Definitions
- the invention relates to a method and an apparatus for Transport of pre-printed, web-shaped record carriers, especially of continuous paper in an electrographic Printer. It can be used as a web-shaped recording medium Paper, foil, labels, or other materials be used.
- a wide variety of paper types can be found when printing on paper Application.
- high performance electrographic printing with printing speeds of more than 40 pages per minute mainly so-called punched paper is used.
- This Paper has lateral holes on its longitudinal edges for transport and for position monitoring of the paper. It will be there driven by caterpillars in the side transport holes intervention. Often this paper also has cross perforations, along which the individual sides of each other be separated.
- the edge perforation is used in particular when processing pre-printed paper.
- the im information subsequently applied to an electrographic printer For example, data on a preprinted form be printed, as precisely as possible at specified points on the Forms come to rest.
- the Position of the paper web in the transport direction exactly on its drive or adjusted to the movement of the photoconductor drum or be synchronized.
- a printer that is used to process roll paper without perforations is suitable, for example, in the WO 95/19929 A1.
- a first contact edge is provided in this printer, the specifies the lateral position of the paper, as well as stabilizing rollers, a vacuum brake and a roller assembly with a loop puller.
- tractor-less friction drives there is the problem with tractor-less friction drives, that the transport accuracy in the feed direction is not always can be adhered to exactly. You can do this, for example Slip between the drive roller and the paper web or Manufacturing tolerances of drive mechanics contribute.
- Switching between these two speeds can be controlled by a sensor which is an edge of the record carrier web detected at a certain position.
- a sensor which is an edge of the record carrier web detected at a certain position.
- the object of the invention is a method and an apparatus for controlling a tractorless drive for web-shaped Specify record carriers with which preprinted record carriers can be transported precisely.
- the invention provides for the front edge of the pre-printed, marked path of the record carrier in an input area of the printer to a predetermined one Create inlay mark. Then the record carrier web from a transport motor with a first, relatively low speed along a direction of transport transported by a predetermined length. there a sensor scans a predetermined area of the paper and sends scanning signals to an evaluation device. This evaluates the signals and checks whether they match a given one Brand are assignable. The one between two successive ones The length of the transport is then marked by the evaluation device identified as a value for a side length. Finally, the printing process with a second, relative high transport speed initiated and with the identified Side length value controlled.
- the drive for the Path of the record carrier after one page feed is synchronized to the side length. position error the web caused by inaccurate insertion of the paper web or occur due to increased slippage between the drive and the web, are compensated for on the first print page.
- the invention also makes it possible to use recording medium webs, which contain indefinite forms, exactly in position to transport.
- the forms can, for example in terms of type, color, shape, Size (length) or the position on the record carrier to be indefinite.
- the regulation only needs a negligible Time to settle in. Waste, i.e. excess unprinted paper is largely avoided.
- Already With the first print page printing is carried out in the correct position within the form.
- the senor is placed on the markings and / or on the Background of the markings sensitized. Furthermore it is advantageous to move the sensor transversely to the recording direction to arrange. The mark can then be on any Place of the form. Even parts of the form like texts, graphics or window sections then be used as a brand.
- the sensor of the invention is So adaptable to the respective form content by clicking on selected information is sensitized.
- the sensor is preferably sensitized by the paper at least once in and against the direction of transport is transported, during this Vorund Backward movement checked by the evaluation device whether and when the sensor emits a signal. It can be provided that several cycles of forward and backward movements be carried out and that after each cycle Setting value on the sensor is changed. The finally determined Sensor setting values can then be saved and can be reused for later sensitization processes.
- a self-learning system can be created by a certain number at the start of an awareness-raising process the most frequently and / or most recently used setting values is used.
- the starting procedure according to the invention in particular achieves that printing begins with the first page can, that of the required to sensitize the sensor Page follows.
- the procedure according to the invention can be largely automated. There are therefore operational errors when loading the paper largely excluded or can be compensated. The process takes little time, which makes it effective Printer printing time is high.
- the printing device shown in Figure 1 takes one web-shaped recording medium 5 made of paper from a paper input container 1 or from a supply roll 11.
- the paper web 5 is a loop 12 one Deflection device 2 supplied and then in a web pre-centering device 3 along a contact edge to friction drive rollers 4 led. Then it is from one Drive 8 pulled over a vacuum brake 6, which with a vacuum pump 7 is connected, which generates the negative pressure.
- the paper web 5 is braked by the negative pressure while increasing the tension of the paper web 5.
- the paper web 5 After the vacuum brake 6 the paper web 5 passes through a stabilization zone, the from several pulleys 9 and a loop puller 10 exists.
- the paper web 5 wraps around the deflection rollers 9 at least 180 °, which makes the paper web laterally wider is stabilized.
- a sensor arrangement 17 optically scans the paper 5.
- the Sensor arrangement 17 is designed so that it is the widest paper 5 that can be processed in the printer still over its entire length Can scan width.
- the width of the sensor arrangement 17 is both in the mechanical components for paper transport adapted as well as to the parameters on the recording side the printing device 14, which is the printable width establish. It is particularly the width of a photoconductor drum 16 adjusted.
- the paper width that can be processed is sufficient in the present embodiment from 6.5 inches (165 mm) to 19 inches (482.6 mm). Details of the sensor arrangement 17 are in the German patent application filed by the applicant described with the file number DE 197 49 676.8, the Contents hereby by reference in the present description is recorded.
- the paper web 5 is transferred from the sensor arrangement 17 via a drive unit 13 fed to a transfer station.
- the transfer station includes a in the illustrated embodiment Photoconductor drum 16, which with a Corotron device 16a interacts.
- the photoconductor drum 16 is known Way exposed by light with information, whereby a charge pattern is applied. Then takes They have a magnetized toner that is in the transfer printing area the paper web 5 is transferred. Then the unloads Corotron device 16a the corresponding area of the photoconductor drum 16 again, so this again with information can be described.
- Corotron device 16a acts in a manner known per se, such as in EP 0 224 820 B1.
- Figure 2 shows this in the area of the transfer station or the photoconductor drum 16 of the electrophotographic printer Drive unit 13 more precisely.
- a roller arrangement 20 also presses on the drive roller 40 given spring force. This will make it between the Rolls 40 and 20 transported paper 5 by friction (Friction) moved by the drive roller 40.
- the drive roller 40 is in turn via a toothed belt drive connected to the stepper motor 41.
- the entire drive unit 13 is flanged to a printer housing via the bearing block 44.
- On the bearing block 44 is through the ball bearing 43 common bearing axis 42 mounted, on the one hand, the rotary movement the drive roller 40 and the other one Swiveling movement of the drive elements about the swiveling axis B.
- the drive components are to enable the swiveling movement mounted on a support plate 47, which via a Gas spring 49 and via the bearing axis 42 with the bearing block 44 is connected.
- Threads 45 located in the bearing block 44 are used for receiving of fastening screws that are led through the printer housing become.
- the entire drive unit is over guide surfaces 46 adjustable within the printer housing.
- the carrier plate 47 is in turn adjustable with respect to the bearing block 44, a first adjustment screw 51 and a second Adjustment screw 52 are provided in the bearing block 44 strike the cylinder-side cylinder pins.
- the paper sensor 55 scans the paper 5 over the total width of the printable area of the photoconductor drum 16 from, whereby both the side paper edges as any edge perforations in the paper web 5 can also be recognized can.
- a well-known electrical Corotron device 57 generates a high voltage, through which the toner located on the photoconductor drum 16 is drawn to the paper.
- Deflection rollers 58 guide the paper 5 further to a mark sensor 59, the possible one, on the paper web 5 existing printing or cutting marks 109 recognized.
- Grounded electrical connections 61 anti-static sheets lead any, located on the paper 5 electrical Remaining loads.
- edge punched paper 5 is transported with the paper transport, the edge perforation can be scanned with a spike wheel 60 become.
- the speed of the paper web can therefore be impulsed 5 and their position in relation to the transport grid determine the drive device.
- the signals from sensor 85 are therefore used as input signals for anti-slip control of the paper drive used.
- the sensor assembly 89 is electrically connected to a device control ( Figure 5).
- FIG. 5 shows electronic control components of the printer as well as their interaction with the drive mechanics and Sensors.
- the drive unit 13 has a drive control 100 using a general data bus 112 a higher-level printer controller 101 is connected. about A control panel 105 can be used to enter commands from the operator become.
- the drive controller 100 receives the signals from the paper width sensor 17 or 55 via its interface 104. From this, it determines both the paper width and the Paper type, i.e. whether there are perforations around the edge.
- the drive control 100 also receives the scan signals from the spiked wheel sensor 85 via its electronics 103 and that of Brand sensor 59 via its electronics 107. From the signals of components 103 and 107 is in the drive control 100 calculates the speed of the paper web 5. The result becomes the anti-slip control of the stepper motor drive 102 used.
- the target speed signals will be delivered by the printer controller 101.
- the new paper web 5 is operated as follows:
- a paper web 5 is manually fed into the printer through the various Unit components up to the drive unit 13 moved in. There the front edge 110 of the paper web 5 up to the guide surface 69 in the area of the ruler 65 threaded.
- the paper web is fed in the area of the ruler 65 5 already via the drive motor 41.
- the operator determines the direction of the feed (forward / backward) by the The beginning of a page exactly to the length of the page Align the marking of the ruler 65.
- the feed takes place relatively slowly and in small increments.
- the transport steps are only a fraction of the grid spacing in the start mode, which is typically 1/6 inch (approximately 4.3 Millimeters).
- the step size is, for example 1/20 grid spacing (about 0.21 millimeters).
- the mode of transport is the speed with the spiked wheel sensor 85 or the position of the paper 5 detected and with the Speed or position of the drive motor 41 compared. Slip occurs, i.e. a discrepancy between these two speeds or positions determined and by the drive control 100 by additional Jacking (additional steps in the direction of transport) balanced.
- Insert marking 65a is provided on the ruler 65. Therefor different insertion instructions are possible. For example Depending on the side length, the insertion mark 65a can be Place the ruler 65. It can alternatively also be provided a common for different side lengths Provide insertion mark 65a on the ruler 65. Finally, the insertion mark 65a can also be placed directly below the sensor 59, i.e. at its sampling point. (Step S1). On the control panel 105 of the printer is then the pre-print underlying page length entered and the value stored in memory 106 (step S2).
- the forms pre-printed on the paper web 5 become then selected a certain piece of information, that as mark 109 should serve.
- This mark 109 can be a text as well graphic information, although it is also conceivable to change it Surface structure, for example one in forms stamped window cutout to use.
- the sensor 59 is adapted to the selected brand information.
- an optoelectronic Sensor 59 uses a high contrast sensitivity as well as color sensitivity.
- would you cut windows as brand information for example also a mechanical scanner or an ultrasonic sensor be suitable as a brand sensor 59.
- As a brand 109 should such information on the form be used which, based on the feed direction A, only once per Form page occurs. If it occurs more often, the evaluation electronics must 107 of the sensor 59 or the unit control 100 be able to do the repetitions within the Filter out side so that the drive is exactly on the Top of page information can be regulated.
- the information in which area of the form the Mark 109 lies is queried and possibly saved. hereby a window is specified within the form, by the sensor 59 responding to the brand information.
- the specification of a brand window also ensures that the brand information assigned correctly becomes, even if the same mark 109 multiple times occurs identically on a form page.
- the data transfer between control panel 105, higher-level printer controller 101 and unit control 100 takes place via the data bus 112.
- Step S9, S10 you move forward one step at a time, and the pedometer n increases by the value 1 (Steps S9, S10). Then it is checked again whether the next following mark 109 was recognized (step S11) if not, is advanced again and counted up, if so, then the value n is recorded as the current page length value and stored in the memory 106 (step S12). Subsequently a "ready to print" message is generated (Step S13). Before printing on the photoconductor drum 16 can be started, the paper 5 with the previously determined values for the side length and for the brand position still positioned correctly in relation to the photoconductor drum 16.
- step S19 the start procedure is step S8 continued. For this purpose, an instruction command "return to main "(step S20).
- the paper web 5 is processed to the exact page, whereby full pages are always printed. Slip between Drive 13 and paper web 5 is similar in this mode as recorded in the start mode, but not by additional feed, but by a higher speed of the drive motor 41 balanced. If paper 5 with Edge perforation is used, the edge holes are made by the pinwheel sensor 85 continuously sampled and the scanning signals used for anti-slip control. If paper 5 without Perforated edge is used, then the marking 109 is made page by page scanned and this scanning result for anti-slip control used. This side-by-side scanning can instead of or in addition to scanning the pinwheel sensor 85 can also be used with perforated paper 5. At this however, it is important that the drive 13 is so accurate that within one side End of page (or just before mark 109 on the next page) there are no excessive shifts in the printed image.
- the drive control 100 does not immediately Stop the drive, but a stop to the next page change. Through this measure, the assignment of Steps of the drive motor 41 to the scanned marks 109 very well preserved.
- the paper web 5 reinsert e.g. after a paper tear
- the paper web 5 becomes as follows first: the operator positions the new paper web 5 roughly in the insertion area at ruler 65. Then is the paper web 5 from the drive unit 13 with the first, at a slow speed until the mark sensor 59 detects a mark 109. Based on this determined brand position and the determined before the print stop Side length, the paper web 5 is again justified positioned to the printing station 14 and the printing process continued.
- start mode becomes the paper web 5 relative to the mark sensor 59 after identifying two successive brands 109 one or more times between the detected marks 109 transported back and forth.
- This can create dynamic conditions in the acceleration of the paper web 5 more precisely be determined and the drive control in the acceleration phase be further improved. In particular, it will an optimal speed curve of the drive is determined, is largely balanced by the slip.
- the drive control 100 With the signals of the paper width sensor 17, the drive control 100 also determine if and what kind of Paper is loaded in the printer. This is the drive motor 41 moved back and forth several times and the sensor signals evaluated. If one or more holes are recognized, see above a perforated paper web 5 is assumed. Based on the recognized Hole positions can then also be automatic alignment on the grid.
