Definitions

  • the present invention relates to a single-sheet feeding device for a printer-side slot-type printer according to claim 1 and a printer device according to claim 6.
  • a cut sheet feeder for a copier or printer, particularly a laser printer is known from CH-A-678169.
  • the feeder comprises three magazines located below the printer, each of which is arranged to receive a stack of sheets.
  • the stack receiving part of each of the magazines can be pulled out for refilling as a drawer.
  • each of the magazines has a separating device and upwardly directed conveying rollers. The promotion of leaves from a magazine lying below an upper magazine is done by the overlying magazines.
  • One of the magazines is equipped with a motor which drives all magazines.
  • the single-sheet feeding device has a base module forming a base, in which a base Drive motor is arranged. This is in operative connection with a magazine arranged on the base module in order to drive at least its conveying means for a vertical sheet transport. Since the drive motor is arranged in the base module, said magazine and none of the other magazines require a drive motor. Next is space for a powerful engine available, which is able to drive a number of magazines.
  • the single-sheet feeding device further offers the possibility of a base unit in the power supply, a logic electronics for the control of the magazine and an interface electronics for communication between a arranged on the respective top magazine printer and the magazine or magazines accommodate.
  • the single-sheet feeding device further makes it possible to use standard supplementary magazines of the printer as magazines, with only slight adjustments being necessary at most.
  • the figure shows a single-sheet feeding device 10 with a base module 12, on which three magazines formed as individual units 14 are arranged horizontally one above the other, and a printer 16 with an additional magazine 18, which is on the top of the magazines 14.
  • the cut-sheet feeder 10 together with the printer 16 form a tower-like printer device 20 which receives print jobs in a known manner, for example from a computer.
  • the base module 12 has a substantially rectangular bottomless base box 22, for example made of sheet metal, at the corners of each a driving roller 24 is mounted.
  • An upper portion of the side walls 26 of the base box 22 is formed in a truncated pyramid, on the one hand to give stability to the base box 22 and on the other hand to obtain as large as possible defined by the driving rollers 24 footprint.
  • Kippschutzbeine are wegrisebar fixed by screws in the corners of the truncated pyramidal part.
  • the free ends of the Kippschutzbeine 28 are located a few millimeters above the defined by the rollers 24 footprint.
  • the top wall of the base box 22 forms a base for the bottom of the magazines 14, which may be attached by means of screws to the base box 22, for example.
  • a power supply 30 is attached to the ceiling wall, which serves to feed the cut sheet feeder 10.
  • a logic electronics 32 and an interface electronics 34 which serve on the one hand, the control of the cut sheet feeder 10 and on the other hand, the communication between the printer 16 and the cut sheet feeder 10.
  • an electric drive motor 36 with a gear 38 which, for example, designed as a gear driven output member 40 drives. This protrudes through a recess in the top wall of the base box 22.
  • the three magazines 14 are formed as independent units and as a box 52 which has a drawer 44 with a slot for receiving a sheet stack 46 in a known manner.
  • each box 52 there is a separating device 48 which, in a known manner, drives a single sheet 46 'from the sheet stack 46 when the relevant magazine 14 is actuated, which by means of deflecting elements 50 into a vertical conveying path 52, which by means of a dotted line is indicated, is diverted.
  • the vertical conveying path 52 leads from the interior of the lowermost magazine 14, in the vertical direction upward, through the two magazines 14 and the additional magazine 18 arranged thereabove to a drawer-like printer magazine 56 integrated in a printer module 54 likewise a sheet stack 46.
  • the vertical conveying path 52 thus coincides in the additional magazine 18 with the conveying path of the individual sheets 46 'from the additional magazine 18 into the printer module 54.
  • the boxes 42 of the magazines 14 have on the bottom side a feed slot 58 and on the ceiling side a discharge slot 60 for the passage of the individual sheets 46 '.
  • a corresponding feed slot 58 and discharge slot 60 or a bottom-side feed slot 58 also have the additional magazine 18 and the printer module 54 in the region of the printer magazine 56. Through these feed and discharge slots 58, 60 passes through the vertical conveying path 52nd
  • these conveying means 64 of all magazines 14 are driven by means of the drive motor 36 in the base module 12.
  • the conveyor 64 may be formed differently in a known manner.
  • Each of the magazines 14 has drive transmission means which are designated 66 and serve to transmit the drive force from the driven element 36 driven by the drive motor 36 into all the magazines 14.
  • the drive transmission means 66 are shown purely schematically by a number of circles, which may, for example, represent mutually meshing tooth edges.
  • the lowermost magazine 14 has a drive element 68 embodied as a gear wheel which, when the magazine 14 is placed on the base module 12, also has the same formed as a gear driven element 40 meshes.
  • the drive transmission means 66 of the lowermost magazine 14 further comprise a likewise designed as a gear driven element 40 ', which is connected via intermediate wheels with the drive element 68 and projects through an opening in the top wall of the box 42 on this, in the same manner as the output element 40 with respect to the ceiling wall of the base module 12.
  • the drive transmission means 66 of the central magazine 14 are formed exactly the same as those of the lowermost magazine 14.
  • the drive transmission means 66 of the uppermost magazine 14 are the same as those of the other magazines 14 except that they have no output element 40 '.
  • the drive chain from the drive motor 36 in the base module 12 forth is thus interrupted between the uppermost magazine 14 and the printer 16 and its additional magazine 18.
  • the drive transmission means 66 are shown purely as intermeshing gears, for example. However, any other power transmission means is also conceivable.
  • the separating device 48 of each magazine 14 is driven by the logic electronics 32 ago and has a own drive, for example in the form of a small engine. However, it is also possible to remove the driving force for the separating device 48 from the relevant drive transmission means 66, wherein a clutch controlled by the logic electronics 32 is to be provided in order to drive the separating device 48 for the removal of a single sheet 46 'at the desired moment.
  • the printer module 54 has a printer drive motor 72 which, via a drive connection 74, drives the conveyor roller pair assigned to the printer magazine 56 in accordance with the conveyor roller pairs 62 of the magazines, on the one hand the individual sheets 46 'removed from the printer magazine 56 for printing along the vertical conveyor path 52 to promote upward and on the other hand along the vertical conveying path 52 from below incoming single sheets 46 'also in the same manner for printing introduce.
  • a printer drive motor 72 which, via a drive connection 74, drives the conveyor roller pair assigned to the printer magazine 56 in accordance with the conveyor roller pairs 62 of the magazines, on the one hand the individual sheets 46 'removed from the printer magazine 56 for printing along the vertical conveyor path 52 to promote upward and on the other hand along the vertical conveying path 52 from below incoming single sheets 46 'also in the same manner for printing introduce.
  • additional magazine 18 is formed exactly the same as the bottom and the magazine arranged thereon 14 with corresponding drive transmission means 66.
  • the output element 44 'corresponding element 40 is a drive element which with its attached printer module 54 with the drive connection 74th
  • the additional magazine 18, which otherwise has the same shape as the magazines 14, is thus driven by the printer module 54.
  • the drive connection is thus interrupted between the uppermost of the magazines 14 and the printer 16.
  • the printer device 10 receives a print job and the single sheet 46 'is the printer magazine 56 or To remove additional magazine 18, the cut sheet feeder 10 is not activated and the single sheet 46 'is fed to the printer module 54 in a known manner for printing.
  • the drive motor 36 is energized via the logic electronics 32, whereby the conveyors 64 of all the magazines 14 are activated, and on the other hand the singulation device 48 of the desired magazine 14 is initialized. This removes the desired individual sheet 46 'from the sheet stack 46 in question and feeds it to the vertical conveying path 52, along which it is fed to the printer module 54 by means of the conveying means 64 - the conveying roller pairs 62.
  • three magazines 14 are provided. It is of course also conceivable that only a single magazine 14 is present; in this case, it is the same as the uppermost one of the magazines 14 shown in the figure. If the printer device 20 has two magazines 14, these two are the same as the lowermost and uppermost magazines 14 of the single-sheet feeding device shown in the figure 10. However, it is also possible to provide more than three magazines 14, again all magazines 14 are the same, with the exception that the uppermost magazine 14 has no output element 40.
  • the magazines 14 may also be designed differently with respect to the embodiment shown and described. For example, this is a possible form of training in detail and described in CH-A-678169. In connection with the present invention, only such known magazines without drive motor are then used.
  • the printer 16 does not need to be equipped with an auxiliary magazine 18.
  • the printing module 54 stands directly on the uppermost of the magazines 14 and its bottom-side feed slot 58 is aligned with the cover-side discharge slot 60 of the uppermost magazine 14.
  • the printer 16 has neither an additional magazine 18 nor a printer magazine 56. In this case, all individual sheets 46 'are supplied to the printer 16 by means of the single-sheet feeding device 10.
