JP5947106B2 - Manufacturing method of reusable product protection material - Google Patents

Description

The present invention particularly relates to a method for producing a reusable product protective material having excellent handling properties.

  As a conventional product protection material in a product package, wood, wood, paper, or processed polystyrene is typically used, but most is disposable.

  In the conventional mold molding technology, the method of liquefying the molding material, pouring it into the mold, solidifying it and mass-producing it is general, but materials such as wood and cloth have limited stretchability at the time of molding. In the case of molding a non-woven fabric, a different molding method is used in which a different molding method is performed in which vacuum molding is performed after preforming with a shallow drawing in order to fix the shape. (Patent Document 1)

  Also, as a method of heat-molding wood trays using glue material, there is also a method of trimming the periphery of the plate for the purpose of improving the appearance of the product after taking one mold with a single wood plate and heat-molding . (See Patent Document 2)

The present applicant has invented an environment-friendly product protection material that can be easily reused at home after using the product protection material. In this invention, after the paste material is attached to the woven fabric product by spraying, it is sandwiched in a product mold to be molded, and is then made into a high-temperature dryer and solidified and molded into a product protective material. After that, when the role as a product protective material is finished, it is washed at home, and the glue material is removed and used as an original woven fabric product.

  However, the above conventional method has the following problems that must be solved. Most of the conventional product protection materials used are made on the premise of being disposable, and are incinerated as combustible waste, which emits carbon dioxide and causes global warming.

  The non-woven fabric molding method is a processing method that aims to keep the shape of the finished product as long as possible. It can be easily released from the solidified molding state and incorporated into the solidified molding process of the present invention for reuse. Has a problem.

  In the wood tray molding method, a single wood plate is used to make a mold, and trimming is performed around the tray at the final stage to make it look good. In most cases, a plurality of molds are formed, and a woven fabric product is used as a molding material for the purpose of reuse after use as a product protection material. Therefore, trimming finish is not preferable at the end.

  In the prior patent relating to the present applicant, a certain amount of water is mixed with the powder used as the raw material of the paste to prevent the concentration of the paste from being increased, and then the raw material of the paste is sprayed onto the woven fabric product, However, there is a problem that the time has to be shortened for mass production within a certain period.

The present invention develops a method for manufacturing a reusable product protection material , and in order to cope with mass production, by changing the raw material, shape, and adhesion method of the paste material, ensuring a stable concentration of the paste material and bonding By improving the power and reducing the amount of water used, the drying process that takes the most time in the production process is greatly shortened to solve the above-mentioned problems.

  The material to be processed into a sheet is an organic material, and the adhesive strength is guaranteed. Wheat, rice, corn, sweet potato, potato, konjac rice, seaweed and the like are preferable.

  With regard to the raw material of the glue material, use of wafers and rice paper, paying attention to the fact that when it is processed into a sheet, it has already been pre-gelatinized, and when moisture is added, adhesive strength can be obtained instantaneously and adhesive strength is strong. .

  Further, when the product of the present invention is used as a food product protective material for food, the fact that the paste material is made from food gives a great sense of security to consumers. Oblates and rice paper are mass-produced foods, but hygiene management, thickness and weight are ensured uniformly, and these aspects are significant advantages as raw materials for paste.

  The strength of the adhesive force is adjusted by using one to a plurality of sheets in accordance with the thickness of the woven fabric product to be solidified. In particular, the portion to be hardened is overlaid with more raw material of the glue processed into a sheet. The strength and weakness of the woven fabric product makes it easy to fold it into a box package for storing the product, improving work efficiency.

  In addition, by changing the raw material and shape of the paste material, it is possible to restore and restore the original product even if it is indented into the product storage part.

  The molding equipment used to mold the product protection material is an individual male mold, a female mold created by punching multiple product molds on a single plate, and a plurality of vent holes to place them. This tray is provided.

  Using these molding equipment, solid materials such as towels, towels, clothing, and cloth bags, which are woven fabric products, are solidified and processed into product protection materials.

  The final process of solidification molding is drying, but the method of natural drying, air drying, and heat drying is selected according to the material and production amount of the woven fabric product.

  The temperature for drying by heating is adjusted depending on the material and the humidity and temperature at that time for imparting the shape, but a temperature range of 50 ° C. to 150 ° C. is preferable except for some materials.

  The shape of the male mold is obtained by cutting the product stored in the product storage package into two halves vertically or two halves, and the shape of the cut surface is continuous to the male cross section within a thickness range of 1 mm to several tens of mm. Add the male shape to the height. In addition, by making each male mold independent, fine adjustments can be made to the molding material with poor stretchability, ensuring the depth of the product storage section.

  By changing the raw material of the paste material from powder to a sheet processed, the amount of water given to the raw material of the paste material can be drastically reduced, and the exudation of excess paste material that occurs during high-temperature drying is eliminated. As a result, the material for the male mold has traditionally focused on the material that absorbs moisture and excess glue from the woven fabric product, but the present invention has made it possible to select a variety of mold materials for molding. .

  The shape of the female mold is a punching mold in which margins are provided at both ends of the female mold so as to be placed on the tray, and the woven fabric product is inserted into the same shape of the female mold as a male mold from above. At this time, the woven fabric product is exposed from 50 to 80% of the molding depth from the bottom of the female mold and solidified and molded three-dimensionally in the suspended state, thereby preventing the woven fabric product from wrinkling and shortening the drying time. . Further, it is possible to provide a groove on the inner wall of the punched female mold as a wrinkle reducing measure.

  The tray has multiple vents on all sides and a depth corresponding to the size of the male mold, smoothing the air flow from each side during drying, reducing drying time and exposing it. Prevent deformation of woven fabric products.

  The three-dimensional solidification molding process of the product protection material is done by placing the raw material of the paste processed into a sheet on the woven fabric product in a three-dimensional solidification molding process, and spraying, painting, etc. Apply uniformly to the sheet.

  Although the amount of water varies depending on the area and weight of the sheet, an appropriate amount of the band can obtain an adhesive force with a weight that is 1 to 20 times the weight of the sheet. If air bubbles are formed on the moisture-containing sheet, it is sandwiched between woven fabric products and then crushed with a roller or the like from the top of the woven fabric product. Prevent damage.

  In addition, a steaming method can be used as a separate method for providing moisture. The sheet is sandwiched between the three-dimensionally solidified parts of the woven fabric product, and one to a plurality of sets are placed in a steamer and steamed. A stable adhesive strength can be obtained when the temperature is about 90 ° C to 100 ° C. The steaming time is adjusted by the thickness of the woven fabric product, the number of sheets used, and the amount of steam, but it is possible to give an appropriate amount of moisture in about 1 to 10 minutes. If the sheet loses gloss and deforms and changes into a gel with adhesive strength, it is determined that an appropriate amount of moisture has been given. If bubbles appear, crush them with a roller or the like from above the woven fabric product.

  Spread the woven fabric product that has been moistened and sandwiched on the sheet onto a female mold made by punching multiple product molds on a single plate placed on the tray. Fit into the female mold and fix the fabric product. In this state, a suitable drying method is selected from natural drying, blow drying, and heat drying, and solidification molding is performed. The drying temperature is adjusted by the material and the humidity and temperature at that time for imparting the shape, but a temperature range of 50 ° C. to 150 ° C. is preferable except for some materials.

The present invention is a product protective material that can be reused as an original woven fabric product by removing the glue by washing with a hand after washing the product protective material after finishing the role in water or lukewarm water and washing with a washing machine . A manufacturing method is provided.

  The present invention improves the raw material, shape, and adhesion method of the material used for the paste material, so that the drying time is less than one-half that of the applicant's conventional method, and the production efficiency is greatly improved. It is now possible to create materials such as metal, plastic, and wood. Therefore, the range of use has expanded to various packaged goods.

  If it is limited to towels, it can be flexibly adapted to the product that protects the thickness and size, and when used as a product protection material for lightweight products, use a towel cloth with a rough texture to show the product clearly. For heavy items, thick towels with woven fabric are used to protect the item to reduce deflection. In addition, colors and other designs can be designed along with the stored products, and even if they are displayed in the same place as the same type of products, they can produce a unique luxury and have a great impact on consumers.

  In addition, as society matures, many people enjoy eating meals, such as the shape and color of tableware, and the surrounding accessories. Therefore, using a placemat printed with a design that matches the color of the tableware, making a product protective material and giving it as a gift together with the tableware will also play a role in sales promotion.

  In addition, there are an increasing number of companies working on new business developments that have been researched and reinvented what has been considered as industrial waste and those that have been discarded so far to find new value and increase profits. Environmentally friendly product protection materials made from products can also deliver a message directly to consumers about the company's environmental spirit and philosophy. I think that it is even more meaningful when the zero emission proposed by the United Nations University is in the corporate philosophy.

  At the same time, the use of disposable merchandise protectors is unavoidable for merchandise protection, but many senders think that they do not want to put the burden of disposing of garbage on the recipient of the gift.

  The thickness of the oblate 12 is not limited as long as the adhesive force is secured, but as an example, one to a plurality of sheets depending on the thickness of the woven fabric product 3 that solidifies and molds one sheet of 16 μm to 50 μm. The parts that are used in a superposed manner, especially the hard finish, are made hard by strengthening the adhesive force of the woven fabric product 3 by stacking more of the oblate 12.

  The method of three-dimensionally solidifying and molding the product protective material 9 is to place the wafer 12 on the three-dimensional solidified and molded position on the woven fabric product 3, and uniformly spray the moisture on the wafer 12 by spraying or painting. give.

  Although the amount of water is adjusted depending on the area and weight of the wafer 12, the appropriate amount zone can obtain a stable adhesive force that is 1 to 20 times the weight of the wafer 12. If air bubbles are formed in the wafer 12 due to moisture, the wafer 12 is sandwiched between the woven fabric products 3 and then crushed with a roller or the like from the top of the woven fabric product 3 and solidified and formed on the surface of the woven fabric product 3. Prevents air bubbles from appearing and damaging the appearance.

  In addition, a steaming method can be used as a separate method for providing moisture. The wafer 12 is sandwiched between the woven fabric products 3, and one to a plurality of sets are placed in a steamer and steamed. At this time, a stable adhesive strength can be obtained when the temperature is about 90 ° C to 100 ° C. The steaming time is adjusted by the thickness of the woven fabric product 3, the number of wafers 12 used, and the amount of steam, but it is possible to give an appropriate amount of water in about 1 to 10 minutes. If the oblate 12 loses the gloss seen when it is a sheet and deforms and changes to a gel with adhesive strength, it is determined that an appropriate amount of moisture has been given. If bubbles appear, crush them with a roller or the like from above the woven fabric product 3.

  The molding equipment used to solidify and mold the product protection material 9 is an individually independent male mold 1, a female mold 4 created by punching a plurality of product molds on a single plate, and a place for mounting these. The tray 7 is provided with a plurality of pores 8. Using these, the woven fabric product 3 is solidified and molded into the product protection material 9.

  The shape of the male mold 1 is such that the product stored in the product storage package 11 is cut into two equal parts vertically or two equal parts, and the shape of the cut surface is within the range of 1 mm to several tens of millimeters. Add to the cross-section and raise the male mold 1. This is because the product storage section 10 has a molding depth D when the product protection material 9 is created with the woven fabric product 3.

  The shape of the female die 4 is a punching die 5 having a margin of 20 mm or more on one side at both ends of the female die 4 for placement on the tray 7. Further, it is possible to provide a groove on the inner wall 6 of the punched female die 4 as a measure for reducing wrinkles of the woven fabric product.

  The tray 7 has a plurality of ventilation holes 8 and depths according to the size of the male mold 1 on all surfaces, and the air flow from each surface direction is smooth during drying to shorten the drying time. The deformation of the exposed woven fabric product 3 is prevented.

  The fabric product 3 in which the wafer 12 is moistened and sandwiched is spread on the female mold 4 made by punching a plurality of product molds on a single plate placed on the tray 7, and the fabric product 3 is spread from the top. The male mold 1 is vertically inserted into the same mold of the female mold 4 with the arc-shaped product storage portion molding surface 2.

  At this time, the woven fabric product 3 is exposed from the bottom of the female mold 4 at a depth H of 50 to 80% of the molding depth D and solidified and molded three-dimensionally in a suspended state, thereby forming the woven fabric product 3. Prevent selfishness.

  Then, an appropriate drying method is selected from natural drying, blow drying, and heat drying, and solidified and molded to produce the product protection material 9.

  The drying temperature is adjusted depending on the material and the humidity and temperature during processing to give the shape, but a temperature range of 50 ° C. to 150 ° C. is preferable except for some materials.
