The present invention relates to a process control system suitable for process control in a plating factory or the like and a program for realizing the system.

2. Description of the Related Art In recent years, there has been a demand for various industrial products to be recorded and managed for each individual product, including various processes performed in a factory, from product acceptance to processing and shipment. A process management system has been proposed for performing such recording and management without omission.

However, at sites where small-lot products are required to be processed in an extremely short delivery time, as typified by small-scale plating factories, even recording and managing each process of received products can be a big time loss. may become. At such sites, the conventional process control system, which was based on the principle of strict record keeping and management, did not fit well.

The present invention is intended to solve such problems, and an object of the present invention is to provide a process control system capable of flexible operation.

In order to solve the above problems, a process control system according to the present invention is a process control system for managing and recording processes in a factory, comprising a photographing means for photographing an image of a product received at the factory, and a photographing means for photographing an information management means for issuing a product identification number of the product to be accepted in association with the image upon receipt of the received image, and recording information in each process in the factory in association with the product identification number; Prepare.

In the present invention, the process management system has a normal mode in which information in each process is recorded in the information management means according to the progress of product processing in the factory, and a process after issuing the product identification number and before shipping the product. Information management of information in processes prior to product shipment based on information recorded at the time of shipment, without requiring information in each process to be recorded in information management means according to the progress of product processing. and a write mode for recording in the means.

A program according to the present invention causes a computer to function as information management means in the process management system.

It is a block diagram which shows the structure of a process control system. 4 is a flowchart showing procedures in normal mode; 4 is a flow chart showing a procedure of write mode;

[System configuration]
An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a process control system according to this embodiment. As shown in FIG. 1, the process control system 1 includes a server 2 and a terminal device 3 connected via a network N. A plurality of terminal devices 3 may be provided in the process control system 1 . The network N enables secure communication by VPN or the like.

The server 2 may be provided as an on-premises server device, or may be realized by so-called cloud computing provided via a network. Regardless of which form is implemented, the server 2 centrally records order information, work information, quality control information, delivery information, etc. for each product P to be managed that is input via the terminal device 3. ·to manage.

The order information may include, for example, a photograph of the product P taken at the time of receiving the product P, a receipt number, an order number, an order number, a supplier, a drawing number, a quantity, a delivery date, an order unit price, and the like. The work information may include, for example, processing details, work start date and time, work end date and time, work request form, and the like. Quality control information may include, for example, inspection results and information about defects. The delivery information may include, for example, the date and time of delivery, a statement of delivery, an invoice, other slips, and the like.

The terminal device 3 is a computer terminal equipped with a communication interface, an input/output device, a display, a storage medium, a CPU, and the like, and may be a personal computer such as a desktop type, a notebook type, a tablet type, or a portable information terminal. The terminal device 3 is arranged in each process from acceptance to shipment in the factory. A tablet-type terminal device 3 equipped with a camera may be placed in the receiving process for photographing the image of the product P. The terminal device 3 may be provided with a scanner for reading bar codes and QR codes (registered trademark) as necessary. The terminal device 3 provides input screens corresponding to information to be recorded and managed, and transmits the contents input to each input screen to the server 2 via the network N for recording.

Next, the operation of the process control system 1 configured as described above will be described. The process control system 1 has a normal mode and a light mode (simple mode).

The normal mode is a mode in which various types of information for transferring individual products are recorded in the server 2 along the flow of products in the factory from acceptance to shipment. In this normal mode, it is possible to grasp in real time which process the product has progressed to. In addition, accurate records can be kept while checking at each process.

On the other hand, the light mode is a mode that simplifies the work by omitting checks in the process and feeds back the delivery information entered when creating the shipping slip to the work information and the order information. In lite mode, information will be recorded for each individual product with a complete history at the time the shipment information is entered.

It is possible to select whether recording/management is performed in the normal mode or in the light mode for each individual product. For example, for products with extremely short delivery times, the light mode should be selected to give priority to shortening the time to shipment over recording and management, and for other products, the normal mode should give priority to accurate and timely recording and management. Operation becomes possible.

[Normal mode]
An example of a series of flow from acceptance to shipment in the normal mode will be described with reference to the flowchart shown in FIG.

In the normal mode, various information about each product is recorded in the server 2 along the product flow within the factory from acceptance to shipment. First, at the stage of receiving the product P, the product P is photographed by the camera mounted on the terminal device 3 in the receiving process, and the image is registered in the server 2 (step S100). At this stage, a product ID for the product P shown in the image is automatically issued. Subsequently, it is set (selected) to record the product P in the normal mode (step S110).

Subsequently, various order information (for example, order number, delivery date, processing content, quantity, price etc.) (step S120). Subsequently, a work request is issued from the terminal device 3 (step S130).

In the processing process, work is performed based on the work request issued in step S130. At that time, the start of work on the product P is recorded from the terminal device 3 at the start of the work (step S140), and the end of the work on the product P is recorded from the terminal device 3 at the end of the work (step S150). If there are multiple processing steps, record the start and end of each step. By referring to the information on the start and end of the work recorded in this way, the progress of the processing for the product P can be confirmed in real time. Note that the work of recording the start and end in steps S140 and S150 may include not only processing but also inspection and the like. Moreover, in step S150, not only the completion of the work but also various records (for example, inspection results, defect information, etc.) during the work may be recorded together. When the work in the processing process is completed, the shipping/delivery information is entered at the shipping window (step S160), and various slips are issued (step S170).

As described above, in the normal mode, the product P is processed while recording is performed in each process. Therefore, by referring to the information recorded in the server 2, it is possible to check the progress of the processing of the product P in real time. can.

[Light mode]
An example of a series of flow from acceptance in light mode to shipment will be described with reference to the flowchart shown in FIG.

Write mode eliminates sequential recording in the process. First, at the stage of receiving the product P, the product P is photographed by the camera mounted on the terminal device 3 in the receiving process, and the image is registered in the server 2 (step S200). At this stage, a product ID for the product P shown in the image is automatically issued. Subsequently, it is set (selected) that the product P is recorded in the write mode (step S210).

Subsequently, the work in the processing process for the product P is performed without inputting order information (step S220). At that time, the input to the terminal device 3 is also omitted regarding the start and end of the work. When the work in the processing process is completed, the shipping/delivery information is input by the terminal device 3 at the shipping window (step S230). At this time, the input shipping/delivery information is fed back to the work information and the order information, and the uninputted work information and order information are input in a form consistent with the shipping/delivery information (step S240). After inputting the shipping/delivery information, various slips are issued (step S250).

In this way, in the write mode, by omitting the recording of information at the stages of receiving orders and processing steps, it is possible to shorten the time from receiving the product P to shipping it. In addition, since various types of information are automatically fed back and recorded when shipping/delivery information is entered, consistent records can be left without much effort.

In the process control system 1 configured as described above, the product ID is automatically generated for the image of the product P, so that omissions and mistakes can be prevented. In addition, it is possible to accurately and quickly check the processing status and the past history based on the product ID. In particular, for products P recorded and managed in the normal mode, it is possible to inquire about the progress of processing in real time. Ride mode also provides flexible recording and management for products with short delivery times. Also, in light mode, it is possible to start using the system with little training at the time of installation.
