Definitions

  • the invention relates to a method for controlling a screen printing cylinder machine, wherein during the printing process a printing cylinder receiving the printing material and driven by a drive motor and a screening carriage traveling over it are moved with synchronized speed with a squeegee lowered onto the screen template.
  • the invention further relates to a screen printing cylinder machine with a printing cylinder receiving the printing material and driven by a drive motor, a screen carriage traveling over it, a squeegee which can be lowered onto the screen stencil and a device for synchronizing the movement of the printing cylinder and the screen frame during the printing process, which according to the above described method works.
  • the first method makes use of a so-called oscillating cylinder, which has a single toothed wheel on each end face, which is permanently in engagement with the toothed rack attached to the corresponding side of the screening carriage. After the printing process, the cylinder reverses to the initial position in which it receives the next print item, with the printing process immediately starting again.
  • a disadvantage of this method is that the oscillating cylinder changes from a rotational movement into the opposite direction without a rest, so that the newly fed printing material must be grasped by the printing cylinder immediately. It happens that the print material is not placed correctly or not optimally on the printing cylinder, which affects the print quality.
  • the second known method tries to avoid this disadvantage in that the synchronization between the printing cylinder and the trolley takes place during the forward and return through two gears on each end of the printing cylinder.
  • the first gearwheel engages with the toothed rack arranged on the relevant side of the screening carriage during the printing process (advance).
  • this toothed wheel and the toothed rack are decoupled in that the teeth are cut out by milling at a corresponding point on the toothed wheel.
  • the rack can run back freely through the stopped gear.
  • the return of the screening carriage is effected by a second gear, which is brought into engagement with the rack arranged on the relevant side of the screening carriage during the return. During the return, the first gear is held in place by a mechanical device.
  • the first gear After returning, the first gear is rotated again and brought into engagement with the rack of the screening carriage, whereby a new printing process begins.
  • the two gears are driven by a drive motor. Since the printing cylinder coupled to the first gearwheel always rotates in the same direction and stops during the return of the screening carriage, the printed matter can be applied to the printing cylinder for a sufficient period of time at a corresponding printing speed.
  • a disadvantage of the second method is the technically very complex mechanical synchronization of the two gears. This also leads to a correspondingly high one Repair requirement and relatively frequent maintenance of the screen printing cylinder machine.
  • the print speed is limited by the mechanics. Each increase in the printing speed also leads to a reduction in the downtime of the printing cylinder during the return of the screen carriage, which impairs the exact application of the printing material to the printing cylinder. Overall, the economy of the two methods is very unsatisfactory due to the disadvantages described.
  • the present invention has for its object to provide a method for controlling a screen printing cylinder machine, which is characterized by high print quality and great economy through simple technical means and high printing speeds. It is a further object of the present invention to provide a corresponding screen printing cylinder machine with the advantages mentioned above.
  • the printing cylinder and the screening carriage are driven independently of one another and the drive motor of the screening carriage is decoupled from the movement of the screening carriage synchronized with the printing cylinder during the printing process and then drives the screening carriage during the return, the printing cylinder being brought to a standstill before completion of the return.
  • the drive motor of the screening carriage is brought to a standstill during the printing process and the drive motor of the printing cylinder before the return of the screening carriage has ended.
  • the drive motor of the printing cylinder which is at a standstill before the return has ended, holds the printing cylinder in this position during this time in which the printing material is applied.
  • the printing cylinder and the screen carriage are driven independently of one another, data for setting the printing path and the printing speed are programmed into an electronic control device, stored therein and processed into control signals for the drives and the respective movement positions of the printing cylinder and of the screen carriage during the printing process are determined by position measuring systems and further processed in the electronic control device for regulating the control signals.
  • the above-mentioned advantages are also achieved with this method according to the invention.
  • the printing path covered by the screen carriage during the printing process corresponds to a full revolution of the printing cylinder and is adapted to a maximum format size of the printed matter. Therefore, the printing agent is spread by the flood doctor over the entire screen area corresponding to the maximum printing format. The one in the spread of the printing medium on the screen surface evaporation of the solvents contained in the printing medium leads to environmental pollution.
  • the consistency of the printing medium also changes, so that it has to be mixed more frequently in order to ensure a constant print quality. Since the squeegee travels the maximum print format with every printing process, it is also exposed to a corresponding load and wear.
  • the pressure doctor blade and the flood doctor blade are also controlled as a function of the moving position of the screening carriage. This enables a more precise and easier control of the doctor blade application point, regardless of the printing speed.
  • the method according to the invention offers the greatest possible flexibility with regard to the printing process.
  • a screen printing cylinder machine of the type mentioned at the outset it is provided according to the first solution that two mutually independent drive motors for driving the printing cylinder during the printing process and for driving the screening carriage during the return, a device with which the drive motor of the screening carriage during the printing process (advance of Screening carriage) can be decoupled from the movement of the screening carriage synchronized with the printing cylinder, and a device with which the printing cylinder can be brought to a standstill before the return of the screening carriage has ended can be used.
  • the drive motor of the screening carriage is coupled to the latter via a freewheel, which decouples the drive motor from the screening carriage in the direction of rotation of the motor shaft, which corresponds to the advance of the screening carriage during the printing process, and the drive motor of the printing cylinder is coupled to it via a freewheel, which decouples the drive motor from the pressure cylinder in the direction of rotation of the motor shaft, which corresponds to the return of the screening carriage.
  • the first freewheel can e.g. are on the hub of the drive motor of the screening carriage and be designed as an industrial freewheel.
  • the second freewheel can in each case on the two gear wheels of the impression cylinder.
  • a screen printing machine of the type mentioned at the outset that two mutually independent drive motors for the printing cylinder and the screen carriage and an electronic control device are provided which have an input unit for data for setting the printing path and the printing speed, and an associated programmable memory Computing unit for processing the data in control signals for the drive motors and two control units assigned to the drive motors, which are connected to position measuring systems for the printing cylinder and the screening carriage.
  • rotary pulse encoders are provided as displacement measuring systems, which are arranged on the pressure cylinder or a drive wheel for the screening carriage.
  • glass measuring rods can also be used instead of the rotary pulse encoder.
  • any other suitable measuring system can be considered.
  • the screen printing cylinder machine shown schematically there essentially consists of a printing cylinder 1 receiving the material to be printed, a screen carriage 2 traveling over it, a printing squeegee 3 which can be lowered onto the screen stencil and which is raised in the return shown in FIG. 1, and a flood knife 4 lowered during the return.
  • the pressure cylinder 1 is connected to a drive 7 via a coaxial pulley 5 connected to it and a toothed belt 6.
  • the pulley 5 has a coaxial rotary pulse generator, which serves as a path measuring system 8 for the arc angle of the printing cylinder which has been traveled from the initial position.
  • the sieve carriage 2 runs, reversibly moved by a toothed belt 9, over the pressure cylinder 1.
  • the toothed belt 9 is driven in its reversing movement by a drive wheel 10 and runs via a pulley 11.
  • the drive wheel 10 has a coaxial rotary pulse generator, which acts as a measuring system 12 serves for the distance traveled by the screening carriage 2 from the initial position.

  • the two drive motors 17 and 18 are controlled as follows:
  • the data for the print path and the print speed are read into the computing unit 13 via a keyboard and stored therein.
  • the computing unit 13 processes the data into control signals for the drive motors 17 and 18.
  • the control signals are fed to the corresponding control units 15 and 16, where they are converted into the corresponding currents and voltages for the drive motors 17 and 18.
  • the printing cylinder 1 and the screen carriage 2 are at rest.

  • the squeegee 3 is lowered onto the screen template of the screen carriage 2, not shown in the drawing.
  • the printing cylinder 1 and the screening carriage 2 start up at a synchronized speed on the basis of corresponding control signals.
  • the two displacement measuring systems 8 and 12 transmit the respective movement positions of the printing cylinder 1 and the screening carriage 2 to the control units 15 and 16, respectively.
  • the movement positions are compared in the control units 15 and 16 with the control signals which determine the pressure path. If the movement positions correspond to the relevant control signals, a signal is sent from the respective control unit 15 or 16 to the Computing unit 13 transmits, which then outputs a control signal for stopping printing cylinder 1 or screen carriage 2 to control unit 15 or 16.
