Definitions
- Electrographic printing device from at least one printing unit with a plurality of developer stations
- the filling of consumables from a container in a receiving means is particularly important in electrographic printing devices.
- the function of such a printing device is e.g. from WO 00/19278 known.
- WO 00/19278 known.
- WO 00/19278 is also described the addition of toner in the developer stations, to WO 00/19278 is therefore expressly noted and their contents are taken in addition to the disclosure. It is described how a container of toner can be connected to a developer station for new ones
- the toner transport connection between the developer station and the toner container is produced by a toner conveying channel, on which an electrical coding line is fixed, via which there is an electrical connection between the toner container and the developer station.
- This coding line can be used to ensure that the toner delivery channel is connected to the associated developer station and the correct toner container.
- the problem to be solved by the invention is, in the case of an electrographic printing device, which also has several printing units, each with a plurality of developer stations. NEN to have to ensure the toner supply from multiple toner reservoirs.
- the electrographic printing device has at least one printing unit, which contains at least one developer station, by means of which toner charge images are formed on an intermediate carrier.
- at least one arranged outside the printing unit toner reservoir is provided, which is connected by a toner transport channel with the developer station.
- the invention is based on the recognition that electrogravitic pressure devices are generally of modular design, with individual modules being able to be designed as aggregates which form a mechanical, electrical and / or control-technical unit.
- a printing unit can be such a module or aggregate and arranged outside the printing unit toner reservoir can be provided according to an advantageous embodiment of the invention in particular mechanically independent of the printing unit and continue to be set up independently of him within or outside the printing device and / or supported , In particular, it can be arranged in a spatial distance from the printing unit or even by the printing device that is significantly greater than the dimensions of the printing unit and / or can be mechanically connected to the printing unit only via the toner transport channel.
- the invention is particularly advantageous when a plurality of printing units each having a plurality of Wicklerstationen are provided.
- the toner supplementation can then take place by toner reservoirs arranged outside the printing units, which are each connected via a toner transport channel to a developer station or a plurality of developer stations, which can be assigned to one or more printing units.
- toner reservoirs can also be arranged outside the printing device.
- the developer stations of the printing units can also be designed such that they can also be supplied with toner manually, e.g. by manually filling a toner storage integrated in the developer station.
- the single toner transport channel can be designed as a suction channel through which toner can be sucked into the connected developer station.
- the toner reservoirs arranged outside the printing units are mounted in a toner transport unit, so that they are easily movable.
- the toner transport units can each be assigned a second circuit with a memory in which at least the ink filled in the associated toner reservoir is stored.
- a third circuit with a memory in which at least the filled color is stored.
- the toner transport channels can be assigned electrical connection lines (ping lines). These can be wrapped around the associated toner transport channels. However, the connection lines (ping lines) can also only be used to query which developer station is connected to which toner transport unit and the toner reservoir arranged therein.
- a main control module can be provided, which controls the processes in the printing units and in particular queries the colors contained in the developer stations and toner storage containers. Since the color is also stored in the toner transport unit, this can also be queried.
- the main control module for monitoring the developer stations is connected via a bus to the third circuit of the respective developer stations of the printing units.
- a sub-control module may be provided which is connected via a bus to the first and second circuits and to the main control module which detects and transmits at least the colors stored in the circuits of the toner transport units and tocorrelation containers to the main control module.
- the master control module can recognize which toner supply container is connected to which developer station. When this connection is polled through the ping line, the result of the polling is passed to the main control module. The main control module then determines if the connections are correct and compares the toner colors of the developer stations and the toner reservoirs; the toner color information is sent to the main control module via the bus.
- the main control module can detect the expansion state of the printing units and toner reservoirs with all possible combinations of connections of toner storage containers with developer stations. Then, the main control module can display the expansion state on a control panel to the operator.
- the main control module can use the color information stored in the circuits of the developer stations and toner supply containers or toner transport units to determine whether the respective developer station is connected to a toner supply container which contains the correct color. It is then advantageous for the toner transport unit to register its color when a toner reservoir is inserted and to communicate this to the sub-control module, which forwards this information to the main control module. For information to the operator, the main control module may display a color change on the control panel. This is convenient because the operator can take corrective action if an unwanted color change has occurred.
- the operator through the main control module via the control panel veran- let one first change or clean the components of the toner transport channel contacted with the previously used ink, in order subsequently to be prompted to have the new ink stored in the second circuit of the toner transport unit.
- the main control module thus generates an error signal when, during a color change within a toner transport unit or a different color toner reservoir, the components of the toner transport channel between the toner reservoir and developer station over which the preceding ink has been transported have not been replaced or cleaned. This prevents the toner of other color from being contaminated by the ink residues in these components. In this case, it is particularly important to clean or replace the toner transport channel.
- the error message indicates that the color of the toner stored in the toner transport unit deviates from the color contained in the toner supply container. Then it is assumed that the color change was unintentional or imperfectly completed. If the toner transport channels are also provided with an electrical circuit with memory, the color information can be stored there and can be determined by questioning whether the toner transport channel has been cleaned or replaced during a color change.
- the power supply of the circuits in the toner transport units is expediently carried out via the bus, which connects the toner transport units to the main control module.
- the first circuits insofar as they are implemented as transponders, do not require their own power supply, since the second circuit communicates with the transponder. For example, when the printing device is turned on, it is convenient to check the components that are important in the development of the toner images. In a first step, the developer stations can then be checked
- the toner transport units can then be checked,
- the functionality of the toner transport units can be checked to see if
- the toner transport channel is operatively connected.
- the connection between the toner transport unit and the respective developer station can be interrogated via the respective connection line and thereby checked.
- the main control module records the configuration of developer stations, toner transport units and toner reservoirs, and notes the current situation of the toner supply. To inform the operator, the current configuration can be displayed on the control panel.
- the main control module checks to see if the toners in the associated developer stations, toner reservoirs, toner transport units match, first performing a review of the developer station and the toner transport unit and then the toner transport unit and the toner reservoir. It is expedient if the main control module inhibits the printing operation if the toner dyeing of the associated developer station, toner transport unit or toner reservoir does not match. Furthermore, the main control module should query the respective developer station and its circuit as to how its toner supply (manually, by negative pressure) is executed and adjust the toner supply to the developer station depending on the result. Likewise, when changing the toner supply of the respective developer station, the information stored in its third circuit should be set by the main control module accordingly. The manual adjustment can be made by an operator.
- toner reservoirs are provided, which are connected by a toner transport channel with the developer stations.
- a supply manager controlled toner transport device is provided which transports toner from the toner supply containers to the developer stations.
- the developer stations provide toner requests to the supply manager who coordinates them and then allocates the supply permits to the developer stations in cycles.
- the clocks can have the same duration.
- a suction device can be provided for this purpose as a toner transport device, which transports toner from the toner supply containers into the developer stations by negative pressure and which is controlled by a suction cycle manager as a supply manager.
- the developer stations provide suction requests as toner requests to the suction cycle manager;
- the Suction Clock Manager coordinates the suction requirements of the developer stations and assigns the Sampling Permits to the developer stations in suction cycles that may be time-limited.
- the suction cycle manager can be integrated in a main control unit of the printing device as a control software.
- the suction cycle manager distributes the suction cycles allocated to the developer stations to the developer stations in such a way that a single suction device suffices for supplying the developer stations of the printing units.
- the suction cycle manager can allocate the suction cycle to only one developer station at the same time. With multiple printing units, the suction cycle manager can simultaneously allocate the suction cycle to only one developer station per printing unit.
- the suction cycle manager only allocates the suction cycle to a developer station which does not simultaneously use toner, e.g. promotes the development of charge images (delivery cycle). However, the suction cycle manager does not notify a developer station of a suction stroke if a developer station has already been assigned the suction permission for the same toner storage container.
- the suction cycle manager can be realized in such a way that, after a predetermined number of suction cycles allocated to a developer station, it removes the suction seal (compulsory break), e.g. he can withdraw the suction permission from a developer station after two suction cycles. During a forced pause, the suction manager may issue the suction permission to another developer station dispensing a suction request.
- the suction cycle manager then examines the suction requirements in the order of their storage in the first FIFO memory as to whether they can be given a suction permission. This is the case if no other developer station has already been assigned the suction permission and if the developer station to be tested does not deliver any toner (delivery cycle).
- the developer station under test If the developer station under test is in the process of delivering toner, it will not be given a suction permit. After completion of the delivery cycles of the developer station to be tested, its suction request can instead be stored in a second FIFO memory. Then, in the examination of the suction permission of the other in the first FIFO
- Memory stored suction requests from other developer stations first examines whether a suction request of a developer station stored in the second FIFO memory is present and in this case satisfies them before the suction request of the developer stations stored in the first FIFO memory.
- the future toner requirement of the developer stations can e.g. be determined on the basis of the charge images to be developed in the future;
- the priority in the allocation of a suction permission can be assigned according to a rigid criterion.
- the criterion may e.g. after a predetermined number of
- Delivery files are available at a developer station.
- the allocation of a suction permission can take place despite the above criterion at a developer station to another developer station, if the suction requirement of this developer station for the printing operation has higher priority.
- the priorities of all developer stations placing a suction request can be examined and the suction permission given to the developer station, which has the greatest importance for the maintenance of the printing operation.

- Fig. 6 is a flow chart illustrating, as an example, the processing of suction requests from multiple developer stations.
- FIG. 1 shows the representation of a toner supply in an electrographic printing device DR
- the other, in particular electrical and mechanical Structure eg paper transport device, transfer station, fixing unit, device control
- the printing device DR has as an example two printing units A and B, each containing developer stations EWS.
- the other electromechanical or physical structure of Druckwer- A and B is assumed to be known.
- the printing device DR is shielded from the outside mechanically and possibly electrostatically at least largely by an outer cladding AVK attached to it.
- the developer stations are shown 1 to 10, which serve in a known manner for the development of charge images, which have been generated for example on a photoconductor as an intermediate carrier.
- Developer stations 1 to 10 each contain developer which has at least toner which is used for coloring the charge images.
- the toner can be of different color to produce color images.
- the development of the charge images consumes toner, which must be supplemented during operation.
- three toner reservoir TF 11, 12, 13 are provided in Fig. 1, which are placed outside the printing device DR and the outer lining AVK and connected via toner transport channels 14, 15, 16 with developer stations. Toner can be transported into the developer stations via these toner transport channels 14, 15, 16.
- a vacuum system can be provided as described in more detail in WO 00/19278 and sucked by negative pressure in the toner transport channels the toner in the associated developer stations;
- the toner transport channels are suction channels. They can be made of flexible material, for example as hoses.
- the toner reservoirs 11-13 are respectively arranged in toner transport units ETT 17 to 19 to facilitate transporting them. Then, the single toner transport unit 17 to 19 must have a port for the toner transport channel connected to the respective toner reservoir.
- the toner reservoir 11 is connected to the developer station 2 and 6 via the toner transport channel 14, the toner reservoir 12 is connected to the developer station 4 and 7 via the toner transport channel 15, whereas the toner reservoir 13 is only via the toner transport channel 16 connected to the developer station 10.
- the developer stations which are not connected to external toner supply containers, are internally supplied with toner, e.g. by internal toner reservoir, which are connected via toner transport channels to the developer station, or the toner is manually supplemented by the operator toner is filled from a container according to DE 10 2004 039 678 in the developer station.
- toner supply to the developer stations EWS There are thus three possibilities of toner supply to the developer stations EWS:
- each toner reservoir 11 to 13 is each provided with a memory-containing first circuit 20, each
- Toner transport unit 17 to 19 each having a second memory circuit 21 and the Ent- Winding stations 1 to 10 each provided with a third memory circuit 22 having memory.
- the memory of the first circuit 20 may, for. B. arranged on the toner reservoir transponder according to WO 00/19278 be.
- the circuits contain at least information about the toner contained in the components of the toner supply (developer stations, toner reservoirs, toner transport units) and its color.
- the circuits 21, 22 may also include a software control program and a microprocessor. The exchange of information between the toner supply containers or the toner transport units and the developer stations EWS can take place via electrical connection lines 23
- connection- line Take place, which connect the toner reservoir TF and toner transport units ETT with the associated developer stations EWS.
- These connecting lines 23 may, for. B. are wound around the toner transport channels, the in Fig. 1, this is represented by oblique lines on the toner transport channels 14-16.
- the printing device DR can be used e.g. Determine which toner transport unit or toner reservoir is connected to which developer station and determine whether the toner reservoir is related to the color of the right developer station.
- the connection line can also be used only to determine whether a toner reservoir or a toner transport unit with the associated developer station EWS is connected via a toner transport channel.
- the circuits 20, 21 of the toner reservoir TF and the toner transport units ETT can continue to be connected via a bus 24 to a SubSteuermodul 25, the polls and collects the information from the first and second celts 20, 21.
- the sub-control module 25 is connected to a main control module 26, which is also connected to the third circuits 22 of the developer stations EWS.
- the main control module 26 thus receives information about the state of the developer stations EWS and the toner reservoir TF and toner transport units ETT. From this information, it is possible to control the printing device DR, eg to issue error messages if the toner supply of the developer stations is disturbed. It is convenient if the main control module displays the state of toner supply on a control panel BDF to the operator, e.g. B. with a graphical menu.
- the exchange of information between the toner supply containers TF and the developer stations EWS is particularly expedient when a new toner supply container is used in a toner transport unit.
- the color of the new toner may be changed compared to that of the previously used toner (old toner).
- all components of the transport path used by the old toner must be exchanged or cleaned for the developer station. This is especially true for the toner transport channel and the connection components for the
- step S21 the previously used toner reservoir TF is taken out of the toner transport unit ETT.
- step S22 the operator is prompted to Toner transport channel between the toner transport unit ETT and the developer station to clean.
- step S23 a new toner supply tank TF is set in the toner transport unit ETT.
- step S24 it is checked whether the first circuit of the toner storage tank TF is readable. If this is not the case, a corresponding message is output in step S25 and the operator is requested in step S26 to set a readable toner reservoir TF in the toner transport unit. If the step S24 shows that the toner storage tank TF is readable, it is checked in step S27 whether the color of the toner in the used toner storage tank TF is the desired color. If this is not the case, step S23 is repeated. If this is the case, the toner color can be output from the control panel (step S28). The toner color is finally written in the second circuit (step S29).
- the new toner color can not be written into the second circuit of the toner transport unit until the toner transport channel has been previously cleaned. By polling the second circuit can thus be determined whether this has been done, since then the toner color in the circuits of the developer station EWS, the toner reservoir TF and the toner transport unit ETT agrees.
- the toner transport unit ETT can be realized as a transport container into which the toner supply container is inserted in such a way that toner can be sucked out of its outlet opening into the toner transport channel attached to the toner transport unit via a connection arranged in the toner transport unit.
- the toner reservoir and the connection in the toner transport unit can be designed according to DE 10 2004 039 678. This publication is hereby incorporated by reference into the present specification. In the following, the configuration of the components of the toner supply and in particular their function will be further explained:
- toner transport units ETT e.g. 9 toner transport units
- the power supply (the power supply is located in the printing device DR) and the data transfer are realized via the bus 24.
- the purpose of the toner transport units ETT is to supply toner to the developer stations EWS. For this purpose, they are provided with a toner transport channel 14-16, e.g. a Tonersaugschlauch, connected to the associated developer station. To the toner transport channel next to a ground line, the so-called. Ping line 23 (connecting line) is wound.
- the developer stations EWS and the sub-control module 25 for the toner transport units ETT are connected via the bus 24 to the main control module 26, whereby the "information circuit" is closed.
- the ping signal over the connection lines 23 can be realized by: a simple pulse, or a complex sequence of changing electrical signals.
- the possibilities of change are the length, the intensity, the polarity and the temporal change of the signals. These variations can be used to make unique
- a toner transport unit ETT connected to the sub-control module 25 can not be equipped with a developer station EWS, a developer station EWS or one or more, e.g. two, developer stations EWS be connected.
- the toner color or the toner name is also stored in a second circuit on the toner transport unit ETT (second circuit 21). This information is important because it detects any build-up to the toner supply and prevents errors and contamination.
- the current situation of the toner supply (the components: developer station EWS, toner transport unit ETT, toner reservoir TF) is registered and processed in the printing device DR. According to the detected configuration of the components, displays (e.g., in menus), warnings, errors are displayed in the BDF panel.
- This z For example, proceed as follows:
- Circle B Toner Transport Unit ETT Toner Reservoir TF. According to the review of the two circles will be in
- the printer DR Due to the various possibilities that indicate how the individual developer stations EWS can be supplied with toner, it is important that the printer DR knows the configuration of the components with regard to the toner supply. For this purpose, the printer device DR, the main control module 26, has an interrogation method by which the given toner supply system is detected and corresponding error messages are output when errors occur.
- FIG. 3 When the printing device DR is turned on, a sequence (FIG. 3) is started by the main control module 26, which records the configuration of the printing device DR with respect to the toner supply. The data of the following components of the toner supply are successively recorded:
- step S1 Developer stations (for all developer stations EWS) -> EWS test (step S1):
- the connections between the toner transport units ETT and the developer stations EWS are queried.
- step S After each step S, the result is displayed on the control panel.
- FIG. 4 there is shown a flowchart showing the operation of a Saugtaktmanagers, which is integrated in the main control module.
- the Saugtaktmanager is responsible for coordinating the suction requirements of the developer stations EWS.
- the Saugtaktmanager is active when toner demand has been registered by one or more developer stations EWS (Suction request step S5 and S6).
- the developer stations EWS transmit their suction requirements to the suction cycle manager (step S7).
- the suction cycle manager coordinates the suction requirements and gives the suction permission to a developer station (step S8). In suction cycles, the toner is supplied to the developer station (step S9).
- FIG. 5 shows in a time diagram the allocation of the suction permission to eg three developer stations EWS1 to EWS3 through the suction cycle manager.
- the developer station EWSl (first line) reports toner consumption in a first cycle (time duration eg one second) (suction requirement tl).
- the suction cycle manager gives the developer station EWSl the suction permission for eg two suction cycles stl and st2 (filled in black).
- the developer station EWS2 (line 2) sets a suction request t2.
- the developer station EWS2 must wait until the suction cycles stl and st2 for the developer station EWSl are over.
- the suction cycle manager of the developer station EWS2 issues the suction permission for two suction strokes st3 and st4. If now the developer station EWSl delivers the next suction request t3, it must first wait for the suction permission. In the waiting time, the developer station EWSl toner for the development of charge images promote (dashed bars Ft). In the meantime, the developer station EWS3 has submitted a suction requirement t4. This is preferred to the suction requirement t3 since the developer station EWS3 has not yet been supplied with toner and the developer station EWS1 is still working with toner. In suction cycles st5 and st ⁇ the developer station EWS3 receives the suction permission.
- the suction request t3 of the developer station EWS1 is operated by the suction cycle manager and this is assigned the suction permission for the suction cycles st7, st8, since no further
- clocks of 1 second each have been selected as an example.
- the clocks may also have a different duration or be of different duration.
- a suction permission is issued over a larger number of suction cycles.
- the suction permission is not given in the order of receipt of the suction requirements. Rather, the aim is to serve the developer stations according to their toner requirements. Accordingly, the developer station EWS3 is given the suction permission earlier than the developer station EWS1, although it has previously made a suction request.
- the suction requirements of the developer stations can thus be assigned priorities that are chosen so that the operation of the printing device is optimized. When prioritizing the following factors can be taken into account: • The expected toner consumption of the individual developer stations, this can be determined from the data to be printed.
- the delivery cycles can also be prioritized and this taken into account when allocating the suction cycles to the developer stations. This determines which process (sucking or conveying) is more important at the respective developer station.
- the priorities can also be assigned according to rigid rules. For example, the Saugtaktmanager forgives a suction permission to a developer station, if, for example, has not been supplied with toner for 10 promotion files.
- the priority assignment can also be done dynamically.
- the individual factors influencing the toner supply are not considered in isolation, but an evaluation of these factors takes place at all developer stations. For example, a developer station has been operating for 10 not supplied with toner, then it is possible that this developer station not deviating from the above example receives the highest priority, for example, because the toner concentration of another developer station has dropped too much and threatened with an error therefore.
- the operation of the Saugtaktmanagers will be explained with reference to FIG. 6.
- the developer stations e.g. the developer station X, reports a suction request tl (step S10).
- the suction requirements of the developer stations are stored in the order of arrival at the suction cycle manager in a FIFO memory A.
- the suction requirement tl first stored in the FIFO memory A is subsequently processed; It is determined whether a suction request is contained in a second FIFO memory B (step S11). It is first assumed that this is not the case. Then, the suction request tl receives a first suction permission permission (step S12).
- step S13 it is determined whether another developer station is sucking toner, as long as this is the case, the suction request tl can not be operated. If this is not the case, the suction request tl receives a second suction permission permission (step S14).
- step S15 it is examined whether the developer station with the suction request tl is currently delivering toner. If this is not the case, the suction request tl is approved by the suction cycle manager (step S16) and the corresponding developer station X receives the suction permission. Now, the developer station X is prohibited from conveying toner (step S17), and can suck toner from a toner reservoir into suction cycles (step S18). After expiration of the suction cycles, the toner conveying block is canceled again (step S19).
- step S15 If it is determined in step S15 that the developer station X is currently conveying toner, it is waited in a step S20 until the conveyance cycles are completed, and then the suction request tl stored in the FIFO memory B.
- step S If during the further processing of the suction requests from the FIFO memory A, a suction request from the FIFO memory B is present at step S, then this is advanced (step S12) and the suction request from the FIFO memory A must wait. Only when all suction requests from the FIFO memory B have been processed can a suction request from the FIFO memory A be operated again.
- Fig. 6 shows an example of how the suction cycle manager can handle the suction requirements of multiple developer stations.
- the invention is not limited to this embodiment. Rather, the operation of the Saugtaktmanagers can be adapted to the particular structure of the printing device and their desired operation.
