The load element 22 is moved or released, wherein when the switching actuator 23 releases the load element 22, it will cause the load element 22 to be unconstrained and fall in a free fall manner.

In addition, the switching actuator 23 drives the load cell 22 to move the package 100 to a first position, and when the switching actuator 23 reaches the first position, the load element 22 is released, thereby causing the load element 22 to fall in a free fall manner. And the package 100 is moved to a second position.

As shown in FIG. 2 to FIG. 4, the sensor structure 20 performs a sealing test on the package 100 to generate a test signal. Further, as described below, the sensor 24 is mounted on the load element 22 and follows the load element 22 to move. The signal includes a first signal and a second signal.

Wherein, the present sensor 24 has two embodiments. The first embodiment of the sensor 24 is, for example, the sensor 24 is a distance sensor for detecting the current position, and the step d is switched. When the actuator 23 is in the first position, the load element 22 is released for a predetermined time, so that the load element 22 falls in a free fall manner after the preset time has elapsed and the package 100 is moved to the second position, and the distance sensor is used for detecting The amount of displacement change from the first position to the second position, the distance sensor may be an infrared sensor, an ultrasonic sensor or a laser light sensor.

In the first embodiment, after the preset time elapses, when the package 100 is in the sealed state, the air inside the package 100 is not able to be dissipated to the external environment, and the second position is limited downward, so the controller 25 calculates After the amount of displacement change from the first position to the second position is within the safe value, the controller 25 drives the prompter 25 to issue a prompt to seal the package 100.

On the contrary, after the preset time elapses, when the package 100 is in an unsealed state, the air inside the package 100 is pressed to the external environment, and the second position is moved downward, so the controller 25 calculates the first position. After the amount of displacement change to the second position is too large to exceed the safe value, the controller 25 drives the prompter 25 to issue a prompt that the package 100 is unsealed.

Second embodiment of the sensor 24, for example, the sensor 24 is a pressure sensor for detecting the reaction force of the package 100 to the load element 22, and the pressure sensor is fixed to the bottom surface 221 of the load element 22 and When the package 100 is able to be moved, the sensor 24 is sandwiched between the load element 22 and the package 100 in steps c and d, and the pressure sensor is used to detect the reaction force of the package 100 to the load element 22. The amount of change, the pressure sensor can be a membrane pressure sensor, a piezoelectric pressure sensor, a piezoresistive pressure sensor, or a capacitive pressure sensor.

In the second embodiment, after the preset time elapses, when the package 100 is in a sealed state, the air inside the package 100 is not pressed to the external environment, so that the air pressure inside the package 100 gives the reaction force of the load member 22. If the controller 25 calculates that the amount of change in the reaction force of the package 100 to the load cell 22 is greater than the set value, the controller 25 drives the prompter 25 to issue a seal indicating that the package 100 is sealed.

On the contrary, after the preset time elapses, when the package 100 is in an unsealed state, the air inside the package 100 is pressed to the external environment, so that the air pressure inside the package 100 gives the reaction force of the load element 22 less. Therefore, after the controller 25 calculates that the amount of change in the reaction force of the package 100 to the load cell 22 is less than the set value, the controller 25 drives the prompter 25 to issue a prompt that the package 100 is not sealed.

Thereby, the load element 22 moves the package 100 to the first position, and the first signal is generated when the sensor 24 reaches the first position, the load element 22 falls in a free fall manner and the package 100 is moved to the second position, and the sensing is performed. The second signal is generated when the device 24 is in the second position, and the controller 25 receives and calculates the first signal and the second signal, and then the driver prompter 26 issues a prompt to replace the conventional human mode detection by using an automated method, thereby enabling the inspection. Whether the package 100 is sealed or not has the advantages of saving manpower, reducing cost, increasing production rate, and detecting accuracy.

Referring to FIG. 5, another embodiment of the present invention relates to a sealed packaging apparatus 10. The embodiment of FIG. 5 is substantially the same as the embodiment of FIG. 4. The embodiment of FIG. 5 differs from the embodiment of FIG. 4 in a sealed package.
