Definitions

  • the invention relates to a machine for screen or screen printing, which has at least one functional component, a permeable or screen-like printing form, which is stenciled according to the desired printing image or pattern, a squeegee stroking over the printing form for pressing color through the printing form onto a printed matter, for example printing material or paper web, and an actuator for making contact between the printing form and the printing material and for removing the printing material from the printing form.
  • a screen printing machine is known (DE 37 30 409 A1), in which separate, mechanically decoupled, coordinated controllable drives are provided for the movement processes of the individual organs, in particular a holder and a screen holder, which are connected to a CNC control.
  • the individual drives are formed by electric motors in connection with toothed belt drives, the coupling between the drives and the functional components can be realized with a large number of mechanical parts such as gear wheels or toothed belts, connecting shafts, etc.
  • These construction parts result in a connection or coupling to the drive motor which is only slightly rigid, these disadvantages being caused in particular by play between the toothed belts and gearwheels in engagement and / or spring elasticities of the construction parts. This affects the accuracy of the motion control and sequences and thus the precision and quality of the printed image.
  • the object underlying the invention is to create a completely new type of control and synchronization for the necessary functional components of a screen or screen printing machine, avoiding the disadvantages and problems mentioned above, which is characterized by low mechanical wear, the possibility of structurally compact accommodation and Shielding, high adaptability to special requirements, substrates, ink viscosities, etc. and in particular characterized by a simplified and reliable construction and assembly structure.

  • one or more programmable logic controllers can be used.
  • the drive units can preferably be implemented electrically, expediently as position- or speed-controlled servomotors, the rotor of which is connected to the functional component to be moved or a part thereof in direct drive technology.
  • a linear motor is used as the electric motor for the functional components to be moved linearly.

  • the linear guide of which, for example, in the form of a rail and / or the machine chassis or in each case with a part thereof made in one piece.
  • This could be designed, for example, in such a way that the screen slide has a linear rotor equipped with permanent magnets, and that the machine chassis receiving it is interspersed with current coils as a stator, analogous to a linear synchronous motor.
  • the same is conceivable for flood and squeegees of a screen printing machine.
  • a hierarchical structure is advantageously formed between the functional components, the respectively assigned drive units and the control system in such a way that the control system forms the master function and the drive units with associated functional components each form the “slaves” to be instructed.
  • the control system can be provided with a memory module designed and programmed in such a way that printing and / or machine status parameters can be called up, stored and accessed via an interface designed for communication with an operator, an external computer and / or in a computer network is. Corresponding data can thus be transferred to a central computer via a network or can be adopted by the latter.
  • the screen printing system according to the invention can be easily expanded in a modular manner: in the presence of a transport mechanism for moving printed matter to the actuator and for removing it, a further drive unit can easily be coupled, which can then easily be subordinated to the control commands of the control system or connected to it.
  • the transport mechanism in which the transport mechanism is realized with an input-side and / or output-side roller, around which the printed matter can be wound, the transport mechanism drive unit is connected to either two rollers or only one, the other roller being connected to the drive unit indirectly, for example via a gear or toothed or belt drive, coupled or driven freely by the print material to be transported. Material from the roll (roll printing) can thus also be provided as the printing material.
  • the effort and cost is saved if, according to a special embodiment of the invention, at least one of the functional components is conventionally and / or exclusively mechanically coupled (indirectly) to the drive unit of another functional unit and / or is indirectly or mechanically synchronized with the other functional unit.
  • the abovementioned mechanical components such as gears or toothed or belt drives, can serve as a means.
  • the problem with the two-stroke method from the above-mentioned prior art is that both in the flooding and in the pressure cycle, the screen carriage reverses in each case past the flooding or printing doctor blade in principle at the same speed.
  • the invention offers the possibility of a special one Execution opens that the control system is designed or programmed (implementation of a specific control module for it) that the linear drive necessary for the screen slide to move past the doctor unit is accomplished by a drive unit that the control system for the forward movement at a different speed than for Return movement is controlled. This achieves the advantage of decoupling the flooding and printing speeds in a screen printing machine.
  • a functional component in particular the printing form for its movement, is assigned a plurality of drive units or linear drives, which act simultaneously or drive in parallel, in order to avoid twists and mechanical distortions, together with the associated loads on this functional component, which can impair the print quality.
  • a further advantage of the concept according to the invention namely assigning own drive units to the at least essential functional components and subordinating them to a higher-level control system, consists in improved possibilities for human-machine communication: the control panel known per se for screen printing machines for functions such as typing, automatic operation, emergency switches , Let the paper through without pressure, etc., can be connected directly to the control system via an appropriately designed interface, which then forwards corresponding control commands to the drive units, which may be arranged as slaves.

Rather, it can also be applied to the known roll-off screen printing (cylinder printing) with a fixed squeegee: the printing form, which is designed around the fixed squeegee with a hollow cylindrical cross-section, and the actuator designed as a printing cylinder are each connected to a separate drive unit, which is controlled by the control system. In this way, on the one hand, an exact synchronization of the rotations of the printing form and the printing cylinder can be taken into account.
  • different speeds can also be realized for the two functional components, so that, for example, changing thicknesses of the printed matter when it is wrapped around the printing form or the printing cylinder can be compensated for by appropriate variation of the respective drive speed by means of the control system.
  • the control system sets the printing form and the actuating element in a time-delayed manner relative to one another with respect to a point in time that is decisive for the start of printing.
  • the guide carriage of a screen printing machine can only be brought into linear motion when the registration of a sheet of paper on the printing cylinder as an actuator has been awaited.

  • the process can be set using the travelable angular path of a printing cylinder.
  • the advantage is the possibility of slippage or other asynchrony between the printing form and the printing cylinder.
  • the invention opens up the further, advantageous embodiment that the printing form and the actuator are mounted with a (preferably linear) variable distance from one another, at least one of these functional components being connected to a linear drive controlled by the control system.
