FIG. 3 shows a motor controller 7 of the sewing machine 5.
5 is a time chart showing the signals obtained in FIG. 5, wherein the horizontal axis represents time, and the vertical axis represents signals of respective units. FIG. 4 is a flowchart for explaining an operation for initially setting a counting condition in the embodiment. FIG. 5 is a flowchart for explaining the actual counting process.

First, a counting condition is set in the condition memory 19 of the work volume counter 1. To explain the operation for this, when the power is turned on, first, the operator's code number etc.
The unique number of the worker is read from the barcode reader 3 into the information processing device 17 of the work volume counter 1 (step S401 in FIG. 4). Next, an item code number such as a design number is read from the barcode reading device 3 to the information processing device 17 of the work volume counter 1 (step S402). Further, for example, the process code numbers such as the attachment of the collar and the attachment of the button are read from the barcode reader 3 to the information processing device 17 of the work volume counter 1 (step S403). When these are completed, it is determined whether or not the counting condition is already set in the information processing device 17 of the work volume counter 1 (step S404), and if the counting condition is set (step S404).
404: Y), the sewing operation is immediately started without performing the previous operation, and the process proceeds to the actual counting process. If it is not set (step S404: N), the condition setting start switch among the operation buttons 13 is pressed. Then, a trial sewing operation is performed to capture a plurality of signals from the motor controller 7 (step S406).

Here, the one selected as the counting condition signal stored in the condition memory 19 in the above step S406 indicates the motor start shown in FIG. 3 which is inevitably generated in the normal sewing operation in order. A signal As, a signal C indicating the number of stitches, a signal Bp indicating motor stop, a signal Du indicating press-up of the presser member, or a signal E indicating thread trimming. Here, the number of stitches signal is the number of stitches set in the counting condition (n ± 5) including the permissible range ± 5 in the reference number of stitches n for completing one sewing operation.

However, if a signal indicating motor activation is not input from the motor controller 7 to the information processing device 17 in the above order, the process does not proceed to the next step but is repeated as it is (step S501: N).

For example, when the sewing machine motor is temporarily stopped and restarted in order to insert a quality confirmation label during sewing, the signal Bs input from the motor controller 7 to the information processing device 17 is not a counting condition signal, so S50
At 1, the count is canceled, and the counting step S501 is repeated.

When a signal As indicating motor start is input (step S501: Y), and after the motor starts, when the stitch number signal C reaches the count condition setting stitch number n ± 5 (step S502: Y), the next step is performed. Proceed to the determination step. If the signal C does not reach the number of stitches set for the counting condition, this step is repeated (step S502: N).

After the number of stitches set in the counting condition is reached (step S5)
02: Y), if there is an input of the signal Bp indicating motor stop (step S503: Y), the process proceeds to the next step.
The signal Ap indicating the motor stop generated before the number of stitches set for the counting condition is achieved is canceled as a counting condition signal (step S502: N).

After the input of the signal Bp indicating motor stop (step S503: Y), if there is a signal Du indicating raising of the presser foot member or a signal E indicating thread trimming (step S503).
504: Y), it is determined that the normal sewing has been completed, and an object completion signal for incrementing the count value by +1 is output (step S505).

The operation in each of the above steps is continued until the sewing operation is completed, and the number of normally sewn sewing is added (step S506: Y).
