Definitions

  • the subject of the present invention is a method and a device for controlling the quality of printing and cutting in a train of machines working with sheet material for the production of packaging.
  • the production of packaging for example cardboard, corrugated or not, goes through at least three successive phases: printing, cutting and folding-gluing.
  • the quality of the final product therefore depends on the quality of each phase taken individually.
  • the present invention essentially relates to the control of the quality of printing and cutting.
  • the printing control has been carried out visually after the printing machine, according to the offse or rotogravure process, that is to say that a person educated about the requirements required as regards to the quality of the printing can, after a fairly large practice, have enough knowledge, experience and skill to be able, after a quick look at the printing of the different colors which has just been done in the corresponding groups of a printing machine, to make a judgment on the quality of the printing, that is to say to decide whether or not the printing examined is acceptable.
  • the printing machine continues its production which will be sent to the next phase, that is to say cutting; if the printing is not acceptable, the operator of the printing machine will be informed and will bring to the control of the printing machine the modifications necessary to correct the printing defect (s). It is recalled here that the printing can be done while the material is in the form of a continuous strip or in the form of successive sheets which pass.
  • Figure 1 shows a machine comprising an introduction station 1, cutting 2, ejecting 3 (waste) and receiving 4 (poses or sides).
  • introduction station 1 cutting 2, ejecting 3 (waste) and receiving 4 (poses or sides).
  • the front edge of each sheet F taken successively from the package 5 is introduced into a gripper bar 6 moved by a chain train 7.
  • the sheet F is then transported through the various work stations 2, 3, 4. It is recalled that each of these operations is carried out when the gripper bars 6 stop.
  • each sheet F is taken from a stack P to be brought to a margin table M.
  • the purpose of the table M is to effect longitudinal and lateral positioning of the sheet by relation to the working elements, such as cutting, of the machine. This positioning is carried out using front 12 and side 14 catches as shown in FIG. 2, the sheet being moved in the direction of arrow 15.
  • the catches 12, 14 therefore also have the function of correctly positioning the sheet with respect to the clips 6a of the transport bar 6, the clips 6a being intended to come into engagement with the front edge of the sheet F.
  • the printing 100 comprises one or more identical patterns juxtaposed, each corresponding pattern, after cutting, to one packing box.
  • five marks M5-M5 for locating colors are also printed in a known manner on sheet F.
  • Four first marks M1-M4 each relating to a color of a machine with four printing groups, are printed on a side edge and very close to the front edge of the sheet F.
  • these marks are arranged so as to form a square.
  • the fifth mark M5 is also printed on the lateral edge of the sheet F, that is to say outside of the printing area 100, but offset backwards.
  • the mark M5 is located exactly, seen in the direction of movement 15, in the extension of the center of the square formed by the four marks M1-M4.
  • a "CAMERA-FLASH” reading unit is placed exactly above the passage of the marks M1-M5.
  • the "CAMERA-FLASH” unit makes it possible, using a camera 10, to produce a first image, named I1, of the four brands M1-M4.
  • the "CAMERA-FLASH” unit is associated with units: "IMAGE PROCESSING SYSTEM” "OPERATOR INTERFACE” "ELECTRIC CONSOLE” “INSERTION SYSTEM” "INTERFACE MACHINE”
  • the purpose of the mark M5 is to make it possible to check whether the precision error tolerances of the position of the printing 100 relative to the edge of the sheet F. As previously described for the marks M1-M4, the last check is performs by comparison of an image I2 of the mark M5, relating to each successive sheet F during production and called "sample", with an image I'2 of the reference model F '.
  • results of the test can be used in various ways. In the case where a sheet F does not meet all the criteria, it is possible, for example, to stop the machine or to prevent the sheet F from being taken up by the clamps 6, 6a, with a view to its ejection.
  • the advantage of the system with two reading fields or targets M1-M4 and M5 lies in the fact that it increases the time available to carry out the control in question.
  • the sheet stopping time against the front stops 12 is of the order of 25 milliseconds. During such a minimal period of time, it is difficult to have the "IMAGE PROCESSING SYSTEM" unit perform all the control operations.
  • the method described above also has the advantage of indirectly controlling the positioning of the tabs 12, 14 relative to the working tools of the cutting station. Indeed, any fortuitous variation or derives from the position of the cleats 12, 14 will be automatically detected since it causes a variation in the positioning of the marks M1-M5 in the field of the camera 10.
  • camera 10 is associated with a special optical system calculated so as to be able to read marks of very small dimensions (some 1 / 10 mm in diameter) i.e. invisible to the naked eye. With such an optical system, it is easier to find a suitable place for the location of the M1-M5 marks.
