TECHNICAL FIELD

[0001] The present application relates to a paper conveying device that conveys paper discharged from an upstream-side paper handling device to a downstream-side paper handling device, and particularly relates to a conveying control device and a conveying control method that control a paper conveying timing. BACKGROUND

[0002] Conventionally, a paper conveying device is known that stacks paper discharged from a printer in a bundle and then conveys the stacked paper bundle. For example, a paper conveying device is disclosed in Japanese Patent Laid-Open No. 2001-019261 that has a paper stacking section that temporarily stacks paper discharged from a printer, and when the paper stacking section has stacked a certain number of sheets of paper to form a paper bundle, a timing belt is driven to discharge the paper bundle from the discharge section and convey it to a stapler for subsequent processing. SUMMARY

[0003] Problem to be Solved by the Invention

[0004] The paper conveying device described in Japanese Patent Laid-Open No. 2001-019261 conveys a paper bundle to a stapler at a timing at which a certain number of sheets of paper discharged from a printer have been stacked. Therefore, the conveying timing depends on the printing speed of the printer, and it is necessary to adjust the timing of the processing at the stapler side. Also, because the processing speed at the stapler side depends on the printing speed of the printer, it is difficult to improve efficiency.

[0005] The present application was developed in view of this situation, and aims to provide a conveying control device and a conveying control method that can perform paper conveying at an appropriate timing in accordance with the processing cycle of a downstream-side paper handling device.

[0008] The third embodiment of the present application is a non-transitory computer-readable recording medium which records a program for causing a computer to function as the above-described conveyance control device.

[0009] The fourth embodiment of the present application is a paper processing device which is supplied with paper by a paper conveyance device, and which has the above-described conveyance control device.

[0023] Hereinafter, an embodiment of a conveying control device and a conveying control method according to the present application will be described with reference to the accompanying drawings.

[0024] Figure 1 is a functional block diagram showing an overall schematic configuration of a paper processing system 10 according to an embodiment of the present application. As shown in Figure 1 , the paper processing system 10 is provided with a paper conveying device 100, an upstream-side paper processing device (first paper processing device) 101, and a downstream-side paper processing device (second paper processing device) 102. As will be described later Figure 2 , the paper conveying device 100 is connected to the paper processing device 101 and the paper processing device 102, for example.

[0025] The paper processing device 101 performs a specific processing on a paper and discharges the processed paper to the paper conveying device 100. As an example of the paper processing device 101, a printing machine, a paper unwinding device provided with a cutting machine, or the like can be cited.

[0026] The paper conveying device 100 temporarily stacks the paper discharged from the paper handling device 101, and then supplies the stacked paper one by one or in a specific number of sheets to the downstream-side paper handling device 102. The paper handling device 102 receives the supply of paper from the paper conveying device 100, performs a specific processing on the paper, and discharges the processed paper. As an example of the paper handling device 102, a rotary die cutter, a saddle stitcher, a cutting device, and the like can be cited. For example, the paper handling device 102 is a device that continuously performs processing in a specific cycle (period).

[0027] For example, the paper conveying device 100 is provided with the control device 50, the paper handling device 101 is provided with the control device 60, and the paper handling device 102 is provided with the control device 70.

[0028] The control devices 50, 60, and 70 can be configured to be connected to each other via a general-purpose communication network, and can transmit and receive information to and from each other. In addition, the communication connection form and the communication protocol are not particularly limited. That is, in the present embodiment, it is sufficient that at least the control device 60 and the control device 70 can implement a series of processes described later.

[0029] The control device 70 of the paper handling device 102 is provided with, for example, a conveying control section 71, a sheet feeding control section 72, a processing control section 73, and the like. Details of each of these control sections will be described later.

[0030] In the present embodiment, as an example, a case where the control device 70 of the paper handling device 102 is mounted with the conveying control section 71 is exemplified, but is not limited to this example. For example, the conveying control section 71 can be independently provided as a separate control device, can be mounted in an upper device such as the control device 70, or can be mounted in the control device 50. That is, as a whole, the paper handling system 10 has the function of the conveying control section 71, and the specific device that implements this function is not particularly limited. For example, the control device 70 can have part of the function of the conveying control section 71, or the control device 50 can have part of the function of the conveying control section 71. Details of various processes performed by the conveying control section 71 and the like will be described later.

[0031] In addition, the paper handling system 10 does not necessarily need to have the upstream-side paper handling device 101. For example, it can be configured such that a robot or a person such as an automatic transport vehicle sets the paper processed by the upstream-side paper handling device 101 to the paper stacking area 15 of the paper conveying device 100 (see FIG. 1) (refer to FIG. 2). Figure 2 )。

[0032] Figure 2 is a drawing showing a schematic side view of the paper conveying device 100 and the paper handling device 102, Figure 3is a view showing a schematic plan view of the paper conveying device 100. In Figure 2 , as an example of the paper processing device 102, a case where a rotary die cutter is applied is illustrated. However, as described above, the paper processing device 102 is not limited to the rotary die cutter.

[0033] Also, the configuration of the paper conveying device 100 and the paper processing device 102 described below is only an example and is not limited to this example. For example, an alternative configuration can be adopted, or part of the configuration can be changed or omitted.

[0034] As shown in Figure 2 , Figure 3 , the paper conveying device 100 is provided with a first conveying section 5. The first conveying section 5 conveys paper stacked in a paper stacking region 15 to the paper processing device 102. The first conveying section 5 is provided with, for example, a suction-type conveying belt (hereinafter, simply referred to as "conveying belt"). As shown in Figure 3 , the conveying belt is provided with, for example, a driving roller 1, an idler roller 2, a plurality of endless conveying belts 3 arranged between the driving roller 1 and the idler roller 2, and a conveying drive section 4, and the like.

[0035] The driving roller 1 is provided with, for example, a rotation shaft and four first pulleys (not shown) arranged at intervals from each other in the axial direction of the rotation shaft. The first pulleys are rotatably integrated with the rotation shaft.

[0036] The idler roller 2 is provided with, for example, a shaft parallel to the rotation shaft of the driving roller 1, and four second pulleys (not shown) freely rotatable around the shaft. The second pulleys are arranged opposite to the four first pulleys, respectively.

[0037] Each of the conveying belts 3 is arranged between the first pulley of the driving roller 1 and the second pulley of the idler roller 2. Each of the conveying belts 3 has a plurality of air holes 3a provided at intervals of a certain interval over the entire length thereof. In addition, as shown in Figure 3 , the conveying belt 3 can be configured by a plurality of belts, or can be configured by a single belt.

[0038] The conveying drive section 4 rotates the rotation shaft of the driving roller 1 at a constant speed, thereby moving the conveying belt 3 at a constant speed. By this, the paper arranged on the upper surface (paper conveying surface) of the conveying belt 3 is conveyed toward the paper processing device 102 at a certain speed. The conveying drive section 4 is provided with, for example, a pulley 4a fixed to one end of the rotation shaft of the driving roller 1, a motor 4b having a driving shaft parallel to the driving roller 1, a pulley 4c fixed to the driving shaft of the motor 4b, and an endless belt 4d arranged between the pulley 4a and the pulley 4c.

[0039] For example, the rotation speed of the motor 4b can be made variable. By controlling the rotation speed, the conveying speed of the first conveying section 5 can be adjusted.

[0040] A brake plate (brake) 14 is provided on the upper surface of the conveyor belt 3, which is arranged in a width direction orthogonal to the length direction of the conveyor belt 3. The brake plate 14 can be provided corresponding to each of the conveyor belts 3, or it can be a single plate arranged to traverse the entire conveying surface of the four conveyor belts 3. The brake plate 14 can be moved along the length direction of the conveyor belt 3, and its position can be changed according to the size of the paper discharged from the paper conveying device 100. The brake plate 14 is held by the brake plate holding part 14a.

[0041] like Figure 2 As shown, a feed roller 13 is provided near the connection with the paper handling device 101. The feed roller 13 introduces paper discharged from the paper handling device 101. The paper introduced by the feed roller 13 touches the brake plate 14 at its leading edge and is stacked sequentially in the paper stacking area 15. The paper stacking area 15 is, for example, the area provided between the lower end of the feed roller 13 and the brake plate 14, and its size varies depending on the configuration of the brake plate 14, in other words, depending on the size of the paper.

[0042] In the paper conveying device 100, a first sensor 51 is provided downstream of the paper stacking area 15. The first sensor 51 is used to detect whether the paper has passed through a first paper detection position that is virtually set on the paper conveying path of the first conveying unit 5. The first sensor 51 is provided, for example, at a position where it can be confirmed that the paper is being conveyed stably.

[0043] In the paper conveying device 100, a delivery roller 16 is provided near the connection with the paper processing device 102. The delivery roller 16 collects the paper conveyed from the upper surface of the conveyor belt 3 and discharges it to the paper processing device 102.

[0044] In the paper conveying device 100, a sensor for detecting the passage of paper can be provided on the downstream side of the feed roller 13, for example near the paper discharge section of the feed roller 13. This sensor is used, for example, to count the number of sheets of paper discharged from the paper handling device 101.

[0045] Furthermore, a sensor for detecting paper passage can also be provided on the upstream side of the delivery roller 16, for example near the paper take-up section of the delivery roller 16. This sensor can be used, for example, to count the number of sheets of paper discharged from the paper conveying device 100.

[0046] The paper conveying device 100, for example, includes a suction switching unit 7. Figure 3 As shown, the suction switching unit 7 includes, for example, a suction box 11 and a suction fan (suction source) 12.

[0047] A suction box 11 is disposed between the upper and lower portions of the conveyor belt 3. The suction box 11 has, for example, suction holes 11a on its upper surface. Each suction hole 11a is arranged facing the upper portion of each conveyor belt 3. Furthermore, as...Figure 2 As shown, the suction box 11 includes a gate 11b for opening and closing the suction port 11a. The gate 11b is controlled to open and close by a gate drive unit (not shown). The gate drive unit consists, for example, a lifting mechanism mounted on the gate 11b and a motor mounted on the lifting mechanism.

[0048] like Figure 3 As shown, the suction fan 12 is configured to be directly connected to the suction box 11, for example, to create a negative pressure inside the suction box 11. During the operation of the paper conveying device 100, the suction fan 12 operates continuously, for example.

[0049] Furthermore, the gate 11b is controlled to open and close at specific times. Thus, when the gate 11b is open, paper positioned opposite the suction box 11 is drawn onto the conveyor surface of the conveyor belt 3 through the vent 3a provided on the conveyor belt 3. When the gate 11b is closed, the paper is not drawn onto the conveyor belt 3.

[0050] The various components of the aforementioned paper conveying device 100 are controlled by the control device 50 (see reference). Figure 1 Control. The control device 50 includes, for example, the roller drive unit (not shown) that drives the feed roller 13, and the conveyor drive unit 4 that drives the first conveyor unit 5 (see reference). Figure 3 The control device 50 controls the roller drive unit (not shown) that drives the conveying roller 16. Furthermore, the control device 50 controls the suction switching unit 7, for example, the gate drive unit (not shown) that controls the opening and closing of the gate 11b of the suction box 11, and the fan drive of the suction fan 12.

[0051] Furthermore, the control device 50 is based on the transmission control unit 71 described later (see reference). Figure 5 The control device 50 controls the paper transport by sending a transport request signal. For example, if a transport request signal is received, the control device 50 will transport the paper. More specifically, the control device 50 opens the gate 11b of the suction box 11, causing the bottom layer of paper in the stack to be adsorbed onto the transport surface of the conveyor belt 3, separating it from the remaining paper, and then uses the first transport section 5 to transport the separated paper to the paper handling device 102.

[0052] According to the paper conveying device 100 described above, during operation, paper is introduced from the upstream paper processing device 101 by the feed roller 13, and the leading edge of the paper touches the brake plate 14, and is stacked sequentially in the paper stacking area 15. Furthermore, by opening the gate 11b of the suction box 11, the bottom layer of paper in the stack is sucked onto the conveyor surface of the conveyor belt 3 by the suction box 11, separating it from the remaining paper. Then, by driving the drive roller 1, the bottom layer of paper is supplied to the downstream paper processing device 102 via the conveyor belt 3.

[0053] Next, the paper processing apparatus 102 will be described. The paper processing apparatus 102 is, for example, an apparatus that continuously performs processing in a certain cycle (period). As one example thereof, a rotary die cutter that continuously performs die cutting processing will be described in the present embodiment. Here, "die cutting processing" includes, for example, embossing processing, creasing processing, and perforating processing, and the like.

[0054] As shown in FIG. 1, the paper processing apparatus 102 is, for example, provided with a second conveying section 22 and a die cutting processing section 24. Also, the paper processing apparatus 102 can be provided with an infeed roller 21, a paper positioning roller 23, and the like. Figure 2 The infeed roller 21 introduces the paper conveyed from the paper conveying apparatus 100. The infeed roller 21 is, for example, provided near the connection section with the paper conveying apparatus 100, and discharges the introduced paper to the second conveying section 22. A second sensor 52 for detecting passage of the paper is, for example, provided between the infeed roller 21 and the second conveying section 22. The second sensor 52 outputs a sensor detection signal to the control device 70, for example, when the leading end of the paper in the conveying direction is detected. Alternatively, the second sensor 52 can be omitted as appropriate.

[0055] The second conveying section 22 conveys the paper introduced by the infeed roller 21 to the die cutting processing section 24. The second conveying section 22 is, for example, provided with a suction-type conveying belt (hereinafter, simply referred to as a "conveying belt"). The conveying belt is, for example, provided with a drive roller 31, an idler roller 32, a plurality of endless conveying belts 33 provided between the drive roller 31 and the idler roller 32, a conveying drive section 34, and the like. The drive roller 31 and the idler roller 32 are, for example, configured in the same manner as the first conveying section 5 of the paper conveying apparatus 100 described above.

[0056] The conveying belt 33 can be configured by a plurality of belts as with the conveying belt 3 shown in FIG. 2, or can be configured by a single belt. Also, like the conveying belt 3, the conveying belt 33 has a plurality of air holes (not shown) provided at a certain interval over the entire length thereof.

[0057] Figure 3 The conveying drive section 34 rotates the rotation shaft of the drive roller 31 at a constant speed, for example, thereby moving the conveying belt 33 at a constant speed. By this, the paper disposed on the conveying belt 33 is conveyed to the next die cutting processing section 24. The conveying drive section 34 is, for example, provided with a motor fixed to one end of the rotation shaft of the drive roller 31. Alternatively, as shown in FIG. 3, the motor can be indirectly connected to the drive shaft of the drive roller via a pulley and a belt. Also, the rotation speed of the motor can be made variable.

[0058] The conveying drive section 34 rotates the rotation shaft of the drive roller 31 at a constant speed, for example, thereby moving the conveying belt 33 at a constant speed. By this, the paper disposed on the conveying belt 33 is conveyed to the next die cutting processing section 24. The conveying drive section 34 is, for example, provided with a motor fixed to one end of the rotation shaft of the drive roller 31. Alternatively, as shown in FIG. 3, the motor can be indirectly connected to the drive shaft of the drive roller via a pulley and a belt. Also, the rotation speed of the motor can be made variable. Figure 3

[0059] ​​Further, the paper processing device 102 can also have a suction switching section (not shown) like the paper conveying device 100.

[0060] The die-cutting processing section 24 has a processing roller 35 and a take-up roller 36. The processing roller 35 is arranged, for example, in parallel with the drive roller 31. The take-up roller 36 is arranged so as to face the processing roller 35 with the conveying surface sandwiched therebetween. For example, the take-up roller 36 is arranged in parallel with the processing roller 35 at a fixed interval from the peripheral surface of the processing roller 35. A thin-plate-like cutter 35a (see FIG. 4) is attached to the peripheral surface of the processing roller 35, for example. Figure 6 ).

[0061] The processing roller 35 is rotationally driven by a roller driving section 37. The roller driving section 37 has a motor 42, for example. By rotationally controlling the motor 42 at a specific rotational speed, the processing roller 35 and the take-up roller 36 are synchronously rotated at equal speeds.

[0062] For example, the roller driving section 37 has a pulley 41 connected to one end of the rotational shaft of the take-up roller 36, a motor 42 having a drive shaft parallel to the take-up roller 36, a pulley 43 fixed to the drive shaft of the motor 42, and a looped belt 44 spanning between the pulley 41 and the pulley 43. Further, the take-up roller 36 is rotationally driven at a fixed speed by the motor 42.

[0063] Further, a link mechanism (not shown) is connected to the rotational shaft of the take-up roller 36. By this, the processing roller 35 is rotationally driven in synchronization with the take-up roller 36.

[0064] Further, the configuration of the roller driving section 37 is only an example, and a publicly known roller driving section can be appropriately used.

[0065] A rotational position detecting section 45 is arranged between the take-up roller 36 and the motor 42. As an example of the rotational position detecting section 45, a rotary encoder can be cited. The output pulse of the rotational position detecting section 45 is output to a control device 70 (see FIG. 4). Figure 1 ). The control device 70 calculates the rotational position (0° to 360°) of the reference position P0 virtually set on the processing roller 35, for example, based on the output pulse from the rotational position detecting section 45.

[0066] Further, a paper positioning roller 23 is arranged on the upstream side of the processing roller 35 and the take-up roller 36, which takes up the paper from the second conveying section 22 and supplies it to the processing roller 35.

[0067] Further, a third sensor 53 for detecting passage of the paper is provided at a second paper detection position virtually set between the paper positioning roller 23 and the processing roller 35. In other words, the position of the paper detected by the third sensor 53 is the second paper detection position. The third sensor 53 sends a sensor detection signal to the control device 70 (see FIG. 2) when, for example, the leading end of the paper is detected. Figure 1 Further, a flat support plate for supporting the lower surface of the paper can be provided between the paper positioning roller 23 and the processing roller 35.

[0068] When the paper processing device 102 is in operation, the processing roller 35 and the take-up roller 36 are continuously rotationally driven at a fixed speed by the roller driving section 37. Further, the paper carried in from the paper conveying device 100 by the in-feed roller 21 is conveyed toward the die-cutting processing section 24 by the second conveying section 22. The paper conveyed by the second conveying section 22 passes through the gap of the paper positioning roller 23 and is conveyed to the die-cutting processing section 24. In the die-cutting processing section 24, the paper is die-cut by the cutter 35a (see FIG. 2) when the paper passes between the processing roller 35 and the take-up roller 36. The paper after the die-cutting is conveyed by the third conveying section 25 provided at the next stage and is stacked in a specific stacking area (not shown). Note that the third conveying section 25 can have the same configuration as the second conveying section 22 or a known configuration. Figure 6

[0069] The respective sections of the paper processing device 102 described above are controlled by the control device 70. The control device 70, for example, controls a roller driving section (not shown) that drives the in-feed roller 21, the conveying driving section 34, a roller driving section (not shown) that drives the paper positioning roller 23, the roller driving section 37 that drives the die-cutting processing section 24, and a conveying driving section (not shown) that drives the third conveying section 25. More specifically, the roller driving section (not shown) that drives the in-feed roller 21, the conveying driving section 34, the roller driving section (not shown) that drives the paper positioning roller 23, and the conveying driving section (not shown) that drives the third conveying section 25 are controlled by a paper feeding control section 72. Further, the roller driving section 37 that drives the die-cutting processing section 24 is controlled by a processing control section 73. In addition, the conveying control section 71 supplies the paper to the die-cutting processing section 24 at an appropriate timing in cooperation with the paper feeding control section 72.

[0070] Further, the control device 70 is inputted with sensor detection signals of the second sensor 52 and the third sensor 53 provided on the paper processing device 102. The conveying control section 71 and the paper feeding control section 72 of the control device 70 perform paper conveying and paper feeding based on these sensor detection signals.

[0071] ​Next, the transfer control unit 71 that controls the paper transfer timing of the paper transfer device 100 in the above-described paper processing system 10 will be described. In the present embodiment, as an example, a case where the transfer control unit 71 is mounted on the control device 70 is illustrated, but as described above, it is not limited to this example.

[0072] Figure 4 FIG. is an example of the hardware configuration of the control device 70 according to the present embodiment. As Figure 4 shown, the control device 70 includes, for example: a CPU 81, a storage unit 82 for storing programs executed by the CPU 81 and data referred to using the programs, a main memory 83 that functions as a work area when executing each program, a communication interface 84 for connecting to a network, an input unit 85, a display unit 86, and the like. These units are connected via a bus 88, for example. As an example of the storage unit 82, a magnetic disk such as an HDD (Hard Disk Drive), a magneto-optical disk, a semiconductor memory such as an SSD (Solid State Drive), or the like can be cited.

[0073] Regarding a series of processes for implementing various functions described later, as an example, they are stored in the storage unit 82 in the form of programs (for example, a transfer control program, a paper feed control program, a processing control program, etc.). The CPU 81 reads these programs into the main memory 83 and performs information processing and arithmetic processing to implement various functions. In addition, the program can be in a form pre-installed in the storage unit 82, a form provided in a state stored in another computer-readable storage medium, a form transmitted via a wired or wireless communication method, or the like. As an example of a computer-readable storage medium, a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like can be cited.

[0074] In addition, the control device 50 can also have the same configuration, and a processor such as a CPU reads the program stored in the storage unit into the main memory and performs arithmetic processing, thereby enabling various functions and processes described later to be realized.

[0075] Figure 5 FIG. is a functional block diagram showing an example of the functions implemented by the transfer control unit 71 according to the present embodiment.

[0076] As Figure 5 shown, the transfer control unit 71 includes, for example, a transfer request unit 93, a pass information receiving unit 94, a determination unit 95, and the like. And the transfer control unit 71 can further include a storage unit 90, a timing setting unit 91, and a transfer trigger generation unit 92. In addition, the transfer control unit 71 can further include, for example, a transfer delay notification unit 96. And the transfer control unit 71 can further include a timing correction unit 97.

[0077] The timing setting unit 91 sets the timing of the transfer request corresponding to the processing cycle of the paper handling device 102. For example, the timing setting unit 91 sets the transfer request timing when the paper handling system 10 starts operating. Furthermore, it sets the transfer request timing when settings such as paper size, paper conveying speed, and the rotation speed of the processing rollers change. For example, this can be achieved through the input unit 85 (see reference 85) of the control device 70. Figure 4 The input and setting parameters include paper size, paper feed speed, and processing roller rotation speed. Alternatively, a configuration can be adopted that receives data from other control devices (such as a host device) via a network.

[0078] As described above, the paper handling apparatus 102 performs processing (die-cutting) in a specific cycle during operation. Therefore, it is necessary to supply paper to the processing roller 35 at an appropriate time corresponding to the processing cycle. The timing setting unit 91 sets the timing of the paper delivery request in conjunction with this periodic and continuous processing.

[0079] The following is for reference Figure 6 This section explains when to request the transmission of information.

[0080] like Figure 6 As shown, a cutter 35a is installed within a specific range on the outer periphery of the processing roller 35 of the paper handling apparatus 102. Furthermore, a reference position P0 is set on the processing roller 35. This reference position P0 is a virtual position set to facilitate synchronization with the timing of a transfer request.

[0081] In this embodiment, as an example, when the reference position P0 reaches the lowest point S of the processing roller 35, control is implemented to make the leading edge of the paper reach the lowest point S of the processing roller 35. In the processing roller 35, the distance d1 between the reference position P0 and the leading edge P1 of the cutter 35a is the distance corresponding to the processing start position in the paper. That is, the reference position P0 can be said to be a virtual position that is set each time, corresponding to the leading edge P1 of the cutter 35a and the processing start position of the paper.

[0082] The timing of the paper transfer request can be calculated, for example, based on the distance L1 between the lowest point S of the processing roller 35 and the setting position of the third sensor 53, the distance L2 between the third sensor 53 and the second sensor 52, the distance L3 between the second sensor 52 and the first sensor 51, as well as the rotational speed v1 of the processing roller 35 and the paper transfer speed v2. Furthermore, the paper transfer speed in the paper transfer device 100 and the paper transfer speed in the paper handling device 102 are set to the same speed. Additionally, the second sensor 52 can be omitted; in this case, it can be set to the distance (L2+L3) between the third sensor 53 and the first sensor 51.

[0083] For example, the time t from when the paper passes through the first sensor 51 until it reaches the lowest point S of the processing roller 35 (hereinafter referred to as "transfer time") can be expressed by the following formula.

[0084] t=(L1+L2+L3) / v2 (1)

[0085] Therefore, the transfer request timing is set before time t after the reference position P0 of the processing roller 35 reaches the lowermost point S of the processing roller 35. In other words, as Figure 6 As shown, the timing of the transmission request is when the reference position P0 reaches the rotation position P2.

[0086] Furthermore, the distance d2 between the reference position P0 and the rotation position P2 can be expressed by the following formula (2).

[0087] d2=v1×t (2)

[0088] Here, the distances L1 to L3, rotational speed v1, and paper conveying speed v2 mentioned above are, for example, values ​​based on design values. Furthermore, in a system where the rotational speed v1 of the processing roller 35 and the paper conveying speed v2 are variable, input setting values ​​corresponding to each time can be used.

[0089] The timing information for the transmission request set by the timing setting unit 91 is stored in the storage unit 90. For example, the storage unit 90 stores judgment conditions for determining the timing of the transmission request. As judgment conditions, information about the rotational position P2 of the processing roller 35 can be listed, for example. More specifically, information such as the angle information of the rotational position P2 relative to the reference position P0, the distance d2 from the reference position P0 to the rotational position P2, and the time information from the reference position P0 passing the lowest point S to the rotational position P2 can be listed.

[0090] In this embodiment, as transmission request timing information, the following description illustrates the case where the rotation position P2 is stored in the storage unit 90. Furthermore, since rotation position P2 is used to determine the timing of a transmission request, it will be referred to as "transmission determination position P2" below.

[0091] The transfer triggering unit 92 triggers a transfer based on transfer request timing information stored in the storage unit 90. For example, when the transfer judgment position P2 stored in the storage unit 90 matches the reference position P0, the transfer triggering unit 92 triggers a transfer. For example, the transfer triggering unit 92 calculates the rotational position (0° to 360°) of the reference position P0 virtually set on the processing roller 35 based on the output pulse from the rotational position detection unit 45. Then, when the rotational position of the reference position P0 matches the transfer judgment position P2, a transfer trigger occurs.

[0092] When a transfer trigger occurs via the transfer trigger generation unit 92, the transfer request unit 93 sends a transfer request signal to the control device 50 of the paper feed device 100. More specifically, when a normal transfer signal is input from the judgment unit 95 (described later), the transfer request unit 93 sends a transfer request signal in the next paper feed trigger. On the other hand, when a transfer delay signal is input from the judgment unit 95, the transfer request unit 93 does not send a transfer request signal in the next paper feed trigger, that is, it cancels sending the transfer request signal at that time and instead waits for a paper feed trigger to occur.

[0093] If a delivery request signal is received, the control device 50 of the paper delivery device 100 will feed paper. Specifically, the control device 50 opens the gate 11b of the suction box 11, separating the bottom layer of paper stacked in the paper stacking area 15 from the remaining paper. In this way, the separated sheet of paper is supplied to the paper handling device 102 via the conveyor belt 3.

[0094] In the paper conveying device 100, when the first sensor 51 detects the passage of paper, it outputs a sensor detection signal to the control device 50. Upon receiving the sensor detection signal, the control device 50 sends a paper passage signal to the control device 70.

[0095] Here, it is preferable that the first sensor 51 outputs a sensor detection signal when it detects the leading edge of the paper. For example, if the trailing edge of the paper is to be detected, the time from when the paper size changes to when it reaches the trailing edge changes, thus making the calculation process more complex. Furthermore, since the reference position P0 in the processing roller 35 is set in conjunction with the leading edge of the paper, it is also preferable to detect the leading edge of the paper from the viewpoint of simplifying the calculation process. The same applies to the second sensor 52 and the third sensor 53.

[0096] The transmission control unit 71 receives the paper transmission signal via the information receiving unit 94.

[0097] The determination unit 95 determines whether there is a transmission delay based on the timing of receiving the paper passing signal. For example, the determination unit 95 determines whether a transmission delay has occurred by checking whether a paper passing signal has been received within a specific period after the transmission request signal is sent according to the transmission request unit 93.

[0098] For example, based on the time required for the paper conveying device 100 to convey paper according to the conveying request signal sent from the conveying control unit 71 until the paper reaches the set position of the first sensor 51, and the adjustment time determined based on the mechanical properties of the paper positioning roller 23, a specific period is set. For example, in the paper conveying device 100, even if there is a slight deviation (error) in the conveying timing, as long as the time deviation is within the range that can be adjusted using the paper positioning roller 23, the paper can be supplied to the processing roller 35 at an appropriate supply timing by adjusting (including stopping the rotation) the speed of the paper positioning roller 23. However, if the conveying timing deviation exceeds the range that the paper positioning roller 23 can adjust, the time deviation cannot be absorbed by the paper positioning roller 23, and therefore, it is necessary to stop the paper feeding for one processing cycle and restart the paper feeding in the next processing cycle. As described above, the "specific period" is equivalent to the time range of the paper conveying timing that the paper positioning roller 23 can adjust. For example, the "specific period" can be set by combining the acceleration and deceleration range of the drive motor that drives the paper positioning roller 23, and the paper supply speed at which the paper positioning roller 23 can firmly hold (hold) the paper.

[0099] For example, if a paper-passing signal is received within a specific period after sending a transmission request signal, the determination unit 95 outputs a transmission normal signal. On the other hand, if no paper-passing signal is received within the specific period, a transmission delay signal is output. For example, a transmission normal signal is output to the transmission request unit 93. Furthermore, a transmission delay signal is output to both the transmission request unit 93 and the transmission delay notification unit 96.

[0100] When a transmission delay signal is input, the transmission delay notification unit 96 outputs the transmission delay signal to the paper feed control unit 72. If a transmission delay signal is input, the paper feed control unit 72 pauses the paper positioning roller 23 and adjusts the timing of feeding paper to the processing roller 35. The control performed by the paper feed control unit 72 will be explained later.

[0101] The timing correction unit 97 corrects the delivery request timing information stored in the storage unit 90. For example, the delivery request timing set by the timing setting unit 91 is a theoretical value obtained through calculation. However, in actual operation, the time it takes for the first delivery unit 5 to feed paper, and the time required to remove a sheet of paper from the paper stacking area 15 and move it, will deviate from the theoretical value due to various errors such as the delivery speeds of the first delivery unit 5 and the second delivery unit 22. Similarly, the rotational speed of the processing roller 35 may also change due to deviations caused by the up-and-down movement of the processing roller. The purpose of the timing correction unit 97 is to correct these deviations. Details regarding the correction method of the timing correction unit 97 will be explained later.

[0102] Next, the various processes performed by the aforementioned transmission control unit 71 will be described with reference to the accompanying drawings.

[0103] Figure 7 This is a flowchart illustrating an example of the processing steps performed by the transport control unit 71 and the control device 50 of the paper transport device 100. As an example, the series of processes performed by the transport control unit 71 described below are stored in the storage unit 82 in the form of a program (e.g., a transport control program). Figure 4 In the CPU (processor) 81, the program is read into the main memory 83, where it is processed and executed to perform a series of operations. The control device 50 does the same.

[0104] First, during operation, the transport control unit 71 triggers a transport request (SA1) at the time of the transport request corresponding to the processing cycle, and sends a transport request signal (SA2) to the control device 50 of the paper transport device 100 at the time of the transport trigger. Upon receiving the transport request signal (SA3), the control device 50 transports the paper (SA4). Then, when the first sensor 51 detects the passage of paper (SA5), the control device 50 sends a paper passage signal to the transport control unit 71 (SA6).

[0105] Upon receiving a paper-pass signal (SA7), the transport control unit 71 determines whether a transport delay has occurred. For example, it determines whether a paper-pass signal has been received within a specific period after the transport request signal was sent (SA8). Based on the determination result, if a paper-pass signal is received within the specific period, it is determined that there is no transport delay (SA8: No), and the process returns to step SA1. Thereby, when the next transport trigger occurs, a transport request signal is sent to the control unit 50 of the paper transport device 100 (SA1, SA2).

[0106] On the other hand, in step SA8, if, for example, no paper passage signal is received within a specific period, it is determined that there is a transmission delay (SA8: Yes), and a transmission delay signal is output to the paper feed control unit 72 (SA9). Thereby, as described later, the paper feed control unit 72 of the control device 70 processes the timing of adjusting the paper when the transmission delay occurs.

[0107] Next, if a transmission trigger (SA10) occurs, no transmission request signal (SA11) is sent at the time of the transmission trigger, and the process returns to step SA1.

[0108] As described above, in step SA8, when a transmission delay is determined to have occurred, a transmission request signal is not sent when the next transmission trigger occurs. In other words, the transmission request signal is cancelled, and the device enters a standby state until the next transmission trigger occurs. This prevents multiple sheets of paper from remaining in the paper handling device 102 due to the next sheet being transmitted, even if a transmission delay occurs.

[0109] Furthermore, if paper jamming occurs, the supply of paper to the processing roller 35 must be stopped beyond what is necessary. Therefore, if control is performed as described in this embodiment, paper feeding can be started quickly without needing to stop it beyond what is necessary. As a result, a decrease in processing efficiency can be suppressed.

[0110] Next, the processing performed by the paper feed control unit 72 when the paper handling system 10 is in operation will be described. Furthermore, regarding the series of processing described later, as an example, the processing is stored in the storage unit 82 of the control device 70 in the form of a program (e.g., a paper feed control program). Figure 4 In the CPU 81, the program is read into the main memory 83, where it is processed and executed to perform various functions.

[0111] Figure 8 This is a flowchart illustrating an example of a paper feeding control process performed by the paper feeding control unit 72.

[0112] First, if paper is detected using the third sensor 53 (SB1: Yes), it is determined whether there is an input transmission delay signal (SB2). Specifically, it is determined whether there was an input transmission delay signal during the previous paper detection using the third sensor 53 and the current paper detection.

[0113] If the result is no input transmission delay signal (SB2: No), then the paper is supplied to the processing roller 35 using the paper positioning roller 23 (SB3), and the process returns to step SB1.

[0114] On the other hand, if a transmission delay signal is input (SB2: Yes), the paper positioning roller 23 is stopped, and paper supply is paused (SB4). That is, if a transmission delay signal is input, it can be known that the paper detected by the third sensor 53 is paper with a transmission delay in the paper conveying device 100. If such paper is directly supplied to the processing roller 35, a positional deviation exceeding the error range will occur, resulting in defective products. Therefore, in this case, paper feeding should be paused, and the device should enter a standby state until the next paper feeding opportunity.

[0115] In addition, the "paper feeding timing" is determined based on the rotational speed of the processing roller 35, the distance L1 between the processing roller 35 and the third sensor 53, and the rotational speed of the paper positioning roller 23. The method for determining the timing can be found in the method for setting the "transfer request timing" described above.

[0116] Subsequently, when the reference position P0 of the processing roller 35 (refer to...) Figure 6 When the paper feed is close to the lowest point S and the next paper feeding opportunity arrives, the paper feeding control unit 72 restarts the rotation of the paper positioning roller 23, supplies paper to the processing roller 35 (SB5), and returns to step SB1.

[0117] Thus, when a paper transport delay occurs in the paper transport device 100, the transport control unit 71 outputs a transport delay signal to the paper feed control unit 72 to notify of the delay. This allows the paper feed control unit 72 to adjust the paper supply timing for when a transport delay occurs. Specifically, when a transport delay occurs, the paper positioning roller 23 is paused, canceling one processing cycle and entering a waiting state, so that paper is supplied at the appropriate feeding timing in the next processing cycle. This ensures that even with a transport delay, the paper leading edge and the reference position P0 remain aligned, enabling die-cutting at the appropriate position.

[0118] Furthermore, in order to time the process correctly, when one cycle of processing is canceled and the paper is put into a waiting state in the paper handling device 102, the paper conveying on the paper conveying device 100 side is also in a standby state. Figure 7 (SA10, SA11). In this way, the paper feeding in the paper handling device 102 and the conveying in the paper conveying device 100 can be linked, which can prevent multiple sheets of paper from being stuck in the paper handling device 102.

[0119] Next, refer to Figure 9 Timing correction unit 97 (refer to) Figure 6 The method for correcting the timing of transmission requests will be explained. Figure 9 This is a flowchart illustrating an example timing correction process performed by the timing correction unit 97.

[0120] There is no particular limitation on the timing of the transmission request timing correction. For example, it can be performed when a specific time interval or processing offset exceeds a fixed value after the transmission request timing is set by the timing setting unit 91. Furthermore, the timing correction unit 97 is used to correct the transmission request timing when the paper handling system 10 is in operation, that is, when processing is performed using the processing roller 35.

[0121] For example, such as Figure 7 As shown, based on the current transmission request timing stored in the storage unit 90, a transmission request signal is sent to the control device 50 to feed paper. When the first sensor 51 detects that the paper has passed, a paper passing signal is sent from the control device 50.

[0122] Subsequently, when the paper is conveyed from the paper conveyor 100 to the paper processing unit 102 and detected by the third sensor 53 (SC1), the timing correction unit 97 infers the rotational position of the reference position P0 when the leading edge of the paper reaches the lowest point S of the processing roller 35 (SC2) based on the detection timing of the third sensor 53. This inferred position can be calculated by calculation based on the rotational position of the reference position P0 in the processing roller 35 when the paper is detected by the third sensor 53, the distance L1 between the third sensor 53 and the lowest point S of the processing roller 35, the rotational speed v1 of the processing roller 35, and the conveying speed v2 of the paper.

[0123] Next, the timing correction unit 97 calculates the difference X between the estimated rotational position of the reference position P0 and the lowest point S of the processing roller 35 (SC3). Then, the current transfer judgment position P2, which is stored in the storage unit 90, is corrected using the difference X (SC4). Specifically, if the estimated rotational position of the reference position P0 exceeds the lowest point S, the transfer judgment position P2 is corrected according to the difference X in the direction closer to the lowest point S. This delays the timing of the transfer request signal corresponding to the difference X. On the other hand, if the estimated rotational position of the reference position P0 has not reached the lowest point S, the transfer judgment position P2 is corrected according to the difference X in the direction farther from the lowest point S. This advances the timing of the transfer request signal corresponding to the difference X.

[0124] By correcting the conveying judgment position P2 in this way, the deviation between the paper front end and the reference position P0 of the processing roller 35 can be reduced, and the processing position deviation can be controlled within a specific error range.

[0125] If the timing correction unit 97 corrects the transmission judgment position P2, the corrected transmission judgment position P2 is saved to the storage unit 90 (SC5). In this way, the transmission judgment position P2 previously saved in the storage unit 90 is updated to the corrected transmission judgment position P2, and then a transmission trigger is generated based on the updated transmission judgment position P2.

[0126] As described above, the following effects can be achieved by the transmission control device and transmission control method according to this embodiment.

[0127] For example, the conveying control unit (conveying control device) 71 according to this embodiment includes: a conveying request unit 93, which sends a conveying request signal to the paper conveying device 100 at a conveying request timing corresponding to the processing cycle of the paper handling device 102; an information receiving unit 94, which receives a paper passing signal indicating that the paper has been delivered by the paper conveying device 100; and a determination unit 95, which determines whether there is a conveying delay based on the timing of receiving the paper passing signal.

[0128] Subsequently, if the determination unit 95 determines that no transmission delay has occurred, the transmission request unit 93 sends a transmission request signal at the transmission request timing corresponding to the next processing cycle. On the other hand, if the determination unit 95 determines that a transmission delay has occurred, it does not send a transmission request signal at the transmission request timing corresponding to the next processing cycle, and waits until the next transmission request timing.

[0129] As described above, in the paper conveying device 100, if no paper conveying delay occurs, the paper is conveyed at the next processing opportunity, thereby enabling the paper to be supplied at the appropriate time in conjunction with the processing opportunities. This ensures that the processing capacity of the paper handling device 102 is not reduced, achieving continuous operation.

[0130] Furthermore, if a paper conveying delay occurs in the paper conveying device 100, the paper will not be conveyed at the next processing time. In this way, even if a conveying delay occurs, the situation where multiple sheets of paper are stuck in the paper handling device 102 due to the next sheet being conveyed can be avoided.

[0131] Furthermore, if paper jamming occurs, the supply of paper to the processing roller 35 must be stopped beyond what is necessary. Therefore, if control is performed as described in this embodiment, paper feeding can be started quickly without needing to stop it beyond what is necessary. As a result, a decrease in processing efficiency can be suppressed.

[0132] Furthermore, the conveying control unit (conveyor control device) 71 according to this embodiment includes a timing correction unit 97 for correcting the timing of conveying requests. The timing correction unit 97 infers the actual processing position relative to the paper based on the timing of the paper passing through the paper detection position provided in the paper handling apparatus 102 and located upstream of the die-cutting processing unit 24 where processing is performed, and corrects the timing of the conveying request based on the deviation between the inferred processing position and a preset reference processing position.

[0133] This allows for the correction of the timing of the transfer request based on the actual processing position during operation, enabling the transfer request signal to be sent at the appropriate time corresponding to the operating state. Consequently, processing position deviations can be controlled within a specific error range.

[0134] Alternatively, instead of using the inferred position of the processing position, the timing of the delivery request can be corrected based on the deviation between the actual processing position of the paper and the preset reference processing position.

[0135] Furthermore, the conveying control unit (conveyor control device) 71 according to this embodiment is equipped with a conveying delay notification unit 96, which notifies the paper feed control unit 72 of a conveying delay signal if a paper pass signal is not received within a specific period.

[0136] This allows the paper feeding control unit 72 to be notified in advance of any delivery delay. As a result, the paper feeding control unit 72 can adjust the timing of paper delivery delays and supply paper to the die-cutting unit 24 at an appropriate time.

[0137] Furthermore, in this embodiment, the control device 70 is shown to have the function of the transmission control unit 71, but it is not limited to this. The transmission control unit 71 may be mounted in the control device 50 or in a higher-level control device of the control device 70. Moreover, the transmission control unit 71 may also exist as a separate control device.

[0138] As described above, when the conveying control unit 71 is mounted on a device different from the control device 70, information exchanged between the various components of the paper handling apparatus 102 and the conveying control unit 71 can be transmitted and received via a network (communication medium). For example, information to be transmitted and received may include conveying delay signals, output pulses from the rotation position detection unit 45, or the rotation position of the processing roller calculated based on the output pulses.

[0139] The present invention has been described above through embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments. Various changes or modifications can be made to the above embodiments without departing from the spirit of the invention, and such changes or modifications are also included within the technical scope of the present invention. Furthermore, the above embodiments can also be appropriately combined.

[0140] Furthermore, the information prompting process described in the above embodiments is only one example. Without departing from the spirit of the present invention, redundant steps may be deleted or new steps may be added, or the processing order may be changed.

[0141] For example, in the above embodiment, the determination unit 95 determines whether a transmission delay has occurred based on whether a paper-passing signal has been received within a specific period after the transmission request signal is sent. However, the method for determining whether a transmission delay has occurred is not limited to this example. For example, the rotational position of the reference position P0 of the processing roller 35 when the paper-passing signal is received can be obtained from the rotational position detection unit 45, and the transmission delay can be determined based on whether the rotational position is within a specific position range of the processing roller 35. Here, the "specific position range" is, for example, a position range equivalent to the "specific period" mentioned above, and can be calculated based on the transmission determination position P2 and the rotational speed of the processing roller 35 through calculation.

[0142] Furthermore, as described above, when a conveying delay is determined based on the rotational position of the reference position P0 of the processing roller 35 when the paper passage signal is received, the timing correction unit 97 can also correct for a "specific position range". In this case, the timing correction unit 97 can, for example, temporarily store the rotational position of the processing roller 35 when the paper passage signal is received as a temporary paper passage determination position, and correct the stored temporary paper passage determination position using the aforementioned difference X. Then, with the corrected paper passage determination position as the center, a specific range of margin is left before and after, thereby correcting the "specific position range". In addition, this specific range of margin corresponds to the rotational position range within a specific period.
