted. Depending on the deviation from the nominal punching force, the punching knives on the back of the tool are glued behind with paper or plastic strips of various thicknesses. This so-called trimming is very time-consuming and must be done at machine standstill. Depending on the number of punching blades and the shape to be punched, trimming can take several hours. The high set-up time results in low machine productivity.

The DE 35 31 114 A1 describes a method and a device for pressurizing a press for producing embossing tools. The press is operated separately and independently of a sheet punching and / or embossing machine. The press has a large number of hydraulic pistons which carry a pressure plate. The pressure plate serves to emboss the tools. The pistons can be electrically controlled via a control panel, whereby the pressure build-up on the pressure plate can be varied precisely and specifically.

The DE 39 07 826 B2 describes an apparatus for producing stamping tooling, namely an impression machine. In order to be able to relocate the punching tool preparation into the impression machine, in a first step the topography of the pots of the punching machine is detected. The topography of the crucible is then simulated in the impression machine below. This makes it possible that the punching tools can be dressed in the impression machine and the punching machine can continue to operate during this trimming. The effort for trimming the punching tools is not reduced thereby.

The EP 2 327 521 A1 discloses a method for determining the required dressing requirement. For this purpose, a thin sensor film between crucible and punching tool is used, which measures the local pressure present. Based on this so determined actual pressure distribution, a neediness distribution is determined. This can be displayed or output and thus simplify the creation of a trimming sheet significantly. A disadvantage of this method is the high cost of the sensor film; it is difficult to perform the sensor film so stable that it is not destroyed at adjacent punching pressure.

task

The object of the present invention is to describe a method for determining the machine-dependent dressing requirement and a method for determining the order-dependent dressing requirements of a flat bed punching and / or embossing machine and a method for quickly creating a dressing sheet, which reduce the set-up time and thus the productivity of Increase machine.

This object is achieved by the method according to claim 1, claim 4 and claim 8.

The invention relates to a method for determining the machine-dependent dressing requirements of a punching and / or embossing machine, wherein the machine-dependent The need for dressing due to the shape of the punching die and the introduction of force into the crucible. So it is a dressing needs, which is independent of orders and basically exists for each order. According to this method, in a first step, a mathematical subdivision of the total area of a dressing sheet into a plurality of partial areas takes place. This can be done in particular by using a uniform grid, which is placed over the dressing sheet. A partial area can be defined either by a respective mesh of the grid or by a grid node and its direct environment. In a second step, the position and the thickness of dressing strips and trimmings are recorded on a trimming sheet. For this purpose, the consideration of each individual surface is done by itself. While dressing strips have a large length at a small width, dressing papers have a flat extension and can cover entire areas of the dressing sheet. The detection of the thickness of dressing strips and trimming can be done in particular at each grid node. This step is repeated for a plurality of trimming sheets already used in the punching and / or embossing station. The greater the number of trimming sheets available for the detection step, the more accurately the machine-dependent trimming requirement can be determined. The detection of the dressing strips and trimmings can be done advantageously by a scanner. The scanner can either scan the actual thickness of the dressing strips and trimmings or the scanner detects at least the color of the dressing strips and trimmings. Since these usually have different colors depending on their thickness, it is possible to deduce the thickness of the detected color. If the acquisition is not carried out with a scanner, this can be done by manually entering the data by a machine operator, possibly supported by CAD data from the tool production. After this data acquisition, a calculation of the mean value of the thickness of the dressing strips and trimming papers in a respective sub-area takes place, so as to determine a trimming requirement profile. The mean value can be advantageously calculated as an arithmetic mean, as a mode or as a median. The calculation of the mean value ensures that essentially the machine-dependent dressing requirement is determined, and the order-specific finish, based on tool positions (punching knife, creasing knife, embossing cliché, etc.), is eliminated. The inventive method can be determined in a simple manner, the machine-dependent dressing requirements. The finishing requirement profile obtained in the result can then be taken into account either in a respective order-specific creation of a trimming sheet or it can be created once a trimming plate, which is used for each order to reduce the trimmings. In both cases, a more uniform distribution of the punching pressure is achieved, which contributes to a better punching result and thus to higher-quality punched products.

The invention also relates to a method for determining the order-dependent dressing requirements of a punching and / or embossing tool for the punching and / or embossing machine. In contrast to the above-described method according to the invention for determining the machine-dependent dressing requirement, the order-dependent need for dressing is independent of the configuration of the crucible and of the introduction of force into the crucible. The order-dependent dressing requirement results from the order-specific use of tools on the punching and / or embossing tool. These tools include punching blades, creasing knives, rubber strips, embossing clichés, etc. According to the invention, in a first step, a mathematical subdivision of the total area of a stamping and / or embossing tool into a plurality of partial surfaces. In a second step, the position, type and characteristics of tools are recorded on the punching and / or embossing tool in each partial area. The detection can be done in particular at each grid node. Tool type means the fundamental distinction between punching knife, creasing knife, retaining rubber, embossing cliché. The expression of the tools means a closer examination of a respective tool, for example the detection of the cutting geometry of the punching blades, the edge formation of the creasing knives, the hardness of the rubber strips, the embossing depth of the embossing clichés, etc. This detection can be carried out advantageously in that precursor data from the printing plate production or used from the creation of the punching and / or embossing tool. Alternatively, the detection can also be done by a machine operator. In a next step, a tool-specific trimming requirement is determined for each sub-area, by the type and characteristic of the tool assigned to a particular sub-area Required for refurbishment in a database. In the database, in particular a respective tool type and / or a respective tool characteristic is assigned a dressing requirement value or a dressing requirement factor. The values of this allocation table represent a collection of empirical values. For example, a dressing requirement value can be assigned to a respective tool type, which is adjusted by a dressing requirement factor as a function of the respective tool characteristic. The dressing requirement is calculated for a particular sub-area and created for the total area of the punching and / or embossing tool as a need for trimming. If necessary, this trimming requirement profile can be saved.

The dressing requirement profile determined in this way can be used in a subsequent step in order to create a dressing sheet which anticipates the required order-dependent dressing requirement. The requirement of time-consuming trimming by gluing the dressing sheet with dressing strips can be eliminated or at least reduced to a minimum.

To carry out the method described above, a computer can be used, since the provisions of the order-dependent dressing requirements can then be completely automated and integrated into existing order management systems. A trimming sheet created using the trimming requirement profile can already be created before the machine is converted to the new job, so that the time required for machine retooling can be significantly reduced.

It is particularly advantageous to combine the two aforementioned methods both for determining the machine-dependent dressing requirement and for determining the order-dependent dressing requirement. The needling profiles determined in both methods can be superposed on each other and used for the creation of a trimming sheet. Alternatively, two trimming sheets can be created, which are placed together in the punching and embossing station. Further trimming by gluing the dressing sheet with dressing strips can thus be limited to a minimum.

The invention also relates to a method for producing a trimming sheet for a punching and / or embossing station of a flat bed punching and / or embossing machine, wherein the trimming sheet is profiled over its surface. In this case, according to the invention, a plastic plate, which is swellable at least on its surface, is printed with a swelling agent, using a known need for trimming. It is particularly advantageous to use an inkjet printer for printing. Depending on the amount of swelling agent applied, there is a local swelling of the plastic plate, so that it has a greater thickness and can cause a local punch pressure increase. The amount of swelling agent applied may be varied by drop size, pitch, or dot size. Also, swelling agent in different concentrations or different swelling agent can be applied by means of several inkjet nozzles. The plastic plate can be made of a suitable swellable plastic, such as an elastomer or a thermoplastic such as PVC or polyethylene. Depending on the plastic chosen, a suitable solvent must be chosen as the swelling agent.
In an alternative embodiment, the swellable plate is processed by a radiation device, eg a laser. How much the plate swells can be influenced by varying the laser power, distance, spot size of the incident laser and wavelength of the laser.
In an advantageous embodiment of both embodiments, the plastic plate after printing with the swelling agent or the irradiation and swelling can still be cured in order to achieve a higher stability of the dressing sheet.

The described invention and the described advantageous developments of the invention are also in any combination with each other advantageous developments of the invention.

With regard to further advantageous embodiments of the invention, reference is made to the dependent claims and the description of an embodiment with reference to the accompanying drawings.

In FIG. 1a the basic structure of a sheet punching and embossing machine 100 for punching, breaking and depositing sheets of paper, cardboard and the like is shown. The punching and embossing machine 100 has a feeder 1, a punching station 2, a breaking station 3 and a boom 4, which are supported and enclosed by a common machine housing 5.

The sheets 6 are separated by a feeder 1 from a stack, fed to the sheet transport system 7 and gripped by gripper bars of a gripper carriage 8 grippers at its front edge and intermittently in the sheet transport direction B through the various stations 2, 3 and 4 of the punching and embossing machine 100th pulled through.
The sheet transport system 7 has a plurality of gripper carriages 8, so that a plurality of sheets 6 can be processed simultaneously in the various stations 2, 3 and 4. The gripper carriage 8 can be driven by an electromagnetic linear drive with alternating field motors in an alternative embodiment.

The punching station 2 consists of a lower crucible, a so-called. Subtable 9, and an upper crucible, a so-called. Obertisch 10. The upper table 10 is vertically reciprocally mounted and provided with an upper tool 20 with punching and Rillmessern. The lower table 9 is fixedly mounted in the machine frame and provided with a counter-plate (not shown) to the punching and Rillmessern. The section I b is in Fig. 1b shown in more detail and is described below.

The gripper carriage 8 transports the sheet 6 from the punching and embossing station 2 in the subsequent breaking station 3, which is equipped with breakout tools. In the break-out station 3, the unwanted pieces of waste are pushed out of the sheet 6 downwards by means of the break-off tools, whereby the waste pieces 11 fall into a carriage-like container 12 inserted below the station.

From the breaking station 3, the sheet 6 enters the boom 4, where the sheet 6 is either simply stored, or at the same time there is a separation of the individual benefits. The boom 4 may also include a pallet 13, on which the individual sheets 6 are stacked in the form of a stack 14, so that after reaching a certain stack height, the pallets 14 are moved away with the stacked sheets 6 from the field of punching and embossing machine 100 can.

In FIG. 1b the punching station 2 is shown in more detail. Between the upper crucible 10, also referred to as upper table, and the lower crucible 9, also referred to as under-table, a paper sheet 6 is moved in the sheet transport direction B through the punching station 2. During the punching operation, the sheet 6 is at rest. The punching station 2 has a punching tool 20, which consists of an upper tool with a protective plate 21, with a wooden support plate 22 mounted thereon, which receives the punching knife 23. The punching tool 20 can be held by a frame, not shown, a so-called. With the opposite crucible 9, a counter-punching plate 24 is connected, which forms a lower tool. This can be constructed of a punched metal sheet (about 1mm) and a punching plate (about 5-10mm). A dressing sheet 25 is in Fig. 1b between support plate 22 and protective plate 21 is arranged. Fig. 2 shows the outer dimensions of the upper tool of a punching tool 20 and a dressing sheet 25. The total area of the upper tool 20 and the dressing sheet 25 is divided by a grid 51 into a plurality of partial surfaces 53. This division is purely mathematical, with the finest possible subdivision is desired. The representation of Fig. 2 it should represent the subdivision into sub-areas 53 purely schematically. In practice, the subdivision will be many times finer, so that very small sub-areas are formed. The lines of the grid 51 each intersect at the grid node 52. The resulting faces 53 may be defined either by a mesh of the grid 51 or by the environment of a grid node 52.

In Fig. 3 the procedure according to the first method according to the invention is shown for determining the machine-dependent dressing requirement. For this purpose, a plurality of dressing sheets 25 is used. Each trimming sheet 25 has an individually different finish with trimming strips 25.5 and trimming 25.4. In the presentation off Fig. 3 For example, sections are represented by three exemplary dress sheets 25. The first dressing sheet 25 has two smaller finishes 25.2 and one large finishing 25.3, which is formed by dressing strips 25.5. The second dressing sheet 25 has two smaller dressings 25.1, one having a wider extension. There is no dressing 25.1 between these smaller finishes 25.2. The n. Dressing sheet 25 has two smaller finishes 25.2 and one over a larger area extending finish 25.4 with dressing paper 25.4. From each trimming sheet 25, the position and the thickness of the trimming strips and trimming papers 25.2, 25.3, 25.4 are detected, for example with a scanner 31. For this purpose, the thickness of the dressing in each of the partial surfaces is determined. From the thus detected thickness of the finish, the mean value of the thickness of the finish in a respective partial area is determined in a subsequent step, in particular using a computer 70. By juxtaposing the average values for the respective partial surfaces 53, a dressing requirement profile 60 is determined for the total area of a dressing sheet 25. In the sub-areas 53, in which the dressing sheets 25 have a large finish 25.3, the dressing requirements profile 60 also provides for a large dressing requirement 42. For the part surfaces 53, for the dressing sheet 25 a small dressing 25.2 or no Have Dressing 25.1, sees the need for distress distribution 60 analogous to a low trimming needs 41 or no trimming needs.

A further example of a need for dressing 60, which can also be referred to as a need for dressing, is in Fig. 4a roughly indicated schematically. Due to the different hatchings, alternatively, different colors can be used for a visualization, it can be seen that there are areas 40 in which there is no need for dressing, that there are areas 41 in which there is little need for dressing, and that there are areas 42, in which large dressing needs exists.

Based on this visualized needles distribution 60 can subsequently, as in Fig. 4b represented, a dressing sheet 25, for example by sticking adhesive strips of different thickness, be dressed. Alternatively, the dressing sheet 25 may be formed by a film-forming process or by printing a plate. In the example of Fig. 4b No finishing took place at 25.1, at 25.2 a minor finishing took place and at 25.3 a large finishing took place.

Fig. 5a visualizes the second method according to the invention for determining the order-dependent dressing requirement. After like based on Fig. 2 described a subdivision of the total area of the punching tool 20 was carried out in a plurality of sub-areas 53, it is determined for each of the faces 53, if there is a tool, and if so, which tool type and which tool feature this has. The detection of position, type and shape of the tools on the punching tool 20 can be done either by reading the punching tool by means of a scanner or a camera 31, or it can be used precursor data 74 or a machine operator enters the data via an interface 75 in one Calculator 70 a. Preference is given to the use of the precursor data 74, since the method can be automated so easily. If a tool 23 is present in a specific subarea 53, the tool type is determined. For example, it can be a punching knife S, a creasing knife R, a rubber strip G or an embossing cliché P. For each of the tool types can also the expression of the tool be recorded in more detail. For example, for cutting blade S, the cutting blade geometries S1, S2, for Rillmesser R, the outer contours R1, R2 and for embossing dies P, the material hardness of the embossing die P1, the embossing depth P2 and the number of embossing lines in the immediate vicinity P3, etc. are determined. All known tool types S, R, G, P and their characteristics are assigned in a database 72 trimming requirements xi and trimming requirements fi. If the existing tool type and the shape of the tool are known for a subarea 53, it is possible to use the database 72 to determine a trimming requirement value xi based on empirical values or a trimming requirement factor fi. A trimming requirement 40, 41, 42 existing for the respective subarea 53 can then be determined by means of a computer 70, for example by multiplying the trimming requirement xi by the trimming requirements fi. Thus, the need for dressing 40, 41, 42 for each of the faces 53 of the total area of the punch 20 is determined. By juxtaposing the dressing requirement 40, 41, 42 of all partial surfaces 53, a dressing requirement profile 60 is formed, which can be stored in a memory 71 or buffered.

The dressing requirements profiles 60 determined in one of the aforementioned methods can then be used to create a dressing sheet 25. Using the trimming need 60, the trimming sheet 25 can by the in the EP 2 327 521 A1 and there in paragraph [0016] described method.

Alternatively, a thin plastic plate can serve as the starting product for the dressing sheet 25. This plastic plate 25 is printed by using an inkjet printer 30 with a swelling agent, see Fig. 5b , In the sub-areas 53 in which the dressing requirement profile 60 provides a dressing 41, 42, swelling agent is applied to the plastic plate 25 by the inkjet printer 30 so that it swells, thereby undergoing a local expansion and thus a finish 25.2, 25.3 is formed. The control of the inkjet printer 30 is done by a computer 70 using the data describing the dressing requirement profile 60. The dressing requirement profile 60 may be, for example, by one of the basis of the FIG. 3 or 5a have been determined.

The amount of swelling agent applied may be varied by the size of the drop (ie, the volume of a drop of swelling agent), the pitch (between the respective pressure points), or the spot size (when impinging on the disk 25). Also, swelling agent in different concentrations or different swelling agent can be applied by means of several inkjet nozzles.
