[Industrial applications]

[Prior art]

 In general, a spinning machine is wound by a bobbin mounted on a spindle while twisting a yarn stretched by a bottom roller and a front roller, and at this time, the bobbin is vertically displaced by a lifter mechanism. There is a need.

The drive source of the lifter mechanism of the conventional spinning machine is shared with the main shaft induction motor. However, the speed of the lifter mechanism depends on the condition of the yarn to be produced, and the rotation of the main shaft induction motor depends on the relationship with the main shaft. It is necessary to drive at a rotational speed different from the number.

[0004]

[Problems to be solved by the device]

 In order to make the speed of this lifter different from the rotation speed of the induction motor for the spindle, it is necessary to replace it with a gear that has the number of combined teeth that matches the set conditions, but this work requires some time, so production efficiency is increased. There is a problem that the worker is reluctant to do this work because the work is lowered and the hands are soiled during the replacement work.

[0005]

[Means for Solving the Problems]

 The present invention provides a spindle control device that supplies electric power to a spindle induction motor that rotates a spindle, and controls the spindle induction motor to a set speed by a signal from an encoder connected to the spindle induction motor. And a front roller driving device that drives a front roller servo motor that rotates the front roller, and a back roller driving device that drives a back roller servo motor that rotates the back roller. A sequencer to which a key panel for inputting is input, a ratio setting device for a lifter that inputs a signal from the sequencer and a rotation signal of the spindle induction motor from an encoder connected to the induction motor for the spindle, and a ratio setting device for the lifter. Drives the lifter induction motor at the number of revolutions related to the spindle induction motor and the yarn count by the signal from the ratio setting device. Is shall.

[0006]

[Action]

 In the present invention, when power is supplied from the power supply, the spindle control device supplies power to the spindle induction motor to rotate the spindle induction motor.

At this time, the rotation speed of the spindle induction motor is detected by the encoder, the signal from this encoder is input to the sequencer, and the output signals of the front roller and back roller ratio setting device are respectively output by the signal from the sequencer. Set the servo motor of to rotate at an appropriate ratio.

Further, when a numerical value related to the thread count is input by the key panel connected to the sequencer, a signal related to the thread count is input from the sequencer to the lifter ratio setting device, and further, the encoder for the spindle is input. By inputting the rotation speed of the induction motor to the lifter ratio setting device, the lifter ratio setting device follows the lifter drive device in proportion to the rotation speed of the spindle induction motor at that time, and is related to the yarn count. Input the signal.

Due to this signal, the lifter drive device always causes the lifter induction motor to be associated with the yarn count and rotates at a rotation speed proportional to the rotation speed of the spindle induction motor.
