DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0032] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90° or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0033] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0034] See also Figures 1 to 7 As shown, according to an embodiment of the present invention, there is provided a commodity vending cabinet, comprising a cabinet shell 1, on which a normal commodity outlet 11 and an abnormal commodity storage area 12 are constructed, and a storage space (not labeled in the figure) is provided in the cabinet shell 1, and a commodity conveying assembly (not labeled in the figure) and a commodity aisle 21 are provided in the storage space, and commodities 100 in the commodity aisle 21 can be conveyed to the commodity conveying assembly, and the commodity conveying assembly can carry the commodities 100 and move to the normal commodity outlet 11 or the abnormal commodity storage area 12, so as to convey the commodities 100 carried by the commodity conveying assembly to the normal commodity outlet 11 or the abnormal commodity storage area 12. In a specific embodiment, the aforementioned commodity vending cabinet is specifically a meal vending cabinet, and the corresponding aforementioned commodity 100 is specifically a meal, the aforementioned normal commodity outlet 11 is also a meal outlet, the aforementioned abnormal commodity storage area 12 is also an abnormal meal outlet, and the aforementioned commodity conveying assembly corresponds to a meal pickup platform. It should be noted that the normal commodity take-out outlet 11 is a temporary storage location for commodities purchased and selected for normal orders, while the abnormal commodity storage area 12 is a temporary storage location for commodities corresponding to an order that cannot be completed due to abnormal faults such as power outage or freeze of the commodity vending cabinet.

[0035] In this technical solution, a normal commodity outlet 11 and an abnormal commodity storage area 12 are simultaneously constructed on the cabinet shell 1, and the commodity conveying component can convey the commodity 100 carried thereon to the normal commodity outlet 11 or the abnormal commodity storage area 12 according to actual conditions, thereby effectively avoiding the phenomenon in which the commodity selling cabinet in the prior art cannot normally deliver the commodities corresponding to the order after restarting and powering on due to abnormal circumstances, resulting in delivery errors, and further hindering the subsequent product purchase process, thereby improving the user experience and improving the reliability of the product.

[0036] In a feasible embodiment, a corresponding display screen 13 can also be provided on the cabinet shell 1 of the merchandise vending cabinet. The display screen 13 is specifically a touch screen. When the merchandise vending cabinet restarts and powers on due to an abnormal condition, the maintenance personnel can issue corresponding control instructions through the touch screen to control the merchandise conveying component to move to the abnormal merchandise storage area 12 and deliver the merchandise 100 carried on it into the abnormal merchandise storage area 12, that is, to clear the merchandise conveying component to continue the subsequent order processing flow. Of course, the movement of the aforementioned merchandise conveying component can also be achieved by manual control in some special cases. As a more preferred implementation method, the movement of the aforementioned merchandise conveying component can be controlled by automatic control of relevant control components in the merchandise vending cabinet.

[0037] In some embodiments, the commodity conveying assembly includes a lifting platform 221 and a transverse platform 222, wherein the transverse platform 222 is slidably connected to the top surface of the lifting platform 221 so as to be driven to reciprocate and transversely move in the horizontal direction, the lifting platform 221 can be controlled to rise and fall, and the commodity 100 can be carried on the top surface of the transverse platform 222. The transverse platform 222 and the lifting platform 221 can specifically adopt a screw module in the prior art.

[0038] In this technical solution, a lifting platform 221 and a transverse moving platform 222 are used to form a commodity conveying component, and a lifting and transverse moving composite moving mode is adopted, which makes the movement more stable and ensures the smooth conveyance of commodities.

[0039] In some embodiments, see Figure 2 As shown, the transverse moving platform 222 includes a platform frame 2221 and a plurality of parallel and spaced rollers 2222 connected to the platform frame 2221. The commodity aisle 21 has a conveying belt 211, and the conveying direction of the conveying belt 211 is perpendicular to the axial direction of the roller 2222 in the horizontal plane.

[0040] In this technical solution, the commodity 100 is conveyed from the commodity aisle 21 to the bearing surface formed by each roller 2222 through the conveying of the conveying crawler 211, which can make the overall structural design of the commodity vending cabinet more reasonable.

[0041] In some embodiments, the transverse platform 222 further includes a platform push plate 2223, which is used to push the commodity 100 on the roller 2222 along the axial direction of the roller 2222; and / or the commodity aisle 21 further includes an aisle push plate 212, which is used to push the commodity 100 on the conveying crawler 211 along the conveying direction of the conveying crawler 211. The aforementioned platform push plate 2223 and the aisle push plate 212 can use electric push rods to achieve their telescopic and outward pushing functions.

[0042] In this technical solution, by arranging a platform push plate 2223 on the transverse platform 222, the goods 100 placed on the roller 2222 can be smoothly pushed to the aforementioned normal goods removal outlet 11 or the abnormal goods storage area 12, and by arranging an aisle push plate 212 on the aisle push plate 212, the goods 100 in the goods aisle 21 can be smoothly pushed out synchronously with the conveyor belt 211, especially for goods 100 with a larger height, uniform force on the goods 100 in the height direction can be achieved, and the goods 100 can be delivered at a higher pushing speed.

[0043] In some embodiments, the platform frame 2221 has a first area (not labeled in the figure) close to the commodity aisle 21 and a second area (not labeled in the figure) away from the commodity aisle 21, and each of the rollers 2222 in the first area is an active rotating roller, and each of the rollers 2222 in the second area is a driven rotating roller. The aforementioned active rotating roller is a roller 2222 that is equipped with a corresponding rotating power component (such as a rotary motor) to enable it to rotate by itself, and the aforementioned driven rotating roller is a roller that does not have a driving component, and is rotatably connected to the corresponding mounting carrier by a rotating shaft, and its rotation power comes from the static friction force with a certain moving speed carried thereon.

[0044] In this technical solution, each roller 2222 in the first area adjacent to the commodity aisle 21 is set as an active rotating roller, which can utilize the self-driving ability of each roller 2222 to transfer the commodities sent out from the commodity aisle 21 more efficiently and smoothly, while each roller 2222 in the second area farther from the commodity aisle 21 is a driven rotating roller, thereby reducing the overall manufacturing cost of the equipment.

[0045] See Figure 3As shown, 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 a diagonal line of the rectangle, and the second detection component is used to detect whether the commodity 100 is placed on the straight edge of the rectangle near the exit of the commodity cargo lane 21. The first detection component and the second detection component can both be photoelectric sensors 3, which include a transmitting end 31 and a receiving end 32 used in pair with the transmitting end 31. When the light emitted by the transmitting end 31 can be received by the receiving end 32, that is, the light is closed, it means that there is no obstruction on the propagation path of the light, that is, it means that the commodity 100 is not placed in the area of ​​the platform frame 2221 that matches the light path, otherwise, if the light is not closed, it means that the commodity 100 is placed in the corresponding area.

[0046] In this technical solution, a first detection component and a second detection component are used to detect whether goods 100 are placed in the top bearing area of ​​the platform frame 2221. In particular, the second detection component can detect the area adjacent to the commodity aisle 21. At the same time, the two groups of detection components are arranged to ensure accurate detection and judgment of the presence or absence of commodities 100 in the commodity conveying assembly.

[0047] In some embodiments, the abnormal commodity storage area 12 is provided with an openable and closable sealed door panel (not marked in the figure), and the abnormal commodity storage area 12 has a heat preservation structure, which is attached to the inner side of the sealed door panel and the heat preservation cotton layer at the corresponding position of the cabinet shell 1 and the abnormal commodity storage area 12, so as to ensure that the heat preservation requirements of the delivered commodity 100 are met, especially when the commodity 100 is a meal; and / or, the abnormal commodity storage area 12 has a multi-layer rack (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 rack has four layers.

[0048] The aforementioned normal commodity removal outlet 11 may be provided in plurality.

[0049] According to an embodiment of the present invention, there is also provided a control method for the above-mentioned commodity vending cabinet, comprising the following steps:

[0050] 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;

[0051] When it is detected that the commodity 100 is in an abnormal position, the commodity conveying component and / or the commodity cargo lane 21 are controlled to operate so that the commodity 100 in the abnormal position is sent to the normal commodity removal outlet 11 or the abnormal commodity storage area 12.

[0052] In this technical solution, when the merchandise vending cabinet is powered on and restarted, it indicates that there is a possibility that the position of the merchandise 100 is abnormal. At this time, in order not to affect the subsequent order processing flow, the control component of the merchandise vending cabinet of the present invention detects the position of the merchandise 100 through the corresponding detection component, and determines whether the merchandise position is abnormal. When the merchandise position is in an abnormal state, the merchandise conveying component and / or the merchandise aisle 21 are controlled to operate so that the merchandise 100 with an abnormal position is delivered to the normal merchandise take-out outlet 11 or the abnormal merchandise storage area 12. This can effectively avoid the phenomenon that the merchandise vending cabinet in the prior art cannot normally deliver the merchandise corresponding to the order after restarting and powering on due to an abnormal situation, resulting in delivery errors, thereby hindering the subsequent product purchase process, thereby improving the user experience.

[0053] In some embodiments, the abnormal position state includes a first state. When it is detected that the commodity 100 is at the junction of the commodity aisle 21 and the commodity conveying assembly (that is, the position between the aforementioned platform frame 2221 and the exit of the commodity aisle 21), it is determined that the commodity 100 is in the first state, such as Figure 4 As shown, at this time, the commodity cargo lane 21 is first controlled to operate so that the commodity 100 is completely delivered to the commodity conveying assembly, and then the commodity conveying assembly is controlled to move to the abnormal commodity storage area 12, and the commodity conveying assembly is controlled to operate to deliver the commodity 100 thereon into the abnormal commodity storage area 12, and then the commodity conveying assembly is controlled 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 commodity conveying assembly is controlled to move back to the initial position, and there is no need for the control system to record and save the specific position of the commodity conveying assembly, thereby simplifying the electrical system design.

[0054] In this technical solution, when it is detected that the commodity 100 is in an abnormal position and is in the first state, that is, at the junction of the commodity conveying component and the exit of the commodity aisle 21, the commodity aisle 21 is first controlled to operate so that the commodity 100 can be completely delivered to the commodity conveying component, to prevent the commodity 100 from being damaged or damaged due to jamming due to re-inspection caused by controlling the movement of the commodity conveying component when the commodity 100 is in the first state. After the commodity 100 is delivered to the commodity conveying component, the movement of the commodity conveying component is controlled to deliver the commodity 100 to the abnormal commodity storage area, and finally returns to the initial position to wait for processing of subsequent order processes.

[0055] It can be understood that whether the product 100 is in the first state can be detected by the aforementioned second detection component, that is, when the second detection component is a photoelectric sensor 3, the light emitted by its corresponding transmitting end 31 cannot be received by the receiving end 32 to form a light closure, which means that the product 100 is in the first state.

[0056] See Figure 5 As shown, the abnormal position state also includes a second state. When it is detected that the commodity 100 is at the normal commodity removal outlet 11, it is determined that the commodity 100 is in the second state, the commodity conveying component is controlled to operate to prevent the commodity 100 from being thereon, and then the commodity conveying component is controlled to move back to the initial position.

[0057] In this technical solution, the second state of the commodity 100 can be detected and determined by the photoelectric sensor 3 arranged in the normal commodity removal outlet 11. When the commodity 100 is in the second state, it means that the commodity 100 is already in the normal commodity removal outlet 11. Generally speaking, the purchaser corresponding to the commodity 100 can take out the commodity 100 normally, but there is also a certain probability that the purchaser has not taken out the commodity and part of the commodity is placed on the commodity conveying component. Therefore, at this time, the commodity conveying component is still controlled to operate to push the commodities that may be on it into the normal commodity removal outlet 11, and then return to the initial position.

[0058] See Figure 6 As shown, the abnormal position state also includes a third state. When it is detected that the commodity 100 is completely on the commodity conveying component, it is determined that the commodity 100 is in the third state, the commodity conveying component is controlled to move to the abnormal commodity storage area 12, and the commodity conveying component is controlled to operate to deliver the commodity 100 thereon into the abnormal commodity storage area 12, and then the commodity conveying component is controlled to move back to the initial position.

[0059] In some embodiments, after the commodity 100 is sent into the abnormal commodity storage area 12, a prompt message is sent to prompt the maintenance personnel to dispose of the commodity 100 in the abnormal commodity storage area 12, for example, prompting the maintenance personnel to put the commodity 100 in the abnormal commodity storage area 12 back into the commodity aisle 21.

[0060] It should be noted that if it is determined that there is no position abnormality with the commodity 100, the commodity 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 the unsettled order process caused by the abnormal restart of the commodity vending cabinet.

[0061] The following combination Figure 7The control logic flow of the product vending cabinet of the present invention when it is a meal vending cabinet is further described:

[0062] 1. After powering on again, check whether the meal pickup platform is in the initial position. If it is in the initial position, it means that the current meal pickup process is in standby mode and does not need to be reset. If it is not in the initial position, process 2 needs to be executed.

[0063] 2. When the food pick-up platform is not in the initial position, check whether the photoelectric sensor of the food outlet (located in the food outlet) is closed. If the photoelectric sensor of the food outlet is not closed, it can be seen Figure 5 The second state shown indicates that the meal-taking platform is at the meal outlet, and the meal-taking process is in the state of pushing the meal to the meal outlet. At this time, the meal-taking platform push plate is driven to push the meal out, and then the meal-taking platform push plate returns, and the meal-taking platform is reset, and the reset is completed. If the photoelectric sensor at the meal outlet is closed, process 3 needs to be executed.

[0064] 3. When the photoelectric sensor of the meal outlet is closed, it means that the meal pick-up platform is not at the meal outlet. At this time, the state of the photoelectric sensor 2 of the meal pick-up platform (that is, the first detection component mentioned above, the like pass) is detected. If the photoelectric sensor 2 of the meal pick-up platform is disconnected, it means that the food is stuck in the gap between the meal pick-up position (the exit of the commodity aisle 21) and the meal pick-up platform. Figure 4 The first state shown. At this time, the cargo lane is driven to run, the cargo lane push plate moves, the food is pushed to the meal pickup platform, and then the food is sent to the abnormal meal outlet, and then reset. If the photoelectric sensor 2 of the meal pickup platform is closed, process 4 needs to be executed.

[0065] 4. When the photoelectric sensor 2 of the meal-taking platform is closed, it means that there is no food stuck in the gap between the meal-taking position and the meal-taking platform. At this time, the state of the photoelectric sensor 1 (that is, the first detection component mentioned above, the same below) of the meal-taking platform is detected. If the photoelectric sensor 1 is closed, it means that there is no food on the meal-taking platform, and the meal-taking platform can be reset normally. If the photoelectric sensor 2 is disconnected, it means that there is food on the meal-taking platform that was not pushed out last time. Figure 6 In the third state shown, the food is delivered to the abnormal food outlet and then reset.

[0066] Through the above detection and reset method, it can ensure that the unfinished orders before the power failure are completed after the commodity vending cabinet is powered on again, and there will be no problem of food dumping due to direct reset after power failure, which improves the reliability of the unit. In addition, the restarted orders can be sent to the abnormal food outlet with insulation to prevent abnormal food temperature, which improves the user experience.

[0067] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention. These improvements and variations should also be regarded as the protection scope of the present invention.
