Definitions

  • the invention relates to a screen printing machine with at least one adjustable screen with an application device, such as a doctor blade with a counter pressure device, e.g. Impression cylinder or the like, as well as means of transport for web guiding and devices for reading registration marks or the like for multi-color printing.
  • an application device such as a doctor blade with a counter pressure device, e.g. Impression cylinder or the like, as well as means of transport for web guiding and devices for reading registration marks or the like for multi-color printing.
  • Such devices are known per se, it is initially irrelevant whether the multi-color printing takes place directly in succession in the machine, or whether the web is first rolled up and only later fed to a subsequent print, the former method being more advantageous.
  • the registration marks or the like are read and in the known machines the web guide is adjusted according to the result, so that it is ensured that the subsequent print is placed exactly. This is done in order to prevent marginal displacements that make inaccurate, disturbing, differently colored edges appear in multicolor printing.
  • the web feed means must be controlled precisely in the previously known machines, that is to say the web is held back or is fed in at an accelerated rate, depending on the correction request.
  • the invention is therefore based on the object of making a correction possible without the imponderabilities of the web having a disruptive effect and only the respective printing result counting.
  • the invention consists in the fact that the screen is displaceably mounted with a frame and servomotors are provided for regulating the same in the longitudinal and transverse directions, the servomotors in turn being electrically connected to at least one surveillance camera for the registration mark reading, the pulse generator via a computer for the servomotors controls.
  • the sieve with frame can lie in a carriage that is controlled accordingly.
  • a plurality of screen arrangements are arranged one behind the other in a machine, with at least the printing units following the first printing unit separately, each with one or more, in the inlet and / or outlet of the web, the registration marks or edge-reading surveillance cameras and are each connected to a number of computer-controlled servomotors for setting the sieve or the sieves or the sled.
  • the entire device can work variably, depending on which computer system is used and which accuracy is desired in the first order, or how many color orders are run in succession.
  • the printing result can be achieved in an accuracy range that is far away from known results. Uncertainties from the transport of goods and from the goods themselves are excluded, or compensated or compensated for.
  • difference value means the length deviation between the original and the actual print. This is entered into the computer in the + or - direction.
  • the pulse generator is used to evenly distribute the difference value over the entire print image. For example, if the difference in the plus is 0.10 and the pulse generator delivers 10 pulses for a print image, each correction is 0.01 mm / pulse.
  • the invention is seen in the fully automatic print registration, which adjusts two or more templates to the positional accuracy achieved in the template production for the respective print job.
  • the fully automatic registration in the machine 1 shown should be able to apply at least two colors to one another in such a way that the register marks used are accurate to e.g. Stand +/- 0.05mm to each other. If no register marks are used, which may happen in special cases, the single point query should not show any major difference.
  • the position of the first printing ink must be recognized and the screen of the color to be applied next corrected before the further printing ink is applied.
  • the printing station 2 shown, in the screen printing machine 1 shown only partially in FIG. 1, preferably has two cameras 5, 5 'lying parallel to one another in the feed of the web 3, below the screen 4. In the exemplary embodiment shown in FIG. 1, these lie in front of an impression cylinder 6 which has suction holes 16.
  • a sieve frame 4 ' carries the sieve 4 and lies in a longitudinally and transversely movable carriage 44. This carriage 44 is in turn mounted in a support frame 40 which carries the servo motors 9, 9', 9 '' which move the carriage 44.
  • connection between screen printing machine 1 and computer 8 can take place via cable 18 if one does not prefer a radio connection.
  • the mounting of the screen template 4 with its screen frame 4 ' is shown in FIG. 1, the screen or template frame 4' being in turn fitted into a carriage 44 which bears against the servomotors 9, 9 ', 9''.
  • the servomotors 9, 9 ', 9' 'are designed as stepper motors.
  • the number of steps / revolution can e.g. Be 1000 / 1U, so that an exact correction of the position of the screen template can be made in the longitudinal and / or transverse direction.
  • the actuators or stepper motors work precisely.
  • the template frame 4 ' is inserted into the carriage 44.
  • Springs 11 ensure that a cross bar 41 of the slide 44 is pressed evenly onto the servomotors. This is a guarantee that the work of the servomotors, which are designed as stepper motors, is transferred exactly to the stencil and that their position during printing is guaranteed.
  • the area "a" in the screen printing stencil 4 drawn corresponds to the actual printing, for example 299 mm.
  • the template is 1 mm larger, for example, 300 mm and thus the area "b" is the processing error or the "difference value" of 1 mm. This value is measured and entered once.
  • the pressure cylinder 6 is connected to a pulse generator 16 which emits, for example, 1 pulse / 10 mm.
  • Such additional movements with this precision are only possible via the computer or computer control. This is the default input for each print sequence and is important, especially if high-quality prints, such as printed circuit boards, are to be printed, which often happens.
  • the stencil frame 4 shows the mounting of the screen template 4 with its frame 4 'and the setting frame or slide 44.
  • the stencil frame 4 'lies in the carriage 44 and by moving it by means of the actuating or stepping motors 9, 9', 9 '', the lateral adjustment or displacement and also the forward and resetting are effected, the stepping motors , as mentioned, can be controlled by the computer 8.
  • This is supplied with data even by the camera pairs 5.5 'and 7.7'. The data is thus determined before the run-in and after the paint application. Subordinate use is also possible, but not so advantageous.
  • At the first print only the registration marks are checked and the difference value is taken into account.
  • the second and subsequent pressure is carried out in the stations by the displacement of the carriage in which the templates are located, based on the camera values determined, exactly by the servomotors 9, 9 ', 9''controlled by the computer 8. Possibly. Errors are discovered immediately and avoided immediately without rejects being produced continuously.
  • This idea of fully automatic print registration can be realized on single-station printers where the web is run several times and also in multi-color screen printing machines. If two cameras 5.5 'and 7.7' are shown in the example, this is very advantageous; if necessary, one camera in the inlet leg and one in the outlet leg of the web might be sufficient, but then the detection of any angular errors is missing.
  • 5 shows a drive diagram for three stations.
  • a push rod 13 moved via a rocker arm 12 takes all the desired stations evenly, in each station the position of the template is separated from the cameras and the computer 8. regulated about the displacement of the carriage 44.
  • the idea of the invention is not limited to the exemplary embodiment shown, so variations are conceivable and possible.
  • the screen printing machine can have only one station through which it is driven several times, or a number of stations, optionally with intermediate drying. That must be left to the circumstances. It is advantageous to equip each station with the monitoring device described, or according to the circumstances.
  • the computer or computer can also be freely selected, with or without screens 8 ′, 8 ′′, and with or without a display 81, which monitors control of the activation of the cameras and the motors, or monitors other functions of the machine.
