BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing control device for a rolled material, and more particularly to a control device for controlling the processing steps for a rolled material using a computer.

0002

2. Description of the Related Art Methods of manufacturing products by processing rolled material are currently being used in various fields because they are suitable for mass production of products. For example, the process of manufacturing packaging bags for food products also incorporates the process of processing the rolled material. In other words, a printing process is applied to a plain roll material called a printing material, a lamination process is applied to which another roll material is pasted, a cutting process and a bag making process are carried out.
Packaging bags are manufactured. In this way, a plurality of processing steps are normally sequentially performed on the rolled material.

0003

[Problems to be Solved by the Invention] Generally, when various types of processing are performed on a rolled material, not all parts are processed satisfactorily. Normally, machining defects occur partially. For example, in a printing process, printing defects occur, and in a laminating process, defects occur where the sheet is wrinkled. The rolled material that has undergone various processing is finally separated into individual products, but at this time, it is necessary to exclude products with defects. For this reason, work is carried out in each process to check what kind of machining defects have occurred in which parts. In other words, conventionally, a supervisor was assigned to each process to monitor the processed materials to see if there were any processing defects, and if a processing defect occurred, that fact was recorded on the quality control card. The work involves inserting a tape that indicates a processing defect into the rolled perilla material. This quality control card is sent to the next processing step together with the processed winding material. In this way, for each process, the type of processing defect occurring in which part is recorded on the quality control card. Based on the information regarding processing defects entered in this quality control card, defective products can finally be excluded.

However, in the process control using the above-mentioned quality control card, there is a problem in that it is not possible to leave sufficient control information, and therefore it is not possible to sufficiently analyze the causes of defects. In other words, in conventional process control, what kind of machining defects occur and under what conditions?
Because it is not possible to obtain detailed management information such as where and at what rate the problem occurs, statistical data cannot be obtained and sufficient analysis cannot be performed.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a processing process control device for a rolled material that can obtain sufficient control information and sufficiently analyze the causes of defects.

[0006]

[Means for Solving the Problems] (1) The first invention of the present application is a device for managing a plurality of processing steps performed on a rolled material, in which various information regarding the production machine performing the processing steps is transmitted. A terminal device that can input data is installed for each production machine, and these multiple terminal devices are connected to a host computer.The host computer centrally manages the information input to each terminal device, and the information entered into each terminal device is integrated into one terminal device. The information inputted in can be used in another terminal device, and furthermore, defect information that specifies the details and location of processing defects caused by processing by the production machine, and processing information that indicates the details of processing by the production machine. The terminal device is provided with a function for inputting information such as operation information indicating the temporal operating state of the production machine, and performance information indicating the processing performance of the production machine.

(2) A second invention of the present application is a management device according to the first invention, in which a terminal device further includes:
A function is provided for inputting next process information indicating the next process to be performed.

(3) A third invention of the present application is a management device according to the first or second invention, in which predetermined information to be attached to the processed winding material is sent to the terminal device in the form of a bar code. The device is equipped with a printer for outputting data, and a barcode reader for inputting the barcode attached to the rolled material.

[0009]

[Operation] (1) In the management device according to the first invention of the present application, from each terminal device installed for each production machine,
You can input defect information, processing information, operation information, and performance information. Since this information is centrally managed by the host computer, it is possible to obtain sufficient management information for each processing step, and it becomes possible to fully analyze the causes of defects.

(2) In the management device according to the second invention of the present application, it is further possible to input next process information from each terminal device. Therefore, for example, if processing defects occur more frequently than expected, it becomes possible to instruct a different process from the scheduled process as the next process.

(3) In the management device according to the third invention of the present application, predetermined information to be attached to the processed winding material can be output from the printer in the form of a bar code. If the output paper is attached to the roll-up material, in the next step, by reading this barcode, it can be verified whether the roll-up material is appropriate. Therefore, it is possible to prevent errors such as mixing up the winding materials between processes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on illustrative embodiments. Here, we will show an example in which the present invention is applied to the manufacturing process of food packaging bags. FIG. 1 is a diagram showing the manufacturing process of a typical food packaging bag currently being carried out. First, a winding material 1 called a printing material is prepared, and printing is applied to this through a printing process. The rolled material 2 that has undergone the printing process is laminated with other rolled materials (not shown) in a synthesis process. Furthermore, this laminated winding material 3 is
In the cutting process, it is cut into two roll-up materials 4a and 4b (normally, it is cut into more roll-up materials, but for convenience of explanation, a case where the roll-up material is cut into two is shown here). After the cutting, the rolled materials 4a, 4b are subjected to an inspection process, and then a packaging bag 5 is manufactured through a bag making process.

In each of the above-mentioned steps, the material to be wound is set on one paper feed side, the leading edge of the material is guided to the other paper discharge side, and the material to be rolled is set from the paper feed side to the paper discharge side. Predetermined machining operations are performed as the material is sent. For example, in a printing process, the rollers of a printing press are placed between the paper feed side and the paper output side. After printing is performed on the roll material pulled out from the paper feed side, it is wound up to the paper discharge side. Note that the process order shown in Figure 1 is an example of a simple model; in reality, more complex steps may be taken, such as changing the order of each process or returning to the previous process. There are many things. Here, as a simple model, we will use three printing machines in the printing process, two synthesis machines in the composition process, two cutting machines in the cutting process, two inspection machines in the inspection process, and bag making machines. In the following, we will continue to explain an example in which three bag making machines are used in the process.

A feature of this management device is that a terminal device is provided for each production machine or for each of a plurality of production machines. For example, in the printing process, three terminal devices 1 are installed in correspondence with each of the three printing machines 15 to 17.
1 to 13 are provided. FIG. 3 shows a more detailed configuration of the process department computer and terminal device. here,
The configuration of a printing process department computer 10 and a terminal device 11 connected thereto is shown. The printing process department computer 10 connected to the tap 101a of the network 101 is
Main body 10a, display device 10b, printer 10c
, and a network interface unit 10d, and in this embodiment, a general personal computer system is used for this. A terminal device 11 is connected to the tap 101b of this same network 101 via a network interface unit 11d. The terminal device 11 includes a main body 11a with a built-in display device, a printer 11b, an input device 11c, and a barcode reader 11e. The input device 11c includes a keyboard, a mouse,
A general computer input device such as a tablet can be used, or a dedicated input device on which various operation buttons are arranged can also be used. In any case,
Some input from the worker is given to the main body 11a via the input device 11c. Further, various sensors are attached to the printing press 15 to detect its operating state, and output signals from these sensors are also provided to the main body 11a.

Next, the information input to the terminal device 11 will be explained in detail. The terminal device 11 of this embodiment includes FIG.
Various information shown in is given to the terminal device 11. below,
This will be explained in order.

(A) Defect Information Defect information A is information that specifies the content and location of a processing defect that has occurred in the processing process of a production machine such as the printing press 15. For example, in the printing process department, the details of processing defects (
For example, the printing machine 15
The worker in charge of the information can input the information using the input device 11c. In the apparatus of this embodiment, a menu of various machining defect details is displayed on the display of the main body 11a, and the operator inputs the machining defect details by selecting the desired content on this display. be able to. The position of the processing defect can be easily input by referring to the sensor output provided in the printing machine 15. That is, in the printing machine 15, the rolled material drawn out from the paper feed side is wound up to the paper discharge side after printing is performed. Therefore, by attaching a sensor that counts the amount of paper pulled out from the paper feed side or the amount of paper rolled up to the paper ejection side, the position where printing is currently being performed can be captured as an output signal from this sensor. When the operator discovers a processing defect while monitoring the printing process, the operator inputs a detection signal indicating the detection of the processing defect from the input device 11c (preferably, a device equipped with a dedicated operation button is prepared as the input device 11c). , which improves the usability of this input operation). When this discovery signal is given, information indicating the location of the machining defect can be obtained by referring to the output signal from the sensor. In general, processing defects in printing often continue to appear for a certain period of time. Therefore, it is preferable to be able to specify a defect start position and a defect end position as positions of machining defects.

(B) Processing Information Processing information B is information indicating the content of processing by the production machine. For example, in the case of the printing machine 15, the pitch of a printing pattern, etc. can be input as processing information. The embodiment described here is a manufacturing process for packaging bags for food products, but as shown in FIG. In the process, the printing pattern of one packaging bag is repeatedly printed at a predetermined pitch. Normally, this pitch is actually measured after the printing process is completed. In the apparatus of this embodiment, the worker inputs the actually measured pitch data from the input device 11c. In addition,
For example, in a terminal device in a synthesis process department, information regarding the adhesive used in lamination processing can be inputted as processing information. In addition, in this synthesis process department,
Lamination processing is performed by attaching multiple sheets to multiple units and pasting each sheet together, but information indicating the relationship between the unit and the sheet, such as which sheet is attached to which unit, is used as processing information. You could also enter it.

(C) Operation Information Operation information C is information indicating the temporal operation state of a production machine such as the printing press 15. In this embodiment, based on the signals of the sensors attached to the production machine, it is possible to determine whether the machine is in an operating state, a ready state, a dormant state, or an inhibited state (some fault has occurred and the machine is not in operation). The system is configured so that it can be determined whether the system is in a suspended state), and operating information is automatically entered without waiting for input operations by a worker. As a result, the temporal operating status of each production machine is recorded. In addition, in this embodiment, the configuration is such that the inhibiting factor in the inhibiting state and the name of the worker in charge can also be input. That is, while looking at the display screen of the terminal device main body 11a, the worker can touch the screen to input the inhibiting factor, the name of the worker in charge, and the like. Further, it is convenient to be able to display a time chart showing operation information of the production machine on this display screen.

(D) Performance Information Performance information D is information indicating the processing performance of production machines such as the printing press 15. Specifically, it is information that shows actual results, such as how much processing was performed, how much of it was an effective amount without defects, how much was defective, and how many defective parts were present. . For example, the performance in the printing process can be obtained based on data indicating the amount of processing given from the printing machine 15 and data regarding processing defects input from the input device 11c. The performance information obtained in this way can be displayed on the display screen of the terminal device main body 11a. In this embodiment, results can be displayed in two ways: results for each item and results for each fabric. The results for each item are, for example,
This is information indicating the total processed amount, effective amount, defective amount, and number of defective items for each item, such as an item called a packaging bag for X ramen noodles and an item called a packaging bag for Y ramen noodles. When a plurality of raw fabrics are used for one item, the cumulative value may be calculated based on these values for each raw fabric. For example,
The performance display for the item ramen packaging bags is as follows. (Rolling material code) (Total processing amount) (Effective amount)
(Amount of defects) (Number of defects) 0001
400m 380m 2
0m 2 places 0002
400m 350m 50m
4 locations 0003
250m 240m 10m
1 location cumulative total
1050m 970m 80m
The seven examples listed above are results for each item. The results for each raw fabric indicate the results only for a specific raw fabric. For example, in the example above, only 250 m of the raw material indicated by the winding material code 0003 is processed to be used as a packaging bag for X ramen noodles, and the remaining 150 m is processed as a packaging bag for another item, Y ramen noodles. In some cases, it appears to have been processed. In the performance display for each raw fabric, the performance for a specific raw fabric is displayed.

(E) Next process information In the packaging bag manufacturing process shown in this embodiment, each process is executed in the order shown in FIG. Process control of each winding material is performed by the host computer 100. Therefore, after one process is completed, the host computer 100 can instruct which process is the next process. However, if an extremely large number of processing defects occur in a certain process, it may be appropriate to change the schedule for the next process. In such a case, the worker can input information to change the next process by touching the display screen. For example, if an extremely large number of printing defects occur in the printing process, if the planned composition process is performed using a roll material containing many such printing defects, it will be difficult to remove the defective parts later. This results in a large amount of waste. Therefore, it is preferable to perform a process of removing defective portions (so-called reversal inspection process) before performing the synthesis process. Such process changes can be made by the operator inputting information to change the next process. Note that, as will be described later, after one process is completed, information indicating the next process is output from the printer 11b and attached to the rolled material.

(F) Barcode information As mentioned above,
The terminal device 11 is provided with a printer 11b. In the apparatus of this embodiment, when a certain processing step is completed, information indicating the order number, the winding material code, the current process in which processing has been completed, and the next process described above regarding the processed winding material is displayed in the bar. It is output in code format. The operator attaches the output paper containing this barcode information to the processed winding material. Therefore, in the next process, the winding material is delivered together with the barcode information attached in the previous process. When the winding material is delivered, the operator first reads the barcode information using the barcode reader 11e. In other words, the order number, the winding material code, the previous process (barcode output as "current process" in the previous process), and the current process (barcode output as "next process" in the previous process) related to the winding material. information) is entered. The terminal device inquires this content to the host computer 100 and downloads the management information regarding this winding material. If the operator mixes up the winding material, this error will be discovered when the host computer 100 is contacted. In this way, by attaching barcode information to each winding material, it is possible to prevent mistakes such as mixing up the winding materials. Generally, when processing a rolled material, after one processing step is completed, the rolled material is often stored in a warehouse or the like for a while before executing the next processing step. Therefore, preventing mistakes in mixing up the winding materials using the above-described method greatly contributes to improving productivity.

The information A to F input into the terminal device of this embodiment has been described above in detail. All of this information is centrally managed in the host computer 100. In particular, defect information A, processing information B, operation information C, and performance information D can provide sufficient clues to analyze the cause of defect occurrence. In other words, defect information A shows what kind of machining defects occurred in the past and at what locations.
It is possible to recognize from the processing information B what kind of processing conditions the production machine was operating at that time, and it is possible to recognize from the operation information C what kind of operating conditions the production machine was operating at that time. As a result, it is possible to recognize from the performance information D how much performance has been obtained.

Although the present invention has been described above based on the illustrated embodiment, the present invention is not limited to this embodiment, and can be implemented in various other ways. In particular, the device configurations shown in FIGS. 2 and 3 are shown as examples, and any actual hardware configuration may be used.
