FIG. 2 is a block diagram illustrating functional modules of the service providing device 100 according to FIG. 1 .

Referring to FIG. 2 , the service providing device 100 includes a base paper production unit 101, a printing unit 102, a coating unit 103, and a Thompson processing unit 104.

The base paper production unit 101 produces base paper that serves as a base material for making shopping bags, etc. In one embodiment, the base paper may be produced from a polyurethane film containing polyurethane fibers. A detailed description of this will be provided later.

The printing unit 102 forms a printing layer for printing a developed view on part or the entire outer surface of the base paper produced by the base paper production unit 101 and can perform printing.

The coating unit 103 may form a coating layer by applying a coating liquid to protect the printing layer formed by the printing unit 102.

The Thompson process unit 104 can form a work line on the printed layer on which the coating layer is formed using a Thompson machine or the like.

FIG. 3 is a flowchart showing a process in which the service providing device according to FIG. 1 provides a service for manufacturing and inspecting shopping bags.

Referring to FIG. 3, the process of manufacturing and inspecting a shopping bag may be performed in a process sequence including a base paper production step (S100), a printing step (S200), a coating step (S300), and a Thompson step (S400).

The base paper production step (S100) is a step in which the base paper production unit 101 produces base paper that becomes a base material for making shopping bags, etc.

In one embodiment, the base paper production unit 101 may produce polyurethane film paper containing polyurethane fibers as base paper.

The polyurethane fiber described above is also called elastic fiber and refers to a polymer compound containing 85% or more of polyurethane content. Although the strength of polyurethane fiber is lower than that of other fibers, fabrics made from it have excellent durability and are used in a variety of fabrics, from thin fabrics with good strength to heavy clothing. Polyurethane fiber is the only elastic fiber that stretches well like rubber, stretches more than 6 times, and has good recovery. Compared to rubber bands, polyurethane fiber is not affected by oxidation, sweat, cosmetics, or heat, and does not age. Polyurethane fiber can make even very thin threads, so it is possible to produce microfibers of about 10 dtex (decitex), which is impossible with natural rubber. When mixed with other fibers, sufficient elasticity can be obtained with just a mixing ratio of 5 to 6%. Hygroscopicity is very low, less than 1%, and specific gravity is relatively light at 1.0 to 1.3. In particular, water-soluble polyurethane fiber is made by spinning water-soluble polyurethane resin, and unlike existing polyurethane resins, it can prevent environmental pollution by replacing volatile solvents with water.

Additionally, the polyurethane film paper may be biodegradable polyurethane impregnated with an additive containing phosphorus pentoxide. In one embodiment, phosphorus pentoxide is an anhydride of phosphoric acid, a white crystalline powder produced when phosphorus is burned in sufficient air or oxygen, and can be used as a powerful oxidizing agent. Phosphorus pentoxide is very hygroscopic, and its ability to absorb moisture in the air is much greater than that of concentrated sulfuric acid or calcium chloride, so it is often used as a drying agent and dehydrating agent. Phosphorus pentoxide is a strong oxidizing agent and can act to decompose polyurethane. This allows the base paper to biodegrade and prevent environmental pollution.

Meanwhile, the additive may further include potassium hydroxide (KOH). If potassium hydroxide is further included, it has the effect of efficiently decomposing the polymer urethane in a faster time.

Additionally, in one embodiment, the additive may be coated with natural oil. Since the above-mentioned phosphorus pentoxide contained in the additive can have a strong oxidizing effect, it can exert an anti-oxidation effect by coating the surface with oil.

Meanwhile, in the printing step (S200), the printing unit 102 forms a printing layer for printing a developed view on part or the entire outer surface of the base paper 110. For the printing step, a Gebau six-color printer or a Heidelberg two-color printer can be used. At this time, the base paper may be used as a transparent film, and if necessary, an opaque film or paper may be used.

In one embodiment, the development diagram is based on the user's selection and can be applied in various ways without being limited to any one shape or design.

Additionally, in one embodiment, the printing layer may be formed by the printing unit 102 using a printing method such as gravure printing, flexographic printing, or offset printing.

Additionally, in one embodiment, the printing layer may be a background color, pattern, or pattern, and the pattern may be defined in a broad language that includes pictures, logos, or fonts.

The coating step (S300) is a step in which the coating unit 103 applies a coating liquid to form a coating layer to protect the printed layer printed by the printing unit 102. Coating can be performed on the printed base paper using a coating method or a laminating method to prevent deterioration of the printed material. At this time, the coating layer can be formed in a glossy or matte manner.

FIG. 4 is a flowchart showing the specific process of step S300 of FIG. 3.

Referring to FIG. 4, the coating portion 103 can be formed by laminating a clear film layer on a polyurethane film impregnated with an additive containing phosphorus pentoxide (S310). The clear film layer eliminates the surface curvature of the polyurethane film, thereby reducing light scattering and preventing the contents displayed on the surface of the shopping bag from being distorted when other users view the shopping bag. Additionally, in one embodiment, the clear film layer may be laminated by undergoing electric discharge or plasma discharge treatment. At this time, the wettability and printability of the base paper can be improved compared to before due to electric discharge or plasma discharge treatment.

Additionally, the coating portion 103 can form an antibacterial layer by coating a polyurethane film with hot melt (S320). In one embodiment, the hot melt includes sodium oxide, titanium dioxide, and silicic acid in the above-described antibacterial layer. At this time, sodium oxide, titanium dioxide, and silicic acid must be processed to the minimum nanoparticle size, and the processed particles can be blended to form.

More specifically, the antibacterial layer contains the thermoplastic resin raw material, which is the basic material of hot melt, at a weight ratio of 94 to 98%, the silicic acid processed into nanoparticle size at a weight ratio of 1 to 2%, and the dioxide processed into nanoparticle size. It is formed by coating a hot melt blended with titanium at a weight ratio of 1 to 2% and the sodium oxide processed into nano particle size at a weight ratio of 1 to 2%.

At this time, as an additional explanation, the silicic acid included in forming the antibacterial layer is a general name for a compound mixed with silicon and oxygen or silicon and hydrogen, and is mainly extracted from crude rock minerals in minerals that exist in nature. Silicic acid quickly removes odor-causing substances such as cigarette smoke, food odor, vehicle odor, sulfur dioxide, and carbon monoxide due to its excellent adsorption capacity, and has well-known material properties that are effective in removing bacteria, dust, pollen, and mold.

In addition, the titanium dioxide included in forming the antibacterial layer has well-known material properties such as excellent antibacterial, odor removal, and sterilizing effects due to its high oxidizing power.

In addition, the sodium oxide contained in forming the antibacterial layer is mixed with the silicic acid and the titanium dioxide to interact as a catalyst or co-catalyst, and has a sterilizing and antibacterial effect through the deposition function according to the interaction. It has well-known material properties that exhibit .

Additionally, the coating portion 103 may be formed by laminating a photoreactive layer on polyurethane film. The photoreactive layer may be positioned between the antibacterial layer and the polyurethane film. In one embodiment, the photoreactive layer is formed by applying a zinc oxide component, and zinc oxide has a known material property of removing various contaminants through a catalytic reaction, for example, a redox reaction using light energy.

Specifically, the step of forming the photoreactive layer includes mixing the zinc oxide synthesized into nanoparticle size by a spray pyrolysis device with a volatile solvent, and spraying and applying the volatile solvent to polyurethane film paper using a compression spray nozzle. After the step of spraying and applying the volatile solvent, the volatile solvent is naturally vaporized and the zinc oxide is dried and adsorbed onto the polyurethane film.

Referring again to FIG. 3, the Thompson step (S400) corresponds to a step in which the Thompson process unit 104 forms a work line on the coated printed layer using a Thompson machine or the like. In one embodiment, the work line is a fold line formed in the printing layer by the Thompson process and refers to a line that guides the formation of a shopping bag when the base paper is folded along the fold line.

More specifically, the work line is a part of the work line that is cut off so that the user can easily cut it, and a known cut line or fold line is formed through the first Thompson processing process. At this time, the cut line or fold line may pass through in the form of a dotted line or a straight line.

At this time, it is desirable that all the outer edges, such as the adhesive part or the printing area, be subjected to only a portion of the Thomson processing according to the manufacturer's intention, without forming a cut line or fold line through the first Thomson processing process.

The Thompson process unit 104 may perform a secondary Thomson processing process in which the coated printing paper is secondarily Thomson processed according to the shape of the development diagram. In one embodiment, the secondary Thomson machining process can process the adhesive portion and the outermost edge of the print area.

Before the Thompson step begins, corrugated cardboard may be laminated on the base paper and then the Thompson process may be performed. At this time, the base paper and corrugated cardboard are laminated using an adhesive, and a lamination machine is used. In one embodiment, the adhesive is a water-soluble adhesive that uses polyvinyl acetate (polyvinyl acetate), which has excellent water resistance, as a base material, and polyvinyl pyrroli to prevent a decrease in viscosity due to water solubility of polyvinyl acetate and to assist adhesiveness. It may have a mixed composition containing polyvinylpyrrolidone, glycerin or ethylhexyglycerin to suppress moisture absorption and assist adhesion, and a tackifier resin to increase adhesion. More specifically, the adhesive can be mixed with 10 to 30 parts by weight of polyvinylpyrrolidone, 1 to 10 parts by weight of glycerin or ethylhexyglycerin, and 1 to 20 parts by weight of tackifier resin, based on 100 parts by weight of polyvinyl acetate. there is.

Additionally, in one embodiment, the tackifier resin may be at least one of rosin, rosin derivatives, terpenes, aliphatic resins, phenol resins, xylon resins, ketone resins, and coumarone-indene resins.

Additionally, the Thompson process unit 104 can inspect whether the work line formed in the Thompson step (S400) has been formed precisely. This will be described in detail later with reference to FIG. 5 .

FIG. 5 is a flowchart showing the specific process of step S400 of FIG. 3.

Referring to FIG. 5, the Thompson process unit 104 determines a work line that matches the shopping bag after the Thompson process (S410).

In the database (not shown) of the service provision device 100, the pressing force applied to the base paper, the pressing frequency, and the work line are matched and stored in advance. The service providing device 100 searches a database (not shown) for the pressing force, pressing frequency, and work line applied to the base paper matching the shopping bag. For example, the pressurizing force of 100 tons, 4/sec applied to the base paper, and the expected fold line to be printed on the shopping bag unfolding diagram can be matched and stored in the database in advance.

Additionally, the Thompson process unit 104 receives a completed image matching the above-described work line (S420).

The Thompson process unit 104 can determine a finished image through the inspection terminal 200 that allows the work line generated after the Thompson process to be viewed from all angles. In one embodiment, the finished image may be created as a 360° VR (Virtual Reality) image. The user terminal 300 is an app screen or web that displays a 360° VR (Virtual Reality) image that allows you to view the work line created after the Thompson process from all angles through the user interface provided by the service providing device 100. The screen can be displayed. When the user sets the angle he or she wants to view through the input interface device of the user terminal 300, the user terminal 300 may display an image that matches the set angle.

Additionally, the Thompson process unit 104 determines the error rate for the completeness of the Thompson process using the completed image (S430).

The Thompson process unit 104 may determine an error rate, which is an expectation for the possibility that the work line generated by the Thompson process does not match the work line input and matched in advance for the shopping bag.

Figure 6 is a flowchart showing the specific process of step S430 of Figure 5.

Referring to FIG. 6, the Thompson process unit 104 selects an artificial neural network that matches the family business history, pressurization frequency, and work line (S431).

In one embodiment, a plurality of artificial neural networks that match the combination of pressing force, pressing frequency, and work line are trained and provided in advance. For example, the Thompson process department 104 may select an artificial neural network that matches the expected fold line printed on the development diagram of a specific shopping bag to be delivered, 110 tons, 3.8/sce.

Additionally, the Thompson process unit 104 inputs the finished image matching the above-described work line as an input value to the artificial neural network, and obtains an error rate matching the completeness of the Thompson process from the artificial neural network (S432).

For example, when an artificial neural network that matches the combination of 110ton, 3.8/sec and the expected fold line printed on the development diagram of a specific shopping bag to be delivered is selected and a completed image of the shopping bag is received from the inspection terminal 200, Thompson Gong The government 104 can input the completed image as an input value to the selected artificial neural network. In one embodiment, the artificial neural network generates a feature vector by linearly connecting a plurality of feature maps obtained from the final layer of a CNN (Convolutional Neural Network) with respect to the completed image, and inputs the feature vector as an input value to the Random Forest. And the error rate for the completeness of the Thompson process can be obtained with the output value of Random Forest. In one embodiment, the completeness of the Thompson process may be a 2D image showing expected fold lines printed on the developed view of a specific shopping bag to be delivered.

In addition, in one embodiment, the error rate is calculated by converting the finished image into a 2D image (two-dimensional image) and comparing it with the expected fold line printed on the developed view of the specific shopping bag to be delivered, and calculating the total of the lengths that do not match the developed view of the specific shopping bag to be delivered. It can be defined as the value divided by the total length of the expected printed fold lines.

In addition, the error rate of the Thompson process is determined by the degree to which the image of the expected fold line printed on the development plan of the specific shopping bag to be delivered does not match the determined finished image. The higher the degree of mismatch, the higher the error rate. high.

At this time, the Tomseung process unit 104 uses the inspection terminal 300 described above to determine the position of the expected fold line printed on the development drawing of the shopping bag, the length of the expected fold line, and the work line generated by the Thompson process during the process for manufacturing the shopping bag. Information on the length, location of the work ship, etc. can be obtained.

An artificial neural network can be created through machine learning using a learning data set that includes training data labeled with training completeness in a training complete image. For example, in the case of learning an artificial neural network that matches the combination of 110ton, 3.8/sec and the expected fold line printed on the development diagram of a specific shopping bag to be delivered, 110ton is used in the Thompson process to generate the fold line of a specific shopping bag to be delivered. Learning data can be generated by selecting images with a low error rate among the completed images of the work line formed by pressurization at a frequency of 3.8/sec, and labeling the selected images with the completeness of the Thompson process. For learning artificial neural networks, CNN (Convolutional Neural Network) and Random Forest can be used.

The Thompson process unit 104 may provide the user terminal 300 with an error rate determined for completeness. Through this, the user can determine the optimal pressing force and pressing frequency to minimize the error rate for a specific shopping bag to be delivered.
