Description

Technical Field

[0001] The utility model relates to the technical field of automatic vending, and specifically, to a vending machine. Background Art

[0002] A vending machine is a commonly used device for commercial automation. It is not restricted by time and location, can save manpower, and facilitate transactions. It is a brand-new form of commercial retail. With the improvement of people's living standards, the application fields of vending machines are becoming more and more extensive. In order to adapt to the fast-paced lifestyle, vending machines can also sell lunch boxes.

[0003] The patent application with the patent number CN107067551 B discloses a lunch box automatic vending cabinet. During the working process of this lunch box automatic vending cabinet, the lunch boxes are placed on an inclined shelf. In the initial state, the rotating stopper passes through the rotating stopper outlet and catches the bottom of the lunch box so that the lunch box will not slide down. When a user orders a specified lunch box on the control panel and needs to pick it up, the rotating motor is started. The operation of the rotating motor drives the rotation of the longitudinal synchronous belt, so that the moving tray moves synchronously along the slide rail. After the moving tray is lifted to the specified position, the electric push rod pushes the push plate upward. The push plate enters from the push plate socket and presses the rotating stopper downward and compresses the torsion spring. During this downward pressing process, the lunch box slides upward. When the push plate completely presses the rotating stopper under the lunch box, the lunch box begins to slide down onto the moving tray under the action of its own weight. After the photoelectric sensor senses that the lunch box slides into the moving tray, the electric push rod contracts to drive the push plate to complete the reset. After the pressure is removed, the rotating stopper rotates upward under the resilience of the torsion spring until it catches the next lunch box. Finally, the moving tray delivers the lunch box to the pick-up port to complete the automatic vending.

[0004] However, there are at least the following problems in the related art: In the prior art, during the meal delivery process of the lunch box, usually a pushing device is used to convey the lunch box from the tray to the pick-up platform of the vending machine. However, there is a certain gap between the tray and the pick-up platform, resulting in the lunch box being prone to shaking or tilting during the meal delivery process, thus causing the soup in the lunch box to spill out of the lunch box and reducing the user experience. Summary of the Utility Model

Detailed implementation manner

[0037] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is given with reference to the accompanying drawings.

[0038] An embodiment of the present utility model provides a vending machine. The vending machine is used to accommodate the meal box 100. The vending machine includes a meal outlet for outputting the meal box 100, and a meal delivery device 200 disposed opposite to the meal outlet. The meal delivery device 200 includes a base 210. The base 210 is provided with a tray 230, a transmission structure 240, a guide structure 220, and a driving component 250. Among them, the guide structure 220 is disposed on the installation side of the base 210. The tray 230 is slidably connected to the side of the guide structure 220 away from the base 210, and the tray 230 is provided with a placement position 231 for placing the meal box 100. The transmission structure 240 is disposed on the installation side of the base 210, and during the transmission process, the transmission structure 240 drives the tray 230 to move together. The driving component 250 is drivingly connected to the transmission structure 240 so that the transmission structure 240 drives the tray 230 to reciprocate along the guide structure 220. When the tray 230 moves to the first relative position of the guide structure 220 close to the meal outlet, at least a part of the tray 230 extends out of the meal outlet to send the meal box 100 placed in the placement position 231 out of the vending machine, facilitating the user to take away the meal box 100 from the placement position 231. Thereby, the stability of the meal box 100 during the meal delivery process is increased, and the situation that the meal box 100 is prone to shaking or tilting during the meal delivery process, causing the soup in the meal box 100 to spill out of the meal box 100, is avoided, thereby improving the user experience.

[0039] Specifically, by setting the transmission structure 240 to cooperate with the driving component 250, the tray 230 is moved to a position where at least a part of it extends out of the food outlet, so that the lunch box 100 placed at the placement position 231 can be stably and accurately removed from the vending machine. At the same time, by setting the guiding structure 220, the moving direction of the tray 230 is restricted, increasing the stability of the lunch box 100 during the food outlet process. And when at least a part of the tray 230 extends out of the food outlet, through the connection between the guiding structure 220 and the tray 230, the stability of the tray 230 is increased, thereby further increasing the stability of the lunch box 100 during the food outlet process, and further improving the user experience.

[0040] Further, continue to refer to Figure 5 , the guiding structure 220 includes a slider 221 and a slide rail 222. The slider 221 is arranged at the bottom of the tray 230, the slide rail 222 is arranged on the base 210, and the slide rail 222 is arranged opposite to the food outlet; wherein, the slider 221 is slidably matched with the slide rail 222 to enable the guiding structure 220 to be slidably connected with the tray 230. Further increasing the stability of the lunch box 100 during the food outlet process.

[0041] Specifically, in this solution, the guiding structure 220 reduces the bumps and vibrations of the lunch box 100 during the food outlet process by setting the slider 221 to cooperate with the slide rail 222, avoiding the situation where the food in the lunch box 100 spills out during the food outlet process of the lunch box 100, thereby ensuring the smoothness of the tray 230 during the movement. And by the slider 221 moving along the slide rail 222, it is ensured that the transmission structure 240 will not deviate from the moving track when driving the tray 230 to move, thereby further increasing the stability of the lunch box 100 during the food outlet process.

[0042] Further, when the tray 230 is in the first relative position, the driving component 250 rotates in the first direction to move the tray 230 to the second relative position away from the food outlet of the guiding structure 220.

[0043] Furthermore, when the tray 230 is in the second relative position, the driving component 250 rotates in the second direction opposite to the first direction to move the tray 230 to the first relative position, and at least a part of the tray 230 extends out of the food outlet.

[0044] Specifically, by driving the driving component 250 to rotate along the first direction or the second direction, the tray 230 can automatically move between the first relative position and the second relative position, so that the meal delivery device 200 realizes the requirement of automatic movement, thereby reducing the need for manual operation and improving the meal delivery efficiency of the vending machine; at the same time, the driving component 250 can also accurately control the moving distance of the tray 230 to ensure that the tray 230 can accurately reach the first relative position or the second relative position during the meal delivery process. Further, the automatic movement reduces the risk of collision or slipping during the manual operation process and improves the safety during the meal delivery process of the food container 100.

[0045] Further, continue to refer to Figures 1 to 4 , the placement position 231 protrudes relative to the tray 230 to form a boss. The meal delivery device 200 further includes a pressure sensor 232. The pressure sensor 232 is disposed on the boss, and the pressure sensor 232 contacts the food container 100 placed on the placement position 231. A support member 233 is disposed at the bottom of the pressure sensor 232 to fixedly connect the pressure sensor 232 to the tray 230; wherein, the pressure sensor 232 is communicatively connected to the driving component 250, and when the pressure sensor 232 detects that the food container 100 is placed on the placement position 231, the driving component 250 drives the transmission structure 240 to rotate so that the tray 230 moves to the first relative position; when the pressure sensor 232 detects that the food container 100 leaves the placement position 231, the driving component 250 drives the transmission structure 240 to rotate so that the tray 230 moves to the second relative position.

[0046] Specifically, the movement of the tray 230 is realized by placing the food container 100 on the placement position 231 or removing it from the placement position 231 to achieve automatic control. During the meal delivery process, the staff does not need to manually operate the tray 230, thus saving labor costs; and the automatic control reduces the possibility of human operation errors, thereby avoiding the situation of the food in the food container 100 spilling out, and further improving the stability of the food container 100 during the meal delivery process and reducing food waste.

[0047] Further, continue to refer to Figure 5 , the transmission structure 240 includes a conveyor belt 241 and a rotating component. The conveyor belt 241 is disposed at the bottom of the tray 230, and the conveyor belt 241 is fixedly connected to the tray 230 through a fixing block 244. The rotating component is disposed on the base 210, and the rotating component is rotationally matched with the conveyor belt 241; wherein, the driving component 250 drives the rotating component to rotate to drive the tray 230 to reciprocate along the guiding structure 220 through the transmission structure 240. Further improves the stability of the food container 100 during the meal delivery process.

[0048] Even further, continue to refer to Figure 5, the rotating assembly includes an active runner 242 and a driven runner 243 which are oppositely arranged; the active runner 242 is arranged at a position of the base 210 close to the food outlet, the driven runner 243 is arranged at a position of the base 210 away from the food outlet, and the conveyor belt 241 is rotationally engaged with the active runner 242 and the driven runner 243; wherein, when the driving component 250 drives the active runner 242 to rotate, the active runner 242 drives the driven runner 243 to rotate.

[0049] Further, continue to refer to Figures 1 to 8 , the food delivery device 200 includes a switch member which is arranged on the base 210 and is oppositely arranged with the food outlet; a protruding member 234 which is arranged on one side of the tray 230 close to the switch member and is engaged with the switch member; wherein, the switch member is communicatively connected with the driving component 250 to control the opening and closing of the driving component 250. Among them, by arranging the switch member, the position of the protruding member 234 can be accurately detected, so as to accurately control the opening and closing of the driving component 250, ensuring that the tray 230 can stop at a predetermined position and improving the accuracy of the position during the conveying process of the food container 100.

[0050] Furthermore, continue to refer to Figures 1 to 8 , the switch member includes a first stop member 260 and a second stop member 270 which are oppositely arranged, and the first stop member 260 is arranged at one end of the switch member away from the food outlet, and the second stop member 270 is arranged at one end of the switch member close to the food outlet; wherein, when the protruding member 234 contacts the first stop member 260 or the protruding member 234 contacts the second stop member 270, the driving component 250 stops driving to limit the displacement of the transmission structure 240 driving the tray 230 to move.

[0051] Specifically, as Figure 8 shown, the first stop member 260 is composed of a stop piece 261 and an elastic member 262 which cooperate with each other. Among them, when the protruding member 234 contacts the first stop member 260, the protruding member 234 abuts against the stop piece 261, so that the stop piece 261 applies pressure to the elastic member 262, thereby causing the driving component 250 to stop driving. Further, the second stop member 270 has the same structure as the first stop member 260, and the difference lies in the set position.

[0052] The tray 230 is provided with a limiting structure for restricting the movement of the food container 100 to restrict the movement of the food container 100 when the transmission structure 240 drives the tray 230 to move.

[0053] Specifically, the limiting structure is a groove-like structure, a boss is arranged in the middle of the limiting structure, and the edge of the limiting structure is higher than the contact surface between the food container 100 and the boss to restrict the movement of the food container 100 during the movement of the tray 230.

[0054] In a specific embodiment, after the pressure sensor 232 detects that the meal box 100 is placed at the placement position 231, the controller of the vending machine (not shown in the figure) controls the driving component 250 to rotate in the second direction, so that the conveyor belt 241 drives the tray 230 to move towards the meal outlet of the vending machine during the transmission process until the raised part 234 contacts the second stop member 270, and then the driving component 250 stops driving. At this time, the tray 230 is located at the first relative position, and at least a part of the tray 230 extends out of the meal outlet for the user to pick up the meal box 100. After the pressure sensor 232 detects that the user has taken away the meal box 100, the driving component 250 moves in the second direction to move the tray 230 to the second relative position. When the raised part 234 contacts the first stop member 260, the driving component 250 stops driving and waits for the next transmission instruction.

[0055] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
