Description

Technical Field

[0001] The present invention relates to the field of unmanned vending cabinets, and in particular to an unmanned vending cabinet for an unmanned supermarket. Background Art

[0002] With the continuous development of science and technology and the accelerated pace of people's lives, unmanned supermarkets have gradually emerged as a new retail model. As an important part of unmanned supermarkets, unmanned vending machines can realize self-service selection and payment of goods, providing consumers with a more convenient and efficient shopping experience.

[0003] The existing unmanned bottled beverage vending machines mostly ship the bottled beverage by pushing it from the bottom of the front, and the bottled beverage randomly falls into the cargo trough below. The user can manually push open the baffle and take out the bottled beverage. First of all, for bubble-type bottled beverages, the bottled beverage will be pushed from the bottom of the front to make it randomly fall into the cargo trough. The bottled beverage will cause gas expansion due to the violent impact. When the user opens the beverage later, the beverage is easy to spray quickly, which will bring a bad user experience and may even cause waste or dirty the user's clothes. For example, common carbonated beverages, after being subjected to a large impact, the solubility of the internal carbon dioxide gas decreases, the gas expands rapidly, and the beverage will spray out quickly when the bottle cap is opened.

[0004] Secondly, the existing unmanned bottled beverage vending machines ship in a way that when bottled beverages fall into the cargo trough, they will generate a large impact force. For fragile packaging products such as glass bottled beverages, they are easily broken and damaged during the falling process. If multiple glass bottled beverages are purchased at one time, the multiple glass bottled beverages will collide with each other during the falling process and cause them to break. Therefore, this type of vending machine cannot sell such products. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1-9 As shown, the present invention provides a technical solution:

[0038] An unmanned vending cabinet for an unmanned supermarket comprises a cabinet body 1, a top plate 2 is arranged at the top of the cabinet body 1, a plurality of pickup ports 3 are arranged side by side between the top plate 2 and the cabinet body 1, a dustproof mechanism is arranged between the pickup port 3 and the top plate 2, the dustproof mechanism comprises a telescopic slot 8, the telescopic slots 8 are arranged on both sides of the top plate 2 close to the pickup port 3, a plurality of springs 3 9 are arranged side by side inside the telescopic slot 8, a shielding plate 10 is fixedly connected to the other end of the spring 3 9, and the bottom end of the shielding plate 10 is inclined toward one side of the telescopic slot 8;

[0039] In this embodiment, the dustproof mechanism is reasonably coordinated with the spring three 9 and the baffle plate 10. When the pickup port 3 is not in use, the baffle plate 10 can tightly cover the pickup port 3 to form an effective physical barrier, effectively preventing external debris from entering the pickup port 3.

[0040] like Figure 3 , Figure 4 and Fig. 9 As shown, the same number of storage boxes 4 as the number of the pickup ports 3 are arranged side by side inside the cabinet 1, and a lifting mechanism is arranged below the storage boxes 4. The lifting mechanism includes a transmission shell 11, and the transmission shell 11 is fixedly installed at the bottom end of the storage boxes 4. Sprocket wheels 12 and sprocket wheels 2 13 are respectively arranged at both ends of the transmission shell 11. The sprocket wheels 12 and sprocket wheels 2 13 are movably connected through a chain 14. A motor 15 is arranged at the lower left side of the transmission shell 11, and the output shaft of the motor 15 is fixedly connected to the sprocket wheel 12. A screw rod 16 is movably provided, and the sprocket wheel 12 and the sprocket wheel 2 13 are fixedly connected to the screw rod 16. The lifting mechanism also includes a guide groove 17. The guide grooves 17 are penetrated and opened on both sides of the storage box 4. A lifting plate 18 is movably provided between the guide grooves 17. A lifting frame 19 is vertically provided at the top of the middle part of the lifting plate 18. Both ends of the lifting plate 18 are threadedly connected to the screw rod 16. A two-dimensional code identifier 7 is provided at the front corner of the cabinet 1, and a PLC is provided between the electric push rod 31, the motor 15, the motor 28 and the two-dimensional code identifier 7;

[0041] In the present embodiment, bottled beverages are stacked up and down and shipped from the top. During the shipping process, the beverages are pushed out smoothly from the top without causing severe impacts as in the traditional method, thereby effectively avoiding the problem of gas expansion caused by impacts. For example, when carbonated beverages are shipped in this vending machine, since they are not subjected to severe impacts, the internal gas state remains stable, and the beverages will not spray quickly when the user opens the bottle, thereby greatly improving the user experience.

[0042] Furthermore, bottled beverages are shipped out from the top in sequence. During the whole process, the beverages move relatively smoothly without falling and hitting the cargo trough. Therefore, bottled beverages with fragile packaging can be sold safely, such as specialty drinks in glass bottles. These can be sold normally in the unmanned vending machine, which not only enriches the variety of goods, but also meets the needs of different consumers and broadens the market sales scope.

[0043] like Figure 5 As shown, a fixing plate 5 is symmetrically arranged on both sides of the top of the storage box 4 and above the interior of the cabinet 1, and an opening and closing mechanism and a locking mechanism are respectively arranged on both sides of the fixing plate 5, and the opening and closing mechanism includes a rack 27, and racks 27 are arranged at the upper and lower corners of the outer ends of the same side of the two fixing plates 5, and a motor 28 is arranged on the right side of the interior of the cargo picking port 3 and close to the outside of the fixing plate 5, and a gear 29 is arranged at the output shaft end of the motor 28 and between the two racks 27, and the gear 29 is meshed with the rack 27, and the locking mechanism includes a mounting seat 30, and a mounting seat 30 is arranged on the left side of the interior of the cargo picking port 3 and close to the outside of the fixing plate 5, and an electric push rod 31 is fixedly installed on the back of the mounting seat 30, and a positioning block 32 is arranged on the side of the right fixing plate 5 close to the mounting seat 30, and a rod groove matching the output shaft of the electric push rod 31 is arranged between the positioning block 32 and the left fixing plate 5;

[0044] In this embodiment, the locking mechanism can tightly lock the two fixing plates 5 in the non-picking state through the cooperation of the electric push rod 31 and the positioning block 32. In this way, outsiders cannot easily open the pickup port 3 of the vending cabinet, which effectively prevents the theft of goods. Even in an unsupervised environment, the goods can be reliably protected, ensuring the property safety of the merchants and improving the reliability of operations. Reliable anti-theft measures make the operation of unmanned vending cabinets more stable and secure. Merchants do not need to worry too much about the risk of goods being stolen, and can focus more on the management of goods and the formulation of sales strategies, which is conducive to the long-term stable development of unmanned vending business.

[0045] like Figure 8As shown, a clamping mechanism 1 is provided on both sides of the interior of the storage box 4, and the clamping mechanism 1 includes a clamping plate 20. The clamping plates 20 are movably installed on both sides of the interior of the storage box 4, and a giving groove 21 matching the lifting plate 18 is opened in the middle of the clamping plate 20. A plurality of movable grooves 22 are arranged on both sides of the storage box 4 from top to bottom, and a spring 23 movably connected to the clamping plate 20 is arranged at one end of the inner side of the movable groove 22. A side shell 6 is arranged on the outside of the other two ends of the storage box 4, and a clamping mechanism 2 is arranged inside the side shell 6. The clamping mechanism 2 includes a clamping plate 24, and the clamping plate 24 is movably arranged inside the side shell 6. A plurality of guide rods 25 are arranged on the back of the clamping plate 24 from top to bottom. The end of the guide rod 25 passes through the side shell 6 and a spring 26 is arranged between the guide rod 25 and the outside of the side shell 6. The tops of the clamping plates 20 and 24 are both provided with inclined surfaces.

[0046] In this embodiment, when a smaller-sized bottled beverage is placed, spring 1 26 and spring 23 will make clamp 1 20 and clamp 2 24 appropriately close to each other to firmly clamp the beverage. When a larger-sized bottled beverage is placed, clamp 1 20 and clamp 2 24 will open appropriately under the squeeze of the beverage to accommodate the larger bottle body, while still maintaining effective fixation of the beverage. It can adapt to the clamping of bottled beverages of different sizes, greatly improving the versatility of the unmanned vending machine.

[0047] Working principle: When picking up goods, the user displays the QR code with payment information or purchase instructions in front of the QR code recognizer 7. The built-in optical sensor of the QR code recognizer 7 captures the QR code image, processes the image through a decoding algorithm, extracts the payment amount and product number contained therein, and transmits these data to the PLC. After receiving the QR code data, the PLC will first verify the data, including checking whether the payment amount is sufficient and whether the product number is valid. If the data verification passes, the PLC will determine the location of the cargo channel to be shipped and the corresponding electric control instructions based on the product number. According to the product location and shipping logic, the PLC will generate corresponding control instructions, which are used to control the operation of the electric push rod 31, motor 1 15, and motor 2 28 to ensure that the goods are accurately pushed out of the cargo channel;

[0048] Specifically, when the user's information is confirmed to be valid, the electric push rod 31, motor 15, and motor 28 at the corresponding position are started, wherein the electric push rod 31 withdraws the output shaft from the rod groove between the positioning block 32 and the left fixed plate 5 after starting, so that the two fixed plates 5 are in an unlocked state and can be opened toward both sides; after the motor 28 is started, the gear 29 is driven to rotate, and after the gear 29 rotates, the rack 27 is driven to move horizontally toward the outside, and the two fixed plates 5 are opened when the rack 27 moves; after the motor 15 is started, the sprocket 12 is driven to rotate, and the sprocket 12 drives the sprocket 2 13 to rotate through the chain 14, and the sprocket 12 and the sprocket 2 13 drive the screw 16 to rotate synchronously, and after the screw 16 rotates, the lifting plate 18 is driven to lift the height of a bottled beverage, and when the lifting plate 18 is lifted, the bottled beverage located inside the storage box 4 is ejected through the lifting frame 19. 5 is opened, so the ejected bottled beverage rises along the pickup port 3 and is pushed up from the bottom of the connection between the two shielding plates 10. Since a spring three 9 is arranged between the shielding plate 10 and the telescopic slot 8, when the shielding plate 10 is pushed upward, due to its inclined angle of the lower end surface, the spring three 9 will be compressed and retracted into the telescopic slot 8 until half of the bottled beverage passes through. The bottled beverage is placed horizontally here and is a columnar structure. Therefore, the spring three 9 will rebound and control the shielding plate 10 to be pushed out, and the bottled beverage will continue to be lifted and supported on the upper end of the connection between the two shielding plates 10. At this time, the user can take the bottled beverage. When the beverage is shipped, the motor two 28 and the electric push rod 31 are reversed, and the motor two 28 drives the two fixed plates 5 to block the upper end of the storage box 4. The electric push rod 31 controls the two fixed plates 5 to lock, so that after picking up the goods, the fixed plates 5 can be prevented from being opened when subjected to external force.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
