Even if a new reason for stopping is added, it is only necessary to correct the display data stored in the display data storage means, and it is not necessary to correct some data on the side of a plurality of sewing machines. Since there is no need to change or replace the display means or display means, change the reason for suspension,
The addition is easy and the versatility of the input means and the display means is excellent.

According to the second aspect of the present invention, when the management computer receives a predetermined signal instructing the transfer of the display data from the control device of any of the sewing machines, the control computer of the sewing machine displays the display. Data is transmitted, management is performed when a sewing machine stop signal is received, or when another predetermined signal is input by the input means after the sewing machine is stopped and the management computer receives the predetermined signal. The display computer can transmit the display data to the control device of the sewing machine to display both the stop reason code and the stop reason on the display means. In addition, the same effect as that of the first aspect can be obtained.

According to the invention of claim 3, when the sewing machine stops due to a certain stop reason, the stop-related data collecting means receives the stop reason code corresponding to the stop reason,
Since the stop-related data such as the total number of times the sewing machine is stopped and the cumulative stop time for the stop reason are updated, stop-related data is collected for each stop reason, and the stop-related data is updated every time the sewing machine stops due to the stop reason. be able to. In addition, the same effect as that of claim 1 or 2 can be obtained.

According to the fourth aspect of the invention, the plurality of reasons for stopping include upper thread dropout, upper thread breakage, bobbin bobbin replacement, needle breakage, overload, and break. Thus, when the sewing machine is stopped, the worker inputs the stop reason code corresponding to the stop reason by the input means, so that the stop related data collecting means can collect the stop related data about the stop reason. In addition, the same effect as the third aspect can be obtained.

According to the fifth aspect of the invention, the stop-related data collecting means collects at least data on the cumulative number of times the machine has been stopped due to a break and the cumulative stop time during a predetermined period. When the data is stopped, the stop-related data collection means can update the data on the cumulative number of times the sewing machine has been stopped due to a break and the cumulative stop time, and collect these data for each predetermined period.
In addition, the same effect as in claim 4 is obtained.

According to the sixth aspect of the invention, since the operation panel also serves as the display means and the input means, a display means and an input means different from the operation panel are provided to manage the operation stop state of the sewing machine. It is not necessary to provide the sewing machine, which is advantageous in manufacturing cost. In addition, the same effect as that of any one of claims 1 to 5 can be obtained.
