Description

Technical Field

[0001] This utility model relates to the field of unmanned vending machine technology, and in particular to an unmanned automatic vending machine. Background Technology

[0002] Unmanned vending machines are automated retail devices that can automatically sell goods and provide services without human intervention, reducing labor costs. They are suitable for 24-hour operation scenarios and reduce overall costs such as site rental.

[0003] Currently, existing unmanned vending machines (such as patent publication number: CN211718963U) disclose an intelligent unmanned vending machine. When the staff needs to make a purchase, the shopper can step on a foot pedal button, which then activates a servo motor to drive the main shaft at one end to rotate. This causes the main shaft to retract the light-blocking cloth on the surface, exposing the vending machine for the shopper to choose from. At the same time, slogans are printed on the surface of the light-blocking cloth, and advertising boards are installed on the side of the vending machine. By setting up slogans and advertising boards, the machine aims to attract attention.

[0004] In the aforementioned patent, the shelf partitions of the vending machine are fixed. The fixed partition spacing cannot be flexibly adjusted, making it difficult to accommodate the display of various different sizes of goods at the same time, thus limiting the types of goods that can be sold. When dispensing goods, irregularly shaped goods are prone to rubbing against the partitions, causing blockages. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an unmanned automatic vending machine that solves the technical problems of fixed partition spacing not being able to be flexibly adjusted, making it difficult to simultaneously accommodate the display of various different sizes of goods, limiting the types of goods sold, and causing irregularly shaped goods to rub against the partitions during dispensing, leading to product blockage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An unmanned vending machine includes multiple housings and shelf panels, with at least two conveying units fixedly installed on the top of the shelf panels, each conveying unit having a conveyor belt inside, and also includes;

[0008] Multiple partition components are provided, each of which is disposed at the top of a shelf panel. Each partition component includes a hinge plate and a partition body. The end of each hinge plate is rotatably connected to the shelf panel. A self-rotating belt is rotatably installed inside each partition body.

[0009] Preferably, at least two support plates are fixedly installed on the top of the shelf panel, and two telescopic rods are fixedly installed on the top of each support plate;

[0010] Each of the support plates is fixedly mounted with a docking seat at its top, and each docking seat has multiple buffer grooves inside.

[0011] Preferably, the top of each of the two docking seats is fixedly installed with the same adjustment frame, the bottom of each adjustment frame is fixedly installed with a positioning plate, and the end of each positioning plate is provided with an arc-shaped protrusion.

[0012] Each of the adjustment frames is provided with two diagonal bracing plates inside, and the end of each diagonal bracing plate is rotatably connected to a hinge plate. The two diagonal bracing plates are installed alternately inside the adjustment frame, and two guide rods are fixedly installed on the side end of each adjustment frame.

[0013] Each of the spin belts is provided with multiple support rollers inside, and each support roller can rotate freely inside the partition body.

[0014] Compared with the prior art, the present invention has the following beneficial effects;

[0015] In this invention, the inclined support plate tilts and exerts a thrust on the partition body. Since the partition body and the top of the hinge plate can rotate relative to each other, and the adjusting frame provides support and guidance for the partition body, the partition body can only move horizontally. At the same time, as the adjusting frame descends, the hinge plate deflects to one side around the top, causing the partition body to descend and move, thus widening the distance between the partition bodies and ensuring that goods can pass through smoothly, thereby improving the vending machine's adaptability to different specifications of goods.

[0016] In this invention, the internal rotating belt and its supporting rollers of the partition body reduce the frictional resistance between the goods and the partition body. When the goods are moved by the conveying unit and come into contact with the side of the partition body, the rotating belt can rotate freely, preventing the goods from stopping due to excessive friction, effectively avoiding blockages and ensuring smooth goods transport.

[0023] This application provides an unmanned vending machine that effectively solves the problem of fixed partition spacing being inflexible, making it difficult to simultaneously accommodate the display of various product sizes, thus limiting the types of goods sold. Furthermore, when dispensing goods, irregularly shaped items can easily rub against the partitions, causing blockages. The inclined support plate tilts, generating a pushing force on the partition body. Since the partition body and the top of the hinge plate can rotate relative to each other, and the adjusting frame provides support and guidance for the partition body, the partition body can only move horizontally. Simultaneously, as the adjusting frame descends, the hinge plate deflects to one side around its top, causing the partition body to descend and move, widening the spacing between the partition bodies and ensuring smooth passage of goods. This improves the vending machine's adaptability to different product sizes.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems of fixed partition spacing not being able to be flexibly adjusted, making it difficult to simultaneously accommodate the display of multiple different sizes of goods, limiting the types of goods sold, and causing irregularly shaped goods to rub against the partitions during shipment, leading to blockages. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides an unmanned automatic vending machine, including multiple housings 11 and shelf panels 12. At least two conveying units 13 are fixedly installed on the top of the shelf panels 12. Each conveying unit 13 is equipped with a conveyor belt inside. By stacking goods on the top of the conveying unit 13 in sequence, the goods are output and moved to one side by the rotating conveyor belt.

[0027] Multiple partition components are provided, each of which is located at the top of the shelf panel 12. Each partition component includes a hinge plate 14 and a partition body 15. The end of each hinge plate 14 is rotatably connected to the shelf panel 12. A self-rotating belt 16 is rotatably installed inside each partition body 15. The hinge plate 14 and the partition body 15 form a multi-segment bending design. The end of the hinge plate 14 is also rotatably connected to the shelf panel 12. The hinge plate 14 deflects to one side around the top, causing the partition body 15 to descend. At the same time, the partition body 15 moves with the swing direction of the hinge plate 14 to adjust the distance between the partition bodies 15. Meanwhile, the partition body 15 can rotate at the top of the hinge plate 14 to ensure that the partition body 15 is always in a vertical state.

[0028] At least two support plates 17 are fixedly installed on the top of the shelf panel 12. Two telescopic rods 19 are fixedly installed on the top of each support plate 17. By controlling the two telescopic rods 19, the telescopic rods 19 are compressed downward, and the top of the telescopic rods 19 exerts a downward pulling force on the adjusting frame 21, causing the adjusting frame 21 to move downward.

[0029] Each support plate 17 has a docking seat 18 fixedly installed at its top. Each docking seat 18 has multiple buffer grooves inside. The adjusting frame 21 moves downward, allowing the adjusting frame 21 to drive the positioning plate 23 to slide inside the docking seat 18.

[0030] The same adjustment frame 21 is fixedly installed at the top of each of the two docking seats 18. A positioning plate 23 is fixedly installed at the bottom of each adjustment frame 21. An arc-shaped protrusion is provided at the end of each positioning plate 23. The end of the positioning plate 23 rubs against the inner wall of the docking seat 18. The arc-shaped protrusion rubs against the inside of the docking seat 18 continuously. The arc-shaped protrusion is elastic. During the friction and sliding process, it continuously re-engages into the positioning groove. The positioning plate 23 plays a limiting role in the movement of the adjustment frame 21.

[0031] Each adjusting frame 21 has two inclined bracing plates 22 inside. The end of each inclined bracing plate 22 is rotatably connected to the hinge plate 14. The two inclined bracing plates 22 are staggered inside the adjusting frame 21. Two guide rods 24 are fixedly installed on the side end of each adjusting frame 21. When the adjusting frame 21 moves downward, the top of the guide rod 24 is connected to the partition body 15, and the end of the inclined bracing plate 22 is connected to the lower half of the partition body 15. Through the inclined bracing plate 22 moving at an angle, a thrust is generated on the partition body 15. First, the top of the partition body 15 and the hinge plate 14 rotate relative to each other. Since the adjusting frame 21 plays a supporting and guiding role for the partition body 15, the partition body 15 can only move horizontally. In addition, the adjusting frame 21 drives the partition body 15 to descend and expand the gap.

[0032] Each spinning belt 16 has multiple support rollers inside, and each support roller can rotate freely inside the partition body 15. The spinning belt 16 is located on one side of the partition body 15. The conveying unit 13 carries the goods and rubs against the side end of the partition body 15. Since the spinning belt 16 rotates freely, the frictional resistance between the goods and the partition body 15 is reduced, preventing blockage.

[0033] Working principle:

[0034] The first step is to stack the goods on top of the conveying unit 13 in sequence. At this time, the hinge plate 14 and the partition body 15 of the partition assembly are in the initial position, and a certain distance is maintained between the partition bodies 15 to separate different types of goods. The conveyor belt inside the conveying unit 13 and the spinning belt 16 inside the partition body 15 are both in a stationary state. When a certain product needs to be output, the conveyor belt inside the conveying unit 13 starts to rotate, and the conveyor belt drives the goods stacked on top of it to move to one side.

[0035] Two telescopic rods 19 at the top of the control support plate 17 are compressed downwards, generating a downward pulling force on the adjusting frame 21. The adjusting frame 21 begins to move downwards. As the adjusting frame 21 moves downwards, it drives the positioning plate 23 to slide inside the docking seat 18. The arc-shaped protrusion at the end of the positioning plate 23 rubs against the inner wall of the docking seat 18 and continuously re-engages into the positioning groove during the sliding process, thus limiting the movement of the adjusting frame 21 and ensuring its stable movement. Two staggered bracing plates 22 are installed inside the adjusting frame 21, with their ends rotatably connected to the hinge plate 14. When the adjusting frame 21 moves downwards, the bracing plates 22 tilt, generating a pushing force on the partition body 15. Since the partition body 15 and the top of the hinge plate 14 can rotate relative to each other, and the adjusting frame 21 provides support and guidance for the partition body 15, the partition body 15 can only move horizontally. At the same time, as the adjusting frame 21 descends, the hinge plate 14 deflects to one side around its top, causing the partition body 15 to descend and move, increasing the distance between the partition bodies 15 so that goods can pass through smoothly.

[0036] In the second step, as the goods are moved by the conveyor unit 13, they will come into contact with the side of the partition body 15. Since the spin belt 16 inside the partition body 15 is equipped with multiple freely rotatable support rollers, the spin belt 16 can rotate freely, reducing the frictional resistance between the goods and the partition body 15, and preventing the goods from getting stuck due to excessive friction during movement. As the conveyor belt of the conveyor unit 13 continues to rotate and the spacing of the partition components is adjusted and the frictional resistance to the goods is reduced, the goods are smoothly conveyed to the dispensing port of the vending machine for customers to take away.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
