Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent vending cabinets, in particular to a replenishment control method and device of an intelligent vending cabinet and the intelligent vending cabinet. BACKGROUND

[0002] With the rapid development of the economy and society and the progress of the times, consumers' demand for goods is becoming more and more diversified, extending to all aspects of life. For example, a considerable number of workers cannot have meals during normal meal times due to the particularity of working hours and working environment, which leads to fewer choices or un-fresh meals. Therefore, the emergence of the meal delivery cabinet can solve the above-mentioned problems of fewer choices or un-fresh meals.

[0003] The meal delivery cabinet belongs to an intelligent vending cabinet. The intelligent vending cabinet includes at least one goods channel, and each goods channel is provided with a conveyor belt. An article (such as a lunch box) can be placed on the conveyor belt one by one according to the position, and the article moves from the inside of the goods channel to the outside of the goods channel along with the conveyor belt to realize goods delivery. The goods channel of the intelligent vending cabinet has a certain depth, and the side close to the cabinet door is the outside of the goods channel, and the side close to the back plate is the inside of the goods channel. A push plate is fixed on the conveyor belt, and when the goods channel is completed, the push plate is located at the innermost side of the goods channel (i.e. zero or origin).

[0004] When goods need to be delivered, the conveyor belt motor rotates forward, and the conveyor belt moves outward. Since the push plate is fixed on the conveyor belt, the push plate also moves outward and pushes the article out. When the push plate pushes out the last article, the push plate is located at the outermost position of the goods channel. Since the current intelligent vending cabinet goods channel conveyor belt motor can only rotate forward, the staff needs to manually push the push plate of the conveyor belt back to the zero position at the innermost side of the goods channel to replenish the articles from the inside to the outside, which is very low in efficiency. Moreover, since the height of the intelligent vending cabinet is high and the depth of the goods channel is deep, when the top or bottom goods channel is replenished, the article needs to be manually pushed to the innermost side of the goods channel, so the difficulty of replenishment is also great.

[0005] At present, there is no effective solution to the problem of low replenishment efficiency and great replenishment difficulty of the intelligent vending cabinet in the prior art. SUMMARY

[0006] The embodiments of the present application provide a replenishment control method and device of an intelligent vending cabinet and the intelligent vending cabinet to at least solve the problem of low replenishment efficiency and great replenishment difficulty of the intelligent vending cabinet in the prior art.

[0022] if the article is placed askew, controlling the conveyor belt motor to stop operating, and outputting an askew prompt information, and when receiving a correction completion instruction, controlling the conveyor belt motor to continue operating in the first direction until the outermost position is empty;

[0023] if the article is not placed askew, controlling the conveyor belt motor to continue operating in the first direction until the outermost position is empty.

[0024] Optionally, two offset sensors are symmetrically arranged between the outermost first position and the outermost second position of each cargo channel;

[0025] Detecting whether the placed item is misaligned includes:

[0026] If the time difference between the signals received by the two offset sensors is less than or equal to a first preset time, it is determined that the item is not misplaced.

[0027] If the time difference between the signals received by the two offset sensors is greater than the first preset time, it is determined that the item is misplaced.

[0028] Optionally, after confirming that the item is not misplaced, the method further includes:

[0048] It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that described herein.

[0049] The optional embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0050] The intelligent vending cabinet includes at least one goods channel, which has a certain depth, and the goods channel outside is close to the cabinet door and the goods channel inside is close to the back plate. Each goods channel is provided with a conveyor belt, and at least two positions are provided on the conveyor belt. The goods can be placed on the conveyor belt one by one according to the position, and the goods move from the goods channel inside to the goods channel outside along with the conveyor belt to realize goods delivery.

[0051] The embodiment of the present application provides a replenishment control method of an intelligent vending cabinet, which can be a meal delivery cabinet.

[0052] Figure 1 The flowchart of the replenishment control method of the intelligent vending cabinet provided by the embodiment of the present application is shown in Figure 1 The method comprises the following steps:

[0053] S101, determining a goods channel that needs to be replenished, and entering a replenishment mode.

[0054] S102, detecting that an outermost position of the goods channel is placed with goods.

[0055] S103, controlling a conveyor belt motor of the goods channel to operate in a first direction to transport the goods to the inside of the goods channel until the conveyor belt motor is controlled to stop operating when the outermost position is empty, and continuing to detect whether the outermost position is placed with goods.

[0056] S104, when it is detected that the push plate on the conveying belt reaches the preset position of the innermost side of the goods channel, prompt information is output to prompt the staff to confirm whether the goods replenishment of the goods channel is completed.

[0057] The conveying belt motor operates in a first direction to convey the goods to the inner side of the goods channel, and operates in a second direction to convey the goods to the outer side of the goods channel. The conveying belt motor supports forward rotation and reverse rotation, and the first direction and the second direction can be determined according to the actual installation condition. If the first direction is forward rotation, the second direction is reverse rotation. If the first direction is reverse rotation, the second direction is forward rotation.

[0058] In the goods replenishment mode, the staff places a goods at the outermost position of the goods channel, and the conveying belt motor is controlled to operate in the first direction to convey the goods to the inner side of the goods channel, so that the outermost position is emptied, and the staff continues to place goods.

[0059] The preset position of the innermost side of the goods channel refers to the zero position. If the push plate on the conveying belt reaches the zero position, it indicates that the conveying belt does not need to continue to operate in the first direction for goods replenishment.

[0060] In the goods replenishment mode, the staff places a goods at the outermost position of the goods channel, and the conveying belt motor is controlled to operate in the first direction to convey the goods to the inner side of the goods channel, so that the outermost position is emptied, and the staff continues to place goods.

[0061] When it is detected that the push plate on the conveying belt reaches the preset position of the innermost side of the goods channel, the outermost position of the goods channel is empty at this time, and after the prompt information is output, the staff can place the last goods at the outermost position to complete the goods replenishment of the goods channel, or not.

[0062] Specifically, after outputting the prompt information, the method further comprises: receiving a restocking completion instruction in response to the prompt information; detecting whether an article is placed in the outermost position of the goods channel; if the article is placed in the outermost position, exiting the restocking mode; if the article is not placed in the outermost position, controlling the conveyor belt motor to operate in the second direction to transport the article to the outside of the goods channel so that the article is placed in the outermost position, and exiting the restocking mode. After exiting the restocking mode, the vending mode can be entered.

[0063] The embodiment can ensure that the outermost position of the goods channel of the intelligent vending cabinet has an article, so as to facilitate article delivery.

[0064] In one embodiment, after controlling the conveyor belt motor to stop operating until the outermost position is empty, the method further comprises: receiving a restocking completion instruction without outputting the prompt information; controlling the conveyor belt motor to operate in the second direction to transport the article to the outside of the goods channel so that the article is placed in the outermost position, and exiting the restocking mode.

[0065] The embodiment transports the article in the second outermost position of the goods channel (i.e., the second position in the direction from the outside of the goods channel to the inside of the goods channel) to the first outermost position (i.e., the first position in the direction from the outside of the goods channel to the inside of the goods channel, also referred to as the outermost position) in the case that the staff actively confirms the completion of restocking, and ensures that the outermost position of the intelligent vending cabinet has an article.

[0066] Considering that the position and angle of the article placed in the goods channel by the staff may be offset, the embodiment further comprises, after controlling the conveyor belt motor of the goods channel to operate in the first direction: detecting whether the placed article is skewed; if the article is skewed, controlling the conveyor belt motor to stop operating and outputting a skew prompt information, and when a correction completion instruction is received, controlling the conveyor belt motor to continue operating in the first direction until the outermost position is empty; if the article is not skewed, controlling the conveyor belt motor to continue operating in the first direction until the outermost position is empty.

[0067] The embodiment can effectively detect whether the article placed in the goods channel by the staff is offset, stop the conveyor belt in time when the offset is detected, and remind the staff to correct, thereby reducing the occurrence of the phenomenon that the article is stuck or overturned in the goods channel.

[0068] Specifically, two offset sensors are symmetrically arranged between the first and second outermost positions of each goods channel, and preferably, the two offset sensors are arranged on the left and right sides of the goods channel respectively. The method for detecting whether the placed article is askew includes: if the time difference between the signals received by the two offset sensors is less than or equal to a first preset time, it is determined that the article is not askew; and if the time difference between the signals received by the two offset sensors is greater than the first preset time, it is determined that the article is askew. The first preset time can be set according to the actual movement speed of the conveying belt, for example, when the actual movement speed of the conveying belt is 0.1 m / s, the first preset time is set to 200 ms.

[0069] In the embodiment, when the article is conveyed into the goods channel, the two offset sensors will detect the signals of the article respectively, and by comparing the time difference between the two signals, the position difference of the article on both sides can be determined, so that whether the article is askew in the goods channel can be quickly and accurately determined.

[0070] Further, after it is determined that the article is not askew, the method further includes: when the signals of the two offset sensors disappear and a second preset time elapses, it is determined that the outermost position is vacant. The second preset time can be set according to the actual movement speed of the conveying belt, for example, when the actual movement speed of the conveying belt is 0.1 m / s, the second preset time is set to 400 ms. In the embodiment, the offset sensors can be used to determine whether the article is conveyed inward to the target position (i.e., the second position in the direction from the outside of the goods channel to the inside of the goods channel), so as to ensure that the outermost position is vacant.

[0071] A distance sensor can be arranged at the top of the outermost position of each goods channel, for detecting whether an article is placed in the outermost position of the goods channel. Preferably, after the distance sensor detects the signal of the article and elapses a certain time (e.g., 1 second), it is determined that the article is placed in position, and it is considered that an article is placed in the outermost position of the goods channel.

[0072] Of course, other means can also be used to detect whether an article is placed in the outermost position of the goods channel, for example, a weight sensor can be arranged at the bottom of the outermost position of the goods channel, and if the weight sensed by the weight sensor is greater than a preset weight, it is determined that an article is placed in the outermost position of the goods channel.

[0073] In an embodiment, after entering the restocking mode, further comprising: recording the number of times the control chip reads the signal of the distance sensor detecting the presence of an article as the current number of articles restocked in the goods channel. In the restocking mode, if no article is detected to be offset, the control chip reads the signal of the distance sensor at the top of the goods channel to determine whether an article is placed at the outermost position of the goods channel. That is, when restocking any goods channel, the control chip records once for each time it reads the signal that an article is placed at the outermost position of the goods channel. Specifically, when the control chip reads the signal that an article is placed at the outermost position of the goods channel in the restocking mode, it can send a first signal to the conveyor motor to make the conveyor motor run in a first direction. Counting the number of times the control chip reads the signal that an article is placed at the outermost position of the goods channel can achieve counting. The embodiment can count the number of articles restocked in a single goods channel in real time, which facilitates the staff to understand the restocking information in the cabinet in real time, making the information clearer and facilitating management.

[0074] In the restocking mode, the control chip reads the signal of the distance sensor and sends a first signal to the conveyor motor to make the conveyor motor run in a first direction when it confirms that an article is placed at the outermost position of the goods channel, so as to deliver the article inside the goods channel until the outermost position is empty. Therefore, in the restocking mode, the number of articles restocked in the goods channel can be counted by recording the number of times the control chip reads the signal that an article is placed at the outermost position of the goods channel.

[0075] In the delivery mode, the control chip also reads the signal of the distance sensor and sends a second signal to the conveyor motor to make the conveyor motor run in a second direction when it confirms that there is no article at the outermost position of the goods channel, so as to push the internal article out.

[0076] A zero point sensor can be arranged at the preset position of the innermost side of each goods channel to detect whether the push plate on the conveyor belt reaches the preset position of the innermost side of the goods channel. Specifically, the zero point sensor can be a laser transmission sensor. In the restocking mode, when the conveyor motor delivers the article inside the goods channel, the push plate also moves inside the goods channel with the conveyor belt. When the push plate reaches the position of the zero point sensor, the laser signal disappears, indicating that the push plate reaches the preset position of the innermost side of the goods channel, and the conveyor motor stops running.

[0077] The restocking control scheme of the intelligent vending cabinet is described below in conjunction with a specific embodiment. However, it should be noted that the specific embodiment is only used to better illustrate the present application and does not constitute an improper limitation on the present application. The same or corresponding terms as in the above embodiments are not described again.

[0078] Reference Figure 2 Fig. 1 is a schematic view of the structure of the goods channel of the intelligent vending cabinet, which comprises: a goods channel 1, a conveyor belt 2, a push plate 3, an article 4, a distance sensor 5, a zero point sensor 6, and an offset sensor 7.

[0079] The push plate 3 is fixed on the conveying belt 2, when the goods channel 1 is completed, the push plate 3 is located at the preset position (i.e. zero position) of the innermost side of the conveying belt 2, when the goods need to be delivered, the conveying belt 2 motor is forward rotated, the push plate is moved outward and the goods 4 are pushed out.

[0080] The distance sensor 5 is installed at the top of the outermost position of the goods channel 1, which is used to detect whether there is goods at the outermost position of the goods channel 1. In the delivery mode, when the distance sensor 5 detects that there is no goods at the outermost position, a forward rotation signal is sent to the conveying belt 2 motor to push the goods out. In the restocking mode, when the distance sensor 5 detects that there is goods at the outermost position, a reverse rotation signal is sent to the conveying belt 2 motor to transport the goods to the inner side of the goods channel 1.

[0081] The zero point sensor 6 is installed on both sides of the preset position of the innermost side of the goods channel 1, which is a laser transmission sensor. In the restocking mode, the conveying belt 2 motor is reversed, and the push plate 3 is also moved to the inner side of the goods channel 1. When the push plate 3 reaches the position of the zero point sensor 6, the laser signal disappears, indicating that the push plate 3 has reached the preset position of the innermost side of the goods channel 1, and the conveying belt 2 motor stops running.

[0082] The offset sensor 7 is installed on both sides of the first position and the second position of the outermost side of the goods channel 1. In the restocking mode, when the goods are transported to the inner side of the goods channel 1, the offset sensors 7 on both sides will detect the signals of the goods respectively. By comparing the time difference of detecting the two signals, it can be judged whether the position of the goods in the goods channel 1 is skewed.

[0083] Reference Figure 3 The figure is a schematic diagram of the restocking process of the intelligent vending cabinet, which includes the following steps:

[0084] S301, start.

[0086] S303, the staff places the goods at the outermost position of the goods channel, and at this time the distance sensor at the top of the outermost position of the goods channel detects the product signal.

[0087] S304, judge whether the product signal is delayed for 1 second, if yes, confirm that the goods are placed in place, enter S305, if not, return to S303.

[0088] S305, judge whether the push plate is at the zero position? If yes, it indicates that the goods channel has been completed, no reverse signal is sent to the conveying belt motor, and S316 is entered, if not, S306 is entered.

[0089] S306, send a reverse signal to the conveying belt motor to make the conveying belt motor reverse.

[0090] S307, when the motor reverses to convey the goods inside the goods channel, the offset sensors on both sides will receive signals.

[0091] S308, whether the time difference of the signals received by the two offset sensors is less than 200ms, if yes, the positions of the goods on both sides are within 20mm, it is considered that the goods are not placed askew, and S309 is entered, if not, S317 is entered.

[0092] S309, the conveyor belt motor continues to reverse to move to the target position.

[0093] S310, the offset sensor signal disappears and delays for 400ms, at this time, the goods just replenished move from the outermost first position to the outermost second position, the outermost first position is empty, waiting for the next goods.

[0094] S311, the conveyor belt motor stops reversing.

[0095] S312, whether the push plate is at the zero position, if yes, S313 is entered, if not, S303 is returned to continue the replenishment process, and the distance sensor detects the product signal, if the staff actively confirms that the replenishment is completed, the goods channel conveyor belt motor is reversed to convey the goods in the outermost second position to the outermost first position, ensuring that there are goods in the outermost position, and the goods channel replenishment mode ends and enters the selling mode.

[0096] S313, a pop-up window prompts the staff to confirm "replenishment complete".

[0100] S317, the conveyor belt motor stops reversing, and a pop-up window prompts the staff to correct the askew goods.

[0101] S318, the staff confirms the completion of the correction, and then S309 is entered.

[0102] S319, the conveyor belt motor is reversed to convey the goods in the outermost second position to the outermost first position, ensuring that there are goods in the outermost position, and then S315 is entered.

[0103] S320, end.

[0104] In the replenishment mode, the control chip reads the number of times that the distance sensor detects the object signal and updates in real time to obtain the current number of replenished objects in the goods channel, so that the user can know the replenishment information in the cabinet in real time, and the objects in a single goods channel are counted in real time, the information in the cabinet is clearer, and the management is facilitated.

[0105] The embodiment adds the reverse function of the conveyor belt motor, the distance sensor, the zero point sensor and the offset sensor, so that the conveyor belt is not manually pushed back to the original point, the replenishment efficiency is effectively improved, the replenishment difficulty is reduced, and the automation, intelligence and simplification of the intelligent vending cabinet replenishment are realized. Specifically, the reverse function of the conveyor belt motor is added, so that the object can be automatically sent into the goods channel when the object is detected; the distance sensor is added, the control chip can read the distance sensor signal and send a reverse signal to the conveyor belt motor to act, and the number of replenished objects in the goods channel can be counted by recording the number of times that the control chip reads the distance sensor signal; the zero point sensor is added, so that the push plate of the conveyor belt can be accurately positioned to the zero point position and the situation that the push plate of the conveyor belt is stuck is prevented; the offset sensor is added, so that whether the placed object is offset can be detected, and the conveyor belt motor is stopped when the offset is detected, so as to remind the staff to correct and reduce the phenomenon that the object is stuck or turned over in the goods channel.
