[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-202864 Summary of the Invention [Problem to be solved by the invention]

[0004] Various errors can occur during the collating operation of a collating machine. For example, if a paper jam occurs, the user must remove the paper sheets that have become stuck in a paper feed shelf or the like. Even if an error occurs during the collating operation, the collating operation will usually continue until the current collating operation is completed. For this reason, depending on the nature of the error, it may be necessary to actually check the set of multiple paper sheets that may have an error. If the user can intuitively recognize the set of paper sheets that may have an error and the nature of the error, it is expected that the user's checking work will be completed quickly.

[0005] This embodiment has been made in consideration of the above circumstances, and aims to provide a collating machine that allows the user to intuitively recognize a set of paper sheets that may have an error and the content of the error. [Means for solving the problem]

[0006] In one embodiment, the collating machine is a machine that collates paper sheets fed from a paper feed shelf to generate a set of paper sheets, and when an error is detected, a plurality of error display areas whose display positions correspond to the set of paper sheets in which the error is detected are displayed on each of the paper feed shelves. Display position of The printer is provided with a control unit that displays on a display an error screen including a list of paper feed shelves that schematically shows the layout of the paper feed shelves and an error display that shows the content of the error in the form of a symbol or icon and that is displayed in the error display area of ​​the paper feed shelf that corresponds to the set of paper sheets in which the error has been detected. [Effects of the Invention]

[0007] According to this embodiment, it is possible to provide a collating machine that allows a user to intuitively recognize a set of paper sheets in which an error may have occurred and the details of the error. [Brief explanation of the drawings]

[0009] Hereinafter, an embodiment will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a collating machine according to one embodiment. The collating machine 1 in FIG. 1 includes a collating mechanism 10, a main control circuit 101, sub-control circuits 102, 103, 104, and 105, a display 106, operation switches 107, and a communication module 108. The collating machine 1 in FIG. 1 also includes a newspaper supply mechanism 30, an inserting and conveying mechanism 40, and a lifting mechanism 50 in addition to the collating mechanism 10. The newspaper supply mechanism 30 is a mechanism that inserts multiple stacked newspapers one by one into the inserting and conveying mechanism 40. The inserting and conveying mechanism 40 is a mechanism that folds a set of paper sheets collated by the collating mechanism 10 into newspapers inserted from the newspaper supply mechanism 30 and conveys the folded newspaper to the lifting mechanism 50. The lifting mechanism 50 is a mechanism that lifts and lowers the newspaper into which the set of paper sheets has been folded. Mechanisms other than the newspaper supply mechanism 30, the inserting and transport mechanism 40, and the lifting mechanism 50 may be used in combination with the collating machine 1.

[0010] The collating mechanism 10 has a plurality of paper feed shelves. The collating mechanism 10 is a mechanism that discharges a set of paper sheets, which is made by stacking paper sheets fed from the paper feed shelves, from an outlet. The paper sheets are, for example, inserts. The collating mechanism 10 may have any mechanism. For example, in the following description, the paper feed shelves are arranged vertically on both the front and back sides of the collating mechanism 10, but this is not limited to this.

[0011] The main control circuit 101 is a circuit serving as a control unit that controls the overall operation of the collating machine 1, including the control of the sub-control circuits 102, 103, 104, and 105. The main control circuit 101 is configured, for example, by a processor and a memory. The processor of the main control circuit 101 controls the operation of the collating machine 1 in accordance with a control application program stored in the memory. The processor is, for example, a CPU, but does not necessarily have to be configured as a CPU. The main control circuit 101 may also be configured as a hardware logic circuit such as an ASIC. The processor does not necessarily have to be configured as a single processor, but may be configured as multiple processors.

[0012] The sub-control circuit 102 is connected to the collating mechanism 10. The sub-control circuit 102 is a dedicated circuit that controls the operation of the collating mechanism 10 under the control of the main control circuit 101. The sub-control circuit 102 may or may not have a processor and memory separate from the main control circuit 101.

[0013] The sub-control circuit 103 is connected to the newspaper supply mechanism 30. The sub-control circuit 103 is a dedicated circuit that controls the operation of the newspaper supply mechanism 30 under the control of the main control circuit 101. The sub-control circuit 103 may or may not have a processor and memory separate from the main control circuit 101.

[0014] The sub-control circuit 104 is connected to the insertion and transport mechanism 40. The sub-control circuit 104 is a dedicated circuit that controls the operation of the insertion and transport mechanism 40 under the control of the main control circuit 101. The sub-control circuit 104 may or may not have a processor and memory separate from the main control circuit 101.

[0015] The sub-control circuit 105 is connected to the lifting mechanism 50. The sub-control circuit 105 is a dedicated circuit that controls the operation of the lifting mechanism 50 under the control of the main control circuit 101. The sub-control circuit 105 may or may not have a processor and memory separate from the main control circuit 101.

[0016] Here, the collating machine 1 may have sub-control circuits other than the sub-control circuits 102, 103, 104, and 105.

[0017] The display 106 is a display for displaying various states of the collating machine 1, such as an LED and a touch panel-type operation panel of the collating machine 1 provided on the collating mechanism 10. For example, the display 106 displays a counter screen that displays various collation counts. The collation count includes information such as the total number of sheets collated during the collation operation and the number of remaining sheets. The collation operation by the collating mechanism 10 is started while the counter screen is displayed. The display 106 also displays various setting screens. The various settings include settings for sheets by row, area settings, and entry / exit settings. The display 106 also displays an error screen for notifying various errors.

[0018] The operation switches 107 include various switches provided on the collating machine 1 and a touch panel-type operation panel of the collating machine 1 provided on the collating mechanism 10. For example, the operation switches 107 include a power switch for the collating machine 1. Furthermore, for example, the operation switches 107 include various mode switches. The operation switches 107 also include an error detection setting switch. The error detection setting determines whether or not an error corresponding to each switch is detected during the collating operation. When the error detection setting switch is set to a setting that detects errors, the corresponding error is detected, and when an error is detected, the collating operation is temporarily stopped upon completion of the collating operation currently being performed. On the other hand, when the error detection setting switch is set to a setting that does not detect errors, the corresponding error is not detected, and the collating operation continues even if an error occurs during the collating operation. The operation switches 107 may also include switches other than these switches. Furthermore, operations similar to those of the various switches of the operation switches 107 can also be performed on the operation panel.

[0019] The communication module 108 is a module including a processing circuit for communication with a terminal such as a smartphone and an external device such as a server of the collation machine 1. The communication module 108 is equipped with a wireless communication module required for wired and / or wireless communication.

[0020] The operation of the collating machine 1 will be described below. Figures 2 and 3 are diagrams showing an example of a counter screen displayed on the display 106, for example, on the operation panel of the collating machine 1. The counter screen is displayed, for example, under the control of the main control circuit 101 after the collating machine 1 is powered on. As described above, the user can start the collating operation of the collating mechanism 10 from the counter screen 200. Here, the counter screen may be displayed not on the operation panel of the collating machine 1, but on the display of a terminal such as a smartphone held by the user.

[0021] 2 shows a counter screen 200 in "tier display." The tier display is displayed when the tier display tab 201 is selected. When the tier display tab 201 is selected, the counter screen 200 displays a list of paper feed shelves 201a, front tier leaflet types 201b, back tier leaflet types 201c, and total leaflet types 201d. In addition, the counter screen 200 in "tier display" displays a setting and counter display area 203, a clear button 204, a zone mode button 205, a tapping switch 206, a tear detection switch 207, a count fold button 208, a start button 209, a user setting button 210, an error detection setting button 211, an individual tier setting button 212, an on / off setting button 213, an individual tier adjustment button 214, and a menu button 215.

[0022] The paper feed shelf list 201a is a list of paper feed shelves provided in the collating mechanism 10. FIG. 2 shows a list in the case where paper feed shelves are arranged vertically on both the front and rear sides of the collating mechanism 10. The row number assigned to each paper feed shelf is displayed on each paper feed shelf. The paper feed shelf at the bottom on the front side is assigned as a folding row, which is a paper feed shelf for inputting origami paper, and the character "fold" indicating that it is a folding row is displayed in the list. Although not shown in FIG. 2, for paper feed shelves in the paper feed shelf list 201a that are set for insert flyers, the name of the corresponding insert flyer is displayed.

[0023] The first row leaflet type 201b is a display field for the number of types of insert leaflets set in the first row, which is the paper feed shelf on the front side of the collating mechanism 10. In FIG. 2, since no insert leaflets are set in any of the first row leaflet feed shelves 1-11, an example is shown in which the first row leaflet type 201b displays "0." The second row leaflet type 201c is a display field for the number of types of insert leaflets set in the second row, which is the paper feed shelf on the back side of the collating mechanism 10. Since no insert leaflets are set in any of the second row leaflet feed shelves 12-22, an example is shown in which the second row leaflet type 201c displays "0." The total number of leaflets 201d is a display field for the total number of types of insert leaflets in the first row and the second row combined. In FIG. 2, since no insert leaflets are set in either the first or second row leaflet feed shelves, the total number of leaflet types 201d also displays "0."

[0024] 3 shows the counter screen 200 for "area display." The area display is displayed when the area display tab 202 is selected. When the area display tab 202 is selected, the area name 202a, the number of settings 202b, and the status 202c are displayed. In addition, the counter screen 200 for "area display" displays the same settings and counter display area 203, the clear button 204, the area mode button 205, the tapping switch 206, the tear detection switch 207, the count folding button 208, the start button 209, the user setting button 210, the error detection setting button 211, the individual row setting button 212, the start / stop setting button 213, the individual row adjustment button 214, and the menu button 215 as in the counter screen 200 for "row display."

[0025] Area name 202a is a list of area names set on the setting screen for each tier. Number of settings 202b is the number of sets of paper sheets for which the collation operation for the corresponding area name will be stopped. Status 202c is a section that displays the completion status of the collation operation for the corresponding area name. Status 202c can display one of three statuses, for example, "Completed," "Folding," and "Incomplete." "Completed" means that the collation operation for the corresponding area name has been completed. "Folding" means that the collation operation for the corresponding area name is currently being performed. "Incomplete" means that the collation operation for the corresponding area name has not yet been performed.

[0026] The setting and counter display area 203 is a display area for various settings and counters related to the collation operation. In Figures 2 and 3, the setting and counter display area 203 has display columns for the total number, the number of executions, the number of settings, the planned total number, the remaining number, the area name, the planned number of stops, and the count number.

[0027] The total number is a display column for the total number of sets of paper sheets that have been collated so far. The run number is a display column for the number of sets of paper sheets that have been collated in the current collation operation. When the zone mode is enabled, the run number displays the run number for each zone. The set number is a display column for the number of sets of paper sheets that will cause the current collation operation to be stopped. When the zone mode is enabled, the set number displays the set number for each zone. When the run number reaches the set number, the collation operation is temporarily stopped. The planned total number is a display column for the total number of sets of paper sheets that are planned to be collated until the collation operation is completed. For example, when the zone mode is enabled, the planned total number may display the sum of the set numbers for each zone. The remaining number is a display column for the remaining number of sets of paper sheets to be collated in the current collation operation. The zone name is a display column for the name of the zone that is the target of the current collation operation when the zone mode is enabled. The planned stop number is a display column for the number of sets of paper sheets that will cause the current collation operation to be stopped. The count number is a display column for displaying the count of the count inserts.

[0028] The clear button 204 is a button that is selected when clearing the total number and the execution number. When the clear button 204 is selected, the values ​​of the total number and the execution number are cleared to zero.

[0029] The area mode button 205 is a button that is selected when switching between normal mode and area mode in the display of the setting and counter display area 203. When the area mode button 205 is selected and the display is switched to area mode, the display of the area name in the setting and counter display area 203 becomes enabled.

[0030] The tapping switch 206 is a switch that switches on and off the operation of the tapping mechanism for aligning paper sheets during the collating operation, and is provided in the collating mechanism 10. When the tapping switch 206 is on, the paper alignment function during the collating operation is enabled, and when the tapping switch 206 is off, the paper alignment function during the collating operation is disabled.

[0031] The tear detection switch 207 is a switch that switches on and off the operation of detecting paper tears during the collating operation. When the tear detection switch 207 is on, the paper tear detection operation during the collating operation is enabled, and when the tear detection switch 207 is off, the paper tear detection operation during the collating operation is disabled. When the paper tear detection operation is disabled, the collating operation continues even if a paper tear occurs during the collating operation.

[0032] The count fold button 208 is a button that is selected when setting the count fold. When the count fold button 208 is selected, a dialog box for inputting the count value for the count fold is displayed.

[0033] The start button 209 is a button that is selected when starting the collating operation. When the start button 209 is selected, the collating operation starts.

[0034] The user setting button 210 is a button selected when displaying a user setting screen for making various user settings such as the setting of the buzzer sound when an error is detected. The user can make various user settings on the user setting screen.

[0035] The error detection setting button 211 is a button that is selected when displaying an error detection setting screen for enabling / disabling error detection during the collating operation, such as double feed, paper jam, out of paper, and paper delay. Errors for which error detection is disabled will not be detected during the collating operation. Therefore, even if an error occurs, the collating operation continues. In other words, the error detection setting button 211 is a button for performing settings equivalent to those of the error detection setting switch of the operation switches 107, using the touch panel.

[0036] The shelf setting button 212 is a button that is selected when displaying a shelf setting screen for configuring settings for each paper feed shelf. On the shelf setting screen, the user can configure settings such as zone settings and input / output settings for each paper feed shelf.

[0037] The inlet / outlet setting button 213 is a button selected when displaying an inlet / outlet setting screen for setting the inlet / outlet setting. On the inlet / outlet setting screen, for example, it is possible to switch whether to use the inlet / outlet function or not, and whether to perform the inlet / outlet setting based on the paper feed shelf or the flyer.

[0038] The each shelf adjustment button 214 is a button that is selected when displaying an each shelf adjustment screen for making detailed adjustments for each paper feed shelf. On the each shelf adjustment screen, the user can set flyers for each paper feed shelf, adjust the paper alignment function, enable / disable multi-feed detection, set the paper size, etc.

[0039] The menu button 215 is a button that is selected when displaying a menu screen for various detailed settings of the collating machine other than user settings, error detection settings, each stage settings, start / stop settings, and each stage adjustment.

[0040] Fig. 4 is a diagram showing an example of an error screen in an embodiment. If an error is detected during the collating operation, the main control circuit 101 completes the currently executing collating operation, then stops the collating operation, and displays the error screen shown in Fig. 4 on, for example, the display 106. The error screen may be displayed not on the operation panel of the collating machine 1, but on the display of a terminal such as a smartphone held by the user.

[0041] An example of the error screen 300 includes a list of paper feed shelves 301. The list of paper feed shelves 301 schematically shows the arrangement of paper feed shelves provided in the collating mechanism 10. A row number 301a is displayed on each paper feed shelf. Among the row numbers 301a, the row number 301a of the paper feed shelf associated with the insert leaflet is highlighted, for example, by being colored.

[0042] Furthermore, in this embodiment, four error display areas 301b1, 301b2, 301b3, and 301b4 are set at the positions of the respective paper feed shelves in the paper feed shelf list 301. An icon representing an error detected when collating paper sheets from the corresponding paper feed shelf is displayed in the error display areas 301b1, 301b2, 301b3, and 301b4. Each of the error display areas 301b1, 301b2, 301b3, and 301b4 is associated with the number of sets of paper sheets for which an error may be detected from the time an error is detected during the collating operation until the collating operation is stopped. Specifically, the error display area 301b1 is a display area for displaying an error detected in the set of paper sheets at the time the error was detected. Similarly, error display area 301b2 is a display area for displaying an error detected in the second set of paper sheets from the time the error was detected, error display area 301b3 is a display area for displaying an error detected in the third set of paper sheets from the time the error was detected, and error display area 301b4 is a display area for displaying an error detected in the fourth set of paper sheets from the time the error was detected.

[0043] In FIG. 4, the error display area 301b1 for the "fold" folding step displays a "break" symbol, the error display area 301b2 for the "fold" displays a "missing" symbol, the error display area 301b3 for the "fold" displays an "abnormal" symbol, and the error display area 301b4 for the "fold" displays an "no" symbol. The "break" symbol indicates that a paper tear error was detected when feeding paper from the corresponding paper feed shelf during the collating operation for the paper sheets corresponding to the position of the error display area. The "missing" symbol indicates that a paper missing error was detected when feeding paper from the paper feed shelf. The "abnormal" symbol indicates that a paper feeding error was detected when feeding paper from the paper feed shelf. The "no" symbol indicates that an out-of-paper error was detected when feeding paper from the paper feed shelf.

[0044] That is, the display of the "Broken" symbol in the "Fold" error display area 301b1 indicates that a tear has occurred in the first set of origami paper since the time the error was detected. The display of the "Missing" symbol in the "Fold" error display area 301b2 indicates that a missing piece of origami paper has been left out from the second set of origami paper since the time the error was detected. The display of the "Abnormal" symbol in the "Fold" error display area 301b3 indicates that an abnormality has been detected in the feeding of origami paper from the folding step during the collating operation for the third set since the time the error was detected. The display of the "No" symbol in the "Fold" error display area 301b4 indicates that no paper has been detected in the folding step during the collating operation for the fourth set since the time the error was detected.

[0045] Similarly, the "late" symbol is displayed in the error display area 301b2 in the first row. Furthermore, the "jam" symbol is displayed in the error display area 301b3 in the third row and the error display area 301b3 in the twentieth row. Furthermore, the "heavy" symbol is displayed in the error display area 301b2 in the sixth row. Furthermore, the "no" symbol is displayed in the error display area 301b2 in the thirteenth row. The "late" symbol indicates that a paper missing error has been detected when feeding paper from the paper feed shelf. The "jam" symbol indicates that a paper jam error has been detected when feeding paper from the paper feed shelf. The "heavy" symbol indicates that a double feed error has been detected when feeding paper from the paper feed shelf.

[0046] That is, the display of the "delay" symbol in the error display area 301b2 for "1" indicates that a delay occurred in the feeding of paper sheets from the first paper feed shelf during the collating operation for the second set after the error was detected. The display of the "jam" symbol in the error display area 301b3 for "3" and "20" indicates that a paper jam was detected in the third and twentieth paper feed shelves during the collating operation for the third set after the error was detected. The display of the "heavy" symbol in the error display area 301b2 for "6" indicates that two overlapping sheets were fed from the sixth paper feed shelf during the collating operation for the second set after the error was detected. The display of the "no" icon in the error display area 301b2 for "13" indicates that no paper was detected in the thirteenth paper feed shelf during the collating operation for the second set after the error was detected.

[0047] Furthermore, confirmation required display 301c for displaying the number of sets of paper sheets that the user needs to check is displayed in paper feed shelf list 301. In the example of Fig. 4, some kind of error has been detected in all of the first, second, third, and fourth sets, so confirmation required display 301c displays a message that four sets need to be checked.

[0048] In this embodiment, a symbol indicating the content of the error is displayed in error display areas 301b1, 301b2, 301b3, and 301b4 provided for each paper feed shelf. The display of the paper feed shelf list 301 allows the user to intuitively check which set of paper sheets should be checked for which error.

[0049] Here, the symbols shown in FIG. 4 are just an example. Symbols corresponding to other errors may be added, and the display mode of the symbols may be changed as appropriate. Also, instead of symbols, icons including pictures that schematically represent the content of the error may be displayed. Furthermore, icons consisting of a combination of characters and pictures may be displayed.

[0050] Furthermore, the error screen 300, as an example, may have a detailed error display area 302. The detailed error display area 302 is a display area for displaying in text the same detailed content as the error display in the paper feed shelf list 301. The detailed error display area 302 displays a list including the paper feed shelf in which the error was detected and the content of the error for each set of paper sheets in which an error was detected. Errors that cannot be displayed in the detailed error display area 302 can be scrolled by selecting a scroll bar 302a.

[0051] 4 is an example. For example, the detailed error display area 302 may also display information that cannot be displayed in the paper feed shelf list 301, such as a brief explanation of the error content.

[0052] Furthermore, the example error screen 300 may have error display areas for each of the newspaper supply mechanism 30, the inserting and conveying mechanism 40, and the lifting mechanism 50. The error screen 300 in FIG. 4 has an error display area 303 for the lifting mechanism 50 and an error display area 304 for the inserting and conveying mechanism 40. In the error display area 303, if an error occurs in the lifting mechanism 50, a message indicating the content of the error is displayed. FIG. 4 shows an example in which a message indicating that the lifting mechanism 50 is fully loaded is displayed. In addition, in the error display area 304, if an error occurs in the inserting and conveying mechanism 40, a message indicating the content of the error is displayed. FIG. 4 shows an example in which a message indicating that a conveyance abnormality has occurred during the conveyance of a set of paper sheets is displayed.

[0053] Furthermore, the example error screen 300 may have a setting and counter display area 305. In Fig. 4, the setting and counter display area 305 is shown to have a total number, execution number, setting number, and area name. The display in the setting and counter display area 305 allows the user to understand the progress of the collation operation at the time the error was detected.

[0054] Furthermore, the error screen 300, as an example, may have a confirmation button 306. The confirmation button 306 is a button for detecting that the user has confirmed the error. When the confirmation button 306 is selected, the main control circuit 101 transitions the error screen 300 to the counter screen 200. When the confirmation button 306 is selected, the main control circuit 101 may perform error detection again, and when it is confirmed that the error has been resolved, transition the error screen 300 to the counter screen 200.

[0055] Furthermore, the error screen 300, as an example, may have a start button 307 as a button for starting the collating operation. The start button 307 is a button for skipping the error confirmation and immediately continuing the collating operation. When the start button 307 is selected, the main control circuit 101 transitions the error screen 300 to the counter screen 200, and further resumes the collating operation as if the start button 209 had been selected on the counter screen 200.

[0056] As described above, according to the embodiment, when an error is detected during a collating operation by the collation machine 1, a symbol or icon is displayed as an error display indicating the content of the error in the error display area of ​​the paper feed shelf corresponding to the set of paper sheets in which the error was detected in the paper feed shelf list 301, in which multiple error display areas whose display positions correspond to the set of paper sheets in which the error was detected are assigned to each paper feed shelf. Such an error screen allows the user to intuitively confirm the set of paper sheets that requires error confirmation and the content of the error.

[0057] (Variation) A modified example of the embodiment will be described below. Fig. 5 is a diagram showing an error screen of the modified example of the embodiment. Fig. 5 shows an example in which nothing is displayed in the error display area 303 of the lifting mechanism 50 and the error display area 304 of the insertion and transport mechanism 40. This indicates that no errors have been detected in the lifting mechanism 50 or the insertion and transport mechanism 40.

[0058] As described above, the error screen 300 may be provided with a start button 307. The start button 307 may be provided to immediately resume the collating operation without having to check for an error. However, if the collating operation is resumed without resolving an error such as a paper jam, there is a possibility that a further error may occur.

[0059] Therefore, for example, the error protection mode may be configured to be enabled / disabled on an error detection setting screen accessible from the error detection setting button 211. When the error protection mode is set to disabled, the main control circuit 101 displays the start button 307 as in FIG. 4. On the other hand, when the error protection mode is set to enabled, the main control circuit 101 does not display the start button 307 as shown in FIG. 5. In this case, the user can resume the collation operation only after selecting the confirmation button 306 on the error screen 300 and then selecting the start button 209 on the counter screen 200. By prompting the user to confirm the error in this way, the collation operation is prevented from being resumed while an error has been detected.
