Definitions

  • the invention relates to a device and a method for adjusting a plurality of actuators for the ink layer and / or dampening layer thickness profile and / or for register adjustment in a printing press with a control panel made up of several or a plurality of display elements, each element of which represents a manipulated variable of an actuator represents and serves as feedback for a corresponding actual value.
  • DE-AS 27 27 426 It is known from DE-AS 27 27 426 to display the actual values of the positions of the actuators, which are actuating cylinders, on a display panel by means of LEDs.
  • the actuators for the individual actuators can be switched on by the printer using pushbuttons, so that the printer can specifically change the position of the actuators.
  • An arrangement has also already been proposed in which set values for the position of the actuators can be entered in the setting device and then the actuators are automatically adjusted until they reach the set position.
  • the target values can be entered manually, for example using the setting buttons.
  • target values are entered in order, for example, to preset the actuators of the printing press at the start of a print job, the information about the individual target values being able to come, for example, from an earlier same print job; however, the target values can also be entered by the printer during printing in order to counteract color deviations in the printed product, which could occur, for example, as a result of temperature changes in the environment.
  • EP-A-0 018 551 describes a device for inputting setpoints in the control of an injection molding machine using an electronic data display device.
  • parameters are entered using a first sensor and the associated function is entered in a buffer of the data display device using a second sensor and represented in a cathode ray display tube by a time-controlled, running electron beam as abscissa and ordinate values.
  • a setpoint curve is then written on the display screen by means of a light pen, according to which the injection molding machine is to move, the associated pairs of values of the setpoint curve being transferred to the machine control on command.
  • the disadvantage here is that the value pairs can be used on the basis of the specified parameters and the function for controlling a maximum of two servomotors. Due to the inevitable use of three separate input means, this type of value entry is also cumbersome and very time-consuming. In addition, the rough recording of curves on a screen precludes the entry of concrete manipulated values, for example in the tenths or hundredths of a millimeter range.
  • the invention has for its object to provide a device and a method of the type described, in which the printer in a simple manner concrete signal values or their changes for control for one or a group of actuators using the existing control panel as quickly as possible in the press can enter and display.
  • this object is achieved in that a light stylus that is optically operatively connected to the control panel is provided as a light transmitter or light receiver for inputting the setpoint value, the location and value of the setpoint value for at least one actuator is provided by its optical contact point in the control panel and
  • the light receivers or light transmitters assigned to the display elements or forming the display elements themselves are defined, these light receivers or light transmitters being controllable in a time cycle to determine their location and thus value, and the display elements not only serve for feedback of the actual value, but also as a setpoint display.
  • the light pen can have a light source which interacts with light-sensitive elements arranged in the display panel.
  • the light pen has a receiver which interacts with light-emitting elements arranged in the display panel.
  • These light-emitting elements can be used for display at the same time and can, for example, also be the screen of a television picture tube or another cathode ray tube.
  • a light stylus is provided that is optically operatively connected to the control panel and is both a light transmitter and a light receiver and for determining the location and value of the signal transmitted by means of the light stylus with light-absorbing or light-reflecting and controllable in one time cycle Elements of the control panel interacts.
  • the element corresponding to the light pen is a display element that does not emit light energy and therefore arrives with low power consumption, e.g. a liquid crystal element (LCD).
  • LCD liquid crystal element
  • the object is also achieved in an independent manner in that a light stylus that is optically operatively connected to the control panel is used for inputting the setpoint is provided, which forms at its optical contact point with the control panel the said operative connection between corresponding elements provided in this control panel, designed as a light transmitter and light receiver, and in this way determines the location and value of the signal to be transmitted by the light stylus.
  • a light stylus that is optically operatively connected to the control panel is used for inputting the setpoint is provided, which forms at its optical contact point with the control panel the said operative connection between corresponding elements provided in this control panel, designed as a light transmitter and light receiver, and in this way determines the location and value of the signal to be transmitted by the light stylus.
  • light-emitting diodes can then be provided in the display field for the displays to be displayed by the display field.
  • the light-sensitive elements arranged spatially in the display field must be sufficiently decoupled from the light-emitting diodes.
  • the solution to the problem is that setpoints and commands or their changes are entered into the printing press by means of a light pen, for which purpose the light pen can be placed selectively on the control panel or moved in the direction of the sequence of the actuators, the movement of the light pen in this Direction of the control panel is straight, stepped or curved, and the setpoint or command is transmitted by means of optical and / or optoelectronic elements corresponding to the light pen in the control panel and the setpoints and or commands or their changes in addition to the adjustment of one or one Number of actuators assigned from the left, right or on both sides of the input point in the control panel can be used to the value entered in each case.
  • control panel simultaneously serves to display the actual values and target values of the actuators.
  • the part of the control panel used for this display is referred to below as the display panel. It is possible that the entire control panel is the display panel at the same time.
  • the advantage of the invention according to the four proposed solutions is the simple and quick entry of data and / or control commands. For example, if the printer needs to enter new or changed setpoints for individual actuators or for all actuators, he only has to move the light pen over the display field, but does not have to operate a rotary knob or a button or the like for each of the actuators.
  • the movement of the light pen over the display field is preferably a continuous curve, generally in the form of a more or less wavy curve, which is very easy for the printer to carry out.
  • a punctual input of values, in which the printer places the light pen on certain points of the display field, then removes it from the display field and then places it on a new point, is also possible, but not absolutely necessary.
  • the setting process can also be carried out by placing the light pen at certain points on the display panel.
  • the maximum speed at which the printer can move the light pen over the display field reference is made to the later explanations.
  • the invention is mainly explained in connection with the input of target values for the adjustment of the actuators for the ink layer thickness profile, the invention also includes the input of other data, for example for the adjustment of the registers of a printing press, whereby the register-accurate printing of different colors can be adjusted , as well as the input of control commands using the light pen, although in the exemplary embodiment described later the control commands are input using pushbuttons.
  • the elements designed as light receivers and / or light transmitters are arranged in the form of a matrix, in which each actuator is assigned a row (zones ZI to Z32) of elements and in which the rows are transverse to their own Are arranged side by side in the longitudinal direction.
  • each row of diodes which in the exemplary embodiment is arranged as a vertical column, is assigned to a specific actuator and contains a predetermined number of diodes, for example sixteen.
  • the printer must enter the light pen to enter the desired position of the row of diodes assigned to the relevant actuator (or more generally to the corresponding position on the display panel) in order to enter each individual setpoint.
  • the printer can guide the light pen from left to right or right to left over the entire display field, cover only part of the length of the display field, or only place the light pen on one or a few desired locations.
  • a different operating mode (step profile) of the light pen can be advantageous, which can be switched according to an embodiment of the invention, and in the case of the only desired value entered at any point on the control panel (display field) for one of the actuators as the desired value For a predetermined group of actuators that follows at this point is used.
  • the predetermined group of actuators can include all those actuators that are shown in the matrix (or the display field) on a predetermined page, e.g. to the right, from that row of elements in which a target value was entered by the light pen.
  • the printer must therefore e.g. If he wants to enter the same target value for all actuators, enter this target value only at the leftmost position on the display panel, because this target value is automatically adopted for all actuators further to the right in the display panel.
  • the printer can also move the light pen from left to right across the display panel and, as a result, then enter the same target values as if it had switched on the above-mentioned operating mode.
  • step profile the first-mentioned operating mode
  • the predetermined group of actuators which is set to the same target value as that which was directly controlled by the printer by means of the light pen, can also be selected differently in such a way that the step profile of the light pen can be switched such that for the predetermined one Group of actuators at least one of the following options can be switched on:
  • the predetermined group of actuators is located on the right, left and / or on both sides of that row of elements in which a desired value was entered by the light pen.
  • two or three actuators located to the right and left of the directly actuated actuator can belong to this group, or all to the left of the actuated actuator, or all.
  • a cathode ray tube or a television screen is provided as the display field
  • the interaction with a light-sensitive light pen can follow in the manner known from computers in that the screen is written line by line by the cathode ray, at those points where there is a separate pictorial representation should not take place, the cathode ray only causes a very low screen brightness, which is sufficient, however, to have the light receiver respond in the light pen.
  • the desired information is then entered from the point in time at which the light pen is attached and into the corresponding location in a memory.
  • Information to be displayed on the screen can be generated by a larger current of the electron beam, as is known and customary in television technology.
  • the elements designed as light transmitters are acted upon by current pulses in a predetermined sequence, such that that those elements which do not produce a display are subjected to such a short current pulse that they appear to the human eye to be non-luminous or only weakly luminous, whereas those elements which represent a display are subjected to a relatively long current pulse which it appears to the human eye to shine brighter, and that these elements are subjected to a short pulse in addition to the long pulse mentioned, and that the light pen is only activated during the times of the short pulses.
  • the advantage here is in particular that a purely digital control of the diodes is possible, since the brightness control is carried out only via a time control of the current flowing through the diodes, whereas the current intensity can be the same for all diodes.
  • Those diodes which cause a display are thus operated in time-division multiplex, and are not suitable for actuating the light pen during those times in which they display the display, since the light pen is not activated.
  • This embodiment can be implemented particularly easily because, for example, the sixteen diodes of a column which are assigned to a specific actuator can be acted upon in succession with a short pulse each time, the temporal position of these pulses being fixed and thus identification of the respectively illuminated diode by permits the light pen, and after this period, in which each of the 16 diodes, for example, has been briefly energized once, a longer period is provided in which any one of the diodes is energized to represent a display visible to the printer; which of the diodes lights up during this period depends, for example, only on the respective actual position of the actuator assigned to the column.
  • the display panel is also used to display other information can be, for example, to display the target values entered by the light pen, or simply to acknowledge that the light pen has entered information in the relevant column of the display panel.
  • these further displays could be characterized by a lighting duration that deviates from the display of the actual value, for example by a flickering lighting up.
  • the speed of movement is with which the printer is allowed to move the light pen over the display field.
  • this maximum travel speed of the light pen in the rough display operating mode is 60 cm / s.
  • the permissible speed of movement of the light pen can be increased in a further development of the invention.
  • two control cycles are provided for the elements, with all elements being controlled in a predetermined sequence with a predetermined pulse sequence speed with short pulses for the light pen operation in a first control cycle, and the arrangement being such that after the light pen has entered a target value
  • a second control cycle is used, which, with the same pulse repetition speed, controls only a part of the elements at that position on the display panel at which the light pen for entering the target value was placed.
  • the printer is placing the light pen anywhere on the display panel.
  • FIG. 1 shows a side view, partially broken off, of an offset printing press 1 with five printing units, two of which are not visible. Some parts of a printing unit 9 are shown in one of the machine parts.
  • the printing unit has a plate cylinder 2, which carries the printing plate and interacts with the blanket cylinder 3, which transfers the printing ink to the paper to be printed, which runs between the blanket cylinder 1 and an impression cylinder 4. From the associated inking unit, only the ink metering box 5 with duct 6 is visible.
  • the printing unit 8 is also assigned a dampening unit 11 which has a water tank 12. Numerous other devices, in particular rollers for transporting the printing ink and water, and transport rollers are not shown for the sake of simplicity.
  • the servomotor 9 designed as a DC motor drives a shaft 15 to which a potentiometer 17 is coupled.
  • the shaft 16 carries a section 18 which is threaded at its end and on which an adjusting piece 19 is stirred so as to be screwed, which is prevented by a link 20 with a lever 21 rigidly connected to the actuating cylinder.
  • the lower bottom of the ink metering box 5 is formed by a plastic film 22, and depending on the position of the adjusting cylinder 15 having an eccentric twist 14, this plastic film 22 pressed more or less close to the outer surface of the duct 6, thereby forming a more or less thick gap 23 through which the ink can reach the lower region of the duct roller 6.
  • the ink is then removed from other rollers of the inking unit in a manner not shown.
  • the adjusting cylinder 15 is thus adjusted by displacing the adjusting piece 19 as a result of a rotary movement of the servomotor 9.
  • Two of the electrical connections of the potentiometer 17 are connected to a voltage source, and the wiper of the potentiometer is led out via a third line 24.

  • the rough display type of display exactly one diode lights up brightly from each column of the light-emitting diodes 35, so that 16 different positions of the respectively assigned actuating cylinders 15 can be read on the display panel 31 in this way.

  • the display field 31 always shows the data contained in the display device 45. If the printer does not intend to use the light pen, the device is in a state in which the actual values of the actuators are contained in the display memory 45 and are thus displayed. If the printer switches the device to light pen operation by entering a corresponding control command (in the exemplary embodiment via a pushbutton), the actual values just mentioned are still displayed initially. However, as soon as the printer has entered a target value for a zone using the light pen, this target value is immediately displayed in this zone, but no longer the actual value.

  • each of the sixteen light-emitting diodes is acted upon by a short current pulse for a period of 50 ⁇ s, then the light-emitting diode that should be clearly visible to the human eye for rough display is actuated for 50 ⁇ s; then then in the same way to control the LEDs of zones 2, etc. to 32, which is then followed by the control of zone 1.
  • the light pen is not active during those times in which the diode causing the coarse display is activated during the illustrated time of 50 microseconds.
  • FIG. 7 shows a representation of a time diagram similar to that of FIG. 6, but here for the operating mode light pen operation with fine display of the actual values, wherein, as mentioned above, the fine display also shows a rough display.
  • zone 1 brief control of all the light-emitting diodes in this zone is provided, as in FIG. 6, for the first 50 microseconds, then the light-emitting diode causing the fine display is activated for 50 ⁇ s, and finally the coarse display is brought about LED for 100 Ils supplied with current; Because of the longer lighting time, the latter LED appears brighter to the human eye.
  • the 50 ⁇ s of the next zone follow in which the individual light-emitting diodes are briefly energized once in order to enable light pen operation.

  • the throughput time or period from the activation of the first light emitting diode to the activation of the last light emitting diode is 32 ⁇ 100 ⁇ s, that is to say a total of 3.2 ms.
  • This speed of movement should generally be sufficient. If, on the other hand, the operating mode light pen operation with fine display according to FIG. 7 is used, the permissible maximum light pen traversing speed drops to 0.3 m / s because of the double throughput time or period time of 6.4 ms. This speed should also be sufficient in most cases, since in general the printer cannot enter the setpoints in this operating mode by drawing a possibly only slightly curved line on the display, but because he generally enters values that differ more visually from each other in the individual zones must, for example, control the bottom LED in some zones and the top LED in others.
  • the individual pulses characteristic of the light pen time of which 16 pulses within a period of 50 ⁇ s follow each other, fed. If it is assumed that the light pen was placed on zone 22 in the display field, the arrangement is accordingly made such that the individual pulses shown in FIG. 6 in zone 1 are not supplied to zone 1, but to zone 20, that subsequently the Zone 1 the pulse of 50 microseconds length is supplied to control the coarse display diode, then those shown in zone 2 in Fig. 6 Individual pulses are supplied to the diodes of zone 21 and so on, and the individual pulses that would be assigned to zone 5 (not shown there) in FIG. 6 are assigned to zone 25. The individual pulses assigned to the zone (not shown) in FIG. 6 would then again be assigned to zone 20 and so on.
  • zones 20 to 25 are activated with individual pulses to which the light pen can respond, much more frequently than in the operating mode according to FIG. 6.
  • the printer can therefore move the light pen in this area of zones 20 to 25 much faster than the above-mentioned speed of 0.6 m / s.
  • this maximum permissible travel speed is approximately 4 m / s.
  • the electronics does not observe a setpoint input for a predetermined time because, for example, the printer moves the light pen too slowly across the display field and thus does not cross the light-emitting diode columns arranged at a mutual distance of 32 mm from one another in sufficiently short time intervals, or because it does has removed the light pen from the display panel, the electronics switch back to the operating mode shown in Fig. 6, because in such a case there is a possibility that the printer leads the light pen through the air to another point on the display panel, which of the rapid sampling just described is not detected. In such a guiding of the light pen by the air of the Lich t stylus can no light pulses of the light-emitting diodes receive.
  • the period of time after which the electronics switch back to the operating mode shown in FIG. 6 when the input of a setpoint is not recognized can be, for example, 0.1 to 0.2 s.
