Definitions
- the invention relates to a method for correcting a register error. Such methods have been known for a long time. They are discussed inter alia in the still unpublished German application with the application number 102 54 836.
- Register errors have a number of sometimes very complex causes, including those made by the operator or the machine control changes in the operating parameters of the machine. These operating parameters include, among others, the printing speed or the temperature prevailing in the machine hall.
- operating parameters include, among others, the printing speed or the temperature prevailing in the machine hall.
- a machine operator checks register accuracy based on register marks and then makes corrections. More recently, registration accuracy has been increasingly pursued with the aid of cameras that control the substrate.
- the object of the present invention is to carry out a method for correcting a register error, which results in less printed substrate of limited quality or waste.
- the invention is based on a register method of the prior art in which also the register errors caused by the change of the operating parameters of the machine are minimized in a conventional manner.
- the control device transmits the change to the control module, - which determines based on the change of the register signals, which drive the actuator means for correcting the register error.
- the invention is equally applicable to the longitudinal as well as the transverse registers. Therefore, among the actuators in the longitudinal registers understood primarily the drive of the printing cylinder. When cross registers actuators are used, which change the position of the printing cylinder transversely to the printing material.
- a control device within the meaning of claim 1 is any type of control or operator terminal, with which or by which changes the operating parameters of the printing press can be made.
- Control module may be a separate hardware element, but also a software module integrated in a modern computerized control device.
- the invention takes advantage of the fact that changes in the operating parameters performed by the operator or a modern machine control are known before printed material of inferior quality is produced.
- Fig. 1 is a schematic diagram of two printing units
- Fig. 2 is an illustration of the control principle
- FIG. 3 is an illustration of the course of the speed of the printing material in an acceleration phase
- FIG. 4 is a representation of the acceleration profile of the printing material in an acceleration phase
- FIG. 5 is a representation of the course of the first derivative of FIG
- Fig. 1 shows a schematic diagram of two inking units F1 and F2 a gravure printing machine.
- the inking units each comprise the format cylinders D1 and D2 and the impression rollers P1 and P2.
- the printing material web which is identified by the reference numeral 1, runs between the two printing units on the guide roller 2.
- the course of the printing substrate 1 in the acceleration phase is shown with a continuous line, while the course is shown in dashed lines in a braking phase.
- the mass or the moment of inertia of the guide roller is crucial for the different trajectory during acceleration and braking, since in both cases, the adaptation of the peripheral speed of the guide roller to the web speed by transferring a force from the printing substrate to the guide roller and so on positive or negative acceleration is triggered. This circumstance leads inter alia to an elongation of the material web.
- the sequence of a register method according to the invention is outlined in FIG. 2 with reference to the inking unit F2.
- the drive M2 of the format cylinder D2 is made by a control module 5, which may be configured as a software module or as a hardware component.
- the control module adds to a conductance, which is fed via the control line 8, correction values - also as Register signals are called - up.
- the correction values arrive via the control line 7 from the calculation module 6 to the control module 5.
- the calculation module 6 determines from the first derivative of the acceleration after the time da / dt and the values K (machine constant), B width of the printing material, D (thickness of the printing material) and E (modulus of elasticity of the printing substrate) the correction values. Much of these values are already known to the machine control system and can be further processed analytically. However, in practice, empirical values stored in memory devices, which concern, for example, typical material behavior or the machine constant K, will also be used.
- control device 11 which includes, for example, input means 13 for a machine operator and other computer capacity.
- the changes in the operating parameters are initiated from here 11, 13 and transmitted via the communication means 9 to the computing module 6 or control module 5.
- Figure 2 is a functional or schematic diagram.
- an industrial computer can also combine the entire functions of the control device 11 and the modules 5 and 6, as indicated by the curly bracket 14.
- the control and computation modules are preferably program modules and the control lines 7, 8, 9, 10 are any means of communication within the computer.
- the type of torque transmission 12 of drive M2 to the form cylinder D2 is arbitrary.
- Figures 3 to 5 show the course of speed, acceleration and the first derivative of the acceleration, plotted against the time versus time, when the speed of the web is increased during a period, and then held back to the achieved higher level.
