[0040] Example 1

[0041] Directions such as front and back in the text are based on the main view of the vending machine.

[0042] See also Figures 1 to 17A vending machine comprises a housing 1, a door 2 disposed on one side of the housing 1, a movably mounted cargo cover 21 on the door 2, and an anti-theft mechanism disposed on the back of the cargo cover 21. The anti-theft mechanism prevents unauthorized users from accessing the stored items in the vending machine by pushing open the cargo cover 21. A cargo storage space 10 is provided at the bottom of the housing 1 near the door 2. Multiple vending machine conveyor modules are disposed within the housing 1 for delivering goods to the cargo storage space. The vending machine is used to sell goods packaged in boxes, such as playing cards. The items contained within the regular square boxes are not limited to entertainment products, but can also include tools, food, and other daily necessities closely related to consumers' lives. During operation, goods fall from the vending machine conveyor modules and then fall into the cargo storage space. A customer pushes open the cargo cover and retrieves the goods from the cargo storage space. After the customer removes the purchased items from the cargo storage space (also referred to as the pickup space), the cargo cover returns to its original position, closing the pickup port of the pickup space.

[0043] In the embodiment, there are a total of 24 conveyor channel modules (hereinafter referred to as modules) of the vending machine (it should be noted that the number of conveyor channel modules in this embodiment is only exemplary, and the number can be adjusted according to the sales scenario, for example, it can be 6 or 10 or 15 or 48 or any other number), divided into three rows, with 8 modules arranged in each row. The four corners of the bottom of the casing are respectively provided with base feet to prevent the bottom of the vending machine from directly contacting the ground. Inclined structures are respectively provided on the left and right sides of the cargo space, so that the goods can enter the middle of the cargo space after falling, which is convenient for picking up the goods.

[0044] In the embodiment, the anti-theft mechanism includes an auxiliary limiting portion disposed on the back of the cargo cover 21, and an anti-theft limiting portion disposed on the back of the door 21 for limiting the cargo cover. The auxiliary limiting portion includes triangular plates 31 on either side, and an inclined plate 32 located between the two triangular plates 31. The anti-theft limiting portion includes end plates 41 on either side, and an intermediate plate 42 disposed between the end plates 41. The end plates 41 and the intermediate plate 42 form a U-shaped component, and the top and bottom of the intermediate plate 42 near the cargo cover 21 are both provided with folded edges 421. Pushing the cargo cover to flip allows the removal of goods from the cargo space (goods that have fallen from the vending machine's conveyor channel module). During the flipping process, the auxiliary limiting portion abuts against the anti-theft limiting portion, preventing the cargo cover from further flipping. This prevents customers from accessing the goods for sale in the vending machine except for normal pickup. The design of the auxiliary limiting portion ensures that the cargo cover opens at a sufficient angle for customers to retrieve goods, while also providing better control over the flipping angle of the cargo cover, resulting in excellent overall anti-theft performance and enhanced safety. In addition, the folded edge makes it difficult for people to be injured during the installation of the anti-theft limit part, and reduces the damage to the cargo cover when the cargo cover hits the anti-theft limit part during use.

[0045] In the embodiment, the conveyor channel module of the vending machine has a mounting plate 51 (the mounting plate is connected to the casing, and the 8 modules arranged in each row share a common mounting plate, that is, the mounting plate of each module is in the form of an integral mounting plate), a conveyor belt mounting frame 52 is provided on the mounting plate 51 (the conveyor belt mounting frame and the mounting plate can be connected by snaps or bolts), a conveyor belt 53 is provided at the conveyor belt mounting frame 52 (the installation position of the motor driving the conveyor belt is set as needed, for example, the installation position is at the front of the conveyor belt, and reference can be made to the prior art), a material diverting structure is provided on the conveyor belt 53, and vertical plates 54 are respectively provided on both sides of the conveyor belt mounting frame 52, a front cargo stop 55 is provided on the front side of the vertical plate 54, and a rear cargo stop 56 is provided on the rear side, and there is at least one cargo cavity between the two vertical plates 54. The front cargo block is a plate-like structure used to block the front of the goods. The rear cargo block can be a plate-like structure or a folding plate installed on the rear side of the vertical plate (the folding plate is perpendicular to the vertical plate). The two folding plates form a rear cargo block (this form is adopted in the embodiment) to form a rear cargo block to block the rear of the goods. The goods at the bottom of the cargo cavity fall onto the conveyor belt (supported by the conveyor belt mounting bracket). The material-diverting structure is in the form of a horizontal block fixedly connected to the conveyor belt. When the conveyor belt is in operation, the material-diverting structure pushes the goods forward and outputs them from the conveyor belt exit position and into the cargo space.

[0046] In the embodiment, there are two cargo cavities, namely the front cargo cavity and the rear cargo cavity. An L-shaped partition bar 541 that can be adjusted up and down is provided between the two cargo cavities. Among them, the material-diverting structure includes a first material-diverting structure 531a and a second material-diverting structure 531b. Taking the conveyor channel module on the leftmost side of the middle row as an example, there are two partition bars, which are respectively installed on the vertical plate on the left and the vertical plate on the right. The partition bars are detachable (detachable installation methods include but are not limited to screw installation) for easy adjustment. Since the thickness of goods of different specifications varies, the spacing between the bottom of the partition bar and the conveyor belt is adjusted to accommodate the passage of goods of different thicknesses, thereby improving the versatility of the vending machine.

[0047] In this embodiment, the spacer 541 comprises a first arm 541a and a second arm 541b that are perpendicular to each other. A cladding plate 541c is positioned on one side of the second arm 541b, connecting the cladding plate 541c and the second arm 541b via an arcuate bend 541d. Multiple mounting holes are provided on the first arm to facilitate installation and adjustment. The cladding plate and the second arm can be deformed to a certain extent, preventing them from falling out when not secured in the installation gap, thus enhancing ease of installation and adjustment.

[0048] In the embodiment, convex portions are provided on both sides of the conveyor belt mounting frame 52 near the front cargo cavity, and the convex portions have a feed oblique section 532a, a top material transverse section 532b and a discharge oblique section 532c which are arranged in sequence. When the goods at the bottom of the front cargo cavity fall onto the conveyor belt (carried by the conveyor belt mounting frame), the top height of the goods at the bottom of the front cargo cavity is higher than that of the goods at the bottom of the rear cargo cavity. When the material-diverting structure (the first material-diverting structure or the second material-diverting structure) pushes the rear goods (the goods at the bottom of the rear cargo cavity), in addition to pushing the goods at the bottom of the front cargo cavity at the same time, it will not push the goods above the goods at the bottom of the front cargo cavity (avoiding the situation of 1 pushing 2, that is, 1 product at the bottom of the rear cargo cavity pushes out 2 products in the front cargo cavity at the same time. This is because the box size error and other reasons can easily cause the upper edge of the box of the rear product to hit the product box above the front product, thereby causing a 1-push-2 situation. At this time, the vending machine will output 2 products when only one product is purchased, causing certain economic losses to the supplier), thereby improving the stability and reliability of the sales process.

[0049] In this embodiment, the front portion of the conveyor belt mounting bracket 52 has a downward extension 521 with a structural hole. When the vending machine conveyor channel module is installed, the downward extension acts as a position limiter to prevent the module from leaning backward after installation, which would create an excessive gap between the goods in the front cargo cavity and the front cargo barrier and affect the normal operation of the module.

[0050] In this embodiment, lugs 542 are provided between adjacent vending machine conveyor channel modules. These lugs 542 are connected to corresponding vertical panels. Between adjacent modules, the lugs are located on the vertical panel of the module located to the right (i.e., the left vertical panel of the module located to the right). During module installation, the lugs help limit the position of adjacent modules, preventing them from being installed too close together and causing contact between adjacent spacers, which could affect proper operation.

[0051] In the embodiment, a tilted discharging platform 533 is provided at the discharging position of the conveyor belt 53, and the discharging platform 533 is connected to the conveyor belt mounting frame 52. The design of the discharging platform is conducive to the dropping and discharging of goods.

[0052] Working principle: This vending machine is used for goods sold in the form of packaging, such as playing cards. The front cargo cavity and the rear cargo cavity are used to place (stack) goods respectively.

[0053] The vending machine has multiple modules. During the selling process, the module with goods is selected to sell the goods (the goods are output and dropped into the storage space).

[0054] For ease of description, within a single module, the cargo at the bottom of the front cargo cavity is referred to as A1, the cargo above A1 is referred to as A2, the cargo at the bottom of the rear cargo cavity is referred to as B1, and the cargo above B1 is referred to as B2. Each quarter-turn (quarter-stroke) of the conveyor belt completes one load and drops into the cargo compartment. A full rotation of the conveyor belt completes four loads. Figure 18 In addition, because there is a distance between the goods and the conveyor belt and the goods are carried by the conveyor belt mounting frame, during the movement of the conveyor belt, the goods will only move when the material shifting structure (the first material shifting structure and the second material shifting structure) acts on the goods.

[0055] During the first sale, the conveyor belt rotates for the first time, and the first material shifting mechanism pushes B1, causing A1 to be ejected (the two items are adjacent, so pushing the item at the rear will move the item at the front). The item then falls into the storage space. The customer then pushes open the lid and retrieves the item from the storage space. During this process, the auxiliary limiter cooperates with the anti-theft limiter to limit the lid's tilt angle, preventing the customer from accessing items outside the storage space (the items waiting to be sold in the vending machine). At this point, B2 falls to the bottom of the rear cargo cavity.

[0056] During the second sale, the conveyor belt rotates a second time, and the first material-discharging mechanism pushes B1 out, causing B1 to fall into the cargo space. The customer can then push open the cargo cover and take it out. At this point, A2 falls to the bottom of the front cargo cavity.

[0057] During the third sale, the conveyor belt rotates for the third time, and the second material-dispensing mechanism pushes B2 to output A2. The A2 product falls into the cargo space, and the customer pushes open the cargo cover to take out the A2 product.

[0058] During the fourth sale, the conveyor belt rotates for the fourth time, and the second material-discharging mechanism pushes B2 out, causing the B2 goods to fall into the cargo space, and the customer pushes open the cargo cover to take out the B2 goods.

[0059] During subsequent sales, the above sales process is repeated, that is, the first material-shifting structure and the second material-shifting structure act on the goods in turn, pushing the goods to be output and falling into the cargo storage space.

[0060] Example 2

[0061] The basic scheme is the same as the vending machine in Example 1, except that the conveyor belt mounting frame 52 is equipped with a first sensor 534a for detecting whether goods have been discharged, a second sensor 534b for detecting whether goods are on the conveyor belt, and a third sensor 534c for detecting whether restocking is needed. The first, second, and third sensors, as well as the conveyor belt, are all connected to a control board. The control board can be installed inside the vending machine. The first sensor can be installed in front of the discharge platform, the second sensor can be installed on the side of the conveyor belt, and the third sensor can be installed on the upper rear side of the conveyor belt to detect a piece of goods above the goods at the bottom of the rear cargo cavity. If the third sensor detects that there is no goods, it prompts restocking (the vending machine is equipped with a display screen connected to the control board, and the restocking prompt is displayed on the display screen). If the first sensor detects that goods have fallen, the control board controls the conveyor belt to stop. The second sensor is used to detect whether there are goods on the conveyor belt. During sales, the control board uses the second sensor to determine whether a module has goods and the first sensor to determine whether goods have been discharged. After the goods have been discharged, the conveyor belt stops and the third sensor determines whether a module needs to be restocked.

[0062] Example 3

[0063] This embodiment is the same as the first embodiment, except that Figure 19The base 11 can have an axially upward threaded hole at its bottom. The threaded hole is not only used to assemble the shock-absorbing bolt, but also serves as a transfer space for the spacing release channel and establishes conditions for the establishment of a passage for the entire release channel. A reverse shock-absorbing bolt 12 is installed in the threaded hole. The shock-absorbing bolt not only has a shock-absorbing effect, but also has the effect of adjusting the installation level of the vending machine because the shock-absorbing bolts are evenly distributed at the four corners of the vending machine. A shock-absorbing sleeve 13 with a wall thickness of 0.3-0.7 cm is provided at the bottom of the shock-absorbing bolt. The inventor found in the use of similar products on the market that the inside of the vending machine may have a shock-absorbing effect due to various factors (such as leakage of the product itself, condensation of water in the installation environment, etc.). When the problem of water accumulation occurs, maintenance personnel are often unable to discover the problem of liquid accumulation in time. If the accumulated liquid is deposited in the pickup space (i.e., the cargo space) for a long time, it may at least affect the soaking and damage of the purchased items of consumers, and at worst, it may affect the internal electronic components and other problems, thereby affecting the service life and working stability of the vending machine. In view of this, the inventor relies on the shock-absorbing structure to achieve a good anti-seismic effect of the vending machine when avoiding external vibrations (not only regular vibrations occurring in subway lines, but also occasional vibrations such as external blasting vibrations in the environment). Taking into account that the accumulated liquid is usually at the bottom of the vending machine, such as the cargo space, the inventor sets a liquid release channel 11-1 in the base that communicates with the cargo space. At this time The accumulated liquid can be released by connecting the accumulated liquid release channel 11-1 with the threaded hole adapted for the shock-absorbing bolt. More importantly, since such a structure often needs to prevent small objects such as external mosquitoes from entering, the shock-absorbing bolt 1 is provided with a secondary cache release channel 12-1 connected to the accumulated liquid release channel 11-1. The upper part of the secondary cache release channel 12-1 is symmetrically provided with a straight channel connected to the accumulated liquid release channel. The vertical part of the secondary cache release channel has a funnel-shaped collection part with a large upper part and a small lower part connected to the straight channel. Below the funnel-shaped collection part is an equal-diameter channel of the vertical part. The bottom of the vertical part is connected to the lower straight channel set by the shock-absorbing bolt. The labyrinthine structure prevents any object from passing directly through the labyrinthine passage to the cargo pickup space. The outlet of the lower straight passage is just covered by a shock-absorbing sleeve. This design can firstly open the entire liquid release channel after the shock-absorbing sleeve is peeled off the shock-absorbing bolt, thereby efficiently draining the accumulated liquid in the cargo space. When the shock-absorbing sleeve is on the shock-absorbing bolt, the entire release channel is open but the outlet is not open (equivalent to the valve not being open). The advantage is that the accumulated liquid can enter the release channel. The operator only needs to peel off part of the shock-absorbing sleeve to observe the indicator at the outlet of the release channel (such as the pre-water color-changing paint applied to the shock-absorbing sleeve, or the anhydrous copper sulfate placed at the outlet) to promptly determine whether there is a water problem. Since the shock-absorbing sleeve is made of rubber, small holes can also be punched in the rubber material to connect to the release channel. This can avoid the problem of negative pressure inside the vending machine and difficulty in opening the cargo cover (in this case, the shock-absorbing sleeve cannot function as a valve switch).

[0064] Example 4

[0065] exist Figure 20-21 The vending machine conveyor channel module is given in the figure (part of the structure is omitted). The driving motor 53a of the driving conveyor belt 53 in the core module can be a front-driven conveyor belt or a rear-driven conveyor belt. This embodiment adopts the structure of the front-driven conveyor belt. The vending machine conveyor channel module is used to convey two stacks of boxed products (arranged in the front cargo cavity and the rear cargo cavity respectively, and the two cavities are actually connected, which is convenient for space conservation and more convenient for operators to place goods). The vending machine conveyor channel module includes a cargo channel carrier (i.e. the conveyor belt mounting frame 52 mentioned above, etc.), the cargo channel carrier is provided with a conveyor belt 53 driven by a power device (i.e. a driving motor), and the vending machine conveyor channel module is provided with a material-diverting structure (also known as a push rod assembly) installed on the conveyor belt and sequentially pushing out the box-shaped product at the bottom of the two stacked products. The material-diverting structure can be a block body with cantilever wings 531-1 at both ends of the block body. The end surface of the cantilever wings will not contact the track bodies distributed on both sides of the conveyor belt and the lower surface will not contact the conveyor belt, thereby improving the smoothness of transportation and avoiding interference. The problem is that the carrier is provided with a horizontal conveying track 532d adjacent to the conveyor belt. The horizontal conveying track prevents the goods from directly contacting the conveyor belt, but allows the goods to be placed on the horizontal conveying track, and relies on the push rod assembly to realize the horizontal pushing forward of the goods. A box-shaped product horizontal conveying track-changing structure distributed on both sides of the conveyor belt is provided near the output end of the cargo channel carrier. The track-changing structure includes but is not limited to the structural form of the feed oblique section 532a mentioned above. The horizontal conveying track-changing structure is only directly connected to the lifting platform. The lifting platform is a sheet-like form that is the same as the horizontal conveying track-changing structure. Integrally formed with the horizontal conveying track-changing structure, the lifting platform can lift the goods to be output in front and only allow the goods adjacent to it at the back to contact with the bottom of its tail, thereby avoiding the situation of "1 pushes 2". The output part of the lifting platform has an arc-shaped variable height rail 532e, and the front end of the cargo channel carrier is provided with a free-falling platform for goods with a free-falling structure, such as the structural form of the discharge platform 533. The arc-shaped variable height rail is adjacent to the free-falling platform for goods through a gap, and the height of the push rod assembly is greater than the horizontal conveying track, the lifting platform and the horizontal conveying track-changing structure.

[0066] from Figure 20 and 21 It can be seen that the cargo free-fall platform is a slope structure that rises forward from the gap. The cargo free-fall platform has a vertical portion 533a and an inclined portion 533b that smoothly transitions to the vertical portion. As an improvement, see Figure 22The lower end of the vertical portion is provided with an upwardly extending turbulent air duct 533-1 (the turbulent air duct input port is connected to the air supply system, including but not limited to a compressed air supply system, a fan air supply device, and whether it has pressure air supply and normal pressure air supply can be selected according to needs). The turbulent air duct extends to the inclined portion, and the inclined portion is provided with a plurality of turbulent air outlet holes 533-2 communicating with the turbulent air duct near its rear section. The turbulent air duct can be evenly distributed 3-10 on the inclined portion, and the aperture of the turbulent air outlet hole gradually decreases from the inside to the outside. The variable diameter structure can increase the air flow output rate. The inclined portion is provided with a plurality of blowing air outlet holes 533-3 communicating with the turbulent air duct near its front section, and the aperture of the blowing air outlet hole gradually increases from the inside to the outside. This form opposite to the turbulent air outlet hole structure can avoid the high-speed jet from pushing back the goods and slowing down or delaying the goods from falling into the picking space. The angle between the axis of the blowing air outlet and the upper surface of the inclined portion is an acute angle. Through this design, the turbulent air outlet can form a local high-speed jet gas due to the variable diameter structure to lift the box-shaped outer packaging to be output, while the blowing air outlet can not only maintain the cleanliness of the inclined part and avoid negative pressure adsorption of the box-shaped outer packaging, but also allow the box-shaped packaging of the product to be output to quickly lose balance and fall into the pickup space.

All technical solutions that fall within the principles of the present invention fall within the scope of protection of the present invention. For those skilled in the art, any improvements made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
