Referring to FIG.

Referring to FIG. 1, a yarn feeding device for adjusting a glass gap according to an exemplary embodiment of the present invention may include an yarn feeder 100, a main body 200, and an air injector 300.

Specifically, the yarn feeder 100 may include a failure 110 and a failure mount 120.

Failure 110 may be configured to mount the seal. To this end, the failure 110 may be in the form of two circular disc plates coupled to both ends of the cylindrical roll. The yarn for adjusting the glass clearance can be wound around the cylindrical rotator constituting the failure 110. Here, the failure 110 may be formed so as to penetrate through the center in a circular shape so as to be mounted on the failure receptacle 120.

For this purpose, the failing cradle 120 may be formed with a plate support portion so as to be abutted against the ground or fixed to one surface thereof, and a mounting portion for mounting the failure can be protruded from the support portion. The shape of the mounting part is not limited, and the shape for the failure is sufficient.

For example, the mounting portion may be formed from a vertical plate perpendicular to the base portion and a projection corresponding to a circular tube projecting to one side from the vertical plate and passing through the center of the failure.

The main body 200 can transfer the yarn supplied from the yarn supply unit.

2, the main body 200 may include a body 210, a tension portion 220, and a roller portion 230.

The shape of the body 210 is not limited, and a structure in which the tension part 220 and the roller part 230 can be installed at the upper end is sufficient.

The tension unit 220 may be fixed to the upper end of the body 210. Further, the tension portion 220 can form the tensile force of the yarn fed from the yarn feeder 100. For this purpose, it is preferable that the tension unit 220 is positioned higher than the thread supply unit 100. In other words, a height difference may be provided between the yarn supplying unit 100 and the tension unit 220, so that the yarn can be formed to be taut.

On the other hand, the tension part 220 may be formed to rotate in accordance with the movement of the yarn since the yarn must pass while forming the tension. 3, the tension unit 220 is formed with two support brackets 222 fixed to the upper end of the body 210 and has a rotation shaft 224 connected between the support brackets 222 And a disk roller 226 coupled to the rotating shaft 224 and rotated.

The yarn running over the disk roller 226 is tensioned by the difference in height from the yarn feeder 100, and the disk roller 226 can be rotated and transported easily when being transported forward.

The roller portion 230 can roll the yarn and feed it. For this purpose, the roller unit 230 may be installed in front of the tension unit 220 so as to be fixed to the upper end of the body. In addition, the roller unit 230 may include at least three rollers 232. This is because the three rollers 232 as the minimum number of rollers for feeding the yarn can be formed in a triangular arrangement.

Specifically, a motor can be connected to one of the two rollers arranged on the lower side. Here, the motor may be a servo motor 234, which is mounted to move the thread to a constant distance value. That is, the yarn feeder for controlling the gap of the glass according to the embodiment of the present invention includes the servo motor 234, so that the yarn feeder 100 is moved from the yarn feeder 100 to the air injector 300, There may be almost no deviation.

Further, one roller 232 arranged on the upper side can be formed to press the yarn. In order to maintain the tensile force of the tensioned yarn in the tension unit 220, the roller 232 arranged on the upper side is configured to be conveyed upward and downward to adjust the pressing force.

A chain 244 is mounted between the sprockets 242 to connect the sprocket 242. Thus, the roller 232 can be prevented from slipping upon rotation, and the number of revolutions of the roller 232 controlled by the servo motor 234 can be accurately maintained.

Meanwhile, although not shown in the drawing, the chain portion 240 may further include a chain portion housing (not shown) for safety of workers and protection of components.

Hereinafter, the air injector unit 300 will be described with reference to FIG.

The air injector part 300 may be formed so that the chamber transferred from the main body part 200 falls vertically and uniformly. This is because, in order to adjust the gap between the glasses, the yarn must be accurately placed between the glasses, and the yarn is easily affected by the wind or temperature outside due to its light characteristics.

Further, when the yarn is dropped, there is room for the yarn to rotate and twist without a certain pressure.

For this reason, it is possible to vertically drop the yarn instantaneously vertically by using the air injector unit 300 using air pressure, so that the yarn can be accurately supplied to one side of the glass without twisting the yarn.

More specifically, the air injector unit 300 may include a fixing bracket 310, a first guide pin 320, and an injector 330 for the above-described operation.

The fixing bracket 310 is for fixing a part of the air injector part 300 and may be fixed to the front surface of the body. That is, a part of the air injector unit 300 may be formed on the entire surface of the body, preferably on the lower surface of the body.

The first guide pin 320 may be fixed to the upper portion of the fixing bracket 310. Further, the first guide pin 320 can guide the angle of the thread transferred from the main body 200 to be deformed. At this time, it is preferable that the first guide pin 320 is deformed so as to form a vertical length so that the transported yarn falls vertically. For this purpose, the first guide pin 320 may be fixed perpendicularly to the fixing bracket 310.

The injector 330 may be fixed to a lower portion of the fixing bracket 310. This is to be formed below the first guide pin 320, and the thread vertically guided from the first guide pin 320 can be transmitted to the injector 330. In addition, the injector 330 can be connected to the air supply part 340 to vertically drop the air-transferred yarn without kinking. Here, the air supply unit 340 may include an air compressor (not shown) and an air regulator 344.

An air compressor (not shown) compresses air to supply air to the injector 330, and is connected to the injector 330 by an air hose to supply the compressed air to the injector 330. At this time, an air regulator 344 is provided at one side of the air hose to adjust the pressure of the air supplied to the injector 330.

The injector 330 can supply the air by the air supply unit 340 and drop the air by the air pressure, thereby positioning the seal on one side of the glass.

Meanwhile, the injector 330 may be fixed when installed, but not limited thereto, and may be formed so that its position can be adjusted up / down and left / right. To this end, a vertical bar 350 is formed on the front surface of the body 210 to form a length in the vertical direction, and a first horizontal bar 360 is formed on the vertical bar 350 to form a length in the horizontal direction .

A first guide groove 352 may be formed along the longitudinal direction at the front end of the vertical bar 350. A second guide groove 362 may be formed at the front end of the first horizontal bar 360 along the longitudinal direction. . At this time, the first horizontal bar 360 may be coupled to the first guide groove 352 to be movable up and down.

The fixing bracket 310 may be coupled to the second guide groove 362 of the first horizontal bar 360. That is, the fixing bracket 310 is formed to be transferred to the left and right along the second guide groove 362, and the first horizontal bar 360 coupled with the fixing bracket 310 is connected to the first guide 350 of the vertical bar 350, The injector 330 connected to the fixing bracket 310 can also be adjusted in the up / down and left / right directions by moving upward / downward along the groove 352. This has the advantage of controlling the position and spacing of the injector according to the size of the glass.

Meanwhile, the yarn supply device for controlling the gap of the glass according to the embodiment of the present invention may further include three guide pins for guiding the yarn more tightly and facilitating tension and angular deformation of the yarn. This will be described with reference to FIG.

5 is a view showing the addition of second to fourth guide portions to the yarn feeding device for adjusting the glass gap according to the embodiment of the present invention.

Referring to FIG. 5, the second guide pin 400, which is one of the three guide pins, may be installed in the thread supply unit 100. Specifically, the second guide pin 400 may be formed in front of the failure 110 and the failing cradle 120. When the yarn supplying unit 100 is formed far from the main body 200, the yarn may be stuck and tension of the yarn may not be formed by the tension unit 220 alone. Therefore, the second guide pin 400 may be provided to assist .

Here, the second guide pin 400 may stand upright or form a predetermined angle.

Further, in the case of the second guide pin 400, the position of the second guide pin 400 may be adjusted to the left or right as in the case of the injector 330.

At this time, the position adjustment method may be the same as that of the injector 330. The second guide pin 400 may be fixed to the coupling plate 410. The coupling plate 410 may include a second horizontal bar 420 having a third guide groove 422 formed along the length thereof, Lt; / RTI >

Since the coupling plate 410 is formed to be transferred along the third guide groove 422, the position of the second guide pin 400 connected to the coupling plate 410 can be adjusted.

The third guide pin 500, which is another one of the three guide pins, may be formed between the thread supply part 100 and the body part 200. The third guide pin 500 may be provided adjacent to the tension unit 220 because the thread guide 100 may be provided with the second guide pin 400. [

That is, the gap between the body portion 200 and the thread supply portion 100 is reduced through the second guide pin 400 provided in the thread supply portion 100 and the third guide pin 500 provided adjacent to the tension portion 220 The tension can be more easily formed even at a distance, and can be formed so that the yarn can be easily conveyed.

Further, the third guide pin 500 may be erected or formed at a predetermined angle.

On the other hand, when the second guide pin 400 is not provided, the third guide pin 500 may be formed on the center side between the thread supply part 100 and the main body 200.

The fourth guide pin 600 of the three guide pins may be formed between the main body 200 and the air injector 300. Here, the fourth guide pin 600 may be formed to have an upright or predetermined angle, which can guide the thread to the air injector part 300 easily.

That is, the yarn drawn into the air injector unit 300 from the main body 200 can be vertically drawn through the fourth and first guide pins 600 and 320 sequentially.

Although three guide pins 400, 500, and 600 may be further added in the above description, the guide pins are limited to facilitate understanding, and different guide pins may be provided depending on the length of the yarn feeder, It is of course possible to additionally be practiced.

The yarn supply device for adjusting the glass gap according to the embodiment of the present invention configured as described above can ensure that the yarns are accurately positioned on one side of the glass so that the gap between the glasses can be formed.

Meanwhile, the yarn feeding device for controlling the gap of the glass according to the embodiment of the present invention can be formed so that not only yarn feeding but also yarn returning can be performed between the glasses.

This can be done not simply by changing the shape or changing the structure, but simply by installing a recovery motor in the yarn supply unit 100.

Specifically, referring to FIG. 5, a recovery motor may be installed in the failure 110 for the recovery operation. At this time, the recovery motor 700 may be formed to be reversely rotated, and preferably both the forward and reverse rotations can be performed. Accordingly, the recovery motor 700 installed in the failure and the servo motor 234 installed in the roller unit 230 are reversely rotated to recover the yarn supplied between the glasses.

Here, the main body 200 may include a sensor unit (not shown) capable of detecting movement of the thread. This is because the recovery operation may not be performed when the yarn is recovered when the yarn is recovered or when the yarn is twisted. To detect this, the sensor unit (not shown) Can be formed.

However, the present invention is not limited to this, and the sensing operation may be performed by sensing the rotational movement of the roller 232 or the failure 110.

Although the number of yarns to be fed is not limited to one, the number of yarn feeds may not be limited to one, but may include a failure 110, first to fourth guide units 320, 400, 500 and 600, (330) or the like may be formed in a number corresponding to the number of two or more, or four or more.

In the above description, the yarn feeder is fixedly installed on one side and operated. However, the yarn feeder for adjusting the gap according to the embodiment of the present invention may be mounted on the robot. At this time, the body 210 may form a plurality of lightweight adjusting holes (not shown) or lightweight adjusting grooves (not shown) for weight reduction.

In the above description, the yarn supplying unit 100 is illustrated as being two-dimensionally separated from the main body 200 as shown in FIG. 6. However, the yarn supplying unit 100 is not limited to the example shown in FIG. 100 may be formed so as to be unified with the main body 200. That is, the position of the yarn supplying unit 100 is not limited.

Hereinafter, with reference to FIGS. 6 to 8, a method of adjusting the glass interval through the yarn supplying device for adjusting the glass interval will be briefly described.

FIG. 6 is a view showing an example of feeding a yarn feeder for adjusting a glass gap according to an embodiment of the present invention, FIG. 7 is an example of yarn feeding in which the yarn feeder of FIG. Is an example of a method of controlling the glass interval through a yarn supply device for adjusting the glass interval.

6 to 7, the yarn T may be supplied through the yarn feeder 100, the main body 200, and the air injector 300 of the yarn feeder for adjusting the gap of the glass .

Also, the thread T supplied through the thread supply device for adjusting the gap of the glass formed on the upper side of the glass mounting part can be fixed to the glass mounting part by being lowered by a predetermined amount. At this time, one glass (G) is loaded in the forward direction of the fixed room.

When one glass (G) is loaded, the thread (T) is lowered by a certain amount. At this time, the lowered thread T is lowered to the front of the loaded glass G, the thread T is positioned along the rear, upper, and front sides of the glass G, (T) is stretched.

Thereafter, by repeating the loading of the glass (G) and the descending of the thread (T), the interval between the glasses can be adjusted as shown in Fig.
