Definitions
- the invention relates to a method and an apparatus for processing a tape-shaped recording medium with perforations in an especially electrographic printer.
- tape-shaped, perforated recording media are mainly used.
- the recording media are mostly made of paper and have long holes on their long edges for transport and position monitoring.
- the record carrier track is driven by caterpillars, which engage in the transport holes on the side.
- these record carriers additionally have transverse perforations, along which the individual pages can be separated from one another or folds, by means of which they can be folded up and stacked.
- a perforated paper web is usually fed in a specific grid that corresponds to the spacing between the holes.
- Usual paper webs have hole spacing of ⁇ inches.
- the feed can then take place, for example, in a 1/6 inch grid corresponding to 3 steps per hole spacing or in a 1/8 inch grid corresponding to 4 steps per hole spacing.
- Figure 7 shows such a paper web with perforated edges.
- This hole spacing a is the grid spacing of the hole spacings.
- the fold or the transverse perforation which define the top of the page, lies exactly in the middle between two edge holes, as illustrated for example by line 22.
- the fold or the transverse perforation can lie on one of the grid lines 23. The fold or cross perforation is then different with respect to the holes at each start of the page.
- FIG 8 shows the essential components of printers according to the prior art which are known for example under the trade name Oce Pagestream ®.
- a tractor drive 24 is provided in these printers. It comprises a stepper motor 26 which drives a tractor wheel 25; the spines engage in the edge holes 21 of the paper web 5.
- the stepper motor 26 is driven by an electronic controller 27 which on the one hand receives clock signals 30 from an image generation unit and on the other hand receives clock signals from a pickup 28 via the current stepper motor speed. These signals are formed by scanning a timing disk 29 connected to the drive shaft of the stepping motor.
- the clock disk signals correspond to a feed of 1/6 inch, ie exactly the transport grid.
- the controller 27 converts the image generation clocks 30 in a fixed frequency ratio into drive clocks 31 for the stepping motor 26, each of which causes a feed of 1/6-inch on the paper web.
- the drive is initialized after the printer is switched on. To do this, the tractor wheel 25 is first aligned to the 1/6 inch transport grid.
- the controller 27 generates drive cycles in steps of 1/240 inches until it receives a signal from the pickup 28 that a 1/6 inch mark of the clock disk 29 on the pickup 28 has been detected.
- the paper web 5 can continue in the 1/6 inch grid in this way.
- a reference point for example the fold 22, moves with every 1/6 inch step exactly from a 1/6 inch step mark on the fixed ruler 65 to the next 1/6 inch step mark.
- a marking of the paper web 5, for example the transverse perforation or the fold is then positioned in 1/6 inch increments on the corresponding side marking (10 ", 11", 12 "or 13") of the ruler 65 .
- the following pages are then automatically positioned exactly due to the forced guidance by the tractor caterpillar.
- Edge punching is used in particular when processing pre-printed paper.
- the information subsequently applied in the electrographic printer for example data which is printed on a pre-printed form, should be located as precisely as possible at predetermined positions on the form.
- the perforated paper is generally fed in a specific grid corresponding to the hole spacing, for example in a ⁇ inch grid or in a 1/6 inch grid.
- the paper web is gradually moved by a multiple of the grid spacing.
- a first contact edge is provided in this device, which specifies the lateral position of the paper, as well as stabilizing rollers, a vacuum brake and a roller arrangement with a loop puller.
- roll papers can now be processed both with edge perforation and without edge perforation via a tractor-less friction drive.
- the advantage here is that paper with edge perforation can still be processed, although this edge perforation is not used for transporting and guiding the paper. Papers with border perforation are often still kept in stock in printing centers or are already delivered pre-printed. Perforated roll paper should nevertheless be able to be used in a device that does not necessarily need the perforated edges for transport.
- the object of the invention is to provide a method and a device for controlling a tractor-free paper drive, with which edge-perforated continuous paper can be transported in the feed direction with high positional accuracy.
- a perforated recording medium in a start mode with a friction drive is first transported in steps of a first, smaller grid - the so-called control grid - until it is fitted into a second, larger grid, the so-called transport grid, which corresponds to a fraction of the hole spacing .
- the so-called transport grid which corresponds to a fraction of the hole spacing .
- any point marked on the record carrier e.g. a line, a transverse perforation or a fold, to lie in regular steps of the transport grid at predetermined positions, for example on markings on a ruler firmly connected to the drive.
- the transport perforation of the recording medium is scanned regularly, in particular continuously, and the scanning result is used to regulate the drive, in particular to compensate for any slip occurring between a friction drive roller and the recording medium.
- the perforated paper is transported in steps of the transport grid, the regulation being maintained on the basis of the scanning of the transport perforation.
- the invention is first determined whether paper with edge perforation or paper without edge perforation is inserted in the printer before the transport process is started in the control grid.
- the invention is particularly applicable in an electrographic printing or copying machine.
- step-by-step positioning leads overall to more precise positioning. Due to the gradual feed, especially in the start mode, incorrect positioning of the paper with respect to reference marks on the printer can be easily recognized. They can therefore be avoided more easily than with a continuous drive. Incorrect positioning then always leads to a deviation of at least one grid step. Such deviations can be easily recognized and corrected automatically by the operator on a grid ruler arranged in the area of the paper run, or automatically. This check or correction can take place at the beginning of the printing or paper loading process.
- the step-by-step movement is preferably carried out with a stepper motor, but in principle could also be carried out with other motors, for example with a correspondingly controlled DC motor.
- the invention provides that, in order to control the drive motor, sensor signals about the speed of the recording medium are compared with reference signals, which are preferably supplied by an exposure unit, but are at least synchronous with its clock, and that control signals are formed therefrom.
- control signals are preferably not necessarily clock-synchronized with the signals of the exposure unit, i.e. the two signals have no fixed frequency relationship to one another.
- the control can be fine-tuned independently of the exposure cycles of the imaging part of the printing device.
- the edge holes of the paper web can be scanned continuously in the start mode and in the normal mode.
- This is in particular a sensor arrangement is provided which engages in the edge holes and whose signals are used by a drive control for regulating the paper drive.
- This regulation particularly compensates for slippage between the paper drive and the paper web by additional feed or by adjusting the drive speed. This ensures that the printed image is transferred to the paper in the correct orientation.
- Unperforated paper can be scanned by a brand sensor with regard to pre-printed brands and a page brand located on the paper can also be transported to a predetermined feed position.
- the paper without edge perforation can be transported continuously and does not have to be transported with the increments of the transport of perforated paper.
- the sensor for scanning the edge perforation has, in particular, a resolution that is equal to or lower than the hole spacing of the recording medium.
- the current position of the transport perforation relative to the transport device can be determined directly from the sensor signals, possibly taking into account an adjustment offset of the sensor, and a quick start operating mode can be carried out.
- the record carrier web is advanced in steps of the transport grid until a page transition of the record carrier bears against a printer-proof side marking.
- This side marking corresponds in particular to the side length and is located on a ruler fastened in the drive unit.
- the electronic control makes it possible to process roll paper that has no border perforation in the same way as roll paper with border perforation, that is to say, for example, to gradually transport both, or paper without border perforation on other to be transported as perforated paper, for example driving one paper with completely stepless and the other at least partially in stages.
- the paper web is stopped in such a way that a predetermined position within a print page, in particular a page boundary, lies at a predetermined position on the record carrier transport path.
- the stop positions are always based on the grid specified by the peripheral perforations.
- the correct position of the print image with respect to the top of the page is then retained even after the print stop.
- the printing process can then be continued in particular with the next page, which minimizes the loss of material (waste).

- FIG. 2 the section through a drive unit
- FIG. 3 a view of the drive unit
- FIG. 4 a sensor arrangement
- FIG. 5 a block circuit diagram for controlling the drive
- FIG. 6 essential components of a drive
- Figure 8 Components of a drive according to the prior art.
- the printing device shown in FIG. 1 takes a tape-shaped recording medium (paper) from a paper input container 1 or from a supply roll 11.
- the paper web 5 is fed via a loop 12 to a deflection device 2 and then in a web Pre-centering device 3 fed friction drive rollers 4 along a contact edge. It is then pulled by a drive 8 via a vacuum brake 6, which is connected to a vacuum pump 7, which generates the vacuum.
- the paper web 5 is braked by the negative pressure and the tensile stress of the paper web 5 is increased. The higher the tensile stress, the more stable the paper web 5 runs in the transport direction A, ie the less it laterally slides out of the desired paper transport direction.
- the paper web 5 passes through a stabilization zone which consists of a plurality of deflection rollers 9 and a loop puller 10.
- the paper web wraps around the deflection rollers 9 by at least 180 °, as a result of which the paper web is further stabilized laterally.
- a sensor arrangement 17 optically scans the paper.
- the sensor arrangement 17 is designed such that it can still scan the widest paper that can be processed in the printer over its entire width.
- the width of the sensor arrangement is thus adapted both to the mechanical components for paper transport and to the recording-side parameters of the printing device 14, which determine the printable width. It is particularly adapted to the width of a photoconductor drum 16.
- the processable paper width in the present exemplary embodiment ranges from 6.5 inches (165 mm) to 19 inches (482.6 mm). Details of the sensor arrangement 17 are described in German patent application 197 49 676.8, the content of which is hereby incorporated by reference into the present description.
- the paper web 5 is fed from the sensor arrangement 17 via a drive unit 13 to a transfer printing station.
- the transfer printing station comprises a photoconductor drum 16 which interacts with a corotron device 16a.
- the photoconductor drum 16 is exposed to information in a known manner by light, where is applied by a charge image. Then it picks up a magnetized toner which is transferred to the paper web 5 in the transfer printing area.
- the corotron device 16a then unloads the corresponding area of the photoconductor drum so that it can be written with information again.
- the corotron device 16a acts in a manner known per se, as described for example in EP 0 224 820 B1. The contents of which are hereby also incorporated into the present description by reference.
- the sensor arrangement 17 is arranged in the area of the paper feed device 15, but it can also be provided within the printing unit 14.
- the paper web 5 is transported in the paper transport direction A.
- FIG. 2 shows the drive unit 13 arranged in the area of the transfer printing station or the photoconductor drum 16 of the electrophotographic printer in more detail.
- a roller arrangement 20 presses against the drive roller 40 with a predetermined spring force. As a result, the paper transported between the rollers 40 and 20 is moved by the drive roller 40 by friction (friction).
- the drive roller 40 is in turn connected to the stepper motor 41 via a toothed belt drive.
- the entire drive unit 25 is flanged to a printer housing via the bearing block 44.
- a common bearing axis 42 is mounted on the bearing block 44 by the ball bearing 43, which on the one hand absorbs the rotational movement of the drive roller 40 and on the other hand a pivoting movement of the drive elements about the pivot axis B.
- the drive components are mounted on a carrier plate 47, which is connected to the bearing block 44 via a gas pressure spring 49 and via the bearing axis 42. Threads 45 located in the bearing block 44 serve to receive fastening screws which are guided through the printer housing 18. The entire drive unit can be adjusted via guide surfaces 46 within the printer housing.
- the support plate 47 is in turn adjustable with respect to the bearing block 44, a first adjustment screw 51 and a second adjustment screw 52 being provided in the bearing block 44, against which cylinder-side cylinder pins strike.
- the gas pressure spring 49 is connected to the carrier 47 by the screw connection 50 and to the bearing block 44 by the screw connection 48.
- the carrier 47 and the bearing block 44 can be locked against one another with the locking device 54.
- a paper web which is inserted into the drive unit 25 between the drive roller 40 and the counter-pressure rollers 20, is guided by a guide plate 53 to a paper sensor 55.
- the paper sensor scans the paper across the entire width of the printable area of the photoconductor drum, whereby both the lateral paper edges and any perforations on the edges of the paper web can be detected.
- the paper is pressed against the surface of the photoconductor drum 2 by spring-loaded swivel jaws 56.
- a known electrical corotron device 57 generates a high voltage, by means of which the toner located on the photoconductor drum is drawn towards the paper.
- Deflection rollers 58 move the paper further to a mark sensor 59, which detects any printing or cutting marks present on the paper web.
- Grounded electrical connections 61 remove any residual electrical charges on the paper.
- FIG. 3 shows the paper drive 25 in a three-dimensional representation. This shows in particular the cylinder pin 66 mounted on the support plate 47, which cooperates with the adjustment screw 52 screwed into the bearing block 44, and the screw connection 50 of the gas pressure spring 49.
- the paper is guided by a guide surface 69 above the deflecting rollers 58. In this area, the paper is also scanned with the mark sensor 59. Furthermore, in this area, a contact ruler 65 is provided, which is used for starting the printer. Newly inserted paper, which has edge perforations, is placed with a top of a mark 65a of the ruler 65 corresponding to the side length, the edge perforation is brought into engagement with the pivoted barbed wire 60, and the printing process is initiated.
- the spike wheel 60 is part of a sensor arrangement, which is described in more detail in FIG.
- a drive motor 68 pulls a corotron wire corresponding to the page width to be printed from the corotron wire cassette 57.
- the mark sensor 59 can be displaced in the direction E along the rod 73.
- the plate 66 covers the drive motor 41 and is used in particular for electromagnetic shielding.
- a rear bracket 67 is also provided, which is also attached to the printer housing.
- FIG. 4 shows the pinwheel sensor 85, which includes the pinwheel 60.
- the spike wheel is pivoted away, ie the spikes do not protrude beyond the paper guide plane 67.
- this pinwheel can be pivoted in or out in the direction F.
- the pinwheel 60 is mounted on an axis 87, which also carries a gear 88.
- a magneto-resistive sensor 91 detects pulses from the metal gears of the gear 88. These pulses can be clearly assigned to the rotary movement of the pin wheel 60, so that the edge perforation of paper is thus scanned. gene that runs over the paper plane 67 and is in engagement with the Stachelrasd 60.
- the speed of the paper web and its position in relation to the transport grid of the drive device can consequently be determined from these pulses.
- the signals from sensor 85 are therefore used as input signals for anti-slip control of the paper drive.
- the sensor module 89 is electrically connected to a device controller (FIG. 5).
- a second magnetoresistive sensor 92 detects whether the pinwheel sensor 85 is in the pivoted-on or pivoted-off position with respect to the paper guide plane 67. For this purpose, it interacts with the magnet 93, which is mounted on the guide surface 67. The entire spiked wheel sensor 85 can be locked in the pivoted or pivoted-in position with a locking mechanism 90.
- FIG. 5 shows some electronic components of the printer.
- the drive unit 13 has a drive control 100, which is connected to the higher-level printer control 101. Commands can be entered by the operator via a control panel 105.
- the drive control 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, ie whether there are perforations in the edge.
- the drive control 100 also receives the scanning signals from the spiked wheel sensor 85 via the interface 103. From this, the speed of the recording medium (of the paper web 5) is calculated in the drive control 100. The result is used to control stepper motor drive 102.
- the target speed signals are supplied by the printer controller 101.
- a paper web with edge perforation is manually drawn into the printer through the various unit components up to the drive unit 13. There, the paper is threaded up to the guide surface 67 into the area of the ruler 65 and the edge perforation is brought into engagement with the spikes of the spiked wheel 82. In the area of the ruler 65, the paper is already fed by the drive motor 41.
- the operator determines the direction of the feed (forward / backward) in order to align the start of a page exactly with a marking of the ruler 65 corresponding to the side length.
- the operator can adjust the feed. It takes place relatively slowly and in transport grid steps that correspond to fractions of the hole spacing.
- the hole spacing is typically 1/2 inch (approximately 12.8 millimeters), the transport grid width is typically 1/6 inch.
- the speed or the position of the paper web 5 is already detected with the spiked wheel sensor 85 and compared with the speed or position of the drive motor 41. Slippage that occurs, i.e., a discrepancy between these two speeds or positions is determined and is controlled by the drive control 100 by additional propulsion, i.e. compensated by additional steps of the stepper motor in a control grid with a grid width of 1/120 inch.
- the relatively slow speed in the process just described serves to align and position a certain feature or a mark of the paper web 5 (for example a fold, a mark, a side transition or the like) on a marking 65a which is fixed relative to the paper drive unit 13 or on the ruler 65 described above.
- a certain feature or a mark of the paper web 5 for example a fold, a mark, a side transition or the like
- the operator With a gradual feed in the transport grid, the operator is positioned the paper web 5 much easier: an incorrect position would deviate from the target position by at least one transport grid width and could thus be easily determined visually.
- the paper web 5 is processed with precise pages, whereby complete pages are always printed. Slip between drive 13 and paper web 5 is also recognized by continuous scanning of the peripheral perforations 21. In this operating mode, the slip is compensated for by regulating the speed of the drive motor.
- the transport grid width is adapted to the side length of the perforated paper web 5.
- a transport grid width of 1/6 inch for example, side lengths of 3, 3 1/6, 3 2/6, 3 3/6, 3 4/6, 3 5/6, 4, 6, ..., 28 Inch processable to the page.
- the side length does not have to be a multiple of the transport grid width, but can be virtually any. Unperforated paper is therefore not transported in steps of the transport grid, but in any small steps up to continuous transport.
- the drive control 100 can also determine whether and what type of paper is loaded in the printer. For this, the drive motor is e.g. Moved back and forth several times and evaluated the sensor signals. If one or more holes are recognized, a perforated paper web is assumed. Based on the recognized hole positions, an automatic alignment to the hole pattern can then take place.
- stepper motor 102 adjusts the stepper motor 102 in small control steps corresponding to a 1/120 inch control grid, so that the paper web 5 travels exactly 1/6 inch with respect to the ruler 65 with each step in the transport grid. Any slippage between the friction roller 106 and the paper web 5 is compensated for.
- the recording on the paper web 5 takes place precisely in a 1/6 inch grid with respect to the edge holes 21 or the marking (fold or transverse perforation) 22 which marks a start of the page on the paper web 5.
- the clock signals of the spiked wheel sensor 85 i.e. the actual feed of the paper web 5
- target feed positions which are derived from the clock signals 30 of the image generation unit.
- the drive controller 100 compares the image generation clocks 30, or selected clocks thereof, with the clocks 32 of the spiked wheel sensor 85 and forms drive clocks 31 for the stepping motor 102, which each correspond to a feed of 1/120 inches on the paper web 5. For example, if the pulses 30 of the exposure unit are supplied in a raster that corresponds to 1/9600 inch feed on the recording medium 5 and the spiked wheel sensor 85 generates a sensor pulse 32 with every 1/2 inch paper feed, the drive controller 100 checks in each case whether a pulse the sensor pulses 32 together with every 4800th exposure pulse 30 falls. If the sensor pulse 32 arrives with a time delay in relation to the exposure pulse 30, the drive control detects a slip and forms correspondingly more drive pulses 31 per unit of time.
- the drive clocks 31 are not in a fixed frequency relationship to the exposure clocks 30. This frequency decoupling of the drive clocks 31 from the exposure clocks 30 enables the drive control 100 to slip based on a time difference between the selected target signals 31 and the actual signals 32 in FIG. 1 Recognize the / 120-inch control grid and flexibly and precisely compensate for the 1/6 inch transport grid.
- the exposure unit comprises, for example, a light-emitting diode character generator (LED-ZG), as described in WO 96/27862 A.
- the clock signals 30 can be formed and / or tapped at a suitable point within the character generator described there.
- the content of this WO publication is hereby also incorporated by reference into the present description.
- the entire drive is aligned with the 1/6 inch transport grid or fitted into this grid.
- the controller generates 100 drive cycles in steps of 1/120 inch until the pinwheel sensor 85 or an edge hole of the paper web 5 is in a predetermined position (for example a pin in a vertical position). If the drive is aligned with the 1/6 inch transport grid, the paper web 5 can be moved in this transport grid in such a way that a reference point, for example a fold 22, is exactly one 1/6 inch step with each 1/6 inch transport step - Move the mark on the fixed ruler 65 to the next 1/6 inch step mark.
- the following pages are then automatically positioned exactly by the transport control.
- the drive control 100 controls the drive in the 1/6 inch transport grid.
- the slip compensation takes place within the regulation grid of 1/120 inch.
- the spiked wheel sensor 85 has a resolution which is equal to or lower than the transport grid width (1/6 inch), for example 1/6, 1/3 or inch. The closer the resolution of the pinwheel sensor 85 is to the hole spacing (1/2 inch) of the paper web 5, the more accurate is the information it provides about where a transport hole 21 is located. If, for example, the pinwheel sensor 85 resolves to the nearest inch, its signal indicates that a transport hole 21 is exactly in a previously known area of the pin currently in engagement. This automatically creates a defined relationship between the current scanned hole position and the ruler.
- the adjustment dependency of different pinwheel sensors can be compensated by a one-time reference measurement with determination of an offset value.
- the recognition of the clear assignability of the hole position is particularly advantageous in a quick start mode: while the paper web is being fitted into the transport grid, it can be automatically ensured that the edge holes 21 are in defined positions of the ruler 65.
- the above-described step, to be carried out by the operator, of positioning a specific mark of the paper web 5 on a marking 65a of the ruler 65 can, in favorable cases, if, e.g. the side length is irrelevant.
- the correct position of the beginning of the page relative to the edge holes 21, which may be necessary, for example, for post-processing of the printed paper web 5 in cutting devices, is then given in spite of the simplified starting operation.
- control grid is finer than the transport grid.
- the grids were specified in a reference system aimed at inches, but can of course also be transformed to other reference systems, for example to steps of the stepper motor or to the angle of rotation of corresponding drives or sensor axes.
- a comparison of the actual feed signals supplied by the pinwheel sensor 85 with the exposure cycles 30 provided by the image generation unit takes place within the drive controller 100 in order to be able to calculate correction values for controlling the stepping motor 102.
- the pinwheel sensor is only required if punched paper is used. For this purpose, it is mounted on, and can be swiveled out within the drive unit.
- other sensors can also be used to scan the edge punches, for example light barriers which detect the edge punches with reflected light or with transmitted light, or CCD line sensors. Such sensors can then be installed fixed to the device. This means that they do not have to be swiveled away when paper with no perforations is processed.
