Hereinafter, the shape of the incoming direction guide gear 240 according to the first embodiment of the present invention will be described in more detail with reference to FIG.

First, in a ribbon sealing machine 100 capable of eating a long meals according to an embodiment of the present invention, a needle embroidery pattern is formed on a fabric 10 by a reciprocating motion of a needle 262 to which an embroidery thread is coupled, A plurality of ribbon guide holes arranged corresponding to the needles 262 between the fabric 10 and the needles 262 for guiding the drawing direction of the ribbon to be sealed to the fabric 10, A controller for controlling the driving direction of the incoming direction guide gear so that the direction of insertion of the ribbon corresponds to the advancing direction of the embroidery pattern; And a power transmitting member 206 which moves left and right by a control signal of the controller and engages with the incoming direction guide gear 240. At this time, the incoming direction guide gear 240 is connected to the power transmitting member 206 A radial gear 241 is formed on the outer circumferential surface so as to be interlocked with the needle hole 242 and a needle hole 242 through which the needle 262 passes is formed in the shaft center 290, A first ribbon guide hole 243a and a second ribbon guide hole 243b are formed between the first ribbon guide hole 243a and the second ribbon guide hole 243b. 290 adjacent to each other asymmetrically. At this time, the first ribbon guide hole 243a and the second ribbon guide hole 243b may be formed as a left-right pair with respect to the shaft center 290, and the relatively wide ribbon 20 may be inserted into the needle 262, In the direction of the reciprocating motion path.

The infeed direction guide gear 240 includes a pair of left and right third ribbon guide holes 243c for guiding the relatively narrow ribbon 21 in the reciprocating path direction of the needle 262, The third ribbon guide hole 243c may include a first ribbon guide hole 243a and a fourth ribbon guide hole 243d. The third ribbon guide hole 243d may be formed asymmetrically adjacent to the shaft center 290, The second ribbon guide hole 243b and the second ribbon guide hole 243b.

That is, at the adjacent positions of the first ribbon guide hole 243a or the second ribbon guide hole 243b, at least one ribbon guide hole (that is, The third ribbon guide hole 243c or the fourth ribbon guide hole 243d) may be formed in parallel.

Each of the first to fourth ribbon guide holes 243a, 243b, 243c and 243d is formed in a slit shape and is inserted into the first ribbon guide hole 243a and the second ribbon guide hole 243b It is preferable that the width of the wide ribbon 20 is formed to be wider than the width of the narrow ribbon 21 to be drawn into the third ribbon guide hole 243c and the fourth ribbon guide hole 243d.

The infeed direction guide gear 240 includes a first ribbon guide hole 243a and a second ribbon guide hole 243b or a third ribbon guide hole 243c and a fourth ribbon guide hole 243d, May be formed so as to be positioned within 180 degrees with respect to the base plate 290.

 Preferably, the first ribbon guide hole 243a and the second ribbon guide hole 243b in the lead-in direction guide gear 240 of the present invention form an angle of less than 180 degrees with respect to the axial center 290, As shown in FIG. In this case, the term asymmetry means that the first ribbon guide hole 243a and the second ribbon guide hole 243b form an angle of 180 degrees with respect to the axis of the shaft and do not form a symmetry, As shown in FIG. Also, the third ribbon guide hole 243c and the fourth ribbon guide hole 243d may be formed asymmetrically with each other, forming an angle of less than 180 degrees with respect to the shaft center 290.

In addition, the first ribbon guide hole 243a and the second ribbon guide hole 243b can supply ribbons having different widths or shapes, respectively. 3 to 5, if the first ribbon guide hole 243a and the second ribbon guide hole 243b are symmetrically disposed at 180 ° with respect to the shaft center 290, There is a problem that the stroke length of the power transmitting member 206 becomes long because the inlet direction guide gear 240 needs to be rotated by 180 ° when the first ribbon is sewn to the second ribbon, . If the stroke length becomes long, the range of motion of the embroidery frame becomes narrow and the design can not cope with a large design.

In the present invention, the first ribbon guide hole 243a and the second ribbon guide hole 243b are disposed asymmetrically with respect to the shaft center 290 at an angle of less than 180 ° as shown in FIGS. 3 to 5 The time can be shortened when the first ribbon is sealed and then changed to the second ribbon, which is advantageous in coping with high-speed operation.

Each of the plurality of decorative punctures 243e and 243f to be described later is provided at a position not overlapping with the first ribbon guide hole 243a and the second ribbon guide hole 243b, And is disposed at an acute angle smaller than 90 DEG with respect to the center line 242. Since the angle between the decorative thread hole 243e and the decorative thread hole 243f is also relatively small, the stroke length of the power transmitting member 206 can be reduced when changing the seat meal to be sealed.

That is, the present invention provides a ribbon sealing machine for a ribbon sealing machine which is capable of sealing a plurality of types of ribbons having a size or shape without changing the apparatuses in one embroidery, a power transmitting member 206 can be reduced. This can shorten the time required for changing the ribbon or decorative yarn, and is advantageous in coping with high-speed operation.

5, the second ribbon guide hole 243b and the fourth ribbon guide hole 243d of the present invention are inserted into the needle hole 242 (see FIG. 5) ) In a direction parallel to the substrate. The first ribbon guide hole 243a and the third ribbon guide hole 243c are also formed in a structure parallel to the needle hole 242. [ In addition, in the side sectional view (A-A '), the decorative hole 243e is formed on the upper side of the eye 242.

Not only a single ribbon embroidery is possible through each ribbon guide hole, but also on the left side of the shaft center 290, based on the four ribbon guide holes 243a, 243b, 243c and 243d which are preferably formed. A two-layer ribbon embroidery having a two-layer structure is formed by using the first or third ribbon guide holes 243a and 243c or the second or fourth ribbon guide holes 243b and 243d formed on the right side of the shaft center 290 There is an advantage that it is possible. That is, the present invention allows double ribbon embroidery with two ribbons of different widths, as well as one ribbon embroidery (i.e., a single ribbon embroidery).

Although the first ribbon guide hole 243a and the second ribbon guide hole 243b of the lead-in direction guide gear 240 according to the first embodiment described above may have different widths or shapes, Only one embodiment can guide the ribbons having the same width. In another embodiment, the first to fourth ribbon guide holes 243a, 243b, 243c, and 243d may guide ribbons having the same width.

The insertion direction guide gear 240 is formed at a position where it does not interfere with the first to fourth ribbon guide holes 243a, 243b, 243c, and 243d, And a plurality of decorative pores 243e and 243f for guiding the decorative pores 243e and 243f. At this time, the plurality of decorative pores 243e and 243f are holes for embroidery (or chord) embroidery, and may have different sizes, and in other embodiments, they may have the same size. The first ornamental hole 243e and the second ornamental hole 243f in the plurality of ornamental holes 243e and 243f may be formed to be located at an acute angle within 90 ° around the needle hole 242, , For example, 60 [deg.].

The insertion direction guide gear 240 has a concave portion 244 formed at one side facing the fabric 10 and partially recessed around the needle hole 242 (or with respect to the axial center 290) And the present invention has the following advantages through the concave portion 244.

The concave portion 244 is provided to provide a space between the needle hole 242 and the fabric 10. If there is no concave portion 244, the gap between the needle hole 242 and the fabric 10 is only about 3 mm, During the weaving operation, the interval becomes narrower. At this time, the present invention is a technique that allows a long-time meal embroidery and ribbon embroidery with a single sealing machine, and there is a difference in thickness / thickness between the decorative yarn and the ribbon (for example, the thickness of the decorative yarn may be larger than the thickness of the ribbon If one side of the needle hole 242 facing the fabric 10 without the recess 244 takes a flat shape, when an unwanted knot is formed by the rotation of the decorative yarn during the weaving operation, It may not be enough to cause undesired phenomena such as twisted embroidery patterns. Accordingly, the concave portion 244 of the present invention is formed in consideration of the difference in thickness / thickness between the decorative yarn and the ribbon, and to provide a space for releasing the twisted embroidery pattern at the time of embroidery. In addition, the present invention increases the degree of freedom of the path through which the ribbon is drawn in the outlets of the first to fourth ribbon guide holes 243a, 243b, 243c, and 243d due to the shape of the concave portion 244, There is an effect that the movement can be easily controlled.
