Next, a specific structure of the plurality of beverage can storage bins 300 and a connection relationship between the respective components will be described.
As shown in fig. 2, a plurality of beverage can storage bins 300 are sequentially arranged along the edge of the outer rotating ring 212 of the buffer blanking drum 210; the beverage can storage bin 300 has a cylindrical structure, and the central axis of the beverage can storage bin 300 is parallel to the rotation axis of the buffer blanking drum 210. Specifically, the horizontal plane where the rotation axis of the buffer blanking drum 210 is located is taken as a separation plane, and the separation plane divides the buffer blanking drum to form an upper half area and a lower half area; a plurality of beverage can storage bins 300 are sequentially distributed along the edge of the buffer blanking drum 210 and are located in the upper half of the buffer blanking drum 210. In the present embodiment, the number of beverage can storage bins 300 is five.
As shown in fig. 8 and 9, each beverage can storage bin 300 has a beverage can receiving cavity 310, and a beverage can discharging hole 311 penetrating the beverage can receiving cavity 310 is formed in a bin wall of the beverage can storage bin 310; the beverage can discharging hole 311 is provided with a beverage can guiding pipe 320 (as shown in fig. 10), one end of the beverage can guiding pipe 320 is connected with the beverage can discharging hole 311, and the other end of the beverage can guiding pipe 320 is propped against the outer rotary ring 212.

Next, the operation principle of the above-described vending machine 10 having a plurality of independent storage bins will be described:
The beverage cans 20 stored in the beverage can accommodating cavity 310 are in a lying state, namely, the central axis of the cylindrical beverage cans 20 is parallel to the horizontal plane, so that on one hand, more beverage cans 20 can be stored by fully utilizing the space of the beverage can accommodating cavity 310, and on the other hand, the beverage cans 20 can be smoothly discharged from the beverage can discharging hole 311;
The plurality of beverage can storage bins 300 are sequentially distributed along the edge of the buffer blanking drum 210 and are positioned at the upper half area of the buffer blanking drum 210, and the beverage cans 20 in the beverage can accommodating cavity 310 can more easily come out from the beverage can discharging holes 311 and reach the beverage can guiding pipes 320 under the action of gravity;
When a consumer selects a certain type of beverage, the beverage can buffer blanking device 200 starts to work, specifically, the drum driving part 220 drives the buffer blanking drum 210 to rotate, so that the beverage can inlet and outlet 214 on the outer rotary ring 212 is communicated with the beverage can guiding pipe 320 at a certain beverage can storage bin 300; then, the beverage can shutter 330 is operated, that is, the shutter 332 is driven to retract by the shutter 331, so that the shutter 332 no longer intercepts the beverage can 20 at the beverage can guiding tube 320, and then the beverage can 20 slides along the beverage can guiding tube 320 and enters the buffer blanking channel 213 through the beverage can inlet and outlet 214; as can be seen, when the opening/closing driving cylinder 331 drives the shutter 332 to extend, the shutter 332 intercepts the beverage can 20 at the beverage can guiding tube 320 again, thereby preventing the beverage can 20 from discharging;
When the beverage can 20 enters the buffer blanking channel 213, the beverage can 20 slides along the buffer blanking channel 213 under the action of gravity and stays at the bottom of the buffer blanking channel 213;
Next, the drum driving part 220 drives the buffer blanking drum 210 to rotate again, and in the process of the rotation of the buffer blanking drum 210, the buffer blanking drum 210 does not rotate, but stays at the bottom of the buffer blanking channel 213; the drum driving part 220 drives the buffer blanking drum 210 to rotate, so that the beverage can inlet and outlet 214 on the outer rotary ring 212 reaches the bottom of the buffer blanking channel 213, and at this time, the beverage can 20 falls down through the beverage can inlet and outlet 214 under the action of gravity because the beverage can 20 also stays at the bottom of the buffer blanking channel 213.
Next, the structural design principle of the above-described vending machine 10 having a plurality of independent storage bins will be described:
1. by arranging a plurality of beverage can storage bins 300, different types of beverages can be placed in different beverage can storage bins 300, so that the aim of commodity sales diversification is fulfilled;
2. The plurality of beverage can storage bins 300 are sequentially distributed along the edge of the buffer blanking drum 210 and are positioned at the upper half area of the buffer blanking drum 210, and the beverage cans 20 in the beverage can accommodating cavity 310 can more easily come out from the beverage can discharging holes 311 and reach the beverage can guiding pipes 320 under the action of gravity through the structural design;
3. The buffer blanking drum 210 is provided with an inner rotary ring 211 and an outer rotary ring 212, and a buffer blanking channel 213 in a ring shape is formed between the inner rotary ring 211 and the outer rotary ring 212, so that the beverage can 20 slides to the bottom along the buffer blanking channel 213 under the action of gravity, thereby realizing the purpose of buffer blanking;
4. In particular, the outer rotary ring 212 is provided with a beverage can inlet and outlet 214, and the beverage can inlet and outlet 214 either reaches the beverage can guide pipe 320 of each beverage can storage bin 300 to feed the beverage cans 20 or reaches the bottom of the buffer blanking channel 213 to discharge the beverage cans 20 along with the rotation of the buffer blanking drum 210, and it is known that the beverage can inlet and outlet 214 not only realizes the feeding function of the beverage cans 20, but also realizes the discharging function of the beverage cans 20.
As can be seen from the above description, the beverage cans 20 are stacked in the beverage can accommodating cavity 310 in a lying state, and friction is generated between adjacent beverage cans 20, which is detrimental to the smooth discharge of the beverage cans 20 from the beverage can discharge port 311, and thus the beverage cans 20 are clamped at the beverage can discharge port 311. In order to better solve the technical problem, especially, a beverage can stirring structure 340 (as shown in fig. 8) is disposed in the beverage can accommodating cavity 310, and the beverage can stirring structure 340 can perform reciprocating rotation, so as to stir the beverage can 20 in the beverage can accommodating cavity 310, and thus, the beverage can 20 can smoothly come out from the beverage can discharge hole 311, and the occurrence of the jamming phenomenon is prevented.
Further, as shown in fig. 8, the beverage can stirring structure 340 includes a stirring shaft 341 and four beverage can stirring rods 342 disposed on the stirring shaft 341, where the four beverage can stirring rods 342 are distributed in an annular array with the rotation shaft of the stirring shaft 341 as the center, and the rotation shaft of the stirring shaft 341 and the central axis of the beverage can storage bin 300 are on the same straight line. Thus, the four beverage can pulling rods 342 divide the beverage can accommodating cavity 310 into four areas, and the four areas are independent of each other, so that the extrusion force of the beverage cans 20 in the beverage can accommodating cavity 310 due to stacking is reduced as much as possible, the friction force between the beverage cans 20 is further reduced, the beverage can pulling structure 340 can rotate more freely, and after all the beverage cans 20 in one area are transferred, the beverage cans 20 in the other area can be transferred. It can be seen that the four beverage can levers 342 can simultaneously achieve the following two functions: on the one hand, the related driving mechanism drives the stirring rotating shaft 341 to rotate, and the stirring rotating shaft 341 drives the four beverage can stirring rods 342 to stir the beverage cans 20, so that the beverage cans 20 can smoothly come out of the beverage can discharge holes 311; on the other hand, the four beverage can levers 342 can divide the beverage can accommodating cavity 310 into four independent areas, so as to further reduce the huge friction force generated by stacking the beverage cans 20, and thus the beverage cans 20 can be easily pushed, so that the beverage cans 20 can smoothly come out from the beverage can discharging ports 311.
According to the unmanned vending machine with the plurality of independent storage bins, on one hand, the plurality of independent storage bins are arranged to achieve the purpose of commodity sales diversification, and on the other hand, commodities selected by consumers are conveyed to the material taking opening in a gentler mode to achieve the purpose of protecting the commodities.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
