Description

Technical Field

[0001] The present invention relates to the technical field of self-service vending, and in particular to a self-service convenience store. Background Art

[0002] At present, the retail industry is dominated by large supermarkets and convenience stores. Daily tasks such as receiving, loading, sorting, cleaning, inspection, loss prevention and cashiering require a large number of staff, and labor costs have become one of the heavy burdens of the retail industry. In addition, retail stores, supermarkets, and convenience stores are generally located in commercial and prosperous areas with large traffic, and high rents also increase the cost of the retail industry. With the continuous increase in labor costs and rental costs, the profits of the retail industry are getting lower and lower, which has become a bottleneck restricting the sustainable development of the retail industry.

[0003] The traditional convenience store or supermarket shopping model is that users enter the store to make purchases. The shelf space and aisle space in the store must be in a certain ratio to meet the needs of different user traffic, which greatly occupies the store area and reduces the space utilization rate of the convenience store. When users enter the store and search for products in the store without the guidance of staff, they usually have to spend a lot of time searching and comparing, wasting shoppers' time.

[0004] As intelligent life becomes more and more popular, many traditional manual operations can be completed by machines. At present, the steps of the goods sales process in the retail industry are gradually replaced by automated machines, such as users independently using code scanning to pay, which reduces labor costs. Intelligent operation has high requirements for the design of automated structures. At present, most of the self-service vending methods on the market are stand-alone vending cabinets, with limited product types and insufficient storage of goods. They cannot meet the shopping needs of shoppers, resulting in a low utilization rate of existing self-service vending cabinets. Summary of the invention

[0005] The purpose of the present invention is to provide a self-service convenience store which is convenient for shopping, highly integrated and automated, and has abundant goods.

[0006] In order to achieve the above object, the present invention is specifically implemented through the following technical solutions:

[0007] A self-service convenience store, comprising an integral wall surface and a storage area and a shopping area arranged on both sides of the integral wall surface, the storage area comprising shelves, a plurality of containers horizontally mounted on the shelves, and a plurality of shuttle vehicles movably mounted on the front walls of the containers, a slide rail groove is provided on the front wall frame of the container, a plurality of sets of horizontal conveyor belts are installed inside the container, a universal guide wheel embedded in the slide rail groove of the container is installed on the rear wall of the shuttle vehicle, and the shuttle vehicle moves along the front wall of the container via a moving wheel mounted on the rear wall;

[0008] The integral wall separates the storage area from the shopping area. A plurality of human-computer interaction units are arranged on one side of the shopping area of ​​the integral wall. The human-computer interaction units are used for interactive operations of users to select and pay for goods. A delivery port is opened on the integral wall. Each human-computer interaction unit corresponds to a shuttle vehicle and a delivery port.

[0009] The storage area is equipped with a central processing unit, which is connected to the storage unit, shuttle vehicle and human-machine interaction unit. The central processing unit is used to process shopping data, control equipment operation and inventory statistics of goods, etc.

[0010] The self-service convenience store of the present invention adopts warehouse-style shopping, and divides the store space into a shopping area and a storage area. Shoppers only need to select goods through the human-computer interaction unit in the shopping area, and pick up the goods through the corresponding shopping shuttle, without the need for shoppers to search and pick up goods between shelves themselves, thereby realizing the placement of more types and quantities of goods in a limited store space. Shoppers view and select the required goods through the human-computer interface of the human-computer interaction unit, and meet the shopping needs of different users as much as possible, improve the space utilization rate of the self-service convenience store, and reduce labor costs. For the goods that the user confirms to purchase and pays for, the shuttle in the storage area picks up the goods one by one between the different vertically arranged containers, and delivers them to the shipping port after picking up the goods. During this period, the user only needs to wait for a while, which greatly improves the shopping efficiency.

[0011] To improve space utilization, containers are placed horizontally on the shelves. In order to facilitate picking up goods from the shelves, the universal guide wheels on the rear wall of the shuttle are embedded in the slide rail grooves of the container, and the moving wheels on the rear wall are driven to move along the front wall of the container to achieve vertical wall climbing capabilities, allowing the shuttle to move between vertical containers to the designated container and complete the picking up of goods.

[0012] Furthermore, the container is a rectangular box structure with openings on the front and rear walls, and a shuttle detection device is installed on the front wall, which is used to detect the number of the currently parked shuttle; a number of pushing mechanisms are arranged on the horizontal conveyor belt, and the horizontal conveyor belt is used to push out a corresponding number of goods according to the rotation of the number of goods in the order corresponding to the current shuttle.

[0013] The containers used in the present invention are all of the same size, with openings on the front and back sides. The goods stored in the containers are pushed out from the front side of the containers by the horizontal conveyor belt, and the back side of the containers is a replenishment port. Each group of containers is independently fixed to the shelves by means of latches, which can be easily assembled and disassembled. At the same time, different numbers of containers can be customized and assembled according to store needs and product quantity requirements. The horizontal conveyor belt is installed in the container, and the goods are placed on the horizontal conveyor belt. The installation position of the horizontal conveyor belt reserves space according to the size of different goods.

[0014] Furthermore, the slide rail groove includes a transverse slide rail groove opened along the transverse frame of the container and a vertical slide rail groove opened along the vertical frame of the container, and the transverse slide rail grooves and vertical slide rail grooves of multiple groups of containers are connected respectively. The slide rail groove is used for the shuttle vehicle to move vertically or horizontally on the shelf. In order to realize the smooth operation of the shuttle vehicle between the containers of the entire shelf, the present invention adopts the method of opening the running track of the shuttle vehicle on the front wall of the container, and realizing the flexible operation of the shuttle vehicle by connecting the slide rail grooves.

[0015] Furthermore, the shuttle vehicle includes a rectangular outer box body that penetrates front to back and an inner box body that is installed in the outer box body through a telescopic mechanism and a hinge mechanism.

[0016] The shuttle car used in the present invention is a box structure, which expands the space for holding goods, meets the demand for picking up large quantities of goods orders, and reduces the number of shipments of the same order. The shuttle car structure is an inner and outer double-layer box structure. The outer box supports and installs various driving and detection components, and the inner box is used to directly hold the goods. The inner box is connected to the outer box through a telescopic mechanism and a hinge mechanism, and the flipping of the inner box is achieved by the telescopic push rod of the telescopic mechanism. When the shuttle car reaches the delivery port, the telescopic mechanism is started to flip the inner box to a certain angle so that the opening of the inner box is facing the delivery port, which makes it more convenient for users to pick up goods, and optimizes the human-computer interaction process.

[0017] Furthermore, proximity sensors are installed around the surface of the outer box body, and the proximity sensors are connected to the central processing unit. The proximity sensors are used to detect the proximity between the shuttle vehicles, so as to change the route in time and avoid route conflicts.

[0018] Furthermore, the universal guide wheels are installed at the four corners of the rear wall of the shuttle car and are connected to the shuttle car through a stretching mechanism. The end of the universal guide wheel is embedded in the slide rail groove of the container, and the other end is fixed to the rear wall of the shuttle car. The shuttle car and the slide rail groove of the container are clamped by the stretching force of the front and rear axial direction of the stretching mechanism, thereby increasing the friction between the shuttle car and the front wall of the container to prevent the shuttle car from sliding off the shelf due to gravity.

[0019] The shuttle is provided with a trigger device, which is connected to the telescopic mechanism control. The trigger device is used to detect the position of the delivery port. When the shuttle runs to the delivery port, the trigger device controls the telescopic mechanism to push the upper part of the inner box forward to tilt the inner box and correspond to the delivery port.

[0020] Furthermore, the moving wheels include transverse wheel groups installed on the upper and lower sides of the rear wall of the shuttle and longitudinal wheel groups on the left and right sides; when moving transversely, the longitudinal wheel groups are retracted and the shuttle moves through the transverse wheel groups; when moving longitudinally, the longitudinal wheel groups are lowered and the shuttle moves through the longitudinal wheel groups.

[0021] In order to realize the vertical wall-climbing movement of the shuttle vehicle on the shelf, the shuttle vehicle used in the present invention is clamped in the slide rail groove by sliding wheels and the moving direction is limited, so that the shuttle vehicle can move vertically on the front wall of the container; the shuttle vehicle drives the moving wheels through a motor to realize the forward and reverse movement of the shuttle vehicle. In order to prevent the shuttle vehicle from sliding, retreating or falling due to the smooth surface or gravity when moving vertically, the motor's own stop brake is used to avoid slipping due to the smooth contact surface between the container and the moving wheels.

[0022] Furthermore, a human body proximity switch is installed on one side of the human-machine interaction unit, and the human body proximity switch is connected to the central processing unit. The human body proximity switch is used to wake up the operation interface of the human-machine interaction unit when a human body approaches.

[0023] Furthermore, the containers are divided into normal temperature containers, refrigerated containers and hot drink containers, and a mobile replenishment lift is provided at the back of the shelf.

[0024] Furthermore, the shuttle vehicles used in the present invention can avoid running routes through the control of the central processing unit to avoid conflicts when multiple groups of shuttle vehicles are running at the same time. The central processing unit:

[0025] Receive the product order information of the current human-computer interaction unit;

[0026] Determine the horizontal coordinate X and vertical coordinate Y of the container where the ordered goods are located, and the horizontal coordinate S and vertical coordinate T of the horizontal conveyor belt where the goods are located according to the goods order information;

[0027] According to the order information, a purchasing order is formed, and the shuttle car is driven to move to the container where the goods are located and then stop. The horizontal conveyor belt where the goods in the current container are located is started in turn, and the ordered quantity of goods is pushed into the shuttle car;

[0028] Drive the shuttle to the container at the next coordinate position to continue picking up goods. After completing the picking up of all ordered goods, drive the shuttle to move to the delivery port corresponding to the current human-computer interaction unit for the user to pick up the goods;

[0029] After scanning and confirming that the user has emptied the shuttle's cargo, the shuttle is driven back to its original position, put into standby mode, and then charged.

[0030] The picking process adopted in the present invention is that the central processing unit receives data from the human-computer interaction unit and then processes it, while controlling the shuttle vehicle and the container to operate in coordination, thereby realizing automated and efficient picking.

[0031] Compared with the prior art, the technical solution of the present invention utilizes the flexible control of the shuttle vehicle to travel vertically between the containers, greatly simplifies the mechanical equipment of the self-service vending process, reduces the manpower and space costs, and greatly improves the store's floor efficiency utilization rate; the goods are rich, the intelligent control of the self-service convenience store is improved, the quality and entry and exit of the goods are accurately controlled, and the user's purchasing process is more convenient. Now for vending machines, there is a larger space and a variety of temperature zone inventories, as well as a flexibly constructed box, which fully utilizes the space, minimizes cargo damage, and does not have credit risks.

DETAILED DESCRIPTION

[0037] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figure 1 As shown, a self-service convenience store of the present invention includes an integral wall 1 and a storage area and a shopping area arranged on both sides of the integral wall 1. Preferably, the integral wall 1 can be a glass wall made of transparent material, so that users can observe the situation of picking up goods in the storage area. The storage area is used to store goods and other equipment. The storage area includes shelves 2, a number of containers 3 horizontally mounted on the shelves 2, and a number of shuttles 4 movably mounted on the front wall of the containers 3. A slide rail groove 31 is provided on the frame of the front wall of the containers 3, and multiple groups of horizontal conveyor belts 32 are installed inside the containers. The rear wall of the shuttle 4 is installed with a universal guide wheel 41 embedded in the slide rail groove 31 of the container 3, and the shuttle 4 moves along the front wall of the container through the moving wheels 42 installed on the rear wall.

[0039] The integral wall 1 separates the storage area from the shopping area. The shopping area is the area that users directly contact after entering. Several human-machine interaction units 5 are set on one side of the shopping area of ​​the integral wall 1. The human-machine interaction units 5 are used for interactive operations of users to select and pay for goods. The integral wall 1 is provided with a delivery port 6. The delivery port 6 is located on one side or the bottom of the human-machine interaction unit 5. It is used for the final delivery position of the current human-machine interaction unit. After the shuttle 4 completes the pickup, it returns to the delivery port 6 to wait for shoppers to take away the goods. Each human-machine interaction unit 5 corresponds to a shuttle 4 and a delivery port 6 in a one-to-one numbered manner, so that the human-machine interaction unit 5 and the shuttle 4 can be served in correspondence, avoiding confusion in order processing when multiple human-machine interaction units 5 place orders at the same time, and improving the efficiency of picking up goods.

[0040] The storage area is provided with a central processing unit 7, which is respectively connected to the container 3, the shuttle 4 and the human-computer interaction unit 5 for processing shopping data, controlling equipment operation and inventory statistics of goods. The order processing process of the central processing unit 7 may specifically include the following steps:

[0041] S1. Receive the product order information of the current human-computer interaction unit;

[0042] S2. Determine the horizontal coordinate X and the vertical coordinate Y of the container where the ordered goods are located, and the horizontal coordinate S and the vertical coordinate T of the horizontal conveyor belt where the goods are located according to the goods order information;

[0043] S3. According to the purchase order, the shuttle car is driven to move to the container where the goods are located and then stops, and the horizontal conveyor belt where the goods in the current container are located is started in turn to push the ordered quantity of goods into the shuttle car;

[0044] S4, drive the shuttle to move to the container at the next coordinate position to continue picking up the goods. After completing the picking up of all the ordered goods, drive the shuttle to move to the delivery port corresponding to the current human-computer interaction unit, and the user picks up the goods;

[0045] S5. After scanning and confirming that the user has emptied the shuttle vehicle of cargo, the shuttle vehicle is driven to return to its original position, standby, and charge.

[0046] A human proximity switch 49 is installed on one side of the human-machine interaction unit 5, and the human proximity switch 49 is connected to the central processing unit 7, and is used to wake up the interface of the human-machine interaction unit 5 when a shopper approaches. During the period when no one is using it, the machine is in a dormant state, the shuttle 4 is in a charging position, and the dynamic or static display of the human-machine interaction unit 5 displays brand advertisements and LOGO. When the user approaches, the human proximity switch 49 is awakened, and the corresponding touch screen of the human-machine interaction unit 5 displays the main shopping interface. After the user clicks on all the purchased goods through the screen of the human-machine interaction unit 5 and successfully pays through the available payment method, the machine starts to operate. The shuttle 4 receives the purchase instruction and starts the running program following the best planned route.

[0047] The entire shopping process includes the shopper approaching to wake up the machine, the customer clicks on the desired goods and corresponding needs, and after the order is successfully placed, the machine extracts the goods in order according to the best path according to the goods placement, and finally extracts all the goods, tilts the goods out to the delivery port, and the customer takes the goods and closes the delivery port door to complete the transaction. You can also order goods through the mobile phone program and scan the code at the window to pick up the goods. For the first time shopping, you only need to complete the registration and link WeChat or Alipay.

[0048] like Figure 2 As shown, the container 3 is a rectangular box structure with openings on the front and rear walls. It can be several boxes of the same size, with openings on the front and rear sides of the boxes. The goods stored in the container 3 are pushed out from the front side of the container 3 by a horizontal conveyor belt, and the rear side of the container 3 is a replenishment port. The four side edges of the container 3 are connected to the shelf installation by means of latches or slide rails, which is convenient for loading and unloading and replacing containers. The shelf 2 is a frame structure, which can be built vertically, stacked upwards, spliced ​​to the left and right, or extended backward to achieve expansion. A shuttle detection device 32 is installed on the front wall of the container 3. The shuttle detection device 32 is used to scan and detect the number information of the currently parked shuttle 4, and start to retrieve the order information in the central processing unit 7 according to the number of the shuttle 4, and push and output the corresponding goods accordingly to prevent confusion when multiple orders are picked up at the same time.

[0049] A plurality of push mechanisms 34 are arranged on the horizontal conveyor belt 33 of the container 3, and each push mechanism 34 is placed with a unit of goods. The horizontal conveyor belt 33 is used to rotate according to the number of goods in the order corresponding to the current shuttle 4, and the push mechanism 34 outputs the same number of goods, and pushes the goods corresponding to the order into the shuttle 4. When the goods on the shelf are transported to the shuttle 4 under the drive of the horizontal conveyor belt 33, a scanning device is installed on the inside of the shuttle 4 to detect the status of the goods and scan the goods information. After confirmation, it can start to the next target node.

[0050] The slide rail groove 31 opened on the front wall frame of the container 3 includes two horizontal slide rail grooves 311 opened along the horizontal frame of the container 3 and a vertical slide rail groove 312 opened along the vertical frame of the container 3. Multiple groups of horizontal slide rail grooves 311 and vertical slide rail grooves 312 of the container 3 are respectively connected to form an integral through horizontal track and vertical track on the front surface of the shelf 2. The shuttle vehicle 4 can pick up goods in sequence along the track of the slide rail groove 31 according to the instructions of the central processing unit 7.

[0051] like Figure 3As shown, the shuttle 4 includes a rectangular outer box 43 that penetrates from front to back and an inner box 46 installed in the outer box 43 through a telescopic mechanism 44 and a hinge mechanism 45. The inner box 46 is a column box structure with a fan-shaped longitudinal section, and its arc surface is open. One side of the inner box 46 is connected to the bottom surface of the outer box through the telescopic mechanism 44, and the other side is made of transparent material. A hinge mechanism 45 connected to the bottom edge of the outer box 43 is installed along the fan-shaped column axis of the inner box 46. The angle of the fan-shaped longitudinal section of the inner box 46 is 70° to 100°, preferably 80°.

[0052] Preferably, the shuttle 4 is provided with a trigger device for detecting the position of the delivery port. When the shuttle 4 moves to the delivery port, the trigger device controls the telescopic mechanism 44 to flip the inner box 46 forward at a certain angle and push it out, so that the inner box 46 is tilted and corresponds to the delivery port 6. The bottom of the inner box 46 is tilted from the rear side to the front and downward, that is, the shuttle 4 uses the rear side corresponding to the container 3 as the cargo input side and tilts inward, so that the cargo that enters the shuttle 4 first tilts toward the inside of the car, preventing the cargo from sliding out or getting stuck between the shuttle 4 and the container 3, and at the same time, the cargo that enters the shuttle later can easily push the previous cargo into the car to leave space for placement.

[0053] like Figure 4 As shown, universal guide wheels 41 are installed at the four corners of the rear wall of the shuttle 4, and four sets of moving wheels 42 are installed on the four sides. The universal guide wheel 41 is connected to the shuttle 4 through a stretching mechanism 48. The end of the universal guide wheel 41 is embedded in the slide rail groove 31 of the container 3, and the other end is fixed on the rear wall of the shuttle 4. The front-to-back axial tensile force of the stretching mechanism 48 increases the clamping force between the shuttle 4 and the slide rail groove 31 of the container 3, increases the friction between the shuttle 4 and the front wall of the container 3, and prevents the shuttle 4 from slipping due to gravity. After the universal guide wheel 41 is embedded in the slide rail groove 31 on both sides of the container 3, it can move horizontally and vertically. Preferably, the inner cross section of the slide rail groove 31 is a hollow "convex" shape. The universal guide wheel 41 is embedded in the "convex" shaped space of the slide rail groove 31, and the "convex" shaped top of the moving wheel 42 is slidably installed to provide a moving guide rail for the movement of the shuttle.

[0054] Preferably, the moving wheels 42 include a transverse wheel set 421 installed on the upper and lower sides of the rear wall of the shuttle 4 and a longitudinal wheel set 422 on the left and right sides; when moving transversely, the longitudinal wheel set 422 is retracted, and the shuttle 4 moves laterally through the transverse wheel set 421; when moving longitudinally, the longitudinal wheel set 422 is lowered, and the shuttle 4 moves vertically through the longitudinal wheel set 422.

[0055] The moving wheel 42 can also change direction in the following manner: when the shuttle 4 is converted from horizontal to vertical, the shuttle 4 uses the horizontal wheel set 421 to move along the horizontal guide rail to the cross node, senses the node signal coordinates and stops, the longitudinal wheel set 422 lands, and the horizontal wheel set 421 is retracted, and the shuttle can be started in the longitudinal direction and continue to move; when the longitudinal direction is converted from horizontal, the shuttle 4 uses the longitudinal wheel set 422 to move along the longitudinal guide rail to the cross node, senses the node signal coordinates and stops, after the horizontal wheel set 421 lands, the longitudinal wheel set 422 is retracted, and the shuttle 4 can be started in the horizontal direction and continue to move. When the shuttle is in a stable static state of reversing or picking up goods, the horizontal wheel set 421 and the longitudinal wheel set 422 are both in the landing state, so that the shuttle is stable on the slide rail groove 31. That is, when stationary, the transverse wheel set 421 and the longitudinal wheel set 422 are simultaneously attached to the slide rail groove 31 to increase the direct friction between the shuttle and the slide rail groove 31. For example, after the transverse wheel set 421 that can only achieve transverse rotation is stabilized, the friction in the longitudinal direction, i.e., the vertical direction, can be increased to prevent the shuttle from slipping due to gravity. After the longitudinal wheel set 422 that can only achieve longitudinal rotation is stabilized, the so-called periodic lateral left and right swinging of the shuttle can be avoided, thereby ensuring that the shuttle can be stable on the slide rail groove 31 when changing direction or picking up goods.

[0056] Furthermore, an anti-skid device may be provided on the moving wheel 42 to further increase the friction between the shuttle vehicle 4 and the front wall of the container 3 .

[0057] The size of the outer box 43 is slightly smaller than the size of the outer wall around the container 3 to prevent a gap from being left when the two shuttles 4 run in parallel. The bottom of the inner box 46 is inclined from the rear side to the front and downward, and the height of the rear side of the bottom of the inner box 46 that docks with the container 3 is consistent with the height of the bottom of the container 3. The container 3 body has a frame and a slide rail groove 31 structure, and its bottom has a certain height. The bottom of the rear opening side of the inner box 46 of the shuttle 4 docking with the container 3 is perfectly connected with the bottom of the container 3 to prevent the goods from falling into the gap between the shuttle 4 and the container 3 when pushing. The transverse wheel group 421 and the longitudinal wheel group 422 of the shuttle 4 are driven by two sets of travel motors respectively, and travel vertically or horizontally along the track on the surface of the container 3. The travel motor is embedded and installed at the bottom of the shuttle 4, and can be installed in the vacant position between the bottom of the outer box 43 and the bottom of the inner box 46, such as the rear side of the bottom.

[0058] Proximity sensors 47 are installed around the outer box 43 to detect the proximity of the shuttle 4 to other shuttles and transmit the information to the central processing unit 7. The proximity between the shuttles can be monitored in time, and the routes can be changed in time to avoid collision. The central processing unit 7 can control the movement of the shuttle 4 by the following method, and the description of the "first direction" and "second direction" is but does not correspond to the specific horizontal or vertical direction:

[0059] When the distance between two shuttles running toward each other along the first direction of the slide groove is less than the width of the container in that direction, the shuttle closest to the second direction of the slide groove retreats to the nearest intersection of the slide grooves, and continues to run along a trajectory with a coordinate minus one in the second direction while the coordinate in the first direction remains unchanged, that is, it moves downward or leftward by a distance of a container width and then continues to move forward;

[0060] When one of the two shuttles on the slideway groove along the first direction moves and the other stops, when the distance between the two shuttles is less than the width of the container in that direction, the shuttle in the moving state retreats to the nearest intersection of the slideway grooves and continues to run in the second direction with a trajectory whose coordinates are reduced by one and whose coordinates in the first direction remain unchanged, that is, it moves downward or to the left by a distance of a container width and then continues to move forward. This avoids the problem of route overlap when two or more shuttles are running at the same time.

[0061] When the shuttle 4 is moving, the screen placed in front of the customer can push advertisements and simultaneously display the moving status of the shuttle 4 and the purchase countdown.

[0062] After the shuttle 4 completes the purchase, it immediately returns to the delivery port 6 corresponding to the order by the shortest path. After the shuttle 4 stops, the telescopic mechanism 44 is activated to tilt the inner box 46 outward and correspond to the delivery port 6. The window baffle is opened, and the customer takes out the goods. The customer can choose whether to pack the goods in a shopping bag. After the goods are picked up, the sensor detects whether the inner box 46 of the shuttle 4 is empty, and the window can be closed to complete the shopping. The inner box 46 of the shuttle returns to its original state, and the shuttle 4 returns to the charging state.

[0063] Preferably, the containers 3 are divided into normal temperature containers, refrigerated containers and hot drink containers for distinguishing and placing various types of goods. A mobile replenishment elevator 8 is provided at the rear side of the shelf 2 for replenishing the containers from the rear of the shelf 2.

[0064] The specific embodiments of the present invention are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
