(Problem to be solved by the invention) Therefore, in the past, when a running abnormality occurs in the knitting yarn between the tension applying means and the yarn take-up spring, there is a problem that the running abnormality cannot be detected. It was hot. From this, even if there is a running abnormality in the knitting yarn, the carriage continues knitting operation, resulting in an accident in which excessive tension is applied to the knitting yarn and the knitting yarn is cut, or the carriage is cut off due to the absence of knitting yarn. Due to the idle operation, a problem occurs in which the knitted stitches are detached from the knitting needles.

Next, the operating circuit (electrical circuit) of the autocarriage 3 to which the sensing switch 16 is connected will be briefly explained with reference to FIG.

When the power supply voltage VDD is applied to the electric circuit before starting the autocarriage 3, the capacitor C1

In this state, when the normally open start switch SW1 is turned on, the gate voltage is applied to the thyristor SCR and the thyristor SCR is turned on, and at the same time, the transistors TR1 and TR2 are turned on, and the colentor current turns on the autocarriage 3.
The drive motor M is driven.

In the operating state of the drive motor M, the comparator
CMP has a transistor TR on its positive input terminal.
2. Since a voltage corresponding to the sum of the voltage drops across the resistor 6 (actually about 2.1V) is applied, it becomes higher than the reference voltage of the negative terminal (also about 0.6V), and an H level signal is output from the output terminal. Output.
Therefore, when the start switch SW1 is turned on, the drive motor M is continuously driven.

When the sensing switch 16 is turned off, the power supply voltage VDD applied to the drive motor M is momentarily cut off, and the positive input terminal of the comparator CMP becomes approximately 0.1V, and the negative input terminal becomes approximately 0.1V. Since the voltage is lower than the reference voltage, the output terminal of the comparator CMP becomes L level. Then, the thyristor
At the same time SCR is turned off, transistor TR
1, TR2 is turned off, thereby stopping the drive motor M. That is, the operating circuit is opened using the momentary interruption of the power supply voltage VDD when the sensing switch 16 is turned off, and as a result, the drive motor M is stopped. In addition, to restart this,
It is necessary to turn on the start switch SW1 again, and the drive motor M will not be restarted automatically when the power supply voltage VDD is restored.

In addition, the electric circuit of this example includes the L of the comparator CMP.
A buzzer that continues sounding for a predetermined period of time after receiving a level signal.
BZ is incorporated through the transistor TR3, and the buzzer BZ temporarily sounds when the motor M stops when the sensing switch 16 is turned off, notifying the knitting machine user (knitting worker) that the drive motor M has stopped. I'm starting to do that. Note that it is also possible to use an indicator lamp instead of the buzzer BZ, or to use the buzzer BZ and an indicator lamp together.

(Effects of the invention) As described above, according to this invention, when a tension of more than a predetermined value is applied to the knitting yarn between the tension applying means and the yarn take-up spring, the approaching/separating means releases the yarn connection. Since the switch actuating member moves relative to the mating member, the switch is actuated, thereby making it possible to detect abnormalities in the running of the knitting yarn. Furthermore, when the knitting yarn is absent, the switch actuating member moves together with the yarn engaging member to operate the switch, thereby making it possible to detect an abnormality in the running of the knitting yarn. Therefore, it is possible to prevent an accident in which the knitting yarn is cut due to excessive tension acting on the knitting yarn, and to prevent idle operation of the carriage due to the absence of the knitting yarn.
