Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame number management apparatus suitable for use in managing the embossing of a frame number in, for example, an automobile production line.

2. Description of the Related Art In an automobile production line, a serial number is imprinted on a frame to identify a vehicle to be produced. This serial number is generally called a frame number, and is used not only for identification of a vehicle at the time of production but also for various registrations and quality control after the product is manufactured.

The frame number is stamped on each frame according to the production plan, and it is necessary to take care not to perform double stamping at this stamping. That is, if the same number is duplicatedly stamped, the identification function as the frame number is lost, and various problems arise in management. Therefore, conventionally, an operator performing embossing refers to a checklist or the like, and confirms this visually or the like.

[Problem to be Solved by the Invention] By the way, the frame number to be embossed is instructed from the main computer to each production line based on the production plan. Here, the designated frame number data is data for one week. This is because the production line generally sets the number of production units on a weekly basis. On the other hand, since a production plan is usually made on a monthly basis, one month's worth of frame number data is prepared in the main computer. Therefore, the main computer divides the frame number data for one month into week units, and instructs the divided data to the production line every week.

However, the above-described conventional checking method is insufficient for checking double numbering or missing numbers that occur due to an operation error on the main computer side or an error during setting.

In addition, since the current production line adopts a form in which different models are mixed and produced, it is necessary to set a continuous frame number for each vehicle section. There is a drawback that a huge number of man-hours are required and that a check error is likely to occur.

The present invention has been made in view of the above circumstances, and provides a frame number management device capable of automatically checking the continuity of frame number data and setting a continuous frame number for each vehicle section. It is intended to be.

[Means for Solving the Problems] According to the present invention, as shown in FIG. 1, communication for receiving frame number data including the number of stamps for each vehicle section and the starting frame number for starting stamping. Control means a, storage means b for storing data received via said communication control means a, a data table c in which the last frame number for each vehicle section is registered, and a first frame extracted from said storage means b The first frame number is compared with the last frame number for each vehicle section, and if the first frame number is smaller than the last frame number, it is determined that double numbering is performed. If it is the next number, determination means d for determining that it is a serial number
If it is determined by the determination means d that the numbering is double, an error is displayed. If it is determined that the numbering is sequential, a new final number obtained from the starting frame number and the number of stamps is obtained. A controller e for registering a frame number in the data table c.

According to the present invention, the determination means d compares the first frame number and the last frame number for each vehicle section, and if the first frame number is a number smaller than the last frame number, double numbering is performed. On the other hand, if the starting frame number is a number next to the last frame number, it is determined that the frame number is a serial number. If the determination result is a double numbering, the control means e displays an error. On the other hand, if the determination result is a serial number, a new final frame number obtained from the starting frame number and the number of stamps is displayed. To the data table c
To be registered.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 is a block diagram showing the overall configuration of one embodiment of the present invention. In this figure, reference numeral 1 denotes an embossing machine for embossing a frame number. When an operator sets a frame member and operates a predetermined button, the frame number is automatically embossed. An operation panel 2 gives various commands and a frame number to be stamped to the stamping machine 1. In addition, the embossing machine 1
When the embossing of the units is completed, a completion signal is output to the operation panel 2. Reference numeral 3 denotes a control panel, which supplies various data to the operation panel 2. The control panel 3 includes a machine controller 5 and a data control section 6, and data is exchanged between them. Further, the machine controller 5 and the data control section 6 exchange data with the host computer 8, respectively. The host computer 8 supplies the processing order data Da for one week based on the production plan to the data control unit 6.

Here, the format of the processing order data Da will be described with reference to FIG. In this figure, F1 to F11 are fields, and among these fields F1 to F11, for example, F3 is a processing order of a vehicle to be processed, F4 is a vehicle model, F7 is a lot number, and F8 is a destination. Series indicating the ground,
In F9, a frame number at which embossing is started, and in F11, data for distinguishing the attribute of this record are set. One field of the processing order data Da is formed by these fields F1 to F11, and a required number of records are accumulated to form the processing order data Da for one week.

Next, returning to FIG. 2, the overall configuration of the embodiment will be described again. The data control unit 6 to which the processing order data Da is supplied performs various processes for confirming the continuity of the data Da, and supplies the frame number data obtained thereby to the machine controller 5. . The data processing in the data control unit 6 will be described later. The machine controller 5 outputs the frame number data supplied from the data control unit 6 to the operation panel 2 together with a signal for controlling the embossing machine 1. Further, the machine controller 5 rearranges the frame numbers based on the ratio setting data Dr supplied from the host computer 8. The ratio setting data Dr is data indicating the production ratio of the models in the case of performing mixed production of different models. The reason for changing the frame number is that when different models are mixed and produced at a predetermined ratio, the quality of production is determined by the way of mixing each model, so that the best efficiency is obtained. That's why. For example, if model A and model B are to be produced at a 3: 2 ratio, A → B → A →
Efficiency is good if produced in the pattern of A → B. Here, since the frame numbers to be stamped are consecutive numbers for each model, it is necessary to rearrange according to the pattern.

Next, the configuration of the data control unit 6 will be described with reference to FIG. In this figure, 10 controls each part of the circuit
A CPU 11 is a ROM in which programs and the like are stored, and 12 is a RAM in which various data are temporarily stored. This RAM12 is 5th
As shown in the figure, a plurality of files formed from a predetermined storage area are configured. This file includes a processing order file 12a for storing the processing order data Da and a work file 12 for temporarily storing the received processing order data Da.
b, there is a check file 12c and a stamping master file 12d to be described later. Reference numeral 13 denotes a communication interface, which controls transmission and reception of data to and from the host computer 8 and the machine controller 5. Reference numeral 14 denotes an operation unit including a keyboard and the like, which issues various commands to the CPU 10. 15 is CPU
This is a display controller that controls the display of the CRT 16 under the control of 10.

Next, the check file 12c and the embossed master file 12d described above with reference to FIGS. 6 and 7 will be described. FIG. 6 is a diagram showing the concept of the check file 12c. This check file 12c is, for example,
Vehicles are divided by dividing each of A, B, and C into destinations S1, S2, and S3, and a data table is stored in which the last frame number for each of these vehicle divisions is stored. Next, FIG. 7 is a view showing the concept of the embossing master file 12e. The embossing master file 12e constitutes a data table, in which field data (F1 to F8, F10, F11) for each vehicle corresponding to the frame number is stored. The frame numbers are developed in numerical order by the processing described later.

Next, the operation of the embodiment having the above configuration will be described.

(1) Reception operation of processing order data Da First, when communication between the host computer 8 and the data control unit 6 is established according to a predetermined communication procedure, first, the processing order data Da for one week is transmitted from the host computer 8.
Is output. Then, the CPU 10 communicates with the communication interface 1
The processing order data Da received via 3 is temporarily stored in the work file 12b of the RAM 12. Next, the CPU 10 reads the last record of the processing order data Da received in the previous week from the processing order file 12a, and determines whether or not this matches the first record of the data received this time. The duplication record is provided for the following reason. That is, the processing order data Da for one week output from the host computer 8 is originally obtained by dividing data for one month. Therefore, the last record and the first record are overlapped so that the continuity between the data received last time and the data received this time can be confirmed.

If the continuity of the data received this time is confirmed, the contents of the work file 12b are stored in the processing order file 1
Registered in 2a. As a result, the contents of the processing order file 12a are updated to the data received this time. Next, CPU10
Reads the processing order data Da from the processing order file 12a one record at a time, and performs the next data processing.

In this case, frame numbering for each vehicle category is performed based on the data of the fields F4 (model code), F8 (series: destination), F6 (number), and F9 (frame number to start stamping) of the read record. Then, the contents of the above-described check file 12c (see FIG. 6) are checked. That is, the frame number at which embossing is started is compared with the last frame number in the previous week for each vehicle division. If the frame number at which embossing is started is a number smaller than the last frame number, the vehicle division Is determined to have a double numbering, and an error is displayed. On the other hand, if the frame number at which embossing is started is the number next to the last frame number, it is determined as a serial number and numbering is performed. The numbering means that a new final frame number is obtained from the frame number (F9) at which embossing is started and the number of embossed frames (F6), and the new final frame number is obtained.
It is to register in the corresponding vehicle classification column of c. Thus, the last frame number of the check file 12c is updated and registered.

Check of record division This check is a data check of field F11 (record division) in the read record. This is to exclude the record from the numbering operation of the above-described item when, for example, a flag indicating “rework” or “shelf-storage” that suspends embossing is set in this field F11. The term "reworking" means that the member to be embossed is sent to the machining step again, and the term "shelf-up" means that embossing is reserved due to a change in the production plan or the like. On the other hand, if such a flag is not set, the item numbering operation is executed.

Creation of embossed master file In the above-described section, when the content of the check file 12c is updated, the content of the file 12c is read out and developed into a frame number in a continuous numerical order. For example, when the last frame number shown in FIG. 6 is registered, the frames are developed in the order of the frame number of each vehicle section as shown in FIG. Then, the field data (F1 to F8, F10, F11) corresponding to the frame number of each vehicle developed in this manner is edited, and the embossed master file is edited.
12d (see FIG. 7) is created.

(2) Stamping Operation The data control unit 6 reads out frame numbers sequentially from the beginning of the stamping master file 12 d and supplies the frame numbers to the machine controller 5. In the machine controller 5,
The supplied frame number is transferred to the operation panel 2. The operation panel 2 supplies the sent frame number to the embossing machine 1, whereby the numerical value of the embossing section of the embossing machine 1 is controlled. Next, the worker cuts the frame member into the stamping machine 1.
, And a predetermined button is operated, a frame number is stamped on the member. Then, the embossing machine 1 outputs a completion signal indicating the completion of the embossing to the operation panel 2, and the operation panel 2 supplies the completion signal to the data control unit 6. As a result, the data control unit 6 reads the next frame number and supplies it to the machine controller 5 again. In this manner, the frame numbers registered in the embossing master file 12d are subsequently embossed.

[Effects of the Invention] As described above, according to the present invention, the determination means d
Compares the first frame number and the last frame number for each vehicle segment, and determines that the first frame number is a double numbering if the first frame number is smaller than the last frame number. If it is a number next to the last frame number, it is determined to be a serial number. Then, the control means e displays an error when the judgment result indicates that the numbering is double, and when the judgment result indicates that the numbering is consecutive, a new final number obtained from the starting frame number and the number of stamps is obtained. Since the frame number is registered in the data table c, it is possible to automatically confirm the continuity of the frame number data and set a continuous frame number for each vehicle section.
