Description

Method of manufacturing a mold for molding a product sample, method of manufacturing a product sample, and a product sample

The present invention relates to a method of manufacturing a mold for molding a product sample, a method of manufacturing a product sample, and a product sample, which facilitate manufacture of a sample by utilizing the actual product.

2. Description of the Related Art Conventionally, for example, in the case of in-store sales of retail stores such as department stores, supermarkets, and convenience stores, in order to convey the attractiveness of products to consumers, real products may be displayed as product samples on displays and showcases. However, since the actual product degrades with the display period (for example, drying, rot, discoloration, etc.), the retail store frequently changes the product sample according to the property of the product. I had to do it. Therefore, attention has been focused on the use of product samples imitating actual products that are less likely to deteriorate even if the display period is prolonged.

As a product sample, what imitated the appearance of goods with wax and predetermined synthetic resin is known. Since there are many types of wax and synthetic resin product samples and their shapes are complicated, they are manufactured one by one by skilled technicians. For this reason, the production time is long, and not only the rent for that portion is increased, but also the quality of the product sample has been varied from handmade. Therefore, the product samples have had the problems of shortening the manufacturing time and making the quality uniform.

Then, the manufacturing method of the food sample which coat | covers with a transparent resin material is proposed, for example, after vacuum-drying the real thing of a foodstuff, without using a wax or a synthetic resin (for example, refer patent document 1). That is, while the deterioration due to various chemical reactions is suppressed by bringing the food into a dry state, the transparent resin material blocks the moisture that the outside air gives to the food. As a result, a food sample suitable for long-term display can be manufactured in a short time and at a low cost.

Japanese Patent Application Laid-Open No. 56-45181

However, in the food sample by the manufacturing method of the patent document mentioned above, since only one sample can be manufactured with respect to one real thing, it is a manufacturing method unsuitable for mass production. That is, since it is necessary to apply vacuum drying and a coating of a transparent resin material to each real food, the production time per sample is never short. Furthermore, due to the quality of the actual product, the vacuum drying and the quality of the coating of the transparent resin material, the quality of each sample tends to vary. That is, even with the same manufacturer and the same kind of food, experience of skilled technicians or the like so that each food sample maintains a certain quality because the ingredients (eg, water content, hardness, etc.), shape and color of the real thing are different. I can not but rely on my intuition. In addition, the actual value of food as a sample may decline over time because the actual food may be deformed or rotted in the transparent resin material.

The application of the product sample is diverse, for example, not only at the store description but also at the exhibition of the product and the display in the display space permanently installed in the company. For example, at a product exhibition, product samples may be required suddenly and in large quantities, so there is a method for manufacturing product samples that can be mass-produced in a short period of time, and deterioration such as shape deformation for complicated transport and display. There is a need for commodity samples that are unlikely to occur.

In addition, some of the products may be combined into a single product by combining a plurality of individual products, or may be combined into a single product in a predetermined packaging container (for example, assortment of food, lunch box, etc.) . In this case, since a plurality of product samples are required for one product, it takes time to manufacture individual product samples, and if the product quality is different by manufacturing them individually The overall balance may be lost and the quality of the product sample may be significantly reduced. In addition, the manufacturing method of the patent document mentioned above is an idea of processing as a sample of each food item, and different methods of vacuum drying and coating of a transparent resin material are different for each item, so a plurality of components of the item differ. It is not suitable to collect and sample products at once.

Generally, for mass production of objects, molding technology using a mold is utilized. In the molding technology, a metal or a synthetic resin is molded into a desired object with a mold designed according to the shape of the object. Then, a predetermined design tool, such as three-dimensional CAD, is used to manufacture a mold. However, it is more difficult to design an object having a complicated shape, and the manufacturing cost tends to be expensive. Therefore, judging comprehensively, including the amount of production and the cost of production, the need for producing a product sample in a mold was low.

On the other hand, predetermined image analysis tools for easily grasping the shape of an object are also in widespread use. Then, based on the result of image analysis of the shape, it has become possible to design the shape of the object with a predetermined design tool. That is, if the shape of a product is grasped by a predetermined image analysis tool and the shape of a product sample is designed by a predetermined design tool, not only the manufacturing cost of the mold can be suppressed but also desired mass production becomes possible. Therefore, it should be applicable to the manufacture of commodity samples.

However, unevenness of the surface of the product, grooves and the like may affect the image analysis. That is, in order to grasp the shape of the product, it is also necessary to reduce the factor that causes the obstacle in the image analysis. Therefore, the inventors arrived at the idea of obtaining good image analysis results by reducing the unevenness of the surface of the product and closing the grooves and gaps as a creative idea. According to this idea, sample production and mass production of various products can be performed in a short time.

An object of the present invention is to provide a method for producing a mold for producing a product sample, a method for producing a product sample, and a product sample, which shortens the production time and realizes mass production with desired quality.

That is, the method for manufacturing a product sample molding die according to the present invention comprises the steps of vacuum packaging a product, the step of performing image analysis of the surface in the vacuum packaged state, and processing the result of the image analysis And manufacturing a mold for molding the sample.

Further, the step of freezing the product may be performed before the step of vacuum packaging the product.

Furthermore, in the method for producing a product sample according to the present invention, a substrate on which an image of the product is printed is molded using the mold for molding a product sample produced by the above-mentioned production method to produce a sample of the product A process may be included.

In addition, the product may be a food provided in a packaging container.

Further, the ultimate pressure of vacuum at the time of the vacuum packaging may be 0.05 to 0.2 MPa.

In addition, the base material may be a laminate sheet in which a printed film for lamination is attached to a sheet.

Further, the product sample according to the present invention may be manufactured by the above-described method for manufacturing a product sample.

"Goods" means an object with irregularities or grooves or gaps on the surface, an object that is prone to shadows anywhere on the surface, an object that is entirely moist on the surface, an object that is easily perishable, a predetermined vacuum package Any soft substance (including liquid) that can not withstand compression of any type may be used, and for example, food (such as rice, noodles, sugar beet, salad, fruits, etc.), plants, insects, or organs may be used. It may be served). In addition, the “product sample” corresponds to a part or all of a shape or state of a product (for example, a state in which the product is stored in a predetermined packaging container, a state in which the product is moving, etc.) For example, a three-dimensional molded article including a surface portion of a food stored in a predetermined packaging container, a surface of the packaging container and the whole surface of the food or the whole, a container main body and a lid of the packaging container with goods as motifs The molded product may be in the shape of a puzzle. In addition, a “commodity sample” may be a three-dimensional molded product including a container body or a lid, or a puzzle obtained by dividing the three-dimensional molded product.

The "vacuum packaging" may mean that the inside of a predetermined packaging film in which the above-mentioned goods are stored is vacuumed by a predetermined device. The vacuum ultimate pressure at the time of vacuum may be 0.05 to 0.2 MPa, preferably 0.08 to 0.15 MPa. If the vacuum ultimate pressure at the time of vacuum is less than 0.05 MPa, the packaging film does not adhere to the product, so that not only the shape of the product can not be identified but also shadow etc. easily occur. Not only does the packaging film adhere too tightly to break the shape of the product, it may also cause wrinkles on the surface. "Vacuum-packed state" means a state in which the unevenness of the product is alleviated by the compression in the film for packaging, and the grooves and gaps on the surface of the product are blocked by the film for packaging. May be The "surface in a vacuum-packed state" may mean the surface of the packaging film in which a predetermined shadow or water drop is not generated.

"Image analysis" may mean capturing the shape of the vacuum-packed surface as 3D data. For example, irregularities on the surface in a vacuum-packed state by laser irradiation with a 3D scanner are acquired as three-dimensional coordinate data (X, Y, Z), and the acquired coordinate data is used as a point group to obtain predetermined 3D data (for example, , Polygons, wireframes, surfaces, or solids). That is, the “image analysis result” may mean predetermined 3D data into which three-dimensional coordinate data has been converted.

“Processing the result of image analysis” may mean converting the above-described 3D data into STL (Stereolithography) data or editing into desired STL data. Also, it may include converting or designing acquired STL data so that it can be used in CAD (Computer-Aided Design) or CAM (Computer Aided Manufacturing). In addition, the above-described STL data may be used to cut or grind a predetermined material into the shape of a mold for molding a product sample.

As the “mold for molding a sample of goods”, the material may be metal or resin, and the method is die (eg, press, forging, casting) or mold (eg, injection mold, blow) A mold, a compression mold, a vacuum mold, a rotational mold, an extrusion mold, a metal powder injection mold, and the like) may be used, without limitation.

"Freezing the product" means that the entire product is solidified in a predetermined freezer set at about 0 ° C. or less, and the temperature in the freezer and the condition stored in the packaging container or not There is no limitation on heels. That is, it may mean that the shape is not deformed by the ultimate pressure of vacuum at the time of vacuum packaging, and the product is changed to a state in which the surface is not moist. In addition, before "the process of vacuum packaging the product", the shape of the product is not easily deformed by thawing, and it may be any state as long as water droplets are not generated on the surface, preferably a predetermined value. It may be immediately after taking out the product from the freezer.

The “image of the product” corresponds to a product obtained by photographing the product from a predetermined direction (for example, a direction in which the product is viewed in plan) prior to the “process for freezing the product” or the “process for vacuum packaging the product”. The image data may be subjected to predetermined processing (for example, trimming, color tone change, composition) on the image data, and may be monochrome or color. In addition, the medium (film) on which the “image of goods” is printed may be a single layer film formed of a predetermined material (for example, polyolefin type, polystyrene type, polyester type), and may be laminated by a known dry lamination method Or a film laminated by the known coextrusion method or a film laminated by the dry lamination method and a film laminated by the coextrusion method on a film laminated by the dry lamination method (hereinafter also referred to as "film for lamination") There may be included, and there is no limitation on the position (hierarchy) of the material forming the film or the layer on which the "image of product" is printed.

"Substrate" means a foam or non-foam thermoplastic resin sheet, for example, polystyrene foam sheet or polyolefin foam sheet or polyolefin (for example, polypropylene, polypropylene filled with inorganic filler) non-foam It may be a sheet or polystyrene (for example, high impact polystyrene containing an elastomer) non-foam sheet, and there is no limitation on the material forming the sheet. In addition, “a substrate on which an image of a product is printed” refers to a sheet on which an image is directly printed on the substrate or a laminate obtained by laminating the above-described film on the substrate (hereinafter, also referred to as a “laminate sheet”). ) May be.

In the method of manufacturing a mold for molding a product sample according to the present invention, a predetermined film adheres to the surface of the product in the step of vacuum-packing the product, thereby reducing the unevenness of the surface of the product, or reducing grooves or gaps on the product. As well as preventing the occurrence of shadows due to ups and downs or grooves or gaps, it is also possible to coat moisture on the surface of the product or to prevent corruption of the product. This makes it possible to reduce factors that impede the image analysis of the complex surface shape of the product. That is, since it is easy to apply a predetermined paint (for example, a paint for laser reflection of a 3D scanner) in the process of analyzing the surface of the vacuum packaged state, it is possible to obtain good image analysis results. Therefore, since it is possible to manufacture a mold for molding a product sample that accurately simulates the shape of a product, it is possible not only to significantly reduce the production time of the product sample as compared with the conventional method for manufacturing product samples by skilled workers. Mass production of highly reproducible product samples can be expected. Furthermore, such a product sample may be a three-dimensional molded product including a container body for packaging a product and a lid, and the effect of finding a new application as a product sample can also be expected.

In addition, by performing the step of freezing the product before the step of vacuum-packing the product, it is possible not only to harden liquid soft goods (for example, demi-glas sauce such as hamburger), but also to reduce the pressure by vacuuming at the time of vacuum packaging. Boiling can be prevented in advance. Therefore, an increase in the types of products to be sampled can be expected.

In addition, since the product is a food provided in a packaging container, a product sample of semi-liquid food (for example, curry, stew, mapo tofu, omelet rice) can be easily manufactured. Therefore, it can be expected to sample various kinds of food in a packaged state depending on the shape and packaging method of the packaging container.

In addition, since the ultimate pressure of the vacuum at the time of vacuum packaging is 0.05 to 0.2 MPa, not only is the shadow of the product which is an obstacle to image analysis hard to occur, but the product is soft without causing wrinkles in the packaging film. The product can be vacuum packaged in a desired state because the shape of the product is not broken. Therefore, by adjusting the vacuum ultimate pressure, it is possible to expect faithful sampling of various foods.

In addition, by using a laminate sheet in which a printed film for lamination is attached to a sheet as a substrate, it is possible to save time and labor for describing the shape and color of a product sample after production, and to significantly reduce the production time of the product sample. I can expect further.

Hereinafter, an outline of a method of manufacturing a product sample molding die according to the present embodiment and a method of manufacturing a product sample according to the present embodiment will be described with reference to FIGS.

As shown in FIG. 1, the method of manufacturing a mold for molding a product sample according to this embodiment includes a step S120 of vacuum-packing a product, a step S130 of image-analyzing the surface of the vacuum-packaged state, and the image analysis. The method may be characterized by including step S140 of manufacturing a mold for processing the result and molding a sample of the product.

Further, for example, when the product is soft, the step S110 of freezing the product may be performed before the step S120 of vacuum packaging the product.

In the method for producing a product sample according to the present embodiment, a film on which an image of the product is printed in step S210 and step S220 using the product sample molding die produced by the above-described production method Step (hereinafter, also referred to as "printing step on a substrate") S310, and steps S120 (or S110) to S140. The method may be characterized by including a step S320 of forming a sample of the product by forming a substrate on which the image of the product is printed using the mold manufactured in 4.

Further, the product used in the step S110 of freezing the product or the step S120 of vacuum packaging the product may be a food provided on a predetermined packaging container.

In addition, the vacuum ultimate pressure at the time of vacuum packaging in step S120 of vacuum-packaging a product may be 0.05 to 0.2 MPa.

Next, with reference to FIG. 1 to FIG. 3, details of the method of manufacturing a product sample molding die according to the present embodiment and the method of manufacturing a product sample will be described.
In the following description, liquid or semi-liquid soft food (for example, demi-glas sauce such as curry rice, omelet rice, hamburg, etc.) provided in a predetermined packaging container sold at a retail store is used as a product for forming a sample. You may employ | adopt and you may pass through process S110 which freezes goods.

In step S110 of freezing the product, the predetermined product is placed in a predetermined freezer set at about 0 to -20 ° C (for example, "MEDICAL FREEZER" manufactured by Sanyo Electric Co., Ltd.) for about 24 hours (or until the food freezes) You may put in it. After completion of freezing, the appearance such as the shape of the product may be confirmed.
In addition, in food, it may be in a state of being put in a container for packaging, but in consideration of appearance deformation (for example, reduction in volume) or positional deviation due to freezing or vacuum packaging, for example, food for sale It may be manufactured by different materials and cooking methods, or may be performed by raising the bottom and width of the ingredients with respect to the packaging container.

In step S120 of vacuum-packing the product, the product frozen in step S110 of freezing the product is taken out of the freezer and at least a predetermined vacuum packaging machine (for example, "HI-750" manufactured by HIPACK Co., etc. before the product is thawed) ), And covered with a predetermined film (for example, "SV film" manufactured by Omori Kasei Co., Ltd.), and vacuum processing may be performed with the vacuum ultimate pressure set at 0.05 to 0.2 MPa.
In addition, in view of the type of food and the state of vacuum packaging, the vacuum ultimate pressure at the time of vacuum may be appropriately changed to be in a suitable state. After vacuum processing, it may be possible to check the presence of grooves, gaps, depressions, shadows and wrinkles in the film that are difficult to be irradiated by the laser of the 3D scanner on the surface of the food covered with film. It may be opened and the same process may be performed again.

In step S130 of analyzing the surface of the vacuum-packed image, a white paint is applied to the surface of the vacuum-packed product in step S120 of vacuum-packing the product, and the presence or absence of coating unevenness and the like are confirmed. The surface of the product may be laser irradiated with a 3D scanner. The three-dimensional coordinate data of the surface of the product acquired by the 3D scanner may be converted into predetermined 3D data.
The range in which the paint is applied may be only a portion of the 3D scanner that emits a laser (a portion requiring image analysis), or may be evenly applied to the whole. After completion of the image analysis, the converted 3D data may be used to confirm the presence or absence of a predetermined defect (for example, an analysis defect of the three-dimensional coordinate data portion which could not be acquired). A process may be performed.

In step S140 of processing the result of the image analysis, 3D data analyzed in step S130 of analyzing the surface of the vacuum-packed state is converted into STL data, and a control program of a predetermined machine tool is performed using CAD. It is also possible to make each separately and cut or grind the iron or resin designed mold with a predetermined machine tool.
In addition, after completion of processing, when problems occur in conversion of STL data, mold design by CAD, cutting by CAM, etc. and a desired mold can not be manufactured, the same process may be performed again.

Here, a film printing process of a product image shown in FIG. 2 may be performed in parallel with the above-described manufacturing process of a mold for a product sample.
First, in step S210 of processing an image of a product, of the image data of a state in which the product taken in front of the step S110 of freezing the product is planarly viewed, only a portion necessary for forming a product sample is trimmed or reality is enhanced. For this purpose, the color tone or lightness may be changed.

Next, in step S220 of printing an image of a product on a film, using a predetermined printing plate produced based on the image data generated in step S210 of processing the image of the product, a single layer of 15 to 50 μm in thickness is used. The product image may be gravure printed on a non-oriented polystyrene film (CPS).

Then, after the completion of the above-described production mold for the product sample and the film printing process for the product image, the production process for the product sample shown in FIG. 3 may be performed.
First, in step S310 on the substrate, the film produced in the film printing step of the product image may be laminated with high impact polystyrene (HIPS) having a thickness of 300 to 600 μm, and then fully position molded. According to this process, the image printed on the film can be made to coincide with the desired position of the mold, and the quality improvement of the product sample can be expected.
In addition, endless printing, width fixed position printing, or flow fixed position printing may be performed according to the type of product or the quality of a product sample.

Next, in step S320 of molding the laminate sheet with a mold, it is preferable to use hot plate molding which facilitates in-situ printing of the laminate sheet generated in the printing step S310 on the substrate. You may cut into the size and shape which fit by fitting.
The molding method is not limited to hot plate molding, and may be vacuum molding or vacuum pressure air molding.

As described above, according to the method for manufacturing a mold for molding a product sample in the present embodiment, a predetermined film is formed on the surface of a product (including food via step S110 for freezing the product) in step S120 of vacuum packaging the product. Because it adheres well, it can not only relieve the unevenness of the product surface, close the grooves or gaps on the product, or prevent the generation of shadows due to the unevenness or grooves or gaps, but it also reduces the moisture on the product surface. It is possible to avoid coating and rot of goods. This makes it possible to reduce factors that impede the image analysis of the complex surface shape of the product. That is, since it is easy to apply the paint for laser reflection of a 3D scanner in Step S130 of analyzing the surface of the vacuum packaged state, it is possible to obtain good image analysis results. Therefore, since it is possible to manufacture a mold for molding a product sample that accurately simulates the shape of a product, it is possible not only to significantly reduce the production time of the product sample as compared with the conventional method for manufacturing product samples by skilled workers. Mass production of highly reproducible product samples can be expected. Furthermore, such a product sample may be a three-dimensional molded product including a container body for packaging a product and a lid, and the effect of finding a new application as a product sample can also be expected.

In addition, by performing step S110 of freezing the product prior to step S120 of vacuum-packing the product, it is possible not only to harden liquid soft food (for example, demi-glas sauce such as hamburger), but also by reduced pressure at vacuum packaging. Boiling of food can be prevented in advance. Therefore, an increase in the types of food samples can be expected.

In addition, since the product is a food provided in a packaging container, a liquid or semi-liquid soft food product sample can be easily manufactured. Therefore, it can be expected to sample various kinds of food in a packaged state depending on the shape and packaging method of the packaging container.

In addition, in step S120 of vacuum-packaging a product, the vacuum ultimate pressure during vacuum-packing is 0.05 to 0.2 MPa, which is not only difficult to generate shadows of the product as an obstacle to image analysis; The product can be vacuum packaged in a desired state because the film does not have wrinkles and does not destroy the shape of the soft product. Therefore, by adjusting the vacuum ultimate pressure, it is possible to expect faithful sampling of various foods.

In addition, by using a laminate sheet in which a printed film for lamination is attached to a sheet as a substrate, it is possible to save time and labor for describing the shape and color of a product sample after production, and to significantly reduce the production time of the product sample. I can expect further.

The packaging container used for the above-mentioned product sample is formed by thermoforming a synthetic resin sheet, for example, by sheet forming such as vacuum forming, pressure forming, vacuum pressure forming, double-sided vacuum forming, hot plate forming, etc. It is also good. As the synthetic resin sheet, for example, a polyester resin such as polyethylene terephthalate, a styrene resin such as polystyrene, or an olefin resin such as polypropylene may be used, and a single layer or multilayer sheet may be used. As the resin, for example, use of a foamed resin is preferable because it is lightweight. The thickness of the synthetic resin sheet is not particularly limited, but may be 0.15 to 0.3 mm and is not particularly limited.
