Definitions

  • the invention relates to a turning device for tape-shaped recording media arranged within an electrographic printing device.
  • EP-B1-01 54 695 To produce multicolor and reverse side printing with continuous-paper electrographic printing devices, it is known from EP-B1-01 54 695 to operate two continuous paper printers in succession, the paper printed in the first printer being turned over and subsequently printed in the second printer on the second side .
  • the aim of the invention is therefore to provide a turning device for tape-shaped recording media which enables automatic threading of the recording media.
  • Another object of the invention is to design the turning device in such a way that it can be arranged in a user-friendly manner in an electrographic printing device with which printing on one and both sides of a tape-shaped recording medium is possible.
  • Deflection elements arranged in the form of the letter W in conjunction with a motor-driven rotating gripping element enable a compact and reliable construction of a turning device with automatic threading of the record carrier.
  • the turning device can be used between two separate devices or integrated in one device. Due to its compact design as a self-supporting, slidably suspended structural unit, it is particularly suitable for integrated arrangement in multifunctional electrographic printing systems which, due to their structure, can print on continuous paper both on one side and on both sides, in one color or multi-color.
  • the transfer printing station and the fixing station have a usable width of at least twice the bandwidth of the recording medium, with each of these units being run through twice in duplex mode by the recording medium, in parallel next to one another.
  • the turning device is arranged downstream of the fixing station and can be coupled to the transfer station via the paper outlet channel. The turning device thus has two tasks: on the one hand it rotates the recording medium by 180 °, on the other hand it displaces the recording medium running out of the fusing station laterally by a recording medium width so that the subsequent transfer printing station and again the fusing station can be run through in parallel.
  • deflecting elements in the form of hollow rods, which are connected to one another, enables integrated air guidance in order to produce a friction-reducing air cushion in the area of the sliding surfaces of the deflecting elements.
  • the paper guide surfaces are designed to be pivotable, in particular in the region of the deflection elements.
  • a conveyor belt which is guided around the outer turning elements and has a friction lining on its inside as the threading element.
  • the friction lining is positioned between the inclined deflection elements in such a way that it is out of engagement with the recording medium.
  • the conveyor belt is guided at a distance around their sliding surfaces, whereas the recording medium slides along the sliding surfaces. The position of the record carrier relative to the friction lining thus changes prematurely. It is thus possible, at the end of the threading process, to push the beginning of the recording medium far beyond the rear end of the friction lining into the paper exit channel, where it is gripped by paper transport elements.
  • An electrographic printing device for printing on tape-shaped recording media 10 of different bandwidth contains an electromotive-driven photoconductor drum as intermediate media 11.
  • a band-shaped intermediate carrier e.g. use an OPC tape or a magneto-styli arrangement, e.g. is described in EP-B1-0 191 521.
  • the various units for the electrophotographic process are grouped around the intermediate carrier 11.
  • a charging device 12 in the form of a charging corotron for charging the intermediate carrier 11; a character generator 13 with a light-emitting diode comb for character-dependent exposure of the intermediate carrier 11, which extends over the entire usable width of the intermediate carrier 11; a developer station 14 for coloring the character-dependent charge image on the intermediate carrier 11 with the aid of a one- or two-component developer mixture; a transfer printing station 15, which extends over the width of the intermediate carrier 11 and with which the toner images are transferred to the recording medium 10.
  • a cleaning station 16 is provided with a cleaning brush integrated therein with the associated suction device and a discharge device 17.
  • the intermediate carrier 11 is driven by an electric motor and moved in the direction of the arrow in printing operation.
  • the printing device contains a fixing station 18 which is arranged downstream of the transfer printing station 15 in the transport direction of the recording medium and which is designed as a thermal printing fixing station, with a heated fixing roller 19 Associated pressure roller 20, and guide rollers 21 arranged downstream of the fixing station, which serve, among other things, as output elements for a stacking device 22 for the recording medium 10.
  • a fixing station 18 which is arranged downstream of the transfer printing station 15 in the transport direction of the recording medium and which is designed as a thermal printing fixing station, with a heated fixing roller 19 Associated pressure roller 20, and guide rollers 21 arranged downstream of the fixing station, which serve, among other things, as output elements for a stacking device 22 for the recording medium 10.
  • the fixing station shown other fixing stations are also possible, for example with a heated or unheated inlet saddle or a cold fixing station.
  • the tape-shaped recording medium 10 is made up, for example, as prefolded, continuous paper provided with edge perforations and is fed from a storage area 23 to the transfer station via feed rollers 24.
  • the transport of the record carrier is preferably carried out via a transport device 25 assigned to the transfer printing station 15 in the form of conveyor belts provided with pins which, guided by drive shafts 27, engage in the perforations on the edge of the record carrier 10.
  • a transport-hole-free recording medium an adapted transport device familiar to the person skilled in the art is to be provided which e.g. transported by friction, controlled by a control arrangement scanning synchronization marks.
  • a turning device 28 is arranged in the housing area of the printing device between the storage area 23 and the fixing station 18, the function of which will be explained later and via which the recording medium is returned from the fixing station 18 to the transfer printing station 15.
  • the printing device is controlled by a printer controller, which is shown schematically here, with a central unit CPU, a page memory SP, which is subdivided into memory areas depending on the page, and a data control unit DC. All control units are connected to each other and to the units of the printing device via a BUS system.
  • the electrographic printing device is suitable for printing on recording media with different bandwidths.
  • the intermediate carrier 11 (photoconductor drum) has a usable width which corresponds to the largest possible recording medium width (e.g. a format DIN A3 landscape). This width corresponds to twice the A4 bandwidth. It is thus possible to arrange two A4 recording medium widths alongside one another in the area of the transfer printing station 15.
  • the fixing station 18 and the other electrophotographic units, such as developer station 14, character generator 13, cleaning station 16, are designed in accordance with this usable width. Adapting the width of the character generator 13 to different recording medium widths does not require any mechanical change to the character generator if, as in this case, an LED character generator is used with a large number of LEDs arranged in rows. An adaptation to the recording medium width used is carried out electronically by control.
  • the transport device can be designed to be width-adjustable. This can e.g. can be achieved in that the drive wheels, which carry the conveyor belts (nubbed belts) engaging in the perforations on the edge of the record carrier, are displaceably mounted on polygonal shafts.
  • these transport elements do not interfere with operation with only one wide recording medium, they can be arranged such that they can be plugged in and plugged in or swiveled out, or it is possible to provide the drive wheels 27 of the transport device 25 with retractable pins and knobs.
  • the turning device 28 arranged in a return channel for narrow record carriers from the fixing station 18 to the transfer printing station 15 serves for rotating the record carrier from the front to the back. It is designed to be switchable depending on the operating mode and has an automatic threading device for the recording medium.
  • the narrow, for example A4-wide, recording medium is fed from the storage area 23 via the feed rollers 24 to the transfer station 15 and printed on its upper side with a front-side toner image.
  • the front of the record carrier 10 is identified by solid transport arrows, the underside by dashed transport arrows.
  • the recording medium with the front-side toner image is then fed to the fixing station 18 and the front-side toner image is fixed.
  • the recording medium is transported further to the turning device 28, the deflection contour of which is positioned in a turning position.
  • the record carrier is turned with respect to its front and back and fed again via the feed rollers 24 to the transfer printing device 15 in such a way that its back can be provided with a back toner image. Then the recording medium is again fed to the fixing station 18 and the back toner image is fixed and then the recording media printed on both sides are stored in the stacking device 22.
  • the page memory SP contains storage areas VS for storing the front side image data and storage areas RS for storing the back side image data.
  • the data preparation takes place via the data control device DC, the data starting from a data source (HOST), e.g. can be supplied to an external data memory via an interface of the data control device DC.
  • HOST data source
  • the data of the individual pages to be printed are stored in the page memory SP, separately to the front VS and back RS in the corresponding memory areas.
  • the call of the data is then time-controlled so that the desired front-back assignment of the toner images on the recording medium is achieved.
  • the turning device 28 (FIG. 3) essentially contains four deflection elements arranged in the manner of the letter W, via which the recording medium 10 is guided starting from a paper inlet channel 30 to a paper outlet channel 31. Paper inlet channel 30 and paper outlet channel 31 are arranged side by side in one plane.
  • a recording medium 10 fed via the paper inlet channel 30 is first guided over a first oblique deflection device 32 which deflects the recording medium laterally.

  • Deflection rods 33 and deflection elements 35 have wear-resistant polished surfaces as deflection surfaces 38 (FIGS. 5, 6, 7) which serve as sliding surfaces for the recording medium 10 and which are encompassed at a distance from guide surfaces 40 forming a deflection channel 39.
