Description

This disclosure relates to a processing machine.

Conventionally, processing machines have been used to perform various processes, such as cutting, folding, and gluing, on a variety of objects. For example, slitter machines have been used to separate thin sheet-like objects along the conveying direction using slitter blades (see, for example, Patent Document 1).

When processing with a slitter machine, the sheet is supplied to the machine in the form of a wound roll. Since the length of the sheet on one winding roll is finite, the entire roll is processed by splicing together multiple winding rolls. In this process, splicing each winding roll is done manually. When performing this process, other tasks such as applying tape to specified locations are also performed.

JP 2015-202989 A

However, with conventional processing machines such as the slitter machine mentioned above, processing by the processing machine and work by the operator coexist, which creates the problem of making it difficult for the operator to continue working smoothly when the processing machine is stopped.

Preferred embodiments of the present disclosure are described in detail below with reference to the drawings.

<1. Overview of the processing machine>
The processing machine according to this embodiment includes a conventional processing machine main body, a mechanism for controlling the processing machine main body, and a mechanism for notifying the user of the operation. First, an overview of the processing machine main body included in the processing machine according to this embodiment will be described. FIG. 1 is a side view showing an overview of the processing machine main body. FIG. 2 is a detailed view of the slit processing unit 20 in FIG. 1. In this embodiment, an example will be described in which a slitter machine that slits (cuts) a sheet S unwound from a winding roll is used as the processing machine main body. In particular, this embodiment will describe an example in which a slitter machine that slits a sheet formed with many fine through-holes, called Magic Cut (registered trademark), and inspects the through-holes will be used.

The processing unit 10 includes an unwinding unit 11 that unwinds and supplies the sheet S from a set winding roll, a winding unit 12 that winds up each slit and separated sheet, and transports the sheet via multiple transport rollers 13. In the example shown in Figure 1, it includes transport rollers 13a to 13j. A slitting unit 20 is provided midway, slitting the sheet S along the sheet S's transport direction. For example, if there are nine slitting units 20, one wide sheet S is separated into ten rows of sheets S. The separated sheets S are then wound up by the winding unit 12. In the side view of Figure 1, two winding units, 12a and 12b, are visible, arranged one above the other. The other eight winding units 12 are hidden behind the paper. Five of the ten winding units 12 are arranged on the upper shaft (upper side) and five on the lower shaft (lower side). Each element of the processing unit 10 is housed in a housing 15 shown by the dashed line.

As shown in FIG. 2, the slitting unit 20 has a slit blade holder 23 near the two conveying rollers 13f, 13g. The slit blade holder 23 holds a slitting blade (not shown) and moves to a position where the slitting blade comes into contact with the sheet S during slitting. The sheet S slit by the slitting blade near the upper conveying roller 13f is then conveyed by the lower conveying roller 13g. As shown in FIG. 2, a laser sensor 14 is disposed at a position that sandwiches the sheet S flowing between the upper and lower conveying rollers 13f, 13g. The laser sensor 14 is composed of a laser emitter 14a and a laser receiver 14b. The laser emitter 14a and the laser receiver 14b are disposed opposite each other, sandwiching the sheet S flowing between the upper and lower conveying rollers 13f, 13g.

<2. Device configuration>
The processing machine according to this embodiment will now be described. Fig. 3 is a functional block diagram showing the configuration of the processing machine according to this embodiment. As shown in Fig. 3, the processing machine according to this embodiment has a processing unit 10, a control unit 30, a display unit 51, an instruction unit 52, and an audio output unit 60.

The processing unit 10 is the main body of the processing machine that performs the specified processing, and in this embodiment is a slit processing machine as shown in Figures 1 and 2. The control unit 30 is a means for controlling the entire processing machine according to this embodiment, including the processing unit 10. The control unit 30 performs specified calculations and controls, and is realized by a programmable logic controller (PLC). The control unit 30 can also be realized by a general-purpose computer equipped with a CPU, main memory, and non-volatile storage device. When the control unit 30 is realized by a computer, programs for controlling the processing unit 10, display unit 51, instruction unit 52, and audio output unit 60 are stored in the storage device, and the CPU reads the programs into the main memory and executes them.

The memory device stores information about the items to be processed. Each item is managed by a product number code, which is identification information that specifies the item's product number, and each item is associated with a customer code, which is identification information that specifies the customer who made the request. Each item is associated with the work to be performed and stored. Each work is managed as a unit work and a work set consisting of multiple unit works. In other words, the memory device in the control unit 30 stores one or more unit works associated with each work set. As described below, the worker can set the work set required for each item by operating the touch panel. Based on the worker's instructions, the control unit 30 associates the item code with the work set and stores them in the memory device.

The display unit 51 is a display means for displaying the status of the processing unit 10, and is realized by a display device such as a liquid crystal display or an organic EL display. The instruction unit 52 is a means by which the operator gives instructions to the control unit 30. The instruction unit 52 may be realized in any manner as long as it is possible to give instructions to the control unit 30. In this embodiment, the display unit 51 and the instruction unit 52 are realized by a touch panel 50. Therefore, in this embodiment, the instruction unit 52 is realized by instruction buttons, etc. displayed on the display unit 51. The operator gives instructions to the control unit 30 by touching the instruction buttons displayed on the display unit 51. The audio output unit 60 is equipped with a speaker and outputs information received from the control unit 30 as audio.

Based on the information received from the processing unit 10, the control unit 30 displays various information on the display unit 51 and outputs audio from the audio output unit 60. Furthermore, the control unit 30 controls the processing unit 10 according to the item based on the item information stored in the storage device. Furthermore, the control unit 30 displays screen data on the display unit 51 for input by the worker using the touch panel 50, and recognizes the position touched by the worker and executes the corresponding process.

<3. Item Settings>
Next, we will explain how to set items in the processing machine according to this embodiment. Setting items refers to setting the necessary operations for each item to be processed in the processing unit 10. Display screens such as those shown in FIGS. 4 to 6 are used when setting items. First, we will explain the display screens displayed on the display unit 51 when setting items. FIG. 4 is a diagram showing an initial screen. In the initial state, the initial screen shown in FIG. 4 is displayed on the display unit 51. On the initial screen, the system name "Voice Guidance System" is displayed at the top of the screen. In this embodiment, the voice output unit 60 also notifies users of operations by voice, so the system is referred to as the "Voice Guidance System." Furthermore, two buttons, "New Registration" and "Call," are displayed at the bottom of the initial screen. On the initial screen, the operator can select either of these two buttons. In this embodiment, the display unit 51 and the instruction unit 52 are implemented by a touch panel 50. Therefore, when the operator touches a button displayed on the display unit 51, the control unit 30 recognizes the instruction or selection corresponding to that button.

Figure 5 shows the new registration screen. The new registration screen is used when registering a new item. When the operator selects the "New Registration" button on the initial screen in Figure 4, the new registration screen is displayed. In the lower right corner of the new registration screen, there are input fields for "Customer Code" and "Product Code." "Customer Code" is identification information that identifies the customer, and "Product Code" is identification information that identifies the product number, which is the number of each item.

For one product number (item), the required work set can be selected on the new registration screen. A work set is a combination of multiple unit operations. In the processing machine of this embodiment, the following work sets can be selected. Multiple work sets can be selected for each of the following: when the slit sheet is stopped at the end of winding, which is when it is wound onto the winding section 12, and when joining the ends of the sheet on the winding roll.

(When winding is stopped)
(1) Check the outside of the roll. Pattern 1: The outside cut position is specified. Pattern 2: The outside cut position is not specified. (2) Check the core cut position. (3) Check the fastening tape. (4) Paper core fastening cut. (5) Check the end tape. Pattern 1: The end tape has a tab. Pattern 2: The end tape does not have a tab.

(Joint Relationship)
Pattern 1: With exposed edges + double-sided adhesive Pattern 2: Without exposed edges + double-sided adhesive Pattern 3: With exposed edges + surface adhesive Pattern 4: Without exposed edges + surface adhesive

On the new registration screen in Figure 5, the names of each work set for winding end stop are displayed on the left side of the screen, with a selection button (shown as an oval outline in the figure) displayed to the right of each work set name. Additionally, the names of each splicing-related work set are displayed in the center of the screen, with a selection button (shown as an oval outline in the figure) displayed to the right of each work set name. When the worker touches the selection button displayed to the right of each work set name, that work set is selected as the work set required for the product number code displayed in the lower right of the screen.

The reset button and new registration button are displayed on the right side of the new registration screen in Figure 5. When the reset button is operated by the worker, all previously selected work sets are reset and no longer selected. When the new registration button is operated by the worker, the control unit 30 associates all previously selected work sets with product number codes and registers them in the storage device. In this way, the necessary work sets for each item are registered in the storage device.

Figure 6 shows the call screen. The call screen is used when modifying an item that has already been registered. The call screen is displayed when the "Call" button is pressed on the initial screen of Figure 4. Similar to the new registration screen of Figure 5, the lower right of the call screen has input fields for "Customer Code" and "Product Code." On the call screen, you can enter the "Customer Code" and "Product Code" to call up the corresponding work set information.

The call screen in Figure 6 is the same as the new registration screen in Figure 5, except for the buttons on the right side of the screen. A reset button is displayed on the right side of the call screen in Figure 6, just like the new registration screen in Figure 5. However, the call screen in Figure 6 displays a call button instead of the new registration button in Figure 5. Additionally, a check transfer button is displayed. When the worker touches the check transfer button, the control unit 30 associates all corrected work sets with product number codes and registers them in the storage device. In this way, the necessary work sets for each item are registered in the storage device.

Once an item is registered on the new registration screen in Figure 5, the item can be processed by the processing unit 10. Processing by the processing unit 10 then begins. In other words, the processing unit 10, which is the main processing machine body, is operated. Figure 7 is a diagram showing the operation screen. The operation screen is a screen that shows the state while the main processing machine body is operating, i.e., while processing by the processing unit 10 is in progress. As described above, the main processing machine body in this embodiment performs magic cut processing and inspection (checking) in parallel with slit processing. For this reason, "Checking" is displayed at the top of the operation screen in Figure 7.

On the left side of the operation screen in Figure 7, the measured length and number of splices are displayed. The measured length is the length of the sheet being processed, and is obtained by measuring it using a yardmeter (not shown) equipped in the processing unit 10. The number of splices is the number of times the winding roll has been spliced. While the processing unit 10 is operating, the numbers for the measured length and number of splices continue to increase. The example in Figure 7 shows the state when the measured length is 510 m (meters) and the number of splices is 1.

The confirmation operation settings are displayed on the right side of the operation screen in Figure 7. In the example in Figure 7, the confirmation operation settings for the four items - end tape check, upper shaft edge extension, lower shaft edge extension, and meandering check - are displayed as 100 cm, 310 cm, 50 cm, and 230 cm, respectively.

4. Processing Operation
Next, the processing operation of the processing machine according to this embodiment will be described. FIG. 8 is a flowchart showing the processing operation of the processing machine according to this embodiment. The processing operation of the processing machine according to this embodiment differs depending on the operation set set for the item. FIG. 8 explains a case where the joining relationship pattern 1 "with selvage + with double-sided pasting" is set as the operation set. More specifically, a case where the joining relationship "pattern 1 with selvage + with double-sided pasting" is set on the new registration screen of FIG. 5 or the call screen of FIG. 6 will be explained.

The processing machine according to this embodiment operates the processing unit in the same way as a normal processing machine (step S1). That is, normal processing is performed by the processing unit 10. As described above, in this embodiment, slit processing is performed. When the processing unit 10 is operating, the running position is constantly checked using a yard meter. Measurement results from the yard meter are sent to the control unit 30. The control unit 30 then displays the measurement results on the display unit 51. When the processing unit 10 is operating, an operation screen such as that shown in Figure 7 is displayed on the display unit 51.

When the measurement result from the yard meter reaches a predetermined value, the processing unit 10 stops operation (step S2). The end-of-winding position is preset for each item. Therefore, when the measurement result from the yard meter reaches the preset end-of-winding position, the control unit 30 stops the processing unit 10. Then, a process to raise the joining table (not shown) is performed (step S3). Specifically, the control unit 30 performs a process to raise the joining table in the processing unit 10. Next, a work set is displayed and an audio output is performed (step S4). Specifically, the control unit 30 displays the contents of the work set to be confirmed on the display unit 51 and outputs audio from the audio output unit 60.

Figure 9 is a diagram showing a confirmation screen displayed on the display unit 51. In step S4, the display unit 51 displays a confirmation screen as shown in Figure 9 for joint pattern 1 (with selvedge + double-sided application). For joint pattern 1 (with selvedge + double-sided application), as shown in Figure 9, three unit operations are displayed vertically near the center of the confirmation screen. A confirmation button is displayed to the right of each unit operation. In the example of Figure 9, three confirmation buttons, Ba, Bb, and Bc, are displayed from top to bottom. When the confirmation screen is first displayed, all confirmation buttons display "Unconfirmed." When a confirmation button is operated, it displays "Confirmed." It is preferable to change the display mode of the confirmation button between the "Unconfirmed" and "Confirmed" states. The change in display mode may be limited to the change in the text between "Unconfirmed" and "Confirmed." Alternatively, the color of the confirmation button may be changed. For example, a subdued color and a bright color may be used. In this embodiment, the display mode is changed so that the border of the confirmation button is thicker in the "Confirmed" state compared to the "Unconfirmed" state.

In the example of Figure 9, three unit tasks are displayed. This indicates that the three unit tasks of "Confirm splice position, confirm double-sided attachment," "Confirm upper shaft lug protrusion," and "Confirm lower shaft lug protrusion" are unit tasks that make up the task set "Splice pattern 1 with lug protrusion + double-sided attachment." A unit task is a series of tasks performed when the processing unit 10 is stopped and before it is restarted. As such, it does not necessarily have to be one task, but may be two or more tasks. The unit tasks are displayed in order on the screen in one direction according to the order in which they are actually performed. In the example of Figure 9, they are displayed from the top to the bottom of the screen in the order in which they should be performed. In the example of Figure 9, the top unit task is displayed as "Confirm splice position, confirm double-sided attachment." This allows the worker to know that they should perform and confirm the splice and double-sided attachment tasks.

Meanwhile, the audio output unit 60 outputs audio content corresponding to the unit task displayed at the top of the confirmation screen. Specifically, audio guidance is provided to encourage the worker to "check the joining position and double-sided application." For example, audio guidance to encourage the worker to "check the joining position and double-sided application" can output a message such as "Please check the joining position. Please check double-sided application." The worker can know the task they need to perform based on the display on the confirmation screen and the audio guidance.

At this point, the processing unit 10 is stopped with the joining table lowered. In this state, the worker performs the actual work (step S5). That is, the sheets S on the winding roll are joined together on the lowered joining table. This makes the joining work easy. In the case of joining pattern 1, the joining work is performed by attaching the sheets on both sides. The worker then lowers the joining table (step S6). In this work, the worker manually returns the joining table to its original position.

When the worker has completed the actual work, he or she operates the confirmation button on the confirmation screen (Step S7). Specifically, the worker touches the confirmation button corresponding to the unit work that he or she performed. As described above, the unit work is displayed from top to bottom in the order in which it should be performed. Furthermore, the confirmation buttons are displayed in different ways depending on whether they are in the "unconfirmed" or "confirmed" state. Therefore, the worker can simply operate the top confirmation button that is in the "unconfirmed" state without having to carefully read the details of the unit work.

When a confirmation button is operated, the control unit 30 switches the display of the operated confirmation button and the audio output content (step S8). For example, when confirmation button Ba is touched, the display of confirmation button Ba changes from the "unconfirmed" state shown in FIG. 9 to the "confirmed" state shown in FIG. 10. The audio output content output by the control unit 30 from the audio output unit 60 also switches.

As shown in Figure 10, when the display of confirmation button Ba changes to "confirmed," the unit task corresponding to confirmation button Bb, the topmost of the "unconfirmed" confirmation buttons, is displayed as "Confirm upper shaft ear removal." This lets the worker know that the "upper shaft ear removal" task should be performed. "Ear removal" is the task of applying tape to a predetermined position so that it protrudes like an ear from the winding roll and is visible from the outside. "Upper shaft" refers to winding section 12a, which is the upper shaft of the upper and lower winding sections 12a, 12b. "Lower shaft ear removal," described below, refers to performing the ear removal task on winding section 12b, which is the lower shaft.

Meanwhile, the audio output unit 60 outputs audio corresponding to the unit task displayed second on the confirmation screen. Specifically, audio guidance is provided to encourage the operator to "check the upper shaft lug protrusion." For example, audio guidance to encourage the operator to "check the upper shaft lug protrusion" can be output as an audio message such as "Please check the upper shaft lug protrusion." The operator can know the task to be performed based on the display on the confirmation screen and the content of the audio guidance.

Furthermore, when the confirmation button is operated, the control unit 30 resumes operation of the processing unit 10 (step S9). At this time, the processing unit 10 runs the sheet based on instructions from the control unit 30. Then, after resuming operation, when the measurement result from the yard meter reaches a predetermined value, the processing unit 10 stops operation (step S10). Specifically, this is done by stopping the operation after the sheet has run a predetermined distance using the measurement value from the yard meter.

With the processing unit 10 stopped in this way, the worker performs the actual work again (step S11). Specifically, the worker performs the upper shaft edge removal work by following the display content on the display unit 51 and the audio guidance from the audio output unit 60.

When the worker has completed the actual work of removing the upper shaft edge, he or she will again operate the confirmation button on the confirmation screen. Specifically, the worker will touch the confirmation button corresponding to the unit task that he or she performed. At this point, the worker will operate the second confirmation button from the top, Bb. The confirmation button to be operated may be determined by looking at the details of the unit task, or the worker may operate the top confirmation button that is in the "unconfirmed" state.

When the confirmation button Bb is operated, the control unit 30 switches the display of the operated confirmation button and the audio output content (step S12). For example, as a result of operating the confirmation button Bb, the display of the confirmation button Bb changes from the "unconfirmed" state shown in FIG. 10 to the "confirmed" state shown in FIG. 11. The audio guidance output by the control unit 30 from the audio output unit 60 also switches.

As shown in Figure 11, the display of confirmation button Bb has changed to "Confirmed," and "Confirm lower shaft margin" is displayed as the unit task corresponding to confirmation button Bc, which is in the "Unconfirmed" state. This allows the worker to know that they should perform the "lower shaft margin" task.

Meanwhile, the audio output unit 60 outputs audio content corresponding to the unit task displayed third from the top on the confirmation screen. Specifically, audio guidance is provided to encourage the user to "check the lower shaft ear projection." For example, audio guidance encouraging the user to "check the lower shaft ear projection" can be output as an audio message such as "Please check the lower shaft ear projection." The worker can know the task they need to perform based on the display on the confirmation screen and the content of the audio guidance.

Furthermore, when the confirmation button is operated, the control unit 30 resumes operation of the processing unit 10 (step S13). At this time, the processing unit 10 runs the sheet based on instructions from the control unit 30. Then, after resuming operation, when the measurement result from the yard meter reaches a predetermined value, the processing unit 10 stops operation (step S14). Specifically, this is done by stopping the operation after the sheet has run a predetermined distance using the measurement value from the yard meter.

With the processing unit 10 stopped in this way, the worker performs the actual work again (step S15). Specifically, the worker performs the lower shaft edge removal work by following the display content on the display unit 51 and the audio guidance from the audio output unit 60.

When the worker has completed the actual work of removing the lower shaft margin, he or she will again operate the confirmation button on the confirmation screen. Specifically, the worker will touch the confirmation button corresponding to the unit task that he or she performed. At this point, the worker will operate the third confirmation button from the top (the bottom one), Bc. The confirmation button to press can be determined by looking at the content of the unit task, or the worker can press the top confirmation button that is in the "unconfirmed" state. As shown in Figure 11, at this point, there is only one confirmation button left in the "unconfirmed" state, so the worker can easily operate the confirmation button corresponding to the "lower shaft margin confirmation" task that he or she has just completed.

When the confirmation button Bc is operated, the control unit 30 switches the display and audio output of the operated confirmation button Bc (step S16). For example, as a result of touching the confirmation button Bc, the display of the confirmation button Bc changes from the "unconfirmed" state shown in FIG. 11 to the "confirmed" state shown in FIG. 12. The audio guidance output by the control unit 30 from the audio output unit 60 then ends.

Furthermore, by operating the confirmation button, the control unit 30 resumes operation of the processing unit 10 (step S17). At this time, the processing unit 10 runs the sheet S based on instructions from the control unit 30. Thereafter, the processing unit 10 processes the sheet S in the same manner as in step S1. Then, when the running value measured by the yard meter reaches a predetermined value, the processing of steps S1 to S17 is repeated.

As described above, the processing machine according to this embodiment has a processing unit 10 that processes the target object, a control unit 30 that controls the processing unit 10, a display unit 51 that displays information from the control unit 30, and an instruction unit 52 that gives instructions to the control unit 30. The control unit 30 controls the processing unit 10 to stop based on a signal from the processing unit 10, and controls the processing unit 10 to resume operation based on detection of an operation on the instruction unit 52, thereby reducing the occurrence of careless mistakes such as resuming operation of the processing unit before the necessary work has been performed.

In addition, in the processing machine according to this embodiment, the display unit 51 and instruction unit 52 are configured as a touch panel 50, and the unit tasks to be performed and the instruction buttons that serve as the instruction units corresponding to those unit tasks are arranged side by side, so that it is possible to notify the processing machine that each unit task has been performed and confirmed.

In addition, the processing machine according to this embodiment has multiple task sets, each having one or more unit tasks, and each task set is associated with an item. When multiple pairs of unit tasks and instruction buttons corresponding to those unit tasks are displayed, each pair of unit tasks and instruction buttons is arranged on the screen of the display unit 51 from one side of the screen to the other in the order in which the tasks are performed. Therefore, after completing a unit task, the worker can easily inform the processing machine that the unit task has been performed by operating the instruction buttons, for example, in order from top to bottom.

In the above embodiment, the case where the work set is "jointed" pattern 1 (with selvedge + double-sided pasting) was described, but processing is performed in the same way for other patterns. That is, for pattern 2 (no selvedge + double-sided pasting), pattern 3 (with selvedge + surface pasting), and pattern 4 (no selvedge + surface pasting), after registering for an item, the corresponding unit work can be displayed on the display unit 51 and output as an audio message from the audio output unit 60 to notify the worker of the work to be performed.

The same processing is also performed when the operation set is "Stopped at end of winding." That is, even in the cases of (1) outside winding confirmation pattern 1 (with outside winding cut position specified), (1) outside winding confirmation pattern 2 (without outside winding cut position specified), (2) core cut position confirmation, (3) fastening tape confirmation, (4) paper core fastening break, (5) end tape confirmation pattern 1 (end tape with selvedge), and (5) end tape confirmation pattern 2 (end tape without selvedge), after registration for the item, the corresponding unit operation is displayed on the display unit 51 and an audio output is generated from the audio output unit 60 to notify the worker of the operation to be performed.

When the operation set is "joint-related" pattern 2 (no edge protrusion + double-sided lamination), pattern 3 (edge protrusion + surface lamination), or pattern 4 (no edge protrusion + surface lamination), a confirmation screen like that shown in Figures 13, 14, and 15 is displayed after the operation of the processing unit 10 has stopped. Compared to Figure 9 for "joint-related" pattern 1 (edge protrusion + double-sided lamination), the unit operations displayed are different.

When the operation set is "Stopped at the end of winding" (1) Outside winding confirmation pattern 1 (with outside winding cut position specified), (1) Outside winding confirmation pattern 2 (without outside winding cut position specified), (2) Core cut position confirmation, (3) Fastening tape confirmation, (4) Core fastening cut, (5) End tape confirmation pattern 1 (end tape with selvedge), or (5) End tape confirmation pattern 2 (end tape without selvedge), a confirmation screen like those shown in Figures 16 to 22 will be displayed after operation of the processing unit 10 stops. Compared to Figure 9 for "Splicing related" pattern 1 (with selvedge + double-sided lamination), the unit operations displayed are different.

In this embodiment, the laser sensor 14 in the processing unit 10 detects defects in the through holes formed in the sheet S. When a defect is detected, the laser sensor 14 transmits information indicating the presence of a defect to the control unit 30. The control unit 30 acquires the yard meter measurement value at the time when the information indicating the presence of a defect is acquired from the laser sensor 14, and stores this value in the storage device as the defect detection result. The control unit 30 then displays the stored defect detection result on the display unit 51 at a predetermined timing.

Figure 23 shows the defect detection result screen displayed on the display unit 51. As shown in Figure 23, the defect detection result screen displays a title such as "Magic Cut Check." The detection results of each sensor (laser sensor 14) possessed by the processing unit 10 are then displayed. In the example shown, three detection results are displayed below each of the ten sensors. The detection results are the length of the sheet S from the start position of travel measured in yards.

While the preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments and various modifications are possible. For example, while the above embodiments describe a slitter machine equipped with a sensor that detects through holes, any processing machine that processes an object and involves operator work may be used.
