Description

Technical Field

[0001] This utility model relates to the field of vending machine technology, specifically a balloon vending machine. Background Technology

[0002] Balloons are a favorite toy for children, but in places frequented by children, such as playgrounds, balloons are typically inflated and provided by vendors on-site, resulting in high operating costs. To address this issue, automated balloon vending machines have emerged. These machines store a large variety of uninflated balloons, and consumers can browse and select their desired balloons using a selection device (such as a touchscreen). After selection, the machine automatically handles the selection, dispensing, inflating, and dispensing of the balloons. However, existing balloon vending machines typically suffer from the following technical problems: the balloon-grabbing system is overly complex, difficult to manufacture and assemble, prone to damage affecting the overall lifespan of the machine, and has low cost-effectiveness. Utility Model Content

[0003] In order to overcome the defects in the existing technology, the objective of this utility model is to provide a balloon vending machine with a simple and ingenious structural design, easy manufacturing and assembly, stable operation, long service life, and high cost performance.

[0004] This utility model achieves its objective through the following technical solutions:

[0005] A balloon vending machine includes a cabinet, a selection device, and a controller. The cabinet contains a balloon storage compartment and a balloon dispensing and inflation device. The controller connects the selection device and the balloon dispensing and inflation device. The balloon storage compartment includes at least one balloon storage compartment arranged side-by-side, used for stacking and storing uninflated balloons with rigid balloon holders. Each storage compartment has a vertical groove on its side wall for the balloon holder to pass through and for guiding and limiting the balloon holder. The groove extends through the top of the storage compartment. The balloon dispensing and inflation device includes a balloon dispensing frame and a mechanism capable of driving the dispensing frame along any... The ball picker is equipped with a first drive mechanism for the up-and-down movement of the slide, an inflation pipe and an air source. The ball picker is provided with a support part for supporting the ball holder, a second drive mechanism for driving the support part to extend and retract, and a first sensor. The support part is provided with an inflation port, which is connected to the air source through an inflation pipe. When the ball picker moves downward to the point where the first sensor is triggered by the uppermost ball holder in the slide, the support part is aligned with the ball holder so that the support part can support the ball holder when it extends and the inflation port is connected to the air inlet on the ball holder.

[0006] As a preferred technical solution, the ball-retrieving frame is further provided with a downwardly protruding positioning part. The lower surface of the positioning part is provided with a positioning groove that adapts to the upper surface of the ball holder. When the ball-retrieving frame moves downward along any slide direction until the sensor is triggered by the uppermost ball holder in the slide, the lower surface of the positioning part can abut against the upper surface of the ball holder.

[0007] As a preferred technical solution, a soft rubber pad is provided around the inflation port so that when the inflation port comes into contact with the air inlet on the ball support, the soft rubber pad can be squeezed by the ball support to achieve a sealed connection between the two.

[0008] As a preferred technical solution, the cabinet is also equipped with a stick delivery device, which includes a stick storage compartment, a stick delivery shaft, and a knob. The stick storage compartment is used to store sticks that can be adapted to connect to the ball holder. The bottom of the stick storage compartment is provided with a stick drop opening. The stick delivery shaft is rotatably set at the stick drop opening and can block the stick drop opening to prevent the sticks in the stick storage compartment from falling out. The stick delivery shaft is provided with a groove for a single stick to be inserted. When the stick delivery shaft rotates to the point where the groove is directly opposite the stick drop opening, a stick will fall into the groove. When the stick delivery shaft continues to rotate to the point where the groove faces downward, the stick will be poured out. The knob is exposed in the cabinet. The knob is connected to the stick delivery shaft and can drive the stick delivery shaft to rotate.

[0009] As a preferred technical solution, the stick-out device further includes a locking mechanism and a sensing mechanism. The knob is directly or via a connecting rod connected to the stick-out shaft. The locking mechanism includes a locking plate disposed on the knob or connecting rod, and a locking pin and a locking pin drive mechanism that cooperate with the locking plate. When the locking pin extends, it is located on the rotation path of the locking plate, thereby restricting the rotation of the knob. When the locking pin retracts, it can release the restriction. The sensing mechanism includes a second sensor disposed below the stick-out shaft. The controller is connected to the second sensor and the locking pin drive mechanism. The second sensor can be triggered when the stick is poured out of the groove of the stick-out shaft. And / or, the sensing mechanism includes an eccentric shaft disposed at the end of the stick-out shaft and a third sensor that cooperates with the eccentric shaft. The controller is connected to the third sensor and the locking pin drive mechanism. The third sensor can be triggered once every rotation of the stick-out shaft. The controller is connected to the locking pin drive mechanism, as well as the second sensor and / or the third sensor, and can control the locking pin drive mechanism to drive the locking pin to extend when the second sensor and / or the third sensor is triggered.

[0010] As a preferred technical solution, the first driving mechanism includes a Z-axis moving mechanism that can move up and down along the height direction of the cabinet, and an X-axis moving mechanism that is disposed on the Z-axis moving mechanism and can move laterally along the left and right directions of the cabinet. The ball picker is mounted on the X-axis moving mechanism, so that it can move in the XZ plane under the drive of the first driving mechanism.

[0011] As a preferred technical solution, an anti-theft door and an anti-theft door drive mechanism are provided between the retrieval port and the balloon storage compartment. The controller is connected to the anti-theft door drive mechanism and can control the operation of the anti-theft door drive mechanism according to the built-in program, the input signal of the optional device, or the additional sensor used to detect whether the balloon has been taken out.

[0012] As a preferred technical solution, the internal space of the cabinet is divided into a front space and a rear space, with a front door and a rear door respectively. The ball storage compartment, ball retrieval rack, and first drive mechanism are located in the rear space. An inflation area is reserved above the ball storage compartment. The front space is divided into an upper space, a middle space, and a lower space by a first partition and a second partition that are spaced vertically. The upper space is used to place the air source, the middle space is used to place the inflated balloons ready to be retrieved, and the retrieval port is located at the front door and faces the middle space.

[0013] Compared with the prior art, the balloon vending machine provided by this utility model has the following advantages: During operation, it is only necessary to drive the balloon-retrieving frame to move downward along the slide of the selected balloon type until the first sensor is triggered by the uppermost balloon holder in the slide. Then, the downward movement stops, and the supporting part is driven to extend forward. With the limiting of the rigid balloon holder of the slide, the supporting part can hold the balloon holder and make the inflation port connected to the air inlet on the balloon holder. Then, the balloon-retrieving frame is driven to move upward to lift the balloon up to the top of the slide. Then, the balloon is inflated through the inflation port, thus completing a series of actions such as balloon selection, grabbing, and inflation. The balloon-retrieving and inflation device has a simple and ingenious structural design, is easy to manufacture and assemble, and works stably.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. It should be noted that when an element is referred to as "connecting" or "communicating" with another element, it can be a direct connection to the other element or a connection through other intermediary elements. Unless otherwise specified, it can be a non-detachable connection or a detachable connection. Similar expressions are for illustrative purposes only and are not intended to limit the present utility model.

[0024] like Figure 1-7 As shown, this embodiment provides a balloon vending machine, including a cabinet 1, a purchasing device 2, and a controller. The cabinet 1 is equipped with a balloon storage compartment 3, a balloon dispensing and inflation device, and a balloon dispensing device 4. The controller is connected to the purchasing device 2 and the balloon dispensing and inflation device, and can control the balloon dispensing and inflation device to operate automatically according to the purchasing information of the purchasing device 2.

[0025] The balloon storage compartment 3 includes several balloon storage cells 31 arranged side by side. The balloon storage cells 31 are used to stack and store uninflated balloons 100 with rigid balloon holders 101. The side wall of each balloon storage cell 31 is provided with a vertical groove 311 for the balloon holder 101 to pass through and for guiding and limiting the balloon holder 101. The groove 311 extends through the top of the balloon storage cell 31. The balloon retrieval and inflation device includes a balloon retrieval frame 5, a first drive mechanism 6 capable of driving the balloon retrieval frame 5 to move up and down along any of the grooves 311, and an inflation pipe and an air source. The balloon retrieval frame 5 is provided with a support part 5 for supporting the balloon holder 101. 1. A second drive mechanism 52 for driving the support part 51 to perform telescopic movement, and a first sensor 53. The support part 51 is provided with an air inlet 54, which is connected to an air source through an air inlet pipe. When the ball picker 5 moves downward until the first sensor 53 is triggered by the uppermost ball holder 101 in the slide groove 311, the support part 51 and the ball holder 101 are aligned so that the support part 51 can support the ball holder 101 when it extends and the air inlet 54 is connected to the air inlet on the ball holder 101. The stick delivery device 4 is used to provide a stick 200 that can be adapted to connect to the ball holder 101. In this application, the applicable ball support 101 generally includes a base 1011, a neck 1012 located at the front end of the base 1011, a baffle 1013 located in front of the neck 1012, and an air inlet pipe 1014 located in front of the baffle 1013. The air inlet pipe 1014 is provided with the air inlet hole and the air inlet hole extends through the base 1011. The width of the neck 1012 is smaller than that of the baffle 1013 and the base 1011. During use, the neck 1012 is embedded in the slide groove 311 and therefore cannot move back and forth. Preferably, the neck 1012 is a square structure adapted to the width of the slide groove 311. This ensures that the ball support will not deflect when it moves upward in the slide groove 311, making it more stable.

[0026] This embodiment provides a balloon vending machine where each storage compartment 31 typically holds different types of uninflated balloons 100. After a consumer selects the type of balloon 100 using the selection device 2 and inputs purchase information (such as purchase and payment details), the controller controls the first drive mechanism 6 to drive the balloon-retrieving rack 5 to move downwards along the chute 311 containing the selected balloon type until the first sensor 53 is triggered by the uppermost balloon holder 101 in the chute 311. Then, the downward movement stops, and the second drive mechanism 52 drives the supporting part 51 to extend forward, cooperating with the chute 311 to press against the balloon 100. The ball holder 101 is positioned so that the supporting part 51 can hold the ball holder 101 and the inflation port 54 can be connected to the air inlet on the ball holder 101. Then, the ball picker 5 is driven to move upward, which can lift the balloon 100 to the top of the slide 311. Then, the air source is controlled to inflate the balloon 100 through the inflation port 54. Since the balloon 100 is generally equipped with self-adhesive at the mouth, the mouth will automatically close and seal after the balloon is inflated. This completes a series of actions such as selecting, picking up, and inflating the balloon 100. The ball picking and inflation device has a simple and ingenious structural design, is easy to manufacture and assemble, and works stably.

[0027] As one preferred embodiment, the ball-retrieving frame 5 is also provided with a downwardly protruding positioning part 55. The lower surface of the positioning part 55 is provided with a positioning groove that adapts to the upper surface of the ball holder 101. When the ball-retrieving frame 5 moves downward along any of the slide grooves 311 until the sensor is triggered by the uppermost ball holder 101 in the slide groove 311, the lower surface of the positioning part 55 can abut against the upper surface of the ball holder 101. In this embodiment, by setting the positioning part 55, the ball holder 101 can be positioned from the top, thereby making the support part 51 more stable when holding the balloon 100.

[0028] As one preferred embodiment, the inflation port 54 is provided with a soft rubber pad 56 around its periphery, so that when the inflation port 54 comes into contact with the air inlet on the ball support 101, the soft rubber pad 56 can be squeezed by the ball support 101 to achieve a sealed connection between the two.

[0029] As one preferred embodiment, the stick-dispensing device 4 includes a stick storage compartment 41, a stick-dispensing shaft 42, and a knob 43. The stick storage compartment 41 is used to store sticks that can be adapted to connect to the ball holder. The bottom of the stick storage compartment 41 is provided with a stick-dropping opening. The stick-dispensing shaft 42 is rotatably mounted at the stick-dropping opening and can block the stick-dropping opening to prevent the sticks 200 in the stick storage compartment 41 from falling out. The stick-dispensing shaft 42 is provided with a groove 421 for a single stick 200 to be inserted. When the stick-dispensing shaft 42 is rotated until the groove 421 is directly opposite the stick-dropping opening, a stick 200 will fall into the groove 421. 21. When the stick shaft 42 continues to rotate until the groove faces downward, the stick 200 will be poured out, and the knob 43 will be exposed in the cabinet 1. The knob 43 is connected to the stick shaft 42, which can drive the stick shaft 42 to rotate. In use, the consumer can manually rotate the knob 43 to take out the stick 200, and then insert the stick 200 into the ball holder 101 of the balloon 100 for easy holding and carrying. Manually rotating the knob 43 to take out the stick 200 makes the game more interesting and can increase the consumer's sense of participation and enhance the user experience.

[0030] As one preferred embodiment, the stick-out device 4 further includes a locking mechanism 44 and a sensing mechanism. The knob 43 is directly or via a connecting rod 422 connected to the stick-out shaft 42. The locking mechanism 44 includes a locking plate 441 disposed on the knob 43 or the connecting rod 422, a locking pin 442 cooperating with the locking plate 441, and a locking pin drive mechanism 443. When the locking pin 442 extends, it is located on the rotation path of the locking plate 441, thereby restricting the rotation of the knob 43. When the locking pin 442 retracts, it can release the restriction. The sensing mechanism includes a second sensor 451 disposed below the stick-out shaft 42. The controller is connected to the second sensor 451 and the locking pin drive mechanism 443. When the stick 200 is poured out of the groove of the stick-out shaft 42, the second sensor 451 can be triggered.

[0031] As one preferred embodiment, the sensing mechanism includes an eccentric shaft 452 disposed at the end of the stick-out shaft 42 and a third sensor 453 that cooperates with the eccentric shaft 452. The controller connects the third sensor 453 and the locking pin drive mechanism 453, and the third sensor 453 is triggered once every time the stick-out shaft 42 rotates.

[0032] The controller connects to the locking pin drive mechanism 453, the second sensor 451, and / or the third sensor 453, and can control the locking pin drive mechanism 453 to extend the locking pin 452 when the second sensor 451 and / or the third sensor 453 are triggered. By setting the locking mechanism 44 and the sensing mechanism, each time a consumer buys a balloon 100, only one stick 200 can be taken out by turning the knob 43, which can prevent individual consumers from maliciously taking out multiple sticks 200 and causing losses. Among them, the locking pin drive mechanism 453 is preferably an electromagnet drive mechanism, but a motor or pneumatic drive mechanism can also be selected.

[0033] As one preferred embodiment, the first drive mechanism 6 includes a Z-axis moving mechanism 61 that can move up and down along the height direction of the cabinet 1, and an X-axis moving mechanism 62 that is disposed on the Z-axis moving mechanism 61 and can move laterally along the left and right directions of the cabinet 1. The ball picker 5 is mounted on the X-axis moving mechanism 62, so that it can move in the XZ plane under the drive of the first drive mechanism 6. The first drive mechanism 6 provided by this embodiment can not only ensure that the ball picker 5 is driven to any ball storage compartment 31 and moves up and down along the corresponding slide 311, but also has a compact structure, which can reduce the space occupied by the cabinet 1, so as to save space to increase the volume of the ball storage compartment 3.

[0034] As one preferred embodiment, an anti-theft door 7 and an anti-theft door drive mechanism 71 are provided between the retrieval port and the balloon storage compartment 3. The controller is connected to the anti-theft door drive mechanism 71 and can control the operation of the anti-theft door drive mechanism 71 according to the built-in program, the input signal of the optional device 2, or a separately provided sensor for detecting whether the balloon 100 has been taken out. This embodiment, by setting the anti-theft door 7 and the anti-theft door drive mechanism 71, can prevent criminals or naughty children from stealing the balloons 100 in the balloon storage compartment 3.

[0035] As one preferred embodiment, the air source includes an air pump 81, which enables the balloons 100 for sale to be inflated with air.

[0036] As one preferred embodiment, the gas source includes an air source and a helium tank 82. The air source is an air pump 81. The outlets of the helium tank 82 and the air pump 81 are connected to the inflation pipe via a solenoid valve (not shown in the attached diagram). The solenoid valve is connected to the controller, which can control the solenoid valve according to the input signal from the optional device 2, thereby controlling the inflation pipe to connect to the helium tank 82 or the air pump 81, i.e., controlling the gas supply from the helium tank or the air source. This solution can provide both air-filled balloons (non-floating balloons) and helium-filled balloons (floating balloons) according to the consumer's choice. Both share the balloon storage compartment and the balloon filling device, resulting in a compact structure and high cost-effectiveness.

[0037] As one preferred embodiment, the internal space of the cabinet 1 is divided into a front space and a rear space. The anti-theft door 7 is used to close the connection between the front space and the rear space. The front space and the rear space are respectively provided with a front cabinet door and a rear cabinet door. The ball storage compartment 3, the ball retrieval rack 5 and the first drive mechanism 6 are located in the rear space. An inflation area is reserved above the ball storage compartment 3. The front space is divided into an upper space, a middle space and a lower space by a first partition 12 and a second partition 13 arranged vertically. The upper space is used to place the air source, and the middle space is used to place the inflated balloons 100 that are ready to be taken away. The retrieval port 11 is located at the front cabinet door and faces the middle space. This embodiment has a compact structure design. The second partition 13 at the bottom of the middle space supports the inflated balloons 100 and faces the retrieval port 11, making it convenient for consumers to retrieve the goods without bending over. At the same time, the lower space can be used as storage space or to place the machine's motor, circuit board and other equipment.

[0038] The above-mentioned balloon vending machine operates by including the following steps:

[0039] S1. The purchasing device 2 acquires purchasing information and sends the purchasing information to the controller. After receiving the purchasing information, the controller controls the first driving mechanism 6 to drive the ball picker 5 to move to the upper part of the slide 311 of the corresponding ball storage compartment 31, and then move down along the slide 311 until the first sensor 53 touches the uppermost air inlet 54 of the slide 311 and is triggered. The first sensor 53 sends the trigger signal to the controller, and the first driving mechanism 6 stops moving.

[0040] S2. The second drive mechanism 52 drives the support part 51 to extend a set distance so that the support part 51 can support the ball support 101 and the inflation port 54 is connected to the air inlet on the ball support 101.

[0041] S3. The first driving mechanism 6 drives the ball picker 5 to move upward along the slide 311 to the upper end of the slide 311, and then the air source blows air into the balloon 100 through the air inlet 54, thereby inflating the balloon 100.

[0042] S4. The first drive mechanism 6 drives the ball picker 5 to continue moving upward a set distance until it disengages from the slide 311;

[0043] S5. The air source then inflates the air inlet 54, causing the air inlet 54 to detach from the ball picker 5, thus completing the shipment.

[0044] In this embodiment, through the above steps, the balloon vending machine can automatically complete the selection, retrieval, inflation, and dispensing of balloons 100, so that users can obtain inflated balloons 100. Moreover, based on the balloon retrieval and inflation device in Embodiment 1, the working process and control program of the balloon vending machine are simpler and more stable. Furthermore, the above steps S4 and S5 can use the air pressure of the air source to push out the inflated balloons 100, completing the automatic dispensing. This eliminates the need for consumers to manually retrieve the inflated balloons 100, thus improving the user experience. It also prevents accidents such as balloons 100 bursting during manual removal. In addition, it facilitates the controller to set up internal programs such as automatic reset of the balloon retrieval and inflation device and automatic closing of the security door 7, without needing to detect and determine whether the consumer has removed the balloons 100 before controlling the automatic reset of the balloon retrieval and inflation device and the automatic closing of the security door 7.

[0045] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
