A button 23b, a reverse button 23c for reversing the spangle tape 1 by rotating the drive shaft of the stepping motor 41 and the lower body 44 of the spangle feeder 40 as shown in FIG. An up / down button 23d for driving the cylinder to lower is included.

The solenoid portion includes a jump solenoid 24a for receiving a jump signal of the embroidery machine, a wiper solenoid 24b for receiving a thread timing during the thread trimming operation, and a trimming solenoid for receiving a signal for cutting the thread.

The control unit 30 includes a power supply unit 31, a signal input unit 32, a signal processing unit 33, a signal output unit 34, and a motor driving unit 35. Hereinafter, each block in the control unit 30 will be described. Sequentially described as follows.

First, the power supply unit 31 converts the power supply DC 24V input from the external power supply 10 into a control power source that can be used in the control unit 30, that is, DC 5V and provides it to each block.

In addition, the signal input unit 32 receives a signal input through the sensor unit 21, the key button unit 23, and the solenoid unit 24, changes the voltage level of the input signal, and converts the digital signal in the control unit. It plays a role of filtering for convenience, and the external input signal and the internal control signal are insulated using a photocoupler (not shown).

The signal processor 33 analyzes the signal input through the signal input unit 32 to drive the stepping motor 41 or output an on / off signal for driving the solenoid valve 50 at an appropriate time.

In this case, the signal processor 33 may be classified into three types of signals.

First, purely the signals received from the embroidery machine are the jump solenoid 24a signal, the wiper solenoid 24b signal, and the trimming solenoid 24c signal.

Second, the stepping motor 41 of detecting the sensor signal installed in the outside, that is, the position of the needle bar 6 detected through the needle bar position sensor 21a through the detection signal and the initial position sensor 21b. Rotation detection signal of the main shaft detected by the initial position detection signal and the main shaft rotation detection sensor 21c,

Third, there is a key button input signal that can be operated by the user through the key button unit 23.

A reverse rotation signal for reversely rotating the stepping motor 41 and a rising / falling signal for raising / lowering the cylinder 43 through the up / down button 23d.

Furthermore, the signal processor 33 receives the input signal, processes the signal, and outputs the signal to the outside.

First, most of the output signals are used to control the stepping motor driver 35. That is, it is a pulse signal that controls the direction of the stepping motor 41, or informs the moving distance, and a low power control signal for power saving when not in use,

Second, the cylinder drive signal for controlling the rise / fall of the cylinder 43,

Third, a state output signal for outputting the status display LED 60 to the outside so that the user can monitor the state of the controller 30, that is, the normal operation state, the power saving mode state and other error states.

On the other hand, the signal output section 34, like the signal input section 32, the output signal is a digital signal, the level of the output voltage as a connection for operating the stepping motor 41 or other devices external to the control signal It includes a function to change the.

In addition, the stepping motor driving unit 35 electrically connected to the stepping motor 41 drives the stepping motor 41 according to a control signal transmitted from the signal processing unit 33 through the signal output unit 34. It functions to move a certain distance repeatedly according to the preset movement direction or pulse signal.

The interlocking relationship between each block described above can be summarized as the driving of the stepping motor 41 to the external input signal, the main function of which is a stepping motor whenever an input signal from the embroidery machine, in particular a signal of the jump solenoid 24a is input. 41 is moved by a predetermined distance, and other signals are used to implement additional functions.

Reference numeral 5 denotes a needle, 45 a driving roller for conveying the spangle tape, and 46 a cutter for cutting the spangle tape.

First, the power is turned on to receive power from the power supply 10 to the control unit 30, and then the initialization of the control unit 30 is performed (S1).

That is, the initialization is largely divided into three processes, the initialization of the setting of the variable value or various register values used internally is made first, and the stepping driver 35 for driving the stepping motor 41 next. ), The control signal output value is initialized, and finally the stepping motor 41 is driven to set the correct initial position of the spangle tape 1.

In this case, the correct initial position setting of the spangle tape 1 is performed by the signal processor 33 to determine the signal input through the initial position detection sensor 21b, and according to a preset procedure, the stepping motor driver 35 It is performed by driving the stepping motor 41 through.

On the other hand, after the initialization of the control device is completed as described above, by receiving a signal from the external needle bar position sensor 21a to determine whether to execute the entire control loop (S2).

In this case, if the signal of the needle bar position sensor 21a is off, the current position of the needle bar is determined to be the position where the spangle feeder is not mounted, and the control function of all the spang feeders is stopped. On the other hand, if the input signal of the needle bar position sensor is on (on), the current position of the needle bar is determined to be the position where the spangle feeder is mounted so as to perform the control function of the spangle feeder normally.

In addition, the position of the cylinder is also determined according to the detected signal of the needle bar position sensor 21a (S2). That is, when the signal of the needle bar position sensor 21a is input to the on (on), it is determined that the needle bar is in the position where the spangle feeder is mounted, the lower body 44 according to the drive of the cylinder 43 It must be lowered for mounting the pangle (S3), and in the opposite case, the cylinder 43 must be raised upward (S4).

Thereafter, in the needle bar position sensing step, the current needle bar is determined to be a position where the spanner feeder is mounted, and when the input signal state is on (S5), the spanner is supplied by receiving the signal of the jump solenoid of the embroidery machine. When the jump flag is set (S6) and the signal input of the next jump solenoid is turned off (S7), when the jump flag is set, the jump solenoid is set. Judging by the end of the signal, the stepping motor is rotated (S8) to supply the spangle and to reset the jump flag variable (S9).

On the other hand, when the unnecessary head 3 is stopped by the toggle switch 25 during the spangle embroidery operation of two or more multi-head embroidery machines, the jump solenoid does not generate a signal in the stopped head 3 and the mounted spangle The feeder is stationary without stalling.

When the user receives the key button signal generated by the operation to perform the corresponding function (S10), and outputs the state inside the controller so that the user knows the state of the control device (S11), control of the spangle feeder The step is complete.

All of the above steps are performed repeatedly in an endless loop until the power is cut off. Finally, the control of the spangle supply is terminated as the power is turned off.

In the present invention described above, the signal signal from the sensors or embroidery machines installed on each head is not received from the main machine of the embroidery machine, but the signal is processed by the control unit to drive the solenoid valve or the stepping motor. Product year / manufacturer has an advantage that can smoothly control the spangle feeder regardless of the type of other embroidery machines or automatic single / plural embroidery machines.

In addition, when the power is cut off, trimming, replacing the needle bar, and ending the spangle work, the body of the spangle feeder is raised by the control unit so that it does not interfere with the general embroidery work. When you move to a point, you do not move to running stitches, but jump and move to overcome the limitations of your design.

Moreover, when the power is supplied again after the power is cut off, it is possible to automatically set the position of the spangle tape provided to the spangle feeder to the correct cutting position.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and the general knowledge in the technical field to which the present invention belongs without departing from the spirit of the present invention.
