Definitions

  • the present invention relates to variable format web offset printing.
  • each printed format can contain one or more printing patterns, each corresponding to future packaging.
  • a print could correspond to a cylinder circumference or a print format (minus the dead zone used for fixing the sheets and blankets); on the other hand, in the case of liquid boxes, it will take several printing patterns to go around the cylinder.
  • the object of the present invention is to minimize the manpower and the time necessary for the unloading-loading of the printing cylinders during a format change in an offset printing machine.
  • the offset printing machine represented in FIG. 2 therefore comprises, in a manner similar to FIG. 1 described above, an upper PP plate cylinder, an intermediate PB blanket cylinder, a lower CC counter cylinder, a unit inking E with its inkwell E1 and its rollers E2-E4, a wetting unit M with its tank M1 and its rollers M2-M4, a washing module L (not shown in FIG. 1) of the cylinder PB.
  • the machine comprises a fixed lower part or frame Ba and a vertically movable upper part, called the CE inking cassette.
  • the two cylinders PP and CC are mounted for rotation on the first end of a rocking lever 8, respectively 8 ', the second end of which is mounted for rotation along a horizontal axis 81, 81' with fixed prestressed bearings on the Ba frame.
  • the cylinder PB is mounted fixed at each of its ends on the frame Ba. In this way, it is possible, depending on the angular position of the tilting levers 8, 8 ′, to put in the working position PP and CC cylinders of different diameters in relation to the length of the format to be printed.
  • the cylinders PP, PB and CC shown in solid lines correspond to the maximum format, and those in broken lines to the minimum format.
  • the inking unit E and the wetting unit M with their elements E1-E4, respectively M1-M4, are mounted directly on the inking cassette CE.
  • the distributing rollers E3 or M3 those shown in thick lines are strolls.
  • All touch rollers E4 or M4 are mounted on tilting levers. From FIG. 2, it is also possible to see that, thanks to the vertical mobility of the cassette CE and to the touching rollers E4 or M bascul mounted on tilting levers, the inking units E and mooring M can always be that is to say whatever the size of the cylinders PP, PB and CC within the framework of the maximum and minimum formats provided, occupy a position which allows them to fulfill their function of inking, or wetting.
  • the washing module L it is horizontally movable to be adapted to the format of the cylinder PB.
  • FIG. 3 shows the instant when the cassette CE is at the maximum high point so that, even in the case of the maximum format of the cylinders PB and PP (here the cylinder CC has no influence), the cylinder PP is completely free from the touch rollers E4 and M4. Given, as will be seen later, that the purpose of this clearance is to make it easier to change the cylinders, it has been found that in the highest position of the CE cassette, a distance of at least 50 cm should be provided between the PP cylinder and the nearest E4 or M4 touch roller.
  • FIG. 4 four printing groups G1-G4, each of which corresponds to a color of the offset printing, are traversed by the strip F in the right-left direction, it being understood that the other left-right direction can also be expected.
  • the first group G1 is intended to print the back of the strip F and the three following groups G2-G4 the front.
  • guide rollers R2 for driving the strip F, which arrives from the right, over and behind the group G1 which it then crosses in the left-right direction. so that its front is printed by the cylinder PB.
  • rollers R3 then deflect 180 ° downwards the strip F which leaves the first group G1, to orient it again in the right-left direction so as to bring it through the base of the first group G1, in the direction of the guide rollers R4 provided on the second group G2. Rollers R4 are arranged so as to bring the strip F to the level and in the direction of the cylinder PB of group G2. Then, the band F horizontally crosses the three groups G2-G4. At the exit from the machine, rollers R5 guide the strip F to a next working machine, for example for cutting the strip into sheets.
  • the offset machine can also be provided with a drying station S either at the exit of the strip F of the first group G1 to dry the back, or at the exit of the last group G4 to dry the front, or still between groups, for partial drying.
  • each printing unit G1-G4 On each side of the strip F and on the frame Ba of each printing unit G1-G4 are provided vertical guides 2 intended to support and guide the arms of a loading-unloading system of the cylinders PP, PB, CC.
  • a free space is provided for the installation of a carriage 3 on which the three replacement printing cylinders PP ', PB' and CC 'can be placed, that is to say say for a new job, as shown in Figure 4.
  • the carriage 3 has the function of transporting, from a storage location, the three reserve cylinders PP ', PB', CC ' and to place them perpendicular to the strip and near the PP, PB and CC cylinders already present.
  • the carriage 3 (FIG. 7) consists of a base 31 of length approximately equal to that of the printing cylinders and of a vertical upright 32 connected to one end of the base 31.
  • the base 31 is equipped four swivel wheels 33 to allow autonomous movement of the carriage 3.

  • the vertical arrangement of the horizontal supports 35a-35c is such that the printing tape F can, along a horizontal path, pass between the lower support 35a and the intermediate support 35b and arrive between the two cylinders PB and CC.
  • a free space is provided between the lower support 35a and the base 31, for the passage of the strip F in the case, for example, of the group G1 of FIG. 4.
  • downstream of each group G1-G4 can be set up a carriage 3 by displacement of the latter perpendicular to the direction of travel of the strip F.
  • FIG. 7 being given that it is not necessary to provide a band passage F between the two upper 35c and intermediate 35b supports, the free ends of the latter two are connected to each other, for reasons of rigidity, by a vertical cross-member 38.

  • the lower ends of the two ball screws 23 are interconnected by transmission means (not shown) and driven simultaneously by the same motor N1.
  • the ball screw 23 is engaged with a corresponding nut 25a provided in the mobile support 25, so as to move the latter by rotation of the ball screw 23. In this way, a simultaneous and identical displacement and positioning are obtained for the two movable supports 25.
  • each arm 26 The pivoting of each arm 26 around the horizontal axis of the corresponding support 25 is obtained by means of a spline shaft 24 whose upper and lower ends are also mounted in free rotation, by means of the bearings 22a, respectively 22c, on the frame Ba of the group G2.
  • the lower ends of the two splined shafts 24 are connected together by transmission means (not shown) in order to be able to drive them in rotation, simultaneously and at the same speed, by means of a single motor N2.

  • each clamp 26a can be engaged with a part released from the central shaft 14 of the cylinders PP, PB and CC; means must even be provided for releasing this central shaft 14 with respect to its rotation bearing mounted on the frame Ba of the group, these means possibly being roughly similar to those already used to date to allow a change format of such cylinders.
  • the fact that the cylinders PP and CC are mounted in the group G2 on tilting levers 8, respectively 8 ′ also makes it possible to keep them sufficiently distant from the fixed cylinder PB (even in the case of a large format ) to make unloading-loading easier.
  • sequences will be chosen automatically by checking the presence of the elements when the carriage has been inserted. This control will be done by read heads, proximity switches or similar means.
