2 and 3, the mask band knitting apparatus according to the present invention guides the yarn supply member 10 for supplying the yarn for forming the mask band, and the yarn supplied from the yarn supply member 10. A yarn guide member 20 for knitting the yarn; a knitting member 30 for knitting the yarn supplied through the yarn guide member 20; a rotating member 40 for rotating the knitting member 30; It includes a pressing member 50 for pressing the band knitted by the knitting member 30, wherein the pressing member 50 includes a pair of rollers 52 and 54 disposed to face each other, and the pair of rollers One of the rollers 52 and 54 is formed of a metal roller 52, the other roller 54 is formed of a synthetic resin roller, and any one of the pair of rollers 52 and 54 has the roller It is characterized in that the spacer member 60 for spacing the band attached to the surface (52, 54) is disposed.

The thread supply member 10 is composed of spools 10-1 and 10-2 for supplying a thread for forming a band for a mask.

Since two types of threads are usually supplied to form a band for a mask, the thread supply member 10 includes two spools 10 - 1 and 10 - 2 .

For example, a very elastic thread is wound on the first spool 10-1, and a thread with low elasticity is wound on the second spool 10-2. It may be configured to be supplied to the knitting member 30 in a wound state .

Thus, by knitting two yarns 2-1 and 2-2 having different elasticity through the knitting member 30, a band for a mask can be formed.

The yarn supplied by the yarn supply member 10 is guided to the knitting member 30 by the yarn guide member 20 .

The yarn guide member 20 is the knitting member while the yarns 2-1 and 2-2 released from the two spools 10-1 and 10-2 disposed at different positions do not become entangled with each other. (30) is configured to be supplied.

The yarns 2-1 and 2-2 supplied through the yarn guide member 20 are knitted into the band 2 by the knitting member 30 .

The knitting member 30 is configured to be rotated by the rotating member 40 in a state formed in a substantially frusto-conical shape.

On the outer surface of the knitting member 30, grooves 32 are formed at predetermined intervals in the vertical direction, and the knitting needles 34 are vertically arranged in the grooves 32 .

In this state, as the knitting member 30 is rotated by the rotating member 40, the knitting needles 34 are sequentially lifted up and down in the vertical direction.

Accordingly, the yarns 2-1 and 2-2 are knitted in the form of a band having a circular cross section while the knitting needles 34 are lifted and rotated.

Although, in FIG. 4 , the knitting needles 34 are shown to be included in two, this is for understanding through the illustration and may be installed in various numbers such as three to five in reality.

The band 2 knitted by the knitting member 30 is dropped downward through the central space of the knitting member 30, preventing loosening of the knitted yarns 2-1 and 2-2 and forming a flat shape It is compressed by the pressing member 50 for this purpose.

The compression member 50 includes a pair of rollers 52 and 54 disposed opposite to each other to squeeze the band 2 knitted by the knitting member 30 .

Among the pair of rollers 52 and 54, the lower roller 52 is formed of a metal material such as stainless steel, and the upper roller 54 is formed of synthetic resin rubber.

Thus, by strongly pressing the lower roller 52 made of metal and the upper roller 54 made of synthetic resin rubber, the band 2 can be flattened.

In the band knitting apparatus for a mask according to the present invention, as shown in FIG. 5 , a band 2 compressed by the two rollers 52 and 54 is applied to the roller 52 disposed below the two rollers. A spacer member (60) for spaced apart from the surface of the (52, 54) is disposed.

The spacer member 60 is formed of a synthetic resin material such as elastic vinyl having a thickness of about 0.2 to 1 mm in a rectangular shape, and is disposed around the lower roller 52 in the circumferential direction.

And, one end 62 of the spacer member 60 is attached to the lower roller 52, the other end is not attached to a kind of free end state.

In this state, when the lower roller 52 is rotated clockwise as shown in FIG. 7 , the other end that is not attached is dropped by its own weight, and the knitted band 2 is moved to the lower roller 52 . It strikes outward from the surface.

Thus, whenever the lower roller 52 rotates once, the spacer 60 strikes the band 2 to the outside, thereby preventing the band 2 from being entangled with the surface of the lower roller 52 . have.

In another embodiment of the present invention shown in Figure 6, the spacer member 60 is formed of two sheets of elastic synthetic resin vinyl.

Thus, when the lower roller 52 rotates, the two sheets of synthetic resin vinyl are dropped by their own weight, thereby making it possible to more reliably separate the band 2 from the surface of the lower roller 52 .

Although the spacer member 60 is exemplified by synthetic resin vinyl in the above embodiment, it is not limited thereto and may be formed of various elastic synthetic resin materials.

For example, it may be formed of a very thin polyethylene resin or polypropylene resin.

In another embodiment of the present invention shown in FIG. 8 , a concave portion 64 along the longitudinal direction is formed on the surface of the spacer 60 .

In a state in which the concave portion 64 is formed in the spacer 60 as described above, the concave portion 64 is disposed along the circumferential direction of the lower metal roller 52 .

By reducing the contact area between the band 2 and the surface of the spacer 60 by the concave portion 64, it is possible to prevent the band 2 from sticking to the surface of the spacer 60 when pressing the band.

And, in the cross section of the concave portion 64, the side wall edge portion acts as a frictional force on the band 2, so that the band 2 moves in the width direction of the spacer 60 (the axial direction of the lower roller) can be prevented from becoming

As a method for forming the concave portion 64 , it may be formed by attaching synthetic resin tapes at predetermined intervals along the longitudinal direction to the surface of the spacer 60 formed of a synthetic resin material.

Thus, the portion between adjacent synthetic resin tapes can serve as the concave portion 64 .

As described above, in order to prevent the band 2 from sticking to the roller surface or moving in the axial direction of the roller, as shown in FIG. 9, in another embodiment of the present invention, the upper synthetic resin roller ( A concave portion 544 and a convex portion 546 may be formed on the surface of the 54 in the circumferential direction.

The concave portion 544 and the convex portion 546 are very finely formed on the surface of the upper roller 54, for example, the height difference between the concave portion 544 and the convex portion 546 is approximately 0.1 to It is formed in the range of 0.2 mm.

As described above, by the concave portion 64 on the surface of the spacer 60 and the concave portion 544 and the convex portion 546 on the surface of the upper roller 54, the band 2 is prevented from sticking to the roller surface. However, it is possible to prevent the upper roller 54 from being moved in the axial direction and separated.

On the other hand, as shown in FIG. 10 , the upper synthetic resin roller 54 is detachably coupled to the roller detachable member 70 .

That is, the upper roller 54 is disposed to contact the lower metal roller 52 while its shaft 542 is mounted on the roller attaching and detaching member 70, and By this, the upper roller 54 is rotated passively.

Roller shaft arrangement concave portions 72 and 74 for accommodating the roller shaft 542 of the upper roller 54 are formed in the roller attaching and detaching member 70 .

A pair of the roller shaft arrangement concave portions 72 and 74 may be formed at different positions in the roller attaching and detaching member 70 .

In addition, the roller shaft arrangement recesses (72, 74) may be formed in a "L" shape.

Thus, the upper roller 54 is first moved downward along the roller shaft arrangement recesses 72 and 74, and then moved in the horizontal direction so that the roller shaft 542 becomes the roller shaft arrangement recesses 72 and 74. It can be coupled to the tip space (722, 742) of the.

As described above, since the roller shaft arrangement recesses 72 and 74 are formed in a “L” shape, even when strongly compressed with the lower roller 52 , the upper roller 54 may flow or the roller attaching and detaching member 70 . can be prevented from escaping.

And, as described above, by forming a pair of the roller shaft arranging recesses 72 and 74 at different positions, the upper rollers 54 disposed adjacent to each other alternately the front roller shaft arranging recesses 72 and the rear rollers It may be coupled to the shaft arrangement concave portion (74).

Thus, the upper roller 54 disposed adjacent to each other and the band 2 passing therethrough may be moved as far as possible from each other.

Thereby, it is possible to prevent the bands 2 moving adjacently from being tangled with each other.

Meanwhile, as shown in FIGS. 2 and 13 , a rotating member 80 for rotating the band 2 may be installed under the pair of rollers 52 and 54 .

The rotating member 80 is made of a synthetic resin material and is formed in a hollow cylinder shape, and in order to reduce the contact area and frictional force with the band 2, concave portions 82 and convex portions 84 are formed on the inner surface of the rotating member. can be

In the process of compressing the band 2 by the upper roller 54 and the lower roller 52, in reality, the band 2 reciprocates to some extent in the horizontal direction along the axial direction of the rollers 52 and 54. is moved

As described above, the distance (amplitude) reciprocated in the horizontal direction varies from moment to moment. In the portion where the upper and lower rollers 52 and 54 abut, the band 2 moves horizontally, but when it descends to the location of the collection box 90 In reality, the pendulum moves irregularly.

If there is no rotation member 80, the band 2 is cluttered up in the collection box 90 by the irregular pendulum movement as described above. In this case, the collection box 90 before the next process proceeds. After untiing the bands (2) piled up in a line in a row, you need to arrange them in a circle again.

However, if the rotating member 80 having a smaller diameter than the diameter of the irregular pendulum motion of the band 2 is disposed at a position where the band 2 is freely falling as described above, the band 2 is rotated It was discovered that the member 80 rotates in one direction while contacting the inner surface.

Due to this phenomenon, the band 2 is stacked while being rotated in one direction inside the collection box 90 , and the band inside the collection box 90 can be immediately supplied as a post-processing device for cutting and the like.

This is because the bands in the collection box 90 are stacked in a state that can be released in one direction.

14 is a rotating member 80 according to another embodiment of the present invention, wherein the rotating member 80 is formed of a metal material, and a coil portion 86 may be formed in a portion in contact with the band.

Thus, by allowing the band 2 to pass into the coil unit 86 , it is possible to rotate the band in one direction through the coil unit 86 during pendulum movement of the band.
