Description

Technical Field

[0001] The present invention relates to the technical field of vending machines, and particularly to an intelligent vending machine. Background Art

[0002] In the modern commercial retail field, vending machines, as an efficient and convenient retail terminal, are becoming increasingly popular. Traditional vending machines face many challenges in the commodity delivery process and urgently need to be improved.

[0003] The delivery structure design of traditional vending machines is often not reasonable enough. When pushing commodities such as beverage bottles for delivery, a single position or a simple method is mostly used for pushing. For example, only pushing the beverage bottle from one side or the bottom. In this case, the beverage bottle is extremely easy to topple due to uneven force during the delivery process. Once the beverage bottle topples, it will get stuck in the delivery channel, resulting in delivery failure. This not only affects the shopping experience of customers, reduces the use efficiency of the vending machine, but also increases the maintenance cost of the merchant. And when the cabinet shakes or the machine runs unstably, the commodities may accidentally fall in advance, causing commodity losses or delivery errors. For this reason, we introduce an intelligent vending machine. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent vending machine to solve the problems raised in the above background art.

A guide shelf for placing beverage bottles is arranged in the middle of the upper end of the delivery channel. An outer spiral spring and an inner spiral spring are respectively arranged on the inner and outer sides of the guide shelf; A baffle assembly is further arranged at the front end of the guide shelf. The baffle assembly uses the baffle to block from the bottom of the frontmost beverage bottle; A servo motor fixed at the rear end of the shelf assembly uses a driving mechanism to simultaneously drive the outer spiral spring and the inner spiral spring to rotate, so that the outer spiral spring and the inner spiral spring respectively push the beverage bottle along the guide shelf from the upper and lower parts of the beverage bottle. At the same time, the driving mechanism also drives the baffle assembly to rotate, so that the baffle assembly no longer blocks the frontmost beverage bottle.

[0006] Preferably, two groups of pickup openings are symmetrically arranged on the front end surface of the bottom of the cabinet. The pickup openings are communicated with the bottoms of the corresponding receiving slots, and a partition column is further arranged at the top between the two groups of receiving slots.

[0007] Preferably, the shelf assembly includes a base, side plates fixed on both sides of the upper end of the base, and a mounting frame fixed at the rear part of the upper end of the base; The servo motor is fixed to the rear end of the mounting bracket; Partition plates are evenly distributed between two sets of side plates. The shipping channel is located on the side of the corresponding partition plate, and the bottom of the partition plate is fixed to the upper end of the base.

The front end of the upper rotating shaft passes through the upper part of the rear end plate and is fixed with a first belt pulley. The rear part of the bottom rotating shaft passes through the bottom turntable and is fixed with a second belt pulley. A first belt is connected between the first belt pulley and the second belt pulley.

[0010] Preferably, the rear end of the bottom rotating shaft extends into the shaft hole at the bottom of the rear end plate.

[0011] Preferably, the output end of the servo motor is connected with a motor belt pulley, and the motor belt pulley is connected to a third belt pulley fixed to the rear part of the upper rotating shaft through a second belt.

[0012] Preferably, the goods guiding seat is located inside the outer spiral spring, the inner spiral spring is located at the bottom of the goods guiding seat, and the bottom rotating shaft is centered inside the inner spiral spring; The rear end of the inner spiral spring is fixed to the front end of the bottom turntable, and the rear end of the outer spiral spring is fixed to the outside of the circular fixed disk; The top of the inner spiral spring extends out from the rectangular slot.

[0014] Preferably, a limit retaining seat is arranged at the upper end of the rear part of the goods guiding seat. The limit retaining seat is located in front of the first belt pulley, and the bottom turntable is located in front of the middle of the limit retaining seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: When the present invention is shipped, the outer spiral spring and the inner spiral spring contact the beverage bottle from the upper rear side and the lower rear side of the beverage bottle respectively (that is, the outer spiral spring and the inner spiral spring have two upper and lower contact points with the rear side of the beverage bottle), and push the beverage bottle from these two positions. This design enables the beverage bottle to maintain balance when being pushed forward, preventing the beverage bottle from getting stuck in the shipping channel after tipping over, greatly ensuring the smoothness of the beverage bottle shipping process, reducing shipping failures caused by the beverage bottle getting stuck, and improving the working efficiency and stability of the vending machine.

[0016] The baffle component at the front end of the guide shelf can accurately control the falling timing of the beverage bottle. In the initial state, the top of the baffle is vertically upward, blocking in front of the beverage bottle to prevent the beverage bottle from accidentally falling when the cabinet shakes. After the outer spiral spring and the inner spiral spring rotate one week, the beverage bottle is pushed out. Subsequently, the next beverage bottle moves forward to the frontmost position. After the baffle rotates one week, the top is vertical again, blocking the beverage bottle to prevent it from falling. This precise control mechanism optimizes the shipping process of the beverage bottle and ensures that each shipment can proceed orderly. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment: Please refer to Figure 1-16 , the present invention provides a technical solution: An intelligent vending machine, including a cabinet body 1, and the internal refrigeration of the cabinet body 1 can reach the cold fresh standard of 2 - 6 °C.

[0021] Shelf assemblies 8 are arranged at equal intervals up and down inside the cabinet body 1, and two groups of goods receiving grooves 11 are symmetrically arranged at the bottom of the cabinet body 1; Two groups of pick-up openings 6 are symmetrically arranged on the front surface at the bottom of the cabinet body 1, the pick-up openings 6 communicate with the bottoms of the corresponding goods receiving grooves 11, and a partition column 7 is further arranged at the top between the two groups of goods receiving grooves 11 to prevent the goods falling from different delivery channels from interfering with each other.

[0022] On the upper parts of both sides of the front of the cabinet body 1, there are also chutes 3 for slidingly connecting the display screen 2. Inside the chutes 3, there are also electric telescopic rods for driving the display screen 2 to move up and down. The electric telescopic rods are controlled by the PLC built into the display screen 2. The piston rod at the output end of the electric telescopic rod is connected to the display screen 2. By extending or retracting the piston rod, the display screen 2 can be raised or lowered in the chute 3, so as to realize the adjustable height of the display screen 2 for the use of on-site customers. The display screen 2 can be used to display information such as pictures, names, and prices of the goods on sale. Through high-definition and vivid display, it can attract the attention of customers and stimulate the desire to purchase. When customers buy goods, the display screen 2 provides clear operation steps and prompt information to guide customers to complete processes such as shopping and payment, facilitating customers to use the vending machine. Customers can query detailed information of the goods through the display screen 2, such as ingredients, shelf life, usage methods, etc., and can also query relevant information such as the location, business hours, and customer service phone number of the vending machine. The display screen 2 integrates a payment interface and supports multiple payment methods, such as cash, bank card, QR code payment, face recognition payment, etc., enabling customers to complete the payment operation conveniently.

[0023] The display screen 2 also has a face recognition function. When customers start the payment, they only need to face the camera of the display screen 2. The system quickly and accurately identifies the customer's identity through face recognition technology and associates it with the pre-bound payment account, then the payment can be completed. The whole process does not require payment tools such as cash, bank card or mobile phone, greatly shortening the payment time and improving the convenience and fluency of shopping.

[0024] The shelf components 8 in the cabinet body 1 are distributed in two columns on the left and right. The corresponding display screen 2 can control the beverage bottles 12 on the corresponding shelf components 8 to fall into the corresponding receiving slots 11. After pushing the beverage bottle 12 forward, the beverage bottle 12 enters the corresponding pick-up port 6 through the corresponding receiving slot 11, and then the beverage bottle 12 can be taken away from the pick-up port 6. The beverage bottle 12 is a milk beverage or other beverage, and can be purchased and picked up independently.

[0025] On both sides of the front of the cabinet body 1, there are also card-swipe chips 4 located below the chutes 3. When the user brings a bank card or other payment card with a chip close to the card-swipe chip 4, the card-swipe chip 4 can quickly read the information in the card, including the card number, cardholder's name, expiration date, balance in the card, etc., so as to determine the user's payment account and realize card-swipe payment.

[0026] On both sides of the front of the cabinet body 1, there are also straw boxes 5 located below the card-swipe chips 4. The straw boxes 5 are used to place straws, and customers can take the straws by themselves after buying beverages.

[0027] On one side of the top of the cabinet body 1, there is an external camera 10; Customer behavior analysis: It is possible to observe the behavior of customers in front of the vending machine, such as the staying time of customers, the order of browsing products, whether there are companions, etc. By analyzing this data, merchants can understand the shopping habits and preferences of customers, providing a basis for optimizing product layout and adjusting marketing strategies. For example, if it is found that most customers will browse other related products before purchasing a certain type of product, the merchant can consider placing these products in a more prominent or convenient position to promote associated sales.

[0028] Surrounding environment monitoring: Monitor the environmental conditions around the vending machine, such as whether there are people gathering and whether there are potential safety hazards. When abnormal situations occur in the surrounding environment, such as someone lingering nearby for a long time, quarrels or fights breaking out, it can promptly alert the staff to ensure the safe operation of the vending machine and the personal safety of customers.

[0029] An in-built camera 9 is provided at the top of the inner side of the cabinet body 1; It can monitor the placement and remaining quantity of products inside the vending machine in real time. Through image recognition technology, the system can automatically count the quantity of products. When the quantity of a certain product is lower than the set value, it can promptly remind the staff to replenish the stock to ensure that the vending machine always maintains an adequate supply of products. It can also detect the display status of products, such as whether the products are neatly placed, whether there are any dropped or damaged situations, etc., so that the staff can promptly tidy up and maintain them.

[0030] Transaction monitoring: It can clearly record the whole process of customers purchasing products, including the process of customers selecting products, the payment process, and the product pickup actions, etc. This helps to provide accurate video evidence in case of transaction disputes, clarify responsibilities, and safeguard the legitimate rights and interests of merchants and customers. For example, when a customer claims to have paid successfully but fails to pick up the product, or when a merchant finds that the product inventory does not match the sales record, the cause can be found by viewing the video recorded by the in-built camera.

[0031] Loss prevention and anti-theft monitoring: Prevent customers from obtaining products through improper means, such as behaviors like damaging the vending machine and forcibly taking products. Once abnormal behaviors are detected, the system can automatically trigger an alarm and send relevant information to the staff to promptly stop illegal acts and reduce the losses of merchants.

[0032] Shipping channels are equally spaced on the shelf assembly 8. The shelf assembly 8 includes a base 81, side plates 82 fixed to both sides of the upper end of the base 81, and a mounting bracket 84 fixed to the rear of the upper end of the base 81; The servo motor 83 is fixed to the rear end of the mounting bracket 84; the servo motor 83 is controlled by a PLC.

[0033] There are partition plates 88 evenly distributed between two groups of side plates 82. The partition plates 88 form a shipping channel, and the shipping channel is located on the side of the corresponding partition plate 88. The bottom of the partition plate 88 is fixed to the upper end of the base 81.

[0034] In the middle of the upper end of the shipping channel, there is a guide shelf 86 for placing beverage bottles 12. The guide shelf 86 includes a guide seat 863 located in the middle of the shipping channel, a rear end plate 862 fixed to the rear end of the guide seat 863, a ramp plate 867 fixed to the middle of the front end of the guide seat 863, and support plates 866 arranged on both sides of the front part of the guide seat 863. The ramp plate 867 on the guide seat 863 helps the beverage bottle 12 slide out smoothly.

[0035] The bottom of the rear end plate 862 and the support plates 866 are fixed to the upper end of the base 81, so that the guide seat 863 can be lifted, making the guide seat 863 at a certain distance from the upper end of the base 81, so that the outer spiral spring 87 is located outside the guide shelf 86.

[0036] An outer spiral spring 87 and an inner spiral spring 89 are respectively arranged on the inner and outer sides of the guide shelf 86. The guide seat 863 is located inside the outer spiral spring 87, and the rear end of the outer spiral spring 87 is fixed to the outside of the circular fixing plate 85. In this way, the servo motor 83 can drive the outer spiral spring 87 to rotate through the circular fixing plate 85, so that the top of the outer spiral spring 87 contacts the upper rear side of the beverage bottle 12, and under the continuous rotation of the outer spiral spring 87, the outer spiral spring 87 pushes the beverage bottle 12 forward from the upper part of the beverage bottle 12. The inner spiral spring 89 is located inside the bottom of the guide seat 863, and a rectangular slot 865 is provided in the middle of the guide seat 863, and the top of the inner spiral spring 89 extends out from the rectangular slot 865. In this way, when the inner spiral spring 89 rotates, the top of the inner spiral spring 89 can contact the bottom rear side of the beverage bottle 12, and under the continuous rotation of the inner spiral spring 89, the inner spiral spring 89 pushes the beverage bottle 12 forward from the bottom of the beverage bottle 12. In this way, under the simultaneous rotation of the outer spiral spring 87 and the inner spiral spring 89, the outer spiral spring 87 and the inner spiral spring 89 respectively contact the beverage bottle 12 from the upper rear side and the lower rear side of the beverage bottle 12 (that is, the outer spiral spring 87 and the inner spiral spring 89 have two contact points with the rear side of the beverage bottle 12 up and down), and push the beverage bottle 12 from the upper rear side and the lower rear side of the beverage bottle 12. In this way, when pushing the beverage bottle 12 forward, it can prevent the beverage bottle 12 from tipping over and getting stuck. This structural design ensures that the outer spiral spring 87 and the inner spiral spring 89 can accurately push the beverage bottle 12.

[0037] The bottom rotating shaft 13 is centered inside the inner spiral spring 89. The rear end of the inner spiral spring 89 is fixed to the front end of the bottom turntable 131. The bottom rotating shaft 13, the inner spiral spring 89, and the bottom turntable 131 form a whole and rotate synchronously.

[0038] The driving mechanism includes a circular fixed disk 85 driven by a servo motor 83, a bottom turntable 131 driven by the circular fixed disk 85, and a bottom rotating shaft 13 extending through the bottom turntable 131; The circular fixed disk 85 is located behind the goods guiding seat 863; A upper rotating shaft 833 is fixed in the middle of the circular fixed disk 85. The front end of the upper rotating shaft 833 is fixed with a first pulley 834 after passing through the upper part of the rear end plate 862. The rear part of the bottom rotating shaft 13 passes through the bottom turntable 131 and is fixed with a second pulley 864. A first belt 835 is connected between the first pulley 834 and the second pulley 864; The rear end of the bottom rotating shaft 13 extends into the shaft hole at the bottom of the rear end plate 862. A bearing is arranged in the shaft hole, and the bearing is sleeved on the outer side of the rear end of the bottom rotating shaft 13. Through the arrangement of the bearing, the rotation of the bottom rotating shaft 13 is smooth. And because the driving bevel gear 15 at the front end of the bottom rotating shaft 13 meshes with the driven bevel gear 17, the positions of the front and rear ends of the bottom rotating shaft 13 can be limited, ensuring the horizontal state of the front and rear of the bottom rotating shaft 13.

[0039] The output end of the servo motor 83 is connected with a motor pulley 831, and the motor pulley 831 is connected to a third pulley fixed to the rear part of the upper rotating shaft 833 through a second belt 832.

[0040] The PLC controls the operation of the servo motor 83. The motor pulley 831 drives the upper rotating shaft 833, the circular fixed disk 85 fixed on the upper rotating shaft 833, and the outer spiral spring 87 fixed to the front end of the circular fixed disk 85 to rotate through the second belt 832 and the third pulley fixed to the rear part of the upper rotating shaft 833; The upper rotating shaft 833 drives the bottom rotating shaft 13, the bottom turntable 131 on the bottom rotating shaft 13, and the inner spiral spring 89 fixed on the bottom turntable 131 to rotate through the first pulley 834, the first belt 835, and the second pulley 864; Since the first belt 835 is used for transmission between the upper rotating shaft 833 and the bottom rotating shaft 13, the rotation directions of the outer spiral spring 87 and the inner spiral spring 89 are the same; The pitches of the outer spiral spring 87 and the inner spiral spring 89 are the same. After the outer spiral spring 87 and the inner spiral spring 89 rotate synchronously for one circle, they can respectively push the beverage bottle 12 forward by a stroke from the upper rear side and the lower rear side of the beverage bottle 12, so that the frontmost beverage bottle 12 falls along the slope plate 867 into the receiving groove 11 and the corresponding picking opening 6.

[0041] A baffle assembly is also provided at the front end of the guiding shelf 86, and the baffle assembly blocks from the bottom of the frontmost beverage bottle 12. The baffle assembly includes a horizontal shaft 16 connected between two sets of support plates 866, a driven bevel gear 17 fixed on the horizontal shaft 16, baffles 14 fixed at both ends of the horizontal shaft 16 after passing through the support plates 866, and a driving bevel gear 15 fixed at the front end of the bottom rotating shaft 13; the driving bevel gear 15 meshes with the driven bevel gear 17, and the horizontal shaft 16 and the bottom rotating shaft 13 are arranged at a right angle.

[0042] This structural design enables the bottom rotating shaft 13 to drive the driven bevel gear 17 through the driving bevel gear 15 when rotating, and then enables the horizontal shaft 16 to rotate, realizing the rotation of the baffle 14 to block or release the beverage bottle 12.

[0043] The two sets of baffles 14 are located on the left and right sides in front of the frontmost beverage bottle 12. In the initial state, the top of the baffle 14 is vertically upward, so that the baffle 14 just blocks in front of the beverage bottle 12 to prevent the frontmost beverage bottle 12 from falling via the ramp plate 867 when the cabinet 1 shakes.

[0044] When the outer spiral spring 87 and the inner spiral spring 89 rotate simultaneously and push the beverage bottle 12 forward, the bottom rotating shaft 13 will drive the horizontal shaft 16 and the baffles 14 fixed at both ends of the horizontal shaft 16 to rotate through the driving bevel gear 15 and the driven bevel gear 17. The baffle 14 with the top in the vertical state rotates forward towards the front of the shipping channel, giving way to the forward movement of the frontmost beverage bottle 12, so that the frontmost beverage bottle 12 can move forward smoothly until the frontmost beverage bottle 12 falls into the receiving slot 11 and the corresponding picking opening 6 via the ramp plate 867. Subsequently, the next beverage bottle 12 moves forward to the frontmost position. At this time, after the baffle 14 rotates one week, the top of the baffle 14 is in the vertical state again, so that the baffle 14 can block the frontmost beverage bottle 12 from the bottom again to prevent it from falling.

[0045] The servo motor 83 fixed at the rear end of the shelf assembly 8 uses a driving mechanism to drive the outer spiral spring 87 and the inner spiral spring 89 to rotate simultaneously, so that the outer spiral spring 87 and the inner spiral spring 89 respectively push the beverage bottle 12 out along the guiding shelf 86 from the upper and lower parts of the beverage bottle 12. At the same time, the driving mechanism also drives the baffle assembly to rotate, so that the baffle assembly no longer blocks the frontmost beverage bottle 12.

[0046] The limit retaining seat 861 is provided at the upper rear end of the goods guiding seat 863. The limit retaining seat 861 is located in front of the first pulley 834. The limit retaining seat 861 is used to block the first pulley 834, the first belt 835 and the circular fixing plate 85, so as to prevent the beverage bottle 12 from contacting the first pulley 834, the first belt 835 and the circular fixing plate 85 when the first beverage bottle 12 is placed on the goods guiding seat 863.

[0047] The rear end of the rectangular slot 865 extends beyond the limit retaining seat 861, so that the first belt 835 can be located behind the limit retaining seat 861 and pass through the inner rear end of the rectangular slot 865. The bottom turntable 131 is located in front of the middle of the limit retaining seat 861. When the bottom turntable 131 drives the inner spiral spring 89 to rotate, the top of the rear end of the inner spiral spring 89 will not contact the bottom of the limit retaining seat 861, thus preventing the limit retaining seat 861 from hindering the rotation of the inner spiral spring 89.

[0048] Specifically, during use, when goods need to be shipped, the servo motor 83 fixed to the rear end of the shelf assembly 8 is started, and the outer spiral spring 87 and the inner spiral spring 89 are simultaneously driven to rotate through the drive mechanism. The output end of the servo motor 83 is connected with a motor pulley 831. The motor pulley 831 is connected to the third pulley fixed to the rear part of the upper rotating shaft 833 through the second belt 832, thereby driving the upper rotating shaft 833 to rotate. The front end of the upper rotating shaft 833 is fixed with a first pulley 834 after passing through the upper part of the rear end plate 862. At the same time, the rear part of the bottom rotating shaft 13 passes through the bottom turntable 131 and is fixed with a second pulley 864. A first belt 835 is connected between the first pulley 834 and the second pulley 864, so that the rotation of the upper rotating shaft 833 can drive the bottom rotating shaft 13 to rotate through belt transmission.

[0049] The rear end of the outer spiral spring 87 is fixed to the outside of the circular fixing plate 85, and the rear end of the inner spiral spring 89 is fixed to the front end of the bottom turntable 131. When the bottom rotating shaft 13 and the upper rotating shaft 833 rotate, they drive the bottom turntable 131 and the circular fixing plate 85 to rotate respectively, and further drive the outer spiral spring 87 and the inner spiral spring 89 to rotate.

[0050] The outer spiral spring 87 and the inner spiral spring 89 push the beverage bottle 12 out along the goods guiding shelf 86 from the upper part and the lower part of the beverage bottle 12 respectively. At the same time, the rotation of the bottom rotating shaft 13 drives the driving bevel gear 15 to rotate, and through the driven bevel gear 17, the baffle 14 rotates and no longer blocks the beverage bottle 12 at the forefront, ensuring that the beverage bottle 12 can be smoothly pushed out of the shipping channel.

[0051] The next beverage bottle 12 moves forward to the frontmost position. At this time, after the baffle 14 rotates one full circle, the top of the baffle 14 is again in the vertical state, so that the baffle 14 can block the frontmost beverage bottle 12 again from the bottom of the beverage bottle 12 to prevent it from falling.

[0052] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
