Description

[Technical Field]

[0001] The present invention relates to an inkjet printer system, and more particularly to an inkjet printer system equipped with a plurality of continuous jet charge-controlled inkjet recording devices. [Background technology]

[0002] A typical continuous-jet, charge-controlled inkjet recording device has an ink container in its main body that stores ink, and supplies the ink from the ink container to the print head via an ink supply pump. The ink supplied to the print head is continuously ejected from ink nozzles to form ink droplets. Among the ink droplets, those used for printing are charged and deflected, and then propelled to the desired printing position on the print target to form characters or symbols. Ink droplets not used for printing are not charged or deflected, but are collected in an ink recovery section (gutter) and returned to the ink container via an ink recovery pump.

[0003] In addition, in the production lines of large-scale production factories that manufacture products such as packaging containers containing food and PET bottles filled with beverages, multiple inkjet recording devices are installed to print expiration dates, manufacturing plants, serial numbers, etc. on the surfaces of many products. In this way, in inkjet printer systems equipped with multiple inkjet recording devices, the printing specifications for expiration dates, manufacturing plants, serial numbers, etc. must be changed to suit the products, and for this reason, it is known to connect the multiple inkjet recording devices to a server via transmission lines and change the printing specifications for the multiple inkjet recording devices.

[0004] A method for changing the printing specifications of multiple inkjet recording devices is known, for example, from Japanese Patent Application Laid-Open No. 2020-26057 (Patent Document 1). In this patent document, multiple inkjet recording devices are connected to a server via a transmission line. The optimal printing specifications obtained for a specific inkjet recording device are then transmitted to the server via the transmission line. This allows the server to retrieve these optimal printing specifications and provide the optimal printing specifications to other inkjet recording devices. In this way, the other inkjet recording devices can perform high-quality printing even if they do not have the functionality to determine the optimal printing specifications.

[0005] [Patent Document 1] Japanese Patent Publication No. 2020-26057 Summary of the Invention [Problem to be solved by the invention]

[0006] In such inkjet printer systems, the operator must input setting value information such as initial values ​​when starting operation of the inkjet recording device. For example, setting value information such as ink pressure, charging voltage, deflection voltage, and excitation frequency is set by the operator operating an input panel to set temporary setting value information, and then a test print is performed. When it is determined that the print is appropriate, the setting value information is registered as appropriate setting value information by operating the input panel.

[0007] However, when there are multiple inkjet recording devices, the setting value information must be configured for each inkjet recording device. This requires a lot of time from the operator and increases the risk of incorrect settings. Furthermore, when a server is used as a host device, it is necessary to configure the server and to wire the server to each inkjet recording device, which necessitates the construction of a large-scale communication facility.

[0008] An object of the present invention is to provide an inkjet printer system that can quickly set setting values ​​for multiple inkjet recording devices in a short amount of time without the risk of incorrect setting, and that does not require the construction of large-scale communication equipment. [Means for solving the problem]

[0009] The present invention is an inkjet printer system comprising a master inkjet recording device and a slave inkjet recording device, wherein the respective control means of the master inkjet recording device and the slave inkjet recording device are connected by a master wireless terminal and a slave wireless terminal which are capable of communicating with each other, and wherein setting value information of the master inkjet recording device is set by operation on an input panel of the master inkjet recording device, and operation information for setting the setting value information on the input panel of the master inkjet recording device is sent from the master wireless terminal of the master inkjet recording device to the slave wireless terminal of the slave inkjet recording device, and the slave inkjet recording device sets the setting value information of the slave inkjet recording device using the received operation information in the same operation procedure as the master inkjet recording device. [Effects of the Invention]

[0010] According to the present invention, operation information from the master inkjet recording device is sent to the slave inkjet recording device via a wireless terminal, and setting value information is set in the master inkjet recording device and the slave inkjet recording device using the same operating procedure. This makes it possible to quickly set setting value information in multiple inkjet recording devices in a short amount of time without the risk of incorrect setting, and it is possible to provide an inkjet printer system that does not require the construction of large-scale communication equipment.

[Figure 2] 1 is a configuration diagram showing an embodiment of an inkjet printer system of the present invention; [Figure 3] 10 is a flowchart showing a process for setting setting value information in the master inkjet recording device. [Figure 4] 10 is a flowchart showing a process for setting setting value information in a slave inkjet printing apparatus. DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiment, and various modifications and application examples within the technical concept of the present invention are also included within its scope.

[0013] 1 is a diagram showing the configuration of an inkjet recording device according to the present invention. The inkjet recording device comprises a recording device main body 100 and a print head 200. The print head 200 is installed so as to face the conveyance path of a printing target 500 conveyed by a conveyor 400 on a production line.

[0014] The recording device main body 100 is equipped with a microcomputer (hereinafter referred to as MPU) 101 that controls the entire inkjet recording device, a read-only memory (ROM) 102 that stores control programs and data necessary for the MPU 101 to operate, and a rewritable temporary memory (RAM) 103 that temporarily stores data required by the MPU 101 while the program is running.

[0015] The temporary storage memory 103 has a storage area for storing operation information, which will be described later, and operation information input from the input panel 104 is transferred via a bus line 106 and temporarily stored therein. This transfer and storage control is executed by the MPU 101. These devices function as "control means."

[0016] Furthermore, the inkjet recording device is also equipped with an input panel 104 that performs operations for inputting print content, setting value information, etc., and a display device (browser) 105 that displays the input setting value information and print content, etc. The input panel 104 and display device 105 use a touch input display panel in which transparent touch switches are superimposed on the surface of a liquid crystal display screen.

[0017] Operation information and setting value information set by the operation on the input panel 104 are transferred to the temporary storage memory 103 via a bus line 106. Furthermore, the bus line 106 transmits data signals, address signals, control signals, etc. from the MPU 101.

[0018] The print head 200 is provided with a charging electrode 203 surrounding the position where ink liquid 109, which is supplied under pressure from an ink container 107 in the recording device main body 100 by an ink supply pump 108, is ejected from a nozzle 201 in the form of an ink pillar 109a, the tip of which separates to form an ink droplet 109b.

[0019] Furthermore, the device is provided with a deflection electrode 204 that generates a deflection electric field that deflects the flying, charged ink droplets 109b according to the amount of charge and directs them toward the printing target 500 for printing. It also has a gutter 205 that captures ink droplets 109b that were not used for printing, and a phase detection sensor (hereinafter referred to as an auto phase sensor) 206 that generates a phase detection signal according to the amount of charge of the ink droplets 109b captured by the gutter 205.

[0020] The recording apparatus main body 100 is further provided with a pump drive circuit 111 that controls the ink supply pump 108 and an ink recovery pump 110 that recovers the ink droplets 109b captured by the gutter 205 into the ink container 107. It is also provided with an excitation voltage generation circuit 112 that excites an electrostrictive element 202 built into the print nozzle 201 in order to provide regularity to the timing at which the ink pillar 109a ejected from the print nozzle 201 separates into ink droplets 109b.

[0021] Furthermore, there are provided a D / A converter 115 that converts the digital signal-form charging signals output from the printing charging signal generating circuit 113 and the phase search charging signal generating circuit 114 into analog voltage signals, and an amplifier circuit 116 that amplifies the analog signal-form voltage signals output from the D / A converter 115 to generate a charging voltage to be applied to the charging electrode 203.

[0022] Furthermore, the circuit is provided with a deflection voltage generation circuit 117 that generates a deflection voltage to be applied to the deflection electrode 204, an amplifier circuit 118 that amplifies the phase detection signal in the form of an analog signal output from the auto phase sensor 206, a phase determination circuit 119 that receives the amplified phase detection signal and determines whether charging is normal, and an A / D converter 120 that receives the amplified phase detection signal and performs A / D conversion.

[0023] In the inkjet recording apparatus configured as described above, the MPU 101 controls the pump drive circuit 111 via the bus line 106 to operate the ink supply pump 108 and the ink recovery pump 111, thereby sucking and pressurizing the ink 109 in the ink container 107 and supplying it to the print nozzle 201, causing an ink pillar 109a to be ejected from the print nozzle 201, and sucking up the ink droplets 109a captured by the gutter 205 and recovering them in the ink container 107.

[0024] The tip of the ink pillar 109a ejected from the nozzle 201 separates to become an ink droplet 109b. The timing at which the tip of the ink pillar 109a separates into an ink droplet 109b can be regulated to a predetermined phase relative to the excitation voltage by generating an excitation voltage using the excitation voltage generating circuit 112, which excites the electrostrictive element 202 of the print nozzle 201 and vibrates the ink pillar 109a.

[0025] The amount of charge on ink droplet 109b is proportional to the amount of charge on ink pillar 109a due to the potential of charging electrode 202 when ink droplet 109b separates from the tip of ink pillar 109a. Printing charging signal generating circuit 113 generates a printing charging signal for applying a charging voltage to charging electrode 203 so that the amount of charge is sufficient to deflect ink droplet 109b to a predetermined position when the tip of ink pillar 109a separates into ink droplet 109b.

[0026] In response to the charging voltage generated based on the printing charging signal, the charged ink droplets 109b are electrostatically deflected while flying between the deflection electrodes 203, and land at predetermined positions on the printing target 500. The uncharged ink droplets 109b travel in a straight line and are captured and collected by the gutter 205.

[0027] The timing for generating the printing charging signal must be such that a charging voltage can be applied to the charging electrode 202 so that when the ink pillar 109a separates into ink droplets 109b, the amount of charge is sufficient to deflect the ink droplets 109b to a predetermined position.

[0028] As shown in FIG. 1, when the inkjet recording device detects the arrival of a print target 500 conveyed by a conveyor 400 on the production line, moving in front of the print head 200, the inkjet recording device generates a printing charging voltage that charges the ink droplets 109b, and deflects and controls the ink droplets 109b to print.

[0029] Then, during the non-printing period between the printing targets 500, a phase search charging voltage is generated to perform phase search. For this phase search, the phase search charging signal generating circuit 114 generates a charging signal for generating a plurality of phase search charging voltages with different phases relative to the excitation voltage. The phase search charging voltage has a magnitude that provides a deflection amount that prevents the charged ink droplet 109b from jumping over the gutter 205 (so that it can be captured by the gutter 205).

[0030] A phase detection signal output from the auto phase sensor 206 according to the charge amount of the ink droplet 109 b charged by this charging voltage is input to a phase determination circuit 119 and an A / D converter 120 via an amplifier circuit 118 .

[0031] Furthermore, a wireless terminal 121, which is a feature of this embodiment, is connected to the bus line 106. The bus line 106 can transfer operation information on the input panel 104 that is operated to set setting value information from the temporary storage memory 103 to the wireless terminal 121, or can transfer operation information received by the wireless terminal 121 to the temporary storage memory 103.

[0032] The operation information is information on input operations on the input panel 104 performed to set setting value information, and this operation information is stored in a storage area set in the temporary storage memory 103 in response to a command from the MPU 101. The operation information is, for example, information on operations associated with operating a deflection voltage setting button or inputting a setting value when setting a deflection voltage, and is operation information input to an input unit (not shown) in the browser of the input panel 104. In addition, this operation information is transferred to the temporary storage memory 103 via the bus line 106.

[0033] The setting value information set by the input panel 104 is also stored in the temporary memory 103, and the MPU 101 reflects this setting value information in the print data, and printing is performed based on this print data. In other words, the printing operation of the inkjet recording apparatus shown in FIG. 1 is performed.

[0034] Then, in response to a command from MPU 101, the operation information stored in temporary storage memory 103 is read out and transmitted from wireless terminal 121. Conversely, in response to a command from MPU 101, the operation information is received by wireless terminal 121 and stored in temporary storage memory 103. In this manner, wireless terminal 121 transmits the operation information read out from temporary storage memory 103, or receives the operation information and transfers it to temporary storage memory 103 for storage.

[0035] In this way, the setting value information of the inkjet recording device is set by operating the input panel 104 of the inkjet recording device, and the operation information for setting the setting value information on the input panel 104 of the inkjet recording device is stored in the temporary storage memory 103.

[0036] The operation information stored in temporary storage memory 103 is then sent from the wireless terminal 121 of the inkjet recording device to the wireless terminal 121 of the other inkjet recording device via bus line 106. In response, the other inkjet recording device stores the received operation information in temporary storage memory 103, provides this stored operation information to an input unit (not shown), and executes setting of the setting value information in the other inkjet recording device using the same operation procedure as the previous inkjet recording device.

[0037] In other words, the other inkjet recording device virtually operates the input panel 104, the setting value information set thereby is stored in the temporary storage memory 103, the MPU 101 reflects this setting value information in the print data, and printing is performed based on this print data.

[0038] In this way, in inkjet recording devices linked by a wireless terminal, setting value information can be set using the same operating procedure, so setting value information in multiple inkjet recording devices can be set quickly and in a short amount of time without the risk of incorrect setting, and an inkjet printer system can be provided that does not require the construction of large-scale communication equipment.

[0039] Next, an example of an inkjet printer system according to this embodiment will be described with reference to Figures 2 to 4. Figure 2 shows an example in which a master inkjet recording device and a slave inkjet recording device are connected by a wireless terminal 121 and setting value information is input. Figure 3 shows the process flow for setting setting value information in the master inkjet recording device, and Figure 4 shows the process flow for setting setting value information in the slave inkjet recording device.

[0040] FIG. 2 shows a configuration in which a plurality of slave inkjet recording apparatuses 800 and 900 are linked (coordinated) in parallel to one master inkjet recording apparatus 600.

[0041] The master inkjet recording apparatus 600 is provided with an input panel 601, a browser 602, a master wireless terminal 603, and a temporary storage memory 604. The master wireless terminal 603 is wirelessly connected to a network 700 such as a LAN.

[0042] The slave inkjet recording apparatus 800 is also provided with an input panel 801, a browser 802, a slave wireless terminal 803, and a temporary storage memory 804. The slave wireless terminal 803 is wirelessly connected to a network 700 such as a LAN. The slave inkjet recording apparatus 900 is also provided with an input panel 901, a browser 902, a slave wireless terminal 903, and a temporary storage memory 904. The slave wireless terminal 903 is wirelessly connected to the network 700 such as a LAN.

[0043] Here, the master inkjet recording apparatus 600 and the plurality of slave inkjet recording apparatuses 800 and 900 have the same configuration as the inkjet recording apparatus shown in FIG.

[0044] Then, the operation information input to the input section of the browser 602 by operating the input panel 601 is stored in a temporary storage memory 604 of the master inkjet recording device 600 (this temporary storage memory 604 is the same as the temporary storage memory 103 in Figure 1).

[0045] At this time, the information stored in temporary storage memory 604 is operation information related to the operation on input panel 601 and setting value information such as initial values ​​input at this time. Then, when the operation on input panel 601 is completed, the stored setting value information is reflected in the print data by MPU 101 (see FIG. 1), and printing is executed based on this print data.

[0046] Next, when the setting value information in the master inkjet recording device is determined and a transmission command is issued from the input panel 601, the MPU 101 reads out the operation information stored in the temporary storage memory 604, and the master wireless terminal 603 transmits the operation information to the network 700 via the bus line 106.

[0047] On the other hand, the operation information transmitted by the master wireless terminal 603 of the master inkjet recording apparatus 600 is received by the slave wireless terminals 803 and 903 of the slave inkjet recording apparatus 800 and the slave inkjet recording apparatus 900 via the network 700. The received operation information is stored in the temporary storage memory 804 of the slave inkjet recording apparatus 800 and the temporary storage memory 904 of the slave inkjet recording apparatus 900 via the bus line 106.

[0048] When the operation information is stored in the temporary storage memory 804, 904, the MPU 101 of the slave inkjet recording apparatus 800, 900 reads out the operation information and inputs it into the input section of the browser 802, 902 as if the input panel 801, 901 had been operated, and stores the same setting value information as that of the master inkjet recording apparatus in the temporary storage memory 804, 904.

[0049] In this way, the setting value information is set in the slave inkjet recording devices 800 and 900 using the same operating procedures as for the master inkjet recording device. The stored setting value information is then reflected in the print data by the MPU 101, and printing is performed based on this print data.

[0050] Furthermore, in addition to the setting value information, when ejecting or stopping ink from the print head 200, operation information from the master inkjet recording apparatus 600 can be sent to the slave inkjet recording apparatuses 800, 900, and the ink ejection or stopping operations of the master inkjet recording apparatus 600 can be performed directly on the slave inkjet recording apparatuses 800, 900. Therefore, the ink ejection and stopping operations can be performed without touching the input panels 801, 901 of the slave inkjet recording apparatuses 800, 900.

[0051] In this embodiment, operation information is sent in parallel to the slave inkjet recording apparatus 800 and the slave inkjet recording apparatus 900, and is not sent in series from the slave inkjet recording apparatus 800 to the slave inkjet recording apparatus 900. In other words, the slave wireless terminal 803 of the slave inkjet recording apparatus 800 is configured not to relay information to other slave wireless terminals 903 of other slave inkjet recording apparatuses 900.

[0052] This makes it possible to suppress delays in information transmission to the slave inkjet recording apparatus 900. Furthermore, since the slave inkjet recording apparatus 800 does not transmit information as a relay for the slave inkjet recording apparatus 900, it is possible to avoid collisions in communication of operation information.

[0053] In this embodiment, since the system uses wireless terminals 603, 803, and 903, even if a new inkjet printing device is added, there is no need to prepare a new cable to connect the inkjet printing devices, which reduces the cost burden of communication equipment.

[0054] Furthermore, communication using wireless terminals is more likely to be delayed as the amount of information increases compared to when cables are used. However, instead of transmitting the print data itself to the slave inkjet recording devices 800 and 900, the input panel 601 of the master inkjet recording device 600 exchanges operation information on how the device was operated, so the amount of information can be reduced and delays can be suppressed.

[0055] Furthermore, when adding other functions, it is necessary to add new communication protocols and other processing at the time of reception in addition to screen control as new communication messages. However, in the case of this embodiment, since the input panel operation processing is performed by communication, there is less need to add new processing at the time of reception.

[0056] Next, the process flow for setting the setting value information in the master inkjet recording apparatus 600 will be explained using Fig. 3. Incidentally, the communication of the operation information is as described above.

[0057] 3, when screen operation is started using the input panel 601, in "Step S10," it is determined whether or not there is an operation related to changing the setting value information. If it is determined that there is no operation related to changing the setting value (NO), the screen operation ends. On the other hand, if it is determined that there is an operation related to changing the setting value (YES), the process proceeds to "Step S11."

[0058] In "Step S11," it is determined whether or not the mode is collective control mode. This collective control mode means that the setting value information of the slave inkjet recording devices 800, 900 is also set at the same time. If it is determined that the mode is not collective control mode (NO), the inkjet recording device in question moves to "Step S14," where the input setting value information (see the explanation in FIG. 2) is reflected in the print data. In this step, the inkjet recording device has not yet been determined to be the master inkjet recording device 600.

[0059] Next, if it is determined that the mode is the collective control mode (YES), it is determined in "Step S12" whether the master inkjet recording device 600 is the one in question. In this embodiment, the master inkjet recording device 600 and the slave inkjet recording devices 800 and 900 are configured to be arbitrarily and selectively switchable. In other words, of the linked inkjet recording devices, one can be arbitrarily set as the master inkjet recording device, and the others as slave inkjet recording devices.

[0060] If it is determined in "Step S12" that the device is not the master inkjet recording device 600 (NO), the process proceeds to "Step S14" where the input setting value information (see the explanation in FIG. 2) is reflected in the print data. This assumes that even in the collective control mode, the slave inkjet recording devices 800, 900 are set independently.

[0061] On the other hand, if it is determined to be the master inkjet recording device 600 (YES), the process proceeds to "Step S13", where the master wireless terminal 603 transmits operation information from the input panel 601. Note that this is the operation information when the input panel 601 described in FIG. 2 is operated. After transmitting the operation information, the process proceeds to "Step S14", where the master inkjet recording device 600 reflects the setting information set by operating the input panel 601 in the print data. After that, the screen operation ends.

[0062] Next, the processing flow for setting the setting value information in the slave inkjet recording apparatuses 800 and 900 in the collective control mode will be described with reference to FIG.

[0063] When a transmission from the master inkjet recording apparatus 600 is received, it is determined in "Step S20" whether it is a slave inkjet recording apparatus. If it is determined that it is not a slave inkjet recording apparatus 800, 900 (NO), the process skips to the end of reception. This assumes that it is not linked to the master inkjet recording apparatus 600.

[0064] On the other hand, if it is determined that the device is the slave inkjet recording device 800, 900 (YES), the process proceeds to step S21, where the received operation information is stored in its own temporary storage memory 804, 904. Thereafter, the process proceeds to step S22, where the operation information is virtually displayed on the browser 801, 901 based on the received operation information. Thereafter, the process proceeds to "step S23." This allows the setting value information to be set using the same operation procedure as for the master inkjet recording device 600.

[0065] After "Step S22" is executed, in "Step S23", it is determined whether or not the setting value information set in "Step S22" has been changed. If it is determined that the setting value information has not been changed (NO), reception ends. This assumes that the setting value information newly set in the master inkjet recording device 600 is the same as the setting value information of the current slave inkjet recording device.

[0066] On the other hand, if it is determined in "Step S23" that the setting value information has been changed (YES), the setting value information (see the explanation of FIG. 2) is reflected in the print data in "Step S24".

[0067] Here, the slave inkjet recording devices 800, 900 can be configured so that if they do not execute the setting of the setting value information based on the operation information sent from the master inkjet recording device 600, the slave wireless terminal can be set to not receive the information.

[0068] As described above, according to the present invention, there is provided an inkjet printer system comprising a master inkjet recording device and a slave inkjet recording device, wherein the control means of the master inkjet recording device and the slave inkjet recording device are connected by wireless terminals capable of communicating with each other, and setting value information of the master inkjet recording device is set by operation on the input panel of the master inkjet recording device, and operation information for setting the setting value information on the input panel of the master inkjet recording device is sent from the master wireless terminal of the master inkjet recording device to the slave wireless terminal of the slave inkjet recording device, and the slave inkjet recording device sets the setting value information of the slave inkjet recording device using the received operation information in the same operation procedure as the master inkjet recording device.

[0069] In this way, the operation information of the master inkjet recording device is sent to the slave inkjet recording device via a wireless terminal, and the setting value information is set using the same operation procedure in the master inkjet recording device and the slave inkjet recording device. This makes it possible to quickly set the setting value information in multiple inkjet recording devices in a short amount of time without the risk of incorrect setting, and also provides an inkjet printer system that does not require the construction of large-scale communication equipment.
