The bead supply means by the moving shaft and the rotating pulley coupled thereto does not support the bead exactly, but also does not supply the bead position accurately and uniformly. The play of the sewn beads is so large that it is inadequate to apply to products that are more luxurious.

In particular, the supply of beads in the supply of unstable or unstable supply is made because of this, the work is generated according to this, the supply process is not stable because the work speed is also lowered has a problem of falling productivity.

The present invention was devised to eliminate the problems as described above, the beads are sequentially supplied from the intermediate chamber in which the beads are threaded at regular intervals, the bead supply means to the supply pin and the blocking pin operated by the cylinder and the rotating shaft The supply pins and the blocking pins are crossed up and down by the operation of the cylinder, so that only a single bead is intermittently supplied by the supply pins as well as the position of the beads is accurately and consistently by the blocking pins. By keeping

It is possible to obtain a bead thread having a more uniform and balanced bead, as well as to prevent inaccurate supply or unsupply of the bead, thereby minimizing the defective rate. It is an object of the present invention to provide a bead supply device of a decorative bead yarn forming machine having a very economical feature to further improve the production speed of the yarn.

The one end of the connecting shaft 37 is hinged to the elevating hole 35 of the connecting table 36 to be elevated, and the other end of the connecting shaft 37 is hinged to the end of the rod 39 of the cylinder 38. ,

The blocking pin 33 and the supply pin 34 are elevated along the guide hole 40 on one side of the fixed block 31 by the operation of the cylinder 38, the blocking pin 33 and the supply pin 34 At the bottom of the) formed an inclined surface (42) on which the incision groove 41 and the beads (D) are seated, through which the intermediate chamber (C) can pass, respectively, the blocking pin (33) according to the operation of the cylinder (38). The beads (D) is to be supplied by the upward and downward sequential lifting of the supply pin (34).

Referring to the action of the bead supply device of the present invention decorative ballroom molding machine by the configuration as described above in more detail by the accompanying drawings as follows.

As shown in the drawing, the bead thread forming apparatus is manufactured by applying a conventional sewing apparatus, and the sewing machine of the upper side of the main body 100 that is operated by receiving power from the driving motor 102 built in the main body 100 ( The upper thread supply apparatus 10 is formed in 101, and one strand of upper thread A is supplied from the upper thread supply apparatus 10. As shown in FIG.

In addition, a lower bobbin supply device 20 for supplying two strands of the lower thread (B) (B ') is built in the lower facing surface of the upper thread supply device 10, the upper thread of the upper thread supply device 10 ( In connection with A) is to sew a variety of fabrics, etc., the lower thread (B) of the strand is entangled in a cross shape in connection with the upper thread (A), another lower thread (B ') is the upper thread (A) ) And the lower thread (B) are entangled in a zigzag pattern at the same time to form a node of the unit. The formation process of the knot by the weaving of the three strands is the same as that of the conventional overlock sewing machine, and is more specific. The description will be omitted.

When the intermediate thread supply device 30 according to the present invention is applied to such a conventional sewing device, the upper thread A and the intermediate thread C supplied by the intermediate thread supply device 30 are mediated. The lower thread (B) (B ') is intertwined with the middle thread (C) to complete a continuous twisted knotted thread, and the beads (D) inserted in the middle thread (C) are sequentially inserted in the respective knots. The intermittent supply is thereby completing a bead thread having a certain interval of beads.

Looking at the structure and operation relationship of the intermediate chamber supply device 30,

The cylinder 38 formed on the upper side of the sewing machine 101 is intermittently operated at preset intervals. As the rods 39 of the cylinder 38 emerge, separate beads D are individually supplied to each other. Decorative beads with beads are completed.

That is, the operation interval of the cylinder 38 is to set the supply interval of the beads, the shorter the operation time of the cylinder 38, the denser the interval of beads, the longer the operation interval is formed in proportion to the beads The gap is farther away.

Looking at the supply of such beads, when the rod 39 protrudes by the operation of the cylinder 38, the connecting shaft 37 of the end of the rod 39 is advanced, the connection of the connecting shaft 37 Rotating shaft 32 having a separate connecting table 36 is coupled to the end, so that when the connecting shaft 37 is operated, the rotating shaft 32 is rotated by an angle by receiving power from the connecting table 36.

At this time, since the long hole 35 is formed in the connecting table 36 of the rotating shaft 32 and the end of the connecting shaft 37 is hinged to the long hole 35, the front and rear of the connecting shaft 37 The rotating shaft 37 fixed in the sliding state is to be rotated by the operation of the connecting shaft 37, the connection coupled to the long hole 35 while maintaining the operating width of the cylinder 38 constant By adjusting the end position of the shaft 37, it is possible to adjust the rotation width of the rotary shaft 37.

As described above, the rotating shaft 32 performs forward and reverse rotation within a predetermined angle according to the operation of the cylinder 38. An end of the rotating shaft 32 has a separate blocking pin 33 coupled downwardly so that the front end thereof is movable. ) And the supply pin 34 is hinged,

The rotary shaft 32 is inserted in the middle of the blocking pin 33 and the supply pin 34 is inserted into the guide hole 40 protruding toward one side of the fixed block 31 for fixing the rotary shaft 32. When the forward and reverse rotation, the blocking pin 33 and the supply pin 34 interlock to move up and down.

At this time, the ends of the blocking plate 33 and the supply pins 34 are spaced apart from each other and the lower ends thereof are installed in close proximity to each other. By the configuration of the blocking pin 33 and the supply pin 34 spaced apart from each other they are sequentially lifted up and down alternately with each other.

That is, in the forward rotation of the rotary shaft 32, the supply pin 34 is lowered and the blocking pin 33 is raised as shown in FIG. 4A, and the rotary shaft 32 is reversed as shown in FIG. 4B. When rotated, the supply pin 34 is raised while the blocking pin 33 is lowered.

In addition, a cutout groove 41 is formed at the lower end of the blocking pin 33 and the supply pin 34 as described above, and the cutaway groove 41 allows the intermediate chamber C to pass therethrough. ) And the well-known upper thread (A) and the lower thread (B) by the normal operation of the sewing machine 101 at one side of the blocking pin 33, each yarn is tangled with each other to form a continuous chain knot.

Looking at the operation structure that the beads (D) are sequentially supplied by the operation of the blocking pin 33 and the supply pin 34, the beads (D) is continuously inserted into the intermediate chamber (C) as the state Bead (D) located at the top end is in contact with one surface of the supply pin (34).

At this time, one side of the supply pin 34 is formed with an inclined surface 42 which allows one side of the bead (D) to be stably mounted, so the bead (D) at the uppermost end is placed on the inclined surface (42). It will be in close contact.

In this state, when the supply pin 34 is raised by the operation of the cylinder 38 and the rotation of the rotary shaft 32, the most bead (D) is located on one side of the blocking pin 33 which is lowered. The blocking pin 33 and the supply pin 34 has the upper and lower lifting widths slightly larger than the diameter of the beads, and the lifting speed is also relatively fast so that the beads (D) are the same. There is no possibility of overrunning past the blocking pin 33.

Therefore, the supply pin 34, which has been raised as described above, comes into close contact with one side of the blocking pin 33 and descends between the beads D and the beads located at the rear side thereof, and the beads D at the uppermost level are blocked pins ( The ball is pushed toward 33, and the beads on the rear side are in a standby state located on the inclined surface 42 of the supply pin 34 again.

Here, the beads (D) located on one side of the blocking pin 33 by the falling of the supply pin 34 is pushed toward the blocking pin 33, the blocking pin 33 is an electrical supply pin ( Since the act of ascending and descending at the same time as 34), the beads (D) is smoothly moved through the blocking pin 33 to the knot part to complete a single knot with beads.

When the knot with the beads is completed as described above, the cylinder 38 is not operated during several knots thereafter, so that the supply of the beads is suppressed. When the knot is completed, the cylinder 38 is operated again. It is possible to produce a bead thread in which beads (D) are woven at a predetermined interval by supplying a bead at high speed.

Therefore, since only one bead is stably supplied as described above, the upper thread (A) and the lower thread (B), the middle provided from the upper thread supply device 10 and the lower thread supply device 20 and the intermediate thread supply device 30, respectively. The thread (C) is tangled with each other to create a knot with beads as well as a continuous thread with no knots.

At this time, the knot is continuously formed by the sewing machine 101, which is a reference for setting the interval of the beads (D), the operation interval of the cylinder 38 through the interval by the number of knots By adjusting the bead (D) to vary the interval of the ball will be able to conveniently produce a ballroom having a variety of beads spacing.

The bead supply device of the decorative bead yarn forming machine as described above can obtain a bead thread having beads of a more uniform and balanced position, and can also prevent inaccurate supply or unsupply of beads, thereby minimizing the defective rate. By the accurate and constant supply of beads, the production speed of the yarn can be further improved, which is very economical.
