Since the cover to be opened or closed is the outer cover 21, the outer cover 21 and the inner cover 22 can be regarded as a single cover and defined as a first cover. In the embodiment shown in FIG. 1, the interference member 101 forms an interference with the outer cover 21. For example, the outer cover 21 includes at least one groove 211, and the interference member 101 includes at least one protrusion 101a. When the protruding portions 101a of the interference member 101 are fitted into the grooves 211 of the outer cover 21, they interfere with each other. It will be understood that those skilled in the art to which the present invention pertains can adapt the design of the interference member 101 to the outer shape of the cover to interfere with the cover of the container.

The rotating shaft 102 is coupled to the interference member 101 to drive the interference member 101 to rotate. It can be understood that when the interference member 101 forms an interference with the outer cover 21, the rotation of the rotating shaft 102 to drive the interference member 101 can also drive the outer cover 21 to rotate. In an embodiment, the interference member 101 is connected to the rotating shaft 102 in a replaceable manner, so that the corresponding interference member 101 can be replaced with the cover of different outer shapes. For example, the interference member 101 is locked to the rotating shaft 102 by a screw 101b. It should be noted that the rotating shaft 102 includes a passage 102a, wherein one of the first openings of the passage 102a faces the cover 20a, and at least one second opening of the passage 102a is disposed at a side wall of the rotating shaft 102. When the air extracting device 103 is connected to the second opening of the passage 102a for pumping, the pressure in the passage 102a is lowered, and the cover 20a is sucked by the first opening of the passage 102a.

Referring to FIG. 1 , in an embodiment, the automatic switch cover device 10 of the present invention may include a sleeve 104 that is sleeved on the rotating shaft 102 , wherein the rotating shaft 102 is rotatable relative to the sleeve 104 . An air extraction space is defined between the sleeve 104 and the rotating shaft 102, wherein the sleeve 104 is provided with a suction hole 104a. According to this result, the suction space between the sleeve 104 and the rotating shaft 102 can communicate with the suction hole 104a on the sleeve 104 and the second opening of the passage 102a. The air extracting device 103 connects the air vent 104a on the sleeve 104 to evacuate the passage 102a in the rotating shaft 102.

In an embodiment, as shown in FIG. 1, the automatic switch cover device 10 of the present invention may include an annular airtight member 105 disposed around the first opening of the passage 102a, thereby increasing the air between the rotating shaft 102 and the cover 20a.

Following the above description, the pressure detector 106 is connected between the channel 102a of the rotating shaft 102 and the air extracting device 103 to detect the pressure change of the channel 102a. Depending on the pressure change of the passage 102a, it can be judged whether or not the interference member 101 has moved to an appropriate position or whether the cover 20a has been adsorbed. For example, when the annular airtight member 105 contacts the cover body 20a, the first opening of the passage 102a becomes a closed state, and in the case where the air extracting device 103 continues to pump, the pressure in the passage 102a will rapidly drop, so It can be known that the interference member 101 has moved to an appropriate position. Alternatively, when the interference member 101 rotates the cover 20a, the annular airtight member 105 does not contact the cover 20a. When the lid body 20a is continuously rotated to be separated from the container 200, the lid body 20a is adsorbed by the pressure difference, and the first opening of the passage 102a is closed. It is known that the cover 20a has detached from the container 200 when it is detected that the pressure in the passage 102a drops rapidly.

The lifting device 107 is coupled to the interference member 101 and the rotating shaft 102 to drive the interference member 101 and the rotating shaft 102 to move in a lifting direction. For example, when the cover 20a has been detached from the container 200 and is adsorbed, the lifting device 107 can drive the interference member 101 and the rotating shaft 102 away from the container 200 to remove the cover 20a. Alternatively, when the cover is to be opened, the interference member 101 and the rotating shaft 102 are moved toward the container 200 to approach the cover 20a, and the interference member 101 is interfered with the cover 20a.

The motor 108 is coupled to the rotating shaft 102 to drive the rotating shaft 102 and the interference member 101 to rotate, thereby rotating the cover 20a. In one embodiment, the motor 108 can be a servo motor. In one embodiment, the motor 108 is coupled to the rotating shaft 102 via a reducer 108a and a coupling 108b. The structure and function of the reducer 108a and the coupling 108b are well known to those skilled in the art, and will not be described herein. The controller 109 is electrically connected to the pressure detector 106, the lifting device 107, and the motor 108. The controller 109 can determine the current operating state according to the pressure change of the passage 102a outputted by the pressure detector 106, thereby controlling the rotation speed or the rotation direction of the motor 108 and the ascending or descending of the lifting device 107.

Referring to FIG. 2, in an embodiment, the automatic switch cover device 10 of the present invention includes an image sensor 110 and a mobile device that are electrically connected to the controller 109, respectively. The image sensor 110 is used to capture an image of one of the containers 200. The controller 109 can adjust the relative position of the interference member 101 and the cover 20a of the container 200 according to the positioning image captured by the image sensor 110 to align the interference member 101 and the cover 20a. For example, the mobile device includes a track 111a and a track 111b. The interference member 101 is movable left and right along the rail 111a, and further, the rail 111a is movable back and forth along the rail 111b. According to this configuration, the interference member 101 can be moved to any position parallel to the paper surface.

In one embodiment, the mobile device includes a transport mechanism 120 and a fixture 121. The transport mechanism 120 can move the container 200 into the range of the track 111a and the track 111b, and the fixture 121 can hold the container 200 in a predetermined position. In one embodiment, the mobile device can include at least one roller 122. For example, the roller 122 is coupled to the fixing member 121, and the roller 122 abuts against the container 200 when the fixing member 121 holds the container 200. The roller 122 can drive the container 200 to rotate, so that the cover 20a of the container 200 is rotated to a set position. In other words, the rotation of the container 122 by the roller 122 can also adjust the relative position of the interference member 101 and the cover 20a. It can be understood that the operation of the mobile device can be achieved by partially omitting the track 111a, the track 111b, the conveying mechanism 120 or the fixing member 121 according to actual design requirements.

In the embodiment shown in Fig. 1, the cover to be unscrewed is the outer cover 21 of the cover 20a, which is locked to the container 200. Fig. 3a shows a three-dimensional structure of the cover body 20b; Fig. 3b shows a partial sectional structure of the automatic switch cover device according to another embodiment of the present invention, and a sectional structure of the cover body 20b along the line BB. Referring to FIG. 3, in an embodiment, the cover to be unscrewed is the cover 20b inner cover 22 (defined herein as a first cover), which is locked to the outer cover 21 (here defined as the second On the cover). Therefore, when the interference member 101 is inserted into the recess 221 of the inner cover 22 to interfere with the inner cover 22 and rotate the inner cover 22, the outer cover 21 may also rotate to be separated from the container 200. In order to avoid this, in an embodiment, referring to FIG. 3, the automatic switch cover device of the present invention further includes a stopper 130 disposed on a radially outer side of the interference member 101. According to this configuration, when the interference member 101 forms an interference with the inner cover 22 and rotates, the stopper 130 abuts against the outer cover 21 and restricts the rotation of the outer cover 21. In an embodiment, the stopper 130 can be an elastic material. For example, the stop 130 can be a rubber material.

In one embodiment, the automatic switch cover device of the present invention includes a cushioning mechanism in which the stop member 130 is coupled to the cushioning mechanism. According to this configuration, the cushioning mechanism can adaptively adjust the force of the stopper 130 against the outer cover 21. For example, the cushioning mechanism includes a base 131 and at least one resilient element 132, such as a spring. The stopper 130 is disposed on the base 131. According to this configuration, when the stopper 130 abuts against the outer cover 21, the elastic member 132 is pressed, and the restoring force of the elastic member 132 causes the stopper 130 to generate sufficient force to restrict the rotation of the outer cover 21.

In summary, the automatic switch cover device of the present invention interferes with the cover of the container by the interference member, rotates the interference member to rotate the cover body, and suctions the cover body by vacuum suction and removes the cover body. Therefore, the automatic switch cover device of the present invention can be opened and closed in a mechanically automated manner to prevent a person from entering a high-risk working area when taking or recycling chemicals, thereby reducing the casualties of the operator during accidents. .
