An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic external view of a printing system corresponding to the first embodiment of the image forming system.

The printing system 1 has a structure in which the printing server 2 and the output device 3 are connected by a cable in appearance.

The print server 2 has a user display unit 10 and a main body unit 20. The user display unit 10 is responsible for displaying information to the user of the printing system 1, and also accepts operations by the user via, for example, a touch panel type display screen. The main body 20 includes a CPU, a storage device, and the like, and is responsible for controlling the printing system 1.

The output device 3 includes a printing machine 30 as a main body, and a folding machine 40 and a folding machine 50 connected to the printing machine 10 as a post-processing machine (finisher).

The printing machine 30 forms and sends an image on paper as a kind of recording material by, for example, an electrophotographic method or an inkjet method. In the present embodiment, it is assumed that the printing machine 30 is provided with a device capable of printing on one side of the recording material and printing on both sides. This printing machine 30 corresponds to an example of the image forming machine referred to in the present invention.

The fold line machine 40 opens the paper sent from the printing machine 30 with creases, and sends out the opened paper. The device provided as the crease machine 40 in the output device 3 may have a function of a top-bottom cutting process for cutting the top and bottom of the paper, in addition to the crease process for making creases on the paper. The folding line machine 40 corresponds to an example of the folding line machine according to the present invention.

The folding machine 50 folds the paper sent from the folding machine 40 and sends out the folded paper. The device provided as the folding machine 50 in the output device 3 may have a staple processing or punching function in addition to the paper folding process. The folding machine 50 corresponds to an example of the folding machine referred to in the present invention.

When both the folding machine 40 and the folding machine 50 are connected as a finisher, the folding line processing by the folding machine 40 and the paper folding process by the folding machine 50 can be performed independently or on the same paper. Overlapping implementation of the above may also be selected. When the crease processing and the paper folding process are performed in combination, the fold line processing needs to be performed before the paper folding process, so that the fold line machine 40 folds with the printing machine 30. It is connected to the machine 50.

FIG. 2 is a schematic functional configuration diagram of the printing system shown in FIG.

When viewed as a functional configuration, the printing system 1 includes a printing server 2 and an output device 3, and the output device includes a printing machine 30, a folding line machine 40, and a folding machine 50.

The print server 2 includes the user display unit 10 described above, and the job management unit 21 and the print control unit 22 are incorporated in the main body unit 20 described above. The job management unit 21 is connected to an external device 5 represented by a personal computer or the like via a communication network such as a LAN, and receives and manages job data including image data representing an image to be printed. Is. The print control unit 22 sets print information indicating the number of copies to be printed, the type of paper, and the like via the user display unit 10, and sends the print information together with the job data to the output device 3 to execute printing. .. When the output device 3 includes a post-processing machine, the setting of the post-processing machine is also included in the print information. When the folding machine 40 and the folding machine 50 are provided as the post-processing machine as in the present embodiment, the orientation, the number, the position, and the like are set for the folding lines and the paper folding. The specific setting method will be described in detail later.

The printing machine 30 of the output device 3 incorporates a control unit 31 and a printing unit 32. The printing unit 32 is a mechanical mechanism that executes image formation, and the control unit 31 describes the mechanical operation of the output device 3 including the folding machine 40 and the folding machine 50, which are post-processing machines, with the above-mentioned printing information. It is controlled according to. Further, the control unit 31 also has a role of obtaining device information such as a model from the folding machine 40 and the folding machine 50 and notifying the device information to the print control unit 22 of the print server 2.

Paper that has been creases by the crease machine 40 is generally a product of being folded in the opposite direction to the creases of the creases, for example, if the creases are valley folds, the paper. The fold is a mountain fold. When the fold lines and the paper folds are oriented in opposite directions in this way, high-strength paper folds are realized. Such a folding machine 40 is a device that has recently appeared as compared with the folding machine 50, and there are cases where it is assumed that the paper folding for finally obtaining the deliverable is performed manually. There are many. When the paper fold is performed by hand, the position of the paper fold is finely adjusted according to the position of the fold line, so that the position is less likely to shift.

On the other hand, there are a plurality of models of the folding machine 50, and there is also a folding machine 50 in which the fine adjustment is not taken into consideration at the time of design because the existence of the folding line machine 40 is not premised. Therefore, depending on the model of the folding machine 50, when the paper with creases is folded, the crease position and the paper folding position may be misaligned. If such a misalignment occurs, not only does it look bad, but the paper is also severely damaged. Therefore, in the present embodiment, control is performed to avoid the occurrence of misalignment and to avoid deterioration of the appearance and damage of the paper.

The setting and control of creases and paper folds will be described in detail below.

FIG. 3 is a diagram showing a job management screen.

When one job 103 is selected on the job management screen 101 and the property display is instructed, the property screen pops up.

FIG. 4 is a diagram showing a state in which the first tab including the paper folding setting is selected on the job property screen.

The property screen 105 is provided with three tabs 106, 107, and 108, and FIG. 4 shows a state in which the first tab 106 is selected. In the first tab 106, the folding machine 50 is set. Specifically, the staple setting field 111 in which the staple processing content is set, the punch setting field 112 in which the punch processing content is set, and the paper folding process. The paper folding setting field 113 in which the contents of the above are set is provided. In addition, a preview column 120 for displaying an image of processing according to the set contents is also provided.

For these setting fields, setting control that reflects the device information obtained from the folding machine 50 is performed via the control unit 31 of the printing machine 30. For example, for the folding machine 50 having no staple function and the folding machine 50 having no punch function, the set values in the staple setting field 111 and the punch setting field 112 are fixed to "No". With respect to the folding machine 50 having the staple function and the folding machine 50 having the punch function, the staple setting field 111 and the punch setting field 112 are in a state in which "no" or "yes" can be selected as the setting values.

The paper folding setting field 113 is provided with a type setting field 114 and a number of sheets setting field 115. In the number of sheets setting field 115, the number of sheets to be folded as a bundle at one time is within a range of up to 15 sheets. It is set selectively. In the type setting field 114, the paper folding type is selectively set by the pull-down menu.

FIG. 5 is a diagram showing a menu for selecting a type of paper folding.

In the pull-down menu 116 of the type setting field 114, as the types of paper folds, for example, two folds that fold the paper in two at one fold line, Z folds that fold each of the two fold lines in opposite directions, and two folds. Inside each fold line, there are three folds that fold in the same direction. Further, in the pull-down menu 116, not only the type of paper folding but also the menu items showing the settings including the orientation of the paper folding are lined up. For example, the menu item "folded in half (printed inside)" is printed. If the surface is the upper surface, it means folding in a valley fold with the printed surface inside.

By selecting a menu item from such a pull-down menu 116, instructions on the type and orientation of paper folding for the folding machine 50 are set.

Next, the setting on the second tab 107 of the property screen 105 will be described.

FIG. 6 is a diagram showing a state in which the second tab is selected on the property screen.

On the second tab 107 of the property screen 105, the crease machine 40 is set, and specifically, the crease (crease) is set and the top and bottom cutting is set. The second tab 107 of the property screen 105 is provided with a setting content display field 121, an edit button 122, and a preview field 123.

In the setting content display field 121, the setting contents of the crease (crease) and the top and bottom cutting are described in characters, and in the preview field 123, an image of the process according to the setting contents is displayed.

When the edit button 122 is selected, a setting screen for editing those settings is displayed in a pop-up.

FIG. 7 is a diagram showing a crease setting screen.

This setting screen 125 is a screen that can be switched to the top / bottom cutting setting screen by selecting tab 126. However, in the following, it is described that the creases (creases) are set on this setting screen 125, and the top / bottom cutting is performed. The description of the setting of is omitted.

The setting screen 125 is provided with a check box 131, a type setting field 132, a direction setting field 133, a custom setting field 134, and a preview field 140.

When the check box 131 is checked, it is set that the crease machine 40 executes the crease processing, and when the check box 131 is unchecked, the crease processing is not performed. ..

In the type setting field 132, the type of crease is set by the pull-down menu. As for the types of folds, the same folds as the above-mentioned folds, such as bi-fold, Z-fold, and inner tri-fold, are lined up in the menu, and further, outer tri-fold, Kannon fold, rolled quartet, bellows fold, etc. line up. In the folding machine 40, since the folding lines are formed one by one and the folding lines are not bent, the degree of freedom of the folding lines is higher than that of the folding machine 50, and "custom" is also selected as the type of the folding lines.

In the direction setting field 133, the direction (direction) of the crease is set. However, for example, in the case of the setting of "inside printing", when the printing surface is the upper surface, the fold line means a mountain fold instead of a valley fold. This follows the expression that is popular in the printing field and the like because strong folding is realized by folding the paper in the opposite direction to the crease in the case of hand folding.

The custom setting field 134 becomes active when "custom" is selected in the type setting field 132. The custom setting field 134 is provided with a number setting field 135, a folding method setting field 136, a strength setting field 137, and a position setting field 138.

In the number setting field 135, a maximum of 5 lines are set, and the number of sets of the folding method setting field 136, the strength setting field 137, and the position setting field 138 is set in the custom setting field 134 by the same number as the number set here. Is displayed.

In the folding method setting field 136, either "mountain fold" or "valley fold" is selected and set for each fold line. In the strength setting field 137, the strength at which the creases are formed is set, and in the position setting field 138, the position of each crease is set by the distance from the base point.

In the preview column 140, an image of processing according to the setting contents of the creases is displayed.

The creases and paper folds are set by each of the screens described above, but in the present embodiment, the prohibition processing described below is executed at the time of setting. In this prohibition processing, as for the combination of the direction of the fold line and the direction of the paper fold, only the combination of strengthening the fold is permitted as described above. That is, only combinations in which the directions of the fold lines and the paper folds are opposite to each other are allowed, and combinations in which the directions of the fold lines and the paper folds are the same are rejected. Further, since the degree of freedom of the folding machine 50 is lower than the degree of freedom of the folding machine 40, only the setting of folding in half is permitted when both the folding line processing and the paper folding processing are performed on the same paper. Is to be done.

When the user selects a setting contrary to these prohibition processing, a confirmation screen is displayed, and the setting according to the prohibition processing is required.

FIG. 8 is a diagram showing a first example of the confirmation screen.

The confirmation screen 141 of the first example is a screen displayed when "Z fold (right binding / bottom binding)" is set as the paper folding process and then execution of the crease processing is selected. In this case, the execution of the crease processing selected later is prioritized, and in combination with the selection, it is proposed to change the setting to "No" as the setting of the paper fold processing permitted by the prohibition processing.

The confirmation screen 141 is provided with a yes button 142 and a no button 143, and the paper folding setting is changed to "no" as suggested when the yes button 142 is selected, and the no button 143 is selected. When this is done, the execution of the crease processing that was set immediately before is canceled, and the screen returns to the crease processing setting screen.

FIG. 9 is a diagram showing a second example of the confirmation screen.

The confirmation screen 145 of this second example is when "fold in half" and "print inside" are selected as the setting of the crease processing, and then "fold in half (print on the outside)" is selected as the paper folding process. This is the screen that is displayed. In this case as well, the paper folding process of "folding in half (printing on the outside)", which is a setting item selected later, is prioritized, and as a combination with that setting, "outside" is set as the setting of the crease processing permitted by the prohibition processing. A change to "print" is proposed.

The confirmation screen 145 of the second example is also provided with a yes button 146 and a no button 147, and the crease processing setting is changed to "outside printing" as suggested when the yes button 146 is selected. When the No button 147 is selected, the paper folding process of "folding in half (printed on the outside)" selected immediately before is canceled, and the screen returns to the setting screen of the paper folding process.

After the setting of the combination restricted by such prohibition processing is accepted by the print control unit 22 as the setting of the crease processing and the paper folding processing via the user display unit 10, in the present embodiment, the print control unit 22 , The direction control of the folding line and the paper folding is executed according to the capabilities of the folding line machine 40 and the folding machine 50 incorporated in the output device 3.

FIG. 10 is a flowchart showing the direction control of creases and paper folds in the print control unit.

The print control unit 22 acquires the crease and paper fold setting information set on the above-mentioned setting screen via the user display unit 10 (step S101). Further, the print control unit 22 acquires the device information of the folding machine 40 and the folding machine 50 via the control unit 31 of the printing machine 30. In the present embodiment, it is assumed that the device information also includes information (config information) indicating the performance of the folding machine 40 and the folding machine 50 (step S102).

When the device information does not include the performance, the print control unit 22 or the control unit 31 of the printing machine 30 has a correspondence table in which the model and the performance are associated in advance, and the correspondence table and the device are provided. Performance may be recognized by collating with the model included in the information. Further, as for the performance of the device, it is not always necessary to recognize both the folding machine 40 and the folding machine 50, and at least the folding machine 50 may be recognized.

Next, it is determined based on the config information whether or not the creases and the paper folds in opposite directions can be processed. In other words, it is determined whether or not the folding machine 50 as a combination with the folding line machine 40 is a device corresponding to the paper folding process in the direction opposite to the folding line (step S103).

If it is determined in this determination that the folding machine 50 is a first-class folding machine that does not support the reverse paper folding process (step S103: No), the folding streaks are aligned with the direction of the paper folding process. The direction of processing is specified. As described above, since the folding machine 50 has a lower degree of freedom than the folding machine 40, an appropriate combination can be obtained by giving priority to the direction of the paper folding process and determining the direction of the folding line processing. .. That is, the direction of the paper fold in the folding machine 50 is confirmed in the config information (step S104), and if the direction of the paper fold is a mountain fold, the direction of the fold line is also specified as a mountain fold (step S105), and the direction of the paper fold. If is a valley fold, the direction of the crease is also specified as a valley fold (step S106). Therefore, when the folding machine 50 is a first-class folding machine, a combination of paper folding and folding lines in a direction contrary to the prohibition processing in the setting via the user display unit 10 is executed as a result. Regarding the printing surface, it is assumed that the printing surface as set is realized by printing with the printing machine 30 on the side corresponding to the set "inside printing" or the like.

Here, as the first-class folding machine, for example, a folding machine having low performance is assumed in which the folding position may deviate from the position of the folding line when folding in the direction opposite to the direction of the folding line. To. However, the "low performance" here does not necessarily mean the performance of the folding process itself. For example, if there are no creases, the folding position is always an accurate folding machine, but since fold processing is not assumed for paper with creases, the paper with creases is oriented in the opposite direction to the direction of the creases. Folding machines whose folding positions are displaced due to the fold lines when folding are also treated here as "low performance" type 1 folding machines.

In such a first-class folding machine, in order to avoid unsightly appearance and damage to the paper due to the folding position being displaced, folding lines and paper folding in the same direction are executed even in violation of the above prohibition processing. In addition, since the above prohibition processing is executed at the time of setting and the instruction is changed after that, the user does not feel uncomfortable at the time of setting, and the instruction conforms to the performance of the folding machine 50 or the like. It will be an instruction.

When it is determined in the determination of step S103 described above that the folding machine 50 is a type 2 folding machine corresponding to the reverse paper folding process (step S103: Yes), the direction of the crease processing is It is specified in the opposite direction to the paper folding process. That is, the direction of the paper folding in the folding machine 50 is confirmed in the config information (step S107), and if the direction of the paper folding is a mountain fold, the direction of the fold line is specified as a valley fold (step S108), and the direction of the paper folding. If is a valley fold, the direction of the fold line is specified as a mountain fold (step S109). When the folding machine 50 is a type 2 folding machine, a combination of paper folding and creases according to the above-mentioned prohibition processing is realized. Further, as for the printing surface, the printing on the side according to the setting is performed by the printing machine 30, so that the printing surface as set is realized.
