Definitions

  • 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.
  • punching 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.
  • flatbed punching best meets these demands.
  • flatbed sheet punching machines the printed sheets stacked on a pallet are fed to the punching machine.
  • 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.
  • 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.
  • flat bed web punching machines that further inline webs coming from web presses.
  • 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 designatedboctrenn issued.
  • the punching pressure in the sheet punching and embossing machine must be adjustable according to the sheet being processed.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the position and the thickness of dressing strips and trimmings are recorded on a trimming sheet.
  • 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.
  • the thickness of the detected color 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the amount of swelling agent applied may be varied by drop size, pitch, or dot size.
  • 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.
  • 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.
