In describing an example of the present invention, drawings and descriptions of well-known technical contents that are not directly related to the present invention are omitted, and thus the present invention is clearly communicated without obscuring the gist of the present invention.

Referring to Figure 4, when explaining the cord yarn supply control device of the embroidery machine by one example of the present invention, the pattern portion 110; Control unit 120; Arithmetic unit 140; Input unit 150; And a motor 130.

The pattern unit 110 stores a plurality of information of patterns or designs (hereinafter referred to as patterns) to be embroidered with cord yarn using an embroidery machine, and provides pattern information of the cord yarn embroidery selected by the control unit.

The control unit 120 loads and analyzes the pattern information of the cord yarn embroidery selected from the pattern unit, outputs a swing control signal for controlling the cord yarn not to overlap the needle position of the embroidery machine, and proceeds to the selected pattern of the cord yarn embroidery. Alternatively, the motor 130 is controlled to the home position, which is a designated initial position before starting, and when the production of the cord yarn embroidery is completed, the motor 130 is controlled and monitored to restore to the home position. 130 and the calculation unit 140, respectively.

In addition, when the control unit restores the motor to the home position, the control unit rotates the motor in one of the designated directions.

The operation unit 140 accumulates a swing control signal applied to the motor 130 to produce the cord yarn embroidery of the pattern selected by the control unit 120 from an origin position value of the motor 130. do.

The control unit controls the motor 130 to swing left and right to a specified value for the cord yarn embroidery production of the selected pattern, and when the value of the swing control signal is applied to the operation unit 140, the operation unit 140 is applied. The calculated swing control value is accumulated based on the origin position value.

That is, when the swing control value is cumulatively calculated from the start of the cord yarn embroidery production of the selected pattern to completion, the current controlled position of the motor 130 is rotated to the left or right based on the origin point. You can check the angle value of the degree of rotation.

The input unit 150 accesses the control unit and searches various cord yarn embroidery patterns stored in the pattern unit, selects any one, and inputs various command signals such as starting or stopping embroidery production.

The motor 130 is a stepping motor that is rotated left or right by an angle value specified by the swing control value of the controller 120, and includes an optical encoder or a sensing means (hereinafter, sensing means). The swing direction and the rotational movement angle are precisely detected using the ". &Quot;

Referring to Figure 5 describes the cord yarn supply control method of the embroidery machine by an example of the present invention, the process of loading; Ongoing process; And recovering; It includes a configuration.

Hereinafter, with reference to the accompanying Figure 5, the cord yarn supply control method of the embroidery machine according to an example of the present invention will be described in detail.

The controller 120 of the embroidery machine monitors each functional unit including the input unit 150, and when it is confirmed that a control command of an operating state for producing cord yarn embroidery is input from the input unit (S110), the input unit 150 Searches for the pattern unit 110 and reads and loads information of the selected cord yarn embroidery pattern (S120).

When the cord yarn embroidery pattern information is retrieved from the pattern unit 110, a plurality of patterns information recorded through the display unit not shown in FIG. 4 is retrieved.

The control unit analyzes the loaded cord yarn embroidery pattern information, checks the swing control signal of the cord yarn for embroidery of the cord yarn, and controls the motor 130 to recover to the origin check position, which is the initial position (S130).

At this time, the controller 120 notifies the operation unit 140 of the restored state in which the motor 130 is controlled to the value of the origin check position.

Controlling the motor 130 to recover to the origin check position as described above supplies the cord yarn at the correct position designated by the cord yarn embroidery pattern, and makes the quality of the cord yarn embroidery product produced uniform. The motor 130 is accurately rotated by a predetermined angle or a value of left turn and right turn by a sensing means integrally provided, and returns a controlled result.

When the control unit 120 confirms that the motor 130 is controlled to the origin check position and is restored, the control unit 120 proceeds to produce the cord yarn embroidery product by the loaded cord yarn embroidery pattern (S140).

In order to produce the cord yarn embroidery product, the controller 120 outputs a control signal for swinging the motor 130 by a predetermined value to the motor 130 and at the same time outputs the control unit 140 to the operation unit 140. Is authorized.

The operation unit 140 accumulates and stores the swing control signal values of the left and right rotations applied from the controller 120 based on the origin position value (S150).

The control unit 120 performs swing control on the motor 130 until the production of the loaded cord yarn embroidery pattern is completed, and applies the swing control value to the operation unit 140 to continue the cumulative calculation (S160).

When it is determined by the control unit 120 that the production of the cord yarn embroidery is completed, the cumulative calculated value is received from the operation unit 140, and the analysis is performed to restore the motor to the home position (S170). The motor 130 rotates the motor in one designated direction when restoring to the origin check position.

The control unit 120 controls the motor to restore the home position when the control command for checking the home position is input from the input unit while the embroidery is in progress and the initial state when the power is turned on. In addition, when recovering to the origin check position, the control unit controls the operation unit to initialize the accumulated value and accumulates again.

The recovery process to the origin check position will be described in detail. For example, if the swing control value calculated by the operation unit is less than the value of the origin position in the state where the cord yarn embroidery production is completed, the control unit sets the motor to a positive value. Direction to control more than the absolute value of the-value to rotate more in the + value direction than the origin check position, and again in the direction of the-value to restore to the origin check position.

When the motor is restored to the home position check position, for example, the control unit is set to be designated to rotate counterclockwise (COUNTER CLOCK WISE: CCW), and will be described in detail later.

If it is confirmed by the controller that the final cumulative calculated value is rotated more in the counterclockwise direction than the origin check position, the motor is controlled to rotate more clockwise (CLOCK WISE: CW) than the origin check position, and again counterclockwise. Rotate in the direction (CCW) to control and return to the home position.

In addition, when it is confirmed by the controller that the final cumulative calculated value is rotated in the clockwise direction CW than the origin confirming position, the controller continuously rotates clockwise to restore the origin verifying position and monitors.

In the case of restoring to the origin check position as described above, designating the rotation direction of the motor in one direction is to reduce an error that may occur due to the mechanical gap or play of the motor.

When the cord yarn embroidery production is completed as described above, the home position checking position recovery process of the motor will be described with reference to FIG. 6.

6 is an explanatory view of a procedure for recovering the origin check position of the apparatus for supplying the cord yarn in the embroidery machine according to an example of the present invention.

In the accompanying FIG. 6, it is described that the motor is controlled to an initial position or origin check position, and the motor is set to rotate counterclockwise, for example, when the motor moves to the origin check position.

The motor pulley 135 is fixed to the shaft of the motor 130, and rotates the same by the rotation of the motor. The motor pulley 35 transmits the rotational movement to the nipple pulley 100 by the timing belt 145.

For example, the origin check position of the motor pulley 135 is the 3 o'clock direction of the clock, and the nipple pulley 100 is also the origin check position when the cord yarn hole 70 is the 3 o'clock direction of the clock. .

In response to the swing control signal of the controller, the motor rotates left and right by a controlled angle, and at the same time, the motor pulley 135 rotates in the same direction and angle, and the nipple pulley 100 is a timing belt 145. By rotating in the same direction, the rotation size is larger.

The outer diameter ratio of the motor pulley 135 and the nipple pulley 100 is set to 4: 1, for example.

When the motor pulley 135 rotates as described above, the nipple pulley 100 rotates four times, and thus, the nipple pulley 100 rotates at an angle four times the angle at which the motor pulley 135 rotates. That is, since the rotational movement of the nipple pulley can be controlled quickly, the production speed of the cord yarn embroidery is improved. The outer diameter ratio of the motor pulley and the nipple pulley was found to be optimally set to a value of 4: 1 by repeated experiments, and other selected values may be applied.

6 is a state in which the origin of the motor 130 is in the 2 o'clock direction, for example, in a state where the embroidery machine has finished producing the cord yarn embroidery pattern.

At this time, the control unit receives the cumulative final value of the swing control value from the calculation unit 140 confirms that the origin of the motor is further rotated by the accumulated value in the CCW direction from the origin check position, clockwise (CLOCK WISE: CW After controlling to rotate beyond the origin check position, rotate it to CCW direction and control and confirm to recover to origin check position.

6 is a state in which the origin of the motor is in the 4 o'clock direction, for example, in the state where the embroidery machine has finished producing the cord yarn embroidery pattern.

At this time, the control unit receives the cumulative calculated final value of the swing control value from the calculation unit 140 confirms that the origin of the motor 130 is further rotated by the cumulative calculated value in the CW direction from the origin check position, and rotates in the CCW direction Control and check to recover to the origin check position.
