Definitions

  • the invention relates to a device for preventing machine damage in the event of a paper web tear.
  • the invention has for its object to provide a device that prevents a web already passed through a rotating cylinder work station is not pulled back into the work station.
  • the construction of the device according to the invention is simple and inexpensive, since moving elements and touch devices can be dispensed with.
  • the device can be installed in an area inaccessible to the operating personnel (e.g. on finger protection bars), so that there is no risk of injury and safety conditions are increased.
  • a rotary printing press has a last printing unit 1 consisting u. a. from rubber cylinders 2, plate cylinders 3 and an impression cylinder 4 a dryer 6, a number of driven cooling rolls 7 and some web guide rolls 8.
  • a paper web 9 passed through the printing unit 1 is coated with ink in the printing unit 1 and fed to the dryer 6 by means of the web guide rollers 8, from which the paper web 9 is guided to the cooling rollers 7.
  • paper web tears often occur due to heavy loads as a result of thermal stresses.
  • the paper web 9 which has suddenly become tension-free, adheres to the surface of the last cylinder 2 (e.g. rubber cylinder) due to strong adhesive forces, caused by the fresh application of paint, and is wound onto the cylinder 2 or one of the other cylinders becomes.
  • the paper web 9 between the break point and the printing unit 1 can sometimes have a length of more than 20 m, the elimination of such a winder not only leads to long downtimes of the machine, but also often to severe machine damage.
  • a separating device 11, 12 in the form of a paper web 9 wide knife separates the paper web 9 as soon as it comes into contact with a cutting edge 13, 14 of the knives 11, 12.
  • the knives 11, 12 are arranged stationary parallel to the axes of the rubber cylinders 2.
  • the knives 11, 12 are each fastened to a crossbar 16, 17 serving as finger protection.
  • the cutting edges 13, 14 protrude into a space 18 which is formed by the rubber cylinders 2, 2 and the cross members 16, 17.
  • the side frames of the rotary printing machine form the side cover of the room 18.
  • a narrow distance a (z. B. 10 - 30 mm) between the cross members 16, 17 offers enough space for the paper web 9, but at the same time prevents an operator from accidentally entering the Area of the knife edges 13, 14 can reach.
  • the cutting edge 13; 14 of the knives 11, 12 consists of jags or tips 19 arranged next to one another ensures that the teeth or tips 19 of the cutting edge 13; 14 safely penetrate and cut through the paper web.
  • the paper web 9 adheres to the lower or upper rubber cylinder 2 (represented by a dash-dotted line) and is wound up in the direction of rotation of the rubber cylinder 2.
  • the paper web 9 already passed through the printing unit 1 comes into contact with the cutting edge 13; 14 of the knife 11; 12 and is severed.
  • the paper web 9 is in this case deflected by an angle ⁇ (for example> 45 ° ) to its normal transport direction.
  • a separating device usually provided in front of the printing unit 1 also separates the paper web entering the printing unit. However, this device should not be the subject of the application and is therefore not described in detail.
  • a paper web 9 that is already in the printing unit 1 at the time of the web break can now still be wound onto the rubber cylinder 2.
  • this paper web 9 is so short that it cannot cause any damage to the cylinders or the printing elevators.
