Abstract

PURPOSE:To automatically confirm the continuity of frame number data by examining if there is any datum, which coincides with the first datum of a newly received data group, among a previously received data group and, if there is one, deciding that there is the continuity between the two data groups. CONSTITUTION:A memorizing means 'b' memorizes frame data numbers, which were received by a communication control means 'a', while a retrieving means 'c' examines the data within the memorizing means 'b' to detect if there is any datum, which coincides with the first datum of a newly received data group, among a previously received data group. When no such a datum is detected, a deciding means 'd' decides that there is no continuity between the previously received data and the newly received data, and, when such a datum is detected, the deciding means 'd' decides that there is the continuity. When the first datum of the newly received data coincides with the last datum of the previously received data, the deciding means 'd' decides that the last end of the previously received data is immediately followed by the newly received data, and, the data of the previously received data, which are located on and after the datum coinciding with the first datum of the newly received data, are replaced with the newly received data.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a production control device suitable for use, for example, in controlling the stamping of frame numbers on an automobile production line.

``Prior Art'' On an automobile production line, a serial number is stamped on the frame in order to identify the vehicle being produced. This serial number is generally called a frame number, and is used not only to identify the vehicle on the production line, but also for various registrations and management after production.

The frame numbers must be stamped on the frames one after another according to the production plan, or care must be taken to avoid double stamping. That is, if the same number is stamped on two or more frames, the vehicle identification function will be lost, which will cause some management problems. Therefore, conventionally, the operator who stamps the stamps visually checks the stamps using a check list or the like.

``Problems to be Solved by the Invention'' By the way, frame numbers to be stamped are instructed from the main computer to each production line based on a production plan. Here, the indicated frame number data is excessive data. This is because production lines generally set production volumes on a weekly basis. On the other hand, since production planning is usually done on a monthly basis, one month's worth of frame number data is prepared in the main computer.

Therefore, the main computer divides the -month's worth of data into weekly units and instructs the divided data to the production line for each week.

In this case, if the frame number data instructed to the production line is correct, each frame number data should have continuity. However, due to operational errors or setting errors on the main computer side, the continuity of frame number data instructed to the production line may be impaired. In this way, if discontinuous frame number data is specified, double stamping or empty frame numbers will occur. Therefore, the continuity of frame number data must be thoroughly checked, but conventional manual checks have not been sufficient.

Furthermore, when there is a change in the production plan, it is necessary to change the frame number data, but this process requires time and errors when done manually.

The present invention has been made in view of the above-mentioned circumstances, and therefore provides a frame number system that can automatically check the continuity of frame number data instructed by a main computer, and can also easily change the frame number data. The purpose is to provide a management device.

"Means for Solving the Problem" The invention according to claim 1, as shown in FIG. 1, comprises a communication control means a that receives frame number data supplied from the outside, The storage means stores the data received by the storage means, and by searching the data in this storage means, it is detected whether or not the data group received last time contains the same data as the first data of the data group received this time. If the same data is not retrieved by the retrieval means C, it is determined that there is no continuity between the previously received data and the currently received data, and if the same data is retrieved, there is continuity. It is characterized by comprising a determining means d for determining.

Further, in the invention according to claim 2, when the first data of the currently received data and the last data of the previously received data match, the currently received data is located at the rear end of the previously received data. In the invention according to claim 3, wherein the determining means recognizes that the data are connected, when the first data of the currently received data matches other than the last data of the previously received data, The present invention is characterized in that data subsequent to the matched data in the previously received data is rewritten with the currently received data.

"Operation" Search means C searches to see if there is data in the data group received last time that matches the leading data of the data group received this time. And if there is matching data,
The determining means d determines that there is continuity of data. Therefore, an external device (such as a host computer) that supplies frame number data must position the data that matches the data in the previously supplied data group at the beginning of the currently supplied data to indicate data continuity. Bye.

"Embodiments" 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 an embodiment of the present invention. In the figure, l is a stamping machine that stamps a frame number, and when an operator sets a frame member and presses a predetermined button, the frame number is automatically stamped. Reference numeral 2 denotes an operation panel, which gives various commands and frame numbers to be stamped to the stamping machine 1. Further, the stamping machine 1 outputs a completion signal to the operation panel 2 when stamping for one machine is completed. 3 is a control panel, which supplies various data to the operation panel 2; This control panel 3 is composed of 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 are configured to exchange data with the host computer 8, respectively. The host computer 8 supplies one week's worth of machining order data to the data control unit 6 based on the production plan. The processing order data includes the processing order, loft number, model, type, color, frame number, etc. of the vehicle to be processed. Further, since production planning is usually done in units of one month, the data is divided into one week's worth and supplied to the data control unit 6. When the data control unit 6 is supplied with the machining order data, it checks its continuity, performs various processing, and then supplies frame number data to the machine controller 5. Note that data processing in the data control unit 6 will be described later.

The machine controller 5 outputs the frame number supplied from the data control unit 6 to the operation panel 2 along with a signal for controlling the stamping machine 1. Furthermore, the machine controller 5 rearranges the frame numbers based on the ratio setting data supplied from the host computer 8.

What is ratio setting data when performing heterogeneous mixed production? This is data showing the production ratio of the models in the factory. The reason why frame numbers are rearranged is to achieve the best efficiency, since when manufacturing by mixing different models at a predetermined ratio, production efficiency is determined by how each model is mixed. For example, when producing models A and B at a ratio of 3:2, it is efficient to produce them in a pattern of A→B-A-A-B. Here, since the frame number is a serial number for each model, it is necessary to rearrange it according to the above pattern.

Next, the configuration of the data control section 6 will be explained with reference to FIG. In the figure, lO is the CP that controls each part of the circuit.
U, 11 is a ROM in which programs etc. are stored, 12
is a RAM in which various data are temporarily stored. I3 is a communication interface, which controls data exchange with the host computer 8 and machine controller 5.

14 is an operation unit consisting of a keyboard, etc., and CPU10
Give various commands to the 15 is a display control unit that controls the display of the CRT I 6 under the control of the CPU10.

Next, the operation of this embodiment will be explained. In order to simplify the explanation, an example will be taken in which the same model is produced, and the explanation of the processing of the ratio setting data will be omitted.

(1) Receiving processing order data At the beginning, one week's worth of processing order data is output from the host computer 8, and is temporarily stored in the RAM 12 via the communication interface 13 shown in FIG. Next, the display control section 15 displays the display shown in FIG. 4 on the CRT display section 1.
Let 6 do it. In FIG. 4, 20 is a display window that displays the first record of the received data, and displays the first record of the processing order data transferred from the host computer 8. One record includes data specifying the loft number, date, model, color, production number, control number, and frame number. The frame number indicates the number of the first vehicle in the record, and the frame numbers of other vehicles are sequentially incremented by l in the stamping control.

Further, in the same figure, 21 is a display window that displays the corresponding record of the previous data. Here, the previous data is the processing ranking data of the previous week, and this data is
It is stored in the previous data area of MI2. The corresponding record refers to a record that matches the first record of the received data.

The matching search is performed by the CPU 10 reading the first record of the received data temporarily stored in the RAM 12 and searching the previous data area of the RAM 12 for data matching this. When a matching record (corresponding record) is searched, the message display field 22 will display a message (the first message) that says, "The attached part is at the end of the previous data. This is a normal weekly plan." , or [The glue section is in the middle of the previous data. When data is written, this data and subsequent data will be updated. This is a weekly plan change board. Please check the glue section. ” (second message) is displayed. In the former case, as shown in Figure 5 (a), the beginning of the received data matches the end of the previous data, and in the latter case, as shown in Figure 5 (b), the beginning of the received data matches the end of the previous data. This is a case where the beginning and the middle part of the previous data match. The reason why the matching part (the glued part) was provided in this way is as follows.

Since one week's worth of processing order data output from the host computer 8 is originally divided from one month's worth of data, there must be continuity between the previous data and the received data. Here, if one month's worth of data is simply divided and transferred, the continuity of the data cannot be confirmed even if the trailing end of the previous data and the starting end of the next data are compared. Therefore, we created sections (overlapping sections) for gluing, and confirmed continuity by checking their presence or absence.

When the eleventh second message is displayed, the CRT display device 16 displays a guide as shown in part 23 of FIG. When key Y on the operation unit 14 is pressed in accordance with this guidance, the CPU 10 takes in the received data as current data and combines it with the previous data. However, the method of merging differs depending on the message as follows.

First, if the first message is displayed, please refer to Figure 5 (
In the normal continuous mode as shown in b), the CPU
l0 connects the received data to the rear end of the previous data.

On the other hand, if the second messetune is displayed,
As shown in b), the received data continues from the middle of the previous data. In this case, the CPU 10 replaces the portion Ea of the previous data with the portions E and b of the received data, thereby combining both data. The case shown in Figure (B) is a case where there is a partial change in the production plan. In this process, continuity is checked and some data is changed at the same time. Furthermore, when all data is to be changed, a glue section is placed in the first record of the previous data, as shown in FIG.

When the first and second messages are displayed, when the key N on the operation unit 14 is pressed, the guide shown in section 24 of FIG. 4 is displayed on the CRT display device 16. In other words, “
Do you want to delete received data? (If you wish to receive new data, please delete it.)" is displayed. If key Y is pressed here, the received data temporarily stored in the RAM 12 will be erased.

On the other hand, if there is no pasting part in the previous data, that is, in the case shown in FIG. 5(d), there is no continuity of data. Since this is a setting error in the processing order data to be transferred, the following message is displayed in the section 22 shown in FIG. In other words, "The glue section cannot be found in the previous data. There is a data setting error.

Please contact the host computer. " is displayed. The worker communicates according to this message, searches for the cause of the error, and takes steps to receive the correct data again.

Further, when the host computer 8 sends out the first processing order data, the previous data does not exist, so in this case, the data becomes the initial setting data. Figure 5 (E)
indicates this state, and in part 22, the message "No previous data. This is the initial setting state." is displayed.

(2) Upon receiving the normal machining order and data, the stamping operation data control section 6 supplies the frame number to the machine controller 5. The machine controller 5 transfers the supplied one-frame pick-up to the operation panel 2. Operation panel 2 is sent to 1
A Niflame pick-up is supplied to the stamping manno 1, thereby controlling the numerical value of the stamping part of the stamping manno 1. Next, when the operator sets the frame on the stamping machine 1 and presses a predetermined button, the frame number is stamped. Then, the stamping machine I outputs a completion signal indicating completion of stamping to the operation panel 2, and the operation panel 2 supplies this completion signal to the data control section 6. As a result, the data control unit 6 changes the frame number to 1.
The frame number of the step is supplied to the machine controller 5. Then, a frame number is stamped in the same manner as above, and subsequent frame numbers that are successively incremented are stamped.

"Effect of the Invention J As explained above, according to the present invention, there is provided a communication control means for receiving frame number data supplied from the outside, a storage means for storing the data received by the communication control means, and a storage means for storing the data received by the communication control means. a search means for detecting whether or not the same data as the leading data of the data group received this time is present in the data group received for each song by searching the data in the means; and the search means searches for the same data. If the data is not retrieved, it is determined that there is no continuity between the previously received data and the currently received data, and if the same data is retrieved, it is determined that there is continuity. The continuity of the instructed frame number data can be automatically confirmed, thereby making it possible to reliably prevent double stamping.

Furthermore, as described in claim 3, if the data matches other than the first data of the currently received data or the last data of the received song data, the data after the matched data among the previously received data is determined by the currently received data. If you rewrite it, you can easily deal with frame number changes,
Improved adaptability to changes in production plans.
