[0035] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0036] Reference Figure 1 , shows a schematic diagram of a transmission device of this embodiment, such as Figure 1 As shown, the transmission device includes: a accommodating mechanism 1, a first rotating mechanism 2 and a second rotating mechanism 3; the accommodating mechanism 1 includes a notch 13, the accommodating mechanism 1 is used to accommodate items, and the notch 13 is used for items to enter or exit the accommodating mechanism 1; the accommodating mechanism 1 is connected to the first rotating mechanism 2 and the second rotating mechanism 3, the first rotating mechanism 2 is used to adjust the inclination angle of the accommodating mechanism 1 in the left-right direction, and the second rotating mechanism 3 is used to adjust the inclination angle of the accommodating mechanism 1 in the front-back direction.

[0037] In this embodiment, the accommodating mechanism 1 can be used to accommodate items, such as drinks or food, and the accommodating mechanism 1 can be connected to the first rotating mechanism 2 and the second rotating mechanism 3, so that the accommodating mechanism 1 can rotate left and right, or forward and backward. By adjusting both at the same time, the accommodating mechanism 1 can be rotated in any direction, which is convenient for adjusting the position of the items in the accommodating mechanism 1, so that the staff can easily complete the sorting and replenishment operations, improve the efficiency of replenishment and sorting, and save a lot of manpower and material resources.

[0038] Further, refer to Figure 2 , shows a schematic diagram of a transmission device of this embodiment, such as Figure 2 As shown, the accommodating mechanism 1 includes a box-shaped body 11 and an auxiliary moving component 12. The auxiliary moving component 12 is arranged at the bottom or side of the box-shaped body 11 to reduce the friction between the items and the bottom or side of the box body, thereby facilitating the movement of the items.

[0039] The structural composition of the accommodating mechanism 1 may include a box-shaped body 11 and an auxiliary moving component 12, wherein the box-shaped body 11 includes notches 13 arranged at different positions, and the functions of each notch 13 are different; in addition, the auxiliary moving component 12 can be arranged at the bottom or side of the box-shaped body 11. The function of the auxiliary moving component 12 is to assist items to enter the accommodating mechanism 1 through the notch 13 or to assist items to move in the accommodating mechanism 1. The structure is simple and easy to implement. When the first rotating mechanism 2 and the second rotating mechanism 3 start to move, the auxiliary items move in the accommodating mechanism 1.

[0040] In practice, the auxiliary moving component 12 can be arranged at the bottom or on the four sides, and this embodiment does not impose any restrictions on this. As for the specific structure of the auxiliary moving component 12, it can be a non-powered roller structure or a pulley structure, so as to reduce the friction of the items in the storage mechanism 1 and assist the movement of the items in the storage mechanism 1. This embodiment does not impose too many restrictions on the specific structure of the auxiliary moving component 12.

[0041] Specifically applied to this embodiment, Figure 2 As shown, a notch 13 is provided on the front of the box-shaped body 11 of the accommodating mechanism 1, and the accommodating mechanism 1 is connected to the cargo aisle 7 through the bottom of the notch 13, and the cargo aisle 7 is used to place items; the notch 13 is also provided on the side of the box-shaped body 11 for taking out or putting in items.

[0042] Furthermore, the front and side surfaces of the box-shaped body 11 of the accommodating mechanism 1 are provided with notches 13. The front notch 13 is used for items to enter or exit the cargo channel 7; and the side notch 13 is used for staff to take out or put in items.

[0043] Reference Figure 3 , shows a schematic diagram of a blocking component 14 of this embodiment, such as Figure 3 As shown, the accommodating mechanism 1 includes a blocking component 14, and the blocking component 14 is movably connected to the accommodating mechanism 1, and is used to close any one or two gaps 13 on the front side of the box-shaped body 11 in the accommodating mechanism 1;

[0044] The blocking component 14 includes a first synchronous pulley 141, a second synchronous pulley 142, a synchronous belt 143, a fixing member 144 and a blocking plate 145; the first synchronous pulley 141 and the second synchronous pulley 142 are arranged on the top of the box-shaped body 11 of the accommodating mechanism 1; the synchronous belt connects the first synchronous pulley 141 and the second synchronous pulley 142; the fixing member 144 is fixed on the synchronous belt 143, and the fixing member 144 is connected to the blocking plate 145;

[0045] When the first synchronous pulley 141 and the second synchronous pulley 142 drive the synchronous belt 143 to move, the blocking plate 145 is driven to move through the fixing member 144, thereby closing any one or two gaps 13 on the front side of the accommodating mechanism 1.

[0046] In actual application in this embodiment, the blocking component 14 can close one or two gaps 13 on the front side of the accommodating mechanism 1. Figure 1 As shown, the blocking component 14 closes the gap 13 on the right side of the front. Combined with the above structure, the specific working principle of the transmission device is as follows: when the article enters the storage mechanism 1 from the gap 13 on the left side of the front, the first rotating mechanism 2 and the second rotating mechanism 3 are controlled to rotate rightward and forward, so that the article moves to the front right side of the storage mechanism 1 through the auxiliary moving component 12, and the blocking component 14 closes the gap 13 on the right side of the front, preventing the article from sliding out of the storage mechanism 1.

[0047] Reference Figure 4 , shows a schematic diagram of a transmission device of this embodiment, such as Figure 4 As shown, the transmission device includes a two-axis four-way moving mechanism 4, and the accommodating mechanism 1 is connected to the two-axis four-way moving mechanism, and the two-axis four-way moving mechanism is used to move the accommodating mechanism 1 in the up and down direction or the left and right direction perpendicular to the ground.

[0048] Specifically, the dual-axis four-way moving mechanism includes a first slide rail 41, a second slide rail 42 and a main slide rail 43. The first slide rail 41 and the second slide rail 42 are arranged to slide and parallel, and the main slide rail 43 is arranged between the first slide rail 41 and the second slide rail 42; the accommodating mechanism 1 includes a main slide rail 43 connecting piece; a sliding block is arranged on the main slide rail 43; the accommodating mechanism 1 is connected to the sliding block through the main slide rail 43 connecting piece; the main slide rail 43 moves between the first slide rail 41 and the second slide rail 42, so that the accommodating mechanism 1 moves in the up and down direction or the left and right direction perpendicular to the ground.

[0049] In this embodiment, the transmission device can be used in vending machines with multi-layer aisles 7, that is, the accommodating mechanism 1 can be moved to any position in a plane perpendicular to the ground through the dual-axis four-way moving mechanism, thereby improving the replenishment efficiency. The dual-axis four-way moving mechanism can include a first slide rail 41, a second slide rail 42 and a main slide rail 43, which are in the shape of an "I". The main slide rail 43 slides between the first slide rail 41 and the second slide rail 42, and the accommodating mechanism 1 slides along the length direction of the main slide rail 43, so that the accommodating mechanism 1 can be moved to any position in the plane, thereby improving the replenishment efficiency.

[0050] Reference Figure 5 , shows a partial schematic diagram of a transmission device of this embodiment, such as Figure 5 As shown, the first rotating mechanism 2 includes a first bevel gear 21, a second bevel gear 22, a first rotating shaft 23 and a first rotating shaft connecting member 24; the first bevel gear 21 and the second bevel gear 22 cooperate with each other, the first rotating shaft 23 is fixed to the center of the second bevel gear 22, the first rotating shaft 23 is connected to the first rotating shaft connecting member 24, and the first rotating shaft connecting member 24 is connected to the protrusion of the box-shaped body 11;

[0051] When the first bevel gear 21 rotates, the first rotating shaft 23 and the first rotating shaft connecting member 24 are driven to rotate leftward or rightward through the second bevel gear 22, so that the accommodating mechanism 1 rotates leftward or rightward.

[0052] In this embodiment, the first bevel gear 21 can be connected to a motor, and the motor is used as a power source to control the rotation of the first bevel gear 21. Because the entire box-shaped body 11 and the second rotating mechanism 3 are connected to the first rotating mechanism 2, when the first rotating shaft 23 and the first rotating shaft connecting member 24 rotate to the left or right, the box-shaped body 11 and the second rotating mechanism 3 will also rotate to the left or right, thereby causing the accommodating mechanism 1 to rotate to the left or right.

[0053] On the other hand, the second rotating mechanism 3 includes a third bevel gear 31, a fourth bevel gear 32, a second rotating shaft 33 and a second rotating shaft connecting member 34; the third bevel gear 31 and the fourth bevel gear 32 cooperate with each other, the second rotating shaft 33 is fixed to the center of the fourth bevel gear 32, the second rotating shaft connecting member 34 is fitted with the protrusion 14 of the box-shaped body 11, and the second rotating shaft 33 passes through the second rotating shaft connecting member 34 and the protrusion of the box-shaped body 11;

[0054] When the third bevel gear 31 rotates, the second rotating shaft 33 is driven to rotate forward or backward through the fourth bevel gear 32, so that the accommodating mechanism 1 rotates forward or backward.

[0055] The second rotating mechanism 3 is independent of the first rotating mechanism 2 and is used to control the accommodating mechanism 1 to rotate forward or backward; the second rotating shaft 33 passes through the second rotating shaft connecting member 34 and the protrusion of the box-shaped body 11; the third bevel gear 31 is controlled to rotate by a motor, and when the third bevel gear 31 rotates, the second rotating shaft 33 is driven to rotate through the fourth bevel gear 32, thereby causing the accommodating mechanism 1 to rotate forward or backward; the structure is simple, and the accommodating mechanism 1 can rotate in any direction.

[0056] Reference Figure 6 and 7 , shows a schematic diagram of a transmission device of this embodiment, such as Figure 6 and 7 As shown, the accommodating mechanism 1 also includes a rotating flat plate component 66, and the rotating flat plate component 6 is arranged below the notch 13 of the accommodating mechanism 1, and the accommodating mechanism 1 is connected to the cargo aisle 7 through the rotating flat plate component 6; the rotating flat plate component 6 includes a protrusion; the cargo aisle 7 includes a limiting component; when the rotating flat plate component 6 is connected to the cargo aisle 7, the protrusion of the rotating flat plate component 6 presses the limiting component downward, so that the items enter the accommodating mechanism 1 from the cargo aisle 7 through the notch 13 via the rotating flat plate component 6; or the items exit from the notch 13 of the accommodating mechanism 1 to the cargo aisle 7 via the rotating flat plate component 6.

[0057] In this embodiment, the accommodating mechanism 1 may include a rotating flat plate component 6, the rotation of which is controlled by a motor so that it can be folded up or lowered, and can be connected to the cargo aisle 7 when lowered; specifically, through the cooperation of the protrusion on the rotating flat plate component 6 and the limiting component on the cargo aisle 7, the items in the cargo aisle 7 can enter the accommodating mechanism 1.

[0058] As for the type of the cargo lane 7, it can be any one of a spring spiral cargo lane 7, a crawler cargo lane 7, and an inclined cargo lane 7, and this embodiment does not impose too many restrictions on this.

[0059] Taking the replenishment operation as an example, when the blocking component 14 closes the gap 13 on the right side of the front, the staff puts the article 8 into the accommodating mechanism 1 through the side gap 13 (it should be noted that the articles in the cargo aisle 7 can also be received from the gap 13 on the front), and controls the first rotating mechanism 2 and the second rotating mechanism 3 to rotate rightward and forward, and the article is moved to the right side inside the accommodating mechanism 1 via the auxiliary moving component 12. At this time, the blocking component 14 is moved to open the gap 13 on the left side of the front of the accommodating mechanism 1, and the rotating flat plate component 6 is lowered. The protrusion of the rotating flat plate component 6 presses the limiting component downward, and the accommodating mechanism 1 is controlled to rotate backward. At this time, the article exits from the gap 13 of the accommodating mechanism 1 via the rotating flat plate component 6 to the cargo aisle 7, completing the replenishment operation and improving the replenishment efficiency.

[0060] Furthermore, taking the sorting operation as an example, the complete working principle of the transmission device is explained: first, the purpose of the physical and chemical operation is to move the items 8 with a late production date to the front of the aisle, and to add the items 8 with an early production date to the back of the same aisle, so that the items 8 with a late production date can be sold as soon as possible. Through the above-mentioned replenishment operation principle, the items with a late production date in a certain aisle are moved to the accommodating mechanism 1, and then the items with a late production date are moved to another aisle through the accommodating mechanism 1, and then the items with an early production date are added to the back of the first aisle through the above-mentioned replenishment operation principle. Finally, the items with a late production date in the second aisle are moved to the front of the first aisle through the accommodating mechanism 1, thereby improving the physical and chemical efficiency.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
