DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of data management in the manufacture of molded articles, and more specifically, manages dimensional data from the design of a molded article to an actual product, and improves the efficiency of investigating the causes of errors. The present invention relates to a data management system capable of achieving the following.

[0002]

2. Description of the Related Art In magnetic tape cassettes, flexible disks, MDs, MOs, and various types of recording media, molded products such as cartridges (cassette half), shells, and storage cases for storing the media themselves are injection molded. Many are used.

[0003] In various products using such molded products, in order to stably produce an appropriate product, it is important that a design and an actually manufactured product match properly. It is. Therefore, for example, when a difference (error) between a design (designed product) and a manufactured product exceeds a permissible range in a trial production of a product, the factors are separated and the cause is determined. So we need to deal with it.

As is well known, when a new molded product is designed, a mold is designed on the basis of the design drawing in consideration of the shrinkage ratio of the resin material to be the molded product, and the like. Then, a mold is manufactured, and a product is manufactured using the manufactured mold.

In the manufacture of such a molded product, in order to separate the causes of the error between the design and the manufactured product and to investigate the cause, usually, the dimensions of the designed product (product design dimensions), the design die Four dimensions are used: dimensions (design dimensions of the mold), dimensions of the fabricated mold (actual dimensions of the mold), and dimensions of the fabricated product (actual dimensions of the product). By analyzing these, it is possible to find out whether the cause of the error between the design and the product is, for example, whether it is in the design of the mold, in the manufactured mold, or in the design itself. Will be considered.

However, in the conventional production of molded products, the product design dimensions and the actual product dimensions are managed by the product designer (the manufacturer of the molded product), and the mold design dimensions and the actual mold dimensions are not controlled. Currently, it is managed by the mold designer (the mold supplier side). Moreover, there is no means for systematically managing data. Therefore, when performing the factor separation and investigation of the error between the design and the manufactured product, information is provided from the other side, and this is analyzed, for example, by comparing it on paper. However, the current situation is very inefficient. Moreover, proper analysis is difficult, which leads to waste of resources.

An external storage device such as a server connected to the management system 10 may be used, or a removable data storage such as Zip, CD-R, or magnetic tape cassette may be used. Is also good.

Hereinafter, the present invention will be described in more detail by describing the operation of the management system 10 with reference to a schematic diagram of an example of a display screen on the display 12 shown in FIG.

In the management system 10 of the present invention, a molded product (for example, an upper cartridge of a magnetic tape cassette, etc.)
When managing the design drawing of the product, the product design dimension, the mold design dimension, the mold actual dimension, and the product actual dimension, first, the design drawing of the corresponding molded product is input and stored in the database 20.

There is no particular limitation on the method of inputting the design drawing.
What is necessary is just to carry out similarly to capture of various images (image files) in PC etc. For example, the management system 1 of the present invention
0 in the same manner as the operation of various software, the menu bar 30 on the display screen shown in FIG.
(The pull-down menu or the toolbar may be used) to input a design drawing, and
Specify the design drawing to be input. In response, the input processing means 16 reads the design drawing (the file or folder) from the supply source and stores the design drawing at a predetermined position in the database 20. In FIG. 2, the upper part of the menu bar 30 is
This is the so-called title bar.

The design drawing may be read from a recording medium such as an HD or a CD-R, and may be read from the Internet or a LAN (Local
Area network) or other communication network. Further, the design drawing itself may be read by a scanner. Alternatively, in the management system 10 (computer constituting the management system 10), a design drawing may be created by various kinds of image creation software, and the input processing means 16 may store the design drawing in the database 20.

In the management system 10 of the present invention, there is no particular limitation on the image format (graphics format) that can be used, and it may be a two-dimensional image format or a three-dimensional image format. It may be available or it may be in the original image format. Specifically, IGE
3D CAD / CAM format such as S and STEP,
Examples include a vector graphics format such as DXF / DWG and HPGL, and a raster graphics format such as TIFF and JPEG.

Further, a product design dimension, a mold design dimension, a mold actual dimension, and a product actual dimension corresponding to the inputted design drawing are inputted. For example, start the management system 10 and
First, the user moves the pointer 32 using the mouse 14a or the keyboard 14b, presses the input button 34 (for example, clicks), and instructs input of a dimension. Next, in the same manner as above, a design drawing for inputting dimensions is selected using the menu bar 30. It goes without saying that the input of the dimension may be performed subsequently to the input of the design drawing. In response, the input processing means 16 reads the designated design drawing (in FIG. 2, shown as a cube for simplicity of the drawing) from the database 20, and
As shown by 6, the display is displayed on the display 12.

Next, by operating the mouse 14a and the like, FIG.
The pointer 32 (the pointer 32 indicated by the solid line) is moved to the position where the dimension is input in the design drawing 36 as shown in FIG. In response, the input processing means 16
Displays an input window 38 for inputting dimensions on the display 12. In the illustrated example, the input window 38 is formed of a four-step frame, and includes, from the top, a product design dimension input field, a mold design dimension input field, a mold actual dimension input field, and a product actual dimension input field. is there.

Further, the user moves the pointer 32 to a column corresponding to the dimension to be input and clicks on it to input the dimension. For example, when inputting the product design dimensions, the pointer 32 is moved to the uppermost product design dimension input field and clicked, and the die design dimensions are input using the keyboard 14b. Hereinafter, similarly, the mold design dimensions, the actual mold dimensions, and the actual product dimensions are input.

After all dimensions have been entered, the registration button 40 is pressed by the pointer 32. In response to this, the input processing means 16 associates the position indicated on the design drawing 36 with each input dimension (dimension data), and stores it in the database 20. That is, the position designated on the design drawing 36 and the input dimension are linked and recorded at a predetermined position in the database 20. The input and management of such dimensions may use various table creation / management software.

The method of inputting these dimensions is not limited to the above, and various methods can be used. For example,
A button for inputting / registering each individual dimension, such as a product design dimension registration button and a die design dimension registration button, may be set, and each dimension may be input.

After the dimensions of one position are input in this way, similarly, the next position for inputting the dimensions is designated by the pointer 32, and each dimension is input / registered. When the above operations are sequentially performed and the input of the dimensions at all the positions to be input is completed, the operation of the dimension input is ended using, for example, the menu bar 30.

In the management system 10 of the present invention, the input of dimensions is not limited to the simultaneous input of all four dimensions. For example, first, only the product design dimensions are input, and otherwise, the input design drawing is input. Every time we get the dimensions corresponding to
Of course, the input may be performed by the above operation. Alternatively, the design drawing data may include the product design dimensions, and the product design dimensions may be input simultaneously with the input of the design drawings.

In such a management system 10 of the present invention, when the input design drawing and its dimensions are viewed, the management system 10 is started up, the pointer 32 is operated, and the reading button 42 is pressed to read out. Instruct. Next, similarly, a design drawing for inputting dimensions is selected using the menu bar 30. In response, the output processing means 1
8 is read from the database 20 and the display 12 is displayed.

At the time of displaying the design drawing 36, a position where the difference (error) between the product design dimension and the actual product dimension exceeds a predetermined value (all positions, or only a position where a dimension display described later is instructed may be used). ) Is preferably clearly indicated by means such as making the luminance higher than other positions or changing the color from other positions. Further, in a dimension display instruction to be described later, when an instruction to display a dimension at a position where an error is equal to or more than a predetermined value is given, a sound may be used to notify the user.

Next, by operating the mouse 14a and the like, FIG.
The pointer 32 (pointer 32 shown by a dotted line) is moved to the position where the dimension is to be displayed in the design drawing 36 as shown in FIG. In response, the output processing means 1
8 reads the corresponding dimensions from the database 20,
As indicated by reference numeral 44 in FIG.
To be displayed. In the illustrated example, as an example, from above,
The product design dimensions, mold design dimensions, mold actual dimensions, and actual product dimensions are displayed. If you want to see the dimensions at another location,
Move the pointer 32 and click on the desired position.
When the operation is completed, the operation of displaying the dimensions is similarly ended using the menu bar 30.

As is apparent from the above description, according to the management system 10 of the present invention, the design drawings conventionally managed separately, and the product design dimensions, mold design dimensions, Product information such as the actual dimensions of the mold and the actual dimensions of the product can be associated and managed collectively by an easy operation. Therefore, according to the present invention, in designing and manufacturing a molded product such as a cartridge of a magnetic tape cassette, the work efficiency in the case where there is a large error between the design and the molded product, and the design efficiency of a new molded product, etc. Can be greatly improved.

In the management system of the present invention, the dimensions are displayed by using the menu bar 30, for example, without using the read button 42, by displaying a design drawing from which data is read, and clicking a position at which the user wants to know the dimensions. The corresponding dimensions may be displayed simply by moving the pointer 32 (or simply by moving the pointer 32). Further, it is needless to say that the display of the dimensions at each position may be performed in a state where all four dimensions have not been input.

It is preferable that the management system 10 of the present invention has a function of automatically calculating the die design dimensions from the input product design dimensions in addition to the management of the design drawings and the respective dimensions. More preferably, the database 20
Analyzes various design drawings and various dimensional data recorded in, and corrects the calculation method and calculation results,
Calculate the most appropriate mold design dimensions. There is no particular limitation on the method of calculating the mold design dimensions from the product design dimensions, and a known method of calculating by multiplying the shrinkage ratio of the resin as the raw material may be used. In addition, as the calculation method, a known method performed by a computer may be used.

Further, in the management system 10 of the present invention, various design drawings and various dimensional data recorded in the database 20 are analyzed to calculate a shrinkage ratio, and in addition to displaying the dimensions, Preferably, the shrinkage is also displayed.
