Description

METHOD FOR FILLING AEROSOL PRODUCT CONTAINER FIELD OF THE INVENTION [0001]

The present invention relates to an aerosol product storage container filling method, and more particularly, to an aerosol product storage container capable of minimizing a defective rate by filling a storage container with a raw material and a gas in a fixed amount and a constant pressure, And a filling method.

An aerosol product refers to a product that fills a container in which a raw material is stored with a compressed gas and fires the raw material by compression of the compressed gas. Aerosol products are easy to use and can spray a wide range of raw materials at a constant concentration, and they can be used for cosmetics such as mist, cleansing foam, hair spray, line spray, household products such as insect spray, paint spray, It is widely applied to industrial products such as spray.

When the aerosol product is manufactured, the storage container is filled with the raw material and the gas in a sealed state. In this process, the inside of the storage container becomes a high pressure state and leakage of the raw material or gas may occur. Such leakage of the raw material or gas may cause product failure. Also, when the raw material is supplied, the raw material is not filled in a predetermined amount, or if the gas is not filled with the positive pressure when the gas is supplied, the product may be defective. Therefore, it is necessary to develop a technology that can minimize the defect rate of the product by determining whether the raw material is quantitatively determined, whether the filling gas is filled in the static pressure, and whether the storage container is leaked.

FIG. 1 is a block diagram illustrating a method of filling a storage container 210 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of a cover 230 according to an embodiment of the present invention, This is a reference diagram for explaining the process.

Referring to FIG. 1, a method of filling a storage container 210 according to an embodiment of the present invention includes a step of supplying a storage container 210, a step of placing a cover 230, a step S200 of removing a foreign substance, (S 500), a raw material supply step (S 600), a gas supply step (S 700), a storage container (210), a storage container (210) ) Weight measurement step (S800).

The storage container 210 is formed in a cylindrical shape and has a space therein, and an opening may be formed on the top surface thereof. The inner space of the storage container 210 may be filled with a raw material and gas to be described later.

The storage container 210 is supplied through a conveyor belt (S100), and the cover 230 is placed in the opening of the supplied storage container 210 (S200). The cover 230 may be formed in a circular shape corresponding to the opening of the storage container 210 and a nozzle 250 may be coupled to a part of the cover 230 through the cover 230. A portion of the nozzle 250 protrudes to the top of the cover 230 and the remaining portion of the nozzle 250 is located inside the storage container 210 and the remaining portion of the nozzle 250 is connected to the bottom of the storage container 210 As shown in FIG.

Next, the interior of the storage container 210 is cleaned by blowing air into the storage container 210 (S300). Specifically, as air flows into the storage container 210 and flows out of the storage container 210, foreign substances inside the storage container 210 are discharged to the outside of the storage container 210 together with air. Accordingly, the foreign matter inside the storage container 210 is removed, and the defect that the nozzle 250 is clogged by the foreign substance can be removed.

Next, the storage container 210 and the cover 230 may be combined (S400). The coupling of the cover 230 and the storage container 210 can be combined by an external pressing force. 2, protrusions may be formed along the outer periphery of the cover 230. As the protrusions of the cover 230 are pressed against the outer periphery of the opening of the storage container 210, The protruding portion of the protrusion 230 is fixed.

Next, the interior of the storage container 210 is formed in vacuum (S500). Specifically, the vacuum inside the storage container 210 may be formed by sucking air inside the storage container 210 through the nozzle 250 coupled to the cover 230. As the interior of the storage container 210 is formed in vacuum, filling of gas and raw material to be described later can be performed.

In addition, by sucking air with a strong suction force, fine dust inside the storage container 210 can be sucked, thereby minimizing the occurrence of product defects.

Next, the raw material is supplied into the storage container 210 (S600). Specifically, the raw material is supplied into the storage container 210 through the nozzle 250 coupled to the cover 230. Since the inside of the storage container 210 is formed in vacuum, the supply of the raw material can be smoothly performed. At this time, the raw materials may be chemicals such as cosmetics (cleansing foam, mist, sun spray, etc.), paint and the like.

Meanwhile, the raw material may be injected into the storage container 210 before the storage container 210 and the cover 230 are coupled (S300). In this case, the process of forming the interior of the storage container 210 in vacuum (S400) may be omitted.

Next, the gas is supplied into the storage container 210 (S700). Specifically, gas is supplied into the storage container 210 through the nozzle 250 coupled to the cover 230. At this time, the gas may be nitrogen gas, LPG, isobutane, carbonic acid, or hydrogen.

Next, a step S800 of measuring the weight of the storage container 210 may be further included. Referring to FIG. 3, when the measured weight of the storage container 210 is determined to be less than a predetermined weight, the raw material is additionally supplied to the storage container 210. When the weight of the storage container 210 is less than a predetermined weight, it is determined that the product is a product failure that is less than the display weight. At this time, when it is determined that the product is defective, the raw material is additionally supplied to the storage container 210, and the weight of the storage container 210 to which the raw material is supplied is measured again, It is possible to minimize the defective product by shipping the product as a normal product.

Meanwhile, the filling method of the storage container 210 according to the present invention further includes a step S900 of measuring a pressure inside the storage container 210 after the step S800 of measuring the weight of the storage container 210 . Referring to FIG. 4, when the measured pressure inside the storage container 210 is judged to be less than a preset pressure, the gas is additionally supplied to the storage container 210. If the pressure inside the storage container 210 is less than a predetermined pressure, the raw material may not be discharged to the outside at an appropriate level during use of the product, resulting in a product failure that is less than the service life of the product. If the pressure is lower than the predetermined pressure, it is determined that the product is defective. At this time, if it is determined that the product is defective, the gas is further supplied to the storage container 210, the pressure of the storage container 210 to which the gas is supplied is measured again, If it is measured, it is judged that it is a normal product and the product is shipped, so that the defective product can be minimized.

5, the filling method of the storage container 210 according to the present invention is characterized in that after filling the raw material and the gas into the storage container 210, the gas or raw material in the storage container 210 is leaked (S1000). It is possible to minimize the occurrence of product defects by prohibiting the shipment of the product when the internal substance of the storage container 210 is leaked by determining whether or not the storage container 210 is leaked.

At this time, whether or not the gas or raw material of the storage container 210 is leaked can be confirmed by passing the storage container 210 through a water tank. 6, the water tank may include a water tank main body 710, a rail 730, and a holder 750. The water tub main body 710 is composed of an outer wall and an inner space, and the upper portion is opened. At this time, hot water can be carried in the space inside the water tub main body 710.

A rail 730 may be provided along the longitudinal direction of the water tank on the water tank main body 710, and a plurality of rails 730 may be provided. The rail 730 may be provided with a holder 750 that moves along the rail 730. The holder 750 fixes the cover 230 of the storage container 210 and the storage container 210 fixed to the holder 750 is immersed in the hot water of the water tank 710. More specifically, the holder 750 is coupled to the rail 730 at a height such that most of the storage container 210 is immersed in the hot water of the water tank 710 when the storage container 210 is coupled to the holder 750 The holder 750 moves along the rail 730 so that the storage vessel 210 moves along the water bath 710 while being immersed in hot water and bubbles are formed around the moving storage vessel 210. [ It is possible to determine whether or not the storage container 210 is leaking depending on whether the storage container 210 is leaking or not. If bubbles are generated outside the storage container 210, the storage container 210 may be damaged or the storage container 210 and the cover 230 may not be properly coupled to each other. At this time, it is common for the inspector to check the occurrence of bubbles with the naked eye.

In another embodiment, the water tank may further include an inspection camera 770. Whether or not the bubble is generated can be determined by detecting the bubble portion by photographing the storage container 210 immersed in the water tank with the inspection camera 770. The inspection camera 770 photographs the storage container 210 in synchronization with the movement speed of the holder 750 provided on the rail. Accordingly, a predetermined portion of the image taken every time is taken every storage container 210 as shown in FIG. The photographed image is analyzed by the inspection camera 770 to determine whether a bubble has been generated or transmitted to the control unit 10, and the controller 10 can analyze the image to determine whether a bubble has occurred.

Whether or not the bubble is generated is determined by calculating the amount of change in the luminance within the dotted line, which is an area previously set from the photographed image. The predetermined area may be defined between the upper part of the storage container 210 and the water surface. The reason for the leakage is that the nozzle portion on the upper part of the storage container 210 and the lid and the coupling portion of the storage container 210.

When a bubble is generated, the luminance change is larger at the boundary between the bubble and water, and therefore, the luminance variation is larger than the other portions. Therefore, if the difference in luminance values of neighboring pixels is calculated only within the dotted line area, if the luminance variation is larger than a certain standard, if it is determined that the bubble is generated, the calculation amount can be reduced and the accurate result can be obtained will be. At this time, the constant reference of the luminance change amount may be a luminance change amount outside the boundary of the dotted line portion (inspection region) with reference to the dotted line portion (inspection region). Specifically, when the luminance change amount in the dotted line portion (inspection region) is larger than the luminance change amount outside the dotted line portion (inspection region) based on the boundary of the dotted line portion (inspection region), it is determined that the bubble has occurred. The inspection camera 770 may be installed close to the storage container 210, specifically, in a separate transparent container, and may be introduced into the water in the water tank to photograph the storage container or may be configured with an underwater camera.

At this time, the temperature of the water in the water tank may be 70 ° C to 80 ° C so that bubbles can be easily confirmed. This is to prevent the risk of leakage or explosion even if the final product is left in a parked vehicle in the summer.

Also, the time during which the storage container 210 passes through the hot water carried by the water tank 710 may be 3 minutes to 5 minutes in consideration of the expansion time of the gas.

Next, a label is attached to the outside of the storage container 210, and the product is shipped by individually packing the storage container 210.

As described above, according to the present invention, it is determined whether the product satisfies the shipping specification by measuring the weight of the storage container 210, measuring the leakage of the storage container 210, and measuring the inner pressure of the storage container 210, By shipping only products that meet the specification, the defective rate of the shipped products can be minimized.

[ The size of the storage container 210 is determined by the infrared sensor. In addition, the control unit 1 can control the kind of the raw material and the gas to be supplied according to the size of the storage container 210 according to preset data. Accordingly, it is possible to minimize the inconvenience of changing the operation mode of each device depending on the size of the storage container 210, the raw material, and the kind of the filling gas.

The control unit 1 receives the image photographed from the inspection camera 770 installed in the leakage measuring device 90 and can determine whether a bubble has occurred.
