Referring to FIG. 6, in the control device that controls each part of the bobbin winder of the present invention described above, a central processing unit (hereinafter referred to as CPU) 75 has a read-only memory (hereinafter referred to as RO).
A read/write memory (hereinafter referred to as RAM) 77 is connected, and an input/output device 78 is connected to the CPU 75.
is connected. The bobbin winding amount detection switch 32 is connected to the input/output device 78 , and the pulse motor drive device 79 is connected to the input/output device 78 .
An arm pulse motor 24 is connected to 9, and an arm origin sensor 21 is further connected to the arm pulse motor 24. Further, a pulse motor drive device 80 is connected to the input/output device 78, a moving axis pulse motor 55 is connected to this pulse motor driving device 8o, and the origin of the moving axis moving axis 47 is driven by the moving axis pulse motor 55.

Next, the operation of this embodiment will be explained with reference to flowcharts shown in FIGS. 7, 8, and 9. First, when the power is input and started, the CPU 75 is reset and outputs an off signal to the motor drive device 81 to prevent the main drive shaft motor 38 from rotating (step 1). Next, when an ON signal is output to the solenoid drive device 82 and power is applied to the solenoid 59 to energize it, the plunger 60 is retracted as shown by the solid line in FIG.
moves in the direction of the arrow against the spring 70 as shown in FIG.
is attracted to the left end face of Further, the gate piece 84 is
Move to the right side of the figure to prevent the bobbin 7 from falling (step 2). Next, an off signal is output to the motor drive device 83 to stop the hopper motor 3 (step 3).
. Then, subroutine 1 in FIG. 8 is called. This subroutine 1 is a program for moving the arm 12 to the origin. When the arm 12 is moved to the original position, the shaft of the bobbin 7 located at the lowest end of the bobbin guide groove 8 is fitted into the bobbin holding portion of the arm 12 (step 4).

Next, subroutine 2 is called. As will be described later, this subroutine 2 is a program for moving the moving axis 40 to the origin position (step 5). Furthermore, by outputting N1 pulses of a clockwise direction signal (CW) to the pulse motor drive circuit 79, the arm pulse motor 24 rotates.
Move the support part 11 of the arm 12 and the bobbin 7 to the center position of the main shaft 33 (step 6).Next, when only clockwise (CW) N2 pulses are output to the pulse motor drive circuit 80, the moving shaft pulse motor 55 starts clockwise. By rotating in the direction (CW), the thread 85 is sandwiched between the left end surface of the driven shaft 40 and the bobbin 7 (step 7), and subroutine 1 is called and the arm is moved to the position where the next bobbin 7 is supplied. 12 (Step 8) 6 Next, when an off signal is output to the solenoid drive device 82, the force of the solenoid 59 that pulls the plunger 60 is released, and the force of the spring 70 moves the scissors operating plate 62 to the left in the figure. By moving,
The scissors operating members 64.65 are the scissors members 66a, 66b.
, the scissors 66 close,
Thread 85 is cut. Further, the gate member 84 moves to the left, and the bobbin with the thread 85 wound thereon rolls down the inclined portion 86 in FIG. 1 and is stored in the bobbin receiving box 87 (step 9).

Next, an on signal is output to the motor drive device 81. As a result, the main drive shaft motor 38 rotates, and the thread 85 is wound around the bobbin 7 held between the main drive shaft 33 and the driven shaft 40 (step 10). Next, a counterclockwise direction signal is sent to the pulse motor drive circuit 80 by N3. Outputs only pulses. As a result, the driven shaft 40 moves slightly to the right in FIG.
wrapped around. Since the bobbin 7 continues to be held between the main drive shaft 33 and the spindle 42, the thread continues to be wound (step 11) 6 Next, when an ON signal is output to the motor drive device 83, the homper motor 3 slowly rotates, and the bobbin guide 6 As a result, the bobbin 7 is supplied to the bobbin guide groove 8 (step 12). The thread winding amount detection switch 32 is read (step 13). Then, the bobbin winding amount detection switch 32
It is determined whether the is on or not, and if it is off, step 13
Jump to. Here, when a certain amount of thread adjusted by the bobbin winding amount adjustment knob 31 is wound on the bobbin, the thread winding amount detection switch 32 is turned on, so when this on signal is detected (step 14), the motor drive device 81
An off signal is output to stop the main drive shaft motor 38 (step 15). Next, an off signal is output to the motor drive device 83 to stop the hopper motor 3 (step 16).
Then, when an ON signal is output to the solenoid drive device 82, the scissors 66 open as described above, and the thread pulling member 71
(Step 17)
Also, subroutine 2 is called, the moving shaft 47 and the driven shaft 40 are moved to the origin position, and the wound bobbin 7 is dropped downward. Thereafter, the process jumps to step 6 and performs the operations from step 6 to step 18 described above.

Next, subroutine 1 in FIG. 8 will be explained.

First, a counterclockwise direction signal of 1 is applied to the pulse motor drive circuit 79.
A pulse is output (step 19). And arm 12
The arm origin sensor 21 of is read through the input/output device 78 (step 20), and.

It is determined whether the arm origin sensor 21 is on or off, and if it is on, it jumps to 19, and if it is off, it jumps to 19.

Return. Here, the OFF state is a state in which the arm 12 blocks the light emitting element and the light receiving element of the arm origin sensor 21, and the origin position is where the arm 12 changes from the ON state to the OFF state.

Next, subroutine 2 will be explained. First, one pulse of a counterclockwise direction signal (CCW) is output to the pulse motor drive circuit 80 (step 22). Then, the moving axis origin sensor 5
8 is read through the input/output device 78. (Step 23). Here, if the movement axis origin sensor 58 is on, the process jumps to step 22, and if it is off, the process returns.

The state in which the moving axis origin sensor 58 is off is the state in which the sensor slit 57 in FIG. 2 blocks the light emitting element and the light receiving element of the moving axis origin sensor 58, and in the state where it is not blocked, it is turned on. The point where the moving axis origin sensor 58 changes from on to off becomes the origin of the moving axis 40.

In this way, in this embodiment, by electrically controlling each drive device, the control becomes simple and the configuration becomes simple.

[Effect of the invention] Since the present invention is configured as one or more.

Since the drive device of each part is electrically controlled by the control device, there is no need to set the timing with cams or levers as in the past, and it can be controlled while keeping the timing electrically, simplifying the configuration and reducing maintenance. It also has the advantage of being simpler.
