Definitions

  • the invention relates to a heat fixing device for fixing toner images on the front side of a tape-shaped recording medium in an electrographic printing or copying device, in which the rear side of the recording medium can already have a fixed toner image.
  • heat-fixing devices are used in printing or copying devices, which have a preheating saddle with a downstream fixing zone comprising a heated fixing roller and a pressure roller.
  • the already fixed print image which runs over the hot preheating saddle surface, is heated so strongly that it assumes a pasty to liquid state and is partially smeared on the saddle surface.
  • the more toner that accumulates on the saddle surface the more toner is transferred from the toner image to the saddle surface until there is a visible destruction of the toner image on the paper.
  • the paper web with the already fixed print image lies on the hot saddle.
  • the print image in the area of the preheating saddle surface is heated so strongly that it assumes a pasty to liquid state and sticks to the hot preheating saddle surface.
  • the toner image is torn from the paper web surface and sticks to the hot saddle surface.
  • the aim of the invention is therefore to provide a heat fixing device with a preheating saddle for fixing toner images on the front side of a recording medium in an electrographic printing or copying device, in which the rear side of the recording medium may already have a fixed toner image.
  • the heat fixing device can be used in printing or copying machines that work in both simplex and duplex mode.
  • PTFE or PFA compounds Materials that are made from fluorine compounds, such as PTFE or PFA compounds, have proven to be favorable.
  • the material can be evaporated, sprayed or glued onto a corresponding receiving surface of a preheating saddle.
  • PTFE or PFA compounds show a very good repellency against the toner material and very good properties against abrasion from the paper web.
  • components such as graphite or glass fibers that reduce wear can be mixed to a greater or lesser extent with the PTFE or PFA.
  • preheating saddles of this type are generally used in high-performance electrographic printing devices (between 2 million and 10 million A4 pages per month), wear-free operation over many years is impossible. For this reason, it is useful if the saddle surface can be replaced easily and easily if necessary, without the expensive basic structure of the heating saddle with heating elements having to be replaced.
  • a toner-repellent layer can be evaporated, sprayed or glued onto thin metal plates, in which case these coated individual plates are then exchangeably attached to the basic structure of the preheating saddle.
  • the toner-repellent layer is designed as a film which has a thin, thermally conductive adhesive layer on one side.
  • the adhesive layer is designed so that when the saddle is hot, the film can be easily removed again. A quick renewal of the saddle surface is therefore possible very quickly on site at the customer's site.
  • the toner-repellent layer can also be designed as a thin film, which is drawn off from a supply reel and guided over the preheating saddle surface and then wound up again. The film is moved very slowly in relation to the paper running direction.
  • the repellency of the surface against the toner image may be reduced.
  • it is advantageous to lift the recording medium off the saddle surface This can be done by creating an air cushion between the paper web and the saddle surface or sliding surface in the waiting state of the printing device with the aid of a blower device.
  • Another possibility for lifting is to provide a suitable lifting element, for example a tensioning wire, which engages behind the recording medium over its entire width. The preheating saddle and the lifting element are moved relative to one another in such a way that in a lifting state the recording medium is guided over the lifting element at a distance from the preheating saddle.
  • the paper web is automatically inserted into the printer.
  • the paper web must be guided over the preheating saddle, among other things. Coatings made of fluorine compounds become electrostatically charged on their surface when paper slides on them. Due to the electrostatic forces, the paper web adheres to the preheating saddle so strongly that it can possibly no longer be transported.
  • An advantageous admixture of electrostatically conductive substances such as graphite or the like can prevent the formation of electrostatic charges.
  • the adhesive is also conductive, in order to establish a conductive connection between the toner-repellent material and the grounded carrier.
  • An electrographic printing device for printing on continuous paper contains a heat fixing device, shown schematically in FIG. 1, as described in US Pat. No. 4,147,922.
  • the heat fixing device is designed as a thermal pressure fixing device. It contains a heating roller 11, which is heated by radiators 10, and a pressure roller 12, which can be pivoted and pivoted onto the heating roller 11 by an electric motor.
  • the heating roller consists of an aluminum cylinder with a heat-resistant coating arranged on it, the pressure roller also consists of an aluminum cylinder with a coating of silicone.
  • 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 caliper 15 with associated vacuum brake 16 is arranged upstream of the rollers in the recording medium transport direction.
  • 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 entire paper.
  • the cooling device 18 contains a cooling surface 19 provided with openings, which is swept by the recording medium 17, cold air supplied via an air supply channel 20 flowing out of the openings and producing a cooling air cushion 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 low-temperature 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, seen in the paper running direction two separate heating zones.
  • the entire preheating section has a length of approximately 500 to 700 mm.
  • the paper 17 slides on sliding surfaces 24 of the preheating saddle 21 or heating saddle 22.
  • the sliding surfaces or the saddles are curved with a curvature radius 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 paper 17 against the sliding surfaces 24. It also promotes the stability of the paper run on the saddle.
  • the saddles 21 and 23 have transversely to the paper running direction elongated recesses 25 which extend over the entire width of the saddles. They are connected to a channel 27 by side bores 26.
  • the air duct runs underneath the saddles and is connected to a pneumatic device that generates positive and negative pressure, for example a blower and a pump.
  • a pneumatic device that generates positive and negative pressure
  • the recording medium paper
  • the recording medium is sucked into the sliding surfaces 24 of the saddles by negative pressure and the water vapor released by the preheating is sucked out.
  • an air cushion is generated between recording medium 17 and saddle or sliding surface 24 by overpressure.
  • the saddles 21 and 23 are heated by electrical resistance elements in the form of exchangeably arranged heating cartridges which are arranged in bores 29.
  • the preheating saddle is designed as a low-temperature saddle, the heating power of which is regulated by a microprocessor-controlled control arrangement.
  • the heat fixing device is also suitable for fixing recording media which already have a fixed toner image on their back.
  • This toner image can be printed and fixed in a first pass on the back or the front of the recording medium, after which a further pass is applied and fixed on the corresponding other side in a further pass.
  • the sliding surface 24 consists of a toner-repellent plastic layer, of a fluorine compound, for example a PTFE or PFA compound, which is evaporated, sprayed or glued onto the machined surface of the preheating saddle 15.
  • PTFE Polytetrafluoroethylene
  • PTFE or PFA compounds show a very good repellency against the toner material and very good properties against abrasion from the paper web.
  • components such as graphite or glass fiber can be mixed to a greater or lesser extent with the toner-repellent layer.
  • heating saddles are generally used in high-performance electrographic printing systems with a page yield of 2 to 10 million A4 pages per month, these heating saddles are subject to relatively high wear. For this reason, it is favorable if the saddle surface can easily be replaced if necessary without the expensive basic structure of the heating saddle having to be renewed with heating elements.
  • the toner-repellent layer 30 is evaporated, sprayed or glued onto thin metal plates 31 in an exemplary embodiment according to FIG.
  • the thin metal plates 31 can have a thickness of 1 to 5 mm and they are interchangeably clamped or screwed onto the basic structure 32 of the preheating saddle.
  • the toner-repellent layer 30 can also be designed as a thin film, which has a thin, good heat-conducting adhesive layer on one side.
  • the adhesive layer is designed so that when the saddle is hot, the film can be easily removed again. A quick renewal of the saddle surface is therefore possible very quickly on site at the customer's site.
  • the toner-repellent layer 30 is designed as a thin film 33.
  • the film 33 extends over the entire width of the preheating saddle. It is wound up as a supply on a spool 34, which is attached in the saddle inlet area below the preheating saddle. Starting from this supply reel 34, this film is stretched over the preheating saddle in the paper running direction to the heating saddle outlet and wound up again on a take-up reel 35 below the preheating saddle. The film is moved extremely slowly in relation to the recording medium speed with the aid of a drive device coupled to the take-up reel 35 and wound onto the take-up reel 35.
  • On the inlet side supply spool 34 there is a film supply which can be designed for the entire printer service life. In this way, the preheating saddle is designed to be maintenance-free.
  • the repellency of the surface against toner can possibly be reduced.
  • air is supplied in the waiting state in an exemplary embodiment according to FIG. 7 via the pneumatic channel 27, the bores 26 and the slots 25, so that between the sliding surface 24 and the recording medium 17 an air cushion is created which keeps the record carrier 17 at a distance from the sliding surface 24. This prevents the recording medium from sticking to the preheating saddle surface.
  • a film 33 is used as the toner-repellent layer, an air cushion can be produced in a similar manner between the film 33 and the preheating saddle.
  • FIG. 1 A further possibility for lifting the recording medium from the preheating saddle in the waiting mode of the printing device is shown in FIG.
  • a lifting element engaging behind the recording medium 17 in the region of the preheating saddle for example in the form of a tensioning wire 38, is arranged in a fixed manner in holders of the printing device in such a way that the tensioning wire 38 comes to rest in a recess 39 in the preheating saddle in a position D of the preheating saddle assigned to the printing operation.
  • the tensioning wire 38 remains stationary and the paper web 17 is thereby lifted off the hot preheating saddle surface.
  • Another possibility is to pivot the tensioning wire 38 or other paper depositing elements out of the surface of the preheating saddle and to sink it back into the surface when printing starts.
  • the recording medium 17 is automatically inserted into the printing device.
  • the paper web must be guided over the preheating saddle, among other things.
  • Coatings made of fluorine compounds such as PTFE or PFA become extremely electrostatically charged on their surface when paper slides on them. It can thus occur that the electrostatic forces generated in this way hinder further transport of the paper web 17.
  • Such electrostatic charges can be prevented by adding electrostatically conductive substances, for example graphite or similar materials, to the toner-repellent layer 30. If the toner-repellent layer 30 consists of a layer glued to the preheating saddle, it is necessary to also make the adhesive conductive, in order to establish a conductive connection to the preheating saddle, which is expediently grounded.
