The main body 1 is provided with a workbench 8 below the arm 3, and a lower iron 9 is erected on the workbench 8. Further, an upper iron 10 is attached to the tip of the arm 3, and by swinging the arm 3, the upper iron 10 can be brought into pressure contact with the lower iron 9.

A steam pipe (not shown) is connected to the upper iron 10, and steam is automatically blown out from the lower end surface of the upper iron 10 when the upper iron 10 is pressed against the lower iron 9. ing. Further, a vacuum pipe (not shown) is connected to the lower iron 9, and a vacuum switch (not shown) is activated at the same time as the upper iron 10 separates from the lower iron 9, and the steam is removed by the lower iron 9. It is made to be able to be inhaled.

As shown in FIGS. 2 and 3, immediately before the main body 1,
A footboard 11 is provided on the floor surface, and the footboard 11 includes:
Two foot switches 12, 13 are provided in series. This foot switch 12.13 is a safety device switch 14 (see Fig. 1), which will be described later. : The drive cylinder muff is connected to a 200V power supply 19 via a solenoid valve 15, and the solenoid valve 15 of the drive cylinder 7 is activated only when both the foot switch 12 and the foot switch 13 are stepped on at the same time. A drive cylinder 7 is adapted to be driven. still,
The safety device switch 14 is normally turned on. A drive cylinder control switch 16 is provided directly below the drive cylinder 7 , and the drive cylinder control switch 16 is connected in series to the solenoid valve 15 of the drive cylinder 7 . The drive cylinder control switch 16
The operator 16a is in contact with the outer peripheral surface of the drive cylinder 7. In addition, drive cylinder control switch 1
The operator 16a of No. 6 is always biased in the protrusion direction,
The drive cylinder control switch 16 is turned off when the operator 16a is in a protruding state. Therefore,
The drive shaft 7a of the drive cylinder 7 extends and the drive cylinder 7
When it moves upward, the operator 16a of the drive cylinder control switch 16 becomes in a protruding state, and the drive cylinder control switch 16 is turned off. An upper trowel control switch 17 is provided near the rear end of the arm 3, and an operator 17a of the upper trowel control switch 17 is connected in series to the solenoid valve 15 of the drive cylinder 7. . The operator 17a of the upper trowel control switch 17 is in contact with the upper surface of the arm 3. Further, the operator 17a of the upper trowel control switch 17 is always biased in the protruding direction, and the upper trowel control switch 17 is turned on when the operator 17a is in the protruding state. Therefore,
When the drive shaft 7a of the drive cylinder 7 extends, the rear end of the arm 3 moves upward, and the upper iron 10 comes into pressure contact with the lower iron 9, the operator 17a of the upper iron control switch 17 is pushed in, The upper trowel control switch 17 is turned off. A holding circuit]8 is connected in parallel to the upper trowel control switch 17, so that even if the upper trowel control switch 17 is turned off, the solenoid valve 15 of the drive cylinder 7 remains in operation for a certain period of time. It is like that.

Then, after a certain period of time has passed, the solenoid valve 15 of the drive cylinder 7 is cut off from the power source 19. Note that the holding time of the holding circuit 18 can be set arbitrarily by a timer 20.

The rear end of the arm 3 is always urged downward by a spring 21, and the tilting rod 5 is also urged downward by a spring 21.
2, it is constantly biased in the forward tilting direction. As a result, after the solenoid valve 15 of the drive cylinder 7 is cut off from the power supply 19, the rear end of the arm 3 moves downward due to the biasing force of these springs 21 and 22, and the tilting rod 5 tilts forward. , the tip of the arm 3 moves upward to release the pressed state between the upper iron 10 and the lower iron 9.

As shown in FIGS. 1 and 2, a U-shaped safety frame 23 is provided below the upper iron 10, and both ends of the safety frame 23 are bent upward to connect the arms. It is rotatably supported by a support part 24.24 provided at the tip of 3. The support end 23a of the safety frame 23 is connected to the safety device switch 14 via the actuator 25 (Fig. 3), and the safety frame 23 is connected to the upper +1J
i (arrow A in Figure 3), the safety device switch 14 is turned off, the solenoid valve 15 of the drive cylinder 7 is cut off from the power supply 19 (see Figure 2), and the tip of the arm 3 is immediately turned off. It is designed to move upward. A manual switch 26 is connected in parallel to the safety device switch 14, and the safety device switch 14 is connected in parallel to the safety device switch 14.
When the safety device switch 14 is turned off, the safety device switch 14 can be returned to the on state by operating the manual switch 26.

Next, the operation of this embodiment will be explained.

First, when the foot switches 12 and 13 provided on the footboard 11 are simultaneously stepped on, the solenoid valve 15 of the drive cylinder 7 is operated and the drive shaft 7a is extended. The extension of the drive shaft 7a causes the rear end of the arm 3 to move upward via the tilting rod 5 and the connecting rod 4, and the upper iron 10 provided at the tip of the arm 3 comes into pressure contact with the lower iron 9. At this time, both the drive cylinder control switch 16 and the upper trowel control switch 7 are in the OFF state, but a holding circuit 18 connected in parallel to the upper trowel control switch 17 holds the solenoid valve of the drive cylinder 7 for a certain period of time. 15 remains in operation, the upper iron 10 is in pressure contact with the lower iron 9 for a certain period of time, and during this pressure contact, the steam blown out from the lower end surface of the upper iron 10 may damage the shoulders of clothes, etc. Can be molded.

After a certain period of time has elapsed, the holding circuit 18 is released and the solenoid valve 15 of the drive cylinder 7 is cut off from the power supply 19. The arm 3 is then moved by the biasing force of the springs 21 and 22.
As the rear end moves downward and the tilting rod 5 tilts forward,
The tip of the arm 3 moves upward, and the pressed state between the upper iron 10 and the lower iron 9 is released. In this way, the upper iron 10 is pressed against the lower iron 9 for a certain period of time, and the steam is blown out from the lower end surface of the upper iron 10. Therefore, in the unlikely event that a worker accidentally touches the lower iron 9 and the upper iron 10, If your hand gets caught between the two, there is a risk that your hand will be injured by the pressure and steam from the upper iron 10. In order to deal with this, in the present invention, as described above, the safety frame 23 is disposed below the upper iron 10, and the switch for the safety device is turned off in conjunction with the upward tilting of the safety frame 23. It was configured as follows. Therefore, even if the worker accidentally gets his or her hand caught between the lower trowel 9 and the upper trowel 10, the worker's arm will come into contact with the safety frame 23, causing the safety frame 23 to tilt upward (arrow A in Figure 1). As a result, the safety device switch 14 is turned off, the solenoid valve 15 of the drive cylinder 7 is cut off from the power supply 19 (see Figure 3), and the tip of the arm 3 quickly moves upward (see the arrow in Figure 1). C, arrow in Figure 2), it won't hurt your hands. After the safety device switch 14 is turned off as described above, the solenoid valve 15 of the drive cylinder 7 is cut off from the power source 19 and the garment molding machine does not operate. By operating the manual switch 26, the safety device switch 14 can be returned to the on state, so that the subsequent molding work can be continued.

(Effects of the Invention) With the above configuration, the present invention allows the upper trowel to automatically move upward even if the operator accidentally gets his hand caught between the lower trowel and the upper trowel. Therefore, the operator does not need to take any new conscious action to move the upper trowel upward, which has the great effect of improving safety.
