Definitions

  • the above invention relates to a method with which it is possible to automatically move printing cylinder receiving carriages into the printing elements.
  • rotary printing presses consist of a series of printing elements which are arranged at a distance from one another and are equipped with known mechanical devices which make it possible to move the paper web to be printed by a large number of printing elements arranged one behind the other.
  • Each of these printing elements has a pressure roller in a known manner, which has the task of pressing the paper web against a printing cylinder.
  • Each printing cylinder is mounted in its own receiving carriage and each receiving carriage has a known doctor device and an ink application device.
  • a device has become known from the prior art, in which a transport device is provided in axis with the printing elements, on which the printing cylinder receiving carriage are arranged to move the carriage from a waiting position into the space between each two printing elements and then to drive the corresponding printing cylinder receiving carriage into the printing element.
  • the cylinders are pushed through the individual printing units in order to occupy the subsequent free space between two printing elements and then deposited again on the transport device by a transverse movement.
  • This known device has the disadvantage that it is necessary to provide a deep channel in the longitudinal direction of the rotary printing press, which channel is suitable for receiving the components for the transport device of the printing cylinder receiving carriage.
  • a rotary printing press has also become known in which an attempt has been made to reduce the downtimes for exchanging the printing cylinder receiving carriages to reduce the fact that for each printing element there is a double printing cylinder receiving carriage, that is to say a receiving carriage which is designed to receive two printing cylinders, two doctor blades and two corresponding ink application devices.
  • the object of the above invention is to avoid the disadvantages of the prior art and a method to propose, in which it is possible to dispense with a transport device for the printing cylinder receiving carriage and consequently also with a corresponding receiving channel for this transport device and to make it possible to keep a printing cylinder receiving carriage waiting while providing for a limited space between two printing elements, and thereby to limit the length of the entire rotary printing press to a minimum and at the same time to open up the possibility of carrying out the exchange of the printing cylinder receiving carriages simply and with short times.
  • this object is achieved by a method which is characterized in that a simultaneous shifting of all printing cylinder receiving carriages (A1) which are located in the printing elements (1, 2, 3) together with all printing cylinder receiving carriages (B1) which are in the waiting position are located between the corresponding printing elements (1, 2, 3) in a feed direction (f) and that for the subsequent replacement of the printing cylinder receiving carriages, the printing cylinder receiving carriages (B1) located in the printing elements (1, 2, 3) are shifted, and the printing cylinder receiving carriage (A2), which is in the waiting position between the printing elements (1, 2, 3), takes place simultaneously and together, in the opposite direction (g).
  • each printing element 1, 2, 3 is traversed by a web 4 to be printed.
  • a printing cylinder receiving carriage A1 is arranged in each printing element 1, 2, 3.
  • Each receiving carriage A1 is equipped with a pressure cylinder in a known manner. Furthermore, each carriage A1 has a known doctor device and a known ink application device.
  • a pressure roller 5, 6 or 7 is provided in each pressure element 1, 2, 3, which can be raised and lowered and presses the web 4 against the pressure cylinder of the receiving carriage A1.
  • Fig. 1 the rotary printing press is shown schematically during the printing process.
  • the receiving carriages B1 are then moved along the dash-dot line S, as shown in FIG. 5. As can be seen from FIG. 6, the free spaces which have now formed on the left side of the printing units 1, 2 and 3 are occupied by new receiving carriages B2, which remain in the waiting position.
  • the entire carriage group consisting of the pick-up carriages A2 and the pick-up carriages B2 is again moved in the direction of the arrow f, that is to say from left to right, whereupon the loading cycle is repeated.
  • the inventor has proposed that during the process of replacing the printing cylinder receiving carriages, the entire carriage group (consisting of printing cylinder receiving carriages inside the printing units 1, 2 and 3, as well as replacement carriages, which are arranged in the waiting position in front of the printing units 1, 2 and 3) with a pendulum-like displacement movement once to the right and then move it to the left altogether, the inventor noticed that the devices for controlling and moving the receptacles can be extremely simple.
