回路5の出力部とは互いに電気的に接続されている。A movable jig 3 that is moved up and down by the valve 2 is connected to the shaft of the valve 2 . This movable jig 3 is operated by turning on the position detection switch 4 when the valve 2 is lowered.
When the input signal a is sent to the ltll circuit 5 and the valve 2 is rising, the position detection switch 6 is turned on and the control circuit 5 is turned on.
It is designed to send an input signal to the Air tubes 7a and 7b are connected to the upper and lower ends of the cylinder portion 1, respectively, and these air tubes 7a and 7b are connected to self-holding type electromagnetic valves 8, respectively. Said solenoid valve 8 and control company
The output portions of the circuit 5 are electrically connected to each other.

る。The control circuit 5 then sends output signals a and b to the solenoid valve 8. Specifically, when the valve 2 is lowered and the control circuit 5 outputs an output signal, the solenoid valve 6 starts feeding high pressure air into the air tube 7b. As a result, the movable jig 3 rises. Conversely, when the control circuit 5 outputs the output signal a, the solenoid valve 6 starts sending high-pressure air to the air tube 7a, and the movable jig 3 descends.

FF and output signal a are turned ON. Note that in the conventional case, the output signal is simply turned off. As a result, high-pressure air is sent into the air cylinder 1 through the air tube 7a, the valve 2 is lowered, and the movable jig 3 is also lowered.1 After this, the output signal a is turned OFF with a slight delay, and the work is stopped. finish.

In this case, the output signal a turns OFF and the work ends (normal condition). Also, when it is OFF, it is checked whether the time limit has expired or not. In the case of NO, the input signal a is turned on or off again. If the time limit is exceeded, a trouble alert will be issued. Subsequently, the output signal a from the control circuit 5 is turned OFF, and the output signal A is turned ON. In addition,
In the conventional case, the output signal is simply turned off. As a result, high pressure air passes through the air tube 7b to the cylinder portion 1.
The valve 2 rises and the movable jig 3 also rises. After this, the output unit @b is turned OFF after a slight delay, and the work is completed (in normal operation).

る。According to the above embodiment, if a failure occurs in the movable jig 3 and it stops halfway between the position detection switches 4 and 6, an output signal is sent to the solenoid valve 6 to drive the valve 2 upward or downward. ,
Since the valve 2 in the cylinder part 1 is moved by high-pressure air via the air tubes 7a and 7b, the movable jig 3 does not stagnate in the middle between the position detection switches 4 and 6, and moves to either switch 4 or 6 side. can be moved reliably. Therefore, work can be carried out safely without damage to objects.
