Definitions
- the filling of consumables from a container in a receiving means is particularly important in electrographic printing devices.
- the function of such a printing or copying device is e.g. from WO 00/19278 known.
- WO 00/19278 known.
- 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 to charge new toner into the developer station. In addition, it is described how the content of the container for the toner, e.g.
- the toner transport connection between the developer station and the toner container is made by a toner transport channel to 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 transport channel is connected to the assigned developer station and the correct toner container.
- DE 102 23 206 A1 describes an apparatus and a method for dosing toner material in an electrophotographic printer.
- the developer station of each printing Council of the printer has a buffer for toner from which the toner can be transported to the developer station.
- the toner in the buffer is filled from a toner reservoir from which toner can be sucked into the buffer.
- a toner supply container With a toner supply container, two developer stations can be supplied with toner.
- a common suction device is used, which generates by means of valves either in one or the other developer station a suction force through which toner is sucked into the corresponding developer station.
- the first toner requesting developer station receives first the suction cycle, then the other developer station.
- This alternating suction cycle allocation ends when one of the developer stations reports that their toner requirements are met. Then only the other developer station is assigned the suction cycle.
- the allocation of the suction cycle to the developer stations thus takes place according to a rigid scheme in which special features in the operation of the developer stations or the printing device are not taken into account.
- DE 103 28 600 A1 deals with a device for conveying toner from a toner reservoir into the developer station of an electrophotographic printer.
- the toner reservoir is located outside the developer station. Toner from the toner reservoir is sucked into a toner buffer as needed and from there to the developer station.
- a transponder is arranged on the toner reservoir, in which the data of the toner are stored.
- US 2003/198487 A1 discloses an arrangement for filling toner from toner supply containers in developer stations of an electrophotographic printing device connected to the toner supply containers.
- a developer station When a developer station generates a toner request because the toner in the developer station has dropped too much toner is transported in a requested amount from the toner reservoir into the developer station.
- US 2003/198487 A1 is primarily concerned with the problem of toner toning in the toner reservoirs. To this end, it is proposed that during the toner transfer pauses to the developer stations, air from an air source be sequentially pumped into the toner reservoir to agitate the toner.
- WO 2000/019 278 A1 describes an arrangement in which it is prevented that incorrect toner is introduced into a toner reservoir or in which incorrect toner is prevented from being introduced from a toner reservoir into a developer station.
- a memory e.g. a transponder, in which the data of the toner are stored.
- Toner is introduced from the toner supply container into the developer station it is checked on the basis of the content of the memory whether the toner suitable for the developer station is contained in the toner supply container.
- EP 1 584 990 A1 discloses a device for supplying an electrophotographic color printing device with toner.
- the developer stations of the printing device which are arranged in a housing, are supplied with toner from toner supply bottles, which are arranged outside the printing device in a transport device.
- the toner supply bottles are each connected via a toner transport channel with the associated developer station.
- the toner transport from the toner supply bottles into the respective developer station is controlled by sensors which are arranged in the developer station and measure their fill level with toner. If the toner level falls below the sensor, new toner is sucked from the associated toner supply bottle into the developer station.
- the problem to be solved by the invention is to ensure the toner supply from a plurality of tooterror containers in an electrographic printing device, which may also have a plurality of printing units, each with a plurality of developer stations.
- the electrographic printing device thus provides at least one printing unit which has developer stations, by means of which toner charge images formed on an intermediate carrier are colored.
- 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 assigns the supply permits to the developer stations.
- a suction device can be provided as a toner transport device, which transports toner from the toner storage 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 cycle manager coordinates the suction requirements of the developer stations and informs the developer stations of the suction permission
- the Saugtaktmanager 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 do this
- 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 is not at the same time e.g. Toner promotes the development of charge images (delivery cycle). However, the suction cycle manager does not notify a developer station of a suction cycle if the suction permission for the same toner storage container has already been allocated to a developer station.
- the suction cycle manager can be realized such that it withdraws the suction permission after a predetermined number of suction cycles assigned to a developer station (compulsory break); Winder station after two suction cycles remove the suction permission. During a forced pause, the suction manager may issue the suction permission to another developer station dispensing a suction request.
- these can be stored in a first FIFO memory in the order of their input at Saugtaktmanager.
- 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 toner for the development of charge images (delivery cycle).
- the developer station under test is in the process of delivering toner, it will not be given a suction permit.
- its suction request can instead be stored in a second FIFO memory. Then, when checking the suction permission of the other suction stations of other developer stations stored in the first FIFO memory, it is first examined whether there is a suction request of a developer station stored in the second FIFO memory and in that case this is stored before the suction request in the first FIFO memory Developer stations met.
- 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 predetermined, in particular rigid criterion.
- the criterion may e.g. after expiration of a predetermined number of delivery cycles 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.
- a plurality of printing units each with a plurality of developer stations.
- the toner supplementation can then take place by toner reservoirs arranged outside of the printing units or printing device, which are each connected via a toner transport channel to a developer station or a plurality of developer stations, which are one or more Can be assigned to printing units.
- toner in the developer stations in addition to the arranged outside the respective printing unit toner reservoirs provide additional toner reservoir within the printing units, which are connected via an internal toner transport channel with the developer stations.
- the toner reservoirs arranged outside the printing units are mounted on a toner transport unit, so that they are easily movable.
- the toner storage containers may be provided with a memory having a first circuit in which at least the color filled in the associated toner reservoir is stored.
- the color information can be stored in a transponder arranged on the toner reservoir.
- the toner transport units can each be assigned a second circuit with a memory in which at least the toner ink filled in the associated toner reservoir is stored.
- a third circuit with a memory can be provided per developer station, in which at least the filled toner color is stored.
- electrical connection lines ping lines
- the connection lines (ping lines) can also be used only to query which Developer station is connected to which toner transport unit and arranged therein toner reservoir.
- 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 reservoirs.
- 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 circuit and the main control module, which detects at least the colors stored in the circuits of the toner transport units and toner reservoirs and transmits them to the main control module. From the information provided by the developer stations and the sub-controller module, the main control module can recognize which toner supply container is connected to which developer station.
- the main control module 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 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 will display a color change on the control panel.
- the main control module generates an error signal when, during color change within a toner transport unit or insertion of a toner reservoir of a different color into the toner transport unit, the components between the toner reservoir and developer station over which the preceding ink has been transported have not been cleaned or replaced. This prevents the toner of other color from being contaminated by the ink residues in these components. It is particularly important in this case 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 interrogation 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 via the bus, the 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.
- the toner transport units can then be checked,
- toner transport unit which toner color is stored in the toner transport unit; thereby it can be determined which toner color should contain a toner supply container which is inserted into the toner transport unit, since only from such toner supply containers toner may be conveyed into the associated developer station. Furthermore, the functionality of the toner transport units can be checked to see if
- a toner reservoir is used, - The toner transport channel is operatively connected.
- 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 master control module checks to see if the toner colors in the associated developer stations, toner reservoirs, toner transport units match, firstly verifying the developer station and the toner transport unit and then the toner transport unit and the toner reservoir is performed. It is expedient if the main control module inhibits the printing operation if the toner colors of the associated developer station, toner transport unit or toner reservoir do not match.
- the main control module should query the respective developer station and its circuit as to how its toner supply (manually, by vacuum) 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.

- the printing device DR has as an example two printing units A and B, each containing developer stations EWS.
- the printing unit A has the developer stations 1 to 5 and the printing unit B the developer stations 6 to 10.
- the other electromechanical or physical structure of the printing units A and B is assumed to be known.
- the printing device DR is mechanically shielded to the outside and possibly electrostatically at least largely by an outer cover AVK attached to it.
- the developer stations 1 to 10 are shown, which are used in a known manner for the development of charge images, which have been produced 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.
- an accident tertiksystem be provided as it is described in more detail in WO 00/19278 and sucks the toner in the associated developer stations by negative pressure in the toner transport channels;
- 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 connected to the developer station 10.
- 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 supply by internal toner reservoirs,
- each toner reservoir 11 to 13 each with a memory containing first circuit 20, each toner transport unit 17 to 19 each having a second memory circuit 21 and the Developer stations 1 to 10 each provided with a third memory circuit 22 having memory.
- the memory of the first circuit 20 may, for.
- a transponder arranged on the toner reservoir can be corresponding to WO 00/19278.
- 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 reservoirs or the toner transport units can be via electrical
- Connecting lines 23 take place, which connect the toner reservoir TF or toner transport units ETT with the associated developer stations EWS. These connecting lines 23 may, for. For example, in FIG. 1, this is represented by oblique strokes on the toner delivery channels 14-16.
- the connection lines 23 the information contained in the first and second circuits can be supplied to the developer stations.
- the printing device DR can determine, for example, which toner transport unit or toner reservoir is connected to which developer station and thereby determine whether the toner reservoir is related to the color with the right developer station.
- the connection line can also be used only to determine whether a toner supply container or a toner transport unit with the associated development 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 with a SubSteuermodul 25, which retrieves the information from the first and second cascade circuits 20, 21 and collects.
- 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. It can control the printing device DR from this information, e.g. Give error messages if the toner supply to 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 useful when a new toner supply container is used in a toner transport unit.
- the color of the new toner may be changed in comparison with that of the previously used toner (old toner).
- all components of the transport path used by the old toner must be replaced or cleaned at the developer station. This is especially true for the toner transport channel and the connecting parts for the toner transport channel to the Tonvorrats employer. If this replacement or cleaning has not been carried out, the new toner must not be transported to the developer station.
- step S21 the previously used toner storage container TF is removed from the toner transport unit ETT.
- step S22 the operator is prompted to clean the toner transport channel between the toner transport unit ETT and the developer station.
- step S23 a new toner reservoir 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.
- step S25 a corresponding message is output in step S25 and the operator is requested in step S26 to set a readable tooterror container TF in the toner transport unit.
- 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 S 29). 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 or replaced. By querying 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 match.
- 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 from its outlet opening via a connection arranged in the toner transport unit into the toner unit attached to the toner transport unit. Transport channel can be sucked.
- 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.
- 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 Tonersaugschlauch 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 via 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 to be connected.
- the toner color or the toner name is also stored on the toner transport unit ETT (second circuit 21) on a memory module. 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:
- Menus graphically display the current situation of the components, including the existing toner transport channels.
- the color matches are checked.
- the toner color of the developer station EWS, the toner transport unit ETT and the toner reservoir TF to ensure proper operation.
- Circle A Developer station EWS - toner transport unit ETT
- Circle B Toner transport unit ETT - Toner tank 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):
- step S2 How many toner transport units are available? Which colors are assigned to the toner transport units?
- 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 suction cycle manager 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 e.g. three developer stations EWSl to EWS3 through the suction cycle manager.
- the developer station EWS1 (first line) reports toner consumption in a first cycle (time duration, for example one second) (suction request tl).
- the suction cycle manager gives the developer station EWS1 the sucker license for e.g. two suction strokes 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 permit 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, if a developer station has not been supplied with toner for 10 delivery cycles, then it is possible that this developer station does not receive the highest priority, in deviation from the example above, since, for example, the toner concentration of another developer station has fallen too low and an error message threatens.
- the operation of the Saugtaktmanagers will be explained with reference to FIG. 6.
- the developer stations eg the developer station X, announces 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). To Expiration of the suction cycles, the toner delivery block is canceled (step S19).
- step S15 If it is determined in step S15 that the developer station X is currently conveying toner, in a step S20 it is waited until the conveyance cycles are finished, and then the suction request tl is 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 again a suction request be operated from the FIFO memory A.
- 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.
- the invention is suitable for use in various types of printing devices, in particular in electrographic printing devices, which include, for example, electrophotographic printing devices, magnetographic printing devices and ionographic pressure devices, but these are not limited to these.
- electrographic printing devices which include, for example, electrophotographic printing devices, magnetographic printing devices and ionographic pressure devices, but these are not limited to these.
