Description

Method and program for collecting stored data of stored items

The present invention relates to a storage data collection method and a program for collecting stored items for collecting inventory data of dies and jigs.

金 Molds are increasing as product types increase. In addition, since service parts (repair parts) must be stored even after mass production is discontinued, it is also necessary to store a mold for molding the service parts over a long period of time. For example, service parts are 15 years for automobiles, 7 years for consumer goods, and 30 years for nuclear power. Accordingly, companies that produce parts using molds have a huge number of molds. Moreover, in companies that have production bases not only in Japan but also overseas, the molds that are held are scattered in each country, and the molds are frequently transferred between countries.

Conventionally, mold management typically creates a ledger on a computer and relies on humans for data input, but it is very time consuming with work such as actual verification. The present inventors give a QR code (registered trademark) to a mold, and further give a QR code (registered trademark) to a mold management shelf, a production facility, a tool management shelf, an operator, etc. The technique which manages data similarly is proposed (refer patent document 1).

Japanese Patent Laying-Open No. 2015-179348 (paragraph [0045])

Taking automobile-related production forms as an example, a parts manufacturer that delivers parts to a finished product manufacturer may outsource production to a secondary subcontractor. In this case, the mold owned by the parts manufacturer is lent to the secondary subcontractor. In such a form, the responsible entity that manages the mold and creates the ledger or the like is the component manufacturer. Typically, the purchasing department of a parts manufacturer manages these, but it has a huge number of dies, and the dies that are held are scattered in each country. In the present situation where the transfer is frequently performed, it is not possible to accurately inventory the mold. For this reason, there is a difference between the mold asset ledger and the actual storage, and there is a real difference between the asset and financial problems. In addition, the current situation is that the person in charge of the parts manufacturer cannot go to the secondary subcontractors in Japan or overseas factories, and the only way to do this is to trust the storage company's report with the management based on the good faith theory.

In addition, overseas societal instability, bankruptcy of business partners, and out of business suddenly transferred production to other contractors, returned to Japan, and so-called production transfer began to occur frequently. Another factor is the need to change production areas in response to exchange rate fluctuations.

In view of the circumstances as described above, an object of the present invention is to provide a storage data collection method and program for collecting inventory data of dies and jigs quickly and accurately without labor. It is to provide.

In order to achieve the above object, a method for collecting stored data of a stored item according to an aspect of the present invention includes a QR code (registered trademark) including first information for identifying a worker who confirms the stored item. ), A first name plate provided with a QR code (registered trademark) including second information for specifying the stored item is attached to a predetermined position of the stored item, and the storage is performed. A second nameplate provided with a QR code (registered trademark) including third information for specifying a place where an object is stored is attached to a predetermined position, and the operator takes a photographing function and a QR code (registered trademark). Using a communication terminal having a recognition function, the QR code (registered trademark) displayed on the display member is photographed, the first information is obtained from the photographed result, and the QR engraved on the first nameplate is obtained. Code (registered trademark) The second information is obtained from the photographing result, the QR code (registered trademark) engraved on the second nameplate is photographed, the third information is obtained from the photographing result, and the stored item and the storage The storage state of the object is photographed, and the communication terminal transmits the first information, the second information, the third information, and the photographing data of the photographed stored material and the storage state of the stored material to the database.

<Name plate engraved with QR code (registered trademark)>
A typical example of a nameplate engraved with a QR code (registered trademark) in the above embodiment will be described.

FIG. 10 is a top view showing a configuration of a mold identification plate as a name plate engraved with a QR code (registered trademark). FIG. 11 is a partial longitudinal sectional view thereof.

As shown in FIGS. 10 and 11, the mold identification plate 201 is a mold identification plate (name plate engraved with a QR code (registered trademark)) attached to the mold 40. Here, the mold includes not only the mold itself but also mold parts constituting the mold. In some cases, each mold part is managed with a mold identification plate 201 attached thereto. The mold 40 includes various types such as a press mold, a forging mold, a casting mold, and an injection mold.

The mold identification plate 201 includes a mold identification plate main body 210, an alumite layer 220, and an inorganic / organic composite coating layer 230.

The mold identification plate body 210 is made of aluminum, for example, a rectangular plate-shaped member. The plate thickness of the mold identification plate body 210 is, for example, 1 to 1.5 mm, and may be other metals such as stainless steel in addition to aluminum.

The mold identification plate main body 210 has a display area 211 at substantially the center thereof.

The display area 211 includes a first display area 212 provided with a recess 214 corresponding to a QR code (registered trademark) as a two-dimensional code corresponding to information on the mold 40, and a company name, a serial number, etc. directly by visual inspection. And a second display area 213 provided with a recess 214 corresponding to information that can be confirmed. These recesses 214 are provided by, for example, cutting.

The information about the mold 40 is as described in the above embodiment, but as another example, a server (not shown) that stores production technology information, production / facility information, and management information is accessed. This is information for accessing the production technology information, production / facility information, and management information of the individual mold among the mold information stored in the server. The information stored in the server may be stored in one server, or may be distributed and stored in a plurality of servers. The information on the mold may include, for example, information on the second display area 213 and other information in addition to the information for access described above.

Here, the production technology information includes, for example, a mold manufacturer, mold data, the number of production shots, mold maintenance information, and location. The production / equipment information includes, for example, production condition data such as molding conditions, production machine / tool specification, production line data, maintenance information such as equipment, quality information, and production environment information such as power supply / temperature / humidity. The management information includes, for example, a QC process chart, a work manual, and an inspection standard document.

The depth of the recess 214 is preferably in the range of 0.1 mm to 0.2 mm, and more preferably 0.15 mm. If it is shallower than 0.1 mm, the inner side surface of the concave portion 214 may not be recognized as the concave portion 214 when it becomes a slope during processing, for example. It becomes easy and may not be recognized as the recess 214. If the depth of the concave portion 214 is around 0.15 mm, these are prevented and the QR code (registered trademark) is correctly recognized.

The alumite layer 220 is provided on the surface of the mold identification plate main body 210 including the surface of the display area 211 so as to avoid the recess 214. The alumite layer 220 is provided by an alumite process described later. When the surface of the mold identification plate main body 210 is viewed from the upper surface, the region where the alumite layer 220 is provided is black, and the concave portion 214 is the color of the gloss of aluminum itself. In addition to the alumite layer, the present invention includes any layer that makes the color difference between the surface and the recess clear. However, when the mold identification plate main body 210 is made of aluminum, the anodized layer 220 is preferable. This is because the alumite layer 220 can be easily formed by an alumite treatment, and the color difference from the concave portion becomes black.

The inorganic / organic composite coating layer 230 is made of a transparent and heat-resistant two-component room temperature curable inorganic / organic hybrid coating (for example, “FOC700 (trade name)” manufactured by FECT). The heat resistance is preferably in the range of 70 ° to 200 °. Thus, even when the mold is used or stored in a severe thermal environment, the inorganic / organic composite coating layer 230 is not destroyed, and the QR code (2D code) is used for a long time. The recognition rate of (registered trademark) does not decrease.

The inorganic / organic composite coating layer 230 is provided with a concave portion 214 corresponding to a QR code (registered trademark) as a two-dimensional code corresponding to information on the mold on the surface of the mold identification plate main body 210. Cover and fill the recess 214. The surface of the inorganic / organic composite coating layer 230 is substantially flat including the position corresponding to the recess 214. In addition, the inorganic / organic composite coating layer 230 preferably has a thickness of 0.1 mm to 0.2 mm as a height from the surface of the mold identification plate body 210. When the thickness is smaller than 0.1 mm, the display area 211 is not sufficiently protected by the inorganic / organic composite coating layer 230. For example, there is a possibility that the inorganic / organic composite coating layer 230 is broken and the display region 211 is exposed on the surface, or that the concave portion 214 of the display region 211 is mechanically adversely affected via the inorganic / organic composite coating layer 230. On the other hand, the thickness is up to 0.2 mm, and the above protection is sufficient. If the thickness is larger than 0.2 mm, the coating material is wasted.

The inorganic / organic composite coating layer 230 does not need to cover the entire area of the surface of the mold identification plate main body 210 as shown in FIG. That is, the inorganic / organic composite coating layer 230 only needs to cover at least the surface of the display region 211, and a step of applying an inorganic / organic composite coating to be described later by covering a certain area including the surface of the display region 211. This eliminates the need for strict accuracy and saves coating materials.

In the mold identification plate 201, information about the mold 40 is displayed by providing a recess 214 corresponding to a QR code (registered trademark) as a two-dimensional code in the display area 211, and the surface of the display area 211 is inorganic. Since the organic composite paint layer 230 is provided, a QR code (registered trademark) as a two-dimensional code for each individual can be attached in a simple process and can be produced in a short time.

In addition, the transparent and heat-resistant inorganic / organic composite coating layer 230 is provided with a recess 214 corresponding to the two-dimensional code so as to cover the surface of the display area 211 and fill the recess 214. Oil does not accumulate, and the recognition rate of the QR code (registered trademark) as a two-dimensional code does not decrease over a long period of time. In addition, since the inorganic / organic composite coating layer 230 fills the recess 214, the adhesion between the inorganic / organic composite coating layer 230 and the display region 211 is increased, and durability can be maintained for a long time. For example, if the adhesion between the inorganic / organic composite coating layer 230 and the display region 211 is poor, gas or the like may accumulate in the concave portion 214 at the time of creation. There is a possibility that the recognition rate of the QR code (registered trademark) as a two-dimensional code is lowered. Further, if the non-attachability is poor, the inorganic / organic composite coating layer 230 may be peeled off from the display area 211 and the display area 211 may be exposed.

This mold identification plate 201 is typically manufactured by the following method.

FIG. 13 is a flowchart showing a configuration of a method for manufacturing the mold identification plate 201.

First, a mold identification plate main body 210 having a plate thickness of, for example, 1 to 1.5 mm and made of rectangular and plate-shaped aluminum is prepared (step 401).

Next, an alumite treatment is performed on the entire surface of one side of the mold identification plate body 210 (step 402) to form an alumite layer 220.

Next, a recess 214 is formed by cutting to a depth of about 0.1 mm to 0.2 mm in the center of the anodized surface (surface) of the mold identification plate body 210 (step 403). The display area 211 is formed.

As described above, the display area 211 includes a first display area 212 provided with a recess 214 corresponding to a QR code (registered trademark) as a two-dimensional code corresponding to information on a mold, a company name, and a serial number. There is a second display region 213 provided with a recess 214 corresponding to information that can be directly confirmed visually.

Next, as shown in FIG. 12, an inorganic / organic composite paint is applied to the surface of the mold identification plate main body 210 so as to cover a certain area including the surface of the display area 211 (step 404). An inorganic-organic composite coating layer 230 having a thickness of about 1 mm to 0.2 mm is formed.

As described above, the layer 230 that protects the concave portion 214 is provided, and the layer 230 is an inorganic-organic composite coating layer that is formed of an inorganic organic composite coating, so that the layer that protects the concave portion 214 is formed by a simple coating process. In addition, the heat resistance, durability and the like are very excellent, and the recognition rate of the two-dimensional code can be maintained for a long time. In addition, bubbles and the like in the recess 214 do not float on the surface and remain in the recess 214 at the time of application, and the adhesion is extremely high.

Moreover, as compared with the formation of a protective layer that requires firing or the like, in this technique, the protective layer 230 can be formed by a simple coating process, and thus the protective layer 230 has extremely high adhesion in a simple and short process. Can be formed. Furthermore, by using a two-component room temperature curing type inorganic organic hybrid paint (for example, “FOC700 (trade name)” manufactured by FECT), transparency can be maintained over a long period of time, so that the recognition rate of a two-dimensional code is maintained over a long period of time. can do.

Fig. 14 shows data disclosed by FECT regarding transparency. In the figure, FOC700 color white as a paint, Bonde steel plate (150 x 50 x 0.3 mm) as a material, film thickness as a film thickness: 25 to 30 μm, curing conditions as drying at 80 ° C for 30 minutes, room temperature for 2 weeks It was served after being left.

In addition, the material for the above-mentioned inorganic / organic composite coating layer is not limited to the illustrated material, and any material having the same function can be used in the same manner.

Further, the cutting of the recess in the display area is not limited to the above embodiment, and other cutting may be used.
