Description

Technical Field

[0001] This invention relates to the technical field of vending machines, and in particular to a vending machine for displaying items. Background Technology

[0002] Vending machines have become an important method of retail sales in public places, and unattended vending machines (or unmanned vending machines) can greatly increase users' willingness to buy, extend the time dimension of user consumption, and provide merchants with a continuous and stable sales channel. By adding touch screens, buttons, or scanners to smart vending machines to allow users to select the items they want to buy and pay with cash or mobile payment methods, smart vending machines can also be transformed into automated vending machines.

[0003] The existing vending machine includes a cabinet body, which contains multiple placement boards. The bottom inner surface of the cabinet body has a groove, and the inner side of the groove has an opening with a sealing plate inside.

[0004] In the aforementioned technology, when a user purchases an item, the item falls from the shelf into the opening. Because the shelf at the top of the cabinet is relatively high from the bottom of the cabinet, the item is more likely to fall and break when it falls from the shelf. Summary of the Invention

[0005] In order to improve the problem that items are easily damaged when they fall from the display board, this application provides a vending machine for displaying items.

[0006] The present application provides a vending machine for displaying items, which adopts the following technical solution:

[0007] A vending machine for displaying items includes a cabinet body, a cabinet door on the front end of the cabinet body, and multiple placement boards inside the cabinet body, the multiple placement boards being equally spaced along the height direction of the cabinet body. The vending machine is characterized by: a groove being formed on the inner bottom surface of the cabinet body, an opening being formed on the inner side of the groove, a sealing plate being rotatably disposed within the opening, a buffer plate being provided on the inner bottom surface of the groove, and multiple buffer springs being fixed to the bottom surface of the buffer plate, the bottom ends of the buffer springs being fixed to the inner bottom surface of the groove.

[0008] By adopting the above technical solution, when a user purchases items inside the cabinet, the items fall from the placement board onto the buffer board in the groove. By installing a buffer spring below the buffer board, when the items fall onto the buffer board, the buffer board is cushioned by the elastic force of the buffer spring, thereby reducing the possibility of the items falling from the placement board and getting broken.

[0009] Preferably, the top surface of the buffer plate is provided with a push plate, the bottom surface of the push plate is in contact with the top surface of the buffer plate, both ends of the push plate are fixed with sliders, the opposite inner sides of the groove are provided with sliding grooves, the sliders are slidably disposed in the sliding grooves, and the cabinet is provided with a drive mechanism for driving the push plate to move toward the direction of the sealing plate.

[0010] By adopting the above technical solution, when an item on the placement plate falls onto the buffer plate, the drive mechanism drives the push plate to move towards the sealing plate, so that the push plate pushes the item to the opening, making it easier for the user to open the sealing plate and take out the item.

[0011] Preferably, each of the opposite inner sides of the groove is provided with a mounting slot, the driving mechanism includes a screw rotatably mounted between the opposite inner sides of the mounting slot, each end face of the push plate is fixed with a movable block, the movable block is disposed in the mounting slot, the screw passes through the movable block, the screw is threadedly connected to the movable block, and the cabinet is provided with a driving assembly for driving the two screws to rotate.

[0012] By adopting the above technical solution, when an item falls onto the buffer plate, the drive assembly is activated. The drive assembly drives two screws to rotate simultaneously. The screws drive the moving block to move. The moving block drives the push plate to move towards the sealing plate, thereby pushing the item to the opening.

[0013] Preferably, the drive assembly includes synchronous pulleys disposed on the two screws, with a synchronous belt wound around the two synchronous pulleys, and a second motor disposed on the inner side of one of the mounting slots, the output shaft of the second motor being fixedly connected to one end of the screw.

[0014] By adopting the above technical solution, when an item falls onto the buffer plate, motor two is started. The output shaft of motor two drives the screw to rotate, the screw drives the synchronous pulley to rotate, the synchronous pulley drives the synchronous belt to rotate, the synchronous belt drives another synchronous pulley to rotate, and the other synchronous pulley drives the other screw to rotate, so that the two screws rotate simultaneously, causing the screw to drive the moving block to move, and the moving block drives the push plate to move.

[0015] Preferably, pull ropes are fixed on both sides of the sealing plate near the push plate, two parallel side plates are fixed on both sides of the inner side of the cabinet, through holes are opened on both sides of the inner side of the cabinet, a rotating shaft is rotatably installed between the two side plates, a winding roller is provided on the rotating shaft, one end of the pull rope away from the sealing plate passes through the through hole and is fixed to the outer circumference of the winding roller, and a driving component for driving the rotating shaft to rotate is provided on the cabinet.

[0016] By adopting the above technical solution, when the sealing plate is opened, the sealing plate pulls the rope out of the take-up roller. When the item is taken out, the sealing plate is released, and the rotating shaft rotates in the opposite direction under the elastic force of the drive component, causing the rotating shaft to drive the take-up roller to rotate. The take-up roller winds the rope onto the take-up roller. When the take-up roller winds the rope, the rope drives the sealing plate to move, thereby closing the opening.

[0017] Preferably, the driving component includes a coil spring sleeved on the rotating shaft, one end of the coil spring being fixedly connected to the inner side of the cabinet, and the other end of the coil spring being fixedly connected to the outer peripheral surface of the rotating shaft.

[0018] By adopting the above technical solution, when the sealing plate is opened, the sealing plate pulls the rope out of the take-up roller. When the item is taken out, the sealing plate is released, and the rotating shaft rotates in the opposite direction under the elastic force of the coil spring, thereby driving the take-up roller to rotate.

[0019] Preferably, the placement plate includes a shelf, the top surface of which has multiple through slots, two drive rollers are arranged in the through slots, a conveyor belt is fitted on the outer periphery of the two drive rollers, and mounting plates are provided at both ends of the drive rollers. The mounting plates are rotatably connected to the drive rollers, the top surface of the mounting plates is fixed to the bottom surface of the shelf, and a motor is provided on the side of one of the mounting plates. The output shaft of the motor is fixedly connected to one end of one of the drive rollers.

[0020] By adopting the above technical solution, when a user purchases an item on the placement board, the motor below the corresponding item is started. The output shaft of the motor drives the transmission roller to rotate, and the transmission roller drives the conveyor belt to rotate, thereby causing the conveyor belt to move the item and make the item fall from the placement board onto the buffer board.

[0021] Preferably, a sponge pad is fixed to the top surface of the buffer plate.

[0022] By adopting the above technical solution, a sponge pad is placed on the buffer plate to further protect items that fall onto the buffer plate and reduce the possibility of items being damaged.

[0023] Preferably, a magnet is fixed to the side of the sealing plate near the push plate, and a magnet is fixed to the side of the cabinet, with the magnet attracting the magnet.

[0024] By adopting the above technical solution, a magnet is installed on the sealing plate and a magnet is installed on the cabinet. When the sealing plate is closed, magnets one and two are attracted to each other, thereby reducing the possibility that the sealing plate will open when the spring fails due to prolonged use.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When a user purchases items inside the cabinet, the items fall from the placement board onto the buffer board in the groove. By installing a buffer spring under the buffer board, when the items fall onto the buffer board, the buffer board is cushioned by the elastic force of the buffer spring, thereby reducing the possibility of the items falling from the placement board and getting broken.

[0027] 2. When the item falls onto the buffer plate, start motor two. The output shaft of motor two drives the screw to rotate, the screw drives the synchronous pulley to rotate, the synchronous pulley drives the synchronous belt to rotate, the synchronous belt drives another synchronous pulley to rotate, and the other synchronous pulley drives the other screw to rotate, so that the two screws rotate simultaneously, causing the screw to drive the moving block to move, the moving block drives the push plate to move, and the push plate pushes the item to the opening.

[0028] 3. When the sealing plate is opened, it pulls the rope off the take-up roller. When the item is removed, the sealing plate is released, and the rotating shaft rotates in the opposite direction under the elastic force of the drive component. This causes the rotating shaft to drive the take-up roller to rotate, and the take-up roller winds the rope onto itself. As the take-up roller winds the rope, the rope moves the sealing plate, thereby closing the opening. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses a vending machine for displaying items.

[0039] Reference Figure 1 A vending machine for displaying items includes a cabinet body 1, with a glass door 11 rotatably mounted on the front end of the cabinet body 1. Multiple placement boards 12 for placing items are fixed inside the cabinet body 1, and the multiple placement boards 12 are evenly spaced along the height direction of the cabinet body 1.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The placement plate 12 includes a shelf 13. Multiple through slots 14 are formed on the top surface of the shelf 13. Two drive rollers 15 are installed within each through slot 14. A conveyor belt 16 is fitted around the outer periphery of each drive roller 15. Mounting plates 17 are mounted at both ends of each drive roller 15, and are rotatably connected to the drive rollers 15. The top surface of the mounting plate 17 is fixed to the bottom surface of the shelf 13. A motor 18 is mounted on the side of one of the mounting plates 17, and the output shaft of the motor 18 is fixedly connected to one end of one of the drive rollers 15. A groove 2 is formed on the inner bottom surface of the cabinet 1. An opening 21 is formed on the inner side of the groove 2, and a sealing plate 22 is rotatably mounted within the opening 21.

[0041] When a user needs to purchase an item from the vending machine, the motor 18 below the corresponding item is activated. The output shaft of the motor 18 drives the transmission roller 15 to rotate, which in turn drives the conveyor belt 16 to rotate. The conveyor belt 16 moves the item, causing the item purchased by the user to fall from the placement plate 12 into the groove 2. Then, the user rotates the sealing plate 22 to open the opening 21, making it easier for the user to take out the purchased item.

[0042] Reference Figure 1 and Figure 3 A buffer plate 23 is installed inside the groove 2. A sponge pad 24 is fixed to the top surface of the buffer plate 23, and multiple buffer springs 25 are fixed to the bottom surface of the buffer plate 23. The bottom ends of the buffer springs 25 are fixed to the inner bottom surface of the groove 2. A push plate 3 is installed on the top surface of the buffer plate 23. The bottom surface of the push plate 3 is in contact with the top surface of the buffer plate 23. A slider 32 is fixed to both ends of the push plate 3. A sliding groove 31 is opened on the opposite inner side of the groove 2, and the slider 32 is slidably disposed in the sliding groove 31. An installation groove 34 is opened on the opposite inner side of the groove 2. A screw 35 is rotatably installed between the opposite inner sides of the installation groove 34. A moving block 33 is fixed to both ends of the push plate 3. The moving block 33 is disposed in the installation groove 34. The screw 35 passes through the moving block 33 and is threadedly connected to the moving block 33.

[0043] Reference Figure 3 and Figure 4 The inner side of the groove 2 is provided with a clearance groove 36, which is connected to two mounting grooves 34. Both screws 35 are fitted with and fixed with synchronous pulleys 41, and synchronous belts 42 are wound on the two synchronous pulleys 41. One of the mounting grooves 34 is fixed with a second motor 4, and the output shaft of the second motor 4 is fixedly connected to one end of one of the screws 35.

[0044] Reference Figure 4 , Figure 5 and Figure 6 Pull ropes 54 are fixed to both sides of the sealing plate 22 near the push plate 3. Two parallel side plates 5 are fixed to both sides of the inner side of the cabinet 1. A rotating shaft 51 is rotatably mounted between the two side plates 5, and a winding roller 52 is sleeved and fixed on the rotating shaft 51. Through holes 55 are opened on both sides of the inner side of the cabinet 1. The end of the pull rope 54 away from the sealing plate 22 passes through the through hole 55 and is fixed to the outer circumference of the winding roller 52. A coil spring 53 is sleeved on the rotating shaft 51. One end of the coil spring 53 is fixedly connected to the inner and outer circumferences of the rotating shaft 51, and the other end of the coil spring 53 is fixedly connected to the inner side of the cabinet 1. Two magnets 56 are fixed to the side of the sealing plate 22 near the push plate 3. Two magnets 57 are fixed to the side of the cabinet 1. Magnets 56 and magnets 57 are attracted to each other.

[0045] Reference Figure 4 , Figure 5 and Figure 7A power supply 6 is fixed to the side of cabinet 1 away from the sealing plate 22. A slot 61 is formed on the side of cabinet 1 away from the power supply 6. A connecting groove 62 is formed on the inner side of the slot 61. A fixed contact 63 is fixed to the inner side of the connecting groove 62 away from the power supply 6. An actuating block 64 is slidably disposed in the connecting groove 62. A moving contact 65 is fixed to the side of the actuating block 64 near the fixed contact 63. The sides of the moving contact 65 and the fixed contact 63 that are close to each other can fit together. An actuating post 67 is fixed to the side of the actuating block 64 near the fixed contact 63. One end of the actuating post 67 away from the actuating block 64 protrudes from the slot 61. The terminal of the moving contact 65 is electrically connected to one terminal of the power supply 6. The other terminal of the power supply 6 is electrically connected to one terminal of the motor 4. The other terminal of the motor 4 is electrically connected to the terminal of the fixed contact 63. A spring 66 is fixed to the side of the actuating block 64 near the power supply 6, and the end of the spring 66 away from the actuating block 64 is fixedly connected to the inner wall of the connecting groove 62.

[0046] When the sealing plate 22 is opened, the actuating block 64 moves towards the fixed contact 63 under the elastic force of the spring 66, causing the actuating block 64 to drive the moving contact 65 towards the fixed contact 63, so that the sides of the fixed contact 63 and the moving contact 65 are in contact, thereby energizing the motor 4, causing the output shaft of the motor 4 to drive the screw 35 to rotate, the screw 35 to drive the synchronous pulley 41 to rotate, the synchronous pulley 41 to drive the synchronous belt 42 to rotate, the synchronous belt 42 to drive the other synchronous pulley 41 to rotate, thereby causing the two screws 35 to rotate simultaneously, causing the screws 35 to drive the moving block 33 to move, the moving block 33 to drive the push plate 3 to move, and then the push plate 3 to push the item to the opening 21.

[0047] The implementation principle of a vending machine for displaying items in this application embodiment is as follows: When a user purchases an item from the vending machine, the item falls onto the buffer plate 23. By setting a buffer spring 25 below the buffer plate 23, when the item falls onto the buffer plate 23, the elastic force of the buffer spring 25 buffers the impact force of the item falling onto the buffer plate 23, thereby reducing the possibility of the item falling from the placement plate 12 and being damaged.

[0048] When it is necessary to remove an item that has fallen onto the buffer plate 23, the sealing plate 22 is opened. Under the elastic force of the spring 66, the actuating block 64 moves towards the fixed contact 63, causing the moving contact 65 to move towards the fixed contact 63. This causes the end faces of the fixed contact 63 and the moving contact 65 to come into contact, thereby energizing the motor 18. The output shaft of the motor 18 drives the screw 35 to rotate, which in turn drives the synchronous pulley 41 to rotate. The synchronous pulley 41 drives the synchronous belt 42 to rotate, which in turn drives another synchronous pulley 41 to rotate. This causes both screws 35 to rotate simultaneously. The screws 35 drive the moving block 33 to move towards the sealing plate 22, which in turn drives the push plate 3 to move towards the sealing plate 22. This push plate 3 then pushes the item to the opening 21, making it easier for the user to remove the item.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
