* Invention The invention of claim 4 is configured as follows assuming invention 請 Motomeko 2 or claim 3.

[0013]
The processing device (17) stops the packaging machine when the input signal from the sensor (18b, 29) is not within the predetermined period (T), and thereafter, when the activation signal to the packaging machine is input, The drive control state (A) based on the input signal from the sensor (18b, 29) is switched to the drive control state (B) based on time. In the present invention, the operator can easily switch the drive control state (A, B).

[0028]
In the case of the drive control state A based on the detection signals from the both sensors 28 and 29, this drive control state A is the case where the sensor 29 is normal.
In step S3, the drive motor 24 is rotated forward by the drive signal. Since the sensor 29 at the extrusion position Q is normal, the process proceeds to steps S4, S5, S6, S7, S8 and S9. In step S5, the sensor 29 at the extrusion position Q detects the extrusion member 27 and determines whether or not the signal is input (whether the sensor 29 is turned on). When the sensor 29 is turned on, the drive motor 24 is stopped in step S6. At step S7, the drive motor 24 is reversely rotated by the drive signal. In step S8, the sensor 28 at the standby position P detects the pushing member 27 and determines whether the signal is input (whether the sensor 28 is turned on). When the sensor 28 is turned on, the drive motor 24 is stopped in step S9.
