Definitions

  • the invention relates to a device according to the preamble of claim 1 and to a method for the discontinuous feeding of recording media to the platen of an office machine.
  • the record carriers can be single sheets or envelopes, for example, and are simply referred to below as sheets for simplification.
  • a device of the type mentioned in the preamble of claim 1 is known from DE-AS 28 57 074.
  • the separating device is coupled to the platen roller in such a way that it is driven via an overrunning freewheel only when the platen roller is rotated against the paper feed direction, ie backwards.
  • Such a function means that the sheet that is fed cannot be drawn in by the platen during the feeding process, so that it is stopped at the platen of the platen and bulged out by the feed of the separating device. Only when the platen roller is reversed in the forward direction is the sheet transported by the platen roller Functionally, the aim is to ensure that the sheet assumes a precisely defined starting position for precise line positioning prior to reversing the platen roller.
  • the sheet cannot be held in lateral guides up to the actual nip point or nip line of the rollers forming the nip, which is particularly important in the case of thin sheets.
  • the shear force exerted by the separating device on the trailing sheet section can, due to the lack of sufficient bending stiffness, result in the sheet bending and evading even with low friction acting on the leading sheet section.
  • leading edges of the sheets are slightly wavy, or if they were bent by the separating device when they were removed from the paper supply magazine, or if they were even kinked slightly, they prevent the correct insertion into the feed gap and the bulging of the sheets that have come to a standstill due to the separating roll cannot be guaranteed. that the leading edges still reach the predetermined position.
  • the invention has for its object to ensure the correct and always consistent positioning of the sheets to be fed by the office machine in the feed nip of the rollers feeding the sheets into the office machine to guide each sheet as it is fed into the entry nip, and to ensure that the feed process for this sheet always starts when the rollers responsible for the feeding process start the feeding movement.
  • a guiding of the sheet at its leading section in the area of the feed gap is achieved in that the rollers move in the feed direction at least during this part of the feed path and thereby also feed the leading sheet edge to the feed gap when the feed path is tangent to the rollers at the clamping point is not given or the leaves have irregularities on their leading edges. While this fulfills a first requirement for the correct positioning of the leading edge of each sheet in the feed gap, a further essential element of the invention lies in the fact that the actual positioning or position determination of the leading edge is not accomplished by shear forces from a trailing sheet section, but by those which directly attack a short section of the sheet comprising the leading edge. As a result, sheet thickness has virtually no impact on the ability to ensure accurate positioning of the leading edge.
  • This positioning also occurs automatically since the backward rotation of the rollers forming the feed nip on the sheet or its leading section is only effective as long as it is in the clamping area of the rollers. As soon as the sheet has left the clamping area, its leading section also comes to a standstill. The position in which the blade comes to a standstill is always the same.
  • Feeding the sheet with its leading sheet edge as it is fed, i.e. before positioning the same, has the advantageous side effect that the rollers have a smoothing effect on this sheet edge.
  • the leading sheet edge has passed twice through the clamping area of the rollers. It can therefore be expected that this sheet edge is straightened and will no longer cause positioning errors.
  • the sheet under tension can be expedient to bring the sheet under tension during the pushing back, for example by braking it on a subsequent sheet section. In certain cases, this can further improve the security of line-by-line entry into the office machine. In addition, even slight skewing of the sheet that resulted during feeding can be corrected with greater certainty by this measure. Since the applied tension is effective over the entire sheet width, if at all to a different extent, the leading sheet edge is in any case placed in a position parallel to the platen roller and the feed takes place simultaneously over the entire sheet width. The pulling in of the sheet from its leading edge then has the consequence that the subsequent sheet sections are also aligned.
  • the reverse rotation of the rollers forming the feed nip one of which is usually the platen of the office machine and is in drive connection with the separating device of the supply magazine for the sheets to be fed, ge allows you to control this drive connection.
  • the paper feed can thus be interrupted by the separating device during the roller movement necessary for positioning the sheet without additional control movements and can only be started again when there is a need for a new sheet on the office machine.
  • the invention can also be applied in particular to office machines, in which a plurality of storage magazines must be provided for possibly different sheets, each of which can be called up selectively, it is important for the device that the coupling device, which in this case is one of the number of stock magazines corresponding number must be available, can be equipped very easily and inexpensively.
  • the coupling device in particular according to claim 2, can be designed very inexpensively, in that the engagement means and the ratchet wheel serve on the one hand to establish the drive connection and on the other hand do not impede the pulling out of the sheet from the separating device by a faster-running platen roller, so that the need for one No overrunning freewheel.
  • the ratchet lever in connection with the driver serves on the one hand to engage and disengage the coupling device and on the other hand as an engagement means for the ratchet wheel.
  • Claim 4 specifies a preferred embodiment for the storage of the ratchet lever.
  • the coupling means of the ratchet lever can be formed, for example, by a recess in which the driver engages.
  • the driver is used not only to take away, but also to operate the latch lever.
  • a preferred embodiment according to claim 8 ensures that the sheet maintains a pre-tension on the feed nip when it is temporarily ejected from the nip of the platen roller. It is possible that it is either still in engagement with the separating device or, if it has already left the separating device shortly before, is prevented from being pushed back by the guide elements, for example a curved guide channel or a spring acting on the sheet, in the stretched-out state.
  • the disengaging device from the separating device is possible in the case of record carriers which are short in the conveying direction, for example in the case of envelopes.
  • a method for operating the device is specified, from which it emerges how the platen is to be operated to achieve the desired functions.
  • the actuation is carried out by the program-controlled drive of the platen roller.
  • FIG. 1 shows a device 1 for feeding sheets 3 stacked in a magazine 2 to the platen roller 4 of an office machine (not shown).
  • the platen roller 4 which can be driven by a drive 5 by means of transmission members 5 ', limits, together with a first pressure roller 6, a feed nip 7 for the respectively fed sheet 3', which feed nip 7 ends in a clamping area 7 'formed by the platen roller 4 and the first pressure roller 6.
  • the nip area is the finite area that includes the theoretical nip line and within which the distance between the roller surfaces is smaller than the sheet thickness.
  • a platen 8 and a second pressure roller 8 ' are assigned to the platen roller 4 in a known manner.
  • the feed device 1 has guide plates 9 and 9 'for guiding the sheet 3' in the direction of the feed gap 7.
  • the feed device 1 is plugged onto the office machine in a known manner and is coupled in terms of drive via a gearwheel 42 to the platen roller 4, by which it is driven when the platen roller 4 is rotated.
  • the gear 42 meshes with a drive wheel 44 of a coupling device 10, via which at least one separating roller 11 of a separating device can be driven.
  • the separating roller 11 pulls the top sheet 3 'from the stack and feeds it between the guide plates 9 and 9' to the feed nip 7.
  • the coupling device 10 can be engaged and disengaged by rotating the platen roller 4 in reverse.
  • the coupling device 10 is arranged on a shaft 12 of the separating device shown in cross section (FIG. 1), which has the separating roller connected to the shaft 12 in a rotationally fixed manner.
  • a ratchet wheel 14 is rotatably connected to the shaft 12.
  • a drive plate 16 is freely rotatably mounted on the shaft 12, in which a pin 18 is arranged, about which a ratchet lever 20 is pivotally mounted.
  • the pawl lever 2o has a pin 22 which extends through a slot 24 arranged in the drive plate 16 to the other side of the drive plate 16.
  • a tension spring 26 engages the pin 22 in order to keep the pawl lever 20 with its pawl 28 out of engagement with the ratchet wheel 14.
  • the tension spring 26 is attached to the drive plate 16 by means of a pin 30 braced.
  • the slot 24, at one end of which the pin 22 rests, determines the rest position of the ratchet lever 20.
  • the driving disk 16 is freely rotatably mounted on the shaft 12.
  • the shaft 12 in turn is mounted in a bearing 32 of a housing part 34 and is secured against axial displacement to the right by a locking washer 36 bearing against the bearing 32.
  • a saddle plate 38 is arranged on the shaft 12, which serves as a friction brake for the drive plate 16, so that it is not entrained by the rotation of the shaft 12.
  • the ratchet wheel 14 is rotatably connected to the shaft 12.
  • the gearwheel 42 is mounted on a fixed shaft 40 connected to the housing part 34. This gear wheel serves as a gear element for coupling with the platen roller 4 according to FIG. 1 or directly with its drive 5.
  • the gear wheel 42 meshes with the drive wheel 44 which is freely rotatably mounted on the shaft 12 of the separating device.
  • the drive wheel 44 is on the shaft 12 Locking washers 46 and 48 secured against axial displacement.
  • a drive 52 is pivotably mounted on the drive wheel 44 on a pin 50.
  • the driver 52 is held in a predetermined position by means of a spring 56 braced on a further pin 54 inserted into the drive wheel 44.
  • FIG. 2 does not represent a sectional view according to FIG. 3, but only serves to schematically illustrate the relative position of the driver 52, the ratchet lever 20 and the ratchet wheel 14 relative to one another.
  • the pawl lever 20 is mounted on the drive plate 16 shown in FIG. 2, while the driver 20 is mounted on the drive wheel 44, not shown in FIG.
  • the driver 52 has an angled arm 58 which is held in a rest position by the spring 56. At its end, the arm 58 carries a driver lug 60 which extends into the plane of the ratchet lever 20. With the exception of the driver lug 60, the ratchet lever 20 and the driver 52 are arranged in different planes in such a way that they do not touch when they are mutually covered. In Figure 2, the axial position of the driver arm 58 with its driver nose 60 relative to the ratchet lever 20 is shown in dashed lines.
  • the gearwheel 42 (FIG. 2) establishes such a rotary connection with the platen roller, not shown, that the direction of rotation shown in FIG. 2 at 62 results when the platen roller rotates forward.
  • a driver stop 64 is arranged on driver plate 16, which interacts with driver nose 60.
  • the driver stop 64 serves to produce a predetermined relative position between the driver 52 and the ratchet lever 20.
  • the driver stop 64 has inclined surfaces 64 'and 64 ", which serve to force the driver nose 60 into its central position, if the force of the spring 56 is not sufficient due to the increased friction of the driver 52 on the pin 50.
  • the pawl lever 120 has, as an engagement means, a recess 66 which is directed opposite the forward direction of rotation 62 and which is intended for engaging the driver nose 60 of the driver 52.
  • the drive wheel 44 of the coupling device 10 rotates in the direction of the arrow 62, with the driver 52 pulling the driver disk 16 over the driver stop 64.
  • the pawl lever 20 is in its rest position shown in FIG. 2, so that no drive connection is made with the shaft 12 of the separating device. If a new sheet is now to be fed from the magazine through the separating device to the platen roller, then the platen roller is rotated backwards by an angle which corresponds to an angle 68 on the coupling device 10. With such a reverse rotation, the drive wheel 44 with the driver 52 located thereon is also turned back.
  • the drive plate 16 stops due to the effect of the saddle plate 38 which inhibits its rotary movement.
  • the driving arm 58 of the driving 52 is displaced radially outward against the force of the spring 56 when its driving lug 60 runs onto the outer flank 76 of the ratchet lever 20.
  • the driving lug 60 snaps in the direction of the off Saving 66 of the ratchet lever 20.
  • the driver nose 60 of the driver 52 engages in the recess 66 of the ratchet lever 20 after an angle of rotation 70 ′.
  • the catch 52 causes the pawl lever 20 to pivot about its bearing journal 18 in a clockwise direction until the pawl 28 of the pawl lever 20 engages in the toothing 14 'of the ratchet wheel 14 and takes it along in the direction of the arrow 62.
  • the drive connection from the platen to the separating device is made in the forward rotation 62.
  • the sheet to be fed is drawn off the stack by the separating device and fed to the feed nip of the platen roller.
  • the platen roller is rotated until the front edge of the sheet is caught by the platen nip.
  • the sheet is then typically drawn in by approximately two line steps of the platen roller.
  • the platen roller is rotated back by an angle which corresponds to the angle 72 on the coupling device 10.
  • the driving lug 60 releases the ratchet lever 20, the ratchet 28 of which rises from the ratchet wheel 14, since the spring 26 returns it to the rest position shown in FIG. 1.
  • the driver nose reaches the dashed position 60 ', since the driver 52 assumes its central position again under the action of the spring 56.
  • the driving lug 60 slides on an inside deflecting surface 78 of the pawl lever 20 over the pawl 28 until it rests against the driving stop 64 and thereby rotates the driving disk 16 again empty.
  • the following forward rotation of the platen roller takes place step by step to write on the sheet fed.
  • FIG. 4 schematically shows the movement of the platen roller and thus that of the driver 52 in a linear form.
  • the ending forward rotation 62 was used to remove the previously labeled sheet.
  • the driver arrangement 52, 20, 14 is latched in and by the subsequent forward rotation 70 'the driver nose 60 engages in the notch 66 and, with further rotation in the same direction, the ratchet wheel 14 is carried along for separating and feeding the next sheet.
  • the angle of rotation of the forward rotation 70 is dimensioned such that the fed sheet 3 'is grasped by the clamping area 7' of the platen roller 4 at its front edge.
  • the subsequent reversal in the reverse direction of rotation 72 serves on the one hand to disengage the driving lug 60 from the ratchet lever 20 and on the other hand to repel the sheet 3 'supplied from the clamping area 7' of the platen roller.
  • the pushing back ends when the previously detected sheet 3 'is pushed with its front edge out of the clamping area 7' of the rollers 4, 6 and is directed exactly parallel to the platen roller 4.
  • the sheet 3 ' is also positioned exactly in the nip 7 of the platen roller.
  • the sheet will in any case adhere to it in the feed gap 7 lying leading section are under a bending stress which counteracts the frictional force exerted by the rollers 4, 6 on the leading sheet edge or leading edge.
  • the sheet is actively fed to the nip area 7 'of the rollers during a subsequent forward rotation 74 of the platen roller and drawn in line by line.
  • the reverse rotation 72 also ensures that the required tension of the sheet is present directly at the feed gap 7. If the tension were applied to the other end of the sheet, it would not be ensured that the sheet or its leading edge would be in contact with the rollers in the feed nip with sufficient force.
  • the separating roller 11 pressing against the stack can serve as a return inhibitor for the sheet if the sheet length is sufficient to be still in engagement with the separating roller and the platen roller.
  • the guide channel 9-9 'of the sheet can serve as a backflow inhibitor, since a slight resistance is sufficient to put the sheet under bending tension in front of the feed nip 7 of the platen roller 4.
  • baffles such as leaf springs or bristles, can be arranged in the conveying path of the sheet to the platen roller.
  • each reverse rotation of the platen causes the gear 42 and the drive wheel 44, which carries the driver 52, to be rotated (FIG. 3).
  • the drive plate 16 carrying the ratchet lever 20 has an approximately screw-like deflection curve, generally designated 140, for the drive nose 60 of the drive 52.
  • this curve 140 extends over a little more than 360 °. Since the extension of the curve affects the possible way to work when "plotting", i.e. determines the length of the sheet section that can be used for this purpose, it may be expedient to allow the curve to extend in a helical manner over several round trips, for example 1080 °. It is also possible to design the extension of the screw exactly in accordance with the possible working length with a predetermined blade length.
  • the curve 140 has run-up surface parts 142 and 144 which face each other and delimit a narrowing path 146.
  • a driver stop is formed by the surfaces 148 and 150, which corresponds to the driver stop 64 of the exemplary embodiment according to FIG. 2 in terms of function and general shape.
  • the driver nose runs out on the curve 140 and can cover a path along this, corresponding to a full revolution.
  • the corresponding recording process can begin and, if necessary, can proceed without further reversal of the direction of rotation until the driving lug has again come into the vicinity of the run-up surface 142.
  • the driving lug 60 is moved past the inner deflecting surface 78 of the ratchet lever 20 into the starting position at the driving stop 148, 150 during the subsequent forward rotation of the drive wheel 44. This restores the readiness to initiate a new sheet feed.
  • Program control devices which are generally known and which therefore do not need to be dealt with here are used to carry out the required rotary movement of the platen roller.
  • the feed device according to the invention is adapted to these conditions can be engaged and disengaged by rotating the platen roller backwards.
  • Such an embodiment is not tied to the exemplary embodiment shown, but can be designed as desired by the person skilled in the art in order to achieve the same conditions.
