Definitions

  • the invention relates to a device for feeding a web provided with register marks according to the preamble of claim 1.
  • B. can be a printed paper web which is to be divided into individual sections on which the printed image must appear as precisely as possible centrically.
  • the invention particularly relates to the case that the web is continuously conveyed, as is required at higher processing speeds.
  • a fixed sensor e.g. B. a photocell which responds to the register marks.
  • the time difference between the response of the photocell and a predetermined target time is measured, and a correction device is then activated on the basis of the measured difference. Because of the measurement process, however, this is complex in terms of circuitry.
  • the object of the invention is to provide a device according to the preamble of claim 1, with which a time measurement can be dispensed with.
  • the device consists of two transport rollers 1 and 2, a deflection roller 3 and a cutting station 4.
  • the transport rollers 1 and 2 are mounted on shafts 6 and 7, respectively.
  • the shafts 6, 7 are in turn supported in a stand 8.
  • a gear 9 and the winding part 10 of a magnetic coupling 11 are fixedly connected to the shaft 7.
  • An armature plate 11a of the magnetic coupling 11 is screwed to the transport roller 1.
  • the shaft 7 is driven in a known manner, not shown.
  • a gearwheel 12 Connected to the shaft 6 is a gearwheel 12 which has the same number of teeth as the gearwheel 9 and meshes with it, as well as a freewheel 13 and a disk 14.
  • the disk 14 and the shaft 6 have a bore into which a glass fiber bundle is inserted 15 is inserted.
  • a photocell 16 is arranged, by means of which (via the glass fiber bundle 15) the register marks located on the paper web are detected.
  • the function of the device is now as follows: When the paper web 5 is fed normally, the transport roller 2 is driven via the shaft 7, the gearwheel pair 9, 12 and the freewheel 13.
  • the diameter of the transport roller 2 is selected so that its circumference is approximately 2/10 mm smaller than the distance between the register marks on the paper web 5. The feed of the paper web 5 is therefore somewhat too small. If the exit point 17 of the glass fiber bundle 15 is opposite the transport roller 1, the photocell 16 is switched on, however, due to the insufficient feed of the paper web 5, no register mark is recognized.
  • the magnetic coupling 11 is switched on by a device (not shown) for correcting the feed in the form of a control circuit known per se, which is controlled by the photocell 16.
  • the paper web 5 is thus fed via the shaft 7, the magnetic coupling 11 and the transport roller 1; the freewheel 13 overhauled.
  • the diameter of the transport roller 1 is selected so that its circumference is approximately 2 mm larger than the distance between the register marks on the paper web 5, so this is conveyed more quickly.
  • the register mark for the exit of the fiber bundle 15 must therefore catch up.
  • the output signal of the photocell 16 changes, and this causes the magnetic coupling 11 to be switched off.
  • the position correction which is carried out by the magnetic coupling 11, simply works until the target position is reached.
  • the circumferences of the transport rollers 1 and 2 can also be matched to a multiple of the register mark spacing, so that a correction is only made for every second or third section, the difference between the register mark spacing and the The circumference of the transport roller 2 is then chosen to be correspondingly smaller.
  • the circumference of the transport rollers 1 and 2 could be matched to half the register mark spacing in the case of a very large section length, so that a correction is made only every second revolution; so the diameter of the transport rollers 1 and 2 is not too large.
  • the photocell 16 can also be used with the oil sports roller -2 can be arranged all around, but then sliding contacts are necessary, which are not necessary when using the light guide 15.
