Definitions

  • the invention relates to a non-mechanical printing or copying device according to the preamble of claim 1.
  • Non-mechanical pressure devices such as Representing laser printers are generally known and have been used successfully.
  • a latent image is generally produced with the aid of a laser or magnetic recording media on a photoconductor drum or a magneto-sensitive drum, which is developed by applying toner in a developer station and then transferred to a tape-shaped recording medium in the subsequent transfer printing station.
  • the image which is loosely located on the recording medium and consists of toner, is fixed with the aid of a fusing device, e.g. is known from DE-0S 27 17 260, fixed.
  • the tape-shaped recording medium is then deposited on an automatic paper stacker.
  • the object of the invention is to design a non-mechanical printing or copying machine of the type mentioned at the outset in such a way that it is suitable for both reverse side printing and multicolor printing.
  • the back side printing is made considerably easier if you have a turning device between two devices in the paper guide channel, e.g. can consist of a simple deflecting element, arranges.
  • the individual devices are made up of fixing modules and printing unit modules that can be coupled to one another, this results in a particularly advantageous and simple construction of the entire printing system.
  • Connect two printing unit modules with the help of a simple hinge. This makes switching between multi-color printing and back printing particularly easy.
  • a deflecting rod which e.g. can already be integrated in the printer module, the printing system can be switched from multi-color printing to back printing.
  • Several printing unit modules have a fixing station arranged at the end of the printing system.
  • the deflection device arranged between two devices or two printing unit modules consists of a simple inclined deflection element formed from a rod, which is located within the paper entry area of the pa pier web receiving printing unit or device from a the paper web turning position into a position redirecting the paper web is designed to be pluggable. This means that the device can be easily converted for a wide variety of functions and used as a single device when the rod is removed.
  • the paper web is guided between the individual devices in a tread-resistant tunnel.
  • This tunnel has a paper length compensation device in the manner of a loop puller in the paper entry area of the device receiving the paper web.
  • This paper length compensation device consists of a stationary deflection roller and a second motor-driven deflection roller between a rest position and a paper insertion position.
  • the motor-driven deflection roller is simply moved out of the paper entry area of the device receiving the paper web.
  • the motor constantly generates a restoring force which acts on the second deflection roller and with which the paper is tensioned.
  • Scanning contacts arranged in the displacement area of the second deflection roller are linked to a warning device or control device.
  • a warning device or control device E.g. As a result of an asynchronous run of both devices, the paper length is too short, the second deflection roller is pressed against the front scanning contact as a result of the paper length arrangement and this is triggered.
  • the second contact roller triggers the rear contact.
  • Two printer modules or devices operated simultaneously can be synchronized in a simple manner in that, according to an advantageous embodiment of the invention, clock disks with scanning devices are provided in the area of the paper transport devices of the individual devices.
  • the signals emanating from the scanning devices are jointly fed to an up-down counter, which in turn is connected to an evaluation device designed as a simple comparison device.
  • the counter reading of the up-down counter device is a measure of the synchronous operation of the devices, whereby if the devices drift apart beyond a tolerable amount, one of the two devices is stopped by the evaluation device.
  • a drum 10 with a photoconductive surface is uniformly charged with the aid of a corona charging device 11. Then with the help of a character generator 12 e.g. of a controlled light beam from a laser, charge images generated on the drum 10. The charge images are then processed in a developer station 13 e.g. developed according to the magnetic brush principle. In a transfer station 14 the toner images now arranged on the surface of the drum 10 are applied to image receiving material 15 e.g. transfer a paper web as the final record carrier.
  • image receiving material 15 e.g. transfer a paper web as the final record carrier.
  • the image receiving material 15 is brought up to the surface of the drum 10. It is then passed through a fixing station 16.
  • the structure of station 16 is e.g. described in more detail in DE-05 28 38 864.
  • the fixing station 16 initially consists of a container 17, the bottom surface of which is arranged a heating device 18. A solvent located at the bottom of the container 17 is evaporated by heating. In order to prevent the solvent vapor from escaping from the container 17, cooling coils 19 are arranged in the upper region of the container. In this area, condensed solvent vapor drips back to the bottom of the container.
  • the image-receiving material 15 is guided through the container 17 with the aid of a guide roller 20. If it is to be fixed, the guide roller 20 is in position I, so that the image-receiving material 15 is in the area of the solvent vapor, which can act on the toner image attached to it. During the breaks in operation, it is advisable to remove the image-receiving material 15 from the area of the solvent vapor.
  • the guide roller 20 is moved upward in the container 17 and brought into the area of the cooling coils 19, specifically into position II. After the paper web 15 has passed through the fixing station, it is stacked with the aid of paper transport rollers 21 via an appropriate stacking device.
  • paper deflection rollers designed at least in the fixing station according to FIG. 2 are used. These very low inertia paper deflection rollers consist of a rigid foam body 22 made of polymethacrylimide, onto which a masking tape 23 having a large number of individual spike-like plastic elements is applied. This construction results in a low-mass paper deflecting roller with low thermal conductivity, so that no solvent vapor can condense on the surface of the fixing roller (guide roller 20). This prevents wiping when starting or braking the paper web 15 and a corresponding offset printing effect.
  • a laser printer constructed in this way can now be redesigned in accordance with the invention for reverse printing.
  • the fixing station is only indicated schematically in the examples described below. 2
  • a first printer 30 is coupled to a second printer 31 such that the recording medium 15 emerging from the paper exit area 32 is fed to the paper entry area 32 of the second printer 31 via a coupling device.
  • the two printers 30 and 31 are operated simultaneously and are synchronized via a synchronization device to be described later.
  • the printers 30 and 31, which are set up at right angles to one another, are coupled via a coupling device which consists of a tread-resistant tunnel 33 which receives the paper web.
  • a coupling device which consists of a tread-resistant tunnel 33 which receives the paper web.
  • the cover 34 of the tunnel 33 is designed to be hinged.
  • the tunnel serves both as a guide element for the paper web and as protection for the paper web between the two printers 30 and 31.
  • the tunnel is accessible and has a non-slip mat on its surface.
  • the deflection device In the paper entry area 29 of the subsequent, paper-receiving printer 31 there is a deflection device which turns the paper web 15.
  • the deflection device consists of a round rod 35 with bevelled ends having a latching opening.
  • the locking openings of the round rods 35 work together with corresponding locking lugs 36 in the paper entry area 32.
  • the round bar 35 is designed to be detachable in the paper entry area 32.
  • the position shown in FIG. 3 corresponds to the "backside printing" function. 6 (solid representation of the round rod 35), the round rod 35 is movably guided in the side walls of the paper entry area 32 in the function of the reverse side printing.
  • the position of the paper web is adjusted with respect to the edges of the individual forms of e.g. pre-folded paper. This position adjustment for the positioning of the individual holders is primarily necessary due to the turning of the paper web when printing on the back.
  • FIG. 4 das-dotted representation of FIG. 6 for two-color printing
  • the round rod 35 is firmly locked in the holding element 39 by means of locking lugs 36.
  • two paper deflecting rollers 40 and 41 serving as straight guide elements are arranged above the round rod 35 in the paper entry area 32 of the printer 33. 3, after the deflection by the round rod 35, the paper web 15 is guided directly over the paper deflection roller 40 to achieve back-side printing. To achieve two-color printing - in which a turning of the paper web is not provided for single-sided printing - after deflection by the round rod 35, the paper web 15 is first guided over the paper deflection roller 41 and then over the paper deflection roller 40.
  • the paper deflection roller 41 is in accordance with the illustration of FIG Fig. 6 slidably mounted.
  • the position of the paper deflection roller 41 can thus be adapted to different operating states.
  • the position of the paper deflecting roller 41 in operation with the round rod removed, ie in normal single-sided printer operation, is different than in single-sided two-color printing operation according to FIG. 4.
  • a paper length compensation device in the manner of a loop puller is located in the tunnel area 33 below the paper entry area 32 of the printer 31 for paper length compensation and to facilitate the insertion of the paper web.
  • the paper length compensation device is arranged in an advantageous, space-saving manner below the actual frame of the printer 31.
  • this paper length compensation device can also be arranged in the paper exit area 32 of the printer 30. It consists of a fixedly arranged first deflection roller 42 and of a second deflection roller 43 which is longitudinally displaceable between a rest position and a paper insertion position via a motor 43 and cables 45.
  • the deflection roller 43 is supported on one side on a guide rod 47, on the other side runs they, for example, via roller bearings 48 directly on the floor.
  • the second deflection roller 46 In the displacement area of the second deflection roller 46 there are scanning elements 49 and 50 designed as switches. 6 serve to trigger a warning device 51 or as a transmitter for an evaluation or control device 55. If, for example, the paper web between the two printers 30 and 31 is too long, the second deflection roller 46 moves to the rear Stop in the area of switch 49.
  • the motor 43 In order to generate a constant paper tension on the paper web, the motor 43 is constantly in frictional engagement with the cable pulls 45 during printer operation with a continuous paper web and thus constantly exerts a tensioning force on the paper web in the direction of the rest position. If the paper web is too short, the second deflection roller 46 is pulled through the paper web 15 into the vicinity of the position of the scanning element 50 and the warning device (lamp) is actuated and the first printer 30 is stopped. To insert the paper web, the motor 43 and thus the second deflection roller 46 can be controlled directly via the printer controls.
  • the second deflection roller 46 is moved from the rear position into the threading position shown in dashed lines to insert the paper.
  • the working rhythm and timing of such devices generally allow sheet-synchronous operation - which would enable a constant paper length between the devices - for reasons related to the principle, the inevitable start and stop processes cannot be fully synchronized in the meantime.
  • These adjustment processes which are unavoidable in the start and stop process, are compensated for by the paper length compensation device described, the automatic tensioning via the second deflection roller 46 permitting optimal handling when the paper web is inserted.
  • scanning devices 52 and 53 are located in the area of the paper feed as shown in FIGS. 3 and 4. These scanning devices 52 and 53 consist of conventional clock disks which engage in perforations of the paper web 15 and which have appropriate scanning means be scanned. They generate a synchronizing signal per line - however the print is made sheet by sheet.
  • the synchronization signals - which consist of individual pulses - of the scanning devices 52 and 53 are given to an up-down counter 54 as shown in FIG. 6.
  • the two incoming pulse quantities are subtracted from one another in this forward-backward counting device, so that the difference sum clearly shows which of the two printers, e.g. is in the lead or lag.
  • a synchronization tolerance range can be defined by specifying an absolute amount for the counter reading. If this synchronization tolerance range is exceeded, then according to the sign of the differential amount of the pulses originating from the up-down counter 54, a corresponding e.g. Evaluation device 55 designed as a comparison device stopped one of the two printers 30 or 31. In this case, the printer control device 56 controls the printer receiving the paper web 15 such that the single sheet currently being printed is still being written to the end. This ensures synchronization between the leaf gaps.
  • the individual printing or copying devices are designed in a modular manner, in such a way that the fixing station is accommodated in a special fixing module 57 and the actual printing unit containing the transfer station is accommodated in a special printing unit module 58, whereby modules 57 and 58 solve are connected to each other bar and connectable, so there is a particularly simple structure for both multi-color printing and for back printing. If, for example, two-color printing is desired in accordance with FIG. 8, then two printing units 58 which are filled with differently colored toner are simply coupled to one another and these printing unit modules 58 are connected to a common fixing station 57.
  • the two printing unit modules 58 are connected on one side via hinges 59, then starting from the two-color printing according to FIG. 8, they can be pivoted apart simply. by 90 ° in accordance with FIG. 9 for the reverse side printing.
  • a deflection rod 60 is fixed as the deflection element. This deflecting rod 60 can be fastened within the swivel range of the two printers 30 and 31 such that it is automatically brought into the working position shown when the printing system is swung apart.
