[0037] In the technical solution, the commodity normal taking outlet 11 and the abnormal commodity storage area 12 are simultaneously constructed on the cabinet shell 1, and the commodity conveying assembly can convey the commodity 100 carried thereon to the commodity normal taking outlet 11 or the abnormal commodity storage area 12 according to the actual situation, thereby effectively avoiding the phenomenon that the commodity selling cabinet in the prior art cannot normally distribute the commodities corresponding to the order after restarting and powering on due to abnormal conditions, leading to distribution errors and hindering the subsequent purchase process of the product, improving the user experience and the reliability of the product.
[0038] In a feasible embodiment, a corresponding display screen 13 can also be arranged on the cabinet shell 1 of the commodity selling cabinet, which is specifically a touch screen.When the commodity selling cabinet restarts and powers on due to abnormal conditions, the maintenance personnel can issue corresponding control instructions through the touch screen to control the commodity conveying assembly to move to the abnormal commodity storage area 12 and send the commodity 100 carried thereon into the abnormal commodity storage area 12, that is, to empty the commodity conveying assembly to continue the subsequent order processing process.Of course, the movement of the aforementioned commodity conveying assembly can also be realized in some special cases by manual control, and as a more preferred implementation manner, the movement of the aforementioned commodity conveying assembly can be controlled by the automatic control of the related control components in the commodity selling cabinet.
[0039] In some embodiments, the goods conveying assembly includes a lifting platform 221 and a traversing platform 222, wherein the traversing platform 222 is slidably connected to the top surface of the lifting platform 221 so as to be driven to reciprocate horizontally, the lifting platform 221 can be controlled to lift, and the goods 100 can be carried on the top surface of the traversing platform 222. Specifically, the aforementioned traversing platform 222 and lifting platform 221 can employ a lead screw module as used in the prior art.
[0040] In this technical solution, a commodity conveying assembly is composed of a lifting platform 221 and a transverse platform 222. The combined lifting and transverse movement method makes the movement more stable and ensures the smooth delivery of commodities.
[0041] In some implementation methods, see details. Figure 2 As shown, the transverse platform 222 includes a platform frame 2221 and multiple parallel and spaced rollers 2222 connected within the platform frame 2221. The goods channel 21 has a conveyor belt 211, and the conveying direction of the conveyor belt 211 is perpendicular to the axial direction of the rollers 2222 in the horizontal plane.
[0042] In this technical solution, the goods 100 are conveyed from the goods channel 21 to the bearing surface formed by each roller 2222 by the conveyor belt 211, which makes the overall structural design of the goods vending cabinet more reasonable.
[0043] In some embodiments, the transverse platform 222 further includes a platform pusher plate 2223 for pushing the product 100 on the roller 2222 along the axial direction of the roller 2222; and / or, the product channel 21 further includes a channel pusher plate 212 for pushing the product 100 on the conveyor belt 211 along the conveying direction of the conveyor belt 211. The aforementioned platform pusher plate 2223 and channel pusher plate 212 can be telescopically extended using electric actuators.
[0044] In this technical solution, by setting a platform pusher plate 2223 on the transverse platform 222, the goods 100 placed on the roller 2222 can be smoothly pushed to the aforementioned normal goods outlet 11 or abnormal goods storage area 12. By setting a channel pusher plate 212 on the channel pusher plate 212, the goods 100 in the goods channel 21 can be smoothly pushed out synchronously with the conveyor belt 211. Especially for goods 100 with a large height, the force on the goods 100 in the height direction can be uniformly applied, and the goods 100 can be sent out at a high pushing speed.
[0045] In some embodiments, the platform frame 2221 has a first area (not labeled in the figure) close to the commodity shelves 21 and a second area (not labeled in the figure) away from the commodity shelves 21, the rollers 2222 in the first area are active rotating rollers, and the rollers 2222 in the second area are driven rotating rollers. The aforementioned active rotating rollers are rollers 2222 that are provided with corresponding rotating power components (such as rotary motors) to enable self-driven rotation, and the aforementioned driven rotating rollers are rollers 2222 that are not provided with driving components and are rotatably connected to corresponding mounting carriers through rotating shafts, and the rotating power comes from the static friction force with a certain moving speed.
[0046] In the technical solution, the rollers 2222 in the first area close to the commodity shelves 21 are active rotating rollers, which can utilize the self-driven ability of the rollers 2222 to more efficiently and stably transfer the commodities sent out by the commodity shelves 21, and the rollers 2222 in the second area away from the commodity shelves 21 are driven rotating rollers, which reduces the overall manufacturing cost of the equipment.
[0047] Specifically referring to Figure 3 As shown in the figure, in some embodiments, the projection of the platform frame 2221 on the horizontal plane is a rectangle, and the platform frame 2221 is provided with a first detection component (not labeled in the figure) and a second detection component (not labeled in the figure), wherein the first detection component is used to detect whether the commodity 100 is placed on one diagonal line of the rectangle, and the second detection component is used to detect whether the commodity 100 is placed on the straight side of the rectangle close to the outlet side of the commodity shelves 21. The aforementioned first detection component and second detection component can both be photoelectric sensors 3, which include an emitting end 31 and a receiving end 32 used in pairs. When the light emitted by the emitting end 31 can be received by the receiving end 32, that is, the light is closed, it indicates that there is no blocking object in the propagation path of the light, that is, there is no commodity 100 placed on the area of the platform frame 2221 matched with the light path, otherwise, if the light is not closed, it indicates that the commodity 100 is placed in the corresponding area.
[0048] In the technical solution, the first detection component and the second detection component are used to detect whether the commodity 100 is placed in the top loading area of the platform frame 2221, and especially the second detection component can detect the area close to the commodity shelves 21, and the arrangement of the two detection components can ensure accurate detection and judgment of whether the commodity 100 is placed in the commodity conveying assembly.
[0049] In some embodiments, the abnormal commodity storage area 12 is provided with a sealable door panel (not shown in the figure), and the abnormal commodity storage area 12 has a heat preservation structure, for example, a heat preservation cotton layer attached to the inner side of the door panel and the corresponding position of the cabinet body 1 and the abnormal commodity storage area 12, to ensure the satisfaction of the heat preservation requirement of the commodity 100 sent in, especially when the commodity 100 is a meal; and / or, the abnormal commodity storage area 12 has multiple layers of shelves (not shown in the figure), so as to improve the storage capacity of the abnormal commodity storage area 12 for abnormal commodities. In a specific embodiment, the shelves are four layers.
[0050] The commodity normal taking outlet 11 can be provided with multiple.
[0051] According to the embodiments of the utility model, a control method of the commodity vending cabinet is also provided, which includes the following steps:
[0052] When the commodity vending cabinet is powered on and restarted, it is detected whether the commodity 100 in the commodity vending cabinet is in an abnormal position state;
[0053] When it is detected that the commodity 100 is in an abnormal position state, the commodity conveying assembly and / or the commodity channel 21 are controlled to operate, so that the commodity 100 in the abnormal position is sent into the commodity normal taking outlet 11 or the abnormal commodity storage area 12.
[0054] In the technical scheme, when the commodity vending cabinet is powered on and restarted, it indicates that the commodity 100 has the possibility of an abnormal position, at this time, in order not to affect the subsequent order processing process, the control component of the commodity vending cabinet of the utility model detects the position of the commodity 100 through the corresponding detection component, and determines whether the commodity position is abnormal, and when the commodity position is in an abnormal state, the commodity conveying assembly and / or the commodity channel 21 are controlled to operate, so that the commodity 100 in the abnormal position is sent into the commodity normal taking outlet 11 or the abnormal commodity storage area 12, so as to effectively avoid the phenomenon that the commodity vending cabinet in the prior art cannot normally distribute the commodities corresponding to the orders after being powered on and restarted due to abnormal conditions, leading to distribution errors, and further hindering the purchase process of subsequent products, improving the user experience.
[0055] In some embodiments, the abnormal position state includes a first state, when it is detected that the commodity 100 is in the junction position of the commodity channel 21 and the commodity conveying assembly (that is, the position between the platform frame 2221 and the outlet of the commodity channel 21), it is determined that the commodity 100 is in the first state, for example, Figure 4As shown, at this time, first control the operation of the commodity channel 21 to make the commodity 100 completely sent to the commodity conveying assembly, then control the commodity conveying assembly to move to the abnormal commodity storage area 12, and control the operation of the commodity conveying assembly to send the commodity 100 on it into the abnormal commodity storage area 12, and then control the commodity conveying assembly to move back to the initial position. In a specific embodiment, the aforementioned initial position can be the position of the lower left corner of the commodity vending cabinet. Of course, the specific initial position can be reasonably selected according to actual needs, and the control of the commodity conveying assembly to move back to the initial position does not require the control system to record and save the specific position of the commodity conveying assembly, thereby simplifying the design of the electrical system.
[0056] In the technical solution, when it is detected that the commodity 100 is in a position abnormality and in a first state, that is, at the junction position of the commodity conveying assembly and the outlet of the commodity channel 21, first control the operation of the commodity channel 21 to make the commodity 100 completely sent to the commodity conveying assembly, to prevent the occurrence of situations such as damage to the commodity 100 or damage to the inspection card caused by controlling the movement of the commodity conveying assembly when the commodity 100 is in the first state, and then control the movement of the commodity conveying assembly to send the commodity 100 to the abnormal commodity storage area, and finally return to the initial position to wait for the subsequent order process.
[0057] It can be understood that whether the commodity 100 is in the first state can be detected by the aforementioned second detection component, that is, when the second detection component is the photoelectric sensor 3, at this time, the light emitted by the corresponding emission end 31 cannot be received by the receiving end 32 to form a light closure, indicating that the commodity 100 is in the first state.
[0058] Specifically referring to Figure 5 As shown, the position abnormality state also includes a second state. When it is detected that the commodity 100 is in the commodity normal taking outlet 11, it is determined that the commodity 100 is in the second state, and the operation of the commodity conveying assembly is controlled to prevent the commodity 100 from being on it, and then the commodity conveying assembly is controlled to move back to the initial position.
[0059] In the technical solution, the second state of the commodity 100 can be detected and determined by the photoelectric sensor 3 arranged in the commodity normal taking outlet 11. When the commodity 100 is in the second state, it indicates that the commodity 100 has been in the commodity normal taking outlet 11. Generally, the purchaser corresponding to the commodity 100 can normally take out the commodity 100, but there is a certain probability that the purchaser does not take out the commodity and part of the commodity is placed on the commodity conveying assembly. Therefore, at this time, the operation of the commodity conveying assembly is still controlled to push the commodity that may be on it into the commodity normal taking outlet 11, and then return to the initial position.
[0060] See details Figure 6 As shown, the abnormal position state also includes a third state. When it is detected that the product 100 is completely on the product conveying component, it is determined that the product 100 is in the third state. The product conveying component is controlled to move to the abnormal product storage area 12, and the product conveying component is controlled to operate to send the product 100 on it into the abnormal product storage area 12. Then, the product conveying component is controlled to move back to the initial position.
[0061] In some implementations, after the product 100 is sent into the abnormal product storage area 12, a prompt message is sent to remind maintenance personnel to handle the product 100 in the abnormal product storage area 12, such as prompting maintenance personnel to put the product 100 in the abnormal product storage area 12 back into the product channel 21.
[0062] It should be noted that if it is determined that the product 100 is not in an abnormal position, the product conveying component can be controlled to move directly to the initial position. At this time, the corresponding results can also be fed back to ensure the normal settlement of unsettled orders caused by the abnormal restart of the product vending cabinet.
[0063] The following combination Figure 7 The control logic flow for the product vending machine of this utility model when it is a food vending machine is further explained:
[0064] 1. After powering on again, check if the food pickup platform is in its initial position. If it is in the initial position, the food pickup process is currently in standby mode and does not require a reset. If it is not in the initial position, then process 2 needs to be executed.
[0065] 2. When the food collection platform is not in its initial position, check whether the photoelectric sensor at the food dispensing port (located inside the dispensing port) is closed. If the photoelectric sensor at the food dispensing port is not closed, it is visible... Figure 5 The second state shown indicates that the food collection platform is located at the food outlet, and the food collection process is in the state of pushing the food to the food outlet. At this time, the food collection platform pusher pushes the food out, and then the food collection platform pusher returns, the food collection platform resets, and the reset is complete. If the photoelectric sensor at the food outlet is closed, then process 3 needs to be executed.
[0066] 3. When the photoelectric sensor at the food dispensing outlet is closed, it indicates that the food collection platform is not at the food dispensing outlet. At this time, the status of the photoelectric sensor 2 on the food collection platform (i.e., the aforementioned first detection component, iAitong) is checked. If the photoelectric sensor 2 on the food collection platform is open, it indicates that the food is stuck in the gap between the food collection position (the exit of the goods channel 21) and the food collection platform. Figure 4The first state shown. At this time, the goods channel is driven to run, the goods channel push plate moves, the meal is pushed to the meal taking platform, and then the meal is sent to the abnormal meal outlet, and then the reset is completed. If the meal taking platform photoelectric sensor 2 is closed, process 4 needs to be performed.
[0067] 4、When the meal taking platform photoelectric sensor 2 is closed, it means that there is no meal stuck in the gap between the meal taking position and the meal taking platform. At this time, the state of the meal taking platform photoelectric sensor 1 (i.e. the first detection component mentioned above, the same below) is detected. If the photoelectric sensor 1 is closed, it means that there is no meal on the meal taking platform, and at this time the meal taking platform can be normally reset. If the photoelectric sensor 2 is open, it means that the meal that has not been pushed out last time is placed on the meal taking platform. It can be seen that Figure 6 The third state shown, the meal is sent to the abnormal meal outlet, and then the reset is completed.
[0068] Through the above detection and reset mode, it can be ensured that the goods vending cabinet completes the order not completed before power off after power on again, and there is no problem of meal dumping caused by direct reset after power off, which improves the reliability of the unit. And the order after reset can be sent to the abnormal meal outlet for heat preservation, preventing meal temperature abnormality and improving user experience.
[0069] Those skilled in the art can easily understand that the advantageous technical features of each mode described above can be freely combined and superimposed without conflict.
[0070] The above only describes the preferred embodiments of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the present application.
