Definitions
- the invention relates, on the one hand, to a method and, on the other hand, to a device for the precise positioning of the inking station or stations, in particular printing cylinders such as printing cylinders and screened cylinders of a flexographic printing machine, independent positioning of the thickness tolerances of the plates and their adhesive supports, the thicknesses of the materials to be printed and the mechanical play of transmission of the positioning means.
- printing cylinders such as printing cylinders and screened cylinders of a flexographic printing machine
- control means “step by step” allow movement relative to the slide of the general frame.
- control means by “step by step” generally include a reference point corresponding to the position of the maximum clearance of the slide and the support. This reference point is taken into account by the control means for positioning the cylinders with one another as a function of the development of the cliché cylinder.
- the cylinders of the inking stations are put into and / or out of printing as a function of a number of steps of the predetermined and invariable adjustment screws whatever the development of the plate cylinder, the number of steps determining the length of stroke of engagement or disengagement of the slide and the support.
- French patent No. 2,107,420 discloses an automatic positioning device for a printing press. According to this patent, it is an apparatus which makes it possible to position the various cylinders used in the composition of a printing machine, from a central control station.
- the device is entirely made up of analog circuits which, by comparison of potential between adjustable resistors and reaction potentiometers, make it possible to correct errors and thus ensure efficient positioning of the cylinders.
- French patent No. 2,101,415 discloses a method and device for the remote control of adjustment and drive members on printing machines.
- the different cylinders of the inking devices of the printing machines are coupled to devices driven by stepping motors which make it possible to adjust them.
- the control device for the different motors has an impulse counter and an inverter which make it possible to preset the rotations of the stepping motors and, consequently, the members driven by them.
- the flexographic printing machine comprises a counterpressure cylinder 1 serving as a support for the material to be printed 2.
- This counterpressure cylinder 1 is placed between two frames 3, 4 arranged on either side of the longitudinal axis of the printer and, for a better understanding of the description, these frames 3, 4 will be called right frame 3, left frame 4, seen in the direction of unwinding of the material to be printed 2.
- the different motor elements 13, 14 and 31, 32 are controlled by means of a digital control unit 41 which solicits the motors 13, 14 and 31, 32 according to the known principle of "pitch".
- Each "step” of the motors 13, 14 and 31, 32 corresponds to a determined rotation of the adjusting screws 15, 16 and 33, 34, therefore to a precise displacement and positioning of the slides 8, 9 and the supports 24, 25 by relative to the frames 3, 4, therefore relative to the stops 19, 20 and 39, 40.
- a format 42 display is carried out.
- This format display 42 is decoded and transcoded in the digital control unit 41.
- the digital control unit 41 sends the "step" pulses to the driving elements. 13, 14 and 31, 32 by means of digital control assemblies 43, 44 and 45, 46 specific to each positioning motor element 13, 14 and 31, 32.
- the pulses are counted in a counter inherent to the digital control unit 41 and digital control units 43 to 46 until equal to the number of pulses decoded and transcoded from the display 42.
- digital digital control unit 41 is supplemented by digital correction display units 47, 48, 49, 50.
- the digital correction display 47 relates to the automatic taking into account, by the digital control unit 41 acting on the driving elements 13, 14 and 31, 32, of the mechanical clearances or tolerances in the transmissions of movement between the driving elements 13 , 14 and 31, 32 and the slides 8, 9 and supports 24, 25. Indeed, any mechanical transmission system is subject to a certain play. Thus, between a movement of advance and retreat of the slides 8, 9 and / or the supports 24, 25 required during the final corrections of the positioning adjustments of each adjusting screw 15, 16 and 33, 34, it is necessary to make up for the mechanical play in the system for transforming the movement of the driving elements 13, 14, 31, 32 in linear movement of the slides 8, 9 and / or the supports 24, 25.
- the digital control assemblies 43 to 46 of the motor elements 13, 14, 31, 32 take into account the manual corrections or pulses delivered by the operator and allow the final positioning of the slides 8, 9 and the supports 24, 25.
- the display 47 of the mechanical transmission clearances relates to the four positioning assemblies: adjusting screws 15, 16, 33, 34 and motor elements 13, 14, 31, 32 constituting the inking station 7. For this reason, the display 47 can be subdivided into four displays 47 1 , 47 2 , 47 3 , 47 4 to allow the actual play of each positioning assembly to be taken into account. In this case, the displays 47 1 , 47 2 , 47 3 , 47 4 are applied directly to the digital control assemblies 43-46 of each positioning motor element 13, 14, 31, 32 of an inking station 7.
- correction displays 48 and 50 are also made individually for each inking station 7.
- the correction display 48 applies to the positioning of the slides 8, 9 and the supports 24, 25.
- L 'display 50 only concerns the supports 24, 25, therefore consequently only the screws 33, 34.
- FIG. 5 shows diagrammatically the principle of FIG. 3 applied to a flexographic printing machine comprising several inking stations 7 1 , 7 2 ' 7 3' ...
- the same digital control unit 41 is used for the establishment of the information and their transmission to the four mo elements ters 13, 14, 31, 32 of each inking station 7 1 , 7 2 , 7 3 ....
- a set of commissioning 61 1 , 61 2 , 61 3 , 61 4 , 61 5 , 61 6 serving for selecting the inking station (s) 7 1 , 7 2 , 7 3 , 7 4 , 7 5 , 7 6 must take into account the information supplied by the digital control unit 41 for the positioning of the ink stations - g e 7 1 , 7 2 , 7 3 ... having to perform a certain print job.
- the advance pulse donors 51, 52, 53, 54 or the reverse pulse 55, 56, 57, 58 are arranged near the inking stations 7 1 , 7 2 , 7 3 , 7 4 , 7 5 , 7 6 ....
- the additional pulse donors 51, 52, 53, 54, 55, 56, 57, 58 for each inking station 7 1 , 7 2 , 7 3 , 7 4 , 7 5 , 7 6 are arranged at other places on the flexographic printer and, more particularly, near an observation and viewing station for the material to be printed 2.
