Description

The present invention generally relates to industrializing the manufacture of false eyelashes. More particularly, the present invention relates to a method for manufacturing false eyelashes, especially tufted false eyelashes. The invention also relates to a system for manufacturing false eyelashes. The invention further relates to false eyelashes manufactured using such methods and/or systems.

Many women today use false eyelashes for cosmetic purposes on a daily or occasional basis. The most commonly used are tufted false eyelashes having a structure in which a plurality of eyelash fibers are connected parallel to each other via a baseline. Generally, false eyelashes, especially tufted false eyelashes, are manufactured by hand one by one because of their delicate structure. This labor-intensive method results in low productivity and extremely high manufacturing costs.

In order to solve this problem, automatic production of false eyelashes has been attempted. However, due to the difficulty of balancing the natural appearance of the resulting product with high productivity and low manufacturing costs, a completely satisfactory method for automation has not yet been established.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the current problems arising from manual reliance on manufacturing. Specifically, it is an object of the present invention to provide an automated manufacturing technique for false eyelashes that can achieve at the same time a natural appearance of the resulting product, high productivity and low manufacturing costs.

To achieve the aforementioned objects, the present invention provides a method for producing tufted false eyelashes in which a plurality of eyelash fibers are connected parallel to each other via a baseline. In the present invention, the method comprises feeding a plurality of heat-fusible raw fibers, each forming a pair of lash fibers, parallel to each other onto a platform, the platform being oriented perpendicular to the fed raw fibers. and a base line extending in tension along a direction perpendicular to the feedstock fibers to be fed to the platform. feeding over an opening with the plurality of rows of raw fibers interposed therebetween; and lowering the fed baseline through the opening of the platform and into the cavity of the platform. forcing a plurality of rows of feedstock fibers into cavities of the platform by placing them into the cavities of the platform, thereby bending the feedstock fibers into a V-shape about the baseline; Bonding (eg, by pressing and heating) at the intersection of the raw fibers and the baseline, thereby forming a precursor of the tufted false eyelashes.

The present invention also provides a system for producing tufted false eyelashes in which a plurality of eyelash fibers are connected parallel to each other via a baseline. In accordance with the present invention, the system includes a plurality of sources of heat-fusible raw fibers each forming a pair of lash fibers, a source of baselines, and a joining unit for joining the raw fibers and the baselines. . The connecting unit is a platform on which a plurality of raw material fibers are supplied in parallel to each other, and has an opening formed on its upper surface so as to extend in a direction orthogonal to the supplied raw material fibers, and an opening a platform including a cavity leading from the base; and a baseline holder positioned above the platform for lowering into the platform cavity through an opening in the platform, the baseline a baseline holder configured to hold the baseline at its lower end so as to extend in tension along a direction orthogonal to the feedstock fibers to which the base line is supplied; , and a pair of heating heads arranged to be projectable into and retractable from the cavity of the platform. The baseline holder pushes a plurality of rows of feedstock fibers into the platform cavity by lowering the baseline through the opening of the platform and into the cavity of the platform, thereby causing the feedstock fibers to be V-shaped around the baseline. Constructed to bend into shape. A pair of heating heads bends the source fiber and then bonds the source fiber and the baseline at the intersection of the source fiber and the baseline (for example, by pressing and heating), thereby forming tufts. It is configured to form precursors of eyelashes.

According to the present invention, it is possible to industrially manufacture tufted false eyelashes, which have conventionally been manufactured manually one by one due to their delicate structure, without relying on human hands. is. This means that the production of tufted false eyelashes can be fully automated. As a result, according to the present invention, high productivity and low manufacturing costs for manufacturing tufted false eyelashes can be realized. Specifically, in the present invention, the raw material fibers of the eyelash fibers are bent around the baseline by pressing the baseline that is held in tension in a direction orthogonal to the raw material fibers. In this state, the raw fibers and the baseline are consolidated by bonding their intersections, for example by applying pressure and heat. With this method it is possible to achieve tufted false eyelashes with a more natural appearance compared to those obtained by conventional manufacturing methods. This is because the false eyelashes obtained by this method have a two-layer fiber structure that contributes to making the false eyelashes look more natural. In addition to this, according to the method, the end of the eyelash fiber on the side of the user's eye is bent into a loop, so that the tip or edge of the fiber can be prevented from being dangerous. This is a discovery made by the inventor for the first time.

According to a preferred aspect of the present invention, the method may further comprise the step of aligning the raw fibers at regular intervals before feeding the raw fibers onto the platform. This can be done, for example, by placing a comb member or the like through which the raw fibers pass in front of the platform.

According to one preferred aspect of the present invention, the step of bonding comprises using two heating heads facing each other and displaceable toward or away from each other, at the intersection of the source fibers and the baseline. pressing and heating. According to another preferred aspect of the invention, the step of bonding may comprise induction heating or ultrasonic heating.

According to a preferred embodiment of the invention, each of the raw fibers can be supplied in the form of continuous yarn. Where each of the feedstock fibers is provided in the form of a continuous yarn, the method according to one aspect of the present invention individually produces a series of precursors formed by continuously bonding the feedstock fibers and the baseline. can further comprise separating into precursors of

According to a preferred aspect of the present invention, each of the raw fibers can be supplied pre-cut to a predetermined length. In this case, the pre-cut raw fibers can be transported on a sheet or flexible support right up to the platform. If each of the raw fibers were supplied in a pre-cut state, the step of separating the series of precursors into individual precursors may be omitted. Moreover, in this case, for an even more natural appearance (like natural eyelashes) it is possible to use tapered fibers whose tips are made thinner by a chemical or mechanical process. It is possible.

According to one preferred aspect of the present invention, the method may further comprise the step of curling each precursor lash fiber by thermoforming. In addition, according to one preferred aspect of the present invention, the method may further comprise forming the baseline of the precursor into an arcuate shape by thermoforming. These two thermoforming processes can be performed simultaneously as one step. Alternatively, these two thermoforming steps can be performed with potentially two different sets of parameters (i.e., temperature and time) to perform lash fiber thermoforming followed by baseline thermoforming, or vice versa. To be performed in order, they can be performed sequentially over time.

According to one preferred aspect of the present invention, the baseline holder may include a main body and a pair of protrusions protruding downward from the lower surface of the main body. In this case, the protrusions may be spaced apart from each other by a width greater than the width of the row of raw fibers fed onto the platform, and the baseline may be held at the tips of the protrusions.

According to one preferred aspect of the present invention, the pair of heating heads are positioned between the lower surface of the body of the baseline holder and the bottom surface of the cavity of the platform with the baseline holder fully lowered into the cavity of the platform. It may be configured so that it can protrude into the space formed therebetween.

According to one preferred aspect of the present invention, the system includes a separation unit for separating a series of precursors formed by successively bonding raw fibers and baselines into individual precursors. It can contain more.

According to one preferred aspect of the present invention, the system comprises a thermoforming to curl each precursor lash fiber and/or a thermoforming to arcuately form the precursor baseline. It may further include a thermoforming unit.

In addition to the above, the present invention also includes a plurality of eyelash fibers each formed from a heat-fusible raw material fiber, and a baseline connecting the eyelash fibers in parallel with each other, each raw material fiber being centered on the baseline. Folded to form two or paired eyelash fibers, the eyelash fibers and the baseline are thermally bonded at their intersections to provide tufted false eyelashes produced by the method described above.

FIG. 1 schematically shows a system S for manufacturing tufted false eyelashes, which is an exemplary embodiment of the invention. FIG. 1 further shows a tufted false eyelash 1, which is also an exemplary embodiment of the invention, manufactured by system S. FIG. As shown in FIG. 1, the tufted false eyelashes 1 (hereinafter simply referred to as "false eyelashes") consist of a plurality of eyelash fibers 10 and a baseline 20 connecting these eyelash fibers 10 in parallel. include.

Each of the plurality of eyelash fibers 10 is formed from heat-fusible raw material fibers 10' described later. The heat-fusible raw material fibers 10' can be made of, for example, a heat-fusible resin such as polyamide (PA) or polybutylene terephthalate (PBT). Also, the baseline 20 can be made from the same material as the lash fibers 10 or from a different material. In this false eyelash 1 shown as an exemplary embodiment of the present invention, one raw fiber 10' is folded about a baseline 20 to form two or a pair of eyelash fibers 10, and the eyelash fibers 10 and baseline 20 are thermally coupled at their intersection.

In this embodiment, each of the raw fibers 10' is supplied from a source 100 in the form of a continuous thread, as previously described. In one embodiment of the present invention, the number of feedstock fibers 10' supplied from the source 100 ranges from five to several tens, and the diameter of the feedstock fibers 10' and/or the baseline 20 is about 0.1mm to 0.8mm. can be, but is not limited to.

As shown in FIG. 2, alignment unit 200 of system S includes comb members 210 having a plurality of comb teeth (not shown). A plurality of raw fibers 10 ′ supplied from the source 100 are intermittently transferred to the combining unit 300 through the gaps between the comb teeth of the comb member 210 . Alignment unit 200 uses comb members 210 to align a predetermined distance D (e.g., about 0.1 mm to a few mm) are aligned. In another embodiment, this alignment step can be performed as in a fabric weaver using multiple loops or holes. Moreover, in yet another embodiment, this distance D may not be constant. For example, the distance between the first two fibers may be D, the distance between the next two fibers may be different from D, and then back to D again.

A connecting unit 300 installed next to the aligning unit 200 connects rows of a plurality of raw fibers 10′ supplied from the aligning unit 200 and the baseline 20 directly supplied to the connecting unit 300. FIG. As shown in FIG. 3, the joining unit 300 includes a platform 310 intermittently fed with a plurality of raw fibers 10' parallel to each other. The platform 310 includes an elongated opening 312 formed in its upper surface 316 so as to extend in a direction perpendicular to the feedstock fibers 10' and a cavity 314 leading from the opening 312. . The sides of cavity 314 may be slanted with respect to a vertical line perpendicular to top surface 316 of platform 310 such that the distance between the two sides of cavity 314 increases toward opening 312. good.

As also shown in FIG. 3, the coupling unit 300 also has a baseline holder 330 positioned above the platform 310 so that it can be lowered into the cavity 314 of the platform 310 through the opening 312 of the platform 310. including. Displacement of the baseline holder 330 in the vertical direction is performed by suitable actuators, not shown.

Baseline holder 330 holds baseline 20 supplied from source 110 at its lower end such that baseline 20 extends in tension along a direction perpendicular to feedstock fiber 10′ supplied. configured to hold. More specifically, the baseline holder 330 includes a body 332 and a pair of projections 336a, 336b projecting downward from a bottom surface 334 of the body 332. As shown in FIG. Body 332 generally has a contour that corresponds to the contour of cavity 314 of platform 310 . The protrusions 336a, 336b are spaced apart from each other by a width W1 _somewhat wider than the width _W2 of a line of raw fibers 10' intermittently fed onto the platform 310. As shown in FIG. In the exemplary embodiment, the protrusion length L of the protrusions 336a, 336b is slightly less than the space 322 formed between the baseline holder 330 and the platform 310, described below. Protrusions 336a, 336b have semi-circular notches 338a, 338b at their tips. The baseline 20, whose both ends (not shown) are positioned at a predetermined height within the coupling unit 300, is held at the tips of the projections 336a, 336b by engaging the notches 338a, 338b. It is

The baseline holder 330 lowers the baseline 20 through the opening 312 of the platform 310 and into the cavity 314 of the platform 310, thereby pushing the row of raw fibers 10' into the cavity 314 of the platform 310 and It is configured to bend the raw material fiber 10' into a V shape or an open ring shape around the baseline 20 by bending. This will be described later in detail again using FIG.

As can be seen from FIG. 4 in addition to FIG. 3, the coupling unit 300 further includes a pair of heating heads 320a, 320b that are positioned opposite each other and that can project into and retract from the cavity 314 of the platform 310. include. Specifically, the pair of heating heads 320 a , 320 b are heated to the lower surface 334 of the body 332 of the baseline holder 330 and the cavity of the platform 310 with the baseline holder 330 fully lowered into the cavity 314 of the platform 310 . It is configured to be able to protrude inside a space 322 (see FIG. 5) formed between the bottom surface 318 of 314 . In this embodiment, most of the pair of heating heads 320a, 320b are housed within the platform 310. FIG. The heating heads 320a, 320b have a vertical thickness T, which is slightly smaller than the height H of the space 322 (see FIG. 5). Horizontal displacement of the pair of heating heads 320a, 320b is effected by suitable actuators, not shown.

As shown in FIG. 6, the pair of heating heads 320a and 320b bend the raw material fiber 10′, and then press and heat the intersection of the raw material fiber 10′ and the baseline 20 to bend the raw material fiber 10′. The fiber 10' is configured to join or fuse with the baseline 20, thereby forming the precursor 1' of the tufted false eyelashes 1. In another embodiment, heating may be performed by induction heating or ultrasonic heating. In this case compression may be omitted. After bonding the raw fiber 10' with the baseline 20, the baseline holder 330 and heating heads 320a, 320b are immediately retracted to their original positions. In the present system S, the precursor 1' obtained in this joining process is drawn out of the cavity 314 of the platform 310 and fed to the next unit 400. FIG. In addition, after the raw material fiber 10' and the baseline 20 are combined, the portion of the baseline 20 protruding left and right from the baseline holder 330 is cut by cutting the raw material fiber 10 using a suitable cutter (not shown). ' is separated from the portion of baseline 20 that is bound to '. The precursor 1' thus obtained is transferred to the unit 400, whereupon the baseline 20 is bridged between the protrusions 336a, 336b of the baseline holder 330 by a suitable device not shown.

As described above, since each of the raw fibers 10' is supplied in the form of a continuous thread, in this embodiment, the series of false eyelash precursors 1' is produced by combining the raw fibers 10' with the baseline 20. It is formed. This will be described in detail again later using FIGS. 6 and 7. FIG.

The separating unit 400, which is installed next to the joining unit 300, uses a cutter (not shown) to continuously join the raw fibers 10' and the baseline 20 to form a series of precursors 1 ' into individual precursors 1'. A series of eyelash precursors 1' formed by successively joining raw fibers 10' and baselines 20 is shown in FIG. 7(a). Separation unit 400 is configured to separate precursors 1' from each other at line C-C shown in FIG. 7(a), so that the individual precursors shown in FIG. 7(b) 1' is provided. In the present system S, the individual precursors 1' thus obtained are then transferred to the thermoforming unit 500.

A thermoforming unit 500, which follows the separation unit 400, curls each eyelash fiber 10 of the precursor 1' by thermoforming using a suitable mold (not shown), and Secondly, the base line 20 of the precursor 1' is configured to be arcuately formed by thermoforming using a suitable alternative mold, also not shown. The precursor 1′ before treatment by the thermoforming unit 500 is shown in FIG. 8(a), and the precursor 1′ after treatment by the thermoforming unit 500, ie the finished tufted false eyelashes 1 is shown in FIG. 8(b). ). In one embodiment, as shown in FIG. 8(b), each eyelash fiber 10 of the false eyelashes 1 has a substantially constant (or non-constant) radius of curvature _R1 centered on the imaginary point _P1. and the baseline 20 has a substantially constant (or non-constant) radius of curvature _R2 centered on the imaginary point _P2 .

As described above, in the tufted false eyelashes 1 according to the embodiment of the present invention, one raw fiber 10' is bent around a baseline 20 to form two or a pair of false eyelash fibers 10. As a result, the tufted false eyelashes 1 have twice as many false eyelash fibers 10 as the number of raw fibers 10' supplied from the source 100.

Next, the present method for manufacturing tufted false eyelashes according to one embodiment of the present invention using the system S described above will be described in detail. However, it should be noted that the present method for manufacturing tufted false eyelashes according to the present invention may be practiced without using the aforementioned system.

In the method, first, a plurality of heat-fusible raw fibers 10', each forming a pair of eyelash fibers 10, are fed parallel to each other from a source 100 to an alignment unit 200 (see Figure 1). Here, each raw fiber 10' is in the form of a continuous thread. A plurality of raw fibers 10' supplied from a source 100 are aligned at regular intervals by an alignment unit 200 using comb members 210 (see FIG. 2). A plurality of raw fibers 10' are then fed onto platform 310 of bonding unit 300 (see FIGS. 3 and 4).

In addition to this, the baseline 20 extends from the source 110 to the platform 310 of the coupling unit 300 so as to extend in tension along a direction perpendicular to the feedstock fiber 10' (see FIGS. 3 and 4). , with a plurality of rows of raw fibers 10' placed therebetween. Baseline 20 is also in the form of a continuous thread.

Next, in the bonding unit 300, a step of bonding the plurality of raw fibers 10' and the baseline 20 is performed. More specifically, a row of raw fibers 10' is forced into cavity 314 of platform 310 by lowering baseline 20 through opening 312 of platform 310 and into cavity 314 of platform 310. . As a result, the plurality of raw fibers 10' are bent into a V-shape about the baseline 20 within the cavity 314 of the platform 310 (see FIG. 5).

After bending the raw material fibers 10', the plurality of raw material fibers 10' and the baseline 20 are bonded by pressing and heating the intersections of the raw material fibers 10' and the baseline 20. FIG. In this exemplary embodiment, the bonding process between the raw fiber 10' and the baseline 20 uses two heating heads 320a, 320b (see FIG. 6) that can be horizontally displaced toward or away from each other. , is carried out. Such steps performed intermittently one after another form a series of precursors 1' of tufted false eyelashes 1 (see Figure 7(a)).

A series of false eyelash precursors 1' and baselines 20 formed by successively joining raw fibers 10' and baselines 20 are then separated into individual precursors 1' (Fig. 7 (b)). Finally, each lash fiber 10 of the precursor 1' thus obtained is curled by thermoforming, and the baseline 20 of the precursor 1' is arcuately formed by thermoforming (see Figure 8). The thermoforming of each lash fiber 10 of the precursor 1' and the thermoforming of the baseline 20 of the precursor 1' can be performed simultaneously or in reverse order to that described above.

As described above, according to an exemplary embodiment of the present invention, tufted false eyelashes, which are traditionally manufactured individually by hand because of their delicate structure, rely on human hands. can be produced industrially, i.e. automatically, without As a result, according to an exemplary embodiment of the present invention, high productivity and low manufacturing costs for manufacturing tufted false eyelashes can be realized. Specifically, according to one exemplary embodiment of the present invention, compared to those obtained by conventional manufacturing methods, e.g. It is possible to achieve tufted false eyelashes with a more natural appearance.

FIG. 9 shows a system and method for manufacturing false eyelashes according to another embodiment of the present invention. In this alternative embodiment, unlike the previous embodiment, each raw fiber 10'' of the eyelash fibers 10 is supplied pre-cut to a predetermined length, eg, approximately 2 cm to 4 cm. The pre-cut raw fibers 10'' are transported to a position just before the joining unit 300 uses a sheet or flexible support (not shown) and then undergoes a process similar to the previous embodiment ( except for the separating step) is performed to yield the tufted false eyelashes also shown in FIG. 8(b).

According to this embodiment, the separating step required when the raw material fibers of the eyelash fibers are supplied in the form of continuous threads can be omitted.
