4 and 5, according to the present invention, when the front end inlet of a vinyl waterproof package 40 having a built-in cellular phone is pushed in and the switch is pressed, the movable heater is lowered to heat the front end of the waterproof pack, A die 22 for placing a waterproof pack 40 containing a cellular phone pushed into the inlet 21 from the sealing body and a die 22 for holding the waterproof pack 40. The die 22 is provided at the inner end of the inlet 21 of the die 22, And a vertically movable guide rod 24 slidably lowered and raising and sealing at the inner end of the sealing machine body at the inlet end of the die 22 in parallel to the left and right of the inlet 21, A movable heater 26 attached to a lower end of the elevator 25 to heat seal and seal the waterproof pack 40 in cooperation with the fixed heater 23 and a movable heater 26 attached to the elevator 25 at every sealing cycle, A cam table 27 for raising and lowering the cam table 27, And a stepping motor 28 which is driven.

In the sealing portion 20, a horizontal sensor hole 29 is formed on the ascending / descending member 25, and a sensor 30 is provided in the sensor hole 29. The sensor 30 senses an obstacle appearing ahead and sends the sensing signal to a stepping motor 28 which is driven in a forward direction for sealing to reverse drive and is electrically connected to the stepping motor 28. The object to be detected is the upper back side of the safety plate described later.

A translator-type bracket 31 is attached to the upper end of the ascending / descending member 25, and the safety plate 32 is provided so as to abut on the bracket 31. A pair of guide shafts 33 are attached to the lower end of the inner surface of the bracket 31 so as to face the ascending and descending member 25. The guide shafts 33 guide the safety plate 32 to move up and down within a limited range Limit activity.

In the safety plate 32, a pair of the action holes 34 into which the guide shaft 33 is inserted are perforated vertically. The active ball 34 is restricted by the guiding shaft 33 in the width of the ascending / descending movement in front of the ascending / descending member 25. A compression spring 35 is provided between the upper end of the guide plate 32 and the lower surface of the bracket 31 and the guide plate 32 has a downwardly directed force by the compression spring 35.

The lower end of the guide plate 32 is disposed below the bottom surface of the movable heater 26 attached to the lower end of the ascending / descending member 25 and is lowered ahead of the movable heater 26 when descending for sealing, . This is also the case when an obstacle such as a finger is placed on the tip of the waterproof pack which has entered the inlet 21.

The top dead center of the guide plate 32 is the time when the upper end of the active hole 34 touches the guide shaft 33 and the bottom dead point is when the lower end of the active hole 34 is blocked by the guide shaft 33.

The cushion members (36) and (37) are attached to the lower end of the guide plate (32) and the bottom surface of the loading port (21) to elastically sandwich the contents held therebetween.

FIG. 6 shows a fusion state when the waterproof package is normally inserted.

That is, when the waterproof pack 40 is pushed into the inlet 21 of the apparatus, the lifting and lowering body 25 descends smoothly to the bottom dead point and the movable heater 26 causes the waterproof pack 40, which is placed on the fixed heater 25, The portion of the inlet 41 of the heating plate 40 is heated and pressed. At this time, since the upper end of the safety plate 32 is positioned under the sensor hole 29, the sensor hole 29 is not blocked and is not recognized as an obstacle, so that the sensor 30 and the fusing device operate normally.

Since the safety plate 32 provided in front of the ascending / descending member 25 is operated in conjunction with the ascending / descending member, only the safety plate 32 is configured to be able to move up and down independently, The lower end touches the upper surface of the waterproof case 40 one step ahead of the ascending / descending member 25 and helps the movable heater 26 to be pressed correctly.

7 and 8 show a case in which the fusing device is lowered in a state in which the hand of the user pushing the waterproof pack is deeply inserted into the slot (image is formed in the conventional structure) However, if a finger is placed thereon, the lower end of the safety plate 32, which is accompanied with the ascending / descending member 25, first touches the finger as shown in FIG. The lift plate 32 stops lowering due to the resistance of the finger and the lift member 25 urged by the stepping motor 28 is moved in a direction corresponding to the height difference between the bottom surface of the movable heater 26 and the lower end of the safety plate 32 Continue descending. In other words, the safety plate 26 is blocked by the finger and is pushed up.

Then, the top surface of the safety plate 32 appears in front of the sensor 30, and if obstructed, it is recognized as an obstacle. The sensor 30 senses the fact that an obstacle has appeared in front, and the sensing signal is immediately applied to the step motor 28 to drive it inversely. As soon as the stepper motor 28 is reversely driven, the ascending / descending member 25 is switched to the ascending mode before the movable heater 26 touches the fingers to lead the safety plate 32 to ascend and return straight. Therefore, it prevents finger burns and keeps safety.
