The stop pin 142 is small in size, so that the insertion arrangement is convenient, and the overall design difficulty is reduced; meanwhile, the number of the stop pins 142 can be flexibly set so as to provide stable and reliable supporting force, and the embodiment adopts two stop pins 142 to respectively form supports at two sides of the lower part of the heat-seal connecting part 420, so as to prevent the cover body 400 from inclining in the cover falling channel 111.

In some embodiments, the second lateral stop mechanism 150 can be configured as shown in fig. 4 and 5. Referring to fig. 4 and 5, the second transverse stopping mechanism 150 includes a second stopping controller 151 and a stopping piece 152, the second stopping controller 151 has a telescopic end moving along a third horizontal path, the stopping piece 152 is connected to the telescopic end of the second stopping controller 151, and the stopping piece 152 forms a second stopping end. The stopping piece 152 is provided with a clearance gap corresponding to the lifting clamping jaw 132, so that the lifting clamping jaw 132 can be lifted above the stopping piece 152 in a state that the stopping piece 152 is reset to facilitate next clamping, and it should be noted that the clearance gap should not be too large in opening area because the stopping piece 152 needs to keep effective support for the cover body 400.

Some embodiments employ the structure shown in fig. 1, 4 and 8. Referring to fig. 1, 4 and 8, a monitoring notch 112 is formed in the top of the sidewall of the cap falling support 110, a first sensor 160 is disposed at the monitoring notch 112, the first sensor 160 is used to monitor whether a cap 400 is present at the top of the cap falling passage 111, if no cap 400 is present, a command is fed back to the control unit, the control unit controls the upstream cap supplying unit to supply a new cap 400, and the cap falling passage 111 is always kept filled with the cap 400, so as to maintain the capping continuity.

Some embodiments employ the structure shown in fig. 9-11. Referring to fig. 9 to 11, a second sensor 330, a third sensor 340 and a fourth sensor 350 (shown as a single dashed line in fig. 9) are further disposed on one side of the clamping mechanism 320, and the second sensor 330, the third sensor 340 and the fourth sensor 350 are all photoelectric sensors. The second sensor 330, the third sensor 340 and the fourth sensor 350 are respectively used for sensing different corner regions of the heat-sealing connection portion 420, when one or more of the sensors are not triggered, it is determined that the position of the cover 400 is deflected or the cover 400 is not placed, at this time, the control unit controls the steering mechanism 310 to drive the clamping mechanism 320 to rotate to a third state in a direction away from the sealing unit 240, the clamping mechanism 320 is released, so that the cover 400 with an unqualified placement posture falls into the recovery unit (or the cover 400 is released in a state without the cover 400), and the cover 400 is conveyed to the cover arranging unit again for arrangement.

On the plane of the two extending sides of the heat-sealing joint 420, the orthographic projection of the heat-sealing joint 420 is rectangular, the second sensor 330, the third sensor 340 and the fourth sensor 350 respectively correspond to three corners of the rectangular outline, and the signal transmission paths of the second sensor 330, the third sensor 340 and the fourth sensor 350 are all parallel to the central axis of the sleeve shaft 311. The cover body 400 falls in the cover falling channel 111 in a posture in which the mouth portion 410 faces downward and the heat-seal connecting portion 420 faces upward, and when the mouth portion 410 of the cover body 400 is held by the holding mechanism 320, if the cover body 400 is in a standard posture (as shown in fig. 9, in the standard posture, the plane on which the two extending sides of the heat-seal connecting portion 420 are located is perpendicular to the central axis of the sleeve shaft 311), it is defined that in this state, the projection of the heat-seal connecting portion 420 on the plane on which the two extending sides of the heat-seal connecting portion 420 are located is a standard contour line, which is shown by a broken line in fig. 10 and 11. The specific working principle is roughly divided into the following three cases:

1) Under the condition that the cover 400 falls in a standard non-attitude (or similar to the standard attitude), when the mouth 410 is clamped by the clamping mechanism 320, the deflection exceeding the preset range does not occur, on the plane where the two extending sides of the heat-sealing connecting part 420 are located, the orthographic projection contour of the heat-sealing connecting part 420 basically conforms to the standard contour line, and the second sensor 330, the third sensor 340 and the fourth sensor 350 are not triggered, at this time, the posture of the cover 400 in the clamping mechanism 320 is judged to be correct, the operation of switching from the first state to the second state can be performed, and the control unit controls the steering mechanism 310 to drive the clamping mechanism 320 to clockwise rotate towards the sealing unit 240 side to the second state; after the heat-seal connecting portion 420 is butted against the bag opening, the first heat-seal member 220 and the second heat-seal member 230 move towards each other and clamp the butted portion for heat-sealing, and then the clamping mechanism 320 is released and returns to the first state to wait for the next clamping rotation.

2) After the mouth 410 is clamped by the clamping mechanism 320, if the cover 400 is in the non-standard posture similar to that of fig. 10, the cover 400 rotates along the axis of the cover 400 to deviate from the predetermined posture, so that the orthographic projection profile does not conform to the standard contour line, at this time, although the orthographic projection profile is still rectangular, the corner already deviates from the corner of the standard contour line, the level signals of the second sensor 330 and the third sensor 340 are changed, at this time, it is determined that the posture of the cover 400 in the clamping mechanism 320 is incorrect, and an operation of switching from the first state to the third state can be performed, that is, the control unit controls the steering mechanism 310 to drive the clamping mechanism 320 to rotate in the direction away from the sealing unit 240 to the third state, the clamping mechanism 320 is released, so that the cover 400 with the unqualified posture is dropped into the recovery unit (or released in the state without the cover 400), and the cover 400 is conveyed into the cover sorting unit again.

3) After the clamping mechanism 320 clamps the mouth 410, if the cover 400 is in the non-standard posture similar to that of fig. 11, the cover 400 deflects along the direction parallel to the axis of the sleeve shaft 311 to deviate from the predetermined posture, so that the orthographic projection profile does not conform to the standard contour line, at this time, although the orthographic projection profile is still rectangular, the corner already deviates from the corner of the standard contour line, so that the level signals of the second sensor 330, the third sensor 340 and the fourth sensor 350 are changed, and then it is determined that the posture of the cover 400 in the clamping mechanism 320 is incorrect, the control unit controls the steering mechanism 310 to drive the clamping mechanism 320 to rotate to the third state in the direction away from the sealing unit 240, the clamping mechanism 320 is released, so that the cover 400 with the unqualified placement posture falls onto the recycling unit (or releases the cover 400), and the cover 400 is transferred to the cover arranging unit again for carrying out again.
