Description

Method of manufacturing mask

The present invention relates to a mask manufacturing method and a mask manufacturing method for forming a filter inserting bag on the front surface of the mask.

In the case of yellow dust and fine dust, it contains heavy metals such as silicon, cadmium, and lead as well as harmful contaminants. If you go directly into the lungs of the cough, sputum, inflammation and bronchial stenosis may occur, so appropriate treatment and attention is required. According to these requirements, it is possible to prevent harmful substances to some extent by wearing a mask, but the existing cloth (cotton) mask has a limited dust collection efficiency or a filter effect, so fine dust cannot be filtered out, so the dust-proof effect is limited. In case of industrial dust / gas masks, multi-layered composite filter enhances dust collection efficiency, and the rubber band that can be double clamped to the head improves adhesion to the face area, which is expected to provide high efficiency in blocking dust. It was rather limited for everyday use. In addition, by forming a plurality of filter paper by heat fusion, the ventilation resistance is increased, which makes it difficult to breathe.

In addition, known disposable masks include a pleated front portion formed by bending the entire surface of the filter paper several times, a hard finish formed by ultrasonic thermal welding of both sides of the filter paper together with a hook band, and formed on the upper portion of the filter paper. Metal wires are provided to bend the metal wires to fit the contours of the user's face, as well as to close the wrinkles on the front of the filter paper. One disposable dust mask is known.

Masks made of filter papers have a front member and a lower surface member, which are generally located toward the user's mouth and are developed upward and downward, respectively, and have a front portion at which upper and lower ends of these front and lower surfaces are fused. The front member, the lower member and the front portion are characterized by not having a seam because the end main surface is ultrasonically fused by a known technique. A mask filter fabric paper supply roller for supplying at least one fabric paper to manufacture such a mask; A pattern forming roller for forming and laminating a pattern by ultrasonic vibration on the surface of the mask filter paper fabric supplied by the sheet feeding roller, and the mask filter paper fabric formed by the pattern forming roller in the upper and lower filter papers of the mask. The first cutting roller for cutting into the shape, the upper and lower filter paper cut by the first cutting roller and the second cutting roller for receiving the fabric for the front filter paper which is supplied separately at the same time by combining them with each other and cutting in the form of a mask It is configured to include (see Patent No. 10-0783311).

Moreover, as a basic mask manufacturing apparatus, the thing of patent No. 10-1597735 (refer FIG. 1A) is known. They are commonly provided with mask fabric winding rollers at the inlet side, and the fabrics supplied from these rollers are processed through the front, top, bottom, and nose wire supply portions of the fabric lamination and the nose wire insertion, and the like. The ultrasonic fusion process is repeatedly completed through lamination, fusion, and edge cutting process.

Moreover, among these, the folding mask which spreads and wears the folded mask at the time of use is also known.

The folding mask known through Korean Patent Laid-Open Publication No. 10-2008-0102881 discloses a mask including a base panel, an upper panel, and a lower panel, and having a shape in which the base panel is curved outward in an unfolded state. The mask is divided into upper and lower surfaces so that the base panel has an outwardly curved shape, and the structure of the mask is divided into two so that the width of the upper and lower surfaces becomes smaller from the center to both ends (see FIG. 1B). .

On the other hand, the mask is a respiratory protection means for wearing so as not to inhale foreign substances such as dust floating in the air, it is made of a general air permeable fiber material. Recently, a mask incorporating a filter material filter for allowing the air sucked into the mouth and nose to be filtered through various filter materials has been proposed. In order to insert such a filtration filter, a bag for replacing the filtration filter has been required on the front or rear of the mask.

In other words, in order to manufacture a filter bag made of a non-woven fabric on the front of the existing mask, a mask manufactured by a general process consisting of a separate skin, an inner skin, etc. is conventionally placed on a lower plate jig, and a non-woven fabric separately cut thereon is placed on the mask. The upper plate jig for ultrasonic fusion forming a U-shaped melting line in the lower plate jig by pressing and fusion fusion bonding the three sides of the nonwoven fabric to provide a mask having one side is opened and the filter insert pocket. In this process, the upper and lower edges of the unfinished mask with the margin cut off are composed of curved curved surfaces. If a part develops, the bag may be separated, or it may be discarded as a defective product due to an imbalance with a well-sealed area. Third, by manufacturing such a non-woven fabric bag separately, the process of ultrasonic fusion after cutting the margin part is added, thereby acting as a complicated and costly increase factor that adds the entire mask process, and fourth, a separate ultrasonic fusion facility for ultrasonic fusion of such a separate nonwoven fabric. Fifth, there is a problem that needs to be provided, and fifth, there is a problem of the inspection process and the manpower wasted according to the need for a separate inspection process to check the state of the non-woven fabric bag bonded during this process.

According to the present invention, in the process of manufacturing the mask having the filter replacement bag as described above, the nonwoven fabric, which is a fabric for the filter insert, is ultrasonically fused exactly three sides and the other one forms an unwelded opening during the general mask manufacturing process. It is an object to provide a method of manufacturing a mask having a filter bag for exchange.
The present invention also provides a mask manufacturing method in which a filter inserting bag having an opening for inserting the nonwoven fabric as described above is formed on the front member by adding the fabric supplying step for the pocket during the mask supplying and laminating step. Its purpose is.

A lower surface member supply part 30 is formed at one lower side of the main body 10, an upper surface member supply part 40 is formed at the lower center of the main body 10, and a product molding part 50 is formed at the upper side of the other side of the main body 10. Form each.

In the front member supply unit 20, a supply roller 21 and a laminated ultrasonic horn 23 are formed.

On the lower surface member supply part 30, the opposing lamination roller and the lamination ultrasonic horn 31 are formed, and the cutting roller 33 and the cutting ultrasonic horn are formed on one side thereof.

On the upper surface member supply part 40, the opposing lamination roller and the lamination ultrasonic horn 41 are formed, and the cutting roller 43 and the cutting ultrasonic horn are formed on one side thereof.

The product forming part 50 is formed by forming the opposite lamination roller and the lamination ultrasonic horn 51, and on one side thereof, the cutting roller 53 and the cutting ultrasonic horn are respectively formed to face each other (the specific description is made in Patent Registration No. 10). Reference is made to -0783311).

Through this general process, a mask (or also referred to as a folding mask) shown in FIG. 1B is provided. Such a mask does not have a filter insertion bag on the mask front side.

2A and 2B of the accompanying drawings are masks with a pocket formed by the manufacturing method of the present invention.

That is, the mask 1 consists of a front member 4, an upper surface member 5, and a lower surface member 6, and the upper portion of the bag 2 forms an opening 2a in the front member 4, , Are coupled to the both sides and the lower side by the ultrasonic welding portion (2b), and forms the earrings 7 on both sides of the mask body (1).

The mask manufacturing method of the present invention for manufacturing such a mask is largely as shown in Figures 3 and 4, the fabric supply step (S10), the fabric lamination step (S20), the ultrasonic welding step (S30), the margin part Cut step (S40), and the finishing step (S50) is made.

In other words,

That is, the first outer shell (not shown), the first filter member (not shown) and the first inner shell (not shown) are simultaneously supplied and laminated to form the front member 4, the second outer shell (not shown), and the second The filter member (not shown) and the second endothelial (not shown) are simultaneously supplied and laminated to form the lower surface member 6, the third jacket (not shown), the third filter member (not shown), the nose 51 and As the third shell (not shown), the upper surface member 5 is formed, and at the same time, the upper surface member 5 is supplied and laminated so that the fabric is supplied and laminated.

Alternatively, in another similar manner, the base fabric is provided by press-cutting the fabric to provide a front portion of the mask; an outer fabric that can be bonded to the base fabric to cover the outer edge of the base wand; A first side fabric that can be connected to the inner side upper edge of the base fabric to be folded in the inner surface direction, and can be connected to the lower edge of the inner surface of the base fabric to be folded in the inner surface direction of the base fabric Each of the second side fabrics may be laminated and supplied.

In particular, between the fabric supply step (S10) and the lamination step (S20) of the present invention is the first position (y) of the feed roller in which the front member supply unit 20 is located, the fabric for forming the bag (non-woven fabric) as shown in FIG. In the second position (x) to install a bag forming fabric supply roller 60 to widen the interval ("a") to the outside to feed and laminating the fabric for forming the bag. Of course, after the supply and lamination step is cut in a position that enters a predetermined width into the inside of the front member 4, the amount of cut of the bag fabric passing through the bag fabric feed roller 60 will be inevitably increased.

Third process: the ultrasonic welding step (S30),

The lower surface member and the upper surface member which have been cut are stacked on the upper surface of the front member so as to be positioned at an upper portion of the ultrasonic horn, and the front member, the lower surface member and the upper surface member are ultrasonically fused at the same time. Alternatively, the outer fabric, the base fabric, the first side fabric, and the second side fabric are laminated on the ultrasonic fusion jig and fused through an ultrasonic horn. (In this process, the cord is supplied and worn on both ends of the mask body. A step of attaching the string is included, but a detailed description thereof is well known as a general process, and thus will be omitted).

That is, the mask body is formed by ultrasonic welding and cutting in the state of lamination is completed, and when the ultrasonic welding is carried out as a c-shaped jig in a state in which the bag forming fabric is laminated on the mask body, the one side is opened and the three sides are The bonded mask front pocket will be formed.
