Definitions
- the invention relates to a flexographic printing machine with several individually driven printing units for printing on a stretchable material web, in particular a plastic film web.
- the invention has for its object a flexographic printing machine of the beginning to create the type mentioned, which is accurate and correct Guaranteed print quality.
- the behavior of the material web or Plastic film web during its passage through the printing units of the Flexo printing machine responsive measuring device and a so computer-controlled evaluation and control device functionally connected, drive-controllable pull-out device provided.
- the measuring device can have at least one tension measuring roller acting on the plastic film web, for a setpoint is given.
- the specified setpoint and the by Glasmeßwalze measured values are compared and over the Pull-out device held. If the measured web tension becomes lower, the The pull-out device is driven faster, however, the tension becomes too great the speed of the pull-out device slows down and the elongation in the Plastic sheeting reduced.
- tension measuring roller instead of one tension measuring roller, several tension measuring rollers can also be used.
- the first tension measuring roller is on the outlet side arranged printing unit receiving area and a second tension measuring roller arranged between the first incoming printing unit and a preferred device.
- the measured tension values are compared and the pull-out device is regulated so that the tensile stress in the plastic film web is kept as constant as possible.
- the measuring device can have two incoming length and the outgoing length of the plastic film web Have measuring wheels that are connected to a differential value control device.
- the measuring wheels are in accordance with the incoming length and running length of the plastic film impulse to the Differential value control device delivered via the interposition of a Control amplifier, the drive unit of the trigger device is controlled accordingly.
- FIG. 1 shows a flexographic printing press designed as a stand flexographic printing press. This has an unwinding station 1, from which a material web to be printed, for example, a plastic sheet 2 unwound and along several for example, six inking units 3, 4, 5, 6, 7, 8 and finally not in one shown winding station is rolled up.
- a material web to be printed for example, a plastic sheet 2 unwound and along several for example, six inking units 3, 4, 5, 6, 7, 8 and finally not in one shown winding station is rolled up.
- the inking units are all identical and have the usually necessary Devices for printing such.
- the further design of the inking unit is also known and is therefore Adjustment spindles 12, 13 for the adjustment of the format cylinder and the anilox roller only indicated.
- Each inking unit is an individual electric motor drive with a servo motor assigned, the respective drive control unit via a master value system synchronizable with each other and with a common, computer-controlled Functional device for monitoring, control and regulation are connected.
- the flexographic printing machine shown in Figure 1 for printing on the plastic film web 2 is equipped with a tension measuring device.
- This points in the area of the first Printing unit 6 of the printing units 6, 7, 8 lying on the outlet side is a first one Gebmeßwalze 32 and in the area between the first printing unit 5 and one Preferred device 33 on the inlet side of the printing units 5, 4, 3 a second Gebmeßwalze 34 on.
- the tension measuring roller 34 gives the passage of the plastic film web 2 by the printing units from a tensile measurement value, which with the through the tension measuring roller 32nd measured tension value is compared.
- a drive not shown, becomes one behind the last one Printing unit 8 arranged pull-out device 35 with the interposition of a computer-controlled evaluation and control device correspondingly slower or driven faster.
- the Tension measuring device is replaced by a length measuring device.
- the latter has two Measuring wheels 36, 37, which are essentially in the same place as the tension measuring rollers are arranged in the embodiment according to FIG.
- the possibly occurring pulse difference, for. B. determined from positively evaluated entry impulses and negatively evaluated Run-out pulses, regulated to zero.
- the drive unit of the Pull-out device regulated accordingly.
- the measuring control device designed according to the invention is in front Start of an ongoing production operation by using a not stretchable film web, e.g. B. an aluminum band is calibrated or calibrated. In this way, z. B. conditional mechanical tolerances Inaccuracies easily due to a regular reset correct.
- the use of the tensile and Length measuring device can also be used, for example, for stretching the web and / or use filament drawing.
