Definitions
- the invention relates to a transfer printing station with an electrostatic transfer printing device for transferring a toner image generated on an electrographic intermediate carrier to at least one recording medium in a transfer printing area of the transfer printing station, guide elements arranged in the transfer printing area for guiding the recording medium near the intermediate carrier during the transfer printing process, and with one arranged between the guide elements Pressure element which presses the record carrier against the intermediate carrier during the transfer printing process.
- Such a transfer printing station is known from US 5,400,125. It uses a leaf-shaped blade as a pressure element, which presses the edge of the tape-shaped recording medium against the electrographic intermediate medium, a photoconductor drum. Although relatively good practical results have been achieved with this solution, there are still some disadvantages.
- the blade-shaped pressure element is a wearing part, the service life of which is relatively short and requires frequent replacement. Since the blade edge of the pressure element rubs on the recording medium, there is considerable contamination in the transfer printing area due to toner abrasion and paper abrasion. If different web widths of the recording medium are used, a pressure element that is matched to this web width must be used.
- the blade-shaped pressure element creates irregularities in the electrostatic field in the transfer printing area; these irregularities can create streaks in the printed image. It is an object of the invention to provide a transfer printing station of the type mentioned in such a way that, on the one hand, non-uniformly deformed recording media of different thicknesses or readings during transfer printing are uniformly applied to the intermediate carrier to generate a high-quality print image and that, on the other hand, it is ensured in all operating states is that the pressure element does not come into contact with the intermediate carrier.
- the pressure element which is designed as a pressure roller or as a pressure rail and extends essentially over the entire width of the electrographic intermediate carrier, e.g. a photoconductor drum, is designed to be rigid and, in order to maintain a defined minimum distance between the pressure element and the intermediate carrier, has a spacer element which is supported on the intermediate carrier, preferably in the form of a support roller.
- the pressing force can be increased, so that even a recording medium provided with waves can be pressed smoothly against the electrographic intermediate carrier.
- the increased pressure force also means that no air cushion can form between the recording medium and the intermediate carrier, as has often occurred in the prior art.
- the pressure element is designed as a pressure roller, it rolls on the recording medium and there is only rolling friction between the recording medium and the pressure roller. Accordingly, the abrasion on the recording medium is reduced and the risk of contamination is small.
- the surface of the pressure element is electrically conductive and has a predetermined electrical potential, preferably ground potential. In this way, electrical charges which are generated on the surface of the recording medium by electrostatic charging are collected and dissipated to ground. A disturbance of the electrical field in the transfer area is avoided.
- a preferred embodiment of the invention is characterized in that the pressure element has two support rollers, the diameters of which are dimensioned such that a minimum distance between the pressure element and the intermediate carrier is not undershot.
- a preferred use of the transfer printing station is characterized in that the web has already undergone a transfer printing operation, that is to say it has been provided with a toner image and has been conveyed over a longer transport path and, if appropriate, has been subjected to heat setting. Due to the renewed heat setting, ripples and grooves can form on the recording medium, which can lead to a deteriorated print image.
- these waves and grooves are smoothed in the transfer printing area, so that the recording medium ger is in full contact with the intermediate carrier for the transfer of toner.

- FIG. 1 shows a part of an electrophotographic printing device which contains a transfer printing station shown schematically in the figure.
- This transfer printing station serves to transfer a toner image generated on a photoconductor drum 10 to a tape-shaped recording medium, in the present case a smooth or prefolded continuous paper 12.
- This process is known as transfer printing.
- the transfer printing takes place in the context of an electrophotographic process, in which the photoconductor drum 10 is first charged uniformly to approximately 500 V using a charging device (not shown) and then partially discharged to a range of approximately 70 V using a character-dependent exposure device. A latent character image generated in this way is then colored in a customary manner in a developer station (not shown) with the aid of a two-component mixture of toner particles and ferro-magnetic carrier particles.
- the toner particles are positively charged triboelectrically.
- a field is created between a developer roller of the developer station, which is at a basic potential of approximately 220 V, and the regions of the latent character image discharged to approximately 70 V, as a result of which the toner particles accumulate on the discharged regions.
- the toner particles are repelled from the unexposed area with a charging voltage of approximately 500 V.
- the toner image thus generated from loose toner particles is then transferred to the tape-shaped recording medium 12 with the aid of a strongly negative electrostatic field generated by a corrotron wire 14.
- the corrotron wire 14 is shielded on one side by a corrotron screen 16; its electrical field acts through the opening gap between two transfer printing jaws 18, 20 through the recording medium 12, as a result of which the toner particles are detached from the photoconductor drum 10 and transferred to the recording medium 12 in contact with the photoconductor 10, where they adhere electrostatically.
- the toner images thus transferred are then melted into the surface of the recording medium 12 in a thermal printing fixing station (not shown) between a heated fixing roller and a pressure roller.
- two transfer printing jaws 18, 20 are provided as guide means, which are shown in FIG. 1 in the state in which they are pivoted towards the photoconductor 10. If no transfer printing operation is to take place, these transfer printing jaws 18, 20 can be pivoted away from the photoconductor drum 10, the recording medium 12 being carried along.
- the type of drive of the transfer printing jaws 18, 20 and the associated transport devices for the recording medium 12 are described in more detail in US Pat. No. 4,131,358.
- the end 22 of the transfer printing jaw 18 feeding the recording medium 12 plays a critical role in the prior art.
- the feeding direction for the recording medium 12 results from the movement of the photoconductor drum 10, as indicated by an arrow P1.
- This end 22 cannot be brought into intimate contact with the photoconductor drum 10, since the risk of damaging the sensitive surface of the photoconductor drum 10 is too great.
- the recording medium 12 must have this contact with the surface of the photoconductor drum 10 in order to transfer the toner particles. If the carrier material has minor defects or unevenness, these have a particularly critical effect at the end 22, so that the transfer of toner particles does not take place evenly.
- air bubbles can form between the underside of the recording medium 12 and the surface of the photoconductor drum 10, which lead to loss of contrast or even to a prevention of the toner transfer.
- out-of-roundness and waviness of the cylinder surface of the photoconductor drum 10 have a negative effect, since the distance between the end 22 and the surface of the photoconductor drum 10 fluctuates.
- FIG. 2 shows a solution from the prior art, as described in US Pat. No. 5,400,125 by the same applicant.
- the known solution uses a blade-like pressure element 24, which is arranged at the end 22 of the transfer printing jaw 18 and with its blade edge produces a defined contact between the recording medium 12 and the surface of the photoconductor drum 10.
- This solution has proven itself in practice, but there are disadvantages that the pressure element 24 wears out over time and has to be replaced, as a result of which the printing process is disturbed. With a high degree of wear of the pressure element 24, print image errors occur. Furthermore, abrasion occurs on the pressure element 24 and on the recording medium 12, which leads to contamination and a further source of interference.
- FIG. 3 shows an exemplary embodiment of the invention in a perspective view, the same parts denoting the same are not.
- a pressure roller 26 is mounted on the transfer printing jaw 18 and extends over the entire length of the photoconductor drum 10.
- support rollers 28 are attached, which rotate together with the transfer roller 26.
- the transfer printing jaw 18 can be pivoted about an axis of rotation 19 away from the surface of the photoconductor drum 10 and pivoted back towards it, the pressure roller 26 executing movements according to the arrows P2 and P3.
- the support rollers 28 have a diameter which is dimensioned such that they roll on the outermost portions of the surface of the photoconductor drum 10 during the transfer printing process.
- the radius of the support rollers 28 must be slightly larger than the sum of the radius of the pressure roller 26 and the thickness of the recording medium.
- the difference between the radii of the support roller 28 and the pressure roller 26 should be approximately 15/100 mm ⁇ 10%.
- the support rollers 28 ensure that on the one hand the recording medium 12 is brought into a defined vicinity of the photoconductor drum 10, the rolling friction between the recording medium 12 and the pressure roller 26 being minimal.
- the support rollers 28 have the effect that, even in the case of a recording medium 12 whose width is less than the length of the photoconductor drum 10, as seen in the longitudinal axis, the light-sensitive surface is not damaged. Any web widths can therefore be re-printed, which is particularly advantageous if the photoconductor drum 10 is long.
- the recording medium has two tracks 12A and 123 which are arranged next to one another.
- the transfer station shown is therefore suitable for use in a so-called duplex operation, in which a web of the recording medium is on one side Side is printed, then the web is turned 180 ° after heat-setting and fed to the same transfer station with the other side and then transferred.
- a first web 12A which has not yet been printed and a web 12B which has already been printed are fed to the transfer printing station.
- the already printed web 12B often has waves and a different surface finish due to the heat setting.
- the pressure roller 26 now ensures that even with two adjacent webs with different surfaces and different properties, both webs nevertheless lie evenly and smoothly on the surface of the photoconductor drum 10, so that perfect transfer printing can take place. Since the support rollers 28 roll on the surface of the photoconductor drum 10, deviations from the shape of the ideal cylindrical shape do not have an effect; rather, the pressure roller 26 is always kept at the same distance from the surface of the photoconductor drum 10 even if it is out of round and wavy.
- the width of the transfer printing jaw 18 and the pressure roller 26 and the length of the photoconductor drum 10 is typically dimensioned such that two DIN A4 webs in width format can be printed over side by side at the same time.
- the arrangement with the pressure roller 26 also proves to be advantageous in other operating modes, for example in simplex printing with adjacent recording medium webs and spot color printing without turning the recording medium webs or in duplex printing on a paper web with two printers which are coupled via a turning station.
- the pressure roller 26 has a conductive surface, for example made of metal. This conductive surface is electrically connected to ground potential, as indicated at 30 in FIG. 3.
- Figure 4 shows an illustration of the embodiment of Figure 3 seen from the side. It can be seen that the support rollers 28 have a slightly larger diameter than the pressure roller 26 itself.
- FIG. 5 shows a further exemplary embodiment of the invention
- the right transfer printing jaw 20 has a protruding guide end 34.
- the pressure roller 26 is arranged on the transfer printing jaw 18, as can be seen in FIG. 5, instead of a guide end.
- a pressure spring 36 biases the pressure roller 26 in the direction of the photoconductor drum 10. Due to the defined pressure by the pressure roller 26, there is a relatively large angle ⁇ in which the recording material 12 is in contact with the surface of the photoconductor drum 10. This large angle ⁇ has the effect that the transfer of toner particles onto the recording medium 12 takes place uniformly and without fluctuations in the distance between the carrier material 12 and the surface of the photoconductor drum 10. In this way, high print quality is achieved.
- FIG. 6 shows an arrangement in a conventional manner, without a pressure roller.
- the angle ⁇ in which there is contact between the recording medium 12 and the surface of the photoconductor drum 10, is significantly reduced.
- FIGS. 7 to 9 show a further advantageous example of a transfer printing station, in which a pressure rail 36 is arranged instead of the pressure roller.
- the pressure rail 36 is part of the transfer printing jaws 18, 20 and consists of a profile made of polished steel with a sliding surface 37 formed thereon for the recording medium. It extends over the entire width of the writable area consisting of a photoconductor drum 10 Intermediate carrier.
- Support rollers 28 are arranged on both sides of the pressure rail and are rubber-coated on their circumference. They interact with corresponding areas of the photoconductor drum which are arranged outside the actual writing area. Due to the profile, the pressure rail is particularly rigid. The more rigid the profile of the pressure rail, or in the case of the exemplary embodiment in FIG.
- the sliding surface 37 has a large feed radius, in particular in the area of the transfer printing jaw 18, which feeds the recording medium 12 to the transfer printing area.
- the recording medium 12 is thus transported almost tangentially to the radius of the photoconductor drum 10 to the transfer printing area. In this way, it is possible, as shown in FIG. 8, for the pressure point 38 of the recording medium 12
- the pressure rail 36 with the support rollers 28 can be a component of both transfer printing jaws 18, 20, so that the recording medium 12 is guided particularly well in the area of the transfer printing point or else only part of the transfer printing jaw 18, which feeds the recording medium to the transfer printing location. It is also possible, analogously to the exemplary embodiments with a pressure roller, to arrange the pressure rail 36 separately from the transfer printing jaws 18, 20. Due to the extremely rigid pressure rail 36 in connection with the support rollers, it is possible to maintain and guarantee a very narrow transfer gap (paper transport gap) of, in this case approximately 0.15 mm between transfer pads 18, 20 and photoconductor drum 10. The support rollers prevent damage to the photoconductor drum 10 in the event of paper tear and lack of paper.
- the transfer printing jaws 18 and 20 are mounted so as to be pivotable (arrows) about axes of rotation 44. They are supported by lever arms 40 and rollers 41 arranged thereon under the action of a tension spring 42 on an eccentric 43 designed as a cam disk. By turning the eccentric 43, the transfer printing jaws 18, 20 with the pressure elements 36 arranged thereon are pivoted.
- the tension spring 42 on the one hand ensures contact with the eccentric, in particular when swiveling, on the other hand, it presses the recording medium 12 against the photoconductor drum 12 by means of the pressure rails 36 or their sliding surfaces 37, the support rollers 28 preventing the transfer gap width from falling below.
- the transfer printing jaws are thus displaceably mounted relative to the surface of the photoconductor drum 12 against the spring force of the spring 42, so that recording media of various thicknesses can be processed.
