Definitions

  • the invention relates to a method for adjusting the pressing force of a flat bed stamping and embossing machine according to claim 1, as well as a flat bed stamping and embossing machine according to claim 7.
  • the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds.
  • 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.
  • Plastic packaging materials, film material, paper, cardboard, cardboard or corrugated board are mainly punched in sheet format but also in web format. When punching but also creasing lines or blind embossing can be introduced into the benefit.
  • Such a flat bed punch is for example from the DE 30 44 083 A1 and the US 7,658,378 B2 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 sheet benefits and at the same time pressed the necessary for clean folding grooves.
  • the waste is removed by machine tools.
  • the punched benefits can be separated in a designatedboctrenn issued.
  • the pressing force in the sheet punching and embossing machine must be able to be adjusted according to the sheet to be 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 the fixed lower table is changed, and thus the punching force. On the one hand to have a sufficient pressing force and on the other hand to reliably avoid that the punching tools acted upon with too much force and consequently destroyed, the machine operator has to the optimum pressing force grope. Together with the trimming by pasting the punching tool results in a very time-consuming adjustment process.
  • EP 1 882 565 A2 discloses a method for adjusting the pressing force of a flatbed punching and / or embossing machine, wherein the flatbed punching and / or embossing machine has at least one punching and / or embossing tool for processing a sheet-like printing material, with the following step: setting the Pressing force of the flatbed punching and / or embossing machine to the desired pressing force by means of actuators, which are individually controllable and allow a local variation of the punching force on the punching surface.
  • Object of the present invention is to describe a method for adjusting the pressing force and to provide a flat-bed punching and / or embossing machine, which greatly simplify the setting of the pressing force and the error rate and the required time for the establishment of flat-bed punching - and / or embossing machine and so reduce the disadvantages of the prior art.
  • This object is achieved by a method for adjusting the pressing force with the features of claim 1 and by a flat-bed punching and embossing machine with the features of claim 7.
  • the method according to the invention serves to set the pressing force of a flatbed punching and embossing machine, wherein the machine has a punching and / or embossing tool for processing a flat printing material.
  • job-dependent tool data which describe the individual structure of a punching and / or embossing tool from a plurality of part tools.
  • specific force data stored there are read out from a database, wherein the specific force data assign a specific pressing force to a respective sub-tool. From the tool data and from the specific force data is then a calculation of a desired pressing force. By appropriate control of an adjustment then the pressing force of the flatbed punching and / or embossing machine is set to the calculated target pressing force.
  • An advantage of this method is that the machine operator does not have to move slowly step by step to a required punching force, which achieves a good punching image, but already can begin the first punching process with a pressing force, which is close to the optimum pressing force. This significantly speeds up the machine settings during a job change so that the quality requirements are produced faster and the number of spoofing sheets caused by the setup can be reduced.
  • the effective pressing force can be corrected in an additional step after a first punching or pressing process and the assessment or assessment of a stamped or embossed printing material by the machine operator. Correction steps may be suggested to the machine operator by the machine controller of the flat bed punching and / or embossing machine.
  • the tool data comprise information on the type of a respective sub-tool and on the effective length and / or the effective area of a respective sub-tool.
  • the part tools can be distinguished between cutting knives, Rillmessern, Messerergummtechniken, embossing clichés, etc.
  • embossing clichés a distinction can be made between different cliché materials and embossing depths.
  • the tool data also includes the effective length of the respective part tool, as far as it is cutting knife, Rillmesser and rubbers or the effective area, if it is to be embossing clichés.
  • the specific force data in the database are given as the required pressing force per effective length or per effective area of a respective part tool. This means that different specific cutting forces, creasing forces, gumming forces and embossing forces are stored in the database.
  • a desired pressing force can be calculated by adding the required part per part tool Sollpress mechanism calculated as products of the length of the sub-tool with the respective associated specific pressing force or effective area with the respective assigned specific force a required set pressing force for the whole tool can be calculated.
  • the specific force data depends on the substrate to be processed, for. B. its thickness, its material composition and its format.
  • the specific force data stored in the database must be determined in advance in extensive test series in a special single test bench. Therefore, the data is provided by the machine manufacturer. The more extensive the database is, ie the more different sub-tools are depicted for different substrates, the more accurate the required and permissible desired pressing force can be calculated according to the method according to the invention.
  • Safety factor means z.
  • B. a safety factor of size 0.8, which is multiplied by the calculated from tool data and specific force data pressing force. The operator is thus enabled to grasp this reduced, calculated pressing force to an actual required and permissible pressing force, minimizing the risk of destroying punching and / or stamping tools due to excessive pressing force adjustment.
  • a distribution factor can take into account the distribution of benefits over the total area of the substrate, for example, whether the benefits are evenly distributed or not.
  • the number factor can take into account the number of uses on a substrate.
  • the size factor in turn can reflect the size of the printing material or of the punching and / or embossing tool.
  • the adjusting device for punching force adjustment comprises four adjusting wedges, which can be adjusted independently of each other. Each wedge could be given an individual adjustment movement according to a desired pressing force calculated for this area (ie quadrants).
  • the invention also relates to a flatbed punching and embossing machine with a machine control set up for carrying out the above-described method and having a workflow connection and / or an interface for transferring data from the pre-press of the printed materials to be processed and / or from the stamping - And / or embossing tool production which can either be used directly as a tool data for the inventive method or even undergo a preparation by a computer and / or an interface for entering tool data.
  • the described invention and the described advantageous developments of the invention are also in any combination with each other advantageous developments of the invention.
  • 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 21, 23.
  • the unwanted pieces of waste 11 are pushed out of the sheet 6 down with the help of the stripping tools 21, 23, whereby the waste pieces 11 fall into an inserted under the station car-like container 12 or be transported away from there.
  • the boom 4 may also include a pallet 13, on which the individual sheets 6 or benefits in the form of a stack 14 are stacked, so that after reaching a certain stack height, the pallet 13 with the Sheet stack 14 can be moved away from the area of the punching and embossing machine 100. In order not to have to stop the machine 100 during the stack exchange, auxiliary stacking devices can be used.
  • a punching tool 30 which serves the processing of four benefits.
  • the punching tool 30 has a plurality of different sub-tools, such as cutting blades 31, creasing knives 32, rubber linings 33 mounted parallel to the cutting blades 31 and in each case a round embossing cliché 34 in the middle.
  • the tool data which describe this punching tool 30 comprise the type of the respective sub-tools 31, 32, 33, 34 and the effective lengths l S , l R , l G and the effective area A P.
  • the length of the cutting blade l S is composed of all the partial lengths of the cutting blade 31.
  • the effective length of the creasing knives l R is composed of all partial lengths of the creasing knives 32.
  • the length of the rubber coating l G is composed of all part lengths of the topping 33rd
  • the effective area of the embossing clichés A P is in turn composed of the sum of the partial surfaces of the embossing clichés 34.
  • Fig. 2 is - for better clarity - each only a partial length or partial area provided with a reference numeral. If these tool data from the pre-press or the production of the punching tool 30 are known, then a direct use in the calculation of the desired pressing force otherwise, the tool data must be entered into the machine controller 15 via an interface.
  • the machine control 15 accesses a database 25 in which specific force data are stored. There, therefore, the required cutting force per meter for a particular cutting blade 31 and the creasing force per meter for a special creasing tool 32 and the required Kunststoff réelleskraft per meter for a special rubber 33 and the required stamping force per m 2 for a special embossing cliché 34 deposited , These specific values are multiplied by the corresponding length of the part tool (cutting length, crease length, length of gumming) or surface (embossing surface) and the required pressing force F is calculated by adding the values for the part tools 31, 32, 33, 34). In the machine control additional multiplication factors, such. B. security, distribution, number, and / or size factor be deposited in order to make an adjustment of the calculated pressing force before it is implemented by appropriate control of the adjuster 24 by the machine control 15.
