In one embodiment of the present invention, preferably, as shown in fig. 1 to 3, the box member includes: a swing link 20, one end of which is rotatably provided on the mounting member 16; the stop lever 22 is connected with the other end of the swing rod 20, and the stop lever 22 is used for limiting the goods 10; the second driving part is connected with the swing rod 20 and is used for driving the swing rod 20 to rotate.

In this embodiment, it is specifically set that the box stopper includes the swing link 20, the lever 22, and the second driving portion. The swing rod 20 is rotatably arranged on the mounting piece 16, and the second driving part drives the swing rod 20 to rotate so as to drive the stop rod 22 connected with the swing rod 20 to rotate, thereby realizing limiting, avoiding or pushing the goods 10. The second driving portion may drive the swing rod 20 to rotate independently at this time, or may cooperate with the first driving portion to drive the swing rod 20 to rotate passively.

In this embodiment, the state in which the rotation center of the elastic member 24 with respect to the mount 16, the rotation center of the elastic member 24 with respect to the swing link 20, and the rotation center of the swing link 20 with respect to the mount 16 are collinear is set as the dead point state in which the position of the swing link 20 is set as the dead point position. Further, under the driving of the first driving member, when the swing rod 20 contacts with the first stop member 26 during the movement of the mounting member 16 in the direction of the entrance 122 of the cargo 10, the swing rod 20 rotates clockwise under the tensile force caused by the movement of the mounting member 16 and the interference of the first stop member 26, and after passing through the dead point position, the dead point state is released, at this time, the elastic member 24 releases the elastic force, and the swing rod 20 automatically keeps rotating clockwise under the action of the elastic force of the elastic member 24 until reaching the preset high point position. When the high point is preset, the swing rod 20 drives the stop lever 22 to be positioned above the goods 10. The stop lever 22 is rotated to a preset high-point position through a series of mechanical structures instead of electric control operation, so that the control process is simplified, and the position accuracy of the stop lever is improved. In addition, the second driving member does not need to be provided with an active driving device such as a motor, and two actions of movement and rotation of the swing rod 20 can be realized only by one motor in the first driving member, the elastic member 24, the first stop member 26 and other parts in the second driving member, so that the number of motors is reduced, the cost is reduced, and meanwhile, the control program is simplified.

In addition, the distance between the first preset position where the first stop piece 26 is located and the edge of the support frame 12, which is close to the direction where the outlet 124 of the cargo 10 is located, is smaller than or equal to the rotation radius of the stop lever 22, so that when the stop lever 22 rotates to the front of the cargo 10, that is, the front of the direction of the outlet 124 of the cargo 10, the stop lever 22 does not occupy too much position of the moving platform 14, but can well limit the cargo 10, and the cargo 10 is prevented from falling. Of course, the distance between the first preset position and the edge of the support frame 12 near the direction of the exit 124 of the cargo 10 may be larger than the rotation radius of the stop lever 22, and when the stop lever 22 rotates to the side of the direction of the exit 124 of the cargo 10, the stop lever 22 occupies the space above the moving platform 14, so as to occupy the space for placing the cargo 10.

Of course, the elastic member 24 may not be located on the center line of the swing link 20 with respect to the rotation center of the swing link 20. The elastic member 24 is located at one side of the swing rod 20, which is close to the interior of the swing rod 20, relative to the rotation center of the swing rod 20, and relative to the rotation center of the mounting member 16, so that the elastic member 24 can push the swing rod 20 to rotate, the length of the elastic member 24 can be shortened, the structure of the elastic member 24 is small, and the space occupation rate is reduced.
