The external surface of cabinet, cabinet body top and bottom all set up the track, set up sliding parts such as pulley on the first goods transfer device, after receiving the start command, the controller in the accommodation space starts the motor work that is used for controlling first goods transfer device position change in the first goods transfer device, controls first goods device and slides along predetermineeing track side by side or slide the access & exit department to appointed storehouse from top to bottom, and first goods transfer device receives the drive back along cabinet body surface up-and-down motion or left and right movement to the access & exit department of appointed storehouse (say 3 rd row 2 nd storehouse) to carry out the packing box access. The container is herein, for example, a meal box, which contains food, beverages, etc.
In one embodiment, when an external cargo box is required to be delivered into the cargo compartment of the cabinet for storage, as shown in fig. 3, the first cargo transferring device 40 carries the cargo box 50 thereon, and the bottom of the cargo box 50 is provided with a rack, and the rack is engaged with teeth on the outer surface of the first driving member of the first cargo device 40, and is driven by the first driving member to move forward (in the direction approaching the cargo compartment).
According to the above-mentioned up-down movement or left-right movement process, the first cargo transferring device 40 moves to the designated warehouse entrance, the second cargo transferring device 30 is arranged at the designated warehouse entrance, and the outer surface of the first follower of the second cargo transferring device 30 is also toothed, so that the first driving member moves, the tooth of the first driving member is meshed with the tooth of a linkage gear 70 to drive the linkage gear 70 to move, and the tooth of the linkage gear 70 is meshed with the tooth of the first follower to drive the first follower to move in the same direction.
As shown in fig. 3, fig. 3 is divided into an upper part and a lower part, wherein the upper part is a state that the container is outside the cargo compartment, and the lower part is a state that the container is transported into the cargo compartment. As can be seen from fig. 3, the cargo box 50 on the first cargo transferring device 40 is moved from the first cargo transferring device 40 on the left side to the second cargo transferring device 30 on the right side, i.e. from outside the cargo box to inside the cargo box, under the cooperation and driving of the first driving member and the first driven member.
In order to reduce the power source, in the embodiment of the application, only the first driving member is connected with the motor to be used as a driving gear, and in order to ensure the directionality and the accuracy of the gear transmission, as described above, the container transporting system of the embodiment further comprises a linkage gear 70,
Referring to fig. 3, the outer surface of the first driving member 401 and the outer surface of the first driven member 301 are in indirect meshing transmission through the linkage gear 70;
Referring to fig. 4 and 7, the first follower 301 is mounted at the designated warehouse entrance through a first shaft (not shown in fig. 4), one end of the first shaft is connected to a first connecting hole 602 located at one end of the first rocker arm 60, the other end of the first shaft is connected to a second connecting hole 603 located at one end of the second rocker arm, and the first rocker arm 60 and the second rocker arm are respectively disposed at the left and right sides of the designated warehouse entrance;
The other end of the first rocker arm 60 has a third connecting hole (see hole connected to the shaft 703 at one end of the link gear in fig. 7), and the other end of the second rocker arm has a fourth connecting hole (see hole connected to the shaft 704 at one end of the link gear in fig. 7).
Referring to fig. 8, two ends of the linkage gear 70 are respectively provided with a first mounting shaft 703 and a second mounting shaft 704, the first mounting shaft 703 is matched with the third connecting hole, and the second mounting shaft 704 is matched with the fourth connecting hole, so that the linkage gear 70 is connected with a designated warehouse.
With continued reference to fig. 8, the linkage gear 70 has a cylindrical body 701 in the middle, cones 702 at the left and right ends,
The outer surface of the cylinder 701 of the linkage gear 70 is tooth-shaped; since the modulus of the linkage gear is indefinite, the provision of both the cylinder and the cone in the tooth form greatly increases the manufacturing cost, and since the cylinder portion is a portion directly connected to the first driven member and the first driving member, this portion is provided in the tooth form, and the cone portion is not engaged with the first driven member and the first driving member, the provision of the tooth form is unnecessary, so that the manufacturing cost can be reduced.
The length of the cylinder 701 of the linkage gear 70 is greater than or equal to the sum of the lengths of the cones 702.

It should be noted that, in practical application, when the storehouse inner space is limited, in order to simplify transfer device's structure, first follower can only include a set of driven double gear structure, and this set of driven double gear structure is located the access & exit department of appointed storehouse, as long as can dock the meshing with first driving piece for receive and drive the packing box motion to in the storehouse.
In order to improve transmission precision and efficiency, a plurality of groups of driven double-gear structures shown in fig. 6 are connected through a synchronous belt.
