Description

The manufacturing method and manufacturing apparatus of a three-dimensional mask pack TECHNICAL FIELD

The present invention relates to a method and apparatus for manufacturing a three-dimensional mask pack, and specifically, a three-dimensional mask pack with improved ease of use can be manufactured through a process in which the fabric is attached after the cosmetic is applied in an unfolded state. It relates to a manufacturing method and manufacturing apparatus of a three-dimensional mask pack.

In general, people have an instinctive desire to look beautiful. In order to satisfy these needs, women in particular use various types of cosmetics for their faces and the like.

Cosmetics include products such as foundation and cream, which are delivered to the body skin such as the face and used to decorate the face beautifully, as well as packs and sheets made up of ingredients that can be absorbed into the skin to improve the skin itself to make it healthy and smooth. includes products of

Among these, the mask pack may have a form impregnated with a liquid substance capable of realizing a skin moisturizing effect or a skin soothing effect, and the user attaches the sheet to an appropriate part of the face, and the substance is sufficiently absorbed into the skin After a certain amount of time has elapsed, it is used in a way that the sheet is removed from the face. Such a sheet is manufactured in a form in which a material is wetted on a thin surface, and may be manufactured in a shape corresponding to the face for user's convenience.

However, since the conventional mask pack is composed of a single sheet, when it is disposed on the entire face having a three-dimensional curved shape, wrinkles or sagging partially occur, so that it cannot be uniformly adhered to the entire face. Accordingly, there was a problem in that it was not possible to uniformly supply cosmetics and the like to the entire face from the mask pack.

Referring to FIG. 2 , the manufacturing apparatus 200 may include a transfer unit 210 , an application unit 220 , an attaching unit 230 , a fusion unit 240 , and a cutting unit 250 .

The transfer unit 210 may transfer the fabric to the application unit 220 , the attaching unit 230 , the fusion unit 240 , and the cutting unit 250 . For example, a spool on which a fabric is wound is disposed on one side of the transfer unit 210 , and it may be implemented to transport the fabric drawn out from the spool. The transfer unit 210 may include at least one electrically driven transfer roller and a control module for controlling the driving of the transfer roller. However, this is an example, and the transfer unit 210 may be implemented using various driving means.

The applicator 220 may apply cosmetics to one surface of the fabric delivered from the transfer unit 210 . For example, the applicator 220 may evenly spray the cosmetics through a spray nozzle or the like, so that the cosmetics are evenly applied to the application surface of the fabric. However, this is an example, and the applicator 220 may apply cosmetics through various methods.

In an embodiment, the applicator 220 may be implemented to divide one surface of the fabric into an application area for cosmetics and a non-applied area, and to apply the cosmetics only to the application area.

The contact part 230 may be attached so that one side of the fabric 400 to which the cosmetic is applied (particularly, the surface to which the cosmetic is applied) overlaps. For example, the contact part 230 may fold the fabric along the direction in which the cosmetic-coated fabric is transported through the transport unit 210 . The contact part 230 may include a fixing member for fixing a center line in the longitudinal direction of the fabric, which is a standard for folding, and a folding member for folding a left region or a right region based on the center line of the fabric. However, this is an example, and the contact part 230 may be implemented using various folding means.

For example, the fusion of the fusion unit 240 may be performed through ultrasonic fusion. To this end, the fusion unit 240 may include a fusion plate for generating ultrasonic waves and a contact blade for pressing the bonded fabric downward. However, this is an example, and the joint 130 may be formed through bonding through an adhesive or external heat bonding.

The cutting unit 250 may cut the attached fabric to correspond to the shape of the three-dimensional mask pack 100 . For example, by cutting the joint 130 , the separating part 140 , and the cutout 150 according to the shape of the left face part 110 or the right face part 120 of the three-dimensional mask pack 100 , the contacted fabric The three-dimensional mask pack 100 may be separated from the . Also, for example, the cutting of the cutting part 250 may be divided into a primary cutting for cutting the cutting part 150 and a secondary cutting for cutting the joint 130 and the separating part 140 and performed sequentially. . The cutting unit 250 may be implemented through various cutting means, such as a laser device or a perforation device.

3 shows a manufacturing method of a three-dimensional mask pack according to an embodiment of the present invention, and FIGS. 4 to 6 show a manufacturing process according to the method of FIG. 3 .

More specifically, FIG. 4 shows the manufacturing process of the application step, FIG. 5 shows the manufacturing process of the fabric stacking step and the seam forming step, and FIG. 6 shows the manufacturing process of the cutting step.

Referring to FIG. 3 , the manufacturing method 300 may include a fabric providing step (S310), a cosmetic application step (S320), a fabric contacting step (S330), a joint forming step (S340) and a cutting step (S350). have. The method 300 may be performed by the manufacturing apparatus 200 described above with reference to FIG. 2 , but this is exemplary and not limited thereto.

First, in step S310 , the fabric 400 as a material of the three-dimensional mask pack 100 may be provided. For example, the fabric 400 may be withdrawn from the spool on which the fabric 400 is wound, and the drawn fabric 400 may be provided according to the driving of the transfer unit 210 . Accordingly, the fabric 400 may be implemented to be sequentially provided for processing such as cosmetic application, fabric contact, joint formation and cutting by a predetermined length.

The fabric 400 may be made of at least one material, and may be made of a material that can be fused through ultrasonic welding while the fabric 400 is in contact. For example, the fabric 400 is polyester (PS), polyethylene (PE), low density polyethylene (LDPE), high density polyethylene (HDPE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET) ), polyethylene terephthalate glycol (PETG), polycarbonate (PC), polyacrylate, polystyrene, acrylonitrile butadiene styrene (ABS), nylon (Nylon) 　 or a combination thereof, However, the present invention is not limited thereto.

In one embodiment, the fabric 400 may include an absorbent layer and a waterproof layer. For example, the waterproof layer may be made of a waterproof material, and the absorbent layer may be made of an absorbent material, and may be configured to be disposed above the waterproof layer. That is, it may be configured in the order of the absorbent layer and the waterproof layer from the top to the bottom of the fabric 400 . In this case, the waterproof layer is preferably made of a material capable of maintaining breathability while blocking the outflow of the cosmetic, but is not limited thereto. Accordingly, after the cosmetic is applied to the absorbent layer located on the upper portion of the fabric 400, when the fabric 400 is contacted, a waterproof layer is disposed on the outside of the bonded fabric 500, and an absorbent layer coated with a cosmetic is disposed on the inside It can be implemented as much as possible.

Through this, it is possible to manufacture the three-dimensional mask pack 100 in which the cosmetic material is not absorbed on the outer surface and the cosmetic material is absorbed only on the inner surface, and the cosmetic material absorbed on the inner surface moves to the outer surface of the three-dimensional mask pack 100 leakage can be prevented.

In step S320, a cosmetic may be applied to one surface of the fabric 400 (refer to FIG. 4). Here, the cosmetic applied or coated on the fabric 400 refers to a substance delivered to the skin for health or beauty, for example, wrinkle improvement, skin whitening, UV protection, anti-aging, It may include skin active ingredients such as moisture supply, elasticity increase, prevention and treatment of skin diseases, and in addition, if it is a component that can provide an effective effect to the skin, the ingredients, functions, uses, etc. are not particularly limited.

Step S320 may be performed by applying the cosmetic to at least a partial area of one surface of the fabric 400 . For example, the applicator 220 divides one surface of the fabric 400 into a first region 410 that is a cosmetic application region and a second region 420 that is a cosmetic non-applied region, and the first region 410 . It may be implemented so that only the cosmetic is applied.

Here, the first region 410 is a central region having a predetermined width in the longitudinal direction of the far end 400 , and may form left-right symmetry with respect to the center line of the far end 400 , and the second area 420 is the first It may mean an outer peripheral area of the area 410 .

Through this, cosmetics are applied to the area where the eye cutout 152, nose cutout 154, and mouth cutout 156 that are in close contact with the central area of the face of the three-dimensional mask pack 100 are formed, and the ear cutout By preventing the cosmetic material from being applied to the region where 158 is formed, it is possible to prevent excessive waste of the cosmetic material in the manufacturing process.

In addition, according to one embodiment, in consideration of the process in which the fabric 400 is contacted in step S330 , cosmetics are applied only to a partial area on the left or right side based on the center line of the fabric 400 , and the fabric 400 . As this contact occurs, the cosmetic applied to the left or right region of the fabric 400 may be transferred to and applied to the right or left region. That is, for example, a region corresponding to the left face part 110 of the three-dimensional mask pack 100 among one surface of the fabric 400 (in particular, the eye cutout 152 , the nose cutout 154 , and the mouth cutout) The cosmetic is applied only to the area where the 156 is formed), and as the fabric 400 is contacted, the cosmetic is applied to the area corresponding to the right facial part 120 . However, this is an example, and according to the embodiment to which the present invention is applied, cosmetics may be applied in various ways.

In step S330, the cosmetic-coated fabric 400 may be contacted (refer to FIG. 5). For example, the contact part 230 performs a process of folding the fabric 400 in half based on the center line of the fabric 400 in the longitudinal direction, so that one surface of the fabric 400 coated with the cosmetic is mutually exclusive. It can be implemented to overlap. In this way, a partial region of the original fabric 400 overlaps to form a contacted fabric 500, and the upper and lower fabrics of the contacted fabric 500 are the left face part 110 of the three-dimensional mask pack 100 or The right face part 120 may be configured.

In step S340 , one region of the bonded fabric 500 may be fused to form the joint 130 of the three-dimensional mask pack 100 (see FIG. 5 ). Step S340 is for connecting the left face part 110 and the right face part 120 of the three-dimensional mask pack 100, and by forming the joint part 130, the left face part 110 and the right face part 120 are completely It can be unfolded according to the shape of the user's face without being separated.

For example, the fusion unit 240 fuses the fusion region 510 of the bonded fabric 500, and couples at least a portion of the upper and lower fabrics of the bonded fabric 500 to each other, so that the joint 130 ) can be formed. The welding in step S340 may be performed by ultrasonic welding.

According to an embodiment, by ultrasonic welding for the fusion region 510 , the joint 130 may be separated from the fabric 500 to which the fusion is performed while the fusion is performed. In this case, in the process of cutting the contacted fabric 500 into the shape of the three-dimensional mask pack 100 (step S350 ), the region corresponding to the separating part 140 and the cut-out part 150 of the three-dimensional mask pack 100 . It may be implemented to perform the cutting process only for . Through this, it is possible to improve the efficiency of the manufacturing process by simultaneously performing the cutting process of the joint 130 through ultrasonic welding and not performing an additional cutting process on the already separated joint 130 .

Meanwhile, the method of forming the joint 130 in step S340 is not limited to ultrasonic welding, and may be performed in various ways according to an embodiment to which the present invention is applied. For example, the joint 130 is formed by applying an adhesive material to the inner surface of the bonded fabric 500 to adhere the region corresponding to the joint 130 of the upper fabric and the lower fabric, or a heating/pressurizing member The joint 130 may be formed through external heat bonding in which heat is applied from the outside.

In step S350 , the attached fabric 500 may be cut to correspond to the shape of the three-dimensional mask pack 100 (see FIG. 6 ). For example, the cut part 250 is the left face part 110 of the three-dimensional mask pack 100 using the contacted fabric 500 in a state in which the contacted fabric 500 is joined through the step S340 and the joint 130 is formed. ) or it can be cut according to the shape of the right face part 120 .

In step S350 , the cutout 150 formed in the inner region of the three-dimensional mask pack 100 and the joint 130 and the separator 140 constituting the edge region of the three-dimensional mask pack 100 are simultaneously or sequentially formed. This may be performed by cutting, and accordingly, the three-dimensional mask pack 100 of the form shown in (a) of FIG. 1A may be separated from the attached fabric 500 . Through this, the three-dimensional mask pack 100 can be manufactured in which the left face part 110 and the right face part 120 are connected by the joint part 130 and a part is separated by the separating part 140 , and the three-dimensional mask The cutout 150 may be symmetrically formed in the left face part 110 and the right face part 120 of the pack 100 .

In particular, the eye cutout 152 , the mouth cutout 156 , and the ear cutout 158 among the cutouts 150 of the three-dimensional mask pack 100 are formed so that a predetermined area of the attached fabric 500 is opened. It may be cut, and the nose incision 154 may be cut to form an incision line.

According to an embodiment, step S350 may include a primary cutting step and a secondary cutting step. For example, in the first cutting step, a region corresponding to the cutout 150 of the three-dimensional mask pack 100 among the bonded fabric 500 may be cut, and in the second cutting step, the seam 130 and a region corresponding to the separation unit 140 may be cut. Through this, the cutout 150 is first cut in a state in which the edge region of the three-dimensional mask pack 100 is fixed to the attached fabric 500 , and then the joint 130 and the separator 140 are cut by cutting , the cutting process may be implemented to be performed more precisely.

FIG. 7 shows an embodiment of step S340 of the method of FIG. 3 , and FIG. 8 shows a part of a manufacturing process according to the method of FIG. 7 .

First, referring to FIG. 7 , step S340 includes disposing the fabric 500 bonded on the fusion plate 610 ( S342 ); pressing the fusion region 510 of the fabric 500 contacted with the contact blade 630 protruding in a predetermined shape downward (S344); And in a pressurized state, by generating heat resistance from the fusion plate 610 to the fusion region 510, it may include a step (S346) of fusing the fusion region 510. Here, the fusion region 510 is a region corresponding to the joint 130 of the three-dimensional mask pack 100 , and the fusion region 510 may be implemented in a shape corresponding to the shape of the joint 130 .

Referring to FIG. 8 , in step S342 , the bonded fabric 500 may be disposed on the fusion plate 610 . The fusion plate 610 is for generating ultrasonic waves, and the fabric 500 bonded on the fusion plate 610 is disposed, but the bonding portion of the bonded fabric 500 (ie, the fusion region 510) is the fusion plate. It may be positioned on the ultrasonic generator 620 of the 610 .

Subsequently, in step S344, the contacted fabric 500 may be pressed downward with the contact blade 630 . The contact blade 630 has a structure protruding to correspond to the ultrasonic generator 620 of the fusion plate 610 and the fusion region 510 of the bonded fabric 500 , and has a shape corresponding to the joint 130 . can be configured. As the contact blade 630 moves downward toward the contacted fabric 500 , the fusion region 510 of the upper and lower fabrics of the contacted fabric 500 may be pressed downward.

On the other hand, the above description of the shape of the contact blade 630 is exemplary, and according to the embodiment, in a state where a part of the fusion region 510 of the fabric 500 contacted by the contact blade 630 is pressed, As the contact blade 630 moves along the fusion region 510 and fusion is performed, the joint 130 may be formed.

In step S346, in a state in which the fusion region 510 is pressed down by step S344, the fusion region 510 of the bonded fabric 500 may be fused. In step S346, the ultrasonic wave generated from the fusion plate 610 (in particular, the ultrasonic wave generating unit 620 of the fusion plate 610) is heat-resistant in the fusion region 510 of the upper end and the lower end of the fabric 500 to which it is bonded. This can be done by generating

More specifically, in the fusion region 510 of the upper and lower fabrics of the bonded fabric 500, vibration is generated by ultrasonic waves, heat resistance is generated therefrom, and the upper fabric and the lower fabric are fused in the fusion region 510. By heat-sealing to each other, the joint 130 of the three-dimensional mask pack 100 may be formed.

According to an embodiment, the ultrasonic welding may be repeatedly performed at least once or more. In this case, when ultrasonic welding is performed a plurality of times, the welding region of the bonded fabric 500 may be different. For example, when ultrasonic welding is performed twice, in the case of the first ultrasonic welding, the welding is performed on some of the welding regions 510 of the bonded fabric 500, and in the second ultrasonic welding, , it may be implemented such that fusion is performed on an area that is not fused through primary ultrasonic welding. Through this, by making the joint 130 more firmly bonded, it is possible to prevent the joint 130 from opening up and prevent the applied cosmetic from leaking through the joint 130 .

As described above, an optimal embodiment has been disclosed in the drawings and the specification. Although specific terms are used herein, they are used only for the purpose of describing the present invention, and are not used to limit the meaning or scope of the present invention described in the claims. Therefore, it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom.
