Definitions

  • Electrographic printing or copying machine with a heat-setting station and an arrangement for program-controlled setting of operating parameters of the heat-setting station.
  • the invention relates to an electrographic printing or copying device with a heat-setting station and an arrangement for program-controlled setting of operating parameters of the fixing station.
  • heat-fixing devices are used in electrographic printing or copying machines which work according to the electrophotographic, ionographic or magnetographic principle, which have a preheating saddle with a downstream fixing zone comprising a heated fixing roller and a pressure roller.
  • Such heat fixing devices are e.g. known from US-A-4 147 922 or JP Abstract Vol. 13, No. 120, March 24, 1989 (JP-A-63-292177).
  • the print quality of such devices depends crucially on the fixing quality that can be achieved with the fixing station.
  • the fusing quality depends on the various operating parameters of the fusing station. These are e.g. the fixing energy supplied to the recording medium and the negative pressure with which the recording medium is braked and pressed against the preheating caliper.
  • the fixing energy supplied is of particular importance. It must not be too big and not too fast are fed to the record carrier, because otherwise the record carrier is stressed too much and permanent deformations interfere with the paper postprocessing. On the other hand, the fixing energy must be so high that the loose toner images are securely connected to the recording medium. It is therefore beneficial to regulate the fixing energy to be supplied.
  • the fixing quality depends crucially on the characteristics of the recording medium. These characteristics are in particular the paper basis weight and other data describing the structure and properties of the paper or other recording media, e.g. Variety labeling data.
  • the fusing quality depends particularly on the paper basis weight if a very large paper basis weight spectrum has to be processed, e.g. in a range from 60 gr / qm to 160 gr / qm. In general, the larger the paper basis weight, the worse the fixing quality becomes with otherwise the same paper parameters.
  • the paper In order to achieve a good connection of the toner image to the paper fiber structure, the paper must be heated to a temperature in the range of the melting temperature of the toner images, which is in a range of approximately 90 to 110 °, before it passes through the fixing gap of the fixing station.
  • the preheating of the paper is achieved when using paper webs by pulling the paper web over a heated preheating saddle. The so reaching paper temperature at the outlet of the saddle is thus dependent on the temperature of the heated saddle and the time during which the paper is exposed to the saddle temperature.
  • the melting temperature can essentially only be achieved by increasing the saddle temperature with otherwise the same geometrical dimensions of the saddle.
  • the toner image on the preheated paper web is firmly connected to the paper surface structure of the paper web under pressure and heat.
  • the heat flows from the hotter fixing roller at a temperature of about 180 to 220 ° to the toner image, which melts in the border area to the paper surface and from there to the preheated paper web. Preheating the paper web is necessary because otherwise too much heat would be removed from the fixing gap by the paper web.
  • the paper has a larger paper basis weight and thus a larger mass, more heat must flow in order to achieve a constant contact temperature between the toner image and the paper. This in turn requires an increase in the fuser roll temperature.
  • the preheating saddle e.g. can consist of a preheating saddle and an actual heating saddle and adjust the fixing roller depending on the paper basis weight.
  • Continuous paper printers in particular must be able to process an extremely wide range of papers with a wide variety of paper properties, e.g. with a paper basis weight of 50 gr / sqm to 160 gr / sqm, coated and uncoated papers, recycled papers, plastic-coated papers, long-fiber and short-fiber papers, etc.
  • paper types with new properties come onto the market every year that are processed by the printers without hardware changes Need to become.
  • the paper In the case of data printers which work at very high printing speeds, in order to achieve an acceptable fixing quality, the paper must be preheated before the fixing gap is reached.
  • the paper web is usually preheated via the back of the paper web by running it over a heated, temperature-controlled preheating saddle with good thermal contact. Then the actual one takes place Fixing the toner images on the paper web in the fixing nip by means of pressure and heat, the heat starting from the fixing roller being fed directly to the toner image.
  • the aim of the invention is therefore to provide an electrographic printing or copying device with a heat-setting station and an arrangement for program-controlled setting of operating parameters of the fixing station, which enables the user to easily set the operating parameters.
  • Another object of the invention is to design the setting so that the fixing qualities do not deteriorate as a result of the setting process.
  • a constant fixing quality is guaranteed by a program-controlled setting of the operating parameters depending on the characteristics of the recording medium.
  • This setting is simplified for the user in that he can enter the characteristic data and select fixing levels via a control panel.
  • the coupling of the setting parameters of the fixing station enables easy selection and setting without the fixing quality deteriorating by entering an unfavorable setting parameter combination.
  • the input of recording medium-specific characteristic data and the selection of the corresponding fixing levels is made considerably easier by a menu control.
  • the operator is presented on the control panel with a menu of the various adjustable fixing levels and the paper data to be entered, in particular the weight per unit area.
  • An electrophotographic printing device for printing on continuous paper contains a heat fixing device shown schematically in FIG. 1.
  • the heat fixing device is designed as a thermal pressure fixing device. It contains a heating roller 11 heated by radiators 10 and a pressure roller 12 which can be pivoted and pivoted by an electric motor to the heating roller 11.
  • the heating roller consists of an aluminum cylinder with a heat-resistant coating arranged thereon, the pressure roller likewise consists of an aluminum cylinder with a silicone coating.
  • the heating roller 11 is driven by an electric motor.
  • the heating roller 11 is assigned an oiling device 13 for applying separating oil to the heating roller.
  • a heated preheating saddle 15 with associated vacuum brake 16 is arranged upstream of the rollers in the direction of recording medium transport, which serves to preheat a recording medium 17 designed as continuous paper and to supply it to the actual fixing gap between the rollers 11 and 12 in the preheated state. Braked by the vacuum brake 16 and driven by the rollers, the recording medium 17 is guided tightly over the preheating caliper 15. A loose toner image on the recording medium is preheated on the preheating saddle 15 and fixed between the rollers 11 and 12 by heat and pressure.
  • a cooling device 18 arranged downstream of the rollers 11 and 12 in the paper running direction ensures cooling of the heated paper.
  • the cooling device 18 contains a cooling surface 19 provided with openings, which is swept by the recording medium 17, with cold air supplied via an air supply channel 20 flowing out of the openings and a cooling air cushion being created under the recording medium 17.
  • air is blown onto the concrete side of the recording medium via an opposite profile.
  • the continuous paper 17 is preheated via a preheating saddle 15 which consists of two heated saddles connected in series, namely a stationary preheating saddle 21 and a heating saddle 23 which can be pivoted about a pivot point 22.
  • the preheating saddle 21 and heating saddle 23 form two separate heating zones when viewed in the direction of paper travel .
  • the entire preheating section has a length of approximately 500 to 700 mm.
  • the paper 17 slides during preheating with its toner-free side on sliding surfaces 24 of the preheating saddle 21 or heating saddle 23.
  • the sliding surfaces or the saddles are curved with a radius of curvature which in the example shown is 700 mm. Due to the curvature of the sliding surfaces in connection with the train through the rollers 11 and 12 and the braking by the vacuum brake 16, a force component acts over the entire length of the saddle, which presses the paper 17 against the sliding surfaces 24, and the stability of the paper flow on the saddle becomes in addition thereby promoted.
  • the saddles 21 and 23 have elongated depressions 25 which extend transversely to the paper running direction and extend over the entire width of the saddles. They are connected to a vacuum channel 27 (FIG. 1) by lateral bores 26.
  • the vacuum channel runs below the saddles and is equipped with a vacuum generating device, e.g. a pump. Due to the negative pressure, the recording medium (paper) is sucked onto the sliding surfaces 24 of the saddles and the water vapor released by the preheating is sucked out.
  • a vacuum generating device e.g. a pump. Due to the negative pressure, the recording medium (paper) is sucked onto the sliding surfaces 24 of the saddles and the water vapor released by the preheating is sucked out.
  • the saddles 21 and 23 are heated by electrical resistance elements in the form of interchangeably arranged ones Heating cartridges 28.
  • the saddles 21 and 23 have through bores 29. These holes enable the replacement of each individual heating cartridge 28 in the event of a defect.
  • the saddles 21 and 23 can thus be produced inexpensively from an extruded aluminum profile.
  • each saddle 21 or 23 is divided into three heating zones 30/1, 30/2 and 30/3 transversely to the direction of paper travel (FIG. 2).
  • These transverse heating zones 30/1 to 30/3 are used to adapt the saddles to different recording medium widths.
  • the first heating zone 30/1 is delimited on one side by the fixed paper running edge 31.
  • This heating zone 30/1 is as wide as the minimum width of the recording medium.
  • the remaining area of the saddles up to the maximum recording medium width is divided into the equally wide heating zones 30/2 and 30/3.
  • Each of the transverse heating zones 30/1 to 30/3 has a temperature sensor 32/1 to 32/3 for regulating the heating zones. It is located approximately in the middle of the respective heating zones across the paper running direction.
  • the sensor position When viewed in the paper travel direction, the sensor position is selected so that the same temperature can be controlled both in the standby state of the printing device (standby) and in the printing mode itself. This simplifies the temperature control.
  • the control temperature and the position of the sensors 32/1 to 32/3 are selected so that the paper temperature at the end of the saddle is just as high during the starting phase as during a longer printing phase.
  • the area from the middle to the last third of the saddles has proven to be a favorable sensor position.
  • the heating zones 30/1 to 30/3 are generated by the arrangement of the heating cartridges 28 in the bores 29.
  • a cartridge for the two outer heating zones 30/1 and 30/3 is inserted into the first hole of a saddle in the direction of paper travel.
  • a heating cartridge 29 for the middle zone 30/2 is inserted into the second hole.
  • the third hole is equipped like the first, etc. There are therefore six heating cartridges 28 in each heating zone 30/1 to 30/3.
  • the surface temperature of the saddles and thus the temperature of the recording medium are controlled with the aid of a control arrangement as shown in FIG. 3.
  • the control arrangement contains an actuator 33, for example in the form of individual relays for coupling the heating cartridges 28 to a power supply unit 34.
  • the control element 35 is connected downstream of the control element 35 with the heating cartridges 28.
  • the actual temperature is detected by the temperature sensors 32/1 to 32/3 and converted into an electrical control signal by the sensors and amplified in a subsequent amplifier 37.
  • a microprocessor-controlled control device 39 coupled to the amplifier 37 compares the actual temperature with a predefinable target temperature TS and regulates the target temperature as a function of the control deviation.
  • the control device contains an analog-digital converter 40 with an associated program-controlled two-point controller 41.
  • the microprocessor-controlled control arrangement 39 is also coupled to the controller 42 of the printing device, which has an arrangement described below for program-controlled setting of operating parameters of the fuser station.
  • the control arrangement shown in FIG. 3 can be part of the program-controlled setting arrangement for the operating parameters of the fixing station. It is used specifically to regulate the Temperature at the preheating saddle. It is regulated to a target temperature TS, which is referred to below as a control target value.
  • the setpoint temperature at the preheating saddle is the temperature at which the paper leaves the preheating saddle or the entry temperature of the paper into the fixing nip between fixing roller 11 and pressure roller 12.
  • An additional low-voltage power supply unit 44 which is coupled to the actual power supply unit 34, provides the power supply the device control and thus the microprocessor-controlled control device 39.
  • the microprocessor-controlled control arrangement 39 switches the heating cartridges on to the phases of the three-phase network of the power supply unit 34 via the actuator 33. After reaching the target temperature, they are separated from the mains again via the actuator 33. After starting the printing operation, depending on the paper temperature, the paper basis weight, the printing speed and the surface quality of the paper and the width of the paper, heat is removed from the preheating saddle 15 via the paper.
  • This influence of disturbance is symbolically represented in the control circuit of FIG. 3 as disturbance SG.
  • the actual temperature resulting depending on the deduction of the disturbance variable is detected by the temperature sensors 32/1 to 32/3 and supplied to the microprocessor-controlled control arrangement 39 in the form of electrical signals. This activates the actuator 33 in a corresponding manner until the predetermined target temperature is reached again.

  • the operating parameters of the fusing station are the fusing energy which is fed to the recording medium during the fusing process via the preheating caliper 15 and the fusing roller 11, and the negative pressure in the area of the paper brake 16 and the preheating caliper 15.
  • This negative pressure in the paper brake 16 and in the negative pressure duct 27 can be adjusted via a vacuum generating device in the form of a blower with associated control valve. The negative pressure is detected by means of corresponding commercially available negative pressure sensors.
  • the arrangements shown schematically in FIGS. 4, 6 and 7 are used for program-controlled setting of the operating parameters of the fixing station. These are, for example the fixing energy transmitted on the recording medium and the negative pressure in the paper brake 16 and on the preheating caliper 15, but also operating parameters such as printing speed, printing operation in general, standby mode etc.

Further setting parameters are, for example, the electrical control values for determining the negative pressure via the negative pressure generating device.
  • control setpoints are assigned control setpoints as a function of characteristic data specific to the recording medium, such as paper basis weight, paper type or other data characterizing the structure of the recording medium.
  • control setpoints are, for example, calculated setpoints for temperature and vacuum, via which a control arrangement (for example FIG. 6 in the case of temperature control of the preheating saddle 15) then regulates the operating parameters “fixing energy” and “vacuum”.
  • the characteristic data specific to the recording medium must be recorded and supplied to the arrangement in the form of electrical signals, and on the other hand a separate selection of the fixing stages itself is provided.
  • the fixing energy to be supplied to the recording medium depends on the one hand on the characteristic data specific to the recording medium, in particular the paper basis weight, which can be automatically recorded or entered.
  • the amount of heat input i.e. the fixing energy to the front and back of the paper web can be easily selected for the user without the fixing quality suffering because paper properties which determine the curvature of the paper web under the influence of temperature cannot be detected by sensors.
