Definitions

  • this device presupposes the presence of motor-driven forks rotatably mounted on the printing machine, which in addition to the doctor device and the ink tray also convey the printing and ink cylinder from a working position directly into various receiving devices attached to the frame of the mobile device.
  • the object of the present invention is to propose a device which makes the above-mentioned rotatable forks superfluous.
  • the object is solved by the characterizing part of claim 1.
  • Another advantage of a device according to the invention is that, due to its shape, the receiving device can generally carry the two parts securely, without the need for expensive clips rotatably mounted on the receiving device to hold the doctor device and the ink tray - as in EP 0 682 601 - are necessary.
  • Another advantage of the device mentioned is the fact that only one holding device is required to hold both the doctor device and the ink fountain.
  • the mobile exchange device When replacing the squeegee devices and the ink pan of printing presses, in which functional pairs of squeegee devices and ink tanks are mounted in relative proximity to one another, it is of great advantage if the mobile exchange device has a plurality of receiving devices, so that it is possible to have several during one exchange process Function pairs can be seen. This saves working time.
  • FIG. 1 shows an illustration of a flexographic printing machine in which the functional pairs to the right of the impression cylinder have just been removed with one embodiment of the device according to the invention

  • Fig. 9 shows the printing machine shown in Figure 6 from the side
  • a flexographic printing machine 9 is shown, in which the doctor devices and the ink troughs 7, which are located in Figure 1 to the right of the impression cylinder 12 of the flexographic printing machine, are being removed with the help of a mobile device 1, each from a doctor device 6 and an ink trough 7 formed functional pairs 10 are already on the receiving devices 4a to e, which in turn are carried by the frame 3 fixedly attached to the carriage 2.
  • the functional pairs were moved from the working position defined primarily by the receptacle for the ink pans 13 into the removal position 15, which is located in the illustrated exemplary embodiment on the folded-out removal forks 16. All five functional pairs 10 to the right of the impression cylinder 12 were then removed from the mobile in one operation Device 1 removed by raising the pick-up devices 4 of the mobile device on the frame 3. The mobile device had previously been brought into a position suitable for removing the functional pairs 10.
  • FIG. 1 now shows how the mobile device is moved out of the position suitable for removal
  • the functional pairs can be fed to a cleaning device in this way, for example.
  • the doctor devices 6 and ink pans 7 to the left of the impression cylinder 12 are still in their working position and the associated removal forks 16 are folded up shown in the state
  • FIG. 2 shows - like all other figures - the same embodiment of the invention, neither the flexographic printing machine 9 nor the functional pairs 10 being shown
  • the carriage 2 of the mobile device 1 is moved on rigid 17 and steerable rollers 18 by the machine operator 19.
  • the machine operator 19 can also transmit force or torque to the cable winch 8 by means of the hand crank 5.
  • This cable winch winds the cable 11, which via the deflection rollers 20 and 21 is connected to the guide carriage 22a of the uppermost receiving device 4a and thus the force necessary for the vertical movement of the receiving devices 4a to e is first transmitted to the guide carriage 22a of the uppermost receiving device.
  • FIG. 4a shows the elements of the mobile device 1 that are important for the vertical movement of the receiving devices, wherein the receiving devices 4a to e are in the lowered state.
  • Two lower bars 28 are connected at their lower ends with screws 29 to the guide carriage from which they are carried
  • the support rods 28 engage through a guide 32 in the bottom 31 of the guide carriage, which is located above the guide carriage to which they are firmly connected.
  • the support rods 28 protrude above the Bottom 31 of the guide carriage 22 a to d, which is located above the guide carriage 22b to e, with which they are firmly connected.
  • stops 30, which are at the upper ends of the Support rods 28 are attached, clearly recognizable These stops are equipped with a larger diameter than the support rods, so that they can not slide through the guides 32 of their support rods when moving up the receiving devices 4a to e, the winch 8 winds the rope 11
  • the rope becomes - as mentioned above - guided over the deflection rollers 20 and 21 to the guide carriage 22a of the receiving device 4a, to which it is attached at the fastening point 33.
  • the guide carriage 22a is raised until the guides 32 in the bottom 31 of the guide carriage 22a with the stops 30 of the support rods 28 of the guide carriage 22b come into contact, so that this second guide carriage is carried along with the further upward movement of the first guide carriage 22a
  • the winding movement of the cable winch can be continued until all receiving devices 4a to e are raised and the state shown in FIG. 4b is reached
  • FIGS. 4a and 4b also show the window 14, which makes it easier for the machine operator 19 to drive the car and in particular to position the car when the functional pairs 10 are replaced.
  • FIG. 5 shows the mobile device 1, the receiving devices 4 a to e shut down and loaded with function pairs 10 It is in any case advantageous to shut down the receiving devices as shown in FIG. 5 and in this way to lower the center of gravity of the mobile device 1 when the heavy functional pairs 10 are located on the receiving devices 4 a to e and the mobile device is driven
  • FIG. 6 shows a side view of a flexographic printing press which is equipped with another exemplary embodiment of the present invention.

  • Three of the four recording devices 4 on the left edge of the image already carry doctor devices 6.
  • the uppermost doctor devices 4 on both sides do not have such a device 6, so that it can clearly be seen that each of them is fixed with a fixing element 108.
  • the other three recording devices 4 of the right-hand image frame are loaded both with an ink tray 7 and with a doctor device 6.
  • the two stairs 102 can already be seen behind the receiving devices.
  • Figure 7 shows such a printing machine from above.
  • the uppermost pick-up device 4 on the left machine side is only loaded with a doctor device 7, while the pick-up device on the right-hand edge of the picture is loaded with both a trough 7 and with a doctor device 6.
  • FIGs 8 and 9 show side views of the machine. In this way it is clarified how the receiving devices are loaded and unloaded in the exemplary embodiments shown. This process takes place manually, the staircase 102, which is also attached to the flexographic printing machine 9, giving the machine operator 19 the opportunity to conveniently get to the working position of the ink tanks and squeegees.
  • the receiving devices 4 are shown in a lowered position. Ink tanks and doctor devices can be conveniently loaded and unloaded by the machine operator 19 standing on the floor.
  • the holding devices of all exemplary embodiments can also be used to exchange other organs of a printing press.
