Description

Mask manufacturing device

[0001] The present invention relates to a mask manufacturing device, and more specifically, to a mask manufacturing device capable of manufacturing a mask that not only improves airtightness on the face but also prevents discomfort when worn by forming the directions of the folds formed at the position covering the user's nose bridge in the mask in opposite directions to secure space for the part covering the user's nose.

[0002]

[0003] In general, dust is generated in working environments such as paper mills, textile factories, and quarries, and large amounts of toxic gases are produced in working environments of various chemical plants and metal processing plants, such as those for welding and plating.

[0004] If workers continuously inhale such dust or toxic gases, it can not only cause respiratory diseases such as lung problems but, in severe cases, be fatal; therefore, they wear masks to protect their health from hazardous environments.

[0005] In addition, the use of masks has been increasing recently to prevent the spread of respiratory infectious diseases such as COVID-19.

[0006] A conventional mask comprises: a front portion in the form of a pleat formed by folding the front surface of the mask fabric (filter paper made of non-woven fabric) several times; a hard finishing portion formed by ultrasonically heat-welding both sides of the fabric together with a hanging band; and a metal wire (nose bridge or nose line) formed on the upper part of the fabric that can be freely folded; wherein the metal wire is configured to be folded to fit the contour of a user's face with severe curvature to ensure close contact, and furthermore, the pleat portion of the front surface of the fabric is unfolded to ensure even contact with the wearer's nose and lower chin to increase dust filtration efficiency.

[0007] As an example of such a conventional mask manufacturing device, there is a technology described in Korean Registered Patent No. 10-2555641, the technical features of which include a fabric supply unit (20) for supplying a fabric (1) as shown in FIGS. 1 and 2; a nose piece supply unit (30) for supplying a nose piece; and a fabric welding unit (40) for fixing the nose piece by welding the fabric (1) into which the nose piece is inserted, wherein the fabric welding unit (40) performs a welding process by adjusting the welding pressure corresponding to the conveying speed of the fabric (1), the fabric welding unit (40) comprises: a welding die roller (41); an up-down guide bracket (42) fixedly installed on the bottom surface of a base frame; and a slider (43) installed to be movable up and down on the up-down guide bracket (42). The apparatus is characterized by comprising: a welding machine (44) mounted on the above slider (43) and welding the above fabric (1) by applying pressure to the above welding die roller (41); a pneumatic cylinder (45) fixedly installed on the bottom surface of the above up-down guide bracket (42) to move the above slider (43) up and down and adjusting the pressure of the welding machine according to programming; a load cell that detects the pressure of the above welding machine (44); and a wrinkle forming unit (50) for forming wrinkles on the fabric.

[0008] However, although the technology described in Korean Registered Patent No. 10-2555641 has the advantage of being able to easily produce a general mask, there is a problem of discomfort when wearing it because the folds formed in the manufactured mask are formed only in the same direction, and the cut ends for forming the folds press against the bridge of the user's nose.

[0009]

[0010] The present invention has been devised to solve the above-mentioned problems, and the objective of the present invention is to provide a mask manufacturing device capable of manufacturing a mask that can improve airtightness by adhering closely to the wearer's face, such as the bridge of the nose, cheeks, and chin, without a nose wire, by forming the directions of the creases formed at the location where the user's nose bridge contacts the mask in opposite directions.

[0011] In addition, another objective of the present invention is to provide a mask manufacturing device that can form wrinkles more stably even when performing a rapid process, by providing a double inner support plate that is inserted into the part covering the part contacting the nose bridge and supports both sides, in the upper part of the wrinkle pressurizing part provided at the rear of the wrinkle roller part, in which inclined surfaces are formed in opposite directions to form wrinkles in the upper and lower parts of the part contacting the wearer's nose bridge in the wrinkle forming unit that forms wrinkles in the mask in opposite directions.

[0012]

[0013] The present invention for solving these problems is as follows:

[0014] It is characterized by comprising a fabric supply unit installed at one upper end of a base frame for supplying fabric, a pleat forming unit installed at the upper end of the base frame for forming pleats in the fabric supplied from the fabric supply unit, and a fusion cutting unit installed at the other upper end of the base frame for fusing and cutting the pleated fabric discharged from the pleat forming unit.

[0015] Here, the pleating unit is characterized by being composed of a pleating roller section that forms a plurality of pleats on a fabric and forms a continuous pleat on one side in the opposite direction, and a pleating pressing section that presses the pleat formed by the pleating roller section to complete the pleat.

[0016] At this time, the above-mentioned wrinkle pressing part is characterized by being provided with two inner support plates that support wrinkles formed in opposite directions from the inner side to the outer side.

[0017] In addition, the above-described pleated roller portion comprises an upper roller that presses the upper part of the fabric and a lower roller that presses the lower part of the fabric, wherein the upper roller comprises a plurality of first inclined protrusions with inclined surfaces formed in one direction and second inclined protrusions with inclined surfaces formed in the other direction, and the lower roller comprises a first inclined groove with an inclined surface formed to correspond to the inclined surface of the first inclined protrusion and a second inclined groove with an inclined surface formed to correspond to the second inclined protrusion.

[0018] At this time, a gap is formed between the first inclined protrusion and the second inclined protrusion, and a gap protrusion inserted into the gap is formed between the first inclined groove and the second inclined groove so that wrinkles are formed in different directions.

[0019] Meanwhile, the above-mentioned wrinkle pressurizing member is characterized by comprising a pair of supports, a plurality of first outer support plates installed on one support at a predetermined distance apart in the vertical direction to support the wrinkle from the outside to the inside, and a plurality of inner support plates installed on the other support, the ends of which are inserted between the first outer support plates to support the wrinkle from the inside to the outside.

[0020] Here, the pressure pleating portion further includes a second outer support plate installed on the other side support at the same height as the uppermost first outer support plate among the first outer support plates to support the pleating from the outside to the inside, and the two inner support plates are provided to cover the upper part of the space between the first outer support plate and the second outer support plate.

[0021] At this time, the first outer support plate is formed such that the length of its end becomes shorter as it extends downward by a distance corresponding to the spacing of the first inclined protrusion, and the inner support plate is formed such that the length of its end becomes longer by a distance corresponding to the spacing of the first inclined protrusion.

[0022] In addition, the fusion cutting unit is characterized by comprising a fusion roller that fuses both sides of a wrinkled fabric, a cutting roller that fuses the cut portions while cutting the fabric with both sides fused at predetermined intervals, a first transfer roller located between the fusion roller and the cutting roller that supplies the fabric passing through the fusion roller to the cutting roller side, and a second transfer roller located at the rear of the cutting roller that pulls and discharges the cut fabric.

[0023] In addition, a folding unit is further provided at the front of the fusion cutting unit, wherein the folding unit is characterized by being composed of a support plate that supports the lower part of the fabric and a pair of folding guide members provided on both sides of the support plate that fold both sides of the fabric upward.

[0024] At this time, the pair of folding guide members are characterized by being installed at a distance narrower than the width of the fabric.

[0025] In addition, the above-mentioned corrugated pressure part is further provided with a support frame, wherein the inner support plate and the first and second outer support plates are inserted into the inner side of the support frame, and a fixing bolt is provided on the upper side of the support frame to press the first outer support plate or the second outer support plate from above.

[0026] Here, the support member is installed at the lower part of the above-mentioned pleated pressure member so as to be rotatable.

[0027]

[0028] According to the present invention with the above-described configuration, by forming the directions of the creases formed at the location where the user's nose bridge contacts the mask in opposite directions, it is possible to manufacture a mask that can be closely attached to the wearer's face, such as the nose bridge, cheeks, and chin, without a nose wire, thereby improving airtightness.

[0029] In addition, the present invention has the effect of forming wrinkles more stably even when performing the process quickly by providing a double inner support plate that is inserted into the part covering the part contacting the nose bridge and supported on both sides, in the upper part of the wrinkle pressing part provided at the rear of the wrinkle roller part, which has inclined surfaces formed in opposite directions to form wrinkles in opposite directions at the upper and lower parts of the part contacting the wearer's nose bridge in a wrinkle forming unit that forms wrinkles in a mask.

[0047] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings. Identical components in the drawings are denoted by the same reference numerals, and redundant descriptions of identical components are omitted. Furthermore, it should be understood that the present invention can be implemented in a number of different forms and is not limited to the described embodiments.

[0048]

[0049] The present invention relates to a mask manufacturing device, and as illustrated in FIGS. 4 to 8, the configuration comprises a base frame (100) that supports the lower part, a fabric supply unit (200) installed at one upper end of the base frame (100) to supply a fabric (500), a wrinkle forming unit (400) installed at the upper part of the base frame (100) to form wrinkles on the fabric (500) supplied from the fabric supply unit (200), and a fusion cutting unit (300) installed at the other upper end of the base frame (100) to fuse and cut the wrinkled fabric (500) discharged from the wrinkle forming unit (400).

[0050] Here, a plurality of fabric guide rollers (110) are provided between the pleat forming unit (400) and the fusion cutting unit (300) to support and guide the fabric (500) discharged from the pleat forming unit (400) from the upper or lower side.

[0051] At this time, the fabric guide roller (110) may be installed only between the pleat forming unit (400) and the fusion cutting unit (300) as described above, but may also be installed at various places on the upper part of the base frame (100) to stably guide the movement of the fabric (500).

[0052] Therefore, by automatically performing the entire process of manufacturing the mask (600), it becomes possible to manufacture high-quality masks more quickly.

[0053] And, the fabric supply unit (200) supplies a fabric (500) for manufacturing a mask (600), and the fabric (500) is composed of a filter (510) for filtering out foreign substances and a cover member (520) that covers the front and rear of the filter (510).

[0054] Here, the fabric supply unit (200) is composed of a winding drum (210) on which a filter (510) and a cover member (520) are wound on the upper part of one end of the base frame (100), and a speed control unit (not shown) that supplies them at a constant speed, thereby stably supplying the fabric (500).

[0055] Meanwhile, the wrinkle forming unit (400) for forming a plurality of wrinkles in the fabric (500) is composed of a wrinkle roller part (410) that forms wrinkles formed on the upper and lower sides of the part (610) covering the bridge of the nose in opposite directions, and a wrinkle pressing part (440) that presses the wrinkles formed by the wrinkle roller part (410) to complete the wrinkles.

[0056] Here, the pleated roller section (410) is composed of an upper roller (420) that presses the upper part of the overlapping fabric (500) and a lower roller (430) that presses the lower part of the overlapping fabric (500). The upper roller (420) is composed of a plurality of first inclined protrusions (422) that form an inclined surface in one direction and second inclined protrusions (424) that form an inclined surface in the other direction.

[0057] At this time, the lower roller (430) is composed of a first inclined groove (432) in which an inclined surface is formed to correspond to the inclined surface of the first inclined protrusion (422), and a second inclined groove (434) in which an inclined surface is formed to correspond to the second inclined protrusion (424).

[0058] Thus, the upper and lower parts of the nose bridge covering portion (610) in the fabric (500) located between the upper roller (420) and the lower roller (430) are made to have wrinkles formed in different directions by the first and second inclined protrusions (422, 424) and the first and second inclined grooves (432, 434).

[0059] And, a gap (426) is formed between the first inclined protrusion (422) and the second inclined protrusion (424), and a gap protrusion (436) inserted into the gap (426) is formed between the first inclined groove (432) and the second inclined groove (434).

[0060] Accordingly, the above-mentioned gap (426) and gap protrusion (436) form a portion (610) that covers the wearer's nose bridge in the fabric (500). As described above, the wrinkles formed on the upper and lower parts of the flat portion formed by the gap (426) and gap protrusion (436) are formed in different directions by the first and second inclined protrusions (422, 424) and the first and second inclined grooves (432, 434), thereby enabling stable securing of the space for the portion (610) that covers the nose bridge, as illustrated in FIG. 6.

[0061] Meanwhile, as described above, the fabric (500) in which wrinkles are formed first by the wrinkle roller part (410) moves to the wrinkle pressing part (440) located at the rear, and wrinkles are formed more completely on the fabric (500) by the wrinkle pressing part (440).

[0062] Here, the above-mentioned corrugated pressure member (440) is formed by including a pair of supports (441), a plurality of first outer support plates (442) installed on one side of the support (441) at a predetermined distance apart in the vertical direction, and a plurality of inner support plates (444) installed on the other side of the support (441), as shown in FIGS. 7 and 8.

[0063] At this time, the first outer support plate (442) is installed on one side support (441) at a predetermined distance in the vertical direction to support the wrinkles formed on the fabric (500) from the outside to the inside, and the inner support plate (444) is installed on the other side support (441), and its end is inserted between the first outer support plates (442) to support the wrinkles from the inside to the outside.

[0064] In this way, the wrinkles formed by the wrinkle roller part (410) are more completely formed by the first outer support plate (442) and the inner support plate (444).

[0065] Additionally, the other support member (441) forming the above-mentioned pressure pleat portion (440) is further provided with a second outer support plate (443) installed at the same height as the uppermost first outer support plate (442) among the first outer support plates (442) to support the pleat from the outside to the inside.

[0066] Here, two inner support plates (445) are additionally provided to cover the upper part of the gap space formed between the first outer support plate (442) and the second outer support plate (443), and the two inner support plates (445) support the wrinkles formed on the upper and lower sides of the part (610) covering the bridge of the nose from the inside to the outside.

[0067] At this time, the inner support plates (445) are formed long along the longitudinal direction, and a reinforcing bar (446) is installed at the lower part of the support member (441), and a support bracket (447) is installed on the reinforcing bar (446) to protrude forward and is connected to support the lower part of the inner support plates (445).

[0068] Therefore, the above-mentioned two inner support plates (445) support the wrinkles formed on the upper and lower sides of the part (610) covering the wearer's nose bridge, formed by the above-mentioned spacing part (426) and spacing protrusion (436), from the inner side to the outer side, thereby allowing the wrinkles formed on the upper and lower sides of the part (610) covering the nose bridge to be formed more completely in opposite directions.

[0069] Additionally, as shown in FIG. 8, the first outer support plate (442) is formed such that the length of the end becomes shorter as it goes downward by a distance corresponding to the spacing of the first inclined protrusion (422), and the inner support plate (444) is formed such that the length of the end becomes longer by a distance corresponding to the spacing of the first inclined protrusion (422), thereby allowing the wrinkles forming the mask (600) to be formed sequentially.

[0070] Here, as another embodiment of the present invention, as shown in FIG. 14, two second inclined protrusions (424) are formed at one end of the upper roller (420') that forms the corrugated roller (410'), and two second inclined grooves (436) are also formed at one end of the lower roller (430') to correspond thereto.

[0071] Therefore, the cross-sectional shape of the mask (600) that has passed through the above-mentioned pleated roller (410') and pleated pressure part (440) is formed as shown in FIG. 15, so that the nose portion can be accommodated more stably.

[0072] Of course, although not shown in the drawing, a pair of upper and lower inner support plates (445) constituting the above-mentioned corrugated pressure part (440) are provided, and the thickness of the lower inner support plate (445) is formed wider, and the second outer support plate (443) is also provided upper and lower to form the shape of the mask (600) as shown in FIG. 15.

[0073] Meanwhile, as described above, a fabric guide roller (110) is provided between the fusion cutting unit (300) and the wrinkle forming unit (400) to supply the fabric (500) to the fusion cutting unit (300) in a state where wrinkles are formed on the fabric.

[0074] Here, the fusion cutting unit (300) comprises a fusion roller (310) that fuses both sides of a wrinkled fabric (500) and a cutting roller (320) that fuses the cut portions while cutting the fabric (500) that has both sides fused at predetermined intervals.

[0075] At this time, the fusion cutting unit (300) is further equipped with a first transfer roller (330) positioned between the fusion roller (310) and the cutting roller (320) to supply the fabric that has passed through the fusion roller (310) to the cutting roller (320) side, and a second transfer roller (340) positioned behind the cutting roller (340) to pull and discharge the cut fabric (500).

[0076] Therefore, as the wrinkled fabric (500) passes through the above-mentioned fusion cutting unit (300), both sides of the fabric (500) are fused together with the wrinkles, and the cut portions are fused while cutting the front and rear directions of the fabric (500) to produce a mask (600).

[0077] Additionally, the cutting roller (320), the first transfer roller (330), and the second transfer roller (340) constituting the fusion cutting unit (300) are formed as an upper and lower pair, and a support member (not shown) that supports the lower part of the fabric (500) is provided at the lower part of the fusion roller (310).

[0078] Here, plate-shaped support brackets (352) are installed on both sides of the fusion cutting unit (300), and the support brackets (352) are provided with a lifting bracket (354) in which the ends of the fusion roller (310), cutting roller (320), first transfer roller (330), and second transfer roller (340) are rotatably installed, and the lifting bracket (354) is installed so as to be movable up and down on the support brackets (352).

[0079] At this time, the upper part of the support bracket (352) is provided with an adjustment knob (356) that can move the lifting bracket (354) up and down, thereby allowing the vertical distance between the welding roller (310), the cutting roller (320), the first transfer roller (330), and the second transfer roller (340) to be adjusted.

[0080] Therefore, the spacing can be appropriately adjusted according to the thickness of the supplied fabric (500), making it possible to produce a mask (600) of higher quality.

[0081] Additionally, a folding unit (360) is further provided at the front end of the fusion cutting unit (300), and as shown in FIG. 10, the folding unit (360) consists of a support plate (362) that supports the lower part of the fabric (500) and a pair of folding guide members (364) provided on both sides of the support plate (362) to fold both sides of the fabric (500) upward.

[0082] Here, the pair of folding guide members (354) are installed at a distance narrower than the width of the fabric (500) so that both sides of the fabric (500) can be easily folded upward. As described above, a welding roller (310) is provided at the rear of the folding unit (350) so that after the edges of the fabric (500) are folded upward, they are welded in a completely folded state by the welding roller (310).

[0083] At this time, the cover member (520) constituting the fabric (500) is composed of a lower cover (522) located at the bottom and in contact with the wearer, and an upper cover (524) located at the top, wherein the lower cover (522) is formed to protrude laterally more than the filter member (510) and the upper cover (224).

[0084] So, when folded, the edge of the lower cover (522) is folded so that it is fused to cover the edge of the upper cover (224).

[0085] Therefore, if the colors of the lower cover (522) and the upper cover (524) are different, the color of the lower cover (522) covers the edge of the upper cover (524), thereby improving the color and making it possible to manufacture a fashionable mask (600).

[0086] Meanwhile, as another embodiment of the present invention, as shown in FIG. 12, the folding unit (360) may be installed in an inverted state so that the width of the upper cover (524) is wider than the width of the lower cover (522), and the edge of the upper cover (524) is folded downward so that the edge of the lower cover (522) is covered from below and fused.

[0087] In addition, as another embodiment of the present invention, as shown in FIG. 13, the corrugated pressure member (440') is located on the inside of a support frame (450) provided on the outside, and the inner support plate (444) and the first and second outer support plates (442, 443) constituting the corrugated pressure member (440') are provided so as to be detachably attached to the inside of the support frame (450).

[0088] Here, a fixing screw (452) is provided on the upper part of the support frame (450) to press and fix the upper part of the inner support plate (444) and the first and second outer support plates (442, 443) that are stacked, so that when replacement is needed, the fixing screw (452) can be loosened and easily replaced.

[0089] At this time, the support member (441') installed at the lower part of the support frame (450) is formed to be rotatable, and a control screw (454) for controlling the rotational state is provided on the side of the support member (441'), thereby enabling the rotational state to be maintained.

[0090] Therefore, when replacing any one of the inner support plate (444) and the first and second outer support plates (442, 443), the adjustment screw (454) is loosened, and the support frame (450) is rotated so that the ends of the inner support plate (444) and the first and second outer support plates (442, 443) do not cross, making it easier to separate or insert them.

[0091]

[0092] Although preferred embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to those within a substantially equivalent range to the embodiments of the present invention. Various modifications can be made by those skilled in the art to which the present invention belongs, without departing from the spirit of the present invention.
