In particular, the bobbin 20 is a bar code 30 is stored in the outer periphery 21 is stored in a bar code 30 is stored in a multi-zone, divided into a multi-zone, the north chamber 40 is wound on the top of each bar code 30, and When the exhaust chamber 40 is exhausted, the detection unit 50 for detecting the light coming back after emitting light from the light emitting LED 51 to the barcode 30 and the barcode recognized by the detection unit 50 (30) characterized by consisting of a control unit 60 for analyzing the value compared to the set value, the speaker unit 71 and the light emitting lamp 72 to inform the operator when the exhaust chamber 40 is exhausted. do.

The bobbin 20 may be an 'H'-shaped or straight tube-shaped structure that winds up the drum 40, and in the case of the' H'-shaped bobbin, an additional partition may be formed for zoning and a small height in the case of the straight tubular The partition wall may be formed.

3 and 4, the bar code 30 is printed or displayed at one or both sides at a predetermined interval on the outer circumferential edge 21 of the bobbin 20, and the north chamber 40 wound around the bobbin 20. By detecting the bar code 30 is released by the detection unit 50 can be detected through the bar code 30 where the north chamber 40 is located on the outer periphery 21 of the bobbin 20.

The bar code 30 may be a bar code 30 representing a plurality of steps, rather than a general bar code including a code for notifying a start and an end. The barcode 30 may be printed and used in various forms such as wide and narrow bar lines or wide and narrow spaced patterns.

In the embodiment of the bar code 30, the bar code 30 simply divides the outer periphery 21 of the bobbin 20 into a plurality of zones, and is printed on the divided zones and the windings 40 wound on the divided zones 40. As the bar code 30 appears as the exhaustion of the present invention, the present invention is intended to detect the exhaust chamber 40 is exhausted by detecting the bar, the bar code 30 is a one-dimensional bar code or a two-dimensional bar code formed of a plane Can be used.

Meanwhile, the north room 40 is wound around the bobbin 20 divided into multi-zones due to the barcode 30, but as shown in FIG. 7, the zones 1, 41, 2, 42, and 3, each of which has the barcode 30 engraved therein. (43), after being divided into four sections (44) and continuously wound, the remaining drum 40 is wound in the fifth section (45), which is the entire upper portion not in contact with the outer periphery 21 of the bobbin (20).

In addition, the north chamber 40 is divided winding to the bobbin 20 through a split winding machine (not shown), the length of the north chamber 40 to be wound on the bobbin 30 in the split winding controller (not shown) Set to the desired length and wound, but when the drum 40 is wound around the bobbin 30 by the length set through the length measuring device (not shown), the lever (not shown) to move the drum 40 to the side ) Is continuously wound on the side by the desired length.

By way of example, in the split winding machine (not shown), the length of the yarn is 50 cm in the case of the first zone 41, and the length of the yarn is 20 cm in the second zone 42, and the three zones ( 43, the yarn thread length is 20 cm, the yarn length is 20 cm in the case of the 4 zone 44, the yarn thread length is 1800 cm in the case of the 5 zone 45, respectively. ) Will be wound on the bobbin (20).

For example, when the labeling (attachment sewing) work that takes 50 cm North room 40 using the bobbin 20 wound around the north room 40 as described above, 2 zones (5 to 45) Using the drum 40 wound up to 42), the first to 29th labeling operations are completed, and the barcode 40 wound up in the second chamber 42 during the 60th labeling operation is exhausted. The sensing unit 50 detects the light emitting lamp 72 or the speaker 71, and the operator recognizes this, and after completing the 30th labeling work, the bobbin 40 wound around the cabin 40 is replaced with the 31st job. Will be done. If the replacement was not completed after the 30th labeling operation, the northroom 40 was exhausted during the 31st labeling operation, which would cause a poor quality.

In this way, the north chamber 40 may be wound around the bobbin 20 in the outer circumferential edge 21 in various ways in consideration of the process length of the work and the amount of residue.

Meanwhile, the sensing unit 50 in which the light emitting LED 51 and the light receiving sensor 52 are formed to read the barcode 30 printed on the outer periphery 21 of the bobbin 20 so as to inform the operator by detecting the barcode 30. And converting the read barcode value 30 into a digital value using the decoder 61 and then operating the speaker 71 or the light emitting lamp 72 by comparing the preset value set by the setting unit 62. The control unit 60 is formed with a processing unit 63 for the processing, and the notification unit 70 is provided with a speaker 71 or a light emitting lamp 72 is driven according to the result of the processing unit 63.

The setting value is a value corresponding to a predetermined position of the outer circumferential edge 21 of the bobbin 20. When the worker has exhausted the north chamber 40 and the remaining amount of the north chamber 40 remains as desired, the setting unit 62 is set to the setting unit 62. The detection unit 50 function may be a value that is set in advance, or may be a value for warning the exhaustion of the residual amount when a specific barcode 30 value is read according to the reading of the barcode 30 of the detection unit 50 without presetting. Included as part of the.

According to the present invention, a method of detecting a north end point wound on a bobbin printed with a bar code of the present invention reads the bar code 30 value of the bobbin 20 on the outer circumferential edge 21 of which the north room 40 is released and exposed as shown in FIG. 8. Sensing step (S10); A conversion step (S20) of converting the barcode value into a digital value; A comparison step (S30) of comparing the digital value with a preset value at which a predetermined position of the bobbin 20 outer periphery 21 is input in advance; An expression step (S40) of expressing that the digital value corresponds to a set value; Determining an alarm time point by securing a trimming signal of the north chamber 40 through a trimming device (not shown) (S50); According to the trimming signal, the sewing machine is stopped or the display chamber S60 is displayed to indicate that the drum thread 40 has been trimmed by the speaker 71 or the light emitting lamp 72.

The following is a closer look.

The light of the light emitting LED 51 emitted toward the bobbin 20 exposed to the bobbin 40 by being released is reflected on the outer circumferential edge 21 of the bobbin 20 so that the light receiving sensor 52 receives the barcode 30 value. After the sensing step (S10) to read, the analog value of the barcode 30 thus read is amplified by an amplifier (not shown).

The amplified analog value is displayed as an accurate value in the conversion step (S20) which is converted into a digital value by the decoder 61 to inform the operator of the presence or absence of the north chamber 40 at the corresponding position of the outer periphery 21 of the bobbin 20. Inform.

That is, the digital value converted by reading the barcode 30 and the decoder 61 is transferred to the processing unit 63, and the processing unit 63 exchanges the setting value and the digital value which are preset values through the setting unit 62. Through the comparison step (S30) to compare with each other to determine whether the match. As a result of the determination, when the digital value and the set value match, the processing unit 63 expresses it to the notification unit 70 (S40).

When the sensing unit 50 detects the end point of the north room 40, the memory unit 63 stores the end point in the processing room 63. When the work is completed, the north room through the trimmer (not shown) cuts the thread by transmitting the end signal to the sewing machine. The trimming signal of 40 is secured to determine an alarm point (S50). Subsequently, a display step S60 of driving the speaker 71 or the light emitting lamp 72 that is the notification unit 70 according to the trimming signal of the trimming device is performed. The notification unit 70 is not limited to the speaker 71 or the light emitting lamp 72, there may be various embodiments such as LCD liquid crystal or LED display.

The operation of the alarm after the operation is that when the remaining amount of the north room 40 is secured enough to complete the current operation, that is, when the remaining amount of the amount required for the next operation does not remain, as shown in FIG. And by giving a replacement alarm in the room 40, the worker dared to care about the amount of residue in the room 40 during work, there is no reason to cause a psychological instability factor and vagueness that may occur after the room 40 is exhausted This can be prevented.

On the other hand, the operator can set in advance the notification time of the end of the north room 40 through the setting unit 62. That is, the operator can set the desired residue amount, the volume control of the alarm, the type of alarm (speaker or light emitting lamp) and the time of the alarm through the setting unit 62.

Here, the time of the alarm can be divided into working or after the operation, when operating the alarm during the operation of the alarm during the operation through the setting unit 62 to inform the worker that the predetermined amount of the north room 40 during the sewing operation remains. Set the time point, compare the digital value converted by reading the set value and the barcode 30 value of the outer periphery 21 of the bobbin 20 at the set alarm time point. The worker will be notified.

On the other hand, the barcode 30 is printed on a predetermined position on one side or both sides of the outer periphery 21 of the bobbin 20 has a value for expressing each position. Therefore, when the bar code 40 wound around the bobbin 20 is sequentially used to unwind from the 5 zone 45 to the 1 zone 41 during sewing, the notification unit 70 is opened when the barcode 30 is exposed to the outside. The operator will detect this.

As an example, when the position value for the alarm of the north end 40 of the bobbin 20 outer periphery 21 is set to three stages, the north chamber 40 wound around the bobbin 20 is the outer periphery of the bobbin 20 ( By being released from the outside of the 21, the bar code 30 indicating the respective positions from the bar code 30 printed on the outer periphery 21 of the bobbin 20 to the inside may be represented by 0 to 2.

That is, when the north chamber 40 wound around the outside of the bobbin 20 is released and the barcode 0 is exposed to the outside, the sensing unit 50 reads it and converts it into a digital value '00' through the decoder 61. The notification unit 70 is operated when it corresponds to the set value compared with a preset set value. In the same manner, the position 1 of the outer circumferential edge 21 of the bobbin 20 may be converted to a digital value of binary '01' and 2 may be converted to a digital value of binary '10'.

Here, the meanings of '00', '01', and '10' may be the same or different as the pattern of the barcode 30. The barcode 30 of the wide and narrow thickness means one or more configurations in a constant arrangement and is thick. The combination of thin lines can lead to a number of patterns.

This corresponds to the case where the detection position on the outer periphery 21 of the bobbin 20 for detecting the end point of the north room 40 is determined in three stages, but in addition, the end point of the north room 40 is configured by configuring a plurality of the detection locations. Can be implemented in multiple steps. In addition, each bar code 30 may be applied to a predetermined value rather than a sequential value as described above.

FIG. 6 is a north end point detecting device which is dividedly wound on a bobbin printed with a bar code according to another embodiment of the present invention, and the outside of the bobbin 10 as the position of the sensing unit 50 according to FIG. 5 is changed. By forming the through hole 14 of the size that can be inserted into the sensing unit 50 to the peripheral edge 13 and to fix the sensing unit 50 to recognize the barcode 30.

As described above, the present invention is divided by winding the bobbin thread printed on the bobbin outer periphery multi-zone, the detection unit sequentially reads the barcode appearing as the drum thread is used, and informs the worker to the worker due to the fugitive at sewing By connecting or sewing after connecting the defective and single yarn in advance, there is an effect of preventing the desealing defect and the cost increase due to reworking, productivity is improved.

In addition, the present invention is pre-divided winding as desired by the operator for the length of the drum room wound in each zone 50, 70, 100, 150cm, etc., and the remaining amount can be detected and predicted due to the barcode appearing every time the room exhausted This can increase the efficiency of the work.

In addition, the present invention is provided by the bobbin is divided into the bobbin in various lengths in each zone to the workshop can eliminate the hassle of sewing workers directly wound in the field can be more helpful to improve productivity.

The present invention is not limited to the preferred embodiments of the above features, and various modifications can be made by those skilled in the art without departing from the gist of the invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
