Description

Technical Field

[0001] This invention belongs to the field of merchandise vending machine design technology, specifically relating to a merchandise vending machine and its control method. Background Technology

[0002] In related technologies, taking food vending machines as an example, after a power outage or network failure, some motion mechanisms may not respond. The mainboard cannot read the previous motion state after power is restored, so the relevant mechanisms reset immediately upon power-up, such as retracting the push rod, closing the door, and moving the food pickup platform to its initial position. However, if there are items on the food delivery platform (e.g., the food delivery platform) that have not been pushed to the pickup / dispensing port (e.g., the food dispensing port) (orders not completed before the abnormal shutdown), the control system detects the items on the platform and suspends subsequent delivery commands. This leads to incorrect product delivery, affecting the subsequent purchase process and reducing the user experience. Summary of the Invention

[0003] Therefore, the present invention provides a vending machine and its control method, which can overcome the technical problem in the related art that when the vending machine is powered on again after an abnormal shutdown and there are goods on the conveyor platform, the subsequent product delivery process cannot continue, resulting in delivery errors, affecting the subsequent product purchase process, and reducing the user experience.

[0004] To address the aforementioned problems, the present invention provides a vending machine, comprising a cabinet shell with a normal product retrieval outlet and an abnormal product storage area. The cabinet shell contains a receiving space, which includes a product conveying assembly and a product channel. Products in the product channel can be conveyed to the product conveying assembly, which carries the products and moves them to either the normal product retrieval outlet or the abnormal product storage area, thereby transporting the products carried on the product conveying assembly to either the normal product retrieval outlet or the abnormal product storage area.

[0005] In some embodiments, the merchandise conveying assembly includes a lifting platform and a traversing platform, wherein the traversing platform is slidably connected to the top surface of the lifting platform so as to be driven to reciprocate horizontally, the lifting platform can be controlled to lift and lower, and the merchandise can be carried on the top surface of the traversing platform; and / or, the merchandise vending machine is a food vending machine.

[0006] In some embodiments, the transverse platform includes a platform frame and a plurality of parallel, spaced rollers connected within the platform frame, and the goods conveyor has a conveying track, the conveying direction of which is perpendicular to the axial direction of the rollers in the horizontal plane.

[0007] In some embodiments, the transverse platform further includes a platform pusher for pushing the goods on the roller along the axial direction of the roller; and / or, the goods conveyor also has a conveyor pusher for pushing the goods on the conveyor belt along the conveying direction of the conveyor belt.

[0008] In some embodiments, the platform frame has a first region close to the merchandise aisle and a second region away from the merchandise aisle, wherein each roller in the first region is an active rotating roller and each roller in the second region is a driven rotating roller.

[0009] In some embodiments, the projection of the platform frame onto the horizontal plane is a rectangle, and the platform frame is provided with a first detection component and a second detection component. The first detection component is used to detect whether the product is placed on one diagonal of the rectangle, and the second detection component is used to detect whether the product is placed on the straight edge of the rectangle near the exit side of the product channel.

[0010] In some implementations, both the first detection component and the second detection component are photoelectric sensors.

[0011] In some embodiments, the abnormal goods storage area is provided with an openable and closable sealed door panel, and the abnormal goods storage area has a heat insulation structure; and / or, the abnormal goods storage area has multi-layer shelves.

[0012] The present invention also provides a control method for the above-described merchandise vending machine, comprising the following steps:

[0013] When the vending machine is powered on and restarted, it is detected whether the goods inside the vending machine are in an abnormal position.

[0014] When the product is detected to be in an abnormal position, the operation of the product conveying component and / or product channel is controlled so that the abnormal product is sent to the normal product take-out port or the abnormal product storage area.

[0015] In some implementations, the abnormal position state includes a first state. When the product is detected to be at the junction of the product channel and the product conveying component, it is determined that the product is in the first state. First, the product channel is controlled to operate so that the product is completely fed onto the product conveying component. Then, the product conveying component is controlled to move to the abnormal product storage area and is controlled to operate to send the product on it into the abnormal product storage area. After that, the product conveying component is controlled to move back to the initial position.

[0016] In some implementations, the abnormal position state includes a second state. When the product is detected to be in the normal product dispensing outlet, it is determined that the product is in the second state, and the product conveying component is controlled to operate to prevent the product from being placed on it. Then, the product conveying component is controlled to move back to the initial position.

[0017] In some implementations, the abnormal position state includes a third state. When it is detected that the product is completely on the product conveying component, the product is determined to be in the third state. The product conveying component is then controlled to move to the abnormal product storage area, and the product conveying component is controlled to operate to send the product on it into the abnormal product storage area. After that, the product conveying component is controlled to move back to the initial position.

[0018] The present invention provides a vending machine and its control method, which have the following beneficial effects:

[0019] The cabinet shell is constructed with both a normal product retrieval outlet and a storage area for abnormal products. The product conveying component can transport the products it carries to the normal product retrieval outlet or the storage area for abnormal products according to the actual situation. This effectively avoids the phenomenon in the existing technology where the vending machine cannot deliver the products corresponding to the order after restarting due to abnormal conditions, resulting in delivery errors and hindering the subsequent product purchase process. This improves the user experience and enhances the reliability of the product. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

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

[0033] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0034] See Figures 1 to 7 As shown in the figure, according to an embodiment of the present invention, a vending machine is provided, including a cabinet shell 1. The cabinet shell 1 is constructed with a normal product retrieval outlet 11 and an abnormal product storage area 12. The cabinet shell 1 has a accommodating space (not labeled in the figure), and the accommodating space has a product conveying component (not labeled in the figure) and a product channel 21. Products 100 in the product channel 21 can be conveyed to the product conveying component. The product conveying component can carry the products 100 and move them to the normal product retrieval outlet 11 or the abnormal product storage area 12, so as to convey the products 100 carried on the product conveying component to the normal product retrieval outlet 11 or the abnormal product storage area 12. In a specific embodiment, the aforementioned vending machine is a food vending machine, the aforementioned product 100 is specifically a meal, the aforementioned normal product retrieval outlet 11 is also a food dispensing outlet, the aforementioned abnormal product storage area 12 is also an abnormal food dispensing outlet, and the aforementioned product conveying component corresponds to a food retrieval platform. It should be noted that the aforementioned normal product retrieval outlet 11 is specifically the temporary storage location for products selected in normal orders, while the abnormal product storage area 12 is specifically the temporary storage location for products corresponding to orders that cannot be completed due to abnormal malfunctions such as power outages or system crashes in the vending machine.

[0035] In this technical solution, a normal product retrieval outlet 11 and an abnormal product storage area 12 are constructed on the outer shell 1 of the cabinet. The product conveying component can convey the product 100 it carries to the normal product retrieval outlet 11 or the abnormal product storage area 12 according to the actual situation. This effectively avoids the phenomenon in the prior art where the vending machine cannot deliver the product corresponding to the order normally after restarting due to abnormal conditions, resulting in delivery errors and hindering the subsequent product purchase process. This improves the user experience and enhances the reliability of the product.

[0036] In a feasible embodiment, a corresponding display screen 13 can also be installed on the outer shell 1 of the vending machine. The display screen 13 is specifically a touch screen. When the vending machine restarts after an abnormal situation, the maintenance personnel can issue corresponding control commands through the touch screen to control the product conveying component to move to the abnormal product storage area 12 and send the product 100 it carries into the abnormal product storage area 12, that is, to clear the product conveying component to continue the subsequent order processing process. Of course, the movement of the aforementioned product conveying component can also be achieved by manual operation in some special cases. As a preferred implementation method, the movement of the aforementioned product conveying component can be controlled by the automatic control of the relevant control components inside the vending machine.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] In some embodiments, the platform frame 2221 has a first region (not shown in the figure) near the goods aisle 21 and a second region (not shown in the figure) away from the goods aisle 21. Each roller 2222 in the first region is an active rotating roller, and each roller 2222 in the second region is a driven rotating roller. The aforementioned active rotating roller is a roller 2222 that is equipped with a corresponding rotational power component (e.g., a rotary motor) to enable it to rotate self-driven. The aforementioned driven rotating roller is one that does not have its own drive component; it is rotatably connected to a corresponding mounting carrier via a rotating shaft, and its rotational power comes from the static friction force with a certain moving speed carried on it.

[0044] In this technical solution, each roller 2222 in the first area adjacent to the goods channel 21 is set as an active rotating roller, which can use the self-driving ability of each roller 2222 to transfer the goods delivered from the goods channel 21 more efficiently and smoothly. Meanwhile, each roller 2222 in the second area far from the goods channel 21 is a driven rotating roller, thus reducing the overall manufacturing cost of the equipment.

[0045] See details Figure 3As shown, in some embodiments, the projection of the platform frame 2221 onto the horizontal plane is rectangular. 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). The first detection component is used to detect whether the product 100 is placed on one diagonal of the rectangle, and the second detection component is used to detect whether the product 100 is placed on the straight edge of the rectangle near the exit side of the product channel 21. The aforementioned first detection component and second detection component can both be photoelectric sensors 3. The photoelectric sensor 3 includes a transmitter 31 and a receiver 32 paired with it. When the light emitted by the transmitter 31 can be received by the receiver 32, that is, when a light closure is formed, it indicates that there is no object blocking the propagation path of the light, that is, no product 100 is placed in the area of ​​the platform frame 2221 that matches the light path. Otherwise, if the aforementioned light closure is not formed, it indicates that the product 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 the product 100 is placed in the top bearing area of ​​the platform frame 2221. In particular, the second detection component can detect the area adjacent to the product channel 21. At the same time, the aforementioned two sets of detection components can ensure accurate detection and judgment of the presence or absence of the product 100 in the product conveying component.

[0047] In some embodiments, the abnormal goods storage area 12 is equipped with an openable and closable sealed door (not shown in the figure), and the abnormal goods storage area 12 has a heat-insulating structure. This heat-insulating structure is, for example, attached to the inner side of the sealed door and the heat-insulating cotton layer at the corresponding position of the cabinet shell 1 and the abnormal goods storage area 12, to ensure that the heat-insulating requirements of the delivered goods 100 are met, especially when the goods 100 are meals; and / or, the abnormal goods storage area 12 has multi-layer shelves (not shown in the figure), thus increasing the storage capacity of the abnormal goods storage area 12 for abnormal goods. In one specific embodiment, the aforementioned shelves have four layers.

[0048] Multiple normal product outlets 11 can be set.

[0049] According to an embodiment of the present invention, a control method for the above-described merchandise vending machine is also provided, comprising the following steps:

[0050] When the vending machine is powered on and restarted, it is detected whether the product 100 inside the vending machine is in an abnormal position.

[0051] When the product 100 is detected to be in an abnormal position, the product conveying component and / or product channel 21 are controlled to operate so that the abnormal product 100 is sent into the normal product outlet 11 or the abnormal product storage area 12.

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

[0053] In some embodiments, the abnormal position state includes a first state, whereby the product 100 is determined to be in the first state when it is detected that the product 100 is at the junction of the product channel 21 and the product conveying assembly (i.e., the position between the aforementioned platform frame 2221 and the outlet of the product channel 21). Figure 4 As shown, at this time, the merchandise conveyor 21 is first controlled to operate so that the merchandise 100 is completely fed onto the merchandise conveying component. Then, the merchandise conveying component is controlled to move to the abnormal merchandise storage area 12, and the merchandise conveying component is controlled to operate to send the merchandise 100 on it into the abnormal merchandise storage area 12. After that, the merchandise conveying component is controlled to move back to the initial position. In a specific embodiment, the aforementioned initial position can be the lower left corner of the merchandise vending machine. Of course, the specific initial position can be reasonably selected according to actual needs. Controlling the merchandise conveying component to move back to the initial position eliminates the need for the control system to record and save the specific position of the merchandise conveying component, simplifying the electrical system design.

[0054] In this technical solution, when an abnormal position of product 100 is detected and it is in the first state, that is, at the junction of the product conveying component and the product channel 21, the product channel 21 is first controlled to operate so that product 100 can be completely delivered to the product conveying component. This prevents damage to product 100 or damage due to jamming during inspection caused by controlling the movement of the product conveying component when product 100 is in the first state. After product 100 is delivered to the product conveying component, the product conveying component is then controlled to move the product 100 to the abnormal product storage area. Finally, it returns to the initial position to wait for subsequent order processing.

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

[0056] See details Figure 5 As shown, the abnormal position state also includes a second state. When the product 100 is detected to be in the normal product outlet 11, it is determined that the product 100 is in the second state. The product conveying component is controlled to operate to prevent the product 100 from being on it. Then, the product conveying component is controlled to move back to the initial position.

[0057] In this technical solution, the second state of the product 100 can be determined by the photoelectric sensor 3 installed in the normal product retrieval outlet 11. When the product 100 is in the second state, it means that the product 100 is in the normal product retrieval outlet 11. Generally speaking, the buyer corresponding to the product 100 can take the product 100 out normally. However, there is also a certain probability that the buyer has not taken out the product and part of the product is placed on the product conveying component. Therefore, at this time, the product conveying component is still controlled to push the product that may be on it into the normal product retrieval outlet 11, and then returns to the initial position.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] The following combination Figure 7The control logic flow for the product vending machine of this invention when it is a food vending machine is further explained:

[0062] 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.

[0063] 2. When the food collection platform is not in its initial position, check whether the photoelectric sensor at the food outlet (located inside the outlet) is closed. If the photoelectric sensor at the food outlet is not closed, it will be 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.

[0064] 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 4 The first state is shown. At this time, the driveway operates, the driveway pusher moves, pushing the food to the food collection platform, then delivering the food to the abnormal food outlet, and finally resetting. If the photoelectric sensor 2 on the food collection platform is closed, then process 4 needs to be executed.

[0065] 4. When photoelectric sensor 2 on the food pickup platform is closed, it indicates that no food is stuck in the gap between the pickup position and the platform. At this time, the status of photoelectric sensor 3 (the aforementioned first detection component, hereinafter the same) is checked. If photoelectric sensor 3 is closed, it means there is no food on the platform, and the platform can be reset normally. If photoelectric sensor 2 is open, it means there is food on the platform that was not pushed out last time. Figure 6 The third state, as shown, involves sending the food to the abnormal food outlet and then resetting it.

[0066] Through the aforementioned detection and reset methods, it can be ensured that orders not completed before the power outage are finished after the vending machine is powered back on, preventing the food from tipping over due to direct reset after a power outage, thus improving the reliability of the unit. Furthermore, reset orders are delivered to the properly insulated food dispensing chute to prevent abnormal food temperatures, improving the user experience.

[0067] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0068] The above description is merely 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 principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
