[0053] The automatic bag stacking device in this embodiment is equipped with double emergency stop buttons on the outside, which are used to stop the device in an emergency. The automatic bag stacking device in this embodiment is also equipped with a buzzer alarm system, which is used to alarm in an emergency. It also has an alarm light, which has red and green colors. Green means the device can run, and red means it cannot run.

[0054] In summary, the finished bag 01 is first placed on the conveying mechanism 2. According to the position of the finished bag 01 and the position of the valve 01, the detection mechanism 5 is operated to rotate the adjusting wheel 515, and the rotating shaft 513 rotates. At the same time, the rotating shaft 513 moves along the rack 514 in the Y-axis direction, driving the mounting plate 55 to move along the Y-axis direction, thereby adjusting the position of the sensor 56 in the Y-axis direction, so that the sensor 56 can correctly sense the position of the valve 02.

[0055] Then rotate the adjustment handle 411 to adjust the position of the adsorption component 42 in the X-axis direction, so that the vacuum suction cup 4200 is offset from the position of the valve 02 in the X-axis direction, and does not collide with the valve 02 when descending. Drive the motor 3112, the motor 3112 drives the slide 3113 to move in the Y-axis direction, and drives the installation cross bar 35 to move along the Y-axis direction, thereby adjusting the position of the adsorption component 42 in the Y-axis direction, so that the adsorption component 42 is located above the rotating shaft 511.

[0056] The finished product bag 01 is conveyed along the Y-axis direction at a set speed on the conveying plane of the conveying mechanism 2. When the sensor 56 detects that the valve 02 is conveyed above the rotating shaft 511, the telescopic rod 421 is driven to drive the vacuum suction cup group 420 to move downward along the Z-axis direction until the suction cup body 4202 contacts the finished product bag 01, and the vacuum pump is started to suck, so that negative air pressure is generated in the suction cup body 4202, thereby firmly sucking the finished product bag 01, and the finished product bag 01 can be started to be transported. When the finished bag 01 is transported to the right place, air is steadily inflated into the suction cup body 4202, so that the negative air pressure in the suction cup body 4202 changes to zero pressure or slightly positive air pressure, and the suction cup body 4202 is separated from the finished bag 01, thereby completing the transport of the finished bag 01. The above operation is repeated by setting the adsorption component 42 to transport the finished bag 01 along the Y-axis at different distances, so that the valve 02 of the finished bag 01 transported last time will not overlap when the finished bag 01 is transported to the right place next time, so that the finished bag 01 can be better stacked and convenient for subsequent folding operations, thereby realizing automatic stacking of the finished bag 01, greatly saving manpower and improving the efficiency of the production line.
