[0037] The auxiliary unit comprises a connecting rod 101, a stop block 102 and a connecting rope 103; two left-right symmetrical connecting rods 101 are slidably installed on the inner wall of the self-service vending machine 1, and each connecting rod 101 is movably connected with the inner wall of the self-service vending machine 1 by a spring; one stop block 102 is fixedly connected to each connecting rod 101; a plurality of protrusions 10201 are arranged on each stop block 102, and each protrusion 10201 is made of a deformation material; two left-right symmetrical connecting ropes 103 are fixedly connected to the goods taking tray 1002 of the self-service vending machine 1, and each connecting rod 101 is movably connected with the goods taking tray 1002 by the connecting rope 103; the stop block 102 is used to extrude the buffer plate 4, so as to increase the space between the buffer plate 4 and the goods taking tray 1002 of the self-service vending machine 1, and the goods will move away from the goods taking tray 1002 by the backward concave of the buffer plate 4, so as to prevent the goods from being stuck behind the goods taking tray 1002 when the customer takes the goods, and to prevent the goods taking tray 1002 from being difficult to open.

[0038] It also includes a storage box 5; the storage box 5 is slidably installed inside the self-service vending machine 1, and the storage box 5 is located under the cargo aisle; the rear side of the buffer plate 4 is fixedly connected to the front side of the storage box 5; the storage box 5 is connected to the first drive component, and the storage box 5 is driven by the first drive component to move back and forth in the self-service vending machine 1; expired goods are temporarily stored in the storage box 5, thereby preventing customers from purchasing goods that are about to expire, affecting the customers' taste, and avoiding food safety problems.

[0039] The first driving component includes a micro electric crawler 104 and a driving member 105; a plurality of micro electric crawlers 104 are fixedly connected in the self-service vending machine 1, and a plurality of limit blocks 2 are fixedly connected to the corresponding micro electric crawlers 104; with the view from left to right as the reference, the micro electric crawler 104 drives the adjacent aisles to rotate clockwise, thereby completing the pushing of goods, causing the goods to fall onto the buffer plate 4 for customers to pick up; a driving member 105 is fixedly connected to the rear side of the self-service vending machine 1, and the driving member 105 is an electric push rod; the output end of the driving member 105 is fixedly connected to the storage box 5, and the storage box 5 is driven to move forward by the driving member 105, and the micro electric crawler 104 is controlled to rotate, so that expired goods fall from the limit blocks 2 into the storage box 5 below the aisle, thereby realizing the collection of expired goods by the storage box 5.

[0040] The following describes the delivery process of the vending machine 1: Most communities have vending machines 1 for selling various foods, but most existing vending machines 1 use spring channels to sell goods. For soft-packaged drinks, such as fresh milk, the packaging is easily crumpled during the rotating delivery process of the spring channel, causing it to be stuck in the spring channel and unable to fall off. Even the packaging is easily entangled by the spring, causing damage, causing the liquid inside the packaging to flow onto the channel, which is difficult to clean. To avoid the above situation, first, the goods with a short shelf life are recorded into the Internet of Things module inside the vending machine 1 by the replenishment staff. After the recording is completed, the cabinet door 1001 of the vending machine 1 is opened, and then the replenishment staff pulls out a row of channels and replenishes the goods. The bagged fresh milk and other goods are placed between the corresponding limiting blocks 2 according to the recorded information. When the goods are replenished, the cabinet door 1001 is closed, and then when a customer needs to buy bagged fresh milk and places an order, the corresponding goods channel is controlled by the Internet of Things module inside the vending machine 1. From left to right, the corresponding micro electric track 104 drives the adjacent limiting block 2 to rotate clockwise, wrapping the bagged fresh milk with the adjacent limiting block 2, and moving the bagged fresh milk forward with the micro electric track 104, thereby preventing the bagged fresh milk from being squeezed during the moving process and avoiding damage to the packaging. When the limiting block 2 is rotated to a downwardly inclined state, the bagged fresh milk is separated from the limiting block 2 and slides down the surface of the limiting block 2 to the lower buffer plate 4. At this time, the micro electric track 104 continues to rotate until the limiting block 2 is pressed by the limiting plate 3 below and gradually deforms to be compressed and folded on the limiting plate 3, thereby improving the space utilization inside the vending machine 1. When the customer places an order, repeat the above steps to achieve the delivery of goods.

[0041] When the goods fall from the channel to the buffer plate 4, the buffer plate 4 deforms due to the impact of the goods, thereby reducing the impact force of the goods falling from a high place. At the same time, since the front end of the buffer plate 4 is inclined downwardly inside the vending machine 1, when it falls onto the buffer plate 4, the goods will slide along the surface of the buffer plate 4 and gradually slide to the lower side of the goods delivery plate 1002 of the vending machine 1, thereby facilitating the customer to take the goods. After the goods fall, the customer pushes the goods delivery plate 1002 inward to take the purchased goods, causing the goods delivery plate 1002 to flip backward, thereby pulling the connecting rope 103 backward and further pulling the connecting rod 101, causing the connecting rod 101 to slide along the connecting rope 103 inside the vending machine 1 in the pulling direction, thereby causing the stop block 102 to press the buffer plate 4, as shown in Figure 2 and Figure 5As shown, the middle part of the buffer plate 4 is recessed backward along the sliding direction of the connecting rod 101, and at the same time, the friction between the stop block 102 and the buffer plate 4 is increased by the protrusion 10201 on the stop block 102, thereby improving the deformation effect of the buffer plate 4, and then increasing the space between the buffer plate 4 and the pickup plate 1002 of the self-service vending machine 1. By recessing the buffer plate 4 backward, the goods follow the buffer plate 4 away from the pickup plate 1002, thereby preventing the goods from being stuck at the rear side of the pickup plate 1002 when the customer takes the goods, making it difficult to open the pickup plate 1002. As the customer continues to push the pickup plate 1002 inward, the spring connected to the connecting rod 101 is compressed to the extreme at this time, and due to the protrusion 10201 on the buffer plate 4 and the stop block 102 Both 10201 are made of deformable material, so when the pickup plate 1002 is opened to a certain angle, the contact part between the buffer plate 4 and the stop block 102 will be recessed backward, so that the stop block 102 passes over the buffer plate 4 and disengages from the left and right sides of the buffer plate 4, so that the stop block 102 no longer squeezes the buffer plate 4. At this time, the buffer plate 4 rebounds and resets, and drives the goods to move to the bottom of the pickup plate 1002, so that it is convenient for customers to take the goods and improves the customer's usage experience. When the customer takes the goods away, the pickup plate 1002 is closed, and the connecting rope 103 is no longer pulled. At this time, the spring connected to the connecting rod 101 also rebounds and resets, and drives the connecting rod 101 and the stop block 102 to pass over the buffer plate 4 and return to their original position.

[0042] Since some commodities have a short shelf life, such as fresh milk, and the replenisher is unable to replace the commodities in time, when some commodities are about to expire, the replenisher inputs the commodity information into the Internet of Things module on the self-service vending machine 1 through the back-end personnel to control the self-service vending machine 1, and starts the corresponding micro electric crawler 104 according to the placement of the commodities, drives the corresponding limit block 2 to rotate, and pushes the commodities that are about to expire away from the aisle. At the same time, the driving member 105 is started to drive the storage box 5 to move forward until the storage box 5 is located below the fallen commodities, and the commodities immediately fall into the storage box 5 for temporary storage, thereby preventing customers from purchasing commodities that are about to expire, affecting the customers' eating taste, and avoiding food safety issues. When all commodities that are about to expire are processed, the driving member 105 is started again to drive the storage box 5 to move back to its original position, so as to prevent the storage box 5 from interfering with the normal purchase of commodities by customers.

[0046] The water supply system also includes a sliding block 205; the sliding block 205 is slidably connected to the buffer plate 4; a scraping block 20501 is provided on the sliding block 205, and the scraping block 20501 is made of a deformable material; a water-absorbing block 20502 is provided on the sliding block 205, and the water-absorbing block 20502 is made of a water-absorbing material; the scraping block 20501 is used to scrape off the stains remaining on the surface of the buffer plate 4 to improve the cleaning effect, and at the same time, the water-absorbing block 20502 is used to wipe and absorb the moisture on the surface of the buffer plate 4 to prevent moisture from being present on the surface of new products picked up by subsequent customers, thereby affecting the customer's purchasing experience.

[0047] The second drive assembly includes a slide rail 206 and an electric slider 207; each of the two placement slots 1005 on the self-service vending machine 1 is fixed with a slide rail 206; each slide rail 206 is slidably connected to an electric slider 207; the two electric sliders 207 are fixed to the front side of the buffer plate 4, and the front side of the buffer plate 4 is driven up and down by the electric slider 207.

[0048] The cleaning process is described in detail below: For some soft-packaged goods, their packaging is easily damaged due to bumps during transportation by the replenisher, and the replenisher cannot check all damaged soft-packaged goods when replenishing. When the customer places an order, the goods fall from the aisle onto the buffer plate 4. Even if the buffer plate 4 reduces the impact force received by the goods during the falling process, due to the damage to some of the packaging itself, the above-mentioned parts of the goods will still break, causing the liquid inside the goods to splash out. In order to avoid the above situation, when the goods fall, the infrared sensor 203 is used to detect in real time whether there is liquid splashing inside the self-service vending machine 1. When stains are detected, the Internet of Things module on the self-service vending machine 1 will prompt the customer to postpone the shipment and wait for minutes. At this time, the water supply machine 201 will be controlled to provide water to the nozzle 202 to rinse the interior of the self-service vending machine 1 and the surface of the buffer plate 4. The water will be discharged through the first through hole 4001 on the buffer plate 4 to prevent excessive water from accumulating on the surface of the buffer plate 4 and affecting subsequent sales. At the same time, the electric slider 207 will be controlled to drive the front side of the buffer plate 4 to move upward until the buffer plate 4 is tilted so that the front side is higher than the rear side, and the buffer plate 4 is in a straight state, so that the damaged goods slide down along the surface of the buffer plate 4 to the storage box 5 Inside, at this time, the nozzle 202 stops spraying water. When the front side of the buffer plate 4 moves upward, the buffer plate 4 itself is twisted and folded to block the sliding block 205. Only when the buffer plate 4 is in a straight state, the buffer plate 4 no longer blocks the sliding block 205. At this time, the sliding block 205 gradually slides along the surface of the buffer plate 4 to the back side of the buffer plate 4 under the influence of its own gravity. The scraping block 20501 is used to scrape off the stains remaining on the surface of the buffer plate 4 to improve the cleaning effect. At the same time, the water on the surface of the buffer plate 4 is wiped and absorbed by the water absorbing block 20502 to prevent the subsequent customers from having water on the surface of the new products taken, which affects the customer's purchasing experience. When the cleaning is completed, the electric slider 207 is controlled to drive the buffer plate 4 to return to its original position. At this time, the sliding block 205 will gradually slide along the surface of the buffer plate 4 toward the front side of the buffer plate 4 according to its own gravity and return to its original position. At this time, the moisture on the surface of the buffer plate 4 is wiped and absorbed again by the water absorption block 20502, thereby improving the cleaning effect of the moisture on the surface of the buffer plate 4. At this time, the Internet of Things module is controlled to start the micro electric crawler 104 on the corresponding ordered product to ship again, providing new products for customers, thereby preventing customers from taking damaged products and causing losses to customers, while avoiding affecting customer emotions and providing customers with a good shopping experience.

[0049] When the customer takes away the goods, at this time the control driving part 105 drives the storage box 5 to move backward, and then the connecting block 5001 of the storage box 5 drives the baffle 1004 to move backward, until the water outlet 1003 is no longer blocked by the baffle 1004, so that the sewage in the self-service vending machine 1 after cleaning is discharged downward through the water outlet 1003 into the communication groove 20401 of the sewage treatment box 204, and then the sewage enters the sewage treatment box 204 through the communication groove 20401 for collection and treatment, when the sewage discharge is completed, at this time the Internet of Things module of the self-service vending machine 1 is controlled to perform drying treatment on the inside of the self-service vending machine 1, so that the inside of the self-service vending machine 1 is kept dry and clean, avoiding food safety problems caused by sewage pollution.

[0052] The separation system further comprises telescopic rods 303; taking the left-to-right view as the reference, the placement plate 302 is combined in a cross shape by a horizontal plate and a vertical plate; the lower side of the placement plate 302 is fixedly connected with four telescopic rods 303; the telescopic rods 303 are moved up and down by the expired goods extruding the placement plate 302, so as to buffer the expired goods during collection, and prevent the expired goods from being broken by impact.

[0053] The placing plate 302 is provided with a plurality of second through holes 30201; the storage box 5 is communicated with the sewage treatment box 204 through a hose; the liquid in the damaged commodity is guided through the second through holes 30201, so that the liquid flowing out of the damaged commodity is discharged into the sewage treatment box 204 after entering the storage box 5, thereby preventing the liquid from remaining in the storage box 5 to intensify the generation of odor.

[0054] The separation system further comprises a drainage plate 304; the communication port of the storage box 5 and the sewage treatment box 204 is located at the left side of the front chamber of the storage box 5; the front chamber of the storage box 5 is fixedly connected with the drainage plate 304 at the lower side, and the left side of the drainage plate 304 is higher than the right side in an inclined shape; thereby improving the efficiency of the liquid flowing to the communication port of the storage box 5 and the sewage treatment box 204, and preventing the liquid from accumulating in the storage box 5 to avoid increasing odor.

[0055] The following is a detailed description of the product separation process: when the product is expired, the control drive 105 drives the storage box 5 to move forward, and the storage box 5 is divided into two chambers, the front and the rear, by the placement plate 302, to collect the expired products and the damaged products separately, thereby preventing the liquid overflowing from the damaged products from contaminating the expired products. Since the expired products are large in number when being processed, when the expired products fall into the storage box 5, if the expired products and the damaged products are in the same chamber, the expired products will squeeze the damaged products previously collected in the storage box 5 during the aforementioned working process, thereby aggravating the damage to the damaged products. The internal liquid flows out, so that the outer surface of the product packaging is covered with liquid, which increases the odor and contaminates other products in the self-service vending machine 1, and increases the workload of the replenisher. At the same time, when the expired product falls into the rear chamber of the storage box 5, the expired product falls on the placement plate 302 and squeezes it, so that the telescopic rod 303 moves up and down, and then drives the placement plate 302 to move up and down, cushioning the expired product when it falls, preventing the expired product from being hit and broken. When the damaged product slides from the buffer plate 4 to the sealing plate 301 of the storage box 5, the sealing plate 301 is squeezed by the damaged product. The damaged goods fall onto the placement plate 302, and the liquid drips down onto the drainage plate 304 through the second through hole 30201 of the placement plate 302. By setting the drainage plate 304 to an inclined shape with the left side higher than the right side, the speed of the liquid flowing to the connection port between the storage box 5 and the sewage treatment tank 204 is increased. To prevent a large amount of liquid from accumulating in the storage box 5 and to avoid the continuous increase of odor, as the expired goods are collected, the telescopic rod 303 is gradually compressed and the placement plate 302 gradually moves downward. When the replenisher handles the expired and damaged goods, as the replenisher gradually takes away the expired goods, the telescopic rod 303 gradually rebounds and resets, and the placement plate 302 gradually moves upward, so that the replenisher does not need to put his hand into the storage box 5, thereby improving its convenience. After the expired and damaged goods are handled, the replenisher cleans the storage box 5 through the nozzle 202 to avoid odor residue and improve the cleanliness of the self-service vending machine 1.

[0056] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
