Description

Continuous film forming manufacturing equipment for wet film and film forming method thereof

The present invention relates to a manufacturing apparatus for a wet film and a film forming method thereof, and more particularly to a carrier surface for forming at least one continuous film forming by using at least one circulating conveyor belt, and a bearing surface is provided on the bearing surface The material layer of the carrier layer synchronously transporting and moving under the moving layer for sequentially carrying or coating each film forming layer comprises a first fixing liquid layer, a colloid layer and a second fixing liquid layer, so that the lower layer is In the process of synchronous conveying movement of the bearing surface, a film of appropriate thickness can be gradually formed on the upper surface thereof, thereby simply completing a continuous film forming process of a carrier-free or carrier-free wet mask.

The film-forming material referred to in the present invention comprises alginic acid and an alginate compound, but is not intended to limit the present invention, wherein the alginic acid (that is, the colloid in the present invention, but not intended to limit the invention) is a natural one. The polymer can form various alginate films with metal ions in the salt compound (that is, the first and second fixing liquids referred to in the present invention but not limiting the present invention) ( That is, the film referred to in the present invention is not intended to limit the present invention), for example, water-soluble sodium alginate (colloid) can be cross-linked with divalent calcium ions in a salt compound (fixed solution). Curing action to form a water-insoluble calcium alginate film (film). If the film is made into a continuous or discontinuous strip film of appropriate width during the process (but not to limit the invention), the subsequent process may include The mask cutting operation, for example, cutting the mask of the designed shape by using a knife mold on the long strip film, and supplying it to the field of wet mask for cosmetic use. Since the film referred to in the present invention is mostly designed for a mask which is commonly used on the face of the market, the film referred to in the present invention may also be referred to as a mask. For the purpose of the present invention, a large-area film type is first formed, and a fixed-shape mask is cut on the film by a cutting method (for example, using a die but not limited). To limit the invention.

At present, there are some first in the related technical field of wet film (mask). The prior art is, for example, US 6,080,420, US 6,258,995, US 6,203,845, US 6,201,164, US 6,372,248, US 6,326,524, US 5,144,016, US 5,230,853, US 5,622,666, US 5,660,857, US 5,675,957, US 5,144,016, US 2005/0287193, US 2010/0227164; GB 9419572, GB 9501514, GB 9516930, PCT/GB 9502284 (WO96/10106), PCT/GB 9601719 (WO97/03710), PCT/GB 9701098 (WO97/39781), PCT/DK 9700292 (publication number WO98/02196) WO2008/072817, WO03092754, EP2111926A1 (WO2008/0090892, PCT/JP2008/050822); JP2010-189386, WO99/20378A1, and the like. However, the above-mentioned prior art claims or technical features are mostly focused on the composition of the wet film or the weight percentage (wt%) relationship between the components, and actually do not achieve mass production for the wet film. Or reduce production costs and other issues to propose effective technical solutions.

In addition, according to the use form of the wet film (mask), the conventional wet glue The membrane can be divided into two types: no carrier and carrier; the carrier-free wet film means that only a suitable thickness of the film (such as alginate mask) is used; and the carrier wet film refers to In use, a film of a suitable thickness is combined with a thin layer of carrier such as a nonwoven fabric, wherein the layer carrier It is generally contained in the film to be integrated into one body and cannot be separated or separated.

According to the common packaging mode of the wet film (mask), there is no carrier and Most of the carrier wet film is stored directly or folded and stored in a sealed bag containing a specific liquid (such as salt water for moisturizing or containing essence to enhance cosmetic function), but not limited to consumers. When it is used, the package is unpacked to take out the wet film; since the carrier-free or carrier-containing wet film is a soft and thin film structure, it is convenient for production (such as transport movement in the process) or packaging ( If it is folded and then stored in a sealed package) or so that consumers can easily take it out and use it in a sealed package (such as unfolding the film and attach it to the face), the manufacturing end is often without carrier or carrier wet. Applying a protective film to at least one side of the film, for example, attaching a pearl paper on one side (but not limited to) to support the wet film (mask) to facilitate packaging or folding storage, or The other side is then covered with a non-woven layer (but not limited) for allowing the liquid in the sealed package to penetrate the nonwoven layer to be immersed in the film for moisturization. In the embodiment of the present invention, the above-mentioned additionally coated protective film is not regarded as a thin layer carrier as the carrier wet mask in the present invention.

Further, in the technical field of a film forming manufacturing apparatus or a film forming method relating to a wet type film, there are currently the following disadvantages:

First, the wet film is a soft and thin gel film. For the convenience of process or cutting (such as cutting the shape of the mask), the inventor first discovered and believed that the wet film could The use of a flat bearing surface or a layer of cloth for transport and the completion of the entire film forming process at the same time is the most advantageous for the manufacture of wet film, but the prior art does not reveal such a concept. It is difficult to increase the wet film process, which is not conducive to the development of wet film (mask).

Second, in terms of conventional film-forming processes and related manufacturing equipment, such as EU patents EP 2111926 A1 (international application number: PCT/JP2008/050822, international publication number: ISBN 2008/0090892), the manufacturing end cannot continuously and quickly produce a carrier-free or carrier-free wet film. The film forming process of the wet film comprises at least: a coating operation of a colloid (such as alginic acid) and a device (or a workstation); a coating operation of a fixing liquid (such as a salt compound) and a device (or a workstation) thereof; And a device (or workstation) for crosslinking the above two film-forming material colloids and fixatives to a predetermined extent and/or capable of stopping the cross-linking stop device (or workstation) to shape and form a suitable softness Wet film; however, the conventional manufacturing equipment lacks an efficient layout in the film forming process. For example, the manufacturing equipment disclosed in EP 2111926 A1 is mainly provided with an impregnation coater and a gravure printing machine. Coater) The two main workstations, which utilize the steering and/or traction of a plurality of wheels or wheels to enable a continuous support substrate to pass through the two main working areas in succession for the continuous support bottom. The coating operation of the salt compound (that is, the fixing liquid referred to in the present invention) and alginic acid (referred to as the colloid in the present invention) is carried out on the surface of the material, so that the entire manufacturing equipment and the film forming process are lacking one. a continuous conveyor belt carrying the support substrate, so that each film-forming material such as alginic acid (colloid) or a salt compound (fixed liquid) cannot be continuously and rapidly carried out by the support substrate and is finished wet. The film forming process of the mask; that is, the manufacturing end often needs to be provided with a plurality of separate workstations (such as the separate setting of the impregnation coater and the gravure coater gravure coater shown in Figure 2-4 of EP2111926A1) And a plurality of additional conveying devices (such as a plurality of wheels or runners) for connecting and transporting between separate independent workstations, and capable of performing and completing the film forming process of the wet film, resulting in an overall manufacturing equipment and a manufacturing process thereof. Complex (as shown in Figure 2-4 of EP2111926A1), which accounts for a large volume, relatively increases equipment and manufacturing costs, but fails to achieve continuous and rapid completion and completion of the film forming process. effect.

Third, the wet film mainly contains two kinds of carriers and carriers, but it is known. In terms of technology, the manufacturing end cannot use the basic device of the same set of manufacturing equipment, so that it can choose to manufacture any kind of wet film (mask) without carrier and carrier by simple replacement or addition, that is, if the manufacturing end is original The use of a set of manufacturing equipment to specialize in the manufacture of unsupported wet film, when the consumer or client needs to change from the carrierless wet film to the carrier wet film, the manufacturing end can not use the same set The basic device for manufacturing equipment is simply replaced or added for the manufacture of a carrier-coated wet film; in general, the manufacturing end is additionally designed with a new set of manufacturing equipment to manufacture the carrier-containing wet glue. Membrane, which causes a waste of manufacturing equipment and an increase in manufacturing cost, and increases the use space, is not conducive to the competition of the film (mask) industry.

In fact, the research by the inventor of the case found that a set is used to manufacture either In the case of a carrier or a carrier-free wet film manufacturing apparatus, various basic devices (or workstations) for forming a main film of the wet film (for example, alginate film), for example, One of the first fixed liquid coating device, one colloid coating device and one second fixed liquid coating device disclosed in the present disclosure (described later), if the operation function of each workstation and its arrangement in the production process are arranged In general, it can be regarded as the same or similar, that is, the work functions of the workstations are common; however, the prior art, such as EP 2111926 A1, is often only designed to manufacture a single wet mask, such as a carrier or a carrier. In one case, when the manufacturing end is to manufacture two kinds of wet masks without carrier and carrier, two sets of different manufacturing equipments must be provided to manufacture separately, so the conventional technology does not consider the commonality of the working functions of the workstations. Therefore, the arrangement of the workstations in the overall manufacturing equipment and the manufacturing process thereof are complicated (as shown in Figure 2-4 of EP2111926A1). Larger, and the manufacturing side can not Using the same set of manufacturing equipment, it can be easily replaced or added, so that the manufacturing end can choose to manufacture two kinds of wet masks without carrier and carrier, which increases the equipment and manufacturing cost, but still cannot achieve continuous and rapid progress. Complete the effect of the film forming process.

It is known from the above that it has a sea alginate film and contains no carrier or carrier.

The type of the circulating conveyor belt 10 is not limited, and the bearing surface 11 can have different structures depending on the type of the circulating conveyor belt 10, such as a continuous surface structure such as a PVC conveyor belt, a PU conveyor belt, and a fluorocarbon. Conveyor belts, belt conveyor belts, etc., may also be non-continuous surface structures such as roller conveyor belts, chain conveyor belts, etc., which are referred to herein as bearing surfaces 11, and are indicated by thick broken lines in the drawings. Moreover, the at least one circulating conveyor belt 10 has at least one bearing surface 11 , which means that the conveying manner of the circulating conveyor belt 10 is not limited, and the plurality of circulating conveyor belts 10 can be used to form an equal number of multiple carriers. The face 11, or a plurality of endless conveyor belts 10, are connected to form a single bearing surface 11, or a plurality of sections of the bearing surface 11 are separated by a circulating conveyor belt 10.

The present invention utilizes the at least one circulating conveyor belt 10 to form at least one cycle The bearing surface 11 is provided as a film forming work platform, that is, as a working surface for continuously forming a wet film. The circulating bearing surface 11 has an upwardly facing flat surface and is cyclically moved from the input end 12 to the output end 13 in the conveying direction. The endless conveyor belt 10 is designed to have an appropriate length (longitudinal length in the conveying direction) and a width (horizontal direction perpendicular to the conveying direction), so the circulating bearing The carrier surface 11 is also provided with a suitable length and width for use as a working surface for forming the wet film. Moreover, the surface of the bearing surface 11 is moved in a movable manner (as shown in FIGS. 1 to 4) or in a fixed manner (as illustrated in FIG. 5), and the carrier can be synchronously transported along with the bearing surface 13.

The conveying movement is synchronously carried out, and finally the output end 12 of the bearing surface 11 is output backwards away from the bearing surface 11. The continuous lower fabric layer 20 can be transported to other pre-arranged subsequent work equipment 70 for other subsequent operations, such as an automated or manual cutting mask device 71 and in conjunction with another endless conveyor belt 72. By way of example and not limitation, a cutting station can be constructed for cutting a wet film that has been formed on the continuous lower layer 20 to be divided into a single mask, or a workstation having other functions such as a finishing station or The packaging workstations and the like; since the subsequent working device 70 can make different functions of the device or the workstation to perform different subsequent operations, which is not the focus of the present invention, it will not be repeated here.

The first fixed liquid coating device 30 is configured to be synchronously conveyed along the bearing surface 11 A first fixing liquid layer 31 is coated on the moving cloth layer 20. In the first embodiment, the first fixed liquid coating device 30 is disposed above the bearing surface 11 but is not used to limit the present invention. For example, the first fixed liquid coating device 30 may also be disposed on the bearing. The front side of the face 11 is as shown in Fig. 4 (to be described later). Further, depending on the general shape of the general wet mask (such as the shape of the face) or the configuration, the first fixed liquid layer 31 is uniformly coated on the lower layer 20 without limitation, for example, when the wet mask has a special When constructing or special shapes, such as designing a half-face mask (for covering only the upper half or the lower half of the face), the present invention can perform a coating operation in a non-uniform manner, such as only on the lower layer 20 Coating work is performed in a specific area. The coating operation of the present invention is mainly to enable the first fixing liquid layer 31 to be formed on the lower cloth layer 20, but the working mode adopted by the coating operation is not limited, and the spraying method and the immersion method may be included. But not limited. In other words, the coating method described in the present invention may include any one of a spraying method and an immersion method, or a combination thereof. As shown in FIG. 1, the first fixing liquid coating device 30 is applied by spraying.

As shown in FIG. 1, the colloid coating device 40 is disposed on the first fixed liquid coating. After the cloth device 30. When the first fixing liquid layer 31 is coated on the lower cloth layer 20 and is moved backward to the working range of the colloid coating device 40 in synchronization with the bearing surface 11, the colloid coating device 40 can be in the first A fixed thickness layer 31 is further coated with a colloid layer 41 of a suitable thickness. After the colloid layer 41 is coated on the first fixing liquid layer 31, the colloid layer 41, the first fixing liquid layer 31 and the lower cloth layer 20 are still synchronized with the bearing surface 11 and continue to move backward. In the moving process, the first fixed liquid layer 31 coated first can be continuously crosslinked from the bottom to the top and gradually curled into a film state.

Further, in the first embodiment, the first fixed liquid layer 31 is first coated on The lower layer 20 is then further coated on the first fixed liquid layer 31, so the first layer The fixing liquid layer 31 is first in contact with the lower cloth layer 20 and may be infiltrated into the inner layer from the upper surface (or upper and lower surfaces) of the lower cloth layer 20. In terms of actual cross-linking, when the surface of the first fixed liquid layer 31 (having a divalent metal ion) contacts the colloid layer 41, it immediately crosslinks and begins to curl, so that in the second The contact surface between the two forms a thin film at the same time, and the thin film has the same shielding surface to prevent the colloid layer 41 from being covered by the upper surface (or upper and lower surfaces) of the lower layer 20.

After the second fixing liquid layer 51 is coated on the colloid layer 41, the second fixing liquid layer 51, the colloid layer 41, the first fixing liquid layer 31, and the lower cloth layer 20 are together (visible For the adhesive bonding, the carrier surface 11 is synchronously transported backward, and in the moving motion, the second coating liquid layer 51 which is subsequently coated can be continuously crosslinked from the upper and lower layers to the colloid layer 41. And gradually curing into a film state, that is, the colloid layer 41 is cross-linked by the first fixing liquid layer 31 from the bottom to the top and the second fixing liquid layer 51, and The bearing surface 11 is synchronously transported backwards and moved downwards The film layer 20 is gradually shaped to form a film 100 (31, 41, 51) of a suitable thickness as shown in Fig. 1, so that the curing time of the film state of the colloid layer 41 can be reduced. More specifically, the shaped adhesive film 100 (31, 41, 51) is formed by crosslinking the first fixed liquid layer 31 and the second fixed liquid layer 51 with the centered colloid layer 41, so that The film 100 after the shaping in Fig. 1 is represented by (31, 41, 51). Further, the film 100 (31, 41, 51) is continuously formed on the lower layer 20 which is transported backward and backward with the carrying surface 11, so that the film 100 (31, 41, 51) is actually produced. And the lower fabric layer 20 is closely attached to form a continuous strip 101 (20, 31, 41, 51) and can be synchronously transported with the bearing surface 11, and then outputted from the output end 12 of the bearing surface 11 The bearing surface 11 is then moved back for subsequent operations. Since the film 100 (31, 41, 51) is bonded to the lower layer 20 to form a continuous strip 101 (20, 31, 41, 51) when leaving the bearing surface 11, the first film is The continuous strip 101 is represented by (20, 31, 41, 51). However, when the consumer is in use, the film 100 (31, 41, 51) can be easily separated from the lower layer 20 (refer to the latter paragraph), and therefore, the first embodiment constitutes a carrierless wet type. The continuous film forming process of the film enables continuous and rapid production of a carrier-free wet film 100 (31, 41, 51) to achieve mass production and cost reduction.

In addition, the material of the first fixed liquid layer 31 or the second fixed liquid layer 51 is mainly The fixing liquid required for forming the film is a salt compound, but in actual production, the material of the first or second fixing liquid layer 31, 51 may be additionally added as needed with the mask (such as whitening, anti-mite removal). Etc.) Add or include other special ingredients such as beauty essences.

Referring to FIG. 2, the second embodiment and the first embodiment shown in FIG. 1 The difference between the two is that the second embodiment further provides an upper layer input device 80 between the colloid coating device 40 and the second fixing solution coating device 50 for providing An upper fabric layer 81, wherein in the second figure, the upper fabric layer 81 is first flatly attached to the colloid layer 41 and then the second fixing liquid layer 51 is coated on the upper fabric layer 81. on. Since the upper layer 81 is in contact with the colloid layer 41, the colloid layer 41 can penetrate the lower surface of the upper layer 81 and penetrate into the inner layer, so that the second fixing liquid layer 51 is coated again. When the upper layer 81 of the colloid layer 41 has been infiltrated, the second fixing liquid layer 51 can penetrate the upper surface of the upper layer 81 to penetrate into the inner layer to penetrate the upper layer 81. The colloid layer 41 of the inner layer is cross-linked, so that the colloid layer 41 is cross-linked from the bottom to the top and the second fixing liquid layer 51 by the first fixing liquid layer 31 to make the upper layer The cloth layer 81 is sandwiched or contained between the second fixing liquid layer 51 and the colloid layer 41, so that the lower cloth layer 20 is in the lower cloth layer 20 in the process of synchronously moving backward with the bearing surface 11 A film 110 (31, 41, 81, 51) of a suitable thickness and comprising the upper layer 81 is gradually formed on the upper surface as shown in Fig. 2, thus constituting a continuous film formation with a carrier wet film. Process.

In the second embodiment, the upper layer input device 80 provides the upper layer 81 It is designed as a continuous strip of cloth but is not intended to limit the invention. As shown in Fig. 2, the continuous strip-shaped upper fabric layer 81 is wound into a bundle to serve as the supply source 82 of the upper fabric layer 81 for continuously providing the upper fabric layer 81, and the upper fabric layer 81 can be provided. Flatly correspondingly attached to the colloid layer 41; wherein the upper fabric input device 80 can facilitate the operation of the upper fabric input device 80 by other mechanical components such as a reel wheel 83 or a combination of components such as a cymbal wheel set or the like. The accuracy of the operation or the improvement of the operation is such that the upper fabric layer 81 can be easily and accurately flattened and attached to the colloid layer 41.

In addition, a time point at which the second fixing liquid layer 51 is coated on the upper cloth layer 81 and the The order in which the upper cloth layer 81 is flatly corresponding to the time point of being attached to the colloid layer 41 is not particularly limited in the present invention; as shown in FIG. 2, if the upper cloth layer 81 is flatly correspondingly Pasting on the colloid layer 41 and then (or simultaneously) coating the second fixing liquid layer 51 by spraying up and down On the upper layer 81, a continuous film forming process with a carrier wet film is formed; however, as shown in FIG. 3, the second fixing liquid layer 51 is first coated by the immersion method. The upper layer 81 is then evenly coated on the colloid layer 41 with the layer 81 coated on the second fixing layer 51, because of the gap between the upper layer 81 and the colloid layer 41. The second fixing liquid layer 51 is already present on the contact surface. Therefore, although the upper cloth layer 81 is present in FIG. 3, the upper cloth layer 81 can be easily removed from the formed film 110 (31, 41, 81, 51) separation (refer to [0028]), so Figure 3 shows a continuous film formation process for forming a carrierless wet film.

As shown in FIG. 2, since the film 110 is from the lower side of the first fixed liquid layer 31 The upper and second fixing liquid layers 51 are formed by the upper cloth layer 81 and cross-linked by the upper and lower layers to the colloid layer 41, so that the formed film 110 (31, 41, 81, 51) is formed. The upper fabric layer 81 is not easily separated from the adhesive film 110 (31, 41, 81, 51). Therefore, the second embodiment (as shown in FIG. 2) is compared with the first embodiment (as shown in FIG. 1), and the film 110 (31, 41, 81, 51) of the second embodiment includes the same. The upper fabric layer 81 is integrally formed and continuously formed on the fabric layer 20 which is transported back and forth in synchronization with the carrying surface 11. It can be seen that, in actual production, the film 110 (31, 41, 81, 51) and the lower cloth layer 20 are bonded into a continuous strip 111 (20, 31, 41, 81, 51), for example. As shown in FIG. 2, the continuous strip 111 (20, 31, 41, 81, 51) can be transported synchronously with the carrying surface 11 and then outputted backward by the output end 12 of the carrying surface 11 to leave the The bearing surface 11 is used for subsequent operations, so that the film 110 (31, 41, 81, 51) still forms a bonding state with the lower cloth layer 20 to form the continuous strip 111 when performing subsequent operations (20, 31, 41, 81, 51); but in actual use (such as cutting into a mask type for consumers), the film 110 (31, 41, 81, 51) can easily be used with the lower The cloth layer 20 is separated (refer to the above [0028]), but the film 110 (31, 41, 81, 51) of the second embodiment already contains the cloth. Layer 81 is considered to be a carrier wet film in the present invention. Therefore, the second embodiment is a continuous film forming process for forming a carrier wet film for continuously and rapidly producing a carrier-containing wet film 110 (31, 41, 81, 51). The effect of production and cost reduction.

In addition, the arrangement of the upper layer input device 80 is utilized and the upper layer is provided The function of 81, the continuous film forming process of a carrierless wet film can be converted into a continuous film forming process with a carrier wet film as shown in Fig. 1 (first embodiment) as shown in Fig. 2 ( The second embodiment), therefore, the manufacturing end can be easily selected according to the needs of the consumer end to determine the production of the carrier-free or carrier-free wet film, so that not only can mass production and cost reduction be achieved, but also the wet type can be enhanced. The selectivity of the film at the consumer end and the ease of use.

The cross-linking control zone 60 includes at least one cross-linking control device (60), but is not limited. As shown in Figures 1 to 5, the cross-linking control zone 60 includes three and two spray (spray) types. The cross-linking control device (60) is respectively disposed above and below the bearing surface 11 (or the lower fabric layer 20) but is not limited. The cross-linking action control zone 60 (or the cross-linking action control device 60) mainly functions as the formed film 100 (31, 41, 51) as shown in Fig. 1 or the film 110 (31, 41, 81, 51) Providing a cleaning operation as shown in Fig. 2 so that the film 100 (31, 41, 51) or the film 110 (31, 41, 81, 51) which is being cross-linked and gradually shaped can be borrowed again. The cross-linking action between the fixed liquid layers 31, 51 and the colloid layer 41, such as washing (such as using pure water), is not completed, by the cleaning work provided by the cross-linking control zone 60. Cross-linking action between one part of the fixing liquid (31, 51) or direct suspension (such as the use of crosslinking action stop liquid) between the fixing liquid layers 31, 51 and the colloid layer 41, thereby controlling or suspending the second The degree of crosslinking and shaping between the fixed liquid layer 51 and the colloid layer 41, for example, by the intersection When the cleaning operation time or the length of the movement of the joint control zone 60 is long, a part of the fixing liquid (31, 51) in the fixed liquid layer (31, 51) can be washed away to relatively reduce the fixed liquid layer (31, 51) and the The time and extent of cross-linking and shaping between the colloid layers 41 can be prevented from being over-shaped, thereby increasing the formed film 100 (31, 41, 51) or the film 110 (31, 41, 81, 51).
