Description

Technical Field

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

[0002] The vending process of a vending machine is a complex collaborative process involving mechanical, electronic and software control. Modern vending machines have even joined the Internet platform for intelligent sales. Different types of intelligent vending machines (such as spring aisles, serpentine aisles, crawler aisles, etc.) have slight differences in specific operations, but the overall process is similar. Consumers click on the product display area on the Internet sales platform to view the available products. After selecting a product, they can tell the vending machine what they want to buy by touching the corresponding product icon on the screen.

[0003] Although some existing smart vending machines have integrated Internet technology to perform intelligent sales operations and can place orders independently of the after-sales machine itself, after receiving the order, the delivery structure of the vending machine must be designed for products of regular shapes and sizes, such as common bottled beverages, canned foods, etc.; for products with irregular shapes, too large or too small, the delivery process is prone to problems such as jamming and falling. With the integration of Internet platforms, the types of goods that can be sold by smart vending machines are becoming more and more diverse, not only limited to conventional beverages and snacks, but also extending to other products. For example, some uniquely shaped toys, special-shaped gifts, etc. are difficult to sell smoothly in the existing standard delivery structure. Moreover, each product must have a dedicated drive unit to perform the delivery operation. In order to achieve easy delivery of products, the structural design is more complicated.

[0004] For example, there are three main types of traditional delivery structures: one is the spring aisle vending machine. For vending machines with spring aisles, each aisle corresponds to a commodity. When the user selects a commodity, the motor drives the spring of the corresponding aisle to rotate, and the commodity placed on the spring is pushed out of the aisle. The commodity falls into the pickup port along the sliding track, and the goods are released by pushing. The other is the serpentine aisle vending machine: it is often used to sell bottled beverages and other commodities. The delivery channel is multi-layered and spiral, and the commodities are placed in the aisle; when delivering, the motor drives the push plate to move, and the commodity at the specified position is pushed out of the aisle and falls to the pickup port. The last type is the crawler aisle vending machine: that is, the commodity is placed on the crawler. When receiving the delivery instruction, the motor drives the crawler to operate and transport the user's selected commodity to the pickup port.

[0005] Among the above three traditional shipping structures, although the first structure is simple, it relies on pushing to release goods, which requires a large number of pushing components to be set. Moreover, if the pushing stroke is too large, it will make the overall vending machine more bloated. Because only large-sized goods have a larger pushing stroke, and large-sized goods themselves already occupy a relatively large space. Coupled with the pushing stroke when the goods are fully pushed out and dropped for release, it undoubtedly increases the design size of the vending machine. In addition, for the other two shipping structures, whether it is a spiral shipping channel or a track drive for conveying, they also have great limitations in terms of the size of the goods, and the structure is undoubtedly more complex. During the transmission process, it is more likely to have a jamming failure. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides an intelligent vending machine to solve the problems of poor shipment and poor versatility of intelligent vending machines in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solution: An intelligent vending machine includes a plurality of horizontally arranged goods storage bins located inside the cabinet, and an intelligent shopping module integrated on the Internet platform. After the intelligent shopping module obtains shopping information, it releases the corresponding goods through a shipping component. One side of the bottom plate of the goods storage bin is hingedly installed inside the cabinet through a fixed hinge column, so that the bottom plate is installed in a cantilevered manner. The hinge column is in plug-in fit with a pin that is slidably installed inside the cabinet to achieve clamping, so that the bottom plate can support and store goods; The shipping component includes a rotating rod that is horizontally installed inside the cabinet and can rotate and then move axially. A plurality of driving components are spirally arranged along the axial direction of the rotating rod, and all the driving components do not cross and overlap in the axial projection of the rotating rod. So that when the rotating rod rotates by an angle, only one driving component can drive its corresponding pin to disengage from the hinge column; The lower part of one side of the bottom plate is supported by an elastic support member, and the support member can only push the bottom plate to the horizontal position to close the bottom outlet of the goods storage bin when there is no goods stored on the bottom plate; The rotating rod has a plurality of set rotation angles, and each rotation angle corresponds to a kind of goods; When the intelligent shopping module receives an order for purchasing the corresponding goods, the rotating rod first rotates by a rotation angle corresponding to this kind of goods, and then the rotating rod moves axially by a set displacement, so that the driving component makes the pin disengage from the hinge column.

[0008] Furthermore, the rotating rod is rotatably installed in a crossbeam in the cabinet, and the driving assembly includes a plurality of top rods arranged in a spiral along the axial direction of the rotating rod, and the projections of all the top rods in the axial direction of the rotating rod do not cross or overlap with each other, and the interior of the crossbeam where each top rod is located has a corresponding annular groove, and the annular groove allows the top rod to rotate together with the rotating rod inside the annular groove; an intermediate hole is provided at the bottom of the annular groove, and all the intermediate holes are arranged in the same spiral arrangement in the axial direction of the rotating rod, and a sliding block is axially elastically slidably installed in the intermediate hole, and when the sliding block is not working, one end of the sliding block is exposed outside the intermediate hole and extends into the annular groove, so that every time the rotating rod rotates a set angle, only a single top rod is in compression contact with the end of the corresponding sliding block.

[0009] Furthermore, the sliding block includes a slider, a sliding column and a sliding rod. The slider is slidably installed in the annular groove. The sliding column is used to connect the slider and the sliding rod, and the sliding rod is provided with a cylindrical spring at both ends which are respectively connected to the bottom of the annular groove and the end surface of the slider. The sliding column is used to connect one end of the sliding rod and is located in the middle hole. After the sliding rod axially slides through the middle hole, the pin can be completely pushed out of the hinge column under the push of the push rod.

[0010] Furthermore, a longitudinal beam is fixed perpendicularly to the cross beam, and the longitudinal beam separates all cargo storage compartments. The hinged column is rotatably installed inside one side of the longitudinal beam, and one end located inside the longitudinal beam has a slot for the bayonet to be inserted.

[0011] Furthermore, a moving block installed in the longitudinal beam for horizontal sliding is connected by a return tension spring in the longitudinal beam, and in a non-working state, the moving block is in a position away from the hinge column; the bayonet pin is coaxially arranged outside the notch of the slot, and the bayonet pin is fixed as a whole through a horizontal connecting rod and a sliding column, the sliding column extends out of the mounting slot where it is located toward one end of the hinge column, and the other end is connected to a return cone spring connected to the bottom of the mounting slot, and in a non-working state, the return cone spring makes one end of the sliding column exposed from the mounting slot and the bayonet pin is inserted into the slot, and when the sliding rod pushes the moving block and approaches the hinge column, the sliding column is completely pushed back into the mounting slot, and the bayonet pin is completely disengaged from the slot.

[0012] Furthermore, the lower edge of one end of the moving block away from the hinge column has an inclined surface formed by chamfering, and the sliding rod contacts the inclined surface to horizontally move the moving block.

[0013] Furthermore, one end of the sliding rod in contact with the inclined surface is a hemispherical surface; a connecting block is fixed on the upper surface of the moving block, and the connecting block is connected to the reset tension spring.

[0014] Further, the elastic support member includes a load-bearing block fixed on the cross beam. An accommodation cavity for the rotation and installation of one side of the bin bottom plate is provided inside the load-bearing block. When one side edge surface of the cavity opening of the accommodation cavity contacts the bin bottom plate, the bin bottom plate is in a horizontal state. When the other side edge surface contacts the bin bottom plate, the bin bottom plate is in a vertical state.

[0015] Further, the elastic support member further includes a curved rod and a curved spring. The curved spring is bendably located inside the load-bearing block. The center of the bending direction of the curved rod falls on the axis of the hinge column. One end of the curved rod always keeps pressing contact with the bin bottom plate. The other end is slidably inserted into the load-bearing block and connected to the curved spring. The elastic force of the curved spring can only push the bin bottom plate to the horizontal state when there is no cargo on the bin bottom plate.

[0016] Further, the end of the slider in contact with the ejector rod is an end face with rounded corners on both sides. One end of the rotating rod is in transmission connection with the main shaft of a driving motor vertically and slidably installed on the side surface of the cabinet body. The main shaft is a telescopic rod.

[0017] The present invention provides an intelligent vending machine, which has the following beneficial effects: 1. The intelligent vending machine in the present invention has a simple structure and is easy to manufacture. Compared with the traditional spring cargo channel, it adopts a cantilever hinge-mounted bin bottom plate, and uses the downward swing action of the bin bottom plate for the shipping operation. Compared with pushing, it is easier to realize the dropping of goods, and the design size of the cabinet thickness is undoubtedly greatly reduced. At the same time, a rotating rod is specially used, and a series of ejector rods are arranged in a spiral manner, so that multiple cargo storage bins can be driven by the same driving element to realize shipping, and there is no need to design a dedicated driving unit for each cargo storage bin to perform the shipping operation.

[0018] 2. In the intelligent vending machine of the present invention, on the basis of the linear arrangement of multiple bin bottom plates, a very large vertical space is provided below the bin bottom plate as the shipping channel, and there is no need to design the shipping channel as the traditional snake-shaped cargo channel vending machine and the crawler-type cargo channel vending machine. The structure is simple and practical and easy to manufacture, so it has greater versatility and can facilitate the output of more types of commodities.

[0019] 3. Since orders can be placed directly on the Internet platform such as the mobile phone, there is no need to rely solely on the operation panel of the vending machine for ordering, which well avoids the embarrassing situation that the vending machine cannot place an order due to lack of maintenance or the operation panel being damaged when exposed outdoors. In addition, due to the stronger versatility of the present invention, it can adapt to the automatic and rapid shipping of more types of commodities, so it can greatly meet the requirements of the wide range of sales categories on the Internet platform.

Specific embodiments

[0022] This specification will clearly and completely express the technical solutions in the following embodiments based on the accompanying drawings of the embodiments of the present invention. The embodiments described in this specification are only some of the embodiments of the present invention, not all embodiments. All other embodiments inspired and extended by those skilled in the art based on these embodiments in this application without creative efforts should fall within the protection scope of the present invention.

[0023] A vending machine introduced in this embodiment, like the existing vending machines, mainly includes a number of horizontally arranged goods storage bins 2 located in the cabinet 1. There is a pickup opening at the bottom of the cabinet 1, usually this pickup opening is set at the bottom of the front side of the cabinet 1. This vending machine also has an intelligent shopping module integrated with the Internet platform. Consumers can place orders on the corresponding Internet shopping platform without operating the control panel on the cabinet 1, which can effectively avoid the problem that the panel of the cabinet 1 is prone to failure due to lack of maintenance or exposure to the outdoors. After the intelligent shopping module in the platform obtains the shopping information of consumers, it automatically releases the corresponding goods through a delivery component. Specifically, in this embodiment, as Figures 1-4As shown, on one side of the floor plate 3 of the goods storage bin 2, for example, the side facing the front, it is hingedly installed in the cabinet 1 through a fixed hinge post 12. The hinge post 12 can be fixed integrally with the floor plate 3 or integrally formed, so that the floor plate 3 is installed in a cantilevered manner. Specifically, the hinge post 12 is inserted and matched with a pin 13 slidably installed in the cabinet 1 to achieve snap connection, so as to achieve the purpose of cantilevered installation, enabling the floor plate 3 to support and store goods. Once the pin 13 disengages from the hinge post 12, the floor plate 3 will flip downward, and then release the goods, allowing the goods to roll out from the corresponding channel. As for the way the goods roll out or slide out of the cabinet 1, in this embodiment, a simplified design is carried out. Based on the above setting rule of the floor plate 3, a vertical space can be directly divided in the space of the cabinet 1 below the floor plate 3, that is, the vertical space is directly located below this floor plate 3. All the floor plates 3 share this large vertical space as the channel for transporting goods. This can prevent the goods from getting stuck in the shipping channel, expand the space for shipping goods, and perform unobstructed transportation in a vertically falling manner, which is more conducive to the goods directly falling to the bottom of the cabinet 1. Of course, the bottom surface in the cabinet 1 can be an arc surface, so that the goods can be as close as possible to the front side of the pick-up port after falling, facilitating picking up goods. During use, once the above-mentioned floor plate 3 flips downward and opens, the goods will fall into this huge and empty channel, and then roll or slide to the pick-up port at the bottom end of the cabinet 1.

[0024] As for the structural design logic of the pin 13 disengaging from the hinge post 12 to release the goods, continue to refer to Figures 1-4 , it can be that this shipping component includes a rotating rod 5 horizontally installed in the cabinet 1, which can rotate and then axially move. On the rotating rod 5, several driving components are arranged helically along its axis, and all the driving components do not cross and overlap in the axial projection of the rotating rod 5. The purpose is that when the rotating rod 5 rotates by an angle, only one driving component can drive its corresponding pin 13 to disengage from the hinge post 12 and release the goods. In addition, as Figure 6 , below one side of the floor plate 3 in this embodiment, it is supported by an elastic support member, and the elastic force of this support member is only sufficient to support the floor plate 3 to the horizontal position when there is no goods stored on the floor plate 3, so as to close the bottom outlet of the goods storage bin 2, avoiding that when the elastic force is too large, even if the pin 13 disengages, the floor plate 3 cannot swing downward to release the goods, resulting in shipping failures.

[0025] More specifically, in this embodiment, the rotating rod 5 has a number of set rotation angles, and each rotation angle corresponds to a cargo. For example, every time it rotates 30 degrees, another cargo will fall out from the corresponding bin bottom plate 3. During use, when the intelligent shopping module receives a purchase order for the corresponding cargo, the rotating rod 5 rotates a rotation angle according to the cargo type information in this order. When the rotating rod 5 rotates from the initial position to this angle, and then the rotating rod 5 axially moves a constant set displacement, the driving component can make the latch 13 disengage from the hinge post 12.

[0026] As one of the specific design structures, as Figures 1-2 , this rotating rod 5 is rotatably installed in the cross beam 4 inside the cabinet 1. The driving component includes a number of ejector rods 6 arranged at intervals along the axial direction of the rotating rod 5 in a spiral path. As Figure 6 shown, the projections of all the ejector rods 6 on the axial direction of the rotating rod 5 do not cross and overlap each other, and there is a circular groove 21 corresponding to the inside of the cross beam 4 where each ejector rod 6 is located. The circular groove 21 allows the ejector rod 6 to rotate with the rotating rod 5 inside it. There is a middle hole 22 at the bottom of the circular groove 21, and all the middle holes 22 are arranged in the same spiral arrangement form on the axial direction of the rotating rod 5. A sliding block is elastically slidably installed axially in the middle hole 22. In the non-working state, one end of the sliding block protrudes outside the middle hole 22 and thus extends into the circular groove 21. In this way, every time the rotating rod 5 rotates a set angle, only a unique ejector rod 6 squeezes and contacts the end of its corresponding sliding block, releasing the hinge post 12 of the bin bottom plate 3 corresponding to the cargo, so as to achieve the purpose of automatic goods delivery.

[0027] In this embodiment, as Figure 2 shown, this sliding block includes a slider 7, a sliding column 8 and a sliding rod 10. The slider 7 is slidably installed in the circular groove 21. This sliding column 8 is used to connect the slider 7 and the sliding rod 10, and a cylindrical spring 9 with both ends connected to the bottom of the circular groove 21 and the end face of the slider 7 is sleeved on the sliding rod 10 to realize the elastic telescopic installation of the slider 7. During specific production, one end of the sliding column 8 used to connect the sliding rod 10 can be located inside the middle hole 22. After the sliding rod 10 axially slides through the middle hole 22, under the pushing of the ejector rod 6, the latch 13 can be completely pushed out of the hinge post 12, releasing the hinge post 12 and causing the bin bottom plate 3 to swing downward.

[0028] As a specific implementation structure, as Figure 1 、 Figure 2, a longitudinal beam 11 is fixedly mounted perpendicular to the cross beam 4, and the longitudinal beam 11 separates all the cargo storage bins 2. A hinged column 12 is rotatably mounted inside one side of the longitudinal beam 11, and at the end of the hinged column 12 located inside the longitudinal beam 11, there is specifically a slot 20 for a locking pin 13 to be inserted. Inside the longitudinal beam 11, a moving block 17 horizontally slidably mounted inside the longitudinal beam 11 is also connected by a return spring 19. Moreover, in the non-operating state, this moving block 17 is in a position away from the hinged column 12. In addition, a locking pin 13 is coaxially provided outside the notch of the slot 20. This locking pin 13 is integrally fixed with a sliding column 14 through a horizontal connecting rod and moves together. In this embodiment, at the end of the sliding column 14 facing the hinged column 12, normally it extends out of its mounting groove 16 to wait for contact with the moving block 17; the other end of the sliding column 14 is connected to a return conical spring 15 connected to the bottom of the mounting groove 16. Moreover, in the non-operating state, when the return conical spring 15 makes one end of the sliding column 14 expose out of the mounting groove 16, it is necessary to ensure that the locking pin 13 is inserted into the slot 20, that is, normally, the bin bottom plate 3 is locked. When shipping goods, when the sliding rod 10 moves upward to push the moving block 17, and the moving block 17 approaches the hinged column 12, the sliding column 14 is completely pushed back into the mounting groove 16, and at the same time, the locking pin 13 is completely disengaged from the slot 20, and the bin bottom plate 3 automatically opens for shipping. In order to facilitate the movement of the sliding block 7, the lower edge of the end of this moving block 17 facing away from the hinged column 12 has an inclined surface formed by a chamfer, and the sliding rod 10 contacts the inclined surface to horizontally move the moving block 17.

[0029] As a specific manufacturing structure, such as Figure 2 , the end of this sliding rod 10 in contact with the inclined surface is a hemispherical surface. A connecting block 18 is fixed on the upper surface of the moving block 17, and the connecting block 18 is connected to the return spring 19 to achieve elastic sliding connection.

[0030] As a specific design structure, such as Figure 5 , this elastic support member includes a bearing block 23 fixed on the cross beam 4, which can be specifically installed at the center of one side of each bin bottom plate 3. The bearing block 23 has an accommodation cavity for the one side of the bin bottom plate 3 to be rotatably mounted inside. During manufacturing, when one side edge surface of the cavity opening of this accommodation cavity contacts the bin bottom plate 3, the bin bottom plate 3 is in a horizontal state, that is, the storage state, and when the other side edge surface contacts the bin bottom plate 3, the bin bottom plate 3 is in a vertical state, that is, the shipping state. After the goods fall, the bin bottom plate 3 automatically flips up and resets under the action of the support member, waiting for the goods in the cabinet 1 to be automatically replenished.

[0031] Specifically in practice, such as Figure 5The elastic support also includes a curved rod 24 and a curved spring 25. The curved spring 25 can be bent and located in the bearing block 23. The center of the curved rod 24 in the bending direction falls on the axis of the hinge column 12, so that the warehouse bottom plate 3 can rotate. One end of the curved rod 24 is always in extrusion contact with the warehouse bottom plate 3, and the other end is inserted into the bearing block 23 in a sliding manner and connected to the curved spring 25 to receive the elastic thrust from the curved spring 25. Moreover, the elastic force of the curved spring 25 can only push the warehouse bottom plate 3 to a horizontal state when there is no cargo on the warehouse bottom plate 3, that is, after the cargo automatically falls, the warehouse bottom plate 3 can be automatically reset and wait for the cargo conveying mechanism in the cabinet 1 to automatically add cargo.

[0032] In the above embodiment, in order to facilitate the smooth axial movement of the rotating rod 5 to the set displacement after the rotating rod 5 is rotated to the right position, so as to squeeze the slider 7, it is best to process the end of the slider 7 that contacts the push rod 6 as follows: Figure 2 The rounded end faces on both sides shown in the figure, the arc surface 701 formed by the rounded corners is conducive to the movement and transition of the top rod 6 during extrusion. As for the axial movement and rotation of the rotating rod 5, as shown in the figure, Figure 1 As shown, one end of the rotating rod 5 may be connected to the main shaft of the driving motor 26 vertically slidably mounted on the side of the cabinet. Figure 6 As shown, a connecting hole is processed at the end of the rotating rod 5, and a transmission structure such as a keyway is set on the hole wall to realize rotation of a corresponding angle. Moreover, the main shaft is a telescopic rod, which can push the rotating rod 5 to automatically move axially after being rotated into place. The telescopic rod can be made by an electric push rod, a hydraulic rod, etc.

[0033] It should be explained here that, in this specification, terms such as first and second are only used to distinguish one feature from another, and do not mean that there is a certain relationship or order between these technical features. The terms "including" and "comprising" refer to the inclusion of one or some technical means or features, specifically meaning that there are other existing or non-existing technical features that have not been included. The discussion in the above embodiments is only a representative example for the present invention, and is by no means the only restrictive constraint feature. A person of ordinary skill in the art should understand that, without departing from the technical content recorded in all the claims of this application, some simple substitutions and modifications can be made, thereby changing or becoming equivalent to other specific embodiments and application scenarios. However, no matter how the adaptability is changed, these embodiments will inevitably fall within the scope of protection of the present invention.
