Description

data management system

The present invention relates to a system (system) for storing and managing data related to the operation of production-related equipment.

Historically, various production-related devices have been used at the manufacturing site of WIP. For example, in the production line (line) of blister sheets (such as PTP (Press Through Package) sheets) generally used in the fields of pharmaceuticals and food, blister sheets are used in terms of production-related devices. Packaging machines, stacking devices and packaging devices, etc. Blister packaging machine is equipped with a means of forming a pocket portion on a container film (film), a means of accommodating contents (such as tablets) in the pocket portion, and a means of attaching a cover film to the container film etc., and manufacture blister sheets. The stacking device stacks the manufactured blister sheets in units of a plurality of sheets. The packaging device is used to process the stacked blister sheets, for example, banding, pillow packaging, and box packing. In addition, in the blister packaging machine and packaging equipment system, an inspection device for judging the quality of the contents, sheets, packaging, etc. is provided. Such inspection devices may also be referred to as production-related devices.

In addition, when an abnormality of a product is found during production, from the viewpoint of preventing recurrence, etc., the problematic process, the timing of the occurrence of the abnormality, the number of manufactured abnormal products, and various setting information related to manufacturing (such as , temperature and pressure, etc.) etc. In order to conduct such investigations, it is necessary to store various materials related to manufacturing and the like. Here, in consideration of easiness of investigation, etc., it is preferable to store the data in the form of electronic data. However, since electronic data is easy to change and delete, measures must be taken to ensure the integrity of the information.

A guideline (ALCOA principle) prescribed by FDA (Food and Drug Administration; U.S. Food and Drug Administration) is known as a guideline for ensuring data integrity and the like. The ALCOA principles stipulate 5 elements. The first element is traceability (Attributable), the second element is clarity (Legible), the third element is synchronous (Contemporaneous), the fourth element is original (Original), and the fifth element is correctness (Accurate) . Here, the so-called synchronicity refers to memorizing in real time when the data is generated (when the processing is executed). In order to satisfy the synchronicity, it is necessary to memorize the time when the data is generated.

In recent years, in order to strictly observe the above-mentioned third requirement (synchronization), a system has been proposed that includes control processing means (processing means), data storage server (server computer), network (information connection means) and drive restriction means, when the control processing means, network or data storage server are not functioning, restrict the drive of the device (such as the above-mentioned production-related devices), and only memorize the data together with the time of occurrence to the data storage server (Refer, for example, to the following Patent Document 1, etc.).

In this system, the control processing means performs control processing related to the operation of the device, and the network performs information transfer between the control processing means and the data storage server. In addition, the processing application for driving the device is stored in the control processing means, and the setting information for executing the processing application is stored in the data storage server. Therefore, when there is an abnormality in the network or the data storage server, the control processing means can no longer read the setting information from the data storage server, and the drive (specifically, startup) of the device is restricted. In this way, when there is an abnormality in the network, the data storage server, and the control processing means, the data that should be memorized will no longer be generated. As a result, the data stored in the data storage server together with the time will meet the synchronization requirements and have no gaps. data of. [Prior Art Literature] [Patent Document]

[Problem to be solved by the invention]

However, in the above-mentioned system, once the device is activated, when the data storage server and the network are abnormal, the data cannot be stored in the data storage server. Therefore, although it is conceivable to temporarily stop the device when an abnormality occurs, the device cannot be stopped because the data related to the stop of the device cannot be stored in the data storage server. On the other hand, even if the device is intended to continue to operate, the device cannot be continued to operate because the data in operation cannot be stored in the data storage server.

The present invention was developed in view of the above-mentioned circumstances, and aims to provide a data management system that can still store data even if an abnormality occurs in the data storage server and the network, and can more strictly satisfy the synchronization requirement in the stored data.

In addition, the processing determination device 140 stops the inspection device 70 in conjunction with the stop of the PTP packaging machine 10 and the packaging device 60 .

In the situation where the above-mentioned network 110 and data storage server 120 do not function normally, when production and inspection continue, the local memory unit 160 also continues to store data and data generation time information. In addition, when the PTP packaging machine 10 and the inspection device 70 stop, the data related to the stop and the time information of the data generation are stored in the local memory unit 160 . In addition, the stored data and the like are sent to the data storage server 120 through the network 110 when the network 110 and the data storage server 120 recover and function normally.

Therefore, it is possible to prevent the PTP packaging machine 10 and the like from starting in a state where data cannot be stored in the data storage server 120 , and it is possible to more reliably ensure the integrity of the data stored in the data storage server 120 .

In addition, the data and data generation time information are stored in the local memory 160 before being sent to the data storage server 120, so even if the data storage server 120 and the network 110 are abnormal, the data can still be stored. Therefore, if an abnormality occurs in the data storage server 120 or the network 110, the operation of the PTP packaging machine 10 and the like can be continued and the data in operation can be memorized, and the PTP packaging machine 10 and the like can be stopped and the data related to the stop can be memorized. Therefore, when an abnormality occurs in the data storage server 120 or the network 110, there will be no suspense related to the memory of the data, etc., and the operation of the PTP packaging machine 10 and the like can be appropriately selected to continue or stop.

In addition, since data and the like are stored in the local storage unit 160, it is possible to more reliably prevent the disappearance of data due to an abnormality in the data storage server 120 or the network 110. As a result, the integrity of the data stored in the data storage server 120 can be guaranteed more reliably.

In addition, each control device 130 etc. corrects the time of the local clock unit 150 based on the reference time information sent from the reference time generation unit 122 through the network 110 . Therefore, the times indicated by the plurality of local clock units 150 can be roughly aligned, and each control device 130 can obtain the generation time of the data using a unified reference (reference time). Thereby, the generation time of the data stored in the data storage server 120 (main storage unit 121 ) can be made more accurate. As a result, the data stored in the data storage server 120 can more strictly satisfy the synchronization requirements.

In addition, each control device 130 can start the corresponding PTP packaging machine 10, inspection device 70, etc. after correcting the time of the local clock unit 150 based on the reference time signal. Therefore, when starting up the PTP packaging machine 10 etc., the time of each local clock unit 150 can be aligned with the reference time, and the data stored in the data storage server 120 can further satisfy the synchronization requirements more strictly.

Furthermore, each control device 130 cannot start the corresponding PTP packaging machine 10, inspection device 70, etc. unless the time of the clock unit 150 of the machine is corrected for a predetermined period or more. Therefore, when there is a possibility that the time of the local clock unit 150 deviates greatly from the reference time, the PTP packaging machine 10 cannot be started, and it is even possible to avoid memorizing data related to the operation of the PTP packaging machine 10 and the like. Therefore, the data stored in the data storage server 120 (main storage unit 121 ) can further more strictly satisfy the synchronization requirements.

In addition, in the present embodiment, the data storage server 120 includes a reference time generation unit 122 . Therefore, each control device 130 and the like can confirm that the data storage server 120 and the network 110 are functioning (normally) by receiving the reference time signal. Therefore, the reception of the reference time signal is also confirmed that the data storage server 120 and the network 110 are functioning, and each control device 130 does not need to perform special operations for this confirmation. Therefore, it is possible to reduce the processing load on each control device 130 and the like.

In addition, the data storage server 120 can compare the reference time indicated by the reference time generator 122 when receiving the transmission time information with the time based on the transmission time information. Thereby, it is possible to grasp whether each of the time indicated by each local clock unit 150 is appropriate, and to perform a response based on the result of the grasp.

In addition, the control device 130 for performing control processing related to the PTP packaging machine 10 is to continue the operation of the PTP packaging machine 10 until at least the data storage server 120 and/or the network 110 is not functioning. 20 lozenges until 5 are used up. Therefore, it is possible to prevent the tablet 5 from being left in the storage device 20 for a long time, and it is possible to more reliably prevent the tablet 5 from being discarded in vain.
