Definitions
- the invention relates to a device, in particular a printer or copier, with two essentially identical electrographic printing units, each printing an image pattern on a sheet material, with an input section via which the sheet material can be fed individually one after the other, and with an output section via which the printed sheet material is output one after the other.
- Such electrophotographic printers are for example from DE 34 16 252 AI, EP 0 104 022 A2, DE-PS
- a sheet that is to be printed on both sides in duplex operation must then be accelerated several times in the opposite direction in order to be able to be printed on both sides by the one remaining printing unit.
- the device according to the invention two essentially identical printing units are used.
- the components for these printing units e.g. the electronic control, the developer units, the toner supply and discharge devices etc. can be kept almost unchanged.
- Each printing unit on its own therefore has a very high level of reliability.
- Both printing units use a common input section through which the sheet material is fed.
- both printing units jointly use an output section for removing the printed sheet material.
- the new device is very compact and can be manufactured with little effort. Due to the two printing units, the printing performance is significantly increased.
- a sheet-shaped material printed by one of the two printing units can be fed to the same printing unit again in the same direction as in the first printing process.
- a first transfer printing transport path is provided for the first printing unit and a separate second transfer printing transport path for the second printing unit.
- the transfer printing for both printing units takes place at the same speed. Since each printing unit has its own transfer printing transport path, sheet-like material can still be printed with the other printing unit if one printing unit fails.
- the two rings are connected via two three-way switches.
- the input section contains a switch which supplies sheet material either to the first transfer printing path or to the second transfer printing path.
- the operating mode simplex printing is realized with one color, ie supplied sheet material, for example single sheets of paper, are printed on one side by the first printing unit or by the second printing unit.
- the switch leads sheet material alternately to the first transfer printing path and the second transfer printing path. Since each printing unit prints the sheet material with the same transfer printing speed and two printing units are arranged in parallel, the printing capacity in the device doubles overall. Accordingly, single sheets can be fed in and out again at twice the printing speed.
- first transfer printing transport path and the second transfer printing transport path are connected by a connecting channel through which sheet material can be conveyed in one or in both transport directions.
- a connecting channel through which sheet material can be conveyed in one or in both transport directions.
- a further embodiment provides that the sheet-like material is turned during transport from the first transfer printing path to the second transfer printing path.
- each printing unit can print on the front and also on the back of a single sheet. If developer stations with different colors are used for the two printing units, two image patterns with two different colors can be printed on each side of the single sheet, ie so-called two-color duplex operation, also called duplex color spot operation, can be implemented.
- a printer system in which two similar, previously described devices are connected by a transfer device that supplies the sheet-like material printed by the first device to the second, similar device. If each of these two devices contains printing units of different colors, single sheets can be printed with four colors on both sides.
- a transfer device that supplies the sheet-like material printed by the first device to the second, similar device.
- a method for printing sheet material is specified according to claim 25.
- FIG. 1 schematically shows the structure of a high-performance printer in which the invention is implemented
- FIG. 2 shows schematically the operating mode simplex printing with the lower printing unit
- FIG. 3 schematically, the operating mode simplex printing with the upper printing unit
- FIG. 4 the operating mode alternating simplex printing
- FIG. 5 the duplex printing mode
- FIG. 6 shows the two-color silicon printing mode
- FIG. 7 shows schematically the operating mode two-color duplex printing
- FIG. 8 shows an arrangement with two high-performance printers which are connected to one another by a transfer device.
- FIG. 1 shows a high-performance printer 10 which is used for the rapid printing of single sheets of paper.
- the high-performance printer 10 contains a first, lower printing unit D1 and a second, upper printing unit D2. Both printing units Dl, D2 work according to the known electrographic process with the same transfer printing speed.
- the printing units D1, D2 are followed by fixing devices, which are indicated schematically in FIG. 1 by two pairs of rollers 12, 14.
- a paper input 16 is connected to the high-performance printer 10 and contains a plurality of storage containers 18 to 24 with single sheets as well as an external paper feed channel 26, via which single sheets can be fed from the outside. Single sheets are fed to an input section 28 via a transport channel.
- the high-performance printer 10 delivers the printed single sheets via the output section 42.
- Transport paths for the transport of the single sheets are arranged in the interior of the high-performance printer 10, through which various operating modes of the high-performance printer are realized.
- the printing units D1, D2 are each assigned U pressure transport paths 44, 46, which are each set by drives so that the single sheets fed to the printing units D1, D2 have their transfer printing speed. Both Transfer printing transport paths 44, 46 are connected to one another via a connecting channel 48.
- the transport path around the first printing unit D1 is supplemented to form a ring Rl by a feed channel 50, via which single sheets can also be fed from the input section 28 to the second transfer printing transport path 46.
- the transport path for the second printing unit D2 is supplemented in a similar manner to form a ring R2 by a discharge channel 52, via which individual sheets printed by the printing unit D1 can be fed to the output section 42.
- a first switch W1 is arranged between the input section 28, the first transfer printing path 44 and the feed channel 50, which enables single sheets to be fed from the input section 28 either to the first transfer printing path 44 or to the feed channel 50.
- a further variant is then that single sheets transported 50 m in the direction of the switch W1 can be fed to the first transfer printing path 44 on the feed channel.
- a second switch W2 and a third switch W3 are arranged at the ends of the connecting channel 48 and connect the adjacent transport paths 44, 48, 52 and 46, 48, 50, respectively.
- a fourth switch W4 is located near the output section 42 and connects the adjacent transport routes.
- the paper output 30 contains a fifth switch W5, which works as a turning device. Furthermore, it should also be pointed out to a control device 54, to which rejects are fed via a switch W6.
- FIGS. 2 to 7 Various arrangements of the high-performance printer 10 can be realized by the arrangement described in FIG.
- the various operating modes are shown schematically in the following FIGS. 2 to 7.
- the respective requirement of the single sheets is illustrated by arrows.
- the simplex printing is shown schematically with only one printing unit. With this simplex printing only one side of a single sheet is printed.
- the single sheet reaches the first transfer printing path 44 via the input section 28 and the appropriately switched switch W1 along the arrow P1 and is printed on the printing unit Dl.
- the single sheet is then output along the discharge channel 52 (arrow P2) via the output section 42 m of the paper output 30 (arrow P3).
- FIG 3 shows the simplex printing with the upper, second printing unit D2.
- the single sheet is transported via the feed channel 50 (arrow P4), the second transfer printing path (arrow P5) to the paper output 30 (arrow P6).
- FIG. 4 shows schematically the transport of the single sheets.
- the switch Wl alternately feeds the feed channel 50 or the first transfer printing path 44 single sheets (arrows P7, P8).
- the single sheets are slowed down to the transfer speed on their transport to the printing units D1, D2, printed there on the front side and then further requested to the switch W4.
- the single sheets are accelerated to at least twice the transfer printing speed, so that they are output at a distance from one another at the common output section via the switch W4 and are subsequently transported on the paper output 30 at least twice the transfer printing speed according to the arrow Pll can.
- the single sheets are also conveyed and deposited at at least twice the speed.
- the single sheets arrive at the common input section 28 and at the common output section 42 without a collision of single sheets and consequently a paper jam occurring.
- the transport paths for the single sheets fed to the first printing unit D1 and the single sheets fed to the second printing unit D2 are preferably designed symmetrically or at least the same length, so that the single sheets can be braked and accelerated on both transport paths with the same speed profile. This makes it possible to construct the drives and devices required for transport in the same way. It is also possible to use similar controls.
- FIG. 5 shows schematically the duplex printing mode, in which the single sheets are printed on both sides.
- the single sheets fed to the input section 28 are fed through the first switch W1 to the first transfer printing transport path 44 (arrow P13).
- the respective single sheet is conveyed a turning distance according to the arrow P14 beyond the switch W2.
- This turning path is part of the discharge channel 52.
- the conveying direction is then reversed according to arrow P15, and the switch W2 then guides the single sheet according to the arrow P16 into the connecting channel 48.
- the single sheet is then moved from the switch W3 in the direction of the arrow P17 diverted to the second transfer printing transport path 46.
- the printing unit D2 is therefore fed the back side of the single sheet which has not yet been printed for printing.
- the individual sheets are then fed to the switch W4 in accordance with the arrow P18 and transported to the paper output 30 along the arrow P19.
- the W5 switch serves this purpose.
- the single sheet is first predetermined by the switch W5 in the direction of arrow P20 Turning route led. Then the transport direction is reversed in accordance with arrow P21 and the switch W5 requests the single sheet in the direction of arrow P22, whereupon it is deposited in the storage compartments 32 to 36 in the correct direction.
- the switch W2 works as a turning device to feed the back of the single sheet to the printing unit D2.
- the turnout W3 can also be used.
- the Emzel sheet leaving the printing unit D1 is then guided over the switch W2, the connecting channel 48 of the switch W3 and then for a short turning distance along the feed channel 50 m in the direction of the switch Wl.
- the transport direction is then reversed and the switch W3 guides the single sheet in the direction of the printing unit D2 with its rear side upwards.
- FIG. 6 schematically shows a further operating mode, two-color simplex printing, in which the front of an individual sheet is printed with two image patterns of different colors.
- the two printing units D1, D2 print image samples of different colors.
- the single sheet is fed to the printing unit Dl via the switch Wl (arrow P25).
- the single sheet is then fed via the switch W2 to the connection channel 48 without turning and then via the switch W3 to the printing unit D2
- the printing unit D2 prints the front side with a different color from the printing unit Dl
- Emzelblatt is then output via the switch W4 to the paper output 30 (arrow P28).
- FIG. 7 schematically shows the transport path of a single sheet in the two-color duplex printing mode, in which the front and the back of an individual sheet are printed with image patterns of different colors.
- the prerequisite for this is that the printing units D1 and D2 print different-colored print images.
- the arrows P25, P26, P27 and P28 illustrate the transport route.
- the single sheet is then fed again to the printing unit Dl.
- the arrows P29 to P36 illustrate the transport path of the single sheet for printing on the back. So that this back side is fed to the printing unit Dl, the single sheet must be turned on the transport path between the printing unit D2 and the printing unit Dl.
- This turning can take place, for example, on the switch W4, the switch W2 or the switch W3.
- the turning is carried out with the turnout W4, ie the single sheet is first transported for a short turning distance in the direction of the turnout W5, then the transport direction is reversed and the single sheet in the direction of the turnout W2 is further requested.
- the turnout W5 After being transported into the paper output 30 according to the arrow P36, the turnout W5 further turns and then the correct positioning of the single sheet printed on both sides with two color images.
- An alternative transport of the single sheet through the high-performance printer 10 to implement the two-color duplex printing mode can be carried out in the following manner.
- the Emzel sheet is fed from the input section 28 via the switch W1 to the printing unit Dl, its front side is printed and then passed briefly in the direction of the switch W1 via the switches W2 and W3 for turning.
- the transport direction m is changed in the direction of the printing unit D2 and the Emzel sheet is requested on the transfer printing transport path 46.
- the switch W3 thus serves as a turning station.
- the back of the single sheet is accordingly printed on the printing unit D2.
- the Emzelblatt is again fed via the switches W4, W2, W3 and Wl to the first printing unit Dl in order to now print on the back.
- the Emzelblatt must be turned over for this. This is done at switch W4, where it is briefly requested in the direction of switch W5, the transport direction is reversed and transported in the direction of switch W2 in the turned state.
- the single sheet After printing on the back of the single sheet in the printing unit D1, the single sheet is fed to the printing unit D2 via the switches W2 and W3, whereby it is turned. Now the front is printed by the printing unit D2.
- the single sheet is then fed over the switch W4 to the storage compartments 32 to 36. Since it now arrives in the correct position, that is to say with the top side upward in the deposit 30, it does not have to be turned again through the switch W5.
- FIG. 8 shows the arrangement of two high-performance printers 10 and 10 'to form a printing system 55.
- the two high-performance printers 10 and 10' are constructed in the same way, and the individual components therefore do not have to be explained again.
- a transfer device 56 is arranged which conveys single sheets from the high-performance printer 10 to the high-performance printer 10'.
- Each high-performance printer 10, 10 ' can implement the operating modes simplex printing, alternative simplex printing, two-color simplex printing, single-color duplex printing and two-color duplex printing.
- both high-performance printers can operate in two-color simplex mode, the first printer printing the front with two different-colored image patterns and the high-performance printer 10 'printing the back with two different-colored image patterns.
- four-color duplex operation can be implemented by the printing system 55, ie the front and the back can be printed with four different-colored image patterns.
- the printing system 55 can be expanded further by connecting at least one further high-performance printer in the manner of the high-performance printer 10 to the high-performance printer 10 '. In this way, using all technical possibilities of the high-performance printers, an n-color duplex printing can be made possible, in which an n image pattern with n different colors is printed on the front and back of a single sheet, where n is any integer.
