The data transmission status of the transmission unit 14 and the like can be displayed as appropriate.

The display unit 20 may be, for example, an information processing device such as a mobile phone including a smartphone, a tablet terminal, a desktop PC (Personal Computer), a notebook PC, or a PDA (Personal Digital Assistant). Further, the display unit 20 may be a wearable device which is a glasses-type or watch-type information processing terminal.

The production line PL includes a plurality of processing units 300 (300-1, 300-2, 300-3 ...) And a reference encoder RE. The plurality of processing portions 300 include the above-mentioned material coils 201, 205, 211, fiber drum 202, cutting device 203, adhesive coating device 204, 209, 210, 215, slip cutting device 206, 212, temporary press roll 207, It corresponds to various processing devices related to the manufacture of the diaper D, such as 213, the present press devices 208 and 214, the leg hole cutting device 216, the end cutting device 217, and the transport device forming each transport path R1 to R7.

Various sensors Sr (Sr-1, Sr-2, Sr-3 ...) Are connected to the processing unit 300, respectively. The reference encoder RE is an example of a reference device that measures the phase angle of the production line PL.

[2-3. About various sensors and reference encoders]
Here, various sensors Sr and a reference encoder RE will be described. FIG. 3 is a diagram showing an example of the configuration of the processing unit 300. Further, FIG. 4 is an explanatory diagram of the product pitch P. Note that FIG. 3 shows the above-mentioned cutting device 203 as an example of the processing unit 300.

As described above, as shown in FIG. 3, the cutting device 203 includes a cutter roll 203a and an anvil roll 203b. Further, the cutting device 203 has a motor 203c and an encoder 203d.

The motor 203c is a drive source for rotating the cutter roll 203a. The encoder 203d is provided at the shaft end of the motor 203c and measures the rotation angle of the motor 203c (that is, the rotation angle of the cutter roll 203a).

Here, the peripheral length of the cutter roll 203a is set to the same value as the length of the product pitch P, which is the length of one piece of the diaper D shown in FIG. Therefore, when the cutter roll 203a makes one rotation, for example, the absorber Ab is transported by the transport amount corresponding to the length of the product pitch P (hereinafter, appropriately referred to as “unit transport amount”).

Then, the encoder 203d rotates integrally with the motor 203c (that is, the cutter roll 203a), and based on the input of this rotation operation, the encoder 203d corresponds to 0 ° to 360 ° for each unit transfer amount, for example, from 0 to a predetermined upper limit. The digital value up to the value is output in proportion to the amount of transportation.

Such a digital value is transmitted as a reference signal to a control device (not shown) of the production line PL, and is used for a series of interlocking controls by a plurality of processing units 300 in the production line PL. The encoder 203d that outputs such a reference signal is also referred to as a "reference encoder RE" in order to distinguish it from other encoders. In this way, one rotation of the reference encoder RE corresponds to the length of one piece of the diaper D, and the phase angle of the production line PL is measured in association with the length of one piece.

Although the case where the encoder 203d of the cutting device 203 is the reference encoder RE has been described here, the encoder provided in the other processing unit 300 may be the reference encoder RE.

For example, any encoder included in the slip cut devices 206, 212, the temporary press rolls 207, 213, the present press devices 208, 214, the leg hole cut device 216, and the end cut device 217 may be used as the reference encoder RE. Further, any encoder provided in the transport device forming the transport paths R2, R4, R6, R7 and the like may be used as the reference encoder RE. Further, the reference encoder RE does not necessarily have to be an encoder physically provided on the production line PL, and may be a virtual encoder.

Further, as shown in FIG. 3, at least the vibration sensor Sr_A, the pressure sensor Sr_P, and the temperature sensor Sr_T are connected to the cutting device 203 as various sensors Sr.

The vibration sensor Sr_A is, for example, an acceleration sensor, and measures the vibration of the cutting device 203 during the manufacture of the diaper D. The pressure sensor Sr_P measures the pressure of the cutting device 203 during the manufacture of the diaper D, for example, the pressure at which the core wrap sheet Cs on which the absorber Ab is placed is sandwiched and cut. The temperature sensor Sr_T measures the temperature of the cutting device 203 during the manufacture of the diaper D.

[3. Configuration example of high-speed collection unit]
Next, a configuration example of the high-speed collecting unit 12 according to the embodiment will be described with reference to FIGS. 5 to 10. First, FIG. 5 is a block diagram showing an example of the configuration of the high-speed collection unit 12 according to the embodiment.

As shown in FIG. 5, the high-speed collection unit 12 includes a master collection unit 121 and one or more slave collection units 122 (122-1, 122-2, 122-3 ...).

The master collection unit 121 and the slave collection unit 122 are each realized by, for example, a PLC (Programmable Logic Controller). The master collection unit 121 comprehensively controls the high-speed collection process executed by the high-speed collection unit 12.

The slave collecting unit 122 samples data of, for example, the vibration sensor Sr_A among various sensors Sr connected to the plurality of processing units 300, respectively. Although FIG. 5 shows an example in which the slave collecting unit 122 and the vibration sensor Sr_A are associated with each other on a one-to-one basis, the slave collecting unit 122 and the vibration sensor Sr_A are associated with each other on a one-to-many basis. You may.

The master collection unit 121 notifies each of the slave collection units 122 of the data sampling trigger at a predetermined collection timing, and notifies all the slave collection units 122 of the data of the vibration sensor Sr_A synchronously at the same time on the time axis. Is sampled at high speed.

The high-speed sampling referred to here is when the rotation speed of a predetermined motor of the production line PL is equal to or higher than the predetermined value during the production of the diaper D, for example, every 30 minutes for 2 seconds, the sampling cycle is 80 microseconds, and sampling is performed. It is performed under the condition that the score is 22500 points.

Further, the master collection unit 121 stores the data of the vibration sensor Sr_A sampled at high speed in the collection DB 11a in each of the slave collection units 122.

Thereby, for example, the data of each of the vibration sensors Sr_A, which changes drastically even in a short period of time, can be sampled at high speed with high resolution according to the drastic change, and the data useful for generating the learning model 501 can be collected.

In FIG. 5, only the slave collecting unit 122 collects the data of the vibration sensor Sr_A, but the master collecting unit 121 and the slave collecting unit 122 collect the data of the vibration sensor Sr_A associated with the master collecting unit 121. It may be sampled.

A configuration example of the master collection unit 121 and the slave collection unit 122 will be described in more detail. FIG. 6 is a block diagram showing an example of the configuration of the master collection unit 121 included in the high-speed collection unit 12. Further, FIG. 7 is a block diagram showing an example of the configuration of the slave collecting unit 122 included in the high-speed collecting unit 12.

As shown in FIG. 6, the master collecting unit 121 includes a control unit 121a. The control unit 121a is a controller, and for example, various programs stored in a storage device inside the master collection unit 121 by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like are stored in a RAM (Random Access). It is realized by executing Memory) as a work area. Further, the control unit 121a can be realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

The control unit 121a has an acquisition unit 121aa, a generation unit 121ab, and a notification unit 121ac, and realizes or executes the functions and operations of information processing described below.

The acquisition unit 121aa acquires a predetermined collection timing. The acquisition unit 121aa acquires a predetermined collection timing based on, for example, a clock signal output from a clock generation circuit (not shown) included in the collection device 10.

Strictly speaking, the collection timing referred to here is the trigger generation timing for the master collection unit 121. Further, the acquisition unit 121aa acquires a reference signal indicating the phase angle of the production line PL from the reference encoder RE.

The generation unit 121ab generates a data sampling trigger for each of the slave collection units 122 when the above-mentioned collection timing is acquired by the acquisition unit 121aa. The trigger includes, for example, the sampling conditions described above. The notification unit 121ac notifies each of the slave collection units 122 of the trigger generated by the generation unit 121ab.

Next, as shown in FIG. 7, the slave collecting unit 122 includes a control unit 122a. The control unit 122a is a controller like the control unit 121a, and is realized by, for example, executing various programs stored in the storage device inside the slave collection unit 122 by the CPU, MPU, or the like using the RAM as a work area. Will be done. Further, the control unit 122a can be realized by, for example, an integrated circuit such as an ASIC or FPGA.

The control unit 122a has an acquisition unit 122aa and a collection unit 122ab, and realizes or executes a function or operation of information processing described below.

The acquisition unit 122aa acquires the trigger notified from the master collection unit 121. The sampling unit 122ab samples the data of the vibration sensor Sr_A at high speed based on the trigger acquired by the acquisition unit 122aa.

Here, on the premise of the above description, the high-speed collection process executed by the high-speed collection unit 12 will be described in more detail. FIG. 8 is a diagram showing an example of a connection configuration of the master collection unit 121 and the slave collection unit 122. Further, FIG. 9 is a timing chart of the high-speed collection process executed by the high-speed collection unit 12.

As shown in FIG. 8, one or more slave collecting units 122 are daisy-chained to the master collecting unit 121 by, for example, a direct wire. The master collecting unit 121 grasps the communication speed using the direct line and the distances d1, d2, d3 ... For each direct line, and causes the trigger to reach each of the slave collecting units 122 at an arbitrary timing. be able to.

For example, as shown in FIG. 9, three slave collection units 122-1, 122-2, 122-3 are connected to the master collection unit 121, and the master collection unit 121 generates a trigger at _{time t n-4.} , And the notification shall be given. Then, for example, the slave collection unit 122-1 acquires a trigger at _{time t n-3.} However, the master collection unit 121 does not cause the slave collection unit 122-1 to start sampling data during the _{time t n-3.}

Similarly, for example, the slave collection unit 122-2 acquires a trigger at _{time t n-2.} However, the master collection unit 121 does not cause the slave collection unit 122-2 to start sampling data during the _{time t n-2.}

Then, for example, the slave collecting unit 122-3 acquires a trigger at _{time t n-1.} Then, based on the trigger, the master collection unit 121 causes the slave collection unit 122 to start sampling data all at once at _{a time t n} of substantially the same time as the time t _n-1.

In this way, by performing the synchronization control so that the data is collected synchronously at the same time on the time axis, the data showing the correlation between the processing units 300 at a specific time point of the production line PL is collected. can do. Further, based on this, it is possible to provide the generation device 500 with teacher data useful for generating a learning model 501 with high abnormality estimation accuracy.

Here, although the synchronization control is performed so that the data is collected synchronously at the same time on the time axis, the synchronization control may be further performed in consideration of the phase angle of the reference encoder RE.

FIG. 10 is a diagram showing the relationship between the phase angle indicated by the reference encoder RE and the sampling start timing. _{For example, it is assumed that the time t n} described with reference to FIG. 9 is the initial sampling start timing.

Then, for example, the master collecting unit 121 performs synchronous control so that data is collected when the production line PL shows a specific phase angle based on the _{time t n and the reference signal acquired from the reference encoder RE.} Can be done.

For example the master collection unit 121, as shown in FIG. 10, after the time _{t n,} at time _{t n + 1} the phase angle of the first production line PL is returned to the initial position of 0 ° from 360 °, the slave collection unit 122 Start sampling data all at once.

This makes it possible to collect data showing the correlation between the processing units 300 at a specific time point on the production line PL, which is synchronized with a predetermined position for one piece of the diaper D. Further, based on this, it is possible to provide the generation device 500 with teacher data useful for generating a learning model 501 with high abnormality estimation accuracy.

In FIG. 10, an example in which sampling is started when the phase angle of the production line PL indicates the origin position is given, but the sampling is not limited to the origin position and may be any phase angle position.

[4. Configuration example of low-speed collection unit]
Next, a configuration example of the low-speed collecting unit 13 according to the embodiment will be described with reference to FIGS. 11 and 12. First, FIG. 11 is a block diagram showing an example of the configuration of the low-speed collecting unit 13 according to the embodiment.

As shown in FIG. 11, the low-speed collection unit 13 includes a master collection unit 131 and one or more slave collection units 132 (132-1, 132-2, 132-3 ...).

The master collection unit 131 and the slave collection unit 132 can be realized by, for example, a PLC, similarly to the master collection unit 121 and the slave collection unit 122 of the high-speed collection unit 12 described above, respectively. However, here, as another example, the master collection unit 131 is realized by PLC, and the slave collection unit 132 is realized by a dedicated device specialized for data sampling.

The master collection unit 131 comprehensively controls the low-speed collection process executed by the low-speed collection unit 13. The slave collecting unit 132 samples data of, for example, the pressure sensor Sr_P among various sensors Sr connected to the plurality of processing units 300, respectively. In FIG. 11, the slave collecting unit 132 and the pressure sensor Sr_P are associated with each other in a ratio of 1: 1, but the slave collecting unit 132 and the pressure sensor Sr_P are associated with each other in a ratio of 1: n (n is a natural number). You may.

By remotely controlling each of the slave collection units 132 at a predetermined collection timing, the master collection unit 131 causes the data of the pressure sensor Sr_P to be sampled at a low speed in synchronization with the slave collection unit 132 at the same time on the time axis.

The low-speed sampling referred to here is when the rotation speed of the predetermined motor of the production line PL is equal to or higher than the predetermined value during the production of the diaper D, for example, every 30 minutes for 2 seconds, the sampling cycle is 5 milliseconds, and sampling is performed. The score is 400 points.

Further, the master collection unit 131 stores the data of the pressure sensor Sr_P sampled at low speed in each of the slave collection units 132 in the collection DB 11a.

Thereby, for example, the data of each of the pressure sensors Sr_P whose change is gradual in a short period can be sampled at a low speed with the resolution corresponding to the gradual change, and the data useful for the generation of the learning model 501 can be collected.

In FIG. 11, only the slave collecting unit 132 collects the data of the pressure sensor Sr_P, but the master collecting unit 131 together with the slave collecting unit 132 collects the data of the pressure sensor Sr_P associated with the master collecting unit 131. It may be sampled.

Further, in FIG. 11, although the pressure sensor Sr_P is taken as an example, the target of low-speed collection may be the sensor Sr that measures data that changes relatively slowly in a predetermined period, and therefore the temperature sensor Sr_T. It may be.

A configuration example of the master collection unit 131 will be described in more detail. FIG. 12 is a block diagram showing an example of the configuration of the master collection unit 131 included in the low speed collection unit 13.

As shown in FIG. 12, the master collecting unit 131 includes a control unit 131a. The control unit 131a is a controller like the control units 121a and 122a described above. For example, various programs stored in the storage device inside the master collection unit 131 are executed by the CPU, MPU, or the like using the RAM as a work area. It is realized by being done. Further, the control unit 131a can be realized by, for example, an integrated circuit such as an ASIC or FPGA.

The control unit 131a has an acquisition unit 131aa and a remote control unit 131ab, and realizes or executes an information processing function or operation described below.

The acquisition unit 131aa acquires a predetermined collection timing. The acquisition unit 131aa acquires a predetermined collection timing based on, for example, a clock signal output from a clock generation circuit (not shown) included in the collection device 10. Further, the acquisition unit 131aa acquires a reference signal indicating the phase angle of the production line PL from the reference encoder RE.

When the above-mentioned collection timing is acquired by the acquisition unit 131aa, the remote control unit 131ab remotely controls each of the slave collection units 132, which is a dedicated device specialized for data sampling, and simultaneously controls the slave collection unit 132. To start sampling data.

Further, at this time, the remote control unit 131ab collects slaves when the production line PL exhibits a specific phase angle based on the reference signal acquired by the acquisition unit 131aa, as described with reference to FIG. Data sampling can be started all at once by the unit 132.

This makes it possible to collect data showing the correlation between the processing units 300 at a specific time point on the production line PL, which is synchronized with a predetermined position for one piece of the diaper D. Further, based on this, it is possible to provide the generation device 500 with teacher data useful for generating a learning model 501 with high abnormality estimation accuracy.

In the description with reference to FIGS. 11 and 12, the low-speed collection unit 13 performs synchronous control of data collection in the same manner as the high-speed collection unit 12, but the low-speed collection unit 13 does not necessarily perform such synchronous control. You don't have to do it.

Further, in the description with reference to FIGS. 11 and 12, it was decided that the master collection unit 131 of the low-speed collection unit 13 is realized by PLC, and the slave collection unit 132 is realized by a dedicated device specialized for data sampling. However, this is not the case. For example, assuming that both the master collection unit 131 and the slave collection unit 132 are realized by PLC, the low-speed collection unit 13 has the same configuration as the high-speed collection unit 12 shown in FIGS. 5 to 10. May be good.

Further, although the synchronous control of data collection inside each of the high-speed collection unit 12 and the low-speed collection unit 13 has been described so far, the high-speed collection unit 12 and the low-speed collection unit 13 synchronize with each other to collect data. It is preferable to start. Next, such a point will be described. FIG. 13 is a timing chart of the high-speed collection process executed by the high-speed collection unit 12 and the low-speed collection process executed by the low-speed collection unit 13.

As shown in FIG. 13, the high-speed collection unit 12 and the low-speed collection unit 13 start collecting data in synchronization with each other.

The high-speed collection unit 12 and the low-speed collection unit 13 acquire a predetermined collection timing based on, for example, a clock signal output from a clock generation circuit (not shown) included in the collection device 10. Then, based on the collection timing, control is performed to synchronize the data so that the data collection is started at the same timing (in the example of FIG. 13, time t _n , t _{n + m ...).}

It should be noted that, for example, considering the delay due to the processing load, it corresponds to ACK (Acknowledgement) / NAK (Negative-Acknowledgement) or the like between the high-speed collection unit 12 and the low-speed collection unit 13 before actually starting to collect data. Timing may be synchronized by exchanging simple packets. Further, the timing may be synchronized by correcting the timing of the other with reference to either one of the high-speed collection unit 12 and the low-speed collection unit 13.

In this way, the high-speed collection unit 12 and the low-speed collection unit 13 start collecting data in synchronization with each other, so that the high-speed collection system and the low-speed collection system are included at a specific time point of the production line PL. It is possible to collect data showing the correlation between the processing units 300. Further, based on this, it is possible to provide the generation device 500 with teacher data useful for generating a learning model 501 with high abnormality estimation accuracy.

[5. Processing procedure]
Next, with reference to FIG. 14, a processing procedure executed by the collecting device 10 according to the embodiment will be described. FIG. 14 is a flowchart showing a processing procedure executed by the collecting device 10 according to the embodiment.

First, the high-speed collection unit 12 and the low-speed collection unit 13 determine whether or not the collection timing is reached (step S101). Here, if it is not the collection timing (steps S101, No), the processing from step S101 is repeated.

If the collection timing is set (step S101, Yes), the high-speed collection unit 12 collects the data of the vibration sensor Sr_A at a high speed at the first speed (step S102). At the same time, the low-speed collection unit 13 collects data other than the vibration sensor Sr_A at a low speed at a second speed lower than the first speed (step S103).

Then, the high-speed collection unit 12 and the low-speed collection unit 13 each accumulate the collected data in the collection DB 11a (step S104).

Then, the transmission unit 14 transmits the data collected by the high-speed collection unit 12 and the low-speed collection unit 13 and accumulated in the collection DB 11a to the generation device 500 of the learning model 501 for estimating the abnormality of the production line PL (step). S105). Then, the collecting device 10 repeats the process from step S101.

Up to now, as various sensors Sr, the vibration sensor Sr_A, the pressure sensor Sr_P, and the temperature sensor Sr_T have been mentioned as examples, but the types of sensors are not limited. Therefore, any sensor may be used as long as it is provided on the production line PL of the absorbent article, and for example, a tension sensor for measuring the tension of the continuous web may be used. In the case of a tension sensor, it is considered that the change in the measured value is gradual, so it may be treated as a low-speed collection system.
