Definitions

  • the present invention relates to a station for loading the paper roll carrier of rotogravure printing machines with paper rolls.
  • roller speeds of 50,000 revolutions per hour are achieved, which correspond to a speed of the paper web to be printed in the order of magnitude of 12-14 m / s.
  • the essential widths of the paper web to be printed as well as these high speeds lead to new problems which concern the change of the paper roll, ie the replacement of the exhausted paper roll with a new paper roll.
  • Such paper rolls actually have a diameter that is larger than 1 m and a weight of approximately 25 hundredweights. With a printing or unwinding speed of the paper roll of 12 m / s, the result is that the roll is exhausted in a relatively short time of 15-20 minutes.
  • the operators who are responsible for the mode of operation of the paper roll trap monitor carry out a whole series of work steps for exchanging the paper rolls, which extend from the infeed of the paper roll near the paper roll holder to its handling and arrangement on the paper roll holder, whereby all these work steps are to be carried out with great accuracy then, at full print speed, the automatic adhesive connection known per se between the paper web end section of the exhausted paper roll and the paper web start section of the supplied new paper roll can be realized.
  • the time required to replace the paper roll is estimated to be in the order of magnitude of approx. 10 - 12 minutes, whereby this work process entails the need for several operators to be present at the same time and consists of the following work steps:
  • the present invention has for its object to produce a station for loading the paper roll carrier of rotogravure printing presses with paper rolls, which is capable of enabling a roll change that takes place in a flawless, fast and reliable manner and without any physical effort to handle the paper roll that the roll change operation can be carried out by a single operator.
  • the station for loading the paper roll of the type mentioned should enable the paper roll change in an extremely reliable manner in such a way that this process for exchanging the paper rolls is automated and the decommissioning, which can be attributed to a breakage of the paper, is canceled or can be reduced to a minimum.
  • the paper roll change sequence can only be controlled by an operator, even if it is a very large paper roll, for example with a weight of approximately 25 hundredweights or more and with a width of over 2 m of the endless paper webs.
  • the proposed station is embedded or accommodated below the floor surface, so that its space requirement immediately in front of the paper roll support device is not a disadvantageous problem and in no way prevents the paper rolls from entering the area near the same station.
  • the proposed station can manipulate or position any supplied paper roll, regardless of its diameter and width and without any prior intervention to adapt the station itself.
  • FIG. 1, 1 denotes the paper roll carrier of a type known per se, which is arranged in front of a rotogravure printing machine, which is not shown in detail.
  • the paper roll carrier 1 has a support frame 2 with side walls 3 for supporting a shaft 4.
  • the shaft 4 can be driven by a motor transmission 5.
  • Two cheeks 6 are laterally attached to the shaft 4, each of which forms two opposing arms 6A, 6B.
  • the arms 6A, 6B are each provided with a widening and tensioning device 7, known per se for short, “clamping jaws”, which are preferably designed in the manner of a compressed air device and, in the example shown, can be controlled by a crank handwheel 8.
  • the paper roll shown in the course of the unwinding process is designated 9 and lies in its position facing the printing press on the arms 6A.
  • a new paper roll, designated 10 is to be placed, which has a core 11.
  • the paper roll carrier in its entirety, as well as the clamping jaws and other components of the same are of a known type and are therefore not explained in more detail below.
  • the cheeks 6 of the paper roll carrier 1 are each rotated through 180 ° when changing the paper roll, the ends of the free arms 6B being in a lower position than the ends of the arms 6A in order to apply the new paper roll 10 facilitate.
  • the new paper roll 10 is pushed or pulled close to the paper roll carrier 1 by at least two operating men.
  • Movable bogies 12 fed which move along in a bottom groove 13 or on a hanging rail, not shown.
  • the station for loading the paper roll carrier 1 with paper rolls 10 has a design and a method of operation which will be explained in more detail below.
  • the station is generally designated 14 and is recorded below the floor surface 15.
  • 15a is a cover plate or cover platform.
  • cover sheets can be provided as desired.
  • the station 14 comprises a pair of support rollers 16 for receiving and holding the paper roll 10, the support rollers 16 having bearing ends 17 which are recessed with respect to the floor surface.
  • Fig. 2 16 a box-shaped protective housings, for example made of sheet metal, are designated.
  • the recessed bearing ends 17 are received in bearing sleeves 18, the lower support block 19 of which is fastened to a column 20, for example by welded flanges opposed to one another.
  • the stands 20 are attached to a frame 21 at the bottom.
  • a protrusion 22 or preferably two protrusions 22 each protrude from each of the two opposite sides thereof, each of which has a nut thread 25 which is firmly connected to the same.
  • Each nut thread 23 is screwed onto its own screw spindle 24, which, as can be seen in FIG. 3, is rotatably supported at the bottom on a bearing 25 which is fixedly connected to a drive 26 explained below.
  • a motor gear 27 and chain drives with associated toothed wheels, which are designated by 28, serve to rotate the screw spindle 24.
  • this motor gear 27 therefore, the nut thread 23 and accordingly the support rollers 16 are moved up and down.
  • the structure interposed between nut threads 23 and these support rollers 16 thus forms a supporting structure for this support roller and is designated 29 overall.
  • the running gear 6 also comprises a lower frame, designated 30, which has stands 31, through which roller wheels 3, which can slide along longitudinal rails 34, are carried by rigid parts 32 connected in between. These longitudinal rails 34 are anchored on the longitudinal walls of the pit 35 which receives the station 14. To move the drive 26, a longitudinal rack 36 is attached to each of the longitudinal rails 34, in each of which a pinion 37 engages, which is fastened to a shaft 38 driven by a motor gear 39, as is clearly shown in FIGS. 3, 4. End stops for the horizontal movement are designated by 40, 41, which are each assigned to their motor gear 39 in a manner known per se and not explained in more detail.
  • the station according to the invention also has a sensor 42 for transverse centering of the paper roll 10 to the paper roll carrier 1, a photocell 43 for precisely holding the arms 6A at the end of the stroke of the rotation of the cheeks 6 of the paper roll carrier 1, and a further photocell 44 which is arranged on the cheeks 48 and serves to determine the alignment between the axis or light beam of this photocell and the central axis 11a of the paper roll 10.
  • the introduction of the paper roll 10 into the station 14 takes place, for. B. by a sliding in the groove 13 trolley 12, the paper roll 10 on the pair of support rollers 16 of the station is put on.
  • the precise transverse positioning of the paper roll 10 to the cheeks 6 of the paper roll carrier 1 is set by the centering or positioning sensor 42. These cheeks are then rotated by a fixed angular value, which is determined by the photocell 43 arranged on the axis of the shaft 4 of the paper roll carrier 1.
  • a forward stroke of the support rollers 16 of the stage 14 in the direction of the paper roll carrier can take place until the stop 40 is reached.
  • This forward stroke brings the central axis 11a of the paper roll 10 into the vertical plane, where the axis of the photocell 44 lies.
  • a short upward stroke of the paper roll 10 can take place in order to bring the axis of the above photocell 44 into collimation with the beginning of the cavity present in the core 11, this beginning of the core cavity positioning the central axis 11a of the paper roll 10 in a horizontal plane, in which is the central axis of the jaws 7, causes.
  • the loading movement of the paper roll is therefore essentially divided into two partial movements, namely in a horizontal displacement movement and in an upward movement of the support rolls 16 or the paper roll 10, the upward movement being realized by the lifting means 23, 24, 27, 28 and the advancing movement by the translating means 33, 34, 36, 37, 38 and 39.
  • the support rollers 16 are therefore held in a support frame 29, to which the above lifting means are assigned and in turn are mounted in a running gear, ie in a movable frame, these structures being incorporated into one another: this results in decisive advantages with regard to the limited space requirement.
