Description

Apparatus and method for continuous production of moisture film {APPARATUS AND METHOD FOR CONTINUOUSLY MANUFACTURING MOISTURE FILM}

The present invention relates to an apparatus and a method for continuously producing a moisture film, and in particular to at least one loading surface formed by at least one belt conveyor and used to support the underlying fabric layer, so as to continuously produce the film. An apparatus and method for continuously producing a moisture film comprising a. The lower fabric layer is moved in synchronization with the loading surface and the first fixing solution layer, the gel layer, and the second fixing solution layer are coated in sequence. Therefore, the film is slowly formed on the lower fabric layer, and the continuous production of the moisture film with or without the carrier is completed.

Film forming materials of the present invention include, but are not limited to, salt compounds of alginic acid and alginic acid (alginate). Alginic acid (referred to herein as gel) is a natural polymer that is likely to react with salt compounds (such as, but not limited to, the first and second fixation solutions herein) to form an alginic acid film (film in the present invention). For example, water soluble sodium alginate (gel) reacts with divalent calcium ions in a salt compound solution (fixing solution). Therefore, crosslinking and curing reaction occurs to form an insoluble calcium alginate film. During the manufacturing process, the film is made of (but not limited to) long continuous / discontinuous strips with a constant width and processed by the following treatment, which involves cutting the mask into the required shape by a cutting die. The mask is applied to a cosmetic moisture mask. The film referred to in the present invention is used as a face mask so that the film can be referred to as a mask. In the present invention, a film having a large area is first produced, and then the film is cut into a plurality of masks having a certain shape by a cutting die.

However, most of these prior arts focus on the wt% of each component in the film composition or film. Yet, there is no technical solution to the problem of how moisture films are mass produced and how the cost is reduced.

Moreover, the moisture film (mask) is divided into two forms with no carrier or with carrier during use. Moisture films without carriers only include films of constant thickness, such as alginate masks, but moisture films with carriers consist of a film of constant thickness and a thin layer of carrier, such as a nonwoven fabric, interconnected with one another. In general, a thin layer of carrier is incorporated in and incorporated into the film such that the film and carrier cannot be separated or difficult.

With respect to the package pattern of the moisture film (mask), the moisture film with or without a carrier is folded or stored directly, but the physiological saline to maintain a specific solution (film moisture or essence / serum for face care) Such as, but not limited to. During use, the consumer opens the sealed bag and removes the moisture film. Moisture films with or without carriers are soft, thin membranes. For ease of movement and ease of use during manufacture / packaging, it is attached to at least one surface of a protective film or a moisture film with or without a carrier at the end of the preparation. For example, a piece of pearl paper is attached to one surface of the moisture film to support during packaging or storage, while the other surface of the moisture film allows the solution in the sealing bag to pass through into the film. The nonwoven layer is attached. In the present invention, the attached protective film is different from the thin layer of the carrier in the moisture film having the carrier.

In addition, devices or methods for the continuous production of moisture films now available have the following disadvantages:

First, the moisture film is a soft, thin gel membrane. Therefore, the preparation and cutting of the membrane is not so easy. For ease of manufacture or cutting into the required shape, we propose the idea that a flat loading surface or bottom fabric layer is used to carry the moisture film. And the entire film forming process was completed during the transfer.

With reference to EP2111926A1 (PCT / JP2008 / 050822, WO2008 / 0090892), moisture films with or without carriers cannot be produced continuously and quickly at the end of the production. The production of a moisture film is a process for coating gels (alginic acid) and related devices (or work stations), fixation solutions (such as salt compounds) and related devices (or work stations), devices which cause crosslinking reactions between the gels and fixation solutions (Or a work station), and / or a coating process of the device (or work station) for stopping the crosslinking reaction between the fixation solution and the gel, a process for curing and forming a soft moisture film. However, the arrangement of such devices is not efficient. For example, the impregnation coater and gravure coater are two main work stations, separated from one another. The continuous support material then passes through the two work stations by the rotation or traction effect of multiple idler wheels or rotating wheels to coat the salt compound (fixing solution) and alginic acid (gel) on the surface of the continuous support material. . There is no continuous conveyor used to load support material in the entire manufacturing apparatus. Therefore, each film-forming material, such as alginic acid (gel) or salt compound (fixing solution), cannot be coated continuously and quickly to form a film. In addition, many conveyors (such as idler wheels or rotating wheels) are required to connect a separate work station at the end of manufacturing so that the production of the moisture film can be performed and completed (as shown in FIGS. 2-4 of EP2111926A1). together). Therefore, the whole apparatus and manufacturing process are more complicated and occupy a large space. This increases device and manufacturing costs. And manufacturing is not a continuous and rapid process.

The third is that the moisture film is divided into two forms with or without a carrier. In the prior art, at the end of manufacturing the same apparatus cannot be used to produce both types of moisture film by simple replacement or modification of the device or work station in the apparatus. In general, new devices are designed and used to produce new types of moisture films. This causes waste and increases the cost and space for new equipment. Competitiveness is greatly affected.

There is room for improvement, and to overcome the above disadvantages, there is a need to provide improvements and new designs of devices and there is a need to provide new designs of devices and methods for producing moisture films.

It is therefore a primary object of the present invention to provide an apparatus for the continuous production of a moisture film, which is planar upward and comprises at least one circular loading surface formed by a belt conveyor. The belt conveyor is moved from the input end (front end) to the output end (rear end) along the conveying direction. The lower fabric layer with moisture absorbency is arranged on the loading surface and moved backwards in synchronization with the loading surface to accommodate various film forming materials such as solutions and gels for film formation. The following devices are arranged on the loading surface in turn from the input end to the output end. The first fixation solution coating device is used to coat the first fixation solution layer on the lower fabric layer. The gel coating device is then used to coat the gel layer over the first fixation solution layer to effect crosslinking and curing reaction in the upward direction. The second fixation solution coating device is for coating the second fixation solution layer on the gel layer and performing crosslinking and curing reaction in the downward direction. Thereby, a film having a certain thickness is gradually formed at the upper surface of the lower fabric layer during the synchronous movement of the loading surface and the lower fabric layer, and the continuous production of the moisture film having no carrier is completed. Therefore, both mass production and cost reduction are achieved.

It is another object of the present invention to provide an apparatus for continuously producing a moisture film, further comprising an upper fabric input device disposed between the second fixation solution coating device and the gel coating device. The upper fabric layer provided by the upper fabric input device correspondingly adheres onto the gel layer. The second fixation solution layer is then coated over the upper fabric layer such that the upper fabric layer is clipped between the second fixation solution layer and the gel layer after crosslinking and curing reaction. Thereby, a film having a predetermined thickness and including the upper fabric layer is gradually formed at the upper surface of the lower fabric layer which is moved in synchronization with the loading surface. And the original continuous production of a moisture film without a carrier is converted to a continuous production process of a moisture film with a carrier. Not only mass production and cost reduction are achieved, but also the shape and convenience of use of the moisture film are improved.

It is another object of the present invention to provide an apparatus for continuously producing a moisture film comprising a crosslinking control region disposed behind a second fixation solution coating device. The moisture film passed through the second fixation solution coating device is washed in the crosslinking control region such that the crosslinking reaction between the fixation solution and the gel in the film is stopped. Therefore, the flexibility of the formed film can be controlled the manufacturing process.

It is another object of the present invention to provide a method of continuously producing a moisture film comprising the following steps. Step 1: Provide at least one circular loading surface used as a working platform for film formation. The loading surface is a plane facing upward and is moved circularly along the conveying direction from the input end to the output end. Step 2: in turn provides a lower fabric layer having moisture absorbency moved in synchronization with the loading surface to receive various film forming materials and to perform film forming operations. Step 3: Provide a first fix solution coating device for coating the first fix solution layer on the lower fabric layer. Step 4: Coating the gel layer over the first fixation solution layer and provide a gel coating device for having a crosslinking and curing reaction in an upward direction therebetween. Step 5: Provide a second fix solution coating device that is used to coat a second fix solution layer over the gel layer to effect crosslinking and curing reaction in a mostly downward direction. Therefore, a film with a certain thickness is formed slowly at the upper surface of the lower fabric layer which is moved in synchronization with the loading surface. This completes the continuous production of the moisture film having no carrier.

It is a further object of the present invention to provide a method for continuously producing a moisture film comprising the following steps. Step 1: Provide at least one circular loading surface used as a working platform for film formation. The loading surface is planar upward and is moved in a circular direction along the conveying direction from the input end to the output end. Step 2: in turn provides a lower fabric layer having moisture absorbency moved in synchronization with the loading surface to receive various film forming materials and to perform film forming operations. Step 3: Provide a first fix solution coating device used to coat the first fix solution layer on the lower fabric layer. Step 4: Coating the gel layer over the first fixation solution layer and provide a gel coating device for having a crosslinking and curing reaction in an upward direction therebetween. Step 5: provide a top fabric layer that adheres onto the gel layer. Step 6: Provide a second fixation solution coating device that is used to coat a second fixation solution layer over the top fabric layer to effect crosslinking and curing reaction in a mostly downward direction. The upper fabric layer is clipped between the second fixation solution layer and the gel layer. Thereby, the film having a specific thickness and including the upper fabric layer is gradually formed on the upper surface of the lower fabric layer moved in synchronization with the loading surface, and the continuous production of the moisture film with the carrier is completed.

The lower fabric layer is movably disposed on the loading surface of the belt conveyor. The roll of lower fabric layer is disposed in front of the belt conveyor such that the lower fabric layer passes through the input end and is continuously input onto the loading surface. Therefore, the continuous lower fabric layer is moved in synchronism with the loading surface to accommodate various film forming materials for film formation on its surface. The continuous lower fabric layer then still supports and moves the film formed at the next work station for subsequent work.

The lower fabric layer is fixed on the loading surface of the belt conveyor. The lower fabric layer is disposed directly on and moved in synchronization with the loading surface of the belt conveyor to receive various film forming materials for film formation on its surface. Therefore, a long strip of film is formed on the surface of the lower fabric layer on the loading surface of the belt conveyor. After the film forming process is completed, the lower fabric layer is rotated in a circle with the loading surface of the belt conveyor. For long strips of film that have already been formed, it is separated from the lower fabric layer on the loading surface and moved back to one of the subsequent work stations.

The subsequent work area is arranged behind the output end of the circular loading surface of the belt conveyor. By means of at least one circulating working surface which is moved upwards and along the conveying direction and formed by the belt conveyor, the moisture film, which has no carrier or is already prepared, is moved backwards for subsequent processing and enters the subsequent working area. .

Embodiments of the present invention are shown in schematic side view in FIGS. The movement / transfer direction of the apparatus for continuously producing the moisture film of the present invention is directed from left to right from FIGS. 1 to 9. The left side in the figure is defined as the front side, while the right side in the figure is defined as the rear side. The direction perpendicular to the plane of the drawing is defined as the width direction. For convenience of explanation, the lower fabric layer 20, the first fixing solution layer 31, the gel layer 41, the second fixing solution layer 51 and the upper fabric layer 81 of the embodiment are separated from each other in the figure. And parallel lines. In fact, the components 20, 31, 41, 51, 81 are closely connected to each other due to the crosslinking reaction therebetween or closely attached to each other due to spray coating, dip coating or the like. There is no gap (as shown in the figure) between the two adjacent components described above.

Referring to FIG. 1, an apparatus for continuously manufacturing the moisture film of the present invention includes at least one belt conveyor 10 having at least one loading surface 11, and a lower fabric layer 20 having water absorbency. , First fixation solution coating device 30, gel coating device 40, and second fixation solution coating device 50. Three coating devices 30, 40, 50 are arranged on or in front of the loading surface 11 in turn from the input end 12 to the output end 13 along the conveying direction of the loading surface 11. The belt conveyor 10 has various forms, and the loading surface 11 has a different structure according to the shape of the belt conveyor 10. The loading surface 11 may be a continuous surface such as, for example, a PVC belt conveyor, a PU belt conveyor, a Teflon belt conveyor, a leather belt conveyor, or the like, or a discontinuous surface such as a rolling conveyor, a chain conveyor, or the like, shown by a thick dotted line. At least one belt conveyor 10 with at least one loading surface 11 means a different combination of belt conveyors 10 with a loading surface 11, which is limited to the conveying manner of the belt conveyor 10. There is no The apparatus may comprise a plurality of belt conveyors 10 each having a corresponding loading surface 11. Alternatively, multiple belt conveyors 10 are connected to form a single stacking surface 11. Alternatively, the surface of the single belt conveyor 10 is divided into a number of segments, each forming a loading surface 11.

The belt conveyor 10 with at least one loading surface 11 is used as a platform for film formation and a working surface for the continuous formation of a moisture film. The circulation loading surface 11 is an upward flat surface and moves in a circular direction from the input end 12 to the output end 13 in a circular direction. The belt conveyor 10 is designed to have a certain length and a certain width. The loading surface 11 also has a certain length and a width so as to form a working surface for forming the moisture film. In addition, the lower fabric layer 20 having moisture absorbency is arranged to be movable on the mounting surface 11, or is fixed to the mounting surface 11 (as shown in FIGS. 1 to 4) or (as shown in FIG. 5). As shown). Therefore, the lower fabric layer 20 is moved in synchronization with the loading surface 11. During synchronous movement, the lower fabric layer 20 is loaded with various film forming materials such as fixation solutions 31, 51, sodium compounds and gels 41 (alginic acid), as shown in FIG. Then, a film having a certain thickness is formed slowly and continuously on the upper surface of the lower fabric layer 20. This means that film formation is performed on the lower fabric layer 20.

As shown in FIG. 1, the lower fabric layer 20 is designed as, but not limited to, a continuous long strip of fabric. Source 21 is a roll of lower fabric layer 20. The lower fabric layer 20 is provided continuously by the source 21 and smoothly passes through the input end 12 attached to the circulation loading surface 11. In FIG. 1, the lower fabric layer 20 and the loading surface 11 are represented by two separate lines. Then, the lower fabric layer 20 moves in synchronization with the loading surface 11 and leaves the loading surface 11 through the output end 12 to be output toward the rear side of the loading surface 11. After output, the continuous lower fabric layer 20 is transferred into work equipment 70 for other predetermined subsequent work, such as automatic or manual film cutting device 71. For example, another belt conveyor 72 is also used with the film cutting device 71. Thereby, a cutting station is formed and used with the continuous lower fabric layer 20 to cut the continuous moisture film into multiple pieces of film. The film is then processed by another work station, such as a smoothing work station or a packaging work station. Subsequent work equipment 70 includes other work stations or other devices depending on various requirements for subsequent work.

The first fixation solution coating device 30 is used to coat the first fixation solution layer 31 on the lower fabric layer 20 moving with the loading surface 11. In an embodiment of the invention, the first fixation solution coating device 30 is arranged above the loading surface 11. As shown in another embodiment of FIG. 4, the first fixation solution coating device 30 may also be arranged in front of the loading surface 11. According to the shape or structure of the moisture film, the first fixing solution layer 31 is uniformly spread over the lower fabric layer 20, but is not limited thereto. For example, when the moisture film has a special structure or shape, such as a half face mask that covers only the top half or bottom half of the user's face, the present invention performs the coating process in a non-uniform manner. For example, only certain areas on the lower fabric layer 20 are coated. Moreover, the coating method of the present invention is not limited as long as the first fixing solution layer 31 can be formed on the lower fabric layer 20. The method of coating may be spray coating, dip coating or a combination thereof. In FIG. 1, the first fixation solution coating device 30 is coated by spray coating.

As shown in FIG. 1, the gel coating device 40 is arranged at the rear side of the first fixation solution coating device 30. After the first fixation solution layer 31 is coated on the lower fabric layer 20 and moved with the loading surface 11 to the working range of the gel coating device 40, the gel layer 41 having a predetermined thickness is formed into a gel. It is coated on the first layer of fixation solution 31 by the coating device 40. Then, together with the loading surface 11, the gel layer 41, the first fixing solution layer 31, and the lower fabric layer 20 continuously move backwards. During the migration, the first fixation solution layer 31 and the gel layer 41 are crosslinked and cured to slowly form a film.

In this embodiment, the first fixation solution layer 31 is coated over the lower fabric layer 20, and then the gel layer 41 is coated over the first fixation solution layer 31. Therefore, the first fixation solution layer 31 may first contact the lower fabric layer 20 and penetrate into the interior through the upper (or upper and bottom) surfaces of the lower fabric layer 20. When the upper surface (containing divalent metal ions) of the first fixing solution layer 31 is in contact with the gel layer 41, the crosslinking and curing reaction starts immediately. Therefore, a thin layer of film is formed therebetween. The thin layer of film acts like a shielding surface to prevent the gel layer 41 from filtering inside through the top (or bottom) of the lower fabric layer 20. This reacts with the gel layer 41 (from bottom to top) so that the first fixation solution layer 31 on the surface of the lower fabric layer 20 has a crosslinking reaction therebetween and the top of the lower fabric layer 20 It means stopping the penetration (from top to bottom) into the lower fabric layer 20 through cotton. Therefore, a moisture film made of a hydrogel composite having a network structure is formed on the upper surface of the lower fabric layer 20. The formed moisture films 31 and 41 are likely to be separated from the lower fabric layer 20 during use. Therefore, the moisture film of the present invention is considered to have no carrier.

Referring to FIG. 1, a second fixation solution coating device 50 is installed on the back side of the gel coating device 40. After the gel layer 41 is coated on the first fixation solution layer 31 and moved rearward along the lower fabric layer 20 along the loading surface 11 into the working range of the second fixation solution coating device 50. The second fixation solution layer 51 is coated over the gel layer 41 by a second fixation solution coating device 50. The second fixation solution layer 51, the gel layer 41, the first fixation solution layer 31 and the lower fabric layer 20 are attached to one another (integrated into one part) and the second fixation solution layer 51 ) Is coated on the gel layer 41 and then moved rearward in synchronization with the loading surface. During this movement, the coated second fixation solution layer 51 initiates crosslinking in the downward direction to form a film and reacts with the gel layer 41 to slowly cure. By the crosslinking of the first fixing solution layer 31 with the gel layer 41 and the crosslinking of the gel layer 41 and the second fixing solution layer 51, the films 100 and 31 having a constant thickness are provided. 41 and 51 are formed on the lower fabric layer 20 which is moved in synchronization with the loading surface 11 which is conveyed backward. Therefore, the curing period of the film 100 formed on the gel layer 41 is reduced. That is, the cured film 100 (31, 41, 51) is formed by the crosslinking of the gel layer 41 and the first and second fixing solution layers 31, 51. Therefore, the cured film 100 is represented by reference numerals 31, 41, 51 in the figures. Films 100, 31, 41, and 51 are also produced continuously on the lower fabric layer 20, which is moved backwards in synchronization with the loading surface 11. Therefore, the film 100, 31, 41, 51 is adhered closely to the lower fabric layer 20 to form a long continuous strip 101 (20, 31, 41, 51), and the loading surface 11. It is moved in synchronism with the loading surface 11 to be output through the output end 12 of the. After leaving the loading surface 11, the long continuous strips 101 (20, 31, 41, 51) are processed by subsequent work. While leaving the loading surface 11, the film 100, 31, 41, 51 adheres closely to the underlying fabric layer 20 to form a long continuous strip 101 (20, 31, 41, 51). do. Therefore, long continuous strips 101 in the figures are indicated by reference numerals 20, 31, 41, 51. During use, the film 100, 31, 41, 51 is easily separated from the lower fabric layer 20. Therefore, the continuous production of the moisture film having no carrier is completed. The moisture film 100 (31, 41, 51) having no carrier is produced quickly and continuously. Thus, mass production and cost reduction are achieved.

In addition, the main material of the first fixing solution layer 31 or the second fixing solution layer 51 includes a fixing solution required for forming a film such as a salt compound. Indeed, the material for the first fixation solution layer 31 or the second fixation solution layer 51 may also contain other specific ingredients, such as essences or serums, which are essentially necessary for certain functions of the mask, such as whitening, anti-wrinkle treatments, and the like. Can be.

With reference to FIG. 2, another embodiment is shown. The difference between this embodiment and the above embodiment is that an upper fabric input device 80 for providing the upper fabric layer 81 is disposed between the gel coating device 40 and the second fixation solution coating device 50. In the figure, the upper fabric layer 81 is first flat relative to the gel layer 41. The second fixation solution layer 51 is coated over the upper fabric layer 81 at the same time or later. The upper fabric layer 81 first contacts the gel layer 41 such that the gel layer 41 penetrates through the bottom surface of the upper fabric layer 81 into the inner layer of the upper fabric layer 81. Therefore, when the second fixation solution layer 51 is coated on the upper fabric layer 81 in which the gel layer 41 has penetrated, the second fixation solution layer 51 is already the inner layer of the upper fabric layer 81. It can penetrate into the inner layer of the upper fabric layer 81 through the top surface of the upper fabric layer 81 to react with the gel layer 41 penetrated therein and form a crosslinking reaction therebetween. The upper fabric by crosslinking in an upward direction between the first fixation solution layer 31 and the gel layer 41 and crosslinking in a downward direction between the second fixation solution layer 51 and the gel layer 41. Layer 81 is clipped or received between second solution layer 51 and gel layer 41. Thereby, during the rearward movement of loading surface 11 and lower fabric layer 20, films 110 (31, 41, 81, 51) with a constant thickness and upper fabric layer 81 are shown in FIG. 2. It is formed slowly in the upper surface of the lower fabric layer 20 as shown. Therefore, the continuous production of the moisture film with the carrier is completed.

In the second embodiment, the upper fabric layer 81 provided by the upper fabric input device 80 is, but is not limited to, a long continuous strip of fabric. The long continuous strip of top fabric layer 81 in FIG. 2 serves as a source 82 for continuous supply of the top fabric layer 81 and for smooth attachment of the top fabric layer 81 to the gel layer 41. It is wound up on the roll used. Moreover, the use of mechanical elements such as the idle gear 83 or a combination thereof such as an idle gear set can improve the convenience or precision of operation in the operation of the upper fabric input device 80. Therefore, the upper fabric layer 81 can be a plane that is easily and accurately attached to the gel layer 41.

In addition, there is no limitation in the order of the time when the second fixing solution layer 51 is coated on the upper fabric layer 81 and the time when the upper fabric layer 81 is attached to the gel layer 41 and planarized. As shown in FIG. 2, the upper fabric layer 81 is correspondingly attached to the gel layer 41 and flattened, and then the second fixing solution layer 51 is sprayed in the downward direction to the upper fabric layer. Over 81. Alternatively, both procedures are performed simultaneously. Therefore, the continuous production of the moisture film with the carrier is completed. Referring to FIG. 3, the second fixing solution layer 51 is coated on the upper fabric layer 81 by immersion coating. Then, the upper fabric layer 81 coated with the second fixing solution layer 51 responds smoothly to the gel layer 41. Due to the second fixing solution layer 51 present between the upper fabric layer 81 and the gel layer 41, the upper fabric layer 81 of FIG. 3 is formed with the film 110 (31, 41, 81, 51). Can be easily separated from. Therefore, a continuous production of a moisture film having no carrier as shown in FIG. 3 appears.

In FIG. 2, the film 110 is not only by crosslinking in the upward direction between the first fixation solution layer 31 and the gel layer 41, but also through the upper fabric layer 81, the second fixation solution layer 51. ) And the gel layer 41 by crosslinking in the downward direction. Therefore, the upper fabric layer 81 in the formed film 110 (31, 41, 81, 51) cannot be easily separated from the film 110 (31, 41, 81, 51). Comparing the first embodiment in FIG. 1 and the second embodiment in FIG. 2, the film 110 (31, 41, 81, 51) of the second embodiment comprising an upper fabric layer 81 integrated therewith. Is continuously formed on the lower fabric layer 20 which is moved rearward in synchronization with the loading surface 11. Indeed, the films 110, 31, 41, 81, 51 and the lower fabric layer 20 are glued to form long, continuous strips 111, 20, 31, 41, 81, 51. As shown in FIG. 2, the long continuous strips 111 (20, 31, 41, 81, 51) are synchronized with the loading surface 11 to be output through the output end 12 of the loading surface 11. Is moved. After leaving loading surface (11). Long continuous strips 111 (20, 31, 41, 81, 51) are processed by subsequent work. During subsequent operations, the film 110 (31, 41, 81, 51) and the lower fabric layer 20 are still bonded to each other to form a long continuous strip 111 (20, 31, 41, 81, 51). . During use, the films 110, 31, 41, 81, 51 can be easily separated from the lower fabric layer 20 after being cut into various shapes of masks ready to use.
