Definitions

  • the invention relates to a method for automatic detection from on trains, especially from packaging material, in regular Spacing of printed marks from prints, which the print marks and at regular intervals in the same Path of movement like the printed marks applied by external prints exhibit.
  • the invention further relates to a device for Carrying out the method with a sensor for scanning the Imprints and an evaluation unit connected to the sensor.
  • packaging machines process packaging material in the form of long material webs that are available as bobbins. When a running web is used up, the new one should Web if possible without manual intervention with the running web get connected. This ensures continuous operation the packaging machine.
  • the invention is therefore based on the problem, an improved one Recognize print marks to create that error-free even then works if between the print marks in the same Path of movement as the print marks are applied by external prints.
  • the method according to the invention is to solve this problem characterized in that the widths of the prints and the Distances between, especially neighboring, imprints determined and if width and distance are predetermined Values essentially match, an imprint as a print mark is recognized.
  • a device is to solve this problem characterized in that the evaluation unit such is designed that the widths of the Imprints and the distances between, especially neighboring, Imprints can be determined and if width and distance substantially match predetermined values Imprint is recognizable as a print mark.
  • the width of prints and the following Recognized and measured empty spaces and with entered reference values compared. If they match the reference values, an imprint is recognized as a print mark. In this way one can reliably differentiate between external printing and printing marks. In particular, you can identify errors in this way Avoid printing as print marks.
  • the recognized print marks are used for the control of so-called Splice processes or processes for connecting running processes used with new material web. Thereby at Connect the material webs positioned so that the Keep print marks evenly spaced in the area of the connection.
  • the speed is preferably one that is running and / or new Bobbin carrying material web depending on the degree of filling of a Web storage and the speed or speed of the operated Machine or the conveyor speed of the web is calculated and set.
  • the respective one is also preferred Bobbin diameter taken into account.
  • This speed coupling the bobbin at the speed of the declining machine has that Advantage that the pendulum deviations of the web store are reduced become. As a result, the pendulum accelerations or Inertial forces in the web store are reduced, so that the mechanical Tension in the web is constant.
  • a drive e.g. B. a servo motor, gives the speed of the running or new Bobine.
  • the servo motor is being considered the pendulum deviation and machine speed and especially that Bobbin diameter controlled so that the desired bobbin speed sets.
  • the remaining quantity or length on a reel is preferred wound web and / or the bobbin diameter determined from the angles of rotation of the bobbin and one running along with the track Deflection roller, especially taking into account the Circumference of the pulley. It can also be the length of one of the Bobine subtracted track or the path of a die Carriage sled can be used.
  • the angle of rotation the bobbin is detected by a rotation angle sensor. You can also change the angle of rotation of the idler pulley via a rotation angle sensor or a counter for counting of the revolutions of the deflection roller. You can also use of a sensor on the moving carriage Determine sledge. These sizes reach a central one Computing unit that calculates the bobbin diameter from the sizes. This arithmetic unit can also from the detected quantities the remaining quantity or length of the wound on a bobbin Calculate the path.
  • FIG. 1 shows a material unit 10 of a packaging machine in a schematic view.
  • Rotatable on an axis 11 supported bobbin arm 12 are located at the ends of the bobbin arm 12 a running bobbin 13 and a new bobbin 14.
  • a material web is wound on each of the bobbins 13, 14.
  • Such material webs are used in particular in the production of blanks for cigarette packs as well other used in connection with the packaging of cigarettes Packaging units.
  • the material web 15 of the expiring Bobine 13 becomes part in the direction of arrow 16 the packaging machine conveyed from the material web Manufactures packaging.
  • the Gripper carriage 20 After grasping the end of the new material web 17, the Gripper carriage 20 in the direction of arrow 21 in its lower, fully drawn position. The exact position will controlled by a sensor in the form of a light button 22, the Print marks recorded on the material web. The linear slide 19 pulls the new material web 17 down so far that a print mark is in a certain position. On second sensor in the form of a light button 23 scans the print marks the running material web 15.
  • Deflection rollers 24-28 guide the running material web 15 from the running bobbin past the second light switch 23 a material store 32.
  • the deflection roller 24 guides the outgoing one Material web 15 past the new bobbin 14.
  • In the area between the deflection rollers 25, 26 is the one running Material web 15 essentially parallel to the new material web 17th
  • Another deflection roller is located between the deflection rollers 27, 28 29 arranged a counter for counting the number of revolutions the guide roller 29.
  • the counter receives from so-called initiators 30, 31, d. H. non-contact sensors, Signals counted by the counter. From the number of Revolutions, in particular also fractions of revolutions, can be moved to the length of the pulley 29 Close web 15.
  • the diameter or the extent of the deflecting roller 29 The conversion of turns in lengths takes place in a not shown Control unit.
  • the length of the funded Material web 15 also by a rotary encoder, also taking into account the diameter or scope the guide roller 29, determine.
  • the material store 32 each has a row of upper deflection rollers 33 and lower pulleys 34. It serves to delay the conveying movement of the running material web 15 in Area between the pulleys 24 to 28, for example when connecting the running material web 15 with the new one Material web 17 to compensate. To ensure this balance, the row of lower guide rollers 34 is displaceable in height arranged. The material storage is due to this displaceability 32 capable of different lengths of material to record.
  • the row of upper pulleys can be used 33 can be arranged adjustable in height. As well it is possible to have both upper and lower rows of pulleys 33, 34 height adjustable position. Ultimately there is a change in the relative position of the upper row Deflection rollers 33 to the row of lower deflection rollers 34.
  • a further initiator 35 is attached to the gripper slide 20 and serves to determine the exact position of the gripper slide 20 on the linear guide 19.
  • the travel path S of the gripper carriage 20 can be determined on the basis of the determined position of the gripper carriage 20.
  • the angle of rotation of the new bobbin 14 is designated by ⁇ .
  • Fig. 2 explains the automatic recognition of the correct print mark and shows a material web 36 with print marks 37-39. Foreign prints 40-42 are located between the print marks 37-39, which are called imprints. The dashed lines indicate the beginning or end of a cut.
  • the invention enables those among the imprints "filter out" which represent the print marks. This is done automatic recognition of the correct print marks 37-39 over two criteria.
  • the width 43 of the prints on the other hand, the distance 44 between two prints was measured.
  • the distance and the width are determined using the light sensors 22, 23 determined and the measured values of an evaluation unit fed.
  • the evaluation unit previously has reference data for the width of a print mark and the distance between one Received print mark and a third party print.
  • the evaluation unit compares a measured width with the previously entered Width and a measured distance with the previously entered Distance and generates a corresponding signal if the values essentially match. This generated signal indicates the recognition of a print mark.
  • This method also allows print marks to be made reliably can be recognized correctly when viewed in the direction of movement between the printing marks 37-39 also external prints 40-42 are arranged. It is quite possible that external printing is the same As wide as the print marks and yet reliable a distinction is made between external printing and printing marks can, because in addition to the width, the distance between prints is taken into account.
  • Fig. 3 explains the bobbin speed for driving the active Bobine, i.e. the bobbin, from which the material web directly is fed to the declining packaging machine. In Fig. 1 this would be the running bobbin 13.
  • the active bobbin is driven by an engine, not shown.
  • the speed the bobbin is specified by the drive. This speed is represented by the lower block 45.
  • the bobbin speed 45 is dependent on that shown as block 46 Pendulum deviation and that shown as block 47 Machine speed.
  • Pendulum deviation means the deviation of the material storage 32 of a normal degree of filling and Machine speed the working speed of the packaging machine in relation to one in the packaging machine, rotating reference wheel.
  • the machine speed is in the Usually dependent on the conveying speed of the material web in the area of the packaging machine, i.e. especially in the area downstream of the material store 32.
  • the bobbin diameter determined can be determined use for the following operations. First, you can look at of the bobbin diameter is the end of the running material web predict and accordingly shortly before the expiring Start the splice process. Second, you can use of the bobbin diameter the angle of rotation ⁇ of the bobbin in convert a web length. Third, you can with help of the bobbin diameter the bobbin speed to the speed of the adjust decreasing machine.
