- the CPU 7 inputs an output of the current sensor 9 through an A/D converter and an interface, which are not shown in the figure.
- the CPU 7 obtains a rate of change of current in accordance with an output signal from the current sensor 9, and when the rate of change of current exceeds a set value, the CPU 7 judges occurrence of a broken-state of thread, and then stops supply of power to the spindle motor 2 of the corresponding spindle and also turns on the display portion 10a for displaying the broken-state of thread. Further, the spindle motor 2 is provided with a sensor (not shown) for detecting its rotational speed. In the case where the rotational speed of the spindle motor 2, which is detected by the sensor, largely deviates from a predetermined value, the CPU 7 judges that an abnormality has occurred, and then stops the spindle motor 2 and also turns on the display portion 10b for notifying abnormality.
- all the spindles of the spinning frame is divided into a plurality of groups, one group consisting of 48 spindles, for example.
- All the spindle computers 6 in each of the groups are connected with a section control unit 12 dedicated to one of the groups through a communication line 13, respectively.

- the CPU 18 inputs data on the broken-state of thread and abnormality of each spindle in a predetermined cycle from each-of the spindle computers 6, and then calculates the actual spinning length of each spindle based on the data and a detection signal from the counter 22 and also totalizes the number of times of the broken-state of thread every spindle.
- the RAM 20 is provided with a storage region for storing the number of times of the broken-state of thread and a storage region for storing the actual spinning length, which correspond to each spindle.
- the CPU 18 totalizes the number of times of broken-state of thread and stores the number in the storage region that corresponds to the spindle in which the broken-state of thread occurs. Further, the CPU 18 stores the difference between the count value of the counter 22 at the time of a stop due to the broken-state of thread or abnormality and the count value of the counter 22 at the time of restarting of spinning for each spindle.
- the spinning length corresponding to the stored difference of the count value is subtracted from the spinning length obtained from the count value of the counter 22 at that time, thereby obtaining the actual spinning length at that time. In the case where spinning is not restarted until the time of the calculation of the actual spinning length, the spinning length until the time of the stop corresponds to the actual spinning length.

- the information on broken-state of thread includes information on whether each spindle is in the broken-state of thread at present or not, and information on the total number of times of broken-state of thread.
- the CPU 25 When the number of times of broken-state of thread exceeds a predetermined number of times N ⁇ set in advance in a predetermined period (during one doff in this embodiment) in a certain spindle, the CPU 25 outputs a starting prohibition command signal for prohibiting starting of the spindle motor 2 of the spindle to the corresponding spindle computer 6 through the frame computer 15.
- the predetermined number of times N ⁇ differs depending on the spinning conditions, and is set to several times, for example.
- the spindle computer 6 turns on the display portion 10b of the corresponding spindle and also does not start the spindle motor 2 until a starting prohibition cancellation command signal is input even if the switch 11 is turned on or a starting signal is input from the frame computer 15.
- the host computer 24 can display various items of control information on the color display 29 by the operation of the input device 28 and also can output the starting prohibition cancellation command signal to the frame computer 15.

- Each of the spindle computers 6 judges existence/non-existence of a broken-state of thread and existence/non-existence of abnormality of the corresponding spindle in a predetermined cycle.
- the spindle computer 6 acknowledges the broken-state of thread, it stops the spindle motor 2 and also turns on (drives) the display portion 10a.
- the spindle computer 6 acknowledges the abnormality, it stops the spindle motor 2 and also turns on (drives) the display portion 10b.
- the spindle computer 6 outputs the existence/non-existence of the broken-state of thread and abnormality to the section control unit 12.
- the CPU 18 of the frame computer 15 inputs data on the existence/non-existence of a broken-state of thread and the existence/non-existence of abnormality from the spindle computers 6 of the respective spindles through the section control unit 12 in a predetermined cycle. Further, the frame computer 15 calculates the actual spinning length of each spindle. Then, the frame computer 15 outputs control information such as information on a broken-state of thread to the host computer 24 during the operation in accordance with the command from the host computer 24. After the stop due to the state of a full spool, the frame computer 15 outputs data on the count value of the total number of times of broken-state of thread and the actual spinning length of each spindle during one doff to the host computer 24 before resetting the data to zero.
- the host computer 24 retrieves the spindle in which the total number of times of broken-state of thread exceeds the predetermined number of times N ⁇ based on the control data during the operation of the frame, judges that the corresponding spindle is a spindle in bad condition, and outputs a starting prohibition command to the spindle computer 6 of the spindle through the frame computer 15. Further, the host computer 24 calculates efficiency of each spindle and efficiency of each frame in accordance with the actual spinning length of each spindle based on the control data every one doff.
- the host computer 24 notifies each of the frame computers 15 of the number of the spindle to be stopped in carrying out a planned stop to stop a part of the frames and spindles for the adjustment of production. In this case, the spindle or frame with inefficiency is given priority in stopping.
- the manager operates the input device 28 of the host computer 24 and outputs the starting prohibition cancellation command signal to the spindle having been subjected to the repairing processing through the frame computer 15.
- the manager displays the spindle in a starting prohibition state on a screen of the color display 29 in canceling the starting prohibition.
- the manager selects the spindle in which the starting prohibition should be cancelled and clicks the display of the spindle on the screen.
- the starting prohibition cancellation command to the spindle is output to the frame computer 15 to which the spindle belongs, and the display of the spindle on the screen is cancelled.
- This embodiment has the following effects.
- the present invention is not limited to the above embodiment, and may be embodied as described below, for example.

- one or both of the frame computer 15 and the host computer 24 may compare the total number of times of broken-state of thread and the predetermined number N ⁇ in one doff and judge the spindle in which the total number exceeds the predetermined number N ⁇ is a spindle in bad condition.
- the starting prohibition command may be output to the spindle computer 6 of the spindle.
- a method of detecting broken-state of thread of each spindle is not limited to a method of detecting a supply current to the spindle motor 2 by the current sensor 9, and a sensor for detecting broken-state of thread of another method may be used.
- the display condition may be changed, for example, the broken-state of thread and the abnormality may be notified by using a combination of continuously turning on a light and switching a light on and off by using one display portion, instead of providing separately the display portion 10b for notifying abnormality and the display portion 10a for displaying broken-state of thread.
- the number of components is reduced, and the manufacturing cost can be reduced.
- the period for totalizing the number of times of broken-state of thread for judging whether a spindle is a spindle in bad condition or not may be set in a plurality of doffs, working hours of a shift worker, or days instead of one doff as one unit.
