Next, an example of the operation of the packaging device as the product data processing device will be described with reference to FIGS. 8, 9, 15, 16, and the like.

In step ST1, the control unit 52 initializes various parameters, for example, as initial processing. In addition, the state of each drive unit (detection signal (data) by the drive detection unit) when the drive unit is normally attached or when the drive unit is first attached is stored in the storage unit in advance. Further, if necessary, the detection signal (data) of the drive detection unit corresponding to each drive unit is subjected to a Fourier transform such as FFT, and the frequency spectrum calculated by the Fourier transform is stored in the storage unit.
The control unit 52 may transmit a detection signal (data) or the like indicating the state of each drive unit to the management server, and the management server may store the state of each drive unit.

In step ST2, the control unit 52 performs an operation of packaging the object to be packaged according to a predetermined step in the normal mode (normal operation mode).

In step ST3, the drive detection unit 90 detects the state of the drive unit and outputs a detection signal (data) to the control unit 52.

In step ST4, the control unit 52 performs a Fourier transform such as FFT on the detection signal (data) based on the detection signal by the drive detection unit 90 corresponding to each drive unit 80, and is calculated by the Fourier transform. A process of comparing the frequency spectrum (see, for example, FIG. 8A) with the normal frequency spectrum (see, for example, FIG. 8B) read from the storage unit is performed.

In step ST5, the control unit 52 determines whether or not the state detected by the drive detection unit is within the normal range.
Specifically, for example, the frequency spectrum intensity of the vibration acceleration of the storage unit corresponding to each drive unit is compared with the frequency spectrum intensity at the normal time, and for example, when the intensity above the specified frequency is within the threshold value, it is normal. If the intensity above the specified frequency exceeds the threshold value, it is determined that the frequency is out of the normal range, and the process proceeds to step ST7.

In step ST6, the control unit 52 operates in the normal mode, and proceeds to the process of step ST3 as necessary.

In step ST7, the notification unit (notification means) of the control unit 52 notifies maintenance information indicating the result of determining whether or not maintenance is necessary for the drive unit. Specifically, a notification process for warning that maintenance is necessary is performed. Do.
Further, as the notification process, the control unit 52 may notify the fact from, for example, a speaker provided in the packaging device or a display device of the display operation unit, or the packaging device 100 notifies the management server 500 to that effect. To do. When the management server 500 receives maintenance information from the packaging device 100 that requires maintenance of the drive unit, it requests, for example, a maintenance engineer (repair company) or the like for emergency maintenance. Specifically, a computer (not shown) managed by a maintenance engineer (repair company) is contacted via a communication path (network NT, etc.). Further, when the maintenance engineer receives information such as the estimated time of arrival (or the time required for arrival) at the installation location of the packaging device from the computer managed by the maintenance engineer, the management server 500 receives the estimated time of arrival information (or arrival). Time required for) is transmitted to the packaging device 100. Then, the packaging device performs a process of displaying the estimated arrival time information (or the time required for arrival) on the display unit of the display operation unit 39.

That is, the control unit 52 can detect an abnormal state of the drive unit 80 at an early stage and notify that maintenance is required before the drive unit 80 completely fails.
When the control unit 52 receives a signal (error signal) indicating that the drive unit 80 has completely failed, or receives no signal from the drive unit 80, for example, the drive unit 80 has completely failed. Performs notification processing to notify that the operation has been performed.

Further, in step ST8, the control unit 52 sets the limit mode (restricted operation mode) that limits the function of the drive unit 80, or continues the normal mode (normal operation mode) as it is, and the display operation unit 39 provides candidates. Performs a process of displaying on (touch panel, etc.) so that it can be selected by the operator.

In step ST9, by the operation of selecting the restricted mode or the normal mode by the operator, the display operation unit 39 (touch panel or the like) outputs a signal indicating the selected restricted mode or the normal mode to the control unit 52.
The product data processing device such as a packaging device may have a configuration in which the above-mentioned candidates can be selected by voice input by adopting voice recognition technology or the like.

When the restriction mode is selected in step ST10, the control unit 52 operates the drive unit 80 in the abnormal state (abnormal state) in the restriction mode. The limiting mode is, for example, an operation mode in which the load on the drive unit 80 is smaller than that of the normal operation mode (normal mode). Further, for example, the processing speed of the drive unit 80 is lowered as compared with the normal mode.
When the normal mode is selected, the control unit 52 operates the drive unit 80 in the normal mode. For example, the operator selects the normal mode when he / she wants to prioritize the processing speed rather than reducing the load on the drive unit 80 in consideration of the remaining number of processes (the number of the remaining items to be packaged) and the like.

Next, an example of detection by the drive detection unit will be described with reference to FIG.
Specifically, first, the acceleration of vibration in each axial direction of the drive unit 80 is measured by an acceleration sensor as a drive detection unit.
Next, in each axial direction, the signal (measurement data) indicating the measured vibration acceleration is subjected to FFT processing, and the vibration spectrum is calculated. FIG. 8A shows an example of a vibration spectrum in the Y-axis direction (also referred to as a frequency spectrum of vibration acceleration). In the example shown in FIG. 8A, the drive unit is in an abnormal state.

As shown in FIG. 8B, when the drive unit is normal, the vibration spectrum (frequency spectrum of vibration acceleration) corresponding to the signal measured by the drive detection unit is calculated in advance.

Then, the control unit calculates the difference between the vibration spectrum obtained by the drive detection unit (see FIG. 8A) and the normal vibration spectrum (see FIG. 8B). The magnitude of the amplitude of the difference vibration spectrum (see FIG. 8C) is evaluated, and if it is within a predetermined range, it operates in the normal mode, and if it is outside the predetermined range, it is determined that the drive unit is in an abnormal state. , Warns (alerts) and operates the drive unit in restricted mode.
As an evaluation of the magnitude of the amplitude of the vibration spectrum (see FIG. 8 (c)), for example, the spectral intensity of the specified frequency (about 170 Hz) or higher is the amplitude in the example shown in FIG. 8 (c). 20) In the above cases, the control unit determines that the drive unit is in an abnormal state, issues a warning (alert), and operates the drive unit in the restricted mode.

As described above, the packaging device 100 as the product data processing device according to the embodiment of the present invention includes the drive unit 80 (the drive motor (elevator motor, carry-in motor, film transfer motor, etc.) of the packaging unit, and the suction unit. (Drive motor, drive motor of printing unit, etc.), drive detection unit 90 that detects the state of the drive unit, and notification of maintenance information that indicates the judgment result of the necessity of maintenance related to the drive unit according to the detection by the drive detection unit 90. It has a notification unit 522, etc. that performs processing.
That is, it is possible to provide a product data processing device such as a packaging device capable of detecting an abnormal state of the drive unit 80 at an early stage and performing notification before the drive unit 80 fails with a simple configuration.

Further, the packaging device 100 as the product data processing device according to the embodiment of the present invention has a limit control unit 523 that limits the function of the drive unit 80 determined to require maintenance.
That is, a packaging device or the like that can detect an abnormal state of the drive unit 80 at an early stage before the drive unit 80 breaks down, and the restriction control unit 523 can limit the functions of the drive unit 80 that is determined to require maintenance. Product data processing device can be provided.
Further, in detail, the restriction control unit 523 performs a process of limiting the operation mode of the drive unit determined to require maintenance depending on the state of the drive unit 80.
For example, the limit control unit 523 operates in a limit operation mode (also referred to as a limit mode), which is an operation mode in which the load on the drive unit 80 is smaller than that of the normal operation mode (also referred to as the normal mode).
In the limited operation mode, for example, the operation speed of the drive unit 80 is set to be lower than that of the normal mode, and processing is performed to reduce the load on the drive unit 80.
The limited operation mode is not limited to this embodiment, and may be any operation that reduces the load on the drive unit. For example, by changing the high-precision operation mode to the low-precision operation mode, the drive unit is loaded. May be reduced. Setting the high-precision operation mode to the low-precision operation mode means, for example, in the case of a label affixing device, the load on the affixing device is reduced by increasing the error of the affixing position where the label is affixed.

Further, the restriction control unit 523 of the packaging device 100 as the product data processing device according to the embodiment of the present invention controls the magnitude of the function restriction of the drive unit 80 based on the detection result by the drive detection unit 90.
Specifically, for example, the degree of deterioration of the drive unit 80 is determined based on the signal from the drive detection unit 90, and as a result of the determination, the greater the deterioration, the greater the limitation on the function of the drive unit 80. Specifically, for example, by further reducing the operation of the drive unit 80, the load on the drive unit 80 is further reduced.
That is, the degree of deterioration of the drive unit 80 is determined based on the signal from the drive detection unit 90, and as a result of the determination, the smaller the deterioration, the smaller the restriction on the function of the drive unit 80. For example, by further making the operation of the drive unit 80 slightly slower than usual, it is possible to reduce the load on the drive unit 80 while suppressing a significant decrease in the efficiency of the drive unit 80.

Further, the restriction control unit 523 of the packaging device 100 as the product data processing device according to the embodiment of the present invention changes the content of the restriction on the drive unit 80 based on the time information until the maintenance is performed.
For example, the control unit 52 of the packaging device as a product data processing device sends information about a drive unit that requires maintenance to, for example, a management server 500 (management computer) via a communication unit, for example, replacement of parts of the drive unit. Send information such as is required.
When the management server 500 receives, for example, information on the maintenance of the drive unit from the packaging device, the management server 500 makes a request to a repair company (maintenance company) that performs maintenance on the drive unit of the packaging device based on the information. The scheduled repair time from the arrival of the repair company to the start of maintenance work such as parts replacement is transmitted to the packaging device 100 as the time information.
When the packaging device 100 receives the above-mentioned time information regarding maintenance from the management server 500, the packaging device 100 stores the time information until the maintenance is performed in the storage unit.
Further, the time information until the maintenance is performed is not limited to the above-described embodiment, and for example, the storage unit of the packaging device may store the average time information in advance.
The average time information may be stored in the storage unit of the packaging device 100 from the management server 500 via the communication unit.

Further, the drive detection unit of the packaging device 100 as the product data processing device according to the embodiment of the present invention is provided so as to be able to detect the states of a plurality of drive units, and the drive unit in the drive state in each process of the product data processing device. The state of the drive unit in the drive state is detected according to the vibration from the chisel.
Specifically, for example, when an acceleration sensor is adopted as the drive detection unit, the acceleration sensor is arranged at a position where vibration of a plurality of drive units can be measured.
For example, a case where one acceleration sensor capable of measuring vibrations from each of a plurality of drive units is provided will be described.

In the plurality of drive units, the drive unit in the driven state or the drive unit in the non-drive state is different in each step of the operation of the device.
Specifically, for example, in the process of carrying in the packaged object, the drive motor (drive unit) of the carry-in unit is in the drive state, and other drive motors (drive unit) for folding the film, for example, are in the non-drive state. Is. Further, in the process of stretching the film, the drive motor (drive unit) of the drive mechanism for film tensioning is in the drive state, and other, for example, the drive motor (drive unit) of the carry-in portion is in the non-drive state. , The drive motor (drive unit) for folding the film is in a non-drive state.
That is, the drive detection unit measures the vibration by the drive unit in the drive state in each process, and does not detect the vibration because the vibration is not generated from the drive unit in the non-drive state.
That is, even if the acceleration sensor of the drive detection unit is arranged at a position where vibration from each of the plurality of drive units can be detected, the timing at which the vibration of each drive unit is generated is different for each process. By measuring the vibration from only the drive unit in the drive state specified for each process, the state of the drive unit in the drive state can be detected with high accuracy.

Further, as compared with a device (comparative example) in which a drive detection unit is provided for each of the plurality of drive units, the packaging device as the product data processing device according to the present invention uses a smaller number of drive detection units to provide each drive unit.

Specifically, for example, when the frequency spectrum intensity of a predetermined frequency (for example, 170 Hz) or higher is equal to or higher than the threshold value, it is determined that maintenance is required, and the notification unit 522 notifies the maintenance information indicating that fact. I do.
The predetermined frequency is, for example, a frequency obtained by comparing the normal state and the abnormal state (abnormal state) of the drive unit and when vibration acceleration in a high frequency band occurs in the abnormal state (abnormal state). It is desirable to specify the lower limit frequency of the band or a frequency near it.
That is, it is possible to provide a product data processing device that easily detects an abnormal state (abnormal state) with a simple configuration.

Further, the notification unit 522 of the packaging device 100 as the product data processing device according to the embodiment of the present invention has a frequency spectrum of vibration based on the acceleration signal detected by the acceleration detection unit of the drive detection unit 90 and a storage unit. Based on the stored difference from the normal frequency spectrum, a process of notifying maintenance information indicating the result of determining whether or not maintenance is necessary for the drive unit 80 is performed.
Specifically, the notification unit 522 performs a Fourier transform process (for example, FFT (Fast Fourier Transform process)) on the acceleration signal (acceleration data) of the vibration measured by the drive detection unit 90 to calculate a frequency spectrum. The difference between the calculated frequency spectrum and the normal frequency spectrum is evaluated, and when the amplitude of the difference (frequency spectrum intensity) is larger than the predetermined threshold value, or the difference amplitude (frequency spectrum intensity) is predetermined. When a frequency (for example, 170 Hz) or higher is higher than a predetermined threshold value, it is determined that the frequency is abnormal (abnormal state), and a process of notifying maintenance information indicating that fact is performed.

Further, the packaging device 100 as a product data processing device according to the embodiment of the present invention has a label attaching portion for attaching a label to a product packaged by a packaging portion (packaging mechanism), and the label attaching portion bears a label. It has a suction unit that can be attracted by pressure, a fan that generates negative pressure, and a fan drive motor (drive unit). The drive detection unit 90 measures the suction time of the label to the suction unit, and when it exceeds the set threshold value, the notification unit performs an alarm (alert) process.
With a simple configuration, the packaging device can easily detect the state of the fan drive motor (drive unit) of the label sticking portion, and can perform a process of notifying maintenance information based on the detection result.

Further, the notification unit 522 of the packaging device 100 as a product data processing device indicates the result of determination of the necessity of maintenance of the drive unit 80 based on the result of detection by the drive detection unit 90 and the drive history of the drive unit 80.

May be used.
That is, it is possible to determine the necessity of maintenance based on the drive history (drive log, etc.) of the drive unit stored in the storage unit or the like and the detection result of the current status of the drive unit.

Further, the notification unit 522 of the packaging device 100 as the product data processing device according to the embodiment of the present invention is, for example, the fragility of the drive unit 80, the importance of the drive unit 80, or the time required for replacement of the drive unit 80.

An example of the priority of the importance of the drive unit 80 will be described.
The priority of the importance of the drive unit 80 is, for example, that when the label affixing part breaks down, the operator can manually affix the label by switching from the automatic label affixing mode to the manual label affixing mode. Urgent maintenance is set as a low priority.
At the time of packaging, the packaging device cannot replace the drive motor (drive unit) for folding the film of the packaging unit (packaging means), so that the priority for urgent maintenance is set to be high.

That is, in the above-described example, the maintenance information regarding the drive motor (drive unit) of the packaging unit is notified as having a higher priority than the drive motor (drive unit) of the label sticking portion.

The priority of the drive unit is not limited to the above-described embodiment, and the priority may be defined from another viewpoint.
