BACKGROUND OF THE INVENTION
The present invention relates to a printing apparatus configured by combining a plurality of types of printing press main bodies, drum units, and ink bottles.
[0002]
[Prior art]
A stencil printing apparatus, which is a type of printing apparatus, includes a plurality of types of printing machine main bodies, a plurality of types of drum units, and a plurality of types of ink bottles. There is a configuration in which the drum unit suitable for the printing press main body is selected and installed, and the drum unit is suitable for the installed drum unit, and the desired ink bottle is selected and installed. This is because the printing performance differs depending on the structure of the printer main body (difference in resolution, how to apply printing pressure, etc.), and therefore, a drum unit and an ink bottle suitable for each different structure are mounted. In the case where the stencil printing apparatus is configured by such a combination, it is necessary to change the printing control of the printing machine main body or the like depending on the difference in the ink used (for example, black ink and color ink). For this reason, each of the printing press main body, drum unit, and ink bottle is provided with identification means such as an identification code, and the identification means such as the identification code is used to check for differences in the combination or to recognize those that are combined with each other. Depending on the situation, the contents of control were determined.
[0003]
For example, as shown in FIG. 8, there are four types of main body of the printing machine: a domestic 400 dpi model, an overseas 400 dpi model, a domestic 600 dpi model, and an overseas 600 dpi model, and the drum unit is a 400 dpi model ( Black and color are the same model in this specific example), and there are two types of 600 dpi models, and there are four types of ink bottles: 400 dpi black ink, 400 dpi color ink, 600 dpi black ink, and 600 dpi color ink. 1 to 4 model codes for the main unit, 1 and 2 type codes for the drum unit, and drum color code (indicating whether to use black or color as ink for the ink bottle) Each has a bottle code such as “100”.
[0004]
As shown in FIG. 7, for example, when a domestic 400 dpi model is selected as a printing machine body, a 400 dpi model is selected as a drum unit, and when black ink is used, a combination of 400 dpi black ink is selected as an ink bottle. It becomes. Since the main body of the printing press has a model code and has correspondence information with a drum unit conforming to the model code, for example, when a 600 dpi model is selected as a drum unit, a drum difference error can be detected. Since it has a code and a drum color code, and has correspondence information with a bottle unit that conforms to the code, for example, when 400 dpi color ink is selected as an ink bottle, an error in bottle difference can be detected. In addition, printing control suitable for the ink to be used can be performed when the printing press main body acquires the bottle code.
[0005]
Conventionally, an operator has input the identification code itself into the printing machine main body and the drum unit in the production process or the like in order to give the printing machine main body, the drum unit, and the ink bottle an identification code.
[0006]

The control means 3 is connected to the RAM 11, the ROM 12 as the main body side corresponding information memory, and the main body side code storage means 13, and is configured to control reading and writing of these data. The ROM 12 stores a program for executing the flow shown in FIGS. As will be described in detail below, the correspondence information between the model codes of all types of printing machine main bodies 1 and the drum codes of the drum unit 20 corresponding to the model codes is stored. The main body side code storage means 13 is composed of, for example, a non-volatile memory, and is configured to retain the stored contents even when the power is off.
[0020]
The control means 3 controls to execute the flow operations of FIGS. 2 and 3 in the identification code setting mode (consisting of the printer main body setting mode and the drum unit setting mode). This control content will be described below.
[0021]
Each drum unit 20 has a control unit 21, and a drum side communication unit 22 is connected to the control unit 21, and information can be exchanged with the printing press main body 1 through the drum side communication unit 22. ing. That is, the control unit 3 of the printing press main body 1 and the control unit 21 of the drum unit 20 can perform two-way data communication, and information necessary for the drum unit 20 among the information input to the operation panel 2 can be stored in the drum unit 20. The information in the main body side code storage means 13 can be transferred to the drum unit 20, and the information in the drum side code storage means 31 can be transferred to the printing machine main body 1.
[0022]
Detection information of the bottle set first switch 23, the bottle set second switch 24, and the bottle set third switch 25 is input to the control means 21, and the control means 21 is mounted according to the information of each of the switches 23, 24, 25. The ink bottle identification code may be acquired. Each switch 23, 24, 25 is mechanically turned on / off based on the identification code information of the ink bottle (not shown) to be mounted. Further, detection information of the ink presence / absence sensor 26, the ink temperature sensor 27, and the drum A detection sensor 28 is input to the control means 21, and the control means 21 detects the presence / absence of ink and the ink temperature based on the information of the sensors 26, 27, and 28. The information on the drum rotation position can be acquired. Further, the control means 21 controls the ink motor 32 in the print mode.
[0023]
The control means 21 is connected to a RAM 29, a drum 30 corresponding to a drum side information memory, and a drum side code storage means 31 so that reading and writing of these data can be controlled. The ROM 30 stores a program for executing the flow of FIG. 2B, FIG. 4, FIG. 5, FIG. As will be described in detail below, correspondence information between all types of drum codes and combinations of each type of ink itself and bottle codes of ink bottles corresponding to the combinations is stored. The drum-side code storage means 31 is constituted by, for example, a non-volatile memory, and is configured to hold the stored contents even when the power is off.
[0024]
The control means 21 performs the flow operation of FIGS. 2 and 4 in the identification code setting mode (consisting of the printer main body setting mode and the drum unit setting mode), and when the control means (CPU) of the drum unit 20 is on, FIG. And control to execute the flow operation of FIG.
[0025]
Next, the operation of the above configuration will be described. A worker processes the drum unit 20 that fits the desired printer main body 1. Then, the printer main body setting mode of the identification code setting mode is selected, and the operator inputs the model code of the printer main body 1 using the operation panel 2 as shown in FIG. 2A (step S1). . That is, if the printing press main body 1 is a domestic 400 dpi model, “1” is input. When the model code is input, the control means 3 shifts to a main body fixed value setting process (step S2).
[0026]
As shown in FIG. 3, the main body fixed value setting process checks whether the input model code is 1, 2, 3 or 4, and determines an available drum code (1 or 2) corresponding to the input model code. Derived (steps S10 to S17). Then, the derived usable drum code (1 or 2) and the inputted model code (1 or 2 or 3 or 4) are written in the main body side code storage means 13 (steps S18 and S19). If the input model code is neither 1, 2, 3, or 4, a model code setting error is detected (step S20), and this is displayed on the display means of the operation panel 2, for example.
[0027]
Next, the drum unit setting mode of the identification code setting mode is selected, and the ink (black or color) code used by the worker is operated as the drum color code (1 or 2) as shown in FIG. Input is performed using the panel 2 (step S3). That is, “1” is input when the stencil printing apparatus is to be used for black and white, and “2” is input when the stencil printing apparatus is to be used for color. When the drum color code is input, the control unit 21 proceeds to drum fixed value setting processing (step S4).
[0028]
In the drum fixed value setting process, as shown in FIG. 4, the control unit 21 transfers the usable drum code (1 or 2) of the main body side code storage unit 13, and this usable drum code (1 or 2). Is set as a drum chord (1 or 2) (steps S30, S31, S35, S36). If the drum code is “1” and the drum color code is “1”, “100” is set as the bottle code, and if the drum color code is not “1”, “010” is set as the bottle code. (Steps S32 to S34). If the drum code is “2” and the drum color code is “1”, “101” is set as the bottle code, and if the drum color code is not “1”, “011” is set as the bottle code (step) S37 to S39). Then, the derived bottle code (“100”, etc.) and the transferred drum code (1 or 2) are written in the drum side code storage means 31 (steps S40 and S41). This completes the identification code setting.
[0029]
As described above, when the model code is input, the main body side code storage means 13 of the printing press main body 1 stores a compatible drum code together with the model code, and when the type code of the ink itself is input, the drum side code storage of the drum unit 20 is stored. The means 31 stores the bottle code together with the drum code. In other words, the worker only inputs the model code and the color code of the ink to be used, and the model code is set in the printing machine main body 1 and the drum code and the bottle code are set in the drum unit 20. An identification code setting process for the main body 1 and the drum unit 20 can be performed by simple data input.
[0030]
In the production process, as described above, both the printer main body setting and the drum unit setting must be set as the identification code setting mode. However, when only the drum unit 20 is delivered, the printer main body setting on the printer main body 1 side is set. Since it has already been done, it is only necessary to set the drum unit. That is, the drum unit 20 is sold as an option such as color ink, and conventionally, it has been necessary to obtain the model information and ink information of the customer's printing machine main body 1 and set an identification means such as an ink bottle code. In the present invention, a drum color code as ink color information may be input.
[0031]
Next, the operation when the control means 21 on the drum unit 20 side is turned on will be described. The control means 21 on the drum unit 20 side is turned on when the power of the stencil printing apparatus is turned on or when the drum unit 20 detached from the printing press main body 1 is mounted again. When the control means 21 is turned on, as shown in FIG. 5, the control means (CPU) 21 is initialized, and the process proceeds to ink bottle information acquisition processing (steps S50 and S51).
[0032]
In the ink bottle information acquisition process, as shown in FIG. 6, the switch information is initialized to “000” (step S70), and the bottle set first switch 23, the bottle set second switch 24, and the bottle set third switch 25 are initialized. Each output is checked. If the bottle set first switch 23 is on, “100”, if the bottle set second switch 24 is on, “010”, if the bottle set third switch 25 is on, “001”. Are incremented to “000” in the switch information (steps S71 to S76).
[0033]
When the switch information, that is, the bottle code of the installed ink bottle (not shown) is thus obtained, the process returns to FIG. 5 and the bottle code and the bottle code stored in the drum-side code storage means 31 And confirming whether or not a suitable bottle is attached (step S55). This bottle confirmation information is transferred to the control means 3 on the printing press main body 1 side by communication processing, and when a suitable bottle is mounted, the processing proceeds to processing such as ink motor control (steps S56 and S57). If a suitable bottle is not attached, it is determined that the error is a bottle difference error, and for example, a process for displaying the fact on the display means of the operation panel 2 and displaying an appropriate type of ink bottle is performed.
[0034]
If the acquired bottle code remains “000”, it is determined that there is no bottle because the ink bottle is not installed, and for example, a message indicating that is displayed on the display means of the operation panel 2 and an appropriate ink bottle is displayed. Process to display the type.
[0035]
In this embodiment, when an incorrect ink bottle is attached, an error in the bottle difference occurs, so that the wrong ink bottle can be prevented from being attached. Also, when the ink bottle is not attached or when the wrong ink bottle is attached, the appropriate ink bottle type is displayed, so that the appropriate ink bottle can be easily attached.
[0036]
In this embodiment, the type code of the ink itself represents black ink and color ink. However, in other cases, for example, the ink material (ink characteristics) is different, and the ink material of the attached ink bottle is used. The present invention can be similarly applied to a case where printing control or the like corresponding to the printer is required.
[0037]
In addition, according to the said embodiment, although the stencil printing apparatus was demonstrated, of course, it is applicable to printing apparatuses other than a stencil.
[0038]
According to the embodiment, the ROM 12 and the main body side code storage means 13 as the main body side correspondence information memory, or the ROM 29 and the drum side code storage means 31 as the drum side correspondence information memory are separately provided. Although they are provided, they may be configured as the same storage means as long as they can hold information even when the power is turned off.
