There are Brand readers known which recognize the printed print marks and the Control the process of joining based on the detected print marks.
  • EP 0 211 291 discloses a device in which the initial section of the new path before a connection does not automatically move to a reference position is brought for subsequent joining, but by hand an operator must be attached to a web holder. The exact position This initial section must be recognized by hand, with only the Position of the trajectory before joining via a print mark recognition of the brand reader.
  • US 5 518 202 discloses a connection method for connecting an outgoing one railway with a new railway, in which the new railway by means of a Swing lever is brought into a connection position.
  • EP 0 831 048 A1 discloses a method for adjusting the tension of a material web. To calculate the residual length of the material web, the angle of rotation the running track is related to the length of one of the reel the running web withdrawn track piece.
  • the invention is based on the problem, an improved method for positionally correct To create connecting material webs.
  • the detected print marks are used for the control of the so-called splice processes or processes for connecting from running with new material web used.
  • the material webs are positioned in such a way during that the print marks keep the same distances even in the area of the connection.
  • the width of imprints and the following empty spaces can be detected and measured and compared with input reference values. If it matches the reference values, it will print as a print mark recognized. In this way you can reliably between foreign prints and differentiate between print marks. In particular, you can in this way error detection Avoid printing as print marks.

  • the servomotor is under consideration the pendulum deviation and engine speed and in particular the Bobbin diameter controlled, so that the desired Bobinenburniere established.
  • the length of the withdrawn piece of web is the running track determined from the angle of rotation of a running with the running web Pulley, in particular taking into account the Circumference of the pulley.
  • angle of the bobbin is detected by a rotation angle sensor.
  • These sizes reach a central one Arithmetic unit that calculates the bobbin diameter from the sizes. Likewise, this arithmetic unit from the detected sizes the remaining amount or length of wound on a reel Calculate the train.
  • Fig. 1 shows a material unit 10 of a packaging machine in a schematic view.
  • rotatable mounted Bobinenarm 12 are located at the ends of the Bobinenarms 12 an expiring reel 13 and a new reel 14.
  • a material web is wound in each case. Such webs are used in particular when making 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 the part in the direction of arrow 16 promoted the packaging machine, from the web Produces packaging.
  • Pulleys 24-28 lead the expiring web 15 of the running bobbin past the second light sensor 23 to a material storage 32.
  • the guide roller 24 performs the expiring Material web 15 past the new reel 14.
  • 26 is the expiring Material web 15 substantially parallel to the new material web 17th
  • deflection roller 29 Between the pulleys 27, 28 is another deflection roller 29, which is a counter for counting the number of revolutions the deflection roller 29 has.
  • the counter receives from so-called initiators 30, 31, d. H. non-contact sensors, Signals counted by the counter. From the number of Revolutions, especially fractions of revolutions, can be carried along the length of the guide roller 29 on the length Close material web 15. Here is the diameter or circumference of the guide roller 29 to be considered. The conversion of turns in lengths takes place in a not shown Control unit. Alternatively, you can choose the length of the subsidized Material web 15 also by a rotary encoder, also taking into account the diameter or circumference the deflection roller 29, determine.
  • the material storage 32 each has a number of upper pulleys 33 and lower pulleys 34. He serves a 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 Material web 17, compensate. To ensure this balance, is the row of lower pulleys 34 in height displaced arranged. Due to this displacement is the material storage 32 capable of different web lengths take. Alternatively, the row of upper pulleys 33 be arranged adjustable in height. As well It is possible both upper and lower row of pulleys 33, 34 height adjustable to position. Ultimately it comes to a change in the relative position of the series upper Deflection rollers 33 to the row of lower pulleys 34 at.
  • a further initiator 35 is mounted, which serves to determine the exact position of the gripper carriage 20 on the linear guide 19.
  • the travel S of the gripper carriage 20 can be determined.
  • the rotation angle sensor By means of this rotation angle sensor, the rotation angle of the respective bobbin can be detected.
  • the angle of rotation of the new reel 14 is denoted by ⁇ .
  • Fig. 2 illustrates the automatic recognition of the correct print mark and shows a web of material 36 with print marks 37-39. Between the print marks 37-39 there are foreign prints 40-42, which are referred to as imprints. The dashed lines indicate each beginning or end of a blank.
  • the invention makes it possible among the imprints "filter out” which represent the print marks. This takes place the automatic recognition of the correct print marks 37-39 over two criteria.
  • the distance and the width are using the light scanner 22, 23 and the measured values of an evaluation unit fed.
  • the evaluation unit has previously reference data for the width of a print mark and the distance between a print mark Print mark and a foreign pressure received.
  • the evaluation unit compares a measured width with the previously entered one Width as well as a measured distance with the previously entered Distance and generates a corresponding signal, if the values are essentially the same. This generated signal indicates the detection of a print mark.
  • These measurements can either only be used to initiate a connection process two webs or permanently during operation the plant / packaging machine, in particular the material unit 10, done.
  • This method also reliably allows print marks to recognize correctly when viewed in the direction of movement between the print marks 37-39 and foreign prints 40-42 are arranged. It is quite possible that foreign prints the same Have width as the print marks and yet reliable can be distinguished between external printing and print marks can, in addition to the width of the distance between imprints is taken into account.
