Definitions

  • the present invention relates to a variable format rotary offset printer.
  • variable format offset rotary printers the format change was first made by replacing the printing cylinders.
  • the fixing devices being, for mechanical grooves (rigidity, absence of play, etc.), quite complicated, it is generally limited to the replacement of two cylinders, namely the plate cylinder and the blanket cylinder.
  • Two cassette systems are currently known, namely three-cylinder cassettes and two-cylinder cassettes.
  • the complete set of printing cylinders namely the plate cylinder, the blanket cylinder and the back pressure cylinder, is replaced with each change of format.
  • These three cylinders have the same diameter and they mesh with each other.
  • This system is universal because it allows print the front and back of a tablecloth without intermediate drying.
  • the back pressure cylinder is controlled and adapted to the format: there is therefore no macu privilege. It is understood, however, that this system is necessarily rher and therefore very limiting as regards the number of formats used.
  • format change systems by replacing cassettes are very disadvantageous by their rigidity of use.
  • the machines can only be designed for one of the two systems and if, for example, a three-cylinder system has been chosen, it is condemned, at each format change, unless complicated disassembly, to replace the three cylinders.
  • the present invention aims to remedy these drawbacks by providing a format change system with an integrated cassette, but which can be easily deposited if necessary, of particularly simple design and allowing the simple and rapid replacement of one, two or three printing cylinders as required, and which favors, by the arrangement of the cylinders, great simplicity, precision and reliability of the pressurization mechanism which is actuated by a single control without play.
  • this variable format rotary offset printer comprising a frame carrying, at its upper part, an inking device, a wetting device and at least one touch cylinder, and a cassette carrying the superimposed printing cylinders, namely an upper plate cylinder which can be pressed under the touch cylinder or cylinders, an intermediate blanket cylinder and a lower back pressure cylinder, these superimposed cylinders being tangent to each other in the printing position, and means for horizontally moving this cassette, is characterized in that the shaft of each of the three vertically superimposed printing cylinders journals, at each of its ends, in a slide mounted with vertical sliding between two vertical slides provided in an upright of the cassette, the slides housed in the same upright of the cassette are separated vertically from one another by intermediate shims of height corresponding to the distance between the horizontal shafts which depends on the printing format, the two lower slides on which the cylinder shaft spins dre lower back pressure being respectively supported on the upper ends of the rods of vertical cylinders carried by a horizontal cross member adjustable in height.
  • the horizontal crosspiece carrying the two vertical cylinders acting on the lower slides is adjustable in height by means of vertical rods moved up or down by a mechanism provided at the bottom of the cassette.
  • each upper slide in which the shaft of the plate cylinder revolves is applied against an upper block itself pressed against an upper stop provided on the frame of the machine and the three blocks have housings opening into their lower or upper horizontal faces and in which are arranged compression springs having different compression forces so that the spring housed between the lower wedge and the lower slide is the weakest, the spring disposed between the intermediate wedge and the grout intermediate bucket is the strongest and the spring disposed between the upper wedge and the upper slide exerts a force between those exerted by the previous two.
  • the rotary offset printer shown in the drawing comprises a frame 1 which consists of two parallel vertical uprights between which the various rotary printing cylinders extend and which is traversed longitudinally, from right to left, by the web 7 of a material on which printing is performed.
  • This frame 1 carries, at its upper part, in the usual manner, an inking device 2 and a wetting device 3, known in themselves, which are intended to apply layers of ink and of a solution respectively. wetting (generally water) on a plate or engraved upper cylinder 4.
  • This cylinder 4 of transverse axis is itself tangent to an intermediate blanket cylinder 5 which is located in turn above and tangent to a lower backpressure cylinder 6, the sheet of printing material 7 passing between the blanket 5 and backpressure cylinders 6.
  • the upper plate cylinder 4 is tangent to one or more touching cylinders ensuring the distribution of the ink and fountain solution.
  • the rotary printing press comprises two touch rollers 8 and 9 which receive the ink and the wetting solution, generally water, from the inking device 2 and the printing device respectively. wetting 3.
  • the rotary printer according to the invention comprises a cassette 11 on which are mounted the three printing cylinders 4, 5, 6 and which is movable horizontally, in the longitudinal direction, that is to say from the right towards the left in the drawing and vice versa.
  • the three printing cylinders 4, 5, 6 are simply filled vertically between two slides 12, 1 which extend vertically on each of the opposite uprights 14 of the cassette 11.
  • This cassette. It has a U shape and it has a lower horizontal core 15 connecting the bases of its two uprights 14.
  • the shafts 4a, 5a, 6a of the respective cylinders 4, 5, 6 are journalled, at their ends, in their respective slideways 16, 17, 18 which are mounted to slide vertically between the slides 12, 13 provided in each of the uprights 14 of the cassette 11.
  • Each of the upper slides 16 in which the shaft 4a of the upper plate cylinder 4 revolves is spaced from the intermediate slide 17, in which the shaft 5a of the blanket cylinder 5 revolves, by a wedge 19, and it is also spaced, by an immediately upper wedge 21, a stop 22 provided on the amount of the frame 1 of the device.
  • Each intermediate slide 17 is in turn kept spaced, by a wedge 23, from the corresponding lower slide 18, in which the shaft 6a of the counter-pressure cylinder 6 journals and which is in turn supported on the upper front face of the rod of a vertical cylinder 24.
  • This cylinder 24, preferably hydraulic, is carried by a lower crosspiece 25 which extends between the two uprights 14 of the cassette 11.
  • This crosspiece 25 can be adjusted in height, as a function. format, by means of a vertical rod 26, such as a screw, provided at each end of the cross member and whose vertical position can be adjusted by means of a known device designated as a whole by the reference 27.
  • the lengths of the shims 19, 23 are calculated with precision as a function of the format and they are such that under the effect of the two hydraulic cylinders 24 carried by the cross-member 25, the pressures between the cylinders 4, 5, 6, in the printing position , are correct.
  • the shims 21, 19 and 23 have respective housings 28, 29, 31 opening into their lower (or upper) horizontal faces and in which are housed compression springs 32, 33, 34, such as Belleville washers, the forces of which are carefully chosen. When the pressure of the jacks 24 is released, these springs separate the slides 16, 17, 18 from one another and offset the pressures between the cylinders 4, 5, 6 in this way without play.
  • compression springs 32, 33, 34 such as Belleville washers
  • the spring 32 which is disposed between the upper wedge 21 and the upper slide 16, is compressed for an average pressure of the jack 24, which allows, in a second start-up phase, the inking of the plate of the cylinder 4, without transferring the printing onto the blanket cylinder 5.
  • the final pressurization of the jack 24 finally causes the compression of the third spring 33, disposed between the intermediate shim 19 and the intermediate slide 17, which allows the transfer of the printing to the blanket cylinder 5 then from the latter to the web. of paper 7.
  • the intermediate shim 6 is slightly shorter, by a few hundredths of a millimeter, than the theoretical length.
  • the pressure shift operation can be done in two stages. First of all, there is a change from high pressure to low pressure in each of the jacks 24, which decompresses the springs 33 and 32.
  • the plate cylinder 4 moves away from the touching cylinders 8, 9 and it remains inked, this which protects it from outside agents.
  • the blanket cylinder 5 moves away from the plate cylinder 4 and no longer transfers the printing; on the other hand, it still remains in contact with the paper sheet 7 since the spring 34 is compressed, which makes it possible to discharge it and consequently to simplify the washing operations thereafter.
  • the final offset of the pressures is obtained by the total release of the pressure in each jack 24 and the decompression of each of the springs 34.
  • the rotary drive control is fixed and it is centered on the axis of the touch cylinder 8. It transmits the movement to the three printing cylinders by gears, when they are put in place according to the format by the screws 26 .
  • the integrated cassette 11 can be moved horizontally as a whole, to the left, in the position indicated in phantom in the drawing, by means of horizontal and longitudinal screws 35 controlled by a transverse shaft 36.
  • the offset position indicated in phantom corresponds disassembly of the various printing cylinders.
  • the slides 12, 13 lead to an opening in the upper part of the cassette 11, which makes it easy to extract the cylinders, using the vertical screws 26 as a lifting cylinder.
